Description

Technical Field

[0001] The invention belongs to the technical field of scientific breeding and relates to an aeration device, in particular to an aeration device suitable for a "U"-shaped breeding pond and an installation method thereof. Background Art

[0002] In recent years, my country's aquaculture industry has developed rapidly. In 2018, the total output of aquaculture in my country exceeded 50 million tons, accounting for more than 78% of the total output of aquatic products in China. China is the only fishing country in the world where the total amount of farmed aquatic products exceeds the total amount of fishing. Aquaculture has become one of the fastest-growing agricultural industries. In order to promote the development of traditional aquaculture models to efficient modern fisheries and improve the output and quality of aquaculture products, a series of methods to increase aquaculture density, such as aeration and oxygenation, microbial agents, etc., have been used in inland and coastal aquaculture areas. Aeration and oxygenation have become the standard for efficient aquaculture. It can keep the dissolved oxygen in the pond water stable and reach an aerobic state, which can maximize the increase in aquaculture density, shorten the aquaculture cycle, and increase the output of aquatic products. At present, aeration devices used in aquaculture ponds are generally set up on the shore. However, with the change of aquaculture methods, such as the large-scale promotion of the mixed culture mode of shrimp, crab and fish, "U"-shaped aquaculture ponds have appeared. The existing aeration layout method is obviously not applicable to this "U"-shaped aquaculture pond. For example, arranging the aeration main pipe on the shore is not convenient for daily pond maintenance and management, and also increases the cost of aeration installation, which does not achieve the purpose of aeration balance of dissolved oxygen in the aquaculture pond. Therefore, for the "U"-shaped aquaculture pond, it is very necessary to design an aeration layout method to solve the aeration oxygenation problem, which is very necessary to increase the output of aquatic products in the "U"-shaped aquaculture pond. Summary of the invention

[0003] In order to solve the technical problem that traditional aeration arrangement is no longer suitable for "U"-shaped aquaculture ponds, the present invention provides an aeration device for "U"-shaped aquaculture ponds and an installation method thereof, which solves the problems existing in the above-mentioned existing aeration devices in actual projects and has been put into practical application.

[0004] The specific technical solution adopted by the present invention to solve its technical problem is:

[0005] The invention provides an aeration device for a "U"-shaped breeding pond, comprising an aeration main unit, an aeration main pipe, a plurality of aeration branch pipes and a plurality of aeration discs. The aeration main unit is arranged on the bank of the "U"-shaped breeding pond, generally placed in the middle of the bank of the breeding pond, and adjusted in special cases according to the power supply position and pond conditions; the aeration main pipe is connected to the air outlet end of the aeration main unit, the aeration main pipe is arranged on the water surface of the return ditch of the "U"-shaped breeding pond, and is closed and arranged along the inner edge of the return ditch of the "U"-shaped breeding pond for a circle; the plurality of aeration branch pipes are arranged on the aeration main unit at equal intervals, the air outlet end of the aeration branch pipe is connected to the aeration disc, and a water distribution saddle and an external thread ball valve are provided at the connection between each of the aeration branch pipes and the aeration main pipe, and the opening and closing of a single corresponding aeration disc are controlled by the external thread ball valve.

[0006] Preferably, the aeration main pipe is a PE pipe, and the diameter of the PE pipe is 40 cm or 50 cm, which has the advantage of good pressure resistance and can withstand a pressure of 0.6 MPa, which can meet the ventilation requirements of the aeration main unit; further, fixed bamboo poles are respectively provided on both sides of the aeration main pipe, and the two fixed bamboo poles are connected by a cable tie, and the two fixed bamboo poles are arranged 30 cm above the water surface, which plays the role of fixing the PE pipe on the water surface. However, if there is an inner net in the return ditch pond itself, the inner net can be used for fixing, depending on the actual situation. The length of the fixed bamboo pole depends on the circumference of the pond, and it floats on the water surface and floats up and down with the water level.

[0007] Preferably, the aeration main pipes of the aeration main unit are connected by a three-way connection, and the three-way connection is also made of PE material. Furthermore, a check valve is provided at the air outlet of the aeration main unit to prevent the backflow of water in special circumstances, thereby protecting the aeration main unit.

