Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a gas leak detection device. Background Technology

[0002] Restaurant and hotel kitchens are high-frequency gas usage areas, with gas consumption far exceeding that of households. Furthermore, the dense concentration of equipment (such as high-powered stoves and steamers) increases the risk of leaks. Therefore, in addition to installing fixed alarms, portable handheld detectors are also required for staff to regularly inspect key components such as stoves, pipe connections, and pressure reducing valves.

[0003] For pipe interfaces located in complex areas, such as those within narrow spaces in building walls, the reach of a worker's arm is limited when using a combustible gas detector (comprising the main body and sensors) due to the building structure. When this reach is less than the distance between the worker and the pipe interface, a misalignment between the sensor and the interface can occur, leading to decreased accuracy of the sensor data and impacting the safe use of gas. To address these shortcomings, we propose a gas leak detection device to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gas leak detection device. It solves the problem that when workers use a combustible gas detector consisting of the detector body and sensors to detect gas leaks at pipe interfaces in complex locations, the worker's arm extension length is fixed. When the arm extension length is less than the distance between the worker and the pipe interface, the sensor and the pipe interface may not correspond, leading to a decrease in the accuracy of the sensor detection data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gas leak detection device, comprising a detector body, a sensor, and a telescopic hose disposed between the detector body and the sensor, wherein a control mechanism is provided at one end of the sensor, and the control mechanism includes:

[0006] The support has a movable block rotatably mounted on its inner surface for supporting the sensor.

[0007] The first telescopic rod assembly is fixedly installed on the bottom surface of the support, and the bottom surface of the moving block is hinged to a second telescopic rod assembly for the angle change of the moving block.

[0008] A housing is fixedly installed on the outer wall of the first telescopic rod assembly. A control screw is rotatably connected inside the housing. A threaded plate that is threadedly connected to the outer wall of the control screw is fixedly connected to the bottom surface of the second telescopic rod assembly.

[0009] Preferably, the first telescopic rod assembly and the second telescopic rod assembly include a set of sleeves and multiple sets of hollow tubes in a sleeved arrangement, and a combined locking block and spring are provided between the sleeves and hollow tubes.

[0010] Preferably, one end of the threaded plate is slidably disposed on the outer wall of the first telescopic rod assembly located inside the housing.

[0011] Preferably, a toggle block is fixedly connected to one end of the control screw that extends outside the housing.

[0012] Preferably, the bottom surface of the movable block is provided with a connecting plate, and one end of the second telescopic rod assembly is hinged between the two sets of connecting plates.

[0013] Preferably, the bottom surface of the movable block is provided with a slide rail for limiting the sliding of the connecting plate.

[0014] Preferably, a clamp is provided at the end of the movable block away from the support.

[0015] Preferably, a handle is fixedly connected to one end of the first telescopic rod assembly.

[0016] This utility model discloses a gas leak detection device, which has the following beneficial effects: The gas leak detection device, through the setting of a support, a moving block, a first telescopic rod assembly, a second telescopic rod assembly, and a telescopic hose, enables the sensor to move to a pipe interface at different distances from the detection personnel. Furthermore, combined with a housing, a control screw, a threaded plate, and a toggle block, the setting position of the second telescopic rod assembly relative to the first telescopic rod assembly can be adjusted, thereby allowing for multi-angle adjustment of the sensor setting angle supported at the moving block. This ensures that the sensor corresponds to the gas leak location in the pipeline, effectively detecting gas leaks in the pipeline. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a gas leak detection device that solves the problem that when workers use a combustible gas detector consisting of a detector body and sensors to detect gas leaks at pipe interfaces in complex locations, the worker's arm extension length is fixed. When the arm extension length is less than the distance between the worker and the pipe interface, the sensor and the pipe interface may not correspond, leading to a decrease in the accuracy of the sensor detection data. This device enables flexible control of the sensor position under complex conditions.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a gas leak detection device.

[0029] According to the appendix Figure 1-6As shown, the device includes a detector body 1, a sensor 2, and a telescopic hose 3 installed between the detector body 1 and the sensor 2. The specific material of the telescopic hose 3 is selected according to the actual situation. The detector body 1, sensor 2, and telescopic hose 3 constitute a combustible gas detector of model HD5L, which can be used to detect gas leaks. Specifically, the inspector holds the detector body 1 in one hand and the sensor 2 in the other hand, and then brings one end of the sensor 2 close to the part of the gas pipeline to be detected. The sensor 2 converts the gas concentration into an electrical signal and transmits the electrical signal to the detector body 1. The inspector judges the data on the display screen of the detector body 1. When a gas leak is found, the detector body 1 can sound an alarm.

[0030] See attached document Figure 2-6 The sensor 2 is equipped with a control mechanism 4 at one end. The control mechanism 4 enables the sensor 2 to be brought close to different detection positions, so that the sensor 2 can detect gas leaks in pipelines in complex environments. The control mechanism 4 includes a support 41. A movable block 42 for supporting the sensor 2 is rotatably provided on the inner surface of the support 41. A clamp 421 is provided at the end of the movable block 42 away from the support 41. The clamp 421 is fitted onto one end of the sensor 2, thereby fixing the sensor 2 and the movable block 42 together.

