Description

Technical Field

[0001] The utility model relates to the field of crayfish farming, in particular to an oxygen supply device for crayfish farming in paddy fields. Background Technique

[0002] The oxygen supply device for crayfish farming increases the dissolved oxygen content in the water body to provide a suitable living environment for crayfish. This device usually uses mechanical or chemical methods to efficiently transport air or pure oxygen into the breeding frame to ensure sufficient oxygen in the water to meet the breathing and growth needs of crayfish.

[0003] Chinese Patent No. CN218999278U discloses an oxygen supply device for aquaculture, including an air outlet assembly, which is composed of an air outlet pipe, a shunt pipe and a shunt head. One end of the air outlet pipe is movably connected to one end of the shunt pipe, and one side surface of the shunt head is fixedly connected to one side surface of the shunt pipe. Through the shunt pipe, oxygen can be supplied to different water areas to avoid the situation that the dissolved oxygen content in the water in some areas is small and the oxygen content cannot reach the normal level, affecting the survival of aquatic animals in the water.

[0004] When the above-mentioned oxygen supply device for aquaculture supplies oxygen and shunts the oxygen transmission direction, the amount of shunted oxygen is evenly distributed, and the amount of oxygen discharged from each shunt pipe is the same. It cannot actively adjust the amount of oxygen in each shunt direction according to different transmission requirements, making the oxygen supply equipment not flexible to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide an oxygen supply device for crayfish farming in paddy fields. By rotating the threaded rod, the blocking piece can be pushed, and by pushing the blocking piece, the area of the flow cavity can be adjusted, directly adjusting the oxygen transmission amount of the corresponding second connecting pipe, improving the flexible use of the equipment, and solving the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An oxygen supply device for crayfish farming in paddy fields, including an oxygen transmission component composed of a first connecting pipe, a shunt block, a second connecting pipe and a third connecting pipe. A flow rate adjustment frame is arranged outside the second connecting pipe. A blocking piece connected by a sliding card slot is arranged inside the flow rate adjustment frame. The blocking piece realizes the adjustment of the longitudinal horizontal position through the threaded fit between the threaded rod and the flow rate adjustment frame. One end of the shunt block is hermetically provided with an exhaust block. The rotation of the threaded rod can actively push and adjust the longitudinal horizontal position of the blocking piece in the flow rate adjustment frame, and adjust the position of the flow rate adjustment frame to realize the transmission of different amounts of oxygen.

[0007] Preferably, a flow cavity is arranged at the lower end of the outside of the blocking piece. The adjustment of the horizontal position of the blocking piece can correspondingly adjust the area of the flow cavity, and the area of the flow cavity should correspond to different oxygen transmission amounts.

[0008] Preferably, the connection position between the second connection pipe and the flow adjustment frame overlaps with the center position of the flow chamber, and the transmission of the blocking piece can block and restrict the gas transmission of the third connection pipe.

[0009] Preferably, an exhaust hole is provided on one side of the outside of the exhaust block, a movable block is arranged inside the exhaust block near the exhaust hole, and a limiting ring integrally structured with the exhaust block is arranged at the lower end of the movable block. After being adjusted by the blocking piece, there will be a part of the redundant and inescapable gas, and the gas will be discharged from the exhaust hole.

[0010] Preferably, the upper end of the movable block is continuously attached to the limiting ring by the extrusion of the spring. The redundant gas will extrude the movable block, and during daily use, the spring will continuously push the movable block. However, after the gas is discharged, the resilience of the movable block will cause the movable block to reset.

[0011] Preferably, a check valve is arranged between the flow dividing block and the second connection pipe, and the first connection pipe, the flow dividing block, the check valve, the second connection pipe and the third connection pipe are hermetically connected end to end in sequence. The check valve can directly prevent the water in the aquaculture position from flowing back and avoid the damage of the oxygen supply device connected to one end of the first connection pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the oxygen is transmitted by the oxygen transmission component at the oxygen blowing position of the oxygen supply device. When the oxygen is evenly divided by connecting the flow dividing block and the second connection pipe in the oxygen transmission component, the oxygen will pass through the flow chamber and finally be transmitted to the crayfish aquaculture position. After the rotation of the threaded rod generates relative movement with the upper end inside the flow adjustment frame, the blocking piece slides longitudinally and horizontally in the flow adjustment frame, and the remaining area of the position of the flow chamber is directly adjusted by adjusting the blocking piece. By adjusting the remaining area, the oxygen transmission amount inside the corresponding third connection pipe is directly adjusted, and the oxygen amount received at the corresponding transmission position of the third connection pipe is actively adjusted. After the blocking piece adjusts the longitudinal position, a part of the oxygen cannot be discharged smoothly. The redundant oxygen will push the spring inside the exhaust block and then be discharged from the exhaust hole position, actively adapting to the redundant oxygen generated by the adjustment of the blocking piece, avoiding the continuous accumulation of oxygen causing the disconnection of the oxygen transmission component, avoiding the impact of oxygen causing the blocking piece to bear a large pressure, and avoiding the damage of the blocking piece.

Specific embodiments

[0020] The present invention will be further described below in conjunction with specific embodiments.

