Description

Technical Field

[0001] The present invention relates to the technical field of variable frequency motors, in particular to a variable frequency motor with energy-saving effect. Background Art

[0002] Electric motors are core devices that convert electrical energy into mechanical energy and are widely used in industry, transportation, and daily life. Their operating principle is based on electromagnetic induction, with the stator windings generating a rotating magnetic field to drive the rotor. Depending on the power supply type, they are mainly divided into DC motors and AC motors. Variable frequency motors, which can adjust their speed by varying the power supply frequency, are widely used in many areas of modern industry and life.

[0003] The patent application with application number CN201520608150.0 discloses an energy-saving, stable variable frequency motor, including a base, a stator, a rotor and a bearing. The stator is fixedly arranged in the base, and the rotor is rotatably arranged in the base. A bearing is provided in the middle of the base, and a frequency converter is also provided on the base. The frequency converter is connected to the base through a wire. The energy-saving, stable variable frequency motor described in the device has a reasonable structure, reliable performance, high working efficiency, good heat dissipation effect, intelligent control, energy saving and environmental protection, labor-saving and time-saving, stable operation and long service life.

[0004] When existing equipment is in use, a common energy-saving method is to use the force generated by the rotation of the motor to transmit excess power to the power generation equipment. The electricity generated by the power generation equipment can reduce the electricity consumption required for subsequent motor operation to a certain extent, thereby achieving the purpose of energy saving. However, this energy-saving method will weaken the power output of the motor itself in the process of converting the force of the motor into electrical energy. This means that when the motor drives the equipment to operate, the effective power provided is insufficient, which in turn has an adverse effect on the normal use of the equipment. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a variable frequency motor with energy-saving effect to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a variable frequency motor with energy-saving effect, comprising a motor, wherein the output end of the motor is fixedly connected to a drive shaft, the outer wall of the motor is fixedly connected to a support plate, the end of the support plate away from the first hollow column is fixedly connected to the second hollow column, the outer wall of the second hollow column is rotatably connected to a rotating assembly via a bearing, and further comprising: An energy-saving mechanism includes a connecting ring three rotatably connected to the outer wall of the hollow column two through a bearing, the inner wall of the connecting ring three is fixedly connected to the fan blade two, and the inner wall of the fan blade two is fixedly connected to the connecting plate. The airflow generated by the rotation of the rotating component plays a role in controlling the rotation of the fan blade two. By setting up the energy-saving mechanism, the traditional method of using a connecting rod to connect and drive the electric energy compensation equipment is abandoned. Instead, mechanical energy is first converted into wind energy, and the wind energy is used to drive the fan blade two to rotate, and then the mechanical energy generated by the rotation of the fan blade two is converted into electric energy. This energy conversion method effectively avoids direct contact between the electric energy compensation equipment and the output end of the motor, thereby avoiding interference of the electric energy compensation equipment on the normal drive of the motor. In this way, the goal of energy saving is successfully achieved while ensuring that the normal operation of the equipment is not affected.

[0007] According to the above technical solution, the rotating component includes a connecting ring 1, the inner wall of the connecting ring 1 is fixedly connected to the drive shaft, the outer wall of the connecting ring 1 is rotatably connected to the hollow column 1 through a bearing, the outer wall of the connecting ring 1 is fixedly connected to the fan blade 1, the outer wall of the hollow column 2 is rotatably connected to the connecting ring 2 through a bearing, and the inner wall of the connecting ring 2 is fixedly connected to the fan blade 1. As the motor starts, the fan blade 1 will be driven to rotate, thereby sucking external air into the interior of the device.

[0008] According to the above technical solution, an air inlet is provided on the outer wall of the hollow column 2, and the air inlet passes through the hollow column 2 and extends to the inner wall of the hollow column 2. A baffle is provided on the outer side of the air inlet, and the inner wall of the baffle is fixedly connected to the hollow column 2. The air inlet is used to increase the air intake of external gas, and the baffle plays a role in controlling the direction of gas entry. By setting the air inlet and the baffle, during the operation of the equipment, the raised ring can accelerate the airflow. However, the air inlet of the fan blade 1 will be blocked by other components driven by the motor. This blocking reduces the amount of gas that can enter the front end of the fan blade. In order to ensure that there is sufficient airflow inside the equipment to maintain a good operating state, an air inlet is set on the outside of the equipment to increase the air intake. At the same time, the baffle can effectively block external debris from entering the interior of the equipment, avoiding damage or blockage to equipment components by debris, thereby ensuring the normal operation of the equipment.

[0009] According to the above technical solution, the outer wall of the hollow column is fixedly connected with a heat dissipation ring, and the outer wall of the motor is fixedly connected to the heat dissipation ring. The outer wall of the heat dissipation ring is equidistantly arranged with a plurality of heat dissipation fins, which enhance the heat dissipation effect through the flow of air. By setting the heat dissipation ring, when the equipment uses wind energy as a medium to achieve energy-saving operation, the flowing airflow also plays a role in cooling the motor body in this process. The existence of the heat dissipation ring enables the motor to be in a reasonable temperature range during operation, effectively avoiding the problem of motor power reduction caused by high temperature. Since the motor can stably maintain a good operating state, the additional energy loss caused by insufficient power is reduced, and the stability of the equipment operation is also fully guaranteed.

