Description

Technical Field

[0001] This utility model belongs to the field of cultivation and oxygenation technology, specifically an oxygenation device for fish fry cultivation. Background Technology

[0002] Fish fry are affected by egg quality and hatching environment, resulting in variations in fry constitution that directly impacts later survival and growth. Hypoxia in the water is also a major cause of wintering mortality in pond fish. To maintain a relatively stable level of phytoplankton and dissolved oxygen in wintering ponds, it's crucial to increase light penetration, control phytoplankton growth, prevent excessive organic matter, and improve dissolved oxygen levels. Existing aeration systems often only allow the oxygen delivery pipes to remain on the water surface during operation, preventing them from reaching deep into the pond. If excessively long oxygen delivery pipes are used to reach deep into the pond, managing the pipes after operation is extremely cumbersome, thus affecting efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an oxygenation device for fish fry cultivation, which solves the problem that existing oxygenation devices often only allow the oxygenation pipe to remain on the water surface during operation, making it impossible to extend the oxygenation pipe deep into the breeding pond. Furthermore, if the oxygenation pipe is extended deep into the breeding pond using an excessively long oxygenation pipe, the subsequent management of the pipe after operation is very cumbersome, thus affecting work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oxygenation device for fish fry cultivation, comprising an installation block, an oxygen generator fixedly connected to the top of the installation block, an installation groove formed on one side of the installation block, a connecting shaft fixedly connected to one side of the installation groove, a receiving wheel movably connected through the surface of the connecting shaft, an installation shaft fixedly connected to the end of the receiving wheel away from the connecting shaft, a fixed cylinder slidably connected to one end of the installation shaft, a rotating rod fixedly connected to one end of the installation shaft, and the rotating rod rotatably connected to the installation block and the fixed cylinder, a return spring sleeved on the outer arc surface of the rotating rod located inside the fixed cylinder, one end of the fixed cylinder fixedly connected to the inner wall of the installation groove, a rotating handle fixedly connected to one end of the rotating rod through the installation block, a snap-fit ​​toothed ring fixedly connected to one side of the installation groove corresponding to the position of the connecting shaft, a fixed toothed ring fixedly connected to one end of the receiving wheel corresponding to the snap-fit ​​toothed ring, and the fixed toothed ring and the snap-fit ​​toothed ring snap together, and an oxygen supply tube wound around the surface of the receiving wheel.

[0005] As a further embodiment of this utility model: a mounting cylinder is fixedly connected to the bottom of the mounting block, and a threaded rod is rotatably connected inside the mounting cylinder via a bearing.

[0006] As a further embodiment of this utility model: the bottom of the threaded rod is fixedly connected to the mounting cylinder through a connecting handle, and the external thread of the threaded rod is threadedly connected to a rotating block.

[0007] As a further embodiment of this utility model: the outer arc surface of the rotating block is rotatably connected to a connecting arm via a pin, and the number of the connecting arms is three.

[0008] As a further embodiment of this utility model: a sliding groove is provided on the surface of the mounting cylinder corresponding to the position of the connecting arm, and the connecting arm is slidably connected inside the sliding groove. The end of the connecting arm away from the rotating block is rotatably connected to a support rod by a pin.

[0009] As a further embodiment of this utility model: the top of the support rod is rotatably connected to the top of the mounting cylinder by a pin, and the bottom of the support rod is rotatably connected to a rubber seat by a pin.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This aeration equipment for fish fry rearing is equipped with a rotating rod, a mounting shaft, and a storage wheel. When line management is required, pulling the rotating handle moves the rotating rod, mounting shaft, and storage wheel toward one side of the rotating handle. At the same time, the fixing toothed ring on one side of the storage wheel is removed from the snap-fit ​​toothed ring, so that the fixing toothed ring and the snap-fit ​​toothed ring are no longer snapped together. At this time, the rotating handle can be rotated, causing the rotating handle to rotate the storage wheel and the oxygen supply tube, thereby storing or releasing the oxygen supply tube. This makes it convenient to put the oxygen supply tube into the depth of the breeding pond, and also convenient to store the oxygen supply tube.

