Description

Technical Field

[0001] The utility model relates to the technical field of synchronous water pump motors, and particularly relates to a slip ring for a synchronous water pump motor. Background Art

[0002] During the operation of a synchronous water pump motor, a continuous rotational motion is required to drive the water pump. At the same time, this rotational motion also needs to maintain an electrical connection with an external power source and control system to transmit necessary electrical energy and signals. The traditional wire connection method is prone to breakage due to winding during rotation, resulting in system instability or even failure. Therefore, a device that can stably transmit power and signals during rotation is needed, namely a slip ring for a synchronous water pump motor. Through the slip ring, a stable electrical connection can be achieved between the rotating part and the fixed part of the motor, reducing energy loss and signal interference caused by wire winding, thereby improving the operation efficiency and stability of the motor. Traditional motor systems often require complex wire layouts and connectors to achieve electrical connection between the rotating part and the fixed part. This not only increases the complexity and cost of the system, but also reduces the reliability and maintainability of the system. The slip ring can simplify this complex electrical connection into a compact and reliable component, thus simplifying the system structure and reducing the system cost. During the operation of a synchronous water pump motor, the slip ring needs to withstand large mechanical stresses and electrical loads. In summary, in order to improve system performance and simplify the system structure, a slip ring for a synchronous water pump motor is proposed to meet the operation requirements of the synchronous water pump motor. Content of the Utility Model

[0003] The utility model aims to solve at least to some extent the technical problems of the slip ring on a synchronous water pump motor. For this purpose, the utility model proposes a slip ring for a synchronous water pump motor.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a slip ring for a synchronous water pump motor, which specifically includes a slip ring main body. The slip ring main body includes a conductive rod, a connecting sleeve, a conductive component, an insulating component, and a fixing device. The connecting sleeve is connected to the conductive component. The conductive component includes a first conductive ring, a second conductive ring, a third conductive ring, and a fourth conductive ring. The connecting sleeve is axially sleeved with the first conductive ring, the second conductive ring, the third conductive ring, and the fourth conductive ring in sequence. The insulating components are arranged at intervals between the conductive rings. A conductive rod corresponding to each conductive ring is further sleeved outside the connecting sleeve, and the conductive rod is electrically connected to its corresponding conductive ring and insulated from other conductive rings. The fixing device includes a support block, a fixing side rod, and a positioning block. Two positioning blocks are connected to the insulating component, and the fixing side rod is connected to the positioning block. The two fixing side rods are fixedly arranged on the support block.

[0005] In a preferred embodiment of the present utility model, the insulating member includes a first insulating plate, a second insulating plate, a third insulating plate, and a fourth insulating plate. The first insulating plate, the second insulating plate, the third insulating plate, and the fourth insulating plate are sequentially arranged between adjacent conductive rings.

[0006] In a preferred embodiment of the present utility model, the number of the conductive rods is four, and each of the conductive rods is arranged around the outer side of the connecting sleeve at intervals.

[0007] In a preferred embodiment of the present utility model, a limiting thread is provided at the connection between the conductive rod and each conductive ring.

[0008] In a preferred embodiment of the present utility model, an internal connection thread is provided inside the connecting sleeve.

[0009] In a preferred embodiment of the present utility model, a limiting nut is provided on the exposed outer part of the conductive rod connecting the connecting sleeve.

[0010] The beneficial effects of the present utility model are as follows: After adopting the above structure, by sequentially sleeving a plurality of conductive rings through the connecting sleeve and arranging insulating members between the conductive rings, effective electrical isolation and conduction are achieved, making the entire slip ring structure compact and stable in performance. This design ensures the electrical independence between each conductive ring, avoids current crosstalk, and improves the reliability and safety of the motor operation; the setting of the insulating member effectively isolates adjacent conductive rings, prevents electrical short circuits, and enhances the insulation performance of the slip ring. This is particularly important for the motor to operate in a high-voltage and high-current environment, which can reduce energy loss and improve the motor efficiency. The number of conductive rods matches the number of conductive rings and is arranged around the outer side of the connecting sleeve at intervals, ensuring the electrical connection with the corresponding conductive rings and maintaining insulation from other conductive rings, simplifying the circuit structure, reducing the contact resistance, and improving the current transmission efficiency. The fixing device firmly fixes the insulating member and the conductive rings on the connecting sleeve, ensuring the overall stability and durability of the slip ring. Even in a vibrating or impact environment, the integrity of the structure and the reliability of the electrical connection can be maintained; due to the reasonable design of the connection structure between each component, when it is necessary to maintain or replace a certain conductive ring or insulating member, it can be conveniently disassembled and installed, reducing the maintenance cost and time. In summary, the slip ring of the synchronous water pump motor of the present utility model has the advantages of compact structure, stable performance, good insulation effect, reasonable design of conductive rods, firm fixing device, and easy maintenance and replacement, which can significantly improve the reliability and safety of the motor operation, reduce the failure rate, and extend the service life of the motor.