[0008] Preferably, each of the aeration pipes and the aeration plate is connected with a pipe clamp to tighten the aeration pipe to prevent air and water leakage. Further, the aeration pipe is a double-layer steel wire braided hose, and the inner diameter of the aeration pipe is 10 cm. The aeration pipe can sink into the water by itself, and has a strong hardness, which can avoid being bitten off by shrimps and crabs, and can be used in shrimp and crab ponds.

[0009] Preferably, each aeration plate is connected to a steel wire rope, and the other end of the steel wire rope is connected to a floating ball serving as an identifier. The floating ball floats on the water surface to mark the position of the aeration plate, facilitating subsequent daily maintenance.

[0010] Preferably, the aeration disc is a diamond aeration disc with a check valve, the aeration disc is a circular or square structure, the corresponding diameter or side length is 200mm to 300mm, and the aperture of the aeration disc is 150 mesh to 1000 mesh.

[0011] At the same time, the present invention also provides an installation method of the above-mentioned aeration device, wherein the installation of the aeration device is to set the aeration main unit on the bank of the "U"-shaped breeding pond, and to close the aeration main pipe along the inner edge of the return ditch of the "U"-shaped breeding pond. The specific installation process is as follows:

[0012] S1, surveying the basic conditions of the U-shaped breeding pond and selecting the technical parameters of the aeration device according to the survey results;

[0013] S2, according to the basic situation of the "U"-shaped breeding pond and the location of the power supply, select the installation location of the aeration host and install it;

[0014] S3, installing an aeration main pipe, closing the aeration main pipe around the inner edge of the return ditch of the "U"-shaped breeding pond to form an "U"-shaped aeration main pipe, and setting a fixed bamboo pole for fixing the aeration main pipe on both sides of the aeration main pipe, and connecting the two bamboo poles together with a cable tie;

[0015] S4, connecting the aeration main unit and the aeration main pipe, and setting a check valve at the air outlet of the aeration main unit;

[0016] S5. Install the aeration branch pipes on the U-shaped aeration main pipe through the water distribution saddle opening according to the designed return groove position of the aeration plate, and install an external thread ball valve on each aeration branch pipe, then connect the aeration plate to the aeration branch pipe and tighten it with a pipe clamp;

[0017] S6, connect one end of the wire rope to the aeration plate, and the other end to the float, and expose the float on the water surface to serve as a mark, and then the aeration device is installed.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The aeration device and installation method for a "U"-shaped breeding pond provided by the present invention are improvements made on the basis of the existing aeration arrangement mode in view of the characteristics of the "U"-shaped breeding pond being shallow in the middle and deep around. The aeration device and installation method have been applied in actual projects and achieved good results: firstly, the present invention arranges the aeration main pipe on the water surface of the inner edge of the "return ditch". Such an arrangement does not occupy the position of the pond bank and does not affect the use of the land on the pond bank, thus solving the problem of damaging the aeration main pipe when large equipment such as excavators dig the "return ditch" in the future. This point has the most prominent effect on the use of the aeration installation of the "U"-shaped pond; secondly, the present invention arranges the aeration main pipe along the inner edge of the return ditch of the "U"-shaped breeding pond. The closed arrangement is arranged for one circle, so that the installation cost can be reduced, and the circumference of the entire aeration main pipe is reduced, which can reduce the cost of the aeration main pipe and other expenses; thirdly, the aeration main pipe of the present invention is made of PE material, which has good safety and high cost performance, and a check valve is arranged at the air outlet end of the aeration main pipe and a diamond aeration disk with a built-in check valve is used, which can avoid water backflow to the greatest extent and protect the main machine; finally, the aeration device and installation precautions of the present invention solve the problems of installation and later management during the installation of aeration in some aquaculture ponds, and can also be transformed into a conventional installation method around the pond according to the specific conditions of the aquaculture pond, which has the advantage of flexible use.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] like Figure 1-2 As shown, this embodiment provides an aeration device for a "U"-shaped breeding pond, which mainly includes an aeration main unit 1, an aeration main pipe 2, a plurality of aeration branch pipes 3 and a plurality of aeration plates 4, wherein:

[0026] In view of the characteristics of the "U"-shaped breeding pond being shallow in the middle and deep around, the aeration main unit 1 is arranged on the bank of the breeding pond, generally placed in the middle position of the outer edge 13 (bank) of the breeding pond return ditch. In special cases, the position can be flexibly adjusted according to the power supply position and the breeding pond conditions.

