Description

Technical Field

[0001] This utility model relates to the field of navigation mark technology, and in particular to a novel automatic navigation mark positioning device. Background Technology

[0002] Navigational marks are important reference points for guiding ships through waterways, especially in reservoir environments. Due to changes in water level, navigational marks that can float on the water are needed as reference points for navigation. Existing navigational marks are often anchored to a predetermined target point using anchor stones. However, in order to adapt to changes in water level, the length of their anchor chains is usually longer than the water depth. This causes the navigational mark to move arbitrarily within a circular area centered on the anchor stone. When the water level is low, its radius of movement can reach tens of meters, making the positioning of the navigational mark less accurate and posing a risk to navigational safety.

[0003] Chinese utility model patent CN221660913U discloses a silicon battery adjustable navigation buoy, comprising: a buoy body, a fixed frame above the buoy body, a silicon battery fixedly connected to the top of the fixed frame, and an adjustment mechanism at the top of the buoy body for real-time adjustment of the angle of the silicon battery according to the position of the sun. When the device is working, the light-tracking sensor first determines the position of the sun based on the intensity of light at different angles, controls the drive component to drive the rotating rod to rotate, thereby driving the silicon battery to adjust its angle, achieving real-time tracking of the sun and maximizing energy absorption.

[0004] However, its shortcomings are: there is an unavoidable error between the actual coordinates of the buoy and the preset coordinates; due to changes in water depth, the anchor chain cannot automatically adjust its length to adapt to the changes, which makes the buoy prone to drifting or capsizing in certain environments. Utility Model Content

[0005] The purpose of this invention is to provide a new type of automatic navigation mark positioning device that can automatically adjust and reduce the error between the navigation mark and the preset coordinate point, thereby ensuring the accuracy of the actual trajectory of the waterway.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel automatic navigation beacon positioning device, comprising a float, a tailpipe at the bottom of the float, a light frame at the top of the float, a navigation beacon light at the top of the light frame, a silicon battery power supply system at the top of the light frame, a battery energy storage device inside the tailpipe, an adjustable propulsion system at the bottom of the float, and a navigation positioning system capable of precise positioning inside the float.

[0007] By adopting the above technical solution, the navigation beacon determines its position and the direction of propulsion of its thruster through the navigation and positioning system. Then, based on the position data, the distance between the actual coordinate position and the predetermined position can be reduced by dynamically adjusting the propulsion system. The power supply system provides power to the propulsion system and the navigation beacon light, and the energy storage mechanism can store a certain amount of energy for use in adverse conditions.

[0008] A further feature of this invention is that the silicon battery power supply system includes a silicon battery panel fixed to the top of the lamp holder, the outer surface of the silicon battery panel is frustum-shaped, and the silicon battery is electrically connected to a battery energy storage device.

[0009] By adopting the above technical solution, the silicon solar panel is actually a solar power generation panel. It is fixed on the top of the light frame and can receive sunlight to the maximum extent. Since the outer surface is truncated cone and the inclined side is almost perpendicular to the angle of sunlight, it can maximize the energy of sunlight. At the same time, the silicon solar panel is surrounded by a circle, so it can receive sunlight at different times of the day. The position of the navigation light is higher than the silicon solar panel, so the silicon solar panel will not block the visibility of the navigation light.

[0010] A further feature of this invention is that the battery energy storage device includes a battery fixed inside the tailpipe, the battery supplies power to the propulsion system and navigation lights, and the batteries are electrically connected to each other.

[0011] By adopting the above technical solution, the battery can store electrical energy and power the propulsion system and navigation lights, while the device still has the ability to continue operating at night or when there is no sunlight due to weather conditions.

[0012] A further feature of this invention is that the battery energy storage device is located at the center of gravity of the new anchorless navigation beacon positioning device, and a waterproof outer shell is provided for the battery energy storage device.

[0013] By adopting the above technical solution, the battery is positioned at the center of gravity to prevent it from being in a state of violent motion when the navigation beacon is swaying in the water, which would cause changes in its internal chemical substances and affect the performance and lifespan of the battery. The waterproof casing can prevent external water from accidentally entering and damaging the battery.

