Description

Technical Field

[0001] This invention relates to the technical field of aquaculture, and more particularly to a water quality control device for disease prevention in aquaculture. Background Technology

[0002] In the aquaculture industry, when breeding fish fry and fingerlings, the high stocking density and weak environmental adaptability of the fry make them prone to diseases. In some deeper aquaculture ponds or reservoirs, due to water stratification, the surface water is relatively oxygenated due to sunlight and wind, while the bottom water is prone to insufficient dissolved oxygen. In areas where fish fry are clustered together, the accumulation of fish feces further aggravates the deterioration of the water quality, which can easily lead to fish diseases.

[0003] In existing technologies, when feeding fish, the fry tend to huddle together near the feeding device to eat. As they feed and defecate near the device, a large amount of fish feces accumulate. Additionally, uneaten feed also tends to accumulate in the feeding area. The accumulation of these pollutants can lead to serious exceedances of chemical oxygen demand, ammonia nitrogen, and nitrite nitrogen in the aquaculture water, affecting the growth and survival of fish, easily causing diseases in the fry, and posing a significant threat to aquaculture.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1, please refer to... Figure 1 and Figure 3 As shown, this invention provides a water quality control device for disease prevention in aquaculture, including a floating plate 3, a feeding box 1, and a collection tray 9. The floating plate 3 is placed on the water surface; the feeding box 1 is installed on the upper part of the floating plate 3, and a sprinkling tray 14 is rotatably connected to the bottom outlet of the feeding box 1. A control baffle 13 is set below the bottom outlet of the feeding box 1 and vertically inserted into the middle of the sprinkling tray 14. Fish feed is put into the inner cavity of the feeding box 1 and discharged through the bottom outlet. The rapidly rotating sprinkling tray 14 sprinkles the fish feed into the pond to feed the fish fry. By controlling the vertical movement of the control baffle 13, the distance between it and the bottom outlet of the feeding box 1 is controlled, thereby adjusting the feeding speed of the fish feed in the feeding box 1, which is convenient for flexible control according to the feeding rate of the fish fry.

[0025] In addition, the collection tray 9 is fixedly connected to the bottom of the floating plate 3 via the connecting pipe 8. Multiple collection ports 10 are provided on the upper part of the collection tray 9. A composite filter screen 11 is installed at the opening of each collection port 10. A spring rod 18 is installed at the bottom of the composite filter screen 11. A pressure detection component is installed at the bottom of the collection port 10 near the composite filter screen 11. A side drain channel 19 is provided on the side wall of each collection port 10 of the collection tray 9. The top and bottom openings of the side drain channel 19 are connected to the inner cavity of the collection port 10. The collection port 10 is connected to a drainage mechanism. In the initial state, the side drain channel 19... The top opening of the filter 9 is located below the composite filter 11. The feed thrown into the water causes the fish fry to compete for it. The fish fry gather near the floating plate 3. The feces produced during the feeding process fall onto the collection plate 9 and gradually fall into the collection port 10. The fish feces that have entered the collection port 10 are extracted and collected by the drainage mechanism, reducing the feces residue in the feeding area. At the same time, the fish feed that the fish fry have not finished eating is also collected and discharged by the collection port 10, further reducing the accumulation of fish feed in the feeding area, which plays a protective role in the aquaculture water body, realizes the water quality regulation of the aquaculture water body, and plays a role in preventing diseases.

[0026] Furthermore, during the feeding process, the fish feed sinks in the water and is consumed by the fry. When too much fish feed is added, the fry cannot finish it in time, causing some of the feed to fall onto the collection tray 9 and be filtered to the top by the composite filter screen 11. Due to the drainage mechanism, the composite filter screen 11 is lowered by the force of the water flow. At this time, the pressure detection component detects the downward movement of the composite filter screen 11 and knows that too much fish feed has been added. Therefore, it controls the baffle 13 to move upward to reduce the feeding rate of fish feed. This reduces fish feed waste and lowers the eutrophication level of the water body, thereby regulating the water quality in the fry feeding area and reducing the occurrence of fry diseases.

[0027] After a large amount of fish feed is filtered at the top of the composite filter 11 and moves downwards, the filtered fish feed is exposed at the top opening of the side drain channel 19. Due to the action of the drainage mechanism, the deposited fish feed is sucked into the collection port 10 through the top opening of the side drain channel 19, and the excess fish feed is discharged. The composite filter 11 is reset under the action of the spring rod 18, thereby realizing continuous detection of the amount of fish feed fed.

[0028] During feeding, the collection tray 9 is positioned below the fry feeding area and above the bottom of the fishpond, which reduces the amount of aquatic plants and silt entering the collection port 10 and reduces the maintenance frequency of the collection tray 9. The composite filter 11 can filter out large impurities such as aquatic plants, and fish feces and melted fish feed can enter the collection port 10 through the composite filter 11, thus centrally treating water pollutants, regulating water quality, and reducing the occurrence of fry diseases.

[0029] Please see Figure 1 The top of the collection tray 9 is recessed, and multiple collection ports 10 are evenly distributed along the upper circumference of the collection tray 9. The connecting pipe 8 is installed in the middle of the collection tray 9, so that the feces and fish feed falling into the collection tray 9 can gradually flow to the collection ports 10 and be collected by the collection ports 10.

[0030] Please see Figure 5 and Figure 7 In this embodiment, the composite filter 11 is configured with two layers, including a coarse filter 16 on the upper layer and a fine filter 17 on the lower layer. A buffer chamber is provided between the coarse filter 16 and the fine filter 17. By setting the composite filter 11 with a double-layer structure, the fine filter 17 is used to filter larger impurities such as aquatic plants to avoid clogging the collection port 10. Fish feces and undissolved fish food pass through the fine filter 17 to reach the coarse filter 16. Undissolved fish food is filtered by the coarse filter 16, and fish feces pass through the coarse filter 16 and enter the collection port 10. When there is a lot of fish food and the composite filter 11 moves downward, the fish food filtered above the coarse filter 16 is drawn into the collection port 10 through the side drain channel 19. This can prevent the composite filter 11 from being easily clogged due to the accumulation of aquatic plants and fish food on top of it.

