Problems solved by technology

Among them, brick wells have high technical requirements for labor (the process cannot be guaranteed and the strength cannot be achieved) and their service life is short; the construction process of cast-in-place reinforced concrete wells is cumbersome, requiring multiple processes such as erecting formwork and binding steel bars; therefore, The traditional well elevation construction takes a long time, requires a large labor force, and the construction is greatly affected by the environment, and the construction quality is difficult to guarantee, and the later maintenance cost is high

Embodiment 1

[0031] For an intelligent detection and air supply device for downhole operation gas in this embodiment, please refer to the attached Figure 1-5 , including the fan turbofan 6 installed on the upper surface of the well casing body 1, the fan turbofan 6 is equipped with a control unit 13 connected to the vehicle-mounted 12V power supply 7, and the left and right sides of the fan turbofan 6 are respectively provided with a first ventilation pipe 9 , the second ventilation pipe 14, the bottom of the first ventilation pipe 9 extends into the working well, and the end of the first ventilation pipe 9 extending into the working well is equipped with a detection unit 8 for detecting whether the gas content in the working well is normal;

[0032] Wherein, a hose 10 is installed at one end of the first ventilation pipe 9, and one end of the hose 10 extends into the working well, and the detection unit 8 is installed on the hose 10;

[0033] In order to facilitate transportation, a hook...

Embodiment 2

[0039] For an intelligent detection and air supply device for downhole operation gas in this embodiment, please refer to the attached Image 6 The difference between this embodiment and Embodiment 1 is that the number of well casing bodies 1 is two, and the two well casing bodies 1 are inserted up and down as a whole, and the plug-in body 2 of the upper well casing body 1 is inserted into the In the circular groove 5 of the well casing body 1 below, the upper surface is flush with the surrounding roads after being inserted up and down.

[0040] During construction, measure the vertical distance d from the wellhead of the original construction well to the road surface. After the two well casing bodies are inserted in phase 1, the upper surface is flush with the road surface.

[0041] When the present invention is used to raise the well neck of a working well, a well casing assembly of a corresponding size can be directly added to the original working well head to adjust the hei...

Abstract

The invention designs an underground operation gas intelligent detection air exhausting and supplying device which is widely applied to cable working well operations and belongs to the technical field of power distribution, operation and maintenance equipment. The device comprises a fan turbofan installed on the upper surface of a well casing body, a control unit connected with a vehicle-mounted 12V power source is installed on the fan turbofan, a first ventilation pipe and a second ventilation pipe are arranged on the left side and the right side of the fan turbofan respectively, and the bottom of the first ventilation pipe extends into a working well. A detection unit used for detecting whether the gas content in the working well is normal or not is installed at the end, extending into the working well, of the first ventilation pipe. The device has the functions of detecting the gas content in the well in real time and automatically judging and starting air exhausting and supplying treatment in the well, and is convenient to install and high in safety coefficient.

Description

technical field [0001] The invention designs an intelligent gas detection exhaust and air supply device for downhole operations, which is widely used in cable well operations and belongs to the technical field of power distribution operation and maintenance equipment. Background technique [0002] The power cable well is mainly set up for the convenience of power supply, communication, cable maintenance and installation of urban underground infrastructure. It is generally installed at pipeline intersections, turns, pipe diameter or slope changes, and at certain distances on straight pipe sections, which is convenient for regular inspection of ancillary structures. Its main function is to cooperate with the long-distance buried power supply of underground pipelines to facilitate the daily cable operation and maintenance and troubleshooting of electric power operation and maintenance personnel. In order to ensure the safety of the downhole operation, the operator must complet...