[0027] The aeration main pipe 2 is connected to the air outlet end of the aeration main unit 1, and the aeration main pipe is diverted to the left and right by connecting the tee 15. Further, the diverted aeration main pipe 2 is arranged on the water surface of the return ditch of the "U"-shaped breeding pond, and is closed and arranged along the inner edge 12 of the return ditch of the "U"-shaped breeding pond. Fixed bamboo poles 7 are respectively provided on both sides of the aeration main pipe 2. The two fixed bamboo poles 7 are connected by a cable tie, and the two fixed bamboo poles 7 are arranged 30 cm above the water surface, which can play a role in fixing the aeration main pipe 2 on the water surface. However, if the return ditch pond itself has an inner net, the inner net can be used to fix the aeration main pipe 2 without the need for fixed bamboo poles 7. The specific situation can be determined according to the actual project situation. The length of the fixed bamboo poles 7 is determined according to the circumference of the breeding pond. It floats on the water surface and floats up and down with the water level.

[0028] Specifically, the aeration main pipe 2 is a PE pipe, and the diameter of the PE pipe is 40 cm or 50 cm. The material of this specification has the characteristic of good pressure resistance, and its pressure bearing capacity is 0.6 MPa, which can meet the ventilation requirements of the aeration main unit 1.

[0029] Specifically, a check valve 8 is provided at the air outlet of the aeration main unit 1 to prevent the backflow of water under special circumstances, thereby protecting the aeration main unit 1 .

[0030] The multiple aeration branch pipes 3 are arranged at equal intervals on the "U"-shaped aeration main pipe 2, and a water distribution saddle 5 and an external thread ball valve 6 are arranged at the connection between each aeration branch pipe 3 and the aeration main pipe 2. The diameter size of the PE pipe of the water distribution saddle 5 is consistent, and the external thread ball valve 6 is mainly arranged to realize the function of opening and closing a single aeration plate 4.

[0031] Furthermore, an aeration plate 4 is connected to the other end of each aeration branch pipe 3, and the aeration plate 4 is a diamond aeration plate with a check valve, and the check valve is installed on the air outlet of the diamond aeration plate, which can avoid water backflow to the greatest extent and protect the aeration main unit 1; preferably, the aeration plate 4 is a circular or square structure, and its corresponding diameter or side length is 200mm~300mm, and its aperture is 150 mesh~1000 mesh.

[0032] Further preferably, the connection between the aeration branch pipe 3 and the aeration plate 4 is tightened with a pipe clamp 9 to avoid water leakage. The aeration branch pipe 3 adopts a double-layer steel wire braided hose, and the inner diameter of the aeration branch pipe 3 is 10 cm. The aeration branch pipe 3 can sink in water by itself and has the advantage of strong hardness, which can avoid being bitten off by shrimps and crabs, and can be used in shrimp and crab breeding ponds.

[0033] Specifically, a steel wire rope 10 is connected to each aeration plate 4, and the other end of the steel wire rope 10 is connected to a float 11. The float 11 floats on the water surface 14 and can mark the position of the aeration plate 4, which is convenient for subsequent daily maintenance.

