Description

Technical Field

[0001] This utility model relates to a cyanobacteria treatment system, specifically a cyanobacteria harvesting, collection, and flow stabilization system. Background Technology

[0002] Eutrophication of lakes is an international environmental problem, and it has become a particularly challenging aquatic ecological issue in China. Cyanobacterial blooms are a significant manifestation of this problem, making their control an urgent priority. Cyanobacterial harvesting, as the most direct, safe, and effective control method, has been widely adopted. Currently, commonly used methods include cyanobacterial harvesting vessels, algae removal platforms, and port-based centralized harvesting. These measures can alleviate the current situation of cyanobacterial accumulation in some lake areas and reduce the occurrence of secondary disasters. However, due to the uncertainty of cyanobacterial outbreaks, their occurrence and accumulation are difficult to predict. During peak periods, the capacity for cyanobacterial harvesting and disposal is insufficient; the utilization efficiency of harvesting vessels varies between different harvesting points; the existing cyanobacterial harvesting personnel are aging, have low levels of education, and their enthusiasm and safety during harvesting need improvement; the level of mechanization in harvesting needs to be increased, which to some extent increases the difficulty of harvesting. To address these shortcomings, our company has developed an AIO (Air-Independent, All-Weather, Intelligent, Offshore) intelligent cyanobacterial harvesting system. The entire system is set up on the lake surface at a certain distance from the shore. At the front end, a V-shaped interception device facing the lake surface has an algae suction pump at its pointed corner. Behind the V-shaped interception device is a long, narrow maintenance platform. The entire system floats on the lake surface. Blue-green algae brought by the wind are intercepted within the V-shaped structure. Through the stainless steel wave deflector above the floating pipe at the bottom of the V-shaped structure and the algae-blocking cloth that sinks to the lake bottom, it is ensured that most of the blue-green algae are blocked and collected within the V-shape. The algae suction pump sucks up the collected blue-green algae and flows through pipes into the algae water treatment facility for algae-water separation.

[0003] Placing the aforementioned AIO system on the lake surface to intercept cyanobacteria can efficiently collect and harvest them. However, during operation, it was found that when cyanobacterial blooms occur rapidly, it still cannot fully meet the needs for rapid and comprehensive harvesting. There are problems such as incomplete cyanobacteria interception and cyanobacteria remaining inside the harvesting system. At the same time, the device moves in the lake water, and some structural components require frequent inspection and maintenance, resulting in a large amount of maintenance work. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a highly efficient and intelligent blue-green algae capture, collection and flow stabilization system that can intercept and treat blue-green algae in all directions and efficiently by expanding the angle and area of ​​the interception and collection device, strengthening the structural strength, preventing secondary accumulation, enhancing the wind and wave resistance of the collection and dredging system, saving construction time, quickly putting the equipment into emergency use, and improving the efficiency of use.

[0005] Technical Solution: To solve the above-mentioned technical problems, the present invention provides a highly efficient and intelligent cyanobacteria harvesting, collection, and flow stabilization system. It includes a front-end algae interception and collection facility and a rear-end algae-blocking and flow stabilization facility, with a distance between them. Both the main body of the algae interception and collection facility and the main body of the algae-blocking and flow stabilization facility are assembled from modules connected by connectors. The algae interception and collection facility includes a continuous V-shaped or arc-shaped interception device and an algae-absorbing device. Both the front-end algae interception and collection facility and the rear-end algae-blocking and flow stabilization facility float on the lake surface and are connected by steel cables via steel piles driven into the lakebed. Cyanobacteria in the lake water are collected by the V-shaped or arc-shaped interception device facing the lake surface. The algae-absorbing device transports the high-concentration algae-infused water to an algae-water separation facility for separation and resource utilization. The rear-end algae-blocking and flow stabilization facility further prevents the cyanobacteria in the lake water from flowing towards the lake shore, while simultaneously stabilizing the water flow and preventing waves from impacting the inner lake shore.

[0006] Furthermore, the bottom of the module consists of two hollow HDPE or alloy pipes forming a float, which is circular or rectangular in shape. The float is made of steel to form an overall frame, and the frame is equipped with reinforcement components. Wave-blocking plates are installed along the lower part of the HDPE or alloy pipes. The wave-blocking plates are covered with an algae-blocking cloth that extends to the lake bottom. The algae-blocking cloth hangs down to the lake bottom, which can effectively prevent blue-green algae broken by wind and waves from flowing into the shore from the lower part of the interception device. The main body of the front algae water interception and collection facility and the main body of the rear algae blocking and flow stabilization facility can be arbitrarily and quickly connected along the installation direction according to the length requirements.

