Description

Technical Field

[0001] The invention belongs to the technical field of ocean buoys, and in particular relates to an ocean buoy emergency positioning device and method. Background Art

[0002] A buoy is a kind of navigation mark floating on the water surface. It is anchored at a designated location and used to mark the scope of a waterway, indicate a shoal, an obstacle, or a surface navigation mark for a special purpose. Buoys are the most numerous and widely used among navigation marks. They are set in places where it is difficult or inappropriate to set up fixed navigation marks.

[0003] As an important means of marine environmental monitoring, the performance and stability of buoys are crucial. For example, the medium and large buoy devices mentioned in the Chinese invention patent entitled "Long-term online monitoring device and method for ocean cloud height based on buoys" (patent application number 201610645208.8) usually fix AIS equipment or net position meter on the top of the buoy to provide positioning services and provide location information for nearby fishing boats to prevent collisions. However, due to the complex marine environment, the installation platform on the buoy is easily hit by passing ships, resulting in damage to the platform and instrument failure. In addition, under extreme weather conditions, the buoy may drag anchor or capsize, causing the small platform on which the instrument is installed to enter the water and fail. On the other hand, if there is a problem with the buoy's buoyancy compartment, it may lead to insufficient buoyancy, resulting in the sinking of the buoy, causing the positioning equipment to fail to work properly and unable to effectively transmit positioning information. Especially in the context of frequent offshore fishing activities in my country, if complex sea conditions with low visibility such as heavy fog are encountered, the risk of collision between buoys and fishing boats increases, thereby affecting the normal operation of the marine monitoring and safety warning system.

[0004] Existing positioning devices, such as the Chinese utility model patent entitled "A net position meter for ships" (patent application number 2022227913704) and the Chinese invention patent entitled "A convenient net position meter" (application number 202111638183.6), directly fix the net position meter on a connecting plate or bamboo pole. When the buoy capsizes using the above devices, the positioning device fixed on the buoy will fall into the sea water as the buoy capsizes, resulting in the inability to obtain the positioning information of the buoy, thereby affecting the effectiveness of the ocean monitoring and safety warning system.

At the same time, a steel ball retaining ring and a shaft sleeve retaining ring are installed on the shaft sleeve.

The device uses a relatively redundant structure of two signal transmitting modules, combined with the mutual cooperation between the buoy attitude detection module and the automatic lifting module, to ensure that accurate position information can still be sent when an abnormal situation occurs in the buoy body, thereby facilitating emergency repair or salvage operations of the buoy.

[0021] In addition, a self-locking component is arranged in the automatic lifting module. Through the structural design between the locking cam, the limit rod and the switch spring, combined with the meshing structure between the transmission gear and the toothed disc, the gravity of the double-headed AIS net position meter is relied upon to make the locking cam, the transmission gear and the toothed disc engage with each other to achieve self-locking, which can fix the position of the double-headed AIS net position meter. When the double-headed AIS net position meter falls into the water to generate buoyancy or the watertight motor reverses, the locking cam can be disengaged from the transmission gear to achieve unlocking, thereby achieving the release of the connecting rope and avoiding obstruction of the movement of the double-headed AIS net position meter.

DETAILED DESCRIPTION

[0034] Embodiment 1

[0035] like Figure 1 As shown, an emergency positioning device for an ocean buoy comprises a buoy attitude detection module and an automatic lifting module installed on a buoy body 1, and a double-head AIS net position meter 8 is installed on the automatic lifting module.

[0036] like Figure 1 , Fig. 9As shown, the double-headed AIS net position meter 8 includes internal equipment and two relatively distributed signal transmission modules. The signal transmission module in this embodiment is an antenna, and the antenna is set at both ends to ensure that when the buoy body 1 is in different postures, at least one signal transmission module can be exposed to the water surface and transmit signals to transmit location information.

[0037] It should be noted that the AIS network position meter is a device based on the AIS (Automatic Identification System) protocol that reports the ship's own position information to the monitoring center. The working principle of the dual-head AIS network position meter 8 in this embodiment to realize the positioning function is the same as the working principle of the AIS network position meter in the prior art, which will not be repeated here.

