[0002] An explosion-proof unmanned aerial vehicle is a kind of unmanned aerial vehicle specially designed for performing tasks in flammable and explosive environments, which has a strong shell and a reliable flight control system. It is usually made of aerospace special metal materials to make the body light and solid, which can effectively resist external impact and fragments generated by explosion. At the same time, the flight of the unmanned aerial vehicle completely depends on the electric energy provided by the battery.

[0003] For example, an explosion-proof unmanned aerial vehicle capable of improving the detection sensitivity of the unmanned aerial vehicle in the event of a collision accident is disclosed in Chinese authorized publication No. CN 217706278 U.

[0004] However, most of the current explosion-proof unmanned aerial vehicles only focus on the explosion-proof of the body, and do not have good protection function for the battery, which may still be damaged after colliding with objects and cause safety hazards such as explosion, thereby shortening the overall service life and having certain defects. CONTENT OF THE UTILITY MODEL

[0007] The explosion-proof unmanned aerial vehicle comprises: an unmanned aerial vehicle body, a first protective plate and a deflector, the inner side middle part of the unmanned aerial vehicle body is provided with a battery compartment, and the inside of the battery compartment is provided with a battery inserted therein, and the lower end connecting part of the battery and the battery compartment is provided with an elastic clamping block;

[0008] The lower end middle part of the unmanned aerial vehicle body is provided with a first protective plate, and the lower end left and right sides of the first protective plate are both provided with a damper, the lower end outer side of the damper is connected with a connecting plate, and the lower end outer side of the connecting plate is fixedly provided with a second protective plate;

[0009] The outer side of the connecting plate is connected with a deflector located on the inner side of the lower end of the unmanned aerial vehicle body, and prefabricated grooves are formed at equal intervals on the outer side of the deflector.

[0010] Further, the left and right outer sides of the unmanned aerial vehicle body are both provided with a wing assembly, and the left and right outer sides of the lower end of the unmanned aerial vehicle body are both fixedly provided with a support foot.

[0011] Further, the first protective plate is located directly below the battery, and an upper end of the first protective plate is integrally fixed with a T-shaped block extending into the unmanned aerial vehicle body, and the T-shaped block is connected to the unmanned aerial vehicle body in a sliding manner.

[0012] Further, the lower end of the flow guide plate extends to the outside of the lower end of the unmanned aerial vehicle body, and a limiting block is fixedly installed on the outside of the end of the flow guide plate close to the central axis of the unmanned aerial vehicle body.

[0013] Further, a limiting rod is installed inside the lower end of the unmanned aerial vehicle body and penetrates the limiting block, and the limiting rod is connected to the limiting block in a sliding manner.

[0014] Further, a cavity is formed inside the lower end of the unmanned aerial vehicle body and located outside the battery compartment, and a dustproof screen is attached to the cavity and located outside the battery compartment.

[0015] Further, the connecting plate and the flow guide plate are connected in a sliding manner.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 3 As shown, the explosion-proof drone in the first aspect embodiment of this application includes: a drone body 1, a first protective plate 7 and a guide plate 11. Wing assemblies 2 are installed on the outer sides of both the left and right ends of the drone body 1, and support feet 3 are fixedly installed on the lower left and right sides of the drone body 1. The combination constitutes the explosion-proof drone as a whole. The motor installed inside the drone body 1 and the motor installed on the outer side of the wing assembly 2 are both provided with a shell. The motor is protected by a lightweight metal explosion-proof shell to ensure that the sparks generated by the motor during operation in dangerous places will not pose a threat to the surrounding environment. The design pressure of the shell is set at 1.5 MPa.

[0028] Meanwhile, the outer side of the unmanned aerial vehicle body 1 is provided with an explosion-proof housing, which is protected by the explosion-proof housing of the explosion-proof and intrinsically safe type. The battery and the core control are protected by respectively arranging the cavity of the independent battery and the control cavity, and the battery and the control are protected respectively. The safety of the battery and the control in dangerous places and the threat of the battery and the control itself to the surrounding flammable and explosive places are ensured. The explosion-proof housing can withstand the explosion pressure generated by the explosion of the internal mixed gas, and can prevent the internal explosion flame and high-temperature gas from escaping the explosion gap and igniting the explosive mixture around the housing, so as to play the role of explosion-proof.

