Description

Technical Field

[0001] This invention relates to the field of ecological and environmental protection technology, and in particular to a device for collecting algae in water. Background Technology

[0002] In the existing technology, there are various types of algae harvesting vessels. These vessels are relatively large and are only suitable for navigating large bodies of water such as rivers and lakes (e.g., water widths of more than 10 meters). Furthermore, they are difficult to operate if multiple turns are required over short distances. The algae harvesting equipment installed on the vessels is also large and only suitable for large-area algae harvesting needs. As a whole, the vessels and equipment are not suitable for small bodies of water such as rivers and lakes or small areas of algae harvesting.

[0003] For meandering rivers and lakes, researchers have conducted long-term monitoring of algae in the water. They found that algal changes are influenced by multiple factors, including sunlight, weather, water quality, and biological activity, making it impossible to summarize them using simple patterns. Therefore, site-specific control measures are necessary to achieve algae management. Existing algal research shows that when algae are present in water, they produce oxygen through photosynthesis. However, when algal coverage is excessive, water transparency decreases, leading to insufficient photosynthesis and a significant increase in oxygen consumption through respiration, causing hypoxia and resulting in black and smelly water. Therefore, researchers further monitored the relationship between algae and dissolved oxygen in river water. The monitoring results showed that the relationship between algal coverage and dissolved oxygen levels is not linear. Therefore, river maintenance personnel cannot rely on experience to predict how to remove algae and reoxygenate the water.

[0004] Existing methods for algae harvesting on water are either manual or mechanical. For small, winding waterways, where there are often blind spots, manual harvesting remains the primary method, offering flexibility and mobility but being time-consuming and labor-intensive. Mechanical equipment, typically used in large navigable waterways, is too large for winding, small channels. Current river and lake reoxygenation facilities are mostly located at fixed points with fixed aeration equipment. When dissolved oxygen levels are uneven in the water or in areas with particularly low dissolved oxygen levels, mobile reoxygenation is not feasible. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a flexible aquatic algae collection device that is suitable for small rivers and lakes.

[0006] The technical solution adopted by the present invention to solve its technical problem is: an aquatic algae collection device, including a hull and an energy storage component disposed on the hull. A capture component for obtaining algae from the water, a peeling component for detaching algae from the capture component, and a collection component for collecting algae are disposed at the forward end of the hull. The capture component includes a lifting assembly that can be raised and lowered in the vertical direction, a movable rod disposed on the lifting assembly, and a plurality of cleaners disposed on the movable rod. There is at least one capture component. At least one capture component is pivotally connected at one end to one side of the hull, and the other end is a free end. After the cleaners obtain algae, they rise with the lifting assembly to the peeling component, where the peeling component peels off the algae, which is then collected by the collection component.

[0007] More specifically, the capture assembly has three components: a first capture assembly, a second capture assembly, and a third capture assembly. The first capture assembly is located at the front of the hull. One end of the second capture assembly is pivotally connected to one side of the hull, and the other end of the second capture assembly is a free end. One end of the third capture assembly is pivotally connected to the other side of the hull, and the other end of the third capture assembly is a free end.

[0008] More specifically, a plurality of the cleaning devices are evenly distributed on the movable rod, and the cleaning devices are brushes that can rotate around the movable rod; all of the plurality of cleaning devices rotate in the forward direction, or all rotate in the reverse direction, or at least one rotates in the forward direction and at least one rotates in the reverse direction.

[0009] More specifically, the peeling assembly includes a fixing plate fixed to the hull and a plurality of spitting teeth disposed on the fixing plate. The cleaner cooperates with the spitting teeth to peel off the algae. The peeling assembly is inclined, with the spitting teeth facing outward.

[0010] More specifically, the collection component includes an inclined algae-draining net and a water collection tank located below the algae-draining net, with a drain hole provided on the water collection tank.

[0011] More specifically, the collection assembly includes a movable mesh belt assembly and a water collection tank disposed below the mesh belt assembly, with a drain hole provided on the water collection tank; a blocking element or a collection frame is provided at the lower end of the mesh belt assembly.

[0012] More specifically, the hull is equipped with a control component, a water reoxygenation component, and a detection component. The energy storage component supplies power to the control component, the water reoxygenation component, the detection component, and the capture component. The control component is used to receive data from each component and send control signals. The water reoxygenation component is located below the waterline of the hull and can penetrate into the water through several aeration hoses.

