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

The linkage mechanism 3 can simultaneously control the simultaneous opening or closing of the door plates 22 at the upper and lower ends of the detection box 2, and the control is convenient. When the door plate 22 at the lower end of the detection box 2 is opened, the double-opening door plate 22 will be turned inward to the inside of the detection box 2, and the double-opening door plate 22 will form a horn with the inner wall of the detection box 2, thereby achieving the effect of wind gathering, which is beneficial to increasing the airflow speed and improving the power generation efficiency.

When there is a falling object in the hoistway and the falling object enters the inside of the detection box 2 from the upper side of the detection box 2, the falling object will not fall to the upper side of the wind turbine generator 23 due to the shielding of the bent flow guide plate 28, so as to avoid damage to the generator caused by the falling object. The falling object will enter the bent ventilation pipe 7 and finally enter the debris collection box 8 or the falling object will enter the groove 27, and then regular maintenance is needed.

[0051] As shown, Figures 1-8

[0052] The present application is an elevator shaft environment adaptive detection device, which aims to monitor the environmental conditions in the elevator shaft in real time and ensure the safety and comfort of the elevator operation.

[0057] Bottom plate 14: located on the upper side of the car bottom 11 and connected to the car bottom 11 through the spring telescopic sleeve 13, which can control the up and down movement of the bottom plate 14 according to whether there is a load in the elevator car.

[0058] Detection box 2

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

[0060] Door plate 22: double-door design, controlled to open and close through the linkage mechanism 3, to control the power generation of the wind turbine 23 and the ventilation in the car mechanism 1, and to have a certain protective effect on the detection module 24 and the storage power supply module 25.​

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

[0062] Detection module 24: Including temperature sensors, humidity sensors, dust sensors, and various sensors arranged in a matrix, fully monitoring the shaft environment.

[0063] Power storage module 25: Stores electrical energy to ensure that the detection module can still work normally when the wind power generator 23 cannot provide power or when the elevator fails.

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

[0065] Linkage mechanism 3

[0066] Compression rod 31: Rotatably arranged in the middle of the car bottom 11, connected to the bottom plate 14 through the sliding groove 33, when the bottom plate 14 is pressed down, the compression rod 31 rotates with it.

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

[0068] First connecting rod 34, sliding sleeve 35, second connecting rod 36, moving frame 37: Form a connecting rod mechanism to convert the rotation of the compression rod 31 into the opening and closing action of the door plate 22.

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

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

[0071] Limit block 5: Prevents the bottom plate 14 from being pressed too much, and its inclined surface 51 cooperates with the inclined surface 141 of the bottom plate 14 to guide air into the ventilation groove 6.

[0072] Ventilation groove 6, bent ventilation pipe 7: Form an air flow path that introduces air from the shaft into the detection box 2 and part of it into the interior of the car mechanism when the bottom plate 14 is not pressed and when the elevator is moving up and down.

[0073] Debris collection box 8, box cover 9

[0074] Debris collection box 8: Located at the lower side of the bend of the bent ventilation pipe 7, collects debris and impurities that fall inside the car through the ventilation gap 4, prevents them from entering the detection box 2 or clogging other pipes and grooves, and maintains smooth ventilation.

[0075] The box cover 9 is of openable design, facilitating the cleaning of impurities in the sundry collecting box 8.

[0076] The pressure sensor 10 is uniformly arranged between the bottom plate 14 and the car bottom 11, and monitors the pressure received by the bottom plate 14; when the people standing on the upper side of the bottom plate stand too much on one side, the people inside the car can be reminded to adjust the standing position through voice, so that the people inside the car stand evenly.

[0077] The detection module 24 detects that the wind-driven generator 23 generates electricity and the ventilation process in the car mechanism 1 is as follows:

[0078] The detection module 24 of the present application is powered by the power storage module 25, and can continuously and real-timely detect the environment in the elevator shaft; even if the elevator fails and is powered off (such as a fire), the detection module 24 can understand the situation of the elevator shaft from the outside through wireless transmission, and if there are people trapped in the elevator, the rescue personnel can better rescue them.

[0079] The wind-driven generator 23 of the present application utilizes the airflow generated when the elevator moves downward to generate electricity, and the generated current is stored in the power storage module 25, so that the detection module 24 or the emergency lighting or emergency rescue device inside the elevator can be powered, which is beneficial to save electric energy.

[0080] When the elevator is carrying load, the bottom plate 14 will not be depressed, 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 start, at this time the door plate 22 is in an open state, when someone presses the elevator button at different floors at this time, the elevator will control the upward or downward movement; when the elevator moves downward, the wind turbine 23 generates electricity at the same time, part of the airflow entering the detection box 2 will pass through the inside of the detection box 2 into the bent ventilation pipe 7, and then successively pass through the ventilation slot 6, the inclined surface 51 and the inclined surface 141 and the ventilation gap 4 into the inside of the car mechanism 1, so that the air flow in the car mechanism 1 can be greatly increased; when the elevator moves upward, the wind turbine 23 cannot generate electricity, 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 airflow entering the wind turbine 23 and other pipe slot structures will produce a relatively large noise, so the present application can be set to not generate electricity when there is a load of people in the car mechanism 1, and the airflow will not enter the inside of the detection box 2, to reduce the noise pollution caused by the detection box 2 to the inside of the car, and to avoid the discomfort caused by the large airflow when carrying people, in detail, when there is a load of people in the car mechanism 1, the bottom plate 14 is depressed, the pressure rod 31 is rotated by a certain angle, the moving frame 37 is horizontally slid, thereby driving the second connecting rod 36 and the first connecting rod 34, the sliding sleeve 35 to move, so that the door plate 22 is closed, at this time, no matter the upward or downward movement of the elevator, the airflow will not enter the inside of the detection box 2, due to the possibility of air leakage at the rotating part of the pressure rod 31 and the car bottom 11, but when the bottom plate 14 is depressed, the inclined surface 51 and the inclined surface 141 will be in close contact with each other, which can further block the airflow from entering the inside of the car, and at this time the inside bottom surface of the car (the upper side surface of the bottom plate 14 and the upper side surface of the limiting 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 the remote monitoring center through internal circuit or wireless mode for real-time analysis and processing to ensure the safety and comfort of the elevator operation.

[0082] If there is a small debris in the elevator entering the inclined surface 51 and the inclined surface 141 through the ventilation gap 4, due to the upward blowing wind in the bent ventilation pipe 7 or no wind, the debris will be blown back to the vicinity of the ventilation gap 4 or will eventually fall into the debris collection box 8, the lid 9 is opened regularly to clean the impurities in the debris collection box 8 to ensure the smoothness of the air flow path.

[0083] The preferred embodiments of the present application have been described in detail, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present application.
