Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine aquaculture net cage, in particular to a marine aquaculture net cage floating body structure. BACKGROUND

[0002] The marine aquaculture net cage refers to the net cage that can be used in seawater. In order to fix the net cage in the sea, the anchor cable fixing is a common way, generally one end of the anchor cable is fixed to the seabed, and the other end is fixed with the net cage.

[0003] However, the existing part of the net cage has the function of sinking and floating, when there is a strong wind, the net cage can be sunk below the water surface, and after the strong wind, the net cage is lifted above the horizontal plane. Then if the anchor cable is directly connected with the net cage, when the net cage is sunk to the bottom of the water, the anchor cable cannot be in a straight state, so that the net cage under the water cannot be in a relatively stable state.

[0004] Therefore, there is an urgent need in the art for a new type of marine aquaculture net cage floating body structure to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide a marine aquaculture net cage floating body structure to solve the above problems existing in the prior art, which can provide certain resistance to the rotation of the suspension body and the net cage body, thereby improving the stability of the suspension body and the net cage body.

[0006] To achieve the above purpose, the present application provides the following scheme: The present application discloses a marine aquaculture net cage floating body structure, which comprises a net cage body, a suspension assembly is fixed on the net cage body, the suspension assembly comprises a suspension body, a limiting pulley set is arranged at the lower end of the suspension body, the limiting pulley set comprises at least one limiting pulley, one anchor cable body is connected to all the limiting pulleys in each limiting pulley set, and a floating counterweight is arranged at one end of the anchor cable body.

[0007] Preferably, the net cage body comprises two net cage cables, the two net cage cables are distributed vertically, and a net cage net is fixed between the two net cage cables.

[0008] Preferably, a plurality of net cage counterweights are arranged at the lower end of the net cage body.

[0009] Preferably, a plurality of vertical support rods are fixed on the net cage net.

[0010] Preferably, the net cage body is a multi-prism structure, and one suspension body is fixed at each corner of the upper surface of the net cage body.

[0011] Preferably, the suspension body is provided with a water pipe interface, the water pipe interface is used for connecting a water pipe, and the water pipe is connected with a water pump.

[0012] Preferably, the suspension body is a net cage float or a net cage buoy, and an upper surface of the net cage float is a device platform.

[0013] Preferably, the net cage float is made of concrete material and has a hollow structure.

[0014] Preferably, the device platform is provided with a power generation device and working equipment, the power generation device is electrically connected with the working equipment, and the power generation device provides electric energy for the working equipment.

[0015] Preferably, the device platform is provided with a water baffle.

[0016] The present application has the following technical effects relative to the prior art: In the present application, the net cage body and the suspension body are fixedly connected, the lower end of the suspension body is fixed with a limiting pulley block, and the anchor cable body is connected to the limiting pulley block. Due to the gravity of the float counterweight, the anchor cable body can be always pulled tight, so that the anchor cable body is in a straight state. Since the limiting pulley block, the suspension body and the net cage body are in a relatively fixed relationship, the anchor cable body can always pull the suspension body and the net cage body tight to prevent displacement.

[0017] Further, the net cage float or the net cage buoy in the present application is provided with a water pipe interface. When a strong wind comes, sea water can be injected into the net cage float or the net cage buoy through the water pipe interface, so that the net cage body and the net cage float or the net cage buoy sink to avoid the strong wind. After the strong wind passes, the sea water in the net cage float or the net cage buoy is pumped out by a water pump, so as to enhance the buoyancy of the net cage float or the net cage buoy, so as to make the net cage float or the net cage buoy float on the water surface. By injecting and pumping water into the net cage float or the net cage buoy, the buoyancy of the net cage float or the net cage buoy is adjusted to control the sinking and floating, so as to avoid strong wind and waves.

[0018] Further, the suspension body is fixed to the upper net cage cable, so that the net cage body is in a suspended state, and the net cage counterweight is connected to the lower net cage cable through a rope, so that the net cage body is pulled to be in an unfolded state in the vertical direction. In combination with the pulling effect of the upper anchor cable body on the suspension body through the limiting pulley block, the net cage body is in a completely unfolded state, and the net cage body is in a maximum volume state.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the protection scope of the present application.

[0022] The purpose of the present application is to provide a floating body type structure of marine aquaculture net cage to solve the problems in the prior art, which can provide certain resistance to the rotation of the suspended body and the aquaculture net cage body, thereby improving the stability of the suspended body and the aquaculture net cage body.