[0013] More specifically, the detection component includes a first detector for algae monitoring and a second detector for dissolved oxygen monitoring, both of which are capable of moving independently on the water surface.

[0014] More specifically, the first detector includes a first movable body, a sampling tube and a pressure pump disposed on the first movable body, wherein multiple sampling tubes are provided, and the pressure pump is connected to the sampling tubes through multiple pipes, and each pipe is provided with a solenoid valve.

[0015] More specifically, the second detector includes a second movable body, a clean water chamber, an equipment chamber, and a test chamber within the second movable body. A probe is installed in the test chamber, and a water inlet is provided on the test chamber. An automatically opening and closing sealing door is provided on the water inlet. A nozzle is installed on the test chamber and is connected to the clean water chamber. A booster pump is installed in the equipment chamber and is connected to the clean water chamber. A drain pipe is also installed in the test chamber and is connected to a drain pump, which is located inside the equipment chamber.

[0016] The beneficial effects of this invention are:

[0017] 1. The capture assembly consists of a movable rod and a steerable cleaner mounted on the rod. The capture assembly can be installed at the front of the hull or pivotally connected to one or both sides of the hull. When the capture assembly encloses a certain area with the hull, it helps to gather algae in front of the hull. It can be opened at different angles as needed to adapt to different widths of waterways and can also be used to collect algae from dead corners of the waterway. It is particularly suitable for smaller water areas and winding waterways. It is small in size, flexible, convenient, and highly maneuverable. When algae collection is not required, the capture assembly can be retracted to reduce running resistance.

[0018] 2. The detection component can be separated from the hull and operate independently, simultaneously realizing the functions of detecting water algae content, water oxygen content, and algae collection, saving time and improving efficiency; the detection component scans the river water area and divides the water surface into several areas, detecting the water conditions in different areas, which facilitates the hull to move to the corresponding area for subsequent algae collection and water oxygenation.

[0019] 3. The first detector detects the algae content in the water, and the second detector detects the oxygen content in the water. The detected data is compared with the baseline data for judgment, and the judgment result is fed back to the ship to enable the ship to accurately reach the river position where algae collection or water reoxygenation is required, so as to realize the operation of algae collection or water reoxygenation; when a certain position requires both algae collection and water reoxygenation at the same time, both can be carried out simultaneously.

[0020] 4. The combination of the capture component and the stripping component enables rapid collection of algae after harvesting. The cleaner in the capture component can rotate in either the forward or reverse direction. By changing the rotation direction, the algae can be stripped in conjunction with the stripping component, facilitating the rapid start of a new round of capture. The algae are conveyed to the blocking device or collection frame at the lower end of the algae collection device via the mesh belt assembly. Replacing the blocking device or collection frame with a new one allows for the transfer of algae. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0031] This invention provides a water algae collection device for small bodies of water and winding rivers. Its main purpose is to facilitate convenient and quick algae collection, and it is also flexible in its use. Figure 1 The water algae collection device shown includes a hull 1 and an energy storage component installed on the hull 1. At the forward end of the hull 1, there is a capture component 2 for capturing algae from the water, a peeling component 3 for removing algae from the capture component 2, and a collection component 4 for collecting the removed algae. When algae are found in a certain water area, the hull 1 moves to that water area and simultaneously puts the capture component 2 into the water. The movement of the hull 1 causes the algae to be located on the capture component 2. Then, the capture component 2 is driven to the peeling component 3. The peeling component 3 peels off the algae wrapped around the capture component 2. After peeling, the algae detaches from the peeling component 3 and enters the collection component 4 for collection.

[0032] Among them, such as Figure 2The capture assembly 2 shown includes a lifting group that can be raised and lowered in the height direction, a movable rod 21 disposed on the lifting group, and a plurality of cleaners 22 disposed on the movable rod 21. At least one capture assembly 2 can be disposed at the forward end of the hull 1 and on one side of the hull 1. At least one capture assembly 2 is pivotally connected at one end to one side of the hull 1, and the other end is a free end. The capture assembly 2 can rotate around the pivot axis, thereby realizing the opening and closing of the capture assembly 2. Further, a preferred technical solution is that the capture assembly 2 has three components, including a first capture assembly, a second capture assembly, and a third capture assembly. The first capture assembly is disposed at the front end of the hull 1. One end of the second capture assembly is pivotally connected to one side of the hull 1, and the other end of the second capture assembly is a free end. One end of the third capture assembly is pivotally connected to the other side of the hull 1, and the other end of the third capture assembly is a free end. Through the arrangement of the second and third capture assemblies, a long distance can be extended to both sides of the hull 1, and the capture range can be adjusted, which can be at least three times the width of the hull 1.

