Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a ventilation system in a mechanical parking system.

[Prior art]

Generally, in the case of a bottom-entry type, the inside of the tower becomes hot and humid in the summer, so as shown in Figure 2, a louver 2 is provided at the top of the inner wall 1 of the tower, and a ventilation fan 3 is installed there. After installation, the administrator ventilated the inside of the tower by operating a ventilation fan switch (not shown) on an operation panel (not shown).

[Problem that the invention attempts to solve]

However, this method not only increases the burden on the administrator, but also requires a special electric motor and power source for ventilation, and even if the ventilation fan is designed to operate intermittently automatically, there is no need for it. A control circuit had to be installed.

The present invention has been made in view of the above points, and an object of the present invention is to provide a ventilation device that does not require a special drive source.

[Means for solving problems]

The present invention is a mechanical parking device that is driven by an electric motor and has a louver on the inner wall of the tower.The louver is provided with a fan, and the fan is connected to a mechanical device that is driven by the electric motor.

[Effect]

If configured as described above, the fan rotates in conjunction with the operation of the parking device, so ventilation is automatically performed.

〔Example〕

FIG. 1 is a partial cross-sectional view showing one embodiment of the present invention. The same reference numerals as in FIG. 13 is a mounting base for installing the electric motor 11), etc., and 14 is a fan attached to the louver 2, and this fan 14 is connected to the reducer 12 via the shaft 14a, or directly connected to the electric motor 11. (Or connected via a speed increaser)
and is configured to rotate in conjunction with the electric motor 11. Incidentally, the upper sprocket (numeral 4 in FIG. 2, omitted in FIG. 1) that drives the cage is driven by the electric motor 11 via the reduction gear 12 as in the conventional case, but this is not directly related to the present invention. Since there is no such thing, explanation and illustration will be omitted.

[Effect of idea]

With the above configuration, since the fan 14 rotates in conjunction with the operation of the parking device, air intake or exhaust can be automatically performed without requiring a special drive source. With such a device, the ventilation system only works while the parking device is in operation, so
It is economical because it prevents people from forgetting to turn off the switch like in the past, and in the event of a fire, the ventilation fan also stops at the same time as the electric motor stops, allowing for smooth firefighting.

Incidentally, if the fan 14 described above is replaced with an air exhaust fan, it is also possible to configure the parking system so that only the exhaust operation is always performed regardless of which direction the parking device rotates.

In the above explanation, the lower entry type has been taken as an example, but the invention is not limited to this, and can also be applied to an intermediate entry type or an upper entry type. In this type of parking system, the mechanical equipment is installed underground, so exhaust gas accumulates in the underground pit, and when the carbon dioxide fire extinguishing system is activated, carbon dioxide gas is heavier than air, so Natural flow cannot be expected and a forced ventilation system is required, but in this case, the effects of the present invention can be achieved by configuring the fan to work in conjunction with the lower sprocket.