[0007] Furthermore, an algae-absorbing device is installed at the angle of the continuous V-shaped or arc-shaped interception device. A grid screen is installed in front of the algae-absorbing device to block debris in the water. There are two grid screens. The first guide grid screen is connected to the frame at both ends and stands in the water. The first guide grid screen is staggered. Lake water and blue-green algae flow from the middle gaps to the angle. Larger debris in the water is intercepted first. At the same time, because the front end of the first guide grid screen is sharp, it has a guiding function. The second grid screen is close to the algae-absorbing pump. The gaps between the grids are smaller than those at the front end. It is used to intercept smaller debris in the water and prevent blockage of the algae-absorbing pump in the algae-absorbing device.

[0008] Furthermore, an algae concentration detector is installed at the angle of the continuous V-shaped or arc-shaped interception device, which floats as a whole in the lake water along with the front-end algae interception and collection facility, and the algae suction pump automatically starts and stops according to the detected algae concentration.

[0009] Furthermore, each V-shaped or arc-shaped interception device is equipped with algae-pushing and diversion pumps on both sides inside. The outlets of the algae-pushing and diversion pumps on both sides are arranged facing each other. The outlet water flow accelerates the algae water towards the grid screen and finally flows towards the algae suction device.

[0010] Furthermore, a mobile algae suction device is installed between the front-end algae water interception and collection facility and the back-end algae blocking and flow stabilization facility to draw out the algae water trapped between the two and pump it to the main algae transport pipe.

[0011] Furthermore, the algae transport main is submerged to the bottom of the lake after being weighted by counterweights. The algae transport main is made of UV-resistant HDPE or stainless steel.

[0012] Furthermore, the main algae transport pipe is connected to the algae suction device at the included angle inside the continuous V-shaped or arc-shaped interception device via branch pipes, and telescopic hoses are installed at both ends of the branch pipes.

[0013] Furthermore, the algae transport main pipe can also be installed on the platform of the back-end algae blocking and flow stabilization facility, and the outlet of the algae suction device is connected to the algae transport main pipe through a flexible hose.

[0014] Furthermore, the modules in the algae blocking and flow stabilizing facility are pressed together by pressure plates to prevent the water flow from deviating, and vibration damping buffer devices are installed between the pressure plates.

[0015] In this invention, an appropriate gap can be maintained between the front-end algae interception and collection facility and the rear-end algae-blocking and flow-stabilizing facility. Furthermore, the gap can be adjusted according to the amount of blue-green algae remaining on the lake surface. Connecting channels are provided at both ends of the rear-end algae-blocking and flow-stabilizing facility to the lake shore, forming a relatively enclosed lake area within these channels.

[0016] The V-shaped or arc-shaped interception device is assembled from standard modules. The bottom of each module consists of two hollow HDPE or alloy pipes, either circular or rectangular. The two parallel pipes are connected by a steel frame. The top surface of the module frame is covered with galvanized mesh or wood-plastic composite flooring. After the two parallel hollow pipes are connected, an algae-blocking plate is installed along the length of the lower part. A permeable algae-blocking cloth hangs from the bottom of the algae-blocking plate, extending to the lake bottom. A heavy steel chain hangs from the bottom of the cloth, effectively preventing blue-green algae broken by wind and waves from flowing into the shore from the bottom of the interception device. An intelligent algae-absorbing device is installed at the pointed angle of the continuous V-shaped or arc-shaped interception device. The high-concentration algae-infused water drawn by the device is connected to the algae-water separation facility through an algae-water delivery pipe. The rear algae-blocking and flow-stabilizing facility also consists of multiple standard modules. Permeable algae-blocking cloth is also hung from the bottom of the two parallel hollow pipes, forming another algae-blocking and wave-blocking barrier. There is a certain distance between the front-end interception and collection facilities and the rear-end dike protection and flow stabilization facilities. Both the front-end interception and collection facilities and the rear-end dike protection and flow stabilization facilities are connected to steel piles that extend deep into the lake bottom via steel cables.

[0017] The V-shaped or arc-shaped interception device has two grid nets at the front end, with both ends of the grid nets connected to the interception device and facing the water surface. Larger debris in the lake water, such as tree branches, is intercepted, and the algae-absorbing water flows to the intelligent algae-absorbing device at the angle.

[0018] The first layer of protective mesh is made of steel profiles, with the front ends of the steel profiles forming sharp corners facing the lake surface.

[0019] A second grid screen is installed at the front end of the algae suction pump to block small debris in the algae water and prevent clogging of the pump's suction port.

