Technical Field
[0001] This utility model relates to the field of railway track equipment technology, specifically to a spray system that intelligently cools the track based on the locked track temperature. Background Technology
[0002] In high-temperature environments, railway rails are prone to deformation due to thermal expansion, affecting train operation safety. Existing rail cooling methods suffer from low automation and poor cooling effects, making it difficult to accurately control rail temperature. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a spray system that intelligently cools the rails based on the track temperature. This spray system monitors the temperature by placing magnetic temperature sensors on the side of the rails and arranging spray pipes longitudinally along the rails with several spray nozzles spaced apart, so that the spray equipment can be automatically activated to cool the rails when the rail temperature exceeds a threshold.
[0004] The objective of this utility model is achieved through the following technical solution: A spray system for intelligent cooling based on the track temperature of a railway is disclosed. The spray system includes a water storage pumping mechanism, a spray pipe, and several spray nozzles. The spray pipe is attached to the side of the rail and arranged longitudinally along the rail. The spray pipe is fixed to the rail fastener by cable ties. The spray nozzles are spaced apart on the spray pipe. The water storage pumping mechanism is connected to the inlet of the spray pipe to pump water.
[0005] The water storage pumping mechanism includes a water storage tank, a water pump, and a pressure tank connected in sequence via a pipe body, and a pressure control valve is provided at the outlet end of the pressure tank.
[0006] Several magnetic temperature sensors are spaced apart on the side of the rail. The magnetic temperature sensors are connected to the temperature control box via cables. The temperature control box is also connected to the pressure control valve via cables.
[0007] The rails are laid on concrete sleepers and secured by the rail fasteners.
[0008] The advantages of this utility model are: Precise cooling: Accurately collects temperature data and automatically controls the start and stop of the spray system to prevent thermal expansion and deformation of the rails; Stable and reliable: Ensures stable water pressure and uniform spraying from the nozzles. Based on the existing railway structure, it has high stability and is easy to install and maintain. Energy-efficient and efficient: Spraying only starts when the rail temperature exceeds the limit, saving resources and improving efficiency; Convenient installation and maintenance: The connection and fixing method of the spray water pipe simplifies the installation process, making it easy to quickly disassemble and replace parts; Water level stability is ensured: the water storage tank is equipped with a level gauge to monitor the water level in real time and to replenish water in a timely manner in conjunction with the water replenishment device.

[0010] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art: Example: Figure 1 , 2 As shown, this embodiment specifically relates to a spray system for intelligent cooling based on the track temperature of a railway. The spray system includes a water pumping mechanism, a temperature measuring mechanism, a spray water pipe 2, and several spray nozzles 3.
[0011] like Figure 1 , 2 As shown, the water storage and pumping mechanism is arranged on one side of the railway subgrade 6. Concrete sleepers 1 are arranged longitudinally at intervals, and steel rails 5 are arranged on the concrete sleepers 1 and fastened by rail fasteners 14. The water storage and pumping mechanism includes a water storage tank 13, a water pump 12, and a pressure tank 11. The water storage tank 13 stores clean water for pumping and is equipped with a level gauge for water level monitoring to facilitate timely water replenishment. The water storage tank 13, water pump 12, and pressure tank 11 are connected by a pipe. The water pump 12 pumps water from the water storage tank 13 to the pressure tank 11. The pressure tank 11 uses the compressibility of air inside the tank to regulate and store water volume and maintain the required pressure. A pressure control valve 11 is installed at the outlet of the pressure tank 11 to regulate the pressure inside the pressure tank 11 and control the opening and closing of the outlet.
[0012] like Figure 1 ,2 As shown, the temperature measuring mechanism includes magnetic temperature sensors 4 and a temperature control box 8. Several magnetic temperature sensors 4 are arranged at equal intervals along the longitudinal direction on the outer surface of the rail 5 and fixed magnetically. Each magnetic temperature sensor 4 is connected to the temperature control box 8 via a cable 9. It should be noted that the pressure control valve 11 is also connected to the temperature control box 8 via a cable 9. The magnetic temperature sensors 4 are used to monitor the temperature of the rail 5 in real time and transmit the temperature monitoring data back to the temperature control box 8 for processing and analysis. It should be noted that both the temperature measuring mechanism and the water pumping mechanism in this embodiment are powered by a power supply 7, which can be mains power or an energy storage device.
[0013] like Figure 1 , 2 As shown, the inlet of the spray pipe 2 is connected to the water storage pump mechanism, specifically the pressure control valve 11 on the outlet of the pressure tank 11. The spray pipe 2 is attached to the side of the rail 5 and arranged longitudinally along the rail 5. The spray pipe 2 and the rail fastener 14 of the rail 5 are connected and fixed by cable ties 15, that is, the cable ties 15 bind the spray pipe 2 and the rail fastener 14 together for positioning. The spray nozzles 3 are distributed at intervals on the spray pipe 2, specifically, as shown in the figure. Figure 3 As shown, the sprinkler head 3 includes a tee 3a and a nozzle 3b. The nozzle 3b is located at one port of the tee 3a, and the other two ports of the tee 3a are respectively connected to sections of the sprinkler water pipe 2. It should be noted that the sprinkler water pipe 2 is made of high-pressure explosion-proof PE pipe.
[0014] like Figure 1 , 2 As shown in Figure 3, the specific working method of the sprinkler system in this embodiment includes the following steps: S1: The temperature of each area of the rail 5 is collected by each magnetic temperature sensor 4 and transmitted back to the temperature control box 8 for analysis. If the rail temperature of the rail 5 is within the rail temperature locking range, the magnetic temperature sensors 4 are controlled to perform real-time monitoring. The analysis refers to determining which magnetic temperature sensors 4 are monitoring temperatures that exceed the preset temperature threshold. For example, the rail temperature of the Longhai Railway is locked at 43.5°C in summer. The monitoring stops when the temperature is below 30°C and when it is above the locked rail temperature.
[0015] S2: When the magnetic temperature sensor 4 detects that the rail 5 exceeds the preset temperature threshold, the temperature control box 8 controls the pressure control valve 11 to open the water outlet of the pressure tank 11 to pump clean water into the spray pipe 2, and spray atomized water outward through the spray nozzle 3 to quickly cool the rail 5.
[0016] S3: When the magnetic temperature sensor 4 detects that the temperature of the rail 5 has dropped below the preset temperature threshold, the temperature control box 8 controls the pressure control valve 11 to close the water outlet of the pressure tank 11 and stop the atomized water spraying for cooling.
[0017] The beneficial effects of this embodiment are as follows: Precise cooling: Accurately collects temperature data and automatically controls the start and stop of the spray system to prevent thermal expansion and deformation of the rails; Stable and reliable: Ensures stable water pressure and uniform spraying from the nozzles. Based on the existing railway structure, it has high stability and is easy to install and maintain. Energy-efficient and efficient: Spraying only starts when the rail temperature exceeds the limit, saving resources and improving efficiency; Convenient installation and maintenance: The connection and fixing method of the spray water pipe simplifies the installation process, making it easy to quickly disassemble and replace parts; Water level stability is ensured: the water storage tank is equipped with a level gauge to monitor the water level in real time and to replenish water in a timely manner in conjunction with the water replenishment device.
