Description

Technical Field

[0001] This invention relates to the field of insulation technology between collector rings, specifically to an insulation device and collector ring system for insulation between collector rings. Background Technology

[0002] Slip rings, as key components in rotating electrical equipment that enable the transmission of electrical energy and signals between stationary and rotating parts, are widely used in wind turbine generators, cranes, cable reels, medical CT equipment, and industrial robots. During long-term high-speed rotation, slip rings are highly susceptible to inter-ring or ring-to-ground short circuits due to factors such as brush wear, carbon buildup, insulation aging, or humid environments. A short circuit can generate an inrush current hundreds of times greater than the rated current, accompanied by intense heating, electrical sparks, and even arcing. This can not only burn out the slip ring itself but also damage connected precision equipment such as frequency converters and motors, causing prolonged downtime and economic losses.

[0003] The existing Chinese patent with publication number CN120280242A includes an insulating post disposed between an upper ring and a lower ring. The insulating post is characterized in that: the insulating post has a segmented structure, the insulating post includes an upper insulating post and a lower insulating post, an intermediate insulating ring plate is disposed between the upper insulating post and the lower insulating post, the diameter of the upper insulating post is the same as the diameter of the lower insulating post, and the inner and outer sides of the intermediate insulating ring plate extend out of the lower insulating post.

[0004] When the above-mentioned device is in use, through multi-layer insulation design and mechanical coordination, it can effectively increase the creepage distance and achieve a significant improvement in insulation performance. However, in actual use, passively increasing the fixed insulation distance and the long-term rotation of the slip ring will cause carbon powder to accumulate and adhere to the insulation, which can easily lead to creepage and cause short circuit damage to the equipment. Therefore, it is difficult to automatically adjust the distance between the slip rings in the event of current fluctuation or short circuit.

[0005] Therefore, we propose an insulation device and a collector ring system for use between collector rings. Summary of the Invention

[0006] The purpose of this invention is to provide an insulation device and a collector ring system for use between collector rings, which has the advantage of automatically adjusting the distance between collector rings in the event of current fluctuations or short circuits, thus solving the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an insulation device and a collector ring system for use between collector rings, comprising a fixed base, on which a rotor wire driven by a power mechanism is rotatably connected and penetrates a fixed axis; a plurality of linearly arrayed collector ring bodies are movably fitted on the outer contour of the rotor wire, and the collector ring bodies are electrically connected to the rotor wire; each collector ring body has an insulating plate on both sides for insulating between the collector ring bodies, and the insulating plate is movably fitted on the outer contour of the rotor wire; a rubber ring is provided between every two adjacent insulating plates for adjusting the distance between the collector ring bodies, and the rubber ring is fitted on the outer contour of the rotor wire and movably connected; insulating posts are fixedly connected at symmetrical positions on both sides of the fixed base; a fixed plate is fixedly connected to the ends of two insulating posts; and an adjustment mechanism for automatically adjusting the distance between the collector ring bodies is provided on the fixed plate.

[0008] Preferably, each of the insulating posts has multiple brush holders movably connected to its outer contour, which are arranged corresponding to the slip ring body. Each of the brush holders has a brush body movably connected to its symmetrical sides, which is in contact with the surface of the slip ring body at the corresponding position.

[0009] Preferably, insulating tubes are symmetrically connected to both sides of the fixing plate, and multiple vent tubes corresponding to the rubber rings are symmetrically connected to the outer contours of the bottom ends of the two insulating tubes. The end of each vent tube away from the insulating tube is connected to the inner wall of the rubber ring at the corresponding position and fixedly connected.

[0010] Preferably, the adjusting mechanism includes an inner spline sleeve that is rotatably connected through a fixed plate, a spline shaft that is vertically and movably connected to the inner wall of the inner spline sleeve, a metal block that is fixedly connected to the bottom end of the spline shaft, and a reset spring that guides the metal block to reset and move is fixedly connected to the opposite surface of the inner spline sleeve and the top end of the spline shaft, and an electromagnet that attracts the metal block is fixedly connected to the top end of the rotor wire, and the coil of the electromagnet is connected in series with the rotor wire circuit.

