Description

Technical Field

[0001] This utility model relates to the field of leech farming technology, and in particular to a device for protecting the broad-bodied golden leech during winter. Background Technology

[0002] The broad-bodied golden leech, an aquatic organism with significant medicinal and economic value, has attracted considerable attention in the aquaculture industry. However, it is quite sensitive to its living environment, especially water temperature, and low temperatures in winter can severely impact its survival and feeding.

[0003] In traditional broad-bodied golden thread leech farming, controlling water temperature in winter has always been a challenge. In natural environments, as air temperature drops in winter, water temperature also decreases. When the temperature falls below the range suitable for the survival of broad-bodied golden thread leeches, their activity level weakens, their appetite decreases, and they may even die in large numbers. Currently, although some devices exist for water heating, these devices generally suffer from uneven heating. Some devices can only heat localized areas of the water, resulting in significant temperature differences between different locations. Broad-bodied golden thread leeches cannot survive in suitable temperature environments, failing to meet the actual needs of broad-bodied golden thread leech farming. Therefore, how to solve the above problems needs to be considered. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for protecting the broad-bodied golden leech during winter. When in use, the device utilizes a heating air pump in conjunction with a moving mechanism to evenly inject heated air into the water, thereby effectively and uniformly raising the water temperature and preventing the low water temperature in winter from affecting the survival or feeding desire of the broad-bodied golden leech.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for protecting the overwintering of broad-bodied golden leeches includes a breeding pond, the upper end of which is fixedly connected to a U-shaped frame;

[0007] The heating mechanism includes a movable plate, a rotating tube rotatably connected to the lower end of the movable plate, the lower end of the rotating tube being sealed, and exhaust holes on both sides of the lower end of the rotating tube. A heating air pump is fixedly connected to the right side of the movable plate. The upper end of the rotating tube passes through the movable plate and is connected to the exhaust end of the heating air pump via a rotary joint. A moving mechanism is used to move the rotating tube. A rotating mechanism is used to rotate the rotating tube to improve the uniformity of gas supply.

[0008] Preferably, the moving mechanism includes a reciprocating lead screw rotatably connected between the inner walls of the left and right sides of the U-shaped frame, a slider threadedly connected to the reciprocating lead screw, the upper end face of the slider being slidably connected to the inner top of the U-shaped frame, and the front side of the slider being fixedly connected to the rear side of the moving plate.

[0009] Preferably, a first motor is installed on the right side of the U-shaped frame, and the output shaft of the first motor passes through the vertical part of the U-shaped frame on the U side and is fixedly connected to the right end of the reciprocating lead screw.

[0010] Preferably, the rotating mechanism includes a second motor mounted on the upper end of the movable plate, and synchronous pulleys are mounted on both the output shaft of the second motor and the rotating tube, and the two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, two connecting rods are symmetrically fixedly connected to the lower end of the movable plate, and the lower ends of the two connecting rods are jointly fixedly connected to a protective box. The lower end of the rotating tube penetrates the inner top of the protective box and extends into the interior of the protective box. Multiple diversion holes are provided on the side wall of the protective box.

[0012] Preferably, the rotating tube is fixedly connected to multiple disintegration rods on the outside of the protective box.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. By blowing hot air out through a heated air pump and moving the rotating tube back and forth, the hot air is discharged from different positions in the breeding pond, expanding the heating range, avoiding excessive local water temperature differences, achieving uniform and efficient water heating, and ensuring a suitable growth environment for the broad-bodied golden leech.

[0015] 2. The rotating tube rotates while moving, allowing the bubbles formed by the hot air to enter the water more evenly, enhancing the contact effect between the hot air and the water, preventing the bubbles from concentrating, and ensuring that all areas of the water can fully absorb heat, thus improving the heating effect.

[0016] 3. The rotating tube drives the dispersing rod to break up the floating air bubbles, turning large bubbles into smaller ones and increasing the heat exchange area between the bubbles and the water. The diversion holes on the side wall of the protective box further squeeze and break the bubbles, further enhancing the heat exchange effect and improving the heating efficiency.

[0017] 4. The protective box effectively prevents leeches from getting too close to the heat source, preventing them from being damaged by excessively high water temperatures. It also prevents damage to the leeches when the dispersing rod is rotated, ensuring the safety of the leeches during the heating process. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-5 A device for protecting the overwintering of broad-bodied golden leeches includes a breeding pond 1, with a U-shaped frame 2 fixedly connected to the upper end of the breeding pond 1;

[0026] The system also includes a heating mechanism, which includes a movable plate 6. The lower end of the movable plate 6 is rotatably connected to a rotating tube 11. The rotation is achieved by a bearing. The lower end of the rotating tube 11 is sealed. Both sides of the lower end of the rotating tube 11 are provided with exhaust holes 15. A heating air pump 8 is fixedly connected to the right side of the movable plate 6. It consists of an air pump and a heating element (such as an electric heating wire) and can blow out hot air. The upper end of the rotating tube 11 passes through the movable plate 6 and is connected to the exhaust end of the heating air pump 8 through a rotary joint 9.

