Description

Technical Field

[0001] This utility model relates to the technical field of ground source heat pump equipment, and specifically to a ground source heat pump intelligent heating terminal equipment. Background Technology

[0002] Ground source heat pump engineering technology is an alternative to traditional coal-fired boilers in China, which not only have low energy efficiency but also cause serious air pollution. Therefore, coal-fired boilers are being phased out in some cities, while oil and gas boilers have high operating costs. Ground source heat pumps are a solution to heating and cooling problems with significant advantages in both technology and economy.

[0003] Chinese patent CN222747405U discloses a cooling and heating device for a composite energy underground structure, including a building body and an underground water tank. The building body has an underground heat exchange chamber at its bottom, and the underground water tank has a heat exchange mechanism inside. However, the device does not have a mechanism for cleaning the heat-conducting plates, requiring manual cleaning by staff at regular intervals. Scale easily clogs the through holes, reducing the contact area between the liquid and the heat-conducting plates and affecting the heat conduction efficiency of the device. Furthermore, there is no filter screen at the water outlet, making it impossible to filter out scale. Scale will enter the device with the liquid, potentially causing pipe blockage or equipment damage.

[0004] In the prior art, by setting a retractable conical block inside the heat-conducting plate, the through hole is unblocked, which helps to prevent the through hole from becoming blocked, thus reducing the contact area between the liquid and the heat-conducting plate and affecting the heat conduction efficiency. By setting a cleaning brush to clean the filter screen, it helps to prevent scale from entering the equipment and affecting the service life of the equipment. Utility Model Content

[0033] like Figures 1-4 The diagram illustrates a ground source heat pump intelligent heating terminal device according to an embodiment of the present invention, comprising: a building body 1, an underground heat exchange chamber 2 disposed below the building body 1, an underground water tank 3 disposed below the underground heat exchange chamber 2, a heating chamber 6 and a cooling chamber 7 fixedly connected to one end of the underground water tank 3, water pipes 9 fixedly connected to the heating chamber 6 and the cooling chamber 7 respectively, a water pump 13 fixedly connected to the other end of the water pipe 9 passing through the underground heat exchange chamber 2, and a heat exchange module 14 fixedly connected to the output end of the water pump 13 through the water pipe 9, the heat exchange module 14 being connected to the underground water tank 3 through the water pipe 9; the underground water tank 3 facilitates liquid storage, a heat-conducting plate 12 is disposed inside the underground water tank 3 for liquid heat exchange, and the water pump 13 transports the liquid inside the underground water tank 3 to the heat exchange module 14, and after heat exchange, the liquid is transported back to the underground water tank 3 through the water pipe 9;

[0034] The underground water tank 3 is equipped with two sets of heat-conducting plates 12. Each set of heat-conducting plates 12 is slidably connected to a sliding plate 16. The sliding plate 16 has several sets of evenly distributed mounting grooves 17 and through holes 18. The mounting grooves 17 and through holes 18 are arranged alternately. The through holes 18 are provided to increase the contact area between the liquid and the heat-conducting plates 12.

[0035] Two sets of mounting holes 19 are provided at one end of the underground water tank 3. A filter screen 20 is fixedly connected to each of the two sets of mounting holes 19. A cleaning brush 22 is provided below each set of mounting holes 19. The bottom end of the cleaning brush 22 is rotatably connected to the surface of the filter screen 20. By setting the filter screen 20 in the mounting holes 19, it is convenient to filter the liquid, which helps to prevent impurities such as mud, sand and dust in the water from entering the water pipe 9 and causing blockage of the water pipe, or entering the water pump 13 and causing damage to the water pump 13, thus affecting the service life of the water pump 13.

[0036] Two sets of heat-conducting columns 10 are fixedly connected to the bottom of the two sets of heat-conducting plates 12. Several sets of evenly distributed heat exchange plates 11 are fixedly connected to the outside of the heat-conducting columns 10. Heat dissipation holes are fixedly connected to the four corners of the surface of each set of heat exchange plates 11. By setting heat exchange plates 11 and heat dissipation holes on the heat exchange plates 11, the efficiency of liquid and soil temperature exchange is improved.

[0037] Both sets of heat-conducting plates 12 are fixedly connected with electric push rods 15. The output end of the electric push rods 15 is fixedly connected to the slide plate 16. Several sets of evenly distributed through holes 18 are opened on the heat-conducting plates 12. The through holes 18 are corresponding to the through holes 18 on the slide plate 16. The slide plate 16 is driven to slide along the heat-conducting plates 12 by driving the electric push rods 15.

