Description

Technical Field

[0001] The utility model relates to the field of sound barriers for substation projects, and more specifically, it is a movable noise reduction barrier for substation projects that can be inspected externally. Background Art

[0002] There are many noise sources in the equipment of high-voltage substations and converter stations. With the implementation of relevant laws, substation projects (such as substations, converter stations, etc.) generally need to take certain noise reduction measures. Among them, setting up a sound barrier between the sound source equipment and the protected object is one of the most common noise reduction measures.

[0003] To meet these requirements, the current mainstream approach is to use a steel frame fixed to a reinforced concrete foundation, coupled with metal sound-absorbing panels, as a sound barrier. However, the construction of reinforced concrete foundations or walls is time-consuming, requiring significant on-site input of raw materials, machinery, and labor, resulting in significant construction waste and severe on-site noise, smoke, and dust pollution. Furthermore, sound barriers near equipment, fixed to a reinforced concrete foundation, can hinder equipment replacement and transport. Furthermore, the metal sound-absorbing panels can obstruct vision, creating inconvenience for operators and maintenance personnel.

[0004] In summary, the existing sound barrier structure has the disadvantages of long construction period, waste of resources, serious pollution, and inconvenient replacement and transportation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned background technology and to provide a mobile noise reduction barrier that can be used for external inspection of substation projects, which can solve the technical problems of long construction period, waste of resources, serious pollution, and inconvenient replacement and transportation.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a mobile noise reduction barrier that can be externally inspected in a substation project, comprising a plurality of steel columns, a steel bottom beam located at the lower section of the steel columns, and a steel top beam located at the upper section of the steel columns. The plurality of steel columns, the steel bottom beam and the steel top beam form a sound barrier frame, and sound barrier panels are provided between adjacent steel columns. The sound barrier frame and the sound barrier panels form a noise reduction barrier.

[0007] As a preferred solution, the sound barrier panel includes a transparent sound barrier panel and a metal sound absorbing and insulating panel, wherein the transparent sound barrier panel is located in the lower section and the metal sound absorbing and insulating panel is located in the upper section.

[0008] Furthermore, the sound barrier panels are inserted into the slots of adjacent steel columns and compressed by angle steels, and the angle steels are fixed to the steel columns by fixing bolts for compressing the angle steels.

[0009] Furthermore, a steel column bottom plate is provided at the bottom of the steel column in the transverse direction, and a pulley is provided at the bottom of the steel column bottom plate.

[0010] Furthermore, the lower section of the steel column is provided with a steel column bottom connecting steel plate, which extends toward the steel bottom beam and is fixedly connected to the steel bottom beam via steel bottom beam fixing bolts.

[0011] Furthermore, vertical stiffening ribs and horizontal stiffening ribs are provided inside the lower section of the steel column. The vertical stiffening ribs are arranged parallel to the bottom plate of the steel column in the vertical direction, and the horizontal stiffening ribs are arranged on both sides of the steel column in the horizontal direction.

[0012] As a preferred solution, the steel top beam is fixed to the upper section of the steel column by steel top beam fixing bolts.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1) The utility model shortens the construction period of the sound barriers of transformer substations and converter stations.

[0015] 2) The utility model reduces the input of on-site materials, machinery and personnel, reduces the discharge of construction waste, reduces noise pollution and reduces carbon emissions.

[0016] 3) The utility model is convenient for daily inspections by operating personnel. When equipment needs to be moved during maintenance, it can be moved quickly to make way for equipment transportation, effectively saving power outage time and improving work efficiency.
