Description

Technical Field

[0001] This utility model relates to environmental protection equipment for local water pollutant removal and ecological restoration, specifically a device for local water algae harvesting and aeration. Background Technology

[0002] In rivers, lakes, and reservoirs, especially in drinking water sources, the harmful effects of excessive algal growth on the ecological environment, human health, and socio-economic aspects are multi-dimensional, including the following: 1. Impact on aquatic ecosystems Oxygen depletion leads to a decrease in dissolved oxygen in water: The explosive growth of algae causes a surge in biomass, and nighttime respiration consumes a large amount of dissolved oxygen, leading to hypoxia in the water and threatening the survival of aquatic organisms. The decomposition process after the algae die further exacerbates oxygen consumption, causing "hypoxic zones" or "dead water zones" in the water, which can even cause fish and other organisms to suffocate and die in severe cases.

[0003] Shading damages aquatic environments: Dense algae on the surface block sunlight from penetrating the water, interfering with the photosynthesis of aquatic plants and even causing their death, thus affecting the food chain links that depend on these plants. At the same time, the water transparency decreases, severely diminishing its landscape value.

[0004] Disruption of the food chain balance: Dominant algal species crowd out the living space of other algae, altering the phytoplankton community structure and undermining the foundation of the food chain. Although some herbivorous organisms may obtain ample food in the short term due to algal overabundance, water quality deterioration and hypoxia will subsequently lead to mass mortality, ultimately disrupting the stability of the entire food chain.

[0005] Producing toxic and harmful substances: Some algae release algal toxins or odor-causing substances during metabolism. The former can poison aquatic organisms, causing them to grow slowly, have low reproductive capacity, or even die. The latter can cause the water to have an odor, endanger water quality, and reduce the sensory experience.

[0006] Water supply safety and potential health risks Drinking water safety is threatened: Algal blooms and the algal toxins they produce can contaminate drinking water sources. Conventional water treatment processes are insufficient to completely remove certain algal toxins, requiring additional investment and upgrades to treatment technologies. If treatment is inadequate, residual algal toxins in the water can cause acute or chronic poisoning if ingested, leading to symptoms such as liver damage, diarrhea, and vomiting. Long-term exposure may increase the risk of liver cancer.

[0007] Contact-related health impairment: When people engage in water activities such as swimming, playing in the water, and boating in waters where algal blooms occur, direct contact with the water or aerosols such as water mist from motorboats may irritate the skin, eyes, and respiratory tract, leading to allergic reactions or inflammation.

[0008] Food safety risks exist: Oysters, mussels, clams, and other shellfish, as well as fish, can accumulate algal toxins in their bodies. When people consume these contaminated aquatic products, these algal toxins can enter the human body through the food chain, potentially causing food poisoning. This is one of the main ways in which algal toxins harm human health.

[0009] Social and economic benefits The aquaculture sector is suffering setbacks: Algal blooms cause oxygen depletion and water quality deterioration in water bodies, leading to the mass mortality of aquatic animals such as fish, shrimp, and shellfish. Surviving aquatic products may also face unsaleable conditions due to excessive algal toxins. This double blow directly impacts the fishing and aquaculture industries, often resulting in significant economic losses.

[0010] The cultural and tourism value is diminished: Algal blooms cause unpleasant odors, discoloration, and marine death in water bodies, coupled with health risk warnings, which severely weaken the appeal of lake resorts and other attractions, leading to a sharp decline in visitor numbers and tourism revenue. Algal blooms in urban parks, lakes, and artificial waterways also detract from the city's appearance and negatively impact residents' daily lives.

[0011] The main causes of algal blooms include the following: 1. Eutrophication in water bodies provides the material basis for algae. When the levels of nutrients such as nitrogen and phosphorus in water exceed the standard, it provides ample "nutrients" for algae growth and reproduction. These nutrients meet the basic conditions required for algal growth and are an important material basis for algal blooms.

