Description

Technical Field

[0001] This invention relates to the field of hydro-generators, and in particular to a giant hydro-generator annular wind-driven carbon absorption device. Background Technology

[0002] During the operation of a giant hydro-generator unit, an excitation current is required. This is typically achieved by installing an excitation cable in a slip ring chamber located at the top of the unit. The excitation current is introduced into the bus ring plate through the cable. The generator slip ring is connected to the main shaft and rotates with the hydro-generator unit. Excitation carbon brushes, consisting of multiple positive and negative brushes, are arranged around the slip ring. Friction between the slip ring and the carbon brushes during rotation generates a small amount of carbon dust. If not cleaned promptly, this dust can cause a short circuit between the positive and negative poles of the excitation system. This could lead to a short circuit, fire, or other unit accidents.

[0003] The existing cleaning method involves arranging air intakes around the slip ring chamber and connecting them to a vacuum pump or fan via pipes. The toner is drawn into a filter by the airflow, achieving gas-solid separation. The collected toner is then cleaned periodically. However, this method requires the installation of air intake pipes, vacuum pumps, or filter devices, and the pipes need to cover the perimeter of the slip ring chamber. In the confined space of a hydroelectric generator room, this can easily cause spatial conflicts with other equipment, increasing installation difficulty and even forcing a reduction in equipment spacing, affecting subsequent operation and maintenance space, and resulting in high energy consumption and operating costs.

[0004] The excitation carbon brush and the unit slip ring use sliding contact to transmit current. Therefore, it is necessary to monitor and control the temperature of the slip ring and its contact part with the carbon brush. Currently, the temperature is measured manually on a regular basis. However, manual regular temperature measurement has poor real-time performance and is difficult to detect sudden high temperatures in time. At the same time, it increases the workload of operation and maintenance and safety risks. Summary of the Invention

[0005] This invention provides a giant hydro-generator annular wind-driven carbon suction device, which solves the problem that when a small amount of carbon powder is generated by the excitation carbon brush of a hydro-generator and sucked into a filter device through a vacuum pump or fan connected by a pipeline, it is easy to cause space conflicts with other equipment in the confined space of the hydro-generator room, increasing the difficulty of installation and resulting in higher energy consumption and operating costs. At the same time, the manual periodic measurement of slip ring temperature has poor real-time performance, increasing the workload of operation and maintenance and safety risks.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a giant hydro-generator annular wind-driven carbon absorption device, including a main shaft, a slip ring on the main shaft, a pad on the slip ring, a support on the outside of the main shaft, a wind-driven device between the support and the slip ring, a plurality of carbon absorption chambers on the wind-driven device, a plurality of support and limiting mechanisms on the support, and one end of the support and limiting mechanism abutting against the wind-driven device.

[0007] In the preferred embodiment, the main shaft is connected to the slip ring, which includes an upper slip ring and a lower slip ring. Multiple pads are provided between the upper slip ring and the lower slip ring. The upper slip ring and the lower slip ring are connected by multiple first bolts, which pass through the pads.

[0008] In the preferred embodiment, the pad is provided with fan-shaped blades, the pneumatic device is located between the upper slip ring and the lower slip ring, and the pneumatic device is provided with multiple infrared thermometers.

[0009] In the preferred embodiment, the bracket includes two support rings, with multiple guide bolts between the two support rings. The guide bolts are equipped with insulating sleeves and carbon brushes.

[0010] In the preferred embodiment, the pneumatic device has a ring structure, with an annular groove at the bottom. The carbon absorption chamber includes a wide channel located inside the pneumatic device, a narrow channel connected to the wide channel on one side, a vertical through groove on the carbon absorption chamber, and a carbon collection chamber on one side of the vertical through groove.

[0011] In the preferred embodiment, a filter plate is provided on one side of the carbon collection chamber, and the carbon absorption chamber includes two partitions with a narrow channel between them. The cross-section of the partitions is L-shaped.

[0012] In the preferred embodiment, the support limiting mechanism includes a support space, a speed limiting device, and a limiting mechanism. The support space is bolted to the guide column of the bracket, and the limiting mechanism abuts against the bottom of the pneumatic device.

[0013] In the preferred embodiment, the support includes a connecting plate, one end of which is provided with a clamp, which is bolted to the guide column, and the connecting plate is provided with a notch.

[0014] In a preferred embodiment, the limiting mechanism includes a support ring with a rotating ring abutting against the side of a ring groove. The support ring also has a guide wheel groove and a rotating frame. A guide wheel is mounted on the rotating frame and rests against the bottom of the ring groove.

