Description

Technical Field

[0001] This invention is an IoT wireless monitoring system for elevator water immersion, belonging to the technical field of elevator IoT monitoring. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for carrying people or goods in multi-story buildings. The elevator shaft is the shaft through which the elevator is installed. Since the bottom of the elevator shaft is located underground, and electrical components such as the lifting motor and buffers are also installed at the bottom of the elevator shaft, it is particularly important to keep the elevator shaft dry and clean. Normally, water seepage into the elevator shaft comes from seepage from the shaft wall or the spread of surface water into the elevator shaft. Therefore, drainage pipes need to be installed at the bottom of the elevator shaft to introduce water into a specific collection tank and drain the water out of the elevator shaft.

[0003] Because elevator shafts are small, enclosed spaces, it is difficult for people to locate water seepage points within them. Furthermore, the drainage outlets at the bottom of elevator shafts are often covered by debris, affecting drainage. In severe cases, large amounts of water can accumulate in the elevator shaft, causing elevator malfunctions. To address these issues, some technicians in this field have developed an IoT wireless monitoring system for elevator water seepage to overcome the problems mentioned in the background. Summary of the Invention

Detailed Implementation

[0020] like Figure 1 and Figure 2 As shown, an elevator water immersion IoT wireless monitoring system includes an elevator shaft 1, an elevator 2 running inside the elevator shaft 1, far-infrared cameras 3 installed on the outer walls of the elevator 2, a level gauge 4 installed at the bottom of the elevator shaft 1, a water collection tank 15 installed on one side below the bottom of the elevator shaft 1, a drainage pipe 21 connecting the water collection tank 15 and the bottom of the elevator shaft 1, a filter screen installed at the drain outlet above the drainage pipe 21, and a rotary flow meter 14 installed on the drainage pipe 21.

[0021] A hydraulic cylinder 8 is also installed inside one side of the elevator shaft 1. A collection basket 6 is connected to the end of the hydraulic cylinder 8. The collection basket 6 is shaped like a winnowing basket. The basket wall of the collection basket 6 has a mesh structure. The front end of the collection basket 6 extends to the bottom surface of the elevator shaft 1. A rotating column 9 is erected on the lower surface of the collection basket 6. There are two sets of rotating columns 9 facing each other. The surface of the rotating column 9 is equipped with traveling wheels 10.

[0022] A cleaning column 11 runs through the upper part of the basket wall of the collection basket 6. Cleaning brushes 7 are evenly distributed on the surface of the cleaning column 11. A cleaning gear 12 is fixed to one end of the cleaning column 11. A drive gear 13 is provided below the cleaning gear 12. The cleaning gear 12 and the drive gear 13 are connected by a chain. The drive gear 13 is fixed to the end of a rotating column 9 in front of the collection basket 6. An opening and closing assembly is provided between the drive gear 13 and the walking wheel 10 on the surface of the rotating column 9.

[0023] The opening and closing assembly includes an opening and closing cylinder 16, a spring 18 is provided between the opening and closing cylinder 16 and the traveling wheel 10, the opening and closing cylinder 16 is hollow, the rotating column 9 is located inside the hollow opening and closing cylinder 16, a first groove is provided on the inner wall of the opening and closing cylinder 16, the first groove is arc-shaped, and a cylinder 19 is also provided in the first groove, the cylinder 19 is fixed to the surface of the rotating column 9.

[0024] The hollow opening and closing cylinder 16 is also provided with a drive column 17, and a drive gear 13 is fixedly connected to the surface of the drive column 17. The surface of the drive gear 13 is also provided with a second groove, which is arc-shaped. An opening and closing column 20 is also provided in the second groove, and the opening and closing column 20 is fixedly connected to one end of the opening and closing cylinder 16.

[0025] When a large amount of water rushes into the bottom of elevator shaft 1, the accumulated water at the bottom of elevator shaft 1 flows into the water collection tank 15 through the drainage pipe 21. The level gauge 4 detects the water level at the bottom of elevator shaft 1, and the rotary flow meter 14 detects the drainage flow rate of the drainage pipe 21. When the water level at the bottom of elevator shaft 1 is deep enough, but the drainage flow rate of the drainage pipe 21 is very small, it indicates that there is debris covering the drain outlet above the drainage pipe 21. Then, the hydraulic cylinder 8 is activated, driving the collection basket 6 to move towards the drain outlet above the drainage pipe 21 at the bottom of elevator shaft 1. The traveling wheels 10... As the rotating column 9 rotates, the cylinder 19 on the surface of the rotating column 9 moves in the first groove. Under the action of the spring 18, the opening and closing cylinder 16 moves closer to the drive gear 13, so that the opening and closing column 20 at one end of the opening and closing cylinder 16 extends into the second groove on the surface of the drive gear 13, thereby driving the drive gear 13 to rotate together. The drive gear 13 drives the cleaning gear 12 to rotate through the action of the chain. The rotation of the cleaning gear 12 drives the cleaning brush 7 to rotate, sweeping the debris above the drain outlet of the drainage pipe 21 at the bottom of the elevator shaft 1 into the collection basket 6.

