Description

Technical Field

[0001] The present invention relates to the field of marine aquaculture technology, and in particular to marine ranch aquaculture equipment and aquaculture method. Background Art

[0002] Marine ranching equipment is primarily used in the ocean for aquatic aquaculture. Current marine ranching equipment is typically used in shallow or nearshore waters and requires manual feeding. This labor-intensive process places the animals under constant stress, leading to increasingly severe diseases, poor product quality, and significant pollution. Consequently, existing marine ranching equipment often utilizes automated bait trapping. However, some existing marine ranching equipment that doesn't require manual feeding still presents challenges.

[0003] For example, Chinese patent publication number CN113749028B discloses marine ranching equipment comprising: a pen secured to the seabed and defining a space for cultivating aquatic organisms; a bait trapping device comprising at least one trapping light assembly comprising multiple trapping lights spaced apart and emitting light to attract marine bait; and a controller electrically connected to each trapping light. This marine ranching equipment is capable of communicating with the marine ecosystem, guiding marine bait into the pen for feeding the aquatic organisms. This allows for natural aquaculture, improves the quality of the aquatic organisms, and reduces labor intensity, making it suitable for large-scale aquaculture.

[0004] The above-mentioned breeding method of trapping bait in a natural state has low pollution and high-quality breeding products. However, the marine ranch breeding equipment uses a combination of a trapping light and a circle through which the bait can pass freely. When the trapping light that is not directly above the circle is turned on, the bait in the circle will also be trapped and escape from the circle, affecting the trapping effect. Moreover, since the bait can pass through the circle, the bait is easy to flow out of the circle when the seawater flows more, affecting the growth of marine organisms, and has low practicality. Therefore, this application provides marine ranch breeding equipment and breeding methods to meet the needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide marine ranch aquaculture equipment and aquaculture method to solve the problem that bait can pass freely in existing enclosures, affecting the growth of aquacultured organisms.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] Marine ranching aquaculture equipment includes a mounting frame, a fry trapping light assembly, a biological bait trapping light assembly, a fixed filter, a flexible movable filter, a drive mechanism, and a separation mechanism. The fixed filter is fixed to opposite sides of the mounting frame, and the mounting frame has a first through-hole and a second through-hole at each end. One end of the flexible movable filter is fixedly connected to the first through-hole, and both sides of the flexible movable filter slide against the inner sidewall of the fixed filter. The other end of the flexible movable filter slides to the second through-hole. The drive mechanism is mounted on the mounting frame corresponding to the upper end of the second through-hole and is used to drive one end of the flexible movable filter to move up and down.

[0008] The inner cavity of the mounting frame is provided with a first area close to the fixed end of the flexible movable filter and a second area close to its movable end. The partition mechanism is arranged perpendicular to the direction of the first through-opening, and the partition mechanism is slidably connected to the middle part of the mounting frame to separate the first area and the second area. The fry trapping light group is installed on the mounting frame corresponding to the first area; the biological bait trapping light group is installed on the mounting frame corresponding to the second area.

[0009] Preferably, the driving mechanism includes a pair of first mounting seats installed on both sides of the mounting frame, one end of the flexible movable filter is fixedly connected to a first connecting shaft, both ends of the first connecting shaft are fixedly connected to a first connecting block, a first motor is installed on the top of a pair of first mounting seats, a first screw rod is rotatably connected to a pair of first mounting seats, and the output end of the first motor is linked to the first screw rod, and the first connecting block is threadedly connected to the first screw rod.

[0010] Preferably, a first sliding groove is provided on the first mounting seat, and both ends of the first connecting shaft are slidably connected to the first sliding groove respectively.

[0011] Preferably, the separation mechanism includes a pair of second mounting seats installed on both sides of the mounting frame, a second connecting shaft is fixedly connected to the middle position of the flexible movable filter, both ends of the second connecting shaft are fixedly connected to second connecting blocks, a second motor is installed on the top of a pair of second mounting seats, a second screw rod is rotatably connected to a pair of second mounting seats, and the output end of the second motor is linked to the second screw rod, and the second connecting block is threadedly connected to the second screw rod.

[0012] Preferably, a second sliding groove is provided on the second mounting seat, and both ends of the second connecting shaft are slidably connected in the second sliding groove respectively.

