[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of 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.

[0057] Example 1:

[0058] See also Figure 1 - Figure 7 A fiber optic UAV complex rescue device includes a load-carrying UAV 1. A main frame 2 is installed at the bottom end of the frame portion of the load-carrying UAV 1. Both sides of the top of the main frame 2 are provided with traction components 3. A load-carrying platform 4 is installed at the bottom end of the main frame 2. Both sides of the top of the load-carrying platform 4 are provided with locking components 5. The load-carrying platform 4 carries rescue equipment or rescue supplies.

[0059] The traction assembly 3 includes two drive motors 301. The output shaft of each drive motor 301 is connected to a wire rope winding wheel 302 through a coupling. A traction wire rope 303 is wound around the wire rope winding wheel 302. A fixed pulley 304 is fixed to the edge of the main frame 2 by bolts. One end of the traction wire rope 303 is turned through the fixed pulley 304 and fixed to the two ends of the load platform 4.

[0060] The locking assembly 5 includes a micro electric telescopic rod 501, and a push block 502 is fixedly installed at the output end of the micro electric telescopic rod 501. Both ends of the push block 502 are hinged with connecting parts 503, and the other end of the connecting part 503 is hinged with a locking rod 504. The locking rod 504 is installed on the top of the main bracket 2 through a bracket, and the locking rod 504 can slide freely horizontally.

[0061] Example 2:

[0062] Based on the above embodiment 1, further description is given.

[0063] See Figure 1 、 Figure 2 Specifically, in the load-carrying drone 1:

[0064] A master control signal line 101 is plugged into one side of the frame, and the other end of the master control signal line 101 is connected to a ground control terminal, which is an operating handle, a mobile phone, or a computer.

[0065] The flight control of the load-carrying drone 1 is achieved by using one of the ground operating handles, mobile phones or computers. The master control signal line 101 is an optical fiber line, which can effectively improve the signal transmission efficiency and thus avoid signal delays and interruptions. When the signal is input on the ground, the load-carrying drone 1 and related electronic components can be executed in time, and it is also convenient to feed back the data collected by the load-carrying drone 1 and other electronic components to the ground control end in time.

[0066] An aerial signal line 102 is plugged into the other side of the rack portion. A signal splitter 103 is provided on the aerial signal line 102, and a first branch line 1031 and a second branch line 1032 are connected via the signal splitter 103.

[0067] The function of the aerial signal line 102 is to aggregate the control rights of multiple electronic components to the load-carrying UAV 1, and then cooperate with the master control signal line 101 to facilitate unified control by the ground control end.

[0068] A spring winding box 1033 is fixedly installed on the top of the main frame 2. Part of the first branch line 1031 is wound inside the spring winding box 1033, and the other end of the first branch line 1031 is plugged into the load-bearing platform 4.

[0069] The spring winding box 1033 can accommodate a certain length of the first branch line 1031. When the main frame 2 and the load-carrying platform 4 are separated, the certain length of the first branch line 1031 can be released to ensure the connection between the electronic components on the load-carrying platform 4 and the signal of the load-carrying drone 1.

[0070] The load-carrying drone 1 is also equipped with a wireless signal device to facilitate the control of the two modes of the load-carrying drone 1.

[0071] Specifically, in the load-carrying drone 1:

[0072] A high-definition camera 104 and a strong light lamp bead 105 are fixedly installed at the front end and the rear end of the frame part. The strong light lamp bead 105 is located below the high-definition camera 104.

[0073] By using the high-definition camera 104, during the flight, the road conditions in front and behind the load-carrying drone 1 can be photographed separately, so that the user can have a clearer understanding of the road conditions during the movement of the load-carrying drone 1. Combined with the lighting effect of the strong light lighting beads 105, the obstacle avoidance effect of the slot load-carrying drone 1 can be improved.

[0074] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 Specifically, a steel structure clamping plate 106 is fixedly welded to the bottom end of the frame part of the load-carrying drone 1, and a clamping slot 201 is fixed to the top end of the main frame 2. The clamping slot 201 is clamped with the steel structure clamping plate 106 when it is pushed laterally, and the clamping slot 201 and the steel structure clamping plate 106 are locked by bolts.

[0075] By clamping the positioning slot 201 and the steel structure clamping plate 106, the docking between the load-carrying drone 1 and the main frame 2 is facilitated. The positioning slot 201 and the steel structure clamping plate 106 are further locked by bolts, which can ensure the stability of the positioning slot 201 and the steel structure clamping plate 106 after docking. In addition, combined with the special structure of the positioning slot 201, when the load-carrying drone 1 drives the main frame 2 to move, it is not easy for the bolts to break due to shear force, thereby ensuring the stability and safety of the entire device during use.

