Description

Technical Field

[0001] The present invention relates to the technical field of water ecological restoration, and particularly to a culture tail water restoration system. Background Technique

[0002] Culture tail water is the water discharged after the water quality changes due to factors such as the metabolism of cultured animals, feed residues, drug use, and various biological activities in the water body during the aquaculture process. If the culture tail water is directly discharged without being repaired and purified, it will have a negative impact on the surrounding water environment.

[0003] For the restoration of culture tail water, sedimentation tanks, aeration tanks, biological purification tanks, etc. are generally used, and multiple filter dams are used to complete the restoration of culture tail water. Among them, the biological purification tank often serves as the last checkpoint for the restoration of culture tail water. Through the synergistic action of microorganisms, aquatic animals, and cultivated plants, the pollutants in the culture tail water are degraded, transformed, and absorbed. In a relatively stable environment, plants can carry out stable degradation, transformation, and absorption. However, in the face of harsh environments, such as intense sunlight exposure, it will burn the roots and leaves of plants, and heavy rain will damage the roots and leaves of plants, and it will also cause a sudden rise in water temperature, resulting in the suffocation death of plants, and then the effect of plant restoration of tail water will decline.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1:

[0030] Please refer to Figure 1-8 , a breeding tail water restoration system, including a biological purification tank 1 and a controller. A filling layer 11 is fixed inside the biological purification tank 1. A limiting frame 2 is fixed on one side of the bottom cavity of the biological purification tank 1. A T-shaped frame 21 is slidably connected inside the limiting frame 2. On one side of the two ends of the bottom of the T-shaped frame 21, a first spring 22 is fixed, and one end of the first spring 22 is fixed to the inner wall of the limiting frame 2. A water collection frame 23 is fixed on the top of the T-shaped frame 21. A light-shielding component is arranged on the filling layer 11, and the light-shielding component is used to block light. A water storage component is arranged on the water collection frame 23, and the water storage component is used to collect rainwater;

[0031] The light-shielding component includes a support frame 3. The support frame 3 is located inside the filling layer 11, and the bottom of the support frame 3 is fixed to the biological purification tank 1. A motor 31 is fixed to the bottom of the inner cavity of the support frame 3. The output shaft of the motor 31 is fixed with a support column 32, and the support column 32 is rotatably connected to the support frame 3. A truss 33 is fixed to the top of the support column 32. A storage groove 34 is opened on one side of the truss 33, and the side of the truss 33 close to the storage groove 34 is attached to the water collection frame 23. A folding ceiling 35 is fixed to the inner wall of the truss 33, and one end of the folding ceiling 35 is fixed to the outer wall of the water collection frame 23;

[0032] On the side of the support frame 3 away from the storage groove 34, a mixing tank 4 is opened. An electromagnet 41 is fixed to the side of the mixing tank 4 away from the support column 32. An L-shaped plate 42 is adsorbed on the side of the electromagnet 41 close to the support column 32, and the L-shaped plate 42 is slidably connected to the mixing tank 4. A limiting block 43 is fixed to the side of the mixing tank 4 close to the electromagnet 41. A sliding plate 44 is slidably connected inside the limiting block 43. One end of the sliding plate 44 close to the L-shaped plate 42 is fixed to the L-shaped plate 42. A second spring 45 is fixed to the surface of the limiting block 43 close to the L-shaped plate 42, and one end of the second spring 45 is fixed to the L-shaped plate 42. Floating plates 46 are rotatably connected to both sides of the end of the sliding plate 44 away from the limiting block 43. A plurality of spray pipes 5 are uniformly fixed to the bottom of the side of the truss 33 away from the support column 32, and the spray pipes 5 are communicated with the mixing tank 4;

[0033] During the specific operation process, when the sunlight is too sufficient on sunny days, resulting in too high temperature around the plants on the surface of the filling layer 11, first, the controller starts the motor 31, the motor 31 drives the support column 32 to rotate, the support column 32 drives the truss 33 to rotate, and the truss 33 drives the folding ceiling 35 to rotate around the support column 32;

