Lower open-type grading gate-plate gate

Abstract

The invention relates to a gate technique which is a grading lower open-type restrictor gate. The lower open-type restrictor gate comprises a brake base, a gate frame at an outlet of the gate, restrictors that are matched with the gate frame, a hoist above the restrictor, a water-stop rubber and a locking apparatus which is used for controlling the efficiency of water sealing. The gate is characterized in that the upper restrictor which descends primarily when the gate is opened and the lower restrictor are arranged in the gate frame; two mounting frames of the water-stop rubber are arranged in the gate frame which faces to the outlet of the gate, wherein, the water-stop rubber is fixed on the four borders of the mounting frame which is contacted with a water-stop surface of the inner wall of the restrictor. A locating pull plate which extrudes from the surface of the restrictor is arranged at the both sides of the upper end of the lower restrictor, wherein, the inner side of the locating pull plate is provided with an upper wheel and the edge of the upper wheel is contacted with the upper restrictor, meanwhile the both sides of the lower end of the lower restrictor are provided with a lower wheel that extends to one side of the upper restrictor. The grading restrictor has reasonable structure, good water-stop efficiency, space conservation due to the grading restrictor, labor and material conservation in construction, light weight of stainless steel which is used as raw material, convenient installation and transportation.

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.
