Description

Technical Field

[0001] The invention belongs to the technical field of laser gas remote detection instruments, and in particular relates to a tube-type laser gas remote detection instrument applied to indoor environments. Background Art

[0002] A laser gas detector is a device that uses laser technology to rapidly detect gas components. Its operating principle is primarily based on spectral absorption technology, specifically tunable semiconductor laser absorption spectroscopy (TDLAS). TDLAS analyzes the selective absorption of laser light by gases to determine gas concentration. Compared to other gas detection technologies, a key advantage of TDLAS is that the spectral width of semiconductor lasers is much smaller than the broadening of gas absorption lines, enabling higher-resolution gas concentration measurements.

[0003] There are two common types of laser gas remote detectors: handheld laser gas remote detectors and pan-tilt laser gas remote detectors;

[0004] Handheld laser gas remote detector: Although it can detect and inspect gas concentration remotely, it requires the operator to be near the site;

[0005] PTZ laser gas remote detector: Although it can realize large-scale remote inspection through automatic scanning without manual operation, it is large in size (generally 30cmLx50cmWx40cmH), heavy in weight, and high in cost, making it unsuitable for small-scale use such as indoors.

[0006] In view of this, a tube-type laser gas remote sensing instrument for indoor environment is proposed. Summary of the Invention

[0031] Reference Figure 1 and 2 A cylindrical laser gas telemeter for indoor use includes a core 100, an outer cover 200, and a telemeter probe 300, wherein the telemeter probe 300 is tilted when set;

[0032] The outer cover 200 is similar to the outer cover of a downlight and is located on the outer periphery of the movement 100, wherein the outer cover 200 is installed on the ceiling through a spring buckle, and the telemeter probe 300 is rotatably configured in the movement 100.

A power connector 101 is installed at the top of the movement 100, wherein the power connector 101 is used to provide power to the whole.

[0033] Reference Figures 2 to 5 The rotation drive mechanism includes a stepper motor 102 and a gear 103. The stepper motor 102 is installed in the movement 100, wherein the back of the movement 100 is provided with a slot for heat dissipation of the stepper motor 102. In order to better reflect the protection position, this solution is not shown in the accompanying drawings. Gear 103 is assembled at the movable shaft of the stepper motor 102, wherein the gear 103 is controlled to rotate by the stepper motor 102.

[0034] Reference Figures 2 to 5 The probe rotation mechanism includes gear 2 104 and an adapter ring 105. Gear 2 104 is engaged with the outer periphery of gear 1 103. The adapter ring 105 is located on the inner edge of gear 2 104. The adapter ring 105 is located on the outer periphery of the telemeter probe 300. When gear 1 103 drives gear 2 104 to rotate, gear 2 104 can drive the telemeter probe 300 to rotate through the adapter ring 105.

[0035] Reference Figure 6 A buzzer 301 is provided at the lower end of the telemeter probe 300, and a detection laser receiving lens 302, an indicator laser emitter 303 and a detection laser emitter 304 are provided on the buzzer 301.

In conjunction with the detectable distance of the telemeter probe 300, the cylindrical laser methane gas telemeter can automatically scan and inspect the concentration of the target gas within a specified spatial range.

[0037] The movement 100 is installed in the outer cover 200, and the outer cover 200 is installed on the ceiling, so that the telemeter probe 300 is aimed at the part to be detected in the room, and a cylindrical laser methane gas telemeter is formed; controlled by a microprocessor, the cylindrical laser methane gas telemeter can monitor and inspect the methane gas leakage concentration in the specified area of ​​the room through automatic scanning; the telemeter probe 300 is connected to the server and the mobile phone through wireless (or wired and wireless), and the server can be connected to the gas valve; the cylindrical laser methane telemeter on the ceiling is used to scan and inspect various detected parts in the room where methane natural gas may leak. Once a gas leak is found, the telemeter can issue an alarm. If the leaked gas is about to reach the warning point, the gas valve can be automatically cut off through linkage; this cylindrical laser methane detector can be used in indoor places such as kitchens in the catering industry and lobbies of hot pot tables that use gas.
