[0021] The manhole cover 3 can seal the top of the shell 1. The cooperation between the mounting ring 31 and the top groove of the shell 1 ensures the stability of the manhole cover 3 after being installed on the shell 1. The filter barrel 2 is used to filter the debris carried in the sewage. The water pipe 11 allows the sewage to circulate inside the shell 1. The water pipe 11 located above allows the sewage to enter the shell 1. The water pipe 11 located below allows the sewage filtered by the filter barrel 2 to be discharged from the shell 1. The installation method of the filter screen 21 is convenient for the user to disassemble the filter screen 21. When the user cleans the debris filtered out of the filter barrel 2, the user releases the fixing block 22 on the filter screen 21. The filter screen 21 leaves the filter barrel 2 under the action of gravity, and the debris in the filter barrel 2 leaves the filter screen 21 together with the filter screen 21, which is convenient for the user to clean the debris. The side wall of the fixing block 22 is provided with a groove with a cross plate, which is convenient for the user to move the fixing block 22. When the user disassembles the filter barrel 2, the user installs the connecting rod 5 on the fixing frame 41. The shape of the connecting rod 5 ensures that both ends of the connecting rod 5 can enter the fixing frame 41 at the same time. The shape of the supporting rod of the connecting rod 5 ensures that the connecting rod 5 will not be hindered by the blocking block 42 during the process of entering the fixing frame 41. When the user installs the connecting rod 5 to the fixing frame 41, the blocking block 42 will push the blocking block 51, and the blocking block 51 enters the moving groove 52 under the pushing of the blocking block 42, ensuring that the connecting rod 5 will not be hindered during the installation of the fixing frame 41. After the blocking block 51 leaves the blocking block 42, the blocking block 51 returns to its original position under the action of the torsion spring shaft, and the connecting rod 5 passes through the blocking block. The block 51 and the blocking block 42 are fixed on the fixing frame 41, so that the user can move the filter barrel 2 out of the shell 1 through the connecting rod 5. By setting symmetrical moving grooves 52 on the supporting rods of the connecting rod 5, the stability of the connecting rod 5 after being installed on the fixing frame 41 is guaranteed. The sealing plate 43 can seal the top opening of the fixing frame 41 to prevent debris carried in the sewage from entering the fixing frame 41 during the use of the device, and to prevent the user from being hindered when inserting the connecting rod 5 into the fixing frame 41. The shape of the storage groove 44 ensures that the fixing frame 41 will not hinder the rotation of the sealing plate 43. The sealing plate 43 is installed on the torsion spring shaft. After the connecting rod 5 leaves the fixing frame 41, the sealing plate 43 can quickly return to its original position, ensuring the working effect of the sealing plate 43, unlocking the frame 41. 5 is used to release the cooperation between the blocking block 42 and the stopper 51. The inner wall shape of the unlocking frame 45 is matched with the support rod of the connecting rod 5. When the user pushes the unlocking frame 45 upward, the unlocking frame 45 will push the fixed frame 41 into the blocking block 42, thereby releasing the cooperation between the blocking block 42 and the stopper 51, so that the user can pull the connecting rod 5 out of the fixed frame 41. The side wall of the unlocking frame 45 is provided with a protrusion to ensure the stability of the unlocking frame 45 after being installed on the fixed frame 41. The side wall protrusion of the unlocking frame 45 can also prevent the unlocking frame 45 from being taken away from the fixed frame 41 by the connecting rod 5. The distance between the blocking block 42 and the bottom of the fixed frame 41 is greater than the distance between the stopper 51 and the bottom of the connecting rod 5, so as to prevent the blocking block 42 from hindering the unlocking frame 45 from pushing the stopper 51.A detachable cross bar is provided on the top of the connecting rod 5, and the side wall of the cross bar is raised to facilitate the user to push the unlocking frame 45.

[0022] Specifically, an arc block 53 is provided on the side wall of the stopper 51 , a groove matching with the arc block 53 is provided on the side wall of the movable groove 52 , and the center of the arc block 53 overlaps with the center of the torsion spring shaft on the stopper 51 .

[0023] The cooperation between the arc block 53 and the side wall groove of the movable groove 52 ensures the stability of the block 51 during the rotation process. The cooperation between the arc block 53 and the side wall groove of the movable groove 52 also plays a blocking role, reducing the force applied to the torsion spring shaft of the block 51 when the user moves the filter barrel 2, thereby ensuring the stability of the block 51. The shape of the arc block 53 ensures that the rotation of the block 51 will not be hindered.

