Abstract
The utility model relates to an automatic water drainage device for gas drainage of a coal mine, which comprises a connecting pipeline and a water drainage pipeline arranged below the connecting pipeline, wherein a floating ball positioning pipe is connected below the connecting pipeline and is connected with the water drainage pipeline, a limiting stop lever is arranged at the middle part of the water drainage pipeline and a floating ball is arranged above the limiting stop lever. The device can be mounted and used in a ponding tank arranged in a low-lying place of a drainage system and can also be mounted and used in a temporary ponding point, and patrol inspection and maintenance staff are not required during the operation of the device; as a complex mechanical structure is not used, the automatic water drainage device is very less prone to blockage; processing material is low in manufacturing cost, and the processing is easy and can be performed by an ordinary lathe operator; and the automatic water drainage device does not need the special process and equipment.
Description
Technical field
The utility model relates to a kind of mining safety device, is specifically related to a kind of dewatering installation that uses in gas discharge in mine, the automatic jettison gear of particularly a kind of gas discharge in mine.
Background technology
Gas drainage under suction is the measure of adopting special equipment that the combustible gas in coal seam, rock stratum and the goaf is extracted out or discharged.Gas emission is very big in the coal mine, and when being difficult to the dilution eliminating by ventilation, the method for available extraction is got rid of gas, reduces the burden of ventilating.At the end of the forties, the Chinese test that draws out methane in the coalfield, Fushun is applied to produce the fifties, and extracted quantity increases year by year.Thereafter the work of drawing out methane is also carried out in mining areas such as Yangquan, the self-sufficient and strategically located region, middle Liangshan, packet header, Nan Tong, Beipiao City successively.More than 100 mine in the whole nation in 1981 installed the equipment that draws out methane, and drawing out methane every year reaches 300,000,000 meter 3, supplies with industry, domestic fuel and makes industrial chemicals, turns bane into boon.Set up the gas pumping plant on ground, the pipe-line system that draws out methane through the down-hole is connected with extraction boring, causes negative pressure during the pump running, and gas is extracted out, sends into the gas jar, or directly supplies with the user.As it is less to extract gas quantity out, or very unstable, can directly be discharged in the atmosphere.
At present, gas discharge in mine is one of main means of administering the gas disaster, but owing to accumulate ponding through regular meeting in the restriction of extraction condition, extraction system pipeline, ponding not only influences the extraction effect and also causes hidden danger.Old-fashioned jettison gear is stopped up by foreign material through regular meeting owing to reasons such as complex structures, loses the function that discharges water automatically.
Summary of the invention
At the deficiencies in the prior art, the utility model provide a kind of simple in structure, automaticity is high, the automatic jettison gear of gas discharge in mine with low cost, that gas drainage under suction is effective.
The technical solution of the utility model is achieved in that the automatic jettison gear of a kind of gas discharge in mine, the drainage pipe that comprises connecting pipe and be arranged on the connecting pipe below, described connecting pipe below is connected with the ball float positioning pipe, the ball float positioning pipe is connected with drainage pipe, be provided with spacing pin at the drainage pipe middle part, spacing pin top is provided with ball float.
The lower end of described ball float positioning pipe is the sphere opening, the internal diameter of this sphere opening and the equal diameters of ball float.
Described connecting pipe outer setting has the connecting pipe sleeve pipe, and the connecting pipe sleeve pipe is threaded with connecting pipe and ball float positioning pipe.
Described drainage pipe outer setting has the drainage pipe sleeve pipe, and the drainage pipe sleeve pipe is threaded with drainage pipe.
Described ball float positioning pipe adopts pvc pipe material or nylon pipe.
Described drainage pipe sleeve pipe is provided with the locking positioning bolt.
The utlity model has following good effect: the utility model can make the ponding that accumulates in the gas discharge in mine system pipeline in time discharge, and does not influence the normal extraction of system simultaneously, does not need repairing usually.Be applied to reduce working strength of workers greatly in the gas discharge in mine system, reduce maintenance cost, improve the gas drainage under suction effect, promote Safety of Coal Mine Production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the automatic jettison gear of a kind of gas discharge in mine, the drainage pipe 5 that comprises connecting pipe 1 and be arranged on connecting pipe 1 below, described connecting pipe 1 below is connected with ball float positioning pipe 2, ball float positioning pipe 2 is connected with drainage pipe 5, be provided with spacing pin 4 at drainage pipe 5 middle parts, spacing pin 4 tops are provided with ball float 3.
The lower end of described ball float positioning pipe 2 is the sphere opening, the equal diameters of the internal diameter of this sphere opening and ball float 3.Described connecting pipe 1 outer setting has connecting pipe sleeve pipe 8, and connecting pipe sleeve pipe 8 is threaded with connecting pipe 1 and ball float positioning pipe 2.Described drainage pipe 5 outer setting have drainage pipe sleeve pipe 7, and drainage pipe sleeve pipe 7 is threaded with drainage pipe 5.Described ball float positioning pipe 2 adopts pvc pipe material or nylon pipe.Described drainage pipe sleeve pipe 7 is provided with locking positioning bolt 6.
The utility model is at outer end, ball float positioning pipe 2 two car screw thread, and an end links to each other with drainage pipe 5.The other end is connected with connecting pipe 1.The water tank that is provided with in connecting pipe 1 and the extraction pipeline system links to each other, be provided with spacing pin 4 at drainage pipe 5 middle parts and prevent the ball float whereabouts of transfiniting, regulate the distance up and down of drainage pipe 5 and ball float positioning pipe 2 then according to vacuum magnitude, it is the stroke up and down of ball float 3, so that ball float 3 is beated freely, adjust suitable back and get final product with 6 lockings of locking positioning bolt.
This product is vertically installed up and down, and light is good more more for ball float 3 and ball positioning pipe 2 processing fineness.Ball float 3 wants consistent with the radian of ball positioning pipe 2 processing, so that reach best sealing effectiveness.Ball float 3 selects for use general table tennis to get final product.
This product processing dimension can be according to the extraction system size, water yield size, and vacuum magnitude, processing dimension is amplified arbitrarily or is dwindled.The length of connecting pipe 1 that can extend when discharging water effect as vacuum magnitude influence is so that reach the best effect that discharges water.
The water tank that this product can be provided with at the low-lying place of extraction system is installed and used, and also can install and use at the casual water point, and being in operation does not need to patrol and examine the attendant, owing to do not have complex mechanical construction, the utmost point to be not easy to stop up.The rapidoprint cost is low, processing easily, and general turner can be processed.Do not need special process and equipment.
