Technical Field
[0001] This application relates to the field of photovoltaic equipment, and in particular, to a floating photovoltaic bracket with adjustable pitching angle. Background Art
[0002] Photovoltaic power generation is a green power generation form actively advocated today, and it usually uses solar panels to generate electricity.
[0003] Using solar panels to generate electricity requires a large area, and it is mostly suitable to build large-scale photovoltaic power stations in desert areas. Nowadays, there are also some technologies for building large-scale photovoltaic power stations on open waters such as lakes and reservoirs.
[0004] In the prior art, solar panels are mostly fixedly connected to floating platforms on water, and the pitching angle of the solar panels cannot be changed. Therefore, it is difficult for the solar panels to maintain an efficient power generation state.
[0005] In view of this, a floating photovoltaic bracket with adjustable pitching angle is needed. Utility Model Content
[0006] In order to improve the problem that the pitching angle of the solar panel cannot be changed and it is difficult to maintain an efficient power generation state, this application provides a floating photovoltaic bracket with adjustable pitching angle.
[0007] A floating photovoltaic bracket with adjustable pitching angle provided by this application adopts the following technical solution: A floating photovoltaic bracket with adjustable pitching angle includes a floating component, a bracket component, and a pump set. The bracket component is adapted to be connected to a solar panel, and the solar panel can be connected to the floating component via the bracket component;
[0008] The floating component includes a main frame and movable floating units. The bracket component includes a fixed bracket and adjusting support rods. The fixed bracket is connected to the solar panel. A plurality of the adjusting support rods and the movable floating units are provided. One end of each adjusting support rod is rotatably connected to the fixed bracket, and the other end of each adjusting support rod is fixedly connected to the corresponding movable floating unit. The movable floating units can move on the main frame, and the pump set is connected to the movable floating units to be able to pump water into the movable floating units or pump water out of the movable floating units.
[0009] By adopting the above technical solution, it is possible to adjust the floating and sinking of each floating unit by pumping water into or out of the moving floating unit, so that when the moving floating unit floats, it can drive the position on the solar panel corresponding to the moving floating unit to rise, and when the moving floating unit sinks, it can drive the position on the solar panel corresponding to the moving floating unit to sink, thereby enabling the adjustment of the pitching angle of the solar panel, so that the solar panel can always be perpendicular to the sunlight and maintain an efficient power generation state all the time.
[0010] Further, the fixed bracket is a rectangular frame with a size matching that of the solar panel, and each of the four top corners of the fixed bracket is connected with one of the adjusting support rods, and the adjusting support rods are connected to the fixed bracket via ball head bearings.
[0011] By adopting the above technical solution, it is possible to adjust the pitching angles of the solar panel in two perpendicular directions, so that it can not only adapt to the change of sunlight angle during the change of seasons, but also enable the solar panel to follow the sunlight and change its orientation from morning to evening.
[0012] Further, the main body frame includes four long strip-shaped fixed floating blocks and a pair of moving floating blocks. The four fixed floating blocks are connected end to end to form the rectangular main body frame. A first-direction limiting groove extending along the length direction of the fixed floating block is provided on a pair of relatively arranged fixed floating blocks. Both ends of the moving floating block are respectively connected with one of the fixed floating blocks provided with the first-direction limiting groove, and the moving floating block can move along the first-direction limiting groove. A second-direction limiting groove is further provided on the moving floating block, and the extending direction of the second-direction limiting groove is perpendicular to the extending direction of the first-direction limiting groove.
[0013] By adopting the above technical solution, when the pitching angle of the solar panel changes, the moving floating units will also approach or move away from each other. The setting of the first-direction limiting groove and the second-direction limiting groove can limit the movement of the moving floating units, thereby preventing the situation that the solar panel moves randomly on the water surface during the process of adjusting the pitching angle and causes adjacent solar panels to collide.
