Description

Bad smell leakage preventing structure for sewage pool access hole Technical Field The utility model relates to the technical field of sealing structures, in particular to a deodorizing outer vent door structure for a sewage pool manhole. Background Leachate, flushing wastewater and the like generated in the garbage treatment process generally enter a sewage tank for temporary storage or treatment, and the wastewater contains pollutants such as high-concentration organic matters, heavy metals, pathogenic microorganisms and the like, and if the wastewater is directly discharged, soil and water bodies can be seriously polluted, so that the sewage tank is an indispensable link in a garbage treatment system and is used for collecting, storing and primarily treating related wastewater, and environmental pollution is avoided. The sewage generated in the garbage treatment process contains high-concentration organic matters, heavy metals, pathogenic microorganisms and other pollutants, the air pollution is serious, malodor in the sewage can be diffused along with the air, so that a sewage tank is usually arranged in a sealed mode, a plurality of manhole holes and inspection and repair wells are arranged, the sealing is relatively simple and crude, the sealing is generally carried out through a well cover, odor in the sewage tank can still be emitted through gaps to influence the surrounding environment, and the problem that the odor is diffused due to poor sealing performance of the manhole holes and the inspection and repair wells is solved. Disclosure of utility model The utility model aims to provide an odor leakage preventing structure for a sewage pool manhole, which aims to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a sewage pool manhole prevents odor and leaks structure, includes the lid, the bottom of lid is provided with fixed guide rail, installs slidable carriage in the guide rail, and the one end that the carriage is close to the outside is provided with the push pedal, and the rubber strip that bonds with the lid is installed in the push pedal outside, and the inside of lid is provided with can outwards promote the carriage and make rubber strip and the sealed propulsion pressing device of drill way contact. As a still further scheme of the utility model, the pushing and pressing device comprises a fixed contact, a sliding contact, a central shaft, a pressing end and an assembly cover, wherein the assembly cover is arranged at the top of the cover body through bolts, the central shaft penetrates through the assembly cover, the pressing end is arranged at the top end of the central shaft, the fixed contact is arranged at the lower end of the central shaft, and the sliding contact capable of sliding up and down is arranged at the outer side of the central shaft. As a still further proposal of the utility model, the outer sides of the fixed contact and the sliding contact are both chamfer surfaces, one side of the sliding support close to the fixed contact is also provided with a chamfer surface, and the fixed contact can push the sliding support outwards through the chamfer surface. As a still further scheme of the utility model, a slot is arranged in the fixed contact, a limiting block which corresponds to the slot position and can be inserted into the slot is arranged at the bottom of the sliding contact, and the sliding support slides over the top of the fixed contact and then contacts with the limiting block. As a still further proposal of the utility model, a contact separation spring is arranged between the fixed contact and the sliding contact, and a limiting ring for limiting the upward movement travel distance of the sliding contact is arranged on the outer side of the center shaft. As a still further aspect of the present utility model, a return spring is provided between the pressing end and the assembly cover. As a still further proposal of the utility model, the sliding support is internally provided with a positioning groove, and the guide rail is internally provided with a plate spring penetrating through the positioning groove in the sliding support. Compared with the prior art, the utility model has the beneficial effects that: This effluent water sump manhole stink-proof gas leaks structure drives outside expansion or the inside shrink of sliding support through advancing pressing device, under the expansion state, the push pedal promotes the rubber strip and becomes closely laminating with the drill way far away, and frictional force grow simultaneously, and the installation of lid is firm, realizes sealed purpose, under the contraction state, and frictional force reduces, provides convenient when overhauling for opening the drill way.
