Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a bacteriophage spraying device for aquaculture farms. Background Technology

[0002] As aquaculture transforms towards intensive, efficient, and ecological practices, traditional pond aquaculture, with its low land utilization, high water consumption, difficulty in disease control, and low yield, can no longer meet the core demands of modern aquaculture for increased profits. Against this backdrop, the land-based circular pond high-density recirculating aquaculture system has emerged. This model utilizes standardized circular ponds built on land, equipped with closed-loop water circulation systems, centralized wastewater treatment facilities, and intelligent monitoring and control equipment. The stocking density can be many times higher than in traditional ponds, significantly increasing yield per unit area. Land-based circular pond high-density recirculating aquaculture is highly adaptable, encompassing not only common fish and shrimp, but also crustaceans (such as mud crabs and swimming crabs), amphibians (such as Chinese soft-shelled turtles and bullfrogs), and specialty aquatic products (such as eels and yellow catfish), further expanding the profit margins for aquaculture operators.

[0003] However, high-density enclosed environments also present significant challenges for disease control: pathogens in aquaculture water can easily multiply rapidly due to excessive population density. Bacteriophages, as viruses that specifically lyse bacteria, have become an ideal choice for disease control in recirculating aquaculture systems. By atomizing the medication through a spray device, it can be evenly diffused into the aquaculture water, inhibiting pathogens in the water, reducing the intake of pathogens by aquaculture organisms, and cutting off the disease transmission chain.

[0004] To ensure uniform distribution of bacteriophages in a circular tank, the nozzles of the spray device are typically installed above the center of the land-based circular tank via a support structure, utilizing a central diffusion path to cover the entire tank with bacteriophage droplets. However, this installation method has significant drawbacks: the nozzles are located directly above the center of the tank, and circular tanks, being high-density aquaculture environments, are not only filled to near their upper limit but also have densely distributed cultured organisms. When the nozzles need to be disassembled for maintenance or replacement, the tank size limits access to the central nozzles, necessitating the removal of the supporting structure. These supporting structures are often metal brackets spanning the tank or multi-layered fixed frames on a central column. To ensure load-bearing stability, they are typically connected by multiple sets of bolts and clips, and some are even welded. Disassembly requires cleaning rusted parts before loosening the connections one by one, making the process cumbersome and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a bacteriophage spraying device for aquaculture farms, which allows the spray nozzle to be easily rotated from the center of the main body of the land-based water tank to the outside of the main body. The replacement and maintenance of the spray nozzle can be easily completed without removing the support mechanism. It can also be adapted to land-based water tanks of different sizes through multi-dimensional adjustment methods such as horizontal extension, height adjustment, and horizontal rotation fine adjustment, ensuring that the spray nozzle is always stably located in the optimal spraying position in the center of the main body of the land-based water tank, ensuring that the bacteriophage droplets evenly cover the entire water body, and taking into account both ease of operation and precision of application.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A bacteriophage spraying device for aquaculture farm includes a land-based water tank body and a liquid supply power component. The output end of the liquid supply power component is connected to a spray nozzle via a soft water pipe. The spray nozzle is mounted on the land-based water tank body via a support mechanism. The support mechanism includes a mounting base. The bottom of the mounting base has a slot adapted to the land-based water tank body. The mounting base is inserted into the land-based water tank body via the slot. Mounting plates are provided on both sides of the bottom of the mounting base, and mounting holes are provided on the mounting plates.

[0008] The mounting base has a rotating groove inside, and a rotating column is installed inside the rotating groove. The rotating column and the rotating groove are interference-fitted. A connecting column that penetrates the interior of the mounting base is fixed to the top of the rotating column, and the connecting column is rotatably connected to the mounting base. A vertical support column with the same diameter as the connecting column is installed to the top of the connecting column. An extension rod is slidably connected to the inner side of the vertical support column. A transverse support column is fixed to the top of the extension rod. An extension rod is slidably connected to the inner side of the transverse support column. The spray nozzle is detachably fixed to the extension rod. A snap-fit ​​plug is installed at the end of the extension rod near the spray nozzle. A snap-fit ​​socket adapted to the snap-fit ​​plug is installed on the spray nozzle. The extension rod and the spray nozzle are snapped together by the snap-fit ​​plug and the snap-fit ​​socket.

