Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic power generation device. Background Art

[0002] In order to meet the green energy concept and save energy consumption, existing equipment generally uses photovoltaic power generation devices to reduce the pressure of power supply required for sewage treatment. Photovoltaic power generation technology is applied to sewage treatment equipment, which can not only reduce dependence on traditional energy, but also reduce the operating cost of sewage treatment. However, the design of existing photovoltaic power generation devices often ignores the protection of solar panels under severe weather conditions. When using photovoltaic power generation, sewage treatment equipment generally uses a large number of solar panels for power generation. For example, when encountering strong winds, it is easy to mix some debris and gravel in the strong wind, which can easily cause the debris to hit the irradiation surface of the solar panel, causing the solar panel to be damaged, affecting the photoelectric conversion efficiency, and then affecting the service life of the solar panel. In addition, when encountering heavy rain, rain will hit and cover the surface of the photovoltaic panel, affecting the solar energy collection efficiency and service life of the photovoltaic panel. Although the existing solar panels are designed with certain waterproof functions, when encountering heavy rain, heavy rain will cause water to accumulate on the surface of the solar panel, affecting its heat dissipation efficiency, and then affecting the power generation efficiency and subsequent service life, affecting the long-term stable operation and power generation effect of the solar panel.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] like Figure 1-Figure 11 As shown, a photovoltaic power generation device proposed in one embodiment of the present application includes:

[0035] A mounting frame 1, on which a solar panel 2 is obliquely mounted;

[0036] The protection mechanism 3 includes a protection plate 301 mounted on the mounting frame 1, which is used to shield the irradiation surface of the solar panel 2. A trigger 302 is installed on the mounting frame 1; the protection plate 301 is driven to move to the irradiation surface of the solar panel 2 by the trigger 302;

[0037] The pneumatic mechanism 4 includes a support frame 401 installed on the mounting frame 1, a connecting shaft 402 is movably installed on the support frame 401, a mounting plate 403 is configured on the top of the connecting shaft 402, at least three connecting rods 404 are configured on the outer peripheral side of the mounting plate 403, and a hemispherical wind cup 405 is configured on the free end of the connecting rod 404. A transfer unit 406 is installed on the mounting frame 1. When the connecting shaft 402 rotates, the connecting shaft 402 is moved downward by the transfer unit 406. When the connecting shaft 402 moves downward and contacts the trigger member 302, the trigger member 302 drives the protective plate 301 to move to the irradiation surface of the solar panel 2. When encountering strong winds, the hemispherical wind cup 405 will be driven to rotate due to the strong winds. The design of the wind cup 405 is such that when encountering strong winds, the hemispherical wind cup 405 will rotate in one direction, thereby causing the connecting shaft 402 to rotate. As the connecting shaft 402 rotates, the energy conversion unit 406 causes the connecting shaft 402 to move downward. After the connecting rod 404 moves downward to a certain distance, the bottom end of the connecting shaft 402 will contact the trigger member 302, thereby driving the trigger member 302 to drive the protective plate 301 to move, thereby causing the protective plate 301 to move and block the irradiated surface of the solar panel 2. Therefore, when encountering strong winds, when external sand and debris are flying in the air, the protective plate 301 can effectively protect the irradiated surface of the solar panel 2, thereby increasing the service life of the solar panel 2.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the protective plate 301 includes two shielding plates 3011 symmetrically rotatably mounted on the mounting frame 1. When the solar panel 2 is exposed to sunlight, the mounting frame 1 is located between the two shielding plates 3011, and the shielding surfaces of the two shielding plates 3011 are parallel to each other. A linkage assembly 5 acting on the two shielding plates 3011 is installed on the mounting frame 1. The trigger member 302 is used to drive the linkage assembly 5 to simultaneously drive the two shielding plates 3011 to rotate synchronously and in opposite directions. When the solar panel 2 is in daily use, the two shielding plates 3011 are respectively located on both sides of the two mounting frames 1, thereby effectively reducing the space occupied by the device. When the trigger member 302 is driven, the two shielding plates 3011 can be rotated synchronously and in opposite directions through the linkage assembly 5, thereby realizing the rotation of the two shielding plates 3011 and shielding the solar panel 2. At this time, the two shielding plates 3011 are combined together to effectively protect the solar panel 2 and reduce the space occupied.

