Description

Technical Field

[0001] This utility model relates to the field of GPS tag technology, and in particular to a portable GPS positioning device for fish migration with self-powered kinetic energy. Background Technology

[0002] Using appropriate GPS positioning devices for fish migration, we can explore the long-distance, large-span life cycle of aquatic organisms, especially migratory fish, during their upstream migration for reproduction and survival, as well as the impact of power station operation and regulation on their migratory behavior trajectories. This will further allow us to explore measures to mitigate the impact of water conservancy project construction and power station operation and regulation on migratory fish.

[0003] Although research on fish migration tracking tags has made some progress in recent years, both domestically and internationally, the types of fish migration tracking tags are relatively limited, and they cannot be used for long-distance, large-span migration monitoring. Furthermore, there is a lack of kinetic energy devices that can provide long-term operational capabilities. In addition, the traditional method of fixing fish migration tracking tags involves implanting them into the fish's body. This method not only causes permanent physiological damage to the fish, affecting their survival, reproduction, and other life processes, but also further influences their behavior. To a certain extent, it cannot reflect the true migration trajectory of fish, and the cumulative effect increases the deviation of the studied migratory fish behavior trajectory. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a portable GPS positioning device for fish migration with self-powered kinetic energy, which solves the problems of GPS positioning devices currently attached to migratory fish causing permanent physiological damage and the inability of GPS positioning tags for migratory fish to perform long-distance, large-span long-term fish trajectory monitoring.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a portable GPS positioning device for fish migration with self-powered kinetic energy, including a head elastic ring and a tail elastic ring fitted on the surface of the fish body. The head elastic ring is close to the position of the front fin, and the tail elastic ring is close to the position of the rear fin. An elastic back strap is provided between the head elastic ring and the tail elastic ring. The elastic back strap is equipped with a GPS positioning device, a micro battery, and a micro water flow power generation device.

[0006] Preferably, the elastic shoulder strap includes an upper shoulder strap and a lower shoulder strap, wherein the upper shoulder strap and / or the lower shoulder strap is composed of two intersecting shoulder straps.

[0007] Preferably, the elastic strap is a single strap that is wrapped sequentially around the head elastic loop and the tail elastic loop, and crosses on the upper and / or lower side of the fish's body.

[0008] Preferably, the elastic shoulder strap surface is also provided with an adjustment buckle to adjust the tightness.

[0009] Preferably, the elastic straps are interlaced at their cross-positions to form a fixed knot.

[0010] Preferably, the GPS positioning device, the micro battery, and the micro water flow generator are all housed within the outer casing, which is fixed to the surface of the elastic back strap. The water turbine blades of the micro water flow generator are connected to the external water flow. The output end of the micro water flow generator is connected to the input end of the micro battery, the output end of the micro battery is connected to the input end of the GPS positioning device, and the signal transmitter of the GPS positioning device is wirelessly connected to the signal receiver of the computer processing system.

[0011] Preferably, the outer shell is also filled with a cushioning material.

[0012] The beneficial effects of this utility model are:

[0013] (1) This utility model solves the problem that GPS positioning devices currently added to migratory fish cause permanent physiological damage to them and that GPS positioning tags for migratory fish cannot perform long-distance, large-span long-term fish trajectory monitoring.

[0014] (2) Conventional fish migration GPS positioning tags are limited by the inability to study fish migration trajectories over long periods and over large spans. They can only explore fish migration behavior in a specific period of a specific watershed. Furthermore, the fixing method used is an implantation method that can cause permanent damage to fish. Therefore, conventional fish migration GPS positioning tags can only explore the migration trajectory mechanism of migratory fish with impaired physiological functions in a specific period of a specific watershed. The portable fish migration GPS positioning device with self-powered kinetic energy proposed in this utility model innovatively adopts the form of fixing fish migration tags by combining elastic straps with elastic rings at the head and tail. This avoids the possibility of causing permanent physiological damage to migratory fish and affecting their behavioral trajectory. It is a fish-friendly fish migration GPS positioning tag.

