Description

Technical Field

[0001] The present invention relates to the field of ecological environment management, and in particular to a push-flow type mechanically pressurized cyanobacteria control vessel. Background Art

[0002] Algal blooms are a major environmental problem facing water bodies worldwide, particularly in eutrophic lakes. Excessive growth of cyanobacteria can lead to deteriorating water quality, disrupting aquatic ecosystems, and threatening aquatic ecological safety with cyanobacterial toxins. Due to their short growth cycles and the presence of pseudo-cavities, cyanobacteria easily develop growth advantages. Traditional methods for controlling algal blooms, such as chemical algaecides, physical salvage, and biological agents, all have significant shortcomings, including secondary pollution, low treatment efficiency, poor algae control, and high costs.

[0003] Because cyanobacteria possess pseudocavities, they can rise or fall in water by adjusting their buoyancy, thereby gaining a competitive advantage. These pseudocavities are susceptible to rupture under certain pressure conditions, causing them to lose buoyancy and sink to the bottom of the water, where they cease photosynthesis and naturally die. Existing pressurized algae control devices include two types: fixed-type caissons, which can achieve large-scale algae control but are immobile, lack maneuverability, and consume high energy. Another type, algae control vessels, typically process hundreds of tons per hour and utilize high-pressure pumps to provide pressure and sample the algae solution, resulting in high energy consumption.

[0004] Therefore, it is particularly important to develop an efficient and energy-saving method and device for controlling cyanobacteria. Summary of the Invention

[0005] The purpose of the present invention is to provide a plug-flow mechanically pressurized cyanobacteria control vessel, which utilizes the principle of pressurized algae control and achieves the purpose of controlling cyanobacteria outbreaks with high efficiency and low energy consumption through plug-flow design and mechanical pressurization device design. The device is mainly used for emergency control of cyanobacteria blooms.

[0006] To achieve the above object, the present invention provides the following solutions:

[0007] The present invention provides a push-flow mechanically pressurized cyanobacteria control vessel, comprising:

[0008] a hull, wherein the upper surface of the hull is provided with a deck;

[0009] an algae collecting head, the algae collecting head being swingably connected to the front end of the hull;

[0010] Buoyancy chambers are arranged at the front and rear ends of the bottom of the hull;

[0011] A water collection tank connected to the rear end of the algae collecting head;

[0012] A pressure treatment chamber is provided in the middle of the hull and is connected to the water collection tank, and a discharge outlet is provided at the bottom of the pressure treatment chamber;

[0013] A pressurizing component is disposed in the pressurizing processing chamber.

[0014] Preferably, a power device and a generator are provided at the rear of the hull.

[0015] Preferably, a cab is provided at the front of the hull.

[0016] Preferably, the side edges of the hull are provided with guardrails.

[0017] Preferably, the algae collecting head has a dustpan-like structure when unfolded.

[0018] Preferably, the algae collecting head includes a support rod, which is hinged to both sides of the head of the hull and connected to the electric hydraulic support rod. A coil is fixed between the support rods on both sides, and the coil is connected to the hull through a hinged retractable soft connection.

[0019] Preferably, a water collection pool algae inlet is provided at the front end of the water collection pool, and the water collection pool algae inlet is connected to the algae collection head; a pressurized treatment tank algae inlet is provided at the front end of the pressurized treatment tank, and the pressurized treatment tank algae inlet is connected to the water collection pool, and a valve opening and closing machine is provided at the pressurized treatment tank algae inlet.

[0020] Preferably, the number of the pressurized treatment chambers is greater than or equal to 2, and they are arranged side by side in the middle of the hull.

[0021] Preferably, horizontal partitions are staggered in the pressure treatment chamber, and the spacing between the partitions is 0.2-0.5m; a flow pusher is provided at the bottom of the pressure treatment chamber.

[0022] Preferably, the pressurizing assembly includes a cylinder body, the bottom of which is connected to the pressurizing treatment chamber, a piston seal is movably fitted in the cylinder body, the top of the piston seal is hinged to one end of a control rod through a connecting rod, the middle of the control rod is hinged to a column, the other end of the control rod is hinged to an electric push rod, and a pressure gauge is provided in the pressurizing treatment chamber.

