Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a shaded-pole motor for a water pump. Background Technology

[0002] As a key piece of equipment that converts electrical energy into mechanical energy to drive water pumps for liquid transportation, water pump motors play an indispensable role in many fields. In today's society, water pump motors are widely used in various sectors. In agricultural irrigation, they bear the heavy responsibility of transporting water and ensuring crop growth, which is of great significance for improving agricultural production efficiency and ensuring food security. In municipal water supply, high-power water pump motors are used to lift and transport water resources to meet the water needs of urban residents and industrial users. In industrial production, industries such as chemical, pharmaceutical, and food processing rely on water pump motors to transport and pressurize liquids, maintaining the continuity and stability of the production process. In building engineering, they ensure the normal operation of buildings in water supply, drainage, and HVAC systems. In household and small-scale applications, such as small domestic water pumps and aquarium circulation systems, water pump motors, with their simple structure and convenient operation, are indispensable.

[0003] When existing technical solutions are used,

[0004] (1) Its motor has poor heat dissipation performance. During long-term operation, the heat generated inside the motor is difficult to dissipate quickly, which will cause the motor temperature to rise, thereby affecting the motor's working efficiency and service life.

[0005] (2) The filtration structure of the water pump is not perfect enough. Impurities in the water can easily enter the water pump, causing wear on components such as the impeller and reducing the pumping effect and stability of the water pump.

[0006] To address the above problems, this utility model provides a shaded-pole motor for water pumps. Utility Model Content

[0007] The purpose of this invention is to solve the problems of poor motor heat dissipation and imperfect water pump filtration structure in the prior art, and to propose a shaded-pole motor for water pumps.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a shaded-pole motor for a water pump, comprising a connecting plate, a motor mechanism, a water pump mechanism, and a connecting support mechanism, wherein the motor mechanism is fixedly connected to the interior of the connecting plate, and the motor mechanism includes a base fixedly connected to the interior of the connecting plate.

[0009] The motor mechanism includes a short-circuit ring and a fan wheel, with the short-circuit ring fixedly connected inside the motor mechanism.

[0010] The base has a running winding fixedly connected inside, and the short-circuit ring is fixedly connected to the outer surface of the running winding. The running winding and the short-circuit ring are arranged at four equal intervals inside the base. The base has a rotor fixedly connected inside, and a coil is fixedly connected to the bottom of the base. The impeller is rotatably connected to one end of the rotor. The outer surface of the impeller is fixedly connected to a mesh cover, and the mesh cover is fixedly connected to the outer surface of the base.

[0011] Furthermore, a rotating shaft is fixedly connected to the other end of the rotor, and a bearing is rotatably connected to the outer surface of the rotating shaft, the bearing being fitted inside the water pump mechanism.

[0012] Furthermore, a fixing plate is fixedly connected to the outer surface of the base, and the outer surface of the fixing plate is fixedly connected to the outer surface of the connecting plate. The base is fixedly connected to both sides of the connecting plate through the fixing plate.

[0013] Furthermore, the water pump mechanism includes a base plate fixedly connected to the outer surface of the bearing, a locking block fixedly connected to the outer surface of the base plate, and the bearing being fitted into the center of the base plate.

[0014] Furthermore, the water pump mechanism includes a drainage plate fixedly connected to the top of the rotating shaft, the drainage plate being rotatably connected to the top of the base plate, a top plate being snapped onto the outer surface of the base plate, and a buckle being fixedly connected to the bottom of the top plate. The top plate and the base plate are snapped together by the snap blocks and buckles.

[0015] Furthermore, a through hole is provided at the center of the outer surface of the top plate, and a filter screen plate is threadedly connected to the outer surface of the through hole.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting up a short-circuit ring, bearings, and a fan, when the running winding of the motor is energized and generates an alternating magnetic field, the short-circuit ring will induce a current. The magnetic field generated by this current interacts with the magnetic field generated by the running winding, thereby generating a rotating magnetic field that drives the motor rotor to rotate. The bearings reduce the rotational friction of the rotating shaft and improve the transmission efficiency. The fan rotates under the drive of the rotor, allowing the heat generated by the motor to be carried away by air convection and dissipated into the surrounding environment, effectively reducing the motor temperature. Combined with the mesh cover, it effectively improves the heat dissipation performance of the motor, reduces the operating temperature of the motor, and extends the service life of the motor.

[0020] 2.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a shaded pole motor for a water pump, including a connecting plate 1, a motor mechanism 2, a water pump mechanism 3 and a connecting support mechanism 4. The motor mechanism 2 is fixedly connected to the inside of the connecting plate 1, and the motor mechanism 2 includes a base 21 fixedly connected to the inside of the connecting plate 1.

[0030] The specific setup and function of its motor mechanism 2, water pump mechanism 3, and connecting support mechanism 4 will be explained below.

[0031] In this embodiment: the motor mechanism 2 includes a short-circuit ring 22 and a fan wheel 23, with the short-circuit ring 22 fixedly connected inside the motor mechanism 2.

[0032] The running winding 24 is fixedly connected inside the base 21. The short-circuit ring 22 is fixedly connected to the outer surface of the running winding 24. The running winding 24 and the short-circuit ring 22 are arranged at four equal intervals inside the base 21. The rotor 25 is fixedly connected inside the base 21. The coil 26 is fixedly connected to the bottom of the base 21. The impeller 23 is rotatably connected to one end of the rotor 25. The outer surface of the impeller 23 is fixedly connected to the mesh cover 27. The mesh cover 27 is fixedly connected to the outer surface of the base 21.

