Abstract
The utility model relates to a fully automatic water supply device for the explosion proof sink liquid level under the coal mine. The device consists of a sink, a water level sensor, a pressure sensor, a water pipe, an electric ball valve, a relay and a programmable controller. The sink is provided with a pressure sensor, and the water level sensor is arranged aside the sink and connected with display by lead. The electric ball valve is installed on the water pipe between the water pipes so as to control feeding of the sink. The pressure sensor, the water level sensor and the electric ball valve are threaded relative relays and connected with the programmable controller by lead. The programmable controller processes signals of each information terminals and conducts start and stop in accord with preset process. At the same time of assuring normal water level of each sink, the utility model can spray and dedust. The utility model of simple structure and easy operation can automatically preserve water level of the sink under coal mine.
Description
Technical field:
The utility model relates to water supply installation, relates in particular to flame proof tank liquid level full-automatic water supply device under the coal mine.
Background technology:
Supply water under the coal mine of prior art, adopt the Attended mode form more, automatic performance is poor, often because the water level deficiency of water intaking position causes work unreliable, influences normal depositing dust and eliminates smoke, and incurs loss through delay normally carrying out of digging.Especially because timely and effectively water spray dust, can increase a lot to the down-hole such as the quick-fried unsafe factor that waits of dirt.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and flame proof tank liquid level full-automatic water supply device under a kind of coal mine is provided, and realizes keeping automatically under safe condition under the coal mine tank liquid level and full automatic water supply.
Flame proof tank liquid level full-automatic water supply device under the coal mine described in the utility model, including tank, pressure sensor, liquid level sensor, electrical ball valve, relay, programmable controller and water supply line forms, said tank is a main component of the present utility model, with single tank permutation and combination.Be provided with pressure sensor in each tank, each tank side is provided with liquid level sensor, is connected with display by lead.Said water supply line is the total pipeline that the utility model supplies water in tank, on the pipeline that connects each group tank, is provided with electrical ball valve, in order to control amount of makeup water in tank at any time.Said pressure sensor, liquid level sensor and electrical ball valve, all pass through relay separately, be connected with controller by lead, by controller the information of each information end is handled, start and shutoff operation by the program of setting, in the normal liquid level in guaranteeing each tank, guarantee to carry out according to the actual needs atomizing de-dusting.Electric devices such as relay of the present utility model and electrical ball valve all adopt the hermetically-sealed construction of intrinsic safety type, guarantee safe and reliable.
Use flame proof tank liquid level full-automatic water supply device under the coal mine described in the utility model, can guarantee that the coal mine lower flume keeps liquid level automatically, especially the utility model overall structure is simple, and is easy for operation.
