[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0038] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0039] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a platform area train obstacle autonomous sensing device.

[0040] Example 1:

[0041] Combination Figures 1-6 As shown, this utility model provides an autonomous train obstacle sensing device for a platform area, including an obstacle fall prevention mechanism 100, four infrared detectors 200 installed on the obstacle fall prevention mechanism 100, multiple anti-collision bars 300 installed within the obstacle fall prevention mechanism 100, and an autonomous power supply mechanism 400 installed on the obstacle fall prevention mechanism 100. The obstacle fall prevention mechanism 100 is located at the edge of the platform ground and is used to provide a support platform for the overturning of the anti-collision bars 300. The infrared detectors 200 are installed on the obstacle fall prevention mechanism 100 to detect obstacles near the edge of the platform. The autonomous power supply mechanism 400 is used to provide lateral overturning kinetic energy to the multiple sets of anti-collision bars 300 evenly distributed at the edge of the platform.

[0042] The obstacle fall prevention mechanism 100 includes two sets of bases 110, two limiting pads 120 disposed within the two sets of bases 110, two pins 170 installed within the two sets of bases 110, and two load-bearing cantilever arms 180 disposed outside the pins 170.

[0043] The top and bottom of the load-bearing cantilever 180 are provided with semi-circular grooves, and a guide rod is provided in the semi-circular groove at the top of the load-bearing cantilever 180, while a cable 190 is connected to the inner wall of the semi-circular groove at the bottom of the load-bearing cantilever 180.

[0044] The outer end of the limiting pad 120 has two symmetrically distributed vertical grooves, and a horizontal bar 150 is installed in the vertical groove;

[0045] A tension spring 160 is connected to the crossbar 150 and the guide rod;

[0046] Two adjacent infrared detectors 200 are positioned outside two of the bases 110;

[0047] Multiple anti-collision bars 300 are installed within two of the load-bearing cantilever arms 180.

[0048] The self-powered mechanism 400 includes a housing 410 and a drive rod 480. A motor 420 is installed inside the housing 410, and two sets of clamps 430 are installed inside the limit pad 120.

[0049] A first drive wheel is mounted on the internal transmission shaft of the motor 420, and a second drive wheel is mounted on the outer end of the drive rod 480. A track 490 is connected to the first drive wheel and the second drive wheel.

[0050] There are four clamps 430, and bearings 440 are installed inside the clamps 430;

[0051] A take-up roller 450 is provided in each of two adjacent clamps 430, and the column heads at both ends of the take-up roller 450 respectively penetrate into two of the bearings 440;

[0052] The inside of the take-up roller 450 is provided with a cross-shaped hole, and a linkage rod 460 is provided between two adjacent take-up rollers 450;

[0053] Furthermore, two of the take-up rollers 450 are equipped with drive rods 470, which are located on the outside of the pad 140.

[0054] When passengers pass by on the platform and drop trash or other obstacles, the moment the obstacle moves to the edge of the platform ground due to the airflow, the infrared detector 200 detects the obstacle and sends a signal to the terminal, which eventually starts the motor 420. As the motor 420 drives the track 490 to rotate, the drive rod 480, take-up roller 450, linkage shaft 460 and transmission rod 470 that form a linkage structure can be driven. At this time, the multiple evenly distributed cables 190 will be wound and tightened by the take-up roller 450 until the bearing cantilever 180 drives the multiple anti-collision bars 300 to flip upward and form a guardrail structure.

[0055] The moment an obstacle is detected, the terminal will display the obstacle's exact location on the screen and pre-tighten the platform area for staff, thereby preventing the obstacle from accidentally falling into the tracks due to airflow.

[0056] Example 2:

[0057] Combination Figures 4-6 As shown, based on Embodiment 1, symmetrical slots are provided in the middle of the inner ends of the base 110 and the limiting pad 120, and a horizontal cover plate 130 is provided in the slot.

[0058] Two of the bases 110 have pads 140 inside, and the top surface of the pads 140 is flush with the ground.

[0059] The top of the base 110 has evenly distributed arc-shaped slots;

[0060] The cantilever 180 has evenly distributed horizontal holes inside, and the horizontal holes are adapted to be symmetrical with the arc-shaped slot.

[0061] Preferably, both the base 110 and the limiting pad 120 are made of stainless steel, and the surfaces of the base 110 and the limiting pad 120 are coated with an insulating paint layer. Depending on the assembly requirements of the groove on the platform edge, the base 110 can be fixed with concrete or expansion bolts.

[0062] The pad 140 is located directly below the multiple anti-collision bars 300. When the multiple anti-collision bars 300 are pulled back to their original position directly above the ground by the two load-bearing cantilever arms 180, the pad 140 can provide a certain compressive support for the horizontally placed multiple anti-collision bars 300 to improve the stability of the multiple anti-collision bars 300 in the reset state.

[0063] Example 3:

[0064] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, the cover plate 130 is made of stainless steel, and two symmetrically distributed limiting holes are provided at both ends of the cover plate 130.

[0065] The 190 cable is fitted through the limiting hole.

[0066] Preferably, the cable 190 is made of multiple strands of steel wire wound together. With the help of the tension spring 160, the load-bearing cantilever 180 is subjected to a restoring traction force. When the infrared detector 200 detects an obstacle, the rapidly wound cable 190 can quickly lift the load-bearing cantilever 180 and multiple anti-collision bars 300 upwards. This can then push the obstacle affected by the airflow toward the ground inside the platform. While effectively blocking the accumulated obstacles, it can also prevent some elastic obstacles from accidentally falling into the rails due to the high ejection height.

[0067] The working principle and usage process of this utility model: Pre-installed grooves are opened on both sides of the platform foundation ground. Then, the two combined bases 110 and tension springs 160 are installed in the pre-installed grooves on the ground. Two infrared detectors 200 are installed on the outside of the two bases 110 respectively. At this time, the top of the infrared detectors 200 extends above the ground, and the detection ends of the two adjacent infrared detectors 200 are symmetrical in the horizontal direction.

[0068] Next, multiple anti-collision bars 300 are fitted and installed in the two adjacent load-bearing cantilever arms 180;

[0069] When debris or foreign objects appear on the platform floor due to human or natural airflow factors, as the debris or foreign objects move towards the edge of the platform floor, the moment the infrared detector 200 contacts and detects the debris or foreign objects, the motor 420, which is activated by the signal, will drive the track 490. At this time, the drive rod 480, the take-up roller 450, the linkage rod 460, and the transmission rod 470 will be driven. The multiple take-up rollers 450, which are effectively assembled at this time, will take up the cable 190. As the cable 190 continues to tighten, the load-bearing cantilever 180 will drive the multiple anti-collision bars 300 to flip upward from the inside of the limiting pad 120 until the load-bearing cantilever 180 and the multiple anti-collision bars 300 form a semi-circular shielding structure based on the base 110 and the limiting pad 120. At this time, the edge of the platform floor can effectively block obstacles such as debris, and the precise location of the debris or foreign objects will be displayed from the cloud via the signal. At this time, the staff on the platform can quickly clear the obstacles in time.

[0070] Once the obstacle is cleared, the load-bearing cantilever 180 and multiple anti-collision bars 300 will retract back into the inner side of the limiting pad 120.

[0071] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
