Description

Technical Field

[0001] This application relates to the technical field of fishpond bottom improvement, and in particular to a fishpond with a bottom improvement system and a high-temperature fish harvesting method. Background Technology

[0002] Fish ponds, often called fishponds, are primarily used for raising fish for consumption. When raising fish in ponds, as feeding time increases, large amounts of uneaten feed, feces, and other organic matter easily accumulate at the bottom. If the bottom of the pond is not regularly cleaned, the accumulated organic matter can easily transform into toxic substances such as nitrite and hydrogen sulfide, causing stress to the fish and leading to osteoporosis.

[0003] Therefore, fishpond aquaculture requires regular bottom cleaning to remove accumulated organic matter. However, to minimize the risk of injury to the fish, it's necessary to remove them from the pond before cleaning, which is quite troublesome. Summary of the Invention

[0004] To facilitate bottom modification of fish ponds, this application provides a fish pond with a bottom modification system and a high-temperature fish harvesting method.

[0005] In a first aspect, this application provides a fishpond with a bottom-modification system, employing the following technical solution:

[0006] A fishpond with a bottom improvement system, including

[0007] The pool body forms a pool cavity;

[0008] The mounting frame slides up and down in the pool cavity, the outer wall of the mounting frame slides in contact with the wall of the pool cavity, and multiple support columns are evenly spaced inside the mounting frame, forming an installation space between the mounting frame and the support columns;

[0009] An interception net is installed on the supporting column, and the interception net blocks the installation space in a one-to-one correspondence;

[0010] A lifting assembly is installed in the pool body, and the lifting assembly controls the mounting frame to slide up and down.

[0011] A filter cartridge is installed outside the pool body. A water pump is installed inside the filter cartridge. The water pump is equipped with a water pump pipe. The water pump pipe is connected to the pool cavity. The pipe opening on the side of the water pump away from the water pump is located near the bottom of the pool cavity.

[0012] A water supply pipe is provided at the top of the filter cylinder, and the water supply pipe extends into the pool cavity on the side away from the filter cylinder. The filter cylinder is provided with a first filter screen located between the water supply pipe and the water pump.

[0013] By adopting the above technical solution, during the fishpond bottom modification, the installation frame is first moved upward by the lifting component, creating a gap between the installation frame and the pond body. Then, a water pump draws water from the pond, carrying organic matter from the bottom of the fishpond into the filter bucket, which then passes through the first filter screen and returns to the pond cavity. Furthermore, during cleaning, an intercepting net traps the fish, reducing the possibility of injury caused by the suction force of the water pipe during the bottom modification. Simultaneously, the intercepting net reduces the likelihood of fish mixing with the organic matter at the bottom of the pond, preventing the organic matter from spreading and affecting water quality.

[0014] Optionally, the lifting assembly includes a lifting motor and a lifting shaft;

[0015] The lifting motor is installed inside the pool body and located below the pool cavity;

[0016] The lifting shaft is connected to the lifting motor, the lifting shaft is rotatably connected to the pool body, and the lifting shaft protrudes vertically into the pool cavity;

[0017] The outer periphery of the lifting shaft is provided with a threaded part and a blank part, the blank part is located above the threaded part, and the threaded part is threadedly connected to one of the support columns.

[0018] By adopting the above technical solution, the lifting motor rotates, and the lifting shaft drives the mounting frame to move upward until the support frame is rotatably connected to the blank part. At this time, the mounting frame is in a stationary state, thus intercepting the fish.

[0019] Optionally, the lifting shaft includes a bushing and a shaft body, the shaft body is rotatably connected to the lifting motor, and the bushing is sleeved on the outer periphery of the shaft body and rotatably connected to the pool body;

[0020] The bottom of the bushing is rotatably connected to the outer wall of the lifting motor. A linkage block is provided on the outer periphery of the bushing, and a linkage groove is formed on the inner wall of the bushing for the linkage block to slide up and down.

[0021] By adopting the above technical solution, the bushing abuts against the lifting motor, reducing the possibility that the force acting directly on the shaft may affect the use of the lifting motor.

[0022] Optionally, a rotating sleeve is provided on the outer periphery of the lifting shaft, and multiple stirring blades are evenly spaced along the circumferential direction on the outer periphery of the rotating sleeve, with the stirring blades located below the support column.

[0023] By adopting the above technical solution, the stirring blades agitate the pond body, thereby improving the effect of bottom improvement in fish ponds.