[0034] In addition, the specific installation process of an aeration device for a "U"-shaped breeding pond provided in this embodiment is as follows:

[0035] S1, first, survey the basic conditions of the "U"-shaped aquaculture pond to understand its water depth, area, length and width, whether it is an intensive aquaculture pond or a polyculture pond, the width of the return ditch, etc., and select the power of the aeration main unit 1 of the aeration device, the length of the aeration main pipe 2, the number of aeration discs 4 and other technical parameters of auxiliary materials according to the survey results, and transport them to the bank of the aquaculture pond;

[0036] S2, secondly, according to the basic situation of the "U"-shaped breeding pond and the location of the power supply, the installation position of the aeration host 1 is selected. The installation position is set at the bank of the breeding pond, generally installed in the middle of the bank. In actual engineering, the location of the power supply should be taken into consideration and it should be installed near the location of the power supply as much as possible;

[0037] S3, then install the aeration main pipe 2, and arrange the aeration main pipe 2 along the inner edge 12 of the return ditch of the "U"-shaped breeding pond to form a "U"-shaped aeration main pipe, and install the fixed bamboo pole 7 according to whether the breeding pond has an inner net. If there is an inner net, the aeration main pipe 2 can be directly fixed with the inner net. If there is no inner net, two bamboo poles 7 are set on both sides of the aeration main pipe 2, and the two fixed bamboo poles 7 are connected with a cable tie. The two fixed bamboo poles 7 are set 30 cm above the water surface to fix the aeration main pipe 2, and can also float up and down with the water surface.

[0038] S4, connecting the aeration main unit 1 and the aeration main pipe 2, connecting the aeration main pipe 2 to the air outlet end of the aeration main unit 1, and setting a check valve 8 to prevent water backflow, and connecting the aeration main pipe 2 to the left and right by connecting the tee 15, so that the aeration main pipe 2 that is diverted forms a "U"-shaped aeration main pipe;

[0039] S5, select the outlet node of the aeration main pipe 2 according to the designed return groove position of the aeration plate 4 on the "U"-shaped aeration main pipe, open a hole through the water distribution saddle 5 at each outlet node and connect and install the aeration branch pipe 3. After the installation is completed, install an external thread ball valve 6 on each aeration branch pipe 3, and then connect the aeration plate 4 to the other end of the aeration branch pipe 3 and tighten it with a pipe clamp 9;

[0040] S6. Cut the leather wire rope 10 according to the water level of the return ditch of the breeding pond. The length of the wire rope 10 is generally the high water level of the return ditch of the breeding pond all year round to prevent the float from being submerged when the water level is high. Connect one end of the cut wire rope 10 to the aeration plate 4 and the other end to the float 11. The float 11 is exposed on the water surface 14 to serve as a mark, which is convenient for the daily maintenance of the aeration plate 4 in the later stage. At this point, the aeration device is installed.

[0041] After the aeration device is installed, the aeration main unit 1 is turned on, and the air enters each aeration branch pipe 3 through the check valve 8 and the aeration main pipe 2. The outer ball valve 6 is turned on, and the air enters the aeration plate 4 through the aeration branch pipe 3, thereby oxygenating the water in the return ditch. In addition, since the aeration main pipe 2 is a closed "U" shape as a whole, its air outlet is uniform. When the aeration main unit 1 is turned off, the built-in check valve of the aeration plate 4 and then the check valve 8 at the air outlet end of the aeration main unit 1 are automatically closed, so that the water backflow is prevented, which plays a role in double-layer protection of the aeration main unit 1.

[0042] Through the above embodiments, the present invention provides an aeration device for a "U"-shaped aquaculture pond and an installation method thereof, wherein an aeration main unit is arranged on the shore, and an aeration main pipe is closed and arranged along the inner edge of the return ditch of the "U"-shaped aquaculture pond for a circle, thereby solving the problem of no air transmission pipe on the shore for aeration installation, avoiding damage to the aeration main pipe due to later pond maintenance such as return ditch dredging, and also reducing the cost of aeration installation; in addition, the aeration device and the installation method of the present invention have been specifically applied in a certain "U"-shaped aquaculture pond, wherein the dissolved oxygen in the water body is aerated uniformly, the application effect is good, and the aeration device is suitable for wide promotion and use.

[0043] It should be understood that the parts not described in the specification are prior art or common knowledge. This embodiment is only used to illustrate the invention, and is not used to limit the scope of the invention. Modifications such as equivalent substitution made by those skilled in the art to the invention are considered to fall within the scope of protection of the claims of the invention.
