[0029] In one case of the present embodiment, refer to Figures 1-8The utility model relates to a communication base station ground cooling heat dissipation system, including rustproof metal jar body 1, base station box 33, heat absorbing component 41, flow guide component 42, base station box 33 bottom fixedly connected with mounting seat 34, rustproof metal jar body 1 is buried under the stratum, rustproof metal jar body 1 is fixedly connected with inner sleeve 2 in, and a plurality of groups of equidistance distribution heat insulation baffle 3 are fixedly connected between inner sleeve 2 and rustproof metal jar body 1 inner wall, and adjacent two groups of heat insulation baffle 3, inner sleeve 2 outer wall and rustproof metal jar body 1 inner wall are provided with liquid storage bin 4 between, so as to prevent the heat in liquid storage bin 4 from transferring to adjacent liquid storage bin 4 through heat insulation baffle 3, temperature response control valve 20 is installed on the liquid inlet end of liquid storage bin 4, when the liquid temperature in liquid storage bin 4 is too high, temperature response control valve 20 closes, when the liquid temperature in liquid storage bin 4 reduces to low temperature range, temperature response control valve 20 opens, and the liquid inlet end of a plurality of groups of liquid storage bin 4 is connected with liquid injection pipe 19 in parallel, rustproof metal jar body 1 side wall is fixedly connected with heat conduction block 5, one end of heat conduction block 5 is arranged in liquid storage bin 4, and the heat in cooling liquid in liquid storage bin 4 is absorbed, and the other end of heat conduction block 5 is arranged outside rustproof metal jar body 1 and contacts the soil outside rustproof metal jar body 1;

[0030] The bottom of the rustproof metal jar body 1 is fixedly connected with a conical fixed block 6, and the bottom of the conical fixed block 6 is fixedly connected with a deep insertion cone barrel 7. Compared with the rustproof metal jar body 1, the deep insertion cone barrel 7 is inserted into the stratum at the bottom of the rustproof metal jar body 1. A flow guide pipe 8 is fixedly connected in the deep insertion cone barrel 7. One end of the flow guide pipe 8 is arranged at the bottom of the deep insertion cone barrel 7. A flow guide groove 39 is arranged between the outer wall of the flow guide pipe 8 and the inner wall of the deep insertion cone barrel 7. A plurality of groups of liquid discharge grooves 9 are arranged in the conical fixed block 6. Each group of liquid discharge grooves 9 communicates the flow guide groove 39 and the liquid storage bin 4. The cooling liquid flows into the top of the flow guide groove 39 from the liquid storage bin 4 along the liquid discharge grooves 9, and then flows to the bottom of the deep insertion cone barrel 7 along the flow guide groove 39. Finally, the cooling liquid flows into the flow guide pipe 8 from the bottom of the deep insertion cone barrel 7.

[0031] The top of the drainage groove 9 is provided with a fixed seat 10 fixedly connected to the inner wall of the deep insertion cone barrel 7, a rotating frame 11 is rotatably connected in the fixed seat 10 through a bearing, a rotating cylinder 12 is fixedly connected to the rotating frame 11, the rotating cylinder 12 is arranged between the outer wall of the flow guide pipe 8 and the inner wall of the deep insertion cone barrel 7, the outer wall of the rotating cylinder 12 slides against the inner wall of the deep insertion cone barrel 7 to seal the connection between the drainage groove 9 and the flow guide groove 39, one side of the rotating cylinder 12 is provided with a group of liquid inlet openings 15, the liquid inlet openings 15 are matched with a plurality of drainage grooves 9, a plurality of tangential drive grooves 16 are arranged on the outer wall of the rotating cylinder 12, the tangential drive grooves 16 are arranged along the tangential direction of the rotating cylinder 12, the plurality of tangential drive grooves 16 are distributed in a circle along the outer wall of the rotating cylinder 12, when the liquid inlet openings 15 are connected with one group of drainage grooves 9, the plurality of tangential drive grooves 16 are connected with the remaining drainage grooves 9, and the pressure difference between the two sides of the rotating cylinder 12 is converted into a rotating driving force of the rotating cylinder 12 through the arrangement of the tangential drive grooves 16, the bottom of the drainage groove 9 is provided with a rotating bracket 13 fixedly connected to the inner wall of the deep insertion cone barrel 7, the bottom of the rotating cylinder 12 is fixedly connected with a rotating sealing groove 14, the rotating sealing groove 14 is rotatably sealed with the rotating bracket 13, a liquid guiding gap 40 is arranged between the rotating cylinder 12 and the inner wall of the flow guide pipe 8, the liquid guiding gap 40 connects the liquid inlet openings 15 and the flow guide groove 39, a rubber sealing ring 17 is fixedly connected to the inner wall of the rotating frame 11, the rubber sealing ring 17 is matched with the outer wall of the flow guide pipe 8 to seal the space between the rotating frame 11 and the flow guide pipe 8; the heat absorbing assembly 41 is installed in the base station box 33; the flow guide assembly 42 is installed between the heat absorbing assembly 41 and the rust-proof metal tank body 1.

