Embodiment Construction
[0020] The present invention will be further described below in conjunction with the embodiments and with reference to the accompanying drawings.
[0021] See Figure 1-Figure 2 .
[0022] A fixing device for a hot wire anemometer probe, including a base 3, an axis 2 and a slider 1:
[0023] The base 3 has a screw hole in the center as a fixing device for the device;
[0024] The shaft 2 is a cylinder, and the end connected to the base 3 has an external thread, and the shaft 2 is vertically installed on the base 3 through a screw hole;
[0025] The slider 1 includes a first component 12 and a second component 11 connected together by screws; the first component 12 is provided with a through hole, which is sleeved on the shaft through the through hole, and screwed through the screw hole opened on the side 14 is fixed on the shaft 2, the height can be adjusted up and down by loosening the screw 14, and fixed after tightening; the first component 12 and the second component 11...

The invention relates to a fixing device for a probe of a hot-wire anemometer. The fixing device comprises a base, a shaft and a sliding block, wherein a threaded hole is formed in the center of the base which is used as a fixing device body; the shaft is a cylinder, and the end, connected with the base, of the shaft is provided with an outer thread; the shaft is mounted on the base vertically through the threaded hole; the sliding block comprises a first assembly and a second assembly which are connected together via a screw; the first assembly is provided with a through hole, and the first assembly is connected to the shaft in a sleeving mode through the through hole and is fixed to the shaft in the mode that a screw penetrates through a threaded hole formed in the side of the first assembly; the height can be adjusted vertically by unscrewing the screw, and fixation is achieved by screwing the screw; the first assembly and the second assembly are each provided with a semicircular groove; and the grooves of the two assemblies are combined oppositely to form a fixing hole used for fixing a cylindrical metal rod of the probe of the hot-wire anemometer. The fixing device has the advantages that the probe of the hot-wire anemometer can be fixed to the sliding block, and the height can be adjusted at will according to the measuring requirement; and the fixing device can be fixed to any portion of a wind tunnel test section, thereby having great flexibility.
Description
technical field [0001] The invention relates to the technical field of wind tunnel simulation experiments in wind and sand environments, in particular to a fixing device for a probe of a hot-wire anemometer. Background technique [0002] At present, the areas that have been desertified or are undergoing the process of desertification spread over more than 100 countries, affecting the survival and development of 1 billion people. When conducting wind tunnel tests in a sandstorm environment, a hot-wire anemometer is usually used for speed measurement, but the disadvantage of the prior art is that the probe of the hot-wire anemometer cannot be fixed in the wind tunnel simulation experiment. Contents of the invention [0003] The object of the present invention is to provide a fixing device for a probe of a hot wire anemometer aiming at the deficiencies in the prior art. [0004] To achieve the above object, the present invention discloses the following technical solutions: ...
