Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a semi-submersible aquaculture platform with an FRP-reinforced UHPC structure. Background Art

[0002] A semi-submersible aquaculture platform with FRP-reinforced UHPC structure is a new type of marine aquaculture facility. FRP (fiber reinforced composite material) has the advantages of high strength and corrosion resistance, while UHPC (ultra-high performance concrete) has high strength, high durability and good working performance. Combining FRP and UHPC in semi-submersible aquaculture platforms can improve the structural performance and durability of the platform and adapt to the complex conditions of the marine environment.

[0003] Semi-submersible aquaculture platforms are located in the sea, and the seawater is rich in various nutrients, which provides suitable conditions for the growth and reproduction of marine organisms. Under the action of water flow, the larvae or spores of marine organisms are more likely to contact the surface of the platform and attach and grow on it, such as green algae and brown algae. The secretions and metabolites of marine organisms contain acidic substances, which corrode the FRP reinforced UHPC structure. In addition, biological attachments will increase the weight of the platform, resulting in an increase in structural load, which may affect the stability and safety of the platform. In the prior art, professional divers are arranged to carry scrubbing tools and dive into the water to manually scrub the underwater part of the aquaculture platform. Scrubbing, but diving operations themselves are dangerous, and the underwater environment is complex. Factors such as water flow and water pressure can pose a threat to the life safety of divers. In addition, manual diving scrubbing is slow and requires divers to clean area by area, which takes a lot of time and manpower. It is difficult to complete large-scale scrubbing in a short time. Divers will use some cleaning agents or tools during the scrubbing process. If these substances enter the water body, they will cause certain pollution to the water quality, and then affect the living environment of farmed organisms. Divers need to consume a lot of physical strength to scrub underwater. Long-term work will cause diver fatigue, affecting work quality and efficiency.

[0004] In addition, floating objects also appear on the sea surface, such as garbage discharge, waste from fishing activities (such as fishing nets, fishing gear fragments), domestic garbage and industrial waste in coastal areas, etc., which will enter the ocean through rivers, rainwater or direct dumping to form floating objects. Ships at sea will generate garbage during navigation, such as discarded packaging materials, ropes, plastics, etc. If these garbage are not properly handled, they will enter the ocean and float on the sea surface, and the organic matter and pollutants in the floating objects will be released into the water, causing water quality to deteriorate, affecting the living environment and health of farmed fish. A large amount of floating objects will block the water flow, affect the water exchange around the breeding platform, and reduce Low self-purification capacity of water bodies increases the risk of water quality deterioration. Floating objects will be entangled in cages, pipes and other facilities of aquaculture platforms, affecting the normal operation of the facilities and even causing damage to the facilities. Floating objects will carry pathogens and parasites, increasing the risk of farmed fish contracting diseases. Floating objects such as plastic bags, fishing nets, and waste will impact the surface of the FRP-reinforced UHPC structure under the action of ocean currents, causing physical damage. These damages may include scratches and cracks, which can lead to a decrease in structural strength in severe cases. Floating objects contain chemical substances, such as chemicals decomposed from certain plastics, which can cause corrosion to the FRP-reinforced UHPC structure.

[0005] Therefore, a semi-submersible aquaculture platform with FRP reinforced UHPC structure is proposed to solve the above problems. Summary of the invention

[0016] Preferably, a detector is fixedly connected to the bottom surface of the base.

[0017] Preferably, the sliding rod is slidably connected to the first cylinder.

