[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] There is a risk that the upper rotifers may be discharged during the drainage process in the above-mentioned device. When the operator opens the drain valve to discharge the old water on the bottom layer, if the operation is too fast, the upper water may be sucked into the drain pipe and discharged together.

[0030] Embodiment 1:

[0031] like Figures 1 to 4 The utility model provides a circulating outdoor earth pond rotifer cultivation device.

[0032] Specifically, by Figure 1-4 A circulating outdoor earth pond rotifer cultivation device is provided, comprising a cultivation pool 1, wherein a barrier assembly 2 is arranged inside the cultivation pool 1, wherein the barrier assembly 2 comprises a servo motor 201, wherein the servo motor 201 is arranged inside the cultivation pool 1, wherein a gear 202 is connected to a driving end of the servo motor 201, wherein the gear 202 is meshingly connected to a rack 203, wherein a connecting rod 204 is fixedly connected to one side of the gear 202, wherein a numbering net 205 is wound around an outer wall of the connecting rod 204.

[0033] The lighting device 8 is turned on. Since rotifers have phototaxis, the rotifers are attracted to the upper water level, so that the rotifers are separated from the underwater impurities by a distance. Then the servo motor 201 is started by controlling the single chip microcomputer. The driving end of the servo motor 201 drives the gear 202 to rotate, so that the gear 202 moves linearly on the rack 203. The gear 202 drives the connecting rod 204 to rotate, so that the number net 205 on the connecting rod 204 is unwound and stretched. The side of the number net 205 away from the connecting rod 204 is installed on the inner wall of the culture tank 1, so that the number net 205 can be better set in the middle of the water after being stretched, and the rotifers can be better separated from the impurities on the bottom of the water.

[0034] By opening the water valve and the water pump 16, the wastewater at the bottom of the culture tank 1 can be discharged from the drain pipe 13 into the filter tank 12 together with the impurities. At this time, the number net 205 plays a blocking role to prevent the drainage operation from being too fast, which may cause the upper water body and rotifers to be sucked into the drain pipe 13 and discharged together. The barrier component 2 can make the drainage more accurate.

[0035] Further:

[0036] like Figure 1 and Figure 3 It is shown that both ends of the rack 203 are fixedly mounted on the inner wall of the culture tank 1, and a slide groove adapted to the connecting rod 204 is opened on the inner wall of the culture tank 1, and one end of the connecting rod 204 away from the gear 202 is slidably connected inside the slide groove.

[0037] The rack 203 needs to maintain a stable position to ensure correct meshing with the gear 202. By fixing its two ends on the inner wall, the rack 203 can be prevented from positional displacement during operation. The existence of the slide groove provides a definite motion trajectory for the connecting rod 204, which ensures that the connecting rod 204 and the components connected thereto can move along a predetermined path, thereby achieving precise control and guidance.

[0038] Further:

[0039] like Figure 3 It is shown that a slider 3 is fixedly installed at the bottom of the servo motor 201, a ball 4 is arranged inside the slider 3, a slide rail 5 is fixedly installed on the inner wall of the culture pool 1, the ball 4 is rollingly connected to the slide rail 5, and a lighting device 8 is arranged above the culture pool 1.

[0040] Balls 4 are arranged inside the slider 3, and these balls roll on the slide rail 5. Since the friction coefficient between the ball 4 and the slide rail 5 is small, this design enables the servo motor 201 to move along the slide rail 5 smoothly and accurately.

[0041] Further:

[0042] like Figure 3-4 It is shown that two limit rods 6 are fixedly installed on the inner wall of the culture pool 1, the slider 3 is slidably connected to the outer wall of the limit rod 6, and a waterproof frame 7 is arranged outside the servo motor 201, and the waterproof frame 7 is fixedly installed on the top of the slider 3.

[0043] The existence of the limit rod 6 provides a stable sliding track for the slider 3. When the slider 3 moves along the limit rod 6, due to the guiding effect of the limit rod 6, it can ensure that the slider 3 and the servo motor 201 remain stable during the movement without shaking or deviating from the predetermined path.

