Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module auxiliary tools, and in particular to a lightweight and quick photovoltaic module snow removal device. Background Technology

[0002] A photovoltaic (PV) module snow removal device is a specialized device or system designed to remove snow covering the surface of solar photovoltaic modules. When PV modules are covered with snow, their power generation efficiency drops significantly, or even stops completely. Therefore, timely snow removal is crucial for maintaining the efficient operation of PV systems.

[0003] In related technologies, snow removal devices are typically installed directly on photovoltaic modules. When snow accumulates on the surface of the photovoltaic panel, a servo motor starts, driving a screw to rotate, which in turn moves a threaded sliding strip along a sliding opening. A clearing strip is fixed to the bottom of the sliding strip. As the sliding strip moves, the clearing strip scrapes away the snow on the surface of the photovoltaic panel, ensuring that the photovoltaic panel can effectively receive sunlight.

[0004] However, this snow removal device has a significant drawback: in order to ensure that the snow covering the surface of each photovoltaic module can be effectively removed, it is often necessary to configure a separate snow removal device for each module, which greatly increases the manufacturing cost. Utility Model Content

[0005] The main purpose of this invention is to provide a lightweight and quick snow removal device for photovoltaic modules, solving the problem of snow removal from photovoltaic modules.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lightweight and quick snow removal device for photovoltaic modules, comprising: First translation rod; The second translation rod is spaced apart from the first translation rod. The first and second translation rods, together with the two diagonal rods, form a translation frame. Both sides of the bottom of the translation frame are provided with pulleys, which are used to drive the translation frame to move laterally along the surface of the photovoltaic module. The snow removal pole has one end connected to the first translation pole and the other end connected to the second translation pole, and the snow removal pole is inclined between the first translation pole and the second translation pole.

[0007] In the preferred embodiment, the two ends of the first translation rod are respectively fixedly connected to the diagonal rods, one end of the second translation rod is fixedly connected to one of the diagonal rods, and the other diagonal rod is fixedly connected to the second translation rod.

[0008] In the preferred embodiment, the first and second translation rods are arranged parallel to the upper and lower edges of the photovoltaic module, and the two diagonal rods form an angle with the side of the photovoltaic module, so as to enable the first or second translation rod to pass through the span first.

[0009] In the preferred embodiment, the first translation rod, the second translation rod, and the diagonal rod form a parallelogram frame.

[0010] In a preferred embodiment, a push rod is provided on one side of the top of one of the inclined rods, and the end of the push rod is located away from the first translation rod. A reinforcing rod is provided on the side of the push rod at an angle, and one end of the reinforcing rod is fixed to the push rod, while the other end is fixed to the intersection of the second translation rod and the inclined rod. A grip is fixed at the top of the push rod.

[0011] In the preferred embodiment, the first translation rod and the second translation rod are arranged in parallel and spaced apart, and two diagonal rods are arranged in parallel and spaced apart and fixed at an incline to the first translation rod and the second translation rod.

[0012] In a preferred embodiment, the end of the first or second translation rod is provided with an extension section, which is used to cross the gap between each photovoltaic module.

[0013] In the preferred embodiment, the pulley components include a first pulley and a second pulley. Support frames are provided on both sides of the bottom foot of the first translation rod, and a first pulley is installed on each support frame. A second pulley is installed on both sides of the bottom foot of the second translation rod.

[0014] In the preferred embodiment, each support frame is slidably connected to two first pulleys, and each pair of first pulleys is engaged in a channel steel provided on the back of the photovoltaic module. Both the first pulleys and the second pulleys slide along the horizontal direction of the photovoltaic module.

[0015] In the preferred embodiment, a silicone scraper is provided on the side of the snow removal bar.

[0016] The beneficial effects of this lightweight and fast photovoltaic module snow removal device are as follows: 1. The first and second translation rods, along with two diagonal rods, are fixed together to form a stable parallelogram structure. This design facilitates the continuous and smooth movement of the frame between photovoltaic modules, enabling sequential transitions and avoiding the need for manual handling of equipment to the next photovoltaic module location, as required in traditional construction. This significantly saves manpower and improves work efficiency. 2. Each set of second pulleys is set in pairs, which can be precisely engaged in the channel steel rail to ensure that the frame slides smoothly along the rail, while effectively preventing deviation or shaking, greatly improving the stability and safety during operation; 3.

