Description

Technical Field

[0001] This invention relates to the field of generator rotor backflushing technology, and in particular to a Russian-made generator rotor cooling water backflushing tool. Background Technology

[0002] During operation, the rotor and internal components of a generator gradually accumulate carbon deposits, grease, and other dirt. This dirt not only reduces the generator's heat exchange efficiency but also affects its heat dissipation performance, leading to excessively high generator temperatures. Backflushing can effectively clean this dirt and restore the generator to a clean and unobstructed state.

[0003] For the existing TBM160-2 generator, the rotor cooling water enters from the center hole of the generator rotor shaft and enters the top coil of the rotor through 8 branches. It then enters the return water pipe inside the shaft from the coil on the side of the shaft. This is the working state of the generator cooling water. During maintenance, it is necessary to backwash these branch cooling water pipes with reverse water. The specific process is as follows: disassemble these 16 branch joints, backwash them one by one in groups, block all other branches that do not need to be involved, and so on, until all are flushed. The workload is huge and it is easy to cause secondary defects. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0029] Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a backflushing tool for the rotor cooling water of a Russian-made generator 301b. It includes a sealing assembly 100, comprising a mounting member 101 for collecting and discharging wastewater after backflushing the rotor branch, and a spring member 102 mounted on the mounting member 101 for connecting to the branch to be backflushed, and a sealing member 103 mounted on the spring member 102, which, driven by the spring member 102, seals the branch being backflushed; and an opening / closing assembly 200, including a driving member 201 mounted on the mounting member 101, which is a rotating member 2. 02 provides driving force, and the rotating member 202 disposed on the elastic member 102 is used to drive the opening and closing member 203 to perform opening and closing movements, and the opening and closing member 203 disposed on the rotating member 202 performs opening and closing to block the mounting member 101; and the displacement assembly 300 includes the rotating member 301 disposed on the mounting member 101 to provide driving force to the connecting member 302, the connecting member 302 disposed on the rotating member 301 is driven to rotate, and the walking member 303 disposed on the connecting member 302 is driven by the connecting member 302 to perform alternating walking movements, pushing the overall device to move.

[0031] Specifically, the mounting component 101 includes a housing 101a and an outlet 101b opened on the side of the housing 101a. The housing 101a is hollow and is used to collect wastewater after backwashing and discharge it through the outlet 101b.

[0032] Furthermore, the elastic element 102 includes a drain cylinder 102a fixedly connected to the housing 101a, a circular groove 102b formed on the drain cylinder 102a, a first spring 102c fixedly connected in the circular groove 102b, and a connecting cylinder 102d fixedly connected to the end of the first spring 102c. The drain pipe is used to receive the connecting cylinder 102d. The connecting cylinder 102d is slidably connected in the circular groove 102b. The circular groove 102b provides guidance for the connecting cylinder 102d. The first spring 102c provides thrust for the connecting cylinder 102d. Multiple first springs 102c are provided and are evenly distributed around the circumference.

[0033] Furthermore, the seal 103 includes an opening 103a formed on the housing 101a, and a rubber sheet 103b fixedly connected in the opening 103a. The opening 103a is used to accommodate the rubber sheet 103b, and the inner ring of the rubber sheet 103b is fixedly connected to the side of the connecting cylinder 102d.

[0034] Operation process: When the housing 101a passes through the rotor central shaft, due to the compression of the inner wall of the rotor central shaft, the connecting cylinder 102d moves downward due to the compression of its inclined end. The first spring 102c contracts. When it is aligned with the innermost branch, under the thrust of the first spring 102c, the connecting cylinder 102d extends and inserts into the branch to be drained, and drives the rubber sheet 103b to move upward to seal the branch. Backwash water is injected through the inlet. Under the action of the housing 101a, the remaining branches are completely blocked. The branch to be drained collects and discharges the backwashed sewage through the housing 101a, effectively saving operation time and improving work efficiency.

[0035] Example 2

[0036] Reference Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the driving component 201 includes a motor 201a fixedly connected in the housing 101a and a gear 201b fixedly connected to the output end of the motor 201a. The motor 201a provides driving force to the gear 201b, and the gear 201b drives the rotating component 202 to rotate.

