[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1

[0029] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a GIS equipment knife switch operating hole observation device, the device includes a light intake unit 100, including an observation cross bar 101, a light intake portion 102 arranged on the observation cross bar 101, and a supplementary light portion 104 connected to the light intake portion 102 through an observation straight rod 103;

[0030] The observation unit 200 includes an observation portion 201 disposed on the observation straight rod 103, and an insulating handle 202 disposed below the observation portion 201. The device integrates the light intake unit 100 and the observation unit 200, so that the staff can complete the functions of light supplement and knife switch position observation on the same device. Through the arrangement of the observation cross bar 101 and the observation straight rod 103, a stable structure is formed, which is convenient for the staff to hold and operate. The light intake portion 102 is arranged on the observation cross bar 101, so that external light enters the operating hole of the GIS equipment, thereby improving the brightness in the observation hole 201b. The light supplement portion 104 is connected to the light intake portion 102 through the observation straight rod 103, and can provide an additional light source in an environment with insufficient light, which is convenient for the staff to hold and operate. The operator can clearly see the position and status of the knife switch. The observation part 201 is arranged on the observation straight rod 103 and cooperates closely with the fill light part 104, so that the operator can adjust to a suitable viewing angle to observe the inside of the GIS equipment. The design of the insulating handle 202 not only provides a comfortable gripping point, but more importantly ensures the safety of the operator during operation. The insulating handle 202 is arranged below the observation part 201, which is convenient for the operator to adjust the observation angle and position while maintaining the stability of the operation. Whether in a small space or in an environment with insufficient light, the operator can clearly observe the inside of the equipment, and at the same time can reduce the time required for the operator to check the position of the knife switch of the GIS equipment, thereby improving work efficiency.

[0031] Among them, the light inlet part 102 includes a light inlet component 102a arranged on the observation cross bar 101, and a reflective component 102b connected to the light inlet component 102a. The light inlet component 102a is directly arranged on the observation cross bar 101, so that the light can directly enter the observation device, thereby improving the light collection efficiency and thus improving the visibility. The reflective component 102b is connected to the light inlet component 102a, and its function is to reflect the light so that the light can more effectively enter the operating hole of the GIS equipment, especially in a dark environment. Through the reflection effect of the reflective component 102b, the loss of light can be reduced, and the light intensity in the operating hole can be improved, so that the staff can observe the position and status of the knife switch more clearly, thereby reducing the risk of the staff working under low light conditions and improving the accuracy of the operation.

[0032] During use, the light intake part 102 and the fill light part 104 are connected through the observation straight rod 103 to ensure that all connections are firm and reliable. If the light on site is insufficient, turn on the light source of the fill light part 104, adjust the angle of the light intake component 102a to ensure that external light or fill light can smoothly enter the operating hole, adjust the reflective component 102b to reflect the light at the optimal angle to enhance the illumination in the operating hole. The staff holds the insulating handle 202, aligns the observation part 201 with the operating hole of the GIS equipment, observes the position and status of the knife switch through the observation part 201, and confirms whether the knife switch is correctly opened and closed. If necessary, the observation angle can be changed by adjusting the position on the observation straight rod 103 or the T-shaped connector 201a to observe the knife switch more clearly.

[0033] Example 2

[0034] Reference Figure 1-2 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the light inlet component 102a includes a light inlet hole 102a-1 arranged on the observation cross bar 101, and light-absorbing cotton 102a-2 arranged on the inner wall surface of the observation cross bar 101. The light inlet hole 102a-1 is the main channel for light to enter the device, allowing external light or light from the fill light part 104 to enter the observation device, and the light-absorbing cotton 102a-2 can absorb excess light and reduce glare and reflection inside the observation cross bar 101, thereby improving the uniformity and clarity of light in the observation hole 201b, enhancing the contrast between the knife switch position and the background, making the position and state of the knife switch easier to identify, and enabling the device to adapt to different light conditions, and providing better observation effects whether in strong light or weak light environments.

[0035] Compared with Example 1, further, the reflective component 102b includes a plane reflector 102b-1 arranged at a 45° angle at the corner where the observation cross bar 101 and the observation straight bar 103 are connected, and a diffuse reflection cotton 102b-2 arranged on the inner wall surface of the observation straight bar 103. The position and angle of the plane reflector 102b-1 can be adjusted to adapt to different observation angles and light conditions, thereby improving the flexibility and adaptability of observation. The diffuse reflection cotton 102b-2 can scatter light and reduce direct reflection of light, thereby providing more uniform lighting, reducing shadows and hot spots, making the position and status of the knife switch easier to identify, so that the staff can clearly observe the status of the knife switch under various light conditions.

