Description

Technical Field

[0001] This invention relates to the field of navigation aid equipment technology, specifically to an adjustable anchor chain navigation aid based on buoyancy and a method for adjusting its swivel radius. Background Technology

[0002] The mooring structure of a light buoy consists of sinkers and anchor chains. The sinkers serve to secure the buoy to the seabed, while the anchor chain length is typically configured to be 2-3 times the water depth. Excess anchor chain allows for adjustment and increases seabed traction, but it can cause the light buoy to drift within its turning radius. If the buoy's turning radius is too large, it will affect its positioning accuracy and may even obstruct navigation, hindering normal ship passage.

[0003] Especially in waters with high requirements for navigation mark turning radius and high-precision positioning, such as narrow channels, harbor basins, and densely populated areas, it is particularly important to reasonably control the turning radius.

[0004] Therefore, the present invention provides an adjustable anchor chain buoy based on buoyancy and a method for adjusting the turning radius to solve the above problems. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide a buoyancy-based adjustable anchor chain buoy and a method for adjusting its turning radius. A fixed pulley is installed at the upper end of a sinker, with one end of a rope connected to a circular anchor, and the other end passing through the center of the retractable buoy, wrapping around the fixed pulley, and connecting to a connecting ring at the bottom of the retractable buoy. The retractable buoy, under the influence of buoyancy, generates upward buoyancy. Guided by the fixed pulley, the retractable buoy moves upward, tightening the excess anchor chain, thereby reducing the buoy's turning radius and achieving high-precision positioning.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] An adjustable anchor chain buoy based on buoyancy includes a buoy body, a rope, and a sinker. The upper end of the rope is connected to the buoy body, and the lower end passes through a fixed pulley set on the sinker and is connected to a retractable float. The swivel radius of the buoy body can be adjusted by pulling the rope with the retractable float.

[0008] The retractable float includes a wear-resistant sleeve and a float assembly fixed to the side wall of the wear-resistant sleeve. The wear-resistant sleeve is sleeved on the rope between the buoy body and the fixed pulley. The lower end of the rope passes over the fixed pulley and is fixedly connected to the wear-resistant sleeve.

[0009] In one embodiment of the present invention, the float assembly includes a mounting bracket fixed on a wear-resistant sleeve, and the mounting bracket is provided with an inflation / deflation assembly and a power supply module.

[0010] The gas filling and discharging assembly includes a compressor, a condenser, a liquid storage tank, and an evaporator, wherein the evaporator includes an air bladder and seawater covering the outside of the air bladder; the condenser is a spiral tube wound around the liquid storage tank and seawater covering the outside of the spiral tube.

[0011] The airbag, compressor, spiral tube and liquid storage tank are connected in sequence through pipelines to form a closed loop. The liquid storage tank is used to store the liquefied refrigerant.

[0012] In one embodiment of the present invention, the airbag is connected to the compressor via a first pipeline, and a solenoid valve is provided on the first pipeline; the compressor is connected to the spiral tube via a second pipeline, the spiral tube is connected to the liquid storage tank via a third pipeline, the liquid storage tank is connected to the airbag via a fourth pipeline, and a solenoid valve and a throttle valve are provided on the fourth pipeline; the upper part of the liquid storage tank is connected to the air inlet of the compressor via a fifth pipeline.

[0013] In one embodiment of the present invention, the power supply module includes a hydroelectric generator and a battery that are linearly connected.

[0014] In one embodiment of the present invention, the mounting frame includes a lower support plate, a middle support plate, and an upper support plate, which are fixedly mounted on the outside of the wear-resistant sleeve from bottom to top; the water flow generator is fixed between the lower support plate and the middle support plate; the compressor, condenser, and liquid storage tank in the charging and discharging assembly are arranged between the middle support plate and the upper support plate; the evaporator is arranged above the upper support plate; a control box and a battery are also arranged between the middle support plate and the upper support plate; a communication module is arranged inside the control box; a sealed box is arranged outside the compressor, the control box, and the battery; the airbag is arranged on the wear-resistant sleeve above the upper support plate, and it is an ellipsoidal body of revolution, with its major axis coinciding with the axis of the wear-resistant sleeve.

[0015] In one embodiment of the present invention, the hydroelectric generator includes an inner stator fixed on a wear-resistant sleeve and an outer rotor disposed outside the inner stator, wherein power generation blades are uniformly arranged circumferentially on the outer side wall of the outer rotor.

[0016] In one embodiment of the present invention, a plurality of blade supports are uniformly arranged circumferentially on the outer sidewall of the outer rotor. Each blade support includes mounting plates symmetrically arranged vertically on the outer sidewall of the outer rotor. The power generation blade is located between two mounting plates. One end of the power generation blade is rotatably connected to the outer end of the mounting plate via a rotating shaft, and the other end is provided with a limiting stop to prevent the power generation blade from completely entering the space between the two mounting plates.