[0019] Example 1 like Figure 1-4 As shown, a lightweight and quick snow removal device for photovoltaic modules comprises a translation frame consisting of a first translation rod 1, a second translation rod 2, and a diagonal rod 3. The end of either the first translation rod 1 or the second translation rod 2 has an extension section for bridging the gap between each photovoltaic module. The diagonal rod 3 is obliquely fixed to the first translation frame 1 and the second translation frame 2. The pulleys are a first pulley 7 and a second pulley 8, respectively. The first pulley 7 is located at the base of the first translation frame 1, and the second pulley 8 is located at the base of the second translation frame 2. The first pulley 7 and the second pulley 8 are used for translation on the photovoltaic panel. A channel steel with an outward-facing groove is installed on the back of the photovoltaic module. The first pulley 7 can move within the channel steel, and the second pulley 8 moves on the surface of the photovoltaic module. The diagonal rod 3 is obliquely fixed between the first translation rod 1 and the second translation rod 2. When the first pulley 7 and the second pulley 8 move on the photovoltaic module, the snow removal rod 4 moves along with the first translation rod 1 and the second translation rod 2, clearing the snow from the photovoltaic module.

[0020] The first translation rod 1, the second translation rod 2, the diagonal rod 3, and the snow removal rod 4 are fixed to each other by welding or by bolts, and the bolted connection facilitates disassembly. The two ends of the first translation rod 1 are fixedly connected to the diagonal rod 3, and one end of the second translation rod 2 is fixedly connected to one of the diagonal rods 3, while the other diagonal rod 3 is fixedly connected to the second translation rod 2.

[0021] The first translation rod 1, the second translation rod 2, and the diagonal rod 3 form a parallelogram frame. A push rod 5 is located on one side of the top of one of the diagonal rods 3, with the end of the push rod 5 furthest from the first translation rod 1. The entire frame is moved laterally by a person holding onto the push rod 5. Because the photovoltaic modules are tilted, the push rod 5 is positioned downwards from the photovoltaic modules, facilitating manual pushing and supporting the entire frame. The entire frame is constructed of lightweight, high-strength components, saving manpower when moving the entire frame onto the photovoltaic modules.

[0022] The first translation rod 1 and the second translation rod 2 are arranged parallel to each other and spaced apart. Two diagonal rods 3 are arranged parallel to each other and are fixed at an angle to the first translation rod 1 and the second translation rod 2. Support frames 6 are provided on both sides of the bottom of the first translation rod 1, and a first pulley 7 is installed on each support frame 6. Second pulleys 8 are installed on both sides of the bottom of the second translation rod 2. Two first pulleys 7 are slidably connected to each support frame 6, and every two first pulleys 7 are arranged correspondingly. A silicone scraper is fixedly connected to the side of the snow removal rod 4 facing the photovoltaic module. The silicone scraper can prevent scratching the surface of the photovoltaic module.

[0023] The first pulley 7 rolls within the channel steel, ensuring precise movement and preventing deviation. The second pulley 8 uses a wide-faced anti-slip rubber wheel that rolls directly against the photovoltaic glass surface, adapting to different snow thicknesses and avoiding scratches on the photovoltaic module surface. The snow removal rod 4 is tilted to the left. As the snow removal rod 4 moves laterally with the first translation rod 1 and the second translation rod 2, the snow removed by the snow removal rod 4 falls downwards and slides through the gap between the second translation rod 2 and the photovoltaic module surface. The tilted setting of the snow removal rod 4 ensures overall stability and divides the entire frame into two triangles, which provide stability.

