Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine ecological protection, and provides a comprehensive device for transplanting and restoring seagrass, in particular to a comprehensive device for batch collecting, transporting and transplanting seagrass and a use method. BACKGROUND

[0002] Seagrass is the only higher plant that can live completely in seawater on earth, can effectively capture and store carbon, and has very high ecological service function. However, according to statistics, since 1990, the global seagrass bed has been decreasing at a rate of 7% per year, and about 29% of the seagrass bed has disappeared. The seagrass bed in China has also been severely damaged. Therefore, efficient seagrass transplantation is of great significance to accelerate the ecological restoration of seagrass bed and China's marine environmental protection.

[0003] 1: Restore marine ecosystems: Seagrass is a key component of marine ecosystems, providing habitat, food and breeding sites for many marine organisms. By transplanting seagrass, damaged marine ecosystems can be restored, and biodiversity can be improved.

[0004] 2: Protect the coastline: Seagrass can stabilize the seabed and reduce the erosion of the coastline by seawater. By transplanting seagrass, the stability of the coastline can be enhanced, and the safety of life and property of coastal residents can be protected.

[0005] 3: Purify water quality: Seagrass has strong ability to purify water quality, can absorb nutrients and pollutants in seawater, and reduce the risk of water eutrophication. By transplanting seagrass, water quality can be improved, and marine ecological health can be promoted.

[0006] 4: Provide carbon capture services: Seagrass is a high-efficiency carbon capturer, which can store a large amount of carbon dioxide in the ground, helping to slow down climate change. By transplanting seagrass, carbon sinks can be increased to combat global warming.

[0007] The current widely used method for restoring seagrass bed is transplantation. Specifically, the target seagrass whole plant is collected at the designated site, packed into a seagrass storage device, transported to the restoration site, and finally fixed in the restoration water area with the help of a transplantation device. However, the transplantation method also has some shortcomings, such as excessive use of spades to collect seagrass, which is too rough and can easily damage the seagrass. During the transportation of seagrass, the seagrass may die due to sudden changes in the environment, resulting in unsatisfactory restoration effect.

[0008] Therefore, there is a need for a device that can batch collect, transport and transplant seagrass. The device aims to provide a more delicate, efficient and friendly restoration solution for seagrass bed, which can greatly improve the efficiency and success rate of seagrass bed ecological restoration, and provide strong technical support for the protection and restoration of marine ecosystems.

[0042] In order to better illustrate the purpose, technical scheme and advantages of the present application, the present application will be further described below in combination with specific embodiments.

[0043] The present application provides a comprehensive device capable of batch collection, transportation and transplantation of seaweed. The comprehensive device according to the present application comprises a seaweed removal unit, a seaweed storage unit and a seaweed storage and transportation unit. Figure 3, including seaweed removal unit, seaweed storage unit, seaweed storage and transportation unit. The comprehensive device realizes efficient collection, safe transportation and rapid transplantation of seaweed by integrating different functional modules, providing a useful tool for the restoration and protection of seaweed ecosystem. The research results of the comprehensive device are helpful for the implementation of large-scale seaweed restoration project and promote the repair of damaged marine ecosystem. The seaweed removal unit is used for efficient collection of seaweed from the seabed, and the unit can be operated alone and is suitable for short-distance seaweed transplantation; the seaweed storage unit is used for temporary storage after collection to transport seaweed, and the wet and warm sensor accurately measures the environmental level in the seaweed storage unit to ensure the survival rate during transportation; the seaweed storage and transportation unit is used to transplant seaweed to the target area to ensure its survival rate.

[0044] Embodiment 1

[0045] As Figure 1 , the embodiment provides a device for short-distance collection and transplantation of seaweed, which is a seaweed removal unit, including a cylindrical handle 1, a check valve 2, a check valve 2.1 of a gas distribution nozzle cover, a cylindrical support column 3, a seaweed collection column 4 and a blade opening structure 4.1; the cylindrical handle 1 is connected with the cylindrical support column 3 perpendicularly and is internally communicated, the check valve 2 is arranged at the connecting position, the check valve 2.1 of the gas distribution nozzle cover is arranged on the cylindrical support column 3, the other regions of the cylindrical handle 1 and the cylindrical support column 3 are closed, the seaweed collection column 4 is arranged at the lower part of the cylindrical support column 3, the top of the seaweed collection column 4 is connected with the support column at the connecting position 4.2, the seaweed collection column 4 has a middle accommodating space, and the lower end of the seaweed collection column 4 is provided with the blade opening structure 4.1.

