Technical Field

[0001] This invention relates to the field of navigation aids technology, and more specifically to a mobile navigation aid that is easy to deploy. Background Technology

[0002] Ships can sink in calm waters such as anchorages or waterways due to malfunctions or accidents. Sunken ships cannot be salvaged in a short time, or salvage efforts are abandoned due to funding issues. Sunken ships pose a safety threat to passing vessels, and there is currently a lack of corresponding measures to prevent this from happening. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a mobile navigation beacon that is easy to deploy.

[0004] To achieve the above objectives, the present invention provides a mobile navigation beacon that is easy to deploy, comprising a lower pole and an upper pole fixed to the upper end of the lower pole. The lower pole has a hollow structure, and a float is fixed to its outer upper end. The float has a drum and a pulley assembly inside, and a traction rope is provided on the drum. The upper end of the lower pole has an opening, and the outer end of the traction rope passes around the pulley assembly, passes through the opening into the lower pole, and exits from the lower end of the lower pole. The outer end of the traction rope is fixedly connected to a magnet. An AIS position reporting terminal is fixed to the upper end of the upper pole.

[0005] Furthermore, the pulley assembly includes a mounting block fixed inside the buoy, a first pulley is provided in the middle of the mounting block and a connecting column is fixed at its upper end, a mounting part is provided at the outer end of the connecting column, a second pulley is provided on the lower side of the mounting part, and a third pulley is provided on the lower side of the top of the buoy outside the opening.

[0006] Furthermore, a connecting sleeve is slidably connected to the outer side of the connecting column, a fourth pulley is provided on the lower side of the connecting sleeve, and a spring is provided between the fourth pulley and the mounting part. A knife holder is fixedly connected to the outer end of the connecting sleeve, and a blade is fixed to the lower end of the knife holder. A knife groove is provided on the mounting block to accommodate the blade, and the knife groove is spaced apart on the upper side of the first pulley.

[0007] Furthermore, a plurality of connecting plates are fixed to the lower end of the lower rod body, and an end plate is fixedly connected to the lower end of the connecting plate. The upper side of the magnet is provided with a groove that mates with the end plate.

[0008] Furthermore, there are three connecting plates, with an included angle of 120° between any two adjacent connecting plates, and the lower end of each connecting plate is inclined outward.

[0009] Furthermore, the outer side of the middle portion of the connecting plate is fixedly connected to a connecting ring.

[0010] Furthermore, a connecting frame is fixedly connected to the lower end of the upper rod, and two handles are fixedly connected to the upper side of the connecting frame.

[0011] Furthermore, the AIS location reporting terminal includes a battery and a main control board that can be housed within the housing.

[0020] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solutions of the present invention, and it should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0021] like Figures 1 to 6 As shown, this embodiment of the invention provides a mobile navigation beacon that is easy to deploy, including a lower rod 1 and an upper rod 2, wherein the upper rod 2 is fixed to the upper end of the lower rod 1. The outer diameter of the lower rod 1 is preferably larger than that of the upper rod 2. The lower rod 1 is heavier, ensuring a low center of gravity and preventing tipping during use. It has a hollow internal structure. A float 3 is fixed to the outer side of the upper end of the lower rod 1. Preferably, a through hole is provided in the middle of the float 3, through which the lower rod 1 passes. A limiting plate is provided on the upper and lower sides of the float 3, respectively. The middle part of the limiting plate is welded to the lower rod 1. The limiting plate and the float 3 can be fixed by adhesive or other methods to ensure the airtightness of the float 3. A limiting structure can also be provided between the limiting plate and the float 3 to prevent the float 3 from rotating. Inside the float 3, there is a drum 4 and a pulley assembly. The drum 4 is rotatably set in the middle of the float 3. A traction rope 5 is provided on the drum 4. An opening 6 is provided at the upper end of the lower rod 1. The outer end of the traction rope 5 is set around the pulley assembly and passes through the opening 6 into the lower rod 1 and out from the lower end of the lower rod 1. The outer end of the traction rope 5 is fixedly connected to a magnet 100. An AIS position reporting terminal 7 is fixed at the upper end of the upper rod 2.

[0022] When using this device, first determine the location of the sunken ship to which you want to set the device. Then, pull out the towing rope 5, leave the distance mentioned above plus the reserved length, cut off the excess, and then fix it to the magnet 100. After that, drop the magnet 100 into the water and it will be attracted to the sunken ship. At this time, the device can be kept in the upper area of ​​the sunken ship. The location of the sunken ship can be reported through the AIS location reporting terminal 7, so that other ships under navigation can observe the location information of the sunken ship through the AIS equipment.

