Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment, and more specifically, to a lake water quality restoration device and method. Background Technology

[0002] The bottom of lakes and reservoirs is in an oxygen-deficient environment for extended periods, making it impossible for most benthic animals to survive. One reason for this oxygen deficiency is the stratification of water temperature, which prevents the exchange of dissolved oxygen between the upper and lower layers. Another reason is that the bottom is often in a dark zone, depriving it of the source of oxygen produced by the photosynthesis of submerged plants and epiphytic algae.

[0003] The bottom of lakes and reservoirs is deposited with large amounts of organic matter, the decomposition of which consumes a significant amount of oxygen. During periods of water stratification, communication between the upper and lower water layers is difficult, and the abundant dissolved oxygen in the upper layer cannot be readily exchanged to the lower layers, often resulting in anoxic conditions at the bottom of these lakes and reservoirs. As the organic matter in the bottom sediment continues to decompose, dissolved oxygen consumption increases, eventually leading to the depletion of dissolved oxygen at the bottom of the lake or reservoir. Dissolved oxygen is essential for the survival of benthic animals, and given their limited migratory abilities, many benthic animals cannot survive for extended periods without oxygen, and even species that are relatively tolerant of low oxygen levels cannot survive indefinitely.

[0004] The second source of oxygen at the bottom of lakes and reservoirs is the oxygen produced by the photosynthesis of submerged plants and epiphytic algae. However, this oxygen production is entirely dependent on sunlight, which decreases with increasing depth. Below the light-transmitting zone, the light intensity is insufficient to produce net photosynthesis and release oxygen. In deep reservoirs, sunlight cannot reach the bottom. Even in shallow lakes and reservoirs, due to the generally low transparency of eutrophic water, sunlight struggles to reach the bottom. Not only do large submerged plants disappear, but even epiphytic algae that can photosynthesize in extremely low light conditions find it difficult to survive, further exacerbating the severity of oxygen depletion at the bottom of lakes and reservoirs.

[0005] Therefore, to restore benthic animal communities, it is essential to improve the long-term oxygen-deficient environment at the bottom of lakes and reservoirs. Based on the above analysis, there are two ways to improve the oxygen-deficient situation at the bottom of lakes and reservoirs: First, significantly increase water transparency so that sunlight can reach the bottom, meeting the conditions for photosynthesis of submerged plants and epiphytic algae, thus restoring submerged plant vegetation or allowing epiphytic algae to produce oxygen through photosynthesis; Second, break up water temperature stratification to promote exchange between the upper and lower water layers, allowing oxygen-rich water from the upper layer to be exchanged to the bottom layer in a timely manner.

[0006] The first approach, which is the common path taken in the ecological restoration of eutrophic lakes and reservoirs, is to try to increase transparency so that sunlight can reach the bottom layer and thus restore submerged plants on a large scale. Practice has proven that this approach is not feasible.

[0007] Therefore, a feasible solution to improve the dissolved oxygen levels at the bottom of eutrophic lakes and reservoirs, thereby restoring benthic animal communities, is to break up the water temperature stratification and promote the exchange between the upper and lower water bodies, so that the oxygen-rich water in the upper layer can be exchanged to the bottom layer in a timely manner.

[0008] Specifically, on sunny afternoons, mechanical methods are used to promote water exchange between upper and lower water layers, allowing oxygen-rich or supersaturated water from the upper layer to be transferred to the lower layer, ensuring sufficient dissolved oxygen. Once the oxygen deficiency at the bottom is broken, the organic matter deposited at the bottom of the eutrophic lake becomes a continuous source of nutrients for benthic animals. The more organic matter deposited, the richer the benthic animal community becomes, thus eutrophication promotes the abundance of benthic animal communities. Currently, there is a lack of equipment that can facilitate water layer exchange and nutrient transfer while in motion, such as on a boat, to ensure sufficient dissolved oxygen at the bottom.