[0013] Preferably, the flexible movable filter screen is a mesh-shaped flexible filter funnel structure with openings on both sides corresponding to the fixed filter screen.

[0014] Preferably, a plurality of third sliding grooves are provided on both sides of the mounting frame, a plurality of sliders are fixedly connected to both sides of the flexible movable filter, and the sliders are slidably connected in the third sliding grooves.

[0015] Preferably, a plurality of guide rods are provided on the mounting frame for limiting the position of the flexible movable filter screen when the driving mechanism or the separating mechanism drives the flexible movable filter screen to move.

[0016] Preferably, a plurality of photometric sensors are installed on the top of the mounting frame, and an aerator is installed inside the mounting frame.

[0017] The marine ranch farming method includes the following steps: first, installing the equipment. First, the mounting frame is installed in a shallow beach or nearshore waters. Then, the separating mechanism is activated. The second motor drives the second screw to rotate, thereby driving the second connecting block to move to the bottom, so that the entire flexible movable filter is laid on the bottom of the mounting frame. Then, the first motor is activated to drive the first screw to rotate, thereby driving the first connecting block to move to the top, and driving the middle portion of the flexible movable filter to move to the top. At this time, the mounting frame, the fixed filter, and the flexible movable filter cooperate to form an enclosure farming space.

[0018] Step 2: Transitional culture. After the enclosure culture space is formed in step 1, the fry are placed in the culture space and then artificially added with feed for transitional culture. The number of days for transitional culture with artificial feed addition is set, and the number of days for transitional culture is determined according to the stress response time of the cultured organisms.

[0019] Step three, trapping and breeding. After transition breeding, start the fish fry trapping light group, and make the fish fry approach the first through-hole through the phototaxis of the fish. When all the fry are close to the first through-hole, start the separation mechanism, and drive the second connecting shaft to rise by the second motor, so that the second connecting shaft drives the middle part of the flexible movable filter to rise until the second connecting shaft rises to the highest point. At this time, the middle part of the flexible movable filter is separated from the sea surface, thereby dividing the enclosure breeding space formed in step one into two independent breeding spaces, and the fry are concentrated in the first breeding space, and then start the drive mechanism. The first motor is used to drive the first connecting shaft to move upward, so that the bait is captured in the second breeding space. The separation mechanism is then activated, and the second connecting shaft is driven downward by the second motor, so that the two breeding spaces are connected, so that the bait comes into contact with the fry, and the fry are automatically provided with bait.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, the fish fry trapping lamp group, the biological bait trapping lamp group, the driving mechanism and the separating mechanism cooperate, and the phototaxis of the fish fry and the bait is utilized to realize automatic trapping of the bait, and the apertures of the filter holes of the fixed filter and the flexible movable filter are both smaller than the bait size. Therefore, the bait already in the breeding space will not escape from the breeding space due to the influence of the biological bait trapping lamp group, ensuring that the internal bait will not escape, and at the same time achieving the purpose of trapping the external bait, with good trapping effect and easy use.

[0022] When trapping bait, firstly, the brightness of the external environment is sensed by the light sensor. When the brightness is sensed to be dark and suitable for trapping bait, the fry trapping light group is started. The fry in the marine ranch breeding equipment are moved closer to the bottom of the fry trapping light group through the phototaxis of the fry. At this time, the fry are concentrated at a position close to the first through-hole. Then the separation mechanism is started to divide the marine ranch breeding equipment into two independent breeding spaces. At this time, the fry are concentrated in the breeding space below the fry trapping light group. Then the biological bait trapping light group is started. The external bait is moved closer to the bottom of the biological bait trapping light group through the phototaxis of the bait. At the same time, the driving mechanism is started to move the first connecting shaft to the bottom, thereby causing one end of the flexible movable filter to drop below the water surface. At this time, the second through-hole The opening is opened, so that the bait in the ocean enters the marine ranch breeding equipment through the second through-opening, so that the bait moves toward the bottom of the biological bait trapping lamp group. When there is enough bait under the biological bait trapping lamp group, the driving mechanism is started again to drive the first connecting shaft to move to the top, thereby causing one end of the flexible movable filter to rise above the water surface, thereby achieving the purpose of trapping the bait. Then, the separating mechanism is started to cause the second connecting shaft to descend, thereby causing the middle position of the flexible movable filter to descend to the bottom and penetrate into the sea water. At this time, the two independent breeding spaces are connected, providing sufficient bait for the fry, thereby achieving the purpose of automatic breeding, and achieving the purpose of automatically trapping external bait while ensuring that the internal bait does not escape. It is highly practical and easy to use.

