Description

Technical Field

[0001] This utility model relates to the field of gas safety detection technology, and in particular to a gas safety detection device. Background Technology

[0002] Gas fuels are a general term for gaseous fuels that burn to release heat, providing fuel for urban residents and industrial enterprises. There are many types of gas fuels, mainly including natural gas, manufactured gas, liquefied petroleum gas (LPG), biogas, and coal gas. With the continuous development of science and technology, the application of gas fuels in urban residents and industrial enterprises is becoming increasingly widespread. When gas fuel mixes with air and reaches a certain concentration, it will explode upon contact with an open flame. This concentration range is called the explosion limit. To prevent gas leaks and potential hazards, gas safety detection devices are generally installed inside spaces where gas is used to monitor the gas concentration in real time and prevent accidents caused by the gas reaching the explosion limit.

[0003] Chinese utility model patent CN221667775U discloses a gas safety detection device, including a support plate. A mounting box is fixedly connected to one end of the support plate. A side groove is formed at the center of the end of the mounting box away from the support plate. A connecting plate is symmetrically and slidably connected to the side groove near its center. A detection box is fixedly connected to one end of the support plate near the mounting box. A connecting seat is fixedly connected to the end of the connecting plate away from the support plate. Two clamps are symmetrically and detachably bolted to opposite ends of the connecting seats. The sliding of the two connecting plates causes the two clamps to slide, bringing them into contact with the gas pipeline and fixing the device to the pipeline. The connecting seats and clamps are detachably connected to facilitate the removal and replacement of the clamps to adapt to different sizes of gas pipelines.

[0004] Regarding the aforementioned technologies, the inventors believe they have the following drawbacks: When fixing to gas pipelines of different sizes, the aforementioned devices require removing screws to replace the clamps to prevent excessively large clamps from having only two small contact points with the pipeline, resulting in unstable fixing. However, using the method of removing screws to replace clamps is cumbersome, as it requires carrying multiple clamps and removing screws to replace them when inspecting pipeline systems composed of pipelines of various sizes. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a gas safety detection device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gas safety detection device, including a support plate, a detection device is provided on the support plate, a fixed base is provided on the support plate, two sliding blocks are slidably arranged on the fixed base, a driving component is provided on the fixed base to drive the two sliding blocks to slide synchronously in opposite directions, a moving plate is horizontally arranged on the sliding block, a clamping plate is provided on each adjacent side of the two moving plates, two sliders are slidably arranged on the moving plate, a sliding component is provided on the moving plate to drive the two sliders to slide synchronously in opposite directions, a mounting block is provided on each adjacent side of the sliders on the two moving plates, and a clamping column is provided on the mounting block.

[0007] By adopting the above technical solution, a support plate, a fixed base, a drive assembly, a moving plate, a sliding assembly, clamping plates, and clamping columns are set up. The drive assembly drives two sliding blocks to slide synchronously towards the center of the fixed base, causing the two moving plates to move in the same way, so that the two clamping plates clamp the gas pipeline. Then, the sliding assembly drives two sliders on the corresponding moving plates to slide towards the clamping plates. The sliding of the sliders causes the mounting blocks and clamping columns to slide until the clamping columns contact the gas pipeline and clamp it. Subsequently, the detection equipment monitors the gas concentration in real time. At this time, the two clamping plates and four clamping columns clamp the pipeline, ensuring that the fixed base and support plate are stably fixed, and there is no need to change parts according to the pipeline size, making the operation convenient.

[0008] Furthermore, the movable plate has a strip-shaped hole, and the slider is slidably connected to the strip-shaped hole.

[0009] By adopting the above technical solution, a strip hole is opened on the moving plate to ensure the stability of the slider's sliding.

[0010] Furthermore, the sliding assembly includes two spaced vertical plates disposed on the side of the moving plate away from the other moving plate, a first bidirectional threaded rod rotatably disposed between the two vertical plates, and the two sliders are respectively helically connected to both sides of the first bidirectional threaded rod through threaded holes.

[0011] By adopting the above technical solution, a vertical plate and a first bidirectional threaded rod are set up. Rotating the first bidirectional threaded rod causes the two sliders to slide synchronously toward the middle of the first bidirectional threaded rod or synchronously slide away from the middle of the first bidirectional threaded rod.

[0012] Furthermore, the first bidirectional threaded rod has one end near the fixed seat passing through the vertical plate and equipped with a first bevel gear. Both of the two movable plates have rotating holes on one side near the fixed seat. A rotating column is rotatably installed in the rotating hole. A second bevel gear is fixedly sleeved on the rotating column. The second bevel gear meshes with the corresponding first bevel gear. A square hole is opened on the rotating column. Two horizontal plates are spaced apart on the fixed seat. A square rod is rotatably installed between the two horizontal plates. The square hole and the square rod are in sliding fit. One end of the square rod passes through the horizontal plate and is equipped with a rotating handle.

