[0001] This utility model belongs to the field of frequency converter technology, and specifically relates to a low-power general-purpose frequency converter device. Background Technology

[0002] A low-power general-purpose frequency converter is a power electronic device used to control the speed and operating status of low-power motors. It first converts AC power to DC power through a rectifier circuit, and then converts the DC power back to AC power with adjustable frequency and voltage through an inverter circuit, supplying the motor with this AC power. By changing the frequency of the output AC power, the motor speed can be adjusted to meet different application requirements.

[0003] The utility model patent with publication number CN 216959637 U in the prior art proposes a low-power general-purpose frequency converter, which includes a frequency converter body and a base plate located below the frequency converter body. Side plates are fixedly connected to the left and right sides of the upper end face of the base plate, and shock-absorbing plates are fixedly connected to the upper end face of multiple shock-absorbing springs. The multiple shock-absorbing springs absorb and buffer the vibration force, reduce vibration, and thus avoid damage to the internal components of the frequency converter body.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As shown in Figures 1-5, this embodiment provides a low-power universal frequency converter device, including a device body 1, a base 2 inside the device body 1, a waterproof cover 4 above the base 2, a frequency converter body 8 inside the waterproof cover 4, and a water guide plate 5 connected above the waterproof cover 4. The base 2 has a first mounting groove 9 and a second mounting groove 10. A lead screw 11 is provided in the first mounting groove 9, a collar 14 is screwed onto the lead screw 11, and one end of the lead screw 11 is connected to a motor 12. The frequency converter body 8 is connected above the collar 14. The frequency converter body 8 has a placement groove 18 inside, and a controller 21, a plug hole 17 and a cooling fan 23 are provided inside the frequency converter body 8. A temperature sensor 19 is provided in the placement groove 18, and a support frame 24 is provided on the cooling fan 23.

[0029] Preferably, a waterproof platform 3 is installed below the base 2, and the waterproof platform 3 is fixedly connected to the base 2. By setting the waterproof platform 3, the base 2 can be waterproofed and protected, preventing the base 2 from contacting rainwater and affecting the subsequent use of the device, thus ensuring the safety of the device during use. The waterproof cover 4 has heat dissipation grooves 7, and multiple sets of heat dissipation grooves 7 are provided. By setting the heat dissipation grooves 7, the heat generated by the operation of the device can be dissipated, preventing heat accumulation and affecting the subsequent use of the device. The water guide plate 5 has water guide channels 6, and multiple sets of water guide channels 6 are long arc-shaped channels. By setting the water guide channels 6, rainwater can be guided and diverted to prevent rainwater from entering the device.

[0030] Preferably, a fixing seat 13 is fixedly installed below the motor 12. One end of the fixing seat 13 is welded and fixed to the outer wall of the base 2. By setting the fixing seat 13, the stability of the motor 12 is increased, ensuring the safety of the motor 12 during use. A guide rod 16 is set in the mounting groove 10, and a guide ring 15 is slidably sleeved on the guide rod 16. Two sets of guide rings 15 are symmetrically arranged. The guide rings 15 are fixedly connected to the inverter body 8. By setting the guide rod 16 and the guide rings 15, the direction of movement of the inverter body 8 can be guided, preventing the inverter body 8 from moving in the wrong direction. In case of positional deviation during operation, a protective cover 20 is installed inside the placement slot 18. The protective cover 20 is located in front of the temperature sensor 19 and is movably engaged with the placement slot 18. By setting the protective cover 20, the placement slot 18 can be protected from dust, ensuring the safety of the electronic components inside the placement slot 18. A dust cover 22 is installed inside the inverter body 8. The dust cover 22 is located behind the cooling fan 23. By setting the dust cover 22, the inverter body 8 can be protected from dust, reducing the possibility of dust entering the device and ensuring the safety of the device.

[0031] The working principle and operation process of this utility model are as follows: During use, the user can install the inverter body 8 inside the waterproof cover 4. In rainy weather, rainwater flows out of the device along the openings of the guide plate and water guide groove 6. When maintenance of the inverter body 8 is required, the motor 12 is controlled to run, driving the lead screw 11 to rotate. The lead screw 11 drives the collar 14 to move horizontally on the lead screw 11. As the collar 14 moves, it moves the inverter body 8. As the inverter body 8 moves, it causes the guide ring 15 to slide on the guide rod 16 until the inverter body 8 moves outside the waterproof cover 4, making it convenient for the user to perform maintenance. After maintenance, the inverter body 8 can be reset. The device can be moved horizontally according to usage needs, which facilitates installation and improves the flexibility of the device. The device can be inspected and maintained without disassembling the waterproof cover 4, which optimizes the waterproof effect and ensures the safety of the device during use. When the device generates heat during operation, if the heat reaches a certain temperature, the temperature sensor 19 transmits the temperature information to the controller 21. The controller 21 drives the cooling fan 23 to dissipate heat from the inverter body 8. The device can monitor the heat generated inside in real time, which facilitates heat dissipation and maintenance of the device and prevents the inverter from being damaged due to overheating.