[0031] Please see Figures 1-2 The feeding tray 14 includes a conical tray and a lever distributed circumferentially along the upper part of the conical tray. The upper part of the conical tray is an outwardly inclined surface. A feeding port 4 is provided between the feeding box 1 and the floating plate 3 on the outer periphery of the feeding tray 14. By setting the feeding tray 14 with an inclined surface structure, the fish feed can fall quickly along the inclined surface. During the rapid rotation and feeding process of the feeding tray 14, most of the fish feed will be concentrated in the area above the collection tray 9. The fish feed is thrown outward by the lever, which can also reduce the problem of fish feed being too concentrated, making it easier for fish fry to eat. At the same time, it is easy to collect fish feces and uneaten fish feed in the feeding area through the collection tray 9.

[0032] Example 2 further optimizes the aquaculture disease prevention and water quality control device provided in Example 1. The difference from Example 1 is that... (Please refer to Example 2 for details). Figures 4-7 The feeding box 1 is equipped with a water quality regulator 2, which is equipped with a water quality control system. The water quality control system includes a feeding control module, a residue detection module, and a residue treatment module. The residue treatment module is connected to the feeding control module and the residue detection module by signal respectively.

[0033] A drive motor with its output end connected to the sprinkling plate 14 is installed on the floating plate 3. A telescopic motor with its output end connected to the regulating baffle 13 is installed on the sprinkling plate 14. The feeding control module is connected to the drive motor and the telescopic motor respectively. When feeding, the feeding control module controls the drive motor to drive the sprinkling plate 14 to rotate and sprinkle fish feed into the fish pond. In addition, the telescopic motor controls the regulating baffle 13 to move up and down to control the feeding rate of fish feed.

[0034] It is worth mentioning that you should refer to Figures 5-6 The pressure detection component includes a detection chamber 21 on the collection tray 9, a slider 22 in the detection chamber 21, a distance sensor 23 in the detection chamber 21, and a multi-link 20 rotatably connected to the bottom of the composite filter 11. The end of the multi-link 20 extends to the detection chamber 21 and is connected to the slider 22. The residual detection module is signal-connected to the distance sensor 23. When the composite filter 11 moves down, it will push the slider 22 to move in the detection chamber 21 through the multi-link 20. The distance sensor 23 detects the position data of the slider 22. When the residual detection module determines that the position data reaches the preset position data, it determines that the fish feed feeding speed is too fast. At this time, the feeding control module executes the reduction command, controls the telescopic motor to work, and drives the regulating baffle 13 to move up to reduce the feeding rate of the fish feed.

[0035] Before the feeding control module executes the reduction command, the residual processing module receives the detection signal from the residual detection module and calculates the number of collection ports 10 corresponding to the judgment that the fish feed dispensing speed is too fast. When the number is greater than or equal to half of the number of collection ports 10, it is judged that the fish feed is dispensing too fast, and the feeding control module executes the reduction command. Conversely, when the number is less than half of the number of collection ports 10, it is judged that the fish feed dispensing is normal. At this time, the fish fry may be concentrated on one side of the feeding area. At this time, the feeding control module executes the slow stop command, stops feeding for a preset time (e.g., 15-30 seconds), and allows the fish fry to spread and then gather again, improving the uniformity of the fish fry distribution.

[0036] In addition, a magnetic metal plate 15 is installed on the side wall of the detection chamber 21 along the moving direction of the slider 22. An electromagnet 24 matching the magnetic metal plate 15 is installed on the slider 22. The residual processing module is connected to the electromagnet 24. When the residual detection module determines that the fish feed is fed too quickly, the feeding control module executes a reduction command. At the same time, the residual processing module controls the electromagnet 24 to be energized for a preset time (e.g., 15-20 seconds). The electromagnet 24 and the magnetic metal plate 15 are magnetically locked. At this time, the position of the composite filter 11 is fixed, so that the side discharge channel 19 can better collect and process the fish feed on the top of the composite filter 11 and avoid clogging the composite filter 11.

[0037] It is worth mentioning that the floating plate 3 is equipped with an upper filter cylinder 5, a filter screen is installed in the middle of the upper filter cylinder 5, and a drain pipe 6 is connected to the bottom of the upper filter cylinder 5. The upper part of the upper filter cylinder 5 is connected to multiple collection ports 10 in the collection tray 9 through a water guide pipe 7. The drainage mechanism includes a water pump, which is installed in series on the collection ports 10. The feeding control module is connected to the water pump signal. During the feeding process, the feeding control module controls the water pump to work and collect fish feces and fish feed in the feeding area through the collection ports 10. After being filtered by the filter screen in the upper filter cylinder 5, the fish feces and fish feed are discharged into the water through the drain pipe 6.

[0038] In addition, the other end of the drain pipe 6 is connected to the feeding chamber 12 in the feeding box 1. A solenoid valve is installed between the drain pipe 6 and the feeding chamber 12. The feeding control module is connected to the solenoid valve. After feeding is completed, the feeding control module controls the water pump to work continuously for a preset time, and at the same time controls the solenoid valve to open. The filtered water enters the feeding chamber 12 to rinse the feeding box 1. At the same time, the rinsing water carries a large amount of oxygen into the fish pond through the action of the rotating spray plate 14, which quickly replaces the water in the feeding area, increases the oxygen content of the water in the area, and reduces the occurrence of fish fry diseases.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
