在含沙量测验中,許多站采用带有進水管和排气管的瓶式采样器,这种仪器目前尚存在一些缺点,例如.①進水管和排水管一般封閉不够嚴密,因而使仪器在没有下放到需要的位置时,就开始進水。②只適用于懸杆安装,因此只能在一定的水潔和流速下才能使用。根据这种情况,筆者設計了一种采样器(暫名为渾江式采样器),現將構造(如圖)說明如下: 1.水样容器用厚洋鉄或鉄瓦制成甲、乙兩个盛裝水样的容器,并可合并为一整体如圖。
In the sediment load test, many stations use bottle samplers with inlet and exhaust pipes. This type of instrument currently has some shortcomings. For example, the inlet pipe and the drain pipe are generally closed tightly, which makes the instrument When there is no decentralization to the desired location, water begins to enter. 2 is only suitable for the installation of a suspension rod, so it can only be used with a certain degree of water and fluid velocity. According to this situation, the author designed a sampler (tentatively named Minjiang-style sampler). Now the structure (as shown in the figure) will be described as follows: 1. The water sample container is made of thick acacia or bran A container filled with water samples can be merged into a single unit.
