Description

Technical Field

[0001] The invention belongs to the technical field of eel breeding, and in particular relates to a water intake device for eel breeding. Background Art

[0002] Eel farming is an important industry in aquaculture, especially in Asia. Eels have very strict requirements on water quality during the farming process. The quality and supply of water directly affect the growth, health and yield of eels. Therefore, water source management for eel farming is particularly important. Traditional farms mostly use groundwater or surrounding natural water bodies as water sources, but with the expansion of farming scale, the demand for water resources has increased significantly, and water quality issues have gradually become prominent. Effective water intake devices can not only ensure sufficient and clean water sources, but also reduce operating costs and improve the benefits of eel farming. Therefore, the development and application of efficient and energy-saving water intake equipment has become an important issue in modern eel farming.

[0003] Eel is a kind of fish that has a high demand for oxygen content in water. Therefore, it is extremely important to control the oxygen content in water for eel farming. The existing eel farming water intake device cannot replace different water layers in the pond during use, resulting in different oxygen contents in different water layers in the breeding pond. As a result, eels are in these oxygen-deficient water layers for a long time, which will cause breathing difficulties, metabolic disorders, and even death. In addition, traditional water intake devices can only complete simple water intake and cannot change the oxygen content of the water flow, thereby achieving poor water intake effect and reducing the working performance of the water intake device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a water intake device for eel breeding.

[0005] The technical solution adopted to solve the above technical problems is: an eel farming water intake device, comprising a main body, a plurality of buckles are fixedly connected to the outer wall of the main body, and a raft is fixedly connected to the inner wall of every two buckles;

[0006] An adjustment mechanism is installed inside the main body, a bracket is fixedly connected to the top of the outer wall of the adjustment mechanism, and an iron plate is fixedly connected to the top of the bracket;

[0007] A water intake mechanism is installed inside the regulating mechanism, and a moving mechanism is installed at the bottom of the water intake mechanism.

[0008] Furthermore, the adjustment mechanism includes a first motor fixedly connected to the inner wall of the main body, the output end of the first motor is fixedly connected to the first drive shaft, the other end of the first drive shaft is fixedly connected to a worm, a sleeve is slidably connected inside the main body, the outer wall of the sleeve is fixedly connected to a threaded strip, the inner wall of the main body is rotatably connected to a worm wheel, the outer wall of the threaded strip is threadedly connected to the main body, the inner wall of the worm wheel is threadedly connected to the threaded strip, and the bottom of the bracket is fixedly connected to the top of the outer wall of the sleeve.

[0009] Through the above technical scheme, when in use, multiple rafts can be fixed to the main body through corresponding buckles, and then they are completely placed in the water area of ​​the breeding pond. At this time, under the buoyancy of multiple rafts, the entire eel breeding water intake device can be completely floated on the water surface. By surrounding the main body with multiple rafts, the buoyancy can be maintained while maintaining its stability, ensuring that the eel breeding water intake device has sufficient stability during movement, and can ensure that the water intake device can float and move along the breeding pond when taking water, thereby ensuring the oxygen content of the overall water source of the eel breeding pond. Therefore, the eel breeding water intake device is more automated, with less manual participation and more convenient breeding. Subsequently, the regulating mechanism is used to adjust the height according to the water layer in the breeding pond, so that the water in different water layers can be quickly taken out. In the breeding pond, the dissolved oxygen content of the surface water is usually higher, while the oxygen content of the deep water is lower. By controlling The depth of the water intake can better ensure the balanced distribution of oxygen in each water layer in the pond. Especially when the breeding density is high, it is crucial to maintain a sufficient oxygen supply to ensure that the eels can move freely in the entire water body and stay healthy, and that the device can maintain stability during the adjustment and water intake process under the floating of multiple rafts. Specifically, the first motor on the inner wall of the main body is started to drive the worm at the other end of the first drive shaft to rotate. Under the conditions that the inner wall of the worm wheel is threadedly connected to the threaded strip and the inner wall of the main body is rotationally connected to the worm wheel, the worm wheel will be driven to rotate, and then the sleeve on its inner wall and the threaded strip will be driven to move up and down, and water will be taken from different water layers as needed. By adjusting the height of the water intake device, the upper or lower water with better water quality can be selectively extracted to avoid overly obvious water quality stratification in the water body and ensure the balance of the water environment.

