[0052] The drainage well 11 is arranged on both sides of the road surface 10, and the drainage well 11 is arranged adjacent to the road rock 20, and the well cover 12 is arranged on the opening of the drainage well 11, and a plurality of drainage holes 121 are arranged on the well cover 12, so that the accumulated water on the road surface 10 can pass through the drainage holes 121 and enter the drainage well 11.

[0053] The filter screen 13 is arranged in the drainage well 11, and the filter screen 13 is arranged in parallel on the lower side of the well cover 12, and the filter screen 13 is arranged in a spaced manner with the well cover 12, and the height of the filter screen 13 is higher than the upper surface of the sunken green belt 30, and the filter screen 13 is used for filtering the leaves, plastic bags and other sundries in the accumulated water.

[0054] The road rock 20 is provided with a sewage channel 21 which extends obliquely downward from the side wall of the drainage well 11 to the upper side of the sunken green belt 30. The scraper 40 abuts against the upper side of the filter screen 13 and can slide on the upper side of the filter screen 13. The scraper 40 initially abuts against the side wall of the drainage well 11 away from the sewage channel 21. The power mechanism 50 is arranged in the drainage well 11 and is used to drive the scraper 40 to slide towards the sewage channel 21 so as to push the leaves, plastic bags and other sundries accumulated on the filter screen 13 into the sewage channel 21. When the water flow in the drainage well 11 is large, part of the accumulated water flows into the sunken green belt 30 from the sewage channel 21, and the leaves, plastic bags and other sundries in the sewage channel 21 are also transported into the sunken green belt 30.

[0055] With reference to Figure 2 With reference to Figure 3 The two sides of the scraper 40 are fixed with two guide columns 41 which have the same vertical axis. Two guide grooves 14 are arranged on the two opposite side walls of the drainage well 11 and are arranged in a horizontal direction and in a vertically spaced manner. The guide columns 41 are slidably connected in the guide grooves 14 so as to guide the scraper 40 to slide on the upper side of the filter screen 13.

[0056] The guide columns 41 are further rotatably connected with rollers 42 which can roll in the guide grooves 14 so as to reduce the frictional resistance when the scraper 40 slides.

[0057] The power mechanism 50 includes a power block 51, two fixed pulleys 52, a pull rope 53 and a reset elastic member 54. Specifically, the power block 51 is arranged in the drainage well 11 and is located directly below the filter screen 13. The power block 51 has a water storage groove 511 which is vertically upwardly arranged. The power block 51 is hingedly connected to the side wall of the drainage well 11 by a hinge shaft 55 so that the power block 51 can rotate downwardly or upwardly about the hinge shaft 55. The two fixed pulleys 52 are arranged on the two opposite side walls of the sewage channel 21 and are arranged at the connection between the sewage channel 21 and the drainage well 11. The lower end of the pull rope 53 is fixed to the side of the power block 51 away from the hinge shaft 55, and the upper end of the pull rope 53 is fixed to the scraper 40 after passing around the fixed pulleys 52. The reset elastic member 54 is a tension spring. The lower side of the road surface 10 is provided with a receiving groove 15 in which the reset elastic member 54 is arranged. One end of the reset elastic member 54 is fixedly connected to the scraper 40, and the other end is fixedly connected to the groove bottom of the receiving groove 15. The reset elastic member 54 causes the scraper 40 to have a tendency to move away from the sewage channel 21.

[0058] With the water in the water storage tank 511 continues to accumulate, when the power block 51 through the pull rope 53 exerted on the scraper 40 pull force is greater than the reset elastic member 54 exerted on the scraper 40 pull force, the power block 51 rotates downward around the hinge shaft 55, drive the scraper 40 to slide to the side close to the drain passage 21, push the accumulated debris such as leaves, plastic bags on the filter screen 13 into the drain passage 21, the reset elastic member 54 stretch. When the power block 51 is rotated downward around the hinge shaft 55 horizontally arranged to vertical arrangement, the scraper 40 moves to the connection between the drain passage 21 and the drainage well 11.