[0009] Both the vertical support column and the horizontal support column are provided with first positioning bolts. When the two first positioning bolts are threadedly connected to the horizontal support column and the vertical support column respectively, the two first positioning bolts abut against the extension rod and the extension rod respectively.

[0010] The connecting column and the vertical support column are connected by a connector, which includes a positioning tube and a metal shaping hose. The positioning tube is sleeved on the outside of the vertical support column and the connecting column, and the top and bottom of the metal shaping hose are fixedly connected to the vertical support column and the connecting column, respectively.

[0011] The technical effects achieved by this utility model are as follows:

[0012] This invention allows the spray nozzle to be easily rotated from the center of the main body of the land-based water tank to the outside of the main body. The replacement and maintenance of the spray nozzle can be easily completed without removing the support mechanism. It can also be adapted to land-based water tanks of different sizes through multi-dimensional adjustment methods such as horizontal extension, height adjustment and horizontal rotation fine adjustment. It ensures that the spray nozzle is always stably in the optimal spray position in the center of the main body of the land-based water tank, ensuring that the bacteriophage droplets evenly cover the entire water body, and taking into account both ease of operation and precision of application.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-8 As shown, a bacteriophage spraying device for aquaculture farm includes a land-based water tank body 1 and a liquid supply power component 2, wherein the output end of the liquid supply power component 2 is connected to a spray nozzle 3 through a soft water pipe, and the spray nozzle 3 is installed above the land-based water tank body 1 through a support mechanism.

[0025] Both the liquid supply power assembly 2 and the spray nozzle 3 are existing mature technologies. The liquid supply power assembly 2 consists of a protective shell, a power pump, and a liquid storage tank, with the power pump and liquid storage tank installed inside the protective shell. During operation, the power pump draws bacteriophage solution from the liquid storage tank, pressurizes the solution, and delivers it to the spray nozzle 3 through a soft water pipe. The spray nozzle 3 atomizes the solution. Since the spray nozzle 3 is installed above the land-based water tank body 1 through a support mechanism, the atomized solution mainly falls into the water body inside the land-based water tank body 1, achieving water disinfection and killing harmful bacteria. At the same time, some droplets diffuse to the periphery of the land-based water tank body 1, helping to reduce suspended bacteria in the air.

[0026] In this embodiment, the liquid supply power component 2 and the spray nozzle 3 will not be described in detail. The core of this technical solution lies in the specific structure of the support mechanism.

[0027] The support mechanism includes a mounting base 4, which supports the upper components of the support mechanism. The mounting base 4 adopts a dual design to improve flexibility, as detailed below:

[0028] See attached document Figure 1 , 2 and attached Figure 3 The mounting base 4 has a slot at its bottom that precisely matches the edge contour and size of the land-based water tank body 1. During installation, simply align the slot with the edge of the land-based water tank body 1 and push it in horizontally to complete the initial positioning and fixation. This plug-in method requires no tools and can be quickly operated by a single person. It not only achieves a tight connection between the mounting base 4 and the land-based water tank body 1, but also effectively limits the lateral displacement of the mounting base 4 through the fit between the slot and the edge of the land-based water tank body 1.

[0029] At the same time, there is no need to drill holes or perform other processing on the main body of the land-based water tank 1, thus avoiding damage to the main body of the land-based water tank 1. It is especially suitable for scenarios where the edges of the main body of the land-based water tank 1 are regular, such as concrete or metal pool edges, balancing installation efficiency and protection of the carrier.

[0030] To further enhance the stability of the connection between the mounting base 4 and the land-based water tank body 1, a second positioning bolt 18 is also provided on the mounting base 4. The mounting base 4 has a threaded hole that matches the second positioning bolt 18, and the axis of the threaded hole points towards the outer wall of the land-based water tank body 1. After the mounting base 4 is initially inserted into the edge of the land-based water tank body 1 through the bottom slot, the operator can rotate the second positioning bolt 18 clockwise. The second positioning bolt 18 will then tightly abut against the outer wall of the land-based water tank body 1, thus positioning the mounting base 4.

