Abstract
Description
Technical Field
[0001] This invention belongs to the field of lake surface cleaning technology, and in particular relates to a lake surface cleaning device and construction method. Background Technology
[0002] Southern cities typically enjoy high temperatures and abundant sunshine year-round, providing ideal natural conditions for algae growth. However, the lakes are mostly stagnant, with insufficient hydrodynamics and extremely limited self-purification capacity. Furthermore, urbanization, particularly during heavy rains, brings in nutrients like nitrogen and phosphorus from surrounding sewage and surface runoff, further exacerbating eutrophication. This combination of natural and anthropogenic factors leads to massive algal blooms and collapses, severely impacting the water's sensory indicators and ecological health. Cleaning algae typically involves spraying biological agents to flocculate them, followed by manual removal using handheld filters. This method is not only inefficient but also labor-intensive and costly. Moreover, after biological treatment, algae often form stratified flocculations on the surface, with uneven distribution and inconsistent aggregation, further complicating removal. Given the vast lake surface, manual cleaning methods are insufficient for comprehensive coverage, are intensive and time-consuming, and have limited overall effectiveness.
[0003] In existing technologies, conventional control methods mainly rely on manual spraying of biochemical agents to promote cyanobacteria flocculation, supplemented by manual removal using boats and nets for localized harvesting. This method is not only inefficient and has limited coverage, making it difficult to address large-scale algal blooms, but also suffers from high labor intensity, long-term high costs, and potential ecological impacts of the agents. Furthermore, the sparse and uneven distribution of cyanobacteria flocs and their susceptibility to wind drift further increases the difficulty of harvesting. Moreover, most vessels currently available are integrated long-arm boats, which are specialized equipment, expensive, require professional operators, have limited application scenarios, and lack flexibility, resulting in high operating costs at present. Relying solely on manual harvesting is too inefficient, requires significant personnel, and fails to achieve the desired results. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a lake surface cleaning device and construction method, which effectively solves the technical problems of high labor intensity, time and effort, low cleaning efficiency, limited coverage, high cost, and potential impact on the ecological environment caused by the use of chemicals, thus overcoming the shortcomings of existing technologies.

[0027] This invention provides a lake surface cleaning device and construction method. The embodiments of this invention will be described below with reference to the accompanying drawings.

In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.
[0029] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of the present invention provides a lake surface cleaning device, including a collection component, a towing rope 1, and a flow guiding component. The collection component can float on the lake surface. The towing rope 1 is located at both ends of the collection component and is used to pull the collection component along the lake surface to collect and gather floating objects such as blue-green algae for centralized collection. The flow guiding component is located at the bottom of the collection component, along the towing direction of the towing rope 1. In order to facilitate towing and reduce water flow resistance, the flow guiding component allows water to flow through it, playing a certain guiding role. At the same time, the flow guiding component also plays a certain counterweight role.
[0030] Specifically, the collection component includes a bottom mesh 3, with a collection section 8 at the top and a flow guiding component at the bottom. During dragging, water flows out from the bottom mesh 3, and the collection section 8 blocks floating objects such as blue-green algae from the bottom mesh 3. Preferably, the bottom mesh 3 is a rectangular wire mesh.
[0031] Specifically, the collection section 8 is configured as a pipe, which is perpendicular to the towing direction of the towing rope 1. Preferably, the collection section 8 is configured as a PVC pipe, which is lightweight and can float on the lake surface.
[0032] Specifically, the pipe fitting has a bend 6, with the open end of the bend 6 facing the front end of the towing rope 1 in the towing direction. Preferably, the pipe fitting is composed of multiple PVC pipes, which are connected by connecting elbows 7 to form the bend 6. The number of bends 6 is not limited. The bend 6 serves as a collection port, with its open end facing the front end of the towing rope 1 in the towing direction. After floating objects such as blue-green algae enter the collection port, the bend 6 blocks and collects the collected floating objects. Preferably, the pipe fitting is W-shaped.
[0033] Preferably, both ends of the pipe fitting are equipped with anti-disengagement buckles 5, which are connected to the towing rope 1. The anti-disengagement buckles 5 are fixedly connected to both ends of the pipe fitting. By setting the anti-disengagement buckles 5, the connection of the towing rope 1 is made more convenient. The anti-disengagement buckles 5 are existing technology, and their specific structure and connection method will not be described in detail here.
[0034] Preferably, the pipe fitting has plugs 2 at both ends. By setting the plugs 2, the two ends of the pipe fitting are sealed, forming an internal cavity, which is more conducive to the entire device floating on the lake surface. The plugs 2 of PVC pipes are existing technology, and the specific structure and connection method will not be described in detail here.
