Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a floating cage platform. Background Art

[0002] Due to long-term extensive management and high-density aquaculture, the seawater in the nearshore shallow water aquaculture area is seriously polluted, pests and diseases are frequent, and the quality of aquatic products has declined. The deep and deep sea water is rich in nutrients, with sufficient water exchange and excellent water quality, and is a natural marine pasture. Therefore, in order to reduce the impact of aquaculture on the nearshore sea area and achieve healthy and sustainable development of marine aquaculture, it is imperative to develop the deep and deep sea aquaculture industry.

[0003] The researchers have conducted a relatively thorough study on the sinking and floating control of traditional HDPE frame gravity cages.

The existing technologies mostly sink the cage by injecting water into the buoy, and float the cage by inflating and draining the buoy. The above patented technologies are all applied to traditional HDPE frame gravity cages, and have the following disadvantages: poor stability during the sinking and floating process, uneven water inflow easily leads to cage deformation, the tilt of the cage causes the air holes to sink into the water to form a water seal, resulting in the inability to discharge the buoy gas, etc. There is no sinking and floating control system applied to deep-sea steel structure truss cages.

[0027] Due to long-term extensive management and high-density aquaculture, the seawater in the nearshore shallow water aquaculture area is seriously polluted, pests and diseases are frequent, and the quality of aquatic products has declined. The deep and deep sea water is rich in nutrients, with sufficient water exchange and excellent water quality, and is a natural marine pasture. Therefore, in order to reduce the impact of aquaculture on the nearshore sea area and achieve healthy and sustainable development of marine aquaculture, it is imperative to develop the deep and deep sea aquaculture industry.

[0028] The researchers have conducted a relatively thorough study on the sinking and floating control of traditional HDPE frame gravity cages. Patent CN201611025868.2 discloses an isobaric-controlled sinking and floating aquaculture cage and control method, in which multiple isolation compartments are connected by pipes to form an isobaric sinking and floating control body, and the sinking and floating of the cage is achieved by injecting water or inflating the sinking and floating control body with a water pump or an air pump; Patent CN202021534787.8 discloses an automatic sinking and floating control device for deep-sea aquaculture cages, in which an air bag is arranged in each floating tube of the cage, and the air volume in the air bag is controlled by the air pump to make the water flow in or out of the floating tube to achieve the sinking and floating of the cage; Patent CN202310123466.X discloses a deep-sea remote-controlled sinking and floating aquaculture cage, in which a number of buoyancy barrels are arranged on the upper edge of the cage, and the buoyancy barrels are connected to the air pump through a valve, and the gas pressure in each buoy is individually controlled to achieve water inlet and outlet of the buoy, thereby achieving the sinking and floating of the cage. The existing technologies mostly sink the cage by injecting water into the buoy, and float the cage by inflating and draining the buoy. The above patented technologies are all applied to traditional HDPE frame gravity cages, and have the following disadvantages: poor stability during the sinking and floating process, uneven water inflow easily leads to cage deformation, the tilt of the cage causes the air holes to sink into the water to form a water seal, resulting in the inability to discharge the buoy gas, etc. There is no sinking and floating control system applied to deep-sea steel structure truss cages.

[0029] Therefore, there is an urgent need for a new type of floating cage platform to solve the problem that the existing floating cage platform has poor stability during the sinking and floating process, which easily causes the cage platform to tilt during filling and drainage.

[0030] In order to solve the above problems, the utility model proposes a floating cage platform.

