Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to an air-sea dual-purpose unmanned aerial vehicle with an anchor chain structure. Background Art

[0002] Anchor chain refers to a special chain that connects the anchor and the drone and transmits the anchor's grip. The anchor chain structure can stabilize the fuselage in a fixed area and prevent it from floating around with the waves. With the gradual maturity of drone research and development technology, the manufacturing cost has been greatly reduced. Drones have been widely used in various fields. In addition to military use, they are also used in agricultural plant protection, power inspections, geological exploration, environmental monitoring, forest fire prevention, and aerial photography for film and television. In addition, drones have great application prospects in water. They can be used for underwater detection and underwater rescue. The air-sea dual-use drone can achieve fast and effective large-scale underwater detection by switching its underwater route to the air. The conversion of drones in the air and in the sea can effectively increase the practicality of detection. The following problems exist in the existing technology:

[0003] The current anchor chain structure is integrated with the air-sea dual-purpose UAV, which makes it impossible to disassemble and replace them. At the same time, since the tail wing of the air-sea dual-purpose UAV with the anchor chain structure is not provided with a telescopic structure, the tail wing is easily broken during transportation.

[0007] A fixing plate is fixedly connected inside the anchor chain device, a slot is provided on the upper surface of the fixing plate, a slide slot is provided inside the drone body, a clamping rod is slidably connected inside the slide slot, and the lower end of the clamping rod is clamped with the temporal part of the slot.

[0011] By adopting the above technical solution, the anchor chain device can be installed and disassembled by the method through the mutual cooperation of the screws, the push rod and the reinforcing seat.

[0012] A further improvement of the technical solution of the present invention is that: the internal movably connected to the reinforcing seat is a limit rod, the upper end of the limit rod is fixedly connected to the limit block, the lower end of the limit rod is inserted into the interior of the push rod, the lower end of the limit rod extends to the outside of the push rod, and a nut is provided on the surface of the limit rod, and the upper surface of the nut overlaps the lower surface of the push rod.

[0013] By adopting the above technical solution, the fixing effect of the push rod is enhanced through the mutual cooperation of the limiting rod, the limiting block and the nut.

[0017] By adopting the above technical solution, the limit spring and the protrusion cooperate with each other, thereby facilitating the effect of fixing and clamping the tail wing.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with embodiments:

[0027] Example 1

[0028] like Figure 1-4 As shown, the present invention provides an air-sea dual-purpose UAV with an anchor chain structure, comprising a UAV body 1, a bottom of the UAV body 1 is fixedly connected to an anchor chain device 2, one end of the UAV body 1 is fixedly connected to a sleeve 3, one end of the sleeve 3 is provided with a tail 4, the interior of the anchor chain device 2 is fixedly connected to a fixing plate 21, the upper surface of the fixing plate 21 is provided with a card slot 22, the interior of the UAV body 1 is provided with a slide groove 11, the interior of the slide groove 11 is slidably connected to a card rod 12, the lower end of the card rod 12 is carded with the temporal part of the card slot 22, one side of the card rod 12 is fixedly connected to a spring 13, one end of the spring 13 is fixedly connected to a spring plate 14, one side of the spring plate 14 is fixedly connected to the inside of the drone body 1, the lower end of the spring plate 14 extends to the inside of the anchor chain device 2, the inside of the spring plate 14 is movably connected with a screw 17, the surface of the screw 17 is movably connected to the inside of the anchor chain device 2, the inside of the spring plate 14 is slidably connected with a push rod 15, one end of the push rod 15 extends to the outside of the drone body 1, the other end of the push rod 15 is fixedly connected to one side of the clamping rod 12, the surface of the push rod 15 is movably connected to the inside of the drone body 1, and the upper surface of the push rod 15 is provided with a reinforcement seat 16, and one side of the reinforcement seat 16 is fixedly connected to one side of the drone body 1.