[0032] In the installation process, first, the rust-proof metal tank body 1 is buried in a shallow stratum, and in the burying process, the deep insertion cone barrel 7 is inserted into a deeper stratum under the action of gravity, and penetrates into the stratum below five meters, because the stratum below five meters is less affected by the environment, thereby reducing the construction difficulty of burying the rust-proof metal tank body 1, then the base station box 33 is installed and fixed through the mounting seat 34, and the heat absorbing assembly 41 and the rust-proof metal tank body 1 are installed and connected through the flow guide assembly 42, then cooling liquid is injected into the heat absorbing assembly 41 and the rust-proof metal tank body 1 through the flow guide assembly 42, so as to complete the installation of the equipment.

[0033] After installation, the flow guide assembly 42 is started, and the low-temperature cooling liquid in the flow guide pipe 8 flows into the heat absorption assembly 41 along the flow guide assembly 42, thereby absorbing the heat in the base station box 33 through the heat absorption assembly 41, and then the cooling liquid that has absorbed the heat flows back into the return flow pipe 24 along the heat absorption assembly 41, and finally flows into a group of liquid storage bins 4 along the liquid injection pipe 19, thereby realizing the absorption and transfer of heat in the base station box 33. Then, the heat in the cooling liquid in the liquid storage bin 4 is absorbed by the heat conduction block 5 and is conducted out to the soil layer outside the rust-proof metal tank body 1. Then, due to the poor heat conduction performance of the soil, the soil layer outside the rust-proof metal tank body 1 gradually rises as the heat is continuously conducted out. At this time, due to the arrangement of multiple groups of liquid storage bins 4, heat will only be transferred in the direction of the fan-shaped surface of the liquid storage bin 4 along which the cooling liquid circulates, and the temperature of the soil layer in the remaining directions will not change much.

[0034] During the flow of the cooling liquid, the cooling liquid flows from the liquid storage bin 4 into the liquid discharge groove 9, and then flows into the liquid guide gap 40 through the liquid inlet 15. At this time, since only one group of liquid inlets 15 is arranged in the rotating cylinder 12, only one group of liquid storage bins 4 has cooling liquid flowing out. The cooling liquid then flows into the liquid guide groove 39 through the liquid guide gap 40, and finally flows into the flow guide pipe 8. During the process, the cooling liquid flows along the deep insertion cone barrel 7 to a deeper stratum, thereby absorbing the heat in the cooling liquid in the deep insertion cone barrel 7 through the deeper stratum, thereby avoiding the over-high temperature of the cooling liquid caused by the change of the temperature of the surface soil layer. The cooling liquid with lower temperature flows into the heat absorption assembly 41 under the pumping of the flow guide assembly 42, and then the cooling liquid that has absorbed the heat flows into the liquid injection pipe 19 from the heat absorption assembly 41. At this time, since there is no cooling liquid flowing out of the remaining groups of liquid storage bins 4, there is no change in hydraulic pressure in the remaining groups of liquid storage bins 4. Therefore, the pressure in the liquid storage bin 4 connected to the liquid inlet 15 decreases, and thus the cooling liquid in the liquid injection pipe 19 only flows into the liquid storage bin 4 connected to the liquid inlet 15.

