Abstract

The utility model discloses a manhole cover capable of automatically lifting and descending, which comprises a cover body and a framework which has the same size as that of the cover body and is embedded into the ground, wherein a connecting rod which can move up and down penetrates through the center of the framework, the top end of the connecting rod is connected with the cover body, and the bottom end of the connecting rod is fixed with a float ball. When flood is discharged, the cover body is lifted via the float ball and the connecting rod by relaying on the buoyancy of water, after the water subsides, the cover body returns to the original position under the action of gravity, so the automatic flood discharge purpose is realized.

Description

But a kind of manhole cover of automatic lifting

Technical field

The utility model relates to a kind of manhole cover, but a kind of manhole cover of automatic lifting particularly.

Background technology

In the drainage system in modern city, manhole cover is as an important utensil, and its main purpose is for to cover in husky well, in case pedestrian or other object are fallen into Sha Jingzhong.But along with the very fast development of urban construction, the load of the drainage system in city also increases day by day, and especially in summer during heavy rain, the untimely ponding on a large scale that causes easily of rain drainage need be opened manhole cover in this case usually and come flood discharge.But manhole cover commonly used need manually be moved and in the flood discharge back manual restoration that finishes, have thousands of manhole covers in the city, and manually moving one by one and restore is a huge engineering, finishes between flush period more difficult.In addition, current husky well to flood discharge phase uncovered lacks enough cautions, easily pedestrian or vehicle is caused unexpected injury, especially under the situation that husky well is covered by ponding.

Summary of the invention

Overcome the deficiencies in the prior art in order to solve, the utility model provides a kind of can rise flood discharge automatically, and the novel manhole cover of enough cautions is provided.

The technical solution adopted in the utility model is:

But a kind of manhole cover of automatic lifting comprises lid and skeleton identical with the lid size and that setting-in is gone into ground, and described frame center is coated with the up and down connecting rod of energy, and the top and the lid of described connecting rod fix, and the bottom also is fixed with ball float.

As further improvement of the utility model, not only drain hole can be set on lid, in the manhole cover both sides auxiliary discharge opening can also be set.

As further improvement of the utility model, skeleton is a cell structure, and is provided with lid rise sensor circuit thereon, and links to each other with Traffic alarm light, be provided with indication and flashing circuit in the Traffic alarm light, Traffic alarm light glimmers and throws a circular radium-shine hot spot on lid when lid rises.

The beneficial effects of the utility model are: the skeleton setting-in of this manhole cover is gone into ground, under normal condition, because of action of gravity lid closure, drains the drain hole that a small amount of rainwater can be from lid or the auxiliary discharge opening of manhole cover both sides.Under the flood discharge state, when the water surface of sewer rises to when flooding ball float, because the buoyancy ball float rises with the water surface, and by connecting rod jack-up lid, rainwater can flow into husky well from the gap between lid and the ground, to reach the purpose of flood discharge.At this moment, the warning lamp that the roadside is provided with receives the signal that lid is opened, and the warning lamp flicker is also throwed a circular radium-shine hot spot and point out pedestrian or vehicle on lid, avoids contingency to take place.In addition, because lid just rises to certain altitude in this manhole cover device, still cover husky aboveground side in vertical direction, and at the aboveground skeleton that also is coated with lattice structure of sand, this has just further been avoided the pedestrian to fall into the generation of Sha Jing and so on contingency.After flood discharge is finished, because the sewer water surface descends, restore automatically at the action of gravity lower cover, like this, this manhole cover has just reached the purpose of design of its automatic flood discharge.In addition, owing to adopt the skeleton of lattice structure in this manhole cover device,, adopted fixedly connected between each parts when the heavy vehicle process can and prevent to damage manhole cover with the even dispersion of pressure, its skeleton also setting-in is gone into ground, has prevented that effectively some people from spiriting away.

Structural representation when Fig. 2 is the unassembled lid of the utility model.

The specific embodiment

See figures.1.and.2, but a kind of manhole cover of automatic lifting comprises lid 1 and skeleton 2 identical with lid 1 size and that setting-in is gone into ground, its center be coated with can be up and down connecting rod 3, the top of described connecting rod 3 links to each other with lid 1, the bottom is fixed with ball float 4.Under normal condition, because of action of gravity lid 1 closure, under the flood discharge state, when the water surface of sewer rises to when flooding ball float 4, because buoyancy ball float 4 rises with the water surface, and by connecting rod 3 jack-up lids 1, rainwater can flow into husky well from the grid of the gap between lid 1 and the ground on skeleton 2, to reach the purpose of flood discharge.In addition, still keep in vertical direction after lid 1 rises covering husky aboveground side, and at the aboveground skeleton that also is coated with lattice structure of sand, this has just reduced the possibility that accident that the pedestrian falls into Sha Jing takes place effectively.Skeleton 2 adopts cell structure can promote the anti-pressure ability of manhole cover effectively, prevents to damage because of the spreading of heavy vehicle.

In addition, skeleton 2 and ground, connecting rod 3 and ball float 4 all can adopt special antitheft mode to fix between connecting rod 3 and the lid 1, connect a parts such as using the anti-theft screw that needs specific instrument to dismantle to fix, and prevent that manhole cover is stolen.

Also be provided with drain hole 11 on lid 1, under non-flood discharge state, a small amount of rainwater can flow into husky well by the drain hole on the lid 11, can add auxiliary discharge opening 12 in the manhole cover both sides in the bigger area of amount of precipitation, to drain more rainwater.

The cross section of this manhole cover connecting rod 3 is a cross, and this can not only increase the structural strength of connecting rod 3 effectively, and the waving of the horizontal direction that causes because of current or air-flow can effectively reduce lid 1 and rise the time.

For increasing the safety of pedestrian and vehicle, this manhole cover also is connected with Traffic alarm light, skeleton 2 is provided with lid 1 and rises sensor circuit, and with Traffic alarm light in the indication that is provided with link to each other with flashing circuit, Traffic alarm light glimmers and throws a radium-shine circular light spot on lid 1 when lid 1 rises, with caution pedestrian and vehicle.
