Description

Technical Field

[0001] This utility model relates to the technical field of harmful gas concentration detection devices, specifically to a telescopic device for harmful gas concentration detection devices. Background Technology

[0002] During tank cleaning and maintenance operations, especially those involving confined spaces, it is necessary to test the concentration of toxic and hazardous gases at the center of the tank before issuing a work permit. Previously, sampling and analysis personnel would wear breathing apparatus to enter the tank for concentration testing. However, this method has two problems: firstly, it takes a long time to prepare the work permit, reducing work efficiency; secondly, entering the tank without knowing the concentration of toxic and hazardous gases poses a significant safety risk.

[0003] Therefore, the present invention aims to provide a telescopic device for a harmful gas concentration detection device that can solve the above-mentioned problems. Utility Model Content

[0004] To address the aforementioned issues, a telescopic device for detecting hazardous gas concentrations is provided. By placing the hazardous gas concentration detection device on a square fixed plate, and setting a telescopic mechanism at one end of the square fixed plate, analysts can detect the concentration of hazardous gases inside the tank from outside the tank through the telescopic mechanism. This solves the problem that analysts entering the storage tank without knowing the concentration of toxic and hazardous gases inside the tank may lead to a major safety accident.

[0005] To address the problems of existing technologies, this utility model provides a telescopic device for a hazardous gas concentration detection apparatus, including a hazardous gas detector with a square fixed plate below it. One end of the square fixed plate is equipped with a telescopic mechanism, which includes a mesh telescopic section formed by multiple cross-arranged connecting rods. One end of the mesh telescopic section is connected to the square fixed plate, and the end of the mesh telescopic section away from the square fixed plate is connected to a movable seat. A guide groove is provided at the end of the movable seat away from the mesh telescopic section, and a movable rod is slidably connected in the guide groove. The movable rod includes a movable part and a driving part. The movable part has a U-shaped structure. A through hole is provided at the midpoint of two adjacent connecting rods within the mesh telescopic section. A rotating rod is provided at the opening of the U-shaped structure of the movable part. The rotating rod is inserted into the through hole at the midpoint of any pair of adjacent connecting rods in the mesh telescopic section. The driving part is inserted into the guide groove.

[0006] Preferably, the end of the movable seat away from the guide groove is provided with a stabilizing groove that matches the shape of the U-shaped opening of the movable part.

[0007] Preferably, the square fixing plate is provided with casters at the four bottom corners.

[0008] Preferably, a connecting mechanism is provided between the square fixed plate and the telescopic mechanism. The connecting mechanism includes a connecting base fixedly connected to the square fixed plate and a connecting block rotatably connected to the mesh telescopic part. Both the connecting block and the connecting base are provided with threaded holes. The connecting block is provided with a placement groove. When the connecting base is inserted into the placement groove, the threaded holes on the connecting block and the connecting base coincide, and the square fixed plate and the telescopic mechanism are fixedly connected by bolts.

[0009] Preferably, the square fixing plate has a placement frame at the top for placing the harmful gas detector, and a moving groove is opened at the bottom of the placement frame, in which a limiting block for fixing the harmful gas detector is slidably connected.

[0010] Preferably, the movable groove is provided with a limiting rod, and the bottom of the limiting block is provided with a limiting groove that matches the limiting rod, and the limiting rod is inserted into the limiting groove.

[0011] Preferably, a return spring is sleeved on the limiting rod.

[0012] Preferably, the placement frame is provided at equal intervals along the long side of the square fixing plate.

[0013] The advantages of this utility model compared to the prior art are:

[0014] 1. By incorporating a telescopic mechanism, the hazardous gas detector can reach the center of the storage tank for detection without entering a confined space, thus greatly ensuring the safety of the analysts and avoiding the risk of personnel directly entering a potentially hazardous environment.

[0015] 2. The design of the movable seat and movable rod in this utility model, through the cooperation of the guide groove and the rotating rod, realizes precise control of the mesh telescopic part, making the telescopic process more stable and reliable, and improving the accuracy and ease of use of the detection device.

