[0002] With the rapid development of urbanization, the role of urban rail transit in daily travel is becoming increasingly significant. Rail transit is generally operated in underground or tunnel environments with poor light. When a rail vehicle enters a station, it is necessary to pre-measure the distance to the station and then stop accurately to ensure that the door of the rail vehicle can correspond to the entrance and exit of the station to facilitate passengers getting on and off the vehicle. Because it is underground, the positioning signal of the positioning system is poor, and it is generally necessary to use external distance measurement or prompting devices to provide accurate distance positioning for the driver of the rail vehicle;
[0003] The existing distance measuring or prompting device for positioning generally sets corresponding distance signs on both sides of the tunnel away from the station. When the rail vehicle is away from the sign, the vehicle lights are used to cooperate with the sign to make it reflective, so as to remind the rail vehicle driver of the positioning distance. This method can intuitively provide the driver with an effective sense of distance; however, in actual use, it is inevitable that the rail vehicle lights will fail. Once this happens, the function of the prompt sign cannot be exerted, affecting the normal positioning of the vehicle;
[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a rapid positioning device for urban rail vehicles. Utility Model Content

Intuitive positioning guidance. At the same time, a group of wind lighting devices are installed in the upper part of the tunnel on one side of each sign bin. The wind lighting device includes lighting lamps distributed in the direction of the sign bin. A wind turbine is arranged on one side of the lighting lamp. When the wind turbine is affected by the air flow caused by the passing rail vehicles, it drives the internal wind power generation system to operate, thereby generating electricity, thereby providing electricity for the operation of the lighting lamps. That is, the operation of the lighting lamps does not require the help of additional electricity functions, and wind energy is utilized under the action of the wind turbines, which ensures that when the rail vehicle lights fail or the power system inside the tunnel fails, the wind turbine can still be used to illuminate the reflective signs inside the sign bin, thereby playing a safe and timely response positioning function.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0018] See also Figure 1-Figure 3The rapid positioning device for urban rail vehicles includes a tunnel 10 and a track 11; the track 11 is arranged at the bottom of the tunnel 10, and a prompt type positioning mechanism is installed at intervals on the inner wall of the tunnel 10 according to the requirement of the prompt distance. The prompt type positioning mechanism provides accurate distance guidance for the rail vehicle driver, so that the driver can accurately park the vehicle at the station. The prompt type positioning mechanism includes a distance indicator 12 fixedly installed by a plurality of mounting brackets 13, and the end of the mounting bracket 13 away from the distance indicator 12 is fixed on the inner wall of the tunnel 10. The mounting bracket 13 is provided with an indicator card compartment 17 on the side facing the movement of the rail vehicle. A reflective indicator mark is arranged on the inner wall of the indicator card compartment 17. The reflective indicator mark reflects when it is illuminated by the light of the rail vehicle, so as to provide intuitive positioning guidance for the driver. At the same time, at each indicator card compartment 17, a reflective indicator mark is provided on the inner wall of the indicator card compartment 17. A group of wind power lighting devices 14 are installed in the upper part of the interior of the tunnel 10 on one side of the sign bin 17. The wind power lighting device 14 includes a lighting lamp 16 distributed toward the sign bin 17. A wind turbine 15 is arranged on one side of the lighting lamp 16. When the wind turbine 15 is affected by the air flow caused by the passing rail vehicle, it drives the internal wind power generation system to operate, thereby generating electrical energy, thereby providing electrical energy for the operation of the lighting lamp 16. That is, the operation of the lighting lamp 16 does not require the help of additional electrical energy functions, and wind energy is utilized under the action of the wind turbine 15, that is, when the rail vehicle lights fail, or the power system inside the tunnel 10 fails, the wind turbine 15 can still be used to illuminate the reflective indicator signs inside the sign bin 17, that is, it plays a safe and timely response positioning function.