[0010] Furthermore, the water intake mechanism includes a second motor fixedly connected to the top of the iron plate, the output end of the second motor is fixedly connected to a second driving shaft, the outer wall of the second driving shaft is fixedly connected to a plurality of support rods, wherein the other ends of a plurality of the second driving shafts are fixedly connected to threaded tubes, a plurality of the threaded tubes have water inlets at the bottom, a plurality of the threaded tubes have water outlets at the bottom, a plurality of the threaded tubes have fixedly connected to outer walls with fixing rings, the bottom of the fixing rings is rotatably connected to the sleeve, the plurality of threaded tubes are interlocked and overlapped with each other through threads, and the plurality of threaded tubes are located inside the sleeve.

[0011] Through the above technical scheme, after the adjustment of the water intake position in the water intake device is completed using the regulating mechanism, the water intake mechanism is used to draw water flows from different water layers to the top of the water intake device using the rotational movement trend, so as to achieve the water sprinkling of different water layers, increase the oxygen content in the water flows of different water layers, and thus assist the growth of eels in the breeding process. When the regulating mechanism moves up and down, it can drive the water intake mechanism to move downward or upward as a whole. When the regulating mechanism reaches the designated water layer to take water, as the water intake mechanism can be started to move, the water intake mechanism does not It can not only take away the water flow of the water layer, but also stir the water flow in the water layer so that the water flow of the water layer can be fully mixed. Water bodies usually have stratification between different water layers. The temperature, dissolved oxygen content and other water quality indicators of the bottom water and the upper water may be different. Stirring the water flow can break the stratification of the water layer and mix the water bodies of different layers, thereby balancing the dissolved oxygen content of the water body. This can avoid the adverse effects of low-oxygen areas in the bottom water on farmed animals. When taking water, the rotation and collision of the spiral tube can produce a more uniform water flow in the water body to avoid excessive concentration of water flow. The water can be evenly distributed in the water or in some places, which not only helps to increase the dissolved oxygen content of the water body, but also can more evenly distribute the nutrients and temperature in the water, which is beneficial to the healthy growth of eels. Subsequently, in the process of taking water and discharging water, inertia can be used to sprinkle it around, so that the water flow of different water layers can contact with the air. When it falls to the water surface, it can collide with the water surface, so that the water flow can be fully dispersed and the oxygen content is relatively increased. Specifically, when the sleeve falls to the specified water layer, the second motor on the top of the iron plate is started to drive the second drive shaft to rotate, and multiple When the support rod is fixed, the water inlet at the bottom of the multiple threaded tubes will contact the water source, and the water will be squeezed in from the water inlet. When rotating, the water will enter in sequence. At the same time, the direction of the water outlet at the top of the multiple threaded tubes is opposite to the direction of the water inlet at the bottom. Then, when rotating, the water inside the multiple threaded tubes can be swung to the surroundings by rotation to achieve the throwing of water, so that the water can completely fall to the water surface and collide with the water surface under the action of gravity, thereby increasing the oxygen content inside. At the same time, the water source contains sufficient oxygen content to better meet the breeding of eels.

[0012] Furthermore, the moving mechanism includes a disc fixedly connected to the bottom of the second driving shaft, a plurality of fixed columns are fixedly connected to the bottom of the disc, a plurality of paddle boards are fixedly connected to the bottom of the fixed columns, and the plurality of paddle boards, fixed columns and discs are all located at the bottom of the plurality of water inlets.

