Description

Technical Field

[0001] This utility model relates to the field of fish breeding technology, specifically a gradient heating device for promoting the development of fish gonads. Background Technology

[0002] The application of gradient heating devices in promoting fish gonadal development mainly involves simulating temperature changes in the natural environment to influence fish growth and gonadal development. Currently, to improve gonadal development in fish, temperature control is used. Traditional temperature regulation usually involves heating or cooling the entire pond water simultaneously. Such sudden temperature changes can cause great physiological stress to fish, leading to stress responses and affecting their health and growth. Furthermore, if fish do not have sufficient time to adapt to temperature changes, they may experience decreased appetite, reduced activity, or even impaired physiological functions, thus affecting normal gonadal development and reducing the safety of gonadal development. This also indirectly affects the effectiveness of gradient heating devices for promoting fish gonadal development.

[0003] Therefore, it is necessary to develop a gradient heating device to promote the development of fish gonads. Utility Model Content

[0004] The purpose of this invention is to provide a gradient heating device for promoting gonadal development in fish, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gradient heating device for promoting gonadal development in fish, comprising a support, a culture tank mounted on the upper surface of the support, an mounting frame mounted on the top of the support, a rotating shaft rotatably connected to the upper interior of the mounting frame, and a guide groove provided at the top interior of the mounting frame.

[0006] An auxiliary component is installed inside the mounting bracket. The auxiliary component includes a movable base, and a guide seat is installed on the top of the movable base.

[0007] Preferably, a partition is installed on one side of the inside of the cultivation tank, and a heating rod is installed between the partition and the cultivation tank. Through holes are provided on the lower surface of the partition.

[0008] Preferably, a motor A is mounted on the upper part of one outer wall of the mounting bracket, and the output end of the motor A is fixedly connected to one end of the rotating shaft.

[0009] Preferably, the interior of the movable seat is threadedly connected to the outer wall of the rotating shaft, and the outer wall of the guide seat is slidably connected to the interior of the guide groove.

[0010] Preferably, a U-shaped frame is installed at the bottom of the movable seat, a take-up roller is rotatably connected inside the U-shaped frame, and a motor B is installed on one outer wall of the U-shaped frame.

[0011] Preferably, the output end of the motor B is fixedly connected to one end of the take-up roller, and a suspension rope is provided on the outer wall of the take-up roller.

[0012] Preferably, a balance seat is installed at the bottom end of the suspension rope, and a hanger is installed at the bottom of the balance seat.

[0013] Preferably, the hanging frame is located inside a group of the cultivation ponds, and a fishing net is installed inside the hanging frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By fixing the balance seat on the hanger to the end of the rope on the take-up roller, and installing a fishing net in the hollow part of the hanger, fish of the desired gonad development are placed into the fishing net. Motor B lowers the fishing net to the first rearing tank, allowing the fish to initially acclimatize to the temperature. After initial acclimatization, Motor B lifts the fish from the net and moves them to the second rearing tank under the control of Motor A. The temperature in the second rearing tank is higher than the previous one, and this process is repeated until the fish reach the third rearing tank, thus achieving a tiered approach to gonad development. By employing a gradual temperature increase treatment and a step-by-step migration mechanism, fish can have sufficient time to adapt in the initial pond, thereby reducing the physiological stress caused by temperature changes, minimizing stress response, and promoting their healthy growth and gonadal development. This design ensures that fish receive a suitable temperature environment at each migration stage, gradually increasing their growth temperature within a suitable range. This minimizes the negative impact of sudden temperature changes on physiological activities, effectively improving the safety of fish gonadal development and indirectly enhancing the effectiveness of the gradient temperature increase device for promoting fish gonadal development.

[0021] 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.

[0022] This utility model provides the following technical solution: a gradient heating device for promoting gonadal development in fish. Please refer to [link / reference]. Figures 1-4 The system includes a support frame 1, with cultivation tanks 2 mounted on the upper surface of each support frame 1. A partition 201 is installed on one side of the inside of each cultivation tank 2, and a heating rod 202 is installed between the partition 201 and the cultivation tank 2. Through holes 203 are provided on the lower surface of each partition 201. Three sets of cultivation tanks 2 are installed on the support frame 1, and the heating rods 202 in the three sets of cultivation tanks 2 are set to different temperatures from left to right, resulting in different cultivation effects due to the different temperatures achieved by the three sets of cultivation tanks 2. The heating rods 202 are positioned between the partition 201 and the inside of the support frame 1. The rows are separated to prevent fish from coming into contact with the heating rod 202 and posing a risk of injury. A mounting bracket 3 is installed on the top of the bracket 1. A rotating shaft 301 is rotatably connected to the upper part of the mounting bracket 3. A guide groove 302 is opened at the top of the inner side of the mounting bracket 3. A motor A303 is installed on the upper part of one side of the outer wall of the mounting bracket 3. The output end of the motor A303 is fixedly connected to one end of the rotating shaft 301. The rotating shaft 301 on the mounting bracket 3 is fixed to the output end of the motor A303, so that the motor A303 can drive and control the rotating shaft 301 to rotate forward or backward.