[0024] Optionally, the rotating sleeve is rotatably mounted on the lifting shaft, a pushing block is provided on the outer periphery of the lifting shaft, and the rotating sleeve is formed with a pushing hole for the pushing block to slide up and down;

[0025] The pool body has a receiving groove for accommodating the rotating sleeve and the stirring blade. A pushing column is provided on the top of the rotating sleeve. When the mounting frame abuts against the bottom cavity wall of the pool cavity, the supporting column pushes the pushing column downward until the rotating sleeve slides into the receiving groove.

[0026] A push spring is sleeved on the outer periphery of the lifting shaft;

[0027] When the pushing hole and the pushing block are aligned with each other, the pushing spring pushes the rotating sleeve to slide upward into the pool cavity, at which time the pushing block slides into the pushing hole.

[0028] By adopting the above technical solution, the rotating sleeve and the stirring blade are housed in the receiving tank, which is beneficial to make full use of the space in the pool cavity.

[0029] Optionally, the stirring blade includes a blade sleeve and a blade body, the blade sleeve being disposed on the outer periphery of the rotating sleeve, and the blade body sliding up and down on the blade sleeve;

[0030] When the rotating sleeve rotates, the bottom of the blade body slides into contact with the bottom wall of the pool cavity.

[0031] By adopting the above technical solution, the blades come into contact with the bottom of the pool cavity, thereby improving the stirring effect of the stirring blades.

[0032] Optionally, the pool body has a sealing plate that slides up and down to block the receiving groove, the bottom of the rotating sleeve is rotatably connected to the top of the sealing plate, and the top of the push spring abuts against the bottom of the sealing plate;

[0033] The sealing plate is provided with a limiting block on its side wall, and the receiving groove is formed with a limiting groove for the limiting block to slide up and down. When the limiting block abuts against the top groove wall of the limiting groove, the top end face of the sealing plate and the bottom cavity wall of the pool cavity are on the same plane.

[0034] By adopting the above technical solution, the sealing plate seals the receiving tank, reducing the amount of organic matter deposited during bottom modification from falling into the receiving tank.

[0035] Optionally, a mounting groove is formed relative to the inner wall of the mounting frame, and the mounting frame is rotatably connected to a winding shaft located in the mounting groove, the winding shaft being parallel to the support column;

[0036] A second filter screen is wound around the outer periphery of the winding shaft;

[0037] The support column threadedly connected to the lifting shaft is equipped with a control component, and the support columns on both sides of the lifting shaft respectively form through openings for the second filter screen to pass through.

[0038] When the lifting shaft rotates and drives the mounting frame to move upward, the control component controls the second filter screen to pass through the through-hole and simultaneously abut against the opposite side of the same support column.

[0039] The winding shaft is wound with a coil spring. When the lifting shaft rotates and drives the mounting frame to move downward, the control component releases the second filter screen. At this time, the coil spring drives the winding shaft to wind the second filter screen.

[0040] By adopting the above technical solution, the second filter screen can intercept organic matter from scattering when the fish pond bottom is modified.

[0041] Optionally, the control component includes a control sleeve, a connecting sleeve, a control rope, control teeth, and sliding teeth;

[0042] The connecting sleeve is fitted onto the outer periphery of the lifting shaft, and a connecting block is provided on the inner wall of the connecting sleeve. A connecting groove is formed on the outer periphery of the lifting shaft for the connecting block to slide up and down.

[0043] The control sleeve is rotatably sleeved on the outer periphery of the connecting sleeve and rotatably connected to the support column. There are multiple control ropes, which are respectively wrapped around the outer periphery of the rotating sleeve. The end of the control rope away from the control sleeve is respectively connected to the second filter screen on both sides.

[0044] The sliding teeth are multiple and evenly spaced along the circumference on the inner circumferential sidewall of the control sleeve, and the control teeth are disposed on the outer circumferential side of the connecting sleeve, and the control teeth mesh with the sliding teeth;

[0045] When the mounting frame moves upward, the control tooth abuts against the sliding tooth. At this time, the control sleeve rotates and wraps around the control rope, causing the second filter screen to move toward the lifting shaft until the second filter screen abuts against the support column. Then, the control tooth is slidably connected to the sliding tooth.

[0046] When the mounting frame moves downward, the sliding tooth supports the control tooth in one direction, and at this time the control sleeve reverses to release the control rope.

