Abstract
The utility model relates to a desilting device, wherein, a pile is drilled into the underwater bottom mud surface with flowing current; a floating ball is connected with the tail of the pile; a desilting rope is connected with the floating ball; and a tail rudder blade is connected to the tail of the desilting rope. The desilting device is characterized in that desilting plates are hung on the desilting rope.
Description
Affiliated technical field
The utility model relates to a kind of navigation channel desilting instrument, specifically a kind of device of removing navigation channel mud.
Background technology
At present, along with expanding economy, the continually developing of coastal port, the more and more prosperity of ship industry, but coastal in the Yangtze river basin and port, the Changjiang river, it is bigger to contain quantity of sand and mud in the water, and a spring tide will stay one deck silt later, accumulate over a long period harbour and navigation channel obstruction are shoaled, have a strong impact on ship's navigation and entering and leaving port, harbour affairs department has to take dredge and dredges the way of completing and solve, but cost is very big like this, uneconomical, and between operational period, understand the entering and leaving port that influence other boats and ships.
Summary of the invention
In order to overcome the defective of the easy silting in navigation channel, the utility model provides a kind of Accrete clearing device, and this device not only can be removed original mud of navigation channel deposition, and makes that contained silt can sedimentation in the water.
The utility model solves the technical measures that its technical problem takes: make a call to a spud pile on the bottom mud face in navigation channel, connect a rope slightly at the end of stake, rope connects a ball float, and the height of ball float is below the depth of water more than needed.The other end of ball float connects the desilting rope.Hang some desilting sheets on the desilting rope, at the end of desilting rope slightly, connect a tail vane leaf, the tail vane leaf is made the hollow ellipse, can be suspended in the water.This Accrete clearing device is installed in current or the waters of tidal flow is arranged.When water flows, under the impact force of water flow effect, the desilting rope is under the swing of tail vane leaf, sweep away the mud face about meeting, the desilting sheet also can be under the effect of current, and the mud layer of the disturbance of rolling deposition is suspended in the water silt, along with current toward dirty and go, thereby reach the purpose of removing navigation channel bottom mud.
The beneficial effects of the utility model are: Accrete clearing device utilizes the power of flowing water, removes navigation channel mud, and is simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that a kind of Accrete clearing device is arranged in the schematic diagram on the mud layer.
Among the figure 1, stake, 2, ball float, 3, the desilting rope, 4, the desilting sheet, 5, the tail vane leaf.
The specific embodiment
In Fig. 1 king-pile (1) is beaten mud face at the navigation channel bottom, the end that ball float (2) connects stake (1) with rope slightly, (3) one in desilting rope connects ball float (2).The other end connects tail vane leaf (5).The desilting sheet is suspended on the centre of desilting rope.
Claims (2)
1, a kind of Accrete clearing device, stake is beaten in the mud of the bottom under water face of flow is arranged, the end that ball float connects stake slightly, the desilting rope connects ball float, at the end connection tail vane leaf of desilting rope, it is characterized in that: the desilting sheet is suspended on the desilting rope.
2, a kind of Accrete clearing device according to claim 1 is characterized in that: the tail vane leaf is made end that the hollow ellipse is connected the desilting rope slightly.
