Description

Technical Field

[0001] This utility model relates to the field of unmanned vessel technology, specifically to an unmanned vessel launching and recovery device. Background Technology

[0002] Unmanned surface vessel (USV) deployment and recovery devices refer to equipment used for deploying, performing tasks, and recovering unmanned surface vessels on the water surface.

[0003] A Chinese patent (CN216994769U) discloses an unmanned surface vessel (USV) launching assistance device. The device includes an arched ramp, a roller assembly mounted on the ramp to assist the vessel's movement, and a pulling assembly that moves the vessel along the ramp. This invention facilitates launching or landing the vessel, avoiding the damage and safety hazards associated with manual operation. Its structure is reasonable and ingeniously designed, making it safe and labor-saving to operate without damaging the vessel or depth measuring device.

[0004] The aforementioned device is not very practical because the angle of the arched slope slide cannot be adjusted according to different conditions such as high bank slopes, deep water areas, and shallow water areas, nor can it be easily adjusted according to different sizes of boats.

[0005] In addition, the device is large in size and weight, making it difficult to carry and assemble, and it is time-consuming and labor-intensive in actual use. Therefore, it is necessary to propose an unmanned vessel launching and recovery device to solve the above problems. Summary of the Invention

[0006] The purpose of this utility model is to provide an unmanned vessel launching and recovery device, which is adaptable to different conditions such as high banks, deep water areas, and shallow water areas. It is easy to assemble and disassemble the slide and the fixed shaft, and it uses an inflatable airbag to facilitate the compression and storage of the airbag, making it easy to carry.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an unmanned vessel launching and recovery device, comprising an auxiliary device, wherein the auxiliary device comprises a first fixed shaft and a second fixed shaft, both the first fixed shaft and the second fixed shaft having internal grooves, both of the two grooves having two symmetrically distributed sliders slidably connected inside, the other ends of the four sliders being hinged to support blocks via hinge seats, and the four support blocks being fixedly connected to each other in pairs via sliding tracks;

[0008] Airbags are provided at both ends of the second fixed shaft, and airbag inflation nozzles are connected to the upper ends of both airbags.

[0009] The outer walls of the first and second fixed shafts are provided with multiple evenly distributed limiting holes, and the outer walls of the four sliders are provided with through holes that are adapted to the limiting holes. The limiting holes are detachably connected to one of the sliders by a pin.

[0010] To facilitate support of the bottom of the hull, the two sliding tracks, as a preferred embodiment of the unmanned vessel launching and recovery device of this utility model, are both inclined inward on opposite sides.

[0011] In order to increase the support area of ​​the second fixed shaft on the water surface and increase stability, the size of the first fixed shaft is preferably smaller than the size of the second fixed shaft in the unmanned vessel launching and recovery device of this utility model.

[0012] To facilitate limiting the two ends of the pin, in a preferred embodiment of the unmanned vessel launching and recovery device of this utility model, both the front and rear ends of the pin are threaded with limit blocks.

[0013] To improve the sealing of the airbag inflation nozzle, as a preferred embodiment of the unmanned vessel launching and recovery device of this utility model, the upper end of the airbag inflation nozzle is equipped with a sealing cap.

[0014] To increase the stability of the slider inside the chute, as a preferred embodiment of the unmanned vessel launching and recovery device of this invention, the outer wall of the slider abuts against the inner wall of the chute.

[0015] To facilitate the limiting of the first fixed shaft, as a preferred embodiment of the unmanned vessel launching and recovery device of this utility model, the lower end of the first fixed shaft is fixedly connected with two symmetrically distributed inserts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, a slider connected to two slide rails is fixed inside the corresponding slide groove by a pin, and two airbags are inflated to complete the assembly of the auxiliary device.

[0018] The first fixed shaft is placed on the shore, and the second fixed shaft is placed on the water surface. The slider and the support block are hinged to adapt to the shore slope of different heights. When launching, the unmanned boat is placed on the upper part of the slide and pulled by the rope to move the unmanned boat along the slide to the water surface to complete the launch. When recovering, the unmanned boat is controlled to dock at the lower part of the two slides and pulled by the rope to move the unmanned boat along the slide to the shore to complete the recovery.

[0019] When the auxiliary device is not in use or its position needs to be changed, the entire auxiliary device is moved to the shore, the two airbags are deflated, compressed and stored, and multiple sliders are removed from the slide groove by disassembling the pins, so that the two slides are separated from the first and second fixed shafts. This allows it to adapt to different conditions such as high bank slopes, deep water areas, and shallow water areas, and facilitates the assembly and disassembly of the slides and fixed shafts. With the help of inflatable airbags, the airbags can be easily compressed and stored, making it easy to carry. Attached Figure Description

[0024] Please see Figures 1 to 3 An unmanned vessel launching and recovery device includes an auxiliary device, which includes a first fixed shaft 1 and a second fixed shaft 2. The first fixed shaft 1 and the second fixed shaft 2 are both provided with a sliding groove 3. Two symmetrically distributed sliders 4 are slidably connected inside the two sliding grooves 3. The other ends of the four sliders 4 are all hinged to support blocks 6 through hinge seats. The four support blocks 6 are all fixedly connected to each other in pairs with sliding tracks 5.