[0024] Example 2 A lightweight and quick snow removal device for photovoltaic modules includes: a first translation rod 1; a second translation rod 2, which is spaced apart from the first translation rod 1, the first translation rod 1 and the second translation rod 2, together with two diagonal rods 3, form a translation frame, and pulleys are provided on both sides of the bottom of the translation frame, the pulleys being used to drive the translation frame to move laterally along the surface of the photovoltaic module; and a snow removal rod 4, one end of which is connected to the first translation rod 1 and the other end of which is connected to the second translation rod 2, and the snow removal rod 4 is inclined between the first translation rod 1 and the second translation rod 2.

[0025] Furthermore, the first translation rod 1 and the second translation rod 2 are arranged in parallel and together with the diagonal rod 3 to form a translation frame, so that this structure can achieve the span between the two photovoltaic modules. The photovoltaic panels in the photovoltaic modules are set at an angle to better receive sunlight. Both the first translation rod 1 and the second translation rod 2 are equipped with pulleys, which facilitate movement on the photovoltaic panels and will not scratch the surface of the photovoltaic panels.

[0026] The two ends of the first translation rod 1 are fixedly connected to the diagonal rods 3 respectively, one end of the second translation rod 2 is fixedly connected to one of the diagonal rods, and the other diagonal rod 3 is fixedly connected to the second translation rod 2.

[0027] Furthermore, the first translation rod 1 and the second translation rod 2 are arranged in parallel and spaced apart, and two diagonal rods 3 are also arranged in parallel and spaced apart. The two ends of the two diagonal rods 3 are fixedly connected to the first translation rod 1 and the second translation rod 2, respectively, and the two diagonal rods 3 are inclined and fixedly connected to the first translation rod 1 and the second translation rod 2 to facilitate the crossing between photovoltaic panels. The length of the second translation rod 2 is longer than that of the first translation rod 1, so that when the entire structure moves on the photovoltaic panels, the second translation rod 2 will preferentially translate to the next photovoltaic panel.

[0028] The first translation rod 1 and the second translation rod 2 are set parallel to the upper and lower edges of the photovoltaic module, and the two diagonal rods 3 form an angle with the side of the photovoltaic module, so as to enable the first translation rod 1 or the second translation rod 2 to pass through the span first.

[0029] Furthermore, the photovoltaic panel in the photovoltaic module is tilted, the first translation rod 1 is parallel to the upper edge of the photovoltaic panel, the second translation rod 2 is parallel to the lower edge of the photovoltaic panel, and the two inclined rods 3 are tilted and fixed to the first translation rod 1 and the second translation rod 2. The two inclined rods 3 form an angle with the side of the photovoltaic panel to enable the first translation rod 1 or the second translation rod 2 to pass over the span first.

[0030] The first translation rod 1, the second translation rod 2, and the diagonal rod 3 form a parallelogram frame.

[0031] Furthermore, since the inclined rod 3 is inclined to the first translation rod 1 and the second translation rod 2, and the two inclined rods 3 are parallel to each other, and the first translation rod 1 and the second translation rod 2 are parallel to each other, the first translation rod 1, the second translation rod 2 and the inclined rod 3 form a parallelogram frame, which facilitates the second translation rod 2 to be preferentially translated to the next photovoltaic panel.

[0032] One of the inclined rods 3 has a push rod 5 on one side of its top, and the push rod 5 is located away from the end of the first translation rod 1. The side of the push rod 5 is provided with a reinforcing rod 9, and one end of the reinforcing rod 9 is fixed to the push rod 5, and the other end is fixed to the intersection of the second translation rod 2 and the inclined rod 3. The top of the push rod 5 is fixed with a grip rod 10.

[0033] Furthermore, push rod 5 is fixed to one of the inclined rods, and the end of push rod 5 is set away from the first translation rod 1. Push rod 5 can assist the translation of this structure. A reinforcing rod 9 is provided on the side of push rod 5 at an angle to strengthen the stability of push rod 5 and prevent it from becoming unstable after long-term use. A handle 10 is fixedly installed at the top of push rod 5. When translation is required, the operator can hold the handle 10 and move it forward.

[0034] The first translation rod 1 and the second translation rod 2 are arranged in parallel and spaced apart, and two diagonal rods 3 are arranged in parallel and spaced apart and are fixed at an angle to the first translation rod 1 and the second translation rod 2.

