Description

Technical Field

[0001] The utility model relates to the technical field of ecological floating bed transformation, in particular to a movable floating bed device which can reduce bottom mud pollution. Background Art

[0002] In water ecological management projects, an ecological floating bed technology is usually used, mainly for eutrophic water bodies. It uses the principles of ecological engineering to degrade the content of COD, ammonia nitrogen and phosphorus in water. It takes aquatic plants as the main body, applies the principles of soilless cultivation technology, uses polymer materials as carriers and matrices, applies the symbiotic relationship between species, and makes full use of the spatial niche and nutritional niche of the water body, thereby establishing an efficient artificial ecosystem to reduce the pollution load in the water body.

[0003] The matrix filled in the planting pot on the floating bed does not carry any nutrients for plant growth. The growth of emergent plants on the floating bed depends on the nutrients in the polluted water. The nutrients contained in slightly polluted water often cannot meet the normal growth needs of emergent plants on the floating bed. Therefore, the growth state of emergent plants on the floating bed in heavily polluted water is much better than that in slightly polluted water, resulting in limited purification effect of floating bed plants on slightly polluted water, slow plant growth, exposed floating bed body, and unclear water surface landscape effect.

[0004] An important reason for the excessive water quality in slightly polluted water bodies is endogenous pollution. Most nutrients in water bodies exist in the bottom mud of water bodies. Daily slow material exchange alone cannot normally meet the growth needs of emergent plants in slightly polluted water bodies. The surface layer of the bottom mud in the water body is in a semi-fluid state, and only a slight disturbance can make it diffuse into the water.

[0005] Therefore, if the floating bed is modified so that it can utilize the nutrients in the bottom mud of the water body to grow, it will not only reduce the total pollution load of the water body, but also form a beautiful water surface landscape, achieving the goal of clear water and beautiful scenery.

[0006] The utility model patent with publication number CN218880717U provides an ecological restoration floating bed for purifying river silt. The ecological floating bed includes: a planting basket mounting plate, a guide plate and a buoyancy plate. The guide plate is tilted around the planting basket mounting plate, and the buoyancy plate is arranged under the planting basket mounting plate. The planting basket mounting plate and the guide plate constitute a plant and biofilm comprehensive absorption and disposal treatment area with stable water flow. The floating bed support rod is fixed on the riverbed, and an adjustment nut is arranged on the floating bed support rod. A biofilm carrier is hung at the bottom of the aquatic plant planting basket. However, the floating bed has a complex structure and is not suitable for micro-polluted water environments.

[0007] In view of this, it is necessary to design an improved movable floating bed device that can reduce bottom mud pollution to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a movable floating bed device that can reduce bottom sediment pollution. While solving the problem of poor growth of emergent plants on the floating bed in slightly polluted water bodies, it can simultaneously degrade bottom sediment pollution in the water body, thereby achieving the needs of purifying water quality and beautifying the environment.

[0009] In order to achieve the above-mentioned purpose of the utility model, the utility model provides a movable floating bed device capable of reducing bottom mud pollution, which comprises a floating bed, a watertight enclosure, and a stirring device;

[0010] The impermeable enclosure encloses the bottom area of ​​the floating bed into a closed area, preventing the exchange of water inside and outside the floating bed device during operation;

[0011] The stirring device is a long-axis mixer, which is arranged at the geometric center of the floating bed and connected to the floating bed at the top. When the stirring device is started, the silt at the bottom of the water body is disturbed, so that the water in the impermeable enclosure forms a turbid suspension full of polluted organic matter.

[0012] As a further improvement of the utility model, the watertight enclosure includes a floating foam shaft, an enclosure cloth and a bottom lead sinker;

[0013] The floating foam shaft is arranged around the outer edge of the floating bed, and the two ends of the surrounding spacer cloth are respectively connected to the floating foam shaft and the bottom lead sinker.

[0014] As a further improvement of the utility model, the floating bed is assembled from a plurality of groups of floating plates and planting pots; the planting pots are embedded in the floating plates.

[0017] As a further improvement of the utility model, the fixed anchor block includes a cement block and a nylon rope; two ends of the nylon rope are respectively connected to the floating bed and the cement block.

[0018] As a further improvement of the present invention, the floating bed device is presented in a modular form, and a single group of floating beds is one of rectangular, circular, and regular geometric shapes.

[0019] As a further improvement of the utility model, the stirring device also includes a solar power supply mechanism arranged on the top of the stirring device.

[0020] As a further improvement of the present invention, the fixed anchor block is arranged outside the closed area surrounded by the watertight enclosure.

