Description

Technical Field

[0001] This invention relates to the field of aquaculture, and more specifically to an aquaculture system based on diatomaceous earth boards. Background Technology

[0002] As is well known, diatomaceous earth boards have formaldehyde-removing and antibacterial functions, so they are usually installed on the side walls of aquaculture areas. They effectively inhibit the growth of harmful microorganisms and pathogens in the water, reducing the risk of disease caused by bacterial infections in aquatic products and thus improving their survival rate. In aquaculture systems, aerators are also installed in the aquaculture areas to increase the oxygen content in the water.

[0003] For example, Chinese patent document CN118476505A, published on August 13, 2024, entitled "An Aerator", includes an impeller-type aerator and a waterwheel-type aerator. The aerator operates by floating on the water surface using a floating mechanism. The buoyancy generated by the floating mechanism makes the impeller's water depth shallower than the actual water depth during operation. The aerator is equipped with a water receiving container. After the aerator starts, the water it raises falls into the water receiving container, causing the aerator to sink to a set position. The water in the water receiving container will automatically overflow, preventing the aerator from sinking further. After the machine stops, the water in the water receiving container will be discharged from the drainage hole at the bottom, causing the aerator to float up and reducing the impeller's water depth, making it easier to start up next time.

[0004] The shortcomings of the aforementioned existing technology are that during the initial startup of the aerator, part of the impeller still needs to be placed in the water. Obviously, this will cause the following problems during the startup of the aerator: firstly, it will still be subject to the resistance of some water bodies; secondly, the impeller part placed in the water will be immersed for a long time, and its surface is prone to the growth of moss and other organisms, which will increase the resistance when the impeller rotates. Summary of the Invention

[0005] The purpose of this invention is to provide an aquaculture system based on diatomaceous earth boards to overcome the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Aquaculture system based on diatomaceous earth panels includes a power mechanism for agitating water and a floating mechanism for making the power mechanism float on the water.

[0008] The floating mechanism includes a float ball, which has a water inlet that is placed in the water body;

[0009] When the power mechanism is stopped, the power mechanism is positioned above the water body;

[0010] It also includes a sealing component, which controls the opening and closing of the inlet based on the rotation state of the power mechanism.

[0011] The aforementioned aquaculture system based on diatomaceous earth boards has multiple water inlets.

[0012] The aforementioned aquaculture system based on diatomaceous earth boards includes a buoy with an internal cavity, a sealing element slidably disposed within the cavity, and a drive assembly for driving the sealing element to reciprocate.

[0013] In the aforementioned aquaculture system based on diatomaceous earth boards, the drive assembly includes a telescopic rod fixed to the power mechanism, a first elastic element is provided inside the telescopic rod, a spherical part is provided at the end of the telescopic rod, a transmission rod is fixed to the sealing member, and an abutment part is provided on the transmission rod.

[0014] When the telescopic rod extends, the abutting part is located on the travel stroke of the spherical part.

[0015] In the aforementioned aquaculture system based on diatomaceous earth boards, a second elastic element is provided between the sealing element and the receiving cavity.

[0016] In the aforementioned aquaculture system based on diatomaceous earth boards, the top of the sealing component is provided with an arc-shaped surface.

[0017] In the aforementioned aquaculture system based on diatomaceous earth boards, a connecting rod is provided on the power mechanism, and an anti-reverse component is provided between the connecting rod and the transmission rod to prevent the transmission rod from moving upward.

[0018] In the aforementioned aquaculture system based on diatomaceous earth boards, the anti-reverse component includes a locking plate disposed on the transmission rod, and a locking block elastically disposed on the connecting rod, the locking block engaging with the locking plate.

[0019] In the aforementioned aquaculture system based on diatomaceous earth boards, the card block is provided with an arc-shaped strip, and the telescopic rod is provided with an arc-shaped part;

[0020] When the power mechanism stops, the arc-shaped portion abuts against the arc-shaped strip.

