Description

Technical Field

[0001] The present application relates to the technical field of trash-blocking devices, and more specifically, to a trash-blocking device for bridges and culverts. Background Art

[0002] With the rapid development of urban life, urban garbage and waste are randomly discarded in the river water, which will seriously pollute the water quality and have a serious impact on the water conservancy facilities along the river. In order to prevent garbage and waste from drifting with the river, affecting more far-reaching waters, and reducing damage to the water ecosystem, it is necessary to add pollution interception equipment in the river. In order to facilitate the cleaning and collection of garbage and waste, it is usually chosen to set up pollution interception equipment at the bridge culvert of the bridge, which can then be convenient for installation and maintenance of the pollution interception equipment. The existing public technology number CN213836595U proposes a pollution interception device for water conservancy bridges and culverts. The device has a simple structure and a reasonable design. It can intercept pollution from bridges and culverts, and at the same time it can centrally process garbage to avoid blockage in rivers. In view of the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: when the pollution intercepting device in the comparative literature is used, if the water level changes, the intercepting net needs to be adjusted regularly, otherwise the intercepting capacity of the intercepting net will gradually decrease when the water level decreases. In addition, the intercepting net is arranged in a flat surface, and the lifting mechanism drives the collection trough to rise, which may easily cause some garbage to not be collected, and it is necessary to collect it repeatedly, and the collection efficiency is not high. In addition, the intercepting net is below the water surface, and the later maintenance is relatively inconvenient. In view of this, we propose a pollution intercepting device for bridges and culverts. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] The purpose of the present application is to provide a pollution intercepting device for bridges and culverts, which solves the problem that when the pollution intercepting device in the comparative literature in the above-mentioned background technology is used, if there is a change in the water level, the intercepting net needs to be adjusted regularly, otherwise when the water level decreases, the intercepting ability of the intercepting net gradually decreases. In addition, the intercepting net is arranged in a plane, and the lifting mechanism drives the collection trough to rise, which easily causes some garbage to not be collected, and it is necessary to collect repeatedly, the collection efficiency is not high, and the intercepting net is located below the water surface, and the technical problem of inconvenient later maintenance is realized. A floating body mechanism composed of two floating barrels and an F-shaped guide rail fixedly connected is installed on both sides of the bridge and culvert respectively. Under the action of the floating barrel and the F-shaped guide rail, one end of the intercepting net is always above the water surface, and a J-shaped net structure is formed, so as to achieve a good pollution intercepting effect. Moreover, because the floating barrel floats on the water surface, the pollution intercepting ability will not be reduced. The two pull ropes are synchronously pulled by the traction equipment, so that the end of the intercepting net below the water surface is slowly moved up to the water surface, so that the garbage is concentrated on the water surface, which is convenient for centralized cleaning of the garbage, and the intercepting net can also be convenient for maintenance and cleaning.
