Description

Technical Field

[0001] This invention relates to the field of power distribution technology, and more specifically to a method for rapid connection during uninterrupted power distribution operations. Background Technology

[0002] During the operation and maintenance of power distribution systems, to ensure continuous power supply to critical loads (such as hospitals, data centers, communication base stations, and transportation hubs), uninterrupted power supply (UDS) is typically required for maintenance and switching. Emergency power generation vehicles, as mobile backup power equipment, can temporarily connect to the power distribution system to continuously supply power to loads during main power supply maintenance, failures, or switching, thereby achieving uninterrupted power supply and avoiding economic losses and safety hazards caused by power outages.

[0003] Chinese utility model patent CN211182684U discloses a wall-mounted generator vehicle quick-connection device, including a lifting assembly. A positioning seat is fixed to the lifting assembly, and an access terminal is installed on the inner bottom wall of the positioning seat. The access terminal is connected to a substation via a cable. Locking assemblies are movably connected to corresponding sides of the positioning seat. A control board is movably connected to one side of the lifting assembly, and the control board is electrically connected to the locking assembly. The locking assembly includes a voltage sensor, a telescopic groove, a telescopic cylinder, a locking block, a timer, and a PLC controller. The voltage sensor is mounted on the cable. Telescopic grooves are formed on corresponding sides of the positioning seat, and locking blocks are movably connected inside the telescopic grooves. This utility model solves the problems of difficult wiring of emergency generator vehicles, difficulty in digging cable trench foundations, and danger of operation in windy and rainy weather, greatly improving the safety of use.

[0004] However, in the aforementioned patents, the interface of the positioning base lacks any active or passive protection structure, leaving the connection end exposed for extended periods. On one hand, outsiders (especially children) can easily insert their fingers or foreign objects into the positioning base, posing a significant risk of direct contact with live terminals and posing a substantial safety hazard. On the other hand, environmental pollutants such as dust, moisture, and rainwater can easily enter the positioning base and adhere to the surface of the connection end, thereby affecting the stability and reliability of the electrical connection and potentially causing problems such as poor contact or short circuits.

[0005] In addition, the solution requires the use of electrical components (telescopic cylinders) to clamp the insertion connector to prevent loosening, and the addition of electrical components can easily lead to increased energy consumption and maintenance difficulties. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention aims to provide a rapid connection method for uninterrupted power distribution operations. To solve these problems, this invention employs the following technical solution: A method for rapid connection during uninterrupted power distribution operations includes the following steps: an emergency power generation vehicle is driven to the vicinity of a positioning seat, a fence is erected near the emergency power generation vehicle, a plug is provided on the connection cable of the emergency power generation vehicle, two connection holes are provided on the plug, a connection channel and a transmission cavity are provided on the positioning seat, two terminals are fixedly connected to the inner wall of the connection channel, a protective mechanism is provided in the connection channel, a linkage mechanism is provided in the transmission cavity, and the protective mechanism and the linkage mechanism are connected.

The transmission mechanism includes an inclined block, a connecting strip, an inclined surface, and an elastic element 2. The inclined block is slidably connected to one of the protruding pillars and extends to the outside of the protruding pillar. The inclined block is connected to the inner wall of the protruding pillar through the elastic element 2.

The slide bar is connected to the inner wall of the transmission cavity through an elastic element. A pull rod is fixedly connected to the slide bar and extends to the outside of the positioning seat. The limiter, the elastic damping block, and the two permanent magnets are all fixedly connected to the inner wall of the transmission cavity. The elastic damping block and the slide bar abut against each other. A locking groove is provided on the limiter. Pushing the plug against the protective plate causes the protective plate and the slide bar to slide to a preset distance. The protective plate then automatically slides on the slide bar, thereby releasing the protection of the connection channel.

[0008] Optionally, the plug is provided with a limiting protrusion, and a limiting groove is provided in the connection channel. When the plug is inserted into the connection channel, the limiting protrusion is inserted into the limiting groove to guide the movement of the plug.

[0012] Optionally, the emergency power generation vehicle is equipped with an automatic winding device to store the connecting cables.

[0013] Optionally, the connecting hole on the plug can be shielded and protected by a cover, and the cover can be removed before the plug and the positioning seat are connected.

[0014] Optionally, a warning light is installed on the fence, which flashes to alert others not to approach.

After the plug is inserted, the protective mechanism provides a passive anti-loosening constraint to prevent it from coming loose. It can achieve stable fixation without the need for additional electrically driven locking components, resulting in a simpler structure and higher reliability. Attached Figure Description

[0023] This invention is applied to the uninterrupted power supply connection of the power distribution system of emergency power generation vehicles.

[0024] To protect the positioning seat 4 before connecting the emergency power generation vehicle and to prevent loosening after connecting the emergency power generation vehicle, the following technical solution is provided.

