DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] Embodiment one

[0034] Please refer to Figures 1-8 A water quality monitoring device based on unmanned aerial vehicle, comprising an unmanned aerial vehicle main body 1, further comprising a shell 2, a monitoring component, a fixed rod 7, a depth monitoring component and a sampling cylinder 6.

[0035] In the present application, the unmanned aerial vehicle main body 1 is an existing product, which is a remote controller. The shell 2 is detachably installed at the bottom end of the unmanned aerial vehicle main body 1. Therefore, a winding component is arranged in the shell 2. A pull rope 5 is wound on the winding component. One end of the pull rope 5 penetrates to the outside of the shell 2. The winding of the pull rope 5 can be controlled by the winding component and released, so as to adjust the depth. The fixed rod 7 is fixedly installed at the bottom end of the pull rope 5. The sampling cylinder 6 is detachably installed at the outside of the fixed rod 7, which is used for sampling water. The mounting bracket 18 is fixedly installed at the outside of the sampling cylinder 6. The mounting bracket 18 is fixedly connected with the fixed rod 7 by bolts. The fixed shell 24 is fixedly installed at the outside of the mounting bracket 18.

[0036] Among them,

[0037] Further description, the winding component comprises a motor fixedly installed in the shell 2 and a winding disc fixedly installed on the driving shaft of the motor. The pull rope 5 is wound on the winding disc. Therefore, the rotation of the winding disc can be controlled by the motor. Thus, the release and winding of the pull rope 5 can be realized, so as to control the lifting. In the art, the rotation of the winding disc controlled by the motor is also an existing technology. The motor is preferably a self-locking motor.

[0038] Among them,

[0039] The monitoring component is arranged outside the shell 2 for monitoring the water quality, and the monitoring component comprises a monitoring unit 25 and a third controller 23. The detection box 3 is fixedly installed outside the shell 2, the monitoring unit 25 is arranged in the detection box 3, and the third controller 23 is fixedly installed outside the shell 2. A display screen is also fixedly installed outside the shell 2. The monitoring unit 25 is used for monitoring the water liquid, and the display screen and the monitoring unit 25 are electrically coupled with the third controller 23;

[0040] The water liquid after sampling is mainly poured into the detection box 3, and then the water quality is monitored by the monitoring unit 25, and then the result is displayed on the display screen;

[0041] Therefore, it should be noted that the monitoring unit 25 comprises a residual chlorine sensor, a conductivity sensor, a pH sensor, an ORP sensor and a turbidity sensor;

[0042] It should be noted that the residual chlorine sensor, the conductivity sensor, the pH sensor, the ORP sensor and the turbidity sensor are all existing products in the field of water quality monitoring sampling, and any model can be purchased on the market. Therefore, the model is not limited in this article, and the residual chlorine content, conductivity or overall ion concentration of the water sample, pH, oxidation-reduction potential and water turbidity of the water liquid are monitored by the residual chlorine sensor, the conductivity sensor, the pH sensor, the ORP sensor and the turbidity sensor.

[0043] It should be noted that,

[0044] The depth monitoring component is arranged outside the fixed rod 7 for monitoring the depth of the fixed rod 7.

[0045] The depth monitoring component comprises a waterproof box 13 fixedly installed outside the fixed rod 7, a second controller 22 fixedly installed in the waterproof box 13, a touch panel 14 fixedly installed outside the waterproof box 13 and a water pressure sensor 19 fixedly installed at the bottom end of the fixed rod 7.

[0046] The water pressure sensor 19 and the touch panel 14 are electrically coupled with the second controller 22. In order to increase the waterproof performance, the touch panel 14 can be covered with a waterproof film. The touch panel 14 can be a touch display screen. The touch panel 14 is mainly used to set the depth of the lowering. The water pressure sensor 19 is an existing product, such as a CS456 pressure type water level sensor. In order to control the motor, the motor is also electrically coupled with the second controller 22.

[0047] And the technical principle is as follows: the second controller 22 is back to P = rho gh, h = P / rho g, and h represents the depth, P represents the water pressure strength, that is, the value measured by the water pressure sensor 19, and rho is the density of water = 1 x 10^3 kg / m^3, and g represents the gravity acceleration, which is 9.8 N / kg;

[0048] So you can get the depth by h = P / rho g.

[0049] In order to automatically start sampling;

[0050] So the electromagnetic valve 9 is fixedly installed at the bottom end of the sampling cylinder 6, the first controller 21 is fixedly installed in the fixed shell 24, the second weighing sensor 17 is fixedly installed at the top end of the fixed shell 24, the connecting rod 12 is rotatably installed outside the fixed block 10, the waterproof motor 11 is also fixedly installed outside the fixed block 10, the driving shaft of the waterproof motor 11 is fixedly connected with the connecting rod 12, and the waterproof motor 11 is used to drive the connecting rod 12 to rotate.