[0022] The beneficial effects of the utility model are:

[0023] 1. The movable floating bed device provided by the utility model can reduce bottom sediment pollution.

[0030] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0031] See also Figure 1 As shown, the utility model provides a movable floating bed device that can reduce bottom sediment pollution. While solving the problem of poor growth of emergent plants on the floating bed in slightly polluted water bodies, it can simultaneously degrade bottom sediment pollution in the water body, thereby achieving the needs of purifying water quality and beautifying the environment.

[0032] The floating bed device is presented in a modular form, and a single floating bed is preferably rectangular, circular or other relatively regular geometric shapes. It mainly includes a floating bed 1, an impermeable enclosure 2, a stirring device 3, and a fixed anchor block 4.

[0033] The floating bed 1 is assembled from a floating plate 11 and a planting pot 12 , in which emergent plants 13 are planted, and a biofilm carrier 14 is suspended below the connection point of the floating plate 11 .

[0034] The planting pots 12 are embedded in the floating plates 11 ; adjacent floating plates 11 are fixed by connecting buckles or cable ties.

[0035] The watertight enclosure 2 is composed of a floating foam shaft 23, a PVC enclosure cloth 21 and a bottom lead sinker 22. The floating foam shaft 23 is arranged around the outer edge of the floating bed 1, and the two ends of the enclosure cloth 21 are connected to the floating foam shaft 23 and the bottom lead sinker 22 respectively.

[0036] The buoyant foam shaft 23 floats on the water surface and is connected to the outer edge of the floating plate 11. The bottom area of ​​the floating bed 1 is surrounded by a watertight enclosure 2 to form a relatively closed area, and during the operation of the floating bed device, the internal water body is prevented from exchanging with the external water body.

[0037] The stirring device 3 is a long-axis mixer, which is arranged at the geometric center of the floating bed 1. The top is connected to the floating bed, and the stirring device is started to disturb the silt at the bottom of the water body, so that the water in the impermeable enclosure forms a turbid suspension full of polluted organic matter.

[0038] In some embodiments, a solar power supply mechanism is also provided on the top of the stirring device 3. Solar power supply is adopted to facilitate the use of the stirring device 3.

[0039] The fixed anchor block 4 is composed of a cement block 41 and a nylon rope 42. During the operation of the floating bed device, the position of the floating bed 1 can be relatively fixed. The fixed anchor block is arranged outside the closed area formed by the watertight enclosure.

[0040] The working principle of the movable floating bed device that can reduce bottom mud pollution provided by the utility model is:

[0041] When the floating bed device is in operation, the stirring device 3 is turned on to disturb the silt at the bottom of the water body, so that the water in the impermeable enclosure 2 forms a relatively turbid suspension full of polluted organic matter, and some nutrients can be adsorbed on the biofilm carrier 14 and degraded by the microorganisms on the biofilm carrier 14. At the same time, the organic matter in the water body can be absorbed by the emergent plants, and some roots can absorb nutrients from the biofilm carrier 14, which will greatly improve the exchange of nutrients at the bottom of the water body, reduce the pollution of the bottom mud of the water body, and make the floating bed plants in the slightly polluted water body grow normally, forming a landscape effect of clear water bottom and beautiful water surface.

[0042] When the sediment pollutants in one area are reduced to normal values, the fixed anchor block 4 is moved to the next area, and the above steps are repeated until the sediment pollutants in the entire water area are reduced. If the water area is too large, multiple groups of modules can be used at the same time.

[0043] Therefore, the floating bed device can solve the problem of poor growth of floating bed emergent plants in slightly polluted water bodies, while enabling them to grow by utilizing nutrients in the bottom mud of the water body. It can not only reduce the total pollution load of the water body, but also simultaneously degrade the bottom mud pollution of the water body, thereby achieving the needs of purifying water quality and beautifying the environment.

[0044] In summary, the utility model provides a movable floating bed device that can reduce sediment pollution, which includes a floating bed, a watertight enclosure, a stirring device and a fixed anchor block; the watertight enclosure encloses the bottom area of ​​the floating bed into a closed area, and during the operation of the floating bed device, the water inside the floating bed is prevented from exchanging with the external water body; the stirring device is a long-axis mixer, which is arranged at the geometric center of the floating bed, and the top is connected to the floating bed. When the stirring device is started, the silt at the bottom of the water body is disturbed, so that the water body in the watertight enclosure forms a turbid suspension full of polluted organic matter. While solving the problem of poor growth of emergent plants on the floating bed in slightly polluted water bodies, the floating bed device can simultaneously degrade sediment pollution in the water body, thereby achieving the needs of purifying water quality and beautifying the environment.
