Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, specifically a high-voltage outdoor disconnecting switch. Background Technology

[0002] A disconnector is a switching device mainly used for "isolating power supply, switching operations, and connecting and disconnecting small current circuits" without arc extinguishing function. When the disconnector is in the open position, there is an insulation distance between the contacts that meets the specified requirements and a clear disconnection mark. When the disconnector is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. Traditional outdoor disconnectors often require manual adjustment to open or close, which is risky to operate. Moreover, the insulators on the disconnector are mostly fixed, making disassembly inconvenient. In order to improve the above situation, a high-voltage outdoor disconnector is proposed.

[0003] An outdoor high-voltage disconnector disclosed in authorization announcement number CN219916997U includes a base, an insulator mounted on the top of the base, a connecting frame mounted on the top of the insulator, a connecting block connected to the end of the connecting frame away from the insulator, a threaded pipe connected to the end of the connecting block away from the connecting frame, a threaded sleeve sleeved on the outside of the threaded pipe, a pull sleeve movably sleeved on the end of the threaded sleeve away from the connecting block, and a preload member movably sleeved inside the pull sleeve. Although it allows the cable to be inserted into the threaded tube, rotating the threaded sleeve drives the pull sleeve to move to the left, which allows the clamping plate to gradually insert into the interior of the moving threaded tube, clamping the cable inward, thus pre-fixing the cable. Then, the end of the cable is fixed by the fastening bolts, which facilitates the connection of the cable. However, this does not solve the problem that existing disconnecting switches are not conducive to automatically disconnecting closed circuits during use, nor to quickly disassembling and replacing insulators, which affects the safety of use and the convenience of maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a high-voltage outdoor disconnect switch to solve the problems mentioned in the background art, such as the disconnect switch being inconvenient to automatically disconnect the closed circuit, making it difficult to quickly disassemble and replace insulators, thus affecting the safety of use and the convenience of maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage outdoor disconnect switch, comprising a placement box and a support frame. The placement box contains the support frame, and the support frame contains multiple sets of plug-in sockets symmetrically arranged inside. Each plug-in socket has a plug-in post slidably arranged inside. Each plug-in socket has a limit ring on its side wall, and each limit ring has a limit post slidably arranged inside. Each limit post has a spring on its surface, and both ends of the spring are connected to the limit post and the limit ring, respectively. Each plug-in post has a connecting block at its top, and each connecting block has an insulator installed at its top. One set of insulators has an input terminal at its top, and another set of insulators has an output terminal at its top. A connecting shaft is movably installed at the center of the support frame. Multiple sets of linkage arms are fixedly installed at equal intervals on the surface of the connecting shaft. Each linkage arm has an adjusting arm movably installed at its top. Each adjusting arm has a connecting rod at its end away from the linkage arm. Each connecting rod has a movable shaft on its side wall, and the adjusting arm is movably connected to the connecting rod through the movable shaft. The connecting rod is movably connected to the input terminal.

[0006] Preferably, an electric push rod is movably mounted on the side wall of the placement box, and a push arm is mounted on the output end of the electric push rod.

[0007] Preferably, an adjusting rod is provided at the end of the push arm away from the electric push rod, and a linkage shaft is provided at the end of the adjusting rod near the push arm.

[0008] Preferably, the push arm is movably connected to the adjusting rod via a linkage shaft, and the adjusting rod is fixedly connected to the connecting shaft.

[0009] Preferably, a storage battery is installed at the top of the storage box, and a support shaft is installed at the top of the storage box on the side of the storage battery.

[0010] Preferably, a placement frame is movably mounted on the top of the support shaft, and a servo motor is mounted on the side wall of the support shaft.

[0011] Preferably, a photovoltaic panel is installed on the side wall of the placement rack, and the photovoltaic panel is fixedly connected to the placement rack.

