Description

Technical Field

[0001] This application relates to the technical field of pond aquaculture, and in particular to a mobile aquaculture solid-liquid separation device. Background Technology

[0002] In pond aquaculture, in order to increase production and pursue economic benefits, intensive farming models with high stocking density and high feed intake are commonly adopted. As a result, the soil and water pollution caused by aquaculture wastewater is becoming increasingly prominent, which is a key issue that the aquaculture industry urgently needs to address.

[0003] In current fish farming ponds, there is usually a pond body where fish are raised. Fish feeders are set up on the banks of the pond body. When it is necessary to feed the fish, the fish feeder is first put into the fish feeder, and then the fish feeder is set to start on a timer. When the fish feeder is started, it throws the fish feed into the pond body for the fish to eat.

[0004] In the process of developing this application, the inventors discovered at least the following problems with this technology: Since fish eat and defecate in the same pond, the bottom of the pond often accumulates a thick layer of silt and fish feces. Over time, the fish feces ferment in the pond water, producing a large number of bacteria. If the fish feces are not cleaned up in time, not only will the water quality not be stable, but the fish will also be prone to disease, resulting in losses. Summary of the Invention

[0005] To facilitate centralized cleaning of fish waste, this application provides a mobile aquaculture solid-liquid separation device.

[0006] This application provides a mobile solid-liquid separation device for aquaculture, which adopts the following technical solution:

[0007] A mobile aquaculture solid-liquid separation device includes a pond body, a fish feeder is installed on the bank of the pond body, a lifting fence is installed inside the pond body, the lifting fence includes multiple lifting rods, a canvas is installed on the outside of the multiple lifting rods, the canvas encloses to form a feeding area, and a collection mechanism for collecting manure residue is installed in the feeding area.

[0008] By adopting the above technical solution, when it is necessary to feed the fish, first place the bait in the fish feeder, then align the feeding range of the fish feeder with the feeding area, and then start the fish feeder. When the fish bait is scattered in the feeding area, the fish will react and gather in the feeding area. After the fish have gathered in the feeding area, without disturbing the fish, slowly start the lifting rod. The lifting rod will drive the outer canvas to rise, thereby enclosing the fish in the feeding area for a short time. The fish will defecate soon after eating, and finally the fish feces in the feeding area will be cleaned up by the collection mechanism. In the above process, the fish are induced to eat and defecate in the feeding area, which not only helps to clean up fish feces or fish bait residue, but also helps to maintain the stability of the pond water quality.

[0009] Optionally, the collection mechanism includes a waterwheel aerator and a feed guide seat. The waterwheel aerator is offset within the feeding area and fixed to the water surface. The feed guide seat is located within the feeding area and divides the feeding area into a collection sub-area and a feeding sub-area. The feed guide seat includes a counterweight ring and a ring cloth. The ring cloth is wrapped around the side wall of the counterweight ring, and the side of the ring cloth facing away from the counterweight ring is connected to the inner side of the lifting fence. A suction component for suctioning fecal residue is provided in the collection sub-area.

[0010] By adopting the above technical solution, when the waterwheel aerator is started, the impeller of the waterwheel aerator stirs the water in the pond. Since the waterwheel aerator is biased towards the feeding area, it not only increases the oxygen content in the feeding area, thus avoiding fish gathering and insufficient oxygen, but also promotes the continuous flow of water in the feeding area in one direction, forming a micro underwater vortex. At the same time, with the guiding action of the feed guide seat, the counterweight ring forms a funnel shape in the pond water, thereby quickly collecting the feces and sludge that have settled in the feeding area through the feed guide seat to the collection sub-area. Finally, the suction component completes the cleaning of the feces and sludge, which helps to improve the stability of feces and sludge collection and cleaning.

[0011] Optionally, the suction assembly includes a collection box disposed within the collection sub-area. A flexible hose is connected to the top of the collection box, and one end of the flexible hose opposite to the collection box is connected to the counterweight ring. A suction pump is disposed in the collection sub-area. A suction pipe is connected to the inlet end of the suction pump and is connected to one side of the bottom of the collection box. A sewage pipe is connected to the outlet end of the suction pump and extends to the outside of the pond body.

