Description

Technical Field

[0001] This utility model relates to the field of air conditioning cleaning technology, and in particular to an automatic descaling device for the water tank of a dual-cold-source evaporative condensing air conditioner. Background Technology

[0002] Dual-source evaporative condensing air conditioners are highly efficient and energy-saving air conditioning systems that combine evaporative cooling and mechanical refrigeration technologies. They are suitable for scenarios requiring high-reliability cooling, such as data centers, communication base stations, and industrial plants. Their core advantage lies in their ability to intelligently switch between or combine the two cooling modes based on environmental conditions, significantly reducing energy consumption while ensuring cooling stability. The water tank of the dual-source evaporative condensing air conditioner is the core water storage component of the evaporative cooling system. Serving as the water source for the spray system, it circulates water through a pump to the packing layer or spray device, ensuring continuous evaporative cooling operation. This absorbs heat from the condenser or air, and the heat is carried away through water evaporation, improving condensation efficiency.

[0003] During the long-term operation of a dual-source evaporative condensing air conditioning system, stubborn scale deposits inevitably form on the inner wall of the water tank. These deposits significantly reduce exchange efficiency, thus affecting the condensing performance of the entire air conditioning system. Currently, the common solution to this technical challenge is to completely remove the water tank from the air conditioning unit and manually clean it with a handheld high-pressure water gun. However, this traditional cleaning method has significant operational limitations: the strong reaction force generated by the high-pressure water gun requires the operator to expend considerable physical strength to resist, increasing labor intensity and making it difficult to precisely control the cleaning trajectory, ultimately affecting the consistency of cleaning results and work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic descaling device for a dual-source evaporative condensing air conditioner water tank, in order to solve the problem mentioned in the background art that the existing high-pressure water guns generate a strong reaction force during the cleaning process, requiring operators to expend a lot of physical strength to resist it. This not only increases the labor intensity but also makes it difficult to accurately control the cleaning trajectory, ultimately affecting the consistency of cleaning effect and work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic descaling device for a dual-cold-source evaporative condensing air conditioner water tank, comprising a base plate, a lifting structure provided on the base plate, and an adjustment structure provided on the lifting structure;

[0006] The adjustment structure includes a fixed frame, a rotating frame, an incomplete gear, a first motor, a rotating gear, a rotating shaft, a rotating plate, a driven gear, a second motor, a driving gear, a storage tank, a high-pressure pump, a spray head, and a discharge pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This automatic descaling device for dual-source evaporative condensing air conditioner water tanks, through its adjustable structure and precisely designed dual-motor drive mechanism, achieves intelligent, fully automatic control of the cleaning angle, significantly improving the technical level of water tank descaling operations. Its core advantage lies in its modular transmission structure. Through the incomplete gear and rotating gear meshing system driven by the first motor, combined with the active and driven gear transmission group driven by the second motor, a multi-dimensional linkage adjustment mechanism is constructed, enabling precise compound angle adjustment of the spray head. This innovative dual-power collaborative control system not only completely replaces the traditional manual operation mode but also forms a closed-loop automated cleaning process through the efficient cooperation of the high-pressure pump and the spray head. This ensures cleaning coverage while significantly reducing the labor intensity of operators, and the precision of the mechanical transmission guarantees the stability and consistency of the cleaning effect.

[0015] 2. This automatic descaling device for dual-source evaporative condensing air conditioning water tanks utilizes a motor-driven and screw-driven system to achieve intelligent and precise vertical positioning of the spray head, significantly improving the three-dimensional spatial coverage of the cleaning system. Its innovative design employs a pulley transmission mechanism driven by a third motor, combined with a linear motion module composed of a high-precision screw and sliding frame, constructing a stable and reliable lifting control system. This allows the spray head to achieve stepless height adjustment according to cleaning requirements. This modular lifting solution not only improves the spatial adaptability of the cleaning system but also ensures the uniformity and thoroughness of scale removal at different heights through the smoothness and repeatability of mechanical transmission. This mechanism, together with the angle adjustment system, forms a three-dimensional collaborative control system, constituting a complete spatial trajectory planning capability. This overcomes the randomness and instability of manual adjustment and achieves standardization and optimization of the cleaning process through systematic motion control, providing crucial technical support for the automated maintenance of complex water tank structures.