[0034] In the initial state, the water collecting frame 23 abuts against the truss 33. When the truss 33 rotates, it gradually moves away from the water collecting frame 23, and then the water collecting frame 23 and the T-shaped frame 21 reset under the pulling force of the first spring 22. After resetting, the T-shaped frame 21 and the water collecting frame 23 are limited by the limiting frame 2 and cannot move further. Then, the fixed end of the folding ceiling 35 and the water collecting frame 23 cannot move. As the truss 33 continues to rotate, the truss 33 drives the folding ceiling 35 to extend and open. Until the truss 33 rotates 360 degrees, the truss 33 abuts against the water collecting frame 23 again. Thus, the folding ceiling 35 is extended and stretched into a conical roof and covers the plants on the filling layer 11;

[0035] Thus, in the high-temperature weather in summer, shading operation can be carried out on the plants for repairing aquaculture tail water, avoiding direct sunlight on the roots and leaves of the plants, thereby maintaining the activity of plant photosynthetic enzymes, maintaining the efficiency of organic matter synthesis, further maintaining the efficiency of plant repair of aquaculture tail water, and at the same time avoiding excessive evaporation of water in the biological purification pond 1 resulting in a decrease in water level, and improving the water absorption efficiency of plant roots and rhizomes;

[0036] Further, before the folding ceiling 35 opens, each medicament to be put can be pre-mixed in proportion in the mixing tank 4 according to the measurement ratio. Then, after the controller controls the motor 31 to start, through the above steps, the folding ceiling 35 is controlled to open to form a shield. During the rotation and extension of the folding ceiling 35, the controller controls the electromagnet 41 to make the electromagnet 41 be repeatedly powered on. When the electromagnet 41 is powered on, it generates a suction force on the L-shaped plate 42, causing the L-shaped plate 42 to drive the sliding plate 44 to move towards the direction of the electromagnet 41. During the movement of the L-shaped plate 42, the second spring 45 is stretched. At the same time, during the movement of the sliding plate 44, the floating plates 46 rotatably connected to both sides of the sliding plate 44 are affected by the resistance of the medicament and turn over;

[0037] When the electromagnet 41 is powered off, the L-shaped plate 42 resets under the pulling force of the second spring 45, and then the sliding plate 44 resets. During the reset process of the sliding plate 44, the floating plates 46 are also driven to reset. During the reset process of the floating plates 46, they are also affected by the resistance of the medicament. Then, in the state where the electromagnet 41 is repeatedly powered on, the sliding plate 44 drives the floating plates 46 to be affected by the resistance of the medicament and turn over repeatedly. During the turning process of the floating plates 46, they play a role in uniformly mixing the medicament, making the medicament mixing more thorough;

[0038] During the process of the truss 33 driving the folding ceiling 35 to rotate and extend, the water spray pipe 5 rotates synchronously with the truss 33. Subsequently, the controller controls the water spray pipe 5 to start, and the mixed medicament is evenly put into the interior of the biological purification tank 1 and the surface of the plants in the filling layer 11 in a circular motion. Then, through the comprehensive application of the medicament, the plants on the surface of the filling layer 11 and the microorganisms in the biological purification tank 1 are evenly promoted by the medicament, thereby improving the efficiency of the plants and microorganisms in repairing the aquaculture tail water;

[0039] Furthermore, in rainy weather, the plants in the filling layer 11 can also be protected from rain by the fully opened folding ceiling 35, which avoids the direct impact of rain on the plants planted on the surface of the filling layer 11 and prevents the damage of the plant stems and leaves. At the same time, it plays a role in guiding rainwater, reducing the amount of rainwater directly falling into the biological purification tank 1 and the rising speed of the water level in the biological purification tank 1, thereby avoiding the probability of plant suffocation and death caused by the rising water level in the biological purification tank 1.

