Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an ecological floating bed. Background Art

[0002] With economic development, the amount of pollutants discharged in life and production has also increased exponentially. Due to the large-scale discharge of pollutants and unreasonable land use methods, rivers, wetlands, lakes and other water bodies have been seriously polluted and ecologically damaged, and the ecological functions of rivers, wetlands and lakes have been lost or cannot be normally performed. At the same time, the deterioration of water quality in rivers, wetlands and lakes has had many harmful effects on the aquatic ecosystems of water supply sources, threatening the drinking water safety of the region. Among the discharged pollutants, the rich ammonia nitrogen, phosphorus and organic matter will promote the large-scale reproduction of one or several types of plankton in the water body, and the large-scale reproduction of plankton will further consume the dissolved oxygen in the water, making it difficult for other plankton to survive and the imbalance of the food chain in the water body; at the same time, the ammonia nitrogen, phosphorus and organic matter content of the dead cells in the water body after the large-scale reproduction of plankton will further increase, causing the water body to stink and the water quality to further deteriorate, forming a vicious circle.

[0003] Ecological floating bed is an engineering technology used for water purification and ecological restoration. It generally includes a floating bed platform, plants, and microbial communities. The floating bed platform as the foundation needs to have sufficient buoyancy to support the plants and possible additional weight. Suitable types of plants can be selected and planted on the floating bed platform. At the same time, the microbial community formed around the plant roots further decomposes organic pollutants in the water through its metabolic activities. In this way, the joint action of plants and microbial communities is used to absorb and decompose pollutants in the water.

[0004] Conventional ecological floating beds are in a relatively fixed position for a long time, and the water in which they are located may be relatively stagnant or have poor fluidity, resulting in a limited radiation area for purification by the ecological floating beds and unsatisfactory water purification effects. Summary of the invention

[0005] In order to improve the situation where the exchange between water bodies near the location of the ecological floating bed is not sufficient, resulting in unsatisfactory sewage purification effect, the present application provides an ecological floating bed.

[0006] The present application provides an ecological floating bed, which adopts the following technical solution:

[0007] An ecological floating bed, comprising

[0008] A floating plate, wherein the top surface of the floating plate is coaxially rotatably connected with a fixed plate, the outer diameter of the fixed plate is smaller than the outer diameter of the floating plate, a supporting rod is coaxially arranged at the bottom of the fixed plate, the supporting rod vertically passes through the floating plate and extends downward, and a main counterweight is arranged at the bottom of the supporting rod;

[0009] A plurality of planting tubes, the plurality of planting tubes are evenly spaced and arranged circumferentially at the bottom of the floating plate near the outer ring, the planting tubes are placed vertically, the side walls of the planting tubes are hollow mesh-shaped, the floating plate is vertically penetrated with planting holes, the planting holes correspond to the planting tubes one by one, and the planting tubes are used to plant aquatic plants;

[0010] Sailing boards are arranged at the edge of the top surface of the floating disk. There are at least two sailing boards which are symmetrically distributed relative to the center of the floating disk axis. The sailing boards are arranged radially along the floating disk.

[0011] By adopting the above technical scheme, the sailboard is set at the edge of the top surface of the floating plate, the sailboard is symmetrical with respect to the center of the axis of the floating plate and is distributed radially along the floating plate, and the floating plate is rotatably connected to the fixed plate. When there is wind in the waters where the ecological floating bed is placed, the wind blows the sailboard to drive the floating plate to rotate relative to the fixed plate, and the floating plate drives the planting tube at the bottom to rotate synchronously. Aquatic plants are planted in the planting tube. The aquatic plants can absorb nutrients in the water to purify the water body. The aquatic plants rotate with the planting tube, so that the water body with less fluidity around the ecological floating bed is stirred, which improves the fluidity of the water body, so that the water body around the ecological floating bed is fully exchanged and flowed, and the nutrients in the water are more evenly distributed. The aquatic plants can better absorb the nutrients, thereby effectively improving the purification effect of the ecological floating bed on sewage, and the fluidity of the water body around the ecological floating bed is enhanced, which effectively expands the radiation area of ​​the ecological floating bed purification; the main counterweight block at the bottom of the fixed plate is heavy, and after sinking into the water, it can pull the floating plate, so that the ecological floating bed is more stably confined to the water surface and is never blown over by the wind.

