Description

Technical Field

[0001] The utility model relates to the technical field of algae treatment ships, and particularly relates to an algae treatment ship for lake and reservoir basins. Background Art

[0002] Blue-green algae, also known as cyanobacteria, are usually divided into Chroococcales, Oscillatoriales, Nostocales, and Chamaesiphonales. Among them, Oscillatoriales are usually filamentous. Blue-green algae often reproduce in large numbers in summer, forming "water blooms" or "green tides", which cause water quality deterioration. In severe cases, they deplete the oxygen in the water and cause fish deaths. When blue-green algae appear on the water surface of lake and reservoir basins, they need to be treated in time. An algae treatment ship is usually used for treatment. The algae treatment ship usually consists of a hull, a water pump, and an oxygen generator. The water pump operates to filter the water containing blue-green algae through a filter plate and then enter the interior of the hull. The oxygen generator generates oxygen and injects it into the water flow, inhibiting the growth of algae by supplementing oxygen to the water body and realizing the treatment of blue-green algae.

[0003] During the operation of common algae treatment ships for lake and reservoir basins, when water enters the ship body, it needs to be filtered by a filter plate first and then further processed. Currently, most filter plates are structures with filter holes opened on the surface of plate-shaped objects. The Oscillatoriales in blue-green algae have a filamentous structure. When these filamentous blue-green algae pass through the filter holes of the filter plate, they are easily intercepted and hung on the filter holes. As the treatment ship continues to operate, the filamentous blue-green algae hanging on the filter holes gradually increase, and the filter holes of the filter plate will gradually become blocked, thus affecting the subsequent treatment of blue-green algae. Therefore, this application provides an algae treatment ship for lake and reservoir basins to meet the needs. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an algae treatment ship for lake and reservoir basins to solve the technical problem that when filamentous blue-green algae pass through the filter holes of the filter plate, they are easily intercepted and hung on the filter holes, and when the filamentous blue-green algae hanging on the filter holes gradually increase, they will block the filter holes, thus affecting the subsequent treatment of blue-green algae.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] An algae treatment ship for lake and reservoir basins includes a hull. Inside the hull, a water pump, an oxygen generator, an ozone generator, and a hydroxyl generator are respectively installed. The water outlet of the water pump is communicated with the water outlet of the hull through a drainage pipeline. The gas outlet of the oxygen generator is communicated with the gas inlet of the ozone generator. The gas outlet of the ozone generator is communicated with the gas inlet of the hydroxyl generator. The gas outlet of the hydroxyl generator is communicated with the water outlet of the hull. A filtering mechanism is arranged at the water inlet of the hull, and a drainage mechanism is arranged at the water outlet of the hull;

[0007] The filtering mechanism includes a bracket fixed to the top of the hull. A driving member is fixed to the top of the bracket. The telescopic end of the driving member is fixed with a filter plate. A plurality of filter grooves are formed on the side surface of the filter plate, and the filter grooves are strip-shaped.

[0008] Preferably, the filter plate is bent toward the water incoming direction of the hull.

[0009] Preferably, V-shaped surfaces are formed at the top and bottom of the inner wall of the filter groove.

[0010] Preferably, a plurality of arc-shaped cutters are fixed to one side of the filter plate facing the water incoming direction.

[0011] Preferably, a plurality of recessed portions are formed on the side surface of the arc-shaped cutter. The recessed portions are arc-shaped, and the bending direction of the recessed portions is opposite to the bending direction of the arc-shaped cutter.

[0012] Preferably, blocks are fixed to both ends of the arc-shaped cutter, and the blocks are fixed to the side surface of the filter plate.

[0013] Preferably, the drainage mechanism includes a square sleeve installed at the drainage outlet of the hull. A mounting seat is fixed to the inner wall of the square sleeve. A telescopic member is fixed to the bottom of the mounting seat. A drainage box is slidably connected to the inner wall of the square sleeve. The drainage box is fixed to the telescopic end of the telescopic member. A plurality of water permeable holes are formed on the side surface of the drainage box.

[0014] Preferably, both the driving member and the telescopic member are hydraulic cylinders.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, through the arrangement of the filter plate and the filter grooves, the filter grooves are strip-shaped and formed on the filter plate, which can greatly increase the passing probability of filamentous blue-green algae, effectively prevent the filamentous blue-green algae from hanging at the position of the filter grooves, effectively prevent the blockage of the filter grooves, and thus ensure the stable progress of subsequent blue-green algae treatment.

