Description

Technical Field

[0001] This utility model relates to the field of water turbine technology, and in particular to a wide-load water turbine for hydropower plants. Background Technology

[0002] Wide-load turbines are hydro-generator units that are designed with special structures and optimized controls, enabling them to operate safely, stably, and efficiently in load ranges far exceeding those of conventional units (usually as low as 45% or even lower than the rated load). The core of these turbines is to adapt to the peak-shaving, renewable energy consumption, and ecological flow control requirements of new power systems.

[0003] Wide-load turbines are essentially a system integration of hydraulic design, structural engineering and intelligent control. Their core objective is to break through conventional load boundaries and achieve "safe, stable, efficient and flexible" operation under all working conditions, providing reliable regulating power support for new power systems.

[0004] Existing hydropower plants use wide-load turbines, whose turbine runner blade angles can be adjusted. However, each adjustment involves adjusting all runner blades simultaneously, making it impossible to independently control the rotation of the runner blades, resulting in low practicality.

[0005] Therefore, it is necessary to provide a wide-load turbine for hydropower plants to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a wide-load turbine for hydropower plants, solving the problem of low practicality due to the inability to independently control the rotation of the runner blades. To address the aforementioned technical problems, this utility model provides a wide-load turbine for hydropower plants, comprising a main shaft. A drive assembly is installed at the top of the main shaft. Several sets of rotating shafts are rotatably connected to the side walls of the main shaft. Each set of rotating shafts extends into the main shaft. An adjustment assembly is installed at the end of each set of rotating shafts inside the main shaft. An installation assembly is connected to the outer end of each set of rotating shafts. A locking assembly is installed between the installation assembly and the outer wall of the rotating shaft. A cylinder is connected to the installation assembly, and a turbofan blade is fixedly installed on the outer wall of each set of cylinders.

[0007] Preferably, the drive assembly includes a motor, which is fixed inside the top of the main shaft, and a bevel gear is fixedly installed at the output end of the motor.

[0008] Preferably, the adjustment assembly includes cylinders, each group of cylinders is fixedly connected to the end of each rotating shaft located inside the main shaft, and a bevel gear is fixedly installed at the output end of each group of cylinders.

[0009] Preferably, the mounting assembly includes a limiting groove, which is formed on the outer wall of the rotating shaft and extends through the outer end of the rotating shaft. A limiting block is inserted into the inner wall of the limiting groove, and the outer wall of the limiting block is fixedly connected to a cylinder. The top of the limiting block is in contact with a locking assembly.

[0010] Preferably, the locking component includes mounting blocks, two sets of mounting blocks evenly fixing the outer wall of the rotating shaft outside the entry end of the limiting groove, and an arc-shaped plate rotatably connecting the two sets of mounting blocks, the inner wall of the arc-shaped plate being in contact with the outer wall of the limiting block.

[0011] Preferably, a groove is formed on the outer wall of the other end of the arc-shaped plate, and a bolt is threadedly connected between the inner wall of the groove and the outer wall of the rotating shaft.

[0012] Preferably, a control device is fixedly installed on the inner wall of the spindle, and the control device is electrically connected to the cylinder.

[0013] Compared with related technologies, the wide-load turbine for hydropower plants provided by this utility model has the following beneficial effects:

[0014] Several sets of cylinders can simultaneously push bevel gear two into contact with bevel gear one, or they can push bevel gear two into contact with bevel gear one individually. When the motor output end rotates, bevel gear one drives bevel gear two to rotate. This allows for simultaneous control of the turbine blades or individual control of a specific set of turbine blades, improving the versatility of adjustment and better controlling the water flow.

[0015] After loosening the bolts, the locking of the arc plate can be released. Rotate the arc plate outward to move it away from the limiting groove and into the outside of the end. This makes it easy to remove the limiting block with the cylinder installed from inside the limiting groove. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 A schematic diagram of a preferred embodiment of a wide-load hydro turbine for hydropower plants provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the internal structure of the spindle shown. Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 2 The enlarged schematic diagram of section C is shown. A wide-load turbine for a hydropower plant includes: a main shaft 1, a drive assembly 5 installed at the top inside the main shaft 1, several sets of rotating shafts 9 uniformly rotatably connected to the side wall of the main shaft 1, each set of rotating shafts 9 penetrating into the interior of the main shaft 1, an adjustment assembly 6 installed at the end of each set of rotating shafts 9 inside the main shaft 1, an installation assembly 4 connected to the outer end of each set of rotating shafts 9, a locking assembly 3 installed between the installation assembly 4 and the outer wall of the rotating shaft 9, a cylinder 8 connected to the installation assembly 4, and a turbofan blade 2 fixedly installed on the outer wall of each set of cylinders 8.