[0047] By adopting the above technical solution, during the upward movement of the installation frame, the lifting shaft drives the rotating sleeve to rotate, causing the rotating sleeve to wrap around the control rope. The control rope pulls the second interception net to cover the installation space, eliminating the need for additional power to pull the interception net.

[0048] Secondly, this application provides a high-temperature fish harvesting method, which adopts the following technical solution:

[0049] A method for catching fish at high temperatures includes the following steps:

[0050] S1: During the first 15-20 days, the installation frame is controlled to move upward by activating the lifting component, and then the organic matter deposited at the bottom of the pond is extracted by the water pump to improve the bottom of the fish pond;

[0051] S2: Test the water quality every other day after the fish pond bottom is modified;

[0052] S3: The fish pond bottom was modified again after the organic matter in the pond water exceeded the standard;

[0053] S4: Apply anti-stress medication to the entire pond 3-5 hours before harvesting the fish, and then use a net to harvest them.

[0054] By adopting the above technical solutions, the bottom of the fishpond is modified before the fish are harvested, which purifies the water quality, improves the purity of the fish, and reduces the possibility of bone disease.

[0055] In summary, this application includes at least one of the following beneficial effects:

[0056] 1. When modifying the bottom of a fishpond, using a net to intercept the fish reduces the possibility of injury caused by the suction of the water pipe. At the same time, the net also reduces the likelihood of the fish stirring up organic matter at the bottom of the pond, thus minimizing the possibility of this organic matter spreading and affecting water quality.

[0057] 2. The stirring blades agitate the water, increasing the speed and effectiveness of bottom improvement in the pool. The second filter screen intercepts organic matter at the bottom of the pool, reducing the possibility of organic matter spreading. Attached Figure Description

[0066] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0067] This application discloses a fishpond with a bottom-modifying system. See also... Figure 1 The fish pond includes a pond body 1, which has a cylindrical structure. A pond cavity 11 is formed in the middle of the pond body 1 for fish farming.

[0068] See Figure 1 and Figure 2 The fish pond also includes a filter cylinder 5, which is fixedly installed on the outer wall of the pond body 1 and rests against the ground. A filter chamber is formed inside the filter cylinder 5, and a water pump 51 is installed in the filter cylinder 5, fixedly installed on the bottom wall of the filter chamber. The water pump 51 is fixedly connected to a water suction pipe 52, which is fixedly connected to the pond body 1 and communicates with the pond chamber 11. The opening of the water suction pipe 52 on the side away from the water pump 51 is located near the bottom of the pond chamber 11. When the water pump 51 is started, the water suction pipe 52 draws water from the bottom of the pond body 1. This water flow carries organic matter deposited at the bottom of the pond into the filter chamber, thus improving the bottom condition of the pond.

[0069] A water supply pipe 53 is fixedly connected to the top of the filter cylinder 5, and the water supply pipe 53 extends into the pool cavity 11 from the side away from the filter cylinder 5. A first filter screen 54 is fixedly installed on the filter cylinder 5 between the water supply pipe 53 and the water pump 51. When the water level in the pool cavity rises, the first filter screen 54 filters the pool water, and then the filtered pool water flows back into the pool cavity 11 under pressure through the water supply pipe 53. The filter cylinder 5 is equipped with a detachable and fixed pool cover. When the amount of organic matter filtered in the filter cavity is large, the pool cover can be removed to clean the filter cavity.

[0070] The fishpond also includes a mounting frame 2, which is installed inside the pond cavity 11. The outer peripheral wall of the mounting frame 2 slides and contacts the peripheral wall of the pond cavity 11, creating friction. A square support hole 21 is formed in the center of the mounting frame 2. Support columns 3 are fixedly connected to the mounting frame 2, located within the support hole 21. The length of the support columns 3 is parallel to one side wall of the support hole 21, and multiple support columns 3 are evenly spaced. The support columns 3 and the mounting frame 2 cooperate to form an installation space 22. A guide surface is formed on the top of the mounting frame 2 to guide sediment to slide into the installation space 22.

[0071] See Figure 1 and Figure 3 The fish pond also includes an interception net 23 and a lifting assembly 4. The interception net 23 is made of stainless steel and is used to intercept fish. The interception nets 23 are located in the installation space 22 and correspond one-to-one. The periphery of the interception net 23 is fixedly connected to the side wall of the installation space 22.

