Description

Technical Field

[0001] This utility model relates to the field of temperature control device technology, specifically a temperature control device for incubating golden trout eggs. Background Technology

[0002] As a cold-water salmonid fish, the hatching of golden trout eggs requires stringent environmental conditions, especially the control of temperature stability, water quality, and water flow, which directly affect the hatching rate and the survival rate of fry.

[0003] During the hatching process of golden trout eggs, impurities such as egg mucus, metabolic waste, and a small amount of uneaten food are produced. If not cleaned in time, these impurities can easily clog the filter device and breed bacteria. Most existing devices have fixed filter plates, which require stopping the machine for disassembly during cleaning. This is not only cumbersome but also causes sudden changes in water temperature, interfering with the hatching environment. In addition, some devices lack a targeted impurity collection structure, and impurities can easily be mixed back into the hatching area with the water flow during cleaning, polluting the water quality. Therefore, this utility model proposes a temperature control device for golden trout egg hatching to solve the above problems. Utility Model Content

This achieves uniform water temperature, automatic removal of impurities, and avoids localized high temperatures and sudden changes in water temperature.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a temperature control device for incubating golden trout eggs, which has the following beneficial effects:

[0016] 1. This utility model uses a reciprocating screw to drive a scraper to move back and forth along the surface of the filter plate. Combined with the elastic pressure of the spring, it can automatically remove impurities such as mucus and residual bait from the filter plate without stopping the machine to disassemble the filter plate. At the same time, the impurities are pushed by the scraper to the collection boxes on both sides. The operator can simply pull out the collection boxes to complete the cleaning.

Detailed Implementation

[0023] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0024] This utility model provides a technical solution for a temperature control device for incubating golden trout eggs:

[0025] Please see Figure 1-4 A temperature control device for hatching golden trout eggs includes a water tank 1, an incubation box 2 fixedly connected to the upper end of the water tank 1, an open end face of the incubation box 2 with a cover plate 3 installed at the open end face, a partition plate 10 fixedly connected to the inner wall of the incubation box 2 with a heating wire installed on one side of the partition plate 10, an overflow channel with a baffle plate 11 on the end face of the incubation box 2, a filter channel with a filter plate 5 installed on the filter channel, a water guide plate 4 installed at the upper end of the water tank 1 with one end of the water guide plate 4 located at the overflow channel and the other end located above the filter plate 5, two sets of collection boxes 6 slidably connected in the overflow channel and located on both sides of the filter plate 5 respectively, and a cleaning mechanism is provided at the upper end of the water tank 1.

[0026] The cleaning mechanism is used to clean the impurities filtered out from the end face of the filter plate 5;

[0027] Furthermore, by setting up an independent incubation box 2 at the top of the water tank 1 and using a partition 10 to isolate the heating wire from the fish egg incubation area, direct contact between the heating element and the fish eggs can be avoided, preventing localized high-temperature damage. The combined design of the overflow trough and the water guide plate 4 allows water to flow through the filter plate 5 before entering the incubation box 2, effectively intercepting impurities such as mucus and uneaten food, reducing the risk of filter clogging. The sliding connection structure of the collection box 6 allows for easy removal and cleaning without stopping the machine to disassemble the filter plate 5, avoiding interference with the incubation environment caused by sudden changes in water temperature.

[0028] The cleaning mechanism includes two sets of side plates 12 fixedly connected to the end face of the water tank 1. A reciprocating screw 13 is rotatably connected between the two sets of side plates 12. A screw sleeve 14 is rotatably installed on the outer wall of the reciprocating screw 13. A slide rod 20 is slidably connected to the outer wall of the screw sleeve 14. A scraper 16 is fixedly connected to the end of the slide rod 20, and the scraper 16 is slidably connected to the outer wall of the filter plate 5.

[0029] Furthermore, the design of the reciprocating screw 13 and the screw sleeve 14 allows the scraper 16 to move automatically back and forth along the surface of the filter plate 5, thereby achieving continuous cleaning of impurities.

[0030] One end of the slide rod 20 is fixedly connected to a limiting block 17, and the radius of the limiting block 17 is larger than the radius of the slide rod 20. A spring 18 is sleeved on the outer wall of the slide rod 20, and the two ends of the spring 18 are fixedly connected to the limiting block 17 and the outer wall of the lead screw sleeve 14, respectively.

