Description

Technical Field

[0001] This utility model relates to the field of mandarin fish farming technology, and in particular to a water-pushing device for mandarin fish farming. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process of raising aquatic products from seedlings to finished products under artificial feeding and management. In a broader sense, it can also include the enhancement of aquatic resources. Aquaculture can be categorized into extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves releasing seedlings into small to medium-sized natural water bodies and raising aquatic products entirely based on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as fish farming in ponds, cage farming, and enclosure farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation, and feeding high-quality feed to conduct high-density farming in small bodies of water, thereby achieving high yields, such as high-density fish and shrimp farming in flowing water.

[0003] Some traditional fishpond aquaculture water-pushing devices cannot be installed in a fixed position; that is, neither the vertical depth nor the horizontal distance can be adjusted. A water-pushing device with a fixed depth may not effectively promote uniform water flow, leading to reduced water exchange efficiency and preventing the timely removal of harmful substances, potentially affecting water quality. Furthermore, the distance between the water-pushing part and the center of the fishpond cannot be adjusted. On the other hand, a water-pushing device with a fixed horizontal distance may reduce water exchange efficiency, and the fixed distance limits the effective coverage area of ​​the device in the pond, making it difficult to evenly distribute dissolved oxygen and maintain optimal water quality.

[0004] Some existing technologies use liftable floating water-pushing devices, which use propellers as the water-pushing device. The rotation of the propeller changes the horizontal position of the water-pushing device, and the lifting mechanism is used to adjust the vertical depth. However, the water-pushing position is constantly changing, which makes it impossible to change the water flow in a regular and continuous manner. This can easily lead to disordered water flow inside the water body, which is not conducive to daily aquaculture.

[0005] It is evident that existing water-pushing devices either have a fixed installation position that cannot be flexibly adjusted, or have an installation position that is too flexible to be fixed, thus failing to meet the requirements of both position adjustability and operational stability.

[0048] This utility model provides a water-pushing device for mandarin fish farming, which solves the technical problem that existing water-pushing devices cannot simultaneously achieve position adjustment and operational stability.

[0049] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0050] Please see Figures 1 to 8 The present invention provides a water-pushing device for mandarin fish farming, comprising a vertical moving mechanism 1, a mounting frame 2, a horizontal moving mechanism 3, and a water-pushing mechanism 4;

[0051] The moving part of the vertical moving mechanism 1 is connected and fixed to the mounting frame 2. The vertical moving mechanism 1 is used to fix it on the object to be installed. The horizontal moving mechanism 3 is installed on the mounting frame 2. The mounting frame 2 is slidably connected to the water pushing mechanism 4. The moving part of the horizontal moving mechanism 3 is connected and fixed to the water pushing mechanism 4.

[0052] In the operation of this embodiment, the vertical moving mechanism 1 is fixed on the object to be installed, and then the vertical moving mechanism 1 is activated to adjust the vertical position of the mounting frame 2. The horizontal moving mechanism 3 and the water pushing mechanism 4 on the mounting frame 2 will change with the change of the vertical position of the mounting frame 2, that is, the installation depth of the water pushing mechanism 4 is effectively adjusted. After the vertical position is adjusted, the horizontal moving mechanism 3 is activated to adjust the horizontal position of the water pushing mechanism 4, thereby realizing the change of the position of the water pushing mechanism 4 in the pool, so that the water pushing mechanism 4 is away from or close to the center of the fish pool.

[0053] The object to be installed that is connected and fixed to the vertical moving mechanism 1 can be the edge of the aquaculture pond, or a fixed pipe or fixed structure suspended on the aquaculture pond.

[0054] Compared to existing technologies, the advantages of this embodiment are as follows: First, the installation position can be flexibly adjusted. Compared to traditional water-pushing devices for fishpond aquaculture where the installation position cannot be adjusted, the vertical depth of the water-pushing mechanism 4 in this embodiment can be flexibly adjusted, and the horizontal distance of the water-pushing mechanism 4 can also be flexibly adjusted. This promotes uniform flow of the entire water body, improves water exchange efficiency, and promptly removes harmful substances from the water. It can significantly optimize water flow distribution, improve water quality management, and enhance water circulation efficiency and oxygen distribution, while meeting the needs of different aquaculture stages. Through this flexible adjustment, the energy efficiency of the equipment can be improved, its service life extended, and the healthy growth of fish promoted, bringing higher aquaculture benefits to farmers. Second, the installation position can be fixed. Compared to existing floating water-pushing devices, the water-pushing mechanism 4 in this embodiment can be adjusted in installation position or kept fixed after adjustment, avoiding the problem of the water-pushing position constantly changing, which prevents the water flow from being changed in a regular and continuous manner.

