DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0029] In one embodiment of the present invention, see Figures 1 to 8A ground cooling system for a communication base station includes a rustproof metal tank body 1, a base station box 33, a heat absorption component 41, and a flow guide component 42; a mounting seat 34 is fixedly connected to the bottom of the base station box 33, the rustproof metal tank body 1 is buried under the stratum, an inner sleeve 2 is fixedly connected to the rustproof metal tank body 1, and multiple groups of equidistantly distributed heat insulation partitions 3 are fixedly connected between the inner sleeve 2 and the inner wall of the rustproof metal tank body 1, and a liquid storage bin 4 is arranged between two adjacent groups of heat insulation partitions 3, the outer wall of the inner sleeve 2, and the inner wall of the rustproof metal tank body 1, so that the heat in the liquid storage bin 4 is prevented from being transferred to the adjacent liquid storage bin 4 through the heat insulation partition 3. The temperature sensing control valve 20 is installed on the liquid inlet end of the liquid storage tank 4. When the temperature of the liquid in the liquid storage tank 4 is too high, the temperature sensing control valve 20 is closed. When the temperature of the liquid in the liquid storage tank 4 drops to a low temperature range, the temperature sensing control valve 20 is opened. The liquid inlet ends of the multiple groups of liquid storage tanks 4 are connected in parallel with injection pipes 19. The side wall of the rust-proof metal tank body 1 is fixedly connected with a heat conducting block 5. One end of the heat conducting block 5 is arranged in the liquid storage tank 4 to absorb the heat in the coolant in the liquid storage tank 4. The other end of the heat conducting block 5 is arranged outside the rust-proof metal tank body 1 to contact the soil outside the rust-proof metal tank body 1.

[0030] The bottom of the rust-proof metal tank body 1 is fixedly connected with a conical fixing block 6, and the bottom of the conical fixing block 6 is fixedly connected with a deep-inserted cone barrel 7. Compared with the rust-proof metal tank body 1, the deep-inserted cone barrel 7 is inserted into the stratum at the bottom of the rust-proof metal tank body 1. A guide pipe 8 is fixedly connected inside the deep-inserted cone barrel 7. One end of the guide pipe 8 is arranged at the bottom of the deep-inserted cone barrel 7. A guide groove 39 is arranged between the outer wall of the guide pipe 8 and the inner wall of the deep-inserted cone barrel 7. A plurality of groups of drainage grooves 9 are arranged in the conical fixing block 6, and each group of drainage grooves 9 connects the guide groove 39 with the liquid storage tank 4. The coolant enters the top of the guide groove 39 from the liquid storage tank 4 along the drainage groove 9, and then flows along the guide groove 39 to the bottom of the deep-inserted cone barrel 7, and finally flows into the guide pipe 8 from the bottom of the deep-inserted cone barrel 7;

