DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a museum,
The present invention relates to a sunlight collecting device with a smoke exhaust function, which is disposed on a skylight of a building such as an art museum, a public hall, a hospital, and the like.

[0002]

2. Description of the Related Art In the above-mentioned building having an unspecified number of visitors, if the floor area of a room is more than a certain level, smoke emission that emits toxic smoke and gas to the outside in case of a fire should be taken. Equipment installation is required. In addition, the smoke exhaust device is a smoke exhaust device with a ceiling that discharges smoke and the like to the outside through a smoke exhaust duct from a smoke outlet provided on the ceiling, and a smoke exhaust device that is provided on windows and walls to directly emit smoke to the outside. There is a skylight-type smoke exhaust device that is classified as a wall-mounted smoke exhaust device that discharges air.

[0003] A conventional skylight type smoke evacuator has a lower frame provided at a ceiling opening, and an upper frame which can be moved up and down with respect to the lower frame using an X-arm or the like. At normal times, the upper frame is in the lowered position, the ceiling opening is closed by glass or transparent resin provided on the upper frame, and functions as a lighting window,
In the event of a fire, the upper frame is raised to create a gap between the upper frame and the lower frame, and function as a smoke outlet. The lifting and lowering of the upper frame is performed by an automatic opening / closing device that drives the X-arm using a lifting motor.

[0004] On the other hand, as a device for efficiently guiding sunlight from a roof into a room, a solar lighting device is known. This device changes the direction of a built-in flat prism according to the altitude and azimuth of the sun by a rotary driving device using a motor for raising and lowering so that sunlight is most efficiently guided into a room. The ceiling-type smoke exhaust device and the solar lighting device are both devices that can be mounted on a roof, but have conventionally been provided as separate facilities.

[0005]

However, in the case where the ceiling-type smoke exhaust device and the solar lighting device are installed as separate facilities, the structure of the roof becomes complicated, and the cost is increased since the roof is separately installed. In addition, the automatic opening / closing device provided in the smoke exhaust device and the rotary drive device provided in the solar lighting device both require a power source, but when a commercial power source is used, electrical work such as wiring is required. Also contributes to the cost increase. The current operation of the smoke emission function is to be performed manually at the discretion of the staff.However, in the event of an emergency such as a fire, if the staff as maintenance personnel cannot operate the smoke emission function for any reason, For safety, there is also a demand for a fail-safe function that automatically activates the smoke exhaust function.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems (problems) of the prior art, and is an apparatus having a smoke exhaust function and a sunlight collecting function, which is driven without using a commercial power supply. It is an object of the present invention to provide a solar lighting device with a smoke exhaust function capable of performing the above.

[0007]

According to the first aspect of the present invention, there is provided a sunlight collecting apparatus with a smoke exhaust function according to the present invention, wherein the ceiling is formed on a roof of a building. A lower frame attached to the opening, and an upper frame attached to the lower frame so as to be able to move up and down, and the upper frame includes one or a plurality of lighting prisms arranged at predetermined intervals; A transparent cover that covers the lighting prism, a rotation driving device that rotationally drives the lighting prism, and a control device that controls the rotation driving device so that the lighting prism has an appropriate rotation angle according to the position of the sun are provided. And
In addition, a motor for raising and lowering the upper frame by a motor for lifting and lowering, an external power supply for supplying power to the rotary drive device, a control device and an automatic opening and closing device for controlling the vertical movement of the upper frame, and a smoke detection function, Based on the detection signal of the smoke detection function, the automatic opening / closing device is operated to drive the elevating motor to move up and down the upper frame to form a smoke outlet.

In this way, if the lift motor is automatically driven based on the detection signal of the smoke detection function to form the smoke outlet, there is no maintenance person who normally performs the opening / closing operation of the smoke outlet. The smoke detection function is activated as described above even when the detection of a fire or the like is delayed due to distracted time or other work, and even when the detection is not possible, it is effective as a fail-safe function of the smoke discharge function. is there.

According to the second aspect of the present invention, a solar cell is provided as a power supply for power supply instead of the external power supply. When a solar battery is provided as a power supply for power supply in this manner, there is an energy saving effect of saving power consumption by an external power supply.

Further, according to the present invention, a storage battery for storing the power generated by the solar cell is further provided. When the storage battery is attached to the solar cell in this manner, even when the power generation by the solar cell is stopped or reduced at night or when it is cloudy, or when using an external power supply, or when the power is cut off, the power is stored in the storage battery. The smoke detection and the smoke discharge function based on the smoke detection can be smoothly operated by utilizing the electric power.
