[0003] Existing marine pesticide spraying devices typically have nozzles fixedly mounted on the sides or ends of the hull, limiting their coverage area to the hull width and nozzle spray angle. For wider rivers or lakes, fixed nozzles have limited spraying distance, only covering a localized area near the hull. To cover a wider area, the vessel needs to make multiple round trips, increasing travel time and fuel consumption. Furthermore, repeated spraying can lead to excessively high pesticide concentrations in localized areas, disrupting the aquatic ecosystem. Therefore, this invention proposes a novel solution.

This device can solve the problem that for wider rivers or lakes, the spraying distance of fixed nozzles is limited, and can only cover a local area of ​​water near the hull. If a wider area is to be covered, the ship needs to be driven back and forth multiple times, which not only increases the sailing time and fuel consumption, but may also lead to excessively high concentrations of pesticides in local waters due to repeated spraying, thus disrupting the ecological balance of the water body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marine spraying device for eutrophication control, comprising a mounting base and a nozzle, wherein a fixed frame is fixedly connected to the upper end of the mounting base;

[0009] Preferably, the adjustment assembly further includes a first fixed bracket, which is fixedly connected to the upper end of the fixed frame, and an electric telescopic rod is hinged to the surface of the fixed frame;

[0010] The output end of the electric telescopic rod is hinged to a first connecting plate, and the first connecting plate is fixedly connected to a first connecting shaft.

[0011] The lower ends of the second and third connecting shafts are respectively fixedly connected to the first gear and the second gear.

[0033] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0034] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and 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 this utility model.

[0035] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] Please see Figure 1-7 This utility model provides a technical solution: a marine spraying device for eutrophication control, with adjustable nozzle spacing.

[0038] The core adjustment function of the device is achieved by two sets of adjustment components symmetrically arranged on the left and right sides of the fixed frame 3, which complete the flexible adjustment of the nozzle 21 spacing through a parallelogram mechanism.

[0039] When the electric telescopic rod 11 extends or retracts, it will push the first connecting plate 10 to drive the first connecting shaft 7 to rotate, so that the first connecting rod 8 swings around the first connecting shaft 7 as the fulcrum.

[0040] Since the second fixed bracket 6, the first connecting rod 8, the second connecting plate 13, and the third connecting rod 15 form a parallelogram structure, when the first connecting rod 8 swings, it will drive the third connecting rod 15 to swing synchronously through the second connecting plate 13. At the same time, the second connecting rod 9 maintains a parallel relationship with the movement of the mechanism, and finally realizes the synchronous adjustment of the distance between the two nozzles 21.

[0041] The first gear 16 and the second gear 17 at the lower end of the second connecting shaft 12 and the third connecting shaft 14 mesh with each other to ensure that the connecting rods on both sides move in a coordinated manner and avoid jamming.

[0042] Drug delivery

[0043] Diaphragm pump 18 provides power for the delivery of medicine solution. It draws medicine solution from medicine tank 2 through first medicine pipe 19 at the water inlet end, and then diverts it to two second injection pipes 20 through three-way valve, and finally sprays it out from nozzle 21.

[0044] The second injection tube 20 is arranged along the first connecting rod 8 and the third connecting rod 15, and can swing synchronously with the connecting rod to ensure smooth and unobstructed delivery of the medicine.

[0045] Chemical treatment

[0046] The medicine tank 2 is used to store the treatment solution, and the filter screen 25 inside the injection pipe 22 can filter impurities in the added solution to prevent clogging of the pipe and nozzle 21.

[0047] The agitator 26 inside the agent tank 2, including a drive motor, a stirring shaft, and stirring blades, can stir the liquid medicine to ensure that the compound agent is mixed evenly and that the concentration of the sprayed liquid medicine is consistent.

[0048] By adjusting the parallelogram mechanism composed of the components, the outward expansion distance of the two nozzles 21 can be adjusted in real time according to the width of the water area under the drive of the electric telescopic rod 11. Combined with the movement of the hull, the spraying range can be greatly expanded, the number of times the ship goes back and forth can be reduced, the sailing time and fuel consumption can be reduced, and it is suitable for rivers, lakes and other scenarios of different widths.

[0049] The flexible nozzle spacing adjustment can avoid the problem of repeated spraying caused by the limited coverage of fixed nozzles, and prevent excessively high concentrations of chemicals in local water areas from disrupting the ecological balance of the water body.

[0050] The agitator 26 ensures uniform mixing of the pesticide solution, and the diaphragm pump 18 provides stable pesticide delivery, ensuring consistent pesticide concentration and improving the eutrophication control effect.

[0051] The two sets of symmetrically arranged adjustment components can be operated independently to adapt to the spraying needs of irregular water areas such as winding lake shorelines;

[0052] The connecting discs 5 on the left and right sides of the fixed frame 3 support the connecting rod structure, improve the stability during the adjustment process, and ensure a smooth spraying process.

[0053] Filter 25 filters out impurities, reducing the risk of clogging in pipes and nozzles 21;

[0054] When the medicine cap 24 is closed, it can prevent the medicine from evaporating and debris from falling into the medicine tank 2. The medicine drain pipe 23 makes it easy to drain the residual medicine and clean the equipment when changing the medicine, thus extending the overall service life of the device.

[0055] Example 1:

[0056] When operating in narrower waterways, the electric telescopic boom 11 retracts, causing the parallelogram mechanism to retract and reducing the distance between the two nozzles 21. The diaphragm pump 18 and agitator 26 are started, and the well-mixed solution is transported to the nozzles 21 through pipelines. As the boat moves slowly, the nozzles 21 spray the solution to both sides, covering the entire width of the waterway, completing the treatment without having to travel back and forth.

[0057] Example 2:

[0058] When treating wide lakes, the electric telescopic rod 11 extends, pushing the parallelogram mechanism to unfold and increasing the outward expansion distance of the nozzle 21. The connecting plate 5 supports the first connecting rod 8 on both sides of the fixed frame 3, improving the stability of the first connecting rod 8 during movement, expanding the spraying range, and ensuring uniform spraying. Depending on the shape of the lake, the single-sided adjustment component can operate independently, reducing the outward expansion distance of the nozzle 21 closer to the lake shore, preventing the pesticide from being sprayed onto the land and wasting it.

[0059] Example 3:

[0060] When changing the chemical solution, open the valve on the drain pipe 23 to drain the remaining chemical solution in the chemical tank 2, add clean water through the injection pipe 22, and start the agitator 26 and diaphragm pump 18 to flush the pipes and nozzles 21 to prevent the mixing of different chemical solutions from causing sedimentation. After cleaning, add new chemical solution, filter impurities through the filter screen 25, and then you can start working again.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
