[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-3 A sampling device for detecting water use in an agricultural environment includes a sampling tank 1. The sampling tank 1 is made of a transparent material and is provided with a sampling structure 3. The sampling structure 3 includes a partition 310 installed on the inner wall of the sampling tank 1. The sampling tank 1 is divided into two upper and lower areas by the partition 310. The upper area is filled with samples on the water surface, and the lower area is filled with samples on the bottom of the water.

[0028] A second float 311 is placed on the top wall of the partition 310, and a water inlet is opened on the top wall of the sampling tank 1. When water enters the upper area of ​​the sampling tank 1, the second float 311 is lifted up and connected with the water inlet of the sampling tank 1, effectively preventing water from flowing out of the sampling tank 1.

[0029] A base 304 is installed on the bottom wall of the sampling tank 1, and a water inlet is opened at the center position of the base 304. An electric telescopic rod 305 is installed on the inner wall of the base 304. There are four electric telescopic rods 305, which are evenly distributed around the circumference of the base 304. A rubber block 306 is installed at the telescopic end of each electric telescopic rod 305. The four rubber blocks 306 are blocked from the water inlet of the base 304 by the electric telescopic rod 305, thereby effectively improving the sealing performance of the sampling tank 1.

[0030] A first float 309 is placed on the top wall of the rubber block 306. A second sensor 312 is installed at one end of the partition 310 away from the second float 311. The model of the second sensor 312 is PUR-CY13. The second sensor 312 and the first float 309 are in the same vertical plane. The second sensor 312 is electrically connected to the electric telescopic rod 305. A first sensor 303 is arranged at the bottom of the sampling tank 1. The model of the first sensor 303 is PUR-CY13. It is electrically connected to the electric telescopic rod 305. By starting the electric telescopic rod 305 to open the rubber block 306, water enters the lower area of ​​the sampling tank 1 from the water inlet of the base 304. At this time, the first float 309 is driven to float and touch the second sensor 312. The staff receives the signal through the second sensor 312 and pulls up the device. At the same time, the electric telescopic rod 305 is controlled by the second sensor 312 to make the rubber block 306 block the water inlet of the base 304, thereby achieving a certain sealing effect.

[0031] A slider 307 is installed on the outer wall of the rubber block 306, and a slide groove 308 is provided on the side of the rubber block 306 away from the slider 307. A slider 307 is installed on the left side of each rubber block 306, and the other slide groove 308 is provided for inserting the slider 307. By using the electric telescopic rod 305, the four rubber blocks 306 are connected together through the slider 307 and the opened slide groove 308, thereby further strengthening the sealing of the water inlet of the base 304.

[0032] Reference Figure 1 and Figure 4 A fixing structure 2 is provided on the sampling tank 1, and the fixing structure 2 includes a bottom plate 206 attached to the bottom wall of the sampling tank 1, and a first connecting piece 201 is installed on the outer wall of the bottom plate 206. The number of the first connecting pieces 201 is three, and they are equidistantly distributed around the circumference of the bottom plate 206. A sliding column 202 is installed on the inner wall of each first connecting piece 201, and a second connecting piece 203 is slidably connected to the top wall of each sliding column 202. A top plate 204 is installed on the outer wall of the second connecting piece 203, and the bottom wall of the top plate 204 is tightly attached to the top wall of the sampling tank 1. The top plate 204 is connected to the sampling tank 1, which not only fixes the sampling tank 1, but also increases the weight of the sampling tank 1 so that it can sink faster, and also provides a certain protective effect on the sampling tank 1.

[0033] One end of each sliding column 202 away from the first connecting member 201 is threadedly connected to a threaded handle 205, and the outer wall of the threaded handle 205 is in contact with the top wall of the second connecting member 203. The threaded handle 205 is arranged to facilitate the installation and disassembly of the fuel pump.

[0034] A support rod 301 is installed on the bottom wall of the bottom plate 206. There are three support rods 301, which are evenly distributed around the circumference of the bottom plate 206. A circular plate 302 is installed on the bottom wall of the support rod 301. The bottom wall of the first sensor 303 is fixedly connected to the top wall of the first sensor 303. The circular plate 302 is provided to facilitate the installation of the first sensor 303 without affecting the inflow of water from the water inlet of the base 304.

[0035] The outer wall of the sampling tank 1 is connected to a first drain pipe 4, which is located above the partition 310. The outer wall of the sampling tank 1 is connected to a second drain pipe 5, which is located below the partition 310. The first drain pipe 4 and the second drain pipe 5 are both provided with sealing gaskets to facilitate a certain sealing of the sampling tank 1. The first drain pipe 4 and the second drain pipe 5 are at a certain slope to facilitate the water in the sampling tank 1 to flow out of the sampling tank 1.

[0036] Working principle:

[0037] After placing the sampling tank 1 on the bottom plate 206, align the second connecting piece 203 with the sliding column 202 so that it fits with the top wall of the sampling tank 1, and then screw the threaded handle 205 onto the sliding column 202. This not only fixes the sampling tank 1, but also increases the weight of the sampling tank 1 so that it can sink faster, and also provides a certain degree of protection for the sampling tank 1.

[0038] The device is placed in water, and water flows into the upper area of ​​the sampling tank 1 through the water inlet at the top of the sampling tank 1. At this time, as the water flows in, the second buoy 311 floats up and blocks the water inlet of the sampling tank 1. At this time, the device continues to be lowered until the first sensor 303 touches the bottom of the water, and then a signal is transmitted to the electric telescopic rod 305. The telescopic end of the electric telescopic rod 305 drives the rubber block 306 to retract backward to open the water inlet of the base 304, and the water flows into the lower area of ​​the sampling tank 1. At this time, the first buoy 309 floats up with the water and touches the second sensor 312. The second sensor 312 simultaneously transmits signals to the shore and the electric telescopic rod 305, reminding the staff that they can pull it up, and the electric telescopic rod 305 drives the rubber block 306 to close and seal the water inlet of the base 304. Through the set sampling structure 3, the effect of sampling at the same time and position is effectively achieved, which effectively improves the understanding of the water situation at that moment, thereby effectively improving the accuracy and reliability of the data.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
