Description
Technical field
The utility model relates to a kind of underground coal mine automatic drainage control device.
Background technique
Water is often assembled by the low-lying place of underground coal mine, the height if water level of leaving rises and do not carry out draining, tunnel, low-lying place may be caused not had by water logging, impassable personnel, and hinder distinguished and admirable, cause ventilation accident.Need to arrange special messenger's draining, or automatic drainage control device is installed.Conventional automatic drainage control device, generally with the water level detected to control magnetic starter start and stop water pump.
Because underground air is moist, particularly water place, situation is more serious.The sensor of sensed water level signal and circuit thereof often can break down; even if cause water level to transfinite can not start pumping drainage, flood tunnel, even flood drainage control equipment; cause cannot carrying out draining in the short time, normally carrying out of impact safety in production.
Underground coal mine need arrange self-draining place, and often away from the tunnel of getting working face, water flow is relatively stable, possesses the condition of draining at regular time and quantity.
Model utility content
The technical problems to be solved in the utility model is the above-mentioned defect how overcoming prior art, provides a kind of underground coal mine automatic drainage control device.
For solving the problems of the technologies described above, this underground coal mine automatic drainage control device comprises floating ball type liquid level control mechanism, this floating ball type liquid level control mechanism comprises ball float, guide rod, high-order proximity switch and low level proximity switch, high-order proximity switch and low level proximity switch and protection transformer, comprehensive protection device composition draining pump control circuit, it is characterized in that: it also comprises gauge and stay cord, described guide rod is fixed on gauge, and extend below gauge, described ball float is enclosed within the guide rod below gauge, gauge top is provided with a pulley, described stay cord strides across pulley, its one end ties up on ball float, the other end ties up on gauge counter weight behind, high-order proximity switch and low level proximity switch are separately fixed on gauge, described stay cord is also provided with a tinsel, this tinsel is between high-order proximity switch and low level proximity switch.
Ball float is the solid plastic block of band two pilot holes, is arranged on non-metal guide post by pilot hole, and guaranteeing can not be washed away.When being in highest water level, ball float is blocked by gauge, can not be upwards floating again, is kept, until water level decreasing the high water level Chief Signal Boatswain time.The gravity of ball float own is comparatively large, because entering impurity in pilot hole or stay pulley frictional force is stuck greatly, can not truly can reflect the decline of water level when guaranteeing water level decreasing.
At the opposite side of pulley, stay cord is fixed with counter weight, stay cord energy precise motion when guaranteed water level goes up.With the tinsel of arrow, be fixed on stay cord, move up and down with SEA LEVEL VARIATION, arrow refers on the graduated scale of mark, the height of accurate indicated water level.Metal length of a film 50mm, guarantees that water level fluctuations can not have influence on the Signal reception of high-low water level proximity switch.Two proximity switches are separately fixed at high water level and low water level position, and when tinsel is in high water level or low water level position, proximity switch is often made war closed, for magnetic starter sends signal.
As optimization, described guide rod is made up of two vertical guide rods, and two vertical guide rods are fixed on gauge, and form memorial archway formula gauge, the relative distance of directional post and memorial archway formula gauge can regulate.Memorial archway formula gauge is provided with graduation line, and graduation line and high-low position proximity switch lay respectively at memorial archway formula gauge both sides.
As optimization, described draining pump control circuit also comprises timing controller, closely controls enable switch, nearly control closing switch and far and near control diverter switch.
The utility model underground coal mine automatic drainage control device has timing drainage and high-low water level Auto-drainage two kinds of independent control modes, a kind of control mode is caused to lose efficacy even if sensor or circuit break down, another control mode still normally can control draining, ensure that draining safety.
Use this device to carry out Auto-drainage, water discharge time needed for every day can be determined according to actual measurement water displacement, and can be set to the 23:00-7:00 electric-net valley phase and carry out draining, realize the object of power cost saving.For the place of classification draining, can be set poor the regular hour, realize water pump successively delayed startup, be suitable for drainage underground.
