Description

Technical Field

[0001] This utility model relates to the field of water pump motor technology, specifically to a water pump motor slip ring. Background Technology

[0002] Slip rings, also known as conductor rings, slip rings, current collectors, or collector rings, can be used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. Slip rings can improve system performance, simplify system structure, and prevent wires from twisting during rotation.

[0003] After prolonged use, both the conductive slip ring and brush of existing water pump motor slip rings will experience wear. Although the commonly used elastic brushes can improve this problem, using the elasticity of the brush to control the contact will maximize the wear when the elastic force is sufficient in the early stage. At the same time, the contact force will gradually decrease in the later stage of wear, affecting the stability of the contact connection. Therefore, we propose a new slip ring for water pump motors. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A slip ring for a water pump motor includes a drive shaft, a conductive slip ring mounted in the middle of the drive shaft, and a brush disposed on the side of the conductive slip ring. A connecting assembly is provided on the side of the brush. The connecting assembly includes a wiring mechanism connected to the end of the brush, a clamping mechanism disposed on the side of the wiring mechanism, and an adjusting mechanism disposed inside the clamping mechanism. The wiring mechanism includes a terminal block fixed to the outer end of the brush and a connecting wire connected to the end of the terminal block. The clamping mechanism includes an insulating block fitted on the terminal block, a clamping plate placed on the insulating block, a cover plate fixed above the clamping plate, a protective cover for mounting the cover plate, a spring fixed to the bottom of the protective cover and connected to the terminal block, and an electric telescopic rod installed in the middle of the cover plate.

[0007] In a preferred embodiment, the present invention can be further configured such that the adjustment mechanism includes an adjustment shaft installed inside the protective cover, an adjustment bracket fixed on the adjustment shaft, a positioning plate inserted between the adjustment brackets, and a positioning hole opened on the positioning plate for the brush to pass through.

[0008] In a preferred embodiment, the present invention can be further configured such that the clamping sheet is a W-shaped elastic sheet structure.

[0009] In a preferred embodiment, the present invention can be further configured such that a positioning groove is provided in the middle of the pressing plate.

This device has a long service life and higher stability.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a slip ring for a water pump motor.

[0024] Combination Figure 1-2 As shown, the present invention provides a pump motor slip ring, including a drive shaft 110, a conductive slip ring 120 installed in the middle of the drive shaft 110, and a brush 130 disposed on the side of the conductive slip ring 120. A connecting component 200 is provided on the side of the brush 130.

[0025] The connection assembly 200 includes a wiring mechanism connected to the end of the brush 130, a clamping mechanism disposed on the side of the wiring mechanism, and an adjustment mechanism disposed inside the clamping mechanism; the wiring mechanism includes a terminal block 210 fixed to the outer end of the brush 130 and a connecting wire 220 connected to the end of the terminal block 210; the clamping mechanism includes an insulating block 230 fitted on the terminal block 210, a clamping plate 240 placed on the insulating block 230, a cover plate 250 fixed above the clamping plate 240, a protective cover 260 for mounting the cover plate 250, and a mechanism fixed to the end of the brush 130. The spring 270 at the bottom of the protective cover 260 and connected to the terminal block 210, and the electric telescopic rod 280 installed in the middle of the cover plate 250, through the connecting assembly 200, can use the clamping plate 240 to clamp the terminal block 210 and the brush 130, so that the brush 130 is tightly attached to the conductive slip ring 120. After the conductive slip ring 120 and the brush 130 wear, the electric telescopic rod 280 will extend and push the clamping plate 240, so that the clamping plate 240 restores the thrust on the brush 130, so that the conductive slip ring 120 and the brush 130 are tightly attached again. This device has a long service life and higher stability.

[0026] Specifically, the adjustment mechanism includes an adjustment shaft 310 installed inside the protective cover 260, an adjustment bracket 320 fixed on the adjustment shaft 310, a positioning plate 330 inserted between the adjustment brackets 320, and a positioning hole 340 opened on the positioning plate 330 for the brush 130 to pass through. The tilt angle of the adjustment shaft 310 can be adjusted so that the brush 130 can better contact the conductive slip ring 120, which facilitates the adjustment of the contact area and has high practicality.

[0027] Furthermore, the clamping plate 240 has a W-shaped elastic plate structure, which has a better clamping effect and ensures that the brush 130 is tightly attached to the conductive slip ring 120.

[0028] Specifically, the clamping plate 240 has a positioning groove 241 in the middle, which can position the end of the electric telescopic rod 280 to prevent misalignment, thereby ensuring the stability of the subsequent deformation of the clamping plate 240 by the electric telescopic rod 280.

[0029] Furthermore, a limiting groove 231 is provided in the middle of the insulating block 230, which can provide a better positioning effect for the clamping plate 240.

[0030] Furthermore, the electric telescopic rod 280 is electrically connected to a controller, which is set in the control system of the water pump motor. It adopts a programmable logic controller (PLC) combined with a dedicated motion control module / card. The core processor is a high-performance industrial-grade microprocessor based on ARM Cortex-A or RISC architecture, located in the main control unit (CPU) of the PLC.

[0031] Control methods include setting working parameters (target position, speed, processing quantity, etc.), selecting programs, and starting / stopping the equipment via HMI (human-machine interface - touch screen);

[0032] The host computer system (such as SCADA, MES) sends control commands and recipe data through the network;

[0033] The signal transmission method is that the motion controller generates a pulse + direction signal (PUL / DIR) or an analog signal (±10V) and sends it to the servo drive via a high-speed industrial bus (such as EtherCAT, PROFINET IRT, CANopen).

[0034] The working principle and usage process of this utility model are as follows: First, the brushes 130 are fixed sequentially into the terminal block 210. Then, the brushes 130 are placed into the protective cover 260 from above, while the brushes 130 pass through the positioning hole 340 and contact the conductive slip ring 120. Then, the cover plate 250 is placed on top, so that the clamping plate 240 presses on the insulating block 230 to complete the fixation. After the conductive slip ring 120 and the brushes 130 wear out, a connection break may occur. Then, the controller will control the electric telescopic rod 280 to extend and push the clamping plate 240, so that the clamping plate 240 restores the pushing force on the brushes 130, thereby making the conductive slip ring 120 and the brushes 130 fit tightly again.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
