Description

Technical Field

[0001] This utility model relates to the field of sea grape cultivation technology, and in particular to a pest control device for sea grape cultivation. Background Technology

[0002] *Caulerpa lentilifera*, commonly known as sea grapes, is native to the Ryukyu Islands and is an edible algae belonging to the genus *Caulerpa*. It is highly nutritious and has attracted widespread attention in aquaculture. To ensure the healthy growth and yield of sea grapes, it is necessary to regularly add pesticides to control pests and other pathogens. Furthermore, water agitation should be minimized during pesticide addition to prevent damage and detachment of the sea grapes. Existing technology discloses a pesticide device for sea grape aquaculture water (publication number CN218418174U). This device stores a certain amount of pesticide in a tank, and when the pesticide is sprayed into the aquaculture water through an L-shaped pipe using a water pump, the water is agitated and mixed. However, in actual use, because the pesticide mixes with the water in the aquaculture pond, the concentration of pesticide in the local water near the pesticide outlet becomes excessively high. This excessively high local concentration damages the sea grapes, and the agitation of the water to mix the pesticide also causes significant physical disturbance to the aquaculture environment. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a pest control device for sea grape cultivation, wherein the pesticide solution is mixed with the water outside the cultivation pond before being injected into the cultivation pond, thereby preventing the pesticide concentration in the water from being too high and reducing physical disturbance.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] A pest control device for sea grape cultivation includes a medicine storage tank, an elastic support, and a water pump. The elastic support is located at the bottom of the medicine storage tank. The water inlet of the water pump is connected to the cultivation pond through a first pipe, and the water outlet of the water pump is connected to the cultivation pond through a second pipe. The second pipe has a constricted neck with a reduced diameter, and the constricted neck is connected to the medicine storage tank through a third pipe.

[0006] Furthermore, the bottom surface area of ​​the inner cavity of the medicine container is 0.1 square meters, and the coefficient of the elastic support member is 0.98 N / m.

[0007] Furthermore, it also includes a base plate on which the water pump and elastic support are mounted.

[0008] Furthermore, the elastic support consists of four helical springs connected around the perimeter of the medicine container, with the bottom of each helical spring connected to the base plate.

[0009] Furthermore, a column is provided on the base plate, and the column is connected to the constricted neck of the first pipe.

[0010] Furthermore, the medicine container has an opening at the top, a raised ring around the outer periphery of the opening, and a lid on the raised ring.

[0011] Furthermore, several counterweights are provided on the top of the cover.

[0012] Furthermore, the third pipeline is equipped with a valve.

[0013] The beneficial effects of this invention are as follows: By incorporating a constriction in the second pipe, the medicine in the third pipe can naturally flow into the first pipe and mix thoroughly with the aquaculture water, ensuring uniform mixing of the medicine and aquaculture water and preventing localized excessive concentrations that could harm the sea grapes. Since the medicine is fully mixed and diluted with the aquaculture water before entering the aquaculture pond, no additional stirring is required, reducing physical disturbance to the aquaculture environment and helping to maintain a stable growth environment for the sea grapes. The slow and continuous addition of medicine ensures the continuity and stability of drug administration, reduces the need for manual intervention, improves work efficiency, and ensures effective pest control. The elastic support design allows the storage tank to automatically adjust its height according to changes in the amount of medicine, helping to maintain uniform concentration during the dosing process and ensuring consistent efficacy.

