DETAILED DESCRIPTION

[0034] The following will be described in detail with reference to the accompanying drawings. Figures 1-7 The application is further described in detail.

[0035] The application discloses a water quality sampling device. Referring to Figure 1 and Figure 2 , the water quality sampling device comprises a base 1, the base 1 is arranged in a prismatic shape, and the bottom end of the base 1 is arranged in a pyramidal shape.

[0036] Referring to Figure 2 , the base 1 is provided with a stabilizing assembly 2, and the stabilizing assembly 2 comprises a stabilizing plate 21 and an insertion column 22. The stabilizing plate 21 is hinged to each side wall of the base 1, and the insertion column 22 is arranged on the stabilizing plate 21. One end of the insertion column 22 is fixedly connected with a conical head 221, the maximum diameter of the conical head 221 is greater than the diameter of the insertion column 22, and the other end is fixedly connected with a limiting plate 222.

[0037] When the base 1 is stabilized, the bottom end of the base 1 is inserted into the soil layer, then the stabilizing plate 21 is turned over to adhere to the surface of the soil layer, the limiting plate 222 is pressed, and the conical head 221 is inserted into the soil layer, so as to limit the degree of freedom of the base 1, thereby achieving the effect of stabilizing the base 1.

[0038] Referring to Figure 3 and Figure 4 , the top end of the base 1 is provided with a lifting rod 11 and a lifting assembly 3, the lifting rod 11 is arranged horizontally, and the lifting assembly 3 comprises an actuating ring 31, a limiting block 32 and a connecting column 33. The top end of the base 1 is provided with a lifting hole, and the limiting block 32 is fixedly connected to the inner wall of the lifting hole. The top end of the connecting column 33 is fixedly connected to the lifting rod 11, and the bottom end is inserted into the lifting hole. The surface of the connecting column 33 is provided with a limiting groove 331 along the length direction of the connecting column 33, and the limiting groove 331 is in sliding fit with the limiting block 32. The actuating ring 31 is rotationally connected to the top end of the base 1 and is in threaded fit with the connecting column 33.

[0039] When adjusting the height of the lifting rod 11, rotate the toggle ring 31 to move the lifting rod 11 from its original position, thereby achieving the effect of adjusting the height of the lifting rod 11.

[0040] Reference Figure 1 , Figure 4 and Figure 5 One end of the lifting rod 11 is fitted with an extension rod 12, which is rectangular. The other end of the lifting rod 11 is threaded with a drive screw 13, the end of which is rotatably connected to the extension rod 12. A rotating frame 14 is hinged to the end of the extension rod 12 furthest from the lifting rod 11. A rotating assembly 4 is mounted on the lifting rod 11, comprising a rotating disk 41, a connecting rod 42, a push rod 43, and a limiting frame 44. The rotating disk 41 is fixedly connected to the rotating frame 14 and coaxially arranged with it. A fixing post 411 is fixedly connected to the rotating disk 41. The limiting frame 44 is fixedly connected to the lifting rod 11. The push rod 43 is slidably fitted within the limiting frame 44. The connecting rod 42 is hinged between the connecting post 33 and the push rod 43.

[0041] When the rotating frame 14 is driven to rotate, the push rod 43 is pressed, which causes the connecting rod 42 to press against the fixed column 411, causing the rotating disk 41 to rotate, thus achieving the effect of driving the rotating frame 14 to rotate.

[0042] Reference Figure 1 , Figure 6 and Figure 7 A plurality of sampling boxes 5 are fixedly connected to the rotating frame 14. In this embodiment, four are used as an example. Each sampling box 5 is formed by two symmetrically arranged shells fixedly connected together. The sampling box 5 has a water inlet 521 and a vent 58. A partition 51 is fixedly connected inside the sampling box 5. One side of the partition 51 is a water inlet area 52, and the other side is a sliding area 53. A float 54 is slidably fitted in the water inlet area 52, and a sliding block 55 is slidably fitted in the sliding area 53. A counterweight 551 is fixedly connected to the sliding block 55. The sum of the weights of the counterweight 551 and the sliding block 55 is less than the weight of the float 54. The counterweight 551 is used to reduce the possibility of the sliding block 55 sliding and failing. A steering wheel 56 is rotatably connected inside the sampling box 5. A connecting rope 561 is fixedly connected between the float 54 and the counterweight 551. The connecting rope 561 is wound around the steering wheel 56. Both the sliding zone 53 and the water inlet zone 52 are fixedly connected with a stop 57, which is used to limit the movement of the sliding block 55 and the float 54.

[0043] Reference Figure 6 and Figure 7The sampling box 5 is equipped with a sealing component 6, which includes a magnetic block 61, a magnetic metal block 62, and a sealing plate 63. Several sliding posts are fixedly connected to the sampling box 5; in this embodiment, two posts are used as an example. The sealing plate 63 is slidably fitted onto the sliding posts. The magnetic block 61 is embedded within the sliding block 55, and the magnetic metal block 62 is embedded within the sealing plate 63 and aligned with the magnetic block 61. In this embodiment, the magnetic metal block 62 is made of an iron alloy.

[0044] When the water inlet hole 521 is blocked, the sliding block 55 moves and abuts against the inner wall of the sliding area 53. The magnetic block 61 attracts the magnetic metal block 62 to move, causing the blocking plate 63 to move and cover the water inlet hole 521, thus achieving the effect of automatically blocking the water inlet hole 521.

[0045] The implementation principle of a water sampling device according to an embodiment of this application is as follows: During sampling, the base 1 is inserted into the soil layer, the stabilizing plate 21 is flipped over, and the insertion column 22 is pressed. The conical head 221 is inserted into the soil layer to stabilize the base 1. The drive screw 13 is rotated to move the extension rod 12, which drives the rotating frame 14 to move to the designated position. Then, the push rod 43 is pressed to make the rotating disk 41 rotate, which drives the sampling box 5 to move directly below. The actuating ring 31 is rotated to make the connecting column 33 descend, and the water inlet 521 is submerged in the water. Water enters the water inlet area 52 from the water inlet 521. The float 54 rises until it touches the stop block 57. At the same time, the sliding block 55 descends and touches the bottom wall of the sliding area 53. The magnetic block 61 attracts the magnetic metal block 62. The sealing plate 63 moves and covers the water inlet 521, thus achieving the effect of sampling water.

[0046] By cooperating with the drive screw 13, lifting rod 11 and extension rod 12, the operator can adjust the length of the lifting rod 11 and extension rod according to actual needs. Compared with the prior art, the sampling range of the sampling device is increased, enabling the sampling device to adapt to the sampling needs of more locations and improving the applicability of the sampling device.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
