[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0035] As Figures 1 to 7 shown, the present invention provides a heat pump installation structure for a geothermal heating system, including:

[0036] A lifting mechanism, the lifting mechanism includes a bearing plate 2 and a pair of relatively arranged mounting bases 1. Both ends of the bearing plate 2 are respectively slidably connected to a mounting base 1. Each mounting base 1 is provided with a driving structure for driving the bearing plate 2 to lift vertically relative to the mounting base 1. An installation space is formed between the pair of mounting bases 1 and above the bearing plate 2 for accommodating the heat pump body 3. At least one side of the bearing plate 2 is provided with a wedge-shaped guide plate 4 extending outward from the installation space;

[0037] A rolling member 5, rotatably connected below the heat pump body 3.

[0038] Specifically, to solve the problem that the labor intensity of maintenance personnel is relatively high when the main unit of the heat pump is removed from the placement groove base and moved subsequently; the heat pump installation structure for the geothermal heating system provided by the present invention has a lifting mechanism. The lifting mechanism can carry the heat pump body 3 through the bearing plate 2, and the lifting mechanism can drive the bearing plate 2 to lift through the driving structure, facilitating the heat pump body 3 placed on the bearing plate 2 to be lifted to the working position, and also facilitating the heat pump body 3 to be lowered to the ground or a position close to the ground. At the same time, in cooperation with the wedge-shaped guide plate 4, it is convenient for the heat pump body 3 to be moved out of or into the bearing plate 2. The rolling members 5 are arranged at the bottom of the heat pump body 3, and when the heat pump body 3 is moved out of or into the bearing plate 2, rolling contact and relative movement are formed between the rolling members 5 and the bearing plate 2 and the wedge-shaped guide plate 4, making the movement and maintenance of the heat pump body 3 very convenient and labor-saving.

[0039] In this embodiment, a pair of mounting seats 1 are connected by a connecting plate. The connecting plate is on the side of the installation space away from the wedge-shaped guide plate 4 and is connected to the outside of the pair of mounting seats 1.

[0040] Specifically, if the wedge-shaped guide plate 4 extends out of the right side of the pair of mounting seats 1, the connecting plate is connected to the left side of the pair of mounting seats 1.

[0041] Optionally, a limiting groove 6 is provided on the surface of one side of the pair of mounting seats 1 close to each other. One outwardly protruding limiting block 7 is respectively provided on both sides below the heat pump body 3. The limiting block 7 is in sliding fit with the limiting groove 6.

[0042] Specifically, when the heat pump body 3 is installed into the installation space, the limiting blocks 7 on both sides below the heat pump body 3 can slide into the limiting groove 6 and form a sliding fit with the limiting groove 6, which does not affect the lifting of the heat pump body 3 and provides a limit for the heat pump body 3, improving the stability of the heat pump body 3.

[0043] In this embodiment, the lower end of the limiting groove 6 is open. During the descending process of the bearing plate 2, it can descend to contact the ground. At this time, a gap is formed between the upper surface of the bearing plate 2 and the lower end of the limiting groove 6. The gap can accommodate the limiting block 7 to pass through. At this time, the heat pump body 3 can directly move towards the wedge-shaped guide plate 4.

[0044] Optionally, an installation frame 8 is provided below the heat pump body 3. The rolling members 5 are rotatably connected to the installation frame 8, and the limiting blocks 7 are arranged on the outside of the installation frame 8.

[0045] Specifically, as Figure 2 shown, the installation frame 8 includes a bottom plate and two vertical plates. The two vertical plates are connected to the bottom plate to form an inverted U shape. The two ends of the rolling members 5 are respectively rotatably connected to one vertical plate, and the limiting blocks 7 are arranged on the sides of the two vertical plates away from each other.

[0046] In this embodiment, the rolling member 5 is a roller, and at least part of the roller is exposed from below the two vertical plates.

[0047] Optionally, the driving structure includes:

[0048] A winding shaft 9 which is rotatably arranged on the outside of the mounting seat 1;

[0049] A driving motor 10, one end of which is connected to one end of the winding shaft 9;

[0050] A traction rope 11, one end of which is connected to the winding shaft 9, and the other end of the traction rope 11 bypasses the top surface of the mounting seat 1 and is connected to the bearing plate 2.

