A driving assembly is provided on the frame 2. When the driving assembly is in operation, the driving assembly can drive the movable plate 10 to move; the driving assembly includes a connecting spring 106, a screw rod 107 and a driving motor 108. The connecting springs 106 are evenly spaced and connected between the front side of the slide plate 105 and the inner side of the frame 2. The screw rod 107 is symmetrically connected to the front and rear sides of the frame 2 for rotation. The rear sides of the left and right screw rods 107 are driven by a synchronous belt assembly.

[0036] First, the device is placed at a designated location, and sunlight shines on the photovoltaic panel 3. The photovoltaic panel 3 absorbs the sunlight and converts it into electrical energy, thereby generating electricity. When it rains, rainwater falls on the photovoltaic panel 3, and the rainwater on the photovoltaic panel 3 flows into the frame 2. Since the bottom of the frame 2 is a left-right symmetrical slope, the rainwater flows to the left and right sides of the frame 2. The rainwater in the frame 2 flows into the drain pipe 6, and the water in the drain pipe 6 is discharged into the collection frame 81. The rainwater in the collection frame 81 is discharged into the bellows 82. The rainwater in the bellows 82 flows into the water inlet pipe 5 and contacts the water receiving rack 93. The rainwater drives the water receiving rack 93 to rotate, and the rotation of the water receiving rack 93 drives the rotating shaft 92 to rotate, and the rotating shaft 92 drives the rotating disk 94 to rotate. The sensor 95 senses the rotation speed of the rotating disk 94. As the water receiving frame 93 rotates, rainwater continues to flow and is discharged into the collection box 4 to be collected. Then the drive motor 108 is started to drive the left screw 107 to rotate forward. The left screw 107 drives the right screw 107 to rotate through the synchronous belt assembly. The left and right screws 107 rotate to drive the movable plate 10 to move forward. The movable plate 10 moves forward and drives the transparent film 102 to move forward through the guide plate 101. The transparent film 102 moves forward and drives the slide plate 105 to move backward. The connecting spring 106 is stretched. When the movable plate 10 moves forward to the maximum stroke, the drive motor 108 is turned off, and the movable plate 10 stops moving forward. At this time, the inclined surface of the movable plate 10 is located above the water collecting frame 103, and the transparent film 102 blocks the rainwater to prevent it from falling on the photovoltaic panel 3. The transparent film 102 does not affect the conversion efficiency of the photovoltaic panel 3, and the rainwater falls on the transparent film 102. The rainwater on the transparent film 102 flows into the water collecting frame 103 through the movable plate 10, and the rainwater in the water collecting frame 103 is discharged into the collecting frame 81 through the outlet pipe 104. When the sensor 95 detects that the rotation speed of the rotating disk 94 reaches the set maximum value, the sensor 95 controls the electric push rod 91 to start through the control module, and the telescopic rod of the electric push rod 91 is shortened to drive the rear side of the frame 2 to swing downward, and the rear side of the frame 2 swings downward to make the front side swing upward, which also makes the frame 2 swing into a horizontal state, and the frame 2 makes the photovoltaic panel 3 in a horizontal state. When the rainfall is heavy, the rainwater can be discharged to prevent residue, and at the same time, the front side of the frame 2 swings upward to also The L-shaped plate 8 drives the collecting frame 81 to swing upward. Due to the action of the connecting rod 83, the collecting frame 81 is always in a vertical state with the ground during the upward swing. When the amount of rainwater is small, a small amount of rainwater is discharged into the water inlet pipe 5, and the rotation speed of the water receiving frame 93 is reduced. The reduced rotation speed of the water receiving frame 93 also reduces the rotation speed of the rotating disk 94. The sensor 95 senses the reduced rotation speed of the rotating disk 94, and the sensor 95 controls the extension of the telescopic rod of the electric push rod 91 through the control module, so that the frame 2 swings back to an inclined setting, and the rainwater can flow downward better. This is repeated, and the inclination angle of the photovoltaic panel 3 can be automatically adjusted according to the amount of rain on rainy days to prevent the coverage and accumulation of rainwater, thereby improving the conversion efficiency of the photovoltaic panel 3. When the rain stops,The driving motor 108 is started to drive the screw 107 to reverse, and the screw 107 drives the movable plate 10 to move backward and reset. The movable plate 10 moves backward so that the transparent film 102 moves backward and resets. The transparent film 102 is loosened. Due to the action of the connecting spring 106, the slide plate 105 moves forward and resets, and drives the transparent film 102 to move forward and reset through the guide plate 101.