[0072] A lifting assembly 4 is disposed in the pool body 1. The lifting assembly 4 includes a lifting motor 41 and a lifting shaft 42. The lifting motor 41 is fixedly installed inside the pool body 1 and located directly below the pool cavity 11. The lifting shaft 42 includes a bushing 421 and a shaft body 422. The shaft body 422 is rotatably connected to the lifting motor 41, and the bushing 421 is fitted onto the outer periphery of the shaft body 422 and is rotatably connected thereto. A linkage block 425 is fixedly connected to the outer periphery of the shaft body 422. A linkage groove 426 extending vertically is formed on the inner periphery of the bushing 421. The linkage block 425 slides up and down in the linkage groove 426, thereby creating a linkage between the bushing 421 and the shaft body 422. When the lifting motor 41 is started, the shaft body 422 drives the bushing 421 to rotate. The bottom of the bushing 421 makes rotatable contact with the outer wall of the lifting motor 41, and the bushing 421 is rotatably connected to the pool body 1. The bushing 421 has a blank portion 424 and a threaded portion 423 on its outer peripheral sidewall, with the blank portion 424 located directly above the threaded portion 423. The threaded portion 423 is threadedly connected to the support column 3 located in the middle position, and the threaded connection is located in the middle position of the support column 3.

[0073] When the lifting motor 41 drives the bushing 421 to rotate forward, the friction between the mounting frame 2 and the pool wall of the pool body 1 restricts the rotation of the mounting frame 2. At the same time, the support column 3 drives the mounting frame 2 to move upward until the support column 3 is aligned with the blank part 424. At this time, the rotating sleeve 6 rotates freely, and the mounting frame 2 stops rising. At this time, the intercepting net 23 intercepts the fish, reducing the possibility of fish being attracted and injured when the water pumping pipe 52 draws water from the pool. When the lifting motor 41 drives the bushing 421 to rotate in reverse, under the action of gravity, when the support column 3 is threadedly connected to the threaded part 423, the mounting frame 2 moves downward until the mounting frame 2 abuts against the bottom cavity wall of the pool cavity 11, and the lifting motor 41 stops rotating.

[0074] See Figure 4The mounting frame 2 has mounting grooves 24 formed on its two inner walls. Two winding shafts 25 are rotatably connected to the mounting frame 2 within the mounting grooves 24, each corresponding to one of the mounting grooves 24. The winding shafts 25 are parallel to the support columns 3. The mounting frame 2 is equipped with a second filter screen 26, one end of which is fixed to the winding shaft 25. A coil spring 27 is wound around the outer periphery of the winding shaft 25, one end of which is engaged with the winding shaft 25, and the other end is engaged and fixed to the mounting frame 2. In the initial state, the coil spring 27 is released elastically, driving the winding shaft 25 to rotate, causing the second filter screen 26 to wind around the outer periphery of the winding shaft 25.

[0075] See Figure 3 and Figure 4 The middle support column 3 is equipped with a control component, and the support columns 3 on both sides of the lifting shaft 42 respectively form through-holes 31 for the second filter screen 26 to pass through (the through-holes 31 are located in...). Figure 2 (Selected from the list). When the lifting shaft 42 rotates forward and drives the mounting frame 2 to move upward, the control component controls the two opposing second filter screens 26 to pass through the through-hole 31 until the ends of the two second filter screens 26 away from the winding shaft 25 simultaneously abut against the opposite sidewalls of the support column 3 located in the middle. At this time, the coil spring 27 enters the winding state. At the same time, when the lifting shaft 42 rotates in reverse and drives the mounting frame 2 to move downward, the control component releases the second filter screens 26, causing the coil spring 27 to elastically release, driving the winding shaft 25 to rotate and wind the second filter screens 26.

[0076] See Figure 3 and Figure 5 The control assembly includes a control sleeve 71, a connecting sleeve 72, a control rope 73, a control tooth 7, and a sliding tooth 74. The connecting sleeve 72 is rotatably sleeved on the outer periphery of the lifting shaft 42 and rotatably connected to the support column 3 located in the middle. A connecting block 721 is fixedly connected to the inner wall of the connecting sleeve 72. A connecting groove 427 extending vertically is formed on the outer periphery of the shaft sleeve 421. The connecting block 721 slides up and down in the connecting groove 427, so that the shaft sleeve 421 can drive the connecting sleeve 72 to rotate through the connecting block 721, and the connecting sleeve 72 can slide up and down on the shaft sleeve 421. The support column 3 located in the middle is threaded to the threaded part 423 on the bushing 421, which is located directly above the connecting sleeve 72. At the same time, although the thread of the threaded part 423 is interrupted by the connecting groove 427, the threads on both sides of the connecting groove 427 are in a continuous state because the connecting groove 427 extends in the vertical direction. Therefore, the support column 3 and the threaded part 423 are still in a threaded state. When the bushing 421 rotates, the mounting frame 2 can move up and down.

