Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, and more specifically, to a combustible gas detection device with an adjustable detection range. Background Art

[0002] Combustible gas refers to a substance that can be ignited and is in a gaseous state at normal temperature and pressure. In order to avoid dangerous accidents caused by the leakage of combustible gas, it is necessary to use a combustible gas detection device to detect the combustible gas; the existing combustible gas detection device can be installed in a designated place for detection during use, or it can be manually held and moved for detection. Combustible gas often has a peculiar smell. When a room has a peculiar smell, it is necessary to hold the combustible gas detection device in hand to detect the situation. Without knowing the gas concentration, people rush in and inhale a large amount of combustible gas, causing harm to people.

[0003] The utility model patent with patent publication number CN202122303799.X discloses a multifunctional portable combustible gas detection device, including: a detector body, a mounting base is arranged on the left side, and fixing holes are opened on both sides of the mounting base; a fixing mechanism includes a mounting shell wrapped on the outer wall of the mounting base, fixing nails are inserted on both sides of the mounting shell, and one end of the fixing nail is inserted into the fixing hole through the mounting shell, and a reset spring is arranged between the other end of the fixing nail and the outer wall of the mounting shell. The utility model installs the detector body on the mounting shell. By adjusting the extension length of the rod, the detector body can be extended to the position where the gas needs to be detected. Detection is possible without people entering the gas range, thereby improving safety.

[0004] However, in actual use, since the length of the adjustment rod is always limited and the gas is invisible, it is impossible to completely isolate the detection personnel from contact with the gas by extending the adjustment rod, which poses certain safety hazards. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a combustible gas detection device with an adjustable detection range to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combustible gas detection device with an adjustable detection range, comprising a detector body, a mounting seat is provided on the outer side of the detector body, a connecting rod is connected to one side surface of the mounting seat, an adjustment movable component is provided on one side of the detector body, and the adjustment movable component comprises a mounting plate, the mounting plate is arranged on one side surface of the wall, square grooves are provided on both side surfaces of the mounting plate, a sliding groove is provided on one side surface of the mounting plate, and the number of the sliding grooves is set to two, a rack is provided inside the mounting plate, an adapting gear is provided on the outer side of the rack, the adapting gear is meshed with the rack, a connecting shaft is provided on one side of the adapting gear, the connecting shaft passes through the sliding groove, and one end is provided with an explosion-proof motor, the connecting shaft is coaxially rotatably connected with the output end of the explosion-proof motor, a fixing plate is provided on the outer side of the connecting shaft, the fixing plate is movably connected to the connecting shaft, a fixing protrusion is provided on one side surface of the fixing plate, and the cross-sectional shape of the fixing protrusion is set to be rectangular.

[0007] Through the above scheme, it can be seen that one side surface of the mounting plate is first installed on the wall of the room. When it is necessary to measure the gas inside the room, the staff starts the explosion-proof motor 1 through an external power supply. At this time, the explosion-proof motor 1 will drive the connecting shaft to rotate, and then the connecting shaft drives the gear to rotate on the surface of the rack, so that the gear will drive the fixed plate and the fixed protrusion on the top of the fixed plate, the mounting seat and the detector body to move synchronously, thereby realizing the adjustment of the position of the detector body, thereby indirectly realizing the adjustment of the detection range and improving the practicability of the device.

[0008] Preferably, a rotating shaft is provided inside the fixed socket, an explosion-proof motor 2 is provided at one end of the rotating shaft, and an output end of the explosion-proof motor is coaxially rotatably connected to the rotating shaft.

[0009] Through the above scheme, it can be seen that an explosion-proof motor 2 is arranged at one end of the rotating shaft. When the gear drives the detector body to the specified position, the staff starts the explosion-proof motor 2 by connecting the external power supply of the explosion-proof motor 2, thereby using the explosion-proof motor 2 to drive the rotating shaft to rotate, and then the rotating shaft drives the connecting rod, and the connecting rod drives the mounting base fixed at one end thereof to rotate under the drive of the explosion-proof motor 2, thereby realizing the detection of gas concentrations in different directions inside the room, thereby improving the flexibility of the device.

[0010] Technical effects and advantages of the utility model:

[0011] By setting an adjustable movable component, compared with the prior art, firstly, one side surface of the mounting plate is mounted on the wall of the room. When it is necessary to measure the gas inside the room, the staff starts the explosion-proof motor 1 through an external power supply. At this time, the explosion-proof motor 1 will drive the connecting shaft to rotate, and then the connecting shaft drives the gear to rotate on the surface of the rack, so that the gear will drive the fixing plate and the fixing protrusion on the top of the fixing plate, the mounting seat and the detector body to move synchronously, thereby realizing the adjustment of the position of the detector body, thereby indirectly realizing the adjustment of the detection range, and improving the practicality of the device;

[0012] Compared with the prior art, by setting a rotating shaft, an explosion-proof motor 2 is set at one end of the rotating shaft. When the gear drives the detector body to the specified position, the staff starts the explosion-proof motor 2 by connecting the external power supply of the explosion-proof motor 2, thereby using the explosion-proof motor 2 to drive the rotating shaft to rotate, and then the rotating shaft drives the connecting rod, and the connecting rod drives the mounting seat fixed at one end thereof to rotate under the drive of the explosion-proof motor 2, thereby realizing the detection of gas concentrations in different directions inside the room, thereby improving the flexibility of the device.
