[0003] In order to solve the above problems, a Chinese patent (patent publication number: CN108088976B) discloses a groundwater monitoring system, including a control terminal and a power supply device for data acquisition and sampling control located in an external workstation of a monitoring well, a monitoring sensor group located in the monitoring well, a transmission line connecting the monitoring sensor group and the control terminal, and a monitoring device vertically installed in the monitoring well, wherein the monitoring device is composed of a plurality of partition plate groups arranged at intervals in a monitoring pipe, two adjacent partition plate groups obtain a sampling space in the monitoring pipe, and a pump is used to obtain water samples in the sampling space to realize groundwater detection; however, the monitoring device of the system is not easy to control the adjustment of the sampling depth, and the interval between the sampling spaces cannot be adjusted, which is inconvenient for application in different groundwater environments; therefore, a groundwater monitoring system is needed in which a monitoring device can adjust the sampling depth and sampling interval according to the groundwater environment. Summary of the invention

[0007] The principle of the basic technical solution: the power supply device provides electrical energy to the data processing terminal and the electrical components of the monitoring sampling device. The monitoring sampling device is placed inside the monitoring well to collect groundwater data and groundwater. When the monitoring sampling device enters the groundwater in the monitoring well, the first floating rod and the second floating rod are equivalent to the "float" of the monitoring sampling device. The first floating rod and the second floating rod provide an upward buoyancy to the entire monitoring sampling device. The first floating rod is rotatably connected to the fixed connecting rod and the second floating rod, and the second floating rod is rotatably connected to the sliding connecting rod. The sliding connecting rod is sleeved with the connecting rod, and the connection between the sliding connecting rod and the connecting rod is adjusted by sliding up and down.

The buoyancy of the first and second floating rods can be adjusted by adjusting the position of the sliding connecting rod and the connecting rod sleeve, so as to control the depth of the monitoring sampling device entering the groundwater surface. The adjustment is convenient, fast and effective. The depth of the monitoring sampling assembly sinking into the water surface can be adjusted according to different groundwater environments, and the application range is wide;

[0010] 2.

[0017] Preferably, the first floating rod, the second floating rod and the sliding connecting rod each have multiple pieces, and the multiple pieces of the first floating rod, the second floating rod and the sliding connecting rod are evenly arranged around the connecting rod, and the outer sides of the multiple pieces of the sliding connecting rods are sleeved with clamps, and the multiple pieces of the sliding connecting rods are sleeved with the connecting rod through the clamps.

[0018] Through the above arrangement, multiple first float rods and second float rods are evenly arranged around the connecting rod, so that the "float" formed by the multiple first float rods and the multiple second float rods has a uniform shape, so that the buoyancy of the monitoring and sampling device is uniform, which is beneficial to ensure the verticality of the monitoring and sampling device and further improve the accuracy of the monitoring data.

[0019] Preferably, an industrial airbag is connected to the chamber formed by the plurality of first floating rods and the second floating rods.

[0020] Through the above arrangement, the buoyancy of the "float" can be adjusted by inflating and deflating the industrial air bag. That is, when the monitoring and sampling device is inside the monitoring well, the depth of the monitoring and sampling device submerged in the liquid surface can be adjusted by inflating and deflating the industrial air bag. The adjustment is convenient and quick.

[0021] Preferably, the connecting pipe is also connected to an electric paddle, the electric paddle is electrically connected to the power supply device, and the electric paddle is arranged at the lower end of the monitoring sampling assembly.

[0022] Through the above-mentioned setting, starting the electric paddle can not only improve the buoyancy of the monitoring and sampling device, but also disperse the mayflies around the monitoring and sampling device.

[0023] Preferably, the electrical connection between the multiple monitoring and sampling components is in parallel, and the return pipe and the electrical conductor are arranged in the hollow of the connecting pipe.

[0024] Through the above-mentioned arrangement, multiple monitoring and sampling components are connected in parallel, making them independent of each other, which can effectively avoid the entire device being unusable due to damage to one monitoring and sampling component; the return pipe and the electrical conductor are arranged in the hollow of the connecting pipe, which is beneficial to improving the neatness of the entire device and avoiding the influence of mutual entanglement.
