Description

Technical Field

[0001] This utility model relates to an energy storage pulse power supply, specifically an energy storage pulse power supply that can be quickly switched. Background Technology

[0002] The demolition of urban concrete beams, as well as the pre-fracture of rocks in tunnels and mines, all require the pre-fracture of rock or concrete to facilitate further processing.

[0003] During rock breaking, a high-voltage energy storage pulse power supply discharges to a controllable shock wave transducer, forming a short-pulse high voltage between the discharge electrodes. This high voltage breaks down the liquid medium, creating a plasma channel. When electrical energy is injected into this plasma channel, it generates high temperature and pressure, causing the channel to expand outward and produce a pulsed pressure wave. The high-voltage energy storage pulse power supply discharges via a charge / discharge switch. It typically consists of capacitors, batteries, or other energy storage components and can provide high-power pulses for short periods. Energy storage pulse power supplies are widely used in applications requiring very high power but short durations. During operation, the energy storage device charges, and when output is needed, the stored energy is released into the load circuit in the form of high-power pulses through a pulse modulation circuit.

[0004] Current energy storage pulse power supplies cannot achieve rapid switching during use. For example, when the connected power grid fails, the energy storage pulse power supply cannot provide power in time and requires manual power supply by the operator, resulting in a long power outage time, slow response time, and affecting the use effect. Utility Model Content

[0005] The purpose of this invention is to provide a fast-switching energy storage pulse power supply to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fast-switching energy storage pulse power supply includes a power cabinet and single power supply mechanisms stacked from top to bottom in the cavity of the power cabinet. A fast-switching structure is provided in the cavity at the bottom of the power cabinet.

[0008] The fast switching structure includes an input mechanism disposed on one side of the power cabinet cavity, an output mechanism disposed opposite to the input mechanism in the power cabinet cavity, and a fourth cable disposed between the input mechanism and the output mechanism for closing or disconnecting the connection between the two. The output mechanism is connected to a disconnection mechanism, and the disconnection mechanism is connected to the stacked single power supply mechanism.

[0009] The fourth cable is used to control the closing or opening of the input mechanism and the output mechanism. When the input mechanism and the output mechanism are closed through the fourth cable, the fourth cable abuts against the opening mechanism to disconnect it from the output mechanism. When the input mechanism and the output mechanism are disconnected through the fourth cable, the fourth cable breaks off the abutment against the opening mechanism, and at this time the opening mechanism is closed with the output mechanism.

[0010] The rapidly switchable energy storage pulse power supply described above: The input mechanism includes a high-voltage connector installed on one side of the power cabinet, a power supply cable with one end connected to the high-voltage connector, and a first cable with one end connected to the high-voltage connector.

[0011] An electromagnetic adsorption mechanism is provided on the outer wall of the other end of the first cable, and an interlocking groove is provided on the same end of the electromagnetic adsorption mechanism.

[0012] A fixing ring is fitted onto the first cable, and a first insulator is fixedly mounted on the fixing ring. A rotating seat is provided on the top of the first insulator.

[0015] A second insulator is fixedly installed on the second cable, and a U-shaped seat is fixedly installed on the top of the second insulator.

[0016] The rapidly switchable energy storage pulse power supply described above: the disconnection mechanism includes a connecting copper plate rotatably connected at one end to a rotating base and a third cable connected at one end to the connecting copper plate, the third cable being connected to a stacked single power supply mechanism.

[0017] An insulating shell is fitted onto the connecting copper plate, and the other end of the connecting copper plate is engaged with the U-shaped seat.

[0018] The rapidly switchable energy storage pulse power supply described above: a conductive copper pillar is provided at one end of the fourth cable, and an insulating tube is fixedly provided on the fourth cable around the conductive copper pillar;

[0019] The conductive copper pillar is inserted into the sliding cavity, the insulating tube is slidably inserted into the insulating cavity, the two sides of the fourth cable are fixedly connected to the insertion shaft, and the other end of the fourth cable is provided with a fitting ball head, which is fitted into the fitting groove.

