Description

Technical Field

[0001] This invention relates to the field of anaerobic treatment technology, specifically to a harmless treatment pond for diseased and dead livestock and poultry. Background Technology

[0002] If diseased or dead livestock and poultry are carelessly discarded or improperly disposed of, they can easily lead to the spread of diseases, soil pollution, and water pollution, posing a serious threat to the ecological environment and public health. Currently, the harmless treatment of diseased and dead livestock and poultry mostly adopts anaerobic fermentation. By anaerobic decomposing the diseased and dead livestock and poultry in a treatment pond, the carcasses can be degraded and rendered harmless, while simultaneously producing biogas, mainly composed of methane, enabling energy recovery and utilization.

[0003] To achieve effective collection of methane gas, existing harmless treatment ponds typically have a flow guide hood installed at the top of the pond to gather the biogas produced during fermentation. The biogas is then transported to subsequent collection or utilization devices through an exhaust pipe above the flow guide hood. The flow guide hood and the exhaust pipe are generally fixedly connected by flanges to ensure ease of assembly and structural strength.

[0004] Currently, the biogas produced by the anaerobic fermentation of diseased and dead livestock and poultry in the harmless treatment ponds contains a large amount of water vapor and corrosive gases. The sealing gaskets at the flange connection are exposed to high temperature, high humidity and corrosive gas environment for a long time, which makes them prone to aging, cracking and failure. In addition, the biogas production process is intermittent and fluctuating, and the pressure in the pond is constantly changing. This causes the flange connection to be subjected to repeated pressure impacts, which can easily cause the connecting bolts to loosen and the flange sealing surface to not fit tightly, resulting in a continuous decline in sealing performance and aggravating the leakage of fermentation gas.

[0005] To address the above issues, a harmless treatment pond for diseased and dead livestock and poultry is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a harmless treatment pool for diseased and dead livestock and poultry. By using this device, the problem of continuous decline in sealing performance and aggravated leakage of fermentation gas caused by long-term use of flange connections is solved.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A harmless treatment pool for diseased and dead livestock and poultry includes a treatment pool body and a first flange pipe disposed on the top of the treatment pool body. A second flange pipe is installed at one end of the first flange pipe, and a gas collection device is provided at one end of the second flange pipe. A pressure differential sensor is installed inside the first flange pipe. A fixed plate is fixedly installed on the surface of the second flange pipe, and a threaded pipe is rotatably connected to the surface of the second flange pipe. A driving device is fixedly installed on one side of the fixed plate, and the driving device is drivenly connected to the threaded pipe. The pressure differential sensor is electrically connected to the driving device through a controller. A sealing device is threadedly connected to the surface of the threaded pipe. Two limiting pushers are slidably engaged on the surface of the fixed plate, and the sealing device is slidably connected to the two limiting pushers. A one-way air inlet is installed inside the sealing device, and an air bladder is also installed inside the sealing device. The one-way air inlet is connected to the air bladder, and the two limiting pushers are in contact with the air bladder. Gas collecting devices are installed on both sides of the sealing device, and the gas collecting devices are connected to the air bladder. A sealing device is fixedly installed on both sides of the fixed plate, and the sealing device is slidably connected to the gas collecting device.

[0009] Furthermore, a support plate is fixedly installed on the outside of the second flange pipe, and the threaded pipe is rotatably connected to the support plate.

[0010] Furthermore, the gas collecting device includes a collecting tank and a connecting pipe disposed on one side of the collecting tank. A valve is installed at one end of the connecting pipe, and the connecting pipe is connected to a second flange pipe through the valve. An exhaust pipe is provided on one side of the collecting tank.

[0011] Furthermore, springs are installed on the inside of both sides of the fixed disk, and an arc-shaped block is fixedly installed on one end of the spring. The arc-shaped block is slidably connected to the fixed disk and is slidably engaged with the limiting pusher.

[0012] Furthermore, a first gear is fixedly installed at one end of the threaded tube, and a ring is fixedly installed inside the threaded tube. Several balls are rotatably connected inside the ring, and all of the balls are in contact with the second flange tube. The driving component includes a housing and a motor fixed inside the housing. The housing is fixedly connected to a fixed plate, and a second gear is fixedly installed at the output end of the motor. The second gear meshes with the first gear.

