Abstract
Устройство для извлечения мейофауны из песчанистых грунтов, отличающееся тем, что для извлечения мейофауны из песчанистых грунтов включает в себя ручной насос 1 для начального нагнетания воздуха в сосуд 2 с притертой резиновой пробкой и двумя отводными трубками, высокогорлую колбу 3 с притертой резиновой пробкой и двумя отводными трубками; стеклянную воронку 4 с фильтром 5 и сливной стакан 6, помещенные на штатив 7.A device for extracting meiofauna from sandy soils, characterized in that for extracting meiofauna from sandy soils it includes a hand pump 1 for the initial injection of air into a vessel 2 with a ground rubber stopper and two bypass tubes, a high neck flask 3 with a ground rubber stopper and two bypass handsets; a glass funnel 4 with a filter 5 and a drain cup 6 placed on a tripod 7.
Description
Полезная модель относится к гидробиологическому оборудованию, предназначенному для извлечения мейобентоса (донных беспозвоночных размером 100-500 мкм) из песчанистых грунтов.The utility model relates to hydrobiological equipment designed to extract meiobenthos (bottom invertebrates of 100-500 microns in size) from sandy soils.
Известен способ, когда сепарационная воронка, где происходит взмучивание субстрата, имеет поток воды снизу, с отводной трубкой, расположенной в верхней части (1).A known method is when the separation funnel, where the substrate is stirred up, has a flow of water from below, with a drain pipe located in the upper part (1).
Известен способ получения восходящих токов воды с использованием длинной стеклянной трубки, доходящей до субстрата на дне сепарационной колбы (2, 3).A known method of producing upward currents of water using a long glass tube reaching the substrate at the bottom of the separation flask (2, 3).
Недостаток этих способов заключается в том, что для их работы требуется проточная (водопроводная) вода. В полевых условиях использование таких установок не всегда возможно.The disadvantage of these methods is that their work requires running (tap) water. In the field, the use of such installations is not always possible.
Задачей полезной модели является создание устройства для извлечения мейофауны из песчанистых грунтов в полевых условиях.The objective of the utility model is to create a device for extracting meiofauna from sandy soils in the field.
Поставленная задача решается путем использования устройства (рис.1), включающего в себя ручной насос 1 для начального нагнетания воздуха в сосуд 2 (с притертой резиновой пробкой и двумя отводными трубками), высокогорлую колбу 3 (с притертой резиновой пробкой и двумя отводными трубками), стеклянную воронку 4 с фильтром 5 и сливной стакан 6, помещаемые на штатив 7.The problem is solved by using a device (Fig. 1), which includes a hand pump 1 for the initial injection of air into the vessel 2 (with a ground rubber stopper and two bypass tubes), a high-neck flask 3 (with a ground rubber stopper and two bypass tubes), a glass funnel 4 with a filter 5 and a drain cup 6, placed on a tripod 7.
Вода, нагнетаемая в колбу 3 из сосуда 2 после инициации потока насосом 1, взмучивает субстрат (пробу песчанистого грунта) в колбе 3, вымывая имеющие меньшую массу по отношению к субстрату организмы мейобентоса, которые попадают по отводной трубке в воронку 4 на фильтр 5, где задерживаются.Water injected into the flask 3 from the vessel 2 after the pump 1 initiates the flow, stirs up the substrate (sandy soil sample) in the flask 3, washing out the meiobenthos organisms that have a lower mass relative to the substrate, which enter the funnel 4 through the drain pipe 4, where are delayed.