[0035] Specifically, the flow guiding component includes multiple flow guiding tubes 9, with the axial direction of the flow guiding tubes 9 arranged along the dragging direction of the drag rope 1. Preferably, the flow guiding tubes 9 are made of stainless steel and are evenly fixed to the bottom of the bottom mesh 3 at equal intervals.
[0036] Preferably, filter screens 10 are provided at both ends of the guide pipe 9. The filter screens 10 are fixed at both ends of the guide pipe 9 and can filter the incoming water flow to prevent impurities from entering the guide pipe 9 and clogging it, thus affecting the guiding function.
[0037] Preferably, to facilitate the connection between the collecting component and the guiding component, a buckle 4 connects the collecting part 8 and the guiding component. The buckle 4 allows for a detachable connection and fixation between the collecting part 8 and the guiding component. The buckle 4 passes through the bottom mesh 3, clamping and fixing the bottom mesh 3 between the guiding component and the collecting part 8. The specific form of the buckle is not limited. Both the collecting part 8 and the guiding component are pipe fittings, and buckles are common components for connecting pipe fittings and are existing technology. Specific structures and connection methods will not be elaborated here.
[0038] A construction method using a lake surface cleaning device as described above includes the following steps:
[0039] S1. Assemble the entire device;
[0040] Using connecting elbows 7, multiple PVC pipes are assembled into a W-shaped collection section 8. Plugs 2 are used to seal both ends of the collection section 8. Anti-disengagement clips 5 are fixed to both ends of the collection section 8, and the drag rope 1 is connected to the anti-disengagement clips 5. The bottom mesh 3 is placed at the bottom of the collection section 8, and the guide pipe 9 is evenly placed at the bottom of the bottom mesh 3. Clips 4 are used to detachably connect the guide pipe 9 to the collection section 8, clamping and fixing the bottom mesh 3 between the guide pipe 9 and the collection section 8. Filter screens 10 are fixed to both ends of the guide pipe 9.
[0041] S2. Attach the towing rope 1 to the hull so that the entire device floats on the lake surface;
[0042] S3. Start the boat. As the boat moves, it drags the collection component along the lake surface. Floating debris such as blue-green algae, which is difficult to collect, will enter the collection component with the water flow. The water is discharged through the bottom mesh 3, and the collection part 8 blocks and collects the floating debris, such as blue-green algae, in the accumulation port, i.e., the bending part 6. During the dragging process, water flows through the guide component, which plays a certain role in guiding the flow and counterweighting.
[0043] S4. Manually collect the floating matter such as blue-green algae accumulated in the collection unit into garbage bags.
[0044] Example: A lake surface cleaning device includes a collection component, a towing rope 1, and a flow guiding component. The collection component includes a bottom mesh 3, with a collection section 8 at the top and a flow guiding component at the bottom. The bottom mesh 3 is a rectangular 120-mesh steel wire mesh. The collection section 8 is a pipe, perpendicular to the towing direction of the towing rope 1. The pipe is formed by connecting multiple PVC pipes with elbows 7, forming a W shape, with the open end of the W facing the front end of the towing rope 1 in the towing direction. Anti-disengagement buckles 5 are fixed at both ends of the pipe, and the anti-disengagement buckles 5 are connected to the towing rope 1. The two ends of the pipe are sealed with plugs 2. The flow guiding component includes multiple flow guiding pipes 9, with the axial direction of the flow guiding pipes 9 along the towing direction of the towing rope 1. The flow guiding pipes 9 are made of stainless steel and are evenly fixed at the bottom of the bottom mesh 3. Filter screens 10, made of dense fiber mesh, are fixed at both ends of the flow guiding pipes 9. A snap-fit connection 4 is used between the guide pipe 9 and the PVC pipe fitting for detachable connection, and the bottom mesh 3 is clamped and fixed between the guide pipe 9 and the PVC pipe fitting.
[0045] The advantages and positive effects of this invention are:
[0046] 1. By towing the vessel, continuous and large-scale automatic collection of floating debris such as blue-green algae is achieved, ensuring the cleaning effect, reducing reliance on manpower, reducing labor intensity, improving cleaning efficiency, reducing cleaning costs and safety hazards, and preventing secondary pollution to the environment.
[0047] 2. With its simple structure and convenient operation, it can clean not only the vast deep water areas of the lake, but also the narrow shallow water areas, making it suitable for operations in different open waters and achieving the purpose of all-round cleaning.
