Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040]A bottom-opening graded gate plate gate, comprising a gate base 10, a gate gate 20, a gate frame 3 at the gate gate, a gate plate matched with the gate frame, a screw rod 2 connected to the top of the gate plate to open and close the gate plate A hoist 1, a water stop rubber 7, and a wedge tight device 4 for adjusting the water stop effect; it is characterized in that:

[0041] The gate frame 3 is provided with two gate plates, and when the gate was closed, the gate plates went up and down, and when the gate was opened, the upper gate plate 5 descended earlier.

[0042] The gate frame 3 is arranged on the front of the gate, and the gate frame is provided with two water-stop rubber installation frames 18 and 13 at the gate position, and the water-stop rubber 7 is fixed around the inner wall of the installation frame and contacts the water-stop surface 24...

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...