[0021] The aforementioned aquaculture system based on diatomaceous earth boards also includes a rotating base, a diagonal rod on the power mechanism, and a sliding sleeve inside the rotating base, with the diagonal rod slidably connected to the sliding sleeve.

[0022] In the above technical solution, the aquaculture system based on diatomaceous earth provided by the present invention, when the aerator is stopped, controls the power unit to be completely above the water body through the float mechanism, that is, the power unit will not be in contact with the water body at this time, and the sealing component will block the water inlet. When the speed of the power unit increases to the working state, the sealing component is controlled to open the water inlet, and water will enter the float from the water inlet to increase the gravity of the aerator, thereby increasing its water depth to realize the subsequent oxygenation process. The advantage of this setting is that since the power unit is completely above the water body when it is stopped, the resistance when the power unit starts is reduced, and the power unit will not be submerged in water when it is stopped.

Therefore, they should not be construed as limiting the present invention.

[0035] Reference Figure 1-7 The aquaculture system based on diatomaceous earth provided in this embodiment of the invention includes a power mechanism for agitating water and a floating mechanism for making the power mechanism float on the water.

[0036] The floating mechanism includes a float 4, and the float 4 has a water inlet 5 that is placed in the water.

[0037] When the power mechanism is stopped, the power mechanism is positioned above the water body;

[0038] It also includes a sealing component 6, which controls the opening and closing of the water inlet 5 based on the rotation state of the power mechanism.

[0039] Specifically, the aquaculture system includes a pool to provide a growth environment for aquatic products. The inner walls of the pool are lined with diatomaceous earth panels. To increase the dissolved oxygen level in the pool, an aerator is typically installed. The aerator includes a power unit and a floating mechanism connected to the power unit. The power unit includes a motor 2 and an impeller 3 connected to the output of the motor 2. The floating mechanism includes three floats 4, all connected to the power unit. The buoyancy provided by the three floats 4 allows the power unit to float on the water surface. During operation, the motor 2 drives the impeller 3 to rotate, thereby increasing the dissolved oxygen level in the pool. The water in the pool surges upwards to increase the dissolved oxygen content. To reduce the torque when the motor 2 starts, only a portion of the impeller 3 is inserted into the water in the initial working state of the power mechanism. A water-receiving container is provided on the float 4. When the impeller 3 rotates, it lifts the water, and some water falls into the water-receiving container, increasing the overall weight of the device and thus gradually increasing the device's immersion depth. This is existing technology and will not be elaborated further; please refer to the patent document with publication number CN118476505A for details. One of the core innovations of this invention is that the float 4 is preferably ellipsoidal. (Its ends are hemispherical, and its middle is cylindrical), its interior is hollow. The sealing component 6 can be an existing opening and closing structure such as an electric valve. A speed sensor for sensing the rotation speed of the impeller 3 is installed on the output shaft of the power mechanism. The purpose of this arrangement is that when the aerator is stopped, the floating mechanism controls the power mechanism to be completely above the water body, that is, the power mechanism will not be in contact with the water body at this time, and the sealing component 6 will block the inlet 5. When it is necessary to aerate the pool, the motor 2 is started, and the motor 2 drives the impeller 3 to rotate. When the speed sensor senses the rotation speed of the impeller 3... After the rotation speed is increased to the working state, the control sealing component 6 opens the water inlet 5. At this time, water will enter the float 4 from the water inlet 5, thereby increasing the water depth of the aerator to realize the subsequent oxygenation process. The advantage of this setting is that since the power mechanism is completely above the water when it is stopped, the resistance when the power mechanism starts is reduced, and the power mechanism is not submerged in water when it is stopped. Moreover, by overflowing into the float 4, the water intake speed of the three floats 4 can be kept almost the same, so as to avoid the aerator from tipping over as much as possible.

[0040] Preferably, multiple water inlets 5 are provided. Specifically, for a single float 4, multiple water inlets 5 are provided, and the multiple water inlets 5 are arranged in an array on the surface of the float 4 to improve the water inlet and outlet speed inside the receiving cavity 7.