[0013] By adopting the above technical solution, a first bevel gear, a rotating column, a second bevel gear, and a square rod are provided. Rotating the handle drives the square rod to rotate, causing the two rotating columns and the second bevel gear to rotate, which in turn drives the two first bevel gears to rotate, thereby driving the two first bidirectional threaded rods to rotate, making adjustment convenient. Furthermore, the square hole is slidably connected to the square rod, allowing the rotating column to slide relative to the square rod when the moving plate moves. This ensures that even when the rotating column slides to any position, the square rod can still drive the rotating column to rotate.

[0014] Furthermore, the clamp is located exactly in the middle of two sliders on the same movable plate.

[0015] Furthermore, a first rubber sheet is provided on each adjacent side of the two clamping plates, and a second rubber sheet is provided on the surface of the clamping column.

[0016] By adopting the above technical solution and setting the first rubber sheet and the second rubber sheet, the first rubber sheet and the second rubber sheet are made to contact the gas pipeline, resulting in a better fixing effect.

[0017] Furthermore, the fixed base is provided with a sliding groove, and the sliding block is slidably disposed in the sliding groove.

[0018] By adopting the above technical solution, a groove is opened on the fixed base to ensure the stability of the slider's sliding.

[0019] Furthermore, the drive assembly includes a second bidirectional threaded rod rotatably disposed within the slide groove. The two sliding blocks are respectively helically connected to both sides of the second bidirectional threaded rod through threaded holes. One end of the second bidirectional threaded rod passes through a fixed seat. A drive motor is disposed on the support plate, and the output shaft of the drive motor is connected to the end of the second bidirectional threaded rod that passes through the fixed seat.

[0020] By adopting the above technical solution, a second bidirectional threaded rod and a drive motor are set up. The drive motor drives the second bidirectional threaded rod to rotate, causing the two sliding blocks to slide synchronously toward the middle of the second bidirectional threaded rod or synchronously slide away from the middle of the second bidirectional threaded rod.

[0021] In summary, this utility model has the following beneficial effects: It includes a support plate, a fixed base, a drive assembly, a moving plate, a sliding assembly, clamping plates, and clamping columns. The drive assembly drives two sliding blocks to slide synchronously towards the center of the fixed base, causing the two moving plates to move in the same way, thus clamping the gas pipeline with the two clamping plates. Subsequently, the sliding assembly drives two sliders on the corresponding moving plates to slide towards the clamping plates. The sliding of the sliders causes the mounting blocks and clamping columns to slide until the clamping columns contact the gas pipeline and clamp it. The detection equipment then monitors the gas concentration in real time. At this point, both clamping plates and four clamping columns clamp the pipeline, ensuring that the fixed base and support plate are stably fixed, and eliminating the need to replace components according to pipeline size, making operation convenient.

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-4As shown in the illustration, this application discloses a gas safety detection device, including a support plate 10, a detection device 11, a fixed base 20, a drive assembly 40, and a sliding assembly 60. The detection device 11 and the fixed base 20 are both mounted on the support plate 10. Two sliding blocks 30 are slidably mounted on the fixed base 20. The drive assembly 40 is mounted on the fixed base 20 and drives the two sliding blocks 30 to slide synchronously in opposite directions. A movable plate 50 is horizontally mounted on each of the two movable plates 30. A clamping plate 51 is mounted on each adjacent side of the two movable plates 50. Two sliders 52 are slidably mounted on each movable plate 50. The sliding assembly 60 is mounted on the movable plate 50 and drives the two sliders 52 to slide synchronously in opposite directions. An installation block 54 is mounted on each adjacent side of the sliders 52 on the two movable plates 50. A clamping post 55 is mounted on each installation block 54. The drive assembly 40 drives the two sliding blocks 30 to slide synchronously towards the center of the fixed base 20, causing the two movable plates 50 to move in this way, so that the two clamping plates 51 clamp the gas pipeline. Subsequently, the sliding component 60 drives the two sliders 52 on the corresponding moving plate 50 to slide towards the clamping plate 51. The sliding of the sliders 52 causes the mounting block 54 and the clamping column 55 to slide until the clamping column 55 contacts the gas pipeline and clamps it. Then, the detection device 11 detects the gas concentration in real time. At this time, the two clamping plates 51 and the four clamping columns 55 clamp the pipeline, ensuring that the moving plate 50, the fixed seat 20, and the support plate 10 are stably fixed, and there is no need to replace parts according to the pipeline size, making the operation convenient. The clamping plate 51 is located in the middle of the two sliders 52 on the same moving plate 50. The two clamping plates 51 are provided with a first rubber sheet 56 on their adjacent sides, and the surface of the clamping column 55 is provided with a second rubber sheet 57, so that the first rubber sheet 56 and the second rubber sheet 57 contact the gas pipeline, resulting in a better fixing effect.

