Description

Technical Field

[0001] This utility model relates to the field of shrimp and crab farming technology, and in particular to a high-efficiency oxygenation device for shrimp and crab farming. Background Technology

[0002] High-efficiency aeration devices in shrimp and crab farming are designed to ensure a sufficient supply of dissolved oxygen in the aquaculture water. High-efficiency aeration can increase the dissolved oxygen level in the water, effectively promoting the growth of shrimp and crabs, improving their immunity, and preventing mortality or disease caused by oxygen deficiency. Common aeration devices include aerators, oxygenation pipes, dissolved oxygen equipment, microbubble aeration systems, and waterwheel aeration devices.

[0003] Most aerators work by installing an air pump on the shore and then connecting an air supply pipe to the inside of the aquaculture pond. This forces air or pure oxygen into the water, dissolving the oxygen in the air and increasing the oxygen content in the water. In traditional technology, the air supply pipe is usually fixed to the air pump with wire or clips. Over time, this can cause the connection to loosen, affecting oxygen delivery.

[0004] In existing technologies, the gas supply pipes of high-efficiency oxygenation devices for shrimp and crab farming are mostly connected to the air pump by sleeves or snap-fit ​​connections. Over time, these connections may loosen and fall off, reducing the efficiency of oxygen delivery and the practicality of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency oxygenation device for shrimp and crab farming, which aims to improve the problem.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency oxygenation device for shrimp and crab farming, comprising a base, a drive motor fixedly connected to the top of the base, an aerator fixedly connected to the output end of the drive motor, a connecting pipe fixedly connected to the output end of the aerator, a connector slidably connected to the side of the connecting pipe away from the aerator, a slot provided on the outside of the connector, an air supply pipe fixedly connected inside the connector, a dustproof net fixedly connected to the input end of the drive motor, a connecting mechanism provided inside the connecting pipe for quickly installing or removing the air supply pipe, and a cleaning mechanism provided on the side of the dustproof net away from the drive motor for cleaning the floating dust on the outside of the dustproof net to prevent blockage.

[0007] As a further description of the above technical solution:

[0008] A sealing ring is fixedly connected to the outside of the connector, and the sealing ring abuts against the side of the connecting pipe away from the aerator.

[0009] As a further description of the above technical solution:

[0010] The connecting mechanism includes a slide rod slidably connected to the top of the connecting tube. A slider is fixedly connected to the bottom of the connecting tube, and a return spring is fixedly connected to the bottom of the slider. Connecting rods are rotatably connected to both sides of the slider. U-shaped frames are rotatably connected to the bottom of both connecting rods. Locking rods are fixedly connected to the bottom of both U-shaped frames. Clamps are fixedly connected to the opposite sides of both locking rods, and both clamps engage with the locking groove.

[0011] As a further description of the above technical solution:

[0012] The slider is slidably connected inside the connecting tube, and both connecting rods are slidably connected inside the connecting tube.

[0013] As a further description of the above technical solution:

[0014] The bottom of the return spring is fixedly connected to the inside of the connecting tube.

[0015] As a further description of the above technical solution:

[0016] A handle is fixedly connected to the top of the slide bar.

[0017] As a further description of the above technical solution:

[0018] The cleaning mechanism includes a connecting rod, which is fixedly connected to the input end of the drive motor. A mounting shell is fixedly connected to the side of the connecting rod away from the drive motor. A plurality of compression springs are fixedly connected inside the mounting shell. A limit plate is fixedly connected to the side of the compression springs near the drive motor. A compression plate is fixedly connected to the side of the limit plate away from the compression springs. A brush is fixedly connected to the side of the compression plate away from the limit plate. The side of the brush away from the compression plate abuts against the side of the dustproof net away from the drive motor.

[0019] As a further description of the above technical solution:

[0020] The limiting plate is slidably connected inside the mounting shell, and the extrusion plate penetrates the mounting shell on the side near the dustproof net.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, pushing the slider downwards with the handle causes the slider to move downwards, compressing the return spring. When the slider moves downwards, two connecting rods drive two U-shaped brackets, causing two clamps to separate relative to each other, releasing the engagement with the slot. This allows the gas supply pipe to be removed along with the connector. After replacing the gas supply pipe with a new one, it is reinserted into the connecting pipe. Releasing the handle causes the slider to move upwards under the push of the return spring, allowing the two clamps to re-engage with the slot and secure themselves. This achieves the effect of more convenient and faster installation or removal of the gas supply pipe through the connecting mechanism, enabling more timely replacement of damaged gas supply pipes, improving the efficiency of oxygen delivery, and enhancing the practicality of the device.

[0023] 2. In this utility model, the drive motor needs to continuously ventilate and dissipate heat during equipment operation. The dustproof net can effectively prevent dust from entering the drive motor and causing it to run obstructed. When the drive motor is running, it drives the mounting shell to make a circular motion on the outside of the dustproof net through the connecting rod. The compression spring in the mounting shell provides elasticity, which, through the limiting plate, makes the compression plate push the brush to always stick to the surface of the dustproof net for automatic cleaning, preventing dust from accumulating on the dustproof net. This achieves the effect of automatically cleaning the surface dust of the dustproof net through the cleaning mechanism, preventing dust from entering the drive motor through the dustproof net and affecting its operation, enhancing the efficiency of oxygen delivery, and improving the practicality of the device.
