Description

Technical Field

[0002] Solar energy is a clean, renewable energy source that converts light energy directly into electrical energy through solar photovoltaic panels. During use, solar photovoltaic panels usually need to be fixed with a bracket to maintain their own stability and to adapt to various usage scenarios. The bracket can be of two types: fixed and tracking. The fixed bracket has a simple structure and is easy to install; the tracking bracket can automatically adjust the angle to improve the power generation efficiency. In order to extend the service life of the bracket, the bracket material is usually made of steel or aluminum alloy, which needs to have corrosion resistance, wind and snow resistance and other properties.

[0003] During the operation of existing solar photovoltaic panels, due to the influence of the external environment, especially the accumulation of obstructions such as fallen leaves, dust, and bird excrement, the photovoltaic panels may be partially or completely blocked. This not only reduces the degree to which the photovoltaic panels receive light, but may also cause a hot spot effect, further damaging the performance of the photovoltaic panels, and ultimately leading to low power generation efficiency. Especially in outdoor camps where it rains frequently, the above-mentioned obstruction will further reduce the power generation efficiency of the photovoltaic panels. In addition, the traditional bracket design lacks flexibility and is difficult to respond quickly to emergencies or environmental changes.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 and Figure 2 As shown, an embodiment of the present invention is proposed, which proposes an assembled solar photovoltaic bracket to solve the problem that the existing solar photovoltaic panels are affected by the external environment during use, and the photovoltaic panels are blocked (such as blocked by fallen leaves), thereby resulting in low power generation efficiency. The bracket includes: a base frame 1, the base frame 1 is provided with rollers, and the angle between the base frame 1 and the ground can be changed; a sliding block 2, which is slidably connected to the base frame 1; a scraping member 301, which is fixedly connected to the sliding block 2, the scraping member 301 is in contact with the base frame 1, and the scraping member 301 is used to scrape the photovoltaic panel 101; a counterweight block 302, which is slidably connected to the base frame 1, and a connecting rope is fixedly connected between the counterweight block 302 and the scraping member 301, and the roller on the base frame 1 is used to guide the connecting rope; a transmission mechanism, which is arranged on the base frame 1, and is used to make the scraping member 301 and the base frame 1 move relative to each other.

[0020] In the above scheme, the base frame 1 is assembled from steel sections, which is used to facilitate transfer while ensuring the stability of the present invention during operation, thereby increasing the scope of application. The upper side of the base frame 1 is inclined to increase the amount of light received by the photovoltaic panel 101. The weight of the counterweight block 302 is slightly greater than the weight of the scraper 301, which facilitates the scraper 301 to slide downward along the base frame 1, thereby scraping off the fallen leaves on the photovoltaic panel 101. When in use, the base frame 1 is assembled first, and then the photovoltaic panel 101 is installed thereon. Sunlight shines on the photovoltaic panel 101 to generate electricity. In a rainy environment, due to the original light intensity, The rainfall is already lower than normal, and the rainfall is often accompanied by fallen leaves (the leaves fall due to the impact of rain), so the fallen leaves will adhere to the photovoltaic panel 101, reducing the degree of light reception by the photovoltaic panel 101. At that time, the scraping member 301 and the base frame 1 will move relative to each other through the transmission mechanism (the scraping member 301 moves downward along the base frame 1). During the process, the counterweight block 302 moves upward along the base frame 1, so that the scraping member 301 can scrape the fallen leaves on the photovoltaic panel 101, thereby ensuring the degree of light reception by the photovoltaic panel 101, and further ensuring that the power generation efficiency of the photovoltaic panel 101 in a rainy environment is maintained at a relatively high state.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the transmission mechanism includes: a water tank 401, which is fixedly connected to the base frame 1, and a water inlet is arranged on the upper side of the water tank 401. An interception net is fixedly connected to the water inlet on the water tank 401, and the interception net is arranged at an angle to facilitate the separation of impurities; a water pipe 402, which is fixedly connected and connected to the water tank 401; a rotating member 403, which is rotatably connected to the base frame 1, and the rotating member 403 is provided with a turbine, which is located in the water pipe 402, and the rotating member 403 is located below the water tank 401; a rotating shaft 404, which is rotatably connected to the base frame 1; a first rope 405, which is wound between the rotating member 403 and the rotating shaft 404; a second rope 406, which is arranged between the rotating shaft 404 and the sliding block 2; an opening and closing component, which is arranged on the base frame 1, and is used to block the water pipe 402.

