Description

Technical Field

[0001] This invention relates to the field of ecological environment management, and in particular to a propulsion-type mechanical pressurized cyanobacteria control vessel. Background Technology

[0002] Algal blooms are a major environmental problem facing water bodies globally, especially in eutrophic lakes. Excessive cyanobacterial growth leads to water quality deterioration, ecosystem imbalance, and cyanobacterial toxins that threaten aquatic ecological security. Because cyanobacteria have short growth cycles and possess pseudo-empty cells, they easily gain a dominant growth position. Traditional methods for controlling algal blooms, such as chemical algae control, physical harvesting, and biological agents, have significant drawbacks, including secondary pollution, low treatment efficiency, poor algae control effects, and high costs.

[0003] Because cyanobacteria possess pseudo-vacuoles, they can rise or fall in water by adjusting buoyancy, thus gaining a competitive advantage. These pseudo-vacuoles are easily ruptured under certain pressure conditions; after rupture, the algae lose buoyancy and sink to the bottom, eventually dying out due to the loss of photosynthesis. Existing pressurized algae control devices fall into two categories: fixed types, i.e., algae control wells, which can achieve large-scale algae control but are immobile, have poor mobility, and high energy consumption; and algae control vessels, which typically have a processing capacity of several hundred tons per hour, using high-pressure pumps to provide pressure and introduce algae solutions, but also have 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 this invention is to provide a propulsion-type mechanical pressurized cyanobacteria control vessel. Utilizing the principle of pressurized algae control, and through the design of a propulsion-type design and a mechanical pressurization device, it achieves the goal of controlling cyanobacteria blooms efficiently and with low energy consumption. This device is mainly used for emergency control of cyanobacterial blooms.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] This invention provides a propulsion-type mechanically pressurized cyanobacteria control vessel, comprising:

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

[0009] An algae collecting head, which is oscillatingly connected to the front end of the hull;

[0010] Buoyancy chambers are located at the front and rear ends of the bottom of the hull.

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

[0012] A pressurization treatment chamber is located in the middle of the hull and is connected to the water collection tank. The bottom of the pressurization treatment chamber is provided with a discharge outlet.

[0013] A pressurization assembly is disposed within the pressurization chamber.

[0014] Preferably, the stern of the hull is equipped with a power unit and a generator.

[0015] Preferably, the bow of the hull is provided with a bridge.

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

[0017] Preferably, the algae collecting head unfolds into a sieve-like structure.

[0018] Preferably, the algae collection head includes a support rod, which is hinged to both sides of the head of the hull and connected to an electro-hydraulic support rod. A roll of material is fixed between the support rods on both sides, and the roll of material is connected to the hull by a hinged retractable flexible connector.

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

[0020] Preferably, there are two or more pressurization chambers, which are arranged side by side in the middle of the hull.

[0021] Preferably, the pressurized treatment chamber is provided with staggered horizontal partitions with a spacing of 0.2-0.5m; and a flow booster is provided at the bottom of the pressurized treatment chamber.

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

[0023] The present invention achieves the following beneficial technical effects compared to the prior art:

[0024] (1) The pressurized treatment chamber adopts a layered design. The cyanobacteria are pushed and run in the pressurized treatment chamber. 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 gushing water of the ship and the power of the small-powered propeller are used to realize the injection and discharge of the sample. There is no need for the water pump to lift the sample. The micro-power operation can reduce the energy consumption of the injection and discharge to about 10% of the existing equipment.

[0026] (3) The cylinder of the pressurization component is connected to the pressurization treatment chamber. After the sample is injected, the cylinder and the pressurization treatment chamber are filled with algae solution. Because water has poor compressibility, the piston seal only needs to move down a small distance to make the working pressure of 0.7 MPa in the pressurization treatment chamber reach the working pressure. The pressurization component uses the lever principle. The up and down movement of the electric push rod drives the piston seal to move up and down, thereby pressurizing the pressurization 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 pressurization algae control ship). It is 5-10% of its energy consumption, with good energy saving effect and high treatment efficiency.

