Anti-theft, waterproof, dustproof and noise-proof well lid

Abstract

The invention discloses an anti-theft, waterproof, dustproof and noise-proof well lid. The well lid comprises a base and an upper well lid; the upper well lid is embedded in the base, the upper surface of the upper well lid and the upper surface of the base are located in the same plane, an elastic steel ring and a sealing ring are arranged between the base and the upper well lid and concentric with the upper well lid, the elastic steel ring is fixed on the base, the sealing ring is fixedly connected with the elastic steel ring, a V-shaped sealing ring which is in communication with the upper well lid is embedded in the surface, in contact with the bottom of the upper well lid, of the base, and the upper well lid is further provided with a locking mechanism which is used for locking the upper well lid and the base tightly; the well lid can be effectively prevented from being stolen, and dust or rainwater is prevented from entering a well and causing unnecessary damage to equipment in the well; the arranged V-shaped sealing ring has a certain elasticity and can ensure that a cushion effect is generated between the base and the upper well lid when vehicles pass through the well lid, the noise is reduced, and meanwhile, the service life of the well lid is prolonged.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of municipal engineering and pre-embedded laying of power cables, in particular to the technical field of manhole covers, in particular to an anti-theft, waterproof, dust-proof and noise-proof manhole cover. [0003] 【Background technique】 [0004] With the increasing number of municipal projects and the acceleration of the pace of modern cities, the facilities of various underground pipe networks have also increased, and the demand for indispensable pipe network channel covers is increasing, such as sewage pipes, water pipes, natural gas pipes, cables Pipelines, communication cable conduits, etc., because there are cables or equipment under the manhole cover, will be stolen by illegal personnel or low-quality personnel, causing economic losses to the country, so the manhole cover must be anti-theft. Traditional well covers have the following defects. 1. In the prior art, most of the well covers are ...

Problems solved by technology

[0004] With the increasing number of municipal projects and the acceleration of the pace of modern cities, the facilities of various underground pipe networks have also increased, and the demand for indispensable pipe network channel covers is increasing, such as sewage pipes, water pipes, natural gas pipes, cables Pipelines, communication cable conduits, etc., because there are cables or equipment under the manhole cover, will be stolen by illegal personnel or people with low quality, causing economic losses to the country, so the manhole cover needs to be anti-theft

Traditional well covers have the following defects. 1. In the prior art, most of the well covers are anti-theft, but most of the anti-theft covers are complex in structure, so it is required to produce high-precision products, so the production equipment requirements are high and the production cost is high; 2) due to the need to open the well cover to the well cover There are usually holes on the surface of the manhole cover for maintenance operations such as equipment or cables. If certain measures are not taken, rainwater or wind and sand will enter the well, causing damage to the equipment and cables in the well. Not only the rough measures for rain and dust prevention are complicated, but also increase 3) Because the manhole covers are all set on the road, vehicles often pass by, and the manhole covers vibrate, resulting in a short service life of the manhole covers, and the annual maintenance cost of the well remains high
