Description

Technical Field

[0001] This invention relates to the technical field of coalbed methane drainage equipment, and more particularly to a dedicated downhole direct-drive drainage equipment for coalbed methane. Background Technology

[0002] Coalbed methane (CBM) is an unconventional natural gas that is associated with coal and is self-generated and stored in coal seams in an adsorbed state. At present, CBM extraction generally follows the extraction mechanism of "drainage-pressure reduction-gas extraction". That is, water in the coal seam is drained through mechanical equipment to reduce the downhole pressure, so that the CBM adsorbed on the inner surface of the coal matrix pores is desorbed and transported to the wellbore through two different modes: diffusion and flow. This not only makes CBM, a clean energy source, available, but also greatly reduces the probability of gas explosion accidents during later coal mining operations.

[0003] Existing equipment filters coalbed methane through a filter screen and activated carbon plate inside the filter box during extraction. However, after prolonged use, the filter screen becomes clogged with foreign matter, and the activated carbon plate becomes saturated and fails. The filter screen inside the filter box is not only difficult for operators to clean, but it also makes it difficult to replace the activated carbon plate. Summary of the Invention

[0027] Example 1 Reference Figures 1-5 In the first embodiment of the present invention, a special downhole direct-drive drainage device for coalbed methane is provided. The filter box 102 is moved by the moving mechanism 200, which also facilitates the replacement of the activated carbon frame 104.

[0028] The sampling mechanism 100 includes a base 101, a filter box 102 is provided on the left side of the top of the base 101, a filter screen 103 is fixedly connected to the bottom inside the filter box 102, an activated carbon frame 104 is movably installed on the top of the filter screen 103, a connecting pipe 105 is fixedly connected to the top of the filter box 102, an air extraction pipe 106 is fixedly connected to the left side inside the base 101 and is connected to the filter box 102, a water extraction pipe 107 is fixedly connected to the right side inside the base 101, and a water pump 108 is fixedly installed on the right side of the top of the base 101 and is connected to the water extraction pipe 107. The moving mechanism 200 includes an electric slide rail 201, which is fixedly connected to the front and rear sides of the top left side of the base 101. Slider 202s are fixedly connected to the four corners of the bottom of the filter box 102. The sliders 202s are slidably connected to the electric slide rail 201. Pushing components 203 are provided on the front and rear sides of the bottom right side of the filter box 102. A positioning component 204 is fixedly connected to the right side of the activated carbon frame 104.

[0029] The pushing component 203 includes a mounting groove 203a, and tilting seats 203b are fixedly connected to the front and rear sides of the top of the base 101. An tilting block 203c is movably connected to the bottom inside the mounting groove 203a. The tilting block 203c is movably connected to the tilting seat 203b. A reset component 203d is fixedly connected to the right side of the top of the tilting block 203c.

[0030] The reset component 203d includes a spring 203d1, which is fixedly connected to the right side of the top of the tilting block 203c. The top end of the spring 203d1 is fixedly connected to the right side of the top of the inner wall of the mounting groove 203a. A telescopic protective sleeve 203d2 is fitted on the surface of the spring 203d1. The top end of the telescopic protective sleeve 203d2 is fixedly connected to the right side of the top of the inner wall of the mounting groove 203a, and the bottom end of the telescopic protective sleeve 203d2 is fixedly connected to the right side of the top of the tilting block 203c. The tilting block 203c is movably connected to the tilting seat 203b.

[0031] The positioning component 204 includes a positioning plate 204a. Positioning grooves 204b are provided on the front and rear sides of the bottom of the positioning plate 204a. An insert plate 204c is movably connected inside the positioning groove 204b. The bottom end of the insert plate 204c is fixedly connected to the top of the inclined block 203c.

[0032] The inclined surface of the inclined seat 203b is movably inlaid with a movable roller 205. Several movable rollers 205 are provided and are distributed at equal intervals. The inclined surface of the inclined block 203c is movably connected to the movable rollers 205.

