Description

Deodorization noiseproof casting iron well lid

Technical field

The utility model relates to the well lid of municipal water down or inspection shaft, particularly includes the casting iron well lid of deodorization and noiseproof function.

Background technology

In supply and drain water system, usually relate to and use the sewer manhole lid device,, all will use manhole lid device as setting up the place of well body at manhole, valve well, sewage well or other.Manhole lid device commonly used is made up of casting iron well lid seat and well lid etc.; casting iron well lid on road especially; in use; can looseningly produce the gap between manhole cover base and the well lid; at this moment vehicle one is through sending noise; usually can be subjected to vehicle through out-of-date manhole cover base that sends and the invasion of well lid impact sound at highway and the other resident who lives of sub-district road; in addition; unpleasant foul smell in living area septic tank or the effusion of other manholes; also contaminated environment; to requiring the zone of environment strictness, just there is the requirement inspection shaft to use the Odour resistant well cover device.In a period of time in past, some new technology have appearred in the manhole lid device, as mainly comprising the framework that is fixed in the inspection shaft place in this invention of Chinese patent (200410015833.1) " magnetization deodorization inspection shaft lid ", be fixedly connected with at least one pair of magnetization locating piece on the bottom surface of framework, the magnetization locating piece has the shoulder hole that is made of screwed hole and through hole.The two sides of anti-foul door respectively have first blind hole, one end of the outer valve jacket of magnetic tube is sleeved in first blind hole, the other end is sleeved in the through hole, and the magnetization locating piece on anti-foul door and its both sides is linked together, and is set with on the external diameter of valve jacket to be used for spacing magnetic core turn outside magnetic tube.Have second blind hole in the outer valve jacket of magnetic tube, the diapire of its second blind hole is provided with conical groove; The magnetic core dog screw passes the screwed hole and second blind hole, and its end and conical groove are inconsistent.It is introduced that the useful effect of this invention is: when on the ground ponding being arranged, anti-foul door can be opened automatically, wait ponding to discharge after, anti-foul door can be closed automatically, ground water can be discharged from inspection shaft like this and can prevent that again the foul smell in the inspection shaft from emitting.Also have (98235449.5) " a kind of manhole cover deodorization apparatus " in addition, this device, comprise the matrix that has the grill-shaped outfall, in two edges, outfall bottom surface, be respectively arranged with that relatively to extend and manufacture the cross section that forms with its terminal contacted mode employing elastomeric material closed together to the outfall side-lower be the baffle plate of v-shaped structure, and the closure plate that is arranged on its both ends.Adopt said structure, rely on the water own wt that the v-shaped structure baffle plate is opened with to cloudy well internal drainage when having reached draining, can rely on the elasticity of v-shaped structure baffle plate self that the grill-shaped outfall is closed during anhydrous row again, filthy gas escapes the purpose that reaches the breeding of inhibition mosquitos and flies simultaneously again in the cloudy well to stop.The apparatus structure of the technology of these patents is corresponding comparatively complicated, and cost is higher, in the municipal engineering practice, further investigation reveals that enforcement is less.

The purpose of this utility model is in order to overcome the unpleasant odor pollution environment in living area septic tank or the effusion of other manholes, also overcome some Odour resistant well cover complex structures, shortcoming that manufacturing cost is high in addition, preparation provides a kind of simple in structure, durable, deodorization, casting iron well lid device that noise-proof performance is good, has reached this purpose through inventor's effort.

Summary of the invention

In order to realize this purpose, a kind of sewer deodorization noiseproof casting iron well lid of inventor's design, it is by well lid 1, manhole cover base 2, the groove 3 of dress noiseproof rubber strip, noiseproof rubber strip 4, what noiseproof rubber strip and manhole cover base can be linked together is connected screw 5, deodorization inner cap 6, water sealed tank 7 is formed, the groove 3 of the dress noiseproof rubber strip of processing has 6～8 on manhole cover base 2, its total length is about half of girth, in each groove 3, be drilled with through hole 5, there is 1～3, can noiseproof rubber strip 4 be securely fixed in the groove 3 with screw during installation, the noiseproof rubber strip of adorning 4 require to exceed groove 3 and have about 1.5 centimetres, also processed water sealed tank 7 on the manhole cover base 2, after manhole cover base 2 installs, water filling in water sealed tank 7, cover deodorization inner cap 6, the noiseproof well lid 1 of deodorization is covered just becomes deodorization noiseproof casting iron well lid duty again.

This deodorization noiseproof casting iron well lid that the utility model provides; between the contact surface of well lid and manhole cover base, accompany elastic cord breaker; noise when it can effectively prevent the well lid use; water in the deodorization water sealed tank is replenished by natural precipitation; the deodorization its anti-noise structure is succinct; reliably; fabrication and installation technology is uncomplicated; save material again; therefore; it prevents that for road construction and maintenance and reduction city noise thereof air pollution is very effective, increases the environmental protection function; have fabulous realistic meaning to improving the improvement of town dweller's quality of life, can in urban operating mechanism, widely popularize.
