A main control device connected to the sensor probe 2 is provided in the equipment body 1, and the main control device realizes monitoring and data transmission functions. This technology is relatively mature and will not be described in detail here. At the same time, a power supply for power supply is provided inside the equipment body 1, and the water and electricity of the equipment are separated to avoid water ingress into the equipment and damage to the equipment;

[0025] The sampling mechanism includes a connecting piece fixedly connected to the outside of the device body 1, such as Figure 1 As shown, the connecting piece includes two relatively arranged connecting blocks 5, and a sampling bottle 6 is connected between the corresponding two connecting blocks 5.

In order to facilitate pumping, an air outlet can be provided on the side wall of the sampling bottle 6, so that when water is pumped into the sampling bottle 6, the gas inside the sampling bottle 6 is discharged under pressure;

[0026] Specifically, if Figure 3 As shown, the annular filter screen 4 includes an annular plate 401, the side wall of which is penetrated by a plurality of annularly distributed through grooves 402. The outer peripheral surface of the annular plate 401 is fixedly connected to the filter screen, which is flexibly attached to the outer side of the annular plate 401. The annular plate 401 serves as a skeleton support.

[0027] Specifically, if Figure 4 As shown, the connecting plates 3 are fixed by a rod 8 to connect the two connecting plates 3 into a whole. The surface of the connecting plate 3 is fixedly connected to a limit plate 9 sleeved on the outside of the annular filter 4, so that the annular filter 4 is fixed between the two connecting plates 3;

[0028] Specifically, if Figure 4 As shown, the end face of the limiting plate 9 is provided with a notch, and a cleaning brush 19 that fits with the filter screen is provided at the corresponding notch between the connecting plates 3. Since the annular filter screen 4 is arranged between the connecting plates 3 through the limiting plate 9, the annular filter screen 4 can rotate between the connecting plates 3. The inner circumferential surfaces of the upper and lower ends of the annular plate 401 are respectively fixedly connected with internal gears 10. The surface of the connecting plate 3 is provided with a gear 11 that meshes with the internal gear 10. The gear 11 can be rotated by the driving gear 11. Under the action of the internal gear 10, the annular plate 401 is driven to rotate between the connecting plates 3, and the cleaning brush 19 is provided on the outside of the annular filter screen 4 to clean the surface of the annular filter screen 4 to prevent debris from clogging the filter screen and affecting the operation of the sensor probe 2. A driving motor (not specifically shown in the figure) for driving the gear 11 to rotate can be provided inside the device body 1.

[0029] Specifically, if Figure 5As shown, a cavity 12 is provided inside the connecting plate 3, and a slide groove 13 is provided on the surface of the connecting plate 3, which is connected to the cavity 12 and extends along the radial direction of the annular plate 401.

An elastic element is provided between the slider 14 and the corresponding slide groove 13. Under the action of the elastic element, the slider 14 drives the cleaning brush 19 to move toward the annular filter 4, so that the cleaning brush 19 is close to the surface of the annular filter 4. The two ends of the cleaning brush 19 are coaxially connected to the first transmission roller 15 inside the cavity 12, and the gear 11 is coaxially connected to the second transmission roller 16 that cooperates with the first transmission roller 15. A transmission belt is provided between the first transmission roller 15 and the second transmission roller 16. When the internal gear 10 is driven to rotate by the gear 11, the cleaning brush 19 is driven to rotate synchronously under the action of the first transmission roller 15 and the second transmission roller 16 to clean the annular filter 4.

[0030] Specifically, a sealing plug 17 is movably provided at the mouth of the sampling bottle 6, and a push rod 18 is fixedly connected inside the connecting tube 7 for lifting the sealing plug 17 to connect the connecting tube 7 to the sampling bottle 6.

The top end of the sampling bottle 6 is inserted into the groove of the upper end connecting block 5. After the sampling bottle 6 is taken out, the elastic member causes the sealing plug 17 to seal the bottle mouth of the sampling bottle 6, so that the sample remains inside the sampling bottle 6.

[0031] When the present invention is used, the device body 1 is set inside the water body to be monitored, and the water quality of the water body is monitored by the sensor probe 2. After the device has been used for a period of time, the gear 11 can be controlled to rotate, and the gear 11 drives the internal gear 10 to rotate, that is, drives the annular filter 4 to rotate. At the same time, the cleaning brush 19 is driven to rotate under the action of the first transmission roller 15 and the second transmission roller 16 to clean the surface of the annular filter 4. By starting the pump body and the valve, water is pumped into the sampling bottle 6 for sampling.
