[0002] Water quality sampling in water conservancy projects involves collecting water samples from polluted water bodies and analyzing them to obtain basic data on water pollution. The water samples used for analysis should be representative and reflect the chemical composition and characteristics of the water body. Therefore, the demand for water quality sampling devices for water conservancy projects is increasing.

[0003] A search revealed a water quality sampling device disclosed in Chinese patent application number 202120442338.8. This patent relates to the field of water quality sampling technology, and more particularly to a water quality sampling device comprising a platform and a turntable. A rotating rod is vertically mounted on the platform, and the turntable passes through the rotating rod. A winch is mounted on the turntable, and a rotating shaft is mounted on the winch. A connecting rope is wound around the rotating shaft, and a sampling bucket is attached to the end of the connecting rope furthest from the winch. This patent has the advantage of facilitating sampling from different positions on the water surface.

[0004] While this patent facilitates sampling from different locations on the water surface, in practical use, it lacks a sample retention mechanism after sampling at different locations, making it difficult to retain and store water samples from different locations for subsequent testing and storage.

[0005] Therefore, a water quality sampling device for water conservancy projects is needed to solve the above-mentioned problems. Utility Model Content

A storage box is fixedly connected to the top of the base 1 and is correspondingly set with the sampling bucket 17. A control panel 18 is fixedly connected to the top of the storage box 2 and is electrically connected to the rotary motor 9, the electric push rod 10, the deflection motor, the electric telescopic rod 13, and the winding motor.

[0019] refer to Figure 5A fastening gear 19 is fixedly connected to the surface of the rotating column 8. A fixing block 20 is fixedly connected to the top of the base 1. A cavity 21 is opened inside the fixing block 20. A fastening tooth block 22 is slidably connected to the inner wall of the cavity 21. The fastening tooth block 22 is correspondingly arranged with the fastening gear 19. A connecting block 23 is fixedly connected to the inner wall of the cavity 21. A rotating rod 24 is fixedly connected to the other end of the fastening tooth block 22. The rotating rod 24 passes through the connecting block 23 and is rotatably connected to it.

[0020] This embodiment, through the arrangement of fastening gear 19, fixing block 20, cavity 21, fastening tooth block 22, connecting block 23, rotating rod 24 and spring 25, can position the rotation of rotating column 8 and avoid it from rotating during the sampling process of sampling bucket 17.

[0021] refer to Figure 6 The surface of the fixed block 20 is provided with a toggle groove 26, and the toggle groove 26 is slidably connected to the rotating rod 24. The surface of the toggle groove 26 is symmetrically provided with a limiting groove 27, and the limiting groove 27 is correspondingly provided to the rotating rod 24.

[0022] In this embodiment, the position of the fastening tooth block 22 can be positioned by setting the actuating groove 26 and the limiting groove 27, which facilitates the rotation and braking of the rotating column 8 and makes it easier for the operator to operate the fastening tooth block 22.

[0023] refer to Figure 3 The inner wall of the groove 4 is symmetrically provided with limiting grooves 28, and the surface of the bearing plate 5 is symmetrically provided with limiting blocks 29, and the limiting blocks 29 are slidably connected to the limiting grooves 28.

[0024] In this embodiment, the movement trajectory of the bearing plate 5 can be restricted by the setting of the limiting groove 28 and the limiting block 29, so as to prevent the bearing plate 5 from sliding out of the groove 4.

[0025] refer to Figure 3 and Figure 4 Several marking blocks 30 are fixedly connected to the surface of the bearing plate 5, and the marking blocks 30 correspond one-to-one with several insertion ports 6. The insertion ports 6 and the inner walls of the support frame 7 are both fixedly connected with shock-absorbing pads.

[0026] In this embodiment, the marking block 30 makes it easy for staff to mark the storage time and location of the sample bottle in the insertion port 6, which is convenient for subsequent use or observation. The shock-absorbing pad can protect the surface of the sample bottle and prevent it from colliding with the insertion port 6 and the support frame 7.

[0027] refer to Figure 1 The sampling barrel 17 has a sampling groove on its surface, and a number of sampling holes 31 are provided on the surface of the sampling groove. The number of sampling holes 31 are arranged in a ring and are uniformly arranged. A counterweight 32 is fixedly connected to the bottom of the sampling barrel 17.

[0028] In this embodiment, the sampling groove and sampling hole 31 facilitate the sampling bucket 17 to draw in water samples. The counterweight 32 increases the weight of the sampling bucket 17 and improves the sampling rate of the sampling bucket 17.

[0029] refer to Figure 1 The base 1 has protective grooves at all four corners, and protective wheels 33 are rotatably connected to the inner wall of the protective grooves.

[0030] In this embodiment, the four corners of the base 1 can be protected by the protective groove and the protective wheel 33, and the rotating protective wheel 33 can guide and deflect the impact of foreign objects.

[0031] refer to Figure 1 and Figure 2 The top of the sample storage box 2 is symmetrically fixedly connected with a snap-fit ​​block 34. The top of the snap-fit ​​block 34 is provided with an arc-shaped groove 35, and the arc-shaped groove 35 is correspondingly set with the electric telescopic rod 13. The inner wall of the arc-shaped groove 35 is fixedly connected with an anti-slip pad.

[0032] In this embodiment, the electric telescopic rod 13 can be stored by setting the snap-fit ​​block 34 and the arc groove 35, so as to avoid the electric telescopic rod 13 and related components from shaking and colliding and being damaged when the water quality sampling device is moved.

[0033] This invention uses a pusher to move the sample storage box 2 to a designated position via brakeable casters on the base 1, then brakes it. The rotating rod 24 then slides from the inner limiting groove 27 along the actuating groove 26 to the outer rotating rod 24, causing the fastening tooth block 22 to disengage from the fastening gear 19 and compress the spring 25. Next, the deflection motor can be activated via the control panel 18 to drive the hinge block 12 within the hinge member 11 to deflect. The storage box is then opened, and the sampling bucket 17 is removed, its threads rotating into the threaded block at the other end of the connecting rope 16. At this point, the rotating motor 9 can be activated to rotate the rotating column 8, thereby adjusting the horizontal rotation position of the sampling bucket 17. When the horizontal position of the sampling bucket 17 is adjusted... After completion, the rotating rod 24 can be returned to its original position. At this time, the reaction force of the spring 25 pushes the meshing fastening block 22 to mesh with the fastening gear 19, which can position the rotating column 8. Then, the electric push rod 10 can be activated to adjust the height of the hinge block 12, and the extension length of the sampling bucket 17 can be adjusted by the electric telescopic rod 13. The connecting rope 16 of the winch 15 can be adjusted by the winding motor, thereby controlling the sampling bucket 17 to sample the water. After the sampling bucket 17 finishes sampling, the double door can be opened, and the bearing plate 5 can be slid outward by the handle. Then, the sample bottle can be taken out to retain the water sample in the sampling bucket 17. The retained water sample can be marked by the marking block 30 for subsequent testing.
