[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1:

[0037] See also Figures 1 to 8 As shown, an electrical testing device for testing electrical equipment includes:

[0038] Support shell 1;

[0039] A supporting mechanism 2 is installed inside the supporting shell 1, two locking mechanisms 3 are embedded in the upper part of the outer wall of the supporting shell 1, and a cooling mechanism 4 is installed on the lower part of the outer wall of the other side of the supporting shell 1;

[0040] The supporting mechanism 2 includes an adjusting screw 21, a driver 22, a supporting rod 23, a locking groove 24 and an electrical testing mechanism 25. The adjusting screw 21 is mounted on the bottom inner wall of the supporting shell 1 through a bearing, the driver 22 is mounted on the bottom end of the adjusting screw 21, the supporting rod 23 is mounted on the outer surface of the adjusting screw 21, a plurality of locking grooves 24 are provided, and the plurality of locking grooves 24 are respectively opened at both ends of the supporting rod 23, and the electrical testing mechanism 25 is mounted on the top end of the supporting rod 23.

[0041] Depend on Figures 1 to 5As can be seen, handles 5 are installed at the lower part of both ends of the support shell 1, and anti-slip sleeves 6 are installed in the middle of the outer surface of the two handles 5. A controller 7 is installed at the lower part of the outer wall of the support shell 1, and an inlet and outlet 8 is opened in the middle of the top of the support shell 1.

[0042] The electrical testing mechanism 25 includes a support frame 251, an electric turntable 252, a drive motor 253, an adjustment frame 254, a camera 255 and an electroscope 256. The electric turntable 252 is installed at the bottom end of the support frame 251, and the bottom end of the electric turntable 252 is installed at the top of the support rod 23. The drive motor 253 is installed on the upper part of the outer wall of the support frame 251. The adjustment frame 254 is installed between the inner walls on both sides of the support frame 251 through bearings. The camera 255 is installed at the top of the adjustment frame 254, and the electroscope 256 is installed on the inner wall of the adjustment frame 254.

[0043] As can be seen from the above, when it is necessary to conduct electrical testing on electrical equipment at heights, the operator's operating process becomes simple and efficient. Only the button of the controller 7 needs to be touched to start the driver 22. The driver 22 drives the adjustment screw 21 to start rotating, and this rotation is then converted into a stable upward movement of the support rod 23, supporting the entire electrical testing mechanism 25 to slowly rise. As the support rod 23 gradually rises, the support frame 251 and the electrical tester 256 it carries also rise gracefully. This rising process is not only smooth and smooth but also speed-controllable, ensuring that the electrical tester 256 can accurately reach the required high-altitude testing position. This innovative design is inconsistent with the traditional high-altitude electrical testing method. Operators no longer need to take the risk of climbing to a high place for testing, which greatly simplifies the testing process, shortens the testing time, and significantly reduces the safety risks brought by working at heights. What is more advanced is that the camera 255 can capture images of electrical equipment in real time and transmit these high-definition images The information is transmitted to the controller 7 in real time, and the operator can accurately move the electroscope 256 to the detection position through the clear image on the screen, which improves the accuracy of the operation and further enhances the safety of the operator. In addition, through the controller 7, the operator can also control the electric turntable 252 and the drive motor 253 in sequence to achieve flexible adjustment of the electroscope 256 in the horizontal and tilt directions. The activation of the electric turntable 252 can drive the support frame 251 to rotate smoothly, thereby easily adjusting the horizontal angle of the electroscope 256; and the activation of the drive motor 253 can drive the adjustment frame 254 to rotate flexibly, thereby achieving precise adjustment of the tilt angle of the electroscope 256. This flexible and changeable design enables the electroscope mechanism 25 to easily cope with electrical equipment of various shapes and sizes, greatly broadens its scope of application, and meets the needs of various complex electrical equipment detection. The electroscope mechanism 25 can provide strong protection for the safe operation of electrical equipment with its excellent performance and flexibility.

