Description

Technical Field

[0001] This utility model relates to the field of incubation bottle technology, specifically an incubation device for naked bream eggs. Background Technology

[0002] Publication (Announcement) No.: CN215380800U, Patent Title: A fish egg hatching device, comprising a hatching tank, the hatching tank including a first tank body, a water inlet pipe and a discharge pipe, the bottom of the first tank body is provided with a conical protrusion, the water inlet pipe is fixed inside the first tank body and the outlet of the water inlet pipe is located directly above the protrusion, the upper side wall of the first tank body is connected to the discharge pipe. This utility model provides a fish egg hatching device that requires only a relatively small initial water flow velocity to effectively tumble the fish eggs inside the first tank, thereby improving the hatching rate.

[0003] Our company mainly focuses on hatching naked wrasse eggs. When hatching naked wrasse eggs in large quantities, we prevent dead eggs from growing water mold and infecting normal fish eggs. At the same time, the protein in dead eggs absorbs water faster, resulting in a lower density of dead eggs compared to live eggs.

[0004] The applicant applied for the use of the above-disclosed technical solution for the mass hatching of naked-bottomed fish eggs; however, the following problems were found:

[0005] 1. The hatching bottle uses water flow to keep the fish eggs in a floating and rolling state. Although this can prevent dead eggs from coming into contact with normal eggs and infecting them with water mold, dead eggs and normal eggs are still in the hatching bottle, so there will still be contact between dead eggs and normal eggs.

[0006] 2. In the disclosed technical solution, the first barrel 1 is an inverted cone shape, and the bottom and sidewall of the first barrel 1 are smoothly transitioned. The flow direction of the water gradually changes, and the change in flow direction after the water flow impacts the protrusion 4 is small. The water flow is orderly, reducing the kinetic energy loss of the water flow. However, the small change in flow direction will cause the fish eggs to roll at a small angle with the water flow, resulting in the fish eggs accumulating at the bottom of the first barrel, increasing the probability of dead eggs coming into contact with normal eggs. Utility Model Content

[0007] The purpose of this invention is to provide a hatching device for naked wrasse eggs to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A hatching device for naked wrasse eggs includes a hatching bottle with an inner wall that is hollow and a hemispherical bottom. A water inlet pipe is centrally mounted on the hatching bottle via a bracket. The water inlet pipe extends vertically into the cavity and its bottom is positioned above the inner wall of the hemispherical bottom. A barrier is provided above the outer wall of the hatching bottle, and an observation platform is provided inside the barrier. A water outlet is provided on one side of the barrier.

[0010] In a preferred embodiment of this utility model, the bracket includes a sleeve, and a rubber anti-slip layer is fixedly installed on the inner wall of the sleeve, with the inner wall of the rubber anti-slip layer contacting the outer wall of the water inlet pipe.

[0011] In a preferred embodiment of this utility model, a support arm is fixedly provided on the outer circumference of the sleeve, and a clamping head is fixedly provided at the end of the support arm away from the sleeve. A clamping groove is provided at the bottom of the clamping head, and an anti-slip rubber layer II is fixedly installed on the inner wall of the clamping groove. The anti-slip rubber layer II is connected to the top of the incubation bottle.

[0012] In a preferred embodiment of this utility model, a connector is installed on the top of the inner wall of the water inlet pipe.

[0013] In a preferred embodiment of this utility model, the incubation bottle is made of acrylic material, the incubation bottle is 60cm high and 20cm in diameter, and the water inlet pipe is 5cm in diameter.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0015] The incubation bottle is a vertical cylinder with a hemispherical bottom. When fresh water enters the cavity through the inlet pipe, the water contacting the hemispherical bottom causes the naked bream eggs to flip upwards. After reaching the top of the cavity, because the density of the naked bream eggs is greater than that of water, and the downward force of gravity is greater than the upward thrust of the water flow, they begin to fall back to the bottom of the cavity. Then, influenced by the thrust of the water in the inlet pipe, the naked bream eggs tumble inside the cavity. Because the naked bream eggs tumble continuously inside the cavity, the probability of dead eggs coming into contact with live eggs is reduced.

[0016] As water continuously enters the cavity through the inlet pipe, it overflows from the top of the incubation bottle, flows into the observation platform of the enclosure, and then exits from the outlet. Due to the high density of naked bream eggs, as long as the water inlet speed is controlled, the naked bream eggs will flow upward with the water flow to the top of the incubation bottle and then move downward due to gravity, forming a back-and-forth tumbling motion. In addition, the density and flow speed of dead eggs and live eggs are different, which can greatly reduce the chance of dead eggs coming into contact with normal eggs.