[0031] Furthermore, the spring 18 ensures that the scraper 16 maintains elastic contact with the filter plate 5 during the cleaning process, which can effectively remove stubborn impurities and prevent rigid contact from damaging the filter plate 5.

[0032] A limiting rod 15 is fixedly connected between the two sets of side plates 12, and a screw sleeve 14 is slidably connected to the outer wall of the limiting rod 15. A water pump 7 is fixedly connected to the outer wall of the water tank 1, and one end of the pump is connected to the inside of the water tank 1.

[0033] Furthermore, the setting of the limit rod 15 restricts the rotational freedom of the lead screw sleeve 14, so that it can only move along the axial direction of the reciprocating lead screw 13, ensuring the stability of the linear motion trajectory of the scraper 16.

[0034] The other end of the water pump 7 is fixedly connected to a connecting pipe 9, and the end face of the water tank 1 is fixedly connected to a transmission box 8. The other end of the connecting pipe 9 is connected to the inside of the transmission box 8, and the other end of the transmission box 8 is fixedly connected to a liquid guide pipe, which is connected to the inside of the incubator 2.

[0035] The transmission box 8 converts the power of the water pump 7 into the rotational motion of the rotating rod. Through the interaction between the rotating plate 19 and the water flow, energy is efficiently transferred. The design of the connection path between the connecting pipe 9 and the liquid guide pipe ensures that the water flow is fully mixed before entering the incubator 2.

[0036] A rotating rod is rotatably connected inside the transmission box 8. A rotating plate 19 is provided on the outer circumference of the rotating rod. The rotating rod is coaxially and fixedly connected to the reciprocating lead screw 13.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] When using the device, the operator first places the golden trout eggs into the incubation tank 2 and covers it with the lid 3 to isolate it from external environmental interference. After starting the device, the heating wire begins to work, transferring heat to the water in the incubation tank 2 through the partition 10. Because the partition 10 separates the heating wire from the egg incubation area, it avoids the problem of excessively high local temperatures caused by the heating element directly contacting the eggs, allowing the water temperature to rise slowly and evenly to a suitable range for incubation. This solves the problem of embryo damage caused by localized high temperatures in traditional devices.

[0039] Meanwhile, the water pump 7 on the outer wall of the water tank 1 starts, transporting the water in the water tank 1 to the transmission box 8 through the connecting pipe 9. After the water flows into the transmission box 8, it impacts the rotating plate 19 on the outer wall of the rotating rod, causing the rotating rod to rotate. Since the rotating rod is coaxially fixed with the reciprocating screw 13, the reciprocating screw 13 rotates together with the rotating rod between the two sets of side plates 12, thereby driving the screw sleeve 14 on the outer wall to move axially along the reciprocating screw 13. During this process, the limiting rod 15 restricts the rotation tendency of the screw sleeve 14, ensuring that it only makes linear motion, so that the scraper 16 connected to the end of the slide rod 20 can stably adhere to the surface of the filter plate 5.

[0040] The spring 18 on the outer wall of the slide bar 20 is always in a slightly compressed state, applying continuous pressure to the scraper 16 through the limiting block 17. This ensures that the scraper 16 can effectively scrape off impurities such as mucus and residual bait on the filter plate 5, while avoiding damage to the filter plate 5 caused by rigid contact. As the lead screw sleeve 14 moves back and forth, the scraper 16 pushes the impurities on the surface of the filter plate 5 to both sides, and finally falls into the collection box 6 in the overflow trough. The operator can directly pull out the collection box 6 for cleaning without disassembling the filter plate 5, effectively avoiding the problem of sudden water temperature changes caused by traditional cleaning methods.

[0041] When the water in incubator 2 needs to be circulated and refreshed, the baffle 11 is opened, and the water flows through the overflow channel to the guide plate 4, and then flows gently along the guide plate 4 to the filter plate 5. The water filtered by the filter plate 5 flows back to the water tank 1 to complete the purification, and then is sent back to the incubator 2 through the liquid guide pipe to form a stable water circulation system. This design not only ensures continuous water purification, but also avoids local temperature fluctuations caused by the direct impact of water flow on the fish eggs, solving the problem of uneven water temperature in traditional devices.

[0042] In summary, this device achieves uniform heating through the partition 10, automatically removes impurities using a cleaning mechanism, and ensures stable water temperature and clean water quality through a water circulation system. It eliminates the need for frequent manual intervention, minimizing external interference with the hatching environment and effectively improving the hatching stability and survival rate of golden trout eggs.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
