Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an ecological pond aquaculture system for tilapia. Background Technology

[0002] Tilapia is an important farmed and export-oriented fish species in my country, with an annual production of around 1.7 million tons. It can be farmed in southern, southwestern, central-eastern, and northern my country. Currently, tilapia farming mainly uses pond culture, followed by intensive farming. Pond culture is primarily intensive farming, which is a high-density, high-input farming model, sometimes reaching a density of 8,000-10,000 fish per acre.

[0003] Tilapia grow quickly, have a large appetite, and a fast metabolism, resulting in a large amount of waste floating in the water. This means that tilapia are constantly living in ponds filled with uneaten food and feces during the farming process, and this problem worsens as the fish grow and the amount of food they are fed increases. Tilapia are omnivorous but can also passively filter-feed on plankton and suspended organic matter. The uneaten food and feces ferment and decompose in the pond, often leading to digestive and liver diseases when ingested by the tilapia, especially during hot seasons, causing persistent illness and mass fish deaths.

[0004] Therefore, there is an urgent need in this field for a new type of tilapia ecological pond aquaculture system to solve the above problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this invention is to provide a tilapia ecological pond aquaculture system to solve the problems existing in the prior art. It can effectively remove impurities in the water within the main body of the pond, thereby improving the living environment of tilapia.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-7 As shown, this embodiment provides a tilapia ecological pond aquaculture system, including a pond body 1, a pond aquaculture area 2, an aquaculture water inlet area 3, a pond water diversion channel 5, and a pond catcher 6. The pond aquaculture area 2 has an inlet surface and an outlet surface, which are arranged opposite to each other. The outlet surface of the pond aquaculture area 2 is equipped with an outlet mesh 201, and the inlet surface of the pond aquaculture area 2 is equipped with an inlet mesh 203. Both the outlet mesh 201 and the inlet mesh 203 are common meshes, and their function is to prevent the farmed fish in the pond aquaculture area 2 from escaping. Water in pond aquaculture area 2 is connected to water in pond body 1 via aquaculture area outlet screen 201 and aquaculture area inlet screen 203. It should be noted that the aperture of aquaculture area outlet screen 201 and aquaculture area inlet screen 203 is smaller than the size of the farmed fish (i.e., tilapia) in pond aquaculture area 2, thus preventing the farmed fish from passing through these screens. Aquaculture inlet area 3 is located adjacent to the inlet surface of pond aquaculture area 2 and is connected to pond aquaculture area 2 via aquaculture area inlet screen 203. Simultaneously, aquaculture inlet area 3 is connected to water in pond body 1. A flushing device 4 is installed in aquaculture inlet area 3, which drives water from aquaculture inlet area 3 into pond aquaculture area 2, thereby ensuring that the water flow direction in pond body 1 remains constant. One end of the pond water diversion channel 5 is adjacent to the aquaculture area outlet screen 201. Water from the aquaculture area 2 flows into the pond water diversion channel 5 through the aquaculture area outlet screen 201. The other end of the pond water diversion channel 5 is adjacent to the pond scooper 6. Water flowing out of the aquaculture area outlet screen 201 flows into the pond scooper 6 through the pond water diversion channel 5. The pond scooper 6 is used to collect impurities in the water transported by the pond water diversion channel 5.

[0034] In actual use, driven by the flushing device 4, the water in the aquaculture inlet area 3 is transported to the pond aquaculture area 2. The water in the pond aquaculture area 2 and the impurities in the water (including but not limited to uneaten feed, feces, etc.) flow from the inlet surface to the outlet surface. Finally, the water in the aquaculture inlet area 3 and the impurities in the water flow out from the outlet screen 201 of the aquaculture area and are transported to the pond scooper 6 through the pond water guide channel 5. The pond scooper 6 removes the impurities in the water and collects them. The remaining water falls back into the pond body 1 and flows back to the aquaculture inlet area 3, thus completing a water cycle.

