Abstract

This utility model relates to the field of fish farming technology and discloses a constant temperature box for raising and nurturing freshwater fish fry. The transparent box has a partition plate fixedly installed inside. The bottom of the partition plate is sealed to the exhaust pipe of the oxygen supply pump. By pulling open the bottom of the inner mesh plates on both sides, the top of the inner mesh plate slides down along the strip ball groove through the connecting ball until the bottom of the inner mesh plate presses against the limiting strip and stops. At this time, the internal movement space of the inner shell of the eye hole is reduced to a trapezoidal shape. The inner shell of the eye hole is pulled up by the handle. The surrounding pneumatic rods provide auxiliary force for pulling up the inner shell of the eye hole. As the inner shell of the eye hole rises, its internal movement space is reduced again, thereby realizing the purpose of gathering the fish fry and facilitating the subsequent fishing net catching. At the same time, the inner shell of the eye hole is connected to the pneumatic rod by bolts, so the entire inner shell of the eye hole can be lifted out of the transparent box, thereby realizing the catching of all the fish fry and facilitating the direct change of the fish fry breeding site.

Description

Technical Field

[0001] This utility model relates to the field of fish farming technology, specifically a constant temperature box for raising and breeding freshwater fish. Background Technology

[0002] With the development of the fishery industry, more and more fish farm owners are choosing to raise freshwater fish on a large scale. In the process of freshwater fish farming, the hatching of juvenile fish is very important. In order to improve the hatching success rate of fry, many people have started to use hatching tanks to hatch freshwater fish fry.

[0003] Conventional fry rearing boxes are made of transparent acrylic panels, allowing for easy monitoring of the fry's growth. In cold winter weather, the water temperature drops, making it unsuitable for fry growth. Therefore, heating wires are installed in the fry rearing boxes to regulate the water temperature, thus facilitating fry growth. However, as the fry grow, they need to be harvested and transferred to larger rearing ponds. The conventional method is to directly discharge the water and fry into the rearing pond together, but this method can cause injury to the fry due to water flow. If fishing nets are used to catch the fry in the fry rearing boxes, the large size of the boxes means that the fry will swim around as the nets swing, resulting in low capture efficiency.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a constant temperature box for freshwater fish breeding and raising, which has the following beneficial effects:

[0015] 1. This freshwater fish fry breeding incubator uses a temperature sensor to monitor the water temperature in real time. When the water temperature is low, the controller and touch panel drive the heating wire to raise the water temperature. When the water temperature reaches the suitable temperature for the fry, the temperature sensor transmits a signal to the controller and touch panel, which then drives the heating wire to stop. At the same time, the controller and touch panel can also drive the oxygen pump to operate. The oxygen pump delivers gas from the filter element on the air plate, which forms many small bubbles. This facilitates oxygen delivery and pushes the water at the bottom to rise, ensuring uniform water temperature mixing and preventing uneven temperatures. This maintains a constant water temperature, which is beneficial for the growth of the fry.

[0016] 2. This constant temperature incubator for freshwater fish fry rearing works by pulling open the bottom of the inner mesh panels on both sides. The top of the inner mesh panels slides down the strip-shaped ball groove via connecting balls until the bottom of the inner mesh panels presses against the limiting strip and stops. At this point, the internal movement space of the inner shell of the eye hole shrinks into a trapezoidal shape. By pulling up the inner shell of the eye hole with the handle, the surrounding pneumatic rods provide auxiliary force for pulling up the inner shell of the eye hole. As the inner shell of the eye hole rises, its internal movement space shrinks again, thereby achieving the purpose of gathering fish fry and facilitating subsequent fishing net capture. At the same time, the inner shell of the eye hole is connected to the pneumatic rods by bolts. The bolts can be removed to lift the entire inner shell of the eye hole out of the transparent box, thereby achieving the capture of all fish fry and facilitating the direct change of the fish fry rearing site.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 A constant temperature box for raising and nurturing freshwater fish fry includes a base plate 1 and a frame 2. The base plate 1 and the frame 2 are fixedly installed together by a connecting pipe 3. A transparent box 4 is movably installed inside the frame 2. The transparent box 4 is made of transparent glass. A partition plate 5 is fixedly installed inside the transparent box 4, dividing the transparent box 4 from top to bottom into a nurturing room and an equipment room. A cavity 6 is opened inside the partition plate 5, and a heating wire 7 is installed inside the cavity 6. The heating wire 7 can be used to raise the temperature of the water in the transparent box 4, which is suitable for the growth of fish fry.

