Description

Technical Field

[0001] This utility model relates to the field of Qing Shi Pao Li breeding technology, and in particular to a circulating water purification device for Qing Shi Pao Li breeding. Background Technology

[0002] The green rock lizard is a species of fish belonging to the genus *Symplocos* in the family Symplocidae of the order Siluriformes. It has an elongated body, a flattened head (the length of which is approximately equal to the width of the head), and a laterally compressed posterior body. The green rock lizard has small eyes located above the middle of its head. Its mouth is inferior and transversely slit. Its upper and lower jaws have a band of teeth arranged only at the anterior end of the palatine bone. The teeth are relatively coarse. The green rock lizard is not very active and mainly lives in rock burrows in fast-flowing waters. It attaches itself to rocks using sucker-like fins and primarily feeds on aquatic insects and larvae.

[0003] The blue rock loach is a rare cold-water freshwater fish. Due to habitat destruction, overfishing, and ecological degradation, its wild population has declined sharply. To protect this rare species, artificial breeding and propagation have become key technologies. However, since blue rock loach farming requires continuously flowing clean water, traditional pond or cement pond farming can lead to water quality deterioration, causing diseases such as saprolegniasis and gill rot. Therefore, frequent water changes are necessary, resulting in serious water waste. Furthermore, wastewater discharge may pollute the surrounding environment. At the same time, in high-density farming environments, pathogens are prone to proliferate, and the lack of an effective circulating water treatment system makes it difficult to purify the water and isolate pathogens in real time.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1:

[0031] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a circulating water purification device for the breeding of *Cyprinus spp.*, including a breeding tank 1, a flow guide 2 above the breeding tank 1, a water storage tank 3 at the bottom of the breeding tank 1, a filter assembly 4 inside the water storage tank 3, a vertically arranged water guide pipe 5 connected to the inner wall of the water storage tank 3, and the end of the water guide pipe 5 away from the water storage tank 3 connected to the water inlet end of the flow guide 2, a ramp 6 inside the breeding tank 1, and several sets of partitions 7 fixed on the outer side of the ramp 6.

[0032] The rearing tank 1 is designed for the rearing of *Cetacea esculenta*. It should be noted that the rearing tank 1 consists of a frame and a glass panel, allowing observation of the interior from the outside. The spiral structure of the flow guide 2 utilizes gravity to guide the water flow naturally, reducing power consumption and extending the water flow path, thus improving purification and oxygenation efficiency. The filter assembly 4 filters the water in the rearing tank 1 through its internal structure, removing uneaten food, feces, and harmful substances, maintaining water quality. The water quality is stable. Since one end of the water pipe 5 is connected to the inner wall of the water storage tank 3, and the other end of the water pipe 5 is connected to the water inlet of the guide frame 2, the filtered water can be reintroduced into the breeding tank 1, thereby achieving the purpose of water circulation. Since several sets of baffles 7 are set on the outside of the slope plate 6, and the baffles 7 are designed in a cross pattern, when the water flows on the surface of the slope plate 6 by gravity, the circulating water system simulates the flow state of a natural river, which satisfies the biological characteristic of the Qing Shi Pao Li (a type of catfish) that "likes flowing water" and promotes its normal feeding and growth.

[0033] The filter assembly 4 includes a water pump 41 disposed on one side of the water storage tank 3. The water storage tank 3 is equipped with three sets of filter cylinders 42. The ends of the three sets of filter cylinders 42 near the water pump 41 are all connected to the water outlet of the water pump 41. The ends of the three sets of filter cylinders 42 away from the water pump 41 are all connected to a drain pipe 43. The end of the drain pipe 43 away from the filter cylinders 42 penetrates the inner wall of the water storage tank 3 and extends to the outside of the water storage tank 3.

[0034] Since the water supply pipe 45 connected to the water inlet of the water pump 41 is connected to the breeding tank 1, when the water pump 41 is started, the water pump 41 can transport the water in the breeding tank 1 to the filter cylinder 42 through the water supply pipe 45. At the same time, since the inner wall of the filter cylinder 42 has several holes, it can filter the uneaten feed, feces and harmful substances in the water. The filtered water will fall into the water storage tank 3 through the holes in the inner wall of the filter cylinder 42. At this time, the uneaten feed, feces and harmful substances in the water will remain in the filter cylinder 42. Since the sewage pipe 43 runs through the inner wall of the water storage tank 3 and extends to the outside of the water storage tank 3, and is connected to one end of the filter cylinder 42, the uneaten feed, feces and harmful substances in the filter cylinder 42 can be discharged through the sewage pipe 43.

[0035] The filter assembly 4 also includes a first valve 44 located outside the drain pipe 43, and the water inlet end of the water pump 41 is connected to a water supply pipe 45, with the end of the water supply pipe 45 away from the water pump 41 connected to the inner wall of the breeding tank 1.

[0036] Since the first valve 44 is located outside the drain pipe 43, the first valve 44 can control the opening and closing of the drain pipe 43. Since one end of the water supply pipe 45 is connected to the water inlet of the water pump 41, and the other end of the water supply pipe 45 is connected to the bottom of the breeding tank 1, the water in the breeding tank 1 can be transported to the filter cartridge 42 when the water pump 41 is started.

[0037] Example 2:

[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the top of the breeding box 1 is equipped with two cabinet doors 8, and the inner walls of the two cabinet doors 8 are provided with several sets of ventilation openings 9.

