[0028] The application further discloses an operation system of the ground source heat pump installation structure.

[0029] S1, the ground platform is fixed at a proper position through the ground nail, then the heat pump body is installed on the lifting platform, the servo motor drives the driving rod to rotate in the supporting sleeve, the driving rod drives the rotating column to rotate under the limiting of the two supporting tables, the rotating column drives the surface transmission gear to rotate synchronously, the lifting platform moves upwards of the groove under the limiting of the limiting rod, so that the overall height of the supporting table is increased under the cooperation of the lifting platform, thereby the height of the heat pump mechanism is adjusted, and the heat pump mechanism can adjust the pipe burying position according to the geographical environment;

[0030] S2, the rotating column drives the rotating disc to rotate synchronously, the movable rod drives the hinged seat to displace, the hinged seat drives the expansion rod to move to the two sides of the ground platform under the limiting of the sliding block in the sliding groove, the displacement of the expansion rod increases the contact area between the supporting mechanism and the ground platform, so that the stability of the supporting mechanism on the ground platform is improved, and the installation stability of the heat pump mechanism is improved by improving the stability of the supporting mechanism, the movable rod moves to the maximum position, and the lifting platform also rises to the highest position;

[0031] S3, after the heat pump body is installed, the spiral heat exchange pipe and the straight-flow heat exchange pipe in the heat pump mechanism are buried in the soil, the fixed anchor sleeve is equidistantly sleeved on the outer surface of the straight-flow heat exchange pipe through the buffer washer, and then the fixed anchor sleeve is fixed in the soil through the positioning anchor rod, in the heat exchange process, the heat pump body sends the fluid to the multi-channel flow divider through the conveying pipe, then the control valve of each joint in the multi-channel flow divider is controlled, so that the fluid enters the spiral heat exchange pipe through the liquid discharge pipe, the heat in the fluid is transmitted to the soil when the fluid flows in the spiral heat exchange pipe, the temperature of the soil is used to cool the fluid, the fluid is conveyed to the straight-flow heat exchange pipe through the pipeline after heat exchange in the spiral heat exchange pipe, and then the fluid is conveyed to the heat pump body from another joint of the multi-channel flow divider through the pipeline, after being heated by the heat pump body, the fluid is conveyed to the indoor equipment, after the heat pump body is used for a long time, the sealing cover is opened, then the cleaning liquid is injected into the heat pump mechanism through the descaling cleaning channel, so that the structure in the heat pump mechanism is descaled and cleaned.

[0032] S4. When the fluid is transported from the lower end to the upper end of the DC heat exchanger tube, the fluid will spiral upward under the guidance of the spiral guide vanes. At this time, turbulence will be generated in the DC heat exchanger tube, which will mix the fluid with the precipitate and reduce the flow resistance of the fluid in the DC heat exchanger tube. When the fluid flows, it will generate a certain impact force on the spiral guide vanes. Under the action of the support spring and the fixed plate, the spiral guide vanes will move up and down a short distance under the limit of the fixed ring. Since the edge of the spiral guide vane is in contact with the tube wall of the DC heat exchanger tube, the spiral guide vane will clean the inner wall of the DC heat exchanger tube and prevent the precipitate from adhering to the tube wall of the DC heat exchanger tube.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. In this invention, by setting a spiral heat exchange tube, compared with the traditional single straight tube or U-shaped tube, the spiral heat exchange tube effectively increases the heat exchange area of ​​the ground source heat pump, thereby improving the heat exchange efficiency of the ground source heat pump. At the same time, it ensures the stability of the heat exchange fluctuation of the ground source heat pump when facing complex geological conditions.

[0035] 2. In this invention, by setting up a support mechanism and an expansion mechanism, the rotation of the rotating column drives the transmission gear to rotate synchronously. Under the action of the fixed rack, the lifting platform moves upward to the support platform, thereby increasing the overall height of the support platform in cooperation with the support platform. This achieves the height adjustability of the ground source heat pump installation structure. During the height adjustment process, the rotating column also drives the rotating disk to rotate synchronously. With the cooperation of the movable rod and the hinge seat, the expansion rod is displaced under the limit of the slide groove and the slider. This allows the installation structure to increase the support area while adjusting the height, further ensuring the adjustability and stability of the installation structure. This makes the ground source heat pump installation structure applicable to different geological conditions, improving the versatility and reliability of the ground source heat pump installation structure.

