Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy power generation, in particular to a power generation device adapted to riverbed distribution. Background Art

[0002] Due to the geographical characteristics of my country, which is high in the west and low in the east, most rivers flow downward from west to east. The large dam-type hydropower stations currently in use are basically only suitable for concentrated station construction in the canyon terrain with high altitudes and large drop in elevation in the west. However, the central and eastern parts of my country, which are more vast and have the largest demand for electricity, are mostly hilly and plain areas with gentle terrain, which are basically not suitable for high-altitude water storage and dam construction for power generation.

[0003] Therefore, there is a widespread demand for a riverbed distributed power generation device that uses the natural water flow of a gentle river to generate electricity. Existing similar riverbed power generation systems need to maintain a certain water level for the stability of power generation. Therefore, a water channel dedicated to power generation is usually set up on the side of the river, and a water wheel is installed in the water channel to drive the water wheel to generate electricity through the water flow. If a fixed-height water wheel is used for the riverbed, it cannot be adjusted according to the water level. When the water level is too high or too low, normal power generation cannot be guaranteed.

[0004] In order to solve the current technical problems, the main purpose of the utility model is to provide a power generation device that is adapted to the distribution of the riverbed. This power generation device can well adapt to the adaptive power generation under the change of riverbed water level, and can realize automatic height adjustment according to the water level, thereby ensuring that the waterwheel can always be at the optimal power generation height, ensuring the stability of power generation and improving the power generation efficiency.

[0005] In order to realize the above-mentioned technical features, the purpose of the utility model is achieved as follows: a power generation device adapted to riverbed distribution, comprising a base fixedly connected to the riverbed, a column is arranged on the top of the base, a float is arranged on the outside of the column through a sliding sleeve, a lifting sleeve is fixed on the top of the float for sliding cooperation with the column, a main shaft seat and a generator mounting seat are symmetrically arranged on both sides of the top of the lifting sleeve; a waterwheel device driven by water flow is rotatably supported between the main shaft seats on both sides; the waterwheel main shaft of the waterwheel device is connected to a transmission, the transmission is connected to a generator through a transmission belt, the generator is fixed on the generator mounting seat on the corresponding side, and the generator is connected to the battery through a first wire.

[0006] The outer wall of the column is provided with upright guide ribs, the center of the lifting sleeve is provided with a center hole, and the inner wall of the center hole is provided with guide grooves for matching with the guide ribs.

[0007] The number of the guide ribs is at least one group.

[0008] The waterwheel device comprises a waterwheel main shaft rotatably supported between main shaft seats, a plurality of impeller rods evenly arranged in a circumference are fixedly mounted on the middle part of the waterwheel main shaft through a mounting seat, and waterwheel blades are fixed on the ends of the impeller rods.

[0009] The storage battery is connected to the remote power-consuming device via a second electric wire.

[0010] Multiple groups of power generation devices are arranged in sequence along the water flow direction of the riverbed.

[0011] The utility model has the following beneficial effects:

[0012] 1. The power generation device of the utility model can well adapt to the adaptive power generation under the change of riverbed water level, and can realize automatic height adjustment according to the water level, thereby ensuring that the waterwheel can always be at the optimal power generation height, ensuring the stability of power generation and improving power generation efficiency.

[0013] 2. Renewable energy: The riverbed distributed power generation device utilizes the kinetic energy of river water flow. It is a renewable energy source that does not produce greenhouse gases and other pollutants and is environmentally friendly.

[0014] 3. Distributed power generation: The utility model device can be installed at multiple points along the river bank to achieve distributed power generation, reduce dependence on centralized energy supply, and improve the reliability of energy supply. It avoids the large-scale engineering investment of building dams on high-level canyons. It directly reduces the difficulty of the project. At the same time, it also reduces the transmission construction and investment of West-East Power Transmission.

[0015] 4. Sustainability: River water flow is a continuous resource. Compared with other energy sources, such as coal, oil and other limited resources, riverbed distributed power generation devices have better sustainability.

[0016] 5. Cost-effectiveness: Compared with large-scale hydroelectric power plants, the construction and operation costs of power generation systems adapted to riverbed distribution are relatively low.

[0017] 6. Small geographical restrictions: The installation of riverbed distributed power generation devices only requires gentle river conditions, slower water flow speeds and shallower depths, so it is feasible in many areas.

[0018] 7. Small environmental impact: The installation of turbines and generators may have a certain impact on the river ecosystem, such as changing water flow and disturbing aquatic life, so environmental protection factors need to be considered during the design and installation process. Riverbed distributed power generation devices have a small impact on the environment.

[0019] 8. Small seasonal fluctuations: Even though the flow of rivers may be affected by seasonal rainfall and climatic conditions, which may cause the river surface to rise and fall, it will cause fluctuations in power generation output. However, the utility model can automatically adjust the optimal water entry depth of the horizontal axis waterwheel blades according to different water surface heights, thereby improving power generation efficiency. The power distribution and storage system will also properly balance the energy supply.

[0020] 9. Low initial investment: Not only the construction and operation and initial investment of riverbed distributed power generation devices, but also the costs of equipment procurement, installation and maintenance are relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

This power generation device can well adapt to adaptive power generation under the change of riverbed water level, and can realize automatic height adjustment according to the water level, thereby ensuring that the waterwheel can always be at the optimal power generation height, ensuring the stability of power generation, and improving power generation efficiency. During the specific operation, the entire waterwheel device is supported on the column 2 in a floating manner, so that even when the water level changes, the waterwheel device can always be in contact with the water flow, thereby achieving the purpose of stable power generation. When the water level rises, the buoy 3 will drive the lifting sleeve 4 on its top to rise along the column 2, and when the water level drops, the buoy 3 will drive the lifting sleeve 4 to drop along the column 2, so that the waterwheel device can always be driven by the water flow.

[0030] Furthermore, the outer wall of the column 2 is provided with an upright guide rib 10, the center of the lifting sleeve 4 is provided with a center hole 21, and the inner wall of the center hole 21 is provided with a guide groove 20 for matching with the guide rib 10.

With the above-mentioned structure, when the water level changes, the buoyancy will push the float 3, and then drive the lifting sleeve 4 on the top of the float 3 to achieve lifting action, and in the lifting process, the vertical lifting is always maintained.

[0031] Furthermore, the number of the guide ribs 10 is at least one group. By using at least one group of guide ribs 10, reliable rotation limiting is ensured.

The above-mentioned waterwheel device can be used to convert water flow power into power generation power.

[0033] Furthermore, the storage battery 17 is connected to the remote power-consuming device via the second electric wire 16. By using the storage battery 17, the generated electricity can be stored.

[0034] Furthermore, multiple groups of power generation devices are arranged in sequence along the direction of the water flow 18 of the riverbed 19. Through the above arrangement, the water flow power of the river can be maximized.

[0035] Furthermore, the axis of the waterwheel main shaft of the waterwheel device is arranged perpendicular to the water flow direction of the riverbed.

[0036] The specific working process and principle of this utility model:

[0037] During the specific arrangement and installation process, first, a plurality of power generation devices are arranged in sequence along the direction of the water flow 18 of the riverbed 19. During the flow of water, the waterwheel blades 5 are pushed, and the waterwheel main shaft 8 and the transmission 13 are driven by the waterwheel blades 5. The power is transmitted from the transmission belt 12 to the generator 14 through the transmission 13, and the generator 14 generates electricity. The electricity generated by the generator 14 will be stored in the battery 17 for storage; and the battery 17 will then supply the remaining electricity to the electrical equipment.
