Technical Field

[0001] This invention relates to the field of elevator technology, specifically to an elevator fire emergency response and alarm system. Background Technology

[0002] To change the traditional elevator supervision model, improve the quality of elevator maintenance, enhance elevator management, reduce elevator malfunctions, and ensure the safety of people's travel, it is recommended to build an elevator safety Internet of Things platform.

[0003] With the increasing frequency of elevator use and the passage of time, the safety situation remains serious, and elevators have become one of the common places that pose safety hazards to citizens' travel.

[0004] Existing elevators typically only issue alarms in the event of a fire, lacking the ability to extinguish the fire themselves. This results in fires not being extinguished promptly, and given the limited space inside elevators, the inability to extinguish fires quickly can easily cause irreversible harm to users. To enable elevators to extinguish fires in advance and reduce harm to users, the inventors have developed an elevator fire emergency response and alarm system. Summary of the Invention

[0039] Example 1

[0040] Please see Figure 1-2 An emergency fire response and alarm system for elevator 1 is disclosed, applied within a vertically moving elevator 1, wherein the elevator 1 moves up and down within a corresponding elevator shaft. The system includes a smoke detector 11, a sprinkler mechanism, and a liquid storage mechanism. The smoke detector 11 is installed on the inner wall of the elevator 1. The sprinkler mechanism is located inside the elevator 1. The liquid storage mechanism includes a storage tank 2 located at the upper end of the elevator 1, storing fire extinguishing agent. A fire extinguishing pipe 21 for delivering the fire extinguishing agent to the sprinkler mechanism is provided on one side of the storage tank 2. The storage tank 2 also includes a first delivery mechanism for delivering the fire extinguishing agent to the sprinkler mechanism at a certain pressure. The smoke detector 11 is designed to promptly detect the occurrence of a fire inside the elevator 1 using a sensor. The smoke is then transmitted to the control system, which promptly issues an alarm. The control system then controls the liquid storage mechanism and the sprinkler mechanism to promptly spray and extinguish the fire inside the elevator 1, thus achieving emergency response to a fire in the elevator 1, enabling timely fire extinguishing and alarm activation.

[0041] In this embodiment, please refer to Figure 5 The first conveying mechanism includes a first conveying plate 23 and a first spring 24. The first conveying plate 23 is slidably and sealingly connected inside the liquid storage tank 2. The first spring 24 is located inside the liquid storage tank 2 and is used to drive the first conveying plate 23 to move automatically toward the fire extinguishing pipe 21. The fire extinguishing pipe 21 is equipped with a solenoid valve for controlling its opening and closing. The design of the first spring 24 allows the fire extinguishing agent to be stored in the liquid storage tank 2 at a certain pressure using the elasticity of the spring. When fire extinguishing is required, simply opening the solenoid valve on the fire extinguishing pipe 21 allows the fire extinguishing agent in the liquid storage tank 2 to be automatically delivered to the spraying mechanism at a certain pressure for spraying fire extinguishing. This design eliminates the need for additional power equipment, reducing costs and also reducing the increase in the overall weight of the elevator 1, thus reducing the load.

[0042] In this embodiment, please refer to Figure 1-2The spraying mechanism includes a spray box 14 and a spray pipe 10. The spray box 14 is fixedly installed on the inner wall of the elevator 1, and a retractable and rotatable first pipe 15 is provided in the middle of the spray box 14. The spray pipe 10 is vertically and evenly surrounding the outside of the first pipe 15. The extended end of the first pipe 15 is provided with a second pipe 17 that communicates with the spray pipe 10. Both the spray pipe 10 and the second pipe 17 are provided with a plurality of spray holes 16 for spraying fire extinguishing agent. The spray holes 16 are located on the same side of the spray pipe 10 and the second pipe 17 at an angle below. The spraying direction of the fire extinguishing agent is inclined downward. At the same time, the end of the fire extinguishing pipe 21 is connected to the first pipe 15. The first pipe 15 is circular and is composed of multiple pipe bodies with decreasing diameters that slide and are sealed together. One end of the first pipe 15 is provided with a sixth spring connected to it, and the other end of the sixth spring is movably connected to the other end of the first pipe 15. The design of the sprinkler pipe 10, the first pipe 15, the second pipe 17, and the nozzle 16 allows the water pressure during spraying to automatically extend the first pipe 15, enabling the sprinkler pipe 10 to move downwards automatically. The nozzle 16's position design allows the extinguishing agent to be sprayed at an angle downwards, ensuring even distribution. Furthermore, the reaction force from the nozzle 16 during spraying drives the sprinkler pipe 10 to rotate, achieving simultaneous downward movement and rotation of the extinguishing agent, resulting in more even distribution and improved extinguishing effectiveness. The design of the first spring 24 utilizes the elasticity of the sixth spring to allow the sprinkler pipe 10 to retract into the inner wall of the elevator 1 along with the retraction of the first pipe 15 after spraying stops, achieving overall concealment and reducing space occupation.