[0012] Preferably, an arc-shaped rack is installed at the bottom of the placement frame, and a gear is installed at the output end of the servo motor, with the gear meshing with the arc-shaped rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the disconnecting switch not only realizes automatic disconnection of closed circuits and facilitates quick disassembly and replacement of insulators, but also improves the safety of use and the convenience of maintenance; (1) Install the disconnect switch into the placement box and place the placement box in the usage position. The placement box protects the disconnect switch. Install the photovoltaic panel onto the placement box through the support shaft. When sunlight shines on the photovoltaic panel, it generates electricity and stores it in the battery. The battery provides power to the electrical components on the device. The servo motor drives the gear to rotate, and the gear drives the placement frame to rotate through the arc rack. The placement frame drives the photovoltaic panel to rotate, thereby adjusting the photovoltaic panel to face the sun. At the same time, a PLC component can be set to control the opening and closing of the servo motor, so that it rotates intermittently, thereby following the position of the sun to better generate and store electricity. When the circuit needs to be closed, the electric push rod drives the push arm to move, the push arm drives the adjusting rod to rotate via the linkage shaft, the adjusting rod drives the connecting shaft to rotate, the connecting shaft drives the linkage arm to rotate, the linkage arm drives the adjusting arm to rotate, and the adjusting arm drives the connecting rod to rotate via the movable shaft. The connecting rod is rotated to the output terminal, connecting the input terminal to the output terminal through the connecting rod, thus closing the circuit. When the circuit needs to be opened, the electric push rod is opened in reverse, which disconnects the connecting rod from the output terminal, thus opening the circuit. This completes the use of the isolating switch, realizing automatic opening and closing of the circuit, reducing manual operation, and improving the safety of use. (2) Pull the limiting post outward. The limiting post slides inside the limiting ring. The limiting post drives the spring to contract and deform, causing the limiting post to disengage from the groove on the surface of the plug post, separating the plug post from the plug seat. Then pull the insulator upward. The insulator drives the connecting block and the plug post to move upward, so as to quickly remove the insulator from the surface of the support frame. After replacement, repeat the above operation in reverse to install the new insulator onto the support frame. This realizes quick disassembly and replacement of insulators and improves the convenience of maintenance. Attached Figure Description

[0017] Please see Figure 1-5 This utility model provides an embodiment of a high-voltage outdoor disconnect switch, comprising a placement box 1 and a support frame 4. The placement box 1 contains the support frame 4, and the support frame 4 contains multiple sets of plug-in sockets 23 symmetrically arranged inside. Each plug-in socket 23 has a slidably mounted plug post 26 inside. Each plug-in socket 23 has a limit ring 27 on its side wall, and each limit ring 27 has a slidably mounted limit post 24 inside. Each limit post 24 has a spring 25 on its surface, and both ends of the spring 25 are connected to the limit post 24 and the limit ring 27, respectively. Each plug post 26 has a connecting block 22 at its top, and each connecting block 22 has a connecting block 22 mounted on its top. The frame is equipped with insulators 15, with an input terminal 14 at the top of one set of insulators 15 and an output terminal 16 at the top of another set of insulators 15. A connecting shaft 9 is movably installed at the center of the support frame 4. Multiple sets of linkage arms 10 with equal spacing are fixedly installed on the surface of the connecting shaft 9. An adjusting arm 11 is movably installed at the top of each linkage arm 10. A connecting rod 13 is provided at the end of each adjusting arm 11 away from the linkage arm 10. A movable shaft 12 is provided on the side wall of each connecting rod 13. The adjusting arm 11 is movably connected to the connecting rod 13 through the movable shaft 12. The connecting rod 13 is movably connected to the input terminal 14. The disconnect switch is installed in the placement box 1, and the placement box 1 is installed in the usage position. The placement box 1 protects the disconnect switch. The photovoltaic panel 3 is installed on the placement box 1 via the support shaft 18. Sunlight shines on the photovoltaic panel 3, generating electricity which is stored in the battery 2. The battery 2 provides power to the electrical components of the device. The servo motor 19 is turned on, driving the gear 20 to rotate. With the meshing of the gear 20 and the arc rack 21, and the movable cooperation between the placement frame 17 and the support shaft 18, the gear 20 drives the placement frame 17 to rotate via the arc rack 21. The placement frame 17 then drives the photovoltaic panel 3 to rotate, adjusting the photovoltaic panel 3 to face the sun. A PLC component can also be set to control the opening and closing of the servo motor 19, making it rotate intermittently to follow the sun's direction. The circuit is positioned at the positive position for better power generation and storage. When the circuit needs to be closed, the electric push rod 5 is opened, which drives the push arm 6 to move. The push arm 6 drives the adjusting rod 8 to rotate via the linkage shaft 7. The adjusting rod 8 drives the connecting shaft 9 to rotate. The connecting shaft 9 drives the linkage arm 10 to rotate. The linkage arm 10 drives the adjusting arm 11 to rotate. The adjusting arm 11 drives the connecting rod 13 to rotate via the movable shaft 12. The connecting rod 13 is rotated to the output terminal 16, and the input terminal 14 is connected to the output terminal 16 via the connecting rod 13 to close the circuit. When the circuit needs to be disconnected, the electric push rod 5 is opened in the opposite direction to disconnect the connecting rod 13 from the output terminal 16, thus disconnecting the circuit. This completes the use of the isolating switch, realizing automatic circuit disconnection and closure, reducing manual operation, and improving the safety of use. An electric push rod 5 is movably installed on the side wall of the placement box 1. The electric push rod 5 serves as a power drive. A push arm 6 is installed at the output end of the electric push rod 5. An adjustment rod 8 is provided at the end of the push arm 6 away from the electric push rod 5. A linkage shaft 7 is provided at the end of the adjustment rod 8 close to the push arm 6. The push arm 6 is movably connected to the adjusting rod 8 via the linkage shaft 7, and the adjusting rod 8 is fixedly connected to the connecting shaft 9. The top of the placement box 1 is equipped with a storage battery 2, and the top of the placement box 1 on the side of the storage battery 2 is equipped with a support shaft 18. A placement frame 17 is movably mounted on the top of the support shaft 18. A servo motor 19 is mounted on the side wall of the support shaft 18. The servo motor 19 serves as a power drive. A photovoltaic panel 3 is mounted on the side wall of the placement frame 17, and the photovoltaic panel 3 is fixedly connected to the placement frame 17. An arc-shaped rack 21 is installed at the bottom of the placement rack 17, and a gear 20 is installed at the output end of the servo motor 19, and the gear 20 meshes with the arc-shaped rack 21. When it is necessary to disassemble and replace insulator 15, pull out the limiting post 24. The limiting post 24 slides inside the limiting ring 27. Under the limiting cooperation of the limiting ring 27, the limiting post 24 drives the spring 25 to contract and deform, so that the limiting post 24 disengages from the groove on the surface of the plug post 26, separating the plug post 26 from the plug seat 23. Then pull the insulator 15 upward. The insulator 15 drives the connecting block 22 and the plug post 26 to move upward, so as to quickly remove the insulator 15 from the surface of the support frame 4. After the replacement is completed, repeat the above operation in reverse to install the new insulator 15 onto the support frame 4. This realizes quick disassembly and replacement of insulators and improves the convenience of maintenance.

