A gas cylinder 8 for filling the air bag 7 with compressed air is placed in the vicinity of the air bag 7, and the gas cylinder 8 and the air bag 7 are connected so that air can be fed through a changeover valve 10 and a pipe 11. The other end part of a rotary member 20 provided with a float 19 on one end of a water level detecting element 9 is frought into abutment to a projecting end of a driver 17. A coil spring 18 is compressed, and a moving body 16 is positioned at an intersection point of a right angle pipe part 14 and a horizontal pipe part.

Description

[Detailed description of the invention] The present invention relates to a structure for preventing flooding of electronic equipment.

The electronic equipment 114I and combination equipment are extremely dense,
Because it is composed of moldy parts, it is extremely susceptible to water damage.If it gets wet or exposed to water, the insulation of the electrical parts may deteriorate, and mechanical parts that have been exposed to improper contact may corrode, causing them to not function properly. It disappears.

There is a danger of flooding, especially when installed on the first floor of a bank store or factory, or when installed in a low-lying building.

The causes of flooding are river flooding and torrential rain.

Possible causes include storm surge and tsunami.

Countermeasures can be taken in advance if flooding is predicted or if there are people nearby, but in some cases, such as at night or after people have gone home, it may take time for Kf1 to arrive in time. The present invention provides a flood prevention structure for electronic equipment that automatically detects water intrusion and protects computer equipment from water immersion by 1%.

This objective can be achieved by providing a mechanism to automatically raise submerged electronic equipment between the child equipment and the installation floor.

An embodiment of the present invention will be described below with reference to the attached drawings.

Figures 1 to 6 are for explaining the flood prevention structure according to the present invention. Side view of the condition when the light is flooded - 1 No. 48! A partial sectional view showing the structure 1 for automatically supplying compressed air to the lamp, j115WJ is a perspective view of the airbag when it is deflated, and Figure 6 is the air at the time of j1j It is an fI+ view of the bag.

In these figures, 1 is the electronic equipment, 2 is the installation floor, and 3 is the

As shown in FIG. 1, in the present invention, an electronic device is installed on a poem 2 via a housing push-up mechanism 4.

This push-up mechanism 4 A movable soil support base 5 on which the FX device 1 is placed
8 A lower support base 5' fixed to the floor 2 is formed with a telescopic air bag interposed therebetween. Also, support stand 5.5'
is the support piece 6 whose height moves up and down in order to raise the device stably. j) Connected at the front and back. Further, a cylinder 8 for filling the airbag 7 with compressed air is used to fill the airbag 7 with compressed air.
The cylinder 8 and the air pack 7, which are arranged nearby, are connected to each other through a switching valve 10 and a pipe 117 so as to be able to supply air.

The structure of the switching valve 10 is the horizontal pipe part of the T-shaped pipe 12.
Pipe Ili to l 3! The right-angled tube m1ll: *The pump 8 is connected via the pipe 15. A movable element 16 is enclosed at the intersection of the right-angled tube section 14 and the horizontal tube section, and the movable element 16 is driven. The child 17 is led out to the other end of the horizontal tube section via a compression coil spring 18. At all times, the water level detection element 9 is located at the central protruding end of the drive element 17.
The other end of the rotating member 20 provided with the float 19 is m*, and in this contact state flJ, the coil spring 1
The movable element 16 is compressed by 8 fl and is located at the intersection of the right angle tube s14 and the horizontal tube section.

In state III before flooding in FIG. 1, the boiler 8 is always open, but since the float 19 of the water level detection element 9 is at the solid line position in FIG. child 16
is blocking the supply air of pipe 15LF). Therefore,
The air bag 7rX is not filled with air and is in a folded state as shown in Fig. 1 and Fig. 5.

, When the next flood occurs, float 19 becomes the 41st! The floating member 20 is lifted up as shown by the landing at 11 points, and the rotating member 20 is lever-like.
The pressure on the driver 17 is automatically released.

Then, the drive element 17 slides due to the restoring force of the coil spring 18, and the right angle tube part 141 of the movable element 16 is detached.
let This vCXV cylinder 8 p air is automatically pipe 15 - right angle pipe section 14 - horizontal pipe section no. 1111113

- Supplied with pressure tubes. Then, the airbag 7
Then, the supporting piece 6, which gradually swells up like the 6th mackerel, also rises to a predetermined height as shown in Figures 2 and 3 of the steamer 1. This equipment 1rJ is located above the water level 3 from K and does not produce any sound of flooding.

In addition, air leakage from the expansion hole airbag 7 is done through valve 2.1c No. 6.
This is done by opening (Fig.).

According to the present invention described above, it is possible to prevent electronic equipment from being submerged in water without using human hands, and the practical effects thereof are remarkable.
