Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an unmanned equipment retrieval device and method. Background Technology

[0002] In applications such as drones, marine instruments, and field equipment, rapid retrieval after accidental crashes (especially in water or complex mountainous terrain) poses a significant challenge. Existing technologies, such as standalone GPS locators, acoustic beacons, or buoys, generally suffer from functional fragmentation, poor environmental adaptability, or insufficient battery life: GPS relies on signals and lacks active tracing; acoustic / smoke modules are prone to water ingress and failure; pure buoys lack positioning capabilities; and solar power often neglects sealing and energy management. There is an urgent need for a reliable retrieval device that integrates multimodal tracing (visual / auditory / positional), active buoyancy, waterproof sealing, and intelligent energy management to meet the all-weather retrieval needs in complex environments.

[0003] Most existing drone recovery devices rely on the drone itself still being operational after being lost. Therefore, the chances of recovering a drone that has lost its functionality are relatively low. For example, when a drone is lost, it is in a state without power. All methods, such as wireless positioning, sound, and smoke, require power to be triggered, so the probability of recovery is low. Summary of the Invention

[0004] The purpose of this invention is to provide an unmanned equipment retrieval device and method to solve the problems mentioned in the background art.

An air box containing compressed gas is provided outside the connecting plate. Multiple sets of circumferentially arrayed energy replenishing plates are rotatably mounted outside the connecting plate. Solar panels are mounted on the energy replenishing plates. The inner side of the energy replenishing plates is connected to the air box via a folded tube and the connecting plate. When the energy replenishing plates are retracted, their ends can be electromagnetically fixed to the mainboard compartment. The solar panels are electrically connected to the mainboard compartment via a cable passing through the folded tube and the connecting plate. A rigid conductive arc rod extending along the folded tube is connected to the end of the cable. A rubber plug is provided at the connection point between the end of the cable and the rigid conductive arc rod. A stepped groove is provided at the connection point between the folded tube and the connecting plate. The rubber plug is pressed against the stepped surface of the stepped groove. The outer diameter of the rubber plug is smaller than the inner diameter of the folded tube.

[0008] Preferably, the end of the energy replenishing plate is provided with a magnetic suction plate, and the main board compartment is provided with an electromagnetic block at the position opposite to the end of the folded energy replenishing plate, and the electromagnetic block and the magnetic suction plate are attracted to each other.

[0009] Preferably, a backup battery is provided inside the connecting plate. One end of the backup battery is electrically connected to the solar panel via a cable, and the other end of the backup battery is connected to the main battery in the main board compartment via a wire passing through the inner cavity of the telescopic pipe.

[0010] Preferably, the side of the connecting plate is provided with multiple sets of rotating seats arranged in a circumferential array, and the end of the energy replenishing plate is rotatably mounted on the rotating seats.

[0011] Preferably, the lower end of the energy replenishment plate is provided with a right-angle airbag plate, the vertical section of the right-angle airbag plate is fixed between the magnetic plate and the solar panel, the horizontal plate of the right-angle airbag plate is distributed along the back of the solar panel, the lower end of the energy replenishment plate is provided with a storage compartment, and a connecting air passage is provided horizontally inside the connecting plate.

[0013] A retrieval method based on the aforementioned unmanned equipment retrieval device, the method comprising the following steps: Step 1: The motherboard continuously monitors the main battery voltage while the device is powered off. When the voltage is ≤3.3V, the solar panel will automatically start charging, and charging will stop when the voltage reaches 3.8V. Step 2: When the solar panel needs to be unfolded, release the fixation on the end of the supplementary energy panel.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention uses an electromagnetically fixed power replenishment plate. When the unmanned equipment is lost and loses power, the power failure causes the power replenishment plate to be released and unfold under air pressure, thereby achieving the purpose of recharging. After recharging, it can provide secondary power to various alarm methods such as wireless positioning, sound, and smoke on the retrieval equipment, thus greatly improving the retrieval probability.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 7The present invention provides a technical solution: An unmanned equipment retrieval device includes a mainboard compartment 1. An adjustable-length telescopic pipe 3 is provided on one side of the mainboard compartment 1. A connecting plate 5 is provided at the end of the telescopic pipe 3. An air box 6 with built-in compressed gas is provided on the outside of the connecting plate 5. Multiple sets of circumferentially arrayed energy replenishing plates 4 are rotatably mounted on the outside of the connecting plate 5. Multiple sets of circumferentially arrayed rotating seats 51 are provided on the side of the connecting plate 5. The ends of the energy replenishing plates 4 are rotatably mounted on the rotating seats 51.

[0019] The energy replenishment plate 4 can be rotated and installed by setting a rotating seat 51.

[0020] A solar panel 41 is installed on the energy replenishment plate 4. The inner side of the energy replenishment plate 4 is connected to the gas box 6 through the folding tube 7 and the connecting plate 5. When the energy replenishment plate 4 is stored, its end can be electromagnetically fixed to the main board compartment 1. The solar panel 41 is electrically connected to the main board compartment 1 through the cable 8 that passes through the folding tube 7 and the connecting plate 5. The end of the cable 8 is connected to a rigid conductive arc rod 81 that extends along the folding tube 7. A magnetic suction plate 43 is installed at the end of the energy replenishment plate 4. An electromagnetic block 15 is installed in the main board compartment 1 at the position opposite to the end of the folded and stored energy replenishment plate 4. The electromagnetic block 15 and the magnetic suction plate 43 attract each other.