[0017] As one embodiment of the present invention, the airbag material is selected from Hypalon rubber composite cloth, which consists of Hypalon, polyester fabric and Hypalon from the inside out;

[0018] The surface of the spiral tube is provided with an anti-fouling coating; cylindrical perforated flow guiding and protective nets are provided between the edges of the lower support plate and the middle support plate, and between the edges of the middle support plate and the upper support plate.

[0019] In one embodiment of the present invention, the bottom of the buoy body is connected to a counterweight via a tail tube, and multiple anchor chains are evenly connected to the bottom of the buoy body in a circumferential direction. The lower ends of the multiple anchor chains are connected to the same ring, and the ring is connected to the upper end of the rope via a swivel.

[0020] A method for adjusting the turning radius is provided, which uses an adjustable anchor chain buoy based on buoyancy to adjust the turning radius of the buoy body.

[0021] The beneficial effects of adopting the above technical solution are as follows:

[0022] The buoyancy-based adjustable anchor chain buoy provided by this invention uses a fixed pulley installed on the upper end of a sinker. One end of the rope is connected to a circular anchor, and the other end passes through the center of the retractable float, wraps around the fixed pulley, and connects to a connecting ring at the bottom of the retractable float. The retractable float, subjected to buoyancy, generates upward buoyancy. Guided by the fixed pulley, the retractable float moves upward along the rope, tightening the excess anchor chain and thus reducing the buoy's turning radius, thereby achieving high-precision positioning.

[0023] The retractable float comprises a wear-resistant sleeve and a float assembly. The size of the air bladder can be adjusted via the inflation / deflation mechanism within the float assembly, causing the retractable float to change shape. This allows the wear-resistant sleeve to slide up and down along the rope, adjusting the tension of the anchor chain and, consequently, the swivel radius of the navigation beacon. The inflation / deflation mechanism controls the air bladder size by regulating the gaseous-liquid state of the refrigerant. At room temperature, the refrigerant is in a gaseous state. Through the cooperation of a compressor, spiral tube, and storage tank, seawater can be used to convert the gaseous to liquid state. The storage tank, air bladder, solenoid valve, and throttle valve further enable the liquid-to-gas conversion of the refrigerant using seawater, cleverly achieving adjustment of the buoyancy of the retractable float on the seabed.

[0024] By incorporating a hydroelectric generator and a battery, autonomous power generation and storage can be achieved, realizing self-sufficiency in electricity. The generator blades in the hydroelectric generator have an ingenious design that allows them to operate in various seawater flow directions. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the invention will be described clearly and completely below in conjunction with specific embodiments.

[0035] like Figure 1 The present invention relates to an adjustable anchor chain buoy based on buoyancy, which includes a buoy body 1, a rope 6 and a sinker 7. The upper end of the rope 6 is connected to the buoy body 1, and the lower end passes through a fixed pulley 8 set on the sinker 7 and is connected to a retractable float. The radius of rotation of the buoy body 1 can be adjusted by the pull of the retractable float on the rope 6. The rope 6 is made of wear-resistant stainless steel.

[0036] The retractable float includes a wear-resistant sleeve 10 and a float assembly fixed on the side wall of the wear-resistant sleeve 10. The wear-resistant sleeve 10 is sleeved on the rope 6 between the buoy body 1 and the fixed pulley 8. The lower end of the rope 6 passes over the fixed pulley 8 and is fixedly connected to the wear-resistant sleeve 10.

[0037] The anchor chain buoy is constructed by adding a fixed pulley 8 to the upper end of the sinker 7. One end of the rope 6 is connected to the circular ring 5, and the other end passes through the center of the retractable buoy, wraps around the fixed pulley 8, and connects to the connecting ring 31 at the bottom of the retractable buoy. The retractable buoy generates upward buoyancy in the seawater, and its maximum buoyancy is less than the weight of the sinker 7. When the buoyancy experienced by the retractable buoy exceeds its own weight, under the guidance of the fixed pulley 8, the retractable buoy will move upward along the rope 6, tightening the excess anchor chain 4, thereby reducing the buoy's turning radius and achieving high-precision positioning.

[0038] In this embodiment, the float assembly includes a mounting bracket fixed on the wear-resistant sleeve 10, and the mounting bracket is provided with an inflation / deflation assembly and a power supply module;

[0039] The gas filling and discharging assembly includes a compressor 15, a condenser, a liquid storage tank 17, and an evaporator, wherein the evaporator includes an air bladder 14 and seawater covering the outside of the air bladder 14; the condenser is a spiral tube 16 wound around the liquid storage tank 17 and seawater covering the outside of the spiral tube 16.

