Description

Technical Field

[0001] The utility model relates to an automatic recovery device for an unmanned boat. Background Art

[0002] In recent years, due to the maneuverability of unmanned boats (UAVs), they have been able to operate in waters far beyond the reach of manned boats. With their widespread use, the deployment and recovery of UAVs during operations has become a pressing issue. Due to factors such as the operating environment and sea conditions, the deployment and recovery of UAVs often face various risks and challenges. Previously, manual operations required the use of support boats, and recovery was sometimes impossible. To mitigate the risks associated with the deployment and recovery of UAVs, a safe and reliable deployment and recovery method is needed. Similar devices already exist, but existing recovery devices lack an effective response in the event of an UAV losing control or traveling too fast. This can result in the UAV potentially colliding with the recovery device when entering, potentially damaging both the UAV and the recovery device. Furthermore, since the opening of the recovery device lacks a protective device, this can also cause scraping between the UAV and the recovery device. Utility Model Content

[0003] The utility model provides an automatic recovery device for an unmanned boat, which can effectively solve the above problems.

[0004] The utility model is achieved in this way:

[0005] An automatic recovery device for an unmanned boat comprises an enclosure frame, a front blocking frame, a connecting belt, an upper pulling frame, connecting wings, a rope, and a buoyancy member. The front blocking frame is movably connected to the enclosure frame, the upper pulling frame is connected to the enclosure frame via the connecting wings and the connecting belt, the rope is fixed at both ends of the upper pulling frame, and the buoyancy member is arranged at the edge of the enclosure frame to increase the buoyancy of the recovery device.

[0006] It also includes a first connecting section and a second connecting section connected to the front blocking frame;

[0007] An upper connecting assembly is disposed inside the enclosure frame and is used to connect to the front blocking frame; the upper connecting assembly includes an upper bracket, a slider slidably disposed inside the upper bracket, an elastic member fixedly connected to one side of the slider, and a pulling member fixedly connected to the other side of the slider. A limit block is fixedly disposed inside the upper bracket and located in front of the slider, and a rubber pad is fixedly disposed on the limit block.

[0008] Among them, one end of the pulling member is connected to the first connecting section on the front blocking frame, so that when the unmanned boat collides with the recovery device, the front blocking frame and the upper connecting assembly cooperate with each other, thereby reducing the impact force of the unmanned boat.

[0009] As a further improvement, it also includes a positioning mechanism, which includes a folding piece, and the folding piece further includes a fixed block arranged on the enclosure frame, an axis rod arranged between the fixed blocks, a torsion spring wound around both ends of the axis rod, and a positioning plate connected to one end of the torsion spring.

[0010] As a further improvement, a positioning flap is provided on the outer wall of the shaft, connecting rods are provided at the upper and lower ends of the positioning flap, and a roller is rotatably provided between the two connecting rods.

[0011] As a further improvement, the connecting belt is made of spandex or composite elastic fiber.

[0012] As a further improvement, the enclosure frame and the upper bracket in the upper connecting assembly are both movably connected to the front blocking frame.

[0013] As a further improvement, receiving plates for connecting to the unmanned boat are symmetrically provided on the inner edge of the enclosure frame.

[0014] As a further improvement, a buffer pad is also provided on the front blocking frame to provide a buffering effect for the unmanned boat.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0030] Reference Figure 1-4As shown, an automatic recovery device for an unmanned boat includes an enclosure frame 1, a front blocking frame 3, a connecting belt 4, an upper pulling frame 5, a connecting wing 6, a rope 7 and a buoyancy member 8. The front blocking frame 3 and the enclosure frame 1 are movably connected, the upper pulling frame 5 is connected to the enclosure frame 1 through the connecting wing 6 and the connecting belt 4, the rope 7 is fixed at both ends of the upper pulling frame 5, and the buoyancy member 8 is arranged on the edge of the enclosure frame 1 to increase the buoyancy of the recovery device.

[0031] When recovering the unmanned boat, the connecting wings 6 on the upper pulling frame 5 are connected to the recovery structure through the connecting belt 4, and the two ends of the upper pulling frame 5 are connected to the traction device through the rope 7, thereby recovering the unmanned boat.

[0032] The front blocking frame 3 includes a first connecting section 30 and a second connecting section 31 connected to the front blocking frame 3 .

