Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a water leakage detection device on a car of an elevator, which detects water leakage on a car of an elevator.

[Prior art 1] Conventionally, water leakage detection devices for buildings and equipment have been used, for example, water leakage detectors using water leakage detection wires, and recently disclosed in Japanese Patent Application Laid-Open No. 61-66955 and Japanese Patent Application Laid-Open No. 2-103069. Devices that detect urination, etc. have been proposed.

For example, in a building, if the landing area of each floor of an elevator for a condominium faces the outdoors, seasonal or concentrated rainfall or strong winds may fall directly on the lobby or landing area of the elevator area, or the landing area may fall directly from the machine room to the landing area. Rainwater may flow down the stairs, gradually increasing in volume and flowing into the elevator hoistway.

On the other hand, if the hoistway on the elevator side or the car room is flooded or submerged, it will lead to poor insulation of the electric circuit, lowering the function of the safety circuit, and making the operation extremely dangerous, so stop the operation immediately. or need to take a break. In this case, the car is usually evacuated to the top floor or the next floor (.

However, at the beginning of water leakage or flooding, the amount of water is small.
Water droplets that fall on the car go unnoticed until they fall into the car interior, and it is rare for them to be discovered manually during patrols. In addition, a considerable amount of time had passed before the manager suspended operations due to the discovery and report.

[Problem to be Solved by the Invention 1] As mentioned above, when water leakage or flooding on a passenger car is left to human intervention, it is difficult to quickly detect the occurrence of water leakage. Furthermore, if elevator operations were stopped or water leakage progressed over time, resulting in flooding, there was a considerable financial burden due to the labor required to restore the situation and the time required for the elevator to be stopped. .

This invention was made in view of the above-mentioned problems, and it detects the occurrence of water leaks as soon as possible, issues an automatic alarm, and also automatically suspends operation in order to avoid flooding damage. It provides equipment.

[Means for Solving the Problems] A water leakage detection device on a car according to the present invention includes a detector that detects water droplets due to water leakage on an elevator car, and an alarm that issues an alarm based on the detection signal. and an operation control means for controlling the operation of the elevator to stop.

[Operation] In this invention, when rainwater flows onto the top of the car or onto the canopy, the water droplets short-circuit the water leakage detection wire installed in advance, and the detection signal from the detector is sent to the operation control means, causing the operation to be stopped. At the same time, the alarm buzzer is activated and sounds.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram of a configuration showing an embodiment of the present invention,
Further, FIG. 2 shows a layout diagram of a configuration in which water leakage detection lines are installed on the car.

In both figures, the detector (1) detects water droplets due to water leakage.
The water leakage detection wire (2), which is fixed to the upper beam (13) of the elevator car with a mounting base (4) on one end and connected to the circuit terminal of the detector (1), is connected to the outside of the equipment on the upper beam (5) of the elevator car. It is attached to the main parts such as the box (6) and the canopy (7), and the top of the car (5)
When rainwater flows into the canopy (7), the water droplets (8) short-circuit the water leakage detection line (2) installed in advance at, for example, a short circuit point (9), and the detection signal (10) is sent to the operation control means. (11) to control the suspension of operation, and also energizes and sounds an alarm buzzer (12) disposed on the side of the car.

The operation control circuit (11) includes a top floor stop command circuit (lla
) and a top floor stop determining circuit lb), which controls the car to stop at least at the top floor based on the detection signal (10) from the detector (1).

Here, although there are many devices installed on the top of the car (5), if rainwater flows in from the landing (boarding/exit) on each floor, for example, it will fall into the hoistway and the car will be damaged. Since the leakage detection line (2) can be installed only in the main part of the front end of the top M (7), it is still possible to detect the pressure. The wire (2) may be attached around the device, may be along the lengthwise and horizontally directions, or may be wrapped around the main part.

Therefore, according to the above configuration, when a water droplet (8) falls on the installation surface of the water leakage detection line (2), the electrodes (2a) and (2b) are short-circuited at the short-circuit point (9). )
A detection signal (10) is generated. Based on this detection signal, the alarm buzzer (12) sounds, and the detection signal is taken into the operation control circuit (11) and energizes the top floor stop command circuit (llal) to stop at the top floor and wait until recovery. hold between.

This kind of movement is caused by water droplets falling on the car (8).
If the interior of the elevator hoistway or the elevator car, which is the location where safety is least , is extremely dangerous. Therefore, it is necessary to immediately stop the system or take measures to suspend its operation.

Due to the above-described structure, the above-mentioned embodiment detects this as soon as possible, issues an alarm, and prompts the vehicle to automatically stop to the top floor.

In addition, in the above embodiment, a water leakage detection line (2
), but this water leakage detection line (2) may be installed on the landing side where rainwater tends to flow in when the wind and rain are strong, for example, on the corner of the entrance or on the surrounding wall.

In that case, it is best to connect the detector ( ) with a general instrumentation cable, etc., and also connect the above alarm buzzer (12
) may be taken out to another location (for example, a manager's room) and installed in a location where monitoring can be performed.

Furthermore, the number of circuits of the water leak detection line (2) may be increased to widen or divide the detection range. In addition, it can be used to detect the location of water leakage and inundation around machinery room equipment and in hoistway bits.

[Effects of the Invention] As explained above, according to the present invention, water droplets on the car are detected, the alarm means immediately issues an alarm, and the operation of the elevator is automatically stopped. Avoid dangerous driving caused by flooding and submergence, and
Damage to equipment can be kept to a minimum, and the economic effects associated with restoration are also large.