[0012] 2. Suitable light and temperature accelerate algal reproduction. Sufficient light (such as long days in summer) can effectively promote photosynthesis in algae, accelerate cell division, and promote rapid growth and reproduction. At the same time, under suitable temperature conditions, the physiological activities of algae become vigorous, and their growth and reproduction rate also accelerates, which provides favorable environmental conditions for algal blooms.

[0013] Suitable hydrological conditions are conducive to the aggregation and growth of algae. In relatively slow-moving aquatic environments, such as lakes and reservoirs where water exchange is poor, algae are not easily washed away and dispersed by the water flow, and are more likely to accumulate and grow. Such hydrological conditions provide a stable growth environment for algae, which is conducive to their large-scale reproduction and thus creates conditions for algal blooms.

[0014] Controlling algal blooms requires a multi-dimensional approach, addressing the root causes, including source intervention, environmental regulation, and direct treatment. Common techniques include: 1. Nutrient salt control technology By reducing the input of nutrients such as nitrogen and phosphorus into the water, the nutrient supply to algae can be reduced at its source.

[0015] Environmental control technology Interventions can be made to address environmental factors that affect algae growth, such as light, temperature, and hydrology. For example, increasing water flow can break up water stratification and prevent localized overheating. For slow-flowing water bodies, hydraulic engineering can improve hydrodynamic conditions, promote water exchange, and reduce algae accumulation.

[0016] Biological control technology Suppress algae growth by utilizing the natural laws of the ecosystem. For example, introduce filter-feeding fish to control algae levels through feeding; or inoculate beneficial microorganisms to inhibit algae reproduction through competition for nutrients or the secretion of algae-inhibiting substances.

[0017] Physical and chemical treatment technologies Physical methods include manually removing algae, using aeration equipment to increase dissolved oxygen in the water, and using technologies such as ultrasound or ultraviolet light to destroy the cell structure of algae. Chemical methods involve adding algicidal substances to quickly kill algae, under strict control of dosage. However, care must be taken to avoid secondary damage to aquatic organisms from the chemicals, and these methods are usually used as emergency treatments.

[0018] Currently, there are still significant technical shortcomings in the research on algal bloom control technologies. Existing control methods often focus on a single, independent step, such as mechanically removing algae or increasing dissolved oxygen in the water through aeration. There is a lack of synergistic mechanisms between these steps to improve overall effectiveness. In particular, few solutions integrate efficient algae removal, localized increases in dissolved oxygen levels, and enhanced water flow; a mature integrated management system encompassing all three has yet to be established.

[0019] This invention discloses a local water body algae harvesting and aeration device to simultaneously achieve efficient algae harvesting, increase dissolved oxygen content in local water areas, and restore the living environment of other organisms, thereby realizing comprehensive management of local water areas.

[0031] See attached diagram. A local water area algae harvesting and aeration device includes: a remotely controlled unmanned vessel hull, an algae harvesting section, and an aeration section.

[0032] The remote-controlled unmanned vessel hull includes: a parallel suspended hull 1-1, a power storage power supply 1-2, an equipment bracket 1-3, and a remote-controlled walking and control mechanism for the suspended body. The equipment bracket 1-3 is mounted on the suspended hull 1-1.

[0033] The algae harvesting section includes: an algae collection nozzle 2-1, an adjustable active swing arm 2-21, an adjustable passive swing arm 2-22, a swing arm control motor 2-3, a swing arm motor housing 2-4, an algae collection pump 2-5, an algae filter cartridge 2-6, and an oxygenation guide umbrella 2-7.

[0034] The algae collection nozzle 2-1 has an open conical front end, and its rear end is connected to the inlet pipe 2-51 of the algae collection pump 2-5. The algae collection nozzle 2-1 is rotatably connected to both the height-adjusting active swing arm 2-21 and the height-adjusting passive swing arm 2-22. The swing arm control motor 2-3 is sealed inside the swing arm motor housing 2-4. The swing arm motor housing 2-4 and the oxygenation guide umbrella 2-7 are fixed to the equipment bracket 1-3 within the remote-controlled unmanned vessel hull. The height adjustment active swing arm 2-21 is fixedly connected to the output shaft of the swing arm control motor 2-3 on the outside of the swing arm motor housing 2-4. The height adjustment passive swing arm 2-22 is rotatably connected to the outside of the swing arm motor housing 2-4. The swing arm control motor 2-3 is electrically connected to the power storage 1-2 in the remote-controlled unmanned vessel hull. The algae filter cartridge 2-6 is installed on the oxygenation guide umbrella plate 2-7. The water outlet pipe 2-52 of the algae collection pump 2-5 is installed inside the algae filter cartridge 2-6.

