Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline settlement detection, in particular to a gas pipeline settlement detection device. Background Art

[0002] The main causes of gas pipeline settlement include foundation settlement and geological settlement. Foundation settlement is one of the main causes of gas pipeline settlement. Foundation settlement usually occurs during the consolidation and compaction process of fill, causing damage to gas pipelines. Geological settlement is another cause of gas pipeline settlement. Geological settlement can be caused by natural factors such as loose soil and slow settlement due to its own gravity, or by human factors such as construction and over-exploitation. Gas pipeline settlement caused by such factors can cause fractures in the connection areas of the gas pipeline, causing gas leakage and posing a major safety hazard. Therefore, such gas pipeline settlement detection devices play a very important role in the daily deployment of gas pipelines.

[0003] The existing gas pipeline settlement detection device is equipped with a settlement and downward safety alarm structure on the top, which will sound an alarm in case of settlement. Therefore, this type of structure is usually installed underground together with the gas pipeline, or hidden behind a cabinet to prevent the alarm structure from being accidentally triggered in daily life. However, this concealed installation makes it difficult for staff to find the pipeline in the corresponding alarm area and take protective measures in the first time when the gas pipeline settles. In this regard, this design proposes a gas pipeline settlement detection device. Utility Model Content

[0004] The purpose of this utility model is to provide a gas pipeline settlement detection device to solve the problems raised in the above-mentioned background technology. To achieve the above-mentioned purpose, the utility model proposes a gas pipeline settlement detection device, comprising a mounting plate, detection alarm mechanisms and connection components, both mounted on the front of the mounting plate in upper and lower distributions;

[0005] The detection alarm mechanism includes limiting slide grooves opened on both sides of the front of the mounting plate, a U-shaped connecting frame is slidably connected between the inner walls of the two limiting slide grooves, connecting rods are installed on both sides of the top of the U-shaped connecting frame, and protective sleeves are installed at the bottom of the inner walls of the two limiting slide grooves. Support rods are connected to the inner walls of the two protective sleeves on both sides of the bottom of the mounting plate, and the tops of the two support rods are respectively installed with first contact blocks, and the tops of the two first contact blocks are installed with pressure sensors, and the bottoms of the two connecting rods are connected to the second contact blocks through the inner walls of the protective sleeves.

[0006] In one example, springs are sleeved on the outer walls of one end of the two support rods, and one end of the two springs is fixedly connected to the bottom of the two first contact blocks respectively.

[0007] In one example, an alarm is installed on one side of the front of the mounting plate, and the alarm is electrically connected to the two pressure sensors respectively.

[0008] In one example, a pointer is fixedly provided at the middle position of the top of the U-shaped connecting frame, and a scale line is engraved at the middle position of the front side of the mounting plate.

[0009] In one example, the connecting assembly includes a fixed rod fixed at the middle position of the bottom of the U-shaped connecting frame, a fixed clamp is fixed at the bottom of the fixed rod, one end of the fixed clamp is hinged with a movable clamp, and one end of the fixed clamp is threadedly connected to one end of the movable clamp by a bolt.

[0010] Compared with the prior art, the beneficial effect of the present invention is: by setting up a detection alarm mechanism, while detecting the settlement of the gas pipeline, the U-shaped connecting frame slides down to make it carry the second contact block in contact and squeeze with the first contact block in the protective sleeve, so that the two pressure sensors simultaneously issue instructions and the alarm sounds an alarm. In this process, a series of processes of settlement contact triggering an alarm are all carried out in the protective sleeve, so that even if the detection device is installed in an exposed external field, it is not easy to be accidentally touched to cause the alarm to sound, and there is no need for hidden installation. This solves the problem in the prior art that the settlement detection device is installed in the outside world and is easily accidentally touched and needs to be hidden.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-4 The utility model provides a technical solution: a gas pipeline settlement detection device, comprising a mounting plate 1, a detection alarm mechanism 2 and a connecting component 5, both of which are mounted on the front of the mounting plate 1 and distributed in the upper and lower directions;