[0011] Preferably, a support rod is rotatably connected to the outer contour of the top of the spline shaft, and piston rods for inflating the rubber ring are fixedly connected at symmetrical positions at both ends of the support rod. The bottom ends of the two piston rods respectively penetrate into the inner wall of the adjacent insulating tube and are movably connected.

[0012] Preferably, the fixed plate is provided with a cleaning mechanism for cleaning carbon powder on the insulating plate and the rubber ring. The cleaning mechanism includes a cleaning rod that is rotatably connected to the side of the fixed plate near the outer contour of the insulating plate and cleans the carbon powder on the surface of the insulating plate and the rubber ring. The outer contour of the cleaning rod is provided with a hard brush that contacts the surface of the insulating plate and the rubber ring. The top end of the cleaning rod is coaxially fixed to a first pulley.

[0013] Preferably, a second pulley is fixedly connected to the outer contour of the top of the inner spline sleeve, and a transmission belt for guiding the cleaning rod to clean the insulating plate and rubber ring is provided in the groove of the outer contour of the second pulley and the first pulley.

[0014] Preferably, the fixed plate is provided with an alarm mechanism for alarming the short circuit state of the rotor wire. The alarm mechanism includes a pressure sensor fixedly connected to the fixed plate, and the pressure sensor is connected to an external controller via a signal. A pressure spring for applying pressure to the pressure sensor is fixedly connected to the opposite surface of the pressure sensor and the support rod.

[0015] Preferably, it includes a brush assembly, an insulation gap adjustment assembly, a current detection module, an execution drive module, a gas drive module, a linkage cleaning module, a status monitoring and alarm module, and a rotating spindle, as well as multiple slip ring units coaxially sleeved on the rotating spindle and rotating with it; The brush assembly is fixedly disposed outside the slip ring unit and is used to slide electrical contact with the slip ring unit during rotation to transmit electrical energy or signals. An insulation gap adjustment assembly is disposed between adjacent slip ring units, including an elastic expansion body and a gas drive channel connected thereto; A current detection module is connected in series in the main circuit of the collector ring unit for real-time monitoring of the current status; The execution drive module is connected to the current detection module and generates mechanical displacement based on the detected abnormal current or short circuit signal; The gas-driven module, triggered by the execution drive module, injects or discharges gas into the elastic expansion body through the gas drive channel, thereby driving the elastic expansion body to expand or contract and automatically adjusting the physical distance between adjacent collector ring units. The linkage cleaning module is connected to the execution drive module. While the execution drive module is in operation, it drives the cleaning element to clean the surface of the insulation gap adjustment component with carbon powder. The status monitoring and alarm module is set on the motion path of the execution drive module to monitor its displacement and generate a remote alarm signal when the displacement exceeds the short circuit threshold.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When a short circuit or abnormal current fluctuation occurs in the rotor conductor circuit, the electromagnetic force generated by the electromagnet connected in series in the circuit increases sharply, overcoming the elastic potential energy of the reset spring and attracting the metal block to move downward. The metal block drives the support rod and piston rod to move synchronously through the spline shaft, forcing the air in the insulating tube into each rubber ring through the vent pipe. This causes the rubber ring to expand and push the insulating plate between adjacent slip ring bodies to unfold outward, thereby automatically increasing the physical distance and creepage distance between the rings. When the current returns to normal, the reset spring pushes the metal block to reset, and the rubber ring contracts, restoring the slip ring bodies to the normal spacing. This achieves real-time linkage adjustment between the distance between slip ring bodies and the current state, avoiding creepage and short circuit problems caused by carbon powder accumulation or overvoltage, and significantly improving the insulation reliability and self-adaptive capability of the slip ring system.

