Description

Technical Field

[0001] The invention relates to the technical field of water pollution prevention and control equipment, and in particular to a controllable ecological floating bed for water pollution prevention and control. Background Art

[0002] Ecological floating beds are an efficient, economical and eco-friendly water remediation technology that is widely used in the fields of eutrophic water remediation, black and odorous water treatment, and landscape water beautification. They have good application prospects and are usually composed of floating bodies, plants and root-fixing media. They are used to control eutrophication problems in lakes, rivers, ponds and other water bodies. By planting aquatic plants with purification functions on the water surface, the absorption and transformation of plants are used to remove nutrients such as nitrogen and phosphorus from the water, thereby achieving the purpose of purifying water quality and improving water ecology, while increasing the biodiversity of the water body. The biofilm formed by the plant roots can provide attachment space for microorganisms and promote the degradation of pollutants by microorganisms. Microorganisms attached to the roots of aquatic plants in the ecological floating bed can significantly improve the degradation efficiency of pollutants and improve water quality. Microorganisms attached to the plant roots can decompose organic pollutants in the water, reduce COD and BOD in the water, participate in nitrogen and phosphorus cycles, reduce eutrophication of water bodies, and release nutrients needed by plants, promoting plant growth. They also inhibit the reproduction of harmful microorganisms and algae by competing for nutrients.

[0003] The root oxygen secretion (ROL) function of plants can provide oxygen for microorganisms. However, the existing ecological floating beds used in sewage waters, especially in water bodies with poor fluidity such as sewage rivers and lakes, are insufficient to supplement oxygen for microorganisms by relying solely on the oxygen secretion (ROL) function of plant roots themselves. This will lead to adverse consequences such as reduced microbial activity, changes in community structure, and decreased pollutant removal efficiency. At the same time, it will also cause plant root hypoxia and growth stunts, thereby affecting the balance and function of the entire ecosystem, causing water quality deterioration, reduced biodiversity and other problems. Therefore, there are certain defects. Therefore, it is necessary to develop a controllable ecological floating bed for water pollution prevention and control to enhance the oxygen supply of plant roots to microorganisms. Summary of the Invention

[0004] In response to the above-mentioned defects and problems, the present invention provides a controllable ecological floating bed for water pollution prevention and control. Its purpose is to use the alternating lifting mechanism of the floating bed unit, combined with the synergistic effect of plant roots and microorganisms, so that the plant roots can be briefly exposed to the air, thereby enhancing the oxygen secretion function of the plant roots, providing sufficient oxygen for microorganisms to promote their activity, and enhancing the water purification efficiency.

[0005] The solution adopted by the present invention to solve its technical problems is: a controllable ecological floating bed for water pollution prevention and control, including a floating bed unit, a main buoyancy box and a driving mechanism. Several floating bed units constitute the ecological floating bed, and each floating bed unit is arranged alternately in odd and even numbers. The main buoyancy box is arranged in the center of the ecological floating bed, and is connected to the edge float on the surrounding side of the ecological floating bed; the top of the main buoyancy box is connected to the top plate through a column, and a solar cell panel is installed on the top plate; the floating bed unit includes a floating frame, a floating body and a planting net frame, a vertical trough body is provided on the inner side of the floating frame, the floating body is connected to the vertical trough body through an edge protrusion, and an air chamber is provided inside the floating body, and air holes are also provided on the air chamber, the planting net frame is provided on the upper part of the floating body, and adjacent floating bodies can be relatively raised and lowered. Sliding; the driving mechanism includes a motor, a crank shaft, a piston cylinder, a balance pipe and a soft branch pipe. The motor is arranged inside the main buoyancy box, and the output end of the motor is connected to the crank shaft through a gearbox. The piston cylinder is arranged on the left and right sides of the top of the main buoyancy box, and the piston set in the piston cylinder is hinged to the crank shaft through a hinge rod. The balance pipe is vertically arranged in the air chamber, and the top of the balance pipe extends out of the air chamber and is connected to the soft branch pipe. The floats in the odd and even numbered float units are respectively connected to the left and right piston cylinders through the balance pipe and the soft branch pipe; the driving mechanism can respectively inject water or pump water into or out of the float air chambers in the odd and even numbered float units, change the specific gravity of the floats in adjacent odd and even numbered float units, and control the floats in adjacent single and even numbered float units to move alternately up and down.

