Description

A UAV sea and air environment monitoring device

Technical Field

The present invention belongs to the technical field of offshore wind power equipment monitoring, and in particular relates to an unmanned aerial vehicle (UAV) sea and air environment monitoring device.

Background Art

Offshore wind power is an important development direction of clean and renewable energy. It has good conditions for large-scale development and commercial development prospects. Therefore, it has received widespread attention and developed rapidly worldwide. As an important facility to ensure the safe operation of wind turbines, offshore wind turbine foundations are key supporting structures in offshore wind power facilities. Good protection of offshore wind turbine foundations and submarine cables can ensure the safety of wind turbines and transmission systems, ensure the stable operation of wind power equipment, and is the most effective means to extend the service life of equipment and reduce operating costs.

At present, the offshore wind power monitoring system mainly focuses on the status monitoring and fault diagnosis of generator sets and submarine cables. For example, the invention application with publication number WO2021159919A1 discloses a system and method for monitoring the health status and sea wave acoustic waves of offshore wind turbines. The system includes a first laser emitter and a second laser emitter installed at the bottom of the wind turbine cabin and capable of emitting lasers vertically downward, a telephoto camera installed at the hub, a vibration detection sensor installed on the wind turbine tower, and four acoustic detection sensors arranged at 90° intervals along the circumference of the tower. The above-mentioned first laser emitter, second laser emitter, telephoto camera, vibration detection sensor and acoustic detection sensor are respectively connected to the data collection and conversion module through a transmission module. The monitoring system is based on laser detection and acoustic signal feature detection, which can improve the stability and safety of offshore wind turbines. Moreover, its four acoustic detection sensors are arranged at right angles at 90° intervals, which can effectively detect wind turbine noise even when the wind turbine is yawed.

However, the marine environment and submarine cable dynamic monitoring of wind power pile foundations are currently mostly carried out by shipborne ADCP and side-scan sonar surveys on a quarterly or even annual basis, as well as the use of underwater ROVs or frogmen for structural inspection and submarine cable status observation, which cannot meet the needs of real-time and continuous monitoring. Although there are also solutions to use unmanned ships to replace traditional manpower for high-intensity, high-risk, and repetitive offshore operations, unmanned ships have limited endurance and limited load carrying capacity, and need to be frequently recovered for charging, making it impossible to carry out long-term observations and long-term monitoring of multiple factors near a single pile.

Summary of the invention

The purpose of the present invention is to provide an unmanned aerial vehicle sea and air environment monitoring device, which can realize long-term monitoring of multiple factors of the working environment of offshore wind power equipment and improve the accuracy of monitoring data.

The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

A drone sea and air environment monitoring device includes a data collector, a communication base station and a server. The data collector is connected to the server through the communication base station. The data collector includes a drone. The drone includes a base body. The base body is equipped with sensors, sampling devices, etc., and is used to collect real-time data of multiple environmental indicators of the environment where offshore wind power equipment is located. The obtained data information is fed back to the server through the communication base station, and on-site sampling can be realized.

A photovoltaic assembly is arranged above the base, and the photovoltaic assembly comprises a photovoltaic panel. The photovoltaic panel is bent into an arch shape, and the photovoltaic panel is elastically connected to the base.

By adopting the above technical solution, the setting of photovoltaic modules can ensure the endurance of the drone, extend the working time of the data collector, and avoid the situation where the drone is difficult to return due to insufficient power after a long-distance flight. A variety of sensors are configured on the substrate as needed, and the drone can be used to detect the environmental data around the offshore wind power equipment, and the drone can be used to stop on the water surface to collect water data.

The photovoltaic panel enables the drone to fly for a long time, freeing the data collector from power constraints. The elastic connection between the photovoltaic panel and the substrate can reduce the vibration amplitude of the photovoltaic panel during the drone's flight and reduce the impact on the drone's flight status. The photovoltaic panel protects the substrate and the sensors and samplers installed on the substrate, which helps to ensure the accuracy of the monitoring results.