[0043] As one possible implementation method, please refer to Figure 3-4The first pipe 15 has a through-type extension end, and a detachable sealing pipe 154 for sealing the first pipe 15 is provided at the outlet of the extension end of the first pipe 15. A fire extinguishing hole 156 is provided on the side wall of the sealing pipe 154 located inside the first pipe 15. A corrugated hose 153 with a retractable length is provided inside the first pipe 15. One end of the corrugated hose 153 is connected to and fixedly connected to the sealing pipe 154, and the other end of the corrugated hose 153 is provided with a connecting pipe 152 that is detachably connected to the end of the corresponding first pipe 15. The connecting pipe 152 is connected to the fire extinguishing pipe 21. A pull ring 155 is fixedly connected on the outside of the sealing pipe 154. A protrusion 151 is provided on the outside of the connecting pipe 152 that engages and seals with the outlet of the extension end of the first pipe 15. When the protrusion 151 seals the outlet of the extension end of the first pipe 15, it also seals the inlet of the second pipe 17. The design of the corrugated hose 153, sealing tube 154, and connecting tube 152 allows for fire suppression when the sprinkler pipe 10 cannot extinguish the fire. Since the first tube 15 is in an extended state, the height of the pull ring 155 is manageable for ordinary people. Therefore, people inside the elevator 1 can pull the pull ring 155 to separate the sealing tube 154 and the connecting tube 152 from the first tube 15. By continuing to pull, the connecting tube 152 seals the outlet of the extended end of the first tube 15, and the side wall of the connecting tube 152 seals the inlet of the second tube 17. At this point, the extinguishing agent in the fire extinguishing tube 21 can be sprayed out only through the fire extinguishing hole 156. Users can then use the sealing tube 154 to extinguish the fire at the corresponding point of ignition. This design is disposable and requires manual replacement after use.

[0044] In this embodiment, the sixth spring is disposed outside the first tube 15, and one end of the sixth spring is rotatably connected to the inner wall of the hidden groove 141, while the other end of the sixth spring is movably connected to the second tube 17.

[0045] In this embodiment, please refer to Figure 6-7 and Figure 12The system also includes a replenishment tank 7 located at the bottom of elevator shaft 1. The replenishment tank 7 contains a storage tank 71 for storing the extinguishing agent. A delivery pipe 70 for delivering the extinguishing agent is located at the top of the replenishment tank 7, and a delivery pump 73 for delivering the extinguishing agent to the delivery pipe 70 is located on one side of the replenishment tank 7. A delivery trough 18 corresponding to the delivery pipe 70 is located at the bottom of elevator shaft 1. A first regulating valve that can be selectively opened is located within the delivery trough 18. A replenishment pipe 22 for replenishing the extinguishing agent is also located on the storage tank 2. The extension end of the replenishment pipe 22 passes through the interior of elevator shaft 1 and communicates with the delivery trough 18. The delivery pipe 70 contains a solenoid valve, and the bottom of the delivery trough 18 has a guide channel 181 in the shape of an outwardly diffusing cone. The delivery pipe 70 and the interior of the delivery trough 18 are slidably and sealingly connected. The first regulating valve is a solenoid valve. The design of the replenishment tank 7 allows for timely replenishment of extinguishing agent in the storage tank 2, achieving automatic replenishment. This automatic replenishment method effectively reduces the load on the overall weight of the elevator 1 while ensuring that the storage tank 2 always contains extinguishing agent. The design of the delivery pipe 70 and delivery trough 18 allows the delivery pipe 70 to be directly inserted into the delivery trough 18 through the guide trough 181 when the elevator 1 moves to the bottom of the elevator shaft. The delivery pipe 70 pushes the adjusting plate upward, causing it to move to the first connecting groove, thus connecting the delivery pipe 70 and the replenishment pipe 22. This allows the extinguishing agent to be delivered to the storage tank 2. By closing the solenoid valve on the extinguishing pipe 21, the extinguishing agent can be stored in the storage tank 2 at a certain pressure.

