Description

Technical Field

[0001] This invention relates to the field of remote rescue technology, specifically to an unmanned surface vessel (USV) automatic remote cable-throwing device. Background Technology

[0002] In scenarios such as maritime rescue, water operations, and unmanned surface vessels autonomously performing missions, it is often necessary to quickly and accurately throw rescue supplies, equipment, or signal cables to the target location. Traditional cable throwing methods often rely on manual operation, which is not only inefficient, but also cannot fully guarantee the safety of operators in bad sea conditions or emergency situations. In addition, in recent years, with the rapid development of unmanned technology, unmanned surface vessels (USVs) have been used more and more widely in maritime rescue and water operations. However, existing USV cable throwing systems often use robotic arms or catapults to launch cables, but these methods usually require complex control systems and high costs. Furthermore, most existing cable throwing systems lack flexible launching angle adjustment functions and cannot adjust the launching direction of the cable according to different situations, which limits their application in complex rescue scenarios. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-5 The present invention provides a technical solution comprising: a mounting base 1, an adjusting unit 2 connected to one side of the mounting base 1, lateral supports 3 connected to both sides of the top of the adjusting unit 2, a main control housing 4 rotatably mounted between the lateral supports 3, an integrated plate 5 connected to one side of the main control housing 4, a pneumatic system connected to one side of the integrated plate 5, a high-pressure gas cylinder 7 and a traction component 18 connected to one side of the pneumatic system, a launch tube 17 connected to one side of the integrated plate 5, a base frame 13 connected to one side of the integrated plate 5, a triggering unit connected to the bottom of the base frame 13, connecting plates 201 rotatably mounted on the opposite sides of the lateral supports 3, rope compartments 202 connected to one side of each connecting plate 201, a network relay 11 connected to the back of the main control housing 4, and an integrated control module 12 internally connected to the main control housing 4, the integrated control module 12 including a battery (i.e., a remote control receiver), a manual pressure relief valve 203 connected to the top of the integrated plate 5, and the network relay 11 electrically connected to the pneumatic system, the triggering unit, and the adjusting unit 2; Reference Figure 1 and Figure 2 As shown, the regulating unit 2 includes a fixed plate 21 fixedly mounted on one side of the mounting base 1. The fixed plate 21 is fixedly mounted on one side of the mounting base 1 by bolts. A rotating plate 22 is rotatably mounted on the top of the fixed plate 21. A rotating shaft is connected between the rotating plate 22 and the fixed plate 21. Two sets of guide bolts 23 are connected to the bottom of the rotating plate 22, with two guide bolts in each set. An arc-shaped hole 111 is opened on the top surface of the fixed plate 21. An electric push rod 24 is rotatably mounted on the bottom of the fixed plate 21. The bottom end of one of the guide bolts 23 passes through the arc-shaped hole 111 and is rotatably connected to the electric push rod 24. An electric push rod 25 is rotatably mounted on the top of the rotating plate 22. An elevation angle frame 26 is rotatably mounted on the top of the electric push rod 25. By controlling the extension or retraction of the electric push rod 24, the guide bolts 23 are driven to slide along the arc-shaped hole 111, thereby adjusting the direction of the rotating plate 22 above, and thus adjusting the projection direction of the device. By controlling the extension or retraction of the electric push rod 25, the elevation angle frame 26 is pushed to rotate, thereby adjusting the projection angle.

[0017] Reference Figure 1 As shown, one end of the elevation frame 26 is rotatably equipped with a round shaft, both ends of which are rotatably connected to the side support 3 and are rotatably equipped with connecting bolts. The connecting bolts are fixedly installed at the bottom of the main control housing 4. The other end is connected to a positioning bracket 19, and the top of the positioning bracket 19 is connected to an auxiliary positioning bracket 20. The launch tube 17 and the high-pressure gas cylinder 7 are located between the positioning bracket 19 and the auxiliary positioning bracket 20. The traction component 18 is located inside the launch tube 17. The elevation frame 26 can adjust the angle and also assist in supporting and fixing the high-pressure gas cylinder 7 and the launch tube 17, further ensuring the stability of the overall device.

[0018] Reference Figure 4 and Figure 5 As shown, the pneumatic system includes a quick connector 6 and a locking connector 8 connected to one side of the integrated plate 5. A connecting frame 9 is connected to the back of the integrated plate 5, and a main air valve 10 is connected to the top of the connecting frame 9. The locking connector 8 is connected to the trigger unit. An air passage is opened in the connecting frame 9, and the two ends of the air passage are respectively connected to the quick connector 6 and the locking connector 8. The manual pressure relief valve 203 is connected to the quick connector 6. Through the quick connector 6 and the locking connector 8, the high-pressure gas cylinder 7 and the traction component 18 can be quickly and conveniently connected and installed. After the main air valve 10 is opened, the high-pressure compressed gas in the high-pressure gas cylinder 7 will enter the traction component 18 through the main air valve 10 to complete the gas charging inside the traction component 18. The manual pressure relief valve 203 located above the integrated plate 5 plays a safety protection role.

