Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a marine aquaculture tailwater treatment device and treatment process. Background Art

[0002] Mariculture refers to aquaculture activities carried out in the ocean or saltwater environment, mainly including the cultivation of aquatic organisms such as fish, shellfish, and algae. Compared with freshwater aquaculture, mariculture usually has a richer variety of organisms and higher economic value. In the aquaculture process, aquaculture tail water is the water discharged after the water quality changes due to factors such as the metabolism of farmed organisms, feed residues, drug use, and various biological activities in the water body. This water usually needs to be treated before it can be safely discharged or reused, and the pollutants in these waters are also easy to adhere to the aquaculture nets, which need to be cleaned regularly. It can help reduce pollution to surrounding waters, protect the health of aquatic organisms, and ensure the sustainable development of the aquaculture industry.

[0003] For example, in the existing Chinese patent with the publication number CN112871815A, a fishing net cleaning device for aquaculture is disclosed, which includes a motor, a threaded screw, a water tank, a fixed base, a fixed steel frame, a water pump, a fixed splint, a nozzle, a connecting frame and a spray device, a water tank is installed at the middle position of the top of the fixed base, and the tops of both sides of the inside of the water tank are provided with first slide rails, and a filter is installed horizontally between the first slide rails. Through the above-mentioned existing technology, the motor drives the driving shaft and the driving wheel to rotate, and the driving wheel drives the driven wheel and the driven shaft to rotate together through the connecting belt, so that the threaded screw rotates at the same speed at the same time, and the threaded screw rotates while driving the threaded sleeve housing and the threaded sleeve to reciprocate up and down together, and the mechanized operation is fast and convenient, which is convenient for cleaning the fishing net.

[0004] However, the above prior art has the following technical defects: When the above-mentioned prior art is used, it is necessary to first remove the fishing net from the breeding area and place it on the fixed clamp. After fixing the fishing net with a fixing clamp, the motor is started to drive the driving shaft and the driving wheel to rotate, driving the threaded screw to drive the threaded sleeve housing and the threaded sleeve to reciprocate up and down, so that the spray device moves together, and the water pump draws water from the water tank through the water pipe to the booster pump for pressurization, and finally sprays it out from the nozzle of the spray device to clean the fishing net. Before cleaning, the fishing net needs to be disassembled and fixed in the above-mentioned device; the disassembly and installation of the fishing net usually require manual operation, which leads to the staff going into the water to disassemble the fishing net, which is easy to cause re-pollution to the breeding water. And the normal breeding progress will be affected when disassembling and installing the fishing net.

[0005] Based on this, on the basis of the existing aquaculture fishing net cleaning device, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-Figure 15 This application is described in further detail.

[0037] The embodiments of the present application disclose a seawater aquaculture tailwater treatment device and a treatment process, which can collect aquaculture water in layers and conduct rapid testing on the collected water. After detecting that the water quality does not meet the requirements, it can be cleaned step by step and automatically without dismantling the aquaculture net, thus avoiding dismantling the aquaculture net as a whole and affecting the aquaculture progress.

[0038] Reference Figure 1 and Figure 2 As shown, in the first aspect, the present application provides a marine aquaculture tailwater treatment device, including a floating platform 1 and a propeller 11 installed on the lower side of the floating platform 1. When the propeller 11 runs forward and reverse, it can drive the floating platform 1 to move forward and backward in the aquaculture waters; a water pump 12 is arranged on the upper side of the floating platform 1, and a processing unit 2 is arranged on the floating platform 1. The floating platform 1 is placed in the aquaculture waters. The processing unit 2 can collect polluted water bodies in the aquaculture waters in layers and quickly detect the collected water bodies. When the water bodies that do not meet the requirements are detected, the aquaculture nets in this depth area can be cleaned step by step and automatically. There is no need to disassemble the aquaculture net as a whole, which has the effect of ensuring the cleanliness of the aquaculture waters without affecting the progress of aquaculture.

