Description

Technical Field

[0001] This utility model relates to the technical field of solar-fishery complementary photovoltaic support structures, and in particular to an installation structure for such support structures. Background Technology

[0002] The solar-aquaculture hybrid photovoltaic (PAC) support structure is a special support structure used in solar-aquaculture hybrid power generation projects. It's an innovative support system that combines photovoltaic power generation with aquaculture. By erecting a photovoltaic support structure above fishponds, lakes, or other bodies of water and installing solar photovoltaic panels, it achieves the dual benefits of photovoltaic power generation and aquaculture. It features high land resource utilization, fully utilizing water space for power generation without occupying additional land, realizing a three-dimensional integrated utilization of "power generation above, fish farming below." Simultaneously, the photovoltaic panels can provide some shading for aquaculture, helping to regulate water temperature and improve the aquaculture environment.

[0003] A search revealed Chinese patent CN 222321414 U, which discloses a photovoltaic support structure for a fishery-solar hybrid system. The structure includes multiple precast cement columns and longitudinal support components fixedly mounted on each precast cement column. The longitudinal support components are fixedly connected to the precast cement columns via clamp components. Transverse support components connect the multiple longitudinal support components. Photovoltaic panels are fixedly mounted on the transverse support components. The longitudinal support components are located at the top of the precast cement columns, and the longitudinal support components on adjacent precast cement columns are parallel to each other. This photovoltaic support structure, through the joint support of the longitudinal support components on multiple columns to the transverse support components, improves the overall stability of the support structure and thus enhances the structural strength of the photovoltaic system.

[0004] Regarding the aforementioned technologies, the inventors have found the following shortcomings: Since the use environment of the solar-fishery complementary photovoltaic support structure is deep water, it is difficult to ensure the stable use of the solar-fishery complementary photovoltaic panels by using ordinary supports, and they are not convenient to install. They cannot automatically adjust the height according to changes in water level, cannot adapt to more water areas, and have poor stability under the impact of wind and waves. Utility Model Content

[0015] 1. This utility model allows the photovoltaic panel support for fishery-solar integration to float on the water surface under the action of the buoy. It is flexible in installation, does not require the use of too many cement poles or other components, is easy to move, can adapt to more water areas, and is less affected by the water area. Under the buoyancy of the buoy and the central buoyancy plate, it can support a large number of photovoltaic panels.

[0016] 2. This utility model uses anchor chains to fix the buoy to the bottom of the water. The tension of the anchor chains can balance the horizontal force generated by the water flow and wind, preventing the buoy and the solar-powered fishery from drifting. By setting up a guide plate, the direction of the water flow is changed, reducing the impact of the water flow on the object, so that the solar panel can remain stationary in the horizontal direction.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0023] This utility model discloses an installation structure for a photovoltaic support bracket that integrates fisheries and solar power. For example... Figure 1 As shown, it includes a bottom support frame 1, which is set in a "C" shape. There are two "C" shaped bottom support frames 1. The "C" shaped bottom support frames 1 make it easier to install photovoltaic panels. A top photovoltaic panel 2 is fixedly installed on the top of the two bottom support frames 1. Fixing holes are provided at both the upper and lower ends of the bottom support frame 1 to fix the photovoltaic panel.

[0024] Please see Figure 2The bottom of the bottom support frame 1 is fixed with a central buoyancy plate 10 by bolts. Two identical sliding plates 9 are set in the middle of the left and right sides of the central buoyancy plate 10. The sliding plates 9 are set in an upward arc shape. The upward arc shape of the sliding plates 9 can buffer and resist the flowing waves and reduce the impact of the waves on the support. The bottom of the left and right sides of the central buoyancy plate 10 is fixed with a guide plate 4 by a connecting shaft. The guide plate 4 is set in a figure-eight shape. The figure-eight-shaped guide plate 4 can guide the water flow in a specific direction to avoid the water flow directly impacting the photovoltaic frame. By dispersing and guiding the water flow, the impact force of the water flow is dispersed to a larger area, thereby reducing the local impact force on the photovoltaic panel.

