Description

Technical Field

[0001] The present invention relates to the technical field of the solar energy industry, and in particular to a fixed photovoltaic power generation array support. Background Art

[0002] A photovoltaic power generation array refers to a system that converts solar energy into electrical energy by arranging multiple photovoltaic panels in a certain way, and it is an important technology to promote the development of global renewable energy, which is of great significance for realizing a low-carbon economy and sustainable development.

[0003] When installing a photovoltaic power generation array, an installation support is essential. At the same time, in order to avoid the reduction of power generation efficiency due to the shadow occlusion of surrounding buildings, trees and other obstacles, the installation support needs to have a certain height.

[0004] However, the higher the height of the support, the higher its center of gravity, which leads to insufficient stability in some harsh environments. For example, in strong wind weather, the photovoltaic power generation array will tilt and be damaged, causing serious losses. Therefore, it is necessary to design a fixed photovoltaic power generation array support to improve its stability in harsh environments on the premise of ensuring the power generation efficiency and performance of the photovoltaic panels. Summary of the Invention

[0008] Support columns respectively slidably arranged on the corresponding counterweight seats, and a slow-speed sliding assembly is installed between each support column and the corresponding counterweight seat, and the slow-speed sliding assembly is used to enable the support column to slide relative to the counterweight seat at a slow speed;

[0009] A reinforcement frame fixedly installed between the four counterweight seats, and a wind-force lifting assembly matched with the photovoltaic panel is installed on the reinforcement frame, and the wind-force lifting assembly is used to enable the photovoltaic panel to move up and down relative to the ground;

[0010] A protection frame fixedly installed between the four counterweight seats, and a cleaning assembly matched with the photovoltaic panel is installed between the protection frame and the four counterweight seats, and the cleaning assembly is used to clean the surface of the photovoltaic panel.

[0011] Further, the lengths of the two support columns at the front end are less than those of the two support columns at the rear end, and a connecting plate is fixedly installed between every two support columns corresponding to each other in the front and rear positions. The photovoltaic panel is fixedly installed between the two connecting plates, and a connecting plate is also fixedly installed at the middle position of the bottom of the photovoltaic panel.

[0012] Further, the slow sliding assembly includes a connecting seat fixedly installed on the counterweight seat, and a fixing column is fixedly installed on the top of the connecting seat. A connecting groove is formed in the fixing column, and a connecting column fixedly connected to the support column is slidably installed in the connecting groove. A spring is installed between the bottom of the connecting column and the connecting groove. A damping ring closely attached to the side wall of the fixing column is fixedly installed on the connecting column. The cross sections of the connecting column and the connecting groove are both square.

[0013] Further, vertical blocks are fixedly installed between the front and rear side walls of the connecting column and the damping ring. Vertical grooves matched with the corresponding vertical blocks are formed on the front and rear side walls of the fixing column, and both vertical grooves communicate with the connecting groove.

[0014] Further, the wind power lifting assembly includes an installation column fixedly installed on the reinforcement frame, and a rotating rod is rotatably installed on the installation column through a bearing. A screw rod is fixedly installed on the rotating rod. A threaded sleeve in threaded cooperation with the screw rod is fixedly installed at the bottom of the middle connecting plate. A fixing ring is fixedly installed outside the rotating rod, and a plurality of fan blades are fixedly installed on the side wall of the fixing ring.

[0015] Further, the fan blades are inclined, and the edges of one side of each fan blade are arc-shaped. Reinforcing ribs are fixedly installed between the plurality of fan blades.

[0016] Further, mounting rods are fixedly installed between the protective frame and each connecting seat.

[0017] Further, the cleaning assembly includes a water storage seat fixedly installed between a plurality of counterweight seats, and a pressing plate is hermetically and slidably installed in the water storage seat. A water storage tank is arranged in the protective frame, and a flat water spraying port is formed on one side of the water storage tank close to the photovoltaic panel. A plurality of water outlet pipes communicate between the water storage tank and the water storage seat.

[0023] 3: The fixed photovoltaic power generation array bracket has the advantage of maintaining an effective height in a normal environment to ensure power generation efficiency and performance. Specifically, through the design of the slow-sliding component, when the wind force is small or disappears, the photovoltaic panel can be automatically and slowly lifted and reset smoothly to reach the predetermined height, so as to avoid being shaded by surrounding buildings or trees and reducing the power generation efficiency.

