Description

Technical Field

[0001] The utility model relates to the technical field of a breeding cage used for aquatic product breeding. Background Art

[0002] Currently, due to technological limitations, equipment levels, and production practices, my country's marine aquaculture is almost entirely concentrated in harbors and coastal waters, leading to significant conflicts over sea use. Furthermore, with the reckless and disorderly expansion of aquaculture, its drawbacks are becoming increasingly prominent. Nearshore marine aquaculture has reached saturation, and in some areas, aquaculture density significantly exceeds the environmental carrying capacity of the marine environment. Therefore, promoting the expansion of marine aquaculture from coastal areas to offshore bays and deep-sea areas is an inevitable trend and a viable strategy for optimizing the spatial layout of marine aquaculture and promoting the transformation and upgrading of the marine aquaculture industry. However, due to the extremely harsh sea conditions in these areas, and the annual impact of typhoons on my country's coastal areas, deep-sea aquaculture is an industry severely affected by the ocean's wind and wave environment. Developing these areas requires overcoming the unknown risks associated with adverse sea conditions and extreme weather. Currently, the most commonly used and effective measure is to utilize the natural law that wave intensity decreases rapidly with increasing depth. This approach involves sinking deep-sea elevating cages to the seabed for aquaculture, or sinking the cages before a typhoon approaches, effectively mitigating the impact of adverse sea conditions and extreme weather.

[0003] The structure of the existing lifting net cage generally includes a frame and a net. The frame adopts a hollow frame with open ends made of several HDPE pipe fittings. The middle part of each HDPE pipe fitting is connected for water intake and drainage and air intake and exhaust, forming a variable buoyancy chamber. Inlet and outlet ports are provided at the top of the frame, and inlet and outlet ports are also provided at the bottom of the frame. The net is surrounded by the side wall of the frame. When this type of lifting net cage needs to sink, water is discharged into the pipe fittings through the inlet and outlet ports, and the pipe body is filled with water and sinks. When it needs to rise, the pipe body is inflated through the inlet and outlet ports to discharge the water, and the pipe body is filled with gas and floats.

[0004] However, this type of lifting cage has curved corners at all four corners because the frame is spliced with curved tee pipe fittings. This may cause water or air accumulation in the tee pipe fittings during drainage, resulting in incomplete water intake and drainage or air intake and exhaust, which in turn causes the cage to be unstable in the process of sinking and floating or tilted. It may even cause the frame to flip over and over due to excessive tilt angle, making it impossible to lift or lower.

[0005] In view of this, the inventors of this case conducted in-depth research on the lifting cage, which led to the creation of this case. Summary of the Invention

[0006] The purpose of the utility model is to provide a cage lifting device which ensures that the frame can fully drain water and exhaust air without the problem of water or air accumulation, and ensures that the cage sinks and floats smoothly without tilting.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: a lifting cage device, including a breeding box body, the breeding box body includes a frame and a net cloth installed on the frame, the frame has an upper frame body, a lower frame body and a connecting column connected between the upper frame body and the lower frame body, the upper frame body has an air port for air intake and exhaust, the lower frame body has a water port for water intake and drainage, and the upper frame body has an arc-shaped pipe body for connection at the four corners; a lifting control unit is installed on the above-mentioned arc-shaped pipe body, and the lifting control unit has a vertical pipe connected to the arc-shaped pipe body, and the above-mentioned vertical pipe is integrally formed with a water seal structure. Sealing pipe, the water seal pipe has a curved connecting channel and a vertical channel extending vertically. One end of the connecting channel is connected to the upright pipe and the other end is connected to the vertical channel. The connecting channel has a water seal structure that can form a water seal effect. The vertical channel is provided with an upper exhaust port and a lower drain port arranged upper and lower. The water seal pipe is located between the upper exhaust port and the lower drain port and is installed with a control switch that controls the conduction or cutoff of the lower drain port. The above-mentioned water seal pipe is provided with a gas blocking piece that can float up and seal the upper exhaust port. The gas blocking piece is located between the control switch and the upper exhaust port, and the part where the connecting channel is connected to the vertical channel is located between the gas blocking piece and the upper exhaust port.

[0008] The above-mentioned water seal pipe comprises an upper horizontal pipe, a lower horizontal pipe, a vertical connecting pipe and a vertical pipe. The upper horizontal pipe and the lower horizontal pipe are arranged in parallel and staggered manner, and the vertical connecting pipe is located between the upper horizontal pipe and the lower horizontal pipe. The first end of the upper horizontal pipe is connected to the upper end of the vertical pipe and is connected as one piece. The upper end of the vertical connecting pipe is connected to the second end of the upper horizontal pipe and is connected as one piece. The lower end of the vertical connecting pipe is connected to the first end of the lower horizontal pipe and is connected as one piece. The second end of the lower horizontal pipe is vertically connected to the lower end side wall of the vertical pipe and is connected as one piece. The hollow chamber of the upper horizontal pipe, the hollow chamber of the lower horizontal pipe and the hollow chamber of the vertical connecting pipe constitute the communicating channel, the hollow chamber of the vertical pipe constitutes the vertical channel, and the upper horizontal pipe and the vertical connecting pipe constitute the water seal structure.