[0031] In addition, mounting plates 19 are symmetrically arranged on both sides of the bottom of the mounting base 4. The mounting plates 19 are provided with mounting holes for standard fastening bolts, further expanding the fixing scenarios. If the edge of the land-based water tank body 1 is not suitable for insertion, such as if the pool wall is too thin or the edge is irregular, the mounting base 4 can be fixed to the ground, steel frame platform or other carriers by fastening bolts through the mounting holes. For example, expansion bolts can be used to fasten it to the cement ground. The mounting plates 19 can also be adapted to other fixing surfaces such as walls and mounting brackets, so that the installation of the mounting base 4 is no longer limited to the land-based water tank body 1 itself.

[0032] With its combination design of quick-connect slots and multi-carrier fixation of mounting plate 19, mounting base 4 can not only achieve convenient docking with the main body 1 of land-based water tank, but also flexibly adapt to other fixed scenarios, providing multiple options for the stable installation of the support mechanism.

[0033] The mounting base 4 has a rotating groove inside, and a rotating column 6 is installed inside the rotating groove. The rotating column 6 and the rotating groove are interference-fitted. A connecting column 5 that penetrates the interior of the mounting base 4 is fixed at the top of the rotating column 6, and the connecting column 5 is rotatably connected to the mounting base 4. A vertical support column 7 with the same diameter as the connecting column 5 is installed at the top of the connecting column 5, and an extension rod 8 is provided inside the vertical support column 7.

[0034] A first guide groove adapted to the extension rod 8 is provided on the inner side of the vertical support column 7. The extension rod 8 is located inside the first guide groove. The extension rod 8 can be inserted into the inner side of the vertical support column 7 through the first guide groove and slide freely along the axial direction of the vertical support column 7.

[0035] The top of the extension rod 8 is fixed with a transversely arranged transverse support column 9, and the extension rod 10 is installed inside the transverse support column 9;

[0036] A second guide groove adapted to the extension rod 10 is provided on the inner side of the transverse support column 9. The extension rod 10 is located inside the second guide groove. The extension rod 10 can be inserted into the inner side of the extension rod 10 through the second guide groove and slide freely along the axial direction of the extension rod 10.

[0037] See attached document Figure 1 and attached Figure 8The spray nozzle 3 is mounted on the extension rod 10. To improve the ease of disassembly and installation of the spray nozzle 3, the spray nozzle 3 and the extension rod 10 are connected by a snap-fit ​​structure for detachable fixation. A snap-fit ​​plug 11 is installed at one end of the extension rod 10 near the spray nozzle 3, and the spray nozzle 3 is equipped with a snap-fit ​​socket 22 that is compatible with the snap-fit ​​plug 11. The specific design and operation process are as follows:

[0038] The snap-fit ​​plug 11 is made of a material with a certain deformation capability, such as engineering plastic or elastic metal. The bottom of the snap-fit ​​plug 11 is provided with a locking block. The inner contour of the snap-fit ​​socket 22 is precisely matched with the locking block of the snap-fit ​​plug 11 to form a mechanical structure that can be quickly engaged.

[0039] Installation and fixing are extremely simple: just align the snap-fit ​​socket 22 on the spray nozzle 3 with the snap-fit ​​plug 11 at the end of the extension rod 10, and gently push the spray nozzle 3 axially. Once the snap-fit ​​plug 11 is fully inserted into the snap-fit ​​socket 22, the snap-fit ​​plug 11 and the inside of the snap-fit ​​socket 22 will tightly engage to form a secure lock. The process requires no tools and can be completed by one person with one hand. The locked structure can stably resist the water flow pressure and equipment vibration during spraying, ensuring that the spray nozzle 3 will not accidentally fall off during operation and guaranteeing the continuity of the spraying process.

[0040] During disassembly and separation: pull the spray nozzle 3 to disengage the snap-fit ​​plug 11 from the inside of the snap-fit ​​socket 22, and then pull the spray nozzle 3 axially to easily separate it.

