[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0022] To address the problems existing in the background technology, this application proposes the following technical solution: a novel flowing water sampling device.

[0023] The specific technical solution includes a base plate 1; a turntable 2 is rotatably connected to the upper surface of the base plate 1, a connecting block 3 is fixedly installed on the upper surface of the turntable 2, a rope 4 is provided on one side of the connecting block 3, a circular collection box 5 is fixedly installed at one end of the rope 4, a protective component 6 is provided on the outside of the circular collection box 5, the protective component 6 includes a support block 61, a return spring 62, a damper 63, a sliding block 64, a connecting rod 65, a shaped block 66, and a cylindrical protective plate 67, the support block 61 is fixedly installed on the outside of the circular collection box 5, and a groove is opened on one side of the support block 61.

[0024] One end of the return spring 62 and the damper 63 are both fixedly installed on the damper 63, and the return spring 62 is sleeved on the damper 63. The sliding block 64 is slidably connected in the groove, and the other end of the return spring 62 and the damper 63 are both fixedly installed on the sliding block 64. The two ends of the connecting rod 65 are respectively hinged to the sliding block 64 and the irregular block 66. The outer side of the irregular block 66 is fixedly installed on the inner side of the cylindrical protective plate 67. The outer side of the cylindrical protective plate 67 is provided with filter holes. Through the filter holes, stones or granular objects in the flow can be filtered to avoid impurities from being mixed into the flowing water during sampling, which would affect the accuracy of the sampling.

[0025] The circular collection box 5 has an installation cavity, and a rotating rod 7 is rotatably connected inside the installation cavity. A sealing plate 8 is fixedly installed on the outside of the rotating rod 7, and one end of the sealing plate 8 is slidably connected to the inner wall of the installation cavity. A servo motor 9 is fixedly installed on one side of the circular collection box 5, and the output end of the servo motor 9 passes through the installation cavity and is fixedly installed on the rotating rod 7. A water inlet 10 is provided on the outside of the circular collection box 5, and flowing water can be collected into the circular collection box 5 through the water inlet 10.

[0026] A stranding roller 11 is fixedly installed on one side of the connecting block 3, and one end of the rope 4 is fixedly installed on the stranding roller 11. A stepper motor 12 is fixedly installed on one side of the connecting block 3, and the output end of the stepper motor 12 passes through the connecting block 3 and is fixedly installed on the stranding roller 11. A traction block 13 is fixedly installed on one side of the connecting block 3. The stranding roller 11 can drive the circular collection box 5 at one end of the rope 4 to sink into the water for sampling.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, the stepper motor 12 is started, driving the strand roller 11 to rotate. Then, the turntable 2 rotates, causing the circular collection box 5 at one end of the rope 4 to move into the water, allowing it to sink into the flowing water. As the water flows, stones, branches, and other debris are carried by the current and impact the circular collection box 5. At this time, the cylindrical protective plate 67 can be used to block the debris, ensuring that the stones, branches, and other debris only impact the cylindrical protective plate 67. The resulting impact force is transmitted to the sliding block 64 at one end of the connecting rod 65. The elasticity of the return spring 62 at one end of the sliding block 64 and the damping effect of the damper 63 can control the sliding motion. Block 64 provides buffering and shock absorption, thereby buffering and absorbing the impact on the cylindrical protective plate 67. Then, the servo motor 9 can be started, which drives the rotating rod 7 to rotate, allowing some water to enter the circular collection box 5 through the inlet 10. When one compartment of the circular collection box 5 is full of water, the sealing plate 8 can be rotated to expose the other compartment of the circular collection box 5, which facilitates multiple sampling of the flowing water and enhances its practicality. During the sampling of the flowing water, the flowing water can be simply filtered through the filter holes in the cylindrical protective plate 67 to prevent particulate matter from entering the circular collection box 5, thereby increasing the accuracy of the flowing water sampling.

[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
