Hanging and washing device for field biological membrane collector

Abstract

The invention relates to a hanging and washing device for a field biological membrane collector, which is composed of a collecting vehicle and a washing device. The collecting vehicle is composed of a hook (1), a buoy (2), a roller (3), a water-proof line (4), a telescopic arm (5), a wire winding shaft (6), a handle (7), a support frame (8), a rotating shaft (9), a blind bolt (10), a location circular disc (11), a chassis truck (12) and a horizontal adjusting lead screw (13). The washing device is composed of an ultrasonic cleaning instrument (14), a switch (15), a water pump (16), a water discharging pipe (17) and a chassis (18). The cleaning instrument and the water pump are fixed on the chassis through screws, and then the whole device is fixed on the collecting vehicle. The hanging and washing device for the field biological membrane collector is mainly used for hanging the field biological membrane collector and achieving field washing of a biological membrane, and can be widely applied to different valleys to obtain biological membranes with high quality and perform ecological monitoring. Compared with the prior art, the hanging and washing device for the field biological membrane collector can accurately collect biological membranes of different water depth and finish washing in the field, enables the collector to be hung and taken easily, can adjust the distance between the collector and a bank, ensures that a sampling device is horizontal under complex landform conditions, and is convenient to move.

Description

Technical field [0001] The invention relates to the field of environmental pollution monitoring and evaluation and ecological restoration, and is used for ecological monitoring with biofilm as the object, and can realize the suspension and elution of the biofilm collector in the rapid natural water body in the wild, and complete the collection of the biofilm. Background technique [0002] The existing biota in water bodies are the result of long-term geographic changes and biological evolution. The most direct and effective way to monitor and evaluate the health of aquatic ecosystems is to monitor the biological conditions in the ecosystem. Compared with chemical or physical testing, biological communities are a comprehensive and direct response to various chemical, physical, and biological factors in water bodies, and can better reflect the health of aquatic ecosystems. Therefore, the biological evaluation method has become an important means to evaluate the health of the ecosys...

Problems solved by technology

[0005] (1) The instrument is mostly used for laboratory cultivation and monitoring, and it is inconvenient to cultivate and extract biofilms in the field; (2) Since the structure and function of water biofilms are closely related to water depth, light intensity and temperature, biofilms at different water depths can provide Important ecological information serves for management, but the existing biofilm cultivation and collection devices cannot meet the requirements of convenient field operation and collection of biofilms in different water depths at the same time
