Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a recyclable basement waterproof temporary drainage system. Background Technology

[0002] In basement structural construction and waterproofing projects, temporary drainage systems are required to remove groundwater, rainwater, and other seepage and accumulation. Traditional solutions mainly include blind ditch drainage, open ditch + pump drainage, and permanent drainage board pre-embedding. Blind ditch drainage involves excavating trenches, filling them with gravel as a water-conducting layer, and covering the top with soil. However, this method has problems such as non-recyclable materials, soil pollution, and later blockage. Open ditch + pump drainage requires a continuous power supply, resulting in high maintenance costs and failing to solve the problem of water accumulation under the structural foundation. Permanent drainage board pre-embedding has high material costs, and some areas may not require drainage later, leading to waste.

[0003] When setting up temporary drainage systems, traditional gravel blind drain materials are permanently buried after use and cannot be recycled. The waste gravel pollutes the soil, resulting in serious material waste and environmental pollution. At the same time, the excavation and backfilling of blind drains take up more than 90% of the construction period, leading to low construction efficiency. Therefore, a recyclable basement waterproof temporary drainage system is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a recyclable basement waterproof temporary drainage system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a recyclable basement waterproof temporary drainage system, comprising a conical water collection trough and a PVC guide pipe. The conical water collection trough is disposed at the top of the PVC guide pipe. A filter screen is fixedly connected to the inner wall of the PVC guide pipe. A crossbeam is fixedly connected to the inner wall of the conical water collection trough. A vertical rod is fixedly connected to the inner wall of the crossbeam. A connecting pipe is fixedly connected to the inner wall of the filter screen. The bottom of the vertical rod is inserted into the inner wall of the connecting pipe. A separation mechanism is provided inside the vertical rod.

[0006] As a further description of the above technical solution: a negative pressure generator is provided on the surface of the PVC guide tube, and a pressure sensor is fixedly connected to the right side of the PVC guide tube.

[0007] As a further description of the above technical solution: a semi-circular traction ring is fixedly connected to the top of the crossbeam.

[0008] As a further description of the above technical solution: the central axis of the vertical rod coincides with the central axis of the connecting pipe.

[0009] As a further description of the above technical solution: the inner wall of the conical water collection tank is set as a downward conical slope.

[0010] As a further description of the above technical solution: the separation mechanism includes a plug rod, which is slidably connected to the inner wall of the vertical rod. A slot is provided on the inner wall of the connecting tube, and the plug rod is inserted into the inner wall of the slot.

[0011] As a further description of the above technical solution: the insertion rod is elastically connected to the inner wall of the vertical rod through a return spring.

[0012] As a further description of the above technical solution: a steel wire rope is fixedly connected to the end of the insertion rod away from the slot, and a pull rod is fixedly connected to the end of the steel wire rope away from the insertion rod. The pull rod is slidably connected to the inner wall of the vertical rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, a plug-in connection is adopted, eliminating the need for welding or threaded fixing. During disassembly, the locking mechanism is used to release the lock, allowing for quick and easy recycling of the entire device. Compared to traditional blind drain drainage methods, this reduces construction time, and the PVC guide pipes and metal components can be reused, further shortening the construction period and achieving full material recycling.

[0014] 2. In this invention, a -0.05MPa negative pressure environment is created inside the pipe using a micro turbine negative pressure generator, thereby increasing the drainage speed. A pressure sensor monitors the water pressure inside the pipe in real time. When the pressure is greater than 0.1MPa, the negative pressure enhancement mode is automatically triggered to improve drainage efficiency and prevent water accumulation and blockage.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a recyclable basement waterproof temporary drainage system, comprising a conical water collection trough 11 and a PVC guide pipe 12. The conical water collection trough 11 is located at the top of the PVC guide pipe 12. The funnel-shaped inlet of the conical water collection trough 11 quickly collects basement water and reduces splashing. The inner wall of the conical water collection trough 11 is set as a downward conical slope to facilitate water flow acceleration. A negative pressure generator 31 is provided on the surface of the PVC guide pipe 12. The PVC guide pipe 12 is a lightweight and corrosion-resistant pipe that guides the accumulated water to the downstream collection point. The negative pressure generator 31 is a micro turbine negative pressure machine that forms a micro negative pressure inside the pipe. The drainage efficiency is improved by negative pressure suction. A pressure sensor 15 is fixedly connected to the right side of the PVC guide pipe 12. A filter screen 21 with a mesh diameter of 2mm is fixedly connected to the inner wall of the PVC guide pipe 12 to intercept mud, sand and gravel, and prevent downstream equipment blockage.