[0029] The inner side of the unmanned aerial vehicle body 1 is provided with a battery compartment 4, and the inner side of the battery compartment 4 is provided with a battery 5. The lower end of the battery 5 and the battery compartment 4 is provided with an elastic clamping block 6. The battery compartment 4 is installed in the lower end of the unmanned aerial vehicle body 1 by screws. When the battery 5 needs to be installed, the battery 5 is inserted into the battery compartment 4 from bottom to top. With the insertion of the battery 5, the elastic clamping block 6 is clamped with the battery 5, so as to improve the installation and fixing effect of the battery 5.

[0030] The lower end of the unmanned aerial vehicle body 1 is provided with a first protective plate 7, which is located directly below the battery 5. The upper end of the first protective plate 7 is integrally fixed and installed with a T-shaped block extending into the unmanned aerial vehicle body 1. The first protective plate 7 has a good protective effect on the lower end of the battery 5, avoiding the exposure of the lower end of the battery 5 to the air.

[0031] The lower end of the first protective plate 7 is provided with a damper 8 on the left and right sides. The lower end of the damper 8 is connected with a connecting plate 9, and the lower end of the connecting plate 9 is fixedly installed with a second protective plate 10. The lower end of the second protective plate 10 is provided with a rubber sheet. The first protective plate 7 has a good installation effect on the damper 8, which facilitates the installation of the second protective plate 10 on the outer side of the lower end of the first protective plate 7 through the damper 8 and the connecting plate 9. When the second protective plate 10 is impacted by the outside, the damper 8 can buffer the impact force of the second protective plate 10, reducing the impact force. At the same time, the second protective plate 10 can protect the lower end of the first protective plate 7, improve the protection effect of the battery 5, and avoid damage to the battery 5.

[0032] The outer side of the adapter plate 9 is connected with the guide plate 11 located in the inner side of the lower end of the unmanned aerial vehicle body 1, the lower end of the guide plate 11 extends to the outer side of the lower end of the unmanned aerial vehicle body 1, and the outer side of the guide plate 11 is provided with prefabricated grooves 14 at equal intervals, the inner side of the lower end of the unmanned aerial vehicle body 1 is provided with a cavity located on the outer side of the battery compartment 4, and a dust screen 15 located on the outer side of the battery compartment 4 is attached in the cavity. The adapter plate 9 has a good limiting effect on the guide plate 11. When the unmanned aerial vehicle body 1 is flying, the guide plate 11 and the prefabricated grooves 14 have a good guiding effect on the air, which facilitates the introduction of air into the cavity. At this time, the dust screen 15 can filter the air to prevent impurities from entering the unmanned aerial vehicle body 1. The filtered air can enter the interior of the battery compartment 4 through the through holes formed in the outer wall of the battery compartment 4, thereby facilitating the cooling and heat dissipation of the battery 5 and avoiding the phenomenon that the high temperature of the battery 5 affects the flight effect.

[0033] The outer side of the one end of the guide plate 11 close to the central axis of the unmanned aerial vehicle body 1 is fixedly installed with a limiting block 13, and the inner side of the lower end of the unmanned aerial vehicle body 1 is installed with a limiting rod 12 penetrating into the limiting block 13, and the limiting rod 12 and the limiting block 13 are connected in a sliding manner. When the damper 8 buffers the impact force received by the second protective plate 10, the damper 8 shortens and drives the second protective plate 10 and the adapter plate 9 to move upward. At this time, the guide plate 11 moves synchronously with the adapter plate 9 under the driving of the adapter plate 9, and the limiting block 13 and the limiting rod 12 slide, thereby ensuring the stability of the movement of the guide plate 11 and facilitating the retraction of the lower end of the guide plate 11 to avoid damage to the guide plate 11 caused by collision.

[0034] The T-shaped block and the unmanned aerial vehicle body 1 are connected in a sliding manner, and the adapter plate 9 and the guide plate 11 are connected in a sliding manner. When the battery 5 is installed and disassembled, the first protective plate 7 can be pulled forward, so that the first protective plate 7 drives the damper 8, the adapter plate 9 and the second protective plate 10 to move forward, so that the lower end of the battery 5 is exposed in the air, thereby avoiding blocking the battery 5 and improving the use effect.

[0035] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradictory). In order to make the description simple, not all possible combinations of the technical features in the above embodiments are described. The embodiments not explicitly written should also be considered as the scope of the present application.