[0017] Through the arrangement of the V-shaped surfaces, the V-shaped surfaces are designed at the filter grooves, which can increase the opening size at the middle position of the filter grooves. On the premise of ensuring the ability of the filter plate to intercept water surface garbage, the passing probability of filamentous blue-green algae through the filter grooves is further increased, thereby further ensuring the stable progress of subsequent blue-green algae treatment.

[0018] Through the arrangement of the arc-shaped cutters, as the water flows into the hull, when filamentous blue-green algae hangs at the position of the filter grooves, the filamentous blue-green algae contacts the arc-shaped cutters, and the arc-shaped cutters can cut off the filamentous blue-green algae, thereby preventing the filamentous blue-green algae from hanging at the position of the filter grooves and further preventing the blockage at the position of the filter grooves.

[0019] Through the arrangement of the recessed part, when the water flow carries filamentous blue-green algae and flows towards the filter tank position, it is guided by the arc-shaped filter plate, and the water flow will flow towards both sides of the filter plate. The recessed part is opened on the arc-shaped cutter. When the filamentous blue-green algae flows on the arc-shaped cutter, it can be promoted to stay on the arc-shaped cutter, so that the filamentous blue-green algae can be stably cut by the arc-shaped cutter under the drive of the subsequent water flow, ensuring that the arc-shaped cutter can play its role stably.

Detailed implementation manners

[0031] The following describes in detail a lake and reservoir basin algae treatment ship provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0032] As Figures 1-8As shown in the figure, an embodiment of the utility model provides an algae treatment ship for a lake and reservoir basin, which includes a hull 1. The hull 1 can be powered by power modules such as solar energy, solid-state batteries, methanol, and hydrogen-based energy. Inside the hull 1, a water pump 2, an oxygen generator 3 (model OZ-20L), an ozone generator 4 (model OZ-100), and a hydroxyl generator 5 (model OZ-NM-50) are respectively installed. The water outlet of the water pump 2 is communicated with the drainage outlet of the hull 1 through a drainage pipeline. The air outlet of the oxygen generator 3 is communicated with the air inlet of the ozone generator 4. The air outlet of the oxygen generator 3 is communicated with the air inlet of the ozone generator 4 through a pipeline. When the oxygen generator 3 starts, it absorbs external air to prepare oxygen. The air outlet of the ozone generator 4 is communicated with the air inlet of the hydroxyl generator 5. The air outlet of the ozone generator 4 is communicated with the air inlet of the hydroxyl generator 5 through a pipeline. The air outlet of the hydroxyl generator 5 is communicated with the drainage outlet of the hull 1. The air outlet of the hydroxyl generator 5 is communicated with the drainage outlet of the hull 1 through a pipeline. A filtering mechanism 11 is provided at the water inlet of the hull 1, and a drainage mechanism 6 is provided at the drainage outlet of the hull 1; the filtering mechanism 11 includes a bracket 18 fixed to the top of the hull 1. A driving member 19 is fixed to the top of the bracket 18. The telescopic end of the driving member 19 is fixed with a filter plate 12. A plurality of filter grooves 13 are formed on the side surface of the filter plate 12. The filter grooves 13 are in a long strip shape. When the water pump 2 starts, water flows in from the water inlet of the hull 1. After the oxygen generator 3 generates oxygen, ozone is generated through the ozone generator 4, and then hydrated hydroxyl ions, that is, hydroxyl oxidation source, are generated by combining with water molecules through the hydroxyl generator 5. The hydroxyl oxidation source is mixed with the water flow to form a mixed solution. The mixed solution can inhibit the growth of algae in the water body and destroy the nuclei of cyanobacteria, realizing the treatment of cyanobacteria. The bracket 18 of the filtering mechanism 11 supports the driving member 19, and the driving member 19 can drive the filter plate 12 to rise and fall, and the position of the filter plate 12 can be adjusted according to the water level and the distribution of algae. The long strip-shaped filter grooves 13 on the filter plate 12 can greatly increase the probability of filamentous cyanobacteria passing through, effectively preventing the filamentous cyanobacteria from hanging at the position of the filter grooves 13 and effectively preventing the filter grooves 13 from being blocked, so as to ensure that the water body continuously and stably flows into the interior of the hull 1 for subsequent treatment.

