Description

Automatic drainage control device for underground sump Technical Field The invention relates to the technical field of underground drainage, in particular to an automatic drainage control device for an underground water sump. Background The underground mine underground water sump drainage system is one of core infrastructures for guaranteeing mine safety production, and the running reliability and efficiency of the underground mine underground water sump drainage system are directly related to underground operation safety and production cost. At present, most mines still commonly adopt a traditional manual control mode to operate a water pump for drainage, and the mode has the problems of high labor intensity, lag response, dependence on personnel experience, easy safety accident caused by manual misoperation and the like. To improve the level of drainage automation, automatic drainage systems based on relay circuits or Programmable Logic Controller (PLC) modules have emerged in the prior art. However, most of the systems are controlled by a preset fixed program or a timing mechanism, the control logic of the systems is often independent of real-time and continuous change of the water level in the water bin, and the control logic still has the defect of insufficient direct coupling with the water level change, and the response timeliness, the working condition adaptability and the running economy of the systems are all to be improved. More importantly, the existing electronic control type automatic system generally relies on electronic components such as a water level sensor to acquire a water level signal. Because the underground water environment has high sediment content, turbid water quality and strong corrosiveness, the underwater sensor is in a soaking state for a long time, and is extremely easy to break down due to sediment accumulation coverage, electrode corrosion or signal transmission interference. Once the sensor fails or errors occur, the system misjudges the actual water level in the bin, and drainage can not be started in time when the water level reaches a warning line, or the water pump is burnt out due to long-time no-load running in a low water level state, so that the caused misoperation not only threatens the reliability of the drainage system, but also directly endangers the safety of underground operation. Disclosure of Invention The application provides an underground sump automatic drainage control device, which aims to avoid the failure problem of a common sensor while realizing underground automatic drainage. The application provides an automatic drainage control device for an underground sump, which adopts the following technical scheme: an automatic drainage control device for an underground sump comprises a fixed platform fixed in the underground sump and a vertical guide rod, wherein one end of the guide rod is fixed on the bottom surface of the sump, the other end of the guide rod is connected with the fixed platform, a floating plate is sleeved on the guide rod, a contact joint is arranged on the floating plate, a magnetic type touch switch for controlling the water pump to be started and stopped is arranged on the fixed platform, and the floating plate slides along the guide rod to drive the contact joint to abut against the magnetic type touch switch. Optionally, a supporting rod with adjustable length is arranged on the floating plate, and the contact joint is arranged at the end head of the supporting rod. Optionally, the guide rod is also sleeved with a weight plate, the weight plate is arranged below the floating plate, the density of the weight plate is smaller than that of water, and the weight plate is connected with the floating plate through a steel wire rope. Optionally, a plurality of magnetic attraction joints are further arranged between the fixed platform and the floating plate. In summary, the application has the following beneficial technical effects: The application can automatically open the water pump along with the water level lifting to drain the underground water bin by arranging the floating plate, the magnetic touch switch and the counterweight plate, and the counterweight plate drives the floating plate to automatically disconnect under the action of gravity after the water is drained, thereby reducing manpower, avoiding the defect that the common water level sensor is easy to fail, and realizing high-reliability, low-maintenance and self-adaptive water drainage operation in the true sense.