[0031] See also Figure 1 and Figure 2In one embodiment of the utility model, the floating cage platform includes a platform body 1 and a flooding and drainage assembly 2; the platform body 1 includes a port side 11 and a starboard side 12, and the port side 11 and the starboard side 12 are symmetrically arranged based on the centerline plane of the platform body 1; N left ballast tanks 111 are arranged inside the port side 11, and N right ballast tanks 121 are arranged inside the starboard side 12, and the serial numbers of the N left ballast tanks 111 are arranged in the direction from the bow side to the stern side of the platform body 1. The serial numbers of the N right ballast tanks 121 increase in sequence from the bow to the stern of the platform body 1; the k-th left ballast tank 111 and the k-th right ballast tank 121 are symmetrically arranged based on the centerline plane; the filling and drainage assembly 2 is connected to the N left ballast tanks 111 and the N right ballast tanks 121 respectively; the filling and drainage assembly 2 is used for synchronous filling and drainage of the k-th left ballast tank 111 and the (N+1-k)-th right ballast tank 121; 1≤k≤N.

[0032] It should be noted that the platform body 1 can be regarded as a hull; the centerline plane is a longitudinal plane passing through the centerline of the hull and perpendicular to the base surface, and the centerline plane divides the hull (i.e., the platform body 1) into two symmetrical parts, the port side 11 and the starboard side 12. In addition, it should be noted that the injection and drainage assembly 2 may include but is not limited to pumps, valves, pipes, control modules (controllers, circuits, electronic components), etc. that cooperate with each other to realize the injection and drainage functions. The injection and drainage assembly 2 will be further described in the subsequent embodiments, and the type of the injection and drainage assembly 2 is not limited here.

[0033] The technical solution of the utility model is to arrange the port side 11 and the starboard side 12, the left ballast tank 111 and the right ballast tank 121 symmetrically based on the centerline plane of the platform body 1, so that the center of gravity of the platform body 1 is located on the centerline plane, and it is not easy to tilt to either the port side 11 or the starboard side 12 during non-sinking and floating; during the sinking and floating process, the injection and drainage component 2 synchronously injects and discharges water to the kth left ballast tank 111 and the N+1-kth right ballast tank 121. Since the connecting line of the kth left ballast tank 111 and the N+1-kth right ballast tank 121 is closer to the center of gravity of the platform body 1, the synchronous injection and drainage to the kth left ballast tank 111 and the N+1-kth right ballast tank 121 can make the impact on the platform center smaller, thereby reducing the possibility of the floating cage platform tilting during the injection and drainage process. Specifically, for the convenience of explanation, taking N=6, that is, the number of the left ballast tanks 111 and the right ballast tanks 121 is 6 as an example, when k=1, at this time, the kth left ballast tank 111 is the first left ballast tank 111, and the N+1-kth right ballast tank 121 is the sixth right ballast tank 121, that is, the first left ballast tank 111 that needs to be filled and drained is close to the bow side of the port side 11 of the platform body 1, and the sixth right ballast tank 121 that needs to be filled and drained is close to the bow side of the port side 11 of the platform body 1. Close to the stern side of the starboard side 12 of the platform body 1; compared with the remaining combinations of the left ballast tanks 111 and the right ballast tanks 121 (such as the combination of the first left ballast tank 111 and the fourth right ballast tank 121), the line between the first left ballast tank 111 and the sixth right ballast tank 121 is closer to the original center of gravity of the platform body 1, and therefore has less impact on the center of gravity of the platform body 1, thereby reducing the inclination of the floating cage platform caused by the filling and drainage operation. Similarly, when k=2, 3, 4, 5, 6 or other integer values ​​≤N, since the line between the kth left ballast tank 111 and the N+1-kth right ballast tank 121 is closer to the original center of gravity of the platform body 1 than the line of the combination of the remaining left ballast tanks 111 and the right ballast tanks 121, the simultaneous injection and drainage of the kth left ballast tank 111 and the N+1-kth right ballast tank 121 by the injection and drainage assembly 2 can also reduce the impact on the center of gravity of the platform body 1, thereby also reducing the tilt of the floating cage platform during the injection and drainage process.

