Two-layer well cover capable of being provided with laser gas detection device

Technical Field

The utility model relates to a fixed building technical field.

Background

The manhole cover is a closure to be attached to the top of an entrance or an exit of an underground facility, and can be classified into a gas manhole cover, a sewage manhole cover, an electric manhole cover, a rainwater manhole cover, and the like according to different purposes and administrative affiliations. In the combustible gas valve well detection, in order to realize the remote monitoring of the gas valve well, instruments or equipment are generally required to be installed in the gas valve well, and the installation of the detection instrument equipment is greatly inconvenient because the waterproof treatment is carried out on the wall of the valve well, and the position of a well ladder is narrow. The main reason is that the waterproof part is not allowed to be drilled and nailed, and the improper construction mode can cause the waterproof failure of the gas monitoring valve well.

The well cover is crushed and damaged, which causes serious reduction of the safety of the road and facilities. With the continuous and high-speed development of infrastructure construction in China in recent years, the management of urban well covers is more important, the attention of urban construction to the safety of the well covers is gradually increased, and the application of double-layer well covers in urban underground valve wells is continuously expanded in order to reduce the incidence rate of safety accidents and guarantee the life and property safety of pedestrians.

Double-deck well lid mainly divide into enclosing cover and two layers of well lid, the upper cover at double-deck well lid shifts or damages the back, two layers of well lid can play the buffering and prevent the effect of weighing down, be convenient for to the modernization management of gas well lid, can place the laser gas detection device of gas well lid in the middle of the upper and lower lid, and in the actual installation application process, two layers of well lid self shelters from to the laser rangefinder probe or the sensor production of instrument and equipment, and because the distance is near between enclosing cover and the two layers of well lid, installation space has the limitation. Need one kind can reach the lower equipment of installation in the technique realization of the combustible gas monitoring of gas valve well, have the ventilation again, prevent dust, two layers of well lid of drainage function, the utility model discloses be used for solving above-mentioned problem.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a two-layer well lid capable of being provided with a laser gas detection device, which consists of a well lid edge, a concave inclined plane, a concave bottom surface, a bottom surface through hole and a bottom surface air hole;

the edge of the well lid is in charge of being attached to the edge of the two-layer substrate of the well ring, the perimeter of the edge of the well lid is larger than that of the inner ring of the edge of the two-layer substrate of the well ring, the perimeter of the edge of the well lid is smaller than that of the well ring, and the edge of the well lid can cover the edge of the two-layer substrate of the well ring to ensure that the two-layer well lid cannot fall into the well;

the concave inclined plane is connected with the edge of the well lid and the concave bottom surface;

a bottom surface through hole is formed in the middle of the concave bottom surface; the bottom surface through hole can ensure that the direction of the laser probe vertical to the bottom surface points underground;

the bottom surface air holes are formed in the positions on the two symmetrical sides of the bottom surface through hole, are responsible for filtering rainwater and ventilating and can enable a laser probe for gas detection to be installed nearby the bottom surface air holes instead of pointing underground in the direction perpendicular to the bottom surface, and therefore the bottom surface through hole is a structural characteristic that the laser probe for completing water level determination points underground vertically.

Advantageous effects

The utility model provides a two-layer well cover which can be provided with a laser gas detection device, the two-layer well cover conforms to the relevant technical standard of the two-layer well cover in the double-layer well cover specified by the state, and the two-layer well cover can be produced in large batch; compared with a two-layer well cover of a common double-layer well cover, the two-layer well cover can be provided with a laser gas detection device and a laser water level detection device, and a circular through hole which is easy for laser beam distance measurement and sensor detection is designed in the middle of the two-layer well cover, so that the safety and stability of the operation of the laser water level detection device and the laser gas detection device can be guaranteed; compared with the prior installation equipment such as a valve well wall or a well ladder, the two-layer well cover capable of installing the laser gas detection device provides a safe and stable installation environment for the laser gas detection device and the laser water level detection device, is simple to install and convenient to detach, is favorable for maintenance of workers, and reduces the influence of artificial damage during maintenance.