In addition, the photovoltaic panels are curved in an arched shape, and can be used to obtain light from different angles, improve the utilization of light, and ensure endurance. The arched photovoltaic panels can also reduce the airflow resistance during the flight of the drone. During the flight of the drone, the photovoltaic components can stabilize the center of gravity. When the airflow contacts the drone, the airflow flows along the curved photovoltaic panels and has a downward pressure effect on the photovoltaic components as a whole, thereby improving the center of gravity stability of the drone. Similarly, when the drone stops on the water, the airflow flows through the photovoltaic panels and also has a downward pressure effect to improve the center of gravity stability of the drone on the water.

According to one embodiment of the present invention, a connecting plate is configured on the upper surface of the base, and two photovoltaic panels are symmetrically arranged above the connecting plate; the base is provided with a battery for powering the drone, the connecting plate can be set on the surface of the battery, and the photovoltaic panel can be electrically connected to the battery to store energy for the battery.

The photovoltaic panel is partially covered on the top of the connecting plate, and partially suspended on the outside of the connecting plate; a side plate is arranged on the side of the connecting plate, and the side plate is elastically connected to the suspended part of the photovoltaic panel through a spring or the like.

The photovoltaic panel is partially suspended and its elastic connection structure with the side panel causes it to vibrate under the action of airflow and air pressure, which can reduce the impact of airflow on other components on the substrate, thereby strengthening the protection of different sensors and samplers on the substrate, and making the detection environment of the sensor and sampler relatively stable, which can not only ensure the normal detection of the sensor and sampling of the sampler, but also reduce the impact of airflow on the sensor detection results and the sampling structure of the sampler during the flight of the UAV.

According to an embodiment of the present invention, an elastic shaft is disposed on the side of the connecting plate, the elastic shaft is rotatable, and the elastic shaft abuts against an end of the photovoltaic panel away from the connecting plate.

Furthermore, the elastic shaft includes a rubber column, a rubber strip is arranged outside the rubber column, a plurality of rubber strips are radially arranged on the surface of the rubber column, and one end of the rubber strip away from the rubber column abuts against the lower surface of the photovoltaic panel.

In this way, the elastic shaft can support the photovoltaic panel and prevent the photovoltaic panel from excessive bending or damage under the action of air pressure; and the elastic shaft can reduce the vibration amplitude of the photovoltaic panel through the elastic contact between the rubber strip and the photovoltaic panel.

According to one embodiment of the present invention, an extension plate is arranged on the side of the connecting plate, and the extension plate is arranged along the length direction of the connecting plate, that is, the extension plate extends along the setting direction of the side plate; the end of the elastic shaft body is rotatably matched with the extension plate.

The two ends of the elastic shaft body are respectively sleeved in two symmetrically arranged extension plates, and the elastic shaft body can rotate back and forth relative to the extension plates.

Furthermore, a slide groove extending along the length direction is arranged on the extension plate, and the end of the elastic shaft body cooperates with the slide groove, so that the elastic shaft body can move back and forth along the slide groove.

During the flight of the drone, the rubber column can slide relative to the slide groove of the extension plate, that is, the airflow can be used to push the rubber column and the rubber strip to slide, and the sliding distance of the rubber column is different under the action of airflows of different flow rates, thereby adjusting the contact position of the rubber strip on the end of the photovoltaic panel to adjust the arc-shaped state structure of the photovoltaic panel.

During the sliding and rotating process of the elastic shaft, the vibration of the photovoltaic panel is absorbed, thereby improving the stability of the base and reducing the impact of air pressure changes on sensors and samplers during the ascent or landing of the drone, thereby ensuring the accuracy of the monitoring data.

According to one embodiment of the present invention, a buoyancy component is disposed below the base; thus, the drone can stop on the water surface, which facilitates the data acquisition of the water body data sensor disposed on the base. In addition, when the drone is short of power, it can stop on the water surface and be charged by the photovoltaic component, thus preventing the drone from falling into the water and causing damage to the equipment.

The buoyancy assembly includes a float, which is connected to the base through a frame; a counterweight is arranged below the float, and the float and the counterweight are movably coordinated, so as to ensure that the UAV remains in a vertical state when staying on the sea surface, preventing the UAV from rolling over or capsizing.

The float and the counterweight block work together, so that under the impact of water flow, the counterweight block swings relative to the float, thereby consuming wave energy, reducing the fluctuation of the float on the water surface, and then reducing the up and down displacement of the UAV, preventing the UAV from tipping into the water or coming into contact with a large area of water, thereby strengthening the protection of the UAV.

