Drive new trend fan through lithium cell group, the maintainer of can being convenient for carries maintenance construction operation department and uses, increases the convenience of carrying the operation, breathes other harmful gas in avoiding the cable shaft, endangers staff's in the pit safety.
As a further improvement of the invention, the fresh air hose is connected with one side of the fresh air mask, the other side of the fresh air mask is provided with a one-way air valve, and the one-way air valve is provided with an expiratory tube. The one-way air valve enables the respiratory air to flow along one direction only, and the backflow phenomenon can not occur.
As a further improvement of the invention, the end of the fresh air hose close to the fresh air mask is provided with a gas rectifier. The gas rectifier changes the irregular high-speed flowing gas flow into the regular slow flowing gas flow, so that the breathing is smoother.
As a further improvement of the invention, a lighting lamp is arranged on the fresh air mask. The lighting lamp can provide illumination for the operation of the maintainer in the electric well.
As a further improvement of the invention, the lower part of the base is provided with a foot seat. The foot seat reduces vibration and improves stability.
As a further improvement of the invention, the lithium battery pack is fixed on the base, and the lithium battery pack, the driving motor, the fresh air fan and the base form a stable tetragonal structure. The stable tetragonal structure makes the whole body more stable.
As a further improvement of the invention, the driving motor is provided with a lifting handle. The handle is convenient for walking and carrying.
As a further improvement of the invention, an air detector is arranged on the fresh air hose near the fresh air fan end. The air detector detects the component concentration of the gas passing through the fresh air hose, so that the safety of the operation of the maintainer going into the well is improved.
Compared with the prior art, the invention has the following beneficial effects: this scheme passes through the lithium cell group and drives the new trend fan, can be convenient for the maintainer to carry and overhaul construction operation department and use, increases to set up air detector and gas rectifier on carrying the convenience new trend hose of operation to connect the new trend face guard. Other harmful gases are prevented from being breathed in the cable well, and the safety of underground workers is prevented from being damaged.
