Description

Technical Field

[0001] This invention relates to an algaecide dispensing device, belonging to the technical field of ecological algae control equipment. Background Technology

[0002] With the expansion of industrial and agricultural scale, large amounts of nutrients such as nitrogen and phosphorus flow into water bodies through multiple channels, including farmland drainage, municipal sewage discharge and industrial emissions, inducing explosive growth of algae and forming large-scale algal blooms.

[0003] The most common method for controlling and removing algae is to use algaecides. Existing methods for using algaecides include physical spraying and solid application. After the algaecides are applied, they need to diffuse through natural water convection, which results in poor diffusion efficiency and reduced algae removal efficiency. Summary of the Invention

[0004] This invention provides an algaecide dispensing device that solves the problems disclosed in the background art.

[0005] According to one aspect of this application, an algaecide dispensing device is provided, comprising a controllable water surface moving carrier, an algaecide storage device and a water agitation device disposed on the water surface moving carrier, an algaecide spraying channel disposed within the agitator of the water agitation device, the algaecide spraying channel being connected to the algaecide storage device via a controllable on / off conveying channel, a nozzle disposed on the water agitation device, the nozzle being located at the center of rotation of the agitator, and the nozzle being connected to the algaecide storage device via a controllable on / off connection channel; when the water surface moving carrier is on the water surface, the agitator and the nozzle are submerged in the water.

[0006] Furthermore, the water agitation device is mounted on the moving carrier on the water surface via an angle-adjustable bracket.

[0007] Furthermore, the water agitation device includes a rotating shaft, a nozzle is disposed at the first end of the rotating shaft, the second end of the rotating shaft is rotatably connected to an angle adjustment bracket, and several agitators are disposed on the rotating surface of the rotating shaft.

[0008] Furthermore, the rotating shaft is a hollow rotating shaft, and the internal channel of the rotating shaft is a section of the conveying channel, which is connected to the algaecide spraying channel and the nozzle spray hole.

[0009] Furthermore, the rotating shaft is a telescopic tube, and a drive unit for driving the telescopic tube to extend and retract is provided inside the telescopic tube.

[0010] Furthermore, the agitator is a folded propeller.

[0011] Furthermore, the angle adjustment bracket is a two-section robotic arm. The first end of the first arm section is connected to a water agitator, the second end of the first arm section is connected to the first end of the second arm section through a ball joint structure, and the second end of the second arm section is connected to a water surface moving carrier.

[0012] Furthermore, both the first and second arm segments are hollow arm segments. The internal channel of the first arm segment is connected to the internal channel of the second arm segment, and the connected channel serves as a section of the conveying channel. Along the conveying direction, a pumping device and a channel valve are sequentially installed in the internal channel of the first arm segment or the internal channel of the second arm segment.

[0013] The beneficial effects achieved by this invention are as follows: This invention uses an agitator and nozzle submerged in water to spray algaecide into the water. Simultaneously, the agitator generates a strong shear force, causing the surrounding water to move and creating turbulence. This allows the algaecide to mix rapidly and thoroughly with the water. Furthermore, the algaecide is sprayed out through the spray channel within the agitator, further accelerating its diffusion. Combined with the generated thrust, the algaecide is evenly diffused into a large area of ​​water, improving agent utilization and algae removal efficiency. It also enhances hydrodynamics, promotes multi-directional mixing of water, increases dissolved oxygen, effectively controls algae growth, improves lake and reservoir water quality, and alleviates eutrophication problems.

[0020] It should be noted that similar symbols and letters in the following figures represent similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0021] Furthermore, in the description of the embodiments of this application, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features.

[0022] This application discloses an algaecide dispensing device, which may include at least a controllable water surface moving carrier 1. An algaecide storage device and a water agitator 2 are installed on the water surface moving carrier 1. An algaecide spraying channel is opened in the agitator 3 of the water agitator 2. The algaecide spraying channel is connected to the algaecide storage device through a controllable conveying channel. A nozzle 4 is installed on the water agitator 2. The nozzle 4 is located at the center of rotation of the agitator 3. The nozzle 4 is connected to the algaecide storage device through a controllable connection channel. When the water surface moving carrier 1 is on the water surface, the agitator 3 and the nozzle 4 are submerged in the water.

[0023] It should be noted that, see Figure 1 The controllable water surface mobile carrier 1 can be a manned or unmanned small boat. In order to achieve uniform deployment, unmanned small boats are mainly used here. They can be remotely controlled by the shore control terminal or moved according to the built-in automatic program (similar to the program of a sweeping robot).

