Cover plate blockage prevention structure for municipal drainage ditch

Abstract

The invention provides a cover plate blockage prevention structure for a municipal drainage ditch and discloses a blockage prevention structure capable of automatically cleaning a water drainage pointing joint of a cover plate under the driving of the impact of water flow in the ditch, capable of saving time and labor and capable of cleaning in time. The cover plate blockage prevention structure for the municipal drainage ditch is characterized in that two groups of fixing rods are correspondingly placed on the two sides of a water drainage cover plate; one group of fixing rods consists of twofixing rods; the two fixing rods in one group are correspondingly placed on the two sides of the water drainage cover plate; the two ends of a guide rod are connected with the two fixing rods in onegroup; multiple slide grooves which are distributed in an equally spaced manner are formed in the fixing rods; multiple connecting columns are arranged between the two fixing rods; the two ends of theconnecting columns are placed in the two opposite slide grooves in a slideable manner; the diameters of the two ends of a sliding column are less than the diameter of the middle part of the sliding column; multiple groups of through grooves which are distributed in an equally spaced manner are formed in the water drainage cover plate; the widths of the through grooves are gradually reduced from top to bottom; one group of through grooves consists of at least three through grooves; and the through grooves in one group are positioned right above the connecting columns.

Description

technical field [0001] The invention relates to an anti-clogging structure for a cover plate of a municipal drainage ditch, which relates to an anti-clogging structure capable of cleaning a drainage ditch cover plate, and belongs to the field of municipal engineering. In particular, it relates to an anti-clogging structure which is driven by the impact of the water flow in the groove and self-cleanes the drainage pointing of the cover plate, saves time and effort, and can be cleaned in a timely manner. Background technique [0002] In the municipal drainage system, in order to prevent the gutter from being blocked by solid debris, a cover plate with a drainage channel is usually added to the gutter for blocking, but after a period of use, the slot on the gutter cover plate It will be blocked by fine debris such as dust and fibers, which will hinder the drainage and flow capacity of the drain cover and affect the normal drainage effect.

[0002] In the municipal drainage system, in order to prevent the gutter from being blocked by solid debris, a cover plate with a drainage channel is usually added to the gutter for blocking, but after a period of use, the slot on the gutter cover plate It will be blocked by fine debris such as dust and fibers, which will hinder the drainage and flow capacity of the drain cover and affect the normal drainage effect. The existing cleaning methods are usually cleaned regularly by sanitation workers, and the cleaning speed is slow. The efficiency is low, the labor intensity is high, and the cleaning time is relatively delayed, which leads to the failure of the drainage system to drain normally

[0003] Notification number CN206667436U discloses a drainage ditch with a drainage ditch cover, including an injection-molded ditch body with a smooth inner wall and a drainage ditch cover. Components, the position corresponding to the fixed component on the drain cover is installed with an inverted "7"-shaped hook that opens outward, and the inverted "7"-shaped hook cooperates with the fixed component to fix the drain cover. The ditch body includes a three-surrounding structure formed by the ditch walls on both sides and the ditch bottom at the bottom. There are several integrated reinforcement plates distributed along the axis of the ditch body. The integrated reinforcement plates are fixed on the outside of the ditch wall and the lower side of the ditch bottom. One end of the inner wall of the ditch is provided with a card slot, the other end of the outer wall of the ditch is provided with an outer protrusion corresponding to the card slot, and the upper ends of the side walls on both sides of the ditch body are provided with a cover plate sinking platform. The pointing joints are easily blocked by debris, which affects the normal drainage and water flow, and requires manpower for regular cleaning

[0004] Notification No. CN208023696U discloses a novel double-open drainage ditch cover device. The main body, screws, and the soil layer are provided with a cement layer, and the upper surface of the cement layer is fitted with the bottom surface of the ground brick. The utility model is a new double-open drainage ditch cover device, and the structure is provided with a ditch cover. The left end surface of the outer fence of the left cover plate fits with the right end surface of the installation strip. The connecting port of the right cover plate and the connecting port of the left cover plate are on the same axis and are nested with connecting rods. The cover plate needs to be manually cleaned regularly Seams, more inconvenient
