Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a high-efficiency electrical slip ring. Background Technique

[0002] An electrical slip ring is an electrical component responsible for connecting and transporting energy and signals to a rotating body. According to the transmission medium, slip rings are divided into electrical slip rings, fluid slip rings, and smooth slip rings, and can also be generally referred to as "rotary connection" or "rotary connection"; slip rings are usually installed at the rotation center of the equipment and mainly consist of two major parts: rotation and rest. The rotating part is connected to the rotating structure of the equipment and rotates with it, called the "rotor", and the stationary part is connected to the energy of the fixed structure of the equipment, called the "stator";

[0003] For the stator part of the electrical slip ring, it generally needs to be connected to the corresponding equipment through multiple wires. As a result, during the operation of the electrical slip ring, the wires connected to the equipment are prone to being entangled together, leading to loose wire connections. Moreover, when the wires are entangled together, it is also easy to cause a short circuit, posing a safety hazard and unable to guarantee the safety of the staff;

[0004] The traditional solution is to fix the wires to the stator part through fastening devices such as bolts. However, these fastening devices generally need to adjust the fixing degree according to the different thicknesses of the wires, which not only has a large adjustment difficulty but also a low adjustment efficiency;

[0005] Moreover, when the electrical slip ring is operating, a certain amount of metal powder will be generated inside the rotor of the slip ring due to wear. When the metal powder accumulates to a certain extent, it will affect the operation of the electrical slip ring;

[0006] The traditional solution is to clean the inside of the rotor regularly, but this method will cause the electronic slip ring to need to stop frequently, affecting its working efficiency;

[0007] Chinese Patent (CN107128555A) discloses an electrical slip ring structure for a food packaging machine, which realizes the passage of air and water circuits through a water-air slip ring and a slip ring shaft. During the rotation process, the air pipe and water pipe will not be entangled; however, this structure still cannot solve the influence caused by the metal powder during the operation of the electrical slip ring;

[0008] Therefore, we propose an electrical slip ring that can improve the wire fixing efficiency and can clean the metal powder in a timely manner. Utility Model Content

[0033] The technical solution of the present utility model will be described below in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, they only correspond to the accompanying drawings of the present utility model. For the convenience of describing the present utility model, it does not indicate or imply that the device or element referred to must have a specific orientation:

[0034] Embodiment 1 is as follows:

[0035] Combined with the attached Figure 1 An efficient electrical slip ring described above includes a housing 1, a stator body 2, a dust suction mechanism 3 and a fixing mechanism 4. The head end of the housing 1 is provided with a stator body 2, and the stator body 2 is fixedly connected to multiple wires 6 of the device through the fixing mechanism 4, and can be directly connected to the wires 6 of the device without additional wires 6, thereby avoiding the possible hazards caused by wire entanglement;

[0036] A rotor body is provided inside the housing 1, and an installation hole 11 is provided on the outer wall surface of the housing 1. The inside of the housing 1 is a hollow structure, and the rotor body inside the housing 1 is arranged in the cavity and will not come into contact with the inner wall of the housing 1. When the electrical slip ring is running, the housing 1 does not rotate;

[0037] The dust suction mechanism 3 is correspondingly connected to the installation hole 11, and the dust suction mechanism 3 is used to suck the metal powder inside the housing 1. The connection method between the dust suction mechanism 3 and the installation hole 11 can be plug connection, threaded connection or snap connection. All three can firmly connect the two, but the plug connection is the fastest, the threaded connection has good sealing performance, and the snap connection is more stable. However, the threaded connection and snap connection methods require modification of the parts where the dust suction mechanism 3 and the installation hole 11 are connected. Therefore, the optimal choice is still the plug connection method.

[0038] Embodiment 2 is as follows:

[0039] On the basis of Embodiment 1, combined with the attached Figure 2 , the dust suction mechanism 3 includes a dust suction housing 31. The tail end of the dust suction housing 31 is correspondingly plugged into the installation hole 11. A dust suction sticky net 32 is provided inside the dust suction housing 31. A dust removal fan 33 is provided between the dust suction sticky net 32 and the head end of the dust suction housing 31. A dust removal motor 34 connected to the dust removal fan 33 is provided at the head end of the dust suction housing 31, and a first air hole 311 is provided on the head end surface of the dust suction housing 31;

[0040] The dust removal motor 34 drives the dust removal fan 33 to rotate, sucking away the air containing metal powder inside the housing 1. Then the dust suction sticky net 32 will stick the metal powder in the sucked air to complete the dust removal inside the housing 1, and the clean air will be discharged from the first air hole 311;

[0041] It should be noted that since the metal powder generated by the rotor body will not affect the operation of the electrical slip ring when the quantity is small, the dust removal mechanism does not work continuously but intermittently. Moreover, when the first dust removal mechanism extracts the gas in the housing 1, the air pressure in the housing 1 will be reduced instantaneously. However, external gas will also enter the housing 1 from the first air holes 311 simultaneously to maintain the air pressure balance in the housing 1. The process of gas entering from the first air holes 311 is just the flow of gas during the air pressure balance process and is not affected by the operation of the dust removal mechanism.

