Description

Technical Field

[0001] This invention relates to the field of electrical components, and in particular to high electrical insulation solid-sealed poles. Background Technology

[0002] Solid-sealed poles are formed by embedding the vacuum interrupter and related conductive parts of the circuit breaker into a solid insulating material such as epoxy resin or thermoplastic material that is easy to cure, making the entire circuit breaker pole a single component.

[0003] When the equipment is in use, during the power-off process, the hydraulic cylinder and the terminal block are usually used to make contact. The extension rod of the hydraulic cylinder controls the raising and lowering of the terminal block to make contact between the two terminals. The whole process requires the use of power to control the start of the hydraulic cylinder. During the closing process, the disconnect switch needs to be closed first, and then the circuit breaker in the solid-sealed pole needs to be closed. The solid-sealed pole is energized throughout the whole process, and the operation is quite dangerous. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a high electrical insulation solid-sealed pole.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A high electrical insulation solid-sealed pole includes an upper insulating shell and a lower insulating shell. The upper insulating shell is fixedly installed on the upper surface of the lower insulating shell. A docking mechanism is provided on the upper insulating shell. An adjustment mechanism is provided inside the upper insulating shell. An insulation mechanism is provided inside the upper insulating shell.

[0007] The adjustment mechanism includes a circular suspended fixing plate, which is fixedly installed on the inner wall of the lower insulating shell. A circular tube is provided on the upper surface of the circular suspended fixing plate, and a circular connecting plate is fixedly installed on the lower surface of the circular tube. A circular rotating tube is fixedly installed below the circular connecting plate and passes through the circular suspended fixing plate. A circular gear plate is fixedly installed on the end of the circular rotating tube and fits against the lower surface of the circular suspended fixing plate. A vertical plate and a horizontal plate are fixedly installed on the upper surface of the circular suspended fixing plate. An outer rectangular tube sleeve is fixedly installed between the horizontal plates. A rectangular telescopic rod is movably engaged inside the outer rectangular tube sleeve. A side lifting indicator plate is fixedly installed on the side wall of the rectangular telescopic rod, and a circular lifting column is fixedly installed on the lower surface of the side lifting indicator plate. The upper surface of the circular tube and the end of the circular lifting column are in contact with each other.

[0008] As a preferred embodiment of the present invention, the vertical plate and the horizontal plate are combined to form an L-shaped support structure, and the horizontal plate is disposed on both sides of the outer rectangular tube sleeve.

[0009] As a preferred embodiment of the present invention, a rectangular mounting base is provided on the lower surface of the lower insulating housing for sealing, and the lower surface of the circular toothed disc is in contact with the rectangular mounting base.

[0010] As a preferred embodiment of the present invention, the lower surface of the lower insulating shell is provided with a bottom circular groove, and the side wall of the lower insulating shell is provided with a rectangular side notch that communicates with the bottom circular groove.

[0011] As a preferred embodiment of the present invention, an arc-shaped groove is provided on the upper surface of the circular tube, and the circular lifting column is engaged in the calling groove provided on the upper surface of the circular tube.

[0012] As a preferred embodiment of the present invention, a circular rod is fixedly installed on the upper surface of the circular suspended fixing plate, and a spring is provided on the lower surface of the side lifting indicator plate. The two ends of the spring are fixedly installed together with the side lifting indicator plate and the circular rod, respectively.

[0013] As a preferred embodiment of the present invention, the insulating mechanism includes a first embedded mounting tube and a second embedded mounting tube, which are respectively fixedly installed at both ends of the upper insulating shell. A terminal is provided inside the first embedded mounting tube, and a contact is provided at the end of the terminal. A corrugated tube is provided outside the terminal, and a limiting sleeve is provided outside the corrugated tube. A vacuum interrupter is provided on the limiting sleeve, and the vacuum interrupter is sleeved and installed outside the two contacts. Both the limiting sleeve and the vacuum interrupter are fixedly installed inside the upper insulating shell.