[0012] Optionally, an auxiliary counterweight block is provided at the bottom of the support rod, and at least two auxiliary counterweight blocks are provided and are symmetrically distributed relative to the axis of the support rod. The auxiliary counterweight block is connected to the support rod through an elastic member.

[0013] By adopting the above technical solution, in addition to the auxiliary counterweight block, an auxiliary counterweight block is also provided at the bottom of the support rod, which can further increase the overall weight of the ecological floating bed. At the same time, the auxiliary counterweight block is connected to the support rod through an elastic part. When the water at the bottom of the floating plate fluctuates, the elastic part can compress or stretch itself as a buffer, thereby reducing the impact of water fluctuations on the overall ecological floating bed and further improving the stability of the ecological floating bed.

[0014] Optionally, a rotating sleeve is coaxially provided on one end of the support rod near the bottom, and the rotating sleeve is rotatably connected to the support rod. The rotating sleeve is fixed to the side wall of the planting tube by a connecting rod, one end of the elastic member is connected to the outer wall of the rotating sleeve, and the other end is connected to the auxiliary counterweight block. When the rotating sleeve rotates with the planting tube, the auxiliary counterweight block rotates with it and stretches the elastic member.

[0015] By adopting the above technical solution, the elastic part is fixed to the rotating sleeve, and the rotating sleeve is fixed to the planting tube. After the planting tube rotates, it can drive the rotating sleeve to rotate. The rotating sleeve drives the auxiliary counterweight block to rotate through the elastic part. The centrifugal force generated by the rotation of the auxiliary counterweight block stretches the elastic part, and the generated centrifugal force is transmitted to the supporting rod through the elastic part, and finally the centrifugal force is transmitted to the entire ecological floating bed, thereby pulling the entire ecological floating bed downward. When the floating plate is rotated by wind, the centrifugal force generated by the auxiliary counterweight block due to its own rotation can provide additional pulling force for the ecological floating bed, thereby further stabilizing the floating plate.

[0016] Optionally, a protective tube is coaxially sleeved outside the planting tube, a gap is left between the protective tube and the planting tube, the side wall of the protective tube is a hollow mesh, and the aperture of the hollow mesh of the protective tube is larger than the aperture of the hollow mesh of the planting tube.

[0017] By adopting the above technical solution, a hollow protective tube is provided on the outer coaxial sleeve of the planting tube, and the aperture of the hollow mesh on the side wall of the protective tube is larger than the aperture of the hollow mesh of the planting tube, so that the protective tube can block larger debris in the water from entering the planting tube, avoiding affecting the root system of aquatic plants.

[0018] Optionally, a microorganism-carrying rod is provided in the gap between the protective tube and the planting tube. The microorganism-carrying rod is spirally wound outside the planting tube and spirally extends downward along the axis of the planting tube. The microorganism-carrying rod is used for microorganisms to attach and grow.

[0019] By adopting the above technical scheme, the microbial carrier rod can be used for the attachment and growth of microorganisms. After the growth of the microorganisms, the organic matter in the sewage can be decomposed and the water body can be de-nutrified. At the same time, the microorganisms surround the root system of aquatic plants along the rod body, so that the metabolic products of the microorganisms can also be used as growth nutrients for floating plants, promoting the growth of floating plants and forming a good ecological cycle. In addition, the microbial carrier rod extends spirally downward along the axis of the planting tube, which can increase the contact area between the rod body and the sewage and provide more growth space for the microorganisms.

[0020] Optionally, the microorganism-carrying rod has multiple drive plates spaced apart along its spiral direction, and the multiple drive plates are vertically placed and symmetrically distributed along the axis of the planting tube. In the vertical direction, the cross-sectional area of ​​the drive plates is larger than the cross-sectional area of ​​the microorganism-carrying rod, and the microorganism-carrying rod can rotate between the protective tube and the planting tube along the axis of the planting tube.

