Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a stealthy intelligent elevator used in the renovation of old residential communities. Background Technology

[0002] In the process of urbanization, the problems of old residential communities are becoming increasingly prominent. These communities are mostly multi-story buildings. With the increasing trend of social aging, elevators have become an important constraint on the travel of the elderly. In order to solve the travel problems of the elderly, improve their quality of life, and meet the travel requirements of residents in old residential communities, elevators have begun to be installed in multi-story buildings in old residential communities.

[0003] However, many contradictions and problems have arisen in the current process of elevator installation, mainly in the following aspects: 1) Because elevator installation requires the construction of elevator shafts outside the original building, which requires a certain amount of ground area. Generally speaking, the distance between the original buildings in old communities is not very large, and the area occupied by the newly built elevator shaft is large, which may even affect the fire lane and cause fire safety hazards; 2) The huge elevator shaft will affect the lighting and ventilation of the original building; 3) The cost of adding elevators is considerable, which increases the investment and living burden of residents, and the elevator shaft accounts for a large proportion of the cost.

[0004] Therefore, this utility model proposes a new type of elevator that can bring convenience to residents' lives by adding elevators and can overcome the above-mentioned shortcomings and problems in the process of adding elevators. This utility model is proposed in this context. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent, concealed elevator for the renovation of old residential communities. The elevator utilizes "concealment" technology, eliminating the need for elevator shafts built outside the building. This improvement not only avoids conflicts and disputes caused by the floor space occupied by elevator shafts, but more importantly, the chimney effect of traditional elevator shafts can cause fires inside the shaft to become extremely fierce, damaging the elevator car and its electronic components, leading to a sudden stop and potentially trapping people inside between floors, making rescue difficult and endangering their lives. Therefore, fire safety regulations stipulate that in the event of a fire, elevators should automatically descend to the first floor, the doors should automatically open, and the elevator should stop operating; elevators should not be used as escape routes. Thus, this utility model's "concealed" elevator lays the foundation for using elevators for escape in the event of a fire. Furthermore, by eliminating the traditional elevator shaft, it greatly reduces the impact on the existing building's lighting and ventilation, significantly lowering construction costs and alleviating the burden on residents. Furthermore, thanks to its intelligent features, this utility model elevator also has an early warning function, alerting people to escape as soon as possible in the event of a fire. It clearly identifies the escape routes and safe temporary shelters for all escapees, thereby preventing fire and smoke inhalation. This makes the entire escape and rescue process calm and orderly, greatly improving the efficiency of people's escape and significantly reducing or even eliminating casualties during fires.

[0006] To achieve the above objectives, the utility model proposes a concealed intelligent elevator for the renovation of old residential communities, comprising:

[0007] The elevator comprises an intelligent car, a concealed shaft on the first floor, a fire shelter, an elevator load-bearing structure, an elevator machine room, and a battery installed in the machine room to ensure the power supply for normal operation of the elevator in the event of a fire. Its distinguishing feature is that the concealed intelligent elevator uses a concealed shaft installed on the ground and an electronic grating shaft installed under the intelligent car to replace the physical shaft of a traditional elevator. The fire shelter is located in a non-enclosed space outside the floor, and the elevator doors on the intelligent car directly face the outdoor space, corresponding one-to-one with the fire shelters on each floor. The intelligent car also includes an electronic early warning system and a fire sprinkler system.

[0008] Preferably, the concealed manhole on the first floor is installed on the ground floor, with a manhole cover plate on top.

[0009] The shaft cover has shaft side plates on both sides, and a first-floor elevator door is installed on one side of the shaft cover (the side opposite the wall). The drive device is installed in the lower part of the shaft cover and inside the first-floor concealed shaft. The first-floor concealed shaft is hidden underground when the elevator is not in use. Therefore, the elevator shaft is not visible under normal circumstances, thus eliminating the potential impact of the newly built physical visible elevator shaft on the fire escape route and reducing the impact of the traditional huge physical visible elevator shaft on the lighting and ventilation of the original building.

