Description

Technical Field

[0001] This utility model relates to the technical field of coal mine safety extraction equipment, specifically to a device for installing a venting disc. Background Technology

[0002] The main component of coal mine gas is methane, a mixed harmful gas that emerges and is generated from coal seams, rock strata, and goafs during coal mining. Coal mine gas is flammable, and when the gas concentration reaches a certain level during extraction and utilization, it is highly susceptible to combustion or explosion when exposed to an ignition source. Therefore, when coal mine gas is transported via pipeline, the pipeline needs to be equipped with a water-sealed flame arrestor and explosion venting device (explosion venting device). However, in actual on-site installation, the explosion venting disc is often directly installed on the water-sealed flame arrestor and explosion venting device, and then the detonating cord is directly installed.

[0003] For example, Chinese utility model patent CN221974404U discloses a drawer-type explosion relief disc installation device, including a water-sealed flame arrestor explosion relief device and an explosion relief disc body. A horizontal gas conveying pipe is provided in the middle of one side surface of the water-sealed flame arrestor explosion relief device, and an equal-diameter connecting pipe is provided on the top surface of the explosion relief outlet. An explosion relief disc installation box is provided on the top surface of the equal-diameter connecting pipe, and the explosion relief disc body is provided inside the explosion relief disc installation box. A pressure ring is provided on the outer ring of one side surface of the explosion relief disc body, and a sealing sheet is provided on one side surface of the pressure ring. By adopting a drawer-type installation method for the explosion relief disc, the explosion relief disc can be easily replaced on-site in a short time, avoiding secondary disasters caused by prolonged shutdown of the gas drainage pumping station. At the same time, the drawer-type explosion relief disc installation device can bear the weight of the detonating tube to a certain extent, without the need for an auxiliary steel platform, saving installation costs and installation space, and ensuring the stable operation of the gas drainage pumping station.

[0004] Because the explosion relief disc deforms and becomes taller when it is punctured, and the explosion relief disc mounting box used in the aforementioned patent is very low, it is difficult to remove and replace the damaged explosion relief disc from the side of the mounting box, making it inconvenient to disassemble and replace the damaged explosion relief disc.

[0005] To address the aforementioned issues, innovative designs were developed based on the existing framework. Utility Model Content

[0006] The purpose of this utility model is to provide a device for installing a venting disc to solve at least one of the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detonation relief device, comprising: a water-sealed flame arrestor and detonation relief device, wherein a horizontal gas conveying pipe is provided in the middle of the water-sealed flame arrestor and detonation relief device, and a detonation relief outlet is provided at the top of the water-sealed flame arrestor and detonation relief device, wherein the outer side of the detonation relief outlet is fixedly connected to the outer side of the detonating tube through a connecting plate. The inner top of the explosion relief outlet is provided with an installation groove, and an explosion relief disc is engaged inside the installation groove; The detonating cord has a movable tube inside, the lower end of which abuts against the top of the detonating disc. When the movable tube moves upward to its highest point, the distance between the lower end of the movable tube and the top of the detonating disc is greater than the diameter of the detonating disc. The connecting plate is provided with a limiting mechanism for fixing the movable tube.

[0008] Preferably, the limiting mechanism includes a slot, the lower outer side of the fixed movable tube is provided with a slot, a locking plate is engaged inside the slot, a lead screw is rotatably installed in the middle of the locking plate through a sealed bearing, the outer side of the lead screw is threadedly connected to the inner side of the connecting plate, a limiting rod is fixed on the outer side of the locking plate, and the limiting rod is slidably connected to the connecting plate.

[0009] Preferably, the end of the lead screw is fixed with a handle that passes through the interior of the connecting plate, and the handle is shaped like a plum blossom.

[0010] Preferably, there are two limiting rods, which are symmetrically distributed about the central axis of the card plate.

[0011] Preferably, the slot is configured as a ring structure, the card plate is configured as an arc-shaped structure, the outer side of the card plate is in contact with the inner side of the slot, and two card plates are symmetrically distributed about the central axis of the movable tube.

[0012] Preferably, the top of the explosion relief disc is fixed with a handle, and the handle is configured as a "T" shape.

[0013] Preferably, a high-temperature resistant fluororubber ring is fixed to the top of the explosion relief outlet, and the top of the high-temperature resistant fluororubber ring abuts against the lower end of the movable tube.

[0014] Preferably, a second high-temperature resistant fluororubber ring is fixed to the inner side of the detonating cord, and the inner side of the second high-temperature resistant fluororubber ring abuts against the outer side of the movable tube.

[0015] Preferably, there are two connecting plates symmetrically distributed about the central axis of the detonating cord, and a reinforcing block is fixed at the inner corner of the connecting plate.

[0016] Preferably, a lifting rod is fixed to the outer wall of the movable tube near the slot.

[0017] The explosion relief disc installation device of this utility model has the following beneficial effects: By rotating the handle forward or backward, the clamping plate can be moved left or right, allowing it to quickly separate or engage with the slot. This facilitates the rapid fixing or detachment of the movable tube. The lifting rod can be used to move the movable tube upward, exposing the damaged explosion vent, thus facilitating its quick removal. Because the distance between the lower end of the movable tube and the top of the explosion vent is greater than the diameter of the explosion vent when the movable tube is moved to its highest point, it ensures that the movable tube will not interfere with the removal and replacement of the deformed and heightened explosion vent from the top of the explosion vent outlet.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a detonator installation device, including: a water-sealed fire-arresting detonator 1, a horizontal gas conveying pipe 2 in the middle of the water-sealed fire-arresting detonator 1, a detonation outlet 3 at the top of the water-sealed fire-arresting detonator 1, and the outer side of the detonation outlet 3 being fixedly connected to the outer side of the detonating tube 5 through a connecting plate 4. An installation groove 6 is provided on the inner top of the explosion vent 3. An explosion vent 7 is engaged inside the installation groove 6. A high-temperature resistant fluororubber ring 3 is fixed at the bottom of the installation groove 6. The top of the high-temperature resistant fluororubber ring 3 abuts against the bottom of the explosion vent 7. The detonating cord 5 has a movable tube 8 inside. The lower end of the movable tube 8 abuts against the top of the detonating disc 7. When the movable tube 8 moves upward to the highest point, the distance between the lower end of the movable tube 8 and the top of the detonating disc 7 is greater than the diameter of the detonating disc 7. The connecting plate 4 is provided with a limiting mechanism for fixing the movable tube 8.

