Description

Technical Field

[0001] The present invention belongs to the technical field of safety protection of household elevators, and in particular relates to an intelligent safety device and a remote safety system for household villa elevators. Background Art

[0002] Villa elevators are elevators installed in private homes for use by a single family member only. They can also be installed in buildings that are not used by a single family as a tool for a single family to enter their residence, but the public or other residents in the building cannot enter or use them. For safety during use, villa elevators will be equipped with intelligent safety devices and safety systems to ensure the safety of elevator operation.

[0003] Villa elevators bring convenience to families. Since the elevators in villas are installed later, the space for elevator installation is limited. Screw elevators take up less space when installed, so screw elevators are usually the first choice when installing elevators in villas. Although screw elevators can be installed without a pit, in order to ensure the stability of the elevator after installation and to provide safety protection in the event of a fall, a pit will be set up.

[0004] Due to the existence of the pit, water may enter the pit. When a large amount of water enters the pit and the pit is flooded, the elevator safety protection action will cause the elevator to lose power, thereby causing the elevator to stop operating urgently. There is a possibility that people will be trapped in the car, and the water in the pit will pose a safety threat to the passengers and the car. At the same time, due to the particularity of villa construction, villas located in low terrain may be flooded when a flood disaster occurs. If people are in the villa, the emergency braking of the elevator will trap people in the car, posing a great threat to their safety. In addition, due to the power outage of the elevator, the lighting in the elevator shaft and the car will be turned off, which is not conducive to the escape of trapped people.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent safety device and a remote safety system for a home villa elevator, which can solve the problem that people cannot escape after the villa elevator stops suddenly due to a large amount of water in the pit or a flood disaster, and the problem that emergency lighting cannot be used due to power outages, making it inconvenient for people to escape.

[0007] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:

[0008] An intelligent safety device for a home villa elevator, comprising:

[0009] The elevator body includes an elevator shaft and an elevator car, and the elevator car is installed in the elevator shaft in a movable manner so as to transport people and objects through the movement of the elevator car. A first driving component is installed on the rear side wall of the elevator car, and the elevator car can be driven up and down in the elevator shaft by the first driving component.

[0010] The emergency drive assembly includes a mounting tube, wherein the mounting tube is fixedly connected to the lower end of the rear side wall of the elevator car, so that the mounting tube can be driven to move when the elevator car moves, and the bottom of the mounting tube is flush with the elevator car. At the same time, the upper end of the mounting tube is set to be closed, and the lower end of the mounting tube is set to be open. The mounting tube is provided with an inner shell in an integrated manner, and a receiving chamber is formed between the inner side wall of the mounting tube and the outer side wall of the inner shell, and the receiving chamber is filled with a reaction medium. The mounting tube is provided with an inner shell to form a receiving chamber for filling the reaction medium, so that the reaction medium is stored in the mounting tube. A plurality of first through holes are opened near the bottom of the side wall of the inner shell. When a large amount of water enters the elevator shaft and causes the bottom of the elevator car to contact with water, the bottom of the mounting tube can be contacted with water. Due to the opening of the mounting tube, water can enter the inner shell, so that water can enter the receiving chamber through the first through hole, so that the reaction medium contacts the water, and the reaction medium can react chemically with the water to produce a large amount of gas. A plurality of vents are provided on the side wall of the inner shell, and the gas generated by the reaction of the reaction medium in the accommodating chamber is discharged into the inner shell through the vents. A second drive assembly is installed on the top wall plate of the mounting tube, and the second drive assembly and the first drive assembly are connected to each other. A large amount of gas generated by the reaction of the reaction medium is used to drive the second drive assembly to rotate, thereby driving the first drive assembly to rotate through the rotation of the second drive assembly. When a large amount of water enters the pit and causes the pit to be flooded, or a flood disaster causes the villa to be flooded, the elevator will be shut down urgently, and if there are people in the elevator, they will be trapped. Therefore, in order to allow the elevator to rise to the top floor through emergency drive after an emergency stop, when a large amount of water enters the elevator shaft and the water in the elevator shaft contacts the bottom of the elevator car, water will enter through the bottom of the mounting tube, so that the water enters the accommodating chamber through the first through hole and contacts the reaction medium. When the reaction medium contacts water, a large amount of gas will be generated by reaction. After the gas is discharged through the air outlet, the second drive component will be driven to rotate, so that the first drive component can be driven to rotate through the rotation of the second drive component, so that the first drive component drives the elevator car to move upward to the top floor, so that people can escape through the top floor.

