Description
Technical Field
[0001] This utility model belongs to the field of aquaculture technology, and more specifically, it relates to solar-powered aquaculture oxygenation equipment. Background Technology
[0002] In aquaculture, when the stocking density in a pond is high, oxygen deficiency can easily occur, necessitating artificial aeration. Among various aeration methods, solar-powered aquaculture aeration equipment is widely used due to its energy-saving and environmentally friendly advantages. Existing solar-powered aquaculture aeration equipment mainly includes impeller type, waterwheel type, and microporous aeration type, among others. Waterwheel type aeration equipment is widely used due to its high aeration efficiency and its ability to promote water circulation. It uses the rotation of the waterwheel to drive water flow, creating continuous waves on the water surface, thereby significantly increasing the contact area between water and air, and thus efficiently completing the process of oxygenation into the water.
[0003] Existing application number CN202223271679.7 discloses a solar-powered aerator for aquaculture. It features a floating box under a fixed frame, and a solar power supply device and aeration mechanism mounted on the fixed frame. The solar panel assembly automatically adjusts its position and tilt angle according to changes in sunlight, ensuring maximum solar energy generation for the aeration operation. The application also discloses a specific mechanism for adjusting the position, steering, and tilt angle. Through a photosensitive sensor, a steering motor, and an electric telescopic rod, the position of the solar panel assembly under sunlight can be adjusted in real time to ensure optimal sunlight reception, allowing the solar power system to obtain more energy and improving energy storage efficiency. The aeration mechanism includes a dual-head drive motor, with aeration worm gears fixedly connected to the power output shafts at both ends. The worm gears are equipped with weed cutters to prevent aquatic plants from entangled in the aeration turbine, enabling continuous, fixed-point aeration while preventing the impact of weed entanglement on the aeration operation.
[0004] Based on the above, existing solar-powered aeration equipment for aquaculture, when using waterwheels for aeration, can easily injure fish gathered around the equipment when the waterwheel suddenly starts and begins to rotate and stir the water. At best, the fish will be injured by the blades, causing damage to their bodies; at worst, they may be directly pulled into the waterwheel structure and die. The dead fish will decompose and pollute the aquatic environment of the aquaculture pond, thus affecting the survival of other aquatic organisms. Even injured fish will have their appearance affected, directly reducing their market value. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a solar-powered aeration equipment for aquaculture. This addresses the issue of existing solar-powered aeration equipment using waterwheels. When the waterwheel suddenly starts and begins rotating to agitate the water, fish gathered around the equipment are easily injured by the sudden rotation.

The ends of the two pairs of second connecting rods are hinged to the tops of the two sets of transmission shafts.
[0010] Furthermore, the drive assembly also includes: a reset spring, a first locking block, and a second locking block. The reset spring is provided in two sets, with one end of each set fixedly connected to the top of the two output shafts and the other end fixedly connected to the top of the two transmission shafts. The first locking block is provided in two sets, with each set fixedly installed in the middle of the two transmission shafts. The second locking block is provided in two sets, with each set fixedly installed at the end of the two transmission shafts.
[0011] Furthermore, the drive assembly also includes: a first rotating shaft, a first slot, a second rotating shaft, and a second slot. Two sets of the first rotating shaft are provided, each rotatably connected to the inner side of the upper part of one of the two support frames. Two sets of the first slot are provided, each located at the right end of one of the two sets of the first rotating shaft. Two sets of the second rotating shaft are provided, each rotatably connected to the outer side of the upper part of one of the two support frames, and each coaxially fixedly installed inside one of the two oxygenation water carts. Two sets of the second slot are provided, each located at the left end of one of the two sets of the second rotating shaft.
[0012] Furthermore, the tapping assembly includes: a cam and a synchronization mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] Firstly, this invention features a drive assembly that achieves timing control through the combination of centrifugal force and mechanical transmission. After the motor starts, the centrifugal force generated by the rotation of the centrifugal ball drives the transmission shaft to slide via a connecting rod, causing the first and second locking blocks to alternately engage with their corresponding slots. This first drives the first rotating shaft to rotate, and then the aeration waterwheel is started after a delay, preventing sudden start-up of the waterwheel from causing damage to the fish. It eliminates the need for complex electronic control components, achieving timing switching solely through a mechanical structure, thus improving equipment stability.