[0046] Example 2

[0047] The similarities to Example 1 will not be described again; the differences from Example 1 are as follows:

[0048] Please see Figure 5-6The extinguishing agent is tap water. The upper end of the elevator 1 is also equipped with a fixedly connected disinfection tank 3, which stores a high concentration of disinfectant. The output end of the disinfection tank 3 is connected to a disinfection pipe 32, which is connected to the fire extinguishing pipe 21. The disinfection tank 3 also has a second conveying mechanism for conveying the disinfectant at a certain pressure. The second conveying mechanism includes a second conveying plate 31 and a second spring 34. The second conveying plate 31 is slidably and sealed within the disinfection tank 3, and the second spring 34 is located within the disinfection tank 3 to drive the disinfectant to be squeezed and conveyed into the disinfection pipe 32. The disinfection pipe 32 is equipped with a solenoid valve for controlling its opening and closing. The design of using water as the extinguishing agent reduces the overall cost. At the same time, a disinfection tank 3 is installed on elevator 1 and connected to the fire extinguishing pipe 21 via a disinfection pipe 32. When disinfection is required, the solenoid valve on the disinfection pipe 32 is opened when the fire extinguishing pipe 21 is opened. This allows the disinfectant in the disinfection tank 3 to mix with tap water in a certain proportion and be sprayed out through the spray pipe 10, thereby achieving automatic disinfection of the interior of elevator 1. Moreover, the high-concentration disinfectant design effectively reduces the frequency of disinfectant addition.

[0049] In this embodiment, the disinfection box 3 is also provided with a liquid filling tube 33 for replenishing disinfectant, and the liquid filling tube 33 is provided with a detachable sealing plug for sealing.

[0050] Example 3

[0051] The similarities to Example 1 will not be described again; the differences from Example 1 are as follows:

[0052] Please see Figure 6 , Figure 8 The extinguishing agent is tap water. The replenishment tank 7 is also provided with a cleaning mechanism for cleaning the floor of elevator 1. The cleaning mechanism is set on the side wall of elevator 1 shaft. The side wall of elevator 1 shaft is provided with an adjustment mechanism for moving the cleaning mechanism into the elevator 1.

[0053] In this embodiment, please refer to Figure 8-9The adjustment mechanism includes a first electric push rod 5 and a second electric push rod 52. A storage groove 51 for recycling the cleaning plate 4 is provided on the inner wall of the elevator shaft 1. The first electric push rod 5 is rotatably connected within the storage groove 51, with its end fixedly connected to the middle of the cleaning plate 4. A second electric push rod 52, connected to and used to drive the first electric push rod 5 to rotate, is also provided within the storage groove 51. The extended end of the second electric push rod 52 is connected to the outer wall of the first electric push rod 5. The design of the first electric push rod 5 and the second electric push rod 52 enables the cleaning plate 4 to rotate on the inner wall of the elevator shaft 1, effectively reducing the depth of the storage groove 51, thereby reducing the degree of damage to the inner wall of the elevator shaft 1 and lowering the installation cost. The first electric push rod 5 enables the cleaning plate 4 to move back and forth inside the elevator shaft 1 for cleaning, allowing the cleaning plate 4 to more thoroughly clean the floor of the elevator shaft 1.

[0054] In this embodiment, please refer to Figure 12 The replenishment tank 7 also includes a cleaning tank 72 for storing cleaning agents. The inlet of the delivery pump 73 is connected to the cleaning tank 72 via a pipe. Both the cleaning tank 72 and the outlet pipes of the storage tank 71 are equipped with solenoid valves for controlling their opening and closing. The design of the cleaning tank 72 and the cleaning agent allows for the softening of stains on the inner wall of the elevator 1 by spraying cleaning agent onto the elevator 1, thus improving the cleaning effect. The cleaning agent can be sprayed first to soften the stains, followed by rinsing with tap water, effectively enhancing the overall cleaning result.

