[0031] Example 1:

[0032] Please refer to Figure 1-5 This embodiment provides a medium-space experimental device suitable for research on ecological restoration technology of large lakes, including an ecological enclosure module, a fixing module and a monitoring module;

[0033] The ecological enclosure module includes a PVC enclosure and an ecological mesh 20; the ecological mesh 20 is set in the lake, forming the main area inside; the PVC enclosure is a waterproof PVC rubber enclosure, set in the main area, and separates the test area inside.

[0034] The fixing module is mainly used to support and maintain the shape of the PVC enclosure, and enables mechanized installation and disassembly of the enclosure, reducing the difficulty of enclosure installation and reducing labor costs.

[0035] The monitoring module is installed on top of the fixed module and includes video surveillance and an automatic water quality monitoring device, which is mainly used to monitor changes in water quality within the device in real time.

[0036] Specifically, the PVC enclosure consists of four individual enclosure units 10, each 10m long and 4m high. Each enclosure unit 10 includes a PVC skirt 11, a first float 12, and a first counterweight 13. The PVC skirt 11 is a waterproof PVC rubber skirt, having a top, bottom, and left and right sides. The first float 12 is located at the top of the PVC skirt 11 and is a high-density hollow foam float, allowing the top of the PVC skirt 11 to float on the water surface. The first counterweight 13 is located at the bottom of the PVC skirt 11; the first counterweight 13 can be a stone slab, chain, concrete block, etc., allowing the bottom of the PVC skirt 11 to sink to the lake bottom at a depth of 90°. A third hook and loop fastener is provided on one side of the PVC skirt fabric 11, and a fourth hook and loop fastener is provided on the other side. The third hook and loop fastener and the fourth hook and loop fastener are detachably connected. The third hook and loop fastener and the fourth hook and loop fastener can be connected by Velcro. By connecting adjacent partition units 10 end to end with Velcro, a closed partition area, i.e., the test area, is formed.

[0037] In this embodiment, the PVC skirt fabric 11 of the enclosure unit 10 has a permeable channel 14 with a diameter of 10-30 cm in an area approximately 30 cm from the top. A permeable mesh with a pore size of approximately 2 mm is sewn onto the permeable channel 14. Furthermore, a first hook-and-loop fastener is sewn around the permeable channel 14, and a PVC impermeable enclosure cover is also provided on the permeable channel 14. A second hook-and-loop fastener is sewn around the enclosure cover. The first and second hook-and-loop fasteners are detachably connected and can be secured using Velcro, allowing for flexible opening and closing of the permeable channel 14, facilitating experimental operations.

[0038] An ecological netting 20 is installed around the PVC rubber enclosure. The ecological netting 20 includes a polyethylene skirt, a second float, and a second counterweight. The second float is a high-density strip-shaped rubber-plastic tube, 20cm long and 8cm in diameter, installed on top of the polyethylene skirt to allow it to float on the water surface. The second counterweight is a sinker, installed at the bottom of the polyethylene skirt to allow it to sink to 90° below the lake bottom. The polyethylene skirt is a polyethylene netting with a pore size of 1-2cm. By installing the ecological netting around the PVC enclosure, fish outside the experimental area are intercepted, preventing them from jumping directly into the enclosure area.

[0039] The fixing module consists of a DN80 horizontal galvanized steel pipe connecting rod 30, a vertical DN80 fixing pile 40, and a DN50 anchor pile 50. The DN80 horizontal galvanized steel pipe connecting rod 30 is fixed inside the hollow foam float at the top of the PVC enclosure. A winding device (not shown in the figure) is installed at one end of the connecting rod 30. After the winding device is connected to the engine, it can rotate the horizontal connecting rod 30, rolling the PVC skirt fabric 11 onto the connecting rod 30. The connection between the winding device and the engine can be achieved through a coupling or transmission assembly, thereby allowing the engine to provide power to drive the connecting rod 30 to rotate, as will be understood by those skilled in the art.

[0040] In this embodiment, the fixed pile 40 is vertically arranged, and a groove is welded to the upper end of the fixed pile 40; the connecting rod 30 is rotatably connected in the groove. The bottom of the fixed pile 40 is used to insert into the lake bottom 90, and the top is used to fix the monitoring module (not shown in the figure).

[0041] The fixing module also includes anchor piles 50 and anchor cables 51. One end of the anchor cable 51 is connected to the fixing pile 40, and the other end is fixed to the lake bottom 90 through the anchor pile 50. The anchor cable connects the anchor pile and the fixing pile to prevent the fixing pile from tilting.

[0042] The monitoring module includes a video surveillance device and an automatic water quality monitoring system. The monitoring module is installed on fixed stakes 40 at the four corners of the PVC enclosure, 50cm above the normal water level.

[0043] The space-based experimental device in this embodiment primarily supports the testing of lake ecological restoration technologies. Installed within a large lake, it forms the main experimental area, dividing the test zone and visually demonstrating the impact of the lake's hydrological, hydraulic, sedimentary, and ecological environments on the implementation of the technology, reflecting its applicability in engineering projects. It is highly practical, easy to install and disassemble, reusable, and can replicate the lake's original climate and hydrological characteristics, making it well-suited for pilot-scale experiments in lake ecological restoration technologies.

[0044] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0045] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
