Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture technology, specifically to a T-shaped marking device. Background Technology
[0002] Fish T-tags are suitable for scenarios such as stock enhancement and release, and scientific research tracking. The tip of the common hang tag-style fish T-tag has a "T" shaped structure and is usually made of PP or nylon, which has flexibility and impact resistance. During the implantation of the tag, a special syringe vertically inserts a gel needle into the muscle layer of the fish's body. The horizontal portion naturally unfolds after the gel needle enters the fish's body, forming a horizontal hook. Specifically, when the gel needle is fully inserted into the fish's body and the syringe needle is withdrawn, the horizontal portion automatically unfolds into a "T" shape within the fish's muscle tissue due to the elastic material, interlocking with the muscle or connective tissue. At this time, the tag tube at the other end of the gel needle remains exposed. The tag tube has a printed layer on it, which can be printed with information such as numbers and contact information for long-term identification. However, this type of tag-like T-shaped fish tag is prone to falling off. Other traditional tagging methods include fin clipping, electronic tags, and fluorescent tags. Fin clipping causes significant damage to the fish, electronic tags are expensive and require specialized equipment for identification, and existing fluorescent tags are not suitable for identifying fish with dark skin due to their weak fluorescence intensity. Therefore, a new type of T-shaped tagging device is urgently needed to solve the above problems. Utility Model Content
[0003] In view of this, a T-type tagging device is provided that causes little damage to the fish, is not easy to detach from the tag, can be fixed for a long time, and is low cost.
[0004] A T-shaped marking device for marking a fish's dorsal fin includes a glue needle body, a transverse glue needle head connected to one end of the glue needle body, and a digital encoding part connected to the other end of the glue needle body. It also includes an anti-detachment component fitted onto the glue needle body. The anti-detachment component includes a front anti-detachment septum and a rear anti-detachment septum. The front anti-detachment septum is close to the transverse glue needle head, and the rear anti-detachment septum is close to the digital encoding part. The glue needle body is used to pass through the dorsal fin and position the transverse glue needle head on one side of the dorsal fin. The front anti-detachment septum and the digital encoding part are located on the other side of the dorsal fin.
[0005] Furthermore, the front anti-detachment partition and the rear anti-detachment partition are respectively annular, and the inner diameter of the front anti-detachment partition is smaller than the outer diameter of the rear anti-detachment partition, so as to prevent the front anti-detachment partition from passing through the rear anti-detachment partition.
[0006] Furthermore, the digital encoding part is cylindrical, and the inner diameter of the rear anti-detachment partition is smaller than the diameter of the digital encoding part, so as to prevent the rear anti-detachment partition from passing through the digital encoding part and falling off.
[0007] Furthermore, the anti-detachment component includes 2 to 5 anti-detachment partitions, among which the front anti-detachment partition is closest to the dorsal fin and the rear anti-detachment partition is closest to the digital encoding part.
[0008] Furthermore, the elastic modulus of the 2 to 5 anti-detachment spacers gradually increases from the front anti-detachment spacer towards the rear anti-detachment spacer, or at least the elastic modulus of the front anti-detachment spacer is less than that of the rear anti-detachment spacer.
[0009] Furthermore, the 2 to 5 anti-detachment spacers are arranged along the axial direction of the glue needle body.
[0010] Furthermore, the anti-detachment component is an elastic silicone body.
[0011] Furthermore, one end of the glue needle body is fixedly connected to one end of the digital encoding part.
[0012] Furthermore, the head of the transverse glue needle is perpendicularly connected to the body of the glue needle to form a T-shaped structure.
[0013] Compared with the prior art, the present invention has at least the following beneficial effects:
[0014] First, the body of the T-shaped marking device passes through the dorsal fin of the fish, and the head of the horizontally lateral marking device and the digital coding part are located on both sides of the dorsal fin. The T-shaped head of the marking device is exposed outside the fish's body, rather than being inserted into the fish's body to form a hook in the fish's muscles. It is an external T-shaped marking device with a small incision and minimal damage to the fish.
[0015] Secondly, this T-shaped marking device is equipped with a front anti-detachment septum and a rear anti-detachment septum, both of which are made of elastic silicone. When subjected to external forces from water flow or fish activity, the front and rear anti-detachment septums prevent the glue needle from detaching from the fish. Specifically, the front anti-detachment septum acts as a buffer, while the rear anti-detachment septum acts as an anti-detachment septum, thus making this T-shaped marking device less prone to detachment and able to remain in place for a long time. This anti-detachment component has a simple structure, low production cost, and good anti-detachment effect. Attached Figure Description

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 This illustration shows a T-shaped marking device provided by an embodiment of the present invention, used for marking the dorsal fin of a fish. It includes a glue needle body 1, a transverse glue needle head 2 connected to one end of the glue needle body 1, and a digital encoding part 3 connected to the other end of the glue needle body 1. It also includes an anti-detachment component, which is fitted onto the glue needle body 1. The anti-detachment component includes a front anti-detachment partition 4 and a rear anti-detachment partition 5. The front anti-detachment partition 4 is close to the transverse glue needle head 2, and the rear anti-detachment partition 5 is close to the digital encoding part 3. The glue needle body 1 is used to pass through the dorsal fin and position the transverse glue needle head 2 on one side of the dorsal fin, while the front anti-detachment partition 4 and the digital encoding part 3 are on the other side of the dorsal fin.
[0021] Specifically, the front anti-detachment partition 4 and the rear anti-detachment partition 5 are respectively annular, and the inner diameter of the front anti-detachment partition 4 is smaller than the outer diameter of the rear anti-detachment partition 5, so as to prevent the front anti-detachment partition 4 from passing through the rear anti-detachment partition 5.