[0018] Compared with the prior art, the present invention provides a semi-submersible aquaculture platform with an FRP-reinforced UHPC structure, which has the following beneficial effects:

[0019] 1. Through the cooperation between the telescopic rod, the first auxiliary plate, the connecting plate, the coating roller, the rotating disk, the rectangular trough, the sliding rod, the first cylinder, the connecting pipe and the cleaning roller in the auxiliary breeding mechanism, the surface of the breeding platform body can be automatically scrubbed and coated with antifouling agent. The antifouling agent can form a protective film on the surface of the trough body to prevent the attachment of dirt, algae and other microorganisms for a long time, and prolong the duration of the cleaning effect. Since FRP has the advantages of high strength and corrosion resistance, and UHPC has high strength, high durability and good working performance, the combination of FRP and UHPC in the semi-submersible breeding platform can improve the structural performance and durability of the platform, and the surface is coated with antifouling agent. The antifouling agent can not only prevent biological attachment, but also prevent the damage of UHPC materials to environmental factors such as ultraviolet rays and salt spray to a certain extent, thereby delaying the aging process of the structure. The coating of antifouling agent can reduce the direct contact of seawater with the UHPC material. Direct erosion, reduce the dissolution and carbonization of cementitious materials in UHPC materials, protect the integrity of FRP layer and UHPC layer. Due to the effect of antifouling agent, the surface of the tank is not easy to be contaminated, which can significantly reduce the frequency of manual cleaning and save manpower and time costs. When cleaning is required, the surface treated with antifouling agent is easier to clean, and dirt is not easy to adhere firmly, which can improve cleaning efficiency. Antifouling agent can protect the tank material, reduce corrosion and wear, extend the service life of equipment, prevent microorganisms from multiplying in large numbers on the surface of the tank, help maintain good water quality, and create a healthier environment for farmed organisms. Since cleaning becomes easier, the reduction in cleaning and maintenance time means that the breeding facilities can have more time for production, improve overall efficiency, reduce the need for frequent scrubbing, reduce the labor intensity of workers, improve working conditions, reduce the interference and stress response caused by frequent cleaning to farmed organisms, and are beneficial to the growth and health of organisms.

[0020] 2. The debris generated by scrubbing can be collected through the cooperation between the storage box, auxiliary cylinder, telescopic plate and rotating block in the auxiliary breeding mechanism. The rotating block can more effectively guide the debris to the collection tank, reduce the residue of debris in the tank body, and improve the overall cleaning effect. Directly introducing the debris into the collection tank can prevent the debris from being dispersed again in the water, reducing the risk of secondary pollution. Centralized collection of debris makes subsequent processing more convenient, and waste classification and processing can be easier. Rapid removal of debris helps maintain water quality and create a healthier living environment for cultured organisms. Timely removal of debris can reduce wear on the tank body and other equipment and extend service life.

[0021] 3. The floating objects on the sea surface can be collected by the cooperation among the second rotating column, the disc, the auxiliary block, the second cylinder, the reset spring, the bottom plate and the collecting cylinder in the auxiliary maintenance mechanism. Removing the floating objects can reduce the deterioration of water quality caused by the decomposition of organic matter and maintain a good breeding environment. Reducing the floating objects can reduce the risk of accidental ingestion or entanglement of the breeding organisms and protect their health. Removing the floating objects can increase the degree of sunlight penetrating the water surface, which is beneficial to the growth of plankton in the water body and improves the water body ecosystem. Removing the floating objects can prevent the floating objects from clogging the water inlet, filtration system and other equipment to ensure the normal operation of the breeding system. The clean water surface is conducive to the staff to observe and monitor the breeding situation. The floating objects will carry pathogens. Removing them can reduce the risk of disease transmission. Good environmental conditions help to improve breeding. The growth rate and survival rate of organisms, clean water surface improves the working environment and will increase the work enthusiasm of employees. Timely removal of organic floating objects can reduce the stench caused by decay. Timely cleaning of floating objects can prevent pollutants from further spreading to the surrounding sea areas. Floating objects such as plastic bags, fishing nets, waste, etc. will impact the surface of the FRP-reinforced UHPC structure under the action of ocean currents, causing physical damage. These damages may include scratches and cracks, which may cause a decrease in structural strength in severe cases. Collecting floating objects can reduce these physical damages and extend the service life of the structure. Floating objects contain chemical substances, such as certain chemicals decomposed from plastics. These substances will cause corrosion to the FRP-reinforced UHPC structure. By collecting floating objects, the contact between these corrosive substances and the structure can be reduced, protecting the structure from chemical erosion. BRIEF DESCRIPTION OF THE DRAWINGS

Sliding rods 307 are fixedly connected to both sides of the rectangular trough body 306. A connecting pipe 309 is fixedly connected to the arc surface of one end of the first cylinder 308 away from the rotating disk 305.

