Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and specifically to an automatic oxygenation and aeration device for grass carp fry ponds. Background Technology

[0002] Aquaculture is a production industry that utilizes suitable waters to cultivate aquatic economic plants and animals. In the process of raising grass carp fry, automatic aeration devices are typically used to increase oxygen levels in the pond.

[0003] In typical automatic aeration and oxygenation systems, the aerators are usually exposed in the pond water. When not in use, impurities and debris in the water settle onto the aerators and enter the aeration holes, causing blockages and affecting the aeration efficiency of the automatic aeration and oxygenation system. Therefore, how to effectively prevent aerators from being blocked by impurities in the water when not in use is an important issue that needs to be addressed in the design of automatic aeration and oxygenation systems for grass carp fry ponds. Utility Model Content

[0004] This invention provides an automatic oxygenation and aeration device for grass carp fry ponds to solve the problem of impurities and dirt in the water clogging the aerator holes when the device is not in use.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides an automatic oxygenation and aeration device for grass carp fry ponds, including grass carp fry ponds, and further comprising:

[0007] A piston-driven structure is installed at the bottom of a grass carp fry pond.

[0008] A blocking structure is provided, which is mounted on a piston-driven structure. The piston-driven structure moves to drive the blocking structure to rotate.

[0009] Preferably, an oxygenation pump is fixedly installed on the ground at the top of the grass carp fry pond. The output end of the oxygenation pump is fixedly connected to an oxygenation pipe. The oxygenation pipe is fixedly installed inside the bottom side wall of the grass carp fry pond. Oxygenation branch pipes are fixedly connected at equal intervals on the top side wall of the oxygenation pipe. Aerators are fixedly connected to the top of the oxygenation branch pipes.

[0010] In this technical solution, the oxygenation pump delivers oxygen through the oxygen supply pipe and the oxygen supply branch pipe into the aerator and the ventilation pipe.

[0011] Preferably, a controller and an oxygen sensor are fixedly installed on the ground of the top side wall of the grass carp fry pond, and the detection end of the oxygen sensor extends into the grass carp fry pond.

[0012] In this technical solution, an oxygen sensor detects the oxygen content in the grass carp fry pond.

[0013] Preferably, the oxygen sensor, controller, and oxygen pump are electrically connected in sequence.

[0014] In this technical solution, when the detected oxygen content is low, the controller controls the oxygen pump to deliver oxygen; when the detected oxygen content is high or low, the controller stops the oxygen pump from delivering oxygen.

[0015] Preferably, the piston-driven structure includes a piston housing, a push plate, a connecting plate, a fixing block, a piston block, and an air pipe. The piston housing is fixedly installed on the bottom side wall of the grass carp fry pond. The piston housing is located on both sides of the aerator. The air pipe is fixedly connected between the piston housing and the air pipe. The piston block is slidably connected inside the piston housing. The push plate is fixedly connected to the top of the piston block. The push plate extends upward out of the piston housing. The top of the push plate is rotatably connected to one end of the connecting plate. The other end of the connecting plate is rotatably connected to the fixing block.

[0016] In this technical solution, the vent pipe introduces oxygen into the piston housing, which pushes the piston block to move upward. The piston block then pushes the pusher plate to move upward, and the pusher plate pushes the connecting plate to move upward.

[0017] Preferably, the sealing and blocking structure includes a fixed rod, a blocking plate, a snap-fit ​​groove, and a threaded groove. The fixed rod is fixedly connected to the side walls on both sides of the piston housing. The blocking plate is rotatably connected between the fixed rods. The end of the blocking plate is set with an arc-shaped structure. Snap-fit ​​grooves are provided on the side walls at the top and bottom of the blocking plate. Threaded grooves are provided on the side walls of the snap-fit ​​grooves.

[0018] In this technical solution, the connecting plate pushes the baffle plate to rotate upward, thereby opening the top of the aerator.

[0019] Preferably, a limiting stop is fixedly connected to the side wall of the fixing rod.

[0020] In this technical solution, the limiting rod restricts the rotation angle of the baffle plate to prevent the baffle plate from rotating excessively to both sides.

[0021] Preferably, the blocking structure includes a snap-fit ​​bracket, fixing bolts, and a sealing gasket. The end of the snap-fit ​​bracket is provided with an arc-shaped structure, the sealing gasket is fixedly connected to the bottom side wall of the snap-fit ​​bracket, and the fixing bolt is threadedly connected to the top side wall of the snap-fit ​​bracket.

[0022] In this technical solution, the fixing bolts are loosened and removed, and then the snap-fit ​​bracket is pulled to detach it from the cover plate, which allows for easy replacement.

[0023] Preferably, the clip is clipped into the clip groove on the baffle plate, and the fixing bolt is threaded into the thread groove.

[0024] Preferably, the length of the sealing gasket is greater than the diameter of the aerator, and the width of the sealing gasket is greater than the radius of the aerator.

[0025] In this technical solution, the sealing gasket can effectively seal the top of the aerator.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] 1. Oxygen is supplied through an oxygenation pump and introduced into the aerator and ventilation pipe through the oxygen supply pipe and oxygen supply branch pipe. The ventilation pipe introduces oxygen into the piston housing, which pushes the piston block to move upward. The piston block pushes the push plate to move upward, the push plate pushes the connecting plate to move upward, and the connecting plate pushes the baffle plate to rotate upward, so that the top of the aerator opens, which facilitates better oxygenation and aeration in the grass carp fry pond.

[0029] 2. When aeration is not required, the aeration pump stops running, the baffle is no longer pushed, and the tilted baffle will rotate downwards under the pressure of the water in the grass carp fry pond, covering the top of the aerator again. The sealing gasket seals the top of the aerator, which facilitates better sealing and blocking of the top of the aerator, and prevents the aerator from being blocked by impurities in the water when it is not in use.

[0047] The vent pipe 806 introduces oxygen into the piston housing 801, which pushes the piston block 805 to move upward. The piston block 805 pushes the push plate 802 to move upward, and the push plate 802 pushes the connecting plate 803 to move upward.

[0048] The sealing and blocking structure 9 includes a fixing rod 901, a blocking plate 902, a snap-fit ​​groove 903, and a threaded groove 904.

The sealing gasket 913 seals the top of the aerator 7, which facilitates better sealing and blocking of the top of the aerator 7, and prevents the aerator 7 from being blocked by impurities in the water when it is not in use.