[0033] The top of the exhaust pipe 106 is fixedly connected to a sealing disc 206, and the bottom of the filter box 102 is fixedly installed with a sealing ring 207, which is movably connected to the sealing disc 206.

[0034] A protective sealing cover 208 is fixedly connected to the bottom of the filter box 102, and the protective sealing cover 208 is movably connected to the sealing plate 206.

[0035] Specifically, the use of the push component 203 enables the filter box 102 to move to the right and push the insert plate 204c upward, while simultaneously positioning the filter box 102.

[0036] The reset component 203d can drive the tilt block 203c to move downward and reset when it is separated from the tilt seat 203b, so that the tilt block 203c can drive the insert plate 204c to move downward, while the telescopic protective sleeve 203d2 can protect the spring 203d1.

[0037] The insert plate 204c inside the positioning component 204 is inserted upward into the positioning groove 204b to position the activated carbon frame 104. When the insert plate 204c is separated downward from the positioning groove 204b, the positioning of the activated carbon frame 104 is released, making it easier to replace the activated carbon frame 104.

[0038] The use of movable roller 205 can reduce the friction when the inclined block 203c contacts the inclined surface of the inclined seat 203b.

[0039] The use of sealing disc 206 and sealing ring 207 ensures that there will be no leakage when the filter box 102 is connected to the exhaust pipe 106.

[0040] The use of the protective sealing cover 208 can protect the sealing disc 206 and the sealing ring 207.

[0041] Furthermore, when the activated carbon frame 104 inside the filter screen 103 is replaced, the filter box 102 is moved to the left on the top of the base 101 by the cooperation of the electric slide rail 201 and the slider 202.

[0042] As the filter box 102 moves to the left, it will cause the inclined block 203c inside the mounting groove 203a to move to the left, so that the inclined block 203c can separate from the inclined seat 203b after moving to the left. At the same time, the spring 203d1 on the inner wall of the mounting groove 203a can drive the inclined block 203c to move downward through its own elastic force. After the inclined block 203c moves downward, it can drive the insert plate 204c to move downward inside the mounting groove 203a, thereby separating the insert plate 204c from the positioning groove 204b on the positioning plate 204a, thereby releasing the positioning of the activated carbon frame 104, making it convenient for the operator to replace the activated carbon frame 104.

[0043] After the activated carbon frame 104 is replaced, the filter box 102 is moved to the right on the top of the base 101 by the cooperation of the electric slide rail 201 and the slider 202.

[0044] When the filter box 102 moves to the right, it will cause the protective sealing cover 208 and the sealing ring 207 to come into contact with the sealing plate 206, thereby ensuring that there will be no leakage when the exhaust pipe 106 is connected to the filter box 102.

[0045] As the filter box 102 moves to the right, it will cause the tilting block 203c to move to the right, so that the tilting block 203c contacts the movable roller 205 on the inclined surface of the tilting seat 203b, thereby causing the tilting block 203c to move upward. This allows the tilting block 203c to squeeze the spring 203d1 and simultaneously drive the insert plate 204c to move upward and insert into the positioning groove 204b inside the positioning plate 204a, thereby positioning the activated carbon frame 104 inside the filter box 102.

[0046] It should be noted that the connecting pipe 105 is connected to an external air pump.

[0047] Example 2 Reference Figures 1-5 In a second embodiment of the present invention, a special downhole direct-drive drainage device for coalbed methane is provided, which, through a cleaning mechanism 300, achieves mobile cleaning while assisting in the discharge of impurities.

[0048] The cleaning mechanism 300 includes a sealing groove 301, which is located at the bottom right side of the filter box 102. A vibration component 302 is fixedly connected to the bottom of the filter screen 103. An outlet 303 is provided on the left side of the bottom of the filter box 102. A sealing plate 304 is movably connected to the left side of the bottom of the filter box 102. Pulling components 305 are fixedly connected to the front and rear sides of the top of the sealing plate 304. An opening component 306 is fixedly connected to the right side of the sealing plate 304.

