Description

Technical Field

[0001] This utility model relates to the field of algal bloom control technology, and in particular to a device for extracting surface water using the siphon principle. Background Technology

[0002] Reservoirs, especially river-type reservoirs, are prone to algal blooms in front of dams, affecting water quality safety and the compliance of surface water monitoring sections. During an algal bloom, more than 70%-90% of the blue-green algae accumulate in the top 0-20cm of the water. Reservoir dams primarily discharge water from the bottom layer, so simply releasing water through dams is unlikely to control algal blooms.

[0003] Therefore, there is an urgent need to research a device that can extract and separate surface water to control algal blooms and ensure water quality safety. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The purpose of this invention is to provide a device for extracting surface water using the siphon principle, in order to solve the problems existing in the prior art.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1:

[0029] This embodiment provides a device for extracting surface water using the siphon principle, such as... Figure 1 As shown, it includes:

[0030] Water intake head 1 is a square trumpet-shaped structure. As a water intake component, it is mainly used to collect water containing algal blooms.

[0031] Hose 12, which is connected to water intake head 1, is used to transport water and can be a rubber hose or a corrugated pipe.

[0032] The float 8 is connected to the side of the water intake head 1 and the side of the hose 12, and is used to provide buoyancy for the water intake head 1 and the hose 12 so that they can be suspended at a suitable water level.

[0033] As one implementation method, such as Figure 2 As shown, the water intake head 1 includes a side plate 16, which can be made of sheet metal. The side plate 16 is welded together to form a square horn-shaped structure. The small end 4 of the square horn-shaped structure is welded and fixed to a base plate 5, which can be made of sheet metal. A connecting cylinder 6 is welded and fixed to the outside of the base plate 5 for connecting the hose 12, which can be made of iron. A through hole is cut in the middle of the base plate 5, and the through hole communicates with the connecting cylinder 6, thereby realizing the connection between the hose 12 and the water intake head 1.

[0034] As one implementation method, both the large end 14 and the small end 4 of the square horn-shaped structure are provided with shaping edging 2, which can be welded to the square horn-shaped structure with angle iron to achieve the shaping effect. After shaping, the large end 14 is a square structure with a side length of 0.5m, and the small end 4 is a square structure with a side length of 0.25m. Of course, in actual applications, the opening size of the water intake head 1 can be adjusted according to the water intake volume requirements to improve the water intake efficiency.

[0035] As one implementation, a supporting rib 3 is welded at the connection between the side plates 16. The rib can be made of steel bars and serves as a support.

[0036] As one implementation method, such as Figure 3 As shown, the side wall of the connecting cylinder 6 and the side wall of the end of the hose 12 are provided with matching connecting holes 7, which can be through holes with a diameter of 10mm. Connecting bolts are inserted into the connecting holes 7 to achieve a fixed connection between the two.

[0037] In one embodiment, the end of the hose 12 is provided with a flange ball valve 13, which is a DN250 model and is used to control drainage.

[0038] As one implementation method, an exhaust valve is provided in the middle of the hose 12, which is located at the highest position during installation to prevent air blockage from affecting the siphon and also to break the vacuum.

[0039] As one implementation method, both the side of the water intake head 1 and the side of the hose 12 are provided with connecting ears. The connecting ears are connected to the floats 8 through the connecting rope 9. The number of floats 8 can be determined according to actual needs. The more floats, the greater the buoyancy. At the same time, the position of the water intake head 1 can be controlled by adjusting the length of the connecting rope 9 to achieve the collection of water at different depths from the surface, such as collecting water layers of 0-5cm, 0-10cm, etc.

[0040] This utility model provides a device for extracting surface water using the siphon principle. Its usage and working principle are as follows: Figure 4 As shown, the water intake head 1 is made of square trumpet-shaped structure using materials such as sheet metal, steel bars, and angle steel. The small end 4 is welded to the base plate 5, and the base plate 5 is welded to the connecting cylinder 6. The opening size of the base plate 5 is the same as the diameter of the connecting cylinder 6, and the diameter of the connecting cylinder 6 is directly matched with the hose 12. After being connected by a socket, it is fixed with bolts. The connected hose 12 and the water intake head 1 are tied to the float 8 by the connecting rope 9. The length of the connecting rope 9 is controlled so that it floats on the water surface under the action of gravity and buoyancy. The hose 12 is fixed to the top of the dam 15 by U-shaped pipe clamps 10 and expansion bolts 11. A DN250 flange ball valve 13 is installed at the hose 12 at the bottom of the dam 15 to facilitate the control of water drainage. When the water in the dam is discharged to a certain height, the drainage ball valve is closed or the air vent valve is opened manually, and the siphon is interrupted.

[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
