Embodiment

[0021] Embodiment: a kind of anti-odor and anti-blocking manhole cover, as Figure 1 to Figure 5 As shown, it is installed on the well cover mounting seat 1, including a circular well cover body 2, and the position near the edge of the well cover body 2 is evenly provided with a number of first drainage holes 3 in the vertical direction, through which the first drainage holes 3 can be easily Drain well. Yet the peculiar smell of sewer also is volatilized from the first drainage hole 3 under the higher condition of temperature.

[0022] The well cover body 2 is provided with a cavity 4 filled with air 5 . The cavity 4 is uniformly provided with fins 30 for increasing the heat exchange area. The fins 30 can increase the heat exchange area between the air 5 and the manhole cover, thereby increasing the heat exchange efficiency, so that the air 5 in the cavity 4 can be quickly It changes with the change of external temperature, which is beneficial to produce better deodorizing e...

Abstract

The invention discloses a deodorant and anti-blocking well cover. According to the technical scheme of the deodorant and anti-blocking well cover, the higher the temperature is, the more serious the odor in a sewer is, therefore, due to thermal expansion and cold contraction, when at high temperature, air expansion pushes a first piston to move and further to block drainage holes through a sealing retainer to achieve deodorant effects; meanwhile, when drainage is required, the temperature of the well cover can be reduced, air contraction inside a cavity enables the drainage holes to restore to a through state to avoid influence on drainage; also, for avoiding blocking of the drainage holes, when a vehicle passes by, a driving mechanism can store high-pressure gas inside a gas storage tank, so that when a first drainage hole is blocked, the gas storage tank can be opened through a switch mechanism to blow off impurities inside the first drainage hole through a gas outlet hole to achieve the anti-blocking effects. The deodorant and anti-blocking well cover achieves good deodorant effects and good drainage functionality and can avoid blocking of the drainage holes.

Description

technical field [0001] The invention relates to the field of municipal engineering equipment, in particular to an anti-odor and anti-blocking manhole cover. Background technique [0002] When people walk in the city, they often ask about peculiar smells. These peculiar smells not only affect the appearance of the city, pollute the air, and are harmful to the human body, but also affect the mood of the walkers. By exploring the source of these odors, we can know that these odors come from the sewer, overflowing through the drain on the manhole cover. So we need to explore a way to stop the overflow of the smell. [0003] For example, a kind of anti-odor manhole cover mentioned in the Chinese patent whose notification number is CN202450618U adopts the technical scheme as follows: it includes a cover body, and the cover body is provided with circularly distributed water filtering holes, and the lower edge of the cover body faces inwardly. The curl hook is formed with an arc-s...
