Abstract

The invention relates to a bottom pivot flap gate side water stop device and structure convenient to overhaul. The bottom pivot flap gate side water stop device convenient to overhaul comprises a chain with a bracket, a plurality of gears connected to and used for driving the chain, an inflatable water stop part fixed to the bracket of the chain, a transmission shaft connected with the gears, and a gear motor connected with the transmission shaft; the gear motor is arranged in a gate body; and one side face of the inflatable water stop part abuts against a gate side rail, and the other side face of the inflatable water stop part abuts against the side face of the gate body. According to the bottom pivot flap gate side water stop device and structure convenient to overhaul, the plane positions of the water stop part and the gears can be adjusted through the telescopic transmission shaft, deviation generated in the gate construction and installation period can be overcome, and water stopping can be better achieved.

Description

technical field [0001] The invention relates to a side water stop device and structure of a bottom pivot flap gate which is convenient for maintenance. Background technique [0002] With the development of the economy, the regulation of urban rivers has entered a peak period. In order to improve the urban water environment and beautify the city's appearance, the sluices built on urban inland rivers often use bottom-pivot flap gates. The bottom-pivot flap gate is usually closed, and the gate is controlled in different positions by the hydraulic hoist when adjusting the flow; when the flood is discharged, the bottom-pivot flap gate lies on the bottom of the water. This requires the bottom pivot flap gates of urban inland rivers to be opened and closed frequently. In the process of opening and closing, it is very easy to cause wear and tear on the side water stop, and the side water stop must be repaired and replaced every few years. [0003] At the same time, in order to achi...