[0027] The limiting mechanism in this example includes a slot 9. A slot 9 is provided on the outer side of the lower end of the fixed movable tube 8. A locking plate 10 is engaged inside the slot 9. A lead screw 11 is rotatably mounted on the middle of the locking plate 10 through a sealed bearing. The outer side of the lead screw 11 is threadedly connected to the inner side of the connecting plate 4. A limiting rod 12 is fixed on the outer side of the locking plate 10. The limiting rod 12 is slidably connected to the connecting plate 4. The lead screw 11 is made of 316 stainless steel. The surface of the lead screw 11 is passivated to form an oxide protective film. By rotating the lead screw 11, the lead screw 11 can drive the locking plate 10 to move to the left or right, so that the locking plate 10 can engage or disengage from the slot 9, thereby facilitating the quick fixing or disassembly of the movable tube 8.

[0028] In this example, the end of the lead screw 11 is fixed with a handle 13 through the inside of the connecting plate 4. The handle 13 is set in a plum blossom shape, which facilitates the rotation of the lead screw 11.

[0029] In this example, there are two limit rods 12. The two limit rods 12 are symmetrically distributed about the central axis of the clamping plate 10, which increases the stability of the horizontal movement of the clamping plate 10.

[0030] In this example, the slot 9 is set as a ring structure, and the card plate 10 is set as an arc structure. The outer side of the card plate 10 fits into the inner side of the slot 9. There are two card plates 10 symmetrically distributed about the central axis of the movable tube 8, which increases the contact surface between the card plate 10 and the movable tube 8 and improves the stability of the movable tube 8.

[0031] In this example, the top of the explosion relief disc 7 is fixed with a handle 14. The handle 14 is set with a "T" shape, which makes it easy to pick up the explosion relief disc 7 and place it inside the mounting slot 6.

[0032] In this example, the top of the explosion vent 3 is fixed with a high-temperature resistant fluororubber ring-15. The top of the high-temperature resistant fluororubber ring-15 abuts against the lower end of the movable tube 8, which increases the sealing of the connection between the explosion vent 3 and the movable tube 8.

[0033] In this example, a high-temperature resistant fluororubber ring 16 is fixed to the inner side of the detonating cord 5. The inner side of the high-temperature resistant fluororubber ring 16 abuts against the outer side of the movable tube 8, which increases the sealing at the connection between the detonating cord 5 and the movable tube 8. Furthermore, the friction between the movable tube 8 and the high-temperature resistant fluororubber ring 16 is greater than the weight of the movable tube 8, so that the movable tube 8 can be fixed after moving on the detonating cord 5, making it convenient to remove the damaged explosion relief disc 7 from the explosion relief outlet 3.

[0034] In this example, there are two connecting plates 4 symmetrically distributed about the central axis of the detonating cord 5. A reinforcing block 17 is fixed at the inner corner of the connecting plate 4. The setting of the connecting plate 4 allows the detonating cord 5 and the explosion relief outlet 3 to be fixed together without the need for an additional bracket to fix the detonating cord 5.

[0035] In this example, a lifting rod 18 is fixed to the outer wall of the movable tube 8 near the slot 9, which facilitates the up and down movement of the movable tube 8.

[0036] Working principle: When a gas explosion occurs during gas extraction, the resulting high pressure will rupture the explosion relief disc 7. The pressure, flame, and some gas generated by the explosion will be diverted to a safe area through the movable pipe 8 and the detonating pipe 5. When it is necessary to remove the damaged explosion relief disc 7 from the inside of the explosion relief outlet 3, rotate the handle 13. The handle 13 drives the lead screw 11 to rotate. Since the lead screw 11 is threadedly connected to the connecting plate 4, and the middle of the clamping plate 10 is rotatably mounted with the lead screw 11 through a sealed bearing, and the limiting rod 12 is slidably connected to the connecting plate 4, the lead screw 11 drives the clamping plate 10 to separate from the clamping groove 9. Similarly, rotate the other handle 13 to separate the other clamping plate 10 from the other clamping groove 9. At this time, the movable tube 8 is disengaged from the fixed position. Then, push the movable tube 8 upward through the lifting rod 18 until the top of the lifting rod 18 touches the bottom of the detonating tube 5. At this time, the movable tube 8 moves to the highest position, ensuring that the movable tube 8 will not affect the removal of the deformed and raised explosion relief disc 7 from the top of the explosion relief outlet 3. Remove the deformed, heightened explosion vent 7 from the mounting slot 6. Pick up the new explosion vent 7 using the handle 14 and secure it inside the mounting slot 6. Then, move the movable tube 8 downwards until its lower end contacts the top of the explosion vent 7. At this point, the locking plate 10 aligns with the locking slot 9. Then, following the same procedure, rotate the handle 13 to engage the locking plate 10 with the locking slot 9, thus quickly securing the movable tube 8 and the explosion vent 7. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
