Description

Technical Field

[0001] The present invention relates to the technical field of water body restoration, and specifically to an aquatic plant and animal composite floating bed. Background Art

[0002] At present, many rivers and lakes in China are polluted to varying degrees. To address the problems of water quality deterioration and water ecological damage, ecological floating beds are widely used to purify water quality in polluted waters. An ecological floating bed is a technology that uses soilless cultivation techniques, with polymer materials as the matrix and carrier, and realizes water body restoration through processes such as plant root absorption, microbial degradation, and secretion reactions.

[0003] The invention patent with the application number 2018111062917 discloses a composite ecological floating bed, which is arranged on the water body to be restored, including a floating bed frame and a floating bed body. The floating bed body includes a floating bed planting layer floating on the water surface, and the floating bed body also includes a microbial frame layer located under the water surface and parallel to the floating bed planting layer. The floating bed planting layer and the microbial frame layer are connected as a whole through the floating bed frame. However, when the wind is strong, it will damage the floating bed frame, the floating bed body, and the plants on the planting layer, thereby affecting the normal growth of the plants and resulting in the loss of the water purification effect on the water body.

[0004] The invention patent with the application number 2015104039024 discloses a composite ecological floating bed, including a floating bed cavity, a planting groove, floating bed plants, planting ceramsite, a net basket, suspended fillers, an electric propeller, a cable, and a fixed anchor. During operation, the electric propeller generates an upward water flow. The water flow enters the net basket from the central area at the bottom of the net basket and then flows out from the periphery of the net basket. The pollutants in the water are absorbed and removed by the suspended fillers and plant roots in the net basket, achieving the effect of water quality purification. However, when the wind is strong, the water flow will generate large water waves, which easily cause damage to the overall structure, thereby affecting the service life.

[0005] Moreover, the content of dissolved oxygen in the water body changes with the weather. When the oxygen content in the water body is low, it will affect the growth and survival of aquatic plants and animals, and even cause the death of aquatic plants and animals. In addition, during long-term use, a large amount of floating substances in the water will accumulate at the bottom of aquatic plants and around aquatic animals, which will also seriously affect the growth and survival of aquatic plants and animals and is not convenient for cleaning.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] First embodiment

[0035] Please refer to Figure 1-2 Figs. and 4, this embodiment provides a technical solution: an aquatic plant and animal composite floating bed, including a plant tray 1, a fixed frame 102 is arranged outside the plant tray 1. Specifically, the fixed frame 102 is used to reinforce the plant tray 1. Support rods 103 are evenly arranged on the bottom surface of the fixed frame 102, and an animal breeding cage 104 is arranged at the bottom end of the support rod 103. The plant tray 1 is composed of a plurality of square trays that are movably connected to each other. A plant cultivation barrel 101 is embedded in the middle of each square tray. Through grooves are evenly formed on the circumferential side surface of the bottom of the plant cultivation barrel 101. The animal breeding cage 104 and the plant cultivation barrel 101 are arranged in a staggered manner. Ryegrass is planted in the plant cultivation barrel 101, and ventilation grooves are evenly formed on both sides of the animal breeding cage 104. Snails are cultured in the animal breeding cage 104.

[0036] At the bottom of the fixed frame 102, there is a floating body assembly 2. The floating body assembly 2 includes a floating box 204 provided at the bottom of the fixed frame 102. On both sides of the floating box 204, there are symmetrically arranged brackets 201. The brackets 201 are in an L-shaped structure. The bottom ends of the brackets 201 on both sides are fixedly connected to both sides of the floating box 204 respectively. The top ends of the brackets 201 are fixedly connected to the bottom surface of the fixed frame 102. A socket hole is opened on the bottom surface of the bracket 201, and a plug rod 202 passes through the socket hole. At the top end of the plug rod 202, there is a baffle 203. Specifically, the floating box 204 adopts a hollow structure, which can provide buoyancy for the floating of the plant tray 1. By inserting the bottom end of the plug rod 202 into the bottom of the water body, the limit of the bracket 201 is realized, and then the limit of the plant tray 1 is realized, preventing it from floating around.

