Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a fire reconnaissance UAV with smoke-proof effect. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment or self-contained program control devices. They can be divided into two main categories according to their purpose: military and civilian (including industrial and consumer grades). According to their flight platform configuration, they can be divided into fixed-wing, rotary-wing, and airship types. They have advantages such as no risk of personnel casualties, high maneuverability, and low operating costs, and are widely used in reconnaissance, surveying and mapping, logistics, agriculture and other fields.

[0003] Fire reconnaissance drones are a sub-category of civilian drones that are deeply customized for firefighting scenarios. They belong to the category of industrial-grade drones and integrate modules such as infrared thermal imaging, high-definition cameras, and gas detection to achieve functions such as fire scene reconnaissance, high-temperature fire point location, and real-time transmission of disaster information. They are core equipment for improving reconnaissance efficiency and avoiding personnel risks in modern fire rescue.

[0004] In current technology, when fire reconnaissance drones fly over fire sites, their onboard cameras capture real-time images of the fire. However, smoke often exists above the fire site, and this smoke can damage the camera during flight, reducing the smoothness of the lens and decreasing the image clarity, while also shortening its lifespan. Therefore, a fire reconnaissance drone with smoke-proof properties is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that fire reconnaissance drones, during their flight reconnaissance over fire sites, are equipped with cameras that capture real-time images of the fire, while smoke often exists above the fire. This smoke can damage the camera lens, reducing its smoothness, image clarity, and shortening its lifespan. Therefore, a fire reconnaissance drone with smoke-proof properties is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fire reconnaissance drone with smoke-proof effect of this utility model includes a drone body. A camera bracket is vertically suspended at one end of the bottom surface of the drone body. A limiting ring is horizontally fixed to the lower part of the outer wall of the camera bracket. A camera body is symmetrically installed on the side wall of the camera bracket near the end of the drone body. A protective component is provided on the outer wall of the camera body. The protective component includes a lifting ring. A central rotating shaft is vertically fixed at the center of the bottom surface of the inner wall of the lifting ring. Two spherical transparent covers are clamped to the outer wall of the central rotating shaft through a ring. The adjacent side walls of the two spherical transparent covers can coincide with the central cross section of the camera bracket. The two spherical transparent covers are respectively located outside the two camera bodies. An annular groove is opened at one end of the spherical transparent cover. The annular groove can engage with the limiting ring.

[0007] Preferably, the sidewall of the lifting ring is symmetrically provided with installation openings, and wiping cotton is installed inside the installation openings. The two wiping cottons can respectively contact the two spherical transparent covers.

[0008] Preferably, an opening and closing bracket is fixedly connected to the center of the other side wall of the two spherical transparent covers.

[0009] Preferably, the bottom surface of the drone body is provided with two parallel limiting guide rods, the center lines of which are perpendicular to the lifting ring.

[0010] Preferably, a displacement slider is slidably fitted between the outer walls of the two limiting guide rods.

[0011] Preferably, a connecting bracket is fixed to one end of the displacement slider near the side wall where the spherical transparent cover is located. Two arc-shaped connecting rods are symmetrically hinged inside the connecting bracket via a shaft. One end of each of the two arc-shaped connecting rods is respectively hinged to two opening and closing brackets.

[0012] Preferably, an electric telescopic rod is vertically mounted on the bottom surface of the drone body via a bracket, and the telescopic end of the electric telescopic rod is vertically fixed to the center of the side wall of the displacement slider.

[0013] Preferably, a counterweight ball is suspended at the other end of the bottom surface of the drone body.

[0014] The beneficial effects of this utility model are: I. In this utility model, the spherical transparent cover is installed by the cooperation between the central rotating shaft and the limiting ring on the hoisting ring of the protective component. After the two spherical transparent covers are closed with each other, they can protect and shield the camera body, preventing smoke from directly contacting the camera body lens and causing scorching damage, thus ensuring the clarity and service life of the camera body lens.

[0015] Second, in this utility model, the spherical transparent cover, which is installed in cooperation with the limiting ring and the lifting ring, can rotate around the axis under the drive displacement of the displacement slider. During this rotation, the wiping cotton can wipe and clean the surface of the spherical transparent cover that has been exposed to smoke, preventing the accumulation of dust and other impurities on the surface of the spherical transparent cover from causing a decrease in clarity, thereby ensuring the shooting clarity of the camera body.

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

[0018] Specific implementation examples are given below.

