Description

Technical Field

[0001] The utility model relates to the technical field of crayfish farming, in particular to an oxygen-increasing device for crayfish farming. Background Technique

[0002] During the crayfish farming process, in order to avoid the death of crayfish caused by insufficient oxygen content in the water body, an oxygen-increasing device is usually used to increase the oxygen content in the water body. After retrieval, a patent with the authorization number of CN216415667U discloses an oxygen-increasing device for the water body of crayfish ecological farming. Although the device rotates the formed rotating water flow along the surface of the concave structure of the dispersing part in the same direction, continuously stirs the water flow, symmetric overflow holes are arranged on the surface of the dispersing part, and the dispersing part and the stirring part are installed in a vertical structure, so that the water flow on one side of the dispersing part and the water flow on one side of the stirring part collide to form water splashes, increasing the oxygen content in the water, but when the device increases the oxygen in the water, it can only increase the oxygen in the upper layer of the water body, and the water splashes generated by the collision of the water flow and the water flow on one side of the stirring part cannot reach the bottom of the water body, and the water surface of the water body has a large contact surface with the air. Compared with the upper layer of the water body, the bottom of the water body has less contact with the air and is usually more severely oxygen-deficient, which leads to insufficient oxygen content in the water body at the bottom of the pool, resulting in the situation that the crayfish at the bottom of the pool are still prone to hypoxia. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an oxygen-increasing device for crayfish farming, which solves the problem that the existing device in the background technology can only increase the oxygen in the upper layer of the water body, and the bottom of the water body will still be short of oxygen.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: an oxygen-increasing device for crayfish farming, including an air pump, a first connecting pipe, a connecting head, an aeration tank, a sliding plate and a slot. One end of the air pump is communicated with one end of the first connecting pipe, the other end of the first connecting pipe is communicated with one end of the top of the connecting head, one end of the bottom of the connecting head is communicated with one end of the top of the second connecting pipe, the other end of the bottom of the second connecting pipe is communicated with the inside of the aeration tank, a slot is arranged on the surface of the aeration tank, a sliding plate is arranged inside the slot, and the four ends of the bottom of the aeration tank are welded to one end of the top of the support rod, and one end of the bottom of the support rod is welded to the counterweight.

[0005] Preferably, there are two sliding plates, and fine holes are evenly distributed on the surfaces of the two sliding plates, and the sliding plates are respectively arranged at the top and bottom of the aeration tank. When air passes through the fine holes on the surface of the sliding plate, it can become dense bubbles, thereby increasing the contact surface with the water body at the bottom of the pool.

[0006] Preferably, two slots are provided. The inner parts of the two slots are in sliding contact with the surface of the skateboard. Two rectangular holes are provided at one end of the skateboard. The two skateboards can be slid out through the skateboard, which is beneficial to the disassembly of the skateboard, facilitating the cleaning of the surface holes and preventing blockage after long-term use, thus affecting the air outlet.

[0007] Preferably, a groove is provided on one side of the aeration tank. The cross-section of the groove is in a T-shaped structure, and a convex block is provided on the other side of the aeration tank. The shape of the convex block matches the shape of the inner part of the groove on one side of the aeration tank. By slidingly connecting the convex block on one side of two adjacent aeration tanks with the groove, it is beneficial to connect the two aeration tanks to each other, thereby increasing the aeration area at the bottom of the pool.

[0008] Preferably, one end of the first connecting pipe and the second connecting pipe are both threadedly connected to the connecting head. The outer walls of the first connecting pipe and the second connecting pipe are both corrugated, which is beneficial for the first connecting pipe and the second connecting pipe to expand and contract according to the depth of the water body.

[0009] Preferably, the connecting head is provided with four connection ports, and the internal channel is in a cross shape. The two ends of the connecting head are threadedly connected to the plug. By connecting the connecting head with a plurality of second connecting pipes, it is beneficial for the air pump to pump air into a plurality of aeration tanks simultaneously.

[0010] The utility model provides a crayfish breeding oxygenation device, which has the following beneficial effects:

[0011] (1) When the crayfish breeding oxygenation device is in use, by placing the aeration tank at the bottom of the pool, the bottom of the aeration tank is supported by the counterweight block and the support rod, so that there is a gap between the bottom of the aeration tank and the bottom of the pool. Then, the air pump pumps air into the aeration tank through the first connecting pipe and the second connecting pipe. After the air enters the aeration tank, it will pass through the hole slots on the surface of the skateboard at the top and bottom of the aeration tank, and then become dense bubbles rising from the bottom in the pool. This is beneficial for the device to fully oxygenate the bottom of the pool. At the same time, due to the gap between the bottom of the aeration tank and the bottom of the pool, bubbles can be ejected from both the top and bottom of the aeration tank, which is beneficial to increasing the oxygenation amount.

[0012] (2) For the crayfish breeding oxygenation device, by slidingly connecting the convex block on one side of two adjacent aeration tanks with the groove, it is beneficial to connect the two aeration tanks to each other. Then, the other ends of the second connecting pipes respectively connected to one end of the two aeration tanks are connected to the same connecting head, which is beneficial for the air pump to pump air into multiple groups of aeration tanks for oxygenation, thus improving the practicability of the device.

[0013] Therefore, the problem that the existing device can only oxygenate the upper layer of the water body while the bottom of the water body is still hypoxic is solved. Brief Description of the Drawings

Then, the air pump 1 pumps air into the aeration tank 5 through the first connecting pipe 2 and the second connecting pipe 4. After the air enters the aeration tank 5, it will pass through the pore grooves on the surface of the sliding plates 6 at the top and bottom of the aeration tank 5, and then become dense bubbles rising from the bottom in the pool. This is beneficial to enabling the device to fully oxygenate the bottom of the pool. At the same time, due to the gap between the bottom of the aeration tank 5 and the bottom of the pool, bubbles can be ejected from both the top and bottom of the aeration tank 5, which is beneficial to increasing the oxygenation amount. The two sliding plates 6 can be slid out through the sliding plates 6, which is beneficial to enabling the sliding plates 6 to be disassembled, thus facilitating the cleaning of the pore grooves on the surface and preventing blockage after long-term use, which affects the air outlet. By slidingly connecting the convex blocks on one side of two adjacent aeration tanks 5 with the grooves, it is beneficial to connect the two aeration tanks 5 to each other. Then, the other ends of the second connecting pipes 4 respectively connected to one end of the two aeration tanks 5 are connected to the same connector 3, which is beneficial to enabling the air pump 1 to pump air into multiple groups of aeration tanks 5 for oxygenation.