[0037] When the device of this embodiment is in use, first, the floating box 204 is filled with gas, and the plug rod 202 is passed through the socket hole at the bottom of the bracket 201. The plant tray 1 is placed on the water surface, and the plug rod 202 is inserted into the bottom of the water body to position the plant tray 1. The staggered arrangement of the animal breeding cage 104 and the plant bucket 101 can prevent the mutual occlusion between animals and plants from affecting the purification effect of the water body. Ryegrass can absorb elements such as nitrogen and phosphorus in the water body to prevent water eutrophication. The snails are used to suck bacteria and organic debris in the sludge, and the snails feed on food residues and nutrients in the water, which can improve the water quality and increase the transparency of the water body.

[0038] Second Embodiment

[0039] Please refer to Figure 1-9 , based on an aquatic animal and plant composite floating bed provided in the first embodiment. During the actual use process, especially in windy weather, the wind will blow the plant tray 1, affecting the firmness of the plug rod 202. And when the wind is strong, it will damage the aquatic plants on the plant tray 1, affecting the normal growth of the aquatic plants and even causing the death of the aquatic plants. At the same time, it will affect the stability of the overall structure and the service life. In addition, when the dissolved oxygen content in the water body is low, it will affect the normal growth of aquatic animals and plants and cause the death of aquatic animals and plants. In addition, after long-term use, there will be more floating objects attached to the roots of the aquatic plants and around the animal breeding cage 104, which will also seriously affect the survival of aquatic animals and plants. To solve the above problems:

[0040] At the bottom surface of the animal breeding cage 104, there is a dissolved oxygen sensor 105. Specifically, the dissolved oxygen sensor 105 is used to monitor the dissolved oxygen content in the water body.

[0041] The inner side of the floating box 204 is horizontally and slidably fitted with a movable plate 205. In the middle of the surface of the movable plate 205, there is a telescopic tube 206. At the top of the telescopic tube 206, there is a fixed seat 207 penetrating the top surface of the floating box 204. In the middle of the fixed seat 207, there is an air supply pipe 208 communicating with the port of an external air pump. Specifically, the external air pump can supply air into the telescopic tube 206 or exhaust air from the telescopic tube 206 through the air supply pipe 208, so as to realize the sliding of the movable plate 205 inside the floating box 204.

[0042] On the corresponding positions of the top parts on both sides of the floating box 204, there are auxiliary components 3. The auxiliary components 3 include side seats 301. On the side seats 301, there are evenly arranged air jet pipes 304. The side seats 301 are symmetrically arranged on the top parts on both sides of the floating box 204. On the side surface of the side seat 301, there is a branch pipe 302 communicating with the floating box 204. At the top of the branch pipe 302, there is a shunt pipe 303. The shunt pipe 303 is communicated with each of the evenly arranged air jet pipes 304. Specifically, the gas in the upper part of the floating box 204 enters each air jet pipe 304 through the branch pipe 302 and the shunt pipe 303 and is discharged through the second exhaust check valve 305, so as to realize aeration in the water body, increase the dissolved oxygen content in the water body, and at the same time, can remove the floating objects gathered around the roots of aquatic plants and the animal breeding cage 104.

[0043] At the end of the air jet pipe 304, there is a second exhaust check valve 305. The branch pipe 302 is inclined. On the branch pipe 302, there is a third underwater solenoid valve 306. The input end of the third underwater solenoid valve 306 is electrically connected to the output end of an external controller. Specifically, the second exhaust check valve 305 can realize the discharge of gas from the air jet pipe 304 to the outside, while the external water cannot enter the air jet pipe 304.

[0044] On the outside of the fixed frame 102, there is a protection component 4. The protection component 4 includes a telescopic floating bladder 403 arranged at the bottom of the fixed frame 102. Specifically, the telescopic floating bladder 403 is filled with gas in the initial state, and the telescopic floating bladder 403 provides buoyancy for the protection frame 402, so as to realize that in the initial state, the middle part of the inner side of the protection frame 402 corresponds to the middle part of the outside of the fixed frame 102, and prevent the sundries floating in the water body from attaching to the plant tray 1 and affecting the growth of aquatic plants.