[0055] In this embodiment, please refer to Figure 8-10The cleaning mechanism includes a cleaning plate 4. The bottom of the cleaning plate 4 is fixedly connected to a first cleaning cotton layer 43 for cleaning the floor of the elevator 1. The cleaning plate 4 has multiple first cleaning holes 44 for spraying tap water. A first vertical pipe 62 is located in the middle of the upper end of the cleaning plate 4. A second vertical pipe 61 is slidably and sealed inside the first vertical pipe 62. Multiple vertically aligned and interconnected spray vertical pipes 6 are located outside the second vertical pipe 61. Multiple evenly distributed second cleaning cotton layers 44 are located diagonally above the same side of each spray vertical pipe 6. The first vertical pipe 62 has a fixedly connected annular plate 621 inside the washing hole 64. The annular plate 621 has a third vertical pipe in the middle. The third vertical pipe is connected to the second vertical pipe 61 and the annular plate 621 is connected by a reciprocating thread. The output end of the delivery pump 73 is provided with a cleaning pipe 74. The output end of the cleaning pipe 74 is connected to the first cleaning hole 44 and the second cleaning hole 64 respectively. The second vertical pipe 61 and the corresponding spray vertical pipe 6 are connected by a connecting horizontal pipe 63 for fixing the spray vertical pipe 6. The design of the first cleaning cotton layer 43 allows for better wiping and cleaning of the floor. The design of the first cleaning hole 44 allows the first cleaning cotton layer 43 to spray and clean simultaneously while wiping, further improving the cleaning effect. The rotating connection between the first vertical pipe 62 and the second vertical pipe 61, as well as the angle design of the second cleaning hole 64, allows the reaction force generated when the second cleaning hole 64 sprays to drive the spray vertical pipe 6 to rotate, and drive the second vertical pipe 61 to rotate within the first vertical pipe 62. The design of the third vertical pipe, the annular plate 621, and the reciprocating thread allows the second vertical pipe 61 to rotate while driving the third vertical pipe to rotate. In addition, the characteristics of the reciprocating thread allow the spray vertical pipe 6 to move up and down synchronously and periodically while rotating and spraying, thereby further increasing the spraying area of ​​the spray vertical pipe 6. This allows for a more thorough cleaning of the easily soiled areas in the lower half of the elevator 1, and the spraying and rinsing are more even.

[0056] In this embodiment, please refer to Figure 8-11 The first vertical tube 62 is rotatably mounted on the cleaning plate 4. The cleaning plate 4 has a storage slot 41 for automatic retraction of the first vertical tube 62 after rotation. The end of the first vertical tube 62 is rotatably connected to the storage slot 41 via a connecting shaft 412. The storage slot 41 contains a third electric push rod 411 for driving the first vertical tube 62 to rotate. The storage slot 41, located directly below the vertical first vertical tube 62, has a positioning slot 45 that communicates with the cleaning tube 74. The positioning slot 45 also contains a valve mechanism for selectively opening the positioning slot 45. Rotating the first vertical tube 62 effectively reduces the space required for the storage tank 51 and increases its length, thereby increasing the overall spraying area.

[0057] In this embodiment, please refer to Figure 11 The receiving groove 41, located outside the positioning groove 45, is provided with an annular groove 622 for engaging the bottom of the first vertical tube 62. A waterproof rubber gasket 624 for sealing and waterproofing is provided within the annular groove 622. This further improves the sealing performance of the connection.

