Description

Technical Field

[0001] The invention relates to an algae control and ecological floating island nutrition supply device based on copper rust ring edge snails, and belongs to the technical field of biological algae control. Background Art

[0002] Under the dual influence of global climate change and human activities, the eutrophication problem of lakes and reservoirs is becoming increasingly serious, resulting in frequent occurrence of cyanobacterial blooms, which has become a global water environment problem. In particular, Pseudo-cylindrical spores, a cyanobacteria with strong adaptability and the ability to produce toxins, have gradually become the dominant species in some eutrophic water bodies in my country, exacerbating the threat of algal blooms to human health. Since Pseudo-cylindrical spores are tiny and evenly distributed in the water, traditional physical algae removal technologies, such as filtration, flotation, pressurization, and ultrasound, are not ideal for its treatment. In order to improve the removal efficiency, it is usually necessary to combine flocculation pretreatment to increase the particle size of the algae particles, thereby improving the filtration effect.

[0003] Existing flocculation and filtration technologies have some limitations in the management of algal blooms in water sources. First, due to the use of chemical agents, these technologies may not be suitable for environmentally sensitive water sources. Secondly, although commonly used flocculants such as polyaluminium chloride can effectively flocculate, the flocs formed are often loose and fragile, which limits their potential in improving filtration efficiency. Furthermore, these agents are usually used once. In order to maintain a continuous flocculation effect, they need to be continuously replenished, which not only increases costs, but also involves continuous manpower and energy consumption for the supply and treatment of agents.

[0004] For this purpose, an algae control and ecological floating island nutrient supply device based on the copper rust ring-edge snail was designed to optimize the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide an algae control and ecological floating island nutrition supply device based on copper rust ring edge snails. The algae-containing water is introduced into the interior of the cylinder, and the copper rust ring edge snails raised between the metal grilles are used to feed and enrich the algae. Then the excrement of the snails is concentrated and transported to the ecological floating island to provide nutrition for the plants on the ecological floating island. This process not only achieves the removal of algae, but also promotes the recycling of resources. This method is safe and environmentally friendly and helps to maintain the balance of the water ecosystem. In addition, no chemical reagents are used throughout the process. A combination of biological and mechanical filtration is adopted, which is safe and harmless, and can sustainably control the algae bloom problem in the water source. The annular floating plate, rectangular collecting bucket, water pump, and corrugated telescopic pipe are used. The algae water adding mechanism composed of a discharge cover, a gear ring, a motor, a gear, a liquid level switch, a vertical groove, a limit block, an annular slide groove and a slider can control the rectangular collecting bucket to rotate circumferentially on the outside of the cylinder to salvage the algae during use, thereby increasing the algae oil content in the algae water and automatically adding the water source containing the algae to the inside of the cylinder, which is more convenient to use. The cleaning structure composed of an impeller installed through the internal rotation of the algae discharge pipe and a shaft, a second brush plate and a scraper can use the impact force of the water flow to control the rotation of the impeller during the discharge of excrement, thereby driving the second brush plate and the scraper to rotate, ensuring the smooth flow of the metal grille and ensuring that the excrement inside the cylinder is completely discharged, which is more practical.

[0039] The overall working principle is as follows: when in use, the copper-rust ring-edge snails are raised between two groups of metal grilles 6, the device is self-powered by the power supply mechanism 8, the algae-containing water source is injected into the interior of the cylinder 1 by the algae water adding mechanism 7, the copper-rust ring-edge snails are used to ingest and enrich the algae, and the snail excrement falls to the bottom of the cylinder 1, and the timing switch controller 10 is used to control the timing start of the lifting pump 4, and the snail excrement is extracted and concentrated and transported to the interior of the supply mechanism 5, and then the supply mechanism 5 sprays the excrement from the top into the planting trough of the plant to provide nutrition for the plants of the ecological floating island 2. In addition, in the process of discharging the excrement, the cleaning mechanism 9 is used to clean the metal grille 6 and the bottom of the cylinder 1 to ensure the smooth falling and collection of the excrement. When the excrement extraction is completed, the algae water is added again by the algae water adding mechanism 7, and the above steps are repeated to continuously control the algae and supply nutrients to the ecological floating island 2.

[0040] In this embodiment, the supply mechanism 5 includes an annular pipe 501, a support rod 502 and a straight pipe 503. The annular pipe 501 is evenly fixed on the top of the ecological floating island 2. Multiple groups of annular pipes 501 are nested with each other, and discharge ports are opened at the bottom of the annular pipes 501.