[0012] 2. This aeration equipment for fish fry cultivation is equipped with a rotating handle, a threaded rod, and a connecting arm. When it is necessary to deploy or store the aeration equipment, the rotating handle can be rotated to drive the threaded rod to rotate. The threaded rod drives the rotating block and the connecting arm to move up and down, so that the connecting arm rotates on the surface of the support rod. The connecting arm can be controlled to lift the support rod, making it easy to control the deployment or storage of the support rod, and thus deploying or storing the device.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an oxygenation device for fish fry cultivation, including an installation block 1, an oxygen generator 2 fixedly connected to the top of the installation block 1, an installation groove 3 opened on one side of the installation block 1, a connecting shaft 4 fixedly connected to one side of the installation groove 3, a storage wheel 5 movably connected through the surface of the connecting shaft 4, and an installation shaft 6 fixedly connected to the end of the storage wheel 5 away from the connecting shaft 4. By setting the storage wheel 5, the storage wheel 5 is driven to rotate, causing the oxygen supply tube 11 to be wound around the surface of the storage wheel 5, thereby winding and storing the oxygen supply tube 11 through the storage wheel 5.

[0019] One end of the mounting shaft 6 is slidably connected to the fixed cylinder 7, and the other end of the mounting shaft 6 is fixedly connected to the rotating rod 9. The rotating rod 9 is rotatably connected to the mounting block 1 and the fixed cylinder 7. The outer arc surface of the rotating rod 9 located in the fixed cylinder 7 is sleeved with a return spring 8. By setting the return spring 8, when the rotation handle 10 and the rotating rod 9 are stopped, the elastic force of the return spring 8 drives the storage wheel 5 to reset, so that the storage wheel 5 can return to its original position.

[0020] One end of the fixed cylinder 7 is fixedly connected to the inner wall of the mounting groove 3. One end of the rotating rod 9 passes through the mounting block 1 and is fixedly connected to the rotating handle 10. A snap-fit ​​toothed ring 13 is fixedly connected to one side of the mounting groove 3 corresponding to the position of the connecting shaft 4. A fixed toothed ring 12 is fixedly connected to one end of the receiving wheel 5 corresponding to the snap-fit ​​toothed ring 13, and the fixed toothed ring 12 and the snap-fit ​​toothed ring 13 snap together. An oxygen supply tube 11 is wound around the surface of the receiving wheel 5. Through the setting of the snap-fit ​​toothed ring 13 and the fixed toothed ring 12, when the receiving wheel 5 is reset, the receiving wheel 5 can drive the fixed toothed ring 12 to snap into the snap-fit ​​toothed ring 13. The snap-fit ​​toothed ring 13 is used to snap the fixed toothed ring 12 to lock and fix the receiving wheel 5.

[0021] The bottom of the mounting block 1 is fixedly connected to the mounting cylinder 14. The mounting cylinder 14 is rotatably connected to the threaded rod 15 through the bearing. The bottom of the threaded rod 15 passes through the mounting cylinder 14 and is fixedly connected to the connecting handle 16. The external thread of the threaded rod 15 is threadedly connected to the rotating block 18. By setting the threaded rod 15, the connecting handle 16 drives the threaded rod 15 to rotate, thereby controlling the rotating block 18 to move.

[0022] A sliding groove 17 is provided on the surface of the mounting cylinder 14 at the position corresponding to the connecting arm 19, and the connecting arm 19 is slidably connected inside the sliding groove 17. The end of the connecting arm 19 away from the rotating block 18 is rotatably connected to the support rod 20 through a pin. With the support rod 20 set, the connecting arm 19 drives the support rod 20 to unfold or retract, so that the support rod 20 can be unfolded to support the whole.

[0023] The top of the support rod 20 is rotatably connected to the top of the mounting cylinder 14 via a pin, and the bottom of the support rod 20 is rotatably connected to a rubber seat 21 via a pin. With the setting of the rubber seat 21, the rubber seat 21 rotates adaptively by contacting the ground and rotating through the pin connection, so that the rubber seat 21 can be placed horizontally on the ground.

[0024] The working principle of this utility model is as follows: First, by rotating the connecting handle 16, the threaded rod 15 is rotated. When the threaded rod 15 rotates, it drives the rotating block 18 and the connecting arm 19 to slide downward in the sliding groove 17. At this time, the connecting arm 19 supports the support rod 20, thereby unfolding the support rod 20. The three support rods 20 are deployed by contacting the rubber seat 21 with the plane. Then, the rotating handle 10 can be pulled in the opposite direction to the storage wheel 5. The rotating rod 9, mounting shaft 6, and receiving wheel 5 move the fixed gear ring 12, causing the fixed gear ring 12 to disengage from the locking gear ring 13. At this time, the rotating handle 10 can be rotated, which in turn rotates the rotating rod 9, mounting shaft 6, and receiving wheel 5, causing the receiving wheel 5 to rotate the oxygen supply pipe 11, thus discharging the oxygen supply pipe 11 and extending it to the appropriate length. Then, the oxygen generator 2 can be started, and oxygen can be transported into the aquaculture pond through the oxygen supply pipe 11.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
