Problems solved by technology
In engineering applications, there are many wind loads on high-rise buildings, and the research directions are mostly the change model of wind speed at different heights and the theoretical calculation model of wind load; there are relatively few studies on the wind load of floating objects on the water surface, and wind load measurement methods are also rare.

Embodiment Construction
[0009] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific implementations of the present invention will now be described with examples.
[0010] 1. The rod of the floating scale is made of non-absorbent material, hollow inside, and its cross-sectional shape is not limited. Here, a cylindrical rod with a length of 50cm and a diameter of 4mm is used.
[0011] 2. The fixed rod is the same as the floating scale rod, but it is only fixed and does not participate in the calculation process.
[0012] 3. The raw material of the floating objects is feathers, and the shape is not limited. Here, it adopts a disc shape with a diameter of 28cm and a thickness of 1.5cm.
[0013] 4. The measuring ranges of the two spring scales are both 2N. When the scale rod is parallel to the fixed rod, the reading of No. 1 spring is 1.745N, and the reading of No. 2 spring is 1.665N. At this time, the wind speed generated by the bello...

Abstract
The invention relates to a method for measuring the wind load of a tiny floating object in the field of water transport engineering. The method is characterized in that a measurement system is composed of a floating object, a rod and spring scales. The wind load received by a positioning device in the ocean cannot be directly measured, measurement of the wind load needs to be transformed into indoor measurement, a variation pattern is discovered and applied to a practical condition. Under an indoor condition, the stressed area of a research object is limited, and the received wind load is very small. The method provided by the invention is based on a lever amplification principle and combined with an experimental device used for amplifying the wind load, the wind load of the tiny floating object is amplified, and the wind load can be solved indirectly through measuring the amplified force.
Description
technical field [0001] The invention relates to a method for measuring the wind load of tiny floating objects in the field of water transportation engineering, mainly including a measuring system composed of floating objects, rods and spring scales, so as to ensure that the small force can be amplified to the extent that the spring balance can be used for measurement, and at the same time the The invention is also applicable to other shapes of floats. Background technique [0002] In offshore oil, a locator is used to locate the oil spill area. The locator is composed of a floating material and a signal emission source. It is required that the adhesion between the floating material and the oil spill can resist the force of the ocean wind on the locator. It is difficult to measure the adhesion of floating materials in the oil spill area on the sea surface. It needs to be converted to indoor measurement, which will inevitably reduce the size of the floating material used. At t...
