Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to an elevator shaft environment adaptive detection device. Background Art

[0002] In the existing technology, as an indispensable vertical transportation tool in modern buildings, the safety and comfort of elevator operation have always attracted much attention. Traditional elevator systems often focus on basic transportation functions, but have many deficiencies in environmental monitoring, energy utilization and intelligent control.

[0003] First, in terms of environmental monitoring, traditional elevator systems lack comprehensive hoistway environmental monitoring methods. The elevator hoistway is a key space for elevator operation, and its internal environmental conditions (such as temperature, humidity, dust concentration, etc.) directly affect the elevator's operating performance and passengers' riding experience. However, existing technologies often lack real-time and accurate monitoring methods, which may lead to elevator failures or performance degradation when operating under harsh environmental conditions.

[0004] Secondly, in terms of energy utilization, traditional elevator systems mainly rely on power grids and lack effective means of energy self-sufficiency. With the intensification of the energy crisis and the improvement of environmental awareness, how to reduce the energy consumption of elevator systems and improve energy efficiency has become an urgent problem to be solved. Although there are some energy-saving measures in the existing technology, they are often limited in effect and fail to fully utilize the potential energy generated during the operation of the elevator.

[0005] In addition, traditional elevator systems also have many deficiencies in terms of intelligent control. For example, the ventilation control of elevators often adopts a fixed mode and cannot be intelligently adjusted according to the actual conditions such as the elevator load and running direction. This may not only lead to energy waste, but also cause unnecessary noise and discomfort to passengers. At the same time, the intelligence level of existing elevator systems in dealing with emergencies needs to be improved, such as the lack of effective emergency lighting and emergency device power supply solutions.

[0037] like Figure 1-Figure 8 As shown,

[0038] An elevator shaft environment adaptive detection device, characterized in that it includes the following components:

[0039] The car mechanism 1 comprises a car bottom 11 and a car wall 12. The car wall 12 is fixedly arranged around the car bottom 11. A bottom plate 14 is arranged on the upper side of the car bottom 11 through a spring expansion sleeve 13.

[0040] The detection box 2 is fixedly arranged on the lower side of the car bottom 11 and a part of the upper side of the detection box 2 is located outside the car bottom 11. The detection box 2 includes a box body 21. The upper end side and the lower end side of the box body 21 are rotatably provided with door panels 22 respectively. A wind turbine 23 is fixedly arranged on the inner lower part of the box body 21. The front and rear sides of the inner upper part of the box body 21 are respectively provided with a detection module 24 and a power storage module 25. A ventilation channel 26 is provided between the power storage module 25 and the detection module 24.

[0041] The linkage mechanism 3 is used to drive the door panels 22 at the upper and lower ends of the detection box 2 to open automatically when the base plate 14 is pressed down. The linkage mechanism 3 includes a pressure rod 31 rotatably arranged in the middle on the car bottom 11, and a torsion spring 32 is arranged at the rotation connection between the pressure rod 31 and the car bottom 11. A slide groove 33 is fixedly arranged at the position corresponding to the upper end of the pressure rod 31 on the lower side of the base plate 14. The upper end of the pressure rod 31 is slidably arranged inside the slide groove 33. A first connecting rod 34 is fixedly arranged on the outer end side of the rotating structure of the door panel 22, and a sliding sleeve 35 is slidably arranged on the outer side of the first connecting rod 34. The outer end of the sliding sleeve 35 is hinged with a second connecting rod 36, and the outer end of the second connecting rod 36 is hinged with a moving frame 37. The moving frame 37 is slidably connected to the outer side of the box body 21, and a sliding groove 38 is arranged at the inner end of the moving frame 37. The lower end of the pressure rod 31 is slidably arranged on the inner side of the sliding groove 38.

[0042] The detection module 24 includes one or more of a temperature sensor, a humidity sensor, a dust sensor, an electromagnetic interference sensor, an infrared sensor, a gas sensor, a camera, a sonar sensor and a vibration sensor and is arranged in a matrix.

