[0002] A semiconductor thermoelectric power generation system is a power generation system based on the thermoelectric effect, directly converting thermal energy (temperature difference) into electrical energy. It boasts advantages such as simple structure, high reliability, noise-free operation, and maintenance-free operation, demonstrating broad application potential in numerous fields. However, due to structural limitations, existing semiconductor thermoelectric power generation systems present the following challenges when applied in polar environments: First, existing semiconductor thermoelectric power generation systems utilize cooling fans or circulating water pumps as a cooling source, resulting in poor cooling at the cold end and, consequently, low power generation efficiency. Second, existing semiconductor thermoelectric power generation systems utilize an active start-up mechanism, requiring an external power source to power the cooling source (cooling fan or circulating water pump) in order for the semiconductor thermoelectric generator to generate electricity and thus activate the system. Consequently, existing semiconductor thermoelectric power generation systems require an external power source, making them inconvenient and costly to use.

[0050] The thermoelectric power generation device includes a semiconductor thermoelectric power generation sheet 201; the hot end of the semiconductor thermoelectric power generation sheet 201 is attached to the upper surface of the heat sink 102;

[0051] The phase change heat dissipation device includes a working fluid box 301 and a support plate 302. The outer bottom surface of the working fluid box 301 is in contact with the cold end of the semiconductor thermoelectric generator 201 on one hand, and is fixed to the open edge of the top of the heating box 101 on the other hand. The support plate 302 is recessed downward to form a main heat dissipation groove 302a and an auxiliary heat dissipation groove 302b. A main heat dissipation pipe 303 is connected between the main heat dissipation groove 302a and the top wall of the working fluid box 301; an auxiliary heat dissipation pipe 304 is connected between the auxiliary heat dissipation groove 302b and the top wall of the working fluid box 301.

[0052] The cooling device includes a cooling box 401 and a water storage tank 402; the top of the cooling box 401 is provided with an opening; the outer bottom surface of the cooling box 401 is fixed to the upper surface of the support plate 302, and the right edge of the bottom wall of the cooling box 401 extends beyond the support plate 302; the bottom wall of the cooling box 401 is recessed upward to form a heat exchange chamber 401a, and the heat exchange chamber 401a is connected to both the main heat dissipation slot 302a and the auxiliary heat dissipation slot 302b; the water storage tank 402 is fixed to the right outer side surface of the working medium box 301, and a water collecting pipe 403 is connected between the top wall of the water storage tank 402 and the right edge of the bottom wall of the cooling box 401;

[0053] The ice crushing device includes an ice crushing refrigerator 501 and a controller 502; the top and bottom ends of the ice crushing refrigerator 501 are both provided with openings, and the bottom opening of the ice crushing refrigerator 501 is docked with the top opening of the cooling box 401; a telescopic peeling mechanism and a clamping mechanism are respectively installed on the ice crushing refrigerator 501; the controller 502 is fixed to the left outer side of the heating box 101; the output end of the controller 502 is electrically connected to the control end of the telescopic peeling mechanism and the control end of the clamping mechanism at the same time; the input end of the controller 502 is electrically connected to the output end of the telescopic peeling mechanism and the output end of the clamping mechanism at the same time; the power supply end of the controller 502, the power supply end of the telescopic peeling mechanism, and the power supply end of the clamping mechanism are all electrically connected to the output end of the semiconductor thermoelectric power generation chip 201.

[0054] During operation, liquid working medium is preset in the working medium box 301 , and the output end of the semiconductor thermoelectric generator 201 is electrically connected to an external load.

[0055] The specific working process is as follows:

[0056] First, open the valve plate 103 and place the heat source into the heating box 101 for combustion. During this process, external air enters the heating box 101 through the flue gas pipe 104 to ensure the continuity of combustion, and the smoke generated by the combustion is discharged outward through the flue gas pipe 104.

[0057] Then, put the large pieces of ice and snow into the crushing refrigerator 501, set the working mode of the telescopic peeling mechanism to manual mode, and the telescopic peeling mechanism will perform telescopic peeling on the large pieces of ice and snow in the crushing refrigerator 501, thereby chopping them into pieces. The chopped small pieces of ice and snow fall into the cooling box 401 and act as a cold source.

[0058] Under the combined action of the heat source and heat sink, the working fluid circulates within the phase-change heat sink, dissipating heat through phase change. The specific process is as follows: Heat generated by the heat source combustion is transferred sequentially through the vapor chamber 102, the hot end of the semiconductor thermoelectric generator 201, and the cold end of the semiconductor thermoelectric generator 201 to the working fluid tank 301, causing the liquid working fluid to evaporate and become a gaseous working fluid. The gaseous working fluid then ascends into the heat exchange chamber 401a via the main heat dissipation pipe 303 and the main heat dissipation slot 302a, and then ascends into the heat exchange chamber 401a via the auxiliary heat dissipation pipe 304 and the auxiliary heat dissipation slot 302b. The gaseous working fluid in the heat exchange chamber 401a exchanges heat with the heat sink and condenses into a liquid working fluid. The liquid working fluid then returns to the working fluid tank 301 via the main heat dissipation slot 302a and the main heat dissipation pipe 303, and then returns to the working fluid tank 301 via the auxiliary heat dissipation slot 302b and the auxiliary heat dissipation pipe 304. During this process, the cold source in the cooling box 401 undergoes heat exchange with the gaseous working medium and melts into water, which then flows into the water storage tank 402 through the water collecting pipe 403 .