[0014] As a preferred embodiment of the present invention, the docking mechanism includes a circular connecting tube, which is fixedly installed on the side walls of the first embedded mounting tube and the second embedded mounting tube. The circular connecting tube is engaged with the upper insulating shell and the lower insulating shell. An outer rotating tube is provided inside the circular connecting tube, and an annular limiting tube is fixedly installed outside the outer rotating tube. The annular limiting tube is movably engaged inside the circular connecting tube. A circular pushing pin is movably engaged inside the outer rotating tube, and a rectangular preset groove distributed in a circular pattern is opened on the end of the circular pushing pin.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. This device controls the power supply to the equipment by rotating the circular tube, causing the circular lifting column on the tube to slide on the upper surface of the tube. The up and down movement of the circular lifting column changes the contact between the contacts. The control process does not require current, which improves the safety of the equipment when the power is off.

[0017] 2. When the side lifting indicator plate moves upward, it will cause the spring to deform. When the spring deforms, it will generate a reverse pulling force, which will exert a downward pulling force on the side lifting indicator plate. When the circular lifting column reaches the groove position on the upper surface of the circular tube, it will fit better with the upper surface of the circular tube, making the lifting accuracy of the terminal block higher and improving the control accuracy of the equipment.

[0018] 3. The present invention adopts an eccentrically designed circular toothed disc, and the center point of the circular toothed disc is designed to be on the same horizontal line as the center of the upper insulating shell, rather than the center point of the lower insulating shell. This design allows the edge of the circular toothed disc to be exposed in the rectangular side notch, making it easier to rotate the circular toothed disc and control the equipment, making operation more convenient.

[0019] 4. This device compresses the ends of the circular push pins, causing them to retract and secure the cable, thus ensuring the cable's stability within the equipment and enhancing its cable-fixing effect.

[0020] 5. When it is necessary to adjust the angle of the cable, rotate the outer rotating tube to allow it to rotate inside the circular connecting tube, thereby rotating the cable inside the circular push-in pin and adjusting the angle of the cable, making cable installation more convenient.

[0030] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0031] like Figures 1 to 8 As shown, the high electrical insulation solid-sealed pole includes an upper insulating shell 1 and a lower insulating shell 2. The upper insulating shell 1 is fixedly installed on the upper surface of the lower insulating shell 2. A docking mechanism is provided on the upper insulating shell 1. An adjustment mechanism is provided inside the upper insulating shell 1. An insulation mechanism is provided inside the upper insulating shell 1.

[0032] Specifically, the aforementioned adjustment mechanism includes a circular suspended fixing plate 34, which is fixedly installed on the inner wall of the lower insulating housing 2. A circular tube 44 is provided on the upper surface of the circular suspended fixing plate 34, and a circular connecting plate 51 is fixedly installed on the lower surface of the circular tube 44. A circular rotating tube 52 is fixedly installed below the circular connecting plate 51, and the circular rotating tube 52 passes through the circular suspended fixing plate 34. A circular geared disc 33 is fixedly installed at the end of the circular rotating tube 52. The circular suspended fixing plate 34 is fitted to the lower surface of the circular suspended fixing plate 34. A vertical plate 35 and a horizontal plate 36 are fixedly installed on the upper surface of the circular suspended fixing plate 34. An outer rectangular tube sleeve 45 is fixedly installed between the horizontal plates 36. A rectangular telescopic rod 37 is movably engaged inside the outer rectangular tube sleeve 45. A side lifting indicator plate 39 is fixedly installed on the side wall of the rectangular telescopic rod 37. A circular lifting column 43 is fixedly installed on the lower surface of the side lifting indicator plate 39. The upper surface of the circular tube 44 and the end of the circular lifting column 43 are fitted together.

[0033] The vertical plate 35 and the horizontal plate 36 are combined to form an L-shaped support structure, with the horizontal plate 36 set on both sides of the outer rectangular tube sleeve 45.

[0034] A rectangular mounting base 3 is provided on the lower surface of the lower insulating housing 2 for sealing, and the lower surface of the circular toothed disc 33 is in contact with the rectangular mounting base 3.

[0035] The lower surface of the lower insulating housing 2 is provided with a bottom circular groove 32, and the side wall of the lower insulating housing 2 is provided with a rectangular side notch 31 that communicates with the bottom circular groove 32.

[0036] An arc-shaped groove is provided on the upper surface of the circular tube 44, and the circular lifting column 43 is engaged in the calling groove provided on the upper surface of the circular tube 44.

[0037] A circular rod 42 is fixedly installed on the upper surface of the circular suspended fixing plate 34, and a spring 41 is provided on the lower surface of the side lifting indicator plate 39. The two ends of the spring 41 are fixedly installed together with the side lifting indicator plate 39 and the circular rod 42, respectively.

