When the existing buoy carries out course measurement, the measurement track is inaccurate because the carrier and the buoy are inseparable.

In view of the above technical problem, an embodiment of the present invention provides a buoy device, as shown in fig. 1 to 3, including: a carrier 2 and a buoy 1, the carrier being separable from the buoy 1, the buoy 1 comprising a first chamber 10, a second chamber 11, a third chamber 12 and a photodetector 13; wherein, the head of the photoelectric detector 13 is provided with a buckling part; the first chamber 10 is provided with an opening, and a first elastic component 100 is arranged at the opening; a snap ring matched with the buckling part is arranged on the inner wall of the first chamber 10; the clamping ring is clamped with the buckling part so that the photoelectric detector 13 is buckled with the first cavity 10; the second chamber 11 is respectively communicated with the first chamber 10 and the inner cylinder 111 and is used for accommodating the bottom of the photoelectric detector 13; an air bag 110 is arranged on the outer wall of the second chamber 11, and when the air bag 110 is inflated, the buoyancy of the air bag can enable the buoy 1 to float upwards; a controller is provided in the inner cylinder 111 for controlling the float 1 floating speed.

It should be noted that the carrier of the buoy device in this embodiment is separable from the buoy 1, and in particular, in an application, the buoy device floats upwards by the power provided by the air source of the buoy device after being thrown into water, and when the buoy device rises to a preset height, the controller sends a control signal to separate the carrier from the buoy 1.

In this embodiment, the position of the buoy device in the water is sensed by a pressure sensor. When the buoy device is lowered to 10 meters under water, the carrier is separated from the buoy 1.

In an alternative form, as shown in figure 2, the first chamber 10 is connected to the second chamber 11 using a double sealing ring arrangement.

By adopting the above connection mode, the first chamber 10 is used for protecting the photoelectric detector 13 and preventing the photoelectric detector 13 from being corroded and damaged by seawater in a non-working state.

In an alternative mode, as shown in fig. 2, the second chamber 11 is provided with an inner cylinder 111, the lower end and the inner end cap of the inner cylinder 111 are assembled together to form a sealed cavity, and the upper end and the photodetector 13 are connected with the inner cylinder 111 through a double-seal sliding seal structure.

By adopting the above connection mode, the second chamber 11 has sealing performance and mobility of the photodetector 13 during operation, and the head of the photodetector 13 leaks out of the inner cylinder 111 and is located in the sealed cavity of the first chamber 10 before being separated from the first chamber 10.

In an alternative, as shown in FIG. 2, balloon 110 is secured with a hoop around the outside of inner cylinder 111, and two semi-circular separate shells are provided around the outside of balloon 110.

By adopting the technical scheme, the semi-circular separation shell is adopted, so that the streamline structure of the buoy device in water can be ensured, and the resistance of water is reduced; meanwhile, the airbag 110 is folded when not in use, and the semicircular separable case protects the airbag 110. In addition, the folded state of the bladder 110 when not in use reduces the overall bulk of the buoy device.

In an alternative, as shown in fig. 2, the connection between the second chamber 11 and the inner cylinder 111 is made using trapezoidal guides.

Adopt above-mentioned technical scheme, trapezoidal guide rail can realize relative slip between second cavity 11 and inner cylinder 111, and when inner cylinder 111 among the second cavity 11 rebound, trapezoidal guide rail can play the guide effect, and the barycenter reduces when also making buoy 1 come up, has solved the stable problem of come-up gesture.

