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 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 flapping-wing 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 flapping-wing water-propulsion device based on rope traction. It aims to generate continuous and stable power through the stretching and traction motion of flexible ropes, thereby promoting water flow in an efficient and environmentally friendly manner, improving the hydrodynamics and dissolved oxygen content of the water body, enhancing the reliability and adaptability of the water-propulsion device, and generating continuous propulsion power.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A rope-driven flapping water-pushing device includes a motor power mechanism, a pulley rope transmission mechanism, a reciprocating swing actuator, and a support mechanism. The motor power mechanism is fixed to a motor support base, which is fixed to the middle position of the upper support plate of the support mechanism. The pulley rope transmission mechanism fixes the upper support plate and the support beam of the support mechanism. Its input end is connected to the motor output shaft, and it transmits motion to both sides of the upper support plate through pulleys and belts. Then, it transmits the motion downward to the rope hinges at both ends of the reciprocating swing actuator through ropes. The reciprocating swing actuator is fixed to the sliders of the upper and lower transverse slider guide mechanisms of the support mechanism, and its two ends are connected to the ropes on both sides through rope hinges. The motor power mechanism drives the ropes to reciprocate through the pulley rope transmission mechanism. Under the traction of the ropes, the reciprocating swing actuator achieves periodic reciprocating motion along the upper and lower transverse slider guides. Due to the interaction of water resistance and traction force, the reciprocating swing actuator forms a certain angle during the reciprocating motion, thereby achieving a reciprocating directional water-pushing effect.

[0008] Furthermore, the support mechanism includes an upper support plate, a lower support plate, a support beam, a column, a transverse slider guide rail mechanism, and a baffle plate. In the transverse slider guide rail mechanism, upper transverse slider bearing seats a and b are connected to upper transverse slider a and upper transverse slider b respectively via bolts and nuts. Upper transverse slider a and upper transverse slider b are connected to upper transverse slide rail a and upper transverse slide rail b respectively.

Similarly, lower transverse slider bearing seats a and lower transverse slider bearing seats b are connected to lower transverse slider a and lower transverse slider b respectively via bolts and nuts. Lower transverse slider a and lower transverse slider b are connected to lower transverse slide rail a and lower transverse slide rail b respectively. Lower transverse slide rail a and lower transverse slide rail b are fixed to the upper surface of the lower support plate via bolts and nuts. The lower transverse slide rail a is equipped with limit switches a and b at both ends. When the reciprocating swing actuator touches limit switch a or limit switch b during its reciprocating motion, it will send an arrival signal to the motor to cause the motor's rotational motion to reverse. The columns include column a, column b, column c, and column d. The four corners of the upper support plate and lower support plate are respectively fixedly connected to column a, column b, column c, and column d. The support beam includes support beam a and support beam b. The two ends of support beam a are respectively fixedly connected to the middle positions of column c and column d, and the two ends of support beam b are respectively fixedly connected to the middle positions of column a and column b. The baffle plate includes baffle plate a and baffle plate b. Baffle plate a is fixedly connected to column c and column d, and baffle plate b is fixedly connected to column a and column b.