[0034] In addition, traditional HDPE frame gravity cage facilities are often difficult to withstand the direct attack of super typhoons due to the performance limitations of materials and structures, and the safety protection capabilities of the facilities are insufficient. As an optional implementation, the floating cage platform can be set as a truss cage platform constructed of metal profiles. Compared with HDPE frame gravity cages, truss cages constructed of metal profiles have a safer and less deformable rigid box body, which is suitable for building larger cages in aquaculture waters and can be set in deeper and farther sea areas.

[0035] In the embodiment of the utility model, since the kth left ballast tank 111 and the kth right ballast tank 121 are symmetrically arranged only based on the centerline plane, if the left ballast tank 111 and the right ballast tank 121 are biased toward the bow side or the stern side as a whole, even if the injection and drainage assembly 2 is used to simultaneously inject and drain water to the kth left ballast tank 111 and the N+1-kth right ballast tank 121, the platform body 1 will still be tilted. In order to solve the problem of how to further reduce the tilt that may occur in the platform body 1 during the injection and drainage process, please refer to Figure 1 and Figure 2 , the kth left ballast tank 111 and the (N+1-k)th right ballast tank 121 are symmetrically arranged based on the center of gravity of the platform body 1. It should be noted that the gravity line is the line connecting the center of gravity of an object and the center of gravity of the earth. In this embodiment, the gravity line of the platform body 1 is the line connecting the center of gravity of the platform body 1 and the center of gravity of the earth. In this way, after adopting the technical solution of symmetrically arranging the kth left ballast tank 111 and the (N+1-k)th right ballast tank 121 based on the center of gravity of the platform body 1, any pair of left ballast tanks 111 and right ballast tanks 121 that meet the above relationship as a whole will not affect the center of gravity of the platform body 1, thereby further reducing the tilt problem that may occur in the platform body 1 during the filling and drainage process.

[0036] In the embodiment of the present utility model, in order to solve the problem of how to place the injection and drainage assembly 2 in one of the compartments so as to simultaneously inject and drain the left ballast tank 111 of the port side 11 and the right ballast tank 121 of the starboard side 12, please refer to Figure 1 and Figure 2 The platform body 1 further includes a connecting cabin 13, through which the N left ballast tanks 111 are connected to the N right ballast tanks 121; the injection and drainage assembly 2 is arranged at least one of the left ballast tank 111, the right ballast tank 121, and the connecting cabin 13. In this way, after the connecting cabin 13 exists in the platform body 1, the left ballast tank 111 and the right ballast tank 121 are connected to each other, and the injection and drainage assembly 2 only needs to be arranged at least one of the left ballast tank 111, the right ballast tank 121, and the connecting cabin 13 to realize the injection and drainage operation of each left ballast tank 111, each right ballast tank 121, and the connecting cabin 13, which reduces the number of injection and drainage assemblies 2 required and saves costs.

[0037] In the embodiment of the utility model, in order to solve the problem of how to reduce the uneven distribution of water sources inside the connecting cabin 13, which causes the platform body 1 to have an inclination angle, the connecting cabin 13 has a left cabin and a right cabin inside; the left cabin and the right cabin are symmetrically arranged based on the midline plane. In this way, the connecting cabin 13 is divided into two parts, the left cabin and the right cabin. Since the left cabin and the right cabin are symmetrically arranged based on the midline plane, the influence of the left cabin and the right cabin on the center of gravity of the platform body 1 during the filling and drainage process can also be reduced.