[0043] like Figure 4 As shown, a ventilation gap 4 is arranged between the end side of the bottom plate 14 close to the detection box 2 and the car wall 12, a limiting block 5 is fixedly arranged on the inner side of the car wall 12 and below the ventilation gap 4, one end of the bottom plate 14 close to the ventilation gap 4 is arranged as an inclined surface 141, and the inner end side of the limiting block 5 is arranged with an inclined surface 51 matching the inclined surface 141 of the bottom plate 14, a ventilation groove 6 is arranged at the position of the inner end side of the limiting block 5 near the car bottom 11, and a bent ventilation pipe 7 is fixedly arranged on the lower side of the car bottom 11 and at the position corresponding to the ventilation groove 6, and the other end of the bent ventilation pipe 7 is fixedly connected to the rear side of the detection box 2 and the interior of the bent ventilation pipe 7 is communicated with the interior of the detection box 2.

[0044] like Figure 4As shown, the side of the limit block 5 is in a right-angle trapezoid, one side of the right angle of the limit block 5 is fixedly arranged on the inner side of the car wall 12, and the width of the upper side of the limit block 5 is the same as the width of the ventilation gap 4. The ventilation gap 4 is located on the side of the car away from the car door, and the width is set between 2cm and 8cm, which is not easy to touch, thereby reducing the discomfort caused by the ventilation gap 4 to the load-bearing personnel.

[0045] like Figure 2 and Figure 3 As shown, a debris collection box 8 is fixedly provided at the lower side of the bending of the bent ventilation pipe 7, the upper end side of the debris collection box 8 is communicated with the interior of the bent ventilation pipe 7, and the lower end of the debris collection box 8 is provided with an openable box cover 9.

[0046] like Figure 3 As shown, pressure sensors 10 are evenly arranged on the sides between the bottom plate 14 and the car bottom 11 .

[0047] like Figure 6 As shown, the spring telescopic sleeve 13 includes a telescopic rod 131 , a telescopic sleeve 132 slidably disposed on the outside of the telescopic rod 131 , and a compression spring 133 sleeved on the outside of the telescopic rod 131 .

[0048] like Figure 5 , Figure 7 and Figure 8 As shown, the door panel 22 is a double-open door panel, each door panel 22 corresponds to a set of first connecting rods 34 and sliding sleeves 35, and the sliding sleeves 35 located at the same end side of the detection box 2 share a second connecting rod 36. The door panels 22 at the upper and lower ends of the detection box 2 can be controlled to open or close at the same time through the linkage mechanism 3, which is convenient to control. When the door panel 22 at the lower end of the detection box 2 is opened, the double-open door panel 22 will flip toward the inside of the detection box 2, and the double-open door panel 22 will form a trumpet with the inner wall of the detection box 2, thereby playing a wind gathering effect, which is conducive to increasing the air flow speed and improving the efficiency of power generation. When the door panel 22 at the upper end of the detection box 2 is opened, the double-opened door panel 22 at the upper end will also flip toward the inside of the detection box 2, and the double-opened door panel 22 will be tilted to cover the upper side of the detection module 24 and the power storage module 25 respectively, thereby protecting the detection module 24 and the power storage module 25. Even if objects fall from the upper part of the detection box 2 to the inside of the detection box 2, the detection module 24 and the power storage module 25 will not be damaged.

[0049] like Figure 3 , Figure 7 and Figure 8 As shown, when the bottom plate 14 is pressed down, the linkage mechanism 3 drives the door panels 22 at the upper and lower ends of the detection box 2 to close; when the bottom plate 14 is not pressed down, the linkage mechanism 3 drives the door panels 22 at the upper and lower ends of the detection box 2 to close.

[0050] like Figure 5As shown, the wind turbine 23 is fixedly arranged at the middle position of the lower inner side of the detection box 2, and a partition 27 is arranged between the front and rear sides of the wind turbine 23 and the inner wall of the detection box 2. A bending guide plate 28 is arranged at the front side of the detection box 2 and between the detection module 24 and the wind turbine 23, and the rear side of the bending guide plate 28 extends to the rear side of the wind turbine 23. When the elevator moves up and down and the door panel 22 is opened, the airflow will enter the detection box 2 from the upper or lower part, and the bending guide plate 28 can better reverse the airflow into the bending ventilation pipe 7. Moreover, when there is falling objects in the hoistway entering the detection box 2 from the upper side, due to the shielding of the bending guide plate 28, the falling objects will not fall to the upper side of the fan generator 23, so as to avoid the falling objects from causing damage to the generator. The falling objects will enter the bending ventilation pipe 7 and finally enter the debris collection box 8 or the falling objects enter the partition 27, and then regular maintenance is performed.