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment One As Figures 1-2As shown, the present embodiment provides a marine culture net cage floating body structure, which comprises a culture net cage body 1, the inside of the culture net cage body 1 is used for containing fish to be cultured. The culture net cage body 1 is fixed with a suspension assembly, the suspension assembly comprises a suspension body, when the suspension body is provided with more than one, each suspension body is uniformly distributed at the upper end edge of the culture net cage body 1. The lower end of the suspension body is provided with a limiting pulley set 4, the limiting pulley set 4 comprises at least one limiting pulley, and generally only 1-2 can be provided. All limiting pulleys in each limiting pulley set 4 are commonly connected with an anchor cable body 5, that is, the middle part of the anchor cable body 5 will pass through each limiting pulley in turn. The end of the anchor cable body 5 with an anchor head is fixed to the seabed, and the other end of the anchor cable body 5 is provided with a floating counterweight 6, which can adopt solid iron blocks, concrete blocks or stones and other weights that can always be in a sinking state in water.

[0025] In actual use, the end of the anchor cable body 5 with the anchor head is fixed to the seabed, and the other end is fixed with the floating counterweight 6, since the floating counterweight 6 is always in a sinking state in water, the floating counterweight 6 can always tension the anchor cable body 5, and through the anchor cable body 5, a certain tension force can be applied to the limiting pulley set 4 and the suspension body, and further, through the suspension body, a tension effect can be applied to the culture net cage body 1, so as to improve the use stability of the culture net cage body 1 and the suspension body.

[0026] In the present embodiment, the culture net cage body 1 comprises two net cage cables, the net cage cable is a closed loop rope structure, and the space between each net cage cable is fixed with a net cage net by a rope, the net cage net is a fishnet of existing plastic material. The two net cage cables are distributed up and down, and the periphery gap between the two net cage cables is also fixed with a net cage net by a rope. The space surrounded by each net cage cable and the net cage net is used for feeding fish, and each suspension body can also be fixed on the upper net cage cable by a rope.

[0027] In the present embodiment, the net cage cable at the lower end of the culture net cage body 1 is fixedly connected with a plurality of net cage counterweights 7, from Figure 1 It can be seen that three net cage counterweights 7 are specifically connected. The net cage counterweight 7 is the same as the floating counterweight 6, which can adopt solid iron blocks, concrete blocks or stones and other weights that can always be in a sinking state in water. Each suspension body is fixed to the upper net cage cable, thereby driving the culture net cage body 1 to be in a suspended state, and each net cage counterweight 7 is connected to the lower net cage cable by a rope, thereby pulling the culture net cage body 1 to be in an unfolded state in the vertical direction. In combination with the tension effect of the upper anchor cable body 5 on each suspension body through the limiting pulley set 4, the culture net cage body 1 is in a completely unfolded state, at this time, the culture net cage body 1 is in a maximum volume state.

[0028] In the embodiment, a plurality of vertical support rods are fixed on the net cover of the net cage by ropes. The support rods can be rigid rods, including but not limited to steel pipe structures. The support rods are arranged to keep the net cover between the upper and lower net cables in a vertical suspended state, avoiding horizontal water flow from driving the net cover to move greatly in the horizontal direction, thereby affecting the volume of the net cage body 1.

[0029] In the embodiment, the net cage body 1 is a multi-prism structure, from Figure 1 It can be seen that three suspension bodies are provided, so the net cage body 1 is a three-prism structure, and one suspension body is fixed at each corner of the upper surface of the net cage body 1. From Figure 2 It can be seen that although the anchor cable body 5 passes through the limiting pulley block 4, it can provide a component force away from the net cage body 1 for the limiting pulley block 4, so as to pull the suspension body to move away from the net cage body 1, and cooperate with the vertical stretching action of the three net cage counterweights 7 connected to the three corners of the lower net cable, so as to pull the net cage body 1 into a three-prism structure.

[0030] In the embodiment, a water pipe interface is provided on the suspension body, which is used to connect a water pipe. A water pump is connected to the water pipe. The water pump can be used to fill seawater into the suspension body or to pump seawater out of the suspension body, so as to adjust the suspension state of the suspension body. Of course, when the water filling or pumping work is not performed, a sealing plug or sealing cover can be installed at the water pipe interface, so as to ensure the sealing of the cavity in the suspension body.

