Description

Technical Field

[0001] The present invention relates to the technical field of fish farming, and particularly relates to a fish farming system based on a deep - water cage. Background Art

[0002] With the development of the economy and the continuous improvement of people's living standards, the demand for marine fishery resources has been increasing continuously, and the fish farming industry has also developed rapidly. Most traditional fish farming is achieved through fish ponds, and most of the fish cultured in fish ponds are freshwater fish. However, with the improvement of people's requirements for different tastes of fish, the types of cultured fish are no longer limited to freshwater fish, but are beginning to develop towards marine fish. In order to facilitate the farming of marine fish, the currently widely used method is deep - water cages. After putting deep - water cages into the sea, marine fish are cultured in the deep - water cages. The culture water in the deep - water cages can be replaced with seawater, so as to provide clean and suitable seawater for the farming of marine fish. For example, a deep - sea cage farming device with the publication number CN208095709U (hereinafter referred to as D1), which includes a rectangular frame, a track frame, a mounting frame, a culture net, a traction mechanism and a cleaning mechanism. The culture net is installed inside the rectangular frame. Mounting frames are symmetrically installed on both sides below the culture net. Four track frames are respectively installed on the inner side edges of the rectangular frame. A transmission seat is installed on the track frame, and the transmission seat is slidably connected to the guide rail on the track frame. A double - shaft motor is installed at the middle position inside the transmission seat. The two output shafts of the double - shaft motor are respectively connected to gears, and the gears are meshed with the racks installed on the track frame. A traction mechanism is installed above the transmission seat. The cleaning mechanism includes a housing, a submersible motor, a transmission frame and a wheel brush. Most of D1 and the deep - water cages in the prior art are difficult to take out after being put in. During long - term use, the outer cover of the deep - water cage may be damaged. After the outer cover of the cage is damaged, the cultured fish may escape, or external fish may enter the cage, ultimately resulting in the death of the cultured fish. However, neither D1 nor the prior art has the function of detecting the damage of the outer cover of the cage, so it is impossible to detect and handle it in time, resulting in an increase in farming costs.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] To better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0027] See Figures 1 to 5 , a fish farming system based on a deep - water cage provided by the present invention includes an annular track 1, a deep - water cage 2, a traveling mechanism, a bearing plate 3, a console 4, and a damage detection mechanism. The annular track 1 is arranged on the sea surface. The traveling mechanism is arranged on the top surface of the bearing plate 3 and is used to travel along the side wall of the annular track 1. The deep - water cage 2 is rotatably arranged on the bottom surface of the bearing plate 3. The damage detection mechanism includes an extension plate 5, a hydraulic rod 6, a first lifting plate 7, a water turbine 8, a first flow velocity sensor 9, an electric sliding table 10, a second lifting plate 11, an electric push rod 12, a rotary motor 13, a gear 14, and a rack 15. The extension plate 5 is arranged on the top surface of the annular track 1, and one end of it extends above the sea surface. The hydraulic rod 6 is arranged on the bottom surface of the extension plate 5, and its output shaft is connected to the top surface of the first lifting plate 7. The water turbine 8 is arranged on the bottom surface of the first lifting plate 7. The electric push rod 12 is embedded inside the bearing plate 3, and its output shaft extends into the deep - water cage 2 and is connected to the top surface of the second lifting plate 11. The electric sliding table 10 is arranged on the bottom surface of the second lifting plate 11. The first flow velocity sensor 9 is arranged on the mover 16 of the electric sliding table 10. The rotary motor 13 is arranged on the bottom surface of the bearing plate 3, and its output shaft is connected to the gear 14. The rack 15 is arranged on the outer wall of the deep - water cage 2 and is distributed in a ring shape. The gear 14 meshes with the rack 15. The console 4 is arranged on the top surface of the annular track 1 and is electrically connected to the traveling mechanism, the hydraulic rod 6, the water turbine 8, the first flow velocity sensor 9, the electric sliding table 10, the electric push rod 12, and the rotary motor 13 respectively. A wireless transceiver 17 is arranged on the console 4.

[0028] After placing the annular track 1 on the sea surface and fixing it, the deep - water cage 2 is installed below the annular track 1 through the traveling mechanism. The traveling mechanism can drive the deep - water cage 2 to travel along the lower part of the annular track 1 through the bearing plate 3, so as to change the position of the deep - water cage 2, and the growth environment of the fish can be adjusted according to the real - time situation of the sea area, providing the most suitable environment for the growth of the fish.

