Pipeline drainage structure

Abstract

A pipeline drainage structure comprises a baffle mechanism and a floating ball pulling mechanism, wherein the baffle mechanism consists of a fixed cover plate and a movable cover plate which are vertically overlapped together and provided with drain holes, and the drain holes on the fixed cover plate and the drain holes on the movable cover plate are staggered in position; one side of the movable cover plate is connected with a spring, and the other side of the movable cover plate is connected with the floating ball pulling mechanism; and the floating ball pulling mechanism consists of a floating ball, a traction rope and a fixed pulley, one end of the traction rope is connected with the floating ball, and the other end of the traction rope is connected with the movable cover plate by bypassing the fixed pulley. The pipeline drainage structure utilizes the buoyancy principle; the floating ball falls naturally in low water level under the gravity action, and the movable cover plate of the baffle mechanism is reset under the pulling action of the spring, and at the moment, the baffle mechanism is closed; and when the water level rises, the floating ball rises under the action of buoyancy to drive the movable cover plate to move, so that the drain holes on the fixed cover plate and the drain holes on the movable cover plate are gradually coincident together, and the baffle mechanism is opened.

Description

technical field [0001] The invention relates to the construction field, in particular to a pipeline drainage structure. Background technique [0002] In our life, we often find that the sewer pipes and rainwater pipes are easily blocked due to various debris. For this reason, sanitation workers need to dredge and clean them again and again. In thunderstorms, the water pipes are often difficult to keep up with the drainage demand due to the runoff. On the one hand, the caliber of the sewer cover itself is too small to meet the needs of the abnormal flow rate; on the other hand, it is also the main aspect, because the sewer pipe is usually blocked by sundries to cause its runoff flow. As a result, the sanitation workers had to open the inspection wells one by one to make the accumulated water on the road flow down. The downpipe and rainwater pipe of this structure have many inconveniences to use. Contents of the invention [0003] The object of the present invention is to ...
