Abstract
The utility model discloses an inside-outside double-control water curtain control system under a coal mine well. A water supply pipeline is respectively communicated with a left branch pipe and a right branch pipe, the portions, at the left and the right of a water curtain, of the left branch pipe are provided with a first valve and a second valve respectively, the portions, at the left and the right of the water curtain, of the right branch pipe are provided with a third valve and a fourth valve respectively, the first valve and the third valve are linkage valves, and the second valve and the fourth valve are linkage valves. The linkage valves are controlled in a mechanical mode, it can be guaranteed that a water channel can be controlled to be connected and disconnected on the two sides of the water curtain, and the problem that when passing from under the water curtain, a worker makes contact with the water curtain and accordingly clothes are wet is solved. The control system is simple and reasonable in structure, belongs to a pure mechanical structure, meets use standards of a coal mine underground, and is long in service life and very suitable for being popularized and implemented.
Description
Technical field
The utility model relates to mine underground dustproof technical field, is specifically related to a kind of control system that can control respectively to both sides inside and outside water curtain on-off water.
Background technology
Mine coal seam solid coefficient is low, substantially powdered after coal blasting, further broken after transfer point in transportation, having produced a large amount of dust directly affects the production environment of mine, affect the healthy of miner, for mine safety production, carry out production strictly in line with rules and regulations and brought major hidden danger, cause the reason that mine dust concentration is higher to have 2 points: the one, the dust producing in Coal Transport, loading chute in mine air intake; The 2nd, the dust that digging place produces due to coal winning technologies such as blasting loadings.
Adopting at present more dust prevention is to adopt water curtain style dust prevention system, plays the effect of good isolation dust.But, there is defect in water supply line and the valve setting of current water curtain, workman enters opposite side after a side is closed feed pipe, also need again to open feed pipe, still need through water curtain, be that the every round trip of workman at least needs once to pass water curtain, water curtain can cause workman's clothes to be drenched, and brings inconvenience.
Have a kind of public technology of controlling water curtain water system on-off by infrared induction, this Technology Need arranges corresponding control module, and electromagnetic valve is set on supply channel, and the signal that receives infrared probe by control module is controlled electromagnetic valve work.Owing to adopting electronic equipment need to consider technological processing for explosion protection feature problem under coal mine, so not only cost is high for this scheme, and more difficult being applied under coal mine.Under coal mine, moist and dust atmosphere factor, causes electronic product generally shorter application life, once substantially be difficult to be equipped with in time after damaging, still brings inconvenience again.
Utility model content
The purpose of this utility model is to provide a kind ofly can control the double control-type water curtain control system that water route is switched on or switched off at water curtain either side.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: inside and outside double control-type water curtain control system under a kind of coal mine, comprise supply channel, valve and full section drenching installation, on described supply channel, be communicated with respectively left arm and right arm, the part that left arm is positioned at water curtain left side and right side is respectively provided with valve one and valve two, the part that right arm is positioned at water curtain left side and right side is respectively provided with valve three and valve four, described valve one and valve three are linkage valve, be valve a dozen convince by patient analysis and cause valve three and close, valve three is opened and is caused valve one to be closed, described valve two and valve four are linkage valve, be that valve two is opened and caused valve four to be closed, valve four is opened and is caused valve two to be closed.
Beneficial effect: the utility model adopts mechanical type control linkage valve, can guarantee the both sides at water curtain, can both control connection or the disconnection in water route, thus the permeable problem of clothes that causes while preventing workman by water curtain below, contacted with water curtain.The utility model is simple and reasonable, belongs to pure frame for movement, meets use standard under coal mine, and long service life is beneficial to promotion and implementation very much.
Brief description of the drawings
Fig. 1 is water route of the present utility model syndeton schematic diagram.
In figure, label 1 is water supply line, and 2 is left arm, and 3 is right arm, and 4 is Left-wing Federation's movable valve, and 5 is right linkage valve, and 6 is full section drenching installation.
Detailed description of the invention
Inside and outside double control-type water curtain control system under a kind of coal mine, referring to Fig. 1, supply channel 1 can be simultaneously for one or more water curtains provide water source.Water curtain forms and is provided by full section drenching installation 6.Near some water curtains, on supply channel 1, be communicated with respectively left arm 2 and right arm 3.Left arm 2 and right arm 3 are usually located at the left and right sides of water curtain.Left arm 2 and right arm 3 also can only be positioned at water curtain one side, but left arm 2 and right arm 3 all must some be positioned at left side and the right side of water curtain simultaneously.
The part that described left arm 2 is positioned at water curtain left side and right side is respectively provided with valve A and valve B, and the part that right arm 3 is positioned at water curtain left side and right side is respectively provided with valve C and valve D.Valve A and valve C are Left-wing Federation's movable valve 4, and valve A opens and causes valve C to close, and valve C opens and causes valve A to close.Valve B and valve D are linkage valve 5, and valve B opens and causes valve D to close, and valve D opens and causes valve B to close.
Known by Fig. 1 and above description, in the time that workman need to pass through water curtain from left to right, be on-state by front water curtain, if valve A opens, valve C closes, and the valve B on right side opens, and valve D closes.Now workman's manual-lock valve A, although valve C be opened, because the valve D on right side closes, so left arm 2 and right arm 3 are all in closed condition.After workman passes through, open again valve D on right side, now valve B closes, but the valve C in left side is open mode, so water curtain continues to be switched on.In the time that workman need to pass through water curtain from right to left, be on-state by front water curtain, if valve D opens, valve B closes, and the valve C on right side opens, and valve A closes.Now workman's manual-lock valve D, although valve B be opened, because the valve A on right side closes, so left arm 2 and right arm 3 are all in closed condition.After workman passes through, open again valve A in left side, now valve C closes, but the valve B on right side is open mode, so water curtain continues to be switched on.
