L-shaped concrete prefabricated part for river channel

Abstract

The invention relates to the field of concrete prefabricated parts, in particular to an L-shaped concrete prefabricated part for a river channel, which comprises a first prefabricated part and a second prefabricated part, a collecting box is arranged between the first prefabricated part and the second prefabricated part, rotating frames are slidably mounted on the left side and the right side of the collecting box respectively, and a first rotating shaft is mounted in the collecting box between the rotating frames; the first rotating shaft is fixedly installed at the circle center position of the rotating frame, guide plates are slidably installed on the other side of the rotating frame, guide grooves are formed in the sides, close to the collecting box, of the guide plates, four cleaning frames are symmetrically arranged on the outer side of the collecting box, and guide rods move up and down so that scraping plates can move up and down to clean the cleaning frames; meanwhile, intermittent flow blocking and releasing of water flow are achieved, the ecological environment can be enhanced, a hook rod can stretch out and draw back in the cleaning frame, a limiting block can stretch out and draw back through rotation of a second rotating shaft, and disassembly and assembly between the whole device and the concrete prefabricated part are facilitated.

Description

technical field [0001] The invention relates to the field of concrete prefabricated parts, in particular to an L-shaped concrete prefabricated part for a river course. Background technique [0002] Prefabricated parts, also known as PC components, refer to concrete products processed and produced in factories through standardized and mechanized methods. Correspondingly, traditional cast-in-place concrete requires on-site mold making, on-site pouring and on-site maintenance. Concrete prefabricated parts are widely used in construction, transportation, water conservancy and other fields, and play an important role in the national economy. [0003] When constructing embankments on both sides of the river, concrete prefabricated parts are required to prevent the sides of the river from being washed by the water flow, causing soil loss on both sides.

[0003] When constructing embankments on both sides of the river, prefabricated concrete parts are required to prevent the sides of the river from being scoured by water flow, causing soil loss on both sides of the river. During the construction of river embankments, due to the spread of domestic garbage, there will be some garbage in the river. These garbage If it is not cleaned up, it will be eaten by some aquatic animals and cause harm to the lives of these animals. However, general concrete prefabricated parts do not have the ability to clean up garbage. Garbage accumulation will adhere to the surface of concrete prefabricated parts. Concrete prefabricated parts and accumulated garbage solidify as a whole, and the rotten garbage will cause corrosion to the concrete prefabricated parts, damage the structure of the concrete prefabricated parts, cause the concrete prefabricated parts to become brittle, reduce the service life, and cause a large number of bacteria to grow. It will cause adverse effects on water quality and worsen the living environment of aquatic animals, and if it is cleaned manually, it will greatly increase labor costs, and the cleaning efficiency is low. Therefore, in summary, it is necessary to design related equipment
