Description
Technical field
The utility model relates to a kind of Safety of Coal Mine Production equipment, especially relates to a kind of fully-mechanized mining working automatic dust suppression device by water spray.
Background technology
The dust disaster is the outstanding problem of dust work place safety in production, it is also the major hidden danger that affects Safety of Coal Mine Production, Self-watering dedusting controller can be by continuous, auto spraying, when the depositing dust dedusting, purifying air, can also absorb certain pernicious gas, reducing gas density, improve and administer the dust work environment, is conventional equipment and the critical facility that effectively prevents dust harzard; Hydraulic support is put coal and is moved the important component part that frame is mining technique, and hydraulic support can produce a large amount of dust in moving the frame process putting coal and fall frame, and therefore, hydraulic support must possess automatic water system.
At present, the caving roof coal hydraulic support watering valve group that use in domestic colliery is altered the problems such as liquid, leakage, pipeline is complicated, the life-span is short, maintenance capacity is large because control system exists, oneself falls to indicate watering valve or spray control pipeline easily to cause the bracket jack pressure release when changing, ubiquity security incident hidden danger.
Summary of the invention
For defective and the deficiency that overcomes prior art, the utility model provides a kind of fully-mechanized mining working automatic dust suppression device by water spray, and its powerful, dependable performance is applicable to dust work place and the environment with damp under coal mine.
Fully-mechanized mining working automatic dust suppression device by water spray of the present utility model, it is characterized in that, it comprises infrared transmitter, Mine-used I. S remote-controlled transmitter, device main frame and the infrared receiver, the electrical ball valve that are connected with the device main frame, infrared transmitter is connected with intrinsic safety dc source I, the device main frame is connected with intrinsic safety dc source II, and electrical ball valve is connected with the watering and lowering dust water curtain.
Wherein, described device main frame comprises PLC controller, wireless receiver and the input/output interface circuit that is connected in turn, and wherein, the PLC controller is connected with infrared receiver, and input/output interface circuit is connected with electrical ball valve.Described intrinsic safety dc source I and intrinsic safety dc source II are 12V intrinsic safety dc source.
Fully-mechanized mining working automatic dust suppression device by water spray of the present utility model is made larger improvement to the host circuit system, the power supply of employing intrinsic safety electric source, fully-mechanized mining working automatic dust suppression device by water spray with infrared receiver, infrared transmitter, wireless launcher, electrical ball valve composition, powerful, dependable performance are applicable to dust work place and the environment with damp under coal mine.
The PLC controller of fully-mechanized mining working automatic dust suppression device by water spray of the present utility model can be realized that the fully-mechanized mining working unit is followed the tracks of watering and support watering comprehensive automation is controlled, and need not to change former pilot operated valve device; Some fully mechanized mining supporters are one group, a cover programmable logic controller are set, some wireless launchers, an infrared receiver and a motor operated valve; Every pack support arranges one group of watering and lowering dust water curtain.Adopt bus to connect between each controller, installation infrared transmitter on coal-winning machine carries out unit to the shuttle-scanning formula lock-in control of support watering.
Description of drawings
Fig. 1 is the schematic diagram of the utility model fully-mechanized mining working automatic dust suppression device by water spray.
The specific embodiment
As seen in Figure 1, the utility model relates to a kind of fully-mechanized mining working automatic dust suppression device by water spray, it comprises infrared transmitter, Mine-used I. S remote-controlled transmitter, device main frame and the infrared receiver, the electrical ball valve that are connected with the device main frame, infrared transmitter is connected with intrinsic safety dc source I, the device main frame is connected with intrinsic safety dc source II, and electrical ball valve is connected with the watering and lowering dust water curtain; Described device main frame comprises PLC controller, wireless receiver and the input/output interface circuit that is connected in turn, and wherein, the PLC controller is connected with infrared receiver, and input/output interface circuit is connected with electrical ball valve; Described intrinsic safety dc source I and intrinsic safety dc source II are 12V intrinsic safety dc source.
The PLC controller of fully-mechanized mining working automatic dust suppression device by water spray of the present utility model can be realized that the fully-mechanized mining working unit is followed the tracks of watering and support watering comprehensive automation is controlled, and need not to change former pilot operated valve device; Some fully mechanized mining supporters are one group, a cover programmable logic controller are set, some wireless launchers, an infrared receiver and a motor operated valve; Every pack support arranges one group of watering and lowering dust water curtain.Adopt bus to connect between each controller, installation infrared transmitter on coal-winning machine carries out unit to the shuttle-scanning formula lock-in control of support watering.
Therefore, fully-mechanized mining working automatic dust suppression device by water spray of the present utility model is to be applicable to dust work place and environment, powerful, dependable performance Self-watering dust falling device with damp under coal mine.
