[0002] A water turbine is a device that uses the energy of water flow to drive a generator or other mechanical equipment. It is usually installed in a hydropower station downstream of a river, reservoir or dam with strong water flow to convert the kinetic energy of water flow into mechanical energy or electrical energy. The working principle of a water turbine is to use the kinetic energy of water flow to drive the rotation of the water turbine blades, and to generate electricity by driving the generator to rotate through the main shaft of the water turbine. Water turbines are usually divided into two types: vertical axis water turbines and horizontal axis water turbines. The appropriate type is selected according to different water flow conditions and usage requirements. Water turbines have the advantages of high efficiency, environmental protection, and renewable. They are an important clean energy power generation equipment. They can adjust the working state according to the size and quality of the water flow, and have high stability and reliability.

[0003] However, since the main shaft inside the existing turbine will cause certain damage to the outer surface of the main shaft after long-term friction with the water flow, it is necessary to use a side leak-proof and anti-wear plate to prevent the water flow from directly contacting the main shaft, thereby achieving a barrier effect through itself. However, the subsequent disassembly process of the side leak-proof and anti-wear plate is more troublesome, and the staff needs to spend a lot of time to remove it. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 6 As shown, the utility model provides a quickly detachable side leak-proof and wear-resistant plate for a turbine, comprising a turbine casing 1, a movable component 2 is installed inside the turbine casing 1, a limiting component 3 is installed inside the movable component 2, the limiting component 3 comprises a telescopic spring 31, a limiting column 32 and a pushing plate 33, one end of the telescopic spring 31 is fixedly connected to one end of the limiting column 32, and the outer surface of the limiting column 32 is provided with a groove that is compatible with the pushing plate 33, and the top of the pushing plate 33 is fixedly connected to the inside of the groove.

[0023] The above scheme is adopted: through the setting of the telescopic spring 31, the limit column 32 can be driven to move freely inside the movable plate 21 by utilizing its own contractility, and at the same time, the push plate 33 can be used to clamp one end of the limit column 32 into the inside of the circular hole, thereby fixing the position of the movable plate 21 on the inner wall of the drainage frame 11. Through the setting of the push plate 33, one end of the limit column 32 can be conveniently removed from the inside of the circular hole, and the fixation of the movable plate 21 can be released, which is convenient for the subsequent removal of the movable plate 21.

[0024] like Figure 5 to Figure 6As shown, the movable assembly 2 includes a movable plate 21, a movable plate 22, a movable spring 23, and a pulling plate 25. One end of the movable plate 21 is slidably connected to the inner wall of the first slide groove, and the movable plate 21 and the movable plate 22 are located directly above the main shaft. The other end of the telescopic spring 31 is fixedly connected to the inner wall of the movable plate 21, and the outer surface of the pushing plate 33 is slidably connected to the inside of the movable plate 21. The outer surface of the movable plate 22 is tightly connected to the inner wall of the movable plate 21. The two ends of the movable spring 23 are respectively fixedly connected to the connection between the movable plate 22 and the movable plate 21. An L-shaped hole 211 is provided at the bottom of the movable plate 21, and the outer surface of the pulling plate 25 is in contact with the inner wall of the L-shaped hole 211. The top of the pulling plate 25 is movably connected to the bottom of the movable plate 22, and the movable plates 22 are connected to each other by magnetic stones.

[0025] By adopting the above scheme: through the setting of the movable plate 21, when the movable plate 21 moves, it can drive the movable plate 22, the limit column 32 and the telescopic spring 31 to move synchronously, so that the cross section of the limit column 32 and the circular hole coincide with each other after the movement, and one end of the limit column 32 is brought into the inside of the circular hole under the inertia of the telescopic spring 31. Through the setting of the movable spring 23, when the movable spring 23 loses the restriction of the pulling plate 25, it will drive the movable plate 22 to move toward the outside of the movable plate 21, so that the movable plate 22 and the movable plate 22 They can be connected by a magnetic stone, and the movement of the movable plate 22 and the movable plate 21 can effectively reduce the damage caused by the direct contact between the water flow and the main shaft. Through the setting of the L-shaped hole 211 and the pulling plate 25, the pulling plate 25 can be used to bring the movable plate 22 into the interior of the movable plate 21. At the same time, due to the characteristics of the L-shaped hole 211 itself, the position of the pulling plate 25 after movement can be fixed, thereby cooperating with the pushing plate 33 to facilitate the staff to take out the movable component 2 and the limiting component 3 from the inside of the drainage frame 11.

[0026] The working principle and usage process of the utility model are as follows: first, the operator pushes the pushing plate 33 toward the direction of the movable plate 22, so that the limiting column 32 enters the interior of the movable plate 21 as a whole with the cooperation of the pushing plate 33 and the telescopic spring 31, and then, one end of the movable plate 21 is brought into contact with the first slide groove opened on the inner wall of the drainage frame 11, and the movable plate 21 is moved upward as a whole by using the first slide groove, so that the moved movable plate 21 is located above the main shaft. During this process, the movable plate 22 will move synchronously with the movable plate 21.

[0027] When the cross section of the limit post 32 coincides with the circular hole, the push plate 33 is released, so that one end of the limit post 32 will be clamped inside the circular hole under the inertia of the telescopic spring 31, thereby fixing the position of the movable plate 21. At this time, the pulling plate 25 is slid toward one end of the L-shaped hole 211, so that the L-shaped hole 211 releases the restriction on the pulling plate 25. When the movable spring 23 loses the pressure brought by the pulling plate 25, it will drive the movable plate 22 to move toward the outside of the movable plate 21, so that the position between the movable plate 22 after movement can be fixed by the magnetic stone to prevent damage caused by friction after the water flow directly contacts the main shaft. Using the same principle, the limit post 32 and the movable plate 22 are brought to their original positions by the pushing plate 33 and the pulling plate 25, thereby facilitating subsequent disassembly. At this point, the overall operation process is completed.