[0020] A high-definition camera and an online algae concentration analyzer are installed at the corner of the V-shaped or arc-shaped interception device. Operators can control the start and stop of the algae suction pump through intuitive visual or algae density data analysis.

[0021] The V-shaped or arc-shaped interception device is equipped with algae-pushing and diversion pumps on both sides. When too much blue-green algae accumulates in the water, a high-pressure water jet rushes into the algae-infused water inside the interception device, causing the algae-infused water to flow quickly to the algae-absorbing pump.

[0022] The algae suction pump can automatically open or close based on the cyanobacteria concentration signal. At the same time, its height can be adjusted along the sliding grooves on both sides of the algae suction device, and it can be interlocked with the algae pushing and guiding pump to ensure rapid and efficient suction of cyanobacteria.

[0023] The algae-absorbing pump automatically draws in algae water, which is then transported to the algae-water separation facility through the main algae transport pipe set between the V-shaped or arc-shaped interception device and the downstream dike flow stabilization facility. The algae transport pipe is either submerged on the lake bottom or erected on the algae-blocking and flow stabilization facility platform by a counterweight. The algae transport pipe is made of UV-resistant HDPE material, and the diameter of the main algae transport pipe gradually increases from the front end to the rear end according to the algae water flow rate.

[0024] The bottom of the rear algae-blocking and flow-stabilizing module consists of hollow HDPE or alloy pipes, in the form of circular or rectangular pontoons. Two parallel pontoons are connected by structural steel. Algae-blocking plates are installed at the bottom of the pontoons, with permeable algae-blocking fabric hanging below them. A steel chain is suspended at the bottom of the fabric, further preventing algae from entering the inner lake.

[0025] The back-end algae-blocking and flow-stabilizing facility consists of multiple standardized algae-blocking and flow-stabilizing modules, which are assembled and connected along the length. To prevent the platform from moving irregularly due to the surge of lake water, adjacent algae-blocking and flow-stabilizing modules are pressed together with steel in an alternating manner. At the same time, to reduce friction and collision between adjacent embankment flow-stabilizing modules, a pressure buffer device is installed between the two platforms to reduce wear at the module connection.

[0026] A mobile algae-absorbing device is installed between the front-end interception and collection facility and the back-end algae-blocking and flow-stabilizing facility to quickly clean up the algae-laden water brought into the space between them by the wind.

[0027] Beneficial Effects: Compared with existing technologies, the significant advantages of this invention are as follows: Compared to previous intelligent cyanobacteria harvesting and interception systems, the V-shaped or arc-shaped interception device of this invention is composed of standard modules. Each module consists of two ultraviolet-resistant HDPE pipes, stainless steel pipes, or alloy pipes forming a bottom pontoon. The pontoons are connected by steel sections, and galvanized mesh or plastic wood panels are laid on the steel sections to form a maintenance and operation channel. Addressing the issue of weak wind and wave resistance in the original V-shaped system, which consisted of single pontoons connected to form the sides, this invention increases the angle of the V-shaped or arc-shaped structure facing the lake surface and extends its length towards the lake surface. This allows it to adapt to different wind directions in cyanobacteria harvesting, achieving comprehensive and efficient cyanobacteria collection and effectively enhancing the wind and wave resistance and service life of the V-shaped or arc-shaped interception device.

[0028] This utility model's V-shaped or arc-shaped interception device features two interception nets facing the lake surface. The first net, formed by a steel structure, acts as a flow guide grille to remove larger debris from the water and prevent it from impacting the device's floats. The sharp corners of the first flow guide grille are positioned towards the lake surface, ensuring a rational structure and guiding the water flow inwards. The second net blocks smaller debris, ensuring the efficient operation of the algae suction pump.

[0029] The interception and collection facility and the algae blocking and flow stabilization facility of this utility model are spaced apart. The distance between the two can be adjusted by adjusting the length of the connecting steel cable. After the algae water flows in with the wind, the algae-flushing pump and the mobile algae suction device set in the middle quickly clean up the stagnant algae water.

[0030] The V-shaped or arc-shaped interception device of this utility model has an algae suction pump at its tail that automatically starts and stops based on the collected algae concentration, enabling all-weather, intelligent operation.

[0031] In addition to using clamping plates to compact the algae-blocking and flow-stabilizing standardized modules to form a whole, vibration damping and buffering devices are added at the connection points of the algae-blocking and flow-stabilizing standardized modules to reduce wear at the module connection points.

[0032] The algae transport pipe of this invention is submerged in the lake bottom by a counterweight, which facilitates smooth water flow between the V-shaped or arc-shaped interception device and the algae-blocking and flow-stabilizing platform.