[0036] Compared with Example 1, further, the fill light unit 104 includes a fill light component 104a disposed on the observation straight rod 103, and a lighting component 104b connected to the fill light component 104a. The fill light component 104a can provide an additional light source to enhance the illumination in the operating hole of the GIS equipment, especially in an environment with insufficient light. The function of the lighting component 104b is to further enhance or adjust the fill light effect to control and optimize the direction and intensity of the light. By using the fill light component 104a and the lighting component 104b in combination, the staff can more accurately control the direction and intensity of the light, ensuring that the light can accurately illuminate the key area of ​​the knife switch operating hole, and even under complex light conditions, it can provide sufficient lighting to help the staff clearly observe the status of the knife switch and improve the accuracy and safety of the operation.

[0037] Compared with Example 1, further, the fill light component 104a includes a concave reflector 104a-1 arranged inside the observation straight rod 103, and a transmission mirror 104a-2 arranged inside the observation straight rod 103. The concave reflector 104a-1 has a converging effect on light, and can focus the light emitted by the fill light to enhance the concentration and brightness of the light. The transmission mirror 104a-2 is arranged inside the observation straight rod 103 and is used in conjunction with the concave reflector 104a-1 to further adjust the direction and focal length of the light to ensure that the light can be more accurately irradiated into the knife switch operating hole, thereby improving the lighting effect. Through the cooperation of the concave reflector 104a-1 and the transmission mirror 104a-2, precise focusing and control of the light can be achieved. This design can improve lighting efficiency, especially in situations where space is limited or precise lighting is required, so that staff can obtain a clearer view of the knife switch position.

[0038] Compared with Example 1, further, the lighting component 104b includes a lighting lamp 104b-1 arranged in a parallel position to the concave reflector 104a-1, and a magnifying glass 104b-2 arranged in a vertical direction to the transmission mirror 104a-2. The light emitted by the lighting lamp 104b-1 is focused by the concave reflector 104a-1, and then further adjusted by the transmission mirror 104a-2 to ensure that the light is accurately irradiated into the knife switch operating hole of the GIS equipment. The magnifying glass 104b-2 is arranged in a vertical direction to the transmission mirror 104a-2. This design can provide additional magnification function without affecting the transmission of light, so that the staff can observe the subtle state of the knife switch more clearly. The combined use of the lighting lamp 104b-1 and the magnifying glass 104b-2 allows the staff to enlarge and observe specific parts of the knife switch while providing sufficient lighting, so that the staff can more accurately judge whether the knife switch has been correctly opened and closed, thereby improving the safety and accuracy of the operation.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3

[0041] Reference Figure 1-2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the observation part 201 includes a T-shaped connector 201a mounted on the observation straight rod 103, and an observation hole 201b arranged on the T-shaped connector 201a. The T-shaped connector 201a provides a stable structure for fixing and supporting the observation hole 201b, while allowing the observation part 201 to flexibly adjust its position and angle on the straight rod. The observation hole 201b is arranged on the T-shaped connector 201a, so that the observation hole 201b can be aligned with the knife switch operating hole, which is convenient for the staff to observe, and the observation hole 201b can be adjusted at different angles and directions to meet different observation needs. The design of the T-shaped connector 201a provides better flexibility and adjustability. The staff can easily adjust the direction of the observation hole 201b according to the actual observation angle and position requirements to obtain the best observation effect. At the same time, the design of the T-shaped connector 201a and the observation hole 201b is convenient for daily maintenance and cleaning, ensuring that the observation hole 201b always remains clear and is not affected by dust and dirt.

[0042] Compared with Example 2, further, the insulating handle 202 is a two-section telescopic insulating operating rod with a fixed length of 1m and a telescopic length of not less than 300mm, and the withstand voltage level of the insulating handle 202 is not less than 42kV. The insulating handle 202 can be adjusted in length according to the needs of the staff and on-site conditions, providing greater flexibility and adaptability. The telescopic design allows the insulating handle 202 to quickly adjust its length according to operational needs, providing convenience whether it is operating on the ground or when it needs to be extended to reach a higher position, including situations where space is limited or operation needs to be performed from a distance.

[0043] The withstand voltage rating of the insulated handle 202 is not less than 42kV, which means that even in a high voltage environment, workers can safely use the device, ensuring the safety of operation, reducing the safety risks of workers when working near high voltage equipment, and providing additional safety protection.

[0044] Compared with Example 2, further, the insulating handle 202 is hollow inside, and the top end is directly connected to the observation straight rod 103. At this time, the insulating handle 202 can also be used as an observation lens tube, which is convenient for the staff to observe the inside of the equipment.

[0045] The remaining structure is the same as that of Example 2.
