Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an aerator for aquaculture ponds. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to finished aquatic product under artificial feeding and management. In a broader sense, it can also include aquatic resource enhancement. Aquaculture includes extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves releasing seedlings into small to medium-sized natural water bodies and relying entirely on natural feed to raise aquatic products, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as pond fish farming, net cage fish farming, and enclosure aquaculture. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation, and feeding high-quality feed to achieve high yields in small bodies of water, such as high-density flowing water fish and shrimp farming. Aeration of the water body is necessary during aquaculture.

[0003] For example, Chinese Patent (CN218681306U) discloses an aeration device for aquaculture ponds, relating to the field of aquaculture pond technology. The device includes a float plate, with a water tank fixedly connected to the top of the float plate. An aeration mechanism is movably inserted into the middle of the water tank. A water pump is fixedly connected to the top right side of the water tank. A water inlet pipe is fixedly connected to the water pump, and a water outlet pipe is fixedly connected to the water pump. A right-side protective pipe is fitted over the water inlet pipe. The aeration mechanism includes a rotating shaft and two baffles. A water wheel is fitted over the outer side of the middle of the rotating shaft, and water wheel blades are fixedly connected at equal intervals over the outer side of the water wheel. Rotary wheels are fitted over the outer sides of both the front and back of the rotating shaft. Sponge strips are connected to the rotating wheels. This device utilizes water pumped out by the water pump to continuously rotate the sponge strips, repeatedly causing the water on the inner wall of the water tank to turn into water droplets and come into contact with the air, greatly increasing the contact time between the water flow and the air, resulting in high aeration efficiency.

[0004] The above solution also has the following technical shortcomings: the oxygen dissolution efficiency is low. The above solution uses a sponge strip to absorb water and then impacts a baffle. The water droplets after the impact dissolve oxygen, which means that the oxygen dissolution efficiency is affected by the size of the sponge. Since the sponge itself is not large, its water absorption is quite limited, resulting in low efficiency of water droplet oxygen dissolution. Based on this, an aerator for aquaculture ponds is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aerator for aquaculture ponds, which has the advantages of conveniently improving the efficiency of dissolved oxygen in water and solving the problem that the water dissolution efficiency is limited by the size of the sponge.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aerator for aquaculture ponds, comprising a floating plate, an oxygen dissolving tank fixed to the top of the floating plate, an oxygen dissolving mechanism provided on the oxygen dissolving tank, an oxygen supply mechanism provided on the floating plate, a water supply mechanism provided on the floating plate and the oxygen dissolving mechanism, a water outlet pipe fixed to the bottom of the oxygen dissolving tank, and an iron anchor fixed to the bottom of the floating plate.

[0007] The dissolved oxygen mechanism includes a mounting box fixed to the right side of the dissolved oxygen tank. A motor is fixed to the right side of the inner wall of the mounting box. A first rotating shaft is fixed to the output shaft of the motor. The dissolved oxygen mechanism includes a second rotating shaft rotatably connected to the right side of the inner wall of the mounting box. A transmission assembly is provided on the outer surface of the first and second rotating shafts. Dissolved oxygen pipes are fixed on the outer surfaces of both the first and second rotating shafts. Multiple air outlets are provided on the dissolved oxygen pipes.

[0008] Furthermore, the oxygen supply mechanism includes an air pump fixed to the top of the floating plate, an air outlet pipe fixed to the output end of the air pump, two oxygen supply pipes fixed to one side of the air outlet pipe, a rotary joint fixed to the left end of the oxygen supply pipe, and a support frame fixed to the left end of the dissolved oxygen tank. The oxygen supply mechanism also includes a support frame fixed to the left end of the dissolved oxygen tank, an air inlet pipe fixed to the input end of the air pump, and an air intake head fixed to the end of the air inlet pipe away from the air pump.

[0009] Furthermore, the water supply mechanism includes a water inlet pipe fixed inside the floating plate, a water pump fixed at one end of the water inlet pipe, a water supply pipe fixed at the output end of the water pump, and multiple nozzles fixed on one side of the water supply pipe.

[0010] Furthermore, the transmission assembly includes a driving wheel fixed to the outer surface of the first rotating shaft, a driven wheel fixed to the outer surface of the second rotating shaft, and a transmission belt that is drively connected to the outer surfaces of the driving wheel and the driven wheel.

[0011] Furthermore, the left end of the second rotating shaft is rotatably connected to the right end of the inner wall of the mounting box, and the two sets of dissolved oxygen tubes are arranged alternately.

[0012] Furthermore, the left ends of the first and second rotating shafts are respectively rotatably connected to two rotary joints, and the outer surface of the rotary joints is fixed to the inner wall of the support frame.

[0013] Furthermore, the right end of the mounting box is fixed to the left end of the water pump, and the outer surfaces of both oxygen supply pipes are fixed to the left end of the dissolved oxygen tank.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The aquaculture pond uses an aerator. By installing an oxygen dissolving mechanism on the dissolved oxygen tank, oxygen is dispersed through dissolved oxygen pipes, thereby increasing the contact area between the gas and the water. At the same time, the dissolved oxygen pipes can stir the water and oxygen, further increasing the oxygen dissolution rate. By installing an oxygen supply mechanism on the floating plate, oxygen can be supplied to the inside of the dissolved oxygen tank, thereby maintaining sufficient oxygen in the dissolved oxygen tank, which is conducive to the combination of water and oxygen.