[0029] In this embodiment, when it is needed, the air-sea dual-purpose UAV is controlled by a remote controller, and flies to the ocean. Then, the anchor chain device 2 is opened by the setting of the remote controller so that the internal anchor chain is dropped into the sea, so that the fuselage is stabilized in a fixed area and does not float around with the waves. When the anchor chain device 2 needs to be replaced according to the actual situation of the ocean, the screw 17 is taken out with a tool and the push rod 15 is loosened through the reinforcing seat 16. At the same time, the push rods 15 on both sides are pushed and the spring 13 is squeezed, so that the clamping rod 12 is moved closer to the middle inside the slide groove 11 and rubbed away from the position of the clamping groove 22, and then the anchor chain device 2 is taken down for disassembly, thereby facilitating the replacement of the anchor chain device 2.

[0030] Example 2

[0031] like Figure 1-4 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the internal movable connection of the reinforcing seat 16 is connected to the limiting rod 161, the upper end of the limiting rod 161 is fixedly connected to the limiting block 162, the lower end of the limiting rod 161 is inserted into the interior of the push rod 15, and the lower end of the limiting rod 161 extends to the outside of the push rod 15, and the surface of the limiting rod 161 is provided with a nut 163, and the upper surface of the nut 163 overlaps with the lower surface of the push rod 15.

[0032] In this embodiment, when the push rod 15 needs to be loosened before disassembly, the lower end of the limit rod 161 is provided with a thread, and the nut 163 is rotated in the opposite direction and removed, and then the limit rod 161 is moved upward and pulled out by holding the limit block 162, thereby loosening the push rod 15.

[0033] Example 3

[0034] like Figure 1-4 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the interior of the sleeve 3 is fixedly connected with a slide rod 31, one end of the slide rod 31 is fixedly connected with a buffer spring 32, one end of the buffer spring 32 is overlapped with a connecting block 33, one end of the connecting block 33 is fixedly connected with a plate 34, one end of the plate 34 is fixedly connected to one end of the tail wing 4, the surface of the tail wing 4 is movably connected to the interior of the sleeve 3, the surface of the plate 34 is fixedly connected to a limiting spring 35, one end of the limiting spring 35 is fixedly connected with a protrusion 36, one end of the protrusion 36 extends to the outside of the sleeve 3, and the surface of the protrusion 36 is movably connected to the interior of the sleeve 3.

[0035] In this embodiment, when transportation is required, the protrusions 36 on both sides are pressed and the limit spring 35 is squeezed, so that the limit spring 35 and the protrusion 36 are retracted inside, and then the tail wing 4 is pushed to make the connecting block 33 move to the right on the surface of the sliding rod 31 and separate from the buffer spring 32, so that the tail wing 4 is retracted inside the sleeve 3. When it is needed to use, the tail wing 4 is pulled hard to make the connecting block 33 move to the left on the surface of the sliding rod 31 and squeeze the buffer spring 32. At the same time, due to the elastic effect of the limit spring 35, the protrusion 36 is pushed to move and extend out of the sleeve 3. At this time, the limit spring 35 changes from a retracted state to a raised state, thereby clamping and fixing the tail wing 4.

[0036] Let’s talk about the working principle of this air-sea dual-purpose UAV with an anchor chain structure in detail.

[0037] like Figure 1-4 As shown, when it is needed, the air-sea dual-purpose UAV is controlled by a remote controller and flies to the ocean. Then, the anchor chain device 2 is opened by the setting of the remote controller so that the internal anchor chain is dropped into the sea, thereby stabilizing the fuselage in a fixed area and not floating around with the waves. When the anchor chain device 2 needs to be replaced, the screw 17 is taken out and the push rod 15 is loosened through the reinforcing seat 16. Due to the cooperation of the push rod 15 and the spring 13, the clamping rod 12 moves inside the slide groove 11 and is rubbed away from the position of the clamping groove 22, thereby being disassembled. When the UAV is transported, the protrusions 36 on both sides are pressed and the limit spring 35 is squeezed, so that the limit spring 35 and the protrusion 36 are retracted inside, and then the tail 4 is pushed so that the connecting block 33 moves to the right on the surface of the slide rod 31 and is separated from the buffer spring 32, thereby realizing the contraction of the tail 4 inside the sleeve 3.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
