Description

Technical Field

[0001] The present invention relates to the field of line leakage detection, and in particular to a line leakage detection device and a detection method. Background Art

[0002] As power grid coverage expands, the probability of leakage increases due to aging, insulation damage, and environmental corrosion. This can not only cause equipment failure and power loss, but can also lead to safety incidents such as electric shock and fire. Traditional leakage detection relies on manual inspections or fixed-point monitoring, which suffers from response lag, limited coverage, and poor adaptability to complex environments (such as high altitude and outdoor environments). This makes it difficult to meet real-time and accurate safety protection requirements, necessitating the urgent need for specialized devices that can automatically monitor and provide rapid warnings. However, most line leakage detection devices typically rely solely on solar power and lack protection for energy storage batteries, making them vulnerable to voltage fluctuations. Overcharging often leads to sulfation and bulging of battery plates, significantly shortening their lifespan or even rendering them useless. Furthermore, they are unable to intercept sudden high currents during power generation, which can easily cause battery plate deformation and internal short circuits. Continuous charging in high-temperature environments can lead to electrolyte evaporation, leakage, and even fire. Furthermore, operating the devices live when a line leakage is detected can increase safety risks. Summary of the Invention

The tightening toothed belt ensures stable and non-slip transmission, thereby improving the efficiency of wind power generation, especially suitable for low wind speed environments in the wild.

[0013] A line leakage detection device and detection method, comprising the following steps: S1: Insert the line to be tested from the device entrance so that it fits into the limit groove of the rotating roller in the moving component. The return spring applies initial pressure to make the line and the rotating roller fit together. Then, the main control launch board starts the synchronous motors in the four connecting seats on one side, driving the rotating rollers to rotate in the same direction. The device moves along the line. The return spring continues to apply pressure to ensure that the limit groove and the line fit tightly and adapt to fluctuations in wire diameter. S2: When the device moves, the motor drives the bidirectional screw to rotate, causing the clamps to move toward each other. The telescopic rod is extended so that the detection probe contacts the line surface. The current signal is collected in real time and transmitted to the current detection module. After processing, it is uploaded to the main control transmitter board and the remote terminal. S3: For power supply, the solar panels convert light energy into electrical energy and store it in the storage panels. At the same time, the wind energy at high altitude drives the main shaft and the rotating large gear through the wind-collecting rotating parts, and then drives the driven small gear through the fastened toothed belt. After the large gear and the connecting small gear stabilize the speed, it drives the small generator to generate electricity, which is then replenished to the storage panels. The dual energy sources work together to maintain battery life. S4: Overcharge protection: The voltage sensor on the overcharge protection board monitors the voltage of the storage battery panel in real time. When the voltage is detected to be ≥14.5V (this threshold is the critical value for a fully charged battery; exceeding it can easily lead to plate sulfation and battery bulging), the signal is transmitted to the MCU. The MCU immediately controls the relay inside the circuit breaker to disconnect, cutting off the charging circuit of the solar panel and wind power generation to the battery, avoiding overcharge damage. Overcurrent protection: The Hall current sensor of the overcurrent protection board monitors the charging current. When the current is greater than 12A (set at 1.2 times the rated charging current for a battery capacity of 100Ah, exceeding which will increase the internal heating of the battery and shorten its life), the signal is judged by the comparator and the electronic fuse is triggered to melt, cutting off the charging circuit to prevent deformation of the battery plates caused by high current. Over-temperature protection: The NTC thermistor and temperature detection chip on the over-temperature protection board monitor the temperature of the battery and charging circuit. When the temperature is greater than 55°C (the optimal operating temperature of a lead-acid battery is 25-40°C; if it exceeds 55°C, electrolyte evaporation accelerates and battery capacity drops sharply), the fixed circuit breaker is activated to cut off charging to prevent high temperature from causing battery leakage or fire. S5: If the detection probe and current detection module confirm that the line is leaking, the main control transmitter board will preferentially cut off the battery charging through the above protection mechanism (to prevent the device from running with power on and increasing the risk), and at the same time send a leakage alarm to the remote terminal to ensure timely response to the line fault under the premise of ensuring battery safety.