[0023] By using this marine ranch farming method, transitional farming is first carried out before automatic marine trapping farming to improve the adaptability of the farmed organisms. By using an aerator in the farming process, concentrated farming can prevent the farmed organisms from suffering from hypoxia, thereby further improving the adaptability of the farmed organisms in marine farming.

The separating mechanism 7 is arranged perpendicular to the direction of the first through-opening, and the separating mechanism 7 is slidably connected to the middle part of the mounting frame 1, and is used to separate the first area and the second area. The fry trapping light group 2 is installed on the corresponding On the mounting frame 1 of the first area; the biological bait trapping lamp group 3 is installed on the mounting frame 1 corresponding to the second area, and through the cooperation of the fry trapping lamp group 2, the biological bait trapping lamp group 3, the driving mechanism 6 and the separating mechanism 7, the phototaxis of the fry and the bait is utilized to realize automatic trapping of the bait, and the apertures of the filter holes of the fixed filter 4 and the flexible movable filter 5 are both smaller than the size of the bait, so the bait already in the breeding space will not escape from the breeding space due to the influence of the biological bait trapping lamp group 3, ensuring that the internal bait will not escape, and at the same time achieving the purpose of trapping the external bait, with good trapping effect and convenient use.

[0042] like Figure 1-6As shown, the driving mechanism 6 includes a pair of first mounting seats 61 installed on both sides of the mounting frame 1, one end of the flexible movable filter 5 is fixedly connected to the first connecting shaft 62, both ends of the first connecting shaft 62 are fixedly connected to the first connecting block 64, the top of the pair of first mounting seats 61 are both installed with a first motor 65, the pair of first mounting seats 61 are rotatably connected to the first screw rod 66, and the output end of the first motor 65 is linked to the first screw rod 66, and the first connecting block 64 is threadedly connected to the first screw rod 66, and a first sliding groove 63 is opened on the first mounting seat 61, and the two ends of the first connecting shaft 62 are respectively slidably connected to the first sliding groove 63; The partition mechanism 7 includes a pair of second mounting seats 71 installed on both sides of the mounting frame 1, a second connecting shaft 72 is fixedly connected to the middle position of the flexible movable filter 5, and second connecting blocks 74 are fixedly connected to the two ends of the second connecting shaft 72.

A second slide groove 73 is opened on the second mounting seat 71, and the two ends of the second connecting shaft 72 are respectively slidably connected to the second slide groove 73.

[0043] When trapping bait, first, the brightness of the external environment is sensed by the photometric sensor. When the brightness is sensed to be dark and suitable for trapping bait, the fry trapping lamp group 2 is started. The fry are attracted to the light, so that the fry in the marine ranch breeding equipment are close to the bottom of the fry trapping lamp group 2. At this time, the fry are concentrated at a position close to the first through-hole. Then the partition mechanism 7 is started to divide the marine ranch breeding equipment into two independent breeding spaces. At this time, the fry are concentrated in the breeding space below the fry trapping lamp group 2. Then the biological bait trapping lamp group 3 is started. The external bait is attracted to the bottom of the biological bait trapping lamp group 3 through the phototaxis of the bait. At the same time, the driving mechanism 6 is started to move the first connecting shaft 62 to the bottom, thereby causing one end of the flexible movable filter screen 5 to drop below the water surface. At this time, the second through-hole The opening is opened, so that the bait in the ocean enters the marine ranch breeding equipment through the second through-opening, so that the bait moves the bait closer to the bottom of the biological bait trapping lamp group 3. When there is enough bait below the biological bait trapping lamp group 3, the driving mechanism 6 is started again to drive the first connecting shaft 62 to move to the top, thereby causing one end of the flexible movable filter screen 5 to rise above the water surface, thereby achieving the purpose of trapping the bait. Then, the separating mechanism 7 is started to cause the second connecting shaft 72 to descend, thereby causing the middle position of the flexible movable filter screen 5 to descend to the bottom and penetrate into the sea water. At this time, the two independent breeding spaces are connected, providing sufficient bait for the fry, thereby achieving the purpose of automatic breeding, and achieving the purpose of automatically trapping external bait while ensuring that the internal bait does not escape. It is highly practical and easy to use.

