[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] This application provides a police drone that solves the technical problem that police drones are prone to failure due to rotor damage or fuselage overturning, making it impossible to quickly return to takeoff status and reducing response efficiency.

[0021] See Figure 1 and Figure 2 As shown in the figure, this application provides a police drone, which includes: a protective cover 1, a drone body 2, and a spray device 3. The drone body 2 is located at the center of the protective cover 1, and a counterweight is installed at the bottom of the drone body 2; the spray device 3 is installed below the drone body 2.

[0022] In this embodiment, the drone body 2 is housed inside the protective cover 1 to prevent damage to the drone body 2 due to direct collision. The counterweight block is installed at the bottom of the drone body 2 to lower the center of gravity of the police drone. This allows the drone body 2 to automatically return to its takeoff state under its own gravity in the event of an accidental fall or overturning, improving the survivability and mission continuity of the police drone. Even if it is blown over by strong winds or tilted due to operational errors during takeoff or landing, the police drone can quickly recover its normal posture and be ready to be used again at any time.

[0023] The spraying device 3 includes a reservoir filled with pepper spray. A nozzle is located at the front end of the reservoir and is adjustable at multiple angles. A miniature water pump is connected to the reservoir. A modular interface is located at the bottom of the drone body 2, through which the spraying device 3 is detachably connected to the drone body 2, allowing for quick installation, removal, and replacement of different mission modules. The miniature water pump is connected to a remote controller, allowing ground operators to remotely control the spraying device 3 to start or stop. The spraying device 3 sprays pepper spray to disperse intruders, serving as a deterrent and warning mechanism. In other embodiments, the spraying device 3 is filled with powder, and it sprays smoke.

[0024] This embodiment prevents damage to the drone body 2 from direct collisions by setting the protective cover 1 around the outer periphery of the drone body 2. By setting the counterweight block at the bottom of the drone body 2, the center of gravity of the police drone is lowered, so that the drone body 2 can automatically return to the takeoff state in the event of an accidental fall or overturn. This solves the technical problem in related technologies that police drones are prone to failure due to rotor damage or fuselage overturning, and cannot quickly return to the takeoff state, resulting in reduced response efficiency.

[0025] Further, see Figure 1-3 As shown, in some embodiments, the protective cover 1 includes two protective cover bodies 11, which are symmetrically arranged along the center of the protective cover 1. The two protective cover bodies 11 are connected by a plurality of crossbeams 12, and the protective cover body 11 is configured as a hemisphere.

[0026] In this embodiment, the protective cover body 11 has a hollow design in the middle to reduce the overall weight of the protective cover 1. The two protective cover bodies 11 are connected by multiple crossbeams 12 to form a spherical protective cover 1.

[0027] Further, see Figure 1-3 As shown, in some embodiments, the protective cover body 11 includes a plurality of interconnected branch plates 111.

The plurality of branch plates 111 are connected to the crossbeam 12 by reinforcing ribs 112, and the plurality of reinforcing ribs 112 are connected to each other by closed loops 113.

[0028] In this embodiment, exemplaryly, six branch plates 111 are evenly arranged along the circumference of the protective cover body 11 and converge at a single point. The six branch plates 111 are hexagonal in shape and bolted to the reinforcing rib 112. All six branch plates 111 are bolted to the crossbeam 12 via the reinforcing rib 112. The closed loop 113 includes multiple interconnected connecting plates. These connecting plates are arc-shaped, with one side connected to the crossbeam 12 and the other side connected to the reinforcing rib 112. In other embodiments, the branch plates 111 are arc-shaped, and multiple branch plates 111 are directly connected to the crossbeam 12. The two connecting plates at the bottom of the protective cover 1 can be horizontal plates to facilitate stable placement of the protective cover 1 on the ground.

Both downward-extending branch plates 111 are bolted to the crossbeam 12 via reinforcing ribs 112. The branch plate 111 extending to the left is bolted to the crossbeam 12 via one arm connector 114, and the branch plate 111 extending to the right is bolted to the crossbeam 12 via another arm connector 114. The two arm connectors 114 are located on the same plane, ensuring that the centers of the two protective cover bodies 11 are located at the center of the protective cover 1, thus improving the stability of the protective cover 1. In other embodiments, the tips of the two arm connectors 114 are inclined downwards, ensuring that the centers of the two protective cover bodies 11 are located on the axis of the protective cover 1 and below the center of the protective cover 1.

[0031] Further, see Figure 1-3 As shown, in some embodiments, right-angle brackets 13 are provided between the reinforcing rib 112 and the closed loop 113, between the arm connector 114 and the closed loop 113, and between the crossbeam 12 and the closed loop 113.

[0032] In this embodiment, the reinforcing rib 112 and the closed loop 113 are connected by the right-angle bracket 13 bolts, and the arm connector is connected to the closed loop 113 by the right-angle bracket 13 bolts, so that the protective cover body 11 forms a hemispherical structure, improving the connection stability of the protective cover body 11. The crossbeam 12 and the closed loop 113 are connected by the right-angle bracket 13 bolts, so that the two protective cover bodies 11 are connected into a whole, improving the connection stability of the protective cover 1.
