[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an air source heat pump heating device is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, an air source heat pump heating device according to an embodiment of the present invention includes a heat pump host 1, a plurality of fans 2 connected to the top of the heat pump host 1, a base 3 provided at the bottom of the heat pump host 1, a plurality of mounting brackets 4 provided at the top of the base 3 and at the corner of the heat pump host 1, and a controller 5 provided on one side of the mounting bracket 4; a snow removal frame 6 is fitted on the outside of the heat pump host 1 and is snapped into the mounting bracket 4; the bottom of the snow removal frame 6 is movably connected to the top of the base 3 through a lifting mechanism 7 for scraping frost and snow off the side of the heat pump host 1; a flip-top mechanism 8 that cooperates with the lifting mechanism 7 is provided at the top of the mounting bracket 4 for removing frost and snow off the top of the heat pump host 1; and a plurality of protective nets 9 are provided on the front of the heat pump host 1.

[0031] With the cooperation of the base 3, the mounting bracket 4, the snow removal frame 6, the lifting mechanism 7, the turnover mechanism 8 and the protective net 9, the entire system can effectively protect the heat pump host 1 from frost and snow in frosty and snowy weather. When frost and snow accumulate, the lifting mechanism 7 starts to work, drives the snow removal frame 6 connected thereto to move up and down along the side of the heat pump host 1, and removes the frost and snow attached to the side of the heat pump host 1 through scraping action. Due to the unique louvered design of the protective net 9, not only can it effectively block the frost and snow from the outside from directly entering the inside of the heat pump host 1, but also can smoothly drain the water generated in the snow removal process, avoiding potential damage caused by water retention. When the lifting mechanism 7 completes the side snow removal and reaches the highest position, it will drive the turnover mechanism 8 to turn over, cleaning the frost and snow accumulated on the top. It ensures that the top of the heat pump host 1 is not affected by frost and snow, maintains the best operating state of the equipment, thereby improving energy efficiency and prolonging service life.

[0032] It should be noted that in specific applications, the inside of the heat pump host 1 is mainly composed of four core components, namely compressor, evaporator, condenser and throttling device (such as expansion valve).

[0033] In one embodiment, for the mounting bracket 4, a strip-shaped groove 10 is formed in the inside of each of the two groups of mounting brackets 4 and away from the side of the controller 5, ensuring that the snow removal frame 6 can realize stable guiding and limiting effect through the strip-shaped groove 10 when moving up and down.

[0034] In one embodiment, for the lifting mechanism 7, the lifting mechanism 7 includes a connecting rod assembly 701 arranged between the snow removal frame 6 and the base 3; the bottom of the snow removal frame 6 and the top of the base 3 are both provided with a first rectangular groove 702 and a second rectangular groove 703 matched with the connecting rod assembly 701; the side of the snow removal frame 6 and the side of the base 3 and inside the first rectangular groove 702 and the second rectangular groove 703 are both provided with a limiting circular hole 704 and a limiting groove 705 matched with the connecting rod assembly 701; the mounting bracket 4 is provided with a pneumatic cylinder 706 on one side, the output end of the pneumatic cylinder 706 is connected with the connecting rod assembly 701, the connecting rod assembly 701 is of a shearing structure and is composed of multiple connecting rods 7011 intersecting to form a parallelogram; the middle of the two groups of connecting rods 7011 is rotatably matched through a pin shaft, the end portions of the two adjacent groups of connecting rods 7011 are movably connected through a pin shaft, the first rectangular groove 702 and the second rectangular groove 703 are arranged in a staggered manner, ensuring the accuracy of the movement track, so that the snow removal frame 6 can accurately complete the lifting action and effectively remove the frost and snow on the side of the heat pump host 1.

[0035] The specific working principle of the lifting mechanism 7 is as follows: When the cylinders 706 at both ends are started simultaneously, the extension and retraction motion of their output ends is transmitted to the connecting rod assembly 701. The connecting rod assembly 701 is a shear-type structure, composed of multiple sets of connecting rods 7011 intersecting each other, with adjacent connecting rods 7011 being movably connected by pins. The extension and retraction of the cylinders 706 drives the connecting rod assembly 701 to extend and retract. When the output end of the cylinder 706 extends, the connecting rod assembly 701 is stretched, pushing the snow removal frame 6 to move upward along the base 3. Since the bottom of the snow removal frame 6 and the top of the base 3 are both provided with a first rectangular groove 702 and a second rectangular groove 703 that cooperate with the connecting rod assembly 701, and the two are staggered, the connecting rod assembly 701 can slide smoothly in the second rectangular groove 703 during the movement without being obstructed. Meanwhile, both the snow removal frame 6 and the base 3, located on one side and inside the first rectangular groove 702 and the second rectangular groove 703, have limiting holes 704 and limiting grooves 705 that cooperate with the connecting rod assembly 701. When the output end of the cylinder 706 retracts, the connecting rod assembly 701 retracts, causing the snow removal frame 6 to move downwards. The limiting holes 704 and limiting grooves 705 limit the connecting rod assembly 701, ensuring the accuracy of its movement trajectory.