[0059] Referring to Figure 2 With Figure 4 , in order to make the power block 51 rotates downward around the hinge shaft 55, the water in the water storage tank 511 is not easy to pour out, the water storage tank 511 is provided with a floating plate 512, the floating plate 512 with the three inner side wall of the water storage tank 511 away from the hinge shaft 55 abuts and slides, the floating plate 512 and the inner side wall of the water storage tank 511 close to the hinge shaft 55 form a water permeable hole, so that the accumulated water can enter the water storage tank 511 through the water permeable hole.

[0060] Both sides of the floating plate 512 are fixed with guide columns 514, the axis of the guide column 514 and the axis of the hinge shaft 55 are parallel to each other. The two opposite inner side walls of the water storage tank 511 are provided with sliding grooves 515, the sliding grooves 515 are vertically arranged, the sliding grooves 515 do not penetrate the upper surface of the power, the guide column 514 slides in the sliding groove 515, to guide the floating plate 512 to float in the water storage tank 511.

[0061] Referring to Figure 4 With Figure 5 , in order to make the power block 51 rotates downward around the hinge shaft 55 horizontally arranged to vertical arrangement, the water in the power block 51 can be quickly discharged, the side of the power block 51 away from the hinge shaft 55 is provided with a water drain groove 516, the water drain groove 516 penetrates the upper surface of the power block 51, the water drain groove 516 and the water storage tank 511 are communicated with each other. The water drain groove 516 is provided with a cover plate 517, the cover plate 517 is slidably connected with the power block 51 along the opening direction of the water storage tank 511, to open and close the water drain groove 516. The side of the cover plate 517 facing the floating plate 512 is fixed with a driving block 518, so that the floating plate 512 slides outward along the opening direction of the water storage tank 511 can drive the cover plate 517 to open the water drain groove 516.

[0062] The municipal road drainage device also includes a cover plate drive mechanism 60, which corresponds one-to-one with the cover plate 517. When the floating plate 512 slides away from the opening of the water storage tank 511, the cover plate drive mechanism 60 drives the cover plate 517 to close the drainage tank 516. Specifically, the cover plate drive mechanism 60 includes a support plate 61, a sliding column 62, and an elastic element 63. The support plate 61 is arranged in a U-shape, with its opening facing the power block 51. The support plate 61 is fixed to the upper side of the power block 51 and located on the upper side of the drainage tank 516. The sliding column 62 is fixed to the upper side of the cover plate 517, passes through the support plate 61, and slides axially with the support plate 61 to guide the cover plate 517 to open and close the drainage tank 516. The elastic element 63 is a compression spring. The elastic element 63 is sleeved on the sliding column 62. The lower end of the elastic element 63 abuts against the upper side of the cover plate 517, and the upper end of the elastic element 63 abuts against the support plate 61. The elastic element 63 makes the cover plate 517 tend to cover the drain groove 516.

[0063] As the power block 51 rotates downward around the hinge axis 55, the floating plate 512, under the buoyancy of the accumulated water, continuously approaches the opening of the water storage tank 511. When the floating plate 512 moves to the opening of the water storage tank 511, it abuts against the drive block 518, causing the drive block 518 and the cover plate 517 to slide along the opening direction of the water storage tank 511, opening the drain trough 516. The elastic element 63 is compressed, and the accumulated water in the water storage tank 511 is discharged through the drain trough 516. As the accumulated water in the water storage tank 511 is discharged, when the tension applied to the scraper 40 by the power block 51 through the pull rope 53 is less than the tension applied to the scraper 40 by the reset elastic element 54, the reset elastic element 54 contracts, causing the scraper 40 to reset, and the power block 51 rotates upward around the hinge axis 55 to reset.

