Accordingly, under certain water conditions, such as a large amount of wood or the like, coastal aquaculture areas and the like, the cutter teeth of the reamer are easy to insert into the wood or roll up strips of fishing nets, kelp and the like during the dredging construction process, and finally, the gap between adjacent cutter arms of the reamer is blocked, so that the reamer is failed and the continuous excavation cannot be carried out. Therefore, the cleaning work of the above-mentioned obstacles (impurities) is very important for the dredging construction work, and directly determines the progress of the construction and the cost of the construction.
The existing obstacle cleaner generally comprises a cross beam with a plurality of hooks, when the obstacle cleaner is used, a tugboat and a rope are adopted to pull the cross beam to move under the water, the hooks hook sundries and obstacles such as fishing nets, kelp, strip-shaped sapwood and the like, the cleaner is lifted by a lifting machine after being pulled for a certain time, and the cleaner is moved to the tugboat or cleaned on the land and then put into use again.
The cleaner with the structure has insufficient stability when moving underwater, and is easy to roll when encountering large obstacles, thereby causing cleaning failure. The actual conditions of the construction project are as follows: the distribution of underwater sundries and obstacles is quite complex and changeable, the hooks of the cleaner with the structure are usually positioned at the bottom of the cross beam, so that only net-shaped sundries settled at the bottom or semi-buried at the bottom can be hooked and cleaned, and obstacles such as net-shaped sundries suspended at the bottom, blocky rotten wood and the like do not have cleaning capacity, so that the water area for dredging construction cannot be thoroughly cleaned in the engineering, and the dredging construction is seriously influenced. Therefore, there is a need for a structurally optimized design of the obstacle clearing device.
