Description

Technical Field

[0001] The utility model specifically relates to a novel sampling device for runoff sediment, belonging to the technical field of runoff sediment sampling. Background Art

[0002] Runoff refers to the water that flows along the surface or underground under the action of gravity, which is rainwater, meltwater, or watering. There are different types of runoff. According to the source of the water flow, there are rainfall runoff, meltwater runoff, and irrigation runoff; according to the flow mode, it can be divided into surface runoff and underground runoff. Surface runoff can be divided into slope flow and river channel flow. In water conservancy projects, the sediment content in the runoff needs to be sampled and tested, and when sampling, a sampling device is needed.

[0003] For example, a new type of runoff sediment sampling device disclosed in the Chinese utility model patent with publication number: CN212254765U includes a support scale, and collection tanks are uniformly and horizontally arranged on the body of the support scale. The collection tanks are connected to the support scale by screws, and the upper and lower sides of the outer wall of the support scale are sleeved, and a support rod is connected to the left side of the slide sleeve. The left ends of the two support rods are fixedly connected with a pull rod by screws. By setting collection tanks of different heights, sampling operations at different depths of water flow can be performed, which is suitable for different usage conditions; by setting the pull rod, multiple covers can be moved at the same time, so that the collection tanks can be sealed or opened at the same time, the obtained sampling samples are more accurate, and the accuracy of subsequent experiments is higher; through the cooperation of the support reset spring and the top plate, the pull rod can be quickly reset after adjustment, which is more convenient.

[0004] However, the water and sediment contained in the runoff are often poured into the interior of the container. Since the sediment is affected by gravity, when pouring into the container or when the water and sediment mixture is pumped out by a water pump, the sediment does not move with the water flow, making it impossible to accurately reflect the runoff sediment situation, resulting in inaccurate sampling and inconvenient use. In addition, when in use, the portability is low, making it inconvenient to carry sampling in multiple locations. Utility Model Content