[0018] Working Principle: The disconnect switch is installed in the placement box 1, which is then positioned at the desired location. The placement box 1 protects the disconnect switch. The photovoltaic panel 3 is mounted onto the placement box 1 via the support shaft 18. A servo motor 19 drives a gear 20 to rotate, which in turn drives a placement frame 17 via an arc-shaped rack 21. The placement frame 17 then rotates the photovoltaic panel 3, adjusting it to face the sun. A PLC can also be used to control the opening and closing of the servo motor 19, allowing it to rotate intermittently to follow the sun's position and better generate and store electricity. When the circuit needs to be closed, the electric push rod 5 moves the push arm 6, which in turn drives an adjusting rod 8 via a linkage shaft 7. The adjusting rod 8 then drives a connecting shaft 9, which in turn drives a linkage arm 10. The linkage arm 10 then drives an adjusting arm 11, which in turn drives a connecting rod 13 via a movable shaft 12, rotating the connecting rod 13 to the desired position. On the output terminal 16, the input terminal 14 is connected to the output terminal 16 via the connecting rod 13 to close the circuit. When the circuit needs to be disconnected, the electric push rod 5 is opened in reverse to disengage the connecting rod 13 from the output terminal 16, thus disconnecting the circuit and completing the operation of the disconnecting switch. If the insulator 15 needs to be disassembled and replaced, the limiting post 24 is pulled outward. The limiting post 24 slides inside the limiting ring 27. Under the limiting cooperation of the limiting ring 27, the limiting post 24 drives the spring 25 to contract and deform, causing the limiting post 24 to disengage from the groove on the surface of the plug post 26, separating the plug post 26 from the plug seat 23. Then, the insulator 15 is pulled upward, and the insulator 15 drives the connecting block 22 and the plug post 26 to move upward, so that the insulator 15 can be quickly removed from the surface of the support frame 4. After replacement, the above operation is repeated in reverse to install the new insulator 15 onto the support frame 4. The above is the complete operation of the high-voltage outdoor disconnecting switch.