[0024] The drive assembly 5 includes a motor 51, which is fixed inside the top of the main shaft 1. A bevel gear 52 is fixedly installed at the output end of the motor 51. When the angle of the turbine blade 2 needs to be adjusted, the adjustment assembly 6 will contact the bevel gear 52, so that when the output end of the motor 51 drives the bevel gear 52 to rotate, the turbine blade 2 on the corresponding rotating shaft 9 will be driven to rotate through the adjustment assembly 6.

[0025] The adjustment component 6 includes cylinders 61. Each set of cylinders 61 is fixedly connected to the inner end of each set of rotating shafts 9 located on the main shaft 1. Each set of cylinders 61 has a bevel gear 62 fixedly installed at its output end. Several sets of cylinders 61 can simultaneously push bevel gear 62 to contact bevel gear 52, or they can push bevel gear 62 to contact bevel gear 52 individually. When the output end of the motor 51 rotates, bevel gear 52 drives bevel gear 62 to rotate. This allows for simultaneous control of the turbine blades 2 or individual control of a certain set of turbine blades 2, improving the adjustment versatility and better controlling the water flow.

[0026] The mounting component 4 includes a limiting groove 41, which is formed on the outer wall of the rotating shaft 9 and extends through the outer end of the rotating shaft 9. A limiting block 42 is inserted into the inner wall of the limiting groove 41. The outer wall of the limiting block 42 is fixedly connected to the cylinder 8. The top of the limiting block 42 is in close contact with the locking component 3. Both the limiting groove 41 and the limiting block 42 are T-shaped, which makes the limiting block 42 and the limiting groove 41 have high stability when inserted into each other.

[0027] The locking component 3 includes mounting blocks 32. Two sets of mounting blocks 32 are evenly fixed to the outer wall of the rotating shaft 9 outside the entry end of the limiting groove 41. An arc plate 31 is rotatably connected between the two sets of mounting blocks 32. The inner wall of the arc plate 31 is in contact with the outer wall of the limiting block 42. Rotating the arc plate 31 outwards makes it leave the entry end of the limiting groove 41, so that the limiting block 42 with the cylinder 8 installed can be easily removed from the inside of the limiting groove 41.

[0028] A groove 33 is formed on the outer wall of the other end of the arc plate 31. A bolt 34 is threaded between the inner wall of the groove 33 and the outer wall of the rotating shaft 9. After loosening the bolt 34, the locking of the arc plate 31 can be released.

[0029] A control device 7 is fixedly installed on the inner wall of the main shaft 1. The control device 7 is electrically connected to the cylinder 61 and is a PLC controller.

[0030] The working principle of a wide-load water turbine for hydropower plants provided by this utility model is as follows:

[0031] By adjusting the settings of component 6, a certain group of turbine blades 2 can be independently controlled to adjust their angle after being connected to the drive component 5. At the same time, component 6 can also control multiple turbine blades 2 to rotate after being connected to the drive component 5. After unlocking component 3, damaged turbine blades 2 can be quickly replaced by installing component 4.

[0032] Compared with related technologies, the wide-load turbine for hydropower plants provided by this utility model has the following beneficial effects:

[0033] Several sets of cylinders 61 can simultaneously push bevel gear 2 62 to contact bevel gear 1 52, or push bevel gear 2 62 to contact bevel gear 1 52 individually, so that when the output end of motor 51 rotates, bevel gear 1 52 drives bevel gear 2 62 to rotate, thereby enabling simultaneous control of the rotation of turbine blades 2, or individual control of a certain set of turbine blades 2, improving the diversity of adjustment and better controlling the water flow.

[0034] After loosening bolt 34, the locking of arc plate 31 can be released. Rotate arc plate 31 outward to move it away from limiting groove 41 and into the outside of the end. Then, the limiting block 42 with cylinder 8 installed can be easily removed from inside limiting groove 41.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