[0044] A cleaning roller 310 is rotatably connected to the bottom end of the inner wall of the connecting plate 303, a storage box 311 is fixedly connected to the bottom surface of the connecting plate 303, a telescopic plate 313 is fixedly connected to the top surface of the inner wall of the storage box 311, an auxiliary cylinder 312 is fixedly connected to the side of the storage box 311, a rotating block 314 is rotatably connected to the inside of the auxiliary cylinder 312, a reciprocating screw rod 315 is rotatably connected to the bottom surface of the inner wall of the breeding platform body 2, and a brush plate 316 is slidably connected to the outer surface of the reciprocating screw rod 315.

The antifouling agent will not pollute the ocean. The coating roller 304 is connected to the connecting pipe 309, and the coating roller 304 is in contact with the surface of the aquaculture platform body 2. Due to the effect of friction, the coating roller 304 will be driven to rotate, and the antifouling agent can be applied to the outer surface of the aquaculture platform body 2.

[0047] In the prior art, professional divers are arranged to carry scrubbing tools and dive into the water to manually scrub the underwater part of the aquaculture platform. However, the diving operation itself is dangerous, and the underwater environment is complex. Factors such as water flow and water pressure may threaten the life safety of divers. In addition, manual diving scrubbing is slow, and divers are required to clean each area one by one, which takes a lot of time and manpower. It is difficult to complete the scrubbing of a large area in a short time. Divers will use some cleaning agents or tools during the scrubbing process. If these substances enter the water body, they will cause certain pollution to the water quality, thereby affecting the living environment of the aquaculture organisms. Divers need to spend a lot of time and effort to perform underwater scrubbing. Physical strength, long-term work will cause diver fatigue, affecting work quality and efficiency.

The antifouling agent can form a protective film on the surface of the tank to prevent the attachment of dirt, algae and other microorganisms for a long time, and prolong the duration of the cleaning effect. Because FRP has the advantages of high strength and corrosion resistance, while UHPC With high strength, high durability and good working performance, the combination of FRP and UHPC for semi-submersible aquaculture platforms can improve the structural performance and durability of the platform, and the antifouling agent is coated on its surface. The antifouling agent can not only prevent biological attachment, but also prevent the damage of environmental factors such as ultraviolet rays and salt spray to UHPC materials to a certain extent, thereby delaying the aging process of the structure. The coating of the antifouling agent can reduce the direct erosion of seawater, reduce the dissolution and carbonization of the cementitious materials in the UHPC material, and protect the integrity of the FRP layer and the UHPC layer. Due to the effect of the antifouling agent, the surface of the tank is not easy to be contaminated, which can significantly reduce the frequency of manual cleaning, saving manpower and time. Time cost, when cleaning is needed, the surface treated with antifouling agent is easier to clean, dirt is not easy to adhere firmly, which can improve cleaning efficiency, antifouling agent can protect the tank material, reduce corrosion and wear, extend the service life of equipment, prevent microorganisms from multiplying in large numbers on the surface of the tank, help maintain good water quality, and create a healthier environment for farmed organisms. Since cleaning becomes easier, the reduction in cleaning and maintenance time means that the breeding facilities can have more time for production, improve overall efficiency, reduce the need for frequent scrubbing, reduce the labor intensity of workers, improve working conditions, reduce the interference and stress response caused by frequent cleaning to farmed organisms, and are beneficial to the growth and health of organisms.

