Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit, in particular to a circular closed photovoltaic sound barrier for rail transit. BACKGROUND

[0002] With the acceleration of urbanization and the continuous expansion of rail transit network, subway, light rail, high-speed rail and other rail transit modes have become an important part of urban public transportation. However, rail transit, while bringing convenient transportation, has also caused increasingly serious noise pollution problems. The friction of wheels and rails, the operation of vehicle power systems and air dynamic effects during high-speed train running will produce high-intensity noise. In order to reduce the impact of rail transit noise on the environment and human beings, traditional sound barrier technology has been widely used.

[0003] However, the existing sound barrier technology mainly focuses on noise reduction function, and the function is relatively single, which cannot meet the needs of sustainable development of rail transit. Rail transit lines usually pass through urban areas, and there are rich light resources along the line. However, at present, these light resources are mostly not effectively utilized, causing great waste of energy. CONTENT OF THE INVENTION

[0004] In view of the defects of the prior art, the present application provides a circular closed photovoltaic sound barrier for rail transit, which has the advantages of effectively reducing rail transit noise, fully utilizing light resources along the line for photovoltaic power generation, not affecting the sound insulation performance of the sound barrier, and realizing efficient energy utilization, etc., solving the problems raised in the background art.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a circular closed photovoltaic sound barrier for rail transit, comprising a base, a bearing seat is fixedly installed on the upper surface of the base, a circular support frame is fixedly connected to the outer surface of the bearing seat, two groups of arc-shaped sound screen assemblies are arranged on the outer surface of the circular support frame, two symmetrical transparent sound insulation boards are fixedly installed on the outer surface of the circular support frame, and the two transparent sound insulation boards are located between the two groups of arc-shaped sound screen assemblies. Each of the mounting frames is fixedly connected with an acoustic cotton board inside, and each of the mounting frames is fixedly connected with an arc-shaped photovoltaic board on the outer surface. The arc-shaped photovoltaic board is located on the outer side of the acoustic cotton board. Two groups of guide rails are fixedly connected to the outer surface of the bearing seat, and two groups of silencers are arranged above the bearing seat.

[0006] Through the above scheme, through the cooperation between the arc-shaped sound screen assembly, the sound insulation board, the mounting frame and the sound-absorbing cotton board, the noise generated by the train running can be blocked and absorbed, and the high-frequency noise generated by the train running can be further absorbed by the muffler to reduce noise reflection, thereby providing a quieter living environment for residents along the line, and under the action of the arc-shaped photovoltaic board, the light resources along the rail transit can be used for photovoltaic power generation, realizing energy self-sufficiency, reducing the dependence on traditional energy, reducing carbon emissions, and integrating the arc-shaped photovoltaic board and the sound barrier structure, thereby improving the space utilization efficiency, having good economy and practicality.

[0007] Further, each mounting frame is fixedly connected with the circular support frame by bolts, and the curvature of the mounting frame is matched with the curvature of the circular support frame.

[0008] Through the above scheme, the mounting frame and the circular support frame are fixed by bolts, which can provide high pre-tightening force, and the curvature of the mounting frame and the circular support frame is matched, which can make them tightly combined, reduce gaps and clearances, improve the overall appearance of the sound barrier, and enhance the stability and sealing performance of the structure.

[0009] Further, the curvature of the arc-shaped photovoltaic board is matched with the curvature of the mounting frame, and the size of the arc-shaped photovoltaic board is matched with the size of the sound-absorbing cotton board.

[0010] Through the above scheme, the curvature of the arc-shaped photovoltaic board and the mounting frame is matched, which can make them better fit, so that external forces are evenly distributed to the entire contact surface, reducing the possibility of rupture of the arc-shaped photovoltaic board due to excessive local stress, and the matched curvature can make the appearance of the sound barrier more neat and smooth.

[0011] Further, the outer surfaces of the two groups of mufflers are fixedly connected to the outer surfaces of the mounting frames.

[0012] Through the above scheme, the muffler cooperates with the arc-shaped sound screen assembly to form a composite noise reduction structure, which significantly improves the comprehensive noise reduction performance of the sound barrier, more effectively reduces the noise level, and meets higher noise reduction requirements.

[0013] Further, the outer surface of the circular support frame is fixedly connected with a smoke exhaust duct.

[0014] Through the above scheme, the smoke exhaust duct can quickly exhaust high-temperature toxic smoke outside the station, avoid the accumulation of smoke in the closed space, create safe conditions for personnel evacuation and fire rescue, and improve safety.

[0015] Further, the inner side of the circular support frame is fixedly connected with equally spaced wrist-arm hangers.

[0016] Through the above scheme, the above setting of the cantilevered column can support the catenary structure, ensure that the contact line maintains stable tension and height, and provide reliable power supply for the train.

[0017] Further, the inner side surface of the circular support frame is fixedly connected with a first hanging bracket, and the inner side surface of the first hanging bracket is fixedly connected with equidistantly arranged positive feed lines.

[0018] Through the above scheme, through the action of the positive feed lines, the energy loss in the transmission process can be reduced, the overall efficiency of the power supply system can be improved, stable electric energy can be provided for the electric locomotive, and the energy utilization efficiency can be improved.

[0019] Further, the inner side surface of the circular support frame is fixedly connected with a second hanging bracket, and the inner side surface of the second hanging bracket is fixedly installed with a protection line.

[0020] Through the above scheme, the setting of the protection line can introduce lightning current into the ground, prevent lightning overvoltage from causing damage to the catenary equipment and the train, and the protection line can form an electrostatic shielding layer to reduce the influence of external electromagnetic interference on the catenary, thereby reducing the occurrence rate of catenary faults and improving the reliability of the power supply system.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] The circular closed photovoltaic sound barrier for rail transit can block and absorb noise generated by train operation through the cooperation between the arc-shaped sound screen assembly, the transparent sound insulation board, the mounting frame and the sound-absorbing cotton board, and further absorb high-frequency noise generated by train operation and reduce noise reflection by cooperating with the silencer, thereby providing a quieter living environment for residents along the line, and under the action of the arc-shaped photovoltaic board, photovoltaic power generation can be performed by utilizing the light resources along the rail transit, energy self-sufficiency is achieved, dependence on traditional energy is reduced, carbon emissions are reduced, and the arc-shaped photovoltaic board and the sound barrier structure are integrated, thereby improving space utilization efficiency, having good economy and practicality.