[0044] Specifically, refer to Figures 1 to 5As shown, the electric turntable 252, the driving motor 253, the camera 255, the electroscope 256 and the driver 22 are all electrically connected to the controller 7, the adjustment frame 254 is configured as a Y-shaped structure, and the lower portion of the outer surface of the support rod 23 is configured as a convex structure.

[0045] As can be seen from the above, these devices can be controlled by the electrical connection controller 7 to achieve comprehensive adjustment of the entire electroscope device. The Y-shaped structure makes the adjustment frame 254 have better stability and flexibility, which makes it easier for the adjustment frame 254 to support and adjust the position of the camera 255 or the electroscope 256, and prevents the support rod 23 from detaching from the support shell 1.

[0046] Example 2:

[0047] refer to Figure 6 As shown, the locking mechanism 3 includes a mounting frame 31, a positioning ridge 32, a rotating shaft 33, a rotating frame 34, a locking pawl 35 and a torsion spring 36. The mounting frame 31 is mounted on the inner wall of the support shell 1, the positioning ridge 32 is mounted on the bottom inner wall of the mounting frame 31, the rotating shaft 33 is mounted between the inner walls on both sides of the mounting frame 31 through a bearing, the rotating frame 34 is mounted at one end of the rotating shaft 33, the locking pawl 35 is mounted in the middle of the outer surface of the rotating shaft 33, and two torsion springs 36 are provided, and the two torsion springs 36 are respectively mounted on both sides of the outer surface of the rotating shaft 33.

[0048] As can be seen from the above, once the support rod 23 is accurately adjusted to the required position, the elastic force of the torsion spring 36 will be exerted in time to push the locking pawl 35 to rotate until it is tightly engaged with the locking groove 24 on the support rod 23. This stable locking mechanism is like a solid barrier, firmly fixing the support rod 23, greatly improving its stability and reliability during use. When the support rod 23 is adjusted to the highest position, this locking mechanism will be intelligently released. At this time, the locking pawl 35 will no longer remain engaged with the locking groove 24. The operator only needs to simply pinch the rotating frame 34 and gently turn the rotating shaft 33, and the locking pawl 35 will smoothly move away from the support rod 23 to achieve complete disengagement. This design allows the support rod 23 to be easily and smoothly retracted into the interior of the support shell 1 without hindrance, providing great convenience for subsequent storage and transportation.

[0049] Preferably, reference Figure 6 As shown, the locking pawl 35 is provided with two protrusions that contact the torsion spring 36 , and the locking pawl 35 is engaged with the locking groove 24 , and the rotating frame 34 is provided with a herringbone structure.

[0050] As can be seen from the above, the protrusion on the locking pawl 35 cooperates with the torsion spring 36 to realize the automatic resetting and locking function of the locking pawl 35, ensuring that the support rod 23 can be firmly locked after being adjusted into place to prevent it from moving during use, making it convenient to rotate the rotating shaft 33 through the rotating frame 34.

[0051] Example 3:

[0052] refer to Figure 7 and Figure 8 As shown, the cooling mechanism 4 includes a fixing seat 41, a fixing groove 42, a dry powder tank 43, a carbon dioxide tank 44 and a connecting pipe 45. The fixing seat 41 is mounted on the outer wall of the other side of the supporting shell 1. Two fixing grooves 42 are provided. Both fixing grooves 42 are opened at the top of the fixing seat 41. The dry powder tank 43 is installed in one fixing groove 42, and the carbon dioxide tank 44 is installed in the other fixing groove 42. The connecting pipe 45 is installed between the tops of the dry powder tank 43 and the carbon dioxide tank 44.

[0053] A delivery pipe 46 is installed at the top of the connecting pipe 45 , a cooling nozzle 47 is installed at the other end of the delivery pipe 46 , a fixing block 48 is installed at the top of the cooling nozzle 47 , and the top of the fixing block 48 is installed at the bottom end of the electroscope 256 .

