Description

Technical Field

[0001] The invention belongs to the technical field of fishery breeding tools, and in particular relates to an automatic micro water tank. Background Art

[0002] At present, most farmers adopt pond farming method when raising fry. As a traditional fry farming method, it is necessary to first prepare a pond as a breeding site during the operation; the second is to fertilize the water to make the water nutrient-rich, which is more conducive to the development and growth of the fry; the next step is to put in the fry. The primary breeding bait for the fry is egg yolk. After a period of development and growth, the fry in this period are fed with soy milk as bait. In the subsequent growth process of the fry, fish feed is gradually added, and the proportion of fish feed gradually increases to meet the needs of the fry to obtain more nutrients.

[0003] In this process, large-scale automated water flow troughs are used as auxiliary means of breeding. Their disadvantages are: first, they cause great pollution to the environment, especially the discharge of breeding tail water. In order to achieve the national emission standards for breeding tail water, many large-scale automated water flow troughs use a large amount of chemicals to purify the water body, which causes a certain impact on the environment while purifying the breeding tail water. In addition, there is a lot of organic matter accumulated at the bottom of the large-scale automated water flow troughs, which is not easy to collect and centrally treat, causing the water quality to deteriorate. Second, the temperature is uncontrollable. Since the water used in the large-scale automated water flow troughs is natural flowing water, its temperature is mainly affected by the external natural environment. For example, direct sunlight will cause the temperature of the pond to rise, and artificial temperature intervention facilities such as the construction of plastic sheds are limited by the large area of ​​the pond, which requires a lot of financial, human and material resources. In actual operation, the feasibility is not great.

[0004] Therefore, we designed an automated micro-flow trough for the breeding of fish fry. Because the depth of the flow trough is relatively shallow, the amount of water in the flow trough is relatively small, which can more easily control the temperature, dissolved oxygen and other physiological conditions of the water body. However, this type of flow trough also has certain usage problems in daily breeding. That is, because the depth of the flow trough is limited, birds can more easily catch the fry in the flow trough, thereby reducing the survival rate of the fry. Summary of the Invention

[0005] The purpose of the present invention is to provide an automated micro water tank, which aims to reduce the difficulty of fry breeding and improve the survival rate of fry breeding.

[0006] The technical solution adopted by the present invention to solve its technical problems is: an automated micro-flow trough, including a controller and a micro-flow trough body, the cross-section of the micro-flow trough body in the length direction is trapezoidal, the micro-flow trough body is fixed with a fixed block at the top of its length direction, the number of the fixed blocks is two, a swing rod is provided between the two fixed blocks, the swing rod is rotatably connected to the fixed block, and a baffle is provided in the width direction of the micro-flow trough body, the number of the baffle is two, and the baffle is fixedly connected to the swing rod.

[0007] Optionally, the shielding plate is made of transparent plastic.

[0008] Optionally, a light-transmitting groove is provided on the surface of the shielding plate.

[0009] Optionally, a natural water inlet pipe is fixed to the outer surface of the micro-flow trough body, and the natural water inlet pipe is connected to an external water pump. The inner surface of the micro-flow trough body is provided with an inclined nozzle, and the inclined nozzle is evenly arranged along the length direction of the micro-flow trough body. The inclined nozzle is connected to the natural water inlet pipe, and the swing plate swings when the inclined nozzle sprays water intermittently.

[0010] Optionally, an arc-shaped stirring rod is fixed on the shielding plate, and the arc-shaped stirring rod is evenly arranged along the length direction of the micro water trough body.

[0013] Optionally, a buffer pad is fixed to the bottom of the micro water trough body.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. In the automated micro-water tank described in the present invention, the shielding plate can protect the fry in the micro-water tank body, prevent birds from entering the micro-water tank body and preying on the fry, thereby improving the survival rate of the fry farming. Moreover, because the shielding plate is fixed to the swing rod, and the swing rod is rotatably connected to the fixed block, when a bird falls onto the shielding plate, the shielding plate will rotate with the rotation of the swing rod, making it impossible for the bird to stand stably on the shielding plate, and thus unable to accurately prey on the fry in the micro-water tank body. At the same time, the movement of the shielding plate can also drive away the birds, thereby improving the survival rate of the fry farming.

