Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to a drone-based water quality monitoring device. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types, concentrations, and trends of pollutants in water bodies to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various industrial wastewater. Traditional water quality monitoring requires boat sampling, which is inefficient. Nowadays, using drones for sampling has increased efficiency several times over. Drone water quality monitoring devices are intelligent monitoring systems that combine water quality sensors with a drone platform. They are used to efficiently, flexibly, and over a wide area acquire water environmental parameters. They are gradually becoming an important supplement to traditional manual sampling and fixed monitoring stations. Common drone water quality monitoring devices typically use a drone platform paired with contact or non-contact water quality sensors for monitoring. Contact water quality sensors measure directly by immersing the water and are typically used for detecting pH, dissolved oxygen, conductivity / salinity, turbidity, temperature, redox potential, ammonia nitrogen, and nitrate. Non-contact water quality sensors analyze the spectral information of water reflection / radiation to retrieve parameters such as chlorophyll a, suspended solids concentration, colored soluble organic matter, transparency, and even certain pollutants (such as petroleum). While the above methods of monitoring water quality using sensors are fast and efficient, for some aspects of the water source, such as the complete analysis of heavy metals, organic pollutants, and nutrients, it is necessary to bring the water source back to the laboratory for more precise offline analysis. The above methods are inconvenient for collecting water sources. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0004] In view of the problems existing in the above and / or existing UAV water quality monitoring devices, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a water quality monitoring device for unmanned aerial vehicles (UAVs). When it is necessary to collect water from a source and bring it back to the laboratory for testing, the auxiliary frame is pushed by an electric telescopic rod, so that the extension tube moves and adjusts inside the suction tube, thereby indirectly lengthening the suction tube. The extension tube is then inserted into the water source. Under the action of the pump, the water source is input into the collection box through the extension tube, suction tube, and connecting tube, and then the collected water source is brought back to the laboratory for testing.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A drone-based water quality monitoring device includes a drone body. A placement slot is located at the center of the upper end of the drone body, and a collection box is placed within the placement slot. A through-slot is located at the center of the lower end of the drone body, and the through-slot is connected to the placement slot. A pump body is installed inside the through-slot. The outlet end of the pump body is connected to a collection pipe at the lower end of the collection box. The inlet end of the pump body is connected to a connecting pipe. The end of the connecting pipe away from the pump body is connected to a suction pipe. An extension pipe is inserted through the suction pipe. A connecting plate is fixedly inserted through the outer circumference of the extension pipe near its lower end. An auxiliary frame is fixedly connected to the right side of the connecting plate. A water quality sensor is fixedly inserted through the bottom of the auxiliary frame. An electric telescopic rod is fixedly connected to the upper end of the auxiliary frame.

[0009] As a preferred embodiment of the UAV water quality monitoring device described in this utility model, a fixed plate is fixedly installed near the bottom of the outer ring of the collection box. The fixed plate has through holes arranged in a ring array. A bolt is inserted through the through hole, and the lower end of the bolt is threaded into the bolt hole, which is located at the bottom of the mounting groove.

[0010] In a preferred embodiment of the UAV water quality monitoring device described in this utility model, a water intake port is provided at the upper end of the collection box, and a sealing cap is threaded onto the water intake port.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When it is necessary to collect water samples for laboratory testing, the auxiliary frame is pushed by the electric telescopic rod, which moves and adjusts the extension tube inside the suction tube, thereby indirectly lengthening the suction tube. The sealing ring between the sealing plug and the suction tube ensures the sealing performance of the extension tube after it moves and adjusts inside the suction tube. The extension tube is inserted into the water source, and under the action of the pump, the water source is input into the collection box through the extension tube, suction tube, and connecting pipe. The collected water source is then brought back to the laboratory for testing. When direct testing is performed without collecting water source samples, the auxiliary frame is pushed by the electric telescopic rod, which immerses the water quality sensor in the water for measurement.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] This utility model provides a water quality monitoring device for unmanned aerial vehicles (UAVs). When it is necessary to collect water from a source and bring it back to the laboratory for testing, the auxiliary frame is pushed by an electric telescopic rod, which causes the extension tube to move and adjust inside the suction tube, thereby indirectly lengthening the suction tube. The extension tube is then inserted into the water source. Under the action of the pump, the water source is input into the collection box through the extension tube, suction tube, and connecting tube, and then the collected water source is brought back to the laboratory for testing.

