Description

Technical Field

[0001] The invention relates to the technical field of ecological floating islands for water body improvement, and in particular to an ecological landscape floating island. Background Art

[0002] The ecological floating island is based on an aquatic plant, uses the principles of soilless cultivation technology, uses polymer materials as carriers and matrices, applies the principle of symbiotic relationships between species and makes full use of the spatial niche and nutritional niche of water bodies to establish an efficient artificial ecosystem to reduce the pollution load in the water body.

[0003] That is, specially made light biological carriers are spliced, combined and designed into required patterns and areas of different sizes according to different design requirements, and placed in polluted waters. Aquatic (terrestrial) plants that have been screened, domesticated and have strong ability to adsorb organic pollutants are planted in prefabricated floating island carrier planting troughs. These plants grow in polluted waters, and the roots of the plants naturally extend and suspend in the water, adsorbing and absorbing organic pollutants such as N and P in the water, providing living space and attachment conditions for microorganisms in the water, and can also release a compound to inhibit the growth of algae, thereby achieving the purpose of repairing and rebuilding the water ecosystem.

[0004] Ecological floating islands have a unique and complex purification mechanism. They can utilize the biological, chemical and physical effects of the matrix-microorganism-plant complex ecosystem to efficiently treat water through filtration, adsorption, co-precipitation, ion exchange, plant absorption and microbial degradation and decomposition, turning polluted water into clean water. In most cases, the removal rate of biochemical oxygen demand on ecological floating islands is 77.1%, the removal rate of total suspended solids is 82.5%, and the removal rate of phosphorus is 85.9%.

[0005] In addition, the ecological floating island also has ecological landscape functions.

[0006] Through the design of plant variety combination, color matching, spatial layout and other aspects, a floating island landscape is built that is coordinated with the surrounding urban environment and connected with the surrounding urban functional belt, creating a unique and rich spatial experience. The diversity of the plant system is to promote the improvement of the habitat environment, increase the diversity of plant species, improve the ecological integrity, and achieve a landscape with rich plant diversity through reasonable planning and design of plant configuration.

[0007] However, the problems with existing ecological floating islands are: 1. The contradiction between water purification and landscape design. To enhance the efficiency of water purification, as many plant floating islands as possible need to be set up, but this will lose the aesthetics of the design and make the water surface crowded and disordered. Otherwise, it will only be used for viewing, with low purification efficiency and become a formality. 2. The adverse effects of climate change on ecological floating island plants, especially in winter, when low temperatures cause many aquatic plants to wither and die. Moreover, when planting diverse plants, the different growth habits of each plant must be taken into account, such as suitable temperature. 3. In closed rivers and ponds, the water body has no fluidity, resulting in the difficulty of floating island plants only on the water surface to absorb pollutants deposited on the bottom of the water. Summary of the invention

[0008] In order to solve the deficiencies of the above-mentioned technologies, the present invention provides an ecological landscape floating island. The technical solution of the present invention is as follows: an ecological landscape floating island, including a diving box, an air circulation device, a water circulation device, a lifting mechanism and a PLC controller. The diving box includes a box body, a cultivation platform, a lifting mechanism, a sealed top cover, a reflection cover and a driving motor. The box body includes an air inlet, an air outlet, a water inlet, a water outlet and a display opening on the vertical top surface. The cultivation platform is arranged in the box body for vertical sliding cooperation. The cultivation platform includes a planting layer and a waterway located vertically below the planting layer. The lifting mechanism cooperates with the cultivation platform to drive the cultivation platform to be lifted to the display opening or stored in the box body. The water circulation device The device, the waterway and the water inlet and the water outlet are connected by bellows sealing, and the air inlet and the air outlet of the air circulation device are connected by bellows sealing; the capping cover cooperates with the display opening of the box body for rotation and unsealing, the reflection cover is arranged on the side of the landscape floating island facing the shore and is hinged with the box body, the reflection cover includes an arc top surface and a transition surface facing the shore, the surface of the reflection cover is black or dark, and the transition surface is a gradient color, the driving motor is arranged at the hinge of the capping cover and the reflection cover for linkage cooperation, driving the capping cover and the reflection cover to flip; the lifting mechanism cooperates with the diving box to drive the diving box to rise and fall relative to the water surface.

[0009] The above technical solution is adopted to set up as many floating islands as possible and avoid the crowded and messy phenomenon caused by floating islands all over the water surface. Therefore, the diving box is designed as an independent space, which can be opened and closed by the capping cover. Plants are planted in the planting layer of the cultivation platform. The plant roots spread into the waterway through the planting layer. Water and air are introduced and led out through the water circulation device and the air circulation device for plant growth and purification. The relatively closed waterway can protect the growth of microbial communities and avoid being eaten by fish and shrimp.

[0010] Designers can adjust the layout of the floating island according to environmental themes, seasonal changes, and species combinations. They can also adjust the rise and fall of the submersible tank according to real-time needs. For plants that need to be displayed, the submersible tank rises to the water surface, opens the top cover to reveal the display opening, and then raises the cultivation platform to the display opening to display the plants on the water surface.

[0011] As for other plants that are not on display temporarily, the diving box is sealed with a cap, sunk below the water surface, and then blocked by the black or dark color of the reflection cover, so that pedestrians can only see the reflection on the water surface and cannot see the diving box hidden underwater. The gradient color of the transition surface of the reflection cover makes the reflection cover blend into the water more naturally and avoid visual abruptness.

