[0019] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can also be combined in other examples

[0020] Example: The invention provides a waste heat recovery type ground source heat pump air conditioning unit as shown in Figures 1 to 9 the figure, including: A heat exchanger 12 that circulates and heats the user's water based on the ground heat source. A rotating wheel 21 driven by flowing water is installed at the inlet 18 of the heat exchanger 12; A plurality of groups of heat exchange tubes 111 are provided inside the heat exchanger 12. A rotating cleaning member 25 is arranged inside the heat exchange tubes 111.

[0021] Working principle: Conversion of water flow self-driving force. The water flow at the inlet 18 impacts the rotating wheel 21, converts the fluid kinetic energy into mechanical energy, and drives the rotating cleaning member 25 to rotate. Dynamic cleaning coverage mechanism. The rotating cleaning member 25 synchronously performs rotation and axial movement inside the heat exchange tubes 111, covers the tube wall with a spiral trajectory, and removes tiny scale. Zero-interference heat exchange mode. The cleaning member can completely withdraw from the heat exchange tubes 111 to the cavities at both ends, eliminating the flow resistance of the traditional fixed cleaning structure

[0022] Energy recycling is adopted to prevent scale formation by driving with the incoming water flow, achieving cleaning with zero additional energy consumption, which is more energy-saving compared to pure electric drive cleaning. It has a dead-angle-free self-cleaning function, with a rotary plus reciprocating compound motion, reduced thermal resistance, and full tube wall coverage. The heat transfer efficiency is guaranteed without loss. The cleaning component is designed for storage, avoiding permanent flow resistance loss and maintaining the designed flow velocity and heat transfer coefficient, compared with the traditional cleaning structure that causes flow velocity attenuation. Through the hydraulic self-driving and retractable cleaning structure, while ensuring zero-scale operation, the negative impact of the cleaning component on the heat transfer efficiency is eliminated.

[0023] Specifically, as Figures 1 to 3 shown, the heat exchanger 12 and the water tank 13 are installed on the base 11. A return water pipe 17 is provided at the inlet of the water tank 13. The water tank 13 is connected to the water inlet 18 of the heat exchanger 12. The water outlet 19 of the heat exchanger 12 is connected to a water distribution pipe 15. A number of groups of water outlet pipes 16 are provided on the water distribution pipe 15. A supply pump 14 is provided at the connection position of the water distribution pipe 15 and the water outlet pipes 16. The water outlet pipes 16 are used to connect to the user side to supply heat energy to the user. The water body after supplying heat energy completes the circulation process through the return water pipe 17. Other related control contents are well-known to those skilled in the art and will not be elaborated.

[0024] A number of groups of passive rotating rods 210 are installed inside the heat exchanger 12 through the heat exchange tubes 111. The rotary cleaning part 25 rotates and reciprocates inside the heat exchange tubes 111 through the passive rotating rods 210.

[0025] The rotary wheel 21 simultaneously drives a number of groups of passive rotating rods 210 through a driving structure. The rotary cleaning part 25 rotates following the passive rotating rods 210, thereby realizing the rotation of the rotary cleaning part 25 inside the heat exchange tubes 111. The rotary cleaning part 25 is slidably installed on the passive rotating rods 210. Pulling ropes 211 are provided at both ends of the heat exchange tubes 111. The two groups of pulling ropes 211 are respectively connected to both ends of the rotary cleaning part 25. The two groups of pulling ropes 211 are used to pull the rotary cleaning part 25 to achieve reciprocating movement cleaning.

[0026] A number of groups of heat exchange tubes 111 inside the heat exchanger 12 are distributed in a circular array. The passive rotating rods 210 are located at the axial positions inside the heat exchange tubes 111. The passive rotating rods 210 of the number of groups of heat exchange tubes 111 are synchronously driven to rotate through the driving structure. The axis position of the rotary wheel 21 is connected to an active rotating rod 27. The active rotating rod 27 drives the number of groups of passive rotating rods 210 to rotate through this driving structure.

[0027] The driving structure includes a driving wheel 22 and a driven wheel 23. The driving wheel 22 is installed on the driving rotating rod 27, and the driven wheel 23 is installed on the driven rotating rod 210. Between multiple groups of driven wheels 23, synchronous driving transmission is carried out through a transmission belt 29. The driving wheel 22 drives the driven wheel 23 through the transmission belt 29 to simultaneously drive multiple groups of driven rotating rods 210 by the rotating wheel 21.

[0028] It further includes a driving wheel 22 installed on the driving rotating rod 27. At the other end of the driving rotating rod 27 where the driving wheel 22 is located, a driving motor is provided. The driving motor is used to drive the driving wheel 22 and the rotating wheel 21 to rotate, realizing the driving rotation of the driving wheel 22 for multiple groups of driven rotating rods 210, and at the same time realizing the driving rotation of the rotating wheel 21 to improve the water inlet effect of the water inlet 18.

[0029] As Figure 6 shown, driving clutches 215 are provided between the driving rotating rod 27 and the driving wheel 22, and between the driving motor and the driving wheel 22. Through the driving clutches 215, the selection and on / off of two driving modes of the driving rotating rod 27 and the driving motor can be realized.

[0030] Hoists 24 are installed at both external ends of the heat exchanger 12. The hoists 24 drive the reciprocating movement of the rotating cleaning member 25 through two groups of pulling ropes 211.

