Description

Technical Field

[0001] This application belongs to the technical field of floating power stations, and particularly relates to a floating box assembly and a floating power station. Background Art

[0002] The floating photovoltaic power station on water mainly utilizes the water platforms formed by ponds, small and medium-sized lakes, reservoirs, water storage pools, and coal mining subsidence areas, and floats the photovoltaic modules on the water surface for power generation.

[0003] In the prior art, considering the lighting problem, the component floating boxes in adjacent rows will maintain a certain distance, thus forming a walkway. To facilitate the operation and maintenance of the photovoltaic modules in the later stage, aisle plates or aisle floating boxes are usually designed as operation and maintenance channels in the industry.

[0004] However, due to the different volumes, self-weights, and loads of the aisle floating boxes and the component floating boxes provided with photovoltaic modules, it is very difficult for the height of the aisle floating boxes to be the same as that of the component floating boxes provided with photovoltaic modules, resulting in a large shear force at the connection between the floating boxes, which is also not conducive to the development of operation and maintenance work and the connection between the floating boxes. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide an aisle floating box and a floating box assembly, which can solve the problems in the prior art that the shear force at the connection is large due to different heights of the floating box assembly and it is not conducive to the operation and maintenance work.

[0006] To solve the above technical problems, this application is implemented as follows: In the first aspect, the embodiments of this application provide a floating box assembly, which is arranged on the water surface for photovoltaic power generation on water, including an aisle floating box, a component floating box, and an adjusting mechanism. The aisle floating box and the component floating box are movably connected; the aisle floating box includes a water inlet, one end of the adjusting mechanism is movably connected to the water inlet, and the other end of the adjusting mechanism is movably connected to the component floating box. The adjusting mechanism switches the water inlet between an open state and a closed state according to the height of the aisle floating box on the water surface; when the water inlet is in the open state, water flows into the aisle floating box from the water inlet to change the height of the aisle floating box on the water surface.

[0007] In the embodiments of the present application, both the component floating box and the aisle floating box float on the water surface. The component floating box is arranged to carry the photovoltaic components, and the aisle floating box is arranged to reserve a passage beside the component floating box, facilitating maintenance personnel to pass through for daily maintenance or fault repair of the floating box components. The aisle floating box and the component floating box are movably connected. The aisle floating box includes a water inlet, which is arranged on the side wall where the aisle floating box intersects with the water surface. One end of the adjusting structure is movably connected to the water inlet, and the other end of the adjusting mechanism is movably connected to the component floating box. The adjusting structure can switch the water inlet between the open state and the closed state according to the height of the aisle floating box on the water surface. It can be understood that when the water inlet is in the open state, water flows into the aisle floating box from the water inlet, increasing the weight of the aisle floating box, and then the height of the aisle floating box on the water surface decreases, achieving the purpose of changing the height of the aisle floating box on the water surface. In the embodiments of the present application, through the setting of the adjusting mechanism, water can enter the aisle floating box. Increasing the weight of the aisle floating box can adjust the height of the aisle floating box, reduce the load on the connecting piece between the aisle floating box and the component floating box, enhance the service life of the floating box components, and is beneficial to the development of operation and maintenance and the connection between the floating boxes.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0021] Next, in conjunction with the accompanying drawings, the floating box assembly and floating power station provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0022] In practical applications, due to differences in volume, self-weight, and load conditions between the aisle floating box 10 and the component floating box 20, it is difficult for the height of the aisle floating box 10 to be the same as that of the component floating box 20. Usually, since the component floating box 20 needs to carry photovoltaic components, the height of the aisle floating box 10 on the water surface is generally higher than that of the component floating box 20.

