Description
Technical field
The present invention relates to the city pavement manhole cover of the antitheft water drainage of a kind of multifunctional safe, belong to municipal engineering technical field.
Background technology
City pavement manhole cover relates to the well lid of the industries such as underground water supply and drainage pipeline, postal, electricity, letter shoot road, and developing history is long.Traditional city pavement manhole cover, only lays a simple removable cover in the fixed sheath normally on well mouth, or opens cover plate at one end ready-made hinge of well lid, or fixes with simple netted rope below well lid in order to safety.Due to the defect that traditional well lid exists, the disaster that a lot of casualties that China causes because of well lid safety problem every year and car accident and countless well lid stolen perhaps many cities ponding or underground water cause after rising suddenly and sharply and washing away well lid shows, replaces traditional well lid in the urgent need to the new pattern manhole cover researching and developing the real safe antitheft of a kind of energy.Tradition well lid weak point is:
1. the mid-movable well lid put of traditional well lid is often crushed by heavy-duty vehicle, or is stolen by people, or is washed away by flood, causes well head vacancy to cause vehicle and pedestrian by causing traffic jam, more seriously to cause pedestrian to fall the accident of dying;
2. though occurred that one is fixed antitheft in well lid one end by hinge through improving in traditional well lid, or nylon rope is installed as protective screening in well lid one end, but due to heavy-duty vehicle extrude for a long time cause well lid be out of shape after also well lid can be washed open because water level rising pressure in underground water pipeline is excessive, Long-Time Service nylon rope net performs practically no function after rotting with age, accident that the well lid washed open and rotten protective screening can cause vehicle equally and pedestrian is impassable and pedestrian's pendant is died;
3. in traditional well lid, also there is the way only being held the aperture insertion key installation safety lock that key is come in and gone out on individual layer well lid by, but owing to being out of shape after the heavy-duty vehicle extruding well lid of road traveling, cannot open after cannot locking or lock after causing well lid to misplace, affect sewer pipe to safeguard, well lid can be caused to scrap or pattern manhole cover lock disabler if pry open well lid by force, have a strong impact on operating efficiency simultaneously;
4., after conventional well covers, the surface gathered water because of torrential rain formation cannot be got rid of can cause urban pavement flood, affects vehicles and pedestrians;
5., after conventional well covers, if meet extra torrential rain when making water level in underground pipeline go up to form outside extruding force, if well lid is not opened flood discharge, well lid will be washed open or wash away; If well lid is opened but can cause vehicle and pedestrian impassable, even also can cause pedestrian's personal safety accident.
Summary of the invention
For solving safe antitheft that existing urban road underground pipeline exists, water drainage, flood discharge, pendant people fall the difficult problems such as thing, the invention provides the city pavement manhole cover of the antitheft water drainage of a kind of multipurpose safety, many in order to reach purposes, both safe antitheft, have again and alleviate water drainage, flood discharge decompression and anti-falling stop people fall the object of formal matter event.
For solving its technical problem, the city pavement manhole cover of the antitheft water drainage of the multipurpose safety that the present invention designs, comprising: base, sheath, protective screening, dual pattern manhole cover lock, overturn cover and swivelling cover, and its feature is:
1. on base, be provided with sheath, the inwall of sheath is provided with two-layer step, and lower floor's step is placed with and is inserted into formula protective screening, upper strata step is provided with porous overturn cover, is provided with porous swivelling cover on the surface of overturn cover;
2. sheath described in is circular ring type cast iron quality boss, and form one by the surface of multiple reinforcing rib and base, the running-on of this sheath is provided with the hinge be made up of overturn cover bearing and overturn cover rotating shaft, overturn cover is connected with sheath by this hinge;
3. overturn cover described in is circular irony foundry goods plate, in overturn cover, center surrounding is provided with the limbers of multiple flowing water, centre bottom is connected as a single entity for column type blank pipe that the is interspersed and rotating shaft of supporting swivelling cover by one, the reinforcing rib that many symmetrical is had at the back side of overturn cover, adjacent two reinforcing ribs are provided with a swivelling cover spacer pin and another swivelling cover spacer pin, and these two angles between spacer pin and center are 45 degree; The hole wall of a flowing water limbers is fixed with pattern manhole cover lock, is provided with multiple elastic damping block or shock absorption bar on overturn cover surface;
4. swivelling cover described in is circular ironcasting, the limbers of multiple non-slipping block and multiple flowing water is provided with on the surface of this swivelling cover, circumferentially with on the excircle of swivelling cover the reinforcing rib that can strengthen supporting power is equipped with in each limbers, a swivelling cover rotating shaft of protruding is provided with downwards at the center on the surface of this swivelling cover, during installation, swivelling cover rotating shaft interts in the column type blank pipe at overturn cover center, and is fixed with swivelling cover gag lever post and the spacing flange of swivelling cover by screw and nut on the base plate of swivelling cover rotating shaft;
5. between any two symmetrical flowing water limberss of swivelling cover surrounding on the surface, be furnished with one special open fulcrum and swivelling cover by swivelling cover handle, swivelling cover and open the swivel mount that spacing kelly forms, for swivelling cover is rotated there being the overturn cover upper edge of damping block or shock absorption bar, flowing water limbers on two cover plates is overlapped or closes, become common closed state or drain off floodwaters flood discharge time open mode;
6. pattern manhole cover lock described in is by locking supporting seat, the spacing end cap of lock tube, well lid locking plate, lock core, lock tube, locking plate rotating shaft, locking plate clamp nut, lock body that locking plate limited screw forms and the key that is made up of key overcoat, keyhole, key handle forms.During use, key overcoat, keyhole, fit through key handle with the lock core of pattern manhole cover lock, lock tube well lid locking plate is stirred, make it and the pattern manhole cover lock bayonet lock phase hook on jacket inner wall or unhook, to reach the object of locking or unblanking.
The present invention, compared with traditional well lid, has following feature and advantage:
1. be inserted into formula protective screening because being provided with bottom lid of the present invention, and this net being the material not easily getting rusty and rot makes, can effectively preventing object or person person from falling into well head, major traffic accidents or personnel casualty accidents can be avoided;
2. because the present invention is provided with Double-layer drain cover plate, two cover plates are all fixed on the base with sheath, and are equipped with reinforcing rib and elastic damping block or shock absorption bar in two-layer well lid, therefore have good crushing resistance, effectively can prevent overweight lorry to crush well lid, have good soundness;
3., because of between two-layer well lid, be provided with two kinds of different locksets, only have after opening two locksets respectively, just can open well lid, well lid can not only be opened because of need of work, under enter underground pipeline maintenance or watch, can effectively prevent from again stealing;
4. because two-layer well lid is equipped with multiple limbers, urban pavement ponding can pass through this many limbers, flows into sewer, allows ponding discharge from sewer, is conducive to alleviating urban pavement flood.Meanwhile, can also go up at sewer water level, hydraulic pressure excessive time by outlet pass flood discharge corresponding to two-layer well lid, cause the accident after well lid of avoiding destroying by rush of water.