[0039] The processing unit 2 includes a hollow tube 21 inserted on the floating platform 1. The floating platform 1 is provided with a round through hole 101 for inserting and placing the hollow tube 21. A U-shaped side seat 23 is installed on one side of the floating platform 1 through two side blocks 22. The U-shaped side seat 23 is fixedly installed on one side of the floating platform 1 through the two side blocks 22, and is the side away from the hollow tube 21. A transmission pipe 24 connected to the water pump 12 is clamped on the outer wall of the U-shaped side seat 23. The water pump 12 has a water inlet and a drain. The transmission pipe 24 is connected to the water inlet of the water pump 12, and an external pipe needs to be connected to the drain end when in use. The other end of the external pipe is placed outside the aquaculture water area. A tubular air bag 26 is provided on the side wall of the floating platform 1 through two hanging plates 25. The inflation of the tubular air bag 26 can increase the buoyancy of the floating platform 1 in the aquaculture water area. A collection and detection component 3 is provided on the hollow tube 21 for performing hierarchical collection and rapid detection of polluted water bodies; a cleaning mechanism 4 is provided on the U-shaped side seat 23 for performing step-by-step automatic cleaning of the aquaculture net.

[0040] When in use, the floating platform 1 is placed in the aquaculture waters and near the edge of the aquaculture net, and the hollow tube 21 is inserted into the round through hole 101 so that the hollow tube 21 extends into the aquaculture waters, and the aquaculture net needs to be in the middle of the U-shaped side seat 23. When the propeller 11 is running, the floating platform 1 can be driven to move on the water surface. The collection and detection component 3 first collects and quickly detects water bodies of different depths in different levels. After detecting water bodies that do not meet the requirements, the cleaning mechanism 4 can automatically clean the aquaculture net in this depth area step by step.

[0041] Reference Figure 3 and Figure 4 As shown, in order to collect and detect polluted water bodies at different depths, the cleaning mechanism 4 is used to clean the designated area of ​​the aquaculture net. The collection and detection component 3 includes five liquid storage bottles 31 arranged in the hollow tube 21 at equal intervals in sequence, and the five liquid storage bottles 31 are fixedly installed in the hollow tube 21; a rectangular end block 32 is clamped at the upper end of the hollow tube 21, and a control round rod 33 is inserted and slidably provided on the rectangular end block 32. A round rod hole 321 for inserting and installing the control round rod 33 is opened through the rectangular end block 32. In this embodiment, preferably, a U-shaped chute 311 adapted to the control round rod 33 is opened on the side wall of the five liquid storage bottles 31, and a liquid inlet hole 312 is opened at the U-shaped chute 311. It should be noted that the upper end of the liquid storage bottle 31 is closed, and the liquid can only enter the inner cavity of the liquid storage bottle 31 through the liquid inlet hole 312. When the control round rod 33 is driven, it can slide up and down at the U-shaped chute 311.

[0042] Reference Figure 5 and Figure 6 As shown, since it is necessary to control water bodies of different depths to enter the liquid storage bottle 31 of the corresponding level synchronously, in this embodiment, five access holes 331 adapted to the liquid inlet hole 312 are preferably opened evenly through the control rod 33, and five rubber protrusions 34 are evenly installed on the side of the control rod 33 facing the liquid storage bottle 31. It should be noted that the position of each rubber protrusion 34 is respectively below each access hole 331, and the shape of the rubber protrusion 34 is adapted to the liquid inlet hole 312. When the control rod 33 is at a certain height and the rubber protrusion 34 is blocked at the liquid inlet hole 312, the external liquid cannot enter the liquid storage bottle 31. When the control rod 33 is driven to slide and the rubber protrusion 34 is separated from the liquid inlet hole 312, the rubber protrusion 34 can be deformed by being squeezed. A spring rod 35 connected to the bottom of the control round rod 33 is provided at the bottom of the hollow tube 21. The spring rod 35 always has a driving force to push the hollow tube 21 upward, and the upward pushing stroke is certain. When there is no other external force, the spring rod 35 pushes the hollow tube 21 to the highest point, and the five rubber protrusions 34 are respectively blocked at the liquid inlet holes 312 on the five liquid storage bottles 31. The upper end of the hollow tube 21 has a hanging part 36, and a mounting plate 37 is provided on one side of the hanging part 36. A portable detector 38 is placed on the mounting plate 37, and the portable detector 38 can detect the water body.

