Description

Technical Field

[0001] The utility model relates to the field of photovoltaic coating, and in particular comprises a wheeled walking mechanism. Background Art

[0002] Photovoltaic panels, as the core components of solar photovoltaic power generation systems, use photovoltaic panels made of battery semiconductor materials to convert sunlight into electrical energy through the photovoltaic effect. In large-scale photovoltaic power stations, photovoltaic panels are often arranged in arrays and need to adapt to changes in natural factors such as terrain and light. Therefore, wheeled walking mechanisms, as key equipment for the maintenance and cleaning of photovoltaic panels, play an indispensable role in photovoltaic power stations.

[0003] The wheeled walking mechanism realizes the movement and positioning of the equipment by rolling its driving wheels on the photovoltaic panels. However, the existing wheeled walking mechanism still has some shortcomings. First, in terms of obstacle crossing ability, when encountering gaps between photovoltaic panels or raised obstacles, the wheels of the walking mechanism are easily stuck, causing the equipment to fail to operate normally. Secondly, in terms of stability, since the surface of the photovoltaic panel is smooth and there is an inclination, the walking mechanism is prone to sliding or tipping over during driving, which brings safety hazards to equipment maintenance and other work.

[0021] As an example, Figures 1 to 3 As shown, this wheeled walking mechanism, two wheeled walking mechanisms are symmetrically arranged at the two ends of the photovoltaic module spray coating device, the wheeled walking mechanism includes: a walking mechanism base plate 3, walking wheels and limiting wheels 13, the walking mechanism base plate 3 is placed vertically, and its length direction extends in the horizontal direction, the walking wheels are vertically arranged at the two ends of the opposite sides of the two walking mechanism base plates 3, corresponding to the edges of the upper and lower ends of the photovoltaic module, one of the two walking wheels connected to the walking mechanism base plate 3 is connected to a motor 11, which is used for the overall drive of the wheeled walking mechanism and keeps the wheeled walking mechanisms at both ends of the photovoltaic module spray coating device moving synchronously. This method is the power basis of the wheeled walking mechanism.

[0022] The walking wheel includes a walking wheel axle 7 and a driving wheel core 4. The walking wheel axle 7 passes through the walking mechanism base plate 3. The walking wheel axle 7 is fixedly connected to the driving wheel core 4 at one end facing the photovoltaic module. The walking wheel axle 7 is rotatably connected to the walking mechanism base plate 3 through a deep groove ball bearing 5. The walking wheel axle 7 connected to one end of the driving wheel core 4 is fixed with a driving wheel pressure cover 1, and the other end is fixed with a pressure cover 9.

[0023] The motor 11 is arranged on the side of the walking mechanism base plate 3 away from the photovoltaic module. The outer casing of the motor 11 is fixedly connected to the walking mechanism base plate 3 by several bolts upward. The end of the walking wheel shaft 7 of the walking wheel connected to the motor 11 is fixed with a walking mechanism flange 10. The output end of the motor 11 and the walking mechanism flange 10 are fixedly connected by bolts. Therefore, when the motor 11 rotates, the outer casing of the motor 11 is fixed, and the output end drives the walking wheel shaft 7 and the driving wheel core 4 to rotate through the walking mechanism flange 10.

[0024] Angle brackets 14 are fixedly connected below the two ends of the bottom plate 3 of the walking mechanism. The side of the angle bracket 14 away from the photovoltaic module is connected to the walking roller lower plate 15 through bolts, and the bolts are covered with compression springs. Specifically, the walking roller lower plate 15 includes a flat plate and a vertical plate. One side of the flat plate is fixed to the angle bracket 14. The vertical plate is fixed to the two ends of the flat plate. The limiting wheel 13 rotates on the horizontal plane. The limiting wheel 13 is arranged between the two vertical plates below the flat plate, and the rotating shaft of the limiting wheel 13 is connected to the flat plate. The vertical plate and the angle bracket 14 are connected by bolts covered with compression springs. By adjusting the tightening degree of the bolts and nuts, the position of the limiting wheel 13 can be adjusted, and the size of the photovoltaic module can be adapted within a certain range. Bolts covered with compression springs are arranged on both sides of the limiting wheel 13, so that the limiting wheel 13 can be effectively provided with a tensioning force toward the photovoltaic module.

[0025] The limiting wheel 13 extends a certain distance from the bottom of the angle frame 14 to contact the outside of the photovoltaic module frame. The running wheel rolls on the surface of the photovoltaic module frame, wherein the running wheel connected to the motor 11 is the driving wheel, and the other running wheels and the limiting wheel 13 are all driven wheels. The limiting wheels 13 of the two wheeled running mechanisms roll on the upper and lower sides of the photovoltaic module frame respectively.

[0026] The bolt with a compression spring provides a tightening force to the photovoltaic component for the limiting wheel 13, and can also be extended and retracted within a certain range. The force of the compression spring and the bolt and nut gives the mechanism an antagonistic force, making the structure more stable. The limiting wheel 13 can cope with the ups and downs of the photovoltaic panel boundary and improve the overall stability and safety of the device.

[0027] The surface of the walking wheel is provided with a driving wheel rubber bag 2, which further improves the performance of the device corresponding to the ups and downs of the photovoltaic panel. The driving wheel rubber bag 2 is provided with an anti-skid groove, which makes the walking wheel less likely to slip when walking on the surface of the photovoltaic module, effectively improving the accuracy of photovoltaic coating.