[0021] As Figure 2 shown, an oxygen supply device for cultivating crayfish in paddy fields in this embodiment includes an oxygen transmission component and a flow adjustment frame 7 for restricting the oxygen flow rate;

[0022] Among them, a blocking piece 10 is arranged in the middle inside the flow adjustment frame 7. A threaded rod 8 is arranged at the upper end of the blocking piece 10, and one end of the threaded rod 8 is rotatably connected to the upper end of the blocking piece 10. The threaded rod 8 penetrates and extends to the upper end of the flow adjustment frame 7, and the upper end inside the flow adjustment frame 7 is in threaded cooperation with the outside of the threaded rod 8. After the threaded rod 8 rotates inside the upper end of the flow adjustment frame 7, it will adjust the longitudinal horizontal position, and the connection between the blocking piece 10 and the threaded rod 8 causes the blocking piece 10 to be driven to adjust its longitudinal position after the threaded rod 8 rotates;

[0023] Specifically, a flow cavity 9 for oxygen flow is arranged between the lower end inside the flow adjustment frame 7 and the lower end outside the blocking piece 10. As Figure 5 shown, the adjustment of the longitudinal horizontal position of the blocking piece 10 can directly adjust the area of the flow cavity 9;

[0024] Specifically in this embodiment, the outside of the blocking piece 10 is connected to the internal sliding card slot of the flow adjustment frame 7. By adjusting the longitudinal position of the blocking piece 10, the area of the flow cavity 9 can be enlarged or reduced. Since the blocking piece 10 is connected to the sliding card slot of the flow adjustment frame 7, after the position of the blocking piece 10 is adjusted, a sealed adjustment of the area of the flow cavity 9 can be realized, avoiding the normal transmission of oxygen from the gap after the oxygen is blocked at the position of the blocking piece 10;

[0025] Refer to Figure 1 and Figure 2, the oxygen transmission component includes a first connecting pipe 1, a shunt block 2, a second connecting pipe 4 and a third connecting pipe 5. Both ends of the first connecting pipe 1 are used to assist in connecting the shunt block 2 and the oxygen supply device, and the oxygen blowing position of the oxygen supply device can be transported to the shunt block 2 after being connected through the first connecting pipe 1;

[0026] Among them, on the other side of the shunt block 2 connected to the first connecting pipe 1, three second connecting pipes 4 are evenly distributed horizontally. On the other side of the three second connecting pipes 4, there is a third connecting pipe 5 for extension. The oxygen inside the first connecting pipe 1 is shunted at the position of the second connecting pipe 4 after being connected by the shunt block 2, and is shunted and transmitted from the third connecting pipe 5 to the oxygen supply position for crayfish farming;

[0027] Specifically, referring to Figure 3 As shown, the flow adjustment frame 7 and the second connecting pipe 4 are of an integral structure, and the connection position of the second connecting pipe 4 and the flow adjustment frame 7 overlaps with the center position of the flow chamber 9.

[0028] Since the rotation of the threaded rod 8 will adjust the area of the flow chamber 9, adjusting the area of the flow chamber 9 correspondingly adjusts the amount of oxygen that can flow. When the area of the flow chamber 9 is reduced, it will directly cause a part of the oxygen to be unable to be discharged. Therefore, in order to avoid the oxygen from being unable to be discharged, an exhaust block 6 is hermetically arranged at one end of the shunt block 2, and the excess oxygen can only flow towards the exhaust block 6;

[0029] Referring to Figure 4 As shown, a limiting ring 11 is arranged around the inside of the exhaust block 6. An active block 12 is arranged at the upper end of the limiting ring 11. A spring 13 for pushing the active block 12 is arranged between the active block 12 and the inner wall of the exhaust block 6. The resilience of the spring 13 will continuously fit the limiting ring 11, and the resilience of the spring 13 enables the active block 12 to adjust its position longitudinally upward only after being subjected to gas pressure;

[0030] Specifically in this embodiment, an exhaust hole 14 is arranged on one side of the outside of the active block 12. When the active block 12 is pushed, the exhaust hole 14 will be exposed, and the gas will be discharged from the exhaust hole 14 after squeezing the active block 12, discharging the excess gas to avoid the continuous accumulation of excess gas in the shunt block 2.

[0031] In order to prevent the gas transmitted by the oxygen from flowing back into the oxygen supply device, a check valve 3 is arranged between the shunt block 2 and the second connecting pipe 4, and the check valve 3 can directly prevent the liquid from flowing back;

[0032] Specifically in this embodiment, in order to achieve the smooth flow of oxygen and the supply of crayfish, the first connecting pipe 1, the shunt block 2, the check valve 3, the second connecting pipe 4 and the third connecting pipe 5 are hermetically connected end to end in sequence.

[0033] Working principle: When using the device to supply oxygen to crayfish at different positions, the oxygen blowing position of the oxygen supply device is connected by the first connecting pipe 1 to receive oxygen. The oxygen is transmitted from the first connecting pipe 1 to the inside of the shunt block 2. The oxygen inside the shunt block 2 is shunted through the second connecting pipe 4. The oxygen is transmitted from the shunt block 2 to the second connecting pipe 4 and flows through the flow cavity 9 inside the second connecting pipe 4 to the third connecting pipe 5, and is discharged from the bubble stone connected to one end of the third connecting pipe 5. Rotate the threaded rod 8. The rotation of the threaded rod 8 can generate relative movement inside the flow rate adjustment frame 7. After being restricted by the flow rate adjustment frame 7, the blocking piece 10 can change from rotational movement to longitudinal linear movement. The longitudinal linear movement of the blocking piece 10 can adjust the area of the flow cavity 9 area. The excess oxygen generated by adjusting the flow cavity 9 will push the movable block 12 and the spring 13. The spring 13 contracts when it is subjected to force. After the movable block 12 contracts, the exhaust hole 14 is exposed. The compressed gas will be discharged from the exhaust hole 14. After the gas is discharged, the resilience of the spring 13 will reset the movable block 12.
