Description

Technical Field

[0001] This utility model belongs to the field of gas drainage technology, specifically relating to a gas drainage sealing device with a detection structure. Background Technology

[0002] Gas is a general term for gaseous fuels, whose main components are alkanes, with methane making up the vast majority, and small amounts of ethane, propane and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, as well as trace amounts of inert gases such as helium and argon.

[0003] Chinese Patent Application No. 202421035950.3 discloses a gas extraction and sealing device with a detection structure, comprising a main assembly. The main assembly includes a sleeve, with six sets of fixing rings fixedly connected to the inner wall of the sleeve. A suction pipe is fixedly connected to the inner wall of each of the six sets of fixing rings, and a sealing assembly is installed inside the suction pipe. This invention utilizes a rotating threaded sleeve to cause a circular shaft to drive a compression ring to compress the gas between the sleeve and the suction pipe. The gas is then diverted through an inlet connecting pipe into multiple sets of telescopic tubes. Under air pressure, the telescopic tubes extend from inside the sleeve, causing an air bladder and baffle to extend and adhere to the inner wall of the borehole. When the air bladder moves out of the sleeve, it expands, tightly adhering to the inner wall of the borehole, effectively improving the sealing effect and preventing gas leakage during extraction. The sealing assembly enables rapid sealing, further improving work efficiency.

[0004] 1. The aforementioned patent has the problem that the sealing device can easily slide up and down inside the borehole during the sealing process and cannot filter the gas, thus reducing the working capacity of the sealing device; 2. The aforementioned patent has the problem that when gas leaks in the borehole, it is inconvenient to transport the leaked gas to other locations, thus reducing the practicality of the sealing device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a gas extraction and sealing device with a detection structure, including an extraction pipe 1, an airbag assembly 2 installed at the lower position of the extraction pipe 1, a detection assembly 3 fixedly installed on one side of the extraction pipe 1 and above the airbag assembly 2, an exhaust pipe 5 provided above the extraction pipe 1, the extraction pipe 1 and the exhaust pipe 5 being connected by a fixed filter device 4, and a gas delivery device 6 fixedly installed on the outside of the extraction pipe 1 and above the detection assembly 3.

[0023] Specifically, the fixed filter device 4 includes a connecting box 41, a cone 43, a movable plate 44, and a bidirectional lead screw 46. The suction pipe 1 and the discharge pipe 5 are connected through the connecting box 41. The bidirectional lead screw 46 is mounted on the lower part of the connecting box 41 via a bearing. Two movable plates 44 are threadedly mounted on the outer side of the bidirectional lead screw 46, located inside the connecting box 41 and the suction pipe 1. Multiple cones 43 are fixedly mounted on the bottom of the two movable plates 44 on opposite sides. A filter assembly 42 is provided above the bidirectional lead screw 46.

[0024] By adopting the above technical solution, the workers can fix the position of the sealing device to a certain extent when needed by using the cooperation of the insert cone 43 and the two-way lead screw 46, thereby reducing the possibility of the sealing device sliding up and down in the borehole during the sealing process and better meeting the needs of the work.

[0025] Specifically, the fixed filter device 4 also includes a guide rod 45, which is fixedly installed on the inner side of the connecting box 41 and below the bidirectional lead screw 46.

[0026] By adopting the above technical solution, the sealing device can guide the movement of the moving plate 44 through the guide rod 45, thereby preventing the moving plate 44 from rotating or deviating during the movement and ensuring the normal operation of the work.

[0027] Specifically, the filter assembly 42 includes a filter screen 421, screws 422 and mounting plate 423. The mounting plate 423 is provided on one side of the connecting box 41 and above the bidirectional lead screw 46. The connecting box 41 and the mounting plate 423 are connected by screws 422. The filter screen 421 is fixedly installed on the side of the mounting plate 423 near the connecting box 41.

[0028] By adopting the above technical solution, the staff can filter the gas through the filter screen 421, thereby reducing the possibility of impurities in the gas entering the exhaust pipe 5 and better meeting the needs of the work.

