Description

Technical Field

[0001] This utility model relates to the field of snow removal technology for photovoltaic power stations, specifically a highly stable snow removal component for photovoltaic power stations. Background Technology

[0002] Snow cover significantly reduces the solar panel's surface area exposed to sunlight, leading to a decrease in power generation. The primary function of snow removal systems is to promptly remove snow from the solar panel surface, ensuring the panels can fully receive sunlight and thus improve power generation efficiency. Snow removal systems typically consist of several key components. First, there's the snowplow, the core of the system, made of wear-resistant materials to effectively scrape away snow. The snowplow's design may involve mechanical brushes, rubber scrapers, etc., to adapt to different snow textures and thicknesses. Second, there's the drive system, including an electric motor and transmission mechanism, responsible for moving the snowplow across the solar panels. This system can automatically adjust the snowplow's operation based on the solar panel's tilt angle and snow thickness. Finally, the control system is equipped with sensors and controllers to monitor the snow accumulation on the solar panels in real time and automatically initiate the snow removal program when the snow accumulation exceeds a set value, ensuring efficient and safe operation.

[0003] As disclosed in CN218868187U, a snow melting device for a photovoltaic power station includes a photovoltaic panel and a snow melting mechanism. Fixed plates are installed at both ends of the photovoltaic panel. A limit rod and a screw are arranged between the two fixed plates. A limit block is slidably fitted on the side wall of the limit rod. One end of the screw passes through the fixed plate and is fitted with a first motor for driving the screw to rotate. A moving block is rotatably connected to the side wall of the screw via a thread. An mounting plate is installed at the end of the moving block and the limit block near the photovoltaic panel. A second motor drives a belt and a snow-sweeping blade to rotate, thereby... The snowplows sweep the snow off the photovoltaic panels to the ground, preventing snow accumulation. Simultaneously, electric heating elements melt any remaining ice and snow on the panels. However, in low-temperature rainy or snowy weather, moisture freezes on the photovoltaic panel surface, forming an ice layer. Due to the low outdoor temperature and continuous rain and snow, the electric heating elements struggle to melt the ice and snow adhering to the panels. Furthermore, the rotation of the snowplows only removes the snow from the panel surface, failing to generate sufficient friction to break down the ice layer. This ice layer still significantly impacts the photovoltaic panel's power generation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable snow removal component for photovoltaic power plants. A pulley traction module is added to the lower left and right sides of the photovoltaic panel frame to drive the sliding of a square crossbeam. The bottom end of the square crossbeam is fitted with an H-frame, a slanted snowplow, and a herringbone icebreaker via an elastic pressure structure, ensuring that the herringbone icebreaker and slanted snowplow are always in contact with the photovoltaic panel surface. When the pulley traction module is driven by a stepper motor, the herringbone icebreaker and slanted snowplow move along the slope of the photovoltaic panel, thereby breaking and pushing down the ice and snow layers on the photovoltaic panel, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability snow removal component for a photovoltaic power station, comprising a photovoltaic panel and pulley traction modules installed on the left and right sides of the back of the photovoltaic panel frame. A stepper motor is installed on one outer wall of the photovoltaic panel. The output end of the stepper motor is connected to a driven shaft via a coupling for driving the two pulley traction modules to work synchronously. The movable ends of the two pulley traction modules are connected to a square beam. Several elastic pressure structures are installed at the bottom of the square beam. The movable ends of the elastic pressure structures are connected to a lower H-frame. A herringbone icebreaker is fixed inside the lower H-frame. An angled snowplow is fixed between the opposite outer walls of two adjacent lower H-frames. The lower surfaces of the herringbone icebreaker and the angled snowplow are in contact with the surface of the photovoltaic panel. A motor controller is installed on one side of the bottom of the photovoltaic panel. The output end of the motor controller is electrically connected to the input end of the stepper motor.

[0006] Preferably, the pulley traction module includes two convex seats fixed on one side of the back of the photovoltaic panel, a shaft frame fixed on the outer wall of one side of the convex seats, a synchronous wheel rotatably installed inside the shaft frame, and a transmission belt wound between the two synchronous wheels. A sliding sleeve is fixed to one end of the surface of the transmission belt, and a right-angle frame is fixed to the upper surface of the sliding sleeve. The square crossbeam is fixed to the top of the two right-angle frames, and the stepper motor drives the synchronous wheel to rotate through the driven shaft.

