The water level detector 11 feeds back the information of water immersion to the control unit 99, and the control unit 99 controls the door motor 92, the speed limiting device 81 and the human-computer interaction device 95 to generate corresponding response, reduce the speed to run, inform passengers in the elevator car, make a prompt and control the running interval of the elevator to be an interval excluding the lowest floor and the highest floor. The control switch of the speed limiting device 81 is arranged at a safe height position, and the travel switch 98 of the buffer device and the control device thereof are arranged at a waterless flooding height position, so that electronic components can be prevented from being immersed in water under the condition that the foundation pit is immersed in water, equipment faults caused by the water immersion are avoided, and the safe operation between middle floors under the condition that the foundation pit is immersed in water is ensured.
As shown in fig. 2 and 3, the water level detecting apparatus 11 includes a housing 12 having an inner cavity 13, a water inlet 22 disposed at a bottom end of the housing 12, a floating body 15 disposed at a bottom of the inner cavity, a follower 16 driven to rise when the floating body 15 rises, a movable contact 61 disposed on the follower 16, a fixed contact 66 fixedly disposed at a top of the inner cavity 13, and a two-way lead 68, wherein the two-way lead 68 is connected with the movable contact 61 and the fixed contact 66 respectively and hermetically penetrates through the housing 12. Set up body 15 in fixed mounting's the casing 12, casing 12 below body 15 sets up into water hole 22, and water pours into from water hole 22 when suffering the water logging, thereby makes body 15 come-up drive follower 16 rise, and then moving contact 61 upwards with decide contact 66 contact switch-on, can guarantee that the water level detector is intact when the transmission suffers the feedback signal of water logging, experience the water logging also can not receive the damage, also can repeat effective use.
Furthermore, a sealing partition plate 31 which divides the inner cavity 13 into an upper cavity 32 and a lower cavity 33 is arranged in the shell 12, so that only the lower cavity 33 where the water inlet hole 22 is located can be filled when water is immersed into the water, and the upper cavity 32 is used for placing electronic components and cannot enter the water, thereby ensuring that the water level detector cannot be damaged even if the water is immersed into the water during the use process. The top of the lower cavity 33 allowing water to be poured in can be provided with an air hole, so that air can be exhausted when water enters, air can be supplemented when water is drained, the height of the water level can be reflected in real time, the water level inside the lower cavity is consistent with the water level outside the lower cavity in the corresponding water level interval, and the water level difference between the inside and the outside caused by the existence of the internal air pressure is avoided.

The floating body 15 generally comprises a low-density foam body 55, and the upper side of the foam body 55 is provided with an active magnet 52.
When the water level drops after the water immersion subsides, the water in the shell 12 flows back, the floating body 15 and the driving magnet 52 sink and fall under the action of gravity, the follower 16 losing the jacking action of magnetic repulsion also falls under the action of gravity, the water level alarm circuit is disconnected, and the feedback signal disappears. The whole water level detector can be recovered to the initial state for reuse.
The moving contact 61 includes a conductive sheet 63 and at least two pins 64 with one end fixed to the conductive sheet, the fixed contact 66 is provided with an insert plate adapted to the pins, the raised moving contact 61 makes the pins 64 on the conductive sheet 63 upwards insert into the insert plate to form an electric signal conduction, a loop of a trigger signal is formed, and the trigger signal passes through the shell 12 through a lead 68 in a sealing manner to transmit a water immersion signal.

Or can be separated into two independent water level detectors.
In actual implementation, the water level detectors have two groups of devices for detecting the water level. The detector adopts a plastic round pipe as a shell, is waterproof and rustproof, and is provided with two rows of long round holes for accumulated water to enter the detector. The inside of the water level detector is divided into two groups of detection, namely 6 layers, and each group comprises 3 layers. The first layer of each group is a water inlet layer, the second layer is provided with a low-density high-buoyancy material combined magnet (with the positive pole upward), and the third layer is provided with a magnet (with the positive pole downward), foam, a thin copper sheet and a switch. When the accumulated water is full to a certain degree, the buoyancy material on the second layer floats upwards along the guide rod, and after the reverse stress of the two magnets acts, the magnet on the third layer (with the copper sheet and the switch contact pin) moves upwards under the thrust until the switch contact pin and the switch socket are closed. The space between the water inlet layer and the second layer is provided with a floating body base plate for blocking, the floating body base plate 25 is provided with a through hole 26, and the two layers form a lower cavity; the third layer is an upper cavity.
During concrete implementation, the water level detection instrument is installed at the elevator pit, and first group detection device establishes within the pit height 500mm, and when foundation ditch ponding was full to 500mm, the buoyancy material in the second floor of first group detection instrument upwards pushed up, reached the like poles repulsion scope of magnet group, and the third layer magnet of first group detection instrument received the counter-force upwards to suspend this moment, switch contact pin and switch socket contact circular telegram.