A support rod 502 is fixed between the bottom of the annular pipe 501 and the ecological floating island 2, and the output end of the lifting pump 4 is connected to the annular pipe 501.

[0041] Partial working principle: the excrement and water source extracted by the lifting pump 4 enter the annular pipe 501, and then the excrement is evenly sprayed out through the discharge port at the bottom of the annular pipe 501 to supplement the nutrition of the plants.

[0042] In this embodiment, the cleaning mechanism 9 includes a shaft 901, an impeller 902, a second brush plate 903 and a scraper 904. The shaft 901 is vertically rotatably installed at the top of the discharge pipe 3. The impeller 902 is installed at the bottom end of the shaft 901 and located inside the discharge pipe 3. The top of the shaft 901 passes through the metal grille 6. The top of the shaft 901 is installed with a second brush plate 903 that fits with the metal grille 6. The side of the shaft 901 is fixed with a scraper 904 that fits with the bottom end of the cylinder 1.

[0043] Local working principle: When the excrement and water source are extracted, the flow rate of the water source will increase after entering the discharge pipe 3, which will exert thrust on the impeller 902 to control the rotation of the shaft 901. The shaft 901 drives the second brush plate 903 and the scraper 904 to rotate, cleaning the metal grille 6 and the bottom of the cylinder 1 respectively.

[0044] In this embodiment, the algae water adding mechanism 7 includes an annular float 701, a rectangular collecting bucket 702, a water pump 703, a bellows 704, a discharge cover 705 and a rotating assembly 706. The annular float 701 is sleeved on the outside of the cylinder 1 and floats on the liquid surface. A rectangular collecting bucket 702 is vertically fixed on the cross-section of the outer side of the annular float 701. A water pump 703 is installed inside the annular float 701. The input end of the water pump 703 is connected to the inside of the rectangular collecting bucket 702. The output end of the water pump 703 is installed with a bellows 704.

[0045] Local working principle: When adding algae water, the rotating component 706 is used to control the rotation of the annular float 701, and the annular float 701 drives the rectangular collecting bucket 702 to rotate around the outside of the cylinder 1 to collect the algae around the cylinder 1, and start the water pump 703 to extract the water source and algae, and then spray them out from the discharge cover 705 through the corrugated telescopic tube 704 and discharge them into the interior of the cylinder 1.

[0046] In this embodiment, the rotating component 706 includes a gear ring 7061, a motor 7062, a gear 7063 and a liquid level switch 7064.

When algae water is added, the motor 7062 and the water pump 703 are controlled by the liquid level switch 7064.

[0048] In this embodiment, vertical grooves 7065 are uniformly and vertically opened on the outer side of the cylinder 1 , and limit blocks 7066 are slidably installed inside the vertical grooves 7065 , and the limit blocks 7066 are fixedly connected to the inner wall of the gear ring 7061 .

[0049] Partial working principle: When the gear ring 7061 moves up and down along with the annular floating plate 701, the limit block 7066 slides inside the vertical groove 7065, ensuring that the gear ring 7061 does not rotate.

[0050] In this embodiment, an annular slide groove 7067 is provided on the top of the annular floating plate 701 , and a slider 7068 is evenly slidably provided inside the annular slide groove 7067 , and the top of the slider 7068 is fixedly connected to the gear ring 7061 .

The solar panel 802 is evenly mounted on the bottom of the outer side of the mounting tube 801 along the circumferential direction. The battery pack 803 is mounted on the outer side of the mounting tube 801.

[0053] Partial working principle: During use, electricity is generated through solar energy and stored in the battery pack 803 to self-power the device.

[0054] In this embodiment, the discharge hood 705 is installed on the mounting tube 801, and a limiting ring 804 is horizontally fixed at the bottom end of the outer side of the mounting tube 801. Sliding holes 805 are evenly opened on the limiting ring 804. Vertical rods 806 are slidably installed inside the sliding holes 805, and the bottom ends of the vertical rods 806 are fixedly connected to the annular floating plate 701.

[0055] Partial working principle: During the rotation of the annular floating plate 701, the vertical rod 806 can apply thrust to the limit ring 804, thereby controlling the installation tube 801 to rotate on the top of the cylinder 1, and the algae water is discharged in a circumferential rotation.