[0031] As Figure 4 shown, a bracket 110 is installed outside the heat exchanger 12. The bracket 110 is used for the installation of structures such as the driving wheel 22, the driven wheel 23, and the hoist 24. Furthermore, regarding the cleaning control method of this application, first, the ground source heat pump air conditioning unit of this solution has two states, a storage state and a cleaning state. In the storage state, the rotating cleaning member 25 is stored in the cavities at both ends of the heat exchanger 12. At this time, the rotating cleaning member 25 is not inside the heat exchange tube 111, so it will not affect the water flow velocity inside the heat exchange tube 111. In the cleaning state, the rotating cleaning member 25 rotates under the drive of the driven rotating rod 210, and at the same time, under the control of the pulling rope 211, the rotating cleaning member 25 reciprocates inside the heat exchange tube 111. Here, the way of rotating and reciprocating the rotating cleaning member 25 is used to completely clean the inside of the heat exchange tube 111. Here, the driving of the driven rotating rod 210 and the pulling rope 211 is essentially the control of the output mode of its driving source. This solution also includes a controller for controlling the driving source. The content of the controller here is common knowledge, so it will not be elaborated.

[0032] Both ends of the rotary cleaning member 25 are provided with rotating members 212. The rotating members 212 can rotate at both ends of the rotary cleaning member 25. Two groups of pull ropes 211 are connected to both ends of the rotary cleaning member 25 through the rotating members 212, that is, the pull ropes 211 are connected to the rotating members 212. The rotating members 212 are rotatably installed at one end of the rotary cleaning member 25, so that the pulling movement of the pull ropes 211 on the rotary cleaning member 25 does not interfere with the rotation of the rotary cleaning member 25.

[0033] The rotary cleaning member 25 is arranged in a spiral structure. A moving groove 213 is formed on the driven rotating rod 210. A sliding hole is formed at the axial position of the rotary cleaning member 25 and the rotary cleaning member 25 is slidably sleeved on the driven rotating rod 210 through the sliding hole. A positioning block 214 is connected inside the sliding hole of the rotary cleaning member 25. The positioning block 214 is slidably installed in the moving groove 213. This setting enables the driven rotating rod 210 to drive the rotary cleaning member 25 to rotate, and at the same time, the rotary cleaning member 25 can slide and move on the driven rotating rod 210.

[0034] A partition plate 112 is arranged inside the cavity at one end of the heat exchanger 12 close to the water inlet 18. The partition plate 112 divides the cavity into two chambers. The water inlet 18 is arranged on one of the chambers, and a water outlet 19 is arranged on the other chamber; On the chamber of the heat exchanger 12 for heat source circulation, a heat source inlet and a heat source outlet are provided. The flowing direction of the heat source inside the heat exchanger 12 is opposite to the flowing direction of the water. Under such a flowing direction setting, as Figure 4 shown, from the flowing direction of the user's water use, the temperature of the water gradually increases. From the flowing direction of the heat source, the heat source first contacts the water with a higher temperature, the temperature of the heat source decreases and then contacts the water with a lower temperature, so as to achieve a gradient increase in temperature and improve the heat utilization efficiency of the heat exchanger 12 for the heat source.

[0035] Optionally, as Figure 6 shown, support plates 26 and seals 216 are arranged at both ends inside the heat exchanger 12. The driven rotating rod 210 rotatably penetrates through the support plate 26, which can be used for positioning multiple groups of driven rotating rods 210. The driven rotating rod 210 penetrates through both ends of the heat exchanger 12, and the seal 216 is used for sealing the position where the driven rotating rod 210 penetrates; More specifically, a disassembly seat 28 is arranged inside the water inlet 18 of the heat exchanger 12, and the rotating wheel 21 is detachably installed inside the water inlet 18 through the disassembly seat 28.

[0036] The present invention also has the following comprehensive effects: Water flow self-driven cleaning system, with the rotating wheel 21 in linkage: The water flow at the water inlet 18 drives the rotating wheel 21 to rotate, synchronously drives all the passive rotating rods 210 to rotate through the main driving rod 27 and the transmission belt 29, and makes the rotating cleaning part 25 in the heat exchange tube 111 rotate self. Reciprocating cleaning mechanism: The winch 24 pulls the rotating cleaning part 25 to move axially along the passive rotating rod 210 through the two end ropes 211, realizing the combined movement of rotation and reciprocation. Dual-state intelligent switching, storage state: The rotating cleaning part 25 completely exits the heat exchange tube 111 to the two end cavities, with zero water flow resistance, ensuring the heat exchange efficiency. Cleaning state: The rotating cleaning part 25 performs spiral scraping in the heat exchange tube 111 to remove scale. Thermal efficiency optimized design, countercurrent heat exchange layout: The user's water flow and the ground heat source flow in opposite directions, with concentrated heat exchange in the high-temperature area and improved heat recovery rate. Annular array heat exchange tubes 111: The heat exchange surfaces are evenly distributed to avoid local overheating or overcooling.

[0037] Zero-energy consumption self-cleaning, the water flow drives the rotating wheel 21, and the basic cleaning is completed without an external power supply, reducing the operation and maintenance costs. The driving clutch 215 supports motor assistance to cope with low-flow conditions, such as at night. Lossless deep cleaning, spiral cleaning part + axial movement, covering the pipe wall, and the scale inhibition rate is reduced compared with the residue of the traditional fixed brush. The rotating part 212 decouples rotation or movement to avoid the winding and breakage of the rope 211. The heat exchange continues to be efficient, with the cleaning part storage design, the flow area of the heat exchange tube 111 is released, and the flow rate is increased. Countercurrent gradient heat exchange, the outlet water temperature is increased. The breakthrough in maintenance convenience, the detachable rotating wheel 21 design, the winch 24 is placed externally for quick replacement, and the rope 211 can be replaced without opening the tank. Technological generation advantages: Traditional heat pump: Shut down and disassemble the heat exchange tube 111, losing a large amount of working hours annually; This solution enables online self-cleaning and countercurrent efficiency improvement, enhancing the annual comprehensive energy efficiency.

The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present invention.
