Description

Technical Field

[0001] The utility model relates to the technical field of forestry monitoring unmanned aerial vehicles, in particular to a forestry monitoring unmanned aerial vehicle. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. With the development of science and technology, drones are being used more and more widely, and the technology used for forestry monitoring is becoming increasingly mature. Forestry monitoring refers to the monitoring of ecosystems such as forests, grasslands, and wetlands to understand their health status and changing trends. The purpose is to protect and improve the ecological environment and promote sustainable development.

[0003] UAVs can quickly detect the terrain and plants in forests in real time. Since there are many trees in the forest, a protective cover is usually set on the outside of the propeller to protect the UAV. Since the protective cover and the mechanical arm are usually connected with bolts, when a collision occurs, the collision force is transmitted to the mechanical arm, which is easy to cause damage to the mechanical arm. Therefore, a forestry monitoring UAV is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a forestry monitoring UAV to solve the problem that if the protective cover is subjected to collision force, the mechanical arm is easily damaged.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A forestry monitoring UAV comprises a UAV body for forestry monitoring, a propeller for flying and a mechanical arm for supporting the propeller, wherein the mechanical arm is fixedly connected to one side of the UAV body, the top of the mechanical arm is fixedly connected to a propeller consisting of a rotating shaft and blades, a protective cover with an arc-shaped top is provided on the outer side of the propeller, a fixing plate is fixedly connected to the outer side of the protective cover, fixing bolts for fixing to the mechanical arm penetrate through the fixing plate, a second rubber layer for shock absorption is fixedly connected to the outer side of the protective cover, a damping rod is fixedly connected to one side of the protective cover, a shock-absorbing spring is provided on the outer side of the damping rod, and an anti-collision plate is fixedly connected to one end of the damping rod.

[0007] Preferably, a plurality of air holes are provided on the surfaces of the protective cover, the anti-collision plate and the second rubber layer, and the first rubber layer is fixedly connected to one side of the fixing plate.

[0008] Preferably, the first rubber layer fits tightly to the mechanical arm, a positioning column is fixedly connected to the bottom of the fixing plate, a long bolt is provided at the positioning column, the positioning column is arranged in a recess of the mechanical arm, and the long bolt is inserted from the bottom of the mechanical arm.

[0009] Preferably, a filter screen is tightly fitted on the inner side of the protective cover, and a plurality of Velcro strips are embedded on one side of the filter screen and the protective cover.

[0010] Preferably, the shock absorbing spring is arranged between the second rubber layer and the anti-collision plate, and the anti-collision plate is elastically arranged.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, the protective cover is fixed to the mechanical arm by means of the drone body, mechanical arm, propeller, protective cover, fixing plate, fixing bolts, positioning columns and long bolts. The positioning columns provide a positioning effect when the protective cover is installed. The fixing bolts and the long bolts are used together to increase the fixing effect of the protective cover. The first rubber layer provided on one side of the fixing plate provides a wear-resistant buffering effect at the fixing plate when the protective cover is installed. The plurality of air holes provided on the surfaces of the protective cover, the anti-collision plate and the second rubber layer allow the wind generated by the rotation of the propeller blades to be exchanged with the outside air through the air holes, thereby achieving a ventilation effect. The filter arranged in the protective cover prevents dust in the outside air from entering the protective cover during ventilation, and has a dust-proof effect. The Velcro arranged on the filter and one side of the protective cover facilitates replacement and cleaning of the filter. The elastic anti-collision plate allows the outermost anti-collision plate to play a preliminary buffering role in the event of an accidental collision. The shock-absorbing spring and damping rod arranged on the inner side of the anti-collision plate provide a shock-absorbing effect in the event of a collision. The second rubber layer arranged on the outer side of the protective cover further increases the shock-absorbing and buffering effect at the protective cover. The multi-layer protection structure provided on the protective cover ensures good shock-absorbing and buffering effects in the event of a collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A number of air holes 5 are provided on the surfaces of the protective cover 4, the anti-collision plate 13 and the second rubber layer 16, and a first rubber layer 10 is fixedly connected to one side of the fixing plate 6, so that the protective cover 4 has a breathable effect, and the fixing plate 6 has a buffering effect during installation; the first rubber layer 10 and the mechanical arm 2 are tightly fitted, and a positioning column 8 is fixedly connected to the bottom of the fixing plate 6, and a long bolt 9 is provided at the positioning column 8. The positioning column 8 is set in the recess of the mechanical arm 2, and the long bolt 9 is inserted from the bottom of the mechanical arm 2 to facilitate the installation and fixation of the protective cover 4; a filter screen 11 is tightly fitted on the inner side of the protective cover 4, and a number of Velcro strips 12 are embedded on one side of the filter screen 11 and the protective cover 4, so that it has a dust-proof effect during ventilation, and the filter screen 11 is easy to replace; a shock-absorbing spring 14 is arranged between the second rubber layer 16 and the anti-collision plate 13, and the anti-collision plate 13 is elastically arranged, which increases the shock-absorbing and buffering effect of the protective cover 4.

[0024] Workflow: When the forestry monitoring drone is in use, first place the drone body 1 in a suitable position, start the drone body 1, and control it to rise to a high altitude to monitor the terrain and plants at the forestry location in real time. The blades of the propeller 3 are in a fast rotation state during use. The wind generated by its rotation is exchanged with the outside air through the air vents 5, which plays a ventilation role. The filter 11 set in the protective cover 4 makes it difficult for dust in the outside air to enter the protective cover 4 during ventilation, which has a dust-proof effect. During the process, if the branches of the trees or other things accidentally approach the protective cover 4, they will first collide with the anti-collision plate 13. The elastically set anti-collision plate 13 has a buffering effect on the collision, unloading part of the force. The anti-collision plate 13 shakes due to the collision, and the shock-absorbing spring 14 and the damping rod 15 are set between the anti-collision plate 13 and the protective cover 4. The shock-absorbing spring 14 is in a forward direction. The compressed and bounced state of the anti-collision plate 13 has a shock-absorbing and buffering effect on the protective cover 4 when it shakes. The second rubber layer 16 arranged on the outside of the protective cover 4 further increases the shock-absorbing and buffering effect of the protective cover 4. When the filter 11 needs to be replaced after long-term use, first close the drone body 1 so that it is in a non-working state, turn the long bolt 9 in the loose direction until it is removed, and then remove the fixing bolts 7 in sequence. At this time, the fixing plate 6 can be driven to remove the protective cover 4, and then the filter 11 can be held by hand to tear it off, and then the Velcro 12 embedded in the new filter 11 is aligned with the Velcro 12 in the protective cover 4 and stuck to complete the replacement of the filter 11. Through the multi-layer protection structure set for the protective cover 4, it has a good shock-absorbing and buffering effect when a collision occurs. Through the set air vents 5 and the replaceable filter 11, the protective cover 4 has a dust-proof effect while being breathable.
