[0022] Preferably, the photovoltaic support comprises a truss at the top, the truss is connected with the top end of the stand, and the stand and the truss are provided with a diagonal bracing rod.

[0023] The utility model discloses the above-mentioned technical scheme has the following beneficial effects:

[0024] 1. A transmission component is installed on the photovoltaic support, the transmission component comprises a transmission wheel and an annular moving part, the transmission wheel is used for supporting and driving the annular moving part to move along an annular path, the annular moving part has a longitudinal moving path for moving along the longitudinal direction of the photovoltaic module array, and the snow removing component is connected with the annular moving part and is driven by the annular moving part to move along the longitudinal moving path, so that the snow removing component passes through the photovoltaic module array from top to bottom in the longitudinal direction and removes the snow.

[0025] In order to facilitate manual snow removal, a manual driving component is arranged, and the manual driving component comprises an operated part installed on the stand.

[0026] Since the photovoltaic module array is arranged to be inclined along the longitudinal direction, when the snow removing component passes through the photovoltaic module array from top to bottom in the longitudinal direction and removes the snow, the inclination of the photovoltaic module array can generate a certain propelling force, so that the force required for manual operation is reduced.

[0027] The utility model discloses the manual snow removal after snow, simple operation, improve the winter power station component generating efficiency, accelerate the power station snow removal progress, can also reduce the operation and maintenance difficulty, avoid the risk that the snow removing personnel operates on the photovoltaic module array.

[0028] 2. Since the transmission component is exposed to the natural environment, the working condition is poor, and the transmission resistance is large when removing snow, therefore, a transmission chain component is selected, the chain transmission has large transmission power, strong overload capacity, small transmission size under the same working condition, small required tension, small pressure acting on the shaft, and can work in high temperature, humidity, dust, pollution and other harsh environments.

[0029] 3. In the chain drive component, the first drive chain sags naturally under gravity. To ensure that the first drive chain maintains proper tension and position, and to prevent it from affecting transmission efficiency or causing wear due to sag, a third driven sprocket is provided. The third driven sprocket is installed at the top longitudinal center of the photovoltaic bracket, below the sag section of the first drive chain. Its top contacts the first drive chain and applies a certain supporting force, thereby effectively supporting the first drive chain and maintaining its stable transmission state.

[0030] 4. Given the advantages of chain drive, the manual drive component adopts the same chain drive method as the transmission component. The second drive sprocket and the second driven sprocket are coaxially fixed to realize the transmission connection between the manual drive component and the transmission chain component. In addition, the first drive sprocket is mounted on the column, which can ensure reliable transmission and high-power transmission even over long distances.

[0031] 5. The operated component is a turntable fixed coaxially with the first drive sprocket. The turntable can be appropriately enlarged to reduce the force required for manual operation. The turntable below the column is rotated manually, and the turntable rotates synchronously with the first drive sprocket.

Finally, the turntable is rotated in the opposite direction, and the chain returns the snow removal component to its original position.

[0032] 6. The snow removal components include 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. The snow removal plate pushes the snow off the photovoltaic module array, which can prevent snow from remaining. In addition, the rollers can reduce resistance, making it easier to perform snow removal operations manually.

[0033] 7. The snow removal bracket includes triangular brackets on both sides of the horizontal axis and horizontal support components connecting the three corners of the triangular brackets on both sides. The triangular brackets are connected to fixing components, which are connected to the ring-shaped moving components. The snow removal bracket is lightweight and structurally stable and reliable.

[0034] 8. Because a limiting bracket is provided on the second horizontal side of the top of the photovoltaic support, and the limiting bracket has a limiting groove extending longitudinally, the roller is limited by the limiting groove.