[0024] 4: The fixed photovoltaic power generation array bracket has the advantages of high automation, energy conservation and environmental protection. Specifically, through the design of the wind-powered lifting component, the cleaning component and the water collection frame, the height adjustment of the photovoltaic panel can be automatically completed by using the change of external wind force, and the accumulated rainwater can be used to achieve the cleaning treatment, without manual intervention, effectively making rational use of natural resources.

[0025] In summary, the present invention can use the wind force as the driving force in strong wind weather to automatically lower the photovoltaic panel, thereby reducing the overall center of gravity and improving stability, avoiding being blown down by strong winds and causing serious losses. Moreover, during the downward movement of the photovoltaic panel, the accumulated rainwater can be automatically used to clean its surface, effectively improving the power generation efficiency of the photovoltaic panel during subsequent use.

[0036] Referring to Figures 1-9 , a fixed photovoltaic power generation array bracket includes a photovoltaic panel 1 and four counterweight seats 2. The counterweight seat 2 is a base with a certain weight, which is used to increase the weight at the bottom of the bracket, lower the overall center of gravity, and thus improve the stability of the bracket placement. The counterweight seat 2 is made of concrete.

[0037] A connection seat 3 is fixedly installed at the upper end of each counterweight seat 2, a fixed column 4 is fixedly installed at the top of each connection seat 3, a connection column 5 is installed on each fixed column 4, and at the same time, a support column 6 is fixedly installed at the top of each connection column 5. The lengths of the two support columns 6 at the front end are less than those of the two support columns 6 at the rear end. A connection plate 7 is fixedly installed between every two corresponding support columns 6 at the front and rear positions. Since the lengths of the two front and rear support columns 6 are different, the connection plate 7 is inclined. The photovoltaic panel 1 is fixed between the two connection plates 7. The fixation between the photovoltaic panel 1 and the connection plate 7 can be achieved by bolt fixation or by using a photovoltaic clamp.

[0038] The photovoltaic panel 1 is inclined between two connecting plates 7. Since the orbit of the Earth's revolution around the sun is inclined, the angle of sunlight changes with seasons and time. The inclined installation of the photovoltaic panel 1 can better match the incident angle of sunlight, thereby receiving more solar radiation throughout the year, optimizing its power generation efficiency and performance. In addition, the inclined photovoltaic panel 1 can also reduce the time of snow covering on it, and can better reduce the accumulation of dust and dirt on it during rainwashing, which helps to maintain the high efficiency of the photovoltaic panel 1.

[0039] A connecting plate 7 is also fixed at the middle position of the bottom of the photovoltaic panel 1. A threaded sleeve 11 is fixedly installed at the middle position of the bottom of the connecting plate 7. A reinforcing frame 8 is fixedly installed between the four counterweight seats 2. The design of the reinforcing frame 8 can realize the connection between the four counterweight seats 2, thereby further improving the stability of the bracket. An installation column 9 is fixedly installed at the top of the reinforcing frame 8. A rotating rod 17 is rotatably installed on the installation column 9 through a bearing, and a screw rod 10 is fixedly installed at the bottom of the rotating rod 17. At the same time, the screw rod 10 is in threaded connection with the threaded sleeve 11. A connection groove 12 matching the corresponding connection column 5 is provided on each fixed column 4. The cross-sections of the connection column 5 and the connection groove 12 are both square. With the cooperation of the connection column 5 and the connection groove 12, the support column 6 can move up and down relative to the fixed column 4. Therefore, when the screw rod 10 rotates, the photovoltaic panel 1 can move up and down relative to the ground through its cooperation with the threaded sleeve 11. When the photovoltaic panel 1 moves down, the center of gravity of the bracket moves down again, which can further improve its stability.

[0040] Vertical blocks 15 are fixedly installed on the front and rear side walls of the connection column 5, and a damping ring 16 is fixedly installed between each pair of vertical blocks 15. The damping ring 16 is closely attached to the outer wall of the fixed column 4. The damping ring 16 can be made of a material with high surface friction. By closely attaching it to the surface of the fixed column 4, the moving resistance between the connection column 5 and the fixed column 4 can be greatly increased. Two vertical grooves 14 matching the corresponding vertical blocks 15 are provided on the side wall of the fixed column 4. A spring 13 is installed between the bottom of the connection column 5 and the connection groove 12. After the screw rod 10 is rotated by an external force to make the photovoltaic panel 1 move down, the downward movement of the connection column 5 will compress the spring 13. When the external force on the screw rod 10 disappears, the elastic force of the spring 13 will apply an upward force to the connection column 5. Therefore, the photovoltaic panel 1 will simultaneously receive an upward movement force. However, due to the threaded cooperation between the screw rod 10 and the threaded sleeve 11 and the damping effect between the damping ring 16 and the fixed column 4, the elastic release of the spring 13 will proceed slowly, so that the photovoltaic panel 1 can slowly move up and reset, avoiding the problem that its rapid up and down movement causes damage to internal components or loosening of the fixation with the connecting plate 7. In addition, under the resistance effect, the photovoltaic panel 1 will not vibrate greatly during the up and down movement process, further improving its installation stability with the bracket.

