Description

Technical Field

[0001] This utility model relates to the field of gas chemical industry technology, and more specifically, to a rapid response device for flammable and explosive gas leaks in mechanical workshops. Background Technology

[0002] Machine workshops are the core locations for machining, parts assembly, and equipment maintenance in industrial production. They often use cutting fluids and fuels containing volatile components and are equipped with a large number of pipelines and equipment for transporting flammable and explosive gases or liquids. When pipeline seals age and fail, equipment interfaces become loose, or operating procedures are not standardized, flammable and explosive gas leaks can easily occur. Therefore, flammable and explosive gas leak handling devices are needed to deal with them in a timely manner.

[0003] In existing technologies, some flammable and explosive gas leak handling devices have several problems during use: 1. They rely on complex electronic control and induction systems to trigger actions, resulting in significant response delays. This makes it difficult to quickly form a flow channel before the gas spreads in large quantities, leading to an expansion of the leak area. At the same time, the safety protection measures are limited and cannot adapt to leak scenarios of different intensities. 2. Most devices do not have a dedicated buffer structure. The initial impact pressure of the leaked gas acts directly on the extraction components, which can easily damage core components, increase maintenance costs, and shorten the service life of the equipment.

[0004] Therefore, there is an urgent need for a rapid response device for flammable and explosive gas leaks in mechanical workshops to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rapid response device for flammable and explosive gas leaks in mechanical workshops, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rapid response device for flammable and explosive gas leaks in a machine shop, comprising a gas collection and explosion-proof pipe, and further comprising: Multiple placement slots are provided on the inner wall of the gas collection explosion-proof pipe and are distributed circumferentially along the gas collection explosion-proof pipe. Exhaust duct A is located at the top of the gas collection explosion-proof pipe; Exhaust trough B is located at the bottom of the gas collection explosion-proof pipe, and exhaust trough B is located on the right side of exhaust trough A in the vertical direction. A return explosion-proof pipe is fixedly connected to the inner wall of exhaust trough B. Explosion-proof components include: An impact tube is slidably connected to the inner wall of a gas collection explosion-proof tube. Multiple sets of sliding rods are fixedly connected to the side wall of the impact tube and are distributed circumferentially along the impact tube. The sliding rods are slidably connected to the gas collection explosion-proof tube. A strong tension spring is sleeved on the outer wall of the slide rod, and the strong tension spring is fixedly connected between the side wall of the impact tube and the inner wall of the placement groove; Channel A is located at the top of the impact pipe; Through groove B is opened at the bottom of the impact tube, and through groove B and through groove A are symmetrically distributed about the horizontal direction of the impact tube; An air extraction assembly is disposed on the inner wall of the exhaust channel A, and the air extraction assembly cooperates with the explosion relief assembly.

[0007] As a preferred technical solution of this application, the air extraction component includes: The connecting pipe is fixedly connected to the inner wall of the exhaust trough A, and the end of the connecting pipe away from the exhaust trough A is fixedly connected to the suction pipe. The connecting pipe is fixedly connected to the return explosion-proof pipe, and the top of the suction pipe is fixedly connected to the outer connecting pipe. A drive motor is fixedly connected to the side wall of the suction pipe, and a drive rod is fixedly connected to the output end of the drive motor. A fan blade is fixedly connected to the outer wall of the drive rod, and an arc-shaped plate is also fixedly connected to the outer wall of the drive rod. An inert gas box is fixedly connected to the side wall of the extraction pipe, and the inert gas box cooperates with the arc-shaped plate.

[0008] As a preferred technical solution of this application, the sidewall of the impact tube is fixedly connected to an installation ring by multiple sets of bolts, and the bolts are distributed circumferentially along the impact tube. The sidewall of the installation ring is provided with a groove, and an explosion-proof plate is engaged between the groove and the impact tube.

[0009] As a preferred technical solution of this application, a sealing ring is sleeved on the outer wall of the impact tube, and the outer wall of the sealing ring abuts against the inner wall of the gas collection explosion-proof tube.