[0041] Preferably, the float 4 has an internal cavity 7, and the sealing member 6 is slidably disposed within the cavity 7. It also includes a drive assembly for driving the sealing member 6 to reciprocate. Specifically, the float 4 is divided into an upper first part 401 and a lower second part 402. The first part 401 has a sealed cavity, the cavity 7 is disposed within the second part 402, and the inlet 5 is located on the side wall of the cavity 7. The sealing member 6 is an inverted cylindrical shape, with its outer diameter matching the inner diameter of the cavity 7. The drive assembly can be an existing linear drive structure such as an electric push rod. This arrangement allows the sealing member 6 to simultaneously block multiple inlets 5 when they are at the same height as the inlet 5, and to open the inlet 5 when needed (i.e., when the inlet 5 needs to be opened). (That is, at this time, the speed sensor senses that the impeller 3 is in working condition) and controls the sealing part 6 to move downward through the drive component. At this time, the water inlet 5 connects the water tank and the receiving cavity 7. Since the water inlet 5 is located inside the water body, the water in the water tank will enter the receiving cavity 7 from multiple water inlets 5 at the same time, so that the impeller 3 sinks into the water body to realize the subsequent oxygenation process. After the oxygenation is completed, the sealing part 6 is controlled to move upward through the drive component, so that the water in the receiving cavity 7 can be pushed out from the water inlet 5, thereby causing the aerator to move upward as a whole, so as to lift the impeller 3 from the water tank to the top of the water tank for the next oxygenation.

[0042] As an alternative to the above-mentioned electric push rod and speed sensor used to control the lifting and lowering of the sealing member 6, preferably, the drive assembly includes a telescopic rod 8 fixed to the power mechanism, a first elastic element 9 is provided inside the telescopic rod 8, a spherical portion 10 is provided at the end of the telescopic rod 8, a transmission rod 11 is fixed to the sealing member 6, and an abutment portion 12 is provided on the transmission rod 11; when the telescopic rod 8 extends, the abutment portion 12 is located on the movement stroke of the spherical portion 10; a second elastic element 13 is provided between the sealing member 6 and the receiving cavity 7.Specifically, there are preferably three telescopic rods 8. One end of the telescopic rod 8 is fixed to the output shaft of the motor 2 and arranged radially along the output shaft. The spherical part 10 is fixed to the other end of the telescopic rod 8 and is preferably a solid metal structure. The telescopic rod 8 includes two ends that slide against each other. The first elastic element 9 is preferably a spring and is disposed inside the telescopic rod 8. The transmission rod 11 is preferably U-shaped, with one end penetrating through the first part 401 and extending into the receiving cavity 7, and is fixed to the sealing element 6 inside the receiving cavity 7. The abutment part 12 is disposed at the other end of the transmission rod 11. The abutment part 12 is preferably an arc-shaped block with the arc surface disposed on the top. The second elastic element 13 is similarly disposed at the other end. Preferably, a spring is used, with one end fixed to the inner bottom wall of the receiving cavity 7 and the other end abutting against the inner top wall of the sealing member 6. Under the action of the elastic force of the second elastic member 13, the sealing member 6 is positioned at its highest point, sealing the inlet 5. The purpose of this arrangement is that when the power mechanism is first started, the output shaft rotates at a relatively slow speed. At this time, under the action of the elastic force of the first elastic member 9, the rotation radius of the spherical part 10 is smaller than the distance from the arc-shaped part 20 to the output shaft. That is, at this time, the spherical part 10 will not contact the abutting part 12. As the rotation speed of the output shaft gradually increases, according to the formula for centrifugal force F=mω²r, the greater the rotational angular velocity of the output shaft, the greater the rotation radius of the spherical part 10. The greater the centrifugal force on the spherical part 10, the longer the telescopic rod 8 will extend. When the centrifugal force on the spherical part 10 is greater than the elastic force of the first elastic element 9, the telescopic rod 8 will extend and store force on the first elastic element 9, thereby gradually increasing the rotation radius of the spherical part 10. When the output shaft speed reaches its maximum value (i.e., the working state of the power mechanism), the telescopic rod 8 will also extend to its maximum value. At this time, the arc-shaped surface of the abutment part 12 is located on the movement stroke of the spherical part 10, so that the spherical part 10 abuts against the arc-shaped surface of the abutment part 12, causing the abutment part 12 to move downward. Under the action of the transmission rod 11, the sealing member 6 will move downward. The aerator moves downward and stores force on the second elastic element 13 to passively open the inlet 5. Water enters the receiving cavity 7 through the inlet 5, causing the aerator to sink. When the aerator stops, the speed of the motor 2 output gradually decreases, thereby reducing the centrifugal force on the spherical part 10. When the centrifugal force is less than the elastic force of the first elastic element 9, the telescopic rod 8 shortens, causing the spherical part 10 to move away from the contact part 12. At this time, the elastic force of the second elastic element 13 is released, causing the sealing element 6 to move upward, allowing the water in the receiving cavity 7 to be passively discharged from the inlet 5, so that the aerator moves upward passively in preparation for the next aeration.

