Lower open-type grading gate-plate gate

Abstract

The invention relates to a gate technology, which is a bottom-opening graded gate plate gate. The bottom-opening graded gate plate gate includes the gate base, the gate frame at the gate door, the gate plate matched with the gate frame, the hoist above the gate plate, the water-stop rubber, and the wedging device for adjusting the water-stop effect; its characteristics Yes: There are upper and lower gate plates in the gate frame, and when the gate is opened, the upper gate plate descends first. The gate frame is provided with two water-stop rubber installation frames on the front of the gate door, and the water-stop rubber is fixed on the four sides where the water-stop surface of the gate plate on the inner wall of the installation frame contacts. On both sides of the upper end of the lower gate plate, there are positioning pull plates protruding from the plane of the gate plate. On the inner side, there is an upper pulley. The edge of the upper pulley is in contact with the upper gate plate. Lower the pulley. Due to the graded gate plate, the structure is reasonable, the water-stop effect is good, the graded gate plate saves space, and saves labor and materials during construction. Made of stainless steel, light in weight, easy to install and transport.

Description

technical field [0001] The invention relates to a gate technology, which is an improvement on the gate. Specifically, when the gate is opened, the gate plate opens downwards and contains a graded gate plate. Background technique [0002] In cities and towns, gates are provided in the interception wells that handle domestic waste water and rainwater, and that rainwater and sewage are more thoroughly diverted, in the sewage pools of sewage treatment plants, and in the purification pools of waterworks. Generally, when the gate used at present is used, the gate plate vertically slides upwards when opening, and the gate plate slides downwards when closing. There are some defects like this, at first, cause the overall space height of the gate well to increase. For example, for a gate with a diameter of one meter, it is necessary to reserve at least 1.5 meters of space above the opening for the gate plate to slide during civil construction. It is impossible for the bottom of the...

Problems solved by technology

[0006] In addition, in today's gates, the water-stop rubber is placed on the gate plate, which not only makes the water-stop rubber wear faster, but also has a poor water-stop effect.
