Description

Technical Field

[0001] The invention relates to the technical field of electric slip rings, and in particular to an electric slip ring contact assembly for a single point mooring system. Background Art

[0002] Single point mooring system high voltage electric slip ring is used in offshore floating power station, offshore oil and gas and offshore wind power, etc., to solve the problem of power transmission caused by the random rotation of floating power generation or power consumption terminals accompanied by waves. The sliding friction between the ring body and the brush can realize the continuous 360° transmission of electric energy and signals between the rotating mechanisms. The stability of the friction between the brush and the ring body determines many important performance parameters of the conductive slip ring, such as contact resistance and electrical noise. Therefore, improving the stability of the brush and the ring body during rotation is one of the important areas of research in recent years on how to improve the reliability and long life of the conductive slip ring.

[0003] There are two main problems with existing power slip ring devices. First, the contact area between the brush and the slip ring is small and the contact is insufficient, which makes it difficult to meet the stability requirements during current transmission. Second, the brush, as a wearable part, is not wear-resistant and difficult to replace, which makes it difficult to meet the requirements for long-term use of the power slip ring. Summary of the invention

[0004] The present application solves the problems of small contact area and insufficient contact between the brush and the slip ring in the prior art by providing an electric slip ring contact assembly for a single point mooring system, thereby meeting the stability requirements during current transmission.

[0005] The embodiment of the present application provides an electric slip ring contact assembly for a single point mooring system, comprising:

[0006] The brush base is provided with a groove;

[0007] An elastic shock absorbing mechanism, fixedly installed in the groove with bolts;

[0008] A slot mechanism, fixed to the elastic shock absorbing mechanism;

[0009] The brush is detachably installed in the slot mechanism, and includes an elastic base spring and a plurality of bionic accordion scale armor coat wear-resistant sheets. The bionic accordion scale armor coat wear-resistant sheets are sleeved on the support of the elastic base spring, and the support is inclined, and the plurality of bionic accordion scale armor coat wear-resistant sheets form a plurality of inclined contact surfaces.

[0010] The beneficial effect of the above embodiment is that the power slip ring contact assembly is generally arranged in pairs, and the power slip ring is sandwiched between two brushes arranged opposite to each other. Compared with the point contact between the traditional brush and the power slip ring, the brush of the power slip ring contact assembly forms multi-surface contact with the power slip ring through multiple inclined wear-resistant sheets, which greatly increases the contact area between the brush and the slip ring, and the contact is more complete, meeting the stability requirements during the current transmission process.

[0011] Based on the above embodiments, the present application can be further improved as follows:

[0012] In one of the embodiments of the present application, the surface of the bionic accordion scale armor coat wear-resistant sheet is composed of a bionic wear-resistant surface tissue and a lubricant, and the tissue pattern is a geometric groove array, and the lubricant is filled in the groove array. When the two contact surfaces of the brush and the conductive slip ring are in relative friction, the lubricant is squeezed out from the grooves of the bionic tissue to form a uniform and lasting lubricating film, thereby forming an effective lubricating layer on the friction interface, so that the contact surface obtains a good self-lubricating effect during operation, thereby significantly improving its wear resistance and extending the service life of the brush wear-resistant sheet; compared with traditional smooth wear-resistant brushes, the friction coefficient of the brush surface with bionic self-lubricating tissue is significantly reduced, which means less loss during friction, and the friction performance is significantly improved, which can solve the wear failure problem of the brush in long-term use under special working conditions.

[0013] In one embodiment of the present application, the slot mechanism includes a slot base and two limit rods, the slot base is horizontally fixed to the elastic shock absorbing mechanism; the slot base is provided with a slot for inserting the brush, the two limit rods are respectively nested and installed on both sides of the slot base, the elastic base spring sheet is provided with a limit slot, and the limit rod is provided with a limit buckle that cooperates with the limit slot. Compared with the traditional slide slot design, the slot mechanism in the power slip ring contact assembly uses a buckle design to lock the brush. When the brush assembly is excessively worn and needs to be replaced, the brush assembly can be easily disassembled and replaced without destroying the physical structure of the power slip ring device.

[0014] In one of the embodiments of the present application, the elastic shock absorbing mechanism includes a fixing bolt, a spring, a base plate and a guide limiter, the guide limiter is fixed on the base plate, the fixing bolt fixes the elastic shock absorbing mechanism to the brush base through the limit hole of the guide limiter, the spring is embedded in the guide limiter, one end is fixed to the limit hole of the guide limiter, and the other end is fixed to the fixing bolt. In view of the problem that the existing power slip ring is prone to poor contact or even circuit break during power transmission and is difficult to meet the needs of large current transmission, the elastic shock absorbing mechanism can realize the contact adaptive adjustment function between the brush and the conductive slip ring, avoiding the vibration impact of the equipment caused by the external environment or the excessive wear of the brush bionic scale armor wear-resistant sheet, resulting in poor contact and even circuit break between the brush and the conductive slip ring, and ensuring the stability and reliability of power transmission.

[0015] In one of the embodiments of the present application, a limiting hole is provided on the limiting rod, which is fixed to the base plate of the elastic shock absorbing mechanism by bolts.

[0016] In one of the embodiments of the present application, rubber pads are provided on both sides of the groove, and the rubber pads are fixed to the brush base by bolts.

