DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] See also Figures 1 to 5 As shown, the utility model provides a large unmanned helicopter deck storage and transfer system, including a storage box 1 and an omnidirectional AGV transfer platform 2, wherein the storage box 1 is used to store a large-load unmanned helicopter 3; a storage box retractable door 103 is provided at the rear end of the storage box 1, and when the storage box retractable door 103 is opened downward, a transition springboard is formed for the omnidirectional AGV transfer platform 2 to enter and exit the storage box 1; the omnidirectional AGV transfer platform 2 includes an omnidirectional AGV trolley 201 and a lifting mechanism arranged on the omnidirectional AGV trolley 201; when the omnidirectional AGV trolley 201 enters under the large-load unmanned helicopter 3, the lifting mechanism is used to lift or lower the large-load unmanned helicopter 3, and the omnidirectional AGV trolley 201 is used to carry and transfer the large-load unmanned helicopter 3.

[0027] See also Figure 5 As shown, in the embodiment of the present invention, the storage box 1 is set on the ship deck 5, which simplifies the daily storage and maintenance operations of the large-load unmanned helicopter 3 on the ship deck 5. The size of the storage box 1 is 40 feet to provide space for accommodating the large-load unmanned helicopter 3.

[0028] See also Figure 3 As shown, in the embodiment of the present invention, the storage box 1 includes a storage box body 101 with an open rear end, the lower end of the storage box retractable door 103 is hinged to the rear end bottom of the storage box body 101, and the upper end can be opened and closed; the inner rear end of the storage box body 101 is provided with a door opening drive mechanism for opening and closing the storage box retractable door 103.

[0029] Specifically, the door-opening mechanism includes two hydraulic door-retracting push-pull rods 102 symmetrically positioned on either side of the rear end of the storage box 101. The rear ends of these hydraulic door-retracting push-pull rods 102 are hinged to the storage box 101, and their output ends are hinged to the storage box retractable door 103. The two multi-stage hydraulic door-retracting push-pull rods 2 enable the retraction and extension of the storage box retractable door 103, which can be positioned at any angle. Their primary purpose is to serve as a transitional springboard during the transfer of a large-load unmanned helicopter 3, providing a ramp at a suitable angle for the omnidirectional AGV transfer platform 2.

[0030] Furthermore, a fixing structure for securing the high-load unmanned helicopter 3 is provided within the storage box 101. In this embodiment, the fixing structure comprises a plurality of sliding tripod fixing clamps 104. Each sliding tripod fixing clamp 104 is provided with a slot for positioning the lifting support frame 4 of the high-load unmanned helicopter 3. The sliding tripod fixing clamps 104 are secured to the storage box 101 via connectors. The sliding tripod fixing clamps 104 can be slidably adjusted to flexibly adjust the fixing according to the size of the lifting support frame 4 of the high-load unmanned helicopter 3.

[0031] See also Figure 4 As shown, in an embodiment of the present invention, four Mecanum wheels 202 are provided at the bottom of the omnidirectional AGV trolley 201. The lifting mechanism is a commercially available product purchased from Hanton Transmission Equipment (Shandong) Co., Ltd., model DFL025. The lifting mechanism includes a high-torque motor 205, a lateral transmission shaft 204, a transverse transmission shaft 206 and four bevel gear elevators 203. The high-torque motor 205 is connected to two of the bevel gear elevators 203 through two transverse transmission shafts 206. These two bevel gear elevators 203 are then connected to the other two bevel gear elevators 203 through the lateral transmission shafts 204, thereby forming a lifting platform. By controlling the forward and reverse rotation of the high-torque motor 205, the lifting amplitude of the lifting mechanism is controlled, so that the omnidirectional AGV transfer platform can "carry" and "release" the large-load unmanned helicopter 3 and complete the transfer task.

[0032] Specifically, the lifting mechanism can also adopt four independently driven spiral elevators, or any lifting mechanism that can realize the lifting function, so as to make fine adjustments according to the deck slope to ensure that the large-load unmanned helicopter 3 remains horizontal on any slope during the transportation process.

[0033] The omnidirectional AGV trolley 201 serves as the main transport mechanism, and is designed with a freely adjustable lifting mechanism and control system. In addition, the omnidirectional AGV trolley 201 uses four Mecanum wheels 202 to achieve omnidirectional movement without blind spots, ensuring that the unmanned helicopter 3 carrying a large payload can be fine-tuned in all directions within the narrow space of the 40-foot storage box 1, and is convenient for docking and locking with the sliding tripod fixing clamp 104 inside the storage box 1.

[0034] The lifting mechanism can carry the heavy-load unmanned helicopter 3 by supporting two lifting supports 4 connected to the legs of the heavy-load unmanned helicopter 3. The lifting support has a simple structure and is convenient for docking and installation with most types of landing gear.

[0035] The utility model provides a large-scale unmanned helicopter deck storage and transfer system with a standard structure and convenient installation. It can be used by docking and installing it with small, medium or large cargo ships according to the installation method of standard container size.

[0036] Figure 5 This is the workflow diagram for storage and transshipment on deck in the utility model. The detailed workflow is as follows;

[0037] (1) Deployment process of large unmanned helicopter deck storage and transfer system on ship deck:

[0038] Step 1: Open the storage box door 103 and loosen the sliding bracket fixing clamp 104;

[0039] Step 2: The omnidirectional AGV transfer platform 2 lifts the large-load unmanned helicopter 3 and transfers it to the take-off location;

[0040] Step 3: After the large-load unmanned helicopter 3 arrives at the take-off point, the omnidirectional AGV transfer platform 2 separates from the large-load unmanned helicopter 3;

[0041] Step 4: After the omnidirectional AGV transfer platform 2 separates from the large-load unmanned helicopter 3, it returns to the standby area to wait for the drone to be recovered;

[0042] Step 5: The large-load unmanned helicopter 3 takes off to perform the mission.

[0043] (2) Large unmanned helicopter deck storage and transfer system ship deck recovery process:

[0044] Step 1: The large-load unmanned helicopter 3 completes its mission and returns to land on the ship deck 5;

[0045] Step 2: The omnidirectional AGV transfer platform 2 lifts the large-load unmanned helicopter 3 and transfers it to the door of the storage box;

[0046] Step 3: The omnidirectional AGV transfer platform 2 transfers the large-load unmanned helicopter 3 into the storage box 1 and aligns it with the sliding tripod fixing clamp 104;

[0047] Step 4: After the omnidirectional AGV transfer platform 2 is aligned with the sliding foot frame fixing clamp 104, the lifting mechanism is retracted and enters standby mode;

[0048] Step 5: After the unmanned helicopter's tripod is locked, it enters standby mode and waits for the next round of mission dispatch.

[0049] The above workflow can realize fully autonomous transfer or semi-autonomous transfer with humans in the control loop, thus providing an efficient transfer method and means for the daily operation and maintenance, deployment and recovery of unmanned helicopters on ship decks.

[0050] The utility model provides a large unmanned helicopter deck storage and transfer system, which can realize fully autonomous transfer and semi-autonomous transfer with people in the control loop, thereby greatly improving the simplicity of daily storage and maintenance operations of large unmanned helicopters on the ship deck, reducing maintenance personnel, and allowing large unmanned helicopters to be deployed and recovered on the ship deck conveniently and quickly.
