Description

Technical Field

[0001] The invention relates to laver cultivation technology, and in particular to a wind and wave resistant self-drying floating raft, a deep-sea carrying-carrying type row laver cultivation device and a row self-drying method. Background Art

[0002] As offshore pollution becomes increasingly serious, the density of aquaculture increases, nutrients become increasingly scarce, and laver rot diseases become more and more common, offshore aquaculture is difficult to continue. From intertidal semi-floating laver aquaculture to pole-type laver aquaculture; from the initial pole length of 7-8 meters to the current 22-25 meters, the aquaculture area has to move to the deep sea and offshore every year. However, the length and strength of the pole are necessarily limited and can no longer meet the requirements of use in deeper waters.

[0003] At present, the methods that can be used for deep-sea culturing of laver include the flip-type dry-exposed culturing method, the tripod-type dry-exposed culturing method and the "U"-shaped tube-type dry-exposed culturing method. However, these methods have the following defects: first, the above methods all require manual operation, which is very labor-intensive and difficult to operate at sea. The drying time is controlled by humans and is difficult to grasp in time, which greatly affects the normal growth of laver; second, the wind and wave resistance is poor. The above device adopts a two-point fixing method, which is easy to deform and unstable when the wind and waves are large; third, the drying is not thorough. When drying, the height from the water surface is low, and the water foam blown by the sea breeze splashes on the net curtain, affecting the drying effect. It is impossible to completely remove algae such as green algae and diatoms, which reduces the quality of laver and reduces the yield of laver; fourth, it is impossible to carry out mechanized harvesting, and the efficiency is low. In the above laver cultivation methods, the harvesting boat cannot enter the bottom of the net curtain to harvest laver. It is blocked by the raft frame, and manual harvesting is required, which consumes a lot of labor and is inefficient. At the same time, it is difficult to control the length of laver on the net curtain after harvesting. When the seaweed is picked next time, some will be old and some will be tender, which will affect the quality of the seaweed. Fifth, when drying the seaweed manually, the seaweed on the net curtain needs to be removed from the water surface at one time, which is heavy, the operation process is complicated, the cost is high, and the seaweed yield is low. Sixth, when drying the seaweed manually, the left and right loads of the device are asymmetric and unstable. Summary of the invention

[0030] Embodiment 4, in the wind and wave resistant self-driving floating raft described in Embodiment 1: the float is made into two symmetrical halves, the float 4 has a large head end and a small head end, and a semicircular through groove 45 that closely matches the hollow lifting rod 1 is reserved at the axis of the sewing plane of each half, and two binding rope grooves 41 are horizontally arranged on the surface of the float 4, and the float 4 can be tied tightly with ropes when in use to prevent it from loosening; the two ends of the float 4 are respectively installed with a large head pressing and fixing net cover 42 and a small head fixing net cover 43 for preventing the float 4 from being washed away by waves, and a positioning clamp 44 for adjusting the position of the float 4 is connected to the net cover; a number of small balls 61 for protecting the dry root cable 6 are evenly installed on the parts of the wear-resistant pipe plugs 21 with holes at the head and tail ends of the hollow lifting rod 1 through which the dry root cable 6 passes, and the diameter of the small ball 61 is smaller than the aperture of the wear-resistant pipe plug 21, so that the dry root cable can be prevented from breaking due to friction.

[0031] Example 5, in the wind and wave resistant self-drying floating raft described in Example 1: the buoy 3 is designed and manufactured as a hollow small arc-shaped curved rod, and the two ends of the buoy 3 are sealed with rubber sealing pipe plugs 32.

A number of clamps 31 for fixing the net curtain are evenly arranged on the buoy 3; one end of the inclined rope 5 is fixed to the compression and fixing net cover 43 of the small head of the float 4, and the other end is fixed to the first clamp 31 on both sides of the middle part of the buoy 3. The two inclined ropes 5 are symmetrically arranged, which can keep the entire floating raft balanced and enhance its wind and wave resistance.

[0033] Example 7, reference Figure 5A method for self-drying a row of laver cultivation devices using the wind and wave resistant self-drying floating rafts described in Examples 1 to 5 or the deep-sea carrying-carrying-type laver cultivation devices in rows described in Example 6: the deep-sea carrying-carrying-type laver cultivation devices in rows are placed on the sea level against the rising water flow, so that the floating rod 3 on the wind and wave resistant self-drying floating valve is placed against the waves. When the tide is high, the hollow carrying rod 1 remains stable under the action of the drying root cable 6 and the inclined rope 5. Under the buoyancy of the rising tide and the impact of the waves, the float 4 on the hollow carrying rod 1 is pushed up. Since the bottom end of the hollow carrying rod 1 is pulled by the drying root cable 6 in the sea, the floating rod 4 on the hollow carrying rod 1 continues to float up when the waves continue to rush. When there is a float 4 on the hollow lifting rod 1, the float 4 rises to drive the head end of the hollow lifting rod 1 to lift up, and then the floating rod 3 fixed on the top of the hollow lifting rod 1 is lifted up, and the aquaculture net curtain 7 fixed on the floating rod 3 is further dried out of water; when the tide is low, the float 4 moves downward when the tide recedes. Because the big head of the float 4 is facing the bottom end of the hollow lifting rod 1, the bottom end of the hollow lifting rod 1 is relatively floated, and the floating rod 3 is relatively sunken. The aquaculture net curtain 7 fixed on the floating rod 3 can be completely immersed in seawater to provide nutrients for the growth of laver; when there is no tidal difference, the self-drying device and the aquaculture device can also be used for artificial drying.

[0034] The above-mentioned hollow lifting rod 1 adopts an adjustable environmentally friendly deep-sea aquaculture special support pole described in the published patent number CN201310246114.X.

[0035] By adjusting the position of the large float on the hollow lifting rod 1 or pulling the drying cable 6 to adjust the tension of the drying cable 6, the drying height and drying time of the net curtain 7 can be controlled.

[0036] When it is necessary to pick vegetables, the hollow lifting rod 1 and float 4 on the floating raft are arranged in the middle of the rows of laver cultivation devices, which will not affect the growth and picking of laver on the cultivation net curtains 7 on both sides. The cultivation net curtains 7 are suspended at the lower end of the floating rod 3 and will not affect the normal harvesting of the vegetable picking boat.