[0017] 2. When the electromagnet attracts the metal block, the rotor wire can synchronously drive the spline shaft to rotate, and the spline shaft drives the inner spline sleeve to rotate, so that the second pulley at the top of the inner spline sleeve drives the first pulley and the cleaning rod to rotate synchronously through the transmission belt. The outer contour of the cleaning rod is equipped with a hard brush that contacts the surface of the insulating plate and the rubber ring. During the rotation, it can effectively remove the conductive carbon powder attached to the surface of the insulating plate and the rubber ring. This cleaning mechanism is linked with the adjustment mechanism. When the distance between the rings is adjusted to the limit position, the cleaning is automatically started. No additional power source is required. This ensures the timeliness of cleaning and avoids the conductive path formed by the long-term accumulation of carbon powder, reduces the risk of creepage caused by carbon bridge formation, and extends the maintenance cycle of the slip ring body.

[0018] 3. When the electromagnet attracts the metal block, causing the support rod to move downward, the support rod compresses the pressure spring. The pressure spring transmits the pressure to the pressure sensor. When a short circuit fault occurs and the rubber ring expands to its limit, the support rod moves downward to its maximum extent. The pressure value of the pressure spring on the pressure sensor exceeds the set threshold. The pressure sensor converts the pressure data into an electrical signal and transmits it remotely to the external controller, triggering an alarm. This allows the rubber ring to respond automatically while simultaneously sending a clear short circuit fault signal to maintenance personnel, facilitating timely problem location and maintenance scheduling. This effectively shortens the fault response time and reduces the risk of equipment damage.

[0019] The use of the above structures solves the problem that in the actual use of existing devices, the passive increase in fixed insulation distance and the accumulation of carbon powder on the insulation due to the long-term rotation of the slip rings can easily lead to creepage and short circuit damage to the equipment. Therefore, it is difficult to automatically adjust the distance between the slip rings in the event of current fluctuations or short circuits. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0023] Please see Figures 1 to 9This invention provides a technical solution: an insulation device and a collector ring system for inter-collector rings, comprising a fixed base 1, on which a rotor wire 2 driven by a power mechanism is rotatably connected and penetrated by a fixed axis. Multiple linear arrays of collector ring bodies 3 are movably fitted onto the outer contour of the rotor wire 2, and the collector ring bodies 3 are electrically connected to the rotor wire 2. Each collector ring body 3 has an insulating plate 4 on both sides to insulate between the collector ring bodies 3, and the insulating plate 4 is movably fitted onto the outer contour of the rotor wire 2. Between each pair of adjacent insulating plates 4, a rubber ring 5 is provided to adjust the distance between the collector ring bodies 3, and the rubber ring 5 is fitted onto the outer contour of the rotor wire 2 and movably connected. Insulating posts 7 are fixedly connected at symmetrical positions on both sides of the fixed base 1, and a fixed plate 17 is fixedly connected to the ends of the two insulating posts 7. The fixed plate 17 is provided with an adjustment mechanism for automatically adjusting the distance between the collector ring bodies 3.

[0024] Each of the insulating posts 7 has multiple brush holders 8 movably connected to its outer contour, which are arranged corresponding to the slip ring body 3. Each of the brush holders 8 has a brush body 9 movably connected to its two sides at symmetrical positions, which are in contact with the surface of the slip ring body 3 at the corresponding positions.

[0025] In use, by setting a fixed base 1, and the rotor wire 2 set on the fixed base 1, the rotor wire 2 can be rotatably connected on the fixed base 1. The above-mentioned power mechanism is a motor after being energized, and the output shaft of the motor is coaxially fixed to the rotor wire 2. When the motor is started, the motor can drive the rotor wire 2 to rotate on the fixed base 1. The slip ring body 3 set on the rotor wire 2, and the insulating plate 4 set on the slip ring body 3, can prevent creepage short circuit between two adjacent slip ring bodies 3. The insulating post 7 provided on the base 1, and the fixing plate 17 provided on the insulating post 7, can fix the fixing plate 17 on the top of the rotor wire 2. The brush holder 8 provided on the insulating post 7, and the brush holder 8 is movably sleeved on the outer contour of the insulating post 7, can move up and down on the outer contour of the insulating post 7. The brush body 9 provided on the brush holder 8 can push the brush body 9 to fit against the surface of the collector ring body 3 with the spring plate on the brush holder 8, so that the brush body 9 can transmit current to the surface of the rotating collector ring body 3.

