Description
Technical field
The utility model relates to monitoring mining technical field, specifically a kind of underground coal mine air duct apparatus for monitoring working state.
Background technology
At present, all local fan of heading face in down-hole all achieve " two fans, Dual-power automatic switching ", and have installed the electromechanical equipment start-stop sensor of monitoring the service behavior of booster.But electromechanical equipment start-stop sensor can only play detection effect to the power supply whether working properly of active and standby ventilation fan, to occurring that air duct disconnects or the air duct breakage phenomenon such as serious of leaking out but cannot monitor, therefore need air duct working state monitoring sensor is installed.But existing air duct working state monitoring sensor is all mechanical button formula, because underground air is moist, temperature is higher in production practices, the monitoring sensor of mechanical button formula is easily aging and get rusty, switch easily blocks bullet not, make monitoring system still show normally, correctly can not reflect the working condition of air duct.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, and provides a kind of underground coal mine air duct apparatus for monitoring working state.
The utility model is achieved by the following technical solution:
A kind of underground coal mine air duct duty monitoring arrangement, comprises left curved shape folder, right cramp frame, tongue tube, L shape fixed head and magnet piece; The top of left curved shape folder and the top of right cramp frame are articulated and connected (cramp frame is half-circle-arc shape, and left and right cramp frame can support into circular around pin joint); The short slab end winding support of L shape fixed head is at the top of right cramp frame, tongue tube is fixed on the long slab inside wall of L shape fixed head, magnet piece be fixed on left curved shape folder top, and when left and right cramp frame strut formation circular time, tongue tube is positioned at directly over magnet piece.Tongue tube is a kind of well known device, its operating principle is very simple, the magnetizable reed of two panels end points place overlap, be sealed in a glass tube, distance only about several micron that two reeds are separated, highly purified inert gas is filled with in glass tube, when not yet operating, two panels reed does not contact, additional magnetic field makes to produce different polarity near two panels reed endpoint location, and the reed of result two panels opposed polarity will be attracted each other and close.Technology can make the changeover module of very reduced size volume according to this, and switch speed very fast and have very excellent reliability.
The utility model device utilizes permanent magnetic iron assembly and a set of installed body of dry-reed tube component (left and right cramp frame) to couple together, and make installed body (left and right cramp frame) clamp air duct, along with bulging and the depression of air duct, installed body (left and right cramp frame) namely opens or draws close; Thus make magnet and tongue tube close to or away from, namely drive the contact in tongue tube to disconnect or closed, communicating circuit often opened or conducting, reaches the object of the state of monitoring air duct work with this.
Specific works principle is: when air quantity in booster air duct is sufficient, left and right cramp frame is softened, the magnet promoting to be fixed on left curved shape ogival sections is close to each other with the tongue tube being fixed on right cramp frame top, when the two is close to certain distance, make dry-reed tube switch action, export passive contact signal after switch motion for the collection of downhole monitoring substation.The signal of outstation collection is delivered to front end processor by transmission cable, enters central station, and central station can grasp the air duct air feed situation of booster in real time, coordinates start-stop sensor, comprehensively monitors blower fan.Effectively can reduce because air quantity in air duct is little, the security incident of leaking out or booster breaks down and causes appears in air duct.
Further, the long slab of L shape fixed head offers screwed hole, and screwed hole internal thread is connected with gag lever post, and when left and right cramp frame strut formed circular time, the top that the bottom overhead of gag lever post presss from both sides at left curved shape.The top that gag lever post overhead presss from both sides at left curved shape, what can control left and right cramp frame struts degree, and left and right cramp frame can be adjusted by the position of rotary stopper bar in the long slab of L shape fixed head strut degree.
The long slab lateral wall of L shape fixed head is fixed with suspension ring, thus optimizes the utility model device further.
The design of the utility model air duct duty monitoring arrangement is ingenious, structure is simple, facilitate sensitive, the utility model air duct duty monitoring arrangement is not only well positioned to meet production requirement, and solve mechanical button formula monitoring sensor and very easily damage, the problems such as application life is short, and in use, artificial power-off, stop the operations such as blower fan work, all can normally show, can accurately and timely monitor in real time blower fan service behavior, and Signal transmissions is rapider, sensitive, central station effectively can gather the feedback data of air duct duty monitoring arrangement in real time, thus serve good safe effect.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
In figure: 1-left curved shape folder, the right cramp frame of 2-, 3-tongue tube, 4-L shape fixed head, 5-magnet piece, 6-gag lever post, 7-suspension ring.
Detailed description of the invention
Do to state further to the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, 2, a kind of underground coal mine air duct duty monitoring arrangement, comprises left curved shape folder 1, right cramp frame 2, tongue tube 3, L shape fixed head 4 and magnet piece 5; The left curved shape folder top of 1 and the top of right cramp frame 2 are articulated and connected; The short slab end winding support of L shape fixed head 4 is at the top of right cramp frame 2, tongue tube 3 is fixed on the long slab inside wall of L shape fixed head 4, magnet piece 5 be fixed on left curved shape folder 1 top, and when left and right cramp frame 1,2 strut formation circular time, tongue tube 3 is positioned at directly over magnet piece 5.
During concrete enforcement, the long slab of L shape fixed head 4 offers screwed hole, and screwed hole internal thread is connected with gag lever post 6, and when left and right cramp frame 1,2 strut formed circular time, the bottom overhead of gag lever post 6 is at the top of left curved shape folder 1.The long slab lateral wall of L shape fixed head 4 is fixed with suspension ring 7.
