Description

Technical Field

[0001] The utility model relates to the technical field of road drainage, in particular to a municipal road drainage device. Background Art

[0002] Road drainage refers to a series of measures taken during the construction and maintenance of roads, aimed at effectively managing and controlling rainwater, snowmelt water and other water sources discharged from the road surface, preventing waterlogging and road damage, and ensuring safe passage of roads. At present, the common drainage facilities on municipal roads are to set up drainage ditches on both sides of the road and drain water through pipes at the bottom of the drainage ditch. However, since the drainage ditch is set on the road surface, when it rains and drains, leaves and other impurities on the road surface will pass through the grille at the top of the drainage ditch into the drainage ditch. These leaves and impurities will cause the bottom of the drainage pipe to be blocked, affecting the normal drainage. In order to prevent the drainage pipe from being blocked, a filter screen will be set at the bottom of the drainage ditch, but the filter screen is stationary. As the drainage proceeds, the impurities on the filter screen will increase, causing the filter screen to be blocked, affecting the normal drainage of the drainage ditch. Utility Model Content

[0004] The anti-blocking mechanism includes an impeller, a rotating rod, a filter, a scraper and a support ring. The side surface of the support ring is fixedly connected to the inner side surface of the lower end of the drainage bucket. The support ring is provided with a filter. The top of the filter is rotatably connected to one end of the rotating rod. The side surface of the middle part of the rotating rod is fixedly connected to the inner side surface of the impeller. Two scrapers are fixedly installed on the side surface of the lower end of the rotating rod. The two scrapers are in contact with the top of the filter. A positioning groove matching the rotating rod is provided in the middle part of the bottom of the fixed plate. A water collecting bucket is fixedly installed at the bottom of the support ring. A drain pipe is fixedly installed at the bottom of the water collecting bucket. The lower end of the water collecting bucket is connected to the interior of the drain pipe.

[0005] As a preferred technical solution of the utility model, a handle is rotatably installed in the groove on the top of the fixed plate, and the handle is U-shaped.

[0006] As a preferred technical solution of the utility model, a plurality of positioning pins are fixedly installed on the bottom of the bearing ring, and a positioning hole matching with the positioning pins is opened on the top of the drainage bucket.

[0007] As a preferred technical solution of the utility model, steel balls are rotatably installed in the grooves of the inner wall of the positioning groove, and the number of the steel balls is not less than four.

[0008] As a preferred technical solution of the utility model, a reinforcing rib is fixedly installed on the bottom of the filter screen, and the reinforcing rib is arranged in a cross shape.

[0009] As a preferred technical solution of the utility model, a rubber ring is fixedly installed on the top of the support ring, and the rubber ring cooperates with the filter screen.

[0010] The beneficial effects of the utility model are as follows: the utility model can perform preliminary filtering of leaves and impurities on the road surface through the grille, and can perform secondary filtering of water through the filter screen at the bottom of the drainage bucket to prevent impurities from entering the drainage pipe, and when rainwater flows into the drainage bucket from the top, the water flow will drive the impeller to rotate, so that the impeller drives the rotating rod and the scraper to rotate, so that the scraper can scrape up the impurities gathered on the filter screen to prevent the impurities from clogging the filter screen, so that drainage can proceed smoothly. The filter screen and the impeller are designed as separate parts from the drainage bucket, which can be easily taken out for cleaning and maintenance. People can easily lift the grille and the bearing ring by hand to facilitate cleaning of the inside of the drain bucket. The grille can be positioned by the positioning pins and positioning holes to prevent displacement when people walk or vehicles run over it. The steel balls can reduce the friction between the rotating rod and the positioning groove so that the impeller can rotate more smoothly under the impact of the water flow. The reinforcing ribs can increase the supporting force and strength of the filter to prevent deformation of the filter. The rubber ring can improve the sealing between the filter and the supporting ring to prevent fine impurities such as mud and sand from entering the drain pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The anti-blocking mechanism 5 includes an impeller 51, a rotating rod 52, a filter screen 53, a scraper 54 and a support ring 55. The side of the support ring 55 is fixedly connected to the inner side of the lower end of the drain bucket 1. The filter screen 53 is placed on the support ring 55. The top of the support ring 55 is fixedly installed with a rubber ring 14. The rubber ring 10 cooperates with the filter screen 53. The rubber ring 10 can improve the sealing between the filter screen 53 and the support ring 55 to prevent fine impurities such as mud and sand from entering the drain pipe 8. The top of the filter screen 53 is connected to the rotating rod 52. One end of the rod 52 is rotatably connected, and a reinforcing rib 13 is fixedly installed at the bottom of the filter 53. The reinforcing rib 13 is arranged in a cross-shaped shape. The reinforcing rib 13 can improve the support force and strength of the filter 53 to prevent the filter 53 from being deformed. The side of the middle part of the rotating rod 52 is fixedly connected to the inner side of the impeller 51. Two scrapers 54 are fixedly installed on the side of the lower end of the rotating rod 52. The two scrapers 54 are in contact with the top of the filter 53. The middle part of the bottom of the fixed plate 4 is provided with a The positioning groove 6 has steel balls 12 rotatably installed in the groove on the inner wall of the positioning groove 6. The number of steel balls 12 is not less than four. The friction between the rotating rod 52 and the positioning groove 6 can be reduced by the steel balls 12, so that the impeller 51 can rotate more smoothly under the impact of the water flow. A water collecting bucket 7 is fixedly installed at the bottom of the support ring 55, and a drainage pipe 8 is fixedly installed at the bottom of the water collecting bucket 7.