[0031] A fixed seat 10 fixedly connected to the inner wall of the deep inserted cone barrel 7 is provided on the top of the drainage groove 9, and a rotating frame 11 is rotatably connected to the fixed seat 10 through a bearing, and a rotating cylinder 12 is fixedly connected to the rotating frame 11, and the rotating cylinder 12 is arranged between the outer wall of the guide tube 8 and the inner wall of the deep inserted cone barrel 7. The outer wall of the rotating cylinder 12 slides relative to the inner wall of the deep inserted cone barrel 7 to seal the connection between the drainage groove 9 and the guide groove 39, and a group of liquid inlet ports 15 are provided on one side of the rotating cylinder 12, and the liquid inlet ports 15 cooperate with multiple groups of drainage grooves 9. Multiple groups of tangential drive grooves 16 are provided on the outer wall of the rotating cylinder 12, and the tangential drive grooves 16 are tangentially arranged along the rotating cylinder 12. The multiple groups of tangential drive grooves 16 and the liquid inlet ports 15 are distributed circumferentially along the outer wall of the rotating cylinder 12. When the liquid inlet port 15 is connected to a group of drainage grooves 9, the multiple groups of tangential drive grooves 16 are connected to the remaining drainage grooves. 9 is connected, and the pressure difference on both sides of the rotating cylinder 12 is converted into the rotational driving force of the rotating cylinder 12 by setting the tangential driving groove 16. The bottom of the drainage groove 9 is provided with a rotating bracket 13 fixedly connected to the inner wall of the deep-inserted cone barrel 7. The bottom of the rotating cylinder 12 is fixedly connected with a rotating sealing groove 14. The rotating sealing groove 14 and the rotating bracket 13 are rotatably sealed with each other. A liquid guide gap 40 is provided between the rotating cylinder 12 and the inner wall of the guide tube 8. The liquid guide gap 40 connects the liquid inlet 15 and the 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 cooperates with the outer wall of the guide tube 8 to seal the rotating frame 11 and the guide tube 8; the heat absorption component 41 is installed in the base station box 33; the guide component 42 is installed between the heat absorption component 41 and the rust-proof metal tank body 1;

[0032] During the installation process of the present invention, the rust-proof metal tank body 1 is first buried under a shallow stratum, and during 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. Since the stratum below five meters is less affected by the environment, the construction difficulty of burying the rust-proof metal tank body 1 is reduced, and then the base station box 33 is installed and fixed by the mounting seat 34, and the heat absorption component 41 and the rust-proof metal tank body 1 are installed and connected by the guide component 42, and then the coolant is injected into the heat absorption component 41 and the rust-proof metal tank body 1 through the guide component 42, thereby completing the installation of the equipment;

[0033] After the installation is completed, the flow guide component 42 can be started, and the low-temperature coolant in the flow guide pipe 8 enters the heat absorption component 41 along the flow guide component 42, so that the heat in the base station box 33 is absorbed by the heat absorption component 41, and then the coolant that has absorbed the heat flows back to the return pipe 24 along the heat absorption component 41, and finally flows into a group of liquid storage tanks 4 along the injection pipe 19, thereby realizing the absorption and transfer of heat in the base station box 33, and then the heat in the coolant in the liquid storage tank 4 is absorbed by the heat conductive block 5, and the heat is exported to the soil layer outside the rust-proof metal tank body 1, and then, due to the poor thermal conductivity of the soil, as the heat is continuously exported, the soil layer outside the rust-proof metal tank body 1 gradually rises. At this time, due to the setting of multiple groups of liquid storage tanks 4, the heat will only be transferred along the fan-shaped surface direction of the liquid storage tank 4 where the coolant circulates, and the soil layer temperature in other directions will not change much;

[0034] During the flow of the coolant, the coolant first flows from the liquid storage bin 4 into the liquid drainage groove 9, and then flows over the liquid inlet 15 into the liquid guide gap 40. At this time, since only one group of liquid inlets 15 is provided in the rotating cylinder 12, only one group of liquid storage bins 4 has coolant flowing out. The coolant then flows into the guide groove 39 through the liquid guide gap 40, and finally flows into the guide pipe 8. In the process, the coolant flows along the deep cone barrel 7 to the deeper formation, so that the heat in the coolant in the deep cone barrel 7 is absorbed again by the deeper formation. In this way, the over-high temperature of the coolant caused by the change of the temperature of the surface soil layer is avoided, and the coolant with a lower temperature flows into the heat absorption component 41 under the pump suction of the guide component 42, and then the coolant that has absorbed the heat flows into the injection pipe 19 from the heat absorption component 41. At this time, since no coolant flows out of the remaining groups of liquid storage tanks 4, there is no hydraulic change in the remaining groups of liquid storage tanks 4, and the pressure in the liquid storage tank 4 connected to the liquid inlet 15 is reduced, so the coolant in the injection pipe 19 will only flow into the liquid storage tank 4 connected to the liquid inlet 15;

