Due to the limited capacity of the suction well, if the water level is not observed in time, the danger that the water level is over-limit and the water pump cannot be started to drain water is caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to overcome prior art's above-mentioned defect, provide a water sucking well water level monitoring alarm device.

In order to solve the technical problem, the water level monitoring and alarming device of the suction well comprises a floating ball, a counterweight hammer, a pull rope and a memorial archway type water level scale, and is characterized in that: the device comprises a housing, a housing door type water level scale, a fixed pulley, a floating ball, a counterweight hammer, a pull rope, a permanent magnet indicating block and a counterweight hammer, wherein the housing door type water level scale is arranged on the housing door type water level scale; the floating ball is correspondingly sleeved on the two nonmetal guide posts through the two guide holes; the high water level approach switch and the low water level approach switch are both reed switch normally open switches, the high water level approach switch and the low water level approach switch are respectively provided with a light emitting diode and a buzzer, and are respectively connected with the light emitting diode and the buzzer in series to form a high water level alarm circuit and a low water level alarm circuit, the high water level alarm circuit and the low water level alarm circuit are connected with a mine intrinsic safety direct current power supply after being connected in parallel, and the mine intrinsic safety direct current power supply supplies power.

The floating ball is arranged on the nonmetal guide post through the guide hole, so that the floating ball is ensured not to be washed away by water. The gravity of the floating ball is large, so that impurities entering the guide hole or the friction force of the pull rope pulley is prevented from being blocked when the water level descends, and the descending of the water level can be reflected truly. The pull rope is fixed with a counterweight hammer, so that the pull rope can accurately move when the water level rises. The metal arrow is fixed on the pull rope and moves up and down along with the change of the water level, and the arrow points on the scale marked with scales to accurately indicate the height of the water level. The length of the arrow of the metal sheet is 50mm, so that the water level fluctuation can not influence the signal receiving of the high and low water level proximity switch.

When the water level in the water absorption well reaches the upper limit, the permanent magnet block on the permanent magnet indicating block approaches the high water level approach switch, the high water level alarm circuit is connected, and an audible and visual alarm is sent out to be processed by workers. If the water level in the water absorption well reaches the lower limit, the permanent magnet block on the permanent magnet indicating block approaches the low water level approach switch, the low water level alarm circuit is switched on, and an audible and visual alarm is given out to be processed by workers.

The design is simple in structure and convenient to use.

And as optimization, a manual switch is further arranged on a lead between the mining intrinsic safety direct-current power supply and the high water level alarm circuit and the low water level alarm circuit. The design is convenient for switching.

The utility model discloses water level monitoring alarm device of water absorption well can carry out the monitoring and the warning of height water level, can realize that the pump house absorbs water the water level monitoring of positions such as well, reminds operating personnel in time to carry out the drainage, and this device still can be connected with water pump magnetic starter after expanding simultaneously, realizes that other mining areas water pump is automatic high water level starts, low water level shuts down.

The device's operation has reduced the artifical intensity of labour who patrols and examines the water level, effectively ensures the safe and reliable of central pump house owner drainage system simultaneously and reports to the police the operation under the emergency situation, has certain social. The water level monitoring device is widely applicable to various drainage points or places needing water level monitoring, such as a coal mine central pump room.