[0043] When it is necessary to collect water, the control rod 33 is pressed downward so that the upper end of the control rod 33 is flush with the upper side of the rectangular end block 32. At this time, the five access holes 331 on the control rod 33 overlap with the liquid inlet holes 312 on the five liquid storage bottles 31 respectively, so as to achieve the effect of opening the liquid inlet holes 312. Water bodies of different depths can enter the liquid storage bottle 31 through the liquid inlet holes 312 on the liquid storage bottles 31 at different depths, so as to achieve the effect of hierarchical water collection. After the collection is completed, the control rod 33 is released, and the control rod 33 slides upward and resets under the drive of the spring rod 35, and the rubber protrusion 34 is re-blocked at the liquid inlet hole 312, and then the hanging part 36 is pulled upward to extract the hollow tube 21, and the water collected in each liquid storage bottle 31 is quickly tested in turn using the portable detector 38.

[0044] Reference Figure 7 and Figure 8 As shown, considering the need to clean the pollutants attached to the aquaculture net and to ensure the cleanliness of the aquaculture water body without disassembling the aquaculture net as a whole and without affecting the aquaculture progress, the cleaning mechanism 4 includes two rectangular covers 42 symmetrically limited and slidably arranged on the inner wall of the U-shaped side seat 23 through the side square blocks 41. It should be noted that the two rectangular covers 42 have a certain spacing to facilitate placing the floating platform 1 in the aquaculture water area. When the aquaculture net is in the U-shaped side seat 23, the upper edge of the aquaculture net is located between the two rectangular covers 42; the inner side of the U-shaped side seat 23 is symmetrically provided with rectangular slide grooves 231 for limiting the installation of the square blocks 41 on both sides, and a folding hose 43 connected to the transmission pipe 24 is installed on one side of the rectangular cover 42, and the folding hose 43 can be stretched under force.

[0045] The U-shaped side seat 23 is located at the rectangular chute 231 and is rotatably installed with a bidirectional screw rod 44 that is threaded through the side square block 41, and the upper end of the bidirectional screw rod 44 penetrates the U-shaped side seat 23 and extends upward. The side square block 41 is penetrated with an internal threaded hole 411 that is adapted to the bidirectional screw rod 44, and the U-shaped side seat 23 is provided with an extension hole 232 that is connected to the rectangular chute 231 and is penetrated by the upper end of the bidirectional screw rod 44. When the two bidirectional screw rods 44 are rotated by the driving force, they can cooperate with the internal threaded hole 411 opened on the side square block 41 to drive the rectangular cover 42, and can drive the rectangular cover 42 to extend downward into the breeding water, and move upward to reset.

[0046] Reference Fig. 9As shown, a two-end abutting cylinder 45 is symmetrically mounted in a rectangular cover 42, and a mounting circular hole 421 for mounting the end abutting cylinder 45 is provided on the rectangular cover 42. A cleaning roller 46 is arranged between the two end abutting cylinders 45, and the two end abutting cylinders 45 and the cleaning roller 46 are fixedly connected; the cleaning roller 46 has cleaning bristles 47. It should be noted that the cleaning bristles 47 are relatively long. Although there is a gap between the two rectangular covers 42, when the breeding net is located between the two rectangular covers 42, the cleaning bristles 47 can contact the breeding net. When the cleaning roller 46 is rotated by the driving force, the pollutants attached to the breeding net can be cleaned by the cleaning bristles 47.

[0047] Reference Fig. 9 and Fig.10 As shown, an end round rod 48 is symmetrically rotatably mounted on the U-shaped side seat 23, and a round rod rotation hole 233 for mounting the end round rod 48 is symmetrically opened on the U-shaped side seat 23. A square control rod 49 is set at the bottom of the end round rod 48 to penetrate the end cylinder 45 and the cleaning roller 46, and a square hole 451 is opened on the end cylinder 45 and the cleaning roller 46 for the square control rod 49 to penetrate. The end round rod 48 and the square control rod 49 are fixedly connected. When the end round rod 48 is rotated by force, the end cylinder 45 and the cleaning roller 46 can be driven to rotate by the square control rod 49.

