[0002] With the continuous development of transportation, the requirements for road drainage systems are getting higher and higher. If the drainage is not smooth, it will cause water accumulation on the road, affecting driving safety and comfort. At the same time, it will accelerate the damage of the road surface and reduce the service life of the road surface. It also wastes time during installation and disassembly. Therefore, we need to design precast concrete road drainage ditch covers with a snap-on structure and a detachable collection basket structure. The snap-on structure makes the installation process of the cover simple. During road construction or drainage ditch maintenance, workers do not need to use complicated tools and spend a lot of time on installation. They only need to align the cover with the position of the drainage ditch. The cover can be quickly fixed by the snap-on action of the snap, shortening the construction time. The collection basket can prevent the drainage ditch from being blocked, thereby improving installation efficiency and service life. Utility Model Content

[0023] Hereinafter, embodiments of the precast concrete pavement drainage ditch cover of the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1-5The present invention shows a precast concrete pavement drainage ditch cover according to an embodiment of the present invention, which includes a cover plate 2 arranged on the top of the drainage ditch 1. A plurality of anti-skid ridges 3 are fixedly installed on the top of the cover plate 2. Through the arrangement of the anti-skid ridges 3, the surface of the pavement cover plate 2 becomes slippery easily in rainy days or humid environments. When pedestrians walk on it, if the cover plate 2 is not protected by the anti-skid ridges 3, they are likely to slip and get injured. The anti-skid ridges 3 can increase the friction force on the surface of the cover plate 2, so that the soles of pedestrians can better grip the ground and reduce the risk of slipping. A collection basket 4 is provided at the bottom of the cover plate 2, and slide rails are fixedly connected to the left and right sides of the bottom of the cover plate 2. 5. The two sides of the two slide rails 5 facing each other are slidably connected with a sliding block 6. The sliding block 6 is slidably connected to the collection basket 4. Through the coordinated use of the slide rail 5 and the sliding block 6, when the sliding block 6 slides in the inner cavity of the slide rail 5, the sliding block 6 plays a guiding role on the collection basket 4 during the sliding process, ensuring that the collection basket 4 will not shift its position during installation, thereby improving the stability of the collection basket 4 when in use. The central axis on the left and right sides of the top of the cover plate 2 is fixedly connected with a fixing block 7. The tops of the left and right sides of the inner cavity of the drain ditch 1 are fixedly connected with a limiting groove 8. The limiting groove 8 is adapted to the fixing block 7. The four corners of the top of the inner cavity of the drain ditch 1 are fixedly connected with The fixing plate 9 is fixedly connected to the top of the fixing plate 9 with a card slot 10, and the four corners of the bottom of the drain ditch 1 are fixedly connected to the connecting plate 11. The left and right sides of the connecting plate 11 are fixedly connected to the fixing frame 12. The inner cavity of the two fixing frames 12 is provided with a sliding rod 14. The opposite side of the inner cavity of the two fixing frames 12 is fixedly connected with a fixing sleeve 13. The sliding rod 14 is slidably connected to the inner cavity of the fixing sleeve 13. One end of the sliding rod 14 is fixedly connected with a buckle 15. The two buckles 15 are engaged with the card slot 10. The surface of the fixing sleeve 13 and the sliding rod 14 is provided with a spring 16. The two ends of the spring 16 are respectively connected to the inner cavity of the fixing frame 12 and the sliding The movable rod 14 is welded, and the surface of the limit slot 8 is provided with two symmetrical grooves for the fixing block 7 to engage. Through the setting of the spring 16, the spring 16 is in a compressed state in the slot 10 and the buckle 15, and can generate a certain elastic force. When the buckle 15 is inserted into the slot 10, the elastic force of the spring 16 acts on the buckle 15, so that the buckle 15 is tightly stuck in the slot 10, thereby ensuring that the cover plate 2 is firmly fixed on the drain ditch. Even under the action of external forces such as vehicles driving or pedestrians stepping on it, the cover plate 2 will not loosen or shift easily. The staff can quickly disassemble the cover plate 2 for cleaning and maintenance, and then easily install it back.

[0025] When the user presses the slider 6 on the bottom of the drain ditch 1, the user can slide the slider 6 in the inner cavity of the slide rail 5, so that the collection basket 4 is installed on the top of the cover plate 2, and the garbage leaking from the ground into the bottom of the cover plate 2 is collected, ensuring that the drain ditch 1 will not be blocked during use. Then the cover plate 2 is placed on the top of the drain ditch 1, and then the buckle 15 slides on both sides of the card slot 10, and then the buckle 15 is engaged with the card slot 10, so that the buckle 15 drives the sliding rod 14 to slide in the inner cavity of the fixing sleeve 13, and then the spring 16 on the surface of the fixing sleeve 13 and the sliding rod 14 will elastically shorten. When the buckle 15 is tightly stuck on both sides of the card slot 10, the spring 16 will elastically rebound, and the sliding rod 14 will slide in the inner cavity of the buckle 15, and the fixing block 7 will be stuck in the inner cavity of the two square grooves of the limit slot 8, and finally the drain ditch 1 and the cover plate 2 are quickly installed.

[0026] To sum up: the precast concrete pavement drainage ditch cover plate, through the coordinated use of the card slot 10, the buckle 15 and the spring 16, makes the drainage ditch 1 and the cover plate 2 fit tightly together, so that the drainage ditch 1 and the cover plate 2 will not waste time during installation, and then through the coordinated use of the collection basket 4, the slide rail 5 and the sliding block 6, the garbage on the ground can be concentrated in the inner cavity of the collection basket 4, thereby achieving the purpose of adopting the buckle structure and the detachable collection basket structure. The buckle structure makes the installation process of the cover plate simple. During road construction or drainage ditch maintenance, the staff does not need to use complicated tools and spend a lot of time on installation. They only need to align the cover plate with the position of the drainage ditch, and the cover plate can be quickly fixed by the snap action of the buckle, which shortens the construction time. The collection basket can prevent the drainage ditch from being blocked, thereby improving the installation efficiency and service life.
