Abstract
The utility model provides a coalbed gas takes out and adopts recoverable quick hole sealing device, includes elastic rubber pipe, exhaust tube and gas tube. The both ends of elastic rubber pipe are passed through the closing plate and are sealed. The exhaust tube passes two closing plates and rubber tubes and extends to needs the gaseous position of extraction gas. The gas tube passes the closing plate that is located the outer end and inserts the rubber tube. The elastic rubber pipe can be at air pump air -blowing afterexpansion, and the after -contraction of bleeding makes things convenient for user of service to install the elastic rubber pipe and takes out in drilling or in holing, quick hole sealing device can also repetitious usage. Elastic rubber pipe comprises vulcanie pipeline section and soft rubber pipeline section, and yielding soft rubber pipeline section can play better sealed effect, and coefficient of friction is big between non -deformable's vulcanie pipeline section and the drilling inner wall, can prevent that the elastic rubber manages to follow to drop in driling.

Description
Technical field
The utility model relates to mine ventilation and safety field, is specifically related to a kind of recyclable rapid hole sealing device being applied to the efficient extraction of coal-bed gas, with the dual purpose reaching rapid hole sealing He reduce costs.
Background technology
In the sealing of hole of colliery, yellow mud or cement group sealing of hole are the method for sealing that China utilizes the earliest, the method use equipment is few, cost is low, but the labour intensity of workman is larger, waste time and energy, and yellow mud or clay are met water and are easily softened, and are usually suitable only for boring opening in the place of rock gangway, hole sealing depth is also shorter, and the extraction layer position of gas is easily restricted.By contrast, the hole sealing depth of injection hole sealing technology is relatively long, but because of cement mortar be dried to block after often there is many cracks, badly influence the quality of sealing of hole, so polyurethane material hole sealing technology arises at the historic moment.Facts have proved, the sealing of hole effect of polyurethane foam comparatively yellow mud or cement group's sealing of hole and injection hole sealing truly has change, but because its foamed time is short, quick solidifying, sometimes also do not reach desirable sealing of hole effect, cannot reclaim, cost is higher in addition, therefore is difficult to extensive employing.In addition, the application practice of PD material, Ma Lisan and resin anchoring agent has also been carried out in some places, sealing of hole effect is suitable with polyurethane material, research and development and the application of cushion rubber hole packer and capsule hole then make hole-sealing technology greatly improve, operate also comparatively easy, reusable several, but generally can only specially hole is special, not easily extensively promote.Therefore, research and develop a kind of easy to operate, with low cost, safety is high, the rapid hole sealing device of sealing of hole successful to raising the extraction level of gas and the comprehensive benefit in colliery there is very important directive significance.
Utility model content
Be merely able to be suitable for the problem of certain pore size to solve cushion rubber hole packer and capsule hole in prior art, the utility model provide a kind of easy to operate, with low cost, safety is high, the rapid hole sealing device that can be suitable for different pore size of sealing of hole successful.
The recyclable rapid hole sealing device of a kind of coal bed gas extraction, comprises elastic rubber pipe, exhaust tube and gas tube; The two ends of elastic rubber pipe are sealed by sealing plate.Exhaust tube through two sealing plates and rubber tube side by side and extend to the position needing gas extraction gas.Gas tube is through the sealing plate being positioned at outer end and insert rubber tube.
Preferably, described elastic rubber pipe comprises vulcanie pipeline section and soft rubber pipeline section, vulcanie pipeline section and soft rubber pipeline section spaced apart successively and be connected.Vulcanie pipeline section can prevent elastic rubber pipe from coming off in boring, and soft rubber pipeline section mainly plays sealing.
Preferably, elastic rubber pipe is made up of with the soft rubber pipeline section being positioned at middle part the vulcanie pipeline section being positioned at two ends.The vulcanie pipeline section at two ends mainly plays the effect preventing elastic rubber pipe from coming off in boring, and middle soft rubber pipeline section mainly plays the effect of sealing, and while above-mentioned design can play sealing and anticreep effect, structure is also simple, and cost is low.
Preferably, exhaust tube is connected with air exhauster, and exhaust tube is also provided with the first control valve.Gas tube is provided with air pump, gas tube is also provided with the second control valve.User of service can pass through air exhauster gas extraction, by air pump to elastic rubber pipe inflation or pressure release of bleeding.
Preferably, described sealing plate, exhaust tube and gas tube by glass fiber reinforced plastic or copper standby.Above-mentioned design, can avoid, because knock or collision etc. produces spark actuation gas, ensureing the safety in production of mine with this.
The utility model compared with prior art, has following beneficial effect:
The recyclable rapid hole sealing device of above-mentioned a kind of coal bed gas extraction, comprise elastic rubber pipe, elastic rubber pipe can expand after air-pump inflating, after-contraction of bleeding, elastic rubber pipe is arranged in boring or in boring and takes out by personnel easy to use, and described rapid hole sealing device can also repeatedly use.Elastic rubber pipe is made up of vulcanie pipeline section and soft rubber pipeline section, soft rubber pipeline section is easily out of shape, good sealing effectiveness can be played, the distortion of vulcanie pipeline section is little, but with friction factor is large between drill hole inner wall, good fixation can be played, prevent elastic rubber pipe from coming off in boring.In described elastic rubber pipe, aeration quantity is different, and the diameter after expansion is different, and by controlling aeration quantity, described receipts rapid hole sealing device can be suitable for the boring of different pore size.
