[0002] During coal mining, the release and accumulation of gas is one of the major safety hazards. In order to effectively prevent and control gas disasters, gas adsorption devices are widely used in coal mines to adsorb and reduce the gas concentration in the air, and separate the gas from the airflow through the principle of physical adsorption. However, this device faces some problems in actual use.

When it is necessary to replace the adsorbent or clean the adsorption plate, the operator must use additional tools to operate, which not only increases labor intensity, but also affects production efficiency, while affecting the work efficiency of the operator, thereby reducing the overall use effect of the gas adsorption device.

[0004] Therefore, a gas adsorption device for underground gas prevention and control is needed to solve the problem that the adsorption plate of the existing gas adsorption device is inconvenient to disassemble and assemble, thereby affecting the maintenance efficiency of the operator.

[0029] Example

[0030] Reference Figures 1 to 10 A gas adsorption device for underground gas prevention and control includes an adsorption device body 1, a movable frame 2, and an adsorption plate 3. The interior of the adsorption device body 1 is a cavity. A plurality of first plug interfaces 7 are spaced apart on the front panel of the adsorption device body 1. A movable frame 2 is provided in each first plug interface 7. The movable frame 2 is inserted into and pulled out of the first plug interface 7. A mounting plate 8 is provided at the bottom of each movable frame 2. A plurality of mounting grooves 5 matching the mounting plate 8 are provided on the inner bottom surface of the adsorption device body 1. The movable frame 2 is slidably connected to the mounting groove 5 through the mounting plate 8 and is thus inserted into the adsorption device body 1.

[0031] The movable frame 2 is a rectangular frame, and a second plug-in port 201 is provided on the upper surface of the movable frame 2. The adsorption plate 3 is inserted into and pulled out of the second plug-in port 201. Moving grooves 14 are symmetrically provided on the front and rear sides of the movable frame 2 along the vertical direction. The front and rear sides of each adsorption plate 3 are provided with plug-in blocks 4 protruding outward. The adsorption plate 3 is slidably connected to the moving groove 14 through the two plug-in blocks 4 and is thus inserted into the movable frame 2.

[0032] Reference Figure 6, two slide grooves 11 are symmetrically provided on the front end surface of the moving frame 2, and a connecting groove 202 is provided on the outside of each slide groove 11. A pull block 10 is installed in each slide groove 11. The pull block 10 is a T-shaped block, including an integral sliding plate 101 and a handle 102. The sliding plate 101 is placed in the slide groove 11 on one side close to the connecting groove 202. The handle 102 passes through the slide groove 11 and is placed on the outside of the front end surface of the moving frame 2, and fits between the moving frame 2. One side of the sliding plate 101 is fixed to the limiting plate 9, and the limiting plate 9 is slidably placed in the connecting groove 202. The other side of the sliding plate 101 is fixed to one end of the elastic member 12, and the elastic member 12 is placed in the slide groove 11, and the other end of the elastic member 12 is fixed to the inner wall of the slide groove 11; limiting grooves 6 are provided on the left and right sides of each first plug interface 7 on the front panel of the adsorption device body 1, and the limiting groove 6 matches the limiting plate 9 for accommodating the limiting plate 9. The elastic member 12 is a spring.

[0033] Reference Figure 10 Second chute slots 16 are symmetrically defined within the upper portion of the movable frame 2 and on either side of the movable slot 14. A second connecting slot 203 is defined within each second chute slot 16. A connecting plate 18 is mounted within each second chute slot 16, near the second connecting slot 203. One side of the connecting plate 18 is secured to a plug post 15, which slides within the second connecting slot 203 and has a semicircular contact head 151 at its end. The other side of the connecting plate 18 is secured to one end of a second elastic member 17, which is positioned within the second chute slot 16. The other end of the elastic member 17 is secured to the inner wall of the second chute slot 16. Multiple auxiliary slots 13 are defined on both the left and right sides of the plug block 4. The side of the second elastic member 17, away from the connecting plate 18, is secured to the inner wall of the second chute slot 16. The second elastic member 17 is a spring.

[0034] Reference Figure 1 、 Figure 2 and Figure 8 The cross sections of the mounting groove 5 and the mounting plate 8 are both inverted T-shaped.

[0035] Reference Figure 7 The plug block 4 is in the shape of an elongated block, and has arcuate grooves 401 on its left and right sides along the vertical direction, which match the semicircular contacts 151 at the ends of the plug posts 15. Multiple auxiliary grooves 13 are spaced apart vertically within the arcuate grooves 401. The auxiliary grooves 13 are arcuate grooves that match the semicircular contacts 151. When the plug block 4 moves, the semicircular contacts 151 at the ends of the plug posts 15 can fall into and slide out of the auxiliary grooves 13.

[0036] When the present invention is in use, the two pulling blocks 10 are pulled to move toward each other along the slide groove 11, and at the same time, the limiting plate 9 on the movable frame 2 is gradually retracted into the slide groove 11, and the elastic member 12 is squeezed to make it compressed in the slide groove 11. At this time, the limiting plate 9 is separated from the limiting groove 6, and then the movable frame 2 can be pulled forward, driving the mounting plate 8 at its bottom to slide forward along the mounting groove 5, and then synchronously driving the adsorption plate 3 to separate from the adsorption device body 1. At this time, the operator can directly clean the adsorption plate 3.

[0037] After the movable frame 2 is pulled out of the suction device body 1, the suction plate 3 is pulled upward. During this process, the plug-in block 4 on the suction plate 3 slides upward along the movable groove 14 of the movable frame 2. Since the plug-in block 4 has arcuate grooves 401 on both sides, and multiple auxiliary grooves 13 are spaced apart within the arcuate grooves 401, when the pin 15 contacts the arcuate grooves 401 but does not fall into the auxiliary grooves 13, the plug-in block 4 pushes the pin 15 toward the interior of the second chute 16, thereby driving the connecting plate 18 to push the second elastic member 17 along the inner wall of the second chute 16, causing the second elastic member 17 to enter a compressed state. As the plug-in block 4 moves, when the pin 15 falls into the auxiliary groove 13, the elastic force of the second elastic member 17 is released. Therefore, as the plug-in block 4 continues to move upward, the pin 15 continuously falls in and out of the auxiliary groove 13, causing the plug-in block 4 to vibrate, thereby shaking off dust or impurities on the suction plate 3, allowing the operator to further clean or replace the suction plate 3. After completion, the adsorption plate 3 is inserted downwardly into the movable frame 2 from the second plug-in port 201 . As the two plug-in blocks 4 are slidably connected with the movable grooves 14 , the adsorption plate 3 is inserted into the movable frame 2 .

[0038] After the adsorption plate 3 is cleaned or replaced, the movable frame 2 is reinserted into the adsorption device body 1 from the first plug interface 7 for reset. During the reset process, the two pull blocks 10 are pulled to move toward each other. When the movable frame 2 completely enters the adsorption device body 1, the pull blocks 10 are released, and the elastic force of the elastic member 12 is used to push the limiting plate 9 to reset and insert it into the limiting groove 6, thereby clamping and fixing the movable frame 2 and the adsorption device body 1 to complete the installation of the movable frame 2.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