[0038] When using the equipment, it is necessary to start the equipment by rotating the circular gear disk 33. The circular gear disk 33 is eccentrically designed, with the center point of the circular gear disk 33 on the same horizontal line as the center of the upper insulating shell 1, rather than the center point of the lower insulating shell 2. This design allows the edge of the circular gear disk 33 to be exposed in the rectangular side notch 31, making it easier to rotate the circular gear disk 33 and control the equipment, making operation more convenient.

[0039] As the circular gear disc 33 rotates, it causes the circular rotating tube 52 and the circular connecting plate 51 to rotate as well. When the circular rotating tube 52 rotates within the circular suspended fixing plate 34, the circular connecting plate 51 drives the circular tube body 44 to rotate on the circular suspended fixing plate 34. As the circular tube body 44 rotates, the circular lifting column 43 slides on its upper surface. Following the groove on the upper surface of the circular tube body 44, the circular lifting column 43 moves up and down. A rectangular plane is provided on the upper surface of the circular tube body 44, allowing the circular rod 42 to stop on it. When the circular lifting column 43 moves upward, it pushes the side lifting indicator plate 39 upward. As the side lifting indicator plate 39 moves upward, it drives the rectangular... The telescopic rod 37 moves upward. When the rectangular telescopic rod 37 moves upward, it slides inside the outer rectangular sleeve 45. When the rectangular telescopic rod 37 moves upward, it drives the terminal 23 to move upward. The upward movement of the terminal 23 drives the contact 24 to move upward. By bringing one contact 24 closer to the other, the current between them is made to conduct. A vacuum interrupter 27 is provided outside the contact 24 for limiting. This device controls the rotation of the circular tube 44, causing the circular lifting column 43 on the circular tube 44 to slide on the upper surface of the circular tube 44. By moving the circular lifting column 43 up and down, the contact between the contacts 24 is changed, realizing the control of the power supply to the equipment. The control process does not require current, which improves the safety of the equipment power failure control.

[0040] When the side lifting indicator plate 39 moves upward, it will cause the spring 41 to deform. When the spring 41 deforms, it will generate a reverse pulling force, which will exert a downward pulling force on the side lifting indicator plate 39. When the circular lifting column 43 reaches the groove position on the upper surface of the circular tube 44, it will fit better with the upper surface of the circular tube 44, making the lifting accuracy of the terminal 23 higher and improving the control accuracy of the equipment.

[0041] In some specific embodiments, the above-mentioned insulation mechanism includes a first embedded mounting tube 21 and a second embedded mounting tube 22. The first embedded mounting tube 21 and the second embedded mounting tube 22 are respectively fixedly installed at both ends of the upper insulating shell 1. A terminal 23 is provided inside the first embedded mounting tube 21. A contact 24 is provided at the end of the terminal 23. A corrugated tube 25 is provided outside the terminal 23. A limiting sleeve 26 is provided outside the corrugated tube 25. A vacuum interrupter 27 is provided on the limiting sleeve 26. The vacuum interrupter 27 is sleeved and installed outside the two contacts 24. Both the limiting sleeve 26 and the vacuum interrupter 27 are fixedly installed inside the upper insulating shell 1.

[0042] The docking mechanism includes a circular connecting tube 11, which is fixedly installed on the side wall of the first embedded mounting tube 21 and the second embedded mounting tube 22. The circular connecting tube 11 is engaged with the upper insulating shell 1 and the lower insulating shell 2. An outer rotating tube 14 is provided inside the circular connecting tube 11. An annular limiting tube 15 is fixedly installed outside the outer rotating tube 14. The annular limiting tube 15 is movably engaged inside the circular connecting tube 11. A circular pushing pin 12 is movably engaged inside the outer rotating tube 14. A rectangular preset groove 13 distributed in a circle is opened on the end of the circular pushing pin 12.

[0043] When using the equipment, the end of the cable needs to be installed on the circular push pin 12. An installation hole is provided on the side wall of the circular push pin 12. The end of the cable is then secured inside the circular push pin 12. After securing, the circular push pin 12 is pushed, allowing it to move within the outer rotating tube 14. The radius of the outer rotating tube 14 gradually decreases from the outside to the inside. Thus, when the circular push pin 12 moves within the outer rotating tube 14, the end of the circular push pin 12 located inside the outer rotating tube 14 will be subjected to pressure from the inner wall of the outer rotating tube 14. The compression causes the end of the circular push pin 12 to retract along the trajectory of the rectangular preset groove 13, clamping the cable. After fixing, the end of the circular push pin 12 contacts the conductive plate inside the first embedded mounting tube 21, connecting the cable to the terminal 23. This device fixes the cable by compressing the end of the circular push pin 12, ensuring the stability of the cable in the equipment and making the equipment more effective at fixing the cable.

