When the stopper 55 is in the vertical state shown in the figure, the torsion spring 54 is in a torsion state. In the vertical state, the inner side of the stopper 55 fits with the inner wall of the slot 53, so as to resist the operating box 43 on the supporting claw 51.

[0028] A push rod 56 is fixedly provided below the blocking claw 55, and a rotating rod 57 is provided on one side of the push rod 56.

A spring 27 is fixedly connected to the outer side of the moving block 26, and one end of the spring 27 is fixedly connected to the end of the horizontal slide 25.

[0030] A guide rail 251 is fixedly provided on one side of the horizontal slide 25, and a mounting block 29 is slidably provided on the guide rail 251. One end of the mounting block 29 is rotatably connected to two connecting rods 28. One end of the connecting rod 28 is rotatably connected to the mounting block 29, and the other end is rotatably connected to the moving block 26. An L-shaped rod 6 is fixedly installed on the other end of the mounting block 29. The L-shaped rod 6 on the two side frames 2 are staggered, and a connecting frame 291 is fixedly installed on one side of the mounting block 29. A clamping block 292 is fixedly installed on the connecting frame 291. The clamping blocks 292 on the two side frames 2 clamp the two ends of the vacuum circuit breaker 4.

[0031] An open groove is provided between the two mounting plates 24, and the detection member 3 is located in the open groove and slides vertically. A slide groove 20 is provided on the mounting plate 24, and a mounting seat 201 is slidably provided in the slide groove 20. A column 202 is fixedly provided on the mounting seat 201. A cylinder 203 is provided on one side of the mounting seat 201. The cylinder 203 is fixedly installed on the mounting plate 24, and a flat plate 204 is fixedly connected to the output end of the cylinder 203. An S-shaped arc groove 205 is provided on the flat plate 204, and the column 202 is slidably installed in the S-shaped arc groove 205.

[0032] When the flat plate 204 slides horizontally, the column 202 moves along the S-shaped arc groove 205, and can control the mounting seat 201 to reciprocate along the slide groove 20. A fixed rod 207 is fixed on the mounting seat 201, and one end of the fixed rod 207 is fixedly connected to a detection block 209. An impact block 208 is slidably provided on the fixed rod 207, and a convex rod is fixedly connected below the impact block 208, which is not shown in the figure. A motor 3 206 is fixedly installed on the mounting seat 201, and a drive shaft 2010 is fixedly connected to the output end of the motor 3 206. A round rod 2011 is fixedly installed on one end of the drive shaft 2010. A threaded ring groove 2012 is opened on the side wall of the round rod 2011. The paths of the threaded ring groove 2012 on both sides of the round rod 2011 are symmetrically arranged to form an annular path for guiding the convex rod.

[0033] The convex rod is slidably connected to the threaded ring groove 2012. When the round rod 2011 rotates 180 degrees, the convex rod slides from one end of the round rod 2011 to the other end of the round rod 2011 along the direction of the fixed rod 207, and the impact block 208 hits the detection block 209. When the round rod 2011 continues to rotate 180 degrees, the convex rod slides in the opposite direction to the initial position along the direction of the fixed rod 207. It can be seen that when the round rod 2011 continues to rotate, the impact block 208 moves back and forth on the fixed rod 207, intermittently impacting the detection block 209.

[0034] like Figure 11-Figure 14 As shown, the detection member 3 includes a moving frame 31, which is slidably installed in the guide hole 18. A rack 32 is provided on the moving frame 31, and the rack 32 is meshed with a gear 163. The gear 163 rotates to control the rack 32 to move upward and downward. A cylinder 33 is fixedly installed on the top of the moving frame 31, and a trapezoidal block 34 is fixedly connected to the output end of the cylinder 33. The two hypotenuses of the trapezoidal block 34 are symmetrically arranged, and the two hypotenuses of the trapezoidal block 34 are respectively slidably connected to the ends of the two L-shaped rods 6.

