Embodiment 1

[0053] like Figure 1-Figure 4 , Figure 6-Figure 7 As shown, a counterweight device with adjustable pipeline counterweight is provided in this embodiment, and the counterweight device includes:

[0054] The double-layer casing is set on the outside of the pipeline 1 that needs counterweight along the direction of the pipeline. The inner diameter of the double-layer casing is larger than the outer diameter of the pipeline 1 that needs counterweight. 101, an annular counterweight cavity is formed between the inner tube 102 and the outer tube 101, and the pipeline requiring counterweight extends in the inner tube 102;

[0055] A partition assembly, arranged between the double-layer sleeves, is used to separate the annular weight cavity 4 into multiple sub-weight cavities;

[0056] A vibration detection device is used to detect the pipeline 1 to determine the position of the pipeline 1 to be counterweighted;

[0057] The magnetic weight material can be filled in the ring-shaped ...

Embodiment 2

[0065] In this embodiment, a control method for adjusting the pipeline counterweight is provided. The control method is used to control any counterweight device in Embodiment 1 to adjust the pipeline 1's counterweight. The control method includes: detecting the pipeline 1, selecting the position where the maximum vibration value occurs in the pipeline 1 as the position to be counterweighted; determining the sub-weight cavity corresponding to the position to be counterweighted according to the position to be counterweighted; The magnetic top cover 3 is energized to absorb the magnetic counterweight material into the corresponding sub-weight cavity.

[0066] In some optional ways, energizing the magnetic suction top cover 3 to absorb the magnetic counterweight material into the corresponding sub-weight cavity includes: opening the sub-weight cavity where the magnetic counterweight material is located to the corresponding sub-weight cavity; The circulation hole 8 on the partition...

Abstract

The invention discloses a counterweight device and control method capable of adjusting a pipeline counterweight as well as an air conditioner. The counterweight device comprises a double-layer sleeve, partition plate assemblies, a magnetic counterweight material and a magnetic attraction top cover; the double-layer sleeve is used for being arranged on a pipeline needing counterweight in a sleeving mode, wherein the inner diameter of the double-layer sleeve is larger than the outer diameter of the pipeline needing counterweight, the double-layer sleeve is composed of an inner pipe and an outer pipe, an annular counterweight cavity is formed between the inner pipe and the outer pipe, and the pipeline needing counterweight extends in the inner pipe; the plurality of partition plate assemblies are arranged in the extending direction of the double-layer sleeve, the plurality of partition plate assemblies divide the annular counterweight cavity into a plurality of sub counterweight cavities in the extending direction of the double-layer sleeve, and every two adjacent sub counterweight cavities can be opened or closed according to the transfer requirement of the magnetic counterweight material; and one of the plurality of sub counterweight cavities is filled with the magnetic counterweight material in a transferable mode, and the magnetic attraction top cover is arranged at the end part of the sleeve and is used for providing a magnetic attraction force required by the magnetic counterweight material to transfer among the plurality of sub counterweight cavities.

Description

technical field [0001] The invention relates to the technical field of pipeline damping, in particular to a counterweight device and a control method for adjusting the pipeline counterweight, and an air conditioner. Background technique [0002] At present, in order to avoid pipeline resonance, counterweights are usually placed on the pipeline to change the natural frequency of the pipeline. The position of the counterweight on the pipeline will affect the way the fixed frequency of the pipeline is changed. At present, most household air-conditioning pipelines use rubber blocks or damping blocks to paste and fix them at a certain position in the pipeline. Considering that the excitation of the pipeline changes with the change of the operating frequency of the compressor, the fixed frequency of the pipeline excited Change. Therefore, when the position of the counterweight is fixed, only a certain stage of pipeline fixed frequency can be improved, and the improvement of other...