[0044] The waterproof frame 7 can effectively prevent moisture from entering the servo motor 201 and protect the motor from damage in a humid or aquatic environment. The waterproof frame 7 usually has a waterproof sealing function, which can improve the waterproof level of the servo motor 201 and ensure its stability and reliability in a water environment.

[0045] Further:

[0046] like Figure 1-2 It is shown that a filter tank 12 is fixedly installed on one side of the culture tank 1, a plurality of drain pipes 13 are fixedly installed on the inner wall of the filter tank 12, a sluice is provided on the drain pipe 13, a filter barrel 14 is provided below the drain pipe 13, a filter 15 is fixedly installed on the inner wall of the filter tank 12, a water pump 16 is fixedly installed on the outer wall of the filter tank 12, a water inlet pipe 17 is fixedly installed on one side of the water pump 16, and the other end of the water inlet pipe 17 extends to the interior of the culture tank 1.

[0047] The sluice gate provided on the drain pipe 13 can control the switch, speed and flow of the water flow, so that the operator can adjust the speed of the water flow as needed to adapt to different cultivation requirements. The filter barrel 14 can collect the impurities and particulate matter after filtering, which is convenient for regular cleaning and maintenance.

[0048] Energy efficiency optimization of the water pump 16 and the filter 15 also helps to reduce energy consumption. The setting of the water pump 16 enables water to be pumped out of the culture tank 1, filtered by the filter 15, and then flow back to the culture tank 1 through the drain pipe 13 and the water inlet pipe 17. This forms an effective water circulation system, which not only provides a continuous water source for the rotifers, but also helps to maintain the stability of the internal environment of the culture tank 1.

[0049] Embodiment 2:

[0050] Further:

[0051] like Figure 3-4 It is shown that a connecting rod 9 is fixedly connected to one side of the sliding block 3, a plurality of fixing bolts 10 are threadedly connected to the top of the connecting rod 9, a scraper 11 is fixedly installed to the bottom of the connecting rod 9, and the other end of the connecting rod 9 is slidably connected to the inner wall of the culture tank 1.

[0052] The servo motor 201 drives the gear 202 to rotate, so that when it moves on the rack 203, it drives the servo motor 201 and the slider 3 to move toward the drain pipe 13. The drain pipe 13 drives the scraper 11 to move synchronously, and the underwater impurities are deposited near the drain pipe 13, which helps to drain the internal dirt of the culture tank 1. The fixing bolt 10 is used to fix the scraper 11 on the scraper 11 more firmly.

[0053] Working principle: turn on the lighting device 8, because rotifers have phototaxis, they are attracted to the upper water level, so that the rotifers are separated from the underwater impurities by a distance, and then the servo motor 201 is controlled by the single-chip microcomputer to start, and the driving end of the servo motor 201 drives the gear 202 to rotate, so that the gear 202 moves linearly on the rack 203, and the gear 202 drives the connecting rod 204 to rotate, so that the number net 205 on the connecting rod 204 is unwound and stretched, and the side of the number net 205 away from the connecting rod 204 is installed on the inner wall of the culture tank 1, so that the number net 205 can be better set in the middle of the water after being stretched, and the rotifers can be better separated from the impurities on the bottom of the water.

[0054] By opening the water valve and the water pump 16, the wastewater at the bottom of the culture tank 1 can be discharged from the drain pipe 13 into the filter tank 12 together with the impurities. At this time, the number net 205 plays a blocking role to prevent the drainage operation from being too fast, which may cause the upper water body and rotifers to be sucked into the drain pipe 13 and discharged together. The barrier component 2 can make the drainage more accurate.

[0055] The servo motor 201 drives the gear 202 to rotate, so that when it moves on the rack 203, it drives the servo motor 201 and the slider 3 to move toward the drain pipe 13. The drain pipe 13 drives the scraper 11 to move synchronously, and the underwater impurities are deposited near the drain pipe 13, which helps to drain the internal dirt of the culture tank 1. The fixing bolt 10 is used to fix the scraper 11 on the scraper 11 more firmly.

[0056] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention.