[0029] Specifically, the fixed base 20 has a groove 21, and the sliding block 30 is slidably disposed in the groove 21 to ensure the stability of the sliding of the slider 52. The drive assembly 40 includes a second bidirectional threaded rod 41 rotatably disposed in the groove 21. The two sliding blocks 30 are respectively helically connected to both sides of the second bidirectional threaded rod 41 through threaded holes. When the second bidirectional threaded rod 41 rotates, it drives the two sliding blocks 30 to slide synchronously toward the middle of the second bidirectional threaded rod 41 or synchronously slide away from the middle of the second bidirectional threaded rod 41. One end of the second bidirectional threaded rod 41 passes through the fixed base 20, and a drive motor 42 is disposed on the support plate 10. The output shaft of the drive motor 42 is connected to the end of the second bidirectional threaded rod 41 that passes through the fixed base 20, and the drive motor 42 drives the second bidirectional threaded rod 41 to rotate.

[0030] During setup, a strip-shaped hole 53 is provided on the movable plate 50, and the slider 52 is slidably connected to the strip-shaped hole 53 to ensure the stability of the slider 52's sliding. The sliding assembly 60 includes two spaced vertical plates 61 disposed on the side of the movable plate 50 away from the other movable plate 50. A first bidirectional threaded rod 62 is rotatably disposed between the two vertical plates 61. The length direction of the first bidirectional threaded rod 62 is consistent with the length direction of the strip-shaped hole 53. The two sliders 52 are respectively helically connected to both sides of the first bidirectional threaded rod 62 through threaded holes. Rotating the first bidirectional threaded rod 62 causes the two sliders 52 to slide synchronously toward the middle of the first bidirectional threaded rod 62 or synchronously slide away from the middle of the first bidirectional threaded rod 62.

[0031] One end of the first bidirectional threaded rod 62 near the fixed base 20 passes through the vertical plate 61 and is equipped with a first bevel gear 63. Both movable plates 50 have rotating holes on their sides near the fixed base 20. A rotating column 70 is rotatably mounted within the rotating hole. A second bevel gear 71 is fixedly fitted onto the rotating column 70. The second bevel gear 71 meshes with the corresponding first bevel gear 63. Rotation of the rotating column 70 and the second bevel gear 71 drives the two first bevel gears 63 to rotate, thereby driving the two first bidirectional threaded rods 62 to rotate. A square hole 72 is provided on the rotating column 70. Two horizontal plates 73 are spaced apart on the fixed base 20. A square rod 74 is rotatably mounted between the two horizontal plates 73. The square hole 72 and the square rod 74 are in sliding fit. One end of the square rod 74 passes through the horizontal plate 73 and is equipped with a rotating handle 75. Rotating the rotating handle 75 drives the square rod 74 to rotate, causing the two rotating columns 70 and the second bevel gear 71 to rotate. Furthermore, the square hole 72 is slidably connected to the square rod 74, so that when the moving plate 50 moves, the rotating column 70 slides relative to the square rod 74, so that the square rod 74 can still drive the rotating column 70 to rotate even when the rotating column 70 slides to any position.

[0032] The operating principle of the gas safety detection device in this embodiment is as follows: The operator moves the support plate 10 so that the gas pipeline is positioned between the two clamping plates 51. Then, the drive motor 42 is activated to drive the two sliding blocks 30 to slide synchronously towards the center of the fixed base 20, causing the two moving plates 50 to move in this manner, so that the two clamping plates 51 clamp the gas pipeline for initial fixation. Subsequently, the operator rotates the rotating handle 75, causing the square rod 74 to rotate, which in turn causes the two rotating columns 70 and the second bevel gear 71 to rotate, driving the two first bevel gears 63 and the first bidirectional threaded rod 62 to rotate. This causes the two sliders 52, the mounting block 54, and the clamping column 55 to slide synchronously towards the center of the first bidirectional threaded rod 62 until the second rubber sheet 57 contacts the gas pipeline for clamping. The operator then activates the detection equipment 11 to perform real-time detection of the gas concentration.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
