Abstract

The invention relates to a floating floor device applied to water body ecological restoration. According to the technical scheme, the floating floor device applied to water body ecological restoration is characterized by comprising control columns, a heat preservation hood, a heat preservation enclosure ecosystem and a floating floor, wherein at least three control columns are available; the heat preservation hood is made of a light permeable film and is arranged above the control columns through support rods so as to form a conical hood; the lower side of the heat preservation hood is parallel to the top ends of the control columns; the heat preservation enclosure ecosystem surrounds at the periphery of the control columns through the cooperation of the control columns; the lower side surface of the heat preservation enclosure ecosystem is contacted with mud at the bottom of a water body; the upper side surface of the heat preservation enclosure ecosystem is parallel to the top ends of the control columns; and the floating floor is on the water level inside a relative sealed chamber. By adopting the scheme, the problems that in the conventional opened floating floor, plants hardly grow in winter and are easily affected by external pollution resources are effectively solved, the growth of aquatic plants on the floating floor is well prompted, and the purification of the water body is effectively realized.

Example Embodiment

[0012] Such as figure 1 As shown, a floating bed device for ecological restoration of water bodies includes a light-transmitting thermal insulation cover 1, a control pile 3, a thermal insulation enclosure 4 and a floating bed 2. Among them, the light-transmitting heat-preserving cover 1 is made of a transparent pp plastic film with a thickness of 6mm, and the middle of the plastic film is a closed air layer, so that the heat insulation effect of the air layer and the light transmission effect of the transparent plastic are used to keep heat The cover has the functions of heat preservation and light transmission. The heat preservation cover is provided with support rods 11 that play a supporting role. The support rods 11 are inserted into the jacks at the upper end of the control pile 3, thereby fixing the heat preservation cover 1 above the control pile 3 , There are two support rods 11 of the thermal insulation cover 1, which are made of stainless steel and have a diameter of 10mm; the control pile 3 can be made of rubber with a diameter of 10cm. The number of control piles 3 selected for a single floating bed device during field implementation is four. Its length is 2m, the bottom end of the control pile 3 is inserted into the bottom mud of the water body for 50cm, and the top end of the control pile 3 is exposed about 30 cm above the normal water level. There are 3 nylon cable sets around the body of each control pile 3 , The thermal insulation enclosure 4 can be fixed on the control pile 3; the thermal insulation enclosure 4 is made of pp plastic film with thermal insulation cotton inside, with a thickness of 11.2cm, which is glued on the plastic film at the position of the control pile 3. It has a fixed buckle and is fixed on the control pile by connecting with the cable sleeve on the control pile 3. The thermal insulation enclosure 4 separates the water body inside the enclosure from the surrounding water body through the function of enclosing and partitioning. A relatively independent body of water is formed inside. In this example, the water area enclosed by the insulation enclosure 4 and the control pile 3 is 3m×5m, the water depth inside the enclosure is 1.2m, and the bottom of the insulation enclosure 4 is close to the mud surface of the water bottom. The height of the light-transmitting heat-preserving cover 1 is 1.0m, and the heat-preserving enclosure 4 and the light-transmitting heat-preserving cover 1 can be linked to each other through a zipper, so that the floating bed device forms a continuous whole to ensure the heat preservation function of the floating bed device; Inside the enclosed water body, there is a floating bed 2. The floating bed 2 can be made of bamboo and filled with plant fibers. The size is 2.5m×4.5m×20cm, and it is fixed on the control pile 3 by ropes. The floating bed is planted with canna and cress Aquatic plants such as iris and iris achieve the purification effect of the water quality inside the enclosure through the biofilm grown by the roots of the aquatic plant and the absorption of the plant. In addition, the above-mentioned floating bed device is periodically replaced manually, and the zipper between the enclosure and the thermal insulation cover is unzipped every 15 days, and the enclosure is pulled down to achieve the water quality of the enclosure between the internal water body and the surrounding water body through natural water exchange. Exchange, after changing the water, reconnect the enclosure insulation cover and the insulation enclosure to make it have a thermal insulation function. When maintenance activities such as plant harvesting are required, the insulation cover and enclosure can be temporarily dismantled and rebuilt after the construction is completed.
[0013] The device of the invention has the functions of heat preservation, isolation and regular water change, which can solve the shortcomings of the traditional open floating bed device being vulnerable to external pollution sources, poor plant growth in winter, and poor water purification effect.