[0020] An abutting block is fixed on the outer wall of the fourth cable at the cross intersection with the plug shaft. A sliding groove is horizontally opened on the abutting block, and two springs are fixedly installed on the abutting blocks on both sides of the sliding groove.

[0021] As described above, the energy storage pulse power supply with rapid switching capability: the fourth cable is mounted on a U-shaped mounting bracket, which is detachably installed in the cavity at the bottom of the power cabinet, and a sliding hole is provided at the top center of the mounting bracket;

[0022] The fourth cable is symmetrically fixed with blocks, and a connecting block is fixedly connected between the two blocks. The fixing frame is symmetrically provided with insertion holes.

[0023] The sliding hole is slidably connected to the sliding groove on the abutment pin, the bottom of the abutment pin is rotatably connected to an abutment wheel, and the top of the abutment pin abuts against the insulating shell.

[0024] As described above, the energy storage pulse power supply can be quickly switched: the abutting wheel rotates and abuts against the abutting inclined block, the stop block is fixedly set at the other end of the spring, the connecting block is slidably connected in the slide groove, and the insertion hole is slidably inserted into the insertion shaft.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By connecting the rapid switching structure in parallel with the power grid, the structure can respond quickly when the grid fails. The stacked single-power supply mechanisms inside the power cabinet ensure continuous power supply, reducing outage time and improving response speed. Furthermore, when grid power is restored, the single-power supply mechanism can be disconnected, achieving automated and rapid disconnection and closure. A fourth cable, slidably adjustable between the input and output mechanisms, controls the closed state between them. When the input and output mechanisms are disconnected, the disconnecting mechanism remains connected to the output mechanism, ensuring power supply. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] Please see Figures 1-12In this embodiment of the present invention, a fast-switching energy storage pulse power supply includes a power cabinet 1 and single power supply mechanisms 2 stacked from top to bottom in the cavity of the power cabinet 1. A fast-switching structure is provided in the cavity at the bottom of the power cabinet 1.

[0042] The fast switching structure includes an input mechanism disposed on one side of the power cabinet 1 cavity, an output mechanism disposed opposite to the input mechanism in the power cabinet 1 cavity, and a fourth cable 20 disposed between the input mechanism and the output mechanism for closing or disconnecting the connection between the two. The output mechanism is connected to the disconnection mechanism, and the disconnection mechanism is connected to the stacked single power supply mechanism 2.

[0043] The fourth cable 20 is used to control the closing or opening of the input mechanism and the output mechanism. When the input mechanism and the output mechanism are closed through the fourth cable 20, the fourth cable 20 abuts against the opening mechanism to disconnect it from the output mechanism. When the input mechanism and the output mechanism are disconnected through the fourth cable 20, the fourth cable 20 disconnects from the opening mechanism, and at this time the opening mechanism is closed with the output mechanism.

[0044] In this embodiment, the power supply from the input mechanism attracts and closes the fourth cable 20 with the input mechanism. At this time, the fourth cable 20 acts between the input and output mechanisms, enabling them to conduct. The input mechanism is connected to the power grid, and the power transmitted by the output mechanism is supplied from the input mechanism. When the power grid is de-energized, the input mechanism loses its attraction effect, and the fourth cable 20 moves towards the output mechanism, disconnecting the input and output mechanisms. The disconnecting mechanism loses the resistance of the fourth cable 20, thus making it conduction-connected with the output mechanism. Since the disconnecting mechanism is connected to the stacked single power supply mechanism 2, the power transmitted by the output mechanism comes from the electrical energy stored in the stacked single power supply mechanism 2. When the input mechanism resumes power supply, the fourth cable 20 moves to the input mechanism, contacting the disconnecting mechanism to disconnect it, and the input and output mechanisms become conductive. Through the action of the rapid switching structure, the power cabinet 1 and the single power supply mechanism 2 can be connected in parallel in the power supply, enabling timely response during power outages or resurgences and improving the response rate.

