Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to an environmental monitoring UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs), or drones for short, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. UAVs can be categorized into military and civilian applications. In the military field, UAVs are divided into reconnaissance aircraft and target drones. In the civilian field, UAVs combined with industry applications represent a genuine necessity, with a very wide range of applications, including playing a crucial role in environmental monitoring.

[0003] Environmental monitoring involves monitoring and measuring indicators that reflect environmental quality to determine the level of environmental pollution and environmental quality. Soil environmental monitoring is an important measure to understand the status of soil environmental quality. Soil environmental monitoring generally includes steps such as preparation, site selection, sampling, sample preparation, analysis and testing, and evaluation.

[0004] When conducting soil environmental testing and sampling, it is usually necessary to go deep into the target soil layer for sampling. However, in complex terrains (such as mountains and wetlands), it is difficult for both manual labor and sampling machines to enter and operate, which increases the difficulty of sampling. Furthermore, existing drones are often used for single sampling, which is not convenient for sampling multiple times in different areas. If multiple samplings at different locations are required, the drone needs to make multiple round trips, which not only consumes time and effort and increases workload, but also affects the efficiency of the test. Utility Model Content

[0005] The purpose of this invention is to provide an environmental monitoring drone that can perform multiple samplings of different areas at the same destination according to sampling requirements, thereby improving sampling efficiency; and to facilitate subsequent comparative analysis of multiple tests, thus improving the detection effect.

[0006] The specific technical solution adopted by this utility model is as follows: An environmental monitoring drone includes a drone body, the bottom of which is fixedly connected to a collection box. The collection box has a drive cavity inside and multiple sliding grooves on both sides, which are slidably connected to multiple sample boxes respectively. The sampling mechanism includes a drive motor and a rotating plate. The drive motor is fixedly connected to the top of the collection box, and the output end of the drive motor is fixedly connected to a transmission rod. The outer side of the transmission rod is fixedly connected to a spiral blade, and the rotating plate is rotatably connected to the bottom of the drive cavity. The rotating plate has a feeding port, and the drive motor drives the spiral blades to rotate through the transmission rod, thereby transporting the soil into the drive cavity. The sample is then transported into the sample box through the feeding port on the rotating plate to complete the sampling.

[0007] Furthermore, the tops of the plurality of sliding grooves are connected to the bottom of the driving cavity through transmission holes, and the inlet of the sample box corresponds to the transmission hole.

[0008] Furthermore, the rotating plate has a rotating hole at its center, the spiral blade is rotatably connected to the rotating hole, and the rotating plate has teeth on its outer side.

[0009] Furthermore, the teeth are respectively meshed with the drive gear, the top of the drive gear is fixedly connected to the output end of the rotating motor, and the rotating motor is fixed inside the collection box.

[0010] Furthermore, the sampling mechanism includes a scraper fixedly connected to the output end of the drive motor, the scraper being rotatably connected to the interior of the drive cavity, and the bottom of the scraper being slidably connected to the top of the rotating plate.

[0011] Furthermore, a sampling hole is provided at the bottom of the collection box, and the spiral blade is rotatably connected to the sampling hole.

[0012] The technical effects achieved by this utility model are as follows: This utility model discloses an environmental monitoring drone. During the sampling process, the spiral blades effectively cut and transport the soil, ensuring that the soil sample effectively enters the drive chamber. The rotating scraper inside the drive chamber can drive the sample from the feeding hole on the rotating plate into the sample box. After one sampling is completed, the rotating motor is started, which drives the drive gear to mesh with the teeth on the outside of the rotating plate, causing the rotating plate and the feeding hole to rotate. This causes the feeding hole to rotate above another sample box. When the drone body moves the collection box to another area, multiple samplings can be performed in different areas, improving sampling efficiency. Attached Figure Description

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1 to 4 As shown, an environmental monitoring drone includes a drone body 10. The bottom of the drone body 10 is fixedly connected to a collection box 11. The collection box 11 has a drive cavity 111 inside, and multiple sliding grooves 112 are formed on both sides of the collection box 11. The multiple sliding grooves 112 are slidably connected to multiple sample boxes 12 respectively. The sampling mechanism 20 includes a drive motor 21 and a rotating plate 22. The drive motor 21 is fixedly connected to the top of the collection box 11, and the output end of the drive motor 21 is fixedly connected to the transmission rod 211. The outer side of the transmission rod 211 is fixedly connected to the spiral blade 212. The rotating plate 22 is rotatably connected to the bottom of the drive cavity 111. The rotating plate 22 has a feeding port. The drive motor 21 drives the spiral blade 212 to rotate through the transmission rod 211, thereby transferring the soil into the drive cavity 111. The sample is then transported to the sample box 12 through the feeding port on the rotating plate 22 to complete the sampling.

