Description

Technical Field

[0001] The invention relates to the technical field of seaweed cultivation, in particular to a seaweed seedling raising curtain and a light supplement structure. Background Art

[0002] Seaweed seedling curtain is a sheet-like woven material specially designed for attaching and cultivating algae spores. It is a common tool in aquaculture, especially in the seedling process of large seaweeds such as kelp. The seedling curtain provides a suitable surface for algae spores to attach and grow into seedlings until they are strong enough to be transferred to a wider area of ​​water to continue growing. When cultivating seaweed through seedling curtains, the supporting lighting equipment provides the necessary light for the seaweed in the absence of light such as insufficient light or night to ensure its normal growth and development.

[0003] The Chinese patent with publication number CN203563485U discloses a seedling curtain, a fixing structure and a cultivation structure suitable for the cultivation of Sargassum in northern seas. The seedling curtain of the utility model of the patent, combined with the supporting improved nursery pond and the offshore management method, can effectively reduce the labor intensity. At the same time, the vertical cultivation method is adopted according to the characteristics of the sea conditions in the northern seas. Compared with the traditional flat cultivation method, it effectively reduces the attachment of sea mud, miscellaneous algae and invertebrates, is conducive to the growth of seaweed, and reduces the cost of human resources; The Chinese patent with publication number CN107549003B discloses a vertical kelp seedling device and a method of using the same. The invention aims at the problems existing in kelp seedling cultivation and develops a vertical seedling cultivation mode that can automatically adjust the light source, which solves the problems of uneven illumination and insufficient bottom illumination in the traditional three-dimensional cultivation method. While saving the floor space of the seedling room and saving energy, the seedling cultivation efficiency is improved. The invention can also promote the exchange of water flow and air flow in the seedling cultivation pool, avoiding the drawbacks of oxygen accumulation and insufficient carbon dioxide produced in the flat cultivation method. The seedling curtains of the above two technical solutions are hung in the seedling pool when in use, and the overall structure of the seedling curtain is an integrated design. The bubbles and attachments generated during seaweed cultivation will continue to attach to the seedling curtain. In order to ensure the continuous photosynthesis of seaweed on the seedling curtain, the staff is generally required to pull up the seedling curtain and shake it to remove the bubbles and other algae attachments, and when there is insufficient light in seaweed cultivation, the seedling curtain needs to be turned upside down to balance the photosynthesis of the upper and lower sides of the seedling curtain. These operations require manual processing of the seedling curtains one by one, and when the light is insufficient, efficient light supplement can no longer be achieved by turning the seedling curtain upside down. Therefore, we proposed a seaweed seedling curtain and a light supplement structure. Summary of the invention

[0016] 1. The seaweed seedling curtain and light-filling structure realizes the reciprocating movement of extension and contraction by driving the lateral expansion mechanism through the trigger mechanism, so that the cloth strips between the iron bars and the clamping plates can realize the reciprocating adjustment of contraction and tension and extension, and the gaps between the multiple cloth strips are adjusted, so that when the water flows through the gaps between the multiple cloth strips, the bubbles generated by the seaweed can be taken away, which is beneficial to the exchange of gas and avoids the accumulation of bubbles that affect the water quality and photosynthesis.

