Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic generators, and specifically relates to a super-large hydraulic generator. Background Art

[0002] Hydropower generation is a science and technology that studies technical and economic issues such as the engineering construction and production operation of converting water energy into electrical energy. The water energy utilized in hydropower generation is mainly the potential energy stored in water bodies. To achieve the conversion of water energy into electrical energy. With the increasing depletion of non-renewable energy sources such as coal, oil, and natural gas, as well as the emergence of problems such as climate warming and environmental deterioration, the redevelopment and reuse of hydropower generation have received great attention from the domestic and international communities. Wind power generation and solar power generation have small power generation capacity, large investment, high power generation cost, intermittent and unstable power generation operation, large floor area, and are difficult to maintain.

[0003] The contact area between the traditional blade and water is limited, and it is unable to fully capture and utilize the water flow energy. In the flood discharge scenario, the water flow velocity is high and the flow rate is large, but the design of the traditional blade cannot effectively expand the contact range with the water flow, resulting in a large amount of water energy not being effectively converted into electrical energy, causing waste of water energy resources. The traditional blade has insufficient ability to guide and utilize the water flow, and the water flow stays on the blade surface for a short time, unable to form enough torque to drive the generator shaft, making the water energy conversion efficiency low and unable to effectively convert the huge water energy impact generated by the dam flood discharge column into a large amount of clean electrical energy, making it difficult to meet the growing energy demand.

[0028] 1.

[0043] Embodiment

[0044] Please refer to Figure 1-8 , the present invention provides a technical solution: a super-large water conservancy generator, including a cross beam 1, a water turbine rotor assembly 6 is provided on one side of the cross beam 1, a brake assembly 2 is provided on one side of the water turbine rotor assembly 6, and the brake assembly 2 is used to stop the rotation of the water turbine rotor assembly 6; a connecting assembly 3 is provided on one side of the water turbine rotor assembly 6, and a generator main body 7 and a gearbox 8 are respectively provided on one side of the water turbine rotor assembly 6;

[0045] The water turbine rotor assembly 6 includes two steel rings 61 and a first rotating shaft 610. A number of first fixing rods 67 and second fixing rods 68 are respectively fixed to the inner walls of the steel rings 61. A second fixing frame 69 is fixedly sleeved outside the first rotating shaft 610. The cross-sectional shape of the second fixing frame 69 can be pentagonal or hexagonal, and a number of mounting seats 611 are fixed outside the second fixing frame 69; the first fixing rods 67 and the second fixing rods 68 connect and fix the steel rings 61 to the first arc-shaped plate 613 and the second arc-shaped plate 614 to form a trinity joint, making the connection more firm; counterweights can be installed on one side of the first fixing rods 67 and the second fixing rods 68 to adjust the dynamic balance and static balance of the water turbine rotor assembly 6.

[0046] One side of the mounting seat 611 is connected to a mounting plate 612 by bolts. A main blade 63 is fixed to one side of the mounting plate 612, and a secondary blade 64 is fixed to one side of the main blade 63; the plate surfaces of the main blade 63 and the secondary blade 64 are made of large I-beams, and the width of the secondary blade 64 is greater than that of the main blade 63; wear-resistant coatings for preventing mud and sand erosion (not shown in the figure) are provided at the parts of the plate surfaces of the main blade 63 and the secondary blade 64 where the water column flows; heightening baffles 66 are fixed to one side of both the main blade 63 and the secondary blade 64. The heightening baffles 66 are used to expand the contact area with water. A support rod 62 is fixed between adjacent main blades 63 and secondary blades 64, and the angle between the heightening baffles 66 and the main blade 63 and the secondary blade 64 is 125°-135°.

[0047] The rotational speed calculation formula of the water turbine rotor assembly 6 is:

[0048]

[0049] where the flow velocity is the flow rate of the dam's flood discharge water column per second, and the water turbine rotor diameter is the diameter of the steel ring 61.

[0050] When the height drop of the flood discharge water column is 10 meters and the water flow rate is 45000 cubic meters per minute, with the water turbine rotor assembly 6 of the present invention, the generator is expected to be 1000 MW per hour.

[0051] On one side of the main blade 63, there is a drainage groove 616 located on one side of the secondary blade 64. A limiting frame 615 is fixed between adjacent main blades 63, which divides the flood discharge water column of the dam of the hydropower station into two parts when it falls. A large part directly flushes onto the blade surface of the main blade 63 first, and then only a small part of the water column can pass through the drainage groove 616 of the main blade 63 to flush onto the surface of the secondary blade 64. In an instant, the drop time and drop distance of the water column are increased, effectively reducing the scouring area of the water column flow on the main blade 63, and also reducing the huge impact pressure of the water column flood on the main blade 63. The flowing water will also fall onto the blade surface of the secondary blade 64 in an instant, increasing the water flow pressure on the secondary blade 64, so that the huge water energy generated by the flood discharge water column can be fully utilized. Multiple water turbine rotor assemblies 6 are installed for multiple gate flood discharges, corresponding to the gate flood discharge water columns, ensuring the stable operation and power generation of the water turbine rotor assembly 6.