[0017] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0018] 1. The brush of the power slip ring contact assembly forms multi-surface contact with the power slip ring through multiple inclined wear-resistant sheets, which greatly increases the contact area between the brush and the slip ring, making the contact more complete and meeting the stability requirements during current transmission;

[0019] 2. The bionic accordion scales coat wear-resistant sheet in the power slip ring contact assembly forms an effective lubricating layer on the friction interface, so that the contact surface obtains a good self-lubricating effect during operation, thereby significantly improving its wear resistance and extending the service life of the brush wear-resistant sheet;

[0020] 3. The slot mechanism in the power slip ring contact assembly can realize the convenient disassembly and replacement of the brush assembly without destroying the physical structure of the power slip ring device;

[0021] 4. The elastic damping mechanism in the power slip ring contact assembly can realize the self-adaptive adjustment function of the contact between the brush and the conductive slip ring, ensuring the stability and reliability of power transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The embodiment of the present application provides an electric slip ring contact assembly for a single point mooring system, which solves the problem of small contact area and insufficient contact between the brush and the slip ring in the prior art, and meets the stability requirements during current transmission.

[0035] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0036] Example:

[0037] like Figure 1-5 As shown, an electric slip ring contact assembly for a single point mooring system comprises a brush base 1, a brush 2, an elastic damping mechanism 3 and a slot mechanism 4.

[0038] One end of the brush base 1 is a connection end, and the other end is provided with a groove 11 for installation; rubber pads 12 are provided on both sides of the groove 11, and the rubber pads 12 are fixed on the brush base 1 by positioning bolts.

[0039] The brush 2 includes an elastic base spring 21 and a plurality of bionic accordion scale armor outer wear-resistant sheets 22; the surface of the bionic accordion scale armor outer wear-resistant sheet 22 is composed of a bionic wear-resistant surface organization and a lubricant, and the organization pattern is a geometric groove 11 array, and the lubricant is filled in the groove 11 array to form a wear-resistant bionic self-lubricating surface. The large surface of the bionic accordion scale armor outer wear-resistant sheet 22 is fitted onto the large surface of the middle slender support 23 of the elastic base spring 21, and then the exposed claws of the bionic accordion scale armor outer wear-resistant sheet 22 are bent inward, fitted to the opposite side of the large surface of the middle slender support 23, and clamped; the six middle slender supports 23 of the elastic base spring 21 embedded with the outer wear-resistant sheet 22 are bent in a certain direction and angle to tilt the slender supports 23.

[0040] The elastic damping mechanism 3 is installed in the groove 11. The elastic damping mechanism 3 includes a fixing bolt 31, a spring 32, a base plate 33 and a guide stopper 34. The base plate 33 is provided with a mounting hole. The guide stopper 34 is fixed on the base plate 33 by interference fit with the mounting hole. The fixing bolt 31 fixes the elastic damping mechanism 3 to the brush base 1 through the stopper hole of the guide stopper 34. The spring 32 is embedded in the guide stopper 34, one end of which is fixed to the stopper hole of the guide stopper 34, and the other end is fixed to the fixing bolt 31. The spring 32 in the elastic damping mechanism 3 is always kept in a stretched state. When the whole device is subjected to vibration impact or the brush 2 assembly is worn, the rebound of the spring 32 always ensures the close contact between the brush 2 and the power slip ring.

[0041] The slot mechanism 4 includes a slot base 41 and two limit rods 42. The slot base 41 is horizontally fixed on the base plate 33 of the elastic shock absorbing mechanism 3. The slot base 41 is provided with a slot for inserting the brush 2. The two limit rods 42 are respectively nested and installed on both sides of the slot base 41. A series of limit buckles 43 are provided on the limit rods 42, which play a fixing role on the brush 2 by cooperating with the limit slot provided on the elastic base spring leaf 21 in the brush 2.

[0042] The brush 2 can be detachably installed in the slot mechanism 4. When installing, the brush 2 is inserted obliquely into the slot base 41 and pressed to the position limited by the limit rod 42 for easy fixation. When disassembling, the limit rod 42 is pushed out, and the brush 2 pops out synchronously, and the brush 2 can be removed along the slot direction.

[0043] Optionally, the limiting rod 42 is provided with a limiting hole and is fixed to the base plate 33 of the elastic damping mechanism 3 by bolts. At this time, the brush 2 needs to be pressed during disassembly to disengage the limiting slot from the limiting buckle 43, and the brush 2 is pulled out tiltedly.

[0044] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0045] 1. The brush of the power slip ring contact assembly forms multi-surface contact with the power slip ring through multiple inclined wear-resistant sheets, which greatly increases the contact area between the brush and the slip ring, making the contact more complete and meeting the stability requirements during current transmission.

[0046] 2. The brush of the electric slip ring contact assembly takes the surface of accordion scales as the basic research model, introduces micron-level bionic tissue grooves on the contact surface of the brush wear-resistant sheet, and fills the lubricant into these grooves. When the two contact surfaces of the brush and the conductive slip ring are in relative friction, the lubricant is squeezed out from the bionic tissue grooves to form a uniform and lasting lubricating film, thereby forming an effective lubricating layer on the friction interface. In this way, the contact surface obtains a good self-lubricating effect during operation, thereby significantly improving its wear resistance and extending the service life of the brush wear-resistant sheet.

[0047] 3. Compared with the traditional slide groove design, the power slip ring contact assembly can realize the convenient disassembly and replacement of the brush without destroying the physical structure of the power slip ring device.

[0048] 4. The elastic shock-absorbing mechanism of the power slip ring contact assembly can realize the adaptive adjustment function of the contact between the brush and the conductive slip ring, avoiding the vibration impact of the equipment caused by the external environment or the excessive wear of the brush bionic scale armor wear-resistant sheet, which leads to the small contact area between the brush and the conductive slip ring, poor contact and even circuit breakage, thus ensuring the stable and reliable power transmission.

[0049] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