[0022] In the above scheme, the axis of the turbine on the rotating member 403 is spatially perpendicular to the axis of the water flow through the water pipe 402, so as to make the rotating member 403 and the base frame 1 rotate relative to each other. The degree of interception of impurities (such as fallen leaves) by the interception net can be adaptively changed according to the actual application environment. During use in a rainy environment, rainwater enters from the water inlet on the water tank 401, and the rainwater gradually accumulates in the water tank 401. When the opening and closing component loses the blockage of the water pipe 402, the rainwater accumulated in the water tank 401 is discharged after passing through the water pipe 402. During the flow of rainwater in the water pipe 402, when the rainwater contacts the turbine on the rotating member 403, the turbine starts to drive the rotating member 403 to rotate counterclockwise (such as Figure 1 Looking in the front direction), the rotating member 403 starts to reel in the first rope 405, the first rope 405 drives the rotating shaft 404 to rotate counterclockwise, the rotating shaft 404 then reels in the second rope 406, and the second rope 406 drives the scraping member 301 to start moving downward along the base frame 1 through the sliding block 2, so as to scrape the fallen leaves on the photovoltaic panel 101. After scraping is completed, the scraping member 301 is reset under the action of the gravity of the counterweight block 302.

[0023] like Figure 3-Figure 7 As shown, the opening and closing assembly includes: a support shell 501, which is fixedly connected to the base frame 1, and the support shell 501 cuts off the water pipe 402, and the water pipe 402 is fixedly connected and communicated with the support shell 501; a baffle 502, which is slidably connected in the support shell 501, and the baffle 502 is provided with through holes and grooves arranged at intervals, and the baffle 502 is used to block the water pipe 402, and there is an angle between the baffle 502 and the horizontal plane; a float 503, which is connected to the baffle 502 by a thin rope, and the float 503 is located in the water tank 401, and a first elastic element 504 is fixedly connected between the baffle 502 and the support shell 501, and a spring block 505 is installed in the support shell 501, and the groove on the baffle 502 is used to close the spring block 505 is limited; a trigger component is arranged on the base frame 1, and is used to change the blocking state of the baffle 502 on the water pipe 402. The trigger component includes: a transmission shell 601, which is fixedly connected to the base frame 1; a piston plate 602, which is slidably connected in the transmission shell 601, and the sliding block 2 is used to squeeze the piston plate 602; a first tube 603, which is fixedly connected between the transmission shell 601 and the support shell 501, and the first tube 603 is connected to the transmission shell 601, and both are filled with transmission medium; a sliding member 604, which is slidably connected to the first tube 603, and the sliding member 604 and the spring block 505 are both provided with inclined surfaces, and the inclined surface on the sliding member 604 is used to squeeze the inclined surface on the spring block 505.

[0024] In the above scheme, the diameter of the float 503 is larger than the inner diameter of the water pipe 402, and the thin rope on the float 503 is initially in a loose state, and the baffle 502 is tilted upward from back to front, so that the upward force applied by the float 503 to the baffle 502 can make the baffle 502 and the support shell 501 slide relative to each other, and the first elastic element 504 is a spring, which is used to reset the baffle 502. The transmission medium in both the first tube 603 and the transmission shell 601 is hydraulic oil. In the process of rainwater accumulating in the water tank 401, the liquid level in the water tank 401 gradually rises, and the float 503 gradually moves upward under the action of buoyancy. After the float 503 moves upward to the point where the thin rope on it is straightened, the float 503 is pulled upward by the thin rope The baffle plate 502 moves. At this time, the spring block 505 is located in the groove on the front side of the baffle plate 502, and the baffle plate 502 is in a limited state. When the force applied by the float 503 to the baffle plate 502 is greater than the resistance of the spring block 505 to the baffle plate 502 (the spring block 505 retracts upward), the baffle plate 502 begins to slide obliquely upward along the support shell 501 under the action of the pulling force, and the first elastic element 504 is compressed. The through hole on the baffle plate 502 is gradually connected with the water pipe 402 (that is, the baffle plate 502 gradually loses its blockage of the water pipe 402), and the rainwater accumulated in the water tank 401 begins to flow downward from the water pipe 402, and the rainwater finally impacts the turbine on the rotating member 403, causing the rotating member 403 and the base frame 1 to rotate relative to each other.