[0052] On one side of the main blade 63, a first arc-shaped plate 613 is fixed. On one side of the secondary blade 64, a second arc-shaped plate 614 is fixed. One side of the first fixing rod 67 is fixed to one side of the first arc-shaped plate 613. One side of the second fixing rod 68 is fixed to one side of the second arc-shaped plate 614. The first arc-shaped plate 613 and the second arc-shaped plate 614 are in a hook shape, so that the water flow falling on the main blade 63 and the secondary blade 64 can stay on their surfaces for a moment, increasing the twisting force of the main blade 63 and the secondary blade 64 on the first rotating shaft 610. The multiple main blades 63 and secondary blades 64 of the water turbine rotor assembly 6 effectively resist the huge impact force of the dam flood discharge water column, converting a large amount of water flow energy into a large amount of clean electric energy. The lengths of the main blade 63 and the secondary blade 64 can be set according to needs, and the lengths of the main blade 63 and the secondary blade 64 can be ≥10 meters, converting the huge water energy impact force generated by the dam flood discharge water column of the hydropower station into a large amount of clean electric energy, turning waste into treasure. It can be produced in a factory, assembled according to the water column spraying conditions of the dam, transported, and after a short commissioning, it can use the existing dam flood discharge to wash and generate electricity. The present invention can be produced in a factory, forming an industrial cluster with a large power generation capacity.

[0053] The brake assembly 2 includes a connecting plate 21. On one side of the connecting plate 21, a number of limiting grooves 25 are provided. On one side of the connecting plate 21, a wrench 28 and a second connecting rod 211 are respectively hinged. On one side of the second connecting rod 211, a first fixing frame 23 is hinged.

One side of the wrench 28 is hinged with the first connecting rod 24, and one side of the first connecting rod 24 is hinged with one side of the first fixing frame 23. On one side of the first fixing frame 23, a brake pad 22 located on one side of the steel ring 61 is fixed. The wrench 28 rotates around the hinge point, and the wrench 28 pushes the first connecting rod 24 to drive the first fixing frame 23 to move towards the steel ring 61 side. At the same time, the second connecting rod 211 rotates around the hinge axis with the connecting plate 21.

[0054] One side of the wrench 28 is provided with a clamping groove 29, one side of the wrench 28 is fixed with a rope body 27, and one side of the rope body 27 is fixed with a limiting rod 26; when the outer side of the limiting rod 26 is inserted into the inner side of any one of the limiting grooves 25, one side of the brake pad 22 fits against the outer side of the steel ring 61, and the water wheel rotor assembly 6 is in a stopped state; one side of the connecting plate 21 is fixed with an elastic plate 210, the material of the elastic plate 210 is a metal plate, and one side of the elastic plate 210 is fixed with a clamping block 212. When the clamping block 212 is clamped into the inner side of the clamping groove 29, the brake pad 22 leaves the outer side of the steel ring 61. When the brake assembly 2 is not operating, parts can be replaced, repaired, and the machine can be stopped. The brake assembly 2 cannot be used when it is operating.

One side of the pull ring seat 31 is fixed on one side of the heightening baffle 66. The connecting component 3 is used to resist the expansion force and impact force of the water column scouring on the heightening baffle 66. The number of the connecting components 3 can be selected according to the size of the water wheel rotor assembly 6, and one or several connecting components 3 can be installed.

[0056] Two connecting frames 11 are fixed at the bottom of the cross beam 1, and a through hole 12 located on one side of the wrench 28 is provided on one side of the top of the cross beam 1; the through hole 12 is used for the operator to operate the wrench 28. One side of the connecting frame 11 is rotatably connected to the outer side of the first rotating shaft 610 through a bearing. The top of the connecting plate 21 is fixed to the bottom of the cross beam 1. One end of the first rotating shaft 610 is connected to the second rotating shaft 9 through a flange, and one end of the second rotating shaft 9 is fixed to the input shaft end of the gearbox 8. The output shaft end of the gearbox 8 is fixed to the input shaft end of the generator main body 7.

[0057] A moving module 4, a lifting module 5, a control module 10, and a monitoring module are respectively arranged on the lower side of the cross beam 1; the monitoring module is installed on one side of each main blade 63. The top of the lifting module 5 is fixed to the bottom of the cross beam 1, the bottom of the lifting module 5 is fixed on the top of the moving module 4, the control module 10 is installed on one side of the moving module 4, and both the gearbox 8 and the generator main body 7 are installed on one side of the moving module 4.