According to one embodiment of the present invention, a first rod and a second rod are arranged between the float and the counterweight, and the first rod and the second rod are hingedly matched; the counterweight is arranged at the end of the first rod away from the second rod, and the end of the second rod away from the first rod is connected to the float.

According to one embodiment of the present invention, the connecting section between the first rod body and the second rod body is configured with a connecting sleeve, and the connecting section between the first rod body and the second rod body is sleeved inside the connecting sleeve. The connecting sleeve is elastic and can be set as a bellows structure.

Therefore, when the drone is moored on the water surface, the counterweight block, the first rod body and even part or all of the second rod body located below the float may be immersed in the sea water. Under the impact of waves, the first rod body swings relative to the second rod body, which helps to consume wave energy. The setting of the connecting sleeve can not only strengthen the protection of the first rod body and the second rod body, but also bend or stretch during the swing of the first rod body, thereby disturbing the surrounding water body and enhancing the ability to resist waves. In addition, the swing of the first rod body can also help to improve the balance of the local water body below the base, so that the detection environment of multiple sensors is relatively stable, which helps to improve the accuracy of the monitoring results.

Therefore, the UAV sea and air environment monitoring device of the present invention utilizes the cooperation of photovoltaic components and buoyancy components to realize the monitoring of the surrounding environment of single-pile offshore wind power equipment, and the monitoring range can cover long-term monitoring of multiple factors such as the equipment itself and the sea surface environment, underwater environment, and environment above the equipment; and the photovoltaic components and buoyancy components can improve the stability of the data collector, and can also reduce the impact of the surrounding environment on the data collector during the monitoring process, thereby ensuring the accuracy of the monitoring results.

DETAILED DESCRIPTION

The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Example 1

Figures 1 to 5 schematically show a drone sea and air environment monitoring device according to an embodiment of the present invention. As shown in the figure, the monitoring system includes a data collector, a communication base station and a server. The data collector is connected to the server through the communication base station. The data collector includes a drone. The drone includes a base 10. The base 10 is equipped with an automatic water sample collector for collecting water samples from the detection site and carrying the collected water samples to the laboratory for subsequent detection and analysis. The automatic water sample collector can be provided with multiple water sampling pipes as needed to hold water samples collected from different areas of the sea surface, so that different detection sites can be sampled by bottles, avoiding inaccurate detection results caused by mixing of water samples. As needed, the flight path of the drone can be automatically planned, and can also be reasonably adjusted according to the navigation environment of the drone, and the accessories such as the water sampling pipe in the automatic water sample collector can be deep into the seawater 1-10 meters and other different layers for pumping water sampling.

As needed, a variety of sensors can be configured on the substrate 10, such as sensors for detecting water temperature; oil spill sensors for detecting oil spills in offshore wind power installations; in addition, the drone can also be configured with a portable digital ion trap mass spectrometer to achieve on-site sampling and monitoring of diffused organic matter in seawater and air.

After evaluating the performance of small devices such as different models of automatic water sample collectors, sensors, and portable digital ion trap mass spectrometers, and examining indicators such as accuracy, sensitivity, and response time, relevant technical specifications are selected, and then the coordination method and assembly position of the selected small device with the substrate 10 are determined based on the size, weight, and working range of the selected small device.

The photovoltaic module 20 is arranged above the base 10, and the buoyancy module 40 is arranged below. The buoyancy module 40 includes a float 41, which is connected to the base 10 through the frame 11; a counterweight 42 is arranged below the float 41, and the float 41 and the counterweight 42 are movably matched. This ensures that the UAV can maintain a vertical state when staying on the sea surface, preventing the UAV from turning over or capsizing.