[0038] The dual-head AIS net position meter 8 includes a single-head AIS mode and a dual-head AIS mode. Under normal circumstances, the dual-head AIS net position meter 8 is in the single-head AIS mode, and only one signal transmission module works to achieve normal positioning function. When the buoy attitude detection module detects that the attitude of the buoy body 1 is abnormal, the dual-head AIS net position meter 8 turns on the dual-head AIS mode, so that the two signal transmission modules work at the same time, thereby ensuring the continuity of the positioning signal transmission, transmitting the positioning information to the shore and surrounding ships, and providing accurate positioning for buoy maintenance, salvage operations and other operations.

[0039] like Figure 1 , Figure 2 As shown, the buoy attitude detection module includes an inertial measurement device, a data processing module and a communication module, wherein the inertial measurement device includes an accelerometer, a gyroscope, a magnetometer and a camera, and the inertial measurement device is used to monitor the attitude changes of the buoy body 1 in real time, and the monitoring content of the inertial measurement device includes the inclination angle, acceleration and rotation speed of the buoy body. The data processing module is used to receive the attitude data and video monitored by the inertial measurement device, and analyze the attitude and video of the buoy through an algorithm to determine whether it is damaged, overturned, sunk or other abnormal conditions. When the communication module detects that the attitude of the buoy body 1 is abnormal, it immediately transmits an emergency signal to the automatic lifting module, the double-headed AIS network position meter 8 and the base station.

[0040] After receiving the emergency signal, the automatic lifting module releases the connecting rope, so that the double-headed AIS net position meter 8 floats along the slide rail 401, so that at least one end of the double-headed AIS net position meter 8 is exposed to the water surface. After receiving the emergency signal, the double-headed AIS net position meter 8 starts the double-headed AIS module, so that the signal transmission modules at both ends work at the same time. The base station receives the emergency signal so that the staff can take emergency measures immediately.

[0041] like Figure 3As shown, the automatic lifting module includes a driving mechanism 3 and a lifting mechanism 4. The driving mechanism 3 is installed on the top deck of the instrument cabin of the buoy body 1. The instrument cabin of the buoy body 1 is provided with a slide rail channel, and the lifting mechanism 4 is installed in the slide rail channel. It should be noted that the driving mechanism 3 is installed beside the lifting mechanism 4, and the bracket 5 is located above the double-head AIS net position meter 8.

[0042] Specifically, Figure 4 As shown, the driving mechanism 3 includes a bracket 5, a winch assembly 6 and a watertight motor 7, and the winch assembly 6 and the watertight motor 7 are both installed on the bracket 5. Among them, a connecting rope is wound on the winch assembly 6, and the connecting rope is connected to the double-headed AIS net position meter 8. The watertight motor 7 drives the winch assembly 6 to rotate so that the connecting rope can be released or retracted in an orderly manner, and the position of the double-headed AIS net position meter 8 on the slide rail 401 is controlled by the length of the connecting rope.

[0043] like Figure 5 As shown, the bracket 5 includes a support plate 501, a mounting frame 502, a receiving plate 503, a rotating shaft 504 and a roller 505, wherein two support plates 501 are arranged opposite to each other, one of which is connected with a receiving plate 503 for supporting the winch assembly 6, and the other support plate 501 is provided with a through hole for supporting the watertight motor 7, and the watertight motor 7 is also supported by the mounting frame 502. Specifically, the support plate 501 includes a vertical portion and an inclined portion, the winch assembly 6 and the watertight motor 7 are installed on the vertical portion of the support plate 501, one end of the inclined portion of the support plate 501 is connected to the vertical portion, and the other end is inclined toward the lifting mechanism 4, and a rotating shaft 504 is installed, and a roller 505 is sleeved on the rotating shaft 504, and the rotating shaft 504 and the roller 505 are respectively provided with two upper and lower ones, and the connecting rope is transported through the double rollers above the bracket 5, which can reduce the friction between the connecting rope and the buoy body 1.

[0044] like Figures 6 to 8 As shown, the winch assembly 6 includes a rotating roller for winding the connecting rope, a support 601 and a self-locking assembly, and the rotating roller and the self-locking assembly are both mounted on the support 601. Among them, the rotating roller includes a disc 602 and a toothed disc 603 arranged opposite to each other, the toothed disc 603 is meshed with a transmission gear 608, and the transmission gear 608 is connected to the driving shaft of the watertight motor 7 through a coupling. The watertight motor 7 drives the transmission gear 608 to rotate, which can drive the toothed disc 603 to rotate, thereby realizing the release and retraction of the connecting rope.

