The technical problem to be solved by the utility model is how to measure the snow cover parameters simply and efficiently. The snow parameter measuring instrument is composed of a host and a measuring ruler. The measuring ruler includes a main control shaft, a measuring rod, a dielectric constant sensor and a temperature sensor. There is a scale on the outside of the measuring ruler. The measuring ruler is hollow. The main control shaft is longitudinally inserted into the measuring ruler from the top to the bottom. The main control shaft is cylindrical with a longitudinal gear on the outside. A pair of measuring rods are set on the measuring ruler every certain interval. The pair of measuring rods The measuring rod is at the same horizontal height, it is horizontally embedded in the reserved hole of the measuring ruler, it clamps the main control shaft in the middle, its contact surface with the main control shaft has a longitudinal gear matched with the main control shaft gear, the dielectric constant sensor and the temperature sensor are respectively located at the outer end of a pair of measuring rods, and the guide wire connects the sensor with the main engine. The parameters of snow cover can be measured by inserting the measuring ruler vertically into the bottom of snow cover. There is no need to dig a pit and vertical section, so it is easy to operate.

積雪參數(shù)測(cè)量?jī)x
本技術(shù)涉及積雪科學(xué)研究領(lǐng)域,尤其是積雪參數(shù)的測(cè)量。
技術(shù)介紹
積雪參數(shù)是積雪水文模型、積雪定量遙感中的重要參數(shù),因此,積雪參數(shù)測(cè)量在積雪科學(xué)研究中非常重要。目前,積雪參數(shù)測(cè)量裝置主要是SnowFork雪特性分析儀。SnowFork可測(cè)量共振頻率、衰減度和3分貝帶寬等電學(xué)參數(shù),并利用這些測(cè)量值來(lái)精確地計(jì)算介電常數(shù),然后通過(guò)半經(jīng)驗(yàn)等式計(jì)算雪層密度和液態(tài)水含量。存在的主要問(wèn)題有兩個(gè):1.使用時(shí)需要挖坑和豎直剖面,尤其是積雪深度較大時(shí),測(cè)量過(guò)程耗時(shí)耗力,急需簡(jiǎn)便積雪參數(shù)測(cè)量裝置;2.每次在某一積雪深度插入測(cè)量桿只能測(cè)量一個(gè)點(diǎn)的數(shù)據(jù),測(cè)量效率低。
技術(shù)實(shí)現(xiàn)思路
本技術(shù)所要解決的技術(shù)問(wèn)題是如何簡(jiǎn)便高效地測(cè)量積雪參數(shù)。積雪參數(shù)測(cè)量?jī)x,由主機(jī)和測(cè)量尺組成,測(cè)量尺包括主控軸、測(cè)量桿、介電常數(shù)傳感器和溫度傳感器,測(cè)量尺外側(cè)有刻度,測(cè)量尺為中空的,主控軸從上往下縱向插入測(cè)量尺,主控軸為圓柱形,其外側(cè)有縱向齒輪,測(cè)量尺上每隔一定間隔設(shè)置有一對(duì)測(cè)量桿,該對(duì)測(cè)量桿在同一水平高度,其橫向嵌入測(cè)量尺的預(yù)留孔內(nèi),其將主控軸夾在其中間,其與主控軸接觸面有與主控軸齒輪配套的縱向齒輪,介電常數(shù)傳感器和溫度傳感器分別位于一對(duì)測(cè)量桿的外端,導(dǎo)線將傳感器與主機(jī)相連,使用時(shí),將測(cè)量尺豎直插入積雪底部,旋轉(zhuǎn)主控軸,通過(guò)齒輪傳動(dòng),測(cè)量桿水平移動(dòng)穿出預(yù)留孔,傳感器插入積雪中,在主機(jī)上讀取傳感器測(cè)得的積雪參數(shù)。優(yōu)選地,測(cè)量尺下端為尖端。優(yōu)選地,主控軸上端固定有旋鈕。優(yōu)選地,測(cè)量尺內(nèi)設(shè)置有一對(duì)夾持端,夾持端夾持每對(duì)測(cè)量桿,使得測(cè)量桿與主控軸之間的齒輪保持有效連接。優(yōu)選地,測(cè)量桿的長(zhǎng)度方向平行于測(cè)量尺的 ...