[0014] A further feature of this invention is that the propulsion system includes directional thrusters symmetrically fixed on both sides of the float, with the propulsion directions of the directional thrusters being parallel.

[0015] By adopting the above technical solution, the thrusters are set on both sides of the float, and the direction of the beacon's movement can be changed by changing the magnitude of the thruster output.

[0016] A further feature of this invention is that the navigation and positioning system is the BeiDou positioning system.

[0017] By adopting the above technical solutions, the location of navigation marks can be determined using the BeiDou positioning system.

[0018] A further feature of this invention is that the navigation and positioning system is a compass magnetic field orientation instrument, which is used to determine the angle between the target point and the geomagnetic north pole.

[0019] By adopting the above technical solution, the compass magnetic field orientation instrument can determine the angle between the line connecting the beacon body and the preset position and the geomagnetic north pole based on the north pole orientation time, so as to adjust the output of the two directional thrusters at any time and make the beacon move closer to the preset point.

[0020] A further feature of this invention is that the outer shell material of the float is ultra-high molecular weight polyethylene.

[0021] By adopting the above technical solution, ultra-high molecular weight polyethylene can make the structure of the navigation beacon remain stable when it is hit, and it will not deform due to impact.

[0022] A further feature of this invention is that it includes a differential base station fixed on the shore.

[0023] By adopting the above technical solution, the signals transmitted by the navigation and positioning system are amplified through differential base stations.

[0024] The beneficial effects of this utility model are: by using a high-precision dynamic positioning and navigation system to monitor the deviation between the actual coordinates of the buoy and the preset coordinate point in real time, when the deviation value exceeds the set value, the system drives the buoy to move towards the preset coordinate point by a propulsion device, so that the deviation value meets the requirements set by the waterway system, thereby ensuring the accuracy of the actual coordinates of the buoy and ensuring waterway safety.

Detailed Implementation

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] In one embodiment of this utility model, according to the appendix Figure 1 The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0034] A novel automatic navigation beacon positioning device includes a float 1, a tailpipe 2 at the bottom of the float 1, a light frame 11 at the top of the float 1, a navigation beacon light 12 at the top of the light frame 11, a silicon battery power supply system 3 at the top of the light frame 11, a battery energy storage device 4 inside the tailpipe 2, an adjustable propulsion system 5 at the bottom of the float 1, and a navigation positioning system 6 inside the float 1 capable of precise positioning.

[0035] Furthermore, the silicon battery power supply system 3 includes a silicon battery panel 31 fixed on the top of the lamp holder 11. The outer surface of the silicon battery panel 31 is frustum-shaped, and the silicon battery panel 31 is electrically connected to the battery energy storage device 4.

[0036] The battery energy storage device 4 includes a battery 41 fixed inside the tailpipe 2. The battery 41 supplies power to the propulsion system 5 and the navigation light 12. The battery 41 is electrically connected to the silicon solar panel 31. The battery 41 can be a lead-acid battery or a lithium battery. The transformer and other devices required in the process of the silicon solar panel 31 inputting energy into the battery 41 are conventional technologies for solar power generation and are not the target of protection of this utility model, so they are not shown in the figure.

[0037] It should be noted that the battery energy storage device 4 is located at the center of gravity of the new anchorless navigation beacon positioning device, and the battery energy storage device 4 is equipped with a waterproof outer shell.

[0038] As a first embodiment of the present invention, the propulsion system 5 includes directional thrusters 51 symmetrically fixed on both sides of the float 1, and the directional thrusters 51 have parallel propulsion directions.

[0039] In the first embodiment of this utility model, in order to control the direction of movement of the buoy, two parallel thrusters are arranged on both sides of the buoy. During propulsion, the direction can be changed by changing the output of the two thrusters. The thrusters can use existing conventional small thruster technology solutions. Their specific structure and connection and fixing methods can also refer to the relevant technical solutions of small boat hulls. Since this utility model mainly uses solar panels to generate electricity, its power supply is relatively small. Therefore, small thrusters are required as the power source for the buoy's propulsion. This utility model is suitable for use in reservoirs or lakes where the wind and waves are smaller than those at sea. When the weather forecast indicates that the wind and waves on the water surface are large and will exceed the thrust limit of the thrusters, the port can also be used as the reference coordinate point for the buoy, so that the buoy can turn back to avoid the waves.

