Description

Automatic solar algae interception and collection device Technical Field The invention relates to the technical field of water ecological management, in particular to an automatic solar algae interception and collection device. Background Currently, aiming at the problem of algae burst (such as cyanobacteria bloom) in a large-area water area, common treatment means comprise manual salvage, ship collection, fixed enclosure interception and the like. The method has the defects of low efficiency, high energy consumption, large influence of wind and waves, strong interference on non-target aquatic organisms, difficulty in adapting to water flow change and the like. Particularly for scattered and drifting algae, the traditional rigid diversion structure is difficult to effectively converge, and the working stability is poor under the high turbulence or wave environment. In addition, the collected algae has high water content and high direct transportation and treatment cost. Therefore, a low-energy-consumption intelligent device which can adapt to water flow and stormy wave conditions, efficiently gather and collect surface algae and realize primary separation of algae and water is needed. Disclosure of Invention The invention aims to provide an automatic solar algae interception and collection device, which is characterized in that a diversion and collection module with a flexible flow field expansion assembly is arranged, and the passive self-adaptation characteristic of a flexible curtain is combined with active intelligent regulation and control to realize efficient, low-consumption, wide-area and strong-adaptability algae gathering and collection. In order to solve the technical problems, the invention specifically provides the following technical scheme: The utility model provides a solar energy algae automatic interception collection device, includes power module, intelligent control module, water conservancy diversion collection module and carries dehydration module, the water conservancy diversion collection module is equipped with the rigidity water conservancy diversion subassembly, the rigidity water conservancy diversion subassembly includes two pontoon formula water conservancy diversion arms of adjustable contained angle. The front end of the rigid flow guide component is designed into a V-shaped or U-shaped opening, and the opening and closing angle and the pitching angle can be adjusted in real time according to the water flow direction, algae distribution and operation modes (fixed, floating or shipborne movable). Especially when shipborne mobile operation, intelligent control module can be according to navigation speed and course, the dynamic adjustment water conservancy diversion arm contained angle makes it remain best windward angle all the time, ensure that the alga is effectively imported, and preferably, through the dynamic reduction or expansion contained angle, can initiatively adapt to different alga gathering density and distribution width, enlarge the blocking cross-section when the alga is sparse, shrink the runner in order to improve the imported velocity of flow when the alga is intensive, thereby reduce the stay and the lateral escape of alga in the entry region, promote mobile operation's collection efficiency. The flow guide collection module is also provided with a flexible flow field expansion assembly, the flexible flow field expansion assembly comprises at least one flexible curtain connected to the outer side of the rigid flow guide assembly, the bottom of the flexible curtain is provided with a counterweight, and the unfolding form of the flexible curtain is adjustable and is used for passively adapting and guiding water flow. When the water flow impacts the flexible curtain, distributed fluid pressure is applied to the surface of the curtain, and the flexible curtain can locally and continuously bend and deform in different areas by virtue of the characteristic of flexible materials, so that the flexible curtain can be automatically adjusted to a curved surface shape which is suitable for the current water flow state, and a stable configuration with minimum fluid resistance is achieved. The process completely depends on natural hydraulic driving, does not need external energy input, and belongs to a high-efficiency energy-saving passive adaptation mechanism. In the flow field shaping process, when the flexible curtain naturally forms a slightly convex relieving curved surface under the action of water flow, the water flow can smoothly deflect along the tangential direction of the water flow when contacting the curved surface of the curtain, so that streamline distribution converging towards the center of the device is generated. As the curvature change of the flexible curtain is smooth and continuous, the water flow speed is gradually reduced, and a stable low-flow-speed convergence area is formed. The floaters such as algae are stably and orderly enriched into the rigi