[0045] A protective frame 402 is provided at the top of the telescopic floating bladder 403. Specifically, the protective frame 402 is made of metal and can sink to the bottom of the water body when placed on the water body. A square frame 401 is slidably fitted inside the protective frame 402, and an electromagnetic bolt corresponding to the square frame 401 is provided on the side of the protective frame 402. Specifically, the electromagnetic bolt can insert its bolt rod into the pin hole on the square frame 401 correspondingly, so as to realize the positioning of the protective frame 402 on the square frame 401. The square frame 401 is fixedly sleeved on the outer middle part of the fixed frame 102. A hose 404 is provided at the bottom of the telescopic floating bladder 403, and the end of the hose 404 is connected to the end of the side pipe 212. Communication pipes 405 are provided on both sides of the square frame 401, and the bottom end of the communication pipe 405 is connected to the end of the connecting pipe 211. Specifically, the protective frame 402 is slidably fitted with the square frame 401, and under the action of the telescopic floating bladder 403, the protective frame 402 can float up and down. The connection between the hose 404 and the side pipe 212 can realize the entry of gas from the top of the floating box 204 into the telescopic floating bladder 403 or the entry of gas from the telescopic floating bladder 403 into the floating box 204. The communication pipe 405 can realize the connection between the floating box 204 and the external atmosphere through the connection of the connecting pipe 211 and the communication pipe 405.

[0046] An intake check valve 209 and a first exhaust check valve 210 are respectively provided on both sides of the top surface of the floating box 204. Connecting pipes 211 are provided on the tops of the intake check valve 209 and the first exhaust check valve 210, and a side pipe 212 is provided on the side of the connecting pipe 211. Specifically, the intake check valve 209 can realize the entry of gas from the connecting pipe 211 into the floating box 204, and the gas cannot enter the connecting pipe 211 from the intake check valve 209. The first exhaust check valve 210 on the other side can realize the discharge of gas from the floating box 204 into the connecting pipe 211 at the top, and the gas cannot enter the floating box 204 from the connecting pipe 211.

[0047] A first underwater solenoid valve 213 is provided at the top of the connecting pipe 211, a second underwater solenoid valve 214 is provided on the side of the side pipe 212, a water pipe 215 is provided on the bottom surface of the floating box 204, and a filter cover 216 is provided at the end of the water pipe 215. Specifically, the first underwater solenoid valve 213 and the second underwater solenoid valve 214 can respectively control the opening and closing of the connecting pipe 211 and the side pipe 212. The water pipe 215 can realize the discharge or entry of water in the water body into or from the floating box 204, and the filter cover 216 is used for filtering the water entering the floating box 204.

[0048] The dissolved oxygen sensor 105 is bidirectionally electrically connected to an external controller. The input ends of the first underwater solenoid valve 213, the second underwater solenoid valve 214, and an air pump located outside are electrically connected to the output end of the external controller respectively. And the external controller is bidirectionally electrically connected to a wind monitoring module located outside. Specifically, the air pump located outside can supply air into and exhaust air from the telescopic tube 206 by connecting with the air supply pipe 208. The wind monitoring module located outside is used to monitor the magnitude of the external wind in real time.

[0049] When the device of this embodiment is in use, in the initial state, the movable plate 205 is located on the inner bottom surface of the floating box 204. At this time, the external air pump discharges the gas in the telescopic tube 206 through the air supply pipe 208. The contraction of the telescopic tube 206 drives the movable plate 205 to slide upward. As Figure 4 shown, the movable plate 205 is located in the middle of the inner side of the floating box 204. While the movable plate 205 slides upward, since the space at the bottom of the movable plate 205 increases, under the action of the water pipe 215, part of the water is pumped into the floating box 204. And while the movable plate 205 slides upward, the second underwater solenoid valve 214 on the first exhaust check valve 210 is closed, and the first underwater solenoid valve 213 on the first exhaust check valve 210 is opened. Then, while the movable plate 205 slides upward, the gas in the floating box 204 is discharged into the external air through the communication pipe 405. And in the initial state, the telescopic floating bladder 403 is filled with part of the gas to provide buoyancy for the protective frame 402. The middle part of the inner side of the protective frame 402 corresponds to the middle part of the outer side of the fixed frame 102. And under the action of the electromagnetic bolt, the protective frame 402 is positioned outside the square frame 401. At this time, the protective frame 402 can protect the plant tray 1, preventing the surrounding floating objects from approaching or attaching to the plant tray 1.

