Description

Technical Field

[0001] This utility model belongs to the field of energy power supply equipment technology, and in particular relates to a convenient bidirectional converter. Background Technology

[0002] A bidirectional converter is an integrated device that combines power conversion, control, and heat dissipation systems. Its core function is to achieve bidirectional and efficient conversion between DC and AC power, and it is a key interface for energy application scenarios such as energy storage systems and microgrids.

[0003] Currently, these types of converters generally adopt a standardized enclosure structure, and the wiring port positions and outgoing angles of their external (DC and AC sides) cables are fixed at the factory. This connection method pursues structural compactness and integration; during installation, it is only necessary to connect the cables to the designated ports.

[0004] However, this fixed connection method has a clear technical drawback: when the converter's installation location does not match the cable trench or pipeline layout, it forces the cable to undergo unnatural forced bending at the port. This unreasonable bending causes the cable (especially large-section power cables) to bear excessive mechanical stress, which can easily lead to fatigue damage of the wire core, wear and even cracking of the external insulation layer under long-term action. This not only significantly shortens the cable's lifespan but also causes serious safety hazards such as overheating at the connection point and insulation failure, threatening the reliable operation of the entire system. Utility Model Content

The rotary connection device is fixedly installed in the first arc-shaped recessed surface. A rotating end extends from the side of the rotary connection device, rotating around its central axis. This rotating end is connected to the second arc-shaped recessed surface. The rotation of the rotating end of the rotary connection device causes the wiring device to rotate around the rotary connection device, thereby adjusting the orientation of the terminal block on the back of the wiring device and adjusting the insertion angle of the external wiring. This prevents damage to the wire ends due to excessive bending angles. In use, the angle of the wiring device is adjusted by rotating the rotating end of the rotary connection device according to actual wiring requirements. This structural design effectively prevents damage to the connecting wires. Attached Figure Description

[0028] In one embodiment of this utility model, such as Figures 1-2 As shown, a convenient bidirectional converter is provided, which is assembled from a main body 10, a wiring device 20, and a rotary connection device 30. A first arc-shaped recessed surface 11 is formed on the side of the outer shell of the main body 10, and a first through hole 12 is formed on the first arc-shaped recessed surface 11. The first through hole 12 is used for the equipment lines inside the main body 10 to pass through. A wiring hole 315 is formed on the mounting post 31 of the rotary connection device 30. After the mounting post 31 is fixedly installed on the first arc-shaped recessed surface 11, the wiring hole 315 is connected to the first through hole 12. An adjustment clearance hole is also provided on the side of the mounting post 31. The adjustment clearance hole is elongated and is rotatably mounted on the rotating rod 33 within the mounting post 31. The rotating rod 33 is vertically positioned with one end extending upwards through the top plane of the mounting post 31. A positioning gear 331 and an adjusting turntable 32 are fixedly mounted on the extended end of the rotating rod 33. The positioning gear 331 is located above the mounting post 31 and is positioned close to the top plane of the mounting post 31. The adjusting turntable 32 is located at the top of the rotating rod 33. The rotating rod 33 is rotated by rotating the adjusting turntable 32. Figure 3 As shown, a positioning hole 313 is provided on the top plane of the mounting post 31, and a pin 314 is inserted into the positioning hole 313. The positioning hole 313 is located in the gap coverage area between the teeth of the positioning gear 331. When the positioning gear 331 rotates a certain angle, the pin 314 is inserted and locked between two teeth, restricting the rotation of the positioning gear 331, thereby restricting the rotation of the rotating rod 33. A connecting rod 34 is fixedly installed on the side of the rotating rod 33. The connecting rod 34 is set perpendicular to the rotating rod 33, and the other end of the connecting rod 34 passes through the adjustment clearance hole. The rotation of the rotating rod 33 causes the other end of the connecting rod 34 to swing in the area of ​​the adjustment clearance hole. The other end of the connecting rod 34 is connected to the second arc-shaped concave surface 21 provided on the side of the wiring device 20, and a wire groove 341 is provided on the connecting rod 34. Figure 5As shown, one end of the buried wire groove 341 extends through the connecting rod 34 and connects to the end side of the second arc-shaped concave surface 21. A second wire hole 22 is provided on the second arc-shaped concave surface 21, and the second wire hole 22 is partially connected to the buried wire groove 341.

[0029] like Figure 2 and Figure 4 As shown, four movable wheels 23 are provided on the second arc-shaped concave surface 21 of the wiring device 20, and four mounting grooves are provided on the second arc-shaped concave surface 21. The four mounting grooves are arranged in a matrix. Two mounting grooves are located near the top edge of the second arc-shaped concave surface 21, and two mounting grooves are located near the bottom edge of the second arc-shaped concave surface 21. Movable wheels 23 are rotatably installed in each of the four mounting grooves, and the rotation axis of each movable wheel 23 is vertically arranged. The upper and lower sets of movable wheels 23 are slidably connected to the sliding grooves 311 provided on the side of the mounting column 31. The two sliding grooves 311 are located near the top and bottom of the mounting column 31, respectively. Each set of movable wheels 23 slides along the sliding grooves 311 to reduce the friction between the second arc-shaped concave surface 21 and the outer side of the mounting column 31.

[0030] like Figure 2 As shown, a rotating base plate 312 is fixedly installed at the bottom of the mounting column 31. An arc-shaped groove 3121 is provided on the upper surface of the rotating base plate 312. A pulley 24 provided at the bottom of the wiring device 20 moves back and forth along the arc-shaped groove 3121.

[0031] In use, adjust the rotating disc 32 to rotate the rotating rod 33 according to the angle of the connector, which in turn drives the connecting rod 34 to rotate, causing the connector 20 to rotate around the mounting post 31. When the ideal angle is reached, the pin 314 is inserted. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
