AI Technical Summary
The existing overflow pipe has a single function, which can only discharge excess wastewater and lacks anti-clogging and clogging detection functions.
A sliding column and a cover are installed on the overflow pipe. Combined with a distance sensor, the sliding column moves upward to trigger an alarm when blocked, and the blockage is cleared through the drainage pipe to prevent debris from entering and to detect blockages in a timely manner.
It prevents overflow pipe blockage, detects and alarms in a timely manner, ensures unobstructed pipeline flow, and reduces maintenance time.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline overflow technology, specifically to a pipeline overflow device. Background Technology
[0002] A pipeline overflow device is a device used to control the liquid level or pressure of fluid in a pipeline to prevent fluid from overflowing or the pipeline pressure from being too high. When the liquid flow rate in the pipeline exceeds the design flow rate or an abnormal situation occurs that causes the liquid level to rise, the overflow device can discharge the excess liquid in time to prevent the liquid from flowing back in the pipeline.
[0003] In building drainage pipes, overflow pipes are usually installed to prevent sewage from flowing back into the user's house due to pipe blockage. When the pipe is blocked, excess wastewater will be discharged directly from the overflow pipe, thus preventing backflow and allowing for timely unblocking of the pipe. However, in practice, overflow pipes are mostly single-function, only capable of discharging excess wastewater. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The technical problem this invention aims to solve is that most overflow pipes have limited functions, only capable of discharging excess wastewater.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pipe overflow device, including a pipe, an overflow pipe connected to the pipe, a truncated cone on the overflow pipe, a plurality of fixed columns on the truncated cone, a sliding column on the fixed column, a cover that cooperates with the overflow pipe on the bottom surface of the sliding column, an extension rod on the fixed column, and a distance sensor that cooperates with the sliding column on the bottom surface of the extension rod.
[0008] As an improvement, the overflow pipe is L-shaped, and a drain pipe connected to it is provided, with a sealing cap threaded onto the drain pipe.
[0009] As an improvement, the fixed column is provided with a limiting column to limit the movement of the sliding column.
[0010] As an improvement, the upper surface of the cylindrical platform is a trapezoidal structure.
[0011] As an improvement, one of the limiting posts is provided with an extension post, and the extension rod is fixedly mounted on the extension post.
[0012] As an improvement, both the sliding column and the shielding cover are made of polyethylene material.
[0013] (III) Beneficial Effects
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] By installing a sliding column and a shield at the end of the overflow pipe, external debris can be prevented from entering the overflow pipe and causing blockage. At the same time, when the pipe is blocked and water enters the overflow pipe, the water flow pushes the shield upward. The distance sensor detects the upward movement of the sliding column and issues an alarm to quickly transmit information about the pipe blockage, enabling immediate repairs.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] As per the instructions Figures 1 to 3 As shown, a pipe overflow device includes a pipe 1, an overflow pipe 2 connected to the pipe 1, a frustum 3 on the overflow pipe 2, a plurality of fixed posts 4 on the frustum 3, a sliding post 5 slidably mounted on the fixed post 4, a cover 6 on the bottom surface of the sliding post 5 that cooperates with the overflow pipe 2, an extension rod 7 on the fixed post 4, and a distance sensor 8 on the bottom surface of the extension rod 7 that cooperates with the sliding post 5. The sliding post 5 and the cover 6 are both made of polyethylene material and are lightweight.
[0023] As per the instructions Figures 2 to 4 As shown, the overflow pipe 2 is L-shaped, and a drain pipe 9 connected to it is provided on the overflow pipe 2. A sealing cap 10 is threadedly connected to the drain pipe 9.
[0024] The fixed column 4 is provided with a limiting column 11 to limit the sliding column 5. By setting the limiting column 11, the excessive impact of water flow can prevent the sliding column 5 from falling off the fixed column 4.
[0025] The upper surface of the frustum 3 is a trapezoidal structure, which can prevent water from accumulating on the frustum 3.
[0026] One of the limiting posts 11 is provided with an extension post 12, and the extension rod 7 is fixedly installed on the extension post 12.
[0027] In practical use, when pipe 1 is not blocked, the shield 6 is attached to the end of overflow pipe 2, which can prevent external debris from falling into overflow pipe 2. When pipe 1 is blocked, wastewater will enter overflow pipe 2. Under the thrust of the water, the shield 6 moves away from the end of overflow pipe 2 and slides on the fixed column 4. The sliding column 5 gradually approaches the distance sensor 8. At this time, the distance sensor 8 detects the sliding column 5 and issues an alarm, thereby notifying maintenance personnel to carry out maintenance as soon as possible.
