Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a drainage device used in water conservancy projects. Background Art

[0002] Farmland irrigation has always been a water conservancy project that the country attaches great importance to. In the past, farmland irrigation was done by building a pond between many farmlands. The water from a large freshwater river was regularly fed into the pond through a sluice gate to allow farmers to irrigate the farmland. With the development of the country, many farmlands are now irrigated with irrigation canals to avoid the trouble of carrying water back and forth for irrigation. In addition, in the existing canals, since most of the canals are built in the ridges of the fields, the weeds on both sides of the ridges are easy to fall into the canals, which often cause a lot of debris inside the canals.

[0003] However, the existing water conservancy projects lack drainage equipment, and it is impossible to clean and salvage blockages and sediments, which easily causes blockage at the water inlet or outlet of the water channel, resulting in the water channel being unable to be used normally;

[0004] Most of the existing patent solutions use a drive device that can move forward and backward along the length of the ditch, a drive mechanism that can move laterally in the width of the ditch, and a drive mechanism that is set in the height direction to screen and salvage and remove debris at the bottom of the ditch. The execution of the above-mentioned actions requires the joint cooperation of multiple drive mechanisms, which makes the entire device heavy and costly. In addition, the existing debris removal mechanism needs to cooperate with a debris filter box to store debris, and the debris filter box usually needs to be symmetrically provided with two detachable snap-in structures to realize the removal of debris from the filter box or the replacement of the filter box, and the two snap-in mechanisms generally require both hands to operate at the same time, which makes the operation inconvenient. Summary of the invention
