Description

Technical Field

[0001] The utility model belongs to the technical field of water ecological restoration, and in particular relates to an underwater collection blanket for floating plant debris used for river and lake water ecological restoration. Background Art

[0002] With the continuous enhancement of ecological and environmental awareness, river and lake water ecological restoration technology has received increasing attention. As an important means of ecological restoration, floating plants are widely used in water quality improvement and environmental beautification projects. Floating plants such as water lilies, water hyacinths, water duckweed, water turtles, etc., whose stems and leaves can float in the water or stand upright on the water surface, have a significant effect on fixing N and P in the water body, which is extremely beneficial for water quality restoration.

[0003] However, in actual application, floating plants will also encounter some problems. Similar to other aquatic plants, floating plants will inevitably drop some plant residues in the water. These residues are usually produced during the natural growth, metabolism and decomposition of plants. If these plant residues are not handled in time, they will have an adverse effect on the aquatic ecosystem, such as causing turbidity in the water. After dissolving in the water, it may cause eutrophication of the water, thereby affecting the effect of plant restoration and even deteriorating the water quality.

[0004] In addition, the debris layer formed by the accumulation of floating plant debris at the bottom of the water is easily affected by the impact of the water flow and scattered to other parts of the water body, which will not only affect the water quality of other waters, but also expand the scope of pollution. More seriously, when these debris are deposited on the surface of the bottom mud, a peat layer rich in organic matter will be formed over time. These peat layers will continue to release substances such as T and P into the water body, forming secondary endogenous pollution, thereby reducing the effect of ecological restoration and further affecting water quality.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] See also Figures 1 to 6 , an underwater collection blanket for floating plant debris for river and lake water ecological restoration, including a flexible salvage net 61, used to salvage floating debris in the water. The flexible salvage net can effectively salvage and collect floating debris in the water. Its flexible characteristics can better adapt to the fluctuations of the water body and improve the collection efficiency of the debris. The preferred material of the flexible salvage net is nylon nylon net with a mesh number of 60 to 80 meshes. The purpose of this setting is that when the plant debris in the water body falls on the flexible salvage net 61, it is collected by the flexible salvage net, and the flexible salvage net is transferred to the shore for centralized treatment to reduce the impact on the water quality of the water body; the shape of the flexible salvage net is preferably a rectangular structure, which can be planned and cut according to the area of ​​the debris collection area.

[0027] The flexible salvage net is connected to a first float 63 on all sides, and the float is an inflatable float. When the first float is inflated, when the buoyancy of the first float is greater than the overall weight, the first float drives the flexible salvage net to float in the water and float to the water surface. This design makes it easy to lift the collection blanket to the water surface when needed, which is convenient for cleaning and transferring debris. A vent pipe 12 is provided on the first float, and the vent pipe is preferably a flexible pipe. A second float is provided at the upper end of the vent pipe, and the second float is preferably a foam float 11, which is connected to the vent pipe by means of a harness binding, or fixed above the vent pipe by means of a sleeve connection. The second float ensures that the upper end of the vent pipe is always above the water surface, and the end of the vent pipe An air nozzle 13 for inflation or exhaust is installed. This design facilitates the inflation or exhaust operation of the first float 63 by an air pump, thereby controlling the buoyancy or sinking of the collecting blanket; the second float ensures that the upper end of the vent pipe is always above the water surface to prevent water from entering the vent pipe and affecting the inflation or exhaust effect; counterweight blocks 620 and / or anchor blocks 621 connected to the first float are evenly arranged around the flexible salvage net. These counterweight blocks or anchor blocks provide the collecting blanket with necessary counterweights, ensuring that the collecting blanket can stay stably at the bottom of the water body, providing the collecting blanket with necessary stability and fixing force, ensuring that the collecting blanket can stay stably at the designated position of the water body, and improving the debris collection efficiency.

[0028] Preferably, the flexible salvage net is provided with mounting holes 73 around it, and adjacent mounting holes are spaced a certain distance apart. The mounting holes are continuously penetrated with salvage net connecting ropes 72, and the salvage net connecting ropes are flexibly connected to the first floating body at multiple points. The design of the mounting holes facilitates the insertion of the salvage net connecting ropes, and the multiple-point flexible connection between the ropes and the first floating body ensures a stable connection between the salvage net and the floating body, while allowing a certain degree of flexibility to adapt to the fluctuations of the water body.

