Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine environment restoration, in particular to an ecological restoration floating raft for integrated cultivation of shellfish and seaweed and a use method thereof. BACKGROUND

[0002] In the field of water body eutrophication restoration, people have made great progress in ecological restoration by using aquatic plants, macroalgae and shellfish, and the effect of ecological restoration is also more obvious. Shellfish and seaweed integrated cultivation is a cultivation method that utilizes the different metabolic types of shellfish and seaweed to cultivate shellfish in the seaweed cultivation area. Through the absorption of inorganic nitrogen, phosphorus nutrients and pollutants by seaweed, the feeding of oysters on seaweed, the filtration of suspended particles, the absorption and degradation of pollutants, the deposition of detritus on the seabed, and the increase of carbon sink, the shellfish and seaweed integrated cultivation increases the yield, reduces pollution by absorbing nitrogen and phosphorus, diversifies products, improves production value, reduces the environmental pressure of fishery, and promotes the transformation of the industry to resource recycling and low carbon.

[0003] Currently, there are some existing technologies that can achieve ecological restoration by cultivating shellfish and seaweed on cultivation ropes, such as patent publication No. CN207973569U. The main technical means is to fix the floating raft by anchoring the four corners of the outermost floating wood, then install a protective curtain facing the direction of the rising and falling tide, and then place the seaweed seedlings and a small amount of prawns in the seaweed cultivation cage, and place the shellfish seedlings in the shellfish cultivation cage. The hanging cultivation device with the seaweed seedlings and shellfish seedlings is hung on the child floating bamboo. After analysis, the disadvantages of this technical solution are: shellfish feeding relies on the water flow to bring food resources, if the water flow in the local area is slow, the water flow exchange needs to be improved in time, and the nitrogen compounds excreted by shellfish can be absorbed and utilized by seaweed, while the dissolved oxygen released by seaweed provides a good water quality environment for shellfish. If the water flow near the floating raft is slow, it is easy to cause diffusion of metabolic products to be blocked (such as accumulation of wastewater in the shellfish aggregation area), which may break the material cycle balance, especially in windless and waveless weather, the metabolic products cannot be diffused in time. Based on this, the present application provides an ecological restoration floating raft for integrated cultivation of shellfish and seaweed and a use method thereof, which can adaptively disturb the water flow at the floating raft to ensure the effective diffusion of metabolic products.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6 As shown, this invention is an ecological restoration raft for integrated shellfish and algae aquaculture, comprising: Driftwood 1, several driftwood 1 are arranged in parallel at equal intervals, and several driftwood 1 are connected to each other by sub-driftwood 2. There are multiple sub-driftwood 2. Anchor ropes 3 are connected to the two ends of two driftwood 1 located on both sides, and anchors 4 are provided at the ends of anchor ropes 3 away from driftwood 1. Connecting plates 17 are provided at the ends of anchor ropes 3 near anchors 4, and connecting plates 17 are fixedly connected to anchors 4. The aquaculture rope 5 is provided on each of the floating logs 2, and each aquaculture rope 5 is provided with an algae aquaculture cage 6, a shellfish aquaculture cage 7 and a microbial attachment material medium 8 from top to bottom. A rotating rod 9 is rotatably mounted on the sub-float 2, and an agitator 12 is coaxially fixed to its bottom. The agitator 12 is driven to rotate by a drive source 10, which is mounted on a connecting plate 17 and connected to an electromagnetic current meter mounted on the float 1. The spoiler 13 is slidably mounted on the connecting plate 17 and is driven by the transmission assembly 15 to perform reciprocating linear motion.

[0019] In one embodiment, the microbial attachment material medium 8 is a nylon rope ball capable of adsorbing microorganisms. When unfolded, the nylon rope ball has a large adsorption surface area, enabling it to degrade organic matter in the water. The bottom of the agitator 12 is inserted into the seabed, and the agitator 12 is close to the seabed. When the agitator 12 rotates, it can drive the flow of metabolic products near the seabed, thereby increasing the diffusion rate of metabolic products and promoting material cycle balance. The drive source 10 is installed on the seabed and connected to the connecting plate 17 through a retractable structure. The retractable structure is a structure composed of nested multi-stage pipes. In practical applications, a gear and rack structure or an electric telescopic rod structure can also be used; however, this embodiment will not elaborate on this. The limitations are as follows: the output end of the drive source 10 is linked to the rotating rod 9 via the belt 11. Of course, other structures that can achieve linkage can also be used, which will not be elaborated here; the drive source 10 can be a motor assembly, or a gear assembly or pulley assembly driven by a motor, as long as it can make the agitator 12 rotate. This embodiment does not make specific limitations here; the electromagnetic flowmeter, drive source 10 and transmission assembly 15 and other electrical structures are all connected to an external controller. The above-mentioned electrical structures and external controllers are all prior art. This application has not improved them. Therefore, it is not necessary to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of this application.

