[0016] The preferred technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0017] Example 1

[0018] A device for preventing abnormal leakage for drilling construction, such as Figure 1-2 As shown, it includes a support leg 1, an air-water separator 2, a suction port 3, a first flange 4, a connecting pipe 5, a second flange 6, a slag discharge port 7, a plug 8, a slag discharge pipe 9 and an exhaust pipe 10. The lower part of the air-water separator 2 is connected to three support legs 1, and the lower sides of the support legs 1 are provided with anti-slip pads to prevent movement. The upper left side of the air-water separator 2 is connected to the suction port 3, the lower side of the air-water separator 2 is connected to the first flange 4, the upper right side of the air-water separator 2 is connected to the exhaust pipe 10, the tail end of the exhaust pipe 10 is connected to the connecting pipe 5, the left side of the connecting pipe 5 is connected to the second flange 6, the diameter of the first flange 4 is smaller than that of the second flange 6, and the middle part of the second flange 6 is provided with a jack for easy insertion and knocking. The lower side of the connecting pipe 5 is connected to the slag discharge port 7, and the plug 8 is connected to the right side of the connecting pipe 5. The upper right side of the air-water separator 2 is connected to the slag discharge pipe 9, and the tail end of the slag discharge pipe 9 is connected to the slag discharge port 7.

[0019] When drilling construction needs to prevent abnormal leakage, this device can be used. The device is brought to the place where drilling construction is required, so that the anti-slip mat contacts the ground, and then the device is placed on the ground. Then the insertion tube 8 is inserted into the specified position of the drilling hole, so that the connecting pipe 5 contacts the specified position of the drilling hole, and then the position of the gas-water separator 2 is moved so that the slag discharge pipe 9 is in an inclined state. Then the drill rod can be inserted from the socket on the second flange 6, and then the extraction port 3 is connected to the extraction system. Then the drill rod can be used to knock the coal mine, and at the same time, by starting the extraction system, toxic and harmful gases such as gas are sucked into the exhaust pipe 10 through negative pressure. The gas-water separator 2 is then extracted from the extraction port 3, thereby preventing the abnormal outflow of toxic and harmful gases such as gas. The operation is simple and easy to use, reducing the risk of operators inhaling toxic and harmful gases, ensuring the safety of operators, and reducing purchase costs. The debris and water generated when the drill rod hits the coal mine fall into the slag discharge pipe 9 from the slag discharge port 7, enter the gas-water separator 2, and are discharged from the first flange 4. The diameter of the first flange 4 is smaller than that of the second flange 6. After the drilling is completed, the extraction system is turned off, and then the drill rod is removed, and then the connecting pipe 5 is disconnected from the specified position of the drill hole, and then the insert 8 can be pulled out.

[0020] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