[0016] 3. In this utility model, a placement frame and a limiting block are set on the top of the square fixing plate, which can firmly fix the harmful gas detector and prevent it from shifting or falling during movement or detection. At the same time, the equidistant arrangement of multiple placement frames allows the equipment to process or store multiple harmful gas concentration detection devices at the same time, thus improving work efficiency.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-7As shown: A telescopic device for a hazardous gas concentration detection apparatus includes a hazardous gas detector 1, with a square fixed plate 2 positioned below the detector 1; one end of the square fixed plate 2 is provided with a telescopic mechanism 3, the telescopic mechanism 3 including a mesh telescopic part 31, the mesh telescopic part 31 being formed by a plurality of cross-arranged connecting rods 32, one end of the mesh telescopic part 31 being connected to the square fixed plate 2, and the end of the mesh telescopic part 31 away from the square fixed plate 2 being connected to a movable base 33; the movable base 33 is located away from... A guide groove is provided at one end of the mesh telescopic part 31, and a moving rod 34 is slidably connected in the guide groove. The moving rod 34 includes a moving part 341 and a driving part 342. The moving part 341 has a U-shaped structure. A through hole is provided at the midpoint of two adjacent connecting rods 32 in the mesh telescopic part 31. A rotating rod is provided at the opening of the U-shaped structure of the moving part 341. The rotating rod is inserted into the through hole at the midpoint of any pair of adjacent connecting rods 32 in the mesh telescopic part 31. The driving part 342 is inserted in the guide groove.

[0027] In existing technologies, tank cleaning and maintenance operations involve confined spaces. Before issuing a work permit, the concentration of toxic and harmful gases at the center of the tank needs to be detected. Previously, sampling and analysis personnel had to wear breathing apparatus to enter the tank to conduct concentration testing. To ensure the safety of the analysts, this application provides a telescopic device for detecting harmful gas concentrations. The device includes a harmful gas detector 1, with a square fixing plate 2 below the detector to provide support. One end of the square fixing plate 2 is connected to a telescopic mechanism 3. The core of the telescopic mechanism 3 is a mesh telescopic section 31, formed by multiple intersecting connecting rods 32, possessing both telescopic and stability properties.

[0028] One end of the mesh telescopic part 31 is connected to the square fixed plate 2, and the other end is connected to the movable base 33. A guide groove is opened at one end of the movable base 33, and the movable rod 34 is slidably connected in the groove.

[0029] The movable rod 34 includes a movable part 341 and a driving part 342. The movable part 341 has a U-shaped structure. A through hole is opened at the midpoint of adjacent connecting rods 32 in the mesh telescopic part 31 for the insertion of the rotating rod of the movable part 341. The driving part 342 drives the movable part 341 to move.

[0030] The analyst controls the movement of the drive unit 342 to move the moving unit 341, thereby driving the mesh telescopic unit 31 to extend and retract, which in turn moves the square fixed plate 2.

[0031] Reference Figures 1-4 As shown: The movable seat 33 has a stabilizing groove 35 at the end away from the guide groove, which matches the shape of the U-shaped opening of the movable part 341.

[0032] During the movement, the opening of the U-shaped structure is embedded in the stabilizing groove 35, thereby restricting the movement of the moving rod 34 in the direction perpendicular to the sliding direction and ensuring that the moving rod 34 can only slide along the set direction of the guide groove.

[0033] Reference Figure 1 and Figure 2 As shown: the square fixed plate 2 is provided with casters 21 at the four corners of its bottom.

[0034] The caster wheel 21 serves as a moving component of the device, enabling the entire telescopic device to be easily moved when needed.

[0035] Reference Figures 1-7 As shown: A connecting mechanism 4 is provided between the square fixed plate 2 and the telescopic mechanism 3. The connecting mechanism 4 includes a connecting base 41 fixedly connected to the square fixed plate 2 and a connecting block 42 rotatably connected to the mesh telescopic part 31. Both the connecting block 42 and the connecting base 41 are provided with threaded holes. The connecting block 42 is provided with a placement groove. When the connecting base 41 is inserted into the placement groove, the threaded holes on the connecting block 42 and the connecting base 41 coincide, and the square fixed plate 2 and the telescopic mechanism 3 are fixedly connected by bolts.