[0023] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0024] (1) The pressurized treatment chamber adopts a layered design. The cyanobacteria are pushed into the pressurized treatment chamber and the pressurized sample is discharged at the same time as the sample is injected. No separate power equipment is required, which effectively reduces energy consumption.

[0025] (2) Through the design of the inlet and outlet, the thrust generated by the water inrush from the ship and the power of the low-power flow propeller are used to realize the injection and discharge of samples. No water pump is required to lift the sample, and the system operates with micro-power. This design can reduce the energy consumption of injection and discharge of samples to about 10% of the existing equipment.

[0026] (3) The cylinder of the pressurizing component is connected to the pressurizing treatment chamber. After the injection is completed, the cylinder and the pressurizing treatment chamber are filled with algae liquid. Due to the poor compressibility of water, the piston seal only needs to move downward a small distance to make the working pressure in the pressurizing treatment chamber reach 0.7Mpa. The pressurizing component uses the lever principle, and the up and down movement of the electric push rod drives the up and down movement of the piston seal to achieve pressurization of the pressurizing treatment chamber. This design requires less energy than directly using the electric push rod for pressurization or using a high-pressure water pump / air pump for pressurization (the pressurization method of the existing pressurized algae control ship), which is 5-10% of its energy consumption, with good energy saving effect and high treatment efficiency.

[0027] (4) Since cyanobacteria with ruptured pseudovacuoles are easy to recover under photosynthesis, the discharge outlet of the present application is designed to be located at the bottom of the hull, so that the discharge outlet can be located 1m below the water surface when the algae control boat is working normally, which is conducive to assisting the cyanobacteria with ruptured pseudovacuoles to continue to sink to the bottom of the water, and can effectively avoid the pressurized cyanobacteria from being flipped out of the water due to the disturbance of the hull movement and obtaining conditions for self-recovery, thereby further improving the algae control effect;

[0028] (5) In the early stage of algal bloom, algae only form a thin layer of algal bloom on the surface of the water body. When the algal bloom is serious, it can gather in the 0-20cm water layer or even the 0-50cm water layer. Based on this characteristic, the present application sets a dustpan-shaped algae collection head, and the depth of the algae collection head in the water layer can be freely adjusted so that it can collect algae liquid in any water layer of 0-50cm, such as 0-5cm water layer, 0-10cm water layer, etc., to carry out targeted collection of high-concentration algae liquid, thereby improving the collection and treatment efficiency of cyanobacteria;

[0029] (6) Two or more pressurized treatment chambers can be set up in parallel as needed to ensure the continuous operation of the algae control process;

[0030] (7) The present invention provides a push-flow mechanical pressurized cyanobacteria control ship. The push-flow mechanical pressurized cyanobacteria control ship has its own power and can be flexibly moved to the water area to be treated. Its maneuverability is excellent. It uses the lever principle and electric push rod to pressurize, which has low treatment energy consumption and faster pressurization speed than using air compressors, water pumps, etc. to directly pressurize the water body. Through the combined design of a dustpan-shaped algae collection head, an algae inlet position, and a pressurized treatment chamber layer, the ship's propulsion power and a flow pusher are used to achieve the entry and discharge of high-algae water, which greatly reduces the operating energy consumption compared to using a water pump for sampling. It can be applied to the prevention and control of cyanobacteria in lakes, reservoirs, water sources, landscape water bodies and other water areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] As an embodiment, the algae collecting head 2 has a dustpan-like structure after being unfolded, which can effectively increase the collecting area and thus improve the collecting efficiency.

[0058] As an embodiment, the algae collection head 2 includes a support rod 21, which is hinged on both sides of the head of the hull 1 and connected to the electric hydraulic support rod 22. The electric hydraulic support rod 22 can adjust the swing of the support rod 21, and then adjust the water immersion depth to ensure a good collection effect; a roll 23 is fixed between the support rods 21 on both sides, and its material is polyethylene polypropylene waterproof roll. The roll 23 is connected to the hull 1 through a hinged retractable soft connector 24. The hinged retractable soft connector 24 is made of polyethylene and can be stretched, contracted, and folded in any direction.

