[0051] Example 1

[0052] This embodiment provides a dedicated wet sedimentation sampler, such as... Figures 1-4 As shown, it includes a settling cylinder 1, a cover plate 6, a water collection tank 8, a support 2, a balancing assembly, a pull rope 11, and a water collection counterweight 12; the balancing assembly includes a drive wheel 4 and a balance wheel 5 that mesh with each other;

[0053] The settling cylinder 1 is cylindrical, with a support 2 on each side. The top of the support 2 is equipped with a drive wheel 4 and a balance wheel 5. The drive wheel 4 is located on the side closer to the settling cylinder 1, and the drive wheel 4 and balance wheel 5 are meshed with each other. A frame 3 is set on the outside of the support 2, balance wheel 5 and drive wheel 4. The bottom of the settling cylinder 1 is equipped with a first fixing component - hook. The pulling rope 11 passes around the drive wheel 4, with one end fixedly connected to the hook and the other end connected to the second fixing component at the top of the water collection tank 8. The water collection tank 8 is located on the outside of the frame 3 (on the side away from the settling cylinder 1). The middle of the outside of the frame 3 is also equipped with a support plate 13 for supporting the water collection counterweight 12. The length of the support plate 13 is greater than the length of the water collection counterweight 12, and the width of the support plate 13 is greater than the width of the water collection counterweight 12.

[0054] Two identical cover plates 6 are respectively provided on the left and right sides of the top of the settling cylinder 1 along its central axis. The cover plates 6 are hinged to the top crossbeam of the frame 3. The bottom of the cover plate 6 is provided with a half gear 9 that meshes with the balance wheel 5. The top of the inner side (the side that is close to each other) of the two cover plates 6 is provided with a cover plate counterweight 7, and the outer side (the side that is far from each other) is provided with a water collection tank 8 with a top opening. The upper surface of the cover plate 6 is also provided with a rainwater guide channel 10 connected to the water collection tank 8.

[0055] Normally, the sampler is in a closed state. During heavy rain, rainwater is collected in the rainwater diversion channel 10 and gathered into the water collection tank 8. Supported by the balance wheel 5, when the torque weight of the water collection tank 8 exceeds the torque weight of the cover plate counterweight 7, according to the lever principle, the two cover plates 6 at the top of the settling cylinder 1 tilt until they are vertical, and the top of the settling cylinder 1 is fully opened, allowing rainwater to fall into the settling cylinder 1. When the rainwater is collected to the set level of the water collection counterweight, the settling cylinder 1 sinks, causing the drive wheel 4 to rotate and the water collection counterweight 12 to move upward. The rotation of the drive wheel 4 causes the balance wheel 5 to rotate, and the balance wheel 5 meshes with the half gear 9 to rotate, causing the cover plate 6 to close.

[0056] The foregoing description of the embodiments has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the application to the precise form disclosed. Modifications and variations are possible in light of the above teachings or can be acquired from practice of the application. As well, the description is presented in the context of the preferred embodiments as a number of alternatives. It is not intended to limit the application to the precise form described.
