Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, specifically a floating drainage pump. Background Technology

[0002] Floating drainage pumps are mechanical devices that can float on water by buoyancy and have the extraction and drainage functions of submersible pumps. They are widely used in rivers, reservoirs, wide water areas along rivers, and urban flood control and rescue scenarios. Their core function is to pump water from low-lying areas or drainage systems and discharge it into drainage pipes or ditches, thereby reducing the impact of water accumulation on urban traffic, the environment, and residents' lives.

[0003] For example, the utility model patent with announcement number CN222558794U discloses a float-type submersible pump, which describes a pump body fixedly installed at the lower part of the support frame and float components fixedly installed on both sides of the upper end of the support frame, so that the submersible pump body can float on the water, enabling floating operation and avoiding the impact of siltation on the pump body.

[0004] During urban flood control and emergency response, due to insufficient water depth or the continuous drop in water level as the water is gradually drained, the pump body and float are integrated in the above-mentioned technical solution. When the water level is insufficient to support the pump body to float, the pump body will come into contact with the water and silt accumulation, causing the pump body to be blocked and worn, making the floating drainage pump unsuitable for drainage work in shallow water.

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a floating drainage pump that solves the problems mentioned in the background section.

[0010] Preferably, the float assembly includes symmetrically arranged float swing arms and float components. A pivot rod is fixed in the middle of the mounting bracket. The middle of the float swing arm is rotatably connected to the pivot rod. The float component is fixedly connected to the top of the float swing arm.

[0013] (III) Beneficial Effects

[0014] This utility model provides a floating drainage pump. It has the following beneficial effects:

[0015] 1. In this utility model, the drive motor rotates and pulls the drainage pump body up and down on the mounting bracket through the threaded connection, so as to adjust the height difference between the drainage pump body and the float, that is, to adjust the height difference between the drainage pump body and the water surface, so that the drainage pump can drain water normally at shallow water depths.

[0016] 2. In this utility model, the sliding crossbar can push the side wall of the sliding groove, causing the float swing arm to rotate on the pivot rod. This allows the symmetrically arranged float components to open to both sides around the pivot rod, increasing the span between the two float components and improving the overall stability. This can prevent the side tilting caused by the upward shift of the center of gravity of the drainage pump body. In addition, while increasing the span, it can also reduce the height difference between the drainage pump body and the float components, thereby achieving the purpose of adjusting the height of the drainage pump body.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model embodiment provides a floating drainage pump, such as Figure 1-3 As shown, the system includes a drainage pump body 1, a mounting bracket 2, a float assembly, and a drive motor 3. The mounting bracket 2 includes a horizontal frame and several vertically downward mounting columns. The drive motor 3 is fixedly mounted on the upper side of the horizontal frame. The output end of the drive motor 3 is connected to a vertically downward extending lifting screw 4. A vertical guide rail is provided on the outer side of the mounting columns. An assembly bracket 5 is slidably mounted on the vertical guide rail. The drainage pump body 1 is bolted to the lower side of the assembly bracket 5. A U-shaped mounting frame 6 is fixed to the upper side of the assembly bracket 5. The mounting frame 6 has a displacement cavity inside and a sliding hole at the top. The lifting screw 4 slides through the hole. The mounting frame 6 has a sliding hole extending into the displacement cavity. The upper flange of the mounting frame 6 is connected to a lifting nut 7 that is concentrically arranged with the sliding hole. The lifting nut 7 is threadedly sleeved on the lifting screw 4. The drive motor 3 drives the lifting screw 4 to rotate. Under the limiting action of the vertical guide rail, the lifting nut 7, which is threadedly engaged with the lifting screw 4, can drive the drainage pump body 1 and the mounting bracket 2 to slide up and down as a whole. This can adjust the height difference between the drainage pump body 1 and the float. With the draft of the float unchanged, the water level depth required to float the drainage pump body 1 can be reduced, so that the floating drainage pump described in this application can be used for shallower water levels and the drainage and pumping can be more thorough.

[0023] The float assembly includes symmetrically arranged float booms 8 and float components 9. The float boom 8 comprises an integrally formed horizontal beam 81, a vertical boom 82, and a curved guide rod 83. A pivot rod 10 is fixed to the middle of the mounting bracket 2. The middle of the vertical boom 82 is rotatably connected to the pivot rod 10. The horizontal beam 81 is located at the top of the vertical boom 82 and extends outward. The float component 9 is fixedly installed on the horizontal beam 81. The curved guide rod 83 is located at the bottom of the vertical boom 82 and slopes inward. The curved guide rod 83 is inclined and has a sliding groove 84. The assembly bracket 5 is equipped with a sliding crossbar 11. The sliding crossbar 11 slides through the sliding groove 84. During the process of the assembly bracket 5 sliding up and down the vertical guide rail of the mounting bracket 2, the sliding crossbar 11 will push the side wall of the sliding groove 84, which will cause the float swing rods 8 on both sides to rotate around the pivot rod 10 to adjust the span between the two float components 9, so that the center of gravity of the floating drainage pump shifts up and down to keep it stable.

[0024] Working principle:

[0025] In this invention, the buoyancy of the accumulated water will cause the float 9 to float on the water surface, and the drainage pump body 1 will be below the water surface on the mounting bracket 2 to facilitate drainage. When the water level is insufficient, the drive motor 3 can be rotated, and the assembly bracket 5 and the drainage pump body 1 can be slid upward as a whole through the threaded connection. During the sliding process, the sliding crossbar 11 will abut against and squeeze the sliding groove 84 of the float swing rod 8, causing the bending guide rod 83 of the float swing rod 8 to rotate upward, so that the float 9 fixed at the top of the float swing rod 8 opens outward, increasing the span between the float 9 on both sides, which is used to counteract the instability caused by the upward shift of the center of gravity during the upward movement of the drainage pump body 1, and to prevent the floating drainage pump from tilting.

[0026] In this application, raising the height of the drainage pump body 1 can reduce the distance between the drainage pump body 1 and the float 9, allowing for drainage of shallower water levels when the draft changes.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