[0013] Through the above technical scheme, under the condition of normal operation of the water intake mechanism, the eel breeding water intake device can normally intake water, and at the same time, the mobile mechanism is used to accompany the movement of the water intake mechanism, so that the eel breeding water intake device floats in the breeding pond, avoiding the eel breeding water intake device from staying at a fixed point, and avoiding the device from floating to the shore and staying. Therefore, during the water intake process, the device can move in the breeding pond to ensure that the entire breeding area can perform water intake and oxygenation operations, and ensure the oxygen content in the breeding pond. As the breeding water intake device moves, the oxygen content of the water flow in the eel breeding pond can be fully covered. When the eel breeding water intake device moves, the water layer at the bottom is stirred as the movement is driven, thereby increasing the oxygen content of the water source, and The replacement of water source extraction from the lower part to the top water source ensures the oxygen content and temperature control of the water source, while also increasing the fluidity of the bottom water source. High dissolved oxygen content and good water flow can promote healthy water quality, which can inhibit the reproduction of harmful bacteria and pathogens. The higher the oxygen content in the water body, the less conducive it is to the growth of anaerobic pathogens, thereby reducing the risk of disease transmission during the breeding process. Specifically, with the rotation of the second drive shaft, the paddles on the multiple fixed columns of the bottom disc will be driven to rotate, thereby achieving the stirring of the water source, so that the eel breeding water intake device can move during the water intake process, thereby achieving not only the selection of the designated water layer, but also the mobile water intake of the surface area of ​​the breeding pond. Multiple paddles are located below the water inlet, so as not to hinder the water intake.

[0014] The beneficial effects of the present invention are as follows: (1) The present invention designs an adjusting mechanism, a water intake mechanism and a moving mechanism. When the eel water intake device is in use, the water intake height of the device is controlled to achieve water intake from different water layers in the breeding pond. Then, by taking water from different water layers, the breeding management personnel can control the water quality more accurately as needed, thereby adjusting the water quality conditions for different breeding stages and optimizing the breeding benefits. At the same time, water from different water layers can be extracted, and the extracted water can be sprinkled onto the water surface using the Archimedean pumping principle and a certain inertia, thereby increasing the oxygen content of different water layers; (2) The present invention designs an adjusting mechanism to change the height of the water inlet of the eel breeding water intake device, so that the water inlet can be adjusted to the height of the water inlet at different heights. Water can be drawn from different water layers. By controlling the depth of the water intake, the balanced distribution of oxygen in each water layer in the pond can be better guaranteed. Especially when the breeding density is high, it is very important to maintain a sufficient oxygen supply to ensure that the eels can move freely in the entire water body and stay healthy. At the same time, the low water temperature at the bottom can be regulated. (3) The present invention rotates and draws water from different water layers by designing a water intake mechanism and a moving mechanism, so that water sources from different water layers can be transmitted upward from the bottom and at the same time fall to the water surface under the action of inertia, so that the water flow collides with the surface water surface, thereby increasing the oxygen content of the water flow. In addition, during the floating process of the eel breeding water intake device, it can follow the movement during the water intake process to increase the water intake area.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] like Figure 1-Figure 8As shown, an eel farming water intake device of the present embodiment includes a main body 1, a plurality of buckles 2 are fixedly connected to the outer wall of the main body 1, a raft 3 is fixedly connected to the inner wall of every two buckles 2, an adjusting mechanism 4 is installed inside the main body 1, the adjusting mechanism 4 includes a first motor 401 fixedly connected to the inner wall of the main body 1, a first drive shaft 402 is fixedly connected to the output end of the first motor 401, a worm 403 is fixedly connected to the other end of the first drive shaft 402, a sleeve 404 is slidably connected inside the main body 1, a threaded strip 405 is fixedly connected to the outer wall of the sleeve 404, a worm gear 406 is rotatably connected to the inner wall of the main body 1, the outer wall of the threaded strip 405 is threadedly connected to the main body 1, and the worm gear 406 is rotatably connected to the inner wall of the main body 1. 6 The inner wall is threadedly connected with the threaded strip 405, and the bottom of the bracket 5 is fixedly connected with the top of the outer wall of the sleeve 404. When in use, multiple rafts 3 can be fixed on the main body 1 through the corresponding buckles 2, and then they are completely placed in the water area of ​​the breeding pond. At this time, under the buoyancy of the multiple rafts 3, the entire eel breeding water intake device can be completely floated on the water surface. By surrounding the main body 1 with multiple rafts 3, the buoyancy can be maintained and the stability can be ensured, so that the eel breeding water intake device has sufficient stability during movement, and the water intake device can float and move along the breeding pond when taking water, so as to ensure the overall water source of the eel breeding pond. Oxygen content, so the eel farming water intake device is more automated, less manual participation, and more convenient farming. Subsequently, the regulating mechanism 4 is used to adjust the height according to the water layer in the breeding pond, so that water in different water layers can be quickly taken out. In the breeding pond, the dissolved oxygen content of the surface water is usually higher, while the oxygen content of the deep water is lower. By controlling the depth of the water intake, the balanced distribution of oxygen in each water layer in the pond can be better guaranteed. Especially in the case of high breeding density, it is very important to maintain a sufficient oxygen supply to ensure that the eels can move freely in the entire water body and stay healthy, and can be adjusted and watered in the device under the floating of multiple rafts 3. The stability can be ensured. Specifically, the first motor 401 on the inner wall of the main body 1 is started to drive the worm 403 at the other end of the first driving shaft 402 to rotate. Under the condition that the inner wall of the worm wheel 406 is threadedly connected with the threaded bar 405 and the inner wall of the main body 1 is rotationally connected with the worm wheel 406, the worm wheel 406 will be driven to rotate, and then the sleeve 404 on the inner wall and the threaded bar 405 will be driven to move up and down. Water can be taken from different water layers as needed. By adjusting the height of the water intake device, the upper layer water or the lower layer water with better water quality can be selectively extracted to avoid obvious water quality stratification problems in the water body and ensure the balance of the water environment.