[0048] Reference Fig.11 As shown, in order to drive the two bidirectional screw rods 44 and the two end round rods 48 respectively, so that the two rectangular covers 42 can be lowered to different depths, and at the same time, the cleaning rollers 46 installed in the two rectangular covers 42 can be driven to rotate, a driving assembly 5 is provided on the U-shaped side seat 23, and the driving assembly 5 includes a driving motor 51 installed on the U-shaped side seat 23, and an inner groove 234 for installing the driving motor 51 is provided on the U-shaped side seat 23. The U-shaped side seat 23 is covered with an end cover plate 52 at the inner groove 234. It should be noted that the rotating shaft of the driving motor 51 is set to penetrate the end cover plate 52 upward; the rotating end of the driving motor 51 is sleeved with a driving gear 53. The driving motor 51 is installed on the U-shaped side seat 23 in a hidden manner.

[0049] Continue to refer to Fig.11As shown, a lateral round rod 54 is rotatably mounted on the upper side of the end cover plate 52, and a double groove wheel 55 and a ratchet gear 56 are sleeved on the lateral round rod 54, and the ratchet gear 56 is meshed with the driving gear 53, and a transmission belt 57 is sleeved between the double groove wheel 55 and the extended end of the bidirectional screw rod 44. When the driving motor 51 rotates forward, it can drive the ratchet gear 56 to rotate through the driving gear 53, that is, drive the lateral round rod 54 and the double groove wheel 55 to rotate, and the two transmission belts 57 sleeved on the double groove wheel 55 can drive the two bidirectional screw rods 44 to rotate. When it is detected that the water quality at a certain depth does not meet the requirements, the driving motor 51 is started to rotate forward to drive the two bidirectional screw rods 44 to rotate, so as to synchronously drive the two rectangular covers 42 to slide downward and extend into the corresponding depth in the aquaculture water. At this time, the folding hose 43 will be elongated due to the downward movement of the two rectangular covers 42, and the two rectangular covers 42 are respectively located on both sides of the aquaculture net.

[0050] Reference Fig.12 As shown, a lateral round rod 58 is rotatably mounted on the upper side of the end cover plate 52, and a double groove wheel 59 and a ratchet gear 591 are sleeved on the lateral round rod 58, and the ratchet gear 591 is meshed with the driving gear 53, and a transmission belt 592 is sleeved between the double groove wheel 59 and the end round rod 48. After the two rectangular covers 42 are driven to descend to the corresponding depth, the driving motor 51 is started to rotate in the opposite direction, and at this time, the driving gear 53 can drive the ratchet gear 591 to rotate, that is, the lateral round rod 58 and the double groove wheel 59 are driven to rotate, and the two transmission belts 592 sleeved on the double groove wheel 59 can drive the two end round rods 48 to rotate, and the square control rod 49 installed at the lower end of the two end round rods 48 drives the end cylinder 45 and the cleaning roller 46 to rotate, and the cleaning bristles 47 on the cleaning roller 46 can clean the pollutants attached to the breeding net. At the same time, the water pump 12 is started to pump out the sewage in the rectangular cover 42 area through the foldable hose 43, and discharge it to the outside of the aquaculture waters through the external pipe.

[0051] Reference Fig.13 and Fig.14As shown, on the basis of the first embodiment, in order to limit the pollutants originally attached to the aquaculture net when cleaning the aquaculture net, the pollutants can be placed in two rectangular covers 42 and then pumped out by the water pump 12 to prevent the pollutants from being dispersed to other areas. The rectangular cover 42 is also provided with an extension unit 6 that cooperates with the rotating end-end cylinder 45. The extension unit 6 includes a telescopic frame 61 installed on one side of the rectangular cover 42. The telescopic frame 61 is a soft folding setting and can expand outward when subjected to force; side rollers 62 are symmetrically rotatably installed on the telescopic frame 61, and raised blocks 63 are symmetrically arranged on the telescopic frame 61. The raised blocks 63 are provided with a push ball 65 on one side of the inner cavity of the rectangular cover 42 through a cylindrical seat 64 for limited rotation. The two end-end cylinders 45 located in the rectangular cover 42 are provided with raised wheels 66 that cooperate with the push ball 65. The raised wheel 66 is fixedly mounted on the end-end cylinder 45. When the end-end cylinder 45 is driven to rotate, the raised wheel 66 can rotate synchronously.