The floating body 41 and the counterweight block 42 are in active coordination. In this way, under the impact of the water flow, the counterweight block 42 swings relative to the floating body 41, thereby consuming wave energy, reducing the fluctuation of the floating body 41 on the water surface, and then reducing the up and down displacement amplitude of the drone, preventing the drone from tipping into the water or contacting with a large area of the water body, and strengthening the protection of the drone. In this way, the setting of the photovoltaic component 20 can ensure the endurance of the drone, extend the working time of the data collector, and avoid the situation where the drone is difficult to return due to insufficient power after a long-distance flight, so that the data collector is free from power limitations. The drone can be used to realize long-term monitoring of the environmental data around the offshore wind power equipment, and the drone can be used to stop on the water surface to collect water body data. The drone can stop on the water surface, which is convenient for the sensor for water body data collection set on the base 10 to obtain data. In addition, when the drone is insufficiently powered, it can be stopped on the water surface without returning to the base station or land, and the photovoltaic component 20 can be used for charging to avoid the drone falling into the water and causing equipment damage.

The base 10 is provided with a battery for powering the drone, and a connecting plate 22 is provided on the surface of the battery. The photovoltaic module 20 includes a photovoltaic panel 21, and two photovoltaic panels 21 are symmetrically arranged on the top of the connecting plate 22, one on the left and one on the right. The photovoltaic panel 21 can be electrically connected to the battery to store energy for the battery. In addition, the photovoltaic panel 21 partially covers the top of the connecting plate 22, and partially is suspended on the outside of the connecting plate 22. Furthermore, side panels 23 are arranged on both sides of the connecting plate 22, and the side panels 23 and the suspended parts of the photovoltaic panels 21 are elastically connected by springs 24 and the like.

The partially suspended connection structure of the photovoltaic panel 21 causes it to vibrate under the action of air flow and air pressure. The photovoltaic panel 21 is elastically connected to the base 10, which can reduce the vibration amplitude of the photovoltaic panel 21 during the navigation of the UAV, thereby reducing the impact of the airflow on other components on the base 10, strengthening the protection of different sensors and automatic water sample collectors on the base 10, and making the detection environment of the sensor relatively stable, which can not only ensure the normal detection of the sensor, but also reduce the impact of airflow on the sensor detection results during the flight of the UAV, and ensure the smooth progress of sampling.

The photovoltaic panel 21 is curved in an arch shape, and can be used to obtain light from different angles, improve the utilization effect of light, and ensure endurance. In addition, the arched photovoltaic panel 21 can also reduce the airflow resistance during the flight of the drone. During the flight of the drone, the photovoltaic module 20 can have a stabilizing effect on the center of gravity. When the airflow contacts the drone, the airflow flows along the arc-shaped photovoltaic panel 21 and has a downward pressure effect on the photovoltaic module 20 as a whole, thereby improving the center of gravity stabilization effect of the drone. Similarly, when the drone stops on the water surface, the airflow flows through the photovoltaic panel 21 and also has a downward pressure effect to improve the center of gravity stabilization effect of the drone on the water surface. In addition, the photovoltaic panel 21 is set to an arch shape, which can reduce the influence of the upper airflow on the lower substrate 10 and sensors, automatic water sample collectors, etc., and ensure the relative stability of the monitoring data collection environment.

An elastic shaft 30 is disposed on the side of the connecting plate 22 . The elastic shaft 30 is rotatable and abuts against an end of the photovoltaic panel 21 away from the connecting plate 22 .

Furthermore, the elastic shaft 30 includes a rubber column 31 , and a rubber strip 32 is disposed outside the rubber column 31 . A plurality of rubber strips 32 are radially arranged on the surface of the rubber column 31 , and one end of the rubber strip 32 away from the rubber column 31 abuts against the lower surface of the photovoltaic panel 21 .

In this way, the elastic shaft 30 can support the photovoltaic panel 21, and prevent the photovoltaic panel 21 from being excessively bent or damaged under the action of air pressure; and the elastic shaft 30 can reduce the vibration amplitude of the photovoltaic panel 21 through the elastic contact between the rubber strip 32 and the photovoltaic panel 21. In other words, the setting of the elastic shaft 30 ensures that the photovoltaic panel 21 forms an arc layout and converts energy with light of different illumination, and on the other hand, ensures the arc state of the photovoltaic panel 21 and reduces vibration.

An extension plate 25 is disposed on the side of the connecting plate 22 . The extension plate 25 is disposed along the length direction of the connecting plate 22 , that is, the extension plate 25 extends along the setting direction of the side plate 23 . The end of the elastic shaft 30 is rotatably matched with the extension plate 25 .

