Description

Technical Field

[0001] This utility model relates to the field of gas extraction technology, specifically a high-level borehole extraction device. Background Technology

[0002] The high-level gas drainage drilling site in the return air roadway is 5 meters wide, 4.5 meters deep, and 3 meters high. The site includes ten high-level gas boreholes arranged in a double row, constructed according to the design. Boreholes along the coal seam are also constructed. The following problems arise during actual operation: 1. The drilling site has limited space, and drainage accessories such as the slag discharge box, drainage box, water discharge device, and drainage pipelines are placed separately, making installation and removal complex. This results in high space occupancy, hindering overall management and potentially affecting drainage efficiency. 2. The manual water discharge device system has poor stability, requires significant manpower, and has a high probability of valve misoperation. Repeated valve rotation, due to uneven manual movements, often leads to valves not closing tightly, affecting the normal operation of the drainage system. 3. As the coal face advances, single-pillar supports need to be installed within the drilling site to support the roof. These supports affect the connection between the drainage device and the high-level boreholes, making gas leaks at pipeline connections more likely and impacting drainage efficiency. It is also not conducive to the detection and monitoring of drilling parameters.

[0003] Therefore, we propose a high-level borehole extraction device to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] like Figures 1-3As shown in the figure, an embodiment of the present invention discloses a high-level borehole extraction device, including an extraction main pipe 1. An extraction mechanism 2 is fixedly installed on the left side of the extraction main pipe 1. Branch pipes 3 are evenly fixedly installed from left to right on the upper surface of the extraction main pipe 1. A first butterfly valve 4 is fixedly installed on the upper surface of each branch pipe 3. A detection mechanism 5 is installed on the upper surface of the first butterfly valve 4. An air intake mechanism 6 is fixedly installed on the upper surface of the detection mechanism 5. Support mechanisms 7 are fixedly installed on the lower surface of the extraction main pipe 1 near the left side. Furthermore, an automatic water drainer 8 is fixedly installed on the upper side of the left support mechanism 7. An inlet pipe 9 is fixedly installed on the upper surface of the automatic water drainer 8, and the inlet pipe 9 is connected to the lower surface of the extraction body through a connecting mechanism 10. A drain pipe 11 is fixedly installed at the lower edge of the right side wall of the automatic water drainer 8. A controller 12 is provided on the front side of the extraction main pipe 1. The controller 12 is used to control the opening and closing of various electrical components and to process the data collected by the detection mechanism 5. The controller 12 is installed at a suitable position on the extraction main pipe 1.

[0024] like Figure 1 As shown, in some embodiments, the extraction mechanism 2 includes a second butterfly valve 201 and a connecting pipe 202. The second butterfly valve 201 is fixedly installed on the left side of the extraction main pipe 1. The connecting pipe 202 is installed on the left side of the second butterfly valve 201 and is connected to the extraction pump. When the second butterfly valve 201 is opened, the extraction pump extracts air from the extraction main pipe 1 through the connecting pipe 202.

[0025] like Figure 1 As shown, in some embodiments, the detection mechanism 5 includes a circular tube 501, a gas concentration sensor 502, and a flow sensor 503. The circular tube 501 is fixedly installed on the upper surface of the branch pipe 3. The gas concentration sensor 502 and the flow sensor 503 are installed on the side wall of the circular tube 501. The gas concentration sensor 502 and the flow sensor 503 can collect the concentration and flow rate of the gas entering the circular tube 501.

[0026] like Figure 1 As shown, in some embodiments, the air intake mechanism 6 includes a Y-type filter 601, a metal hose 602, and a mesh cylinder 603. The Y-type filter 601 is installed on the upper surface of the circular pipe 501. The metal hose 602 is fixedly installed on the upper surface of the Y-type filter 601. The mesh cylinder 603 is fixedly installed on the upper end of the metal hose 602. The mesh cylinder 603 on the metal hose 602 is inserted into the high-level borehole. The mesh cylinder 603 allows the gas in the high-level borehole to flow into the metal hose 602 and filters out larger particles. Then, the smaller particles are filtered out by the Y-type filter 601, so that the gas is drawn into the extraction main pipe 1.

[0027] like Figure 1As shown, in some embodiments, the cross-section of the mesh cylinder 603 is a tapered structure, which allows the mesh cylinder 603 to be better inserted into the high-level borehole.

[0028] like Figure 2 As shown, in some embodiments, the support mechanism 7 includes a support frame 701 and braked rollers 702. The support frame 701 is fixedly installed on the lower surface of the extraction main pipe 1. Braked rollers 702 are fixedly installed on the lower surface of the support frame 701 near the front and rear positions. The left and right support frames 701 are used to support the extraction main pipe 1, and the front and rear braked rollers 702 on the lower surface of the left and right support frames 701 facilitate the movement of the extraction device.

[0029] like Figure 2 As shown, in some embodiments, the connecting mechanism 10 includes a water outlet connector 101 and a conduit 102. The lower surface of the extraction main pipe 1 is fixedly installed with water outlet connectors 101 near the left and right positions. The water outlet connectors 101 are all connected to the water inlet pipe 9 through the conduit 102. The water outlet connectors 101 allow water in the extraction main pipe 1 to flow into the automatic water drainer 8 through the conduit 102. When the water in the automatic water drainer 8 reaches a certain height, the water in the automatic water drainer 8 is discharged through the drain pipe 11.

[0030] In use, the left and right support frames 701 in the support mechanism 7 support the main extraction pipe 1, and the front and rear brake rollers 702 on the lower surface of the left and right support frames 701 facilitate the movement of the extraction device. After moving the extraction device to the desired location, the mesh tube 603 on the metal hose 602 in the air intake mechanism 6 is inserted into the high-level borehole. The controller 12 then opens the first butterfly valve 4 and the second butterfly valve 201 in the extraction mechanism 2, connecting the connecting pipe 202 to the extraction pump. The extraction pump then draws air from the main extraction pipe 1 through the connecting pipe 202. The main extraction pipe 1 draws air from the Y-type filter 601 through the branch pipe 3 and the detection mechanism 5. The mesh tube 603 allows air to pass through the high-level borehole. Gas flows into the metal hose 602, where larger particles are filtered, and then smaller particles are filtered through the Y-type filter 601. This allows the gas from the high-level borehole to flow into the extraction main pipe 1. The water flowing into the extraction main pipe 1 flows into the conduit 102 through the water outlet connector 101 in the connecting mechanism 10, and then into the automatic water drainer 8 through the conduit 102. When the water level reaches a certain height, the water in the automatic water drainer 8 is discharged through the drain pipe 11. This allows for the interconnection and extraction of high-level boreholes at different angles. This multi-functional high-level borehole extraction device integrates gas collection and extraction, water discharge, slag removal, and parameter measurement. It also allows the extraction device to be moved to the next drilling site for extraction, making it convenient to use.

[0031] In summary, this high-level borehole extraction device is a multi-functional device that can connect and extract high-level boreholes at different angles, and integrate gas collection, water release, slag removal, and parameter measurement. Furthermore, the extraction device can be moved to the next drilling site for extraction, making it convenient to use.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
