Description

Technical Field

[0001] This application relates to the field of drainage equipment technology, and in particular to a drainage device for hydraulic construction. Background Technology

[0002] Drainage is a crucial aspect of water conservancy project construction, typically achieved by pumping water from the construction area to the outside. Currently, the common method involves directly submerging the pump's inlet pipe in the water. However, because the inlet pipe usually contacts the bottom of the water body, which often accumulates silt and debris, the inlet pipe is prone to blockage, leading to decreased pump efficiency, potential equipment damage, delayed construction, and increased maintenance costs. Therefore, a water conservancy construction drainage device is proposed. Utility Model Content

[0003] To address the problem that the inlet pipe is usually in direct contact with the bottom of the water body during drainage, and that the bottom of the water body often accumulates a large amount of silt and debris, making the inlet pipe opening easy to be blocked by silt, this application provides a drainage device for hydraulic construction.

[0004] The hydraulic construction drainage device provided in this application adopts the following technical solution:

[0005] A drainage device for hydraulic construction includes a water pump, a drainage pipe is fixedly connected to the connection port of the water pump, a counterweight and a cover are provided at the water inlet end of the drainage pipe, the counterweight is connected to the drainage pipe through a connecting mechanism, and a moving mechanism is provided between the cover and the counterweight, the moving mechanism causing the cover to move relative to the drainage pipe.

[0006] Preferably, the connecting mechanism includes a fixed base, the upper end of which is fixedly sleeved on the outer surface of the drain pipe, the fixed base is hollow inside, and the surface of the fixed base is provided with uniformly distributed filter holes, and the lower end of the fixed base is fixedly connected to the counterweight.

[0007] Preferably, the inlet end of the drain pipe is located inside the fixed base.

[0008] Preferably, the moving mechanism includes a float fixedly installed on the top of the cover, the closed end of the cover faces upward and has an opening adapted to the fixed seat, the fixed seat is slidably installed inside the closed end opening of the cover, and an elastic element is provided between the open end of the cover and the counterweight.

[0009] Preferably, the elastic element includes cylindrical grooves formed on both sides inside the cover, a guide rod is slidably connected inside the cylindrical groove, the guide rod is T-shaped, the lower end of the guide rod extends through to the outside of the cover and is fixedly connected to the counterweight, a spring is sleeved on the outer surface of the guide rod, the upper end of the spring is fixedly connected to the guide rod, and the lower end of the spring is fixedly connected to the inner surface of the cylindrical groove.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention, through the combination of a cover, a counterweight, and a moving mechanism, ensures that the drain pipe is at a high water level during the pumping process, preventing the drain pipe from contacting the silt at the bottom of the water and thus achieving a good anti-clogging effect.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a drainage device for water conservancy construction, including a water pump 1. A drainage pipe 2 is fixedly connected to the connection port of the water pump 1. A counterweight 3 and a cover 5 are provided at the water inlet end of the drainage pipe 2. The counterweight 3 is connected to the drainage pipe 2 through a connecting mechanism. A moving mechanism is provided between the cover 5 and the counterweight 3. The moving mechanism causes the cover 5 to move relative to the drainage pipe 2.

[0018] Furthermore, the connecting mechanism includes a fixed seat 4, the upper end of which is fixedly sleeved on the outer surface of the drain pipe 2. The fixed seat 4 is hollow inside, and the surface of the fixed seat 4 is provided with evenly distributed filter holes. The lower end of the fixed seat 4 is fixedly connected to the counterweight 3.

[0019] Furthermore, the inlet end of the drain pipe 2 is located inside the fixed base 4.

[0020] In this embodiment, when the water pump 1 starts working, water is drawn through the drain pipe 2. The inlet end of the drain pipe 2 is located inside the fixed base 4. The surface of the fixed base 4 is evenly distributed with filter holes. Water can enter the fixed base 4 through the filter holes, while larger debris and silt are blocked outside the fixed base 4, thereby effectively preventing clogging problems.

[0021] Furthermore, the moving mechanism includes a float 6 fixedly installed on the top of the cover 5. The closed end of the cover 5 faces upward and has an opening adapted to the fixed seat 4. The fixed seat 4 is slidably installed inside the closed end opening of the cover 5. An elastic element is provided between the open end of the cover 5 and the counterweight 3.

[0022] Furthermore, the elastic element includes cylindrical grooves 9 formed on both sides inside the cover 5. A guide rod 8 is slidably connected inside the cylindrical groove 9. The guide rod 8 is T-shaped. The lower end of the guide rod 8 extends through to the outside of the cover 5 and is fixedly connected to the counterweight 3. A spring 7 is sleeved on the outer surface of the guide rod 8. The upper end of the spring 7 is fixedly connected to the guide rod 8, and the lower end of the spring 7 is fixedly connected to the inner surface of the cylindrical groove 9.

[0023] In this embodiment, the cover 5 is connected to the counterweight 3 via a moving mechanism. A float 6 is provided on the top of the cover 5 to ensure that the top of the cover 5 is at the water surface, while the counterweight 3 is held below the water surface by gravity, causing relative sliding displacement between the cover 5 and the fixed base 4. Water can then be drawn out through the filter holes by the drain pipe 2. By coordinating the cover 5, counterweight 3, and moving mechanism, the drain pipe 2 is kept at a higher water level during the pumping process, preventing it from contacting the bottom silt. Furthermore, when all the water is pumped out, the buoyancy disappears, the spring 7 returns to its original position, and the cover 5 covers the outer surface of the drain pipe 2 and the fixed base 4, further protecting the drain pipe 2.