[0024] It should be noted that one or more water agitators 2 can be installed, but to improve efficiency, multiple agitators can be installed here. For specific installation locations, please refer to [reference needed]. Figure 1 Multiple water agitators 2 are evenly distributed on both sides of the small boat (as shown in the figure), so that when the small boat moves, algaecide can be sprayed over a wide area of ​​water.

[0025] Since algaecides are sprayed underwater, the spraying direction needs to be adjusted according to the water conditions to achieve optimal spraying results. For example, when algae are mainly distributed on the water surface or near the surface, the spraying angle can be adjusted to a small upward angle, such as 5° to 15° above the water surface, allowing the algaecide to spread rapidly in the shallow water below the surface and improving its effectiveness against surface algae. When algae are in the middle or lower layers of the water, the spraying angle can be adjusted to a larger downward angle, such as 20° to 30° below the water surface. Directional spraying allows the algaecide to act directly on the algae-rich water layer, reducing ineffective diffusion.

[0026] In order to achieve spray angle adjustment, in some embodiments, the water agitator 2 can be installed on the water surface moving carrier 1 through the angle adjustment bracket 5. The angle adjustment bracket 5 can be a controllable angle adjustment bracket 5, which can realize remote control. Taking an unmanned boat as an example, it can be controlled through the shore control terminal.

[0027] See Figure 2 and Figure 3 The angle adjustment bracket 5 here can be a two-section robotic arm (the drive components of the robotic arm are not shown in the diagram). The first end of the first arm section 51 is connected to the water agitator 2, and the second end of the first arm section 51 is connected to the first end of the second arm section through a ball joint structure. The second end of the second arm section is connected to the water surface moving carrier 1. The two-section robotic arm can achieve arbitrary angle adjustment of the water agitator 2.

[0028] It should be noted that, in order to reduce the number of components, in some embodiments, both the first arm segment 51 and the second arm segment 52 can be hollow arm segments. The internal channel of the first arm segment 51 is connected to the internal channel of the second arm segment 52, and the connected channel serves as a section of the conveying channel. Along the conveying direction, the pumping device 7 and the channel valve 6 are sequentially installed in the internal channel of the first arm segment 51 or the internal channel of the second arm segment 52. This hollow structure is not only lightweight, but the internal channel can also serve as a conveying channel, eliminating the need for additional conveying channels.

[0029] Figure 2 and Figure 3 In the middle, the pumping device 7 and the channel valve 6 are both installed in the second arm section 52. The pumping device 7 adopts a variable frequency pump. Both the variable frequency pump and the channel valve 6 can be controlled through the shore control terminal. The spraying intensity can be controlled by controlling the operating intensity of the variable frequency pump, such as controlling the spraying pressure to 0.3-0.5MPa.

[0030] In actual operation, the operating intensity of the variable frequency pump can be adjusted according to the water flow velocity and algae distribution. For example, when the water flow is weak and the algae distribution is sparse, the operating intensity of the variable frequency pump can be set to a lower level, such as adjusting the spraying pressure to approximately 0.3–0.35 MPa, to reduce water disturbance and improve the utilization rate of the agent. When the water has a certain flow velocity or is affected by wind and waves, and the algae distribution is wide, and it is necessary to consider the spraying coverage area, the operating intensity of the variable frequency pump can be appropriately increased, such as adjusting the spraying pressure to approximately 0.35–0.45 MPa, to ensure that the algaecide can effectively act on the target water area. Under conditions of high water flow velocity or high algae density, the operating intensity of the variable frequency pump can be further increased, such as adjusting the spraying pressure to approximately 0.45–0.5 MPa, thereby enhancing the spraying range and anti-diffusion capability.

[0031] It should be noted that the water agitator 2 can be a water-driven agitator 2, meaning that the water automatically drives the water agitator 2 to operate during the boat's movement. See also Figure 2 and Figure 3 The water agitation device 2 mainly includes a hollow rotating shaft, a nozzle 4 installed at the first end of the rotating shaft, and the second end of the rotating shaft is rotatably connected to the angle adjustment bracket 5, specifically rotatably connected to the first arm section 51. Several agitators 3 (such as three) are evenly installed on the rotating surface of the rotating shaft. The internal channel of the rotating shaft is a section of the conveying channel and is connected to the algaecide spraying channel and the spray hole of the nozzle 4.

[0032] It should be noted that five spray holes can be opened inside the nozzle 4, with the outer three rings having a diameter of 2mm and the inner two rings having a diameter of 1mm.

[0033] It should be noted that the agitator 3 can be a propeller, with a blade diameter of 0.4m. (See [reference]). Figure 4 The propeller can have three algaecide spraying channels inside, and the end of each channel can have a 0.5-1mm microhole. When the propeller rotates, the algaecide can be centrifugally sprayed, forming a dual-channel spray with the nozzle 4.