[0035] A connecting block 35 is fixedly provided on the movable frame 31, a horizontal plate 36 is fixedly installed below the connecting block 35, three top blocks 37 are provided on the horizontal plate 36, one of the top blocks 37 is fixedly installed on the horizontal plate 36, and the other two top blocks 37 are symmetrically slidably arranged on the horizontal plate 36, and a spring three 38 is fixedly provided on one side of the two top blocks 37, one end of the spring three 38 is fixedly connected to the horizontal plate 36, and rack two 377 are staggeredly arranged on the two top blocks 37.

[0036] A mounting shaft 371 is rotatably provided below the top block 37, a swing arm 375 is fixedly provided on the mounting shaft 371, a conductive rod 376 is fixedly provided on the swing arm 375, a gear 2 372 is fixedly provided at one end of the mounting shaft 371, a motor 4 373 is fixedly provided on the top block 37, a gear 3 374 is fixedly connected to the output end of the motor 4 373, and the gear 3 374 is meshed with the gear 2 372.

[0037] The motor 4 373 is used to control the rotation of the gear 3 374, so that the gear 2 372 is rotated, and the swing arm 375 is controlled to rotate, so that the conductive rod 376 is in contact with the conductive sheet 42, and then the voltmeter is manually operated to connect with the contact sheet on the upper side of the insulator to detect the conductive performance of the insulator 41.

[0038] A gear four 391 is arranged between the two rack twos 377, and a motor five 39 is fixedly arranged on the connecting block 35. The output end of the motor five 39 is fixedly connected to the gear four 391. The gear four 391 is engaged between the two rack twos 377. The two rack twos 377 are controlled to move toward each other by the gear four 391, so that the two sliding top blocks 37 move toward each other, and the spring three 38 is gradually compressed, thereby controlling the spacing between the three top blocks 37 to shorten, so as to match the insulators with different spacings on the vacuum circuit breaker.

[0039] Here’s how it works: When the test device is in the initial state, the position of the bracket 5 is relatively low, which makes it convenient to place the outdoor column vacuum circuit breaker on the bracket 5. Then, by starting the motor 13, the double-headed screw 12 is controlled to rotate, so that the two side frames 2 move toward each other, and the support plates 22 on the two side frames 2 support the bevel 52. As the two side frames 2 approach each other, the height of the bracket 5 is gradually increased until the position of the vacuum circuit breaker is increased to the position of the two clamping blocks 292.

[0040] During this process, the synchronous wheel 15 is transmitted to the synchronous wheel 2 161 through the synchronous belt 162, driving the horizontal shaft 16 and the gear 1 163 to rotate. The gear 1 163 engages with the rack 1 32, driving the movable frame 31 to move downward, lowering the height of the horizontal plate 36, and the horizontal plate 36 gradually approaches the top of the insulator 41.

[0041] Then, the trapezoidal block 34 is controlled to move downward by the cylinder 33, so that the trapezoidal block 34 is inserted between the two L-shaped rods 6, and the trapezoidal block 34 blocks the two L-shaped rods 6, so that the two connecting frames 291 move toward each other, and the clamping block 292 gradually approaches the vacuum circuit breaker 4 until the vacuum circuit breaker 4 is clamped. After clamping, the trapezoidal block 34 fixes the two L-shaped rods 6, and the spring 27 pulls the moving block 26, so that the connecting rod 28 maintains the pulling force on the mounting block 29, thereby achieving the end of the L-shaped rod 6 Stably fits on the hypotenuse of the trapezoidal block 34. After being clamped by the clamping block 292, the rotating rod 57 is used to push the claw 51 to rotate, and the claw 51 is used to block the vacuum circuit breaker 4.

[0042] Then, motor four 373 is used to control gear three 374 to rotate, driving the swing arm 375 to rotate until the conductive rod 376 is connected to the conductive sheet 42, and the end of the conductive rod 376 is connected to the current through the wire, at which time the insulator can be tested.

[0043] Finally, the vacuum circuit breaker is impacted by moving the detection block 209 to detect the impact resistance and product strength of the circuit breaker. After the detection is completed, the detection block 209 is moved to fit the surface of the vacuum circuit breaker, and then the impact block 208 is intermittently moved toward the detection block 209 by controlling the rotation of the round rod 2011 to impact the detection block 209, generating vibration on the detection block 209. When the vibration is transmitted to the vacuum circuit breaker, the seismic strength of the vacuum circuit breaker product is detected.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
