Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: an isolator automatic debugging device, including a base plate 4, a plurality of pulleys 6 are arranged below the base plate 4, the base plate 4 and the plurality of pulleys 6 are connected by a plurality of connecting blocks 5, a debugging component 1 is arranged above the base plate 4, an electrical cabinet 3 is installed on the side of the debugging component 1 close to the base plate 4, a power switch 7 is installed on one side of the electrical cabinet 3, the base plate 4 and the debugging component 1 are connected by a lifting buffer device 2, and an isolation protection device 8 is installed on the outside of the debugging component 1.

[0023] Specifically, the lifting and buffering device 2 includes a fixed shell 21, a lifting plate 22, a first screw 23, a threaded hole 24 and a buffering assembly 25. The fixed shell 21 is provided on the side of the electrical cabinet 3 away from the power switch 7, and the lifting plate 22 is installed below the debugging assembly 1 and at a position located on the inner side of the fixed shell 21. A plurality of threaded holes 24 are provided on the side of the lifting plate 22 away from the electrical cabinet 3. The first screw 23 is threadedly installed on the top of the fixed shell 21, and the fixed shell 21 and the base plate 4 are connected via the buffering assembly 25.

[0024] By adopting the above technical solution, the equipment can adjust the height of the debugging component 1 to a certain extent through the cooperation of the lifting plate 22 and the first screw 23 and other structures when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the buffer assembly 25 includes a damper 251, an elastic rubber frame 252 and a support frame 254. The support frame 254 is installed below the fixed shell 21 and at a position outside the base plate 4. The elastic rubber frame 252 is installed between the inner top surface of the support frame 254 and the outer top surface of the base plate 4. A plurality of dampers 251 are installed between the inner top surface of the support frame 254 and the outer top surface of the base plate 4 and at a position inside the elastic rubber frame 252.

[0026] By adopting the above technical solution, the equipment can buffer external vibration to a certain extent through the cooperation of the damper 251 and the elastic rubber frame 252, thereby reducing the possibility of adverse effects on the debugging work and ensuring the normal progress of the work.

[0027] Specifically, the buffer assembly 25 further includes a second screw 253 , and two second screws 253 are threadedly mounted on the bottom of the support frame 254 .

[0028] By adopting the above technical solution, the staff can fix the relative position between the support frame 254 and the base plate 4 by two second screws 253 when necessary, thereby preventing the buffering work from being carried out and better meeting the work needs in different situations.

[0029] When this embodiment is used, when it is necessary to use the equipment to automatically debug the isolator, push the equipment and move it to the working position through the pulleys 6 under each connecting block 5, then turn the first screw 23 on the fixed shell 21 in the lifting buffer device 2 to disengage it from the threaded hole 24, then pull the debugging component 1 to move it and the lifting plate 22 to the required height, then reversely rotate the first screw 23 to connect it with the corresponding threaded hole 24, then turn the two second screws 253 in the buffer component 25 to disengage it from the base plate 4, thereby causing the support frame 254 to lose relative fixation with the base plate 4, and then the equipment can buffer external vibrations through the cooperation of the damper 251 and the elastic rubber frame 252, and then the staff operates the power switch 7 on the electrical cabinet 3, and then connects the isolator to the transformer and other structures on the debugging component 1 through wires, so as to perform automatic debugging.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that: the isolation protection device 8 includes a fixing frame 81, a connecting plate 82, a transparent shell 83, a screw rod 84 and a knob 85, the fixing frame 81 is installed on one side of the debugging component 1, the screw rod 84 is installed at the central position of the fixing frame 81 through a bearing, the knob 85 is installed below the screw rod 84, the connecting plate 82 is installed at the outer side of the screw rod 84 and at the inner side of the fixing frame 81 through a thread, and the transparent shell 83 is installed on the connecting plate 82 and at a position above the debugging component 1.

[0032] By adopting the above technical solution, the device can isolate and protect the structure on the debugging component 1 through the cooperation of structures such as the transparent shell 83 and the screw rod 84 when necessary, thereby reducing the possibility of accidental damage to the structure on the debugging component 1.

[0033] Specifically, the fixing frame 81 is designed to be L-shaped, and the inner side of the fixing frame 81 and one side of the connecting plate 82 are in close contact with each other.

[0034] By adopting the above technical solution, the equipment can limit and guide the movement of the connecting plate 82 to a certain extent through the fixing frame 81, thereby preventing the connecting plate 82 from rotating and deviating during the movement, thereby ensuring the normal operation.

[0035] When this embodiment is used, when it is necessary to isolate and protect the transformer and other structures on the debugging component 1, the staff rotates the knob 85 in the isolation protection device 8, thereby driving the screw rod 84 to rotate. The screw rod 84 is threadedly connected to the connecting plate 82, and the connecting plate 82 and the fixing frame 81 are tightly attached to each other, so the screw rod 84 drives the connecting plate 82 and the transparent shell 83 thereon to descend until the transparent shell 83 covers the transformer and other structures on the debugging component 1, thereby isolating and protecting the transformer and other structures on the debugging component 1.

[0036] The structure and principle of the debugging component 1, electrical cabinet 3, base plate 4, connecting block 5, pulley 6, and power switch 7 composed of a mounting plate, a multimeter, a resistance box, a temperature control box, a transformer, a signal generator and a second signal isolator in the utility model have been disclosed in an isolator automatic debugging machine disclosed in Chinese patent application No. 202022609044.8. Its working principle is to connect the required instruments through wires. For example, if the withstand voltage performance of the isolator is measured, the transformer is connected to the second signal isolator, and then the multimeter is connected. After turning on the power switch, the withstand voltage performance of the isolator is measured by adjusting the voltage of the transformer. If the influence of temperature on the output of the isolator is measured, the signal generator is connected to the temperature control box, the temperature control box is connected to the multimeter, and the temperature is adjusted through the control panel after turning on the power switch, and then the detection is carried out. If the change of the isolator according to different resistance values ​​is measured, the signal generator is connected to the second signal isolator, the second signal isolator is connected to the resistance box, the resistance box is connected to the multimeter, and the power switch is turned on to measure by adjusting the resistance value of the resistance box.

[0037] The structure and principle of the damper 251 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese patent application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when the equipment needs to be used to automatically debug the isolator, the equipment is pushed and moved to the working position through the pulleys 6 under each connecting block 5, and then the first screw 23 on the fixed shell 21 in the lifting buffer device 2 is screwed to disengage it from the threaded hole 24, and then the debugging component 1 is pulled to move it and the lifting plate 22 to the required height, and then the first screw 23 is rotated in the opposite direction to connect it with the corresponding threaded hole 24, and then the two second screws 253 in the buffer component 25 are screwed to disengage it from the bottom plate 4, thereby causing the support frame 254 to lose relative fixation with the bottom plate 4, and then the equipment can be adjusted by the damper 251 and the elastic rubber frame 252. In order to buffer the external vibration, the staff then operates the power switch 7 on the electrical cabinet 3, and then connects the isolator to the transformer and other structures on the debugging component 1 through a wire, so as to perform automatic debugging; when it is necessary to isolate and protect the transformer and other structures on the debugging component 1, the staff turns the knob 85 in the isolation protection device 8, thereby driving the screw rod 84 to rotate. The screw rod 84 is threadedly connected to the connecting plate 82, and the connecting plate 82 and the fixing frame 81 are tightly attached to each other, so the screw rod 84 drives the connecting plate 82 and the transparent shell 83 thereon to descend until the transparent shell 83 covers the transformer and other structures on the debugging component 1, thereby isolating and protecting the transformer and other structures on the debugging component 1.
