Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor are within the scope of protection of the present utility model.

[0021] Please refer to Figures 1-6 The present utility model provides a technical scheme: a multistage filtering device for water quality monitoring, which comprises a water purification tank 1 and a multistage filtering mechanism 2 installed on the upper end of the water purification tank 1.

[0022] The multistage filtering mechanism 2 comprises two arc-shaped through grooves 201 opened on the top of the water purification tank 1, the inner walls of the two arc-shaped through grooves 201 are both connected with mounting snap rings 202, the bottom of the outer wall of the two mounting snap rings 202 is designed into a concave shape, the edge of one side of the inner wall of the two mounting snap rings 202 is both fixedly provided with first filter screens 203, the filter holes on the upper end of the two first filter screens 203 become smaller from front to back, a supporting frame 204 is installed at the middle position of the top of the water purification tank 1, the inner walls of the two ends of the supporting frame 204 are both installed with electric push rods 205, the output ends of the two electric push rods 205 are both fixedly provided with connecting frames 206, the bottom of the two connecting frames 206 is rotatably connected with rollers 207, the outer walls of the two rollers 207 are respectively in contact with the outer wall of the water purification tank 1 and the outer wall of the two mounting snap rings 202, a plurality of arc-shaped connecting strips 208 are fixedly provided at the water purification tank 1 on one side at equal intervals, one end of each arc-shaped connecting strip 208 is fixedly provided with a water purification tank 209, the inner wall of the water purification tank 209 is connected with a fixed frame 210, the edge of the bottom of the inner wall of the fixed frame 210 is fixedly provided with a second filter screen 211.

[0023] In use, the monitored water flow is introduced into the water purification tank 1 for flowing, and the flowing water is preliminarily filtered through the first filter screen 203 on the upper end of the two mounting clamps 202 installed in the water purification tank 1, and the holes of the two first filter screens 203 gradually decrease, so that the water flow is doubly filtered in the water purification tank 1, and then the filtered water flow flows into the lower water purification tank 209 through the connecting pipe 212, and since the fixing frame 210 is clamped in the water purification tank 209, and the upper and lower sides of the fixing frame 210 are in close contact with the inner wall of the water purification tank 209, the water flow is filtered again by the more precise second filter screen 211 in the fixing frame 210, and finally the collected water is discharged through the drain pipe 7 at the bottom of the water purification tank 209. In the filtering process, the intercepted impurities in the water fall into the inside of the two mounting clamps 202 and the inside of the fixing frame 210, respectively. When the filter screen needs to be replaced or cleaned later, the electric push rod 205 on the support frame 204 is started to drive the connecting frame 206 to move, so that the connecting frame 206 rolls with the rollers 207 on the water purification tank 1 to make the two mounting clamps 202 sequentially disengage from the arc-shaped through slot 201, and then the mounting clamps 202 can be pulled out for replacement or cleaning. In the process of pulling out the mounting clamps 202, since the water flow direction brings the impurities into the inside of the mounting clamps 202, the impurities will not scratch the inner wall of the water purification tank 1 when disengaging from the arc-shaped through slot 201, thereby avoiding the phenomenon that the impurities are brought into the water purification tank 1 to cause secondary water pollution. After cleaning, the mounting clamps 202 are clamped into the original position, the electric push rod 205 is started to drive the rollers 207 to move to the upper side of the mounting clamps 202 to press them, so as to complete the installation and reset of the filtering structure. The second filter screen 211 in the water purification tank 209 can be opened by the protective cover 3, and the fixing frame 210 can be pulled out, and in the process of pulling out the fixing frame 210, the impurities are also collected in the inside of the fixing frame 210, and the impurities are not easily scraped into the water purification tank 209 due to scratching, thereby solving the problems of inconvenience in replacing the filtering element of the ordinary filtering device and the impurities being scraped into the equipment to cause secondary pollution of the water sample during replacement in actual use.

[0024] Further, the top of the water purification tank 209 is connected with the connecting pipe 212, one end of the connecting pipe 212 is connected with one side of the water purification tank 1, both ends of the fixing frame 210 are connected with the connecting buckles 213, the outer wall of one end of the two connecting buckles 213 is sleeved with the spring 214, and both ends of the two springs 214 are fixedly connected with one side of the fixing frame 210 and one side of the two connecting buckles 213, respectively. Figure 4As shown, the inner wall of the water purification tank 209 can be in close contact with the upper and lower sides of the fixed frame 210. After being clamped into the fixed frame 210, the protective cover 3 is closed to extrude the connecting buckle 213 and compress the spring 214, so that the fixed frame 210 is also forced to be fully clamped into the water purification tank 209 and in close contact with it, preventing water seepage;

[0025] Further, the water purification tank 209 is hingedly connected with a protective cover 3 on one side. The two ends of the water purification tank 209 and the two ends of the protective cover 3 are fixedly provided with limiting rings 4. The inner walls of the four limiting rings 4 are inserted and connected with a double-headed bolt 5. After the protective cover 3 extrudes the connecting buckle 213 to tightly clamp the fixed frame 210, the double-headed bolt 5 is inserted into the interfaces of the limiting rings 4 on both sides of the protective cover 3 and the water purification tank 209 to fix them, preventing them from falling off.

[0026] Further, one end of the water purification tank 1 is inserted and connected with a water inlet pipe 6, and the bottom of the water purification tank 209 is inserted and connected with a drain pipe 7. The inner wall of the drain pipe 7 communicates with the inner wall of the water purification tank 209, the inner wall of the connecting pipe 212, and the inner wall of the water purification tank 1. The top of the water inlet pipe 6 and the top of the drain pipe 7 are both installed with a sealing valve 8. When replacing the first filter screen 203 and the second filter screen 211, the sealing valve 8 on the water inlet pipe 6 can be closed to interrupt the water flow, facilitating replacement. After water purification, the sealing valve 8 on the drain pipe 7 can be opened for water drainage.

[0027] Further, the bottom of the water purification tank 1 is installed with a supporting base 9. The lower edges of the inner walls of the water purification tank 1 are both provided with arc-shaped grooves 10, and the two arc-shaped grooves 10 are respectively located directly below the two arc-shaped through grooves 201. The outer walls of the two ends of the two mounting clamping rings 202 are respectively inserted and connected with the inner walls of the two arc-shaped through grooves 201 and the inner walls of the two arc-shaped grooves 10. The outer walls of the two mounting clamping rings 202 and the upper and lower sides of the fixed frame 210 are both fixedly provided with water blocking strips 11. The water blocking strips 11 on both sides of the two mounting clamping rings 202 and the fixed frame 210 are in full contact with the inner walls of the water purification tank 1 and the water purification tank 209, achieving sealing and preventing water seepage. Moreover, the lower ends of the inner walls of the water purification tank 1 are provided with arc-shaped grooves 10, and the bottoms of the two mounting clamping rings 202 are designed in a concave shape. When the mounting clamping rings 202 are clamped into the water purification tank 1 through the arc-shaped through grooves 201, the bottoms are inserted into the arc-shaped grooves 10, so that the inner walls of the bottoms of the mounting clamping rings 202 are flush with the bottom of the inner wall of the water purification tank 1, facilitating the entry and interception of impurities.
