Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and more specifically refers to an aeration device suitable for aquaculture ponds with different water body heights. Background Art

[0002] In aquaculture, water quality is one of the most critical factors in aquaculture, and dissolved oxygen is an important indicator of water quality. The main method to increase the dissolved oxygen content in aquaculture water is aeration.

[0003] At present, in factory-scale breeding workshops, the existing aeration and oxygenation methods mostly use blast aeration devices, that is, the air is filled to the bottom of the breeding water body through the blower through the inflation pipe and the air stone connected thereto, so that the air contacts the water more during the rising process of the lower water body, thereby increasing the dissolved oxygen concentration in the water body. However, since the air stones occupy a lot of space in the water body, and each air stone needs to be equipped with an inflation pipe, the air stone is only effective in oxygenating the water body in the vertical direction when it is inflated, and the oxygenation efficiency is not high.

[0004] To solve the above problems, a Chinese utility model patent with authorization publication number CN 202456114U discloses an aquaculture pond with a nano aeration tube, including a culture pond respectively provided with an inlet pipe and a drain pipe. In order to make the water in the culture pond fully aerated and have a good dissolved oxygen concentration, a nano aeration tube connected to a Roots blower is provided at the bottom of the culture pond.

[0005] However, in reality, each nano aeration tube only has a good aeration and oxygenation effect within a certain depth range of the aquaculture pond, and the water height of the aquaculture pond varies greatly depending on the number or species of fish being cultured. Therefore, simply arranging multiple nano aeration tubes at the bottom of the aquaculture pond is difficult to meet the aeration and oxygenation needs of aquaculture ponds with different water heights. Utility Model Content

[0006] The utility model provides an aeration device suitable for aquaculture ponds with different water body heights, so as to solve the problem that the existing aquaculture ponds only have nano aeration pipes arranged at the bottom, which is difficult to meet the aeration and oxygenation requirements of aquaculture ponds with different water body heights.

[0007] The utility model adopts the following technical solutions:

[0008] An aeration device suitable for aquaculture ponds with different water body heights, comprising an air intake main pipe and several groups of nano aeration pipes, wherein the air intake main pipe is arranged along the top edge of an aquaculture pond, the air intake main pipe is provided with at least two air inlets, two air intake branches connected to the air intake main pipe are respectively fixed to each side wall of the aquaculture pond, a group of nano aeration pipes are connected between the two air intake branches of each side wall, each group of nano aeration pipes comprises several nano aeration pipes arranged in parallel and spaced apart from each other, the two ends of each nano aeration pipe are respectively connected to the corresponding air intake branch pipe, and each nano aeration pipe is provided with an aeration pipe control valve, and each nano aeration pipe is densely covered with a plurality of aeration holes.

[0009] In a preferred embodiment, an air inlet is respectively provided at both ends of the air inlet main pipe, and an air inlet valve is respectively installed on the air inlet main pipe at each air inlet.

[0010] In a preferred embodiment, each group of nano aeration tubes includes 3-5 nano aeration tubes arranged at equal intervals in the vertical direction.

[0011] In a preferred embodiment, the height distance between two adjacent nano aeration tubes in each group of nano aeration tubes is 20-30 cm, and the distance between the bottom nano aeration tube and the bottom of the aquaculture pond is 10-20 cm.

[0012] In a preferred embodiment, a drainage port is provided at the bottom center of the aquaculture pond, and each group of nano aeration tubes is biased toward the same side of the side wall of the corresponding aquaculture pond.

[0013] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0014] 1. The aeration device of this structure is provided with a group of nano aeration tubes on each side wall of the aquaculture pond, each group of nano aeration tubes includes a number of nano aeration tubes arranged in parallel and spaced apart from each other, and both ends of each nano aeration tube connected to the air inlet branch pipe are provided with aeration tube control valves. When the water height in the aquaculture pond exceeds a certain nano aeration tube, the aeration tube control valves on the nano aeration tube and all the nano aeration tubes below it can be opened to fully aerate the water in the aquaculture pond, increase the dissolved oxygen concentration of the water, and make the dissolved oxygen content in the water meet the needs of the fry. Therefore, the nano aeration device of the utility model can adapt to the aeration and oxygenation needs of aquaculture ponds with different water heights by controlling the aeration tube control valves of each nano aeration tube on each side wall.