[0051] like Figure 1-Figure 8 As shown,

[0052] The present invention provides an elevator shaft environment adaptive detection device, which is intended to monitor the environmental conditions in the elevator shaft in real time to ensure the safety and comfort of elevator operation. The device integrates multiple sensors and controls the power generation of the wind turbine and the ventilation in the car mechanism 1 through an intelligent linkage mechanism.

[0053] Car mechanism 1

[0054] The car platform 11 is a bottom support structure of the car mechanism 1 and bears the weight of passengers and cargo.

[0055] The car wall 12 is arranged around the car bottom 11 to form a closed riding space.

[0056] The spring telescopic sleeve 13 includes a telescopic rod 131, a telescopic sleeve 132 and a compression spring 133, which is used to buffer the vibration during the operation of the elevator and improve the riding comfort. At the same time, the elasticity of the spring telescopic sleeve 13 also provides space for the bottom plate 14 to move up and down.

[0057] Bottom plate 14: Located on the upper side of the car bottom 11, connected to the car bottom 11 through a spring expansion sleeve 13, the bottom plate 14 can be controlled to move up and down according to whether there is a load in the elevator car.

[0058] Detection box 2

[0059] Box body 21: as a carrier of the detection module 24 and the power storage module 25, it has waterproof and dustproof functions.

[0060] Door panel 22: Double-opening door panel design, opening and closing are controlled by linkage mechanism 3, which controls the power generation of wind turbine 23 and ventilation in car mechanism 1, and at the same time has a certain protection effect on detection module 24 and power storage power module 25.

[0061] Wind turbine 23: During the descent of the elevator, the airflow is used to generate electricity, which is stored in the power storage module 25 and provides power for the detection module 24, the pressure sensor 10, and the backup lighting.

[0062] Detection module 24: includes temperature sensors, humidity sensors, dust sensors and other sensors, arranged in a matrix to comprehensively monitor the shaft environment.

[0063] Power storage module 25: stores electric energy to ensure that the detection module can still work normally when the wind turbine 23 fails to supply power or when the elevator fails.

[0064] Ventilation channel 26: located between the power storage module 25 and the detection module 24, to promote air circulation and prevent the sensor from overheating.

[0065] Linkage mechanism 3

[0066] The pressure rod 31: The middle part is rotatably arranged on the car bottom 11, and is connected to the bottom plate 14 through the slide groove 33. When the bottom plate 14 is pressed down, the pressure rod 31 rotates accordingly.

[0067] Torsion spring 32: provides a restoring force for the pressure rod 31 to ensure that the pressure rod 31 can return to the initial position when the bottom plate 14 is not under pressure.

[0068] The first connecting rod 34 , the sliding sleeve 35 , the second connecting rod 36 , and the moving frame 37 constitute a connecting rod mechanism, which converts the rotation of the pressure rod 31 into the opening and closing action of the door panel 22 .

[0069] Ventilation gap 4, limit block 5, ventilation slot 6, bent ventilation pipe 7

[0070] Ventilation gap 4 : located between the bottom plate 14 and the car wall 12 , allowing air to circulate to the detection box 2 .

[0071] The limit block 5 prevents the bottom plate 14 from being overly pressed downward. At the same time, its inclined surface 51 cooperates with the inclined surface 141 of the bottom plate 14 to guide air into the ventilation slot 6 .

[0072] The ventilation slots 6 and the bent ventilation pipes 7 constitute an air circulation path. When the bottom plate 14 is not pressed down and when the elevator moves up and down, the air in the hoistway is introduced into the detection box 2 and part of it enters the interior of the car mechanism.

[0073] Debris collection box 8, box cover 9

[0074] The debris collection box 8 is located at the lower side of the bend of the bent ventilation pipe 7, and collects debris and impurities that fall through the ventilation gap 4 in the car to prevent them from entering the detection box 2 or blocking other pipe grooves, thereby maintaining smooth ventilation.