[0045] The self-locking component can ensure that the winch assembly 6 remains in a self-locking state under normal circumstances, preventing the double-headed AIS network position meter 8 from being lowered due to misoperation in non-emergency situations, thereby affecting the positioning function of the double-headed AIS network position meter 8 under normal circumstances.

[0046] Specifically, Figure 7 , Figure 8As shown, the self-locking assembly includes an auxiliary rod 604, a locking cam 605, a limiting rod 606 and a switch spring 607. The locking cam 605 is installed on the support 601 through the auxiliary rod 604, and the protruding end of the locking cam 605 is engaged with the tooth block of the transmission gear 608, and the locking cam 605 is sleeved on the auxiliary rod 604. In addition, the support 601 is provided with a receiving groove at a position corresponding to the locking cam 605, and a switch spring 607 is arranged in the receiving groove. One end of the switch spring 607 is connected to the support 601, and the other end is connected to the limiting rod 606, and the limiting rod 606 is connected to the locking cam 605.

[0047] like Figure 7 The figure shows the initial state of the self-locking assembly. Under normal circumstances, the gravity of the double-headed AIS net position meter 8 is used to engage the toothed disc 603, the transmission gear 608, and the locking cam 605 to achieve self-locking. At this time, the switch spring 607 is in a stretched state. When an emergency occurs, the reverse rotation of the watertight motor 7 drives the transmission gear 608 to rotate, so that the locking cam 605 is disengaged from the transmission gear 608 to achieve unlocking. Then, the watertight motor 7 drives the transmission gear 608 to rotate normally, so that the rotating roller releases the connecting rope, which facilitates the displacement of the double-headed AIS net position meter 8.

[0048] In particular, since the self-locking component relies on the gravity of the double-headed AIS net position meter 8 to maintain the self-locking structure shown in the initial state, when the double-headed AIS net position meter 8 enters the sea water, the buoyancy of the double-headed AIS net position meter 8 destroys the balance of the self-locking state, and the self-locking component relies on the pulling force of the switch spring 607 to achieve automatic unlocking, avoiding hindering the double-headed AIS net position meter 8 from floating up by relying on buoyancy.

[0049] In addition, in order to improve the movement stability of the double-headed AIS net position meter 8, the double-headed AIS net position meter 8 is installed on the lifting mechanism 4 so that it can move up and down along the slide rail 401, so that the double-headed AIS net position meter 8 can slide smoothly along the predetermined path to avoid jamming or offset collision with the buoy body 1 during the floating process.

[0050] like Fig. 9 As shown, the double-headed AIS network position meter 8 is installed on a connecting frame 402, and a sliding sleeve 403 that cooperates with the sliding rail 401 is installed on the connecting frame 402. The double-headed AIS network position meter 8 moves up and down along the sliding rail 401 relying on the mutual cooperation between the sliding sleeve 403 and the sliding rail 401.

[0051] Specifically, Fig.10As shown, the sleeve 403 includes a sleeve seat 4031, a sleeve 4032, a steel ball retaining ring 4033, a steel ball 4034, and a sleeve retaining ring 4035. The sleeve 4032 is embedded in the sleeve seat 4031, and a steel ball groove for installing the steel ball 4034 is configured on the sleeve 4032. The steel ball 4034 is used to slide with the slide rail 401. At the same time, the sleeve 4032 is installed with a steel ball retaining ring 4033 and a sleeve retaining ring 4035 to limit the steel ball 4034 and the sleeve 4032 respectively.

[0052] Working principle: When the buoy body 1 is operating normally, the dual-head AIS net position meter 8 is in single-head AIS mode to provide conventional positioning functions. The buoy attitude detection module monitors the attitude of the buoy body 1 in real time. When the buoy body 1 is detected to be abnormal, the communication module will immediately send an emergency signal to the automatic lifting module, so that the automatic lifting module releases the connecting rope to facilitate the dual-head AIS net position meter 8 to float up;

[0053] At the same time, the communication module sends an emergency signal to the dual-head AIS network position meter 8, starts it to turn on the dual-head AIS mode, and makes the signal transmission modules at both ends work at the same time to ensure that the buoy body 1 is in different postures, and at least one signal transmission module is exposed above the water surface to realize the function of generating a signal; in addition, the communication module will also send an emergency signal to the land base to realize an emergency alarm and notify the shore personnel that there is a problem with the buoy and it needs urgent treatment.