[0050] Secondly, when the external wind monitoring module monitors that the wind starts and the wind speed is less than the threshold set by the wind monitoring module, the wind speed at this time will cause the water surface to fluctuate, and then cause the plant tray 1 to float in the horizontal and vertical directions, which will affect the firmness of the insertion rod 202 inserted into the bottom of the water body. At this time, the external air pump is used to pump gas into the air supply pipe 208, so that the telescopic tube 206 extends to drive the movable plate 205 to move downward. Part of the liquid at the bottom of the movable plate 205 is discharged. At the same time, the electromagnetic bolt is activated to retract the bolt, releasing the positioning of the protective frame 402 on the square frame 401, and closing the first underwater solenoid valve 213 on the intake check valve 209 and the first underwater solenoid valve 213 and the second underwater solenoid valve 214 on the first exhaust check valve 210, and opening the second underwater solenoid valve 214 on the intake check valve 209. Thus, while the movable plate 205 slides downward, the gas in the telescopic floating bladder 403 can be extracted, reducing the amount of gas in the telescopic floating bladder 403 and causing it to contract, making the telescopic floating bladder 403 in the state as Figure 8The state shown. At this time, the buoyancy of the telescopic floating bladder 403 on the protective frame 402 decreases, and the protective frame 402 slides downward. At the same time, the amount of gas in the floating box 204 above the movable plate 205 increases, and the amount of liquid at the bottom of the movable plate 205 decreases. The increased buoyancy of the floating box 204 causes the plant tray 1 to float upward. At this time, the protective frame 402 and the plant tray 1 are in the state as shown in Figure 8 The state shown. The sinking of the protective frame 402 can reduce the windward area outside the protective frame 402, and at the same time increase the contact area between the protective frame 402 and the water body, thereby increasing the resistance of the plant tray 1 to float in the horizontal direction and reducing the floating amplitude of the plant tray 1 in the horizontal direction. At the same time, the sinking of the protective frame 402 will exert a downward pulling force on the plant tray 1, thereby increasing the floating resistance of the plant tray 1 in the vertical direction and reducing the floating amplitude, so as to effectively improve the stability of the plant tray 1 and prevent the plug rod 202 from loosening when inserted into the bottom of the water body.

[0051] However, when the external wind monitoring module detects an increase in the current wind force and the wind speed is greater than the threshold set by the wind monitoring module, at this time, the wind force will damage the aquatic plants on the plant tray 1, and the large wind force will cause large waves on the water surface. After the waves hit the plant tray 1, they will cause great damage to the structure of the aquatic plants and the plant tray 1. At this time, the external air pump is used to contract the telescopic tube 206 through the air supply pipe 208 to drive the movable plate 205 to move upward. At the same time, the first underwater solenoid valve 213 on the first exhaust check valve 210 and the first underwater solenoid valve 213 and the second underwater solenoid valve 214 on the intake check valve 209 are closed, and the second underwater solenoid valve 214 on the first exhaust check valve 210 is opened. At this time, the gas discharged by the upward movement of the movable plate 205 enters the side pipe 212 through the first exhaust check valve 210 and then enters the telescopic floating bladder 403, causing the telescopic floating bladder 403 to elongate and increasing the buoyancy of the protective frame 402. At this time, the state of the telescopic floating bladder 403 and the protective frame 402 is as shown in Figure 9 The state shown. At the same time as the movable plate 205 moves upward, it will draw water from the water body through the water pipe 215, and the filter cover 216 filters the water entering the floating box 204. After the water enters the inside of the floating box 204, the weight of the floating box 204 increases and it sinks. By cooperating with the upward floating of the protective frame 402, the state as shown in Figure 9In the state shown in the figure, the sinking of the floating box 204 will drive the plant tray 1 to sink, so that the surface of the plant tray 1 is located below the liquid surface of the water body. At the same time, the floating of the protective frame 402 can effectively prevent the waves from hitting the plant tray 1. Therefore, the sinking of the plant tray 1 and the floating of the protective frame 402 can effectively prevent the wind from directly acting on the aquatic plants on the plant tray 1, thereby achieving effective protection of the aquatic plants. In addition, under the action of the telescopic floating bag 403 extending downward, it can ensure that the protective frame 402 has enough contact area with the water body, thereby improving the horizontal The buoyancy box 204 can also reduce the resistance in the vertical direction, thereby reducing the swing amplitude of the plant tray 1 in the horizontal direction and maintaining the stability of the overall structure. At the same time, the center of gravity of the overall structure can be effectively lowered under the action of the sinking of the buoyancy box 204, and the swing amplitude of the plant tray 1 in the vertical direction can be reduced. Then, when the wind is strong, the wind can be effectively prevented from damaging the aquatic plants on the plant tray 1, and the waves can be prevented from hitting the plant tray 1 to damage the aquatic plants and the structure of the plant tray 1, and the overall structure can still maintain good stability when the wind is strong.