[0037] Specifically, the rotating component 202 consists of a fixed block 202a fixedly connected to the drain cylinder 102a, a hole 202b opened in the fixed block 202a, a rotating ring 202c rotatably connected to the fixed block 202a, a groove 202d opened in the rotating ring 202c, a first rack 202e fixedly connected to the rotating ring 202c, and a second rack 202f fixedly connected to the rotating ring 202c. The fixed block 202a is used to receive the rotating ring 202c. The sewage after backwashing enters the housing 101a through the hole 202b. The rotating ring 202c is used to drive the opening and closing component 203 to rotate. The groove 202d is used to connect with the opening and closing component 203. Multiple first racks 202e are provided and are evenly distributed in a circle. The second rack 202f meshes with the gear 201b.

[0038] Furthermore, the opening and closing component 203 includes an opening and closing plate 203a rotatably connected to the fixed block 202a, and a toothed groove 203b formed on the opening and closing plate 203a. The opening and closing plate 203a is used to seal the hole 202b. The first rack 202e is engaged in the toothed groove 203b. Multiple opening and closing plates 203a and toothed grooves 203b are provided and are evenly distributed in a circumference. The number of opening and closing plates 203a and toothed grooves 203b corresponds to the number of first racks 202e.

[0039] The rest of the structure is the same as in Example 1.

[0040] Operation process: When backwashing is completed on one of the rotor's branches, motor 201a starts, driving gear 201b to rotate. Since gear 201b meshes with the second rack 202f, gear 201b drives the rotating ring 202c to rotate on the fixed block 202a. The rotating ring 202c, through the first rack 202e fixedly connected to it, drives multiple opening and closing plates 203a rotatably connected to the fixed block 202a to rotate, sealing the hole 202b. At this time, the whole unit can move to prevent gaps from forming between the discharge branch and the device when the device is displaced to guide the sewage discharge of other branches, which would cause water leakage. When the next branch to be backwashed is reached, the motor 201a rotates in the opposite direction, and multiple opening and closing plates 203a open and slide in the slot 202d, removing the seal on the hole 202b, so that the backwashed sewage can be discharged into the housing 101a.

[0041] Example 3

[0042] Reference Figures 1-6This is the third embodiment of the present invention. The difference between this embodiment and the previous embodiments is that the rotating component 301 includes a placement plate 301a fixedly connected to the side of the housing 101a, a motor 301b fixedly connected to the placement plate 301a, and a first bevel gear 301c fixedly connected to the output end of the motor 301b. The placement plate 301a is used to provide driving force to the motor 301b, the motor 301b provides driving force to the first bevel gear 301c, and the first bevel gear 301c is used to drive the connecting component 302 to run.

[0043] Specifically, the connector 302 includes a vertical plate 302a fixedly connected to the placement plate 301a, a rotating shaft 302b rotatably connected to the vertical plate 302a, and a second bevel gear 302c fixedly connected to the rotating shaft 302b. The vertical plate 302a provides support for the rotating shaft 302b, which drives the traveling member 303 to run. The second bevel gear 302c meshes with the first bevel gear 301c.

[0044] Furthermore, the traveling component 303 includes a connecting shaft 303a fixedly connected to the rotating shaft 302b, a lower support rod 303b rotatably connected to the connecting shaft 303a, a second spring 303c fixedly connected to the lower support rod 303b, and an upper support rod 303d slidably connected to the lower support rod 303b. The connecting shaft 303a is located on the side of the rotating shaft 302b, and there are two connecting shafts 303a, which are respectively located at the upper and lower ends on both sides of the rotating shaft 302b. At this location, the lower support rod 303b is fixedly connected to the connecting shaft 303a. The lower support rod 303b is hollow. The second spring 303c provides elastic force to the lower support rod 303b and the upper support rod 303d. The upper support rod 303d is fixedly connected to the end of the second spring 303c. The ends of the lower support rod 303b and the upper support rod 303d are both made of rubber. There are two lower support rods 303b, two second springs 303c, and two upper support rods 303d, which are arranged symmetrically.

[0045] The rest of the structure is the same as in Example 2.

[0046] Operation process: After the backwashing of one branch of the rotor is completed, the opening and closing part 203 is closed, the motor 301b is started, which drives the first bevel gear 301c fixedly connected to the output end of the motor 301b to rotate. The first bevel gear 301c drives the second bevel gear 302c to rotate, and the rotating shaft 302b rotates accordingly. The rotating shaft 302b drives the two connecting shafts 303a to rotate eccentrically. The connecting shafts 303a drive the two sets of lower support rods 303b and upper support rods 303d to move alternately. Under the thrust of the second spring 303c, the lower support rods 303b and upper support rods 303d are pressed against the inner wall of the rotor central shaft, pushing the entire device to move in the rotor central shaft and align with the branch to which the backwashed sewage needs to be discharged.