[0029] During the long-term use of the deep-water cage 2, due to external factors and the like, the netting 28 thereof may be damaged, which affects the normal growth of fish. Therefore, the present invention is provided with a damage detection mechanism. An extension plate 5 is provided at one position above the annular track 1. A hydraulic rod 6 is provided below one end of the extension plate 5 away from the center of the annular track 1. The hydraulic rod 6 can drive the water turbine 8 to descend into the water through the first lifting plate 7. The position where the extension plate 5 is located is the damage detection station. When performing damage detection, the carrier plate 3 and the deep-water cage 2 are moved below the extension plate 5 through the traveling mechanism. At the same time, after the water turbine 8 is lowered to one side of the deep-water cage 2, the water turbine 8 is started. The water turbine 8 will generate a water flow flowing towards the deep-water cage 2. A second lifting plate 11 is provided in the deep-water cage 2. An electric slide 10 is provided on the second lifting plate 11. A first flow velocity sensor 9 provided on the slider 16 of the electric slide 10 can detect the flow velocity of the water flow flowing from the outside into the deep-water cage 2. If the netting 28 is damaged, the flow velocity at the damaged part is greater than that at other positions, and this is used as a basis for judging whether the netting 28 is damaged. The first flow velocity sensor 9 is initially located on one side of the water turbine 8. The electric slide 10 can drive the first flow velocity sensor 9 to move horizontally to detect whether the netting 28 on the same horizontal line of the deep-water cage 2 is damaged. At the same time, the hydraulic rod 6 and the electric push rod 12 can respectively drive the first lifting plate 7 and the second lifting plate 11 to descend, so that the water turbine 8 and the first flow velocity sensor 9 descend to different positions for flow velocity detection. Finally, the result of whether the netting 28 is damaged can be obtained. If the netting 28 is damaged, a signal can be sent to remote staff through the wireless transceiver 17 for timely repair.

[0030] In addition, the deep-water cage 2 has multiple side walls, and the side walls are relatively easy to be damaged due to the nibbling of fish or the impact of floating objects. Therefore, when the present invention performs damage detection, all the side walls of the deep-water cage 2 will be detected. A rotary motor 13 is provided on the bottom surface of the carrier plate 3. The rotary motor 13 can drive the gear 14 to rotate. The gear 14 can drive the entire deep-water cage 2 to rotate through the rack 15, so that different side walls of the deep-water cage 2 are located between the first flow velocity sensor 9 and the water turbine 8, facilitating the damage detection of the netting 28 on different sides.

[0031] Preferably, the traveling mechanism includes a U-shaped frame 18, a driving wheel 19, a rotating shaft 20, a dual-shaft motor 21, a synchronous pulley 22, and a synchronous belt 23. The U-shaped frame 18 is disposed on the top surface of the carrier plate 3 with its opening facing upward. The driving wheel 19 is disposed on the side wall of the opening of the U-shaped frame 18. One end of the rotating shaft 20 is connected to the driving wheel 19, and the other end extends into the U-shaped frame 18 and is rotatably connected to the inner wall of the U-shaped frame 18. The dual-shaft motor 21 is disposed in the U-shaped frame 18. The synchronous pulleys 22 are disposed on the rotating shaft 20 and the output shaft of the dual-shaft motor 21. The synchronous belt 23 connects the synchronous pulleys 22. The control console 4 is electrically connected to the dual-shaft motor 21. Grooves 24 are provided on the inner side wall and the outer side wall of the annular track 1. The driving wheel 19 is located in the groove 24.

[0032] The dual-shaft motor 21 can drive the synchronous pulley 22 on its output shaft to rotate, and drive the synchronous pulley 22 on the rotating shaft 20 through the synchronous belt 23, so that the rotating shaft 20 can drive the driving wheel 19 to rotate, and the driving wheel 19 can move in the groove 24 to realize the movement of the carrier plate 3 and the deep-water cage 2.

[0033] Preferably, the traveling mechanism further includes a bearing 25. The bearing 25 is disposed on the inner side wall of the U-shaped frame 18. The rotating shaft 20 is connected to the bearing 25.

[0034] The provided bearing 25 is used for the connection of the rotating shaft 20 to facilitate the rotation of the rotating shaft 20.

[0035] Preferably, the deep-water cage 2 includes a circular frame 26, a rectangular frame 27, and a netting 28. The netting 28 is disposed on the surface of the rectangular frame 27. The circular frame 26 is externally tangent to the outside of the rectangular frame 27. The rack 15 is disposed on the outer circumferential surface of the circular frame 26.

[0036] The netting 28 is provided on all six faces of the rectangular frame 27. The output shaft of the hydraulic rod 6 will directly pass through the upper netting 28 and enter the interior of the rectangular frame 27, and then be connected to the top surface of the second lifting plate 11. When performing the damage detection, the netting 28 on the four side walls of the rectangular frame 27 is mainly detected. The provided circular frame 26 is used for installing the rack 15 to facilitate the rotating motor 13 to drive the rotation of the entire deep-water cage 2 through the gear 14.

