Description

Technical Field

[0001] The present application relates to the technical field of enteromorpha removal, and in particular to an enteromorpha spraying device. Background Art

[0002] When dealing with the problem of excessive growth of aquatic plants such as Enteromorpha, spraying of pesticides is a commonly used means of control. This technology mainly involves spraying special algaecides or biological agents evenly on the water surface where Enteromorpha grows to inhibit the growth of Enteromorpha or directly kill it. According to the species of Enteromorpha, the growth environment and environmental protection requirements, select algaecides or biological agents that are effective against Enteromorpha and have less impact on the environment; after the spraying, follow-up monitoring is carried out to observe the death and sedimentation of Enteromorpha, as well as changes in water quality, and timely re-spray or adjust the dosage of the pesticide; it should be noted that when using chemical agents to control Enteromorpha, try to choose agents that are biodegradable and environmentally friendly, and operate under the guidance of professionals to avoid negative impacts on the aquatic ecosystem. At the same time, the comprehensive control strategy also includes a combination of biological control, physical control and other means.

[0003] Conventional existing algaecide spraying equipment uses drones or ships for spraying, during which the concentrated areas of Enteromorpha are accurately mapped to determine the spraying range and the best time to spray. Generally, the spraying is carried out during a period when Enteromorpha grows vigorously and the weather is suitable. However, due to the fluidity of seawater, the position of Enteromorpha is dynamic. If there is no structure to limit its range of activity, the removal effect of Enteromorpha will be reduced. Even if there is a corresponding limiting structure, the Enteromorpha removal operation is only carried out by spraying drones or spraying ships gradually approaching the limiting structure, and its removal efficiency is low. In addition, as the sea water fluctuates, some Enteromorpha will still cross the limiting structure and reach the coastline, making the Enteromorpha removal effect worse. Utility Model Content

[0004] The present invention provides a device for spraying Enteromorpha, and the specific implementation methods are as follows:

[0005] A Enteromorpha spraying device, comprising:

[0006] A plurality of buoys are connected end to end in sequence, and an interception net for acting on Enteromorpha is provided on the outside of the buoys, and the end buoys are connected to a deployment ship, and the deployment of the Enteromorpha interception net at the coastline is realized through two deployment ships;

[0007] There are two independent cavity structures inside the buoy. The bottom cavity is a counterweight bin used to limit the layout of the buoy. The top cavity is equipped with a chemical tube, and adjacent chemical tubes are connected to each other. The chemical tube is facing the direction of the enteromorpha and is provided with a spraying pipe passing through the cavity. The chemical tube is used to spray the enteromorpha agent from one side of the coastline to the outside.

[0008] Preferably, the upper layer of the float is set as a cavity warehouse, the medicine tube axially penetrates the cavity warehouse, adjacent medicine tubes are connected by a first connecting pipe, and a suction pump is serially connected to the first connecting pipe.

[0009] Based on the above technical solutions, large spraying ships are usually equipped with wide-width spraying systems, starting from the outer edge of the Ulva distribution area and gradually advancing toward the center to spray pesticides. UAVs, due to their high flexibility and strong maneuverability, can carry out precise spraying in locally dense or difficult-to-reach areas, and can also spray layer by layer from the outer edge of the Ulva to the central area; buoys with spraying devices are set near the shore or shallow water areas. These buoys can limit the movement of the Ulva from the inner edge of the Ulva. At the same time, the spraying pesticides and the external spraying ships or UAVs form an internal and external pincer attack, which increases the probability of contact between the pesticides and the Ulva, accelerates the death and cleaning process of the Ulva, and then maximizes the utilization efficiency of the pesticides, shortens the governance cycle, and reduces the potential impact on the surrounding ecological environment.

[0010] Preferably, the internal structure of the counterweight bin can be divided into two forms, namely:

[0011] Firstly, the interior of the counterweight bin is used to be filled with water, and a fixed pipe is provided at the end thereof, and adjacent fixed pipes are connected via a second connecting pipe.

[0012] Preferably, the first connecting pipe and the second connecting pipe are both flexible hoses.

[0013] Based on the above technical scheme, the counterweight bin plays a key balancing role in the Ulva control equipment. By filling it with water, it can ensure that the chemical tube always remains above the water surface, thereby ensuring that the chemical can be effectively and continuously sprayed to the Ulva growth area without being affected by water level changes; the use of flexible hoses to connect adjacent buoys enhances the adaptability and flexibility of the entire system when deployed on the water. It can bend freely even in waters with undulating waves or large terrain changes, ensuring that the chemical tube is always in an ideal working state; considering that the chemical tube may increase the resistance to chemical delivery due to its long length, and even cause problems with chemical delivery, the designer added suction pumps at appropriate intervals in the chemical tube, and the suction pump provides additional power.

[0014] Secondly, counterweight blocks are arranged in the counterweight bins, and adjacent counterweight bins are independent of each other.

[0015] Preferably, a plurality of spray pipes are equidistantly arranged along the length direction of the medicine tube, and a spray head is arranged at the end of the spray pipe where the portion where the spray pipe passes through the cavity is located.

[0016] Preferably, the spray head is of a shower head style, and a shower head aperture size adjustment portion is integrated therein.

[0017] Based on the above technical scheme, in the prior art, through the conventional aperture size adjustment part, for example, by changing the aperture size of the sieve hole or the nozzle by screwing, the flow rate and coverage range of the agent spraying can be flexibly adjusted to adapt to the control needs of different areas with different Enteromorpha densities; in the area of ​​the barrier net where Enteromorpha is most likely to gather, a buoy is set to spray the agent, and the removal boundary is clarified. The buoy and the spraying equipment carried by it can serve as the first line of defense for Enteromorpha control, forming a virtual agent barrier, effectively limiting the spread range of Enteromorpha, and preventing Enteromorpha from further approaching the coastline; since the density of Enteromorpha is relatively high at the barrier net, the buoy directly sprays the agent in this area, which can effectively remove the accumulated Enteromorpha in a targeted manner, and the agent can directly act on the Enteromorpha group, thereby improving the removal efficiency and reducing the ineffective loss of the agent.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. The utility model uses a spraying boat or a drone to gradually spray the agent from the outer edge of the Enteromorpha to the central area, and uses a buoy to spray the agent from the inner edge of the Enteromorpha to the central area, so the efficiency of removing the Enteromorpha is higher;

[0020] 2. The utility model provides independent hollow chambers and counterweight chambers, and fills the counterweight chamber with water to ensure that the medicine tube is always located above and out of the water, thereby improving the accuracy of the medicine spraying direction;

[0021] 3. The utility model has a simple structure. By adding a suction pump in the gap, the pressure loss caused by long-distance transportation of the agent is overcome, ensuring that the agent flows continuously and stably in the agent pipe, thereby improving the efficiency and coverage of the agent spraying, and further improving the effect of Enteromorpha control.

Adjacent fixed pipes 602 are connected by a second connecting pipe 8. In this structure, the first connecting pipe 7 and the second connecting pipe 8 are both flexible hoses.

[0042] Example 3

[0043] Reference Figures 2 to 7 Based on the above embodiments, in this embodiment, the agent selected is the biological bacterial agent special for Enteromorpha of Lelibao, and the bacterial agent is sprayed on the Enteromorpha on the interception net 1 in situ to observe its decomposition and sedimentation.
