Abstract

The present invention discloses an equipment-carrying floating device, in which a submerged body is arranged on a column; and a first ballast tank is provided in the submerged body, so that by loading ballast into the first ballast tank, the center of gravity height of the equipment-carrying floating device as a whole is lowered, and the swing amplitude of the equipment-carrying floating device with the ups and downs of waves is reduced, so that the stability of the entire device after being towed and carrying equipment is better. At the same time, the cross-sectional area _S0 of the connecting part gradually increases from one end close to the second submerged part to the other end, which effectively increases the contact area between the submerged body and the seawater, so that the friction resistance and viscous resistance between the submerged body and the seawater are increased, which is conducive to improving the motion damping of the device at sea. In addition, when the submerged body enters the water, the water pressure perpendicular to the inclined surface on the connecting part can be divided into a supporting force in the vertical direction and a circumferential force in the horizontal direction; when the device generates a tilting moment under the action of an external force, the vertical supporting force of the connecting part will generate a restoring moment to prevent the device from continuing to tilt.

Description

Equipment carrying floating device

Technical Field

The invention relates to the technical field of carrying platforms, and in particular to an equipment carrying floating device.

Background technique

There are two main types of offshore wind power installations: fixed and floating. Floating installations refer to installations where the foundation platform is not in direct contact with the seabed, but is connected to the seabed through a floating platform and mooring system. The wind turbines float and move freely with the floating platform within the control range of the local area. Different floating platform forms can adapt to different marine environments.

Traditional floating devices use multiple columns with water pressure plates arranged at the bottom of the columns. However, the first ballast tank of the platform is arranged inside the slender columns, which results in a high center of gravity of the ballast weight and poor seakeeping, which leads to a large movement amplitude of the device in the waves, seriously affecting the normal operation of the onboard equipment.

Summary of the invention

Based on this, it is necessary to provide a floating device for equipment to lower the center of gravity of the entire device, improve the wave resistance of the device, and ensure the stable operation of the equipment.

The technical solution is as follows:

A floating device for carrying equipment comprises: a carrying structure, the carrying structure is used to carry equipment, the carrying structure comprises a column; and a submerged body, the column is arranged on the submerged body, a first ballast tank is arranged in the submerged body, the first ballast tank is used to load ballast, wherein the submerged body comprises a first submerged part, a second submerged part, and a connecting part surrounded by the first submerged part and the second submerged part, the first submerged part is connected to the column, and the cross-sectional area _S0 of the connecting part gradually increases from one end of the connecting part close to the second submerged part to one end of the connecting part close to the first submerged part.

The above-mentioned equipment-carrying floating device has a submerged body arranged on a column; and a first ballast tank is provided in the submerged body. Thus, by loading ballast into the first ballast tank, the center of gravity of the device is transferred to the bottom of the device, the center of gravity height of the equipment-carrying floating device as a whole is lowered, and the swing amplitude of the equipment-carrying floating device with the ups and downs of waves is reduced, so that the stability of the entire device after being towed and carrying equipment is better. At the same time, the submerged body includes a connecting part, and the cross-sectional area _S0 of the connecting part gradually increases from one end close to the second submerged part to the other end. It can be seen that the surface of the connecting part of this scheme is inclined, so that the cross-sectional area of the first submerged part is effectively increased, and the contact area between the submerged body and the seawater is increased, so that the friction resistance and viscous resistance between the submerged body and the seawater are increased, which is conducive to improving the motion damping of the equipment-carrying floating device at sea. In addition, the cross-sectional area _S0 of the connection part gradually increases from one end close to the second submerged part to the other end. Therefore, when the submerged body enters the water, the water pressure perpendicular to the inclined surface on the connection part can be divided into a supporting force in the vertical direction and a circumferential force along the horizontal direction. When the floating device carried by the equipment generates a tilting moment under the action of an external force, the vertical supporting force and axial force of the connection part will generate a restoring moment to prevent the device from continuing to tilt. Especially after the device tilts at a small angle, the unbalanced supporting force on both sides of the connection part will produce a more beneficial effect, further improving the restoring moment of the floating device carried by the equipment to prevent tilting, thereby effectively improving the wavekeeping performance of the device and ensuring the stable operation of the equipment.

The principle and effect of the present invention are further described below in combination with the above scheme:

In one embodiment, the cross-sectional area _S1 of the first submerged portion is greater than the cross-sectional area _S2 of the pillar and the cross-sectional area _S3 of the second submerged portion.

In one embodiment, the first submerged portion includes a first side surface, the second submerged portion includes a second side surface, one end of the connecting portion is connected to the first side surface, and the other end of the connecting portion is connected to the second side surface.

In one embodiment, the first submerged portion further includes a pressure-bearing surface, the first side surface is disposed around the pressure-bearing surface, and the column is disposed on the pressure-bearing surface.