[0019] Reference Figure 1 - Figure 3 A crossbeam 41, which also serves as a structural support, is fixedly connected to the inner wall of the conical water collection tank 11. A semi-circular traction ring 42 is fixedly connected to the top of the crossbeam 41. The semi-circular traction ring 42 facilitates hoisting and subsequent overall recovery, and facilitates the disassembly or movement of the entire device. A vertical rod 51 is fixedly connected to the inner wall of the crossbeam 41. A connecting pipe 52 is fixedly connected to the inner wall of the filter screen 21. The bottom of the vertical rod 51 is inserted into the inner wall of the connecting pipe 52. The central axis of the vertical rod 51 and the central axis of the connecting pipe 52 coincide, forming the central positioning axis of the filter screen 21, ensuring that the filter screen is centered and not tilted.

[0020] Reference Figure 2 - Figure 4 The vertical rod 51 is equipped with a separation mechanism 6, which includes a plug rod 63. The plug rod 63 is slidably connected to the inner wall of the vertical rod 51, and the sliding direction of the plug rod 63 is the radial direction of the vertical rod 51. The inner wall of the connecting tube 52 is provided with a slot 65 that cooperates with the plug rod 63. The plug rod 63 is inserted into the inner wall of the slot 65. The plug rod 63 is elastically connected to the inner wall of the vertical rod 51 through a return spring 64. The return spring 64 applies a spring force to the plug rod 63 away from the center of the vertical rod 51.

[0021] Reference Figure 3 and Figure 4 The end of the insertion rod 63 away from the slot 65 is fixedly connected to a non-elastic steel wire rope 62. The end of the steel wire rope 62 away from the insertion rod 63 is fixedly connected to a pull rod 61. The pull rod 61 is slidably connected to the inner wall of the vertical rod 51, and the sliding direction of the pull rod 61 is up and down.

[0022] Working Principle: During use, the conical water collection trough 11 is placed at the lowest point of the basement. The position of the conical water collection trough 11 is adjusted using the traction ring 42 to align it with the water accumulation point. The lower end of the PVC diversion pipe 12 is connected to a water collection pit or mobile water tank. When water flows through the filter screen 21, impurities such as mud and sand are intercepted, while clean water is discharged through the diversion pipe. The pressure sensor 15 monitors the water pressure in real time. When the water pressure > 0.1 MPa, the enhanced drainage mode is automatically activated, and the negative pressure generator 31 is activated, creating a -0.05 MPa negative pressure environment inside the pipe. The accumulated water flows rapidly along the conical slope and is initially purified by the filter screen 21. The pressure sensor 15 monitors the water pressure inside the pipe in real time. When the filter screen becomes clogged, causing the pressure to rise above the set threshold, an on-site audible and visual alarm prompts maintenance.

[0023] During the maintenance / recycling phase, the operator manually holds the traction ring 42 to lift the device while simultaneously pulling the lever 61. This, in turn, drives the insertion rod 63 via the wire rope 62 to overcome the inward retraction of the return spring 64. The insertion rod 63 then exits the slot 65, and the filter screen 21 loses its axial locking. It can then be pulled out entirely for cleaning or lifted out of the basement along with the device, achieving tool-free and pollution-free recyclable temporary drainage. The combination of the traction ring 42 and the crossbeam 41 further simplifies the installation and recycling of the device, enabling the recycling and reuse of drainage materials. It is suitable for temporary flood control or emergency drainage scenarios, combining high efficiency and reusability.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
