DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] Embodiment 1

[0027] A water-cooling plate of an explosion-proof frequency converter, comprising two water-cooling plates 1, and a water-cooling pipe 2 arranged between the two water-cooling plates 1, a connecting seat 3 is fixedly arranged on the side of the water-cooling plate 1, a separation mechanism is arranged between the two connecting seats 3 of different water-cooling plates 1, and a driving mechanism is arranged on the side of the water-cooling plate 1, and the driving mechanism cooperates with the separation mechanism;

[0028] The separation mechanism includes an inclined groove 4, a receiving groove 5, a traction seat 6 and a guide rod 7. The inclined groove 4 and the receiving groove 5 are both arranged on the surface of the connecting seat 3, and the inclined groove 4 and the receiving groove 5 are connected to each other. The guide rod 7 is fixedly arranged on the side of the traction seat 6, and the traction seat 6 is attached to the surface of the water-cooled plate 1. One end of the guide rod 7 enters the inclined groove 4 from the top of the receiving groove 5, and the guide rod 7 can slide in the receiving groove 5 and the inclined groove 4. One end of the traction seat 6 cooperates with the driving mechanism. The driving mechanism includes a base 8, a sleeve 9, a handle 10, a threaded rod 20 and a connecting arm 11. The base 8 is in contact with the side of the water-cooled plate 1 through a limiter. The bottom end of the threaded rod 20 is rotatably arranged on the base 8, the handle 10 is fixed to the top of the threaded rod 20, the sleeve 9 is threadedly connected to the surface of the threaded rod 20, and the side of the sleeve 9 and the surface of the traction seat 6 are fixedly provided with a rotating seat 19, and the two ends of the connecting arm 11 are rotatably connected between the two rotating seats 19.

[0029] See also Figure 1 , 2 3. After turning the handle 10, the handle 10 drives the threaded rod 20 to rotate. Since the base 8 is in contact with the side of the water-cooling plate 1 through the limiter, the threaded rod 20 can rotate on the surface of the base 8 at this time. When the threaded rod 20 rotates, it can drive the sleeve 9 to move up on its surface. When the sleeve 9 rises, the sleeve 9 can drive one end of the connecting arm 11 to rise through the connecting seat 3, and the overall length of the connecting arm 11 remains unchanged. Therefore, at this time, the other end of the connecting arm 11 can pull the traction seat 6 through the connecting seat 3 to move horizontally between the two connecting seats 3. At this time The traction seat 6 can drive the guide rod 7 to move synchronously. Since the length of the guide rod 7 is also fixed, but the distance between the two inclined grooves 4 gradually decreases along the direction close to the threaded rod 20, the guide rod 7 can push the inclined groove 4 during the movement, so that the two connecting seats 3 move away from each other. At this time, the thrust exerted on the connecting seat 3 will be transmitted to the water-cooled plate 1, thereby realizing the separation between the two water-cooled plates 1. Since the driving mechanisms on both sides of the water-cooled plate 1 can be operated synchronously by two workers, the separation force exerted on both ends of the water-cooled plate 1 is relatively uniform.

[0030] The limiting member includes a limiting block 12 and a positioning seat 13 . The positioning seat 13 is fixedly disposed on the side of the base 8 . The limiting block 12 is fixedly disposed on the side of the water-cooling plate 1 . The positioning seat 13 is engaged between the two limiting blocks 12 .

[0031] See also Figure 3 When the positioning seat 13 is stuck between the two limit blocks 12, the angle of the base 8 is limited, and when the threaded rod 20 rotates, the base 8 will not be driven to rotate synchronously, thereby facilitating the driving of the sleeve 9 through the threaded rod 20.

[0032] A ball 16 is provided at one end of the guide rod 7 , and one end of the ball 16 just contacts the inner wall of the receiving groove 5 , and the side surface of the traction seat 6 fits the side surface of the connecting seat 3 .

[0033] See also Figure 4 When the guide rod 7 moves, it can drive the ball 16 to move synchronously. At this time, the ball 16 is always tangent to the receiving groove 5 and the inclined groove 4, and the spherical surface of the ball 16 can better transition from the receiving groove 5 to the inclined groove 4, so that the traction seat 6 will not get stuck during the movement.

[0034] Embodiment 2

[0035] The above embodiment drives the two connecting seats 3 away from each other by the laterally moving guide rod 7, thereby realizing the separation of the two water-cooling plates 1, but the connecting arm 11 cannot drive the traction seat 6 to avoid angular deflection during translation, which will cause the guide rod 7 to push the connecting seat 3 through the inclined groove 4. The distance pushed by each guide rod 7 is different. Therefore, in this embodiment, a guide mechanism is arranged between the traction seat 6 and the connecting seat 3, and the guide mechanism includes a guide block 14 and a slide groove 15. The guide block 14 is fixedly arranged on the side of the traction seat 6, and the slide groove 15 is horizontally arranged on the surface of the connecting seat 3, and the guide block 14 is slidably arranged in the slide groove 15.

[0036] See also Figure 4 After the guide rod 7 is located in the accommodating groove 5, the guide block 14 is located at one end of the slide groove 15, and the slide groove 15 is parallel to the side ridges of the connecting seat 3 as a whole. When the traction seat 6 moves, the traction seat 6 can drive the guide block 14 to move synchronously inside the slide groove 15. Through the cooperation of the guide block 14 and the slide groove 15, the traction seat 6 can only move horizontally on the side of the water-cooled plate 1, and cannot deflect at an angle. Therefore, when the guide rod 7 pushes the connecting seat 3 through the inclined groove 4, the force on both ends of the water-cooled plate 1 is more evenly applied.

[0037] A first through groove 17 and a second through groove 18 are provided on the surface of the connecting seat 3. The first through groove 17 connects the receiving groove 5 with the outside from the top, and the second through groove 18 connects the sliding groove 15 with the outside from the top.

[0038] See also Figure 5, the guide rod 7 can be moved from the accommodating groove 5 to the outside through the first through groove 17, and the guide block 14 can be moved from the slide groove 15 to the outside through the second through groove 18, which enables the traction seat 6 to be directly separated from the water-cooled plate 1 from the side of the connecting seat 3, and after the base 8 is removed from the side of the water-cooled plate 1, the traction seat 6, the connecting arm 11, the sleeve 9, the threaded rod 20 and the sleeve 9 can be removed from the side of the water-cooled plate 1 as a whole, so as to facilitate the transportation of the water-cooled plate 1, and the traction seat 6, the connecting arm 11, the sleeve 9, the threaded rod 20 and the sleeve 9 as a whole can form a tool specifically used for disassembling the water-cooled plate 1 in this embodiment, and when the water-cooled plate 1 is installed inside the explosion-proof inverter, the overall volume is reduced, thereby reducing the occupied space.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
