  • Patent number: 11293832
    Abstract: The present invention provides large-amplitude vertical-torsional coupled free vibration testing device for bridges in natural winds, which comprises a rigid model, light-weight high-strength thin strings, linear extension springs, a rigid framework, spring protection tubes, a turntable, a rigid column, a motor, heavy blocks, and rigid thin circular rods. Based on the device, free vibration tests of a bridge deck rigid model can be carried out in natural wind with good conditions, and hence the large-scale wind tunnel device is no longer required. The scaling ratio of the rigid model is no longer limited by the wind tunnel size as in a traditional test, and the scaling ratio can be much larger. Compared with traditional wind tunnel test, the device is more suitable for large-amplitude vibration tests since it can reduce the geometrical nonlinearities of the extension springs and the blocking ratio.

  • Patent number: 10775062
    Abstract: A method for cleaning an air conditioner indoor unit and outdoor unit includes controlling a heat exchanger to enter a self-cleaning mode, adjusting an operating frequency of an air conditioner, an opening of a throttling device, and a corresponding fan speed of the heat exchanger, and maintaining an evaporating temperature of the heat exchanger within a present range to enable a frost process on a surface of the heat exchanger. When a differential pressure of the air conditioner meets a preset condition, a four-way valve changes a direction, switching defrosting to indoor and outdoor heat exchangers. When the differential pressure does not meet the preset condition, the air conditioner is adjusted to meet the preset condition and the four-way valve direction is changed to perform a defrosting switching to the indoor and outdoor heat exchangers.
