Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0029] Reference Figures 1-7A water sampling bottle self-replacing device includes an unmanned aerial vehicle (UAV) 1. An extension arm is mounted on the top of the UAV 1, with a rotor at the distal end of the extension arm. A support is fixed to the bottom of the UAV 1, and a float is located at the bottom of the support to assist the UAV 1 in floating on the water surface. A sampling device body 2 is fixed to the bottom of the UAV 1. A sampling bottle 207 is located on the inner wall of the sampling device body 2. A sampling pump 201 is fixed to the surface of the sampling device body 2. A water sampling pipe 202 is fixed to one end of the sampling pump 201, and a water inlet pipe 203 is fixed to the other end of the sampling pump 201. A solenoid valve 209 is located at one end of the water inlet pipe 203. A bottom rotating disc 2 is rotatably connected to the inner wall of the sampling device body 2. 04. The bottom rotating disk 204 is driven by the drive motor 205. The top of the bottom rotating disk 204 is provided with multiple sampling bottles 207. The circumference of the sampling bottle 207 is provided with a side groove 208. The inner wall of the side groove 208 is provided with an electromagnetic valve body 209. The sampling bottle 207 is connected to the water inlet pipe 203 through the electromagnetic valve body 209. By setting multiple sampling bottles 207 connected to the water inlet pipe 203 through the electromagnetic valve body 209 in the main body of the sampling device 2, and the position of the sampling bottle 207 in the main body of the sampling device 2 can be changed by rotating the bottom rotating disk 204, the unmanned aerial vehicle 1 can perform multiple samplings in a single flight, realize continuous water quality sampling, and reduce sampling costs.
[0030] The solenoid valve body 209 uses the domestically produced ZQDF-Y-25 model solenoid valve, which is a step-by-step direct-acting type with a stainless steel valve body that is corrosion-resistant and suitable for liquid media. It facilitates the quick fixing and separation between the sampling bottle body 207 and the water inlet pipe 203. The sampling bottle body 207 is a PULL series stainless steel sampling bottle, which is well compatible with the ZQDF-Y-25 solenoid valve.
[0031] A base plate 4 is fixed to the bottom of the sampling device body 2, and a mounting column 206 is fixed to the top of the inner wall of the sampling device body 2. The mounting column 206 is a hollow column with heat dissipation grooves on its circumference. A drive motor 205 is fixed to the bottom of the mounting column 206, and a bottom rotating disk 204 is fixed to the output end of the drive motor 205. The circumference of the bottom rotating disk 204 is rotatably connected to the inner wall of the base plate 4. The drive motor 205 is fixed to the top of the inner wall of the sampling device body 2 via the mounting column 206, which facilitates its driving of the bottom rotating disk 204. At the same time, the hollow column and heat dissipation grooves of the mounting column 206 facilitate heat dissipation of the drive motor 205.
[0032] A limiting groove 303 is formed at the top of the inner wall of the sampling device body 2. A limiting ring 302 is slidably connected to the inner wall of the limiting groove 303. A top limiting plate 3 is fixed on the inner circumferential surface of the limiting ring 302. Multiple top locking slots 301 are formed in a circular array at the bottom of the top limiting plate 3. The inner wall of the top locking slot 301 is in contact with the top of the sampling bottle 207. By setting the top limiting plate 3 and making the top of the sampling bottle 207 in contact with the top locking slots 301 at the bottom of the top limiting plate 3, the stability of the sampling bottle 207 in the sampling device body 2 is increased. In some dynamic water areas, the sampling bottle 207 is prevented from being shaken and tipped over. Moreover, the top limiting plate 3 can change position with the sampling bottle 207, reducing the impact on the rotation of the bottom rotating plate 204.
[0033] Multiple mounting plates 403 are fixed to the bottom of the base plate 4. The mounting plates 403 are fixed to the bottom of the sampling device body 2 by bolts. A limiting ring groove 401 is opened on the inner circumferential surface of the base plate 4. A limiting ring plate 405 is slidably connected to the inner wall of the limiting ring groove 401. The inner circumferential surface of the limiting ring plate 405 is fixed to the circumferential surface of the bottom rotating plate 204. The base plate 4 is fixed to the bottom of the sampling device body 2 by the mounting plates 403, which makes it convenient for staff to disassemble and assemble the sampling bottle 207.