[0023] See Figures 1 to 8, an embodiment of the present application provides a floating box assembly, which is arranged on the water surface for photovoltaic power generation on water, and includes a passage floating box 10, a component floating box 20 and an adjusting mechanism 30. The passage floating box 10 and the component floating box 20 are movably connected; the passage floating box 10 includes a water inlet 11, one end of the adjusting mechanism 30 is movably connected to the water inlet 11, and the other end of the adjusting mechanism 30 is movably connected to the component floating box 20. The adjusting mechanism 30 switches the water inlet 11 between an open state and a closed state according to the height of the passage floating box 10 on the water surface; when the water inlet 11 is in the open state, water flows into the passage floating box 10 from the water inlet 11 to change the height of the passage floating box 10 on the water surface.

[0024] In the embodiment of the present application, both the component floating box 20 and the passage floating box 10 float on the water surface. The component floating box 20 is provided to carry photovoltaic components, and the passage floating box 10 is provided to reserve a passage beside the component floating box 20, facilitating maintenance personnel to pass through for daily maintenance or fault repair of the floating box assembly. The passage floating box 10 and the component floating box 20 are movably connected. The passage floating box 10 includes a water inlet 11, and the water inlet 11 is arranged on the side wall where the passage floating box 10 intersects with the water surface. One end of the adjusting structure is movably connected to the water inlet 11, and the other end of the adjusting mechanism 30 is movably connected to the component floating box 20. The adjusting structure can switch the water inlet 11 between an open state and a closed state according to the height of the passage floating box 10 on the water surface. It can be understood that when the water inlet 11 is in the open state, water flows into the passage floating box 10 from the water inlet 11, the weight of the passage floating box 10 increases, and then the height of the passage floating box 10 on the water surface decreases, achieving the purpose of changing the height of the passage floating box 10 on the water surface. In the embodiment of the present application, through the setting of the adjusting mechanism 30, water can enter the passage floating box 10. Increasing the weight of the passage floating box 10 can adjust the height of the passage floating box 10, reduce the load on the connecting member between the passage floating box 10 and the component floating box 20, enhance the service life of the floating box assembly, and facilitate the operation and maintenance as well as the connection between the floating boxes.

[0025] It should be noted that the passage floating box 10 can be clamped between two component floating boxes 20 to form a space between the two floating boxes, which can provide a standing space for maintenance personnel and is conducive to the development of operation and maintenance work.

[0026] It should also be noted that the material of the passage floating box 10 is ultra-high performance concrete.

[0027] Optionally, in the embodiments of the present application, the adjusting mechanism 30 includes a sliding member 31, an adjusting rod 32, and a baffle 33. The sliding member 31 is movably connected to the component floating box 20. One end of the adjusting rod 32 is movably connected to the sliding member 31, and the other end of the adjusting rod 32 is movably connected to the baffle 33. The baffle 33 is movably connected to the water inlet 11. When the height of the aisle floating box 10 on the water surface is greater than the height of the component floating box 20 on the water surface, the water inlet 11 is in an open state, and water flows into the aisle floating box 10 from the water inlet 11.

[0028] In the embodiments of the present application, the sliding member 31 is movably connected to the component floating box 20. The sliding member 31 is provided to enable the movement of the adjusting structure on the component floating box 20. One end of the adjusting rod 32 is movably connected to the sliding member 31. Driven by the sliding member 31, the adjusting rod 32 moves along with the movement of the sliding member 31 on the component floating box 20. The other end of the adjusting rod 32 is movably connected to the baffle 33, and the baffle 33 is movably connected to the water inlet 11. When the sliding member 31 drives the adjusting rod 32 to move, the adjusting rod 32 can drive the baffle 33 to move. In practical applications, when the height of the aisle floating box 10 on the water surface is greater than the height of the component floating box 20 on the water surface, the adjusting rod 32 drives the baffle 33 to move, so that the water inlet 11 is in an open state, and water flows into the aisle floating box 10 from the water inlet 11. The weight of the aisle floating box 10 increases, and then the height of the aisle floating box 10 on the water surface decreases, achieving the purpose of changing the height of the aisle floating box 10 on the water surface, and making the height of the aisle floating box 10 on the water surface gradually the same as that of the component floating box 20. In the embodiments of the present application, through the settings of the sliding member 31, the adjusting rod 32, and the baffle 33, water can flow into the aisle floating box 10. Increasing the weight of the aisle floating box 10 can adjust the height of the aisle floating box 10, reduce the load on the connecting member between the aisle floating box 10 and the component floating box 20, enhance the service life of the floating box assembly, and facilitate the operation and maintenance as well as the connection between the floating boxes.