[0076] Specifically, in the same traction component 3:

[0077] The driving motor 301 and the wire rope winding wheel 302 are fixed on the upper part of the main frame 2 through the bracket;

[0078] The two driving motors 301 are asynchronously controlled, and the two fixed pulleys 304 are parallel and both are arranged at an angle of 45 degrees upward.

[0079] The speed of the driving motor 301 determines the release speed of the traction wire rope 303, specifically:

[0080] When the load platform 4 needs to be docked or separated from the main frame 2, the drive motor 301 rotates in the same direction and speed, and the traction wire rope 303 pulls the load platform 4 up or down, so that the load platform 4 and the main frame 2 can be docked.

[0081] After the load-carrying platform 4 is separated from the main support 2, when the drive motor 301 is controlled to rotate in the same direction and speed, the load-carrying platform 4 and the rescue equipment above it can be conveniently transported to the ground. When the drive motor 301 is controlled to rotate in the same direction but at different speeds, combined with the soft characteristics of the traction wire rope 303, an inclination angle of the load-carrying platform 4 can be formed, and gravity can be used to facilitate the unloading of the rescue equipment on the load-carrying platform 4.

[0082] See Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 Specifically, a slot 401 is provided at the top of the load-carrying platform 4 , and four plug posts 202 are provided at the bottom end of the main frame 2 , and the plug posts 202 are snap-fitted with the slot 401 .

[0083] The connection between the pins 202 and the slots 401 facilitates the precise docking of the load-carrying platform 4 and the main frame 2. This process is applicable to the docking operation before the load-carrying drone 1 takes off, or to the docking operation after the load-carrying drone 1 unloads relief supplies.

[0084] Insertion holes 402 are formed on the side of the slot 401 and the side of the column 202 near the bottom. The locking rod 504 is inserted into the insertion hole 402 after being moved.

[0085] When the post 202 is engaged with the slot 401 and the post 202 reaches the inner bottom of the slot 401, the height value of the hole 402 on the post 202 is equal to the height value of the hole 402 on the slot 401, which facilitates the locking rod 504 to pass through the two holes 402 at one time, thereby locking the engaged post 202 and the slot 401, ensuring the stability of the load-bearing platform 4 and the main bracket 2 after docking.

[0086] An air hole is provided at the inner bottom of the slot 401 to ensure the air pressure balance inside and outside the slot 401 when the pin 202 is engaged with the slot 401 .

[0087] See Figure 1 、 Figure 3 、 Figure 4 , specifically, the four plug posts 202 are slidably connected to the enclosure structure 203;

[0088] The enclosure structure 203 is an integrated structure consisting of four slides 2031, four connecting rods 2032, and a plurality of vertical rods 2033. Each slide 2031 slides along a corresponding plug post 202. The end of each connecting rod 2032 is fixed to a slide 2031. The vertical rods 2033 are evenly distributed on the slides 2031 and the connecting rods 2032.

[0089] A wire mesh 2034 is provided between the slide 2031 and the connecting rod 2032 .

[0090] When the equipment is installed on the load-bearing platform 4, the enclosure structure 203 can be controlled to descend. The slide 2031, connecting rod 2032, vertical rod 2033, and wire mesh 2034 can form an enclosure similar to an inverted box, thereby enclosing the side of the equipment and preventing the equipment from falling from the load-bearing platform 4.

[0091] The enclosure structure 203 is suitable for carrying rescue equipment such as mechanical dogs or transporting supplies to the fire center. When carrying such equipment or supplies, the enclosure structure 203 can prevent such equipment or supplies from falling from the air. When the equipment or supplies descend to the fire center, the enclosure structure 203 is raised, and the tilt of the loading platform 4 is combined with the tilt of the loading platform 4 to facilitate the unloading of the equipment or supplies from the loading platform 4.

[0092] Specifically, a linear module 204 is fixedly installed between the inner top of the main frame 2 and the side of the plug post 202 , and a sliding portion of the linear module 204 is fixed to one of the sliding seats 2031 .

[0093] Through the linear module 204 , the controllable slide 2031 moves up and down, thereby controlling the up and down movement of the entire enclosure structure 203 .

[0094] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 , specifically, the middle part of the load-carrying platform 4 is a hollow structure;

[0095] The hollow structure can reduce the overall weight of the load-carrying platform 4. Since the load-carrying UAV 1 has a limited load-carrying capacity, this can facilitate the load-carrying platform 4 to carry more items.

[0096] The load platform 4 is provided with a plurality of threaded holes 403 , which are arranged at equal intervals, and each threaded hole 403 is close to an edge of the load platform 4 .

