Description

Technical Field

[0001] This utility model relates to the field of ecological and environmental protection, specifically to an anti-electrofishing early warning device that detects electrofishing signals from multiple angles. Background Technology

[0002] Lakes and rivers are vital freshwater ecosystems, nurturing abundant fishery resources and maintaining a balance of biodiversity. However, illegal electrofishing has caused severe damage to these valuable resources and ecosystems. Because electrofishing often employs covert tactics, regulatory authorities face significant challenges in detection, evidence collection, and enforcement. To address this challenge, several anti-electrofishing early warning devices based on detecting electrofishing signals have emerged, aiming to use technological means to provide early warnings and curb illegal electrofishing. For example, Chinese utility model patent CN209803230U and Chinese invention patent CN109799383A disclose an anti-electrofishing early warning device based on Internet of Things technology. The device adopts an integrated structure design of cast iron anchor and aluminum outer casing. A current transformer is fixed in the center of the device for detection. When an electrofishing signal occurs in the water, the transformer sends an alarm command to the central control integrated IC and notifies the remote server of the electrofishing alarm at the monitoring point through a 4G module. Chinese utility model patent CN111510858A discloses a detection, early warning and positioning buoy for electrofishing devices. The device is fixed by an anchor, anchor chain and buoy structure. The copper sulfate electrode measures the electric field component in the horizontal direction and sends it to the central processing unit for processing, alarm and positioning.

[0003] However, all of the aforementioned devices share a common drawback: they only have a single, fixed electrofishing detection channel. When electrofishing signals come from different directions in the water, they are prone to missed detections, leading to the inability to issue timely warnings. This poses a significant challenge to the protection of fishery resources and the daily supervision of fish protection areas. Therefore, there is an urgent need for an anti-electrofishing warning device with multi-angle electrofishing signal detection capabilities. This would more effectively assist relevant departments in detecting and combating electrofishing activities, protecting fishery resources in lakes and rivers, safeguarding the legitimate rights and interests of fishermen, and is of great significance for the ecological protection and fishery management of lakes and rivers. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-electrofishing early warning device that detects electrofishing signals from multiple angles, 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: It includes a control box containing a main controller, a current transformer, a detection circuit board, a 5G communication module, a GPS, and a power module. An antenna is embedded in the top of the control box, surrounded by a transparent waterproof protective cover. Current probes are connected to opposite ends of the current transformer. The output interface of the current transformer is connected to a signal detection circuit. A floating platform is built into the bottom, filled with cushioning foam, and a fixing ring is attached to the bottom. The fixing ring is connected to the control box via fixing holes, which stabilize the floating platform. A telescopic rope is attached to the center below the fixing ring, and a threaded connection is used to connect it to a cast iron anchor. A truncated cone locking pin is cast at equal intervals in the middle of the cast iron anchor. A slot is opened every 60° on the circular outer wall of the control box, for a total of 6 slots. Six lead wire slots are welded in each slot, and current probes are fixed inside the slots using locking weights and sealed with sealing buckles.

[0006] Preferably, the button lock weight is made of refined metal material, and the locking position is driven by rotating the button nut to achieve the tight compression of the current probe. The sealing buckle is designed to be installed in the groove at the bottom of the lead slot for sealing treatment.

[0007] Preferably, the mid-section structure of the cast iron anchor, the frustum locking pin, is integrally cast and smelted with the cast iron anchor. The integrated design enhances the stability and durability of the structure. The frustum locking pin adopts a symmetrical structure, with the two circles on the upper and lower bottom surfaces expanding outward evenly along the central axis to form a frustum shape, making the locking pin more stable when under force.

[0008] Preferably, the control box has a slot every 60° on its circular outer wall, for a total of 6 slots. Each slot is fixed and connected to the lead wire slot by welding, for a total of 6 lead wire slots. Every 2 lead wire slots on opposite sides are grouped together, for a total of 3 groups of lead wire slots.

[0009] Preferably, the lead wire groove is equipped with a current probe, which serves as a sensor to collect the electric fish signal in the water. The current probes in the same group of lead wire grooves are connected to the input terminal of the current transformer through wires. The three groups of lead wire grooves are connected to three current transformers. Every two current probes form a linear detection channel. This device has three linear detection channels.

[0010] Preferably, the telescopic rope pulls and restrains the movement of the fixed ring structure, thereby restraining and pulling the movement of the device body. The floating platform can support the device on the water surface and, combined with the cast iron anchor, achieve fixed floating movement on the water surface, driving the three sets of detection channels to float and move, realizing multi-angle signal detection and improving the early warning effect of electrofishing signals.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device enables multi-angle detection of electrofishing signals, effectively improving the early warning effect against electrofishing. The device features carefully designed slots around the control box, with six lead-in slots securely connected to the control box using welding technology. The lead-in slots are arranged at a 60° angle. Each lead-in slot contains a built-in current probe, and the control box is equipped with three current transformers. Every two lead-in slots in opposite positions, along with one current transformer, form a linear detection channel. The device has three sets of linear detection channels. When electrofishing occurs, the current probe in the same set of detection channels collects the current signal released by the electrofishing device and transmits it to the current transformer. These three sets of detection channels can collect signals from three different angles. Thanks to the device's fixed floating structure, the detection channels can float and move freely, enabling multi-angle electrofishing signal collection. The collected signal is converted into a voltage signal by the current transformer and transmitted to the detection circuit for processing. The processed result is sent to the main controller for judgment and analysis, thus realizing the multi-angle electrofishing signal detection function and effectively improving the early warning effect against electrofishing.