[0006] The beneficial effects of the present invention are as follows: the present invention has a unique structure and an ingenious design. When water is injected or pumped into the air chamber of the float through the driving mechanism, the specific gravity of the float in the odd and even numbered float unit can be changed, and the floats in the adjacent odd and even numbered floating bed units can be controlled to move up and down alternately, so that the roots of the plants in the planting net frame on the upper part of each float can be temporarily exposed to the air due to the upward movement, and then sink into the water again. By controlling the alternate rise and fall of the float, the roots of the plants can be alternately exposed to the air and water. To provide the required oxygen for microorganisms, plant roots can absorb oxygen from the air through photosynthesis and respiration, and transport oxygen to the root zone through the root aerenchyma. In addition, the root oxygen secretion (ROL) function of plants can also provide oxygen for microorganisms, increasing their biomass and biological activity, and enhancing the ecological floating bed's efficiency in removing organic loads from the water and removing nitrogen and phosphorus. Moreover, through the alternating rising and sinking of the float, plant roots can be briefly exposed to the air, directly obtaining oxygen from the air, improving the oxygen supply to the roots and reducing root rot caused by hypoxia. Moreover, by planting different plants in adjacent floating bed units and achieving repeated flow of water between adjacent units through rising and falling changes, the water purification efficiency can be significantly improved. The water flow between the roots of different plants can achieve complementarity between different plants, and through the synergistic action of multiple microbial populations, water purification can be completed efficiently together. At the same time, the local water flow caused by the high and low switching of different units is conducive to the exchange of water quality between the entire ecological floating bed and the external water, further improving the water purification efficiency of the entire water area.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and examples.

[0019] Example 1: The root oxygen secretion (ROL) function of plants can provide oxygen for microorganisms. However, the existing ecological floating beds used in sewage waters, especially in water bodies with poor fluidity such as sewage rivers and lakes, are insufficient to supplement oxygen for microorganisms by relying solely on the oxygen secretion (ROL) function of the plant roots themselves. This can lead to adverse consequences such as reduced microbial activity, changes in community structure, and decreased pollutant removal efficiency. At the same time, it can also cause plant root hypoxia and growth stunts, thereby affecting the balance and function of the entire ecosystem, causing problems such as deterioration of water quality and reduced biodiversity.

[0020] In response to the above problems, this embodiment provides a controllable ecological floating bed for water pollution prevention and control, including a floating bed unit 3, a main buoyancy box 2 and a driving mechanism 4. The driving mechanism 4 is intended to control the floats 32 of adjacent floating bed units 3 to move up and down alternately, so that the roots of plants can be briefly exposed to the air, thereby enhancing the oxygen secretion function of the roots, providing sufficient oxygen for microorganisms, promoting their activity, and improving the water purification effect. Figure 1-2 As shown, the main body of the ecological floating bed 1 is composed of a number of floating bed units 3, and each floating bed unit 3 is arranged alternately according to odd and even numbers, as shown in FIG. Figure 2 As shown in the top view, when arranging the floating body 32 units, the floating bed units in the bottom row can be single-numbered, and the floating bed units 3 in the upper row can be double-numbered, so that the single-numbered floating bed units 3 and the double-numbered floating bed units are arranged alternately.

[0021] The main buoyancy box 2 is arranged at the center of the ecological floating bed 1, and the edge float 11 is arranged on the periphery of the main body of the ecological floating bed 1, so that the ecological floating bed 1 is a polygonal structure. The ecological floating bed 1 can be connected to the shore through an anchoring rope, or be stabilized in the water by sinking an anchor.

[0022] like Figure 3 As shown, a triangular column 21 is provided on the top of the main buoyancy tank 2, a top plate 22 is installed on the top of the column 21, and a solar cell panel 23 is provided on the upper side of the top plate 22 to provide energy.

[0023] A control unit is also provided in the main buoyancy tank 2, and the control unit includes a controller and a remote communication module.