[0043] Preferably, the top of the sealing member 6 is provided with an arc-shaped surface. Specifically, the bottom of the first part 401 is provided with an arc-shaped surface adapted to the sealing member 6, and the middle part of the arc-shaped surface is higher than its edge part, so as to facilitate the drainage of water from the receiving cavity 7.

[0044] It should be noted that, due to the limited number of spherical parts 10, there will be a period of time during the rotation of two adjacent spherical parts 10 that cannot abut against the contact part 12. This causes a portion of the elastic force of the second elastic element 13 to be released, causing the aerator to move upward a certain distance. This repeated movement will cause the aerator to shake up and down. To solve the above problem, a connecting rod 14 is further provided on the power mechanism, and an anti-reverse component is provided between the connecting rod 14 and the transmission rod 11 to prevent the transmission rod 11 from moving upward. Specifically, there are preferably three connecting rods 14, so that the three floats 4 are connected to the power mechanism through the three connecting rods 14. The anti-reverse assembly can be a cylinder and pin shaft mating structure set on the connecting rod 14. Correspondingly, the transmission rod 11 is provided with a pin hole adapted to the pin shaft. The purpose of this arrangement is that when the water tank is oxygenated, the sealing part 6 moves down to the lowest position through the abutting action of the spherical part 10 and the abutting part 12. At this time, the pin shaft is inserted into the pin hole by the electric push rod to lock the position of the transmission rod 11 and the sealing part 6, so that the aerator is maintained in a stable position, thereby improving the stability of the aerator during operation.

[0045] As an alternative to the above-mentioned electric push rod cooperating with the pin shaft and pin hole to lock the sealing component 6, preferably, the anti-reverse assembly includes a locking plate 15 disposed on the transmission rod 11, and a locking block 16 elastically disposed on the connecting rod 14, the locking block 16 engaging with the locking plate 15. Specifically, the clamping plate 15 is disposed on the side wall of the transmission rod 11, and the cross-section of each tooth is preferably a right-angled triangle. The clamping block 16 is preferably a wedge-shaped block. A groove 17 is provided on the bottom wall of the connecting rod 14. An elastic element 18 is provided between the clamping block 16 and the groove 17, and the third elastic element 18 is also preferably a spring. The purpose of this arrangement is that during the process of the spherical part 10 abutting the abutting part 12 to drive the transmission rod 11 and the sealing member 6 to move downward, the inclined surface of the clamping plate 15 abuts against the wedge-shaped surface of the clamping block 16, so that the wedge-shaped block avoids and stores force on the third elastic element 18. After the inclined surface of the tooth abuts against the wedge-shaped surface of the clamping block 16, the third elastic element 18 releases force. The elasticity is released so that the locking block 16 is inserted into the gap of the next tooth. At this time, the horizontal surface of the wedge block abuts against the horizontal surface of the tooth, so that the transmission rod 11 cannot move upward, thereby fixing the position of the sealing member 6. It should be noted that when the spherical part 10 abuts against the abutting part 12, due to inertia, the abutting part 12 will move downward further by about one tooth distance. At this time, the locking block 16 will engage with the tooth, so that the abutting part 12 is fixed below the spherical part 10. This achieves passive locking of the sealing member 6, so as to prevent the spherical part 10 from abutting against the abutting part 12 during the rotation of the output shaft, thereby minimizing the risk of damage to the spherical part 10 and the abutting part 12.

