Description

Technical Field

[0001] This application relates to the field of hydropower technology, and in particular to hydropower generation devices. Background Technology

[0002] Hydropower generation utilizes the potential energy of water flowing from higher elevations, such as rivers and lakes, to lower elevations. This potential energy is converted into the kinetic energy of a turbine, which then powers a generator to produce electricity. In essence, hydropower uses water power (with head) to drive a water turbine, converting water energy into mechanical energy. If another machine (a generator) is connected to the turbine, electricity is generated as the turbine rotates, thus converting mechanical energy back into electrical energy. Hydropower generation, in a sense, is the process of converting the potential and kinetic energy of water into mechanical energy, and then into electrical energy.

[0003] However, in the process of converting water flow energy into mechanical energy for power generation, there is a lot of suspended debris in the water flow. This debris can easily become entangled and attached to the mechanical structure during the flow, causing the transmission structure to fail due to the twisting of the debris. This damages the transmission structure and makes it difficult to clean, which also limits the conversion efficiency of water energy. Summary of the Invention

A booster is installed at the inlet end of each liquid-absorbing tube; The blade assembly includes multiple sets, which are spaced apart along the length of the main tube and located on the outer wall of the main tube at positions corresponding to the clearance holes. They can rotate around the axis of the main tube, and the blade assembly and the booster are arranged one-to-one. The transmission component, located at the clearance hole, is used to transmit the rotational power of the blade assembly to the booster, thereby propelling the fluid to flow towards the outlet end of the phloem.

The rack is set inside the guide seat and slides in cooperation with the inner wall of the guide seat; The return spring is located inside the guide seat, with one end abutting against the inner wall of the guide seat and the other end abutting against the end of the rack.

Detailed Implementation

[0019] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The following is combined Figures 1-6 This describes the hydroelectric power generation device provided in the embodiments of this application.

[0021] Reference Figures 1-6 As shown, the water flow power generation device provided in this application embodiment is used to be deployed in rivers or open channels. Water flowing into the device is accelerated and pressurized after entering the device. The device includes a main tube 100, a blade assembly, a condensate drain pipe 200, a booster 300, a transmission assembly 400, and a generator 740. The main tube 100, blade assembly, and condensate drain pipe 200 are made of a material with a density less than or equal to that of water, such as PVC or a polymer material, so that the device can be suspended in water.

[0022] The main tube 100 has several liquid passage holes 110 on its side wall. Water enters the inner cavity of the main tube 100 through the liquid passage holes 110, while preventing debris in the water from entering the inner cavity of the main tube 100, thus preventing debris from getting tangled on the condensate drain pipe 200 and the propulsion component 300. The main tube 100 also has clearance holes 120 on its side wall. The blade assembly is installed on the outer wall of the main tube 100 at the position corresponding to the clearance holes 120. Under the impact of the water flow, the blade assembly can rotate around the axis of the main tube 100. The condensate drain pipe 200 is disposed in the inner cavity of the main tube 100, and the condensate drain pipe 200 has an inlet end and an outlet end that are arranged opposite each other. A booster 300 is rotatably mounted on the inlet end of the phreatic tube 200. The booster 300 includes a cylinder 310 rotatably mounted on the inlet end of the phreatic tube 200 and blades 320 distributed on the inner wall of the cylinder 310. The rotation of the cylinder 310 drives the blades 320 to rotate, thereby propelling the water flow to accelerate towards the outlet end and increasing the water pressure. A transmission assembly 400 is disposed at the clearance hole 120. The transmission assembly 400 is used to transmit the rotational power of the blade assembly to the booster 300, causing the booster 300 to push the fluid towards the outlet end of the phreatic tube 200.

[0023] The generator 740 is installed at the tail end of the main tube 100, and the generator impeller is positioned opposite the outlet end of the condensate drain pipe 200. The high-speed, high-pressure water jet ejected from the outlet end of the condensate drain pipe 200 impacts the generator impeller, thereby generating hydroelectric power.

