Description

Technical Field

[0001] The invention relates to the technical field of crayfish catching, and in particular to a harvesting and catching device used for crayfish breeding. Background Art

[0003] It should be noted that the conventional harvesting and capturing process first requires a lot of manpower and working hours, and the cages must be released and checked regularly, which cannot fully meet the efficiency of fishing operations in artificial breeding. If no crayfish are caught in the cage or only a small number of crayfish are caught, it is necessary to re-put bait for re-release, and the harvesting efficiency is not high. It should also be noted that when there are relatively many crayfish in the cage, due to the aggressiveness of the crayfish, the crayfish will suffer varying degrees of damage, such as the lack of chelicerae. This application proposes a solution to this problem. Summary of the invention

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: For the artificially cultivated crayfish fishing operation, the conventional fishing operation method is difficult to meet the high efficiency of artificial breeding, and in the fishing operation, the large-scale fishing method will cause different degrees of damage to the crayfish, and will also invest a lot of manpower and working hours. The following technical solution is proposed:

[0028] Reference Figures 1 to 6 In this embodiment, a harvesting and capturing device for crayfish breeding is used in an artificial crayfish breeding pond, and includes a shrimp cage body 3, a base pedestal 1 and a bearing column 5. The base pedestal 1 is arranged at the bottom of the artificial crayfish breeding pond, and the bearing column 5 is installed at the center point of the base pedestal 1 in a vertical direction. The shrimp cage body 3 is arranged on the base pedestal 1 through the bearing column 5, and the top of the bearing column 5 is higher than the surface of the artificial crayfish breeding pond.

[0029] An inflatable buoy 4 and a counterweight 2 are provided on the shrimp cage body 3 , a pressure-bearing sac 7 is provided on the load-bearing column 5 corresponding to the lower side of the shrimp cage body 3 , and a pressure detection component 6 corresponding to the pressure-bearing sac 7 is provided in the base 1 .

[0030] Basic principle: For the process of catching crayfish, the simplest and most efficient method is to use a shrimp cage, based on the shrimp cage body 3 of the present invention, by placing heavy-tasting bait inside it to attract crayfish to enter the shrimp cage body 3. Its essence is to regularly put the shrimp cage body 3 into the bottom of the artificial crayfish breeding pond, and recycle the shrimp cage body 3 on time, and further collect the crayfish captured inside the shrimp cage body 3;

[0031] The difference between this embodiment and the conventional fishing method is that: first, a number of base platforms 1 and load-bearing columns 3 are built according to the artificial crayfish breeding pond, and the placement position of the shrimp cage body 3 is limited by the load-bearing columns 5. When the shrimp cage body 3 is placed, the center point position of the shrimp cage body 3 keeps sliding with the load-bearing columns 5. The guiding effect of the load-bearing columns 5 ensures that the shrimp cage body 3 will slowly sink to the designated position and trap.

[0032] Embodiment 2: Based on the basic principle of Embodiment 1, the following supplementary explanation is made:

[0033] The pressure detection component 6 includes a pressure detection structure and a wireless transmission component. The conducting end of the pressure detection structure is connected to the inside of the pressurized balloon 7. A water injection channel 8 is opened inside the load-bearing column 5. The lower end of the water injection channel 8 extends to the position of the shrimp cage body 3. The load-bearing column 5 is provided with a water spray port corresponding to the water injection channel 8 on the outer wall position of the shrimp cage body 3. The counterweight block 2 is installed on the lower side of the shrimp cage body 3, and the inflatable float 4 is installed on the lower side of the outer wall position of the shrimp cage body 3. The outside of the artificial crayfish breeding pond is provided with a water injection structure and an air replenishing structure corresponding to the water injection channel 8 and the inflatable float 4.

