Description

Technical Field

[0001] This utility model relates to the field of eel farming technology, specifically to a suspended eel tank with graded temporary holding. Background Technology

[0002] Eels are a general term for species belonging to the order Anguilliformes. They are generally found in brackish waters where fresh and saltwater meet. When people farm eels on a large scale, they are usually placed in suspended ponds for cultivation.

[0003] In existing eel farming techniques, conventional suspended holding tanks lack a grading system, leading to cannibalism among eels of different sizes during mixed-species rearing, thus affecting growth efficiency and survival rates. Furthermore, since eel farming densities are typically maintained at high levels, if metabolic waste and uneaten feed are not promptly and effectively removed from the tanks, water quality will continuously deteriorate, hindering the sustainable development of eel farming. Therefore, we propose a suspended holding tank for eels with grading. Utility Model Content

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide a suspended eel tank with graded temporary holding.

[0005] A tiered temporary holding tank for eels includes: Water tank; A partition plate, which is installed inside the water tank, is used to divide the water tank into several independent areas; A sludge collection trough is provided on the bottom wall of the water tank; a flushing pipe and a drain pipe are respectively connected to both ends of the sludge collection trough. An electric telescopic pole, the output end of which is connected to a partition plate via a first connecting rod; The scraper has at least two pieces, which are located at the bottom of the water tank and on both sides of the partition plate. The two scrapers are connected to the first slider and the second slider respectively through the second connecting rod. A lead screw, the middle of which passes through and is threadedly connected to a first slider and a second slider, and the threaded holes on the first slider and the second slider have opposite helical directions. The lead screw is driven to rotate by a rotary motor. A sliding rod, the middle of which passes through and slides through the first and second sliders.

[0006] A further option is to install a water pump on the flushing pipe.

[0007] A further option is to uniformly provide several through holes on the partition plate.

[0008] A further embodiment is that the electric telescopic rod is installed on the first support plate on the outer wall of the water tank, and the first connecting rod is L-shaped.

[0009] A further embodiment is that a second support plate is installed on both sides of the outer wall of the water tank, the rotary motor is installed on the second support plate, the end of the lead screw away from the rotary motor is rotatably connected to the second support plate, and both ends of the slide rod are fixedly connected to the second support plate.

[0010] A further option is that the rotary motor has forward and reverse rotation functions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a partition plate in the hanging pool, the hanging pool is divided into several independent areas, which allows eels of different sizes to be raised in different areas, avoiding cannibalism that easily occurs when eels of different sizes are mixed. In addition, after the eels are taken out, the partition plate is moved up by an electric telescopic rod, so that the bottom of the independent areas in the hanging pool are connected. At this time, the rotary motor drives the lead screw to rotate, which drives the first slider and the second slider to move in opposite directions, so that the scraper can discharge metabolic waste, uneaten feed and other sludge in the hanging pool into the sludge collection tank, and then discharge the sludge from the hanging pool through the sludge collection tank. This makes it convenient to clean the sludge in the hanging pool without being affected by the partition plate, which is conducive to the sustainable development of eel farming.

[0014] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0016] Please see Figures 1-3 This utility model provides a graded temporary holding eel tank, including a tank 1; several partition plates 2 are installed inside the tank 1. The partition plates 2 are used to divide the tank 1 into several independent areas, thereby enabling eels of different sizes to be raised in different independent areas and avoiding cannibalism during mixed-species rearing. First connecting rods 4, L-shaped, are fixedly connected to the top two sides of the partition plates 2. Correspondingly, a first support plate 11 is installed on the outer wall of the tank 1, and an electric telescopic rod 12 is installed on the first support plate 11. The output end of the electric telescopic rod 12 is fixedly connected to the first connecting rods 4. When the electric telescopic rod 12 moves the partition plates 2 upwards, the partition plates 2 are separated from the bottom wall of the tank 1 by a certain distance, thus connecting the bottoms of the independent areas within the tank 1.

[0017] Preferably, the partition plate 2 is provided with several through holes evenly distributed on it, which allow water to flow freely in independent areas within the water tank 1.