[0042] Embodiment 3 is as follows:

[0043] On the basis of Embodiment 2, a semi-circular opening 312 corresponding to the dust-absorbing sticky net 32 is provided on the body of the dust-absorbing housing 31. The dust-absorbing sticky net 32 can be taken out from the opening 312, which is convenient for replacing the dust-absorbing sticky net 32. Moreover, a handle can be provided on the side of the dust-absorbing sticky net 32, and the handle extends out from the opening 312. In this way, workers can pull the handle to draw out the dust-absorbing sticky net 32, further improving the convenience.

[0044] Particularly, a plurality of convex rings 35 are sleeved on the tail end of the dust-absorbing housing 31. The plurality of convex rings 35 can increase the friction force when the dust-absorbing housing 31 is inserted into the mounting hole 11, thereby improving the firmness after the two are inserted.

[0045] Embodiment 4 is as follows:

[0046] On the basis of Embodiment 1, in combination with the attached Figures 3 - 4 , the fixing mechanism 4 includes a mounting base 41. A circuit connector 42 is provided at the tail end of the mounting base 41, and the circuit connector 42 is electrically connected to the stator body 2. A plurality of electrical jacks 43 are evenly provided at the head end of the mounting base 41, and a wire fixing component 44 for fixing the wire 6 is inserted into each electrical jack 43;

[0047] Among them, the inside of the mounting base 41 can conduct electricity. Through the mounting base 41 and the wire fixing component 44, not only can the wire 6 be fixed, but also the electrical signal emitted by the wire 6 can be transmitted to the stator body 2. And through the plurality of wire fixing components 44, multiple wires 6 can also be fixed separately, thereby improving the fixing effect on each wire 6.

[0048] Embodiment 5 is as follows:

[0049] Based on Embodiment 4, the wire fixing assembly 44 includes an electrical plug head 441 and a wire fixing part 442. The electrical plug head 441 is inserted into the corresponding jack. The wire fixing part 442 is provided with a cavity inside, and a through hole communicating with the cavity is provided at one end of the wire fixing part 442. A plurality of springs 443 are evenly arranged in a ring on the inner wall of the cavity of the wire fixing part 442. The head ends of the plurality of springs 443 all face the same center of the circle, and arc-shaped pressing plates 444 corresponding to abutting against the wire 6 are provided at the head ends of the springs 443.

[0050] The plurality of arc-shaped pressing plates 444 will abut against each other under the action of the springs 443 to form a hollow cylinder structure. Then, when the wire 6 of the device enters the wire fixing part 442 from the through hole under the action of an external force, it will pass through the hollow cylinder structure. And after the wire 6 reaches the electrical plug head 441 and the external force is removed, the wire 6 will be fixed by the plurality of arc-shaped pressing plates 444. It should be noted that the plurality of arc-shaped pressing plates 444 fix the wire 6 jointly by the frictional force generated between the inner wall surface and the surface of the wire 6 and the elastic force of the springs 443.

[0051] In addition, if the diameter of the wire 6 is relatively large, when the wire 6 extends into the hollow cylinder structure, it will push the plurality of arc-shaped pressing plates 444 outwards. However, the arc-shaped pressing plates 444 still adhere to the surface of the wire 6 under the action of the corresponding springs 443, thereby fixing the wire 6.

[0052] In addition, a fastening sleeve is connected to the outside of the through hole end of the wire fixing part by a thread to further fix the wire.

[0053] Embodiment 6 is as follows:

[0054] Based on Embodiment 1, a plurality of installation holes 11 are provided. The dust removal mechanism is correspondingly connected to a certain installation hole 11. The dust removal mechanism can replace the installation hole 11 according to the actual needs, so as to achieve the best dust removal effect.

[0055] In addition, a heat dissipation mechanism 5 is provided on the outer wall surface of the housing 1. The heat dissipation mechanism 5 is correspondingly connected to a certain installation hole 11. The heat dissipation mechanism 5 can also replace the installation hole 11 according to the actual needs, so as to achieve the best heat dissipation effect.

[0056] It should be noted that the heat dissipation mechanism 5, like the dust removal mechanism, adopts a plug-in method, and a plurality of convex rings 35 are also provided on the heat dissipation shell 51 to increase the frictional force between the plug-in and the installation hole 11 and improve the firmness of the plug-in.

[0057] Embodiment 7 is as follows:

[0058] Based on Embodiment 6, in combination with the attached Figure 5, the heat dissipation mechanism 5 includes a heat dissipation shell 51, a heat dissipation fan 52 and a heat dissipation motor 53. The tail end of the heat dissipation shell 51 is connected to the corresponding mounting hole 11. A heat dissipation fan 52 is provided inside the heat dissipation shell 51, and a heat dissipation motor 53 connected to the heat dissipation fan 52 is provided at the head end of the heat dissipation shell 51. Moreover, a second air hole 511 is provided on the head end face of the heat dissipation shell 51; according to the forward and reverse rotations of the drive motor being different, by driving the heat dissipation fan to rotate through the heat dissipation motor 53, the hot air in the housing 1 can be drawn away and discharged from the second air hole 511 to achieve the heat dissipation effect. Also, the external air can be inhaled to form an air flow to conduct air cooling on the rotor body in the housing 1, and the blown air flow is then discharged from the dust removal mechanism to form the flow of air and achieve the heat dissipation effect.

[0059] Specifically, a plurality of anti-slip rings 54 are sleeved on the outer wall surface of the heat dissipation shell 51, which are used to increase the friction when the heat dissipation shell 51 is held, facilitating the plugging operation between the heat dissipation shell 51 and the outer shell.

For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
