Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a circulating collection device suitable for small-scale water blooms of cyanobacteria. Background Technology

[0002] Algal blooms, also known as algal blooms, are ecological disasters caused by the excessive accumulation of nutrients such as nitrogen and phosphorus in water bodies, leading to a sudden and excessive proliferation of algae (such as cyanobacteria, green algae, and diatoms). They typically manifest as a green or blue-green "paint-like" layer on the water surface, and in severe cases, release toxins and consume dissolved oxygen, threatening the survival of aquatic organisms and human health. Therefore, to avoid the harm caused by algal blooms, it is usually necessary to carry out treatment such as harvesting, cleaning, and collecting algae. Chinese patent document CN219710245U discloses a cyanobacteria collection device, which includes a collection bucket, a collection pump, a treatment pool, a first collection pile, and a second collection pile. This device can collect cyanobacteria floating on the water surface in real time. After installation and debugging, it can collect cyanobacteria in real time without manual operation. Furthermore, auxiliary devices can be used to clean up garbage and floating debris from the water surface and bring them to the shore for centralized treatment. This allows for unattended, remotely controlled, and automatic operation of cyanobacteria treatment, effectively controlling algal blooms in lakes. However, this collection device is mainly suitable for flowing water bodies, i.e., rivers, which use natural wind and the rise and fall of river water to move the cyanobacteria and then collect them. For relatively static small water bodies, such as ponds, reservoirs, and small lakes, its efficiency in collecting cyanobacteria is low. In addition, the collection device requires frequent cleaning and replacement of the interception net and collection bucket to ensure interception efficiency and effectiveness, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a circulating collection device suitable for cyanobacteria blooms in small water bodies. This circulating collection device can collect and treat cyanobacteria in different small water bodies (i.e., ponds, reservoirs, small lakes, etc.), thereby avoiding ecological damage, aquatic organism mortality, and water quality problems caused by cyanobacteria blooms.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A circulating collection device for cyanobacteria blooms in small water bodies includes two main floats and two telescopic chain assemblies. The two main floats are symmetrically arranged, and their two ends are connected by the two telescopic chain assemblies. The telescopic chain assembly includes multiple small floats and multiple folded corrugated pipes. Adjacent small floats are connected to each other and to the main floats through the folded corrugated pipes. The inner walls of the two main floats and the inner walls of the multiple small floats are fixedly connected to the outer wall of the same waterproof cloth. A fixed base plate is provided in the middle layer of the waterproof cloth, which serves two purposes: first, to shape the waterproof cloth, and second, to provide counterweight for the collection device, ensuring that the waterproof cloth is recessed to form a water-accommodating cavity. Water inlet components and drainage components are respectively provided on the two main floats.

[0006] Based on further optimization of the above scheme, the water inlet assembly includes a first water inlet mechanism and a second water inlet mechanism. The first water inlet mechanism includes a first water inlet pipe, a suction pump, and a first bend. The first water inlet pipe passes through the middle of the corresponding main float and is connected to the suction pump located on the inner wall of the main float. The output end of the suction pump is provided with a first bend, and the lower end of the first bend faces the fixed base plate. The second water inlet mechanism includes a second water inlet pipe and a solenoid valve. The second water inlet pipe passes through the corresponding main float, and the solenoid valve is located on the inner wall of the main float.

[0007] Based on further optimization of the above scheme, the height of the first water inlet pipe is lower than the height of the second water inlet pipe.

[0008] Based on further optimization of the above scheme, the drainage component includes a drainage pump, a second bend pipe and an n-shaped pipe. The drainage pump is fixedly installed on the inner wall of the corresponding main float and the second bend pipe is installed at the input end of the drainage pump. The end of the second bend pipe away from the drainage pump is located on the upper side of the fixed base plate end face. The output end of the drainage pump is installed with an n-shaped pipe and the end of the n-shaped pipe away from the drainage pump is located on the outer side of the corresponding main float.

[0009] Based on further optimization of the above scheme, the end face of the main float is provided with a positioning clip corresponding to the n-shaped tube, and the n-shaped tube is clipped onto the positioning clip.

[0010] The following are the technical effects of this utility model:

[0011] This solution combines a main float with multiple smaller floats and a telescopic chain assembly consisting of multiple folded corrugated pipes, along with a waterproof fabric with a fixed base, to form a "container" that can be placed in small bodies of water to collect and contain water containing algal blooms. This "container" can adapt to different shapes of small bodies of water, effectively fitting around the edges and expanding the applicability of the collection device. Furthermore, the inclusion of inlet and outlet components not only enables effective collection of algal blooms but also facilitates the return of treated algal blooms to the water body, achieving water recycling and enhancing the overall practicality of the collection device.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1:

