Description

Technical Field

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

[0002] Flood prevention and control, and the full development and utilization of water resources have become major issues in contemporary socio-economic development. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production.

[0003] Traditional pumping devices typically involve placing a water pipe into a reservoir or river and then securing the inlet end of the pipe with a heavy object. However, this method can draw silt from the bottom of the water into the pipe, and placing it on the surface can attract floating debris, affecting the operation of the pump. Therefore, a new pumping device for water conservancy projects is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water pumping device for water conservancy projects, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a water pumping device for a water conservancy project, including a circular mounting frame. The four sides of the circular mounting frame are bent downwards. Multiple mounting grooves are formed on the outer circular surface of the circular mounting frame. A first filter screen is provided inside each of the multiple mounting grooves. A circular float is fixedly connected to the bottom surface of the circular mounting frame. A rotary joint is provided in the middle of the circular mounting frame. A pump set is provided on one side of the circular mounting frame and is connected to the rotary joint through a pipe. A second filter screen is provided on the bottom surface of the circular mounting frame. The bottom of the second filter screen protrudes downwards, and a first counterweight is provided at the bottom end inside the second filter screen.

[0006] Preferably, in any of the above embodiments, a first clamping ring is provided at the edge of the top surface of the circular mounting bracket. The bottom surface of the first clamping ring is in contact with the top surface of the plurality of first filter screens. In this embodiment, the inner ring of the first clamping ring is fixedly connected to the top surface of the circular mounting bracket by screws, thereby facilitating the positioning of the plurality of first filter screens. The plurality of first filter screens can be made of perforated mesh plates, which are then punched and bent to facilitate installation inside the plurality of mounting slots, thus facilitating initial installation and subsequent disassembly and replacement.

[0007] Preferably, in any of the above embodiments, a second clamping ring is provided on the bottom surface at the edge of the circular mounting bracket. The second clamping ring clamps the top of the second filter screen. In this embodiment, the middle part of the second clamping ring is fixedly connected to the bottom surface at the edge of the circular mounting bracket by bolts, thereby facilitating the clamping of the top of the second filter screen.

[0008] Preferably, in any of the above embodiments, U-shaped rings are fixedly connected to all four sides of the top surface of the circular mounting frame, and a connecting rope is fixedly connected to the outer wall of one of the U-shaped rings, with its bottom end extending into the water. A second counterweight is fixedly connected to the bottom end of the connecting rope. In this embodiment, the connecting rope facilitates the fixed connection of the second counterweight to the U-shaped ring. When the second counterweight is placed in the water, it sinks to the bottom, making it easy to pull the circular mounting frame and preventing the circular mounting frame from moving with the waves or water flow.

[0009] Preferably, the bottom end of the first counterweight is threaded with a fixing bolt, which presses the bottom end of the second filter screen against the first counterweight. This method facilitates the fixed connection between the bottom end of the first counterweight and the second filter screen, thereby preventing relative sliding between the first counterweight and the second filter screen.

[0010] This utility model has the following advantages: 1. The water pumping device for this water conservancy project, by setting up a circular mounting frame with a circular float on its bottom surface, facilitates the overall deployment into the water. The circular float allows the entire device to float on the water surface. By setting up multiple first and second filter screens, which together with the circular mounting frame form a filtration barrier, foreign objects are blocked. When the pump unit is powered on, water is pumped out from inside the circular mounting frame, effectively preventing foreign objects from entering the pump unit, thereby effectively solving the problems existing in the prior art.