[0010] Another preferred method for the first-floor concealed shaft is to have a first shaft cover plate and a second shaft cover plate respectively installed on the top two sides of the shaft. Both the first and second shaft cover plates have a pivot at their base. The first and second shaft cover plates are symmetrical to each other. A first-floor elevator door is installed on the other side of the top of the shaft (the side opposite to the wall). A pivot is also installed at the base of the first-floor elevator door. This method of concealing the shaft is also hidden underground when the elevator is not in use, and has the same advantages as the above-mentioned method.

[0011] The preferred intelligent elevator car includes: an intelligent early warning system, a fire sprinkler system, and an electronic light grating. The electronic early warning system includes: smoke sensors installed inside the car and in the living quarters, and control, display, and early warning panels respectively installed inside and outside the car. When each sensor detects a signal, it immediately transmits the signal to the control cabinet. When a set standard is reached, an operation or early warning prompt is issued immediately. The fire sprinkler system includes: a smoke temperature sensor, a miniature air pump, a water storage device, and sprinklers installed inside the car. When the smoke temperature sensor receives a signal, it immediately transmits the signal to the control cabinet. When a set standard is reached, a signal is issued immediately, and the miniature air pump starts automatic sprinkler fire suppression. The fire sprinkler system is installed to prevent people from rushing into the elevator if their clothes catch fire. The electronic light grating shaft is fixedly installed at the bottom of the intelligent elevator car. The electronic light grating shaft automatically starts when the car starts running. When the electronic light grating shaft detects an obstacle, it immediately issues a stop command to the car. The elevator doors on the intelligent elevator car lead directly to the outdoor space and correspond one-to-one with the fire shelter and the elevator doors on the first-floor concealed shaft.

[0012] The preferred method is to use an electronic grating shaft and a concealed shaft on the first floor together to form a shaft that can ensure the safe operation of the elevator. This replaces the traditional visible physical shaft, effectively avoiding the chimney effect and enabling the elevator to continue to operate safely in the event of a fire.

[0013] The preferred elevator load-bearing structure includes a first column located behind the intelligent car. A wall connector is located behind the first column, and an anchor is installed behind the wall connector, fixed to the wall. Both ends of the wall connector are fixedly connected to the first column and the anchor, respectively. Thus, the column is anchored to the wall via the connector, and the two first columns are further fixedly connected as a whole by an inter-column connector, forming a robust elevator load-bearing structure. Since this load-bearing structure is fixedly connected to the original building, its consistency and stability with the original building are guaranteed. The elevator load-bearing structure also includes a closed-loop system. Enclosures are installed on the outer sides of the two connectors on both sides and on the outer sides of the column connector. These three enclosures, together with the wall, form a closed cavity that encloses the counterweight rail, counterweight, wire rope, and electrical wires, effectively protecting these components.

[0014] Preferably, the upper part of the elevator load-bearing structure is provided with an elevator machine room. The elevator machine room includes a hole slightly larger than the intelligent car on the machine room floor directly above the second intelligent car. This allows the car to rise into the machine room when it is not used for a long time, such as during rainy days or at night, so that the car can be well protected.

[0015] The preferred option is to install a battery in the machine room, which adds an extra layer of power protection for the elevator, thereby ensuring that the elevator can still operate normally in the event of an external power supply failure such as a fire.

[0016] The concealed elevator shaft of this utility model is hidden underground when the elevator is not in use. When the elevator descends to the set height, the shaft cover sinks underground under the action of the drive device, and the shaft side plate and the first-floor elevator door rise from underground to form a temporary elevator shaft. When the elevator runs to the first floor, the first-floor elevator door and the inner door of the elevator open together. When the elevator runs upward, and after receiving the instruction, the drive device starts to restore the shaft from the visible state to the hidden underground state.