In the buoy device provided by the embodiment of the invention, the buoy 1 and the carrier can be separated, so that the buoy device can be thrown in a specific place, and the track measurement or target tracking of the specific place is realized. The buoy 1 is internally provided with a photoelectric detector 13 for realizing target tracking or flight path measurement. Because the air bag 110 is arranged on the outer wall of the second chamber 11, the air bag 110 can drive the buoy 1 to float upwards; because the head of photoelectric detector 13 is provided with the knot portion, when the last time of floating to first cavity 10 in of photoelectric detector 13, with the snap ring lock in first cavity 10, effectively protected photoelectric detector 13, avoid photoelectric detector 13 and first cavity 10 to bump and take place to damage for follow-up measurement is more accurate. Meanwhile, the airbag 110 arranged outside the second chamber 11 is inflated to separate the carrier from the buoy 1, the buoy 1 floats upwards to the horizontal plane under the action of buoyancy, and the photoelectric detector 13 is started to perform operations such as course measurement and target tracking.

In an alternative mode, the locking part is mounted at the bottom of the photodetector 13 and is clamped in the locking groove of the inner cylinder 111 by a locking head.

During specific application, the air source inflates the second chamber 11, so that the second chamber 11 is in a floating state, when the photoelectric detector 13 rises to a calibration height, the photoelectric detector 13 can be mechanically self-locked, and stops rising to start working. The adoption of the locking portion can effectively prevent the photodetector 13 from sinking.

As one possible implementation, as shown in fig. 1 to 3, the first elastic member 100 is an elastic net 1002.

In order to ensure that the photoelectric detector 13 can work smoothly when the buoy 1 floats to the water surface, the elastic net 1002 is additionally arranged in the first chamber 10 through screw fastening.

The reliable separation of the first chamber 10 and the second chamber 11 is solved by the elastic force of the elastic net 1002, and the collision of the photodetector 13 with the first chamber 10 when the photodetector rises is effectively avoided.

When the photoelectric detector 13 rises into the first chamber 10, the elastic net 1002 can be touched, the elastic net 1002 deforms, and when the photoelectric detector 13 rises to the maximum deformation position of the elastic net 1002, the elastic net 1002 can eject the first chamber 10 out of the water surface, and the photoelectric detector 13 works.

As a possible implementation manner, as shown in fig. 3, at least one elastic band 1001 is provided on the elastic net 1002, one end of the at least one elastic band 1001 is connected to the elastic net 10021002, and the other end is fixedly connected to the first chamber 10.

In this embodiment, the elastic net 1002 can be stretched in any direction, so that when the photodetector 13 contacts the elastic net 1002 in any direction, the elasticity of the elastic net 1002 can buffer the photodetector 13 and protect the photodetector 13.

As a possible implementation, as shown in fig. 1 to 2, a power supply and a gas source are further disposed in the inner cylinder 111, the power supply is used for supplying power to the photodetector 13, and the gas source is used for supplying gas to the air bag 110 and the second chamber 11.

In this embodiment, the inner cylinder 111 is provided with a battery compartment housing, wherein the battery compartment housing is divided into two sealed cavities, the upper and lower end faces are fastened by two sealed end covers with screws, and the sealed cavity has a sealing function, and the annular groove on the upper cavity is assembled with a power supply, and when the sealed cavity is used, a battery is adopted for supplying power. Two layers of control panels are supported and fixed in the inner cylinder 111 through two supports; the middle part is also provided with a non-sealed cavity for placing an air source and a controller, an air tap on the air source is communicated with the second cavity 11 through an air passage, one path of air and an inner end cover on the second cavity 11 are directly connected into the inner cylinder 111, and the other path of air is connected into the air bag 110 through the inner end cover and the air passage.

As a possible implementation, as shown in fig. 1 to 2, the outer wall of the airbag 110 is provided with a detachable housing, and the detachable housing is detachably connected with the second chamber 11 through a second elastic member.

In an alternative mode, one end of the separation shell is clamped in the groove of the inner cylinder 111, the other end of the separation shell is clamped in the groove of the bottom shell in the inner cylinder 111, and the separation shell is tightly propped against the groove in a direction perpendicular to the groove through the second elastic component, so that the separation shell is fastened with the inner cylinder 111, and the separation shell plays a role in connecting the second chamber 11 with the inner cylinder 111. When the airbag 110 is inflated and opened to expand, the two separated shells are separated from the main body by overcoming the abutting force of the second elastic part. In a specific application, the number of the separation shells is two, the two separation shells are respectively arranged at the outer side of the air bag 110, and the second elastic component adopts spring marbles.