[0077] See Figure 4 and Figure 5The control sleeve 71 is rotatably fitted onto the outer periphery of the connecting sleeve 72 and rotatably mounted within the support column 3 located in the middle. There are two sets of control ropes 73, each set corresponding to a second filter screen 26. Each set of control ropes 73 has two ropes, each wound around the outer periphery of the control sleeve 71. One end of each control rope 73 is fixed to the outer periphery of the control sleeve 71, and the other end is connected to the side wall of the second filter screen 26 away from the winding shaft 25. The connection points between the control rope 73 and the second filter screen 26 are located near the opposite side walls of the second filter screen 26. Simultaneously, the control rope 73 runs along the support hole 21 (the support hole 21 is located in...). Figure 1 The control rope 73 extends through the support column 3 and through the hole wall until it reaches the support column 3 in the middle position. The control rope 73 then extends along the length of the support column 3 to the control sleeve 71. The second filter screen 26 has fine mesh to intercept organic matter deposited in the pond water, reducing the possibility of organic matter deposited at the bottom of the pond flowing upwards due to water flow during pond bottom improvement. To facilitate the control sleeve 71 winding the control rope 73, the second filter screens 26 and coil springs 27 on both sides are staggered. That is, one second filter screen 26 is pulled out from above the winding shaft 25, and the other second filter screen 26 is pulled out from below the winding shaft 25. Correspondingly, the coil springs 27 on both sides are staggered, allowing the coil springs 27 on both sides to drive the corresponding winding shafts 25 to wind the second filter screen 26.

[0078] Multiple sliding teeth 74 are fixed to the inner circumferential sidewall of the control sleeve 71 at even intervals along the circumference, and multiple control teeth 7 are fixed to the outer circumferential side of the connecting sleeve 72 at even intervals along the circumference. The control teeth 7 mesh with the sliding teeth 74. The control teeth 7 and the sliding teeth 74 each adopt a triangular tooth structure and are made of elastic stainless steel.

[0079] When the bushing 421 rotates clockwise, causing the mounting frame 2 to move upward, the control tooth 7 first abuts against the sliding tooth 74. At this time, the connecting sleeve 72 drives the control sleeve 71 to rotate, winding the control rope 73 and causing the two second filter screens 26 on both sides to move towards the lifting shaft 42. When the two second filter screens 26 simultaneously abut against the opposite side walls of the support column 3 located in the middle, the connecting sleeve 72 continues to rotate. At this time, the control tooth 7 is slidably connected to the sliding tooth 74, and the connecting sleeve 72 is in an idle state, allowing the bushing 421 to continue rotating clockwise. When the bushing 421 rotates counterclockwise, causing the mounting frame 2 to move downward, the sliding tooth 74 supports the control tooth 7 in one direction, and the control sleeve 71 rotates counterclockwise to release the control rope 73, allowing the winding shaft 25 to wind the second filter screens 26.

[0080] See Figure 3A rotating sleeve 6 is rotatably sleeved on the outer periphery of the bushing 421, and a push block 61 is fixedly connected to the outer periphery of the bushing 421. A push hole 62 is formed on the inner periphery of the rotating sleeve 6 for extending in the vertical direction. The push hole 62 of the push block 61 slides up and down, so that the bushing 421 and the rotating sleeve 6 can be linked together.

[0081] See Figure 3 Multiple stirring blades 65 are evenly spaced along the circumferential side of the rotating sleeve 6, and are located below the support column 3. Each stirring blade 65 includes a blade sleeve 651 and a blade body 652. The blade sleeve 651 is fixed to the outer circumference of the rotating sleeve 6, and its width is less than the thickness of the rotating sleeve 6. The blade body 652 slides up and down on the blade sleeve 651 and can protrude downwards beyond the blade sleeve 651 under gravity. A stop block is fixedly connected to the blade body 652, and a groove is formed in the blade sleeve 651. The stop block slides up and down within the groove, preventing the blade body 652 from detaching from the blade sleeve 651.