[0017] Another approach to the concealed shaft on the first floor of this utility model is that when the elevator descends to a set height, under the action of the drive device, the first shaft cover plate, the second shaft cover plate, and the first floor elevator door, which were normally placed horizontally, are flipped upward in sequence to form a temporary shaft. When the elevator moves upward, and after receiving an instruction, the drive device is activated, and the shaft is restored from its ground-level state to a horizontally placed concealed state in sequence, with the first floor elevator door, the second shaft cover plate, and the first shaft cover plate in sequence. Beneficial effects

[0018] 1. This utility model elevator adopts "stealth" technology, which eliminates the need for elevator shafts that originally needed to be built outside the building, thus avoiding conflicts and disputes caused by the ground area occupied by elevator shafts.

[0019] 2. The novel structural form of this utility model avoids the chimney effect formed by flames and smoke during a fire.

[0020] 3. In the event of a fire, all elevators are forced to the first floor, and all elevator doors open automatically and stop operating. However, the elevator of this utility model is equipped with a backup power system to meet the needs of operation and rescue during a fire, thereby increasing the efficiency of rescue and escape.

[0021] 4. This utility model elevator has multiple control modes, namely: conventional operation control mode and fire rescue operation control mode. Attached Figure Description

Detailed Implementation

[0039] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0040] A concealed intelligent elevator for the renovation of old residential communities includes: an intelligent car, a concealed shaft on the first floor, a fire shelter, an elevator load-bearing structure, an elevator machine room, and a battery installed in the machine room. The concealed intelligent elevator uses a concealed shaft installed on the ground and an electronic grating shaft installed under the intelligent car. The fire shelter is located in an open space outside the floor, and the elevator doors on the intelligent car directly face the outdoor space, corresponding one-to-one with the fire shelters on each floor. The intelligent car also includes: an electronic early warning system and a fire sprinkler system.

[0041] The upper part of the concealed shaft on the first floor is equipped with a shaft cover plate, and shaft side plates are provided on both sides of the shaft cover plate. The elevator door on the first floor is provided on the other side of the shaft cover plate (the side opposite to the wall).

[0042] The outer surface of the floor is provided with an open fire shelter, and the fire shelter is provided with an elevator door on the side adjacent to the intelligent elevator car.

[0043] The intelligent elevator car includes: an intelligent early warning system, a fire sprinkler system, and an electronic light grating. The electronic early warning system includes: smoke sensors installed inside the car and in the living quarters, and control, display, and early warning panels installed inside and outside the car. The fire sprinkler system includes: a miniature air pump, a water storage device, and sprinklers installed inside the car. The fire sprinkler system automatically sprays water to extinguish fires after receiving signals from the various sensors and controllers. The electronic light grating shaft is fixedly installed at the bottom of the intelligent elevator car. The elevator doors on the intelligent elevator car lead directly to the outdoor space and correspond one-to-one with the fire shelter and the elevator doors on the first-floor concealed shaft.

[0044] The elevator load-bearing structure includes a first column located behind the intelligent car, a wall connector located behind the first column, and an anchor fixed to the wall located behind the wall connector. The two ends of the wall connector are fixedly connected to the first column and the anchor, respectively. The elevator load-bearing structure also includes a closed cylinder system.

[0045] An elevator machine room is provided on the upper part of the elevator load-bearing structure. The elevator machine room includes a second column, and the interior of the elevator machine room is equipped with a drive motor, a storage battery, a water supply tank, and an elevator control cabinet.

[0046] As shown in Figure 1, this utility model provides a concealed intelligent elevator for the renovation of old residential communities. The concealed intelligent elevator includes: an intelligent car 1, a concealed shaft 2 on the first floor, a fire shelter 3, an elevator load-bearing structure 4, and an elevator machine room 5. The concealed shaft 2 on the first floor is set on the ground, and the fire shelter 3 is set in a non-enclosed space outside the floor. The elevator door 31 on the intelligent car 1 faces the outdoor space directly and corresponds one-to-one with the fire shelter 3 on each floor.

