[0027] like Figure 1-3 As shown, the cooling component includes an oil pipe 9 and a cooling pipe 10 which are arranged inside the cooling box 1 and have spiral cross-sections. The oil pipe 9 is sleeved on the outside of the cooling pipe 10, and the cooling pipe 10 is sleeved on the outside of the hollow column 2; the top and bottom ends of the oil pipe 9 are respectively fixedly connected with an oil inlet pipe 11 and an oil outlet pipe 12, the top of the oil inlet pipe 11 extends to the top of the cooling box 1, and the oil outlet pipe 12 extends to one side of the bottom end of the cooling box 1; the top and bottom ends of the cooling pipe 10 are respectively fixedly connected with a liquid inlet pipe 13 and a liquid outlet pipe 14, the top of the liquid inlet pipe 13 extends to the top of the cooling box 1, and the bottom of the oil outlet pipe 12 extends to the side of the bottom of the cooling box 1 away from the oil outlet pipe 12, the engine oil is transported to the inside of the oil pipe 9 through the oil inlet pipe 11, and then the coolant is transported to the inside of the cooling pipe 10 through the liquid inlet pipe 13, and then the engine oil is cooled by the cooperation of the oil pipe 9 and the cooling pipe 10.

[0028] like Figure 1-3 As shown, the bottom end of the cooling box 1 is fixedly connected to a material pipe 15, and a protective net 16 is installed inside the material pipe 15.