Specific embodiments

[0014] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0015] As Figure 1 and Figure 2As shown in the figure, a slip ring for a synchronous water pump motor, the slip ring for the synchronous water pump motor specifically includes a slip ring body. The slip ring body includes a conductive rod 1, a connecting sleeve 2, a conductive component, an insulating component, and a fixing device. The connecting sleeve 2 is connected to the conductive component. The conductive component includes a first conductive ring 3, a second conductive ring 4, a third conductive ring 5, and a fourth conductive ring 6. The connecting sleeve 2 is axially sleeved with the first conductive ring 3, the second conductive ring 4, the third conductive ring 5, and the fourth conductive ring 6 in sequence. The insulating component is arranged at intervals between the conductive rings. A conductive rod 1 corresponding to each conductive ring is also sleeved outside the connecting sleeve 2, and the conductive rod 1 is electrically connected to its corresponding conductive ring and insulated from other conductive rings. The fixing device includes a support block 7, a fixing side rod 8, and a positioning block 9. Two positioning blocks 9 are connected to the insulating component, and a fixing side rod 8 is connected to the positioning block 9. The two fixing side rods 8 are fixed on the support block 7. In implementation, the slip ring body is responsible for introducing external power into the motor to provide power for the operation of the motor. The conductive rod 1 ensures the uniformity and stability of current transmission; it is electrically connected to each conductive ring to ensure the effective transmission of current. At the same time, the insulation design between each conductive ring ensures the safety of current transmission and prevents short circuits; the connecting sleeve 2 serves as a support structure for the conductive component, axially sleeving each conductive ring in sequence to achieve step-by-step current transmission; the conductive component, the first conductive ring 3, the second conductive ring 4, the third conductive ring 5, and the fourth conductive ring 6 can flexibly adjust the current transmission path by arranging multiple conductive rings in layers to meet the requirements under different working conditions, and is made of a high-conductivity material to ensure the high efficiency of current transmission; the insulating component is arranged at intervals between the conductive rings to effectively isolate each conductive ring, prevent current leakage and short circuits, and ensure the safe operation of the motor; a high-insulation material is used to ensure stable insulation performance even under harsh working conditions; the fixing device combines the support block 7, the fixing side rod 8, and the positioning block 9 to firmly fix the slip ring body inside the motor, preventing displacement or damage caused by vibration or impact; the positioning block 9 is connected to the insulating component and fixed on the support block 7 through the fixing side rod 8 to form a stable support structure, ensuring the stability of the slip ring body during the operation of the motor.

[0016] As Figure 1As shown, further on the basis of the above method, the insulating component includes a first insulating plate 10, a second insulating plate 11, a third insulating plate 12, and a fourth insulating plate 13. The first insulating plate 10, the second insulating plate 11, the third insulating plate 12, and the fourth insulating plate 13 are sequentially arranged between adjacent conductive rings. In specific implementation, the main function of the insulating plate is to isolate adjacent conductive rings to prevent direct contact between them, thereby avoiding the occurrence of short-circuit phenomena. This is the key to ensuring the safe operation of the motor; through the isolation of the insulating plate, it is ensured that the current can only flow along a predetermined path (i.e., through the conductive ring and the conductive rod 1), and accidental leakage or short-circuit will not occur; the insulating plate can reduce the electromagnetic interference between conductive rings and between the conductive ring and the external environment, contribute to maintaining the stability of the electromagnetic field inside the motor, improve the operating efficiency of the motor, and help resist the influence of external factors such as vibration and impact.

