AI Technical Summary
In existing subway security equipment, the gap between the conveyor belt and the storage rack can easily cause passengers' fingers or palms to be pinched, causing accidents. In addition, the existing anti-pinch device needs to be disassembled separately when the security inspection machine is inspected and repaired, and its intelligence level is low, making it impossible to prevent accidents in a timely manner.
It uses an intelligent lifting anti-pinch plate, equipped with a speed sensor and an induction sensor, and monitors the conveyor belt status in real time through the 5G wireless communication module. When the induction sensor detects that a human body or object enters the gap, the controller stops the conveyor belt operation and the anti-pinch plate can be raised and lowered to facilitate the inspection of the security inspection machine.
Effectively prevent fingers and objects from being pinched, improve the safety and reliability of security inspection equipment, reduce accident risks, simplify the maintenance process, improve intelligence, and reduce costs.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of anti-pinch plates, and in particular to an intelligent lifting anti-pinch plate for subway security inspection equipment. Background Art
[0002] Subways are a form of high-speed, high-capacity rail transit in cities. To ensure operational safety, security equipment is often installed before subway gates to inspect passengers' luggage and belongings for prohibited items. Existing security equipment typically consists of a security machine body and a storage rack. The security machine typically uses a belt conveyor to transport passengers' belongings to the security machine body for irradiation inspection. However, due to the high passenger flow at subway stations during peak hours, security equipment accidents are common. The security machine's conveyor belt is always in operation. As a moving component, it is often not completely sealed from the surrounding support channels. A gap exists at the joint between the security machine's conveyor belt and the storage rack to prevent direct contact and friction, which could cause damage. While the conveyor belt is in operation, a passenger's finger or hand could accidentally get caught in the belt and cause an accident. News reports of injuries caused by security machines are common. To prevent pinching, "Caution Hand Pinch" warning signs are often placed near the gaps between the conveyor belts and storage racks of security checkpoints. However, due to the active nature of children, these warning signs are rarely effective, and cases of children's hands getting caught in conveyor belts are common. Accidents involving children's hands and feet getting caught in the joints of security checkpoints have become a serious problem in recent years. Such accidents frequently occur at security checkpoints, causing not only personal injury but also a serious impact on subway operational safety, necessitating urgent improvements. Currently, research on anti-pinch devices for subway security checkpoints mostly involves attaching them to the bottom of the conveyor belt within the main body of the security checkpoint. While this method provides some protection, it requires separate removal for maintenance, resulting in low reliability, time-consuming, and labor-intensive work. Furthermore, the system cannot detect accidental pinching, resulting in a low level of intelligence, making it difficult to take immediate action before an incident occurs. Summary of the Invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figures 1 to 4As shown: This embodiment provides an intelligent lifting anti-pinch plate for subway security inspection equipment, which is used to be set on one side of a security inspection machine 9 at different heights, including an anti-pinch plate body 13, a speed sensor 1, an inductive sensor 2, a 5G wireless communication module 14, two lifting structures and two mounting seats 4. The two mounting seats 4 are set on one side of the security inspection machine 9, each lifting structure is set on the anti-pinch plate body 13, each lifting structure is connected to a mounting seat 4, and the lifting structure drives the lifting of the anti-pinch plate body 13. The speed sensor 1 and the inductive sensor 2 are both set on the anti-pinch plate body 13. The speed sensor is preferably based on infrared The speed sensor of the line, the speed sensor 1 is used to detect the speed of the conveyor belt 11 of the security inspection machine 9, the inductive sensor 2 is preferably an infrared sensor, the inductive sensor 2 is used to detect whether human body parts or objects enter the gap between the conveyor belt 11 and the storage rack 10 of the security inspection machine 9, the 5G wireless communication module 14 is used to transmit data and control signals, and the signals detected by the speed sensor 1 and the inductive sensor 2 are transmitted to the controller of the security inspection machine 9 through the 5G wireless communication module 14. When the inductive sensor 2 detects a human body or object signal, the controller stops the movement of the conveyor belt 11 to avoid pinching hands or objects. The shape of the anti-pinch plate body 13 can be adjusted according to the shape of the security inspection machine 9. The anti-pinch plate body 13 is located on one side of the security inspection machine 9 and is used to block the gap between the conveyor belt 11 and the storage rack 10 of the security inspection machine 9. It can provide protection while being beautiful, and can effectively prevent pinching hands or objects, prevent the "hand-eating" problem of the security inspection machine 9, and can also prevent packages from falling, thereby ensuring the normal operation of the security inspection machine 9. The intelligent lifting anti-pinch plate used in the subway security inspection equipment of this embodiment is separated from the security inspection machine 9 body, is easy to install, and eliminates the need for complex structures. When a part of the human body enters the "gap" area, the inductive sensor 2 immediately senses the presence of the human body or object, and sends a signal through the 5G wireless communication module 14. The controller of the security inspection machine 9 receives the signal and processes it immediately, commanding the conveyor belt 11 to stop running. When the human body leaves or no human body or object signal is detected, a normal operation signal of the conveyor belt 11 is sent, thereby ensuring the normal operation of the security inspection machine 9. By installing the speed sensor 1 and the inductive sensor 2 on the anti-pinch plate body 13, real-time monitoring of the running status of the conveyor belt 11 can be achieved by wirelessly transmitting signals to prevent the conveyor belt 11 from pinching hands or objects. This embodiment has the advantages of easy installation, economical and applicable, sensitive response, efficient operation, safety and reliability. It does not require changing the structure of the security inspection machine 9, has a small installation workload, and is low in cost.