[0025] like Figures 1-7As shown, a rapid connection method for uninterrupted power distribution operations includes the following steps: an emergency generator vehicle is driven to the vicinity of a positioning seat 4, a fence is erected near the emergency generator vehicle, a plug 1 is provided on the connection cable of the emergency generator vehicle, two connection holes 2 are provided on the plug 1, a connection channel 5 and a transmission cavity 6 are provided on the positioning seat 4, two terminals 8 are fixedly connected to the inner wall of the connection channel 5, a protective mechanism is provided in the connection channel 5, and a linkage mechanism is provided in the transmission cavity 6, the protective mechanism and the linkage mechanism are connected; the terminals 8 are preferably made of a new type of electrical contact precious metal material, such as AgSnO2-based composite precious metal material, which has low contact resistance, resistance to arc erosion and oxidation resistance.

[0026] Insert plug 1 into connection channel 5, the protective mechanism releases the protection of connection channel 5, and each terminal 8 is inserted into each connection hole 2 to complete the connection.

[0027] Through the above overall structure, the insertion of plug 1 can simultaneously trigger the coordinated operation of the protective mechanism and the linkage mechanism, thereby achieving both rapid electrical connection and safety protection and anti-loosening fixation functions.

[0028] For further details of the protective mechanism and the transmission mechanism, the protective mechanism includes a protective plate 9, on which a permanent magnet 23 is embedded, and two protruding posts 10 are provided on the protective plate 9. Two transmission mechanisms are provided inside the protective plate 9. The protective plate 9 is used to shield and protect the terminal 8, preventing the terminal 8 from being exposed for a long time, and at the same time providing a basic structure for subsequent automatic unlocking and anti-loosening clamping.

[0029] The transmission mechanism includes an inclined block 18, a connecting strip 19, an inclined nipple 20, and an elastic element 22. The inclined block 18 is slidably connected to one of the protrusions 10 and extends to the outside of the protrusion 10. The inclined block 18 is connected to the inner wall of the protrusion 10 through the elastic element 22. The connecting strip 19 and the inclined nipple 20 are both slidably connected to the protective plate 9. The inclined block 18 is fixedly connected to the inclined nipple 20 through the connecting strip 19 and the inclined nipple 20. The inclined nipple 20 extends to the outside of the protective plate 9. The linkage mechanism includes a slide bar 11, a limiter 14, an elastic damping block 15, and a permanent magnet 16. The slide bar 11 is slidably connected to the inner wall of the transmission cavity 6, and the protective plate 9 is slidably connected to the slide bar 11. The slide bar 11 is connected to the inner wall of the transmission cavity 6 through an elastic element 12. A pull rod 13 is fixedly connected to the slide bar 11 and extends to the outside of the positioning seat 4. The limiter 14, the elastic damping block 15, and the two permanent magnets 16 are all fixedly connected to the inner wall of the transmission cavity 6. The elastic damping block 15 and the slide bar 11 abut against each other. A locking groove 21 is provided on the limiter 14. The transmission mechanism is used to convert the insertion force of the plug 1 into the unlocking and displacement action of the protective plate 9, thereby achieving a controlled opening effect where the protection is only released when the plug is correctly inserted.

[0030] After the plug 1 is pushed to the protective plate 9, the protective plate 9 and the slide bar 11 slide to a preset distance. The protective plate 9 then slides automatically on the slide bar 11, thereby releasing the protection of the connection channel 5.

[0031] Based on the above scheme, in some embodiments, the plug 1 is provided with a limiting protrusion 3, and the connection channel 5 is provided with a limiting groove 7. When the plug 1 is inserted into the connection channel 5, the limiting protrusion 3 is inserted into the limiting groove 7 to guide the movement of the plug 1.

[0032] To facilitate the movement of the inclined nipple 20, the outer wall of the limiter 14 is provided with an inclined surface. When the inclined nipple 20 and the inclined surface on the limiter 14 come into contact, the inclined surface will drive the inclined nipple 20 to retract into the protective plate 9.

[0033] Preferably, a magnetic barrier plate 17 is fixed between the two permanent magnets 16, which blocks the magnetic field between the two permanent magnets 16. The magnetic barrier plate 17 is used to prevent mutual interference of magnetic fields, thereby ensuring that the adsorption and repulsion actions of the protective plate 9 under different working conditions are more stable and controllable.

[0034] It is worth noting that the different inclined planes 20 have different heights and different lengths.

[0035] In one optional embodiment of the present invention, the emergency power generation vehicle is equipped with an automatic winding device for storing the connecting cables.

[0036] The cover is used to shield and protect the connection hole 2 on the plug 1. The cover is removed before the plug 1 and the positioning seat 4 are connected. The cover is used to seal and protect the connection hole 2 when not in use, preventing dust, moisture and other contaminants from entering the plug.