[0059] Based on the cyclic phase change heat dissipation of the working fluid, a temperature difference is maintained between the hot end and the cold end of the semiconductor thermoelectric power generation piece 201, thereby causing the semiconductor thermoelectric power generation piece 201 to start generating electricity, thereby starting the system.

[0060] After the system is activated, the semiconductor thermoelectric generator 201 supplies power to the controller 502, the telescopic peeling mechanism, and the clamping mechanism, as well as to the external load. The telescopic peeling mechanism is then set to automatic mode. Under the control of the controller 502, the telescopic peeling mechanism continues to peel large chunks of ice and snow within the crushed ice box 501. Simultaneously, under the control of the controller 502, the clamping mechanism clamps and removes any accumulated ice and snow adhering to the inner side of the crushed ice box 501.

[0063] A front pin hole 509a and a rear pin hole 509b are provided on the rear of each main support rod 509; a pin shaft 514 is passed through the two rear pin holes 509b; two ear plates 515 are sleeved on the side of the pin shaft 514; a first seat plate 516 is fixed on the two ear plates 515 in an upright position; two auxiliary support rods 517 are vertically fixed between the outer end surface of the support cover 503 and the rear surface of the guide plate 510, and the two auxiliary support rods 517 both pass through the first seat plate 516; a first forward and reverse motor 518 is fixed on the front surface of the first seat plate 516, and the output shaft of the first forward and reverse motor 518 rotates and passes through the first seat plate 516; the control end of the first forward and reverse motor 518 serves as a telescopic peeling mechanism control end; the power supply end of the first forward and reverse motor 518 serves as the power supply end of the telescopic peeling mechanism; a first driving gear 519 is fixedly mounted on the output shaft of the first forward and reverse motor 518, and the first driving gear 519 is engaged with the transmission gear 508; three front positioning posts 520 are vertically fixed to the left part of the outer end surface of the support cover 503; an encoder 521 is commonly fixed to the front ends of the three front positioning posts 520, and the input shaft of the encoder 521 faces backward; the output end of the encoder 521 serves as the output end of the telescopic peeling mechanism; the power supply end of the encoder 521 also serves as the power supply end of the telescopic peeling mechanism; a measuring gear 522 is fixedly mounted on the input shaft of the encoder 521, and the measuring gear 522 is engaged with the transmission gear 508;

[0064] A cutter disc 523 is coaxially fixed to the rear end of the screw rod 505 ; cutters 524 are fixed to the front and rear ends of the cutter disc 523 .

[0065] The working modes of the telescopic peeling mechanism include:

[0066] 1. Manual Mode: Pull the pin 514 out of the two rear pin holes 509b and the two lugs 515. Move the first base plate 516, the two lugs 515, the first forward / reverse motor 518, and the first drive gear 519 forward along the two auxiliary support rods 517. Then, insert the pin 514 into the two front pin holes 509a and the two lugs 515, thereby separating the first drive gear 519 from the transmission gear 508. Then, manually rotate the handle 513 back and forth. Driven by the handle 513, the second rotary arm 512, the two guide rods 511, and the transmission gear 508 rotate back and forth. Driven by the two guide rods 511, the first rotary arm 506, the screw 505, the cutter disc 523, and the cutter 524 not only rotate back and forth together but also move back and forth longitudinally.

The first base plate 516, the two lugs 515, the first forward / reverse motor 518, and the first drive gear 519 are moved rearward along the two auxiliary support rods 517. The pin 514 is then inserted into the two rear pin holes 509b and the two lugs 515, thereby engaging the first drive gear 519 with the transmission gear 508. Under the control of the controller 502, the output shaft of the first forward / reverse motor 518 rotates back and forth. Driven by the output shaft of the first forward / reverse motor 518, the first drive gear 519, the transmission gear 508, the two guide rods 511, the second swing arm 512, the measuring gear 522, and the input shaft of the encoder 521 all rotate back and forth. Driven by the two guide rods 511, the first rotary arm 506, screw 505, cutter disc 523, and cutter 524 not only rotate back and forth together but also move back and forth longitudinally. This motion allows the cutter 524 to telescope and peel large chunks of ice and snow from the ice shredder 501. During this process, the encoder 521 monitors the number of revolutions of the measuring gear 522 in real time and transmits the results to the controller 502. Based on this monitoring, the controller 502 calculates the longitudinal travel of the cutter 524 in real time and controls it via the first forward and reverse motor 518, thereby preventing the cutter 524 from colliding with the ice shredder 501.

[0071] The clamping mechanism operates as follows: under the control of the controller 502, the output shaft of the second forward / reverse motor 528 rotates back and forth. Driven by the output shaft of the second forward / reverse motor 528, the second drive gear 529 rotates back and forth. Driven by the second drive gear 529, the two racks 531, the two connecting rods 530, the two clamping plates 526, and the two baffles 532 all move back and forth in opposite directions laterally, while the distance sensor 533 also moves back and forth laterally.
