Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for an observation window of a ring network cabinet. Background Art

[0002] As the core unit of the distribution network. The equipment is mainly composed of modular components such as circuit breaker body, load switch body, fuse barrel, insulated busbar and touchable cable connector. All high-voltage live parts are cast with epoxy resin materials with excellent insulation properties, and the vacuum arc chamber, main conductive circuit, insulation support, etc. are organically combined into a whole to achieve a fully insulated, fully sealed, maintenance-free structure. At the same time, it also greatly reduces the insulation gap between the switch phases, completely avoiding phase-to-phase short-circuit faults. Each circuit observes the position status of the three-phase disconnector through three independent observation windows to ensure the safety of operation, inspection and maintenance. In order to improve the insulation performance of some existing ring network cabinets, SF6 insulating gas is generally filled in the cabinet.

[0003] For example, in the Chinese utility model patent with the announcement number CN214124333U and the name SF6 ring main unit, the ring main unit includes a main unit housing, and the main unit includes a lower cabinet body connected to one side surface of the main unit housing, the inner wall of the lower cabinet body is connected to a wire fixing mechanism, and the inner wall of one side of the main unit housing is connected to a high temperature alarm mechanism. Although it can play a certain insulation performance, the internal switch of the SF6 ring main unit is prone to arcing during the opening and closing process, and SF6 will produce sulfur solids under the action of high-voltage arcs. In addition, the arc will also cause part of the metal to vaporize, and the solid particles will be adsorbed on the inner surface of the observation window. Since the ring main unit is filled with insulating gas, the ring main unit needs to be sealed, so that the observation window is not convenient to disassemble, and the stains on the inside of the observation window are not easy to clean, which affects the observation effect. In view of this, the utility model proposes a cleaning device for the observation window of the ring main unit. Utility Model Content

[0031] Example

[0032] like Figure 1-3 As shown, the utility model proposes a ring network cabinet observation window cleaning device, which is installed on a cabinet 1, and includes an observation window 2 arranged on one side of the cabinet 1, so as to facilitate observation of the equipment status in the cabinet 1 through the observation window 2. A cabinet door 11 is also hinged on one side of the cabinet 1, and a sealing rubber ring is also arranged between the cabinet door 11 and the cabinet 1, so that the cabinet 1 presents a closed space. It also includes a cleaning strip 3 arranged on the inner side of the observation window 2, the cleaning strip 3 is made of rubber, and the cross section of the cleaning strip 3 is triangular, the straight end of the cleaning strip 3 contacts the inner surface of the observation window 2, and the cleaning strip 3 cleans impurities on the surface of the observation window 2 when sliding on the surface of the observation window 2.

[0033] For further information, see Figure 1-4, the above cleaning device includes a driving mechanism 4 installed inside the cabinet body 1 to drive the cleaning strip 3 to reciprocate and clean the inner surface of the observation window 2. The driving mechanism 4 includes a rotating shaft 41, a rotating plate 42, a rotating column 43, and a moving frame 44. The rotating shaft 41 arranged above the observation window 2 is rotatably connected to one side of the cabinet body 1. The rotating shaft 41 rotates in place, and at the same time, the rotating shaft 41 is hermetically connected to the cabinet body 1. The rotating plate 42 arranged inside the cabinet body 1 is fixedly connected to one end of the rotating shaft 41. A rotating column 43 is installed on the side of the rotating plate 42 away from the rotating shaft 41. When the rotating shaft 41 rotates, it drives the rotating column 43 to do circular motion through the rotating plate 42. A horizontally arranged moving frame 44 is slidably connected to the rotating column 43. When the rotating column 43 makes circular motion, it drives the moving frame 44 to reciprocate up and down under the limiting action of the limiting rod 46 and the limiting sleeve 47. The driving mechanism 4 further includes a limiting disc 45 fixedly connected to the end of the rotating column 43 away from the rotating plate 42 for limiting to ensure the stability of the movement. The driving mechanism 4 further includes a limiting rod 46, a limiting sleeve 47, and a lifting block 48. At least two groups of limiting rods 46 are fixedly connected to the bottom of the moving frame 44. Each group of limiting rods 46 is slidably connected with a limiting sleeve 47. The limiting sleeve 47 is fixedly connected to the inner wall of the cabinet body 1 to limit the movement of the moving frame 44 when the moving frame 44 moves, so that the moving frame 44 moves smoothly. The bottoms of multiple groups of limiting rods 46 are jointly fixedly connected with a lifting block 48. The lifting block 48 moves synchronously with the moving frame 44, thereby driving the cleaning strip 3 to reciprocate in the up and down direction synchronously. The cleaning strip 3 contacts the inner surface of the observation window 2 to clean the inner surface of the observation window 2. The driving mechanism 4 further includes a handle 49 installed on the side of the rotating shaft 41 away from the cabinet body 1, which is convenient for manually rotating the rotating shaft 41.

[0034] Furthermore, as Figure 3-5 shown, the above cleaning device further includes a pressing component 5 arranged on the side of the cleaning strip 3 away from the observation window 2 to drive the cleaning strip 3 to tightly press on the inner surface of the observation window 2. The pressing component 5 includes a groove 51, a push plate 52, a connecting rod 53, and a mounting plate 54. The groove 51 is opened on the side of the lifting block 48 away from the observation window 2. At least two groups of push plates 52 are arranged in the groove 51 to ensure the stability of the mounting plate 54. A connecting rod 53 is fixedly connected to the side of each group of push plates 52 close to the observation window 2. The connecting rod 53 is slidably connected to the lifting block 48. The mounting plate 54 is fixedly connected to the ends of multiple groups of connecting rods 53 close to the observation window 2. The mounting plate 54 cannot rotate due to the arrangement of multiple groups of connecting rods 53 and moves smoothly. The cleaning strip 3 is installed on the side of the mounting plate 54 away from the connecting rod 53. The pressing component 5 further includes a fixed frame 55 and a spring 56. The fixed frame 55 is arranged in a "U" shape. The fixed frame 55 is installed on the side of the lifting block 48 away from the observation window 2. A spring 56 is arranged between each group of push plates 52 and the fixed frame 55 to release elastic force to make the cleaning strip 3 tightly press on the observation window 2, thereby improving the cleaning effect.

[0035] In this embodiment, when impurities are attached to the inner surface of the observation window 2, the handle 49 is held and rotated, and the rotating shaft 41 keeps rotating in the original position. When the rotating shaft 41 rotates, the rotating column 43 is driven to make a circular motion through the rotating plate 42, and the rotating column 43 slides in the moving frame 44. Since the moving frame 44 moves smoothly under the limiting action of the limiting rod 46 and the fixed limiting sleeve 47, the rotating column 43 slides in the moving frame 44 when the circular motion is made, and at the same time drives the moving frame 44 to make a reciprocating motion up and down, and drives the lifting block 48 to move up and down reciprocatingly. At this time, due to the elastic force of the spring 56, the push plate 52 approaches the observation window 2, and at the same time drives the mounting plate 54 to approach the observation window 2 through the connecting rod 53, and the cleaning strip 3 is pressed against the inner side of the observation window 2, so that when the lifting block 48 reciprocates up and down, the cleaning strip 3 moves synchronously, and the cleaning strip 3 reciprocates up and down and wipes the inner surface of the observation window 2, thereby removing impurities on the inner surface of the observation window 2, achieving the purpose of cleaning, and facilitating observation.

[0036] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