[0012] With this setting, the design can freely arrange the array of ecological landscape floating islands with flexible and varied styles. By planting enough plants, the water purification speed is enhanced.

[0013] A further configuration of the present invention is that the landscape floating island also includes outdoor temperature sensors connected to the PLC controller signals, and the PLC controller controls the lifting mechanism and the driving motor to operate according to the outdoor temperature sensor signals.

[0014] By adopting the above technical solution, the diving box can also be used as a temperature box to protect plants when the outdoor temperature is low, such as in winter and late at night, when there are few tourists, the plants are in low temperature for a long time, which is not conducive to growth and may even wither. Therefore, an outdoor temperature sensor is designed to detect the temperature of the link. When it is too low, the diving box is driven to close and sink to keep the plants warm.

[0015] A further configuration of the present invention is that the landscape floating island also includes an in-box temperature sensor and an electric heater arranged at the air inlet, both of which are connected to the PLC controller signal. The PLC controller controls the start and stop of the electric heater according to the in-box temperature sensor signal.

[0016] By adopting the above technology, the temperature inside the box is compensated by setting up temperature sensors and electric heaters to ensure the survival of plants in cold conditions.

[0017] A further configuration of the present invention is as follows: the landscape floating island includes several groups of submersible boxes, the air circulation device includes an induced draft fan, an air inlet assembly pipeline and several branch pipes, the air inlet assembly pipeline is connected to the induced draft fan, and a plurality of pipe openings are provided corresponding to each submersible box, the air inlet is connected to the air inlet assembly pipeline through the branch pipe, the air outlet is exhausted through the branch pipe, and the induced draft fan is connected to the PLC controller signal.

[0018] By adopting the above technical solution, the air inlet assembly pipeline is divided corresponding to each diving box.

[0019] The present invention is further configured as follows: the water circulation device includes a submersible pump, a water pump, a water inlet assembly pipeline, a plurality of solenoid valves and a plurality of branch pipes. The water inlet assembly pipeline is provided with a plurality of water inlet pipes extending to different water depths. The submersible pump is connected with the water inlet assembly pipeline. The extracted water enters the waterway of the submersible box through each branch pipe. Solenoid valves are provided in the water inlet pipe and in the branch pipe of the water outlet. The branch pipe of the water outlet is connected with the water pump. The submersible pump, the water pump, the solenoid valve and the PLC controller are connected with the signal.

[0020] By adopting the above technical solution, the water inlet assembly pipeline is used to extract water at different depths into the submersible tank, so that the water at the bottom of the river and pond can also be evolved in time.

[0021] The present invention is further configured as follows: a liquid level meter is provided in the water channel of the cultivation platform, and the liquid level meter is connected to the PLC controller signal.

[0022] By adopting the above technical solution, the liquid level meter can avoid water overflow, and the water in the waterway has enough time to contact the plants.

[0023] The present invention is further configured as follows: the lifting mechanism includes a guide rail, a connecting piece and a driving cylinder. The connecting piece is fixedly connected to the box or the cultivation platform and slidingly cooperates with the guide rail. The driving cylinder cooperates with the connecting piece to drive it to rise and fall along the guide rail. The driving cylinder is connected to the PLC controller signal.

[0024] A further configuration of the present invention is that the landscape floating island is arranged at the shore wall of the revetment, and a light bar is arranged on the shore wall along the horizontal height line of the reflection cover.

The water circulation device , the waterway 122 is sealed and connected with the water inlet 113 and the water outlet 114 by a bellows 116, and the air inlet 111 and the air outlet 112 of the air circulation device are sealed and connected by a bellows 116; the capping cover cooperates with the display opening 115 of the box body 11 for rotational unsealing, the reflection cover 14 is arranged on the side of the landscape floating island facing the shore and is hinged with the box body 11, the reflection cover 14 includes an arc top surface and a transition surface 141 facing the shore, the surface of the reflection cover 14 is black or dark, and the transition surface 141 is a gradient color, the driving motor 15 is arranged at the hinge of the capping cover and the reflection cover 14 for linkage cooperation, driving the capping cover and the reflection cover 14 to flip; the lifting mechanism cooperates with the diving box 1 to drive the diving box 1 to rise and fall relative to the water surface.

[0031] In order to set up as many floating islands as possible and avoid the crowded and messy phenomenon caused by floating islands all over the water surface, the diving box 1 is designed as an independent space, which can be opened and closed by the capping cover. Plants are planted in the planting layer 121 of the cultivation platform 12, and the plant roots spread through the planting layer 121 to the waterway 122. Water and air are introduced and led out through the water circulation device and the air circulation device for plant growth and purification.

[0032] The designer can adjust the layout of the floating island according to the environmental theme, seasonal changes, and species matching, and adjust the lifting of the diving box 1 according to real-time needs. If the plant needs to be displayed, the diving box 1 rises to the water surface, opens the top cover to expose the display opening 115, and then raises the cultivation platform 12 to the display opening 115 to display the plant on the water surface.

[0042] The water inlet assembly pipeline extracts water at different depths into the submersible tank 1, so that the water at the bottom of the river and pond can also be evolved in time.

[0043] A liquid level meter 2 is provided in the water channel 122 of the cultivation platform 12 , and the liquid level meter 2 is connected to the PLC controller signal.
