Description

Automatic drainage device for coal mine sump

Technical Field

The utility model relates to a mining equipment technical field, especially a colliery sump automatic drainage device.

Background

When a coal mine tunnel is tunneled and a working face is mined, accumulated water in a working face crossheading cannot flow out automatically due to uneven fluctuation of a tunnel bottom plate, a temporary water sump needs to be arranged at a low-lying position of the tunnel, and water is drained by a drainage pump. The existing coal mine water sump drainage device mainly takes manual nursing as a standard, and a specially-assigned person cannot perform drainage work due to tension of personnel, and the drainage work is generally taken charge of nearby posts; because the drainage frequency is frequent, an operator also needs to go in and out of the water bin to observe the water storage amount of the water bin so as to drain water in time, but the operator cannot leave the post under the condition that station equipment at the job runs, so that the water cannot be drained in time to cause roadway water accumulation; in addition, the energy of operators is dispersed, so that the operators cannot concentrate on the operation of the work station, and potential safety hazards exist. In addition, in coal mine production, when a large amount of water suddenly flows into a sump, the normal drainage capacity of the sump is inevitably exceeded, the coal mine sump drainage system in the prior art is difficult to monitor the change condition of water flow and give early warning in time, and further difficult to take measures such as immediately finding out reasons and accelerating drainage in time, coal mine flood is often caused, the coal mine flood problem threatens the life safety of coal mine workers, and the development of national economy is severely restricted.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The utility model is described in detail with reference to the accompanying drawings, as shown in fig. 1-6, an automatic drainage device for a coal mine water sump comprises a water sump 1 and a water inlet pipe 8, wherein a fixed slide plate 12, a travel switch I11 and a travel switch II 10 are fixed on the inner side wall of the water sump 1 from low to high in sequence; the upper end of the inner side wall of the water bin 1 is provided with a mounting groove 2, a filter screen 3 is slidably mounted in the mounting groove 2, and a water inlet pipe 8 is positioned above the filter screen 3 and used for filtering inlet water and preventing a water pump 17 from being blocked; a floating body limiting pipe 5 is fixed at the upper end of the filter screen 3, a floating ball 7 is placed in the floating body limiting pipe 5, and a travel switch III 6 is fixed at the upper end of the inner side wall of the floating body limiting pipe 5; an emergency water pump 9 is fixed at the upper end of the filter screen 3; the handle 4 is fixedly arranged at the upper end of the filter screen 3, so that the filter screen 3 is convenient to replace; a sliding chute 13 is formed in the fixed slide way plate 12, a floating block 14 is arranged in the sliding chute 13 in a sliding mode, a supporting column 15 is fixed at the upper end of the floating block 14, and a touch plate 16 is fixed at the upper end of the supporting column 15; a water pump 17 is fixed at the bottom of the water bin 1.