[0010] According to the above technical solution, the outer wall of the hollow column 1 away from the air inlet is fixedly connected with a raised ring, the outer wall of the raised ring is fixedly connected with a guide plate, and the inner wall of the hollow column 2 is fixedly connected to the guide plate. The guide plate plays a role in controlling the direction of airflow. By setting the guide plate and the raised ring, when the airflow enters the device, the airflow path is compressed under the action of the raised ring, thereby increasing the flow speed of the gas. The guide plate can guide the gas to flow in the direction of the fan blade deflection during this process. In this way, when the fan blade 2 rotates, the gas can push the fan blade 2 to rotate more smoothly, so the rotation speed of the fan blade 2 is accelerated. As the rotation speed of the fan blade 2 increases, the value of the mechanical energy generated by it also increases accordingly. The increase in mechanical energy means that more energy can be converted into electrical energy, thereby improving the overall energy-saving effect.

[0011] According to the above technical solution, the outer wall of the hollow column two is fixedly connected to the hollow column three, the end of the hollow column three away from the hollow column two is fixedly connected to the outer shell, the end of the connecting ring three away from the hollow column two is rotatably connected to the outer shell through a bearing, the end of the outer shell away from the hollow column two is fixedly connected to the bottom plate, and the side of the bottom plate close to the hollow column two is fixedly connected to the hollow column four, and the hollow column three is arranged on the outside of the connecting ring three to protect the connecting ring three.

[0012] According to the above technical solution, the front and rear sides of the fan blade 2 are fixedly connected with a connecting ring 4, the end of the hollow column 1 away from the fan blade 1 is rotatably connected to the connecting ring 4 through a bearing, and the end of the hollow column 4 away from the base plate is rotatably connected to the connecting ring 4 through a bearing. The connecting ring 4 is located between the ventilation port of the fan blade 2 and the interior of the device, and plays a role in blocking the overflow of airflow.

[0013] According to the above technical solution, the inner wall of the hollow column four is fixedly connected to an energy storage device, the power generation unit of the energy storage device is fixedly connected to the connecting plate, and a circular hole is opened on the side of the bottom plate away from the outer shell. The circular hole passes through the bottom and extends to the interior of the outer shell. The energy storage device will convert the mechanical energy generated by the rotation of the fan blade two into electrical energy and store it inside the energy storage device.

[0014] Compared with the prior art, the present invention provides a variable frequency motor with energy-saving effect, which has the following beneficial effects: 1. The present invention abandons the traditional method of using a connecting rod to drive the electric energy compensation device by setting an energy-saving mechanism. Instead, it first converts mechanical energy into wind energy, uses the wind energy to drive the second fan blade to rotate, and then converts the mechanical energy generated by the rotation of the second fan blade into electric energy. This energy conversion method effectively avoids direct contact between the electric energy compensation device and the output end of the motor, thereby avoiding the interference of the electric energy compensation device on the normal drive of the motor. In this way, the goal of energy saving is successfully achieved while ensuring that the normal operation of the equipment is not affected.

[0015] 2. The present invention sets a heat dissipation ring. When the equipment uses wind energy as a medium to achieve energy-saving operation, the flowing airflow also plays a role in cooling the motor body in this process. The existence of the heat dissipation ring enables the motor to be in a reasonable temperature range during operation, effectively avoiding the problem of motor power reduction caused by high temperature. Since the motor can stably maintain a good operating state, the additional energy loss caused by insufficient power is reduced, and the stability of the equipment operation is also fully guaranteed.

[0016] 3. The present invention sets a guide plate and a raised ring. When the air flow enters the device, the air flow path is compressed under the action of the raised ring, thereby increasing the flow speed of the gas. The guide plate can guide the gas to flow in the direction of the fan blade deflection during this process. In this way, when the fan blade 2 rotates, the gas can push the fan blade 2 to rotate more smoothly, so the rotation speed of the fan blade 2 is accelerated. As the rotation speed of the fan blade 2 increases, the value of the mechanical energy generated by it also increases accordingly. The increase in mechanical energy means that more energy can be converted into electrical energy, thereby improving the overall energy-saving effect.

[0017] 4. The present invention sets an air inlet and a baffle. During the operation of the equipment, the raised ring can accelerate the airflow. However, the air inlet of the fan blade will be blocked by other components driven by the motor. This blocking reduces the amount of gas that can enter the front end of the fan blade. In order to ensure sufficient airflow inside the equipment to maintain a good operating state, an air inlet is set on the outside of the equipment to increase the air intake. At the same time, the baffle can effectively block external debris from entering the interior of the equipment, preventing debris from damaging or clogging the equipment components, thereby ensuring the normal operation of the equipment.
