Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a green and ecological freshwater aquaculture equipment. Background Technology

[0002] With the rapid development of aquaculture, intensive and high-density farming models have become mainstream. Under this model, effective environmental control of the aquaculture water is crucial to ensure the healthy growth and survival rate of aquatic products. Maintaining sufficient dissolved oxygen levels in the water and timely removal of floating pollutants such as residual feed and excrement are two of the most basic management aspects.

[0003] To achieve the aforementioned management objectives, existing aquaculture farms typically employ separate automated equipment. For example, aerators or aeration devices are used to oxygenate the water, while skimmers or automatic cleaning devices are used to collect floating pollutants. While these devices meet the basic requirements in their individual functions, they are usually independent systems, each requiring its own motor as a power source.

[0004] This design approach, where each functional unit relies on an independent power source, leads to a series of drawbacks. First, the parallel use of multiple motors results in high overall energy consumption for the entire aquaculture system, contradicting the modern agricultural development philosophy of pursuing green and energy-saving practices. Second, multiple independent devices increase the overall complexity of the system, not only occupying more physical space but also making installation, wiring, and subsequent maintenance more cumbersome, increasing operating costs and the risk of failure. Therefore, how to simplify the equipment structure while ensuring effective aeration and cleaning has become a pressing technical problem to be solved in the field of aquaculture equipment.

[0005] Therefore, this utility model proposes a green and ecological freshwater aquaculture equipment to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a green ecological freshwater aquaculture equipment, which aims to improve the problem that the existing mechanisms used for oxygenation and water cleaning are usually driven by independent power sources, resulting in complex overall equipment structure and high energy consumption.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a green ecological freshwater aquaculture equipment, comprising: an aquaculture tank, a power mechanism and an aeration mechanism disposed outside the aquaculture tank, and a cleaning mechanism disposed inside the aquaculture tank; the power mechanism includes a motor, a first rotating shaft, a second rotating shaft, a gear, and a second pulley fixed on the first rotating shaft, the motor driving and connecting the second rotating shaft, the second rotating shaft being connected to the first rotating shaft through the gear, thereby forming an integrated power system with a single motor as the power source and two transmission paths, a cam being fixedly connected to the second rotating shaft; the aeration mechanism includes an air cylinder, a pusher block slidably disposed inside the air cylinder, and an arc-shaped baffle, the contour of the cam abutting against and driving the arc-shaped baffle to reciprocate, and then the arc-shaped baffle linking the pusher block to slide inside the air cylinder; the cleaning mechanism includes a threaded rod, a first pulley fixed on the threaded rod, and a scraper threadedly engaged with the threaded rod, the first pulley and the second pulley being connected by a belt drive, realizing the synchronous drive of the aeration mechanism and the cleaning mechanism by a single power mechanism.

[0008] Preferably, the cleaning mechanism further includes a limiting post, and the scraper is slidably engaged with the limiting post to limit the scraper to move linearly along the axial direction of the threaded rod.

[0009] Preferably, the oxygenation mechanism further includes a connecting column, which is fixedly connected between the arc-shaped baffle and the push block.

[0010] Preferably, the oxygenation mechanism further includes a spring, which is sleeved on the outer periphery of the connecting column, and the two ends of the spring abut against the push block and the arc-shaped baffle, respectively.

[0011] Preferably, the cylinder wall is provided with an oxygen inlet and an oxygen outlet.