[0041] Both the vertical support column 7 and the horizontal support column 9 are provided with first positioning bolts 12, and the two first positioning bolts 12 are threadedly connected to the vertical support column 7 and the horizontal support column 9 respectively.

[0042] When the first positioning bolt 12 on the vertical support column 7 is tightened, the end of the first positioning bolt 12 on the vertical support column 7 will be tightly abutted against the outer wall of the extension rod 8.

[0043] When the first positioning bolt 12 on the transverse support column 9 is tightened, the end of the first positioning bolt 12 on the transverse support column 9 will abut tightly against the outer wall of the extension rod 10.

[0044] In use: First, install the mounting base 4 on the main body 1 of the land-based water tank or fix it in the designated position. Then, adjust the position of the spray nozzle 3 according to the size of the main body 1 of the land-based water tank. The specific adjustment process is as follows:

[0045] First, loosen the two first positioning bolts 12 to release them from the tight position against the extension rod 8 and the extension rod 10. Then, adjust the horizontal distance according to the diameter of the land-based water tank body 1. Pull or push the extension rod 10 along the axial direction of the transverse support column 9. If the diameter of the land-based water tank body 1 is large, pull the extension rod 10 outward to extend it from inside the transverse support column 9, thus extending the horizontal distance between the spray nozzle 3 and the edge of the land-based water tank body 1. If the diameter of the land-based water tank body 1 is small, push the extension rod 10 inward to retract it into the transverse support column 9, thus shortening the horizontal distance and ensuring that the horizontal projection of the spray nozzle 3 is initially aligned with the center of the land-based water tank body 1.

[0046] Then adjust the height by pulling or pushing the extension rod 8 along the axis of the vertical support column 7. If the diameter of the main body 1 of the land-based water tank is large and the water level is high, pull the extension rod 8 upward to extend it out of the vertical support column 7, raising the height of the spray nozzle 3 to ensure that the droplets have enough space to spread and cover the entire water surface. If the diameter of the main body 1 of the land-based water tank is small and the water level is low, push the extension rod 8 downward to retract it into the vertical support column 7, lowering the height of the spray nozzle 3 to prevent the droplets from spreading excessively to the outside of the main body 1 of the land-based water tank.

[0047] If the spray nozzle 3 is not aligned with the center of the land-based water tank body 1 after horizontal and height adjustments, the vertical support column 7 or the horizontal support column 9 can be manually pushed to rotate the connecting column 5 and the rotating column 6 within the rotating groove of the mounting base 4. This causes the spray nozzle 3 to rotate slightly around the central axis of the mounting base 4 until the spray nozzle 3 is aligned with the center of the land-based water tank body 1. At this point, the interference fit between the rotating column 6 and the rotating groove will generate a preload, causing the inner walls of both to fit tightly together. The resulting static friction is sufficient to resist external forces during the spraying process, such as the weight of the spray nozzle 3 and the reaction force of the droplets. This ensures that the connecting column 5, the vertical support column 7, the extension rod 8, the horizontal support column 9, the extension rod 10, and the spray nozzle 3 remain stably in the adjusted position without any unexpected rotation.

[0048] Finally, after confirming that the position of the spray nozzle 3 is accurate, tighten the first positioning bolts 12 on the vertical support column 7 and the horizontal support column 9 respectively, so that the first positioning bolts 12 on the vertical support column 7 are tightly pressed against the outer wall of the extension rod 8 and the first positioning bolts 12 on the horizontal support column 9 are tightly pressed against the outer wall of the extension rod 10, locking the position of the extension rod 8 and the extension rod 10, ensuring that the spray nozzle 3 will not be displaced due to water flow impact or equipment vibration during the spraying process.

[0049] When it is necessary to disassemble the spray nozzle 3 for replacement or maintenance, the operator only needs to apply a horizontal rotational force to the vertical support column 7 or the horizontal support column 9. This force is transmitted to the connecting column 5 through the vertical support column 7. Since the connecting column 5 is fixedly connected to the rotating column 6, the rotating column 6 will be subjected to force synchronously with the connecting column 5 and will rotate relative to it in the rotating groove of the mounting base 4. As the connecting column 5 rotates, the vertical support column 7, extension rod 8, horizontal support column 9, and extension rod 10 connected to its top will rotate synchronously around the central axis of the mounting base 4. Since the spray nozzle 3 is fixed on the extension rod 10, it will gradually deviate from the initial position above the main body of the land-based water tank 1 as the entire support mechanism rotates.

