Description

Technical Field

[0001] This invention relates to the field of water environmental protection and management technology, specifically to a drive device and drive method for a water-control unmanned ecological vessel. Background Technology

[0002] The algae-control unmanned ecological vessel is an advanced device specifically designed for the management and removal of algae in water bodies. Due to factors such as eutrophication and environmental pollution, algae proliferate excessively in water bodies, disrupting the ecological balance and severely impacting water quality and the surrounding landscape. To address these shortcomings, the algae-control unmanned ecological vessel has been developed.

[0003] However, despite the numerous advantages of unmanned ecological vessels for algae control, they still face some challenges in practical applications. For example, traditional algae control vessels typically use physical water pressure to break down the mechanism of cyanobacteria growth and reproduction from within the cells. Utilizing the incompressibility of water, a pressure medium is injected into a sealed water container filled with cyanobacteria, rapidly pressurizing it before discharge. However, the discharged pressurized water is often not utilized effectively; indiscriminate discharge increases the vessel's drag and results in excessive energy consumption, making it difficult to achieve long-term, high-efficiency algae removal operations. Therefore, a propulsion device and method for unmanned ecological vessels for algae control are proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a driving device and driving method for an unmanned ecological vessel for algae control, which has advantages such as higher energy utilization and greater energy saving. It solves the problem that traditional algae control vessels often do not make reasonable use of the pressurized water discharged, and that the arbitrary discharge of pressurized water will lead to increased ship drag, excessive energy consumption, and difficulty in achieving long-term, high-efficiency algae cleaning operations.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goals of higher energy utilization and greater energy efficiency, the present invention provides the following technical solution:

[0008] This invention provides a drive device for an unmanned ecological boat for controlling algae growth, including a hull. A control center is provided on the top of the hull. The control center is electrically connected to an algae absorption system located at the front of the hull and a separation system inside the hull. One side of the separation system is connected to the algae absorption system, and the other side of the separation system is connected to at least two sets of algae suppression systems controlled by the control center. Each set of algae suppression systems includes two algae suppression components that are symmetrical about the central axis of the hull and are located at the stern of the hull.

[0009] Each of the algae-controlling components includes a pressure tube, one side of which is connected to the separation system, and the other side has a first propeller inside. The middle of the pressure tube is used for pressurization and algae control. The first propeller and part of the pressure tube are located on the outer side of the stern of the ship.

[0010] The control center is also electrically connected to the second propeller at the front of the bottom of the hull and several monitoring cameras around the hull.

[0011] A preferred embodiment of the present invention is that each of the algae-pressing components further includes a first flow regulator and a second flow regulator disposed inside the pressure tube, and the pressure tube is also provided with a first air valve and a pressure gauge.

[0012] A preferred embodiment of the present invention is that a water storage system controlled by a central control unit is also provided at the bottom of the hull. The water storage system includes a water tank, a water pump, and a suction pipe. The water pump is used to pump water from the water tank to control the draft of the hull.

[0013] A preferred embodiment of the present invention is that the algae suction system includes an algae suction pipe and an algae suction pump on the algae suction pipe. The algae suction pipe is provided with an algae suction port at the front of the hull and a liquid outlet on the other side.

[0014] A preferred embodiment of the present invention is that the separation system includes a separation box, a first alarm device and a second alarm device are provided inside the separation box, at least one exhaust pipe is provided at the upper end of the separation box, a second air valve is provided in each exhaust pipe, and a stirring device is also provided inside the separation box for stirring the absorbed algae water.

[0015] Another aspect of the present invention provides a driving method for an unmanned ecological vessel for controlling algae, which is applied to the driving device of an unmanned ecological vessel for controlling algae as described in any of the above aspects. The negative pressure generated when the first thruster rotates discharges the pressurized and dead cyanobacteria water in the pressure pipe, thereby generating forward thrust for the hull.

[0016] A preferred embodiment of the present invention is that when the first thruster discharges the pressurized and dead cyanobacteria water from the pressure pipe, the unpressurized cyanobacteria water in the separation box is further replenished into the pressure pipe, thereby providing uninterrupted power to the hull.

[0017] A preferred technical solution of the present invention is that at least two algae-suppressing systems are provided, ensuring that while one algae-suppressing system is pressurizing and controlling algae, the other algae-suppressing system drives the hull.

[0018] The preferred technical solution of the present invention is that by adjusting the different rotation speeds of multiple first thrusters, the displacement on both sides of the hull is different, thereby generating different power to achieve the steering of the hull.

[0019] The preferred technical solution of the present invention is that a second thruster is provided to work together with the first thruster to drive the hull, a monitoring camera monitors the speed of the hull, and a control center regulates the first and second thrusters to achieve overall hull driving.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a driving device and driving method for a controlled-water unmanned ecological vessel, which has the following beneficial effects:

[0022] The drive device and method of this algae-controlling unmanned ecological vessel utilizes at least two algae-pressurizing systems located at the stern. The rotation of the first thruster creates negative pressure, facilitating the replacement of the water pressured in the pressurized pipe for subsequent algae suppression. Simultaneously, the discharged water can be used to propel the vessel. This efficient storage and utilization of pressurized algae-laden water before effective discharge reduces resistance during vessel movement. Furthermore, the discharge of pressurized water provides propulsion, resulting in significantly lower energy consumption, longer operating time, and greater energy efficiency and environmental friendliness compared to traditional algae-controlling vessels.