[0017] Its observation platform features a dark design, making it easy for users to observe the number of live and dead eggs carried out by the water flow. Attached Figure Description

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figure 1-5 A hatching device for naked bream eggs includes a hatching bottle 100, the inner wall of the hatching bottle 100 being a cavity 120, the bottom of the cavity 120 being a hemispherical bottom 110, a water inlet pipe 300 being centrally mounted on the hatching bottle 100 via a bracket 200, the water inlet pipe 300 extending vertically into the cavity 120, the bottom of the water inlet pipe 300 being positioned above the inner wall of the hemispherical bottom 110, a enclosure 130 being provided above the outer wall of the hatching bottle 100, an observation platform 140 being provided inside the enclosure 130, and a water outlet 150 being provided on one side of the enclosure 130;

[0027] Specifically, the incubation bottle 100 is a vertical cylinder with a hemispherical bottom 110. When live water enters the cavity 120 from the inlet pipe 300, the water contacts the hemispherical bottom 110 and causes the naked bream eggs to flip upwards. After the naked bream eggs reach the top of the cavity 120, because the density of the naked bream eggs is greater than that of water, and the downward force of gravity is greater than the upward thrust of the water flow, they begin to fall back to the bottom of the cavity 120. Then, under the influence of the thrust of the water in the inlet pipe 300, the naked bream eggs are tumbling in the cavity 120. Because the naked bream eggs are constantly tumbling in the cavity 120, the probability of dead eggs coming into contact with live eggs is reduced.

[0028] As water continuously enters the cavity 120 from the inlet pipe 300, it overflows from the top of the incubation bottle 100, flows into the observation platform 140 of the enclosure 130, and then exits from the outlet 150. Since the density of dead eggs is lower than that of live eggs, as long as the water inlet speed of the inlet pipe 300 is controlled, when the naked wrasse eggs roll upward, the dead eggs will also move upward. The normal eggs move downward due to gravity. The dead eggs continue to move upward, and their downward gravity is less than the thrust of the water flow. Then they overflow from the top of the incubation bottle 100, flow to the observation platform 140, and then exit from the outlet 150. This can greatly reduce the chance of dead eggs coming into contact with normal eggs.

[0029] Its observation platform 140 features a dark design, making it easy for users to observe the number of live and dead eggs carried out by the water flow, thereby controlling the water intake speed of the inlet pipe 300.

[0030] The bracket 200 includes a sleeve 210, on the inner wall of which a rubber anti-slip layer 220 is fixedly installed. The inner wall of the rubber anti-slip layer 220 contacts the outer wall of the water inlet pipe 300. Specifically, the sleeve 210 has a positioning function for the water inlet pipe 300, and the rubber anti-slip layer 220 has an anti-slip function for the water inlet pipe 300. The sleeve 210 and the water inlet pipe 300 are assembled by insertion, which can adjust the distance at which the water inlet pipe 300 extends into the cavity 120.

[0031] A support arm 230 is fixedly provided on the outer circumference of the sleeve 210. A clamp head 240 is fixedly provided at the end of the support arm 230 away from the sleeve 210. A groove 250 is provided at the bottom of the clamp head 240. An anti-slip rubber layer 260 is fixedly installed on the inner wall of the groove 250. The anti-slip rubber layer 260 is connected to the top of the incubation bottle 100. Specifically, by clamping the clamp head 240 on the top of the incubation bottle 100, the water inlet pipe 300 can be fixed in the middle part of the incubation bottle 100, which is convenient and quick to assemble.

[0032] A connector 400 is installed on the top of the inner wall of the water inlet pipe 300. The connector 400 is used to connect the water pipe to an external water source.

[0033] The incubation bottle 100 is made of acrylic material, and the incubation bottle 100 is 60cm high and 20cm in diameter. The water inlet pipe 300 has a diameter of 5cm.

[0034] The working principle of this utility model is as follows: the connector 400 is connected to the water pipe of the external water source. When the live water enters the cavity 120 from the inlet pipe 300, the water contacts the hemispherical bottom 110 and causes the naked bream eggs to turn upward. After the naked bream eggs reach the top of the cavity 120, because the density of the naked bream eggs is greater than that of water, and the downward gravity is greater than the upward thrust of the water flow, they begin to fall back to the bottom of the cavity 120. Then, under the influence of the thrust of the water in the inlet pipe 300, the naked bream eggs are rolled in the cavity 120.

[0035] Because the density of dead eggs is lower than that of live eggs, when the naked wrasse eggs roll upwards, the dead eggs will also move upwards. The normal eggs move downwards due to gravity, while the dead eggs continue to move upwards. Their downward gravity is less than the thrust of the water flow, so they overflow from the top of the incubation bottle 100, flow to the observation platform 140, and then are discharged from the outlet 150.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