[0037] Regarding the warning function, optionally, a warning light can be installed on the fence, emitting a flashing light to alert others not to approach. A speaker can also be installed on the fence to play a warning sound to alert others not to approach.

[0038] Implementation process: In the initial state, the protective plate 9 and the inner wall of the transmission cavity 6 are in contact, all the inclined plates 20 are inserted into the locking groove 21 to limit the protective plate 9, and the elastic element 12 is stretched.

[0039] Pull out the connecting cable from the emergency generator vehicle, remove the cover of plug 1 from the connecting cable, insert plug 1 into the connecting channel 5, and guide the limiting protrusion 3 into the limiting groove 7. First, insert the two protrusions 10 into the two connecting holes 2 respectively. The inner wall of the connecting hole 2 pushes the inclined surface of the inclined block 18, thereby causing the inclined block 18 to retract into the protrusion 10 against the elastic force of the second elastic element 22, thereby driving the connecting strip 19 and the inclined surface 20 to move. The inclined surface 20 disengages from the locking groove 21, and the limiter 14 releases the limit on the protective plate 9 and the slide strip 11. Because the elastic damping block 15 squeezes the slide strip 11, the frictional force of the elastic damping block 15 on the slide strip 11 is greater than the rebound force of the first elastic element 12, and the slide strip 11... It will not immediately spring back automatically. One end of the plug 1 abuts against the protective plate 9. The plug 1 pushes the protective plate 9 towards the terminal 8, so that the inclined surface 20 is not aligned with the locking groove 21. After the slide bar 11 moves to disengage and abuts against the elastic damping block 15, the elastic element 12 quickly contracts. The slide bar 11 and the protective plate 9 move quickly. The protective plate 9 moves to the side of a permanent magnet 16 near the terminal 8. The permanent magnet 16 magnetically attracts the permanent magnet 23 on the protective plate 9, so that the protective plate 9 moves along the slide bar 11 towards the permanent magnet 16. The protective plate 9 automatically releases the blockage of the connection channel 5 so that the plug 1 can approach the terminal 8 and the two terminals 8 can be inserted into the two connection holes 2 for electrical connection.

[0040] Then, pull the lever 13 to move the slide bar 11 and the protective plate 9 in the opposite direction. The elastic element 12 is stretched. When the slide bar 11 and the elastic damping block 15 come into contact, the friction force of the elastic damping block 15 on the slide bar 11 is greater than the rebound force of the elastic element 12. The slide bar 11 will not automatically rebound and will remain in its current position. The permanent magnet 23 on the protective plate 9 is magnetically repelled by a permanent magnet 16 away from the terminal 8. The protective plate 9 presses against the outer wall of the plug 1, thereby fixing the plug 1 and preventing it from loosening and coming off.

[0041] When it is necessary to disconnect the electrical connection between plug 1 and terminal 8, simply pull plug 1 out of connection channel 5. The protective plate 9 is repelled by the magnetic repulsion of permanent magnet 16. The protective plate 9 slides to abut against the inner wall of connection channel 5. Pulling pull rod 13 moves slide bar 11 and protective plate 9 away from terminal 8. After the inclined surface of inclined nipple 20 abuts against the inclined surface on limiter 14, inclined nipple 20 will overcome the elastic force of elastic element 22 and retract into protective plate 9. When inclined nipple 20 is aligned with locking groove 21, inclined nipple 20 is inserted into locking groove 21 under the action of elastic element 22, thereby limiting protective plate 9 and preventing others from pushing protective plate 9 with their fingers, and preventing others from abutting terminal 8 and causing electric shock hazard.

[0042] Beneficial effects of this invention: By setting up a protective plate 9, the protective plate 9 can shield and protect the terminal 8, thereby preventing the terminal 8 from being exposed for a long time, effectively preventing personnel from accidentally touching live parts, improving safety, and reducing the entry of external pollutants such as dust and moisture into the connection channel 5, ensuring the stability and reliability of the electrical connection. The protective plate 9, together with the linkage mechanism, forms a controlled unlocking structure. Even if an outsider inserts their finger directly into the connection channel 5, they cannot directly push the protective plate 9 to move, thereby avoiding human error that could cause the protection to fail. This effectively prevents fingers from coming into contact with the terminal 8 and further reduces the risk of electric shock. The protective plate 9 can be released from the protection of the connection channel 5 and the terminal 8 by using the plug 1 with the appropriate shape to push it, and the process of releasing the protection is simple and highly interconnected. After the plug 1 is inserted, the protective plate 9 continuously presses the outer wall of the plug 1 under the action of magnetic force and linkage mechanism, thereby forming a passive anti-loosening constraint on the plug 1 to prevent loosening. Stable fixation can be achieved without additional electric drive locking components, making the structure simpler and more reliable.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