[0011] A daylighting lighting assembly includes a daylight collector, which is used to collect external natural light sources. In order to improve the daylight collector's efficiency in collecting external light sources, the daylight collector is set to a polygonal sphere, and the daylight collector uses a transparent daylighting material. The daylight collector is installed at the top of the elevator shaft, and a first pipe is installed on the inner wall of the top wall panel of the elevator shaft. The daylight collector and the first pipe are connected, so that the daylight collector installed at the top of the elevator shaft collects the light source and transmits it to the first pipe, and then transports it to the elevator shaft through the first pipe for use, so that the elevator shaft and the elevator car can be illuminated by natural light, and energy consumption can be saved while providing emergency lighting by natural light sources in the event of a power outage, so as to facilitate the escape of trapped people. Since different villas use different methods for installing elevators, if the top of the elevator shaft is set outside the villa roof, the light collector can be installed on the top of the elevator shaft. If the top of the elevator shaft is set inside the villa roof, then in order to realize the light collector to collect external light sources, the light collector is installed on the roof and connected to the elevator shaft through the first pipe.

[0012] In one or more embodiments of the present invention, the first driving assembly includes a screw and a driving motor, the screw is fixedly mounted in the elevator shaft, the driving motor is fixedly mounted on the rear side wall of the elevator car, a driving shaft is mounted on the driving end of the driving motor, a threaded sleeve is threadedly connected to the driving motor, and a driving chain is mounted on the driving shaft and the threaded sleeve. The driving motor drives the driving shaft to rotate, the driving shaft drives the driving chain to rotate when the driving shaft rotates, the driving chain drives the threaded sleeve to rotate, and the threaded sleeve can move up and down when it rotates on the screw, so that the elevator car can be driven to move up and down in the elevator shaft through the movement of the threaded sleeve.

[0013] In one or more embodiments of the present invention, the reaction medium adopts magnesium-based solid hydrogen storage material, which can react with water to produce a large amount of hydrogen. Therefore, when a large amount of water enters the pit or a flood disaster occurs, the water in the elevator shaft enters through the lower end of the installation tube and contacts the magnesium-based solid hydrogen storage material, which can cause the magnesium-based solid hydrogen storage material to decompose and produce a large amount of hydrogen. The hydrogen is released into the inner shell through the vent hole, and the second drive assembly can be powered by hydrogen to rotate the second drive assembly. Since hydrogen has the potential energy of moving upward, the power of the gas to the second drive assembly can be increased. The magnesium-based solid hydrogen storage material is set in powder form to increase the amount of reaction medium added to ensure that sufficient hydrogen can be provided to drive the rotation of the second drive assembly. At the same time, it should be noted that since hydrogen has the risk of explosion, when a large amount of hydrogen is discharged, safety protection measures should be set so that when hydrogen is discharged from the installation tube into the elevator shaft, it can be diluted using the space in the elevator shaft to eliminate the risk and ensure safety in use.

[0014] In one or more embodiments of the present invention, the gas outlet is arranged above the first through hole, so that the water at the bottom contacts the reaction medium through the first through hole, so that the gas generated by the decomposition of the reaction medium is discharged through the gas outlet. A boost deflector is installed on the inner side wall of the inner shell, and a limiting flow plate is fixedly connected to the inner side wall of the inner shell. The boost deflector is arranged above the gas outlet, and the boost deflector is used to guide and pressurize the gas discharged from the gas outlet to increase the rate of gas upward flow, and at the same time guide the gas when it flows upward, so that the gas acts on the second drive assembly to drive the rotation of the second drive assembly. The limiting flow plate is arranged between the first through hole and the gas outlet, so that the gas discharged from the gas outlet can only flow upward after being pressurized and guided by the boost deflector through the limiting flow plate.

