Description

Technical Field

[0001] The utility model relates to the field of aquaculture equipment, in particular to a rainbow trout hatching and disinfecting device. Background Art

[0002] Rainbow trout is a precious cold-water fish species. When rainbow trout eggs are hatching, they need flowing water to provide oxygen. The hatching temperature is generally around 8-10 degrees.

[0003] Currently, rainbow trout hatching mainly faces three major problems, namely, the problem of disinfection during the hatching process, the problem of the need for breeding water during hatching, and the problem of small hatching capacity of the hatching equipment.

[0004] (1) Dead eggs may appear during the incubation of rainbow trout. There are two conventional ways to deal with dead eggs. One is to pick out the dead eggs, and the other is to eliminate them all. Both methods are either laborious or wasteful. It is best to use disinfection, but there is currently no effective method for disinfecting rainbow trout eggs.

[0005] (2) At present, the domestic rainbow trout hatching basically relies on spring water to provide flowing water. This method has the following problems: (1) Waste of water resources; (2) Since it relies entirely on natural spring water, the water temperature of the spring water is too low in winter and cannot be regulated. If the temperature is too low, such as 6 degrees or lower, it will cause the incubation period to be too long, affecting the hatching of rainbow trout; (3) Since it must rely on spring water, the equipment is limited in use, has poor applicability, and the hatching capacity is not high.

[0006] (3) At present, when hatching rainbow trout, a multi-layer flat tray structure is generally used. In the multi-layer flat tray form, flowing water flows in from one end, flows out from the other end, and then falls into the lower tray. This hatching structure has a small number of fish eggs hatched in each tray, low hatching efficiency, large floor space, and high equipment cost. It is also not suitable for fish egg disinfection.

[0007] As can be seen from the above, the above-mentioned existing rainbow trout hatching and disinfection equipment still has inconveniences and defects in structure and use, and is in urgent need of further improvement. Utility Model Content

[0026] 6. In the overflow hatching barrel, the flowing water can pass through the funnel and the water injection column in sequence, flow out from the bottom of the water injection column, and then pass through the second through hole on the grate to provide flowing water to the rainbow trout eggs laid on the grate, and finally the flowing water flows out from the opening at the top of the barrel. The whole process ensures the flowing water required for the hatching of rainbow trout eggs, and the flowing water will not directly impact the rainbow trout eggs, greatly improving the hatching efficiency of the eggs. The eggs can be laid on the grate in multiple layers, which can be suitable for the hatching of a large number of rainbow trout eggs.

DETAILED DESCRIPTION

[0035] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] The rainbow trout hatching and disinfection equipment provided in this embodiment includes a rainbow trout hatching equipment and a rainbow trout disinfection equipment; the rainbow trout hatching equipment includes a water supply system and a hatching device, the water in the water supply system flows into the hatching device through a water valve and flows out of the hatching device; the rainbow trout disinfection equipment includes a disinfection barrel, a drainage pipe is arranged on the disinfection barrel, the disinfectant in the drainage pipe flows into the hatching device during disinfection, and flows out of the hatching device at the same time as the water.

[0037] The following is combined with Figure 1-5 The rainbow trout hatching and disinfecting equipment of the present embodiment is described in detail.

[0038] like Figure 1 , 2 As shown, the water supply system in the rainbow trout hatching device includes a water inlet device 1, a water tank 3 and a water outlet device 4; the water tank 3 is placed on the support frame 2; the water inlet device 1 includes a water pump (not shown in the figure) and a water inlet pipe 11, the water pump connects the water inlet pipe 11 and the water storage tank 5, the water outlet of the water inlet pipe 11 is located at the upper part of the water tank 3, the water in the water storage tank 5 is introduced into the water inlet pipe 11 through the water pump, and falls into the water tank 3 from the upper part of the water tank 3 (the water flow direction is detailed in FIG. Figure 1The arrow in the figure points to the direction); the water outlet device 4 includes a water outlet pipe 41 connected to the lower part of the water tank and a plurality of branch pipes 42 connected to the water outlet pipe 41, and a water valve 43 is provided on the branch pipe 42. The water valve 43 is used to adjust the water flow. When hatching rainbow trout eggs, the water flow cannot be too large. If it is too large, it will impact the fish eggs, and the fish eggs will easily die if they move. If the water flow is too small, it will easily cause hypoxia, so the water flow size is adjusted by the water valve 43; preferably, the water outlet pipe 41 includes a vertical pipe 411 and a transverse pipe 412, the upper end of the vertical pipe 411 is connected to the lower part of the water tank 3 through an elbow, and the transverse pipe 412 is connected to the lower end of the vertical pipe 411 through an elbow; the branch pipes 42 are respectively horizontally and perpendicular to the transverse pipe 412 and are evenly distributed on the transverse pipe 412.