[0025] Airbags 7 are provided at both ends of the second fixed shaft 2, and airbag inflation nozzles 8 are connected to the upper ends of both airbags 7.

[0026] The outer walls of the first fixed shaft 1 and the second fixed shaft 2 are provided with multiple evenly distributed limiting holes 11. The outer walls of the four sliders 4 are provided with through holes 12 that are adapted to the limiting holes 11. The limiting holes 11 and one of the sliders 4 are detachably connected by a pin 10.

[0027] In this embodiment: during use, the slider 4 connected to the two slide rails 5 is fixed inside the corresponding slide groove 3 by the pin 10, and the assembled shape is as follows. Figure 1 As shown (in a "well" shape), the two airbags 7 are inflated, the first fixed shaft 1 is placed on the shore, and the slider 4 is hinged to the support block 6 to adapt to different slope heights. The second fixed shaft 2 is placed on the water surface. The buoyancy of the two airbags 7 in the water can support the two slides 5, ensuring that the end of the slide 5 remains on the water surface and that the slide 5 does not tilt. When launching, the unmanned boat is placed on the upper part of the slide 5 and pulled by the rope to move the unmanned boat along the slide 5 to the water surface to complete the launch. When recovering, the unmanned boat is controlled to dock at the lower part of the two slides 5 and pulled by the rope to move the unmanned boat along the slide to the shore to complete the recovery.

[0028] When the auxiliary device is not in use or its position needs to be changed, the entire auxiliary device is moved to the shore, the two airbags 7 are emptied, compressed and stored, and the multiple sliders 4 are removed from the slide groove 3 by disassembling the pin 10, so that the two slides 5 are separated from the first fixed shaft 1 and the second fixed shaft 2, thereby making it easier to store the entire auxiliary device and reducing the space occupied.

[0029] As a technical optimization of this utility model, the opposite sides of the two slides 5 are both inclined inward.

[0030] In this embodiment, the two slides 5 are inclined inward on opposite sides, which facilitates the support of the bottom of the unmanned boat.

[0031] As a technical optimization of this utility model, the size of the first fixed shaft 1 is smaller than the size of the second fixed shaft 2.

[0032] In this embodiment, the size of the first fixed shaft 1 is smaller than the size of the second fixed shaft 2, which can increase the support area of ​​the second fixed shaft 2 on the water surface and increase stability.

[0033] As a technical optimization of this utility model, both the front and rear ends of the pin 10 are threadedly connected to the limit block 9.

[0034] In this embodiment, the two ends of the pin 10 can be conveniently limited by the limiting block 9.

[0035] As a technical optimization of this utility model, a sealing cap is installed on the upper end of the airbag inflation nozzle 8.

[0036] In this embodiment, the sealing performance of the airbag inflation nozzle 8 can be increased by using a sealing cap.

[0037] As a technical optimization of this utility model, the outer wall of the slider 4 abuts against the inner wall of the groove 3.

[0038] In this embodiment, the outer wall of the slider 4 abuts against the inner wall of the groove 3, which can increase the stability of the slider 4 inside the groove 3.

[0039] As a technical optimization of this utility model, the lower end of the first fixed shaft 1 is fixedly connected to two symmetrically distributed inserts.

[0040] In this embodiment, the first fixed shaft 1 can be conveniently limited by inserting the insertion post into the ground on the shore.

[0041] Working principle: In use, the slider 4 connected to the two slide rails 5 is first fixed inside the corresponding slide groove 3 by the pin 10. The installation position of the slider 4 inside the slide groove 3 can be easily adjusted by the multiple limiting holes 11, thereby adjusting the distance between the two slide rails 5. This allows it to adapt to boats of different sizes, making it widely applicable. The assembled shape is as follows: Figure 1 As shown (in a "well" shape), inflate the two airbags 7 (different volumes of gas can be filled as needed), place the first fixed shaft 1 on the shore through the insert post, and hinge the slider 4 to the support block 6. The two slides 5 can be finely adjusted according to the dynamic movement of the airbags 7 on the water surface to adapt to different bank slopes. Place the second fixed shaft 2 on the water surface. The buoyancy of the two airbags 7 in the water can support the two slides 5, ensuring that the ends of the slides 5 remain on the water surface and that the slides 5 do not tilt. When launching, place the unmanned boat on the slides 5 (with the bottom of the unmanned boat placed between the inclined surfaces of the two slides 5). At this time, the support block 6 tilts forward to its limit position around the hinge due to the weight of the slides 5 and the unmanned boat. The unmanned boat is pulled along the slides 5 to the water surface by the rope, completing the launch. When recovering, maneuver the unmanned boat to dock at the bottom of the two slides 5 and pull it along the slides to the shore by the rope, completing the recovery.

[0042] When the auxiliary device is not in use or its position needs to be changed, the entire auxiliary device is moved to the shore, the two airbags 7 are emptied, compressed and stored, and the multiple sliders 4 are removed from the slide groove 3 by disassembling the pin 10, so that the two slides 5 are separated from the first fixed shaft 1 and the second fixed shaft 2, thereby making it easier to store the entire auxiliary device and reducing the space occupied.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