[0024] By utilizing the technical solution provided in the above embodiments, by opening a liquid passage hole on the main pipe, it is possible to prevent debris in the water from entering the inner cavity of the main pipe and to prevent debris from getting tangled on the booster component at the liquid inlet end of the condensate drain pipe 200. The water flow drives the blade assembly to rotate, thereby driving the booster component 300 at the liquid inlet end of the condensate drain pipe 200 to rotate. By utilizing the transmission ratio between the blade assembly and the booster component 300, the rotational speed of the booster component 300 is increased, thereby accelerating and pressurizing the water flow entering the condensate drain pipe 200, increasing the kinetic energy of the water flow flowing out from the liquid outlet end of the condensate drain pipe 200, which is beneficial to improving the conversion efficiency of the water flow's kinetic energy into mechanical energy and improving the efficiency of hydropower generation.

[0025] In some specific embodiments, the booster 300 may be a shaftless hydraulic impeller, an Archimedes' screw, or a horizontal shaft helical blade. The transmission assembly 400 may be a gear transmission structure.

[0026] Reference Figure 4As shown, in some embodiments of this application, the liquid-repellent tube 200 includes multiple tubes, which are evenly arranged circumferentially within the inner cavity of the main tube 100. For example, there are six liquid-repellent tubes 200, which are evenly installed circumferentially within the inner cavity of the main tube 100. Each liquid-repellent tube 200 has a booster 300 installed at its inlet end. In this way, the outlet ends of multiple liquid-repellent tubes 200 can simultaneously output high-speed, high-pressure water flow. Generally, the high-speed, high-pressure water flow hits the impeller, thereby converting the kinetic energy of the water flow into the mechanical energy of the impeller rotation. Thus, the high-speed, high-pressure water flow that is evenly sprayed circumferentially impacts the impeller evenly, which can prevent the impeller from being biased to one side, thereby maintaining a constant output efficiency and protecting the impeller structure from damage due to asymmetrical force.

[0027] Reference Figure 2 , Figure 3 , Figure 4 As shown, in some embodiments of this application, the blade assembly includes multiple sets spaced apart along the length of the main tube 100, with each blade assembly corresponding to a propeller 300. Specifically, the liquid-repellent tubes 200 have different lengths, and an end plate is installed at the end of the main tube 100. Limiting holes are evenly opened circumferentially on the end plate, and the liquid outlets of all the liquid-repellent tubes 200 pass through the corresponding limiting holes, thereby staggering the liquid inlet of each liquid-repellent tube 200, so that each propeller 300 corresponds to a blade assembly. In this way, each propeller is driven by a set of blade assemblies, ensuring that the propeller can maintain a high rotational speed; it can also prevent water flow from interfering with each other when multiple propellers 300 rotate; and it also ensures that each liquid inlet has sufficient water flow into the liquid-repellent tube 200.

[0028] Reference Figure 5 , Figure 6 As shown, in some embodiments of this application, each blade assembly includes a ring seat 510 and a blade 520. The ring seat 510 is fitted onto the main body tube 100 at a position corresponding to the clearance hole 120, and the inner wall of the ring seat 510 is rotatably engaged with the outer wall of the main body tube 100. The blades 520 are uniformly mounted on the ring seat 510 circumferentially, and the blades 520 can drive the ring seat 510 to rotate under the impact of the fluid. The ring seat 510 transmits the rotational power to the booster 300 through the transmission assembly 400.

[0029] Reference Figure 8As shown, in some specific embodiments, the transmission assembly 400 includes a support 410, an intermediate gear 420, a first chain 430, and a second chain 440. The support 410 is fixed to the inner wall of the main tube 100. A through hole is formed on the support 410, and the inner wall of the through hole rotatably engages with the outer wall of the cylinder 310 of the booster 300, thus allowing the booster 300 to be fixed to the support 410 without affecting its rotation. The support 410 also forms a channel communicating with the through hole. The intermediate gear 420 is mounted in the channel of the support 410 via an axle and is capable of rotation. The first chain 430 is fixedly wound around the inner ring wall of the ring seat 510 and meshes with the outer teeth of the intermediate gear 420; the second chain 440 is fixedly wound around the outer wall of the booster 300 and meshes with the outer teeth of the intermediate gear 420. The diameter of the first chain 430 is larger than the diameter of the second chain 440. Thus, when the fluid impacts the impeller 520 and drives the ring seat 510 to rotate, the first chain 430 on the inner wall of the ring seat 510 meshes with the intermediate gear 420, driving the intermediate gear 420 to rotate. Then, the other side of the intermediate gear 420 meshes with the second chain 440, driving the booster 300 to rotate (for example, driving the liquid wheel to rotate). By utilizing the transmission ratio between the impeller assembly and the booster 300 (for example, the transmission ratio between the ring seat 510 and the booster 300 is 1:10 or 1:20), the rotational speed of the booster 300 is increased, thereby accelerating and pressurizing the water flow entering the condensate drain pipe 200.