[0046] Further, the blade opening structure 4.1 is annular as a whole, which is combined by a plurality of lower separated and upper connected blade pieces 4.21, the upper parts of the blade pieces 4.21 are respectively hinged with the column body of the seaweed collection column 4 and there is a space between the adjacent blade pieces. The lower edge of the blade piece 4.21 is a blade part, which is convenient for digging downward after covering the seaweed to realize the separation of seaweed and bottom mud. The middle outer wall of each blade piece 4.21 is provided with a metal pull rope 4.22, the free end of the metal pull rope 4.22 is upward along the column body of the seaweed collection column 4, and there is a pull ring 4.23 on the free end to close the bottom of the seaweed collection column 4 after collection. The metal pull rope 4.22 does not deform during pulling.

[0047] Better, the arc length of the blade part is smaller than the upper part of the blade, forming a blade shape of wide at the top and narrow at the bottom, facilitating deep digging operation. At the same time, the sensor is fixedly arranged at the base between the adjacent blades 4.21, the water-absorbing sponge 16 covers the outside of the sensor and is connected to the middle position of the blade 4.21 on both sides of the blade 4.21, the sensor is used to receive the moisture content of the water-absorbing sponge and the pressure of the sponge, preferably, the sensor uses a temperature and humidity sensor and a pressure sensor, which can detect the temperature, humidity and other environmental conditions near the seagrass roots on one hand, since the blade 4.22 is pulled by the metal pull rope 4.22, the water-absorbing sponge 16 is squeezed, at this time the sensor can determine the stress condition of the water-absorbing sponge 16, so as to determine the relative position of each blade 4.22 and the opening degree of the whole blade part, control the closing degree of the lower part of the seagrass collecting column 4 and the water content of the water-absorbing sponge 16 during seagrass harvesting, and monitor the water retention condition of the seagrass roots, so as to ensure that the seagrass plants can survive in the seagrass collecting column 4 for a long time. If the seagrass roots are exposed during seagrass harvesting, the water-absorbing sponge 16 on the seagrass collecting column 4 will protect it, avoiding the problem of root breakage caused by the opening and closing of the blade.

[0048] Specifically, before collecting seagrass, the check valve 2 and the check valve 2.1 of the air distribution nozzle cover are in an open state, the cylindrical handle 1 is in air communication with the cylindrical support column 3, and after reaching the seagrass collection position, the check valve 2 is closed, the seagrass collecting column 4 is inserted into the bottom mud by using the blade opening structure 4.1, the insertion depth of the seagrass collecting column 4 is set to 1.5 times the root depth according to the root depth distribution of the target seagrass species, and the material characteristics of polycarbonate transparent material are used to facilitate observation during seagrass harvesting, so that the whole seagrass enters the inside of the seagrass collecting column 4. Since the seagrass is collected by digging, the roots and the bottom material are collected together, so the lower part of the seagrass collecting column 4 is still closed. At this time, the air in the cylindrical support column 3 flows outward from the check valve 2.1 of the air distribution nozzle cover in one direction, and the tube is under negative pressure. At this time, the pull ring on the seagrass collecting column 4 is pulled again, the blades are pulled in turn to close the bottom of the seagrass collecting column 4, and after the seagrass removal unit is stable, the check valve 2.1 of the air distribution nozzle cover can be closed. At this time, both check valves are in a closed state, and there is no air flow in the cylindrical support column. The dug seagrass will be in a state of being adsorbed and pulled, reducing the external damage caused by the sample weight during movement, and the friction resistance is small. The seagrass and the bottom mud are collected together in the seagrass collecting column 4.

[0049] Furthermore, polycarbonate surfaces tend to adhere strongly to sticky sediment, causing sample jamming. The inner wall of the seaweed collection column 4 is made of polytetrafluoroethylene (PTFE), or the seaweed collection column 4 is made of PTFE tube. If the target seaweed grows on a sticky substrate, such as silt or clay, the particles of this type of substrate are small (particle size < 0.063 mm) and have strong cohesion (1-5 kPa). PTFE has extremely low surface energy (approximately 18 mN / m), making it superhydrophobic. For sticky sediment (such as silt), the adhesion force can be reduced from more than 5 kPa for ordinary polycarbonate to less than 1 kPa, thereby preventing sample jamming.

[0050] After carrying the seaweed transfer unit to the target seaweed transplantation point, open the check valve 2. At this time, air enters the cylindrical support column 3 through the cylindrical handle 1, and the seaweed in the seaweed collection column 4 falls into the target point, completing the seaweed transplantation. Traditional manual digging takes about 90 seconds each time, while the single collection time of this invention is ≤30 seconds, making it suitable for narrow working windows in the intertidal zone.

