Abstract

An elevator pit entry control device comprising: the water level detector is arranged in a pit of the elevator shaft to detect whether accumulated water in the pit of the elevator reaches a preset water level; and a processing module for stopping the elevator to a specified floor which is not the bottom floor and the top floor based on the water level detector detecting that the accumulated water in the elevator pit reaches a preset water level.

Description

Control device for water inflow of elevator pit

Technical Field

The utility model relates to a controlling means that elevator pit was intake.

Background

An elevator is a vertical elevator powered by an electric motor and used for carrying people or goods in a multistorey building. Due to various reasons, water can be accumulated in an elevator pit, so that elevator devices are damaged or rusted, electrical elements are failed, and even passengers are injured or killed in severe cases.

SUMMERY OF THE UTILITY MODEL

The utility model provides a controlling means that elevator pit was intake, include: the water level detector is arranged in a pit of the elevator shaft to detect whether accumulated water in the pit of the elevator reaches a preset water level; and a processing module for stopping the elevator to a specified floor which is not the bottom floor and the top floor based on the water level detector detecting that the accumulated water in the elevator pit reaches a preset water level.

Advantageously, the control device further comprises an alarm module which alarms based on the water level detector detecting that water is entering the elevator pit.

Advantageously, the water level detector comprises a low level detector which triggers when the water accumulation in the elevator pit reaches a low level and a high level detector which triggers when the water accumulation in the elevator pit reaches a high level.

Advantageously, in the temporary use step of the building, when the accumulated water in the pit of the elevator reaches the low water level but does not reach the high water level, the low water level detector is triggered, the processing module keeps the elevator moving normally, and the alarm module sends out an alarm signal; when the accumulated water in the elevator pit reaches a high water level, the high water level detector is triggered, the processing module enables the elevator to stop to an appointed floor, and the alarm module sends out an alarm signal.

Advantageously, in the property ladder only the low water level detector is operated, when the water accumulation in the elevator pit reaches a low water level, the low water level detector is triggered, the processing module stops the elevator to the designated floor, and the alarm module sends out an alarm signal.

Advantageously, the low water level is 30 mm.

Advantageously, the high water level is 120 mm.

Advantageously, the alarm module is a sound and light alarm module.

Drawings

The advantages and objects of the present invention will be better understood from the following detailed description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the relationship of the various components. In the drawings:

fig. 1 shows a block diagram of a control arrangement for elevator pit entry according to the invention.

Detailed Description

Various embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Here, it is to be noted that, in the drawings, the same reference numerals are given to constituent parts having substantially the same or similar structures and functions, and repeated description thereof will be omitted. The terms "first direction", "second direction", etc. herein are described with respect to the drawings of the present invention, unless otherwise specified. The term "sequentially comprising A, B, C, etc" merely indicates the order of the included elements A, B, C, etc. and does not exclude the possibility of including other elements between a and B and/or between B and C. The description of "first" and its variants is merely for the purpose of distinguishing between the parts and does not limit the scope of the invention, which can be written as "second" and so on without departing from the scope of the invention.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of the respective portions and the mutual relationships thereof.

Hereinafter, referring to fig. 1, a preferred embodiment according to the present invention is described in detail.

As shown in fig. 1, the control device for controlling the water entering the pit of the elevator according to the present invention comprises a water level detector 1, a processing module 2 and an alarm module 3 (e.g., an audible and visual alarm module). A water level detector is disposed in the elevator hoistway pit to detect whether the standing water in the elevator pit reaches a predetermined water level. The processing module 2 stops the elevator to a designated floor, which is not the bottom floor and the top floor, based on the water level detector detecting that the water accumulation in the elevator pit reaches a predetermined water level, while the alarm module emits an alarm signal (e.g. sound, light or image).

The water level detector includes a low water level detector 11 and a high water level detector 12. In the temporary use step section of the building, when the accumulated water in the pit of the elevator reaches a low water level but does not reach a high water level, the low water level detector triggers, the processing module keeps the elevator to normally operate, and the alarm module sends out an alarm signal; when the accumulated water in the elevator pit reaches a high water level, the high water level detector is triggered, the processing module enables the elevator to stop to an appointed floor, and the alarm module sends out an alarm signal. . In the property ladder stage, only the low water level detector operates, when accumulated water in a pit of the elevator reaches a low water level and the low water level detector is triggered, the processing module enables the elevator to stop at an appointed floor, and meanwhile, the alarm module sends out an alarm signal. For example, the low water level detector is triggered when the water level exceeds 30mm, and the high water level detector is triggered when the water level exceeds 120mm, but it should be understood that a person skilled in the art can freely select the low water level and the high water level according to actual situations.

Through the utility model discloses a controlling means and control method that elevator pit was intake can detect the ponding condition in the elevator pit at building interim ladder stage and the ladder stage for property reliably to in time send alarm signal, make the elevator stop at appointed floor in order sparse passenger simultaneously, the door opening button keeps normal function in the car, in order to prevent the car or to heavily contact with water, appointed floor is not top layer or bottom.

Moreover, the technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention to achieve the aim of the invention.
