Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a multi-point water sampling device for environmental monitoring. Background Technology

[0002] As is well known, in the current field of environmental monitoring, multi-point sampling of water bodies is an important basis for assessing water quality, monitoring changes in water pollution, and formulating environmental protection measures. Traditional water sampling methods often rely on manual operation. However, manual sampling faces many challenges, such as high safety risks, low sampling efficiency, and limited sampling locations.

[0003] Specifically, traditional artificial water sampling is not only time-consuming and labor-intensive, but also limited by conditions such as terrain and water depth, making it difficult to achieve comprehensive and accurate sampling of a wide area of ​​water. Especially in complex or dangerous water environments, it is even more difficult to accurately reach the predetermined sampling point. At the same time, it is also easily affected by external factors such as water flow and wind, resulting in inaccurate sampling results, which is very inconvenient. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A multi-point water sampling device for environmental monitoring includes a drone 3, a telescopic device, and a suction head 7. A protective box 9 is located at the center of the bottom wall of the drone 3. The telescopic device is located at the lower end of the protective box 9 and includes a support box 5, a rotating rod 11, and a lifting block 12. The upper side wall of the support box 5 is connected to the bottom wall of the protective box 9. A cavity is provided inside the support box 5, and the rotating rod 11 passes through the cavity. A rotating motor 10 is located inside the protective box 9, passing through the upper side wall of the protective box 9 and connected to the output end of the rotating motor 10. The lifting block 12 is located on the rotating rod 11, and the rotating rod 11 passes through the lifting block 12 and is threadedly connected to it. The lifting block 12 is adapted to the cavity. The device is equipped with a sliding connection. The bottom wall of the lifting block 12 is provided with a connecting plate 6. The water suction head 7 is located on the bottom wall of the connecting plate 6. The upper end of the water suction head 7 is provided with a connecting pipe 4 with a water pump. The connecting pipe 4 passes through the connecting plate 6. The upper side wall of the drone 3 is provided with a sampling bucket 1. The output end of the water pump in the connecting pipe 4 passes through the lower end of the side wall of the sampling bucket 1. The upper side wall of the sampling bucket 1 is provided with a protective cover 2. The protective cover 2 is detachably connected to the sampling bucket 1. The inner side wall of the protective cover 2 is provided with a camera 14. The device is equipped with a remote control system. The side wall of the support box 5 is provided with a through laser scale line 8. The upper end of the lifting block 12 is provided with a laser emitter 13. The laser emitter 13 is signal connected to the laser scale line 8.

[0025] During use, the device is first assembled, ensuring that all parts, including the drone 3, telescopic device, suction head 7, and sampling bucket 1, are securely connected and functioning properly. The clarity of the camera 14 is checked via the remote control system to ensure real-time transmission of clear images. Based on sampling requirements, the coordinates of the sampling points are preset. The drone 3 is then launched, controlled by the remote control system to take off and fly to the preset sampling area. Using the positioning system on the drone 3, it accurately reaches the airspace above the first sampling point. The required sampling depth value is then set via the remote control system, which converts the set value into an electrical signal and sends it to the laser emitter 13. Upon receiving this signal, the laser emitter 13 immediately starts emitting a laser beam, which will serve as the basis for subsequent depth positioning. Simultaneously, the remote control system sends a start signal to the rotating motor 10. Upon receiving the signal, the rotating motor 10 outputs a signal to cause the rotating rod 11 to rotate. Under the limit of the support box 5, the lifting block 12 descends with the rotation of the rotating rod 11. At this time, the laser emitter 13 continuously emits a laser beam and interacts with the laser. The laser scale line 8 on the side wall of the support box 5 is compared. When the water suction head 7 reaches the preset sampling depth, the preset depth position on the laser scale line 8 corresponds to the set sampling depth value. At this time, the signal of the laser emitter 13 is aligned with the preset depth position on the laser scale line 8. This alignment state is captured by the laser emitter 13 and converted into a position signal. The laser emitter 13 sends the position signal to the remote control system. The remote control system then stops rotating the motor 10, fixes the position of the water suction head 7, and starts the water pump through the remote control system. The water pump starts working and sucks water into the sampling bucket 1 through the connecting pipe 4. The camera 14 transmits images of the sampling process in real time. The operator can observe the sampling situation through the remote control system to ensure the sampling quality. When the water sample in the sampling bucket 1 reaches the preset amount, the water pump is turned off and the sampling stops. The drone 3 is controlled by the remote control system to rise, fly away from the current sampling point, go to the next sampling point or return to the take-off point. After the drone 3 returns, the motor is turned off, the power is disconnected, and it lands safely. The protective cover 2 of the sampling bucket 1 is opened, and the water sample is taken out for subsequent environmental testing and analysis.

[0026] In practical use, it is necessary to be able to directly observe the water sample condition and quantity during the sampling process. In order to meet the above requirements, in this embodiment, the side wall of the sampling bucket 1 is made of transparent material.

[0027] In practical use, it is necessary to effectively prevent moisture and humidity from entering the device and protect electronic components and mechanical parts from damage. In order to meet the above requirements, in this embodiment, the protective box 9 is made of waterproof material.

[0028] In practical use, it needs to be able to resist the corrosion and abrasion of water. In order to meet the above requirements, in this embodiment, the water suction head 7 is made of corrosion-resistant and wear-resistant material.