[0020] In actual application, the ecological restoration floating raft is formed by connecting the plurality of floating wood 1 and the plurality of sub-floating wood 2, and then is placed in the near-shore shallow sea or the gulf which needs to be restored, and the four anchors 4 located at the four corners are fixed, and the driving source 10 and the stirring paddle 12 are installed and reinforced, then the algal seedlings and a small amount of prawns are placed in the algal cultivation cage 6, and the shellfishes are placed in the shellfish cultivation cage 7, specifically, the algal seedlings can be placed in the porphyra, and the shellfish seedlings can be placed in one of the mussels or oysters, then the water flow rate around the floating wood 1 is monitored by the electromagnetic flowmeter all the time, when the water flow rate around the floating wood 1 monitored by the electromagnetic flowmeter is reduced to the threshold value, the driving source 10 drives the rotating rod 9 to rotate, then the stirring paddle 12 rotates to accelerate the water flow, and the transmission assembly 15 drives the spoiler 13 to reciprocate linearly to disturb the water flow, so as to improve the water flow exchange, avoid the problem that the water flow rate around the floating raft is slow in the weather without wind and wave, and the diffusion of metabolic products is blocked, and the spoiler can be disturbed according to the flow rate to ensure the material circulation balance.

[0021] As shown in Figures 1-4 As a preferred embodiment of the present application, the protective curtain 18 is installed between the two anchor ropes 3 located at the same side of the floating wood 1, and the bottom of the protective curtain 18 is connected with the connecting plate 17.

[0022] In actual application, the direction of the protective curtain 18 is the direction facing the flood and ebb tide, which can effectively intercept the sea surface garbage.

[0023] As shown in Figures 1-3 As a preferred embodiment of the present application, the top end of the cultivation rope 5 is rotatably installed on the sub-floating wood 2, the rotating rod 9 is fixedly connected with the shaking block 19, and the rotating path of the shaking block 19 interferes with the position of the algal cultivation cage 6.

[0024] In actual application, considering that the adult sessile species of shellfishes (such as oysters and mussels) secrete protein to form tough byssus after adulthood through byssus gland, and are permanently attached to the substrate, which will cause the metabolic products of the shellfishes to accumulate between the shellfishes and cannot be quickly discharged, so the wastewater in the shellfish aggregation area accumulates, which is not conducive to the material circulation process, therefore, the shaking block 19 is arranged, when the rotating rod 9 is driven to rotate, the shaking block 19 rotates, and when the shaking block 19 rotates to the cultivation cage, the shaking block 19 can knock the cultivation cage to promote the metabolic products to be discharged from the cultivation cage, and when the shaking block 19 continues to rotate, the shaking block 19 pushes the algal cultivation cage 6 to rotate until the shaking block 19 rotates away from the cultivation cage, so that the shaking of the cultivation rope 5, the algal cultivation cage 6, the shellfish cultivation cage 7 and the microbial attachment material medium 8 can be realized, thereby accelerating the diffusion of the metabolic products.

[0025] As shown in Figures 1-4As shown, in a preferred embodiment of the present invention, the bottom of the shellfish culture cage 7 is provided with several wave-shaped diversion plates 16; in practical applications, the water exchange can be accelerated by diverting water.

[0026] like Figures 1-8 As shown, in a preferred embodiment of the present invention, the transmission assembly 15 includes: A frame 1501 is slidably installed inside a box 14, which is mounted on a connecting plate 17. Two limiting blocks 1506 are respectively provided at both ends of the box 14 to limit the movement path of the frame 1501. One end of the spoiler 13 is rotatably connected to one end of the frame 1501 via a rotating shaft 1503. A receiving cavity is provided inside the frame 1501. When the rotating shaft 1503 rotates, the spoiler 13 rotates to overlap with the frame 1501 and is located inside the receiving cavity. Output source 1502, its mounting end is fixed to the inner wall of housing 14, and its output end is fixedly connected to push block 1505; and The first elastic element 1504 has its two ends connected to the inner walls of the frame 1501 and the box 14, respectively. The surface of the spoiler 13 near the receiving cavity is connected to the inner wall of the frame 1501 through the second elastic element 1507. The stiffness coefficient of the first elastic element 1504 is smaller than that of the second elastic element 1507. When the second elastic element 1507 is in a free state, the spoiler 13 is perpendicular to the bottom plate of the box 14, and the position of the spoiler 13 interferes with the movement path of the pusher block 1505.

[0027] The box 14 is mounted on the seabed and connected to the connecting plate 17; the output source 1502 can be a hydraulic cylinder, a pneumatic cylinder, or other mechanisms capable of linear motion, which are not specifically limited in this embodiment; the push block 1505 is movably connected to the spoiler 13; the first elastic element 1504 and the second elastic element 1507 can both be springs, or other elastic components such as silicone pillars or spring sheets can be used instead, which are not specifically limited in this embodiment.

