[0002] Foreign object intrusion detection devices are core monitoring equipment for ensuring the safe operation of rail transit systems such as railways and subways. They use sensors such as lidar, cameras, and millimeter-wave radar to scan the track line and surrounding safety clearance area in real time, accurately identify and capture various foreign objects that intrude into the area. The device quickly transmits the detected foreign object signal to the control center, triggering an alarm simultaneously. Some high-end devices can also be linked with the train operation control system to automatically send deceleration or stopping commands to approaching trains, preventing traffic accidents caused by collisions between foreign objects and trains from the source, while reducing the pressure of manual inspections and ensuring the continuity and safety of rail transit operations.

A frame 201, the main frame 201 of the placement mechanism 2, is provided to fix the first servo motor 202, support the detection component 207 and related components. The first servo motor 202, a power source, drives the threaded rod 203 to rotate, providing power for the movement of the baffle plate 205 and the cleaning plate 206. The threaded rod 203, a transmission component, is used to... Driven by the motor 202, the screw-driven adjusting block 204 moves back and forth.

The shielding plate 205, a protective component, can move back and forth in front of the detection component 207 to block dust and foreign objects when the train passes, preventing damage or obstruction to the detection lens. The cleaning plate 206, a cleaning component, wipes the lens surface of the detection component 207 as it moves with the shielding plate 205, removing dust and ensuring detection effectiveness. The detection component 207, the core detection structure, is responsible for scanning the track and surrounding area in real time to identify foreign object intrusion.

[0031] Specifically, such as Figure 3 As shown, the detection component 207 includes a cavity 2071, and a plurality of three-dimensional detection device bodies 2072 are movably connected inside the cavity 2071. A connecting plate 2073 is fixedly connected to the top of the plurality of three-dimensional detection device bodies 2072.

A sliding block 105 is threadedly connected to the surface of the screw rod 104. The screw rod 104 is fixedly connected to the bottom of the second servo motor 102.

[0036] Specifically, such as Figure 4 As shown, the sliding block 105 is fixedly connected to the right side of the frame 201, and two rain shields 106 are fixedly connected to the inner side of the gantry frame 101.

[0037] In this embodiment: A gantry frame 101 is set up, and the main frame 201 of the adjustable component 1 is used to fix the second servo motor 102. Sliding grooves 103 and 3 are provided, serving as the mounting base for the entire device. The second servo motor 102, a height-adjustable power source, drives the screw rod 104 to rotate, providing power for the lifting and lowering of the placement mechanism 2. The sliding groove 103 guides and provides installation space, offering installation positions for the screw rod 104 and the sliding block 105, and restricting the movement trajectory of the sliding block 105. A screw rod 104, a transmission component, is set up and rotates under the drive of the second servo motor 102. Through a threaded engagement, it drives the sliding block 105 to move up and down. The sliding block 105 is connected to the transmission component, with one end threaded to the screw rod 104 and the other end fixed to the frame 201. The rotation of the screw rod 104 is converted into the lifting and lowering motion of the frame 201.

[0040] In this embodiment: by setting a slide groove 3 and a slider 4, the slider 4 and the inner wall of the slide groove 3 are movably connected, the height of the auxiliary frame 201 is adjusted on the inner wall of the gantry frame 101, and by setting a slide rod 5, the guide auxiliary component is fixed on the inner wall of the slide groove 3, and the slider 4 slides along the surface of the slide rod 5, which further enhances the stability of the placement mechanism 2 when it is raised and lowered.

[0041] Specifically, such as Figure 4 As shown, a hidden groove 6 is provided at the bottom of the gantry frame 101, and the frame 201 is movably connected to the inner wall of the hidden groove 6.

[0042] Specifically, such as Figure 3 As shown, the surface of the protective cover 2075 is fitted with a corrosion-resistant cover 7, which is made of stainless steel.

[0043] In this embodiment: by setting a hidden slot 6, the bottom of the gantry 101 can be partially embedded in the hidden slot 6 when the placement mechanism 2 is lowered, so as to achieve compact storage of the device or adapt to low-height scenarios. By setting a corrosion-resistant cover 7, a protective reinforcement component, which is sleeved on the surface of the protective cover 2075, the material is stainless steel, which has corrosion resistance, further protecting the protective cover 2075 and the internal electric telescopic rod 2074, and adapting to harsh outdoor environments.

[0044] Working principle: First, the detection height is adapted by adjusting component 1. The second servo motor 102 inside the gantry 101 drives the screw rod 104 to rotate. The screw rod 104 drives the sliding block 105 to move up and down along the sliding groove 103 through threaded engagement. At the same time, the slider 4 on the left side of the frame 201 slides synchronously along the sliding rod 5 in the sliding groove 3, driving the placement mechanism 2 to rise and fall smoothly. When descending, the frame 201 can be partially embedded in the hidden groove 6 for storage. The rain shield 106 prevents rainwater erosion. During the detection stage, the electric telescopic rod 2074 drives the connecting plate 2073 to move the three-dimensional detection device body 2072 within the cavity 2071. Once adjusted to a suitable height, the track and surrounding area are scanned in real time using 3D scanning technology to identify foreign object intrusion. When a train is about to pass, the first servo motor 202 starts and drives the threaded rod 203 to rotate. The adjusting block 204 drives the shield 205 to move in front of the detection component 207 to block dust and foreign objects, preventing damage or obstruction to the lens. After the train passes, the shield 205 is reset, and the cleaning plate 206 on its top simultaneously wipes and removes dust from the lens surface to ensure detection clarity. Meanwhile, the stainless steel corrosion-resistant cover 7 outside the protective cover 2075 continuously protects the electric telescopic rod 2074, ensuring stable operation of the device in harsh outdoor environments.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
