[0002] In modern aquaculture, ensuring the quality of aquaculture water is crucial for the healthy growth of aquatic organisms. Adding pharmaceuticals to water is a common method for maintaining water quality and preventing and treating aquatic diseases.

[0003] At present, in actual aquaculture operations, there are two main ways to deliver drugs. One is through manual sprinkling, which completely relies on the operator's experience and physical strength. The operator holds a container of drugs, walks along the edge of the aquaculture pond or water, and sprinkles the drugs into the water. Due to the limitations of manual operation, it is difficult to ensure the consistency of the force, angle, and range of each sprinkling, resulting in extremely uneven distribution of drugs in the water body. Another method is to use pumping. Although pumping can improve the efficiency of drug delivery to a certain extent, it may still be pumping when the boat stops, which also causes uneven drug delivery. This unevenness seriously restricts the effect of the drug on the entire aquaculture water body, increases aquaculture costs and health risks to aquatic organisms, and there is an urgent need for a device that can improve the uniformity of drug delivery.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the embodiments of the present invention.

[0041] See also Figure 1 , Figure 1 This is a structural schematic diagram of a drug dispensing device for water treatment provided by an embodiment of the utility model. The device includes a drug dispensing tank, an air pump, a drug outlet pipe, a control valve and a toggle mechanism.

[0042] The dispensing tank can be set as a plastic container. The plastic material is lightweight and convenient to use. It can also be set as a metal tank, which has good aging resistance when used outdoors. The material of the dispensing tank is not specifically limited here. The dispensing tank is used to prepare the medicine to be put into the water body. When the medicine is prepared to the preset liquid level, the dispensing tank is sealed by the first tank cover. The dispensing tank includes a tank body and a first tank cover. A sealing ring can be provided on the first tank cover, and the first tank cover is connected to the tank body via a threaded structure; the original liquid of the medicine and water are prepared in proportion to prepare the medicine to be put into the water body. After the preparation of the medicine is completed, the dispensing tank is sealed by the first tank cover.

[0043] Furthermore, the dispensing tank is provided with a second tank cover for adding medicine and / or dilution water to the dispensing tank. When the medicine needs to be prepared, the second tank cover can be unscrewed, and the medicine, dilution water, etc. can be added to the dispensing tank. After the addition of the medicine and dilution water is completed, the second tank cover can be tightened.

[0044] The air pump can be set as an electric air pump, which is driven by a removable DC power supply. When the air pump is running, it can pump air into the sealed medicine dispensing tank. Of course, it can also be set as a foot-operated air pump, which can also be manually operated to pump air into the medicine dispensing tank when there is no power. The air pump is connected to the medicine dispensing tank through an air pipe. For example, a pipe hole is opened on the medicine dispensing tank, a seal is installed on the pipe hole, and the air pipe is inserted into the seal to connect the medicine dispensing tank and the air pump. The air pump is used to pump air into the medicine dispensing tank so that the internal air pressure of the medicine dispensing tank after it is sealed is greater than a preset value. The preset value can be set based on actual needs, and it can be used to allow the medicine to flow outward autonomously under the action of the internal air pressure. To further improve the convenience of use, a pressure gauge can be set on the medicine dispensing tank to facilitate the user to check the pressure of the air pumped in during use.

[0045] To improve the convenience of dispensing the medicine in the dispensing tank, a scale can be set on the dispensing tank to facilitate the user to control the ratio of the original solution and the dilution water when dispensing the medicine. The scale can be engraved on the dispensing tank or a sticker, and there is no specific limitation here.

[0046] The medicine outlet pipe is connected to the medicine dispensing tank and is used to transport the medicine in the medicine dispensing tank to the outside. The medicine outlet pipe can be set as a hard pipe made of PVC material. Please continue to refer to Figure 1 The drug outlet pipe can be inserted into the dispensing tank through the first tank cover, and a filter can be set at one end of the drug outlet pipe located in the dispensing tank based on actual needs to prevent impurities in the dispensing tank or the medicine from entering the drug outlet pipe.

[0047] The control valve can be configured based on actual needs, for example, as a valve with a return spring or as a butterfly valve. The key moving component of a butterfly valve is the disc, typically a disc that rotates around an axis within the valve body. The valve stem is connected to the disc, driving its rotation. The valve body provides space for the disc and other components, and its shape and size vary depending on the application scenario and pipeline specifications. A seal is installed between the disc and the valve body to ensure a tight seal when the valve is closed, preventing leakage of the reagent. The control valve is connected to the discharge pipe and controls the output of the reagent from the discharge pipe.

[0048] The toggle mechanism is mounted on the hull of the vessel housing the dispensing tank and connected to a control valve. The toggle mechanism extends into the water and is used to toggle the control valve open when the vessel moves, thereby delivering the agent to the water. The toggle mechanism can be a paddle structure connected to the butterfly plate of the control valve. When the vessel moves, the water flow drives the toggle mechanism to open the butterfly plate of the control valve. Because the pressure inside the dispensing tank is greater than the air pressure outside the tank, the agent can be released into the water under the action of the internal pressure of the dispensing tank.

[0049] It can be understood that as the ship's speed increases, the force exerted by the water on the toggle mechanism increases accordingly, and the opening of the control valve also increases accordingly, causing the flow rate of the drug delivery from the dispensing tank to increase accordingly. Conversely, as the ship's speed decreases, the flow rate of the drug delivery from the dispensing tank decreases accordingly. Therefore, the drug delivery device of the embodiment of the utility model can make the drug delivery rate adaptively follow the speed of the ship's movement, thereby improving the uniformity of drug delivery into the water.

