Description

Technical Field

[0001] The present invention relates to the technical field of material delivery equipment for ground effect vehicles, and in particular to a high-efficiency automated material delivery platform based on a wing-in-ground-effect vehicle and an operation method thereof. Background Art

[0002] A wing-in-ground-effect vehicle is a vessel designed and manufactured using the principle of ground effect. It combines the advantages of a ship's large load capacity and an airplane's high speed. Compared with traditional air and sea transport, it usually glides and takes off on the water surface. It does not require the construction of large-scale bases and facilities, and can easily fly close to the water surface and the ground. It can also take off and land in special environments such as shallows and swamps where traditional transportation tools are difficult to use.

[0003] Currently, research on maritime material delivery primarily focuses on conventional transport vessels, while research on WIG craft for maritime material delivery is insufficient. Unlike conventional ships, WIG craft combine the high-speed characteristics of aircraft with the high-load capacity of ships. They are specialized vehicles characterized by high speed, high payload, strong environmental adaptability, excellent military concealment, and safety. Furthermore, WIG craft are susceptible to varying wind and wave levels at sea, increasing the difficulty of material delivery. Existing WIG craft rely primarily on simple manual handling, resulting in low material loading and unloading efficiency and a lack of rapid and accurate delivery capabilities suitable for multiple scenarios. Therefore, innovative research on WIG craft material delivery platforms and methods is necessary to further expand maritime transport support capabilities. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a high-efficiency automated material delivery platform and operation method based on the ground effect wing vehicle, so that the ground effect wing vehicle can deliver materials efficiently, quickly and safely at sea.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] A high-efficiency automated material delivery platform based on a ground effect wing vehicle comprises a fuselage, a cargo hold body is provided inside the fuselage, a cargo hold delivery port is provided at the front end of the cargo hold body, and a fixed deck module, a movable deck module and a safety assurance module are arranged inside the cargo hold body;

[0007] The fixed deck module includes a fixed deck installed at the rear of the cargo hold body, an electric roller conveyor installed on the upper surface of the fixed deck, and the electric roller conveyor transports materials. The fixed decks on both sides of the electric roller conveyor are provided with spaced transverse hanging points, and the fixed decks outside the transverse hanging points are provided with spaced longitudinal hanging points.

[0008] The movable deck module includes a movable deck hinged to the fixed deck, a pull rod mechanism connection point and a main actuator connection point are provided on the upper surface of the movable deck, a roller conveying mechanism is installed on the upper surface of the movable deck, and the roller conveying mechanism is connected to the electric roller conveying device;

[0009] The auxiliary actuator, No. 1 connecting rod and main actuator are installed on the top of the cargo hold. The push-pull rod of the auxiliary actuator is connected to the middle symmetrical position of the No. 1 connecting rod. The No. 1 connecting rod is hinged to the No. 2 connecting rod. The No. 3 connecting rod is installed between the connection point of the No. 2 connecting rod and the pull rod mechanism. The push-pull rod of the main actuator is connected to the connection point of the main actuator. The main actuator controls the raising and lowering of the movable deck.

[0010] The safety assurance module includes a safety rope box arranged at the cargo hold loading port, which is used to retract and release the safety rope.

[0011] Its further technical solution is:

[0012] The electric roller conveying device is composed of rows of rollers parallel to each other. Each roller can rotate freely, and all rollers can be controlled by the motor to rotate simultaneously in the same direction.

[0013] The longitudinal hanging points and the transverse hanging points both adopt a sunken structure.

[0014] The upper surface of the movable deck is provided with an anti-slip mat.

[0015] The roller conveying mechanism is composed of rows of rollers parallel to each other, each roller rotates freely, and the roller conveying mechanism is installed on the central symmetry line position of the upper surface of the movable deck. The direction of the roller conveying mechanism is parallel to the forward direction of the ground effect vehicle.

[0016] The roller conveying mechanism slides the materials into the sea surface.

[0017] The No. 1 connecting rod has a triangular structure.

[0018] An operating method for an efficient automated material delivery platform based on a wing-in-ground-effect vehicle includes the following operating procedures:

[0019] After the materials are stacked on the electric roller conveyor in the cargo hold of the WIG craft, the staff will use ropes to tie the stacked materials and tie the ends of the ropes to the longitudinal or transverse hanging points;

[0020] Then, the push-pull rod of the main actuator is controlled to retract, and the push-pull rod of the auxiliary actuator is controlled to extend at the same time, so that the movable deck is slowly lifted as a whole. As the movable deck is lifted, the No. 1 connecting rod, the No. 2 connecting rod, and the No. 3 connecting rod begin to rotate relative to each other and fold;

[0021] When the movable deck is lifted to the designated position, the push-pull rods controlling the main actuator stop retracting and remain in the current position. At the same time, the auxiliary actuator is released from control. After the release of control, the push-pull rods of the auxiliary actuator can be freely extended and retracted at any time by external forces, entering the folded state. The cargo hold launch port is then closed, and the WIG craft begins to glide and take off on the sea surface.

