Automatic water inlet and outlet circulation device for yacht fish tank

Abstract

This utility model discloses an automatic water inlet and outlet circulation device for a yacht fish tank, belonging to the field of fishing gear technology. Its key technical features include a temporary holding component, a replacement component, and a limiting component. During the temporary holding of fish, to prevent fish from dying in polluted water, a motor is activated to simultaneously open and close ball valves A and B. In use, when polluted water needs to be discharged, the output end of the motor is rotated forward, opening ball valves A and B. The polluted water inside the fish tank is then discharged through ball valve B, while fresh water from outside is introduced into the fish tank through ball valve A. This achieves water replacement without reducing the water volume, allowing fish to swim in an adequate amount of water and ensuring their freshness.

Description

Technical Field

[0001] This utility model belongs to the field of fishing gear technology, specifically relating to an automatic water inlet and outlet circulation device for yacht fish tanks. Background Technology

[0002] A yacht fish tank is a live fish holding or transport device designed specifically for yachts. It is mainly used in sea fishing or ornamental fish farming scenarios. Its purpose is to keep the caught fish alive and maintain water quality and oxygen supply through a circulating water system.

[0003] In existing technologies, most yacht fish tanks are used for temporary storage of fish. During storage, fish excrement or impurities from fishing may accumulate at the bottom of the tank, which can lead to poor water quality inside the tank. Fish caught and raised in polluted water may die. Existing technologies typically require draining the polluted water and replacing it with fresh water to ensure the survival rate of the fish. However, since both draining and replacing the water are manually controlled, the amount of water drained and replaced may vary, potentially reducing the water volume inside the tank. This can affect the activity of the fish and consequently their freshness. To address these issues, we propose an automatic water inlet and outlet circulation device for yacht fish tanks. Utility Model Content

[0004] The purpose of this invention is to provide an automatic water inlet and outlet circulation device for yacht fish tanks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic water inlet and outlet circulation device for a yacht fish tank includes a temporary holding component, which is equipped with a replacement component and a limiting component, and an oxygenation device.

[0018] Please see Figures 1-6 This utility model provides an automatic water inlet and outlet circulation device for a yacht fish tank, including a temporary holding component 1, a replacement component 2 and a limiting component 3 on the temporary holding component 1, and an oxygenation device 4 on the temporary holding component 1. The temporary holding component 1 includes a fish tank 11, which is hollow inside and has a chamfered structure on the lower inner wall. The surface of the fish tank 11 is provided with a water inlet pipe 16 and a drain pipe 17.

[0019] Specifically, after the fish are caught, if they need to be temporarily held, they can be placed inside the fish tank 11 and an appropriate amount of water can be added. During the holding period, if the fish excrete waste or if the surface of the fish is not cleaned during capture, resulting in water pollution, the water inside the fish tank 11 can be replaced by controlling the opening and closing of ball valve A 21 and ball valve B 24, thereby ensuring the survival of the fish.

[0020] In this embodiment, the lower end of the fish tank 11 is provided with multiple support members 12, and the fish tank 11 is provided with two extension members 18. Extension rod A 22 and extension rod B 25 respectively rotatably penetrate the surfaces of the two extension members 18.

[0021] Specifically, in order to ensure that the fish tank 11 can be set stably, multiple support members 12 are provided at its lower end. In use, in order to ensure that the A extension rod 22 and the B extension rod 25 are set stably, they are rotated to pass through the two extension members 18 respectively, and the extension members 18 can limit their movement.

[0022] In this embodiment, the fish tank 11 is provided with a fixing member A 14, the fixing member A 14 is provided with a sleeve rod 19, the sleeve rod 19 is provided with a sleeve piece 15, and the sleeve piece 15 is provided with a closing cover 13.

[0023] Specifically, in order to close the opening at the top of the fish tank 11 and prevent fish from jumping out, a closing cover 13 can be installed on the fish tank 11. The closing cover 13 can be rotated by fitting the sleeve 15 onto the sleeve rod 19.

[0024] In this embodiment, the extension member 18 is provided with an installation box, and the ends of extension rod A 22 and extension rod B 25 are respectively provided with gear A 23 and gear B 26, and gear A 23 and gear B 26 are meshed.

[0025] Specifically, in order to facilitate the subsequent installation of the motor 27, a mounting box is provided on the extension part 18. In order to drive the A extension rod 22 and the B extension rod 25 to rotate simultaneously, and thus open the A ball valve 21 and the B ball valve 24 at the same time, the A gear 23 and the B gear 26 are respectively provided at the ends of the A extension rod 22 and the B extension rod 25, and the two are meshed.

[0026] In this embodiment, the replacement component 2 also includes a motor 27, which is disposed in the mounting box and the output end of the motor 27 is connected to the B gear 26.

