Description

Technical Field

[0001] The utility model relates to the technical field of gas alarm equipment, in particular to a disconnection alarm device. Background Art

[0002] Natural gas pipelines are usually buried underground, but sometimes they are easily damaged during mining or construction. Therefore, some people set up alarm posts near the natural gas pipelines to serve as a warning.

[0003] The prior art with announcement number CN214067934U discloses a warning pile applied to a gas pipeline, including a pile body, the pile body is divided into an above-ground part and an underground part by a sleeved guard plate, a warning light is arranged on the side of the above-ground part of the pile body, a disconnection alarm is arranged in the pile body, and the signal line of the disconnection alarm is arranged in the underground part of the pile body near the guard plate and connected to another pile body. The utility model is cleverly designed. When the sight condition is not good, the warning light has a strong penetrating power and can effectively play a warning role. At the same time, the signal line of the disconnection alarm is close to the surface. When the construction personnel fail to notice and damage the signal line, the disconnection alarm will sound an alarm to prevent further digging and damage to the gas pipeline.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In order to solve the technical problem that after the signal line under the warning pile of the gas pipeline is dug up, reconnection is prone to false alarms and is time-consuming and labor-intensive, the utility model provides a disconnection alarm device, which can achieve simple and rapid reconnection through magnetic adsorption after the signal line triggers the alarm, is easy to operate, and saves time and effort.

[0024] It should be noted that the disconnection alarm device described in the utility model is used for but not limited to early warning of gas pipelines. For the convenience of explanation, in the utility model, only the application of the disconnection alarm device to early warning of gas pipelines is used as an example for explanation, and the principle of applying the disconnection alarm device to other types of equipment is essentially the same as the principle applied to gas pipeline early warning, which will not be described in detail here.

[0025] See also Figure 1 , Figure 1The schematic diagram of the structure of the disconnection alarm device in one embodiment of the utility model is as follows. The disconnection alarm device includes an alarm component 1 and a trigger component 2. The alarm component 1 includes an early warning post 11, an alarm 12, a controller 13, a first signal line 14 and a second signal line 15. The alarm 12 and the controller 13 are both arranged on the early warning post 11. One end of the first signal line 14 is connected to the alarm 12, and one end of the second signal line 15 is connected to the controller 13. The trigger component 2 includes a first connector 21 and a second connector 22. The first connector 21 is connected to the first signal line 14, specifically to the end of the first signal line 14 away from the alarm 12. The second connector 22 is connected to the second signal line 15, specifically to the end of the second signal line 15 away from the controller 13. The first connector 21 is magnetically connected to the second connector 22. When the first connector 21 is separated from the second connector 22, the controller 13 controls the alarm 12 to send out an alarm signal. In this embodiment, at least one of the first signal line 14 and the second signal line 15 is buried in the soil. When the construction workers use a tool such as a hoe to dig the soil, the hoe touches the first signal line 14 and / or the second signal line 15, driving the first connector 21 to separate from the second connector 22. The signal line can be covered with a protective tube so that the signal line can be protected and not easily cut by the hoe. When the hoe applies force to the signal line, the first connector 21 can be separated from the second connector 22.

[0026] In one embodiment, see Figure 2 The first connecting member 21 has a first magnetic member 211, and the second connecting member 22 has a second magnetic member 221. When the first connecting member 21 is close to the second connecting member 22, the first magnetic member 211 and the second magnetic member 221 are magnetically attracted to each other, so that the first connecting member 21 is connected to the second connecting member 22. At this time, the controller 13 controls the alarm 12 not to issue an alarm signal.

[0027] In one embodiment, see Figure 2 , the first connecting member 21 has a first magnetic member 211, the second connecting member 22 has a metal block, and the metal block is magnetically attracted to the first magnetic member 211; or the second connecting member 22 has a second magnetic member 221, the first connecting member 21 has a metal block, and the metal block is magnetically attracted to the second magnetic member 221. It can be seen that only one of the first connecting member 21 and the second connecting member 22 needs to be provided with a magnetic member to achieve magnetic attraction.

[0028] In one embodiment, see Figure 2The first connecting member 21 includes a first insulator 212 and a first electrode member 213. The first insulator 212 has a first mounting groove (not clearly shown in the figure). The first electrode member 213 is arranged in the first mounting groove. The first electrode member 213 is connected to the first signal line 14. The first magnetic member 211 is embedded in the end of the first insulator 212 close to the second connecting member 22, so that the first magnetic member 211 can be as close to the second magnetic member 221 as possible to generate a larger adsorption force. In this embodiment, there are two first magnetic members 211, which are respectively arranged on the upper and lower sides of the first mounting groove. The two first magnetic members 211 can magnetically adsorb the second connecting member 22 at the same time to form a more stable connection, which is not easy to be triggered by mistake. The first electrode member 213 and the first magnetic member 211 are both located inside the first insulator 212, which can save space.