[0015] 2. The aeration device of this structure has air inlets at both ends of the air intake main pipe, and both ends of each nano aeration tube on each group of nano aeration tubes are connected to air intake branches, so that both ends of the air intake main pipe and both ends of each nano aeration tube can be simultaneously aired, which greatly reduces the uneven air intake caused by the excessive length of the nano aeration tubes and improves the uniformity of water aeration in the aquaculture pond.

[0016] 3. In the aeration device of this structure, each group of nano aeration tubes is biased towards the same side of the side wall of the corresponding aquaculture pond. When the groups of nano aeration tubes aerate at the same time, the water in the aquaculture pond can form a circulation structure, accelerate the flow of the water body, and then improve the aeration and oxygenation efficiency of the water body. At the same time, the water in the aquaculture pond forms a nest flow to gather the sediment in the middle, which is convenient for sewage discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details. For well-known components, methods and processes, they are not described in detail below.

[0020] An aeration device suitable for aquaculture ponds with different water heights, refer to Figure 1 and Figure 2 , including an air intake main pipe 20 and a plurality of groups of nano aeration tubes. The air intake main pipe 20 is arranged along the top edge of the aquaculture pond. The aquaculture pond 1 has a water inlet (not shown in the figure), which can be installed in the middle and upper part or above the aquaculture pond. A water outlet 11 is provided at the bottom center of the aquaculture pond 1. Two air intake branches 30 connected to the air intake main pipe 20 are fixed on each side wall of the aquaculture pond 1, and the air intake main pipe 20 is connected to each air intake branch pipe 30 through a tee 201.

[0021] Reference Figure 1The air intake main pipe 20 forms a ring structure with a gap at the top edge of the aquaculture pond, and at least one air inlet 21 is provided at the gap. In this embodiment, an air inlet 21 is provided at both ends of the gap, and an air inlet valve 22 is installed at each air inlet 21. The air intake main pipe 20 is provided with air inlets 21 at both ends, and gas is introduced from the two air inlets 21, which can reduce the difference between the gas intake amount at the rear end and the gas intake amount at the front end due to the excessive length of the air intake main pipe 20, thereby causing uneven aeration.

[0022] Reference Figure 1 and Figure 2 A group of nano aeration tubes is connected between the two air inlet branches 30 on the side wall of each aquaculture pond. Each group of nano aeration tubes includes a plurality of nano aeration tubes 41 arranged in parallel and spaced apart from each other, preferably 3-5 nano aeration tubes 41 arranged at equal intervals in the vertical direction.

[0023] Reference Figure 2 In this embodiment, each group of nano aeration tubes 41 is specifically shown to have three nano aeration tubes, and the corresponding n-th nano aeration tubes on each group of nano aeration tubes 41 are on the same horizontal plane. For example, the first (i.e., the bottom layer) nano aeration tubes on each group of nano aeration tubes are on the same horizontal plane.

[0024] The height distance between two adjacent nano aeration tubes 41 in each group of nano aeration tubes 41 is 20-30 cm, and the distance between the bottom nano aeration tube 41 and the bottom of the aquaculture pond 1 is also 20-30 cm.

[0025] Reference Figure 2 Both ends of each nano aeration tube 41 are connected to the corresponding air inlet branch pipe 30 , and each is equipped with an aeration tube control valve 42 . Each nano aeration tube 41 is densely distributed with a plurality of aeration holes 410 .

[0026] Both ends of each nano aeration tube in each group of nano aeration tubes 41 are connected to air inlet branches 30, which can further reduce the uneven air intake caused by the excessive length of the nano aeration tubes 41 and improve the uniformity of water aeration in the aquaculture pond.

[0027] Each group of nano aeration tubes is biased toward the same side of the side wall of the corresponding aquaculture pond 1. In this embodiment, each group of nano aeration tubes is specifically arranged to be biased toward the right side of each side wall of the aquaculture pond 1, where the right side refers to the perspective from the inside of the aquaculture pond toward each side wall. In this design, when each group of nano aeration tubes aerates at the same time, the water in the aquaculture pond can form a circulation structure and flow out from the drainage port at the bottom center, which speeds up the flow of the water and thereby improves the aeration and oxygenation efficiency of the water.

[0028] The nano aeration device of the utility model can control the opening and closing of the aeration pipe control valve on each nano aeration pipe on each side wall according to the water height of the aquaculture pond, so that the water in the aquaculture pond is fully aerated, the dissolved oxygen concentration of the water is increased, and the dissolved oxygen content in the water meets the needs of fry.

[0029] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