[0017] As Figure 1 shown, further on the basis of the above method, the number of conductive rods 1 is four, and each conductive rod 1 is arranged around the outside of the connecting sleeve 2 at intervals. In implementation, the four conductive rods are evenly distributed on the outside of the connecting sleeve 2, which can ensure the uniform distribution of current during transmission. This helps reduce problems such as local overheating or damage caused by current concentration, and improves the operating efficiency and stability of the motor. The arrangement of multiple conductive rods 1 increases the conductive area, enabling the current to flow more smoothly during transmission. This helps reduce resistance, reduce energy loss, and improve conductive efficiency. By being arranged around the outside of the connecting sleeve, it provides a certain support and fixation function for the entire slip ring system. This helps enhance the structural stability of the slip ring and prevent displacement or damage caused by vibration or impact. During the operation of the motor, if one of the conductive rods fails or is damaged, the other conductive rods can still work normally to ensure the continuous transmission of current.

[0018] As Figure 1 shown, further on the basis of the above method, a limiting thread 14 is provided at the connection between the conductive rod 1 and each conductive ring. Through the tight fit of the thread, the conductive rod 1 is firmly fixed on the conductive ring, preventing loosening or detachment of the connection due to vibration or impact during the operation of the motor; the threaded connection allows a certain adjustment space, and the position of the conductive rod can be finely adjusted during installation to ensure its precise alignment with the conductive ring. Through the tight fit of the limiting thread 14, it can be ensured that the contact area between the conductive rod and the conductive ring is large enough, thereby reducing the contact resistance and improving the conductive performance.

[0019] As Figure 1As shown, further based on the above method, an internal connection thread 15 is provided inside the connecting sleeve 2. In a specific implementation, through the tight fit of the thread, the connecting sleeve 2 is firmly connected to other components (such as a motor shaft, a transmission device, etc.), ensuring that the motor will not loosen or fall off due to vibration or impact during operation; the threaded connection allows a certain adjustment space, and the position of the connecting sleeve can be finely adjusted during installation to ensure its precise alignment with the connected component, thereby improving the operation accuracy of the entire motor system. It reduces problems such as vibration and noise caused by loose connections.

[0020] As Figure 1 As shown, further based on the above method, a limit nut 16 is provided on the exposed outside of the conductive rod 1 connecting the connecting sleeve 2. In a specific implementation, the limit nut 16 provides additional fastening force by being tightened at the connection between the conductive rod 1 and the connecting sleeve 2, further strengthening the connection strength between the conductive rod 1 and the connecting sleeve 2. This design can effectively prevent the connection from loosening or falling off due to vibration or impact during the operation of the motor.

[0021] In the specific working process of the novel slip ring for a synchronous water pump motor, current introduction: The external power supply is connected to the conducting rod 1 of the slip ring body through a specific interface or connecting device. These conducting rods are the main channels for current to enter the motor interior. Current distribution and transmission: The current enters from the conducting rod 1 and first passes through the conducting ring directly connected to it (such as the first conducting ring 3). These conducting rings are made of high-conductivity materials, ensuring the high efficiency of current transmission. When the current is transmitted between the conducting rings, it is isolated by insulating components, preventing direct contact and short circuit between the conducting rings; the current passes through each conducting ring in sequence to achieve step-by-step transmission of the current. The fixing device firmly fixes the slip ring body inside the motor in a combined manner. This ensures the stability and reliability of the slip ring during the operation of the motor. The positioning block 9 is connected to the insulating component and fixed to the support block 7 through the fixed side rod 8, forming a stable support structure to effectively resist vibration and shock; the setting of the insulating component not only isolates the conducting rings but also prevents current leakage and short circuit, ensuring the safety of the motor operation. The insulation design between the conducting rod 1 and each conducting ring and the tight fit of the limiting thread 14 further ensure the safety and stability of current transmission. Current output: After the step-by-step transmission and distribution through each conducting ring, the current is finally converted into mechanical energy through other components inside the motor (such as the rotor, stator winding, etc.) to drive the water pump to work. Operation and maintenance: During the operation of the motor, regularly check the status of the slip ring and its connecting components to ensure that there is no looseness, wear, or damage. If necessary, replace the damaged conducting rod, conducting ring, or insulating component to ensure the long-term stable operation of the motor. In summary, through fine design and reliable connection, the novel slip ring for a synchronous water pump motor realizes the efficient and safe transmission of current, providing a strong guarantee for the stable operation of the motor.
