Description

Technical Field

[0001] This utility model belongs to the field of hydropower equipment, and in particular relates to a hydropower generation device that utilizes the gravity of water flow for driving and enhances efficiency through the series connection of multiple power units. Background Technology

[0002] Traditional hydropower relies heavily on water conservancy facilities with large drops and large flows (such as large hydropower stations), but it does not make sufficient use of dispersed water flows with small drops, such as urban building wastewater, small waterfalls, and urban groundwater, resulting in resource waste. In addition, traditional equipment has a complex structure and high cost, making it unsuitable for small-scale, decentralized power generation scenarios. Utility Model Content

[0003] This utility model aims to provide a modular design, stable power, and flexibly expandable water flow power generation device. When water flows downward, it can be intercepted multiple times and generated by mechanical drive. Through independently packaged power units and series structure, it can efficiently utilize dispersed small drop water flow (such as building wastewater), improve power generation efficiency and adaptability, realize efficient use of water resources, and reduce power generation costs.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A water flow power generation device includes a water supply unit, at least one power unit, and a power generation unit;

[0006] The water supply unit includes a water tank, and the water tank is equipped with an inlet pipe for introducing water flow;

[0007] Each of the aforementioned power units is housed within an outer casing and includes a conveyor belt, multiple water hoppers, and rotating wheels at the top and bottom ends; the water hoppers are evenly distributed and fixed on the conveyor belt, and the rotating wheels at the top and bottom ends form a closed-loop structure with the conveyor belt; the outer casing is provided with a water outlet;

[0008] The power generation unit is a generator; in the case of a single power unit, the generator is connected to the rotating wheel of the power unit through a drive shaft; in the case of multiple power units, the rotating wheels of each power unit are connected in series through a drive shaft, and the generator is connected to the drive shaft after the series connection.

[0009] Furthermore, the water inlet pipe is equipped with a switch, and the water outlet of the water inlet pipe is set to correspond to the water hopper on the conveyor belt.

[0010] Furthermore, the rotating wheel is engaged with the conveyor belt.

[0011] Furthermore, the water flow is building wastewater, large or small waterfall water, or urban groundwater, and the introduction and discharge of the water flow do not change the original water discharge path.

[0012] Furthermore, when multiple power units are connected in series, the rotating wheel of each power unit is the lower rotating wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Modular design, flexible expansion: Each power unit is independently packaged, and multiple power units can be connected in series through a drive shaft to stack power, adapting to different flow / power requirements (such as a single unit for a single household, or multiple units connected in series for a community).

[0015] 2. Stable power: The water bucket is fixed on the conveyor belt, forming a closed-loop transmission with the upper and lower rotating wheels, which avoids slippage, ensures stable power transmission, and improves power generation efficiency;

[0016] 3. Compact structure: Each power unit is housed within the outer casing, reducing space occupation and facilitating installation in confined areas such as buildings and near pipelines;

[0017] 4. Highly efficient resource utilization: It can utilize dispersed water flows with small drops (such as building wastewater) to generate electricity, realizing "wastewater energy conversion," which is energy-saving and environmentally friendly;

[0018] 5. This device is suitable for various water flow types, including building wastewater, large and small waterfalls, and urban groundwater. Furthermore, its power generation efficiency is positively correlated with the water flow rate: on the one hand, the larger the waterfall flow and the greater the building drainage volume, the more water a single or series-connected power unit can handle through its water hopper, resulting in a stronger gravity-driven conveyor belt output; on the other hand, by flexibly increasing the number of power units connected in series, it can further adapt to larger water flow rates, thereby significantly improving the overall power generation and achieving the advantages of flow rate adaptation and adjustable power.

[0028] The present invention relates to a water flow power generation device, characterized in that:

[0029] Includes a water supply unit 1, at least one power unit 2, and a power generation unit 3:

[0030] The water supply unit 1 includes a water tank, which is equipped with an inlet pipe 11 (with a switch 12) for introducing water flow (such as building wastewater, large and small waterfall water, etc., which can be intercepted and installed). The outlet of the inlet pipe 11 is set to correspond to the water tank of the power unit 2.