[0097] When the equipment carried on the load platform 4 does not need to be unloaded, bolts can be used in conjunction with the threaded holes 403 to more stably fix the equipment on the load platform 4, which is suitable for carrying water tanks, fire extinguishing foam storage boxes, etc.

[0098] A valve can be installed at the bottom of a storage box carrying a water tank, a fire-fighting foam, etc., and the valve can pass through the hollow of the hollow structure to realize aerial firefighting of the storage box carrying a water tank and a fire-fighting foam. At the same time, the second branch line 1032 can be used to connect the signal with the storage box carrying a water tank and a fire-fighting foam, so as to facilitate the integration of the valve signal control into the overall signal control, and ultimately facilitate the signal control of the ground control end.

[0099] Example 3:

[0100] Based on the above-mentioned embodiment 1 and embodiment 2, further description is given.

[0101] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 A control method for a complex optical fiber drone rescue device, wherein the specific implementation steps of the control method include:

[0102] Step 1: Determine the equipment or supplies required at the fire scene: Determine the equipment or supplies to be delivered based on the fire situation. Equipment includes mechanical dogs, water tanks, and fire-fighting foam boxes. Supplies include food and tools.

[0103] Step 2: Install materials or equipment: Use the traction component 3 and the locking component 5 to assist in the docking and locking of the load-carrying drone 1, the main frame 2, and the load-carrying platform 4. Specifically:

[0104] The positioning slot 201 is pushed laterally and engaged with the steel structure clamping plate 106, and then the two are locked by bolts. Then, by utilizing the engagement between the plug column 202 and the slot 401, the plug column 202 needs to reach the inner bottom of the slot 401. At this time, the driving motor 301 controls the rotation of the wire rope around the reel 302 to complete the contraction of the traction wire rope 303 until the traction wire rope 303 is roughly tightened, completing the preliminary docking of the main support 2 and the load-bearing platform 4.

[0105] Then, the micro electric telescopic rod 501 contracts, the push block 502 moves downward, and the connecting piece 503 is used to push the locking rod 504 to move, so that the locking rod 504 passes through the two holes 402 at one time, locking the connected column 202 and the slot 401, ensuring the stability of the load-bearing platform 4 and the main bracket 2 after docking.

[0106] Then, place the materials or equipment on the load-bearing platform 4 and protect or secure them, specifically:

[0107] When the materials or equipment carried are food or rescue tools, such items need to be unloaded from the load-carrying drone 1 to the fire center. At this time, the items are placed on the load-carrying platform 4, and the linear module 204 is used to control the lowering height of the enclosure structure 203 so that the enclosure structure 203 forms an enclosure protection for such items to prevent the items from accidentally falling when the load-carrying drone 1 moves.

[0108] When the carried materials or equipment are water tanks or fire-fighting foam boxes, such items do not need to be unloaded from the load-carrying drone 1, but liquids or solids need to be sprayed in the air. In this case, the items are placed on the load-carrying platform 4, and bolts are passed through the holes of the items and screwed into the threaded holes 403.

[0109] Step 3: Control the load-carrying drone 1 to complete fire rescue: Use the ground control terminal to control the flight of the load-carrying drone 1. During flight, use the master control signal line 101, the air signal line 102, the signal splitter 103, the first branch line 1031, and the second branch line 1032 to form signal transmission, and use the high-definition camera 104 and the strong light lighting beads 105 to obtain the flight route of the load-carrying drone 1.

[0110] For items that need to be unloaded, the load-carrying drone 1 is flown to the top of the unloading position. At this time, the driving motor 301 controls the steel wire rope to rotate around the reel 302, and the traction steel wire rope 303 is released. At the same time, the micro electric telescopic rod 501 extends, the push block 502 moves upward, and the locking rod 504 disengages from the socket 402. As the traction steel wire rope 303 is continuously released, the height of the load-carrying platform 4 and the items decreases. When the load-carrying platform 4 and the items are close to the ground, the release speed of the four traction steel wire ropes 303 is adjusted to make the load-carrying platform 4 form an inclined plane, complete the release of the items, and then the load-carrying platform 4 can be docked with the main bracket 2 again.

[0111] For items that need to be sprayed in the air, after the load-carrying drone 1 flies to a specified height, the corresponding valve is controlled to open on the ground control end to complete the spraying.

[0112] Step 4: Recovery of the load-carrying drone 1: After the rescue is completed, the load-carrying drone 1 is controlled to fly back to a safe place and land, completing a single fire rescue operation;

[0113] Step 5. Determination of rescue results: If the load-carrying drone 1 has not completed the entire fire rescue mission, repeat steps 2, 3, and 4. If the load-carrying drone 1 has completed the entire fire rescue mission, the drone is recovered and the rescue process ends.

[0114] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
