Description

Technical Field

[0001] The present invention relates to the technical field of fixed-point buoys, in particular to a self-resetting deep-sea fixed-point buoy. Background Art

[0002] At present, all buoys for fixed-point observation at sea are anchored and fixed at a station in a certain sea area to realize the function of observing marine elements. This requires the configuration of an anchoring mooring system that is much deeper than the water depth. In the deep sea, the cost of using the anchoring mooring system is high, and self-resetting deep-sea fixed-point buoys will be used. In the prior art: the patent with authorization publication number CN207943143U discloses an anchor-free, automatically reset deep-sea fixed-point observation buoy, which includes a buoy body and a dynamic positioning system. A small observation platform is provided on the top of the buoy body, and a meteorological observation sensor can be installed on the observation platform. It is connected to the buoy through a mast to form an integral whole. The dynamic positioning system consists of a wind speed and direction meter, a barometer, a positioning instrument, a flat solar panel installed on the observation platform, a flexible solar panel on the mast, a current meter installed under the buoy, a propulsion motor, a propeller, a controller and software. Once the buoy drifts under the action of wind and current, it will automatically return to the set station position with the help of its own power system to continue observation, which greatly reduces the fixed cost. However, there is a lack of components for controlling the direction of the propulsion motor and propeller, and the direction control is not flexible and convenient enough. For this reason, we propose a self-resetting deep-sea fixed-point buoy. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a self-resetting deep-sea fixed buoy, which can use the thrust generated by the rotation of the propeller to position the buoy, reducing the anchoring cost, and the direction of the propeller is simple to control.

During the automatic positioning process, the impact force of the water flow can be used to ensure that the direction of the propeller center axis is parallel to the direction of the water flow, and then the motor can be used to drive the rotational force of the propeller to resist the impact force of the water flow, thereby ensuring the positioning of the float, thereby reducing the fixing cost and having a good positioning effect, and the propeller direction can be actively adjusted, and then it can be actively moved in any direction for reset, ensuring convenience during reset, and providing protection for the positioning of the float, and at the same time, an adjustable guide plate and positioning plate are provided to adjust and control the resistance to the rotation of the float and the support plate, thereby ensuring the efficiency and accuracy of adjusting the propeller direction.

[0008] Furthermore, the propulsion unit includes a support plate, a drive motor and a propeller. The support plate is arranged in the middle of the outer arc surface of the support tube. The right end of the support plate is provided with a drive motor. The output shaft of the drive motor is provided with a propeller. The input end of the drive motor is electrically connected to the output end of the controller to facilitate the positioning of the float.

[0009] Furthermore, the propulsion unit also includes a guide assembly, which is arranged at the left end of the support plate to facilitate the method of automatically adjusting the propeller.

[0010] Furthermore, the guide assembly includes a support shell 1, a rotating shaft 1 and a guide plate. The support shell 1 is arranged at the left end of the support plate. The interior of the support shell 1 is rotatably connected to the rotating shaft 1 through a sealed bearing. The left end of the rotating shaft 1 is provided with a guide plate to facilitate the use of the force of the water flow to adjust the direction of the propeller.

[0011] Furthermore, the guide assembly also includes an electric push rod and a guide tube. The electric push rod is arranged at the right end of the support shell. The telescopic end of the electric push rod is provided with a guide tube. The spiral sliding hole at the left end of the guide tube is slidingly connected to the sliding column at the right end of the rotating shaft.

A positioning plate is provided at the right end of the rotating shaft 2, and an electric push rod 2 is provided at the left end of the support shell 2. A guide tube 2 is provided at the telescopic end of the electric push rod 2. The guide tube 2 is slidably connected to the sliding column 2 at the left end of the rotating shaft 2. The input end of the electric push rod 2 is electrically connected to the output end of the controller, so as to conveniently limit the rotation of the float.

[0014] Furthermore, an angle sensor is provided on the upper side wall of the float, a detection axis of the angle sensor is fixedly connected to the upper end of the support tube, and an output end of the angle sensor is electrically connected to an input end of the controller, so as to facilitate determination of the propeller direction.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the self-resetting deep-sea fixed-point buoy has the following advantages:

[0016] 1. When the float moves due to the action of the water flow, the guide plate is in a horizontal state with the direction of the water flow due to the impact of the water flow. Then the controller controls the drive motor to operate, and the output shaft of the drive motor drives the propeller. The rotation of the propeller pushes the water body to generate a reverse force, thereby counteracting the force of the water flow to ensure the positioning of the float. In the process of automatic positioning, the impact force of the water flow can be used to ensure that the direction of the propeller center axis is parallel to the direction of the water flow, and then the rotation force of the propeller driven by the motor can be used to resist the impact force of the water flow, thereby ensuring the positioning of the float, thereby reducing the fixing cost and having a good positioning effect.