[0018] A circulating collection device for cyanobacteria blooms in small water bodies includes two main floats 10 and two telescopic chain assemblies, with the two main floats 10 symmetrically arranged (e.g., Figure 1 As shown, two main floats 10 are respectively located on the upper and lower sides, and their two ends are connected by two telescopic chain assemblies; the telescopic chain assembly includes multiple small floats 21 and multiple folded corrugated pipes 22 (both the main floats 10 and the small floats 21 are filled with air bladders to ensure that the entire circulation collection device floats on the water surface), and adjacent small floats 21 are connected to each other and to the main floats 10 by folded corrugated pipes 22 (e.g., Figure 1 As shown, the number of folded corrugated pipes 22 and small floats 21 is set according to the actual situation, i.e., the specific size of the water body; the inner walls of the two main floats 10 and the inner walls of the multiple small floats 21 are fixedly connected to the outer wall of the same waterproof cloth 30 (the waterproof cloth 10 is made of multiple layers of Oxford cloth, waterproof canvas, nylon coated cloth or other equivalent materials; in order to ensure the connection stability between the waterproof cloth 30 and the main floats 10 and small floats 21, and to avoid the collapse of the waterproof cloth 30, the waterproof cloth 30 is incorporated into the support plate corresponding to the main floats 10 and small floats 21, and the support plate is fixedly connected to the corresponding main floats 10 and small floats 21) and a fixed base plate 40 is set in the middle layer of the waterproof cloth 30 (such as Figure 1As shown), it is used for two purposes: firstly, to shape the waterproof cloth 30, and secondly, to counterweight the collection device to ensure that the waterproof cloth 30 is recessed to form a water-containing cavity.

[0019] The two main floats 10 are respectively equipped with water inlet components and drainage components; such as Figure 1 As shown, the water inlet assembly is mounted on the lower main float 10. The water inlet assembly includes a first water inlet mechanism and a second water inlet mechanism. The first water inlet mechanism includes a first water inlet pipe 51, a suction pump 52, and a first bend pipe 53. The first water inlet pipe 51 passes through the middle of the corresponding main float 10 and communicates with the suction pump 52 mounted on the inner wall of the main float 10. The output end of the suction pump 52 is provided with the first bend pipe 53, and the lower end of the first bend pipe 53 faces the fixed base plate 40 (e.g., ...). Figure 2 (As shown); the second water inlet mechanism includes a second water inlet pipe 54 and a solenoid valve 55 (the number of second water inlet mechanisms is not less than 2 sets, such as...). Figure 1 As shown, in this embodiment, there are two sets of second water inlet mechanisms. The second water inlet pipe 54 passes through the corresponding main float 10 and is located on the inner wall of the main float 10. A solenoid valve 55 is installed therein. (A sealing rubber ring is installed at the connection between the first water inlet pipe 51, the second water inlet pipe 54 and the main float 10 to prevent water from seeping into the inner cavity of the main float 10. The airbags of the first water inlet pipe 51, the second water inlet pipe 54 and the inner cavity of the main float 10 are positioned differently.) The height of the first water inlet pipe 51 is lower than the height of the second water inlet pipe 54 (e.g., Figure 2 (As shown).

[0020] The drainage assembly includes a drainage pump 61, a second bend 62, and an n-shaped pipe 63. The drainage pump 61 is fixedly installed on the inner wall of the corresponding main float 10, and the second bend 62 is installed at the input end of the drainage pump 61. The end of the second bend 62 away from the drainage pump 61 is located on the upper side of the end face of the fixed base plate 40 (e.g., Figure 3 (As shown); an n-shaped pipe 63 is provided at the output end of the drain pump 61, and the end of the n-shaped pipe 63 away from the drain pump 61 is located outside the corresponding main float 10 (e.g. Figure 3 (As shown). The end face of the main float 10 is provided with a positioning clip corresponding to the n-shaped tube 63, and the n-shaped tube 63 is clipped onto the positioning clip.

[0021] Working principle:

[0022] In use, the entire circulating collection device is placed on the surface of the water body to be treated. The corrugated pipes are stretched and contracted according to the edge structure of the water body to adjust the overall shape of the device, ensuring it fits snugly against the water's edge. Due to the weight of the fixed base plate 40, the first inlet pipe 51 is positioned 5-10 cm below the water surface, and the second inlet pipe 54 is positioned at the water surface. The suction pump 52 is activated to draw cyanobacteria from the water into the circulating collection device. Simultaneously, the solenoid valve is opened, allowing surface algae blooms to enter the device (the second inlet pipe 54 can be opened in real-time, continuously drawing algae blooms into the device via airflow; the solenoid valve can be closed during algae bloom treatment). Algaecides are then introduced into the device to break down the cyanobacteria and release nutrients from the algal cells. After breakdown, the treated water from the device is discharged back into the water body via the drain pump 61. Algae bloom collection is repeated, achieving circulating collection and treatment, thus completing water body restoration.

[0023] Example 2:

[0024] As another preferred embodiment of this utility model, based on the above embodiment 1, in order to prevent the collection device from being pushed away from the edge of the water body by wind and water force, thus making it difficult to treat blue-green algae, two traction ropes are set on the end face of the fixed base plate 40 and the two traction ropes pass through the corresponding waterproof cloth 30. Rope buckles are set on the end faces of the two main floats 10, and the two traction ropes pass around the corresponding rope buckles respectively. At the same time, foundation piles are set on the ground on the shore of the water body, and the collection device is positioned by connecting the two traction ropes on the foundation piles.
