Detailed Description

The utility model is described in further detail below with reference to the attached drawings and detailed description:

as shown in fig. 1, an underground automatic drainage system comprises a water sump 1 and a sedimentation tank 8 which are communicated with each other through a filter screen 9 in the pit, wherein the water sump 1 conveys mine water to a drainage pipe network 3 through a main drainage pump 2 for external drainage, the sedimentation tank 8 is provided with an accident water pump 5 for drainage, a water level detector and a floating ball liquid level meter 10 are respectively arranged in the water sump 1 and the sedimentation tank 8, the water level detector and the floating ball liquid level meter 10 are electrically connected with a controller 4, and the controller 4 is electrically connected with the accident water pump 5 and the main drainage pump 2.

As shown in fig. 1, the water level detector of the sump 1 includes a low level detector 6 and a high level detector 7, which are electrically connected to the controller 4, respectively.

As shown in fig. 2, the floating ball liquid level meter 10 is arranged at the top of the filter screen 9 and fixed by side mounting, and the position of the floating ball liquid level meter 10 is 20-30cm higher than that of the high-level detector 7.

As shown in fig. 2, the floating ball level gauge 10 is installed at the upper part of the outer side fixing frame of the filter screen 9.

As shown in fig. 1, the accident water pump 5 conveys accumulated water in the sedimentation tank 8 to the drainage pipe network 3 for external drainage.

As shown in fig. 1, the controller 4 is electrically connected with an alarm 11 for alarming the high water level of the sedimentation tank 8.

The embodiment of the utility model provides an implementation principle of an underground automatic drainage system, which comprises the following steps:

the mine accumulated water is collected into a sedimentation tank 8 through a pipeline for filtering and sedimentation, is filtered and intercepted by a filter screen 9 and enters into a water sump 1 for storage, when the water level in the water sump 1 reaches a high-level detector 7, the high-level detector 7 transmits a signal to a controller 4, and the controller 4 controls a main drainage pump 2 to start to be conveyed to the outside of a drainage pipe network 3 for drainage;