[0012] By adopting the above technical solution, when the manure passes through the counterweight ring, it is collected in the collection box through the hose. When the suction pump is started, the manure passes through the suction pipe and the sewage pipe in sequence, and is finally discharged out of the pond body. The collection box is conducive to initially containing a large amount of manure and filtering the pond water in the manure, avoiding blockage of the suction pipe when a large amount of manure and pond water flow into it, thereby improving the stability of manure collection and cleaning.

[0013] Optionally, the lifting rod includes a rod cylinder and a telescopic sub-rod. The rod cylinder is disposed within the pond body, the telescopic sub-rod slides within the rod cylinder, the top end of the telescopic sub-rod penetrates through the rod cylinder, a pressure-boosting hole is provided on one side of the bottom of the rod cylinder, a limiting ring is provided around the side wall of the telescopic sub-rod, a pressure-relief hole is provided on one side of the top of the rod cylinder, and the pond body is provided with a pressure-boosting component.

[0014] By adopting the above technical solution, when the canvas needs to be raised, the pressure is first slowly increased into the rod cylinder through the pressurizing component. At this time, the pressure enters into the rod cylinder through the pressurizing hole, while the original pressure in the rod cylinder is discharged through the pressure relief hole, thereby slowly driving the telescopic rod to rise. The telescopic rod drives the canvas to slowly rise and enclose the area. Conversely, when the pressurizing component is activated under negative pressure, the pressure telescopic rod slowly retracts into the rod cylinder, and the telescopic rod drives the canvas to slowly descend, releasing the enclosure. By controlling the pressure of the pressurizing component, the speed of the canvas raising and lowering can be controlled, minimizing the noise during the raising and lowering of the canvas, which in turn helps to improve the stability of enclosing fish in the feeding area.

[0015] Optionally, adjacent rod cylinders are provided with a connecting mechanism, the connecting mechanism including a connecting rope, a fixing box is provided on the side wall of the rod cylinder, a fixing shaft is provided inside the fixing box, a winding wheel is rotatably sleeved on the fixing shaft, one end of the connecting rope is wound on the winding wheel, and a locking ring is provided on the side of the rod cylinder away from the fixing box.

[0016] By adopting the above technical solution, when it is necessary to connect adjacent lifting rods, first pull one end of the connecting rope out of the fixing box, and then fix one end of the connecting rope in the locking ring of the adjacent lifting rod. Repeat this process, and the lifting rods and connecting ropes initially enclose and form the skeleton of the feeding area. The connecting ropes help to strengthen the stability between adjacent lifting rods and prevent some lifting rods from deforming when fish hit the canvas, thereby improving the stability of the enclosure formed by the feeding area.

[0017] Optionally, the fixing box is provided with a winding assembly for cooperating in winding the connecting rope. The winding assembly includes a coil spring. A receiving groove is provided on one side of the winding wheel. The coil spring is disposed in the receiving groove. One end of the coil spring is fixedly connected to the fixing shaft, and the other end of the coil spring is fixedly connected to the inside of the receiving groove.

[0018] By adopting the above technical solution, when the connecting rope is stretched from the fixed box, the connecting rope drives the winding wheel to rotate. At this time, the coil spring deforms elastically. When the connecting rope is released, the coil spring releases its elastic force and drives the winding wheel to rotate in the opposite direction. At this time, the winding wheel winds the connecting rope inside, which helps to improve the convenience of storing the connecting rope. At the same time, when the connecting rope is fixed to the adjacent lifting rod, the elastic action of the coil spring helps to tighten the adjacent lifting rod, improving the stability of the enclosure of the feeding area.

[0019] Optionally, the side wall of the locking ring is provided with an opening section, the opening section has a sliding groove, a closing rod slides through the sliding groove, a spring is provided in the sliding groove, one end of the spring is connected to the closing rod, and the other end of the spring is connected to the groove wall.