[0038] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A left pump cabin 112 is also provided inside the port side 11, and a right pump cabin 122 is also provided inside the starboard side 12. The left pump cabin 112 is connected with the right pump cabin 122 through the connecting cabin 13. The left pump cabin 112 is also connected with the left ballast tank 111, and the right pump cabin 122 is also connected with the right ballast tank 121; both the left pump cabin 112 and the right pump cabin 122 are provided with a first water injection port 14 and a first drainage port 15; the injection and drainage assembly 2 includes a pump body 21, which is provided in the left pump cabin 112 or the right pump cabin 122, the water inlet of the pump body 21 is connected with one of the first water injection ports 14, and the water outlet of the pump body 21 is connected with one of the first drainage ports 15. In order to solve the problem of how to measure and adjust the water pressure and flow of the pump body 21 in real time, the water inlet and the water outlet of the pump body 21 are both provided with pressure sensors 22; the pressure sensors 22 are used to measure the pressure values ​​of the water inlet and the water outlet of the pump body 21 and calculate the flow value of the pump body 21. Thus, in this embodiment, the injection and drainage assembly 2 includes a pump body 21, the water inlet of the pump body 21 is used to pump an external water source from the first water injection port 14, so that the external water source enters the left pump cabin 112 or the right pump cabin 122; the water outlet of the pump body 21 is used to discharge the internal water source to the first drainage port 15. At the same time, in order to facilitate the measurement and adjustment of the water pressure and flow of the pump body 21, so as to control the total amount of injection and drainage, the water inlet and the water outlet of the pump body 21 are both provided with pressure sensors 22, and the pressure sensors 22 can directly measure the water pressure on both sides of the water inlet and the water outlet of the pump body 21; after knowing the water pressure on both sides of the pump body 21, the flow at the water outlet of the pump body 21 can be obtained according to the simplified form of the Bernoulli equation in fluid mechanics. Therefore, the pressure sensor 22 can be used to calculate the total amount of injection and drainage of the pump body 21, so that the operator or computer can compare the calculated total amount of injection and drainage with the required total amount of injection and drainage to determine whether the injection and drainage operation is completed.

[0039] In the embodiment of the present invention, in order to solve the problem that the ballast tanks far from the left pump room 112 and the right pump room 122 cannot be filled and drained synchronously with the ballast tanks close to the left pump room 112 and the right pump room 122, please refer to Figure 1 and Figure 2The injection and drainage assembly 2 also includes a connecting channel 23, which includes a left channel 231, a right channel 232, and a transverse channel 233; the left channel 231 passes through each left ballast tank 111 and the left pump cabin 112, the right channel 232 passes through each right ballast tank 121 and the right pump cabin 122, the transverse channel 233 passes through the left pump cabin 112, the connecting cabin 13, and the right pump cabin 122, and the two ends of the transverse channel 233 are respectively connected to the left channel 231 and the right channel 232; the water inlet and the water outlet of the pump body 21 are also connected to the left channel 231, the right channel 232, and the transverse channel 233. At least one of them is connected; the left channel 231 is provided with N first water outlets 2311, and the N first water outlets 2311 are arranged in the N left ballast tanks 111 in a one-to-one correspondence; the right channel 232 is provided with N second water outlets 2321, and the N second water outlets 2321 are arranged in the N right ballast tanks 121 in a one-to-one correspondence; the cross channel 233 is provided with two third water outlets 2331, one of the two third water outlets 2331 is arranged in the left area of ​​the connecting cabin 13, and the other of the two third water outlets 2331 is arranged in the right area of ​​the connecting cabin 13. It should be noted that the N of the N first water outlets 2311 and the N second water outlets 2321 in this embodiment is consistent with the N of the N left ballast tanks 111 and the N right ballast tanks 121 in the above embodiment. Thus, in this embodiment, the left channel 231 passes through each left ballast tank 111, the right channel 232 passes through each right ballast tank 121, and the transverse channel 233 passes through the connecting chamber 13. Since each left ballast tank 111, each right ballast tank 121, and the channels in the connecting chamber 13 are all provided with corresponding water outlets, the pump body 21 only needs to be connected to at least one of the left channel 231, the right channel 232, and the transverse channel 233 to achieve the effect of synchronously filling and draining water to each left ballast tank 111, each right ballast tank 121, and the connecting chamber 13. In this way, the degree of synchronization of filling and draining water to each ballast tank and the connecting chamber 13 is improved. In addition, since the lateral dimension of the connecting cabin 13 is very large, when the platform body 1 tilts left or right, if the left side or right side of the platform body 1 is higher, the connecting cabin 13 may not be able to drain completely by relying on only one water inlet and outlet. In order to avoid the above situation, in this embodiment, one third water outlet 2331 is provided in the left area and the right area of ​​the connecting cabin 13, for a total of two third water outlets 2331, so as to drain the water source in the connecting cabin 13 as much as possible.