[0082] When the rotating sleeve 6 is located inside the pool cavity 11 and the rotating sleeve 6 rotates, the bottom of the blade 652 slides into contact with the bottom wall of the pool cavity 11. At this time, the blade 652 moves the bottom of the pool, further accelerating the bottom modification speed of the fish pond and improving the cleaning effect of the bottom of the fish pond.

[0083] See Figure 6 and Figure 7 The bottom wall of the pool cavity 11 has a receiving groove 12, the shape of which is adapted to the rotating sleeve 6 and the stirring blade 65. A sealing plate 66 is provided in the pool body 1, the shape of which is adapted to the shape of the opening of the receiving groove 12. The sealing plate 66 slides up and down on the outer periphery of the rotating sleeve, and is located directly below the bushing 421 and the stirring blade 65. A limiting block 661 is fixedly connected to the side wall of the sealing plate 66. A limiting groove 662 extending vertically is formed in the wall of the receiving groove 12. The limiting block 661 slides up and down in the limiting groove 662 to prevent the sealing plate 66 from disengaging from the receiving groove 12. A pushing spring 64 is sleeved on the outer periphery of the bushing 421. The top of the pushing spring 64 abuts against the bottom of the sealing plate 66, and the bottom of the pushing spring 64 abuts against the outer wall of the lifting motor 41. When the spring 64 is released elastically, it pushes the sealing plate 66 to move upward. At this time, the sealing plate 66 pushes the rotating sleeve 6 to move upward until the top of the limiting block 661 abuts against the top wall of the limiting groove 662. At this time, the top end face of the sealing plate 66 is on the same plane as the bottom wall of the pool cavity 11. At this time, the sealing plate 66 blocks the receiving groove 12, restricting the organic matter at the bottom of the pool from falling into the receiving groove 12. At the same time, the rotating sleeve 6 and the stirring blade 65 are in the pool cavity 11, so that the stirring blade 65 can stir the bottom of the pool.

[0084] See Figure 2 and Figure 3A push column 63 is fixedly connected to the top of the rotating sleeve 6, and the push column 63 is aligned with the support column 3 located in the middle. When the mounting frame 2 moves downward, the support column 3 first abuts against the push column 63; then the push column 63 pushes the rotating sleeve 6 downward, causing the push block 61 to disengage from the push hole 62, and the rotating sleeve 6 rotates under the action of inertial force; then the rotating sleeve 6 first pushes the sealing plate 66 downward, causing the sealing plate 66 to slide into the receiving groove 12; while the blade 652 first slides into the blade sleeve 651, and then when the blade 652 is aligned with the groove opening of the receiving groove 12, under the action of gravity, the blade 652 slides out of the blade sleeve 651 and inserts into the receiving groove, at which point the rotating sleeve 6 stops rotating; finally, the mounting frame 2 continues to move downward until the mounting frame 2 abuts against the bottom of the pool cavity 11, and the rotating sleeve 6 and the stirring blade 65 completely slide into the receiving groove 12.

[0085] The implementation principle of a fishpond with a bottom-modification system according to an embodiment of this application is as follows:

[0086] During the bottom modification of the fishpond, the lifting motor 41 and the water pump 51 are started. Then, the mounting frame 2 moves upward, and the second filter screen 26 slides to abut against the side wall of the support column 3 located in the middle position. Then, the rotating sleeve 6 and the stirring blade slide into the pond cavity 11 and rotate to stir the bottom of the pond. At the same time, the water pump 51 draws pond water and returns it to the pond cavity 11 after passing through the first filter screen 54. When the bottom modification is completed, the lifting motor 41 reverses, driving the mounting frame 2 to move downward. At the same time, the second filter screen 26 winds back around the outer periphery of the winding shaft 25, and the stirring blade 65 and the rotating sleeve 6 slide into the receiving groove 12.

[0087] On the other hand, this application discloses a method for high-temperature fish harvesting, including the following steps:

[0088] Step 1: During the first 15-20 days, the installation frame 2 is moved upward by starting the lifting component 4. Then, the organic matter deposited at the bottom of the pond is extracted by the water pump 51 to improve the bottom of the fish pond.

[0089] Step 2: Test the water quality every other day after modifying the bottom of the fish pond;
