DETAILED DESCRIPTION

[0026] The following will be combined with 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 of 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.

[0027] Example 1

[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a hydropower generation device, including a spiral volute 1 and a base plate 6, the top of the base plate 6 is fixed by welding a block 601, the outer side of the fixed block 601 is rotatably connected to a rotating arm 602, the outer side of the rotating arm 602 is rotatably connected to a rotating rod 603, the outer side of the rotating rod 603 is rotatably connected to a turntable 604, the outer side of the turntable 604 is welded and fixed with a fixing frame 605, the outer side of the fixing frame 605 is fixedly connected with a scraper 606 by a buckle, the top of the base plate 6 is fixed with a sleeve 608 by welding, and a cavity is opened inside the sleeve 608, a piston 607 is slidably connected inside the cavity of the sleeve 608, and the base plate 6 is tightly arranged on the inner arm of the spiral volute 1.

[0029] In this embodiment, when water enters the base plate 6, the piston 607 is controlled to slide upward inside the sleeve 608. When the sleeve 608 slides upward, the sleeve 608 drives the rotating rod 603 to rotate upward, and the outer turntable 604 is driven to form an inclined angle with the base plate 6, and the turntable 604 forms an inclined angle with the fixed frame 605. At this time, when the water flows through the scraper 606 on the outside of the fixed frame 605, the resistance encountered is small, and the water flows faster, which can improve the efficiency of power generation and avoid protecting the rotating shaft from being impacted by the water flow for a long time, which can easily cause deviation, reduce the rotation speed, and reduce the power generation.

[0030] Example 2

[0031] like Figure 3 to Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer side of the spiral volute 1 is fixedly connected with an upper cover plate 2, the top of the upper cover plate 2 is provided with a slide groove, the inner part of the slide groove of the upper cover plate 2 is slidably connected with a sliding block 202, the bottom end of the sliding block 202 is fixedly connected with a sliding sheet 201, the sliding sheet 201 slides inside the upper cover plate 2, the bottom end of the sliding sheet 201 is tightly provided with a bottom plate 203, the inner center position of the upper cover plate 2 is fixedly connected with a connecting shaft 204, the bottom end of the connecting shaft 204 is fixedly connected with a steering shaft 205, the bottom of the steering shaft 205 is fixedly connected with an extension rod 206, a fixed block 601, a rotating arm 602, a rotating rod 603 and a turntable 604 is arranged into four groups, which can protect the spiral volute 1 and are evenly arranged at the top of the base plate 6. The bottom end of the bottom plate 203 is tightly set with the outer shell 3, and the interior of the outer shell 3 is arranged as a cavity. The interior of the cavity of the outer shell 3 is fitted with a magnetic block 303. The extension rod 206 passes through the interior of the cavity of the outer shell 3 and is fixedly connected to the rotor 301. The bottom end of the rotor 301 is rotatably connected to the stator 302, and the stator 302 and the magnetic block 303 are magnetically connected. The bottom end of the extension rod 206 is fixedly connected to the extension rod 401, and the extension rod 401 is connected to the motor 4. The top of the collector 501 is arranged to be inclined. When used outdoors, it can prevent rain from damaging the collector 501.

[0032] In this embodiment, the connecting shaft 204 at the center position inside the upper cover plate 2 is rotated. At this time, the connecting shaft 204 drives the steering shaft 205 to rotate. At this time, the steering shaft 205 drives the extension rod 206 inside the outer shell 3 to rotate. The extension rod 206 drives the rotor 301 and the stator 302 inside the outer shell 3 to rotate, and rotates with the magnetic block 303 inside the outer shell 3. At this time, electricity is generated inside the outer shell 3. At this time, the electricity enters the collector 501 through the transmission line 5 to complete the electricity recovery.

[0033] The working principle of this utility model:

[0034] First, the staff installs the spiral volute 1 at the place where the water flow is the largest on the dam. The water flows through the inside of the spiral volute 1, and the water flow becomes a vortex. The base plate 6 is installed on the outside of the spiral volute 1 to adjust the water flow. When water enters the base plate 6, the piston 607 is controlled to slide upward inside the sleeve 608. When the sleeve 608 slides upward, the sleeve 608 drives the rotating rod 603 to rotate upward, and the outer turntable 604 is driven to form an inclined angle with the base plate 6, and the turntable 604 forms an inclined angle with the fixed frame 605. At this time, when the water flows through the scraper 606 outside the fixed frame 605, the resistance is small. As a result, the water flow is faster, which can improve the efficiency of power generation. When the water flow needs to be reduced, the sleeve 608 slides downward along the piston 607. At this time, the rotating rod 603 on the outside of the fixed block 601 rotates downward, and the scraper 606 blocks the water flow, thereby reducing the speed of the water flow. At this time, the flow reduction in the first stage of hydropower generation is completed, and the slide 201 at the bottom end of the upper cover plate 2 is rushed. The slide 201 slides in the slide groove inside the upper cover plate 2 driven by the top sliding block 202. At this time, the water flow rushes the slide 201 open and is inclined to the bottom plate 203. When the slide 201 is tilted at a higher degree, the water flow impacts the slide 201 faster.

[0035] When the second stage of hydropower generation needs to reduce the flow, when the water flow drives the connecting shaft 204 at the center position inside the upper cover plate 2 to rotate, the connecting shaft 204 drives the steering shaft 205 to rotate, and the steering shaft 205 drives the extension rod 206 inside the outer shell 3 to rotate, and the extension rod 206 drives the rotor 301 and the stator 302 inside the outer shell 3 to rotate, and rotates with the magnetic block 303 inside the outer shell 3. At this time, electricity is generated inside the outer shell 3, and at this time, the electricity enters the collector 501 through the transmission line 5 to complete the electricity recovery.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