[0039] The rainbow trout disinfection equipment includes a disinfection barrel 8, which is placed on a support frame 2. A drainage tube 9 is provided on the disinfection barrel 8, and the disinfectant in the drainage tube 9 flows into the hatching device during disinfection. Preferably, multiple disinfection barrels 8 can be provided. Since not every hatching device needs to be disinfected at the same time, the number of hatching devices can be more than the number of disinfection barrels 8, such as each disinfection barrel corresponds to 1-2 hatching devices. As a preferred embodiment, the drainage tube 9 is a siphon drainage tube, preferably a rubber tube. When in use, the disinfectant can be drawn out by sucking it through a suction head at the water outlet end of the drainage tube 9. The other end of the drainage tube 9 is placed in the disinfection barrel 8, and a countersunk head is used here.

[0040] The rainbow trout hatching equipment also includes a plurality of hatching devices. In this embodiment, an overflow hatching bucket 6 is preferably used. The overflow hatching bucket 6 is respectively located below the drainage pipe 9 of the branch pipe 42 and the disinfection bucket 8; the plurality of overflow hatching buckets 6 are placed in a water collecting tank 7, and the water collecting tank 7 is provided with a water outlet; when no disinfection is required, the water in the branch pipe 42 flows into the overflow hatching bucket 6 and flows into the water collecting tank 7 and the water storage tank 5 in turn through the overflow (the water flow direction is detailed in FIG. Figure 1 When disinfection is needed, the drainage pipe 9 is opened, the water outlet from the water collecting tank 7 to the water storage tank 5 is closed, and the water outlet to the wastewater tank (not shown in the figure) is opened. The flow rate can be adjusted by adjusting the opening size of the water valve 43, and the concentration of the disinfectant and the disinfection time can be adjusted by adjusting the flow rate.

[0041] Before using the rainbow trout hatching and disinfecting device of the utility model, the water temperature in the water storage tank 5 is adjusted first, and the water temperature is generally adjusted to about 8-10 degrees. The water storage tank can be set anywhere. In addition, it should be noted that the conditions in different regions and seasons are different, and can be adjusted according to actual conditions.

[0042] When the device is used, the water pump introduces the water in the water tank 5 into the water inlet pipe 11, and drops into the water tank 3 from the top of the water tank 3. Here, the height difference of the drop is used to make the water in the water tank 3 continuously produce dissolved oxygen, and dissolved oxygen is an important influencing factor for the hatching of rainbow trout eggs. The water containing dissolved oxygen then flows into the overflow hatching bucket 6 through the branch pipe 42 on the outlet pipe 41, and then overflows from the overflow hatching bucket 6 after providing flowing water to the fish eggs. At this point, the hatching of rainbow trout eggs is realized. If the overflowing water flows directly into the drain ditch as usual, there will be a waste of water resources, and more water will be discharged, and more water needs to be adjusted in the water tank 5. Therefore, as a preferred embodiment, the overflowing water in this embodiment enters the water collecting tank 7, and the overflowing water can be temporarily stored in the water collecting tank 7, and then directly flows into the water tank 5 through the water outlet of the water collecting tank 7. Here, the recycling of water is realized, and while saving water, a suitable water source is continuously provided to the water tank 5.

[0043] During the process of hatching fish eggs, if dead eggs are found, it is necessary to turn on the disinfection equipment. At this time, the drainage pipe 9 is opened, the water outlet from the water collection tank 7 to the water storage tank 5 is closed, and the water outlet from the water collection tank 7 to the wastewater tank is opened. The flow rate can be adjusted by adjusting the opening size of the water valve 43. The concentration of the disinfectant and the disinfection time can be adjusted by adjusting the flow rate, thereby preventing diseases.

[0044] The rainbow trout hatching and disinfection equipment of this embodiment can handle dead eggs in time, and the disinfection is convenient and has a good disinfection effect. In addition, the equipment can save water, and does not need to rely on mountain spring water, only a water storage tank is used, and the water in the water storage tank can adjust the water temperature according to actual needs. At the same time, since it does not need to rely on mountain spring water, its use site does not need to be restricted, which greatly expands the use site of the equipment and also increases the hatching capacity.

[0045] In the above embodiment, the number of overflow hatching buckets 6 can be selected according to the actual hatching amount, such as 8-10. If there are few eggs, the number of overflow hatching buckets 6 can be reduced according to demand. The support frame 2 can be any form of simple structure support frame, such as iron frame, stainless steel frame, etc.

[0046] Since the rainbow trout eggs should not be subjected to excessive impact and disturbance during hatching, as a preferred embodiment, the inventor has found through a large amount of practice that gauze (not shown in the figure) can be wrapped at the outlet of the branch pipe 42. The gauze can play a filtering role and control the water flow of the outlet, so that the water flowing into the overflow hatching bucket 6 is not easy to generate bubbles, which is conducive to the hatching of the eggs.

