[0002] A converter is an electrical device that can convert electrical energy from one form to another. It is mainly used to achieve the conversion of electrical energy parameters such as voltage, current, frequency, and phase to meet the needs of different electrical equipment or power systems. Therefore, in modern power systems, converters play a vital role, ensuring the effective transmission, stable supply, and efficient utilization of electricity.

[0003] In the prior art, during high-power or long-distance power transmission, multiple converters are required to work together, and the existing converters have some problems in the actual working process. For example, a DC / DC converter with publication number CN106059287B can achieve cooling and heat dissipation of the converter through a cooling fan and cooling fins, but it cannot conveniently and stably splice and stack multiple converters. Therefore, multiple converters need to be placed in different positions, resulting in a large footprint and affecting the use and operation of staff, and the practicality is poor; and the existing converters cannot be conveniently and stably disassembled and installed during actual working, and thus cannot ensure the convenience of subsequent inspection and maintenance work, and cannot automatically protect the joints of the connecting cables.

Therefore, we have made improvements to this and proposed a multi-layer stacked converter structure. Summary of the Invention

At this time, the air storage frame 206 can suck the air inside the rubber suction cup 210 through the connecting pipe 208 and the fixing pipe 209, so that a negative pressure is formed inside the rubber suction cup 210. Under the joint action of each rubber suction cup 210, the overall structure of the converter can be automatically and stably adsorbed and fixed on the placement surface, thereby ensuring the stability and safety of the subsequent working state of the converter as a whole.

[0051] And during the assembly process of the converter body 3, during the downward movement of the converter body 3, the inclined surface of the second guide plate 610 can be driven to contact the top of the positioning rod 201. At this time, under the action of the downward movement of the converter body 3, the positioning rod 201 can push the second guide plate 610 to automatically move toward the fixed frame 601. Under the action of the movement of the second guide plate 610, the sliding rod 608 can be driven to contact the inclined surface of the first guide plate 607, and by pushing the first guide plate 607, the clamping plate 603 can be driven to move toward the cable 16; at this time, the clamping plates 603 on the upper and lower sides move toward the cable 16 at the same time, and combined with the various wire management grooves 604 on the clamping plates 603, each cable 16 can be automatically clamped and fixed and the wire management work can be convenient. , standardize the position of the cable 16, reduce the possibility of short circuit, and effectively avoid the problem that the cable 16 is easily loosened due to external influences during the operation of the converter body 3, which in turn leads to poor contact, output voltage fluctuations and other problems. In addition, during the movement of the second guide plate 610, the plug rod 614 can be pushed synchronously. At this time, the plug rod 614 can push the second rubber piston 613 to move into the air storage tank 611. At this time, under the joint action of the first air guide tube 615 and the second air guide tube 616, the inflation of each rubber airbag 605 can be automatically completed, realizing automatic sealing protection at the cable 16 joint, preventing dust and impurities in the outside air from entering the cable 16 joint, resulting in poor contact at the cable 16 joint.

[0052] Moreover, during the assembly process of the converter body 3, the converter body 3 can drive the first heat exchange tube 710 on the second heat exchange tube 711 to be inserted into the top of the connecting tube 708, and the sealing connection can be automatically completed in combination with the sealing ring 709. During the subsequent operation of the converter body 3, under the action of the refrigeration plate 702, the coolant in the insulation box 701 can be continuously cooled, and under the driving action of the drive motor 703, the first gear 704 on the output shaft can drive the second gears 705 on both sides to rotate stably, and then drive the screw rods 706 on both sides to rotate in the same direction on the corresponding conveying cylinder 707. Since the rotation directions of the screw rods 706 on both sides are the same and the directions of the spiral blades are opposite, the spiral feeding direction of the screw rod 706 on one side is upward, and the spiral feeding direction of the screw rod 706 on the other side is downward. Therefore, the continuous rotation of the screw rod 706 on one side In use, the coolant in the insulation box 701 can be automatically transported to the first heat exchange tube 710 on one side through the conveying cylinder 707 through the connecting pipe 708, and the first heat exchange tube 710 can transport the coolant to the second heat exchange tube 711. Then the coolant can be transported from the other end of the second heat exchange tube 711 to the first heat exchange tube 710 on the other side. At this time, the coolant can be stably refluxed to the insulation box 701 under the downward feeding action of the spiral rod 706 on the other side, completing the automatic circulation of the coolant, and realizing the circulation of the coolant in the first heat exchange tube 710 and the second heat exchange tube 711. By utilizing the heat exchange principle, the converter body 3 can be continuously and evenly cooled, which can help maintain the converter body 3 within a safe temperature range, avoid failure or damage caused by overheating, and ensure that the converter body 3 operates at optimal efficiency to reduce energy waste.