[0026] The rubber ring 5 is installed on the rotor wire 2 and is located between two adjacent insulating plates 4. The rubber ring 5 can be movably connected on the outer contour of the rotor wire 2. The adjustment mechanism installed on the fixed plate 17 can automatically adjust the distance between the collector ring bodies 3 when the current fluctuates or short circuit occurs on the collector ring body 3, so as to avoid the problem of creepage short circuit caused by carbon powder accumulating on the insulating plates 4 and rubber ring 5 between the collector ring bodies 3. Example 2:

[0027] Building upon Example 1, the following is a further step: Insulating tubes 10 are symmetrically connected to both sides of the fixing plate 17. Multiple venting tubes 6, which are arranged corresponding to the rubber rings 5, are pierced and fixedly connected to the outer contour of the bottom end of the two insulating tubes 10. The end of each venting tube 6 away from the insulating tube 10 is respectively connected to the inner wall of the rubber ring 5 at the corresponding position.

[0028] The adjustment mechanism includes an inner spline sleeve 14 that is rotatably connected to a fixed plate 17. A spline shaft 13 is movably connected to the inner wall of the inner spline sleeve 14. A metal block 15 is fixedly connected to the bottom end of the spline shaft 13. A reset spring 24 is fixedly connected to the opposite surface of the inner spline sleeve 14 and the top end of the spline shaft 13 to guide the metal block 15 to reset. An electromagnet 16 is fixedly connected to the top end of the rotor wire 2 to attract the metal block 15. The coil of the electromagnet 16 is connected in series with the rotor wire 2 circuit.

[0029] A support rod 12 is rotatably connected to the outer contour of the top end of the spline shaft 13. Piston rods 11 for inflating the rubber ring 5 are fixedly connected to both ends of the support rod 12 at symmetrical positions. The bottom ends of the two piston rods 11 are respectively connected to the inner wall of the adjacent insulating tube 10.

[0030] In use, the insulating tube 10 provided on the fixing plate 17 is used to fix and support the fixing plate 17. The vent pipe 6 provided on the insulating tube 10 allows the rubber ring 5 to communicate with the inner wall of the insulating tube 10. The inner spline sleeve 14 provided on the fixing plate 17 allows for rotatable connection. The spline shaft 13 provided on the inner spline sleeve 14, with the inner spline sleeve 14 fitted onto the outer contour of the spline shaft 13, allows the spline shaft 13 to move up and down within the inner wall of the inner spline sleeve 14. A metal block 15 is provided on the key shaft 13, which is fixedly supported at the bottom end of the spline shaft 13. The return spring 24 provided on the spline shaft 13 and the inner spline sleeve 14 can support the position of the metal block 15 under its own elastic potential energy. The support rod 12 provided on the spline shaft 13 can be rotatably connected on the outer contour of the spline shaft 13. The piston rod 11 provided on the support rod 12 is fixedly supported on the support rod 12. At the same time, the piston rod 11 passes through the inner wall of the insulating tube 10 and is connected for lifting and lowering movement.

[0031] In actual use, the electromagnet 16 installed on the rotor wire 2, with its coil connected in series with the rotor wire 2 circuit, generates a constant electromagnetic force in the electromagnet 16 under normal conditions when a normal current flows through its coil. This electromagnetic force is less than the elastic potential energy of the return spring 24, so the electromagnet 16 is separated from the metal block 15. When the current fluctuates, and the electromagnetic force on the electromagnet 16 increases and exceeds the elastic potential energy of the return spring 24, the electromagnet 16 attracts the metal block 15. The spline shaft 13 moves downward, and under the action of the metal block 15, it can simultaneously drive the support rod 12 and the piston rod 11 to move downward. This allows the spline shaft 13 to squeeze the return spring 24, and the piston rod 11 to fit against the inner wall of the insulating tube 10. Thus, the piston rod 11 can push the air inside the insulating tube 10 through the vent pipe 6 to the inner wall of the rubber ring 5, causing the rubber ring 5 to expand and push the two adjacent collector ring bodies 3 to unfold, increasing the distance between the collector ring bodies 3 and avoiding creepage between the collector ring bodies 3, which could lead to a short circuit.