[0039] like Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the linkage assembly 5 includes two groups of belt transmission members 501 symmetrically installed on the mounting frame 1, one horizontal section of the belt transmission member 501 is connected to a connecting frame plate 502, a sliding seat 503 is slidably installed on the mounting frame 1, a hinged rod 507 is hinged between the sliding seat 503 and the connecting frame plate 502, a transmission plate 504 is mounted on one of the driving rods of the belt transmission member 501, a movable groove 505 is opened on the transmission plate 504, a column rod 506 that is tangential to the movable groove 505 is constructed on the shielding plate 3011, and the trigger member 302 acts on the sliding seat 503, which is used to drive the sliding seat 503 to move. That is to say, when the trigger member 302 drives the sliding seat 503 to move, the movement of the sliding seat 503 will drive the two hinged rods 507 to move, because the hinged rods 507 are hinged on the connecting frame plate 502, so that the two connecting frame plates 502 are close to each other, because the connecting frame plates 502 are respectively It is connected to two belt transmission members 501, so as the movement of the connecting frame plate 502, the belt will be driven to move, and as the belt moves, the pulley will be driven to rotate. The rotation of the pulley drives the driving rod connected to it to rotate, and as the driving rod rotates, the transmission plate 504 connected to it is driven to rotate. Because the column rod 506 on the shielding plate 3011 is tangential to the sliding of the movable groove 505, the rotation of the transmission plate 504 will cause the column rod 506 to move in the movable groove 505, thereby driving the shielding plate 3011 to rotate. Specifically, the belt transmission member 501 includes two driving rods, and the driving rod is equipped with a pulley. A belt is installed between the two pulleys for transmission. The belt transmission member 501 is used to drive the transmission plate 504 to rotate, so that when the connecting frame plate 502 moves a small amount, the belt transmission member 501 makes the transmission plate 504 rotate greatly, and then the shielding plate 3011 can be driven to rotate quickly, thereby improving the use effect.

[0040] like Figure 7-Figure 9 As shown, in some embodiments, the trigger member 302 includes a driving part 3021 vertically slidably mounted on the mounting frame 1, and a convex plate 3022 is constructed on one side of the driving part 3021, and the convex plate 3022 is used to contact the sliding seat 503. An elastic support member 6 acting on the sliding seat 503 is installed on the mounting frame 1, and a return spring 3023 is installed between the driving part 3021 and the support frame 401. In this embodiment, when the bottom end of the connecting shaft 402 contacts the driving part 3021, the driving part 3021 will move downward, and the return spring 3023 will be stretched. When the driving part 3021 moves to a certain distance, the convex plate 3022 on the driving part 3021 will contact the sliding seat 503, and the sliding seat 503 will move quickly through the elastic support member 6. After the driving part 3021 moves a little, the sliding seat 503 will move a lot, thereby enabling the two shielding plates 3011 to rotate quickly.

[0041] like Figure 2 , Figure 6 and Fig.11 As shown, in some embodiments, the elastic support member 6 includes an articulated cylinder 601 symmetrically hinged on the mounting frame 1, a hinge plate 602 is slidably inserted at the free end of the articulated cylinder 601, a pressing spring 603 is installed between the articulated cylinder 601 and the articulated plate 602, a sliding plate 604 is hinged between the free ends of the two articulated plates 602, a convex plate 3022 is used to contact the sliding plate 604, the sliding plate 604 is vertically slidably installed on the mounting frame 1, a connecting plate 605 is constructed on the sliding plate 604, a forcing groove 606 is opened on the sliding seat 503, and a forcing groove 606 is constructed on the connecting plate 605. The rod 607 and the mounting frame 1 are symmetrically configured with an angle limiting plate 608, which is used to limit the upward rotation angle of the hinge tube 601. When the solar panel 2 is in use, the hinge tube 601 abuts against the angle limiting plate 608, and the abutting spring 603 is in a compressed state at this time. When the driving part 3021 moves downward, the downward movement of the driving part 3021 will cause the convex plate 3022 on the driving part 3021 to contact the sliding plate 604, so that the sliding plate 604 moves downward. As the sliding plate 604 moves downward, the abutting spring 603 between the hinge tube 601 and the hinge plate 602 will continue to be compressed. When the two hinged rods 507 rotate downward, the spring 603 will quickly reset due to its own elastic deformation characteristics, so that the sliding plate 604 will move downward quickly. After the driving part 3021 moves downward slightly, the sliding plate 604 will move downward rapidly and significantly. As the sliding plate 604 moves, the connecting plate 605 installed on the sliding plate 604 will also move downward. Because the forcing rod 607 constructed on the connecting plate 605 slides tangentially in the forcing groove 606, as the connecting plate 605 moves downward quickly, the forcing rod 607 will move in the forcing groove 606, thereby forcing The sliding seat 503 moves downward quickly to achieve the two shielding plates 3011 to rotate quickly at the same time and in opposite directions to protect the irradiated surface of the solar panel 2. Due to the design of the return spring 3023, when the connecting shaft 402 moves downward to drive the driving part 3021 to move downward, the return spring 3023 will be compressed to achieve the effect of moving the driving part 3021 downward. The return spring 3023 can effectively prevent the shielding plate 3011 from rotating accidentally when the external wind force is small and does not pose a greater threat to the solar panel 2. The shielding plate 3011 can only be driven to rotate when a certain wind level is reached.

