Description

Technical Field

[0001] This utility model relates to the field of collector rings, and more particularly to a central collector ring. Background Technology

[0002] A slip ring, also known as a current collector or rotary joint, is a precision mechanical component used to transmit current or signals. It mainly consists of two parts: a fixed brush assembly and a rotating conductive ring. The function of the slip ring is to achieve continuous and stable current or signal transmission between a rotating body and a stationary body, or between two relatively rotating parts. This device is widely used in various rotating equipment, such as radar antennas, wind turbines, medical equipment, automated robotic arms, rotating stages, etc. It ensures that the equipment can be powered or transmitted data without interruption while rotating, thereby guaranteeing the normal operation and functionality of the equipment. The design of slip rings usually needs to consider factors such as conductivity, wear resistance, corrosion resistance, and stability under high-speed rotation to meet the needs of different application scenarios.

[0003] A novel connecting device for a current collector ring is disclosed in Chinese patent document CN202320912579.3, comprising: a current collector ring stator mechanism; a current collector ring rotor mechanism, wherein the current collector ring rotor mechanism is rotatably mounted inside the current collector ring stator mechanism; and a stator heat dissipation mechanism, wherein the stator heat dissipation mechanism is installed outside the current collector ring stator mechanism and is used for heat dissipation and cooling of the current collector ring stator mechanism. In this invention, the current collector ring stator mechanism electrically contacts the brush contact ring of the current collector ring rotor mechanism via brush U-rods. After being subjected to force, the brush U-rods retract and move along the contact rods, and are reset by an insulating spring. This reduces the deformation of the brush U-rods within the current collector ring stator mechanism due to external pressure. When the current collector ring rotor mechanism rotates continuously, it collects heat inside the stator cylinder, and the stator cylinder conducts heat through heat dissipation fins. The heat dissipation mechanism's cooling fan further cools the interior of the stator cylinder.

[0004] However, the above-mentioned patent has certain defects in use. Because the interaction between the current collector ring body and the brush U rod may lead to increased friction and accelerated wear, if the brush wear is not detected and replaced in time in actual engineering applications, it will affect the transmission efficiency and the service life of the equipment.

[0005] To address these issues, a central flow-collecting loop is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a central flow ring.

[0007] This utility model is achieved using the following technical solution:

[0008] A central current collection loop, including

[0009] Main body of the current collection loop;

[0010] The support plate is provided in multiple ways. The multiple support plates are fixedly connected to the lower peripheral wall of the main body of the collecting ring. Each of the multiple support plates has a mounting hole through it.

[0011] A sleeve, wherein a plug is fixedly connected to the bottom of the sleeve, and multiple plugs are provided. The mounting holes and plugs are matched for installation. The multiple plugs fix the sleeve through the mounting holes. A reserved groove is provided inside the sleeve.

[0012] An electromagnetic coil is installed on the inner wall of a sleeve through a pre-reserved slot. The electromagnetic coil is fixedly connected to multiple connecting plates. Each of the multiple connecting plates has a first pre-reserved hole. A connecting guide block is provided in the first pre-reserved hole. A pressure detector is provided in the middle of one side of the connecting guide block. Second pre-reserved holes are provided on both sides of the connecting guide block.

[0013] The brush is provided in multiple parts, and each brush has multiple positioning posts on its back. The positioning posts are installed in conjunction with the second reserved hole, and the positioning posts fix the brush to the connecting plate through the second reserved hole.

[0014] As a preferred embodiment of this utility model, a conductive ring is fixedly connected to the outer wall of the current collecting ring body 5, and multiple conductive rings are provided.

[0015] As a preferred embodiment of this utility model, the top of the current collector ring body is provided with a cable outlet, and there are multiple cable outlets; the bottom of the current collector ring body is provided with a connection port, and there are multiple connection ports.

[0016] In a preferred embodiment of this utility model, a sleeve is installed on the plug block, and the sleeve and the plug block are a matching combination.

[0017] As a preferred embodiment of this utility model, the contact points between the sleeve and the main body of the collector ring are all rounded.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. By providing a pre-reserved groove inside the sleeve, the friction between the current collector ring and the brush can be reduced while ensuring structural strength. An electromagnetic coil is installed in the pre-reserved hole, which significantly improves the transmission efficiency. At the same time, the pressure detector on the connecting guide block can monitor the wear of the brush in real time. When the wear is too large, the system will stop operating, which effectively extends the service life of the equipment, reduces maintenance costs, and enhances the stability and reliability of the system.

[0020] 2. The mounting holes and inserts are installed together. The multiple inserts fix the sleeve through the mounting holes. The sleeve has a reserved groove inside. After the inserts are installed through the multiple mounting holes, the insert sleeve is installed at the end of the insert. This not only ensures the accurate installation of the electromagnetic coil, but also facilitates future maintenance and replacement.

[0021] 3. Multiple connecting plates are provided on the electromagnetic coil, and the first reserved hole is provided in the multiple connecting plates to facilitate the installation of the connecting guide block. The pressure detector is set on the connecting guide block, and the second reserved hole is provided on both sides of the pressure sensor to ensure accurate fixing and convenient replacement of the brush. The whole equipment is convenient for daily maintenance and improves the overall operating efficiency of the equipment. Attached Figure Description
