Description

Sound Barrier {NOISE BARRIER}

The present invention relates to a sound barrier, and more particularly, to a sound barrier capable of generating green energy using a solar cell panel.

In general, a soundproof wall is installed in a structure that needs to reduce noise or noise caused by noise generated during driving of a vehicle or other various noises, or in a noise-damaged area to block noise generated. As an example of such a soundproof wall, after arranging a plurality of H-shaped posts on a foundation concrete at regular intervals, fixing the posts with anchor bolts, and absorbing or reflecting noise along the opposing panels of two adjacent posts. After sequentially stacking the soundproof panels in the transverse direction, respectively, there is a configuration in which the top is installed by fixing the connection plate.

However, it has been pointed out that additional utilization is necessary because these conventional soundproof walls require a lot of installation cost, but cannot be used for other functions other than soundproofing.

On the other hand, in recent years, along with carbon emission reduction policies, policies and technology development for green energy development have been actively carried out, and a representative example is a photovoltaic power generation device.

Such a photovoltaic power generation device is used to produce electrical energy using solar energy, and a representative example is a device that generates electricity by concentrating light on a solar cell, which is a solar panel.

However, to construct such a photovoltaic power generation device, a site with a good amount of sunlight irradiation must be selected, and civil engineering works such as grounding work to install solar cells on the selected site are required, resulting in a long installation period and high installation costs. There is a growing problem.

In addition, since a separate installation structure is required even when a solar power generation device is installed on the roof of a building, additional costs are incurred and maintenance is difficult.

Considering this point, the technology of installing and using solar cells on the above-mentioned soundproof wall has been attempted, but in installing solar cells between the pillars, it is difficult to install wires, junction boxes, sockets, etc. and to connect them. There is a problem that requires a long work time.

In addition, when the installed solar cell is damaged by an external impact such as a vehicle collision, the entire power generation function is lost due to damage to the wire and partial solar cell, and the wire and various parts exposed to the outside are easily degraded by being exposed to ultraviolet rays. There were problems with damage etc.

Korean Patent Publication No. 10-2016-0082013 (published on July 8, 2016) Korean Registered Patent No. 10-2115560 (registered on May 20, 2020)

The present invention has been devised to solve the above problems, and an object of the present invention is to provide a sound barrier having a structure that is easy to install and repair, and has a structure to sustain the power generation function even when a partial problem occurs.

The sound barrier of the present invention for achieving the above object includes a plurality of posts installed at regular intervals on the ground; A plurality of sound insulation plates for solar power generation coupled between the holdings and generating power through photovoltaic power generation and blocking noise; and a power transmission unit installed in the support and the ground, respectively, to connect the plurality of sound insulation boards for solar power generation in parallel to transmit power generated from the plurality of sound insulation boards for solar power generation.

Accordingly, it is possible to provide a sound barrier capable of simultaneously performing a noise blocking function as well as power generation using solar energy.

Here, the sound insulation board for solar power generation, a frame-shaped frame; a solar module supported and installed inside the frame; and a junction box electrically connected to the solar module and installed inside the frame.

Thus, it is possible to provide a sound insulation board that is easy to assemble and replace.

In addition, the solar module may include a pair of glasses having rims coupled to the frame; and a solar panel disposed between the pair of glasses, wherein the solar panel preferably includes a current collecting plate, and a first solar cell part and a second solar cell part installed on both sides of the current collecting plate, respectively.

As a result, since photovoltaic power generation can be performed using each of the two sides of the soundproof wall, power generation efficiency can be increased, and it can be installed regardless of the altitude or direction of the sun.

In addition, in each of the first and second solar cell units, a pair of half cells arranged in a width direction of the current collector plate at one side of one surface of the current collector plate and connected in parallel to each other are in series in a longitudinal direction of the current collector plate. a positive half cell portion disposed and electrically connected to each other by a bus bar; and a plurality of pair of half cells disposed in the width direction of the current collector plate and connected in parallel to each other on the other side of one surface of the current collector plate are arranged in series in the longitudinal direction of the current collector plate, and the negative electrode is electrically connected to each other by a bus bar. It is good to include; half cell portion.

Preferably, the positive half-cell part is connected to the positive electrode formed on the current collecting plate by the bus bar, and the negative half-cell part is connected to the negative electrode formed on the current collecting plate by the bus bar.

Thus, even if a solar cell in a specific part fails, stable functions can be secured by the parallel-arranged solar cell structure.

In addition, the junction box may include a front junction box built into the frame so as to be connected to the first solar cell unit; and a rear junction box built into the frame to correspond to the second solar cell unit.

Accordingly, it is possible to cope with the double-sided solar cell structure by integrating and installing the junction box inside the frame, thereby solving problems caused by external exposure and improving stability.