As a possible implementation manner, as shown in fig. 1 to 2, a communication module is further disposed in the inner cylinder 111, and the photodetector 13 and the controller are communicatively connected through the communication module.

The communication module is arranged at the bottom of the inner cylinder 111 and is fastened to the lower end face of the battery compartment housing by screws. In a specific application, the communication module adopts optical fibers, one end of each optical fiber is connected with the carrier, and the other end of each optical fiber is connected with the controller. When the buoy 1 is detached from the carrier, communication is via optical fibres.

The embodiment of the invention also provides a flight line measuring system which comprises the buoy device.

The working process of the buoy device of the invention is as follows:

the first stage is as follows: when the buoy device reaches a certain set depth underwater under the dragging of the carrier, generally 10 meters underwater, a pressure sensor arranged on a controller senses the pressure, a signal is transmitted to the carrier through a cavity controller below a battery compartment, the buoy 1 is separated from the carrier, and meanwhile, the power supply of the buoy 1 is switched on.

And a second stage: the power supply is automatically connected with an air source, the air bag 110 is inflated through the air passage of the second chamber 11, and the air source controls the set value of air pressure and keeps the pressure stable. And after the inflation pressure reaches a set value, closing the electromagnetic valve and stopping inflating. If the air bag 110 leaks air midway, the pressure transmitter feeds back a signal to the controller, and the battery valve is opened at any time to supplement air.

And a third stage: during the inflation of the airbag 110, the volume is expanded under the action of air pressure, and the generated radial force pushes the separation shell hung outside the airbag 110 to the direction of increasing the diameter, so that the separation of the separation shell and the buoy 1 is realized.

A fourth stage: the buoyancy of the buoy 1 is increased, the second chamber 11 drives the first chamber 10 to rise together, and the trapezoidal guide rail fixed on the second chamber 11 moves upwards along the trapezoidal guide rail on the inner cylinder 111, so that the rising process is ensured to be stable.

The fifth stage: when the first chamber 10 and the second chamber 11 rise to the limited position, that is, the end surface of the inner end cover contacts the inner side of the upper end surface of the inner cylinder 111, the rising of the first chamber 10 and the second chamber 11 relative to the inner cylinder 111 stops, and the buoy 1 as a whole, including the first chamber 10, the second chamber 11 and the stern section, continues to rise.

The sixth stage: when the buoy 1 reaches the horizontal plane, a control signal is sent to the controller through the pressure sensor, the controller sends a signal to the air source, the air source is started, the air is inflated to the inner cylinder 111 through the air inlet on the inner end cover of the second chamber 11, and the set value is reached and the pressure is maintained. In the inflation process, when the inflation pressure exceeds the friction force between the photodetector 13 and the inner cylinder 111, the photodetector 13 rises along the inner hole of the inner cylinder 111, and the inner hole adopts double-sliding sealing, so that the sealing performance inside the inner cylinder 111 is ensured, and the inner cylinder also slides up and down.

A seventh stage: when the photoelectric detector 13 rises to a certain height, the photoelectric detector 13 contacts the first chamber 10, when the pushing force exceeds the friction force between the first chamber 10 and the inner cylinder 111, the first chamber 10 rises along the outer circle of the inner cylinder 111 until being separated from the inner cylinder 111, the first chamber 10 is thrown into the water through the elastic force of the elastic net 1002 on the first chamber 10, and the first chamber 10 and the elastic net 1002 are integrally separated from the buoy 1.

An eighth stage: when the photoelectric detector 13 rises to the right position, the locking head with the spring at the locking part is stretched and clamped in the locking groove of the inner cylinder 111 finally, and then the photoelectric detector 13 stops rising.

And a final stage: the photodetector 13 leaks out of the water surface, performs tracking, detection and the like of the target, and feeds back a signal to the controller.