[0033] As Figure 2 and Figure 5 shown, in this embodiment, the filter plate 12 is bent toward the water incoming direction of the hull 1. When the water flow passes through the filter plate 12, the garbage in the water flow can be dispersed to both sides of the filter plate 12 under the guidance of the bent filter plate 12, thus effectively preventing the garbage from blocking the filter grooves 13 on the filter plate 12.

[0034] As Figure 4 and Figure 5As shown in the figure, in this embodiment, V-shaped surfaces 14 are provided at both the top and bottom of the inner wall of the filtering tank 13. The V-shaped surfaces 14 increase the opening at the middle position of the filtering tank 13. On the premise of ensuring that the filter plate 12 still has the ability to intercept large particulate matters such as floating garbage on the water surface, the possibility of filamentous blue-green algae passing through the filtering tank 13 is further improved, and the probability of filamentous blue-green algae getting caught at the filtering tank 13 is reduced, thereby further ensuring the stable progress of the blue-green algae treatment work.

[0035] As Figures 3-6 shown in the figure, in this embodiment, a plurality of arc-shaped cutters 15 are fixed on one side of the filter plate 12 facing the water inflow direction. As the water flows into the hull 1, when filamentous blue-green algae get caught at the position of the filtering tank 13, the filamentous blue-green algae will come into contact with the arc-shaped cutters 15. The arc-shaped cutters 15 can cut off the filamentous blue-green algae, preventing the filamentous blue-green algae from continuously getting caught at the position of the filtering tank 13, further preventing the blockage of the filtering tank 13, and ensuring the continuous and stable operation of the filtering mechanism 11.

[0036] As Figure 4 shown in the figure, in this embodiment, a plurality of recessed parts 16 are provided on the side surface of the arc-shaped cutter 15. The recessed parts 16 are arc-shaped, and the bending direction of the recessed parts 16 is opposite to the bending direction of the arc-shaped cutter 15. When the filamentous blue-green algae flow on the arc-shaped cutter 15, the recessed parts 16 can intercept the filamentous blue-green algae, causing the filamentous blue-green algae to stay on the arc-shaped cutter 15. Thus, driven by the subsequent water flow, the filamentous blue-green algae can be stably cut off by the arc-shaped cutter 15, ensuring that the arc-shaped cutter 15 can stably play the role of cutting off the filamentous blue-green algae and preventing the filtering tank 13 from being blocked.

[0037] As Figure 4 shown in the figure, in this embodiment, stoppers 17 are fixed at both ends of the arc-shaped cutter 15. The stoppers 17 are fixed on the side surface of the filter plate 12. The stoppers 17 can prevent the filamentous blue-green algae from slipping off both ends of the arc-shaped cutter 15, ensuring that the arc-shaped cutter 15 can effectively play the cutting role, further ensuring that the filtering tank 13 is not blocked by filamentous blue-green algae, and maintaining the normal operation of the filtering mechanism 11.

[0038] As Figure 7As shown, in this embodiment, the drainage mechanism 6 includes a square sleeve 7 installed at the drainage outlet of the hull 1. An installation seat is fixed to the inner wall of the square sleeve 7, and a telescopic member 10 is fixed to the bottom of the installation seat. A drainage box 8 is slidably connected to the inner wall of the square sleeve 7. The drainage box 8 is fixed to the telescopic end of the telescopic member 10. A number of water-permeable holes 9 are formed in the side surface of the drainage box 8. The square sleeve 7 is installed at the drainage outlet of the hull 1 for connecting the hull 1 and the drainage box 8. The mixed liquid enters the drainage box 8 from the square sleeve 7 and then is discharged from the water-permeable holes 9 on the side surface of the drainage box 8. The water-permeable holes 9 are located underwater, and the mixed liquid is discharged from the position of the water-permeable holes 9 to the aggregation area 50 cm below the water surface, which can improve the diffusivity of the hydroxyl oxidation source, thereby further improving the treatment effect on cyanobacteria. The telescopic member 10 can adjust the depth of the drainage box 8 in the water according to the actual situation to meet different usage requirements.