[0033] The upper connecting assembly 2 is disposed inside the enclosure frame 1 and is used to connect to the front blocking frame 3. The upper connecting assembly 2 includes an upper bracket 20, a slider 21 slidably disposed inside the upper bracket 20, an elastic member 22 fixedly connected to one side of the slider 21, and a pulling member 23 fixedly connected to the other side of the slider 21. A limit block 24 is fixedly disposed inside the upper bracket 20 and located in front of the slider 21, and a rubber pad 25 is fixedly disposed on the limit block 24.

[0034] It should be noted that the enclosure frame 1 and the upper bracket 20 in the upper connecting assembly 2 are both movably connected to the front blocking frame 3, thereby ensuring that the entire front blocking frame 3 can be extended and retracted forward, playing a limiting buffer effect and increasing the safety of the unmanned boat during recovery.

[0035] In actual use, when the unmanned boat enters the recovery device, the speed may be out of control, or there may be safety hazards in the unmanned boat and it may be out of control. The head of the unmanned boat will directly hit the buffer pad for a buffering. Then, the first connecting section 30 and the second connecting section 31 on the front blocking frame 3 will pull the slider 21 to slide through the pulling member 23, and the elastic member 22 connected to the slider 21 will be directly stretched by the force, thereby reducing the impact force of the unmanned boat. Moreover, after the slider 21 slides to a point, it can further contact the rubber pad 25 on the limit block 24, thereby further achieving the buffering effect.

[0036] It should be noted that the position setting of the limit block 24 is only an approximate position and can be set according to actual needs, which is not limited in this case.

[0037] Furthermore, the elastic member 22 is a spring.

[0038] Furthermore, the pulling member 23 is made of spandex or iron rope, etc., and the specific implementation can be selected according to actual needs.

[0039] Among them, one end of the pulling member 23 is connected to the first connecting section 30 on the front blocking frame 3, so that when the unmanned boat collides with the recovery device, the front blocking frame 3 and the upper connecting component 2 cooperate with each other, thereby reducing the impact force of the unmanned boat.

[0040] It also includes a positioning mechanism 9, which includes a folding member 90. The folding member 90 further includes a fixed block 901 arranged on the enclosure frame 1, an axle 902 arranged between the fixed blocks 901, a torsion coil spring 903 wound around both ends of the axle 902, and a positioning plate 904 connected to one end of the torsion coil spring 903; a positioning flap 91 is provided on the outer wall of the axle 902, and connecting rods 92 are provided at the upper and lower ends of the positioning flap 91, and a roller 93 is rotatably provided between the two connecting rods 92.

[0041] Among them, when the unmanned boat enters the recovery device, the head of the unmanned boat first contacts the positioning flap 91, and as the unmanned boat enters, one end of the positioning flap 91 moves outward through the shaft 902, and the roller 93 on the connecting rod 92 contacts the outer wall of the unmanned boat, so that the unmanned boat can be limited and moved by the roller 93. When the unmanned boat completely enters the recovery device, the positioning flap 91 will be reset through the torsion spring 903 on the shaft 902, thereby contacting the tail of the unmanned boat, which not only plays a limiting effect, but also ensures that the unmanned boat will not tilt when entering the recovery device, thereby achieving the effect of positioning recovery and preventing scratches.

[0042] Furthermore, the structural coordination of the torsion coil spring 903 , the shaft 902 and the positioning plate 904 is conventional, and will not be described in detail here.

[0043] The connecting belt 4 is made of spandex or a composite elastic fiber. In one embodiment, the connecting belt 4 is preferably made of spandex. This is because spandex can be stretched 6 to 7 times and can quickly return to its original state. It has high elongation (500% to 700%) and high elastic recovery rate (95% to 99%), ensuring that it will not break when the recovery device is pulled. Furthermore, since the connecting belt 4 is made of spandex, it can also play a role in preventing swaying when the unmanned boat is recovered, preventing strong shaking during recovery of the recovery device, further improving recovery safety.

[0044] Reference Figure 1 As shown, the inner edge of the enclosure frame 1 is symmetrically provided with a receiving plate for connecting to the unmanned boat, and the surface of the receiving plate is provided with anti-slip grooves, thereby increasing the friction with the bottom of the unmanned boat, improving the stability of the unmanned boat, and further improving the safety of the unmanned boat during recovery.

[0045] Reference Figure 1As shown, the front blocking frame 3 is also provided with a buffer pad for the unmanned boat. The buffer pad is made of rubber and can come into contact with the unmanned boat, thereby preventing the unmanned boat and the recovery device from being damaged due to the unmanned boat losing control or speeding too fast.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
