Automatic unloading type closed sound barrier

Abstract

The invention discloses an automatic unloading type closed sound barrier. The automatic unloading type closed sound barrier comprises H-shaped steel stand columns, an H-shaped steel beam plate, a wire harness, a wind speed sensor, a solar cell transparent plate and an automatic unloading type unit plate; the H-shaped steel stand columns support each other to form a frame structure; the H-shaped steel beam plate is installed on the upper portion of the frame structure; the solar cell transparent plate is arranged at the top of the H-shaped steel stand column located on the upper portion; the wind speed sensor is arranged at the top of the solar cell transparent plate; the automatic unloading type unit plate is arranged at the end, located at the bottom, of the H-shaped steel stand column; and a control box and a storage battery are electrically connected with the automatic unloading type unit plate. A sound absorption and insulation unit plate of the sound barrier with the above structure is detachable, rotating power is provided by a direct current motor, electric energy of the direct current motor is provided by the solar cell transparent plate at the top of the closed sound barrier, thus, the load of the sound barrier is increased, and used energy is clean energy, and the sound barrier is environmentally friendly and efficient.

Description

technical field [0001] The invention belongs to the technical field of closed sound barriers, in particular to an automatic unloading closed sound barrier. Background technique [0002] The sound barrier refers to a facility inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the impact of noise in a certain area where the receiver is located. In the process of sound wave propagation, when it encounters a sound barrier, three phenomena will occur: reflection, transmission and diffraction. Usually we think that the barrier can prevent the propagation of direct sound and attenuate the directed sound enough, while the influence of transmitted sound can be ignored. Therefore, the sound insulation effect of the sound barrier can generally be expressed by the amount of noise reduction, which reflects the above two abilities of the sound barrier to shield sound transmission. A sound barr...

AI Technical Summary

Problems solved by technology

The external force transmitted by the sound barrier through the embedded parts needs to be considered in the foundation design, which also requires high structural design of the bridge beam, which invisibly increases the cost

And when the sound barrier noise reduction treatment is carried out for the existing bridge, because the existing bridge cannot bear the load of the fully enclosed sound barrier