[0013] Furthermore, the sealing element includes a sealing cover and a threaded sleeve fixed to one side of the sealing cover. The sealing cover is slidably connected to two limiting pushers, and the threaded sleeve is threadedly connected to a threaded pipe.

[0014] Furthermore, the limiting pusher includes a slide rod and a compression ring fixed to one end of the slide rod. The slide rod is slidably connected to the fixed plate and the sealing cover, and the compression ring is slidably connected to the sealing cover. Two sets of corresponding arc grooves are opened on the surface of the slide rod, and the arc block is slidably connected to the arc groove.

[0015] Furthermore, the one-way air intake component includes a concave ring gasket and several one-way valves disposed on one side of the concave ring gasket. The concave ring gasket is in contact with the outer wall of the first flange pipe and the second flange pipe. One end of the one-way valve is connected to a bellows, and one end of the bellows is connected to the airbag.

[0016] Furthermore, the gas collecting component includes a gas collecting tank and a fixing frame fixed to the surface of the gas collecting tank. The fixing frame is fixedly connected to the sealing cover. One end of the gas collecting tank is provided with an air outlet pipe, and the other end of the gas collecting tank is provided with an air guide pipe. The air guide pipe passes through and is connected to one side of the sealing cover. The air guide pipe communicates with the airbag, and a sealing pipe is fixedly installed on the surface of the air guide pipe.

[0017] Furthermore, the sealing component includes a fixing rod and a strip-shaped hole extending through the surface of the fixing rod. One end of the fixing rod is fixedly connected to the fixing plate, and the fixing rod is slidably connected to the air guide tube and the sealing tube.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By installing a pressure differential sensor inside the first flange pipe, the leakage status at the connection between the first flange pipe and the second flange pipe can be monitored in real time. Once a leak occurs, the driving component, threaded pipe and sealing component will quickly act to wrap and seal the connection between the first flange pipe and the second flange pipe, suppressing the leakage of fermentation gas from the source and significantly improving the fermentation gas collection rate and system safety.

[0019] 2. Leaking gas enters the air bladder through the one-way air inlet, causing the air bladder to automatically expand and tightly fit against the outer wall of the first flange pipe, forming an adaptive flexible sealing structure. No external air source is required; the sealing reliability can be improved by relying on the pressure of the leaking gas itself, reducing the problems of gas leakage caused by the easy aging and loosening of traditional flange seals.

[0020] 3. The combination of the one-way air intake and the sealing component ensures that gas can only enter the airbag and cannot flow out in the opposite direction, ensuring that the airbag always remains in an inflated and compressed state, unaffected by system pressure fluctuations, and providing a long-lasting and reliable sealing effect.

[0021] 4. When the sealing component is in a sealed state, it closes the gas collecting component, ensuring that the airbag inflates normally. When resetting, the gas collecting component is connected to the airbag, and the gas in the airbag is recovered to the gas collecting component, avoiding the direct emission of fermentation gas, improving energy utilization, and eliminating the risk of gas leakage during maintenance.

[0022] 5. Therefore, emergency sealing of leaks can be completed without stopping fermentation and gas collection, allowing time for subsequent inspection and maintenance, ensuring the continuous and stable operation of the treatment tank, and improving the continuity and reliability of the harmless treatment system for diseased and dead livestock and poultry.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To address the technical problem of flange connections experiencing a continuous decline in sealing performance and exacerbating fermentation gas leakage due to prolonged use, such as... Figures 1-11 As shown, the following preferred technical solutions are provided: like Figure 1 and Figure 2 As shown, a harmless treatment pool for diseased and dead livestock and poultry includes a treatment pool body 1 and a first flange pipe 2 installed on the top of the treatment pool body 1. A second flange pipe 3 is installed at one end of the first flange pipe 2. The first flange pipe 2 and the second flange pipe 3 are connected by flanges, which facilitates installation, disassembly and subsequent maintenance, ensures the sealing and structural stability of the gas conveying channel, provides a basis for the smooth entry of fermentation gas into the gas collection device 4, and improves the gas conveying efficiency. At the same time, the first flange pipe 2 and the second flange pipe 3 are both made of rigid materials. A gas collection device 4 is provided at one end of the second flange pipe 3. By setting the first flange pipe 2 and the second flange pipe 3 on the top of the treatment pool body 1, the fermentation gas is centrally conveyed. With the help of the gas collection device 4, combustible gases such as methane are recovered and utilized. At the same time, the harmless and reduced-volume treatment of diseased and dead livestock and poultry is achieved, and the purpose of energy utilization is also achieved.