[0055] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, a feasible structure for the vertical moving mechanism 1 is further provided. The vertical moving mechanism 1 includes a connecting seat 10, a fixing sleeve 11, a screw 12, and a moving sleeve 13. The connecting seat 10 has a connecting through hole and is used to fix it to the object to be installed. The fixing sleeve 11 is connected and fixed to the connecting seat 10, forming an "L" shape. Both ends of the fixing sleeve 11 are open, and the fixing sleeve 11 is aligned with the connecting through hole. The axis of the fixing sleeve 11 is coaxial with the axis of the connecting through hole. The upper end of the screw 12 is engaged in the connecting through hole, and a snap-fit ​​block is fixed to the outside of the screw 12. The size of the snap-fit ​​block is larger than the size of the connecting through hole to achieve the engagement of the screw 12 in the connecting through hole. The lower end of the screw 12 passes through the connecting through hole and extends into the fixing sleeve. Inside the fixed sleeve 11, a handwheel 120 is provided at the end of the screw 12 away from the fixed sleeve 11; the movable sleeve 13 is connected and fixed to the mounting frame 2, the movable sleeve 13 extends into the fixed sleeve 11, the movable sleeve 13 is slidably connected to the fixed sleeve 11, the movable sleeve 13 is sleeved on the outside of the screw 12, the screw 12 is screwed to the movable sleeve 13, and the rotation of the screw 12 is used to move the movable sleeve 13 axially; in specific implementation, the user can fix the connecting seat 10 on the object to be installed to fix the vertical moving mechanism 1. When it is necessary to adjust the vertical position, the user turns the handwheel 120 to move the screw 12 in the movable sleeve 13, thereby driving the movable sleeve 13 to move up and down along the axis of the movable sleeve 13, thereby adjusting the vertical installation depth of the mounting frame 2 and the water pushing mechanism 4 on the mounting frame 2.

[0056] It should be noted that the vertical moving mechanism 1 can also be other linear moving mechanisms. However, other electric structures, such as ball screws, are prone to insufficient overload resistance. Therefore, the purely mechanical screw 12 adjustment method used in this embodiment has a significant advantage in overload resistance compared to other electric structures.

[0057] In one embodiment, such as Figure 1 As shown, to prevent the movable sleeve 13 from rotating with the screw 12, the fixed sleeve 11 is provided with a fixed guide groove 110; a fixed guide block 130 is fixedly connected to the outside of the movable sleeve 13, and the fixed guide block 130 is slidably installed in the fixed guide groove 110. In specific implementation, when the screw 12 rotates, the fixed guide block 130 located in the fixed guide groove 110 can restrict the rotation of the movable sleeve 13, so that the rotation of the screw 12 becomes the movement of the movable sleeve 13.

[0058] The fixed sleeve 11 is a regular polygon, while the movable sleeve 13 matches the shape of the fixed sleeve 11, so that when the screw 12 rotates, the movable sleeve 13 will not rotate with the screw 12 under the limitation of the fixed sleeve 11, thereby converting the rotation of the screw 12 into the axial movement of the movable sleeve 13.

[0059] In one embodiment, such as Figure 4As shown, to avoid the problem of long-term water accumulation in the vertical moving mechanism 1, the end of the moving sleeve 13 adjacent to the screw 12 is open to allow the screw 12 to pass through. The end of the moving sleeve 13 away from the screw 12 is provided with a drainage hole 131. That is, the drainage hole 131 is located at the bottom of the moving sleeve 13. One end of the drainage hole 131 is connected to the interior of the moving sleeve 13, and the other end of the drainage hole 131 extends out of the outer wall of the moving sleeve 13. In specific implementation, when the entire device is lifted out of the water, the water in the screw 12 and the moving sleeve 13 can be discharged through the drainage hole 131 at the bottom of the moving sleeve 13, which can prevent long-term water accumulation in the vertical moving mechanism 1 and prevent the screw 12 from being immersed in water for a long time, thus avoiding obstruction of rotation.

