Description

Technical Field

[0001] This application relates to the technical field of new energy utilization, and particularly relates to a buoy for waterways with a cleaning mechanism. Background Art

[0002] A buoy refers to a navigation mark floating on the water surface. It is anchored at a designated position to mark the waterway range, indicate shoals, navigational hazards, or represent a water surface navigational aid for special purposes. Buoys are the most numerous and widely used in navigation marks, and are set in places where it is difficult or inappropriate to set fixed navigation marks. A buoy equipped with a lamp is called a lighted buoy and is used for navigation in waters with day and night traffic.

[0003] In the prior art, some buoys are also equipped with devices such as radar transponders, radio beacons, fog warning signals, and marine survey instruments. However, existing buoys cannot be used when the power supply system suddenly fails. For this reason, some buoys also introduce a tidal current turbine to supply power to the buoy. Tidal current energy refers to the kinetic energy contained in the horizontal flow of seawater or river water, which is a type of renewable energy. Since the principle of tidal current energy generation is similar to that of wind energy generation, a tidal current energy generation device converts the kinetic energy of flowing water into mechanical energy for power generation. However, during the rainy season in the Yangtze River Basin, due to heavy rainfall, the weeds on the mountains are washed away by the rain and gather in the river water, resulting in a large number of weeds in the Yangtze River Basin during the rainy season, causing congestion. A large number of weeds in the basin will adhere to the outer wall of the tidal current turbine under the buoy. When the amount of waterweed reaches a certain level, it will cause the buoy to shift, greatly affecting the normal operation of the waterway facilities.

[0004] Therefore, considering the weeds, it is of great significance to realize the supply of water flow energy for the navigation and flow velocity monitoring of the buoy. Summary of the Utility Model

[0005] The purpose of this application is to provide a buoy for waterways with a cleaning mechanism to solve the problems of low power generation efficiency and deviation of the buoy position caused by waterweeds winding around the water turbine under the buoy in the prior art.

[0006] The embodiments of this application can be realized through the following technical solutions:

[0007] A buoy for waterways with a cleaning mechanism includes a floating platform, a power generation device, a rotor, and a cleaning mechanism. The power generation device is integrated under the floating platform, and the drive shaft of the power generation device is connected to the rotor;

[0008] The cleaning mechanism includes a telescopic shaft, a second connecting part, and a brush assembly. One end of the telescopic shaft is connected to the power generation device through the drive shaft, and the other end of the telescopic shaft is connected to the brush assembly through the second connecting part. The brush assembly is attached to the surface of the hydrofoil of the rotor. When the telescopic shaft moves up and down along its axial direction, the brush assembly moves up and down on the surface of the hydrofoil.

[0009] Further, the drive shaft is a vertical shaft extending along its axial direction. The rotor includes a hydrofoil and a first connecting part. The drive shaft is connected to the middle of the first connecting part. The first connecting part extends radially along the drive shaft. The hydrofoil is vertically arranged and connected to the side surface of the first connecting part.

[0010] Further, the rotor is a three-blade lift rotor. The number of hydrofoils is three. The three hydrofoils are connected to the side surface of the first connecting part at equal angles, and the brush assembly is arranged corresponding to the hydrofoil.

[0011] Further, the first connecting part is a circular cover plate. The first connecting part is connected to the top of the hydrofoil. A plurality of hydrofoils are arranged along the circumference of the first connecting part.

[0012] Further, the telescopic shaft is a hydraulically driven telescopic rod.

[0013] Further, the drive shaft is a hollow shaft inside. The driving end of the telescopic shaft is connected to the inside of the drive shaft and is connected to the output end of the power generation device.

[0014] Further, the brush assembly is sleeved outside the hydrofoil.

[0015] Further, the brush assembly includes a sleeve plate and a brush. The sleeve plate is a hollow frame structure inside. The brush is connected to the inner wall of the sleeve plate along the circumference of the sleeve plate.

[0016] Further, the cavity formed by the brush along the circumference of the sleeve plate is adapted to the shape of the hydrofoil.

[0017] Further, the brush assembly further includes an elastic body. The brush is connected to the sleeve plate through the elastic body. Under the elastic force of the elastic body, the brush is closely attached to the inner wall of the hydrofoil.

[0018] The buoy for waterway with a cleaning mechanism provided by the embodiment of the present application has at least the following beneficial effects:

[0019] In terms of power supply, the present application adopts the structural form of a vertical-axis water turbine for power supply; in terms of waterweed treatment, the present application installs brushes on each hydrofoil, and three brushes share a telescopic shaft. During the non-flood season, the telescopic shaft rotates synchronously with the drive shaft of the hydroturbine power generation device, and the hydrofoils generate electricity under the action of the incoming flow. The generated electricity is stored in the storage battery of the power generation device. During the flood season, when there is a lot of waterweed attached to the hydrofoils, the waterweed on the hydrofoils is washed off by controlling the up and down movement of the telescopic shaft. This process is powered by the storage battery. Through the above settings, the water flow energy can be fully utilized, resources can be saved, and the problems of low power generation efficiency and deviation of the buoy position caused by waterweed entanglement can be avoided. It has the advantages of simple structure, strong practicability, and long maintenance-free period. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] As Figures 1 to 3 shown, a buoy for a waterway with a cleaning mechanism includes a floating platform 1, a power generation device 2, a rotor 3, and a cleaning mechanism 4. The power generation device 2 is integrated below the floating platform 1. The drive shaft 21 of the power generation device 2 is connected to the rotor 3. When water flows through the rotor 3, the rotor 3 converts the water energy into mechanical energy that drives the drive shaft 21 to rotate, and the drive shaft 21 drives the power generation device 2 to convert the mechanical energy into electrical energy and output it.