[0032] When a short circuit occurs, the electromagnetic force on the electromagnet 16 increases sharply, which in turn allows the electromagnet 16 to attract the metal block 15 to move down quickly and be attracted, so that the rubber ring 5 can expand to its limit, further increasing the spacing between the slip ring bodies 3, and avoiding the problem of creepage short circuit caused by carbon powder accumulation, which could damage the equipment.

[0033] When the current returns to normal and the electromagnet 16 returns to a constant electromagnetic force, the electromagnetic force is less than the elastic potential energy of the return spring 24. This causes the return spring 24 to push the spline shaft 13 and the metal block 15 to move upwards to reset. The above structures then move in the opposite direction to reset, causing the rubber ring 5 to contract and restore the slip ring body 3 to its normal spacing. This achieves real-time linkage adjustment between the distance between the slip ring bodies 3 and the current state, avoiding creepage and short circuit problems caused by carbon powder accumulation or overvoltage. It significantly improves the insulation reliability and self-adaptive capability of the slip ring system. Example 3:

[0034] Building upon Example 2, the following is a further step: The fixed plate 17 is provided with a cleaning mechanism for cleaning carbon powder on the insulating plate 4 and the rubber ring 5. The cleaning mechanism includes a cleaning rod 18 that is rotatably connected to the side of the fixed plate 17 near the outer contour of the insulating plate 4, and is used to clean carbon powder on the surface of the insulating plate 4 and the rubber ring 5. The outer contour of the cleaning rod 18 is provided with a hard brush that contacts the surface of the insulating plate 4 and the rubber ring 5. The top end of the cleaning rod 18 is coaxially fixed to a first pulley 19.

[0035] A second pulley 20 is fixedly connected to the outer contour of the top end of the inner spline sleeve 14. The second pulley 20 and the groove of the outer contour of the first pulley 19 are equipped with a transmission belt 21 for cleaning the insulating plate 4 and the rubber ring 5 by a guide cleaning rod 18.

[0036] In use, the cleaning rod 18 provided on the fixed plate 17 can be rotated on the fixed plate 17. The first pulley 19 provided on the cleaning rod 18 can be coaxially fixedly connected to the cleaning rod 18. The second pulley 20 provided on the inner spline sleeve 14 is fixedly supported on the outer contour of the inner spline sleeve 14. The transmission belt 21 provided on the second pulley 20 and the first pulley 19, and the transmission belt 21 is sleeved in the groove of the outer contour of the first pulley 19 and the second pulley 20, so that the transmission belt 21 can be connected to the first pulley 19 and the second pulley 20 for transmission.

[0037] In actual use, when the electromagnet 16 attracts the metal block 15, the rotor wire 2 can synchronously drive the spline shaft 13 to rotate, and the inner spline sleeve 14 can drive the second pulley 20 to rotate synchronously under the action of the spline shaft 13. Thus, the transmission belt 21 can drive the cleaning rod 18 to rotate on the fixed plate 17 through the first pulley 19 under the action of the second pulley 20. The cleaning rod 18 is equipped with a hard brush that contacts the surface of the insulating plate 4 and the rubber ring 5. Thus, the rotation of the cleaning rod 18 can clean the carbon powder on the surface of the insulating plate 4 and the rubber ring 5, reducing the risk of creepage caused by carbon bridge formation and extending the maintenance cycle of the collector ring body 3. Example 4:

[0038] Building upon Example 3, the following is a further step: The fixed plate 17 is provided with an alarm mechanism for alarming the short circuit state of the rotor wire 2. The alarm mechanism includes a pressure sensor 22 fixedly connected to the fixed plate 17, and the pressure sensor 22 is connected to an external controller via a signal. A pressure spring 23 is fixedly connected to the opposite surface of the pressure sensor 22 and the support rod 12 to apply pressure to the pressure sensor 22.