[0017] 2. The controller controls the operation of the stepper motor. The output shaft of the stepper motor drives bevel gear 1, and bevel gear 1 drives the support tube to rotate through bevel gear 2. The support tube drives the drive motor to rotate around the axis of the support tube through the support plate. At the same time, the positioning plate is installed under the float, so that the resistance of the water flow and the positioning plate can limit the rotation of the float. When the support tube rotates, it will drive the detection shaft of the angle sensor to rotate. The angle sensor can convert the angle information of the support tube rotation into an electrical signal and transmit it to the controller, so that the controller can determine the direction of the support plate. After the direction of the support plate is parallel to the direction to be moved, the telescopic ends of the electric push rod 1 and the electric push rod 2 will retract, and the positioning plate will be flattened and the guide plate will stand up. Then the drive motor will start to operate, and the output shaft of the drive motor will drive the propeller to rotate. The propeller will push the water flow to generate a reverse force to drive itself to move, and then the propeller will drive the support plate to move through the drive motor. The support plate will drive the float to move and reset through the support tube. The propeller direction can be actively adjusted, and then it can be actively moved in any direction for reset, ensuring the convenience of reset and providing guarantee for the positioning of the float.

[0018] 3. The controller controls the operation of electric push rod 1 and electric push rod 2. The telescopic end of electric push rod 1 extends to drive guide tube 1 to move to the left, and then the spiral slide hole of guide tube 1 will drive shaft 1 to rotate ninety degrees through the slide column at the right end of shaft 1. Then shaft 1 drives the guide plate to rotate ninety degrees and will be in a horizontal state. Similarly, the telescopic end of electric push rod 2 drives guide tube 2 to move to the right, and guide tube 2 drives the spiral slide hole at the right end to move to the right. The spiral slide hole at the right end slides relative to the slide column 2 at the left end of shaft 2 and drives shaft 2 to rotate ninety degrees. Shaft 2 drives the positioning plate to rotate ninety degrees and then is in a vertical state. An adjustable guide plate and positioning plate are provided to adjust and control the resistance to the rotation of the float and support plate, thereby ensuring the efficiency and accuracy of adjusting the direction of the propeller.

[0030] Example 2:

[0031] The difference between this embodiment and the first embodiment is that: in this embodiment, the propulsion unit 8 includes a support plate 81, a drive motor 82 and a propeller 83.

The relay ring is provided at the upper end of the outer arc surface of the support tube 7;

[0032] Specifically, it is set up like this. When the float 1 moves under the action of the water flow, the guide plate 843 is in a horizontal state with the direction of the water flow due to the force of the water flow impact. Then the controller 5 controls the drive motor 82 to operate. The output shaft of the drive motor 82 drives the propeller 83. The propeller 83 rotates to push the water body to generate a reverse force, thereby counteracting the force of the water flow to ensure the positioning of the float 1. Even when the offset position of the float 1 is far, the controller 5 controls the electric push rod 1 844 and the electric push rod 2 17 to operate. The telescopic end of the electric push rod 1 844 extends to drive the guide tube 1-845 moves to the left, and then the spiral sliding hole of the guide tube 1-845 will drive the rotating shaft 1-842 to rotate ninety degrees through the sliding column at the right end of the rotating shaft 1-842, and then the rotating shaft 1-842 drives the guide plate 843 to rotate ninety degrees to be in a horizontal state, and the driving motor 82 runs, and the output shaft of the driving motor 82 drives the propeller 83 to rotate, and the propeller 83 will push the water flow to generate a reverse force to drive itself to move, and then the propeller 83 will drive the support plate 81 to move through the driving motor 82, and the support plate 81 will drive the float 1 to move and reset through the support tube 7;

[0033] Example 3:

[0034] The difference between this embodiment and the first embodiment is that:

[0035] In this embodiment, a stepper motor 11 is provided inside the float 1, and a bevel gear 12 is provided on the output shaft of the stepper motor 11. A bevel gear 2 13 is provided at the upper end of the support tube 7. The bevel gear 12 is meshed with the bevel gear 2 13. The input end of the stepper motor 11 is electrically connected to the output end of the controller 5. A support shell 2 14 is provided on the lower surface of the float 1. The support shell 2 14 provides an installation position for other components. The interior of the support shell 2 14 is rotatably connected to a rotating shaft 2 15 through a sealed bearing. A positioning plate 16 is provided at the right end of the rotating shaft 2 15. An electric push rod 2 17 is provided at the left end of the support shell 2 14. A guide tube 2 18 is provided at the telescopic end of the electric push rod 2 17. The guide tube 2 18 is slidably connected to the sliding column 2 at the left end of the rotating shaft 2 15. The input end of the electric push rod 2 17 is electrically connected to the output end of the controller 5. An angle sensor 19 is provided on the upper side wall of the float 1. The detection shaft of the angle sensor 19 is fixedly connected to the upper end of the support tube 7, and the output end of the angle sensor 19 is electrically connected to the input end of the controller 5.