[0007] Preferably, the bottom ends of the two convex bases on the same side extension line are fixed with guide rails, and the upper surface of the sliding sleeve and the lower surface of the guide rail are slidably connected.

A spring is fitted on the outer circumference of the sliding rod.

[0010] Preferably, the inner wall of the lower H-frame and the outer wall of the diagonal brace are welded together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-stability snow removal component for photovoltaic power stations is equipped with a structure that includes a wheeled traction module, a square crossbeam, an angled snow pusher, and a herringbone icebreaker. The wheeled traction module is driven by a stepper motor, which enables the herringbone icebreaker and the angled snow pusher to move evenly along the slope of the photovoltaic panel. This mechanized cleaning method can effectively push the ice and snow off the photovoltaic panel, avoiding the unevenness and incompleteness caused by manual cleaning. Moreover, the elastic pressure structure can ensure that the herringbone icebreaker and the snow pusher always maintain appropriate contact force with the surface of the photovoltaic panel. On the one hand, it can effectively prevent scratches or damage to the surface of the photovoltaic panel caused by excessive friction, and on the other hand, it can break the ice and snow layer on the surface of the photovoltaic panel.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5 This utility model provides an embodiment of a high-stability snow-sweeping component for photovoltaic power stations, comprising a photovoltaic panel 1 and pulley traction modules 2 mounted on the left and right sides of the back of the photovoltaic panel 1 frame. A stepper motor 3 is mounted on one outer wall of the photovoltaic panel 1. The output end of the stepper motor 3 is connected to a driven shaft 7 via a coupling for driving the two pulley traction modules 2 to work synchronously. The movable ends of the two pulley traction modules 2 are jointly equipped with a square crossbeam 6, which has good load-bearing capacity to ensure stable snow removal during snow sweeping. Stable operation during the process; several elastic pressure structures 11 are installed at the bottom of the square beam 6, and a lower H frame 8 is installed at the movable end of the elastic pressure structure 11. A herringbone ice-breaking blade 10 is fixed inside the lower H frame 8, and a slanted snow-pushing board 9 is fixed between the opposite outer walls of two adjacent lower H frames 8. The lower surfaces of the herringbone ice-breaking blade 10 and the slanted snow-pushing board 9 are in contact with the surface of the photovoltaic power generation panel 1. The elastic pressure structure 11 can adjust the pressure according to the thickness of the ice and snow to ensure that the ice-breaking blade and the snow-pushing board are in effective contact with the photovoltaic power generation panel 1.

[0020] A motor controller 5 is installed on one side of the bottom of the photovoltaic panel 1. The output terminal of the motor controller 5 is electrically connected to the input terminal of the stepper motor 3.

[0021] The pulley traction module 2 includes two convex seats 201 fixed to one side of the back of the photovoltaic panel 1, a shaft frame 202 fixed to the outer wall of one side of the convex seat 201, a synchronous pulley 203 rotatably mounted inside the shaft frame 202, and a transmission belt 206 wound between the two synchronous pulleys 203. A sliding sleeve 205 is fixed to one end of the surface of the transmission belt 206, and a right-angle bracket 4 is fixed to the upper surface of the sliding sleeve 205. A square crossbeam 6 is fixed to the top of the two right-angle brackets 4. A stepper motor 3 drives the synchronous pulleys 203 to rotate through a driven shaft 7. When the pulley traction module 2 is working, the rotational power of the stepper motor 3 is transmitted to the driven shaft 7, which drives the two pulley traction modules 2 to work synchronously. The driven shaft 7 drives the synchronous wheel 203 in the shaft frame 202 to rotate, thereby causing the transmission belt 206 to rotate. The transmission belt 206 pulls the sliding sleeve 205, the right-angle frame 4, and the square crossbeam 6 to slide in the extension direction of the guide rail 204, so that the slanted snowplow 9 and the herringbone ice-breaking blade 10 slide on the surface of the photovoltaic panel 1, thereby removing the ice and snow layers. The motor controller 5 can adjust the operating status of the stepper motor 3 in real time according to environmental changes. The stepper motor 3 can precisely control the movement step to ensure the effective coverage of the sweeping equipment. This allows the pulley traction module 2 to adjust the sweeping range according to actual needs and adapt to photovoltaic panels 1 of different sizes and shapes.

