[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Please also refer to Figures 1 to 4The present invention provides a gas detection instrument for explosion-proof areas. The gas detection instrument for explosion-proof areas includes an explosion-proof housing 1, a gas detection sensor 2, a signal processing module 3, a display module 4, and an illuminator 5. The explosion-proof housing 1 has a cavity 11 formed therein, and has a hollow structure 12. The gas detection sensor 2 is connected to the cavity 11 of the explosion-proof housing 1, and the gas to be detected enters the cavity 11 through the hollow structure 12. The gas detection sensor 2 is used to detect the gas. The signal processing module 3 is connected to the cavity 11 of the explosion-proof housing 1, electrically connected to the gas detection sensor 2, and used to receive and process the signal of the gas detection sensor 2. The display module 4 is connected to the cavity 11 of the explosion-proof housing 1, electrically connected to the signal processing module 3, and used to display the gas information after detection. The illuminator 5 is connected to the cavity 11 of the explosion-proof housing 1, and has an illuminator 51 that can pass through the hollow structure 12 and extend out of the explosion-proof housing 1. The illuminator 51 is used for lighting.

[0038] The utility model provides a gas detection instrument for explosion-proof areas. Compared with the prior art, the utility model can protect the gas detection sensor 2, the signal processing module 3, the display module 4 and the illuminator 5 by providing an explosion-proof shell 1, thereby playing an explosion-proof role and being able to be used in explosion-proof areas. The display module 4 can display the gas information after detection, and the illuminator 5 can provide lighting at night. When in use, the lighting lamp 51 is extended out of the hollow structure 12 to realize lighting, and when not in use, it is retracted into the cavity 11. It is convenient to store and flexible to use, and solves the technical problem that the gas detector does not have lighting function and explosion-proof function and is inconvenient to use. The utility model has the technical effect of having lighting function and explosion-proof function, being convenient to use in explosion-proof areas and at night, and being easy to use.

[0039] The gas detection sensor 2, signal processing module 3, and display module 4 in this embodiment are all prior art electronic devices. The combination of the gas detection sensor 2 and signal processing module 3 can be considered a prior art gas detection sensor assembly. Gas enters the explosion-proof housing 1 through the hollow structure 12, enabling detection of gas content and concentration, etc. The detection principle is not explained here. A lighting lamp 51 can be used for illumination, facilitating detection at night. The explosion-proof housing 1 is made of conventional explosion-proof materials. A cavity 11 is formed within the housing to house the gas detection sensor 2, signal processing module 3, display module 4, and illuminator 5, providing explosion-proof functionality. The lighting lamp 51 in this embodiment can be placed inside or outside the explosion-proof housing 1. When illumination is required, it can be placed outside to provide a wider illumination range and facilitate gas detection. When illumination is not required, it can be placed inside to provide a concealed position. The lighting lamp 51 will not be damaged during transportation or relocation of the present invention.

[0040] In some embodiments, see Figures 1 to 4The explosion-proof housing 1 includes an upper shell 13 and a lower shell 14. One side of the upper shell 13 is hingedly connected to the other side of the lower shell 14. The upper shell 13 and the lower shell 14 are tightly attached to each other and, when assembled and docked, form a cavity 11 within. The upper shell 13 and / or the lower shell 14 have a hollow structure 12. The upper shell 13 and the lower shell 14 have similar structures, both being box-shaped and capable of being snapped together. When snapped together, a cavity 11 is formed within. The gas detection sensor 2, signal processing module 3, display module 4, and illuminator 5 are fixed within the lower shell 14, while the upper shell 13 seals the lower shell 14. Once sealed, the gas detection sensor 2, signal processing module 3, display module 4, and illuminator 5 are enclosed within the cavity 11. The connection between the upper shell 13 and the lower shell 14 is similar to the connection method and principle of luggage in the prior art. In this embodiment, the hollow structure 12 is disposed at the upper end of the upper shell 13, but it can also be disposed on the side or the lower shell 14. The upper shell 13 and the lower shell 14 are both made of explosion-proof materials and have an explosion-proof structure.

[0041] In some embodiments, see Figures 1 to 4 The upper housing 13 and the lower housing 14 are respectively connected to a first locking member 15 and a second locking member 16. The first locking member 15 and the second locking member 16 are detachably connected to each other. When connected, the first locking member 15 and the second locking member 16 are tightly abutted. After disassembly, the explosion-proof housing 1 is opened to expose the gas detection sensor 2, the signal processing module 3, and the display module 4. When the upper housing 13 and the lower housing 14 are connected, they are closed. When separated, they are opened to expose the gas detection sensor 2, the signal processing module 3, the display module 4, and the illuminator 5. By moving the explosion-proof housing 1 to different locations in the explosion-proof area, gas detection can be performed at different locations. The explosion-proof housing 1 is flexible and convenient to move. The first locking member 15 and the second locking member 16 are easily locked together, equivalent to the locking structure of the prior art, and can be matched and locked. Disassembly is also relatively easy. After disassembly, the upper housing 13 or the lower housing 14 can be moved to separate the upper housing 13 and the lower housing 14, thereby opening the explosion-proof housing 1. In this embodiment, the upper shell 13 and the lower shell 14 are hinged to each other on one side of the explosion-proof housing 1 , and the upper shell 13 and the lower shell 14 are detachably connected on the other side.

