Abstract

The utility model relates to an inspection well cover with legs. The inspection well cover with the legs comprises an inspection well cover body (1). The inspection well cover with the legs is characterized in that the legs (2) of the inspection well cover are arranged at the peripheral positions of the inspection well body (1) and on the face facing towards an inspection well in a connecting mode, and materials of the legs of the inspection well cover are hard materials. The length of each leg (2) of the inspection well cover is within the range value between 20 centimeters and 2 meters. The inspection well cover with the legs cannot flow around the inspection well and can only be ejected open right above the inspection well under the condition that the inspection well cover is ejected open by a flood, wherein pressure, inside a sewer line, of the flood increases. Under the condition that the flood weakens and subsides, the inspection well cover with the legs can fall back to the position of an inspection well opening from right above the inspection well and covers the inspection well again under the effect of gravity and the guidance of the legs of the inspection well cover, and therefore personnel loss and vehicle loss when pedestrians and vehicles pass through the inspection well with the inspection well cover being washed away by the flood can be avoided.

Description

The inspection well cover that leg is arranged

Technical field:

The utility model relates to a kind of inspection well cover.

Background technology:

At present the rise situation of flood of each metropolis road of the whole nation happens occasionally.The flood of Beijing on the 21st is exactly example as in July, 2012: under field conditions (factors), heavy rain drops on ground and progressively converges need a process in the river.But all hardened in ground now, lost water seepage function, and rainwater is more flows to rapidly the river course by drainage system quickly.The river course can't hold so many water at short notice, overflows so flood appears in several places.Beijing Wide Channel Gate ponding reaches 4 meters deeply, is exactly because Pekinese's south city moat water level is too high, has occurred pouring in down a chimney.

Pour in down a chimney the flood in the city of going down town, the pressure of the water in sewer pipe is increased.The pressure of the water of the sewer pipe in low-lying location, city also can be very large simultaneously.The situation generation of inspection well cover is knocked over, washed to the flood that so often can see the pressure increase of urban sewage pipeline.Because after old-fashioned inspection well cover is backed down by flood, do not have other thing to be fixed in the position of original inspection shaft, drifting about and go to other place in the position that makes inspection well cover break away from inspection shaft, is difficult to automatic cover and returns inspection shaft.Thereby must dependence manually go an inspection well cover again to build.When flood, inspection well cover is washed from the position of inspection shaft, in the time of surface gathered water, the pedestrian is not easy to find that inspection well cover is rushed to open, if at this moment the pedestrian is arranged, the inspection shaft of vehicle through not having inspection well cover to cover easily causes casualty accident.

We also often can see in the urban flood defence process, are backed down the situation of pressurization sand hill on inspection well cover by the flood of inspection shaft inside in order to prevent inspection well cover.But the Manual pressurizing sand hill is time-consuming, effort.

The utility model content:

The utility model is will solve old-fashioned inspection well cover easily to be knocked over, wash from by the flood that the inspection shaft internal pressure increases.So that cause the inspection shaft that does not have inspection well cover to cover, at pedestrian and vehicle through the out-of-date problem that damages.

For addressing the above problem, the utility model provides a kind of inspection well cover that leg is arranged, and it comprises inspection well cover body 1, it is characterized in that: the position of inspection well cover body 1 periphery in the one side towards inspection shaft, is connected with the leg 2 of inspection well cover.The length of the leg 2 of inspection well cover is in the value range of 20 centimetres to 2 meters.

The periphery of common inspection well cover is connected with leg by the direction of inspection shaft inside.Leg is connected firmly with being connected to of inspection well cover is fixing, and the Design of length of leg is between the length of 20 centimetres to 2 meters.The leg of inspection well cover is to be inserted in inspection shaft, leans against on the inwall of inspection shaft surrounding, can be up and down in inspection shaft, but can not move to surrounding.When the inspection well cover that leg is arranged is backed down by the inner flood of sewer pipe, because the leg of inspection well cover is long, and also hard, the barrier force effect that the leg of inspection well cover and inspection shaft surrounding wall form, inspection well cover can not drift about to surrounding so, also can not knocked over.But can move up and down, after the peak value of flood, impulse force weakens, disappears, and inspection well cover and under the guiding function of the leg of inspection well cover, can fall directly over inspection shaft under the effect of self gravitation, just covers on inspection shaft.

Thinking of the present utility model is: with the leg of inspection well cover and the barrier force of the interior surrounding wall formation of inspection shaft, when the flood that inspection well cover is increased by the inspection shaft internal pressure backs down, do not drift about to the inspection shaft surrounding.Under the guiding of inspection well cover leg, inspection well cover only can rise upwards, treat that flood weakens, and inspection well cover falls downwards automatically, and inspection shaft is covered.

The beneficial effects of the utility model are: have the inspection well cover of leg simple in structure, cost of manufacture is low, and the inspection well cover that the flood that increased by the sewer pipe internal pressure backs down can not be drifted about to surrounding, also can not knocked over, and only can rise to the inspection shaft top.After weakening, decorporate, flood can automatically cover on inspection shaft.Can avoid pedestrian, vehicle to fall into the inspection shaft that covers without inspection well cover.

Description of drawings:

Fig. 1 is the structural representation that the inspection well cover of leg is arranged, and the inspection well cover of this figure is circular.Wherein: the leg 2 of inspection well cover body 1, inspection well cover.Leg 2 designs of inspection well cover are fixed on one of them face of inspection well cover body 1, there is one of leg to face the direction of inspection shaft, the leg 2 of inspection well cover equidistantly distributes on inspection well cover, the length of each of inspection well cover leg is all the same with weight, because the weight of inspection well cover all directions is all the same, at this moment when flood backed down inspection well cover, inspection well cover can rise directly over inspection shaft, was not easy.

Fig. 2 is the schematic diagram that the inspection well cover of leg is arranged, and this figure inspection well cover is square.Wherein: the leg 2 of inspection well cover body 1, inspection well cover.

Fig. 3 is the utility model, the schematic diagram when having flood that the inspection well cover of leg is increased by the inspection shaft internal pressure to back down.Wherein: the leg 2 of inspection well cover body 1, inspection well cover, the flood 3 that backs down inspection well cover, inspection shaft 4.

Fig. 4 is after flood goes down in inspection shaft, the inspection well cover effect schematic diagram after inspection shaft that automatically falls back: wherein: inspection well cover body 1, inspection shaft 4.

The specific embodiment:

As Fig. 1, Fig. 2, shown in Figure 3: when the flood that inspection well cover body 1 is increased by inspection shaft 4 internal pressures backs down, because the leg of inspection well cover 2 abuts against on the inwall of inspection shaft 4 surroundings, inspection well cover can be to the surrounding drift of inspection shaft 4 like this, inspection well cover only can rise directly over inspection shaft 4, after flood overflows, impulse force disappears, and inspection well cover just covers on inspection shaft 4 falling directly over inspection shaft 4 under the effect of self gravitation.So do not need that manually removing in addition to seek the inspection well cover that is flushed away covers inspection shaft 4, just can avoid vehicle, pedestrian to fall into 4 li of the inspection shafts that the flood that is increased by the inspection shaft internal pressure backs down inspection well cover.
