River sludge extraction device

Abstract

The invention discloses a river sludge extraction device which comprises a spliced sphere. A spherical cavity is arranged in the middle of the sphere; a convex ring is arranged on the upper end surface, close to the circle part, of the sphere; a limiting cavity communicated with the spherical cavity is arranged in the convex ring; four air bag balls are embedded in the front and back surfaces andthe left and right surfaces in the limiting cavity separately; one end of each air bag ball is provided with a convex air outlet; and the air outlet penetrates through the sphere and extends to the outside. According to the sludge extraction device, sludge in different positions can be automatically extracted in a free dragging process; area can be divided and extracted without electronic components; only one small sphere structure is needed; and the operation is simple, and detection values of extracts are more accurate.

Description

Technical field [0001] The invention relates to the field of environmental protection, in particular to a river sludge extraction device. Background technique [0002] River silt extraction and testing is a necessary step to detect the ecological environment of the river. Environmental protection personnel need to regularly extract the silt in the river and bring it back for testing. However, the detection result of only extracting silt from one location does not represent the detection structure of the entire river. Therefore, workers often need to carry multiple extractors, and then extract and detect multiple points in different areas. This method uses a larger number of extractors. The operation is inconvenient, the whole process is often interrupted, and it takes a long time to extract multiple points from one extraction device. Some people in the current technology have designed some extraction devices that can collect multiple points, but this kind of extraction device ha...

Problems solved by technology

However, the result of only extracting the silt from one location for detection cannot represent the detection structure of the entire river channel. Therefore, the staff often need to carry multiple extractors, and then extract and detect at multiple points in different regions. The number of extractors used in this way is relatively small. Many, inconvenient to operate, the whole process is often interrupted, it takes a long time, and it is impossible to realize multi-point extraction of an extraction device

Some people in the prior art have designed some extraction devices that can collect multiple points, but the structure of this extraction device is complex, and electronic devices are needed to complete the extraction of different points, which is very inconvenient
