Detailed Description
The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the present invention, but are not intended to limit the scope of the present invention.
Example (b):
please refer to fig. 1 to fig. 3; the utility model provides an air pipe for colliery is taken a breath, include: the device comprises a device body 1, reinforcing rings 2 and a protective ring 3, wherein the inner wall of the device body 1 is fixedly provided with the three reinforcing rings 2, the inner wall of each reinforcing ring 2 is welded with a supporting beam 201, the bottom end of the inner wall of each reinforcing ring 2 is provided with a small pipeline 202, supporting rods 4 are welded between the left side and the right side of each reinforcing ring 2, and the protective ring 3 is embedded in the outer surface of the device body 1;
the support rod 4 includes: the telescopic rod 401, the rotating ball 402 and the auxiliary support rod 403 are arranged on the right side of the support rod 4 in a nested mode, the rotating ball 402 is welded on the right side of the telescopic rod 401, and the auxiliary support rod 403 is arranged on the right side of the rotating ball 402 in a nested mode.
Wherein, the guard ring 3 is provided with threely, and the guard ring 3 is arranged for horizontal equidistance and sets up the surface at device main part 1, and because of the use of taking a breath for the colliery of device main part, the ore on ground and the friction of device main part 1 cause the damage to device main part 1 easily, and guard ring 3 can reduce and prop area and the distance of device main part 1 and ground contact for the life of device main part 1 is longer.
The inner wall of the device main body 1 is provided with the anti-static rubber strip, when the device main body 1 ventilates a coal mine, the gas in the air and the inner wall of the device main body 1 can generate static electricity, the static electricity can cause sparks to detonate the gas in the device main body 1, and the inestimable result is caused, and the anti-static rubber strip arranged on the inner wall of the device main body 1 can reduce the static electricity generated by the friction between the air flowing in the device main body 1 and the inner wall of the device main body 1.
Wherein, a supporting beam 201 is "X" word form, and supporting beam 201's surface nestification is provided with anti-static cloth, because of device main part 1 is as for carrying oxygen in the pit, supporting beam 201 can support the reinforcement ring 2 and consolidate all around, make device main part 1's whole bear the pressure value and improve, make device main part 1 when being pressed to by a small amount of ore, be difficult to block up device main part 1 and ventilate the pit, and supporting beam 201 surface nestification sets up anti-static cloth can effectively stop device main part 1 when ventilating the pit air, because of the pit contains gas in the air, and gas can not produce static and arouse the gas in the spark ignition device main part 1 with supporting beam 201 frictional contact.
The small pipelines 202 are four 'annular' shaped and equidistantly arranged on the inner wall of the device main body 1, when the device main body 1 discharges air under a mine, the air and oxygen are conveyed under the mine due to the fact that the air under the mine is lack of air and uninterrupted air backflow is achieved, when the device main body 1 ventilates the mine, the air and oxygen needing backflow can be sucked into the mine through the small pipelines 202, effective ventilation and ventilation are achieved for underground operation personnel, and the air and oxygen can be continuously conveyed under the mine while ventilation and ventilation are achieved for the mine.