[0048] For further examples, please refer to Figures 8 to 10 As shown:

[0052] The end of the second rotating column 410 close to the outer frame 409 is fixedly connected to the disk 411, and the second rotating column 410 is located at the eccentric part of the disk 411. The eccentric part of the disk 411 is rotatably connected to an auxiliary block 412, and the position of the auxiliary block 412 and the second rotating column 410 are diagonally related.

When the ratchet 419 rotates clockwise, it cannot drive the pawl 420 to rotate. On the contrary, the ratchet 419 can drive the pawl 420 to rotate by rotating counterclockwise. A belt is connected between the third cylinder 418 and the bottom plate 416.

[0055] In the existing technology, organic matter and pollutants in floating objects will be released into the water, causing water quality to deteriorate, affecting the living environment and health of farmed fish. A large amount of floating objects will block the water flow, affect the water exchange around the breeding platform, reduce the self-purification capacity of the water body, and increase the risk of water quality deterioration. Floating objects will be entangled in the cages, pipes and other facilities of the breeding platform, affecting the normal operation of the facilities and even causing damage to the facilities. Floating objects will carry pathogens and parasites, increasing the risk of farmed fish infection. Floating objects such as plastic bags, fishing nets, and waste will hit the surface of the FRP-reinforced UHPC structure under the action of the ocean current, causing physical damage. This Some damage may include scratches and cracks, which may lead to a decrease in structural strength in severe cases. Floating objects contain chemical substances, such as chemical substances decomposed from certain plastics, which may cause corrosion to the FRP reinforced UHPC structure. Compared with the prior art, the floating objects on the sea surface can be collected by the cooperation among the second rotating column 410, the disc 411, the auxiliary block 412, the second cylinder 413, the return spring 414, the bottom plate 416 and the collecting cylinder 417 in the auxiliary maintenance mechanism. Removing floating objects can reduce the deterioration of water quality caused by the decomposition of organic matter and maintain a good aquaculture environment. Reducing floating objects can reduce the risk of accidental ingestion or being eaten by aquaculture organisms. The risk of entanglement can be reduced, and their health can be protected. Removing floating objects can increase the degree of sunlight penetrating the water surface, which is beneficial to the growth of plankton in the water body and improves the aquatic ecosystem. Removing floating objects can prevent floating objects from clogging water inlets, filtration systems and other equipment, ensuring the normal operation of the aquaculture system. Clean water surfaces are conducive to staff observation and monitoring of aquaculture conditions. Floating objects carry pathogens, and removing them can reduce the risk of disease transmission. Good environmental conditions help to improve the growth rate and survival rate of aquaculture organisms. Clean water surfaces improve the working environment and increase the work enthusiasm of employees. Timely removal of organic floating objects can reduce the odor caused by decay. Timely cleaning of floating objects can prevent pollutants from further spreading to the surrounding sea areas. Floating objects such as plastic bags, fishing nets, and waste will impact the surface of the FRP-reinforced UHPC structure under the action of ocean currents, causing physical damage.

Collecting floating objects can reduce these physical damages and extend the service life of the structure.

[0056] Everything in the above example works like this:

[0057] In the initial state: the first cylinder 308 is filled with antifouling agent.

[0058] The following is the working process of the auxiliary breeding mechanism scraping off the debris on the surface of the breeding platform body 2:

