[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] When the existing buoy is used to measure the route, the measurement trajectory is inaccurate because the carrier and the buoy are inseparable.

[0026] In view of the above technical problems, an embodiment of the present invention provides a buoy device, such as Figures 1 to 3As shown, it includes: a carrier 2 and a buoy 1, the carrier can be separated from the buoy 1, and the buoy 1 includes a first chamber 10, a second chamber 11, a third chamber 12 and a photoelectric detector 13; wherein, a buckling portion is arranged at the head of the photoelectric detector 13; 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 portion is arranged on the inner wall of the first chamber 10; the snap ring is snapped with the buckling portion to make the photoelectric detector 13 buckle with the first chamber 10; the second chamber 11 is respectively connected with the first chamber 10 and the inner cylinder 111, and is used to accommodate the bottom of the photoelectric detector 13; an airbag 110 is arranged on the outer wall of the second chamber 11, and when the airbag 110 is inflated, its buoyancy can make the buoy 1 float; a controller is arranged in the inner cylinder 111, and the controller is used to control the floating speed of the buoy 1.

[0027] It should be noted that the carrier of the buoy device in this embodiment is separable from the buoy 1. In specific applications, after the buoy device is thrown into the water, it floats upward by the power provided by the air source of the buoy device. When the buoy device rises to a preset height, the controller sends a control signal to separate the carrier from the buoy 1.

[0028] In this embodiment, the position of the buoy device in the water is sensed by a pressure sensor. When the buoy device descends to 10 meters underwater, the carrier is separated from the buoy 1.

[0029] In an alternative manner, such as Figure 2 As shown, the first chamber 10 is connected to the second chamber 11 by using a double sealing ring structure.

[0030] By adopting the above connection mode, the first chamber 10 is used to protect the photoelectric detector 13 and prevent the photoelectric detector 13 from being corroded and damaged by seawater in a non-working state.

[0031] In an alternative manner, such as Figure 2 As shown, the second chamber 11 contains an inner cylinder 111, and the lower end of the inner cylinder 111 is assembled with the inner end cover to form a sealed cavity, and the upper end is connected to the photoelectric detector 13 through a double sealing ring sliding sealing structure.

[0032] With the above connection method, the second chamber 11 has both sealing properties and the photodetector 13 is movable during operation. 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 .

[0033] In an alternative manner, such as Figure 2 As shown, the airbag 110 is fixed by a hoop on the outside of the inner cylinder 111, and two semicircular separation shells are arranged on the outer wall of the airbag 110.

[0034] By adopting the above technical solution, a semicircular detachable shell is used to ensure the streamline structure of the buoy device in the water and reduce the water resistance; at the same time, the airbag 110 is folded when not in use, and the semicircular detachable shell can protect the airbag 110. In addition, the folded state of the airbag 110 when not in use can reduce the overall volume of the buoy device.

[0035] In an alternative manner, such as Figure 2 As shown, the second chamber 11 and the inner cylinder 111 are connected by a trapezoidal guide rail.

[0036] By adopting the above technical solution, the trapezoidal guide rail can realize relative sliding between the second chamber 11 and the inner cylinder 111. When the inner cylinder 111 in the second chamber 11 moves upward, the trapezoidal guide rail will play a guiding role and also lower the center of mass of the buoy 1 when it floats up, thereby solving the problem of stabilizing the floating posture.