[0041] A fixing ring is also fixedly installed on the rotating rod 17. A plurality of fan blades 18 are fixedly installed on the side wall of the fixing ring. Reinforcing ribs 19 are fixedly installed between the plurality of fan blades 18. Each fan blade 18 is inclined downward from left to right (as Figure 6 shown), and the edge of the downward-deflected side of each fan blade 18 is set to be arc-shaped. The purpose of setting the angles and radian of the plurality of fan blades 18 is to make the rightward thrust exerted by the plurality of fan blades 18 under the action of wind force greater. Therefore, when the external wind force is large, the plurality of fan blades 18 can drive the rotating rod 17 and the screw rod 10 to rotate rightward through the fixing ring (that is, Figure 6 in the clockwise direction of the top view). By correspondingly setting the spiral direction on the screw rod 10 and the threaded sleeve 11, the photovoltaic panel 1 can be lowered when the screw rod 10 rotates clockwise, so as to automatically lower the center of gravity of the bracket and improve the overall stability when the external wind force is large.

[0042] An installation rod 20 is fixedly installed on the side wall of each counterweight seat 2. A protective frame 21 is fixedly installed together between the plurality of installation rods 20. When the position of the photovoltaic panel 1 remains unchanged, the photovoltaic panel 1 is located inside the protective frame 21. At this time, the protective frame 21 can protect the side surface of the photovoltaic panel 1 (as Figure 1 ), and prevent the side surface of the photovoltaic panel 1 from being damaged due to factors such as handling during the installation of adjacent photovoltaic panels 1 or the walking of equipment.

[0043] When the external wind force is large and the photovoltaic panel 1 moves downward, the protective frame 21 will move upward to a certain extent relative to the photovoltaic panel 1. At this time, if the bracket topples, the protective frame 21 will also first contact the ground, playing a protective role for the photovoltaic panel 1. And when the protective frame 21 moves upward relative to the photovoltaic panel 1, it can also block the periphery of the photovoltaic panel 1. At this time, it can prevent the strong wind from driving dust and sand to fall on the photovoltaic panel 1 and cause damage to it. At the same time, after forming the block, it can also reduce the influence of the wind force on the ejected water, thereby improving the cleaning effect. In addition, a water storage tank is arranged inside the higher end of the protective frame 21. A flat water spraying port 23 is opened on the side of the water storage tank close to the photovoltaic panel 1. A water storage seat 22 is arranged between the four counterweight seats 2. A plurality of water outlet pipes 24 are communicated between the water storage seat 22 and the water storage tank. A pressing plate 25 is hermetically and slidably installed inside the water storage seat 22. Two pressing columns 26 that are slidably matched with the water storage seat 22 are fixedly installed on the top of the pressing plate 25. Two pressing rods 27 are fixedly installed at the bottom of the connecting plate 7 in the middle, and the two pressing rods 27 are respectively aligned with the positions of the two pressing columns 26. A round plate is fixedly installed on the top of the pressing column 26, and a spring is installed between the round plate and the water storage seat 22. The water outlet pipe 24 is a one-way water outlet pipe (that is, a water outlet pipe provided with a one-way valve, and its water outlet direction allows the water in the water storage seat 22 to flow out). The connection end of the water outlet pipe 24 and the water storage seat 22 is located below the pressing plate 25.

[0044] Under the cooperation of the pressing rod 27 and the pressing column 26, when the photovoltaic panel 1 moves downward, the pressing plate 25 can move downward in the water storage base 22, so that the water at the bottom of the water storage base 22 is input into the water storage tank through a plurality of water outlet pipes 24 under pressure, and is sprayed outward onto the photovoltaic panel 1 through the flat water spray nozzle 23, thereby realizing the cleaning treatment of the surface of the photovoltaic panel 1;

[0045] And since the situation where the photovoltaic panel 1 moves downward occurs when the external wind force is relatively large, the water sprayed on the photovoltaic panel 1 will also exert a more powerful cleaning effect on the surface of the photovoltaic panel 1 under the action of the wind force.