[0050] Continue rotating until the spray nozzle 3 is completely removed from the water coverage area of ​​the land-based pool body 1, that is, until it reaches the outside of the land-based pool body 1, such as the side above the edge of the land-based pool body 1, then stop applying force: at this time, the interference fit between the rotating column 6 and the rotating groove will provide sufficient friction again, so that the connecting column 5 and the upper part are kept in the current position, and the spray nozzle 3 is prevented from accidentally rotating back to the top of the land-based pool body 1 during the disassembly process.

[0051] Finally, the spray nozzle 3 is stably placed on the outside of the main body 1 of the land-based water tank. Operators can easily disassemble and separate the spray nozzle 3 from the extension rod 10 without water interference or obstruction from the aquaculture environment, and complete the replacement operation of the spray nozzle 3.

[0052] In summary, this invention allows the spray nozzle 3 to be easily rotated from the center of the land-based water tank body 1 to the outside of the body 1. The replacement and maintenance of the spray nozzle 3 can be easily completed without removing the support mechanism. Furthermore, through multi-dimensional adjustment methods such as horizontal extension, height adjustment, and horizontal rotation fine adjustment, it can be adapted to land-based water tank bodies 1 of different sizes, ensuring that the spray nozzle 3 is always stably positioned in the optimal spraying position in the center of the land-based water tank body 1, ensuring that the bacteriophage droplets evenly cover the entire water body, and taking into account both ease of operation and precision of application.

[0053] In addition, the multi-dimensional adjustment function of this device can be adapted to breeding pens of different sizes, such as fattening pig pens and chicken coops. The nozzles can be adjusted by rotation and extension to accurately cover the breeding area, and can be quickly moved out of the breeding area during disassembly and maintenance to avoid disturbing livestock and poultry.

[0054] See attached document Figure 1 , 2 and attached Figure 4To further improve the ease of installation and disassembly of the spray nozzle 3, a connecting column 5 and a vertical support column 7 are connected by a connector. The connector includes a positioning tube 17 and a metal shaping hose 16. The top and bottom of the metal shaping hose 16 are fixedly connected to the bottom of the vertical support column 7 and the top of the connecting column 5, respectively. The positioning tube 17 is sleeved on the outside of the metal shaping hose 16. The positioning tube 17 can slide up and down along the outer wall of the vertical support column 7 and the connecting column 5.

[0055] In use, pull the positioning tube 17 upward along the outside of the vertical support column 7. During the upward pull, the positioning tube 17 gradually moves away from the connecting column 5, releasing the constraint on the metal shaping hose 16 and allowing the metal shaping hose 16 to be in a freely deformable state. At this time, by turning the rotating column 6 or applying force outward to the vertical support column 7, the metal shaping hose 16 bends, and simultaneously drives the vertical support column 7 and the extension rod 8, the horizontal support column 9, the extension rod 10, and the spray nozzle 3 to tilt as a whole. The bending of the metal shaping hose 16 causes the spatial position of the spray nozzle 3 to shift to the operator's side, and the height of the spray nozzle 3 is reduced. The operator can easily reach the spray nozzle 3 without tiptoeing, climbing, or using auxiliary tools, which greatly simplifies the snap-fit ​​fixing during installation and the separation operation during disassembly.

[0056] After the spray nozzle 3 is installed or maintained, first reverse the vertical support column 7 or rotate the column 6 to gradually return the metal shaping hose 16 to its initial upright state. Then slide the positioning tube 17 down along the outside of the vertical support column 7 to reset it. At this time, the bottom of the positioning tube 17 re-wraps the connection area between the connecting column 5 and the bottom of the vertical support column 7. The outside of the metal shaping hose 16 is wrapped by the positioning tube 17. The positioning tube 17 restricts the deformation of the metal shaping hose 16 and fixes the verticality of the vertical support column 7, so that the vertical support column 7 and the components above it will not tilt unexpectedly due to vibration, wind or the weight of the spray nozzle 3 during the spraying process, thus ensuring the stability of the spray direction of the spray nozzle 3.