[0025] Please see Figure 2 and Figure 3 The middle buoyancy plate 10 has floats 3 fixed at both ends of the middle buoyancy plate 10 by horizontal plates. The diameter of the floats 3 is larger than the thickness of the middle buoyancy plate 10. The bottom power box 8 is fixed at the bottom of the middle buoyancy plate 10. The rotating shaft 19 is rotatably installed in the middle of the inner wall of the bottom power box 8. The two ends of the rotating shaft 19 are rotatably installed with transverse fixing plates 18. The end of the transverse fixing plate 18 away from the rotating shaft 19 is fixed to one side of the inner wall of the bottom power box 8. The transverse fixing plate 18 supports the rotating shaft 19 to ensure that the rotating shaft 19 can rotate better. The end of the rotating shaft 19 away from the ratchet 11 extends to the outside of the bottom power box 8. The rotation of the rotating shaft 19 facilitates the retraction of the anchor chain 5.

[0026] Please see Figure 3 A rotating roller 17 is fixedly sleeved in the middle of the rotating shaft 19. An anchor chain 5 is fixedly installed in the middle of the rotating roller 17. An anchor rod 6 is fixedly installed at the bottom of the anchor chain 5. An anchor claw 7 is rotatably installed at the bottom of the anchor rod 6 through the anchor shackle. The bottom of the anchor claw 7 is designed as a ring. The top edge of the ring at the bottom of the anchor claw 7 is beveled. Three sets of crossbars are set in the middle of the ring at the bottom of the anchor claw 7. The outer side of the crossbars is beveled. The anchor claw 7 can grip the mud, sand or rock when the anchor sinks to the bottom of the water, providing strong gripping force so that the photovoltaic frame can be stably moored.

[0027] Please refer to it again. Figure 2 and Figure 3A ratchet 11 is fixedly sleeved at the front end of the rotating shaft 19. The ratchet 11 is engaged with an arc-shaped limiting plate 13 through teeth on one side of its circumferential surface. A support plate 16 is rotatably mounted on the middle of the arc-shaped limiting plate 13 via a rotating shaft. The top of the support plate 16 is fixedly mounted on the top of the inner wall of the bottom power box 8. The support plate 16 acts as a fulcrum for the arc-shaped limiting plate 13, enabling the arc-shaped limiting plate 13 to rotate effectively. A movable vertical plate 14 is slidably sleeved at the end of the arc-shaped limiting plate 13 away from the ratchet 11. A groove is provided in the middle of the movable vertical plate 14. The groove is located on the outer side of one end of the arc-shaped limiting plate 13. One end of the arc-shaped limiting plate 13 swings under the action of the ratchet 11. The bottom of the movable vertical plate 14 is slidably connected to the limiting vertical rod 12. A spring is sleeved on the outside of the limiting vertical rod 12. The top of the spring is fixed to the bottom of the movable vertical plate 14 through a pad. When the movable vertical plate 14 moves downward under the action of the pressing rod 15, it presses one end of the arc-shaped limiting plate 13 downward, so that the other end of the arc-shaped limiting plate 13 is released from the ratchet 11. The top of the movable vertical plate 14 is fixedly provided with the pressing rod 15, and the top of the pressing rod 15 extends to the upper surface of the middle buoyancy plate 10.

[0028] The implementation principle of the photovoltaic bracket installation structure for fishery-solar hybrid in this embodiment of the utility model is as follows: In use, the fishery-solar hybrid photovoltaic system is fixed above the bottom support frame 1. The float 3 and the lower middle buoyancy plate 10 are moved to the water surface. The anchor claw 7 is placed in the water via the anchor chain 5. When the anchor claw 7 sinks to the bottom, it grips the mud, sand, or rocks, providing strong gripping force so that the float 3 above can be stably moored. The anchor chain 5 is driven by gravity to rotate the rotating roller 17 and the rotating shaft 19, while the ratchet 11 rotates in one direction. When the ratchet 11 rotates, one end of the arc-shaped limiting plate 13 above it jumps. When the ratchet 11 is stationary, one end of the arc-shaped limiting plate 13 engages with the teeth on the surface of the ratchet 11 to prevent the ratchet 11 from moving excessively and keep the anchor chain 5 in a taut state. When it is necessary to retract the anchor claw 7, press the pressing rod 15 down to make the moving vertical plate 14 move one end of the arc-shaped limiting plate 13 downward, and the other end of the arc-shaped limiting plate 13 moves upward and disengages from the ratchet 11. The anchor chain 5 can be retracted by rotating it on the outside relative to the rotating shaft 19.

[0029] The guide plates 4 on the left and right sides of the central buoyancy plate 10 can guide the water flow in a specific direction, avoiding direct impact of the water flow on the photovoltaic frame. By dispersing and guiding the water flow, the impact force of the water flow is dispersed over a larger area, thereby reducing the local impact force on the photovoltaic panel.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
