Problems solved by technology
[0006] 1) It usually takes 2-3 days to remove the fixed noise barrier, and another 2-3 days to install it again
[0007] 2) The fixed sound barrier body is easily damaged during disassembly and assembly (maybe up to 20%-30%), resulting in a lot of waste
The disassembled screen needs a separate storage space
[0008] 3) The disassembly and assembly of the fixed sound barrier requires the use of large mechanical equipment and a large operating space

The invention discloses a moving type sound-insulation barrier which comprises a sound-insulation barrier board assembly. The sound-insulation barrier board assembly comprises at least two sound-insulation barrier boards which are opposite and vertically arranged. Each sound-insulation barrier board is formed by sequentially stacking a face protection hole board, alkali-free hydrophobic glass cloth, glass wool and a back board, and S-shaped sound absorption and insulation boards are arranged between the sound-insulation barrier boards at intervals from top to bottom. The vertically-adjacent sound absorption and insulation boards are arranged in a staggered mode, and air channels are formed. The moving type sound-insulation barrier further comprises a steel-structure frame and a base. The steel-structure frame comprises a base plate and a fixing part connected to the middle of the base plate, the sound-insulation barrier board assembly is connected with the fixing part, a universal wheel is arranged at the bottom of the base plate, and the universal wheel rolls on the base. The moving type sound-insulation barrier can ensure that the moving type sound-insulation barrier can be used in a hostile environment for a long time, and damage to the moving type sound-insulation barrier due to the problems of corrosion, abrasion and the like is avoided.
Description
technical field [0001] The invention relates to a sound insulation barrier, in particular to a mobile sound insulation barrier for substation sound insulation. Background technique [0002] Substation is an important power production place. With the development of modern cities and industrial and agricultural economies, some substations will be located in the center of the city or densely populated areas. Therefore, the noise generated during the operation of various electrical equipment in the substation will inevitably have an impact on the staff in the substation, nearby residents and the environment. Today, with increasing emphasis on environmental protection, it is becoming more and more important to control the noise in the substation and reduce the impact on the staff and the environment. [0003] Commonly used substation noise control methods mainly include noise reduction measures for the equipment body, noise reduction optimization measures for substation layout,...