[0023] The mounting frame 3 houses auxiliary components, including a movable base 4. A guide seat 401 is mounted on the top of the movable base 4. The interior of the movable base 4 is threadedly connected to the outer wall of the rotating shaft 301. The outer wall of the guide seat 401 is slidably connected to the interior of the guide groove 302. The movable base 4 is threadedly mounted on the outer wall of the rotating shaft 301, and the guide seat 401 is slidably mounted in the guide groove 302 on the mounting frame 3. This allows the rotating shaft 301 to rotate clockwise or counterclockwise, synchronously driving the movable base 4 to move horizontally left or right. A U-shaped frame 402 is mounted at the bottom of the movable base 4. A take-up roller 403 is rotatably connected inside the U-shaped frame 402. A motor B404 is mounted on one outer wall of the U-shaped frame 402. The output end of the motor B404 is fixedly connected to one end of the take-up roller 403. A suspension rope 405 is mounted on the outer wall of the take-up roller 403, and a balance seat 406 is mounted at the bottom end of the suspension rope 405. A hanger 407 is installed at the bottom of the 6, located inside a group of cultivation tanks 2. A fishing net 408 is installed inside the hanger 407. The balance seat 406 on the hanger 407 is fixed to the end of the hanging rope 405 on the winding roller 403. The fishing net 408 is installed in the hollow part inside the hanger 407. Fish with gonad development are placed into the fishing net 408. The fishing net 408 is lowered into the first group of cultivation tanks 2 by motor B404. The fishing net 408 needs to be kept in the cultivation tank 2 and does not need to be removed, so that the temperature in the first group of cultivation tanks 2 can be used for the fish to undergo preliminary adaptation treatment. After the fish have completed the preliminary adaptation, the fish in the fishing net 408 are lifted by motor B404 and then moved to the second group of cultivation tanks 2 by motor A303. The temperature in the second group of cultivation tanks 2 is higher than that in the first group of cultivation tanks 2, and so on, until the fish are moved to the third group of cultivation tanks 2, so as to achieve a gradient temperature increase treatment for the gonad development of the fish.

[0024] Working principle: When using this invention, three sets of cultivation tanks 2 are installed on the bracket 1, and the heating rods 202 in the three sets of cultivation tanks 2 are set to different temperatures from left to right, so that the three sets of cultivation tanks 2 reach different temperatures and thus have different cultivation effects. At the same time, the installation positions of the heating rods 202 are separated by the partition 201 to prevent fish from coming into contact with the heating rods 202 and posing a risk of injury. By fixing the rotating shaft 301 on the mounting bracket 3 to the output end of the motor A303, the motor A303 can drive and control the rotating shaft 301 to rotate forward or backward. By threading the movable seat 4 onto the outer wall of the rotating shaft 301, and sliding the guide seat 401 on the movable seat 4 into the guide groove 302 on the mounting frame 3, the rotating shaft 301 can rotate forward or backward, synchronously driving the movable seat 4 to move horizontally to the left or right. By fixing the balance seat 406 on the hanger 407 to the end of the hanging rope 405 on the take-up roller 403, and setting the fishing net 408 in the hollow part inside the hanger 407, fish with gonad development can be placed into the fishing net 408, and the motor B404 will control the movement. The fishing net 408 is lowered into the first rearing pond 2, and it needs to remain in the pond 2 without being removed. This allows the fish to undergo initial acclimatization to the temperature in the first rearing pond 2. After the fish have acclimatized, motor B404 lifts the fish from the fishing net 408, and motor A303 controls their movement to the second rearing pond 2. Since the temperature in the second rearing pond 2 is higher than that in the first rearing pond 2, this process is repeated until the fish reach the third rearing pond 2. This achieves a gradient temperature increase for the fish's gonadal development. Simultaneously, through this gradual migration mechanism, the fish have sufficient time to acclimatize in the initial ponds, reducing the physiological stress caused by temperature changes, minimizing stress responses, and promoting healthy growth and gonadal development. This design ensures that the fish receive a suitable temperature environment at each migration stage, gradually increasing their growth within a suitable temperature range. This minimizes the negative impact of sudden temperature changes on physiological activities, effectively improving the safety of gonadal development and indirectly enhancing the effectiveness of the gradient temperature increase device for promoting gonadal development.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