[0023] The pulley assembly of this embodiment includes a mounting block 8 fixed inside the float 3. A first pulley 9 is provided in the middle of the mounting block 8. A connecting column 10 is fixed at the upper end of the mounting block 8. A mounting part 11 is provided at the outer end of the connecting column 10. A second pulley 12 is provided on the lower side of the mounting part 11. A third pulley 13 is provided on the lower side of the top of the float 3 outside the opening 6. The outer end of the traction rope 5 passes sequentially around the first pulley 9, the second pulley 12 and the third pulley 13 and enters the lower rod body 1 through the opening 6.

[0024] Because the magnet 100 used has a strong adsorption force, in actual use, the sunken ship may gradually sink into the silt. When the sinking depth exceeds the reserved length, it may drag the device into the water. As a preferred embodiment, a connecting sleeve 14 is preferably slidably connected to the outside of the connecting column 10. A fourth pulley 15 is provided on the lower side of the connecting sleeve 14. A spring 16 is provided between the connecting sleeve 14 and the mounting part 11. A knife holder 17 is fixedly connected to the outer end of the connecting sleeve 14. The lower end of the knife holder 17 extends outward and downward. The two sides of the knife holder 17 are spaced apart on both sides of the mounting block 8. A blade 18 is fixed at the lower end of the knife holder 17. A knife groove 19 is provided on the mounting block 8 to accommodate the blade 18. The knife groove 19 is spaced apart on the upper side of the first pulley 9. The spring 16 is kept in a compressed state. During use, the traction rope 5 on the drum 4 is fully extended. When the traction rope 5 is not under tension, the connecting sleeve 14 is at its outermost end, and the blade 18 is in the cutter groove 19, not in contact with the traction rope 5. When the external tension on the traction rope 5 exceeds the current elastic force of the spring 16, the spring 16 will be further compressed. At this time, the traction rope 5 will pull the connecting sleeve 14 inward, and the blade 18 will move inward simultaneously, thus moving out of the cutter groove 19. When the set tension is reached, the blade 18 will contact the traction rope 5 above the first pulley 9 and cut the traction rope 5, causing the device to detach from the traction rope 5, preventing it from sinking into the water together. Furthermore, since the AIS position reporting terminal 7 has a positioning reporting function, it is also convenient for later retrieval. Additionally, the traction rope 5 can be made of easily cut ropes such as nylon rope. To ensure counterweight balance, a counterweight block can be installed in the float 3 on the opposite side of the mounting block 8.

[0025] To prevent the traction rope 5 from completely slipping out when not in use, several connecting plates 20 are fixed to the lower end of the lower rod body 1. An end plate 21 is fixedly connected to the lower end of each connecting plate 20. A groove is provided on the upper side of the magnet 100 to mate with the end plate 21. When not in use, the magnet 100 is attracted to the end plate 21, preventing the traction rope 5 from being stressed. Preferably, there are three connecting plates 20, with an angle of 120° between any two adjacent connecting plates 20. The lower ends of the connecting plates 20 are inclined outwards. To improve stability, a connecting ring 22 is also fixedly connected to the outer middle part of the connecting plate 21.

[0026] To facilitate lifting and lowering, a connecting frame 23 is fixedly connected to the lower end of the upper rod 2. The connecting frame 23 can be fixedly connected to the upper rod 2 by welding to the outside of the aforementioned limiting plate. Two handles 24 are fixedly connected to the upper side of the connecting frame 23, allowing one or two people to lift the device using the two handles 24.

[0027] The principle of the AIS location reporting terminal 7 in this embodiment of the invention is the same as that of the existing network positioning instrument. It includes a battery 71 and a main control board, both housed within the casing. The main control board includes a processor 72 connected to the battery 71. The processor 72 is connected to an FSK modulator 73 and a positioning module 74, respectively. The FSK modulator 73 is connected to a power amplifier circuit 75, which is connected to an antenna. The positioning module 74 collects the location information of the sunken ship and sends it to the processor 72 for framing. The processor 72 can be a GD32E230, and the FSK modulator 73 can be a Si4463, to implement the waveform modulation function of AIS, generating a low-power AIS modulated signal. Finally, the power amplifier circuit 75 generates a 5W signal, which is then transmitted through the antenna. To avoid frequent replacement of the battery 71, the casing is transparent, and a solar panel is installed inside. The solar panel is connected to the battery 71 through a charging control circuit on the main control board to charge the battery 71 using solar energy.

[0028] The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, other parts not specifically described are existing technology or common knowledge. 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.