[0024] Specifically, a baffle 54 is provided on the side wall of the movable groove 52 , and a groove and an avoidance groove 55 that cooperate with the baffle 54 are provided on the stopper 51 .

[0025] The cooperation between the baffle 54 and the side wall groove of the block 51 plays a limiting role, preventing the block 51 from disengaging from the movable groove 52 when returning to its original position, resulting in obstruction of the unlocking frame 45 to the pushing of the block 51. The shape of the groove of the block 51 and the avoidance groove 55 ensures that the rotation of the block 51 will not be hindered by the baffle 54.

[0026] Specifically, the top surface of the blocking block 42 is in the shape of an inclined surface.

[0027] The top surface shape of the blocking block 42 serves as a guide. When the user installs the connecting rod 5 to the fixed frame 41, the inclined top surface of the blocking block 42 makes it easy for the user to insert the support rod of the connecting rod 5 into the space between the blocking blocks 42, thereby facilitating the user to install the connecting rod 5 on the fixed frame 41.

[0028] Specifically, a conical protrusion is provided in the center of the filter screen 21 .

[0029] The conical protrusion of the filter screen 21 increases the contact area between the debris stored in the filter barrel 2 and the filter screen 21, which helps the filter barrel 2 to filter out the sewage from the debris. The top of the conical protrusion of the filter screen 21 is higher than the top of the filter barrel 2, ensuring the working effect of the conical protrusion.

[0030] Specifically, the position where the fixing block 22 is installed on the filter barrel 2 has a certain distance from the bottom of the filter barrel 2 .

[0031] The position of the fixing block 22 ensures that after the filter screen 21 is fixed by the fixing block 22, a certain space is left between the bottom of the filter screen 21 and the bottom of the filter barrel 2, thereby improving the efficiency of the water pipe 11 located below to discharge the filtered sewage out of the housing 1.

[0032] Specifically, two mounting rings 31 are provided at the bottom of the manhole cover 3 , and the distance between the mounting rings 31 is the same as the distance between the top groove of the shell 1 and the inner wall of the shell 1 .

[0033] By providing two mounting rings 31 , the stability of the manhole cover 3 after being installed on the mounting rings 31 is improved. The position of the mounting ring 31 located on the inner side increases the friction between the manhole cover 3 and the outer shell 1 , thereby ensuring the working effect of the mounting ring 31 .

[0034] The working principle and use process of the utility model are as follows: when sewage passes through the shell 1, the water pipe 11 located at the top delivers the sewage into the shell 1, the filter barrel 2 and the filter screen 21 filter out the debris in the sewage entering the shell 1, and the filtered sewage leaves the shell 1 through the water pipe 11 below. When cleaning the filter barrel 2, the manhole cover 3 is removed from the shell 1, and the connecting rod 5 is inserted into the fixed frame 41. As the connecting rod 5 moves, the sealing plate 43 is pushed into the storage groove 44, and the stopper 51 is pushed into the moving groove 52 by the blocking block 42. When the stopper 51 moves to the bottom of the blocking block 42, the stopper 51 returns to its original position under the action of the torsion spring shaft, and the connecting rod 5 is fixed to the fixed frame 41 through the cooperation of the blocking block 42 and the stopper 51. The connecting rod 5 is moved upward, and the filter barrel 2 passes through the blocking block 42 and the stopper 51 are carried away from the outer shell 1 by the connecting rod 5, the filter barrel 2 is placed on the ground, the fixed block 22 is moved out of the filter barrel 2, the fixation of the fixed block 22 on the filter screen 21 is released, and the filter screen 21 falls to the ground with the filtered debris, the filter barrel 2 and the filter screen 21 are separated, and the debris on the surface of the filter screen 21 is cleaned, and the filter screen 21 is installed on the filter barrel 2 through the cooperation of the fixed block 22 and the side wall groove of the filter screen 21, the filter barrel 2 is put back to its original position, the top cross bar of the connecting rod 5 is pulled out, and the unlocking frame 45 is pushed upward by the cross bar. When the unlocking frame 45 moves, the stopper 51 will be pushed into the moving groove 52, the cooperation between the stopper 51 and the blocking block 42 is released, the connecting rod 5 is pulled out of the fixed frame 41, and the sealing plate 43 returns to its original position under the action of the torsion spring shaft.
