All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The following will describe in detail the specific implementation of the present invention with reference to specific embodiments.

[0023] Embodiment 1:

[0024] Please refer to Figure 1 , a kind of air source heat pump anti-freezing drainage structure is provided, which includes a water delivery pipeline 12, a heat pump pump body 13 is arranged on the water delivery pipeline 12, and an output pipeline 14 is externally connected to the heat pump pump body 13; an anti-freezing bracket 11 is arranged on the periphery of the water delivery pipeline 12, and the water delivery pipeline 12 and the output pipeline 14 are positioned within the frame of the anti-freezing bracket 11; the heat pump pump body 13 is also externally connected to a heat conduction pipeline 15, an inner pipe conductor 16 is arranged in the heat conduction pipeline 15, the inner pipe conductor 16 is externally connected to a heat supply pipeline 17, and the heat supply pipeline 17 is externally connected to a heat supply source 18.

[0025] By arranging the anti-freezing bracket 11, the water delivery pipeline 12 and the output pipeline 14 can be effectively protected from the influence of the low-temperature environment, and the pipelines can be prevented from freezing and bursting. The heat pump pump body 13 is externally connected to a heat conduction pipeline 15, an inner pipe conductor 16 is arranged in the heat conduction pipeline 15, the inner pipe conductor 16 is externally connected to a heat supply pipeline 17, and the heat supply pipeline 17 is externally connected to a heat supply source 18. This design can effectively transfer the heat of the heat supply source 18 into the water delivery pipeline 12 and the output pipeline 14, further improving the anti-freezing effect. The structure is simple in design, easy to install and maintain, and has a low cost, with high practicability and economy.

[0026] Embodiment 2:

[0027] The anti-freezing bracket 11 includes a frame 31, a positioning bolt 32 disposed on the frame 31, and a locking bolt 33 mounted on the positioning bolt 32. A pipe sleeve 34 is provided on the locking bolt 33; the pipe bodies of the water supply pipe 12 and the output pipe 14 are both inserted and positioned in the pipe sleeve 34.

[0028] When the water supply pipe 12 and the output pipe 14 are subjected to external impacts, due to the firm structural design of the frame 31, a stable support foundation can be provided. The positioning bolt 32 is deeply embedded in the frame 31 to ensure that when the pipe is subjected to longitudinal tensile force, such as the impact caused by the sudden acceleration or stop of the water flow inside the pipe, the positioning bolt 32 will not easily loosen or come out. The locking bolt 33 mounted on the positioning bolt 32 can tightly fix the pipe sleeve 34 through precise thread fit. Even when the pipe undergoes slight thermal expansion and contraction, the locking bolt 33 can adjust in time and always maintain a firm grip on the pipe.

[0029] Embodiment Three:

[0030] The heat pump pump body 13 includes a delivery pump body 22 and a heating pump body 21 disposed at the bottom of the delivery pump body 22. The delivery pump body 22 and the heating pump body 21 are of an integrated structure that is interconnected; water inlet sleeves 23 and output sleeves 24 are respectively provided at both ends of the delivery pump body 22.

The heat conduction pipe 15 is connected to the heat conduction pipe sleeve 26.

[0031] Connect the water inlet sleeve 23 of the delivery pump body 22 to the water supply pipe 12. During the connection process, use a sealing rubber ring to ensure the sealing performance of the connection and prevent water leakage. Similarly, tightly connect the output sleeve 24 to the output pipe 14 to ensure that the water flow after being treated by the heat pump can be smoothly delivered to each heating area.

[0032] Then, connect the heat conduction pipe 15 to the heat conduction pipe sleeve 26 at the heat flow inlet head 25 on the heating pump body 21 to ensure that heat can be stably introduced from an external heat source into the heating pump body 21. When connecting the heat conduction pipe 15, pay attention to checking the heat insulation performance of the pipe to reduce heat loss.

[0033] When the system operates, the delivery pump body 22 starts to work, sucking in the cold water from the water supply pipe 12, heating it through the heating pump body 21, and then delivering it to the heating end through the output sleeve 24 and the output pipe 14. At the same time, the heat of the external heat source is continuously introduced into the heating pump body 21 through the heat conduction pipe 15, the heat conduction pipe sleeve 26, and the heat flow inlet head 25 to improve the anti-freezing effect.

[0034] Embodiment Four:

[0035] A vibration frame 41 is provided at the top of the delivery pump body 22. A vibration pump 42 is installed on the vibration frame 41. A vibration rod 43 is installed at the driving end of the vibration pump 42. The vibrating end of the vibration rod 43 penetrates into the inner cavity of the delivery pump body 22.

[0036] The vibration pump 42 drives the vibration rod 43 to move, keeping the water flow in the inner cavities of the delivery pump body 22 and the heat supply pump body 21 in a flowing state, increasing the flow velocity of the water flow. In cooperation with the above structure, preheating the liquid can ensure that the liquid will not freeze due to too low temperature during transportation, ensuring the normal operation of the delivery pump body 22.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

[0038] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution.
