Description

Technical Field

[0001] The utility model relates to the technical field of unit installation structures, in particular to an installation structure of an air source heat pump unit. Background Art

[0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It can convert low-level heat energy that cannot be directly used (such as heat contained in air, soil, and water) into high-level heat energy that can be used, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electricity, etc.). Air, as a low-level heat source for heat pumps, is inexhaustible and available everywhere. It can be obtained free of charge. Moreover, the installation and use of air source heat pumps are relatively convenient. Existing air source heat pump units can basically be used normally under normal use conditions and ensure their energy efficiency ratio.

[0003] Through searching, it was found that the installation structure of an air source heat pump unit disclosed in Chinese patent publication number CN 215260635 U proposed that the installation structure of the existing air source heat pump unit mostly uses several groups of bolts to penetrate the support feet and screw them with the preset screw holes, which is inconvenient for the later inspection, maintenance and detection of the unit. After the unit body is slidably installed on the base, the connecting bolts are passed through the connection box, and the cross limit bar is inserted into the cross groove at the same time, so that the connecting bolts and the ratchet are connected as a whole. When the connecting bolts are installed into the screw holes, the ratchet is driven to rotate together, and the ratchet slides in contact with the ratchet. When disassembly is required, the box door is opened, the ratchet is rotated away from the ratchet, and the connecting bolts can be rotated in the opposite direction to disassemble the unit body, which is convenient for the staff to disassemble and prevents malicious disassembly by human beings. However, the above device still connects the unit by bolts, which is not convenient for disassembly and maintenance, and a safety limit assembly is added to the outside of the unit, which does not conform to the existing unit appearance and increases the production cost.

[0004] To this end, we propose an installation structure for an air source heat pump unit to solve the problem that the above-mentioned installation method is inconvenient to disassemble and repair. Utility Model Content