[0031] Each power unit 2 is independently placed inside the outer casing 4, including a conveyor belt 21, multiple water hoppers 22, and rotating wheels 23 at the upper and lower ends; the water hoppers 22 are evenly distributed and fixed on the conveyor belt 21, and the upper and lower rotating wheels 23 mesh with the conveyor belt 21 to form a closed loop structure (the conveyor belt circulates according to the gravity difference of the water hoppers, and the upper and lower rotating wheels support and guide the transmission); the bottom of the outer casing 4 is provided with a water outlet 41 for discharging the water poured out of the water hoppers;

[0032] The power generation unit 3 is a generator; if it is a single power unit, the generator 3 is connected to the rotating wheel 23 (preferably the lower rotating wheel) of the power unit through the transmission shaft 51; if it is multiple power units, the rotating wheels 23 (preferably the lower rotating wheels on the same side) of each power unit are connected in series through the transmission shaft 52, and the generator is connected to the transmission shaft after being connected in series; after the water flows into the water hopper, gravity drives the conveyor belt to move in a circular motion along the upper and lower rotating wheels, driving the rotating wheels to rotate, and the transmission shaft transmits the power of the single or multiple power units to the generator to generate electricity.

[0033] Example 1: Power generation device of a single power unit

[0034] The water supply unit is a 50L water tank with a manual switch on the bottom inlet pipe and the outlet is aligned with the water hopper above the power unit. The power unit is housed in an outer casing measuring 60cm long, 30cm wide, and 80cm high, and includes a circular conveyor belt (1.5m in circumference), eight water hoppers (each with a capacity of 5L, evenly fixed on the conveyor belt at 18cm intervals), and two rotating wheels (20cm in diameter, meshing with the teeth on the inner side of the conveyor belt). An outlet (connected to the sewer) is located at the bottom of the outer casing corresponding to the lower end of the conveyor belt. The drive shaft (2cm in diameter) at the center of the lower rotating wheel extends out of the outer casing and connects to a 100W generator.

[0035] Working process: When the water inlet pipe is turned on, water flows into the water hopper above the conveyor belt. After the water hopper is filled with water, it moves downward due to gravity, driving the conveyor belt to circulate clockwise along the upper and lower rotating wheels (speed 0.3m / s). The lower rotating wheel rotates with the conveyor belt, driving the generator to generate electricity through the drive shaft. When the water hopper moves to the lower rotating wheel, it tilts with the direction of the conveyor belt, and the water is discharged through the water outlet of the outer casing. The empty water hopper circulates with the conveyor belt to the top to fill with water again, realizing continuous operation.

[0036] Application scenario: Wastewater from the balcony of a single residential building (such as washing and rinsing water) can generate electricity to meet the needs of mobile phone charging, night light power supply, etc.

[0037] Example 2: A power generation device consisting of three power units connected in series (multiple power units can be installed in series, increasing torque and enabling the driving of large generators).

[0038] The water supply unit is a 150L water collection tank, which branches into three water inlet pipes with switches through a three-way pipe, each corresponding to one of the three power units. The structure of each power unit is the same as in Example 1 (the outer casing size is the same, and the water tank capacity is 5L). The lower rotating wheels of the three power units are connected in series through the same drive shaft (diameter 3cm) (the drive shaft passes through each outer casing in sequence and is fixed to the rotating wheel). A 300W generator is connected to the end of the drive shaft.

[0039] Working process: Open the switches of each water inlet pipe, and the water flow is injected into the water tanks of the three power units. The conveyor belt of each unit independently drives the lower rotating wheel to rotate. The series transmission shafts superimpose the power of the three units (the total power is about 3 times that of a single unit) to drive the generator to generate electricity efficiently. The water discharged from each unit is collected through the outer casing outlet and discharged into the municipal sewer.

[0040] Application scenarios: Centralized wastewater (such as kitchen and bathroom wastewater) generation in multi-story apartment buildings can be used for corridor lighting, emergency power supply for elevators, etc.

[0041] In summary, the water flow utilized by this device covers building wastewater, large and small waterfall water, and urban groundwater, and the power generation is directly related to the water flow rate: taking building wastewater as an example, when the concentrated water use by residents leads to an increase in drainage volume, the water tank can be filled with water more frequently, the conveyor belt circulation speed is accelerated, the power unit output power is increased, and the generator power generation increases simultaneously.

[0042] For waterfalls, small waterfalls can generate basic electricity using a single power unit, while large waterfalls can be powered by multiple power units connected in series, utilizing the gravity of a larger volume of water to exponentially increase the total power output and ultimately achieve a significant increase in power generation. This effectively adapts to the power generation needs of different flow scenarios, such as... Figure 4 The waterfall interception power generation device shown is for Dashan Waterfall, and mainly includes waterfall interception water tank 100, water tank 200 and power generation unit 300.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