[0075] Box cover 9: The box cover 9 can be opened to facilitate cleaning of impurities in the debris collection box 8.

[0076] Pressure sensor 10: Evenly arranged between the bottom plate 14 and the car bottom 11, monitors the pressure on the bottom plate 14. When the position of the person standing on the upper side of the bottom plate is too biased to one side, the person inside the car can be reminded by voice to adjust the position so that the position of the people inside the car is even.

[0077] The detection module 24 of the present invention detects that the process of power generation by the wind turbine 23 and ventilation in the car mechanism 1 is as follows:

[0078] The detection module 24 of the present invention is powered by the power storage power module 25, and can continuously and in real time detect the environment in the elevator shaft. Even if the elevator fails and the power is cut off (for example, a fire occurs), the detection module 24 can understand the situation of the elevator shaft from the outside through wireless transmission. If there are people trapped in the elevator, rescue personnel can better rescue them.

[0079] The wind turbine 23 of the present invention generates electricity by utilizing the airflow generated when the elevator moves downward. The generated current is stored in the power storage module 25, so that it can supply power to the detection module 24 or the emergency lighting or emergency rescue device inside the elevator, which is beneficial to saving electric energy.

[0080] When the elevator is loaded with objects, the bottom plate 14 will not be pressed down, so the linkage mechanism 3 composed of the pressure rod 31, the first connecting rod 34, the sliding sleeve 35, the second connecting rod 36 and the moving frame 37 will not be started. At this time, the door panel 22 is in an open state. When someone presses the elevator button on different floors at this time, the elevator will move upward or downward under control; when the elevator moves downward, the wind turbine 23 generates electricity, and a part of the airflow entering the detection box 2 during power generation will pass through the inside of the detection box 2 and enter the bent ventilation pipe 7, and then pass through the ventilation slot 6, the space between the inclined surface 51 and the inclined surface 141 and the ventilation gap 4 in sequence to enter the interior of the car mechanism 1, which can greatly increase the air flow in the car mechanism 1; when the elevator moves upward, the wind turbine 23 cannot generate electricity, and a part of the airflow entering the detection box 2 from the upper part of the detection box 2 can still enter the car mechanism 1, increasing the air flow in the car mechanism 1. Due to the setting structure of the detection box 2, and the fact that the airflow will generate a large noise when entering the wind turbine 23 and other pipe groove structures, the present invention can be set so that when there are people loaded in the car mechanism 1, the generator does not generate electricity and the airflow does not enter the interior of the detection box 2, so as to reduce the noise pollution caused by the detection box 2 to the interior of the car, and at the same time avoid the discomfort caused to the load-bearing personnel due to the large airflow. Specifically, when there are people loaded in the car mechanism 1, the bottom plate 14 is pressed down, the pressure rod 31 will rotate a certain angle, and the moving frame 37 will slide horizontally, thereby driving The second connecting rod 36, the first connecting rod 34 and the sliding sleeve 35 move, so that the door panel 22 is closed. At this time, no matter whether the elevator moves up or down, no airflow will enter the detection box 2. Since air leakage may occur at the rotation point of the pressure rod 31 and the car bottom 11, when the bottom plate 14 is pressed down, the inclined surface 51 and the inclined surface 141 will fit each other, which can further block the airflow from entering the interior of the car. At this time, the inner bottom surface of the car (the upper side surface of the bottom plate 14 and the upper side surface of the limit block 5) will form a flat surface, which will not cause discomfort to the passengers.

[0081] The data collected by the detection module 24 is transmitted to the elevator control system or remote monitoring center through internal circuits or wirelessly for real-time analysis and processing to ensure the safety and comfort of elevator operation.

[0082] If there are small debris in the elevator that enters between the inclined surface 51 and the inclined surface 141 through the ventilation gap 4, since the wind in the bent ventilation duct 7 is either blowing upward toward the ventilation gap 4 or there is no wind, the debris will be blown back to the vicinity of the ventilation gap 4 or eventually fall into the debris collection box 8. The box cover 9 is opened regularly to clean the impurities in the debris collection box 8 to ensure that the air circulation path is unobstructed.

[0083] The preferred implementation modes of the present application are described in detail above, but the present application is not limited to the above implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present application.
