Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction drainage structure. Background Technology

[0002] During construction, especially in basements, foundations, or during the rainy season, a large amount of construction wastewater, rainwater, and groundwater seepage will be generated. If these are not drained in time, they will affect the construction progress and project quality, and may even lead to safety hazards such as foundation pit collapse and foundation settlement.

[0003] Currently, when using existing water pumps for drainage, the presence of numerous debris and impurities at construction sites can easily draw these into the pumps, causing blockages. Therefore, to better address drainage blockages during construction, promote technological advancements in the industry, and enhance core technological competitiveness, this application proposes a novel implementation scheme for construction drainage devices that differs from existing technologies. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of the lack of anti-clogging in existing building construction drainage structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A building construction drainage structure includes an inlet cylinder with an installation port on its circumference. An inner filter screen is fitted into the installation port, and an outer filter screen is installed outside the inner filter screen. An installation plate is fixedly connected between the inner walls of the inlet cylinder. The installation plate has multiple water inlet holes, and an installation box is fitted to the top of each water inlet hole. An outlet hole is provided on one side of the installation box. A rotating rod is rotatably mounted on the installation plate via an embedded bearing. Two mounting brackets are fixedly connected to the top of the rotating rod, and multiple arc-shaped plates are fixedly connected between the two mounting brackets. The bottom end of the rotating rod extends through the bottom of the inlet cylinder and is fixedly connected to a fixing rod. Both ends of the fixing rod are fixedly connected to brushes that contact the inner filter screen and are located between the inner and outer filter screens.

[0006] Furthermore, multiple connecting blocks are fixedly connected to the outer circumference of the water inlet cylinder, and connecting rods are rotatably inserted into the bottom of the connecting blocks.

[0007] Furthermore, a base is fixedly connected to the bottom of the outer filter screen, and the bottom end of the connecting rod is threadedly connected to the base.

[0008] Furthermore, a flange is fixedly connected to the top of the water inlet cylinder.

[0009] Furthermore, the mounting box is tilted at an angle of 45 degrees.

[0010] The beneficial effects of this utility model are as follows: 1. Large debris such as tree branches and plastic bags are removed from rainwater through the outer filter screen. Then, medium and large impurities such as sand, soil particles, and small construction debris are removed from rainwater through the inner filter screen, thereby preventing impurities from being sucked into the water pump and causing blockage.

[0011] 2. By flushing the arc-shaped plate with water, the mounting bracket rotates, which in turn drives the brush to rotate. This causes the brush to move on the inner filter screen, removing impurities adhering to the screen and preventing them from clogging the mesh of the inner silicon material screen, thus affecting drainage efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A building construction drainage structure includes an inlet cylinder 1 with an installation port on its circumference. An inner filter screen 7 is snapped into the installation port. The inner filter screen 7 is made of high-density metal mesh with a mesh diameter of 2-5mm, which can intercept medium and large impurities such as sand and gravel. An outer filter 6 is provided on the outside of the inner filter 7. The outer filter 6 uses a low-density mesh with a mesh diameter of 10-15mm, which can first intercept large debris such as tree branches and plastic bags to prevent them from clogging the inner filter. An installation plate 8 is welded between the inner circumference of the water inlet cylinder 1. The installation plate 8 is provided with multiple water inlet holes 9. The top of the water inlet hole 9 is snapped with an installation box 15. The installation box 15 is tilted at an angle of 45 degrees. An outlet hole 16 is provided on one side of the installation box 15. A rotating rod 10 is rotatably mounted on the mounting plate 8 via an embedded bearing. Two mounting brackets 13 are welded to the top of the rotating rod 10, and multiple arc-shaped plates 14 are welded between the two mounting brackets 13. The bottom end of the rotating rod 10 passes through the bottom of the water inlet cylinder 1 and is fixed to a fixing rod 11 by bolts. Both ends of the fixing rod 11 are fixed with brushes 12 by bolts. The bristles of the brushes 12 are made of wear-resistant nylon material with moderate hardness. The bristles of the brushes 12 can extend into the mesh of the inner filter screen 7. The brushes 12 are in contact with the inner filter screen 7, and the brushes 12 are located between the inner filter screen 7 and the outer filter screen 6. The fixing rod 11 will not come into contact with the outer filter screen 6. The water flow washes over the arc plate 14, causing the mounting bracket 13 to rotate, which in turn causes the rotating rod 10 and the fixed rod 11 to rotate, which in turn causes the brush 12 to rotate. As a result, the brush 12 brushes on the inner filter screen 7, thereby removing impurities adhering to the inner filter screen 7 and further preventing impurities from clogging the mesh of the inner filter screen 7.

[0016] Multiple connecting blocks 3 are welded to the outer circumference of the water inlet cylinder 1. A connecting rod 4 is inserted into the bottom of the connecting block 3 through a bearing. A base 5 is welded to the bottom of the outer filter screen 6. The bottom end of the connecting rod 4 is threaded to the base 5. Tighten the connecting rod 4 to loosen it from the base 5, and then remove the base 5 to remove the outer filter screen 6, thus facilitating the maintenance of the outer filter screen 6 and the inner filter screen 7.

[0017] A flange 2 is welded to the top of the inlet cylinder 1, which facilitates the connection between the inlet end of the water pump and the inlet cylinder 1.

[0018] The working principle of this embodiment is as follows: When in use, the water inlet end of the water pump is connected to the water inlet cylinder 1 through the flange 2. Under the suction of the water pump, the rainwater flows towards the water inlet cylinder 1. The rainwater first passes through the outer filter screen 6 to remove large debris such as branches and plastic bags. Then, the rainwater passes through the inner filter screen 7 to remove medium and large impurities such as sand, soil particles, and small construction debris. Next, the rainwater enters the mounting box 15 from the water inlet hole 9 and is discharged from the water outlet hole 16. Finally, it is discharged from the water outlet end of the water pump. During this process, the discharged water flows onto the arc plate 14, causing the mounting bracket 13 to rotate, which in turn causes the rotating rod 10 and the fixed rod 11 to rotate, which in turn causes the brush 12 to rotate. As a result, the brush 12 brushes on the inner filter screen 7, thereby removing impurities adhering to the inner filter screen 7 and further preventing impurities from clogging the mesh of the inner silicon material screen 7. The water continues to flow upwards, rising from the holes on the mounting bracket 13 and flowing into the upper part of the inlet cylinder 1, where it is drawn away through the flange 2. When it is necessary to inspect and maintain the external filter 6 and the internal filter 7, turn the connecting rod 4 to loosen it from the base 5, and then remove the base 5 to remove the external filter 6, thus facilitating the inspection and maintenance of the external filter 6 and the internal filter 7.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