[0020] By adopting the above technical solution, when it is necessary to fix the connecting rope, first push the closing rod. At this time, the closing rod compresses the spring and the opening section is set open. At this time, the connecting rope can be put into the locking ring. Then, release the closing rod, the spring releases the elastic force, and drives the closing rod to close the opening section. At this time, the connecting rope is fixed on the locking ring, which helps to improve the stability of the connecting rope fixed to the adjacent lifting rod.

[0021] Optionally, the canvas includes a fixed fabric body, a folded fabric body, and a lifting fabric body. The folded fabric body is disposed between the fixed fabric body and the lifting fabric body. A movable ring is provided on one side of the fixed fabric body, and the movable ring is engaged with the rope wall of the connecting rope. A female adhesive is provided on one side of the lifting fabric body, and a male adhesive is provided on the side wall of the telescopic rod. The female adhesive and the male adhesive are bonded to each other.

[0022] By adopting the above technical solution, when it is necessary to install the canvas, first fasten the snap ring on the fixed fabric body to the rope wall of the connecting rope, and then stick the female sticker on the lifting fabric body to the female sticker on the telescopic rod. When the telescopic rod is raised, the telescopic rod drives the lifting fabric body to rise, and the lifting fabric body drives the folded fabric body to unfold, which helps to improve the stability of the canvas lifting and enclosure.

[0023] Optionally, the folded fabric body includes multiple pieces of sub-fabric, which are sewn together. The canvas is provided with a folding assembly for folding and storing the multiple pieces of sub-fabric. The folding assembly includes an elastic cord, with folding holes penetrating the surfaces of the multiple pieces of sub-fabric located in the middle. The elastic cord is disposed in the folding holes, and its two ends are respectively connected to the first and last pieces of sub-fabric.

[0024] By adopting the above technical solution, when the folded fabric is unfolded, multiple pieces of fabric unfold in sequence. At this time, the elastic rope stretches elastically. When the canvas descends, the elastic rope drives the multiple pieces of fabric to fold one by one, which helps to avoid the canvas from getting knotted during folding, and thus helps to improve the stability of the canvas lifting and enclosing.

[0025] In summary, this application includes the following beneficial technical effect:

[0026] When feeding fish, first determine the location and size of the feeding area in the pond. Then, construct the framework of the feeding area using multiple lifting rods and connecting ropes. Next, secure the canvas with adjustable rings and adhesive tape to complete the feeding area setup. When feeding begins, place the bait in the feeder and align its feeding range with the feeding area. Then, activate the feeder. As the bait is scattered in the feeding area, the fish will react and gather there. Once the fish are gathered, slowly activate the lifting rods without disturbing them. The lifting rods will raise the outer canvas, briefly confining the fish within the feeding area. After eating, the fish will soon defecate. Finally, a collection mechanism will clean up all the fish waste in the feeding area. This process guides the fish to eat and defecate uniformly in the feeding area, which not only facilitates the centralized cleaning of fish waste and leftover bait but also helps maintain stable water quality in the pond.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] Example:

[0037] See Figure 1 and Figure 2 A mobile aquaculture solid-liquid separation device includes a pond body 1. Fish feeders 11 are fixed on the bank of the pond body 1, and the number of fish feeders 11 can be set according to actual needs. A lifting fence 2 is fixedly installed inside the pond body 1. The lifting fence 2 includes lifting rods 3. There are multiple lifting rods 3. The outer walls of the multiple lifting rods 3 are covered with canvas 4. The two ends of the canvas 4 are closed to form a feeding area 21.

[0038] It should be noted that the shape of the feeding area 21 when viewed from above can be varied, such as circular, elliptical, or semi-circular, enclosed by the inner wall of the pond body 1, etc., and the space of the feeding area 21 occupies 10%-20% of the space of the pond body 1. In this embodiment, the shape of the feeding area 21 when viewed from above is circular, and the feeding area 21 is equipped with a collection mechanism for collecting fish feces and fish bait residue.