[0021] By adopting the above technical solution, in the vertical direction, the cross-sectional area of ​​the driving plate is larger than the cross-sectional area of ​​the microorganism-carrying rod. When the planting tube rotates following the floating plate, the driving plate is impacted by the water flow and begins to drive the spiral microorganism-carrying rod to rotate in the gap between the planting tube and the protective tube. The rotating microorganism-carrying rod can further stir the water body and promote the flow of water around the ecological floating bed. At the same time, the rotating microorganism-carrying rod can make the microorganisms on it fully contact with the water body, thereby further improving the decomposition effect of organic matter in the water.

[0022] Optionally, a drainage tube is coaxially arranged at the bottom of the planting tube, the drainage tube is connected to the planting tube, a spiral blade is coaxially arranged inside the drainage tube, and the central rotating shaft of the spiral blade is coaxially fixed to the bottom of the microorganism supporting rod.

[0023] By adopting the above technical solution, a spiral blade is rotatably connected inside the drainage tube, and the spiral blade is coaxially fixed with the microorganism carrying rod, so that the spiral blade can rotate along with the microorganism carrying rod. After the spiral blade rotates, the water under the drainage tube can be transported to the planting tube, or the water in the planting tube can be led out of the drainage tube, thereby promoting the exchange of water inside and outside the planting tube and improving the fluidity of water inside and outside the planting tube.

[0024] Optionally, an aeration pipe is vertically inserted into the planting pipe, and the aeration pipe is used to connect to an external air supply device to supply oxygen to the microorganisms and aquatic plants.

[0025] By adopting the above technical solution, the aeration pipe is inserted into the planting pipe and can be connected to an external air supply device. External oxygen-rich air is introduced into the planting pipe through the aeration pipe. The oxygen introduced by the aeration pipe can increase the activity of microorganisms, thereby promoting the effect of microorganisms decomposing organic matter.

[0026] Optionally, the interior of the floating plate is filled with a lightweight porous filler, and the lightweight porous filler is made of polystyrene foam or perlite.

[0027] By adopting the above technical solution, the interior of the floating plate is filled with lightweight porous fillers such as polystyrene foam or perlite. The filling of these lightweight porous fillers can improve the buoyancy and stability of the floating plate. At the same time, microorganisms can also grow at the bottom of the floating plate. The porous structure is conducive to the attachment and growth of microorganisms.

[0028] Optionally, the top position in the planting tube is filled with a ceramsite matrix, and the ceramsite matrix is ​​used for aquatic plants to attach and grow.

[0029] By adopting the above technical solution, the expanded clay matrix can fix aquatic plants while also having the characteristics of good adsorption performance and strong pollution interception ability. In addition, the expanded clay matrix is ​​a porous material, which is conducive to the growth and reproduction of microorganisms.

[0030] In summary, the present application includes at least one of the following beneficial effects:

[0031] 1. By setting a sailboard on the edge of the floating plate and a planting tube on the bottom of the floating plate, the wind can blow the sailboard to drive the floating plate and the planting tube to rotate. The rotating planting tube can stir the surrounding water, improve the fluidity of the water around the ecological floating bed, and enable aquatic plants to better purify sewage;

[0032] 2. A rotating sleeve is arranged on the support rod, and a plurality of auxiliary counterweight blocks connected by elastic members are symmetrically arranged at the bottom of the rotating sleeve. The auxiliary counterweight blocks will generate centrifugal force when rotating with the rotating sleeve. The generated centrifugal force is transmitted to the entire ecological floating bed through the elastic member, thereby applying an additional downward pulling force to the ecological floating bed to improve the stability of the ecological floating bed;

[0033] 3. By setting a driving plate on the microorganism-carrying rod, the water flow impacting the driving plate can drive the microorganism-carrying rod to rotate along its own axis, so that the microorganisms on the rod can be more fully in contact with the water body, thereby further improving the effect of microbial decomposition.

