[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0028] See also Figures 1 to 9 A water intake device for water quality monitoring includes a cylinder 1 and a cover 2. A slide rail 3 is provided on the inner wall of the cylinder 1. A slider 5 is provided to slide with the slide rail 3. An isolation plate 4 is provided in the cylinder 1. A first sealing ring 101 is fixed to the outer side of the isolation plate 4. The first sealing ring 101 is fixed to the slider 5. A water inlet pipe 13 is provided on the wall of the cylinder 1. Before water is introduced into the cylinder 1, the isolation plate 4 is located below the water inlet pipe 13.

[0029] Furthermore, a through hole 6 is opened on the cover body 2, and a second sealing ring 102 is fixed on the through hole 6. A movable pull rope 7 is arranged on the second sealing ring 102, and one end of the pull rope 7 is fixed to the bottom of the cylinder body 1. A scale rope 21 capable of measuring the length is fixed above the cover body 2. When water of a water level is taken out, the pull rope 7 is pulled upward to drive the isolation plate 4 to slide up on the slide rail 3, so as to provide the first water sample to be isolated in the upper part of the cylinder body 1 through the isolation plate 4. Through the arrangement of the first sealing ring 101 and the second sealing ring 102, the first water sample is prevented from being mixed and the first water sample is prevented from dripping into the water of the second water sample, thereby affecting the detection data of the second water sample.

[0030] In this embodiment, in order to provide a pull rope 7 to pull the isolation plate 4 up to the middle position inside the cylinder 1 to prevent the isolation plate 4 from sliding down, as shown in the figure, a sleeve 8 is provided on the wall of the cylinder 1, a spring 9 is fixed to the bottom of the sleeve 8, a first inclined block 201 is fixed to the upper end of the spring 9, the first inclined block 201 is located at the upper end of the slide rail 3, a rope body 10 is fixed to the bottom of the first inclined block 201, one end of the rope body 10 passes through the bottom of the sleeve 8, to prevent the rope body 10 from being unable to be taken out in the sleeve 8, a pull block 11 is fixed to the end of the rope body 10 located outside the sleeve 8.

[0031] Furthermore, a support plate 12 is fixed on the slider 5, and a second inclined block 202 is fixed on the support plate 12. When the pull rope 7 is pulled upward, the inclined wall of the first inclined block 201 is located within the travel range of the second inclined block 202, and the spring 9 contracts. When the second inclined block 202 is located above the first inclined block 201, the spring 9 is reset to provide a limit for the isolation plate 4 to prevent the isolation plate 4 from slipping. When a water sample test is completed, when a second water sample is to be collected, the isolation plate 4 is limited and cannot slide down. It is only necessary to pull the pull blocks 11 on both sides outside the cylinder 1. At this time, the spring 9 contracts, the second inclined block 202 loses its limit, and the isolation plate 4 can slide down to the bottom of the cylinder 1 to collect water again.

[0032] A motor 15 is provided on one side of the water inlet pipe 13. Preferably, the motor 15 is a waterproof motor to prevent the motor 15 from being damaged by water. The motor 15 is fixed on the outer wall of the cylinder 1. The output shaft of the motor 15 is rotatably connected with a screw rod 16. A nut 17 is provided on the screw rod 16. A first connecting rod 301 is provided on the nut 17. One end of the first connecting rod 301 is fixed to one side of the sealing cover 14. A vertical rod 18 is provided on the other side of the water inlet pipe 13. A slide groove 19 is provided on the vertical rod 18. A sliding member 20 is provided on the slide groove 19. The first connecting rod 301 is fixed on the nut 17. The first connecting rod 301 is fixed to one side of the sealing cover 14. The sliding member 20 is provided with a second connecting rod 301. Rod 302, the second connecting rod 302 is fixed on the other side of the sealing cover 14, the second connecting rod 302 is used to limit the sealing cover 14, a controller 22 is arranged outside the cylinder 1, and a switch 23 for the motor 15 to rotate upward or downward is arranged on the controller 22. When the cylinder 1 reaches the water level to be detected, the switch 23 for the motor 15 to rotate upward is pressed, and the sealing cover 14 drives the sliding member 20 to slide upward through the upward rotation of the nut 17, so that the sealing cover 14 is separated from the water inlet pipe 13 for water to enter. After the water is filled, the switch 23 for the motor 15 to work downward is pressed in time, so that the sealing cover 14 can block the water inlet pipe 13 in time to prevent the water sample from mixing.

[0033] When the water in the cylinder 1 needs to be collected into a detection container, the water in the upper half of the cylinder 1 can be collected by opening the cover 2 , and the water in the lower half of the cylinder 1 can be collected by opening the water outlet pipe 13 .

[0034] Working principle: by measuring the length of the graduated rope 21, the cylinder 1 is placed into the water level to be detected. After reaching the water level, the switch 23 for the motor 15 to work upward is turned on, and the sealing cover 14 is separated from the water inlet pipe 13, so that water is allowed to enter. After water collection at one water level is completed, the switch 23 for the motor 15 to work downward is turned on, and the sealing cover 14 blocks the water inlet pipe 13 to prevent the water sample from mixing. Then, the isolation plate 4 is slid upward by the pull rope 7, and the inclined wall of the second inclined block 202 is pulled upward along the inclined wall of the first inclined block 201. At this time, the spring 9 contracts. When the second inclined block 202 is located above the first inclined block 201, the spring 9 is stretched and reset to limit the isolation plate 4 to prevent it from slipping, and then the graduated rope 21 is pulled down to sample and collect water at the next water level.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
