Intelligent digital pressure gauge for assisting drainage of well lid and monitoring damage

Abstract

The invention discloses an intelligent digital pressure gauge for assisting drainage of a well lid and monitoring damage. The pressure gauge comprises a lid body, the interior of the lid body is provided with a vertically-through working cavity, gear shafts which are symmetrical in the front-back direction are rotatably installed between the left wall and the right wall in the working cavity, and the gear shafts are fixedly provided with gears. An outer tooth column in sliding fit with the left wall and the right wall of the working cavity is engaged between the gears, a communicating cavity penetrating up and down is formed in the outer tooth column, an annular limiting ring is fixedly arranged on the inner side wall of the communicating cavity, and a rotating rod is rotatably installed on the inner side wall of the communicating cavity; and the rotating rod extends rightwards into the outer tooth column and is connected with a driving motor embedded in the outer tooth column, and the well lid is fixedly arranged on the rotating rod. The gravity sensor and the water flow sensor are matched to detect whether foreign matter accumulation and blockage exist or not, then opening is performed, meanwhile, the pressure gauge is isolated to remind pedestrians to bypass, the drainage speed is increased, and troubles caused by water accumulation are avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent digital pressure gauges, in particular to an intelligent digital pressure gauge for assisting well cover drainage and monitoring damage. Background technique [0002] Intelligent digital pressure gauges are widely used in petroleum, chemical fiber, plastic, rubber and other industries to measure and control pressure. Generally, it has upper and lower pressure limit alarms, which can be output by relay contacts, voltage pulse outputs, and triac-driven trigger outputs; two-way constant current (or constant pressure) outputs and other functions. Manhole covers are used to cover roads or deep wells in homes to prevent If people or objects fall, because the manhole cover is a metal product, criminals will steal it. The traditional manhole cover has the following disadvantages: [0003] 1. The traditional manhole cover is not convenient to protect the manhole cover itself. The traditional manhole c...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional manhole cover is not convenient to protect the manhole cover itself. The traditional manhole cover is positioned so that the stolen manhole cover can be retrieved, but there is still no risk of being stolen;

[0004] 2. The traditional manhole cover is inconvenient to detect and control the pressure in the well, because the pressure in the well is too high, it will make it difficult to open the manhole cover and it is not convenient for maintenance;

[0005] 3. The traditional manhole cover is not convenient for self-detection. Because the manhole cover is exposed and leaks all the year round, it is easy to be damaged. When it is damaged, it is easy for someone to fall into the well and cause tragedy;

[0006] 4. The traditional manhole cover is not convenient for dredging and detecting the blocked pipeline opening, which makes the road too much water and causes unnecessary troubles