[0018] The water tank 1 is also equipped with several scrapers 3 at intervals. At least two scrapers 3 are provided, located at the bottom of the water tank 1 and on either side of the partition plate 2. The two scrapers 3 are connected to the first slider 6 and the second slider 7 respectively via second connecting rods 5. A lead screw 8 passes through the first slider 6 and the second slider 7 and is threaded to them. The threaded holes on the first slider 6 and the second slider 7 have opposite helical directions. The lead screw 8 is driven to rotate by a rotary motor 10. Furthermore, a sliding rod 9 passes through the first slider 6 and the second slider 7 and slides with them. That is, the same scraper 3 is fixedly connected to two first sliders 6 or two second sliders 7 via two second connecting rods 5. The rotary motor 10 has forward and reverse rotation functions. Second support plates 17 are installed on both sides of the outer wall of the water tank 1. The rotary motor 10 is mounted on the second support plates 17. The end of the lead screw 8 away from the rotary motor 10 is rotatably connected to the second support plate 17, and both ends of the sliding rod 9 are fixedly connected to the second support plate 17. After the rotary motor 10 is started, it drives the lead screw 8 to rotate. Since the spiral directions of the threaded holes on the first slider 6 and the second slider 7 are opposite, the corresponding partition plates 2 of the first slider 6 and the second slider 7 will move closer to each other or separate from each other. A sludge collection trough 13 is also provided on the bottom wall of the water tank 1, and the sludge collection trough 13 is located between the two partition plates 2. When the electric telescopic rod 12 moves the partition plates 2 upward, the bottoms of the independent areas in the water tank 1 are connected. At this time, the rotary motor 10 drives the lead screw 8 to rotate, which drives the first slider 6 and the second slider 7 to move towards each other, which drives the scraper 3 to discharge metabolic waste, uneaten feed and other dirt in the water tank 1 into the sludge collection trough 13.

[0019] It should be noted that during the relative movement of the first slider 6 and the second slider 7, when the scraper 3 moves to the sludge collection trough 13, the second connecting rod 5 corresponding to the scraper 3 still has a certain gap with the partition plate 2, so that the scraper 3 will not collide with the partition plate 2 during the process of the scraper 3 discharging metabolic waste, residual feed and other sludge from the water tank 1 into the sludge collection trough 13.

[0020] Preferably, the two ends of the sludge collection tank 13 are connected to a flushing pipe 14 and a drain pipe 15, respectively. Valves are installed on both the flushing pipe 14 and the drain pipe 15. The end of the flushing pipe 14 furthest from the water tank 1 can be connected to a water tank, and the end of the drain pipe 15 furthest from the water tank 1 can be connected to a sewage treatment tank. A water pump 16 is installed on the flushing pipe 14. After the scraper 3 discharges metabolic waste, uneaten feed, and other pollutants from the water tank 1 into the sludge collection tank 13, opening the valves on the flushing pipe 14 and the drain pipe 15 and starting the water pump 16 flushes the pollutants from the sludge collection tank 13 into the drain pipe 15, and then discharges them from the water tank 1. This achieves efficient cleaning of pollutants in the water tank 1, and the cleaning process is not affected by the partition plate 2, which is beneficial to the sustainable development of eel farming.

[0021] It should be noted that the outer wall of the water tank 1 is equipped with control switches for the electric telescopic rod 12, the rotary motor 10, and the water pump 16; the control switches are not shown in the figure. Controlling the extension and retraction of the electric telescopic rod 12, the forward and reverse rotation of the rotary motor 10, and the start and stop of the water pump 16 through the control switches is existing technology, and this application does not improve or innovate in this regard.

[0022] The working principle of this utility model is as follows: When the bottom of the partition plate 2 contacts the bottom of the hanging water tank 1, the partition plate 2 divides the hanging water tank 1 into several independent areas; thus, eels of different sizes can be raised in different independent areas, avoiding cannibalism during mixed-species farming. After the eels have been raised for a period of time, the eels are removed and the water in the hanging water tank 1 is drained; then, the partition plate 2 is moved upward by the electric telescopic rod 12, so that the bottoms of the independent areas in the hanging water tank 1 are connected. At this time, the rotary motor 10 drives the lead screw 8 to rotate, which drives the first slider 6 and the second slider 7 to move towards each other, so that the scraper 3 can discharge metabolic waste, uneaten feed and other sludge in the hanging water tank 1 into the sludge collection trough 13, and the sludge is discharged from the hanging water tank 1 through the sludge collection trough 13; thus, it is convenient to clean the sludge in the hanging water tank 1 without being affected by the partition plate 2, which is conducive to the sustainable development of eel farming.