In one of the embodiments, the equipment-carrying floating device further includes a first reinforcement member, wherein the first reinforcement member is connected between the submerged body and the column.

In one embodiment, there are four first reinforcement members, and the four first reinforcement members are respectively located around the column.

In one embodiment, there are more than two columns and more than two submerged bodies, and the columns and the submerged bodies are arranged in a one-to-one correspondence.

In one of the embodiments, the equipment-carrying floating device further includes a connecting member, wherein the connecting member is connected between two adjacent columns.

In one of the embodiments, the equipment-carrying floating device further includes a second reinforcement member, and the second reinforcement member is disposed between the connecting member and the column.

The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

In one embodiment, please refer to FIG. 1 and FIG. 4 , a floating device 100 for carrying equipment includes: a carrying structure 110 and a submerged body 120. The carrying structure 110 is used to carry equipment, and the carrying structure 110 includes a column 111. The column 111 is arranged on the submerged body 120, and a first ballast tank 121 is arranged in the submerged body 120. The first ballast tank 121 is used to load ballast. Among them, the submerged body 120 includes a first submerged part 122, a second submerged part 124, and a connecting part 123 surrounded between the first submerged part 122 and the second submerged part 124. The first submerged part 122 is connected to the column 111. The cross-sectional area _S0 of the connecting part 123 gradually increases from the end of the connecting part 123 close to the second submerged part 124 to the end of the connecting part 123 close to the first submerged part 122.

The above-mentioned equipment-carrying floating device 100 is provided with a submerged body 120 on a column 111; and a first ballast tank 121 is provided in the submerged body 120. Thus, by loading ballast into the first ballast tank 121, the center of gravity of the device is transferred to the bottom of the device, the center of gravity height of the equipment-carrying floating device 100 as a whole is reduced, and the swing amplitude of the equipment-carrying floating device 100 with the ups and downs of waves is reduced, so that the stability of the entire device after being towed and carrying equipment is better. At the same time, the submerged body 120 includes a connecting portion 123, and the cross-sectional area _S0 of the connecting portion 123 gradually increases from one end close to the second submerged portion 124 to the other end. It can be seen that the surface of the connecting portion 123 of the present solution is inclined, so that the contact area between the submerged body 120 and the seawater is effectively increased, so that the friction resistance and viscous resistance between the submerged body 120 and the seawater are increased, which is conducive to improving the motion damping of the equipment-carrying floating device 100 at sea. In addition, the cross-sectional area _S0 of the connection part 123 gradually decreases from one end close to the column 111 to the other end. Therefore, when the submerged body 120 enters the water, the water pressure of the seawater can be divided into a vertical support force and a horizontal circumferential force. When the device 100 generates a tilting moment under the action of an external force, the vertical support force of the connection part 123 will generate a restoring moment to prevent the device 100 from continuing to tilt. In particular, after the device 100 has tilted at a small angle, the connection part 123 prevents the tilted submerged body 120 from entering the water deeper, the water pressure increases, and the vertical projection area (contact area) increases, so the restoring moment generated on the inclined surface to prevent tilting is significantly increased, so that the wave resistance performance of the device is effectively improved, ensuring the stable operation of the equipment. In addition, the equipment-carrying floating device 100 of this embodiment has a simple structure, convenient construction, and few supporting requirements for auxiliary ships; at the same time, it can be arranged in open waters, does not occupy shoreline resources, and can avoid traffic arteries.

It should be noted that the cross-sectional area of the connecting portion 123 should be understood as the area enclosed by the outer surface of the connecting portion 123 on the cross-sectional surface when the connecting portion 123 is cut perpendicular to the axial direction of the connecting portion 123. For ease of understanding, please refer to Figure 3, the cross-sectional area of the connecting portion 123 is the area represented by _S0 in Figure 3.

It should also be noted that the present embodiment does not specifically limit the type of equipment, and the equipment may be a wind turbine, a diesel generator, a gasoline generator or other equipment. At the same time, the present embodiment does not specifically limit the type of ballast, and the ballast may be seawater, sand or other ballast.

Specifically, the first submerged portion 122, the connecting portion 123 and the second submerged portion 124 are an integrated structure, so that the structure of the submerged body 120 is more stable and the production of the submerged body 120 is also facilitated.

Further, please refer to FIG. 1 and FIG. 3 , the cross-sectional area S ₁ of the first submerged part 122 is greater than the cross-sectional area S ₂ of the column 111. It can be seen that the column 111 and the submerged body 120 form a structural form that is small at the top and large at the bottom, light at the top and heavy at the bottom, which is conducive to the center of gravity of the equipment-carrying floating device 100 moving to the bottom of the entire device, making the equipment-carrying floating device 100 more stable at sea. Specifically in this embodiment, the first submerged part 122 and the column 111 are both structures with circular cross-sections or polygonal cross-sections, and the diameter of the first submerged part 122 is more than twice the diameter of the column 111.

