Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 6As shown, a water sample filtering mechanism for water quality monitoring includes an upper filtering mechanism and a lower filtering mechanism, the upper filtering mechanism is connected to the water sample taking mechanism, the lower filtering mechanism includes a turntable 204, a separation rod group 205 is fixedly connected with the bottom of the turntable 204 by thread, a cleaning mechanism is arranged on the separation rod group 205, the cleaning mechanism includes a cleaning scraper 306 slidably connected to the separation rod group 205, a plurality of through holes corresponding to the position of the separation rod group 205 are arranged on the cleaning scraper 306, a lifting frame 305 is rotatably connected to the outer side of the cleaning scraper 306, two studs 304 are symmetrically arranged on both sides of the turntable 204, the two studs 304 are threadedly connected to the lifting frame 305, a driving gear 301 is fixedly connected to the top of the turntable 204, two symmetrically arranged driven gears 302 are meshed on both sides of the driving gear 301, the driven gear 302 is connected to the stud 304 by a torque overload protection component, after the water sampling is completed, some water should still remain in the water taking device, in order to avoid mixing of the water sample for the next sampling , the residual water sample should be discharged, and the discharged water passes through the upper filtering mechanism, driving the turbine 106 to reverse, the turbine 106 drives the rotating shaft 105 to reverse, the rotating shaft 105 drives the transmission shaft 203 to reverse, the transmission shaft 203 drives the rotating disk 204 to reverse, the rotating disk 204 drives the driving gear 301 to rotate, and the driving gear 301 drives the driven gear 302 to rotate. At this time, since the friction plate 308 is in friction contact with the driven gear 302 and the torque transmitted to the supporting box 303 by the driven gear 302 is less than the set value, the driven gear 302 can drive the stud 304 to rotate, the stud 304 drives the lifting frame 305 to descend, and the lifting frame 305 drives the cleaning scraper 306 to descend. The cleaning scraper 306 scrapes away impurities such as water plants or plastic bags wrapped around the separation rod group 205, so that the cleaning work can be completed. When the cleaning scraper 306 reaches the lowering limit, the driven gear 302 and the friction plate 308 slide relative to each other, so that the driven gear 302 cannot drive the stud 304 to rotate.

[0027] The upper filtering mechanism includes an upper filtering chamber 101, the top of the upper filtering chamber 101 is fixedly and sealedly connected to the water intake suction head of the water sampling device in the prior art, and the top of the upper filtering chamber 101 is threadedly and sealedly connected to the top cover 102.

[0028] A rotating shaft 105 is rotatably connected to the lower bracket 103, and the rotating shaft 105 passes through the bottom of the filter cartridge 104. A turbine 106 is fixedly connected to the top of the rotating shaft 105, and a transmission shaft 203 is fixedly connected to the bottom of the rotating shaft 105. One end of the transmission shaft 203 is rotatably connected to the lower bracket 103, and the other end of the transmission shaft 203 is fixedly connected to the turntable 204.

The rotating separation rod group 205 can enhance the separation effect of the separation rod group 205.

[0029] The lower filtering mechanism also includes a lower filtering chamber 201 which is sealed and fixedly connected to the upper filtering chamber 101 through a flange.

A water-permeable hole is provided in the middle of the cleaning scraper 306. Water in the external water area enters the lower filtering chamber 201 from the water inlet 202. The rotating separation rod group 205 removes impurities such as aquatic plants or plastic bags in the water. The water that has been filtered once enters the upper filtering chamber 101 from the top of the lower filtering chamber 201.

[0030] The torque overload protection component includes a support box 303 rotatably connected to the driven gear 302, the support box 303 is fixedly connected to the stud 304, a friction plate 308 is slidably connected inside the support box 303, the friction plate 308 is in contact with the driven gear 302, a spring 307 is fixedly connected between the friction plate 308 and the driven gear 302, under the support of the spring 307, there is friction between the friction plate 308 and the driven gear 302, so that the driven gear 302 can transmit power to the support box 303 through friction, the support box 303 can drive the stud 304 to rotate, after the cleaning scraper 306 moves to the top limit position or the bottom limit position, it cannot move, and the stud 304 cannot rotate, at this time, the torque between the driven gear 302 and the friction plate 308 exceeds the friction, and relative sliding occurs between the driven gear 302 and the friction plate 308, at this time, the release rod group 205 rotates normally but the lifting frame 305 does not produce displacement.

[0031] Working principle: the water pump of the water sampling device in the prior art is started to draw water in the target water area into the lower filtering mechanism, and the water in the external water area enters the lower filtering chamber 201 from the water inlet 202. The separation rod group 205 removes impurities such as aquatic plants or plastic bags in the water, and the water that has been filtered once enters the upper filtering chamber 101 from the top of the lower filtering chamber 201, and then enters the upper filtering mechanism after preliminary filtration by the lower filtering mechanism.

In order to avoid mixing of the water sample for the next sampling The residual water sample should be discharged, and the discharged water passes through the upper filtering mechanism, driving the turbine 106 to reverse, the turbine 106 drives the rotating shaft 105 to reverse, the rotating shaft 105 drives the transmission shaft 203 to reverse, the transmission shaft 203 drives the rotating disk 204 to reverse, the rotating disk 204 drives the driving gear 301 to rotate, and the driving gear 301 drives the driven gear 302 to rotate. At this time, since the friction plate 308 is in friction contact with the driven gear 302 and the torque transmitted from the driven gear 302 to the support box 303 is small When the cleaning scraper 306 reaches the lower limit, the driven gear 302 and the friction plate 308 slide relative to each other, so that the driven gear 302 cannot drive the stud 304 to rotate.