[0033] Because the intelligent cyanobacteria harvesting and dehydration system has altered the structural strength of its front-end interception and collection facilities and its rear-end algae-blocking and flow-stabilizing system, it is resistant to wind and wave impacts. The bottom of each system has algae-blocking cloth that sinks to the lake bottom, effectively intercepting cyanobacteria. At the same time, the system has a significant effect on protecting the dike and stabilizing the flow. Not only is there no cyanobacteria inside the algae-blocking and flow-stabilizing system, but the water flow is also stable, which plays a very good role in protecting the dike. This area is suitable for planting aquatic plants and creating a beautiful environment.

[0034] The bottom of the front-end interception and collection system and the rear-end algae-blocking and flow-stabilizing system of this invention is composed of bottom floats made of UV-resistant HDPE pipes, stainless steel pipes, or alloy pipes, which float freely with the rise and fall of the water level. Both the front-end interception and collection system and the rear-end algae-blocking and flow-stabilizing system are standardized modular combinations. After the standardized modules of the collection system and the algae-blocking and flow-stabilizing system are assembled, they naturally form a maintenance and operation platform passage.

The algae interception and collection facility faces the lake surface. The V-shaped or arc-shaped interception device 1 is located inside the algae-blocking and flow-stabilizing facility 2, with an appropriate gap in the middle. It is connected and fixed by steel piles 7 driven into the water and steel cables. Both the algae interception and collection facility and the dike flow-stabilizing system are composed of two layers of ultraviolet-resistant HDPE pipes, stainless steel pipes, or alloy pipes forming bottom floats 9, which are connected by steel sections. The algae-absorbing device 3 is installed at the tip of the V-shaped or arc-shaped interception device 1. Two grid screens are installed in front of the algae-absorbing pump device. The first guide grid is composed of steel sections. The two ends of the grid screen are connected to the inside of the V-shaped or arc-shaped interception device 1, with an appropriate gap to intercept larger debris such as tree branches in the water. The steel structure forms a sharp corner facing the water surface, guiding the algae-infested water to the inward side. The second grid screen is installed in front of the algae-absorbing pump device to further remove smaller debris from the lake water. The algae-infused water, after being blocked of debris, is pumped by the algae-absorbing pump to the algae transport main pipe 16 and then sent to the algae-water separation facility. An algae-flushing pump 4 is installed inside the V-shaped or arc-shaped algae interception and collection device, located in front of the first grid screen. Its function is to accelerate the pushing of high-concentration algae-infused water towards the algae-absorbing device 3 at the top of the V-shaped or arc-shaped interception device. The algae-flushing pump and the algae-absorbing pump are interlocked for operation.

[0038] The algae transport main pipe 16 is made of HDPE or stainless steel and is submerged to the bottom of the lake via a counterweight 17.

[0039] V-shaped or arc-shaped cyanobacteria interception and collection facilities and algae-blocking and flow-stabilizing facilities consist of standardized modules composed of two parallel underwater pontoons. Wave-blocking plates 13 are installed along the length of the modules. Each wave-blocking plate 13 is bolted to a baffle cloth 14. The baffle cloth 14 hangs to the bottom of the lake, which can effectively prevent cyanobacteria broken by wind and waves from flowing into the shore from the bottom of the interception device.

[0040] The wave deflector 13 is made of stainless steel or organic materials.

[0041] The algae-blocking fabric 14 is made of nylon, which features high density, wear and corrosion resistance, and good water permeability. Blue-green algae are blocked on the outside of the fabric, and water flows through the gaps in the fabric towards the lake shore.

[0042] An appropriate gap is left between the V-shaped or arc-shaped cyanobacteria interception and collection facilities and the algae blocking and flow stabilization facilities. A mobile algae suction device 8 is installed in the gap to remove the algae-laden water.

[0044] The two ends of the algae-blocking and flow-stabilizing facility are connected to the lake shore by connecting channels 15, forming a relatively enclosed lake area within the connecting channels 15.

