Description

Technical Field

[0001] This invention relates to the field of disconnecting switch technology, specifically a push-pull type outdoor high-voltage disconnecting switch. Background Technology

[0002] In power systems, outdoor high-voltage disconnect switches are key power distribution equipment, mainly used for the isolation, conversion and switching operations of high-voltage circuits. Their operational stability and reliability directly affect the safe power supply of the power system.

[0003] However, existing outdoor high-voltage disconnect switches still have many technical defects in practical applications: In terms of conductive connection and operational performance, traditional outdoor high-voltage disconnect switches mostly adopt rotary or plug-in conductive structures, and the opening and closing operations rely on manual drive or simple mechanical transmission. Manual operation is not only labor-intensive, but also prone to uneven operation force leading to misalignment of conductive components, resulting in poor contact, which in turn increases contact resistance, causes power loss, and may even cause components to overheat and burn out; the simple mechanical transmission structure lacks precise guidance and buffer design, and the conductive components are prone to hard collisions when they are connected, which aggravates component wear, shortens the service life of the equipment, and at the same time, the frictional resistance during transmission is large, which is prone to jamming failure, affecting the smoothness and timeliness of opening and closing operations; Regarding outdoor protection performance, the existing disconnect switch base plate mounting structure is not sufficiently protected. When the base plate is fixed by bolts with the mounting groove, the mounting groove and bolts are directly exposed to the outdoor environment. Rainwater, dust, corrosive impurities, etc. can easily enter the mounting groove, causing bolt corrosion and jamming. Later maintenance requires a lot of time to clean or replace rusted bolts, which not only increases maintenance costs, but may also delay the maintenance progress due to the difficulty of bolt disassembly, affecting the continuous power supply of the power system.

[0004] Therefore, we propose a push-pull type outdoor high-voltage disconnect switch to address this deficiency in existing technology. Summary of the Invention

Side plates are fixedly installed on both sides of the conductive frame. The upper and lower surfaces of the side plates are in contact with the oppositely installed ball bearings. A mating block is fixedly installed on the side of the conductive frame. A mating groove is opened at the end of conductive post 1. An elastic sheet is installed on the inner wall of the mating groove. The outer surface of the mating block is mated with the inside of the mating groove. An arc-shaped surface is provided on the outer wall of the mating block, and the elastic sheet abuts against the arc-shaped surface.

[0007] Furthermore, a U-shaped frame is fixedly installed on the upper surface of the side plate, a toothed plate is fixedly installed on the side of the U-shaped frame, a shaft bracket is fixedly installed on the inner top of the housing, a rotating gear is rotatably connected to the outer surface of the shaft bracket, the rotating gear meshes with the toothed plate, a slot is opened on the top of the housing, and a shaft drive gear is movably connected inside the slot, the shaft drive gear meshes with the rotating gear, and a motor is fixedly installed at the end of the shaft drive gear.

[0008] Furthermore, a housing is fixedly installed on the upper surface of the housing, and a shaft-driven gear and a motor are respectively installed inside the housing. The shaft-driven gear is rotatably connected to the inside of the housing, and the motor is installed on the upper surface of the housing by bolts.

[0009] Furthermore, a U-shaped support frame is fixedly installed on the outer side of the shaft bracket, and the inner lower surface of the U-shaped support frame slides in contact with the lower surface of the toothed plate.

[0010] Furthermore, mounting grooves are provided on both sides of the base plate, and the base plate is installed by engaging bolts through the mounting grooves. Sliding grooves are provided on both sides of the mounting grooves, and the sliding grooves are located at the ends of the base plate. Protective frames are provided at both ends of the base plate.

[0011] Furthermore, sliders are fixedly installed on both sides of the lower surface of the protective frame, and the outer surface of the sliders is slidably connected to the inside of the groove, with the protective frame covering the mounting groove.

[0012] Furthermore, slots are provided on both sides of the protective frame, and movable stop block one and movable stop block two are slidably connected inside the slots respectively. Limiting grooves are provided at both ends between the mounting groove and the sliding groove, and the limiting grooves are opened on the base plate.

[0013] Furthermore, both ends of the lower surfaces of the first and second movable blocks are fixedly equipped with inserts, which are inserted into the interior of the limiting groove.