[0031] The cleaning mechanism 4 includes a telescopic shaft 41, a second connecting portion 42, and a brush assembly 43. One end of the telescopic shaft 41 is connected to the power generation device 2 through the drive shaft 21, and the other end of the telescopic shaft 41 is connected to the brush assembly 43 through the second connecting portion 42. The brush assembly 43 is attached to the surface of the hydrofoil 31 of the rotor 3. When the telescopic shaft 41 moves up and down along its axial direction, the brush assembly 43 moves up and down on the surface of the hydrofoil 31 to scrape off the waterweeds attached to the surface of the hydrofoil 31.

[0032] Specifically, the drive shaft 21 of the power generation device 2 is a vertical shaft extending along its axial direction. The rotor 3 includes a hydrofoil 31 and a first connecting portion 32. The first connecting portion 32 extends radially along the drive shaft 21. A through hole is provided in the middle of the first connecting portion 32. The hydrofoil 31 is vertically arranged and connected to the side surface of the first connecting portion 32. The drive shaft 21 is connected to the through hole of the first connecting portion 32, so that the hydrofoil 31 is arranged on the side surface of the drive shaft 21. When water flow passes through the hydrofoil 31, the hydrofoil 31 converts water energy into mechanical energy that drives the drive shaft 21 to rotate.

[0033] In some preferred embodiments, the rotor 3 is a three - blade lift rotor. The number of the hydrofoils 31 is three. The three hydrofoils 31 are connected to the side surface of the first connecting portion 32 at equal angles. The angle between any two of the three hydrofoils 31 is 120°, which is used to more effectively utilize lift power generation and reduce resistance, enabling it to rotate faster and more smoothly.

[0034] Correspondingly, the number of the brush assemblies 43 is also three. The brush assemblies 43 are connected to the side surface of the second connecting portion 42 and correspond to the hydrofoils 31 one by one.

[0035] In some preferred embodiments, the first connecting portion 32 is a circular cover plate. The first connecting portion 32 is connected to the top of the hydrofoil 31. A plurality of the hydrofoils 31 are arranged along the circumference of the first connecting portion 32. This is because the circular cover plate can produce a blocking effect when fluid passes through, increase the speed of the fluid below the circular cover plate, and enhance the work performance of the hydrofoil 31.

[0036] In some preferred embodiments, the telescopic shaft 41 is a hydraulically - driven telescopic rod. The hydraulic system of the telescopic shaft 41 includes a hydraulic motor, a liquid storage tank, and a control valve. The hydraulic motor is connected to the liquid storage tank through the control valve. The control valve can control the rotation direction of the hydraulic motor and the flow rate of the liquid, thereby controlling the telescopic movement of the telescopic rod. Compared with an electric telescopic rod, the hydraulically - driven telescopic rod works more stably underwater.

[0037] The drive shaft 21 is a hollow rotating shaft inside. The driving end of the telescopic shaft 41 is connected to the inside of the drive shaft 21 and is connected to the output end of the power generation device 2. On the one hand, during the non - flood season, when the drive shaft 21 rotates, the drive shaft 21 can drive the rotor 3 and the cleaning mechanism 4 to rotate synchronously. The hydrofoil 31 supplies power to the power generation device 2 under the action of water flow. On the other hand, when it is necessary to drive the brush assembly 4 to move up and down to scrape the waterweeds on the hydrofoil 31, the storage battery of the power generation device 2 can supply power to the driving end of the telescopic shaft 41 to ensure that the telescopic shaft 41 can drive the brush assembly 43 to move axially up and down.

[0038] In some preferred embodiments, in order to improve the cleaning efficiency, the brush assembly 43 is sleeved outside the hydrofoil 31.

[0039] Specifically, the brush assembly 43 includes a sleeve plate 431 and a brush 432. The sleeve plate 431 is a frame structure with a hollow interior. The brush 432 is connected to the inner wall of the sleeve plate 431 along the circumferential direction of the sleeve plate 431. The cavity formed by the brush 432 along the circumferential direction of the sleeve plate 431 is adapted to the shape of the hydrofoil 31, so that the brush 432 fits against the outer wall of the hydrofoil 31.

[0040] In some preferred embodiments, in order to improve the cooperation between the brush 432 and the hydrofoil 31, the brush assembly 43 further includes an elastic body 433. The brush 432 is connected to the sleeve plate 431 through the elastic body 433, so that under the elastic force of the elastic body 433, the brush 432 is closely attached to the inner wall of the hydrofoil 31.

[0041] In some preferred embodiments, the elastic body 433 includes structures with elastic characteristics such as springs, rubber bands, and balloons.

[0042] The specific embodiments of the present application have been introduced in detail above. For those skilled in the art of this technology, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