[0031] Specifically, in this embodiment, a visual window 6 is provided on the anti-pinch plate body 13 for observing the operating status of the conveyor belt 11 and the safety of the passengers' packages.
[0032] In this embodiment, a battery 3 is provided on the back side of the anti-pinch plate body 13 (the side facing the security inspection machine 9), and the battery 3 is electrically connected to the speed sensor 1, the induction sensor 2, the electric cylinder 17 of the lifting structure, and the 5G wireless communication module 14 through a wire 16.
[0033] In this embodiment, the back of the anti-pinch plate body 13 is provided with two vertical grooves 15, each of which houses a lifting mechanism. The lifting mechanism comprises an electric cylinder 17 and a telescopic rod 18. The threaded section 19 of the telescopic rod 18 is threadedly connected to the mounting base 4. The other end of the telescopic rod 18 is connected to the telescopic end of the electric cylinder 17. The cylinder body of the electric cylinder 17 is connected to the upper end of the anti-pinch plate body 13.
[0034] Alternatively, one end of the telescopic rod 18 is connected to the upper end of the anti-pinch plate body 13 , and the other end of the telescopic rod 18 is connected to the telescopic end of the electric cylinder 17 , and the cylinder body of the electric cylinder 17 is connected to the mounting seat 4 .
[0035] In this embodiment, a lifting switch 7 is provided on the anti-pinch plate body 13. The lifting switch 7 includes a start / stop switch, an up switch and a down switch. Press the start switch to start the electric cylinder 17, and press the up / down switch to control the electric cylinder 17 to drive the telescopic rod 18 to extend and retract to drive the anti-pinch plate body 13 to move up and down until it reaches the height desired by the user, meeting the normal operation and maintenance requirements of the security inspection machine 9.
[0036] In this embodiment, an inner groove 8 is provided on the back of the anti-pinch plate body 13 , and the speed sensor 1 and the inductive sensor 2 are both arranged in the inner groove 8 . The speed sensor 1 and the inductive sensor 2 are both 5G wireless sensors.
[0037] In this embodiment, side panels 5 are provided on both sides of the anti-pinch plate body 13 . Each side panel 5 is provided with an anti-collision strip and has a flange without sharp angles to prevent cutting hands and scratching the conveyor belt 11 .
[0038] The position of the anti-pinch plate body 13 of this embodiment corresponds to the gap between the rotating roller 12 of the conveyor belt 11 of the security inspection machine 9 and the storage rack 10, and is used to block the gap between the rotating roller 12 and the storage rack 10. By integrating multiple sensors into the anti-pinch plate body 13, the real-time operating status of the security inspection machine 9 and the conveyor belt 11 is obtained. The sensors then collect and pre-process the data, and the measurement results are output to the controller of the security inspection machine 9 via the 5G wireless communication module 14. The operation of the conveyor belt 11 of the security inspection machine 9 is monitored via the built-in speed sensor 1. When a human body part or object enters the "gap" area, the inductive sensor 2 transmits the detection signal to the controller of the security inspection machine 9 via the 5G wireless communication module 14. The controller of the security inspection machine 9 then commands the conveyor belt 11 to stop, effectively preventing the pinching of hands or objects. When the human body leaves or no human or object signal is detected, a normal operation signal for the conveyor belt 11 is issued, thereby ensuring the normal operation of the security inspection machine 9. According to the daily needs of the security inspection machine, the height of the anti-pinch plate can be adjusted by the control switch when necessary to keep the anti-pinch plate at an ideal height. When maintenance is required, the anti-pinch plate can be lowered to the lowest position by the control switch without hindering the inspection work.
[0039] This embodiment solves the problems of subway security inspection machines 9 pinching hands and objects, "eating hands", the inability to adjust the anti-pinch plate, and the low level of intelligence. This embodiment has a simple structure and is easy to install. The anti-pinch plate body 13 can be raised and lowered and started and stopped at any time without scratching the conveyor belt 11, making it easy to repair the security inspection machine 9.
[0040] The present invention aims at improving the structure, and the control process of the controller is the existing technology.
[0041] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
