Stereo restoration device for submerged plants at different water levels with rigid substrates

Abstract

The invention discloses a stereo restoration device for submerged plants at different water levels with rigid substrates. The stereo restoration device comprises a water floating layer, a vertical sample adjusting framework and horizontal slide rails, wherein the vertical sample adjusting framework is connected with a submerged plant so as to control the adjusted submerged plant along the verticaldirection; the water floating layer is connected with the vertical sample adjusting framework, and is used for supporting the vertical sample adjusting framework; the vertical sample adjusting framework is movably connected with the horizontal slide rails; the horizontal slide rails are used for controlling the movement of the vertical sample adjusting framework along the horizontal direction. The stereo restoration device has the advantages that the stereo growth of the submerged plants in the water body with the rigid substrate can be realized, the stability is good, the disturbance by stormy waves is avoided, the water body can be effectively purified within the stereo range, and the submerged plants are artificially controlled; the principle is simple, the cost is low, and the operation is simple.

Description

technical field [0001] The invention relates to the field of water environment research, in particular to a three-dimensional recovery device for submerged plants with different water levels on hard substrates. Background technique [0002] At present, the pollution of large and small lakes and rivers in my country is still relatively serious, especially the existence of various malignant substrates has seriously affected the water ecological balance of lakes and rivers. Planting aquatic plants is an effective bioremediation method for polluted water bodies. Specifically, there are submerged plants, floating leaf plants, emergent plants and floating plants, but in recent years, submerged plants are commonly used. Purification of water quality has always been an effective means, and it can restore eutrophic water bodies by absorbing nitrogen and phosphorus. However, the special water quality of some lakes and rivers has caused the growth and distribution area of ​​submerged ...

Problems solved by technology

And the patents that have been published at present, such as the Chinese invention patent, authorized publication number: CN 203855455 U, publication date: October 01, 2014, disclose a kind of submerged plant planting device, which only meets the requirements of submerged plants in a single position. The planting of plants cannot be controlled horizontally, nor can it be controlled vertically, and it is almost out of manual control, which can easily cause nutrient deficiency or even decline of submerged plants, resulting in secondary pollution

In addition, the Chinese invention patent, authorized announcement number: CN 201777934U, open date: March 30, 2011, discloses a continuously adjustable submerged plant planting net bed, and the working range of the device in the overall horizontal and vertical directions is both It has been controlled to some extent, and the cooperation with manual work has also achieved the goal, but the net bed of the device is completely underwater. First, it is obviously inconvenient to observe the specific position during manual debugging. Direction control cannot achieve sufficient three-dimensional single-part control, only to achieve overall rise or fall, which is not flexible enough, and its movement in the horizontal direction is also limited to a certain extent