Furthermore, the cross-sectional area _S1 of the first submerged portion 122 is also greater than the cross-sectional area _S3 of the second submerged portion 124. Thus, _S1 can be maximized under the condition of limited displacement volume. At the same time, the cross-sectional area of the second submerged portion 124 is set smaller than the cross-sectional area of the first submerged portion 122, so that the connecting portion 123 is more likely to form a variable cross-sectional structure with a larger upper portion and a smaller lower portion, so that the connecting portion 123 is in contact with more seawater.

In one embodiment, please refer to FIG. 3 , the first submerged portion 122 includes a first side surface 1221. The second submerged portion 124 includes a second side surface 1241. One end of the connecting portion 123 is connected to the first side surface 1221, and the other end of the connecting portion 123 is connected to the second side surface 1241. It can be seen that the first submerged portion 122, the connecting portion 123 and the second submerged portion 124 are sequentially transitionally connected, that is, the cross-sectional area of the first submerged portion 122 is greater than or equal to the cross-sectional area of the connecting portion 123, and the cross-sectional area of the connecting portion 123 is greater than or equal to the cross-sectional area of the second submerged portion 124. In this way, the outer surface of the submerged body 120 is a structure that gradually decreases from top to bottom, so that the hydrodynamic characteristics of the submerged body 120 are better. At the same time, the cross-sectional area of the second submerged portion 124 is less than or equal to the cross-sectional area of the connecting portion 123, so as to avoid the second submerged portion 124 being too large and thus covering a part of the connecting portion 123 in the vertical direction, thereby avoiding the friction resistance and viscous resistance between the connecting portion 123 and the seawater due to the reduction of the contact force between the connecting portion 123 and the seawater. In addition, the first side surface 1221 and the second side surface 1241 are provided in this embodiment, which is conducive to increasing the contact area of the submerged body 120 in the horizontal direction. When the submerged body 120 swings with the wind and wave current, the seawater will exert resistance on the first side surface 1221 and the second side surface 1241 in the horizontal direction, preventing the submerged body 120 from swinging with the wind and wave current, thus greatly improving the seakeeping performance of the equipment-carrying floating device 100.

Optionally, the first side surface 1221 and the second side surface 1241 may be cylindrical surfaces, frustum surfaces, triangular prism surfaces, quadrangular prism surfaces, pentagonal prism surfaces or other shaped surfaces.

Further, referring to FIG3 , the first submerged portion 122 further includes a pressure-bearing surface 1222. The first side surface 1221 is disposed on the pressure-bearing surface 1222. The column 111 is disposed on the pressure-bearing surface 1222. Thus, the column 111 is stably installed through the pressure-bearing surface 1222, thereby making the structure of the equipment-carrying floating device 100 more stable.

In one embodiment, please refer to FIG. 1 , the equipment-carrying floating device 100 further includes a first reinforcement member 140. The first reinforcement member 140 is connected between the submerged body 120 and the column 111. In this way, the first reinforcement member 140 is arranged between the submerged body 120 and the column 111, so that the submerged body 120 and the column 111 are stably connected, which is conducive to improving the overall structural strength of the equipment-carrying floating device 100, thereby making the equipment-carrying floating device 100 more stable at sea. At the same time, the first reinforcement member 140 is arranged between the submerged body 120 and the column 111, so that an additional damping structure is added to the submerged body 120, which reduces the submerged body 120 from following the waves, which is conducive to improving the motion damping performance of the equipment-carrying floating device 100, so that the restoring torque of the equipment-carrying floating device 100 becomes larger, thereby making the device more stable at sea, greatly ensuring the stable operation of the equipment. Specifically in this embodiment, the first reinforcement member 140 is an inclined rod structure between the submerged body 120 and the column 111, one end of the inclined rod structure is connected to the column 111, and the other end of the inclined rod structure is connected to the pressure surface 1222. The connection method can be bolt connection, welding or other methods.

Further, please refer to FIG. 1 , there are four first reinforcement members 140. The four first reinforcement members 140 are respectively located around the column 111. In this way, the first reinforcement members 140 are arranged around the column 111, so that the column 111 is subjected to force all around, ensuring that the column 111 is subjected to symmetrical support force, greatly improving the installation stability of the column 111 on the submerged body 120, thereby facilitating the improvement of the structural strength of the equipment-carrying floating device 100. At the same time, four first reinforcement members 140 are arranged between the column 111 and the submerged body 120, so that there are more damping structures on the submerged body 120, which is conducive to improving the motion damping performance of the submerged body 120, thereby making the equipment-carrying floating device 100 more seakeeping and more stable.