[0039] When constructing the feeding area 21, its specific location within the pond body 1 is first determined. Then, the framework of the feeding area 21 is constructed using multiple lifting rods 3, and finally, the canvas 4 is installed to form the feeding area 21. When feeding the fish, the bait is first placed in the bait feeder 11, and then the feeding range of the feeder 11 is adjusted so that it is aligned with the feeding area 21. The feeder 11 is then activated, and the fish gather in the feeding area 21 after reacting. Once the fish have gathered in the feeding area 21, the multiple lifting rods 3 are activated simultaneously, causing the canvas 4 to rise, thus briefly confining the fish within the feeding area 21. Since the fish usually defecate shortly after eating the bait, the fish feces and bait residue in the feeding area 21 can be collected and cleaned up using a collection mechanism.

[0040] For details, see Figure 2 and Figure 3 The lifting rod 3 includes a rod cylinder 31 and a telescopic sub-rod 32. The rod cylinder 31 is fixed inside the pond body 1 and is placed vertically. The telescopic sub-rod 32 slides and rises and falls inside the rod cylinder 31, and the top end of the telescopic sub-rod 32 passes through the rod cylinder 31 and extends to the outside of the top end of the rod cylinder 31. Canvas 4 is installed on the outer walls of the rod cylinder 31 and the telescopic sub-rod 32 respectively. A pressure-increasing hole 33 passes through one side of the bottom of the rod cylinder 31 and is connected to the inside of the rod cylinder 31. A limiting ring 34 is provided on the side wall fixing ring of the telescopic sub-rod 32, and a pressure-relief hole 35 passes through one side of the top end of the rod cylinder 31 and is connected to the inside of the rod cylinder 31. The limiting ring 34 helps to prevent the telescopic sub-rod 32 from blocking the pressure-relief hole 35. The pond body 1 is provided with a pressure-increasing component that pressurizes or depressurizes the pressure-increasing hole 33. The pressure-increasing component can be a pressure pump.

[0041] In practical use, the pressurization holes 33 on multiple rod cylinders 31 are first connected simultaneously through existing pipelines, and then the pipelines are connected to a booster pump. To avoid disturbing the feeding fish, the booster pump can slowly pressurize the pressurization holes 33, while the pressure inside the rod cylinder 31 is released through the pressure relief hole 35. At this time, the telescopic rod 32 slowly rises from the rod cylinder 31, which in turn drives the canvas 4 to rise slowly. Similarly, when it is necessary to lower the canvas 4, the booster pump can generate negative pressure, which will eventually drive the canvas 4 to descend slowly.

[0042] See Figure 2 and Figure 4To facilitate the construction of the feeding area 21's framework, a connecting mechanism is provided between adjacent rod cylinders 31, including a connecting rope 51. Two fixing boxes 5 are fixed to the side walls of the rod cylinders 31, spaced apart along the height of the rod cylinders 31. A fixing shaft 52 is fixed inside each fixing box 5, horizontally positioned, with a winding wheel 53 rotating on its side wall. The winding wheel 53 is used to unwind the connecting rope 51; one end of the connecting rope 51 is fixedly connected to the surface of the winding wheel 53, and the other end is free. A locking ring 6 is fixed to the side of the rod cylinder 31 opposite to the fixing box 5, and the free end of the connecting rope 51 is fixedly connected to the locking ring 6.

[0043] See Figure 4 To facilitate the winding of the connecting rope 51, the fixing box 5 is provided with a winding assembly, which includes a coil spring 55. The side wall of the winding wheel 53 is provided with a receiving groove 54, the coil spring 55 is installed in the receiving groove 54, and one end of the coil spring 55 is fixedly connected to the side wall of the fixing shaft 52, and the other end of the coil spring 55 is fixedly connected to the groove wall of the receiving groove 54.

[0044] When it is necessary to connect adjacent rod cylinders 31, first pull the free end of the connecting rope 51 out of the fixing box 5. At this time, the connecting rope 51 drives the winding wheel 53 to rotate, and the coil spring 55 elastically deforms. Then, the free end of the connecting rope 51 is fixedly fastened to the locking ring 6. When the connecting rope 51 is released, the coil spring 55 releases its elastic force and drives the winding wheel 53 to rotate in the opposite direction, thereby tightening the connecting rope 51, thus completing the construction of the feeding area 21 frame.