[0040] As a second embodiment of this utility model, the navigation and positioning system of this utility model is the Beidou positioning system. The Beidou positioning system can determine the position and direction angle of the beacon. This information is analyzed by the differential base station and converted into a signal input to the buoy to control the propulsion direction of the thruster. It should be noted that under low-speed water flow conditions, the position of the beacon does not change significantly, and the signal accuracy of the Beidou positioning system will be lower than the required accuracy threshold, and it cannot provide accurate positioning for the beacon. Therefore, this embodiment is only suitable for situations where the wind and waves are large and the speed of the beacon is fast in lakes.

[0041] In Embodiment 3, the navigation and positioning system of this utility model is a compass magnetic field orientation instrument. By reading information such as the Earth's magnetic field, the compass magnetic field orientation instrument can accurately output parameters such as the orientation and pitch of navigation marks, thereby achieving precise positioning. Its specific structure can adopt existing mature technologies. Figure 3 The method of thruster orientation adjustment is shown, where A is the buoy's reference coordinate point and B is the buoy's dynamic coordinate point, i.e., the buoy's actual position. The angle between the buoy's movement direction and the geomagnetic north pole direction can be calculated by coordinate translation. Since the compass magnetic field orientation instrument is fixed inside the buoy, it can detect the angle between the direction of the line connecting the actual position of the thruster and the target point and the geomagnetic north pole. Based on the angle data, the output of the two thrusters is dynamically adjusted so that the device moves in a straight line towards the target point after turning. After moving a certain distance, the angle may change again due to the impact of the water flow. It is necessary to detect the actual angle value again by the compass magnetic field orientation instrument and adjust the output of the two thrusters. This cycle is continuously adjusted until the buoy reaches the circular area around the buoy's reference coordinate point with acceptable accuracy. The compass magnetic field positioning system determines the translation of the navigation beacon by cutting magnetic field lines and sensing the geomagnetic north pole. Compared with the Beidou positioning system, it has higher accuracy, but it is necessary to ensure that the magnetic field environment of the area where it is used is not affected by other magnetic fields.

[0042] The buoy and reference coordinate orientation adjustment method of this utility model is as follows: Figure 4 As shown, with the positioning base point as the origin, the north-south direction as the ordinate axis Y, and the east-west direction as the abscissa X, the GPS module detects the coordinates of the buoy in the above coordinate system. Using analytical geometry, the distance and axial angle between the buoy and the base point can be calculated. These are then adjusted based on the directional angle information recorded by the compass magnetic field orienting instrument. The distance calculation formula is as follows: The formula for calculating the included angle is: .

[0043] Since the buoy serves as a navigational marker and a carrier for intelligent control instruments, it needs to be equipped with navigation lights, navigation marks, power supply systems, and various testing instruments. Therefore, the buoy must be able to effectively protect itself and the various instruments and mechanisms installed on it, and must not be damaged in various harsh external environments and extreme conditions. Therefore, it is made of ultra-high molecular weight polyethylene material, which has high strength, good impact resistance, and is not prone to aging. Considering the light weight of the buoy and its flexible operation and avoidance, a buoy with a diameter of 3.05 meters was selected, which meets the national standard requirements.

[0044] In order to enable the navigation and positioning system to receive signals better, differential base stations may be built on the ground to amplify the signal transmission power. Differential signal base stations are an existing technical solution and can be set up with reference to existing technologies. Their structure is not the target of protection of this utility model.

[0045] This utility model is suitable for operation in a reservoir environment, and its working method includes:

[0046] 1. After determining the coordinate base point, the buoy is launched into the water. After receiving the signal, the buoy is propelled to the designated position by the thruster. Both the thruster and the navigation light are powered by the solar power system mentioned above. Due to the energy storage function of the battery, the system can still work normally when it cannot be charged due to weather conditions.

[0047] 2. When the buoy's position deviates from the set range due to the impact of water flow, the system drives the propeller according to the above principle until it returns to the normal position;

[0048] 3. When the wind and waves in the reservoir are too large for an extended period of time, exceeding the propeller's ability to return to the correct position, the buoy can also return to port to avoid the storm.

[0049] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

[0050] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
