Description

Technical Field

[0001] This invention relates to the field of hydropower technology, specifically to a hydropower wastewater power generation device. Background Technology

[0002] Hydropower is the process of converting water energy into electrical energy. It mainly utilizes the potential energy in the water body, and forms a head by concentrating the drop of the natural water flow through structures. Reservoirs are used to collect and regulate the flow of natural water to maintain stable power generation conditions. The basic equipment includes a turbine generator set. When water flows through the turbine, the turbine is driven by the water flow and rotates, which in turn drives the generator to generate electricity. In this process, the mechanical energy of the turbine is converted into electrical energy. After being processed by power transformation and transmission and distribution equipment, the electricity is finally delivered to users.

[0003] Meanwhile, current hydropower stations generate electricity through the action of water flow, and then discharge the water through downward-sloping outlets and channels. The discharged water still has considerable kinetic energy that could be utilized, but it is not being used at present, resulting in a significant waste.

[0004] Existing hydroelectric power generation equipment suffers from unstable water flow at the power station's drainage outlet. If the water flow is too large or the water level is too high, the turbine can be completely submerged, causing it to malfunction. Furthermore, the presence of floating debris can affect the turbine's rotation.

[0005] Therefore, it is essential to invent a water conservancy wastewater power generation device. Summary of the Invention

[0006] The purpose of this invention is to provide a water-powered wastewater generator to solve the problems of existing water-powered generators. When in use, the water flow at the power station's drainage outlet is unstable. If the water flow is too large or the water level is too high, the turbine will be completely submerged, causing it to malfunction. Furthermore, if there are floating objects, they will affect the rotation of the turbine.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fixed frame, guide columns, buffer springs, a drive mechanism, mounting plates, a float, a transmission mechanism, a generator, a slag removal mechanism, a drain pipe, and a diversion pipe. The fixed frame is bolted to the drain outlet of the power station, and several guide columns are fixed inside the fixed frame, each guide column being movably fitted with a buffer spring. The drive mechanism has guide columns sliding through it, and several mounting plates are bolted to its outer surface, with a float bolted to the lower surface of each mounting plate. A transmission mechanism is bolted to the upper surface of the drive mechanism, and a generator is bolted to the upper surface of the transmission mechanism. A slag removal mechanism is fixed to the other end of the transmission mechanism. The output end of the generator is connected to an external energy storage mechanism via a cable. A drain pipe is fixed to the lower surface of the drive mechanism via a connector, and a diversion pipe is fixed to the outer surface of the drain pipe via a connector. The other end of the diversion pipe is fixed to the upper outer surface of the drive mechanism via a connector.

[0008] Furthermore, the drive mechanism includes a protective shell, a fixing frame, a water inlet, a rotor, and a drain pipe. Several fixing frames are welded to the outer surface of the protective shell, with guide columns sliding through the interior of each fixing frame. A water inlet is located at one end of the protective shell, and a rotor is rotatably mounted inside the protective shell via a support bearing. The upper end of the rotor is fixed to the input end of the generator. A drain pipe is welded to the upper outer surface of the protective shell. A drain outlet is located at the lower end of the protective shell, positioned below the rotor, and a drain pipe is fixed to the drain outlet via a connector. This configuration allows the kinetic energy of the water discharged from the power station to drive the generator to rotate, and also allows excess water to be discharged.

[0009] Furthermore, one end of the drain pipe is fixed to the diversion pipe via a connector, and the lowest end of the drain pipe is flush with the middle part of the height of the protective shell. This arrangement allows excess water inside the protective shell to be guided into the drain pipe through the drain pipe and the diversion pipe.

[0010] Furthermore, the impeller includes a top plate, blades, a bottom plate, and a water outlet. The top plate is rotatably connected to the protective shell via a support bearing, and the center of the upper side of the top plate is fixed to the input end of the generator. Several blades are welded to the lower side of the top plate, and the bottom plate is welded to the lower end of the blades. The lower side of the bottom plate is rotatably connected to the protective shell via a support bearing, and a water outlet is provided through the bottom plate. The water outlet is located directly above the drain pipe. With this arrangement, the water flow will apply pressure to the blades, causing the impeller to rotate. During the rotation of the impeller, the generator will operate, and finally, the water will be discharged into the drain pipe through the water outlet.