[0030] Reference Figure 6 As shown, in some specific embodiments, a first spring plate 610 and a second spring plate 620 are provided between the blade and the ring seat. One end of the first spring plate 610 is mounted on the blade 520, and one end of the second spring plate 620 is mounted on the ring seat 510. The first spring plate 610 and the second spring plate 620 abut against each other to form an arc shape that bends in opposite directions. When the water flow velocity is too high, the blade 520 pushes the first spring plate 610 and the second spring plate 620 backward. The first spring plate 610 and the second spring plate 620 deform and slide against each other at the contact surface, thereby reducing the deployment angle of the blade 520 and the water-facing area, preventing input overload and achieving device self-protection. When the water flow velocity returns to normal, the elastic force of the first spring plate 610 and the second spring plate 620 will push the blade 520 back to its original position, increasing the deployment angle and the water-facing area to maintain a constant output speed. Meanwhile, when the blade 520 has a large unfolding angle, the garbage in the water will be hooked onto the blade 520; when the blade 520 has a small unfolding angle, the garbage in the water can be washed away by the water flow, preventing the garbage from accumulating on the blade 520 or the main tube 100.

[0031] Reference Figure 5As shown, in some specific embodiments, a guide seat 640, a rack 650, a return spring 660, and a synchronizing gear 670 are provided between the blade and the ring seat. The guide seat 640 is mounted on the ring seat 510. The rack 650 and the return spring 660 are both disposed inside the guide seat 640. The two sides of the rack 650 slide against the inner wall of the guide seat 640. One end of the return spring 660 is fixed to the inner wall of the guide seat 640, and the other end abuts against the end of the rack 650. The synchronizing gear 670 is sleeved on a pin. The synchronizing gear 670 rotates to drive the rack to move along the inner wall of the guide seat 640, thereby compressing the return spring 660 or causing the return spring 660 to return to its original position. When the water flow velocity is too high, the blade 520 rotates backward, driving the pin shaft and synchronous gear 670 to rotate. The synchronous gear meshes with the rack 650, causing the rack to move along the inner wall of the guide seat 640 and compress the return spring 660. This reduces the deployment angle of the blade 520 and the water-facing area, preventing input overload and achieving device self-protection. When the water flow velocity returns to normal, the elastic force of the return spring 660 pushes the rack 650 to move along the inner wall of the guide seat 640. The rack 650 meshes with the synchronous gear 670, causing the blade 520 to rotate back to its original position, increasing the deployment angle and water-facing area to maintain a constant output speed. Simultaneously, when the blade 520's deployment angle is large, debris in the water gets caught on the blade 520; when the blade 520's deployment angle decreases, the debris can be washed away by the water flow, preventing debris from accumulating on the blade 520 or the main tube 100.

[0032] In some specific embodiments, the blades are made of elastic materials. Through fiber layup design, these elastic materials achieve a "bending-torsional coupling effect," meaning the blades can adaptively adjust their pitch angle under stress, optimizing hydrodynamic performance. For example, the blades may use fiber-reinforced composite materials (such as carbon fiber, aramid fiber, glass fiber, etc.). Thus, when the water flow velocity is too high, the blades 520 bend backward due to their elasticity to reduce their deployment angle and water-facing area, preventing input overload and achieving device self-protection. When the water flow velocity returns to normal, the blades 520 automatically reset due to their elasticity, restoring their deployment angle and increasing their water-facing area to maintain a constant output speed. Simultaneously, when the blades 520 have a large deployment angle, debris in the water can be hooked onto them; when the blades 520 have a smaller deployment angle, debris can be washed away by the water flow, preventing debris accumulation on the blades 520 or the main tube 100.