[0025] During the downward movement of the sliding block 2 along the base frame 1, after the sliding block 2 moves downward to contact with the piston plate 602, the sliding block 2 drives the piston plate 602 to move downward together, and the piston plate 602 squeezes the hydraulic oil in the transmission housing 601, and the hydraulic oil in the transmission housing 601 enters the first tube 603, and the hydraulic oil in the first tube 603 squeezes the sliding member 604, and the sliding member 604 moves to the right (taking the direction shown in the figure as an example) and squeezes the spring block 505, and the spring block 505 retracts upward and loses the limit on the baffle 502, and then the baffle 502 is reset under the action of the elastic force of the first elastic element 504, and the water pipe 402 is blocked again, and at this time, the turbine on the rotating member 403 loses the power source, that is, the scraping member 301 starts to move upward (reset) along the base frame 1 under the action of the gravity of the counterweight block 302, thereby reducing the degree of intervention of the staff in the present invention and reducing the work intensity of the staff.

[0026] like Figure 6-Figure 9As shown, it also includes: a discharge shell 701, which is fixedly connected to the base frame 1, and the discharge shell 701 is provided with a water outlet. The width of the water outlet on the discharge shell 701 in the horizontal plane is greater than its height in the vertical direction. The rotating shaft 404 is fixedly connected to one end of the second rope 406, and the second rope 406 is slidably connected to the sliding block 2; an intermediate shell 702, which is fixedly connected and communicated between the discharge shell 701 and the water storage tank 401; a horizontal plate 703, which is slidably connected to the discharge shell 701, and the horizontal plate 703 blocks the water outlet on the discharge shell 701, and a spring is fixedly connected between the horizontal plate 703 and the discharge shell 701; a second pipe 704, which is fixedly connected between the sliding block 2 and the discharge shell 701, and the second pipe 704 The inside is filled with transmission medium; the extrusion piece 705 is slidably connected to the sliding block 2, the extrusion piece 705 is fixedly connected to the other end of the second rope 406, and the second elastic element 706 is fixedly connected between the extrusion piece 705 and the sliding block 2; the first extrusion block 707 and the second extrusion block 708 are both slidably connected to the second tube 704; the connecting rod 709 is fixedly connected to the cross plate 703, the extrusion piece 705, the first extrusion block 707, the second extrusion block 708 and the connecting rod 709 are all provided with inclined surfaces, the inclined surface on the extrusion piece 705 is used to limit the inclined surface on the first extrusion block 707, and the inclined surface on the second extrusion block 708 is used to limit the inclined surface on the connecting rod 709.

[0027] In the above scheme, the cross-section of the middle shell 702 is rectangular, which is used to speed up the transfer of rainwater in the water tank 401 to the discharge shell 701. The spring between the cross plate 703 and the discharge shell 701 is used to reset the cross plate 703. The transmission medium in the second tube 704 is hydraulic oil. The second elastic element 706 is a tension spring, which is used to apply tension to the sliding block 2. There is a gap between the inclined surface on the extrusion piece 705 and the inclined surface on the first extrusion block 707. In the process of the rotating shaft 404 winding up the second rope 406, the second rope 406 drives the extrusion piece 705 to move together (the extrusion piece 705 does not contact the first extrusion block 707 during the process). At the same time, the second rope 406 drives the sliding block 2 to move together by stretching the second elastic element 706 (the extrusion piece 705 and the sliding block 2 remain relatively stationary during the process). That is, the scraping member 301 moves downward along the base frame 1 to scrape off the fallen leaves on the photovoltaic panel 101. When the scraping member 301 is moved downward along the base frame 1, the fallen leaves on the photovoltaic panel 101 are scraped off. When the second elastic element 706 is in contact with the stubborn impurities on the photovoltaic panel 101, the rotating shaft 404 continues to reel in the second rope 406, but the sliding block 2 stops moving. At this time, the second elastic element 706 is further stretched, and the extrusion piece 705 continues to move with the second rope 406, and then the extrusion piece 705 contacts and squeezes the first extrusion block 707, and the first extrusion block 707 begins to move downward and squeezes the hydraulic oil in the second tube 704, and the hydraulic oil in the second tube 704 begins to squeeze the second extrusion block 708, and the second extrusion block 708 moves backward and squeezes the connecting rod 709, and the connecting rod 709 drives the cross plate 703 to move upward, and the cross plate 703 gradually loses the blockage of the water outlet on the discharge shell 701, and then the rainwater in the discharge shell 701 is discharged from the water outlet thereon, so as to flush the stubborn impurities on the photovoltaic panel 101, thereby reducing the adhesion strength of the stubborn impurities on the photovoltaic panel 101, thereby improving the scraping effect of the scraping member 301 on the stubborn impurities.