[0027] Please see Figure 2-3 The bottom of the partition plate 5 is sealed to the exhaust pipe of the oxygen pump 8, which is placed in the equipment room. An air pipe 9 is fixedly installed on the side of the oxygen pump 8, and the other end of the air pipe 9 extends to the outside of the transparent box 4. A one-way valve 10 is embedded inside the exhaust pipe of the oxygen pump 8 to prevent water from flowing back into the oxygen pump 8. An air plate 11 is fixedly installed on the exhaust pipe of the oxygen pump 8. A filter element 12 is embedded in the through hole on the surface of the air plate 11. The oxygen pump 8 draws in outside air and sprays it out through the filter element 12 on the air plate 11. The gas forms bubbles, thereby oxygenating the water.

[0028] Please see Figure 2-3 A drain valve 13 is fixedly installed on the side of the transparent box 4 to drain all the water in the box. It can also be connected to an external water treatment plant to treat the water. A limit frame 14 is fixedly installed on the inner wall of the transparent box 4. A protruding frame 15 is provided on the top of the limit frame 14. A handle 16 is fixedly installed on the top of the protruding frame 15. An eye hole inner shell 17 is fixedly installed on the bottom of the protruding frame 15. The eye hole inner shell 17 is placed in the seedling room. A limit strip 18 is fixedly installed on the inner bottom wall of the eye hole inner shell 17. Inner mesh plates 19 are slidably installed on both sides of the eye hole inner shell 17.

[0029] Please see Figure 4-7A shaft 20 is fixedly installed in the grooves at the top and bottom of the inner mesh plate 19. A bushing 21 is movably fitted on the outer side of the upper shaft 20. A connecting ball 22 is fixedly installed on the side of the bushing 21. The connecting ball 22 is slidably connected in the interior of the strip-shaped ball groove 23, which is formed on the inner wall of the eye hole inner shell 17. Pulling the bottom of the inner mesh plate 19 open and pressing it against the limiting strip 18 will cause the inner mesh plate 19 to be tilted, thereby reducing the internal space of the eye hole inner shell 17.

[0030] Please see Figure 4-7 A pneumatic rod 24 is embedded inside the connecting pipe 3. The output end of the pneumatic rod 24 is detachably connected to a connecting plate 25 by bolts. The connecting plate 25 is connected to the protruding frame 15 by bolts. The pneumatic rod 24 can assist the inner shell 17 of the eye hole to rise, thereby limiting the movement space of the entire inner shell 17 of the eye hole.

[0031] Please see Figure 1-7 A temperature sensor 26 is embedded in the surface of the partition plate 5. The temperature sensor 26 is connected to the controller and touch panel via signal transmission. The heating wire 7 and the oxygen pump 8 are electrically connected to the controller and touch panel. The controller and touch panel are mounted on the frame 2. The oxygen pump 8, temperature sensor 26, controller, and touch panel are all references to existing technologies, and will not be described in detail in this application. When using them, the preferred method can be selected under the premise of meeting the driving conditions.

[0032] Working principle: During use, the temperature sensor 26 can monitor the water temperature in real time. If the water temperature is low, the controller and touch panel drive the heating wire 7 to run, and the heating wire 7 will raise the water temperature. When the water temperature is raised to a suitable temperature for the fish fry, the temperature sensor 26 will transmit a signal to the controller and touch panel, and the controller and touch panel will drive the heating wire 7 to stop running.

[0033] Meanwhile, the controller and touch panel can also drive the oxygen pump 8 to run. The oxygen pump 8 delivers gas from the filter element 12 on the air plate 11, which will then form many small bubbles. This facilitates the delivery of oxygen and pushes the bottom water upward, thereby ensuring that the water temperature is mixed evenly and that there is no problem of uneven water temperature. This ensures a constant water temperature and facilitates the growth of fish fry.

[0034] By pulling open the bottom of the inner mesh plates 19 on both sides, the top of the inner mesh plates 19 slides down along the strip-shaped ball groove 23 via the connecting ball 22 until the bottom of the inner mesh plates 19 presses against the limiting strip 18 and stops. At this time, the internal moving space of the inner shell 17 of the eye hole shrinks into a trapezoidal shape. The inner shell 17 of the eye hole is pulled up by the handle 16, and the surrounding pneumatic rods 24 provide auxiliary force for pulling up the inner shell 17 of the eye hole. As the inner shell 17 of the eye hole rises, its internal moving space shrinks again, thereby achieving the purpose of gathering fish fry and facilitating subsequent fishing net catching.

[0035] Meanwhile, the inner shell 17 of the eye hole is connected to the pneumatic rod 24 by bolts. The bolts can be removed to lift the entire inner shell 17 of the eye hole out of the transparent box 4, thereby enabling the harvesting of all the fish fry and facilitating the direct replacement of the fish fry breeding site.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
