Title:
PIPE CULVERT BLOCKAGE PREVENTING APPARATUS FOR ROAD ENGINEERING
Document Type and Number:
WIPO Patent Application WO/2024/061375
Kind Code:
A1
Abstract:
Disclosed in the present invention is a pipe culvert blockage preventing apparatus for road engineering, comprising a cylinder body, wherein a connecting ring is fixed at one end of the cylinder body. The apparatus can be directly mounted on existing built pipe culverts for use. When the apparatus is mounted at a water inlet fracture of a pipe culvert, an electric telescopic rod, a first electric telescopic rod, a motor and a first motor intermittently operate in sequence under the action of a PLC; when the electric telescopic rod, the first electric telescopic rod, the motor and the first motor operate in sequence, a plurality of L-shaped rods on a belt continuously hook debris pushed out of the side ends of inserting plates and transfer same towards cutting disks; the cutting disks rotate at a high speed under the action of the motor, such that when the debris is in contact with the plurality of cutting disks, the debris is divided into a plurality of sections; in this way, large-volume debris is cut into small sections, and the debris cut into the small sections can pass through the pipe culvert along with water flow to effectively achieve the objective of removing the debris at a water inlet port of the pipe culvert, thereby preventing the debris from blocking a water inlet end of the pipe culvert, and guaranteeing the smoothness of the water flow.
