Description

Technical Field

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

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. According to the source of gas, gas can usually be divided into natural gas, artificial gas, liquefied petroleum gas and biomass gas, etc. Gas detectors can collect gas leaks. Whether they are semiconductor, catalytic combustion or infrared gas detectors, they will generate corresponding signals when they detect changes in gas concentration in the environment. These signals are essentially a way to collect gas leaks.

[0003] Existing gas detectors, although relatively compact and handheld, require users to hold the instrument constantly for extended periods, which can easily lead to hand fatigue. Furthermore, when users need to perform other operations simultaneously (such as recording data, checking other components of the gas equipment, etc.), the handheld detector complicates operation, as frequent switching between operating the detector and other actions can affect work efficiency. Therefore, we have introduced a new gas leak detection device. Utility Model Content

[0004] The main purpose of the utility model is to provide a gas leakage collection device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gas leak collection device includes a gas detector, wherein the lower end of the gas detector is fixedly connected to a fixing ring, a connecting mechanism is buckled in the fixing ring, a hanging strap is buckled in the connecting mechanism, the right end of the gas detector is fixedly connected to a limiting mechanism, the upper end of the gas detector is provided with a conduit, and a detection head is provided at the end of the conduit away from the gas detector.

[0007] Preferably, the connecting mechanism includes a lower half ring and an upper half ring, a limiting groove is provided on the upper rear end of the lower half ring, a movable groove is provided on the upper front end of the lower half ring, a through sliding groove is provided on the front wall of the movable groove, a spring is fixedly connected to the lower front end of the upper half ring, a sliding rod is fixedly connected to the front end of the outer surface of the upper half ring, a shift block is fixedly connected to the front end of the slide rod, and a limiting block is fixedly connected to the lower rear end of the upper half ring.

[0008] Preferably, the lower half ring is buckled and connected to the hanging strap, and the upper half ring is buckled and connected to the fixing ring.

[0009] By adopting the above technical solution, the hanging belt can be quickly connected to the gas detector.

[0010] Preferably, one end of the spring away from the upper half ring is fixedly connected to the lower groove wall of the movable groove, and the lower front end of the upper half ring is inserted and connected to the movable groove.

[0011] By adopting the above technical solution, the spring can provide spring stretching and contraction to the upper half ring.

[0012] Preferably, the slide rod is slidably connected to the slide groove, and the limit block is snap-connected to the limit groove.

[0013] By adopting the above technical solution, the upper half ring and the lower half ring can be connected and closed.

[0014] Preferably, the limiting mechanism includes a limiting ring, a fixed block is fixedly connected to the left portion of the outer surface of the limiting ring, a threaded hole is opened on the right portion of the outer surface of the limiting ring, and a limiting screw is threadedly connected to the inner portion of the threaded hole.

[0015] Preferably, the limiting ring is interpenetratingly connected to the detection head, the left end of the fixing block is fixedly connected to the gas detector, and the end of the limiting screw is tightly fitted to the detection head.

[0016] By adopting the above technical solution: inserting the detection head into the limiting ring and locking the limiting ring by the limiting screw, the detection head can be fixed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting a connecting mechanism, the sliding rod is moved upward by the shift block, so that the upper half ring is moved upward, the spring is stretched, and the limit block is disengaged from the limit groove. Then the upper half ring is passed through the fixed ring and the shift block is released. Under the elastic force of the spring, the limit block is clamped into the limit groove, so that the hanging strap can be conveniently and quickly connected to the gas detector. By adding a hanging strap under the gas detector, it is convenient for the user to carry the gas detector with him. During the mobile detection process, there is no need to hold it with hands all the time, freeing up both hands. The user can perform other operations at the same time, such as recording data, checking gas pipelines, valves and other related equipment. The detector can be hung in an easy-to-reach position, such as around the neck or on a work belt, so that it can be quickly taken when needed, saving time. In particular, the detection can be started more quickly in an emergency. At the same time, in areas with complex detection environments, such as narrow spaces, high places or climbing, it can ensure that the gas detector is not easy to fall, reducing the possibility of damage due to falling of the detector, and also avoiding safety hazards caused by falling.

[0019] 2. By setting a limit mechanism, insert the detection head into the limit ring, and lock the limit with the limit screw, the detection head can be fixed. When carrying the gas detector for movement, the detection head may collide with other objects. After the detection head is fixed by the limit, the risk of direct collision of the detection head can be reduced, and damage to the detection head caused by collision can be avoided, thereby ensuring the normal use of the gas detector and reducing the cost of repairing or replacing the detection head.

