[0028] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0030] like Figure 1 As shown, this embodiment discloses a water-filling detection device for elevator landing doors. The device is installed on the lowest floor of the elevator or on all floors with a basement. It can detect whether water flows into the elevator shaft from the landing door 800 position. The device includes a water baffle 100, adjusting bolts 200, a nut assembly 300, an elastic element 400, an actuating plate 500, and a monitoring switch 600. The water baffle 100 blocks water flow at the door gap 800a and can slide relative to the landing door 800 as water flows. The adjusting bolts 200 are used to install the various components on one side of the landing door 800. The nut assembly 300 is used for the installation and limiting of the elastic element 400 and the actuating plate 500. The monitoring switch 600 is activated by the actuating plate 500 when water enters the elevator and generates a corresponding signal. Upon receiving the signal, the elevator control system takes appropriate emergency measures.

[0031] It should be noted that, as Figure 1 As shown, in this embodiment, the door gap 800a refers to the gap between the elevator landing door frame 900 and the landing door 800. Water will generally flow into the elevator shaft through this gap.

[0032] like Figure 2As shown, the baffle plate 100 in this embodiment is provided with a baffle surface 100a; in the sliding direction of the landing door 800, the baffle surface 100a is correspondingly provided with the door gap 800a, and the baffle surface 100a can block the door gap 800a. When water flows into the elevator shaft from the door gap 800a, the baffle plate 100 blocks the water flow, and the water flow can push the baffle plate 100 to slide, specifically along the sliding direction of the landing door 800. In this preferred embodiment, the baffle plate 100 includes a horizontal plate 110 and two vertical plates 120. The two vertical plates 120 are vertically connected to both ends of the horizontal plate 110 to form a U-shaped structure. The inner circumferential surface of the U-shaped structure facing the door gap 800a is configured as the baffle surface 100a. Specifically, the horizontal plate 110 is vertically arranged on one side of the landing door 800. One vertical plate 120 is vertically connected to one end of the horizontal plate 110 in the horizontal direction and is located between the door frame 900 and the horizontal plate 110. The other vertical plate 120 is vertically connected to the other end of the horizontal plate 110 in the horizontal direction and is located between the landing door 800 and the horizontal plate 110. From a top view, the horizontal plate 110 and the two vertical plates 120 are connected to form a U-shaped structure. In this embodiment, the horizontal side of the horizontal plate 110 facing the landing door 800 and the horizontal side of the vertical plate 120 facing the landing door 800 form the water-blocking surface 100a, and at least a portion of the water-blocking surface 100a corresponds to the sliding direction of the door gap 800a in the landing door 800.

[0033] In this embodiment, the baffle plate 100 is set as a U-shaped structure, which can completely block the water flow into the well at the door gap 800a position and can relatively accurately monitor the water pressure entering the well.

[0034] like Figure 2 As shown, in some embodiments, the lower surfaces of the horizontal plate 110 and the two vertical plates 120 are in sliding contact with the upper surface of the door sill 700 to prevent water from flowing away from under the horizontal plate 110 and the two vertical plates 120. In some preferred embodiments, one side of one vertical plate 120 is in contact with the door frame 900, and the inner side of the other vertical plate 120 is in contact with the landing door 800. Furthermore, the door frame 900, the horizontal plate 110, the vertical plates 120, the door sill 700, and the landing door 800 enclose a relatively enclosed space at the door gap 800a, that is, the internal space of the U-shaped structure. This internal space of the U-shaped structure can completely contain the water flow at the door gap 800a, preventing pressure leakage at this location and avoiding monitoring failure under low water pressure infiltration.

[0035] like Figure 2As shown, in some embodiments, the landing door 800 is slidably disposed within the groove 710 of the door sill 700 via a slider disposed on its lower surface. An extension plate 130 is disposed on the lower surface of the horizontal plate 110, extending into the groove 710 to prevent water from flowing away from below the baffle plate 100 through the groove 710. Preferably, the outer periphery of the extension plate 130 slides in contact with the inner periphery of the groove 710 to achieve complete sealing of the groove 710. Specifically, the lower surface of the extension plate 130 slides in contact with the inner bottom surface of the groove 710, and the two horizontal sides of the extension plate 130 slide in contact with the two inner sidewalls of the groove 710, respectively. It should be noted that because the extension plate 130 slides in contact with the inner periphery of the groove 710, the extension plate 130 does not obstruct the overall sliding of the baffle plate 100.

[0036] like Figure 3 As shown, the adjusting bolt 200 passes through the landing door 800 along the sliding direction of the landing door 800, and the adjusting bolt 200 can slide relative to the landing door 800. Specifically, the vertical rib 810 on the back side of the landing door 800 is provided with a guide sliding hole, through which the adjusting bolt 200 slides. The axial direction of the adjusting bolt 200 is configured to be the sliding direction of the landing door 800, and the guide sliding hole can guide the adjusting bolt 200 to slide. One end of the adjusting bolt 200 is connected to the baffle plate 100. The adjusting bolt 200 can be fixedly connected to the baffle plate 100, or the adjusting bolt 200 can pass through the horizontal plate 110 of the baffle plate 100, and the head of the adjusting bolt 200 can prevent the baffle plate 100 from detaching from the adjusting bolt 200. When the baffle plate 100 is pushed by the water flow, the adjusting bolt 200 can slide along with the baffle plate 100.

