Description
Technical Field
[0001] This utility model belongs to the field of combustible gas technology, specifically a detection device for a combustible gas detection probe. Background Technology
[0002] In the fields of petrochemicals, coal mining, urban gas transmission, and laboratories, the leakage of combustible gases (such as methane, propane, and ethanol) is a core risk source causing explosions, fires, and poisoning accidents. With the expansion of industrial production and the increase in urban gas penetration, the demand for real-time and accurate monitoring of combustible gas concentrations is becoming increasingly urgent, and combustible gas detection probes have become key equipment for ensuring safety in production and daily life.
[0003] Especially in industrial environments (such as underground coal mines and chemical workshops) and around outdoor gas pipelines, there are often large amounts of dust, oil, flocculent matter, and other impurities. These impurities can easily enter the inside of the detection head through the ventilation holes or adhere to the surface of the ventilation hole protective shell, causing blockage. Once the ventilation holes are blocked, the ambient gas cannot smoothly contact the sensor, resulting in decreased detection accuracy, prolonged response time, and even the risk of "missed detections".
[0004] Therefore, this utility model provides a detection device for a combustible gas detection probe. Utility Model Content
[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a detection device for a combustible gas detection probe is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a detection device for a combustible gas detection probe, including a gas detection probe; a detection head is fixedly installed on the top of the gas detection probe, a protective cover is movably connected to the top of the detection head, support mechanisms are provided on both sides of the top of the gas detection probe, and a rotating component is provided on the top of the support mechanism; a connecting mechanism is provided on the top of the toothed ring, and a cleaning mechanism is provided on the inner wall of the connecting mechanism; a driving mechanism is provided on one side of the bottom of the L-shaped ring, and a detection component is provided on the surface of the detection head; the support mechanism includes a support frame, a mounting plate, and bolts, the bottom sides of the support frame are fixedly installed with the mounting plate, the mounting plate is fixedly connected to the gas detection probe by bolts, and the support frame is located on both sides of the top of the gas detection probe; the cooperation of the support frame, mounting plate, and bolts can provide stable support for the rotating component so that it can be used normally, and at the same time, it can be easily disassembled by the user for maintenance and repair.
[0007] Preferably, the rotating assembly includes an L-shaped ring and a toothed ring. The top of the support frame is fixedly installed with the L-shaped ring, and the L-shaped ring and the toothed ring are rotatably connected. In this design, the L-shaped ring can provide guidance for the toothed ring, enabling it to rotate stably. The toothed ring can drive the connecting mechanism to rotate through the drive mechanism.
[0008] Preferably, the connecting mechanism includes a shaft frame, a crossbar, and side plates. The shaft frame is fixedly installed on both sides of the top of the gear ring. The inner wall of the shaft frame is rotatably installed with the crossbar. The two sides of the crossbar are fixedly installed with the side plates. In this scheme, the cooperation of the shaft frame, crossbar, and side plates can provide stable support for the detector body and the cleaning mechanism, enabling them to rotate synchronously with the crossbar, thereby achieving the cleaning function.
[0009] Preferably, the cleaning mechanism includes a telescopic rod, a spring, and a scraper. Several sets of telescopic rods are provided, and these sets are laterally slidably connected to the inner wall of a crossbar. The bottom of the crossbar near the telescopic rod is fixedly installed with a spring, the bottom of the spring is fixedly connected to a scraper, and the scraper is fixedly connected to the telescopic rod. In this design, the coordinated use of the telescopic rod, spring, and scraper continuously cleans the dust from the surface of the protective cover as the crossbar rotates, preventing dust accumulation from affecting detection. Simultaneously, the spring pushes the scraper to ensure it remains in close contact with the surface of the protective cover.
[0010] Preferably, the driving mechanism includes an L-shaped bracket, a motor, and driving teeth. The L-shaped bracket is fixedly installed on one side of the bottom of the L-shaped ring, the inner wall of the L-shaped bracket is fixedly installed with the motor, the output end of the motor is fixedly installed with the driving teeth, and the driving teeth mesh with the toothed ring. In this scheme, the combined use of the L-shaped bracket, the motor, and the driving teeth can achieve the effect of driving the toothed ring to rotate, so that it has sufficient power to rotate, and at the same time, the dust removal can be automated.
[0011] Preferably, the detection component includes a detector body and ventilation holes. The detector body is fixedly installed on the inner wall of the side plate, and the ventilation holes are opened on both sides of the surface of the detection head. In this solution, the detector body can monitor the usage status of the sensor inside the detection head in real time. When damage occurs, it can promptly issue an alarm to remind the user and ensure the safety of use. The opening of the ventilation holes can prevent the inside of the detection head from becoming stuffy, thereby allowing air to circulate and ensuring that the sensor is not damaged due to moisture.
[0012] The beneficial effects of this utility model are as follows: 1. The detection device for a combustible gas detection probe of this utility model, through the arrangement of a support frame, mounting plate, bolts, L-shaped ring and toothed ring, enables the support frame, mounting plate and bolts to provide stable support for the rotating component so that it can be used normally.

At the same time, the spring can push the scraper to keep it in close contact with the surface of the protective cover. Attached Figure Description

[0018] Specific implementation examples are given below.
