Abstract
The present invention is an automatic cover for gully and aims at preventing sewer gas pollution of air, preventing mosquito and other insect flying out from the sewer and avoiding other inconvenience caused by opened gully. The automatic cover with weight balance may be opened by water flow and closed automatically in the time of no water flow. The present invention can improve environment obviously.
Description
Technical field
This automatic opening and closing door is that a kind of preventing returned on the effluent sewerage foul smell, and small article falls into the automatic opening and closing door that can take out again behind the sewer.
Technical background
Existing sewer mouths such as the whole nation, each province and city, streets and lanes, living area, owing to can not close, every minute sewage effluent foul smell, not only cause air pollution, also the serious harm people's is healthy, mosquito flies out and the people is bitten very difficult taking-up the after small articles such as key, coin fall in the sewer simultaneously.
Summary of the invention
This automatic opening and closing door is at the sewer place, and iron safe side off the net install, and makes and well head framework of the same size according to the well head shape, movable pedestal is equipped with on the following symmetrical both sides of framework, be used for fixing the door leaf that has the counterweight sign indicating number, rubber weather strip all is equipped with on base of frame four limits, keeps tight-closed.When water flowed into well head, automatic door was opened automatically by water slug, and current stop the back automatic door and close voluntarily.
When this automatic opening and closing door impacts at no current, because the pressure of door leaf counterweight sign indicating number, remain sealing state, therefore stoped effectively in the sewer that foul smell back well head is of living in to have caused air pollution, fly out with mosquito in the sewer human body is bitten, and can be easily the small article that falls in the sewer be taken out, for society created good air ambient and DEVELOPMENT PROSPECT huge.
Description of drawings
Below in conjunction with accompanying drawing this automatic opening and closing door is further described.
Fig. 1 is an automatic opening and closing door closing structure schematic diagram.
Fig. 2 is an automatic opening and closing door opening structure schematic diagram.
The specific embodiment
As shown in Figure 1, the 1st, automatic opening and closing door frame fixation hole, the 2nd, automatic door framework, the 3rd, surrounding, framework base weather strip, the 4th, the movable pedestal of door leaf, the 5th, door leaf counterweight sign indicating number, the 6th, automatic door leaf, the 7th, door leaf symmetry weather strip.
Whole automatic door switch door manufacturing process is simple, and fitting operation is convenient.
Claims (1)
- Automatic opening and closing door is characterized in that there is fixing hole (1) the symmetrical both sides of automatic switch door frame (2), base of frame symmetry both sides are equipped with movable pedestal (4) and are had the door leaf (6) of counterweight sign indicating number (5), under no current impact, because the due to pressure of counterweight sign indicating number, automatic door remains closed condition, simultaneously (3) and door leaf are closed corresponding position (7) weather strip all are housed around automatic door framework base, have controlled the interior foul smell of sewer effectively and have leaked.Further describe:(1) fixing hole (2) framework (3) and (7) weather strip(4) movable pedestal (5) counterweight sign indicating number (6) door leaf
