[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described 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.

[0028] See Figure 1-6 As shown, the water source heat pump water intake station system includes a first water intake 10, a first buffer water tank 11, and a first water pump 12. The first water intake 10 and the bottom of the first buffer water tank 11 are connected by a first water intake pipe assembly 13. The first buffer water tank 11 is connected to a first drainage pipe 14, and the first water pump 12 is installed on the first drainage pipe 14. Water at the first water intake 10 can flow into the first buffer water tank 11 through the first water intake pipe assembly 13 by pumping, siphoning, or high-low flow. The water in the first buffer water tank 11 is then transported by the first water pump 12 and flows from the first drainage pipe 14 to the water source side of the heat pump unit for use by the water source heat pump. The first water intake 10 can be sourced from a river, groundwater, or other water source.

[0029] A first water diversion pipe group is provided in the first buffer water tank 11, and the first water diversion pipe group includes a water diversion pipe 15 and a water diversion hose 16. One end of the water diversion hose 16 is connected to the water diversion pipe 15, and the other end is connected to the first drainage pipe 14; that is, when the first water pump 12 is working, the water in the first buffer water tank 11 enters the first drainage pipe 14 through the water diversion pipe 15 and the water diversion hose 16.

[0030] A flip cover 17 is provided at the top center of the first buffer water tank 11. One side of the flip cover 17 is rotatably connected to the top outer side of the first buffer water tank 11 through a pin shaft. A handle 18 is fixedly provided above the other side of the flip cover 17 to facilitate the flipping of the flip cover 17. An automatic lifting mechanism is installed on the flip cover 17, which is connected to the water diversion pipe 15 to drive the water diversion pipe 15 to rise and fall in the first buffer water tank 11; a liquid level sensor 19 is installed in the first buffer water tank 11 to detect the water level in the first buffer water tank 11, and the liquid level sensor 19 forms a signal connection with the automatic lifting mechanism. That is, in order to avoid the water diversion pipe 15 being located too high in the first buffer water tank 11, affecting the water diversion flow, and being located at the bottom of the first buffer water tank 11, which will cause water containing more soil particles to enter the drainage pipe and affect the energy supply stability of the water source side of the water source heat pump, the inlet of the water diversion pipe 15 is constrained to the middle position below the water surface in the buffer water tank through the automatic lifting mechanism, so that the water diversion pipe 15 can divert water from the middle position of the water depth; the water level height is obtained in real time through the liquid level sensor 19 and fed back to the automatic lifting mechanism, and the automatic lifting mechanism automatically adjusts the lifting position of the water diversion pipe 15 according to the water level height.

[0031] In some implementations, the inlet of the water diversion pipe 15 is arranged toward the top of the first buffer water tank 11 to mainly divert water from the upper middle portion of the buffer water tank, thereby avoiding direct introduction of water from the bottom of the buffer water tank as much as possible.

[0032] In some implementations, the water diversion pipe 15 is a metal pipe with a certain weight to increase the stability of the water diversion pipe assembly in the buffer water tank.

[0033] In some embodiments, the automatic lifting mechanism includes a lifting motor 20, a reducer 21, a winding wheel 22, a lifting rope 23, and a connecting assembly 24. The lifting motor 20 is fixedly assembled on the outside of the flip cover 17 through the bottom mounting plate. The output end of the lifting motor 20 is transmission-connected to the input end of the reducer 21. The winding wheel 22 is assembled on the output end of the reducer 21. The upper end of the lifting rope 23 is wound around the outer periphery of the winding wheel 22. The connecting assembly 24 is connected between the water diversion pipe 15 and the lower end of the lifting rope 23. The lifting motor 20 provides power, and the reduction transmission of the reducer 21 can make the winding wheel 22 rotate, so that the lifting rope 23 can be retracted and released, thereby realizing the position change of the drainage pipe.

[0034] In some implementations, the flip cover 17 is provided with a clearance hole 25 for the lifting cord 23 to pass through. A guide sleeve is removably mounted in the clearance hole 25 to guide the retraction and extension of the lifting cord 23. Guide tubes 26 are threadedly connected to the top and bottom of the flip cover 17, respectively. The two guide tubes 26 are positioned in the clearance hole to form the guide sleeves. The outer ends of the guide sleeves are designed with a curved surface to reduce wear on the lifting cord 23.

