Description

Technical Field

[0001] The present invention relates to the field of purification of breeding and cultivation water, and more particularly to a water environment purification device for fry cultivation. Background Art

[0002] Fry cultivation has strict requirements for water quality because water quality directly affects the growth rate and survival rate of fry. To maintain an ideal cultivation environment, specialized water environment purification equipment is usually required. These devices can effectively remove pollutants such as suspended solids, organic matter, nitrogen, and phosphorus in water, while maintaining the dissolved oxygen level and beneficial microorganism balance in the water body.

[0003] Currently, fry cultivation is divided into pond free-range cultivation and cultivation pond cultivation. The cultivation method in the cultivation pond has a unique innovative fry cultivation environment. The cultivation method in the cultivation pond has a separate water purification system and multiple functions such as automatic oxygenation and fish food feeding, which can reduce the manual burden during the fry cultivation process.

[0004] The water environment purification equipment for fry cultivation ponds generally requires a complete set of purification systems to ultrafilter the water source, but this will result in a very high cultivation cost for the cultivation pond. Moreover, the water source for fry cultivation in the cultivation pond is purified through an up-and-down water circulation method, which requires the continuous operation of the equipment. It is difficult to quickly purify the impurities in the water source for a long time, and it will also increase the cost of the cultivation pond.

[0026] In the scheme of the present application: through the design of the lifting blocking cover inside the breeding pond and the vortex circulation part in the center, the fry can be lifted to the upper part when purifying the water source, leaving the water source below in an empty state, and the high-speed rotation of the double-blade turbine is used to form a vortex in the center of the water source, so that impurities in the water are gathered in the center, absorbed by the double-blade turbine and enter the sewage purification box for purification and then discharged. It has a high-efficiency water source purification speed, and the purification cost is low, which is easy to promote and use.

[0027] 1. The present invention provides a lifting barrier cover inside the breeding pond, which can lift the fry to the top of the water pool during the water source purification process inside the breeding pond, leaving the water source below vacant, so as to facilitate the unified driving of the water source for rapid absorption and circulation purification. At the same time, after the lifting barrier cover is lifted, the bottom is still in the water source, which prevents the fry from leaving the water source and jumping out of the breeding pond. The opening of the partition inclined groove of the mesh bottom plate at the bottom of the lifting barrier cover can form an oxygen supply partition between the mesh bottom plate and the sewage purification box, so that the oxygen entering the breeding pond can be evenly transported to all positions.

[0028] 2. The present invention is provided with a vortex circulation part at the inner center of the sewage purification box. After the lifting and blocking cover lifts the fry to the upper side, the upward movement of the lifting and blocking cover can be utilized to synchronously pull the vortex circulation part upward, unfold the double-blade turbine in the middle of the water source, and through the rotation of the double-blade turbine, the water source can be conveyed into the sewage purification box, and the water in the middle of the breeding pond can be rotated to form a vortex to gather water impurities, realizing the function of quickly absorbing and purifying the water source. A coarse filter cloth layer and an activated carbon adsorption ring are respectively arranged at the inner bottom and the outer side of the inner part of the sewage purification box, which can ensure the quality of water source purification. During the rotation of the double-blade turbine, the cleaning brush rod can be synchronously driven to rotate, realizing the automatic cleaning of the coarse filter cloth layer and maintaining the water source purification function of the equipment for a long time.

[0029] 3. The present invention is provided with a sewage intake cover at the inner lower side of the coarse filter cloth layer at the center of the sewage purification box to cover the conical sewage outlet. After the equipment finishes working, the sewage intake cover can be opened through electromagnetic drive, and the impurities filtered by the coarse filter cloth layer can be directly discharged, improving the cleanliness effect inside the sewage purification box. At the same time, a sealing cover plate with elastic connection is provided at the center of the sewage intake cover, which can allow oxygen to be conveyed into the breeding pond through it.

[0030] 4. The present invention is provided with an electromagnetic shunt box at the water outlet position of the sewage pipe.

A second electromagnetic ring 78 is fixed to the side of the sealing baffle 77 close to the first electromagnetic ring 73. A rubber sealing sleeve 74 is sleeved on the outer sides of the first electromagnetic ring 73 and the second electromagnetic ring 78. The first electromagnetic ring 73 electromagnetically drives the sealing baffle 77 to slide on the outer wall of the T-shaped sliding rod 75 through the second electromagnetic ring 78.

[0084] An electromagnetic flow diversion box 7 is provided at the water outlet position of the sewage discharge pipe 35. It can drive the sewage discharge air inlet cover 6 and the sealing baffle 77 to open simultaneously through electromagnetic synchronization during sewage discharge, allowing the sewage to be discharged through the sewage discharge hose 72. It can also use the oxygen delivery pump 712 to deliver oxygen into the sewage discharge pipe 35 after sewage discharge, and deliver it into the sewage purification box 3 through the oxygen delivery port 64. The oxygen enters the oxygen delivery partition layer through the water purification outlet 32, and the oxygen is diverted to the lower side of the mesh bottom plate 22 and evenly delivered upward to increase the oxygen content in the aquaculture pond 1.