[0036] Specifically, it is set up like this. Similarly, the telescopic end of the electric push rod 2 17 drives the guide tube 2 18 to move to the right, and the guide tube 2 18 drives the spiral slide hole at the right end to move to the right. The spiral slide hole at the right end slides relative to the slide column 2 at the left end of the rotating shaft 2 15 and drives the rotating shaft 2 15 to rotate 90 degrees. The rotating shaft 2 15 drives the positioning plate 16 to rotate 90 degrees and then is in a vertical state. Then the controller 5 controls the stepper motor 11 to operate, and the output shaft of the stepper motor 11 drives the bevel gear 1 12. The bevel gear 12 drives the support tube 7 to rotate through the bevel gear 2 13. The support tube 7 drives the drive motor through the support plate 81. 82 rotates around the axis of the support tube 7, and the positioning plate 16 is installed under the float 1, so that the resistance of the water flow and the positioning plate 16 can limit the rotation of the float 1. When the support tube 7 rotates, it will drive the detection axis of the angle sensor 19 to rotate. The angle sensor 19 can convert the angle information of the rotation of the support tube 7 into an electrical signal and transmit it to the controller 5, so that the controller 5 can determine the direction of the support plate 81. After the direction of the support plate 81 is parallel to the opposite direction to be moved, the telescopic ends of the electric push rod 1 844 and the electric push rod 2 17 are retracted, and then the positioning plate 16 will be flattened and the guide plate 843 will stand up.

[0037] The working principle of a self-resetting deep-sea fixed-point buoy provided by the present invention is as follows: when in use, the float 1 is placed in the deep sea, and the external marine meteorological sensor can be installed on the outer arc surface of the support column 3 as needed. The interior of the float 1 is a hollow structure, and a rotating sealing ring is provided at the connection between the float 1 and the support tube 7 for sealing. The float 1 can float to the sea surface, and the counterweight shell 9 and the internal battery 10 have a large density and will sink into the interior of the sea water and prevent the float 1 from overturning. When in use, the controller 5 is adjusted, and the navigation light 4 is powered on to emit bright light to facilitate the observation of the float 1 and prevent collisions with ships. During use, the positioning and orientation GNSS receiver 6 receives satellite signals, and then transmits its own position information and movement information to the controller 5. When the float When the ball 1 is moved by the action of the water flow, the stepper motor 11 is in an unpowered state and can rotate freely. Under the force of the water flow, the guide plate 843 is in a horizontal state with the direction of the water flow, and then the controller 5 controls the drive motor 82 to operate. The output shaft of the drive motor 82 drives the propeller 83. The propeller 83 rotates to push the water body to generate a reverse force, thereby counteracting the force of the water flow to ensure the positioning of the float 1. Even when the offset position of the float 1 is far, the controller 5 controls the electric push rod 1 844 and the electric push rod 2 17 to operate. The telescopic end of the electric push rod 1 844 extends to drive the guide tube 1 845 to move to the left, and then the spiral slide hole of the guide tube 1 845 will pass through the slide column at the right end of the rotating shaft 1 842. Drive the rotating shaft 11 842 to rotate 90 degrees, and then the rotating shaft 1 842 drives the guide plate 843 to rotate 90 degrees to be in a horizontal state. Similarly, the telescopic end of the electric push rod 2 17 drives the guide tube 2 18 to move to the right, and the guide tube 2 18 drives the spiral slide hole at the right end to move to the right. The spiral slide hole at the right end slides relative to the slide column 2 at the left end of the rotating shaft 2 15 and drives the rotating shaft 2 15 to rotate 90 degrees. The rotating shaft 2 15 drives the positioning plate 16 to rotate 90 degrees and then be in a vertical state. Then the controller 5 controls the stepping motor 11 to operate, and the output shaft of the stepping motor 11 drives the bevel gear 12. The bevel gear 12 drives the support tube 7 to rotate through the bevel gear 2 13. The support tube 7 drives the drive motor 82 to rotate around the axis of the support tube 7 through the support plate 81. The support tube 7 rotates, and the positioning plate 16 is installed under the float 1, so that the resistance of the water flow and the positioning plate 16 can limit the rotation of the float 1. When the support tube 7 rotates, the detection shaft of the angle sensor 19 will be driven to rotate. The angle sensor 19 can convert the angle information of the support tube 7 rotation into an electrical signal and transmit it to the controller 5, so that the controller 5 can determine the direction of the support plate 81. After the direction of the support plate 81 is parallel to the direction to be moved, the telescopic ends of the electric push rod 1 844 and the electric push rod 2 17 are retracted, and the positioning plate 16 will be flattened, and the guide plate 843 will stand up. Then the drive motor 82 will run, and the output shaft of the drive motor 82 will drive the propeller 83 to rotate. The propeller 83 will push the water flow to generate a reverse force to drive itself to move.Then the propeller 83 will drive the support plate 81 to move through the drive motor 82, and the support plate 81 will drive the float 1 to move and reset through the support tube 7.