[0034] The process of use includes quantitative floating process and directional support process, including the following contents:

[0035] Quantitative floating process: through the pressure difference formed by the gravity of the counterweight block 2 and the shrimp cage body 3 and the buoyancy of the inflatable float 4, the shrimp cage body 3 is located on the base 1, and the air pressure detection component 6 generates an action command for the inflatable float 4, driving the shrimp cage body 3 to float upward along the direction of the load-bearing column 5;

[0036] Directional support process: During the quantitative floating process, the energized winding coil 9 is energized, and the energized winding coil 9 and the permanent magnetic ring block 10 generate a repulsive force, which drives the permanent magnetic ring block 10 to move upward and drives the support frame rod 11 to expand outward, and the shrimp cage body 3 continues to move upward through the support frame rod 11 and the permanent magnetic ring block 10.

[0037] Solution description: As shown in the first embodiment, the conventional shrimp cage needs to regularly check the amount of crayfish caught in the cage during the capture process. The relevant structure of this embodiment is explained as follows:

[0038] S1: First, the shrimp cage body 3 can sink to the bottom of the artificial crayfish breeding pond under its own weight, and a counterweight block 2 is added to the lower side of the shrimp cage body 3 to increase the weight of the shrimp cage body 3. In addition, an inflatable float 4 is further added to increase the buoyancy of the shrimp cage body 3. However, after the shrimp cage body 3 sinks to the bottom of the artificial crayfish breeding pond, the inflatable float 4 is not inflated to obtain buoyancy, so that the shrimp cage body 3 will pressurize the pressurized balloon 7, causing the pressurized balloon 7 to be compressed and deformed, and the pressure detection structure in the pressure detection component 6 monitors the pressure change inside the pressurized balloon 7 in real time;

[0039] S2: Further explanation of S1, when catching crayfish with bait, the pressure of the shrimp cage body 3 on the pressure balloon 7 gradually increases, so that the pressure value of the pressure balloon 7 gradually increases. A brief explanation of this is: in the initial state, the pressure change of the pressure balloon 7 is equal to the weight of the shrimp cage body 3, the weight of the counterweight 2 and the weight of the captured crayfish, and the weight of the shrimp cage body 3 and the weight of the counterweight 2 are constant values, so that the pressure change of the pressure balloon 7 can directly feedback the weight of the crayfish captured inside the shrimp cage body 3. This part is mainly To provide feedback on the capture rate of crayfish, the staff does not need to check regularly, and it also avoids the crayfish "fighting" when the capture rate of crayfish is high, resulting in the loss of chelipeds that affects the appearance. The maximum upper limit of the pressure change of the pressurized balloon 7 is set according to the actual parameters. When the pressure change of the pressurized balloon 7 reaches the maximum upper limit, the inflatable float 4 is inflated through the air replenishing structure, so that the shrimp cage body 3 generates an upward buoyancy and drives the shrimp cage body 3 to float automatically. This method reduces the operating steps of the staff and reduces physical exertion. The overall structure has the characteristic of intelligent control.

[0040] S3: It needs to be explained separately that, refer to Figure 3 and Figure 5 After the shrimp cage body 3 is put into the bottom of the artificial crayfish breeding pond, the water injection channel 8 at the top position of the load-bearing column 5 can be continuously injected with water through the water injection structure. This method forms a water inlet position in the internal position of the shrimp cage body 3. Specifically, because crayfish have a strong tendency to tend to water, they especially like new water and running water and often swim upstream. In the breeding pond, they often gather around the water inlet because there is fresh water flow there. On rainy days, crayfish will climb up the shore against the flow for a short stay or escape. When the environment in the water is not suitable for them, they will also choose to climb up the shore to find a better habitat. For this, the water inlet position is simulated by actively injecting water, which prompts crayfish to concentrate at the position of the shrimp cage body 3, and uses heavy-tasting bait to increase the capture rate of crayfish.

