A Closeable and Openable Small Ecosystem Simulation Experimental Device

Abstract

The invention belongs to the technical field of biological simulation experiments and relates to a sealable and openable type small ecosystem simulation experiment device. A glass cover and a stainless steel box body with the open upper end are placed on a base, sampling holes are evenly formed in the glass cover, the stainless steel box body is provided with sampling holes the same as those in the glass cover, and a support is installed between the glass cover and the stainless steel box body. A xenon lamp tube, an ultraviolet lamp tube and a shower pipe are fixedly installed above the support. A temperature sensor and a humidity sensor are installed on the two sides of the support in an embedded mode, small holes are evenly drilled at the bottom of the stainless steel box body, a filter screen is arranged in the base, an independent water tank is installed on the left side of the base, a water pump is installed in the water tank, and a control panel is installed on the water tank. A power switch, a water pump switch, an ultraviolet lamp switch, a xenon lamp switch and a temperature and humidity display are arranged on the control panel. The water pump is communicated with the stainless steel box body through a water pipe. The sealable and openable type small ecosystem simulation experiment device is simple in structure, convenient to operate, low in cost, environmentally friendly and convenient to popularize and use.

Description

Technical field: [0001] The invention belongs to the technical field of biological simulation experiments, and relates to a small-scale ecosystem simulation experiment equipment, in particular to a small-scale ecosystem simulation experiment device which can be closed or opened. Background technique: [0002] At present, with the rapid development of social economy, the living environment of human beings is suffering from increasingly serious damage, and some persistent organic pollutants (POPs) exceed the standard discharge, resulting in varying degrees of air, soil and water pollution. Therefore, many experts and scholars are committed to The study of POPs aims to reveal its migration and transformation rules in the environment and its degradation mechanism. As we all know, there are many uncontrollable conditions in the natural environment, which affect the scientificity and quantification of research. The emergence of ecological simulation boxes provides opportunities fo...

Problems solved by technology

However, most of the existing ecological simulation boxes are of the vertical cabinet type, such as the biochemical incubators disclosed in CN2015203418993, CN201510092127.5, CN2014206972924, and CN201520089789.2. Open environment, which will change the experimental environment and affect the experimental results; in addition, it is difficult to realize the real simulation of the ecosystem in the existing simulation box, such as the impact of rainfall, surface runoff, infiltration, etc. on the experimental results and the impact of POPs in soil, Air, water, and the migration between plants; and the existing commercially available small ecosystem simulation boxes are expensive, which is not conducive to extensive research work by scientific research institutions