[0035] With the continuous transfer of heat in the base station box 33, the soil temperature rises, the temperature of the coolant in the storage tank 4 also rises, and then when the temperature in the storage tank 4 exceeds the safety value, the temperature sensing control valve 20 is closed, at this time the storage tank 4 connected with the inlet 15 is not in the flow of coolant, so the coolant in the liquid injection pipe 19 will uniformly flow into the remaining storage tank 4 not connected with the inlet 15, at this time the hydraulic pressure in the remaining groups of storage tank 4 gradually rises, and the coolant in the guide gap 40 gradually decreases under the pumping of the vacuum pump 22, at this time the pressure difference on both sides of the rotating cylinder 12 gradually increases, and the pressure difference generated by the hydraulic pressure acts on the rotating cylinder 12, at this time the pressure difference on both sides of the rotating cylinder 12 is converted into the rotary driving force of the rotating cylinder 12 through the tangential driving groove 16, thereby driving the rotating cylinder 12 to rotate, at this time when the inlet 15 in the rotating cylinder 12 is rotated from one group of liquid discharge grooves 9 to the next group of liquid discharge grooves 9, another group of storage tanks 4 is connected with the inlet 15, at this time the coolant in another group of storage tanks 4 flows into the guide gap 40 along the inlet 15, thereby replenishing the coolant in the guide groove 39, and the excess pressure in the other storage tanks 4 is returned to the storage tank 4 connected with the inlet 15 through the liquid injection pipe 19, and the rotating cylinder 12 is no longer rotated under the limitation of the high-speed flowing coolant, thereby realizing the self-calibration of the liquid discharge groove 9 and the inlet 15, and then when the flow of coolant in the liquid discharge groove 9 connected with the inlet 15 is low, the rotation limit of the rotating cylinder 12 disappears, and the rotating cylinder 12 is again rotated under the action of the rotary driving force;

[0036] Then the heat in the coolant in the storage tank 4 closed by the temperature sensing control valve 20 is transferred to the surrounding soil layer of the rust-proof metal tank body 1 through the continuous transfer of the heat conducting block 5, and the heat is slowly dissipated through the slow conduction of the soil layer, when the coolant in the storage tank 4 is reduced to the predetermined value, the temperature sensing control valve 20 is automatically opened;

[0037] Then the equipment repeats the above process, thereby realizing the cyclic heat conduction of the multiple groups of storage tanks 4, and further realizing the sequential heat dissipation of the rust-proof metal tank body 1 on different fan surfaces, thereby preventing the local over-high temperature of the soil layer around the rust-proof metal tank body 1, and affecting the heat dissipation effect of the ground cooling of the equipment.

[0038] In one case of the present embodiment, please refer to Figure 5 , the spiral heat conduction groove 18 is arranged in the sidewall of the deep insertion cone barrel 7, one end of the spiral heat conduction groove 18 penetrates through the deep insertion cone barrel 7 and is fixedly connected to the guide pipe 8, and the other end of the spiral heat conduction groove 18 is arranged outside the deep insertion cone barrel 7 and contacts with the external soil;

[0039] The present application divides the flow guide groove 39 into spiral grooves by the spiral heat conduction groove 18, when the cooling liquid flows in the flow guide groove 39, the cooling liquid flows along the spiral grooves under the guidance of the spiral heat conduction groove 18, and in this process, the contact area of the cooling liquid with the spiral heat conduction groove 18 is increased, the heat in the cooling liquid is absorbed and transferred to the soil outside the deep insertion cone barrel 7 under the action of the spiral heat conduction groove 18, so that the heat in the cooling liquid is further absorbed by the soil outside the deep insertion cone barrel 7, and the cooling liquid that has absorbed the heat flows into the flow guide pipe 8 again.

