Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
Refer to fig. 1-7. The embodiment of the utility model discloses automatic audible and visual alarm device that opens door that elevator toe guard position exceeds standard, including photoelectric switch 31 and first display screen 32 of fixed mounting on toe guard 3, fixed mounting is at sound alarm 21 and the second display screen 22 in elevator cab 2, and the relay of being connected with photoelectric switch 31 electricity, sound alarm 21, first display screen 32 and second display screen 22 are connected with the relay electricity respectively, when photoelectric switch 31 measuring distance surpassed the default, trigger the relay so that sound alarm 21, first display screen 32 and second display screen 22 send out the police dispatch newspaper.
Specifically, the sound alarm 21 is a buzzer.
Specifically, the alert issued by the first display screen 32 includes a circular scrolling caption.
Specifically, the alert issued by the second display screen 22 includes a circular scrolling.
Specifically, the first display screen 32 and/or the second display screen 22 are LED display screens.
Specifically, the automatic sound and light alarm device for opening the door when the position of the elevator toe guard exceeds the standard further comprises a 12V direct-current power supply (which can share the intercom power supply of the elevator emergency lamp).
Specifically, the relay is connected to the audio alarm 21, the first display 32, and the second display 22 via three-way switches (a, b, c in fig. 2).
Specifically, the preset value of the present embodiment is greater than or equal to 25cm, and less than or equal to 30 cm. For example, the preset value may be set to 30 cm.
The embodiment of the utility model provides a theory of operation as follows:
referring to fig. 6 and 7, when the elevator car 2 is in a normal flat-bed state, the toe guard 3 or the photoelectric switch 31 is under the landing, the relay cannot be triggered whether the elevator door is opened or closed, because the distance measured by the photoelectric switch 31 is always smaller than the preset value of 30cm at the moment, the hoistway is in a closed state, and the elevator cannot give out sound and light alarm.
Referring to fig. 4 and 5, when the elevator car 2 is in an uneven floor state, the toe guard 3 is out of standard and a hoistway hole 4 is formed at the elevator shaft opening. If the hall door 1 is closed, the distance measured by the photoelectric switch 31 is still less than the preset value of 30cm, and an audible and visual alarm cannot be triggered, if the hall door is opened illegally (no matter trapped people or rescue personnel illegally open the hall door), the distance measured by the photoelectric switch 31 is far more than 30cm, so that the relay executes the following actions:
a. after the first switch of the relay is closed, the first switch is electrified and a sound alarm 21 (namely a buzzer) gives an alarm;
b. after the second switch of the relay is closed, the second display screen 22 is driven to display a circulating rolling caption, for example, "a person trapped in a ladder hears a buzzing alarm to stay in a car, illegally opens a hall door, and is easy to fall down when jumping forcibly";
c. after the third switch of the relay is closed, the first display screen 32 is driven to display the circulating rolling caption, for example, "rescue is suspended by the rescuers, and then rescue is carried out after the barring is flat.
Referring to fig. 3, it is a schematic diagram of the operation of the present embodiment. When the position of the elevator toe guard exceeds the standard, the hall door is not opened, the sound and light alarm is not triggered at the moment, and the elevator is in the state shown in figure 4; if the rescue worker opens the hall door at the moment, the distance measured by the photoelectric switch is larger than a preset value, an audible and visual alarm is triggered at the moment, and the elevator is in a state shown in fig. 5; the landing door is closed, and the elevator is in the state shown in fig. 6 by the flat layer to be turned; at the moment, the rescue personnel open the hall door, the elevator is in the state shown in figure 7, the acousto-optic alarm cannot be triggered, and the rescue conforms to the safe operation.
The embodiment of the utility model provides an automatic audible and visual alarm device that opens door that elevator toe guard position exceeds standard, when toe guard position exceeds standard, in case illegal door of opening hall (no matter stranded personnel or rescue personnel illegal door of opening hall) then can send out audible and visual alarm in real time, real-time audible and visual alarm tradition marking slogan has better warning effect to remind people (including stranded personnel and rescue personnel) to abide by normal rescue flow, reduce the probability of rescue in-process emergence accident.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