[0015] (3) The present invention arranges a micro water flow generator and uses the micro water flow generator to provide kinetic energy, which can greatly increase the working time of the GPS positioning tag for fish migration, further expand the research scope of the behavior trajectory of migratory fish, fundamentally solve the defect that GPS cannot complete the monitoring of the behavior trajectory of migratory fish over long time spans and long distances, make the monitoring of migratory fish more complete, and provide a more credible theoretical basis for exploring the mechanism of the behavior trajectory of migratory fish.

[0018] Figure 3 This is a schematic diagram of the internal structure of the outer shell. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-3 As shown, a portable GPS positioning device for fish migration with self-powered kinetic energy includes a head elastic band 1 and a tail elastic band 2 fitted onto the surface of the fish's body. The head elastic band 1 is located near the front fin 3, and the tail elastic band 2 is located near the rear fin 4. An elastic back strap 5 is provided between the head elastic band 1 and the tail elastic band 2. The elastic back strap 5 is equipped with a GPS positioning device 6, a miniature battery 7, and a miniature water flow power generation device 8.

[0021] The elastic shoulder strap 5 can be implemented in the following two ways:

[0022] Example 1: As Figure 1 and 2 As shown, the elastic shoulder strap 5 includes an upper shoulder strap 5.1 and a lower shoulder strap 5.2, wherein the upper shoulder strap 5.1 and / or the lower shoulder strap 5.2 are composed of two intersecting shoulder straps. This intersecting shoulder strap combination prevents the entire elastic shoulder strap 5 from slipping.

[0023] Example 2: The elastic harness 5 is a single strap that is sequentially wrapped around the head elastic loop 1 and the tail elastic loop 2, crossing over the upper and / or lower sides of the fish's body. This implementation method is simpler; as long as the wrapping method is correct, the installation process can be completed quickly, and the crossing method can prevent the entire elastic harness 5 from slipping.

[0024] Preferably, the elastic strap 5 is further provided with an adjustment buckle 5.3 for adjusting the tightness. The tightness of the entire elastic strap 5 can be adjusted at the beginning of installation by adjusting the buckle 5.3, and the tightness can be adjusted adaptively according to the size of the fish.

[0025] Preferably, the elastic straps 5 are interlaced at their crossing points to form a fixing knot 5.4. The fixing knot 5.4 can further enhance the stability of the entire elastic strap 5 after it is installed on the fish's body surface and prevent it from loosening.

[0026] Preferably, the GPS positioning device 6, the miniature battery 7, and the miniature water flow generator 8 are all housed within the outer casing 9, which is fixed to the surface of the elastic shoulder strap 5. The water turbine blades of the miniature water flow generator 8 are connected to the external water flow. The output end of the miniature water flow generator 8 is connected to the input end of the miniature battery 7, and the output end of the miniature battery 7 is connected to the input end of the GPS positioning device 6. The signal transmitter of the GPS positioning device 6 is wirelessly connected to the signal receiver of the computer processing system. The computer processing system can record the information fed back by the GPS positioning device 6, thereby monitoring the fish migration trajectory in real time.

[0027] Preferably, the outer casing 9 is further filled with a cushioning material 10. In this embodiment, the cushioning material 10 can be cotton, rubber, foam, or other cushioning materials, which can effectively avoid direct contact and collision between the devices and prevent damage.

[0028] The working principle of this utility model is as follows:

[0029] In this invention, by placing the head elastic band 1 close to the location of the front fin 3 and the tail elastic band 2 close to the location of the rear fin 4, the fish's own front and rear fins can be used as limiting devices to fix the positions of the head elastic band 1 and the tail elastic band 2, preventing them from moving closer together due to the tension of the elastic dorsal strap 5. Furthermore, the head elastic band 1, tail elastic band 2, and elastic dorsal strap 5 are all elastic band structures, which will not damage the fish's surface. They can also adaptively expand as the fish grows, without restricting its growth. The micro-water flow power generation device 8 generates its own electricity, which is stored in the micro-battery 7 and then powers the GPS positioning device 6, enabling it to operate normally and achieve long-term, large-span monitoring of fish migration trajectories.

[0030] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
