Description

Technical Field

[0001] The present invention relates to the technical field of power supply, and in particular to a power supply system and a use method for an unmanned aerial vehicle laser show. Background Art

[0002] As a dynamic display form that combines flight and visual art, the reliability and functionality of the power supply system of drone performances directly affect the performance effect.

[0003] The existing UAV power supply structure adopts a single set of lithium batteries, which can only meet the long-term flight requirements of the UAV. If a high-power consumption laser device is added, it may not be able to meet the power supply requirements of the entire device system, which will seriously affect the time of the UAV laser show. As a result, there is no UAV laser show system on the market that can meet normal performance needs. Moreover, the existing UAV power supply system cannot increase or decrease lithium batteries according to the operating requirements of the UAV's attached devices. It is impossible to increase the standby time and laser power supply of the UAV by simply adding lithium batteries. There is also a problem of reduced flexibility during use. For this reason, we provide a power supply system for UAV laser show to realize a UAV laser show device that can meet the needs of stage performance scenes. Summary of the Invention

[0004] The purpose of the present invention is to provide a power supply system and a method for use in a UAV laser show, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a power supply system for drone laser performances, comprising a mounting frame, three pluggable concave plates are provided at the bottom of the mounting frame, a heat dissipation and power supply component is provided at the bottom of the concave plates, and the concave plates are connected to the mounting frame by a limiting fixing component.

[0006] In some embodiments, the heat dissipation and power supply component includes a protective shell, there are three protective shells and they are respectively installed at the bottom of three concave plates, a power supply component is installed on the top of the inner wall of the protective shell, and the wires on the top of the power supply component pass through the protective shell and the concave plate from bottom to top and extend to the outside of the concave plate, and heat dissipation ports are opened on both sides of the left and right sides of the protective shell.

[0007] In some embodiments, the limiting fixing assembly includes six plug-in blocks, which are respectively installed on the top of three recessed plates. A slot is provided at the bottom of the front side of the mounting frame corresponding to the position of the plug-in block. The top of the plug-in block passes through the slot and extends to the inside to contact the inner wall of the slot.

[0008] In some embodiments, a slide groove is provided on both the left and right sides of the bottom of the concave plate, a movable slider is provided on the inner wall of the slide groove, a card block is installed on the top of the slider, and a card groove is provided at the top of the inner wall of the slot and at the position corresponding to the card block.

[0009] In some embodiments, a positioning block is installed on the inner wall of the slide groove, and a moving block is installed on the bottom of the slider. The bottom of the moving block passes through the positioning block and the slide groove from top to bottom and extends to the outside of the slide groove. The bottoms of the two moving blocks on the same side and the surface of the protective shell are fixedly connected through a moving frame.

[0010] In some embodiments, a threaded rod is rotatably connected to the inner wall of the moving frame in the groove at the bottom of the concave plate through a bearing, and the bottom end of the threaded rod passes through the moving frame and extends to the outside where a rotating block is installed.

[0011] According to another aspect of the invention, the present invention further provides a method for using a power supply system for a drone laser show, which is applied to the power supply system for a drone laser show described in any of the above embodiments, comprising the following steps:

[0012] S1: Select the number of heat dissipation and power supply components to be installed based on the duration of the drone laser show;

[0013] S2: Align the selected number of inserts on the top of the concave plate with the slots on the bottom of the mounting bracket and insert them until the top of the concave plate contacts the bottom of the mounting bracket;

[0014] S3: Rotate the rotating block to drive the threaded rod to rotate, which drives the moving frame to move upward, so that the card block is embedded in the card slot at the top of the slot;

[0015] S4: Connect the wires of the power supply assembly to the power interface of the drone laser device and flight control system;

[0016] S5: The communication module on the mounting frame monitors the voltage, temperature and remaining capacity of each power component in real time, and uploads the data to the ground control system.

[0017] In some embodiments, in step S3, the rotation direction of the rotating block is clockwise, so that the threaded rod pushes the movable frame to move vertically upward along the surface of the protective shell;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention solves the existing contradiction between single-cell battery life and load capacity by combining three pluggable concave plates with a heat dissipation and power supply assembly. This allows for a drone laser performance device that can meet the needs of stage performances. Furthermore, battery modules can be flexibly added or removed, allowing one to three power supply assemblies to be installed depending on the performance duration. Furthermore, the concave plates and mounting brackets can be easily and conveniently assembled and disassembled, improving ease of assembly and disassembly.