[0033] The effects achieved by the above components are as follows: the running winding 24, short-circuit ring 22, rotor 25, coil 26, impeller 23 and mesh cover 27 work together to enable the motor to efficiently convert electrical energy into mechanical energy, drive the impeller 23 to rotate for heat dissipation, and the mesh cover 27 can protect the impeller 23 from interference from external objects, while guiding airflow so that the airflow generated by the impeller 23 can more effectively dissipate heat from the motor, ensure that the motor operates at a suitable temperature, and extend the service life of the motor.

[0034] Specifically, a rotating shaft 28 is fixedly connected to the other end of the rotor 25, and a bearing 29 is rotatably connected to the outer surface of the rotating shaft 28. The bearing 29 is fitted inside the water pump mechanism 3.

[0035] The effect achieved by the above components is as follows: through the cooperation of the rotating shaft 28 and the bearing 29, the mechanical energy generated by the motor mechanism 2 is efficiently transmitted to the water pump mechanism 3. The bearing 29 can reduce the frictional resistance when the rotating shaft 28 rotates, making the rotation smoother, reducing energy loss, and ensuring the stability and low energy consumption of the power transmission process.

[0036] Specifically, a fixing plate 210 is fixedly connected to the outer surface of the base 21. The outer surface of the fixing plate 210 is fixedly connected to the outer surface of the connecting plate 1. The base 21 is fixedly connected to both sides of the connecting plate 1 through the fixing plate 210.

[0037] The above components achieve the following effects: the fixing plate 210 serves to firmly connect the base 21 and the connecting plate 1, just like a motor mounting base, ensuring that the motor mechanism 2 remains stable during operation, reducing vibration, providing good installation and support conditions for the motor mechanism 2, and ensuring stable operation of the motor.

[0038] Specifically, the water pump mechanism 3 includes a base plate 31 fixedly connected to the outer surface of the bearing 29, a locking block 32 fixedly connected to the outer surface of the base plate 31, and the bearing 29 being fitted into the center of the base plate 31.

[0039] The effects achieved by the above components are as follows: the base plate 31 provides a basic support structure for the water pump mechanism 3, the locking block 32 is used for subsequent locking and fixing with other components, and the bearing 29 is fitted into the center of the base plate 31 to ensure the coaxiality of the connection between the rotating shaft 28 and the water pump mechanism 3, making the power transmission more stable and efficient.

[0040] Specifically, the water pump mechanism 3 includes a drainage plate 33 fixedly connected to the top of the rotating shaft 28, the drainage plate 33 being rotatably connected to the top of the base plate 31, a top plate 34 being snapped onto the outer surface of the base plate 31, and a buckle 35 being fixedly connected to the bottom of the top plate 34. The top plate 34 and the base plate 31 are snapped together by a locking block 32 and a buckle 35.

[0041] The effects achieved by the above components are as follows: the drainage plate 33 can apply force to the water during rotation, promote water flow, and realize the drainage function. The drainage plate 33 realizes the drainage function of the water pump. The top plate 34 and the bottom plate 31 are connected by the locking block 32 and the buckle 35, which not only ensures the integrity of the water pump structure, but also provides a convenient maintenance method.

[0042] Specifically, a through hole 36 is provided at the center of the outer surface of the top plate 34, and a filter screen plate 37 is threadedly connected to the outer surface of the through hole 36. Bolts 38 are threadedly connected to both sides of the filter screen plate 37, and the filter screen plate 37 is threadedly connected to the outer surface of the top plate 34 by the bolts 38.

[0043] The effects achieved by the above components are as follows: the filter screen 37 can filter the water entering the water pump, preventing impurities and particles in the water from entering the water pump, avoiding these impurities from causing wear or blockage to components such as the drain plate 33, affecting the normal operation of the water pump, and at the same time facilitating the maintenance of the filter screen 37, ensuring the long-term stable operation of the water pump.

[0044] Specifically, a connecting support plate 39 is fixedly connected to the outer surface of the top plate 34, a limiting plate 310 is fixedly connected to the far end of the connecting support plate 39, the outer surface of the limiting plate 310 is fixedly connected to the outer surface of the connecting plate 1, and a water suction pipe 311 is fixedly connected to the bottom of the outer surface of the top plate 34.

[0045] The above components achieve the following effects: they enhance the stability of the connection between the water pump mechanism 3 and the connecting plate 1, while the suction pipe 311 enables the introduction of water source, ensuring that the water pump can perform water suction and drainage work normally.

[0046] Specifically, the connecting support mechanism 4 includes a support block 41 fixedly connected to the bottom of the connecting plate 1 and the top plate 34. Ground connectors 42 are threadedly connected to both sides of the support block 41, and the ground connectors 42 are symmetrically arranged on the support block 41.

[0047] The effect achieved by the above components is that the support block 41 can be firmly fixed to the ground through the ground connector 42, preventing the device from shifting or tipping over due to vibration or external force during operation, and ensuring the safety and stability of the entire device operation.

[0048] Working principle: When the motor mechanism 2 is energized, the current passes through the running winding 24 to generate an alternating magnetic field. The short-circuit ring 22 generates eddy currents due to the alternating magnetic flux, which in turn generates hysteresis flux. This flux is superimposed with the magnetic flux of the running winding 24 to form a stable rotating magnetic field, which drives the rotor 25 to rotate.

[0049] The rotor 25 drives the rotating shaft 28 and the impeller 23 to rotate. The rotation of the impeller 23 generates airflow to cool the motor. At the same time, the rotating shaft 28 drives the drain plate 33 in the water pump mechanism 3 to rotate. External water enters through the suction pipe 311. The rotation of the drain plate 33 applies force to the water to make it flow. After impurities are filtered by the filter screen 37, the water is discharged.

[0050] The support block 41 connecting the support mechanism 4 and the ground connector 42 ensure that the entire device is placed stably and fixed to the ground. All mechanisms work together to realize the water pump's pumping function.