[0036] 3. In this invention, by setting a fixed anchor sleeve, a buffer washer, and a positioning anchor rod, the buffer washer can absorb the impact force generated by soil settlement, effectively buffering the stress on the heat exchange tube, thereby avoiding the direct pressure of the fixed anchor sleeve causing damage to the heat exchange tube, improving the heat conduction effect of the heat exchange tube. At the same time, the fixed anchor sleeve can fix the overall structure of the heat exchange tube, preventing the heat exchange tube from shifting or deforming due to soil settlement and groundwater flow, further enhancing the stability of the installation structure, and making the installation structure applicable to areas with soft geological conditions, thus improving the applicability of the installation structure.

[0037] 4. In this invention, by setting up a descaling and cleaning channel, cleaning fluid is injected into the ground source heat pump system through the descaling and cleaning channel, thereby achieving descaling and cleaning of components such as multi-channel splitters, spiral heat exchange tubes and direct-flow heat exchange tubes. This effectively solves the problems of traditional structures being difficult to clean and the scale buildup on the inner wall of heat exchange tubes affecting heat exchange efficiency, reduces the cleaning difficulty of the ground source heat pump system, and ensures the heat exchange efficiency of the heat exchange tubes.

[0038] 5. In this invention, by setting a flow guiding mechanism, the inside of the heat exchange tube is made into a spiral channel by using spiral guide vanes. When the fluid flows in the spiral channel, turbulence is generated to enhance the mixing effect and mixing efficiency of the fluid, thereby effectively preventing the adhesion of precipitates in the heat exchange tube and avoiding the increase of fluid flow resistance due to precipitate adhesion. At the same time, the impact force of the fluid is used to move the spiral guide vanes, and the movement is used to clean some of the precipitates adhering to the inner wall of the heat exchange tube, thereby ensuring the fluid flow efficiency and heat exchange effect.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0050] In specific implementation, as shown in the drawings, Figures 1-8 The present application provides a technical solution: a ground source heat pump installation structure and a ground source heat pump system thereof, comprising a platform 1, the upper surface of the platform 1 is symmetrically distributed with a sliding groove 8, and the two side walls of the platform 1 are both fixedly installed with a fixed sleeve, and the inside of the fixed sleeve is penetrated by a ground nail;

[0051] A support mechanism 2 is arranged on the upper surface of the platform 1, and the support mechanism 2 comprises a support table 201, which is symmetrically and fixedly installed on the upper surface of the platform 1, and the upper surface of the support table 201 is provided with a groove 202, and the bottom inner wall of the groove 202 is fixedly installed with a limiting rod 2011, and the rotating column 207 is rotatably installed between the support tables 201, and the two ends of the rotating column 207 extend to the outside of the two sides of the support table 201, and the side wall of the support table 201 is provided with a stroke groove.

[0052] The outer surface of the rotating column 207 is symmetrically fixedly installed with a transmission gear 208, which is located outside the side wall of the support table 201. The inner wall of the groove 202 of the support table 201 is slidably installed with a lifting table 209. The lower surface of the lifting table 209 is provided with a limiting groove. The inner surface of the limiting groove is slidably connected with the outer surface of the limiting rod 2011. The upper surface of the ground table 1 is fixedly installed with a fixed table 203. The upper surface of the fixed table 203 is fixedly installed with a servo motor 204. The output end of the servo motor 204 is fixedly installed with a driving rod 205. One end of the driving rod 205 is fixedly connected with one end of the rotating column 207. The outer surface of the driving rod 205 is rotatably installed with a support sleeve 206. The lower surface of the support sleeve 206 is fixedly connected with the upper surface of the ground table 1.

[0053] A through groove is arranged on the side wall of the lifting table 209. The through groove is sleeved on the outside of the rotating column 207. The side wall of the lifting table 209 is fixedly installed with a fixed rack 2010. One end of the fixed rack 2010 extends to the outside of the side wall of the support table 201 through a stroke groove. The fixed rack 2010 is in meshing connection with the transmission gear 208. The lower surface of the heat pump body 301 is fixedly connected with the upper surface of the lifting table 209.

[0054] Specifically, by arranging the support mechanism 2, the servo motor 204 drives the driving rod 205 to rotate in the support sleeve 206. The driving rod 205 drives the rotating column 207 to rotate under the limitation of the two support tables 201 when rotating. The rotating column 207 drives the surface transmission gear 208 to synchronously rotate. Under the action of the fixed rack 2010, the lifting table 209 moves upwards of the groove 202 under the limitation of the limiting rod 2011. Thus, the overall height of the support table 201 is increased under the cooperation of the lifting table 209, so as to adjust the height of the heat pump mechanism 3, so that the heat pump mechanism 3 can adjust the pipe burying position according to the geographical environment.