[0010] As a preferred technical solution of this application, a docking flange is fixedly connected to the outer wall of the gas collecting explosion-proof pipe, and the docking flange is used for the connection between the gas collecting explosion-proof pipe and the equipment.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. The design utilizes a central mechanism, a sliding rod, and a powerful tension spring to directly trigger the impact tube's action through gas pressure. This eliminates the need for complex electronic control and induction delays, allowing for rapid transition from gas leakage to the formation of a preliminary flow channel. It enables the initiation of the response process before a large amount of gas diffuses, effectively controlling the leak's extent. Simultaneously, once the extraction assembly is activated, the suction force generated by the fan blades quickly extracts gas from both the gas collection and return explosion-proof tubes, improving exhaust efficiency. Combined with the inert gas box, intermittently released inert gas from the arc-shaped plate mixes with the leaked gas, reducing the risk of gas combustion and explosion. Combined with the emergency pressure relief function of the explosion-proof plate, this design provides multiple layers of safety, adapting to various leak scenarios. It solves the problems of existing technologies that rely on complex electronic control and induction triggers, resulting in significant response delays and difficulty in quickly forming a flow channel before a large amount of gas diffuses, thus preventing the leak from expanding. 2. The design of the backflow explosion-proof pipe can buffer the initial strong impact force of the leaked gas when an explosion occurs, preventing high-pressure gas from directly impacting the extraction components and causing damage to parts such as fan blades and drive rods. This reduces mechanical wear, extends the overall service life of the device, and solves the problem in the prior art where the initial impact force of the leaked gas directly acts on the extraction components, easily damaging core components, increasing maintenance costs, and shortening equipment life.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figure 1-5 As shown in the figure, the rapid response device for flammable and explosive gas leaks in a mechanical workshop proposed in this embodiment, including the gas collection explosion-proof pipe 1, further includes: Multiple sets of placement slots 6 are opened on the inner wall of the gas collection explosion-proof pipe 1 and are distributed in a circular pattern along the gas collection explosion-proof pipe 1; The exhaust duct A10 is located at the top of the gas collection explosion-proof pipe 1; Exhaust trough B11 is located at the bottom of gas collection explosion-proof pipe 1, and exhaust trough B11 is located on the right side of exhaust trough A10 in the vertical direction. Return explosion-proof pipe 16 is fixedly connected to the inner wall of exhaust trough B11. Explosion-proof components include: The impact tube 3 is slidably connected to the inner wall of the gas collection explosion-proof tube 1. Multiple sets of sliding rods 5 are fixedly connected to the side wall of the impact tube 3 and are distributed in a circular pattern along the impact tube 3. The sliding rods 5 are slidably connected to the gas collection explosion-proof tube 1. A strong tension spring 7 is sleeved on the outer wall of the slide bar 5 and is fixedly connected between the side wall of the impact tube 3 and the inner wall of the placement groove 6. The through groove A8 is located at the top of the impact tube 3; A through-slot B9 is located at the bottom of the impact tube 3, and through-slot B9 and through-slot A8 are symmetrically distributed about the horizontal direction of the impact tube 3. As leaked gas accumulates and explodes, the internal pressure of the impact tube 3 rises rapidly. This pressure acts on the inner wall of the impact tube 3, generating a rightward thrust. When this thrust exceeds the preset tension of the strong tension spring 7, the system reaches the critical point for mode switching. Under the pressure, the impact tube 3 overcomes the spring tension and slides to the right. The slide rod 5 is guided in the placement groove 6. When the through-slot A8 at the top of the impact tube 3 is misaligned with the exhaust groove A10 at the top of the gas collection explosion-proof pipe 1, the path to the extraction pipe 18, the drive motor 19, and the drive rod 20 is automatically closed. The bottom through groove B9 is aligned with the exhaust groove B11 at the bottom of the gas collection explosion-proof pipe 1, opening the path to the return explosion-proof pipe 16. At this time, if an explosion or high-pressure impact occurs, the high-temperature and high-pressure gas will pass through the newly opened through groove B9, exhaust groove A10 and exhaust groove B11 and be quickly introduced into the dedicated return explosion-proof pipe 16, thereby preventing the high-pressure shock wave from directly impacting the precision exhaust fan blade 21 and drive motor 19, protecting the core exhaust equipment. When the internal pressure drops and the tension of the strong tension spring 7 exceeds the gas pressure's thrust on the impact pipe 3 again, the spring will pull the impact pipe 3 back to the left. After returning to the left, the through groove A8 and the exhaust groove A10 are realigned, and the exhaust channel is restored. An air extraction assembly is installed on the inner wall of the exhaust channel A10, and the air extraction assembly and the explosion relief assembly cooperate with each other.

