[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-10 This invention provides an electrical performance testing device, comprising a body 1, a support plate 2 movably mounted inside the body 1, a testing module 3 mounted on the upper end of the support plate 2, a support frame 4 fixedly connected to the upper end of the body 1, a hydraulic cylinder 5 fixedly connected to the support frame 4, and a fastener 6 mounted on the extended end of the hydraulic cylinder 5.

[0033] The fastener 6 comprises a gas pump 7 fixedly connected with the movable end of the hydraulic cylinder 5, and a fastening unit is arranged at the bottom of the gas pump 7. The fastening unit comprises a support A 8 fixedly connected with the bottom of the gas pump 7, and a rotating shell 10 is screwed at the corners of the support A 8. The rotating shell 10 is screwed between the support A 8 and a support B 9, and a linear push rod 11 is movably arranged in the rotating shell 10. The support A 8 is provided with an orientation changing unit for changing the position of the head of the rotating shell 10, and the orientation changing unit comprises an adjustable rod 13. The support A 8 is also provided with a length adjusting unit for changing the length of the linear push rod 11 in the rotating shell 10, and the length adjusting unit comprises a motor 16. The head of the linear push rod 11 is provided with a silica gel suction nozzle 12, and a metal pipe is connected to the top of the silica gel suction nozzle 12. The metal pipe is connected to the gas pump 7 through a hose.

[0034] Referring to Figures 6-8 The orientation changing unit on the support A 8 comprises an adjustable rod 13, which comprises a fixed end fixedly connected with the support A 8 and a variable end capable of reciprocating. The variable end of the adjustable rod 13 is fixedly connected with an adapter seat 14, and the upper end and the lower end of the adapter seat 14 are fixedly connected with guide tables 15. The axes of the two guide tables 15 coincide. The rotating shell 10 is fixedly connected with a rotating table 101 on the side far away from the silica gel suction nozzle 12. The rotating table 101 on each of the pair of rotating shells 10 on one side of the support A 8 is respectively located on the vertical side of the rotating shell 10, so that the rotating table 101 can rotate smoothly. A strip-shaped opening 102 is reserved on the rotating table 101. The pair of guide tables 15 assembled on the upper end and the lower end of the adapter seat 14 are movably arranged in the corresponding strip-shaped openings 102. When the guide tables 15 move along the adjustable rod 13, the pair of guide tables 15 on the adapter seat 14 are movably arranged in the vertical strip-shaped openings 102. Since the rotating shell 10 is screwed between the support B 9 and the support A 8, the rotating shell 10 can rotate under the drive of the guide tables 15 when the guide tables 15 move. The length of the adjustable rod 13 can be controlled to realize the control of the opening size of the pair of rotating shells 10 on one side of the support A 8.

[0035] Referring to Figures 4-8, the bracket A8 and the bracket B9 are respectively provided with guide openings A81 and B91, the guide tables 15 on both sides of the adapter seat 14 are respectively movably arranged in the corresponding guide openings A81 and B91, the guide tables 15 are matched with the guide openings A81 and B91, and the guide tables 15 are also matched with the strip-shaped openings 102, the guide tables 15 respectively pass through the bracket A8 and the bracket B9, and one side of the guide tables 15 is fixedly connected with a protrusion for limiting the vertical movement of the guide tables 15, the edge of the protrusion is located outside the edge of the guide table 15, and the protrusion is respectively matched with the wall surface of the bracket B9 and the bracket A8, the guide structures on the bracket B9 and the bracket A8 can enable the adapter seat 14 to stably move along the changed orientation of the adjustable rod 13, so that the moving orientation of the adjustable rod 13 is prevented from being deviated due to the influence of the rotating table 101 during the change, and the pair of rotating tables 101 on the same side of the bracket A8 are arranged opposite to each other, the linkage rod 19 and the change rod 20 are located between the rotating tables 101 with different heights, and during the rotation of the rotating table 101, the change rod 20 and the linkage rod 19 change along the longitudinal direction of the bracket A8, so that the change rod 20 and the linkage rod 19 are prevented from being blocked between the rotating tables 101 during the rotation of the rotating shell 10 to change the opening size.

[0036] With reference to Figures 6-10 , the rotating shell 10 is provided with a traction rod 22 for traction of the linear push rod 11, one side of the traction rod 22 passes through the rotating shell 10 and is connected with the change rod 20 through the adapter 21, the change rod 20 is movably arranged in the linkage rod 19, the change rod 20 cannot rotate in the linkage rod 19, the change rod 20 can be traction-rotated through the linkage rod 19, the side of the linkage rod 19 is fixedly connected with the rotating part of the motor 16, the motor 16 is movably arranged on the bracket A8 along the longitudinal direction of the bracket A8, the change rod 20 is driven to rotate through the motor 16, the clockwise and counterclockwise rotation of the change rod 20 can change the length of the linear push rod 11 moving out of the rotating shell 10, the change rod 20 drives the traction rod 22 to rotate through the adapter 21, the traction rod 22 is a lead screw, and the linear push rod 11 is arranged with a change seat which is screwed with the traction rod 22 in the rotating shell 10, so that the length of the linear push rod 11 moving out of the rotating shell 10 can be changed when the traction rod 22 rotates.

