Embodiment Construction
[0007] Such as figure 1 , as shown, the structure of the device is composed of a brine tank 1, a connecting pipe 2, a delivery pump 3, a pressure regulating valve 4, a return pipe 5, a delivery pipe 6, a liquid outlet pipe 7 and a fixed card 8. The brine tank 1 is a container for brine, which is arranged above the tunnel entrance. The delivery pump 3 is the power equipment for delivering brine, and is installed near the brine tank 1. The delivery pump 3 is a special pump with anti-corrosion function for brine. To prolong the service life of the pump, a connecting pipe 2 is provided between the brine tank 1 and the delivery pump 3, and the two ends of the connecting pipe 2 are respectively fixed and sealed with the liquid outlet of the brine tank 1 and the liquid inlet of the delivery pump 3. The delivery pipe 6 is connected to the liquid outlet of the delivery pump 3, and the delivery pipe 6 is laid with an anti-corrosion plastic pipe. When the delivery pipe 6 is laid, it is f...

The invention discloses a brine deicing device of railway tunnels, wherein the brine is calcium chloride brine below a saturation level, and the brine deicing device consists of a brine tank, a connecting pipe, a delivery pump, a pressure regulating valve, a return pipe, a delivery pipe, a liquid outlet pipe and a fixing clip. The brine tank is arranged over one side of a tunnel opening, the delivery pump is arranged near the brine tank, the connecting pipe is provided between the brine tank and the delivery pump, the liquid outlet of the delivery pump is connected with the delivery pipe, the pressure regulating valve is connected on the delivery pipe, the return pipe is connected on the pressure regulating valve, the liquid outlet pipe is connected on the delivery pipe, and the liquid outlet pipe is installed on the wall of the tunnel by the fixing clip. According to the brine deicing device of the invention, the effluent water droplets are salinized by the brine in the liquid outlet pipe to lose the freezing function and flow onto the ground along the outer wall of the liquid outlet pipe.
Description
technical field [0001] The utility model relates to a salt water deicing device for a railway tunnel, which belongs to the field of railway transportation. Background technique [0002] Tunnels running through my country's railways have the characteristics of leakage and dripping. In cold regions, these dripping water form popsicles hanging on the top wall of the tunnel every winter, which can easily cause breakdown and discharge of the bare power transmission lines below. , bringing great danger to railway transportation. At present, manual beating is generally used to remove ice sticks. For example, Qinling Tunnel has special ice workers to carry out deicing operations every year. Their working environment is difficult, dangerous, and deicing costs are high. This primitive deicing method is no longer suitable for modernization. The need for railway construction. Contents of the invention [0003] The purpose of the present invention is to design a kind of salt water dei...