[0051] Among them, one end of the connecting rod 12 is fixedly installed with a rubber sleeve 15, and the first weighing sensor 16 is fixedly installed in the rubber sleeve 15, and the first weighing sensor 16 and the second weighing sensor 17 are both waterproof weighing sensors, such as the weighing sensor with model S40AC3 / 500Kg. By the mutual collision between the first weighing sensor 16 and the second weighing sensor 17, a weight signal value can be generated, so the waterproof motor 11 is electrically connected with the second controller 22, the first weighing sensor 16 is electrically coupled with the second controller 22, and the second weighing sensor 17 and the electromagnetic valve 9 are electrically coupled with the first controller 21.

[0052] The technical principle is as follows: once the fixed rod 7 drives the sampling cylinder 6 to reach the set value, the second controller 22 automatically closes the motor and stops working, and then the second controller 22 starts the waterproof motor 11 to work, the waterproof motor 11 drives the connecting rod 12 to rotate, and the connecting rod 12 rotates towards the fixed shell 24, so that the first weighing sensor 16 and the second weighing sensor 17 can detect the weighing value by rubbing each other through the rubber sleeve 15; therefore, when the second weighing sensor 17 transmits the value to the first controller 21, the first controller 21 judges that the sampling cylinder 6 reaches the set position, and then opens the electromagnetic valve 9 for a period of time, so that the water enters the sampling cylinder 6 through the electromagnetic valve 9, thereby achieving the benefit of automatic sampling.

[0053] Need to be particularly pointed out, the power used in this application, all in the waterproof box 13 and fixed shell 24 are equipped with lithium batteries installed for power supply, and the first controller 21, the second controller 22 and the third controller 23 are programmable controllers, which can be purchased on the market, such as programmable controller with model S7-200.

[0054] With reference to the following operation:

[0055] The sampling cylinder 6 is detachably mounted on the fixed rod 7 through the mounting frame 18, and then the depth required to be lowered is set through the operation of the touch panel 14, such as 2 m, and then the unmanned aerial vehicle body 1 drives the sampling cylinder 6 to fly over the sampling area of the lake;

[0056] When reaching the appropriate position, the remote control motor works, and the motor drives the winding disc to rotate, so that the winding disc releases the rope 5, so that the fixed rod 7 drives the sampling cylinder 6 to fall into the water surface;

[0057] At the same time, the water pressure sensor 19 can detect the real-time water pressure, and then transmit the water pressure signal to the second controller 22;

[0058] The second controller 22 is obtained by: P = ρgh, h = P / ρg, and h represents the depth, P represents the water pressure strength, that is, the value measured by the water pressure sensor 19, and ρ is the density of water = 1 × 10^3 kg / m^3, and g represents the gravitational acceleration, which is 9.8 N / kg;

[0059] Therefore, h = P / ρg can be obtained, and the depth reached is obtained;

[0060] Once the depth of the fixed rod 7 driving the sampling cylinder 6 reaches the set value, that is, h = 2 m, so the second controller 22 automatically closes the motor and stops working, and then the second controller 22 starts the waterproof motor 11 to work, and the waterproof motor 11 drives the connecting rod 12 to rotate, so that the connecting rod 12 rotates towards the fixed shell 24, so that the first weighing sensor 16 and the second weighing sensor 17 can detect the weighing value through the rubber sleeve 15;

[0061] Therefore, when the second weighing sensor 17 transmits the value to the first controller 21, the first controller 21 judges that the sampling cylinder 6 reaches the set position, and then opens the electromagnetic valve 9 for a period of time, such as 30 s, so that the water enters the sampling cylinder 6 through the electromagnetic valve 9, and then the first controller 21 automatically closes the electromagnetic valve 9, and finally, the unmanned aerial vehicle flies back;

[0062] Then the water liquid in the sampling cylinder 6 is taken out and poured into the detection box 3, and the water quality is monitored by the residual chlorine sensor, the conductivity sensor, the PH sensor, the ORP sensor and the turbidity sensor in the monitoring unit 25.

[0063] Therefore, the water liquid can be sampled and monitored in time.

[0064] Embodiment two

[0065] As a preferred scheme of the embodiment one, the counterweight 20 is detachably installed outside the mounting frame 18.

[0066] The counterweight 20 is detachably installed with the mounting frame 18 through bolts.

[0067] The purpose of the counterweight 20 is to make the weight of the two ends of the fixing rod 7 not much different, so that the fixing block 10 can vertically enter the water surface.

[0068] Embodiment three

[0069] As a preferred scheme of the embodiment one or the embodiment two, a plurality of groups of the cylinder are arranged, and two adjacent sampling cylinders 6 are detachably fixed and installed through the connecting rod 8. The connecting rod 8 is detachably installed through the installation and cooperation of the bolts.

[0070] Through the arrangement of the plurality of groups of the sampling cylinders 6, different water depth sampling and monitoring can be facilitated.