[0051] Specifically, the driving motor 10 can drive the winding shaft 9 to rotate. By the rotation of the winding shaft 9, the traction rope 11 can be wound, thereby pulling up the bearing plate 2 upward, so that the bearing plate 2 and the heat pump body 3 above the bearing plate 2 are lifted. Similarly, when the traction rope 11 is released, the bearing plate 2 and the heat pump body 3 can descend.

[0052] In this embodiment, the winding shaft 9 is connected to the mutually remote sides of the two mounting seats 1 through hinge ears, and the driving motor 10 is mounted on the mounting seat 1 through a motor bracket.

[0053] Optionally, guide grooves 12 are provided on the mutually close side surfaces of a pair of mounting seats 1, and guide blocks 13 are respectively provided at both ends of the bearing plate 2, and the guide blocks 13 are in sliding fit with the guide grooves 12.

[0054] Specifically, the guide blocks 13 on the bearing plate 2 are slidably embedded in the guide grooves 12, and the guide grooves 12 provide a guiding function during lifting and lowering.

[0055] In this embodiment, as Figure 4 and Figure 5 shown, the lower ends of the guide grooves 12 are open, and during the descending process of the bearing plate 2, it can descend to contact the ground. At this time, the limit blocks 7 on the bearing plate 2 are separated from the limit grooves 6, and the guide blocks 13 on the bearing plate 2 are separated from the guide grooves 12.

[0056] In this embodiment, two guide blocks 13 are respectively provided at both ends of the bearing plate 2, and the two guide blocks 13 are respectively located on both sides of a limit block 7.

[0057] Optionally, embedding grooves 14 communicating with the upper ends of the guide grooves 12 are provided on the top surface of the mounting seat 1, the other end of the traction rope 11 is connected to the guide block 13, and the traction rope 11 is slidably embedded in the embedding grooves 14.

[0058] Specifically, when the towing rope 11 bypasses the top of the mounting base 1, the part of the towing rope 11 at the top of the mounting base 1 is located in the embedding groove 14, and the embedding groove 14 provides a limiting function for the towing rope 11.

[0059] Optionally, it further includes a fixing mechanism. The fixing mechanism includes a leg 15 and a limiting sleeve 16. The upper end of the leg 15 is connected to the bottom surface of the mounting base 1. The lower end of the limiting sleeve 16 is used to be fixed on the installation plane, and the lower end of the leg 15 is inserted and matched with the upper end of the limiting sleeve 16.

[0060] Specifically, the lower end of the limiting sleeve 16 can be fixed on the ground, with the ground as the installation plane. At this time, the heat pump body 3 and the lifting mechanism can be lifted together by a hoisting device, and the lower end of the leg 15 can be aligned with the upper end opening of the corresponding limiting sleeve 16, and then the heat pump body 3 and the lifting mechanism are lowered together, and the lifting mechanism is inserted into the limiting sleeve 16 to realize the positioning of the lifting mechanism and the heat pump body 3.

[0061] Optionally, through grooves 17 are respectively formed on a pair of opposite side walls of the limiting sleeve 16. Lock arms 18 are respectively rotatably connected to a pair of opposite side walls of the leg 15. The lower end of the lock arm 18 is rotatably connected to the leg 15. A lock groove 19 is arranged at the upper end of the lock arm 18. The through groove 17 can accommodate the lock arm 18 to pass through. A U-shaped lock rod 20 is arranged on the side wall of the limiting sleeve 16 below the through groove 17. The two ends of the lock rod 20 are rotatably connected to the limiting sleeve 16, and the middle part of the lock rod 20 is used to be embedded in the lock groove 19.

[0062] Specifically, as Figure 6 shown, the lock arm 18 hinged on the leg 15 can rotate and can pass through the through groove 17 to form an open state. And in the open state, the outer side of the lower end of the lock arm 18 can contact with the lower groove wall of the through groove 17, and the lower groove wall of the through groove 17 forms a rotational limit for the lock arm 18 to limit the continuous opening of the lock arm 18. At this time, the lock rod 20 is rotated, and the middle part of the lock rod 20 is embedded in the lock groove 19 at the upper end of the lock arm 18 to fix the lock arm 18. In this way, the leg 15 cannot be pulled out upward from the limiting sleeve 16, realizing the fixation of the leg 15, and further realizing the fixation of the lifting mechanism and the heat pump body 3.

