Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic machinery, in particular to a hydraulic machinery paddle adjuster using high-pressure pure water as operating medium. BACKGROUND

[0002] Traditional Kaplan turbine often has the problem of paddle operating oil leakage. These hydraulic oils usually enter the sump or hub and are directly discharged into the environment without treatment, causing pollution. In order to protect the water environment and reduce operation and maintenance costs, many domestic and foreign hydropower stations and water pumping stations are gradually carrying out oil reduction and oil-free transformation, such as using water instead of operating oil for paddle hydraulic operation, which can not only avoid environmental pollution and reduce the cost of supply, but also greatly benefit the working environment and safety risk of mechanical and electrical equipment installation and operation and maintenance personnel as water is a clean medium.

[0003] Currently, in the prior art, oxygen-free water is used to replace operating oil for paddle hydraulic operation, for example, the applicant's early patent application CN201910746163.7 discloses a hydraulic turbine paddle adjuster using oxygen-free water as operating medium, from which it can be seen that oxygen-free water is more environmentally friendly in terms of operating medium.

[0004] In addition, the applicant found in subsequent production practice that although the use of oxygen-free water to replace operating oil for paddle hydraulic operation can avoid environmental pollution, there are still certain technical problems in the scheme of "oxygen-free water replacing operating oil", for example: the manufacturing cost of oxygen-free water is relatively high, and in the operation process of the hydraulic turbine, considering the problems of oxygen-free water manufacturing and continuous supply, additional oxygen removal equipment is often needed to remove dissolved oxygen in the water, which not only increases the complexity of the structure of the related equipment, but also increases the cost of putting into production and the operation cost of the hydraulic turbine. In addition, once the oxygen removal equipment fails or the seal fails, the oxidation of metal components still exists to some extent during operation, especially during gap operation, which can easily cause the connection between the rotating joint and the oxygen-free water pipeline to be blocked, which can easily cause the equipment to be stuck or damaged, the pipeline to be torn and broken, etc., so that the hydraulic turbine cannot operate normally, and even structural damage occurs, which undoubtedly reduces the reliability of the equipment operation.

DETAILED DESCRIPTION

[0025] The inventive concepts of the present disclosure will be described below using terms that the person skilled in the art usually uses to convey the substance of their work to other skilled persons in the art. However, these inventive concepts can be embodied in many different forms, and therefore should not be considered limited to the embodiments described herein.

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Meanwhile, the paddle adjuster in the present application can be applied to hydraulic machinery, such as water turbines, water pumps and other hydraulic machinery. In order to facilitate the introduction, the structure and operation of the paddle adjuster proposed in the present application are introduced in combination with the structure of a conventional water turbine. However, it should be pointed out that the paddle adjuster in the present application is not limited to application in water turbines.

[0027] The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] The paddle adjuster of the hydraulic machinery equipment in the prior art uses oxygen-free water to replace operating oil for paddle hydraulic operation, so as to avoid environmental pollution that may be caused by operating oil. However, the scheme of “oxygen-free water replacing operating oil” has found certain technical problems in actual production practice, such as cost problem, equipment operation reliability problem, and equipment structure complexity problem.

[0029] Therefore, in order to solve the related technical problems existing in the scheme of "oxygen-free water replacing operating oil", the existing paddle adjuster and its operating medium are improved, and a hydraulic mechanical paddle adjuster using high-pressure pure water as operating medium is provided, as shown in the accompanying drawings Figures 1-2 The hydraulic mechanical paddle adjuster includes a high-pressure pure water system, an anti-blocking system and an adjusting system. The high-pressure pure water system is connected with the adjusting system through the anti-blocking system. On one hand, the high-pressure pure water is used as operating medium to be delivered to the adjusting system to drive the related components in the adjusting system to run, so as to achieve the purpose of adjusting the paddle. On the other hand, considering that the high-pressure pure water may cause oxidation of metal components, the anti-blocking system is arranged to connect the high-pressure pure water system with the adjusting system, so that the related components in the adjusting system will not be blocked when rotating at the connection between the adjusting system and the high-pressure pure water system, avoiding the paddle adjuster from being stuck or damaged, the pipeline from being torn and broken, etc., ensuring the normal operation of the hydraulic machine and improving the reliability of the operation of the related hydraulic machine equipment.

[0030] For the high-pressure pure water system, a speed regulator 14 and a water tank 15 are arranged. The water tank 15 is provided with a first high-pressure water pipe 16a and a second high-pressure water pipe 16b. The first high-pressure water pipe 16a and the second high-pressure water pipe 16b are connected with the anti-blocking system and are in communication with the water passage in the adjusting system through the anti-blocking system, for providing high-pressure pure water medium to the adjusting system or recovering the pure water medium. The first high-pressure water pipe 16a and the second high-pressure water pipe 16b are in a one-in-one-out relationship. That is, the first high-pressure water pipe 16a can be used as a water outlet pipe or a water return pipe, and the second high-pressure water pipe 16b can be used as a water return pipe or a water outlet pipe. This can be adjusted according to the actual paddle adjustment requirement by arranging corresponding adjusting valves in the water tank 15. On the basis of conventional valve control technology, the speed regulator 14 is a conventional speed regulating device, so that the pure water medium can be delivered to the adjusting system at a high pressure.