[0009] Furthermore, the pulley rope transmission mechanism includes a belt, pulleys, a rope, a rotating shaft, and bearing seats. The input end of the pulley rotating shaft e is connected to the output shaft of the motor via a coupling, and the output end is fixedly connected to pulleys b and c via a key. Both ends are connected to bearing seats c and f respectively, and the middle is connected to bearing seats d and e respectively. Bearing seats c, d, e, and f are fixed to the middle position of the upper surface of the support plate on the support mechanism by bolts and nuts. Pulleys b and c are connected to belt b and belt a respectively, and the other ends of belts a and b are connected to pulleys a and d respectively. The system comprises the following components: Belt pulley a is connected to pulley rotation shaft a, and both ends of pulley rotation shaft a are connected to bearing housing a and bearing housing b, respectively. Bearing housing a and bearing housing b are respectively fixed to one side of the upper surface of the support plate on the support mechanism by bolts and nuts; Belt pulley d is connected to pulley rotation shaft b, and pulley rotation shaft b is respectively connected to bearing housing g and bearing housing h, respectively. Bearing housing g and bearing housing h are respectively fixed to the other side of the upper surface of the support plate on the support mechanism by bolts and nuts; One end of rope d is wound around belt pulley a, and the other end is wound around belt pulley h. Belt pulley h is fixedly connected to the input end of the long shaft b of pulley rotation by a key. The output end of the pulley rotation shaft b is fixedly connected to the pulley g via a key. The pulley rotation shaft b is connected to bearing housings m, n, o, and p. The bearing housings m, n, o, and p are fixedly connected to the support beam b of the support mechanism via bolts and nuts. One end of the rope c is wound around the pulley g, and the other end is fixedly connected to the wing plate b of the reciprocating swing actuator via a rope hinge a. One end of the rope a is wound around the pulley d, and the other end is wound around the pulley e. The pulley e is fixedly connected to the input end of the pulley rotation shaft a via a key. The output end of the pulley rotation shaft a is fixedly connected to the input end of the pulley rotation shaft a via a key. The pulley is fixedly connected to the pulley f. The long shaft a of the pulley is connected to bearing housings i, j, k, and l. The bearing housings i, j, k, and l are fixedly connected to the support beam a of the support mechanism by bolts and nuts. One end of the rope b is wound around the pulley f, and the other end is fixedly connected to the wing plate a of the reciprocating swing actuator C through the rope hinge b. When the reciprocating swing actuator touches the limit switch a or the limit switch b during the reciprocating motion, the motor will change the direction of rotation, thereby realizing the stretching and traction of one end of the rope at both ends of the flapping wing and the release of the other end, effectively realizing the reciprocating swing of the flapping wing to push water.

[0010] Furthermore, the reciprocating oscillating actuator includes a slider guide mechanism, a flapping wing long shaft, a short shaft, a bushing, a bearing seat, a wing plate, a support frame, and a rope hinge. The upper end of the flapping wing long shaft is connected to the upper transverse slider bearing seat a via a bearing, the lower end is connected to the lower transverse slider bearing seat a, and the middle is connected to flapping wing bearing seats a and b. The upper transverse slider bearing seat a and the flapping wing bearing seat b, as well as the lower transverse slider bearing seat a and the flapping wing bearing seat a, are respectively connected by the flapping wing long shaft sleeve b and the flapping wing bearing seat b. The wing long shaft sleeve a is used for axial positioning. The flapping wing bearing seats a and b are fixed to the wing plates a and b respectively by bolts and nuts. The wing plates a and b are fixed together by the lower support frame and the upper support frame of the flapping wing. The other end faces of the wing plates a and b are connected to the rope hinge b and rope hinge a respectively. The rope hinge b and rope hinge a are connected to the rope b and rope c respectively. One end of the upper short shaft of the flapping wing is connected to the upper transverse slider bearing seat b, and the other end is connected to... The flapping wing is connected to the vertical slider bearing seat, which is connected to the flapping wing vertical slider via bolts and nuts. The flapping wing vertical slider is connected to the flapping wing vertical slide rail, which is fixed to the flapping wing upper support frame via bolts and nuts. One end of the flapping wing's lower short shaft is connected to the lower horizontal slider bearing seat b, and the other end is connected to the flapping wing's lower vertical slider bearing seat. The flapping wing's lower vertical slider bearing seat is connected to the flapping wing's lower vertical slider via bolts and nuts. The flapping wing's lower vertical slider is connected to the flapping wing's lower vertical slide rail, which is fixed to the flapping wing's lower support frame via bolts and nuts. The reciprocating swing actuator can achieve horizontal linear motion along the upper and lower horizontal slider track mechanism, vertical linear motion along the flapping wing's upper and lower vertical slider track mechanism, and rotational motion around the upper and lower short and long axes of the flapping wing. Thus, under the interaction of rope traction force and water flow resistance, it forms a certain angle with the water flow, realizing reciprocating, directional, and efficient water pushing operation.