[0019] In the embodiment of the present invention, the illuminating lamp 16 can be a spotlight, which takes advantage of the long range and strong focusing of the spotlight to ensure that the reflective indicator sign in the sign bin 17 is accurately illuminated. At the same time, a fixed base is installed at the non-illuminating end of the illuminating lamp 16, and the illuminating lamp 16 is swingably connected to the fixed base, that is, the output light angle of the illuminating lamp 16 is adjusted according to the height of the distance to the sign 12, so as to ensure the reflection accuracy of the reflective indicator sign in the sign bin 17. At the same time, a power storage box is arranged in the fixed base, and the power storage box is electrically connected to the wind turbine 15, that is, the electric energy generated by the wind turbine 15 driven by wind is stored in the power storage box for use by the illuminating lamp 16 when a fault occurs;
[0020] Reflective indicator signs are generally designed as distance numbers, that is, the exact distance from the vehicle, to provide accurate position guidance for rail vehicle drivers when they stop at the station.
[0021] In one embodiment of the present invention, in order to prevent the outer side of the sign bin 17 from being covered by dust and affecting its reflection due to being placed outside the rail vehicle for a long time, a group of self-driving cleaning mechanisms are arranged on the outer side of the sign bin 17 for transverse movement. The self-driving cleaning mechanisms move transversely along the reflective prompt mark on the sign bin 17 to clean the dust on its surface to ensure that its surface is clean.
[0022] See also Figure 4 , Figure 5 The self-driving cleaning mechanism includes a power base 19 fixedly installed at the bottom of the distance indicator 12. A horizontal lead screw 22 is rotatably arranged on one side of the power base 19. One end of the lead screw 22 is connected to a servo motor fixed inside the power base 19, and the other end is rotatably connected to the inner wall of the power base 19 through a bearing. A nut 21 is threadedly connected to the lead screw 22. A guide device for limiting its rotation is arranged on the nut 21. A connecting rod 23 is connected to the top of the nut 21. The connecting rod 23 movably passes through a slot opened between the power base 19 and the indicator bin. The top of the connecting rod 23 extends to the bottom of the indicator card bin 17 and is installed with a brush rod bottom plate 24. The top of the brush rod bottom plate 24 is installed with a cleaning brush rod 20. The top of the cleaning brush rod 20 extends to the top of the indicator card bin 17. That is, the servo motor is started to drive the lead screw 22 to rotate, and then the nut 21 is driven to move back and forth along the lead screw 22. Then, under the connection of the connecting rod 23 and the brush rod bottom plate 24, the cleaning brush rod 20 is controlled to clean the reflective prompt mark on the indicator card bin 17, so as to realize the function of automatic regular cleaning;
[0023] When the cleaning brush rod 20 is not in use, it stays at one side of the interior of the indicator card compartment 17, that is, placed at one side of the reflective indicator mark, and is in a position where the reflective indicator mark is not blocked.
[0024] The working principle of the utility model is: in the idle part of the device, all the driving parts mentioned above, which refer to power elements, electrical components and adapted power supplies, are connected through wires, and the electrical components are electrically connected in a sequential working order. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. Before use during installation, a combination of multiple distance indicators 12 and wind lighting devices 14 is installed at the corresponding position in advance according to the requirements of the positioning distance, and then the corresponding distance reflective indicator marks are installed on the indicator bin 17, so that it can reflect itself when encountering the lights of the rail vehicle to provide positioning guidance for the driver. At the same time, when the wind turbine 15 is driven by the air flow driven by the rail vehicle, the internal wind power generation system operates to generate electricity, and then the electric energy is stored in the power storage box. When the rail vehicle lights encounter a fault, the lighting lamp 16 is started to operate so that the light it generates illuminates the indicator bin 17, thereby providing positioning guidance for the rail vehicle driver. At the same time, the servo motor is regularly started to drive the cleaning brush rod 20 to move along the outside of the indicator bin 17 to clean the outside of the indicator bin 17 to maintain the accuracy of reflection.
[0025] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