[0064] The implementation principle of Example 1 is as follows: The filter screen 13 filters the water entering the drainage well 11, causing debris such as leaves and plastic bags to remain on the upper side of the filter screen 13, making it less likely for the water to become clogged when draining through the drainage well 11. As water accumulates in the water storage tank 511, when the pulling force applied to the scraper 40 by the power block 51 through the pull rope 53 is greater than the pulling force applied to the scraper 40 by the reset elastic member 54, the power block 51 drives the scraper 40 to scrape the debris such as leaves and plastic bags on the upper side of the filter screen 13 into the sewage channel 21. The reset elastic member 54 is stretched. When the water flow in the drainage well 11 is large, some of the water passes through the sewage channel 21, transporting the debris such as leaves and plastic bags in the sewage channel 21 to the sunken green belt 30. When the floating plate 512 moves to the opening of the water storage tank 511, it drives the cover plate 517 to open the drain trough 516 to drain water, and the elastic member 63 is compressed. As the water in the water storage tank 511 is drained, when the pulling force applied to the scraper 40 by the power block 51 through the pull rope 53 is less than the pulling force applied to the scraper 40 by the reset elastic member 54, the reset elastic member 54 contracts to drive the scraper 40 to reset, the power block 51 rotates upward around the hinge shaft 55 to reset, the floating plate 512 falls back to the bottom of the water storage tank 511, and the elastic member 63 drives the cover plate 517 to cover the drain tank 516.

[0065] Example 2

[0066] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that sliders 5171 are fixed on both opposite side walls of the cover plate 517, and grooves 5161 are provided on both opposite side walls of the drain trough 516. The grooves 5161 are opened vertically and pass through the upper surface of the power block 51. The sliders 5171 slide in the grooves 5161 to guide the cover plate 517 to open and close the drain trough 516.

[0067] The difference between this embodiment and Embodiment 1 is that the cover plate driving mechanism 60 includes a hook 64 and a torsion spring 66. The hook 64 has a hook end 641 and a hinge end 642, with the hook end 641 located above the hinge end 642. A pivot block 5121 is fixed to the upper side of the floating plate 512, and a pivot shaft 65 passes through the pivot block 5121. The pivot shaft 65 is horizontally positioned and rotatably connected to the pivot block 5121 and the hinge end 642 of the hook 64, so as to hinge the hook 64 to the upper side of the floating plate 512. The torsion spring 66 is sleeved on the pivot shaft 65, and both ends of the torsion spring 66 are connected to the pivot block 5121 and the hook 64, respectively, so that the hook 64 tends to approach the cover plate 517.

[0068] The drive block 518 has two guide surfaces 519 on both the upper and lower sides. The two guide surfaces 519 are close to each other from the cover plate 517 to the hinge shaft 55. The guide surfaces 519 are used to guide the hook 64 to swing around the pivot shaft 65 in a direction away from the cover plate 517.

[0069] The principle of the embodiment of the example 2 is that when the floating plate 512 moves to the opening of the water storage tank 511, the hooking end 641 of the hook 64 first abuts against the driving block 518, the lower guide surface 519 guides the hook 64 to swing around the pivot shaft 65 away from the cover plate 517, then the hooking end 641 of the hook 64 goes up and passes the driving block 518, the floating plate 512 abuts against the driving block 518 to drive the cover plate 517 to open the water drainage tank 516 for water drainage, and the elastic member 63 is compressed. When the accumulated water in the water storage tank 511 is drained, the pulling force of the power block 51 applied to the squeegee 40 through the pull rope 53 is less than the pulling force of the reset elastic member 54 applied to the squeegee 40, the reset elastic member 54 is contracted to drive the squeegee 40 to reset, the power block 51 is rotated upward around the hinge shaft 55 to reset, the floating plate 512 falls back to the bottom of the water storage tank 511, the hooking end 641 of the hook 64 is hooked on the driving block 518 under the action of the torsion spring 66 to drive the cover plate 517 to cover the water drainage tank 516, after the cover plate 517 covers the water drainage tank 516, the floating plate 512 continues to fall back, the upper guide surface 519 guides the hook 64 to swing around the pivot shaft 65 away from the cover plate 517, and the hooking end 641 of the hook 64 passes the driving block 518 and continues to fall back with the floating plate 512.

[0070] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