[0015] In one or more embodiments of the present invention, the second drive assembly includes a rotating shaft, and the rotating shaft is rotatably connected to the top of the mounting tube, so that the rotating shaft can rotate when installed on the mounting tube. A bearing is installed on the top wall plate of the mounting tube, and the rotating shaft is installed on the bearing. Under the action of the bearing, the rotating shaft is installed on the mounting tube and can rotate. The lower end of the rotating shaft is placed in the mounting tube, and the upper end of the rotating shaft is placed on the outside of the mounting tube. A plurality of propeller blades are fixedly connected to the side wall of the lower end of the rotating shaft. The gas that is pressurized and diverted by the booster deflector will act on the propeller blades so that the propeller blades are subjected to force, thereby driving the propeller blades to rotate, and then driving the rotating shaft to rotate through the rotation of the propeller blades. A connecting shaft is installed at the lower end of the shaft of the driving motor, and a connecting rod is installed between the upper end of the rotating shaft and the lower end of the connecting shaft. When the rotating shaft rotates, the connecting shaft can be driven to rotate under the action of the connecting rod, and the rotation of the connecting shaft drives the shaft of the driving motor to rotate. The shaft of the driving motor can drive the driving shaft to rotate, thereby driving the threaded sleeve to rotate, and then the gas acts on the propeller blades and drives the propeller blades to rotate, thereby driving the elevator car to move in the elevator shaft.

[0016] In one or more embodiments of the present invention, the boost deflector guides the flow direction of the gas while pressurizing the gas, and the gas guided by the boost deflector acts on the propeller blades and drives the propeller blades to rotate, and the direction in which the gas guided by the boost deflector drives the propeller blades to rotate is the same as the direction in which the drive motor drives the elevator car to rise. In order to ensure that when the elevator is shut down and cannot operate due to a flood, the elevator can rise to the top floor, so that people trapped in the elevator car are at a high place, creating opportunities for people to escape, so when the propeller blades are driven to rotate, it is necessary to drive the elevator car to move upward, and when the propeller blades drive the drive motor to rotate, the rotation direction of the drive motor should be the rotation direction when the elevator car is driven to rise. Therefore, after the boost deflector pressurizes and guides the gas discharged from the air outlet, when the gas acts on the propeller blades, the direction in which the propeller blades rotate will be consistent with the opposite direction of the rotation when the drive motor drives the elevator car to rise.

[0017] In one or more embodiments of the present invention, a plurality of exhaust holes are provided on the top wall plate of the mounting tube, through which the gas acting on the propeller blades is discharged. Since the gas is hydrogen generated by magnesium-based solid hydrogen storage materials, the hydrogen can be discharged through the exhaust holes. Filters are installed on the plurality of exhaust holes, and the filters prevent external impurities from entering the exhaust holes, thereby ensuring the smooth flow of the exhaust holes. A feeding port is installed on the mounting tube, and the feeding port is connected to the accommodating chamber between the mounting tube and the inner shell, so that the reaction medium can be added to the solute chamber through the feeding port. A snap-on cover is installed at the bottom of the accommodating chamber. When the reaction medium in the solute chamber is decomposed, the remaining residue can be discharged by opening the snap-on cover, so that the reaction medium can be added again, so as to ensure subsequent emergency use.

[0018] In one or more embodiments of the present invention, a desiccant box is installed near the bottom of the inner side wall of the inner shell, and the desiccant box is filled with desiccant. A second through hole is provided on both side walls of the desiccant box, and the second through hole corresponds to the position of the first through hole. Since the reaction medium will decompose when it encounters water, in order to ensure the activity of the reaction medium, the reaction medium should be ensured to be in a dry state during normal use. Therefore, a desiccant box is provided so that the moisture in the air will be dried by the desiccant in the desiccant box, thereby avoiding the contact between the moisture in the air and the reaction medium. Only when a large amount of water enters the elevator shaft and the water enters the installation tube, the desiccant will not be able to prevent the water from contacting the reaction medium, so that when the installation tube is flooded with water, the water will decompose the reaction medium, causing the reaction medium to produce gas. At the same time, a desiccant box is provided, so that a large amount of water is absorbed. The gas generated by the decomposition of the reaction medium will be blocked by the desiccant to ensure that the decomposed gas is discharged through the air outlet. Even if a small amount of gas passes through the desiccant and is discharged, the position of the air outlet is set at a low level to ensure that most of the gas is discharged through the air outlet after the reaction medium in the solute chamber is decomposed, so that the gas acts on the propeller blades.

[0019] In one or more embodiments of the present invention, a second pipe is provided on the side wall of the first pipe, and the second pipe is provided along the inner side wall of the elevator shaft from one end away from the first pipe to the bottom of the elevator shaft, so that the light source in the first pipe can be transported to the bottom of the elevator shaft through the second pipe, thereby realizing the illumination of the entire elevator shaft. High-reflectivity coatings are provided on the inner side walls of the first pipe and the second pipe, and by providing high-reflectivity coatings in the first pipe and the second pipe, the light source collected by the light collector can be transported in the first pipe and the second pipe. Illuminating devices are provided on the first pipe and the second pipe, and the collected light source is converted into lighting use through the lighting devices.