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] The present application embodiment discloses an ecological floating bed, referring to Figure 1 and Figure 2 The ecological floating bed includes a floating plate 1 and a fixed plate 2. The floating plate 1 is in the shape of a flat cylinder as a whole. The fixed plate 2 is coaxially arranged on the top surface of the floating plate 1. The fixed plate 2 is rotatably connected to the floating plate 1 and the outer diameter of the fixed plate 2 is smaller than the outer diameter of the floating plate 1. The interior of the fixed plate 2 can be solid, and the interior of the floating plate 1 can be filled with a lightweight porous filler. The lightweight porous filler can be made of materials such as polystyrene foam or perlite. The filled lightweight porous filler can improve the buoyancy and stability of the floating plate 1, so that the entire ecological floating bed can withstand a certain weight. The entire ecological floating bed uses the floating plate 1 as the main carrier to ensure that the ecological floating bed can float stably on the water surface. In other embodiments of the present application, the diameter of the floating plate 1 can be extended or shortened according to actual conditions to change the contact area between the floating plate 1 and the water surface, so that the floating plate 1 can serve as a stable carrier of the ecological floating bed. At the same time, the floating plate 1 itself can also be hollow, and a microbial community is established at the bottom of the floating plate 1. The porous structure of the lightweight porous filler is conducive to the attachment and growth of microorganisms, so that the purification capacity of the ecological floating bed is improved.

[0041] A support rod 3 is coaxially fixed to the bottom of the fixed plate 2. The support rod 3 passes vertically downward through the floating plate 1 and continues to extend downward. The bottom of the support rod 3 is detachably connected to a main counterweight block 31, and the detachable connection method can be bolt connection or clamping. The main counterweight block 31 is spherical as a whole. The main counterweight block 31 is solid inside and can be made of iron material. The main counterweight block 31 has a large mass. After sinking into the water, it can pull the floating plate 1, and the ecological floating bed can be more stably restricted to the water surface so that it will not be blown over by the wind. In addition, an anchor rope can be fixed on the main counterweight block 31, and the other end of the anchor rope is anchored in the soil foundation at the bottom of the water to further improve the stability of the ecological floating bed.

[0042] Reference Figure 1 and Figure 2 Four planting tubes 4 are fixedly connected to the bottom of the floating plate 1 near the outer ring along the circumferential direction. The planting tubes 4 are vertical and evenly spaced, and the side walls of the planting tubes 4 are hollow mesh structures. The floating plate 1 is vertically penetrated with planting holes 11 at the positions corresponding to the planting tubes 4. The planting tubes 4 are inserted and fixed in the planting holes 11. The top position of the planting tubes 4 is filled with ceramsite matrix 41. Aquatic plants of suitable types are selected and inserted and planted in the planting tubes 4. The ceramsite matrix 41 can fix aquatic plants while also having the characteristics of good adsorption performance and strong pollution interception ability. In addition, the ceramsite matrix 41 is a porous material, which is conducive to the growth and reproduction of microorganisms, and can further improve the purification capacity of the ecological floating bed.

[0043] A plurality of sailboards 12 are fixed to the edge of the top surface of the floating disk 1. The sailboards 12 are fixed to the floating disk 1 through vertical rods. The number of the sailboards 12 is at least two, and the sailboards 12 are centrally symmetrically distributed relative to the axis of the floating disk 1. In the embodiment of the present application, the number of the sailboards 12 is three, and the sailboards 12 are all placed vertically, and the length direction of the horizontal projection of the sailboards 12 is arranged along the radial direction of the floating disk 1. The sailboard 12 is fixed to the floating plate 1 through a vertical rod. When there is wind in the waters where the ecological floating bed is placed, the wind blows the sailboard 12, thereby driving the floating plate 1 to rotate relative to the fixed plate 2. The floating plate 1 drives the planting tube 4 at the bottom to rotate synchronously. The rotating planting tube 4 stirs up the water body with originally low fluidity around the ecological floating bed, thereby improving the fluidity of the water body, allowing the water body around the ecological floating bed to fully exchange and flow, and the distribution of nutrients in the water is more even; at the same time, the aquatic plants rotate with the planting tube 4, so that the aquatic plants can better absorb the nutrients in the water body, thereby effectively improving the purification effect of the ecological floating bed on sewage, and the fluidity of the water body around the ecological floating bed is enhanced, which effectively expands the radiation area of ​​the purification effect of the ecological floating bed.

