Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic devices, and particularly relates to a buoy-type photovoltaic device and a using method thereof. Background Art

[0002] A buoy-type photovoltaic device, which is generally more widely known as a floating photovoltaic system, is an innovative way of photovoltaic power generation. It uses the water surface as an installation platform, and floats photovoltaic modules on the water surface for power generation. The buoy-type photovoltaic device mainly consists of photovoltaic panels, buoys and anchor ropes. The buoys are installed on both sides of the floating board and fixed by the anchor ropes. The buoys can float the photovoltaic panels on the water surface to achieve photovoltaic power generation on the water surface.

[0003] Conventional photovoltaic panels are mainly installed between brackets and buoys, usually at a fixed angle and installed on the water surface. Although there is no obstruction on the water surface, within a day, the change of the illumination angle will also cause the photovoltaic panels on the water surface to not reach the optimal illumination angle, resulting in a decrease in the photovoltaic power generation efficiency and affecting the power generation amount.

[0004] At the same time, the photovoltaic panels installed on the water surface have basically no obstruction around them. In sunny weather, a certain amount of dust will adhere to the photovoltaic panels. Since the installation position of the photovoltaic panels is generally far from the shore, it is very inconvenient to clean. Usually, operators regularly take boats to wash the surface of the photovoltaic panels, and the overall cleaning efficiency is low, which urgently needs to be improved. Summary of the Invention

[0007] During normal use, the inside of the buoy is filled with air to ensure that the device floats on the water surface. When the photovoltaic panel is in normal use, there is a certain angle between it and the frame to ensure correct sunlight reception. At the same time, the water pump is connected to an external power supply, and an external cable is fixed to the buoy to ensure that the device does not float with the water flow.

[0008] As a further technical solution of the present invention, the adjusting component includes an oil storage pipe, the outer side of the oil storage pipe is fixedly sleeved with the first locking frame, a drain pipe is fixedly communicated with the front end of the oil storage pipe, and the front end of the drain pipe is communicated with the bottom end of the temporary storage box.

[0009] As a further technical solution of the present invention, a water injection valve is fixedly communicated with the position near the bottom end of the rear side of the oil storage pipe, the other end of the water injection valve is communicated with the water delivery pipe, a piston plate is movably sleeved inside the oil storage pipe, and hydraulic oil is filled between the front end of the piston plate and the front end of the inner cavity of the oil storage pipe.

[0010] As a further technical solution of the present invention, piston rods are fixedly connected to the ends of the piston plate away from the piston plate, a limiting spring is movably sleeved on the outer side of the piston rod, and the front and rear ends of the limiting spring are connected to one end of the piston plate and one end of the inner cavity of the oil storage pipe.

[0011] As a further technical solution of the present invention, one end of the piston rod far from the piston plate penetrates through one side of the oil storage pipe and is fixedly connected with a second fixed seat.

One ends of the connecting rods far from the second fixed seats are all movably connected with first fixed seats through rotating shafts. The top ends of the first fixed seats are connected to the positions near the front side of the bottom end of the photovoltaic panel.

[0013] When it is necessary to adjust the tilt angle of the photovoltaic panel to ensure correct sunlight reception, that is, when the sun is directly above, the water pump can be turned on to suck water through the three-way valve. After suction, the water flow can enter the interior of the three-way valve and enter the interior of the injection valve through two water pipes. At this time, the water flow can enter the interior of the oil storage pipe and apply pressure to the piston plate. At this time, the piston plate moves forward, and the limit spring is stretched, pulling the guide block forward. At this time, the guide block moves relative to the extension guide rail, and the connecting rod deflects obliquely downward, applying a pulling force to the first fixed seat. At this time, the photovoltaic panel rotates obliquely downward until the photovoltaic panel is parallel to the frame, completing the angle adjustment process.

[0014] By directly sucking the clear water inside the water body by using the water pump and through the cooperation between the adjustment component and the photovoltaic panel, the device can actively adjust the tilt angle of the photovoltaic panel without shutting down. The whole process can be automatically completed, and only by controlling the water flow rate entering the adjustment component can the precise adjustment of the tilt angle of the photovoltaic panel be realized, matching the optimal sunlight angle and improving the power generation efficiency.