[0085] The usage process of a water environment purification device for fry aquaculture provided by the present invention is as follows:

[0086] When purifying the water source inside the aquaculture pond 1, start the electric lifting rod 11 to drive the lifting connecting plate 21 to drive the lifting blocking cover 2 to move upward above the aquaculture pond 1. When the lifting blocking cover 2 moves upward, the mesh bottom plate 22 connected to its bottom surface will move upward accordingly, and the fry located inside the mesh bottom plate 22 and the lifting blocking cover 2 will move upward with the mesh bottom plate 22, thus forming a state where the water source at the bottom of the aquaculture pond 1 is vacant.

[0087] When the mesh bottom plate 22 moves upward, the drive box 24 connected to the center of the mesh bottom plate 22 will move upward accordingly. The upward movement of the drive box 24 will drive the waterproof motor 41 to move upward. The upward movement of the waterproof motor 41 will drive the drive main shaft 42 to move upward. The upward movement of the drive main shaft 42 will cause the bottom end of it to be limited and slide inside the limit chute 435 opened in the center sleeve shaft 434. When the drive main shaft 42 moves upward to the upper part of the center sleeve shaft 434, with the continuous upward movement of the drive main shaft 42, the drive main shaft 42 will drive the double - blade turbine 43 to move upward. When the double - blade turbine 43 moves upward, since its outer wall is connected to the extension slide base 45 in a limited way through a bearing, the double - blade turbine 43 will drive the extension slide base 45 to move upward inside the positioning chute 452 through the positioning slider 451. When the positioning slider 451 slides above the positioning chute 452, the electric lifting rod 11 stops. At this time, the water - stirring upper blade 432 of the double - blade turbine 43 will slide to the outside of the water inlet storage box 33.

[0088] During the upward movement of the double - blade turbine 43, the cleaning brush rod 44 connected to its bottom surface will move upward accordingly, while the weight - increasing slide rod 442 that is limited and slides inside the cleaning brush rod 44 will slide inside the cleaning brush rod 44 under its own weight, increasing the length of the cleaning brush rod 44. When the double - blade turbine 43 slides to the uppermost position, the weight - increasing slide rod 442 will be fully extended.

[0089] During the upward movement of the extension slide base 45, the coarse filter cloth layer 5 connected to its bottom surface will move upward accordingly. And since the coarse filter cloth layer 5 is in a folded state, during the upward movement following the extension slide base 45, the coarse filter cloth layer 5 will gradually unfold. When the extension slide base 45 moves to the uppermost position, the coarse filter cloth layer 5 will be fully unfolded. At this time, the cleaning hard brush 443 on the outer wall of the cleaning brush rod 44 will abut against the surface of the unfolded coarse filter cloth layer 5.

[0090] When the lifting baffle cover 2 moves up to the uppermost position and the vortex circulation part 4 is fully unfolded, start the waterproof motor 41, and it can drive the double-blade turbine 43 to rotate by driving the main shaft 42. The rotation of the double-blade turbine 43 will drive the water-stirring upper blade 432 and the pressurizing lower blade 433 to rotate simultaneously. The rotation of the water-stirring upper blade 432 will stir the water source inside the breeding pond 1 to form a vortex, and when stirring the water source, use the angle of the water-stirring upper blade 432 to pressurize and transport the water source inside the breeding pond 1 to the inside of the water inlet 431. When the water source enters below the double-blade turbine 43 through the water inlet 431, the incoming water source will be quickly transported to the inside of the water inlet receiving box 33 under the suction force of the rotation of the pressurizing lower blade 433. When the water source enters the inside of the water inlet receiving box 33, under the continuous transportation of the subsequent water source, the water source will be filtered through the coarse filter cloth layer 5 and transported to the inside of the circulation chamber 31. After being adsorbed by the activated carbon adsorption ring 51 on the outer side of the inside of the circulation chamber 31, the water source will be transported to the inside of the breeding pond 1 through the purified water outlet 32, and the water source discharged through the purified water outlet 32 will rotate along the vortex on the outer circle inside the breeding pond 1, so that the dirty water can gradually be absorbed by the double-blade turbine 43 for purification, enabling the water source inside the breeding pond 1 to be quickly purified. During the process of purifying the water source, the fry are in the upper water source and will not be exposed to the air..

[0091] It should be noted that: the bottom of the driving main shaft 42 is limited and slides inside the central sleeve shaft 434, and due to this limitation, the central sleeve shaft 434 can also be driven to rotate when the driving main shaft 42 rotates.