[0031] As a preferred embodiment, the pure water delivered by the high-pressure pure water system to the adjusting system has a water pressure of 10-16 MPa. On one hand, the increase of the water pressure is beneficial to reducing the volume, mass and material of the related components in the adjusting system. In specific production practice, under this water pressure, the mass of the water receiver 1 in the adjusting system can be controlled within 30 kg, the mass of the servomotor 2 in the adjusting system can be controlled within 800 kg, and the material cost of the equipment can be controlled within 30,000 RMB. On the other hand, due to the increase of the water pressure, the volume of the related components in the adjusting system is reduced, and the water consumption is also greatly reduced. At the same time, with the recycling of the pure water, only the loss of some naturally seeped water needs to be supplemented during the normal operation of the equipment, so the amount of pure water used is reduced.

[0032] In addition, from the perspective of operating medium, the application replaces the operating oil with pure water, and the pure water is the conventional industrial pure water or domestic pure water. Compared with the prior art scheme of replacing the operating oil with oxygen-free water, the pure water has a lower cost, and the application does not need to set an additional oxygen removal device, which is beneficial to simplify the device structure of the related water supply system and reduce the production cost and operation and maintenance cost of the hydraulic machinery equipment.

[0033] For the adjusting system, the components include a water receiver 1, a force amplifier 2, a main shaft, a hub, a paddle, etc. The water receiver 1 is provided with a rotating shaft head 12. Under the normal operation of the water turbine, the paddle, the hub, the main shaft and the rotating shaft head 12 will rotate together under the action of water force. The force amplifier 2 is provided with a piston 18. A piston rod 3 of the piston 18 is connected with an operating shaft 5 through a snap ring 4. The operating shaft 5 is connected with the rotating arm structure of the paddle. Therefore, under the driving of the high-pressure pure water, the displacement generated by the movement of the piston 18 is transmitted to the rotating arm structure of the paddle through the piston rod 3, the snap ring 4 and the operating shaft 5, so that the rotating arm structure moves and drives the paddle to rotate, thereby achieving the purpose of adjusting the angle of the paddle. The paddle adjusting process is basically the same as that of the prior art, and the patent application CN201811229066.2 proposed by the applicant in an early stage can be referred to.

[0034] In addition, since the water pressure of the pure water is high, a water pressure lock 8 is further arranged in the adjusting system. One end of the water pressure lock 8 is connected with the flange of the rotating shaft head 12 through a first screw 9. The other end of the water pressure lock 8 is connected with the force amplifier 2 through a second screw 10, so as to ensure the connection reliability between the water receiver 1 and the force amplifier 2, and make them adapt to the working environment with high water pressure.

[0035] For the anti-blocking system, a first cylinder sleeve 11 and a second cylinder sleeve 13 are arranged. The first cylinder sleeve 11 is arranged on the outer wall of the rotating shaft head 12. The second cylinder sleeve 13 is arranged on the side of the first cylinder sleeve 11 away from the rotating shaft head 12, that is, the first cylinder sleeve 11 is arranged between the second cylinder sleeve 13 and the rotating shaft head 12. Meanwhile, the rotating shaft head 12 and the first cylinder sleeve 11 are provided with positioning devices, such as the first positioner P1 and the second positioner P2 shown in the accompanying drawings. Figure 2 The rotating shaft head 12 and the second cylinder sleeve 13 are provided with positioning devices, such as the first positioner P1 and the second positioner P2 shown in the accompanying drawings. Figure 2The third positioner Q1 and the fourth positioner Q2 shown in the middle, the structure of any positioning device includes a bearing; so that the first cylinder sleeve 11, the second cylinder sleeve 13, the rotating shaft head 12 form a double-layer anti-blocking structure, on the one hand, the positioning device limits the position of the assembly between the first cylinder sleeve 11, the second cylinder sleeve 13, the rotating shaft head 12, on the other hand, the rotating shaft head 12 in the rotating process, the first cylinder sleeve 11, the second cylinder sleeve 13 will not rotate with it, so that the anti-blocking system always keeps a static state, so that there is no relative motion between it and the first high-pressure water pipe 16a, the second high-pressure water pipe 16b, which ensures the stability of the connection between the anti-blocking system and the first high-pressure water pipe 16a, the second high-pressure water pipe 16b, and is beneficial to improve the reliability of the equipment operation; preferably, any of the above positioning devices adopts a ceramic positioner.