[0033] The lifting assembly can be a gear and rack mechanism, a belt lifting mechanism, or a chain lifting mechanism. Its main purpose is to lift the capture assembly located in the water body to the side of the stripping assembly on the hull.

[0034] The movable rod 21 can rotate either around its pivot axis or around its axis. The cleaner 22 is fixed to the movable rod 21 and can rotate with the movable rod 21. Several cleaners 22 are evenly distributed on the movable rod 21. The cleaner 22 is a brush. The cleaner 22 can move in various ways, such as all rotating in the forward direction, all rotating in the reverse direction, or at least one rotating in the forward direction and at least one rotating in the reverse direction. Furthermore, the rotation direction of several cleaners 22 is such that the rotation direction of the odd number of cleaners 22 is opposite to that of the even number of cleaners 22. By having two adjacent cleaners 22 rotate in different directions, the cleaning of algae can be improved. When used in conjunction with the peeling component 3, it can be easily detached.

[0035] like Figure 2 The peeling assembly 3 shown includes a fixing plate 31 fixed to the hull 1 and a plurality of spitting teeth 32 disposed on the fixing plate 31. The spitting teeth 32 are tooth-shaped protrusions from the fixing plate 31, and there is a tooth groove 33 between adjacent spitting teeth 32. The cleaner 22 can be inserted into the tooth groove 33. Each cleaner 22 corresponds to one tooth groove 33. The spitting teeth 32 are located between two cleaners 22. The design of the spitting teeth 32 can scrape the algae wrapped around the cleaner 22 onto the spitting teeth 32. The fixing plate 31 and the spitting teeth 32 are integrally formed and inclined. The spitting teeth 32 face outward, that is, the high end is close to the cleaner 22 and the low end is close to the collection assembly 4. The inclined arrangement facilitates the entry of the peeled algae into the collection assembly 4.

[0036] like Figure 3 The collection component 4 shown includes an inclined algae-draining net 41 and a water collection tank 42 located below the algae-draining net 41. A drain hole 43 is provided on the water collection tank 42. The high end of the algae-draining net 41 is close to the algae-draining teeth 32, and the low end is inclined towards the hull 1. Algae can slide downward with the inclined surface, and water enters the water collection tank 42 and can be discharged through the drain hole 43.

[0037] The algae-draining net 41 can be designed as a movable structure, which can be a movable mesh belt assembly. The water collection tank 42 is located below the mesh belt assembly to collect water. The mesh belt assembly includes two drive rollers and a mesh belt mounted on the two drive rollers. Driving one of the drive rollers to rotate will cause the mesh belt to rotate, which can transfer the algae peeled off by the algae-draining teeth 32 from the high end to the low end, so that subsequent algae can enter the algae-draining net 41. Furthermore, in order to ensure that the mesh belt assembly moves when working and does not move when not working, pressure sensors are installed below the two ends of the drive roller near the high end. When algae fall onto the mesh belt, The pressure is transmitted downwards through the drive rollers. At this time, the pressure sensor detects the pressure change, sends a control signal, and drives the mesh belt to move. To prevent false starts, a corresponding pressure threshold can be set. When the pressure reaches the corresponding threshold, the mesh belt is controlled to move. The pressure sensor here can also be designed as other detection sensors, such as a displacement sensor. The corresponding drive roller can move up and down and be reset by a spring. When the displacement sensor detects a corresponding displacement of the drive roller, it indicates that algae have entered the mesh belt, and the mesh belt is then controlled to move.

