The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

Figure 2 It is a structural schematic diagram of the elastic component and the cleaning roller of the utility model. Figure 3 It is a structural schematic diagram of the movable frame 104 and the bearing plate 107 of the utility model.

[0020] The photovoltaic assembly for photovoltaic power generation of the utility model includes a support frame 101, a photovoltaic panel body 102, a guide rail 103, a movable frame 104, a telescopic rod 105, a spring 106, a bearing plate 107, a mounting seat 108, a cleaning rod 109, a first motor 110, a screw 111, a second motor 112, a limit groove 113, and a protrusion 114, which solves the problem that the prior art is difficult to remove some sticky dirt or fine sand and dust accumulated for a long time due to cleaning by vacuuming, and the cleaning ability is poor. It is understandable that the above solution can also be used to improve the cleaning effect.

[0021] In this embodiment, the support frame 101 and the photovoltaic panel body 102 are both existing technologies. The cleaning component is installed on the support frame 101, so that sticky dirt, such as bird droppings, can be removed, which solves the problem that the existing technology is difficult to remove some sticky dirt or long-term accumulated fine dust due to cleaning by vacuuming, and the cleaning ability is poor.

[0022] The guide rail 103 is fixedly connected to the support frame 101 and is located on a side of the support frame 101 close to the photovoltaic panel body 102. The movable frame 104 is slidably connected to the guide rail 103 and is located on a side of the guide rail 103 away from the support frame 101. The bearing plate 107 is connected to the movable frame 104 through the elastic member. The elastic member is installed on the movable frame 104 and supports the bearing plate 107. The mounting seat 108 is fixed to the bearing plate 107. The cleaning roller is mounted on the mounting seat 108, and the driving member drives the movable frame 104 to move. The guide rails 103 are arranged on both sides of the photovoltaic panel body 102 along the length direction of the support frame 101. The movable frame 104 is U-shaped and has a slide groove matching the guide rail 103. The movable frame 104 is connected to the guide rail 103 through the slide groove and can slide freely along the guide rail 103. The supporting plate 107 is a rectangular plate, which is located in the movable frame 104. The supporting plate 107 is elastically supported by the elastic member. There are two mounting seats 108 for mounting the cleaning roller, so that the cleaning roller is stably supported. The cleaning roller is used to clean the surface of the photovoltaic panel body 102. Under the action of the elastic member, it can be ensured that the cleaning roller acts on the photovoltaic panel body 102 to avoid the wear of the cleaning roller and the gap between the photovoltaic panel body 102, thereby affecting the cleaning effect. The driving member is used to drive the movable frame 104 to move, and the movement of the movable frame 104 drives the cleaning roller to move, so as to clean the entire photovoltaic panel body 102. The cleaning roller is in direct contact with the photovoltaic panel body 102 for cleaning, thereby improving the cleaning effect, and solving the problem that the prior art is difficult to remove some sticky dirt or long-term accumulated fine sand and dust due to vacuuming, and the cleaning ability is poor.

[0023] Secondly, the telescopic rod 105 is fixedly connected to the movable frame 104, and the bearing plate 107 is fixedly installed on the end of the telescopic rod 105; the spring 106 is sleeved on the outside of the telescopic rod 105 and is located between the movable frame 104 and the bearing plate 107.

The bearing plate 107 is fixedly connected to the telescopic ends of the two telescopic rods 105. Through the telescopic rod 105, the bearing plate 107 can be vertically extended and retracted. The spring 106 is in a compressed state. Through the cooperation of the telescopic rod 105 and the spring 106, the bearing plate 107 is elastically supported.

[0024] At the same time, the cleaning rod 109 is rotatably connected to the mounting seat 108 and contacts the photovoltaic panel body 102; the first motor 110 is installed on the mounting seat 108, and the output shaft of the first motor 110 is fixedly connected to the cleaning rod 109, and the cleaning rod 109 includes a shaft and bristles, and the bristles are arranged on the outer peripheral side of the shaft, and the bristles are in contact with the surface of the photovoltaic panel body 102. A bearing is arranged in the mounting seat 108, and the shaft passes through the mounting seat 108 and is fixedly connected to the inner ring of the bearing. The first motor 110 is fixed to the side of one of the mounting seats 108 by bolts, and is used to drive the cleaning rod 109 to rotate. The cleaning rod 109 is driven to rotate by the first motor 110, so that the cleaning rod 109 sweeps the surface of the photovoltaic panel body 102, thereby achieving cleaning.

[0025] In addition, the screw 111 is rotatably mounted on the support frame 101 and is threadedly connected to the movable frame 104; the second motor 112 is mounted on the support frame 101, and the output shaft of the second motor 112 is fixedly connected to the screw 111. The screw 111 is mounted on the support frame 101 through a bearing bracket, so that the screw 111 can be supported and rotated at the same time. A threaded through hole is provided on the movable frame 104, and the screw 111 passes through the threaded through hole and is threadedly connected to the movable frame 104. The second motor 112 is fixed to the support frame 101 by bolts to drive the screw 111 to rotate. The second motor 112 is provided with a matching controller. Through the controller, the second motor 112 can be operated in a set direction, speed, and time. The screw 111 is driven to rotate by the second motor 112, thereby driving the movable frame 104 to move along the guide rail 103.

[0026] Finally, the limiting groove 113 is located on one side of the movable frame 104 close to the supporting plate 107; the protrusion 114 cooperates with the movable frame 104, and the limiting groove 113 is a T-shaped groove, which is vertically opened on the inner wall of the movable frame 104, and the protrusion 114 is located on both sides of the supporting plate 107 and extends into the limiting groove 113. Through the cooperation between the protrusion 114 and the limiting groove 113, the supporting plate 107 is limited, the shaking of the supporting plate 107 is reduced, and the stability is improved.

[0027] In this embodiment, during cleaning, the first motor 110 is actuated to drive the cleaning rod 109 to rotate, and the cleaning rod 109 sweeps and cleans the surface of the photovoltaic panel body 102. At the same time, the second motor 112 is actuated, and the second motor 112 performs regular forward and reverse rotation under the action of the controller, and under the transmission of the screw 111, forces the movable frame 104 to reciprocate along the guide rail 103, thereby achieving overall cleaning of the surface of the photovoltaic panel body 102. The present application directly sweeps and brushes the surface of the photovoltaic panel body 102 through the rotation of the cleaning rod 109, thereby improving the cleaning ability of dirt, and solving the problem that the prior art is difficult to remove some highly sticky dirt or long-term accumulated fine sand and dust due to cleaning by vacuuming, and has poor cleaning ability.