[0020] A household villa elevator intelligent remote safety system, the intelligent remote safety system is used for the household villa elevator intelligent safety device.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The present invention is provided with an emergency drive assembly. When a large amount of water enters the elevator shaft or a flood occurs, causing the villa to be flooded, the water level in the elevator shaft rises, causing the water to contact the bottom of the elevator car, which will cause the reaction medium arranged in the installation tube to contact the water. The reaction medium will decompose to produce a large amount of gas to drive the second drive assembly to rotate, thereby driving the first drive assembly to drive the elevator car to rise to the top floor, so that the trapped people in the elevator car are at a high place, ensuring the safety of the people;

[0023] 2. The emergency drive assembly provided by the present invention can drive the elevator car to the top floor through the gas generated by the reaction between water and the reaction medium when the elevator power is interrupted, thus solving the problem that the elevator cannot move due to flood disasters and a large amount of water in the elevator shaft; at the same time, the reaction medium can be stored for a long time to ensure that it is not deactivated, so that the reliability of the device is high when it is used, and it has good promotion value;

[0024] 3. The present invention is provided with a lighting assembly, which collects external light sources through a light collector for elevator lighting. While saving energy consumption, when the elevator power is interrupted, it can ensure that there is emergency lighting provided by natural light sources in the elevator to facilitate the escape of trapped people, which has great promotion significance.

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] like Figure 1 to Figure 4 As shown, an intelligent safety device for a household villa elevator in one embodiment of the present invention includes an elevator body 1, an emergency drive component 2 and a lighting component 3.

[0038] like Figure 1 to Figure 4 As shown, the elevator body 1 includes an elevator shaft 11 and an elevator car 12. The elevator car 12 is installed in the elevator shaft 11 in a movable manner so as to transport people and objects through the movement of the elevator car 12. A first driving component is installed on the rear side wall of the elevator car 12, and the elevator car 12 can be driven up and down in the elevator shaft 11 by the first driving component.

[0039] like Figure 3 and Figure 4As shown, the first driving assembly includes a screw rod 13 and a driving motor 14, the screw rod 13 is fixedly installed in the elevator shaft 11, the driving motor 14 is fixedly installed on the rear side wall of the elevator car 12, the driving end of the driving motor 14 is installed with a driving shaft 15, a threaded sleeve rod 16 is threadedly connected to the driving motor 14, and a driving chain 17 is installed on the driving shaft 15 and the threaded sleeve rod 16. The driving motor 14 drives the driving shaft 15 to rotate, and the driving shaft 15 drives the driving chain 17 to rotate when the driving shaft 15 rotates, and the rotation of the driving chain 17 drives the threaded sleeve rod 16 to rotate, and the threaded sleeve rod 16 can move up and down when it rotates on the screw rod 13, so that the elevator car 12 can be driven to move up and down in the elevator shaft 11 through the movement of the threaded sleeve rod 16.