[0019] Reference Figure 5As shown, the trigger unit includes a protective housing 14 fixedly installed at the bottom of the base frame 13. A transfer valve 15 is connected between the protective housing 14 and the base frame 13. A fork linkage rod 151 is connected to the output end of the transfer valve 15. A fork 16 is connected to one end of the fork linkage rod 151. One side of the fork 16 is connected to the locking joint 8. While charging the inside of 18, the transfer valve 15 is also charged and pressurized. After the pressurization is completed, the transfer valve 15 moves the fork 16 through the fork linkage rod 151, thereby disconnecting the connection between the locking joint 8 and the traction component 18. High-pressure gas will be quickly ejected through the traction component 18, thereby pushing the traction component 18 out of the launch tube 17 and driving the throwing cable towards the shore.

[0020] Reference Figure 5 As shown, the traction assembly 18 includes an aluminum alloy inner liner 181, with a rubber coating layer 182 attached to the surface of the aluminum alloy inner liner 181. A nozzle 183 is connected to one end of the aluminum alloy inner liner 181, and a manual air valve is connected to one side of the nozzle 183. The nozzle 183 is connected to the locking joint 8, and a throwing cable is connected to one side of the rubber coating layer 182. When not in use, the throwing cable is collected and placed in the rope compartment 202. The aluminum alloy inner liner 181 is quickly connected to the locking joint 8 through the nozzle 183. After charging is completed, the locking joint 8 is opened, and the compressed air inside the aluminum alloy inner liner 181 is ejected from the nozzle 183, pushing the aluminum alloy inner liner 181 out. The rubber coating layer 182 provides a protective effect when the aluminum alloy inner liner 181 falls. In the first stage, the main air valve 10 is opened to inflate the traction assembly 18. At this time, the compressed gas in the high-pressure gas cylinder 7 is released into the hollow traction assembly 18 through the air passage in the connecting frame 9. At this time, the traction assembly 18 and the locking joint 8 are locked, and the traction assembly 18 has already carried the launch kinetic energy. In the second step, the transfer air valve 15 is activated. The front air passage of the transfer air valve 15 is connected to the air passage of the traction assembly 18. When the main air valve 10 is opened, the front end of the transfer air valve 15 is pressurized. The transfer air valve 15 opens and releases pressure, pushing the shift fork linkage rod 151 and the shift fork 16 to move, instantly unlocking the locking joint 8. The traction assembly 18 is propelled out by compressed air ejected through the nozzle 183, completing the cable throwing action.

[0021] The implementation principle of this application is as follows: In use, the injection angle of the launch tube 17 is adjusted by regulating the unit. The main air valve 10 is opened, and compressed air from the high-pressure gas cylinder 7 enters the traction component 18, which is connected to one end of the latch joint 8, through the air passage in the connecting frame 9. This also pressurizes the transfer valve 15. After charging is complete, the transfer valve 15 is opened, and the fork 16 is moved via the fork linkage rod 151, unlocking the latch joint 8's positioning connection to the traction component 18. The compressed gas in the traction component 18 is ejected through the nozzle 183, thus ejecting the traction component 18 from the launch tube 17, carrying the throwing cable to complete the launching action, and quickly releasing the cable from the cable magazine. The 202 system includes two sets of components: the towing assembly 18, the high-pressure gas cylinder 7, the pneumatic system, and the trigger unit. If the first launch fails to reach the target position or is affected by external factors, the second set can be used to launch again, ensuring the cable launch effect. During remote rescue, remote control commands transmitted from the network relay 11 can be used to open or close the main gas valve 10 and the branch gas valve 15 to control the launch of the cable. When the unmanned surface vessel approaches the shore, the towing assembly 18 is launched remotely when it is about 20 meters from the shore. The towing assembly 18 carries the cable (5mm diameter) and is launched. The cable is then manually pulled out and fixed to the bollard. One type is a handheld remote control, which can send control commands to the integrated control module 12 to trigger the device to throw the rope. It allows for close-range operation with a remote control distance of 150 meters. The other type is a network remote control, which can be remotely controlled via a local area network and network relay 11, with no distance limit. In situations where the unmanned surface vessel is docked at a relatively close distance, the remote control signal is easily interfered with or a single system may malfunction during actual operation. In such cases, the backup system will immediately start transmitting.