[0038] Furthermore, to prevent algae from entering the hull 1 from the algae-draining net 41, a blocking element 44 is provided at the lower end of the algae-draining net 41; or, a collection frame is provided at the lower end of the algae-draining net 41, and a positioning groove is provided on the corresponding hull 1. The collection frame is inserted into the positioning groove to ensure that the collection frame will not shake during the movement of the hull 1 on the water surface, so that the algae on the net belt is transported from the high end to the low end and enters the collection frame. The positioning groove also has the function of collecting water. A water outlet is opened on one side of the positioning groove, and the water outlet discharges the water filtered by the collection frame into the water body; when the collection frame is full of algae, the hull 1 is moved to the side and the collection frame is manually removed and an empty collection frame is placed to continue collecting algae; a handle can be provided on the collection frame for easy manual handling.

[0039] To facilitate the search for algae and the detection of water quality, a control component, a water reoxygenation component, and a detection component are installed on the hull 1. The control component is used to receive data signals from each component, process them, and then issue control signals. The control component controls the movement of the hull 1, the movement of the capture component 2, the reoxygenation of the water component, and the driving of the detection component to a designated location for water detection.

[0040] The energy storage component is used to provide power for the hull 1 to move on the water surface and to supply power to the energy-consuming equipment in the hull 1. The energy storage component includes a battery and a solar panel. The battery can be charged directly by mains power or by the solar panel. The energy storage component may also include wind power charging equipment, etc.

[0041] like Figure 4 The water reoxygenation component shown is located below the waterline 8 of the hull 1. The water reoxygenation component includes a reoxygenation pump and several aeration hoses 7 extending into the water. The aeration hoses 7 adopt a disc structure and are connected to the reoxygenation pump. Using aeration hoses 7 can avoid the entanglement of aquatic plants in the water and the impact of hard materials in the water.

[0042] like Figure 1 The detection assembly shown includes a first detector 5 for algae detection and a second detector 6 for dissolved oxygen monitoring. Both the first detector 5 and the second detector 6 can move independently on the water surface.

[0043] like Figure 5 The first detector 5 shown includes a first mobile body 51, a sampling tube 52 and a pressure pump 53 disposed on the first mobile body 51. Multiple sampling tubes 52 are provided, and the pressure pump 53 is connected to the sampling tubes 52 through multiple pipes. Each pipe is equipped with a solenoid valve. At the same time, a scanning device is provided on the first mobile body 51. The scanning device can scan the water surface area or manually input the water surface area, and can perform self-positioning and plan its travel route.

[0044] First, the first detector 5 scans the water body and divides the water surface into several areas. The first detector 5 is then controlled to collect water samples from each area. Each sampling tube 52 can collect water samples from one area, and multiple sampling tubes 52 can collect water samples from different areas. Afterward, the system returns to the hull 1 to read the data. The data is compared with the baseline data in the control component to determine the range of algae and is fed back to the control component. Based on the detection results, the control component moves the hull 1 to the area where the data exceeds the standard to collect algae. The sampling time of the first detector 5 is controlled within 10 minutes. After returning to the hull 1, the sampling tubes 52 are left to stand under sunlight or fluorescent light for 60 minutes. Each sampling tube 52 is then scanned and the bubble density is determined. When the bubble density is greater than the standard value, it indicates that the algae in the area corresponding to that sampling tube 52 exceeds the standard. The standard value is the relationship between bubble density and chlorophyll A measurement value, which is calibrated in advance by the laboratory. The control component then controls the hull 1 to move to the corresponding water area to collect algae.

[0045] like Figure 6The second detector 6 shown includes a second movable body 61, a water chamber 62, an equipment chamber 63, and a test chamber 64 within the second movable body 61. A probe 65 is installed in the test chamber 64. A water inlet is provided on the test chamber 64, and an automatically opening and closing sealing door 66 is provided on the water inlet. A vent is provided on the test chamber 64; when venting is not required, it can be automatically sealed by a sealing cover, or a pressure valve can be provided on it, automatically opening when the internal air pressure reaches a certain threshold. A nozzle 67 is installed on the test chamber 64. 67 is connected to the clear water chamber 62. A booster pump 68 is installed in the equipment chamber 63 and connected to the clear water chamber 62. A drain pipe is also installed in the test chamber 64, and a drain pump 69 is connected to the drain pipe. The drain pump 69 is installed in the equipment chamber 63 and draws out the liquid in the test chamber 64 through the drain pipe and discharges it to the second detector 6. A filter screen can also be installed on the water inlet. At the same time, a scanning device is also installed on the second moving body 61. The scanning device can scan the water surface area or manually input the water surface area, and can perform self-positioning and plan its movement route.

