Description

Technical Field

[0001] This utility model relates to the field of tunnel gas detection technology, specifically to an explosion-proof heat dissipation shell for a tunnel gas detector. Background Technology

[0002] A tunnel gas detector is a specialized instrument used in tunnel environments to detect and monitor the concentration of toxic, harmful, or flammable gases in the air within tunnels in real time, and to issue an alarm when the concentration exceeds the standard. It typically employs high-sensitivity sensors capable of detecting various gases such as carbon monoxide, hydrogen sulfide, methane, and oxygen. It is widely used in the construction and operation phases of tunnels in highways, railways, and subways to ensure personnel safety and environmental control.

[0003] The outer shell of a tunnel gas detector refers to the external housing structure used to enclose and protect the core components such as electronic components, sensors, and circuit boards inside the detector. It is not only the physical support structure of the instrument, but also undertakes key functions such as dust prevention, corrosion prevention, and impact resistance, ensuring the safe and stable operation of the equipment in complex and harsh environments such as tunnels.

[0004] However, the heat dissipation performance of existing tunnel gas detector housings is poor. If the electronic components inside the tunnel gas detector housing work in a high-temperature environment for a long time, they may explode due to the high temperature, eventually rendering the tunnel gas detector unusable. Therefore, it does not meet the current requirements. In response, we have proposed an explosion-proof heat dissipation housing for tunnel gas detectors. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof heat dissipation shell for a tunnel gas detector, comprising a tunnel gas detector shell, wherein an internal thread mounting groove is provided at the middle position of the lower end face of the tunnel gas detector shell, a cooling fan is provided inside the internal thread mounting groove, an air source distribution pipe is provided above the cooling fan, a first square air source diversion sleeve communicating with the interior is fixed on the upper end face of the air source distribution pipe, and a plurality of first air outlet pipes are provided on the upper end face of the first square air source diversion sleeve.

The upper end face of the external threaded fixing sleeve has a mounting groove at the middle position, and the cooling fan is located inside the mounting groove.

[0008] A ring of force-bearing rod is fixedly provided on the lower side of the outer surface of the external threaded fixing sleeve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] The temperature display screen 2 (model 12864K5), the small temperature sensor 3 (model WZP-035), and the cooling fan 6 (model LFB) mentioned in this utility model can be obtained from the market or through private customization.

[0024] like Figure 1As shown, one embodiment of this utility model provides an explosion-proof heat dissipation housing for a tunnel gas detector, comprising a tunnel gas detector housing 1. An internally threaded mounting groove 4 is provided at the middle position of the lower end face of the tunnel gas detector housing 1. A cooling fan 6 is provided inside the internally threaded mounting groove 4. An air source distribution pipe 7 is provided above the cooling fan 6. A first square air source diversion sleeve 8 communicating with the interior of the air source distribution pipe 7 is fixed to the upper end face of the air source diversion sleeve 7. Multiple first air outlet pipes 9 are provided on the upper end face of the first square air source diversion sleeve 8. When the equipment needs to be used, electronic components for gas detection are installed inside the tunnel gas detector housing 1, and then it can be started.

[0025] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 4 As shown, a temperature display screen 2 is installed on the upper end face of the tunnel gas detector housing 1 near the rear end face. A small temperature sensor 3 is fixedly installed inside the tunnel gas detector housing 1 below the temperature display screen 2, and the temperature display screen 2 and the small temperature sensor 3 are electrically connected. When using electronic components located inside the tunnel gas detector housing 1 for detection, the small temperature sensor 3 can monitor the temperature inside the tunnel gas detector housing 1 in real time and transmit the detection data to the temperature display screen 2 which is electrically connected to it. When the temperature display screen 2 receives the data, it will display the value on the outer surface of its own display screen.

[0026] As a preferred technical solution in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, an arc-shaped air source distribution pipe 10 is provided at each of the four corners of the outer side of the air source distribution pipe 7. All four arc-shaped air source distribution pipes 10 are located above the cooling fan 6, and the lower end face of the arc-shaped air source distribution pipe 10 is in contact with the upper end face of the cooling fan 6. An air source transmission pipe 11 is fixedly connected to one side of the outer surface of the arc-shaped air source distribution pipe 10. The air source transmission pipe 11 is connected to a second square air source diversion sleeve 12, and the four second square air source diversion sleeves 12 are respectively located at the four corners inside the tunnel gas detector housing 1. Multiple second air outlet pipes 13 are provided on the surface of the second square air source diversion sleeve 12 facing the center point inside the tunnel gas detector housing 1. The interior of the air source distribution sleeve 12 is connected to the interior of the tunnel gas detector housing 1 through the second air outlet pipe 13. When the temperature display screen 2 indicates that the temperature inside the tunnel gas detector housing 1 reaches more than 30 degrees Celsius, the cooling fan 6 is activated. The cooling fan 6 can draw in the external air source and transmit it to the interior of one air source distribution pipe 7 and four arc-shaped air source distribution pipes 10 located above it. The air source entering the air source distribution pipe 7 will enter the interior of the first square air source distribution sleeve 8, which is connected to the interior of the air source distribution sleeve 8, and perform heat dissipation on the lower end of the electronic components through the first air outlet pipe 9 located on the upper end of the first square air source distribution sleeve 8.

[0028] This embodiment enables simultaneous heat dissipation of the lower end face and the four corners of the outer surface of the electronic components located inside the housing 1 of the tunnel gas detector, thereby improving the heat dissipation effect of the device itself and preventing the electronic components inside the housing 1 of the tunnel gas detector from malfunctioning due to high temperature.

[0029] The cooling fan 6 has an external threaded fixing sleeve 5 that is installed inside the internal threaded mounting groove 4 via a threaded structure on the outside. The upper end face of the external threaded fixing sleeve 5 has a mounting groove 14 in the middle position, and the cooling fan 6 is located inside the mounting groove 14.

[0030] A ring of force-bearing rods 15 is fixedly provided on the lower side of the outer surface of the external threaded fixing sleeve 5. In this embodiment, the cooling fan 6 used to generate air source is fixed inside the internal threaded mounting groove 4 by the external threaded fixing sleeve 5. The external threaded fixing sleeve 5 is installed inside the internal threaded mounting groove 4 by the thread structure. When the cooling fan 6 fails due to long-term use or other reasons, it can be removed from the internal threaded mounting groove 4 by rotating the external threaded fixing sleeve 5 through the force-bearing rod 15. Then, the cooling fan 6 located inside the mounting groove 14 on the upper end face of the external threaded fixing sleeve 5 can be repaired directly, or it can be directly removed and replaced.

[0031] The above technical solution enables rapid repair or replacement of the cooling fan 6, thereby improving the convenience of the equipment.
