On the basis of the above, a water blocking part 2024 is convexly arranged on one side surface of the filter screen member 202 facing the water inlet pipe 201, and the water blocking part 2024 is close to the notch of the material placing groove, so that the difficulty of pushing and sweeping materials in the material placing groove to flow back and cover the blocking filter holes 2021 is increased.
That is, as shown in fig. 3, the water blocking portion 2024 is disposed close to the notch of the first stock chest 2022; or as shown in fig. 4, the water blocking portion 2024 is disposed close to the notch of the second stock chest 2023.
At this time, in order to push the material on one side of the filter element 202 facing the water inlet pipe 201 to the material placing groove during push-sweeping, as shown in fig. 3 and fig. 4, the material sweeping element 203 includes a rigid connection portion 2031 fixedly connected with the material sweeping element driving device, and a flexible push-sweeping portion 2032 contacting with the filter element 202, the push-sweeping portion 2032 is made of a material such as a brush or silica gel, and the size of the push-sweeping portion 2032 is adapted to the size of the water blocking portion 2024.
Further, considering that the material accommodating groove is a main accommodating structure for dirt accumulation at this time, the upper end surface of the water tank 2 is adapted to be provided with a cleaning opening 204 of the material accommodating groove, specifically, as shown in fig. 3, the upper end surface of the water tank 2 is adapted to be provided with a cleaning opening 204 of the first material accommodating groove 2022, or as shown in fig. 4, the upper end surface of the water tank 2 is adapted to be provided with a cleaning opening 204 of the second material accommodating groove 2023. And a blocking cover 205 for blocking the cleaning port 204 is detachably connected to the water tank 2 by using, for example, screws. Through dismantling shutoff apron 205, can be more convenient, clear up piled up dirt more pertinently.
Still further, considering the use of a severe dust environment, as shown in fig. 5, the bottom of the water collecting tank 301 is provided with a water guiding port 3011, the water guiding port 3011 is communicated with the water inlet pipe 201, and the bottom surface of the water collecting tank 301 includes a mud blocking inclined surface 3012 which is obliquely arranged to guide the material to flow from the water guiding port 3011 to a direction far away from the water guiding port 3011. Thus, when the surface of the photovoltaic power generation panel 1 is washed, and the liquid with sediment flows into the water collecting tank 301 after washing, the heavier sediment flows away from the water guide port 3011 under the diversion effect of the mud blocking inclined plane 3012, so that the sediment is prevented from directly flowing into the water guide port 3011 and entering the water tank 2 along the water guide port 3011 to form a covering blockage on the filter holes 2021 of the filter screen member 202, and when the liquid overflows to the height of the water guide port 3011, the liquid can still enter the water tank 2 from the water guide port 3011 for recycling. The amount of sediment entering the tank 2 from the water guide 3011 is greatly reduced.
On the basis of the above, the pore diameter of the filter element 202 may gradually increase in the direction from the side of the filter element 202 facing the water inlet pipe 201 to the side of the filter element 202 facing away from the water inlet pipe 201. Thus, when some impurity particles with the similar size to the filter holes 2021 enter the filter holes 2021, the impurity particles are not blocked in the filter holes 2021 to cause the filter holes 2021 to be blocked, but only enter the filter holes 2021 as long as the filter size requirement can be met, and can smoothly flow downwards to the bottom of the water tank 2 along with the liquid from the filter holes 2021.
