Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas detection technology, and in particular to a combustible gas leak detector. Background Technology
[0002] Gas detection refers to the technology and process of detecting and analyzing various gases in the environment to determine their type, concentration, and state of existence. In industries such as petroleum, chemical, coal mining, and steel, gas detection is used to monitor gas leaks, explosion hazards, and personnel safety during production processes.
[0003] Existing gas detection methods utilize the combustion reaction of combustible gases under the action of a catalyst to generate heat, which raises the temperature of the sensor and causes a change in resistance to detect gas concentration. However, this process requires a person to hold the detector and enter the detection area, which could lead to accidents due to close contact between the detection personnel and combustible gases. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a combustible gas leak detector, which aims to improve the problem of accidents caused by the need for personnel to hold the detector and enter the detection area, resulting in close contact between the detection personnel and combustible gas.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A combustible gas leak detector includes a base, a mounting base fixedly connected to the lower surface of the base, a display screen fixedly connected to the upper surface of the base, a connecting column one fixedly connected to the front outer wall of the base, a connecting column two fixedly connected to the outer wall of the connecting column one, a connecting block fixedly connected to the inside of the connecting column one, a receiving screen fixedly connected to the outer wall of the connecting column two, a connecting column three fixedly connected to the rear outer wall of the base, and a laser emitter fixedly connected to the outer wall of the connecting block.
[0007] Preferably, the outer wall of the connecting column three is fixedly connected to a shell, the inner wall of the shell is rotatably connected to a turntable, the inner wall of the turntable is provided with a rotating block, the outer wall of the rotating block is provided with a limit component, the outer wall of the turntable is fixedly connected to a lever, and the outer wall of the lever is provided with a gripping component.
[0008] Preferably, the limiting component includes a limiting post, the outer wall of which is fixedly connected to the outer wall of the rotating block, and a limiting groove is formed inside the outer shell.
[0009] Preferably, the grip assembly includes a handle, the outer wall of which is fixedly connected to the outer wall of the paddle, and a grip groove is formed inside the handle.
[0010] Preferably, the inner wall of the turntable is provided with a limiting groove.
[0011] Preferably, the turntable has wiring holes inside.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, a laser with a wavelength of 1654nm is emitted by a laser emitter. After the laser passes through the monitoring area, it is reflected and received by the receiving screen. When the laser passes through combustible gas, it is absorbed. The receiving screen will detect the change in laser intensity and display it on the display screen in real time, and finally obtain the detection concentration. Thus, the effect of remotely detecting whether there is a combustible gas leak in the monitoring area can be achieved.
[0014] 2. In this utility model, before charging the three pairs of detectors by connecting the column, the handle is rotated to drive the dial to rotate. At this time, the turntable rotates with the dial, and then the rotating block slides with the turntable. In turn, the limiting column slides with the sliding of the rotating block, and finally achieves the purpose of controlling the opening and closing of the rotating block. At this time, the wiring hole is no longer blocked by the rotating block, thereby achieving the effect of preventing water and dust from entering the detector charging port.

Detailed Implementation
[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a combustible gas leak detector, including a base 1, a mounting base 7 fixedly connected to the lower surface of the base 1, a display screen 2 fixedly connected to the upper surface of the base 1, a connecting column 3 fixedly connected to the front outer wall of the base 1, a connecting column 4 fixedly connected to the outer wall of the connecting column 3, a connecting block 5 fixedly connected to the inside of the connecting column 3, a receiving screen 6 fixedly connected to the outer wall of the connecting column 4, a connecting column 8 fixedly connected to the rear outer wall of the base 1, and a laser emitter 9 fixedly connected to the outer wall of the connecting block 5.
[0023] Specifically, a laser of a specified wavelength (1654nm) is emitted by the laser emitter 9. After passing through the area to be detected, the laser is reflected back to the receiving screen 6 by the object. If the laser is absorbed by the characteristic gas, the receiving screen 6 will detect the change in laser intensity and feed it back to the display screen 2. The mounting base 7 is fixed on the lower side of the base 1 to ensure the stability of the detector when it is working. Finally, the detection concentration is obtained, so as to achieve the effect of detecting whether there is a flammable gas leak in the monitoring area.
[0024] Reference Figure 3 A housing 10 is fixedly connected to the outer wall of the connecting column 3 8. A turntable 11 is rotatably connected to the inner wall of the housing 10. A rotating block 12 is provided on the inner wall of the turntable 11. A limit component is provided on the outer wall of the rotating block 12. A lever block 16 is fixedly connected to the outer wall of the turntable 11. A grip component is provided on the outer wall of the lever block 16. The grip component includes a handle 17. The outer wall of the handle 17 is fixedly connected to the outer wall of the lever block 16. A grip groove 18 is provided inside the handle 17.
[0025] Specifically, the detector is charged through the connecting column 3 8, then the handle 17 drives the lever 16 to rotate, and then the turntable 11 rotates under the drive of the lever 16, and then the turntable 11 drives the rotating block 12 to slide.
[0026] Reference Figure 3 and Figure 4 The limiting component includes a limiting post 13, the outer wall of which is fixedly connected to the outer wall of the rotating block 12. A limiting groove 14 is provided inside the outer shell 10; a limiting groove 15 is provided inside the inner wall of the turntable 11; and a wiring hole 19 is provided inside the turntable 11.
[0027] Specifically, at this time, the limit post 13 slides under the drive of the rotating block 12, and finally achieves the purpose of controlling the opening and closing of the rotating block 12. At this time, the wiring hole 19 is no longer blocked by the rotating block 12, thereby achieving the effect of preventing water and dust from entering the detector charging port.
[0028] Working principle: When the device is needed, a laser of a specific wavelength is first emitted by the laser emitter 9. After passing through the gas monitoring area, the laser reaches the reflector and is reflected back to the receiving screen 6. If the characteristic gas to be detected exists in the gas area through which the laser passes, the laser will be absorbed by the characteristic gas. The higher the concentration of the characteristic gas, the greater the absorption. The receiving screen 6 will detect the change in laser intensity and transmit it through the base 1, connecting column 3, and connecting column 4 to the display screen 2 for processing. A mounting base 7 is installed below the base 1 to ensure the stability of the detector during operation. Finally, the detected concentration is obtained, thus achieving the detection function. The monitoring area is designed to detect flammable gas leaks. The detector is connected to an external power source for charging via the connecting post 3 8. At this time, the handle 17 is turned by the grip groove 18, causing the lever 16 to rotate. Then, the turntable 11 rotates on the inner wall of the outer shell 10 under the action of the lever 16. The turntable 11 then causes the rotating block 12 to slide inside the limiting groove 2 15. At the same time, the limiting post 13 slides inside the limiting groove 14 under the action of the rotating block 12, thus achieving the purpose of controlling the opening and closing of the rotating block 12. At this time, the wiring hole 19 is no longer blocked by the rotating block 12, thereby preventing water and dust from entering the detector's charging port.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