[0026] like Figure 6-Figure 8As shown, a bracket 5 is fixedly connected to the top of the outer wall of the adjusting mechanism 4, an iron plate 6 is fixedly connected to the top of the bracket 5, a water intake mechanism 7 is installed inside the adjusting mechanism 4, the water intake mechanism 7 includes a second motor 701 fixedly connected to the top of the iron plate 6, a second drive shaft 702 is fixedly connected to the output end of the second motor 701, a plurality of support rods 703 are fixedly connected to the outer wall of the second drive shaft 702, wherein the other ends of the plurality of second drive shafts 702 are fixedly connected to threaded tubes 704, a water inlet 705 is provided at the bottom of the plurality of threaded tubes 704, a water outlet 706 is provided at the bottom of the plurality of threaded tubes 704, a fixing ring 707 is fixedly connected to the outer wall of the plurality of threaded tubes 704, the bottom of the fixing ring 707 is rotatably connected to the sleeve 404, and the threads of the plurality of threaded tubes 704 are interlocked and overlapped. In addition, multiple threaded tubes 704 are all located inside the sleeve 404. When the water intake position in the water intake device is adjusted using the regulating mechanism 4, the water intake mechanism 7 is used to extract the water flow of different water layers to the top of the water intake device using the rotational movement trend, so as to achieve the water of different water layers. Sprinkling, increase the oxygen content in the water flow of different water layers, and thus assist the growth of eels during the breeding process. When the regulating mechanism 4 moves up and down, it can drive the water intake mechanism 7 to move downward or upward as a whole. When the regulating mechanism 4 reaches the designated water layer to take water, as the water intake mechanism 7 can be started to move, the water intake mechanism 7 can not only take away the water flow of the water layer but also stir the water flow in the water layer, so that the water flow of the water layer can be fully mixed. Water bodies usually produce stratification between different water layers. The temperature, dissolved oxygen content and other water quality indicators of the bottom water and the upper water may be different. Stirring the water flow can break the stratification of the water layers and mix the water bodies of different layers, thereby balancing the dissolved oxygen content of the water body. This can avoid the adverse effects of low-oxygen areas in the bottom water on farmed animals. When taking water, the rotation and collision of the spiral tube can produce a more uniform water flow in the water body, avoid excessive concentration or local accumulation of water flow, and make the water flow distribution more balanced. This not only helps to increase the dissolved oxygen content of the water body, but also can more evenly distribute the nutrients, temperature, etc. in the water, which is beneficial to the healthy growth of eels. Later, in the process of taking water and discharging water, inertia can be used to sprinkle it around, so that the water flow of different water layers can When the sleeve 404 falls to the specified water layer, the second motor 701 on the top of the iron plate 6 is started to drive the second drive shaft 702 to rotate. When the plurality of support rods 703 are fixed, the water inlet 705 at the bottom of the plurality of threaded tubes 704 will contact the water source, and the water will be squeezed in from the water inlet 705. In the case of rotation, the water will enter in sequence. At the same time, the direction of the water outlet 706 at the top of the plurality of threaded tubes 704 is opposite to the direction of the water inlet 705 at the bottom. In the case of rotation, the water flow inside the plurality of threaded tubes 704 can be thrown to the surroundings by rotation to achieve the throwing of the water flow.Therefore, the water flow can completely fall to the water surface and collide with the water surface under the action of gravity, increasing the oxygen content inside. At the same time, the water source contains enough oxygen to better meet the needs of eel breeding.