[0015] As a further technical solution of the present invention, the power component includes a water storage pipe. The outer side surface of the water storage pipe is fixedly sleeved with a second locking frame. The front end of the water storage pipe is fixedly communicated with an elbow pipe, and the other end of the elbow pipe is fixedly communicated with a temporary storage box. A return spring is movably sleeved on the outer side surface of the limit rod, and the front and rear ends of the return spring are connected to one end of the limit plate and one end of the inner cavity of the water storage pipe.

[0016] As a further technical solution of the present invention, one end of the limit rod far from the limit plate penetrates through one end of the water storage pipe and is fixedly connected with a magnetic attraction plate.

[0017] And when the piston plate moves forward, the hydraulic oil in the oil storage pipe can be pressed out through the drain pipe and enter the interior of the temporary storage box through the drain pipe for temporary storage.

[0018] When the photovoltaic panel is parallel to the frame, the front side of the photovoltaic panel is then located below the water surface. At this time, the surface of the photovoltaic panel can be assisted in cleaning through the flow of clear water to complete the preliminary cleaning process.

[0019] By utilizing the angle adjustment process of the photovoltaic panel, that is, when the photovoltaic panel is adjusted to be parallel to the frame, the front side of the photovoltaic panel can be kept below the water surface at this time, and self-cleaning is achieved through the flow of water, so that the photovoltaic panel can be self-cleaned every time it is adjusted to a specific angle. The whole process is automatically completed, avoiding the use of manual assisted cleaning methods, improving the surface cleanliness of the photovoltaic panel, and thus improving the power generation efficiency.

[0020] As a further technical solution of the present invention, the auxiliary cleaning component includes a limit guide rail, the limit guide rail is connected to the front side of the photovoltaic panel, a limit block is movably clamped inside the limit guide rail, a cleaning brush is fixedly installed in the middle of the limit block, and when the photovoltaic panel is parallel to the frame, the magnetic attraction plate is located on one side of the cleaning brush and is magnetically connected to the cleaning brush.

[0021] At the same time, when the photovoltaic panel is parallel to the frame and deep cleaning of the surface of the photovoltaic panel is required, the oil pump inside the temporary storage box can be started, and then the hydraulic oil can be led out through the elbow pipe and enter the inside of the water storage pipe, and a thrust is applied to the limit plate. At this time, the limit plate and the limit rod move backward, and the return spring is stretched. At this time, the magnetic attraction plate moves toward the cleaning brush until it is magnetically adsorbed to it. As the magnetic attraction plate continues to move, the cleaning brush can be driven to wipe and clean the surface of the photovoltaic panel to complete the deep cleaning process.

[0022] By utilizing the adjustment process of the tilt angle of the photovoltaic panel, the adjusted auxiliary cleaning component corresponds to the power component. At the same time, by using the cooperation between the adjustment component, the temporary storage box and the power component, through the transfer of hydraulic oil and in cooperation with the angle change of the auxiliary cleaning component, self-cleaning of the surface of the photovoltaic panel is realized. The whole process is still automatically completed, and an automatic and regular deep cleaning process can be realized, improving the cleaning efficiency and thus improving the overall power generation efficiency.

[0023] A usage method of a buoy type photovoltaic device includes the following steps:

[0024] S1: When the device is in normal use, the buoy can be kept filled with air, the whole device is floated on the water surface, fixed by an external cable at the same time, and the power supply of the water pump is connected to complete the preparation work;

[0025] S2: When it is necessary to adjust the tilt angle of the photovoltaic panel and adjust it in the direction of laying flat, the water pump can be turned on to suck water flow into the inside of the three-way valve and input it into the inside of the oil storage pipe through the water delivery pipe. At this time, the piston plate moves forward accordingly, and the guide block is pulled to move to the left. At this time, the connecting rod deflects accordingly and applies a downward pulling force to the photovoltaic panel. At this time, the photovoltaic panel rotates relative to the mounting shaft until it turns into a flat laying state;

[0026] S3: At this time, the photovoltaic panel comes into contact with the water body. When the piston plate moves forward, the hydraulic oil can be introduced into the inside of the temporary storage tank. At this time, turning on the oil pump inside the temporary storage tank can introduce the hydraulic oil into the inside of the water storage pipe. At this time, the limit plate moves backward accordingly, and drives the magnetic attraction plate to move backward;

[0027] S4: When the magnetic attraction plate and the cleaning brush adsorb each other, the cleaning brush can be driven to displace relative to the limit guide rail and actively clean the surface of the photovoltaic panel, completing the self-cleaning process.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) By directly sucking the clear water inside the water body by using the water pump and through the cooperation between the adjustment component and the photovoltaic panel, the device can actively adjust the tilt angle of the photovoltaic panel without shutting down. The whole process can be automatically completed, and only by controlling the water flow rate entering the adjustment component can the precise adjustment of the tilt angle of the photovoltaic panel be realized, matching the best illumination angle and improving the power generation efficiency.