[0051] Example 2

[0052] This invention provides a device for mass transplantation of seaweed, the device as follows: Figure 3 It includes seaweed storage units and seaweed transport units. The seaweed storage units are used to store separated seaweed and can be set with different heights or layers depending on the condition of the seaweed. The seaweed transport units serve as containers to store the seaweed storage units and transport the seaweed to the target location.

[0053] The seaweed storage unit includes a seaweed storage column 5, a seaweed storage column support plate 6, a fixing plate 7, a pad drag 8, a side support 9, a rope hole 10, a pad 11, and a support frame 12. The seaweed storage column 5 is located on the seaweed storage column support plate 6. The fixing plate 7 is provided at the bottom of the seaweed storage column support plate 6. Each seaweed storage column 5 has a storage space for holding seaweed. The storage space runs through the seaweed storage column support plate 6 and the fixing plate 7. The fixing plate 7 is connected to the pad 11 through the pad drag 8. The pad 11 seals the bottom of the storage space. The pad support 8 includes an L-shaped pad support 8.1 and a T-shaped pad support 8.2. The L-shaped pad support 8.1 is located on the side of the fixed plate 7, with its vertical plate connected to the fixed plate 7 and its horizontal plate receiving pads 11 through the inner groove of the L-shape. At least two pads 11 are provided. The T-shaped pads 8.2 are inverted and located in the lower center of the fixed plate 7, with their inner grooves on both sides receiving different pads 11, thereby sealing the bottom of the grass storage columns 5 at different positions. The grass storage column support plate 6 has a lifting rope hole 10 near its edge for binding the lifting rope 10.1. The pads 11 are provided with pad handles 11.1 for easy extraction and pulling.

[0054] The seaweed storage unit comprises a box 13, a side bracket 14, a box cover 15 and a water-absorbing sponge 16. The box cover 15 is used to cover the box 13, the side bracket 14 provides fixed support for the seaweed storage unit and is arranged on the inner wall of the box 13, and the water-absorbing sponge 16 is arranged at the bottom of the box 13. The water-absorbing sponge 16 is embedded with a sensor.

[0055] In the embodiment, each seaweed storage unit contains eight seaweed storage columns 5. The seaweed storage column drag plate 6 at the top and the fixing plate 7 in the middle can fix the seaweed storage column 5. There is also a removable pad 11 under every four seaweed storage columns 5 to support the seaweed in the seaweed storage column 5. The removable pad is fixed by the L-shaped pad drag under the support frame 12 and the T-shaped pad drag.

[0056] The process of using the seaweed removal unit to dig seaweed can refer to “Embodiment 1”. At this time, there is no air flow in the cylindrical support column, and the internal and external air pressures are balanced. The dug seaweed will be in an adsorbed state. Align the seaweed collection column 4 with the seaweed storage column 5, and loosen the fixed pull rope in the reverse direction to open the closed (or half-closed) blade part. The seaweed loses the bottom support force. At this time, the non-return valve 2 is opened, air enters the cylindrical support column 3 from the cylindrical handle 1, and the seaweed in the seaweed collection column 4 falls into the seaweed storage column 5. Because of the wall thickness difference between the seaweed collection column 4 and the seaweed storage column 5, the diameter of the dug seaweed block is smaller than the diameter of the seaweed storage column 5, and the seaweed block will not stick to the wall of the seaweed storage column 5. Put the collected seaweed into the seaweed storage column 5, and the seaweed roots and the associated soil are in contact with the pad 11. Place the seaweed storage unit through the side bracket 14 in the seaweed storage unit. At this time, the pad 11 is extracted, so that the bottom of the pad 11 is in contact with the pre-soaked water-absorbing sponge 16. The temperature and humidity data of the sensor control the pre-soaked water level to be consistent with the seaweed collection column 4, so as to keep the temperature and humidity of the seaweed unchanged, thereby reducing the negative impact of environmental factors caused by intermediate movement on the health status of the seaweed. Cover the box cover 15, carry the seaweed removal unit to the seaweed transplanting target point, and take it out to transplant the seaweed. The seaweed transplantation method of the present application does not require a special adaptation period.

