Background
At present, most of well lids sold in the market are not designed with a deodorizing structure, and a small part of well lids are provided with the deodorizing structure, but the deodorizing effect is similar to that of a dummy well lid, and odor emission is not substantially prevented. For example, some deodorant structures are used as deodorant boards by directly plugging holes in the anti-falling boards on the basis of the original anti-falling boards used for the anti-falling function. The odor-resistant plate has 4 claws for hanging, so that the inner space of the well lid cannot be covered completely, and odor in the well can be directly leaked out through a gap with a height difference between the claws and the well frame. In addition, there is also a special sealed well lid to aim at the problem of stink in the well, but the technical threshold and the cost of this kind of well lid are higher, are not fit for extensive popularization.

The deodorizing board assembly for the well lid comprises a deodorizing board and a top cover; the deodorizing board comprises an annular bottom wall, a first annular vertical wall, a second annular vertical wall and a flange ring; the bottom end of the first annular vertical wall is connected with the periphery of the central hole of the annular bottom wall, and a plurality of convex ribs which are distributed at intervals along the circumferential direction are arranged at the top of the first annular vertical wall; the bottom end of the second annular vertical wall is connected with the periphery of the annular bottom wall, and the top end of the second annular vertical wall is connected with the periphery of the central hole of the flange ring; the flange ring is pressed on an annular base plate which is in sealing connection with the inner peripheral surface of a well frame of the well cover, and the second annular vertical wall penetrates through a central hole of the annular base plate; the top cover is pressed on the convex ribs.
According to the embodiment of the utility model, the manhole cover comprises the deodorizing board assembly for the manhole cover.
The utility model has at least the following advantages:
1. after the deodorizing board assembly is installed on the annular base board of the well frame, the integral structure is relatively sealed, so that a good deodorizing effect can be realized;
2. When the pressure in the well is too large, the gas in the well can be slowly released through the gap between every two adjacent ribs on the deodorizing board, and when the outside rainwater or sewage flows into the well lid, the gap between every two adjacent ribs of the deodorizing board is changed into a water drain hole, so that excessive rainwater and sewage are led into the well, excessive pressure in the well frame is prevented, and the use safety is improved;
3. the deodorizing board assembly provided by the embodiment of the utility model has the advantages of simple structure and low implementation cost.

Detailed Description
The utility model will now be described in detail with reference to the drawings and specific examples.
Please refer to fig. 1 to 8. The deodorizing board assembly for the well lid comprises a deodorizing board 1 and a top cover 2.
The deodorization plate 1 is made of cast iron or carbon steel plate, and has an appearance similar to a basin. The deodorizing board 1 comprises an annular bottom wall 10, a first annular vertical wall 11, a second annular vertical wall 12 and a flange ring 13. The bottom end of the first annular vertical wall 11 is connected with the periphery of the central hole 101 of the annular bottom wall 10, and the top of the first annular vertical wall 11 is provided with a plurality of ribs 111 which are distributed at intervals along the circumferential direction. The bottom end of the second annular vertical wall 12 is connected to the periphery of the annular bottom wall 10, and the top end of the second annular vertical wall 12 is connected to the periphery of the central hole 131 of the flange ring 13. The flange ring 13 is pressed against the annular drop seat plate 3 in sealing connection with the inner circumferential surface of the well frame 4, and the second annular vertical wall 12 passes through the central hole 31 of the annular drop seat plate 3.
The annular bottom wall 10, the first annular vertical wall 11 and the second annular vertical wall 12 together define an annular recess 15. In this embodiment, the height of the first annular upstanding wall 11 is less than the height of the second annular upstanding wall 12.
In a specific embodiment, the central bore 31 of the annular drop seat plate 3 has a diameter slightly smaller than the net opening diameter of the well frame 4, and the annular drop seat plate 3 is cast integrally with the well frame 4. In other embodiments, the annular base plate 3 is a carbon steel plate additionally arranged on the well frame 4 in the later period, the outer edge of the annular base plate 3 is integrally connected with the well frame 4, and sealing measures are needed to be taken at the joint of the annular base plate 3 and the well frame 4.
Preferably, the bottom surface of the flange ring 13 is provided with a circle of limiting ring 14 extending downwards, the diameter of the limiting ring 14 is slightly smaller than that of the central hole 31 of the annular seat plate 3, and the limiting ring 14 stretches into the central hole 31 of the annular seat plate 3, so that the deodorant board 1 can be ensured not to deviate from the annular seat plate 3.
The top cover 2 is pressed against the aforementioned plurality of ribs 111. Preferably, the periphery of the top cover 2 is provided with a circle of turnups 21 bent downwards, and the turnups 21 encircle the periphery of the plurality of ribs 111.
After the deodorant board assembly of this embodiment is installed on the annular seat board 3 of the well frame 4, the overall structure is sealed relatively, so that the deodorant effect can be played. When the pressure in the well is too high, unsafe factors can be generated, and the reserved holes and gaps (mainly the gaps g between every two adjacent ribs 111) on the deodorizing board can timely adjust the internal and external pressures. Specifically, after the deodorization plate assembly is installed, a small amount of liquid is poured into the groove in the middle of the deodorization plate 1 by collecting rainwater and sewage or artificially. When the pressure in the well is too high, the gas in the well is slowly released through the gap g between every two adjacent ribs 111 (the gap is used as an overflow hole), and meanwhile, the outside liquid is used as a blocking medium, so that the gas in the well is released more slowly. When rainwater or sewage flows into the well cover from the outside, the gap g between every two adjacent ribs 111 of the deodorizing board (which is used as an overflow port at the moment) is changed into a water drain hole, so that excessive rainwater and sewage are led into the well to prevent excessive pressure in the well frame.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
