Abstract

The invention discloses a self-sealing gate which comprises a support, a bracket, a framework formed by a top plate, a sealing box, a gate, a cable and a waterproof jacket, wherein the gate comprises a guide rod for guiding and a door plate for water distribution; the door plate is articulated with an end part of the guide rod; a movable pulley is arranged at the other end of the guide rod; the top plate is provided with the cable; the cable is wound on the movable pulley and then penetrates through the waterproof jacket arranged at the top of the top plate; the waterproof sealing box surrounds the outer sides of the guider rod and pulley; a guide sleeve is arranged between the guide rod and the sealing box; a sealing ring is arranged on the inner side of the guide sleeve; the door plate is in a conical shape; and the bottom plate is provided with a conical hole matched with the door plate. Through the technical scheme, the self-sealing gate falls under the effect of the gravity thereof and water pressure when closed; the conical door plate is matched with the conical hole; and the self-sealing gate does not need a driving force, conforms to the fluid mechanics, has long service life due to little abrasion and a simple structure, and is convenient to overhaul.

Description

technical field [0001] The invention relates to water conservancy equipment, in particular to a self-sealing gate. Background technique [0002] With the construction of water conservancy and hydropower projects, water conservancy gates are indispensable equipment. The gates in the prior art are open-close gates, which need to be driven by power when opening and closing, and have a lot of wear and tear. After a period of use, due to the wear and tear of the gates, the gates will not close tightly, resulting in gaps and water overflow. When the gate is closed, the closing force is relatively large, and the requirements for each component of the gate are relatively high, resulting in huge equipment, complex structure, and difficulties in maintenance. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art and provide a self-sealing gate that does not require driving force when closed, ...
