Embodiment 1
[0032] see figure 1 , a river-type reservoir algae control device, which includes a water-proof curtain 1, the bottom of the water-proof curtain 1 is connected to a fixed pier 2 through a plurality of connecting cables 4, the fixed pier 2 sinks at the bottom of the water, and the water-proof A buoy 3 is connected to the top of the screen 1, and the buoy 3 stretches the water-proof screen 1 and makes it completely submerged below the water surface. By using the above-mentioned algae control device, the layout of the device greatly reduces the flow rate of the upper water body that is rich in nutrients, and the algae proliferates rapidly in this water area, consuming a large amount of nutrients in the upper water body, and the remaining nutrients play a role in the device. Under the water flow, it guides the lower layer of dark and low water temperature where algae are difficult to grow, so that it can inhibit the growth of algae within a certain distance.

Embodiment 2
[0042] The algae control method of any river type reservoir algae control device, it comprises the following steps:
[0043] Step1: Select the appropriate size, installation quantity and specific location of the water barrier curtain 1 according to the specific river channel type, water flow conditions and occurrence of algal blooms;
[0044] Step2: Use the determined size of the waterproof curtain 1 to determine the weight of the fixed pier 2 through mechanical analysis and calculation of the device structure;
[0045] Step3: Connect multiple fixed piers 2 and water-proof curtain 1 through connecting cables 4. The overall height of the device is the water depth of the layout point. When multiple fixed piers 2 sink to the bottom of the water, it also drives the water-proof curtain 1 to sink. into the water;
[0046] Step4: The top of the water-proof curtain 1 is close to the water surface, and after the water-proof curtain 1 is stabilized, fix the buoy 3 on the water-proof cu...
Embodiment 3
[0050] The water velocity is 0.1m / s, and the concrete density is 2.4×10 3 kg / m3, the length of the waterproof curtain is 50m, the height is 3m, and the thickness is 0.001m. After calculation, the weight of each fixed pier is 20kg.
