Technical Field

[0001] This utility model relates to the field of hydropower technology, and in particular to impeller assemblies for hydropower generation. Background Technology

[0002] Hydropower is a renewable energy source with relatively low environmental impact. The impeller assembly for hydropower is a core component of the hydropower system. It converts the energy of water flow into mechanical energy, which in turn drives the generator to generate electricity. Therefore, a type of impeller assembly for hydropower is used.

[0003] To address this, patent CN213870106U discloses a hydroelectric impeller, including a hub with blades fixedly connected to its outer surface. Both the hub and blades have a first functional layer, comprising an electroplated zinc layer and a chlorinated rubber aluminum powder anti-rust coating. A second functional layer is provided outside the first functional layer. This invention, through the electroplated zinc layer, provides excellent corrosion resistance; through the chlorinated rubber aluminum powder anti-rust coating, it offers good water resistance, rust prevention, corrosion resistance, and resistance to alternating wet and dry conditions; through the high-strength polyurethane waterproof coating, it provides strong acid and alkali resistance, corrosion resistance, and water impermeability; and through the high-density polyethylene coating, it offers excellent corrosion resistance and wear resistance. This invention solves the problem that existing impellers, due to poor protection during operation, are prone to damage, reducing their service life and affecting power generation.

[0004] While the aforementioned hydroelectric impeller solves the problem of poor protection performance leading to easy damage to existing impellers during operation, its applicability is limited due to its inconvenient filtration, making it difficult to prevent impurities from entering the impeller assembly and protecting the normal operation of the equipment. Furthermore, it is inconvenient to clean the stainless steel conical filter screen. Utility Model Content

[0005] The purpose of this invention is to provide a turbine assembly for hydropower generation, in order to solve the defect of existing turbine assemblies for hydropower generation that are inconvenient for filtering.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a turbine assembly for hydropower generation, including a housing;

[0007] The top of the housing is fixed with a cover, the inside of the housing is provided with a rotating shaft, the outside of the rotating shaft is provided with a disc, and both ends of the disc are equipped with a disassembly structure on the outside of the rotating shaft.

[0008] The bottom end of the disk is uniformly fixed with a protective structure;

[0009] A water inlet pipe is fixed to one side of the bottom of the housing, and a drain pipe is fixed to the other side of the bottom of the housing. A filter structure is installed at one end of the water inlet pipe. The filter structure includes a fixed frame set at one end of the water inlet pipe. A stainless steel conical filter screen is fixed to one side of the fixed frame. Both sides of the inside of the water inlet pipe on the other side of the fixed frame are provided with snap-fit ​​grooves. Each snap-fit ​​groove is provided with a snap-fit ​​block inside, and each snap-fit ​​block is provided with a reserved groove inside.

[0010] When using this device, the inclusion of a filtration structure facilitates the cleaning of the stainless steel conical filter screen, thereby improving the applicability of the impeller assembly for hydropower generation; the inclusion of a disassembly structure facilitates maintenance and repair, thereby improving the stability of the impeller assembly during use; and the inclusion of a protective structure facilitates reinforcement, thereby improving the ease of use of the impeller assembly for hydropower generation.

[0011] Preferably, handles are fixed at both ends of the fixing frame, and the snap-fit ​​block and the water inlet pipe form an engaging structure through snap-fit ​​grooves. One end of the snap-fit ​​block extends to the outside of the water inlet pipe and is fixedly connected to one side of the fixing frame. Under the action of the snap-fit ​​block and the snap-fit ​​groove, the stainless steel conical filter screen and the water inlet pipe are fixed or separated. Under the action of the stainless steel conical filter screen, impurities and particles in the water can be intercepted, preventing impurities from entering the interior of the housing.

[0012] Preferably, the top end of the rotating shaft extends to the outside of the cover, and the bottom end of the rotating shaft extends to the inside of the housing, forming a rotating structure with the housing. A stainless steel filter screen is fixed to one end of the drain pipe. The stainless steel filter screen prevents impurities from entering the interior of the housing.

[0013] Preferably, the disassembly structure includes a fixed plate, fixing bolts, a limiting plate, a limiting groove, and a movable plate. The limiting groove extends through both sides of the interior of the disc, and a limiting plate is provided inside each limiting groove. A fixed plate is fixed to the outer wall of the rotating shaft at the top of the disc, and a movable plate is fitted onto the outer wall of the rotating shaft at the bottom of the disc. Fixing bolts are evenly distributed throughout the interior of both the fixed plate and the movable plate. The cooperation of the limiting plate and the limiting groove allows the disc to drive the rotating shaft to rotate, and the fixing bolts allow the movable plate and the fixed plate to be fixed or separated.

[0014] Preferably, the movable disk and the fixed disk are fixedly connected by fixing bolts, and one side of the limiting plate extends to the outside of the disk and is fixedly connected to the outer wall of the rotating shaft. The limiting plate and the disk form a sliding structure through the limiting groove. This allows the disk and the rotating shaft to be fixed or separated from each other. When the disk drives the blade to separate from the rotating shaft, it is convenient to maintain and repair the blade.

