Technical Field

[0001] This utility model relates to the field of detection equipment technology, specifically to an installation structure for a laser gas sensor. Background Technology

[0002] A search revealed existing technology with announcement number CN214219748U, whose general solution is as follows: A mounting structure for fixing a manhole cover sensor includes a manhole cover body. A fixing lug is fixedly connected to one side of the lower middle portion of the manhole cover body. A connecting plate is movably connected to the upper end of the fixing lug. A fixing cover is fixedly connected to one end of the connecting plate. A fixing plate is fixedly connected to one end of the fixing cover. Bolts are threaded through the surface of the fixing plate. A sealing ring is fixedly connected to the upper end of the fixing cover. A groove is formed on the outer side of the sealing ring at the lower end of the manhole cover body. A fixing seat is fixedly connected to the center of the lower end of the manhole cover body. A spring is fixedly connected inside the fixing seat. Therefore, although the sensor can be installed and fixed, the sensor, its control chip, and power module all need to be concentrated in a small fixing cover, resulting in cramped space inside the fixing cover and making it difficult to effectively distinguish between the sensor, its control chip, and its power module. Utility Model Content

[0003] The purpose of this invention is to provide an installation structure for a laser gas sensor to solve the problems mentioned in the background art.

[0016] Please see Figure 1-5 This utility model provides an embodiment of a laser gas sensor mounting structure, including a mounting assembly 1. The mounting assembly 1 includes a housing 10, and a storage cavity 16 is provided inside the housing 10. The mounting assembly 1 also includes a connecting plate 15, which is connected to the housing 10 to close the storage cavity 16 and is connected to the inner bottom surface of a manhole cover to fix the mounting assembly 1 to the manhole cover. The bottom surface of the housing 10 is also provided with a first interface 113, which is connected and communicates with the inside of the housing 10 and is connected to a sensor 3.

[0017] In summary, because the housing 10 has a storage cavity 16 inside and the sensor 3 is installed on the first interface 113, the working part, control part, and power supply of the sensor 3 can be stored separately, reducing mutual interference between the parts during operation. Furthermore, using the storage cavity 16 to store electrical equipment also allows the housing 10 to protect the equipment. In particular, when the housing 10 is made of iron, the explosion-proof capability of the equipment is improved. Moreover, by increasing the volume of the housing, the contact area between the housing 10 and the air inside the manhole is increased, facilitating the exchange of heat generated inside the housing 10 with the air inside the manhole, thus reducing interference from heat sources on the equipment's operation. Additionally, the connecting plate 15 is movably connected to the housing 10, making the installation and replacement of electrical components inside the storage cavity 16 simple and convenient. This allows users to select appropriate sensors according to their actual needs; for example, when methane needs to be detected, a methane sensor can be installed on the first interface; when carbon dioxide needs to be detected, a carbon dioxide sensor can be installed on the first interface.

[0018] To further enhance the partitioning capability of the storage cavity 16, a connecting seat 11 is provided on the inner bottom surface of the housing 10, and is connected to the provided isolation member 14 through the connecting seat 11. Therefore, the internal space of the storage cavity 16 can be further divided by the isolation member 14, which firstly allows the various electrical components to be separated from each other; secondly, it provides a reliable working position for each electrical component and avoids the phenomenon of the electrical components shaking.

[0019] Based on this, when the manhole cover is run over by a vehicle, the electrical components inside the storage cavity 16 are separated and fixed by the isolation component 14, thus preventing damage to the electrical components caused by the vibration of the manhole cover.

[0020] Furthermore, since the isolation member 14 includes a first connecting part 13, and the first connecting part 13 is also provided with an isolation plate 110, and a wire passage area 111 is formed between any two isolation plates 110, the isolation plate 110 can fix electrical equipment, and the wire passage area 111 facilitates the insertion of wire harnesses.

[0021] To facilitate the installation and connection of the two spacers 14, a second connecting portion 18 is provided above the first connecting portion 13, and the second connecting portion 18 is also provided with a wire through hole 17; wherein, the cross-section of the second connecting portion 18 is polygonal, and the second connecting portion 18 and the first connecting portion 13 are connected and communicated through a through hole 19. Therefore, when assembling the two spacers 14, the first connecting portion 13 of one spacer 14 is first connected to the through hole 19 of the other spacer 14 to realize the assembly of the two spacers 14; since the spacers 14 are easy to assemble inside the storage cavity 16, the number of spacers 14 can be increased to further increase the partitions within the storage cavity 16.

[0022] In addition, since the partition plate 110 is an aluminum plate and the outer wall of the partition plate 110 is attached to the inner wall of the storage cavity 16, the partition plate 110 is attached to the storage cavity 16 so that the heat inside the storage cavity 16 can be quickly transferred to the housing 10, thereby making the device convenient for partitioning while also improving heat dissipation.

[0023] Based on the above solution, since the bottom surface of the housing 10 is also provided with a second interface 114, and is connected to the liquid level float valve 2 through the second interface 114, the water level inside the manhole can be obtained by using the liquid level float valve 2, thus enabling the device to provide early warning of the water level inside the manhole.

[0024] Meanwhile, since the bottom surface of the housing 10 is also provided with a bracket 12, and the bracket 12 is also provided with a communication module 4; the housing 10 is also provided with a third interface 112, and an adapter 5 is installed on the third interface 112, and the wire harness connector of the communication module 4 is connected to the adapter 5, the device can communicate with the outside world in real time, thereby obtaining the information required inside the manhole.

[0025] In addition, since the housing 10 is also provided with a reserved interface 115, other required sensors can be installed through the reserved interface 115 to further enrich the detection capabilities of the device; among them, the sensor 3, the liquid level float valve 2, the communication module 4 and the adapter 5 are all purchased from the market, so they will not be described in detail here.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