[0027] (4) Since the cyanobacteria whose pseudo-vacuoles have broken are easy to recover under photosynthesis, the outlet of this application is designed to be located at the bottom of the hull, so that the outlet is located 1m below the water surface when the algae control vessel is working normally. This is conducive to helping the cyanobacteria whose pseudo-vacuoles have broken continue to sink to the bottom of the water. It can effectively avoid the cyanobacteria that have been pressurized from being overturned to the surface due to the disturbance of the hull's movement, thus obtaining the conditions for self-recovery and 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 severe, it can accumulate in the 0-20cm water layer or even the 0-50cm water layer. Based on this characteristic, this application sets up a sieve-shaped algal collection head, and the depth of the algal collection head in the water layer can be freely adjusted so that it can collect algal liquid in any water layer of 0-50cm, such as the 0-5cm water layer, the 0-10cm water layer, etc., to collect high-concentration algal liquid in a targeted manner and improve 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 continuous operation of the algae control process;

[0030] (7) The present invention provides a propulsion-type mechanical pressurization cyanobacteria control vessel. The propulsion-type mechanical pressurization cyanobacteria control vessel is self-powered and can flexibly operate to the water area to be treated. Its mobility is excellent. It uses the lever principle and electric push rod for pressurization, which is more energy-efficient and faster than the method of directly pressurizing the water body using air compressors, water pumps, etc. Through the combined design of the sieve-shaped algae collection head, algae inlet position, and layered pressurization treatment chamber, the vessel's propulsion and propeller are used to realize the entry and discharge of high algae water. Compared with the method of using water pumps for sampling, the operating energy consumption is greatly reduced. It is applicable to the control of cyanobacteria in lakes, reservoirs, water sources, landscape water bodies and other water areas. Attached Figure Description

[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Example 1:

[0047] This embodiment provides a propulsion-type mechanically pressurized cyanobacteria control vessel, such as... Figure 1-9 As shown, it includes:

[0048] Hull 1, the upper surface of hull 1 is equipped with a deck, which can be directly modified from an existing ship. The size of hull 1 can be flexibly adjusted according to different usage scenarios. The general design parameters are 6-24m in length, 2-8m in width and 0.5-3m in depth.

[0049] Algae collecting head 2 is swayably connected to the front of the hull 1; its size can be flexibly adjusted according to the different hulls. Generally, the algae collecting head is about 2-4m wider than the hull and its length is about 2-4m longer than the bow.

[0050] Buoyancy chamber 3 is located at the front and rear of the bottom of hull 1; it is generally 2-4m long, and its width and depth are consistent with the hull; the dimensions of each buoyancy chamber are consistent to ensure that the overall buoyancy of the hull is consistent;

[0051] Water collection tank 4 is connected to the rear end of algae collection head 2; it is located between the buoyancy chamber and the deck.

[0052] The pressurized treatment chamber 5 is located in the middle of the hull 1 and is connected to the collection pool 4. The number of chambers can be adjusted according to actual needs. The width of a single treatment chamber is 1-5m. The bottom of the pressurized treatment chamber 5 is equipped with an outlet 6 to ensure that the treated algae can be discharged into the bottom of the water body.

[0053] The pressurization component 7 is installed inside the pressurization treatment chamber 5 and is used to pressurize the algae to rupture its pseudo-vacuoles, thereby achieving the effect of eliminating algae.

[0054] In one implementation, the stern of the hull 1 is equipped with a power unit 8 and a generator 9. The power unit 8 provides power for the movement of the hull 1, allowing it to move flexibly to the waters to be treated, and its maneuverability is excellent. The generator 9 provides power for the operation of other equipment.

[0055] In one implementation, a bridge 10 is provided at the front of the hull 1 for the convenience of the user to drive.

[0056] As one implementation method, guardrails 11 are provided on the side edges of the hull 1, which provide good protection.

[0057] As one implementation method, the algae collecting head 2 unfolds into a sieve-like structure, which can effectively increase the collecting area and thus improve the collecting efficiency.

[0058] In one embodiment, the algae collection head 2 includes a support rod 21, which is hinged to both sides of the head of the hull 1 and connected to an electro-hydraulic support rod 22. The support rod 21 can be adjusted to swing through the electro-hydraulic support rod 22, thereby adjusting the water depth to ensure a good collection effect. A roll material 23 is fixed between the support rods 21 on both sides. The roll material is made of polyethylene polypropylene waterproof roll material. The roll material 23 is connected to the hull 1 through a hinged retractable flexible connector 24. The hinged retractable flexible connector 24 is made of polyethylene and can be extended, retracted, and folded in any direction.

