In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the embodiment of the invention provides an intelligent monitoring and control system for a water pump of an underground small water sump, wherein the small water sump comprises a water pumping pool 1 and a sedimentation pool 2, and a water inlet pipe of the water pump is connected with the water pumping pool 1. The gushing water in the coal mine enters the small water sump to be stored, the sludge in the sedimentation tank 2 is deposited at the bottom of the sedimentation tank, and the pumping tank 1 stores the deposited clear water. Here, the water pump is preferably a submersible pump, the pumping pool 1 and the sedimentation pool 2 are paired, preferably, both of them are provided with a plurality of pumps, each pumping pool 1 is connected with a water pump (such as 1#, 2#, … …, N # in fig. 1), and the water outlet pipes of all the water pumps are connected with the same main water outlet pipeline 10.
For example, the size of the water sump is 3m × 3m, the water sump comprises a sedimentation tank and a pumping tank, the water depth is about 1.5 m, and the flow rate is about 100m3/h。
The little sump pump intelligent monitoring in pit and control system of this embodiment mainly includes: the device comprises a liquid level meter 4, a pressure gauge 5 and a control box 6, wherein the liquid level meter 4 is arranged in the water pumping pool 1 and is used for measuring the water level of the water pumping pool 1; the pressure gauge 5 is connected to a water outlet pipe of the water pump and used for measuring the drainage pressure, and a water outlet gate valve K is further arranged on the water outlet pipe of the water pump and used for normal drainage; the control box 6 is arranged beside the water pump and is simultaneously connected with the water pump, the liquid level meter 4 and the pressure gauge 5, and is used for controlling the water pump to start when the water level of the water pumping pool 1 is higher than the lowest water level value, judging whether the drainage pressure is greater than the lowest pressure value after the water pump is started, and controlling the water pump to stop running when the drainage pressure is not greater than the lowest pressure value. Meanwhile, when the water level of the water pumping pool 1 is lower than the lowest water level value, the control box 6 can also automatically control the water pump to stop running, can also send out alarm information (alarm signals such as buzzing and pop-up window display) when the parameters are not in accordance with requirements and the water pump cannot be started or stopped running, and records or uploads the detected parameters which are not in accordance with requirements to the control console 7, and meanwhile, the control console 7 can also send out alarm information (alarm signals such as buzzing and pop-up window display).
In order to avoid too much sludge in the pumping pond and the sedimentation pond to cause frequent starting and stopping of the water pump or blockage, the intelligent monitoring and control system for the underground small sump water pump further comprises an ultrasonic mud-water interface instrument 3. The ultrasonic mud-water interface instrument 3 is arranged in the sedimentation tank 2 and is used for measuring the thickness of sludge at the bottom of the tank in real time, and when the ultrasonic mud-water interface instrument 3 detects that the thickness of the sludge exceeds the maximum thickness value, the control box 6 controls the water pump to stop working.
The working principle of the ultrasonic mud-water interface instrument 3 is that the transducer emits ultrasonic waves in water, the ultrasonic waves emit a beam of wave, the beam of wave returns when the ultrasonic waves touch a mud-water layer, the beam of wave is reflected back to the transducer, and the distance D between an obstacle and the transducer can be obtained according to the round-trip time of the sound waves and the propagation speed of the sound waves in a measured water area. When the height H of the pool is known, the height H of the sludge to the bottom of the pool can be calculated. By measuring the time difference between transmission and reception, the measurement distance is calculated from the propagation speed of the acoustic wave.
