Description

Drainage manhole cover capable of adjusting opening

technical field

The utility model relates to a drainage inspection well cover, in particular to a drainage inspection well cover capable of adjusting openings, and belongs to the technical field of road planning and construction.

Background technique

Due to incomplete consideration of drainage design in urban construction and abnormal climate changes in recent years, some cities often suffer from serious waterlogging after heavy rains. Urban drainage managers will manually open the inspection well cover or the water under the inspection well cover will When the inspection well cover is pushed open, pedestrians or vehicles will be in danger when passing through, and in severe cases, the situation of accidentally falling into the well and causing death will occur.

At present, some places are equipped with nets to prevent people from stepping down in the inspection well. These nets are generally made of metal or non-metal, and people will not fall into the bottom of the well when stepping on the air. The lid needs to be opened, which will still cause certain dangers to pedestrians and vehicles. Although pedestrians will not fall when stepping in, they are easy to fall, and vehicle tires will also cause damage to vehicles when they suddenly encounter pits.

In the prior art, there is a manhole cover with automatic height adjustment, which increases the drainage gap by raising the manhole cover. Most of the drainage methods of this manhole cover with automatic height adjustment need to be controlled by electric power. Therefore, on the one hand, this method increases The mechanism is complex and the reliability is reduced. Second, the power acquisition of the manhole cover is a certain problem. The erection of cables or the use of batteries will increase the economic cost. If batteries are used, the batteries must be charged frequently. Leakage occurs due to factors such as humid working environment, wasting energy, and the maintenance cost is high. When the drainage capacity needs to be improved in rainy weather, because the height of the manhole cover is increased, pedestrians or vehicles often have poor visual effects due to rainy days. Inadvertently touching the raised manhole cover can still cause damage to pedestrians or vehicles.

Contents of the invention

In order to solve the deficiencies of the prior art, the utility model provides a drainage inspection well cover that can adjust the opening, that is, the drainage capacity of the inspection well cover can be adjusted in rainy days, and the sundries can be prevented from falling into the inspection well in sunny days, and the inspection well cover Always maintain a level with the road surface, avoiding the danger of pedestrians or vehicles traveling in rainy days.

The technical scheme adopted in the utility model is:

A drainage manhole cover capable of adjusting openings, comprising an upper manhole cover and a lower manhole cover stacked up and down, a connecting hole is formed at the center of the circle of the upper manhole cover and the lower manhole cover, and the upper manhole cover and the lower manhole cover are passed through the connecting hole The connecting shaft is connected, the upper well cover is connected with the connecting shaft in rotation, the lower well cover is fixedly connected with the connecting shaft, the upper well cover and the lower well cover are formed with drainage holes, and the drainage holes of the upper well cover are connected with the lower well cover by rotating the upper well cover. The drainage holes coincide or do not coincide.

Further, the number of drain holes of the lower manhole cover is greater than or equal to the number of drain holes of the upper manhole cover, and multiple overlapping and penetrating drainage methods of the drain holes of the upper manhole cover and the drain holes of the lower manhole cover can be realized.

Further, there are eight drainage holes of the upper well cover, and twelve drainage holes of the lower well cover. In the initial state, the drainage holes of the upper well cover and the drainage holes of the lower well cover do not overlap, and the upper well cover is rotated to In the first-level drainage state, four drainage holes of the upper manhole cover coincide with four drainage holes of the lower manhole cover to drain water. When the upper manhole cover is turned to the second-level drainage state, the eight drainage holes of the upper manhole cover and the lower manhole cover. Among them, eight drainage holes overlap and run through the drainage, so that the drainage volume can be selected according to the rainfall.

Further, the thickness and diameter of the upper manhole cover and the lower manhole cover are the same, which improves the stability of the overall connection structure.

Further, the diameter of the drainage hole of the upper well cover is 50-100mm, and the diameter of the drainage hole of the lower well cover is 40-90mm.

Further, the diameter of the drainage hole of the upper well cover is larger than the diameter of the drainage hole of the lower well cover.

Further, an orange-red reflective strip is arranged around the drain hole of the lower manhole cover. On a sunny day, if the drain holes on the upper manhole cover and the lower manhole cover are in a coincident and penetrating state, passers-by can observe the lower manhole cover through the drain holes of the upper manhole cover. The light reflected by the orange-red reflective strips around the drain hole prevents passers-by from danger when passing the manhole cover, especially to prevent the crutches used by the elderly or children's feet from falling into the drain hole in the overlapping and penetrating state, improving safety.

Further, a gasket is provided on the connecting shaft between the upper well cover and the lower well cover to reduce the friction between the upper well cover and the lower well cover during the rotation process, so as to facilitate the rotation of the upper well cover.

Further, the connecting shaft includes bolts and nuts, and the bolts and nuts are standard connecting parts, which are convenient for installation and disassembly as well as subsequent maintenance.

The beneficial effect of the utility model is that two manhole covers with the same thickness and diameter are adopted, and the two manhole covers are set up and down and connected at the center of the circle through a connecting shaft. The upper manhole cover can be rotated relative to the lower manhole cover along the connecting shaft. Several drainage holes are arranged according to regular distribution. When it rains, turn the upper well cover so that the drainage holes on the upper well cover overlap with the drainage holes on the lower well cover. Then the inspection well cover can use the overlapped drainage holes to drain water. The well cover makes the drainage hole on the upper well cover and the drainage hole on the lower well cover not overlap, then the inspection well cover can prevent sundries from falling into the inspection well, therefore, the utility model inspection well cover can adjust the drainage capacity of the inspection well cover in rainy days, and can In sunny days, sundries are prevented from falling into the inspection well, and the height of the inspection well cover and the road surface is always kept level, avoiding the danger of pedestrians or vehicles in the process of traveling in rainy days; the utility model only needs to rotate the upper manhole cover to adjust the drain hole on the upper manhole cover in rainy days The size of the drainage hole on the lower manhole cover coincides with that of the manhole cover, so that the drainage of the manhole cover can be adjusted, and the manhole cover will not be raised, and it will always be level with the road surface. It is very safe for pedestrians and vehicles traveling on the road in rainy days, and no special The maintenance and implementation process are simple and convenient, suitable for large-scale promotion and application.