[0040] like Figure 3 to Figure 7As shown, the emergency drive assembly 2 includes a mounting tube 21, which is fixedly connected to the lower end of the rear side wall of the elevator car 12, so that when the elevator car 12 moves, the mounting tube 21 can be driven to move, and the bottom of the mounting tube 21 is flush with the bottom of the elevator car 12. At the same time, the upper end of the mounting tube 21 is set to be closed, and the lower end of the mounting tube 21 is set to be open. An inner shell 22 is arranged in the mounting tube 21 by an integral molding method, and an accommodating chamber is formed between the inner side wall of the mounting tube 21 and the outer side wall of the inner shell 22, and the accommodating chamber is filled with a reaction medium 23. The inner shell 22 is arranged in the mounting tube 21, thereby forming a accommodating chamber for filling the reaction medium 23, so that the reaction medium 23 is stored in the mounting tube 21. A plurality of first through holes 24 are provided near the bottom of the side wall of the inner shell 22. When a large amount of water enters the elevator shaft 11, causing the bottom of the elevator car 12 to contact the water, the bottom of the installation tube 21 can be made to contact the water. Since the bottom of the installation tube 21 is set as an opening, water can enter the inner shell 22, so that the water can enter the accommodating chamber through the first through hole 24, so that the reaction medium 23 can contact the water, and the reaction medium 23 can react chemically with the water to produce a large amount of gas. A plurality of air outlets 25 are provided on the side wall of the inner shell 22, and the gas generated by the reaction of the reaction medium 23 in the accommodating chamber will be discharged into the inner shell 22 through the air outlet 25. A second drive assembly is installed on the top wall plate of the installation tube 21, and the second drive assembly and the first drive assembly are connected to each other. A large amount of gas generated by the reaction of the reaction medium 23 is used to drive the second drive assembly to rotate, thereby driving the first drive assembly to rotate through the rotation of the second drive assembly. When a large amount of water enters the pit and causes the pit to be flooded, or when a flood disaster occurs and causes the villa to be flooded, the elevator will be shut down in an emergency, and if there are people in the elevator, they will be trapped. Therefore, in order to allow the elevator to rise to the top floor through emergency drive after the emergency shutdown, when a large amount of water enters the elevator shaft 11 and the water in the elevator shaft 11 contacts the bottom of the elevator car 12, water will enter through the bottom of the mounting tube 21, so that the water enters the accommodating chamber through the first through hole 24 and contacts the reaction medium 23. When the reaction medium 23 contacts the water, a large amount of gas will be generated by reaction. After the gas is discharged through the gas outlet 25, the second drive assembly will be driven to rotate, so that the rotation of the second drive assembly can drive the first drive assembly to rotate, so that the first drive assembly drives the elevator car 12 to move upward to the top floor, so that when people are trapped in the elevator in a flood, they will be on the top floor of the villa, and they can escape through the top floor.

[0041] Preferably, the reaction medium 23 uses a magnesium-based solid hydrogen storage material, which can react with water to produce a large amount of hydrogen. Therefore, when a large amount of water enters the pit or a flood disaster occurs, the water in the elevator shaft 11 enters through the lower end of the installation tube 21 and contacts the magnesium-based solid hydrogen storage material, so that the magnesium-based solid hydrogen storage material can be decomposed to produce a large amount of hydrogen. The hydrogen is released into the inner shell 22 through the air outlet 25, and the second drive assembly can be powered by hydrogen to rotate the second drive assembly. Since hydrogen has the potential energy of moving upward, the power of the gas to the second drive assembly can be increased. The magnesium-based solid hydrogen storage material is set in a powdered state to increase the amount of reaction medium 23 added to ensure that sufficient hydrogen can be provided to drive the rotation of the second drive assembly. At the same time, it should be noted that since hydrogen has the risk of explosion, when a large amount of hydrogen is discharged, safety protection measures should be set so that when hydrogen is discharged from the installation tube 21 into the elevator shaft 11, it can be diluted using the space in the elevator shaft 11 to eliminate the risk and ensure safety in use.

[0042] like Figure 6 and Figure 7 As shown, the gas outlet 25 is arranged above the first through hole 24, so that the water at the bottom contacts the reaction medium 23 through the first through hole 24, and the gas generated by the decomposition of the reaction medium 23 is discharged through the gas outlet 25. A booster deflector 26 is installed on the inner side wall of the inner shell 22, and a limiting plate 27 is fixedly connected to the inner side wall of the inner shell 22. The booster deflector 26 is arranged above the gas outlet 25. The booster deflector 26 is used to guide and pressurize the gas discharged from the gas outlet 25, so as to increase the gas upward flow rate, and guide the gas when it flows upward, so that the gas acts on the second drive assembly to drive the rotation of the second drive assembly. The limiting plate 27 is arranged between the first through hole 24 and the gas outlet 25, so that the gas discharged from the gas outlet 25 can only flow upward after being pressurized and guided by the booster deflector 26 through the limiting plate 27.