[0011] Furthermore, the transmission mechanism includes a housing, a first bearing seat, a second bearing seat, a first transmission rod, and a second transmission rod. The housing is fixed to the upper side of the protective shell by bolts, and the first bearing seat and the second bearing seat are fixed inside the housing by bolts. The first transmission rod is rotatably mounted inside the first bearing seat via a support bearing. One end of the first transmission rod is connected to the input end of the generator through the engagement of two bevel gears. The other end of the first transmission rod is connected to the second transmission rod through the engagement of two bevel gears, and the other end of the second transmission rod is fixed to a slag removal mechanism by bolts. This arrangement allows the rotation of the generator input end to be transmitted to the slag removal mechanism.

[0012] Furthermore, the slag removal mechanism includes a positioning plate, a first rocker arm, a second rocker arm, a limiting plate, an inner cylinder, an extension column, and a support frame. The positioning plate is fixed to the second transmission rod by bolts. Several first rocker arms are hinged and rotatably mounted on the outer side of the positioning plate. A second rocker arm is hinged and rotatably mounted on the other end of the first rocker arm, and the other end of the second rocker arm is hinged and rotatably connected to the limiting plate. An inner cylinder is rotatably mounted inside the limiting plate via a support bearing. An extension column passes through the middle of the inner cylinder via a threaded engagement. One end of the extension column is fixed to the positioning plate by welding, and the other end of the extension column is rotatably connected to the support frame via a support bearing. The support frame is fixed to the drive mechanism by bolts. This arrangement can push away larger floating objects in the water flow, preventing floating objects from obstructing the operation of the device.

[0013] Furthermore, several floats are provided, and the height of each float is equal to half the height of the drive mechanism. The outer edges of the floats are rounded. This arrangement allows half of the drive mechanism to be located inside the water flow, while the remaining part floats on the water surface. This ensures the normal operation of the device regardless of changes in water flow. Furthermore, each guide post is movably fitted with two buffer springs, which are arranged on the upper and lower sides of the drive mechanism. This arrangement can limit the extreme movement position of the drive mechanism and prevent the drive mechanism from hitting the fixed frame, thereby improving the service life of the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the drive mechanism is designed such that, during use, water flowing from the power plant enters the protective shell through the inlet. Under the action of the protective shell, the water flow is guided to the impeller, causing the impeller to rotate under the action of the water flow. Finally, the water flow is discharged into the drain pipe. If the water flow is too large, the excess water will enter the drain pipe and then be discharged into the drain pipe through the diversion pipe.

[0015] In the transmission mechanism of this invention, during use, the input end of the generator rotates under the action of the drive mechanism, and then, with the cooperation of two bevel gears, drives the first transmission rod to rotate. During the rotation of the first transmission rod, with the cooperation of two other bevel gears, it drives the second transmission rod to rotate. During the rotation of the second transmission rod, it can drive the slag removal mechanism to rotate.

[0016] In this invention, the slag removal mechanism is designed such that, during use, the positioning disc rotates under the action of the second drive shaft, which in turn drives the first rocker arm, the second rocker arm, the limiting disc, the inner cylinder, and the extension column to rotate. During rotation, the first and second rocker arms push away larger floating objects in the water flow, preventing them from entering the drive mechanism. At the same time, the position of the limiting disc on the extension column can be adjusted by manually rotating the inner cylinder, thereby adjusting the range of action on the water flow.

[0017] The float configuration of this invention allows half of the drive mechanism to be located inside the water flow, while the rest floats on the water surface, thus ensuring the normal operation of the device regardless of changes in water flow.

