[0002] An air handling unit is a unit formed by integrally installing air treatment components such as an air filter, a surface cooler, a heater, and a humidifier in a vertical / horizontal cabinet. It does not have a refrigerating machine itself and is supplied with cold and hot water by a centralized cold and heat source. According to the external static pressure, it can be divided into two types: one is with a relatively large external static pressure and can be connected to an air duct; the other is with a relatively small external static pressure and generally not connected to an air duct. During the installation and use process of the air handling unit, it needs to be supported by a base

[0003] The existing base structure of the air handling unit is generally fixed, and the components are fixed and limited by welding, resulting in the base of the air handling unit being easily corroded during long-term use, thus causing the base to deform. At the same time, when a local damage occurs to the base, the whole needs to be replaced, resulting in a relatively high overall use cost and greatly increasing the difficulty of production and manufacturing Content of the Utility Model

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, the utility model provides a technical solution: a base system for a general combined air handling unit, including an expandable general rod 10 that forms a transverse rod and a longitudinal rod 12 system. The annular foundation of the base system is composed of the transverse rod, the longitudinal rod, and their connecting members that form the base foundation. This foundation can be expanded according to the different functional sections set in the combined air handling unit. When expanding, different modular rods are selected according to the length requirements of different functional sections to form the base system of the combined air handling unit, improving the overall flexibility of the base system. A longitudinal rod 12 is inserted and combined at the middle connection of the general rod 10, which can increase the overall structural strength of the base system, making the stability and reliability of installation support better. Angle connectors 1 are provided at all four corners where the general rods 10 are connected to each other. When a local part of the base component is damaged, it can be disassembled and replaced locally according to the actual situation, avoiding discarding and replacing all of them, effectively reducing the overall use cost and at the same time reducing the complexity of production and manufacturing. Straight connectors 3 are provided at the end connections of the longitudinal rod 12 and the general rod 10. Anti-detachment blocks 9 are arranged in the cavity of the general rod 10 to ensure the effective connection between the bracket for fixing the upper equipment and components and the modular base rod, as well as the convenience and reliability during the connection operation. Positioning bolts 8 are inserted through the surfaces of the anti-detachment block 9 and the general rod 10 correspondingly. Stainless steel rivet nuts 7 are movably sleeved on the surfaces of the positioning bolts 8. The general rod 10 and the longitudinal rod 12 are spliced and combined with each other through the angle connector 1 and the straight connector 3 to form a complete general base system, ensuring the integrity of the base system and no welding operation during the splicing process. Moreover, the angle connector 1 and the straight connector 3 are inserted and positioned with the general rod 10 and the longitudinal rod 12 through the insertion bolts 4 and the stainless steel flange nuts 5. All connections between the base, the upper attached equipment, and components in this system use bolts and self-tapping screws, and there is no welding operation during the assembly process, ensuring that the system does not generate welding corrosion and thermal deformation.

[0021] On one side of the angle connector 1, a corner fixing member 2 is provided on the surface of the universal rod 10. Universalized mounting holes for connection and positioning are correspondingly formed on the surfaces of the universal rod 10 and the angle connector 1. The universal rod 10 is made of cold-formed square hollow steel, and the size specification of the universal rod 10 is set to 50*50, which can effectively maintain the strength of connection and positioning and avoid the phenomenon of fracture and detachment during long-term use. The universal rod 10, the angle connector 1, the direct connection member 3, the insertion bolt 4, and the corner fixing member 2 are all fixed by stainless steel self-tapping screws 6, which are used for the 90-degree shaping of the angle connector 01 and the firm connection with the air-conditioning box bottom plate, ensuring the connection accuracy and reliability of the system. The stainless steel self-tapping screws 6 are cross-recessed pan head self-tapping screws, the stainless steel rivet nuts 7 are flat head rivet nuts, the positioning bolts 8 and the insertion bolts 4 are all hexagon head full-thread bolts, and hollow holes 11 are arranged on the surfaces of the longitudinal rod 12 and the universal rod 10, which can reduce the material and weight of the overall structure, and further reduce the manufacturing cost and installation difficulty.

[0022] Working principle: When the air conditioner needs to be installed and used, the universal rods 10 can be assembled and spliced. The angle connector 1 and the direct connection member 3 are spliced with the insertion bolt 4 and the stainless steel flange nut 5. The universalized module base rod 10, the angle connector 1, the direct connection member 3, and the insertion bolt 4 are spliced and combined with the air-conditioning box bottom plate, and they are fixed to the air-conditioning box bottom plate through the corner fixing member 2 with stainless steel self-tapping screws 6. To connect the equipment bracket and the base, it is necessary to connect and fasten with the anti-slip block 9 and the stainless steel rivet nut 7 and the positioning bolt 8 fixed thereon, ensuring the effective connection between the bracket for fixing the upper equipment and components and the modular base rod and the convenience and reliability during the connection operation. During the installation process, the combination of the positioning bolt 8 and the stainless steel rivet nut 7 will not slip to the bottom of the modular base rod, causing the phenomenon of inability to connect. At the same time, it is ensured that the nut used to connect with the positioning bolt 8 does not slip and cause the fastening failure phenomenon, thus forming a complete universal base system. During daily use, it can avoid corrosion and thermal deformation caused by welding. At the same time, by combining and splicing the structures with bolts and modularization, it replaces the traditional welded fixed installation. When a local damage occurs to the base components, they can be disassembled and replaced locally according to the actual situation, avoiding discarding and replacing all of them.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