[0011] The air blocking member is a hollow floating ball or a foam ball, and the diameter of the air blocking member is larger than the diameter of the upper exhaust port.

[0012] By adopting the above technical solution, the utility model of the lifting cage device, when the breeding box body sinks and water is added, the gas in the frame, especially the gas in the arc-shaped tube body, will be squeezed into the connecting channel along with the injected water, and then discharged from the upper exhaust port through the vertical channel, so that the upper frame is located in the arc-shaped tube body without any gas remaining, so that the water level in the upper frame will not have a free liquid surface phenomenon, and the entire frame is completely filled with water, avoiding the problem of the breeding box body tilting due to the accumulation of gas in the upper frame located in the arc-shaped tube body when the traditional breeding box body sinks, thereby ensuring the stable descent of the breeding box body; When the aquaculture box floats up to drain, the drop in the water level in the vertical pipe exerts a downward force on the curved tube body, eliminating any water accumulation in the curved tube body and allowing the entire frame to be completely and evenly vented. This avoids the problem of the aquaculture box tilting due to water accumulation in the upper frame at the curved tube body when the traditional aquaculture box floats up, ensuring the smooth buoyancy of the aquaculture box. At the same time, the water seal structure in the connecting pipe ensures that seawater remains in the vertical channel to block the gas and prevent air leakage. When the frame is lowered next time, the water in the vertical channel is removed to allow for complete venting when the frame sinks. Compared to the existing technology, the frame using this structure allows the aquaculture box to fully drain water and intake and exhaust air when sinking and floating, without the phenomenon of a free liquid surface, thereby ensuring the overall smooth sinking and floating of the aquaculture box and easy operation.

[0019] This embodiment discloses a lifting cage device, such as Figure 1-5As shown, it includes a breeding box, which includes a frame and a net 1 that is stretched and installed on the frame. The frame has an upper frame 21, a lower frame 22 and a connecting column 23 connected between the upper frame and the lower frame. The upper frame 21 has an air port 211 for air intake and exhaust.

In the present utility model, the operation of the air port and the water port to make the breeding box float or sink is a well-known technology and will not be repeated here.

[0020] The innovation of the present utility model lies in that the upper frame 21 has an arc-shaped tube body 212 for connection at the four corners, and a lifting control unit is installed at the arc-shaped tube body 212. This lifting control unit has a vertical tube 3 connected to the arc-shaped tube body 212, and the vertical tube 3 is integrally connected to the arc-shaped tube body 212. A water seal pipe that can form a water seal structure is integrally formed on the vertical tube 3. The water seal pipe has a curved connecting channel and a vertical channel extending vertically. One end of the connecting channel is connected to the vertical tube, and the other end is connected to the vertical channel. There is a water seal structure in the connecting channel that can form a water seal effect. Preferably, the water seal pipe has an upper transverse tube 41, a lower transverse tube 42, a vertical connecting tube 43 and a vertical tube 44. The upper transverse tube 41 and the lower transverse tube 42 are arranged in parallel and staggered arrangement, and the vertical connecting tube 43 is between the upper transverse tube 41 and the lower transverse tube 42. The upper transverse tube 41 is higher than the vertical tube 3, and the first end of the upper transverse tube 41 is connected to the vertical tube through a connecting bend. The upper end of the vertical pipe 3 is connected and integrally formed. The vertical connecting pipe 43 is lower than the upper horizontal pipe 41. The upper end of the vertical connecting pipe 43 is connected and integrally formed with the second end of the upper horizontal pipe 41 through a connecting elbow. The lower horizontal pipe 42 is located below the vertical connecting pipe 43. The upper and lower horizontal pipes are located on both sides of the vertical connecting pipe. The first end of the lower horizontal pipe is integrally connected to the lower end of the vertical connecting pipe 43 through a connecting elbow. The lower end of the vertical connecting pipe 43 and the vertical pipe 44 are located in the lower horizontal pipe. The second end of the vertical tube 44 is longer than the distance between the upper horizontal tube and the lower horizontal tube. The second end of the lower horizontal tube 42 is vertically arranged and communicated with the lower end of the vertical tube 44, and is integrally connected. The hollow chamber of the upper horizontal tube 41, the hollow chamber of the lower horizontal tube 42 and the hollow chamber of the vertical connecting tube 43 constitute the communicating channel, the hollow chamber of the vertical tube 44 constitutes the vertical channel, and the upper horizontal tube 41 and the vertical connecting tube 43 constitute the water seal structure.

[0021] The vertical channel is provided with an upper exhaust port and a lower drain port arranged upper and lower. A water seal pipe is located between the upper exhaust port and the lower drain port and is installed with a control switch 5 that controls the conduction or cutoff of the lower drain port. A gas blocking component 6 that can float up and seal the upper exhaust port is provided in the water seal pipe. The gas blocking component 6 is located between the control switch and the upper exhaust port, and the portion where the connecting channel is connected to the vertical channel is located between the gas blocking component and the upper exhaust port.

