Description

Technical Field

[0001] The invention relates to the technical field of freshwater aquaculture hatching, in particular to a freshwater aquaculture hatching water filtering device. Background Art

[0002] Freshwater aquaculture is an important aquaculture method and is widely used in the global aquaculture industry. Freshwater aquaculture not only provides abundant aquatic products, but also brings significant benefits to people's diet, economy and ecological environment. In the process of freshwater aquaculture, fish hatching is a key link, which directly affects the survival rate and growth rate of fish.

[0003] For example, Chinese patent publication number CN118805716A relates to the technical field of aquaculture equipment and discloses an aquaculture hatching pond, including: a hatching pond, which is openly arranged and has a breeding area and a waste area therein, wherein the breeding area is located above the waste area, the waste area is connected to a drain pipe, the hatching pond is connected to a water inlet pipe, and has a hatching assembly therein. The present invention switches between the rotating plate and the wedge-shaped block. When the two form a horizontal plane, on the one hand, the excrement produced by the small fish can be directly dropped into the waste area through the channel, and on the other hand, the garbage on the platform can be pushed into the channel and dropped into the waste area; and when the two form a partition, on the one hand, the fresh feed can be intercepted, and on the other hand, the garbage in the waste area can be discharged through the drain pipe; this can avoid the waste of feed, ensure that the fry have sufficient eating time, and at the same time facilitate the cleaning of uneaten feed and fish feces.

[0004] Although the incubator can discharge garbage through the drain pipe and clean up uneaten feed and fish feces, when the fish eggs are hatching, the broken egg shells will produce a large number of broken shells.

However, the refluxed debris will be blocked by the outer wall of the hatching bucket, and the fry brought out by the water flow can swim back to the hatching bucket under the action of this reflux, so as to prevent the fry from being harmed.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 10The present invention provides a technical solution: a freshwater aquaculture hatching water filtering device, a freshwater aquaculture hatching water filtering device, comprising an incubation box 1, an incubation bucket 24 is fixedly installed on the inner wall of the incubation box 1 through a fixing plate 8, the incubation bucket 24 is divided into three sections, and the middle section is set to an inverted cone shape, a plurality of first filter holes 10 that can only supply water are opened on the outer wall of the fixing plate 8, a bottom plate 26 is installed at the bottom end of the incubation bucket 24, a spiral blade 11 is arranged at the center of the incubation bucket 24, a plurality of groups of incubation brushes 14 are installed on the outer wall of the spiral blade 11, and the incubation brush 14 is an attachment area, and an incubation component is also installed inside the incubation box 1;

[0036] It also includes an oxygen supply component, which can continuously supply oxygen to the inside of the hatching bucket 24 and can generate bubbles that float upward;

[0037] The device also includes an adjusting component that enables the spiral blade 11 to move up and down, and the spiral blade 11 can be attached to or separated from the inner wall of the middle section of the hatching bucket 24 when moving up and down.

[0038] Koi females usually choose to lay their eggs on brushes or other similar hatching carriers during the breeding process. This is because the fiber material on the brush provides an ideal attachment surface, allowing the eggs to firmly attach and facilitate subsequent hatching management. This process usually takes place in an artificial incubation environment in order to improve the hatchability of the eggs and protect the eggs from the outside environment.

[0039] See also Figure 3 When the device is used, the spiral blade 11 is fitted with the inner wall of the middle section of the hatching bucket 24. The parent fish (male fish and female fish) are first placed in the hatching bucket 24, and the aquaculture water in the hatching box 1 is placed in a suitable environment by adjusting the hatching components inside the hatching box 1 (temperature control equipment, oxygenation equipment, water quality monitoring equipment, lighting equipment, etc., all of which are existing technologies and will not be described in detail here). In this environment, the female fish will look for the hatching brush 14 to lay eggs, and the eggs will naturally adhere to the brush. At the same time, the male fish will be fertilized. In this process, the aquaculture water inside the hatching box 1 is supplied with oxygen through the oxygen supply component to ensure the smooth hatching of the eggs.