[0040] Specifically, to facilitate understanding of the above embodiment, the case of N=6 in the above embodiment is continued as an example. At this time, the left channel 231 is provided with 6 first water outlets 2311, and the 6 first water outlets 2311 are arranged one-to-one in the 6 left ballast tanks 111; similarly, the right channel 232 is provided with 6 second water outlets 2321, and the 6 second water outlets 2321 are arranged one-to-one in the 6 right ballast tanks 121, thereby ensuring that each left ballast tank 111 and each right ballast tank 121 is provided with a water outlet, and two water outlets are provided in the connecting cabin 13, so that the pump body 21 can realize unified filling and drainage operations through various channels no matter where it is arranged in the left ballast tank 111, the right ballast tank 121, and the connecting cabin 13.

[0041] In the embodiment of the present utility model, in order to solve the problem that the pump body 21 in the above embodiment cannot only fill and drain water to a specific ballast tank or connecting chamber 13, please refer to Figure 1 and Figure 2 The water inlet and outlet of the pump body 21, each first water outlet 2311, each second water outlet 2321, and the third water outlet 2331 are all provided with a valve body 24. In this way, after each water outlet is provided with a valve body 24, an operator or a computer system can control the opening and closing of the valve body 24 to achieve the effect of filling and draining water only to the required ballast tank.

[0042] In the embodiment of the present utility model, in order to avoid the problem that the platform body 1 cannot be smoothly filled and drained when the filling and draining assembly 2 fails, please refer to Figure 1 and Figure 2 The floating cage platform includes at least two injection and drainage components 2, each of which is connected to N left ballast tanks 111 and N right ballast tanks 121 respectively; at least two injection and drainage components 2 are standby for each other. In this way, the existence of at least two injection and drainage components 2 makes the design redundancy of the injection and drainage function higher. Even if one of the injection and drainage components 2 fails, the remaining injection and drainage components 2 can still perform the injection and drainage operation normally, thereby improving the reliability of the injection and drainage function.

[0043] In an embodiment of the utility model, the floating cage platform also includes a driving module; the driving module is electrically connected to the injection and drainage component 2, and the driving module pre-stores N ballast tank pair information, and the kth ballast tank pair information includes the kth left ballast tank 111 and the (N+1-k)th right ballast tank 121; the driving module is used to send several ballast tank pair information to the injection and drainage component 2 in a preset order; the injection and drainage component 2 is used to synchronously perform injection and drainage operations on the corresponding left ballast tank 111 and right ballast tank 121 according to the received ballast tank pair information.

[0044] It should be noted that the driving module can be an existing MCU (Microcontroller Unit) microcontroller unit or a corresponding module on a single chip computer with functions such as information storage, simple data processing, signal input and output, etc.