[0024] like Figure 4-7 As shown, the floating bed unit 3 includes a floating frame 31, a floating body 32 and a planting net frame 33. A vertical groove body 35 is provided on the inner circumference of the floating frame 31. An embedding groove is vertically penetrated through the inner circumference of the floating frame 31. The vertical groove body 35 is fixedly connected in the embedding groove by a lock wire, and the internal top and bottom ends of the vertical groove body 35 are closed, and adjacent floating frames 31 are fixedly connected; an edge protrusion 34 is provided on the circumference of the floating body 32, and the floating body 32 is fitted with the vertical groove body 35 through the convex and concave connection of the edge protrusion 34. Through the mutual cooperation of the edge protrusion 34 and the vertical groove, the floating body 32 can be lifted and slid up and down in the floating frame 31.

[0025] An air chamber 36 is provided inside the float 32 , and the air chamber 36 of the float 32 can be filled with water in advance so that the buoyancy and gravity of the float 32 are in a balanced state.

[0026] like Figure 7 As shown, the planting net frame 33 is arranged on the upper part of the float 32, and the adjacent floats 32 can be controlled by the driving mechanism 4 to rise and fall relative to each other. A groove is provided on the upper part of the float 32, and the planting net frame 33 is evenly arranged in the groove of the float 32, and a mesh is provided at the bottom of the groove. Plants are loaded in the planting net frame 33, and the roots of the plants are provided with a root fixing medium. The root fixing medium is a material used to fix the roots of plants and provide a growth environment for them. It can not only fix the plants, but also provide the roots with necessary water, oxygen and nutrients, and also help the attachment of microorganisms, thereby enhancing the purification effect of the ecological floating bed 1. Common root fixing media include: foam plastic board, sponge, coconut shell fiber, volcanic gravel, expanded clay, polypropylene fiber, etc. Different materials can be used in combination according to specific environmental conditions and purification goals.

[0027] like Figure 4-6As shown, the drive mechanism 4 includes a motor 41, a crankshaft 42, a piston 44, a balance pipe 46 and a flexible branch pipe 47. The motor 41 is arranged inside the main pontoon 2. The output end of the motor 41 is connected to the gearbox 411, and the crankshaft 42 is connected to the output end of the gearbox 411. The motor 41 can drive and control the rotation of the crankshaft 42, and the speed of the crankshaft 42 is relatively slow. A battery 48 is provided in the main pontoon 2. The solar panel 23 collects energy and stores it in the battery 48, so that the battery 48 provides power to the drive mechanism 4. like Figure 3 and Figure 5 As shown, as shown, the piston 44 cylinder is arranged on the left and right sides of the top of the main float box 2, and the bottom of the left piston cylinder 451 and the right piston cylinder 452 are connected to the interior of the main float box 2. The piston 44 is installed inside the piston cylinder 44, and the piston 44 is connected to the crank shaft 42 through a hinged rod 43. The crank shaft 42 rotates to control the pistons 44 in the left piston cylinder 451 and the right piston cylinder 452 to move alternately, and the inner cavities of the left piston cylinder 451 and the right piston cylinder 452 are respectively connected to the main pipe 49.

[0028] The balancing pipe 46 is vertically arranged in the air chamber 36 of the float 32, and the top of the balancing pipe 46 extends out of the air chamber 36 and is connected to the soft branch pipe 47. The air chamber 36 of the float 32 of each single-numbered floating bed unit 3 is connected to the left piston cylinder 451 through the balancing pipe 46, the soft branch pipe 47 and the main pipe 49, wherein each soft branch pipe 47 is connected to the main pipe 49 in a collective manner. The air chamber 36 of the float 32 of each double-numbered floating bed unit 3 is connected to the right piston cylinder 452 through the balancing pipe 46, the soft branch pipe 47 and the main pipe 49, wherein each soft branch pipe 47 is connected to the main pipe 49 in a collective manner.

[0029] like Figure 8-9 As shown, a free piston 463 is provided inside the balance tube 46, and an upper stop 461 and a lower stop 462 are respectively provided on the upper and lower sides of the balance tube 46. The upper stop 461 and the lower stop 462 are used to limit the free piston 463. The free piston 463 divides the interior of the balance tube 46 into an upper cavity and a lower cavity. The lower cavity is connected to the interior of the air chamber 36 of the float 32, and the upper cavity is connected to the inner cavity of the piston 44 cylinder through the soft branch tube 47.