[0040] After the hatching of the fish eggs is completed, the egg shells are broken and are relatively light, so they are easy to float in the upper and middle layers of the water body. At this time, the spiral blade 11 is driven upward by the adjusting component, so that the spiral blade 11 is separated from the inner wall in the middle of the hatching bucket 24, and the oxygen supply component is adjusted to increase the air intake rate of the oxygen supply component. Some bubbles generated by the oxygen supply component can float up from the gap between the spiral blade 11 and the hatching bucket 24. When the bubbles encounter egg shell fragments during the rising process, the egg shell fragments will adhere to the surface of the bubbles or be wrapped by the bubbles. Since the buoyancy of the rising bubbles is large, it can overcome the gravity of the egg shell fragments and drive them to move upward. In the process of floating, the floating egg shell fragments are brought to the water surface by the buoyancy, so that the inside of the breeding water is kept clean, so that the fry and the remaining eggs have a good living space. When the preset After the time has passed, the spiral blade 11 is moved downward and reset by adjusting the component, and the spiral blade 11 is moved upward again. When the spiral blade 11 moves upward, since the area of ​​the spiral blade 11 is larger than the gap area generated by the spiral blade 11 and the hatching bucket 24 during this process, the breeding water in the hatching bucket 24 will surge upward, thereby driving the egg shells in the hatching bucket 24 to overflow from the hatching bucket 24 and fall onto the surface of the fixed plate 8. The overflowed water will return to the bottom of the hatching box 1 through the first filter hole 10, and the egg shells will be filtered by the first filter hole 10 and remain on the surface of the fixed plate 8, thereby completing the cleaning of the breeding water. Cleaning the egg shell fragments can effectively reduce organic pollutants, keep the water quality clean, provide a better environment for newly hatched fish eggs, reduce the mechanical damage of the egg shell fragments to the fish eggs during the hatching process, and improve the hatching rate.

[0041] Among them, it is worth mentioning that the hatching brushes 14 are all installed on the outer wall below the spiral blade 11. During the hatching stage, the oxygen provided by the oxygen supply component will gradually move upward along the outer wall below the spiral blade 11. In this process, the bubbles will also drive the egg shells in the hatching bucket 24 to move above the water surface while moving upward, assisting the next cleaning.

[0042] In addition, it is worth noting that the staff needs to clean the surface of the first filter hole 10 regularly to prevent the egg shell debris from accumulating and clogging the first filter hole 10, and Figure 3 As shown, the top of the fixed plate 8 is set as an inclined surface. When the spiral blade 11 moves upward to drive the water in the hatching bucket 24 and the egg shell fragments floating on the water surface to overflow to the surface of the fixed plate 8, the water flow is first dispersed to the surroundings. Under the action of the inclined surface on the top of the fixed plate 8, there will be a reflux effect toward the center. However, the refluxed debris will be blocked by the outer wall of the hatching bucket 24, and the fry brought out by the water flow can swim back to the hatching bucket 24 under the action of this reflux to prevent the fry from being harmed.

[0043] Furthermore, the oxygen supply assembly includes an eccentric groove 22 provided at the bottom of the incubation box 1, a rotatable piston body 16 is installed at the bottom of the eccentric groove 22, and the rotation axis of the piston body 16 coincides with the axis of the incubation bucket 24, a piston plate 19 is slidably installed on the inner wall of the piston body 16, piston rods 20 are fixedly installed on the outer walls of both sides of the piston plate 19, the two piston rods 20 both penetrate the outer wall of the piston body 16, and the two piston rods 20 can contact or separate from the inner wall of the eccentric groove 22, a connecting pipe 25 connected to an external oxygen generator is provided at the bottom of the piston body 16, the interior of the piston body 16 is connected to the interior of the incubation bucket 24 through the air inlet channel 18, and a one-way valve is installed in the connecting pipe 25 and the air inlet channel 18.

[0044] See also Figure 4 as well as Figure 7 The piston body 16 is driven to rotate by an external driving device. When the piston body 16 rotates, since the eccentric groove 22 is eccentrically arranged, when the piston body 16 drives the piston rod 20 to rotate, the two piston rods 20 will contact the inner wall of the eccentric groove 22 in turn, so that the piston plate 19 moves back and forth, and then the oxygen in the external oxygen generator is drawn into the piston body 16 through the connecting pipe 25, and then enters the hatching bucket 24 through the air inlet channel 18, thereby completing the oxygen supply to the breeding water.

[0045] Among them, the connecting pipe 25 and the incubation box 1 pass through the bottom of the incubation box 1 and are rotatably connected to the penetration point, one end of the connecting pipe 25 is fixedly connected to the bottom of the piston body 16, and the outer wall of the other end of the connecting pipe 25 is fixedly connected to the first gear, and a motor is fixedly installed at the bottom of the incubation box 1, and a second gear meshing with the first gear is fixedly installed on the outer wall of the output shaft of the motor to rotate the piston body 16. When the egg shells inside the incubation bucket 24 need to be cleaned, the rotation speed of the piston body 16 is increased by controlling the rotation rate of the motor output shaft, thereby increasing the number of bubbles entering the incubation bucket 24. More bubbles can increase the probability of contact with egg shell debris during the floating process, thereby increasing the cleaning effect.