[0013] (2) This device has excellent stability. The fixed floating structure of the device consists of three key components: a cast iron anchor, a telescopic rope, and a floating platform. The mid-section of the cast iron anchor is equipped with a frustum locking pin. The frustum shape makes the locking pin more stable when subjected to external forces, allowing it to be firmly fixed to the riverbed. The telescopic rope has good elasticity and is connected to the control box through a fixed ring structure. It works in conjunction with the floating platform structure below the control box to keep the device floating on the water surface and adapt to the fluctuations and changes in the water surface. When the water surface fluctuates, the cast iron anchor structure keeps the device stable and secure to the riverbed, preventing the device from shaking violently with the waves; the telescopic rope and the floating platform can buffer the impact of water surface fluctuations to a maximum extent, greatly reducing the risk of device damage.

Detailed Implementation

[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. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 An anti-electrofishing early warning device for multi-angle detection of electrofishing signals includes a control box 8. The control box 8 contains a main controller 4, a current transformer 7, a detection circuit board 3, a 5G communication module 6, a GPS module 5, and a power module 2. An antenna 1 is embedded in the top of the control box, and a transparent waterproof protective cover surrounds the antenna. The power module 2 supplies power to the devices by converting the voltage required by different components. The current transformer 7 increases the induced current by winding wires around itself. Both ends of the current transformer 7 are electrically connected to opposing current probes 14, and its output interface is electrically connected to the input port of the detection circuit board. A floating plate 9 is connected to the bottom, and a buffer bubble is filled on top of the floating plate 9. The bottom of the float is connected to a fixed ring 10. The fixed ring 10 is connected to the control box 8 through a fixed hole, which makes the float stable. The fixed ring 10 has a threaded female at the center of its lower part. The telescopic rope 11 is fitted with threaded male posts at both ends. The fixed ring 10, the cast iron anchor 12 and the telescopic rope 11 can be connected through the threaded engagement. The cast iron anchor 12 is welded with truncated cone locking pins 17 at equal intervals in the middle. Six lead wire grooves 13 are welded to the outside of the control box 8. The lead wire grooves 13 are hollow inside and are conductive to the control box. Current probes 14 are placed in the grooves. The current probes 14 and the lead wire grooves are fitted with button lock weights 15 and sealing buckles 16 for fixing and sealing.

[0021] In use, this invention is first fixed in the riverbed by a cast iron anchor, and then further secured by a frustum locking pin 17. The ends of the telescopic rope 11 are connected to the cast iron anchor and a fixing ring, respectively. The fixing ring 10 is connected to the bottom of the control box and is used to fix and stabilize the floating platform 9. A current probe 14 is placed underwater through a lead-in groove to collect the current signal released by the electrofishing device. The current signal is transmitted to the current transformer 7 through a wire in the lead-in groove 13. The current transformer converts the current signal into a voltage signal and transmits it to the detection circuit board 3. The detection circuit board 3 processes and analyzes the voltage signal and transmits the result to the main controller 4 for judgment via a transmission line. When the judgment result of the main controller 4 is true, the main controller 4 will automatically call the GPS module 5 to locate the device in real time. At the same time, the location information and warning information are sent to the remote client and mobile client via the antenna 1 through the 5G communication module 6. The device displays and records location information and movement trajectory in real time on both remote and mobile clients, allowing fishery law enforcement personnel to monitor the location of electrofishing devices and provide evidence to support law enforcement actions.

[0022] Working Principle: The device described in this invention can be used individually or in combination, with the number depending on the area of ​​the water to be monitored. When the device is deployed in the water, the cast iron anchor 12 is driven into the riverbed for fixation. The device is then further secured by the frustum locking pin 17 embedded in the riverbed, achieving a stable effect. The length of the telescopic rope 11 is freely determined by the water depth and the historical highest water level. The telescopic rope 11 connects the fixing ring 10 and the cast iron anchor 12. The fixing ring 10 fixes the floating platform 9 to the bottom of the control box 8, preventing the floating platform 9 from drifting freely and causing uneven force, which could lead to the device tipping over. The space between the floating platform 9 and the control box 8 is filled with buffer foam to buffer the disturbance of water waves. When the device is lifted onto the horizontal surface by the floating platform 9, the telescopic rope 11 is in a stretched state, restraining the movement of the fixing ring 10, which in turn restrains the movement of the control box 8. When the electrofishing device detects a positive signal, it automatically uses the GPS module to pinpoint its location. The location information and warning information are then transmitted to remote and mobile clients via 5G communication and an antenna, allowing fishery law enforcement personnel to monitor the device's location in real time.
