Description

Technical Field

[0001] This utility model relates to the field of wind resistance technology, and in particular to a device for improving the wind resistance of photovoltaic sweepers. Background Technology

[0002] Currently, due to air pollution and the fact that photovoltaic power stations are located in desert areas, the surface of their solar panels is covered by sand and dust, which significantly reduces the power generation efficiency of the batteries. If manual cleaning is used, it is not only inefficient but also costly. In some places, manual cleaning is also inconvenient because photovoltaic panels are usually set in relatively open locations, so photovoltaic panel cleaning machines are easily affected by strong winds during use.

[0003] Chinese Patent CN219420707U discloses a photovoltaic cleaning machine, including a photovoltaic module and a cleaning machine body. The cleaning machine body has a motor, a cleaning brush, and multiple drive wheels inside its cavity. The cleaning brush and drive wheels are driven to rotate by the motor. The drive wheels press against the upper side of the photovoltaic module. Connecting frames are provided between both sides of the cleaning machine body and both sides of the photovoltaic module. Wheel frames are provided on both sides of the connecting frames. A limiting wheel is rotatably installed inside each wheel frame. A pressure rod is provided at the outer end of each wheel frame. A connecting shaft is provided in the middle of each wheel frame. A pressure sensor is provided inside the wheel frame and between the pressure rod. An intelligent controller is provided on the upper side of the cleaning machine body. This application can prevent the photovoltaic cleaning machine from tilting during cleaning, thereby preventing the cleaning machine from falling off and causing malfunctions, and ensuring the smooth progress of the cleaning process.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: When the above-mentioned device is used, the surface of the photovoltaic panel is cleaned by a cleaning machine. However, the device uses a fixed limiting wheel structure to limit the cleaning machine, which can easily cause the device to tilt in strong winds. Utility Model Content

[0031] The following is combined with Figure 1-4 The present invention will be described in further detail below.

[0032] Example 1

[0033] like Figure 1-Figure 4 As shown, in order to solve the existing problems, this utility model discloses a device to improve the wind resistance of a photovoltaic sweeper, including a connecting plate 3, a connecting bracket 4 slidably connected to the side of the connecting plate 3, a sweeper 2 connected to the connecting bracket 4, a photovoltaic panel 1 slidably connected to the sweeper 2, a locking bracket 13 connected to the side of the photovoltaic panel 1, an electric telescopic column 12 connected to the side of the sweeper 2, the electric telescopic column 12 contacting the locking bracket 13, a limiting rod 14 connected to the side of the photovoltaic panel 1, the limiting rod 14 contacting the sweeper 2, a rotation damping component 6 connected to the connecting plate 3, a rotation knob 5 rotatably connected to the rotation damping component 6, a gear 10 connected to the rotation knob 5 through a rotating shaft, a rack 11 meshing with the gear 10, the rack 11 connected to the connecting bracket 4, and a stop component 9 connected to the connecting plate 3.

[0034] The abutting component 9 includes a rotating support bracket 908 connected to the connecting plate 3. The rotating support bracket 908 is rotatably connected to an elastic telescopic rod 907. The telescopic end of the elastic telescopic rod 907 is connected to a rotating connector 906. The rotating connector 906 is rotatably connected to a connecting rod 904. The connecting plate 3 is provided with a limiting groove 902. The inner wall of the limiting groove 902 is provided with a protrusion. The connecting rod 904 is connected to a rotating bracket 901. The outer side of the rotating bracket 901 is provided with a transmission groove 903. The inner wall of the transmission groove 903 is slidably connected to the protrusion. The bottom of the rotating bracket 901 is rotatably connected to a roller 905.

[0035] The connecting bracket 4 is provided with a plurality of equally spaced positioning holes 7, and the side of the connecting bracket 4 is rotatably connected to a limit wheel 8.

[0036] The connecting plate 3 is provided with a through hole, and the rotation damping component 6 is in the shape of a ring. The rotation damping component 6 is connected to the rotation damping of the outer arc surface of the rotating shaft provided on the rotating knob 5.

[0037] The connecting plate 3 is provided with two connecting brackets 4, and racks 11 are symmetrically arranged on both sides of the gear 10. The racks 11 are staggered on both sides of the gear 10 and connected to the connecting brackets 4.

[0038] The specific working principle is as follows: By installing this device on the side of the sweeper 2, the working stability of the sweeper 2 in strong wind environment can be improved. Compared with traditional devices, this device is easier to install and adopts an elastic buffer structure to buffer the lateral tension generated by strong wind, reducing the risk of the device breaking.

[0039] In actual use, this device is connected to the sweeper 2 via the connecting bracket 4. By rotating the knob 5, the gear 10 can be rotated, and the spacing of the connecting bracket 4 can be controlled by the rack 11.

[0040] After the connecting plate 3 is installed, the limiting wheel 8 contacts the side of the photovoltaic panel 1, and the roller 905 also contacts the side of the photovoltaic panel 1. When strong winds occur, the connecting plate 3 tilts due to the influence of strong lateral winds. At this time, the rotating bracket 901 slides relative to the inner wall of the limiting groove 902, thereby driving multiple electric telescopic rods 907 to extend and retract. The combination of the rotating bracket 901 and the limiting groove 902 can realize the elastic sliding of the roller 905 while also allowing the roller 905 to tilt and rotate simultaneously, thus providing a buffering effect against strong winds in all directions. The symmetrical structure of the electric telescopic rods 907 can effectively improve the central symmetrical elastic buffering effect of this device. At the same time, the symmetrical electric telescopic rods 907 can facilitate the automatic reset of the rotating bracket 901 after the strong winds disappear.

[0043] The locking bracket 13 can achieve the locking stability of this device, and the bolt structure can effectively improve the combined connection stability of this device.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