[0040] The airbag 14, compressor 15, spiral tube 16 and liquid storage tank 17 are connected in sequence through pipelines to form a closed loop. The liquid storage tank 17 is used to store the liquefied refrigerant.

[0041] like Figure 2 and Figure 8 As shown, specifically, the airbag 14 is connected to the compressor 15 through a first pipeline, and a solenoid valve 18 is provided on the first pipeline; the compressor 15 is connected to the spiral tube 16 through a second pipeline, the spiral tube 16 is connected to the liquid storage tank 17 through a third pipeline, the liquid storage tank 17 is connected to the airbag 14 through a fourth pipeline, and a solenoid valve 18 and a one-way throttle valve 19 are provided on the fourth pipeline; the upper part of the liquid storage tank 17 is connected to the air inlet of the compressor 15 through a fifth pipeline.

[0042] In this embodiment, the mounting frame includes a lower support plate 11, a middle support plate 12, and an upper support plate 13, which are fixed to the outside of the wear-resistant sleeve 10 from bottom to top. The hydroelectric generator 23 is fixed between the lower support plate 11 and the middle support plate 12. The compressor 15, condenser, and liquid storage tank 17 in the gas charging and discharging assembly are arranged between the middle support plate 12 and the upper support plate 13, and the evaporator is arranged above the upper support plate 13. A control box 20 and a battery 21 are also arranged between the middle support plate 12 and the upper support plate 13. The control box 20 is equipped with an underwater communication module for data transmission and remote control with the control room on the ground. A sealed box 22 is provided outside the compressor 15, the control box 20, and the battery 21. The sealed box 22 is a non-metallic pressure-resistant sealed chamber or an oil-filled pressure balance chamber, which is insulated, heat-dissipating, does not shield communication signals, and can balance external water pressure. In addition, a level gauge is installed inside the liquid storage tank 17 to monitor the amount of liquid refrigerant, thereby allowing the volume of the gaseous refrigerant to be estimated, and the volume and buoyancy of the airbag 14 to be obtained. The airbag 14 is mounted on the wear-resistant sleeve 10 above the upper support plate 13. It is an ellipsoidal body of revolution, with its major axis coinciding with the axis of the wear-resistant sleeve 10. The airbag 14 wraps around the outside of the wear-resistant sleeve 10, and the openings at the upper and lower ends of the airbag 14 are fixedly sealed to the side wall of the wear-resistant sleeve 10.

[0043] The size of the airbag 14 can be adjusted by the inflation / deflation component in the float assembly, causing the retractable float to change, which in turn causes the wear-resistant sleeve 10 to slide up and down along the rope 6, thus adjusting the tightness of the anchor chain 4 and achieving adjustment of the turning radius of the navigation beacon body 1. The inflation / deflation component adjusts the size of the airbag 14 by controlling the gas-liquid state of the refrigerant. At room temperature, the refrigerant is in a gaseous state. Through the cooperation of the compressor 15, the spiral tube 16, and the liquid storage tank 17, seawater can be used to convert the gas-liquid state. Through the liquid storage tank 17, the airbag 14, the solenoid valve 18, and the throttle valve 19, seawater can be used to achieve the liquid-gas conversion of the refrigerant, cleverly realizing the adjustment of the buoyancy of the retractable float on the seabed.

[0044] like Figures 2-4 As shown, the power supply module includes a hydroelectric generator 23 and a battery 21 linearly connected. By setting up the hydroelectric generator 23 and the battery 21, autonomous power generation and power storage can be achieved, realizing self-sufficiency in electricity.

[0045] Specifically, the hydroelectric generator includes an inner stator fixed on a wear-resistant sleeve 10 and an outer rotor 24 disposed outside the inner stator. Multiple generator blades 27 are evenly arranged circumferentially on the outer wall of the outer rotor. The inner stator, fixed on the wear-resistant sleeve 10, is wound with a winding electrically connected to the battery 21. The outer rotor 24 is coaxially sleeved on the outside of the inner stator. Annular limiting rings 33 are symmetrically arranged at the bottom of the middle support plate 12 and the top of the lower support plate 11. Bearings are arranged between the inner sides of the upper and lower ends of the outer rotor 24 and the outer sides of the limiting rings 33. Permanent magnets are evenly arranged on the inner wall of the outer rotor 24. A double-end mechanical seal is provided between the outer rotor 24 and the middle support plate 12 and the lower support plate 11.