Two ends of the elastic shaft body 30 are respectively sleeved in two symmetrically arranged extension plates 25 , and the elastic shaft body 30 can rotate back and forth relative to the extension plates 25 .

Furthermore, a slide groove 26 extending along the length direction is disposed on the extension plate 25 , and the end of the elastic shaft body 30 cooperates with the slide groove 26 , so that the elastic shaft body 30 can move back and forth along the slide groove 26 .

During the flight of the drone, the rubber column 31 can slide relative to the slide groove 26 of the extension plate 25, that is, the airflow can be used to push the rubber column 31 and the rubber strip 32 to slide, and the sliding distance of the rubber column 31 is different under the action of airflows of different flow rates, thereby adjusting the contact position of the rubber strip 32 on the end of the photovoltaic panel 21 to adjust the arc state structure of the photovoltaic panel 21 to ensure the utilization rate of light.

During the sliding and rotating process of the elastic shaft 30, the vibration of the photovoltaic panel 21 is absorbed, thereby improving the stability of the base 10, reducing the impact of air pressure changes on sensors, automatic water sample collectors, etc. during the ascent or landing of the drone, and ensuring the accuracy of the monitoring data. During the sliding and rotating process of the elastic shaft 30, it can also drive the flow of surrounding gas, that is, form disturbances on the gas around the base 10, so that during the flight of the drone, the impact of the strong, single-direction airflow on the base 10 can be avoided.

In addition, the suspended end of the photovoltaic panel 21 is in contact with the rubber strip 32, etc., and the gap between them can form an air flow space, which helps to form noise and drive away surrounding creatures.

The unmanned aerial vehicle sea and air environment monitoring device of this embodiment utilizes the cooperation of the photovoltaic module 20 and the buoyancy module 40 to realize the monitoring of the surrounding environment of the single-pile offshore wind power equipment, and the monitoring range can cover the long-term monitoring of multiple factors such as the equipment itself and the sea surface environment, the underwater environment, and the environment above the equipment; and the photovoltaic module 20 and the buoyancy module 40 can improve the stability of the data collector, and can also reduce the impact of the surrounding environment on the data collector during the monitoring process, thereby ensuring the accuracy of the monitoring results.

Example 2

FIG6 to FIG8 schematically show a drone sea and air environment monitoring device according to another embodiment of the present invention, which is different from Example 1 in that:

A first rod 43 and a second rod 44 are arranged between the float 41 and the counterweight 42. The first rod 43 and the second rod 44 are hingedly matched. The counterweight 42 is arranged at the end of the first rod 43 away from the second rod 44. The end of the second rod 44 away from the first rod 43 is connected to the float 41.

The connecting section between the first rod body 43 and the second rod body 44 is provided with a connecting sleeve 45 . The connecting section between the first rod body 43 and the second rod body 44 is sleeved inside the connecting sleeve 45 . The connecting sleeve 45 is elastic and can be configured as a bellows structure.

Therefore, when the drone is moored on the water surface, the counterweight 42, the first rod 43 and even part or all of the second rod 44 located below the float 41 may be immersed in the seawater. Under the impact of waves, the first rod 43 swings relative to the second rod 44, which helps to consume wave energy. The setting of the connecting sleeve 45 can not only strengthen the protection of the first rod 43 and the second rod 44, but also bend or stretch during the swing of the first rod 43, thereby disturbing the surrounding water and enhancing the ability to resist waves. In addition, the swing of the first rod 43 also helps to improve the balance of the local water body below the base 10, so that the detection environment of multiple sensors is relatively stable, which helps to improve the accuracy of the monitoring results.

Furthermore, the first rod body 43 is provided with an annular adjusting member 50, and the first rod body 43 is sleeved inside the adjusting member 50. An adjusting cavity is arranged around the inside of the adjusting member 50, and the adjusting cavity is connected with the inside and outside of the adjusting member 50, so as to reduce the impact of waves on the counterweight block 42, the floating body 41, etc.

