Abstract

The utility model provides a higher inspection shaft lid of security when emergent drainage, includes the inspection shaft lid, be provided with the inner cup on the inspection shaft lid, be provided with the hole of falling into water on the inspection shaft lid, the inner cup below is provided with the support column, be provided with emergent hole of falling into water in the inspection shaft lid, be provided with the horizontal pole on the inspection shaft lid inner wall of inner cup below, be provided with the arch on the horizontal pole. Compared with the traditional inspection well cover which needs to be taken down for emergency drainage, the inspection well cover provided by the utility model has the advantages that the water drainage amount can be increased without taking down the inspection well cover during emergency drainage, and the problem that personnel fall risk exists due to the fact that the well mouth is opened is avoided.

Description

Higher inspection shaft lid of security when emergent drainage

Technical Field

The utility model belongs to the technical field of municipal facility inspection wells, and particularly relates to an inspection well cover with higher safety in emergency drainage.

Background

When water accumulation occurs on urban roads due to special conditions such as storm water, an inspection well cover is usually opened to increase the water drainage quantity so as to carry out emergency drainage. However, as the road is submerged, the position of the inspection well cannot be seen, personnel fall easily occurs, and the potential safety hazard is large.

As the Chinese patent utility model is a municipal engineering inspection well cover convenient for drainage, publication number CN112323863A, wherein the inspection well cover comprises a well cover outer ring and a well cover inner cover plate, the well cover inner cover plate is clamped with the inner wall of the well cover outer ring, a well cover drainage groove is formed in the well cover inner cover plate, the municipal engineering inspection well cover convenient for drainage is connected with the well cover outer ring into an integrated structure through the well cover outer ring, the well cover inner cover plate, a supporting device and a warning device, so that the well cover inner cover plate is not easy to lose when the well cover inner cover plate is opened for drainage, the warning device can be erected after the well cover inner cover plate is opened for warning people to prevent people from approaching, and if people fall down carelessly, a water leakage plate is arranged in the well cover outer ring to block the people and prevent the people from falling; firstly, the technology can prevent the cover plate from being opened and lost through the hinged connection of the inner cover plate and the outer ring of the well cover, but the technology has been applied in reality, because the cover plate is limited in opening direction by the scheme, and the hinged part is easy to deform if rolled by a vehicle for a long time, the technology is not widely popularized and used in the industry; meanwhile, in the technology, people can be blocked by the water leakage plate arranged in the outer ring of the well lid to prevent falling, and the warning device warns when the inner cover plate is further erected, so that the falling of people is prevented, but after the inner cover plate of the well lid is opened, the whole well mouth is opened, the purpose of preventing the falling is achieved only by increasing the water leakage plate, so that higher risks exist, if the water leakage plate is likely to have the possibility of loosening and falling because of excessive accumulated water and accumulation, and the situation that the weight of a human body, even the weight of an electric vehicle or an automobile is uncertain and the safety is insufficient can not be carried under the condition of carrying water flow impact; and this designer need dismantle the water board, just can get into the pit and carry out work such as mud clear or circuit repair, adopts well lid water drainage tank design to seem to have increased the displacement at last, but well lid bulk strength can drop, can not bear the vehicle and roll repeatedly, therefore security, commonality are poor.

Disclosure of Invention

Aiming at the technical problems, the utility model provides an inspection well cover with higher safety in emergency drainage, which comprises the following specific technical scheme:

the utility model provides a higher inspection shaft lid of security when emergent drainage, includes the inspection shaft lid, be provided with the inner cup on the inspection shaft lid, be provided with the hole of falling into water on the inspection shaft lid, the inner cup below is provided with the support column, be provided with emergent hole of falling into water in the inspection shaft lid, be provided with the horizontal pole on the inspection shaft lid inner wall of inner cup below, be provided with the arch on the horizontal pole.

Compared with the traditional inspection well cover which needs to be taken down for emergency drainage, the inspection well cover provided by the utility model has the advantages that the water drainage amount can be increased without taking down the inspection well cover during emergency drainage, and the problem that personnel fall risk exists due to the fact that the well mouth is opened is avoided.

description of the embodiments

For the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. It will be understood by those of ordinary skill in the art that the terms described above are in the specific sense of the present utility model. The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1 to 4, an inspection shaft cover with higher safety during emergency drainage comprises an inspection shaft cover 1, wherein an inner cover 2 is arranged on the inspection shaft cover 1, a water falling hole 3 is arranged on the inspection shaft cover 1, a support column 201 is arranged below the inner cover 2, an emergency water falling hole 103 is arranged in the inspection shaft cover 1, a cross rod 101 is arranged on the inner wall of the inspection shaft cover 1 below the inner cover 2, and a protrusion 102 is arranged on the cross rod 101.

As shown in fig. 5, when emergency drainage is performed, a tool is used to hook the small hole in the inner cover 2, the inner cover 2 is rotated to separate the support column 201 from the cross bar 101, the inner cover 2 is dropped, and the cover body is supported by the cross bar 101 to expose the emergency water falling hole 103, so that emergency drainage is performed. The protrusion 102 on the cross bar 101 can prevent the inner cover 2 from rotating due to touching, and the emergency water falling hole 103 is opened accidentally.