[0049] The vibration assembly 302 includes a connecting seat 302a, a sealing block 302b movably connected inside the sealing groove 301, a striking spring plate 302c fixedly connected to the left end of the sealing block 302b, the right side of the sealing block 302b fixedly connected to the left side of the connecting seat 302a, and a protrusion 302d fixedly connected to the bottom of the filter screen 103. Several protrusions 302d are arranged and are evenly distributed. The protrusions 302d are movably connected to the striking spring plate 302c.

[0050] The pulling assembly 305 includes a sliding block 305a, which is fixedly connected to the front and rear sides of the top of the sealing plate 304. Sliding grooves 305b are provided on the front and rear sides of the bottom left side of the filter box 102. The sliding block 305a is movably connected to the sliding groove 305b. A tension spring 305c is fixedly connected to the left side of the inner wall of the sliding groove 305b. The right end of the tension spring 305c is fixedly connected to the left side of the sliding block 305a.

[0051] The opening component 306 includes a contact plate 306a, and a contact seat 306b is fixedly connected to the front and rear sides of the top left side of the base 101. The contact plate 306a and the contact seat 306b are movably connected.

[0052] Specifically, the vibration component 302 can vibrate the filter screen 103 when the filter box 102 moves, so that the impurities attached to the filter screen 103 can be vibrated and fall downwards, thereby assisting in the cleaning of the filter screen 103.

[0053] The pull assembly 305 ensures that when the filter box 102 is connected to the air extraction pipe 106, the sealing plate 304 seals the outlet 303, and at the same time enables the sealing plate 304 to be reset.

[0054] When the filter box 102 moves to the left, the opening component 306 can push the sealing plate 304, thereby releasing the sealing barrier of the sealing plate 304 on the discharge port 303, so that the impurities on the base of the filter screen 103 can be discharged through the discharge port 303.

[0055] Furthermore, as the filter box 102 moves to the left, it will cause the filter screen 103 to move to the left as well. When the filter screen 103 moves to the left, the bottom protrusion 302d will come into contact with the striking spring plate 302c, so that the striking spring plate 302c can strike the filter screen 103 as the filter screen 103 moves, thereby causing the dust attached to the filter screen 103 to fall down after being vibrated.

[0056] At the same time, when the filter box 102 moves to the left, it will drive the sealing plate 304 to move to the left, so that the contact plate 306a on the right side of the sealing plate 304 can contact the contact seat 306b on the base 101. As the filter box 102 moves, the sealing plate 304 can release the seal on the outlet 303. At the same time, the sealing plate 304 will stretch the tension spring 305c on the inner wall of the sliding groove 305b through the sliding block 305a.

[0057] This allows dust falling from the filter screen 103 to slide off the inclined inner wall of the filter box 102 and be discharged through the outlet 303.

[0058] When the filter box 102 moves to the right, it will cause the protective sealing cover 208 and the sealing ring 207 to come into contact with the sealing plate 206, thereby ensuring that there will be no leakage when the exhaust pipe 106 is connected to the filter box 102.

[0059] As the filter box 102 moves to the right, it will cause the tilting block 203c to move to the right, so that the tilting block 203c contacts the movable roller 205 on the inclined surface of the tilting seat 203b, thereby causing the tilting block 203c to move upward. This allows the tilting block 203c to squeeze the spring 203d1 and simultaneously drive the insert plate 204c to move upward and insert into the positioning groove 204b inside the positioning plate 204a, thereby positioning the activated carbon frame 104 inside the filter box 102.

[0060] At the same time, when the filter box 102 moves to the right, the contact seat 306b will separate from the contact plate 306a. At this time, the tension spring 305c inside the sliding groove 305b can drive the sliding block 305a to move to the left through its own tension, so that the sliding block 305a can drive the sealing plate 304 to reset, thereby enabling the sealing plate 304 to seal the outlet 303 at the bottom of the filter box 102.

