Description

Technical Field

[0001] This utility model relates to the field of spraying drone technology, and in particular to a protective device for spraying drones. Background Technology

[0002] With the development of agricultural modernization, spraying drones have been widely used in the field of agricultural plant protection. During the flight of drones, collisions often occur due to operator carelessness or airflow, requiring the use of protective devices to protect the drones.

[0003] For example, CN218258696U discloses a protective device for pesticide spraying drones, including a drone body with a spraying device installed on it; multiple sleeves are fixed to the lower end of the drone body, and vertically sliding support feet are provided in the sleeves, with the lower end of the support feet passing through the sleeves and positioned below the sleeves; a first connecting rod is hinged to the outer end of the sleeves, and a second connecting rod is hinged to the outer end of the support feet, with the first and second connecting rods hinged and fixed; a third connecting rod is hinged to the outermost end of the first connecting rod, and the other end of the third connecting rod is detachably connected to the drone body.

[0004] In existing technologies, when a drone is hit by a collision, the high-speed rotating fan blades are more likely to be damaged when they collide with foreign objects. Most protective devices are designed to protect the drone's fuselage but cannot protect the fan blades simultaneously. When the fan blades are hit, the drone may malfunction, and in severe cases, the drone may fall directly, affecting the spraying operation. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a protective device for spraying drones, including a fixed plate 1. Protective mechanisms 3 are installed at each of the four corners of the fixed plate 1. An installation mechanism 2 is installed on one side of the fixed plate 1, and a buffer mechanism 4 is installed on the other side. The protective mechanism 3 includes an installation frame 33. A support plate 34 is fixedly connected to one side of the installation frame 33. A connecting plate 32 is fixedly connected to one end of the support plate 34. A movable plate 36 is slidably connected to the inner side of the connecting plate 32. A second threaded rod 35 is threadedly connected to the inside of the movable plate 36, and one end of the second threaded rod 35 is rotatably connected to the connecting plate 3. At one end of the movable plate 36, a fixed plate 31 is fixedly connected to one end of the plate 2. A connecting column 38 is fixedly connected to one side of the fixed plate 31. A protective net 37 is fixedly connected to one end of the connecting column 38. An arc-shaped plate 310 is fixedly connected to the outside of the connecting column 38. A crash pad 39 is fixedly connected to the outside of the arc-shaped plate 310. The buffer mechanism 4 includes a landing bracket 42. One end of the landing bracket 42 is rotatably connected to one side of the fixed plate 1. A fixed rod 43 is fixedly connected to the outside of the landing bracket 42. A shock absorber 41 is installed in the middle of the fixed rod 43. One end of the shock absorber 41 is installed on one side of the fixed plate 1.

[0025] The device is installed on the drone via the mounting mechanism 2. Rotating the second threaded rod 35, which is threadedly connected to the movable plate 36, causes the movable plate 36 to move. Simultaneously, the movable plate 36 is slidably connected to the connecting plate 32, fixing the movable plate 36 in a linear motion. This movement of the movable plate 36 changes the position of the fixed disk 31, causing the fixed disk 31 and the protective net 37 to fit over the outside of the drone's fan blades. An arc-shaped plate 310 and a collision pad 39 are provided around the outer ring of the protective net 37 to protect the fan blades and reduce damage from impacts. Simultaneously, through the cooperation of the shock absorber 41, the landing bracket 42, and the fixed rod 43, when the drone lands, the landing bracket 42 contacts the ground, and the shock absorber 41 deforms to buffer and reduce shock, thus mitigating the impact on the drone. This provides simultaneous protection for both the drone's fan blades and fuselage, reducing damage and improving the overall protection effect.

[0026] Example 2: Figure 1 and Figure 4As shown, the mounting mechanism 2 includes a fixed frame 21, with the four corners of the fixed frame 21 fixedly connected to the mounting frame 33. A first threaded rod 23 is rotatably connected inside the fixed frame 21. Moving blocks 27 are threadedly connected to both sides of the middle part of the first threaded rod 23. A rotating rod 26 is rotatably connected to one end of the two moving blocks 27. A push plate 25 is rotatably connected to one end of the rotating rod 26. A connecting rod 28 is fixedly connected to one end of the push plate 25. A clamping plate 29 is fixedly connected to one end of the connecting rod 28. A first sliding groove 22 is opened on one side of the fixed plate 1, and the interior of the first sliding groove 22 is slidably connected to the moving blocks 27. A second sliding groove 24 is opened on one side of the fixed plate 1, and the end of the push plate 25 is slidably connected to the second sliding groove 24.

[0027] The overall effect of this embodiment is that by rotating the first threaded rod 23, whose threads on both sides of the middle section are set in opposite directions, the two threaded moving blocks 27 are driven to move. The bottom end of the moving block 27 slides inside the first slide groove 22. The fixed moving block 27 makes linear motion, which drives the rotating rod 26 to rotate and pushes the two push plates 25 to move. The push plates 25 slide inside the second slide groove 24. The fixed push plates 25 make linear motion, which in turn drives the connecting rod 28 and the clamping plate 29 to move. Through the cooperation between the two clamping plates 29, the entire device is fixed on the drone, which facilitates the installation and removal of the protective device, thereby protecting the drone and improving its service life.

[0028] The usage and working principle of this device are as follows: By rotating the first threaded rod 23, the two moving blocks 27 are driven to move. The rotating rod 26 rotates, pushing the two push plates 25 to move, which in turn drives the connecting rod 28 and the clamping plate 29 to move. Through the cooperation between the two clamping plates 29, the entire device is fixed on the drone. By rotating the second threaded rod 35, the moving plate 36 moves, which drives the position of the fixed plate 31 to change. The fixed plate 31 and the protective net 37 are placed on the outside of the drone's fan blades. The fan blades are protected by the arc plate 310 and the anti-collision pad 39 to reduce the impact damage to the fan blades. When the drone lands, the landing bracket 42 contacts the ground, and the shock absorber 41 deforms to buffer and reduce the impact on the drone.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
