[0027] Advantageously, a second filter screen 36 is symmetrically and fixedly disposed on the bottom end surface of the mounting frame 12 , and both ends of the lifting rod 14 are close to the second filter screen 36 .

[0028] Advantageously, the telescopic assembly includes a first connecting groove 15 opened at both ends of the fixed rod 13, and a second flip rod 19 that can rotate is symmetrically provided in the first connecting groove 15 on each side. The end surface of the lifting rod 14 is symmetrically provided with a second connecting groove 16, and a first flip rod 17 is rotatably installed in the second connecting groove 16. The first flip rod 17 is provided with a slide groove 18, and the end of the second flip rod 19 extends into the slide groove 18 and is slidably connected to the slide groove 18.

[0029] Advantageously, the openings of the slide grooves 18 on both sides of the lifting rod 14 are opposite to each other, and the openings of the slide grooves 18 face toward a side away from the rotation center of the first flip rod 17 .

[0030] Advantageously, a storage plate 20 is fixedly installed between the slide grooves 18 on both sides, and a storage cavity 21 is opened on the storage plate 20. The storage cavity 21 is connected to the slide grooves 18 on both sides. A first filter screen 22 is slidably provided in the storage cavity 21, and the first filter screen 22 is fixedly connected to the second flip rods 19 on both sides thereof.

[0031] Advantageously, the cleaning mechanism comprises an electric slide rail 30 symmetrically arranged on the top side of the sewage treatment tank 11, and support rods 29 are symmetrically and fixedly installed at the ends of both sides of the electric slide rail 30. The bottom end of the support rod 29 is fixedly connected to the top side of the sewage treatment tank 11, and an electric slider 31 is slidably installed on the electric slide rail 30, and a second hydraulic telescopic rod 32 is fixedly installed on the bottom end face of the electric slider 31.

[0032] Advantageously, the second hydraulic telescopic rod 32 is parallel to the inner wall of the sewage treatment tank 11 toward which the collecting bucket 34 opens.

[0033] Advantageously, a connecting rod 33 is fixedly mounted at the end of the telescopic portion of the second hydraulic telescopic rod 32 , and the end of the connecting rod 33 is fixedly connected to the top end surface of the collecting bucket 34 .

[0034] Method of use of the present invention:

[0035] In the initial state: the collecting bucket 34 is located at the extreme position in the sewage treatment tank 11 on the opposite side of its opening, the first hydraulic telescopic rod 26 is in an extended state, the height position of the lifting rod 14 is lower than the fixed rod 13, the second flip rod 19 and the first filter screen 22 are both in an extended state, and the storage plate 20 and the first filter screen 22 on both sides of the same lifting rod 14 form a V shape.

[0036] During normal use, domestic sewage is discharged from the top side of the sewage treatment tank 11. After the sewage enters the sewage treatment tank 11, it contacts the separation mechanism. During the flow of sewage, leaves, plastic bags, etc. mixed in the sewage will move with the sewage. In this process, leaves, plastic bags, etc. that enter the V-shaped cavity area between the receiving plate 20 and the first filter screen 22 are pierced and hooked by the first hook 23 and the second hook 24 under the impact of subsequent water flow. Branches in the sewage will also be intercepted in the V-shaped cavity area. Due to the top side arc surface of the fixing rod 13 and the lifting rod 14, the pierced and hooked leaves and plastic bags cannot be tightly attached to the fixing rod 13 or the lifting rod 14, and the sewage can pass through the first filter screen 22 and the second filter screen 36 and enter the bottom side of the separation mechanism in the sewage treatment tank 11.

[0037] During use, the cleaning mechanism is turned on at regular intervals. When the cleaning mechanism is turned on, the external control system first controls the first hydraulic telescopic rod 26 to retract, so that the first hydraulic telescopic rod 26 drives the sliding rod 27 to rise, and the push rod 28 drives each lifting rod 14 to rise together, so that the second hook thorn 24 on the top side of the lifting rod 14 is at the same height as the first hook thorn 23. During this process, the first filter screen 22 is gradually retracted into the storage chamber 21, so that the external control system then controls the electric slider 31 to start, and the electric slider 31 drives the second hydraulic telescopic rod 32, the connecting rod 33 and the collecting bucket 34 to move. During the movement, the shovel plate 35 pierces the first hook thorn 23 and the second hook thorn 24 and hooks them. The leaves and plastic bags are scooped up, so that the leaves and plastic bags are separated from the first hook 23 and the second hook 24 and collected in the collecting bucket 34, and the branches intercepted by the separation mechanism are also pushed to move by the collecting bucket 34. When the shovel plate 35 contacts the inner wall of the sewage treatment tank 11, that is, the electric slider 31 and the collecting bucket 34 move to the extreme position, the second hydraulic telescopic rod 32 contracts and drives the collecting bucket 34 to tilt upward, so that the shovel plate 35 and the collecting bucket 34 are closely attached to the inner wall of the sewage treatment tank 11 and move outside the sewage treatment tank 11. After the collecting bucket 34 stops, the leaves, plastic bags, branches, etc. collected in the collecting bucket 34 are dumped on the ground outside the sewage treatment tank 11, waiting for the staff to clean them up.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
