Abstract

The invention discloses an inverter circuit of a fan driving module of a tunnel dedusting car. The tunnel dedusting car comprises a sealed type compartment separated into a power distribution chamber and a dedusting chamber, a sealing door and a heat dissipation opening are formed in the power distribution chamber, a power distribution device is configured in the power distribution chamber, and the power distribution device comprises an electric generator, a power distribution cabinet and a fan for heat dissipation. The power distribution cabinet is connected with the electric generator for power extraction, the fan for heat dissipation is connected with the power distribution cabinet through the driving module, and the driving module comprises a rectification circuit, a filter circuit and the inverter circuit. The inverter circuit comprises a power tube driving chip which is connected to the power output end of a microprocessor, and therefore corresponding power tubes can be driven to be alternatively switched on and switched off according to pulse width modulation signals output by a microprocessor of the microprocessor circuit . The tunnel dedusting car and accessory facilities of the car can meet the dedusting requirements of the tunnel construction environment well.

Description

technical field [0001] The invention relates to dust removal equipment, in particular to a tunnel dust removal vehicle and its auxiliary facilities. Background technique [0002] The problem of dust in tunnel construction is very prominent, which not only seriously affects the environment, but also is not conducive to the health of workers. Therefore, effective dust removal methods must be adopted. It is conceivable that for a dust removal system with better effect, it not only costs a lot of money, but also takes a lot of man-hours, which greatly weakens the enthusiasm of the construction unit for dust removal treatment. In view of the defect that the existing dust removal system is difficult to promote in the tunnel construction environment, it is necessary to build a low-cost, recyclable mobile dust removal equipment system and auxiliary facilities to meet the dust removal needs of the tunnel construction environment. Contents of the invention [0003] Aiming at the de...