[0055] The expansion mechanism 4 is arranged on the outer surface of the rotating column 207. The expansion mechanism 4 comprises rotating discs 403, which are equidistantly fixedly installed on the outer surface of the rotating column 207. The two side walls of the rotating disc 403 are rotatably installed with movable rods 404 through rotating shafts. One end of the movable rod 404 is rotatably installed with a hinged seat 405 through a rotating shaft.

[0056] The expansion mechanism 4 further comprises expansion rods 401, which are symmetrically distributed on the two sides of the rotating column 207. The upper surface of the expansion rod 401 is fixedly connected with the lower surface of the hinged seat 405. The lower surface of the expansion rod 401 is fixedly installed with sliding blocks 402. The outer surface of the sliding block 402 is slidably connected with the inner wall of the sliding groove 8.

[0057] Specifically, by setting the expansion mechanism 4, the rotating column 207 will drive the rotating disc 403 to rotate synchronously when rotating. With the rotation of the rotating disc 403, the movable rod 404 will drive the hinged seat 405 to displace. At this time, the hinged seat 405 will drive the expansion rod 401 to move to both sides of the platform 1 through the sliding block 402 under the limitation of the sliding groove 8. With the displacement of the expansion rod 401, the contact area between the supporting mechanism 2 and the platform 1 is increased, thereby improving the stability of the supporting mechanism 2 on the platform 1, and further improving the installation stability of the heat pump mechanism 3 by improving the stability of the supporting mechanism 2. When the movable rod 404 moves to the maximum position, the lifting platform 209 also rises to the highest position.

[0058] The heat pump mechanism 3 is provided with the upper surface of the supporting mechanism 2. The heat pump mechanism 3 comprises a heat pump body 301. The output end of the heat pump body 301 is fixedly installed with a conveying pipe 302. One end of the conveying pipe 302 is communicatedly installed with a multi-channel flow divider 303. The multi-channel flow divider 303 is connected by a pipeline.

[0059] One end of one of the joints of the multi-channel flow divider 303 is communicated by a pipeline with the heat pump body 301. The other end of one of the joints of the multi-channel flow divider 303 is communicatedly installed with a liquid discharge pipe 304. The liquid discharge pipe 304 is communicatedly installed with a control valve. The output end of the control valve is communicatedly installed with a spiral heat exchange pipe 305.

[0060] One end of the other joint of the multi-channel flow divider 303 is communicated by a pipeline with the heat pump body 301. The other end of the other joint of the multi-channel flow divider 303 is communicated by a pipeline with a control valve. The output end of the control valve is communicatedly installed with a straight-flow heat exchange pipe 306. The straight-flow heat exchange pipe 306 is communicated by a pipeline with the spiral heat exchange pipe 305.

[0061] The outer surface of the straight-flow heat exchange pipe 306 is sleeved with a fixed anchor sleeve 5. The inner surface of the fixed anchor sleeve 5 is fixedly installed with a buffer washer 6. The inner surface of the buffer washer 6 is fixedly connected with the outer surface of the straight-flow heat exchange pipe 306. The side wall of the fixed anchor sleeve 5 is fixedly installed with a positioning anchor rod 7. One end of the positioning anchor rod 7 is inserted into the soil.

[0062] The interface of the last joint of the multi-channel flow divider 303 is communicatedly installed with a descaling cleaning channel 307. One end of the descaling cleaning channel 307 is fixedly installed with a sealing sleeve. The upper surface of the heat pump body 301 is fixedly installed with a pressure and temperature double-monitoring sensor 308. The monitoring end of the pressure and temperature double-monitoring sensor 308 extends to the inside of the heat pump body 301.

[0063] Specifically, by setting the heat pump mechanism 3, the heat pump body 301 transports the fluid into the multi-channel distributor 303 through the conveying pipe 302, and then controls the control valve of each joint in the multi-channel distributor 303 to make the fluid enter the spiral heat exchange pipe 305 through the liquid discharge pipe 304. When the fluid flows in the spiral heat exchange pipe 305, the heat in the fluid is transmitted to the soil, and the temperature of the soil is used to cool the fluid. After the fluid is heat exchanged in the spiral heat exchange pipe 305, it is transported to the straight-flow heat exchange pipe 306 through the pipeline, and then transported to the heat pump body 301 from another joint of the multi-channel distributor 303. After being heated by the heat pump body 301, it is transported to the indoor equipment. With the long-time use of the heat pump body 301, the sealing cover is opened, and then the cleaning liquid is injected into the heat pump mechanism 3 through the descaling and cleaning channel 307, so as to descale and clean the structure in the heat pump mechanism 3.