[0029] In this embodiment, when a sealing device is needed during gas drainage, the worker inserts the sealing device into the borehole and rotates the bidirectional screw 46 in the fixed filter device 4. The bidirectional screw 46 is threadedly connected to the two moving plates 44, and the two moving plates 44 are slidably connected to the guide rod 45. Therefore, the bidirectional screw 46 drives the two moving plates 44 to move, thereby driving each insert cone 43 to penetrate into the inner wall of the borehole, thus fixing the position of the sealing device. Then, the borehole is sealed by the airbag assembly 2. The discharge pipe 5 is connected to the external gas extraction equipment, and then the gas is extracted. The gas enters the extraction pipe 1 and is detected by the detection assembly 3. Then, the gas enters the connecting box 41 and is filtered by the filter screen 421 in the filter assembly 42. Then, the gas is discharged through the discharge pipe 5 for use. The screw 422 serves to connect the mounting plate 423 and the connecting box 41. The battery 63 is electrically connected to each blower 64.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the gas delivery device 6 includes a gas delivery hose 61, an annular box 62, a battery 63, and a fan 64. The annular box 62 is fixedly installed on the outside of the suction pipe 1 and above the detection component 3. Multiple fans 64 are fixedly installed below the annular box 62 and above the detection component 3. The battery 63 is fixedly installed on one side of the annular box 62, and the gas delivery hose 61 is fixedly installed on the side of the annular box 62 away from the battery 63.

[0032] By adopting the above technical solution, workers can use the combination of the blower 64 and the gas delivery hose 61 to transport the leaked gas to other locations when a gas leak occurs in the borehole, thereby reducing the possibility of an accident.

[0033] Specifically, the gas conveying device 6 also includes a partition net 65, which is fixedly installed below the air inlet end of the fan 64.

[0034] By adopting the above technical solution, the sealing device can prevent external impurities from entering the inside of the fan 64 through the partition 65, thereby reducing the possibility of adverse effects on the fan 64 and other structures, and thus ensuring the normal operation of the work.

[0035] In this embodiment, when a gas leak occurs in the borehole, the operator starts each of the blowers 64 in the gas delivery device 6. Each blower 64 sends the leaked gas, which has been filtered by the mesh 65, into the annular box 62. Then the gas passes through the gas delivery hose 61 and is sent to other locations, thereby reducing the possibility of an accident.

[0036] The structure and principle of the extraction pipe 1, the airbag assembly 2 (comprising a sleeve, a fixing ring, a compression ring, a round shaft, a threaded sleeve, a connecting pipe, a telescopic pipe, a baffle, and an airbag), and the detection assembly 3 in this utility model have been disclosed in a gas extraction and sealing device with a detection structure disclosed in Chinese patent application number 202421035950.3. Its working principle is as follows: during use, the sleeve is inserted into the borehole, and then the rotating threaded sleeve drives the round shaft to rotate. The round shaft drives the compression ring to compress the gas between the sleeve and the extraction pipe, allowing the gas to enter the connecting pipe. The gas then flows from the connecting pipe into multiple sets of telescopic pipes, causing the telescopic pipes to extend from the sleeve under air pressure, driving the airbag and baffle to extend and adhere to the inner wall of the borehole. When the airbag exits from the sleeve... When the cylinder is removed from the borehole, it expands and fits tightly against the borehole wall, effectively improving the sealing effect and preventing gas leakage during gas extraction. The sealing component enables rapid sealing, further improving work efficiency. Gas is extracted through the extraction pipe. When it is necessary to detect the gas inside the ore layer, the piston rod is pulled to raise the piston, which compresses the spring and extracts gas from the extraction pipe through the vertical pipe. The gas then enters the detector through the detection pipe to monitor the gas concentration inside the ore layer in real time, effectively ensuring the safety of workers in subsequent work and preventing accidents. Parts not involved in this device are the same as or can be implemented using existing technologies.

[0037] The working principle and usage process of this utility model are as follows: When a sealing device is needed during gas drainage, the worker inserts the sealing device into the borehole and rotates the bidirectional screw 46 in the fixed filter device 4. The bidirectional screw 46 is threadedly connected to the two moving plates 44, and the two moving plates 44 are slidably connected to the guide rod 45. Therefore, the bidirectional screw 46 drives the two moving plates 44 to move, thereby driving each insert cone 43 to penetrate into the inner wall of the borehole, thus fixing the position of the sealing device. Then, the borehole is sealed by the airbag assembly 2. The discharge pipe 5 is connected to the external gas extraction equipment, and then the gas is extracted. The gas enters the extraction system. The gas enters the connecting box 41 and is filtered by the filter screen 421 in the filter assembly 42. The gas is then discharged through the discharge pipe 5 for use. The screw 422 connects the mounting plate 423 and the connecting box 41. The battery 63 is electrically connected to each blower 64. When a gas leak occurs in the borehole, the operator starts each blower 64 in the gas delivery device 6. Each blower 64 sends the leaked gas, filtered by the screen 65, into the annular box 62. The gas then passes through the gas delivery hose 61 and is sent to other locations, thereby reducing the possibility of an accident.