[0050] For example, see Figure 2 , Figure 2 for Figure 1An enlarged schematic diagram of part A. The toggle mechanism includes a base plate and a main paddle. The base plate is mounted on the hull. The base plate can be a plastic plate or a metal plate and is mounted on the side of the hull with screws. It can be understood that since the hull's shape is mostly a curved structure, the provision of a base plate facilitates the installation of various components, such as fixing the medicine outlet pipe on the base plate with a pipe clamp. One end of the main paddle is connected to the switch shaft of the control valve, and the other end extends to the water body. A square hole can be opened at one end of the main paddle, which can be mounted on the control valve and locked with a nut; when the hull moves, the other end opens the control valve due to the force of the water body.

[0051] In a specific embodiment, the main paddle is configured as a long metal plate, such as a 1-2 mm stainless steel strip. The middle part of the main paddle is a twisted structure, and the twisting angle can be 90°. Setting the main paddle as a twisted structure can improve the strength of the main paddle. The main paddle extends to one end of the water body and its width is perpendicular to the direction of water flow when the hull moves.

[0052] In actual applications, water fluctuates due to environmental factors such as wind speed. If the main paddle is used to control the opening of the control valve, the opening adjustment is highly sensitive, and water fluctuations may cause the control valve to open. This can also cause the control valve to open passively when the vessel is stationary due to water fluctuations. Based on this, in one specific embodiment, the paddle mechanism also includes a limiter assembly.

[0053] The limit assembly is connected to the main paddle and is used to control the rotational damping of the main paddle within a preset range. The limit assembly can be a spring-loaded limit mechanism, for example, a compression spring mounted on the side of the main paddle. When the hull moves, the control valve needs to open against the spring force of the compression spring, which reduces the sensitivity of the control valve opening.

[0054] Specifically, the limit assembly includes an elastic member and a fastener. The elastic member is provided on the first side of the main paddle, which is the side closest to the stern in the longitudinal direction of the hull. One end of the elastic member is connected to the limit portion provided on the main paddle; it is fixedly connected to both the elastic member and the bottom plate, and the fastener is used to fix the other end of the elastic member to the bottom plate. The elastic member can be configured as a spring or a shrapnel, and its elastic deformation can suppress the sensitivity of the main paddle's rotation. Please continue to read Figure 2 When the elastic member is set as a compression spring, the limiting part can be set as a protrusion, and the protrusion and the compression spring are fitted together to prevent the compression spring from shifting during the compression process; the fastener can be set as a sleeve with a blind hole structure, and the fastener can be fixed to the base plate by screws or welded to the base plate.

[0055] Furthermore, the stop assembly includes a fixing member disposed on the second side surface of the main paddle, with the first and second side surfaces being located on either side of the main paddle. The fixing member may be a rubber block secured to the base plate by screws. The fixing member prevents the main paddle from moving toward the second side surface during water fluctuations, thereby preventing the control valve from accidentally opening due to water fluctuations.

[0056] In practical applications, the opening of the control valve is controlled by a single main paddle, which results in limitations in the opening control. Based on this, in a specific embodiment, the paddle mechanism further includes at least one auxiliary paddle, which is hinged to the main paddle. Figure 3 , Figure 3 This is a schematic diagram of the connection between the auxiliary and main paddles. Two auxiliary paddles are hinged to the main paddle in the figure. Rotating the auxiliary paddles changes the contact area between the entire paddle (main and auxiliary paddles) and the water. The diagram shows the auxiliary paddles in their open position. The entire paddle has a larger area. As the boat moves, the contact area between the water and the entire paddle increases, increasing the control valve's opening. Conversely, when the auxiliary paddles are retracted, the contact area between the water and the entire paddle decreases, reducing the control valve's opening. This adjustment method is convenient and suitable for adjusting the control valve's opening.

[0057] To further improve the uniformity of drug delivery, the device also includes an atomizing nozzle. This nozzle is connected to the outlet of the control valve. Due to the high air pressure within the dispensing tank, when the control valve is open, the atomizing nozzle atomizes the drug, ensuring a more even delivery of the atomized drug to the water body.

[0058] The technical solution provided in the embodiments of the present invention has at least the following technical effects or advantages:

[0059] The medicine dispensing device of the present invention includes a medicine dispensing tank, an air pump, a medicine discharge pipe, a control valve and a toggle mechanism. The medicine dispensing tank is used to prepare the medicine to be put into the water body. When the medicine is prepared to a preset liquid level, the medicine dispensing tank is sealed by a first tank cover; the air pump is connected to the medicine dispensing tank, and the air pump is used to pump air into the medicine dispensing tank so that the internal air pressure of the medicine dispensing tank after sealing is greater than a preset value; the medicine discharge pipe is connected to the medicine dispensing tank, and the medicine discharge pipe is used to transport the medicine in the medicine dispensing tank to the outside; the control valve is connected to the medicine discharge pipe, and the control valve is used to control the output amount of the medicine in the medicine discharge pipe; the toggle mechanism is installed on the hull where the medicine dispensing tank is placed, and is connected to the control valve; the toggle mechanism extends into the water body, and the toggle mechanism is used to toggle the control valve to open when the hull moves, so as to transport the medicine to the water body. After the preparation of the medicine is completed, the medicine-dispensing device can pump air into the medicine-dispensing tank through an air pump, so that the inside of the medicine-dispensing tank has a higher air pressure. When the hull moves, the toggle mechanism toggle the control valve to open, and under the action of the air pressure, the medicine in the medicine-dispensing tank is transported into the water body. The delivery rhythm of the medicine follows the hull, thereby improving the uniformity of the medicine delivery into the water body.