[0037] Preferably, a T-shaped block 29 is disposed on the top surface of the circular frame 26, and a T-shaped groove 30 is disposed on the bottom surface of the carrier plate 3. The T-shaped block 29 is located in the T-shaped groove 30.

[0038] To ensure the stability of the rotation of the deep-water cage 2, a T-shaped block 29 is disposed on the top surface of the circular frame 26. When the rotating motor 13 drives the deep-water cage 2 to rotate, the T-shaped block 29 can move in the T-shaped groove 30 to prevent the rotation of the deep-water cage 2 from deviating.

[0039] Preferably, the damage detection mechanism further includes a raised platform 31 which is arranged on the top surface of the annular track 1, and the extension plate 5 is arranged on the raised platform 31.

[0040] The arranged raised platform 31 is used to increase the height of the extension plate 5 so that the water turbine 8 is above the water surface when being retracted upward, avoiding hindering the movement of the deep - water cage 2.

[0041] Preferably, it further includes an environmental monitoring mechanism. The environmental monitoring mechanism includes a moving plate 32, a second flow velocity sensor 33, a dissolved oxygen sensor 34, and an ammonia nitrogen sensor 35. The traveling mechanism is arranged on the top surface of the moving plate 32 and is used to drive the moving plate 32 to move. The second flow velocity sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35 are arranged on the bottom surface of the moving plate 32, and the console 4 is electrically connected to the second flow velocity sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35 respectively.

[0042] There may be certain differences in the water quality at the position below the annular track 1. In order to provide the most suitable environment for fish, the present invention sets an environmental monitoring mechanism. The traveling mechanism is set to be two, and one of them can drive the moving plate 32 to move. During the process of the moving plate 32 moving along the lower part of the annular track 1, the second flow velocity sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35 can collect the flow velocity information, dissolved oxygen content, and ammonia nitrogen content in the ocean. The console 4 judges which position is most suitable for the growth of fish according to the collected data, and then moves the deep - water cage 2 to the corresponding position through the traveling mechanism.

[0043] For the aquaculture of the deep - water cage 2, its flow velocity, dissolved oxygen content, and ammonia nitrogen content all have a certain range. When the data collected by any one of the second flow velocity sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35 is not within the preset range, the corresponding position is not considered.

[0044] Preferably, the console 4 is internally provided with an assignment unit 36, a summation unit 37, a comparison unit 38, and an adjustment unit 39. The assignment unit 36 assigns values to the data collected by the second flow velocity sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35. The summation unit 37 sums up the assigned data. The comparison unit 38 compares the summation results of different positions of the moving plate 32 and sends the position of the moving plate 32 corresponding to the largest summation result to the adjustment unit 39. The adjustment unit 39 drives the traveling mechanism above the moving plate 32 to drive the moving plate 32 to move to the position with the largest summation result.

[0045] After the assignment unit 36 assigns values to the data collected by multiple sensors, the assigned data is summed by the summation unit 37. The summation results at different positions are compared by the comparison result, and finally a maximum value can be obtained. The position corresponding to the maximum value is the most suitable position. The control console 4 can drive the deep-water cage 2 to move to the corresponding position through the traveling mechanism, so as to provide the most suitable breeding environment for fish.

[0046] Preferably, a position unit 40 is further provided in the control console 4. A plurality of trigger buttons 41 are provided on the bottom surface of the groove 24. The trigger buttons 41 are located below the moving path of the driving wheel 19. The position unit 40 is respectively connected to the trigger buttons 41 and the summation unit 37 for data connection.

[0047] When the driving wheel 19 moves in the groove 24, it will trigger the trigger button 41. The control console 4 can determine the position of the sensor according to the signal sent by the trigger button 41. The corresponding position is stored by the position unit 40 and sent to the summation unit 37. When the summation unit 37 outputs the summation result, the summation result will include position information. After finally obtaining the maximum summation result, the adjustment unit 39 can drive the traveling mechanism to drive the deep-water cage 2 to move to the designated position according to the position.

[0048] Preferably, the absolute values of the values assigned by the assignment unit 36 to the second flow rate sensor 33, the dissolved oxygen sensor 34, and the ammonia nitrogen sensor 35 increase in sequence. The value assigned by the assignment unit 36 to the ammonia nitrogen sensor 35 is negative.

[0049] Within a predetermined range, the higher the flow rate, the higher the dissolved amount, and the lower the ammonia nitrogen content, the more suitable it is for the growth of fish. Therefore, when assigning values, the value of ammonia nitrogen is negative, and since the ammonia nitrogen content has a greater impact on the growth of fish, among the absolute values of the assigned values, the value of ammonia nitrogen is the largest.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