[0035] The aeration section includes: an aeration pump 3-1, an aeration pump housing 3-2, and an aeration head 3-3. The aeration pump 3-1 is sealed inside the aeration pump housing 3-2, which is fixed on the equipment bracket 1-3 in the remote-controlled unmanned vessel hull section. The aeration head 3-3 is connected to the air outlet of the aeration pump 3-1 via a pipeline, and the air inlet 3-11 of the aeration pump 3-1 is connected to the atmosphere.

[0036] When this utility model is in use, the remote-controlled unmanned vessel travels to the water area where algal blooms occur, and the algae collection pump 2-5 is turned on. As the remote-controlled unmanned vessel travels (such as the remote-controlled unmanned vessel traveling in a circular path around the water area where algal blooms occur) (forming a local vortex), the algae collection pump 2-5 draws the water containing algae into the algae collection nozzle 2-1 and pumps it into the algae filter cartridge 2-6. After the algae in the water are filtered out by the algae filter cartridge 2-6, the water flows back through the oxygenation guide umbrella plate 2-7, and the algae remain in the algae filter cartridge 2-6.

[0037] During the process of water flowing back through the oxygenation guide umbrellas 2-7, the water comes into contact with the air over a large area, increasing the oxygen content of the water and improving the dissolved oxygen content of the water body. At the same time, it increases the local circulation flow of the water body, which can effectively slow down the proliferation and accumulation of algae.

[0038] Based on the different aggregation patterns of dominant algal species, algal blooms can be divided into diffuse algal blooms and aggregated algal blooms. Diffuse algal blooms are typically characterized by the widespread distribution of algae in the water body. This invention, by adjusting the wading depth of the algae collection nozzle 2-1, can achieve the harvesting of algae widely distributed in the water body during a diffuse algal bloom outbreak. Simultaneously, the aeration pump 3-1 supplies oxygen to the local water area through the aeration head 3-3, changing the dissolved oxygen concentration in the local water area and improving the growth environment for other organisms.

[0039] After the algae are harvested, this invention can remain in the water for an extended period of time to aerate and oxygenate the local water area.

[0040] This invention uses a swing arm to control the motor 2-3, which drives the active swing arm 2-21 to adjust its swing angle, thereby adjusting the wading depth of the algae collection nozzle 2-1. In this embodiment, the algae collection nozzle 2-1, together with the active swing arm 2-21 and the passive swing arm 2-22, form a four-link algae collection nozzle 2-1 height adjustment mechanism, ensuring that the working posture of the algae collection nozzle 2-1 remains constant at different heights.

[0041] In this embodiment of the invention, a photovoltaic charging plate 2-8 is provided on the oxygen-enhancing guide umbrella plate 2-7, and the photovoltaic charging plate 2-8 is electrically connected to the energy storage power supply 1-2. The photovoltaic charging plate 2-8 charges the energy storage power supply 1-2, achieving the goals of energy saving, environmental protection, and increased working time.

[0042] In this embodiment of the invention, the front end of the algae collecting nozzle 2-1 is equipped with a water filter mesh 2-11, which performs preliminary filtration of the water entering the algae collecting nozzle 2-1, thereby increasing the efficiency of algae harvesting.

[0043] In this embodiment of the utility model, two sets of height-adjusting active swing rods 2-21 and height-adjusting passive swing rods 2-22 are provided. The swing rod control motor 2-3 is a dual-output shaft motor. Both output shafts of the swing rod control motor 2-3 are connected to the height-adjusting active swing rod 2-21, which increases the stability of the working posture of the algae collection nozzle 2-1.