In addition, each of the front and rear junction boxes includes a junction box body installed inside the frame; a positive power transmission socket connected to the junction box body and exposed in a direction corresponding to the support; and a cathode transmission socket connected to the junction box body and exposed in a direction corresponding to the post.

Accordingly, the junction box can be easily assembled and connected when the sound insulation board is installed on the support.

In addition, the solar module may include a pair of glasses having rims coupled to the frame; a pair of solar panels disposed between the pair of glasses; and an absorption panel disposed between the pair of solar panels to absorb at least one of sound and vibration.

Thus, when the sound insulation board is installed on the support, it is possible to protect the solar panel by absorbing at least one of sound and vibration transmitted to the sound insulation board.

In addition, the power transmission unit, the holding line is installed on each of the holding, connecting a plurality of sound insulation boards for solar power generation installed in parallel to the holding line; An underground line installed in the ground where the holding line is installed and connected to the holding line; It is preferable to include; and a diode unit installed on a power transmission path so that each of the sound insulation boards for solar power generation independently performs a power generation function and transmits the generated power.

Thus, since it is possible to operate by connecting a plurality of soundproofing boards in parallel, even if some of them are damaged due to a vehicle collision, etc., the normally operable soundproofing board can be stably operated.

In addition, the holding line may include a holding line body installed inside the holding line; It is preferable to include; a plurality of anode and cathode power receiving sockets branched from the main line body and arranged to correspond to the respective sound insulation boards for solar power generation.

In addition, it is preferable that the sockets for receiving the anode and cathode are connected by an extension having a wire coil shape so that the length can be adjusted elastically from the body of the holding line.

As a result, it is possible to easily connect and install the sound insulation board to the support, thereby shortening the installation time so that even unskilled persons can easily construct the sound insulation board.

In addition, the diode unit includes first and second diodes for junction boxes installed in each of the junction boxes of the sound insulation board for solar power generation; and a third diode installed at each connection portion between the underground line and the holding line.

As a result, even if a part of the sound barrier is damaged due to a vehicle collision or the like, it is possible to maintain a stable function.

According to the sound barrier of the present invention, since the solar cells provided in each sound barrier, that is, the half cells are connected in parallel and in series, even if half cells are damaged due to an unexpected external impact, the half cells that do not have a problem can make it work normally.

In addition, since the soundproof wall is installed on the road without considering the azimuth or altitude of the sun, the phenomenon of shadows (heat island effect) caused by the corner panels of the soundproof wall greatly occurs, so the problem of not installing solar cells in the corner part However, according to an embodiment of the present invention, solar cells can be installed even on the edges, so if no shadows occur, power is generated as a whole, and power can be generated even if shadows occur, so the heat island effect can be solved. In particular, since the solar cell area per unit area increases, the amount of power generation can be increased.

In addition, since the power transmission unit is a structure connected using a triple diode structure, it can be operated to connect sound insulation boards in parallel. Therefore, it is possible to solve the problem that power generation is reduced even if the resistance due to the shadow heat island increases, and even if one sound barrier is broken or damaged, the other sound barrier can maintain its normal function.

In addition, the soundproofing board applied to the soundproofing wall of the present invention has a structure in which junction boxes and sockets are embedded inside the frame, and a holding line is pre-embedded and installed in the pillar, so that the installation and assembly work of the soundproofing board is easy and electrical It has the advantage of easy connection work by all persons.

In addition, by having a built-in configuration so that junction boxes and sockets are not exposed to the outside inside the frame of the soundproof board, durability is improved by being protected from the external environment (shock, UV dust, rainwater, snow, etc.), and product life It can be extended to reduce maintenance costs.

In addition, since the structure and external design of each soundproof board are simplified, packaging, storage and transportation are easy, assembly and installation work is facilitated, and visually superior products can be manufactured.

In addition, by modularizing the sockets for connection with the transmission line (holding line) and pre-embedding them in the holding posts and integrally embedding them in the junction box, the electrical connection work is facilitated.

In addition, by having a structure of a power transmission unit having a triple diode structure, it is possible to configure a single transmission line without the need to arrange a double transmission line due to the difference in power generation at each of the front and rear sides of the sound insulation board, thereby reducing costs Maintenance cost can be reduced.

In addition, since the on-site installation time of the sound barrier can be shortened, direct costs (installation costs, labor costs, maintenance costs, etc.) and indirect costs (social overhead costs such as road congestion and delays) can be reduced.

And since each sound insulation board and the solar cell of each sound insulation board are connected in a parallel structure, it is possible to maintain normal power generation in the remaining sound insulation boards without power generation during the operation of replacing some of the sound insulation boards.