[0018] The feature is that the detection alarm mechanism 2 includes limiting slide grooves 201 provided on both sides of the front face of the mounting plate 1, a U-shaped connecting frame 202 is slidably connected between the inner walls of the two limiting slide grooves 201, connecting rods 203 are installed on both sides of the top of the U-shaped connecting frame 202, protective sleeves 204 are installed on the bottom of the inner walls of the two limiting slide grooves 201, support rods 205 are connected through the inner walls of the two protective sleeves 204 on both sides of the bottom of the mounting plate 1, first contact blocks 206 are installed on the tops of the two support rods 205, pressure sensors 207 are installed on the tops of the two first contact blocks 206, and the bottoms of the two connecting rods 203 are connected to the second contact blocks 208 through the inner walls of the protective sleeves 204.

[0019] When in use, the detection alarm mechanism 2 on the mounting plate 1 is connected to the gas pipeline through the connecting component 5. After the connection, the U-shaped connecting frame 202 stays in the limiting slide 201 under the support of the connecting fixing rod 501 and does not move up and down. At this time, the second contact block 208 connected to the bottom of the U-shaped connecting frame 202 through the connecting rod 203 does not contact the pressure sensor 207 on the first contact block 206. Once the gas pipeline is raised or lowered, the connecting component 5 will slide down in the limiting slide 201 with the U-shaped connecting frame 202. At this time, the connecting rod 203 and the second contact block 208 will descend and squeeze the pressure sensor 207 on the first contact block 206, and at this time, both pressure sensors 207 are squeezed. The second contact block 208 slides downward and contacts and squeezes the first contact block 206 with the second contact block 208, so that the detection device can be installed in the external environment of the gas pipeline installation area through the mounting plate 1. After the alarm 210 sounds an alarm, the staff does not need to look for the alarm source underground or behind the cabinet. Moreover, since the contact areas are arranged on the inner side of the protective sleeve 204 when the alarm is exposed to the external environment for a long time, it is not easy to be accidentally triggered. The device can be directly exposed for use, which solves the problem in the prior art that the gas pipeline settlement detection device is easily accidentally touched when installed in the outside world and the alarm sound source is difficult to be found when it is concealed.

[0020] Furthermore, the outer walls of one end of the two support rods 205 are each sleeved with a spring 209, and one end of the two springs 209 is fixedly connected to the bottom of the two first contact blocks 206 respectively, and when the first contact block 206 is not in contact with the second contact block 208, the first contact block 206 supports the support rod 205 through the spring 209 and then supports the first contact block 206 and the pressure sensor 207 at its upper end at a specified height, so that when the pipeline sinks later, it can quickly contact the second contact block 208 to alarm.

[0021] An alarm 210 is installed on one side of the front of the mounting plate 1, and the alarm 210 is electrically connected to the two pressure sensors 207. Therefore, the alarm can only be sounded when both pressure sensors 207 are squeezed at the same time, preventing the alarm 210 from sounding when a single pressure sensor 207 is accidentally touched.

[0022] Furthermore, a pointer 3 is fixed in the middle position of the top of the U-shaped connecting frame 202, and a scale line 4 is engraved in the middle position of the front of the mounting plate 1. When the gas pipeline sinks, the connecting assembly 5 descends with the U-shaped connecting frame 202. At this time, the scale data indicated by the pointer 3 on the scale line 4 changes, and the staff can judge the settlement height at the first time and take corresponding measures.

[0023] Furthermore, the connecting component 5 includes a fixed rod 501 fixed in the middle position of the bottom of the U-shaped connecting frame 202, and a fixed clamp 502 is fixed at the bottom of the fixed rod 501, and one end of the fixed clamp 502 is hinged with a movable clamp 503, and one end of the fixed clamp 502 is threadedly connected to one end of the movable clamp 503 by a bolt. The fixed clamp 502 and the movable clamp 503 are mutually locked and sleeved on the outside of the gas pipeline, and then threadedly fixed with bolts, and connected to the U-shaped connecting frame 202 through the fixed rod 501. The entire detection device is in a tightened state. Once the connecting component 5 sinks with the gas pipeline, the interface of the U-shaped connecting frame 202 slides down together, thereby triggering an alarm.