[0036] In one embodiment, the flip-top mechanism 8 includes a cover plate 801 mounted on top of the mounting bracket 4. A support column 802 is symmetrically arranged at the bottom of the cover plate 801. A first limiting rod 803 and a second limiting rod 804 are arranged on both sides of the support column 802 from top to bottom. One end of the second limiting rod 804 is connected to a first connecting rod 805. The other end of the first connecting rod 805 is connected to one end of the second connecting rod 806 via a pin. The other end of the second connecting rod 806 is connected to a rotating shaft 807. A gear 808 is connected to the other end of the rotating shaft 807, located inside the strip groove 10. Y-shaped grooves 11 that cooperate with the first limiting rod 803 and the second limiting rod 804 are provided on the side of both sets of mounting brackets 4 away from the controller 5. This not only effectively removes frost and snow from the top of the cover plate 801 but also protects the heat pump host 1 from frost and snow, improving the operating efficiency and reliability of the equipment.

[0037] The specific working principle of the flip-top mechanism 8 is as follows: With the cooperation of the lifting mechanism 7, the frost and snow on the cover plate 801 are flipped and removed. When the lifting mechanism 7 rises, it drives the snow removal frame 6 to rise as well. The rack 12 on the snow removal frame 6 meshes with the gear 808, driving the gear 808 to rotate. The rotation of the gear 808 transmits power through the rotating shaft 807, thereby driving the first connecting rod 805 and the second connecting rod 806 to slide the first limiting rod 803 and the second limiting rod 804 along the upward branch of the Y-shaped groove 11, realizing the first lifting and then flipping of the cover plate 801. When the lifting mechanism 7 descends, it drives the snow removal frame 6 to rise as well. The rack 12 on the snow removal frame 6 meshes with the gear 808, driving the gear 808 to rotate. The rotation of the gear 808 transmits power through the rotating shaft 807, thereby driving the first connecting rod 805 and the second connecting rod 806 to reset the first limiting rod 803 and the second limiting rod 804 along the downward branch of the Y-shaped groove, ensuring a sealed fit of the cover plate.

[0038] In one embodiment, for the snow removal frame 6, a rack 12 that meshes with the gear 808 is provided on one side of the snow removal frame 6 and inside the strip groove 10. This ensures that the snow removal frame 6 can achieve precise transmission through the meshing of the rack 12 and the gear 808 during the up-and-down movement, thus ensuring the stability and reliability of the movement.

[0039] In one embodiment, the protective net 9 includes a circular protective frame 901 disposed on the front of the heat pump host 1. The circular protective frame 901 is provided with a plurality of fan blades 902 arranged linearly inside. The fan blades 902 are set at a 45-degree angle to the horizontal plane to prevent frost and snow from entering the heat pump host 1, thereby avoiding damage that may be caused by water accumulation inside the heat pump host 1 and ensuring the stability of the operation of the heat pump host 1.

[0040] The specific working principle of the protective net 9 is as follows: When the lifting mechanism 7 moves the snow removal frame 6 up and down, it can scrape away the frost and snow on the side of the heat pump host 1. At the same time, because the fan blade 902 adopts an inclined angle design, it effectively prevents external frost and snow from directly entering the interior of the heat pump host 1.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] like Figures 1-7As shown, in practical application, the operator activates cylinder 706 via controller 5, driving lifting mechanism 7 to move snow removal frame 6 up and down (the specific working principle of lifting mechanism 7 is described above), scraping away frost and snow on the side of heat pump unit 1. Water generated during the scraping process flows out through the inclined design of fan blades 902 on protective net 9 (the specific working principle of protective net 9 is described above), preventing it from entering the interior of heat pump unit 1. When lifting mechanism 7 rises to a certain height, it drives snow removal frame 6 to rise as well, thereby driving flip-top mechanism 8 to flip the cover (the specific working principle of flip-top mechanism 8 is described above), effectively removing frost and snow from the top of cover plate 801 and ensuring stable operation of the equipment.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