[0030] The driving mechanism 4 can inject or pump water into the air chambers 36 of the floats 32 in the odd and even numbered floats 32 units respectively, change the specific gravity of the floats 32 in adjacent odd and even numbered floats 32 units, and control the floats 32 in adjacent odd and even numbered floating bed units 3 to move alternately up and down.

[0031] When water is injected into or pumped out of the air chamber 36 of the float 32 through the driving mechanism 4, the specific gravity of the float 32 in the odd-numbered and even-numbered float 32 units can be changed, and the floats 32 in adjacent odd-numbered and even-numbered floating bed units 3 can be controlled to move up and down alternately, and alternately at a certain frequency, so that the roots of plants in the planting net frame 33 on the upper part of each float 32 can be briefly exposed to the air due to the upward movement, and then sink into the water again, and this process is repeated; by controlling the alternating rise and fall of the float 32, the roots of the plants can be alternately exposed to the air and water, which can not only enhance the synergistic effect between the plant roots and microorganisms, provide the required oxygen for the microorganisms, and enhance the activity of the microorganisms, but also improve the purification effect on the water body and enhance the adaptability and flexibility of the ecological floating bed.

[0032] In the initial state, the air chamber 36 of the float 32 is filled with water in advance so that the buoyancy and gravity of the float 32 are in a balanced state. In this state, only a small amount of water needs to be injected or extracted to break the balanced state and the critical value of the buoyancy and gravity of the float 32, thereby increasing the buoyancy of the float 32 or increasing the gravity of the float 32, which will cause the float 32 to sink or float to the surface.

[0033] In the initial state, the free piston 463 in the balance tube 46 is in a middle balanced state. When the piston 44 injects water into the upper chamber of the balance tube 46, the free piston 463 moves downward, sending the water pressure in the lower chamber of the balance tube 46 to the air chamber 36 of the float 32. At this time, the water level in the air chamber 36 of the float 32 increases, and the volume of the upper chamber of the balance tube 46 increases. The additional water enters the upper chamber of the balance tube 46, increasing the gravity of the float 32, causing the float 32 to sink into the water. When the piston 44 pumps water into the balance pipe 46, the free piston 463 moves upward, pumping the water in the air chamber 36 of the float 32 to the lower cavity inside the balance pipe 46. At this time, the water level in the air chamber 36 of the float 32 decreases, and at the same time, the volume of the upper cavity inside the balance pipe 46 becomes smaller. The water in the upper cavity inside the balance pipe 46 flows back to the piston 44, reducing the gravity of the float 32, and the float 32 will float to the surface.

[0034] The water injected or pumped out is only the water in the upper chamber inside the balance pipe 46 , and the capacity of the piston 44 cylinder is sufficient to realize the pumping or filling operation of each float 32 .

[0035] The existing plant root oxygen secretion can provide a certain amount of oxygen for microorganisms, but in highly polluted water bodies, such as sewage rivers, lakes and other water bodies with poor water flow, the microorganisms have a large oxygen demand, and relying solely on root oxygen secretion may not be enough to meet the demand. Therefore, in this embodiment, when the float 32 floats up, the plant roots are briefly exposed to the air, which can provide the required oxygen for the microorganisms. Through photosynthesis and respiration, the plant roots can absorb oxygen in the air and transport oxygen to the root zone through the aerenchyma of the root system. In addition, the plant root oxygen secretion (ROL) function can also provide oxygen for microorganisms, increase the biomass and biological activity of microorganisms, and enhance the removal efficiency of the organic load in the water and the nitrogen and phosphorus removal effect of the ecological floating bed.

[0036] That is to say, when the roots of plants are exposed to the air, they can obtain oxygen directly from the air and transport it to the root zone through the aerenchyma of the root system, providing sufficient oxygen for microorganisms. The oxygen secretion function of the plant roots forms an oxidized area in the root zone, which is conducive to the growth and reproduction of aerobic microorganisms. At the same time, through the synergistic effect of the plant roots and microorganisms, it can effectively remove nitrogen, phosphorus and other pollution in the water body, enhance the activity of microorganisms, accelerate the decomposition of organic matter in the water body, reduce COD, BOD and other indicators of the water body, and improve water quality.

[0037] When the plant roots re-enter the water, the root oxygen secretion function continues to provide oxygen to the microorganisms, maintaining their growth and metabolic activities.

