[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] A test device for an outdoor pole-mounted vacuum circuit breaker, which tests the outdoor pole-mounted vacuum circuit breaker. As Figure 1 shown, the test device includes a machine base 1, on which two side frames 2 are slidably arranged. The two side frames 2 are symmetrically installed on the machine base 1. A detection member 3 is slidably installed on the machine base 1, and the detection member 3 is located between the two side frames 2. Symmetrically distributed supporting members 5 are fixedly installed on the machine base 1, and a vacuum circuit breaker 4 is fixed on the supporting member 5. The vacuum circuit breaker 4 is placed on the supporting member 5.

[0042] As Figure 2 shown, the vacuum circuit breaker 4 includes an operation box 43, on which an array of insulators 41 are fixedly arranged, and conductive sheets 42 are fixedly installed on the insulators 41.

[0043] As Figure 3 shown, the machine base 1 includes a base 11, on which a first motor 13 is fixedly arranged. The output end of the first motor 13 is fixedly connected to a double-headed lead screw 12. A first synchronous pulley 15 is fixedly arranged on the double-headed lead screw 12. A support frame 14 is fixedly installed on the machine base 1. The double-headed lead screw 12 penetrates through the support frame 14. A horizontal shaft 16 is rotatably arranged in the support frame 14. A second synchronous pulley 161 is fixedly arranged on the horizontal shaft 16. A synchronous belt 162 is fixedly connected between the second synchronous pulley 161 and the first synchronous pulley 15. Through the conduction of the synchronous belt 162 between the second synchronous pulley 161 and the first synchronous pulley 15, the second synchronous pulley 161 and the first synchronous pulley 15 rotate synchronously.

[0044] A first gear 163 is fixedly arranged on the horizontal shaft 16. A top plate 17 is fixedly arranged on the support frame 14. A guide hole 18 is formed on the top plate 17. A first spring 19 is fixedly arranged on the top plate 17. The first spring 19 is symmetrically fixed below the top plate 17 and is fixedly connected to the upper part of the supporting member 5.

[0045] As Figures 3 - 10As shown, on both sides of the support frame 14, there are sliding support members 5. On the support member 5, there is a fixed support claw 51. Below the support claw 51, there is an inclined side 52. On the support claw 51, there is a notch 53. Inside the notch 53, there is a rotatable retaining claw 55. On one side of the retaining claw 55, there is a torsion spring 54 installed between the notch 53 and the retaining claw 55. When the retaining claw 55 is in the vertical state shown in the figure, at this time the torsion spring 54 is in a twisted state. In the vertical state, the inner side of the retaining claw 55 fits against the inner wall of the notch 53 and can resist the operation box 43 on the support claw 51.

[0046] Below the retaining claw 55, there is a fixed push rod 56. On one side of the push rod 56, there is a rotating rod 57. The rotating rod 57 is rotatably installed below the support claw 51. Below the support claw 51, there is a fixed motor two 58. The output end of the motor two 58 is fixedly connected to the rotating rod 57 to control the rotation of the rotating rod 57. When the rotating rod 57 rotates to limit the support claw 51 and keep the support claw 51 in a vertical state to block the vacuum circuit breaker 4. When the rotating rod 57 rotates upward, the torsion spring 54 will release elastic force, causing the retaining claw 55 to rotate from the vertical state towards the horizontal direction. During this process, the push rod 56 and the rotating rod 57 are in stable contact, and then the blocking of the retaining claw 55 is released, facilitating the loading and unloading operations of the vacuum circuit breaker 4.

[0047] On the side frame 2, there is a threaded hole 21 which is threadedly connected to the double-headed lead screw 12. On the side frame 2, there is a fixed support plate 22. On the support plate 22, there is an inclined plane 23 which is slidably connected to the inclined side 52 to push the support member 5 to move upward along the side wall of the support frame 14, compressing the first spring 19. On the side frame 2, there is a fixed mounting plate 24. On the side frame 2, there is a fixed horizontal slide 25. On the horizontal slide 25, there are symmetrically distributed moving blocks 26 sliding. On the outside of the moving block 26, there is a fixed connection to the second spring 27. One end of the second spring 27 is fixedly connected to the end of the horizontal slide 25.

[0048] On one side of the horizontal slide 25, there is a fixed guide rail 251. On the guide rail 251, there is a sliding mounting block 29. 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. At the other end of the mounting block 29, there is a fixed L-shaped rod 6. The L-shaped rods 6 on the two side frames 2 are arranged in a staggered manner. And on one side of the mounting block 29, there is a fixed connection frame 291. On the connection frame 291, there is a fixed clamping block 292. The clamping blocks 292 on the two side frames 2 clamp the two ends of the vacuum circuit breaker 4.

[0049] An opening groove is provided between two mounting plates 24. The detecting member 3 is vertically slidable within the opening groove. A sliding groove 20 is formed on the mounting plate 24. A mounting seat 201 is slidably disposed within the sliding groove 20. A column 202 is fixedly provided on the mounting seat 201. A first cylinder 203 is provided on one side of the mounting seat 201. The first cylinder 203 is fixedly mounted on the mounting plate 24, and the output end of the first cylinder 203 is fixedly connected to a flat plate 204. An S-shaped arc groove 205 is formed on the flat plate 204. The column 202 is slidably mounted within the S-shaped arc groove 205.

