Abstract
The utility model relates to a hole-sealing connecting rod for a CO2 gas exploitation device. The hole-sealing connecting rod for the CO2 gas exploitation device includes a connecting pipe and a connector, wherein pin holes are formed at the two ends of the connecting pipe and the connector, pins penetrate the pin holes to connect the connecting pipe and the connector, and the connector can be used for being connected with a hole-sealing device. Through the hole-sealing connecting rod, the hole-sealing device for the CO2 gas exploitation device can be conveniently extended and connected to the outside of a pre-split hole for operation; and the structure is simple and practical.
Description
Technical field
The utility model relates to a kind of connecting rod, is used to connect CO when being specifically related to a kind of coal-bed gas extraction
2The sealing of hole connecting rod of gas-field exploitation device hole sealing device.
Background technology
Use CO
2Gas-field exploitation device presplitting high gas layer improves gas pumping efficient, is to solve a difficult innovative technology of present coal mine gas extraction.Early stage, effect test proved, through CO
2The coal seam of gas-field exploitation device presplitting and not presplitting coal-bed gas extraction effect comparison; Not only can make the extraction flow improve 1.9-3.7 doubly; Main is that gas pumping concentration can improve 5-20 times more than; Under the situation of simplifying the extraction system greatly, solved an extraction difficult problem, made gas pumping become easily, simplify, thoroughly.Therefore, use CO
2Gas-field exploitation device presplitting high gas layer is a key technology that realizes gas control, not only can effectively realize gas control, also can become the technical guarantee that gas resources makes full use of.
Utilize CO
2The gas-field exploitation device carries out presplitting to gassy seam also need dispose necessary corollary equipment.During presplitting, not only need be a plurality of CO
2Inserted in the presplitting hole in coal seam since the gas-field exploitation device connects, also need carry out effective seal the presplitting hole.With the hole sealing device certain degree of depth in the presplitting hole of packing into, just possibly reach the better seal effect, be connected on the hole sealing device and at this moment just need an ejector, continuity causes outside the presplitting hole to be handled hole sealing device.
Summary of the invention
The purpose of the utility model provides a kind of CO of being used for
2The sealing of hole connecting rod of gas-field exploitation device, with outside the presplitting hole to CO
2Gas-field exploitation device hole sealing device is handled.
The sealing of hole connecting rod of the utility model is made up of tube connector and connector; Two ends at tube connector and connector are equipped with pin-and-hole; Connector is enclosed within the tube connector, and is hinged through the pin that penetrates in the pin-and-hole, and said connector can be used for connecting hole sealing device or other devices.
The use that can a plurality ofly be together in series of above-mentioned sealing of hole connecting rod.
The pin-and-hole that is positioned at the tube connector two ends is vertically disposed each other, and sealing of hole connecting rod that can guarantee to link together and hole sealing device or other devices can multi-faceted adjustment freely, to adapt to the duct shape in presplitting hole.
Because of presplitting needs, hole sealing device must be installed in certain depth place in the presplitting hole, possibly need a plurality of sealing of hole connecting rod assemblings could realize operating function.During use; The connector of sealing of hole connecting rod at first is connected with hole sealing device; Hole sealing device and the presplitting device that assembles are pushed in the presplitting hole, and other sealing of hole connecting rods of continued access push step by step inwards; Make hole sealing device to design attitude, the inner rotary sealing of hole connecting rod in the presplitting hole is so that hole sealing device sealing and after presplitting, remove the sealing of hole sealing device.
The sealing of hole connecting rod of the utility model is simple in structure, practical, can be easily with CO
2The continuity of gas-field exploitation device hole sealing device connects and causes outside the presplitting hole, outside the presplitting hole, to handle hole sealing device.
Description of drawings
Fig. 1 is that the utility model is used for CO
2The structural representation of the sealing of hole connecting rod of gas-field exploitation device.
Among the figure: 1. tube connector, 2. connector, 3. pin-and-hole, 4. pin.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Be used for CO
2Sealing of hole connecting rod structure such as Fig. 1 of gas-field exploitation device are made up of tube connector 1 and connector 2, and the two ends of tube connector 1 are provided with orthogonal pin-and-hole 3, and the two ends of connector 2 also are provided with pin-and-hole 3, and tube connector 1 penetrates in the pin-and-hole 3 through pin 4 with connector 2 and flexibly connects.Connector 2 can be connected with hole sealing device, another sealing of hole connecting rod or other devices.
Claims (2)
1. one kind is used for CO
2The sealing of hole connecting rod of gas-field exploitation device is characterized in that being made up of tube connector and connector, is equipped with pin-and-hole at the two ends of tube connector and connector, and connector is enclosed within the tube connector, and is hinged through the pin that penetrates in the pin-and-hole.
2. sealing of hole connecting rod according to claim 1 is characterized in that being positioned at the vertical each other setting of pin-and-hole at tube connector two ends.
