Description

Technical Field

[0001] This invention belongs to the field of surface detection buoys, specifically relating to a small buoy and a method for achieving its coordinated action. Background Technology

[0002] Small buoys are attached to and travel alongside underwater vehicles. After detaching from the underwater vehicle, they can reliably surface and float stably, providing external detection information and possessing surface target detection capabilities. Equipped with different detection payloads, these small buoys can accurately detect and track distant surface targets, obtaining their location and distance in real time.

[0003] The prerequisite for buoy detection is that the detection device maintains a certain height above the water surface and the buoy's floating attitude is stable. Raising the detection device causes the buoy's center of gravity to shift upwards, and the buoy's swaying and rising / falling with the waves further affects its floating attitude, thus reducing the accuracy of the detection device. Therefore, buoy detection requires a mechanism to raise the detection device and a mechanism to adjust the buoy's attitude. Due to space constraints, the buoy's dimensions are less than half that of an underwater vehicle, making the raising of the detection device and dynamic attitude adjustment within the buoy's confined space a significant technical challenge. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a small buoy and a method for realizing its coordinated action, which coordinates the lifting of the detection device and the adjustment of the buoy's attitude. The coordinated action has high reliability and solves the technical problem of raising the detection device and dynamically adjusting the buoy's attitude in a confined space.

[0005] The objective of this invention is achieved through the following technical solution: a small buoy, comprising a detection device, a float gas cylinder, a deployment gas cylinder, a fairing, a shell, a gas cylinder mounting clamp, a lifting gas cylinder, an inflation pressure plate, a float, and a telescopic mechanism.

[0006] The gas cylinder mounting clip is located inside the housing.

[0007] The float gas cylinder, the deployment gas cylinder, and the lifting gas cylinder are fixed to the shell by the gas cylinder mounting clamp.

[0008] The fairing is fixed in a groove on the housing and connected to the housing by a breakable screw.

[0009] The inflation plate is located below the gas cylinder mounting clip and is fixed inside the housing.

[0010] The float has a built-in inflation seat, and the float is fixed to the shell through the inflation connector.

[0011] The detection device is fixed to the upper end of the piston chamber, and the telescopic mechanism is fixed to the housing by four screws.

[0012] The float cylinder, lifting cylinder, and deployment cylinder are connected by wires to the control system of the buoy's tail section. The tail section control system controls the inflation of the corresponding chambers by these cylinders.

[0013] Preferably, the float has 8 built-in inflatable seats, and the float is fixed to the shell through 8 inflatable connectors.

[0014] Preferably, the inflatable pressure plate is fixed to the housing by a set of screws.

[0015] Preferably, the maximum diameter of the inflatable bladder after inflation is 4 times that of the buoy.

[0016] In addition to providing a small buoy, this invention further provides a method for achieving coordinated action of the aforementioned small buoy, used to coordinate the lifting of the detection device and the adjustment of the buoy's attitude, specifically including the following steps:

[0017] After the buoy rises to the surface, the control system at the buoy's tail section sends a working command to the float gas cylinder. Upon receiving the command, the float gas cylinder inflates the float, causing it to expand and break the breakable screw connecting the fairing and the shell. After a few seconds, the deployment gas cylinder receives a command from the tail section control system to inflate the sealed cavity of the telescopic mechanism. This overcomes resistance and allows the telescopic mechanism to deploy smoothly. The inflated float adjusts the distance between the buoy's center of gravity and buoyancy, stabilizing the buoy's floating attitude. When the buoy's floating attitude meets certain conditions, the control system at the buoy's tail section sends an inflation command to the lifting gas cylinder, inflating the piston cavity and raising the detection device to a certain height, thus coordinating the lifting of the detection device and the adjustment of the buoy's attitude.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This invention provides a small buoy and its coordinated action method. By designing a float with a diameter as large as possible in the middle section of the buoy to adapt to changes in the buoy's center position, the buoy's floating stability is improved. A float gas cylinder is designed to inflate the float, expanding it to a designed diameter that adjusts the buoy's center of gravity, maintaining a stable floating attitude. This invention inflates the piston chamber by raising the gas cylinder; the thrust generated during inflation overcomes the gravity, friction, and breaking force of the breakable screws of the detection device, ensuring the detection device can move to a set height. Deploying the gas cylinder inflates the sealed cavity of the telescopic mechanism, overcoming friction and shear pin resistance to deploy the telescopic mechanism. This invention provides a small buoy and its coordinated action method, collaboratively achieving the lifting of the detection device and the adjustment of the buoy's attitude. The coordinated action has high reliability and solves the technical challenge of raising the detection device and dynamically adjusting the buoy's attitude in confined spaces.

[0024] like Figure 1 As shown, the technical solution of the present invention provides a small buoy, including a detection device 1, a float gas cylinder 2, a deployment gas cylinder 3, a fairing 4, a shell 5, a gas cylinder mounting clamp 6, a lifting gas cylinder 7, an inflation pressure plate 8, a float 9, and a telescopic mechanism 10.

[0025] The gas cylinder mounting clip 6 is located inside the housing 5.

[0026] The float cylinder 2, the deployable cylinder 3, and the lifting cylinder 7 are fixed to the housing 5 by the cylinder mounting clip 6.

[0027] The fairing 4 is fixed in the groove of the housing 5 and connected to the housing 5 by a breakable screw.

[0028] The inflation plate 8 is located below the gas cylinder mounting clip 6 and is fixed inside the housing 5.

[0029] The float 9 has a built-in inflation seat, and the float 9 is fixed to the shell 5 through the inflation connector.

[0030] The detection device 1 is fixed to the upper end of the piston chamber, and the telescopic mechanism 10 is fixed to the housing 5 by four screws.

[0031] The float cylinder 2, the lifting cylinder 3, and the deployment cylinder 7 are connected by wires to the control system of the buoy tail section. The tail section control system controls the inflation of the corresponding chambers by the above cylinders.

[0032] In some embodiments of the present invention, the float 9 has 8 built-in inflatable seats, and the float 9 is fixed to the shell 5 through 8 inflatable connectors.

[0033] In some embodiments of the present invention, the inflatable pressure plate 8 is fixed to the housing 5 by a set of screws.

[0034] In some embodiments of the invention, the float 9, after inflation, has a maximum diameter of four times that of the buoy. In these embodiments, when the float 9 is inflated to a diameter four times that of the adjustable buoy, the buoy's floating attitude remains stable.

[0035] In addition to providing a small buoy, the present invention further provides a method for achieving coordinated action of the aforementioned small buoy, used to coordinate the lifting of the detection device and the adjustment of the buoy's attitude, specifically including the following steps:

[0036] After the buoy rises to the surface, the control system at the buoy's tail section sends a working command to the float gas cylinder 2. Upon receiving the command, the float gas cylinder 2 inflates the float 9. The inflated float 9 expands and breaks the breakable screw connecting the fairing 4 and the shell 5. After a few seconds, the deployment gas cylinder 3 receives a command from the tail section control system to inflate the sealed cavity of the telescopic mechanism 10. This overcomes resistance and allows the telescopic mechanism 10 to deploy smoothly. The inflated float 9 adjusts the distance between the buoy's center of gravity and buoyancy, stabilizing the buoy's floating attitude. When the buoy's floating attitude meets the predetermined conditions, the control system at the buoy's tail section sends an inflation command to the lifting gas cylinder 7, inflating the piston cavity and raising the detection device 1 to a certain height, thus coordinating the lifting of the detection device and the adjustment of the buoy's attitude.

[0037] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