[0034] The bottom of the inner wall of the base plate 4 is provided with a wheel groove 404, and the bottom of the bottom rotating disk 204 is rotatably connected with an auxiliary wheel 402. The auxiliary wheel 402 reduces the friction between the bottom of the bottom rotating disk 204 and the bottom of the inner wall of the base plate 4, and prevents significant wear caused by the large weight of the sampling bottle 207 after sampling.
[0035] The top of the bottom rotating disk 204 has a circular array of multiple bottom grooves 6. The bottom of the sampling bottle 207 fits against the inner wall of the bottom groove 6. The bottom of the sampling bottle 207 has an elliptical groove 5. The bottom of the inner wall of the bottom groove 6 is fixed with a bottom limiting member 7. The surface of the bottom limiting member 7 is nested with the inner wall of the elliptical groove 5. The top of the inner wall of the bottom groove 6 is provided with a groove top arc surface 8. The inner wall of the bottom groove 6 is fixed with a bottom-embedded ring member 803. The bottom edge of the sampling bottle 207 is set as a bottle bottom arc surface 801. The bottom end of the sampling bottle 207 has a bottom-embedded groove 802. By setting the elliptical groove 5, the bottom groove 6 and the bottom limiting member 7, the position of the sampling bottle 207 on the bottom rotating disk 204 is restricted. At the same time, the bottom-embedded ring member 803 and the bottom-embedded groove 802 are used to fasten and fix the sampling bottle 207, preventing the sampling bottle 207 from tipping over when the UAV 1 is flying or when sampling in water, and further improving the stability of the sampling bottle 207.
[0036] The working principle of this utility model is as follows: When it is necessary to sample the water quality, the staff removes the bolts from the bottom mounting plate 403 of the sampling device body 2, separating the bottom plate 4 from the sampling device body 2. A suitable number of sampling bottles 207 are selected according to the actual situation. The bottom of the sampling bottle 207 is aligned with the bottom groove 6 of the bottom rotating plate 204 and pressed down. The bottom arc surface 801 of the bottle contacts the top arc surface 8 of the groove, causing elastic deformation. The bottom ring 803 is inserted into the bottom groove 802, fixing the sampling bottle 207 to the bottom rotating plate 204. Then, the bottom plate 4 is re-bolted to the sampling device body 2. The top of the sampling bottle 207 fits against the top locking groove 301 at the bottom of the top limiting plate 3, restricting the position of the sampling bottle 207 and preventing it from tipping over during the flight of the unmanned aerial vehicle 1 or when sampling in the water area. The staff then controls the unmanned aerial vehicle 1 to fly to the sampling area and floats on the water surface using the floatation tank. The drive motor 205 is started, causing the bottom rotating plate 204 to rotate. Align the side groove 208 of the sampling bottle 207 with the water inlet pipe 203. Activate the solenoid valve 209 to connect the water inlet pipe 203 with the sampling bottle 207. Then, the sampling pump 201 starts, and water flows in through the water collection pipe 202 and out through the water inlet pipe 203 into the sampling bottle 207. When the sampling volume of the sampling bottle 207 is sufficient, the solenoid valve 209 disconnects, and the drive motor 205 continues to rotate the bottom disc 204 to align the side groove 208 of the next sampling bottle 207 with the water inlet pipe 203. Repeat this process to achieve multiple samplings of the water area. The auxiliary wheel 402 reduces the friction between the bottom of the bottom disc 204 and the bottom of the inner wall of the base plate 4, preventing significant wear caused by the large weight of the sampling bottle 207 after sampling. After the staff has completed sampling, the unmanned aerial vehicle 1 can be controlled to fly back, and the bolts of the mounting plate 403 can be removed to separate the base plate 4 from the main body 2 of the sampling device, and the sampling bottle 207 can be taken out.