[0035] In this embodiment, the pond aquaculture area 2 has a side panel on both sides of its inlet and outlet surfaces. The two side panels, the inlet surface, and the outlet surface together enclose the pond aquaculture area 2. The area of ​​the pond aquaculture area 2 is 1 / 6 to 1 / 5 of the area of ​​the main pond 1. The two side panels are side panels, i.e., sealed plate structures, so the water in the main pond 1 cannot communicate with the water in the pond aquaculture area 2 through the side panels. The outlet surface of the pond aquaculture area 2 also has two aquaculture area outlet panels 202, which are respectively arranged on both sides of the aquaculture area outlet grid 201. Further, from... Figure 2 As can be seen, the two aquaculture zone outlet panels 202 are inclined, making the entire outlet surface resemble an isosceles trapezoid. This design allows the water flowing out of pond aquaculture zone 2 to collect more quickly at the outlet mesh 201. Pond aquaculture zone 2 has multiple inlet mesh 203s and multiple inlet panels 204. Figure 2 The aquaculture zone is equipped with three aquaculture zone inlet screens 203 and four aquaculture zone inlet panels 204. The aquaculture zone inlet screens 203 are used for water passage, while the aquaculture zone inlet panels 204 cannot pass water. The aquaculture zone inlet screens 203 and aquaculture zone inlet panels 204 are arranged alternately. Of course, those skilled in the art can adjust the specific number and distribution of the aquaculture zone inlet screens 203 and aquaculture zone inlet panels 204 according to actual needs, and are not limited to this one method.

[0036] In addition, both the pond aquaculture area 2 and the main pond 1 are planted with plants, including but not limited to one or more of the existing floating plants, submerged plants or emergent plants, to improve water quality and reduce mortality by 70%.

[0037] In this embodiment, the aquaculture water intake area 3 includes two parallel water intake area barriers 301. The water intake area barriers 301 are parallel to the side panel of the pond aquaculture area 2. One end of the water intake area barriers 301 is connected to the water intake surface of the pond aquaculture area 2, and the other end of the water intake area barriers 301 is connected to the pond embankment of the pond body 1 (the pond embankment can be understood as the edge of the pond body 1). The area enclosed by the water intake surface of the pond aquaculture area 2, the pond embankment of the pond body 1, and the two water intake area barriers 301 is the aquaculture water intake area 3. The water intake area barriers 301 can effectively prevent aquatic plants and other debris from entering the aquaculture water intake area 3.

[0038] In this embodiment, as Figures 4-5 As shown, the flushing device 4 includes a cylindrical flushing cylinder 401, with a flushing float 402 fixed on each side of the flushing cylinder 401. A flushing main shaft 404 is rotatably connected to the center of the flushing cylinder 401. The flushing main shaft 404 is equipped with several porous impellers 406 and several helical impellers 407, which are staggered along the axial direction of the flushing main shaft 404. Each porous impeller 406 includes three or more circumferentially distributed porous blades, and each porous blade has multiple water passage holes. Each helical impeller 407 includes three or more circumferentially distributed helical blades. A flushing motor 403 is connected to one end of the flushing main shaft 404, which drives the flushing main shaft 404 to rotate. As the main shaft 404 rotates, the porous impeller 406 mixes water and air thoroughly to achieve oxygenation, while the spiral impeller 407 serves the dual purpose of oxygenation and water propulsion, pushing the oxygen-rich water into the pond aquaculture area 2.

[0039] In this embodiment, as Figure 5 As shown, the two ends of the flushing spindle 404 are connected to the flushing cylinder 401 through a spindle retainer 405.

[0040] Regarding the specific structure of the main shaft retainer 405, the main shaft retainer 405 includes an outer ring structure, multiple main shaft support rods, and a main shaft bearing, wherein the outer ring structure is a circular ring structure. Each main shaft retainer 405 includes three main shaft support rods. One end of the main shaft support rod is fixedly connected to the inner wall of the outer ring structure, and the other end of the main shaft support rod is connected to the outer ring of the main shaft bearing. The three main shaft support rods are evenly distributed circumferentially within the annular space between the outer ring structure and the main shaft bearing. The inner ring of the main shaft bearing is connected to the side wall of the flushing main shaft 404. The rotational connection between the flushing main shaft 404 and the flushing cylinder is achieved through the setting of the main shaft bearing. The outer ring structure is fixed to the inner wall of the flushing cylinder 401 by welding.

