[0001] This application relates to the technical field of platform screen doors, and particularly to a subway platform screen door detection system. Background Art

[0002] With the rapid development of urban infrastructure construction in China, urban rail transit has also been developing rapidly in parallel. In particular, in recent years, the subway construction in large and medium-sized cities in China has developed rapidly. Currently, there are more than twenty cities in China that are building or expanding subway projects. The subway platform screen door (safety door) system can prevent passengers from falling onto the track and causing danger, and reduce human-caused parking delays and train operation accidents.

[0003] During the use of existing subway platform screen doors, some passengers rush in when the screen doors are closing because they are in a hurry to catch the subway. Since the overall structure of the screen doors is hard, when being clamped, it is easy to cause injury to people. Utility Model Content

[0004] The purpose of this utility model is to solve or at least alleviate the problem that during the use of existing subway platform screen doors, some passengers rush in when the screen doors are closing because they are in a hurry to catch the subway. Since the overall structure of the screen doors is hard, when being clamped, it is easy to cause injury to people.

[0005] To achieve the above purpose, the following technical solution is adopted in this utility model:

[0006] A subway platform screen door detection system includes two symmetrically arranged screen door bodies. An anti-pinch component is provided on the screen door body. The anti-pinch component includes two rubber plates arranged on the opposite side walls of the two screen door bodies.

[0007] By adopting the above technical solution, when a passenger breaks in when the screen door body is closing, the rubber plate can reduce the harm of the passenger's collision. When the rubber plate clamps the passenger, the rubber plate will make the sliding rod slide into the sliding hole under the acting force, causing the spring to contract, so as to reduce the clamping force on the passenger, and avoid as much as possible the problem that some passengers rush in when the screen door is closing because they are in a hurry to catch the subway. Since the overall structure of the screen door is hard, when being clamped, it is easy to cause injury to people.

[0008] Optionally, control switches are fixedly connected to the side walls of the sliding holes away from the baffle. Pressure rods are sleeved inside the springs. One end of each pressure rod is fixedly connected to the sliding rod, and the other end of each pressure rod penetrates through the baffle and forms a sliding connection.

[0009] By adopting the above technical solutions, when a passenger is clamped and the spring contracts, the sliding rod will push the pressure rod to move, so that the pressure rod touches the control switch to control the shielding door body, making the shielding door body move in the reverse direction to open the shielding door body and prevent greater harm to the passenger.

[0010] Optionally, a bidirectional electric telescopic rod is installed inside the shielding door body between the two sliding holes. A blocking block is fixedly connected to the output end of the bidirectional electric telescopic rod, and the blocking block is located between the baffle and the control switch.

[0011] By adopting the above technical solutions, when the two rubber plates contact and the shielding door body closes, by starting the bidirectional electric telescopic rod to move the blocking block into the sliding hole, it can prevent the passenger from pushing the rubber plate and making the pressure rod contact the control switch, resulting in the opening of the shielding door body.

[0012] Optionally, connecting rods are fixedly connected to the bottom ends of the opposite side walls of the two shielding door bodies. One end of each connecting rod away from the shielding door body penetrates through the rubber plate and is fixedly connected with a touch switch, and the touch switches are electrically connected to the bidirectional electric telescopic rod respectively.

[0013] By adopting the above technical solutions, when the two rubber plates fit together, the two touch switches will fit together, causing the touch switches to start the bidirectional electric telescopic rod to move the blocking block into the sliding hole. When the two touch switches are separated, the bidirectional electric telescopic rod can be controlled to move the blocking block out of the sliding hole to achieve automatic control.

[0014] Optionally, an alarm lamp is installed at the top of the shielding door body, and the alarm lamp is electrically connected to the control switch.

[0015] By adopting the above technical solutions, when the pressure rod touches and presses the control switch to start the control switch, the control switch can start the alarm lamp to flash, reminding the driver that a passenger is approaching and preventing safety accidents.

[0016] Optionally, a mounting plate is fixedly connected to the bottom end of the alarm lamp. A plurality of first fixing bolts are provided on the mounting plate, and the first fixing bolts all penetrate through the mounting plate and are threadedly connected to the shielding door body.

[0017] By adopting the above technical solutions, the alarm lamp can be conveniently disassembled and replaced through the mounting plate and the first fixing bolts.

[0018] Optionally, both ends of the side wall of the rubber plate close to the sliding rod are fixedly connected with insertion rods, the insertion rods are inserted into the sliding rod, and a plurality of second fixing bolts are arranged on the sliding rod. The second fixing bolts all penetrate through the sliding rod and are threadedly connected with the insertion rods.

[0019] By adopting the above technical solutions, the rubber plate can be conveniently replaced through the insertion rods and the second fixing bolts.

[0020] Optionally, a receiving hole is formed in the sliding rod at the position of the second fixing bolt, and the second fixing bolt is located in the receiving hole.

[0021] By adopting the above technical solutions, the second fixing bolts can be hidden through the receiving holes to prevent the second fixing bolts from extending outside the sliding rod.

[0022] In summary, the beneficial effects of the present application are as follows:

[0023] 1. Through the cooperation of structures such as the sliding rod, the rubber plate and the sliding hole in the present application, when a passenger breaks in when the shielding door body is closed, the rubber plate can reduce the injury caused by the passenger's bump. When the rubber plate clamps the passenger, the rubber plate will cause the sliding rod to slide into the sliding hole under the action of force, causing the spring to contract, so as to reduce the clamping force on the passenger, and try to avoid the situation that passengers rush in when the shielding door is closed because they are in a hurry to catch the subway. Since the overall structure of the shielding door is hard, when being clamped, it is easy to cause damage to personnel.

[0024] 2. When clamping a passenger and the spring contracts, the sliding rod will push the pressure rod to move, so that the pressure rod touches the control switch to control the shielding door body, causing the shielding door body to move in the reverse direction and opening the shielding door body to prevent greater harm to the passenger.
