Description

TECHNICAL FIELD

[0001] The utility model relates to the aquaculture technical field, concretely relates to an isolation fence for aquaculture. BACKGROUND

[0002] Aquaculture refers to a kind of production activities for feeding and breeding aquatic organisms (such as fish, shellfish, crustaceans and other aquatic plants) through artificial control environment, generally including the whole process from seedling to aquatic product under artificial feeding and management.Aquaculture includes rough feeding, intensive culture and high-density intensive culture, etc.Among them, rough feeding is to put seedlings in natural water area, and to breed aquatic products completely by natural bait, such as lake reservoir fish culture and shallow sea shellfish culture, etc.Intensive culture is to breed aquatic products by feeding and fertilizing in small water body, such as pond fish culture, net cage fish culture and fence culture, etc.High-density intensive culture is to carry out high-density culture in small water body by methods such as flowing water, temperature control, oxygenation and feeding high-quality bait, so as to obtain high yield, such as high-density flow water fish culture, shrimp, etc.

[0003] In aquaculture, it is often necessary to set up a fence, which can fix fish and other aquatic organisms in a specific area to avoid loss or confusion between different varieties.The traditional fence is difficult for the breeder to observe when the underwater part is broken, resulting in the escape of fish from the damaged part or the interbreeding of different varieties, causing significant losses to the breeder.

[0004] In view of the above problems, the Chinese utility model patent with patent application number 202121715587.6 discloses a fence for aquaculture, which includes a barrier net composed of crossed round rods, the barrier net is connected with a transparent observation ball through the connecting plate at the top, the observation ball and the round rod are both provided with harmless dye, and the fences are fixedly connected through fixing nails.In specific use, if the fence is broken, the harmless dye in the round rod and the observation ball will leak and dye a certain range of water, so that the breeder can find and remedy in time, solving the problem that the underwater part of the traditional fence is difficult to find when it is broken.However, reminding the breeder of the broken fence by dyeing the water has the following obvious defects:1.Visual interference: after the water is dyed with dye, the visibility of the water area will be affected, increasing the difficulty of underwater maintenance and replacement of the fence.2.Environmental impact: although the dye used is harmless, long-term use may still have cumulative effects and have adverse effects on the water environment and aquatic organisms.3.Limited indicating effect: in the case of turbid water, the visibility of the dye may be affected, reducing its indicating effect.Meanwhile, the utility model needs to replace the whole fence when the barrier net is broken, which is not conducive to cost saving, and the fixing nails need to be removed one by one during replacement, which is not convenient to operate. SUMMARY

[0005] The utility model discloses a water area environment's water product cultivation is with the isolation fence that can show warning when breaking and does not influence the subsequent maintenance work.

[0006] The utility model discloses a water product cultivation is with the isolation fence that the technical scheme who solves its technical problem adopts: isolation fence, the fence is by the water pipe of horizontal and vertical intersection and mutual interpenetration, and the both sides and bottom of fence are fixedly connected with other fence and pond bottom through connecting piece, and the upper portion of fence is equipped with the observation mechanism who communicates with it, and the observation mechanism mainly includes observation pipe and water injection pipe, and the water injection pipe is set up in the lateral wall of observation pipe and communicates with observation pipe, and the valve is equipped on the water injection pipe, and the observation pipe is transparent material and top closed, and the indication float of color eye-catching and density less than water is equipped in observation pipe, and the top of observation pipe is equipped with the pressure relief pipe who communicates with it.

[0007] Preferably, the connecting piece for fixing the bottom of the fence to the bottom of the pond is an anchor rod, which is detachably fixed to the fence.

[0008] Preferably, the fence is provided with a protection frame on both sides and the bottom, and the fence is inserted into the protection frame, and the connecting piece is detachably fixed to the protection frame.

[0009] Preferably, the observation mechanism is detachably connected to the fence.

[0010] Preferably, the end of the pressure relief pipe away from the observation pipe is detachably fixed with a cap with a closed pipe opening.

[0011] Preferably, the observation pipe is spherical.

[0012] Preferably, the indication float is a foam or plastic observation ball.

[0013] Preferably, the end of the pressure relief pipe close to the observation pipe is provided with a limiting net.

[0014] Preferably, the fence is made of stainless steel or glass steel.

[0015] The use mode and principle of the utility model:

[0016] In specific use, the anchor rod is fixed to a specific position on the water bottom by direct driving or concrete pouring, and the fence is connected and fixed with the connecting block and bolt, and after being fixed, the observation mechanism is located above the water surface of the pond or river, and the fence is partially or entirely located below the water surface of the pond or river, then the hose connected with the water source is sleeved on one end of the water injection pipe, and the valve on the water injection pipe is opened, so that the water flows into the observation mechanism, and after the fence and the observation mechanism are filled with water, the valve on the water source and the water injection pipe is closed.