[0060] In one specific embodiment, such as Figure 7 and Figure 8 As shown, in order to make the movement of the water-pushing mechanism 4 more accurate, a feasible structure of the mounting frame 2 is further provided. The mounting frame 2 is provided with a moving guide rail 23, and a moving slider 24 is slidably mounted on the moving guide rail 23. The moving slider 24 is connected and fixed to the water-pushing mechanism 4. In specific implementation, when the horizontal moving mechanism 3 pushes the water-pushing mechanism 4 to move, the water-pushing mechanism 4 will drive the moving slider 24 to slide on the moving guide rail 23 to achieve guided movement and improve the stability of the water-pushing mechanism 4.

[0061] In one embodiment, such as Figure 7 As shown, a feasible structure for the mounting bracket 2 is further provided. The mounting bracket 2 includes a first frame 20, a second frame 21, and a third frame 22, which are connected sequentially to form a "U"-shaped placement space. A horizontal moving mechanism 3 is located within the placement space and is connected to the second frame 21. Both the first frame 20 and the third frame 22 are provided with mounting guide grooves 25, which are arranged parallel to the length direction of the first frame 20 and the third frame 22. A moving guide rail 23 is fixed inside the mounting guide groove 25. The two mounting guide grooves 25 are arranged on opposite sides of the horizontal moving mechanism 3, that is, the moving guide rail 23 is arranged on opposite sides of the horizontal moving mechanism 3. In specific implementation, the water pushing mechanism 4 is slidably mounted on the first frame 20 and the third frame 22. The horizontal moving mechanism 3 on the second frame 21 drives the water pushing mechanism 4 to move on the first frame 20 and the third frame 22, thereby adjusting the horizontal position of the water pushing mechanism 4.

[0062] In one specific embodiment, such as Figure 4 and Figure 7 As shown, a feasible structure for the horizontal moving mechanism 3 is further provided. The horizontal moving mechanism 3 is an electric telescopic rod. The motor of the electric telescopic rod is hidden inside the second frame 21. The rod body of the electric telescopic rod is connected and fixed to the water pushing mechanism 4, thereby realizing the horizontal position adjustment of the water pushing mechanism 4.

[0063] The output end of the electric telescopic rod is fixedly connected to the connecting piece 30. The electric telescopic rod can be a waterproof electric push rod of model MS2000A.

[0064] In one specific embodiment, such as Figures 1 to 3 As shown, a feasible structure for the water-pushing mechanism 4 is further provided. The water-pushing mechanism 4 includes a water-pushing base 40, a water-pushing motor 41, and a water-pushing propeller. The upper surface of the water-pushing base 40 is connected and fixed to the moving part of the horizontal moving mechanism 3, and the upper surface of the water-pushing base 40 is slidably connected to the mounting frame 2, that is, the water-pushing base 40 is connected and fixed to the slider on the mounting frame 2. The water-pushing motor 41 is fixed to the upper surface of the water-pushing base 40. The water-pushing propeller is connected and fixed to the output end of the water-pushing motor 41. In specific implementation, starting the water-pushing motor 41 enables the water-pushing propeller to start pushing water. Compared with some existing technologies, the water-pushing mechanism 4 in this embodiment is slidably mounted on the mounting frame 2. The installation position of the water-pushing mechanism 4 can be adjusted, and after the position of the water-pushing mechanism 4 is fixed, since the water-pushing mechanism 4 is fixed on the horizontal moving mechanism 3 and the vertical moving mechanism 1, its installation position remains fixed, thereby achieving stable water pushing by the water-pushing mechanism 4.

[0065] In one embodiment, a specific structure of a water-pushing base 40 is provided. The water-pushing base 40 is a hollow frame, and a connecting rod 400 is fixed in the middle of the hollow frame. The connecting rod 400 is used to connect the connecting piece 30 on the horizontal moving mechanism 3, thereby completing the connection between the water-pushing mechanism 4 and the horizontal moving mechanism 3.

[0066] In one embodiment, such as Figure 3 As shown, in order to protect the propeller, the propeller is covered with a propeller protection cover 43. The propeller protection cover 43 has multiple flow holes for water to pass through. The flow holes are evenly arranged on the propeller protection cover 43. In specific implementation, the flow holes of the propeller protection cover 43 can allow water to flow in and out normally. The presence of the propeller protection cover 43 can protect the propeller from being hit by farmed fish. That is, the flow holes allow water to pass through but fish cannot pass through, effectively protecting the propeller and the farmed fish.

[0067] In one embodiment, such as Figure 1 and Figure 3 As shown, in order to filter the water entering the propeller, the propeller mechanism 4 also includes a filter screen 44, which is connected to the propeller base 40. The filter screen 44 is located in the water inlet path of the propeller, i.e., as shown... Figure 1 As shown, the filter screen 44 is located on the opposite side of the propeller and is arranged near the propeller motor 41. This side is located on the water inlet path of the propeller. In practice, the filter screen 44 can filter farmed fish or garbage that enter the propeller.