[0027] The first flange 2 is equipped with a differential pressure sensor 5, which can monitor the flange connection for leaks in real time and accurately, enabling automatic identification of leaks without manual inspection, improving the system's intelligence level, timely detection of safety hazards, and preventing large-scale methane leaks from causing danger. The second flange 3 has a fixed plate 6 fixedly installed on its surface, and a threaded pipe 7 is rotatably connected to it. A drive component 8 is fixedly installed on one side of the fixed plate 6, and the drive component 8 is connected to the threaded pipe 7. The differential pressure sensor 5 is electrically connected to the drive component 8 through a controller. When the differential pressure sensor 5 detects a leak, it can automatically drive the threaded pipe 7 to rotate, realizing the automatic advancement and reset of the seal 9. This requires no manual operation, has a fast response speed, and can quickly activate the emergency seal at the moment of leakage, improving system safety. The threaded pipe 7 is threadedly connected to the seal 9, which is threadedly engaged with the threaded pipe 7. It can move axially and completely wrap the connection between the first flange 2 and the second flange 3, achieving rapid emergency sealing from the outside, inhibiting the diffusion of leaked gas, reducing the amount of gas leakage, and providing time for subsequent enhanced sealing.

[0028] Two limiting pushers 10 are slidably engaged on the surface of the fixed plate 6, and the sealing element 9 is slidably connected to the two limiting pushers 10. The two limiting pushers 10 can move the sealing element 9, so that the sealing element 9 can only move up and down, preventing rotation. A one-way air inlet 20 is installed inside the sealing element 9, and an air bladder 30 is also installed inside the sealing element 9. The air bladder 30 is made of corrosion-resistant, high-temperature resistant and wear-resistant materials, and the one-way air inlet 20 is connected to the air bladder 30. The one-way air inlet 20 can guide the gas leaking from the connection between the first flange pipe 2 and the second flange pipe 3 into the air bladder 30. The pressure of the leaking gas itself causes the air bladder 30 to expand automatically, forming a flexible and tight seal, further improving the sealing effect. The one-way air inlet 20 allows gas to enter but not exit, ensuring that the air bladder 30 is continuously in an expanded and compressed state, unaffected by system pressure fluctuations, and the seal is long-lasting and stable, fundamentally solving the problems of flange loosening and aging leakage.

[0029] Both limiting pushers 10 are in contact with the airbag 30. The limiting pushers 10 can contact or separate from the airbag 30 to compress and release the airbag 30, controlling the inflation and deflation of the airbag 30. Gas collecting components 40 are installed on both sides of the sealing component 9 and are connected to the airbag 30. The gas collecting components 40 are connected to the airbag 30 and can collect leaked gas in the airbag 30 when the device is reset, preventing the gas from being directly discharged into the atmosphere, improving the methane recovery rate, realizing full utilization of energy, and eliminating safety hazards and environmental pollution during maintenance. The fixed plate 6 is fixedly installed with sealing components 50 on both sides and the sealing components 50 are slidably connected to the gas collecting components 40. After the sealing component 9 is in place, the sealing components 50 can automatically seal the gas collecting components 40 to ensure that the airbag 30 is normally inflated and does not depressurize. When the sealing component 9 is reset, the gas collecting components 40 are automatically opened to realize the recovery of gas in the airbag 30.