[0030] (2) By using the process of adjusting the angle of the photovoltaic panel, that is, when the photovoltaic panel is adjusted to be parallel to the frame, at this time, the front surface of the photovoltaic panel can be kept below the water surface, and self-cleaning is realized through the flow of water, so that the photovoltaic panel can be self-cleaned every time it is adjusted to a specific angle. The whole process is automatically completed, avoiding the use of manual auxiliary cleaning methods, improving the surface cleanliness of the photovoltaic panel, and thus improving the power generation efficiency.

[0031] (3) By using the process of adjusting the tilt angle of the photovoltaic panel, the adjusted auxiliary cleaning component corresponds to the power component. At the same time, through the cooperation between the adjustment component, the temporary storage tank and the power component, through the transfer of hydraulic oil and in cooperation with the angle change of the auxiliary cleaning component, the self-cleaning of the surface of the photovoltaic panel is realized. The whole process is still automatically completed, and the automatic and regular in-depth cleaning process can be realized, improving the cleaning efficiency, and thus improving the overall power generation efficiency.

[0043] During normal use, the inside of the buoy 7 is filled with air to ensure that the device floats on the water surface. When the photovoltaic panel 4 is in normal use, there is a certain angle between it and the frame 1 to ensure correct light reception. At the same time, the water pump 10 is connected to an external power source, and an external cable is fixed to the buoy 7 to ensure that the device does not float with the water flow.

[0044] Such as Figure 1 and Figure 4 as well as Figure 6As shown in the figure, the adjusting assembly 8 includes an oil storage pipe 805. The outer side surface of the oil storage pipe 805 is fixedly sleeved with the first locking frame 14. The front end of the oil storage pipe 805 is fixedly communicated with an oil discharge pipe 8010.

[0045] Embodiment: When it is necessary to adjust the inclination angle of the photovoltaic panel 4 to ensure correct light reception, that is, when the sun is directly above, the water pump 10 can be turned on to suck the water body through the three-way valve 9. After suction, the water flow can enter the inside of the three-way valve 9 and enter the inside of the water injection valve 809 through the two water delivery pipes 11. At this time, the water flow can enter the inside of the oil storage pipe 805 and apply pressure to the piston plate 806. At this time, the piston plate 806 moves forward, and the limiting spring 808 is stretched, and the guiding block 804 is pulled to move forward. At this time, the guiding block 804 moves relative to the extension guide rail 2, and the connecting rod 803 deflects obliquely downward, so that a pulling force can be applied to the first fixing seat 801. At this time, the photovoltaic panel 4 rotates obliquely downward until the photovoltaic panel 4 is parallel to the frame 1, and the angle adjustment process is completed.

[0046] By directly sucking the clear water inside the water body by using the water pump 10 and through the cooperation between the adjusting assembly 8 and the photovoltaic panel 4, the device can actively adjust the inclination angle of the photovoltaic panel 4 without shutting down. The whole process can be automatically completed, and only by controlling the water flow rate entering the inside of the adjusting assembly 8 can the precise adjustment of the inclination angle of the photovoltaic panel 4 be realized, matching the optimal light angle and improving the power generation efficiency.

[0047] Such as Figure 1 and Figure 8As shown, the power assembly 13 includes a water storage pipe 131. The outer side surface of the water storage pipe 131 is fixedly sleeved between the second locking brackets 15. The front end of the water storage pipe 131 is fixedly communicated with an elbow pipe 134. The other end of the elbow pipe 134 is fixedly communicated with the temporary storage box 12. A return spring 136 is movably sleeved on the outer side surface of the limiting rod 133. The front and rear ends of the return spring 136 are connected to one end of the limiting plate 132 and one end of the inner cavity of the water storage pipe 131 respectively. The end of the limiting rod 133 away from the limiting plate 132 penetrates through one end of the water storage pipe 131 and is fixedly connected with a magnetic attraction plate 135.

[0048] And when the piston plate 806 displaces forward, the hydraulic oil located inside the oil storage pipe 805 can be pressed out through the oil discharge pipe 8010 and enter the inside of the temporary storage box 12 through the oil discharge pipe 8010 for temporary storage.

