In order to make the interception head 6 can be abundant collect the pollutant that gathers the face of gathering to make the interception efficiency of pollutant higher, so, preferably, along the rivers flow direction, the interception head 6 sets up the central zone at the face of gathering of interception frame 5, the bottom edge lateral wall of interception head 6 is equipped with gets into square hole 8, and interception head 6 is equipped with the imbibition head that can float in the surface of water and aspirate liquid, imbibition head includes counter weight section 9 and suction section 10 of sliding connection in interception head 6, suction section 10 sets up at counter weight section 9 top, counter weight section 9 can take suction section 10 along interception head 6 inner wall subsidence until the work head on suction section 10 flushes with the surface of water.
Specifically, the converging surface in the present invention is preferably arc-shaped, and may be other shapes, as long as the purpose of converging the pollutants entering the energy dissipation channel 4 is satisfied.
After the separation bag strip 2 is installed, the separation bag strip 2, the interception frame 5 and the energy dissipation baffle 3 can be fixed through ropes (hooks for fixing the ropes are arranged on the separation bag strip 2, the interception frame 5 and the energy dissipation baffle 3), and finally, the fixed state can be referred to fig. 1 and 2.
After the installation of all components is finished, the water flow flowing along the river can be separated by the separation bag strip 2 to form a plurality of energy dissipation flow channels 4, so that a large water flow is separated into a plurality of small water flows, then the small water flows entering the energy dissipation flow channels 4 are subjected to speed limiting operation from the water flow by the energy dissipation baffle 3, the water flow is prevented from rapidly taking away pollutants, and then the pollutants on the water surface flow to the interception frame 5 along with the water flow.
At this time, the water flow floats up the counterweight section 9, so that the working head on the suction section 10 is flush with the water surface, then, the liquid pumping device such as the vacuum pump is started, and the pollutants on the water surface can enter the working head on the suction section 10 through the square hole 8 and are pumped into the vacuum pump through the hose.
In the invention, the liquid suction head is arranged in the blocking head 6, so that the liquid suction head can be limited, the liquid suction head is prevented from shaking randomly, and meanwhile, sundries can be prevented from blocking the liquid suction head.
In order to achieve the collection of the contaminants, an embodiment is therefore provided for the interception frame 5 so that the intercepted contaminants do not all accumulate in the area of the converging surface.
The interception frame 5 includes floating in the support body 11 of surface of water, and the support body 11 is located the energy dissipation runner 4, and the face setting that gathers is equipped with in the support body 11 towards the one side of rivers flow direction, holds the chamber in the support body 11, holds the intracavity and is equipped with the liquid storage bag 12, and the liquid that holds liquid storage bag 12 can receive the suction of liquid suction head, and the bottom of support body 11 is equipped with and holds liquid storage bag 12 fixed connection's sealing up board 13, sealing up board 13 is located the underwater part and can push up to hold liquid storage bag 12 and get into the chamber, and the top of support body 11 is equipped with the isolation board 30.
After the pollutants are pumped into the vacuum pump and other devices, the pollutants can be directly introduced into the accommodating cavity through the hose, then as the pollutants entering the accommodating cavity are increased, the sealing plate 13 can sink into water, and in the sinking process of the sealing plate 13, the liquid storage bag 12 can be gradually straightened (before the liquid storage bag 12 is not straightened, the liquid storage bag is placed in the accommodating cavity), so that the accommodating cavity can store more pollutants.
In this embodiment, the air holes may be formed on the isolation board 30, so that the accommodating cavity will not be inflated when the vacuum pump is empty, and meanwhile, the water pipe connected to the shore may be installed at the bottom of the sealing board 13, so that the pollutant in the accommodating cavity may be pumped to the shore all the time to prevent the situation that the existing liquid bag 12 is fully loaded and turned over.