The seaweed seedling curtain and light-filling structure, when the driving mechanism is started, the chain drives the seedling curtain body to move under the hanging frame through the connecting piece. When the seedling curtain body moves under the long hanging beam part on one side of the hanging frame, the seedling curtain body will move against the direction of the water flow, so that the seedling curtain body can be washed by the water flow faster when the seaweed is hung for cultivation; 3.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 13 The present invention provides a technical solution: a seaweed seedling curtain, comprising a seedling curtain main body 1, the seedling curtain main body 1 comprises two parallel iron bars 101, an equidistantly distributed clamping plate 102 is arranged between the two iron bars 101, a cloth strip 103 is fixed between the iron bars 101 and the clamping plate 102, an X-shaped bracket 104 is arranged on one side of the cloth strip 103, the four corners of the X-shaped bracket 104 are respectively fixed to the ends of the two iron bars 101, the guide frame 201 is parallel to the iron bars 101, the X-shaped bracket 104 can support and reinforce the two iron bars 101, and a lateral expansion mechanism 2 is arranged between the clamping plate 102 and the X-shaped bracket 104; The lateral expansion mechanism 2 includes a guide frame 201 fixed to the X-shaped bracket 104, a sliding rod 202 is fixed between the end of the guide frame 201 and the X-shaped bracket 104, a rotating shaft 203 is connected to the middle of the X-shaped bracket 104, and the rotating shaft 203 is movably connected to the middle of the scissor arm 204. The scissor arm 204 is composed of crossed straight plates and hinged shafts, and the crossed straight plates are rotationally connected through the middle hinged shaft, and the ends of two adjacent straight plates are rotationally connected through the lateral hinged shaft. The end of the middle hinged shaft of the scissor arm 204 is fixed with a limiting column 205 installed with the clamping plate 102, and the end of the lateral hinged shaft of the scissor arm 204 is fixed with a connecting column 206, and an elastic retaining ring 207 is fixed on the end of the connecting column 206 away from the scissor arm 204. When the scissor arm 204 is extended and telescoped, the upper and lower lateral hinged shafts of the scissor arm 204 will drive the connecting column 206 to move closer to each other. , so that the two adjacent connecting columns 206 will squeeze the elastic retaining ring 207 from the longitudinal ellipse to the transverse ellipse, so that the change of the elastic retaining ring 207 can adapt to the spacing adjustment of the two adjacent clamping plates 102, and then the clamping plate 102 can be restricted by the elastic retaining ring 207 to prevent the clamping plate 102 and the cloth strip 103 from moving away from the X-shaped bracket 104 and causing the loose deformation of the overall structure of the seedling curtain body 1. The lateral hinge shafts on both sides of the scissor arm 204 close to the rotating shaft 203 are connected with push-pull arms 208, and a movable block 209 is hinged between the two adjacent push-pull arms 208. A clamping seat 210 is fixed on the middle hinge shaft of the scissor arm 204 close to the end of the guide frame 201. The clamping seat 210 is slidably connected to the slide bar 202, and the end opening of the clamping seat 210 is smaller than the diameter of the slide bar 202, which is convenient for the clamping seat 210 and the slide bar 202 to be quickly installed and disassembled by snapping; The middle surface of the X-shaped bracket 104 is provided with a slide groove 1041 for the push-pull arm 208 to slide through. The slide groove 1041 is an arc-shaped structure, and the slide groove 1041 is symmetrically distributed about the center line of the X-shaped bracket 104, and the axis of the slide groove 1041 coincides with the axis of the rotating shaft 203; when the scissor arm 204 rotates through the middle hinge shaft, the scissor arm 204 will extend and retract to both sides with the rotating shaft 203 as the center, so that the scissor arm 204 drives the two push-pull arms 208 to rotate around the rotating shaft 203, so that the push-pull arm 208 can be slidably guided through the slide groove 1041 with an arc structure; The guide frame 201 is provided with equidistantly distributed protrusions 2011 on both side edges close to the cloth strip 103, the protrusions 2011 abut against the cloth strip 103, and the upper and lower ends of the clamping plate 102 slide and fit with the guide frame 201. When the scissor arms 204 extend and retract to both sides with the rotating shaft 203 as the center, multiple cloth strips 103 can be driven to abut against the protrusions 2011 on the edge of the guide frame 201 to adjust the spacing. The cloth strip 103 can generate vibration when moving along the equidistantly distributed protrusions 2011, so as to fully remove the bubbles generated by seaweed on the cloth strip 103.

[0021] During the specific implementation, the two push-pull arms 208 are driven to slide and adjust in the slide groove 1041 on the surface of the X-shaped bracket 104 by pressing down the movable block 209, so that the bottom ends of the two push-pull arms 208 are away from each other, and the two push-pull arms 208 will push the two lateral hinge shafts of the scissor fork arm 204 away from each other, thereby driving the scissor fork arm 204 to extend and retract to both sides with the rotating shaft 203 as the center, so that the clamping seats 210 at both ends of the scissor fork arm 204 are slidably guided along the slide rod 202, thereby ensuring that the two sides of the seedling curtain body 1 are tightly attached to the guide frame 201, so that the outermost cloth strips 103 of the seedling curtain body 1 will not be loose; When the scissor arms 204 are extended and telescoped, the limiting posts 205 on the middle hinge shaft will be driven to move away from each other to increase the distance between the two adjacent limiting posts 205, so that the limiting posts 205 can drive the two adjacent clamping plates 102 to move away from each other to increase the gap. At this time, the distance between the multiple cloth strips 103 on the iron bar 101 remains unchanged, so that the gap between the multiple cloth strips 103 is adjusted. At this time, the cloth strips 103 located between the iron bar 101 and the clamping plate 102 can be straightened and tightened when the two adjacent clamping plates 102 move away from each other. Therefore, when water flows through the gaps between the multiple cloth strips 103, it can take away the bubbles generated by the seaweed, and can accelerate the water flow between the multiple cloth strips 103, which is beneficial to gas exchange, so that the water quality in the area where the seaweed cultivation seedling curtain main body 1 is placed can be improved regularly to avoid the accumulation of bubbles that affect the water quality and photosynthesis; by regularly tightening and straightening the cloth strips 103, the sludge and harmful organisms on the seedling curtain main body 1 can be effectively removed when the water flows through the gaps between the adjacent cloth strips 103, and impurities can be quickly removed when the seedling curtain main body 1 is removed for flushing.