[0041] Embodiment 3: This embodiment is a supplementary explanation of Embodiment 2:

[0042] An energized winding coil 9 is installed in the internal position of the upper end of the load-bearing column 5, and a permanent magnetic ring block 10 is slidably installed in the vertical direction on the upper end outer wall position of the load-bearing column 5 corresponding to the energized winding coil 9, and a plurality of support frame rods 11 are rotatably installed on the permanent magnetic ring block 10 along a circular array. An arc angle corresponding to the direction of the load-bearing column 5 is opened on the upper end position of the support frame rod 11, and a guide ring block 13 is slidably installed in the upper end outer wall position of the load-bearing column 5 corresponding to the permanent magnetic ring block 10. An inner guide frame rod 12 corresponding to the support frame rod 11 is rotatably installed on the guide ring block 13 along a circular array, and one end of the inner guide frame rod 12 is rotatably connected to the support frame rod 11.

[0043] Solution description: As supplemented by Example 2, first of all, the water level of the artificial breeding pond of crayfish is not high, and the buoyancy decreases with the water level. For this, the present invention first limits the setting position of the inflatable float 4, specifically, it is set at the lower side of the shrimp cage body 3. However, when the shrimp cage body 3 is driven to float by the inflatable float 4, it cannot be completely guaranteed that the shrimp cage body 3 is exposed above the water surface. For this, a support frame rod 11 is added. In the initial state, the energized winding coil 9 generates suction with the permanent magnetic ring block 10 in the energized state, thereby ensuring that the permanent magnetic ring block 10 is always located at the lowermost position. In this process, under the joint action of the inner guide frame rod 12 and the guide ring block 13, each support frame rod 11 is completely retracted to ensure that the outer curved surface of the support frame rod 11 matches the outer curved surface of the load-bearing column 5, avoiding interference with the floating action of the shrimp cage body 3.

[0044] The key point is: after the shrimp cage body 3 floats to a certain extent, it is difficult to continue to float and will not float to the surface. For this reason, it is necessary to generate repulsive force with the permanent magnetic ring block 10 by the energized winding coil 9 in the energized state, thereby driving the permanent magnetic ring block 10 to move upward. Because of the restriction of the support frame rod 11 and the inner guide frame rod 12, the support frame rod 11 expands outward at its lower side position, and in order to avoid interfering with the outward expansion action of the support frame rod 11, it is necessary to further limit the upper end position of the support frame rod 11 to open an arc angle corresponding to the direction of the load-bearing column 5, but it is also necessary to explain The point is that when the support frame rod 11 expands outward, it will also be restricted by the inner guide frame rod 12, so that the support frame rod 11 can only expand outward to a certain extent and is difficult to continue to expand outward, but the permanent magnetic ring block 10 continues to be repelled by the energized winding coil 9, thereby driving the permanent magnetic ring block 10 and the guide ring block 13 to continue to move upward. Specifically, the support frame rod 11 provides a supporting force to the lower side position of the shrimp cage body 3, and uses the repulsive force of the energized winding coil 9 as a driving force to drive the shrimp cage body 3 to continue to move upward, ensuring that the shrimp cage body 3 floats to the surface and the staff can collect the crayfish inside the shrimp cage body 3.

[0045] In summary: improvements are made to the artificially cultivated crayfish fishing operations, based on conventional bait trapping methods and the living habits of crayfish, and the shrimp cage body is used as the basic structure for catching crayfish. The key lies in the weight ratio between the inflatable float and the counterweight block, and optimizing the downward pressure of the pressurized balloon on the shrimp cage body, so as to judge the crayfish catch in the shrimp cage body. There is no need to invest a lot of manpower for regular observation and collection, and to avoid damage caused by a large number of lobsters caught in the cage. In combination with the above content, it is also necessary to explain: the buoyancy of the inflatable float is further utilized to drive the shrimp cage body to move automatically upward, and the shrimp cage body is initially supported and secondary assisted in movement by the support frame rod and the inner guide frame rod. The purpose is to reduce the physical exertion of personnel by simplifying the work intensity.