[0047] Figures 2-3As shown, the intelligent car 1 includes a steel wire rope 11, a micro air pump 12, a water storage device 13, a nozzle 14, an elevator smoke sensor 15, an electronic grating shaft 16, a control panel 17, track clips 18, an intelligent car side door 19, and an intelligent car front door 110. The smoke sensor 15, control panel 17, resident indoor temperature and smoke sensor 34 installed inside the elevator, and the elevator control cabinet 54 installed in the elevator machine room 5 together constitute an intelligent early warning system. When each sensor detects a signal, it is immediately transmitted to the elevator control cabinet 54, and an operation or early warning prompt is issued immediately when the set standard is reached. The miniature air pump 12, water storage device 13, and sprinkler heads 14 installed on the top of the intelligent car 1, along with the smoke sensor 15 inside the elevator, constitute a fire sprinkler system. When the smoke sensor 15 receives a signal, it immediately transmits it to the elevator control cabinet 54. When the set standard is reached, a signal is given, and the miniature air pump 12 starts automatic sprinkler fire suppression. The fire sprinkler system is set up to prevent people from rushing into the elevator if their clothes catch fire. The electronic grating shaft 16 is fixedly installed at the bottom of the intelligent car 1. When the intelligent car 1 starts running, the electronic grating shaft 16 automatically starts. When the electronic grating shaft 16 detects an obstacle, it immediately sends a stop command to the car, and the intelligent car 1 stops running immediately. The intelligent car side door 19 is used for residents to get on and off the elevator. It leads directly to the outdoor space and corresponds one-to-one with the elevator door 31 on the fire shelter 3. The intelligent car front door 110 is used for getting on and off the elevator on the first floor. It leads directly to the outdoor space and corresponds one-to-one with the first-floor elevator door 23 on the first-floor concealed shaft 2. The track clamps 18 are symmetrically arranged at the rear of the intelligent car 1 to ensure the smooth up-and-down operation of the intelligent car 1.

[0048] Figures 4-9 As shown, the first-floor concealed shaft 2 includes a shaft cover plate 21, shaft side plates 22, a first-floor elevator door 23, a drive device 24, a first shaft cover plate 25, a second shaft cover plate 26, a clamping element 27, and a rotating shaft 28. The first-floor concealed shaft 2 is installed on the ground floor, with a shaft cover plate 21 on its upper part. Shaft side plates 22 are respectively installed on both sides of the shaft cover plate 21. A first-floor elevator door 23 is installed on one side of the shaft cover plate 21 (the side opposite to the wall). The drive device 24 is installed at the lower part of the shaft cover plate 21 and inside the first-floor concealed shaft 2. The first-floor concealed shaft 2 is normally hidden underground and cannot be seen. Only when the elevator descends to the set height, under the action of the drive device 24, the shaft cover 21 sinks underground, and the shaft side plate 22 and the first-floor elevator door 23 rise from underground to form a temporary elevator shaft. When the elevator reaches the first floor, the first-floor elevator door 23 and the intelligent car main door 110 open together. When the elevator ascends, and after the drive device 24 receives the instruction, the drive device 24 starts to restore the shaft from the visible state to the hidden underground state.

[0049] Another approach to the concealed shaft 2 on the first floor is to have a first shaft cover plate 25 and a second shaft cover plate 26 respectively installed on the top two sides of the shaft. A pivot 28 is installed at the base of both the first shaft cover plate 25 and the second shaft cover plate 26. The first shaft cover plate 25 and the second shaft cover plate 26 are symmetrical to each other. The first shaft cover plate 25, the second shaft cover plate 26, and the first-floor elevator door 23 are normally laid flat and hidden underground. Only when the elevator descends to a set height, under the action of the drive device 24, the first shaft cover plate 25 and the second shaft cover plate 26 are opened. Cover plate 26 and first-floor elevator door 23 rotate around their respective pivot 28. When the first shaft cover plate 25 and the second shaft cover plate 26 rotate to the upright position, they are supported by the bracket 27 fixedly installed on the wall. After all rotations are completed, a temporary shaft is formed. When the elevator runs to the first floor, the first-floor elevator door 23 and the intelligent car main door 110 open together. When the elevator runs upward, and after the drive device 24 receives the instruction, the drive device 24 starts to restore the shaft from the visible state to the hidden state underground.