[0037] With reference to Figures 6-10The bracket A8 has slide rails 18 installed longitudinally on both sides of the adjustable rod 13. A movable frame 17 is movably mounted on the slide rails 18, and a motor 16 is mounted on the movable frame 17. The motor 16 is a dual-shaft motor, and both shafts are fixedly connected to the linkage rod 19. When the rotating housing 10 rotates away from each other, the traction rod 22 in the rotating housing 10, mounted at the joint 21, moves longitudinally along the bracket A8, slowly moving towards a position farther from the center of the bracket A8. At this time, the movable bar 20 mounted on the joint 21 and the linkage rod 19 are pulled together and change position along the longitudinal direction of the bracket A8 under the changing state of the joint 21. The linkage rod 19 will move along the central axis, automatically adapting to the sum of the spans of the variable bar 20 and the linkage rod 19, to adapt to the distance between the connector 21 and the motor 16. During the rotation of the rotating housing 10 to change the opening size, the motor 16 can move along the slide 18 to change its orientation, so as to ensure that the traction rod 22 rotates smoothly. When the linkage rod 19 itself is long enough, it ensures that the linkage rod 19 moves smoothly along the longitudinal direction of the bracket A8. The variable platform is installed on the side of the linkage rod 19 that is far from the motor 16. The variable platform can be moved and installed in the groove on the bracket A8, and the groove is set directly opposite the slide 18.

[0038] Reference Figures 1-12 The bottom of the silicone nozzle 12 is connected to the silicone cylinder 24 via the assembly table 23. The bottom of the silicone nozzle 12 is higher than the bottom of the silicone cylinder 24. A through-hole is reserved in the center of the lower end of the silicone cylinder 24. During the fastening of the electrical equipment, the silicone cylinder 24 is in contact with the surface of the electrical equipment beforehand. When the silicone cylinder 24 is compressed, the air ejected can clean the particles at the fastening point of the electrical equipment outward, thereby ensuring the stability of the silicone nozzle 12 in fastening the electrical equipment.

[0039] Reference Figure 4 , Figure 5 , Figure 11 and Figure 12 Several obliquely arranged support strips 25 are evenly installed circumferentially at the lower end of the silicone tube 24. After the support strips 25 touch the surface of the electrical equipment, the silicone tube 24 is compressed and slowly approaches the lower end of the silicone tube 24. Because the support strips 25 are obliquely installed at the lower end of the silicone tube 24, after contacting the surface of the electrical equipment, the silicone tube 24 is compressed and exhausts air outward. The area where the support strips 25 touch the wall of the electrical equipment will slowly change, thereby changing the position on the wall of the electrical equipment. This can prevent the support platform from hindering the air from carrying away particulate matter. The contact between the support strips 25 and the wall of the electrical equipment allows the air discharged by the silicone tube 24 to have a better range of movement, thereby enhancing the dust removal function.

[0040] Reference Figure 4 , Figure 5 , Figure 11 and Figure 12The assembly table 23 is fixed on the upper end of the silica gel cylinder 24 and the inner surface of the silica gel suction nozzle 12 in a circumferential uniform manner, and a through groove is reserved between the assembly tables 23, which is used to connect the silica gel suction nozzle 12 and the metal pipe, so that the metal pipe can smoothly discharge the gas in the silica gel suction nozzle 12 when the silica gel cylinder 24 is compressed, and the silica gel cylinder 24 ensures that the silica gel suction nozzle 12 can operate under compression. The elastic member is arranged in the silica gel cylinder 24, and when the silica gel cylinder 24 is compressed, the elastic member is also compressed. When the silica gel suction nozzle 12 is separated from the wall surface of the electrical equipment, the deformation force of the elastic member makes the silica gel cylinder 24 quickly return to the original position. The elastic member in the silica gel cylinder 24 accelerates the return of the silica gel cylinder 24.

[0041] In use, the body 1 is filled with water, the electrical equipment is placed at the fastener 6, the adjustable rod 13 is extended or retracted, the rotating shell 10 on both sides of the support A8 is rotated to change the opening size, and the motor 16 on the support A8 is operated to sequentially drive the traction rod 22 through the linkage rod 19, the variable bar 20 and the joint 21, change the length of the straight push rod 11 extending in the rotating shell 10, and change the position of the straight push rod 11 to the appropriate position, thereby realizing the change of the position of the silica gel suction nozzle 12, ensuring that the electrical equipment of various shapes and specifications can be fastened, reducing the limitations of the device, and moving the support A8 downward after the support A8 is opposite to the electrical equipment during fastening of the electrical equipment. The silica gel cylinder 24 is first attached to the wall surface of the electrical equipment to remove dust from the wall surface of the electrical equipment, so that the particles on the wall surface of the electrical equipment at the silica gel suction nozzle 12 are cleaned, ensuring the fastening reliability of the silica gel suction nozzle 12 to the electrical equipment. The hydraulic cylinder 5 is extended to contact the electrical equipment and the detection module 3 to perform detection, and the detection module 3 can be moved to different water levels for detection under the pushing of the hydraulic cylinder 5, which enriches the detection data and improves the detection convenience of the equipment.

Those skilled in the art should understand that the present application is not limited to the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