[0014] Furthermore, the ball bearings are provided in several groups, and the several groups of ball bearings are arranged at equal intervals along the moving direction of the conductive frame, and the surface of the side plate is in rolling connection with the ball bearings.

[0015] Compared with the prior art, the present invention provides a push-pull type outdoor high-voltage disconnect switch, which has the following advantages:

[0016] 1. This push-pull type outdoor high-voltage disconnect switch adopts a push-pull conductive structure. A motor drives a shaft-driven gear, which in turn meshes with a gear plate, controlling the movement of the conductive frame along the side frame. This achieves precise docking between the docking block and the docking slot. The arc-shaped surface of the outer wall of the docking block cooperates with the elastic sheet on the inner wall of the docking slot, ensuring tight conductive contact, reducing contact resistance, and minimizing energy loss. It also acts as a buffer during docking, preventing damage to components from hard collisions. Simultaneously, multiple sets of equidistant ball bearings installed on the upper and lower surfaces inside the side frame roll against the side plates on both sides of the conductive frame, significantly reducing frictional resistance during frame movement. This makes the switch opening and closing operations smoother, reduces the probability of mechanical failures, and improves operational efficiency. The U-shaped support frame fixed to the outside of the shaft bracket slides against the lower surface of the gear plate, providing stable support for the gear plate's movement and preventing it from shifting or wobbling during meshing. This ensures the accuracy of gear transmission, thereby ensuring a stable conductive frame movement trajectory and improving the overall reliability of the switch operation.

[0017] 2. This push-pull type outdoor high-voltage disconnect switch features protective frames at both ends of the base plate that are slidably connected to the mounting groove via sliders. This precisely covers the mounting groove, effectively preventing outdoor rainwater, dust, and impurities from entering the mounting groove, preventing bolt corrosion or jamming, and ensuring convenient bolt removal during subsequent maintenance. Simultaneously, movable blocks one and two within the slots on both sides of the protective frame are inserted into the limiting grooves on the base plate via bottom inserts. This not only fixes the position of the protective frame, preventing displacement in the outdoor environment, but also further enhances the sealing and protection of the mounting groove, improving the overall resistance to outdoor environmental interference and extending the equipment's service life.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 A push-pull type outdoor high-voltage disconnect switch includes a base plate 1, insulating posts 2, and terminals 3. Insulating posts 2 are installed on both sides of the upper surface of the base plate 1. Terminals 3 are installed at the ends of one set of insulating posts 2, and terminals 4 are installed at the ends of the other set of insulating posts 2. A housing 5 is installed on the outer surface of the opposite ends of terminals 3 and 4. Conductive posts 9 are installed at the ends of terminals 3 and 4, and conductive posts 19 are installed at the ends of terminals 4. A conductive frame 12 is fitted on the outer surface of conductive posts 19. The interior of the housing 5 is fixed on opposite sides. A side frame 10 is installed, with ball bearings 11 installed on both the top and bottom surfaces inside the side frame 10. Side plates 20 are fixedly installed on both sides of a conductive frame 12, with their top and bottom surfaces fitting against the corresponding ball bearings 11. A mating block 17 is fixedly installed on the side of the conductive frame 12. A mating groove 15 is formed at the end of the conductive post 9, and an elastic sheet 16 is installed on the inner wall of the mating groove 15. The outer surface of the mating block 17 mates with the interior of the mating groove 15, and the outer wall of the mating block 17 has an arc-shaped surface 32, with the elastic sheet 16 abutting against the arc-shaped surface 32.

[0029] The conductive frame 12 can slide along the conductive post 19. When sliding, the side plate 20 and the ball bearing 11 inside the side frame 10 roll together to reduce movement resistance. When the conductive frame 12 moves to the designated position, the docking block 17 is inserted into the docking groove 15, and the arc surface 32 contacts and squeezes the elastic sheet 16 to achieve a tight docking between the two.

[0030] Specifically, the rolling engagement of the ball bearing 11 makes the conductive frame 12 move more smoothly and reduces mechanical wear; the elastic docking design of the docking block 17 and the docking groove 15 not only ensures the tightness of the conductive contact and reduces the contact resistance, but also avoids damage to the components from hard collisions and extends the service life of the components.