[0046] The second detector 6 scans the water body and divides the water surface into several areas. The second detector 6 moves to each area to detect the water quality. At this time, the sealing door 66 opens and the probe 65 comes into contact with the water. The detected data is compared with the reference data in the second detector 6. The detection time of the second detector 6 is controlled within 10 minutes. After the detection is completed, the second detector 6 returns to the hull and transmits the data to the control component. The control component then controls the hull 1 to move to a position below the standard to perform aeration.

[0047] During use, the probe 65 may become contaminated by water, causing inaccurate detection. Therefore, the probe 65 needs to be cleaned. When abnormal data is detected, the second detector 6 rises to the water surface, opens the vent and closes the sealing door 66. The water in the test chamber 64 is emptied by the drain pump 69. Then, the nozzle 67 is opened and the pressure is increased in the clean water chamber 62 by the booster pump 68. The clean water in the clean water chamber 62 is sprayed onto the probe 65 through the nozzle 67 to clean the probe 65. The water is drained again by the drain pump 69. The water discharged here can be directly discharged into the water body, or a wastewater chamber can be designed to store the wastewater after cleaning.

[0048] When an abnormality is detected in the water quality of a certain area, it is necessary to clean the area and measure it again. If multiple measurements show an abnormality, it indicates that the water quality at this location is abnormal, and the vessel 1 needs to sail to this location to perform a reoxygenation operation. After the reoxygenation operation has been running for a specified time, the second detector 6 will perform another test. If the water quality still does not meet the standard range, the reoxygenation process will continue. If the water quality meets the standard range, the vessel 1 will sail to the next area to perform a reoxygenation operation. If the test data is much larger than the detection range, and remains much larger than the detection range after cleaning, the second detector 6 needs to return to the vessel 1 for deep cleaning, which can be done manually.

[0049] The hull 1, the first detector 5, and the second detector 6 can operate at different times. For example, after the first detector 5 and the second detector 6 have completed the detection of water quality and algae concentration, they can wait for the data to be available before carrying out algae collection and reoxygenation operations in the water area where the operation is needed. The route can be planned based on the data results to save travel distance. Alternatively, they can operate simultaneously. Since the first detector 5 requires time to detect, while the second detector 6 can detect data in a timely manner, the route can be planned first based on the results of the second detector 6 to carry out the reoxygenation operation. After the results of the first detector 5 are available, the route can be planned based on the results of the first detector 5 to carry out the algae collection operation. When neither the first detector 5 nor the second detector 6 provides any feedback data, the corresponding task can be carried out by manual judgment and route planning.

[0050] In addition to the operation of the ship through the program linkage formed by the detection components and the hull, the ship can also be navigated manually to meet the needs of temporary algae collection and water reoxygenation.

[0051] In summary, the capture assembly consists of a movable rod and a steerable cleaner mounted on it. The capture assembly is pivotally connected to one or both sides of the hull. When the capture assembly encloses a certain area with the hull, it helps to gather algae in front of the hull. It can open at different angles as needed to adapt to rivers of varying widths and can also collect algae from dead corners of the river. It is particularly suitable for smaller water areas and winding rivers. Its compact size, flexibility, and high maneuverability make it ideal. When algae collection is not required, the capture assembly can be retracted to reduce drag. The detection assembly can be separated from the hull and operate independently, simultaneously detecting algae content, oxygen content, and collecting algae, saving time and improving efficiency. The detection assembly scans the river and divides the water surface into several areas, detecting the water conditions in different areas. The vessel navigates to the designated area for subsequent algae collection and water reoxygenation. A first detector measures the algae content, and a second detector measures the oxygen content. The detected data is compared to baseline data, and the results are fed back to the vessel, enabling it to precisely reach the desired location for algae collection or reoxygenation. Simultaneous collection and reoxygenation can be performed at any given location. The combination of a capture component and a stripping component allows for rapid collection of harvested algae. The cleaner in the capture component can rotate in either direction, allowing for algae stripping in conjunction with the stripping component, facilitating a quick start to the next round of capture. The algae are conveyed to a lower barrier or collection frame via a mesh belt within the collection device. Replacing the barrier or collection frame with a new one allows for further transport of the algae.

[0052] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