[0049] When the photovoltaic panel 4 is parallel to the frame 1, at this time the front side of the photovoltaic panel 4 is located below the water surface. At this time, the surface of the photovoltaic panel 4 can be assisted in cleaning through the flow of clear water to complete the preliminary cleaning process.

[0050] By utilizing the angle adjustment process of the photovoltaic panel 4, that is, when the photovoltaic panel 4 is adjusted to be parallel to the frame 1, at this time the front side of the photovoltaic panel 4 can be kept below the water surface, and self-cleaning is realized through the flow of water, so that the photovoltaic panel 4 can be self-cleaned every time it is adjusted to a specific angle, and the whole process is automatically completed, avoiding the use of manual auxiliary cleaning methods, improving the surface cleanliness of the photovoltaic panel 4, and thus improving the power generation efficiency.

[0051] Such as Figure 1 and Figure 2 as well as Figure 3 As shown, the auxiliary cleaning assembly 5 includes a limiting guide rail 501. The limiting guide rail 501 is connected to the front side of the photovoltaic panel 4. A limiting block 502 is movably clamped inside the limiting guide rail 501. A cleaning brush 503 is fixedly installed in the middle of the limiting block 502. When the photovoltaic panel 4 is parallel to the frame 1, the magnetic attraction plate 135 is located on one side of the cleaning brush 503 and is adsorbed and connected to the cleaning brush 503.

[0052] Embodiment: At the same time, when the photovoltaic panel 4 is parallel to the frame 1 and it is necessary to deeply clean the surface of the photovoltaic panel 4, the oil pump inside the temporary storage box 12 can be started, so that the hydraulic oil can be exported through the elbow pipe 134, enter the inside of the water storage pipe 131, and apply a thrust to the limiting plate 132. At this time, the limiting plate 132 and the limiting rod 133 displace backward, and the return spring 136 is stretched. At this time, the magnetic attraction plate 135 displaces toward the cleaning brush 503 until it is adsorbed to it. As the magnetic attraction plate 135 continues to displace, the cleaning brush 503 can be driven to wipe and clean the surface of the photovoltaic panel 4 to complete the deep cleaning process.

[0053] By utilizing the adjustment process of the inclination angle of the photovoltaic panel 4, the adjusted auxiliary cleaning assembly 5 corresponds to the power assembly 13. Meanwhile, by means of the cooperation among the adjustment assembly 8, the temporary storage tank 12 and the power assembly 13, through the transfer of hydraulic oil, and in coordination with the angle change of the auxiliary cleaning assembly 5, the self-cleaning of the surface of the photovoltaic panel 4 is realized. The whole process is still automatically completed, and the automatic and regular in-depth cleaning process can be achieved, improving the cleaning efficiency and thus the overall power generation efficiency.

[0054] A usage method of a buoy type photovoltaic device comprises the following steps:

[0055] S1: When the device is in normal use, the buoy 7 can be kept filled with air, the whole device floats on the water surface, and is fixed through an external cable at the same time, and the power supply of the water pump 10 is turned on to complete the preparation work;

[0056] S2: When the inclination angle of the photovoltaic panel 4 needs to be adjusted and it is adjusted towards the flat laying direction, the water pump 10 is turned on to suck water into the inside of the three-way valve 9 and input it into the inside of the oil storage pipe 805 through the water delivery pipe 11. At this time, the piston plate 806 moves forward accordingly, and pulls the guide block 804 to move leftward. At this time, the connecting rod 803 deflects accordingly and applies a downward pulling force to the photovoltaic panel 4. At this time, the photovoltaic panel 4 rotates relative to the mounting shaft 3 until it turns into a flat laying state;

[0057] S3: At this time, the photovoltaic panel 4 comes into contact with the water body. When the piston plate 806 moves forward, the hydraulic oil can be introduced into the inside of the temporary storage tank 12. At this time, the oil pump inside the temporary storage tank 12 is turned on to introduce the hydraulic oil into the inside of the water storage pipe 131. At this time, the limiting plate 132 moves backward accordingly, and drives the magnetic attraction plate 135 to move backward;

[0058] S4: When the magnetic attraction plate 135 adsorbs the cleaning brush 503, the cleaning brush 503 can be driven to displace relative to the limiting guide rail 501, and the surface of the photovoltaic panel 4 is actively cleaned to complete the self-cleaning process.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
