Abstract

The utility model relates to a closing device for a water prevention sluice gate for mines, particularly an immediately closing device for all the classes of water prevention sluice gates under mines. The utility model is composed of a grate door, a moving steel rail, a quickly demounted mechanism of a moving string, a closing mechanism of a sluice gate and a hydraulic station which are orderly arranged in a wall. The upper part of the grate door is provided with a grate, and the lower part is provided with an integral steel plate. The moving steel rail and the quickly demounted mechanism of the moving string are composed of the moving steel rail, a roller, a wire cable and a hydraulic motor. A closing mechanism for the water prevention sluice gate is composed of a connecting rod mechanism and an oil cylinder. Each power source comes from the hydraulic station. When the water inrush is generated, the hydraulic station works, and the grate door is closed firstly; at this time, workers are evacuated from the moving grate. Then the moving steel rail and the string are demounted. Finally, the water prevention sluice gate is closed. The utility model with the advantage of reasonable and scientific structure can effectively prevent sundries, such as coal slurry, mine timber, sand, stones, etc., from blocking the water prevention sluice gate, can quickly demount the steel rail and the string, and can control remotely. Because the whole closing operation can be completed in 2.5 min, the danger of workers in field operation is avoided, and the safety of mines and workers can be ensured.

Description

Mine water dam shutoff device

Technical field the utility model relates to the device that all kinds of water dams under the mine cut out immediately.

The background technology water dam is to guarantee one of visual plant that mine safety is produced, all kinds of water dams of existing use all do not have mechanical shutoff device, when gushing water, close, bring danger for the personnel of closing by artificial scene, this be because, 1, closes water dam and need at first close the preceding double-edged fine-toothed comb door of water dam, and rail, movable stringing before the dismounting water dam, do these needs of work time, and when gushing water, escape is first selection, and people often have little time to finish above-mentioned work; 2, when gushing water, current dash foreign material such as the coal slime in the tunnel, mine timber, sandstone to water dam, and the section of gate is littler than drift section, causes the foreign material alluvial around water dam, and water dam can't cut out, and also difficulty is tight even close.Water bursting in mine floods a level at least, and heavy then whole mine is submerged, and causes extremely heavy loss to national wealth.

The summary of the invention the purpose of this utility model is at above-mentioned present situation, aims to provide a kind of mine water dam shutoff device that water dam can cut out immediately when gushing water.

The implementation of the utility model purpose is, mine water dam shutoff device, by the double-edged fine-toothed comb door 2 that is contained in wall 1 successively, movable rail and adjustable shelf linear speed are torn mechanism open, the closing organ of water dam and Hydraulic Station 11 are formed, double-edged fine-toothed comb door top is grid 12, the bottom is an integral plate 13, connect hydraulic jack 3 on the double-edged fine-toothed comb door, movable rail and adjustable shelf linear speed are torn mechanism open by the fixedly rail that is contained in the tunnel, being 45 ° of movable rail that dock 14 with fixing rail forms, movable rail places on the bearing pin 15, the bearing pin two ends are connected with cylinder 9 with wire rope 16, cylinder 9 is driven by hydraulic motor 10, the closing organ of water dam is contained on the bearing 7 in tunnel, pedestal mounted hydraulic jack 6 drives water dam and opens, the linkage 4 that closes, hydraulic jack 3,6, hydraulic motor 10 provides power source by Hydraulic Station 11.

When gushing water takes place when, Hydraulic Station 11 work, hydraulic jack 3 is closed the double-edged fine-toothed comb door, at this moment, grid 12 is all opened to the inflow side, and the personnel of being beneficial to cross over steel plate 13, then hydraulic motor 10 work, driving speed is torn mechanism open movable rail, movable stringing is drawn in the water dam hole simultaneously, at this moment, close the obstacle full scale clearance of water dam, treat personnel's general evacuation after, hydraulic jack 6 work, drive link mechanism 4 closes water dam.

The utility model is scientific and reasonable for structure, can effectively stop foreign material stopping such as coal slime, mine timber, sandstone water dam, can remove rail, stringing rapidly, the energy Long-distance Control, in the 2.5min clock, finish the Close All operation, avoid the danger of personnel's execute-in-places, guaranteed mine and personnel's safety.

The utility model is scientific and reasonable for structure, can effectively stop foreign material such as coal slime in the tunnel, mine timber, sandstone to the stopping of water dam, can immediately water dam cut out when gushing water, guarantees mine and personnel's safety.

The utility model also is applicable in the underground construction of mine, tunnel and waterproof, anti-mud-rock flow.
