Description

Technical Field

[0001] The invention relates to the technical field of filtration for highway drainage, and in particular to a filtration structure for highway drainage pipe network engineering design. Background Art

[0002] In highway drainage pipe network projects, the filtration structure is a very critical part of the design. Its main function is to prevent a large amount of sediment and debris from entering the pipe network system, ensure the smooth flow of the drainage system and its long-term effective operation, while improving the drainage water quality and reducing pipe blockage, sedimentation and other problems.

[0003] The existing highway drainage network engineering filtration structure usually sets one or more grilles made of metal, plastic and other materials at the entrance of the drainage network. This grille can effectively block large debris such as stones, garbage, dead leaves, etc., thereby reducing their blockage of the drainage network. However, in actual use, when the amount of rainwater on the road is large, the flowing water will drive floating plastic bags and other garbage to rush towards the grille. After the plastic bag garbage is blocked by the grille, it will affect drainage. Moreover, the blocked grille is hidden underwater and is difficult to find and deal with, which causes water accumulation and reduces the efficiency of highway drainage.

[0004] In summary, the existing technology lacks automatic anti-blocking technology in highway drainage gratings. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the background technology and propose a filtering structure for highway drainage network engineering design.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a filtering structure for highway drainage network engineering design, including a drainage pipe, a water pipe is connected and fixedly arranged on the drainage pipe, a drainage trough is connected and fixedly arranged on the water pipe, a grille is slidingly arranged in the drainage trough, a warning rod is rotatably connected and arranged on the grille, a filtering fence is connected and fixedly arranged at the bottom of the grille, an anti-blocking mechanism is connected and fixedly arranged on the filter fence, a lifting mechanism is connected and fixedly arranged in the drainage trough, and a suction transmission mechanism is installed and fixedly arranged in the water pipe.

[0011] Preferably, the anti-blocking mechanism includes a plurality of fixing frames, the fixing frames are fixedly connected to the filter fence, a guide rod is fixedly connected to the fixing frames, a reciprocating screw is rotatably connected to the fixing frames, and a transmission wheel is fixedly connected to one end of the reciprocating screw.

[0012] Preferably, a moving frame is slidably provided on the outer wall of the reciprocating screw rod, the bottom end of the moving frame is slidably provided on the guide rod, and an anti-blocking rod is fixedly connected to the moving frame.

[0013] Preferably, the lifting mechanism includes an electric push rod, which is fixedly connected to the inner wall of the drainage groove, and the output end of the electric push rod is fixedly connected to a mounting seat, and the inner walls on both sides of the mounting seat are slidably fitted with clamping blocks, the inner end of the clamping block is fixedly connected to the inner wall of the mounting seat through a spring, the top of the clamping block is provided with an inclined surface, the mounting seat and the clamping block are movably connected to the mounting sleeve, and the clamping block is in sliding contact with the inclined surface of the handle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the grille is used to filter the highway drainage network, when the drainage volume is large, the grille can be lifted up by the lifting mechanism, and the filter fence can be used for multi-directional filtering to avoid blockage by plastic bag garbage. At the same time, when the grille is lifted, the warning pole will automatically stand up to remind passing vehicles and pedestrians to pay attention to changes in the surrounding environment to avoid unnecessary safety hazards; By setting up an anti-blocking mechanism, when the drainage volume is large and the grille is lifted for filtration, the water passing through the water pipe will drive the impeller to rotate, thereby driving multiple anti-blocking rods to move back and forth, pushing the plastic bag garbage blocked outside the filter fence, which can significantly improve the working efficiency of the drainage system and reduce garbage blockage. Especially in the case of heavy rain and high drainage demand, it can automatically adapt to drainage conditions, reduce manual intervention, and provide a more efficient and environmentally friendly drainage solution; By setting a water storage tank in the drainage pipe, water can be stored. Then, when it is not raining, the impeller can rotate to suck the dust generated by vehicles driving on the road into the drainage pipe, and the arc-shaped spray pipe can be used to spray water mist to filter the dust particles in the air, thereby improving the practicality of the device.