[0015] In the preferred embodiment, the speed limiting device includes a bidirectional screw, two arc-shaped plates and two threaded seats. The bidirectional screw is connected to the two threaded seats. One end of the bidirectional screw is provided with a handle, and the arc-shaped plates are provided with brake pads. One end of the arc-shaped piece is rotatably connected to the threaded seat, and the other end of the arc-shaped piece is rotatably connected to the connecting plate. The threaded seat is mounted on the connecting plate.

[0016] The beneficial effects of this invention are as follows: When the generator is working, the upper slip ring and the lower slip ring rotate with the main shaft, and multiple pads on the slip ring rotate. The fan-shaped blades on the pads cause the wind-driven device to rotate. One end of the support and limiting mechanism is connected to the wind-driven device, and the other end supports the wind-driven device through a guide wheel. The wind-driven device rotates relative to the guide wheel. When the wind-driven device rotates, the rotating ring abuts against the ring groove and rotates, so that the support and limiting mechanism limits the wind-driven device.

[0017] When the pneumatic device rotates, air enters the narrow channel through the wide channel. According to Bernoulli's principle, as the air flows from the wide channel to the narrow channel, the cross-sectional area decreases, and the air velocity in the narrow channel increases. This creates a negative pressure at the outlet of the narrow channel, causing airflow at both ends of the vertical channel. This allows the air at the top and bottom of the vertical channel to enter the carbon collection chamber. As the space in the carbon collection chamber suddenly increases, the airflow speed slows down. Some of the toner will deposit and fall to the bottom of the carbon collection chamber, while the rest will pass through the filter plate with the airflow. The toner is blocked by the filter plate and enters the carbon collection chamber. After the filter plate filters the air, it is discharged, completing a complete toner collection process. This ensures that the toner in the upper and lower sliding rings is collected by the pneumatic device.

[0018] When the pneumatic device rotates, the infrared thermometer on the pneumatic device can measure the temperature of the upper and lower slip rings.

[0019] The support and limiting mechanism can support and limit the pneumatic device, so that the pneumatic device can rotate along a circular trajectory. By driving the bidirectional screw of the speed limiting device, the two arc-shaped plates open and close, and the two brake pads open and close, so as to control the contact between the brake pads and the side wall of the ring groove, thereby controlling the rotation speed of the pneumatic device, and thus controlling the air volume and temperature measurement speed of the carbon powder absorption at the vertical through groove. When carbon powder treatment is required in the pneumatic device or the pneumatic device needs to be stopped, the opening and closing angle of the brake pads is increased to stop the rotation of the pneumatic device.

[0020] The overall structure of the device is simple, utilizing the rotation of the main shaft to drive the pneumatic unit, saving energy and eliminating the need for excessive equipment around the support frame, thus saving space. It is suitable for generator rooms with limited space, avoiding the need for space-consuming components such as air intake ducts, vacuum pumps, or filters, which can cause space conflicts with other equipment, increase installation difficulty, and even force reduced equipment spacing, affecting subsequent maintenance and operation space and leading to higher energy consumption and operating costs. Simultaneously, the pneumatic unit can measure ambient temperature, avoiding the poor real-time performance of manual periodic temperature measurements, which can hinder the timely detection of sudden high temperatures and increase maintenance workload and safety risks, making it highly valuable for widespread adoption.

[0022] Example 1: like Figure 1-11 A giant hydro-generator annular wind-driven carbon absorption device includes a main shaft 1, a slip ring 4 on the main shaft 1, a pad 5 on the slip ring 4, a support 3 on the outer side of the main shaft 1, a wind-driven device 6 between the support 3 and the slip ring 4, multiple carbon absorption chambers 601 on the wind-driven device 6, and multiple support and limiting mechanisms 7 on the support 3, one end of the support and limiting mechanism 7 abutting against the wind-driven device 6. With this structure, the carbon brush 11 includes a positive carbon brush and a negative carbon brush. Conductive posts 202 are connected to the positive and negative conductors on both sides respectively. Multiple guide post bolts 302 on the support 3 are used; half of the guide post bolts 302 are connected to the positive carbon brush, and the other half are connected to the negative carbon brush. An insulating sleeve 303 is installed on one side of the carbon brush 11. The positive carbon brush is connected to the upper slip ring 401, and the negative carbon brush is connected to the lower slip ring 402. An insulating pad 5 is provided between the upper slip ring 401 and the lower slip ring 402.

[0023] When the generator is working, the upper slip ring 401 and the lower slip ring 402 rotate with the main shaft 1. Multiple pads 5 on the slip ring 4 rotate, and the fan-shaped blades 501 on the pads 5 cause the wind-driven device 6 to rotate. One end of the support and limiting mechanism 7 is connected to the wind-driven device 6, and the other end supports the wind-driven device 6 through the guide wheel 1004. The wind-driven device 6 rotates relative to the guide wheel 1004. When the wind-driven device 6 rotates, the rotating ring 1002 abuts against the ring groove 602 and rotates, so that the support and limiting mechanism 7 limits the wind-driven device 6.