[0028] In one embodiment, the bottom end of the spoiler 13 is connected to the side of the receiving cavity near the output source 1502 via a rotating shaft 1503, and the pusher 1505 is located above the rotating shaft 1503. The output source 1502 is connected to an electromagnetic flow meter.

[0029] In practical applications, this embodiment, in its initial state, is as follows: Figure 5 As shown, the extension end of the output source 1502 is the shortest, that is, the distance between the push block 1505 and the output source 1502 is the shortest. At this time, the second elastic element 1507 is in a free state, the spoiler 13 is perpendicular to the bottom plate of the box 14, and the position of the spoiler 13 interferes with the movement path of the push block 1505;Figure 5 When the electromagnetic current meter detects that the water flow speed around the floating wood 1 falls to a threshold value, a signal is sent to the external controller, the external controller controls the driving source 10 to drive the rotating rod 9 to rotate, and the stirring paddle 12 rotates, and at the same time the external controller controls the output source 1502 to start, and the output end drives the push block 1505 to move away from the output source 1502, and because the stiffness coefficient of the first elastic member 1504 is smaller than that of the second elastic member 1507, the first elastic member 1504 is first stretched, that is, the frame 1501 and the spoiler 13 are synchronized to move away from the output source 1502, and the frame 1501 and the spoiler 13 always maintain a vertical state during the movement, and when the frame 1501 moves to the limiting block 1506 at the other end of the box body 14, the frame 1501 cannot move any more, and the output end of the driving source 10 drives the push block 1505 to continue to move, and the push block 1505 pushes the spoiler 13 to rotate counterclockwise, and during the process, the second elastic member 1507 is compressed, and the spoiler 13 is turned to overlap the frame 1501 and is located in the containing cavity, at this time, the spoiler 13 is located below the push block 1505, and the push block 1505 loses the pushing force, so that the elastic force of the first elastic member 1504 restores the deformation to drive the frame 1501 to move towards the output source 1502 and reset, and during the process, the spoiler 13 is located below the output end of the driving source 10 and is blocked from rotating and resetting, and is always located in the containing cavity, and when the frame 1501 is reset to contact the limiting block 1506 close to the output source 1502 in the box body 14, the output end of the driving source 10 is reset, and the spoiler 13 is reversely rotated to reset under the elastic force of the second elastic member 1507, so that the reciprocating motion of the spoiler 13 can be realized, and only in one direction can the water flow be pushed, and during the resetting process, the spoiler 13 is not in a vertical state, so as to avoid the water body from shaking, and the water flow is pushed, so that the diffusion of metabolic products is improved.

[0030] Please refer to Figures 1-8 The method is applied to the ecological restoration floating raft for integrated cultivation of shellfish and algae as described in the above embodiment, and the method comprises the following steps: Step S1: connecting a plurality of floating woods 1 and a plurality of sub-floating woods 2 to form an ecological restoration floating raft; Step S2: placing the ecological restoration floating raft in a near-shore shallow sea or a gulf in need of marine environment restoration, and fixing four anchors 4 located at four corners; Step S3: placing algae seedlings and a small amount of prawns in the algae cultivation cage 6, and placing shellfish in the shellfish cultivation cage 7; Step S4: monitoring the water flow speed around the floating wood 1 by an electromagnetic current meter; Step S5: When the electromagnetic flowmeter monitors the water flow speed around the floating wood 1 to drop to the threshold, the driving source 10 drives the rotating rod 9 to rotate, and then the stirring paddle 12 rotates to accelerate the water flow, and at the same time, the transmission assembly 15 drives the spoiler 13 to reciprocate linearly to disturb the water flow, so as to improve the water flow exchange.

[0031] The working principle of the present application: in the above embodiment of the present application, the ecological restoration floating raft for integrated cultivation of shellfish and algae and the use method thereof are provided, a plurality of floating woods 1 and a plurality of sub-floating woods 2 are connected to form an ecological restoration floating raft, the ecological restoration floating raft is placed in the nearshore shallow sea or the gulf which needs to be restored, four anchors 4 located at four corners are fixed, and at the same time, the driving source 10 and the stirring paddle 12 are reinforced and installed, then the algae seedlings and a small amount of prawns are placed in the algae cultivation cage 6, and the shellfish are placed in the shellfish cultivation cage 7, specifically, the algae seedlings can be placed in the Porphyra, and the shellfish seedlings can be placed in one of the mussels or oysters, then the electromagnetic flowmeter is always used to monitor the water flow speed around the floating wood 1, when the electromagnetic flowmeter monitors the water flow speed around the floating wood 1 to drop to the threshold, the driving source 10 drives the rotating rod 9 to rotate, and then the stirring paddle 12 rotates to accelerate the water flow, and at the same time, the transmission assembly 15 drives the spoiler 13 to reciprocate linearly to disturb the water flow, so as to improve the water flow exchange, avoid the problem that the water flow speed around the floating raft is slow in the weather without wind and waves, and cause the diffusion of metabolic products to be blocked, and the water flow can be disturbed adaptively according to the flow speed to ensure the material circulation balance.
