Description

[Detailed Description of the Invention] The present invention relates to a weather-resistant communication equipment storage box that accommodates a communication device, a control device, a parabolic antenna, etc.

Conventionally, communication equipment storage boxes have often been square, and have structures with walls such as glass wool insulation walls, foamed urethane insulation walls, paper honeycomb structure insulation walls, etc. to reduce the effects of solar heat, and the communication equipment body and parabolic antenna are connected to each other. were equipped separately.

FIG. 1 is an external view in which a communication equipment housing box and a parabolic antenna are separately installed.

1 is a parabolic antenna, 2 is a steel tower on which the parabolic antenna is fixed, 3 is a rectangular communication equipment housing box, and 4 is a cable or waveguide that connects the parabolic antenna and the main body of the communication device.

FIG. 2 is a front view of the rectangular communication equipment housing box 3 shown in FIG.
It is a half sectional view at the center.

This structure consisted of the following parts:

That is, a square outer casing 5, a heat insulating material 6 made of glass wool, foamed urethane, paper honeycomb, etc. stretched inside the outer casing 5 to block solar radiant heat and retain heat within the surface, a ventilator 7, and a dust-proof bottom air filter. It is a rectangular housing box consisting of an intake port 8, a ceiling ventilation fan 9, and an entrance/exit door 10, and a communication device main body 20 is housed inside the box.

This structure has the problem that the connection between the parabolic antenna and the main body of the communication device becomes long, resulting in increased signal transmission loss therebetween.

In order to improve the quality of this communication equipment, it has become necessary to have a housing case with an integrated structure in which the communication equipment main body and the parabolic antenna are brought closer to each other.

Various types of housing boxes that integrate an antenna and a communication device main body have been considered.

However, the problem with this integration is that the whole unit becomes large and transport is restricted.

Secondly, the large size increases the area of the wind blowing area, and the outer shell needs to be streamlined to reduce wind pressure.

This streamlined shape makes it difficult to provide heat insulating walls, making it more susceptible to the effects of solar heat.

Furthermore, if the device is separated for transportation, it will be necessary to ensure that the location where the device is installed is waterproof.

In order to solve these problems, the present invention has developed a double wall in which the outer periphery of a cylindrical storage box is divided and surrounded by an outer shell made up of several panels with curved surfaces that can be assembled at any location. The purpose is to eliminate the need for waterproofing work at the installation location, reduce the effects of solar heat, and satisfy transportation conditions.

The present invention will be explained in detail below with reference to the drawings.

Figure 3 is a plan view of the embodiment of the present invention, and Figure 4 is A of Figure 3.
- It is a cross section of the BCD plane.

This embodiment is assembled from a cylindrical box integrally molded with reinforced plastic material, etc., and several panels with curved surfaces molded with reinforced plastic material, etc., with several ventilation holes 17 provided above and below. Outer shell 13, iron leg 14, and ventilator 1
5, and an entrance/exit door 16 for entering/exiting the outside of the box 12.

A complete set of devices such as a communication device body 20, parabolic antennas 21 and 22, and a lightning rod 23 are housed and incorporated on the iron leg 14.

This storage box consists of the above structure.
The heat dissipated inside the housing box is that the heat generated from the communication device main body 21 housed in the cylindrical box 12 is radiated to the outside from the ventilator 15 as shown by the arrow E shown in FIG. Outer shell 1 assembled from shaped panels
3, but the heat that entered the interior through the outer shell 13 is blocked by the ventilation holes 17 provided above and below the outer shell 13.
Solar radiation heat does not directly affect the interior of the cylindrical box.

In addition, if the equipment mounted inside is adversely affected by cold weather, by blocking the ventilation hole E, the movement between the outer shell 13 and the cylindrical box 12 will be slowed down, and the effect on the internal equipment will be reduced. This results in effective heat retention.

In addition, regarding waterproofing, the box 12 in which the communication device body 20 is housed has an integral structure, and rainwater that enters from the outer shell panel 13 is blocked by the internal cylindrical surface 12, which has no effect on the interior. .

Therefore, there is no need for any waterproofing work on the outer shell 13 at the installation location.

In addition, the outer shell 13 has a streamlined curved surface that is less affected by wind pressure, and can be made lighter.

Further, the outer shell 13 is divided into several panels and has a structure that can be assembled at any location with a certain amount of space.

Moreover, the arrangement of the parabolic antennas 21 and 22 can also be selected at arbitrary positions.

This box 12, outer shell 13, legs 14, and ventilator 15 are
They can be transported disassembled and reassembled at the installation site, satisfying various transportation conditions.

Further, the outer shell including the parabolic antennas 21 and 22 is integrally shaped, and has an excellent structure in terms of appearance.

As explained above, the structure of the present invention is a communication equipment storage box with a double wall structure, which reduces the effects of solar radiation heat, eliminates waterproofing problems on site, reduces wind pressure, and satisfies transportation conditions. However, it has an excellent appearance, and this structure can be widely used as an outdoor structure.