[0061] At the same time, the sealing block 302b on the connector 302a will seal the sealing groove 301 again.

[0062] It should be noted that the bottom of the inner wall of filter screen 103 is set at an angle.

[0063] The remaining structure is the same as that in Example 1.

[0064] Example 3 Reference Figures 1-5 This is the third embodiment of the present invention, which differs from the second embodiment in that it is a special downhole direct-drive drainage and extraction device for coalbed methane.

[0065] When the activated carbon frame 104 inside the filter screen 103 is replaced, the filter box 102 is moved to the left on the top of the base 101 by the cooperation of the electric slide rail 201 and the slider 202.

[0066] As the filter box 102 moves to the left, it will cause the inclined block 203c inside the mounting groove 203a to move to the left, so that the inclined block 203c can separate from the inclined seat 203b after moving to the left. At the same time, the spring 203d1 on the inner wall of the mounting groove 203a can drive the inclined block 203c to move downward through its own elastic force. After the inclined block 203c moves downward, it can drive the insert plate 204c to move downward inside the mounting groove 203a, thereby separating the insert plate 204c from the positioning groove 204b on the positioning plate 204a, thereby releasing the positioning of the activated carbon frame 104, making it convenient for the operator to replace the activated carbon frame 104.

[0067] As the filter box 102 moves to the left, it will cause the filter screen 103 to move to the left. When the filter screen 103 moves to the left, the bottom protrusion 302d will come into contact with the striking spring plate 302c. The striking spring plate 302c can strike the filter screen 103 as the filter screen 103 moves, so that the dust attached to the filter screen 103 can fall down after being vibrated.

[0068] At the same time, when the filter box 102 moves to the left, it will drive the sealing plate 304 to move to the left, so that the contact plate 306a on the right side of the sealing plate 304 can contact the contact seat 306b on the base 101. As the filter box 102 moves, the sealing plate 304 can release the seal on the outlet 303. At the same time, the sealing plate 304 will stretch the tension spring 305c on the inner wall of the sliding groove 305b through the sliding block 305a.

[0069] This allows dust falling from the filter screen 103 to slide off the inclined inner wall of the filter box 102 and be discharged through the outlet 303.

[0070] After the activated carbon frame 104 is replaced, the filter box 102 is moved to the right on the top of the base 101 by the cooperation of the electric slide rail 201 and the slider 202.

[0071] When the filter box 102 moves to the right, it will cause the protective sealing cover 208 and the sealing ring 207 to come into contact with the sealing plate 206, thereby ensuring that there will be no leakage when the exhaust pipe 106 is connected to the filter box 102.

[0072] As the filter box 102 moves to the right, it will cause the tilting block 203c to move to the right, so that the tilting block 203c contacts the movable roller 205 on the inclined surface of the tilting seat 203b, thereby causing the tilting block 203c to move upward. This allows the tilting block 203c to squeeze the spring 203d1 and simultaneously drive the insert plate 204c to move upward and insert into the positioning groove 204b inside the positioning plate 204a, thereby positioning the activated carbon frame 104 inside the filter box 102.

[0073] At the same time, when the filter box 102 moves to the right, the contact seat 306b will separate from the contact plate 306a. At this time, the tension spring 305c inside the sliding groove 305b can drive the sliding block 305a to move to the left through its own tension, so that the sliding block 305a can drive the sealing plate 304 to reset, thereby enabling the sealing plate 304 to seal the outlet 303 at the bottom of the filter box 102.

[0074] At the same time, the sealing block 302b on the connector 302a will seal the sealing groove 301 again.

[0075] In summary, the moving mechanism 200 and the cleaning mechanism 300 facilitate the replacement of the activated carbon frame 104 while simultaneously cleaning the filter screen 103 through vibration.
