Description

Technical Field

[0001] This utility model relates to the technical field of soft starter mounting structure, specifically to a soft starter connection structure. Background Technology

[0002] A soft starter is an electrical control device primarily used for the smooth starting and stopping of electric motors. It reduces mechanical shock and grid current fluctuations during startup by gradually adjusting voltage or current (e.g., using thyristor voltage regulation or frequency conversion technology), thereby protecting the motor and load equipment and extending their service life. Commonly used in industrial applications requiring smooth start-stop operations, such as water pumps, fans, and conveyor belts, it also offers energy savings and reduces interference to the power grid.

[0003] In harsh working environments, soft starters need to be equipped with protective boxes or control cabinets. When the soft starter is connected inside the control cabinet, it is often directly connected to the inner wall of the cabinet with bolts. The gap between the soft starter and the inner wall of the cabinet is small, which is not conducive to heat dissipation. During the start-up process, the temperature of the thyristor will rise. If the heat dissipation is not good, the thyristor may be damaged due to high temperature, affecting the stability of the soft starter. Utility Model Content

[0004] The purpose of this utility model is to provide a soft starter connection structure to solve the problem that the existing technology of directly connecting the soft starter to the inner wall of the cabinet with bolts will lead to poor heat dissipation performance.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a soft starter connection structure, comprising:

[0026] The protection cabinet 1 and the soft starter body 11 are provided with a cabinet door rotatably connected to the outer surface of the protection cabinet 1.

[0027] Suspended mounting mechanism 2 is installed on the protection cabinet 1 and the soft starter body 11. The suspended mounting mechanism 2 is used to improve the natural heat dissipation effect of the soft starter body 11.

[0028] Auxiliary heat dissipation mechanism 3 is installed on the protective cabinet 1 and is used to provide protective heat dissipation for the soft starter body 11.

[0029] The suspended mounting mechanism 2 includes a raised frame 21, which is fixedly installed on the inner wall of the protective cabinet 1. A connecting block 22 is fixedly connected to the outer wall of the raised frame 21. A connecting piece 23 is movably sleeved on the outer wall of the connecting block 22. The connecting piece 23 is fixedly installed on the outer wall of the soft starter body 11. Through the cooperation of the protective cabinet 1 and the cabinet door, the soft starter body 11 can be stored and protected, ensuring the stability of the soft starter body 11 in a harsh environment. After the connecting piece 23 is sleeved on the outer wall of the connecting block 22, the soft starter body 11 can be positioned in the middle of the inner cavity of the protective cabinet 1 by the support of the raised frame 21, which improves the natural heat dissipation performance of the soft starter body 11, avoids the problem of poor heat dissipation due to small gaps, and ensures the stability of the soft starter body 11 during operation.

[0030] As one implementation method in this embodiment, such as Figure 4As shown, a rotating block 221 is rotatably connected to the inner wall of the connecting block 22, and an elastic element 222 is fixedly installed on the outer wall of the rotating block 221. A connecting post 223 is fixedly installed at the end of the elastic element 222 away from the rotating block 221. Through the design of the connecting block 22, the rotating block 221, the elastic element 222 and the connecting post 223, the user can pull the connecting post 223 in a direction away from the connecting block 22, which will stretch the elastic element 222. After releasing, the elastic force of the elastic element 222 can drive the connecting post 223 to reset, and the user can rotate and adjust the connecting post 223 as a whole.

[0031] As one implementation method in this embodiment, such as Figure 4 As shown, a limiting plate 224 is fixedly sleeved on the outer wall of the connecting column 223. A protrusion 225 is fixedly connected to the outer wall of the limiting plate 224. When disassembling and assembling the soft starter body 11, the user can pull the limiting plate 224 from the protrusion 225 and then rotate the limiting plate 224 to make the limiting plate 224 overlap with the connecting block 22 in the front-back direction. The soft starter body 11 can then be disassembled and assembled. After the soft starter body 11 is installed, the position of the limiting plate 224 is readjusted so that the limiting plate 224 and the connecting block 22 do not overlap in the front-back direction. This completes the limiting installation of the soft starter body 11, replacing the traditional bolt connection. No tools are needed, which improves the convenience of disassembling and maintaining the soft starter body 11.

[0032] As one implementation method in this embodiment, such as Figure 5 As shown, the auxiliary heat dissipation mechanism 3 includes a hollow plate 31, which is fixedly installed on the inner wall of the protective cabinet 1 near the bottom. A heat dissipation fan 313 is fixedly connected to the bottom of the hollow plate 31, and the top opening of the hollow plate 31 communicates with the inner cavity of the protective cabinet 1. Through the design of the air filter plate 312, the heat dissipation air entering the protective cabinet 1 can be filtered to ensure the stability of the soft starter body 11. The frame 311 is installed in the inner cavity of the hollow plate 31 with bolts. During maintenance, the user can disassemble and clean the air filter plate 312.

[0033] As one implementation method in this embodiment, such as Figure 5 As shown, a frame 311 is detachably connected to the inner wall of the hollow plate 31. An air filter plate 312 is fixedly installed on the inner wall of the frame 311. A round hole corresponding to the cooling fan 313 is opened at the bottom of the hollow plate 31. The cooling fan 313 is controlled to work, which can absorb cold air from the outside and deliver it to the inner cavity of the hollow plate 31. The cold air will then enter the inner cavity of the protection cabinet 1 to dissipate heat on the surface of the suspended soft starter body 11.

[0034] As one implementation method in this embodiment, such as Figure 6As shown, the auxiliary heat dissipation mechanism 3 also includes an exhaust pipe 32, which is fixedly connected to the top of the protective cabinet 1. A fixing block 321 is fixedly installed on the inner wall of the exhaust pipe 32, and an elastic rope 322 is fixedly connected to the outer wall of the fixing block 321. A plug 323 is fixedly connected to the end of the elastic rope 322 away from the fixing block 321. The plug 323 is movably inserted into the end of the exhaust pipe 32. An exhaust groove 324 is opened on the outer wall of the plug 323. When the cooling fan 313 is running, the air pressure inside the protective cabinet 1 will increase. The air pressure will push the plug 323 and then discharge gas from the exhaust groove 324. At this time, the elastic rope 322 will be stretched. After the cooling fan 313 stops working, the elastic rope 322 will drive the plug 323 to reset and seal the end of the exhaust pipe 32 to prevent dust and other impurities from flowing into the protective cabinet 1.

[0035] Working principle: During use, when disassembling and assembling the soft starter body 11, the user can pull the limiting plate 224 from the protrusion 225 and then rotate the limiting plate 224 to make it overlap with the connecting block 22 in the front-back direction. This allows for the disassembly and assembly of the soft starter body 11. After installation, the position of the limiting plate 224 is readjusted so that it does not overlap with the connecting block 22 in the front-back direction, thus completing the limiting installation of the soft starter body 11. At this time, supported by the protrusion bracket 21, the soft starter body 11 can be... Located in the middle of the inner cavity of the protection cabinet 1, it enhances the natural heat dissipation performance of the soft starter body 11 and controls the operation of the cooling fan 313. It can absorb cold air from the outside and deliver it to the inner cavity of the hollow plate 31. The cold air will then enter the inner cavity of the protection cabinet 1 to dissipate heat on the surface of the suspended soft starter body 11. When the cooling fan 313 is running, the air pressure inside the protection cabinet 1 will increase, pushing the plug 323 and then discharging the gas from the exhaust slot 324. After the cooling fan 313 stops working, the elastic rope 322 will drive the plug 323 to reset and seal the end of the exhaust pipe 32.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