[0043] like Figures 4 to 7As shown, the second driving assembly includes a rotating shaft 28, which is rotatably connected to the top of the mounting cylinder 21, so that the rotating shaft 28 can rotate when installed on the mounting cylinder 21. A bearing 210 is installed on the top wall plate of the mounting cylinder 21, and the rotating shaft 28 is installed on the bearing 210. Under the action of the bearing 210, the rotating shaft 28 can rotate when installed on the mounting cylinder 21. The lower end of the rotating shaft 28 is placed in the mounting cylinder 21, and the upper end of the rotating shaft 28 is placed outside the mounting cylinder 21. A plurality of propeller blades 29 are fixedly connected to the side wall of the lower end of the rotating shaft 28. The gas that is pressurized and diverted by the booster deflector 26 will act on the propeller blades 29, so that the propeller blades 29 are subjected to force, thereby driving the propeller blades 29 to rotate, and then the rotation of the propeller blades 29 drives the rotating shaft 28 to rotate. A connecting shaft 211 is installed at the lower end of the shaft of the driving motor 14, and a connecting rod 212 is installed between the upper end of the rotating shaft 28 and the lower end of the connecting shaft 211. When the rotating shaft 28 rotates, the connecting shaft 211 can be driven to rotate under the action of the connecting rod 212. The rotation of the connecting shaft 211 drives the shaft of the driving motor 14 to rotate, and the shaft of the driving motor 14 can drive the driving shaft 15 to rotate, thereby driving the threaded sleeve 16 to rotate, and then the gas acts on the propeller blades 29 and drives the propeller blades 29 to rotate, thereby driving the elevator car 12 to move in the elevator shaft 11.

[0044] Specifically, the boost deflector 26 guides the flow of the gas while boosting the gas. The gas guided by the boost deflector 26 acts on the propeller blades 29 and drives the propeller blades 29 to rotate. The direction in which the gas guided by the boost deflector 26 drives the propeller blades 29 to rotate is the same as the direction in which the drive motor 14 drives the elevator car 12 to rise. In order to ensure that when the elevator is shut down and cannot operate due to a flood, the elevator can rise to the top floor, so that people trapped in the elevator car 12 are at a high place, creating opportunities for people to escape. Therefore, when the propeller blades 29 are driven to rotate, it is necessary to drive the elevator car 12 to move upward. When the propeller blades 29 drive the drive motor 14 to rotate, the rotation direction of the drive motor 14 should be the rotation direction when the elevator car 12 is driven to rise. Therefore, after the booster deflector 26 boosts the pressure and guides the gas discharged from the air outlet 25, when the gas acts on the propeller blades 29, the propeller blades 29 will rotate in the opposite direction to the rotation direction when the drive motor 14 drives the elevator car 12 to rise.

[0045] like Figure 7As shown, a plurality of exhaust holes 213 are provided on the top wall plate of the mounting tube 21, through which the gas acting on the propeller blades 29 is discharged. Since the gas is hydrogen generated by the magnesium-based solid hydrogen storage material, the hydrogen can be discharged through the exhaust holes 213. A filter screen 214 is installed on each of the plurality of exhaust holes 213, through which the filter screen 214 prevents external impurities from entering the exhaust holes 213, thereby ensuring the unblocking of the exhaust holes 213. A feed port 215 is installed on the mounting tube 21, and the feed port 215 is connected to the accommodating chamber between the mounting tube 21 and the inner shell 22, so that the reaction medium 23 can be added to the solute chamber through the feed port 215. A snap-on cover 216 is installed at the bottom of the accommodating chamber, and when the reaction medium 23 in the solute chamber is decomposed, the remaining residue can be discharged by opening the snap-on cover 216, so that the reaction medium 23 can be added again, so as to ensure the subsequent emergency use.

[0046] like Figures 5 to 8 As shown, a desiccant box 217 is installed near the bottom of the inner wall of the inner shell 22, and a desiccant 218 is filled in the desiccant box 217. Second through holes 219 are provided on both side walls of the desiccant box 217, and the second through holes 219 correspond to the positions of the first through holes 24. Since the reaction medium 23 will decompose when it meets water, in order to ensure the activity of the reaction medium 23, the reaction medium 23 should be kept in a dry state during normal use. Therefore, a desiccant box 217 is provided so that the moisture in the air can be dried by the desiccant 218 in the desiccant box 217, thereby avoiding the moisture in the air from contacting the reaction medium 23. Only when a large amount of water enters the elevator shaft 11, so that the water enters the installation tube 21, the desiccant 218 cannot prevent the water from contacting the reaction medium 23, so that when the installation tube 21 is flooded, the water can decompose the reaction medium 23, so that the reaction medium 23 produces gas. Meanwhile, a desiccant box 217 is provided to absorb a large amount of water. The gas generated by the decomposition of the reaction medium 23 will be blocked by the desiccant 218 to ensure that the decomposed gas is discharged through the air outlet 25. Even if a small amount of gas passes through the desiccant 218 and is discharged, the position of the air outlet 25 is set at a relatively low position to ensure that most of the gas is discharged through the air outlet 25 after the reaction medium 23 in the solute chamber is decomposed, so that the gas acts on the propeller blade 29.