[0019] like Figures 1 to 5 As shown in the embodiment of this utility model, a detection device for a combustible gas detection probe includes a gas detection probe 1; a detection head 2 is fixedly installed on the top of the gas detection probe 1, and a protective cover 3 is movably connected to the top of the detection head 2; support mechanisms 4 are provided on both sides of the top of the gas detection probe 1, and a rotating component 5 is provided on the top of the support mechanism 4; a connecting mechanism 6 is provided on the top of the toothed ring 52, and a cleaning mechanism 7 is provided on the inner wall of the connecting mechanism 6; a driving mechanism 8 is provided on one side of the bottom of the L-shaped ring 51, and a detection component 9 is provided on the surface of the detection head 2; the support mechanism 4 includes a support frame 41, a mounting plate 42, and bolts 43, the two sides of the bottom of the support frame 41 are fixedly installed with the mounting plate 42, and the mounting plate 42 is fixedly connected to the gas detection probe 1 by bolts 43, and the support frame 41 is located on both sides of the top of the gas detection probe 1; the rotating component 5 includes an L-shaped ring 51 and a toothed ring 52, the top of the support frame 41 is fixedly installed with the L-shaped ring 51, and the L-shaped ring 51 and the toothed ring 52 are rotatably connected; the connecting mechanism 6 includes a shaft frame 61, a cross-shaped frame 62, and a rotating component 52. The rod 62 and side plate 63, and the shaft bracket 61 are fixedly installed on both sides of the top of the toothed ring 52. The inner wall of the shaft bracket 61 is rotatably installed with the crossbar 62, and the two sides of the crossbar 62 are fixedly installed with the side plate 63. The cleaning mechanism 7 includes a telescopic rod 71, a spring 72, and a scraper 73. Several sets of telescopic rods 71 are provided, and the several sets of telescopic rods 71 are laterally slidably connected to the inner wall of the crossbar 62. The bottom of the crossbar 62 near the telescopic rod 71 is fixedly installed with the spring 72, and the bottom of the spring 72 is fixedly connected with the scraper 73. The drive mechanism 8 is fixedly connected to the telescopic rod 71. It includes an L-shaped bracket 81, a motor 82, and a drive gear 83. The L-shaped bracket 81 is fixedly installed on one side of the bottom of the L-shaped ring 51. The inner wall of the L-shaped bracket 81 is fixedly installed with the motor 82. The output end of the motor 82 is fixedly installed with the drive gear 83. The drive gear 83 meshes with the gear ring 52. The detection component 9 includes a detector body 91 and a ventilation hole 92. The detector body 91 is fixedly installed on the inner wall of the side plate 63. The ventilation hole 92 is opened on both sides of the surface of the detection head 2.
[0020] like Figures 1 to 5As shown, the cooperation of the support frame 41, mounting plate 42, and bolts 43 provides stable support for the rotating assembly 5, enabling it to function normally. It also facilitates disassembly for maintenance and repair. The L-shaped ring 51 guides the toothed ring 52, allowing it to rotate stably. The toothed ring 52, driven by the drive mechanism 8, drives the connecting mechanism 6 to rotate. The cooperation of the shaft frame 61, crossbar 62, and side plate 63 provides stable support for the detector body 91 and the cleaning mechanism 7, allowing them to rotate synchronously with the crossbar 62, thus achieving the cleaning function. The cooperation of the telescopic rod 71, spring 72, and scraper 73 prevents the crossbar 62 from rotating uncontrollably. The dust on the surface of the protective cover 3 is cleaned to prevent dust accumulation from affecting the detection. At the same time, the spring 72 can push the scraper 73 to keep it in close contact with the surface of the protective cover 3. The cooperation of the L-shaped bracket 81, motor 82 and drive gear 83 can realize the effect of driving the gear ring 52 to rotate, so that it has sufficient power to rotate, and at the same time, the dust cleaning can be automated. The detector body 91 can monitor the usage status of the sensor inside the detection head 2 in real time. When damage occurs, it can promptly issue an alarm to remind the user and ensure the safety of use. The opening of the ventilation hole 92 can prevent the inside of the detection head 2 from being stuffy, so that air can circulate and ensure that the sensor is not damaged by moisture.
[0021] Working principle: During operation, first install the gas detection probe 1 in the usage position, and then start using it. During use, the detection head 2 will monitor the working status of the gas detection probe 1 in real time. When it is necessary to detect the detection head 2, first start the detector body 91 to detect the status of the detection head 2. During long-term use, a lot of dust will accumulate on the surface of the protective cover 3. At that time, the detector body 91 will be unable to effectively detect the detection head 2 due to the influence of dust. At this time, the user needs to start the motor 82 to drive the drive gear 83 to rotate. When the drive gear 83 rotates, it will drive the gear ring 52 to rotate. The rotation of the gear ring 52 will drive the shaft frame 61 to rotate. When the shaft frame 61 rotates, it will drive the crossbar 62 and the side plate 63 to rotate. As the crossbar 62 rotates continuously, the scraper 73 can continuously scrape away the dust on the surface of the protective cover 3, so that the detector body 91 can clearly and accurately detect the detection head 2.