[0029] It should be noted that the area of the baffle 33 is at least the same as the area of the water inlet 11, and the area of the baffle 33 can also be larger than the area of the water inlet 11.

[0030] Optionally, in the embodiment of the present application, the adjusting rod 32 includes a first sub-rod 321 and a second sub-rod 322. One end of the first sub-rod 321 is movably connected to the sliding member 31, and the other end of the first sub-rod 321 is fixedly connected to one end of the second sub-rod 322, and the first sub-rod 321 and the second sub-rod 322 are perpendicular to each other. The other end of the second sub-rod 322 is movably connected to the baffle 33; the connection part of the first sub-rod 321 and the second sub-rod 322 is hinged to the aisle floating box 10; during the process that the height of the aisle floating box 10 on the water surface changes from high to low, the water inlet 11 switches from the open state to the closed state, the sliding member 31 moves towards the direction close to the aisle floating box 10, and the second sub-rod 322 rotates around the connection part of the first sub-rod 321 and the second sub-rod 322 to drive the baffle 33 to move towards the direction close to the sliding member 31.

[0031] In the embodiment of the present application, the adjusting rod 32 includes a first sub-rod 321 and a second sub-rod 322. One end of the first sub-rod 321 is movably connected to the sliding member 31. Driven by the sliding member 31, the first sub-rod 321 moves as the sliding member 31 moves on the component floating box 20. The other end of the first sub-rod 321 is fixedly connected to one end of the second sub-rod 322, and the first sub-rod 321 and the second sub-rod 322 are perpendicular to each other. When the first sub-rod 321 moves with the sliding member 31, the first sub-rod 321 drives the second sub-rod 322 to move. The other end of the second sub-rod 322 is movably connected to the baffle 33. When the second sub-rod 322 moves with the first sub-rod 321, the second sub-rod 322 drives the baffle 33 to move so as to switch the water outlet between the open state and the closed state. Wherein, the connection part of the first sub-rod 321 and the second sub-rod 322 is hinged to the side wall where the water inlet 11 is located. During the process that the height of the aisle floating box 10 on the water surface changes from high to low, water flows into the aisle floating box 10 from the water inlet 11, the weight of the aisle floating box 10 increases, the sliding member 31 moves on the component floating box 20, driving the first sub-rod 321 to move towards the direction close to the aisle floating box 10. Driven by the movement of the first sub-rod 321, the second sub-rod 322 rotates around the connection point of the first sub-rod 321 and the second sub-rod 322 as the center of the circle to drive the baffle 33 towards the direction close to the component floating box 20, so that the water outlet gradually switches from the open state to the closed state. In the embodiment of the present application, through the arrangement of the first sub-rod 321 and the second sub-rod 322, water can flow into the aisle floating box 10. Increasing the weight of the aisle floating box 10 can adjust the height of the aisle floating box 10, reduce the load on the connecting piece between the aisle floating box 10 and the component floating box 20, enhance the service life of the floating box assembly, and is beneficial to the operation and maintenance and the connection between the floating boxes. And as the height of the aisle floating box 10 gradually decreases, the baffle 33 is moved to switch the water inlet 11 from the open state to the closed state, preventing too much water from flowing into the aisle floating box 10, and having the beneficial effect of preventing the height of the aisle floating box 10 in the water surface from being lower than that of the component floating box 20.