[0022] See also Figure 4-Figure 11 A trigger mechanism 3 is arranged on the side of the iron bar 101 at the top of the main body 1 of the seedling curtain. The trigger mechanism 3 includes a cross bar 301 welded to the surface of the iron bar 101 at the top of the main body 1 of the seedling curtain. A strip-shaped cavity is opened in the middle of the cross bar 301. A push plate 302 is hinged on the upper side of the cross bar 301. A reset spring 303 is fixed between the cross bar 301 and the push plate 302. When the push plate 302 is not subjected to external compression, the straightened cloth strip 103 can pull multiple splints 102 to move closer to each other and reset when shrinking and resetting, and the push of the reset spring 303 can accelerate the contraction and reset of the lateral expansion mechanism 2; The lower side of the push plate 302 is movably connected with a pressure rod 304 penetrating the strip cavity. A spherical groove is provided on the top of the movable block 209. The bottom end of the pressure rod 304 is movably connected with the spherical groove on the top of the movable block 209 through the spherical block.

[0023] During specific implementation, by squeezing the push plate 302 of the trigger mechanism 3, the push plate 302 is made to rotate around one side of the cross bar 301, so that the return spring 303 between the push plate 302 and the cross bar 301 is compressed and deformed, and at the same time, the rotation of the push plate 302 can push the pressure rod 304 to slide and retract in the middle of the cross bar 301, thereby driving the pressure rod 304 to squeeze the movable block 209 downward, so that the scissor arms 204 of the lateral expansion mechanism 2 are extended and retracted to both sides. By setting up the trigger mechanism 3, the lateral expansion mechanism 2 can be driven to realize the reciprocating motion of extension and contraction, and then the cloth strip 103 between the iron bar 101 and the splint 102 can be driven by the lateral expansion mechanism 2 to realize the reciprocating adjustment of contraction and tension extension.

[0024] See also Figure 1 and Figure 2 A fill-in light structure comprises a hanging frame 4 and a fill-in light 8. The hanging frame 4 is suspended and installed on the top of the beam of an indoor nursery pool through a suspension rod 9. A support frame 7 is fixed above the hanging frame 4. A fill-in light 8 is installed on the lower surface of the top of the support frame 7. By connecting the fill-in light 8 on the lower surface of the top of the support frame 7 to a power source, the fill-in light 8 can be powered on, so that the seedling curtain main body 1 in the nursery pool can be filled with light, thereby providing sufficient light for the seaweed on the seedling curtain main body 1.

[0025] See also Figure 1-Figure 7 A driving mechanism 5 is provided at the lower side of the suspension frame 4, and the driving mechanism 5 includes a guide rail 501 fixed on the lower surface of the suspension frame 4. The suspension frame 4 is composed of a long hanging beam portion, a short hanging beam portion, and a rounded portion between the long hanging beam portion and the short hanging beam portion. A motor seat 505 is installed above the rounded portion of the suspension frame 4, and a sprocket 506 is fixed to the bottom output end of the motor seat 505; The guide rail 501 is internally connected to a hanging wheel 502 in a rolling manner, and the bottom end of the hanging wheel 502 is connected to a chain 503. The bottom end of the chain 503 is movably connected to the iron bar 101 on the top of the seedling curtain body 1 through a connector 504. The connector 504 consists of a pull rod sleeve and a central axis. The top of the pull rod sleeve of the connector 504 is fixed to the chain 503, and the bottom of the pull rod sleeve is sleeved with the central axis. The central axis of the connector 504 is fixed to the iron bar 101 on the top of the seedling curtain body 1; the pull rod sleeve of the connector 504 is sleeved with the central axis, so that the iron bar 101 on the top of the seedling curtain body 1 can rotate around the pull rod sleeve through the central axis.

