Real-time measuring device and measuring system for ice layer thickness of ice pool

Abstract

The invention provides a real-time measuring device and a measuring system for ice layer thickness of an ice pool. A fixing box of a lifting device fixes the lifting device and a measuring and separating device on a wall above an ice pool. The fixing box of the lifting device is also internally provided with a stepping motor, a shaft coupling, a steel pipe U-type pulley, and a vertical bearing pedestal, and other components. The bottom of the fixing box is connected with five extension tubes. A steel wire rope is wound on the steel pipe U-type pulley of the lifting device. The steel wire ropeis connected with the fixing box of the measuring and separating device through the extension tube. The fixing box of the measuring and separating device is also internally provided with a stepping motor, a resistance-type ice thickness measuring instrument, a direction connection base, a shaft coupling, a resistance outer sleeve, a bearing, a bearing supporting plate, and a shockproof pipe clamp,and other components. The device and the system are suitable for real-time measurement of ice layer thickness of a water surface of an ice pool in an ice making process, and are advantaged by convenient measurement, high precision, and real-time measurement of ice layer thicknesses on different positions, and effectively improve efficiency of ice layer thickness measurement of the ice pool in anice making process.

Description

technical field [0001] The invention relates to a real-time measuring device and a measuring system for the thickness of an ice layer in an ice water pool, belonging to the technical field of ice water pool tests. Background technique [0002] The development of ice engineering laboratories at home and abroad has gone through several stages. Ice engineering experiments have been carried out in ice pool laboratories for decades. The ice pool laboratory was built in the former Soviet Union in 1955, and the second cryogenic ice pool laboratory was built in Finland in 1969. The initial development of ice water tanks was slow, small in scale and low in level, and there were few test contents that could be carried out. The main focus was on the navigation performance prediction of ships in ice areas in ice, and the test methods and environmental model ice production methods were not unified. After the 1980s, with the rise of offshore oil development activities in cold sea areas, ...

Problems solved by technology

[0004] At present, the longest strip ice pool in the world measures 90m×12m×3m, and the widest square ice pool measures 40m×40m×2.8m. The length and width of the pool are very large. It is difficult to effectively ensure the uniformity of the thickness of the ice layer on the surface of the ice water pool. In addition, due to the different cooling methods and the performance differences of the test equipment at different locations during the ice making process of the ice water pool, the unevenness of the ice layer thickness is caused. further increase

Furthermore, in the ice water pool, the specific heat capacity and related properties of the test water in the ice water pool are quite different from those of the surrounding pool wall concrete, which further aggravates the inhomogeneity between the ice layer and the middle of the ice layer, thus affecting the test results. have a big impact