When the water sprayed from the oblique nozzle drives the swing rod to swing, the arc-shaped stirring rod can stir the water in the micro water tank body, thereby further increasing the dissolved oxygen content of the water in the micro water tank body, thereby further improving the survival rate of the fry.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to solve the problems raised in the background art, the present invention has designed a respiratory training device. The main concept of the present invention is to design the respiratory training device to be retractable, thereby reducing the volume of the respiratory training device in the prior art while improving the convenience of cleaning and disinfection. The specific structure and operating principle of the respiratory training device are as follows:

[0024] like Figure 1-3 As shown, this type of automated micro-flow water tank includes a controller and a micro-flow water tank body 1. The cross-section of the micro-flow water tank body 1 in the longitudinal direction is trapezoidal. A fixed block 2 is fixed to the top of the micro-flow water tank body 1 in the longitudinal direction. The number of the fixed blocks 2 is two. A swing rod 3 is provided between the two fixed blocks 2. The swing rod 3 is rotatably connected to the fixed block 2. A shielding plate 4 is provided in the width direction of the micro-flow water tank body 1. The number of the shielding plates 4 is two. The shielding plates 4 are fixedly connected to the swing rod 3.

[0025] Specifically, the shielding plate 4 is made of transparent plastic;

[0026] Specifically, a light-transmitting groove 41 is provided on the surface of the shielding plate 4;

[0027] Specifically, the size of this automated micro-flow trough is about 34 cm in width, 23 cm in width at the bottom, 26 cm in height and 590 cm in length. Because the micro-flow trough body 1 is shallow, the amount of water in the trough is small, and the depth of the water is generally controlled at 18-20 cm, which makes it easier to control the temperature, dissolved oxygen and other physiological conditions of the water body. Before the fry are cultured in the micro-flow trough body 1, the fry are first placed in the micro-flow trough body 1, and then one end of the swing rod 3 fixed with the baffle 4 is inserted into the rotating hole in the fixed block 2, and then the other end of the swing rod 3 is placed in the rotating hole of another fixed block 2 so that the swing rod 3 can rotate. Of course, the swing rod 3 can also be placed directly first, and then the baffle 4 is rotated to place the fry into the micro-flow trough body 1;

[0028] Then, when the fry are cultured in the micro-flow trough body 1, the shielding plate 4 is made of transparent plastic and has a light-transmitting groove 41 on its surface. On the one hand, it meets the light required for daily culture of the fry, and on the other hand, it is convenient for the culture staff to observe the production of the fry in the micro-flow trough body 1 at all times. When it is necessary to feed the fish, the shielding plate 4 can be rotated to put the fish food into the micro-flow trough body 1;

[0029] At the same time, the shielding plate 4 can protect the fry in the micro-flow trough body 1, prevent birds from entering the micro-flow trough body 1 and preying on the fry, thereby improving the survival rate of fry farming. Moreover, because the shielding plate 4 is fixed to the swing rod 3, and the swing rod 3 is rotatably connected to the fixed block 2, when a bird falls on the shielding plate 4, the shielding plate 4 will rotate with the rotation of the swing rod 3, that is, the bird falls on the shielding plate 4 on one side of the swing rod 3, and the shielding plate 4 on one side will move downward, making it impossible for the bird to stand stably on the shielding plate 4, and thus unable to accurately prey on the fry in the micro-flow trough body 1. At the same time, the movement of the shielding plate 4 can also drive away the birds, thereby improving the survival rate of fry farming.

[0030] When birds stand on the edge of the micro-flow trough body 1, this can be done by controlling the distance between the shielding plate 4 and the edge of the micro-flow trough body 1 to prevent the birds from preying on the fry in the micro-flow trough body 1. For example, the distance between the shielding plate 4 and the edge of the micro-flow trough body 1 can be controlled to 2-4 cm, and it will not affect the normal rotation of the shielding plate 4.

