Intelligent sound insulation barrier for high-speed train

Abstract

The invention discloses an intelligent sound insulation barrier for a high-speed train. The intelligent sound insulation barrier comprises a high-speed rail elevated frame; rails are arranged in the high-speed rail elevated frame. A fixed plate is fixedly arranged on a bottom surface of the high-speed rail elevated frame; a triggering mechanism for detecting the vibration amplitude of the rails and triggering the sound insulation barrier to insulate sound is arranged between the rails and the fixed plate; according to the device, when a train does not pass, photovoltaic power generation panelsare used for generating power; the generated electric energy can be subsequently supplied to a sound wave counteracting mechanism, and green and environment-friendly effect are realized; besides, thedevice is automatically stored when not insulating sound, is long in service life, and can automatic unfold when insulating sound; the intelligent sound insulation barrier is sensitive in response and high in automation degree, meanwhile, when insulating sound, the device utilizes the vibration air of a sound wave plate to counteract noise generated by the running train; the device has an activenoise elimination function, the noise is prevented from being reflected to the train through a sound insulating plate, and a noise blocking effect is good.

Description

technical field [0001] The invention relates to the field of traffic noise reduction, in particular to an intelligent noise barrier for high-speed trains. Background technique [0002] As we all know, with the development of transportation, the speed of high-speed trains is getting faster and faster. At the same time, the noise generated by high-speed trains is getting stronger and stronger. Some high-speed railway elevateds will inevitably pass through residential areas during planning and laying. Noise will seriously affect the living environment of residents in residential areas. Therefore, noise barriers must be installed on this section of the high-speed rail elevated; while traditional noise barriers are simply fixed on both sides of the high-speed rail elevated, in harsh environments, such as storms, It is prone to damage, and rainwater will also erode the noise barriers fixed on both sides of the high-speed railway elevated. The traditional noise barriers have a shor...

[0002] As we all know, with the development of transportation, the speed of high-speed trains is getting faster and faster. At the same time, the noise generated by high-speed trains is getting stronger and stronger. Some high-speed railway elevateds will inevitably pass through residential areas during planning and laying. Noise will seriously affect the living environment of residents in residential areas. Therefore, noise barriers must be installed on this section of the high-speed rail elevated; while traditional noise barriers are simply fixed on both sides of the high-speed rail elevated, in harsh environments, such as storms, It is prone to damage, and rainwater will also erode the noise barriers fixed on both sides of the high-speed railway elevated. The traditional noise barriers have a short service life; in addition, the traditional noise barriers have a single function and can only passively block the noise generated by the train. The noise will be reflected twice through the sound insulation barrier. Since the essence of the noise is air vibration, the reflected noise may bounce back to the surface of the high-speed train, which may produce a series of unexpected effects. For example, passengers in the car by the window may be affected by instantaneous High-frequency noise; therefore, it is necessary to design an intelligent noise barrier for high-speed trains to solve the above problems