[0037] Example 1

[0038] Please see Figure 1-10A drive device for an unmanned ecological boat for controlling algae growth includes a hull 1. A control center 2 is provided on the top of the hull 1. The control center 2 is electrically connected to an algae absorption system 3 located at the front of the hull 1 and a separation system 4 inside the hull 1. One side of the separation system 4 is connected to the algae absorption system 3, and the other side of the separation system 4 is connected to at least two sets of algae suppression systems 5 controlled by the control center 2. Each set of algae suppression systems 5 includes two algae suppression components 51 that are symmetrical about the central axis of the hull 1 and are located at the stern of the hull 1.

[0039] Each algae-suppressing assembly 51 includes a pressure pipe 513. One side of the pressure pipe 513 is connected to the separation system 4, and the other side is equipped with a first thruster 511. The middle part of the pressure pipe 513 is used for pressurization and algae control. The first thruster 511 and part of the pressure pipe 513 are located on the outer side of the stern of the hull 1.

[0040] The control center 2 is also electrically connected to the second thruster 6 at the front bottom of the hull 1 and several monitoring cameras 8 around the hull 1.

[0041] It should be noted that the algae-collecting system 3 is used to collect blue-green algae on the water surface and should be installed at the water surface. The first propeller 511 is used to discharge the pressurized water, thereby giving the hull 1 the power to drive forward. The first propeller 511 should be installed at the bottom of the water. Therefore, it should be ensured that there is a certain horizontal height difference between the first propeller 511 and the algae-collecting system 3, and the first propeller 511 is located below the algae-collecting system 3.

[0042] In this embodiment, each algae-pressing assembly 51 also includes a first flow regulator 514 and a second flow regulator 515 disposed inside the pressure tube 513, and a first air valve 516 and a pressure gauge 512 are also disposed on the pressure tube 513.

[0043] It should be noted that when pressurizing algae for the first time in pressure pipe 513, the second flow regulator 515 should be closed, and the first flow regulator 514 and the first air valve 516 should be opened. When the cyanobacteria-infused water in the separation tank 42 enters the pressure pipe 513, the first air valve 516 should be used to continuously vent air, so that the pressure pipe 513 is filled with cyanobacteria-infused water. Then, the first flow regulator 514 and the first air valve 516 should be closed to pressurize the cyanobacteria-infused water in pressure pipe 513. After pressurization, the water is stored in pressure pipe 513 and can be released at any time by opening the first flow regulator 514 and the second flow regulator 515.

[0044] In this embodiment, a water storage system 7 controlled by the control center 2 is also provided at the bottom of the hull 1. The water storage system 7 includes a water tank 71, a water pump 73 and a suction pipe 72. The water inside the water tank 71 can be pumped by the water pump 73, thereby realizing the control of the draft of the hull 1.

[0045] It should be noted that the monitoring camera 8 monitors the draft of the ship 1 and uploads the data to the control center 2 in real time. The control center 2 controls the water pump 73, which pumps water from the water storage tank 71 through the suction pipe 72, thereby controlling the draft of the ship 1.

[0046] In this embodiment, the algae suction system 3 includes an algae suction pipe 32 and an algae suction pump 33 on the algae suction pipe 32. The algae suction pipe 32 is provided with an algae suction port 31 at the front end of the hull 1, and a liquid outlet 34 is provided on the other side of the pipe.

[0047] It should be noted that when the algae pump 33 starts working, the water containing cyanobacteria and air enters the algae suction pipe 32 through the algae suction port 31, and then flows into the separation system 4 through the liquid outlet 34. The liquid outlet 34 is connected to the upper part of the separation tank 42. A filter screen that allows cyanobacteria to pass through can be installed at the algae suction port 31. Its main purpose is to filter floating objects and large impurities in the water.

[0048] In this embodiment, the separation system 4 includes a separation box 42, which is equipped with a first alarm device 44 and a second alarm device 45. At least one exhaust pipe 41 is provided at the upper end of the separation box 42, and a second air valve is provided in each exhaust pipe 41. The separation box 42 is also equipped with a stirring device 43 for stirring the absorbed algae water.

[0049] It should be noted that the first alarm device 44 is the highest water level alarm. When the water level inside the separation tank 42 is at the upper end of the first alarm, the alarm sends an electrical signal to the control center 2. The control center 2 then regulates each system to lower the water level and ensure stable operation between the systems. At the same time, the second alarm device 45 is the lowest water level alarm. When the water level inside the separation tank 42 is at the lower end of the second alarm, the control center 2 also adjusts and balances each system.