[0021] Example 1

[0022] Please refer to the attached document. Figures 1-3 This application provides a pest control device for sea grape cultivation, including a medicine storage tank 1, an elastic support 2, and a water pump 3. The elastic support 2 is located at the bottom of the medicine storage tank 1. The inlet of the water pump 3 is connected to the cultivation pond via a first pipe 4, and the outlet of the water pump 3 is connected to the cultivation pond via a second pipe 5. The second pipe 5 has a constricted neck 6 with a reduced diameter, and the constricted neck 6 is connected to the medicine storage tank 11 via a third pipe 7. When the water pump 3 is working, it pumps water out of the cultivation pond. The cultivated water flows back into the cultivation pond after passing through the first pipe 4, the water pump 3, and the second pipe 5. The constricted neck 6 in the first pipe 4 reduces the diameter, increasing the water flow velocity at that location. This increased flow velocity reduces the pressure at that location, thereby causing the medicine solution in the third pipe 7 to flow into the first pipe 4. (See attached...) Figure 1It is known that the inner diameter of the third pipe 7 is smaller than that of the first pipe 4, and the outlet of the third pipe 7 is perpendicular to the water flow direction of the locking part, making it easier for the medicine in the third pipe 7 to flow into the first pipe 4. The third pipe 7 is connected to the medicine storage tank 11, and the medicine in the medicine storage tank 11 flows through the third pipe 7 into the first pipe 4, where it mixes with the aquaculture water, thus diluting the medicine. The mixed medicine then enters the aquaculture pond through the first pipe 4, thereby achieving the purpose of adding medicine to the sea grape aquaculture pond. In this invention, the medicine is already mixed and diluted with the aquaculture water when it is added, which can prevent the local concentration of medicine from being too high when it is added to the aquaculture pond, thus preventing damage to the growth of sea grapes. This invention can slowly add the mixed and diluted medicine to the aquaculture pond without stirring the pond after addition. After the amount of medicine in the storage tank 1 decreases, the elastic support 2 pushes the tank upward, thereby reducing the height of the liquid level in the tank relative to the ground, reducing the height difference between the tank and the locking part, and maintaining uniform concentration during the dosing process. Optionally, the water pump 3 is a variable frequency pump.

[0023] Optionally, the bottom surface area of ​​the inner cavity of the medicine container is 0.1 square meters, and the coefficient of the elastic support 2 is 0.98 N / m. When the density of the medicine liquid in the medicine container is close to that of water, when the liquid level drops, the elastic support 2 extends and pushes the medicine container upward, thereby keeping the height of the medicine liquid relative to the ground constant and maintaining a uniform concentration during the dosing process.

[0024] Specifically, it also includes a base plate 8, on which the water pump 3 and the elastic support 2 are mounted. Using the base plate 8 to mount the water pump 3 and the elastic support 2 facilitates the movement of the device.

[0025] Specifically, the elastic support 2 consists of four helical springs 9, which are connected around the perimeter of the medicine container, with their bottoms connected to the base plate 8. The four helical springs 9 support the medicine container, maintaining its balance and ensuring stability during use.

[0026] Specifically, a column 10 is provided on the base plate 8, and the column 10 is connected to the constriction 6 of the first pipe 4. By using the column 10 to connect the constriction 6, the position of the constriction 6 is kept still, thus improving stability.

[0027] Example 2

[0028] Please refer to the attached document. Figures 1-3The difference between this embodiment and Embodiment 1 is that the medicine container has an opening 11 at the top, a raised ring 12 around the outer periphery of the opening 11, and a cover 13 on the raised ring 12. The raised ring 12 can improve the strength of the medicine container, and the cover 13 on the raised ring 12 can prevent impurities from entering the medicine container during use and prevent the third pipe 7 and the constriction 6 from becoming blocked.

[0029] Specifically, a plurality of counterweights 14 are provided above the lid 13. The counterweights 14 are fixed to the lid 13 and can be used to control the height difference between the liquid level inside the medicine container and the locking part. When there are more counterweights 14, the medicine container moves downwards, and at this time, the medicine container moves downwards relative to the constricted neck 6. When there are fewer counterweights 14, the medicine container moves upwards, and at this time, the medicine container moves upwards relative to the constricted neck 6. By adjusting the height difference between the medicine container and the constricted neck 6, the speed at which the medicine is delivered to the medicine container is adjusted.

[0030] Specifically, the third pipeline 7 is equipped with a valve 15. The drug delivery speed of the third pipeline 7 can be adjusted by the valve 15.

[0031] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