[0054] Specifically, after receiving the emergency signal, the watertight motor 7 in the automatic lifting module first performs an unlocking operation, and then the watertight motor 7 drives the winch assembly 6 to release the connecting rope to prevent the connecting rope from hindering the movement of the double-headed AIS net position meter 8.

[0055] When it appears Figure 2 In the case of capsizing or sinking as shown, since the buoy body 1 is completely below the water surface, the double-headed AIS net position meter 8 automatically floats up to the surface of the water along the slide rail 401 according to its own buoyancy. Figure 2 As shown, when capsizing occurs, since the double-headed AIS net position meter 8 turns upside down together with the buoy body 1, the floating of the double-headed AIS net position meter 8 at this time will cause the signal transmitting module below the double-headed AIS net position meter 8 to be exposed to the water surface, thereby realizing the positioning signal sending function; when sinking occurs, the up and down positions of the double-headed AIS net position meter 8 do not change, and the floating of the double-headed AIS net position meter 8 at this time will cause the signal transmitting module above the double-headed AIS net position meter 8 to be exposed to the water surface, thereby realizing the positioning signal sending function.

[0056] If the buoy body 1 is hit and the following happens Figure 2In the damaged condition shown, the bracket 5 can shield the double-headed AIS network position meter 8 to a certain extent to prevent it from being damaged. Since the deck of the buoy body 1 is still above the water surface, after the self-locking component is unlocked, the double-headed AIS network position meter 8 will fall onto the water surface along the slide rail 401 by its own gravity. At this time, the signal transmitting module above the double-headed AIS network position meter 8 is exposed above the water surface to realize the positioning signal sending function. The double-headed AIS network position meter 8 is separated from the damaged buoy body 1, which can reduce the probability of the double-headed AIS network position meter 8 being damaged.

[0057] Embodiment 2

[0058] The structure of this embodiment is basically the same as that of the first embodiment, except that the internal equipment of the dual-head AIS network position meter 8 in this embodiment includes a mainboard, a positioning unit, a communication unit and an inertial measurement unit. The posture of the dual-head AIS network position meter 8 is monitored in real time by the inertial measurement unit. When the posture of the dual-head AIS network position meter 8 is abnormal, the communication unit sends the accurate position information output by the positioning unit to the base station or surrounding ships.

[0059] The dual-head AIS net position meter 8 also includes a solar panel and a rechargeable battery. The solar panel and the rechargeable battery cooperate with each other to provide long-term power supply for the dual-head AIS net position meter 8 in the marine environment.

[0060] Under normal circumstances, the dual-head AIS network position meter 8 is in single-head AIS mode, with only one signal transmission module working to achieve normal positioning function; when the buoy attitude detection module detects that the buoy body 1 has an abnormal attitude or the inertial measurement unit of the dual-head AIS network position meter 8 detects that the dual-head AIS network position meter 8 has an abnormal attitude, the main board is driven to turn on the dual-head AIS mode, so that the two signal transmission modules work at the same time, thereby ensuring the continuity of positioning signal transmission, transmitting positioning information to the shore and surrounding ships, and providing accurate positioning for buoy maintenance, salvage operations, etc.

[0061] Embodiment 3

[0062] The structure of this embodiment is basically the same as that of the first embodiment, except that this embodiment further includes a power supply module for supplying power to the buoy attitude detection module and the automatic lifting module. Figure 1 As shown, the power supply module includes a power controller, a solar panel and a rechargeable battery. Figure 3As shown, the solar panel is tiltedly installed on the top platform of the buoy body 1, and the power controller and the rechargeable battery are installed in the instrument compartment at the bottom of the buoy body 1. The power controller is used to adjust between the solar panel and the rechargeable battery to prevent the battery from being overcharged or discharged, and provides the maximum power point tracking function. At the same time, it is responsible for regulating the corresponding current and voltage to the buoy attitude detection module and the automatic lifting module to realize power supply. Among them, the capacity of the rechargeable battery is selected according to the power consumption demand of the buoy body 1, and no specific restrictions are made here.