[0031] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 A U-shaped frame 13 is fixedly installed on the upper surface of the side plate 20, and a toothed plate 14 is fixedly installed on the side of the U-shaped frame 13. A shaft bracket 21 is fixedly installed on the inner top of the housing 5, and a rotating gear 22 is rotatably connected to the outer surface of the shaft bracket 21. The rotating gear 22 meshes with the toothed plate 14. A slot is opened on the top of the housing 5, and a shaft drive gear 8 is movably connected inside the slot. The shaft drive gear 8 meshes with the rotating gear 22, and a motor 7 is fixedly installed at the end of the shaft drive gear 8.

[0032] After the motor 7 starts, it drives the shaft-driven gear 8 to rotate. The shaft-driven gear 8 drives the rotating gear 22 that meshes with it to rotate. The rotating gear 22 then drives the gear plate 14 and the connected U-shaped frame 13, side plate 20 and conductive frame 12 to move through the meshing relationship with the tooth plate 14, thereby realizing the opening and closing action of the switch.

[0033] Specifically, the gear transmission driven by motor 7 replaces the traditional manual operation, improving the automation level and operational accuracy of the switch opening and closing; the stable gear meshing transmission can accurately control the movement distance of the conductive frame 12, ensuring that the docking block 17 and the docking groove 15 are accurately docked, thus improving the reliability of switch operation.

[0034] Please see Figure 2 A housing 6 is fixedly mounted on the upper surface of the housing 5. Inside the housing 6 are a shaft-driven gear 8 and a motor 7. The shaft-driven gear 8 is rotatably connected to the inside of the housing 6, and the motor 7 is mounted on the upper surface of the housing 5 by bolts.

[0035] The housing 6 provides installation and protection space for the shaft-driven gear 8 and the motor 7. The shaft-driven gear 8 rotates stably inside the housing 6, and the motor 7 is fixed to the housing 5 with bolts to ensure stability during operation and prevent component displacement from affecting the transmission effect.

[0036] Specifically, the housing 6 can effectively block outdoor rainwater, dust and other impurities from entering the shaft-driven gear 8 and motor 7, preventing component corrosion or failure and extending the service life of motor 7 and gear; the bolt fixing method of motor 7 facilitates later maintenance and disassembly, reducing maintenance difficulty.

[0037] Please see Figure 3 , Figure 4 and Figure 5 A U-shaped support frame 18 is fixedly installed on the outer side of the shaft bracket 21. The inner lower surface of the U-shaped support frame 18 slides in contact with the lower surface of the toothed plate 14.

[0038] When the toothed plate 14 moves under the drive of the rotating gear 22, its lower surface remains in contact with the inner lower surface of the U-shaped support frame 18 and slides. The U-shaped support frame 18 provides bottom support for the toothed plate 14 and restricts the displacement of the toothed plate 14 in the vertical direction.

[0039] Specifically, the supporting function of the U-shaped support frame 18 can prevent the toothed plate 14 from sagging or shifting due to gravity or gear meshing force during movement, ensuring that the toothed plate 14 and the rotating gear 22 always maintain a good meshing state, avoiding transmission jamming or failure, and improving the stability of the gear transmission system.

[0040] Please see Figure 6 , Figure 7 and Figure 8The base plate 1 has mounting grooves 24 on both sides. The base plate 1 is installed by bolts through the mounting grooves 24. The mounting grooves 24 have sliding grooves 25 on both sides. The sliding grooves 25 are located at the ends of the base plate 1. The base plate 1 has protective frames 23 at both ends.

[0041] During installation, bolts pass through the mounting groove 24 to fix the base plate 1 to the designated mounting surface; the protective frame 23 can be slidably adjusted through the slide groove 25 to cover the mounting groove 24 and protect the bolts in the mounting groove 24.

[0042] Specifically, the design of the mounting groove 24 facilitates the flexible installation and fine-tuning of the base plate 1; the protective frame 23 can prevent rainwater, dust and other elements in the outdoor environment from entering the mounting groove 24, prevent bolts from rusting or getting stuck by impurities, and ensure that the bolts can be easily removed during later maintenance.

[0043] Please see Figure 7 and Figure 8 The lower surface of the protective frame 23 is fixedly mounted on both sides with sliders 27. The outer surface of the sliders 27 is slidably connected to the inside of the groove 25. The protective frame 23 covers the mounting groove 24.

[0044] When the protective frame 23 is moved, the slider 27 on its lower surface slides along the inside of the groove 25, guiding the protective frame 23 to move precisely above the mounting groove 24, thereby covering and protecting the mounting groove 24.