[0041] In this embodiment, a support pile is provided at the bottom of the aquaculture water inlet area 3, and the flushing cylinder 401 is fixed to the upper end of the support pile.

[0042] In order to fix the flushing motor 403, a motor fixing cylinder 408 is fixed to one end of the flushing cylinder 401. The flushing motor 403 is fixed to the end of the motor fixing cylinder 408 away from the flushing cylinder 401. The cross-sectional area of ​​the motor fixing cylinder 408 gradually decreases along the direction from the flushing cylinder 401 to the flushing motor 403.

[0043] In this embodiment, the pond water channel 5 includes a water channel net body 501 with a U-shaped cross-section. Multiple water channel support rods 502 are fixed to the lower end of the water channel net body 501 to ensure that the lower end of the water channel net body 501 does not contact the bottom of the pond body 1. In actual use, the lower middle part of the water channel net body 501 is submerged in water, while the upper end of the water channel net body 501 is above the water surface. Furthermore, the mesh size of the water channel net body 501 is smaller than the size of impurities (i.e., uneaten food, feces, etc.). This arrangement ensures that during the transport process, the water in the water channel net body 501 connects with the water in the pond body 1, but the impurities in the water channel net body 501 do not enter the interior of the pond body 1. Instead, they are transported to the pond scooper 6 by the water flow.

[0044] In this embodiment, the pond dredging device 6 includes a conveying device and a scraper body 606. The conveying device is used to transport water from the pond water channel 5 to the scraper body 606, while the scraper body 606 is used to scrape off and collect impurities from the conveying device.

[0045] In this embodiment, as Figure 6 As shown, the conveying device includes a salvage drive roller 601 and a salvage driven roller 602, which are connected by a salvage transmission belt 603. One end of the salvage drive roller 601 is connected to a salvage motor. The salvage driven roller 602 is closer to the pond's water channel 5 than the salvage drive roller 601, and is located below the pond's water channel 5. The scraper body 606 is located below the salvage drive roller 601.

[0046] When the retrieval motor is started, it drives the retrieval drive roller 601 to rotate, thereby driving the retrieval transmission belt 603 and the retrieval driven roller 602 to run. When the pond water channel 5 delivers water and impurities to the pond retrieval device 6, most of the water and impurities flow onto the retrieval transmission belt 603 and are transported to the scraper body 606.

[0047] Furthermore, to secure the active salvage roller 601 and the driven salvage roller 602, an active roller support 604 and a driven roller support 605 are also provided. The two ends of the active salvage roller 601 are rotatably connected to the active roller support 604 via bearings, and the salvage motor is also fixed to the active roller support 604. The active roller support 604 can be fixed to the bank with screws. The driven salvage roller 602 is rotatably connected to the driven roller support 605 via bearings, and the driven roller support 605 is fixed to the bottom of the pond body 1.

[0048] In addition, to further adsorb impurities, a layer of filter cotton, preferably a highly elastic filter cotton such as polyester fiber filter cotton, can be fixed on the surface of the transmission belt. When most of the water and impurities in the water are transported to the salvage transmission belt 603, the water is absorbed into the filter cotton, while the impurities, due to their larger size, adhere to the surface of the filter cotton.

[0049] In this embodiment, as Figure 7 As shown, the scraper body 606 includes a scraper collection box 6062, which is a box structure with an open top. A scraper blade 6061 is fixed to the long side of the scraper collection box 6062 near the retrieval drive roller 601. The upper end of the scraper blade 6061 can contact the filter cotton on the retrieval conveyor belt 603 to scrape off impurities on the retrieval conveyor belt 603. Furthermore, the scraper blade 6061 can be an existing rubber scraper or a silicone scraper to avoid damaging the retrieval conveyor belt 603 and the filter cotton on it.
