Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5 As shown, this utility model provides an odor-proof municipal sewer manhole cover, including a manhole cover body 1, a water inlet hole 11 on the manhole cover body 1, an odor-proof component 3 connected to the lower surface of the manhole cover body 1, and a filter component 2 installed in the water inlet hole 11.

[0020] The odor-proof component 3 includes a circular block 31 and a waterproof activated carbon adsorption block 39. The circular block 31 is welded to the lower surface of the manhole cover body 1. A positioning groove 32 is formed on the lower surface of the circular block 31, and a positioning block 33 is movably inserted into the positioning groove 32. Through holes 34 are formed on the outer surfaces of both the positioning block 33 and the circular block 31. Bolts 35 are movably inserted into the through holes 34, and nuts 36 are threaded onto the outer surface of the bolts 35. A fixing cylinder 37 is fixedly installed on the lower surface of the positioning block 33, and a fixing cover 38 is installed on the lower surface of the fixing cylinder 37. The waterproof activated carbon adsorption block 39 is movably fitted to the inner surface of the fixing cylinder 37. Ventilation holes 4 are provided on the outer surfaces of both the 37 and the fixed cover 38. By welding the round block 31 to the manhole cover body 1, the positioning block 33 on the fixed cylinder 37 can be inserted into the positioning groove 32. By inserting the bolt 35 into the through hole 34 opened on the round block 31 and the positioning block 33, and connecting with the nut 36, the odor can be adsorbed by the waterproof activated carbon adsorption block 39 placed in the fixed cylinder 37 during the use of the manhole cover body 1, achieving the effect of odor prevention. After the waterproof activated carbon adsorption block 39 has been used for a period of time, the fixed cover 38 can be removed by rotating the mounting bolt 381 to replace the waterproof activated carbon adsorption block 39.

[0021] The lower surface of the fixed cover 38 is threaded with a mounting bolt 381, the end of which is threaded into the inside of the fixed cylinder 37. The fixed cover 38 can be removed from the fixed cylinder 37 by means of the mounting bolt 381. The upper surface of the fixed cover 38 is fixed with a square block 382. The lower surface of the fixed cylinder 37 is provided with a square hole 383. The square block 382 is movably inserted into the square hole 383 to facilitate precise positioning when the fixed cover 38 is installed on the fixed cylinder 37.

During the use of the manhole cover body 1, the waterproof activated carbon adsorption block 39 placed in the fixing cylinder 37 can adsorb the odor to achieve the odor prevention effect. After the waterproof activated carbon adsorption block 39 has been used for a period of time, the fixing cover 38 can be removed by rotating the mounting bolt 381 to replace the waterproof activated carbon adsorption block 39.

[0025] By inserting the fixing frame 21 into the water inlet hole 11, the friction can be increased by the rubber friction block 22. Water can filter out impurities by passing through the filter screen plate 23. When it is necessary to clean the impurities on the filter screen plate 23, the support rod 24 can be lifted through the pull port 26 to clean the impurities on the filter screen plate 23.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