[0014] Further, the moving floating unit includes a water storage part and a support part. One end of the support part is connected with the water storage part, and the other end of the support part can pass through the second-direction limiting groove and be connected with the adjusting support rod; an air duct is provided on the support part, and a water storage cavity is formed in the water storage part, and the water storage cavity is communicated with the atmosphere via the air duct.
[0015] By adopting the above technical solution, it is convenient to realize sinking by injecting water and floating by draining water.
[0016] Further, an abutting ring is also provided on the supporting part so as to be able to abut against the moving floating block via one side of the abutting ring facing the water storage part.
[0017] By adopting the above technical solution, when the water storage part loses buoyancy due to the breakage of the water storage cavity, the moving floating block can be abutted by the abutting ring, and then the main frame can bear the weight of the solar panel, effectively preventing the solar panel from sinking into the water.
[0018] Further, the pump group includes a plurality of bidirectional gear pumps, and the water storage parts of the moving floating units are connected to the corresponding bidirectional gear pumps via water conveyance pipelines.
[0019] By adopting the above technical solution, using bidirectional gear pumps can reduce the amount of water pumps on the premise of realizing pumping water into the moving floating unit or pumping water out of the moving floating unit.
[0020] Further, the bracket assembly further includes a positioning bracket, the positioning bracket is connected to the middle part of the fixed bracket via the ball head bearing, and the positioning bracket is also fixedly connected to the main frame.
[0021] By adopting the above technical solution, the main frame can bear most or all of the weight of the solar panel, so that the size of the moving floating unit can be smaller.
[0022] Further, a controller is also included. A photosensitive sensor is provided on one side facing the water surface at each edge of the solar panel, and each photosensitive sensor is communicatively connected to the controller to transmit light intensity information to the controller. The controller is also communicatively connected to the bidirectional gear pump, and the controller is configured to be able to control the water pumping direction of the bidirectional gear pump via the light intensity information.
[0023] By adopting the above technical solution, it is possible to judge whether the solar panel is perpendicular to the sunlight by the difference in the intensity of the light detected by the photosensitive sensors on a pair of relatively arranged edges, so as to facilitate the adjustment of the pitch of the solar panel.
[0024] In summary, the present application includes at least one of the following beneficial effects:
[0025] It is possible to adjust the floating and sinking of each floating unit by pumping water into the floating unit or pumping water out of the moving floating unit, so that when the moving floating unit floats, it can drive the corresponding position on the solar panel to rise, and when the moving floating unit sinks, it can drive the corresponding position on the solar panel to sink, thereby realizing the adjustment of the pitch angle of the solar panel, so that the solar panel can always be perpendicular to the sunlight and maintain an efficient power generation state all the time.

[0032] Figure 1 is a perspective view of a floating photovoltaic support with adjustable pitching angle according to the present application, Figure 2 is a top view of a floating photovoltaic support with adjustable pitching angle according to the present application. Referring to Figure 1 and Figure 2 a floating photovoltaic support with adjustable pitching angle provided by the present application includes a floating assembly 1, a support assembly 2 and a pump set. The support assembly 2 is adapted to be connected to a solar panel 3, and the solar panel 3 can be connected to the floating assembly 1 via the support assembly 2.
[0033] Specifically, the floating assembly 1 includes a main frame 11 and a dynamic floating unit 12, the bracket assembly 2 includes a fixed bracket 21 and an adjusting support rod 22, the fixed bracket 21 is connected to the solar panel 3, the adjusting support rod 22 and the dynamic floating unit 12 are both provided in plurality, one end of each adjusting support rod 22 can be rotatably connected to the fixed bracket 21, and the other end of each adjusting support rod 22 is fixedly connected to the corresponding dynamic floating unit 12, the dynamic floating unit 12 can be moved on the main frame 11, and the pump group is connected to the dynamic floating unit 12 so as to be able to pump water into the dynamic floating unit 12 or pump water out of the dynamic floating unit 12 to control the buoyancy of each dynamic floating unit 12, so that when the dynamic floating unit 12 floats, the position corresponding to the dynamic floating unit 12 on the solar panel 3 can be driven to rise, and when the dynamic floating unit 12 sinks, the position corresponding to the dynamic floating unit 12 on the solar panel 3 can be driven to sink, thereby realizing the adjustment of the pitch angle of the solar panel 3, so that the solar panel 3 can always be perpendicular to the sunlight to always maintain an efficient power generation state.
