Figure 1 The lower middle portion shows a schematic diagram of the connection structure of the high-pressure air supply unit 4, and the upper portion shows a partial enlargement of the schematic diagram of the connection structure of the inter-branch purge device 5.

[0039] Specifically, in one or more embodiments of the present invention, the high-pressure air supply unit 4 may include: a high-pressure fan 401 , a pressure relief valve 402 , a main pipeline steel pipe 404 , a diverter 405 , and a rubber hose 406 .

[0040] The bifurcated blowing device 5 may include: a nozzle 502 , a mounting fixture 503 , and a right-angle adapter 504 .

The air outlet of the high-pressure fan 401 is connected to the main pipeline steel pipe 404 through the pressure relief valve 402. The pressure relief valve 402 can adjust the pressure of the fan. When the pressure in the fan exceeds the set pressure value, the pressure relief valve 402 will open quickly and release the excess pressure through the wind flow, thereby protecting the high-pressure fan 401 from damage.

[0042] The main pipeline steel pipe 404 is at least partially laid parallel to the railway turnout, and the parallel laying part has multiple holes and is provided with a diverter 405, and the output pipe opening of the diverter 405 is connected to a rubber hose 406. Compared with the steel pipe, the rubber hose 406 has good flexibility and elasticity and is easy to install.

[0043] The switch blowing device 5 is a main snow removal device, which is installed in the middle position of the two sleepers below the middle of the point rail and the base rail. The rubber hose 406 passes through the bottom of the rail of the railway switch and is fixed under the rail through the installation fixture 503 in the switch blowing device 5. The bottom is connected to the nozzle 502 through the right-angle adapter 504, so that the nozzle 502 is between the point rail and the base rail of the railway switch, and the direction of the nozzle 502 is the same as the direction of the rail of the railway switch.

[0044] The high-pressure fan 401 outputs air flow to release pressure through the pressure relief valve 402.

One end of the vertical pipe is connected to the air outlet of the high-pressure fan 401 through the pressure relief valve 402, and the other end is connected to the horizontal pipe; the air outlet valve 403 is set in the vertical pipe. The horizontal pipe is laid parallel to the railway turnout, which is convenient for conveying wind power to the corresponding turnout area; and the horizontal pipe has multiple openings and a diverter 405 is set.

[0047] Furthermore, in one or more embodiments of the present invention, the diverter head 405 is a one-inlet and two-outlet type diverter head, and in order to increase the wind pressure, the ratio of the output pipe diameter to the input pipe diameter of the diverter head 405 is 2:1; the output pipe mouth of the diverter head 405 is respectively connected to two rubber hoses 406.

[0048] Furthermore, in one or more embodiments of the present invention, the nozzle 502 is a detachable stainless steel duckbill streamlined nozzle, which can increase the wind outlet area while increasing the wind speed, reducing the wind outlet resistance and improving the snow removal efficiency. The two rubber hoses 406 are respectively connected to the two nozzles 502 via the right-angle adapter 504, and the two nozzles 502 are installed at 180 degrees based on the two right-angle adapters 504 with the nozzles facing outward.

[0049] That is, two sets of nozzles 502 are installed parallel to the rails of the railway turnout, facing different directions of the rails, and fixed under the base rails by means of the installation fixtures 503. This design does not affect the operation of the turnout, and can be opened at any time according to the temperature on snowy days, and snow can be removed during the snowing process to prevent poor snow removal effect when the snow on the turnout is too thick; the nozzles 502 are detachable, which is convenient for routine maintenance and replacement.

[0052] The control base station 2 within the station is used to issue snow removal control instructions to the switch snow removal control cabinet 3, and to receive the working data reported by the switch snow removal control cabinet 3 and upload it to the remote monitoring center 1; it mainly realizes the centralized monitoring and control of the switch snow removal control cabinet 3 within the station, and has remote operation, data recording, fault query, and emergency operation.

[0053] The remote monitoring center 1 is used to monitor the working data of each turnout snow removal control cabinet through the station control base station 2. The working data may include the working status of the control cabinet, turnout temperature, ambient temperature, voltage, current and fault alarm information.

[0054] The rail temperature monitoring unit 6 is used to monitor the rail temperature of the railway turnout and transmit the rail temperature back to the turnout snow removal control cabinet 3; the environment monitoring unit 7 is used to detect the environment temperature and transmit the environment temperature back to the turnout snow removal control cabinet 3.

[0055] The turnout snow removal control cabinet 3 is used to respond to the snow removal control command issued by the station control base station 2 or control the railway turnout snow removal device to start / stop snow removal when it is determined that the railway turnout snow removal needs to be turned on / off according to the rail temperature and ambient temperature. It can also be used to report system work logs and equipment failure alarm information to the station control base station 2.