[0037] In the buoy device provided by the embodiment of the present invention, the buoy 1 of the present invention and the carrier can be separated, so that the buoy device can be placed at a specific location to achieve track measurement or target tracking at a specific location. A photoelectric detector 13 is arranged in the buoy 1 for achieving target tracking or track measurement. Since an air bag 110 is arranged on the outer wall of the second chamber 11, the air bag 110 will drive the buoy 1 to float up; since a buckle and part are arranged on the head of the photoelectric detector 13, when the photoelectric detector 13 floats into the first chamber 10, it is buckled with the snap ring in the first chamber 10, effectively protecting the photoelectric detector 13, avoiding the photoelectric detector 13 from colliding with the first chamber 10 and being damaged, so that subsequent measurements are more accurate. At the same time, by inflating the air bag 110 arranged outside the second chamber 11, the carrier and the buoy 1 are separated, and the buoy 1 floats to the horizontal plane under the action of buoyancy, and the photoelectric detector 13 is started to perform route measurement and target tracking. The buoy device of the present invention has the advantages of flexible operation and accurate testing.

[0038] As a possible implementation, Figures 1 to 3 As shown, the photodetector 13 further includes a locking portion, which is disposed at the bottom of the photodetector 13 and is used to fix the photodetector 13 to the second chamber 11 .

[0039] In an optional manner, the locking portion is installed at the bottom of the photoelectric detector 13 and is clamped in the locking groove of the inner cylinder 111 through a lock head.

[0040] In specific application, the gas source inflates the second chamber 11 so that the second chamber 11 is in a floating state. When the photoelectric detector 13 rises to the calibrated height, it can be mechanically self-locked, the photoelectric detector 13 stops rising, and starts working. The locking part can effectively prevent the photoelectric detector 13 from sinking.

[0041] As a possible implementation, Figures 1 to 3 As shown, the first elastic component 100 is an elastic net 1002 .

[0042] In order to ensure that the photoelectric detector 13 can work smoothly when the buoy 1 floats to the water surface, an elastic net 1002 is installed inside the first chamber 10 by fastening with screws.

[0043] The elastic force of the elastic net 1002 can ensure reliable separation of the first chamber 10 and the second chamber 11, and effectively avoid collision between the photoelectric detector 13 and the first chamber 10 when the photoelectric detector 13 rises.

[0044] When the photoelectric detector 13 rises into the first chamber 10, it touches the elastic net 1002, and the elastic net 1002 is deformed. When the photoelectric detector 13 rises to the maximum deformation point of the elastic net 1002, the elastic net 1002 will pop the first chamber 10 out of the water, and the photoelectric detector 13 starts working.

[0045] As a possible implementation, Figure 3 As shown, at least one elastic band 1001 is provided on the elastic net 1002 , and one end of the at least one elastic band 1001 is connected to the elastic net 1002 1002 , and the other end is fixedly connected to the first chamber 10 .

[0046] In this embodiment, the elastic net 1002 can be stretched in any direction, ensuring that when the photoelectric detector 13 contacts the elastic net 1002 in any direction, the elasticity of the elastic net 1002 can buffer and protect the photoelectric detector 13 .

[0047] As a possible implementation, Figures 1 to 2 As shown, a power source and a gas source are also provided in the inner cylinder 111 . The power source is used to provide electrical energy to the photoelectric detector 13 , and the gas source is used to provide gas to the airbag 110 and the second chamber 11 .

[0048] 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 surfaces are fastened by screws through two sealed end covers, and have a sealing effect, and the upper cavity annular groove is equipped with a power supply, and in specific applications, a battery is used for power supply. Two layers of control boards are also supported and fixed in the inner cylinder 111 by two supports; there is also a non-sealed cavity in the middle part for placing the gas source and the controller, and the gas nozzle on the gas source is connected to the second chamber 11 through the gas path, one gas path is directly connected to the inner end cover on the second chamber 11 to the inner cylinder 111, and the other gas path is connected to the airbag 110 through the inner end cover and the gas path.

[0049] As a possible implementation, Figures 1 to 2As shown, a detachable shell is provided on the outer wall of the airbag 110 , and the detachable shell is detachably connected to the second chamber 11 via a second elastic component.