[0034] To facilitate folding when not in use, in some embodiments the propeller is a folding propeller, an existing type of propeller that achieves folding functionality through a mechanical or hydraulic system, so that the propeller folds up when not in use.

[0035] To adjust the spraying depth according to the water depth, in some embodiments, the rotating shaft of the water agitator 2 is directly a telescopic tube. A drive unit, such as an electric cylinder, is installed inside the telescopic tube to drive its extension and retraction, and this can be controlled via a control terminal on the shore. Figure 2 and Figure 3In the middle, the end of the electric cylinder is connected to the nozzle 4, which is fixed to the first end of the telescopic tube. The electric cylinder drives the telescopic tube to extend and retract, so that the length of the telescopic tube can be adjusted according to the water data and the distribution of algae to achieve more effective spraying.

[0036] For example, when algae are mainly distributed in the surface or near-surface areas of the water, and the water is shallow or has weak flow, the electric cylinder can be controlled to be in a retracted state, keeping the telescopic tube at a shorter length and the spray outlet located at a shallow position below the water surface. For instance, the length of the telescopic tube can be adjusted to 20%–40% of its maximum extension length to allow the algaecide to diffuse quickly in the surface water, avoiding excessive spraying and wasting the agent. When algae are distributed in the middle or lower layers of the water, or when there is some stratification in the water, the electric cylinder can be controlled to extend the telescopic tube, moving the spray outlet down to the target water layer. For instance, the length of the telescopic tube can be adjusted to 40%–70% of its maximum extension length, allowing the algaecide to act directly on the algae-rich water layer, improving treatment efficiency. In situations where the water is deep, algae are distributed in deep water, or the water flow velocity is high, the electric cylinder can be controlled to drive the telescopic tube to extend further. For example, the length of the telescopic tube can be adjusted to 70% to 100% of the maximum extension length, thereby placing the spray outlet in a deeper water body, reducing the impact of water flow on the diffusion of the agent, and enhancing the effect on the target area.

[0037] It should be noted that the water agitation device 2 mentioned above can also be a water agitation device driven by a drive device, that is, the water agitation device 2 can be directly driven by a controllable drive device (such as a motor). The motor can be installed in the internal channel of the first arm section 51, and the motor shaft can be driven to rotate through the transmission structure.

[0038] It should be noted that the algaecide storage device can be a separate component or a storage chamber within the water surface moving carrier 1. Figure 1 Taking a small boat as an example, a separate algaecide storage device can be set up, or the cabin can be used directly as an algaecide storage device.

[0039] Figure 1 The main method used is independent installation, that is, the algaecide storage tank is installed inside the small boat. The hull and the algaecide storage tank can be integrated into one structure. A feeding port is opened on the top of the algaecide storage tank, and a cover is installed at the feeding port. One side of the feeding port is hinged to one side of the cover. Magnets are installed on the other three sides of the feeding port to attract the cover. A handle is fixed on the top of the cover. When it is necessary to add material, the handle is pulled to overcome the magnetic force of the magnet and open the cover. After the material is added, the cover is closed and kept tightly closed by magnetic force.

[0040] by Figures 1-4 Taking the structure of the above-mentioned algaecide dispensing device as an example, the working process is as follows: When not in operation, all water agitators 2 are retracted and placed against the side of the boat by adjusting the angle bracket 5. Upon receiving the work instruction, the angle of the water agitator 2 is adjusted via the angle adjustment bracket 5, and the length of the telescopic pipe is adjusted to control the spraying depth. The operating intensity of the variable frequency pump is set, and after starting the small boat, the variable frequency pump and channel valve 6 are opened to ensure that the algaecide is evenly distributed through the nozzle 4 and the propeller micro-channel. (See also...) Figure 5 The propeller's rotation agitates the surrounding water, enhancing local hydrodynamics, promoting rapid mixing of the algaecide with the water, and allowing for uniform diffusion over a wide area, thus improving agent utilization and algae removal efficiency.

[0041] The aforementioned device sprays algaecide into the water via an agitator 3 and a nozzle 4 submerged in the water. Simultaneously, the agitator 3 generates a strong shear force, causing the surrounding water to move and creating turbulence. This allows the algaecide to mix rapidly and thoroughly with the water. Furthermore, the algaecide is sprayed out through the spray channel within the agitator 3, further accelerating its diffusion. Combined with the resulting thrust, the algaecide is evenly diffused over a large area of ​​water, improving agent utilization and algae removal efficiency. It also enhances hydrodynamics, promotes multi-directional mixing of the water, increases dissolved oxygen, effectively controls algae growth, improves lake and reservoir water quality, and alleviates eutrophication problems.

[0042] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