[0057] Embodiment 3

[0058] The application provides a comprehensive device for batch collection, transportation and transplantation of seaweed, which comprises a seaweed removal unit, a seaweed storage unit and a seaweed storage and transportation unit. The seaweed removal unit can efficiently and simply collect seaweed, and the seaweed storage unit and the seaweed storage and transportation unit are used for storing seaweed and ensuring the survival rate of seaweed during transportation. The seaweed removal unit mainly comprises a cylindrical handle 1, a check valve 2, 2.1, a cylindrical support column 3 and a seaweed collection column 4. The lower part of the seaweed collection column is a blade structure 4.1. Specifically, before collecting seaweed, the check valve 2 is closed, the check valve (gas nozzle cover) 2.1 is opened, the seaweed collection column 4 is inserted into the bottom mud to collect seaweed by using the blade structure 4.1, the check valve (gas nozzle cover) 2.1 is closed after the seaweed removal unit is stable, the blade part is closed to support and use the pressure difference to take out the seaweed.

[0059] The seaweed storage and transportation unit of the application can accommodate four seaweed storage units. The box body 13 of the seaweed storage and transportation unit is made of polystyrene thermal insulation material, which can ensure the temperature inside the box body. The two sides of the seaweed storage unit are provided with side supports 9 which can be placed on the side support frames 14 inside the box body 13. The box body has a water-absorbing sponge 16 at the bottom to ensure the humidity inside the box body. After the seaweed storage unit is placed in the box body 13, the box cover 15 is closed to store and transport the collected seaweed. After arriving at the target location, the box cover 15 of the seaweed storage and transportation unit is opened, and the seaweed storage unit is taken out by using the lifting rope 10.1. At the seaweed transplantation target point, the seaweed in the seaweed storage column 5 falls into the target point by pulling out the cushion plate 11 through the cushion plate handle 11.1, and the long-distance seaweed transplantation operation is completed.

[0060] The device of the application is mainly aimed at halophila, the leaves of halophila are usually oval, oval or inversely oval, the length is 1.5-2.5 cm, the width is 1-1.4 cm, the two ends are round, and the body is small. The length of the petiole is 1.2-2.5 cm, which helps the plant to maintain balance in the water flow and effectively carry out photosynthesis. The root system of halophila is composed of one or more nodal roots, which are small and unbranched, which helps the plant to be stable in the sand soil at the bottom of the water and absorb nutrients. Halophila is mainly distributed in shallow sea, and the seaweed transplantation operation can be carried out by using the device of the application.

[0061] As Figures 4-6 After collecting seaweed, the seaweed storage and transportation unit of the application is used for the preservation treatment of becker halophila for 1h and 2h. The water-absorbing sponge in the seaweed storage and transportation unit is laid on the bottom of the box body (thickness 3-5 cm), the water-absorbing saturation of the sponge is 70-80%, the water is slowly released upward by capillary action, the temperature inside the box body is 8-12℃, and due to the high specific heat capacity of water, the sponge layer has the function of heat insulation, reducing the temperature fluctuation (±1℃) at the bottom. The temperature and humidity environment in the box body of the seaweed storage and transportation unit is monitored by the intelligent internet of things temperature and humidity sensor on the inner wall of the box body, and the data is fed back to the LED display screen on the outer wall of the box body.

[0062] The experimental group is transplanted with the device and method of the application, and an equal amount of Bacopa caroliniana not treated by the seaweed storage and transportation unit of the application but transplanted by a conventional manual method is set as a control group, and the experimental group and the control group are both soil transplanting. It can be known from analysis of experimental results that the morphological characteristics of Bacopa caroliniana in the control group change obviously, the leaf length is significantly lower than the initial state after 2h (D=2, F=3.886, P=0.033<0.05), and the leaf width also has similar changes (D=2, F=3.757, P=0.036<0.05); and the leaf length and the leaf width of Bacopa caroliniana treated by the device of the application do not change significantly after 2h. In addition, the seaweed collection column 4 is taken as a circular quadrat, the leaf cluster density of Bacopa caroliniana in the control group is significantly reduced after 2h (D=2, F=9.105, P=0.015<0.05) due to the fact that the cell sap osmotic pressure is much higher than the air humidity, leading to cell dehydration, but there is no significant difference after treatment by the device of the application.

[0063] The experimental results show that, compared with the conventional soil transplanting of the control group, the seaweed collection unit can accurately and efficiently cut seaweed from the seabed or other growth environments, ensure the integrity of the root system of the seaweed, reduce damage to the seaweed, and improve the survival rate of the seaweed; the seaweed storage unit avoids damage and death of the seaweed during transportation, and effectively ensures the freshness and vitality of the seaweed.
