Description

Technical Field

[0001] This utility model relates to the field of fish fry hatching technology, and in particular to a circulating water purification device for fish fry hatching. Background Technology

[0002] During fish fry hatching, circulating water ensures successful hatching. However, the water quality deteriorates over time, containing more impurities that affect the survival rate of the fish fry, necessitating purification.

[0003] In the existing technology, when the purified circulating water is recirculated into the device, it is not convenient to control its flow speed and direction. A single flow speed is difficult to meet the different requirements of slow flow during the egg stage and stable flow during the larval stage. In addition, the impact of the water flow can easily lead to a high rate of egg breakage and a low survival rate of larvae, which affects the hatching rate of fish fry. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when the purified circulating water is recirculated into the device, it is not easy to control the water flow speed and direction, which affects the hatching rate of fish fry. Therefore, this invention proposes a circulating water purification device for fish fry hatching.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circulating water purification device for fish fry hatching, comprising an outer casing, a circulating purification mechanism installed on one side of the outer casing, an hatching mechanism installed inside the outer casing, a flow guiding mechanism provided above the hatching mechanism, the flow guiding mechanism comprising a flow guiding plate, and rotating rods fixedly connected to both ends of the flow guiding plate, one end of one rotating rod being rotatably connected to the inner side of the outer casing, and one end of the other rotating rod passing through the other side of the outer casing and fixedly connected to a first adjusting rod, the other end of the first adjusting rod being rotatably connected to a second adjusting rod, the other end of the second adjusting rod being rotatably connected to a rotating disk, a second connecting rod being fixedly connected to one side of the rotating disk, and the other end of the second connecting rod being rotatably connected to the outer side of the outer casing.

[0006] Preferably, a first connecting rod is fixedly connected to the other side of the rotating disk, a drive motor is fixedly connected to the outside of the outer casing, and a belt assembly is installed between the output end of the drive motor and the first connecting rod.

[0007] Preferably, the incubation mechanism includes two fixing plates, which are respectively fixedly connected to the inner sides of the outer box, and a positioning plate is inserted into the middle of the two fixing plates.

[0008] Preferably, an incubator is fixedly connected to the center of the positioning plate, and an opening is provided on the side wall of the incubator.

[0009] Preferably, the circulating purification mechanism includes a purification box, and a first filter plate, a second filter plate and a third filter plate are fixedly connected inside the purification box. The first filter plate, the second filter plate and the third filter plate are arranged obliquely inside the purification box in sequence, and a communication port is opened on the side of the purification box connected to the outer box.

[0010] Preferably, a pump body is fixedly connected to the top of the purification box, and a first connecting pipe is fixedly connected to one end of the pump body. One end of the first connecting pipe passes through the top side of the purification box and extends into the interior of the purification box.

[0011] Preferably, a second connecting pipe is fixedly connected to the other end of the pump body, and the other end of the second connecting pipe is fixedly connected to a multi-port pipe, with the other ends of the multi-port pipe passing through one side of the outer casing.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the drive motor drives the first connecting rod and the rotating disk to rotate through the belt assembly. The rotating disk rotates in conjunction with the second connecting rod, the second adjusting rod, and the first adjusting rod to realize the angle adjustment of the guide plate. The water flow speed and direction can be controlled according to the needs of different stages such as the fish egg stage and the larval stage, so as to avoid fish egg damage or larval stress caused by water flow impact, improve the adaptability of the hatching environment, and improve the hatching rate and survival rate of fish fry.

[0013] 2. In this utility model, water inside the outer box flows into the purification box through the connecting port. Under the action of gravity, it flows step by step along the inclined first filter plate, second filter plate, and third filter plate, respectively intercepting large particles of uneaten food, medium particles of feces, and fine impurities, thereby improving the water purification effect. The pump body draws clean water from the purification box through the first connecting pipe and delivers it to the multi-port pipe through the second connecting pipe. The multi-port pipe evenly distributes the water back to the outer box, forming a water circulation, ensuring that the hatching water remains clean, providing a stable and high-quality water environment for fish fry hatching, and reducing the risk of disease.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a circulating water purification device for fish fry hatching, including an outer casing 1. A circulating purification mechanism 3 is installed on one side of the outer casing 1, and a hatching mechanism 2 is installed inside the outer casing 1. A flow guiding mechanism 4 is provided above the hatching mechanism 2. The flow guiding mechanism 4 includes a flow guiding plate 41, and rotating rods 42 are fixedly connected to both ends of the flow guiding plate 41. One end of one rotating rod 42 is rotatably connected to the inner side of the outer casing 1, and one end of the other rotating rod 42 passes through the other side of the outer casing 1 and is fixedly connected to a first adjusting rod 43. The other end of the first adjusting rod 43 is rotatably connected to a second adjusting rod 49, and the other end of the second adjusting rod 49 is rotatably connected to... A rotating disk 47 is connected to the outer casing 1. A second connecting rod 48 is fixedly connected to one side of the rotating disk 47, and the other end of the second connecting rod 48 is rotatably connected to the outside of the outer casing 1. A first connecting rod 44 is fixedly connected to the other side of the rotating disk 47. A drive motor 45 is fixedly connected to the outside of the outer casing 1. A belt assembly 46 is installed between the output end of the drive motor 45 and the first connecting rod 44. The incubation mechanism 2 includes a fixing plate 22. Two fixing plates 22 are fixedly connected to the inside of the outer casing 1 on both sides. A positioning plate 23 is inserted into the middle of the two fixing plates 22. An incubation box 21 is fixedly connected to the middle of the positioning plate 23. An opening is provided on the side wall of the incubation box 21.

