DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-3 The ambient temperature control device in the subway tunnel includes a mounting base 1, on the top surface of which a pumping box 2 and a pressure cylinder 3 are fixedly mounted. The pumping box 2 is connected to a water inlet pipe 4, and the other end of the water inlet pipe 4 is connected to an external water source. The pumping box 2 is connected to a water outlet pipe 5, and the other end of the water outlet pipe 5 is connected to the pressure cylinder 3. A one-way valve is installed in both the water inlet pipe 4 and the water outlet pipe 5. A reciprocating screw 6 is rotatably connected to the pumping box 2, and an impeller 7 is installed at one end of the reciprocating screw 6. The impeller 7 includes a plurality of blades, each of which is connected to the outer surface of the water source. One end of each blade is provided with an air slot, which can further absorb the impact of wind, thereby increasing the rotation rate of the impeller 7. When the subway passes through the tunnel, wind is generated, which drives the impeller 7 to rotate, and then drives the pumping mechanism on the reciprocating screw 6. At the same time, the setting of the one-way valve fixes the direction of water flow in the water inlet pipe 4 and the water outlet pipe 5, so that the water inlet pipe 4 only receives water from the outside and flows into the pumping box 2, and the water outlet pipe 5 only receives water from the pumping box 2 and flows into the pressure cylinder 3;

[0024] A pumping mechanism is provided on the reciprocating screw 6, and the pumping mechanism is powered by the rotation of the reciprocating screw 6. The pumping mechanism includes a screw sleeve 10, and the screw sleeve 10 is threadedly connected to the reciprocating screw 6. A baffle 13 is fixedly installed at the bottom end of the reciprocating screw 6 to prevent the screw sleeve 10 from separating from the reciprocating screw 6. A plurality of connecting rods 11 are fixedly installed on the bottom surface of the screw sleeve 10. The length of each connecting rod 11 is equal to the length of the reciprocating screw 6 extending in the pumping box 2, further increasing the sliding space of the piston 12 in the pumping box 2, making the pumping efficiency higher and more The other end of each connecting rod 11 is jointly installed with a piston 12, and the piston 12 is slidably connected to the pumping box 2. A cavity is opened in the pumping box 2, and the cavity is square in shape. The screw sleeve 10 and each side of the piston 12 are slidably connected to the inner wall corresponding to the position of the cavity, thereby limiting the screw sleeve 10 so that it can only reciprocate linearly but not rotate. The rotation of the reciprocating screw 6 drives the screw sleeve 10 to reciprocate, and at the same time drives the piston 12 to extract external water and release it into the pressure cylinder 3 through the water outlet pipe 5;

[0025] A hollow rod 9 is slidably connected in the pressure cylinder 3, a nozzle 14 is provided at the top of the hollow rod 9, an arc plate 8 is installed on the hollow rod 9, a reset mechanism is provided in the hollow rod 9, and the reset mechanism includes a pressure plate 15, and the pressure plate 15 is slidably connected in the pressure cylinder 3, and an arc base 16 is fixedly installed at the bottom of the pressure cylinder 3. The height of the arc base 16 is greater than the connection height between the water outlet pipe 5 and the pressure cylinder 3. A spring 17 is installed between the bottom surface of the pressure plate 15 and the top of the arc base 16. A through groove is provided on the pressure plate 15, and the through groove is aligned with the hollow rod 9. The hollow rod 9 is connected and connected with the nozzle 14. When the subway passes, wind force is generated, and the curved plate 8 generates an upward lifting force through the Bernoulli theorem, and when the pressure plate 15 is quickly lifted, the flow rate in the water outlet pipe 5 can be further accelerated, and the water source is accelerated to enter the pressure cylinder 3. Then, the water source enters the hollow rod 9 through the groove opened on the pressure plate 15 and is sprayed out through the nozzle 14. After the subway passes, it is reset by the spring 17 to prevent it from always remaining in an upward state when the subway ventilation system works.

[0026] When the utility model is used, when the subway passes through the tunnel, a large amount of wind will be generated, which drives the impeller 7 to rotate, thereby driving the reciprocating screw 6 to rotate, and then the screw sleeve 10 connected to the reciprocating screw 6 through the threaded connection moves linearly back and forth, thereby driving the piston 12 to extract the external water source and extract it into the pressure cylinder 3 through the water outlet pipe 5;

[0027] At the same time, the wind drives the curved plate 8 to rise, further accelerating the flow rate of water in the water outlet pipe 5 so that the water source enters the pressure cylinder 3, and then sprays the water source through the nozzle 14 and atomizes it through the wind. After the subway passes, the spring 17 acts on the pressure plate 15 to squeeze the pressure plate 15 downward. At the same time, the diameter of the through groove in the pressure plate 15 is small. During the squeezing process, the water source only enters the nozzle 14 from the through groove, and then the nozzle 14 continues to spray until the spring 17 is fully restored. The tunnel can be sprayed, humidified, and dusted sustainably without consuming additional energy, which is green and environmentally friendly.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