[0044] When the angle of the cable needs to be adjusted, the outer rotating tube 14 is rotated inside the circular connecting tube 11, thereby rotating the cable inside the circular push-in pin 12, allowing the cable angle to be adjusted and making cable installation more convenient.

[0045] Working principle:

[0046] Step 1: When using the equipment, the end of the cable needs to be installed on the circular push pin 12. An installation hole is provided on the side wall of the circular push pin 12. The end of the cable is then secured inside the circular push pin 12. After securing, push the circular push pin 12 to move it within the outer rotating tube 14. The radius of the outer rotating tube 14 gradually decreases from the outside to the inside. Thus, when the circular push pin 12 moves within the outer rotating tube 14, the end of the circular push pin 12 located inside the outer rotating tube 14 will be subjected to the force of the outer rotating tube 14. The compression of the inner wall causes the end of the circular push pin 12 to retract along the trajectory of the rectangular preset groove 13, clamping the cable. After fixing, the end of the circular push pin 12 contacts the conductive plate inside the first embedded mounting tube 21, connecting the cable to the terminal 23. This device fixes the cable by compressing the end of the circular push pin 12, ensuring the stability of the cable in the equipment and making the equipment more effective at fixing the cable.

[0047] Step 2: When it is necessary to adjust the angle of the cable, rotate the outer rotating tube 14 so that the outer rotating tube 14 rotates inside the circular connecting tube 11, thereby rotating the cable inside the circular push-in pin 12, so that the angle of the cable can be adjusted, making it easier to install the cable.

[0048] Step 3: When using the equipment, it is necessary to start the equipment by rotating the circular gear 33 to open and close the equipment. The circular gear 33 is eccentrically designed, with the center point of the circular gear 33 on the same horizontal line as the center of the upper insulating shell 1, rather than the center point of the lower insulating shell 2. This design allows the edge of the circular gear 33 to be exposed in the rectangular side notch 31, making it easier to rotate the circular gear 33 and control the equipment, making operation more convenient.

[0049] Step 4: As the circular gear disc 33 rotates, it causes the circular rotating tube 52 and the circular connecting plate 51 to rotate as well. When the circular rotating tube 52 rotates within the circular suspended fixing plate 34, the circular connecting plate 51 drives the circular tube body 44 to rotate on the circular suspended fixing plate 34. As the circular tube body 44 rotates, the circular lifting column 43 slides on its upper surface. Following the groove on the upper surface of the circular tube body 44, the circular lifting column 43 moves up and down. A rectangular plane is provided on the upper surface of the circular tube body 44, allowing the circular rod 42 to stop on it. When the circular lifting column 43 moves upward, it pushes the side lifting indicator plate 39 upward. As the side lifting indicator plate 39 moves upward, it drives... The rectangular telescopic rod 37 moves upward. When the rectangular telescopic rod 37 moves upward, it slides inside the outer rectangular sleeve 45. When the rectangular telescopic rod 37 moves upward, it drives the terminal 23 to move upward. The upward movement of the terminal 23 drives the contact 24 to move upward. By bringing one contact 24 closer to the other, the current between them is made to conduct. A vacuum interrupter 27 is provided outside the contact 24 for limiting. This device controls the rotation of the circular tube 44, causing the circular lifting column 43 on the circular tube 44 to slide on the upper surface of the circular tube 44. By moving the circular lifting column 43 up and down, the contact between the contacts 24 is changed, realizing the control of the power supply to the equipment. The control process does not require current, which improves the safety of the equipment when the power is off.

[0050] Step 5: When the side lifting indicator plate 39 moves upward, it will cause the spring 41 to deform. When the spring 41 deforms, it will generate a reverse pulling force, which will exert a downward pulling force on the side lifting indicator plate 39. When the circular lifting column 43 reaches the groove position on the upper surface of the circular tube 44, it will fit better with the upper surface of the circular tube 44, making the lifting accuracy of the terminal block 23 higher and improving the control accuracy of the equipment.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