[0092] After the water source inside the breeding pond 1 is purified, start the electromagnetic ring and the electromagnet 63. Through the repulsive magnetic force provided by the electromagnetic ring, push the second electromagnetic ring 78 to drive the sealing baffle 77 to slide towards the distal end of the T-shaped sliding rod 75, and open the sewage discharge port sealed by the rubber sealing sleeve 74 between the first electromagnetic ring 73 and the second electromagnetic ring 78.

[0093] After the electromagnet 63 is started, it provides a repulsive magnetic force with the permanent magnet block 62, drives the permanent magnet block 62 to push the lifting sliding rod 61 to move up, and enables the lifting sliding rod 61 to push the sewage inlet cover 6 to move up, so that the dirt remaining in the purified water source inside the coarse filter cloth layer 5 can be transported to the sewage discharge hose 72 through the sewage discharge pipe 35 and discharged.

[0094] After the sewage is discharged, start the first electromagnetic ring 73 and the first electromagnet 63 to be in an attracting state, which can close the position of the sewage discharge hose 72. At the same time, when the electromagnet 63 is started to provide an attracting magnetic force with the permanent magnet block 62, the permanent magnet block 62 can be adsorbed, enabling the permanent magnet block 62 to drive the lifting sliding rod 61 to drive the sewage inlet cover 6 to move down and close the sewage discharge pipe 35.

[0095] When the device is powered off, since the second electromagnetic ring 78 applies elastic force through the booster spring 76 of the T-shaped slide bar 75, the second electromagnetic ring 78 will always be in a state of closing the sewage discharge hose 72. Therefore, the discharge of the water source inside the breeding pond 1 can be avoided, ensuring the safety of fry breeding.

[0096] After the water purification and sewage discharge are completed, as the electric lifting rod 11 descends, the lifting blocking cover 2 and the mesh bottom plate 22 will descend simultaneously, driving the drive box 24 to descend. The descent of the drive box 24 will drive the waterproof motor 41 to descend, the descent of the waterproof motor 41 will drive the drive main shaft 42 to move downward, and the downward movement of the drive main shaft 42 will cause the double-blade turbine 43 and the extension slide seat 45 to move downward. After the drive main shaft 42 moves to the lowest position, if the double-blade turbine 43 and the extension slide seat 45 have not moved downward, the drive main shaft 42 will push the double-blade turbine 43 downward, causing the double-blade turbine 43 and the extension slide seat 45 to move to the lowest part of the water inlet storage box 33 simultaneously, completing the storage of the vortex circulation part 4. At the same time, the coarse filter cloth layer 5 will also fold and contract.

[0097] During the downward movement of the double-blade turbine 43, it will push the cleaning brush rod 44 downward, causing the cleaning brush rod 44 and the weight-increasing slide rod 442 to contract. When the device is powered off, if the sewage inlet cover 6 has not been closed, since the pressing base 444 at the bottom of the weight-increasing slide rod 442 abuts against the inside of the sewage inlet cover 6 after the double-blade turbine 43 is stored, the sewage inlet cover 6 can be pushed to close through the cleaning brush rod 44, ensuring that the water source inside the breeding pond 1 will not flow out.

[0098] During the process of breeding fry in the breeding pond 1, if oxygen needs to be supplied to the inside of the breeding pond 1, the oxygen supply pump 712 can be started to supply oxygen to the electromagnetic shunt box 7, and the oxygen will enter the sewage purification box 3 through the conical sewage outlet 34 connected to the sewage pipe 35.

[0099] When the oxygen reaches the position of the conical sewage outlet 34, as the pressure of the oxygen increases, the oxygen will push the sealing cover plate 65 at the oxygen outlet 64 to open, allowing the oxygen to enter the sewage purification box 3. Since the sealing cover plate 65 at the oxygen outlet 64 is provided with a return spring 67, the sewage inlet cover 6 will be in a sealed state when oxygen is not supplied.

[0100] When the oxygen enters the sewage purification box 3, it will be shunted into dense water bubbles through the coarse filter cloth layer 5, and then pass through the activated carbon adsorption ring 51 again to reach the water purification outlet 32. The dense water bubbles passing through the water purification outlet 32 will enter the space between the bottom surface of the mesh bottom plate 22 and the top surface of the sewage purification box 3 through the partition inclined groove 23. After passing through the partition, the water bubbles will be discharged upward through the mesh holes of the mesh bottom plate 22 under the action of water pressure, thus realizing the function of uniform oxygen supply.

[0101] It should be noted that: the interior of the activated carbon adsorption ring 51 is an activated carbon adsorption layer. Through the annular design of the activated carbon adsorption layer, the water source inside the circulation chamber 31 can be completely filtered and discharged evenly upward.