[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A gas leak collection device includes a gas detector 1, a fixing ring 2 is fixedly connected to the lower end of the gas detector 1, a connecting mechanism 3 is buckled and connected inside the fixing ring 2, a hanging strap 4 is buckled and connected inside the connecting mechanism 3, a limiting mechanism 5 is fixedly connected to the right end of the gas detector 1, a conduit 6 is provided at the upper end of the gas detector 1, and a detection head 7 is provided at the end of the conduit 6 away from the gas detector 1.

[0030] The cam 35 is provided with a spring 36 on the front end of the cam 32 and a spring 37 is provided on the front end of the cam 32. The cam 35 is provided with a spring 36 on the front end of the cam 32. The cam 35 is provided with a spring 36 on the front end of the cam 32. The cam 37 is provided with a sliding block 38 on the front end of the cam 37. The cam 37 is provided with a sliding block 38 on the front end of the cam 37. The cam 37 is provided with a sliding block 38 on the front end of the cam 37. The cam 37 is provided with a sliding block 38 on the front end of the cam 37. The cam 39 is fixedly connected to the cam 33 on the rear end of the cam 32. The cam 31 is buckled and connected to the strap 4. The cam 32 is buckled and connected to the fixed ring 2. The end of the spring 36 away from the upper half ring 32 is fixedly connected to the lower groove wall of the movable groove 34. The cam 37 is slidably connected to the sliding groove 35. The limit block 39 is engaged with the limit groove 33.

[0031] Through the above scheme: the hanging strap 4 can be connected to the gas detector 1 conveniently and quickly. By adding a hanging strap 4 under the gas detector 1, the user can carry the gas detector 1 with him. During the mobile detection process, there is no need to hold it with hands all the time, freeing up both hands. The user can perform other operations at the same time, such as recording data, checking gas pipelines, valves and other related equipment. The gas detector 1 can be hung in an easy-to-reach position, such as around the neck or on a work belt, so that it can be quickly accessed when needed, saving time, especially in an emergency, so that the detection can be started more quickly.

[0032] In this embodiment, the limiting mechanism 5 includes a limiting ring 51, a fixed block 52 is fixedly connected to the left part of the outer surface of the limiting ring 51, a threaded hole 53 is opened on the right part of the outer surface of the limiting ring 51, and a limiting screw 54 is connected to the inner thread of the threaded hole 53. The limiting ring 51 is interlaced with the detection head 7, the left end of the fixed block 52 is fixedly connected to the gas detector 1, and the end of the limiting screw 54 is tightly fitted with the detection head 7.

[0033] Through the above scheme: the detection head 7 is inserted into the limit ring 51, and the limit is locked by the limit screw 54, so that the detection head 7 can be fixed. When the gas detector 1 is carried and moved, it may collide with other objects. After the detection head 7 is limited and fixed, the risk of the detection head 7 being directly hit can be reduced, and damage to the detection head 7 due to collision can be avoided, thereby ensuring the normal use of the gas detector 1 and reducing the cost of repairing or replacing the detection head 7.

[0034] It should be noted that the present invention is a gas leak collection device. During use, by operating the shift block 38, the slide rod 37 is smoothly moved upward. This action drives the upper half ring 32 to lift up, thereby causing the spring 36 to elastically stretch. During this process, the limit block 39 originally embedded in the limit groove 33 is released and freed from the constraint. Subsequently, the upper half ring 32 is passed through the fixed ring 2, and the shift block 38 is released, allowing the natural rebound force of the spring 36 to cause the limit block 39 to automatically reset and tightly embed into the limit groove 33, thereby realizing the quick connection between the hanging strap 4 and the gas detector 1. By adding a hanging strap 4 to the bottom of the gas detector 1, the user no longer needs to hold the instrument continuously when performing the detection task, thereby releasing both hands. The gas detector 1 is convenient for users to carry out multiple tasks such as data recording, gas pipeline and valve inspection at the same time, and allows users to hang the gas detector 1 conveniently around their neck or work belt, which is convenient for easy access at any time and can quickly start detection in an emergency, thereby improving work efficiency and response speed. In addition, in order to ensure the safety of the detection head 7 during carrying, the detection head 7 is inserted into the limit ring 51, and then the limit screw 54 is used to tighten and lock it to achieve a stable limiting effect, which effectively reduces the risk of damage to the detection head 7 due to accidental collision during movement, ensures the overall integrity of the gas detector 1, reduces the maintenance or replacement costs caused by component damage, and ensures the continuity and accuracy of the detection work.