[0019] Please see Figure 1 - Figure 4This utility model provides a fire reconnaissance drone with smoke-proof effect, including a drone body 1. A camera bracket 2 is vertically suspended from one end of the bottom surface of the drone body 1. A limit ring 21 is horizontally fixed to the lower part of the outer wall of the camera bracket 2. A camera body 3 is symmetrically installed on the side wall of the camera bracket 2 near the end of the drone body 1. A protective component 4 is provided on the outer wall of the camera body 3. The protective component 4 includes a lifting ring 41. A central rotating shaft 411 is vertically fixed to the center of the bottom surface of the inner wall of the lifting ring 41. Two spherical transparent covers 42 are clamped to the outer wall of the central rotating shaft 411 by a ring. The adjacent side walls of the two spherical transparent covers 42 can coincide with the central cross section of the camera bracket 2. The two spherical transparent covers 42 are respectively located outside the two camera bodies 3. One end is provided with an annular slot 421, which can engage with the limiting ring 21. The camera body 3 is installed under the drone body 1 via the camera bracket 2. As the main device for shooting the scene, the camera body 3 needs to be sealed and protected by the protective component 4 before entering the fire scene with the drone body 1 to prevent the lens of the camera body 3 from being reduced due to the smoke of the fire. The camera bracket 2 is fixed to the central rotating shaft 411 of its side wall limiting ring 21 and the hoisting ring 41, which engages with the annular slot 421 and the bottom ring of the spherical transparent cover 42 respectively, and then the spherical transparent cover 42 is installed, so that the spherical transparent cover 42 can controllably block the camera body 3 by rotating around the axis.

[0020] like Figure 3 and Figure 4 As shown, the side wall of the lifting ring 41 is symmetrically provided with installation openings 412. Wiping cotton 43 is installed inside the installation opening 412. The two wiping cotton 43 can contact the two spherical transparent covers 42 respectively. During the rotation of the spherical transparent cover 42, the wiping cotton 43 installed in the installation opening 412 can wipe and clean the surface of the spherical transparent cover 42 by contacting it.

[0021] like Figure 3 and Figure 4As shown, an opening and closing bracket 422 is fixedly connected to the center of the other side wall of the two spherical transparent covers 42. Two limiting guide rods 44 are installed in parallel on the bottom surface of the drone body 1. The axis of the two limiting guide rods 44 is perpendicular to the lifting ring 41. A displacement slider 45 is slidably fitted between the outer walls of the two limiting guide rods 44. A connecting bracket 451 is fixedly connected to one end of the displacement slider 45 near the side wall of the spherical transparent cover 42. Two arc-shaped connecting rods 46 are symmetrically hinged inside the connecting bracket 451 through a shaft. One end of the two arc-shaped connecting rods 46 is respectively hinged to the two opening and closing brackets 422. An electric telescopic rod 5 is vertically installed on the bottom surface of the drone body 1 through the bracket. The telescopic end of the electric telescopic rod 5 is aligned with the center of the side wall of the displacement slider 45. The vertical connection is fixed at the position. The displacement slider 45 is installed on the arc-shaped connecting rod 46 through the connecting bracket 451. The displacement slider 45 can move radially under the restriction of the limiting guide rod 44. The two arc-shaped connecting rods 46 are respectively hinged to the two opening and closing brackets 422. This allows the spherical transparent cover 42 to open and close relative to the radial movement of the displacement slider 45 under the extension and retraction drive of the electric telescopic rod 5, so as to realize the wiping cotton 43 to wipe and clean the outer wall of the spherical transparent cover 42. During this process, since the inner wall of the spherical transparent cover 42 is attached with a flexible cotton body that can fill the gap between the spherical transparent cover 42 and the camera body 3, it is not easy for foreign objects to enter the spherical transparent cover 42 and obstruct the imaging of the camera body 3 lens.

[0022] like Figure 2 As shown, a counterweight ball 6 is suspended at the other end of the bottom surface of the drone body 1. The counterweight ball 6 can balance the weight difference between the two ends of the bottom of the drone body 1 and increase the flight stability of the drone body 1.

[0023] Working principle: The camera body 3 is installed below the drone body 1 via the camera bracket 2. The camera body 3 serves as the main device for capturing the scene. Before the drone body 1 enters the fire scene, the protective component 4 needs to provide a sealed protective shield for the lens of the camera body 3 to prevent the lens clarity from being reduced due to fire damage. The camera bracket 2 is fixed in place by its side wall limiting ring 21 and the central rotating shaft 411 of the hoisting ring 41, which engages with the annular slot 421 and the bottom ring of the spherical transparent cover 42 respectively. This allows the spherical transparent cover 42 to controllably shield the camera body 3 by rotating around its axis. During the rotation of the transparent cover 42, the wiping cotton 43 installed in the installation opening 412 can wipe and clean the surface of the spherical transparent cover 42 by contacting it. The displacement slider 45 is installed on the arc-shaped connecting rod 46 through the connecting bracket 451, and the displacement slider 45 can move radially under the restriction of the limiting guide rod 44. The two arc-shaped connecting rods 46 are respectively hinged to the two opening and closing brackets 422. This allows the spherical transparent cover 42 to open and close relatively following the radial movement of the displacement slider 45 under the extension and retraction drive of the electric telescopic rod 5, so as to realize the wiping cotton 43 wiping and cleaning the outer wall of the spherical transparent cover 42. The counterweight ball 6 can balance the weight difference between the two ends of the bottom of the drone body 1 and increase the flight stability of the drone body 1.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