[0050] Referring to Figures 1 to 5 The utility model discloses a kind of manual snow removal devices of photovoltaic system convenient operation, and photovoltaic system includes photovoltaic support 200 and installs the photovoltaic module array 100 on the top of photovoltaic support, photovoltaic module array 100 is usually arranged obliquely, and towards sunlight direction. Photovoltaic support 200 includes stand 22, and the snow removal device includes:

[0051] A transmission component is installed on the photovoltaic support, which comprises a transmission wheel and a ring-shaped moving component, the transmission wheel is used to support and drive the ring-shaped moving component to move along a longitudinal moving path along the longitudinal direction of the photovoltaic module array;

[0052] A snow removing component is connected with the ring-shaped moving component and is driven to move along the longitudinal moving path by the ring-shaped moving component, 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 comprises an operated component installed on the stand column, which can be operated to drive the transmission component to move.

[0054] In order to facilitate manual snow removing, the manual driving component is provided, and the operated component can be manually operated to drive the transmission component to move.

[0055] Since the photovoltaic module array is arranged in the longitudinal direction, the snow removing component can generate a certain propelling force by means of the inclination of the photovoltaic module array when passing through the photovoltaic module array from top to bottom in the longitudinal direction and removing the accumulated snow, so as to reduce the manual operation force.

[0056] The utility model discloses a manual snow removing device after snow, which is simple to operate, improves the power generation efficiency of the power station module in winter, speeds up the snow removing progress of the power station, reduces the operation and maintenance difficulty, and avoids the risk caused by the operation of the snow removing personnel on the photovoltaic module array.

[0057] In the embodiment, the transmission component is a transmission chain component, which is installed on the top transverse first side of the photovoltaic support and comprises a first driven sprocket 7, a second driven sprocket 5 and a first transmission chain 6 connected with the first driven sprocket 7 and the second driven sprocket 5, and the first driven sprocket 7 and the second driven sprocket 5 are respectively installed on the upper side and the lower side of the longitudinal direction of the top of the photovoltaic support. Since the transmission component is exposed to the natural environment, the working condition is poor, and the transmission resistance is large during snow removing, the transmission chain component is selected, the transmission chain has large transmission power, strong overload capacity, small transmission size under the same working condition, small required tension and small pressure on the shaft, and can work in high temperature, humidity, dust and pollution environment. Of course, it can be understood that other similar transmission modes, such as synchronous belt transmission component, can also be used for replacement.

[0058] The first transmission chain 6 naturally sags under the action of gravity. To ensure that the first transmission chain 6 maintains proper tension and position, and to prevent it from affecting the transmission efficiency or causing wear due to sagging. The transmission component also includes a third driven sprocket 8 mounted at the top of the photovoltaic support in the middle of the longitudinal position, 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 jacking force, thereby effectively supporting the first transmission chain and maintaining its stable transmission state.

[0059] The fixing structure of the above three sprockets can refer to the prior art. The sprockets are fixed to the sprocket support 10, which is then fixed to the lower cross beam by a combination of the hoop 9 and the bolt 11.

[0060] In this embodiment, the drive component includes a first drive sprocket 1, a second drive sprocket 4, and a second transmission chain 3 connecting the first drive sprocket and the second drive sprocket. The second drive sprocket is coaxially fixed with the second driven sprocket, and the first drive sprocket is mounted on the upright. The rotation of the first drive sprocket drives the second drive sprocket through the second transmission chain. Since the second drive sprocket is coaxially fixed with the second driven sprocket, the second driven sprocket also rotates simultaneously. The diameter of the first drive sprocket 1 is greater than that of the second drive sprocket 4, for example, the diameter of the first drive sprocket 1 is twice that of the second drive sprocket 4, which can reduce the force during manual operation and save labor. It can be understood that although the second drive sprocket and the second driven sprocket are coaxially fixed and can rotate in the same direction simultaneously, the diameters are different and the number of chain teeth is different, so different transmission ratios can be achieved.

