Embodiment Construction
[0025] Such as figure 1 As shown, the drain cover device of the present invention is formed by connecting a plurality of cover units, and each cover unit includes a cover 1, wheels 2, lighting lamps 3, LED indicator lights 4, water passage holes 5, and nameplates 6 , upper pin 7, lower pin 8, groove handle 9, shock absorber 10, reserved bolt hole 11, lithium battery 12, air pressure sensor 13, steel wire filter 14, water flow counter 15, signal transmitter 16, infrared measuring Distance sensor 17, damping sleeve 18, bolt 19, compression spring 20, damping pad cover 21, sealing coil 22, drainage gap 23, "V" shape track 24 and induction switch 25.
[0026] The "V"-shaped track 24 on both sides of the drain is reserved during the construction of the drain. Wheels 2 are arranged around the bottom of the cover plate 1. The wheel is butterfly-shaped and has a diameter of 2 cm. Fit, the depth of the track is 0.8cm, and there is a drainage gap pointing to the side of the ditch every...

The invention discloses a drainage ditch cover plate device used for a high-speed railway tunnel. The drainage ditch cover plate device used for the high-speed railway tunnel comprises a plurality ofcover plate units. Each cover plate unit comprises a cover plate, a wheel, a shock absorber, an air pressure sensor, a signal emitter, an indicator lamp, an infrared distance-measuring sensor, and a rail matched with the wheel, wherein the cover plate is connected with the wheel through the shock absorber, the indicator lamp is located on the upper surface of the cover plate, the color of the indicator lamp is controlled by the infrared distance-measuring sensor located at the bottom of the cover plate, and the air pressure sensor is located at the bottom of the cover plate and is connected with the signal emitter to monitor an air pressure change in a drainage ditch; and the cover plate is provided with a plurality of through holes provided with filter screens, and water flow meters connected with the signal emitter are mounted at the bottoms of the through holes. By the adoption of the drainage ditch cover plate device, the problem that when a high-speed train passes through the tunnel, the cover plates vibrate under the aerodynamic effect and are broken, and consequentially, the traffic safety is affected by fragments flying when the high-speed train passes through the tunnel again is solved; and the water accumulation condition in the tunnel and the state of the tunnel when the high-speed train passes through the tunnel can be remotely monitored even if monitoring personnelis not located on the scene, and the application range is wide.
Description
technical field [0001] The invention relates to tunnel drains in road engineering construction auxiliary facilities, in particular to a drain cover device for high-speed railway tunnels. Background technique [0002] At present, the drain covers in high-speed railway tunnels are all prefabricated concrete covers, which are heavy and have poor corrosion resistance. Workers are prone to breakage during maintenance and flipping, and it is difficult to lift the whole. At the same time, when a train passes through a high-speed railway tunnel at high speed, due to the aerodynamic effect, the pressure in the tunnel changes sharply, and a large negative pressure appears in the drain, which will cause the drain cover to lift and vibrate to make noise, affecting the comfort of passengers in the train. Plates are prone to chipping, reducing service life. Especially when the high-speed rail enters the tunnel again at a higher speed, the negative pressure in the ditch is huge, and the b...