[0064] The flow guide mechanism 9 is arranged in the heat pump mechanism 3, and the flow guide mechanism 9 comprises a fixed rod 901, and a spiral flow guide piece 902 is fixedly installed on the outer surface of the fixed rod 901.

[0065] The outer surface of the spiral flow guide piece 902 is attached to the inner wall of the straight-flow heat exchange pipe 306, the outer surface of the fixed rod 901 is slidably installed with a fixed ring 905, the outer surface of the fixed ring 905 is equidistantly fixedly installed with a support rod 906, one end of the support rod 906 is fixedly connected with the inner surface of the straight-flow heat exchange pipe 306, and the support spring 904 is fixedly installed between the fixed ring 905 and the fixed disc 903.

[0066] Specifically, when the fluid is transported from the lower end to the upper end of the straight-flow heat exchange pipe 306, the fluid will spiral upward under the guidance of the spiral flow guide piece 902. At this time, the fluid in the straight-flow heat exchange pipe 306 will produce turbulent flow, so as to mix the fluid and the precipitate, and also reduce the flow resistance of the fluid in the straight-flow heat exchange pipe 306. When the fluid flows, a certain impact force will be generated on the spiral flow guide piece 902, and the spiral flow guide piece 902 impacted at this time will move up and down by a short distance under the limiting of the fixed ring 905 under the action of the support spring 904 and the fixed disc 903. Since the edge of the spiral flow guide piece 902 is attached to the pipe wall of the straight-flow heat exchange pipe 306, the spiral flow guide piece 902 will clean the inner wall of the straight-flow heat exchange pipe 306, so as to avoid that the precipitate is attached to the pipe wall of the straight-flow heat exchange pipe 306.

[0067] The application also discloses an operation system of the ground source heat pump installation structure, which comprises the following steps:

[0068] S1, the ground platform 1 is fixed in place by the ground nail, and then the heat pump body 301 is installed on the lifting platform 209. The servo motor 204 drives the driving rod 205 to rotate in the support sleeve 206. When the driving rod 205 rotates, the rotating column 207 rotates under the limiting of the two support tables 201. With the rotation of the rotating column 207, the surface transmission gear 208 rotates synchronously. Under the action of the fixed rack 2010, the lifting platform 209 moves above the groove 202 under the limiting of the limiting rod 2011, thereby increasing the overall height of the support table 201 under the cooperation of the lifting platform 209, so as to adjust the height of the heat pump mechanism 3, so that the heat pump mechanism 3 can adjust the pipe laying position according to the geographical environment;

[0069] S2, the rotating column 207 rotates to drive the rotating disc 403 to rotate synchronously. With the rotation of the rotating disc 403, the movable rod 404 drives the hinged seat 405 to displace. At this time, the hinged seat 405 drives the expansion rod 401 to move to both sides of the ground platform 1 under the limiting of the sliding block 402 in the sliding groove 8. With the displacement of the expansion rod 401, the contact area between the support mechanism 2 and the ground platform 1 is increased, thereby improving the stability of the support mechanism 2 on the ground platform 1, and further improving the installation stability of the heat pump mechanism 3 by improving the stability of the support mechanism 2. When the movable rod 404 moves to the maximum position, the lifting platform 209 also rises to the highest position;

[0070] S3, after the installation of the heat pump body 301 is completed, the spiral heat exchange pipe 305 and the straight-through heat exchange pipe 306 in the heat pump mechanism 3 are buried in the soil. When the straight-through heat exchange pipe 306 is buried, a plurality of fixed anchor sleeves 5 are equidistantly sleeved on the outer surface of the straight-through heat exchange pipe 306 through the buffer washer 6, and then the fixed anchor sleeves 5 are fixed in the soil through the positioning anchor rod 7. In the process of heat exchange, the heat pump body 301 delivers the fluid to the multi-channel flow divider 303 through the conveying pipe 302, and then controls the control valve of each joint in the multi-channel flow divider 303 to make the fluid enter the spiral heat exchange pipe 305 through the liquid discharge pipe 304. When the fluid flows in the spiral heat exchange pipe 305, the heat in the fluid is transmitted to the soil, and the temperature of the soil is used to cool the fluid.