[0021] With the electromagnetic block 15 and the magnetic suction plate 43 magnetically fixed, the energy replenishment plate 4 is in a folded and stored state. In this state, the rigid conductive arc rod 81 squeezes the rubber plug 57, causing it to seal the position of the stepped groove 55, thereby realizing the separation of the air box 6 and the folded tube 7.

[0022] A rubber plug 57 is provided at the connection position between the end of the cable 8 and the rigid conductive arc rod 81. A stepped groove 55 is provided at the connection position between the folded tube 7 and the connecting plate 5. The rubber plug 57 is pressed onto the stepped surface of the stepped groove 55. The outer diameter of the rubber plug 57 is smaller than the inner diameter of the folded tube 7.

[0023] By limiting the outer diameter of the rubber plug 57, it is ensured that when the folded tube 7 expands and the energy replenishment plate 4 rotates and unfolds, the rubber plug 57 can be pulled into the folded tube 7 to adapt to the rotation and unfolding of the energy replenishment plate 4.

[0024] A cigarette holder 2 for holding cigarette pellets is provided on one side of the mainboard compartment 1. A cigarette lighting device 12 for lighting cigarette pellets in the cigarette holder 2 is provided in the mainboard compartment 1, which is controlled by the mainboard 13. A buzzer 11 and a main battery 14 for powering the mainboard 13 are provided in the mainboard compartment 1. A GPS component for positioning is provided in the air box 6. An LED light strip is provided on the outer edge of the power supply plate 4. An ejection device is provided at the connection position between the telescopic pipe 3 and the mainboard compartment 1. The ejection device is driven by a compression spring or an air pump. After being triggered, it can eject the mainboard compartment 1 and the cigarette holder 2 holding the cigarette pellets to a preset height.

[0025] By setting up the cigarette lighter device 12 and the cigarette holder 2 together, the purpose of smoke alarm is achieved; by setting up the GPS component, wireless positioning is achieved; by setting up the LED light strip and the buzzer 11, the sound and light alarm is achieved. By integrating multiple alarm methods, the probability of the device being found is increased. By setting up the ejection device, the main board compartment 1 and the cigarette holder 2 holding the cigarette are ejected, thereby increasing the visual range of the alarm.

[0026] A backup battery 53 is installed inside the connecting plate 5. One end of the backup battery 53 is electrically connected to the solar panel 41 via a cable 8, and the other end of the backup battery 53 is connected to the main battery 14 in the main board compartment 1 via a wire passing through the inner cavity of the telescopic pipe 3. A right-angle airbag plate 42 is installed at the lower end of the energy replenishing plate 4. The vertical section of the right-angle airbag plate 42 is fixed between the magnetic plate 43 and the solar panel 41. The horizontal plate of the right-angle airbag plate 42 is distributed along the back of the solar panel 41. A storage compartment 44 is installed at the lower end of the energy replenishing plate 4. A connecting air passage 52 is arranged horizontally inside the connecting plate 5. The right-angle airbag plate 42 is connected to the air box 6 through the storage compartment 44, the folding pipe 7, and the connecting air passage 52.

[0027] When the main battery 14 fails to provide power, or after the motherboard compartment 1 is ejected, the backup battery 53 is powered by the power supply board 4 to continuously power the GPS components, LED light strips, etc.

[0028] An extension airway 54 is vertically arranged inside the connecting airway 52. ​​A piston wheel seat 58 is slidably installed inside the extension airway 54. A piston that slides along the inner wall of the extension airway 54 is arranged on the piston wheel seat 58. A steering wheel is arranged on the other side of the piston wheel seat 58. The cable 8 extends and bends along the steering wheel.

[0029] By setting the piston wheel seat 58, the cable 8 is limited and folded, so that its length is adapted to the unfolding and storage of the energy replenishment plate 4. The piston on the piston wheel seat 58 slides in the extension air passage 54, so that the internal pressure of the air box 6 controls its position. Initially, the air box 6 stores compressed gas and the internal pressure is large. The piston wheel seat 58 is located at the deepest part of the extension air passage 54, which is adapted to the state of the energy replenishment plate 4 at this time.

[0030] A retrieval method based on an unmanned equipment retrieval device includes the following steps: In the initial state, the retrieval device is installed on the unmanned equipment, and the power supply is used to fold and fix the energy replenishment plate 4. If the GPS coordinates do not change for 3 minutes, a loss warning is sent. The operator can manually handle this to identify the device status and prevent misjudgment. If there is no response for 1 minute, a control failure may occur, and the device will automatically enter the loss state. When the device is determined to be in the loss state, the power supply to the electromagnetic block 15 is controlled to release the fixation of the end of the energy replenishment plate 4. At this time, the pressure inside the air box 6 causes the rubber plug 57 to separate from the stepped groove 55, and the gas enters the folding tube 7, causing it to expand and unfold.

[0031] After the device is identified as lost, if it remains powered on, it will be connected to the remote control. The mainboard 13 will automatically increase the power of the GPS and receiver, and continuously send the device's latitude and longitude information to the remote control. At the same time, the cigarette warning function, the light function, and the buzzer function will be unlocked.

[0032] After the cigarette lighting function is turned on, the cigarette lighting device 12 will generate a high temperature without an open flame to ignite the smoke pellet. The cigarette lighting function can only be used once and cannot be used again after it has been turned on.

[0033] After turning on the lighting function, the LED light strip set on the outer edge of the power supply plate 4 will be turned on.

[0034] After the buzzer function is turned on, buzzer 11 will start to emit an alarm sound. The operator can also manually turn off the buzzer function via remote control.

[0035] If the remote control is disconnected at this time, that is, the device is powered off, the device will enter the control search mode.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