[0026] When the debris at the drain outlet above the drainage pipe 21 at the bottom of elevator shaft 1 is cleaned, the rotary flow meter 14 detects that the drainage flow of the drainage pipe 21 is normal. The hydraulic cylinder 8 starts to retract, driving the collection basket 6 away from the drain outlet above the drainage pipe 21 at the bottom of elevator shaft 1. The traveling wheel 10 and the rotating column 9 rotate in opposite directions. The cylinder 19 on the surface of the rotating column 9 moves in opposite directions in the first groove of the opening and closing cylinder 16. The compression spring 18 deforms, causing the opening and closing cylinder 16 to move away from the drive gear 13. The opening and closing column 20 at one end of the opening and closing cylinder 16 is moved out of the second groove of the drive gear 13. The drive gear 13 and the cleaning brush 7 stop rotating to prevent the cleaning brush 7 from rotating in the opposite direction, and the debris is swept out of the collection basket 6.

[0027] like Figure 1 and Figure 3 As shown, a transmission structure 5 is also fixed to the lower surface of the elevator shaft 1. The transmission structure 5 includes module M1, module M2, and module M3. Module M3 is a network switch, model MERCURY S105C.

Module M2 is a network port to serial port module, model ZQWL-GE100D. Pin 1 of module M2 is connected to pin 1 of module M1, and pin 2 of module M2 is connected to pin 2 of module M1. Module M1 is a wireless transmission module, model ZQWL-LCOM101M. The far-infrared camera 3 follows the elevator 2 as it ascends and descends, capturing images of the surface of the elevator shaft 1 wall in real time. When there is a water immersion point on the surface of the elevator shaft 1 wall, the temperature of the water immersion point is lower than the temperature of its surroundings. The far-infrared camera 3 transmits the water immersion point to module M1 through module M2 and module M3, and then transmits it wirelessly outward through module M1.

[0030] Pin 23 of chip U1 is connected to one end of resistor R9, one end of capacitor C6, and one end of inductor L2. The other end of resistor R9 and the other end of capacitor C6 are connected to ground. The other end of inductor L2 is connected to pin 2 of module M4. Module M4 is a wireless receiver module with model number ZQWL-LCOM101M. Pin 4 of module M4 is connected to ground. Pin 5 of module M4 is connected to a +24V power supply. Pin 24 of chip U1 is connected to one end of resistor R8, one end of capacitor C5, and one end of inductor L1. The other end of resistor R8 and the other end of capacitor C5 are connected to ground. The other end of inductor L1 is connected to pin 1 of module M4.

[0031] Pin 25 of chip U1 is connected to pin 1 of chip U2 and one end of capacitor C4. Chip U2 is an integrated operational amplifier, model number LF351. The other end of capacitor C4 is connected to one end of resistor R2 and pin 2 of chip U2. Pin 3 of chip U2 is connected to one end of resistor R3. The other end of resistor R3 is connected to ground wire via pin 4 of chip U2. Pin 8 of chip U2 is connected to a +5V power supply.

[0033] Module M4 receives the water immersion points on the surface of the elevator shaft wall from module M1 via wireless transmission. The data is then transmitted to chip U1 via pins 23 and 24. Chip U1 records the coordinates of the water immersion points on the surface of the elevator shaft wall, allowing operators to query the coordinates of these points and facilitating maintenance personnel in inspecting and repairing them.

[0034] When the voltage at pin 3 of chip U3 is greater than the voltage at pin 2 of chip U3, it indicates that the water level setting at the bottom of the elevator shaft is greater than the water flow setting of the rotary flow meter. Therefore, pin 1 of chip U3 outputs a high level, activating the integrating circuit composed of chip U2. After the set integration time is reached, pin 1 of chip U2 outputs a high level, which is transmitted to chip U1 via pin 25. Chip U1 then issues a command: pin 9 of chip U1 outputs a high level, and pin 10 of chip U1 outputs a low level. Optocoupler chip U3 is turned on, and optocoupler chip U4 is turned off. The hydraulic cylinder extension signal YAGK is connected to the +48V power supply, and the hydraulic cylinder starts extending. Conversely, when the voltage at pin 3 of chip U3 is less than the voltage at pin 2 of chip U3, pin 9 of chip U1 outputs a low level, and pin 10 of chip U1 outputs a high level. Optocoupler chip U3 is turned off, and optocoupler chip U4 is turned on. The hydraulic cylinder retraction signal YAGG is connected to the +48V power supply, and the hydraulic cylinder starts retracting.