[0036] When it is necessary to connect the square fixing plate 2 to the telescopic mechanism 3, first insert the connecting base 41 into the placement groove of the connecting block 42. At this time, the threaded holes on the connecting block 42 and the connecting base 41 will coincide. Then, the connecting base 41 and the connecting block 42 are firmly fixed together with bolts, thereby achieving a stable connection between the square fixing plate 2 and the telescopic mechanism 3.

[0037] Reference Figures 5-7 As shown: The square fixing plate 2 has a placement frame 51 on the top for placing the harmful gas detector 1. The bottom of the placement frame 51 has a moving groove 52, and a limiting block 53 for fixing the harmful gas detector 1 is slidably connected in the moving groove 52.

[0038] The operator can slide the limiting block 53 in the sliding groove 52 to make the limiting block 53 fit tightly against the side of the hazardous gas detector 1, thereby effectively fixing the detector in the placement frame 51. This prevents the detector from shifting or falling due to equipment movement or vibration.

[0039] Reference Figures 5-7 As shown: The moving groove 52 is provided with a limiting rod 55, and the bottom of the limiting block 53 is provided with a limiting groove 54 that matches the limiting rod 55. The limiting rod 55 is inserted into the limiting groove 54.

[0040] The limit rod 55 serves as a guide and limiter, ensuring that the limit block 53 can only slide along the set direction of the moving groove 52, without deviating from the track or rotating.

[0041] Reference Figures 5-7 As shown: A reset spring is fitted on the limiting rod 55.

[0042] When the limiting block 53 slides in the moving groove 52 to fix the harmful gas detector 1, the reset spring will be compressed, so that the limiting block 53 is always pressed against the harmful gas detector 1.

[0043] Reference Figures 5-7 As shown: The placement frame 51 has multiple frames equidistantly arranged along the long side of the square fixing plate 2.

[0044] The equidistant arrangement of multiple placement frames 51 enables the equipment to process or store multiple harmful gas concentration detection devices simultaneously.

[0045] Working principle: The equipment includes a hazardous gas detector 1, with a square fixed plate 2 below it for support. One end of the square fixed plate 2 is connected to a telescopic mechanism 3. The core of the telescopic mechanism 3 is a mesh telescopic part 31, formed by cross-connecting rods 32, which has telescopic stability. One end of the mesh telescopic part 31 is connected to the square fixed plate 2, and the other end of the mesh telescopic part 31 is connected to a movable base 33.

[0046] The movable base 33 has a guide groove, in which a movable rod 34 is slidably connected. The movable rod 34 consists of a movable part 341 and a driving part 342, and the movable part 341 is U-shaped. A through hole is provided at the midpoint of the connecting rod 32 inside the mesh telescopic part 31 for the insertion of the rotating rod of the movable part 341. When the driving part 342 is subjected to external force, it drives the movable part 341 to slide along the guide groove, thereby causing the mesh telescopic part 31 to extend and retract, and driving the square fixed plate 2 and the harmful gas detector 1 above it to move.

[0047] The square fixed plate 2 has casters 21 at the bottom, which makes the equipment easy to move.

[0048] The square fixed plate 2 and the telescopic mechanism 3 are connected by a connecting mechanism 4. The connecting block 42 has a placement groove, the base is inserted into the placement groove, the threaded holes coincide, and the square fixed plate 2 and the telescopic mechanism 3 can be fixed by bolts.

[0049] The square mounting plate 2 has a placement frame 51 on top, and a hazardous gas detector 1 is placed inside the placement frame 51. A moving groove 52 is opened at the bottom inside the placement frame 51, and a limiting block 53 is slidably connected in the moving groove 52. The limiting block 53 is used to fix the detector.

[0050] A limiting rod 55 is provided inside the movable groove 52, and a limiting groove 54 is provided at the bottom of the limiting block 53. A return spring is sleeved on the limiting rod 55, and the spring maintains a certain amount of compression when the limiting block 53 fixes the hazardous gas detector 1.

[0051] Multiple placement frames 51 are provided along the long side of the square fixed plate 2, so that the equipment can store multiple harmful gas concentration detection devices at the same time.

[0052] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