[0059] When in use, the cleaning roller 310 rotates to scrub the surface of the breeding platform body 2, and at the same time, the rotating block 314 and the reciprocating screw 315 are also rotating. The rotation of the rotating block 314 will drive the surrounding water to flow, forming a certain water flow or vortex. This water flow can generate suction to entrain and suck away impurities, dirt or other substances generated by scrubbing. That is, the rotation of the rotating block 314 can suck the debris generated by the cleaning roller 310 when scrubbing into the interior of the storage box 311 for collection, and the reciprocating screw 315 rotates to drive the brush plate threadedly connected to it. 316 reciprocates on the inner bottom surface of the aquaculture platform body 2, and then scrubs the inner wall bottom surface of the aquaculture platform body 2, reducing the residue of debris in the tank body, improving the overall cleaning effect, and directly introducing the debris into the collection tank, which can prevent the debris from being dispersed again in the water, reducing the risk of secondary pollution, and centrally collecting the debris makes subsequent processing more convenient, making it easier to classify and process waste, and quickly removing the debris helps maintain water quality and create a healthier living environment for aquaculture organisms. Timely removal of debris can reduce wear of the tank body and other equipment and extend the service life;

[0060] Since seawater is rich in various nutrients, it provides suitable conditions for the growth and reproduction of marine organisms. Under the action of water flow, the larvae or spores of marine organisms can more easily contact the surface of the platform and attach and grow on it, such as green algae and brown algae. When the detector 317 detects that green algae, brown algae and other debris are attached to the surface of the breeding platform body 2, the detector 317 is electrically connected to the driving device, and the driving device can drive the telescopic rod 301 to extend and retract, and at the same time drive the rotating disk 305, the cleaning roller 310, the rotating block 314 and the reciprocating screw 315 to rotate together. The extension and retraction of the telescopic rod 301 can drive the first auxiliary plate 302 fixedly connected thereto to move up and down on the outer surface of the breeding platform body 2, and then drive the connecting plate 303 fixedly connected thereto to move up and down together. The connecting plate 303 moves up and down, driving the coating roller 304 connected to it to move up and down on the surface of the aquaculture platform body 2. Since the coating roller 304 fits the surface of the aquaculture platform body 2, the friction force will drive the coating roller 304 to rotate, thereby, the antifouling agent can be applied to the outer surface of the aquaculture platform body 2. The antifouling agent can form a protective film on the surface of the tank body, which can prevent the attachment of dirt, algae and other microorganisms for a long time and prolong the duration of the cleaning effect. Since FRP has the advantages of high strength and corrosion resistance, and UHPC has high strength, high durability and good working performance, the combination of FRP and UHPC in the semi-submersible aquaculture platform can improve the structural performance and durability of the platform, and the surface is coated with antifouling Antifouling agents can not only prevent biological attachment, but also prevent the damage of UHPC materials to some extent by environmental factors such as ultraviolet rays and salt spray, thereby delaying the aging process of the structure. The coating of antifouling agents can reduce the direct erosion of seawater, reduce the dissolution and carbonization of cementitious materials in UHPC materials, and protect the integrity of FRP layers and UHPC layers. Due to the effect of antifouling agents, the surface of the tank is not easy to be contaminated, which can significantly reduce the frequency of manual cleaning, saving manpower and time costs. When cleaning is required, the surface treated with antifouling agents is easier to clean, and dirt is not easy to adhere firmly, which can improve cleaning efficiency. Antifouling agents can protect tank materials, reduce corrosion and wear, extend the service life of equipment, prevent microorganisms from multiplying in large numbers on the surface of the tank, and help maintain good Improve water quality and create a healthier environment for farmed organisms. Since cleaning becomes easier, the reduction in cleaning and maintenance time means that the farming facilities can have more time for production, improving overall efficiency, reducing the need for frequent brushing, reducing the labor intensity of workers, improving working conditions, reducing the interference and stress response caused by frequent cleaning to farmed organisms, and being beneficial to the growth and health of organisms. The coating roller 304 can ensure that the antifouling agent is evenly distributed on the surface of the farming platform body 2 to form a consistent coating, avoiding the situation where the local coating is too thick or too thin, thereby improving the consistency of the antifouling effect. Compared with manual application, the coating roller 304 can complete the application work more quickly, saving time and labor costs. Uniform application can reduce the waste of antifouling agent.The limited antifouling agent can be more fully utilized, and the rotation of the rotating disk 305 can drive the rectangular trough 306 connected to the eccentric part to make horizontal reciprocating motion, and randomly drive the sliding rod 307 fixedly connected to it to make horizontal reciprocating motion inside the first cylinder 308, and then the antifouling agent in the first cylinder 308 is injected into the coating roller 304 through the connecting pipe 309, so as to prevent the situation of insufficient antifouling agent.