[0027] Specifically, in order to automatically drive the B gear 26 to rotate, a motor 27 can be installed in the mounting box, and the output end of the motor 27 can be connected to the B gear 26. At this time, the A extension rod 22 and the B extension rod 25 can be driven to rotate by starting the motor 27.

[0028] In this embodiment, the limiting component 3 includes a B fixing member 32, which is disposed on the closed cover 13. A C fixing member 33 is disposed on the fish tank 11. The surface of the C fixing member 33 is provided with a chamfered structure, and the surface of the B fixing member 32 is provided with a through hole. An insertion rod 31 is disposed on the B fixing member 32. The limiting component 3 also includes a snap-fit ​​member 34. A limiting groove is provided on the surface of the insertion rod 31. A rectangular plate 35 is disposed on the C fixing member 33. An electrically controlled telescopic rod 36 is disposed on the rectangular plate 35. The snap-fit ​​member 34 is connected to the electrically controlled telescopic rod 36.

[0029] Specifically, when limiting the closing cover 13, the insertion rod 31 can be inserted into the through hole. At this time, it can be locked by the snap-fit ​​part 34. In use, the snap-fit ​​part 34 can always be locked in the limiting groove by the electric telescopic rod 36, so that the insertion rod 31 can be set stably.

[0030] In this embodiment, the sealing cover 13 is provided with an oxygen injection hole, and the sealing cover 13 is provided with an oxygen injection device 4, and the oxygen discharge pipe of the oxygen injection device 4 is located in the oxygen injection hole.

[0031] Specifically, in order to ensure that the fish inside the fish tank 11 have sufficient oxygen during the temporary holding period, an oxygenation device 4 can be installed on the closed cover 13, and the oxygen discharge pipe of the oxygenation device 4 can be installed in the oxygenation hole, so that the oxygen generated by the oxygenation device 4 can be injected into the fish tank 11.

[0032] The working principle and usage process of this utility model: When people catch fish on a yacht, they usually cannot process the fish immediately. At this time, it is necessary to use a fish tank to temporarily hold the fish. When temporarily holding the fish, an appropriate amount of water can be injected into the fish tank 11 first. Then, the fish can be placed inside the fish tank 11. By rotating the sealing cap 13, the upper opening of the fish tank 11 is sealed, thereby preventing the fish from jumping out of the fish tank 11 due to violent struggle.

[0033] In use, to prevent the sealing cover 13 from deflecting, the insertion rod 31 can be inserted into the through hole, and the snap-fit ​​34 can be engaged in the limiting groove. This allows the insertion rod 31 to be stably inserted into the through hole, so that the sealing cover 13 can stably close the opening of the fish tank 11. When the fish need to be taken out later, the sealing cover 13 needs to be rotated to open the opening of the fish tank 11. At this time, the electric telescopic rod 36 can be retracted to disengage the snap-fit ​​34 from the limiting groove, allowing the insertion rod 31 to slide up and down again, thereby releasing the limiting of the sealing cover 13.

[0034] During the temporary holding of fish, the water inside the fish tank 11 may become contaminated due to fish excrement, dust, sand, or other contaminants, either from fish excrement or because the fish were not cleaned at the time of initial capture. To prevent fish from dying in contaminated water, motor 27 can be activated, which in turn drives gear B 26 to rotate, which in turn drives gear A 23 to rotate. This causes extension rods A 22 and B 25 to rotate synchronously. Since extension rods A 22 and B 25 are connected to the control shafts of ball valves A 21 and B 24 respectively, when... When extension rods A and B rotate, they can simultaneously open and close ball valves A and B. During use, when it is necessary to discharge polluted water, the output of the forward-rotating motor 27 can be used to open ball valves A and B. At this time, the polluted water inside the fish tank 11 will be discharged through ball valve B, while fresh water from the outside can be introduced into the fish tank 11 through ball valve A, thus realizing the replacement of water without reducing the water volume. This allows fish to swim in an appropriate amount of water, thereby ensuring the freshness of the fish.

[0035] When temporarily holding fish, in order to prevent the fish inside the fish tank 11 from dying due to lack of oxygen, an oxygenation device 4 can be installed on the closed cover 13, and the oxygen discharge pipe of the oxygenation device 4 can be extended into the fish tank 11 and down to the bottom of the water body, so that oxygen can be continuously injected into the water, thereby preventing the fish from dying due to lack of oxygen.

[0036] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0037] To ensure proper meshing of the two helical gears, the following conditions must be met: 1. Equal normal modules: The normal modules of the two gears must be the same, which is the basic parameter for gear machining and meshing; 2. Equal normal pressure angles: The normal tooth profile angles (pressure angles) must be consistent to ensure the matching of tooth profiles; 3. Equal helix angles and opposite directions: The absolute values ​​of the helix angles must be the same, but the directions of rotation must be opposite, i.e., one left-handed and one right-handed, to counteract axial forces and ensure smooth meshing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