[0022] After the WIG vehicle arrives at the target sea area with the supplies, it lands on the sea surface, completes the supply delivery while gliding on the sea surface, and then directly takes off and leaves the target sea area, achieving the completion of supply delivery without stopping the WIG vehicle's engine. It can also be driven to fly close to the sea surface and complete the supply delivery during the flight.

[0023] When preparing to drop supplies, the cargo hold drop port is opened first, and then the push-pull rod of the main actuator is controlled to extend. At this time, the push-pull rod of the auxiliary actuator is still in a free extension and retraction state. Under the thrust of the push-pull rod of the main actuator, the movable deck begins to fall. When the movable deck falls to the designated position, the main actuator stops and maintains the current position. At this time, the No. 1 connecting rod, No. 2 connecting rod, and No. 3 connecting rod are straightened and maintain this stable state. Then the staff starts to drop supplies.

[0024] First, untie the ropes that bind the materials.

[0025] Then the electric roller conveyor is started to move the materials piled on it rapidly toward the stern of the WIG craft. The materials are transported to the movable deck at a certain speed. At this time, the materials are ejected from the cargo hold by their own weight, inertia speed and each roller on the roller conveyor mechanism.

[0026] Finally, the main actuator and auxiliary actuator are controlled to raise the movable deck and close the cargo hold launch port;

[0027] The material delivery is completed.

[0028] The beneficial effects of the present invention are as follows:

[0029] The present invention has a compact and reasonable structure and is easy to operate. Through the mutual cooperation between modules such as the fixed deck module, the movable deck module and the safety assurance module, the ground effect wing-in-ground-effect vehicle can realize the efficient, rapid and safe delivery of materials at sea, improve the material transportation efficiency of the ground effect wing-in-ground-effect vehicle, further develop the application field of material transportation of the ground effect wing-in-ground-effect vehicle, and better serve the actual needs of my country's long-distance transportation.

[0030] When the present invention is working, materials are piled above the electric roller conveyor device in the fixed deck module, and ropes or rope nets are used to bind and fix the materials, and the ends of the ropes are tied to longitudinal hanging points and transverse hanging points. When the ground effect wing ship flies to the target delivery area, the ropes or rope nets used to bind and fix the materials are untied, the cargo hold delivery port is opened, the movable deck is lowered, and the electric roller conveyor device is started to quickly transport the materials toward the cargo hold delivery port. When the materials are transported to the movable deck, the inertial speed and self-weight of the materials at this time and the roller conveyor device on the movable deck are utilized to quickly and smoothly throw them out of the cargo hold. This delivery process can be carried out when the ground effect wing ship is flying close to the water surface or the ground, and can also be carried out when the ground effect wing ship is gliding on the water surface. The whole process enables the ground effect wing ship to complete the delivery of materials without stopping the engine.

[0031] The present invention can be used as an efficient material delivery platform for ground effect wing vehicles (ground effect vehicles), and is suitable for scenarios such as military logistics, disaster relief, and long-sea transportation. BRIEF DESCRIPTION OF THE DRAWINGS

The direction of the roller conveying mechanism 10 is parallel to the forward direction of the ground effect vehicle.

[0048] The roller conveying mechanism 10 slides the materials 15 into the sea surface.

[0049] The No. 1 connecting rod 4 has a triangular structure.

[0050] The specific structure and functions of the high-efficiency automated material delivery platform based on the ground effect wing vehicle described in the present invention are as follows:

[0051] It mainly includes fixed deck module, movable deck module and safety assurance module.

[0052] The fixed deck module includes a fixed deck 13 , an electric roller conveyor 12 , a longitudinal hanging point 19 , and a transverse hanging point 20 .

[0053] Among them, the fixed deck 13 is installed in the cargo hold at the rear of the ground effect vehicle, and the electric roller conveyor 12, the longitudinal hanging point 19, and the transverse hanging point 20 are arranged on the upper surface of the fixed deck 13. The fixed deck 13 is a stacking platform for items in the entire cargo hold.

[0054] Among them, the electric roller conveyor 12 is composed of rows of rollers parallel to each other. Each roller can rotate freely, and all rollers can be controlled by an electric motor to rotate in the same direction at the same time. It is installed on the central symmetry line of the upper surface of the fixed deck 13, and its direction is parallel to the forward direction of the ground effect vehicle. Its function is to transport the materials 15 to the roller conveyor mechanism 10 on the upper surface of the movable deck 9, so as to achieve better connection.

[0055] The longitudinal hanging points 19 and the transverse hanging points 20 on the upper surface of the fixed deck 13 adopt a sunken design, and each hanging point does not exceed the upper surface of the fixed deck 13. Such a design does not affect the flatness of the fixed deck 13 and facilitates the stacking of materials 15.

[0056] The movable deck module includes a movable deck 9 , a roller conveying mechanism 10 , a pull rod mechanism, and a main actuator 7 .

