The present invention relates to a ship for a ship installation communication or broadcast system, in particular, in a ship for a communication or broadcast system for the purpose of installation in the ship's ship, the fixed state at the time of installation is improved to prevent the risk of falling, The hinge of the enclosure is configured to be detachable and relates to a ship for a ship-lined communication or broadcasting system that is easy to replace the failure portion and easy installation work.

In general, when installing an enclosure for an outdoor communication or broadcasting system, a large space for installation and maintenance is required as the installation space must be secured, and there are many difficulties for communication or broadcasting service providers due to frequent complaints caused by the installation work. . In order to economically compensate for this, a method for installing a communication or broadcasting system enclosure in Jeonju or Jeonju's barrage has been used.

On the other hand, electric poles are installed at intervals of 30 to 50 m at a height of 6 to 7 m from the ground, and a power line for power supply is installed at the upper part thereof. In addition, electric poles for the purpose of supporting cables for installation of optical cables or coaxial cables for communication or broadcasting systems by electric signals such as internet and cable broadcasting are installed in steel poles with a height of about 4 to 5 meters.

As such, the enclosure of the system installed for the purpose of communication and broadcasting on the overhead line should be safe and simple to install and maintain due to the difficulty in accessing the installation site, and also in harsh environments such as electromagnetic waves, high voltage current contact, dust, and bad weather. It must be designed to be suitable.

5A and 5B are a front view (a) of an open state and an enlarged cross-sectional view (b) of a clamp connection portion when installing a housing for a conventional communication or broadcasting system.

Conventional communication or broadcast system enclosure 40 is composed of a fixed part enclosure 400 is installed on the barbed wire 300, the enclosure cover 500 rotatable through the hinge portion 520, the clamp connection portion 430 It is installed on the barbed wire 300 by, and the input and output cable connectors (410, 412) are installed in the fixing unit enclosure (400).

The clamp connection part 330 is composed of a fixing screw 431 and a fixing block 432, positioning the tightening wire 300 between the fixing block 432 and the body 400 of the enclosure, tightening the fixing screw 431. As a result, a housing 40 for a communication or broadcasting system is installed in the barrage 300.

In the event of a failure of the housing 40 for a communication or broadcasting system, as a method for replacing a component, first, by loosening the fixing screw 515 of the housing cover 500 to open the housing cover 500 and then fixing the failure component. Disassemble the fixing screw 510 with a screwdriver and replace the defective part.

However, in the case of a conventional communication or broadcasting system enclosure, work should be performed at high altitude when installed on the overhead line. Therefore, a simple and safe operation should be avoided, but a separate safety device is required in the process of approaching the enclosure up to the overhead line. There is a high risk that the enclosure will fall.In addition, when the enclosure is installed, it can fall off between the clamp and the body in the process of tightening the clamping wire between the clamp and the body and tightening the set screw with a tool such as a spanner. This is large, in particular, there was a problem that takes a long time to install.

Furthermore, in case of a conventional case, in order to replace the corresponding parts when a failure occurs, if the assembly fixing screw is disassembled by using a tool such as a spanner, the housing cover is rotated 180 ° by the hinge part, and then the component fixing screw using a tool such as a screwdriver. The repair process is necessary to remove internal parts, replace internal parts, fix them, and then close the enclosure cover. This is not only very demanding, but also simplifies and simplifies work, as there is a risk of falling tools, parts, and even workers during operation. It is necessary to shorten.

In addition, conditions are required to be suitable for harsh environments such as electromagnetic waves, high-voltage current contact, dust and bad weather for good communication or broadcast services.

The present invention has been proposed in order to solve the above problems, in the case of a communication or broadcasting system for the purpose of installation on the joule of Jeonju, the operation is convenient when installed on the vessel, preventing the risk of falling, stable It is an object of the present invention to provide a ship for a ship-lined communication or broadcasting system that can secure and maintain a fixed state, a hinge part can be detached, and in the event of a failure, the repair and replacement of the trouble part is easy.

Another object of the present invention is to effectively cool internally generated heat, and to improve reliability by protecting internal components even in harsh environments such as electromagnetic wave exposure, high-voltage current contact and dust, bad weather, flooding, etc., which may occur frequently during installation conditions.