[0017] In this embodiment, it should be noted that the drone is equipped with a remote control device, and a support frame (not shown in the figure) is provided at the bottom of the drone body 10. This support frame is a telescopic support frame, which effectively protects the collection box 11 and sampling mechanism 20 during take-off and landing when the drone is ascending or descending. Simultaneously, during sampling, the drone is controlled to land in the detection area. By controlling the retraction of the support frame, the drone body 10 and sampling mechanism 20 slowly descend and come into contact with the soil. This is a conventional technical method and will not be elaborated upon here. The drone body 10 and sampling mechanism 20... The sampling mechanism 20 is electrically connected and can be effectively controlled to open and close via a drone remote control device. This is a conventional technical method and will not be elaborated on here. Specifically, the drone observes the detection area and moves the collection box 11 to the detection area. The drive motor 21 is started to drive the transmission rod 211 and the spiral blade 212 to rotate. At the same time, the telescopic support frame is controlled to retract, so that the spiral blade 212 can effectively cut and lift the soil, so that the soil can be effectively transferred to the inside of the drive cavity 111. Then, the soil sample is transported to the sample box 12 through the feeding hole opened on the rotating plate 22.

[0018] Preferably, the tops of the multiple sliding grooves 112 are all connected to the bottom of the drive cavity 111 through transmission holes, and the inlet of the sample box 12 corresponds to the transmission hole. It should be noted that the magnetic connection between the sample box 12 and the sliding groove 112 ensures that the sample box 12 will not fall off the sliding groove 112 during the flight of the UAV. Specifically, the transmission hole, the feeding hole and the inlet of the sample box 12 are the same size, and the multiple transmission holes are arranged in a central array along the drive cavity 111.

[0019] like Figure 2 , Figure 4 As shown, a rotating hole is provided in the center of the rotating plate 22, the spiral blade 212 is rotatably connected to the rotating hole, and teeth 221 are provided on the outer side of the rotating plate 22.

[0020] Preferably, the teeth 221 are meshed with the drive gear 23, the top of the drive gear 23 is fixedly connected to the output end of the rotating motor, and the rotating motor is fixed inside the collection box 11.

[0021] In this embodiment, it should be noted that when the rotating motor starts, it drives the drive gear 23 to rotate a specified number of times and then stops. The drive gear 23 meshes with the teeth 221 on the outer side of the rotating plate 22, thereby ensuring that the feeding hole on the rotating plate 22 always corresponds to the position of the transmission hole. After one sampling is completed, the rotating motor is controlled to drive the drive gear 23 to interact with the rotating plate 22 and drive the rotating plate 22 to rotate, so that the rotating plate 22 moves the feeding hole from above the sample box 12 after sampling to above another adjacent sample box 12. By controlling the rotating plate 22 to drive the feeding hole to cooperate with multiple sample boxes 12 in sequence, it is possible to ensure the separate storage of multiple samples, improve sampling efficiency, and ensure that samples are not mixed.

[0022] like Figure 2 , Figure 3 As shown, the sampling mechanism 20 includes a scraper 24 fixedly connected to the output end of the drive motor 21. The scraper 24 is rotatably connected to the inside of the drive cavity 111, and the bottom of the scraper 24 is slidably connected to the top of the rotating plate 22. It should be noted that when the drive motor 21 is started, it will synchronously drive the scraper 24 to rotate inside the drive cavity 111, so that the scraper 24 pushes the sample above the rotating plate 22, thereby effectively transferring the sample to the sample box 12 through the feeding hole.

[0023] like Figure 3 , Figure 4 As shown, a sampling hole 113 is provided at the bottom of the collection box 11, and the spiral blade 212 is rotatably connected to the sampling hole 113. Specifically, when the drive motor 21 drives the spiral blade 212 to rotate, the spiral blade 212 crushes and transports the soil. The sampling hole 113 ensures that the soil will not leave the track of the spiral blade 212 during the transport process, and ensures that the soil sample is stably transported into the drive cavity 111.

[0024] The working principle of this utility model is as follows: During environmental monitoring, the drone body 10 moves the collection box 11 to the monitoring area. Then, the drone body 10 lands, and the drive motor 21 starts simultaneously. The transmission rod 211 drives the spiral blades 212 to rotate, and the support rod retracts, causing the spiral blades 212 and the collection box 11 to slowly approach the soil. The spiral blades 212 cut and pulverize the soil. When the collection box 11 approaches the ground, it forms a closed transmission channel with the sampling hole 113 at the bottom, thus transferring the soil through the spiral blades 212 to the rotating plate 2 at the bottom of the drive chamber 111. 2. When the drive motor 21 starts, it will synchronously drive the scraper 24 to rotate inside the drive cavity 111, so that the bottom of the scraper 24 pushes the soil on the rotating plate 22, thereby ensuring that the soil enters the sample box 12 from the feeding hole. After one sampling is completed, the rotating motor is started by controlling it to drive the drive gear 23 to mesh with the teeth 221 on the outside of the rotating plate 22, thereby driving the rotating plate 22 and the feeding hole to rotate, so that the feeding hole rotates to the top of another sample box 12. Thus, when the drone body 10 is controlled to move the collection box 11 to another area, multiple samplings of different areas can be performed to improve sampling efficiency.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