[0058] The moving module 4 is used for the water wheel rotor assembly 6 to move forward or backward in the horizontal direction;

[0059] The lifting module 5 is used for the water wheel rotor assembly 6 to rise or fall in the vertical direction;

[0060] The monitoring module is used for monitoring the changes in the reaction water column and water flow in real time;

[0061] The control module 10 receives the feedback information from the monitoring module and issues instructions to control the moving module 4 and the lifting module 5;

[0062] The monitoring module is connected to the control module 10, and the control module 10 is respectively connected to the moving module 4 and the lifting module 5.

[0063] Working principle: When the dam discharges flood, the high-speed water column impacts the water wheel rotor assembly 6 with great kinetic energy. The water flow first contacts the main blade 63, the plate surface of which is made of impact-resistant I-beam and directly bears most of the water flow impact force. The secondary blade 64 receives the remaining water flow through the drainage groove 616 on the side of the main blade 63, forming a water flow distribution with time difference and space difference, effectively dispersing the impact pressure. The heightening baffle 66 expands the contact area between the blade and the water. The hook designs of the first arc plate 613 and the second arc plate 614 enable the water flow to stay on the blade surface for a moment, increasing the torque of the blade on the first rotating shaft 610. Subsequently, the first rotating shaft 610 is connected to the second rotating shaft 9 through a flange, transferring the mechanical energy of the water wheel rotor to the gearbox 8. After the gearbox 8 adjusts the rotational speed, it drives the input shaft of the generator main body 7, and finally converts the mechanical energy into electrical energy; converting the huge water energy impact force generated by the flood discharge water column of the hydropower station dam into a large amount of clean electrical energy, turning waste into treasure, which can be produced in a factory. According to the water column spraying condition of the dam, it can be assembled and transported, and after a short debugging, it can utilize the existing dam flood discharge water to wash and generate electricity. The present invention can be produced in a factory, forming an industrial cluster with a large power generation capacity.

[0064] The operating wrench 28 drives the first fixing frame 23 through the first connecting rod 24 and the second connecting rod 211, enabling the brake pad 22 to fit or leave the steel ring 61. When the limiting rod 26 is inserted into the limiting groove 25, the brake pad 22 completely fits the steel ring 61 to achieve emergency shutdown; when the clamping block 212 of the elastic plate 210 is clamped into the clamping groove 29, the brake pad 22 disengages and the rotation is restored.

[0065] The iron chain 32 and the tensioner 33 are connected to the column 35 through the pull ring 34 to resist the expansion force and impact force of the water flow on the heightening baffle 66 and ensure the stability of the blade structure;

[0066] The monitoring module real-time detects the changes in the water column height, flow rate and flow velocity, and feeds the data back to the control module 10. The control module 10 instructs the moving module 4 and the lifting module 5 to adjust the position of the water wheel rotor according to the water flow change, optimizing the water flow impact angle. The moving module 4 and the lifting module 5 are integrated under the cross beam 1 to achieve horizontal and vertical adjustment. The generator main body 7 and the gearbox 8 are installed on one side of the moving module 4, facilitating overall maintenance and debugging.

[0067] In summary, by combining the main blade 63 and the auxiliary blade 64 to form a water flow distribution with a time difference and a space difference through the drainage groove 616, the impact pressure is effectively dispersed, the impact force borne by a single component is reduced, the heightening baffle 66 expands the contact area between the blade and water, enhances the ability of the blade to capture and utilize water flow, and the hook designs of the first arc plate 613 and the second arc plate 614 enable the water flow to stay on the blade surface for a moment, increasing the torque of the blade on the first rotating shaft 610. The huge water energy impact force generated by the dam flood discharge water column is effectively converted into a large amount of clean electric energy, realizing turning waste into treasure, greatly improving the utilization rate of water energy resources, and increasing energy output.

[0068] By operating the wrench 28 to directly drive the first fixing frame 23 through the first connecting rod 24 and the second connecting rod 21 '1, the possible failures or delays in the intermediate links are reduced, ensuring a rapid response in case of an emergency and timely making the brake pad 22 fit the steel ring 61 to achieve rapid shutdown, effectively avoiding safety accidents caused by equipment out of control; when the clamping block 212 of the elastic plate 210 is inserted into the clamping groove 29, the brake pad 22 is separated from the steel ring 61 to resume rotation, so that in the normal operation state of the equipment, the brake pad 22 and the steel ring 61 are in a stable separated state and will not accidentally fit due to external slight interference or the vibration of the equipment itself, resulting in shutdown.

[0069] The monitoring module is used to detect the changes in the water column height, flow rate and flow velocity in real time and feedback them to the control module 10. According to the instructions, the control module 10 enables the moving module 4 and the lifting module 5 to adjust the position of the water turbine rotor assembly 6, optimize the water flow impact angle, ensure that the water turbine rotor assembly 6 is always in the best water receiving position, capture the water flow energy to the greatest extent, efficiently convert the water flow energy into mechanical energy, and then improve the overall power generation efficiency of the generator and reduce the energy loss caused by the change of water flow conditions.
