Small-sized field wind power testing device and method

Abstract

The invention discloses a small-sized field wind power testing device and method. The device comprises a digital display dynamometer, a wind shield plate, a fixing frame, a supporting rod, a base, rivets, a fixing screw and a braking screw; the digital display dynamometer is fixed in the fixing frame through the fixing screw, the front end of the digital display dynamometer is provided with a wind shield, the lower end of the fixing frame is provided with a U-shaped clamping groove, the upper end of the supporting rod is provided with an upper-end flat pinhead, the U-shaped clamping groove and the upper-end flat pinhead are connected through the braking screw, the lower end of the supporting rod is connected to the base through a thread, and the four corners of the base are provided with rivets. According to the small-sized field wind power testing device and method, the included angle of the fixing frame and the supporting rod is adjustable, so that the device can be stably fixed at any slope zone, a wind power testing experiment can be conducted in a complex terrain, and therefore the test result is better in accordance with practice. The small-sized field wind power testing device is not only convenient to carry and test, but also can guarantee the authenticity and the accuracy of the test result, and the device and method is suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of related testing of field water and soil loss and land desertification, and relates to a small-scale field wind force measurement test device and method. Background technique [0002] In recent years, more and more experts and scholars have carried out experimental research in related fields such as land degradation, desertification, and soil erosion, and the in-situ test experiments of soil erosion disasters have also encountered difficulties in the site. In this kind of research, mastering the wind force is the basic condition for evaluating the movement of soil by wind erosion, and it is also a key technical issue in the in-situ test. For natural slopes in the field, accurately testing the ground wind force in different regions in different seasons and evaluating the loss of regional soil particles is an important indicator for studying wind erosion, and it is also one of the problems to be further solv...

Problems solved by technology

[0003] After reviewing a large number of documents and market surveys, it is shown that there are relatively many test systems related to wind erosion at home and abroad, and most of the tests are indoor simulation tests, and some test devices are mainly based on wind direction, wind speed and surface soil particle migration characteristics. Wind erosion test, but the premise of wind erosion test is to grasp the wind force, blowing erosion direction, etc.

According to the available information, the areas with strong wind erosion are mostly distributed in arid and semi-arid areas with harsh climate conditions. The terrain conditions are complex and changeable. More importantly, most of the areas are eroded mountainous areas. have a certain impact

In addition, the strength of wind erosion mainly depends on the size of the wind. To carry out the test of the size of the wind under various complex terrain conditions in the field, it is necessary to use a portable test device, and the existing test device cannot meet the test requirements due to various reasons in the field. It is also the main purpose of designing the test device
