The main task of gas engineering construction is to provide users with safe and reliable gas services in a safe, efficient, environmentally friendly and energy-saving manner. Gas pipelines are an important part of gas engineering. Generally, the joints of gas pipelines need to be protected by safety protection devices.

[0003] After searching, the Chinese patent announcement number: CN219933742U discloses a gas engineering safety protection device. Through the cooperation of the pressure detection mechanism, the extrusion mechanism and the alarm mechanism, when a leak occurs at the connection of the gas pipeline, an alarm will be sounded in time to remind personnel, so that personnel can know and deal with it in time. In addition, combined with the sealing and shielding protection of the gas pipeline, it can effectively prevent gas leakage to the outside, further improving the protection effect.

[0004] In the above technical solution, pressure detection is used in conjunction with an alarm mechanism to alarm the staff when a gas pipeline leaks. However, in gas engineering, the laying area of ​​the gas pipeline is large and the range is wide. When the alarm is triggered after a gas leak, the staff cannot immediately find the leakage location, thereby reducing the protection effect. Therefore, a gas engineering safety protection device is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a gas engineering safety protection device, which aims to improve the problem that the gas engineering safety protection device in the prior art lacks an alarm when the gas pipeline leaks so that the staff can find the leakage location, resulting in reduced protection effect.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a gas engineering safety protection device, comprising a lower fixed block, an upper fixed block is arranged on the top of the lower fixed block, a protection structure is arranged on the surface of the lower fixed block, the protection structure comprises a fixed plate, the inner wall of the fixed plate is threadedly connected with a threaded rod, the inner wall of the fixed plate is slidably connected with a limiting rod, an installation groove is opened on the inner surface of the lower fixed block, a buffer assembly is arranged inside the installation groove, an auxiliary assembly is arranged on the surface of the lower fixed block, and an alarm assembly is arranged on the top of the upper fixed block.

[0023] 2. In the utility model, the two groups of upper fixed blocks are positioned by providing a snap-fit ​​block, and the squeeze snap can be separated from the block by the elastic force of the fixing spring, thereby reducing the impact of gas leakage on the upper fixed block and improving the engagement between the two groups of fixed blocks.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a gas engineering safety protection device, comprising a lower fixed block 1, an upper fixed block 2 is arranged on the top of the lower fixed block 1, the lower fixed block 1 and the upper fixed block 2 are each provided with two groups, and the two groups of lower fixed blocks 1 and the upper fixed block 2 are arranged in a mirror image, and a protective structure is arranged on the surface of the lower fixed block 1, and the protective structure includes a fixed plate 3, the inner wall of the fixed plate 3 is threadedly connected with a threaded rod 4, and the inner wall of the fixed plate 3 is slidably connected with a limit rod 5, and the fixed plates 3 are respectively arranged in groups of two and distributed on the outer walls of the upper fixed block 2 and the lower fixed block 1, and the fixed plates 3 in groups of two are used to install the threaded rod 4 and the limit rod 5, the inner surface of the lower fixed block 1 is provided with an installation groove 6, and a buffer component is arranged inside the installation groove 6, the surface of the lower fixed block 1 is provided with an auxiliary component, and the top of the upper fixed block 2 is provided with an alarm component.

[0032] Reference Figure 2-Figure 4 The buffer component includes a telescopic rod 7, and the outer wall of the telescopic rod 7 is provided with a telescopic spring 8. The elastic properties of the telescopic rod 7 and the telescopic spring 8 can enable the airbag 9 to maintain a closed contact with the gas pipeline. The end of the telescopic spring 8 is fixedly connected to the airbag 9. The airbag 9 is made of rubber material and has a certain friction when it fits with the pipe wall of the gas pipeline. The auxiliary component includes an air inlet 10. The inner wall of the airbag 9 is fixedly connected to a transmission pipe 11. The outer wall of the transmission pipe 11 is fixedly connected to a mounting frame 12. The transmission pipe 11 is made of a telescopic hose material and can be telescopically deformed when the distance between the lower fixed block 1 and the upper fixed block 2 changes, thereby ensuring that the leaked gas is transmitted to the mounting frame 12. A floating ball 13 is arranged inside the mounting frame 12, and the floating ball 13 is transmitted through the transmission pipe 11. The gas entering the airbag 9 blows until the float 13 squeezes the push switch 14. The inner wall of the mounting frame 12 is fixedly connected with the push switch 14. After the switch end of the push switch 14 is subjected to force, the buzzer 15 and the warning light 16 are started. The buzzer 15 and the warning light 16 are electrically connected to the external battery through wires respectively. The battery provides power supply for the buzzer 15 and the warning light 16. The alarm component includes the buzzer 15, and the warning light 16 is fixedly connected to the top of the upper fixed block 2. The outer wall of the telescopic rod 7 is fixedly connected to the inner wall of the mounting groove 6, and the outer wall of the buzzer 15 is fixedly connected to the upper surface of the upper fixed block 2. The buzzer 15 generates a buzzing sound after being turned on, and the warning light 16 flashes after being turned on, which can facilitate the staff to confirm which group of gas pipeline connections has a leak.

[0033] Reference Figure 2-Figure 4 A groove 17 is provided on the outer wall of the upper fixed block 2, a fixing spring 18 is fixedly connected to the inner wall of the groove 17, a buckle 19 is fixedly connected to the end of the fixing spring 18, a block 20 is engaged with the outer wall of the buckle 19, and the outer wall of the block 20 is matched with the inner surface of the buckle 19. When the buckle 19 is inserted into the groove 17 for installing the block 20, the degree of engagement of the two sets of upper fixed blocks 2 can be increased.

[0034] Working principle: The two groups of lower fixed blocks 1 and upper fixed blocks 2 support the connection of the gas pipeline. By rotating the threaded rod 4 forward or reversely and then limiting the position of the limit rod 5, the distance between the upper fixed block 2 and the lower fixed block 1 can be adjusted until each group of air bags 9 fits the outer wall of the gas pipeline. At this time, due to the elastic force of the telescopic rod 7 and the telescopic spring 8, the air bag 9 is close to the connection of the gas pipeline. As the two groups of upper fixed blocks 2 approach, the buckle 19 is inserted into the second group of grooves 17 and connected to the block 20. When a leak occurs at the connection of the gas pipeline, due to the setting of the air inlet hole 10, the gas will enter the inside of the air bag 9, and then enter the inside of the installation frame 12 through the transmission pipe 11. The float 13 is driven by the entering gas to gradually rise inside the installation frame 12 until the float 13 squeezes the press switch 14. The press switch 14 controls the opening of the buzzer 15 and the warning light 16 to warn the maintenance personnel, so that the maintenance personnel can immediately confirm the leakage location and improve the protection effect of the gas project.