[0044] like Figure 7As shown, the marine ranch farming method includes step 1, equipment installation. First, the mounting frame 1 is installed in a shallow beach or nearshore waters. Then, the separation mechanism 7 is started, and the second motor 75 drives the second screw rod 76 to rotate, thereby driving the second connecting block 74 to move to the bottom, so that the entire flexible movable filter screen 5 is laid on the bottom of the mounting frame 1. Then, the first motor 65 is started to drive the first screw rod 66 to rotate, thereby driving the first connecting block 64 to move to the top, and driving the middle part of the flexible movable filter screen 5 to move to the top. At this time, the mounting frame 1, the fixed filter screen 4 and the flexible movable filter screen 5 cooperate to form an enclosure farming space.

[0045] Step 2: Transitional culture. After the enclosure culture space is formed in step 1, the fry are placed in the culture space and then artificially added with feed for transitional culture. The number of days for transitional culture with artificial feed addition is set, and the number of days for transitional culture is determined according to the stress response time of the cultured organisms.

[0046] Step three, trapping and breeding. After transition breeding, start the fry trapping light group 2. Through the phototaxis of the fish, the fry are made to approach the first through-hole. When all the fry are close to the first through-hole, start the separation mechanism 7. The second motor 75 drives the second connecting shaft 72 to rise, so that the second connecting shaft 72 drives the middle part of the flexible movable filter 5 to rise until the second connecting shaft 72 rises to the highest point. At this time, the middle part of the flexible movable filter 5 is separated from the sea surface, thereby dividing the enclosure breeding space formed in step one into two independent breeding spaces, and the fry are concentrated in the first breeding space. Then start the driving mechanism 6. Open the second breeding space, and use the first motor 65 to drive the first connecting shaft 62 to descend until the first connecting shaft 62 descends to the lowest point. At this time, the second through-hole is opened, and then the biological bait trapping lamp group 3 is started. Through the phototaxis of the bait, the bait is concentrated on the biological bait trapping lamp group 3. Then start the first motor 65 to drive the first connecting shaft 62 to rise, so that the bait is captured in the second breeding space. Then start the separation mechanism 7, and use the second motor 75 to drive the second connecting shaft 72 to descend, so that the two breeding spaces are connected, so that the bait comes into contact with the fry, and the fry are automatically provided with bait.

[0047] By using this marine ranch farming method, transitional farming is first carried out before automatic marine trapping farming to improve the adaptability of the farmed organisms. By using an aerator in the farming process, concentrated farming can prevent the farmed organisms from suffering from hypoxia, thereby further improving the adaptability of the farmed organisms in marine farming.

Step 3, trapping and breeding. After transition breeding, the fry trapping light group (2) is started, and the fry are driven to approach the first through-hole by the phototaxis of the fish. When all the fry are close to the first through-hole, the separation mechanism (7) is started, and the second motor (75) drives the second connecting shaft (72) to rise, so that the second connecting shaft (72) drives the middle part of the flexible movable filter (5) to rise until the second connecting shaft (72) rises to the highest point. At this time, the middle part of the flexible movable filter (5) is separated from the sea surface, thereby dividing the enclosure breeding space formed in step 1 into two independent breeding spaces, and the fry are concentrated in the first breeding space, and then the driving mechanism (6) is started. , open the second breeding space, drive the first connecting shaft (62) down through the first motor (65), until the first connecting shaft (62) drops to the lowest point, at which time the second through-hole is opened, and then start the biological bait trapping lamp group (3), and through the phototaxis of the bait, the bait is concentrated toward the biological bait trapping lamp group (3), and then start the first motor (65) to drive the first connecting shaft (62) up, so that the bait is captured in the second breeding space, and then start the separation mechanism (7), and drive the second connecting shaft (72) down through the second motor (75), so that the two breeding spaces are connected, and then the bait is in contact with the fry, and the fry are automatically provided with bait.