[0035] Furthermore, the first translation rod 1 and the second translation rod 2 are arranged parallel to each other, and the two diagonal rods 3 are arranged at an angle to the first translation rod 1 and the second translation rod 2. The first translation rod 1, the second translation rod 2 and the two diagonal rods 3 are made of lightweight metal or plastic materials, which makes it easy for operators to push them.

[0036] The end of the first translation rod 1 or the second translation rod 2 is provided with an extension section, which is used to cross the gap between each photovoltaic module.

[0037] Furthermore, either the first translation rod 1 or the second translation rod 2 may be provided with an extension section to facilitate the first translation rod 1 or the second translation rod 2 to cross the photovoltaic panel, while the second translation rod 2 must be extended.

[0038] The pulley components include a first pulley 7 and a second pulley 8. Support frames 6 are provided on both sides of the bottom of the first translation rod 1, and the first pulley 7 is installed on each support frame 6. The second pulley 8 is installed on both sides of the bottom of the second translation rod 2.

[0039] Furthermore, the first pulley 7 is installed on the first translation rod 1, and the second pulley 8 is installed on the second translation rod 2. There are two sets of the first pulley 7, and each set of the first pulley 7 has two pulleys. The back of the upper edge of the photovoltaic panel is equipped with a channel steel with the opening facing outward. The two sets of first pulley 7 can move in the channel steel so that the snow removal rod 4 can contact the surface of the photovoltaic panel.

[0040] Each support frame 6 is slidably connected to two first pulleys 7. Each pair of first pulleys 7 is engaged in the channel steel provided on the back of the photovoltaic module. Both the first pulleys 7 and the second pulleys 8 slide along the horizontal direction of the photovoltaic module.

[0041] Furthermore, each set of first pulleys 7 is mounted on the first translation rod 1 via a support frame 6. Every two first pulleys 7 are arranged opposite each other and run parallel in the channel steel provided on the back of the photovoltaic panel, so that the entire translation frame moves on the photovoltaic panel along with the first pulleys 7 and the second pulleys 8.

[0042] The snow removal rod 4 has a silicone scraper on its side.

[0043] Furthermore, the snow removal rod 4 has multiple parallel silicone scrapers mounted on its side, which are detachable and easy to replace. Multiple slots are provided on both the side facing the photovoltaic panel and the side opposite to it, allowing the silicone scrapers to engage directly in these slots. This prevents accumulated snow from falling onto already cleared areas. The side of the snow removal rod 4 facing away from the photovoltaic panel can also be raised to further prevent snow from falling onto cleared areas. The snow removal rod 4 is angled and fixed at opposite corners of a parallelogram, facilitating the falling of cleared snow.

[0044] In summary, the implementation principle of this embodiment is as follows: The first translation rod 1, the second translation rod 2, and the diagonal rod 3 form a parallelogram frame. The length of the second translation rod 2 is longer than that of the first translation rod 1. The diagonal rod 3 is fixed obliquely to the first translation rod 1 and the second translation rod 2. The first pulley 7 is located on the base of the first translation rod 1, and the second pulley 8 is located on the base of the second translation rod 2. Since the photovoltaic modules are inclined, a channel steel is provided on the upward-facing back of the photovoltaic modules. The first pulley 7 rolls in the channel steel, and the second pulley 8 rolls on the surface of the photovoltaic modules. Each photovoltaic module is spaced apart, and the entire frame is parallelogram-shaped. Because the second translation rod 2 is relatively long, the second pulley 8 on the second translation rod 2 will reach the next photovoltaic module first when the frame moves. The first pulley 7 on the first translation rod 1 then rolls in the channel steel, preventing the entire frame from tilting or becoming unstable, and ensuring that the frame continuously clears snow from each photovoltaic module. The snow removal pole 4 is tilted and fixed at the diagonal of the first translation pole 1 and the second translation pole 2. When the entire frame moves, the snow removal pole 4 cleans the photovoltaic modules.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