[0016] Secondly, this invention features a striking component that creates a continuous frightening effect through the linkage of a cam and an elastic element. When the first rotating shaft rotates, the cam is driven to rotate via a synchronization mechanism. The cam periodically pushes the striking plate to swing, and with the reset action of the elastic torsion spring, the striking plate continuously strikes the water surface, generating splashes and vibrations. This effectively frightens surrounding fish, prompting them to stay away from the equipment area and reducing the possibility of fish coming into contact with the waterwheel from the source.
[0017] This invention has advantages such as time-sequence switching, fish dispersal, and ease of use. Through mechanical structure, it achieves a continuous operation of first frightening and then oxygenating, which not only ensures oxygenation efficiency but also reduces the risk of fish injury and effectively reduces the damage to fish caused by sudden waterwheel start-up.

[0028] This utility model provides a solar-powered aeration equipment for aquaculture, including a hollow float 1, a solar panel 2, a drive motor 3, a support frame 4, an aeration waterwheel 5, and a drive assembly.

[0029] The drive assembly includes an output shaft 301, a guide shaft 302, and a transmission shaft 303. Two sets of output shafts 301 are provided, and the two sets of output shafts 301 are installed on the left and right sides of the hollow float 1. Two sets of guide shafts 302 are provided, and the two sets of guide shafts 302 are coaxially fixedly installed on the top of the two sets of output shafts 301. Two sets of transmission shafts 303 are provided, and the two sets of transmission shafts 303 are slidably connected to the outside of the two sets of guide shafts 302.
[0030] The drive assembly also includes: a first connecting rod 3011, a centrifugal ball 3012, and a second connecting rod 3013. The first connecting rod 3011 is provided in two pairs, and the ends of the two pairs of first connecting rods 3011 are hinged to the tops of the two sets of output shafts 301. The centrifugal ball 3012 is provided in two pairs, and the two pairs of centrifugal balls 3012 are respectively fixedly installed on the tops of the two pairs of first connecting rods 3011. The second connecting rod 3013 is provided in two pairs, and the tops of the two pairs of second connecting rods 3013 are hinged to the tops of the two pairs of first connecting rods 3011. The ends of the two pairs of second connecting rods 3013 are hinged to the tops of the two sets of transmission shafts 303.
[0031] The drive assembly also includes: a reset spring 3021, a first locking block 3031, and a second locking block 3032. Two sets of reset springs 3021 are provided, with one end of each set fixedly connected to the top of the two sets of output shafts 301 and the other end fixedly connected to the top of the two sets of transmission shafts 303. Two sets of first locking blocks 3031 are provided, with the two sets of first locking blocks 3031 fixedly installed in the middle of the two sets of transmission shafts 303. Two sets of second locking blocks 3032 are provided, with the two sets of second locking blocks 3032 fixedly installed at the ends of the two sets of transmission shafts 303.
[0032] The drive assembly also includes: a first rotating shaft 401, a first slot 4011, a second rotating shaft 402, and a second slot 4021. Two sets of the first rotating shaft 401 are provided, each rotatably connected to the inner upper part of one of the two support frames 4. Two sets of the first slot 4011 are provided, each located at the right end of one of the two first rotating shafts 401. Two sets of the second rotating shaft 402 are provided, each rotatably connected to the outer upper part of one of the two support frames 4, and coaxially fixedly installed inside one of the two oxygenation water carts 5. Two sets of the second slot 4021 are provided, each located at the left end of one of the two second rotating shafts 402.
[0033] The specific usage and function of this embodiment are as follows:
[0034] Under normal conditions, the return spring 3021 is in a naturally extended state, driving the drive shaft 303 to slide along the outside of the guide shaft 302 to the initial position. In this state, the first locking block 3031 on the drive shaft 303 is precisely engaged in the first locking groove 4011 of the first rotating shaft 401, while the second locking block 3032 remains separated from the second locking groove 4021 of the second rotating shaft 402.
