[0034] And a drainage mechanism 9 is used to reduce residual water, and the drainage mechanism 9 is arranged in the automatic lifting mechanism 7.

[0035] The air inlet 5 is provided with a filter.

[0036] Specifically, the lifting block 71 will automatically move up to drain water according to the weight of the water-absorbing body 76, which is more convenient and energy-saving. When the lifting block 71 moves up, the water in the water-absorbing body 76 will be squeezed out and switched to the thin hose 92, so that more water can be discharged, reducing the residual amount of water in the device. When the lifting block 71 moves down, the lifting frame 73 can hit the bottom end of the drying pipe 1 to prevent crawlers from loosening the soil, and the setting of the non-Newtonian fluid can play a role of automatic identification through a simple structure, and when the lifting frame 73 is suddenly pulled upward by the spring 2 711, the gas can recoil the air inlet 5 to prevent the filter screen on the air inlet 5 from accumulating too much debris.

[0037] In another embodiment provided by the present invention, the automatic lifting mechanism 7 includes a lifting block 71 that slides up and down in the inner cavity of the drying tube 1, the bottom end of the lifting block 71 is fixedly connected to a connecting sleeve block 72, and a lifting frame 73 is provided in the connecting sleeve block 72 for sliding up and down. A vent 74 is provided at the upper end of the lifting block 71, and an air guide port 75 is provided on the outer wall of the connecting sleeve block 72, and the air guide port 75 connects the connecting sleeve block 72 and the inner cavity of the drying tube 1. A water absorbent body 76 is fixedly connected to the inner cavity of the connecting sleeve block 72 on the upper side of the air guide port 75, and an extrusion slider 77 is provided at the bottom end of the lifting block 71 for horizontal sliding. A spring 1 78 is fixed between the extrusion slider 77 and the lifting block 71, and a through hole 712 is provided on the extrusion slider 77. A friction ring 1 79 is fixedly connected to the outer wall of the upper end of the lifting frame 73, and a friction ring 2 710 is fixedly connected to the inner wall of the connecting sleeve block 72.

[0038] Two vents 74 and two extrusion sliders 77 are symmetrically arranged about the extension rod 81 , and a plurality of air guide ports 75 are arranged in a ring shape with equal intervals.

[0039] Specifically, when too much water is absorbed on the water-absorbing body 76, the entire connecting sleeve block 72 will become heavier, the lifting block 71 will move upward, and the extension rod 81 will be squeezed downward by the upper inner wall of the drying tube 1. The lifting block 71 will fall freely due to gravity and automatically move upward to drain water according to the weight of the water-absorbing body 76, which is more convenient and energy-saving.

[0040] In another embodiment provided by the present invention, the identification mechanism 8 includes an extension rod 81 that slides up and down in the lifting block 71, the top of the extension rod 81 extends to the upper side of the lifting block 71, the bottom end of the extension rod 81 is fixedly connected to the lifting frame 73, and a spring 2 711 is fixedly connected between the upper end of the lifting frame 73 and the lifting block 71. A sliding plate 83 is fixedly connected to the outer wall of the extension rod 81, and a liquid storage chamber 82 is opened in the lifting block 71. The sliding plate 83 is slidably arranged in the liquid storage chamber 82, and a non-Newtonian fluid is placed in the liquid storage chamber 82.

[0041] The diameter of the sliding plate 83 is smaller than the diameter of the liquid storage chamber 82 .

[0042] Specifically, when the lifting block 71 moves downward, the lifting frame 73 can impact the bottom end of the drying pipe 1 to prevent crawlers from loosening the soil. In addition, the setting of the non-Newtonian fluid can achieve automatic recognition through a simple structure.

[0043] In another embodiment provided by the present invention, the discharge mechanism 9 includes a connecting pipe 91 arranged between the lifting block 71 and the connecting sleeve block 72, the connecting pipe 91 connects the vent 74 and the inner cavity of the connecting sleeve block 72, a discharge pipe 95 is provided in the lifting block 71, and one end of the discharge pipe 95 is connected to the outside of the lifting block 71, and the other end of the discharge pipe 95 is connected to the vent 74, and the bottom end of the vent 74 is connected to the inner cavity of the connecting sleeve block 72 by a thin hose 92, and a blocking block 93 is provided at the bottom end of the extrusion slider 77 for sliding up and down, and a spring three 94 is fixed between the top of the blocking block 93 and the extrusion slider 77.

[0044] An end of the blocking block 93 close to the drain pipe 95 is provided with an inclined sliding surface.

