Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically a high-density shrimp pond with bottom aeration. Background Technology

[0002] With the large-scale development of aquaculture, high-density shrimp farming technology has gradually become a research hotspot. Traditional shrimp ponds mostly use surface aeration or one-sided oxygenation, which leads to uneven distribution of dissolved oxygen in the water, with insufficient dissolved oxygen at the bottom being particularly prominent, seriously affecting the growth efficiency and survival rate of shrimp.

[0003] In the existing technology, some shrimp ponds improve the shrimp's habitat by setting up fixed habitat devices (such as artificial aquatic plants). However, such devices make it inconvenient to clean the shrimp ponds later, and the accumulation of attached substances due to long-term soaking can affect the effectiveness of the device.

[0004] Based on the above-mentioned technical problems, this application provides a high-density shrimp farming pond with bottom aeration. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-density shrimp pond with bottom aeration, which solves the problem of uneven distribution of dissolved oxygen in the water of traditional shrimp ponds, as well as the technical problem of inconvenient cleaning in the later stage caused by the use of fixed artificial aquatic plants.

[0006] The present invention adopts the following solution: a high-density shrimp farming pond with bottom aeration, characterized in that it includes:

[0007] The pool body is equipped with an oxygen supply device.

[0008] Several aeration pipes are evenly distributed inside the tank, and each aeration pipe has several aeration holes. The tank is equipped with aeration branch pipes that communicate with the aeration pipes and are connected to an oxygen supply device.

[0009] The mounting frame is located at the top of the pool and above the aeration pipe and aeration branch pipe. The mounting frame is equipped with a perching area.

[0010] The adjustment component is located on the pool body and cooperates with the mounting frame to drive the mounting frame to rise and fall vertically along the side wall of the pool body.

[0011] Preferably, the mounting frame includes two first auxiliary plates and several second auxiliary plates; the several second auxiliary plates are evenly distributed along the length of the pool body, the two first auxiliary plates are symmetrically arranged with respect to the center of the second auxiliary plates, and the two first auxiliary plates and the second auxiliary plates are fixedly connected by screws and nuts.

[0012] Preferably, the habitat includes a plurality of filter brushes, and the plurality of filter brushes are detachably connected to the second auxiliary plate by means of snap fasteners.

[0013] Preferably, the adjustment component includes a telescopic member, the extended end of which is connected to the first auxiliary plate, and the other end of which is connected to the bottom of the pool.

[0014] Preferably, the telescopic component is an electric telescopic rod, a hydraulic telescopic rod, or a pneumatic telescopic rod, and all are made of stainless steel and coated with a waterproof coating.

[0015] By adopting the above technical solutions, the stainless steel telescopic components are corrosion-resistant, suitable for long-term underwater operations, extending the service life of the equipment. The electric telescopic mast supports remote control, improving the level of automation in aquaculture management.

[0016] Preferably, the oxygen supply equipment is a blower, and the aeration branch pipe is equipped with a flow regulating valve.

[0017] By adopting the above technical solution, the aeration branch pipe flow regulating valve can dynamically adjust the oxygen supply according to the stocking density, thus avoiding energy waste.

[0018] Preferably, the bottom of the pool is a funnel-shaped structure that slopes towards the center, and a suction port is provided at the lowest point, which is connected to an external circulation filtration system.

[0019] By adopting the above technical solution, the funnel-shaped structure at the bottom of the pond, combined with the central suction port, utilizes the natural flushing of water to collect and discharge uneaten feed and feces, significantly improving sewage discharge efficiency. Combined with an external circulation filtration system, it can maintain water cleanliness, extend the water change cycle, and reduce aquaculture energy consumption. The suction port is equipped with a filter screen to prevent shrimp from being discharged, and the water flow rate can be controlled by adjusting the power of the circulation filtration system to complete the circulation process.

[0020] Preferably, the aeration holes on the aeration pipe are distributed in a spiral shape along the length of the aeration pipe.

[0021] Preferably, the pool body is provided with an auxiliary plate, and a guide rod that slides with the auxiliary plate is fixedly connected to the mounting frame, and a limiting plate is provided at the bottom of the guide rod.

[0022] By adopting the above technical solution, the mounting frame is modularly assembled, and the guide rod and auxiliary plate slide together to ensure a smooth and non-deviation-free lifting process.

[0023] Beneficial effects:

[0024] 1. Highly efficient and uniform oxygenation: Through the design of aeration holes with spiral distribution at the bottom, combined with the oxygen supply of the blower and the flow regulating valve, oxygen can be evenly delivered to the bottom of the water body, effectively solving the problem of insufficient dissolved oxygen at the bottom caused by traditional surface aeration, promoting the metabolism of shrimp, and reducing the incidence of diseases caused by hypoxia.