[0054] As can be seen from the above, the cooling nozzle 47 can be firmly mounted on the electroscope 256 through the connection between the fixing block 48 and the electroscope 256. This design ensures that the cooling nozzle 47 can move accurately and synchronously with the movement of the electroscope 256. Once the electrical equipment overheats or requires emergency fire extinguishing, the operator only needs to operate the controller 7 to open the preset solenoid valve on the connecting pipe 45. At this time, the high-efficiency dry powder stored in the dry powder tank 43 or the high-pressure carbon dioxide in the carbon dioxide tank 44 can be quickly and accurately introduced into the delivery pipe 46 through the connecting pipe 45. Then, these cooling media will be evenly sprayed at an appropriate speed and pressure through the cooling nozzle 47. It is shot onto the target electrical equipment, quickly achieving cooling or fire extinguishing effects, thereby greatly improving the safety of the work site. What is more worth mentioning is that the system is designed with operational flexibility and practicality in mind. By separately controlling the two independent solenoid valves on the connecting pipe 45, the operator can freely choose to use only dry powder or only carbon dioxide for cooling or fire extinguishing operations. This humanized design not only increases operational flexibility, but also enables the operator to flexibly select the most suitable cooling material according to the actual application scenario, the type of electrical equipment and the specific needs of the emergency situation. This design not only broadens the application scope of the system, but also further enhances its ability to cope with various complex situations.

[0055] Preferably, reference Figure 7 and Figure 8As shown, the delivery pipe 46 is configured as a long hose, the connecting pipe 45 is configured as a Y-shaped structure, and two solenoid valves electrically connected to the controller 7 are provided at the lower portion of the outer surface of the connecting pipe 45 .

[0056] As can be seen from the above, the design of the long hose enables the delivery pipe 46 to flexibly adapt to different position and angle requirements, ensuring that the dry powder and carbon dioxide can accurately reach the target area. The Y-shaped structure enables the connecting pipe 45 to simultaneously connect the dry powder tank 43 and the carbon dioxide tank 44, and the solenoid valve is used to control the flow of the medium.

[0057] Application examples:

[0058] This design is mainly used in the electrical testing environment of power systems and industrial and mining enterprises, especially in those occasions where electrical testing is required for electrical equipment installed in complex and changeable locations and often at high positions. In substations, electrical equipment is often installed at high positions for the sake of efficiency and safety of power transmission and distribution. In the electrical workshops of industrial and mining enterprises, there are a large number of electrical equipment, which may be distributed in various heights and positions in a staggered manner, which undoubtedly increases the difficulty and complexity of electrical testing.

[0059] In order to meet these challenges, the present design cleverly sets up a supporting mechanism 2, which can stably support the electroscope 256 and can easily cope with electrical equipment at different heights through flexible adjustment. The operator only needs to simply adjust the height and angle of the supporting mechanism 2 to achieve accurate detection of electrical equipment at high places, thereby greatly improving the efficiency and safety of the detection. In addition, the present design is also carefully equipped with a locking mechanism 3. The main function of this mechanism is to lock and fix the supporting mechanism 2 to prevent it from shaking or displacement due to external forces during operation. Through the stabilizing effect of the locking mechanism 3, the stability of the supporting mechanism 2 is significantly improved, thereby ensuring that the electroscope 256 can always remain stable during the detection process. The fixed position not only avoids the detection error caused by shaking or displacement, but also effectively eliminates the potential safety hazards. What is more considerate is that the design also innovatively adds a cooling mechanism 4, which can spray dry powder, carbon dioxide and other media as needed to timely and effectively cool down or extinguish the electrical equipment. This design not only helps to prevent safety accidents such as equipment failure or fire due to overheating, but also can quickly carry out fire extinguishing operations when a fire really occurs in the equipment, thereby minimizing losses. In summary, the design, with its unique supporting mechanism 2, locking mechanism 3 and cooling mechanism 4, has successfully solved a series of difficult problems in electrical detection of power systems and industrial and mining enterprises, and provided a strong guarantee for the safe operation of electrical equipment.