[0045] As a further embodiment of this utility model, the input mechanism includes a high-voltage connector 4 installed on one side of the power cabinet 1, a power supply cable 3 connected to the high-voltage connector 4 at one end, and a first cable 5 connected to the high-voltage connector 4 at one end.

[0046] An electromagnetic adsorption mechanism 6 is provided on the outer wall of the other end of the first cable 5, and an interlocking groove 7 is provided on the same end of the electromagnetic adsorption mechanism 6.

[0047] A fixing ring 8 is installed on the first cable 5, and a first insulator 9 is fixedly installed on the fixing ring 8. A rotating seat 10 is provided on the top of the first insulator 9.

[0048] In this embodiment, one end of the power supply cable 3 is connected to the power grid to meet the power grid supply requirements. The electromagnetic adsorption mechanism 6 provided at one end of the first cable 5 can generate electromagnetic adsorption force when the first cable 5 is powered, which can meet the requirements of rapid switching. The electromagnetic adsorption mechanism 6 is a publicly available technical means and will not be described in detail here. The first cable 5 is provided with a first insulator 9 through a fixing ring 8, which can disconnect the conduction between the rotating seat 10 and the first cable 5 and improve the insulation effect.

[0049] As a further embodiment of this utility model, the output mechanism includes another high-voltage connector 4 installed on the other side of the power cabinet 1, an output cable 11 connected to the high-voltage connector 4 at one end, and a second cable 12 connected to the high-voltage connector 4 at one end.

[0050] The other end of the second cable 12 is provided with a sliding cavity 13, and an insulating cavity 14 is provided on the second cable 12 surrounding the sliding cavity 13.

[0051] A second insulator 15 is fixedly installed on the second cable 12, and a U-shaped seat 16 is fixedly installed on the top of the second insulator 15.

[0052] In this embodiment, the output cable 11 is connected to external electrical equipment. The sliding cavity 13 on the second cable 12 is enclosed by the insulating cavity 14, which can achieve the effect of insulation. The second insulator 15 on the second cable 12 is conductive to it, and the U-shaped seat 16 on the second insulator 15 is conductive to the second insulator 15. Therefore, the second cable 12 is also conductive to the U-shaped seat 16, which meets the requirement of timely switching to power supply after power failure and improves the use effect.

[0053] As a further embodiment of this utility model, the disconnection mechanism includes a connecting copper plate 17 rotatably connected at one end to the rotating seat 10 and a third cable 18 connected at one end to the connecting copper plate 17. The third cable 18 is connected to the stacked single power supply mechanism 2.

[0054] An insulating shell 19 is fitted onto the connecting copper plate 17, and the other end of the connecting copper plate 17 is engaged with the U-shaped seat 16.

[0055] In this embodiment, one end of the connecting copper plate 17 is rotatably connected to the rotating seat 10, allowing the connecting copper plate 17 to rotate and tilt around the rotating connection point of the rotating seat 10. The other end of the connecting copper plate 17 is engaged with the U-shaped seat 16. One end of the connecting copper plate 17 located on the rotating seat 10 is connected to the third cable 18, which is connected to the stacked single power supply mechanism 2. When the connecting copper plate 17 is engaged with the U-shaped seat 16, the electrical energy stored in the single power supply mechanism 2 is transmitted to the output mechanism. The insulating shell 19 surrounding the middle part of the connecting copper plate 17 can achieve the insulation effect of the connecting copper plate 17.

[0056] As a further embodiment of this utility model, a conductive copper pillar 21 is provided at one end of the fourth cable 20, and an insulating tube 22 is fixedly provided on the fourth cable 20 around the conductive copper pillar 21.

[0057] The conductive copper pillar 21 is inserted into the sliding cavity 13, the insulating tube 22 is slidably inserted into the insulating cavity 14, the two sides of the fourth cable 20 are fixedly connected with the insertion shaft 23, and the other end of the fourth cable 20 is provided with the fitting ball head 24, which is fitted into the fitting groove 7.

