Technical Field

[0001] The utility model relates to an incubator, in particular to a floating-egg incubator. Background Art

[0002] There are many existing floating-egg hatching styles, including hatching in a cement pool with water flushing and hatching in an incubation barrel. Hatching in a cement circular pool has high costs, large floor areas, is inflexible, inconvenient to move and carry, and cannot be used for hatching at a designated location according to actual needs. The incubation barrel is an incubator used more in current fish proliferation and release stations. The incubation barrel mainly takes the way of water inlet at the bottom and water outlet at the upper part, with the water body constantly tumbling upward for hatching, which cannot meet the flow rate requirements of floating eggs. The egg membranes after hatching at the upper water outlet are prone to block the overflow net, affecting the hatching of fertilized eggs. Content of the Utility Model

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The utility model is a drifting egg incubator with a simple structure, easy operation, detachability, low cost and low water consumption. It solves the problems of spawning and reproduction of fish laying drifting eggs and hatching of fertilized eggs, and effectively reduces the problem that the overflow net is easily blocked by the egg membrane after hatching during the hatching of fertilized eggs, resulting in unsatisfactory hatching effect, and the like. It can be used for experimental institutions for small-batch production, fish proliferation and release stations for large-scale production, and large-scale fish farms.

[0023] The utility model provides a floating egg incubator, which adopts a cylindrical structure, a central overflow, and simulates the hatching conditions of a natural river by simulating the way of natural river by water inlet. Figures 1 to 3 , comprising a water inlet system 1, a hatching tank 2 and an overflow unit 3;

[0024] The hatching cylinder 2 comprises a hatching cylinder body 2-1 and a hatching cylinder bottom 2-2; the hatching cylinder body 2-1 is in a barrel shape with a cross section that decreases from top to bottom.

[0025] The water inlet system 1 includes a main water inlet pipe 1-1, a branch water inlet pipe 1-2, a water inlet switch 1-3 and a water outlet pipe 1-4;

[0026] In the cavity of the hatching tank 2, with the central axis of the hatching tank 2 as the reference, multiple vertically arranged branch inlet pipes 1-2 are fixedly installed at equal intervals around the central axis; a total of 4 branch inlet pipes 1-2 are installed in the figure; the specific number of the branch inlet pipes 1-2 is flexibly set according to actual needs. The water inlet ends of each branch inlet pipe 1-2 are communicated with the water outlet end of the main inlet pipe 1-1; water inlet switches 1-3 are installed on both the branch inlet pipes 1-2 and the main inlet pipe 1-1; at different height positions of each branch inlet pipe 1-2, water outlet pipes 1-4 are provided, and water flows are sprayed into the cavity of the hatching tank 2 through each water outlet pipe 1-4; among them, for the water outlet pipes 1-4 at different height positions on the same branch inlet pipe 1-2, the water outlet angles are as follows: the upper and middle water outlet pipes 1-4 are horizontally arranged for spraying horizontal water flows; the lowermost water outlet pipe 1-4 is inclined downward for spraying inclined water flows downward. By setting the water inlet system 1, the water outlet pipes 1-4 with different heights and water outlet angles can discharge water, which can promote the flow of the water body in the incubator, create a flow rate, and provide a flowing water hatching environment for the drifting eggs. The lowermost water outlet pipe 1-4 discharges water toward the bottom, which can promote the flow of the water body and also create the water body to roll upward from the bottom, simulating the "bubble whirlpool" of a natural river, that is, the water body rolls up and down and vertically exchanges. This design can prevent the fertilized eggs from sinking to the bottom, thus ensuring the normal hatching of the fertilized eggs.

[0027] An overflow unit 3 is installed at the central position of the cavity of the hatching tank 2. The overflow unit 3 is designed to be detachable, which is easy to empty the water body in the incubator and convenient for maintenance and replacement, etc.

