Description

A self-generated tide level observation device for tide wells

technical field

The invention relates to a self-generating tide level observation device for tide-gauging wells, belonging to the technical field of energy and power.

Background technique

Tide level forecasting is an important element of ocean security, and changes in coastal tide levels are directly related to the propagation of entry and exit ports, marine and coastal engineering design, storm tide forecasting, and tidal power generation. It can reduce the losses caused by tidal changes to the fishery, restore the disaster prevention and mitigation environment, and ensure the safety of fishing vessels.

A tide well is a fixed and reliable facility that provides long-term fixed-point tide testing. The standard to measure the pros and cons of tide wells is usually wave-absorptive and tide-accompanying. Tide wells were originally designed to help measure tidal changes over a few meters. Although the tidal phenomenon is a fundamental marine dynamic phenomenon in the shallow sea area, with the continuous development of science, the need for climate change and satellite data verification has put forward higher requirements for the measurement accuracy of tide wells. For the entire tide well, its performance is reflected in the wave absorption and tide-accompanying properties of the inlet hole. If the design is too large, the filtering performance will be poor, and the tidal self-recording curve will have a wide band record, so the observed tidal level value is not accurate, but also brings difficulties to the data collation. On the contrary, if the water inlet hole is designed If it is too small, although the filtering performance is enhanced, some fluctuations that should not be filtered out are filtered out, and although the recorded curve is smooth, there is a lag in the recorded tides, resulting in obvious inconsistencies in the tidal levels inside and outside the well.

At present, the most widely used device for tide level observation is the float-type tide well. The main structures are tide wells, buoys, and recording devices. Its advantages lie in its sturdiness and durability, and its filtering performance is good, but its disadvantages are also relatively obvious. In order to ensure the accuracy and effectiveness of tide level observation, it is necessary to pay attention to that the time interval of the variation of the out-of-tolerance inside and outside the tide well should not be too large, which leads to the inability of the two to maximize their effect. Therefore, a self-generating tidal level measurement device for tide-gauge wells is developed, so that the tide-gauge well device can generate electricity while observing the tide level, and at the same time amplify the filter hole, and calculate the average tide level of the tidal level change through the change of current and voltage, which is Lay the foundation for the research and application of high operability and high effectiveness of the tide detection well device.

Detailed ways

In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.

As shown in Fig. 1-Fig. 11, a self-generated tide level observation device for tide-checking wells includes a bracket 1, a filter hole 2, a well wall 3, a first helical coil group 4, and a first magnet 5 with a floating body , the second helical coil group 6, the second magnet 7 with floating body, the third helical coil group 8, the third magnet 9 with floating body, and the current output storage system 10;

The support 1 is fixed to the bottom of the tide-gauge well, and the water level of the filter port 2 is controlled near the lowest tide level in the area. The filter port 2 has a larger diameter than ordinary tide-gauge wells, and responds sensitively to the change of tide level, increasing the self-generated power and the observation accuracy. , the diameter of the filter hole 2 is larger than that of the common tide well, which weakens its wave elimination effect, but the fluctuation of the water surface caused by the change of tide level increases the movement range of the magnet with the floating body, increases the power generation, and at the same time can more quickly Track the change of tide level; the well wall 3 directly separates the tide level observation system from the water level outside the well, and there are multiple sets of spiral coil groups in the well wall 3, and a magnet with a floating body is arranged in the spiral coil group. The group and the magnet with the floating body are connected with the current output storage system 10; when the tide level changes, the magnet with the floating body rises in the spiral coil group driven by the buoyancy of the respective floating body, according to the difference of the current generated in the current output system by the electromagnetic devices of each group The combination judges the size of the current tide level, and the generated electric energy is stored in the battery for use by the information transmission terminal.

In this embodiment, there are at least three sets of the helical coil group, namely a first helical coil group 4, a second helical coil group 6, and a third helical coil group 8, and each helical coil group is provided with a floating body. Magnets, the first magnet 5 with floating body is set in the first helical coil group 4, the second magnet 7 with floating body is set in the second helical coil group 6, the third magnet 9 with floating body is set in the third helical coil group 8, The three sets of the helical coil sets are dislocated and connected in the well wall 3 . 2 to 4 are schematic diagrams of an electromagnetic device, which consists of a first helical coil group 4 and a magnet 5 with a floating body, a second helical coil group 6 and a magnet 7 with a floating body, a third helical coil group 8 and a floating body. The three sets of coil magnets are dislocated in the tide well, and the heights of the three magnets and the bottom of the coil are the same at the initial moment.

As shown in the schematic diagrams of the arrangement of different turns of each coil group in Figs. 6-8, the first helical coil group 4, the second helical coil group 6, and the third helical coil group 8 are composed of A, B, C, D, E is composed of 5 parts with different turns. The first spiral coil group 4 is a turn number interval every 1.2m, and the coil turns are arranged as ABCDE. The second spiral coil group 6 is a turn number interval every 0.24m. The number of turns is arranged as ABCDE, ABCDE... A total of 5 cycles, the third spiral coil group 8 is a turn number interval every 0.048m, and the number of coil turns is arranged as ABCDE, ABCDE... A total of 25 cycles, three sets of spiral coil groups are the same starting height. When the tide level rises, the first magnet 5 with a floating body, the second magnet with a floating body, and the third magnet 9 with a floating body spirally rise slowly in the coil driven by the floating body, and the electromagnetic induction generates current and transmits it to the current output storage system 10 , using the stored electrical energy to transmit the real-time current fluctuation pattern to the terminal for tidal level observation through the signal sending terminal to observe and record the tidal level. Due to the same state of motion of the magnets, the arrangement and combination of parts with different turns at any two heights are not the same. There are 125 combinations of current fluctuation diagrams generated by the three sets of coils, corresponding to an observation accuracy of 4.8 under a 6m tidal range. cm.

Comparing the waveforms observed on the previous day, it is known that the moving speed of the floating body is similar, and the output voltage waveform of the spiral coil group is basically unchanged. As shown in Fig. 9-Fig. 11, the voltage diagrams output by the first, second and third helical coil groups recorded at a certain moment in the terminal are respectively shown. 5 different coil turns correspond to 5 different waveforms. The initial height of the coil is 0. Assume that the coil turns corresponding to the three voltage waveform diagrams in Figure 9-Figure 11 are BCE respectively. According to Figure 6-Figure 8 The tidal level corresponding to this moment can be found by the arrangement of the middle coil, which is 1.30m. In this coil arrangement, the tidal level at the corresponding moment can be found according to the arrangement and combination of the voltage map at any moment.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the technical principle of the present invention, several improvements and modifications can also be made. These improvements and modifications It should also be regarded as the protection scope of the present invention.