[0040] In one case of the present embodiment, please refer to Figure 2 , the heat absorption assembly 41 comprises two groups of symmetrically arranged total connecting pipes 35 fixedly connected in the base station box 33, a plurality of groups of heat absorption pipes 38 equidistantly distributed and fixedly connected between the total connecting pipes 35, a fourth connecting head 36 installed on the liquid inlet end of one group of total connecting pipes 35, and a fifth connecting head 37 installed on the liquid outlet end of the other group of total connecting pipes 35;

[0041] The heat absorption assembly 41 flows into a plurality of groups of heat absorption pipes 38 through a group of total connecting pipes 35, and then the cooling liquid that has absorbed heat flows into another group of total connecting pipes 35, in this process, the heat in the base station box 33 is absorbed by the low-temperature cooling liquid.

[0042] In one case of the present embodiment, please refer to Figure 3 and Figure 5 , the flow guide assembly 42 comprises a flow pipe fixedly connected to the liquid injection pipe 19, a first connecting head 25 installed on the liquid inlet end of the backflow pipe 24, a mounting bracket 21 fixedly connected in the inner sleeve 2, a vacuum pump 22 fixedly connected to the mounting bracket 21, a suction pipe 23 fixedly connected to the liquid inlet end of the vacuum pump 22, the suction pipe 23 being fixedly connected to and communicating with the flow guide pipe 8, a liquid outlet pipe 26 fixedly connected to the liquid outlet end of the vacuum pump 22, a connecting pipe 27 fixedly connected to one side of the liquid outlet pipe 26, a second connecting head 29 fixedly connected to the connecting pipe 27, the second connecting head 29 being connected to the fourth connecting head 36 through a group of heat insulation hoses, and the first connecting head 25 being connected to the fifth connecting head 37 through another group of heat insulation hoses;

[0043] The flow guide assembly 42 sucks the cooling liquid in the flow guide pipe 8 through the vacuum pump 22 and the suction pipe 23, and then the cooling liquid flows into the liquid outlet pipe 26 along the vacuum pump 22, and then flows into a group of total connecting pipes 35 through the connecting pipe 27 and a group of heat insulation hoses, and then flows into a plurality of groups of heat absorption pipes 38, and then the cooling liquid that has absorbed heat flows back into the backflow pipe 24 along another group of total connecting pipes 35 and another group of heat insulation hoses, and finally flows into the liquid storage bin 4 along the liquid injection pipe 19.

[0045] When the device needs to inject cooling liquid into the device, the first control valve 28 is opened, the second control valve 31 is closed, then the heat insulation hose connected with the fifth connecting head 37 is pulled off, the heat insulation hose is inserted into the barrel containing cooling liquid, and then the vacuum pump 22 is started, so that the air in the rust-proof metal tank body 1 is discharged along the liquid outlet pipe 26 by the vacuum pump 22, at this time, the vacuum negative pressure is generated in the rust-proof metal tank body 1, at this time, the cooling liquid in the barrel is sent into the liquid storage bin 4 along the heat insulation hose and the return pipe 24 under the pressure difference of air pressure, so that the injection of the cooling liquid into the rust-proof metal tank body 1 is completed, after the injection is completed, the heat insulation hose is inserted into the fifth connecting head 37, then when the cooling liquid in the rust-proof metal tank body 1 needs to be replaced, the first control valve 28 is closed, the second control valve 31 is opened, at this time, the heat insulation hose connected with the second connecting head 29 is pulled off, and the heat insulation hose is inserted into the barrel containing cooling liquid, at this time, the vacuum pump 22 is started, the cooling liquid in the rust-proof metal tank body 1 flows into the third connecting head 32 along the liquid outlet pipe 26 and the liquid discharge pipe 30, and is finally discharged, at the same time, the vacuum negative pressure is generated in the rust-proof metal tank body 1, at this time, the cooling liquid in the barrel is sent into the liquid storage bin 4 along the heat insulation hose and the return pipe 24 under the pressure difference of air pressure, so that the cooling liquid in the liquid storage bin 4 is replaced.