[0028] The overflow unit 3 includes an overflow mesh cover 3-1, an elastic tightening opening 3-2, a drainage pipe 3-3, and a stainless steel hollowed-out bracket 3-4;

[0029] The drainage pipe 3-3 is arranged at the central position of the cavity of the hatching tank 2. The bottom of the drainage pipe 3-3 is detachably connected to the center of the bottom of the hatching tank 2, for example, by threaded connection; the top of the drainage pipe 3-3 is detachably installed with a stainless steel hollowed-out bracket 3-4, for example, by threading the stainless steel hollowed-out bracket 3-4; the replaceable overflow mesh cover 3-1 is wrapped outside the stainless steel hollowed-out bracket 3-4; the mouth of the overflow mesh cover 3-1 is an elastic tightening opening, which is convenient for replacement. The top surface of the overflow mesh cover 3-1 is lower than the top of the hatching tank 2 to form an overflow effect.

[0030] The overflow unit 3 has the following innovative design: the overflow mesh cover 3-1 supported by the stainless steel bracket is in an inverted triangular shape and is inclined, inclined at a certain angle toward the water body side. Therefore, when draining water through the overflow unit 3 during the hatching process of the hatched eggs, due to the flushing effect of the water body flow, the problem that the hatched egg membranes adhere to the overflow mesh cover 3-1 and cause the overflow mesh to be blocked can be avoided.

[0031] A floating-egg incubator provided by the present utility model adopts a barrel-shaped structure and a central overflow method to simulate the hatching conditions of natural rivers. Its working process is as follows:

[0032] When the incubator is running, open the water inlet switches 1-3 of the main water inlet pipe 1-1 and the branch water inlet pipe 1-2. By controlling the water flow velocity, after the water body passes through the main water inlet pipe 1-1, it flows into each branch water inlet pipe 1-2 respectively, and then flows out from the water outlet pipes 1-4 at different height positions of each branch water inlet pipe 1-2, and thus flows into the hatching tank 2; the water flowing out from the water outlet pipes 1-4 can drive the water body in the incubator to flow, create a flow velocity, and provide a flowing water hatching environment for the floating eggs. The water outlet pipes 1-4 at the bottom face downward to discharge water, which can drive the water body to flow, and in addition, can create the water body to roll upward from the bottom, simulating the "bubble whirlpool water" of natural rivers, that is, the water flows up and down and vertically exchanges, preventing the fertilized eggs from sinking to the bottom, thereby ensuring the normal hatching of the fertilized eggs.

[0033] When the water body continuously flows into the hatching tank 2, the water surface in the hatching tank 2 continuously rises. When it reaches the height of the overflow mesh cover 3-1 of the overflow unit 3, it flows into the overflow mesh cover 3-1 and is discharged outward through the drainage pipe 3-3 downward; therefore, the water body continuously flows into the hatching tank 2 and is discharged from the central position of the hatching tank 2 through the overflow unit 3, forming an effect of circulating water flow, thereby providing a flowing water hatching environment for the floating eggs and ensuring the hatching effect of the floating eggs.

[0034] Due to the continuous circulating flow of the water body and combined with the inverted triangle inclined design of the overflow mesh cover 3-1, it is possible to avoid the problem that the hatched egg membranes adhere to the overflow mesh cover 3-1 and cause the overflow mesh to be blocked. When the incubator is not in use, the overflow unit 3 can be removed, and the water body directly flows out from the drainage port at the bottom 2-2 of the hatching tank, thereby emptying the water in the incubator, which is convenient to operate.

[0035] For a floating-egg incubator provided by the present utility model, the bottom of the drainage pipe 3-3 of the overflow unit 3 is detachably connected to the center of the bottom 2-2 of the hatching tank, the top of the drainage pipe 3-3 is detachably connected to the stainless steel hollowed-out bracket 3-4, and the overflow mesh cover 3-1 and the stainless steel hollowed-out bracket 3-4 are detachably connected, so as to facilitate the inspection, maintenance, disassembly and replacement of each component of the overflow unit 3.

[0036] The present utility model has a simple structure, is easy to operate, detachable, low in cost, small in water consumption, economical and environmentally friendly, and has a good product hatching effect, and has good application value.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
