[0032] As Figures 1-4 shown, the present utility model provides an environmental water quality sampling device having a top plate 1. Among them, a driving disk 21 and a driven disk 31 are rotatably connected to the top plate 1. The middle part of the driven disk 31 is fixedly installed with a mounting disk 33 located below the driven disk 31 through a connecting rod 32.

[0033] A plurality of mounting grooves 40 are equidistantly arranged along the circumference of the mounting disk 33. A plurality of strip-shaped grooves 34 corresponding to the mounting grooves 40 are formed on the driven disk 31. A driving column 22 is fixedly installed on the driving disk 21, and the driving column 22 is slidably connected to the strip-shaped grooves 34.

[0034] Samplers 41 are installed on the mounting grooves 40. A water intake chamber is formed in the sampler 41. The upper end of the outer wall of the sampler 41 is fixedly installed with a water inlet pipe 44, and the lower end of the outer wall of the sampler 41 is fixedly installed with a water outlet pipe 45. Both the water inlet pipe 44 and the water outlet pipe 45 are communicated with the water intake chamber.

[0035] Optionally, in the above technical solution, a first sliding groove 51 is formed on the arc-shaped inner side wall of the mounting groove 40, and a second sliding groove 52 is formed inside the mounting groove 40. The first sliding groove 51 and the second sliding groove 52 are communicated with each other.

[0036] Optionally, in the above technical solution, a first sliding rod 61 slidably connected to the first sliding groove 51 is fixedly installed on the outer side wall of the sampler 41, and a second sliding rod 62 slidably connected to the second sliding groove 52 is fixedly installed on the first sliding rod 61.

[0037] Optionally, in the above technical solution, a support frame 10 is provided above the top plate 1. The movable end of a telescopic cylinder 11 is fixedly installed on the top of the top plate 1, and the fixed end of the telescopic cylinder 11 is fixedly installed on the top wall of the support frame 10.

[0038] Optionally, in the above technical solution, two guide rods 12 are symmetrically and fixedly installed on the top of the top plate 1 with respect to the telescopic cylinder 11. The guide rods 12 extend upward through the top wall of the support frame 10 and are slidably connected thereto.

[0039] Optionally, in the above technical solution, a first driving motor 13 is fixedly installed on the top of the top plate 1. The output shaft of the first driving motor 13 penetrates through the top plate 1 and is fixedly connected to the middle of a driving disk 21.

[0040] Among them, the first driving motor 13 is a reduction motor.

[0041] Among them, a one-way water inlet valve is installed in the water inlet pipe 44, and a one-way water outlet valve is installed in the water outlet pipe 45.

[0042] Working principle:

[0043] During use, the sampler 41 is snap-fitted onto the installation groove 40 through the first slide bar 61 and the second slide bar 62. The support frame 10 is placed on the ground at the sampling location. The telescopic cylinder 11 is started to drive the top plate 1 to move downward until the sampler 41 moves to the required depth. The one-way water inlet valve in the water inlet pipe 44 is opened to allow water to flow into the sampler 41 for water quality sampling.

[0044] When sampling is required at the same location, after the previous sampler 41 has completed sampling, the first driving motor 13 is started to drive the driving disk 21 to rotate. The driving column 22 on the driving disk 21 drives the driven disk 31 to rotate through the strip-shaped groove 34. The driving column 22 slides into one strip-shaped groove 34. When it slides out of this strip-shaped groove 34, the sampler 41 corresponding to this strip-shaped groove 34 moves to the position of the previously completed sampling sampler 41, that is, the adjacent sampler 41 moves to the position of the completed sampling sampler 41 for repeated sampling. When it is necessary to adjust the depth of the sampler 41, the telescopic cylinder 11 is started to drive the top plate 1 to move up and down.

[0045] After sampling is completed, the sampler 41 is removed from the installation groove 40 through the first slide bar 61 and the second slide bar 62, and the water quality can be taken out by opening the valve in the water outlet pipe 45.

[0046] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