[0027] like Figure 7 As shown, a moving mechanism 8 is installed at the bottom of the water intake mechanism 7, and the moving mechanism 8 includes a disc 801 fixedly connected to the bottom of the second driving shaft 702, and a plurality of fixed columns 802 are fixedly connected to the bottom of the disc 801, and a plurality of fixed columns 802 are fixedly connected to the bottom of each of the paddle boards 803, and the plurality of paddle boards 803, the fixed columns 802 and the disc 801 are all located at the bottom of the plurality of water inlets 705. Under the condition that the water intake mechanism 7 operates normally, the eel breeding water intake device can normally intake water, and at the same time, the moving mechanism 8 is used to accompany the movement of the water intake mechanism 7 so that the eel breeding water intake device floats in the breeding pond, so that the eel breeding water intake device does not stay at a fixed point, and the device does not float to the shore and stays, so that during the water intake process, the device can move in the breeding pond to ensure that the entire breeding area can perform water intake and oxygenation operations, and ensure the oxygen content in the breeding pond. As the breeding water intake device moves, the water flow in the eel breeding pond can be fully oxygenated. It covers that when the eel breeding water intake device moves, the water layer at the bottom is stirred with the driving of the movement, thereby increasing the oxygen content of the water source. By replacing the bottom water source with the top water source, the oxygen content and temperature of the water source are guaranteed, and the fluidity of the bottom water source is increased. High dissolved oxygen content and good water flow can promote healthy water quality, which can inhibit the reproduction of harmful bacteria and pathogens. The higher the oxygen content in the water body, the less conducive it is to the growth of anaerobic pathogens, thereby reducing the risk of disease transmission during breeding. Specifically, with the rotation of the second drive shaft 702, the paddle plates 803 on the multiple fixed columns 802 of the bottom disc 801 will be driven to rotate, thereby realizing the stirring of the water source, so that the eel breeding water intake device can move during the water intake process, thereby realizing not only the selection of the specified water layer, but also the mobile water intake of the surface area of ​​the breeding pond. The multiple paddle plates 803 are all located below the water inlet 705, so as not to hinder the water intake.

[0028] The working principle of this embodiment is as follows. When in use, multiple rafts 3 can be fixed on the main body 1 through corresponding buckles 2, and then they are completely placed in the water area of ​​the breeding pond. At this time, under the buoyancy of multiple rafts 3, the entire eel breeding water intake device can be completely floated on the water surface, and then water is taken according to the specified water layer. Then, the first motor 401 on the inner wall of the main body 1 is started to drive the worm 403 at the other end of the first drive shaft 402 to rotate. Under the conditions that the inner wall of the worm gear 406 is threadedly connected with the threaded strip 405 and the inner wall of the main body 1 is rotationally connected with the worm gear 406, the worm gear 406 will be driven to rotate, and then the sleeve 404 on its inner wall and the threaded strip 405 will be driven to move up and down. When the sleeve 404 falls to the specified water layer, the iron plate 6 is started at this time. The second motor 701 at the bottom drives the second driving shaft 702 to rotate, and under the fixation of the multiple support rods 703, the water inlet 705 at the bottom of the multiple threaded tubes 704 will contact the water source, and the water will be squeezed in from the water inlet 705. In the case of rotation, the water flow will enter in sequence. At the same time, the direction of the water outlet 706 located at the top of the multiple threaded tubes 704 is opposite to the direction of the water inlet 705 at the bottom, and then in the case of rotation, the water flow inside the multiple threaded tubes 704 can be swung to the surroundings by rotation to achieve water sprinkling. With the rotation of the second driving shaft 702, the paddle plates 803 on the multiple fixed columns 802 of the bottom disc 801 will be driven to rotate, thereby achieving the stirring of the water source, so that the eel farming water intake device can move during the water intake process.