[0059] In one implementation, the front end of the water collection tank 4 is provided with a water collection tank algae inlet 41, which is connected to the algae collection head 2; the front end of the pressurized treatment chamber 5 is provided with an algae inlet 51, the size of which is generally selected between 500×500mm and 1000×500mm, the pressurized treatment chamber algae inlet 51 is connected to the water collection tank 4, and a valve opening and closing mechanism 52 is provided at the pressurized treatment chamber algae inlet 51.

[0060] In one implementation, there are two or more pressurized treatment chambers 5, which are arranged side by side in the middle of the hull 1.

[0061] As one implementation method, multiple horizontal baffles 54 are staggered inside the pressurized treatment chamber 5, with a spacing of 0.2-0.5m between the baffles 54, to ensure that the internal water flows out of the pressurized treatment chamber in an S-shape from top to bottom; a flow booster 53 is provided at the bottom of the pressurized treatment chamber 5 to ensure the direction of water flow.

[0062] In one embodiment, the pressurization assembly 7 includes a cylinder 71, the bottom of which is connected to the pressurization chamber 5. A piston seal 72 is movably fitted inside the cylinder 71. The top of the piston seal 72 is hinged to one end of a control rod 74 via 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 inside the pressurization chamber 5. By utilizing the lever principle, the up-and-down movement of the electric push rod drives the piston seal to move up and down, thereby pressurizing the pressurization chamber.

[0063] This invention provides a propulsion-type mechanical pressurized cyanobacteria control vessel. Its usage and working principle are as follows: First, when the cyanobacteria control vessel is launched for the first time, the pressurization chambers must be filled with water using a water pump to achieve the normal draft depth required for normal operation, i.e., the upper edge of the algae inlet is approximately 0-10 cm below the water surface. Second, the power equipment and generator are started. Based on the water layer where cyanobacteria accumulate on the surface, the depth of the algae collection head submerged in the water layer is adjusted via an electro-hydraulic lever to ensure targeted collection of high-concentration algae solutions. Third, the algae inlet and outlet of pressurization chamber 1 are opened via a valve opening / closing mechanism, while the algae inlets of the other pressurization chambers are closed. The propulsion device is activated, and the vessel moves forward. Utilizing the thrust generated by the forward movement of the vessel and the power of the propulsion device located in the pressurization chamber, the algae-rich water is pushed into the algae collection head and enters the collection tank through the algae inlet. When pressurization chamber 1 is full of algae-rich water, the valve opening / closing mechanism closes pressurization chamber 1. The algae inlet and outlet of the No. 1 pressurized treatment chamber are opened simultaneously, and the ship continues to move forward, repeating the process of algae entering the No. 1 pressurized treatment chamber. At this time, the No. 1 pressurized treatment chamber is filled with algae-rich water. The electric push rod in the pressurization component of the No. 1 pressurized treatment chamber begins to move upward, driving the piston seal to move downward. The pressure in the No. 1 pressurized treatment chamber gradually increases. When the pressure gauge of the No. 1 pressurized treatment chamber shows that the pressure reaches 0.7MPa, the electric push rod stops moving. The No. 1 pressurized treatment chamber is kept in pressurized state for 5s-20s to ensure that the rupture rate of pseudo-empty cells in the cyanobacteria cells reaches more than 98%. At this time, the cyanobacteria sedimentation effect is good. At this point, the processing work in the No. 1 pressurized treatment chamber is completed. The inlet and outlet valves of the algae in the treatment chamber are opened. Under the power of the ship's movement and the propulsion of the thruster, new algae-rich water is introduced into the treatment chamber. Under the propulsion action, the new algae-rich water discharges all the pressurized algae-rich water from the outlet, completing one working cycle. The No. 1 and No. 2 pressurized treatment chambers operate in an alternating manner. That is, when the No. 1 pressurized treatment chamber finishes sampling and starts pressurization, the No. 2 pressurized treatment chamber starts sampling. When the No. 1 pressurized treatment chamber finishes pressurization and starts discharging samples, the No. 2 pressurized treatment chamber starts pressurization.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] It should be noted that the components mentioned in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