[0045] In this embodiment, for ease of understanding, the case of N=6 in the aforementioned embodiment is continued as an example. At this time, the driving module pre-stores 6 ballast tank pair information. When k=1, the kth ballast tank pair information is the first ballast tank pair information, which includes the kth left ballast tank 111 and the (N+1-k)th right ballast tank 121, that is, the first left ballast tank 111 and the sixth right ballast tank 121; when k=2, the second ballast tank pair information includes the second left ballast tank 111 and the fifth right ballast tank 121; similarly, it can be known that when k=3, 4, 5, 6, the ballast tank pair information corresponds to the kth left ballast tank 111 and the (N+1-k)th right ballast tank 121 respectively. During operation, taking the preset order of the first ballast tank pair information, the sixth ballast tank pair information, the third ballast tank pair information, and the fourth ballast tank pair information as an example, at this time, the driving module sends the first ballast tank pair information to the injection and drainage component 2, and the injection and drainage component 2 starts to perform injection and drainage operations on the first left ballast tank 111 and the sixth right ballast tank 121 synchronously after receiving the first ballast tank pair information; then the driving module sends the sixth ballast tank pair information to the injection and drainage component 2, and the injection and drainage component 2 starts to perform injection and drainage operations on the sixth left ballast tank 111 after receiving the sixth ballast tank pair information. The injection and drainage operations are performed synchronously with the first right ballast tank 121; then the driving module sends the information of the third ballast tank pair to the injection and drainage component 2, and the injection and drainage component 2 starts to perform injection and drainage operations on the third left ballast tank 111 and the fourth right ballast tank 121 synchronously after receiving the information of the third ballast tank pair; finally, the driving module sends the information of the fourth ballast tank pair to the injection and drainage component 2, and the injection and drainage component 2 starts to perform injection and drainage operations on the fourth left ballast tank 111 and the third right ballast tank 121 synchronously after receiving the information of the fourth ballast tank pair; finally, the entire injection and drainage operation is completed.

[0046] Thus, in this embodiment, the driving module can send the information of the stored ballast tank pairs to the injection and drainage component 2 in a preset order, and the injection and drainage component 2 can synchronously perform injection and drainage operations on the corresponding left ballast tank 111 and right ballast tank 121 according to the received ballast tank pair information. After the driving module is adopted, by pre-storing N ballast tank pair information and setting a preset order, the driving module can automatically send the information of the ballast tank pair to the injection and drainage component 2 as long as the driving module is started, and the injection and drainage component 2 automatically completes the injection and drainage operations without too much manual intervention, thereby improving the automation of the floating cage platform. In addition, the injection and drainage component 2 synchronously injects and drains water to the left ballast tank 111 and the right ballast tank 121 in each ballast tank pair, thereby ensuring that the injection and drainage volume in the left ballast tank 111 is consistent with the injection and drainage volume in the right ballast tank 121 as much as possible, thereby reducing the possibility of the platform body 1 tilting during the injection and drainage process.

[0047] In an embodiment of the utility model, the floating cage platform also includes a water volume monitoring module; the water volume monitoring module is electrically connected to the injection and drainage component 2 and the drive module; the water volume monitoring module is used to obtain the injection and drainage volume data of the left ballast tank 111 and the right ballast tank 121; when the injection and drainage volume data meets the preset water volume threshold condition, the water volume monitoring module is used to send a termination signal; the injection and drainage component 2 is used to suspend the injection and drainage operation upon receiving the termination signal; the drive module is used to send the next order of ballast tank pair information to the injection and drainage component 2 in a preset order upon receiving the termination signal.

[0048] It should be noted that the water volume monitoring module can be a flow meter, a liquid level sensor or other measuring device. These measuring devices can be used in conjunction with modules on existing controllers that have basic data storage and value comparison functions.

[0049] In this embodiment, the water volume monitoring module is used to obtain the filling and drainage data of the left ballast tank 111 and the right ballast tank 121, and the filling and drainage operation of the ballast tank pair is judged whether it is completed according to the filling and drainage data and the preset water volume threshold condition. If the filling and drainage operation of the ballast tank pair is completed, a stop signal is sent to make the filling and drainage component 2 suspend the filling and drainage, and the driving module sends the next order of ballast tank pair information to the filling and drainage component 2 in a preset order when receiving the stop signal. When there is no next order of ballast tank pair information that can be sent in the driving module, it indicates that all ballast tank pairs that need to be filled and drained have completed the filling and drainage operation. In this embodiment, the water volume monitoring module is used to obtain and judge the filling and drainage data. Compared with the manual judgment method, the water volume monitoring module has higher judgment accuracy and better control accuracy for the filling and drainage operation during the sinking and floating process of the floating cage platform.