[0038] When plant roots are deficient in oxygen, they are susceptible to infection by pathogens, leading to root rot. In this embodiment, by alternately floating up and down the float 32, the plant roots can be briefly exposed to the air and obtain oxygen directly from the air, thereby improving the oxygen supply to the roots and reducing root rot caused by lack of oxygen.

[0039] Moreover, by planting different plants in adjacent floating bed units 3 and realizing repeated flow of water between adjacent floating bed units 3 through the rising and falling changes of the float 32, the water purification efficiency can be significantly improved. The water flow between the roots of different plants can realize the complementarity between different plants, and through the synergistic effect of multiple microbial populations, water purification can be completed efficiently together. At the same time, the local water flow caused by the high and low switching of different units is beneficial to the water quality exchange between the entire ecological floating bed 1 and the external water area, further improving the water purification efficiency of the entire water area.

[0040] Different plant roots harbor distinct microbial populations, each with distinct specialties in breaking down impurities in water. For example, canna has a strong absorption capacity for nitrogen and phosphorus, while calamus has a stronger absorption capacity for heavy metals. By connecting the microbial populations of different plant roots through water flow, multiple microorganisms can participate in water purification, thereby improving purification efficiency. Furthermore, because different plants have different mechanisms for removing pollutants, the exchange of water flow allows for synergistic removal of pollutants by multiple plants. For example, a combination of canna and calamus can simultaneously remove nitrogen, phosphorus, and heavy metals from water. This synergistic effect can significantly enhance water purification effectiveness.

[0041] In this embodiment, the rise and fall of different floats 32 can cause local water flow. This local water flow can increase the fluidity of the water body and promote the exchange of substances between the water body and the surrounding water area. This fluidity helps to exchange the purified water with the surrounding water area, thereby improving the water purification efficiency of the entire water area. The local water flow increases the contact area between the water body and the air, promoting the dissolution and exchange of oxygen. This helps to increase the dissolved oxygen content of the water body, which is beneficial to the growth and activity of microorganisms.

[0042] Preferably, considering that when the plant grows heavier and the weight of the float 32 increases, the free piston 463 is pumped upward, the water in the upper cavity of the balance pipe 46 is pumped out, and at the same time the water in the air chamber 36 of the float 32 is pumped to the lower cavity of the balance pipe 46. At this time, the float 32 may be unable to float due to the increase in weight, so a drainage component is also provided. Figure 10 As shown, the drainage assembly includes an auxiliary plate 51 and an auxiliary pipe 52. The auxiliary pipe 52 is sleeved within the auxiliary plate 51. The auxiliary plate 51 is fixedly connected to the balancing pipe 46. The input end of the auxiliary pipe 52 communicates with the lower cavity inside the balancing pipe 46. Through holes are correspondingly formed in the side wall of the floating frame 31 and the edge protrusion 34. The output end of the auxiliary pipe 52 is fixed in the through hole in the side wall of the floating frame 31. A one-way valve 53 is installed at the output end of the auxiliary pipe 52. At the same time, a drainage hole 54 is formed on the lower side of the inner end surface of the vertical trough body 35. When the float 32 is unable to float due to the increase in weight, the output end of the auxiliary pipe 52 corresponds to the drain hole 54 of the vertical trough body 35. At this time, when the piston 44 injects water into the upper cavity inside the balance pipe 46, the free piston 463 moves downward to send the water pressure in the lower cavity inside the balance pipe 46 to the air chamber 36 of the float 32. At the same time, the water in the lower cavity of the balance pipe 46 will also be pressed out of the float 32 through the auxiliary pipe 52 and the one-way valve 53, reducing the weight of the float 32. The above process is repeated until the buoyancy and gravity of the float 32 are in a balanced state; when the weight of the float 32 decreases and floats upward, the output end of the auxiliary pipe 52 will be misaligned with the drain hole 54. At this time, the output end of the auxiliary pipe 52 is blocked by the inner end face of the vertical trough body 35.

[0043] Example 2: A controllable ecological floating bed for water pollution prevention and control in this embodiment is described centering on the differences from Example 1.

[0044] In this embodiment, an air hole is opened in the air chamber 36 , and an air pipe 361 is connected to the air hole. The air pipe 361 has a side opening to prevent debris from entering the air chamber 36 of the float 32 .

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the scope of protection of the present invention.