[0047] Under normal conditions, the operation of the drive motor 14 drives the elevator car 12 to move up and down, so the drive motor 14 will switch between forward and reverse rotation, so that the rotating shaft 28 drives the propeller blades 29 to rotate forward and reversely. When the propeller blades 29 rotate forward and reversely, they will drive the gas inside the inner shell 22 to flow, so that the inner shell 22 is in a dry state, so as to prevent moisture from contacting the reaction medium 23 through the air outlet 25, thereby ensuring that the reaction medium 23 can be stored for a long time and still ensure that it will not be deactivated.

[0048] like Figure 1 As shown, the lighting assembly 3 includes a light collector 31, which is used to collect external natural light sources. In order to improve the collection efficiency of the light collector 31 for external light sources, the light collector 31 is set to a polygonal sphere, and the light collector 31 uses a transparent lighting material. The light collector 31 is installed on the top of the elevator shaft 11, and a first pipe 32 is installed on the inner wall of the top wall plate of the elevator shaft 11. The light collector 31 and the first pipe 32 are connected, so that the light collector 31 installed on the top of the elevator shaft 11 collects the light source and transmits it to the first pipe 32, and then transports it to the elevator shaft 11 through the first pipe 32 for use, so that the elevator shaft 11 and the elevator car 12 can be illuminated by natural light, and energy consumption can be saved while providing emergency lighting by natural light sources in the event of power failure, so as to facilitate the escape of trapped people. Since different villas use different methods for installing elevators, if the top of the elevator shaft 11 is set outside the roof of the villa, the light collector 31 can be installed on the top of the elevator shaft 11. If the top of the elevator shaft 11 is set inside the roof of the villa, in order to realize the collection of external light sources by the light collector 31, the light collector 31 is installed on the roof and connected to the elevator shaft 11 through the first pipe 32.

[0049] like Figure 1 As shown, a second pipe 33 is arranged on the side wall of the first pipe 32, and one end of the second pipe 33 away from the first pipe 32 is arranged along the inner wall of the elevator shaft 11 toward the bottom of the elevator shaft 11, so that the light source in the first pipe 32 can be transported to the bottom of the elevator shaft 11 through the second pipe 33, so as to realize the illumination of the entire elevator shaft 11. High reflectivity coatings are arranged on the inner walls of the first pipe 32 and the second pipe 33. By arranging high reflectivity coatings in the first pipe 32 and the second pipe 33, the light source collected by the light collector 31 can be transported in the first pipe 32 and the second pipe 33. Illuminating devices 34 are arranged on the first pipe 32 and the second pipe 33, and the collected light source is converted into lighting use by the lighting device 34.

[0050] During use, when a flood disaster or anomaly causes a large amount of water to enter the elevator shaft 11, causing the elevator system to be powered off and shut down urgently, when the water in the elevator shaft 11 contacts the bottom of the elevator car 12, the water enters the inner shell 22 through the bottom of the installation tube 21, and then the water enters the desiccant box 217 through the second through hole 219, so that the desiccant 218 absorbs a large amount of water, and the water enters the solute chamber between the installation tube 21 and the inner shell 22 through the first through hole 24 and contacts the reaction medium 23, and the reaction medium 23 decomposes to produce a large amount of gas, which is discharged through the outlet hole 25, and then acts on the propeller blade 29 after being pressurized and guided by the booster guide 26, so that the propeller blade 29 carries The movable rotating shaft 28 rotates in the direction of rotation when the driving motor 14 drives the elevator car 12 to rise. The rotation of the rotating shaft 28 will drive the shaft of the driving motor 14 to rotate, and the shaft of the driving motor 14 will drive the driving shaft 15 to rotate. The rotation of the driving shaft 15 drives the driving chain 17 to rotate. The rotation of the driving chain 17 drives the threaded sleeve 16 to rotate on the screw 13, so that the elevator car 12 moves upward. When the elevator car 12 moves to the top floor, it will stop moving under the action of the limit device, so that the elevator car 12 is at the top floor position, so that the people trapped in the elevator car 12 are at a high place in the villa, avoiding the water in the elevator shaft 11 to cause a safety threat to the people in the elevator car 12.