[0030] Dead livestock and poultry are placed in the treatment tank 1 for anaerobic fermentation, decomposing to produce fermentation gas, mainly methane. The gas is transported to the gas collection device 4 through the first flange pipe 2 and the second flange pipe 3 for collection, and then processed and utilized in subsequent processes. When the connection between the first flange pipe 2 and the second flange pipe 3 leaks due to aging and loosening of the seal after long-term use, the pressure difference sensor 5 installed inside the first flange pipe 2 detects the abnormal pressure change inside and outside the pipe in real time and transmits the signal to the controller (the controller is existing technology and is not shown in the figure). The controller starts the drive device 8, which drives the threaded pipe 7 to rotate. The threaded pipe 7 drives the sealing device 9 to move axially through the threaded engagement. In the initial state, the limiting push device 10 is engaged and positioned with the fixed plate 6. When the sealing device 9 moves down, it drives the limiting push device 10 to move synchronously, so that the sealing device 9 quickly covers the first flange pipe 2 and the second flange pipe 3, realizing an outer wrapping emergency seal and suppressing gas leakage.

[0031] When the sealing element 9 moves to the set position, the limiting pusher 10 re-engages with the fixed plate 6 and locks itself. At the same time, the limiting pusher 10 separates from the airbag 30, releasing the squeezing constraint on the airbag 30. At this time, the sealing element 50 seals the gas collecting element 40, disconnecting the gas collecting element 40 from the airbag 30. At this time, the one-way air inlet 20 is tightly attached to the connection between the first flange pipe 2 and the second flange pipe 3. The leaked gas continuously enters the interior of the airbag 30 through the one-way air inlet 20. Under the action of gas pressure, the airbag 30 expands and tightly adheres to the outer wall of the first flange pipe 2, forming an adaptive flexible seal between the sealing element 9 and the airbag 30, further improving the sealing effect and preventing continuous gas leakage. After the fermentation gas is collected, the controller controls the drive element 8 to drive the threaded pipe 7 to rotate in the opposite direction, driving the sealing element 9 to move upward and reset. During the upward movement of the sealing element 9, the sealing element 50 gradually separates from the gas collecting element 40, and the gas collecting element 40 and the airbag 30 are reconnected.

[0032] Since the two limiting pushers 10 are engaged with the fixed plate 6, when the airbag 30 moves upward, the limiting pushers 10 squeeze the airbag 30, forcing the leaked gas collected in the airbag 30 into the gas collecting component 40 for recovery, thus preventing the gas from being directly discharged. Subsequently, the staff can inspect and maintain the first flange pipe 2 and the second flange pipe 3, and uniformly export and process the gas in the gas collecting component 40. Therefore, by setting a pressure differential sensor 5 inside the first flange pipe 2, the leakage status at the connection between the first flange pipe 2 and the second flange pipe 3 can be monitored in real time. Once there is a leak, the drive component 8, the threaded pipe 7, and the sealing component 9 act quickly to wrap and seal the connection between the first flange pipe 2 and the second flange pipe 3, suppressing the leakage of fermentation gas from the source, significantly improving the fermentation gas collection rate and system safety. The leaked gas enters the airbag 30 through the one-way air inlet component 20, causing the airbag 30 to automatically expand and tightly fit the outer wall of the first flange pipe 2, forming an adaptive flexible sealing structure without the need for an external gas source.

[0033] The sealing reliability can be improved by relying on the pressure of the leaking gas itself, reducing the problems of gas leakage caused by the aging and loosening of traditional flange seals. The one-way air inlet 20 and the sealing part 50 work together to ensure that the gas can only enter the air bag 30 and cannot flow out in reverse, ensuring that the air bag 30 always remains in an expanded and compressed state, unaffected by system pressure fluctuations, and the sealing effect is long-lasting and reliable. When the sealing part 50 is in the sealed state, it closes the gas collecting part 40, ensuring that the air bag 30 is normally inflated. When resetting, the gas collecting part 40 is connected to the air bag 30, and the gas in the air bag 30 is recovered to the gas collecting part 40, avoiding the direct emission of fermentation gas, improving energy utilization, and eliminating the risk of gas leakage during maintenance. Therefore, emergency sealing of leakage can be completed without stopping fermentation and gas collection, leaving time for subsequent maintenance and ensuring the continuous and stable operation of the treatment tank body 1, improving the continuity and reliability of the harmless treatment system for dead livestock and poultry.