[0031] Specifically, a natural water inlet pipe 5 is fixed on the outer surface of the micro-flow trough body 1, and the natural water inlet pipe 5 is connected to an external water pump, which is controlled by a controller. An inclined nozzle 51 is provided on the inner surface of the micro-flow trough body 1, and the inclined nozzle 51 is evenly arranged along the length direction of the micro-flow trough body 1. The inclined nozzle 51 is connected to the natural water inlet pipe 5, and the inclined nozzle 51 causes the swing plate to swing when it sprays water intermittently.

[0032] Specifically, arc-shaped stirring rods 6 are fixed on the shielding plate 4 , and the arc-shaped stirring rods 6 are evenly arranged along the length direction of the micro-flow tank body 1 .

[0033] In order to further prevent birds from preying on the fry in the micro-flow trough body 1, we have also carried out the above design. The advantage of this design is that, first, the water pump is controlled by the controller to intermittently pump natural water into the natural water inlet pipe 5, and then the natural water is intermittently sprayed out through the inclined nozzle 51. The impact force of the sprayed water is used to drive the swing plate to swing intermittently. The intermittent swing of the swing plate can drive the birds away, further preventing the birds from preying on the fry in the micro-flow trough body 1. At the same time, when the sprayed water falls into the micro-flow trough body 1, the content of dissolved oxygen in the water can also be increased, thereby improving the survival rate of the fry, while reducing the use time of the oxygenator and the aerator, and replenishing the natural water to the micro-flow trough body 1;

[0034] The design of the arc-shaped stirring rod can cooperate with the oblique nozzle 51. When the water sprayed by the oblique nozzle 51 drives the swing rod 3 to swing, the arc-shaped stirring rod can stir the water in the micro-flow tank body 1, thereby further increasing the dissolved oxygen content of the water in the micro-flow tank body 1, thereby further improving the survival rate of the fry and reducing the use time of the oxygenator and the aerator.

[0035] In actual arrangement, a hole for installing the inclined nozzle 51 can be reserved when the micro-flow trough body 1 is produced. The position of the hole is controlled at 23-24 cm of the height of the micro-flow trough body 1. Then, after installing and fixing the inclined nozzle 51, the natural water inlet pipe 5 can be connected to the inclined nozzle 51.

[0036] Specifically, one end of the micro-flow tank body 1 is connected to an artificial treatment water source inlet pipe 7 in the longitudinal direction, and the artificial treatment water source inlet pipe 7 is connected to an external water pump, which is also controlled by the controller;

[0037] Specifically, the micro water tank body 1 has a water outlet 8 at the other end in the longitudinal direction;

[0038] Because the artificially treated water source can conveniently and better control a series of physiological conditions such as dissolved oxygen, water temperature and microorganisms, when it is necessary to supplement the artificially treated water source in the micro-flow trough body 1, the water pump can be controlled by the controller so that the water pump pumps the water source after the artificial treatment of the water source into the micro-flow trough body 1 through the artificial treatment water source inlet pipe 7. When it is necessary to drain the micro-flow trough body 1, such as changing the water, or when there is too much water in the micro-flow trough body 1, the water outlet 8 can be opened to drain the water. Therefore, a baffle and a valve can be set at the water outlet 8. The purpose of the baffle is to prevent the fry from flowing out of the water outlet, and the valve is used to close or open the water outlet 8. Therefore, the valve can be an electrically controlled valve controlled by the controller, or a manual valve can also be used.

[0039] In other embodiments, the water outlet 8 may not be provided, and the water may be directly pumped out by a water pump. At the same time, in order to facilitate knowing the temperature of the water in the micro-flow trough body 1, a thermometer is provided in the micro-flow trough body 1 to facilitate controlling the water temperature in the micro-flow trough body 1.

[0040] Specifically, a buffer pad 9 is fixed to the bottom of the micro water trough body 1 . The purpose of the buffer pad 9 is to reduce the impact on the micro water trough body 1 when it is placed on the ground, thereby increasing the service life of the micro water trough body 1 .