[0044] Reference Figure 1 and Figure 3 , an auxiliary counterweight 32 is provided at the bottom of the support rod 3. The auxiliary counterweight 32 can also be a solid iron spherical object. The volume and mass of the auxiliary counterweight 32 are smaller than the main counterweight 31. At least two auxiliary counterweights 32 are provided and are symmetrically distributed relative to the axis of the support rod 3. In the embodiment of the present application, the number of the auxiliary counterweights 32 is two, and the auxiliary counterweights 32 are connected to the support rod 3 through an elastic member 34, which can be a tension spring. A rotating sleeve 35 is coaxially sleeved at one end of the support rod 3 near the bottom. The rotating sleeve 35 is rotatably connected to the support rod 3. The rotating sleeve 35 is fixed to the side wall of the planting tube 4 through a connecting rod 33. Two connecting rods 33 can be provided so that the position of the rotating sleeve 35 is fixed relative to the support rod 3. One end of the elastic member 34 is fixedly connected to the outer wall of the rotating sleeve 35, and the other end is fixedly connected to the auxiliary counterweight 32.

[0045] The auxiliary counterweight 32 can further increase the overall weight of the ecological floating bed. When the water at the bottom of the floating plate 1 fluctuates, the water drives the auxiliary counterweight 32 to move, and the elastic member 34 can compress or stretch itself as a buffer, reducing the impact of the ecological floating bed as a whole on the water body fluctuations, and enhancing the stability of the ecological floating bed. If the planting tube 4 rotates, the rotating sleeve 35 can be driven to rotate by the connecting rod 33, and the rotating sleeve 35 drives the auxiliary counterweight 32 to rotate through the elastic member 34. The centrifugal force generated by the rotation of the auxiliary counterweight 32 stretches the elastic member 34, and the centrifugal force generated is transmitted to the support rod 3 through the elastic member 34, and finally the centrifugal force is transmitted to the entire ecological floating bed, thereby pulling the entire ecological floating bed down. When the floating plate 1 is rotated by wind and drives the planting tube 4 to rotate, the centrifugal force generated by the auxiliary counterweight 32 due to its own rotation can provide additional pulling force for the ecological floating bed, thereby further stabilizing the floating plate 1. In other embodiments of the present application, the number of auxiliary counterweights 32 can be increased according to actual conditions, so that the ecological floating bed can work more stably.

[0046] Reference Figure 3 An aeration pipe 8 is vertically inserted in each planting tube 4, and a plurality of through holes are provided in the vertical direction. A rotary joint 21 is coaxially arranged on the fixed disk 2, and the rotary joint 21 includes a fixed portion 211 and a rotating portion 212, and the rotating portion 212 can rotate relative to the fixed portion 211. The fixed portion 211 of the rotary joint 21 is fixed to the fixed disk 2, and the rotating portion 212 penetrates into the interior of the floating disk 1 and is fixed to the floating disk 1. One end of the top of the aeration pipe 8 extends upward to the interior of the floating disk 1 and is connected to the rotating portion 212. The top of the fixed portion 211 is connected to an air intake pipe 213, and the air intake pipe 213 can be connected to an air supply device such as an air compressor. The external oxygen-rich air is drawn into the aeration pipe 8 through the air intake pipe 213 to supply oxygen to the microorganisms and aquatic plants.

[0047] Reference Figure 3 and Figure 4 A protective tube 5 is coaxially sleeved outside the planting tube 4, and the top of the protective tube 5 is fixed to the bottom surface of the floating plate 1, and a gap is left between the protective tube 5 and the planting tube 4. The side wall of the protective tube 5 is also a hollow mesh structure, and the aperture of the hollow mesh of the protective tube 5 is larger than the aperture of the hollow mesh of the planting tube 4, so that the protective tube 5 can prevent large debris in the water from entering the planting tube 4, avoiding affecting the root system of aquatic plants.