[0034] Figure 3 yes Figure 2 Sectional view along the AA direction, Figure 4 yes Figure 3 Enlarged view of area B, see Figure 3 and Figure 4 Taking the solar panel 3 as a rectangle as an example, the fixed bracket 21 is a rectangular frame with a size matching the solar panel 3, and an adjusting support rod 22 is connected to each of the four top corners of the fixed bracket 21, and the adjusting support rod 22 is connected to the fixed bracket 21 via a ball bearing, so that during the floating and sinking process of the dynamic floating unit 12, the adjusting support rod 22 and the fixed bracket 21 can rotate relative to each other, thereby facilitating the pitch adjustment of the solar panel 3, and ensuring that the dynamic floating unit 12 is in a vertical state during the pitch adjustment of the solar panel 3, and it is not easy for the dynamic floating unit 12 to tilt and cause an unstable center of gravity, which can improve the overall stability.
[0035] remember Figure 1Taking the upper left corner of the middle fixed bracket 21 as A, the upper right corner as B, the lower right corner as C, and the lower left corner as D, and taking the example that the two corners C and D face south towards the sun, when the moving floating units 12 corresponding to the two corners A and B float synchronously while the moving floating units 12 corresponding to the two corners C and D sink synchronously, it can make the side of the solar panel 3 facing north stand up (that is, the vertical height difference from the side of the solar panel 3 facing south increases), so that the solar panel 3 can be perpendicular to the sunlight in winter; when the moving floating units 12 corresponding to the two corners A and B sink synchronously while the moving floating units 12 corresponding to the two corners C and D float synchronously, it can make the vertical height difference between the side of the solar panel 3 facing north and the side of the solar panel 3 facing south decrease, so that the solar panel 3 can be perpendicular to the sunlight in summer. In addition, on the basis of the above, the moving floating units 12 corresponding to the two corners B and C can sink synchronously while the moving floating units 12 corresponding to the two corners A and D rise synchronously, so that the solar panel 3 faces east, and the moving floating units 12 corresponding to the two corners B and C can float synchronously while the moving floating units 12 corresponding to the two corners A and D sink synchronously, so that the solar panel 3 faces west, so that the solar panel 3 can follow the sunlight and change its orientation from morning to evening.
[0036] See Figure 1 and Figure 2 , the main body frame 11 includes four long strip-shaped fixed floating blocks 111 and a pair of moving floating blocks 112. The four fixed floating blocks 111 are connected end to end to form a rectangular main body frame 11. A first-direction limiting groove 1111 extending along the length direction of the fixed floating block 111 is provided on a pair of relatively arranged fixed floating blocks 111. Both ends of the moving floating block 112 are connected to a fixed floating block 111 provided with a first-direction limiting groove 1111, and the moving floating block 112 can move along the first-direction limiting groove 1111. A second-direction limiting groove 1121 is further provided on the moving floating block 112. The extending direction of the second-direction limiting groove 1121 is perpendicular to the extending direction of the first-direction limiting groove 1111. When the pitching angle of the solar panel 3 changes, the moving floating units 12 will also approach or move away from each other. The setting of the first-direction limiting groove 1111 and the second-direction limiting groove 1121 can limit the movement of the moving floating units 12, so as to prevent the situation that the solar panel 3 moves randomly on the water surface during the process of adjusting the pitching angle and causes the adjacent solar panels 3 to collide.