Specifically, the adjusting member 50 includes an inner shell 51 and an outer shell 52 arranged inside and outside, and an adjusting base ring 53 and a bottom ring plate 54 arranged correspondingly above and below are connected between the inner shell 51 and the outer shell 52. The inner shell 51, the outer shell 52, the adjusting base ring 53 and the bottom ring plate 54 are connected to form a three-dimensional structure, and the interior of the three-dimensional structure is the adjusting cavity. The outer shell 52 is provided with a first through hole 55, and the inner shell 51 is provided with a second through hole 56, so that the communication between the adjusting cavity and the outside can be ensured.

In addition, the adjustment base ring 53 is provided with a buffer block, and a plurality of the buffer blocks are evenly dispersed on the surface of the adjustment base ring 53. In this way, the buffer blocks are used to divide the flowing water multiple times, which helps to cause the water flowing through the surface of the adjustment base ring 53 to form a slow flow, improve the stability of the water body under the float 41, reduce the impact of the high-speed rapids on the multiple sensors and automatic water sample collectors on the substrate 10, and improve the stability of the substrate 10.

A connecting rod 57 extending radially inward is provided inside the bottom ring plate 54, and the other end of the connecting rod 57 cooperates with the first rod body 43. Specifically, a fixing ring is provided on the outside of the first rod body 43, and one end of the connecting rod 57 away from the inner edge of the bottom ring plate 54 is connected to the fixing ring, so as to realize the connection between the adjusting member 50 and the first rod body 43. A rotating sleeve 58 is also provided on the outside of the first rod body 43, and a plurality of blades 59 are arranged around the outside of the rotating sleeve 58. The rotating sleeve 58 can drive the blades 59 to rotate outside the first rod body 43, and the rotating sleeve 58 and the blades 59 are both arranged inside the inner shell 51, above the bottom ring plate 54 and the connecting rod 57. In addition, a buffer block can also be provided on the surface of the bottom ring plate 54 to further promote the slow flow of the water body.

In this way, when the drone is flying at low altitude or stranded on the sea, the counterweight 42, the first rod 43, and even part or all of the second rod 44 located below the float 41 may be immersed in seawater. At this time, seawater is immersed in the adjustment cavity inside the adjustment member 50. Under the impact of the water flow, the rotating sleeve 58 drives the fan blade 59 to rotate, which can further promote the water to enter the adjustment cavity through the second through hole 56 and be discharged from the inside of the adjustment cavity through the first through hole 55, thereby accelerating the mixing of the water below the float 41. Further, the second through hole 56 is a long strip, willow leaf, crescent or other similar shapes, and multiple second through holes 56 are evenly dispersed on the surface of the inner shell 51, and the length direction of the second through hole 56 is inclined to the axis of the inner shell 51. In this way, the flow direction of the water entering the adjustment cavity through the second through hole 56 is different, but under the restraint of the inner shell 51 and the outer shell 52, the water with different flow directions can be quickly mixed and the water energy can be reduced, thereby helping the water to quickly stabilize.

That is to say, the second through hole 56 and the regulating cavity can be used to rectify the water flow entering the regulating cavity, change the flow direction of the water body below the float 41, and help reduce the flow rate of the water body below the float 41, thereby reducing the floating amplitude and floating frequency of the float 41, thereby improving the stability of the drone on the water surface. The coordination of the regulating member 50 with the first rod body 43 and the second rod body 44 can ensure the relative stability of the sensor and the automatic water sample collector on the base 10, and can improve the balance of the sensor detecting the water body, ensure the reliability of the water sample obtained by the automatic water sample collector, and thus improve the accuracy of the monitoring data.

In addition, since the adjusting member 50 can allow water to enter its shell, the position of the adjusting member 50 can be changed during the swinging of the first rod 43 relative to the second rod 44, so that the water discharged from the adjusting member 50 has a different flow angle from the external water. This can, on the one hand, slow down the flow velocity around the first and second rods 44, and on the other hand, can utilize the first rod 43 and the second rod 44 to form water flows in different directions to interfere with the movement of organisms around the float 41, thereby achieving a driving effect.

The conventional operations in the operating steps of the present invention are well known to those skilled in the art and will not be described in detail here.

The embodiments described above provide a detailed description of the technical solutions of the present invention. It should be understood that the above descriptions are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, supplements or similar substitutions made within the scope of the principles of the present invention should be included in the protection scope of the present invention.