[0018] The buffer spring in this invention limits the extreme movement position of the drive mechanism when it moves up and down along the guide post, and prevents the drive mechanism from hitting the fixed frame, thus improving the service life of the device. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] As attached Figure 1-7 As shown: This invention provides a hydroelectric power generation device using surplus water, comprising a fixed frame 1, guide columns 2, buffer springs 3, a drive mechanism 4, mounting plates 5, floats 6, a transmission mechanism 7, a generator 8, a slag removal mechanism 9, a drain pipe 10, and a diversion pipe 11. The fixed frame 1 is bolted to the drain outlet of the power station, and several guide columns 2 are fixed inside the fixed frame 1, each guide column 2 being movably fitted with a buffer spring 3. The drive mechanism 4 has guide columns 2 slidingly passing through it, and several mounting plates 5 are bolted to the outer side of the drive mechanism 4, with floats 6 bolted to the lower side of the mounting plates 5. The transmission mechanism 7 is bolted to the upper side of the drive mechanism 4, and the generator 8 is bolted to the upper side of the transmission mechanism 7, with the slag removal mechanism 9 fixed to the other end of the transmission mechanism 7. The output end of the generator 8 is connected to an external energy storage mechanism via a cable. The drain pipe 10 is fixed to the lower side of the drive mechanism 4 via a connector, and the diversion pipe 11 is fixed to the outer side of the drain pipe 10 via a connector, with the other end of the diversion pipe 11 fixed to the upper outer side of the drive mechanism 4 via a connector.

[0029] Specifically, the drive mechanism 4 includes a protective shell 41, a fixing frame 42, a water inlet 43, a rotating wheel 44, and a drain pipe 45. Several fixing frames 42 are welded to the outer surface of the protective shell 41, with guide posts 2 slidingly passing through the interior of each fixing frame 42. A water inlet 43 is provided at one end of the protective shell 41, and a rotating wheel 44 is rotatably mounted inside the protective shell 41 via a support bearing. The upper end of the rotating wheel 44 is fixed to the input end of the generator 8. A drain pipe 45 is welded to the upper outer surface of the protective shell 41. The lower end of the protective shell 41... A drain outlet is provided, which is located on the lower side of the impeller 44 and is fixed to a drain pipe 10 via a connector. During use, the water flow from the power station enters the protective shell 41 through the inlet 43. Under the action of the protective shell 41, the water flow is guided to the impeller 44, causing the impeller 44 to rotate under the action of the water flow. Finally, the water flow is discharged into the drain pipe 10. If the water flow is too large, the excess water will enter the drain pipe 45 and then be discharged into the drain pipe 10 through the diversion pipe 45.

[0030] Specifically, one end of the drain pipe 45 is fixed to the diversion pipe 11 via a connector, and the lowest end of the drain pipe 45 is flush with the middle part of the height of the protective shell 41. In use, excess water inside the protective shell 41 can be guided into the drain pipe 10 through the drain pipe 45 and the diversion pipe 11. As the diversion pipe 11 discharges the water, a siphon effect is generated, thereby accelerating the discharge of excess water.

[0031] Specifically, the impeller 44 includes a top plate 441, blades 442, a bottom plate 443, and a water outlet 444. The top plate 441 is rotatably connected to the protective shell 41 via a support bearing, and the center of the upper side of the top plate 441 is fixed to the input end of the generator 8. Several blades 442 are fixed to the lower side of the top plate 441 by welding, and the lower end of the blades 442 is fixed to the bottom plate 443 by welding. The lower side of the bottom plate 443 is rotatably connected to the protective shell 41 via a support bearing, and the water outlet 444 is opened through the interior of the bottom plate 443. The water outlet 444 is located directly above the drain pipe 10. When in use, the water flow will apply pressure to the blades 442, causing the impeller 44 to rotate as a whole. During the rotation of the impeller 44, the generator 8 will work, and finally the water flow will be discharged into the drain pipe 10 through the water outlet 444.