[0046] Furthermore, the locking block 16 is provided with an arc-shaped strip 19, and the telescopic rod 8 is provided with an arc-shaped portion 20; when the power mechanism stops, the arc-shaped portion 20 abuts against the arc-shaped strip 19. Specifically, three arc-shaped strips 19 are provided, and the three arc-shaped strips 19 are respectively fixed to the bottom end of the three locking blocks 16, forming a circle between the three locking blocks 16. The elastic force of the first elastic member 9 is greater than the elastic force of the third elastic member 18. The arc-shaped portion 20 is located on the side of the spherical portion 10 away from the abutment portion 12. The purpose of this arrangement is that when the aerator stops, the arc-shaped portion 20 abuts against the outer peripheral surface of the arc-shaped strip 19. Under the action of the elastic force of the first elastic member 9, the locking block 16 is limited to a position away from the locking plate 15 by the arc-shaped strip 19. When the booster is working, the telescopic rod 8 extends to move the arc-shaped portion 20 away from the arc-shaped strip 19. At this time, the elastic force of the third elastic element 18 is released, so as to drive the arc-shaped strip 19 and the locking block 16 to move synchronously away from the central axis of the output end, so that the locking block 16 engages with the locking plate 15, thereby achieving passive locking of the transmission rod 11 and the sealing component 6. When the booster stops, the telescopic rod 8 is shortened, so that the arc-shaped part 20 abuts against the outer peripheral surface of the arc-shaped strip 19. Since the elastic force of the first elastic element 9 is greater than the elastic force of the third elastic element 18, it will drive the arc-shaped strip 19 to move in the opposite direction, so that the locking block 16 moves away from the locking plate 15, and stores force on the third elastic element 18, thereby achieving passive unlocking of the transmission rod 11 and the sealing component 6.

[0047] In another embodiment of the present invention, a rotating seat 21 is also included. A diagonal rod 24 is provided on the power mechanism, and a sliding sleeve 22 is provided inside the rotating seat 21. The diagonal rod 24 and the sliding sleeve 22 are slidably connected. Specifically, the rotating seat 21 is preferably a bearing, which is fixed above the water tank by a crossbar or other structure. One end of the diagonal rod 24 is fixed to the upper part of the power mechanism housing 1, and the other end is provided with a vertical section 23. The vertical section 23 is slidably connected to the sliding sleeve 22, and a limiting structure such as a limit strip is provided between them to prevent mutual rotation. The purpose of this arrangement is that, during the operation of the aerator, power can be provided by a drive source such as a reduction motor (not shown), causing the diagonal rod 24 and the aerator to rotate around the central axis of the rotating seat 21, thereby increasing the working range of the aerator. Furthermore, during the process of the float 4 driving the aerator to rise and fall, the vertical section 23 will slide vertically relative to the sliding sleeve 22 for adaptation.

[0048] As an alternative to the aforementioned reduction motor 2 driving the aerator to rotate around the central axis of the rotating base 21, the power mechanism is arranged at an angle. Specifically, the path of the aerator's rotation around the rotating base 21 forms a virtual circle, and the power mechanism is arranged at an angle, that is, the power mechanism is inclined along the direction of the tangent of the virtual circle, and the inclination angle is between 0° and 5°. The purpose of this arrangement is that, due to the inclined arrangement of the power mechanism, during the rotation of the impeller 3 and the movement of the water, a reaction force is provided to the aerator, which causes the aerator to passively rotate around the rotating base 21. It should be noted that, since the inclination angle of the power mechanism is small, its influence on the contact process between the spherical part 10 and the contact part 12 is negligible.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
