Description

Technical Field

[0001] The utility model belongs to the field of the main body of a rectifier cabinet, and particularly relates to a rectifier cabinet structure with a dust-proof net that can be conveniently disassembled and assembled. Background Art

[0002] A rectifier cabinet is a device that converts the relatively low-voltage alternating current output by an AC step-down device into direct current, and is commonly used in fields such as DC motor speed regulation, excitation regulation of generators, electrolysis, and electroplating. Since a large amount of heat is generated during the operation of the rectifier cabinet, it is necessary to dissipate heat from the rectifier cabinet during use.

[0003] Patent [CN218183806U] discloses a heat dissipation structure for a rectifier cabinet. By setting a heat dissipation mechanism, the inside of the rectifier cabinet main body is overall dissipated, and the heat dissipation effect is increased. Then, by setting a dust-proof mechanism, the dust entering the rectifier cabinet is reduced, and the electrical components are prevented from being damaged by dust. However, the following defects still exist in the actual application process of this patent:

[0004] In the above patent, the air inlet is blocked by a dust-proof net during use, and there are certain limitations in the actual use process. Since various impurities are easily attached to the dust-proof net during use, and these impurities are more likely to block the dust-proof net, affecting the ventilation and heat dissipation effect of the rectifier cabinet main body. In the prior art, the dust-proof net is installed outside the rectifier cabinet main body by screwing multiple groups of bolts. When it is necessary to disassemble the dust-proof net from the rectifier cabinet for cleaning and replacement, it takes a lot of time, and during the operation, tools are also required to assist in the disassembly, which is not convenient to use. Therefore, it is urgent to propose a rectifier cabinet structure with a dust-proof net that can be conveniently disassembled and assembled to solve the above problems. Summary of the Utility Model

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

It can be seen from the figure that the structure of the rectifier cabinet with a dust-proof net that can be conveniently disassembled and assembled according to the present utility model includes a rectifier cabinet main body 1 and a dust-proof net 2. An air inlet 101 is provided on the outer wall of the rectifier cabinet main body 1, and the dust-proof net 2 covers the outside of the air inlet 101. A frame 201 is fixedly provided on the outer wall of the dust-proof net 2, and a positioning port 202 is provided on the outer wall of the frame 201. A connection block 3 is fixedly installed on the outer wall of the rectifier cabinet main body 1. A connection groove 301 is provided in the inner wall of the connection block 3. A positioning block 303 is movably clamped in the inner cavity of the connection groove 301, and the outer wall of the positioning block 303 passes through the connection block 3 and is clamped in the corresponding positioning port 202. The above clamping device is provided with two groups and is symmetrically distributed. By adjusting the positioning block 303, the positioning block 303 is separated from the positioning port 202, which is convenient for disassembling the dust-proof net 2 from the rectifier cabinet main body 1, facilitating its replacement and cleaning in the later stage;

[0026] As Figure 4The figure shows a schematic structural diagram of a connection block of a rectifier cabinet with a dust-proof net of the present utility model that can be conveniently disassembled and assembled. An extrusion spring 302 is fixedly arranged inside the connection groove 301. One end of the extrusion spring 302 is fixed at the bottom of the connection groove 301, and the other end of the extrusion spring 302 is fixedly arranged on the outer wall of the positioning block 303. The positioning block 303 is pushed by the driving force of the extrusion spring 302 to move outward, and the position state of being stuck in the corresponding positioning port 202 is maintained without adjustment, improving the stability of the installation position of the dust-proof net 2. A moving rod 304 is fixedly arranged on the outer wall of the positioning block 303, and a groove is formed at the bottom of the connection block 3. The bottom of the moving rod 304 extends downward through the groove formed at the bottom of the connection block 3, which is used to extend the acting point of the positioning block 303, so that the positioning block 303 can be driven to move outward by adjusting the moving rod 304.

[0027] As Figure 5 The figure shows a schematic structural diagram of an adjusting block of the present utility model. The rectifier cabinet structure with a dust-proof net of the present utility model that can be conveniently disassembled and assembled includes an adjusting block 305. A groove is formed on the outer wall of the adjusting block 305, and the moving rod 304 is rotatably connected to the groove formed on the outer wall of the adjusting block 305 through a pin shaft. After the positioning block 303 is disengaged from the positioning port 202 and retracted into the connection groove 301, the user rotates the adjusting block 305 to make the side of the adjusting block 305 abut against the outer wall of the connection block 3. At this time, the positioning block 303 is fixed at this position, liberating the user's hands and facilitating the user to adjust and operate other structures. A pulling opening 306 is formed on the outer wall of the adjusting block 305. The pulling opening is semi-cylindrical, and the semi-cylindrical plane is on the outer wall of the adjusting block, which is convenient for the user to contact and take for adjustment.

[0028] A support rod 401 is fixedly arranged at the top of the rectifier cabinet main body 1, and a baffle 4 is fixedly arranged at the top of the support rod 401. The baffle 4 is in a slope shape, and the side surface of the baffle is trapezoidal and triangular, and the bottom heights of each side surface are equal, which plays a protective role for the top of the rectifier cabinet main body 1 and the air duct, preventing high-altitude falling objects from damaging the top of the rectifier cabinet main body 1 and the air duct, and improving safety.

[0029] The working principle of the present utility model is as follows:

[0030] Installation process of the dust-proof net: The dust-proof net 2 is set at the corresponding position of the rectifier cabinet main body 1. At this time, the positioning port 202 is aligned with the positioning block 303. The positioning block 303 is moved so that the positioning block 303 is inserted and stuck in the corresponding positioning port 202. Similarly, the positioning block 303 on the other side is stuck in the positioning port 202 on the other side, and the dust-proof net 2 is installed and restricted on the rectifier cabinet main body 1.

[0031] Dust-proof net disassembly process: Adjust the moving rod 304 to drive the positioning block 303 to move outward, move the positioning block 303 in another direction, so that the positioning block 303 is received into the connecting groove 301, rotate the adjusting block 305, make the side of the adjusting block 305 tightly abut against the outer wall of the moving rod 304, fix the positioning block 303 in this position, liberate the user's hands, and facilitate the user to adjust and operate other structures.