[0035] With the continuous transfer of heat in the base station box 33, the temperature of the soil layer increases, and the temperature of the coolant in the liquid storage tank 4 also increases. Then, when the temperature in the liquid storage tank 4 exceeds the safety value, the temperature sensing control valve 20 is closed. At this time, no coolant flows into the liquid storage tank 4 connected to the liquid inlet 15. Therefore, the coolant in the injection pipe 19 will evenly flow into the remaining liquid storage tanks 4 not connected to the liquid inlet 15. At this time, the hydraulic pressure in the remaining multiple groups of liquid storage tanks 4 gradually increases, and the coolant in the liquid guide gap 40 is pumped by the vacuum pump 22, and the hydraulic pressure gradually decreases. At this time, the pressure difference on both sides of the rotating cylinder 12 gradually increases, and the pressure generated by the hydraulic pressure difference acts on the rotating cylinder 12. At this time, the pressure difference on both sides of the rotating cylinder 12 is converted into the rotational driving force of the rotating cylinder 12 through the setting of the tangential drive groove 16, The rotating cylinder 12 is driven to rotate. At this time, when the liquid inlet 15 in the rotating cylinder 12 rotates from one group of drainage grooves 9 to the next group of drainage grooves 9, another group of liquid storage bins 4 is connected with the liquid inlet 15. At this time, the coolant in the other group of liquid storage bins 4 flows into the liquid guide gap 40 along the liquid inlet 15, so as to replenish the coolant in the guide groove 39 again, and the excess pressure in the other liquid storage bins 4 flows back to the liquid storage bins 4 connected with the liquid inlet 15 through the liquid injection pipe 19, and the rotating cylinder 12 no longer rotates under the limit of the high-speed flowing coolant, so as to realize the self-calibration of the drainage grooves 9 and the liquid inlet 15, and then when the coolant flow in the drainage grooves 9 connected with the liquid inlet 15 is low, the rotation limit of the rotating cylinder 12 disappears, and it rotates again under the action of the rotation driving force;

[0036] Then, the heat in the coolant in the liquid storage tank 4 with the temperature sensing control valve 20 closed will be transferred to the stratum around the rust-proof metal tank body 1 under the continuous transfer of the heat conducting block 5, and the heat will be slowly dissipated through the slow conduction of the stratum. When the coolant in the liquid storage tank 4 drops to a predetermined value, the temperature sensing control valve 20 will automatically open.

[0037] The equipment then repeats the above process, thereby achieving cyclic heat conduction of multiple groups of liquid storage tanks 4, and then achieving sequential heat dissipation of the rust-proof metal tank body 1 on different fan-shaped surfaces, thereby preventing the local stratum temperature around the rust-proof metal tank body 1 from being too high, affecting the heat dissipation effect of the ground cooling equipment.

[0038] In one case of this embodiment, see Figure 5 A spiral heat-conducting groove 18 is arranged in the side wall of the deep cone barrel 7, one end of the spiral heat-conducting groove 18 passes through the deep cone barrel 7 and is fixedly connected to the guide pipe 8, and the other end of the spiral heat-conducting groove 18 is arranged outside the deep cone barrel 7 and contacts with the external soil;

[0039] The present invention divides the guide groove 39 into spiral grooves through the spiral heat-conducting grooves 18. At this time, when the coolant flows in the guide grooves 39, the coolant flows along the spiral grooves under the guidance of the spiral heat-conducting grooves 18, and in this process, the contact area between the coolant and the spiral heat-conducting grooves 18 is increased. The heat in the coolant is absorbed by the spiral heat-conducting grooves 18 and transferred to the soil outside the deep-inserted cone barrel 7, so that the heat in the coolant is further absorbed by the soil outside the deep-inserted cone barrel 7, and the coolant that has absorbed the heat flows into the guide pipe 8 again.