[0027] The system also includes a moving mechanism for moving the rotating tube 11. The moving mechanism includes a reciprocating screw 3 rotatably connected between the inner walls of the left and right sides of the U-shaped frame 2. A slider 5 is threaded onto the reciprocating screw 3. The upper end face of the slider 5 is slidably connected to the inner top of the U-shaped frame 2. The front side of the slider 5 is fixedly connected to the rear side of the moving plate 6. A first motor 4 is installed on the right side of the U-shaped frame 2. The output shaft of the first motor 4 passes through the vertical part of the U-side of the U-shaped frame 2 and is fixedly connected to the right end of the reciprocating screw 3.

[0028] It also includes a rotating mechanism, which is used to rotate the rotating tube 11 to improve the uniformity of gas supply. The rotating mechanism includes a second motor 10 installed on the upper end of the moving plate 6. The output shaft of the second motor 10 and the rotating tube 11 are both equipped with synchronous pulleys 17. The two synchronous pulleys 17 are connected by a synchronous belt 18.

[0029] Two connecting rods 12 are symmetrically fixedly connected to the lower end of the movable plate 6. The lower ends of the two connecting rods 12 are fixedly connected to a protective box 13. The lower end of the rotating tube 11 passes through the inner top of the protective box 13 and extends into the interior of the protective box 13. Multiple diversion holes 19 are opened on the side wall of the protective box 13. Multiple dispersing rods 16 are fixedly connected to the rotating tube 11 inside the protective box 13. The rotation of the dispersing rods 16 can disperse the floating air bubbles, making them into small air bubbles. The overall heat exchange area with the water is larger and the heat exchange effect is better. The diversion holes 19 can further squeeze and break the air bubbles. By using the protective box 13, the leeches can be prevented from getting too close to the heat source (i.e., the exhaust hole 15), and the dispersing rods 16 can be prevented from damaging the leeches. It should be noted that the power supply of the second motor 10 and the heating air pump 8 in this scheme needs to be reserved with long wires to ensure their power supply in the moving state.

[0030] In this utility model, when it is necessary to perform high-temperature treatment on the water body, the heating air pump 8 is turned on. The heating air pump 8 is composed of an air pump and a heating element (such as an electric heating wire). After starting, hot air is blown out. The hot air enters the rotating tube 11 through the rotary joint 9. Since the lower end of the rotating tube 11 is sealed and exhaust holes 15 are opened on both sides, the hot air is discharged from the exhaust holes 15 into the water of the aquaculture pond 1 to raise the water temperature.

[0031] Simultaneously, the first motor 4 is started, and the output shaft of the first motor 4 drives the reciprocating screw 3 to rotate between the inner walls of the left and right sides of the U-shaped frame 2. Because the slider 5 is threadedly connected to the reciprocating screw 3, and the upper end face of the slider 5 is slidably connected to the inner top of the U-shaped frame 2, the slider 5 moves back and forth on the reciprocating screw 3 when the reciprocating screw 3 rotates. Since the front side of the slider 5 is fixedly connected to the rear side of the moving plate 6, the reciprocating movement of the slider 5 drives the moving plate 6 to move synchronously, thereby causing the rotating tube 11 to move back and forth above the breeding tank 1, so that hot air can be discharged at different positions in the breeding tank 1, expanding the heating range.

[0032] As the rotating tube 11 moves, the second motor 10 starts. The synchronous pulley 17 on the output shaft of the second motor 10 drives the synchronous pulley 17 on the rotating tube 11 to rotate through the synchronous belt 18, thereby causing the rotating tube 11 to rotate. During the rotation of the rotating tube 11, the bubbles formed by the hot air discharged from its lower end enter the water body more evenly.

[0033] When the rotating tube 11 rotates, it drives the multiple dispersing rods 16 located inside and outside the protective box 13 to rotate. The dispersing rods 16 disperse the floating bubbles, turning large bubbles into small bubbles, increasing the heat exchange area between the bubbles and the water, and improving the heat exchange effect. At the same time, the multiple diversion holes 19 opened on the side wall of the protective box 13 can further squeeze and break the bubbles, further enhancing the heat exchange effect. In addition, the protective box 13 can prevent leeches from getting too close to the heat source (i.e., the vent 15), preventing the leeches from being damaged by excessively high water temperature, and at the same time, preventing the dispersing rods 16 from damaging the leeches during rotation.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