[0028] Figures 1-7 The diagram shown is an overall structural schematic of one embodiment of the UAV water quality monitoring device of this utility model. Please refer to [link / reference]. Figures 1-7 This embodiment of a drone water quality monitoring device includes a drone body 1. A placement groove 3 is provided at the center of the upper end of the drone body 1, and a collection box 4 is placed in the placement groove 3. A through groove 9 is provided at the center of the lower end of the drone body 1, and the through groove 9 is connected to the placement groove 3. A pump body 10 is provided inside the through groove 9. The outlet end of the pump body 10 is connected to the collection pipe at the lower end of the collection box 4. The inlet end of the pump body 10 is connected to the connecting pipe 11. The end of the connecting pipe 11 away from the pump body 10 is connected to the suction pipe 12. An extension pipe 13 is provided through the inside of the suction pipe 12. A connecting plate 15 is fixedly provided through the outer ring of the extension pipe 13 near the lower part. An auxiliary frame 16 is fixedly connected to the right side of the connecting plate 15. A water quality detection sensor 17 is fixedly provided through the bottom of the auxiliary frame 16. An electric telescopic rod 18 is fixedly connected to the upper end of the auxiliary frame 16.

[0029] The main body of the drone 1 is fixedly equipped with brackets 2 on both the left and right sides. The electric telescopic rod 18 is fixedly installed at the lower end of the mounting plate 19, which is fixedly installed on the right side wall of the through groove 9.

[0030] When direct detection is performed without collecting water, the auxiliary frame 16 is pushed by the electric telescopic rod 18 to immerse the water quality sensor 17 in the water for measurement. The water quality sensor 17 does not necessarily have to be immersed in the water for measurement; it depends on the actual monitoring requirements. The water quality sensor 17 can be a contact water quality sensor or a non-contact water quality sensor. When water needs to be collected and brought back for testing, the auxiliary frame 16 is pushed by the electric telescopic rod 18 to move and adjust the extension tube 13 within the suction tube 12, thereby indirectly lengthening the length of the suction tube 12 to facilitate water collection. The side of the extension tube 13 closest to the connecting plate 15 is inserted into the water source. Under the action of the pump body 10, the water source is input into the collection box 4 through the extension tube 13, suction tube 12, and connecting tube 11. The collected water source is then brought back to the laboratory for testing. The data transmission part during direct detection uses existing technology structures, usually utilizing the onboard data transmission radio of the UAV to transmit data, or existing methods such as local storage and post-event reading for testing. Among these, the hovering of the UAV body 1 during collection or testing is a common technology in UAVs and will not be described in detail in this patent.

[0031] A fixed plate 6 is fixedly installed near the bottom of the outer ring of the collection box 4. The fixed plate 6 has through holes 7 arranged in a ring array. A bolt 8 is inserted through the through hole 7. The lower end of the bolt 8 is threaded into the bolt hole. The bolt hole is located at the bottom of the placement groove 3. A water intake pipe is provided at the upper end of the collection box 4. A sealing cap 5 is threaded onto the water intake pipe.

[0032] The threaded opening of the sealing cover 5 is used to take out and test the water source collected in the collection box 4. The collection box 4 is threaded into the bolt hole through the through hole 7 on the fixing plate 6 by the bolt 8, thereby installing and fixing it in the placement groove 3.

[0033] A sealing plug 14 is fixedly installed on the outer ring of the extension tube 13 near the top, and a sealing ring is provided between the sealing plug 14 and the extraction tube 12.

[0034] A sealing ring is installed on the outer ring of the sealing plug 14 to enhance the seal between it and the drawing tube 12. Its working principle is similar to that of hydraulic cylinders and piston rods in the prior art.

[0035] The main body of the drone 1 includes a fixed adjustment frame 101 fixedly installed at the lower end of the drone body 1 near the front side. The inner wall of the fixed adjustment frame 101 is rotatably connected to a rotating shaft. The inner end of the rotating shaft is fixedly connected to a camera 102. The rotating shaft on one side passes through the fixed adjustment frame 101 and is connected to the output shaft of the motor 103.

[0036] The camera 102 captures images of the surroundings, allowing the operator to view the environment. This part is a prior art structure and is not a novel part of this patent application. The tilt angle of the camera 102 can be adjusted by the motor 103 and the rotating shaft to improve the monitoring range.

[0037] Combination Figures 1-7 The specific usage process of the UAV water quality monitoring device in this embodiment is as follows: When directly detecting without collecting water source, the auxiliary frame 16 is pushed by the electric telescopic rod 18 to adjust the water quality sensor 17 and then measure. The surrounding scene is collected by the camera 102, which is convenient for the operator to view the surrounding environment. The tilt angle of the camera 102 can be adjusted by the motor 103 and the rotating shaft to improve the monitoring range. When it is necessary to collect water source for testing, the auxiliary frame 16 is pushed by the electric telescopic rod 18 to move and adjust the extension tube 13 within the suction tube 12, thereby indirectly lengthening the length of the suction tube 12 to facilitate water source collection. The side of the extension tube 13 near the connecting plate 15 is inserted into the water source. Under the action of the pump body 10, the water source is input into the collection box 4 through the extension tube 13, suction tube 12, and connecting tube 11. The collected water source is then brought back to the laboratory for testing.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