In one embodiment, please refer to Figure 1, there are more than two columns 111 and submersibles 120. The columns 111 and submersibles 120 are arranged in a one-to-one correspondence. In this embodiment, the columns 111 are arranged in a one-to-one correspondence, so that the columns 111 are stably supported by the submersibles 120; at the same time, the number of submersibles 120 in the equipment-carrying floating device 100 is increased, so that the motion damping effect of the entire device is better, the restoring torque is larger, and the swing amplitude is smaller, which further improves the stability and wave resistance of the device at sea, thereby ensuring that the carried equipment operates more stably. Specifically in this embodiment, there are three columns 111 and submersibles 120. The submersibles 120 and columns 111 are arranged in a one-to-one correspondence. The three columns 111 are connected to each other.

Further, please refer to FIG. 1 , the equipment carrying floating device 100 further includes a connector 113. The connector 113 is connected between two adjacent columns 111. Thus, the two adjacent columns 111 are tightly connected through the connector 113, thereby improving the structural strength of the equipment carrying floating device 100, which is beneficial to increasing the carrying capacity of the equipment carrying floating device 100, so that the equipment carrying floating device 100 can stably carry more equipment.

Further, please refer to FIG. 1 , the equipment-carrying floating device 100 further includes a second reinforcement member 114. The second reinforcement member 114 is arranged between the connecting member 113 and the column 111. In this way, the connection between the column 111 and the connecting member 113 is reinforced by the second reinforcement member 114, and the structural strength of the equipment-carrying floating device 100 is further improved. At the same time, since a part of the second reinforcement member 114 and the connecting member 113 are both located in the water when the equipment-carrying floating device 100 enters the water, the damping structure of the equipment-carrying floating device 100 is more, so that the motion damping effect of the entire device in the seawater is better, which is conducive to ensuring that the entire device floats stably in the seawater. Specifically in this embodiment, there are two second reinforcement members 114, one of which is arranged between the connecting member 113 and one of the columns 111, and the other reinforcement member is arranged between the connecting member 113 and another column 111. In this way, through reasonable structural design, the structure of the equipment-carrying floating device 100 is more stable.

In one embodiment, please refer to FIG. 1 , a second ballast tank 1111 is further provided in the column 111, and the second ballast tank 1111 is used to load ballast, so that by loading ballast into the second ballast tank 1111, the draft of the equipment-carrying floating device 100 in seawater is reduced, which is beneficial to reduce the center of gravity height of the equipment-carrying floating device 100, and greatly improves the seakeeping performance of the equipment-carrying floating device 100. The ballast can be seawater, sand or other ballast.

In one embodiment, please refer to FIG. 1 , the carrying structure 110 further includes a deck 112. The deck 112 is mounted on the columns 111, and the deck 112 is used to carry equipment. It can be seen that the deck 112 is stably installed through the columns 111, so that the equipment is stably carried and the equipment is ensured to operate more stably. Specifically in this embodiment, there are three columns 111, and the deck 112 is mounted on three columns 111. At the same time, a mounting frame 115 is provided on the deck 112, and the mounting frame 115 is used to carry equipment.

In one embodiment, referring to FIG. 1 and FIG. 2 , the equipment-carrying floating device 100 further includes a mooring structure 130. The mooring structure 130 is disposed on the carrying structure 110. Thus, through the mooring structure 130, the carrying structure 110 can stably float on the sea without contacting other rigid structures, thereby reducing the impact on the marine environment.

Further, referring to FIG. 2 , the mooring structure 130 includes a fixing seat 132 and a mooring rope 131. The carrying structure 110 includes a deck 112. The fixing seat 132 is disposed on the deck 112, one end of the mooring rope 131 is connected to the fixing seat 132, and the other end of the mooring rope 131 is used to be connected to a seabed anchoring device. In this way, the carrying structure 110 is stably fixed by the mooring rope 131.

Further, please refer to FIG. 1 and FIG. 2 , the mooring structure 130 further includes a first guide wheel 133 and a second guide wheel 134, the first guide wheel 133 is arranged on the deck 112, the second guide wheel 134 is arranged on the submerged body 120, and the mooring rope 131 is respectively wound around the first guide wheel 133 and the second guide wheel 134. In this way, the mooring rope 131 is guided by the two guide wheels to prevent the mooring rope 131 from being easily broken due to friction back and forth on other hard objects. At the same time, the mooring rope 131 is respectively wound around the first guide wheel 133 and the second guide wheel 134, so that the tension of the mooring rope 131 is distributed on the deck 112 and the submerged body 120, so as to prevent the tension from acting only on the deck 112 and causing the equipment-carrying floating device 100 to capsize, which is conducive to improving the stability of the equipment-carrying floating device 100 at sea.

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