[0029] Preferably, upwardly tilted baffles 610 are provided around the flexible salvage net, and these baffles can further prevent debris from overflowing from the edge of the salvage net.

[0030] Preferably, see Figure 7 A third buoy 612 is provided around the enclosure to keep the enclosure upright in the water, thereby ensuring that the enclosure always remains upright in the water, thereby improving the efficiency of debris collection.

[0031] Preferably, see Figure 8 The enclosure is provided with storage ropes 613 around it, which facilitate the rapid folding or deployment of the collection blanket when needed, and facilitate salvage and dragging. After the storage ropes 613 are dragged, the flexible salvage net will form a net bag structure with a narrowed upper end to prevent the collected debris from falling or escaping the flexible salvage net due to water flow.

[0032] Preferably, the counterweight block or anchor block is connected to a counterweight cable 71, and the counterweight cable is connected to the first buoy.

[0033] Preferably, the first float includes several air bags 630 connected in series, and adjacent air bags are connected by a conduit 64 to form a float after being inflated. The conduit is preferably made of butyl rubber, which is soft and can expand to form a support after being inflated. This design enables the first float to form a stable float structure after being inflated, and the conduit also provides a convenient inflation path.

[0034] Preferably, the first float can also be a continuous and through air bag, which forms a float after being inflated. Both sides of the air bag are provided with connecting ears for connecting counterweight cables and salvage net connecting cables, and the connecting ears are provided with through holes for passing the cables.

[0035] Preferably, the catheter is provided with a fixing ring 65 for connecting the counterweight cable and the salvage net connecting cable, and the outer diameter of the fixing ring is larger than the outer diameter of the catheter. The purpose of this arrangement is to allow the connecting catheter 64 to pass through the hole on the fixing ring 65, while facilitating the connection of the counterweight cable and the salvage net connecting cable, thereby enhancing the overall stability and ease of use.

[0036] Operation method of underwater debris collection blanket for floating plants in river and lake water ecological restoration

[0037] 1. Installation and deployment

[0038] 1.1. Plan and cut the flexible salvage net of appropriate size according to the area where debris needs to be collected.

[0039] 1.2. Pass the salvage net connecting ropes through the installation holes around the flexible salvage net to ensure that the ropes and cables are flexibly connected to the first buoy at multiple points.

[0040] 1.3. Check the first float to ensure it is intact and has no air leaks.

[0041] 1.4. Connect the first buoy to the counterweight cable and the salvage net connecting cable through the connecting ears and through holes to ensure a firm connection.

[0042] 1.5. If a first float consisting of multiple air bags is used, check whether the conduit is unobstructed and install a fixing ring on the conduit for connecting the rope.

[0043] 1.6. Connect the counterweight block or anchor block to the first buoy through the counterweight rope to provide the necessary stability and fixing force.

[0044] 1.7. If there is a fence, ensure that the third buoy around the fence is inflated and intact so that the fence remains upright in the water.

[0045] 1.8. Move the floating plants in the water area to other water areas, put the collecting blanket into the water, and adjust the balance between the counterweight and the float to make the collecting blanket stay stably at the designated position of the water body, such as sinking to the bottom or suspending in the water body.

[0046] 2. Use and Operation

[0047] 2.1. Check the status of the collection blanket regularly to ensure its position and stability in the water.

[0048] 2.2. When plant debris falls on the flexible salvage net, the flexible salvage net will effectively collect and intercept the debris.

[0049] 2.3. When it is necessary to clean and transfer the debris, the first float is inflated through the air nozzle on the vent pipe to raise the collection blanket to the water surface.

[0050] 2.4. Use the collection rope to drag the collection blanket to the shore for centralized processing. During the dragging process, the flexible salvage net forms a net bag, that is, a shape with a low middle and high surroundings. The benefit of this arrangement is that the collected debris will not fall off during the dragging process of the flexible salvage net 61.

[0051] 2.5. After cleaning the debris, the first float can be vented to allow the collection blanket to sink back to the designated position in the water to continue collecting debris.
