Described frequency variator connects municipal power supply, and is connected with booster by guide line, with the control local ventilation
The machine rotating speed;
Further, described booster also directly links to each other with municipal power supply by contactor.When control system broke down, frequency variator was not worked, and this moment, contactor directly accessed power supply with booster, guaranteed the running of booster, guaranteed downhole safety.
Further, also comprise upper-position unit, the singlechip controller of described upper-position unit while with a plurality of described ventilated energy-saving automatic speed regulations unit communicates to connect, in order to the Operational Limits that receives and preserve singlechip controller sends in each ventilated energy-saving automatic speed regulation unit temperature parameter, gas density parameter, Excavation Length parameter and booster, when abnormal conditions occurring, control respectively each ventilated energy-saving automatic speed regulation unit by artificial input parameter.
Further, described frequency variator and singlechip controller concentrated setting are in a control box, and be installed in booster top, between booster and control box, be provided with ventilation duct, one end of described ventilation duct is fixed on the exhaust outlet of booster, and aligning exhaust outlet, the other end are connected on the control box, aim at the radiating fin of frequency variator.Its good heat dissipation effect can make frequency variator normally move in the down-hole, so that more convenient when carrying out driving face transfer installation, improved working efficiency.
The energy-conservation automatic speed regulation system of mine ventilation described in the utility model, by each position mounting temperature sensor, firedamp sensor and the Excavation Length sensor in the down-hole, send the real time data of gas density, temperature and the Excavation Length of each position of down-hole to singlechip controller, singlechip controller makes decisions according to the decision making algorithm that is set in the singlechip controller, so that frequency variator is controlled, thereby reach the control booster, regulate the purpose of wind speed.When the Automatic control of single chip microcomputer frequency variator breaks down, because the utility model is provided with upper-position unit, control respectively each singlechip controller by artificial input parameters, thereby the control frequency variator reaches the control blower fan, regulates the purpose of wind speed.The utility model can be in good time monitor well under situation, and effectively control the rotating speed of booster according to the situation of down-hole, effectively avoided the down-hole air quantity not satisfy the demands, or the down-hole air quantity is excessive and cause the problem of energy waste.