[0037] like Figure 3 As shown, the nut assembly 300 is threaded onto the other end of the adjusting bolt 200. The nut assembly 300 is used to limit the elastic element 400 and to install the actuating plate 500. In the sliding direction of the landing door 800, the nut assembly 300 and the baffle plate 100 are located on both sides of the vertical rib 810, respectively.

[0038] like Figure 4 As shown, the elastic element 400 is disposed between the landing door 800 and the nut assembly 300. The elastic element 400 provides elastic preload for the movement of the adjusting bolt 200. That is, only when the water pressure is greater than the preload of the elastic element 400 can the baffle plate 100 slide in the sliding direction of the landing door 800, and the actuating plate 500 will move accordingly. In this way, the monitoring switch 600 will only respond and activate the corresponding safety measures when the water pressure is relatively high. In some preferred embodiments, the elastic element 400 is preferably a spring, which is coaxially sleeved on the adjusting bolt 200, with one end of the spring abutting against the side of the nut assembly 300 and the other end of the spring horizontally abutting against the vertical rib 810 on the back side of the landing door 800.

[0039] like Figure 3 and Figure 4 As shown, the nut assembly 300 includes a first nut 310 and a second nut 320. Both the first nut 310 and the second nut 320 are threaded onto the adjusting bolt 200. Both the first nut 310 and the second nut 320 are located on the side of the elastic member 400 opposite to the vertical rib 810. The axial side of the first nut 310 abuts against the elastic member 400. When the first nut 310 is turned, the compression of the elastic member 400 can be adjusted. One end of the actuating plate 500 is clamped between the other axial side of the first nut 310 and the second nut 320. The clamping action of the first nut 310 and the second nut 320 enables the actuating plate 500 to be installed. When the adjusting bolt 200 slides along with the baffle plate 100, the actuating plate 500 slides together.

[0040] like Figure 4 As shown, one end of the actuating plate 500 is connected to the nut assembly 300, specifically, one end of the actuating plate 500 is clamped between the first nut 310 and the second nut 320. The other end of the actuating plate 500 is correspondingly set to the trigger end 610 of the monitoring switch 600, specifically corresponding to the sliding direction of the landing door 800. When the actuating plate 500 is driven to slide by the adjusting bolt 200, the actuating plate 500 can contact the trigger end 610 and act on the trigger end 610. In this embodiment, preferably, the actuating plate 500 includes a main body 510, a connecting part 520, and a push plate part 530; the connecting part 520 and the push plate part 530 are respectively set at both ends of the main body 510. The connecting part 520 is clamped between the first nut 310 and the second nut 320. The push plate part 530 and the trigger end 610 are correspondingly set to the sliding direction of the landing door 800, and are used to push the trigger end 610 in the sliding direction of the landing door 800 so that the monitoring switch 600 generates a corresponding signal.

[0041] like Figure 4 As shown, the monitoring switch 600 is located on the back side of the landing door 800, and is correspondingly positioned to the actuation plate 500 (specifically, the push plate part 530). The monitoring switch 600 is communicatively connected to the elevator control system. In this embodiment, the monitoring switch 600 is preferably configured as a limit switch, and more preferably as a waterproof, non-automatic reset micro limit switch. Limit switches allow the response stroke to be set according to actual needs, improving the flexibility of the detection device.

[0042] One working principle of the irrigation detection device in this embodiment is as follows:

[0043] 1. Install at least two water filling detection devices of this embodiment on the horizontal sides of the door 800 respectively;

[0044] 2. When water enters the elevator shaft from the door gap 800a of the elevator landing door 800, if the pressure of the water flow can overcome the preload of the elastic element 400, the water flow will push the baffle plate 100 to slide away from the landing door 800, and the adjusting bolt 200 and the actuating plate 500 will move together with the baffle plate 100 in the sliding direction of the landing door 800.

[0045] 3. Since the monitoring switch 600 and the actuating plate 500 are correspondingly set, when the actuating plate 500 slides, it will contact the trigger end 610 of the monitoring switch 600 and apply force to the trigger end 610. After the response stroke of the monitoring switch 600 is reached, the monitoring switch 600 sends a signal to the elevator control system, which then controls the elevator to perform corresponding emergency operations. Emergency operations include:

[0046] The elevator immediately cancels all in-car command signals and floor call signals. Elevators traveling downwards stop at the nearest floor without opening the doors and then travel in the opposite direction to the top or middle floor. Elevators stopped at the bottom floor quickly and automatically travel to the top or middle floor. Elevators traveling upwards stop at the nearest floor without opening the doors and then travel in the same direction to the top or middle floor. Once the elevator doors open, the elevator stops, and a voice prompt inside the elevator car reassures passengers that the elevator safety protection has been activated and asks passengers to evacuate the elevator car safely and orderly.

[0047] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