[0050] The two types of concealed elevator shafts 2 on the first floor are hidden underground when the elevator is not in use and cannot be seen under normal circumstances. This eliminates the potential impact of newly built physical visible elevator shafts on fire escape routes and reduces the impact of traditional, large physical visible elevator shafts on the lighting and ventilation of existing buildings.

[0051] Figure 10 As shown, the fire shelter 3 includes an elevator door 31, a fence 32, a control and warning panel 33, an indoor temperature and smoke sensor 34, a fire door 35, and a floor temperature and smoke sensor 36. The fire shelter 3 is located outside each floor and serves as a passageway and waiting area for people to enter and exit the elevator. A fire door 35 separates the fire shelter 3 from the interior floor. An elevator door 31 is located on the side adjacent to the intelligent elevator car 1, and fences 32 are installed on the other three sides. An indoor temperature and smoke sensor 34 is installed inside each apartment, and floor temperature and smoke sensors are installed on each floor. When the sensors 36 receive a danger signal, the control and warning panel 33 will issue an alarm to alert residents that a fire has occurred and to evacuate as soon as possible. Since the fire shelter 3 is an outdoor, non-enclosed space, people in the fire shelter 3 will not be exposed to smoke or fire. They are in an open space where they are not exposed to fire or smoke, which greatly reduces casualties during a fire. In addition, since it is clear that the fire shelter 3 is a safe place to hide and escape efficiently after a fire breaks out, people will naturally gather there, which can play a role in safely waiting for rescue, which brings great convenience to fire rescue.

[0052] Figure 11As shown, the elevator load-bearing structure 4 includes a first column 41 located behind the intelligent car 1. A wall connector 43 is located behind the first column 41, and an anchor 44, anchored to the wall, is installed behind the wall connector 43. Both ends of the anchor 44 are fixedly connected to the first column 41 and the anchor 44, respectively. Thus, the column is anchored to the wall via the anchor 44. The two first columns 41 are then fixedly connected as a whole by an inter-column connector 45, thereby forming a robust elevator load-bearing structure 4. The load-bearing structure is fixedly connected to the original building, so its consistency and stability with the original building are guaranteed. The elevator load-bearing structure 4 also includes a closed cylinder system, which is formed by setting up a barrier 49 on the outside of the two wall connectors 43 on both sides and the outside of the column connector 45. The barrier 49 on these three sides, together with the wall, form a closed cavity, which encloses the counterweight rail 47, counterweight 48, steel wire rope 11, and wires, etc., in order to effectively protect the above-mentioned objects.

[0053] Figures 12-13 As shown, the upper part of the elevator load-bearing structure 4 is equipped with an elevator machine room 5, including a drive motor 51, a battery 52, a water supply tank 53, an elevator control cabinet 54, and a second column 55. When the elevator receives an instruction to move up or down, the drive motor 51 operates, pulling the steel cable 11 to raise or lower the intelligent car 1. In the event of a fire or other emergency, if the elevator's main power supply is cut off, the battery 52 will immediately supply power to the elevator, ensuring normal operation during rescue operations. When the water in the water storage device 13 of the intelligent car 1 is depleted, water is replenished to the storage device 13 through the water supply tank 53 in the elevator machine room 5 to meet rescue needs. The elevator control cabinet 54 in the elevator machine room 5 is set up to meet daily maintenance and upkeep requirements. The intelligent car 1 is controlled to enter the elevator machine room 5 for maintenance and upkeep through the elevator control cabinet 54.

[0054] Figure 14 The diagram shown is an operation flowchart of a ground protection structure for a hidden intelligent elevator in the renovation of an old residential area, which introduces the operation process of the ground protection structure.

[0055] Figure 15 The diagram shown is an overall operation flow chart of an elevator that can still be used in the event of a fire, illustrating the operation process of the entire intelligent elevator system.