[0061] Further, the first drive sprocket 1 is coaxially fixed with a turntable 2. In this way, rotating the turntable can drive the first drive sprocket to rotate. The turntable can be appropriately enlarged to reduce the force during manual operation. The turntable below the upright is manually rotated, and the turntable and the first drive sprocket rotate synchronously, and through the second transmission chain, the first transmission chain is driven to move the snow removal component fixed on the chain from high to low to perform snow removal work, and finally, the turntable is rotated in the opposite direction to return the snow removal component to its original position, completing the snow removal work closed loop.

[0062] Specifically, the snow removing component comprises a snow removing support, a snow removing plate 19 installed on the snow removing support, and a roller 12 installed on the bottom of the snow removing support. The snow removing plate 19 extends obliquely or in an arc shape. The snow removing support comprises triangular supports 13 arranged on both sides in the transverse direction, a transverse support member 15 corresponding to the three corners of the two triangular supports, a fixing member 14 connected to the triangular supports, and a first transmission chain connected to the fixing member. The triangular supports 13 and the transverse support member 15 are combined to form a stable support structure, and the snow removing plate 19 is fixed on the support in the transverse direction. The snow removing support is light and stable in structure. Since the household photovoltaic usually has a small transverse width, the snow removing support traverses the entire transverse width of the photovoltaic module array. The snow removing component is fixed to the first transmission chain 6 through the fixing member 14 on the top, and cooperates with the roller to achieve the longitudinal movement effect. The snow removing support can complete the snow removing operation in one operation, and the snow removing efficiency is high.

[0063] In addition, the photovoltaic support is provided with a limiting seat 20 on the other side of the top in the transverse direction. The limiting seat 20 is in a long strip shape in the longitudinal direction and is perpendicular to the cross beam 211. The limiting seat 20 can be fixed to the end of the cross beam in the form of a hoop bolt. The limiting seat 20 is provided with a limiting slot extending in the longitudinal direction, and the roller 12 is limited by the limiting slot. Since the other end in the transverse direction is connected to the first transmission chain, the limiting is performed on both sides in the transverse direction, so that the snow removing component works on the same longitudinal direction from high to low.

[0064] In addition, the snow removing device further comprises a longitudinal extension support 16 connected to the upper part of the photovoltaic support in the longitudinal direction. The longitudinal extension support is provided with a stationary panel 17 extending in the longitudinal direction on the upper side of the photovoltaic module array and a panel full-length support 18 supported below the stationary panel 17. The stationary panel is used for parking the snow removing component. The panel full-length support 18 can be a square steel tube, and the stationary panel 17 can be a steel plate. The two can be welded or bolted.

[0065] Specifically, the photovoltaic support comprises a truss 21 at the top, which is connected to the top end of the stand. The cross beam 211 is installed on the truss for installing the photovoltaic module array. The longitudinal end of the truss is connected to the longitudinal extension support 16. The longitudinal extension support 16 extends to the upper side in the longitudinal direction. Specifically, the longitudinal extension support 16 is provided with an oblique rod 161 and a longitudinal rod 162. The longitudinal rod is connected to the upper chord of the truss and connected to the panel full-length support 18. One end of the oblique rod is connected to the longitudinal rod, and the other end is connected to the lower chord of the truss. The truss has the advantage that the rod mainly bears tension or pressure, can fully play the role of the material, save materials, and reduce the weight of the structure. For the completed power station, the longitudinal extension support 16 can be added, and the stationary panel 17 for providing parking space for the snow removing device is installed. The snow removing component can be placed on the stationary panel during non-working time, which does not affect normal power generation.

[0066] Further, the column and the truss are provided with a diagonal bracing 23. The overall strength of the photovoltaic support is enhanced. The truss scheme is mainly used for construction across the house, and the height is higher, which is suitable for the automatic snow removing device in the embodiment.

[0067] The above merely describes the specific embodiments of the utility model, but the protection scope of the utility model is not limited to this, and the skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification not deviating from the function and structural principle of the utility model will be included in the scope of claims.