[0062] The following is the working process of auxiliary maintenance agencies to remove sleep floaters:

[0063] When in use, the driver drives the second rotating column 410 to rotate clockwise, and the rotation of the second rotating column 410 drives the disc 411 connected thereto to rotate together, and the rotation of the disc 411 drives the auxiliary block 412 connected thereto to rotate at its eccentric position, thereby driving the second cylinder 413 fixedly connected to the auxiliary block 412 to do up and down reciprocating motion, and the up and down reciprocating motion of the second cylinder 413 can drive the bottom plate 416 fixedly connected thereto to do up and down reciprocating motion together, and the up and down reciprocating motion of the bottom plate 416 drives the collecting cylinder 417 movably connected thereto to reciprocate up and down together, thereby collecting floating objects floating on the sea surface, and removing floating objects can reduce the deterioration of water quality caused by the decomposition of organic matter, maintain a good breeding environment, and reduce floating objects can reduce the risk of accidental ingestion or entanglement of breeding organisms, thereby protecting their health, and removing floating objects can increase the degree of sunlight penetrating the water surface, which is beneficial to the growth of plankton in the water body and improves the water body ecosystem, and removing floating objects can prevent floating objects from clogging water inlets, filtration systems and other equipment, thereby protecting Ensure the normal operation of the aquaculture system. Clean water surface is conducive to the staff to observe and monitor the aquaculture situation. Floating objects carry pathogens. Removing them can reduce the risk of disease transmission. Good environmental conditions help to improve the growth rate and survival rate of aquaculture organisms. Clean water surface improves the working environment and will increase the work enthusiasm of employees. Timely removal of organic floating objects can reduce the stench caused by decay. Timely cleaning of floating objects can prevent pollutants from further spreading to the surrounding sea areas. Floating objects such as plastic bags, fishing nets, and waste will hit the surface of the FRP-reinforced UHPC structure under the action of ocean currents, causing physical damage. These damages may include scratches and cracks, which may cause a decrease in structural strength in severe cases. Collecting floating objects can reduce these physical damages and extend the service life of the structure. Floating objects contain chemicals, such as chemicals decomposed from certain plastics. These substances will corrode the FRP-reinforced UHPC structure. By collecting floating objects, the contact between these corrosive substances and the structure can be reduced, protecting the structure from chemical erosion.

[0064] When the infrared sensor 401 detects that a large fish is approaching the breeding platform body 2, the second rotating column 410 is driven to rotate counterclockwise. The counterclockwise rotation of the second rotating column 410 can drive the ratchet 419 fixedly connected thereto to rotate. The rotation of the ratchet 419 drives the pawl 420 meshing therewith to rotate. The rotation of the pawl 420 drives the third cylinder 418 fixedly connected thereto to rotate. Since a belt is connected between the third cylinder 418 and the first rotating column 406, that is, the rotation of the third cylinder 418 drives the first rotating column 406 to rotate, and the first rotating column 406 rotates. The first cylinder 407 is driven to rotate together with the first cylinder 407, and since the outer surface of the first cylinder 407 is provided with a threaded groove, the first cylinder 407 rotates and the L-shaped sliding rod 408 slidably connected thereto makes a reciprocating motion inside the third cylinder 404, and then the large fish repellent is sprayed through the nozzle 405 to repel the fish. Compared with traditional methods such as using nets and sound waves, the repellent usually does not cause damage to the marine ecological environment and does not affect other marine life. The repellent can quickly act on large fish, keep them away from the breeding area, and improve the repelling efficiency.
