Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figs. 1-4 In the embodiments of the utility model, a water supply and drainage filtering structure comprises a filter assembly 3 installed on the inner side of a shaft 1 and distributed below a well lid 2, the filter assembly 3 comprises a rectangular top frame 301, a C-shaped filter frame 302, a filter bottom plate 303, an inclined filter plate 306, an arc-shaped guide plate 307 and an inclined guide plate 308.

[0022] The C-shaped filter frame 302 is fixed to the bottom of the rectangular top frame 301, the C-shaped filter frame 302 is placed on the inner side of the shaft 1 through the limiting of the rectangular top frame 301, and the well lid 2 is placed on the top of the rectangular top frame 301.

[0023] The filter bottom plate 303 is rotationally connected to the bottom of the C-shaped filter frame 302 through a hinge, and the space formed by the filter bottom plate 303 and the C-shaped filter frame 302 is used for collecting solid impurities.

[0024] The inclined filter plate 306 and the inclined guide plate 308 are symmetrically fixed to the inner walls of the rectangular top frame 301 on both sides and extend to the inner side of the C-shaped filter frame 302, the arc-shaped guide plate 307 is fixed to the bottom end of the inclined filter plate 306, the bottom end of the inclined filter plate 306 is inclined towards the upper surface of the inclined guide plate 308, the bottom end of the inclined guide plate 308 is inclined towards the inner side of the arc-shaped guide plate 307, the inclined surfaces of the inclined filter plate 306 and the inclined guide plate 308 are used for enabling impurities to better slide and fall to the bottom of the C-shaped filter frame 302, and the channel formed by the inclined filter plate 306, the arc-shaped guide plate 307 and the inclined guide plate 308 is used for avoiding that leaves float to the area of the inclined filter plate 306 when water accumulates in the C-shaped filter frame 302.

[0025] The inclined filter plate 306 and the arc-shaped guide plate 307 block the recessed parts of the side surfaces of the C-shaped filter frame 302, filter holes are formed in the periphery of the C-shaped filter frame 302, the filter bottom plate 303 and the inclined filter plate 306, and the filter holes have the same diameter.

[0026] The top of the shaft 1 is shaped with a rectangular recess for placing the rectangular top frame 301 and the cover 2, and the outer wall size of the C-shaped filter frame 302 is smaller than the inner wall size of the shaft 1.

[0027] In this embodiment: when the filter assembly 3 is placed inside the shaft 1, the cover 2 is closed on the top of the rectangular top frame 301, and in rainy weather, rainwater and impurities (such as leaves and stones) can fall into the C-shaped filter frame 302 through the through hole on the cover 2. At this time, the rainwater can contact the inclined filter plate 306 and the inclined guide plate 308, which are in an inclined state. Therefore, the rainwater can flow along the inclined surface of the inclined filter plate 306 and the inclined guide plate 308 and drive the impurities to slide down. Part of the rainwater on the inclined filter plate 306 can flow out to the outside of the C-shaped filter frame 302 through the filter hole on the inclined filter plate 306, that is, into the shaft, and the preliminary drainage is completed at this time.

[0028] The rainwater and impurities flowing along the surface of the inclined filter plate 306 will fall on the inclined guide plate 308 and slide into the arc-shaped guide plate 307. The impurities will quickly slide to the bottom area of the C-shaped filter frame 302 under the scouring of the rainwater and will be finally intercepted by the filter bottom plate 303 (it should be noted that the inclined guide plate 308 and the arc-shaped guide plate 307 are not provided with filter holes, which is mainly to increase the sliding amount of rainwater, so as to increase the scouring force of rainwater on impurities, so that the impurities can be better scoured to the bottom area of the C-shaped filter frame 302). The rainwater is discharged through the filter holes on the C-shaped filter frame 302 and the filter bottom plate 303, achieving the effect of efficient drainage.

[0029] When the C-shaped filter frame 302 is filled with more impurities in the area below the inclined guide plate 308 and the arc-shaped guide plate 307, and the rainwater cannot be discharged in time, there is accumulated water in the C-shaped filter frame 302, and the liquid level of the accumulated water will rise above the positions of the arc-shaped guide plate 307 and the inclined guide plate 308. At this time, the channel composed of the inclined filter plate 306, the arc-shaped guide plate 307, and the inclined guide plate 308, which is similar to an “S”, can avoid the leaves in the area below the C-shaped filter frame 302 from floating to the area of the inclined filter plate 306, so that the area above the inclined guide plate 308 and the inclined filter plate 306 and the upper surface of the inclined filter plate 306 of the C-shaped filter frame 302 remain in a state with less impurities, so as to maintain a certain drainage capacity (it should be noted that the side surface of the C-shaped filter frame 302 in the area above the inclined guide plate 308 and the inclined filter plate 306 is also provided with filter holes), avoiding the situation that the rainwater cannot be discharged due to complete blockage.

[0030] Please refer to Figs. 1-4The second fixing cylinder 305 is welded and fixed on the side of the filter bottom plate 303 away from the hinge, the first fixing cylinder 304 is welded and fixed on the position corresponding to the second fixing cylinder 305 on the outer side of the C-shaped filter frame 302, the second fixing cylinder 305 is aligned with the first fixing cylinder 304 when the filter bottom plate 303 is closed, and the locking of the filter bottom plate 303 and the first fixing cylinder 304 is realized by the bolt penetrating through the second fixing cylinder 305 and the first fixing cylinder 304.

[0031] In the embodiment, the filter assembly 3 can be cleaned regularly according to the use environment during use, and the operation method is as follows:

[0032] Only the well lid 2 is opened, the filter assembly 3 is taken out from the shaft 1 as a whole, the bolt on the second fixing cylinder 305 and the first fixing cylinder 304 is removed, the filter bottom plate 303 is opened, and the impurities are poured out, so that the whole operation is simple and convenient.

[0033] Please refer to Fig. 2 、 Fig. 4 The reinforcing rib 309 is welded and fixed on the inner side of the middle part of the rectangular top frame 301, and the upper surface of the reinforcing rib 309 is flush with the upper surface of the rectangular top frame 301.
