The types of buoys launched underwater are mainly divided into two types: one is only to carry a tail propeller, and only to carry out simple launching and floating, but not to carry out steering; the other type of the steering device is additionally provided with external steering devices such as a tail rudder or a side rudder and the like, and can carry out launching, steering and floating, but the external steering devices are easy to damage when in navigation and influence the steering function.
Disclosure of Invention
To solve the above problems, it is an object of the present invention to provide a float steering apparatus based on a change in the center of gravity, which can effectively steer a float and is built-in steering with high reliability.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a buoy steering device based on center of gravity change, comprising:
the base is fixedly arranged in the circular accommodating cavity in the buoy;
one end of the central shaft is fixedly connected with the base and is arranged in the circular accommodating cavity, and the central shaft is coaxial with the circular accommodating cavity;
the balancing weights are sequentially and rotatably connected to the circumferential outer wall of the central shaft along the axial direction of the central shaft, and a circle of track is arranged on the inner wall of the circular accommodating cavity corresponding to each balancing weight;
each track is provided with one track motor which can move along the track, and the other end of each track motor is connected with the corresponding balancing weight;
the track motor moves along the track to drive the balancing weight to rotate around the central shaft so as to adjust the gravity center of the buoy and realize steering.
According to an embodiment of the present invention, the weight member is fan-shaped, and is sleeved on and rotatably connected to the central shaft.
According to an embodiment of the invention, the center of gravity of the base, the central shaft and the center of gravity of the float are located on the same vertical line.
According to an embodiment of the invention, the base is located at an upper portion of the buoy.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following advantages and positive effects:
(1) in the embodiment of the invention, the track motor drives the balancing weight to rotate around the central shaft so as to change the gravity center of the buoy, thereby realizing the steering of the buoy when the buoy is launched and lifted underwater.
(2) In the embodiment of the invention, the base is positioned at the upper part of the buoy, so that the whole device can be positioned at the upper part of the buoy, the gravity center of the buoy can be changed more easily, and the weight of the balancing weight can be reduced under the same effect.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and distinctly aiding in the description of the embodiments of the invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
Referring to fig. 1 to 3, the core of the present invention is to provide a buoy steering device based on gravity center change, which comprises a base, a central shaft 1, a plurality of counterweights 2 and a track motor 3.
The base is fixedly arranged in the circular accommodating cavity inside the buoy and is positioned at the upper part of the buoy. The upper end of center pin 1 links firmly in the base, and center pin 1 is located circular holding chamber simultaneously, and center pin 1 sets up with circular holding chamber is coaxial. The gravity centers of the base and the central shaft 1 and the gravity center of the buoy are positioned on the same vertical line.
The balancing weights 2 are sequentially and rotatably connected to the circumferential outer wall of the central shaft 1 along the axial direction of the central shaft, that is, the balancing weights 2 can rotate on the circumferential outer wall of the central shaft 1 around the axis circumference. In this embodiment, the weight member 2 is fan-shaped and is sleeved on and rotatably connected to the central shaft 1.
A circle of track is arranged on the inner wall of the circular containing cavity at the corresponding position of each balancing weight 2, a track motor 3 capable of moving along the track is arranged on each track, and the other end of each track motor 3 is connected with the corresponding balancing weight 2.
The track motor 3 moves along the track to drive the balancing weight 2 to rotate around the central shaft 1 so as to adjust the gravity center of the buoy and realize steering.
The working process of the present invention is further explained as follows:
firstly, the buoy is launched underwater, when a steering signal is not received, each track motor 3 drives the balancing weight 2 to be uniformly distributed on the central shaft 1, so that the gravity center of the buoy is kept vertical, the gravity and the tail propelling force are positioned on the same straight line, and the buoy can stably keep straight-line rising under the condition of no influence of other external forces.
After the buoy receives the steering signal, the counterweight block 2 rotates to a specified angle under the control of each track motor 3, so that the gravity center of the buoy is changed, the gravity of the buoy and the thrust of the tail part are not on the same straight line, the thrust of the tail part and the gravity are combined into an upward thrust, a moment is formed to enable the buoy to incline to the specified angle and deflect, the original ascending direction is changed, the steering function is realized, and finally the floating place is changed.
The invention adopts the steering device built in the buoy, and effectively solves the problem that the external steering device is easy to damage. The problem that the steering cannot be carried out without an external steering device is solved, and the problem that the external steering device is easy to damage when used is also effectively solved. The built-in steering device is designed, the two states of steering and straight-line rising can be smoothly switched by utilizing the balancing weight 2 according to transmission signals, and the function of the built-in steering device is similar to that of the built-in steering device but is safer.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, it is still within the scope of the present invention if they fall within the scope of the claims of the present invention and their equivalents.
