Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, and particularly to an energy-saving control device for a three-phase asynchronous motor. Background Technique

[0002] The energy-saving control devices for three-phase asynchronous motors are mainly applicable to industrial occasions that require efficient and energy-saving operation. These devices optimize the operating state of the motors by intelligently adjusting parameters such as the voltage, current, or frequency of the motors, thereby reducing unnecessary energy consumption and improving the motor efficiency. They are widely used in automated control systems, manufacturing production lines, construction machinery, transportation, and other fields. Especially in the occasions where the motor load fluctuates greatly, frequent starting and stopping are required, or long-term continuous operation is carried out, they can significantly improve the production efficiency and energy utilization rate, and achieve the goal of energy conservation and consumption reduction.

[0003] However, the existing technologies still have the following problems:

[0004] First of all, currently, a key technical problem often faced by three-phase asynchronous motors during operation is the overheating phenomenon. This is mainly because the heat generated inside the motor cannot be dissipated in a timely and effective manner, resulting in an increase in the motor temperature, which in turn affects its operating efficiency and stability, and even shortens the motor life. Traditional heat dissipation methods often have problems such as low heat dissipation efficiency, limited heat exchange area, and uneven heat distribution, and it is difficult to meet the strict requirements for heat dissipation of high-performance motors.

[0005] In view of the above problems, the inventor proposes an energy-saving control device for a three-phase asynchronous motor to solve the above problems. Content of the Utility Model

[0006] In order to solve the problems of low heat dissipation efficiency, limited heat exchange area, and uneven heat distribution; the purpose of the utility model is to provide an energy-saving control device for a three-phase asynchronous motor.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme: An energy-saving control device for a three-phase asynchronous motor, including a chassis, a heat dissipation mechanism is provided at the upper end of the chassis for heat dissipation and energy conservation of the motor equipment, a biting mechanism is provided on one side of the heat dissipation mechanism for reducing the loss of transmission power, the heat dissipation mechanism includes a water-cooled housing, a liquid inlet and a liquid outlet are opened at the upper end of the water-cooled housing, a plurality of heat dissipation fins are fixedly arranged on the inner surface of the water-cooled housing, a plurality of heat conduction rods are fixedly arranged together on one side of the plurality of heat dissipation fins, a motor equipment is jointly arranged on the inner surface of the plurality of heat dissipation fins, and a plurality of slide rails are fixedly arranged on the outer surface of the motor equipment.

[0008] Compared with the existing technologies, the beneficial effects of the utility model are as follows:

[0009] 1. The utility model realizes efficient heat conduction and dissipation through a heat dissipation mechanism. The water-cooled outer shell design allows the coolant to circulate, effectively absorbing and taking away the heat generated by the motor equipment. The heat dissipation fins increase the heat exchange area, and the heat is evenly distributed throughout the heat dissipation mechanism through heat conduction rods, improving the heat dissipation efficiency, significantly reducing the temperature during the operation of the motor, and enhancing the overall energy-saving performance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0016] Embodiment: As Figures 1 - 3As shown in the figure, the utility model provides an energy-saving control device for a three-phase asynchronous motor. The chassis 1 serves as a stable foundation for the entire device, and the heat dissipation mechanism 2 is carried on its upper end. The core of the heat dissipation mechanism 2 is the water-cooled shell 20. The inlet 21 and outlet 22 are ingeniously designed at the top of the shell to facilitate the circulation of the coolant. On the inner surface of the water-cooled shell 20, a plurality of heat dissipation fins 23 are evenly distributed. These fins not only increase the heat exchange area but also quickly conduct the heat generated by the motor equipment 25 to the entire heat dissipation mechanism 2 through the heat conduction rods 24 fixed together on one side. The motor equipment 25 is ingeniously placed on the inner surface of the heat dissipation fins 23, and a plurality of slide rails 27 are fixed on its outer surface. These slide rails 27 not only facilitate the installation of the motor equipment 25 but also play a role in subsequent maintenance or adjustment. The engaging mechanism 3 is arranged adjacent to one side of the heat dissipation mechanism 2.

[0017] By opening a chute 29 on the heat dissipation fin 23 and slidingly fitting it with the slide rail 27 on the outer surface of the motor equipment 25, the flexible installation and disassembly of the heat dissipation fin 23 and the motor equipment 25 are realized. The cooperation of the limit block 28 slidably arranged on the slide rail 27 and the limit hole 26 effectively prevents the accidental movement or loosening of the heat dissipation fin 23 during the operation of the motor. The heat dissipation fins 23 are evenly distributed on the inner surface of the water-cooled shell 20, ensuring the uniformity of heat distribution.

[0018] The engaging mechanism 3 mainly consists of a plurality of engaging shafts 30. One end of these engaging shafts 30 is commonly connected to the engaging tooth shaft 33, forming the core of the transmission of the biting force. The outer surface of the engaging tooth shaft 33 is densely covered with teeth 32, which are used to cooperate with the engaging groove 39 at one end of the engaging shaft 30 to achieve precise engaging connection. At the same time, each end of the engaging shaft 30 is designed with an engaging opening 35 and an extrusion groove 36, which are respectively used for docking with other engaging shafts 30 and structures, and through the cooperation of the extrusion bolt 37 and the extrusion thread groove 34, a firm connection is achieved, ensuring the stability of the engaging mechanism 3 during operation. This layout design enables the engaging mechanism 3 to flexibly adapt to different connection requirements and achieve efficient and reliable engaging connection.

[0019] The engaging groove 39 opened on the engaging shaft 30 cooperates with the teeth 32 on the outer surface of the engaging tooth shaft 33 to achieve a tight engaging connection between the plurality of engaging shafts 30. The teeth 32 are annularly distributed on the outer surface of the engaging tooth shaft 33, which not only enhances the connection strength between the engaging tooth shaft 33 and the engaging shaft 30 but also makes the engaging process smoother. The cooperation of the extrusion thread groove 34 opened on the outer surface of the engaging shaft 30 and the extrusion bolt 37 provides a simple and effective fastening method, ensuring the tight connection between the engaging shafts 30.

[0020] Working principle: Through the heat dissipation mechanism 2, the coolant enters the water-cooled housing 20 from the liquid inlet 21, and when flowing through the heat dissipation fins 23, it absorbs the heat generated by the fin surface and the motor device 25 conducted through the heat conduction rod 24. Then, the heated coolant is discharged from the liquid outlet 22, completing a heat dissipation cycle. The heat dissipation fins 23 not only increase the heat exchange area, but also promote air flow through their structure, further improving the heat dissipation efficiency. During the whole process, the heat conduction rod 24 ensures that the heat is evenly and efficiently transferred from the motor device 25 to the heat dissipation fins 23, thereby achieving efficient cooling of the motor device 25;

[0021] Through the bite mechanism 3, one end of multiple bite shafts 30 bite each other through the bite gear shaft 33 and the teeth 32 on its surface to form a preliminary connecting force. Subsequently, the bite opening 35 at one end of the bite shaft 30 is docked with the corresponding part of the adjacent shaft or fixed structure, and the extrusion bolt 37 is screwed into the extrusion groove 36 and the extrusion screw groove 34 on the outer surface of the bite shaft 30 to generate a strong fastening force to ensure the stability of the bite connection. The coordinated use of the bite groove 39 and the teeth 32 further enhances the accuracy and reliability of the bite. The entire bite process is simple and efficient, can adapt to different connection requirements, and ensure the stability and safety of the device during operation.

[0022] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
