Drainage assisting type theft-proof drainage well lid with adjustable positional altitude

Abstract

The invention discloses a drainage assisting type theft-proof drainage well lid with an adjustable positional altitude. The drainage assisting type theft-proof drainage well lid with the adjustable positional altitude is installed on a drainage well. Wedge-shaped locking holes are formed in the wall of the drainage well. The drainage assisting type theft-proof drainage well lid comprises a well lid body, a supporting column, a main gear plate, wedge blocks and a pinion control lever, wherein a lock hole is formed in a position, deviated from the center, of the well lid body, the supporting column is fixedly connected with the well lid body and is provided with a taper hole support and a guide groove, the lower end of the supporting column is sleeved with the main gear plate in a rotary mode, planar threads are arranged on the lower plane of the main gear plate, the wedge blocks are provided with guide rods which are inserted into the guide grooves, teeth meshed with the planar threads and wedge-shaped parts which are matched with the locking holes, the pinion control lever is inserted into the lock hole, a pinion at the bottom end of the pinion control lever is meshed with the main gear plate and drives the wedges to move in the radial direction through the main gear plate, the wedges slide along the oblique plane of the lock hole to rise and fall, and then the well lid body is driven to rise and fall correspondingly through the guide rods, the guide groove and the supporting columns. The drainage assisting type theft-proof drainage well lid with the adjustable positional altitude can be adapted to road altitude changes caused by various factors and has the burglary prevention function as well as the drainage assisting function.

Description

technical field [0001] The invention relates to a municipal road facility, in particular to a drainage-aiding anti-theft sewer cover capable of adapting to different road surface heights and adjustable in position and height, and belongs to the technical field of drainage. Background technique [0002] At present, with the rapid economic and social development, the urbanization process is also accelerating. The sewer well is a common and important indispensable drainage facility on municipal roads, but around this simple device, unexpected accidents often occur, and some even endanger people's property and life. Installed manhole covers are frequently stolen, causing vehicles to be stuck, innocent passers-by injured, and even fatal. In addition, after the manhole cover is lost, underground communication cables and other important facilities related to urban operations and even national security will be threatened. Great threat. Due to the short construction period and low ...

AI Technical Summary

Problems solved by technology

Installed manhole covers are frequently stolen, causing vehicles to be stuck, innocent passers-by injured, and even fatal. In addition, after the manhole cover is lost, underground communication cables and other important facilities related to urban operations and even national security will be threatened. great threat

Due to the short construction period and low construction quality of the road, the road subsidence often occurs shortly after the completion of the construction, causing the sewer cover to protrude from the road, causing traffic hazards

The urban drainage problem in summer has gradually become a chronic problem. When encountering heavy rain or flood, it is often the case that the manhole cover is completely opened directly for drainage, but doing so greatly threatens the personal and property safety of residents. It is not an isolated case of people falling into uncovered sewers and being washed away

[0003] At present, people have adopted some protective measures such as hinges and locks. These methods are either difficult to operate, high in cost, or easy to rust, and cannot adapt to the settlement of the road surface, and it is difficult to achieve convenient drainage.