[0033] Reference Figure 1As shown, in some specific embodiments, a sealing cover 630 is also installed at the connection between the blade 520 and the ring seat 510. The sealing cover 630 is made of a soft material, such as rubber. The sealing cover 630 covers the connection between the blade 520 and the ring seat 510, and the elastic component is placed inside the sealing cover 630. In this way, water and impurities in the water can prevent damage to the structure connecting the blade 520 and the ring seat 510, and it is beneficial to maintain the elastic resistance of the elastic component to the blade 520.

[0034] In some specific embodiments, the sealing cover 630 is an annular cover fitted onto the main tube 100. By designing the sealing cover 630 as an annular shape, the resistance generated during the rotation of the sealing cover 630 with the ring seat 510 can be reduced.

[0035] Reference Figure 1 As shown, in some embodiments provided in this application, the device further includes a float 710, a connecting arm 720, and an anchor cable 730. The float 710 has a density less than that of the fluid, and is made of materials such as PVC, polymers, or air cylinders to enable it to float on the water surface. The upper end of the connecting arm 720 is connected to the float 710, and the lower end of the connecting arm 720 is connected to the main pipe 100, thereby preventing the main pipe 100 from sinking. The anchor cable 730 includes at least two cables, at least one of which is connected to the float 710, and at least the other is connected to the tail end of the main pipe 100. The free ends of the anchor cables 730 are fixed to both sides of the river channel or to piles at the bottom of the river channel, thereby limiting the position of the main pipe 100 and preventing it from shifting.

[0036] Reference Figure 7 As shown, in some specific embodiments, a scraper 810 is provided on the flow-facing surface of the connecting arm 720, and the scraper 810 can move along the length direction of the connecting arm 720. Specifically, a cavity is formed inside the connecting arm 720, and a slot communicating with the cavity is opened on the flow-facing surface of the connecting arm 720. Two drive wheels 820 are installed in the cavity, and a drive chain 830 is sleeved on the two drive wheels 820. Multiple scrapers 810 are spaced apart on the drive chain 830, and the ends of the scrapers 810 located on the flow-facing surface can extend outside the slot. The drive wheels 820 drive the drive chain 830 to rotate, thereby driving the scrapers 810 to circulate back and forth along the length direction of the connecting arm 720. In this way, when the scraper 810 moves to the slot, it can capture the garbage in the water in time, and at the same time carry the captured garbage to the lower end of the connecting arm 720 and be washed away by the water flow, thereby preventing the garbage in the water from accumulating on the flow-facing surface of the device.

[0037] Reference Figure 1As shown, in some embodiments provided in this application, the main body pipe 100 includes multiple segments, and adjacent segments of the main body pipe 100 are axially connected by a flexible hose 900. In this way, when the water flow impact is large, the flexible hose 900 can offset the impact force of the water flow on the main body pipe 100 through deformation, preventing the main body pipe 100 from breaking due to local stress concentration.

[0038] The working principle of the hydroelectric power generation device in this application is as follows: When the fluid impacts the impeller 520, causing the ring seat 510 to rotate, the first chain 430 on the inner wall of the ring seat 510 meshes with the intermediate gear 420, causing the intermediate gear 420 to rotate. Then, the other side of the intermediate gear 420 meshes with the second chain 440, causing the booster 300 to rotate (e.g., causing the liquid impeller to rotate). Utilizing the transmission ratio between the impeller assembly and the booster 300 (e.g., a transmission ratio of 1:10 or 1:20 between the ring seat 510 and the booster 300), the rotational speed of the booster 300 is increased, thus accelerating and pressurizing the water flow entering the condensate drain pipe 200. In this way, the high-speed, high-pressure water flow uniformly ejected from the multiple circumferentially arranged condensate drain pipes 200 will evenly impact the impeller, preventing the impeller from being biased to one side, thereby maintaining a constant output efficiency and protecting the impeller structure from damage due to asymmetrical force.