[0034] like Figure 3 and Figure 4 As shown, a support plate 31 is fixedly installed on the outside of the second flange pipe 3, and the threaded pipe 7 is rotatably connected to the support plate 31. The support plate 31 can provide stable support for the rotation of the threaded pipe 7, ensuring the stability of the threaded pipe 7 during rotation. The gas collection component 4 includes a collection tank 41 and a connecting pipe 42 connected to one side of the collection tank 41. The collection tank 41 can centrally store gases such as methane produced by the anaerobic fermentation of dead livestock and poultry. A valve 43 is installed at one end of the connecting pipe 42, and the connecting pipe 42 is connected to the second flange pipe 3 through the valve 43. The valve 43 can open or close the gas passage at any time according to the usage requirements. An exhaust pipe 44 is provided on one side of the collection tank 41. The connecting pipe 42 directly connects the collection tank 41 and the second flange pipe 3, forming a closed and continuous gas transportation channel, reducing the resistance and leakage risk of gas during transportation, ensuring that the methane produced by fermentation can enter the collection tank 41 for storage efficiently, and improving the gas collection and utilization rate.

[0035] like Figure 5 and Figure 6 As shown, springs 61 are installed on both sides of the fixed disk 6. An arc-shaped block 62 is fixedly installed on one end of the spring 61 and is slidably connected to the fixed disk 6. The arc-shaped block 62 is slidably engaged with the limiting pusher 10. The spring 61 can continuously provide an outward elastic thrust to the arc-shaped block 62, so that the arc-shaped block 62 and the limiting pusher 10 can achieve automatic and stable sliding engagement. The arc-shaped block 62 adopts an arc surface design, which can form a smooth sliding cooperation with the limiting pusher 10 during the up and down movement of the limiting pusher 10, avoiding jamming and stuck phenomena, ensuring smooth movement of the sealing element 9, and improving the operational stability of the device.

[0036] like Figure 4 , Figure 7 and Figure 8 As shown, a first gear 71 is fixedly installed at one end of the threaded pipe 7. The first gear 71 realizes stable transmission between the driving component 8 and the threaded pipe 7, ensuring precise and efficient power transmission. A ring 72 is fixedly installed inside the threaded pipe 7. Several balls 73 are rotatably connected inside the ring 72, and all balls 73 are in contact with the second flange pipe 3. The ring 72 and the balls 73 cooperate to reduce the rotational resistance of the threaded pipe 7 and improve the smoothness of operation. The ring 72 provides a stable mounting and rotation carrier for the balls 73. The balls 73 roll contact with the surface of the second flange pipe 3, converting the sliding friction between the threaded pipe 7 and the second flange pipe 3 into rolling friction, which greatly reduces the frictional resistance when the threaded pipe 7 rotates, allowing the threaded pipe 7 to rotate flexibly under the drive of the driving component 8, reducing the load on the driving component 8, reducing component wear, and avoiding rotational jamming or stuck situations, ensuring a rapid response to emergency sealing actions.

[0037] like Figure 4As shown, the drive component 8 includes a housing 81 and a motor 82 fixed inside the housing 81. The housing 81 is fixedly connected to the fixed plate 6. A second gear 83 is fixedly installed at the output end of the motor 82. The second gear 83 meshes with the first gear 71. The housing 81 provides a stable mounting carrier for the internal motor 82, ensuring that the motor 82 does not shake or shift during operation. When the pressure differential sensor 5 inside the first flange pipe 2 detects air leakage at the connection between the first flange pipe 2 and the second flange pipe 3, the pressure differential sensor 5 transmits a signal to the controller. The controller starts the motor 82, and the output end of the motor 82 drives the second gear 83 to rotate at a constant speed. The wheel 83 meshes with the first gear 71 at one end of the threaded tube 7. The rotation of the second gear 83 will synchronously drive the first gear 71 to rotate, thereby driving the threaded tube 7 to rotate coaxially around the second flange tube 3. When the threaded tube 7 rotates, it drives the seal 9 to move axially along the second flange tube 3 through the threaded engagement with the seal 9, thereby achieving emergency sealing at the connection between the first flange tube 2 and the second flange tube 3. When the seal 9 needs to be reset, the controller controls the motor 82 to rotate in the opposite direction, driving the second gear 83, the first gear 71 and the threaded tube 7 to rotate in the opposite direction, thereby driving the seal 9 to reset upward, completing the exhaust of the airbag 30 and the gas recovery of the gas collection component 40.