[0052] A U-shaped frame rod 67 is fixedly sleeved on the cylindrical seat 64, and two limit round rods 68 are inserted and slidably provided on the U-shaped frame rod 67, and one end of the limit round rod 68 is fixedly connected to the inner wall of the rectangular cover 42, and a reset spring 69 is sleeved on the limit round rod 68. The reset spring 69 always has a driving force to push the U-shaped frame rod 67 toward the inner cavity of the rectangular cover 42. That is, in the absence of other external forces, the telescopic frame 61 is always in a retracted state. At this time, although the telescopic frame 61 and the side roller 62 are installed at the opening of the two rectangular covers 42, there is still a certain distance between the two rectangular covers 42 to ensure that the upper edge of the breeding net can be between the two rectangular covers 42 when the equipment is placed. It should be noted that in the initial state, driven by the reset spring 69, the ball bearing 65 is pushed to be in the recess of the raised wheel 66, so that the telescopic frame 61 is in a retracted state.

[0053] Since the two rectangular covers 42 have a certain distance, the pollutants cleaned from the aquaculture net are easily dispersed and flow out of the cover area of ​​the rectangular cover 42, and cannot be pumped out by the water pump 12, which means that when the aquaculture net is cleaned, it will also cause secondary pollution to the aquaculture waters. Therefore, it is necessary to prevent the pollutants from flowing out of the rectangular cover 42. When the end-end cylinder 45 and the cleaning roller 46 are driven to rotate, which means that the aquaculture net is being cleaned at this time, the raised wheel 66 rotates rapidly following the end-end cylinder 45, and the raised part of the raised wheel 66 can drive the push ball 65 to move toward the middle of the two rectangular covers 42, thereby driving the telescopic frame 61 to extend outward, so that one side of the telescopic frame 61 can contact the aquaculture net to prevent the pollutants from flowing out of the rectangular cover 42. The side roller 62 can reduce the friction effect when the telescopic frame 61 contacts the aquaculture net when the propeller 11 drives the floating platform 1 to move, so as to drive the U-shaped side seat 23 to move as a whole.

[0054] Reference Fig.15As shown, on the other hand, the present application also discloses a marine aquaculture tail water treatment process, the treatment process comprising the following steps: S1, equipment placement: When in use, the floating platform 1 is placed in the aquaculture waters, so that the hollow tube 21 is in the aquaculture waters, the aquaculture net is in the U-shaped side seat 23; the upper edge of the aquaculture net is located between the two rectangular covers 42. The external pipe is connected to the drain outlet of the water pump 12, and the other end of the external pipe is placed outside the aquaculture waters.

[0055] S2, collection and testing: the collection and testing component 3 on the hollow tube 21 collects the aquaculture water in different levels and performs a rapid test on the collected water; specifically, during collection, the control rod 33 is pressed downward to make the access hole 331 on the control rod 33 coincide with the liquid inlet hole 312, and the water enters the liquid storage bottle 31 through the liquid inlet hole 312. After the collection is completed, the rubber protrusion 34 of the control rod 33 is released to re-seal the liquid inlet hole 312, the hollow tube 21 is pulled out upward, and the water collected in the liquid storage bottle 31 is quickly tested using the portable detector 38.

[0056] S3, mobile cleaning: after detecting the water body that does not meet the requirements, the cleaning mechanism 4 on the U-shaped side seat 23 cooperates with the propeller 11 to drive the floating platform 1 to automatically clean the aquaculture net in this area; when it is detected that the water quality at a certain depth does not meet the requirements, the drive motor 51 is started to rotate forward to drive the two rectangular covers 42 to descend to the corresponding depth in the aquaculture water. Then the drive motor 51 is controlled to rotate in the reverse direction, so that the drive end abuts the cylinder 45 and the cleaning roller 46 to rotate, and the cleaning bristles 47 on the cleaning roller 46 are used to clean the pollutants on the aquaculture net.

[0057] S4, debris extraction: At the same time, the water pump 12 cooperates with the cleaning mechanism 4 to extract the pollutants that appear during cleaning to prevent them from remaining in the aquaculture waters. When the end-end cylinder 45 and the cleaning roller 46 rotate, the raised wheel 66 quickly rotates following the end-end cylinder 45, and drives the telescopic frame 61 to expand outwards through the contact with the push-end ball 65. One side of the telescopic frame 61 contacts the aquaculture net. When the water pump 12 is started, the sewage in the rectangular cover 42 area can be extracted and discharged to the outside of the aquaculture waters through the external pipe.

[0058] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