[0016] like Figure 2 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the air extraction component further includes: The connecting pipe 17 is fixedly connected to the inner wall of the exhaust channel A10, and the end of the connecting pipe 17 away from the exhaust channel A10 is fixedly connected to the suction pipe 18. The connecting pipe 17 is fixedly connected to the return explosion-proof pipe 16, and the top of the suction pipe 18 is fixedly connected to the outer connecting pipe 23. The drive motor 19 is fixedly connected to the side wall of the suction pipe 18, and the output end of the drive motor 19 is fixedly connected to the drive rod 20. The outer wall of the drive rod 20 is fixedly connected to the fan blade 21, and the outer wall of the drive rod 20 is also fixedly connected to the arc plate 22. The inert gas box 24 is fixedly connected to the side wall of the extraction pipe 18, and the inert gas box 24 cooperates with the arc plate 22. The drive motor 19 can be triggered or automatically started, driving the fan blade 21 to rotate at high speed. The residual leaked gas in the gas collection explosion-proof pipe 1 and the flue gas that may return through the return explosion-proof pipe 16 are efficiently extracted through the connecting pipe 17 and discharged through the external connecting pipe 23. At the same time, the inert gas box 24 can be intermittently discharged through the rotating arc plate 22 and mixed with the leaked gas to reduce the probability of deflagration.

[0017] like Figure 3 As shown, in a preferred embodiment, based on the above method, the side wall of the impact tube 3 is further fixedly connected to an installation ring 12 by multiple sets of bolts 14, and the bolts 14 are distributed circumferentially along the impact tube 3. The side wall of the installation ring 12 is provided with a groove 13, and an explosion-proof plate 15 is snapped between the groove 13 and the impact tube 3. The explosion-proof plate 15 has strong explosion-proof properties. Since the impact force generated by the leaked gas directly acts on and impacts the explosion-proof plate 15, a high-strength plate with explosion-proof properties is required to adapt to the impact force generated by the explosion.

[0018] like Figure 2 As shown, in a preferred embodiment, based on the above method, a sealing ring 4 is further provided on the outer wall of the impact tube 3, and the outer wall of the sealing ring 4 abuts against the inner wall of the gas collection explosion-proof tube 1. The sealing ring 4 prevents leaked gas from entering the area where the strong tension spring 7 is located.

[0019] like Figure 1 As shown, in a preferred embodiment, based on the above method, a connecting flange 2 is fixedly connected to the outer wall of the gas collecting explosion-proof pipe 1. The connecting flange 2 is used for the connection between the gas collecting explosion-proof pipe 1 and the equipment. The device is installed at the interface of equipment or pipeline that is prone to leakage through the connecting flange 2. When a gas leak occurs, the leaked gas is first collected and enters the gas collecting explosion-proof pipe 1 and the impact pipe 3.

[0020] Specifically, in use, the rapid response device for flammable and explosive gas leaks in this mechanical workshop works as follows: The device is installed at the interface of equipment or pipeline prone to leaks via the connecting flange 2. When a gas leak occurs, the leaked gas is first collected and enters the gas collection explosion-proof pipe 1 and the impact pipe 3. As the leaked gas continues to accumulate and explodes, the pressure inside the impact pipe 3 rises rapidly. This pressure acts on the inner wall of the impact pipe 3, generating a rightward thrust. When this thrust exceeds the preset tension of the strong tension spring 7, the system reaches the critical point for mode switching. Under the pressure, the impact pipe 3 overcomes the spring tension and slides to the right. The slide rod 5 is guided in the placement groove 6. When the through groove A8 at the top of the impact pipe 3 is misaligned with the exhaust groove A10 at the top of the gas collection explosion-proof pipe 1, the path to the extraction pipe 18, drive motor 19, and drive rod 20 is automatically closed. The through groove B9 at the bottom of the impact pipe 3 is aligned with the exhaust groove B11 at the bottom of the gas collection explosion-proof pipe 1, opening the path to the return explosion-proof pipe 16. In the event of an explosion or high-pressure impact, the high-temperature and high-pressure gas will be rapidly introduced into the dedicated return explosion-proof pipe 16 through the newly opened channels B9, A10, and B11, thus preventing the high-pressure shock wave from directly impacting the precision exhaust fan blades 21 and drive motor 19, protecting the core exhaust equipment. When the internal pressure drops and the tension of the strong tension spring 7 exceeds the gas pressure's thrust on the impact pipe 3 again, the spring will pull the impact pipe 3 back to the left. After returning to its original position, the channel A8 and exhaust channel A10 will be realigned, and the exhaust channel will be restored. At the same time, the drive motor 19 can be triggered or automatically started, driving the fan blades 21 to rotate at high speed. The residual leaked gas in the gas collection explosion-proof pipe 1, as well as the flue gas that may return through the return explosion-proof pipe 16, will be efficiently extracted through the connecting pipe 17 and discharged through the external connecting pipe 23. Meanwhile, the inert gas box 24 can be intermittently discharged through the rotating arc plate 22 and mixed with the leaked gas, reducing the probability of deflagration.