[0038] like Figure 9 and Figure 10 As shown, the sealing element 9 includes a sealing cover 91 and a threaded sleeve 92 fixed to one side of the sealing cover 91. The sealing cover 91 achieves a complete wrapping seal at the connection between the first flange pipe 2 and the second flange pipe 3, improving the reliability of the emergency seal. The sealing cover 91 adopts a structural design that adapts to the dimensions of the first flange pipe 2 and the second flange pipe 3, and can completely wrap the flange connection between the first flange pipe 2 and the second flange pipe 3 to form an outer layer of airtight protection. This effectively blocks the diffusion of leaked gas from the outside, providing a stable airtight environment for the subsequent inflation of the airbag 30 to strengthen the seal. This provides double protection for the sealing effect and prevents continuous methane leakage. To minimize leakage and reduce safety hazards, the sealing cover 91 is slidably connected to two limiting pushers 10, and the threaded sleeve 92 is threadedly connected to the threaded pipe 7. The threaded sleeve 92 achieves precise matching with the threaded pipe 7, ensuring that the sealing cover 91 moves smoothly. The rotational motion of the threaded pipe 7 is smoothly converted into the axial linear motion of the sealing cover 91, ensuring that the sealing cover 91 can move at a uniform speed and smoothly along the second flange pipe 3, avoiding movement deviation and jamming. This ensures that the sealing cover 91 can quickly and accurately cover the connection between the first flange pipe 2 and the second flange pipe 3, achieving timely emergency sealing and reducing methane leakage.

[0039] like Figures 5-7As shown, the limiting pusher 10 includes a slide rod 101 and a compression ring 102 fixed to one end of the slide rod 101. The slide rod 101 is slidably connected to the fixed plate 6 and the sealing cover 91. The compression ring 102 is slidably connected to the sealing cover 91. Two sets of corresponding arc grooves 103 are opened on the surface of the slide rod 101, and the arc block 62 is slidably connected to the arc groove 103. When the pressure differential sensor 5 detects air leakage at the flange connection, the motor 82 drives the threaded pipe 7 to rotate. When the sealing cover 91 moves downward through the threaded sleeve 92, the sealing cover 91 drives the slide rod 101 to move downward synchronously through sliding engagement. Thus, the arc block 62 is stuck in the arc groove 103. Therefore, the slide rod 101 will drive the compression ring 102 at one end to move upward a certain distance and separate from the airbag 30. When the sealing cover 91 continues to move, the compression ring 102 will drive the slide rod 101 to move downward. The arc groove 103 on the surface of the slide rod 101 slides relative to the arc block 62 on the fixed plate 6. Then the arc groove 103 squeezes the arc block 62 and separates it. When the sealing cover 91 moves to the set sealing position, another set of arc grooves 103 on the slide rod 101 is just aligned with the arc block 62. The arc block 62 is stuck into the arc groove 103 under the elastic force of the spring 61, realizing the snap-fit ​​positioning of the slide rod 101 and the fixed plate 6.