[0022] The bottom ends of the two convex seats 201 on the same side extension line are fixed with guide rails 204. The upper surface of the sliding sleeve 205 and the lower surface of the guide rail 204 are slidably connected. The sliding sleeve 205 and the guide rail 204 are used to improve the sliding stability of components such as the slanted snow pusher 9 and the herringbone icebreaker 10. The slanted snow pusher 9 and the herringbone icebreaker 10 are both made of aluminum alloy. The angled design of the slanted snow pusher 9 allows snow and ice to slide off more easily, reducing the possibility of residue. The herringbone design of the herringbone icebreaker 10 enables it to effectively cut into the ice layer, quickly break the ice, and reduce the resistance during cutting.

[0023] The elastic pressure structure 11 includes a U-shaped frame 1102 fixed to the surface of the square beam 6, a diagonal arm 1101 hinged to the bottom end of the square beam 6, and a partition 1103 fixed at one end inside the diagonal arm 1101. A slide rod 1104 is slidably installed inside the partition 1103. The top end of the slide rod 1104 extends into the interior of the U-shaped frame 1102 and is hinged to the U-shaped frame 1102. A spring 1105 is fitted on the outer periphery of the slide rod 1104. The inner wall of the lower H-frame 8 and the outer wall of the diagonal arm 1101 are welded together.

[0024] The elastic force of the spring 1105 forces the inclined arm 1101 to swing downward, so that the lower surfaces of the inclined snowplow 9 and the herringbone icebreaker 10 press against the photovoltaic power generation panel 1, so that there is sufficient contact pressure between the inclined snowplow 9, the herringbone icebreaker 10 and the photovoltaic power generation panel 1, and so that the inclined snowplow 9 and the herringbone icebreaker 10 can move better.

[0025] In this embodiment, when in use, the component is initially in standby mode when there is no snow or ice. At this time, the stepper motor 3 is not activated by the motor controller 5, and the pulley traction module 2 is stationary. The photovoltaic panel 1 operates normally with high power generation efficiency. When the outdoor temperature drops and snowfall, rain, or freezing occurs, the photovoltaic power station's weather monitoring system can automatically detect these changes. Once snow or ice is detected, the operator sends a working signal to the motor controller 5. Upon receiving the signal, the controller activates the stepper motor 3, thereby starting the pulley traction module 2. The rotation of the pulley causes the square beam 6 to move in the front-back direction of the photovoltaic panel 1. The bottom end of the square beam 6 is connected to the lower H-frame 8 via an elastic pressure structure 11. The lower H-frame 8 fixes the herringbone icebreaker 10 and the angled snowplow 9. The elastic pressure structure 11 ensures the stability of the herringbone icebreaker 9 and the icebreaker... The ice blade 10 maintains proper contact with the surface of the photovoltaic panel 1. The herringbone ice-breaking blade 10 cuts into the ice layer during movement, using its unique shape and cutting edge to break the ice. The structural design of the herringbone ice-breaking blade 10 allows it to easily cut the ice layer and reduce damage to the surface of the photovoltaic panel. After the ice-breaking blade cuts the ice layer, the angled snow pusher 9 then pushes the ice and snow layer. The angled design of the snow pusher makes the snow pushing action more effective, pushing the broken ice and snow down along the edge of the photovoltaic panel to prevent it from accumulating again. As the square crossbeam 6 continues to move, the ice and snow are gradually cleared. Through the dual action of ice breaking and snow pushing, the snow and ice layer on the surface of the photovoltaic panel are effectively removed, ensuring that the photovoltaic panel returns to the best light reception state. Once the surface of the photovoltaic panel 1 is clean, the motor controller 5 controls the stepper motor 3 to stop rotating, the pulley traction module 2 returns to the initial position, and the module re-enters the standby state.