[0040] It should be noted that when the overall shape of the biological purification tank 1 is square, during the process of the truss 33 driving the water spray pipe 5 to rotate, some of the water spray pipes 5 will move outside the biological purification tank 1. At this time, if the water spray pipe 5 discharges the medicament, it will cause waste of the medicament. Therefore, in the present invention, debugging is required before the medicament is discharged. When the truss 33 drives the water spray pipe 5 to rotate, the specific angle at which the water spray pipe 5 moves outside the biological purification tank 1 and the specific angle at which the water spray pipe 5 moves back above the biological purification tank 1 can be determined according to the installation position of the water spray pipe 5. Furthermore, the time when the water spray pipe 5 moves outside the biological purification tank 1 and the staying time outside can be determined according to the rotation speed of the motor 31, and then the energization time of the electromagnet 41 can be set;

[0041] After the water spray pipe 5 moves outside the biological purification tank 1, the electromagnet 41 is continuously de-energized, and then the second spring 45 moves above the two water spray pipes 5 closest to the electromagnet 41 under the pulling force of the floating plate 46, forming a shield for the water spray pipe 5 through the L-shaped plate 42, and then the water spray pipe 5 close to the electromagnet 41 is in a closed state, thereby avoiding waste of the medicament.

[0042] Embodiment 2:

[0043] The water storage assembly includes a water storage tank 6, which is opened inside the water collection frame 23. A plurality of nozzles 61 are evenly fixed at the bottom of the water storage tank 6 on the side away from the T-shaped frame 21. A rubber plate 62 is slidably connected inside the water storage tank 6 at the end away from the nozzles 61, and the rubber plate 62 abuts against the inner wall of the water storage tank 6 on the side away from the nozzles 61;

[0044] A threaded rod 7 is internally threaded and connected to the inner part of the water collecting frame 23 near one end of the rubber plate 62, and one end of the threaded rod 7 is located inside the water storage tank 6. A sampling tube 71 is fixed to the end of the threaded rod 7 located inside the water storage tank 6. A push rod 72 is slidably and sealingly connected to the inside of the threaded rod 7. A rubber plug 73 is fixed to the end of the push rod 72 away from the threaded rod 7. The rubber plug 73 is slidably and sealingly connected to the sampling tube 71. A pull plate 74 is fixed to the end of the push rod 72 away from the rubber plug 73, and the pull plate 74 is located outside the water storage tank 6. A sealing plate 75 is fixed to the end of the threaded rod 7 located outside the water storage tank 6, and the sealing plate 75 abuts against the water collecting frame 23;

[0045] Specifically, on the basis of Embodiment 1, during a rainstorm, when the controller controls the folding awning 35 to complete the opening, the folding awning 35 shields and diverts the rainwater. At the same time, the water storage tank 6 can collect the rainwater. While the water storage tank 6 is collecting the rainwater, part of the rainwater backflows into the inside of the sampling tube 71. When the rainy day ends, the pull plate 74 can be pulled, the push rod 72 is pulled through the pull plate 74, and then the rubber plug 73 is driven by the push rod 72 to retract into the inside of the sampling tube 71, thereby sealing the sampling tube 71. Subsequently, the sealing plate 75 is rotated, the pull plate 74 is rotated through the sealing plate 75, and then the threaded rod 7 is disengaged from the water collecting frame 23. Subsequently, the threaded rod 7 and the sampling tube 71 are pulled out from the inside of the water storage tank 6. When the sampling tube 71 is pulled out from the inside of the water storage tank 6, the rubber plate 62 is re-engaged into the inside of the water storage tank 6 under the action of gravity, thereby closing the notch of the water collecting frame 23 with the rubber plate 62;

[0046] Subsequently, the rainwater collected in the sampling tube 71 can be sent for testing to analyze the content of heavy metals, organic substances, and other trace elements contained in the rainfall in the current climate environment, and to evaluate the current ecological environment. Subsequently, if it is detected that the rainwater can be used for spraying and cooling plants, it can be reserved for later use. In the hot summer, it cooperates with the folding awning 35 to block the sunlight, and at noon when the temperature is high, the controller starts the nozzle 61, and the nozzle 61 sprays the rainwater collected in the water storage tank 6 onto the plants on the surface of the filling layer 11 to cool the plants, ensuring the activity of the plants at high temperatures, and thus improving the effect of the plants in the biological purification tank 1 in repairing the aquaculture tail water.