[0040] The two cabinet doors 8 can seal the opening of the breeding box 1, and the inner wall of the cabinet doors 8 has ventilation holes 9, so the breeding box 1 can be ventilated.

[0041] Specifically, a fixed frame 10 is fixed to the top of the breeding box 1, and two sets of diagonal bracing plates with symmetrical design are fixed to the inner wall of the fixed frame 10. A fixed plate 11 is fixed to one side of the fixed frame 10, and the outer side of the fixed plate 11 is fixedly connected to the outer side of the flow guide frame 2.

[0042] The fixing frame 10 is fixed to the top of the breeding box 1, serving as the core support structure and providing a stable installation base for other related components. It ensures that the components fixed on it can be stably positioned at the top of the breeding box 1, preventing the normal operation of the entire breeding system from being affected by component shaking or displacement. The two sets of symmetrically designed diagonal bracing plates fixed to the inner wall of the fixing frame 10 mainly enhance the structural strength and stability of the fixing frame 10. By changing the force transmission path, the diagonal bracing plates distribute the vertical and horizontal forces borne by the fixing frame 10 to a larger structural range, reducing the situation of excessive local stress on the fixing frame 10, thereby preventing the fixing frame 10 from deforming or being damaged. The fixing plate 11 is fixed to one side of the fixing frame 10, and its outer side is fixedly connected to the outer side of the flow guide 2, acting as a bridge connecting the fixing frame 10 and the flow guide 2. It firmly fixes the flow guide 2 to the fixing frame 10, allowing the flow guide 2 to be accurately installed at a suitable position on the top of the breeding box 1 to achieve the flow guiding function.

[0043] Specifically, the inner wall of the breeding box 1 is provided with a longitudinally arranged fence 12, and the inner wall of the breeding box 1 is provided with a groove 13, and the groove 13 is located at the connection between the water supply pipe 45 and the breeding box 1.

[0044] The fence 12 can shield the rock bream inside the breeding tank 1, while not blocking uneaten food, feces and harmful substances in the water. It can prevent the rock bream from being sucked into the connection between the water pipe 45 and the breeding tank 1, thus preventing damage to the rock bream. The groove 13 allows the water in the breeding tank 1 to flow fully into the water pipe 45.

[0045] Specifically, a protective cover 14 is fixed to the inner wall of the groove 13, and the inner wall of the protective cover 14 is provided with several component through holes 15.

[0046] The protective cover 14 can disperse the suction force of the water supply pipe 45 on the water in the breeding tank 1, preventing the device from sucking the blue stone catfish into the connection between the water supply pipe 45 and the breeding tank 1 when filtering the water. At the same time, the large size of the through hole 15 will not isolate the uneaten feed, feces and harmful substances in the water.

[0047] Example 3:

[0048] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the inner wall of the breeding box 1 is connected to two sets of drainage pipes 16, and a second valve 17 is installed on the outer side of each set of drainage pipes 16.

[0050] Since the drain pipe 16 is connected to the bottom of the breeding tank 1, the water in the breeding tank 1 can be discharged when the second valve 17 on the outside of the drain pipe 16 is opened.

[0051] Specifically, a support plate 18 is fixed on one side of the water storage tank 3, and the top of the support plate 18 is fixedly connected to the bottom of the water pump 41. Two sets of support legs 19 are provided at the bottom of the breeding tank 1, and connecting frames are fixed on the inner walls of the two sets of support legs 19.

[0052] The support plate 18 is fixed to one side of the water storage tank 3, and its top is fixedly connected to the bottom of the water pump 41. It plays the role of supporting and fixing the water pump 41, ensuring that the water pump 41 can remain stable during operation and will not be displaced or tilted due to vibration or other external forces, thereby ensuring the normal and stable operation of the water pump 41. The two sets of support legs 19 at the bottom of the breeding box 1 mainly play the role of supporting the breeding box 1, raising the breeding box 1 a certain height off the ground, and avoiding the breeding box 1 from direct contact with the ground and being affected by ground moisture, dirt, etc. The connecting frame fixed to the inner wall of the support leg 19 further enhances the structural strength and stability of the support leg 19, so that the entire breeding box 1 can be placed more firmly on the ground.

[0053] When purifying the water in the breeding tank 1 during the breeding of *Cyprinus spp.*, the water pump 41 is first started. The water pump 41 transports the water from the breeding tank 1 to the filter cylinder 42 through the water pipe 45. Since the inner wall of the filter cylinder 42 has several holes, it can filter out uneaten feed, feces, and harmful substances in the water. The filtered water falls into the storage tank 3 through the holes in the inner wall of the filter cylinder 42. At this time, the uneaten feed, feces, and harmful substances in the water remain in the filter cylinder 42. The filtered water is then transported back to the guide frame 2 through the water pipe 5 connected to the inner wall of the storage tank 3. The guide frame 2 uses gravity to... The device guides the water flow naturally, reducing power consumption and extending the water flow path to improve purification and oxygenation efficiency. When the water flows outside the slope plate 6, the partition plate 7 fixed to the outside of the slope plate 6 can simulate the flow state of a natural river, satisfying the biological characteristic of the Chinese rock loach that "prefers flowing water" and promoting its normal feeding and growth. When it is necessary to clean the residual feed, feces and harmful substances in the filter cylinder 42 after long-term use, it is only necessary to open the first valve 44 connected to the outside of the sewage pipe 43 at one end of the filter cylinder 42. At this time, the sewage pipe 43 can discharge the residual feed, feces and harmful substances in the filter cylinder 42, which improves the convenience of the device.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