[0028] like Figure 6-Figure 8 As shown, it also includes: a third tube 801, fixedly connected between the first tube 603 and the sliding block 2, the third tube 801 is filled with a transmission medium, and the third tube 801 is connected to the first tube 603; a third extrusion block 802, slidably connected to the third tube 801, and the third extrusion block 802 is provided with an inclined surface; a limit block 803, fixedly connected to the extrusion piece 705, the limit block 803 is provided with an inclined surface, and the inclined surface on the limit block 803 is used to extrude the inclined surface on the third extrusion block 802.

[0029] In the above scheme, the transmission medium in the third tube 801 is hydraulic oil, and there is a gap between the inclined surface on the third extrusion block 802 and the inclined surface on the limit block 803, and the gap is larger than the gap between the inclined surface on the extrusion piece 705 and the inclined surface on the first extrusion block 707, which is used to change the blocking state of the baffle 502 on the water pipe 402. When stubborn impurities cannot make the scraper 301 pass after being washed by rainwater, the second rope 406 continues to pull the extrusion piece 705 to move together, and the extrusion piece 705 drives the limit block 803 to move together. After the limit block 803 contacts the third extrusion block 802, the limit block 803 starts to squeeze the third extrusion block 802, and the third extrusion block 802 starts to squeeze the hydraulic oil in the third tube 801, and the hydraulic oil in the third tube 801 enters the first tube 603, and the hydraulic oil in the first tube 603 starts to squeeze the sliding member 6 04, the sliding member 604 slides relative to the first tube 603, and at the same time, the inclined surface on the sliding member 604 presses the inclined surface on the spring block 505, and the spring block 505 retracts and loses the limit on the groove on the baffle 502, and then the baffle 502 is reset under the action of the spring elastic force, so that the baffle 502 blocks the water pipe 402, and then the rotating member 403 loses the power source, and then the scraper 301 begins to reset under the pulling action of the counterweight block 302, so as to avoid the excessive interaction force between the scraper 301 and the stubborn impurities, which causes the surface of the photovoltaic panel 101 to be damaged due to adhesion, thereby affecting its normal operation, and as the rainwater in the water tank 401 accumulates again, the scraper 301 cleans the photovoltaic panel 101 again, thereby ensuring the cleanliness of the surface of the photovoltaic panel 101 and ensuring the normal power generation.

[0030] like Figure 7 and Fig. 9 As shown, it also includes: a one-way plate 901, installed on the sliding block 2; a limiting member 902 is slidably connected to the second tube 704, the one-way plate 901 is used to squeeze the limiting member 902, and there is an angle between the axis of the sliding area of ​​the limiting member 902 in the second tube 704 and the moving direction of the one-way plate 901, which is used to make the two separate smoothly.

[0031] In the above solution, the one-way plate 901 is a spring plate that can be deformed to smoothly separate from the stopper 902. The one-way plate 901 passes from left to right (eg Fig. 9 As an example, in the process of resetting the scraping member 301, the sliding block 2 is also reset, and the sliding block 2 drives the one-way plate 901 to move together. After the one-way plate 901 contacts the limiting member 902, the one-way plate 901 drives the limiting member 902 together (as shown in FIG. Fig. 9The hydraulic oil in the second tube 704 starts to squeeze the second squeezing block 708, and the second squeezing block 708 moves backward and squeezes the connecting rod 709. The connecting rod 709 drives the cross plate 703 to move upward, and the cross plate 703 gradually loses its blockage on the water outlet on the discharge shell 701, and then the rainwater in the discharge shell 701 is discharged from the water outlet thereon, so as to finally flush the photovoltaic panel 101, and prevent the scratches (such as mud marks, etc.) on the surface of the photovoltaic panel 101 caused by the scraping member 301, thereby affecting the normal reception of light by the photovoltaic panel 101 and reducing the power generation efficiency.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
