[0002] A rotating rectifier is a device used in power systems. Its main function is to convert alternating current into direct current, so that the power system can provide a stable power supply for DC devices or circuits. Rotating rectifiers are usually installed on a solid foundation or platform by bolts and screws to ensure that the equipment is stable during operation and does not produce excessive vibration or displacement. However, when the screws are fixed, they usually need to be equipped with screws themselves, washers, and sleeve nuts. The parts are relatively small. For rotating rectifiers that need to be disassembled and assembled many times, it is easy for the fixed parts to be lost. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] To solve the problem that the fixing parts of the existing rotating rectifier module are easily lost when it is fixed and assembled with the foundation or platform, please refer to Figure 1-Figure 4 The utility model provides a fixing structure of a rotating rectifier module, in which a rotating rectifier 2 is plugged into a chassis assembly 1. At this time, the rotating rectifier 2 cannot swing left and right. In addition, a clamping assembly 3 installed on the chassis assembly 1 is used to fix the rotating rectifier 2 along the side in a plug-in manner to prevent the rotating rectifier 2 from moving upward. The combination of the clamping assembly 3 and the chassis assembly 1 can realize a fixed combination of the rotating rectifier 2.

[0022] like Figure 1 and Figure 4 As shown, the clamping assembly 3 includes a long threaded rod 301 threadedly inserted into the side of the chassis assembly 1, a vertical plate 302 is arranged on the outer side of the chassis assembly 1, an inner groove 3021 is opened on the side of the vertical plate 302 close to the chassis assembly 1, an engaging plate 3011 rotatably inserted into the inner groove 3021 is installed at one end of the long threaded rod 301, and a pressing block 3022 pressed on the rotating rectifier 2 is installed on one side of the vertical plate 302. After inserting the rotating rectifier 2 and the chassis assembly 1, the long threaded rod 301 is rotated in the set direction on the inner side of the chassis assembly 1, driving the interlocking plate 3011 to rotate in the inner groove 3021 on the upright plate 302, and at the same time, the long threaded rod 301 moves and extends toward the center of the chassis assembly 1, and the upright plate 302 and the pressing block 3022 follow the movement, and the limiting rod 303 installed on one side of the upright plate 302 gradually extends into the interior of the chassis assembly 1, ensuring that the upright plate 302 can always remain in a vertical state when the long threaded rod 301 is rotated. As the long threaded rod 301 continues to rotate, the pressing block 3022 is firmly pressed on the rotating rectifier 2, thereby fixing the rotating rectifier 2 vertically plugged into the chassis assembly 1.

[0023] like Figure 2 and Figure 3As shown, the chassis assembly 1 includes an annular chassis 101 located below the rotating rectifier 2, and two supporting ring bodies 102 arranged in concentric rings and connected to the long threaded rods 301 are installed on the top of the annular chassis 101. The rotating rectifier 2 includes a supporting base plate 201 placed on the two supporting ring bodies 102 and a rectifier main body module 202 installed on the top surface of the supporting base plate 201. A through groove 2011 is opened on the supporting base plate 201, and a positioning column 1021 passing through the through groove 2011 is installed on the top of the supporting ring body 102. The rotating rectifier 2 is lifted upward by the supporting ring body 102, so that a certain space for air circulation and wiring is generated between the bottom of the rotating rectifier 2 and the annular chassis 101. In actual application, the through slot 2011 on the supporting bottom plate 201 is aligned with the positioning column 1021 on the supporting ring body 102, and then the rotating rectifier 2 is driven to move downward as a whole, and the plug-in combination between the supporting bottom plate 201 and the supporting ring body 102 is performed, and the upper surface of the supporting bottom plate 201 is pressed by the pressing block 3022 in the clamping assembly 3, so as to achieve the purpose of fixing the rotating rectifier 2. Since the bottom of the pressing block 3022 is tilted downward from one side to the side close to the upright plate 302, the supporting bottom plates 201 of different thicknesses in the rotating rectifier 2 can be pressed.

[0024] like Figure 2 As shown, a plurality of holes 1022 are provided on the support ring body 102 to facilitate the circulation of external air between the two support ring bodies 102, thereby avoiding the accumulation of heat at the bottom of the rotating rectifier 2. A central axis ring body 103 is installed on the inner wall of the annular chassis 101, and the outer surface of the central axis ring body 103 is in contact with the inner wall of the recess of the supporting bottom plate 201. The central axis ring body 103 is in an integrated form with the annular chassis 101, and is in contact with the combined rotating rectifier 2. A tight-fitting cylinder 1031 is installed inside the central axis ring body 103, and the inside of the tight-fitting cylinder 1031 is in contact with the outer shape of the screw, thereby facilitating the fixing of the rotating rectifier 2 with the chassis assembly 1 on the stator of the motor.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