[0037] See also Figure 9-11 As shown, the photovoltaic device with automatic tilt adjustment function in rainy days also includes a cleaning component installed between the frame 2 and the collection box 4, the cleaning component includes a sponge roller 11, a circulation pipe 111, a water pump 112, a guide frame 113, a rotating component and a rotating pipe 116, the lower part of the movable plate 10 is horizontally rotatably connected with the rotating pipe 116, the middle part of the outer side of the rotating pipe 116 is fixedly sleeved with the sponge roller 11, when the sponge roller 11 moves to contact the photovoltaic panel 3, the sponge roller 11 can remove impurities attached to the photovoltaic panel 3, the water pump 112 is installed on the left front side of the collection box 4, the water inlet end of the water pump 112 is located in the collection box 4, and the water outlet end of the water pump 112 is located in the collection box 4.

[0038] When the movable plate 10 moves forward, the movable plate 10 drives the rotating tube 116 to move forward, the rotating tube 116 drives the sponge roller 11 and the spur gear 115 to move forward, the spur gear 115 moves forward and rotates through the rack 114, the spur gear 115 rotates and drives the rotating tube 116 to rotate, the rotating tube 116 drives the sponge roller 11 to rotate, the sponge roller 11 rotates and moves forward to contact the photovoltaic panel 3, and at the same time the rotating tube 116 also drives the circulation tube 111 to move forward, the circulation tube 111 is relaxed, and the guide frame 113 supports and guides the circulation tube 111. At this time, the water pump 112 is started, and the water pump 112 collects the rainwater in the collection box 4. The rainwater in the circulation pipe 111 is drawn into the rotating pipe 116, and the rainwater in the rotating pipe 116 is discharged and infiltrated into the sponge roller 11. The sponge roller 11 removes the impurities attached to the photovoltaic panel 3 through the rainwater. The removed impurities and rainwater are discharged into the collection frame 81 through the drainage pipe 6, and then discharged back to the collection box 4 for use. When the movable plate 10 moves forward to the maximum stroke, the movable plate 10 stops moving forward, the movable plate 10 stops driving the rotating pipe 116 to move forward, the sponge roller 11 stops moving forward, and the rotating pipe 116 stops driving the spur gear 115 to move forward, and the spur gear 115 stops rotating. When the movable plate 10 moves backward to reset, the movable plate 10 drives the sponge roller 11 to move backward to reset through the rotating pipe 116, and the water pump 112 is turned off. In this way, a large amount of impurities attached to the photovoltaic panel 3 can be prevented from affecting the absorption and conversion of sunlight, thereby ensuring the use effect of the photovoltaic panel 3.

The pull rod 13 is fixed to the front side of the filter plate 12.

[0040] When the rainwater is discharged back into the collection box 4, the rainwater contacts the filter plate 12, and the filter plate 12 filters the impurities in the rainwater. The rainwater after filtering the impurities continues to flow into the bottom of the collection box 4. After the filter plate 12 has been used for a long time, the pull rod 13 is pulled to drive the filter plate 12 to move forward and disengage from the collection box 4, and the impurities on the filter plate 12 are removed. After the impurities on the filter plate 12 are removed, the filter plate 12 is put back into the collection box 4.