[0040] In one case of this embodiment, see Figure 2 The heat absorption component 41 includes two groups of symmetrically arranged main pipes 35 fixedly connected in the base station box 33, and multiple groups of equidistantly distributed heat absorption tubes 38 are fixedly connected between the main pipes 35. A fourth connector 36 is installed on the liquid inlet end of one group of main pipes 35, and a fifth connector 37 is installed on the liquid outlet end of the other group of main pipes 35;

[0041] The heat absorption component 41 flows into a plurality of heat absorption tubes 38 through a group of main pipes 35, and then the cooling liquid that has absorbed the heat flows into another group of main 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 this embodiment, see Figure 3 and Figure 5 The flow guide assembly 42 includes a flow tube fixedly connected to the injection tube 19, a first connector 25 is installed on the liquid inlet end of the return tube 24, a mounting frame 21 is fixedly connected in the inner sleeve 2, a vacuum pump 22 is fixedly connected to the mounting frame 21, a suction tube 23 is fixedly connected to the liquid inlet end of the vacuum pump 22, the suction tube 23 is fixedly connected to the flow guide tube 8, the suction tube 23 is communicated with the flow guide tube 8, a liquid outlet pipe 26 is fixedly connected to the liquid outlet end of the vacuum pump 22, a connecting pipe 27 is fixedly connected to one side of the liquid outlet pipe 26, a second connector 29 is fixedly connected to the connecting pipe 27, the second connector 29 is connected to the fourth connector 36 by a set of heat-insulating hoses, and the first connector 25 is connected to the fifth connector 37 by another set of heat-insulating hoses;

[0043] The guide assembly 42 sucks the coolant in the guide pipe 8 through the vacuum pump 22 and the suction tube 23, and enters the liquid outlet pipe 26 along the vacuum pump 22, and then enters a group of main pipes 35 through the connecting pipe 27 and a group of insulated hoses, and flows into multiple groups of heat absorption pipes 38. The coolant that has absorbed the heat then flows back to the return pipe 24 along another group of main pipes 35 and another group of insulated hoses, and finally flows into the liquid storage tank 4 along the injection pipe 19.

[0044] In one case of this embodiment, see Figure 3The other side of the liquid outlet pipe 26 is fixedly connected to a drain pipe 30, and the drain pipe 30 is fixedly connected to a third connector 32. The connecting pipe 27 is provided with a first control valve 28, and the drain pipe 30 is provided with a second control valve 31;

[0045] When the device needs to inject coolant into the device, the first control valve 28 is opened and the second control valve 31 is closed. Then, the heat-insulating hose connected to the fifth connector 37 is unplugged and the heat-insulating hose is inserted into the barrel filled with coolant. 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 through the vacuum pump 22. At this time, vacuum negative pressure is generated in the rust-proof metal tank body 1. At this time, the coolant in the barrel enters the liquid storage tank 4 along the heat-insulating hose and the return pipe 24 under the pressure of the air pressure difference, thereby completing the injection of the coolant in the rust-proof metal tank body 1. After the injection is completed, the heat-insulating hose is inserted into the fifth connector 37. When the coolant in the rust-proof metal tank body 1 needs to be replaced later, it is only necessary to close the first control valve 28 and open the second control valve 31. At this time, the heat-insulating hose connected to the second connecting head 29 is unplugged, and the heat-insulating hose is inserted into the barrel filled with coolant. At this time, the vacuum pump 22 is started, and the vacuum pump 22 will make the coolant in the rust-proof metal tank body 1 flow along the liquid outlet pipe 26 and the drain pipe 30 to the third connecting head 32, and finally discharged. At the same time, a vacuum negative pressure is generated in the rust-proof metal tank body 1. At this time, the coolant in the barrel enters the liquid storage tank 4 along the heat-insulating hose and the reflux pipe 24 under the pressure of the air pressure difference, thereby replacing the coolant in the liquid storage tank 4.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