[0032] Specifically, the transmission mechanism 7 includes a housing 71, a first bearing seat 72, a second bearing seat 73, a first transmission rod 74, and a second transmission rod 75. The housing 71 is fixed to the upper side of the protective shell 41 by bolts, and the first bearing seat 72 and the second bearing seat 73 are fixed inside the housing 71 by bolts. The first transmission rod 74 is rotatably mounted inside the first bearing seat 72 by a support bearing. One end of the first transmission rod 74 is connected to the input end of the generator through the engagement of two bevel gears. The other end of the first transmission rod 74 is connected to the second transmission rod 75 through the engagement of two bevel gears. The other end of the second transmission rod 75 is fixed to a slag removal mechanism 9 by bolts. In use, the input end of the generator rotates under the action of the drive mechanism 4, and then drives the first transmission rod 74 to rotate under the engagement of the two bevel gears. During the rotation of the first transmission rod 74, the second transmission rod 75 is driven to rotate under the engagement of the other two bevel gears. During the rotation of the second transmission rod 75, the slag removal mechanism 9 can be driven to rotate.

[0033] Specifically, the slag removal mechanism 9 includes a positioning plate 91, a first rocker arm 92, a second rocker arm 93, a limiting plate 94, an inner cylinder 95, an extension column 96, and a support frame 97. The positioning plate 91 is fixed to the second transmission rod 75 by bolts. Several first rocker arms 92 are hinged and rotatably mounted on the outer side of the positioning plate 91. The other end of the first rocker arm 92 is hinged and rotatably mounted to the second rocker arm 93, and the other end of the second rocker arm 93 is hinged and rotatably connected to the limiting plate 94. The inner cylinder 95 is rotatably mounted inside the limiting plate 94 through a support bearing. The middle part of the inner cylinder 95 passes through the extension column 96 through thread engagement. One end of the extension column 96 is welded to the positioning plate 91. The expansion column 96 is fixed, with the other end rotatably connected to the support frame 97 via a support bearing. The support frame 97 is fixed to the drive mechanism 4 by bolts. In use, the positioning plate 91 can rotate under the action of the second transmission shaft 75, and then drive the first rocker arm 92, the second rocker arm 93, the limiting plate 94, the inner cylinder 95, and the expansion column 96 to rotate respectively. During the rotation, the first rocker arm 92 and the second rocker arm 93 will push away larger floating objects in the water flow to prevent floating objects from entering the drive mechanism 4. At the same time, the position of the limiting plate 94 on the expansion column 96 can be adjusted by manually rotating the inner cylinder 95, thereby adjusting the range of action on the water flow.

[0034] Specifically, there are several floats 6, and the height of the floats 6 is equal to half the height of the drive mechanism 4. The outer edge of the floats 6 is rounded. This arrangement allows half of the drive mechanism 4 to be located inside the water flow, while the rest of the drive mechanism 4 floats on the water surface, thus ensuring the normal operation of the device regardless of changes in water flow.

[0035] Specifically, two buffer springs 3 are movably sleeved on each guide post 2. These two buffer springs 3 are located on the upper and lower sides of the drive mechanism 4. When the drive mechanism 4 moves up and down along the guide post 2, the buffer springs 3 can limit the extreme movement position of the drive mechanism 4 and prevent the drive mechanism 4 from hitting the fixed frame 1, thereby improving the service life of the device.

[0036] A method of using a water conservancy wastewater power generation device according to any one of claims 1 to 8, characterized by comprising the following steps: During the preparation phase, the fixing bracket 1 is fixed to the inside of the channel at the outlet of the power plant using bolts.

[0037] In the power generation process, the kinetic energy of the water flow is converted into electrical energy through the cooperation of the drive mechanism 4 and the generator. During the slag removal process, when the drive mechanism 4 is working, it will drive the slag removal mechanism 9 to rotate through the transmission mechanism 7, pushing away larger floating objects in the water flow and preventing them from entering the drive mechanism 4.

[0038] All components used in this application are standard parts, and the specific connection methods of each part adopt conventional methods such as sewing and gluing that are mature in the prior art. All structures use conventional materials in the prior art, and will not be described in detail here.

[0039] In summary, this hydropower wastewater generation device, by incorporating a buffer spring 3, a drive mechanism 4, a float 6, a transmission mechanism 7, and a slag removal mechanism 9, addresses the problems of existing hydropower generation devices. These problems arise because the water flow at the power station's drainage outlet is unstable; excessive water flow or a high water level can completely submerge the turbine, preventing normal operation. Furthermore, the presence of floating debris can affect the turbine's rotation.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