[0022] Preferably, the vertical tube 44 is a tube body with an open lower end and a closed upper end. A circular air hole 441 is provided on the upper end face of the vertical tube 44. The circular air hole 441 is the upper exhaust port, and the lower end port of the vertical tube is the lower drain port.

[0023] A ball valve for controlling the opening or closing of the lower drain outlet is installed at the lower end of the vertical pipe 44 , and its control handle is outside the vertical pipe 44 . The ball valve is the control switch 5 .

[0024] The gas blocking member 6 is a hollow floating ball or a foam ball. The gas blocking member can also be an object with buoyancy and capable of blocking the upper exhaust port. The diameter of the gas blocking member 6 is larger than the diameter of the upper exhaust port.

[0025] The utility model discloses a lifting cage device. When the aquaculture box body is sunk and water is added, the gas in the frame, especially the gas in the arc-shaped tube body, will be squeezed into the vertical tube along with the injected water, and then discharged through the upper exhaust port of the vertical tube, so that the upper frame is located in the arc-shaped tube body without gas remaining, so that the water level in the upper frame will not have a free liquid surface phenomenon. The entire frame is completely filled with water, avoiding the problem of the aquaculture box body tilting due to the accumulation of gas in the upper frame located in the arc-shaped tube body when the traditional aquaculture box body sinks, and ensuring the smooth descent of the aquaculture box body. When the water level in the vertical pipe drops, it exerts a downward force on the curved tube body, eliminating any water accumulation within the curved tube body and ensuring complete and even exhaust of the entire frame. This avoids the problem of the traditional aquaculture box tilting due to water accumulation in the upper frame located at the curved tube body when the aquaculture box floats up, ensuring the smooth buoyancy of the aquaculture box. At the same time, the water seal structure in the connecting pipe ensures that seawater remains in the vertical channel to block the gas and prevent air leakage. The next time the frame is lowered, the water in the vertical channel is removed to allow for complete exhaust of the air when the frame sinks. Compared to the existing technology, the frame with this structure ensures that the aquaculture box can fully inlet and outlet water and intake and exhaust air when sinking and floating, without the phenomenon of free liquid surface, thus ensuring the overall smooth sinking and floating of the aquaculture box and easy operation.

[0026] The utility model provides an operation method of a lifting cage device, including sinking operation and fishing operation;

[0027] The fishing operation is completed by the following operations: an air compressor is connected to the air port 211 to inject gas into the frame, the gas inflates the frame from top to bottom, the seawater in the frame is squeezed out through the water port, and the water in the upper horizontal pipe 41 and the vertical pipe 3 is discharged downward together with the water level in the upper frame dropping, and a downward force is exerted on the arc tube body 212 so that there is no water accumulation in the arc tube body 212. The breeding box steadily drains the water in the frame from top to bottom and floats up steadily. At the same time, the vertical connecting pipe, the lower horizontal pipe and the vertical pipe are affected by the height difference so that the water inside cannot be discharged and is retained inside for sinking and exhaust. At this time, the lifting control unit is in the air blocking state. Figure 4 As shown, the gas in the upper frame cannot be discharged from the lifting control unit;

[0028] The sinking operation is completed by the following operations: when the fishing operation is completed and the aquaculture box needs to be sunk, first turn on the control switch 5, such as Figure 5 As shown, the water in the lower horizontal pipe, the vertical connecting pipe and the vertical pipe flows downward and is discharged through the lower drain port, the control switch 5 is closed, the gas blocking piece 6 falls downward, the upper exhaust port is connected, seawater flows in from the water port, the water level in the frame gradually rises, the breeding box body also gradually sinks, the gas in the frame is discharged from the air port, and the gas at the arc tube body is affected by the rising water level and squeezed into the vertical pipe 3, the upper horizontal pipe 41, the vertical connecting pipe 43, the lower horizontal pipe 42 and the vertical pipe 44, and finally discharged through the upper exhaust port. The vertical pipe, the upper horizontal pipe, the vertical connecting pipe, the lower horizontal pipe and the vertical pipe are also gradually filled with water. The gas blocking piece 6 floats up due to the rising water level to block the upper exhaust port, and the gas in the frame is completely discharged. Figure 3 As shown, the breeding box body sinks to the predetermined position, completing the sinking of the breeding box body.

[0029] The above-mentioned operation method can completely discharge the gas in the pipe of the entire frame when water is injected, and the gas in the arc-shaped bend pipe can be completely discharged during gas injection, and the gas will not leak from the vertical pipe, so that there will be no free liquid surface phenomenon during the rising or sinking process of the frame, ensuring that the overall sinking and floating of the breeding box is stable. At the same time, the switch only needs to be controlled once, and the operation is simple.

[0030] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
