Description

Technical Field

[0001] This utility model belongs to the field of water conservancy technology, and in particular relates to a drainage device for water conservancy projects. Background Technology

[0002] Drainage requires a water pump as a power source. The water pump submerges the inlet end of the connected inlet pipe into the water. The water conditions are complex. As the water pump operates, impurities in the water will enter the inlet pipe due to the pump's suction, causing blockage and damage to the pump. Alternatively, a filter screen can be installed at the inlet end of the inlet pipe, but impurities will be adsorbed onto the filter screen due to the suction of the pump, thus affecting the inlet efficiency of the inlet pipe. Therefore, we designed a drainage device for hydraulic engineering, which adds an automatically cleaning filter structure to the end of the inlet pipe to improve drainage efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a drainage device for water conservancy projects, which has the advantage of adding an automatically cleanable filter structure to the end of the inlet pipe to improve drainage efficiency, thereby solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drainage device for water conservancy projects includes a water pump assembly: the water inlet of the water pump assembly is connected to a water inlet pipe, a frustum-shaped pipe connected to the water inlet pipe is installed at the end of the water inlet pipe away from the water pump assembly, a connecting plate is fixedly connected to the bottom of the frustum-shaped pipe, a plurality of outer steel columns are fixedly connected to the bottom of the connecting plate in a circular array, a base plate is fixedly connected to the bottom of the plurality of outer steel columns, a rotatable rotating cylinder is provided above the base plate, a plurality of filter holes are opened on the surface of the rotating cylinder, two symmetrical scrapers are fixedly connected to the top of the outer steel columns, the inner side of the scrapers is attached to the surface of the rotating cylinder, and a fan blade extending into the inner cavity of the frustum-shaped pipe is fixedly installed in the inner cavity of the rotating cylinder.

[0005] Preferably, a connecting column is fixedly connected to the bottom of the fan blade, and side connecting rods are fixedly connected to both sides of the surface of the connecting column. The end of the side connecting rod away from the connecting column is welded to the inner wall of the rotating drum.

[0006] Preferably, a frustum block is fixedly connected to the surface of the connecting column, and the frustum block is fixedly connected to the bottom of the fan blade.

[0007] Preferably, a bearing seat is fixedly connected to the top of the outer retaining steel column, a rotating rod is fixedly connected to the inner ring of the bearing seat, and the top of the rotating rod is fixedly connected to the rotating cylinder.

[0008] Preferably, a limiting groove is formed on the top of the connecting plate, and the top of the surface of the rotating drum is in contact with the inner wall of the limiting groove.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model submerges the structure below the frustum-shaped tube in water. During the operation of the water pump assembly, water enters the frustum-shaped tube through the filter holes. The water flow drives the fan blades to rotate, and the fan blades drive the rotating drum to rotate. Larger debris in the water is blocked by multiple outer steel columns, while smaller debris entering the filter holes is scraped off by the scraper due to the rotation of the drum. This effectively prevents the filter holes on the surface of the drum from being blocked, thus achieving the purpose of adding an automatically cleaning filter structure to the end of the water inlet pipe to improve drainage efficiency.

[0011] 2. By setting up the frustum block, the water flow moves from bottom to top, and the water flow impacting the surface of the frustum block will spread out, so that the water is evenly distributed on the blades of the fan, thereby making the fan blades rotate more smoothly.

[0012] 3. By setting the limiting groove, this utility model can guide and limit the rotation of the top of the rotating drum surface, thus ensuring the stability of the rotation of the top of the rotating drum surface. Attached Figure Description

[0019] In the following description, embodiments of the drainage device for water conservancy projects according to the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-3This invention illustrates a drainage device for water conservancy projects according to an embodiment of the present invention. It includes a water pump assembly 1. The water pump assembly 1 has an inlet pipe 2 connected to its inlet. A frustum-shaped pipe 3 connected to the inlet pipe 2 is installed at the end of the inlet pipe 2 away from the water pump assembly 1. A connecting plate 4 is fixedly connected to the bottom of the frustum-shaped pipe 3. Multiple outer steel columns 5 are fixedly connected in a circular array to the bottom of the connecting plate 4. A base plate 6 is fixedly connected to the bottom of the multiple outer steel columns 5. A rotatable rotating cylinder 7 is arranged above the base plate 6. A bearing seat 14 is fixedly connected to the top of the outer steel columns 5. A rotating rod 15 is fixedly connected to the inner ring of the bearing seat 14. The top of the rotating rod 15 is fixedly connected to the rotating cylinder 7. Multiple filter holes 8 are formed on the surface of the rotating cylinder 7. A limiting groove 16 is formed on the top of the connecting plate 4. The top surface of the rotating cylinder 7 is in contact with the inner wall of the limiting groove 16. Through the setting of the limiting groove 16, the filter holes 8 can be filtered. The rotation of the top surface of the rotating drum 7 is guided and limited, ensuring the stability of the rotation of the top surface of the rotating drum 7. Two symmetrical scrapers 9 are fixedly connected to the top of the outer steel column 5. The inner side of the scraper 9 is attached to the surface of the rotating drum 7. The inner cavity of the rotating drum 7 is fixedly installed with a fan blade 10 extending into the inner cavity of the frustum tube 3. The bottom of the fan blade 10 is fixedly connected with a connecting column 11. Side connecting rods 12 are fixedly connected to both sides of the surface of the connecting column 11. The end of the side connecting rod 12 away from the connecting column 11 is welded to the inner wall of the rotating drum 7. A frustum block 13 is fixedly connected to the surface of the connecting column 11. The frustum block 13 is fixedly connected to the bottom of the fan blade 10. Through the setting of the frustum block 13, the water flow moves from bottom to top. The water flow impacting the surface of the frustum block 13 will spread out, so that the water is evenly distributed on the blades of the fan blade 10, thereby making the fan blade 10 rotate more smoothly.

[0021] Working principle: When using this utility model, the user submerges the structure below the frustum tube 3 in water. During the operation of the water pump assembly 1, water enters the rotating drum 7 through the filter hole 8. Then, the water flow impacts the frustum block 13 and is dispersed onto the fan blade 10. The water flow drives the fan blade 10 to rotate. The fan blade 10 drives the rotating drum 7 to rotate through the connecting column 11 and the side connecting rod 12. Larger debris in the water is blocked by multiple outer steel columns 5. Small debris that enters the filter hole 8 is scraped off by the scraper 9 due to the rotation of the rotating drum 7, effectively preventing the filter hole 8 on the surface of the rotating drum 7 from being blocked and affecting the water intake efficiency.

[0022] In summary, this drainage device for water conservancy projects, by submerging the structure below the frustum-shaped pipe 3 in water, allows water to enter the frustum-shaped pipe 3 through the filter holes 8 during the operation of the pump assembly 1. The water flow drives the fan blades 10 to rotate, which in turn drives the rotating drum 7 to rotate. Larger debris in the water is blocked by multiple outer steel columns 5, while smaller debris entering the filter holes 8 is scraped off by the scraper 9 due to the rotation of the rotating drum 7. This effectively prevents the filter holes 8 on the surface of the rotating drum 7 from being blocked, thus achieving the purpose of adding an automatically cleaning filter structure to the end of the water inlet pipe and improving drainage efficiency.
