Description

Technical Field

[0001] The utility model relates to the field of bridge engineering, in particular to drainage equipment used in bridge engineering. Background Art

[0002] According to the patent office database search, the publication number CN219508366U is a bridge drainage device. The positioning column is used to facilitate the positioning of the water collection frame, thereby avoiding the phenomenon of the water collection frame being offset in the foundation pit. The handle is provided to take out the cover plate from the inside of the water collection frame, and the pull rod is used to take out the filter from the inside of the water collection frame and clean it, thereby effectively solving the problem that when rainwater and debris flow into the drainage pipe, the inside of the discharge pipe is prone to blockage, thereby improving the practicality of the bridge drainage device. However, the drainage device is only convenient for taking out the filter from the inside of the water collection frame for cleaning. Since workers cannot always stay next to the drainage device on rainy days and there are many drainage devices, it is still easy for debris to enter the inside of the water collection frame from the strip opening to cause internal blockage;

[0003] Therefore, it is necessary to invent a drainage device for bridge engineering. Utility Model Content

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] like Figure 1-Figure 6,

[0020] It includes a drainage box 1, a drainage box 2 11 and a drainage pipe 12. The drainage box 2 11 is installed at the bottom of the drainage box 1. The drainage pipe 12 is connected to the bottom of the drainage box 2 11. The drainage box 1 and the drainage box 2 11 are provided with a drainage component 2 inside. The drainage component 2 can avoid drainage blockage in bridge engineering.

[0021] The drainage assembly 2 includes a supporting mesh box 26 and a filter mesh cylinder 27. The supporting mesh box 26 is installed inside the lower end of the drainage box 11. The supporting mesh box 26 is used to support and install the filter mesh cylinder 27. The filter mesh cylinder 27 is clamped in the supporting mesh box 26. The filter mesh cylinder 27 is used to support and place the garbage in the rainwater after filtering. The upper end diameter of the filter mesh cylinder 27 is smaller than the water outlet at the bottom of the water guide inner cover 21. The water guide inner cover 21 can be pulled upward from the supporting mesh box 26. The inside of the drainage box 1 is equipped with a water guide inner cover 21 through bolts. The water guide inner cover 21 is used to guide the rainwater entering the drainage box 1. The inner wall of the water guide inner cover 21 is installed with a guide rod 24. The guide rod 24 is used to guide the rainwater entering the water guide inner cover 21, so that the rainwater is spiral The water enters the filter screen cylinder 27 in a vortex shape, and the guide rod 24 is obliquely arranged on the inner wall of the water guide inner cover 21. A support ring 22 is installed on the upper end of the water guide inner cover 21. The support ring 22 and the connecting rod 23 are used to connect and support the protective top cover 25. A connecting rod 23 is installed on the upper end of the support ring 22, and a support plate 28 is inserted on the connecting rod 23. A protective top cover 25 is installed on the upper end of the support plate 28. The height distance between the bottom of the protective top cover 25 and the drainage box 1 is fixed, which is convenient for rainwater to quickly flow into the drainage box 1. The mesh on the protective top cover 25 is used to prevent large-volume debris such as plastic bags from entering the drainage box 1. The protective top cover 25 is in the shape of a quadrangular pyramid. The protective top cover 25 is arranged on the top of the drainage box 1, and the protective top cover 25 is positioned by a nut.

[0022] The working principle of the utility model is as follows: a support net box 26 is installed inside the lower end of the drainage box 11, a filter net cylinder 27 is clamped in the support net box 26, a water guide inner cover 21 is installed inside the drainage box 1 by bolts, a guide rod 24 is installed on the inner wall of the water guide inner cover 21, the guide rod 24 is tilted on the inner wall of the water guide inner cover 21, a support ring 22 is installed on the upper end of the water guide inner cover 21, a connecting rod 23 is installed on the upper end of the support ring 22, and a support rod 23 is inserted on the connecting rod 23. The support plate 28 is provided with a protective top cover 25 on the upper end of the support plate 28. The protective top cover 25 is in the shape of a quadrangular pyramid and is arranged on the top of the drainage box 1. The protective top cover 25 is positioned by a nut to prevent large-volume debris such as plastic bags from entering the drainage box 1. The height distance between the bottom of the protective top cover 25 and the drainage box 1 is fixed, so that rainwater can quickly flow into the drainage box 1. Rainwater and small-volume debris enter the inner side of the water guide inner cover 21 and pass through the protective top cover 25. The water guide inner cover 21 guides the rainwater entering the drainage box 1, and guides the rainwater entering the water guide inner cover 21 through the guide rod 24, so that the rainwater enters the filter screen cylinder 27 in a vortex shape, and the filter screen cylinder 27 is supported and installed by the support screen box 26. Rainwater and small-volume debris enter the filter screen cylinder 27, and the filter screen cylinder 27 filters the rainwater, so that the small-volume garbage in the rainwater stays in the filter screen cylinder 27 after filtering. A plurality of drainage equipment are arranged on the bridge project, and the small-volume garbage cannot cause the filter screen cylinder 27 to be blocked. The rainwater flows out of the filter screen cylinder 27, enters the support screen box 26, and then enters the drainage box 2 11, and is finally discharged through the drainage box 2 11. After the rain, the protective top cover 25 is first removed, and then the water guide inner cover 21 is removed, and the filter screen cylinder 27 can be pulled out upwards to clean the garbage in the filter screen cylinder 27, so that the drainage equipment of the bridge project will not only not block the drain outlet and the inside of the drain pipe on rainy days, but also can collect the garbage for subsequent treatment.