[0014] The present invention provides a circuit leakage detection device and detection method, which have the following beneficial effects: The present invention provides a circuit leakage detection device and detection method. The voltage sensor of the overcharge protection board is linked with the MCU. When the storage battery plate voltage is ≥14.5V, charging is cut off, matching the battery full charge threshold, avoiding plate sulfation, bulging and other problems caused by overcharging, and extending the battery life. The Hall current sensor of the overcurrent protection board cooperates with the electronic fuse to quickly blow when the charging current is greater than 12A, which can effectively prevent the impact of large current on the battery plate, prevent plate deformation or internal short circuit, and ensure the safety of the battery structure. The NTC of the overtemperature protection board The thermistor works in conjunction with a fixed circuit breaker to cut off charging when the temperature is >55°C, adapting to the optimal operating temperature range of the battery, preventing high temperature from causing electrolyte evaporation, leakage, and even fire, thereby improving the safety of device operation. At the same time, this mechanism targets the volatility of solar and wind power generation, ensuring a stable and controllable charging process through hierarchical protection, reducing damage to the battery caused by energy fluctuations. The logic of prioritizing charging when leakage occurs can avoid the device from operating with power and increasing safety risks. Combined with remote alarms, it can achieve rapid response to faults, taking into account the reliability of battery protection and line detection, allowing the device to have long-term endurance in complex environments such as high-altitude lines while ensuring the safety of itself and the lines.

10. A detection method for a line leakage detection device, characterized in that: The following steps are included: S1: The line to be tested is passed through the entrance of the device so that it fits into the limiting groove (15) of the rotating roller (501) in the moving component. The return spring (506) initially applies pressure to allow the line to initially fit into the rotating roller. Then, the main control transmitting plate (4) starts the synchronous motor (502) in the four connecting seats (503) on one side, driving the rotating roller (501) to rotate in the same direction. The device moves along the line. The return spring (506) continuously applies pressure to ensure that the limiting groove (15) fits tightly into the line to adapt to the fluctuation of the line diameter. S2: When the device moves, the motor (707) is connected to drive the bidirectional screw (703) to rotate, driving the clamping plates (704) to move towards each other, and the telescopic rod (705) is connected to extend so that the detection probe (706) contacts the surface of the line, and the current signal is collected in real time and transmitted to the current detection module (702), and uploaded to the main control transmission board (4) and the remote terminal after processing; S3: In terms of power supply, the solar panel (16) converts light energy into electrical energy and stores it in the storage battery panel (12); at the same time, the wind energy at high altitude drives the main shaft (301) and the rotating large gear (302) to rotate through the wind collecting rotating member (8), and drives the driven small gear (304) through the fastening toothed belt (305), and then drives the small generator (9) to generate electricity after the large gear (306) and the connecting small gear (307) stabilize the speed, and then replenish the storage battery panel (12), so that the dual energy sources work together to sustain the battery life; S4: Overcharge protection: The voltage sensor (612) of the overcharge protection board (601) monitors the voltage of the storage battery panel (12) in real time. When the voltage is detected to be ≥14.5V, the signal is transmitted to the MCU (607). The MCU (607) immediately controls the relay in the connection breaker (604) to disconnect, cutting off the charging circuit of the solar panel (16) and wind power generation to the battery, thereby avoiding overcharge damage. Overcurrent protection: The Hall current sensor (611) of the overcurrent protection board (602) monitors the charging current. When the current is greater than 12A, the signal is judged by the comparator (608) and the electronic fuse (605) is triggered to melt, cutting off the charging circuit to prevent the large current from causing deformation of the battery plate. Over-temperature protection: The NTC thermistor (610) and the temperature detection chip (609) of the over-temperature protection board (603) monitor the temperature of the battery and the charging circuit. When the temperature is greater than 55°C, the fixed circuit breaker (606) is activated to cut off charging to prevent high temperature from causing battery leakage or fire. S5: If the detection probe (706) and the current detection module (702) confirm that the line is leaking, the main control transmitting board (4) preferentially cuts off the battery charging through the above protection mechanism, and simultaneously sends a leakage alarm to the remote terminal, ensuring timely response to the line fault under the premise of ensuring battery safety.