[0059] As an embodiment, a water collection pool algae inlet 41 is provided at the front end of the water collection pool 4, and the water collection pool algae inlet 41 is connected to the algae collection head 2; an algae inlet 51 is provided at the front end of the pressurized treatment chamber 5, and the size is generally selected between 500×500mm-1000×500mm, the pressurized treatment chamber algae inlet 51 is connected to the water collection pool 4, and a valve opening and closing machine 52 is provided at the pressurized treatment chamber algae inlet 51.

[0060] As an embodiment, the number of the pressurized treatment chambers 5 is greater than or equal to 2, and they are arranged side by side in the middle of the hull 1.

[0061] As an embodiment, a plurality of horizontal partitions 54 are staggered in the pressurized treatment chamber 5, and the spacing between the partitions 54 is 0.2-0.5m, ensuring that the internal water flows in an S-shape and is discharged from the pressurized treatment chamber from top to bottom in sequence; a flow pusher 53 is provided at the bottom of the pressurized treatment chamber 5 to ensure the flow direction of the water.

[0062] As an embodiment, the pressurizing assembly 7 includes a cylinder body 71, the bottom of the cylinder body 71 is connected to the pressurizing treatment chamber 5, and a piston seal 72 is movably fitted in the cylinder body 71. The top of the piston seal 72 is hinged to one end of a control rod 74 through a connecting rod 73, the middle of the control rod 74 is hinged to a column 75, and the other end of the control rod 74 is hinged to an electric push rod 76. A pressure gauge 77 is provided in the pressurizing treatment chamber 5. By utilizing the principle of leverage, the up and down movement of the electric push rod drives the up and down movement of the piston seal, thereby realizing pressurization of the pressurizing treatment chamber.

[0063] The present invention provides a push-flow mechanical pressurized cyanobacteria control ship, and its use method and working principle are as follows: First, when the cyanobacteria control ship is launched for the first time, it is necessary to fill the pressurized treatment tank with water through a water pump so that the hull reaches the draft depth of normal working state, that is, the upper edge of the algae inlet is about 0-10cm below the water surface. The second step is to start the power equipment and the generator, and adjust the depth of the algae collection head immersed in the water layer according to the water layer where the cyanobacteria gather on the surface of the water body through the electric hydraulic rod control to ensure the targeted collection of high-concentration algae liquid; the third step is to control the algae inlet and outlet of the No. 1 pressurized treatment tank to open and the algae inlet of the other pressurized treatment tanks to close, start the flow pusher, and start the hull. The thrust generated when the hull moves forward and the power of the flow pusher located in the pressurized treatment tank are used to push the algae-rich water into the algae collection head and enter the water collection tank through the algae inlet of the water collection tank. When the No. 1 pressurized treatment tank is full of algae-rich water, the valve opening and closing machine controls the closing of the No. 1 pressurized treatment tank. The algae inlet and outlet of the treatment chamber are opened, and the algae inlet and outlet of the pressurized treatment chamber No. 2 are opened at the same time. The hull continues to move forward and repeats the process of algae entering the pressurized treatment chamber No. 1. At this time, the pressurized treatment chamber No. 1 is full of algae-rich water, and the electric push rod in the pressurization assembly in the pressurized treatment chamber No. 1 begins to move upward, driving the piston seal to move downward, and the pressure in the pressurized treatment chamber No. 1 gradually increases. When the pressure gauge of the pressurized treatment chamber No. 1 shows that the pressure reaches 0.7MPa, the electric push rod stops moving, and the pressurized treatment chamber No. 1 remains pressurized for 5s-20s to ensure that the rupture rate of pseudovacuoles in the cyanobacteria cells reaches more than 98%. At this time, the sedimentation effect of the cyanobacteria is better. At this time, the treatment work of the No. 1 pressurized treatment chamber is completed, and the algae inlet and outlet valves of the treatment chamber 1 are opened. Under the power of the hull movement and the flow pusher, new algae-rich water enters the treatment chamber 1 again. Under the action of the flow pusher, the new algae-rich water discharges all the pressurized algae-rich water from the outlet, completing a working cycle; the No. 1 pressurized treatment chamber and the No. 2 pressurized treatment chamber operate crosswise, that is, when the sampling of the No. 1 pressurized treatment chamber is completed and pressurization starts, the No. 2 pressurized treatment chamber starts sampling. When the No. 1 pressurized treatment chamber completes pressurization and starts sampling, the No. 2 pressurized treatment chamber starts pressurization.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