[0058] As one possible implementation method, please refer to Figure 11 The valve mechanism can be a solenoid valve, or the valve mechanism includes a piston plate 455, a limiting groove 454, and a limiting block 452. The piston plate 455 is slidably and sealingly connected in the positioning groove 45. The positioning groove 45 has symmetrically distributed limiting grooves 454 on its side wall. The limiting groove 454 has a slidably and sealingly connected limiting block 452 in it. The limiting groove 454 also has a fourth spring 453 for automatically moving the limiting block 452 to the opening of the positioning groove 45. The inner wall of the positioning groove 45 also has a second connecting groove 451 for connecting the upper and lower ends of the piston plate 455. The center of the end of the first vertical tube 62 has a fixedly connected extrusion rod 623 for moving the piston plate 455 downward to the second connecting groove 451. The design of the extrusion rod 623 and piston plate 455 allows the extrusion rod 623 to press the piston plate 455 downwards to the second connecting groove 451 when the first vertical tube 62 rotates to a vertical position, thus connecting the positioning groove 45 with the first vertical tube 62. As the first vertical tube 62 rotates and retracts, the extrusion rod 623 separates from the piston plate 455. Due to the elasticity of the fourth spring 453, the piston plate 455 automatically seals the positioning groove 45, achieving automatic sealing of the positioning groove 45. Alternatively, a solenoid valve could be used for the valve mechanism. Compared to using a solenoid valve, this reduces the need for control logic and lowers costs.

[0059] In this embodiment, please refer to Figure 10 The first cleaning holes 44 are arranged in two rows and symmetrically on both sides of the first cotton layer. The cleaning plate 4 is provided with symmetrically distributed liquid inlet grooves 441. The first cleaning holes are respectively connected to the corresponding liquid inlet grooves 441. A series groove 442 is provided between adjacent liquid inlet grooves 441. The output end of the cleaning tube 74 is connected to one side of the corresponding liquid inlet groove 441. The series groove 442 is connected to the positioning groove 45.

[0060] As one possible implementation method, please refer to Figure 9The cleaning plate 4 has symmetrically distributed side plates 462 at both ends. Each side plate 462 is provided with an extension tube 463 that is fixedly connected to and corresponds to the cleaning tank 72.

The bottom of the side plate 462 is also provided with a fixedly connected second cleaning cotton layer 46. The second cleaning cotton layer 46 is slidably connected to the bottom of the cleaning plate 4. The bottom of the extension tube 463 is also provided with a first cleaning hole 44. Both sides of the cleaning plate 4 are provided with a fifth spring 461 that is fixedly connected to and used to drive the corresponding side plate 462 to automatically retract and adhere to both sides of the cleaning plate 4.

[0061] In this embodiment, please refer to Figure 1 and Figure 6 The elevator 1 has a ring-shaped sewage tank 12 on its ground. A sewage pipe 13 connected to the sewage tank 12 is located at the bottom of the elevator 1. A wastewater pipe is fixedly connected to the replenishment tank 7. The diameter of the wastewater pipe is larger than that of the sewage pipe 13, and the extended end of the wastewater pipe is connected to the domestic water discharge pipe near the elevator shaft. The design of the sewage tank 12 allows sewage to be promptly collected during cleaning and enters the wastewater pipe through the sewage pipe 13, thus entering the domestic sewage system for timely discharge. This prevents sewage from accumulating at the bottom of the elevator shaft. Furthermore, the sewage pipe 13 also improves airflow inside the elevator 1 to some extent.

[0062] This application discloses a fire emergency handling and alarm method for elevator 1, comprising the following steps:

[0063] (1) When the smoke alarm 11 senses a certain amount of smoke inside the elevator 1, the smoke alarm 11 transmits the signal to the control system, and then the control system alarms. At the same time, the control system opens the solenoid valve at the fire extinguishing pipe 21. The fire extinguishing agent in the storage tank 2 is pushed by the first conveying plate 23, enters the spraying mechanism through the fire extinguishing pipe 21, enters the second pipe 17 through the first pipe 15, and enters the spraying pipe 10. It is sprayed out through the spray hole 16 to extinguish the fire. Moreover, with the water pressure, the first pipe 15 can be automatically extended. At the same time, the reaction force generated by the spraying of the spray hole 16 pushes the spraying pipe 10 to rotate, thereby realizing the rotation spraying, so that the fire extinguishing agent can be more evenly distributed in the elevator 1. Automatic emergency fire extinguishing is achieved through spraying.