[0012] Preferably, it also includes a ventilation assembly for covering the opening of the aquaculture tank, the ventilation assembly including a ventilation plate and a rotating column rotatably connected to the ventilation plate.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting an integrated power mechanism, uses a single motor to drive the oxygenation mechanism and the cleaning mechanism in conjunction with the transmission components, solves the problem that the oxygenation and cleaning functions in the prior art are usually driven by separate power sources, resulting in complex equipment structure and high energy consumption.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5 This utility model provides an embodiment of a green ecological freshwater aquaculture equipment, including an aquaculture tank 1. The tank 1 has a power mechanism 7 and an aeration mechanism 6 on its exterior, and a cleaning mechanism 5 inside. The power mechanism 7 serves as the sole power source for the entire system and includes a motor 704, a first rotating shaft 702, a second rotating shaft 706, a gear 703, and a second pulley 701 fixedly connected to the first rotating shaft 702. Specifically, the motor 704 drives the second rotating shaft 706 to rotate, and the second rotating shaft 706 is connected to the first rotating shaft 702 via the gear 703. This achieves a single power source (motor 704) and divides the power into two transmission paths. The first transmission path drives the aeration mechanism. 6. A cam 705 is fixedly connected to the second rotating shaft 706. When the second rotating shaft 706 rotates, the contour of the cam 705 abuts against and drives the arc-shaped baffle 607 in the oxygenation mechanism 6 to reciprocate. The oxygenation mechanism 6 includes an air cylinder 601, a push block 604 slidably disposed in the air cylinder 601, and an arc-shaped baffle 607. The arc-shaped baffle 607 moves in conjunction with the push block 604 to slide back and forth in the air cylinder 601. The second transmission path is used to drive the cleaning mechanism 5. The cleaning mechanism 5 includes a threaded rod 501, a first pulley 504 fixed on the threaded rod 501, and a scraper 503 threadedly engaged with the threaded rod 501. The first pulley 504 is connected to the second pulley 701 in the power mechanism 7 via a belt, thereby driving the threaded rod 501 to rotate. The oxygenation mechanism 6 includes an air cylinder 601, a pusher block 604, an arc-shaped baffle 607, a connecting column 605, and a spring 606. The pusher block 604 is slidably disposed in the inner cavity of the air cylinder 601. The cylinder wall of the air cylinder 601 has an oxygen inlet 602 and an oxygen outlet 603. One end of the connecting column 605 is fixedly connected to the arc-shaped baffle 607, and the other end of the connecting column 605 is fixedly connected to the pusher block 604. The spring 606 is sleeved on the outer periphery of the connecting column 605, and both ends of the spring 606 abut against the pusher block 604 and the arc-shaped baffle 607, respectively. When the power mechanism 7 is working, the cam 7... As the second rotating shaft 706 rotates, the protruding contour of the cam 705 periodically impacts and pushes the arc-shaped baffle 607. The arc-shaped baffle 607 drives the pusher 604 to slide in the air cylinder 601 toward the oxygen outlet 603 through the connecting column 605, thus forcing the gas in the air cylinder 601 into the breeding tank 1 from the oxygen outlet 603. When the cam 705 rotates until its contour no longer abuts the arc-shaped baffle 607, the pusher 604 is pulled back to the initial position under the elastic force of the spring 606. At this time, the external gas enters the air cylinder 601 through the oxygen inlet 602, completing one cycle. The cleaning mechanism 5 includes a threaded rod 501, a scraper 503, a limiting post 502, and a first pulley 504. When the first rotating shaft 702 rotates, the threaded rod 501 is driven to rotate through the transmission of the second pulley 701, the belt, and the first pulley 504. The scraper 503 is threaded onto the threaded rod 501, and simultaneously slidably engaged with the limiting post 502. The presence of the limiting post 502 restricts the rotation of the scraper 503. Therefore, when the threaded rod 501 rotates, the scraper 503, which cannot rotate with it, can only reciprocate linearly along the axial direction of the threaded rod 501, thereby cleaning the floating debris on the water surface inside the aquaculture tank 1. To limit the linear motion of the scraper 503, the cleaning mechanism 5 also includes a limiting post 502, with the scraper 503 slidably fitted to the limiting post 502. This structure prevents the scraper 503 from rotating when moving along the threaded rod 501. To enable power transmission within the aeration mechanism 6, the aeration mechanism 6 also includes a connecting post 605, one end of which is fixedly connected to the arc-shaped baffle 607, and the other end is fixedly connected to the push block 604. More specifically, to enable the automatic reset of the push block 604, the aeration mechanism 6 also includes a spring 606, which is sleeved on the outer periphery of the connecting post 605, with both ends of the spring 606 abutting against the push block 604 and the arc-shaped baffle 607, respectively. To allow gas to enter and exit, the cylinder wall of the air cylinder 601 has an oxygen inlet 602 and an oxygen outlet 603. The equipment also includes a cover for aquaculture. The ventilation assembly 2 of the tank 1 includes a ventilation plate 201 and a rotating column 3. The ventilation plate 201 and the rotating column 3 are rotatably connected to facilitate opening the breeding tank 1. More specifically, a ring sleeve 202 is fixedly connected to the ventilation plate 201. The ring sleeve 202 is rotatably fitted onto the rotating column 3, forming the above-mentioned rotatable connection structure. In order to lock the ventilation plate 201 in the closed position, the equipment also includes a fixing assembly 4. The fixing assembly 4 includes a fixing column 402 fixed to the breeding tank 1 and a fixing plate 401 provided on the ventilation plate 201 and which can be inserted into the fixing column 402. A pin 203 can also be detachably installed on the fixing plate 401. The pin 203 is used to lock the fixing plate 401 onto the ventilation plate 201. The equipment also includes a cover 8, which covers the oxygenation mechanism 6 and the power mechanism 7 to protect the internal mechanism.

[0022] Working principle: When the motor 704 starts, it drives the second rotating shaft 706 to rotate. This rotation drives the oxygenation mechanism 6 and the cleaning mechanism 5 simultaneously through two paths. On the one hand, the rotation of the second rotating shaft 706 directly drives the cam 705, which is fixedly connected to the second rotating shaft 706, to rotate synchronously, thereby driving the oxygenation mechanism 6. On the other hand, the second rotating shaft 706 drives the first rotating shaft 702 to rotate synchronously through the meshing of the gear 703, thereby driving the cleaning mechanism 5 through belt transmission. In the oxygenation mechanism 6, the contour of the rotating cam 705 periodically abuts against and pushes the arc-shaped baffle 607 to move. The arc-shaped baffle 607 drives the pusher 604 to slide inside the air cylinder 601 through the fixedly connected connecting column 605. The sliding of the pusher 604 forces the gas in the air cylinder 601 into the breeding tank 1 from the oxygen outlet 603. When the cam 705 rotates and no longer abuts against the arc-shaped baffle 607, the spring 606 sleeved on the connecting column 605 rebounds and pulls the pusher 604 back to its initial position. External gas is then drawn into the air cylinder 601 through the oxygen inlet 602. This cycle repeats to achieve continuous oxygenation. In the cleaning mechanism 5, the rotation of the first rotating shaft 702 is transmitted to the threaded rod 501 through the second pulley 701 fixed on the first rotating shaft 702, the belt, and the first pulley 504 fixed on the threaded rod 501, causing the threaded rod 501 to rotate. Since the scraper 503 is threadedly engaged with the threaded rod 501, and the movement of the scraper 503 is restricted by the sliding guide of the limiting post 502 and cannot rotate, the rotational motion of the threaded rod 501 is converted into the linear reciprocating motion of the scraper 503 along the axial direction of the threaded rod 501, thereby achieving the cleaning of the water surface.