[0046] In this embodiment, multiple blade supports are evenly arranged circumferentially on the outer sidewall of the outer rotor 24. Each blade support includes mounting plates 25 symmetrically arranged vertically on the outer sidewall of the outer rotor 24. The power generation blade 27 is located between two mounting plates 25. One end of the power generation blade 27 is rotatably connected to the outer end of the mounting plate 25 via a rotating shaft 28, and the other end is provided with a limiting stop 29 to prevent the power generation blade 27 from completely entering the space between the two mounting plates 25. Figure 3 and Figure 4 As shown, when water flows past the hydroelectric generator, the power generation blades 27 on one side of the outer rotor 24 abut against the water-facing side of the blade support, while the power generation blades 27 on the other side automatically adjust their shape to be in balance with the direction of the water flow. This results in different water flow impact forces on the outer rotor 24, driving the outer rotor 24 to rotate and generate electricity. With this configuration, power generation can be performed through the power generation blades 27 for all seawater flow directions.

[0047] As a further optimization, the mounting plate 25 is triangular with one corner facing outwards, and is inclined towards the side where the limiting stop bar 29 is located, thus optimizing power generation efficiency while ensuring structural strength. As a further optimization, a connecting strip 26 is fixedly connected between the outer ends of the two mounting plates 25 in the blade support to enhance the structural strength and stability of the blade support.

[0048] In this embodiment, the airbag 14 is made of Hypalon rubber composite fabric, consisting of Hypalon, polyester / nylon fabric, and Hypalon from the inside out. The refrigerant is selected based on regional differences and underwater temperature, ensuring that the refrigerant is gaseous at room temperature and easily liquefied by a compressor. R134a, R404A, or R407C can be used as the refrigerant, with R134a being preferred, especially suitable for actual working conditions in water depths less than 50m.

[0049] The spiral tube 16 is made of 316L stainless steel and polished with a silicon-based anti-fouling coating to prevent debris from entangled and microorganisms from adhering. The lower support plate 11, middle support plate 12, and upper support plate 13 are coaxial and disc-shaped with the same diameter. As a further optimization, cylindrical perforated flow-guiding protective nets 30 are provided between the edges of the lower support plate 11 and the middle support plate 12, and between the edges of the middle support plate 12 and the upper support plate 13. The protective nets 30 are made of 316L stainless steel mesh, reinforced nylon grid, or fiberglass, and have uniformly opened holes with a diameter of 15-25mm on the surface, allowing seawater to flow through while blocking seaweed, ropes, etc. As a further optimization, the generator blades 27 are periodically reversed by a controller to remove small entangled objects from the surface of the generator blades 27.

[0050] like Figure 1 As shown, the bottom of the buoy body 1 is connected to a counterweight 3 via a tailpipe 2. Multiple anchor chains 4 are evenly connected around the bottom of the buoy body 1. The lower ends of the multiple anchor chains 4 are connected to the same circular ring 5. Below the circular ring 5, there is an anchor chain 4 connected to a sinker 7. Several swivels 32 are provided on this anchor chain 4. The upper end of the rope 6 is connected to the lower end of this anchor chain 4.

[0051] The fixed pulley 8 is mounted on the sinker 7 via a U-shaped bracket, and the U-shaped bracket is equipped with an anti-detachment mechanism 9 to prevent the rope 6 from detaching from the fixed pulley 8. As a further optimization, the U-shaped bracket is horizontally rotatable and locked onto the sinker 7 to prevent excessive twisting between the ropes 6 on both sides of the fixed pulley 8.

[0052] The fluid generator 23 is linearly connected to the battery 21, and the battery 21 is linearly connected to the solenoid valve 18, the throttle valve 19, the compressor 15, and the electrical components in the control box.

[0053] In addition, the present invention also provides a method for adjusting the turning radius, which achieves the adjustment of the turning radius of the buoy body 1 by means of an adjustable anchor chain buoy.

[0054] When adjusting the turning radius of the navigation mark:

[0055] To reduce the turning radius of the navigation mark, open the solenoid valve 18 on the fourth pipeline. The heat in the seawater is conducted through the tank body of the liquid storage tank 17, causing the refrigerant in the tank to vaporize and enter the air bladder 14, thus expanding the air bladder 14. This increases the buoyancy of the seawater on the retractable float, causing the retractable float to rise and pulling the excess anchor chain 4, thereby reducing the turning radius of the navigation mark.

[0056] To increase the turning radius of the navigation beacon, open solenoid valve 18 on the first pipeline, close solenoid valve 18 on the fourth pipeline, and start compressor 15. The compressor draws gas from the airbag 14, compresses and heats it, and then the gas enters the upper end of the thermally conductive spiral tube 16. Under seawater cooling, the gas condenses into a liquid state and enters the storage tank 17 from the bottom. Simultaneously, the gas generated in the storage tank 17 re-enters the compressor 15 through the fifth pipeline via the compressor's inlet for further compression and heating, thus compressing and condensing the gas inside the airbag 14. Once the turning radius of the navigation beacon has increased to a suitable size, shut down compressor 15 and close all solenoid valves 18 to maintain a stable volume of the airbag 14.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
