Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Specific implementation method 1: Please refer to Figure 1-6 The present invention provides a technical solution: a low-temperature starting preheating device for modern mine trackless rubber-tyred vehicle transportation, comprising:

[0042] The engine housing 1 has an air guide pipe 31 and an exhaust pipe 17 connected to the front and rear sides of the engine housing 1, respectively, and a liquid inlet pipe 2 and a liquid discharge pipe 16 are plugged into the left and right sides of the engine housing 1, and a cooling chamber 13 and a combustion chamber 14 are formed inside the engine housing 1;

[0043] A liquid inlet pipe 2, the liquid inlet pipe 2 is connected to the cooling chamber 13, a first shaping layer 22 is attached to the inner wall of the liquid inlet pipe 2, and a cooling liquid flow channel 21 is formed inside the first shaping layer 22;

[0044] An air intake pipe 3, one end of which is connected to the air guide pipe 31, the air intake pipe 3 and the middle section of the liquid intake pipe 2 are connected side by side, and positioning columns 73 are welded on the outer surfaces of the air intake pipe 3 and the liquid intake pipe 2;

[0045] A top cover 4 is bonded to the top of the liquid inlet pipe 2 and the air inlet pipe 3, a third shaping layer 41 is bonded to the inner wall of the top cover 4, and a lamp holder 61 is fixed to the inner wall of the top cover 4;

[0046] A pressure rod 5, the pressure rod 5 is inserted into the top end of the telescopic rod 51, the bottom end of the telescopic rod 51 is inserted into the sleeve 52, and the sleeve 52 is located between the top cover 4 and the striker 15;

[0047] The irradiation lamp 6 is mounted on a lamp holder 61;

[0048] An expansion member 7, two ends of the expansion member 7 are symmetrically plugged with first light guides 71, an extended section of the first light guide 71 is connected with a second light guide 72, and the second light guide 72 is in contact with a magnetic sheet 74;

[0050] The light guide rod 9 penetrates the first shaping layer 22 and the second shaping layer 32 , and a focusing head 91 is fused to one end of the light guide rod 9 .

[0051] When using the modern low-temperature starting preheating device for mine trackless rubber-wheeled vehicle transportation, the irradiation lamp 6 is lit, and the light is irradiated on the second light pipe 72 and the focusing head 91. The light enters the coolant flow channel 21 and the clean air flow channel 33 along the second light pipe 72 and the light guide rod 9, and is reflected and converged by the shaping layer inside the liquid inlet pipe 2 and the air inlet pipe 3, and irradiates on the expansion member 7. The expansion member 7 quickly heats up and expands, so that the cavity inside it becomes larger, and the expansion member 7 pulls the second light pipe 72 to move inward. At this time, the water pump and air pump equipped on the engine are started, so that the coolant and air flow along the coolant flow channel 21 and the clean air flow channel 33. After passing through the cooling cavity 13 and the combustion chamber 14 in the engine housing 1, the fluid flows out from the drain pipe 16 and the exhaust pipe 17.