[0031] See attached document Figure 2-4 The first telescopic rod assembly 43 is fixedly mounted on the bottom surface of the support 41. A second telescopic rod assembly 44 for angle adjustment of the moving block 42 is hinged to the bottom surface of the moving block 42. A connecting plate 45 is provided on the bottom surface of the moving block 42. One end of the second telescopic rod assembly 44 is hinged between two sets of connecting plates 45. A slide rail 451 for limiting the sliding of the connecting plate 45 is provided on the bottom surface of the moving block 42. A handle 5 is fixedly connected to one end of the first telescopic rod assembly 43. The first telescopic rod assembly 43 and the second telescopic rod assembly 44 include a set of sleeves 431 and a set of hollow tubes 432 in a sleeved arrangement, and multiple sets of hollow tubes 432 in a sleeved arrangement. A combined locking block 433 and a spring 434 are respectively provided between the sleeves 431 and the hollow tubes 432, and between adjacent sets of hollow tubes 432. See the attached diagram for details. Figure 3The locking block 433 and spring 434 are used to lock and fix the sleeve 431 and hollow tube 432, as well as two adjacent sets of hollow tubes 432. The handle 5 is fixedly connected to a set of sleeves 431 at the first telescopic rod assembly 43. Specifically, the inspector holds the first telescopic rod assembly 43 and the second telescopic rod assembly 44 through the handle 5, and then pulls the hollow tube 432 away from the sleeve 431 until the locking block 433 at one end of the hollow tube 432 is locked into the locking hole opened on the outer wall of one end of the adjacent set of hollow tubes 432 or the sleeve 431 with the assistance of the elastic force of the spring 434. The overall length of the first telescopic rod assembly 43 and the second telescopic rod assembly 44 can be adjusted so that, with the assistance of the first telescopic rod assembly 43 and the second telescopic rod assembly 44 after the length adjustment, the sensor 2 can be moved to the gas pipeline detection location. For example, if the gas pipeline to be detected is located in a narrow area formed by the building wall due to the obstruction of the building wall, and the inspection personnel cannot enter the narrow area, then with the help of the first telescopic rod assembly 43 and the second telescopic rod assembly 44, the sensor 2 can be controlled to move within the narrow area so that one end of the sensor 2 can be moved to a position corresponding to the gas pipeline to be detected.

[0032] See attached document Figure 5-6 The housing 46 is fixedly installed on the outer wall of the first telescopic rod assembly 43, that is, the housing 46 is fixedly installed on the outer wall of the sleeve 431 of the first telescopic rod assembly 43. The housing 46 is rotatably connected to the inside of the control screw 47. The bottom surface of the sleeve 431 of the second telescopic rod assembly 44 is fixedly connected to the threaded plate 48, which is threadedly connected to the outer wall of the control screw 47. One end of the threaded plate 48 is slidably installed on the outer wall of the first telescopic rod assembly 43 located inside the housing 46. The end of the control screw 47 extending to the outside of the housing 46 is fixedly connected to the actuating block 49. Specifically, by rotating the actuating block 49, the control screw 47 can be driven to rotate. Subsequently, under the action of the threaded connection between the control screw 47 and the threaded plate 48, the second telescopic rod assembly 44 is driven to move up and down along the housing 46 to adjust the setting angle of the moving block 42 controlled by the second telescopic rod assembly 44, so that the sensor 2 clamped and fixed at the moving block 42 can be adjusted at multiple angles.

[0033] In summary, before detecting gas leaks in gas pipelines in complex environments, the sensor 2 is fixed to the moving block 42 using clamp 421. Then, according to the location of the gas pipeline to be detected, the hollow tube 432 is pulled away from the sleeve 431, causing multiple sets of hollow tubes 432 to gradually extend. The extended adjacent sets of hollow tubes 432 and the hollow tube 432 and the sleeve 431 are locked together by the locking block 433, which allows the overall length of the first telescopic rod assembly 43 and the second telescopic rod assembly 44 to be adjusted and fixed. Then, the inspector holds the handle 5 with one hand and, with the assistance of the first telescopic rod assembly 43 and the second telescopic rod assembly 44 after length adjustment and the telescopic hose 3, moves the sensor 2 to the gas pipeline to be detected.

[0034] Next, when there is an angular deviation between the sensor 2 and the part of the gas pipeline to be inspected, the inspector rotates the actuating block 49 by holding the handle 5, causing the control screw 47, which is fixedly connected to the actuating block 49, to rotate. Subsequently, under the threaded connection between the control screw 47 and the threaded plate 48, the second telescopic rod assembly 44, after adjusting its length, moves up and down along the housing 46. This causes the moving block 42, which is hinged at one end of the second telescopic rod assembly 44, to rotate circumferentially around the shaft at the support 41. This allows for adjustment of the setting angle of the moving block 42 and the sensor 2, which is fixedly installed on the moving block 42, ensuring that the detection part of the sensor 2 and the part of the gas pipeline to be inspected are in the corresponding position.

[0035] Finally, sensor 2 is used to detect whether there is a gas leak in the gas pipeline. In particular, when the combustible gas detector is not used, the clamp 421 is first loosened to separate the sensor 2 from the moving block 42. Then the combustible gas detector is placed in the suitcase. Then the first telescopic rod assembly 43 and the second telescopic rod assembly 44 are retracted so that the retracted first telescopic rod assembly 43, the second telescopic rod assembly 44, the support 41 and the moving block 42, which have a smaller overall volume, can be placed in the suitcase for easy carrying. The suitcase is not shown in the attached drawing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