[0039] In use, the pressure sensor 22 is fixedly supported on the fixed plate 17. The pressure sensor 22 is equipped with a pressure spring 23. When the electromagnet 16 attracts the metal block 15, the spline shaft 13 drives the support rod 12 to move downwards, and the support rod 12 compresses the pressure spring 23. This allows the pressure spring 23 to apply pressure to the pressure sensor 22 under its own elastic force. The pressure sensor 22 is connected to an external controller via a signal connection, enabling it to convert the detected pressure data into an electrical signal and transmit it remotely. When the electromagnet 16 attracts the metal block 15 to the external controller, the pressure applied by the pressure spring 23 to the pressure sensor 22 exceeds the set threshold. As a result, the external controller can issue an alarm to the staff. At the same time as the rubber ring 5 responds automatically, it can send a clear short-circuit fault signal to the maintenance personnel, which facilitates timely location of the problem and arrangement of maintenance. This effectively shortens the fault response time and reduces the risk of equipment damage. The fact that the pressure sensor 22 can convert the detected pressure data into an electrical signal and remotely transmit it to the external controller is a well-known prior art and will not be described in detail here.

[0040] The slip ring system includes a brush assembly, an insulation gap adjustment assembly, a current detection module, an execution drive module, a gas drive module, a linkage cleaning module, a status monitoring and alarm module, and a rotating spindle, as well as multiple slip ring units coaxially mounted on the rotating spindle and rotating with it; The brush assembly is fixedly disposed outside the slip ring unit and is used to slide electrical contact with the slip ring unit during rotation to transmit electrical energy or signals. An insulation gap adjustment assembly is disposed between adjacent slip ring units, including an elastic expansion body and a gas drive channel connected thereto; A current detection module is connected in series in the main circuit of the collector ring unit for real-time monitoring of the current status; The execution drive module is connected to the current detection module and generates mechanical displacement based on the detected abnormal current or short circuit signal; The gas-driven module, triggered by the execution drive module, injects or discharges gas into the elastic expansion body through the gas drive channel, thereby driving the elastic expansion body to expand or contract and automatically adjusting the physical distance between adjacent collector ring units. The linkage cleaning module is connected to the execution drive module. While the execution drive module is in operation, it drives the cleaning element to clean the surface of the insulation gap adjustment component with carbon powder. The status monitoring and alarm module is set on the motion path of the execution drive module to monitor its displacement and generate a remote alarm signal when the displacement exceeds the short circuit threshold.

[0041] Furthermore, the existing device can automatically adjust the distance between the collector rings in the event of current fluctuations or short circuits, making it convenient to use and superior to traditional products.

[0042] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

The alarm mechanism includes a pressure sensor (22) fixedly connected to the fixed plate (17), and the pressure sensor (22) is connected to an external controller via a signal. A pressure spring (23) is fixedly connected to the opposite surface of the pressure sensor (22) and the support rod (12) to apply pressure to the pressure sensor (22).

9. A slip ring system, applied to an insulation device for inter-slip rings as described in any one of claims 1-8, characterized in that: It includes a brush assembly, an insulation gap adjustment assembly, a current detection module, an execution drive module, a gas drive module, a linkage cleaning module, a status monitoring and alarm module, and a rotating spindle, as well as multiple slip ring units coaxially mounted on the rotating spindle and rotating with it; The brush assembly is fixedly disposed outside the slip ring unit and is used to slide electrical contact with the slip ring unit during rotation to transmit electrical energy or signals. An insulation gap adjustment assembly is disposed between adjacent slip ring units, including an elastic expansion body and a gas drive channel connected thereto; A current detection module is connected in series in the main circuit of the collector ring unit for real-time monitoring of the current status; The execution drive module is connected to the current detection module and generates mechanical displacement based on the detected abnormal current or short circuit signal; The gas-driven module, triggered by the execution drive module, injects or discharges gas into the elastic expansion body through the gas drive channel, thereby driving the elastic expansion body to expand or contract and automatically adjusting the physical distance between adjacent collector ring units. The linkage cleaning module is connected to the execution drive module. While the execution drive module is in operation, it drives the cleaning element to clean the surface of the insulation gap adjustment component with carbon powder. The status monitoring and alarm module is set on the motion path of the execution drive module to monitor its displacement and generate a remote alarm signal when the displacement exceeds the short circuit threshold.
