Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and particularly relates to a snow removal device for a photovoltaic power station.

Background Art

[0002] The Northeast region is located in the northeast of China. In winter, the climate is cold and the snowfall is heavy, which poses severe challenges to the operation and maintenance of photovoltaic power stations. The influence of snow accumulation occlusion is as follows:

[0003] (1) Reducing power generation efficiency: Snow accumulation will block the photovoltaic modules, resulting in a decrease in light intensity, and further affecting the power generation efficiency of the photovoltaic modules, which will lead to a significant decrease in the power generation of the photovoltaic modules.

[0004] (2) Causing component damage: Long-term bearing the heavy pressure of snow accumulation may cause deformation or damage to the photovoltaic modules. Especially when the snow thickness exceeds the maximum load-bearing capacity of the modules, this risk will increase further, thus affecting the service life and overall performance of the photovoltaic modules.

[0005] Most of the Northeast region adopts truss and courtyard schemes. The existing truss schemes are mainly constructed across the house. In the single-slope scheme, the rear column can reach more than 8 meters, and the power station is relatively high without a suitable snow removal scheme.

[0006] Referring to the Chinese utility model patent application with the authorization announcement number CN 222301760 U, which discloses a snow removal device for a distributed photovoltaic support ceiling, relating to the technical field of photovoltaic module snow removal. The key points of its technical solution are: The snow shoveling and transporting mechanism includes a snow shovel with a curved bottom. The power input end of the snow shoveling and transporting mechanism is connected to the first transmission component, and the power input end of the first transmission component is connected to the second transmission component. The first transmission component includes a front rotating rod, and the second transmission component includes a rear rotating rod. The front rotating rod and the rear rotating rod are driven by a belt to keep the front wheel and the rear wheel turning in the same direction to drive the whole device to move forward. The effect is that by setting a chain to drive the snow shovel, the snow shovel always moves in one direction at the part in contact with the surface of the photovoltaic panel, so that after the snow shovel shovels the snow along the slope of the photovoltaic panel, it continuously pushes the snow outwards until it slides off the edge of the photovoltaic panel.

[0007] Of course, there are many existing technologies that adopt automatic snow removal robots for automatic snow removal. However, for household photovoltaics, the cost of configuring snow removal robots is too high.

Summary of the Invention

[0008] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide a manual snow removal device for a photovoltaic system that is convenient to operate, which can perform manual snow removal more conveniently to solve the problem of too high cost of configuring snow removal robots.

[0009] To solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A manually operated snow removal device for a photovoltaic system that is convenient to operate. The photovoltaic system includes a photovoltaic support and a photovoltaic module array installed on the top of the photovoltaic support. The photovoltaic support includes columns. The snow removal device includes:

[0011] A transmission component. The transmission component is installed on the photovoltaic support. The transmission component includes a transmission wheel and an annular moving member. The transmission wheel is used to support and drive the annular moving member to move along an annular path. The annular moving member has a longitudinal movement path that runs longitudinally along the photovoltaic module array.

[0012] A snow removal component. The snow removal component is connected to the annular moving member and is driven by the annular moving member to move along the longitudinal movement path, so as to pass through the photovoltaic module array from top to bottom longitudinally and remove the accumulated snow.

[0013] A manual driving component. The manual driving component includes an operating member installed on the column. The operating member can be operated to make the manual driving component operate and drive the transmission component.

[0014] Preferably, the transmission component is a transmission chain component. The transmission chain component is installed on the first lateral side at the top of the photovoltaic support and includes a first driven sprocket, a second driven sprocket, and a first transmission chain connecting the first driven sprocket and the second driven sprocket. The first driven sprocket and the second driven sprocket are respectively installed on the upper and lower sides in the longitudinal direction at the top of the photovoltaic support.

[0015] Preferably, the transmission chain component further includes a third driven sprocket. The third driven sprocket is installed at the middle position in the longitudinal direction at the top of the photovoltaic support and is used to support the first transmission chain.

[0016] Preferably, the manual driving component includes a first driving sprocket, a second driving sprocket, and a second transmission chain connecting the first driving sprocket and the second driving sprocket. The second driving sprocket is coaxially fixed with the second driven sprocket, and the first driving sprocket is installed on the column.

[0017] Preferably, the operating member is a turntable coaxially fixed with the first driving sprocket.

[0018] Preferably, the snow removal component includes a snow removal bracket, a snow removal plate installed on the snow removal bracket, and rollers installed at the bottom of the snow removal bracket.

[0019] Preferably, the snow removal bracket includes triangular brackets provided on both lateral sides, a transverse support member corresponding to and connecting the three corners of the two triangular brackets on both sides. The triangular bracket is connected with a fixing member, and the fixing member is connected with the annular moving member.