[0011] In this invention, the lever arm formed by the coupling of water resistance, guide rail support force, and rope tension creates a certain angle between the reciprocating oscillating actuator C and the water flow, thereby achieving directional and efficient water-pushing operations under the action of rope traction. This rope-traction-based water-pushing and reoxygenating device exhibits excellent adaptability to the width of the water-pushing channel, meeting the water-pushing and reoxygenating requirements of ultra-wide channels. Compared to existing water-pushing and reoxygenating devices, this invention offers superior operational reliability and efficiency, better overload protection for the belt drive, and a better force-bearing position for the rope-entry traction flapping fin, resulting in higher operational efficiency.

[0012] The beneficial effects of this invention are: improving the environmental adaptability, reliability, and energy efficiency of the water-pushing reoxygenation device, and increasing the hydrodynamics and dissolved oxygen content of the water body. Attached Figure Description

The motor power mechanism A is fixed to a motor support base 2, which is fixed to the middle position of the upper surface of the upper support plate 22 of the support mechanism D by bolts and nuts. The pulley and rope transmission mechanism B fixes the upper support plate and the support beam of the support mechanism D. Its input end is connected to the motor output shaft, and it transmits motion to both sides of the upper support plate through pulleys and belts. The motion is then transmitted downwards to both ends of the reciprocating oscillating actuator C via ropes. The reciprocating swing actuator C is fixed on the sliders of the upper and lower transverse slider guide mechanisms of the support mechanism D, and its two ends are connected to the ropes on both sides through the rope hinges. The motor power mechanism A drives the rope to reciprocate through the pulley rope transmission mechanism B. Under the traction of the rope, the reciprocating swing actuator C realizes periodic reciprocating motion along the upper and lower transverse slider guides. Due to the interaction between water resistance and traction force, the reciprocating swing actuator C will form a certain angle during the reciprocating motion, thereby realizing the reciprocating directional water pushing effect.

[0020] The support mechanism D includes an upper support plate, a lower support plate, a support beam, a column, a transverse slider guide rail mechanism, and a baffle plate.

When the reciprocating swing actuator C touches the limit switch a36 or the limit switch b44 during its reciprocating motion, it will send an arrival signal to the motor 16, so that the rotational motion of the motor 16 will be reversed; the four corners of the upper support plate 22 and the lower support plate 43 are respectively fixedly connected to the columns a1, b6, c35 and d23; the two ends of the support beam a33 are respectively fixedly connected to the middle positions of the columns c35 and d23, and the two ends of the support beam b53 are respectively fixedly connected to the middle positions of the columns a1 and b6; the baffle plate a32 is fixedly connected to the columns c35 and d23, and the baffle plate b49 is fixedly connected to the columns a1 and b6.

[0021] The pulley rope transmission mechanism B includes a belt, pulleys, a rope, a rotating shaft, and bearing seats. The input end of the pulley rotating shaft e69 is connected to the output shaft of the motor 16 via a coupling 15, and the output end is fixedly connected to pulleys b13 and c14 via a key.

Bearing seats c9, d10, e11, and f12 are fixed to the middle position of the upper surface of the support plate 22 on the support mechanism D by bolts and nuts. Pulleys b13 and c14 are connected to belts b17 and a8 respectively. The other ends of belts a8 and b17 are connected to pulleys a7 and d19, respectively. Pulley a7 is connected to pulley rotation shaft a4, and both ends of pulley rotation shaft a4 are connected to bearing housing a3 and bearing housing b5, respectively. Bearing housing a3 and bearing housing b5 are fixed to one side of the upper surface of support plate 22 on support mechanism D by bolts and nuts.

One end of the rope c46 is wound around the pulley g59, and the other end is fixedly connected to the wing plate b48 of the reciprocating swing actuator C by the rope hinge a45.One end of the rope a24 is wound around the pulley d19, and the other end is wound around the pulley e27. The pulley e27 is fixedly connected to the input end of the pulley rotation long shaft a30 by a key. The output end of the pulley rotation long shaft a30 is fixedly connected to the pulley f31 by a key. The pulley rotation long shaft a30 is connected to bearing housings i25, j26, k28, and l29. 9 is fixed to the support beam a33 of the support mechanism D by bolts and nuts. One end of the rope b34 is wrapped around the pulley f31, and the other end is fixed to the wing plate a39 of the reciprocating swing actuator C through the rope hinge b68. When the reciprocating swing actuator C touches the limit switch a36 or the limit switch b44 during the reciprocating motion, the motor 16 will change the direction of rotation, thereby realizing the stretching and traction of one end of the rope at both ends of the flapping wing and the release of the other end, effectively realizing the reciprocating swing of the flapping wing to push water.