[0050] When the flat plate 204 horizontally slides, the column 202 moves along the S-shaped arc groove 205, which can control the reciprocating movement of the mounting seat 201 along the sliding groove 20. A fixing rod 207 is fixedly provided on the mounting seat 201. One end of the fixing rod 207 is fixedly connected to a detecting block 209. An impact block 208 is slidably disposed on the fixing rod 207. A convex rod (not shown in the figure) is fixedly connected below the impact block 208. A third motor 206 is fixedly mounted on the mounting seat 201. The output end of the third motor 206 is fixedly connected to a driving shaft 2010. One end of the driving shaft 2010 is fixedly mounted with a round rod 2011. A threaded ring groove 2012 is formed 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, forming an annular path for guiding the convex rod.

[0051] 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 along the direction of the fixing rod 207, and the impact block 208 impacts the detecting block 209. When the round rod 2011 continues to rotate 180 degrees, the convex rod slides reversely to the initial position along the direction of the fixing rod 207. It can be seen that when the round rod 2011 continuously rotates, the impact block 208 reciprocates on the fixing rod 207, intermittently impacting the detecting block 209.

[0052] As Figures 11 - 14 shown, the detecting member 3 includes a moving frame 31. The moving frame 31 is slidably mounted within the guiding hole 18. A first rack 32 is formed on the moving frame 31. The first rack 32 meshes with the first gear 163. By rotating the first gear 163, the up and down movement of the first rack 32 can be controlled. A third cylinder 33 is fixedly mounted on the top of the moving frame 31. The output end of the third cylinder 33 is fixedly connected to a trapezoidal block 34. The two inclined sides of the trapezoidal block 34 are symmetrically arranged, and the two inclined sides of the trapezoidal block 34 are respectively slidably connected to the ends of two L-shaped rods 6.

[0053] A connecting block 35 is fixedly provided on the moving frame 31. A cross plate 36 is fixedly installed below the connecting block 35. Three top blocks 37 are provided on the cross plate 36. One of the top blocks 37 is fixedly installed on the cross plate 36, and the other two top blocks 37 are symmetrically slidably arranged on the cross plate 36. Springs three 38 are fixedly provided on one side of the two top blocks 37. One end of the spring three 38 is fixedly connected to the cross plate 36, and racks two 377 are staggeredly arranged on the two top blocks 37.

[0054] A mounting shaft 371 is rotatably provided below the top block 37. An oscillating arm 375 is fixedly provided on the mounting shaft 371. A conductive rod 376 is fixedly provided on the oscillating arm 375. A gear two 372 is fixedly provided at one end of the mounting shaft 371. A motor four 373 is fixedly installed on the top block 37. The output end of the motor four 373 is fixedly connected to a gear three 374. The gear three 374 meshes with the gear two 372.

[0055] The rotation of the gear three 374 is controlled by the motor four 373, so that the gear two 372 rotates, the oscillating arm 375 is controlled to rotate, and the conductive rod 376 is brought into contact with the conductive sheet 42. Then, the voltmeter is manually operated to be connected to the contact sheet on the upper side of the insulator, and the electrical conductivity of the insulator 41 is detected.

[0056] A gear four 391 is arranged between the two racks two 377. A motor five 39 is fixedly provided 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 meshes between the two racks two 377. By controlling the gear four 391, the two racks two 377 move towards each other, and the two slidably arranged top blocks 37 move towards each other. The spring three 38 is gradually compressed, thereby controlling the distance between the three top blocks 37 to be shortened, so as to match the insulators with different distances on the vacuum circuit breaker.

[0057] The working principle is as follows:

[0058] When the testing device is in the initial state, the position of the supporting member 5 is relatively low, which is convenient for placing the outdoor pole-mounted vacuum circuit breaker on the supporting member 5. Then, by starting the motor one 13, the double-headed lead screw 12 is controlled to rotate, so that the two side frames 2 move towards each other. The supporting plates 22 on the two side frames 2 support the hypotenuse 52. As the two side frames 2 approach each other, the height of the supporting member 5 is gradually increased until the position of the vacuum circuit breaker is raised to the position of the two clamping blocks 292.

[0059] During this process, through the synchronous belt 162, the synchronous wheel one 15 is transmitted to the synchronous wheel two 161, driving the cross shaft 16 and the gear one 163 to rotate. The gear one 163 meshes with the rack one 32, driving the moving frame 31 to move downward, reducing the height of the cross plate 36, and the cross plate 36 gradually approaches the top of the insulator 41.

[0060] Then, the cylinder three 33 is used to control the trapezoidal block 34 to move downward, so that the trapezoidal block 34 is inserted between the two L-shaped rods 6. The trapezoidal block 34 blocks the two L-shaped rods 6, causing the two connecting frames 291 to move towards each other, and the clamping blocks 292 gradually approach 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 second spring 27 pulls the moving block 26, so that the connecting rod 28 maintains a pulling force on the mounting block 29, thereby realizing that the end of the L-shaped rod 6 stably fits on the inclined side of the trapezoidal block 34. After clamping by the clamping blocks 292, the rotating rod 57 is used to push the pawl 51 to rotate, and the pawl 51 is used to block the vacuum circuit breaker 4.

[0061] Then, the motor four 373 is used to control the rotation of the gear three 374, 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 an electric current through a wire. At this time, the insulator can be detected.

[0062] Finally, the vacuum circuit breaker is impacted by moving the detection block 209 to detect the impact resistance strength and product strength of the circuit breaker. After the detection is completed, the detection block 209 is moved to fit on the surface of the vacuum circuit breaker, and then by controlling the rotation of the round rod 2011, the impact block 208 intermittently moves towards the detection block 209 to impact the detection block 209, generating vibrations on the detection block 209. When the vibrations are transmitted to the vacuum circuit breaker, the seismic resistance strength of the vacuum circuit breaker product is thus detected.