[0024] When the pneumatic device 6 rotates, air enters the narrow channel 604 through the wide channel 603. According to Bernoulli's principle, the cross-sectional area of ​​the air decreases as it moves from the wide channel to the narrow channel, causing the air velocity in the narrow channel 604 to increase. This creates a negative pressure at the outlet of the narrow channel 604, resulting in airflow at both ends of the vertical channel 605. This allows the air at the top and bottom of the vertical channel 605 to enter the carbon collection chamber 606. As the space in the carbon collection chamber 606 suddenly increases, the airflow speed slows down. Some of the toner will deposit and fall to the bottom of the carbon collection chamber 606, while the rest will pass through the filter plate 607 with the airflow. The toner is blocked by the filter plate 607 and enters the carbon collection chamber 606. The filter plate 607 filters the airflow cleanly, completing a complete toner collection process, so that the toner in the upper slip ring 401 and lower slip ring 402 is collected by the pneumatic device 6.

[0025] When the pneumatic device 6 rotates, the infrared thermometer on the pneumatic device 6 can measure the temperature of the upper slip ring 401 and the lower slip ring 402.

[0026] The overall structure of the device is simple. It utilizes the rotation of the main shaft 1 to drive the fan-driven device 6, saving energy and eliminating the need for excessive equipment around the support frame 3, thus saving space. This makes it suitable for generator rooms with limited space, avoiding the need for existing layouts of air intake ducts, vacuum pumps, or filters that could cause spatial conflicts with other equipment, increase installation difficulty, or even force a reduction in equipment spacing, impacting subsequent maintenance and operation space and leading to higher energy consumption and operating costs. Simultaneously, the fan-driven device 6 can measure ambient temperature, avoiding the poor real-time performance of manual periodic temperature measurements, which can hinder the timely detection of sudden high temperatures and increase maintenance workload and safety risks.

[0027] The support and limiting mechanism 7 can support and limit the pneumatic device 6, so that the pneumatic device 6 can rotate along a circular trajectory. By driving the bidirectional screw 902 of the speed limiting device 9, the two arc-shaped plates 903 open and close, and the two brake plates 904 open and close, so as to control the contact between the brake plates 904 and the side wall of the annular groove 602, thereby controlling the rotation speed of the pneumatic device 6, and thus controlling the air volume and temperature measurement speed of the carbon powder absorbed at the vertical through groove 605. When carbon powder treatment is required in the pneumatic device 6 or the pneumatic device 6 needs to be stopped, the opening and closing angle of the brake plates 904 is increased so that the pneumatic device 6 stops rotating.

[0028] In a preferred embodiment, the main shaft 1 is connected to the slip ring 4. The slip ring 4 includes an upper slip ring 401 and a lower slip ring 402. Multiple pads 5 are provided between the upper slip ring 401 and the lower slip ring 402. The upper slip ring 401 and the lower slip ring 402 are connected by multiple first bolts 403, which pass through the pads 5. With this structure, when the generator is working, the upper slip ring 401 and the lower slip ring 402 rotate with the main shaft 1, and the multiple pads 5 on the slip ring 4 rotate. The fan-shaped blades 501 on the pads 5 cause the wind-driven device 6 to rotate. One end of the support and limiting mechanism 7 is connected to the wind-driven device 6, and the other end supports the wind-driven device 6 through a guide wheel 1004. The wind-driven device 6 rotates relative to the guide wheel 1004. When the wind-driven device 6 rotates, the rotating ring 1002 abuts against the ring groove 602 and rotates, so that the support and limiting mechanism 7 limits the wind-driven device 6.

[0029] In the preferred embodiment, the pad 5 is provided with a fan-shaped blade 501, and the fan-driven device 6 is located between the upper slip ring 401 and the lower slip ring 402. The fan-driven device 6 is provided with multiple infrared thermometers. With this structure, the fan-shaped structure of the fan-shaped blade 501 can increase the air volume, thereby providing greater rotational energy for the fan-driven device 6.

[0030] In a preferred embodiment, the support 3 includes two support rings 301, with multiple guide post bolts 302 between the two support rings 301. Insulating sleeves 303 are provided on the guide post bolts 302, and carbon brushes 11 are mounted on the guide post bolts 302. In this structure, the carbon brush 11 includes a positive carbon brush and a negative carbon brush. The conductive post 202 is connected to the positive and negative conductors on both sides, respectively. Half of the guide post bolts 302 on the support 3 are connected to the positive carbon brush, and the other half are connected to the negative carbon brush. The insulating sleeve 303 is installed on one side of the carbon brush 11. The positive carbon brush is connected to the upper sliding ring 401, and the negative carbon brush is connected to the lower sliding ring 402. An insulating pad 5 is provided between the upper sliding ring 401 and the lower sliding ring 402.