[0038] Each set of mounting slots 17 is slidably connected to two sets of symmetrically arranged conical blocks 25. The mounting slots 17 are provided with guide grooves that are consistent with the guide of the conical blocks 25. The front ends of the two sets of conical blocks 25 are fixedly connected to two sets of telescopic rods 26, and the other ends of the two sets of telescopic rods 26 are fixedly connected to the slide plate 16. By setting the telescopic conical blocks 25, it is easy to unclog the through holes 18, which helps to prevent scale from clogging the through holes 18 and improves the heat conduction efficiency of the heat conduction plate 12.

[0039] Each telescopic rod 26 is fitted with a spring 27. One end of the spring 27 is fixedly connected to the conical stop block 25, and the other end of the spring 27 is fixedly connected to the slide plate 16. The diameter of the conical stop block 25 is the same as the diameter of the through hole 18. By setting the telescopic rod 26 and the spring 27, it is easy to drive the conical stop block 25 to slide along the mounting groove 17, so that the conical stop block 25 can be inserted into the through hole 18 to clear the through hole 18.

[0040] For example, such as Figure 4 As shown, the electric push rod 15 drives the slide plate 16 to slide along the heat-conducting plate 12, causing the through hole 18 to overlap with the mounting hole 19. The telescopic rod 26 and spring 27 facilitate the sliding of the conical block 25 along the mounting groove 17, allowing the conical block 25 to insert into the through hole 18 and clear the through hole 18. This helps prevent scale from clogging the through hole 18 and improves the heat conduction efficiency of the heat-conducting plate 12. The underground water tank 3 facilitates the storage of liquid. The heat-conducting plate 12 is installed inside the underground water tank 3 to exchange heat with the liquid. The water pump 13 is installed to transport the liquid inside the underground water tank 3 to the heat exchange module 14. After heat exchange, the liquid is transported back to the underground water tank 3 through the water pipe 9.

[0041] like Figures 2-6As shown, this invention illustrates a ground source heat pump intelligent heating terminal device according to one embodiment of the present invention. An electric motor 21 is fixedly connected below the two sets of mounting holes 19. A drive gear 23 is fixedly connected to the output end of the electric motor 21. The drive gear 23 meshes with a half-tooth gear 24. The half-tooth gear 24 is fixedly connected to a cleaning brush 22, which is rotatably connected to an underground water tank 3. Driving the electric motor 21 to rotate drives the drive gear 23 to rotate, which in turn drives the half-tooth gear 24 to rotate. A rotating shaft is fixedly connected inside the half-tooth gear 24 and rotatably connected to the underground water tank 3. The cleaning brush 22 is fixedly connected to the outside of the rotating shaft. Driving the rotating shaft to rotate the cleaning brush 22 cleans the filter screen 20, which helps prevent scale buildup and filter screen clogging.

[0042] The two sets of mounting holes 19 are respectively connected to the heating chamber 6 and the cooling chamber 7. The connection between the heating chamber 6 and the cooling chamber 7 and the water pipe 9 is fixedly connected with a water stop valve 8. By setting the water stop valve 8, it is easy to control the liquid entering the heating chamber 6 or the cooling chamber 7, so as to cool or heat the liquid.

[0043] An air conditioner 4 is fixedly connected to the building body 1. Two sets of transmission pipes 5 are fixedly connected to the bottom of the air conditioner 4. The other ends of the two sets of transmission pipes 5 are fixedly connected to the water pipes 9 at both ends of the heat exchange module 14. The air conditioner 4 is used to adjust the temperature inside the building body 1.

[0044] For example, such as Figure 6 As shown, the air conditioner 4 is set to adjust the temperature inside the building body 1. The water stop valve 8 is set to control the liquid entering the heating chamber 6 or the cooling chamber 7 to cool or heat the liquid. The electric motor 21 drives the drive gear 23 to rotate, and the drive gear 23 drives the half gear 24 to rotate. The half gear 24 has a rotating shaft fixedly connected inside. The rotating shaft is rotatably connected to the underground water tank 3. The cleaning brush 22 is fixedly connected to the outside of the rotating shaft. By driving the rotating shaft to rotate, the cleaning brush 22 rotates to clean the filter screen 20, which helps to prevent scale from clogging the filter screen.
