Probability, a square bar 9 is movably connected in the square groove 2, a number of internal threaded sleeves 13 are fixed to the bottom of the manhole cover body 1, a countersunk hole is opened on the top of the square bar 9, a bolt 14 is arranged in the countersunk hole, the bottom of the bolt 14 movably passes through the manhole cover body 1 and is threadedly connected to the inner wall of the internal threaded sleeve 13, the square bar 9 is installed in the long groove 11 by the bolt 14, thereby realizing the installation and fixation of the square ring 5 and the filter cover 6, a block 10 is fixed on the side of the square bar 9 close to the square ring 5, and the side of the block 10 close to the square ring 5 is fixedly connected to the side of the square ring 5, a groove 12 is opened on the top of the manhole cover body 1 corresponding to the block 10, and the block 10 is movably connected in the groove 12.

[0030] like Figure 2 As shown, in this embodiment, an inclined guide surface 4 is provided on the side of the inner wall of the water inlet 3. The design of the guide surface 4 facilitates the insertion of the filter cover 6 into the water inlet 3 from top to bottom, thereby facilitating the installation of the filter cover 6.

[0031] like Figure 4 As shown, in this embodiment, inclined surfaces are provided on opposite sides of the connecting block 7, and the shape of the inner wall of the connecting groove 8 is adapted to the shape of the connecting block 7. After the square ring 5 is installed in the square groove 2, the side surface of the connecting block 7 fits with the inclined surface of the inner wall of the connecting groove 8.

[0036] Working principle: The filter cover 6 is installed in the water inlet 3 of the manhole cover body 1 to block garbage and foreign matter, preventing them from entering the water inlet 3 below the manhole cover body 1, thereby greatly reducing the probability of blockage of the water inlet 3. When the rainfall is heavy and timely drainage is required, use a tool to unscrew the bolt 14 from the internal threaded sleeve 13, then pinch the groove 15 to lift the square bar 9, and remove the square bar 9 from the long groove 11. At the same time, the square bar 9 drives the square ring 5 to move upward through the block 10, so that the square ring 5 drives the filter cover 6 to move upward, and the filter cover 6 is removed from the water inlet 3 of the manhole cover body 1. After removal, the water inlet 3 of the manhole cover body 1 is no longer blocked, thereby adapting to the use in heavy rainfall conditions.

[0037] After the rainwater is drained, the filter cover 6 is inserted into the water inlet 3, so that the square ring 5 fits with the inner wall of the square groove 2, and the square bar 9 fits with the long groove 11. Then the bolt 14 is passed through the square bar 9 and tightened in the internal threaded sleeve 13 to fix the square bar 9, thereby fixing the square ring 5 and the filter cover 6. After fixing, the filter cover 6 can continue to be used to block garbage and foreign matter.

[0038] At the same time, through the above-mentioned disassembly steps of the filter cover 6, when there is a lot of garbage and foreign matter in the filter cover 6, the filter cover 6 can be taken out from the manhole cover body 1, and then the garbage and foreign matter can be poured out from the manhole cover body 1, and then the filter cover 6 can be installed in the water inlet 3 of the manhole cover body 1.