[0045] In addition, another function of winding the connecting rope 51 inside the fixing box 5 is to facilitate the storage of the connecting rope 51 during the initial transportation, thereby reducing the space occupied by the connecting rope 51.

[0046] For details, see Figure 5 The locking ring 6 has an open section 61 extending through its side wall, and one end of the locking ring 6 is a closed end, while the other end is an open end. A groove 62 is formed at the open end of the locking ring 6, extending along the arc length of the locking ring 6. A closing rod 63 slides within the groove 62, passing through the groove and extending into the open section 61. A spring 64 is also installed within the groove 62, with one end fixedly connected to the closing rod 63 and the other end fixedly connected to the groove wall of the groove 62.

[0047] When the closing rod 63 moves away from the closed end, it presses against the spring 64, causing the spring 64 to deform elastically. At this time, the free end of the connecting rope 51 can be looped onto the locking ring 6 through the open section 61. Then, the closing rod 63 is released, and the spring 64 releases its elastic force, causing the closing rod 63 to move closer to the open end. At this time, the open section 61 closes, and the connecting rope 51 is fixed inside the locking ring 6.

[0048] See Figure 2 and Figure 6 To facilitate the fixing of the canvas 4 to the outer wall of the pole 31 and the telescopic sub-pole 32, the canvas 4 consists of a fixed fabric body 41, a folded fabric body 42, and a lifting fabric body 43 from bottom to top, and the two are sewn together. A movable ring 44 is fixed to the side of the fixed fabric body 41 facing the pole 31. Multiple movable rings 44 are arranged in a rectangular array along the span of the fixed fabric body 41, and the movable rings 44 are fastened to the rope wall of the connecting rope 51. A female patch 45 is sewn to the side of the lifting fabric body 43 facing the telescopic sub-pole 32, and a male patch 36 is correspondingly fixed to the outer wall of the telescopic sub-pole 32, with the female patch 45 and the male patch 36 adhering to each other.

[0049] It should be noted that, see Figure 6 To minimize the risk of the folded fabric 42 bundling during folding, the folded fabric 42 comprises multiple pieces of fabric 46, which are sequentially sewn together. The folded fabric 42 is equipped with a folding assembly for folding and storing the multiple pieces of fabric 46, including elastic cords 47. Folding holes 48 are perforated on the surface of each piece of fabric 46 located in the middle section. The elastic cords 47 are sequentially passed through the folding holes 48, and both ends of the elastic cords 47 are sewn together to the first and last pieces of fabric 46, respectively.

[0050] When the telescopic rod 32 rises, the adhesive action between the female adhesive patch 45 and the female adhesive patch 36 causes the telescopic rod 32 to lift the fabric body 43, which in turn causes multiple pieces of fabric 46 to unfold. At this time, the elastic rope 47 pulls the elastic cord. When the telescopic rod 32 descends, the elastic rope 47 releases its elasticity and folds the multiple pieces of fabric 46 for storage.

[0051] For details, see Figure 1 , Figure 2 and Figure 7 The collection mechanism includes a waterwheel aerator 7 and a feed guide seat 71. The waterwheel aerator 7 is a commonly used aerator in aquaculture. The waterwheel aerator 7 is placed in the feeding area 21, and its placement point is located off-center from the circular feeding area 21. The waterwheel aerator 7 is fixed to the water surface by ropes. The feed guide seat 71 is also installed in the feeding area 21, and it vertically divides the feeding area 21 into a collection sub-area and a feeding sub-area. The feed guide seat 71 includes a counterweight ring 712 and a ring cloth 711. The ring cloth 711 is fixed to the outer wall of the counterweight ring 712, and multiple collars 72 are also fixed to the periphery of the ring cloth 711 away from the counterweight ring 712. The multiple collars 72 are respectively fastened to the corresponding locking rings 6. Under the natural gravity of the counterweight ring 712 and the interlocking action of the collar 72 and the locking ring 6, the guide seat 71 is funnel-shaped inside the pond body 1.