[0045] Specifically, the sliding cooperation between the slider 27 and the slide groove 25 makes the movement of the protective frame 23 smoother and the positioning more accurate, ensuring that it can completely cover the mounting groove 24; at the same time, the sliding structure facilitates the quick movement of the protective frame 23 according to maintenance needs in the future, improving maintenance convenience.

[0046] Please see Figure 7 and Figure 8 The protective frame 23 has slots 28 on both sides. Movable stop blocks 29 and 30 are slidably connected inside the slots 28. Limiting grooves 26 are provided at both ends between the mounting groove 24 and the sliding groove 25, and these limiting grooves 26 are located on the base plate 1.

[0047] After the protective frame 23 moves to the position covering the mounting slot 24, the movable stop 1 29 and movable stop 2 30 slide along the slot 28 so that the bottom of both are aligned with the limiting slot 26, in preparation for fixing the position of the protective frame 23.

[0048] Specifically, the sliding design of movable stop 1 29 and movable stop 2 30 provides adjustable space for fixing the protective frame 23, ensuring effective fixing in different installation scenarios; the setting of the limiting groove 26 clarifies the fixed position of the movable stop and improves the fixing accuracy.

[0049] Please see Figure 7 and Figure 8 Both ends of the lower surface of movable stop 29 and movable stop 30 are fixedly installed with inserts 31, which are inserted into the interior of the limiting groove 26.

[0050] After adjusting the positions of movable stop 1 29 and movable stop 2 30, insert the insert 31 on their lower surfaces into the limiting groove 26. Through the insertion and engagement of the insert 31 with the limiting groove 26, the sliding of the protective frame 23 along the slide groove 25 is restricted, thereby fixing the position of the protective frame 23.

[0051] Specifically, the insertion and fixing method of the plug 31 and the limiting groove 26 can effectively prevent the protective frame 23 from shifting under the influence of outdoor wind, vibration and other factors, and ensure that it always covers the mounting groove 24; at the same time, the plug structure is easy to disassemble and does not affect the movement operation of the protective frame 23 during later maintenance.

[0052] Please see Figure 3 and Figure 4 The ball bearings 11 are provided in several sets, and the several sets of ball bearings 11 are equidistantly arranged along the moving direction of the conductive frame 12. The surface of the side plate 20 is in rolling contact with the ball bearings 11.

[0053] Several sets of equidistantly arranged balls 11 are evenly distributed on the upper and lower surfaces inside the side frame 10. When the side plate 20 moves with the conductive frame 12, the surface of the side plate 20 contacts the balls 11 and drives the balls 11 to roll, converting the sliding friction between the side plate 20 and the side frame 10 into rolling friction.

[0054] Specifically, the equidistantly arranged balls 11 provide uniform support for the side plate 20, preventing uneven force on the side plate 20 and thus avoiding deformation. The rolling friction design significantly reduces the frictional resistance when the conductive frame 12 moves, reduces mechanical wear, makes the switch opening and closing operation easier and smoother, and reduces the probability of mechanical failure.

[0055] Working principle and usage steps: The base plate 1 serves as the foundation for the device and is fixed to the outdoor mounting surface by bolts through the mounting slots 24 on both sides, providing stable support for the components above; the insulating columns 2 on both sides of the upper surface of the base plate 1 support terminal 3 and terminal 4 respectively, realizing the initial insulation of the high voltage circuit and the fixing of the wiring terminals; the opposite ends of terminal 3 and terminal 4 form a closed space through the housing 5, protecting the internal conductive components from outdoor environmental interference;

[0056] Terminal 1 3 is connected to conductive post 1 9, and terminal 2 4 is connected to conductive post 2 19. A slidable conductive frame 12 is fitted on the outer surface of conductive post 2 19. The conductive frame 12 and conductive post 2 19 maintain conductive contact, forming a key movable component for circuit switching. When the conductive frame 12 is connected to conductive post 1 9, the circuit is connected; when separated, the circuit is disconnected.

[0057] The device is equipped with a motor 7 as a power source. The output end of the motor 7 is connected to a shaft-driven gear 8. The shaft-driven gear 8 meshes with a rotating gear 22 on the top shaft bracket 21 inside the housing 5. After the motor 7 starts, it drives the shaft-driven gear 8 to rotate, which in turn drives the rotating gear 22 to rotate synchronously, converting the rotational power of the motor 7 into gear transmission power.