The aisle floating box 10 includes a first side wall 12, the component floating box 20 includes a second side wall 22. When the component floating box 20 and the aisle floating box 10 are connected to each other, the first side wall 12 and the second side wall 22 are close to and oppositely arranged. Among them, the first connecting member 41 is fixedly connected to the first side wall 12, and the second connecting member 42 is fixedly connected to the second side wall 22. When the first connecting member 41 and the second connecting member 42 are connected to each other, the connection between the component floating box 20 and the aisle floating box 10 is realized.

[0041] In the embodiment of the present application, the second connecting portion 422 is cylindrical and perpendicular to the water surface, and a limiting portion is provided at one end of the second connecting portion 422 close to the water surface. In practical applications, the first connecting portion 412 is sleeved around the second connecting portion 422 and is restricted by the limiting portion from moving downward in the direction perpendicular to the water surface. The setting of the second connecting portion 422 enables the connection between the aisle floating box 10 and the component floating box 20 to have almost no load in the vertical direction. The first connecting member 41 only exerts a force on the second connecting member 42 in the horizontal direction to limit the position between the first connecting member 41 and the second connecting member 42, which has the beneficial effect of making the operation and maintenance passage more stable in terms of force. In addition, the setting of the limiting portion has the beneficial effect of preventing the aisle floating box 10 from taking in too much water and causing the first connecting member 41 to fall off from one end of the second connecting member 42 close to the water surface, and preventing the aisle floating box 10 and the component floating box 20 from separating from each other.

The aisle floating box 10 includes a second surface 13, the second surface 13 is parallel to and faces away from the water surface, and the second surface 13 includes ventilation holes 131 which are in communication with the interior of the aisle floating box 10.

[0043] In the embodiments of the present application, the aisle floating box 10 is a frustum with a hollow interior. The setting of the hollow frustum enables the water flowing in from the water inlet hole to be stored in the aisle floating box 10, thereby adjusting the height of the floating box in the water surface. The aisle floating box 10 includes a second surface 13 parallel to and facing away from the water surface, and the ventilation holes 131 are provided on the second surface 13. The setting of the ventilation holes 131 allows air to flow inside the aisle floating box 10, so that the water inlet 11 has no obstruction for water inlet, and it can also serve as an evaporation channel for the moisture inside the aisle floating box 10, and can also slowly reduce the self-weight of the aisle floating box 10.

[0044] It should be noted that the frustum can be a structure with a larger upper part and a smaller lower part. The frustum-shaped aisle floating box 10 with a larger upper part and a smaller lower part has the beneficial effect of being convenient for installation.

[0045] It should also be noted that the ventilation holes 131 can be round holes, square holes, or irregular holes, and the present embodiment does not make any restrictions on this.

[0046] It should further be noted that a grid plate can be provided above the ventilation holes 131. The area of the grid plate is at least the same as the area of the ventilation holes 131, or can be larger than the area of the ventilation holes 131. The setting of the grid plate has the beneficial effect of preventing maintenance personnel from getting injured due to stepping into the void when walking on the floating box.

[0047] Optionally, in the embodiments of the present application, a floating power station is provided, including the floating box assembly as described above.

One end of the adjusting structure is movably connected to the water inlet 11, and the other end of the adjusting mechanism 30 is movably connected to the component floating box 20. The adjusting structure can switch the water inlet 11 between the open state and the closed state according to the height of the aisle floating box 10 on the water surface. It can be understood that when the water inlet 11 is in the open state, water flows into the aisle floating box 10 from the water inlet 11, increasing the weight of the aisle floating box 10, and thus reducing the height of the aisle floating box 10 on the water surface, achieving the purpose of changing the height of the aisle floating box 10 on the water surface. In the embodiment of the present application, through the setting of the adjusting mechanism 30, water can enter the aisle floating box 10. Increasing the weight of the aisle floating box 10 can adjust the height of the aisle floating box 10, reduce the load on the connecting member between the aisle floating box 10 and the component floating box 20, enhance the service life of the floating box assembly, and is beneficial to the development of operation and maintenance and the connection between floating boxes in the floating power station.