[0040] At this point, the compression ring 102 separates from the airbag 30, releasing the compression on the airbag 30. This allows the airbag 30 to inflate through the one-way air intake 20 to achieve a reinforced seal. When the sealing cover 91 needs to be reset, the motor 82 drives the threaded tube 7 to rotate in the opposite direction, causing the sealing cover 91 to move upward. The sealing cover 91 then drives the slide rod 101 to move upward synchronously. Since the elastic force of the spring 61 is greater than the friction between the fixed plate 6 and the sealing cover 91, as well as the force generated after the airbag 30 expands, the compression ring 102 will first compress the airbag 30 until the arc block 62 compresses the spring 61 and retracts the fixed plate 6. Inside, the locking limit is released. When the sealing cover 91 is reset, another set of arc grooves 103 on the slide rod 101 re-engages with the arc block 62 to achieve the initial position positioning. Even if the arc block 62 is released from the sliding rod 101 and pushes the sliding rod 101 to move upward, the squeezing force of the spring 61 pushing the arc block 62 to contact the sliding rod 101 and the friction between the sliding rod 101, the fixed plate 6 and the sealing cover 91 can ensure that the squeezing ring 102 can continuously squeeze the airbag 30, reducing the amount of gas inside the gas collecting component 40 returning to the airbag 30.

[0041] To address the technical problem of poor sealing performance when using only a single structure, such as Figure 7 , Figure 10 and Figure 11 As shown, the following preferred technical solutions are provided: like Figure 10As shown, the one-way air intake component 20 includes a concave ring gasket 201 and several one-way valves 202 disposed on one side of the concave ring gasket 201. The concave ring gaskets 201 are all in contact with the outer walls of the first flange pipe 2 and the second flange pipe 3. The concave ring gaskets 201 conform to the outer walls of the flanges, achieving precise collection of leaked gas and improving intake efficiency. The concave ring gaskets 201 adopt a concave structural design, enabling precise contact with the outer walls of the first flange pipe 2 and the second flange pipe 3, especially in the gap area at the connection between the first flange pipe 2 and the second flange pipe 3, which can effectively contain leaked gas. The methane gas leaking from the second flange pipe 2 and the second flange pipe 3 quickly gathers in the concave cavity, reducing the diffusion of the leaked gas. One end of the one-way valve 202 is connected to the bellows 203, which enables one-way gas flow and ensures that the airbag 30 is sealed and stable without depressurization. One end of the bellows 203 is connected to the airbag 30. When the airbag 30 is squeezed or filled with gas, the bellows 203 can achieve flexible connection to adapt to the movement of the components. Even if there is a small amount of gas inside the bellows 203 after the airbag 30 is squeezed, it will not affect the subsequent collection.

[0042] like Figure 7 and Figure 11 As shown, the gas collection component 40 includes a gas collection tank 401 and a fixing frame 402 fixed on the surface of the gas collection tank 401. The gas collection tank 401 realizes centralized storage and recovery of leaked gas, improving energy utilization. The fixing frame 402 is fixedly connected to the sealing cover 91. The fixing frame 402 fixes the gas collection tank 401 to the sealing cover 91, so that the gas collection component 40 can move up and down synchronously with the sealing cover 91. One end of the gas collection tank 401 is provided with a gas outlet pipe 403. The gas outlet pipe 403 is provided with a valve body for opening and closing to realize the collection of gas and realize the secondary utilization of the recovered gas. The other end of the gas collection tank 401 is provided with a gas guide pipe 404, and the gas guide pipe 404 passes through and connects to one side of the sealing cover 91. The gas guide pipe 404 is connected to the air bag 30. A sealing pipe 405 is fixedly installed on the surface of the gas guide pipe 404.

[0043] like Figure 11 As shown, the sealing component 50 includes a fixed rod 501 and a strip-shaped hole 502 that penetrates the surface of the fixed rod 501. One end of the fixed rod 501 is fixedly connected to the fixed plate 6. The fixed rod 501 is slidably connected to the air guide tube 404 and the sealing tube 405. The fixed rod 501 seals the air guide tube 404 to ensure that the airbag 30 inflates normally. The strip-shaped hole 502 can be sealed and unlocked as the air guide tube 404 moves. When the sealing cover 91 needs to move the gas collection tank 401 down to the sealing position, the fixed rod 501 can seal the air guide tube 404, cut off the connection between the airbag 30 and the gas collection tank 401, and ensure that the leaked gas can all enter the airbag 30, so that the airbag 30 can inflate quickly and achieve a strong seal, avoiding gas diversion that would cause the airbag 30 to be underinflated and the seal to fail. Conversely, when the airbag 30 is squeezed, the strip-shaped hole 502 is connected to the air guide tube 404.