[0048] A microorganism-carrying rod 6 is arranged in the gap between the protective tube 5 and the planting tube 4. The microorganism-carrying rod 6 is used for microorganisms to attach and grow, and the microorganism-carrying rod 6 can rotate between the protective tube 5 and the planting tube 4 along the axis of the planting tube 4. The microorganism-carrying rod 6 itself can have a hole-like structure, so that microorganisms can more easily attach thereto. The growth of microorganisms can decompose organic matter in sewage and de-nutrify the water body. At the same time, the microorganisms surround the root system of aquatic plants along the rod body, so that the metabolic products of the microorganisms can also be used as the growth nutrients of floating plants, promote the growth of floating plants, and form a good ecological cycle. At the same time, the microorganism-carrying rod 6 is spirally wound outside the planting tube 4 and spirally extends downward along the axis of the planting tube 4, which can increase the contact area between the rod body and the sewage and provide more growth space for microorganisms.

[0049] Reference Figure 3 and Figure 4 , the microorganism-carrying rod 6 has multiple drive plates 61 spaced apart along its own spiral direction. Looking from top to bottom along the axis of the planting tube 4, the multiple drive plates 61 are all placed vertically and symmetrically distributed along the axis of the planting tube 4, and the cross-sectional area of ​​the drive plates 61 in the vertical direction is larger than the cross-sectional area of ​​the microorganism-carrying rod 6. When the planting tube 4 rotates following the floating plate 1, the drive plate 61 is impacted by the water flow and begins to drive the spiral microorganism-carrying rod 6 to rotate in the gap between the planting tube 4 and the protective tube 5. The rotating microorganism-carrying rod 6 can further stir the water body and promote the flow of the water body around the ecological floating bed. At the same time, the rotating microorganism-carrying rod 6 can make the microorganisms on it fully contact with the water body, thereby further improving the decomposition effect of organic matter in the water. At the same time, the microorganism-carrying rod 6 can disperse the oxygen-rich air introduced into the water body when rotating, so that oxygen can be more fully dissolved in the water body.

[0050] A drainage tube 7 is coaxially fixed to the bottom of the planting tube 4. The side wall of the drainage tube 7 is in a closed state. A through hole is opened through the bottom of the drainage tube 7 for water to flow into the drainage tube 7. The top of the drainage tube 7 is connected to the planting tube 4. A spiral blade 71 is coaxially arranged in the drainage tube 7. A connecting ring coaxial with the drainage tube 7 is fixed at one end of the bottom of the microorganism-carrying rod 6. The central rotating shaft of the spiral blade 71 is coaxially fixed with the connecting ring, so that the rotation of the microorganism-carrying rod 6 can drive the spiral blade 71 to rotate through the connecting ring. After the spiral blade 71 rotates, it can drain the water under the drainage tube 7 into the planting tube 4, or draw the water in the planting tube 4 out of the drainage tube 7, thereby further promoting the exchange of water inside and outside the planting tube 4 and improving the fluidity of water inside and outside the planting tube 4.

[0051] The implementation principle of an ecological floating bed in an embodiment of the present application is as follows: external wind force drives the floating plate 1 to rotate by blowing the sailboard 12, and the floating plate 1 drives the planting tube 4 at the bottom to rotate. The rotating planting tube 4 stirs the water flow around the ecological floating bed to promote water exchange. The rotating planting tube 4 drives the auxiliary counterweight block 32 to rotate through the rotating sleeve 35. The centrifugal force generated by the auxiliary counterweight block 32 due to its own rotation can provide additional pulling force for the ecological floating bed, thereby further stabilizing the floating plate 1. The rotation of the planting tube 4 causes the driving plate 61 to be impacted by the water flow, driving the spiral microorganism carrying rod 6 to rotate. The rotating microorganism carrying rod 6 can further stir the water and promote the flow of water around the ecological floating bed. At the same time, the rotating microorganism carrying rod 6 can make the microorganisms on it fully contact with the water, thereby further improving the decomposition effect of organic matter in the water.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
