The water pump 21 delivers purified water to the inlet pipe 8 and sprays it through the spraying device 5. Further, in order to raise the temperature of the spray water and accelerate the incubation of the fish eggs, the temperature control system further comprises a second heating device 27, the second heating device 27 is electrically connected with the signal output end of the main controller 16 through a relay, the second heating device 27 is a heating pipe, and the water in the water storage tank 19 can be heated to a water temperature which is most suitable for the incubation of the viscous fish eggs, for example, 24-30 ℃. In addition, a liquid level alarm 20 and a second sterilization device 22 are further arranged in the water storage tank 19, the second sterilization device 22 is used for killing bacteria in the water storage tank 19, preventing fish eggs from being infected with bacterial diseases in the hatching process, and improving the hatching rate. The liquid level alarm 20 is provided with a high-low water level probe, when the water level is higher than or lower than the normal water level, the liquid level alarm 20 sounds to remind a user that the water tank is full, and the water valve is closed in time so as to avoid wasting water resources, or remind the user of timely water supplementing when the water level in the water storage tank 19 is insufficient, and the normal operation of the device is ensured.
The operation process of the viscous fish egg hatching device is as follows:
before use, the first sterilizing device 7 in the incubator 12 and the second sterilizing device 22 in the water storage tank 19 are opened for 10-15 minutes. Subsequently, the roe loading device 14 attached with the roe is sequentially hung on the hanging bracket 11; then connecting the hanging bracket 11 hung with the fish egg loading device 14 with the upper end of the central shaft 15, covering the sealing cover 3, starting the water circulation system, the fan 2 and the spraying device 5, and setting parameters such as temperature, humidity, incubation time and the like in the incubator 12 on a control screen; after the device operates, the water circulation system inputs heated and sterilized water into the water inlet pipe 8 through the water pump 21, then evenly sprays the heated and sterilized water onto the fish egg loading device 14 through the spraying device 5, then drops from the fish egg loading device 14 to the bottom of the incubator 12 for aggregation, discharges the water to the water filtering device through the water outlet pipe 23 for filtration, and finally enters the water storage tank 19 for heating and sterilization treatment, so that preparation is made for the next round of circulation. During the operation of the device, an operator can observe the development condition of the fish eggs in the incubator 12 through the window 10, and can check parameters such as temperature, humidity and the like on a control screen in real time.
Compared with the prior art, the viscous fish egg hatching device provided by the embodiment of the invention has the following beneficial effects:
(1) The incubator 12 and the water storage tank 19 are added with sterilizing devices, so that bacterial infection is prevented, and the hatching rate of the fish eggs is improved;
(2) The cooperation of the spraying device 5, the central shaft 15 and the suspension bracket 11 can greatly increase the oxygen supply of viscous roes, and avoid the death of fertilized roes due to mutual overlapping and hypoxia;
(3) The temperature control system can effectively maintain the temperature and humidity in the incubator 12, solves the adverse effect caused by weather change and the problem that the fish eggs are infected with saprolegniasis due to low temperature in the incubation process, and further improves the incubation rate of the fish eggs;
(4) The incubation time can be effectively controlled by real-time temperature and humidity adjustment, the development condition of the fish eggs can be checked in real time in the window 10, and the pre-judgment and the change can be timely and accurately made;
(5) The water circulation system not only can effectively realize the circulation of water, but also ensures fresh water quality, less impurities and constant water temperature after filtration, avoids the blockage of the spraying device 5 by impurities in the water, and reduces the risk of the anoxic death of fertilized eggs caused by the adhesion of the impurities on egg membranes;
(6) The detachable connection among the sealing cover 3, the incubator 12 and the water storage tank 19 is convenient for moving, so that the occupied space is reduced.
(7) The embodiment of the invention provides a simple, convenient, efficient and economic viscous fish egg hatching device, which has the advantages of strong pertinence, convenient management, high hatching efficiency and controllable hatching time.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
