Sound insulation and noise reduction type bottom transverse shaft flap steel gate dam

Abstract

The invention discloses a sound insulation and noise reduction type bottom transverse shaft flap steel gate dam. The gate dam comprises a base and two symmetrical hoist chambers, wherein the bottoms of the hoist chambers are fixedly installed at the top of the base, a bottom transverse shaft is movably connected between the inner walls, close to each other, of the two hoist chambers, a gate plateis fixedly installed on the outer surface of the top of the bottom transverse shaft, uniformly distributed supporting hinges are arranged between the top surface of the base and the outer surface of the bottom transverse shaft, uniformly distributed shaft sleeves are movably connected to the outer surface of the bottom transverse shaft, horizontal gaskets are arranged between the bottoms of the shaft sleeves and the top surface of the base, and the bottoms of the horizontal gaskets are fixedly connected with the top surface of the base through bolts. According to the gate dam, a sound insulation box body can provide sound insulation and noise reduction effects for the hoist chambers, in addition, a driving motor can be damped through arranged shock pads, springs and other structures, and therefore noise generated by vibration when the driving motor works is reduced.

Description

technical field [0001] The invention belongs to the field of steel gate dams, and relates to sound insulation and noise reduction technology, in particular to a sound insulation and noise reduction type steel gate dam with a bottom horizontal axis flap. Background technique [0002] The bottom shaft driven flap gate is a new type of gate that can realize two-way water retaining, flexible opening and closing, stepless adjustment of gate opening, convenient scheduling, engineering concealment, no hindrance to flood control and navigation, and improved river landscape. The research results are A major breakthrough in the design of long-span gates, the synchronous control of two independent hydraulic systems for bottom shaft drive gates, the support and connection of ultra-long and heavy-duty drive shafts, manufacturing and installation processes, long-term anti-corrosion of underwater metal structure equipment, Key technologies such as bearing materials and bearing structures u...

Problems solved by technology

[0005] The purpose of the present invention is to provide a sound-insulating and noise-reducing bottom horizontal-axis flap steel gate dam, which is used to solve the problem that a large amount of noise will be generated when the traditional steel gate dam is in use. At the same time, a blower is provided to ventilate the hoist room of the steel gate dam Heat dissipation, and can reduce the humidity of the internal environment of the hoist, so that the motor components can work in a low temperature and dry environment. In addition, the PLC control module set can intelligently and automatically control the opening and closing of the blower and the electric push rod , when the water level is too high, the precipitation is too large, the difference between the indoor and outdoor humidity of the hoist is too large, and the noise decibel is too large, the blower will be automatically turned off, and the air inlet and outlet pipes will be sealed to avoid moisture outside the equipment Enter the interior of the hoist;