[0029] In one embodiment, see Figure 2 , the second connecting member 22 includes a second insulator 222 and a second electrode member 223, and the second magnetic member 221 is embedded in the second insulator 222, specifically embedded in the end of the second insulator 222 close to the first connecting member 21, so that the second magnetic member 221 can be as close to the first magnetic member 211 as possible to generate a larger adsorption force. The second magnetic member 221 can be magnetically adsorbed with the first magnetic member 211 to drive the first electrode member 213 to be electrically connected with the second electrode member 223. At this time, the controller 13 generates a closing signal and does not control the alarm 12 to send an alarm signal. When the first electrode member 213 is disconnected from the second electrode member 223, the controller 13 generates a disconnection signal to control the alarm 12 to send an alarm signal.

[0030] In one embodiment, see Figure 2 The second insulator 222 is provided with a second mounting groove 224, and the second connecting member 22 further includes a return spring 225 disposed in the second mounting groove 224, and the return spring 225 connects the second insulator 222 and the second electrode member 223. When the first electrode member 213 is electrically connected to the second electrode member 223, the second electrode member 223 drives the return spring 225 to accumulate elastic force. Specifically, the first electrode member 213 presses the second electrode member 223, driving the second electrode member 223 to move toward the return spring 225 in the second mounting groove 224, thereby compressing the return spring 225 to accumulate elastic force.

[0031] In one embodiment, see Figure 2The first insulator 212 is provided with a first wire hole 214 connected to the first mounting slot, the second insulator 222 is provided with a second wire hole 226 connected to the second mounting slot 224, the first signal line 14 passes through the first wire hole 214 and is connected to the first electrode member 213, and the second signal line 15 passes through the second wire hole 226 and is connected to the second electrode member 223. When the first signal line 14 is pulled by an external force, the first signal line 14 drives the entire first connecting member 21 to move. When the second signal line 15 is pulled by an external force, the second signal line 15 drives the entire second connecting member 22 to move, so as to separate from the first connecting member 21.

[0032] In one embodiment, see Figure 2 The first electrode member 213 is provided with a ball groove 215, and the second electrode member 223 is a metal ball. When the first insulator 212 is connected to the second insulator 222, the metal ball is attached to the arc surface of the ball groove 215, so that the contact area between the metal ball and the ball groove 215 is large and the electrical connection is more stable.

[0033] In one embodiment, see Figure 2 The alarm assembly 1 further includes a solar panel 16 and a battery 17 connected to each other. The solar panel 16 is arranged on the top of the early warning pile 11. The battery 17 is connected to the controller 13 and the alarm 12 to supply power to the controller 13 and the alarm 12. The solar panel 16 can convert solar energy into electrical energy and store it in the battery 17.

[0034] In one embodiment, see Figure 2 The alarm 12 is an audible and visual alarm. The alarm signal emitted by the alarm 12 is a buzzer sound and a flashing light. The dual alarm of sound and light can improve the warning effect.

[0035] It should be emphasized that the first connector 21 and the second connector 22 can be both arranged inside the early warning pile 11, so that it is more convenient to reconnect the first connector 21 and the second connector 22 after disconnection. The signal line can be buried in the soil 3, arranged along the length direction of the gas pipeline, and arranged directly above the gas pipeline, so that it is easy to touch the signal line during construction above the gas pipeline, thereby driving the alarm 12 to send out an alarm signal. In addition, the signal line can be arranged between the two early warning piles 11, and controllers are arranged inside the two early warning piles 11. The two ends of the signal line are respectively connected to the two controllers. When the signal line is disconnected, the controllers can generate control signals and control the alarm 12 to send out an alarm signal. In other embodiments, the signal line can also cover between the two early warning piles 11, and only one of the early warning piles 11 is connected. When the signal line is disconnected, the controller inside the early warning pile 11 can generate a control signal to control the alarm 12 to send out an alarm signal.

[0036] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0037] When the first signal line 14 or the second signal line 15 is accidentally dug during the construction process, the force acting on the signal line can overcome the magnetic attraction force between the first connector 21 and the second connector 22, so that the first connector 21 is separated from the second connector 22, and the controller 13 controls the alarm 12 to send an alarm signal to remind the construction personnel that there is a gas pipeline here. When the signal line needs to be reconnected, it is only necessary to bring the first connector 21 and the second connector 22 closer to each other to reconnect them together by magnetic attraction, which is simple to operate and saves time and effort.

[0038] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