[0058] A contacting block 25 is fixed on the outer wall of the fourth cable 20 at the cross intersection with the plug shaft 23. A sliding groove 26 is horizontally opened on the contacting block 25. Two springs 27 are fixedly installed on one end of the contacting blocks 25 on both sides of the sliding groove 26.

[0059] In this embodiment, when the fourth cable 20 is slidably adjusted, the conductive copper pillar 21 is inserted into the sliding cavity 13. When the fitting ball head 24 at one end of the fourth cable 20 is fitted with the fitting groove 7, the input mechanism and the output mechanism are connected. When the fitting ball head 24 is disconnected from the fitting groove 7, the input mechanism and the output mechanism are disconnected. When the fourth cable 20 slides, the insulating tube 22 around the conductive copper pillar 21 is slidably inserted into the insulating cavity 14. The insulating tube 22 can achieve the effect of insulating and sealing the conductive copper pillar 21 when it is slidably inserted and adjusted.

[0060] As a further embodiment of this utility model, the fourth cable 20 is mounted on a U-shaped fixing bracket 28, which is detachably installed in the cavity at the bottom of the power cabinet 1. A sliding hole 29 is provided at the center of the top of the fixing bracket 28.

[0061] The fourth cable 20 is symmetrically fixed with a stop block 30, and a connecting block 31 is fixedly connected between the two stop blocks 30. The fixing frame 28 is symmetrically provided with a plug hole 32.

[0062] The sliding hole 29 is slidably connected to the sliding groove 34 opened on the abutment pin 33. The bottom of the abutment pin 33 is rotatably connected to the abutment wheel 35. The top of the abutment pin 33 abuts against the insulating shell 19. The abutment wheel 35 rotates and abuts against the abutment inclined block 25. The stop block 30 is fixedly set to the other end of the spring 27. The connecting block 31 is slidably connected in the sliding groove 26. The insertion hole 32 is slidably inserted into the insertion shaft 23.

[0063] In this embodiment, the spring 27 acts between the stop block 30 and the abutting inclined block 25, which can compress the spring 27 to maintain its rebound force when the fourth cable 20 moves and adjusts. Therefore, when the electromagnetic adsorption mechanism 6 is energized and generates electromagnetic adsorption force to attract the fourth cable 20, so that the fitting ball head 24 at one end of the fourth cable 20 is fitted with the fitting groove 7, the fourth cable 20 moves towards one end of the electromagnetic adsorption mechanism 6, so that the spring 27 receives the compression force to maintain its rebound. At this time, the abutting inclined block 25 abuts against the abutting wheel 35. Since the inclined surface of the abutting inclined block 25 faces the second cable 12, when the fourth cable 20 moves towards the electromagnetic adsorption mechanism 6, the abutting inclined block 25 will cause the abutting wheel 35 to be abutted and move upward. Since the abutting pin 33 is limited and inserted into the sliding hole through the sliding groove 34, the abutting pin 33 is fixed and inserted into the sliding hole. Within 29, the abutment pin 33 can only slide and insert vertically. Therefore, when the abutment pin 33 rises, it will abut against the insulating shell 19, causing the connecting copper plate 17 to rotate around the rotation connection point with the rotating seat 10. At this time, the connecting copper plate 17 disconnects from the U-shaped seat 16, meeting the power grid supply requirements. When the power grid fails, the electromagnetic attraction force of the electromagnetic attraction mechanism 6 disappears, the compressed spring 27 rebounds, and the fourth cable 20 resets. At this time, the abutment block 25 loses its contact with the abutment pin 33, the abutment pin 33 falls, and the connecting copper plate 17 rotates and resets under the influence of gravity. One end of the connecting copper plate 17 engages with the U-shaped seat 16. At this time, the stacked single power supply mechanism 2 can supply power to the output mechanism through the third cable 18 and the connecting copper plate 17, meeting the requirements for rapid switching.

[0064] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
