Description

Technical Field

[0002] Vacuum circuit breakers are circuit breakers in which both the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum. They have the advantages of small size, light weight, suitable for frequent operation, and arc extinguishing without maintenance. They can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. After the production of the circuit breaker is completed, the vacuum circuit breaker needs to be tested for withstand voltage to avoid the vacuum circuit breaker being of poor quality and affecting the later repair rate. The existing circuit breaker pressure detection device is usually a fixed device. When it needs to be moved to another location, it is usually hoisted and moved. This placement is time-consuming and labor-intensive. At the same time, when the circuit breaker is pressed by the pressure plate during pressure detection, it is easy to shake on the workbench, affecting the pressure detection effect. For this reason, we propose a convenient mobile detection device for vacuum circuit breakers. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1 -As shown, the utility model is a mobile detection device for vacuum circuit breaker, comprising a bracket 1, a workbench 15 and a base 3. The inner side of the workbench 15 is provided with three sleeves 2 at equal distances. A spring 21 is fixed in the sleeve 2. The other end of the spring 21 is connected to a limit plate 22. A connecting rod 23 is provided on the side of the limit plate 22. When the circuit breaker body needs to be subjected to a withstand voltage test, the circuit breaker is placed on the workbench 15. The circuit breaker squeezes the connecting rods 23 at the three locations. The connecting rods 23 are subjected to the circuit breaker. After being squeezed, it starts to move inward in the sleeve 2. The movement of the connecting rod 23 can make the limit plate 22 squeeze the spring 21. The spring 21 is compressed inside the sleeve 2 to generate a rebound force, which can make the end of the connecting rod 23 squeeze and fix the side of the circuit breaker body. The three connecting rods 23 arranged at equal distances can fix the circuit breaker in all directions. On the one hand, the circuit breaker can be quickly fixed and placed. On the other hand, it can avoid shaking of the body during pressure detection of the circuit breaker, which affects the detection effect.

[0020] The side wall of the base 3 is rotatably provided with a first rotating rod 32, and a first active bevel gear 33 is fixedly sleeved on the outer side of the first rotating rod 32. The first active bevel gear 33 is meshedly connected to the first driven bevel gear 34 on the side, and the first driven bevel gear 34 is fixedly sleeved with a second rotating rod 35. When the first rotating rod 32 starts to rotate, the first active bevel gear 33 fixedly sleeved on the outer side of the first rotating rod 32 starts to rotate, and the rotation of the first active bevel gear 33 can drive the meshed first driven bevel gear 34 to rotate. The first driven bevel gear 34 is fixedly sleeved on the second rotating rod 35, and can drive the second rotating rod 35 to rotate in the base 3.

[0021] Second active bevel gears 36 are fixedly provided at both side ends of the second rotating rod 35. The second active bevel gears 36 are meshedly connected to the second driven bevel gears 37. The second driven bevel gears 37 are fixedly installed at the ends of the screw rod 38. Similarly, the rotation of the second rotating rod 35 can drive the screw rod 38 to rotate.

[0022] The screw 38 is threadedly connected to the inside of the moving column 41, and the moving column 41 is slidably connected to the column 4. The lower end of the moving column 41 is fixedly connected to the installation frame 42. A roller 43 is rotatably provided in the installation frame 42. The rotation of the screw 38 can drive the threaded moving column 41 to move downward in the column 4. The movement of the moving column 41 can drive the installation frame 42 to move downward synchronously. The roller 43 provided in the installation frame 42 can support the upper device. The rotatably provided roller 43 can facilitate the movement of the upper detection device and the pressure detection device, thereby bringing convenience to the workers.

[0023] In the above scheme, an electric push rod 11 is provided above the bracket 1, and a pressure plate 12 is provided at the output end of the electric push rod 11. The pressure plate 12 is located directly above the workbench 15. By turning on the switch of the electric push rod 11, the pressure plate 12 at the output end of the electric push rod 11 can move downward, and the pressure plate 12 can press the circuit breaker body placed in the workbench 15.

[0024] In the above scheme, a pressure detector 13 is provided under the workbench 15, and a control panel 14 is provided on the side of the base 3. When the pressure plate 12 presses the circuit breaker body, the pressure detector 13 provided at the lower end of the workbench 15 can detect the pressure. Through the display screen on the control panel 14, the pressure value can be observed to detect whether the circuit breaker is qualified.

[0025] In the above solution, the limit plate 22 is slidably connected to the sleeve 2 , and the diameter of the limit plate 22 is larger than that of the sleeve 2 . The limit plate 22 can prevent the connecting rod 23 from being separated from the sleeve 2 .

[0026] In the above solution, a rubber pad 24 is provided at the end of the connecting rod 23. The rubber pad 24 can prevent the connecting rod 23 from causing damage to the contact end of the circuit breaker when it contacts the circuit breaker.

[0027] In the above solution, a handle 31 is fixedly provided on the outer side of the first rotating rod 32 , and the first rotating rod 32 is rotatably connected to the base 3 via a bearing. The handle 31 can facilitate the rotation of the first rotating rod 32 .

[0028] In the above solution, a fixing plate 44 is provided inside the column 4, and the screw rod 38 is rotatably connected to the fixing plate 44 via a bearing. The setting of the fixing plate 44 can ensure the stability of the rotation of the screw rod 38.

[0029] Working principle:

[0030] This kind of vacuum circuit breaker is easy to move the detection device. When working, the circuit breaker body to be detected is placed on the workbench 15, and the rubber pads 24 at three locations are squeezed. The rubber pads 24 can push the connecting rod 23 to move in the sleeve 2, and the spring 21 is squeezed. The spring 21 generates a rebound force, and the rubber pads 24 at three locations can clamp and fix the circuit breaker to ensure that the circuit breaker will not shake during pressure detection, which will affect the detection effect. When it is necessary to move the detection device, the handle 31 is turned, and the handle 31 is moved. 1 can drive the first rotating rod 32 to rotate, the rotation of the first rotating rod 32 causes the second rotating rod 35 to rotate through the first active bevel gear 33 and the first driven bevel gear 34, the rotation of the second rotating rod 35 causes the screw 38 to rotate through the second active bevel gear 36 and the second driven bevel gear 37, the rotation of the screw 38 can cause the moving column 41 to start moving downward, the roller 43 in the installation frame 42 moves downward, so that the roller 43 supports the upper device, which is convenient for pushing the device to move, bringing convenience to the workers.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