[0035] In some embodiments, the connection assembly 24 includes a connecting frame 27 and a locking block 28. The connecting frame 27 is rectangular with an open bottom. The lower end of the connecting frame 27 is rotatably mounted on the outer wall of the water diversion pipe 15 via a connecting pin 29, which can be threaded onto the outer periphery of the water diversion pipe 15. A winding post 30 is fixedly disposed in the middle portion of the upper end of the connecting frame 27. Specifically, a pair of support blocks 31 are fixed to the middle portion of the upper end of the connecting frame 27. The ends of the winding post 30 are mounted on the pair of support blocks 31. The winding post 30 between the pair of support blocks 31 forms a portion for the lifting rope 23 to be wound around. The distance between the pair of support blocks 31 is slightly larger than the cross-sectional dimensions of the lifting rope 23 to provide a certain positional constraint on the lifting rope 23. Specifically, the lower end of the lifting rope 23 passes below the winding post 30 and engages with the lifting rope 23 above the winding post, where it is locked by the locking block. At least two sets of locking blocks are arranged in an upper and lower arrangement to enhance the locking force on the lower end of the lifting rope 23. A set of locking blocks includes two locking blocks, which are locked by a locking pin 32 .

[0036] In some implementations, the water intake station system also includes a second water intake 33, a second buffer water tank 34, and a second water pump 35. A second water intake pipe assembly 36 connects the second water intake 33 to the bottom of the second buffer water tank 34. A second drainage pipe 37 is connected to the second buffer water tank 34, and the second water pump 35 is mounted on the second drainage pipe 37. The second buffer water tank 34 operates in the same manner as the first buffer water tank 11 described above, and also includes a corresponding water supply pipe assembly and a corresponding lifting mechanism. The first drainage pipe 14 and the second drainage pipe 37 can independently or jointly supply water to the water source heat pump. The second buffer water tank 34 is primarily designed to improve the water source stability of the water source heat pump and can also be used to supply water when the first buffer water tank 11 undergoes maintenance, thus avoiding water outages in the water source heat pump due to buffer tank maintenance.

[0037] In some implementations, a first backflush pipe 38 is connected to the first drainage pipe 14, communicating with the bottom of the second buffer water tank 34. A second backflush pipe 39 is connected to the second drainage pipe 37, communicating with the bottom of the first buffer water tank 11. For example, when the first buffer water tank 11 is used to supply water to a water-source heat pump, water from the first buffer water tank 11 can be partially diverted to the bottom of the second buffer water tank 34 to clean the bottom of the second buffer water tank 34 and then discharged through the second water intake pipe assembly 36, thereby reducing the accumulation of soil particles at the bottom of the second buffer water tank 34. Similarly, when the second buffer water tank 34 is used to supply water to a water-source heat pump, the bottom of the first buffer water tank 11 can also be cleaned.

[0038] In some implementations, the first backflush line 38 includes a first backflush main pipe 40 and a first backflush control valve 41. A first backflush branch pipe 42 is connected to the first backflush main pipe 40. The first backflush branch pipe 42 is connected to the bottom of the second buffer water tank 34, facing the second water intake pipe assembly 36. The bottom wall of the second buffer water tank 34 is formed into a slope 43 that gradually decreases from the first backflush branch pipe 42 toward the second water intake pipe assembly 36. The second water intake pipe assembly 36 can include a corresponding number of water intake pipes to the first backflush branch pipes 42, each of which can be equipped with a control valve for control. For example, the figures of this application illustrate the use of two water intake pipes and two first backflush branches 42, with one water intake pipe corresponding to one backflush branch. Two corresponding slopes are also provided, which also increases backflush efficiency.

[0039] In some implementations, the second backflush pipeline 39 includes a second backflush main pipe 44 and a second backflush control valve 45. A second backflush branch pipe 46 is connected to the second backflush main pipe 44. The second backflush branch pipe 46 is connected to the bottom of the first buffer water tank 11, facing the first water intake pipe assembly 13. The bottom wall of the first buffer water tank 11 is a gradually decreasing slope from the second backflush branch pipe 46 toward the first water intake pipe assembly 13. The second backflush pipeline 39 can have the same structure, layout, and operation as the first backflush pipeline 38, and will not be further described here.

[0040] In some implementations, it should be noted that the water intake station system pipeline can adopt the pre-filtration currently used in the water intake pipeline, such as arranging a multi-stage filter screen 47 at the water intake to ensure the smooth flow of water in the entire pipeline.

[0041] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention and are intended to illustrate the technical solutions of the present invention, rather than to limit them, let alone the patent scope of the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they may still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
