Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, specifically to an air source heat pump that is easy to maintain. Background Technology

[0002] An air source heat pump is an energy-saving device that utilizes high-grade energy to transfer heat from a low-grade heat source (air) to a high-grade heat source. It is a type of heat pump. As the name suggests, a heat pump, like a pump, can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby saving some high-grade energy (such as coal, natural gas, oil, and electricity). Heat pumps are relatively convenient to maintain in daily operations. However, existing air source heat pumps that are easy to maintain are not easy to connect pipes to, which affects the installation and use of the heat pump. Utility Model Content

[0003] The purpose of this invention is to provide an air source heat pump that is easy to maintain, solving the problem that existing air source heat pumps that are easy to maintain are not easy to connect pipes to, thus affecting the installation and use of the heat pump.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air source heat pump that is easy to maintain, comprising a pump body, a sealing ring on the outer surface of the pump body, a support bracket snapped onto the lower surface of the sealing ring, a fixing rod fixedly connected to the lower surface of the support bracket, a base fixedly connected to the bottom end of the fixing rod, a vertical rod fixedly connected to the upper surface of the base, a support structure fixedly connected to the top end of the vertical rod, a connecting ring on the left side of the pump body, a flange overlapping the left side of the connecting ring, the support structure snapped onto the surfaces of the connecting ring and the flange, a fixing ring fixedly connected to the left side of the support structure, a lifting rod movably connected inside the fixing ring, a retaining cover fixedly connected to the right side of the lifting rod, and the retaining cover snapped onto the surfaces of the connecting ring and the flange.

[0006] Furthermore, a fixing block is fixedly connected to the bottom end of the lifting rod, and a spring is sleeved on the surface of the lifting rod.

[0007] Furthermore, the bottom end of the spring is fixedly connected to the upper surface of the fixing block, and the top end of the spring is fixedly connected to the lower surface of the fixing ring.

[0008] Furthermore, a positioning groove is provided on the lower surface of the sealing ring, and a fixing block is engaged inside the positioning groove. The lower surface of the fixing block is fixedly connected to the inner bottom wall of the support bracket.

[0009] Furthermore, a support rod is fixedly connected to the upper surface of the base, and the top end of the support rod overlaps with the lower surface of the pump body.

[0010] This invention provides an air source heat pump that is easy to maintain. It has the following advantages:

[0011] This easy-to-maintain air source heat pump, through the cooperation of vertical rods, support brackets, connecting rings, clamps, flanges, lifting rods, fixing rings, springs, and fixing blocks, facilitates the installation of pipes onto the connecting ring on the left side of the pump body. This solves the problem of existing easy-to-maintain air source heat pumps where it is difficult to connect pipes to them, thus affecting the installation and use of the heat pump.

[0015] like Figure 1-2 As shown, this utility model embodiment provides an air source heat pump that is easy to maintain, including a pump body 1. A sealing ring 2 is provided on the outer surface of the pump body 1. A support bracket 3 is snapped onto the lower surface of the sealing ring 2. A positioning groove 6 is formed on the lower surface of the sealing ring 2. A fixing block 5 is snapped into the interior of the positioning groove 6. The lower surface of the fixing block 5 is fixedly connected to the inner bottom wall of the support bracket 3. A fixing rod 4 is fixedly connected to the lower surface of the support bracket 3. A base 8 is fixedly connected to the bottom end of the fixing rod 4. A support rod 7 is fixedly connected to the upper surface of the base 8. The top end of the support rod 7 overlaps with the lower surface of the pump body 1. A vertical rod 9 is fixedly connected to the upper surface of the base 8. A support structure is fixedly connected to the top end of the vertical rod 9. 10. A connecting ring 11 is provided on the left side of the pump body 1. A flange 13 is overlapped on the left side of the connecting ring 11. A support structure 10 is snapped onto the surface of the connecting ring 11 and the flange 13. A fixing ring 15 is fixedly connected to the left side of the support structure 10. A lifting rod 14 is movably connected inside the fixing ring 15. A fixing block 17 is fixedly connected to the bottom end of the lifting rod 14. A spring 16 is sleeved on the surface of the lifting rod 14. The bottom end of the spring 16 is fixedly connected to the upper surface of the fixing block 17. The top end of the spring 16 is fixedly connected to the lower surface of the fixing ring 15.
