Problems solved by technology

[0006] Although it can be used for soil sampling under normal conditions, when the underwater sediment situation is complicated, especially when the closed shovel is caught by stones, the closed shovel cannot be closed at this time, but the operator cannot know the actual closure of the closed shovel, and Unable to control the state of the closed shovel, the sediment in the sampling cylinder has already leaked out after the sampling cylinder is pulled out of the water surface, resulting in the need for frequent multiple sampling at a single point, which is time-consuming and labor-intensive, seriously affecting the efficient, convenient and comfortable sediment collection sampling use, for this purpose, we propose a sediment sampling device

Embodiment 1

[0037] see Figure 1-7 , the present invention provides a technical solution: a sediment sampling device, including a box body 1, installation shafts 11 are arranged on both sides of the box body 1, and two installation shafts 11 are provided at the opening position of the bottom of the box body 1. A closing shovel 12, the casing 1, the mounting shaft 11 and the closing shovel 12 are all conventional structures of the prior art, and will not be repeated here;

[0038] An extension rod 13 is arranged on each closing shovel 12, and a hollow hose 14 is arranged on the box body 1. During actual use, the hollow hose 14 is used instead of the pull rope for traction.

[0039] A hard straight pipe 16 is arranged at the top handle of the box body 1, the bottom of the hard straight pipe 16 is sealed, and the hollow hose 14 is connected and fixed on the top of the hard straight pipe 16, and connecting pipes 17 are connected and fixed on both sides of the hard straight pipe 16;

Abstract

The invention discloses sediment sampling equipment which comprises a box body, mounting shafts are arranged on the two sides of the box body, two closed shovels are arranged at the opening position of the bottom of the box body through the two mounting shafts, and an elastic piece is arranged between the two closed shovels so that the two closed shovels can be kept in an open state. Different from the prior art, in the real-time sediment sampling process, the hollow hose is used for replacing a traction rope, the hollow hose can be wound for portability, air can be injected through the hollow hose, and then the injected air is used for driving the piston type shifting piece to move to close the closing shovel; and the controllability of the closing shovel in the closing process is ensured.

Description

technical field [0001] The invention relates to the technical field of sediment samplers, in particular to a sediment sampling device. Background technique [0002] The sediment sampler is an instrument for taking suspended sediment water samples, transported sediment and bed sand samples in rivers in order to determine the sediment content, sediment transport rate and sediment particle matching. [0003] Among them, there are two types of suspended mass samplers: instantaneous type and time-integrated type; the commonly used forms of moving mass samplers are basket type and differential pressure type; and there are many types of bed sand samplers, which are useful for pebble river beds. There are clam-type samplers that use impact force to dig surface samples, semi-column-shaped bucket samplers that are used in sediment river beds and installed at the bottom of lead fish, and drag-bucket samplers that are dragged along the river bed for sampling device, and the vertical sa...