[0058] The rotating gear 22 meshes with the side toothed plate 14 of the U-shaped frame 13 on the two side plates 20 of the conductive frame 12. The rotational motion of the rotating gear 22 is converted into the linear motion of the toothed plate 14 through tooth meshing, which drives the U-shaped frame 13, the side plates 20 and the conductive frame 12 to move in the set direction, thereby realizing the opening and closing action of the switch.

[0059] Multiple sets of equidistant ball bearings 11 are installed on the upper and lower surfaces of the side frame 10 inside the housing 5. The upper and lower surfaces of the side plate 20 are in contact with the ball bearings 11. When the conductive frame 12 moves, the ball bearings 11 roll to reduce the frictional resistance between the side plate 20 and the side frame 10, ensuring smooth movement. At the same time, the U-shaped support frame 18 on the outside of the shaft bracket 21 slides in contact with the lower surface of the toothed plate 14, providing bottom support for the toothed plate 14, preventing the toothed plate 14 from sagging or shifting, and ensuring gear meshing accuracy.

[0060] As the conductive frame 12 moves toward the conductive post 9, the mating block 17 on its side gradually approaches the mating groove 15 at the end of the conductive post 9. The arc-shaped surface 32 on the outer wall of the mating block 17 first contacts the elastic sheet 16 on the inner wall of the mating groove 15. As the conductive frame 12 continues to move, the arc-shaped surface 32 squeezes the elastic sheet 16 to cause it to undergo elastic deformation until the mating block 17 is fully inserted into the mating groove 15. Under its own elastic action, the elastic sheet 16 tightly adheres to the surface of the mating block 17, ensuring the tightness of the conductive contact, reducing the contact resistance, and ensuring stable circuit conduction.

[0061] The protective frames 23 at both ends of the base plate 1 are slidably connected to the sliding grooves 25 at the ends of the base plate 1 via the lower surface sliders 27. After installation, the protective frames 23 are pushed to move along the sliding grooves 25 so that they cover the mounting grooves 24, preventing rainwater, dust and other impurities from entering the mounting grooves 24 and preventing bolt corrosion.

[0062] The movable blocks 29 and 30 inside the slots 28 on both sides of the protective frame 23 can slide along the slots 28. After being adjusted to the corresponding position of the upper limit slot 26 on the base plate 1, the inserts 31 on the lower surface of the movable blocks 29 and 30 are inserted into the limit slot 26 to fix the position of the protective frame 23, preventing it from shifting due to outdoor wind and vibration, and ensuring a long-lasting and stable protective effect.

[0063] In this application, the device is equipped with a PLC controller, a control panel, and a power supply battery. The PLC controller receives command signals from the control panel to control the start, stop, forward and reverse rotation of the motor 7, thereby controlling the moving direction and distance of the conductive frame 12, realizing the automated control of the switch opening and closing. The power supply battery provides stable power to the motor 7 and control components, ensuring that the device can still operate normally when there is no external power supply outdoors. This is an existing technology for the control and operation of equipment.

[0064] The beneficial effect is that the motor 7 drives the shaft transmission gear 8, which drives the rotating gear 22 to mesh with the toothed plate 14, and controls the conductive frame 12 to move along the side frame 10, so as to achieve precise docking of the docking block 17 and the docking groove 15. The arc-shaped surface 32 of the docking block 17 cooperates with the elastic sheet 16 to ensure tight conductivity and reduce contact resistance; multiple sets of equidistant balls 11 inside the side frame 10 roll and fit against the side plate 20 to reduce friction, making opening and closing smoother and reducing the probability of mechanical failure; the U-shaped bearing frame 18 on the outside of the shaft bracket 21 slides against the lower surface of the toothed plate 14 to prevent the toothed plate 14 from shifting, ensuring accurate gear transmission, ensuring stable movement trajectory of the conductive frame 12, and improving overall operational reliability; the protective frames 23 at both ends of the base plate 1 are slidably connected to the slide groove 25 through the slider 27, covering the mounting groove 24, blocking impurities, and preventing bolt corrosion; the inserts 31 of the movable stop block 1 29 and movable stop block 2 30 are inserted into the limit groove 26 to fix the protective frame 23, enhance sealing protection, and extend the equipment life.
