Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, specifically to a breathing SF6 and oxygen monitoring unit. Background Technology

[0002] SF6 gas is widely used in high-voltage electrical equipment due to its excellent insulation and arc-quenching properties. However, SF6 gas is a greenhouse gas and can be harmful to human health if leaked. At the same time, if the oxygen concentration in the environment where the electrical equipment is located is too low, it can also easily lead to safety accidents. Therefore, it is necessary to monitor the ambient gas in real time through breathing SF6 and oxygen monitoring units.

[0003] Existing breathing monitoring units typically collect gas through natural or active air intake. However, in dusty environments (such as outdoor areas of substations and industrial workshops), dust easily accumulates at the air intake. This can block the air intake channel, hindering gas flow and affecting monitoring response speed. Furthermore, dust may adhere to the monitoring ends of SF6 and oxygen sensors, leading to decreased monitoring accuracy or even damage to the sensors. The dustproof structure of existing monitoring units is mostly a fixed filter, requiring the entire monitoring unit casing to be disassembled for cleaning, which is cumbersome and inefficient. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 The breathing SF6 and oxygen monitoring unit includes a main body 1. An inlet pipe 2 and an outlet pipe 3 are installed at the bottom of the main body 1. A separation mechanism 4 is provided at the bottom end of the inlet pipe 2, and a collection mechanism 5 is provided at the bottom end of the separation mechanism 4. A connection mechanism 6 is provided at the connection between the inlet pipe 2 and the separation mechanism 4. After the gas is separated and filtered by the separation mechanism 4, the dust is collected by the collection mechanism 5. The gas enters the main body 1 for monitoring through the inlet pipe 2 and is then discharged through the outlet pipe 3.

[0028] The separation mechanism 4 includes a cavity cylinder 41 and a tangential pipe 42 installed on the surface of the cavity cylinder 41. A connecting pipe 43 is fixedly sleeved on the top plate of the cavity cylinder 41. When the gas enters the cavity cylinder 41 through the tangential pipe 42, under the action of centrifugal force, the dust rotates downward along the inner wall of the cavity cylinder 41 until it falls to the bottom of the cavity cylinder 41. The gas enters the main body 1 through the connecting pipe 43 and the air inlet pipe 2 for monitoring.

[0029] Furthermore, the collection mechanism 5 includes a material drop chute 51 located at the bottom of the cavity of the hollow cylinder 41, and a collection box 52 disposed on the inner wall of the material drop chute 51. A receiving plate 53 is installed at the bottom of the collection box 52, and an elastic member 54 is disposed between the hollow cylinder 41 and the material drop chute 51. Dust falling along the inner wall of the hollow cylinder 41 falls into the collection box 52 through the material drop chute 51 for collection. By providing the elastic member 54, the collection box 52 can be quickly disassembled, thereby enabling rapid cleaning of the dust.

[0030] The elastic component 54 includes a fixing ring 541 fixedly sleeved on the surface of the hollow cylinder 41, and a hollow rod 542 fixedly installed at the bottom of the fixing ring 541. A T-shaped rod 543 is slidably sleeved inside the bottom end of the hollow rod 542. A spring 544 is provided on the outside of the T-shaped rod 543 and located inside the hollow rod 542. The bottom of the T-shaped rod 543 is fixedly connected to the top of the receiving plate 53. By pulling down the receiving plate 53, the T-shaped rod 543 can move downward and the spring 544 can be compressed until the distance between the receiving plate 53 and the hollow cylinder 41 is greater than the height of the collection box 52. Then the collection box 52 can be removed for cleaning. After cleaning, the collection box 52 is placed on the receiving plate 53. When the receiving plate 53 is released, the receiving plate 53 can move in the opposite direction under the action of the restoring force of the spring 544, thereby completing the locking and fixing of the collection box 52.

[0031] It should also be noted that a limiting ring 55 is fixedly connected to the top of the receiving plate 53, and the inner wall of the limiting ring 55 is in contact with the surface of the collection box 52. By setting the limiting ring 55, the collection box 52 can be limited when it is placed on the receiving plate 53. There are multiple elastic components 54, and the multiple elastic components 54 are equidistantly arranged on the same circle with the cavity cylinder 41 as the axis. This can increase the stability of the receiving plate 53.

[0032] Furthermore, the connecting mechanism 6 includes a connecting ring 61 and two fixing grooves 62 formed on the surface of the connecting ring 61. The fixing grooves 62 are threaded with fixing bolts 63. When connecting the intake pipe 2 and the separation mechanism 4, the connecting ring 61 is placed on the connection between the intake pipe 2 and the connecting pipe 43, and then the two fixing bolts 63 are inserted into the two fixing grooves 62 respectively to fix the connecting pipe 43 and the intake pipe 2. The connecting ring 61 has an embedding groove inside, and a sealing ring 64 is installed inside the embedding groove. By setting the sealing ring 64, the sealing between the connecting pipe 43 and the intake pipe 2 can be increased.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
