[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: an observation window assembly of a power distribution cabinet, which is installed on the cabinet door of the power distribution cabinet and is used to observe the operation of the internal equipment of the power distribution cabinet, including a window frame 3, the middle part of the window frame 3 is hollowed out and a light-transmitting plate 4 is fixedly installed, and cleaning guard plates 5 are arranged on both the inner and outer sides of the light-transmitting plate 4. In this embodiment, the inner side is the side facing the internal equipment of the power distribution cabinet, and the outer side is the side away from the internal equipment of the power distribution cabinet. A connecting frame 10 that can slide up and down along the window frame 3 is movably installed inside the left and right sides of the window frame 3, and the cleaning guard plates 5 on the inner and outer sides are fixedly connected to the connecting frame 10. When the outer cleaning guard plate 5 is manipulated to slide up and down, the inner cleaning guard plate 5 is driven to slide synchronously, wherein an additional guard plate 6 is movably installed on the outer cleaning guard plate 5, and the additional guard plate 6 can independently slide up and down on the surface of the cleaning guard plate 5, so that the additional guard plate 6 can be slid out of the cleaning guard plate 5 when needed to cover the entire light-transmitting plate 4; when it is necessary to observe the internal operation of the power distribution cabinet, the additional guard plate 6 is slid to overlap with the cleaning guard plate 5 to expose part of the light-transmitting plate 4; when it is necessary to observe the inside of the power distribution cabinet through another part of the light-transmitting plate 4, the cleaning guard plate 5 is slid to expose another part of the light-transmitting plate 4.

[0029] In this embodiment, inner and outer through grooves 8 are provided on both inner and outer sides of the edge of the window frame 3, and connecting grooves 9 are provided on the wall surface of the inner and outer through grooves 8 facing the light-transmitting plate 4 at the positions corresponding to the front and rear sides of the light-transmitting plate 4. A connecting frame 10 is slidably installed in the inner and outer through grooves 8, and a connecting plate 11 is fixedly installed at the position of the connecting frame 10 corresponding to the connecting groove 9, wherein the cleaning guard plate 5 is fixedly installed on the connecting plates 11 on the left and right sides, thereby synchronously and fixedly connecting the front and rear two groups of cleaning guard plates 5.

[0030] In a preferred embodiment, a groove is provided on the end edge of the cleaning guard plate 5 close to the light-transmitting plate 4 and a brush edge 12 is fixedly installed. The brush edge 12 is bristles, or cleaning tools such as a cloth strip or a sponge. When the cleaning guard plate 5 slides up and down, the surface of the light-transmitting plate 4 can be cleaned to maintain the transmittance of the light-transmitting plate 4.

[0031] Furthermore, a slider 13 is integrally formed on the inner side of the additional guard plate 6 in the vertical direction. In the present embodiment, the cross-section of the slider 13 is trapezoidal. A slide groove 14 is provided on the cleaning guard plate 5 located on the outer side of the light-transmitting plate 4. The slide groove 14 and the slider 13 cooperate with each other, so that the additional guard plate 6 can slide freely on the cleaning guard plate 5.

[0032] Furthermore, the height of the cleaning guard plate 5 is 0.55 times the height of the light-transmitting plate 4, and the height of the additional guard plate 6 is 0.5 times the height of the light-transmitting plate 4. Therefore, when the additional guard plate 6 and the cleaning guard plate 5 completely cover the light-transmitting plate 4, there is also a connecting portion between the cleaning guard plate 5 and the additional guard plate 6.

[0033] Furthermore, the cleaning guard plate 5 movably connected to the additional guard plate 6 is provided with first grooves 15 on both upper and lower sides, and the outer side of the additional guard plate 6 is provided with second grooves 16, so as to facilitate the operation of sliding the cleaning guard plate 5 and the additional guard plate 6 up and down.

[0034] In other embodiments, in order to ensure the sealing of the observation window assembly, sealing strips 18 are fixedly installed on both sides of the inner and outer through grooves 8 and on both sides of the connecting grooves 9. The sealing strips 18 are composed of two groups of silicone pads and the two groups of sealing strips 18 are interference fit. Furthermore, the connecting plate 11 passes through the two groups of sealing strips 18 and is interference fit with the sealing strips 18. In some embodiments, positioning sliders 17 are fixedly installed on the front and rear sides of the connecting frame 10. The positioning sliders 17 can slide up and down in the inner and outer through grooves 8 to improve the sliding stability of the connecting frame 10. The positioning sliders 17 also pass between the corresponding two groups of sealing strips 18 and are interference fit with the sealing strips 18. When the connecting frame 10 slides up and down, the connecting plate 11 shuttles up and down between the two groups of sealing strips 18, and the elastic force of the sealing strips 18 is used to ensure that the connecting plate 11 can slide normally while being sealed.

[0035] In other embodiments, when it is not necessary to keep the inner side of the light-transmitting plate 4 clean, only the cleaning guard plate 5 is installed in front of the light-transmitting plate 4, and the cleaning guard plate 5 behind the light-transmitting plate 4 does not need to be installed.

[0036] The technical solution provided by the utility model also includes a distribution cabinet, which includes the above-mentioned observation window assembly of the distribution cabinet, as well as a cabinet body 1 and a cabinet door 2. The front of the cabinet body 1 is open, and the cabinet door 2 is movably installed in the front of the cabinet body 1 through a hinge. The cabinet door 2 is provided with a mounting groove 7, and the window frame 3 in the observation window assembly of the distribution cabinet is fixedly installed in the mounting groove 7.

[0037] Working principle of the utility model: For the protection and cleaning of large observation windows, a connecting frame 10 that can slide up and down along the window frame 3 is movably installed on both sides of the window frame 3, and then a cleaning guard plate 5 is set on the front side of the light-transmitting plate 4 and fixedly connected to the connecting frame 10, and then a brush edge 12 that can clean the light-transmitting plate 4 is fixedly installed on the side of the cleaning guard plate 5 close to the light-transmitting plate 4. When the cleaning guard plate 5 slides up and down, the light-transmitting plate 4 is cleaned and protected by the cleaning guard plate 5. In order to further improve the protection range, an additional guard plate 6 that slides up and down is also movably installed on the cleaning guard plate 5. The additional guard plate 6 can overlap or unfold on the outside of the cleaning guard plate 5, and after unfolding, it protects the unprotected part of the cleaning guard plate 5.

[0038] If the inside of the light-transmitting plate 4 also needs to be cleaned, the connecting frame 10 can pass through the front and back sides of the cabinet door 2, and a cleaning guard plate 5 fixedly connected to the connecting frame 10 is provided on the inside of the light-transmitting plate 4. The two groups of cleaning guard plates 5 slide synchronously to clean the inside and outside of the light-transmitting plate 4.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