[0026] During the specific implementation, the long hanging beam of the hanging frame 4 is arranged along the water flow direction of the seedling pool. Usually, multiple groups of seedling curtain bodies 1 are hung below the long hanging beam of the hanging frame 4, thereby saving space in the seedling pool and reducing the floor area of ​​the seedling pool. By starting the motor seat 505 on the rounded part of the suspension frame 4, the sprocket 506 is driven to rotate, so that the sprocket 506 can drive the chain 503 to rotate. Since the hanging wheel 502 on the top of the chain 503 is hung in the guide rail 501, the chain 503 can drive the hanging wheel 502 to move smoothly in the guide rail 501 during operation, thereby ensuring that the chain 503 will not fall off when suspended under the guide rail 501. At the same time, when the chain 503 is hung on the seedling curtain body 1 through the connecting piece 504 at the bottom, the connection between the hanging wheel 502 and the guide rail 501 can ensure that the chain 503 can stably pull the seedling curtain body 1 to circulate along the trajectory of the suspension frame 4 in the seedling pool.

[0027] See also Figure 1 and Figure 2 The guide mechanism 6 includes a floating plate 601 fixed to the hanging frame 4. The floating plate 601 is made of wood or plastic material with a density less than that of water. The surface of the floating plate 601 is longitudinally slidably connected with a U-shaped tube 602. The U-shaped tube 602 is movably connected with an adjusting screw 603. The adjusting screw 603 is threadedly connected to the floating plate 601. By rotating the adjusting screw 603 on the floating plate 601, the adjusting screw 603 and the floating plate 601 can be driven to transmit threadedly, so that the adjusting screw 603 can drive the U-shaped tube 602 to slide longitudinally on the floating plate 601, so as to facilitate the adjustment of the position of the bottom of the U-shaped tube 602. Then, the U-shaped tube 602 is squeezed with the push plate 302 at different heights, so that the cross bar 301 and the push plate 302 can drive the seedling curtain body 1 to rotate around the connecting piece 504 to different inclinations, so as to adjust the floating height of the seedling curtain body 1 according to the demand for seaweed supplementary lighting.

[0028] In specific implementation, when the driving mechanism 5 is started, the chain 503 drives the seedling curtain body 1 to move under the long hanging beam part, the short hanging beam part and the rounded part of the hanging frame 4 through the connecting piece 504. When the seedling curtain body 1 moves under the long hanging beam part on one side of the hanging frame 4, the seedling curtain body 1 will move against the direction of the water flow. At this time, the seaweed attached to the seedling curtain body 1 will be washed by the water flow, and bubbles and debris can be quickly removed. When the seedling curtain body 1 moves under the long hanging beam part on the other side of the hanging frame 4, the seedling curtain body 1 will move along the water flow direction. At this time, the movement of the seedling curtain body 1 can drive the attached seaweed to move smoothly. When the main body 1 of the seedling curtain moves from the bottom of the rounded part to the bottom of the short hanging beam part, the trigger mechanism 3 on the top of the main body 1 of the seedling curtain will gradually approach the guide mechanism 6. When the push plate 302 is squeezed with the bottom of the U-shaped tube 602, the lateral expansion mechanism 2 can be driven to drive the main body 1 of the seedling curtain to achieve lateral tightening and extension, thereby increasing the gap between adjacent cloth strips 103. When the water flows radially through the gap between the cloth strips 103, it can take away bubbles and attachments. When the cross bar 301, the push plate 302 and the bottom of the U-shaped tube 602 are squeezed and slid, the iron bar 101 on the top of the main body 1 of the seedling curtain will go around the connecting piece 5. 04 rotates, thereby adjusting the seedling curtain body 1 from a state of hanging in the water to a tilted state. Since the guide mechanism 6 is located on the outside of the hanging frame 4, the seedling curtain body 1 will deflect and float toward the center of the hanging frame 4, and then the seedling curtain body 1 will drive the attached seaweed closer to the water surface, ensuring that the fill light 8 on the support frame 7 can fully fill in the light for the floating seedling curtain body 1. When the seedling curtain body 1 is driven by the driving mechanism 5 to move in a circle along the trajectory of the hanging frame 4, all the seedling curtain bodies 1 can be driven to float and fill in light at the positions of the two short hanging beams.

[0029] To sum up, the seedling curtain main body 1 is hung and installed on the chain 503 at the bottom of the hanging frame 4. When the driving mechanism 5 is started, the seedling curtain main body 1 can be driven to move along the trajectory of the hanging frame 4. When the seedling curtain main body 1 moves to the bottom of the long hanging beam of the hanging frame 4, the seedling curtain main body 1 is hung and placed, thereby reducing the occupied area of ​​the seedling curtain main body 1 in the seedling pool and avoiding direct light. When the seedling curtain main body 1 moves to the bottom of the short hanging beam of the hanging frame 4, the seedling curtain main body 1 is tilted and floated, and then the fill light 8 is powered on, so that the hanging and tilted seedling curtain main bodies 1 in the seedling pool can be fully supplemented with light, thereby ensuring that seaweed can grow rapidly during cultivation.
