Motor drive load simulation test power supply device with dynamic impedance simulation

Abstract

The application discloses a motor transmission load simulation test power supply device with dynamic impedance simulation, which comprises a detection body, a damping assembly and a heat dissipation assembly. A top piece of the damping assembly is fixedly connected in a groove hole formed in the bottom of the detection body. The bottom of the top piece is fixedly connected with a first spring. The other end of the first spring is fixedly connected with a bottom piece. The bottom of the bottom piece is uniformly provided with a second spring. A detection groove is formed in one side of the detection body. A module shell of the heat dissipation assembly is embedded and mounted in a groove hole formed in the top of the detection groove. A sliding block is slidably connected in a sliding groove of the module shell. The damping assembly effectively reduces noise, and simultaneously avoids the problem that a motor is not fixed firmly during a motor power supply test process. During the overload operation of the motor, the heat dissipation assembly accelerates the air circulation in the detection groove, so that the heat generated during the motor power supply test is discharged through the set ventilation plate, and the accuracy of the motor power supply test is avoided from being affected by high temperature.

Description

Technical Field

[0001] This invention relates to the field of motor testing technology, and in particular to a power supply device for simulating motor drive load testing with dynamic impedance simulation. Background Technology

[0002] Coal mine motor power supply testing equipment is used to detect the operating status of motors in coal mines. It plays an important role in ensuring coal mine production safety and improving production efficiency. The equipment is mainly used to detect various operating parameters of motors in coal mines, such as voltage, current, power, speed, and temperature, as well as key indicators such as insulation resistance and DC resistance. By monitoring these parameters in real time, abnormal motor conditions can be detected promptly, motor failures can be prevented, and the smooth operation of coal mine production can be ensured. Existing motor power supply testing mechanisms basically meet user needs, but some shortcomings still exist. Existing testing mechanisms generate significant noise during motor operation, affecting the working environment. Vibration can also cause the motor to loosen, affecting the test results. Furthermore, the heat generated during motor overload operation cannot be dissipated in time, easily leading to motor overheating and affecting the accuracy of the power supply test. Therefore, it is necessary to design a motor drive load simulation test power supply device with dynamic impedance simulation. Summary of the Invention

[0003] The purpose of this invention is to provide a power supply device for simulating motor drive load testing with dynamic impedance simulation, in order to solve the defects of existing coal mine motor power supply testing mechanisms, such as high noise during the testing process, large vibration that may cause the motor to become loose and affect the test results, and untimely heat dissipation that affects the accuracy of motor power supply testing.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a power supply device for simulating motor drive load with dynamic impedance simulation, comprising a detection body, a shock absorption component, and a heat dissipation component. A top component of the shock absorption component is fixedly connected to a slot at the bottom of the detection body. A first spring is fixedly connected to the bottom of the top component, and the other end of the first spring is fixedly connected to a bottom component. Second springs are evenly distributed at the bottom of the bottom component. A detection groove is provided on one side of the detection body. A module housing of the heat dissipation component is embedded in a slot at the top of the detection groove. A slider is slidably connected in a groove in the module housing. A motor is embedded in a slot in the slider, and a fan blade is fixedly connected to the output end of the motor.

[0005] As a further technical solution of the present invention, the shock absorption assembly consists of a top part, a first spring, a bottom part, a second spring, a first limiting structure, and a second limiting structure. The first limiting structure is fixedly connected to the top part, the first limiting structure is sleeved on the second limiting structure, and the second limiting structure is fixedly connected to the bottom part.

[0006] As a further technical solution of the present invention, one end of the second spring is fixedly connected to the support block, and a support foot is fixedly connected to the support block.

[0007] As a further technical solution of the present invention, the heat dissipation component consists of a module housing, a slider, a motor, a fan blade, a lead screw, a ball nut, a heat dissipation motor, and a motor housing. A ball nut is embedded in the slot of the slider, and the ball nut is connected to the lead screw. The lead screw and the slider are connected to each other through the ball nut.

[0008] As a further technical solution of the present invention, the lead screw is rotatably connected in a slot on one side of the module housing, and one end of the lead screw is fixedly connected to the output end of the heat dissipation motor, and the heat dissipation motor is fixedly connected to the motor housing.

[0009] As a further technical solution of the present invention, a testing platform is fixedly connected to the bottom of the inner side of the testing groove, and a ventilation plate is connected to one side of the testing groove.

[0010] As a further technical solution of the present invention, a barrier door is connected to the opening of the detection groove. The barrier door is rotatably connected to a rotating shaft, and the rotating shaft is fixedly connected to the detection body. A display screen is fixedly connected to one side of the detection body, and an operation knob is provided on one side of the detection body.

[0011] This invention provides a motor drive load simulation test power supply device with dynamic impedance simulation. Its advantages are as follows: By fixing the motor to be tested on a test platform, the vibration generated by the motor during the test causes the test body to vibrate. This vibration is transmitted to the top component and the first spring in the shock absorption assembly, and then further transmitted to the second spring through the bottom component. The elastic force of the first and second springs effectively reduces the vibration. The vibration is then transmitted to the ground through the support block and support feet, effectively reducing noise while avoiding the problem of the motor not being securely fixed during the power supply test. During motor overload operation, the cooling motor is activated, which drives the lead screw to rotate. The lead screw rotation drives the ball nut to move, which in turn drives the slider to slide in the groove opened in the module housing. Then, the motor starts, driving the fan blades to rotate, accelerating the airflow in the test groove, allowing the heat generated by the motor power supply test to be discharged through the ventilation plate, avoiding the impact of high temperature on the accuracy of the motor power supply test.