[0047] Embodiment 3:

[0048] A water pump 8 is fixed to the end of the inner cavity of the water storage tank 6 away from the threaded rod 7. A water suction pipe 81 is fixed to the water inlet pipe of the water pump 8, and the water suction pipe 81 passes through the water collecting frame 23. A folding shed 82 is fixed inside the storage tank 34 under the folding awning 35. The other end of the folding shed 82 is fixed to the outer wall of the water collecting frame 23. The end of the water suction pipe 81 away from the water pump 8 is fixed and communicated with the folding shed 82;

[0049] Specifically, based on the first and second embodiments, since the extension and opening of the folding ceiling 35 are completely controlled by the controller, and the biological purification tank 1 is filled with aquaculture tail water, the humidity above the water surface of the biological purification tank 1 increases during the night and early morning. At this time, the folding ceiling 35 can be controlled to fully open, so that the moisture above the water surface of the biological purification tank 1 and above the plants in the filling layer 11 contacts the bottom of the folding ceiling 35 during the rising process. As a result, the moisture condenses into dew on the bottom of the folding ceiling 35. Affected by the conical bottom of the folding ceiling 35, the condensed dew gradually moves along the folding ceiling 35 towards the direction of the folding shed 82 until the dew slides to the edge of the folding ceiling 35 and then falls into the interior of the folding shed 82. Thus, the folding shed 82 plays a role in collecting dew;

[0050] Subsequently, the controller can be used to start the water pump 8, so that the water pump 8 pumps the dew in the folding shed 82 into the interior of the water storage tank 6 through the water suction pipe 81. Then, according to the operation steps of the second embodiment, the dew can be sampled through the sampling pipe 71 and sent for testing. When it is detected that the dew is harmless to the microorganisms in the biological purification tank 1 and the plants planted on the surface of the filling layer 11, the collected dew can be stored in the interior of the water storage tank 6. And according to the steps of the second embodiment, during high temperature, the dew is sprayed on the surface of the plants by the nozzle 61, further saving the water demand for plant cooling and heat dissipation. At the same time, the stability of plant remediation of aquaculture tail water is further improved;

[0051] Furthermore, if the dew obtained in the sampling pipe 71 is detected to have serious heavy metal pollution, then this dew cannot be used for subsequent reuse and needs to be discharged. At the same time, the dew condensed on the leaves of the plants planted on the surface of the filling layer 11 also poses a hazard to the plants;

[0052] Therefore, after the pollutants or toxic substances in the dew exceed the standard, it is necessary to clean the dew on the plants on the surface of the filling layer 11. At this time, the controller can be used to control the rotation of the support column 32. The support column 32 drives the truss 33 to rotate, and the truss 33 drives the water spray pipe 5 to rotate, so that the water spray pipe 5 rotates around the support column 32. During the rotation of the water spray pipe 5, it contacts the leaves of the plants planted on the surface of the filling layer 11. Then, the plants are swept by the water spray pipe 5, causing the plants to touch and shake each other, thereby shaking off the dew on the plant surface, avoiding the long-term stay of the dew on the leaf surface to form concentrated droplets, and avoiding the penetration of the concentrated droplets into the plant body and causing damage to the plants;

[0053] At the same time, it also avoids the blockage of the plant leaf stomata by the salts left after the evaporation of the concentrated droplets, avoiding the decrease in plant stomatal conductance, thereby increasing the lifespan of the plants on the surface of the filling layer 11 and improving the efficiency of plant remediation of the aquaculture tail water in the biological purification tank 1.

[0054] It should be noted that the length of the water spray pipe 5 can be determined according to the height of the plants planted on the surface of the filling layer 11, and it is only necessary to ensure that the water spray pipe 5 can contact the plant leaves.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