[0031] In the preferred embodiment, the pneumatic device 6 has an annular structure, with an annular groove 602 at the bottom. The carbon absorption chamber 601 includes a wide channel 603 located inside the pneumatic device 6, a narrow channel 604 connected to one side of the wide channel 603, a vertical through groove 605 on the carbon absorption chamber 601, and a carbon collection chamber 606 on one side of the vertical through groove 605. With this structure, when the pneumatic device 6 rotates, the air enters the narrow channel 604 through the wide channel 603. According to Bernoulli's principle, the cross-sectional area of ​​the air decreases as it moves from the wide channel to the narrow channel, and the air velocity in the narrow channel 604 increases. This creates a negative pressure at the outlet of the narrow channel 604, causing airflow at both ends of the vertical channel 605. This allows the air at the top and bottom of the vertical channel 605 to enter the carbon collection chamber 606. As the space in the carbon collection chamber 606 suddenly increases, the airflow speed slows down. Some of the toner will deposit and fall to the bottom of the carbon collection chamber 606, while the rest will pass through the filter plate 607 with the airflow. The toner is blocked by the filter plate 607 and enters the carbon collection chamber 606. The filter plate 607 filters the airflow cleanly, completing a complete toner collection process, so that the toner in the upper slip ring 401 and lower slip ring 402 is collected by the pneumatic device 6.

[0032] When the pneumatic device 6 rotates, the infrared thermometer on the pneumatic device 6 can measure the temperature of the upper slip ring 401 and the lower slip ring 402.

[0033] In the preferred embodiment, a filter plate 607 is provided on one side of the carbon collection chamber 606, and the carbon absorption chamber 601 includes two partitions 608, with a narrow channel 604 between the two partitions 608. The cross-section of the partitions 608 is L-shaped. With this structure, the filter plate 607 is connected to the pneumatic device 6 by a second bolt, so that the collected carbon powder can be processed by the operator later.

[0034] In the preferred embodiment, the support limiting mechanism 7 includes a support space 8, a speed limiting device 9, and a limiting mechanism 10. The support space 8 is connected to the guide column bolt 302 of the bracket 3, and the limiting mechanism 10 abuts against the bottom of the pneumatic device 6.

[0035] In the preferred embodiment, the support space 8 includes a connecting plate 802, one end of which is provided with a clamp 801. The clamp 801 is connected to the guide column bolt 302, and the connecting plate 802 has a notch 803. With this structure, the support limiting mechanism 7 can support and limit the pneumatic device 6, allowing the pneumatic device 6 to rotate along a circular trajectory. The clamp 801 is connected to the guide column bolt 302, facilitating the disassembly and installation of the support space 8 and the bracket 3. The notch 803 on the connecting plate 802 provides space for the rotating handle 9021, facilitating operator operation of the handle 9021 and preventing interference between the handle 9021 and the connecting plate 802.

[0036] In a preferred embodiment, the limiting mechanism 10 includes a support ring 1001, on which a rotating ring 1002 is provided. The rotating ring 1002 abuts against the side of the annular groove 602. The support ring 1001 has a guide wheel groove 1003 and a rotating frame. A guide wheel 1004 is provided on the rotating frame and abuts against the bottom of the annular groove 602. With this structure, the guide wheel groove 1003 provides space for the guide wheel 1004 to rotate, and the guide wheel 1004 abuts against the surface of the annular groove 602, so that the multiple support spaces 8 provide support for the pneumatic device 6.

[0037] In a preferred embodiment, the speed limiting device 9 includes a bidirectional screw 902, two arc-shaped plates 903 and two threaded seats 901. The bidirectional screw 902 is connected to the two threaded seats 901. One end of the bidirectional screw 902 is provided with a handle 9021, and the arc-shaped plates 903 are provided with brake pads 904. One end of the arc-shaped plate 903 is rotatably connected to the threaded seat 901, and the other end of the arc-shaped plate 903 is rotatably connected to the connecting plate 802. The threaded seat 901 is mounted on the connecting plate 802. With this structure, the bidirectional screw 902 of the speed limiting device 9 is driven to open and close the two arc-shaped plates 903, thereby opening and closing the two brake pads 904. This controls the contact between the brake pads 904 and the side wall of the annular groove 602, thereby controlling the rotation speed of the pneumatic device 6. This, in turn, controls the airflow and temperature measurement speed of the carbon powder absorbed at the vertical through groove 605. When carbon powder treatment is required in the pneumatic device 6 or when the pneumatic device 6 needs to be stopped, the opening and closing angle of the brake pads 904 is increased to stop the rotation of the pneumatic device 6.