[0052] When the waterwheel aerator 7 is started, firstly, the impeller of the waterwheel aerator 7 stirs up water droplets on the water surface, increasing the oxygen content in the pond water and providing sufficient oxygen for the fish gathered in the feeding area 21, minimizing the risk of the fish dying from lack of oxygen. Secondly, because the waterwheel aerator 7 is located at an off-center position in this type of circular feeding area 21, as the impeller of the waterwheel aerator 7 continues to operate, a miniature vortex gradually forms in the pond water of the feeding area 21, thereby concentrating the floating or settled feces in the pond water to the center of the feeding area 21, and finally collecting them in the collection sub-area through the funnel-shaped feed guide seat 71 for the next step of collection and cleaning.

[0053] See Figure 7 To facilitate the collection and cleaning of manure residue in the collection sub-area, a suction assembly is provided. The suction assembly includes a collection box 8, which is fixed to the bottom of the pond body 1 and located within the collection sub-area. A flexible hose 81 is fixedly connected to the top surface of the collection box 8, and the end of the hose 81 facing away from the collection box 8 is fixedly connected to a counterweight ring 712. A suction pump 82 is fixedly installed within the collection sub-area. A suction pipe 83 is fixedly connected to the inlet end of the suction pump 82, and the end of the suction pipe 83 facing away from the suction pump 82 is fixedly connected to the collection box 8. A sewage pipe 84 is fixedly connected to the outlet end of the suction pump 82, and the end of the sewage pipe 84 facing away from the suction pump 82 passes through the canvas 4 and extends outside the pond body 1.

[0054] Therefore, with the assistance of the micro-vortex, the fecal residue in the feeding area passes sequentially through the ring cloth 711, the counterweight ring 712, and the hose 81 before being collected in the collection box 8. Since the filter holes in the collection box 8 are smaller than the volume of the fecal residue, when the suction pump 82 is started, the fecal residue, along with a portion of the pond water, is sucked out of the pond body 1, thereby achieving the effect of cleaning the fecal residue.

[0055] It is worth noting that, see Figure 1 and Figure 2 To minimize the risk of manure falling into the collection area through the gap between the ring cloth 711 and the canvas 4, a filter ring 9 is installed at the top of the rod cylinder 31. The telescopic rod 32 passes through the filter ring 9 and is slidably connected to it.

[0056] Working principle of a mobile aquaculture solid-liquid separation device:

[0057] During the construction of the solid-liquid separation device, the location and size of the feeding area 21 in the pond are determined in advance, and then the lifting fence 2 is fixedly installed in that location. When it is necessary to feed the fish, the fish feeder 11 on the bank of the pond body 1 is activated simultaneously. At this time, the fish feeder 11 feeds the fish into the feeding area 21. The fish in the pond body 1 react and smell the fish, and then gather in the feeding area 21. When all the fish have gathered at the feeding area, the booster pump is activated. The booster pump simultaneously pressurizes the cylinder 31 through the pipeline. The pressure drives the telescopic rod 32 to slowly rise. The telescopic rod 32 drives the lifting cloth 43 to rise. At this time, the canvas 4 unfolds and surrounds the fish in the feeding area 21.

[0058] After the fish have finished feeding, the paddlewheel aerator 7 is activated. Taking advantage of the fish's tendency to defecate shortly after feeding, both eating and defecating occur in the designated feeding area 21, thus separating the feces from the pond water. The activated paddlewheel aerator 7 creates a miniature vortex in the pond water of the feeding area 21. When it is necessary to clean the feces, the suction pump 82 is activated. The feces pass through the feed guide seat 71 and the hose 81 and are collected in the collection box 8. The feces in the collection box 8 then pass through the suction pipe 83 and the sewage pipe 84 and are discharged outside the pond body 1, completing the cleaning of the feces.

[0059] In summary, gathering fish in feeding area 21 allows them to eat and defecate there, and then cleaning up the feces and sludge in feeding area 21 in a concentrated manner. This improves the ease of cleaning feces and sludge in the pond body 1 and helps maintain suitable water quality stability.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