[0031] When a strong wind comes, seawater can be injected into the suspension body to make the suspension body and the net cage body 1 sink, so as to avoid the strong wind. After the strong wind passes, the seawater in the suspension body is pumped out by the water pump, so as to increase the buoyancy of the suspension body, so as to make the suspension body float on the water surface.

[0032] In the embodiment, the suspension body is a net cage float 2 or a net cage buoy 3. The suspension assembly includes at least three suspension bodies, that is, the suspension assembly can be all net cage floats 2, or all net cage buoys 3, or both net cage floats 2 and net cage buoys 3, and the specific number of the two can be selected according to actual needs. The upper surface of the net cage float 2 is a device platform, which can be used to place some devices required by the net cage body 1, and can also provide a landing platform for some unmanned aerial vehicles or aircrafts. The net cage buoy 3 can be a commercially available existing commercial buoy on the market. Figure 1 It can be seen from

[0033] It can be seen from Figure 1As can be seen, the cage buoy 3 is an existing spherical commercial buoy, with a limiting pulley at its lower center. The lower surface of the cage float 2 has two limiting pulleys: one located at the bottom center of the suspended body, and the other at the bottom edge. All the limiting pulleys are arranged in a straight line. In actual use, because the middle part of the anchor cable body 5 passes through the two limiting pulleys, the anchor cable body 5 between the two limiting pulleys is in a taut, straight state, thus providing a limiting effect between the limiting pulleys and the anchor cable body 5. The taut anchor cable body 5 restricts the rotation of the limiting pulley group 4, thereby restricting the rotation of the suspended body fixedly connected to the limiting pulley group 4, and further limiting the rotation of the aquaculture cage body 1 fixedly connected to the suspended body.

[0034] In this embodiment, the cage float 2 is made of concrete and has a hollow structure, thereby enabling the concrete cage float 2 to suspend. There are two reasons for using concrete to make the cage float 2: firstly, it has a robust structure and a long service life; secondly, it has low manufacturing and usage costs. Of course, those skilled in the art can replace it with cage floats made of other materials according to actual needs, and it is not limited to this one.

[0035] In this embodiment, a power generation device and a working device are installed on the equipment platform. The power generation device is electrically connected to the working device, and the power generation device provides power to the working device.

[0036] The power generation equipment includes existing wind power generation equipment and / or solar power generation equipment.

[0037] A wind power generation device includes a wind turbine, the center of which is fixedly connected to the input shaft of a wind turbine generator. The wind turbine generator can be fixed to the equipment platform via a generator bracket. The wind turbine generator is electrically connected to the rectifier of the wind turbine generator controller, and the wind turbine generator controller is electrically connected to a battery. The battery is electrically connected to the operating equipment via wires and an inverter. In actual use, the wind drives the wind turbine to rotate, which in turn drives the wind turbine generator to generate electricity. The wind turbine generator converts the generated alternating current (AC) to direct current (DC) through a rectifier, and the DC is stored in the battery. When the operating equipment needs power, the battery's electrical energy is converted back to AC by the inverter to supply power to the equipment.

[0038] A solar power generation device includes solar photovoltaic panels, a solar controller, and a battery. Both the solar photovoltaic panels and the battery are electrically connected to the solar controller. The solar photovoltaic panels convert light energy into electrical energy and transmit the electrical energy to the solar controller. The solar controller regulates and rectifies the current before sending it to the battery for storage.

[0039] The wind power generation devices and solar power generation devices described above are all existing technologies, so their details will not be elaborated further. Of course, those skilled in the art can add other types of power generation devices based on these, and are not limited to these two.

[0040] The working equipment includes anemometers, temperature sensors, GPS positioning devices, and underwater cameras. The anemometer measures seawater wind speed; if the wind speed is too high, it notifies staff to inject seawater into the floating structure to cause it to sink. The temperature sensor monitors the ambient temperature. The GPS positioning device reports the equipment's location to staff in real time, preventing them from losing track of the equipment. The underwater camera records underwater images and transmits them to the land-based control terminal, allowing staff to understand the underwater situation. All of these devices are electrically connected to the land-based control terminal, enabling staff in the control room to monitor the surrounding environment of the floating aquaculture cage structure in real time.

[0041] In this embodiment, water baffles are installed around the equipment platform to prevent seawater from washing onto the platform and damaging the working equipment.