[0022] The reciprocating oscillating actuator C includes a slider guide mechanism, a flapping wing long shaft, a short shaft, a bushing, a bearing seat, a wing plate, a support frame, and a rope hinge. The upper end of the flapping wing long shaft 52 is connected to the upper transverse slider bearing seat a63 via a bearing, the lower end is connected to the lower transverse slider bearing seat a41, and the middle is connected to the flapping wing bearing seats a40 and b47. The upper transverse slider bearing seat a63 and the flapping wing bearing seat b47, and the lower transverse slider bearing seat a41 and the flapping wing bearing seat a40 are axially positioned by the flapping wing long shaft sleeve b62 and the flapping wing long shaft sleeve a50, respectively. The flapping wing bearing seats a40 and b47 are fixed to the wing plate a39 and the wing plate b48, respectively, by bolts and nuts. 39. Wing plate b48 is fixedly connected to the lower support frame 51 and the upper support frame 65 of the flapping wing. The other end faces of wing plate a39 and wing plate b48 are respectively connected to rope hinge b68 and rope hinge a45.

The upper vertical slider 74 of the flapping wing is connected to the upper vertical slide rail 75 of the flapping wing. The upper vertical slide rail 75 of the flapping wing is fixedly connected to the upper support frame 65 of the flapping wing by bolts and nuts. One end of the lower short shaft 79 of the flapping wing is connected to the lower transverse slider bearing seat b80, and the other end is connected to the flapping wing vertical slider bearing seat 78. The flapping wing vertical slider bearing seat 78 is connected to the flapping wing vertical slider 77 by bolts and nuts. The flapping wing vertical slider 77 is connected to the flapping wing vertical slide rail 76, and the flapping wing vertical slide rail 76 is fixed to the lower support frame 51 of the flapping wing by bolts and nuts. The reciprocating swing actuator C can realize transverse linear motion along the upper and lower transverse slider track mechanism, vertical linear motion along the flapping wing vertical slider track mechanism, and rotational motion around the upper and lower short and long axes of the flapping wing. Thus, under the interaction of rope traction force and water flow resistance, it forms a certain angle with the water flow, realizing reciprocating, directional, and efficient water pushing operation.

[0023] The motion process in this embodiment is as follows:

[0024] When the motor 16 rotates in both directions, it drives the pulley shaft e69 to rotate via the coupling 15. The pulley shaft e69 is connected to pulleys b13 and c14 via a key, thereby driving pulleys b13 and c14 to rotate at the same speed. Pulleys b13 and c14 drive pulleys a7 and d19 to rotate at the same speed via belts a8 and b17. Pulleys a7 and d19 are respectively wound with ropes d61 and a24. Ropes d61 and a24 drive pulleys h60 and e27 to rotate at the same speed. Pulleys h60 and e27 drive the pulley rotation axis b58 and a30 to rotate at the same speed via a key. The rotating long shaft b58 and the pulley rotating long shaft a30 are connected by keys to drive the pulleys g59 and f31 to rotate at the same speed. The pulleys g59 and f31 are wound with ropes c46 and b34 in opposite directions, respectively, to achieve simultaneous traction and release of the ropes. The ropes c46 and b34 are pulled onto the wing plates b48 and a39 of the reciprocating oscillating actuator C via rope hinges a45 and b68, respectively. This causes the reciprocating oscillating actuator C to move linearly along the upper and lower transverse slider track mechanism and the upper and lower vertical slider track mechanism of the flapping wing, and to rotate around the upper and lower short and long axes of the flapping wing. Thus, during the reciprocating motion, it maintains a certain angle with the water flow, achieving directional water pushing. When the reciprocating oscillating actuator C touches the limit switch a36 or limit switch b44 during its reciprocating motion, the motor 16 changes its rotation direction, thereby driving the reciprocating oscillating actuator C to move back and forth. The water baffles a32 and b49 form a water flow channel, which makes the water pushing efficiency higher.

[0025] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