[0020] Preferably, a limit clamping seat is provided on the second lateral side at the top of the photovoltaic support. The limit clamping seat is provided with a limit card slot extending longitudinally, and the roller is limited by the limit card slot.

[0021] Preferably, the snow removal device further includes a longitudinal extension bracket connected to the upper part of the longitudinal direction at the top of the photovoltaic support. The longitudinal extension bracket is provided with a stagnant panel located in the longitudinal upward extension direction of the photovoltaic module array, and the stagnant panel is used to park the snow removal component.

[0022] Preferably, the photovoltaic support includes a truss at the top, the truss is connected to the top end of the column, and a diagonal brace is provided between the column and the truss.

[0023] The present invention adopts the above technical solutions and has the following beneficial effects:

[0024] 1. A transmission component is installed on the photovoltaic support. The transmission component includes a transmission wheel and an annular moving part. The transmission wheel is used to support and drive the annular moving part to move along an annular path. The annular moving part has a longitudinal movement path running along the longitudinal direction of the photovoltaic module array. Moreover, the snow removal component is connected to the annular moving part and is driven by the annular moving part to run along the longitudinal movement path, so as to pass through the photovoltaic module array from top to bottom in the longitudinal direction and remove the accumulated snow.

[0025] In order to facilitate manual snow removal more conveniently, a manual driving component is provided. The manual driving component includes an operating part installed on the column. The operating part can be manually operated to make the manual driving component operate and drive the transmission component. Of course, the operating part can be installed at the middle and lower positions of the column, so that the operating position is lower and it is convenient for manual operation.

[0026] Since the photovoltaic module array is inclined longitudinally, when the snow removal component passes through the photovoltaic module array from top to bottom in the longitudinal direction and removes the accumulated snow, a certain propulsive force can be generated by virtue of the inclination of the photovoltaic module array, thereby reducing the acting force during manual operation.

[0027] The present invention can realize manual snow removal after snowfall, with simple operation, improve the power generation efficiency of the power station components in winter, speed up the snow removal progress of the power station, and at the same time can also reduce the operation and maintenance difficulty and avoid the risks brought by snow removal personnel operating on the photovoltaic module array.

[0028] 2. Since the transmission component is exposed to the natural environment, the working conditions are harsh, and the transmission resistance is large during snow removal, a transmission chain component is selected. Chain drive has a large transmission power, strong overload capacity, and a small transmission size under the same working conditions; the required tension is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust, and pollution.

[0029] 3. In the chain drive components, the first drive chain naturally sags under the action of gravity. To ensure that the first drive chain maintains an appropriate tension and position, preventing it from affecting the transmission efficiency or causing wear due to sagging, a third driven sprocket is provided. The third driven sprocket is installed at the longitudinal middle position at the top of the photovoltaic support, below the sagging section of the first drive chain, and contacts the first drive chain through its top and applies a certain upward supporting force, thereby effectively supporting the first drive chain and enabling it to maintain a stable transmission state.

[0030] 4. Given the advantages of chain drive, the manual drive component adopts the same chain drive method as the drive component. Among them, the second drive sprocket and the second driven sprocket are coaxially fixed to achieve the transmission connection between the manual drive component and the drive chain component. In addition, the first drive sprocket is installed on the column, ensuring reliable transmission and high-power transmission even for long-distance transmission.

[0031] 5. The operated part is a turntable coaxially fixed with the first driving sprocket. The turntable can be appropriately enlarged to reduce the acting force during manual operation. The turntable under the column is rotated manually, and the turntable rotates synchronously with the first drive sprocket. Through the second drive chain, the first drive chain is driven, so that the first drive chain drives the snow removal component fixed on the chain to move from high to low for snow removal operations. Finally, rotate the turntable in the reverse direction and rely on the chain to return the snow removal component to its original position.

[0032] 6. The snow removal component includes a snow removal support, a snow removal plate installed on the snow removal support, and rollers installed at the bottom of the snow removal support. Using the snow removal plate to push the snow off the photovoltaic module array can avoid snow residue. In addition, the resistance can be reduced through the rollers, making it more labor-saving when performing snow removal operations manually.

[0033] 7. The snow removal support includes triangular supports provided on both lateral sides and transverse support members corresponding to connecting the three corners of the two triangular supports on both sides. The triangular support is connected with a fixing member, and the fixing member is connected with a circular moving member. The snow removal support is overall light and has a stable and reliable structure. Since the lateral width of household photovoltaics is usually not large, the snow removal support traverses the entire lateral width of the photovoltaic module array. With one operation of the snow removal support, the snow removal operation can be completed, and the snow removal efficiency is high.

[0034] 8. Since a limit card seat is provided on the second lateral side at the top of the photovoltaic support, the limit card seat is provided with a limit card slot extending longitudinally, and the roller is limited by the limit card slot. Since the other lateral end is connected to the first drive chain, both lateral sides are limited in this way, ensuring that the snow removal component works in the same longitudinal direction from high to low.

