Abstract
The invention discloses a detection device for the underground sump coal slime sediment deposition, and relates to one set of device used for detecting underground sump coal slime sediment deposition and carrying out data processing. According to the device, the height of the sump coal slime is detected by a positioning detection device so as to convert and calculate the practical coal slime sediment deposition, the problem that dynamic real-time detection of the practical sump coal slime sediment deposition cannot be implemented is solved, and so that the detection device plays an important role in pre-warning and guiding for sump cleaning.
Description
Technical field
The present invention relates to a kind of down-hole water warehouse coal slurry siltation volume pick-up unit.
Background technology
The down-hole water warehouse coal slurry siltation volume how much never have good device for dynamically detecting, the method that adopts at present is the time assessment mostly, according to amount and the time of actual water storage black water, what of the slime content of actual alluvial in the estimation sump, can not Real-Time Monitoring, can not play forewarning function, wait until that often the coal slime siltation volume is excessive in the sump, when having entered in the water distribution The Small Well of main drainage system, a large amount of coal slimes just considers water-house coal mud clearing, and this moment, the coal slime particle caused a large amount of wearing and tearing to main drainage system, even can stop up the water sucking mouth of main drain pump, and jeopardize mine drainage safety, therefore reach when designing upper limit amount when the water-house coal mud precipitation capacity, can badly influence use and the drainage effect of sump, have to be forced to stop using, enable another sump, this brings a lot of troubles for the colliery modern management.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of down-hole water warehouse coal slurry siltation volume pick-up unit is provided, and described a kind of down-hole water warehouse coal slurry siltation volume pick-up unit comprises orientation magnetic ball, dried spring sensor, guide rod, torque sensor, gearing, signal integrated processor; It is characterized in that: the orientation magnetic ball is oblate spheroid, sealing, at least one permanent magnet is arranged in the ball; Dried spring sensor comprises circuit, resistance, dry reed switch, and a plurality of dry reed switch are distributed in the guide rod, and dry reed switch is in off-state, and closed under magneticaction, the height and position of dry reed switch is determined; Guide rod passes the orientation magnetic ball, and the orientation magnetic ball moves freely along guide rod, and the guide rod at right angle setting is in sump ground.
Black water of the present invention and coal slime height detection principle are, several dry reed switch are distributed among the guide rod, dry reed switch is in off-state under the normality, the attraction meeting that runs into permanent magnet when some dry reed switch is closed, resistance in the place in circuit can change, along with the position of the dry reed switch of closure is different, resistance value in the place in circuit is also different, because the magnitude of voltage that circuit is two sections remains unchanged, according to Ohm law, the current value of circuit output also can be different, the resistance of each resistance all equates, therefore the variation of electric current is different variation of resistance number with access in the circuit, and holds step by step variation, the current value in the circuit is transferred to the signal integrated processor.
Pick-up unit utilization of the present invention is along the height of guide rod orientation magnetic ball moving up and down Real-Time Monitoring black water liquid level and coal slime alluvial, solved the problem that the down-hole water warehouse coal slurry siltation volume can't detection of dynamic, for forewarning function has been played in the sump desilting.

Embodiment
Naturally droop under orientation magnetic ball 1 gravitate, gearing starts forward, and orientation magnetic ball 1 is slowly fallen, and this moment, torque sensor 4 and dried spring sensor 2 passed torque signals and current signal back can for respectively signal collection analyzer 18; When orientation magnetic ball 1 touches on the black water 8 interface, because orientation magnetic ball 1 is subject to buoyancy, the torque signals of torque sensor 4 can change, the current signal that this moment, dried spring sensor 2 was passed back also can be some values, because the height and position of dry reed switch is to set in advance, therefore these two signal values combine, can analyze the liquid level of black water 8, after orientation magnetic ball 1 submerges in the black water fully, continue to sink, when the orientation magnetic ball sinks down into the upper interface of coal slime silting 9, torque signals reaches the regulation null value, the regulation null value is that the pre-determined buoyancy that is subject to when the orientation magnetic ball is when reaching certain value, think that solid content is enough high in the black water, can assert and touch coal slime silting 9, when torque signals reaches the regulation null value, dried spring sensor 2 can be passed current signal value back, and at this moment, one-time detection finishes, the gearing counter-rotating is lifted out the coal slime water surface with the orientation magnetic ball, carry out secondary decline and detect, pass through repeated detection, and the signal that each time gathers all is transferred to analyzer 18 in the set of signals, determine the height of coal slime alluvial, because the length of sump and wide be fixed value, therefore, analyzer 18 calculates coal slime siltation volume in the sump in the set of signals.