[0037] Figure 5 is Figure 3 The enlarged view of area C in, see Figure 3 and Figure 5, the movable floating unit 12 includes a water storage part 121 and a support part 122. One end of the support part 122 is connected to the water storage part 121, and the other end of the support part 122 can pass through the second-direction limiting groove 1121 to be connected to the adjusting rod 22; an air duct 1221 is provided on the support part 122, and an air port is formed at one end of the air duct 1221 on the support part 122 away from the water storage part 121. A water storage cavity is formed in the water storage part 121, and the water storage cavity is communicated with the atmosphere through the air duct 1221. The setting of the air duct 1221 can facilitate the water injection and sinking as well as the drainage and floating of the movable floating unit 12. It should be noted that the water storage part 121 should also be provided with a watertight cabin that wraps the water storage cavity.
[0038] See Figure 3 and Figure 4 , a contact ring 1222 is also provided on the support part 122, so that it can be in contact with the moving floating block 112 through the side of the contact ring 1222 facing the water storage part 121. When the water storage cavity is damaged and the water storage part 121 loses buoyancy, the moving floating block 112 can be in contact with the contact ring 1222, and then the main body frame 11 can bear the weight of the solar panel 3, effectively preventing the solar panel 3 from sinking into the water.
[0039] The pump set can be set to include a plurality of two-way gear pumps (not shown in the figure). The water storage part 121 of each movable floating unit 12 is connected to the corresponding two-way gear pump through a water delivery pipeline. Using a two-way gear pump can reduce the amount of water pumps on the premise of realizing pumping water into the movable floating unit 12 or pumping water out of the movable floating unit 12.
[0040] In addition, it can be understood that in order to increase the power generation, in actual use, it is necessary to deploy solar panels 3 on a large scale on the water surface. According to the above scheme, four movable floating units 12 need to be correspondingly set for each solar panel 3. For example, if every ten solar panels 3 are arranged in a row, forty movable floating units 12 are required. These forty movable floating units 12 can be divided into four groups according to the connection correspondence with the fixed bracket 21, that is, they are respectively divided into a group corresponding to the upper left corner, upper right corner, lower right corner, and lower left corner of the fixed bracket 21, and each group of ten movable floating units 12 is connected to a two-way gear pump, so that the amount of water pumps is less and the cost is lower.
[0041] See Figure 1 and Figure 3 , the bracket assembly 2 further includes a positioning bracket 23. The positioning bracket 23 is connected to the middle part of the fixed bracket 21 through a ball head bearing, and the positioning bracket 23 is also fixedly connected to the main body frame 11, so that the main body frame 11 can bear most or all of the weight of the solar panel 3, so that the size of the movable floating unit 12 can be relatively small.
[0042] See Figure 1and Figure 2 Moreover, the floating photovoltaic bracket with adjustable pitch angle of the present application further includes a controller (not shown in the figure). A photosensitive sensor 4 is provided on the side facing the water surface at each edge of the solar panel 3. Each photosensitive sensor 4 is communicatively connected to the controller to transmit light intensity information to the controller. The controller is also communicatively connected to the two-way gear pump, and the controller is configured to be able to control the water pumping direction of the two-way gear pump via the light intensity information. Specifically, the controller can judge whether the solar panel 3 is perpendicular to the sunlight by the difference in the intensity of the light detected by the photosensitive sensors 4 on a pair of relatively arranged edges. For example, if the light intensity detected by the photosensitive sensor 4 on the east side is less than the light intensity detected by the photosensitive sensor 4 on the west side, it means that the orientation of the solar panel 3 needs to be adjusted westward until the light intensities detected by the photosensitive sensors 4 on the east and west sides are the same.
[0043] The working principle of the floating photovoltaic bracket with adjustable pitch angle of the present application is as follows:
[0044] It is possible to adjust the floating and sinking of each floating unit by pumping water into the floating unit or pumping water out of the floating unit 12, so that when the floating unit 12 floats, it can drive the corresponding position on the solar panel 3 to rise, and when the floating unit 12 sinks, it can drive the corresponding position on the solar panel 3 to sink, thereby enabling the adjustment of the pitch angle of the solar panel 3, so that the solar panel 3 can always be perpendicular to the sunlight and maintain an efficient power generation state all the time.
[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