[0035] When the solar panel 2 generates electricity through sunlight and stores and converts it, the drive motor 3 is powered on and starts, causing the output shaft 301 to start rotating. The rotation of the output shaft 301 synchronously drives the guide shaft 302 and the transmission shaft 303 to rotate. At this time, due to the engagement of the first locking block 3031 and the first locking slot 4011, the first rotating shaft 401 rotates synchronously with the transmission shaft 303, while the second rotating shaft 402 remains stationary because the second locking block 3032 is not engaged in the second locking slot 4021, so that the oxygenation water cart 5 does not start temporarily.
[0036] As the output shaft 301 gradually increases in speed, it drives the centrifugal ball 3012 to rotate via the first connecting rod 3011, generating centrifugal force. When the centrifugal force reaches a preset value, under the transmission action of the second connecting rod 3013, the transmission shaft 303 overcomes the elastic force of the return spring 3021 and slides along the guide shaft 302 toward the output shaft 301. During this process, the first locking block 3031 disengages from the first locking slot 4011, and the first rotating shaft 401 stops rotating; simultaneously, the second locking block 3032 engages with the second locking slot 4021, driving the second rotating shaft 402 to rotate the aeration water truck 5, thus initiating the aeration operation.
[0037] Through the above-mentioned structural linkage, after the drive motor 3 starts, the first rotating shaft 401 rotates for a period of time, and then the second rotating shaft 402 rotates to start the oxygenation water cart 5 for oxygenation. Example
[0038] Based on Example 1, such as Figures 1 to 6As shown, it also includes: a flapping component, which is disposed on the left and right sides of the hollow float 1.
[0039] The striking assembly includes a cam 404 and a synchronization mechanism 403. Two sets of cams 404 are provided, and the two sets of cams 404 are rotatably connected to the lower part of the two sets of support frames 4 respectively. Two sets of synchronization mechanisms 403 are provided, and the two sets of synchronization mechanisms 403 are respectively installed on the outside of the two sets of first rotating shafts 401, and the two sets of synchronization mechanisms 403 are respectively installed on one side of the two sets of cams 404.
[0040] The slapping assembly also includes: a support shaft 405, a slapping plate 4051, and an elastic torsion spring 4052. Two sets of support shafts 405 are provided, and the two sets of support shafts 405 are fixedly connected to the lower part of the two sets of support frames 4 respectively. Two sets of slapping plates 4051 are provided, and the two sets of slapping plates 4051 are rotatably connected to the outside of the two sets of support shafts 405 respectively. Two sets of elastic torsion springs 4052 are provided, and the two sets of elastic torsion springs 4052 are installed in the middle position between the support shaft 405 and the slapping plate 4051.
[0041] The specific usage and function of this embodiment are as follows:
[0042] When the first rotating shaft 401 rotates under the drive of the drive assembly, it transmits power to the cam 404 through the synchronization mechanism 403, causing the cam 404 to rotate synchronously with the first rotating shaft 401. During the rotation of the cam 404, its protrusion will periodically contact the striking plate 4051 and push the striking plate 4051 to swing around the support shaft 405. At this time, the elastic torsion spring 4052 installed between the support shaft 405 and the striking plate 4051 will deform due to the force and store elastic potential energy.
[0043] When the protrusion of the cam 404 disengages from the beater plate 4051, the elastic torsion spring 4052 releases its elastic potential energy, causing the beater plate 4051 to quickly reset and swing downwards, creating a powerful impact on the water surface. Through the continuous rotation of the cam 404 and the reciprocating reset action of the elastic torsion spring 4052, the beater plate 4051 continuously strikes the water surface, producing regular splashes and vibrations. This startles nearby fish before the aerator waterwheel 5 starts, causing them to move away from the equipment area and further preventing contact damage between the fish and the subsequently activated aerator waterwheel 5.