[0035] 9. The snow removal device further includes a longitudinal extension bracket connected to the upper part of the photovoltaic bracket in the longitudinal direction. The longitudinal extension bracket is provided with a stagnant panel located in the longitudinal upward extension direction of the photovoltaic module array, and the stagnant panel is used to park the snow removal components. Therefore, for a completed power station, a longitudinal extension bracket can be newly added, and a stagnant panel for providing a parking space for the snow removal device can be installed. The snow removal components can be placed on it during non-working hours to avoid shadow occlusion and not affect normal power generation.

[0036] 10. The top of the photovoltaic bracket is a truss structure. The advantage of a truss is that the members mainly bear tension or compression, which can give full play to the role of materials, save materials, and reduce the structural weight.

[0037] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0045] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0046] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0047] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. For example, the terms such as "upper", "lower", "first direction", "second direction", etc. indicating the orientation or positional relationship are only based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0048] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0049] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0050] Refer to Figures 1 to 5 As shown, the implementation manner of the present invention provides a manually operated snow removal device for a photovoltaic system that is convenient to operate. The photovoltaic system includes a photovoltaic support 200 and a photovoltaic module array 100 installed on the top of the photovoltaic support. The photovoltaic module array 100 is usually obliquely arranged and faces the sunlight direction. The photovoltaic support 200 includes a column 22. The snow removal device includes:

[0051] A transmission component, the transmission component is installed on the photovoltaic support. The transmission component includes a transmission wheel and an annular moving member. The transmission wheel is used to support and drive the annular moving member to move along an annular path. The annular moving member has a longitudinal movement path that runs longitudinally along the photovoltaic module array;

[0052] A snow removal component, which is connected to a circular motion component and driven by the circular motion component to run along a longitudinal movement path, so as to pass through the photovoltaic module array from top to bottom in the longitudinal direction and remove the accumulated snow;

[0053] A manual driving component, which includes an operating part installed on the column, and the operating part can be operated to make the manual driving component run and drive the transmission component.

[0054] In this embodiment, in order to facilitate manual snow removal, a manual driving component is provided, in which the operating part can be manually operated to make the manual driving component run and drive the transmission component. Of course, the operating part can be installed at the middle and lower positions of the column, so that the operating position is lower and convenient for manual operation.

[0055] Since the photovoltaic module array is inclined longitudinally, during the process that the snow removal component passes through the photovoltaic module array from top to bottom in the longitudinal direction and removes the accumulated snow, a certain propulsive force can be generated by means of the inclination of the photovoltaic module array, thereby reducing the acting force during manual operation.

[0056] The present invention can realize manual snow removal after snow, with simple operation, improve the power generation efficiency of the power station components in winter, speed up the snow removal progress of the power station, and at the same time reduce the operation and maintenance difficulty and avoid the risks brought by the operation of snow removal personnel on the photovoltaic module array.

[0057] In this embodiment, the transmission component is a transmission chain component, which is installed on the top horizontal first side of the photovoltaic support, and includes a first driven sprocket 7, a second driven sprocket 5 and a first transmission chain 6 connecting the first driven sprocket 7 and the second driven sprocket 5. The first driven sprocket 7 and the second driven sprocket 5 are respectively installed on the upper and lower longitudinal sides of the top of the photovoltaic support. Since the transmission component is exposed to the natural environment with harsh working conditions and large transmission resistance during snow removal, a transmission chain component is selected. Chain drive has a large transmission power, strong overload capacity, and a small transmission size under the same working conditions; the required tension is small, and the pressure acting on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust, and pollution. Of course, it can be understood that other similar transmission methods, such as synchronous belt drive components, are not excluded for replacement.

[0058] In the above-mentioned chain transmission components, the first transmission chain 6 naturally sags under the action of gravity. To ensure that the first transmission chain 6 maintains an appropriate tension and position, preventing it from affecting the transmission efficiency or causing wear due to sagging. The transmission component further includes a third driven sprocket 8, which is installed at the longitudinal middle position of the top of the photovoltaic support and is used to support the first transmission chain 6. The third driven sprocket 8 is located below the sagging section of the first transmission chain 6, and contacts the first transmission chain through its top and applies a certain upward supporting force, thereby effectively supporting the first transmission chain and enabling it to maintain a stable transmission state.

[0059] The fixing structures of the above three sprockets can refer to the prior art. The sprockets are all fixed to the sprocket bracket 10, and the sprocket bracket 10 is then fixedly combined with the lower cross beam by a hoop 9 and bolts 11.