[0019] The drive motor 45 outputs power, which is transmitted to the first connecting rod 44 via the belt assembly 46, causing the rotating disk 47 to rotate. The rotating disk 47 is driven by the connecting rod of the second connecting rod 48, the second adjusting rod 49, the first adjusting rod 43, and the rotating rod 42, which drives the guide plate 41 to rotate around the rotating rod 42. The angle of the guide plate 41 is adjusted to control the water flow state inside the outer box 1. The water flow speed and direction are adapted to different hatching stages of fish fry to improve the adaptability of the hatching environment and increase the hatching rate of fish fry. The hatching box 21 is fixed inside the outer box 1 by the plug-in structure of the positioning plate 23 and the fixing plate 22. Circulating water can enter and exit through the opening on the side wall of the hatching box 21 to provide dissolved oxygen and clean water for fish fry hatching.

[0020] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the circulating purification mechanism 3 includes a purification box 31. A first filter plate 36, a second filter plate 37, and a third filter plate 38 are fixedly connected inside the purification box 31. The first filter plate 36, the second filter plate 37, and the third filter plate 38 are arranged obliquely inside the purification box 31 in sequence. A communication port 39 is opened on the connection side between the purification box 31 and the outer box 1. A pump body 33 is fixedly connected to the top of the purification box 31. One end of the pump body 33 is fixedly connected to a first connecting pipe 32. One end of the first connecting pipe 32 passes through the top side of the purification box 31 and extends into the interior of the purification box 31. The other end of the pump body 33 is fixedly connected to a second connecting pipe 34. The other end of the second connecting pipe 34 is fixedly connected to a multi-port pipe 35. The other ends of the multi-port pipe 35 pass through one side of the outer box 1.

[0021] After the pump body 33 starts, it draws filtered water from the purification tank 31 through the first connecting pipe 32, and then transports it to the multi-port pipe 35 through the second connecting pipe 34. The multi-port pipe 35 evenly sends the water back into the outer casing 1 to achieve water circulation. The water in the outer casing 1 flows into the purification tank 31 through the connecting port 39, and undergoes multi-stage filtration by passing through the first filter plate 36, the second filter plate 37, and the third filter plate 38 arranged at an inclined angle. The first filter plate 36, as the primary filtration component, uses a stainless steel filter screen with an inclination angle of 30°, mainly intercepting water. For larger solid impurities, the second filter plate 37, as an intermediate filtration component, uses a nylon filter screen with a tilt angle of 25° to intercept medium-sized impurities remaining after the first stage of filtration. The third filter plate 38, as a deep filtration component, uses a non-woven fabric composite activated carbon coating with a tilt angle of 20° to intercept small suspended solids that were not filtered in the first two stages. At the same time, the activated carbon removes some odors and small molecule organic pollutants from the water through adsorption, purifying the water quality. After the water quality is purified, it is pumped out and circulated again by the pump body 33.

[0022] The device is used and works as follows: The pump body 33 draws filtered water from the purification tank 31 through the first connecting pipe 32, and then the water is transported to the multi-port pipe 35 through the second connecting pipe 34. The multi-port pipe 35 distributes the clean water evenly into the outer tank 1 to provide basic water for the hatching area. After the water in the outer tank 1 has nourished the hatching mechanism 2, it flows back to the purification tank 31 through the connecting port 39. Under the action of gravity, the water flows step by step along the inclined first filter plate 36, second filter plate 37, and third filter plate 38. The three-stage filtration intercepts large particles of uneaten feed, medium particles of feces, and fine impurities, respectively, to achieve deep water purification and form a closed-loop water circulation.

[0023] The drive motor 45 operates, driving the first connecting rod 44 and the rotating disk 47 to rotate via the belt assembly 46. The rotating disk 47 rotates the rod 42 in conjunction with the second connecting rod 48, the second adjusting rod 49, and the first adjusting rod 43, causing the guide plate 41 to rotate and adjust its angle, thereby controlling the water flow speed and direction inside the outer casing 1.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