[0050] In an optional manner, one end of the separation shell is stuck in the groove of the inner cylinder 111, and the other end is stuck in the groove of the bottom shell in the inner cylinder 111, and is tightened in the vertical direction of the groove by a second elastic component, so that the separation shell and the inner cylinder 111 are fastened together, and the separation shell plays a connecting role between the second chamber 11 and the inner cylinder 111. When the airbag 110 is inflated and expanded, the two separation shells are separated from the main body by overcoming the tightening force of the second elastic component. In specific applications, there are two separation shells, which are respectively arranged on the outside of the airbag 110, and the second elastic component uses a spring ball.

[0051] As a possible implementation, Figures 1 to 2 As shown, a communication module is also provided in the inner cylinder 111, and the photoelectric detector 13 and the controller are communicatively connected via the communication module.

[0052] The communication module is arranged at the bottom of the inner cylinder 111 and is fastened to the lower end surface of the battery compartment housing by screws. In a specific application, the communication module uses an optical fiber, one end of which is connected to the carrier and the other end is connected to the controller. When the buoy 1 is separated from the carrier, communication is performed through the optical fiber.

[0053] An embodiment of the present invention further provides a route measurement system, comprising the above-mentioned buoy device.

[0054] The working process of the buoy device of the present invention is as follows:

[0055] Phase 1: When the buoy device reaches a certain set depth underwater under the drag of the carrier, generally 10 meters underwater, the pressure sensor installed on the controller senses it and transmits the signal to the carrier through the controller in the lower cavity of the battery compartment. The buoy 1 is separated from the carrier and the power of the buoy 1 is turned on at the same time.

[0056] The second stage: the power supply automatically connects to the gas source, and the airbag 110 is inflated through the gas path of the second chamber 11. The gas source controls the air pressure setting value and keeps the pressure stable. When the inflation pressure reaches the set value, the solenoid valve is closed and inflation stops. If the airbag 110 leaks during the process, the pressure transmitter feeds back the signal to the controller, and the battery valve is opened at any time to replenish gas.

[0057] The third stage: during the inflation process of the airbag 110 , the volume expands under the action of air pressure, and the radial force generated pushes the separation shell attached to the outside of the airbag 110 in the direction of increasing diameter, thereby achieving the separation of the separation shell and the buoy 1 .

[0058] Stage 4: The buoyancy of the buoy 1 increases, and the second chamber 11 drives the first chamber 10 to begin to rise together. The trapezoidal guide rail fixed on the second chamber 11 moves upward along the trapezoidal guide rail on the inner cylinder 111 to ensure a smooth rising process.

[0059] The fifth stage: when the first chamber 10 and the second chamber 11 rise to a 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 rise 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.

[0060] Stage 6: When the buoy 1 reaches the horizontal plane, the pressure sensor sends a control signal to the controller, and the controller sends a signal to the gas source and starts the gas source to inflate the inner cylinder 111 through the air inlet on the inner end cover of the second chamber 11 to reach the set value and maintain the pressure. During the inflation process, when the inflation pressure exceeds the friction between the photoelectric detector 13 and the inner cylinder 111, the photoelectric detector 13 rises along the inner hole of the inner cylinder 111. The inner hole adopts a double sliding seal to ensure the sealing of the inner cylinder 111 and slide up and down.

[0061] The seventh stage: when the photoelectric detector 13 rises to a certain height, the photoelectric detector 13 contacts the first chamber 10. When the thrust exceeds the friction 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 it separates from the inner cylinder 111. The elastic force of the elastic net 1002 on the first chamber 10 throws the first chamber 10 into the water, and the first chamber 10 and the elastic net 1002 are separated from the buoy 1 as a whole.

[0062] The eighth stage: when the photoelectric detector 13 rises to the right position, the locking head with the spring of the locking part is stretched and retracted, and finally stuck in the locking groove of the inner cylinder 111, and then the photoelectric detector 13 stops rising.

[0063] The final stage: the photoelectric detector 13 emerges from the water surface to track and detect the target, and feeds back the signal to the controller.

[0064] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