[0025] II. Dynamic Habitat Environment Optimization: The height-adjustable mounting frame, combined with the filter brush habitat, provides shrimp with a three-dimensional habitat and its height can be adjusted according to the size of the shrimp, preventing the accumulation of excrement caused by fixed habitat devices. The snap-on detachable structure further facilitates brush cleaning and replacement, reducing maintenance costs.

[0026] This application significantly improves the high-density aquaculture environment through the synergistic effect of bottom aeration and adjustable habitat devices, thereby increasing the survival rate and growth rate of shrimp. It is both economical and environmentally friendly, meeting the sustainable development needs of modern aquaculture. Attached Figure Description

[0040] Aeration system: Several aeration pipes 11 are evenly distributed at intervals along the bottom of the tank 1. Aeration holes 12 are spirally opened on the aeration pipes 11 (see embodiment 3 for details). The aeration pipes 11 are connected to the oxygen supply equipment (blower 14) through aeration branch pipes 13. A flow regulating valve 15 is installed on the branch pipe to accurately control the aeration volume.

[0041] Mounting frame and habitat: Mounting frame 2 consists of two first auxiliary plates 21 and several second auxiliary plates 22, which are fixedly connected by screws and nuts. Mounting frame 2 has a habitat 233 on the top, which includes multiple filter brushes 31, which are detachably connected by buckles 32 for easy cleaning and replacement.

[0042] Adjustment component: The adjustment component 4 includes an electric telescopic rod 41 (made of stainless steel and with a waterproof coating), one end of which is fixed to the bottom of the pool body 1, and the other end is connected to the first auxiliary plate 21. The telescopic rod 41 can drive the mounting frame 2 to rise and fall vertically along the side wall of the pool body 1 to adjust the water depth of the habitat 233. If it is necessary to clean the inside of the pool body 1, the habitat 233 can be raised outside the pool body 1 for thorough cleaning.

[0043] Technical benefits: Bottom aeration improves dissolved oxygen efficiency; the adjustable mounting frame accommodates shrimp at different growth stages; the filter brush provides a biofilm carrier and adsorbs impurities, increasing stocking density and survival rate, and facilitating pond cleaning.

[0044] Example 2, Funnel-shaped Pond Bottom and Circulation System: Based on Example 1, this example further optimizes the pond structure: The bottom of pond 1 is designed as a funnel-shaped structure sloping towards the center, with a suction port at the lowest point. The suction port is connected to an external circulation filtration system via a pipe, and a filter screen (not shown) is installed on the pipe to prevent shrimp from being discharged. The circulation filtration system can control the water flow rate by adjusting the power, achieving targeted collection of uneaten feed and feces from the pond bottom and water purification.

[0045] Technical benefits: The funnel-shaped structure accelerates the accumulation of uneaten feed and feces towards the center, facilitating regular sewage discharge; the circulating filtration system achieves water purification and resource recycling, reducing the frequency of water changes and lowering aquaculture costs.

[0046] Example 3, spiral aeration hole design, based on Example 1, this example improves the aeration pipe structure ( Figure 3 The aeration holes 12 on the aeration pipe 11 are spirally distributed along the length direction, and the spiral angle between adjacent aeration holes 12 is 60°-120°.

[0047] Technical effects: The spirally distributed aeration holes cause the rising paths of bubbles to intersect, enhancing water turbulence, expanding the dissolved oxygen coverage area, reducing local hypoxic areas, and improving aeration efficiency.

[0048] Example 4, guide rod limiting structure, based on Example 1, this example optimizes the lifting stability of the mounting frame. Figure 1 The bottom of the mounting bracket 2 is fixedly connected to the guide rod 17, which slides with the auxiliary plate 16 of the pool body 1. The bottom of the guide rod 17 is provided with a limiting plate 18.

[0049] Technical effect: The guide rod 17 and the auxiliary plate 16 form a sliding pair to limit the horizontal displacement of the mounting frame 2; the limiting plate 18 prevents the mounting frame 2 from descending excessively and ensures structural safety.

[0050] Summary of Implementation Methods: This utility model, through modular design, integrates an aeration system and a height-adjustable perching device, significantly improving dissolved oxygen efficiency, water quality stability, and management convenience in high-density shrimp farming. Each embodiment can be implemented individually or used in combination to achieve optimal farming results.