[0017] Because the enclosure and the observation mechanism are interconnected, the water flow will enter the enclosure and gradually fill the entire enclosure and observation mechanism along the direction of the water pipe under the action of gravity after entering the observation mechanism. Because the top of the observation pipe is provided with a pressure relief pipe, there is no need to worry about damage due to excessive pressure during the water injection process. In order to facilitate observation, the observation pipe is provided with a color-noticeable and density-smaller-than-water indicating float. After the water is filled, the indicating float is located at the top of the observation pipe and closely adheres to the water surface. In the subsequent use process, if the enclosure is broken, the water level in the observation pipe will rapidly decrease under the comprehensive action of atmospheric pressure and pressure difference. In the decreasing process, the indicating float floats on the water surface from closely adhering to the water surface in the observation pipe. When the water level in the enclosure is flat with the water level of the pond or river, the water pressure inside and outside the enclosure reaches balance, and the water level in the enclosure no longer changes. At this time, the water in the observation pipe is completely lost, and the indicating float is located at the bottom of the observation pipe. Breeders can discover the breakage of the underwater enclosure in time according to the change of the water level in the observation pipe and the position of the indicating float.

[0018] Compared with the prior art, the beneficial effects of the utility model are that the enclosure can timely alarm when broken, and does not affect subsequent maintenance work and water environment, and water injection of the enclosure is also beneficial to enhance the stability of the entire enclosure structure. BRIEF DESCRIPTION OF DRAWINGS

[0019] Figure 1 It is a structural schematic view of the utility model;

[0020] Figure 2 It is a structural schematic view of the observation mechanism;

[0021] The following marks are described in the drawings: enclosure 1, observation mechanism 2, observation pipe 3, water injection pipe 4, valve 5, observation ball 6, pressure relief pipe 7, anchor rod 8, protection frame 9, cap 10. DETAILED DESCRIPTION

[0022] Example 1, the following is combined with Figure 1 and Figure 2Further explanation of this utility model: An isolation enclosure for aquaculture includes an enclosure 1 composed of intersecting and interconnected water pipes. The enclosure is made of stainless steel. To enhance its strength and facilitate replacement in case of breakage, protective frames 9 are provided on both sides and the bottom of the enclosure. Slide rails are provided on the inner walls of the protective frames, allowing the enclosure to be detachably inserted into them. Anchor rods 8 are welded, threaded, or integrally formed on the protective frames, securing them to the pond bottom. Connecting pieces with bolt holes are also provided on the protective frames, each containing a bolt with a nut threaded to its bottom. These connecting pieces enable detachable fixing between enclosures. In case of breakage, the enclosure can be easily removed from the top and a new enclosure inserted from the top, eliminating the need to remove the anchor rods or the fixing between enclosures. This facilitates quick enclosure replacement. Furthermore, only the water pipes need to be replaced, without replacing the anchor rods or other components, significantly reducing costs. The upper part of the enclosure is equipped with an observation mechanism 2 connected to it. To save costs, the observation mechanism is threadedly connected to the enclosure via a connector, allowing for quick and complete disassembly and reuse in case of enclosure breakage. The observation mechanism mainly includes an observation tube 3 and a water injection pipe 4 with a built-in valve 5. For easy observation, the observation tube is spherical, made of transparent material, and closed at the top. The water injection pipe is located on the side wall of the connector between the observation mechanism and the enclosure, and is connected to the observation tube. Inside the observation tube is a colored plastic observation ball 6. The top of the observation tube is equipped with a pressure relief pipe 7 connected to it. To prevent the observation ball from overflowing from the pressure relief pipe, the pressure relief pipe is positioned near... A limiting net is installed at the end of the pipe near the observation tube. To prevent water evaporation inside the observation mechanism, a cap 10 is threadedly connected to the end of the pressure relief pipe away from the observation tube to seal the pipe opening. When water is being added to the observation mechanism, the cap is opened. After the water is filled, the cap is closed. After the cap is closed, the entire enclosure is no longer connected to the atmosphere. When the underwater part of the enclosure breaks, the water level in the observation tube will slowly drop under the action of pressure difference. It will stop dropping after it reaches a certain level. Although the water level drops slowly, the change in the indicator float from being close to the water surface to floating on the water surface, and from being close to the top of the observation tube to gradually moving away from the top of the observation tube, can also serve to alert the aquaculture farmer to the breakage of the enclosure.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