[0047] In order to provide dissolved oxygen for rainbow trout eggs, in this embodiment, at the water tank 3, the water outlet through the water inlet pipe 11 can fall into (hit the water tank 3) to generate dissolved oxygen. At this time, the water inlet volume is generally large, and in order to ensure that the rainbow trout eggs are not easily impacted, the water outlet volume (flow rate) of the water outlet pipe 41 and the branch pipe 42 needs to be controlled. In view of this contradiction, in this embodiment, a return pipe 12 is preferably connected to the upper part of one side of the water tank 3, and the bottom of the return pipe 12 is connected to the water storage tank 5. An overflow pipe 13 is also included, and the upper part of the water tank 3 is respectively connected to the upper end of the return pipe 12 and the lower end of the overflow pipe 13 through a tee. In this way, when in use, if there is too much water in the water tank 3, it will flow back into the water storage tank 5 from the return pipe 12, or further overflow from the overflow pipe 13.

[0048] The existing incubation device has the problems of small incubation capacity, low incubation efficiency, large floor space and high equipment cost. In view of this problem, this embodiment further optimizes and improves it.

[0049] Cooperate Figure 3-5 As shown, the hatching device of this embodiment adopts an overflow hatching barrel 6, including: a barrel body 61, a grate 62, a water injection pipe column 63 and a funnel 64; the barrel body 61 is open at the top; the grate 62 is horizontally placed in the barrel body 61, dividing the barrel body 61 into two upper and lower spaces; a first through hole 621 is arranged in the middle of the grate 62, and the water injection pipe column 63 vertically passes through the first through hole 621 of the grate 62, and a plurality of second through holes 622 are evenly arranged on the grate 62, and the grate 62 is used to lay rainbow trout eggs, and the aperture of the second through holes 622 is smaller than the diameter of the rainbow trout eggs; the funnel 64 is inserted into the top opening of the water injection pipe column 63.

[0050] The various components of the overflow hatching bucket 6 are detachable for easy cleaning. When in use, the various components are assembled according to the above-mentioned matching relationship, and the funnel 64 can be inserted into the water injection column 63 after the other parts of the hatching bucket are assembled.

[0051] When incubating rainbow trout eggs, the rainbow trout eggs are laid on the grate 62, and multiple layers can be laid. For a grate with a diameter of about 30 cm, about 30,000 eggs can be laid after multiple layers are laid. Then the water valve 43 on the branch pipe 42 is opened, and the flowing water slowly flows into the funnel 64. Next, the flowing water can pass through the funnel 64 and the water injection column 63 in sequence, flow out from the bottom of the water injection column 63, and then pass through the second through hole 622 on the grate 62, and finally flow out from the top opening of the barrel body 61.

[0052] Through this flowing water circulation method, the flowing water required for the hatching of rainbow trout eggs is guaranteed, and the flowing water will not directly impact the rainbow trout eggs, which greatly improves the hatching efficiency of the eggs. The eggs can be laid in multiple layers on the grate, which can be suitable for the hatching of a large number of rainbow trout eggs.

[0053] As a preferred embodiment, Figure 4 , 5 As shown, the water injection column 63 is a cylindrical column as a whole; its bottom is set as a sawtooth end 631, forming a plurality of triangular water outlets, and the vertex angle of the triangle is preferably less than 45 degrees. In this case, the bottom end of the water injection column 63 contacts the bottom of the barrel body 61, and a plurality of triangular water outlets are formed therebetween. By setting the sawtooth end 631, a part of the water flow can be blocked, which has a certain buffering effect on the water flow, so that the water flow can slowly diffuse outward and then flow upward through the second through hole 622 of the grate 62.

[0054] Cooperate Figure 4 As shown, an upward limiting protrusion 611 is provided in the middle of the bottom of the barrel body 61, and the serrated end 631 of the water injection column 63 is sleeved on the limiting protrusion 611, and a plurality of triangular water flow outlets are formed between the limiting protrusion 611 and the serrated end 631. By providing the upward limiting protrusion 611 in the middle of the bottom of the barrel body 61, the water injection column 63 can be limited and fixed, and the installation stability of the water injection column 63 is further improved. In addition, the barrel body 61 is preferably an inverted truncated cone barrel body, and a boss is provided in the middle and lower part of the inner side wall of the barrel body 61, and the grate 62 is placed on the boss in the barrel body 61.

[0055] In order to ensure that the grate 62 is stable when the water flow impacts in the reverse direction, the grate 62 in this embodiment is preferably made of fiberglass. Similarly, the barrel body 61 is also made of fiberglass, which is more suitable for the scene of water circulation than ordinary plastic material, thereby improving the stability of the entire barrel body 61.

[0056] In the present embodiment, the flowing water flows out from the upper opening of the barrel body 61 , and an outward turning edge is provided at the upper opening of the barrel body 61 , and the outward turning edge is used to guide the water to overflow.

[0057] Through the overflow hatching barrel, the flowing water can pass through the funnel and the water injection column in sequence, flow out from the bottom of the water injection column, and then pass through the second through hole on the grate to provide flowing water to the rainbow trout eggs laid on the grate, and finally the flowing water flows out from the opening at the top of the barrel body. The whole process ensures the flowing water required for the hatching of rainbow trout eggs, and the flowing water will not directly impact the rainbow trout eggs, greatly improving the hatching efficiency of the fish eggs. The fish eggs can be laid on the grate in multiple layers, which can be suitable for the hatching of a large number of rainbow trout eggs and is suitable for promotion and application.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
