Description

Technical Field

[0001] The utility model relates to the technical field of river crab breeding, in particular to an oxygenator for river crab breeding. Background Art

[0002] River crab is an important freshwater crab with tender meat, delicious taste and rich nutrition. River crab has strong adaptability, wide breeding range and rapidly increasing breeding scale, which brings good economic benefits to farmers. In the breeding process of river crab, the use of oxygenator plays an important role in improving the yield and quality of river crab. Among them, the "aerator" disclosed by the application number "CN216533324U" has solved the various disadvantages of the existing aerator, that is, the diffusion range of oxygen dissolved in water is very small and the effect is not ideal. After further search, it is found that the "aerator" disclosed by the application number "CN213281183U" has a specific technical structure setting. The invention effectively solves the technical disadvantages that the shell of the blower mechanism of the existing aerator is mostly an integrated structure, and when the shell is corroded, it often needs to be replaced as a whole, and the maintenance cost is high. However, in actual use, aerators for river crab farming with similar structures still have many defects, such as: the blades of most aerators are directly welded and fixed, and the blades will be damaged after long-term use, which affects the oxygenation effect, and it is inconvenient to replace and maintain the blades separately, which reduces the use effect. At the same time, most aerators are used by floating on the water surface, and there is no protective structure around the blades, which will cause the crabs to be easily injured when they are close to the blades, reducing the safety effect. Therefore, it is necessary to design an aerator for river crab farming. Utility Model Content

[0003] The purpose of the utility model is to provide an oxygenator for river crab farming to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aerator for river crab farming, comprising a fixed seat, a first fixed ring and a base, a motor is fixedly installed on the top of the base, a turntable is rotatably installed on the bottom of the base, a fixing clamp is fixedly installed on the outside of the turntable, a paddle blade is clamped and fixed on the inside of the fixing clamp, a first fixing ring is fixedly installed on the bottom of the base outside the paddle blade, a second fixing ring is fixedly connected to the bottom of the first fixing ring, a first protective net is fixedly connected between the first fixing ring and the second fixing ring, a fixed seat is fixedly installed on the outside of the base, and a float is fixedly connected to the bottom of the fixed seat.

[0005] The buoyancy generated by the float can make the device float on the water surface, the motor can drive the turntable to rotate, and the paddle blades can be driven to rotate synchronously, so as to generate waves on the water surface, which can be combined with oxygen in the air to perform oxygenation operations in the water pool. By inserting the paddle blades into the fixing clips, the paddle blades can be easily fixed and the paddle blades can be easily disassembled separately, so that they can be replaced independently after being damaged. The first protective net can prevent river crabs from getting close to the paddle blades and causing damage, thereby reducing the losses caused by the death of river crabs.

[0006] Preferably, a protective box is fixedly installed on the top of the base outside the motor, and heat dissipation holes are opened on both sides of the protective box. The protective box can conveniently protect the motor to prevent the motor from being damaged, and the heat dissipation holes can facilitate the motor to dissipate heat to prevent the motor from overheating and affecting its operation.

[0007] Preferably, the base and the turntable are rotatably mounted via a rotating rod, and the rotating rod is fixedly connected to the output end of the motor. The motor can drive the rotating rod to rotate, and can synchronously drive the turntable to rotate.

[0008] Preferably, the rotating disk and the fixing clamp are fixedly installed via a support rod, and the fixing clamp and the blade are fixed via a fixing bolt. The fixing bolt can be used to conveniently fix the blade.

[0009] Preferably, the surface of the blade is provided with through grooves, and the through grooves are evenly spaced. The through grooves can reduce the resistance of the blade during rotation, and at the same time can increase the number of water splashes, thereby improving the oxygenation effect.

[0010] Preferably, the base and the first fixing ring are fixedly installed via a fixing frame, and the first fixing ring and the second fixing ring are fixedly installed via a fixing column. The fixing frame can conveniently fix the first fixing ring to avoid shaking, and the fixing column can conveniently connect the first fixing ring and the second fixing ring, while improving the structural strength.

[0011] Preferably, the base and the fixing seat are fixedly installed by a fixing rod, and a counterweight is fixedly installed at the bottom of the float. The counterweight can increase the gravity effect, so that the float is not easily shaken by the waves on the water surface.

[0012] Preferably, a second protective net is fixedly mounted on the bottom of the second fixing ring, and the second protective net and the first protective net are made of metal nets, which can effectively prevent the second protective net and the first protective net from being damaged and increase their service life.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By providing the fixing clip, the fixing bolt and the blade, the blade can be inserted into the fixing clip to fix the blade. It is also convenient to disassemble the blade separately and replace the blade independently after it is damaged, which can reduce maintenance costs and effectively avoid the impact on the oxygenation operation.

[0015] 2. By providing the first fixing ring, the second fixing ring and the first protective net to cooperate with each other, a protective cover effect can be formed on the outside of the blade, which can prevent river crabs from getting close to the blades and causing damage, and can reduce the losses caused by the death of river crabs. At the same time, it does not affect the rotation of the blades for oxygenation operations, and effectively improves the safety effect during use. BRIEF DESCRIPTION OF THE DRAWINGS