[0046] A water collecting frame 28 is installed at the front end of the water storage base 22 through a water storage pipe 29. A filter screen 30 is fixedly installed at the bottom of the water collecting frame 28. The water collecting frame 28 is located directly below the front end of the photovoltaic panel 1. At the same time, on a rainy day, the rainwater flowing down from the front end of the photovoltaic panel 1 will fall into the water collecting frame 28. Through the filtering effect of the filter screen 30 on it, the clean rainwater will enter the water storage base 22 through the water storage pipe 29 for storage. The water storage pipe 29 is a one-way water inlet pipe (that is, a pipe equipped with a one-way valve, and can only send the water in the water collecting frame 28 into the water storage base 22 unidirectionally). The connection end of the water storage pipe 29 and the water storage base 22 is located below the lower end of the pressing plate 25, and is used to utilize the wind force to drive the photovoltaic panel 1 to move downward in an environment with a relatively large wind force to effectively clean the photovoltaic panel 1 with this part of rainwater;

[0047] And when a certain amount of rainwater accumulates in the water storage base 22, its weight will also increase the overall weight of the bottom of the bracket, so the overall stability of the bracket can also be improved.

[0048] The initial distance between the pressing rod 27 and the pressing column 26 (as Figure 1 shown) is greater than the distance between the lower surface of the flat water spray nozzle 23 and the upper surface of the protection frame 21. The purpose of setting the distance between the pressing rod 27 and the pressing column 26 is that in the initial stage of the upward movement of the photovoltaic panel 1, the rainwater in the water storage base 22 will not be sprayed out from the flat water spray nozzle 23. Only when the height of the flat water spray nozzle 23 is at the top of the photovoltaic panel 1 will it spray water outward. In this way, it can be ensured that the sprayed water can effectively fall on the upper surface of the photovoltaic panel 1. At the same time, the initial distance between the bottom of the pressing rod 27 and the inner wall of the bottom of the water storage base 22 is greater than or equal to the depth of the connecting groove 12. The purpose of the design of this dimension is to ensure that the moving stroke of the pressing rod 27 will not hinder the downward movement of the photovoltaic panel 1.

[0049] During specific installation, according to the actual situation, it is not necessary to set a water storage base 22 on each bracket. One water storage base 22 can be set for every few adjacent brackets, and the water storage base 22 can be connected to the water storage tanks in the adjacent protection frames 21 through water pipes.

[0050] In the present invention, the working principle of a fixed photovoltaic power generation array bracket is as follows:

[0051] Installation of the photovoltaic panel 1: Arrange the brackets in sequence and orderly at the installation site of the photovoltaic power generation array, and finally fix multiple photovoltaic panels 1 on the corresponding brackets through bolts or photovoltaic clamps in sequence;

[0052] Wind-induced tipping prevention: When the external wind force is relatively large, multiple fan blades 18 cause the screw 10 to rotate under the action of the wind force. At this time, under the thread fit between the screw 10 and the thread sleeve 11 and the limiting action of the connecting column 5 and the connecting groove 12, the photovoltaic panel 1 moves downward with multiple support columns 6. At this time, the overall center of gravity of the bracket moves downward, which can effectively improve its wind resistance coefficient and overall stability;

[0053] Surface cleaning treatment of the photovoltaic panel 1: When the photovoltaic panel 1 moves downward, after moving a certain distance, the pressing rod 27 contacts and pushes the pressing column 26 to move downward. At this time, the pressing plate 25 moves downward in the water storage seat 22, and the water inside the water storage seat 22 enters the water storage tank through the water outlet pipe 24 and finally sprays out from the flat water spraying port 23. Utilizing the wind force at this time, the surface cleaning treatment of the photovoltaic panel 1 can be realized;

[0054] Smooth reset of the photovoltaic panel 1: Since the downward movement of the photovoltaic panel 1 drives multiple connecting columns 5 to move downward at the same time, multiple springs 13 are continuously compressed during this process. When the external wind force disappears, the elastic force of the springs 13 will apply an upward reset force to the photovoltaic panel 1. However, due to the thread fit between the screw 10 and the thread sleeve 11 and the damping action of the damping ring 16 and the fixed column 4, the upward reset of the photovoltaic panel 1 will be completed slowly, thus realizing a smooth reset.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