[0045] The operation process of this utility model is as follows: A V-shaped or arc-shaped cyanobacteria interception and collection facility, composed of standardized modules, and a dike protection and flow stabilization system are installed on the lake surface. The V-shaped or arc-shaped cyanobacteria interception and collection facility faces the lake surface to collect and intercept algae-laden water. The algae-laden water is drawn in by the wind and converges inside the facility. An algae-suction pump located at the tip of the V-shaped or arc-shaped interception device automatically activates based on collected signals, and an algae-water diversion pump also starts simultaneously, pushing the algae-laden water towards the suction pump. After suction, the water is transported through an algae-transporting pipeline to an algae-water separation facility for dehydration and separation. Both the cyanobacteria interception and collection facility and the algae-blocking and flow stabilization system are equipped with wave-breaking plates at the top and two algae-blocking barriers at the bottom. The algae-blocking and flow stabilization system is located behind the V-shaped or arc-shaped cyanobacteria interception and collection facility. The two systems form a barrier to collect algae-laden water, efficiently and intelligently capturing and completely blocking cyanobacteria from the system. The lake flow inside the algae-blocking and flow stabilization system is stable and can be used for water body restoration or landscape engineering. Example 2

The steel structure forms a sharp corner facing the water surface, guiding the algae-infested water to the inward side. The second grid screen is installed in front of the algae-absorbing pump device to further remove smaller debris from the lake water. The algae-infused water, after being blocked of debris, is pumped by the algae-absorbing pump to the algae transport main pipe 16 and then sent to the algae-water separation facility.

Its function is to accelerate the pushing of high-concentration algae-infused water towards the algae-absorbing device 3 at the top of the V-shaped or arc-shaped interception device. The algae-flushing pump and the algae-absorbing pump are interlocked for operation.

[0047] The main algae transport pipe 16 is installed on the algae blocking and flow stabilization facility platform, and its diameter gradually increases from the front end to the rear end.

[0048] V-shaped or arc-shaped cyanobacteria interception and collection facilities and algae-blocking and flow-stabilizing facilities consist of standardized modules composed of two parallel underwater pontoons. Wave-blocking plates 13 are installed along the length of the modules. Each wave-blocking plate 13 is bolted to a baffle cloth 14. The baffle cloth 14 hangs to the bottom of the lake, which can effectively prevent cyanobacteria broken by wind and waves from flowing into the shore from the bottom of the interception device.

[0049] The wave deflector 13 is made of stainless steel or organic materials.

[0050] The algae-blocking fabric 14 is made of nylon, which features high density, wear and corrosion resistance, and good water permeability. Blue-green algae are blocked on the outside of the fabric, and water flows through the gaps in the fabric towards the lake shore.

[0051] An appropriate gap is left between the V-shaped or arc-shaped cyanobacteria interception and collection facilities and the algae blocking and flow stabilization facilities. A mobile algae suction device 8 is installed in the gap to remove the algae-laden water.

[0052] The standard modules in the algae blocking and flow stabilizing facility are pressed together by pressure plates 18 to prevent water flow from deviating. Vibration damping and buffer devices 19 are installed between the pressure plates 18 to reduce friction and reduce equipment wear.

[0053] The two ends of the algae-blocking and flow-stabilizing facility are connected to the lake shore by connecting channels 15, forming a relatively enclosed lake area within the connecting channels 15.

[0054] This utility model's V-shaped or arc-shaped interception device consists of standard modules. Each module comprises a bottom pontoon made of two UV-resistant HDPE, stainless steel, or alloy pipes. The pontoons are connected by steel sections, on which galvanized mesh or plastic-plastic panels are laid to form a maintenance and operation channel. Addressing the issue of weak wind and wave resistance in traditional V-shaped devices with single pontoons connecting the sides, this new design increases the angle of the V-shaped or arc-shaped structure facing the lake surface and extends its length towards the lake. This adapts to different wind directions, enabling comprehensive and efficient algae collection and effectively enhancing the wind and wave resistance and lifespan of the V-shaped or arc-shaped interception device.

[0055] This utility model's V-shaped or arc-shaped interception device features two interception nets facing the lake surface.

[0057] This utility model's interception and collection facility features a V-shaped or arc-shaped interception device with an algae-suction pump at the tail, which automatically starts and stops based on the collected algae concentration, achieving all-weather, intelligent operation. In addition to using clamping plates to solidify the standardized algae-blocking and flow-stabilizing modules, vibration-damping buffer devices are added at the connection points to reduce wear. The algae-transporting pipe is submerged at the lake bottom with counterweights, facilitating smooth water flow between the V-shaped or arc-shaped interception device and the algae-blocking and flow-stabilizing platform. Due to the modified structural strength of the front-end interception and collection facility and the rear-end algae-blocking and flow-stabilizing system of the intelligent blue-green algae harvesting and dehydration system, both are resistant to wind and wave impacts. Algae-blocking cloth is lowered to the lake bottom at both ends, effectively intercepting blue-green algae. Simultaneously, the system provides significant dike protection and flow stabilization; the inner side of the algae-blocking and flow-stabilizing system is free of blue-green algae, and the water flow is stable, effectively protecting the dike.