[0011] 2. The pumping device of this water conservancy project is equipped with a U-shaped ring, a connecting rope and a second counterweight. When in use, the second counterweight is put into the water and sinks to the bottom, which facilitates the pulling and limiting of the device. By setting the first counterweight, the second filter screen is deployed by its own weight, which prevents it from being blocked by the water flow. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0015] like Figures 1 to 5 As shown, a water pumping device for a water conservancy project includes a circular mounting frame 1. The four sides of the circular mounting frame 1 are bent downwards. Multiple mounting grooves 14 are opened on the outer circular surface of the circular mounting frame 1. A first filter screen 5 is installed inside each of the multiple mounting grooves 14. A circular float 11 is fixedly connected to the bottom surface of the circular mounting frame 1. A rotary joint 2 is provided in the middle of the circular mounting frame 1. A pump group 4 is provided on one side of the circular mounting frame 1 and is connected to the rotary joint 2 through a pipe. A second filter screen 6 is provided on the bottom surface of the circular mounting frame 1. The bottom of the second filter screen 6 protrudes downwards. A first counterweight block 12 is provided at the bottom inside the second filter screen 6.

[0016] A first clamping ring 10 is provided at the edge of the top surface of the circular mounting bracket 1. The bottom surface of the first clamping ring 10 is in contact with the top surface of the multiple first filter screens 5. As an optional technical solution of this utility model, the inner ring of the first clamping ring 10 is fixedly connected to the top surface of the circular mounting bracket 1 by screws, which facilitates the limiting of the multiple first filter screens 5. The multiple first filter screens 5 can be made of perforated mesh plates, which are then punched and bent to facilitate installation inside the multiple mounting slots 14, facilitating the initial installation and subsequent disassembly and replacement.

[0017] A second clamping ring 9 is provided on the bottom surface of the edge of the circular mounting bracket 1. The second clamping ring 9 clamps the top of the second filter screen 6. As an optional technical solution of this utility model, the middle part of the second clamping ring 9 is fixedly connected to the bottom surface of the edge of the circular mounting bracket 1 by bolts, so as to facilitate clamping the top of the second filter screen 6.

[0018] U-shaped rings 3 are fixedly connected to all four sides of the top surface of the circular mounting frame 1. A connecting rope 8 is fixedly connected to the outer wall of one U-shaped ring 3, and its bottom end extends into the water. A second counterweight 7 is fixedly connected to the bottom end of the connecting rope 8. As an optional technical solution of this utility model, the connecting rope 8 facilitates the fixed connection between the second counterweight 7 and the U-shaped ring 3. When the second counterweight 7 is placed in the water, it sinks to the bottom, which facilitates the pulling of the circular mounting frame 1 and prevents the circular mounting frame 1 from moving with the waves or water flow.

[0019] The bottom end of the first counterweight 12 is threaded with a fixing bolt 13, which presses the bottom end of the second filter screen 6 against the first counterweight 12. As an optional technical solution of this utility model, this makes it easy to fix the bottom end of the first counterweight 12 and the second filter screen 6, thereby avoiding relative sliding between the first counterweight 12 and the second filter screen 6.

[0020] The following steps are required when using the pumping device of this water conservancy project: 1) When in use, the whole thing is placed in the water, and the round float 11 makes it easy for the whole thing to float on the water surface; 2) After adjusting the placement of the device, the second counterweight 7 is placed in the water to limit the overall position of the device; 3) Pump set 4 is powered on and operates to extract water from inside the circular mounting frame 1 through the pipeline; 4) Multiple first filter screens 5 and second filter screens 6 form a filtration barrier to filter impurities.

[0021] In summary, when the user uses the device, a circular mounting frame 1 with a circular float 11 on its bottom surface is installed, making it easy to place the entire device into the water. The circular float 11 allows the device to float on the water surface. Multiple first filter screens 5 and second filter screens 6 are installed, forming a filtration barrier with the circular mounting frame 1 to block foreign objects. When the pump unit 4 is powered on, water inside the circular mounting frame 1 is extracted, effectively preventing foreign objects from entering the pump unit 4, thus effectively solving the problems existing in the prior art. Furthermore, by installing a U-shaped ring 3, a connecting rope 8, and a second counterweight 7, the second counterweight 7 is placed into the water during use. The second counterweight 7 sinks to the bottom, making it easy to pull and limit the device. The first counterweight 12, through its own gravity, allows the second filter screen 6 to be deployed, preventing it from clogging the pipes with the water flow.
