[0002] Combustible gas refers to a substance that can be ignited and is in a gaseous state at normal temperature and pressure, such as hydrogen, acetylene, ethylene, ammonia and hydrogen sulfide. Combustible gas has the general properties of gas. A combustible gas of one component is called a single gas, and a mixture of two or more combustible gases is called a mixed combustible gas. Combustible gases are mixed in a corresponding combustion-supporting medium in a certain proportion. Under the action of an ignition source, they can cause combustion or explosion. Combustible gas is ejected from the nozzle at a certain flow rate, and its burning speed is determined by the diffusion speed of the combustible gas and the air. A combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases.

[0003] For example, the utility model with announcement number CN209559884U discloses a combustible gas detector fixed-point detection device.

Advantages: simple and reasonable structural design, can choose to open or close the shielding sheet according to environmental conditions, effectively protect the detector, and reduce the damage to the detector by the external environment.

[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing combustible gas detector fixed-point detection devices are installed on the wall through fasteners to improve the stability of the detection device during use, but most combustible gas detectors have a lot of oil stains attached to the outer surface during use in the kitchen, which requires staff to disassemble and clean them regularly, thereby reducing the practicality of the equipment.

[0005] For this reason, a high-altitude combustible gas detector is proposed. Utility Model Content

The utility model provides a high-altitude combustible gas detector.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0011] Furthermore, grooves are provided on the upper surfaces of the X-shaped fixing plate and the two groups of fixing plates, and U-shaped sealing gaskets are clamped inside the grooves of the X-shaped fixing plate and the two groups of fixing plates.

[0012] Furthermore, the protective mechanism includes four groups of L-shaped fixing plates, and the four groups of L-shaped fixing plates are symmetrically installed in pairs on the opposite side of the two groups of fixing plates. The interiors of the two adjacent groups of L-shaped fixing plates are slidably connected with connecting plates, and the interiors of the two groups of connecting plates are installed with filter cloths, and the adjacent sides of the two groups of filter cloths are respectively abutted against the opposite sides of the two groups of fixing plates.

[0025] like Figures 1 to 3 As shown, a combustible gas detector detector at a height comprises a combustible gas detector detector body 1 and an "X"-shaped fixing plate 201, wherein the combustible gas detector detector body 1 is clamped inside the "X"-shaped fixing plate 201, threaded holes are provided on the upper surfaces on both sides of the "X"-shaped fixing plate 201, two sets of internal threads of the "X"-shaped fixing plate 201 are connected with a positioning mechanism 2 for limiting the moving range of the combustible gas detector detector body 1, an air suction mechanism 3 is installed at the bottom of the inner wall of the "X"-shaped fixing plate 201, and a protective mechanism 4 is provided on the front and rear sides of the air suction mechanism 3, and a card slot is provided on the inner walls on both sides of the "X"-shaped fixing plate 201, and a limiting mechanism 5 is slidably connected inside the two sets of card slots of the "X"-shaped fixing plate 201;

[0026] Specifically, by rotating the positioning mechanism 2, the upper surface of the positioning mechanism 2 is adsorbed onto the upper surface of the aluminum gusset plate, so that the positioning mechanism 2 adsorbs and clamps the "X"-shaped fixing plate 201 and the combustible gas detector detector body 1 onto the lower surface of the aluminum gusset plate, thereby shortening the time spent by subsequent staff in the process of installing the combustible gas detector detector body 1, thereby improving the practicality of the device; by triggering the start-up of the combustible gas detector detector body 1, the suction mechanism 3 is triggered to quickly absorb the gas around the combustible gas detector detector body 1 to the front and rear sides of the combustible gas detector detector body 1, so that the air circulation speed around the combustible gas detector detector body 1 is accelerated, thereby improving the accuracy of the combustible gas detector detector body 1 during the detection process.

