[0030] Based on Example 1, both the microwave source 1 and the microwave radiation device assembly 14 are fixed on the support frame assembly 7. The microwave power amplifier 6 is fixed above the microwave source 1, and the straight waveguide 10 is fixed on the side of the microwave source 1.

[0031] Example 5

[0032] Based on Example 1, the microwave power amplifier 6 is composed of a microwave amplifier 12 and a microwave phase regulator 13. The microwave amplifier 12 adjusts the microwave power, and the microwave phase regulator 13 adjusts the focusing depth.

[0033] Example 6

[0034] Based on Example 1, an array horn antenna group 9 is installed at the bottom of the microwave radiation device assembly 14 facing downward. The array horn antenna group 9 is docked with the straight waveguide 10.

[0035] Example 7

[0036] Based on Example 6, a radiator up and down starting plate 11 is installed on the array horn antenna group 9. The radiator up and down starting plate 11 is driven by a pipeline connection of a hydraulic system 15.

[0037] Example 8

[0038] Based on Example 7, the hydraulic system 15 is installed on the support frame assembly 7.

[0039] Example 9

[0040] Based on Embodiment 2, a cooling system assembly 16 is also installed on the water load 3.

[0041] Embodiment 10

[0042] Based on Embodiment 1, as Figure 3 shown, the straight waveguides 10 are distributed in a 4×4 array.

[0043] Embodiment 11

[0044] Based on the above embodiments, it includes a microwave system support frame assembly 7, a support plate assembly 8, a cooling system assembly 16, a microwave radiation device assembly 14, and a radiator upper and lower activation plate 11. It is characterized in that: on the microwave system architecture assembly 7, the support plate assembly 8, the cooling system assembly 16, the microwave radiation device assembly 14, and the radiator upper and lower activation plate 11 are installed through the support frame. On the support plate assembly 8, a microwave source 1, a microwave power amplification assembly 6, a circulator 2, and a water load 3 are installed; the microwave power amplification assembly 6 is equipped with a microwave amplifier 12 and a microwave phase regulator 13; the cooling system assembly is installed with a circulator 2 and a water load 3; the microwave radiation device assembly 14 is installed with a high-power RF cable 5, a waveguide coaxial converter group 4, a straight waveguide group 10, and an array horn antenna group 9.

[0045] Thus, microwave fragmentation of high-hard frozen soil can be achieved.

[0046] The microwave power amplifier assembly 6 is equipped with a microwave amplifier 12 and a microwave phase regulator 13, and has the functions of adjustable focusing depth of microwaves inside the frozen soil and adjustable microwave power. Thus, while the microwave power is amplified, the adjustment of the microwave phase can be realized, and finally the heating depth and heating efficiency of the microwaves inside the frozen soil are improved, achieving adjustable and controllable depth and rate of microwave fragmentation of frozen soil, greatly meeting the requirements of high-hard frozen soil fragmentation construction.

[0047] The cooling system assembly 16 is installed with a circulator 2 and a water load 3. Thus, microwave reflection during microwave transmission can be avoided from damaging microwave devices, and the microwave power amplification system can be cooled and protected to prevent damage to microwave transmission devices due to too high microwave temperature, greatly improving the reliability of the microwave transmission system.

[0048] The hydraulic assembly 15 is driven by a hydraulic pipeline 17 to be connected, and the hydraulic system 15 is installed on the microwave system support frame assembly 7. Thus, the up and down adjustment of the array horn antenna group system can be realized, greatly improving the mobility of the microwave radiation front.

[0049] An array of horn antennas 9 is installed on the microwave radiation device assembly 14. The horn array antenna 9 has the functions of high-gain microwave radiation, high radiation efficiency, and good directivity, realizing the directional focusing of microwaves inside the frozen soil. Thus, the advantages of high gain and high radiation efficiency can be achieved for the internal focusing of microwaves in the frozen soil, meeting the heating requirements for the fragmentation of high-hard frozen soil structures and facilitating the efficient fragmentation of frozen soil.

[0050] Therefore, the present invention:

[0051] By analyzing the frozen soil components, calculating the applicable microwave wavelength for frozen soil fragmentation, and determining the position of focused microwaves (i.e., determining the depth and speed of frozen soil fragmentation), high-hard frozen soil is fragmented by the radiation of microwaves from the radiator (the process of the microwave system fragmenting frozen soil is as Figure 4 shown). Microwaves are mainly generated by the microwave seed source 1, enter the microwave power amplifier 6 through the cable for microwave amplification and microwave phase adjustment, and are input to the circulator 2 and the water load 3 (this link avoids the damage of microwave reflection to microwave devices and also cools the microwave power amplifier). Finally, microwave radiation is carried out through the array of horn antennas 9. Through the adjustment of the microwave amplifier 12 and the microwave phase regulator 13, the present invention enables the adjustable focusing depth and fragmentation efficiency of microwaves inside the frozen soil, thus achieving efficient fragmentation of frozen soil.