[0064] (2) When there are people in elevator 1, and the fire inside elevator 1 cannot be extinguished by the sprinkler pipe 10, the user can pull the pull ring 155 to separate the sealing pipe 154 and the connecting pipe 152 from the first pipe 15 respectively, and make the connecting pipe 152 seal the outlet of the first pipe 15 and the inlet of the second pipe 17. At this time, the user can hold one end of the sealing pipe 154 and aim the fire extinguishing hole 156 at the place that needs to be extinguished for direct fixed-point spraying fire extinguishing, which can extinguish the fire more effectively.

[0065] (3) When elevator 1 does not need to be extinguished, but needs to be cleaned and disinfected daily, the solenoid valve in the disinfection pipe 32 can be opened after the solenoid valve of the fire extinguishing pipe 21 is opened by the system control, so that the disinfectant is mixed with tap water in a certain proportion, and then the interior of elevator 1 is automatically sprayed and disinfected through the spraying mechanism.

[0066] (4) When cleaning elevator 1, the cleaning time can be set at midnight. The system controls elevator 1 to descend to the bottom of elevator shaft 1. When elevator 1 reaches the bottom, sewage pipe 13 is inserted into wastewater pipe and delivery pipe 70 is inserted into delivery trough 18. Delivery trough 18 is then sealed. Then, by controlling the solenoid valves on different pipes, tap water or cleaning agent is selectively introduced into cleaning plate 4 or spray mechanism. When a large cleaning or thorough cleaning is required, the door of elevator 1 is closed first, and then the fire extinguishing pipe is turned on. The solenoid valve inside 21 allows the tap water in the storage tank 2 to wet the inner wall of elevator 1. After the water in the storage tank 2 is used up, the delivery pump 73 uses the storage tank 2 to send the cleaning agent into the spraying mechanism, so that the cleaning agent is evenly spread inside elevator 1. After the spreading is completed, the door of elevator 1 is opened, and the cleaning plate 4 is rotated to the floor of elevator 1 by the second electric push rod 52. Then, the cleaning plate 4 is moved back and forth by the first electric push rod 5 to wipe the floor of elevator 1. At the same time, the solenoid valves of different pipelines are controlled to allow tap water to pass through. Pump 73 delivers water to the spray mechanism and cleaning plate 4. The spray mechanism sprays water at the top of elevator 1 for cleaning, while tap water entering the cleaning plate 4 is first sprayed out through the first cleaning hole 44 to rinse the floor of elevator 1. As the tap water increases, it drives the side plate 462 to move outward until it adheres to the inner wall of elevator 1, allowing the first cleaning cotton layer 43 and the second cleaning cotton layer 46 to thoroughly wipe and clean the floor of elevator 1. After the floor is wiped clean, the cleaning plate 4 is moved to the middle of elevator 1, and then the third electric motor is activated. The push rod 411 drives the first vertical tube 62 to a vertical position, while the extrusion rod 623 pushes the piston plate 455 downward, so that the first vertical tube 62 and the positioning groove 45 are connected. The water in the cleaning plate enters the first vertical tube 62 and is sprayed out through the second cleaning hole 64. The reaction force generated after the second cleaning hole 64 is sprayed out drives the spray vertical tube 6 to rotate, so that the spray vertical tube 6 can rotate and spray. At the same time, due to the reciprocating thread, the spray vertical tube 6 can move up and down synchronously in the vertical direction, which can thoroughly spray and clean the inner wall of the lower half of the elevator 1.The cleaning method for elevator 1 adopted in this application fully meets the cleaning requirements of elevator 1 under normal circumstances. Due to the constant flow of people, the floor is usually the dirtiest and the stains are the most difficult to remove. Therefore, the combination of the first cleaning cotton layer 43, the second cleaning cotton layer 46, and the first cleaning hole 44 can better and more thoroughly clean the floor of elevator 1. The lower half of elevator 1 is very close to the user's feet and is easily scratched by the soles of feet and also easily scratched by objects being moved. Therefore, the lower half of elevator 1 is a slightly dirtier area. Thus, the combination of the spraying mechanism and the spraying vertical pipe 6 can effectively clean the lower half area. At the same time, the upper half of the elevator 1 space is easily dirty, mainly consisting of dust. Therefore, only the spraying mechanism needs to spray the upper half of elevator 1. Different areas are cleaned with different intensities to effectively ensure the cleaning effect of elevator 1. When using elevator 1, different cleaning intensities can be selected according to the condition of elevator 1.
