Description

Inflatable ventilation structure sealing device

Technical Field

The utility model relates to an inflatable ventilation structures obturator.

Background

The aim of mine ventilation is to create a good production operation environment, implement feasible prevention and treatment measures for dust and fire, improve the disaster resistance and relief capability of the mine and remove toxic and harmful gases. In order to ensure that the air volume of each roadway under the mine is enough or certain ventilation requirements are met, the ventilation structure is adopted for auxiliary realization. And the current ventilation structure has heavy size, complex installation and disassembly and untight closure to the roadway, thereby threatening the production safety under the field. The ventilation system of the general large and medium mine is a nonlinear fluid network composed of hundreds of air ducts, even thousands of air ducts, and the wind resistance and natural wind pressure of many air ducts are changed at any time along with the changes of ground atmospheric pressure and ground temperature, the deformation of a roadway, the propulsion of a driving working face and a recovery working face, the state change of ventilation facilities and the disturbance of various vehicles and equipment.

Many experts and scholars at home and abroad have devoted themselves to the research on mine ventilation theory, technology and application for many years, but no substantial breakthrough has been made in the aspects of mine ventilation state identification and automatic regulation. So far, the ventilation system of the mine still stays at the manual or semi-manual stage, so that the large-scale mine, especially the large-scale coal mine is difficult to realize effective ventilation and air supply according to the requirement, not only serious waste of manpower, material resources and financial resources is caused, but also 'one ventilation, three prevention' accidents and gas accidents happen occasionally, and after the disaster happens, the wind flow cannot be effectively controlled in real time to meet the requirements of pressure-equalizing fire extinguishing, disaster control, disaster resistance and disaster relief, and huge casualties and economic losses are caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses improve above-mentioned problem, promptly the to-be-solved technical problem of the utility model is to provide an inflatable ventilation structures obturator.

The utility model discloses a constitute like this, it includes the rubber gasbag that is used for aerifing shutoff ventilation structure, in the bottom embedding underground ventilation structure's of rubber gasbag protected draw-in groove, the rubber gasbag outside is provided with rimq device.

Further, the rubber air bag comprises an inflatable rubber ring, and the outer ring of the inflatable rubber ring is connected with the rock wall in a propping mode.

Furthermore, the inflatable rubber ring is driven by an inflation and deflation device to inflate and deflate.

Furthermore, the windless side of the rubber air bag is provided with a plurality of buckles for being fixedly connected with a plurality of support rods to strengthen the stability.

Furthermore, the wind shielding device is a wind-proof plastic bag wrapping the integral rubber air bag, and the wind-proof plastic bag is positioned between the rubber air bag and the ventilation structure channel.

Further, the wind shielding device can also be alkali-free glass fiber cloth used for sealing the inner ring in the middle of the rubber air bag.

Further, an inflatable inner tube is arranged inside the inflatable rubber ring.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model relates to a rationally, simple structure when satisfying diversified tunnel ventilation demand, can carry out the interim shutoff of distinguished and return air tunnel of distinguished and admirable high-efficiently, has realized the dynamic adjustment of underground mine ventilation system amount of wind, has alleviateed the weight of ventilation structures simultaneously and the installation, the work load when dismantling, has solved the needs of the shorter age that needs sometimes, convenient maintenance and change.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example (b): as shown in fig. 1 to 3, an inflatable ventilation structure sealing device is provided, which comprises a rubber air bag for inflating and sealing a ventilation structure, wherein the bottom of the rubber air bag 2 is embedded into a protective clamping groove 3 of an underground ventilation structure to prevent the rubber air bag from being damaged by sharp rock masses below and on the left and right sides, and a wind shielding device is arranged outside the rubber air bag.

The protective clamping groove needs to be dug at the road junction for auxiliary fixation, so that the strength of a ventilation structure is increased.

In this embodiment, the rubber airbag includes an inflatable rubber ring, and an outer ring of the inflatable rubber ring abuts against the rock wall.

In this embodiment, the inflatable rubber ring is driven by the inflation and deflation device to inflate and deflate.

In the embodiment, a plurality of buckles 1 are arranged on the windless side of the rubber air bag and are fixedly connected with a plurality of support rods to further enhance the overall stability; the middle part of the buckle is provided with a clamping hole.

In this embodiment, the wind shielding device may be a wind-proof plastic bag that covers the integral rubber airbag, and the wind-proof plastic bag is located between the rubber airbag and the ventilation structure channel and completely covers all the rubber airbags inside;

the windshield device can also be alkali-free glass fiber cloth used for sealing the inner ring in the middle of the inflatable rubber ring, and the alkali-free glass fiber cloth can be adhered to the inner ring of the inflatable rubber ring through a magic tape.

In this embodiment, the interior of the inflatable rubber ring may have an inflatable inner tube.

Any technical solution disclosed in the present invention is, unless otherwise stated, disclosed a numerical range if it is disclosed, and the disclosed numerical range is a preferred numerical range, and any person skilled in the art should understand that: the preferred ranges are merely those values which are obvious or representative of the technical effect which can be achieved.
