Description

A kind of Safety manhole cover

The application is that application No. is 2015109140276 applyings date are as follows: on December 12nd, 2015 denomination of invention are as follows: one The divisional application of the Safety manhole cover of kind automatic drainage

Technical field

The present invention relates to underground water transportation arts, more particularly to a kind of Safety manhole cover.

Background technique

Urban Underground pipeline is very flourishing at present, has some underground pipings to undertake conveying or the others line of underground water The laying of cable, and the exit of pipeline would generally be arranged well lid, well lid can generally be provided simultaneously with the dual of protection hole and sluicing Function, and current well lid usually or keeps normally closed or maintains a normally open generally using being manually opened and closed, in this case, It causes huge security risk or will cause impeded drainage, therefore, how to solve the problems, such as that this is field technical staff The problem of thinking deeply always.

Summary of the invention

It is an object of the invention to: overcome the above-mentioned problems in the prior art, proposes a kind of Safety manhole cover, it can According to water discharged amount number be automatically opened and closed, and the integrality of well lid will not be impacted when closed, be a kind of Very safe well lid, and have a variety of anti-pollution functions and anti-failure setting, to make well lid that non-maintaining effect may be implemented Fruit.

The purpose of the present invention is realized by following technical proposals: a kind of Safety manhole cover, comprising: upper cover and well lid sheet Body, the upper cover lid close in manhole cover body, and the upper lid surface has several water seepage holes and water hole, set at the water hole There is top cover, the top cover is set on movable plate, is equipped between the top cover and movable plate and is held out against spring, the movable plate setting On margin plate and central plate, the margin plate and central plate are fixedly connected with upper cover, between the movable plate and margin plate Horizontal direction be equipped with crossed strip, piston is equipped between the movable plate, the piston lower portion is equipped with piston rod, the piston Bar lower part is connected with water tank, and the water tank upper is equipped with several inlet openings, and opening and closing is equipped between the water tank and manhole cover body Spring, the water tank bottom are equipped with several drain holes, and the manhole cover body bottom is equipped with several discharge orifices, and such setting is normal Situation, which is lauched from water seepage hole, to be entered in water tank, and drain hole is equipped in water tank, when the influx of water tank is suitable with discharge, that is, is drained When measuring little, without opening upper cover, when Water in Water Tanks amount is excessive, compression opening and closing spring moves down piston, movable plate exists at this time It under the action of crossed strip, is drawn close to centre, drives top cover movement, open water hole, so that the discharging capacity of upper cover be made to increase Greatly, so as to cope with different sluicing demands, when water discharged amount is small, discharge reduction in water tank, piston stroking upward at this time, and piston Top is that band taper is arranged, and makes not completely disengage movable plate when piston downlink, thus can be smoothly by movable plate point in uplink It opens, to make top cover block water hole, and movable plate is fixed setting in vertical direction, so that the intensity of upper cover be made to obtain Reinforce, has the effect for bearing downward power when closed, to guarantee the safe handling of well lid.

A kind of Safety manhole cover of the invention, the water hole and top cover lean on the junction at upper cover center, pass through the top The top cover cambered surface of lid and the upper cover cambered surface of upper cover realize that cambered surface contact, such setting make two parts resistance in opposite sliding Minimum, convenient for smoothly opening and closing water hole.

Limit spring pin, institute are equipped at the faying face of a kind of Safety manhole cover of the invention, the central plate and movable plate Limit spring pins position is stated in central plate, the movable plate is equipped with limiting slot, and such setting there can be movable plate The limit of effect, and when needing to playback, its resistance will not be excessive.

The upper surface of a kind of Safety manhole cover of the invention, the water tank is water tank cambered surface, and such setting can be effective The accumulation for preventing dust, cannot be introduced into liquid when water tank causes water big can not also open water hole, prevent automatic shutter Disabler.

A kind of Safety manhole cover of the invention, the bottom surface of the water tank are that the such setting in upward convex upper convex surface can make to keep away Exempt from internal mud while blocking drain hole, flow out the water in water tank can not, thus accidentally by water when causing water little Hole is beaten greatly, and security risk is caused.

The drain hole lower section of a kind of Safety manhole cover of the invention, the convex Middle face is equipped with dredging bar, the dredging The diameter of bar is the 1/3-3/4 of sluicing bore dia, and such setting can effectively prevent drain hole and be blocked, and size is set It sets, dredging bar will not be made to result in blockage drain hole in scale removal process.

A kind of Safety manhole cover of the invention, grid is equipped at the water hole, and the maximum diagonal of the grid is less than 30mm, such setting increases the intensity of upper cover entirety, and the use function of upper lid surface can be made not set by water hole The influence set, and artificial top cover can also be carried out in some cases in this way.

A kind of Safety manhole cover of the invention, described hold out against are equipped with waterproof jacket outside spring, opening and closing spring and crossed strip, Such setting enhances the service life of each spring, and can cause elastic failure to avoid the influence of mud, to make well The disabler of lid.

A kind of Safety manhole cover of the invention is articulated connection between the upper cover and manhole cover body, and such setting makes Upper cover is integrated setting with manhole cover body, to play antitheft effect.

According to the above technical scheme, it the beneficial effects of the present invention are: overcoming the above-mentioned problems in the prior art, proposes A kind of Safety manhole cover can be automatically opened and closed according to the number of water discharged amount, and when closed will not be to the complete of well lid Whole property impacts, and is a kind of very safe well lid, and has a variety of anti-pollution functions and anti-failure setting, to make well Non-maintaining effect may be implemented in lid.