[0053] When high-power and long-distance power transmission work requires multiple converter structures to work together, the staff first operates on the assembled converter structure, and pulls the pull plate 12 on the upper side of the connecting plate 8 to move the card plate 13 out of the slot 15 on the splicing plate 14, and then the splicing plate 14 can be pulled upward. After pulling to the appropriate length, the pull plate 12 can be released. At this time, under the elastic action of the fifth spring 11, the pull plate 12 can drive the card plate 13 to automatically engage with the adjacent slot 15, completing the stretching and locking fixation of the splicing plate 14. Through the same operation, the splicing plates 14 on each connecting plate 8 are pulled upward to the same height, and then the staff can place another mounting plate 1 on top of the assembled converter structure, and insert the limiting slot 10 at the bottom of the upper connecting plate 8 into the splicing plate below. The top of the splicing plate 14 can be stably inserted into the limiting groove 10 by pulling the pull plate 12 on the lower side of the upper connecting plate 8, and then the pull plate 12 on the lower side can be released. At this time, under the elastic action of the fifth spring 11, the pull plate 12 can drive the card plate 13 to automatically snap into the card groove 15 at the top of the splicing plate 14, completing the snap-fitting and fixing of the splicing plate 14 and the other connecting plate 8, thereby completing the snap-fitting and fixing of the upper mounting plate 1, and then the staff can assemble the converter body 3 on the upper mounting plate 1; through the same operation, the multi-layer stacking of multiple converter overall structures can be conveniently completed. By stacking multiple converters together, the integration of the system is greatly improved, which makes the entire system more compact, can achieve higher space utilization, and improves the convenience of operation of the staff;

[0054] When the stacked converter bodies 3 need to be disassembled, it is only necessary to pull the pull plate 12 on the upper side of the connecting plate 8 again to move the clamping plate 13 out of the clamping slot 15 on the splicing plate 14, and the upper converter body 3 can be disassembled; when the converter body 3 needs to be disassembled for maintenance, it is only necessary to push the stopper 203 to move into the positioning rod 201. At this time, the stopper 203 is no longer blocked, and the converter body 3 can drive the fixing plate 4 to move upward and disengage from the positioning rod 201, thereby conveniently completing the disassembly of the converter body 3;

[0055] At this time, under the elastic action of the second spring 207, the push rod 204 and the first rubber piston 205 can be driven to move upward and reset, ensuring the stability of the subsequent repeated use state; similarly, after the second guide plate 610 moves away from the positioning rod 201, under the elastic action of the third spring 602, the clamping plate 603 can be driven to move upward to the inside of the fixed frame 601 to reset, and then the second guide plate 610 can be pushed to the side to reset through the first guide plate 607 and the sliding rod 608, ensuring the stability of subsequent repeated work; and under the movement action of the second guide plate 610, combined with the fourth spring 612, the second rubber piston 613 can be driven to move sideways and reset, at this time the clamping plate 603 automatically moves away from the cable 16, and the rubber airbag 605 automatically releases the inflation state, ensuring the convenience of subsequent connection and maintenance work of the cable 16.