[0060] In this embodiment, the driving component includes a first driving sprocket 1, a second driving sprocket 4, and a second transmission chain 3 connecting the first driving sprocket and the second driving sprocket. The second driving sprocket is coaxially fixed with the second driven sprocket, and the first driving sprocket is installed on the column. The rotation of the first driving sprocket drives the second driving sprocket to rotate through the second transmission chain. Since the second driving sprocket is coaxially fixed with the second driven sprocket, the second driven sprocket also rotates simultaneously. Among them, the diameter of the first driving sprocket 1 is larger than that of the second driving sprocket 4. For example, the diameter of the first driving sprocket 1 is twice that of the second driving sprocket 4. In this way, the force during manual operation can be reduced, making it more labor-saving. It can be understood that although the second driving sprocket and the second driven sprocket are coaxially fixed and can rotate simultaneously in the same direction, their diameters and the number of teeth of the sprockets are different, so different transmission ratios can be achieved.

[0061] Furthermore, a turntable 2 is coaxially fixed to the first driving sprocket 1. In this way, rotating the turntable can drive the first driving sprocket to rotate. The turntable can be appropriately enlarged to reduce the force during manual operation. Manually rotate the turntable below the column. The turntable rotates synchronously with the first driving sprocket. Through the transmission of the second transmission chain, the first transmission chain is driven, so that the first transmission chain drives the snow removal component fixed on the chain to move from high to low for snow removal operations. Finally, rotate the turntable in the reverse direction and rely on the chain to return the snow removal component to its original position, completing the closed-loop of the snow removal work.

[0062] Specifically, the snow removal component includes a snow removal bracket, a snow removal plate 19 mounted on the snow removal bracket, and rollers 12 mounted at the bottom of the snow removal bracket. The snow removal plate 19 extends obliquely or in an arc. The snow removal bracket includes triangular brackets 13 provided on both lateral sides and transverse support members 15 connecting the three corners of the triangular brackets on both sides. The triangular brackets are connected with fixing members 14, and the fixing members are connected to the first drive chain. The triangular brackets 13 and the transverse support members 15 are combined to form a stable bracket structure, and the snow removal plate 19 is fixedly mounted on the bracket throughout the lateral direction. The snow removal bracket is overall light and has a stable and reliable structure. Since the lateral width of household photovoltaics is usually not large, the snow removal bracket spans the entire lateral width of the photovoltaic module array. The snow removal component is fixed to the first drive chain 6 through the upper fixing member 14 above, and cooperates with the rollers to achieve the longitudinal movement effect. Once the snow removal bracket operates, the snow removal operation can be completed, and the snow removal efficiency is high.

[0063] In addition, a limit clamping seat 20 is provided on the other lateral side at the top of the photovoltaic bracket. The limit clamping seat 20 is strip-shaped along the longitudinal direction and is vertically crossed with the cross beam 211, and can be fixed to the end of the cross beam by means of a hoop bolt. The limit clamping seat 20 is provided with a limit card slot extending along the longitudinal direction, and the roller 12 is limited by the limit card slot. Since the other lateral end is connected to the first drive chain, both lateral sides are limited in this way, ensuring that the snow removal component works in the same longitudinal direction from high to low.

[0064] In addition, the snow removal device further includes a longitudinal extension bracket 16 connected to the upper part of the photovoltaic bracket in the longitudinal direction. The longitudinal extension bracket is provided with a stagnant panel 17 extending in the longitudinal upper side direction of the photovoltaic module array and a panel through support 18 supporting below the stagnant panel 17. The stagnant panel is used for parking the snow removal component. The panel through support 18 can be made of square steel pipe, and the stagnant panel 17 is made of steel plate, and the two can be welded or bolted.

[0065] Specifically, the photovoltaic bracket includes a truss 21 at the top, and the truss is connected to the top end of the column. A cross beam 211 is mounted on the truss for mounting the photovoltaic module array. The longitudinal upper end of the truss is connected to the longitudinal extension bracket 16. The longitudinal extension bracket 16 extends upward in the longitudinal direction. Specifically, the longitudinal extension bracket 16 is provided with an inclined rod 161 and a longitudinal rod 162. The longitudinal rod is butted with the upper chord of the truss and is connected to the panel through support 18. One end of the inclined rod is connected to the longitudinal rod, and the other end is connected to the lower chord of the truss. The advantage of the truss is that the members mainly bear tension or pressure, which can give full play to the role of the materials, save materials and reduce the structural weight. For a completed power station, a longitudinal extension bracket 16 can be newly added, and a stagnant panel 17 for providing a parking space for the snow removal device can be installed. The snow removal component can be placed on it during non-working hours without affecting normal power generation.

[0066] Further, a diagonal brace 23 is provided between the column and the truss to enhance the overall strength of the photovoltaic support. The truss scheme is mainly for cross-building construction with a relatively high height, which is suitable for the application of the automatic snow removal device in this embodiment.

[0067] As described above, it is only the specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