[0056] (a) Normal working mode

[0057] (1) After the elevator system receives the up or down button signal of a certain floor, the intelligent car 1 starts the bottom electronic safety light curtain 16. If the electronic safety light curtain 16 detects an obstacle, it stops and sounds an alarm until there is no obstacle. If there is no obstacle, the drive motor 51 of the intelligent car 1 starts and stops the intelligent car 1 at the button signal floor. The drive motor 51 stops working.

[0058] (2) After the intelligent car 1 arrives at the floor indicated by the button signal, the elevator door 31 and the intelligent car side door 19 will open automatically to facilitate the entry and exit of personnel. The elevator door 31 can be closed manually or automatically after a delay.

[0059] (3) As soon as the elevator system receives the button signal of the first floor, the drive device (24) of the first floor invisible shaft 2 will start working and drive the invisible shaft 2 to emerge from the ground. One way to raise it out of the ground is: the shaft cover plate 21 moves downward to leave space for the intelligent car 1 to go down. The drive device 204 works and the shaft side plate 22 moves upward, thus forming a temporary elevator shaft. When the intelligent car 1 runs to the first floor set elevation, the first floor elevator door 23 and the intelligent car main door 110 open at the same time, and people enter and exit the intelligent car 1. Another way to form a ground shaft is: the first shaft side cover plate 25 and the second shaft side cover plate 26 flip upward around the pivot 28 one after another. The first floor elevator door 23 follows the shaft side cover plate and flips upward. When all three are flipped to the ground and fixed with the clip 27, a temporary elevator shaft is formed. When the intelligent car 1 runs to the first floor set elevation, the first floor elevator door 23 and the intelligent car main door 110 open at the same time, and people enter and exit the intelligent car 1. The transition from a temporary to a concealed state of the shaft requires the elevator's operating program to be configured according to the set conditions and corresponding instructions. The entire operation of the intelligent car 1 and the concealed shaft 2 only begins after the safety light curtain 16 detects no obstacles; otherwise, a warning sound will be emitted.

[0060] (4) When a person enters the smart car 1 and presses the floor they want to go to, the elevator door 23 on the first floor and the main door 110 of the smart car will close at the same time. The smart car 1 will start the bottom electronic safety light curtain 16. If the safety light curtain 16 detects an obstacle, it will stop and sound an alarm until there is no obstacle. If there is no obstacle, the drive motor 51 of the smart car 1 will start and stop the smart car 1 at the button signal floor. The drive motor 51 will stop working.

[0061] (5) After the intelligent car 1 arrives at the floor indicated by the button signal, the elevator door 31 and the intelligent car side door 19 will open automatically to facilitate the entry and exit of personnel. The elevator door 31 can be closed manually or automatically after a delay.

[0062] (6) After a transport operation is completed, if there is no signal during the delay period, the smart car 1 will return to the initial set position, and the first-floor invisible shaft 2 will return to its initial state.

[0063] (7) At night, in rainy weather, or when the control system determines that the elevator may not be used for a period of time, the intelligent car 1 will automatically rise into the elevator machine room 5 to better protect the intelligent car 1.

[0064] (II) Fire Rescue Mode

[0065] (1) In fire rescue mode, the intelligent car 1 automatically switches to the power supply mode of the storage battery 52.

[0066] (2) The intelligent car 1 will automatically reach the floor where the temperature and smoke sensor 36 first alarms, sound a buzzer, and wait for people to enter and exit the intelligent car 1 for priority rescue. If there is no response for a long time on the priority rescue floor, the signaled task will be executed.

[0067] (3) After a successful rescue, the elevator will prioritize tasks with a signal. If there is no signal, the smart car 1 will be moved up or down to the floor above or below the abnormal floor. If the abnormal floor is the top floor when the temperature and smoke sensor 36 is detected for the first time, the elevator will move up to the floor below the abnormal floor the next time. Otherwise, the elevator will move up to the floor above the abnormal floor the next time.

[0068] The above description is merely an example and illustration of the present utility model. Those skilled in the art can substitute similar methods for the specific embodiments described, as long as they do not deviate from the structure of the present utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