[0057] Among them, the movable deck 9 is hinged to the tail end of the fixed deck 13, and at the connection between the movable deck 9 and the fixed deck 13, the movable deck 9 can rotate relative to each other, that is, the movable deck 9 can rotate around the fixed deck 13, and a pull rod mechanism connection point 17 and a main actuator cylinder connection point 18 are provided on the upper surface of the movable deck 9; the roller conveying mechanism 10 is also composed of rows of rollers parallel to each other, each roller can only rotate freely, and there is no motor to provide rotational power. It is installed on the central symmetry line position of the upper surface of the movable deck 9, and its direction is parallel to the forward direction of the ground effect vehicle. Its function is to slide the materials 15 transported by the electric roller conveying device 12 smoothly into the water by relying on the weight of the materials 15 themselves and the rotation of each roller in the roller conveying device.

[0058] The pull rod mechanism consists of three connecting rods and an auxiliary actuator 3. One end of the No. 1 connecting rod 4 is installed on the upper cabin roof 11. The push-pull rod of the auxiliary actuator 3 is connected to the middle symmetrical position of the No. 1 connecting rod 4. One end of the No. 3 connecting rod 6 is connected to the pull rod mechanism connection point 17 on the movable deck 9. The function of the entire pull rod mechanism is to ensure that the movable deck 9 can always be stable when it is falling, and to ensure that the materials 15 are normally delivered.

[0059] The main actuator 7 is a power device that controls the raising and lowering of the movable deck 9. Its push-pull rod is connected to the main actuator connection point 18 on the movable deck 9. The other end of the main actuator 7 is installed on the upper cabin roof 11.

[0060] The safety protection module includes a safety rope installed in a safety rope box 8 and an anti-slip mat 16. The safety rope box 8 is installed on the left and right side walls of the inner cabin near the cargo hold launch port 2. The safety rope can be freely retracted and released. When the safety rope is fully released, the safety rope will be tightened to ensure the safety of the staff while ensuring their flexibility in working on the cargo hold deck; the anti-slip mat 16 is laid on the upper surface of the movable deck 9 to prevent people from slipping into the water.

[0061] In actual work process:

[0062] After the materials 15 are stacked on the electric roller conveyor 12 in the cargo hold of the WIG craft, the staff will tie and secure the stacked materials 15 with ropes and tie the ends of the ropes to the longitudinal hanging points 19 or the transverse hanging points 20 to prevent the materials 15 from shaking during the flight of the WIG craft. Then, by controlling the push-pull rod of the main actuator 7 to retract and simultaneously controlling the push-pull rod of the auxiliary actuator 3 to extend, the movable deck 9 as a whole begins to slowly rotate and rise around the connecting axis. As the movable deck 9 rises, the No. 1 connecting rod 4, the No. 2 connecting rod 5, and the No. 3 connecting rod 6 in the pull rod mechanism begin to rotate relative to each other, and the entire pull rod mechanism begins to fold.

[0063] When the movable deck 9 is lifted to the specified position, the push-pull rod controlling the main actuator 7 stops contracting and remains in the current position. At the same time, the auxiliary actuator 3 is released from control. After the control is released, the push-pull rod of the auxiliary actuator 3 can be freely extended and contracted at any time by external force. At this time, the entire pull rod mechanism enters a folding state, and then the cargo hold launch port 2 is closed, and the ground effect craft begins to glide and take off on the sea.

[0064] After the ground effect wing craft arrives at the target sea area with the materials 15, it can land on the sea surface, complete the delivery of the materials 15 while gliding on the sea surface, and then directly glide and take off to leave the target sea area, thereby completing the delivery of the materials 15 without stopping the engine of the ground effect wing craft. The ground effect wing craft can also be driven to fly close to the sea surface and complete the delivery of the materials 15 during the flight.

[0065] When preparing to release materials 15, first open the cargo hold release port 2, then control the push-pull rod of the main actuator 7 to extend, at this time the push-pull rod of the auxiliary actuator 3 is still in a free extension and retraction state, under the thrust of the push-pull rod of the main actuator 7, the movable deck 9 begins to fall, and the connecting rods of the pull rod mechanism begin to gradually expand. When the movable deck 9 falls to the specified position, the main actuator 7 stops moving and maintains the current position, the pull rod mechanism enters the deployed state, and the No. 1 connecting rod 4, the No. 2 connecting rod 5, and the No. 3 connecting rod 6 are stretched in a straight line, so that the movable deck 9 always maintains a stable state under the joint action of the main actuator 7 and the pull rod mechanism. Then the staff starts to put the materials 15. First, the ropes that bind the materials 15 are released, and then the electric roller conveyor device is started to make the materials 15 stacked on the electric roller conveyor device 12 move rapidly toward the stern of the ground effect wing craft. The materials 15 are transported to the movable deck 9 at a certain speed. At this time, the materials 15 are thrown out of the cargo hold by relying on their own weight, inertia speed and each roller on the roller conveyor mechanism 10. Then the movable deck 9 is raised by controlling the main actuator 7 and the auxiliary actuator 3, and the cargo hold delivery port 2 is closed, thus completing the material 15 delivery process.

[0066] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.
