[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: an auxiliary device for preventing dust and water from a photovoltaic module, comprising an auxiliary bracket 1 and a waterproof and dustproof mechanism 3, fixing mechanisms 2 are arranged at both ends of the auxiliary bracket 1, and a waterproof and dustproof mechanism 3 is arranged on one side of the surface of the auxiliary bracket 1;

[0021] The waterproof and dustproof mechanism 3 includes a waterproof plate 301, a support base 302, a movable groove 303, a screw rod 304, a servo motor 305, a slider 306, a mounting plate 307, a brush 308 and a cleaning block 309. The waterproof plate 301 is installed inside the auxiliary bracket 1, and one side of the surface of the auxiliary bracket 1 is fixedly connected to the support base 302, and one side of the surface of the support base 302 is provided with a movable groove 303. The movable groove 303 is provided with a screw rod 304 inside. One end of the screw rod 304 is connected to the servo motor 305. The surface of the screw rod 304 is sleeved with a slider 306, and one end of the slider 306 is fixedly connected to the mounting plate 307. The bottom surface of the mounting plate 307 is installed with a brush 308, and the bottom surface of the mounting plate 307 is installed with a cleaning block 309. The rod 304, servo motor 305, slider 306, mounting plate 307, brush 308 and cleaning block 309 are arranged. When in use, the transparent glass waterproof board 301 can waterproof the photovoltaic module and prevent dust from falling on the photovoltaic module. When there are stains and impurities on the waterproof board 301, the servo motor 305 can be turned on. At this time, the servo motor 305 drives the screw rod 304 to rotate inside the movable groove 303. Since the slider 306 is embedded in the movable groove 303 and the threaded sleeve is arranged on the surface of the screw rod 304, when the screw rod 304 rotates, the slider 306 moves along the screw rod 304 inside the movable groove 303. At this time, the slider 306 drives the mounting plate 307 to move on the surface of the waterproof board 301, so that the brush 308 and the cleaning block 309 clean and remove the dust and impurities on the waterproof board 301.

[0022] Furthermore, the waterproof plate 301 is a transparent glass plate, and the servo motor 305 is installed at one end of the support base 302. Through the setting of the servo motor 305, when in use, the servo motor 305 can drive the screw rod 304 to rotate inside the movable groove 303.

[0023] Furthermore, the slider 306 is embedded in the movable groove 303, and the cross-sectional size of the slider 306 is consistent with the cross-sectional size of the movable groove 303. The slider 306 is threadedly sleeved on the surface of the screw rod 304. Through the setting of the slider 306, the screw rod 304 rotates inside the movable groove 303 so that the slider 306 can move along the screw rod 304 inside the movable groove 303, thereby driving the mounting plate 307 to move.

[0024] Furthermore, one end of the brush 308 is in contact with the waterproof board 301, and one end of the cleaning block 309 is in contact with the waterproof board 301. The cleaning block 309 is made of sponge material. Through the setting of the brush 308 and the cleaning block 309, when in use, the brush 308 and the cleaning block 309 can clean the waterproof board 301 while following the movement of the mounting plate 307.

[0025] Furthermore, the fixing mechanism 2 includes a fixed base 201, a threaded hole 202, a screw 203, a rotating knob 204, a limit block 205, a clamping block 206, a limit hole 207, a limit groove 208 and a protective sheet 209. Both ends of the auxiliary bracket 1 are fixedly connected to the fixed base 201. A threaded hole 202 is provided on one side of the surface of the fixed base 201. The internal thread of the threaded hole 202 passes through the screw 203. One end of the screw 203 is fixedly connected to the rotating knob 204. The other end of the screw 203 is fixedly connected to the limit block 205. One end of the screw 203 passes through the clamping block 206. A limit hole 207 is provided on one side of the surface of the clamping block 206. A limit groove 208 is provided inside the clamping block 206. A protective sheet 209 is bonded to one side of the surface of the clamping block 206. 202, screw 203, rotating knob 204, limit block 205, clamping block 206, limit hole 207, limit groove 208 and protective sheet 209 are arranged. When the auxiliary bracket 1 needs to be installed on the photovoltaic module, the edge of the photovoltaic module can be embedded in the inside of the fixed base 201, and then the rotating knob 204 is rotated. At this time, the rotating knob 204 drives the screw 203 to rotate. Since the screw 203 passes through the fixed base 201 through the threaded hole 202, the screw 203 drives the limit block 205 to move. Since the limit block 205 is embedded in the inside of the clamping block 206 through the limit groove 208, the movement of the limit block 205 drives the clamping block 206 to move. At this time, the clamping block 206 and the fixed base 201 fix the auxiliary bracket 1 on the photovoltaic module, and the protective sheet 209 can prevent the photovoltaic module from being damaged when being clamped.

[0026] Furthermore, the clamping block 206 is arranged inside the fixed base 201, and the limit block 205 is embedded in the limit groove 208. Through the setting of the limit block 205, when in use, the limit block 205 can drive the clamping block 206 to move when following the movement of the screw rod 203, and at the same time does not change the direction of the clamping block 206.

[0027] Furthermore, one end of the screw rod 203 passes through the limiting hole 207, and the protective sheet 209 is made of rubber. Through the setting of the protective sheet 209, the protective sheet 209 can prevent the photovoltaic component from being damaged when being clamped, and at the same time increase the friction between the clamping block 206 and the photovoltaic component.

[0028] Working principle: When the auxiliary bracket 1 needs to be installed on the photovoltaic module, the edge of the photovoltaic module can be embedded in the inside of the fixed base 201, and then the rotating knob 204 is turned. At this time, the rotating knob 204 drives the screw 203 to rotate. Since the screw 203 passes through the fixed base 201 through the threaded hole 202, the screw 203 drives the limit block 205 to move. Since the limit block 205 is embedded in the inside of the clamping block 206 through the limit groove 208, the movement of the limit block 205 drives the clamping block 206 to move. At this time, the clamping block 206 and the fixed base 201 fix the auxiliary bracket 1 on the photovoltaic module, and the protective sheet 209 can prevent the photovoltaic module from being damaged when being clamped. The transparent glass waterproof board 301 can waterproof the photovoltaic module and prevent dust from falling on the photovoltaic module. When there are stains and impurities on the waterproof board 301, the servo motor 305 can be turned on. At this time, the servo motor 305 drives the screw rod 304 to rotate inside the movable groove 303. Since the slider 306 is embedded in the movable groove 303 and the threaded sleeve is arranged on the surface of the screw rod 304, when the screw rod 304 rotates, the slider 306 moves along the screw rod 304 inside the movable groove 303. At this time, the slider 306 drives the mounting plate 307 to move on the surface of the waterproof board 301, so that the brush 308 and the cleaning block 309 clean and remove the dust and impurities on the waterproof board 301.
