Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a filtering and drainage pipeline for water conservancy projects. Background Art

[0002] In water conservancy projects, it is often necessary to dredge and regulate water flow through drainage pipes, but in order to filter impurities inside the pipes, a filtering mechanism is usually set inside the pipes. After searching, the Chinese patent announcement number CN213725215U discloses a drainage pipe that is easy to filter for water conservancy projects. Although the pipe is provided with a main threaded sleeve, a secondary threaded sleeve and a threaded rod, and the main threaded sleeve and the secondary threaded sleeve are rotated to facilitate the disassembly and installation of the main fixer and the secondary fixer, and the installation and disassembly of the connecting pipe is convenient, and a telescopic rod, a main baffle and a secondary baffle are provided to facilitate the disassembly and installation of the filter screen, the device mainly realizes the connection between pipes through fasteners such as threaded rods. When cleaning the filter screen, it is still necessary to use tools to loosen the threaded rod, which reduces the convenience of cleaning the filter screen. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a filtering and drainage pipe for a water conservancy project, which solves the problem proposed in the background technology that the existing pipe connections are mainly connected to each other through fasteners such as threaded rods, and when the filter is removed and cleaned, it is still necessary to use external tools to loosen the threaded rods, which reduces convenience.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a water conservancy project filtration and drainage pipe, including a device body, a filter plate, a slider and a pressure plate, drainage pipes are provided at both ends of the device body, the interior of the device body is a hollow structure, the ends of the drainage pipes are connected to the device body by bolts, a slider is provided inside the device body, a filter plate is provided at the bottom of the slider, a groove is provided at the top of the slider, a handle is provided inside the groove, one side of the top of the device body is rotatably connected to one end of the top cover by a hinge, and the other end of the top cover is connected to the device body by a buckle.

[0005] Preferably, circular holes are provided on both sides of the bottom of the device body, and the circular holes on both sides of the bottom of the device body are aligned with the holes at the bottom of the slider, and the inner walls of the holes at the bottom of the slider are welded to the outer walls of the filter plate, thereby facilitating that the filter plate can be fixed inside the slider without affecting the up and down sliding of the slider.

[0006] Preferably, the filter plate surface is evenly distributed with filter holes, and the filter plate surface has a multi-curved structure, and the two side surfaces of the filter plate are flush with the two side surfaces of the slider. By setting the filter plate inside the slider to have a multi-curved structure, the filtration area is greatly increased compared to the circular filter plate, thereby extending the cleaning cycle of the filter plate.

[0007] Preferably, the outer wall of the slider and the inner wall of the top of the device body are tightly fitted to each other, and the outer wall surface of the slider is in sliding contact with the inner wall surface of the device body. The outer wall surface of the slider is provided with a rubber coating, and the rubber coating further improves the sealing between the slider and the inner wall of the device body, which is conducive to avoiding internal water leakage.

[0008] Preferably, the inner edge of the top of the device body is stepped, and the shape of the top of the device body matches the shape of the bottom of the sealing gasket. The sealing gasket is bonded to the surface of the pressure plate, which helps the sealing gasket to better fit the top of the device body for sealing.

[0009] Preferably, the top of the pressure plate is welded to one end of the telescopic rod, and the other end of the telescopic rod is welded to the inside of the top cover. A spring is mounted on the outside of the telescopic rod. When the top cover is closed, it drives the sealing gasket to seal the top of the device body. At the same time, the spring will be compressed. When the spring is compressed, it can compensate for the downward pressure on the sealing gasket, thereby allowing the sealing gasket to always fit and seal with the top of the device body.

[0010] The utility model provides a filtering drainage pipe for a water conservancy project, which has the following beneficial effects:

[0011] (1) A water conservancy project filtration drainage pipe, when cleaning the filter plate, the top cover can be opened by unfastening the buckle, and after the top cover is opened, the slider can be pulled out from the top of the device body by pulling the handle on the top of the slider, so that the slider can take out the filter plate, so as to clean the filter plate. After cleaning, the filter plate can be re-fixed by inserting the slider into the inside of the device body, and then the top cover is closed and fixed by the buckle. The filter plate inside the pipe does not need to be cleaned with the help of tools, which greatly improves the convenience of cleaning the filter net.

[0012] (2) This kind of water conservancy project filtration and drainage pipe greatly increases the filtration area compared with the circular filter plate by setting the filter plate inside the slider into a multi-curved structure, thereby extending the cleaning cycle of the filter plate, thereby reducing the cleaning burden of the filter plate inside the pipe, and when the top cover is closed, the sealing gasket will drive the sealing gasket to seal the top of the device body, and the spring will be compressed at the same time. When the spring is compressed, it can compensate for the downward pressure on the sealing gasket, so that the sealing gasket can always fit and seal with the top of the device body.

[0013] This solves the problem that existing pipe connections are mainly connected to each other through fasteners such as threaded rods, and when the filter is removed and cleaned, the threaded rods still need to be loosened with the help of external tools, which reduces convenience.