[0057] The flexible design of the metal shaped hose 16 allows for a flexible reduction in the operating height of the spray nozzle 3, solving the inconvenience of high-position installation and disassembly; the rigid wrapping of the positioning tube 17 achieves structural locking, ensuring stability during operation.

[0058] See attached document Figure 1 , 2 4, 5 and appendix Figure 6To prevent the rotating column 6 from shifting position during operation and to improve the stability of rotational positioning, an annular elastic pad 21 is fixed on the outside of the rotating column 6. A positioning column 13 aligned with the annular elastic pad 21 is slidably connected inside the mounting base 4. The end of the positioning column 13 away from the annular elastic pad 21 extends through the interior of the mounting base 4. A circular plate 14 is fixed to the end of the positioning column 13 away from the annular elastic pad 21. A spring 15 is fixed to the side of the circular plate 14 near the mounting base 4 and located outside the positioning column 13. The end of the spring 15 away from the circular plate 14 is fixedly connected to the mounting base 4. In the initial state, the positioning column 13 abuts against the annular elastic pad 21.

[0059] When it is necessary to rotate the connecting column 5 to adjust the circumferential direction of the spray nozzle 3, the operator pulls the circular plate 14 outward. The circular plate 14 drives the positioning column 13 to slide away from the connecting column 5, while compressing the spring 15, causing the positioning column 13 to disengage from the annular elastic pad 21. At this time, the rotation constraint of the connecting column 5 is released, and it can rotate freely with the cooperation of the rotating column 6 and the rotating groove of the mounting base 4 until the spray nozzle 3 is adjusted to the target position. Then, the circular plate 14 is released, the elastic force of the spring 15 is released, and the circular plate 14 and the positioning column 13 are reset. The positioning column 13 is once again tightly abutted against the annular elastic pad 21. The position of the connecting column 5 is re-locked by the friction between the positioning column 13 and the annular elastic pad 21. The friction between the positioning column 13 and the annular elastic pad 21, together with the interference fit between the rotating column 6 and the rotating groove, forms a double constraint, which greatly improves the stability of the rotation positioning of the connecting column 5, further reduces the positional deviation of the spray nozzle 3, and ensures that it is always accurately aligned with the preset spray area.

[0060] See attached document Figure 7 In addition, multiple protrusions are provided at one end of the positioning post 13 near the annular elastic pad 21. The protrusions are conical. When the positioning post 13 abuts against the annular elastic pad 21, the multiple protrusions at the end of the positioning post 13 can be slightly embedded in the surface of the annular elastic pad 21. At this time, the contact between the protrusion and the annular elastic pad 21 is not a planar friction of a smooth surface, but rather the protrusion increases the local contact pressure, which significantly improves the friction between the protrusion and the annular elastic pad 21, thereby more stably restricting the non-human rotation of the connecting post 5.

[0061] See attached document Figure 1 In order to effectively constrain the soft water pipe connecting the liquid supply power component 2 and the spray nozzle 3 and prevent the soft water pipe from shaking or getting tangled, brackets 20 are provided on the outside of both the horizontal support column 9 and the vertical support column 7. The brackets 20 on the outside of the horizontal support column 9 are set horizontally, and the brackets 20 on the outside of the vertical support column 7 are set vertically.

[0062] The bracket 20 consists of a support rod and a positioning wheel. The positioning wheel is used to support and constrain the soft water pipe connecting the liquid supply power assembly 2 and the spray nozzle 3. The two support rods of the two brackets 20 are fixedly connected to the horizontal support column 9 and the vertical support column 7, respectively.

[0063] In use, the two supports position 20 pairs of soft water pipes, preventing the soft water pipes from shifting laterally to the water body side of the land-based water tank body 1 and from hanging down. Even if the water pipes are slightly loose, they will not touch the water body.

[0064] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
