Description

Technical Field

[0001] The utility model relates to the technical field of oxygenation devices, in particular to an automatic oxygenation device for a larval pool. Background Art

[0002] The automatic oxygenation device for larval pools is designed to ensure that aquatic larvae such as fish and shrimp can obtain sufficient oxygen in the water. It mainly increases the dissolved oxygen content in the water through mechanical or physical methods, thereby ensuring the normal growth and development of aquatic larvae.

[0003] Currently, the common automatic oxygenation devices for larval ponds include impeller aerators, which use an electric motor to drive the impeller to rotate at high speed, stirring the water and generating water flow. This water flow allows water and air to fully contact, thereby increasing the dissolved oxygen content of the water; waterwheel aerators, which use the high-speed rotation of the blades to hit the water surface and stir air into the water. This method can also increase the contact area between water and air and increase the dissolved oxygen content; jet aerators, which use a submersible pump to eject water at high speed from the nozzle in the jet tube, generating negative pressure to inhale air. The water and air are mixed in the mixing chamber and then diffused into the pond to achieve oxygenation.

[0004] However, the oxygenation area of ​​some automatic oxygenation devices in the prior art is limited to a certain area, and it is impossible to achieve uniform oxygenation in the whole pool, which may lead to insufficient dissolved oxygen in certain areas of the pool and affect the growth and development of the larvae. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an automatic oxygenation device for a larval pool to solve the technical problem that the oxygenation area of ​​some automatic oxygenation devices in the prior art is limited to a certain area and cannot achieve uniform oxygenation in the entire pool, which may lead to insufficient dissolved oxygen in certain areas of the pool and affect the growth and development of the larvae.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an automatic oxygenation device for a larval pool, comprising a pool body, support rods are fixedly connected to the top of both sides of the pool body, support plates are arranged on the top of the support rods, air storage boxes are arranged on both sides of the pool body, piston blocks are movably installed in the air storage boxes, movable rods are fixedly connected to the top of the piston block, movable blocks are arranged on the top of the movable rods, one-way air inlet and one-way air outlet are opened on both sides of the air storage box, sliding rods are arranged on both sides of the pool body, a first air guide block is slidably arranged on the sliding rod, an air delivery hose is arranged between the first air guide block and the one-way air outlet, a connecting rod is arranged on the inner side of the movable block, a connecting rod is rotatably connected between the connecting rod and the first air guide block, and a driving structure for cooperating with the movable block is arranged on the support plate.

[0007] By adopting the above technical solution, when in use, the movable block is moved downward by the driving structure, thereby driving the connecting rod to be squeezed downward at the same time, and the connecting rod is rotatably connected to the connecting rod and the first air guide block. Therefore, when the connecting rod is squeezed downward, the first air guide block can be driven to move outward, and the first air guide block is slidably connected to the sliding rod, so that the first air guide block can slide outward on the sliding rod at the same time. At the same time, when the movable block moves downward, the movable rod and the piston block are squeezed downward at the same time, squeezing the gas in the air storage box and discharging it through the one-way air outlet, and then through the one-way air outlet and the first air guide block The air delivery hose between them allows the gas to be ejected from the first air guide block. After the gas enters the liquid, the liquid can be disturbed. The air contains a certain amount of oxygen, which can have a certain oxygenation effect on the pool body. Secondly, when the movable block moves upward, it drives the movable rod and the piston block to move upward at the same time. At this time, negative pressure is generated in the air storage box, and the outside air is drawn into the air storage box through the one-way air inlet to facilitate subsequent use. When the first air guide block slides in the pool body, the gas can be evenly filled into the pool body, thereby improving the practicality of the automatic oxygenation device for the entire larval pool.

[0008] The utility model is further configured as follows: the driving structure includes a motor, a belt, and a screw rod; the motor is fixed to the top of the support plate; the screw rod is fixedly connected to the output end of the motor; the screw rod movably passes through the support plate; the belt is located on the outside of the screw rod; an internal thread is opened in the movable block to cooperate with the screw rod.

[0009] By adopting the above technical solution, the motor, belt and screw rod cooperate with each other, so that the screw rod can rotate synchronously, thereby driving the movable block to slide up and down on the screw rod.

[0010] The utility model is further configured that limiting rods are symmetrically arranged on both sides of the support plate, and the limiting rods movably penetrate the movable block.

[0011] By adopting the above technical solution, the limit rod can limit the movable block and assist the screw rod so that the movable block can slide up and down flexibly outside the screw rod and the limit rod.

[0012] The utility model is further configured that a second air guide block is fixedly mounted on the slide bar, and the second air guide block is located in the middle of the first air guide block.

[0013] By adopting the above technical solution, when the second air guide block is located at the first air guide block, oxygen can be placed in the middle of the pool body, and the middle of the pool body can be oxygenated, so that the young shrimp can grow better.

[0014] The utility model is further configured that an air guide pipe is provided at the bottom of the pool body, the air guide pipes are in a mutually crossed state, and nozzles are provided on the air guide pipe, the first air guide block and the second air guide block.

[0015] By adopting the above technical solution, when the air guide pipes are arranged in a cross-state, oxygen can be better filled into the pool body through the cooperation between the nozzle, the air guide pipes, the first air guide block and the second air guide block.

[0016] The utility model is further configured such that an aerator used in conjunction with the air guide pipe and the second air guide block is provided on the support plate, a gas supply hose is connected between the second air guide block and the aerator, and a gas supply hose is provided between the air guide pipe and the aerator.

[0017] By adopting the above technical solution, the cooperation between the oxygenator and the gas delivery hose can enable oxygen to enter the pool body through the air guide pipe and the second air guide block, thereby achieving a better oxygenation effect.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] The utility model uses a driving structure to make the movable block move downward, thereby driving the connecting rod to be squeezed downward at the same time, and the connecting rod is rotatably connected with the connecting rod and the first gas guide block. Therefore, when the connecting rod is squeezed downward, the first gas guide block can be driven to move outward, and the first gas guide block is slidably connected with the sliding rod, so that the first gas guide block can slide outward on the sliding rod at the same time. At the same time, when the movable block moves downward, the movable rod and the piston block are squeezed downward at the same time, so that the gas in the gas storage box is squeezed and discharged through the one-way gas outlet, and then the gas is discharged through the one-way gas outlet and the gas transmission between the first gas guide block. The hose allows the gas to be ejected from the first air guide block. After the gas enters the liquid, the liquid can be disturbed. The air contains a certain amount of oxygen, which can have a certain oxygenation effect on the pool body. Secondly, when the movable block moves upward, it drives the movable rod and the piston block to move upward at the same time. At this time, negative pressure is generated in the air storage box, and the outside air is drawn into the air storage box through the one-way air inlet to facilitate subsequent use. When the first air guide block slides in the pool body, the gas can be evenly filled into the pool body, thereby improving the practicality of the automatic oxygenation device for the entire larval pool.
