Technical Field
[0001] This utility model relates to the field of water turbine technology, specifically a simulation device for simulating the opening of guide vanes of a hydropower station turbine. Background Technology
[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. Essentially, it works by having water flow impact an impeller or runner to drive a generator to produce electricity or directly power a mechanical load. As the core equipment of hydropower generation, it undertakes the crucial task of converting the potential or kinetic energy of water into electrical energy. It can also be applied to agricultural irrigation, industrial drives, and other fields.
[0003] Regarding the above and existing related technologies: In water conservancy courses, simulation models are used to help students understand the operation of water turbines. The use of simulation models requires support structures. Since most support structures lack convenient explanation capabilities, teaching difficulties can easily arise. Therefore, a simulation device for simulating the guide vane opening of hydropower station turbines is proposed to address the above problems. Utility Model Content

A secondary model is fixedly connected to the inner surface of the main model. The protective device is set on the surface of the main model and includes a placement plate. The placement plate is sleeved on the surface of the main model. Two rotating plates are rotatably connected to the surface of the placement plate. A fixing block is fixedly connected to the upper surface of the placement plate. A limiting block is rotatably connected to the surface of the fixing block. The limiting block is located on one side of the two rotating plates. Pushing the limiting block causes it to rotate on the surface of the fixing block. The limiting block rotates to the side wall of the two rotating plates. By setting the placement plate, rotating plates, fixing block and limiting block, the main model can be protected, and the main model and secondary model can be easily observed.
[0006] Preferably, two storage blocks are fixedly connected to the side wall of the placement plate, and two locking blocks are fixedly connected to both sides of the main model. The locking blocks are inserted into the inner surface of the storage blocks, and the storage blocks and locking blocks can restrict the position of the main model to a certain extent.
[0007] Preferably, the inner walls of the storage block and the card block are threaded with positioning pins. After the card block is inserted into the inner wall of the storage block, the positioning pins are rotated to the inner walls of the storage block and the card block, and the positioning pins can restrict the position of the card block.
[0008] Preferably, the inner walls of the placement plate and the rotating plate are threaded with limit pins. After the rotating plate rotates to a suitable angle, the limit pins are rotated to the inner walls of the placement plate and the rotating plate, and the limit pins can limit the angle of the rotating plate.
[0009] Preferably, a magnetic suction plate is fixedly connected to the side wall of the rotating plate. When the magnetic buckle is placed on the surface of the photo, the magnetic buckle is attracted by the magnetic suction plate. By setting the magnetic suction plate, it is convenient to fix the real object image.
[0010] Preferably, the side wall of the placement board is provided with a writing device, which includes two fixed plates. The side walls of the two fixed plates are fixedly connected to the side wall of the placement board. A movable block is slidably connected to the inner wall of the fixed plate. A writing board is fixedly connected to one end of the two movable blocks that are close to each other. The movable block slides on the inner wall of the fixed plate.

The side wall of the magnetic block and the side wall of the moving block are magnetically attracted to each other, and the magnetic block attracts the moving block. By setting the connecting block and the magnetic block, the position of the moving block can be restricted.
[0012] The advantages of this utility model are:
[0013] 1. When explaining the main model and sub-model, this utility model pushes the limiting block to rotate on the surface of the fixed block. After the limiting block moves away from the rotating plate, the rotating plate is pushed to rotate on the surface of the placement plate. After the rotating plate rotates to a suitable angle, the positioning pin is rotated to the inner wall of the placement plate and the rotating plate. Then, the main model is pushed to make the main model drive the card block to slide. The card block is inserted into the inner wall of the storage block. Then, the limiting pin is rotated to the inner wall of the storage block and the card block. During the explanation, the real object photo is attached to the magnetic plate, and then the magnetic buckle is attached to the surface of the photo. The magnetic buckle will be attracted by the magnetic plate. By setting the entire device, the main model can be supported and protected, reducing the possibility of damage to the main model and sub-model. At the same time, it can also facilitate the explanation and increase the teaching effect.
[0014] 2. When teaching is required, this utility model allows the writing board to be pulled to slide the moving block. The moving block slides on the inner wall of the fixed plate. When the writing board moves, it will adhere to the magnetic block on the connecting block. The magnetic block will attract the writing board, and then text can be written on the writing board. When it is not needed, the writing board can be pushed to retract, and the writing board will be attracted to the magnetic block on the other side. By setting up the whole device, it is convenient to write text and assist the main model and the sub-model in teaching. Attached Figure Description
