TECHNICAL FIELD
[0001] The utility model belongs to the fish pond increases equipment field. BACKGROUND
[0002] It is a common fish breeding method to use the oxygenation device to supplement oxygen for the fish pond water body to avoid the fish group from dying due to oxygen deficiency. There are many kinds of oxygenation devices, and the typical ones include the impeller type oxygenation machine, the jet type oxygenation machine, the water spraying type oxygenation machine and the wave type oxygenation machine. The structures of these oxygenation devices are different, but they are all fixed in the fish pond when oxygenating the fish pond, and the oxygenation range is small. The oxygen content of the water body far from the device is obviously lower than that of the water body near the device, which leads to uneven oxygen distribution in the fish pond. This does not have a great impact on the fish in the short term, but it is not good in the long term. The main manifestations are as follows: the fish has oxygenotaxis, and instinctively gathers in the high-oxygen area, which leads to excessively high local density, increases the probability of fighting and damaging the body surface, and causes infection and death.

The two ends of the upper deceleration plate are fixed to two floating blocks respectively, and a height-adjustable lower deceleration plate is screwed to one side of the upper deceleration plate.
[0012] Compared with existing technologies, this invention utilizes a water-spraying mechanism to aerate the fishpond by striking the water surface. The water-spraying mechanism is connected to a floating mechanism, which is connected to a central shaft via a float. After the central shaft is fixed to the bottom of the fishpond, the floating mechanism rotates around the central shaft under the driving force generated by the water-spraying mechanism, greatly expanding the aeration range.

[0015] By setting multiple through holes in the water-spraying plate, the water droplets produced by the plate are made finer, thus improving the oxygenation effect.
[0016] The speed reduction plate slows down the movement speed of the floating mechanism, giving passing fish enough time to escape and preventing them from being injured by the water-spraying plate. In addition, the relative speed between the water-spraying plate and the water surface can be higher when the water-spraying plate rotates, resulting in more and higher splashes, thus improving the oxygenation effect.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0024] Example: A fishpond aeration device, such as Figure 1 As shown, the float includes a floating rod 1 positioned on the surface of the fishpond. The floating rod 1 can be made of PP pipe. One end of the floating rod 1 is fixed with a collar 4, and a central shaft 2 is provided inside the collar 4. The collar 4 and the central shaft 2 are fitted with a clearance fit. The upper end of the central shaft 2 protrudes above the water surface, and the lower end of the central shaft 2 is inserted into the bottom of the fishpond. The other end of the floating rod 1 is connected to a floating mechanism, which is equipped with a water-spraying mechanism and a drive mechanism connected to the water-spraying mechanism.
[0025] The floating mechanism includes two rectangular floating blocks 5, which can be hollow blow-molded plastic parts. One of the floating blocks 5 is fixed to the floating rod 1. Two parallel first rotating shafts 6 are provided between the two floating blocks 5, and the two ends of the first rotating shafts 6 are rotatably connected to the top of the two floating blocks 5 respectively.
[0026] The water-spraying mechanism includes four rollers 7 fixed on a first rotating shaft 6. Each roller 7 has six evenly distributed circumferential water-spraying plates 3 on its outer circumferential surface. A slot 8 is provided on the outer circumferential surface of the roller 7, and an insert 9 is located within the slot 8 on the inner end of each water-spraying plate 3. Multiple through holes 10 are provided on each water-spraying plate 3, which allow the water spray from the water surface to be finer, increasing the oxygenation effect. The rollers 7 and water-spraying plates 3 are tightly fitted together for easy replacement if the water-spraying plates 3 are damaged. Both the rollers 7 and water-spraying plates 3 are made of plastic.
[0027] The drive mechanism includes a mounting bracket 11 located between two first rotating shafts 6. Both ends of the mounting bracket 11 are fixed to two floating blocks 5. A dual-output shaft motor 12 is mounted above the mounting bracket 11 and is fixed to the mounting bracket 11 via corresponding brackets. Each output end of the dual-output shaft motor 12 has a second rotating shaft 13, which is rotatably connected to the top of the corresponding floating block 5. A pulley mechanism 14 is provided between the second rotating shaft 13 and the corresponding first rotating shaft 6. The pulley mechanism 14 includes two synchronous pulleys, which are respectively fixed to the second rotating shaft 13 and the first rotating shaft 6. A synchronous belt is provided between the two synchronous pulleys. When one synchronous pulley rotates, it drives the other synchronous pulley to rotate via the synchronous belt. The pulley mechanism 14 is a common transmission mechanism.
[0028] The outer side of the dual-output shaft motor 12 is provided with an inverted U-shaped baffle plate 15, and both ends of the baffle plate 15 are fixed to the mounting bracket 11.
[0029] The upper end of the central shaft 2 is provided with a waterproof conductive slip ring 16. The dual-output shaft motor 12 is connected to the mains power through the conductive slip ring 16. The conductive slip ring 16 is used to prevent the power cord on the dual-output shaft motor 12 from getting tangled on the central shaft 2.
[0030] The mounting bracket 11 has an upper deceleration plate 17 at its lower end. Both ends of the upper deceleration plate 17 are fixed to two floating blocks 5 respectively. A height-adjustable lower deceleration plate 18 is screwed to one side of the upper deceleration plate 17. The lower deceleration plate 18 has a vertical elongated hole, and a screw for connecting the upper deceleration plate 17 is installed in the elongated hole. After the screw is loosened, the height of the lower deceleration plate 18 can be adjusted. After the adjustment is complete, the screw is tightened.
[0031] Working principle: With the buoyancy support of the two floating blocks 5, the dual-shaft motor 12 is above the water surface, and is kept at a safe distance so that it will not be submerged in the water. Figure 4 The dotted line indicated by B represents the water surface. When the dual-shaft motor 12 is energized, the second shaft 13 rotates. The second shaft 13 drives the first shaft 6 to rotate via the pulley mechanism 14. The first shaft 6 drives the water-spraying plate 3 to rotate via the roller 7. The high-speed rotation of the water-spraying plate 3 strikes the water surface, causing water to splash and increasing the oxygen content of the fishpond. The baffle plate 15 prevents water from splashing onto the dual-shaft motor 12. Preferably, the dual-shaft motor 12 is waterproof to prevent water ingress in strong winds and waves.
[0032] As the two first rotating shafts 6 rotate in the same direction, all the water-beating plates 3 rotate in the same direction. When the water-beating plates 3 hit the water surface, they generate a driving force. Under the action of the floating rod 1, the floating block 5 rotates around the central axis 2, thus expanding the oxygenation range.
[0033] If the floating block 5 moves too fast during its movement, the fish in the pond may not be able to avoid it in time, potentially causing injury. Therefore, the speed of the floating block 5 is reduced by using a speed reducer. The speed of the floating block 5 can be changed by altering the height of the lower speed reducer 18. The speed of the floating block 5 should be kept below 0.5 m / s.
[0034] The water generates a pushing force on the forward deceleration plate, which will cause the rear end of the floating block 5 to tilt upwards to a certain extent. This will result in different water depths for the water-spraying plates on the front and rear rollers. Slight differences are not a problem. If the tilt angle of the floating block 5 is large, a counterweight can be placed on the rear end of the floating block 5 to balance it.
[0035] Since this invention is mainly for surface aeration, it is suitable for use in shallow fish ponds (depth less than 2.5 meters). Sturgeon ponds are generally between 1.5 and 2.5 meters deep, making this invention a suitable option for aeration.
