[0024] The bottom net cage is a kind of fixed on the bottom of water body (such as lake, riverbed in nearshore sea area), used for breeding fish, shrimp, crab and other aquatic animals breeding facilities. In the actual production and research and development process, researchers found that the traditional bottom net cage mainly through the configuration of counterweight, realizes the bottom self-balancing of net cage, which greatly increases the operation difficulty of operator, and after the operator takes and places the counterweight, still needs to measure the height or water depth of net cage from the bottom of water, to confirm whether the net cage is in the bottom self-balancing state.
[0025] The present application provides a kind of bottom net cage and balancing method, to solve the technical problem of big difficulty of bottom self-balancing of bottom net cage.
[0026] Please refer to Figures 1 to 5In an embodiment of the present application, the floor type net cage comprises a floating frame 100, a net cage body 200, a ballast assembly 300, an anchoring assembly 400 and a control assembly. The floating frame 100 comprises a float pipe assembly 110, which is provided with a ballast pipe section 111. The first end of the ballast pipe section 111 is provided with an air inlet pipe 1111 and an air outlet pipe 1112. The second end of the ballast pipe section 111 is provided with a water inlet and outlet pipe 1113. The net cage body 200 is suspended below the float pipe assembly 110. The ballast assembly 300 is arranged at the bottom of the net cage body 200. The first end of the anchoring assembly 400 is connected to a preset position 600 at the bottom of the water body. The second end of the anchoring assembly 400 is connected to the float pipe assembly 110. The control assembly comprises an air compressor, an air inlet control valve 510, an air outlet control valve 520 and a water inlet and outlet control valve 530. The air compressor is connected to the air inlet pipe 1111. The air inlet control valve 510 is arranged on the air inlet pipe 1111. The air outlet control valve 520 is arranged on the air outlet pipe 1112. The water inlet and outlet control valve 530 is arranged on the water inlet and outlet pipe 1113. The preset position 600 refers to the area at the bottom of the water body for the anchoring assembly 400 to hook. In a specific embodiment, the preset position 600 can be an anchorage at the bottom of the water body.
[0027] The technical scheme of the present application can reduce the difficulty of realizing the self-balancing of the landing net cage by setting the ballast pipe section 111, the air inlet pipe 1111, the air outlet pipe 1112 and the water inlet and outlet pipe 1113 on the floating pipe assembly 110 to construct the lifting driving system. In the embodiment, the floating rack 100 is used to provide the reserve buoyancy for the landing net cage when the landing net cage floats on the water surface, and balance the gravity when the landing net cage sinks into the water. The counterweight assembly 300 is used to spread the net cage body 200 to provide the activity space for the breeding objects, and the counterweight assembly 300 can also balance the buoyancy of the floating rack 100 to ensure that the landing net cage stably floats in the water. The anchoring assembly 400 is used to anchor the net cage body 200 at a specific position, thereby avoiding that the net cage body 200 is taken away by the wind and wave flow under the extreme sea conditions, and ensuring the position stability of the net cage body 200. The control assembly is used to control the water inlet and outlet of the ballast pipe section 111. By adjusting the amount of the ballast water in the ballast pipe section 111 through the control assembly, the buoyancy of the landing net cage is adjusted, so that the landing self-balancing of the landing net cage can be realized. When the landing net cage is deployed, the operator only needs to adjust the amount of the ballast water in the ballast pipe section 111 through the control assembly, so as to adjust the buoyancy of the landing net cage, so that the landing net cage realizes the balance between the gravity and the buoyancy when it touches the bottom, thereby realizing the landing self-balancing of the landing net cage. Specifically, when the landing net cage sinks, the length of the ballast water required by the ballast pipe section 111 for the landing self-balancing of the landing net cage is calculated, the opening of the exhaust control valve 520 and the water inlet and outlet control valve 530 is controlled by the controller, and after the ballast water in the ballast pipe section 111 reaches the calculated length (at this time, the gravity of the landing net cage is slightly greater than the buoyancy), the exhaust control valve 520 and the water inlet and outlet control valve 530 are closed, so that the landing net cage can sink to the bottom of the water, and after the counterweight assembly 300 touches the bottom, the landing net cage loses the redundant part of the gravity, realizes the balance between the gravity and the buoyancy, and finally realizes the landing self-balancing of the landing net cage. When the landing net cage floats up, the opening of the air inlet control valve 510 and the water inlet and outlet control valve 530 is controlled by the controller, and the ballast water in the ballast pipe section 111 is discharged by starting the air compressor, so as to increase the buoyancy of the landing net cage and make the landing net cage float up. The landing net cage is applied to the breeding equipment technical field such as the breeding net cage.

[0045] Specifically, the buoyancy calculation process of the floating frame 100 is as follows: first, the displacement of the pipe material used to make the inner floating pipe 112, the outer floating pipe 113 and the handrail pipe 115 per unit length is measured by the displacement method , according to the total length of the pipe material required to make the inner floating pipe 112, the outer floating pipe 113 and the handrail pipe 115 , calculate the total buoyancy of the pipe material parts , the specific formula is as follows:
[0046] Then, the displacement of a single auxiliary part (such as the connecting bracket 114) is measured by the weighing method , according to the total number of auxiliary parts calculate the total weight of the auxiliary parts , the specific formula is as follows:
[0047] The buoyancy calculation process of the net cage body 200 is as follows: the displacement of the netting used to make the net cage body 200 per unit area is measured by the displacement method , according to the total area of the netting required to make the net cage body 200 calculate the total buoyancy of the netting parts , the specific formula is as follows:
[0048] Thus, the total buoyancy of the bottom net cage can be obtained is:
[0049] S300, according to the buoyancy of the floating frame 100 and the net cage body 200, the weight of the anchoring assembly 400 that the weight assembly 300 of the bottom net cage needs to overcome when sinking to the bottom of the water, and the weight of the anchoring assembly 400 that the weight assembly 300 of the bottom net cage needs to overcome when sinking to the bottom of the water. Calculate the weight of the ballast water required by the ballast pipe section 111.
[0050] Specifically, take times of the gravity redundancy, calculate the gravity of the ballast water required by the sinking of the net cage on the ground , the specific formula is as follows:
[0051] S400, according to the gravity of the ballast water required by the ballast pipe section 111, calculate the length of the ballast water required by the ballast pipe section 111.
[0052] By measuring, the inner diameter of the inner floating pipe 112 and the outer floating pipe 113 is , calculate the length of the ballast water required by the ballast pipe section 111 , the specific formula is as follows:
[0053] It should be noted that because the counterweight 310 of the matching assembly 300 will lose part of the gravity when it touches the bottom, therefore, in order to ensure that the net cage on the ground can realize self-balance when the counterweight 310 touches the bottom, when calculating the gravity of the ballast water, should take times of the gravity redundancy, wherein, 1< x < 1.1.
[0054] In addition, after step S300, the gravity of the counterweight assembly 300 also needs to be checked; Specifically, take times of the gravity redundancy, verify , if , take ; then, by adjusting the weight of the counterweight 310, repeat step S300 until . It should be noted that in addition to meeting the above formula, the gravity of the counterweight system should also meet the minimum gravity requirement of the net cage body 200 to be expanded.