[0023] 2. The method provided by this invention uses step-by-step operation and intelligent monitoring, allowing users to directly select the number and combination of power modules to be installed based on the performance duration. This avoids the heating and lifespan shortening problems caused by forced overloading of traditional single-pack batteries, while also reducing the weight of the drone and improving its flight flexibility and performance stability.

[0024] 3. The power supply component in the present invention can meet the needs of simultaneous lighting of multiple laser beams through the main and auxiliary combination design and protection structure optimization. The lithium battery is used to smooth out power supply fluctuations and can also extend the overall endurance, thereby achieving a balance between high power and long life.

[0041] The combination of three pluggable recessed plates 100 and the heat dissipation power supply component 2 solves the contradiction between the existing single battery pack's battery life and load, thereby allowing for the flexible addition and removal of battery modules. Depending on the performance duration, one to three power supply components 22 can be installed. Furthermore, the process of disassembling and assembling the recessed plates 100 and the mounting frame 1 is simple and convenient, thereby improving the convenience of disassembly and assembly.

[0042] According to another aspect of the invention, the present invention further provides a method for using a power supply system for a drone laser show, which is applied to the power supply system for a drone laser show described in any of the above embodiments, comprising the following steps:

[0043] First, according to the duration requirement of the drone laser show, select the number of heat dissipation and power supply components 2 to be installed, then align the plug blocks 31 on the top of the selected number of concave plates 100 with the slots 32 at the bottom of the mounting frame 1 and insert them until the top of the concave plate 100 contacts the bottom of the mounting frame 1, then rotate the rotating block 311 to drive the threaded rod 310 to rotate, driving the movable frame 39 to move upward, so that the card block 35 is embedded in the card slot 36 at the top of the slot 32, then connect the wires of the power supply component 22 to the power interface of the drone laser device and the flight control system, finally monitor the voltage, temperature and remaining capacity data of each power supply component 22 in real time through the communication module 101 on the mounting frame 1, and upload the data to the ground control system.

[0044] In step S3, the rotating block 311 rotates clockwise, causing the threaded rod 310 to push the moving frame 39 upward vertically along the surface of the protective shell 21; the moving frame 39 drives the moving block 38 and the slider 34 to slide upward synchronously in the slide groove 33, forcing the clamping block 35 to pass through the insert block 31 and engage the clamping groove 36; the bottom end of the threaded rod 310 passes through the moving frame 39 and extends to the outside thereof, where the rotating block 311 is installed. When the top of the rotating block 311 is in close contact with the bottom of the reinforcement block 7, it stops rotating, forming a self-locking structure. In addition, in step S4, if maintenance is required on the power supply assembly 22, first confirm that the drone is in the off state through the communication module 101, then unscrew the fastening bolts 6 on the front of the protective shell 21, remove the inspection panel 5, and then perform the operation. After maintenance is completed, the inspection panel 5 is reinstalled and fixed with the fastening bolts 6.

[0045] The method of use in the present invention realizes minute-level rapid deployment of multiple battery modules through three steps of selecting quantity, plugging and unplugging installation, and rotating locking, thereby greatly ensuring that the drone formation can continuously complete a long-term high-intensity laser show, avoiding the traditional solution that causes formation faults or performance reduction due to battery replacement, thereby providing a guarantee for long-term continuous stage performance effects. At the same time, the modular design supports rapid assembly before the performance, so that in case of on-site maintenance, only the faulty module needs to be replaced, and there is no need to return to the factory for repair, thereby ensuring the continuity of the performance. In addition, the power supply component can adopt a small generator + battery combination. The generator can provide large current at the moment of starting the laser device to meet the demand of lighting multiple laser beams at the same time; at the same time, the lithium battery is used to smooth out power supply fluctuations and extend the overall battery life, effectively improving the practicality of the overall system, so that it can meet the needs of high-intensity stage performances.