[0045] Specifically, when the lifting block 71 moves upward, the water in the water-absorbing body 76 will be squeezed out and switched to the thin hose 92, so that more water can be discharged, reducing the amount of residual water in the device, and when the lifting frame 73 is suddenly pulled upward by the spring 2 711, the gas can backwash the air inlet 5 to prevent the filter screen on the air inlet 5 from accumulating too much debris.

[0046] Working principle: When using the device, bury the cabinet 2 and the drying pipe 1 in the soil, extend the upper end of the drying pipe 1 to the ground, and make the drainage slot 6 also located on the ground. Then, the gas in the cabinet 2 is extracted through the vacuum pump, and the gas in the drying pipe 1 also enters the cabinet 2 from the air inlet 5, the air guide port 75, the connecting pipe 91, the air vent 74 and the branch pipe 3. The gas will filter the moisture when passing through the water absorption body 76. When the moisture on the water absorption body 76 is too much, the entire connecting sleeve 72 will become heavier, so the bottom end of the lifting frame 73 will gradually conflict with the bottom end of the inner cavity of the drying pipe 1, so that the friction ring 1 79 and the friction ring 2 710 on the lifting frame 73 will be separated. At this time, the spring 2 711 is in a stretched state, so that the spring 2 711 can bounce the lifting frame 73 upward. When the lifting frame 73 moves upward, it will squeeze When the slider 77 is squeezed to both sides, the through hole 712 on the extrusion slider 77 will no longer overlap with the vent 74, so that the gas cannot pass through the lifting block 71, so that the lifting block 71 moves upward under the suction action of the air pump, and can automatically move the lifting block 71 to the upper side for drainage. When the lifting block 71 moves to the upper side, the extension rod 81 will be squeezed downward by the upper inner wall of the drying tube 1, and the lifting frame 73 will move downward accordingly. The friction ring 1 79 and the friction ring 2 710 are tightly attached, and the lifting frame 73 no longer moves. The extrusion slider 77 moves toward the center of the lifting block 71 under the action of the elastic force, so that the vent 74 can be ventilated again, the suction force on the lifting block 71 is reduced, and the lifting block 71 will fall freely due to gravity, and automatically move upward to drain water according to the weight of the water absorption body 76, which is more convenient and energy-saving.

[0047] When the lifting block 71 moves upward, the extrusion slider 77 moves in the direction away from the extension rod 81, and then the blocking block 93 is squeezed upward, and the thin hose 92 can be connected to the drainage pipe 95. When the lifting frame 73 moves upward, the water in the water absorption body 76 is squeezed out, but at this time, the end of the drainage pipe 95 away from the thin hose 92 is in a closed state. At this time, the water cannot be discharged. When the drainage pipe 95 coincides with the drainage notch 6, the lifting frame 73 will continue to move upward, and the water in the water absorption body 76 will be quickly discharged to the outside through the thin hose 92, the drainage pipe 95 and the drainage notch 6. When the lifting block 71 moves downward, the lifting baffle 4 will automatically fall to block the drainage notch 6. By providing the connecting pipe 91 and the thin hose 92, the gas can flow from the connecting pipe 91 when dissipating heat, which can reduce the suction force of the vacuum pump. When draining water, switch to the thin hose 92, so that more water can be discharged, reducing the residual amount of water in the device;

[0048] When the lifting block 71 moves downward, the lifting frame 73 can impact the bottom end of the drying pipe 1, so that crawlers around the device can be moved away, preventing the crawlers from crawling back and forth and loosening the surrounding soil, which would affect the use of the distribution cabinet. A non-Newtonian fluid is placed in the liquid storage chamber 82. When the lifting frame 73 hits, it can prevent the lifting frame 73 and the sliding plate 83 from moving upward, preventing drainage and causing the lifting block 71 to move upward after the impact. When the water in the water absorption body 76 increases, the lifting block 71 will slowly move downward, and the lifting frame 73 will be slowly pressed upward. At this time, the non-Newtonian fluid will not hinder the upward movement of the lifting frame 73. The simple structure plays an automatic recognition role.

[0049] And when the lifting frame 73 is suddenly pulled upward by the spring 2 711, the vent 74 is closed, and the bottom end of the lifting frame 73 will suddenly press the gas in the inner cavity of the connecting sleeve 72 out from the air guide port 75, so that the lifting block 71 moves forward, and the gas can recoil to the air inlet 5, preventing the filter screen on the air inlet 5 from accumulating too much debris and affecting the overall heat dissipation efficiency.
