Folding type noise elimination gate

Abstract

The invention belongs to the technical field of river dams, and discloses a folding type noise elimination gate. The folding type noise elimination gate comprises a steel gate plate, a folding door plate and a plurality of telescopic connecting rods. A first base is hinged to one end of the steel gate plate, and the first base is connected with the water bottom base surface. One end of the foldingdoor plate is hinged to a second base. The second base is connected with the water bottom base surface. The folding door plate is provided with a folding portion. One end of each telescopic connecting rod is connected with the water bottom base surface through a third base, and the other end of each telescopic connecting rod is hinged to the folding portion. The telescopic connecting rods are hinged to the third base. According to the folding type noise elimination gate, the flow relief opening degree of the gate can be adjusted through the telescopic connecting rods, and for the drainage when the gate is opened due to the full condition, a slope which is beneficial to the drainage can be formed, so that the noise of the water flow is reduced to the minimum, and the drainage noise of theurban river channel is eliminated.

Description

technical field [0001] The invention belongs to the technical field of river dams, in particular to a folding noise-reduction gate. Background technique [0002] Many cities in our country live near rivers. At present, urban ecological environment protection, water environment governance, and water landscape creation all require the realization of a multi-win situation for urban appearance, living environment, and green ecology. In the development of many urban areas, the requirements for water environment management are increasing day by day. Using urban rivers as landscape gates to raise water levels, "storing a reservoir of clear water and creating beautiful scenery on both sides" has gradually become the fashion of urban construction. At present, there are many types of urban landscape dams. From the perspective of materials, there are steel dams, rubber dams, composite material dams, etc.; from the perspective of structure, there are inflatable (water) dams, hydraulic d...

Problems solved by technology

[0003] First, the environmental noise generated by the discharge of the sluice gates is relatively high. Residents near the river complain more and more to the local government because they cannot get a good rest due to the excessive noise of the water flow; Good influence on test scores makes parents dissatisfied

[0004] The second is the serious atomization caused by the discharge of the gate, which greatly increases the humidity of the local environment near the river, which affects to a certain extent the wall decoration of buildings and houses, as well as household appliances such as residents' electrical facilities, furniture, bedding, etc.

[0005] The third is that there are certain defects in the structural design of the existing gates, and measures such as noise reduction and anti-fogging have not been seriously considered in the structural design, so that objectively, noise and fogging problems will occur in some small-scale flow and flow rate discharges.

For example, the landscape steel gate in a certain county in Sichuan is about 5.5 meters high. It enters the flood season every year. When the discharge reaches 1200 seconds cubic, the discharge will produce excessive noise, and the water will easily form fog after the water falls. not ideal