[0046] Furthermore, the adjustment assembly includes a central rod 5 fixedly mounted on the top of the incubator 1, the bottom of the central rod 5 is rotatably connected to the piston body 16, a sliding sleeve 7 is slidably mounted on the outer wall of the central rod 5, and the spiral blade 11 is fixedly connected to the sliding sleeve 7;

[0047] The adjustment assembly also includes a control assembly capable of vertically moving the sliding sleeve 7 .

[0048] See also Figure 4The spiral blade 11 is fixed to the outer wall of the sliding sleeve 7, and the sliding sleeve 7 is slidably connected to the central rod 5. When the egg shells inside the hatching bucket 24 need to be cleaned, the sliding sleeve 7 can be moved upward by the control component, thereby driving the spiral blade 11 to move upward, and then the spiral blade 11 is separated from the inner wall of the hatching bucket 24. The bubbles filled into the hatching bucket 24 by the piston body 16 can drive the egg shell debris to move upward more quickly.

[0049] Furthermore, the control assembly includes a mounting plate 17 fixedly mounted on the outer wall of the center rod 5, an air bag 15 is fixedly mounted on the top of the mounting plate 17, an air inlet channel 18 is opened on the inner wall of the center rod 5 and the top of the piston body 16, the air bag 15 is connected with the inside of the piston body 16 through the air inlet channel 18, an air hole 23 that can be connected with the inside of the hatching bucket 24 is arranged on the top of the air bag 15, and a one-way valve is installed inside the air hole 23;

[0050] The control assembly also includes a spring 6 connecting the top of the incubation box 1 with the top of the sliding sleeve 7.

[0051] See also Figure 3 , the oxygen drawn from the oxygen generator by the piston body 16 will first enter the air bag 15 through the air inlet channel 18, and then enter the inside of the air hole 23 through the air hole 23. In the initial incubation stage, the rotation speed of the piston body 16 is relatively moderate, and the speed of the oxygen filled into the air bag 15 and the speed of the oxygen entering the hatching bucket 24 from the air hole 23 will maintain a balance. When the egg shell debris in the hatching bucket 24 needs to be cleaned, the power of the motor is adjusted to increase the rotation speed of the piston body 16, so that the oxygen enters the air bag 15 more quickly. Since the inner diameter of the air inlet channel 18 is larger than the air hole 23, the rotation speed of the piston body 16 is increased. The inner diameter of the hole 23 is such that when the oxygen velocity entering the air bag 15 increases, the oxygen velocity entering the hatching bucket 24 through the air hole 23 will be lower than the oxygen velocity entering the air bag 15, thereby causing the air bag 15 to expand, thereby driving the sliding sleeve 7 and the spiral blade 11 to move upward, thereby causing the spiral blade 11 to separate from the inner wall of the hatching bucket 24, so that the oxygen entering the hatching bucket 24 can more quickly drive the egg shell debris inside the hatching bucket 24 to float upward, and, through the rapidly rising bubbles, the dissolved oxygen content in the water can be more effectively increased, thereby promoting the healthy growth of fish eggs and seedlings.

[0052] Furthermore, a plurality of circular grooves are provided on the outer wall of the spiral blade 11, and an incubation plate 12 is installed on the inner wall of each circular groove. A incubation brush 14 is installed on the lower end of the incubation plate 12, and a plurality of fixing rods 9 are fixedly installed on the top of the mounting plate 17. The fixing rods 9 pass through the center of the incubation plate 12, and a plurality of cleaning plates 13 corresponding to the incubation plate 12 are installed on the outer wall of each fixing rod 9, and a slot hole for the incubation brush 14 to penetrate is provided on the outer wall of each cleaning plate 13.

[0053] Furthermore, the moving distance of the spiral blade 11 will not exceed the length of the hatching brush 14 .

[0054] During the hatching process of freshwater aquaculture, fish eggs are usually attached to brushes or other hatching carriers. However, not all fish eggs can be successfully hatched. Some fish eggs will fail to hatch and continue to adhere to the fibers of the brush. In addition, when the fish eggs are hatched and broken, the egg shells will also remain in the gaps of the brush. If these failed eggs and remaining egg shells are not cleaned up in time, they may have an adverse effect on water quality and further affect the healthy growth of seedlings. Therefore, it is very necessary to clean the brush regularly. This embodiment focuses on solving the problem of fish eggs and egg shell residues. The specific implementation method is as follows:

[0055] See also Figure 3 A circular hole is formed on the surface of the spiral blade 11, and a hatching plate 12 is fixedly installed in the circular hole. In the initial hatching stage, the cleaning plate 13 is fitted with the hatching plate 12, so that the hatching brush 14 passes through the cleaning plate 13 and is exposed inside the hatching bucket 24, so that the parent fish can reproduce in the hatching brush 14. After the preset time (i.e., the hatching time of the fish eggs), the fish eggs that have not yet been hatched may fail to hatch. At this time, by adjusting the rotation speed of the connecting pipe 25, oxygen can enter the air bag 15 more quickly, so that it expands and drives the slide The movable sleeve 7 moves upward, and the sliding sleeve 7 moves upward, which will drive the spiral blade 11 and the hatching plate 12 to move upward, and then drive the hatching brush 14 to move upward. Since the cleaning plate 13 is fixed to the outer wall of the fixed rod 9, when the hatching brush 14 moves upward, the cleaning plate 13 will scrape off the fish eggs and egg shell fragments that have failed to hatch between the hatching brushes 14, causing them to fall into the water in the hatching bucket 24, and then the bubbles that enter the hatching bucket 24 through the piston body 16 drive it to move upward, so as to complete the subsequent cleaning.

[0056] Among them, it is worth noting that the moving distance of the spiral blade 11 can also be controlled not to exceed the length of the hatching brush 14. Referring to the first filter hole 10 in the figure, in the process of the bubble driving the egg shell debris to move upward, it may contact the hatching brush 14, thereby driving the egg shell debris into the gap between the hatching brush 14. When the moving distance of the spiral blade 11 does not exceed the length of the hatching brush 14, the hatching brush 14 will be protected in the space between the hatching plate 12 and the cleaning plate 13 to prevent the hatching brush 14 from causing secondary pollution.

[0057] Furthermore, the bottom plate 26 is slidably connected to the hatching bucket 24 , and the bottom of the bottom plate 26 is fixedly connected to the top of the air bag 15 .

[0058] It can be seen from the above embodiment that by introducing air bubbles into the hatching bucket 24, the egg shell fragments therein can be driven to the water surface, and then the piston body 16 is expanded to make the egg shell fragments on the water surface fall onto the first filter hole 10 to complete the filtration. However, the fish eggs that have not been completely hatched and the garbage generated by the fry therein are relatively heavy and cannot be cleaned by the floating method of air bubbles. Therefore, this embodiment focuses on cleaning the garbage that cannot be driven by the air bubbles, and the specific implementation method is as follows:

[0059] See also Figure 3 , the bottom plate 26 is slidably connected to the hatching bucket 24, and a plurality of tiny through holes are provided at the bottom of the bottom plate 26, through which only garbage and water can pass. In the initial stage of hatching, the bottom plate 26 will block the bottom of the hatching bucket 24, and most of the garbage will be discharged into the eccentric groove 22 through the tiny through holes, and then discharged from the outside of the hatching box 1; when the hatching reaches the later stage, the garbage and unhatched fish eggs in the hatching bucket 24 will be accumulated, and at this time, the rotation speed of the piston body 16 will be reduced, so that the air bag 15 will shrink, thereby driving the bottom plate 26 to move downward, so that the bottom plate 26 is separated from the hatching bucket 24, and the external water source is connected to the inside of the hatching bucket 24, so that the water flow flows into the hatching bucket 24, and the bottom of the hatching box 1 is connected to the wastewater pipe. In this process, the water flow flowing in from the top of the hatching bucket 24 will gradually flow downward along the spiral direction of the spiral blade 11, so that the garbage debris inside it will be left out from the gap between the bottom plate 26 and the hatching bucket 24, and then discharged through the wastewater pipe, so as to complete the cleaning of the garbage inside it.

[0060] Furthermore, a water inlet 3 is provided at the top of the incubation box 1 , a water outlet 4 is provided at the bottom of the incubation box 1 , a remote control component 2 is installed on the outer wall of the incubation box 1 , and the remote control component 2 is electrically connected to the incubation component inside the incubation box 1 .

[0061] See also Figure 1 as well as Figure 2 When it is necessary to clean the garbage in the hatching bucket 24, clean water can flow in through the water inlet 3, and turbid water can be discharged through the water outlet 4. In this process, the hatching component can be controlled by the remote control component 2 so that seedlings at different stages can be in the most suitable growth environment.

[0062] Furthermore, an elastic scraper 21 is installed on the outer wall of the piston body 16 .

[0063] See also Figure 8 as well as Fig. 9 During the rotation of the piston body 16 , the elastic scraper 21 can prevent the bottom of the eccentric groove 22 from being scraped and cleaned, thereby preventing the garbage produced by the fry from adhering to the bottom of the eccentric groove 22 .

[0064] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