The central shaft of the propeller is fixedly connected to the L-axis, and the circular shaft of the L-axis is set in the driven slot. Cross blocks are respectively set in the symmetrical cross slots. The symmetrical cross blocks are respectively fixedly connected to the power shafts. The symmetrical power shafts are respectively set in the corresponding driven slots. The symmetrical cross blocks are respectively fixedly connected to the guide cylinders. The symmetrical guide cylinders are respectively provided with moving rods. The symmetrical moving rods are respectively rotatably connected to the water layer exchange component. The water layer exchange component includes symmetrical loop blocks. The symmetrical moving rods are respectively rotatably connected to the corresponding loop blocks. The symmetrical arc tracks pass through the corresponding loop blocks. The symmetrical loop blocks are respectively fixedly connected to the fixing frames. The symmetrical fixing frames are respectively fixedly connected to the water pipes.

[0012] As a further limitation of this technical solution, the base plate is fixedly connected to symmetrical vertical rods, and the symmetrical vertical rods are respectively rotatably connected to auxiliary components. The auxiliary components include symmetrical wing plates, the symmetrical vertical rods are respectively rotatably connected to the corresponding wing plates, and the symmetrical wing plates are respectively fixedly connected to U-shaped slots.

[0013] As a further limitation of this technical solution, the T-shaped rod is fixedly connected to symmetrical mounting round rods, and the symmetrical mounting round rods are respectively fixedly connected to power balls, and the symmetrical power balls are respectively set in the corresponding U-shaped slots.

[0014] As a further limitation of this technical solution, the upper connecting plate is fixedly connected to the buoyancy assembly, the buoyancy assembly includes a buoyancy chamber, the upper connecting plate is fixedly connected to the buoyancy chamber, the symmetrical vertical rods are respectively fixedly connected to the buoyancy chamber, the buoyancy chamber is fixedly connected to the mounting block, the upper side of the buoyancy chamber is fixedly connected to the connecting joint, and the lower part of the buoyancy chamber is fixedly connected to the drain valve.

[0015] As a further limitation of this technical solution, a one-way valve is provided inside the connector.

[0016] As a further limitation of this technical solution, the wing plate is made of non-metallic material.

[0017] As a further limitation of this technical solution, the base plate is made of solid metal material.

[0018] A method for restoring lake water quality using a remediation device, characterized by comprising the following steps:

[0019] S1: Connect the mounting block to the boat with an iron chain, and connect one end of a hose to the fixing frame and the other end to the vertical plate to achieve communication between the inlet and the corresponding water pipe;

[0020] S2: Operate the boat to move the device in the lake, and add water to the buoyancy chamber through the joint to make the device stand at a suitable height from the lake bottom;

[0021] S3: The vessel is moved on the water surface, causing the water flow to impact the propeller, thus achieving water layer mixing. The water flows through the inlet into the water pipe and is discharged from the water pipe to different water layers, achieving oxygen exchange.

[0022] S4: The wing plate swings back and forth, enabling the equipment to move forward stably while the water flows up and down.

By compressing air into it, combined with the drain valve below and the high-density alloy weight at the bottom of the base plate, the center of gravity is adjusted to suit various water densities. This allows for the adjustment of the device's position in the water, facilitating its entry into water temperature stratification zones. After air is compressed into the buoyancy chamber above, the gas is evenly distributed at the top, which, combined with the base plate at the bottom, ensures a uniform center of gravity for the device, preventing it from being overturned by water flow during use.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are:

[0026] 1. This device uses a boat or similar vessel to drive the water flow, which impacts the propeller and provides power to the propeller. This eliminates the need for a motor and battery, and enables alternating water flow between the upper and lower parts of the device. The water pipes reciprocate to oscillate, stir, and drain the water. Combined with the fanning motion of the wing plates and the rotation of the propeller, the device moves forward stably while the water flows between the upper and lower parts of the device.

[0027] 2. This device adjusts its center of gravity by adding water to the buoyancy chamber or introducing air while water is added, combined with the drain valve below and the high-density alloy weight base plate at the bottom. It is suitable for various water densities and allows for adjustment of its position in the water, facilitating entry into water temperature stratification zones. After air is pressed into the buoyancy chamber above, the gas is evenly distributed at the top, which, combined with the base plate at the bottom, ensures a uniform center of gravity for the device and prevents it from being overturned by water flow during use.
