[0023] like Figures 3 to 6As shown, in another embodiment of the present invention, a sealing block 6 is installed on the lower side of the manhole cover 2 at one end of the interior of the placement groove 3, a sealing groove 7 is provided on the inner lower surface of the placement groove 3, and the lower end of the sealing block 6 is snap-fitted and installed in the interior of the sealing groove 7, a connecting groove 503 is provided on the lower surface of the manhole cover 2, and the upper end of the filter barrel 501 is snap-fitted and installed in the interior of the connecting groove 503, a plurality of limiting blocks 504 are installed on the outer upper end of the filter barrel 501, a plurality of limiting grooves 505 are provided inside the connecting groove 503, and the limiting blocks 504 are snap-fitted and installed in the interior of the limiting grooves 505 respectively, a movable groove 506 is provided at the inner lower end of the manhole cover 2, and a movable ring 507 is movably installed in the movable groove 506, and a plurality of grooves 508 are provided inside the movable groove 506 and on one side close to the limiting groove 505. An extension frame 509 is installed on one side near the groove 508, and the extension frame 509 is movably installed inside the groove 508. A positioning groove 512 is provided between the limit block 504 and the groove 508. A positioning frame 511 is installed on one side of the extension frame 509 close to the positioning groove 512. The positioning frame 511 is respectively engaged and installed inside the positioning groove 512. A spring 510 is installed between the side of the extension frame 509 away from the positioning frame 511 and the groove 508. A guide groove 514 is provided at the lower end of the interior of one of the grooves 508, and a connecting plate 513 is movably installed inside the guide groove 514. The upper end of the connecting plate 513 is connected to the extension frame 509, and a handle 515 is installed at the lower end of the connecting plate 513. The handle 515 is movably located on one side of the filter barrel 501.

[0024] When the filter barrel 501 needs to be installed, the user first drives the connecting plate 513 to move along the guide groove 514 through the handle 515, and the connecting plate 513 drives the extension frame 509 and the movable ring 507 to rotate, so that the extension frame 509 drives the positioning frame 511 to disengage from the interior of the limit groove 505, and at the same time, the extension frame 509 squeezes the spring 510. Then the user can take the filter barrel 501 and let the filter barrel 501 drive the limiting block 504 along the limiting groove 505 to insert into the interior of the connecting groove 503 to achieve the installation of the filter barrel 501.

[0025] When the filter barrel 501 needs to be disassembled, it is only necessary to use the handle 515 to move the connecting plate 513 along the guide groove 514, and let the connecting plate 513 drive the extension frame 509 and the movable ring 507 to rotate, so that the extension frame 509 drives the positioning frame 511 to disengage from the inside of the positioning groove 512, and then the filter barrel 501 can be removed to clean the impurities inside it.

[0026] The working principle of this municipal road drainage filter device:

[0027] When in use, first when it is necessary to install the filter barrel 501, the user first uses the handle 515 to drive the connecting plate 513 to move along the guide groove 514, and allows the connecting plate 513 to drive the extension frame 509 and the movable ring 507 to rotate, so that the extension frame 509 drives the positioning frame 511 to disengage from the interior of the limit groove 505, and also allows the extension frame 509 to squeeze the spring 510. Then the user can take the filter barrel 501 and let the filter barrel 501 drive the limiting block 504 along the limiting groove 505 to insert into the interior of the connecting groove 503 to achieve the installation of the filter barrel 501. Then, after the installation of the filter barrel 501 is completed, the user can release the handle 515, and then the spring 510 can push the extension frame 509 to reset, allowing the extension frame 509 to push the positioning frame 511 to insert into the relative positions. The inside of the positioning groove 512 is engaged to realize the installation of the filter barrel 501. Then, after the installation of the filter barrel 501 is completed, the user can install the manhole cover 2, let the manhole cover 2 be stuck into the inside of the placement groove 3, and the filter barrel 501 enters the inside of the vertical shaft 4. Finally, the engagement between the sealing block 6 and the sealing groove 7 is realized to achieve the seal between the manhole cover 2 and the placement groove 3, so that rainwater can only be drained along the through holes on the manhole cover 2, which is more convenient for the filter barrel 501 to filter and separate rainwater and impurities, allowing rainwater to enter the interior of the vertical shaft 4 through the filter screen and the drainage groove 502 for discharge, while impurities are retained in the filter barrel 501 for storage, avoiding impurities from clogging the interior of the vertical shaft 4. At the same time, it is also convenient for the later user to clean the impurities inside the filter barrel 501, which is more simple.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention.