[0039] As Figure 3 and Figure 7 shown, in this embodiment, both the driving member 19 and the telescopic member 10 are hydraulic cylinders. As the driving member 19 and the telescopic member 10, the hydraulic cylinder has the advantages of large output force, stable operation, and high control accuracy. As a hydraulic cylinder, the driving member 19 can stably drive the filter plate 12 to rise and fall, accurately adjusting the position of the filter plate 12. As a hydraulic cylinder, the telescopic member 10 can reliably adjust the depth of the drainage box 8 in the water, ensuring the stable operation of the drainage mechanism 6.

[0040] Working principle: When the algae treatment ship of the utility model operates on the water surface of a lake or reservoir basin, the hull 1 moves forward, and the water pump 2 starts to generate suction, causing lake water to flow into the hull 1 from the water inlet. The water flow first passes through the filtering mechanism 11 for preliminary filtration to prevent surface garbage from entering the interior of the hull 1. Subsequently, the water flow carries cyanobacteria into the interior of the hull 1. After the oxygen generator 3 generates oxygen, ozone is generated by the ozone generator 4. The ozone molecules then effectively combine with water molecules through the hydroxyl generator 5 to produce hydrated hydroxyl ions, that is, hydroxyl oxidation source. Finally, it is discharged together with water from the drainage mechanism 6 at the drainage outlet. The mixed liquid enters the water body to be treated, achieving the inhibition of the growth of algae in the water body, and the mixed liquid has a charge that can directly damage the cyanobacteria cell nucleus, thus realizing the treatment of cyanobacteria; the filter plate 12 in the filtering mechanism 11 is fixed at the telescopic end of the driving member 19. The driving member 19 drives the filter plate 12 to rise and fall, and the position of the filter plate 12 can be adjusted according to the water level and the distribution of algae. The long strip-shaped filter slots 13 opened on the filter plate 12 can greatly increase the probability of filamentous cyanobacteria passing through, effectively preventing the blockage of the filter slots 13, ensuring that the water body can continuously and stably flow into the interior of the hull 1 for subsequent treatment. The V-shaped surfaces 14 opened at the top and bottom of the inner wall of the filter slots 13 increase the opening at the middle position of the filter slots 13. While ensuring that the filter plate 12 still has the ability to intercept large particle substances such as surface garbage, it further improves the possibility of filamentous cyanobacteria passing through the filter slots 13; the arc-shaped cutter 15 is fixed on one side of the filter plate 12 facing the incoming water direction. As the water flows into the interior of the hull 1, when filamentous cyanobacteria hang at the position of the filter slots 13, the filamentous cyanobacteria will contact the blade of the arc-shaped cutter 15, so as to cut the filamentous cyanobacteria with the arc-shaped cutter 15, preventing the filamentous cyanobacteria from continuously hanging at the position of the filter slots 13, and further preventing the blockage of the filter slots 13. The stoppers 17 at both ends of the arc-shaped cutter 15 can prevent the filamentous cyanobacteria from slipping off from both ends, ensuring that the arc-shaped cutter 15 can effectively play the role of cutting; at the same time, when the water flow carries filamentous cyanobacteria and flows towards the position of the filter slots 13, guided by the arc-shaped filter plate 12, the water flow will flow to both sides of the filter plate 12. When the filamentous cyanobacteria flow on the arc-shaped cutter 15, the concave portion 16 can intercept the filamentous cyanobacteria, prompting the filamentous cyanobacteria to stay on the arc-shaped cutter 15. Thus, driven by the subsequent water flow, the filamentous cyanobacteria can be stably cut by the arc-shaped cutter 15, ensuring that the arc-shaped cutter 15 stably plays the role of cutting filamentous cyanobacteria and preventing the blockage of the filter slots 13; the mixed liquid enters the drainage box 8 from the square sleeve 7 of the drainage mechanism 6, and then is discharged from the water permeable holes 9 of the drainage box 8. The water permeable holes 9 are located underwater. The mixed liquid is discharged from the position of the water permeable holes 9 to the aggregation area 50 centimeters below the water surface, thereby improving the diffusibility of the hydroxyl oxidation source, and further improving the treatment effect on cyanobacteria. Moreover, the depth of the drainage box 8 in the water can be adjusted by the telescopic member 10 to adapt to different usage requirements.

[0041] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