[0068] In this embodiment, to facilitate cleaning of the filter screen 44, such as... Figure 5 and Figure 6 As shown, the filter screen 44 is also provided with a cleaning component 45; the cleaning component 45 includes at least two cleaning guide rails 450, at least two cleaning sliders 451, and a cleaning brush 452; the mounting frame 440 that accommodates the filter screen 44 has cleaning grooves on opposite sides along the height direction, and the cleaning guide rails 450 are fixed in the cleaning grooves, that is, the two cleaning guide rails 450 are arranged on opposite sides of the filter screen 44, and the cleaning sliders 451 are slidably installed on the cleaning guide rails 450. The sliders 451 are all connected and fixed to the cleaning brushes 452. The cleaning brushes 452 abut against the filter surface of the filter screen 44. That is, the cleaning brushes 452 are horizontally mounted on the filter screen 44, and the bristles of the cleaning brushes 452 abut against the surface of the filter screen 44. In practice, the cleaning brushes 452 can be pulled along the length of the cleaning guide rail 450 to complete the cleaning of the surface of the filter screen 44. There is no need for additional disassembly or special machine stop cleaning, making the cleaning of the filter screen 44 convenient.

[0069] In addition, such as Figure 6 As shown, to facilitate the disassembly of the filter screen 44, a limiting sleeve 441 is provided at the bottom of the filter screen 44. The upper end of the limiting sleeve 441 is normally open, and the inner walls on both sides of the limiting sleeve 441 are provided with mounting grooves 4400 for sliding installation of the filter screen 44. The two mounting grooves 4400 are arranged opposite to each other. In specific implementation, the mounting frame 440 with the filter screen 44 can be inserted and pulled out from the mounting groove 4400 and then placed into other water areas. The cleaning brush 452 slides back and forth along the length of the cleaning guide rail 450 to clean the garbage on the surface of the filter screen 44, so that the filter screen 44 can be reused. The designed filter screen 44 is easy to disassemble and clean, can be reused, and reduces the cost of use.

[0070] In one specific embodiment, such as Figure 3 As shown, in order to achieve the aeration function, the water-pushing device for mandarin fish farming also includes an aeration mechanism 5; the aeration mechanism 5 includes an air inlet pipe 50 and multiple aeration pipes 51; the air inlet pipe 50 is connected to the multiple aeration pipes 51; the multiple aeration pipes 51 are all fixed on the water-pushing base 40 of the water-pushing mechanism 4, that is, multiple aeration pipes 51 are fixed on the left side of the upper surface of the water-pushing base 40. In specific implementation, the air inlet pipe 50 is connected to an external air intake device to introduce gas into the aeration pipes 51. The gas flows outward through the aeration pipes 51 to form oxygenated bubbles, which increases the dissolved oxygen in the water, improves the water quality, and provides a better living environment for fish. At the same time, aeration can also promote the circulation and flow of water, which helps to reduce harmful substances in the water.

[0071] As can be seen from the above, this solution has a basic structure and principle. The following section will provide a complete explanation of the working process.

[0072] In use, the device is first fixed to the edge of the fishpond using bolts and the connecting seat 10 of the vertical moving mechanism 1. Then, by turning the handwheel 120, the screw 12 is driven to rotate, causing the moving sleeve 13 to move upwards or downwards under threaded engagement, thus adjusting the height of the mounting bracket 2. This, in turn, causes the water-pushing mechanism 4 to be at different depths in the water. Furthermore, the extension of the output end of the horizontal moving mechanism 3 pushes the water-pushing base 40 of the water-pushing mechanism 4 to slide away from the moving sleeve 13, allowing the water-pushing mechanism 4 to approach the center of the fishpond. Next, the water-pushing motor 41 drives the water-pushing propeller to rotate and push water into the fishpond. The water flow causes eddies to form in the fishpond. Due to centrifugal force, the water tends to be thrown outwards, resulting in a water surface that is lower in the middle and higher around the edges. During this process, fish excrement and feed deposits will accumulate at the bottom center of the fishpond with the water flow. The excrement and feed deposits accumulated at the bottom center of the fishpond can be discharged through the funnel at the bottom of the fishpond. During the water rotation, some loose excrement and feed deposits can be blocked by the filter screen 44 to prevent these deposits from being drawn into the propeller during the rotation, which would cause the water to become turbid.