[0063] Optionally, accommodating grooves 21 are respectively arranged on a pair of opposite side walls of the leg 15. Each lock arm 18 is movably embedded in an accommodating groove 21. The lower end of the lock arm 18 is rotatably connected to the leg 15 through a hinge shaft 22. A torsion spring is arranged on the hinge shaft 22, and the torsion spring is used to apply a torque to the lock arm 18, and the torque can cause the lock arm 18 to rotate and thus open outward from the leg 15.

[0064] Specifically, as Figure 7As shown, the receiving groove 21 can accommodate the lock arm 18 in the retracted state, so that the lock arm 18 does not protrude from the surface of the leg 15. At this time, the leg 15 can be pulled out upward from the limit sleeve 16. The setting of the torsion spring enables the lock arm 18 to automatically pass through the through groove 17 and form an open state after the leg 15 is inserted into the limit sleeve 16, which is convenient for installation and fixation.

[0065] The present invention also provides a heat pump, comprising:

[0066] The heat pump body 3;

[0067] The above heat pump installation structure for a geothermal heating system.

[0068] In this embodiment, as Figure 2 shown, a plurality of air outlets 23 are provided at the top of the heat pump body 3, and fans are provided in the air outlets 23. The heat pump body 3 is the main unit of the heat pump. It mainly works through a compressor to reduce the temperature of the circulating water in summer and increase the temperature of the circulating water in winter to meet the needs of indoor cooling and heating. By turning on the fans, the heat inside the heat pump body can be dissipated along the air outlets 23.

[0069] Specifically, during the actual installation and disassembly of the primary heat pump, first, the limit sleeve 16 is fixed on the designated ground. Then, the heat pump body 3 together with the lifting mechanism is lifted, and the support legs 15 are aligned with the limit sleeve 16. After that, the heat pump body 3 and the lifting mechanism are lowered. At this time, the support legs 15 will enter the limit sleeve 16. During the process of the support legs 15 entering the limit sleeve 16, the limit sleeve 16 will limit the locking arm 18, causing the locking arm 18 to contract in the receiving groove 21. When the support legs 15 are in place in the limit sleeve 16, the through groove 17 is aligned with the receiving groove 21. Under the action of the torsion spring, the locking arm 18 is driven to rotate, causing the locking arm 18 to pop out from the receiving groove 21 and the through groove 17 to form an open state. At this time, rotate the locking rod 20 and lock the locking rod 20 in the locking groove 19 of the locking arm 18 to complete the installation and fixation of the heat pump. Then, the heat pump body 3 can be connected to the pipeline in the geothermal heating system. After the connection, it can be used normally. By the work of the compressor, the temperature of the circulating water is reduced in summer and increased in winter to meet the needs of indoor cooling and heating. During use, by turning on the fan, the heat inside the heat pump body 3 can be dissipated along the air outlet 23. When the heat pump body 3 needs to be repaired, first, turn on the drive motor 10. The drive motor 10 drives the winding shaft 9 to rotate, and the winding shaft 9 releases the traction rope 11. At this time, the bearing plate 2 will descend along the guide groove 12 and drive the heat pump body 3 to descend together. When the bottom of the bearing plate 2 touches the ground, the limit blocks 7 on both sides of the mounting frame 8 below the heat pump body 3 will slide out of the limit groove 6. At this time, the limit on the mounting frame 8 disappears, and the heat pump body 3 can be pushed to move through the rolling of the rolling components 5. After passing through the wedge-shaped guide plate 4, it is moved to the designated position for repair. After the repair is completed, the heat pump body 3 is pushed onto the bearing plate 2, and the limit blocks 7 are aligned with the limit groove 6. Then, control the drive motor 10 to reverse, use the winding shaft 9 to wind up the traction rope 11, drive the bearing plate 2 to rise. At this time, the limit blocks 7 on the mounting frame 8 will enter the limit groove 6. The bearing plate 2 is guided through the guide groove 12, and the mounting frame 8 and the heat pump body 3 are limited through the limit groove 6, and then the heat pump body 3 can be used normally. When the lifting mechanism needs to be disassembled, rotate the locking rod 20 and turn it out of the locking groove 19. Then, manually press the locking arm 18 with a tool to make it retract into the receiving groove 21. Then, lift the heat pump body 3 to a short height, use the limit sleeve 16 to limit the locking arm 18. Then, take out the tool from the receiving groove 21 and continue to lift the heat pump body 3 to complete the disassembly work.

[0070] The embodiments of the present invention have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
