[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] like Figure 1-7 As shown, the water quality monitoring sampling device includes an installation pipe 1, an internal telescopic component connected to the installation pipe 1, an installation plate 5 fixedly installed on one side of the installation pipe 1, and a fixed-depth sampling component connected to the middle of the plate 5.
[0028] The telescopic assembly includes a motor 2, the output shaft of which is fixedly connected to a lead screw 13. A nut seat 14 is threadedly connected to the outside of the lead screw 13. A telescopic tube 12 is fixedly connected to the outside of the nut seat 14. A connecting block 11 is fixedly installed on one side of the telescopic tube 12. A U-shaped plate 6 is fixedly connected to the other side of the connecting block 11 by welding. A slot is opened on one side of the mounting tube 1 for the connecting block 11 to move, so that the connecting block 11 can move freely with the telescopic tube 12.
[0029] The fixed-depth sampling assembly includes a fixed rod 3, a limiting plate 20, and a control tube 19. The fixed rod 3 is slidably connected inside the control tube 19. An operating handle 4 is fixedly connected to the top of the fixed rod 3, and a limiting block 22 is fixedly installed at the bottom of the fixed rod 3. A limiting plate 23 adapted to the limiting block 22 is fixedly installed inside the control tube 19, so that when the operating handle 4 is rotated, the fixed rod 3 and the control tube 19 can rotate synchronously. A limiting pin 21 is fixedly installed at the bottom of the control tube 19. The limiting pin 21 is located inside the limiting plate 20. The limiting plate 20 is hollow inside, and its surface has a moving groove for the limiting pin 21 to be pulled out. When the limiting pin 21 is rotated to the moving groove, it can be lifted. When the limiting pin 21 is inside the limiting plate 20, it can drive the fixed-depth sampling assembly to move with the U-shaped plate 6 under the action of the limiting plate 20. Therefore, the inlet pipe assembly will not be opened when the U-shaped plate 6 descends. One end of the limiting plate 20 is fixedly installed... Sampling boxes 7 are fixedly installed at equal intervals on the inner wall of the U-shaped plate 6 at the bottom inside the plate 6. A water outlet pipe 8 is connected to one side of the sampling box 7, and the water outlet pipe 8 is equipped with a valve. A water inlet pipe assembly is connected to the top of the sampling box 7. The water inlet pipe assembly is connected to the control pipe 19 through a pull rope 9. When the operating handle 4 is lifted, the water inlet pipe assembly can be opened by controlling the pull rope 9 through the control pipe 19. The bottom of the pull rope 9 abuts against a guide rope groove 10. One end of the guide rope groove 10 is fixedly installed on the inner wall surface of the U-shaped plate 6. A pulley shaft is rotatably connected to one side of the guide rope groove 10. The pulley shaft abuts against the pull rope 9. The pulley can greatly reduce the wear rate of the pull rope 9 and increase its service life. One end of the pull rope 9 is provided with a connection hole for the control pipe 19 to pass through. The surface of the control pipe 19 is provided with concave rings 15 at equal intervals. The pull rope 9 is sleeved on the inner side of the concave rings 15. Thus, the pull rope 9 only moves up and down with the control pipe 19 and will not rotate with the control pipe 19 and become entangled on the surface of the control pipe 19.
[0030] The water inlet pipe assembly consists of a pipe body 16, a spring 17, and a stopper 18. The spring 17 is fixedly installed on the top of the inner wall of the pipe body 16, and the stopper 18 is fixedly installed at the bottom of the spring 17. The stopper 18 is a flat-topped cone and abuts against the bottom of the inside of the pipe body 16. The top of the stopper 18 is fixedly connected to the pull rope 9. Under the action of the spring 17, the stopper 18 can be tightly blocked inside the pipe body 16. The stopper 18 can only be opened by pulling the pull rope 9 to achieve the purpose of controlling the water inlet.
[0031] In practical applications, the operator places the device described in this utility model in a designated water area, turns on the motor 2, lowers the sump plate 6 through the telescopic component, turns off the motor 2 when it reaches the designated depth, rotates the operating handle 4, and lifts the operating handle 4 when the limiting pin 21 is rotated to the moving groove of the limiting plate 20. Lifting the operating handle 4 drives the pull rope 9 connected to the control pipe 19 to open all the water inlet pipe assemblies at different water levels. The device begins to sample different water levels simultaneously. After sampling is completed, the operating handle 4 is pressed down to close all the water inlet pipe assemblies. At this time, the limiting pin 21 is inserted into the limiting plate 20. Rotating the operating handle 4 will re-lock the limiting pin 21 in the limiting plate 20. Then, the device is reversed and the motor 2 is turned on to lift the sump plate 6. The water outlet pipe 8 is then opened to put the sampled tube into the sampling bottle.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
