Problems solved by technology
In addition, in the case of winter and strong wind and waves, the conventional enclosure lacks self-regulation ability, and the floating body part always floats on the water surface, which has been damaged by wind, wave and ultraviolet radiation for a long time, shortening the service life of the enclosure

Embodiment Construction
[0018] see Figure 9 , 10 , the single floating barrel is a cylindrical barrel with both ends closed, and the left and right end faces are arranged in a symmetrical wedge shape 7, lying on the water surface. The wedge-shaped center plane is the longitudinal center plane of the cylindrical barrel. Two air nozzles 4 are arranged symmetrically on the upper surface of the floating bucket. On the inside of the tip top, one end of all gas nozzles is connected with their respective bucket chambers. At the midpoint of the lower surface of the opposite side of the floating bucket gas nozzle, there is a water hole 5 connected with the bucket cavity. In the natural state, the water hole is always closed. Under water, there are symmetrical counterweights 2 fixed to the inner wall of the floating bucket on the left and right sides of the water hole 5; a frame-shaped flange 3 fixedly connected to the outer wall of the floating bucket is arranged around the outer periphery of the floating b...

The invention relates to a floating type soft barricading used for a lake water protection area. A floating body chain is formed by serially connecting a plurality of floating barrels through a flexible drape; the floating barrels are cylindrical and are arranged in a horizontal form, the left end surface and the right end surface form two symmetrical wedges, and the center planes of the wedges are the longitudinal center planes of the cylindrical barrels; the upper surface of each floating barrel is provided with two symmetrically arranged air nipples; the air nipples are positioned on the center planes of the wedges and are close to the inner sides of the two wedges; one end of each air nipple is communicated with respective barrel cavity, the other ends of all the air nipples are communicated with a hose, both ports of the hose are respectively communicated with two ports of a tee joint, another port of the tee joint is communicated with one port of another tee joint through a hose, and the other two ports of the tee joint are respectively communicated with atmosphere and compressed air through valves; the center point of the lower surface dead against the air nipple of each floating barrel is provided with a water hole for communicating with the barrel cavities; and two symmetrical balancing weights are arranged at the left side and the right side of the water hole, and the external periphery of the floating barrels is provided with a frame-shaped flange for connecting the drape and the hose.
Description
technical field [0001] The invention relates to enclosures for intercepting algae and transporting polluted water bodies to protection areas, in particular to a sinking-floating soft enclosure for lake water protection areas, which belongs to the technical field of water environment treatment. Background technique [0002] At present, the frequency of algae blooms in domestic lake water source areas is increasing year by year, resulting in increased pressure on the degradation of aquatic plants in water source areas. Once aquatic plants disappear, it will have an extremely adverse impact on the entire ecosystem. Therefore, there is an urgent need to protect the water area of the water source area, control the harm of algae blooms to the water source area, and prevent the degradation of aquatic plants in the water source area; It has always been an important issue concerned by relevant institutions. Although the commonly used soft enclosure algae barrier device can interce...