[0015] Preferably, the protective structure includes blades, an anti-corrosion layer, and reinforcing ribs. The blades are uniformly fixed to the bottom end of the disk, and an anti-corrosion layer is provided on the outer side of each blade. Reinforcing ribs are uniformly fixed to one side of the top of the anti-corrosion layer. The anti-corrosion layer improves the blades' wear resistance, corrosion resistance, and thermal stability, thereby extending their service life.

[0016] Preferably, the anti-corrosion layer is actually a nickel-based alloy coating, and the top end of the reinforcing rib is fixedly connected to the bottom end of the disk. The reinforcing rib enhances the strength and rigidity of the blade, thereby improving its durability and stability, and effectively preventing deformation and twisting caused by uneven stress.

[0017] The advantages of the impeller assembly for hydropower generation provided by this utility model are as follows:

[0018] With a filter structure, the stainless steel conical filter screen and the inlet pipe are fixed or separated by the snap-fit ​​blocks and snap-fit ​​grooves. The stainless steel conical filter screen can intercept impurities and particles in the water, preventing impurities from entering the interior of the shell and avoiding damage to the blades due to impurity blockage. This ensures the long-term stable operation of the equipment. By moving the fixed frame with the handle, the fixed frame can separate the stainless steel conical filter screen from the inlet pipe, making it easy to clean the stainless steel conical filter screen. This device realizes the function of easy cleaning of the stainless steel conical filter screen, thereby improving the applicability of the impeller assembly for hydropower generation.

[0019] With a disassembly structure, the disc can drive the shaft to rotate under the cooperation of the limiting plate and the limiting groove. Under the action of the fixing bolts, the movable disc and the fixed disc can be fixed or separated from each other, thereby fixing or separating the disc and the shaft. When the disc drives the blade to separate from the shaft, it is convenient to maintain and repair the blade. This realizes the function of easy maintenance and repair of the device, thereby improving the stability of the impeller assembly for hydropower generation during use.

[0020] By incorporating a protective structure and an anti-corrosion layer, the wear resistance, corrosion resistance, and thermal stability of the blades can be improved, thereby extending their service life. The reinforcing ribs enhance the strength and rigidity of the blades, thus improving their durability and stability. At the same time, they can effectively prevent deformation and twisting of the blades due to uneven stress, enabling the device to be easily reinforced and improving the convenience of using the turbine assembly for hydropower generation.

[0028] Please see Figures 1-5 The impeller assembly for hydroelectric power generation provided by this utility model includes a housing 1, a cover 4 fixed to the top of the housing 1, a rotating shaft 5 disposed inside the housing 1, a disc 7 disposed outside the rotating shaft 5, and a disassembly structure 8 installed on the outer side of the rotating shaft 5 at both ends of the disc 7. The disassembly structure 8 includes a fixed disc 801, a fixing bolt 802, a limiting plate 803, a limiting groove 804, and a movable disc 805. The limiting groove 804 extends through both sides inside the disc 7, and a limiting position is provided inside the limiting groove 804. A fixed plate 801 is fixed on the outer wall of the rotating shaft 5 at the top of the disc 7, and a movable plate 805 is sleeved on the outer wall of the rotating shaft 5 at the bottom of the disc 7.

[0029] Reference Figure 2 and Figure 4As shown, the disc 7 and the movable disc 805 are sequentially placed on the outside of the rotating shaft 5, so that the limiting plate 803 moves into the inside of the limiting groove 804. Under the cooperation of the limiting plate 803 and the limiting groove 804, when the blade 901 drives the disc 7 to rotate, the disc 7 can drive the rotating shaft 5 to rotate. Under the action of the fixing bolt 802, the movable disc 805 and the fixed disc 801 are fixed or separated from each other, thereby fixing or separating the disc 7 and the rotating shaft 5. When the disc 7 drives the blade 901 to separate from the rotating shaft 5, it is convenient to maintain and repair the blade 901.

Under the action of the anti-corrosion layer 902, the wear resistance, corrosion resistance and thermal stability of the blade 901 can be improved, thereby extending the service life of the blade 901. Under the action of the reinforcing rib 903, the strength and rigidity of the blade 901 can be enhanced, thereby improving the durability and stability of the blade 901. At the same time, it can effectively prevent the blade 901 from deforming and twisting due to uneven stress, and further prevent the blade 901 from breaking at the weld joint with the disk 7.

[0033] Reference Figure 2 and Figure 3As shown, by moving the handle to fix the frame 302, one end of the snap-fit ​​block 305 abuts against one end of the snap-fit ​​groove 303, pushing the frame 302, and under the action of the reserved groove 304, the frame 302 moves the snap-fit ​​block 305 into the inside of the snap-fit ​​groove 303. At this time, the stainless steel conical filter screen 301 and the water inlet pipe 2 are fixed to each other. Under the action of the stainless steel conical filter screen 301, impurities and particles in the water can be intercepted, preventing impurities from entering the interior of the housing 1 and avoiding damage to the blades 901 due to impurities blockage, thereby ensuring the long-term stable operation of the equipment.