[0052] In addition, affected by weather changes, the dissolved oxygen content in the water body will also change greatly. When the dissolved oxygen content in the water body is low, it will seriously affect the normal growth of aquatic plants and animals, and even cause the death of aquatic plants and animals. When there are more floating objects gathered around the plant planting barrel 101 and the animal breeding cage 104, the dissolved oxygen content in the area will also be reduced. Therefore, when the dissolved oxygen sensor 105 detects that the dissolved oxygen content in the area where the dissolved oxygen sensor 105 is located is less than the set threshold, Figure 7On the basis of the state shown in the figure, the intermittent air extraction and air supply of the external air pump are utilized to make the telescopic tube 206 slightly extend and retract. Meanwhile, during the air extraction process of the external air pump, the telescopic tube 206 contracts to drive the movable plate 205 to move upward. The first underwater solenoid valve 213 and the second underwater solenoid valve 214 on the air intake check valve 209 and the first exhaust check valve 210 are both closed, and the third underwater solenoid valve 306 is opened. Then, when the movable plate 205 moves upward, air is exhausted into the water body through the jet pipe 304 and the second exhaust check valve 305, thereby achieving an aeration effect, realizing oxygenation in the water body, and increasing the dissolved oxygen content in the water body. Meanwhile, water is pumped into the buoyancy tank 204 through the water pipe 215. During the air supply process of the external air pump into the telescopic tube 206, the telescopic tube 206 extends to drive the movable plate 205 to move downward. Meanwhile, the second underwater solenoid valve 214 on the air intake check valve 209 and the first exhaust check valve 210 are both closed. The first underwater solenoid valve 213 and the second underwater solenoid valve 214 are closed, and the first underwater solenoid valve 213 on the air intake check valve 209 is opened, and then when the movable plate 205 moves downward, external gas can be drawn into the buoyancy box 204 through the connecting pipe 405, and at the same time, the water at the bottom of the movable plate 205 is discharged into the external water body through the water pipe 215. Since the volume of the gas and liquid in the buoyancy box 204 changes during the intermittent air extraction and air supply process of the external air pump, the buoyancy of the buoyancy box 204 also fluctuates accordingly, and then the buoyancy box 204 can be up and down, thereby realizing the up and down floating of the plant carrier 1 and the animal breeding cage 104, so that the floating objects attached to the roots of the aquatic plants and the animal breeding cage 104 can be removed, and at the same time, the gas exposed from the second exhaust check valve 305 can be used to push the detached floating objects away from the roots of the aquatic plants and the surroundings of the animal breeding cage 104 by the impact force of the gas.

[0053] Therefore, when the wind blows, the present invention can use an external air pump to control the extension of the telescopic tube 206 to discharge the gas in the telescopic float 403 into the float box 204, so that the protection frame 402 slides downward, thereby increasing the contact area between the protection frame 402 and the water and then increasing the resistance in the horizontal direction, and using the gravity of the protection frame 402 itself to effectively improve the stability of the plant carrier 1; in addition, when the wind force increases, the external air pump can be used to control the contraction of the telescopic tube 206 to inflate the telescopic float 403, so that the protection frame 402 floats up At the same time, the buoyancy box 204 sinks, thereby improving the wind and wave resistance of the plant carrier 1, and effectively ensuring the stability of the plant carrier 1. In addition, when the dissolved oxygen content in the water body around the aquatic plants and animals is low, the air suction and air supply of the external air pump are used to control the up and down sliding of the movable plate 205, and then the water body can be aerated through the jet pipe 304 and the second exhaust check valve 305 to increase the dissolved oxygen content in the water body. At the same time, the buoyancy box 204 can be made to rise and fall to detach floating objects attached to the roots of aquatic plants and animal breeding cages 104.
