Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing flooding of an elevator.

[0002]

2. Description of the Related Art Generally, in an elevator installed in an open corridor-type apartment building, rainwater blows into a landing when a heavy rainfall rains, and the rain flows into a sill groove for guiding a hatch door. A hole for removing dust and the like falling into the sill groove is provided at the bottom of the sill groove. As a result, the rainwater that had flowed into the sill ditch from the hole entered the hoistway and scattered around the doors on the lower floors and on the cars.

[0003]

In the elevator installed in the above-mentioned conventional open corridor type apartment, door opening and closing abnormalities occur due to rain water splashing around the door,
There have been problems such as rust on the design parts of the car.

It is an object of the present invention to provide an elevator flood prevention device which can solve the above problems with a simple configuration.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rainwater receiving container which is installed below a sill groove for guiding a hatch door and receives rainwater falling from a hole provided at the bottom of the sill groove. A first flexible water pipe that guides overflowing rainwater to the bottom of the hoistway; a water tank installed at the bottom of the hoistway for storing rainwater from the first water pipe;
A configuration in which at least a flexible second water pipe for draining rainwater from the first water pipe is provided in a drainage facility on a lower floor different from the floor provided with the hatch door connected to the water pipe. Is achieved by

[0006] According to this configuration, the rainwater flowing into the sill groove from the landing side is collected in the rainwater receiving container from the hole provided at the bottom of the sill groove. The rainwater overflowing from the rainwater receiving container is stored in the water tank by the first water pipe. By connecting the second water pipe to the first water pipe before the rainwater accumulates in both the rainwater receiving container and the water tank, even if a large amount of rainwater flows from the landing side, the rainwater flows out to the drainage facility. It is possible to prevent rainwater from being scattered on the car or from being stored directly on the bottom of the hoistway.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a flood prevention device 2 installed in an elevator 1 installed in an open corridor type apartment building
Is a rainwater container 3, a first water pipe 4, a second water pipe 5,
A water tank 6, a water detection sensor 7, and a flood alarm device 8 are provided. At the inner bottom of the hoistway 9 of the elevator 1, a portable water tank 6 is installed. The rainwater receiving container 3 is fixed to a header cover 11 provided above the hatch door 10 on the lowest floor of the elevator 1. It is preferable that the rainwater receiving container 3 has a grind shape.
The sill groove 13 for guiding the hatch door 12 provided on the floor immediately above the lowest floor of the elevator 1 has one or more holes 1
4, 14A are provided. The holes 14 and 14A are for removing dust entering the sill groove 13.
The rainwater receiving container 3 is provided so as to receive rainwater that has fallen from the holes 14 and 14A of the sill groove 13. As shown in FIG. 3, the upper end of a first water guide pipe 4 made of a flexible material is
5 is fixed. The lower end of the first water conduit 4 is usually housed in the water tank 6. As shown by the dotted line in FIG. 1, the second water pipe 5 is connected to the first water pipe 4 when the rainwater becomes strong and the rainwater flowing toward the landing increases. The second water pipe 5 may be connected to the lower end of the first water pipe 4 in a watertight manner using a connector, or may be connected to the first water pipe 5 via a switching valve. Flood warning device 8
Is connected to the water detection sensor 7 via wires 16 and 16A as shown in FIG. When the water detection sensor 7 detects water in the rainwater receiving container 3, a signal is issued to activate the flood alarm device 8. The flood alarm device 8 is installed on the header cover 11, similarly to the rainwater receiving container 3. When the inundation warning device 8 is operated, either a sound indicating that “rainwater overflows” or a display indicating that “rainwater overflows” is performed, or one or both of them are performed.

In the above configuration, when the rain wind becomes strong and rainwater is blown into the landing, the rainwater falls into the rainwater receiving container 3 from the holes 14 and 14A of the sill groove 13 and is stored in the rainwater receiving container 3. Can be When the rainwater accumulated in the rainwater receiving container 3 reaches the connection port 3A with the first water pipe 4, the rainwater overflows from the connection port 3A to the first water pipe 4 side. Rainwater overflowing to the first water pipe 4 flows down the first water pipe 4 and falls into the water tank 6. On the other hand, when rainwater overflows to the first water pipe 4 side, the water detection sensor 7 detects the rainwater and sends a signal to the inundation alarm device 8 side. Flood warning device 8
When receiving the signal from the water detection sensor 7, the display indicating "rainwater overflows" is performed or an alarm sound is issued. Therefore, the display or the warning sound allows the maintenance staff or the like to know that the rainwater has started to overflow from the rainwater receiving container 3. Therefore, before the rainwater is filled in the water tank 6, the first water pipe 4 is not filled. Is connected to the drainage facility by the second water pipe 5.
The rainwater falling from the third holes 14, 14A can be drained. In this way, the rainwater flowing into the sill groove 13 from the landing side can be stored in the rainwater receiving container 3 and the water tank 6 or can be discharged to the drainage facility side by the second water pipe 5, so that the rainwater in the hoistway 9 It is possible to prevent the splatter from flying on the car that moves up and down the hoistway 9.

[0010]

As described above, according to the present invention, with a very simple structure, it is possible to prevent rainwater flowing from the landing from entering the hoistway through the holes in the sill grooves and scattering, and the parts around the door can be prevented. An inundation prevention device for elevators that can prevent breakdown and rusting of parts around cars and cars was obtained.