[0042] like Figure 8-Figure 11As shown, in some embodiments, the energy conversion part 406 is a limiting plate constructed on the support frame 401, and a spiral guide groove 7 is opened on the outer peripheral side of the connecting shaft 402, and one end of the limiting plate is located in the spiral guide groove 7. That is to say, when the connecting shaft 402 rotates, it is equivalent to the limiting plate moving in the spiral guide groove 7, which will cause the connecting shaft 402 to move spirally downward. The design of the hemispherical wind cup 405 can better ensure the rotation direction of the connecting shaft 402 and prevent the connecting shaft 402 from moving spirally upward.

[0043] like Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments, the driving part 3021 is a water tank, the bottom of the water tank is connected with a drainage tube 8, one end of the connecting shaft 402 is penetrated with a water inlet hole 9, the top of the water tank is connected with a guide frame plate 10 located inside the support frame 401, the return spring 3023 is connected to the guide frame plate 10, and the return spring 3023 is located in the support frame 401, the connecting shaft 402 is coaxial with the guide frame plate 10, the bottom end of the connecting shaft 402 is used to contact the top of the guide frame plate 10, the top of the mounting plate 403 is provided with a conical through groove 11 connected with the water inlet hole 9, the return spring 3023 is located in the support frame 401, which plays a role in protecting the return spring 3023, and the driving part 3021 is a water tank, which is a measure of additional protection in case of heavy rain. It is improved on the original basis so that when encountering special weather, such as heavy rain and breeze, the solar panel 2 is exposed to rain for a long time, which will have a certain impact on the solar panel 2. When encountering rainy days, The rainwater will flow from the conical groove 11 into the water inlet hole 9, and finally into the guide frame plate 10. Because the guide frame plate 10 is connected to the water tank, the water level in the water tank rises, and the function of the drainage capillary 8 is to discharge the water inside the water tank. In rainy weather, the water entering the water tank will be directly discharged from the drainage capillary 8. However, in heavy rain, the speed at which the water level in the water tank rises is faster than the speed at which the water flows out of the drainage capillary 8, indicating that the rainfall at this time has been able to cause certain damage to the irradiated surface of the solar panel 2. As the water level in the water tank rises, the weight of the water tank will become heavier, and the water tank will overcome the elastic force of the return spring 3023 and move downward until the water tank continues to move downward so that the convex plate 3022 drives the sliding plate 604 to move downward, thereby realizing the rotation of the shielding plate 3011 in heavy rain and breezy weather to protect the solar panel 2. After the rain stops, the rainwater in the water tank is discharged through the drainage capillary 8 to prevent the water level inside the water tank from accumulating.

[0044] like Figure 4 , Figure 6 and Figure 8As shown, in some embodiments, a telescopic frame plate 14 is constructed on the support frame 401, and a filter cartridge 12 in contact with the top of the mounting plate 403 is constructed at the free end of the telescopic frame plate 14. A cleaning piece 13 for cleaning debris on the top of the filter cartridge 12 is installed on the connecting shaft 402. In order to prevent the holes on the filter cartridge 12 from being blocked, some branches, leaves and other impurities on the top of the filter cartridge 12 can be cleaned through the cleaning piece 13, thereby ensuring normal use on rainy days.

[0045] like Figure 6 and Figure 8 As shown, in some embodiments, the cleaning member 13 includes a water-passing frame 1301 installed in the conical through groove 11, and a cleaning plate 1302 is constructed on the water-passing frame 1301 to penetrate the filter cartridge 12, and the bottom end of the cleaning plate 1302 is in contact with the bottom end of the filter cartridge 12. That is to say, when the connecting shaft 402 moves downward in a spiral, the telescopic frame plate 14 can ensure that the filter cartridge 12 is always in coaxial contact with the top of the mounting plate 403, and as the connecting shaft 402 moves in a spiral, the cleaning plate 1302 will continue to rotate, thereby ensuring the rotation of the cleaning plate 1302 and the cleanliness of the top of the filter cartridge 12, and no additional driving force is required, which is more convenient to use.

[0046] like Figure 2 and Figure 6 As shown, in some embodiments, a drainage groove 15 is provided on one side of the mounting frame 1 that is inclined toward the drainage capillary 8. The design of the drainage groove 15 effectively prevents water in the drainage capillary 8 from directly falling onto the mounting frame 1, causing water accumulation on the mounting frame 1. Preferably, the drainage capillary 8 may also be a pipe with a larger diameter, and then a valve or a faucet such as a valve body for controlling the water flow is installed on the pipe, so that the amount of water out of the pipe can be adjusted according to actual needs.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