[0050] It should be further explained that the stirring device 43 is used to stir the cyanobacteria inside the separation box 42 to ensure that the cyanobacteria die more completely when pressurized later, and at the same time reduce the occurrence of jamming caused by discharge through the first thruster 511.

[0051] It should also be further explained that the second air valve is used to maintain the pressure balance inside the separation tank 42. At the same time, when the blue-green algae is sucked in, since the blue-green algae float on the water surface, there will inevitably be some air present during the suck-in. The sucked-in air is discharged through the exhaust pipe 41 to avoid affecting the subsequent pressurization and algae control and drainage drive.

[0052] In this embodiment, the monitoring camera 8 is used to detect the draft of the ship 1 and the speed of the ship 1, and sends electrical signals to the control center 2 in real time.

[0053] It should be noted that when the device starts working, the algae suction port 31 must be located exactly at the water surface; otherwise, the driving method cannot be carried out. The monitoring camera 8 is linked with various systems to jointly realize the overall algae suction and driving operation of the device.

[0054] Meanwhile, two observation ports 9 are also opened at the upper end of the stern of the hull 1. The observation ports 9 are located directly above the pressure pipe 513. Each observation port 9 is rotatably connected to a cover plate 91, and each cover plate 91 has a window 911.

[0055] It should be noted that the observation port 9 is more convenient for maintenance and repair, and it facilitates the observation of pressure gauge 512 and the maintenance of pressure tube 513.

[0056] Example 2

[0057] A driving method for an unmanned ecological vessel for controlling algae is provided, which drives the driving device of an unmanned ecological vessel for controlling algae in the above embodiment 1. The negative pressure generated when the first thruster 511 rotates discharges the pressurized and dead cyanobacteria water in the pressure pipe 513, so that the hull 1 generates forward thrust.

[0058] It should be noted that, based on the principle of mutual action, the pressurized cyanobacteria water is stored in the pressure pipe 513 and released when needed to drive the hull 1. The specific number and size of the pressure pipes 513 should be determined according to the actual displacement of the hull 1 to ensure that the pressurized water discharged is sufficient to drive the hull 1.

[0059] In this embodiment, when the first thruster 511 discharges the pressurized and dead cyanobacteria water in the pressure pipe 513, the unpressurized cyanobacteria water in the separation box 42 will be further replenished into the pressure pipe 513, thereby providing uninterrupted power to the hull 1.

[0060] In this embodiment, at least two sets of algae-suppressing systems 5 are provided to ensure that when one algae-suppressing system 5 is pressurizing and controlling algae, the other set of algae-suppressing systems 5 drives the hull 1.

[0061] It should be noted that the pressurization time for the algae control vessel is very short. The installation of at least two algae control systems 5 ensures that the hull 1 can be driven by the rotation of the first propeller 511 at all times. The drainage drive is carried out simultaneously, which is more energy-efficient.

[0062] In this embodiment, by adjusting the different rotation speeds of multiple first thrusters 511, the displacement on both sides of the hull 1 is different, thereby generating different power to achieve steering of the hull 1.

[0063] It should be noted that by controlling the central hub 2 to adjust the first thruster 511 in the pressurized pipe at different positions, a displacement difference is generated on both sides of the stern of the hull 1, thereby enabling the hull 1 to turn and making the drive more flexible.

[0064] In this embodiment, the second thruster 6 is used to drive the hull 1 together with the first thruster 511. The monitoring camera 8 monitors the speed of the hull 1, and the control center 2 controls the first thruster 511 and the second thruster 6 to achieve the overall driving of the hull 1.

[0065] It should be noted that the vessel 1 is not very stable at the beginning of startup and at the end of shutdown. At startup, the algae suction system 3 has not yet started working, so there is not enough water in the pressure pipe 513 to drive the vessel 1. At this time, the control center 2 controls the second propeller 6 to drive the vessel 1. When there is enough water in the pressure pipe 513 for subsequent circulation, the control center 2 gradually weakens and shuts off the second propeller 6. At this time, the above-mentioned drainage method is used to drive the vessel 1. Or, in case of an emergency, such as the pressure pipe 513 being damaged, the control center 2 can also control the second propeller 6 to turn the vessel back and finally request manual intervention to repair the vessel.

[0066] In summary, the driving device and method of this algae-controlling unmanned ecological vessel utilize at least two sets of algae-pressurizing systems 5 located at the stern of the hull 1. The rotation of the first thruster 511 creates negative pressure at the first thruster 511, facilitating the replacement of the water in the pressure pipe 513 after algae pressurization, thus enabling the next algae pressurization cycle. Simultaneously, the discharged water can be used to drive the hull 1. This efficient storage and utilization of pressurized algae-inducing water before effective discharge reduces the resistance to the hull 1 during discharge. Furthermore, the discharge of pressurized water provides power for the hull 1's movement. Compared to traditional algae-controlling vessels, this method significantly reduces energy consumption, extends operating time, and is more energy-efficient and environmentally friendly.