[0027] like Figures 1 to 3 As shown, the positioning mechanism 2 includes two groups of screw rods 202, and the two groups of screw rods 202 are respectively threadedly connected to the two groups of threaded holes of the "X"-shaped fixing plate 201, and the upper surfaces of the two groups of screw rods 202 are provided with suction cups 203, and the bottom ends of the two groups of screw rods 202 are installed with push rods 204; specifically, when the device is placed inside the kitchen for use, by pushing the "X"-shaped fixing plate 201, the upper surface of the "X"-shaped fixing plate 201 is abutted against the lower surface of the aluminum gusset plate inside the kitchen, and then by pushing the two groups of push rods 204 to drive the two groups of screw rods 202 to rotate, the upper surfaces of the two groups of suction cups 203 are adsorbed on the upper surface of the aluminum gusset plate, so that the positioning The mechanism 2 adsorbs and clamps the “X”-shaped fixing plate 201 and the combustible gas detector detection instrument body 1 onto the lower surface of the aluminum gusset plate, thereby shortening the time spent by subsequent staff in installing the combustible gas detector detection instrument body 1, thereby improving the practicality of the device; conversely, the positions of the two groups of suction cups 203 are moved to the inside of the two groups of threaded holes of the “X”-shaped fixing plate 201, so that the upper surfaces of the two groups of suction cups 203 are quickly disconnected from the lower surface of the aluminum gusset plate, thereby completing the removal of the “X”-shaped fixing plate 201 from the lower end of the aluminum gusset plate, thereby reducing the labor and time spent by subsequent staff in installing and removing the combustible gas detector detection instrument body 1.

[0028] like Figure 1 and Figure 2As shown, the air suction mechanism 3 includes two groups of fixing plates 301, and the two groups of fixing plates 301 are both installed inside the "X"-shaped fixing plate 201. The two groups of fixing plates 301 are both provided with grooves, and blowers 302 are clamped inside the grooves of the two groups of fixing plates 301. The two groups of blowers 302 are respectively arranged on the front and rear sides of the combustible gas detector detector body 1, and the output end of the combustible gas detector detector body 1 and the access ends of the two groups of blowers 302 are electrically connected; specifically, the two groups of blowers 302 are triggered to start during the startup process of the combustible gas detector detector body 1, and the gas around the combustible gas detector detector body 1 is quickly absorbed to the front and rear sides of the combustible gas detector detector body 1, so that the air circulation speed around the combustible gas detector detector body 1 is accelerated, thereby improving the accuracy of the combustible gas detector detector body 1 during the detection process.

[0029] like Figure 2 As shown, grooves are provided on the upper surfaces of the I-shaped fixing plate 201 and the two groups of fixing plates 301, and U-shaped sealing gaskets 6 are clamped inside the grooves of the I-shaped fixing plate 201 and the two groups of fixing plates 301; specifically, the U-shaped sealing gasket 6 is provided on the upper surfaces of the I-shaped fixing plate 201 and the air suction mechanism 3, so that when the upper surface of the I-shaped fixing plate 201 abuts against the top of the wall or the aluminum gusset plate, the upper surface of the U-shaped sealing gasket 6 abuts against the surface of the top of the wall or the aluminum gusset plate, so that the U-shaped sealing gasket 6 blocks the connection between the I-shaped fixing plate 201 and the air suction mechanism 3 and the top of the wall or the aluminum gusset plate, thereby preventing subsequent kitchen fumes from entering the interior of the combustible gas detector detector body 1 along the connection between the I-shaped fixing plate 201 and the air suction mechanism 3 and the top of the wall or the aluminum gusset plate.

[0032] In summary: by pushing the I-shaped fixing plate 201, the upper surface of the I-shaped fixing plate 201 is abutted against the lower surface of the aluminum gusset plate inside the kitchen, and then by pushing the two sets of push rods 204 to drive the two sets of screws 202 to rotate, the upper surfaces of the two sets of suction cups 203 are adsorbed on the upper surface of the aluminum gusset plate, so that the positioning mechanism 2 adsorbs and clamps the I-shaped fixing plate 201 and the combustible gas detector detection instrument body 1 on the lower surface of the aluminum gusset plate, thereby shortening the time spent by subsequent staff in the process of installing the combustible gas detector detection instrument body 1; conversely, the positions of the two sets of suction cups 203 are moved to the inside of the two sets of threaded holes of the I-shaped fixing plate 201, so that the upper surfaces of the two sets of suction cups 203 are quickly disconnected from the lower surface of the aluminum gusset plate, thereby completing the removal of the I-shaped fixing plate 201 from the lower end of the aluminum gusset plate, thereby reducing the labor and time spent by subsequent staff in installing and removing the combustible gas detector detection instrument body 1.

[0033] At the same time, by triggering the two sets of blowers 302 to start during the startup process of the combustible gas detector detector body 1, the gas around the combustible gas detector detector body 1 is quickly absorbed to the front and rear sides of the combustible gas detector detector body 1, so that the air circulation speed around the combustible gas detector detector body 1 is accelerated, thereby improving the accuracy of the combustible gas detector detector body 1 during the detection process.
