Underground engineering air purifier

Abstract

The invention discloses an underground engineering air purifier, which comprising a hole body, wherein a fixing seat is fixed above the hole body, a hydraulic cylinder, a support frame and a hydraulicpump are fixed above the fixing seat, the hydraulic pump is positioned between the hydraulic cylinder and the support frame, a water storage pool is arranged close to the support frame and above thefixing seat, the outer surface wall of the support frame is provided with an AT89S52 controller, a first fixing box is fixed on one end of the support frame, a hydraulic stretching rod is arranged below the first fixing box, a second fixing box is fixed below the hydraulic stretching rod, and a motor is installed inside the second fixing box. According to the present invention, the probes are arranged, the electric stretching rods stretch, the probes beat the inner wall of the hole body to puncture the gas bag formed by harmful gas accumulating, and the active carbon ring adsorbs the harmful gas, such that the problem that the worker touches the gas bag formed by the harmful gases during the underground drilling operation to cause the threat to the personal safety can be avoided.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, and in particular relates to an air purifier for underground engineering. Background technique [0002] Underground engineering refers to the underground civil engineering that goes deep into the ground to develop and utilize underground space resources. It includes underground houses and underground structures, underground railways, highway tunnels, underwater tunnels, underground common trenches and underground passages for street crossings. Underground buildings have significant Different from the characteristics of above-ground buildings, it has good thermal stability and airtightness, has good disaster resistance and protection performance, and has good social and environmental benefits. Underground engineering construction is difficult, and it has high requirements for ventilation and drying. Air cleaners, air cleaners, and air cleaners are called air cleaners, which refer t...
