A roller type flapping wing water-pushing and oxygen-renewing device based on belt-rope transmission

Abstract

A roller-type flapping-wing water-pushing and reoxygenating device based on belt-rope transmission is disclosed. By controlling the forward and reverse rotation of the motor power mechanism, and then converting the rotational motion into linear reciprocating motion through the belt-rope transmission mechanism, the roller-type flapping wing actuator achieves rolling reciprocating oscillation. Based on the design of adjustable tilt angle blocks, the roller-type flapping wing can maintain the optimal pushing angle during water-pushing operations under the interaction of traction force, water flow resistance, track support force, and flapping wing tilt angle blocks, achieving directional and efficient water pushing. The rope-driven tension traction method can easily adapt to different river width requirements, and the application point of the traction force on the wing plate can be flexibly selected to ensure the optimal application point of the driving force, resulting in higher operating efficiency and better adaptability. Compared with traditional water-pushing and reoxygenating devices, this invention has higher energy conversion efficiency, water pushing efficiency, reliability, and environmental adaptability, enabling efficient and environmentally friendly water flow control.

Description

Technical Field

[0001] This invention belongs to the fields of plain river network water management, aquaculture, and water flow control, and particularly relates to a flapping-wing motion water-pushing and reoxygenating device. Background Technology

[0002] The plain river network is characterized by gentle slopes, low flow velocities, and insufficient self-purification capacity, leading to prominent problems such as excessive algae growth, sludge accumulation, and black and foul-smelling water, severely impacting residents' quality of life and health. To improve the water quality, hydrodynamics, and ecology of the river network, methods such as widening and dredging the main channels, constructing relay pumping stations, and combining pumps and sluices have played a positive role in enhancing the hydrodynamic performance of the plain river network. However, because the pumping head in plain river channels is almost zero, traditional axial flow pumps suffer from high energy consumption, high noise, poor stability, and severe cavitation, making it difficult to meet the demands for low-head, high-flow, and efficient water delivery.

[0003] In the aquaculture industry, with its rapid development, efficient and environmentally friendly aquaculture technologies have become an important direction for industry development. Raceway fish farming, as an intensive and ecological aquaculture method, has been widely used around the world. This model increases dissolved oxygen levels in the water through circulating water flow, reducing disease incidence and increasing fish growth rates. However, the water fluctuations, disturbances, noise, and vibrations caused by aeration and water propulsion can lead to stress responses in fish, affecting their growth, behavior, and health. Furthermore, the hydrodynamic force generated by aeration and water propulsion is insufficient to meet the self-purification capacity requirements of the raceway water, cannot be precisely controlled, and has high energy consumption.

[0004] In the field of water flow control, traditional water propulsion devices often suffer from high energy consumption, low efficiency, poor environmental adaptability, and low reliability. With increasing environmental awareness and technological advancements, the market demand for efficient, environmentally friendly, reliable, and flexible water flow control devices is growing. Rope-driven roller-type flapping-wing water propulsion devices, with their high flexibility, high reliability, low energy consumption, and environmental friendliness, demonstrate enormous potential in the field of water flow control. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a roller-type flapping wing water propulsion and reoxygenation device based on belt-rope transmission. It aims to replace sliding with rolling and generate continuous and stable power through the stretching and traction motion of flexible ropes, so as to promote water flow in an efficient and environmentally friendly manner, improve the hydrodynamics and dissolved oxygen content of the water, improve the reliability, efficiency and adaptability of the water propulsion device, and generate continuous propulsion power.

[0011] In this invention, by controlling the forward and reverse rotation of the motor power mechanism C, power is transmitted to the roller-type flapping wing actuator D via the belt-rope transmission mechanism B, converting rotational motion into linear reciprocating traction motion of the rope. The upper, lower, left, and right rollers of the roller-type flapping wing actuator D are constrained and cooperate with the roller tracks of the support mechanism A in the vertical and horizontal directions. Under the reciprocating traction of the rope, they reciprocate along the roller tracks of the support mechanism A, realizing rolling friction instead of sliding friction, significantly reducing frictional resistance and additional energy consumption. In this invention, flapping wing tilting angle blocks are arranged on the lower roller support frame 95 and the upper roller support frame 96 of the flapping wing. Under the interaction of traction force and water flow resistance, the roller-type flapping wing can maintain the optimal pushing angle during water pushing operations, achieving directional and efficient water pushing. In this invention, the belt-driven transmission method based on pulleys ensures better overload protection and improves the overall operational reliability of the device. In this invention, the rope-based tension traction method can adapt to different river width requirements. With the basic motion principle unchanged, product solutions can be quickly formed simply by modifying the track parameters. Meanwhile, based on the rope-based tensioning and traction method, the point of application of traction force on the wing plate can be flexibly selected to ensure that the driving force has the best point of application, resulting in higher operating efficiency and better adaptability.

[0012] The beneficial effects of this invention are as follows: compared with existing water-pushing and reoxygenating devices, this invention has better reliability, environmental adaptability, and higher energy transfer and conversion efficiency. Attached Figure Description