[0022] More specifically, the digital encoding part 3 is cylindrical, and the inner diameter of the rear anti-detachment partition 5 is smaller than the diameter of the digital encoding part 3, so as to prevent the rear anti-detachment partition 5 from passing through the digital encoding part 3 and falling off.
[0023] In some specific embodiments, the inner diameter of the rear anti-detachment septum 5 cannot be greater than the diameter of the digital coding section 3, and the smaller the inner diameter, the better the anti-detachment effect. However, it should be ensured that the rear anti-detachment septum 5 after maximum elastic deformation can pass through the digital coding section 3 from the rear and enter the glue needle body 1. The inner diameter of the front anti-detachment septum 4 is slightly larger than the inner diameter of the rear anti-detachment septum 5, but cannot be greater than the outer diameter of the rear anti-detachment septum 5. Otherwise, the front anti-detachment septum 4 will pass through the rear anti-detachment septum 5 and lose its buffering effect. In addition, the inner diameter of the front anti-detachment septum 4 cannot be greater than the diameter of the digital coding section 3. Otherwise, the front anti-detachment septum 4 will pass through the rear anti-detachment septum 5 and the digital coding section 3 and detach.
[0024] In some specific embodiments, when the tagged shark swims or is scratched by the fishing net, the T-shaped tagging device may fall off due to external force. The side closer to the T-shaped head of the glue needle is called the "front" and the side farther away from the T-shaped head of the glue needle is called the "rear". The transverse glue needle head 2 of this device prevents the tag from falling off from the front, while the inner diameter of the rear anti-detachment partition 5 is smaller than the diameter of the digital encoding part 3, which prevents the tag from falling off from the rear. In the process of preventing the tag from falling off from the rear, the front anti-detachment partition 4 plays a certain buffering role.
[0025] Specifically, the anti-slip component includes 2 to 5 anti-slip partitions. Among the 2 to 5 anti-slip partitions, the front anti-slip partition 4 is closest to the dorsal fin, the rear anti-slip partition 5 is closest to the digital encoding part, and the rest are middle anti-slip partitions.
[0026] In some specific embodiments, the number of anti-detachment septa is preferably 2 to 5. According to experimental studies, the detachment rate of traditional hanging T-shaped tags in the breeding of striped bamboo sharks within one month is as high as 50%, and the fin tearing caused by detachment is as high as 30%. However, the T-shaped tag device improved by this patent uses two anti-detachment septa, and the detachment rate is zero in the same period, with no fin tearing. The anti-detachment effect of two anti-detachment septa is sufficient. Appropriately adding a few more anti-detachment septa can further ensure the anti-detachment effect, but it should not exceed 5, because the heavier the T-shaped tag device hanging on one side of the fin, the easier it is to become unbalanced and increase the risk of tag detachment. Moreover, excessive weight is not conducive to the fish's flexible swimming.
[0027] More specifically, the elastic modulus of the 2 to 5 anti-detachment septa gradually increases from the front anti-detachment septa 4 towards the rear anti-detachment septa 5, or at least the elastic modulus of the front anti-detachment septa 4 is smaller than that of the rear anti-detachment septa 5. Since the front anti-detachment septa 4 is in contact with the dorsal fin, the smaller the elastic modulus of the front anti-detachment septa 4, the less it resists elastic deformation. Therefore, the front anti-detachment septa 4 is prone to elastic deformation, which is equivalent to the dorsal fin making flexible contact with the front anti-detachment septa 4, which is beneficial to protect the dorsal fin. The compressive force of the dorsal fin on the front anti-detachment septa 4 can be elastically buffered by the front anti-detachment septa 4. Then, the front anti-detachment septa 4 compresses the rear anti-detachment septa 5. The rear anti-detachment septa 5 has a large elastic modulus and a large resistance to elastic deformation. In addition, the inner diameter of the rear anti-detachment septa 5 is smaller than the diameter of the digital coding part 3, which prevents the mark from falling off. Therefore, the rear anti-detachment septa 5 plays an anti-detachment role.
[0028] More specifically, the 2 to 5 anti-detachment septa are arranged along the axial direction of the glue needle body 1. In some specific embodiments, the inner diameter of the anti-detachment septa closer to the dorsal fin is smaller than the outer diameter of the anti-detachment septa closer to the numerical encoding part in two adjacent anti-detachment septa to avoid the anti-detachment septa closer to the dorsal fin passing through the anti-detachment septa closer to the numerical encoding part.
[0029] Specifically, the anti-detachment component is an elastic silicone body.
[0030] Specifically, one end of the glue needle body 1 is fixedly connected to one end of the digital encoding part 3.
[0031] Specifically, the transverse glue needle head 2 is perpendicularly connected to the glue needle body 1 to form a T-shaped structure.
[0032] In summary, the needle body 1 of this T-shaped marking device passes through the dorsal fin of the fish, with the transverse needle head 2 and digital coding part 3 located on both sides of the dorsal fin. The T-shaped head of the needle is exposed outside the fish's body, rather than being inserted into the fish's body to form a hook within the fish's muscles. This is an external T-shaped marking device with a small incision and minimal damage to the fish. Furthermore, this T-shaped marking device is equipped with a front anti-detachment septum 4 and a rear anti-detachment septum 5, which are made of elastic silicone. When subjected to external forces from water flow or fish activity, the front and rear anti-detachment septums 4 and 5 prevent the needle body 1 from detaching from the fish's body. Specifically, the front anti-detachment septum 4 acts as a buffer, while the rear anti-detachment septum 5 acts as an anti-detachment device, thus making this T-shaped marking device less prone to detachment and able to remain in place for a long time. This anti-detachment component has a simple structure, low production cost, and good anti-detachment effect.
[0033] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