[0042] In some embodiments, see Figures 1 to 3The lighting device 5 includes a battery 52, a telescopic bracket 53, and a switch button 54. The battery 52 is located in the cavity 11 of the explosion-proof housing 1. The battery 52 is used for power supply and has an electrical energy output terminal. One end of the telescopic bracket 53 is connected to the inner wall of the cavity 11 of the explosion-proof housing 1, and the other end is a free end connected to the lighting lamp 51. The lighting lamp 51 is placed inside the cavity 11 of the explosion-proof housing 1 or outside the explosion-proof housing 1 through the hollow structure 12 by the telescopic bracket 53. The switch button 54 is connected to the outer wall of the explosion-proof housing 1, electrically connected to the lighting lamp 51, and used to control the start and stop of the lighting lamp 51. The battery 52 can be charged and discharged multiple times. When it is out of power, it can be charged. When it has power, it can supply power to the lighting lamp 51. The staff can control the on and off of the lighting lamp 51 by operating the switch button 54, which is convenient to operate. The telescopic bracket 53 plays a role in supporting and adjusting the position of the lighting lamp 51. When the telescopic bracket 53 is extended, the lighting lamp 51 can be placed outside the explosion-proof shell 1 for lighting operations; when the telescopic bracket 53 is retracted, the lighting lamp 51 can be placed inside the explosion-proof shell 1. When the explosion-proof shell 1 is transported or moved, the lighting lamp 51 will not be touched or damaged, thereby protecting the lighting lamp 51.

[0043] In order to realize automatic control of the extension and contraction of the telescopic bracket 53, in some embodiments, refer to Figures 1 to 3 The telescopic bracket 53 is a conventional electric telescopic rod capable of extending and retracting along its axis, and the length of the extension is controllable. The electric telescopic rod is electrically connected to the power output terminal of a battery 52, which supplies power to the electric telescopic rod. A control button 55 for controlling the extension and retraction of the electric telescopic rod is attached to the outer wall of the explosion-proof housing 1 and is electrically connected to the control button 55. By manipulating the control button 55, a worker can control the extension and retraction of the electric telescopic rod, thereby adjusting the position of the light 51. In this embodiment, the hollow structure 12 is a hollow structure provided in the explosion-proof housing 1, namely, a through hole or irregular hole provided in the explosion-proof housing 1. The inner diameter of the hole is larger than the outer diameter of the light 51, allowing the light 51 to pass through the hole, i.e., through the hollow structure 12. The outer diameter of the telescopic rod is smaller than the outer diameter of the light 51, ensuring smooth passage of the light 51 through the hollow structure 12.

[0044] To facilitate connection of the explosion-proof housing 1, in some embodiments, refer to Figures 2 to 3 A hook 6 is detachably attached to the outer wall of the explosion-proof housing 1. The hook 6 is used to attach to a wall in an explosion-proof area to secure the explosion-proof housing 1. In this embodiment, the hook 6 secures the explosion-proof housing 1 to a wall or other object, thereby fixing the position of the explosion-proof housing 1. This means that the gas detection sensor 2 can perform gas detection at this location. If the explosion-proof housing 1 needs to be moved, the hook 6 can be removed from the wall and reattached to another location.

[0045] In order to facilitate the staff to hold and move the gas detection, in some embodiments, refer to Figure 3 A handheld handle 7 is connected to the outer wall of the explosion-proof housing 1 and is intended to be gripped by a worker. Holding this handle 7 allows the gas detection sensor 2 to follow the worker's movements, enabling on-the-go gas detection. Specifically, the shape of the handheld handle 7 matches the grip of the human hand, providing a comfortable grip and facilitating gas detection.

[0046] In some embodiments, see Figures 1 to 4 An alarm 8 is connected to the inner wall of the explosion-proof housing 1. This alarm 8 is electrically connected to the signal processing module 3 and is used to generate an alarm signal. A gas detection threshold can be preset in the signal processing module 3. When the concentration of a detected gas exceeds this threshold, the signal processing module 3 sends a signal to the alarm 8, instructing it to issue an alarm signal.

[0047] As preferably, the alarm 8 is an audible and visual alarm 8 or a gas alarm 8, etc., which can emit sound and photoelectric information to remind the staff to pay attention. The alarm 8 is electrically connected to the battery 52, and the battery 52 can power the alarm 8.

[0048] In order to display the detected gas information, in some embodiments, refer to Figures 1 to 4 The display module 4 includes a display screen, which is positioned adjacent to the hollow structure 12. Workers can view the information displayed on the screen through the hollow structure 12. The screen displays gas detection information, and workers can see the information through the hollow structure 12, enabling real-time monitoring of gas information at that location within the explosion-proof area for recording and storage. Because the explosion-proof housing 1 is provided with multiple hollow structures 12, the hollow structure 12 through which the telescopic bracket 53 passes is different from the hollow structure 12 through which workers view the display screen; that is, the two hollow structures 12 are located in different locations.

[0049] In some embodiments, see Figures 1 to 4 The inner wall of the explosion-proof housing 1 is connected to an extension bracket 9, one end of which is connected to the inner wall of the explosion-proof outer wall and the other end is connected to the display screen. With the help of the extension bracket 9, the display screen can be adjusted within the cavity 11 of the explosion-proof housing 1. The extension bracket 9 is a telescopic rod, and the extension direction is set toward the hollow structure 12. The extension bracket 9 is also an electric telescopic rod, which is electrically connected to a control button 55. The control button 55 is set on the outer wall of the explosion-proof housing 1. By operating the control button 55, the extension bracket 9 can be controlled. The display screen can be moved within the cavity 11 to move closer to the hollow structure 12, which is to allow staff to better observe the information on the display screen.

[0050] Specifically, in Figure 3 A charging socket is provided on the right side of the lower shell 14 , and the charging socket is electrically connected to the battery 52 and is used to charge the battery 52 .

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
