[0023] The application will be described in further detail below with reference to the drawings and embodiments.

[0024] Embodiment 1

[0025] In this embodiment, a mobile GIS installation fresh air purification device is provided, as shown in the drawings, comprising a fresh air purification device 3 installed at a dustproof shed and communicating with the inside of the dustproof shed, and an air outlet pipe 2 is further arranged at the dustproof shed, and an air extraction device is further arranged at the air outlet pipe 2. Figures 1-6

[0026] The air inlet end of the fresh air purification device 3 is provided with an air inlet pipe 1, and the fresh air purification device 3 is used to flow the air sucked by the air inlet pipe 1 into the dustproof shed 4 after purification, and the front end of the air inlet pipe 1, that is, the inlet end of the air inlet pipe 1 is provided with an air inlet filter assembly, and the air purification device 3 is an industrial air purification device that can be purchased on the market, which is used to flow the air sucked by the air inlet pipe 1 into the dustproof shed 4 after purification.

[0027] The air inlet filter assembly comprises a filter cloth mounting rack 101 capable of being mounted at the pipe opening of the air inlet pipe 1, and a filter cloth 102 capable of covering the pipe opening of the air inlet pipe 1 is mounted on the filter cloth mounting rack 101.

[0028] The air inlet filter assembly is used for pretreatment of the air entering the air inlet pipe 1, so that the dust content in the air entering the air inlet pipe 1 is reduced by filtering through the filter cloth 102 before entering, so as to reduce the fresh air purification device and improve the service life of the filter element in the fresh air purification device. Among them, the filter cloth 102 can be made of non-woven fabric, polyester fiber or polypropylene fiber and the like.

[0029] In order to facilitate the installation and quick replacement of the filter cloth 102, the filter cloth mounting rack 101 is structurally designed in this embodiment, specifically:

[0030] ​The filter cloth mounting frame 101 comprises two mounting frame assemblies 103 capable of being clamped at the pipe opening of the air inlet pipe 1, each of the two mounting frame assemblies 103 is provided with a filter cloth winding cavity 104, the filter cloth winding cavity 104 is provided with a filter cloth winding roller 105, the opposite sides of the two mounting frame assemblies 103 are provided with filter cloth extension outlets 106 communicating with the filter cloth winding cavities 104, and the two ends of the filter cloth 102 extend into the filter cloth winding cavities 104 through the two filter cloth extension outlets 106 and are wound on the filter cloth winding roller 105.

[0031] The filter cloth mounting frame 101 is clamped at the pipe opening of the air inlet pipe 1 through the two mounting frame assemblies 103 and the mounting frame connecting rod, wherein the clamping side can be provided with a rubber pad with elasticity to ensure the clamping stability; the mounting frame connecting rod 107 for connecting the two mounting frame assemblies 103 is arranged between the two mounting frame assemblies 103, the connecting rod mounting seat 108 is arranged on each of the two mounting frame assemblies 103, and the two ends of the mounting frame connecting rod 107 pass through the connecting rod mounting seats 108 on the two mounting frame assemblies 103 and are fastened on the connecting rod mounting seats 108 through the fastening nuts 109.

[0032] The two ends of the mounting frame connecting rod pass through the connecting rod mounting seats 108 on the mounting frame assemblies 103 and are fastened through the fastening nuts 109, and then the distance between the two mounting frame assemblies 103 can be adjusted through the mounting frame connecting rod, so that on the one hand, the two mounting frame assemblies 103 can be clamped and mounted on the pipe opening of the air inlet pipe 1, and on the other hand, the filter cloth mounting frame 101 can be clamped on air inlet pipes 1 with different pipe diameters, so that it can be more flexible.

[0033] In addition, the filter cloth 102 is installed through the filter cloth winding rollers 105 on both sides, which can realize winding of unused filter cloth 102 on one side of the filter cloth winding roller 105, winding of used filter cloth 102 on the other side of the filter cloth winding roller 105 after use for a period of time according to the actual situation, and then quick replacement of the filter cloth 102.

[0034] In the embodiment, the winding roller comprises a roller body 110 located in the filter cloth winding cavity 104 and a roller end head 111 extending out of the filter cloth winding cavity 104, the roller end head 111 is provided with a winding roller limiting mechanism, the winding roller limiting mechanism comprises a rotating limiting ring 112 sleeved on the roller end head 111, the rotating limiting ring 112 can move axially along the roller end head 111 and forms a rotating limiting with the roller end head 111, the end surface of the rotating limiting ring 112 facing the mounting frame assembly 103 is provided with a limiting rod 113 arranged axially along the winding roller, the outer surface of the mounting frame assembly 103 is provided with a limiting hole 114, and the limiting rod 113 can be inserted into the limiting hole 114 under the action of the movement of the limiting ring along the winding roller.

[0035] The winding roller limiting mechanism further comprises two axial limiting rings 115 threadedly connected to the roller body 110, and the filter cloth 102 is limited between the two axial limiting rings 115.

[0036] The winding roller limiting mechanism plays two limiting roles. The first one is to realize the rotation limiting of the filter cloth winding roller 105 through the cooperation of the limiting rod 113 and the limiting hole 114. Specifically, a square hole can be formed in the sidewall of the middle circular hole of the rotation limiting ring 112, and a protrusion that can be inserted into the square hole is arranged on the outer sidewall of the roller end 111, so that when the rotation limiting ring 112 is limited in the limiting hole 114 by the limiting rod 113 and cannot rotate, the filter cloth winding roller 105 cannot rotate either, and the filter cloth 102 on the filter cloth winding roller 105 can work stably in this state.

[0037] When the filter cloth 102 needs to be replaced, the rotation limiting ring 112 only needs to be moved axially and away from the limiting hole 114, so that the limiting rod 113 is disengaged from the limiting hole, and then the rotation limiting ring 112 can be rotated to drive the rotation of the filter cloth winding roller 105, so that the used filter cloth 102 is wound on another filter cloth winding roller 105 from the inlet of the air inlet pipe 1, and the unused filter cloth 102 is covered on the inlet of the air inlet pipe 1. At the same time, in order to facilitate the rotation of the rotation limiting ring 112, a protrusion is arranged on the outer side of the rotation limiting ring 112 to increase the friction and facilitate the rotation operation.

[0038] The second one is to realize the limiting of the position of the filter cloth 102 on the winding roller through the axial limiting ring 115, which can ensure that the filter cloth 102 on the winding roller is wound better, and can ensure that the filter cloth 102 can be smoothly inserted or extracted from the filter cloth outlet 106.

[0039] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application on the basis of one or more embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0040] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the present application are also included in the scope of the present application.
