与现有技术相比,本发明的有益效果是:Compared with the prior art, the present invention has the following beneficial effects:

1、本发明通过两个电动伸缩杆推动两个C形金属片相互贴合并包围在电路电线外侧,电路电线内部存在电流会在两个C形金属片上产生涡流现象,使得两个C形金属片上产生涡流电流,涡流电流会顺着检测电流导线传递至电动伸缩杆内部,并通过连接导线传递至保护电阻和电流传感器,电流传感器感知电流后会将信号反馈至处理芯片,处理芯片在接收信号后会将信号发送至信号发送器和定位芯片,信号发送器将电流传感器接收电流的信号反馈至电路控制中心,而定位芯片会将此时装置的位置传递至电路控制中心,进行实时检测信息反馈,保证检测数据的时效性,随后推动装置在电路电线外侧移动,直至两个C形金属片移动到故障位置,电路电线中的电流消失,使得两个C形金属片上的涡流电流消失,电流传感器无法感知电流,信号发送器、定位芯片会将电流消失信号和此处位置信号反馈至电路控制中心,可以快速定位电路电线故障点位、提高检测效率;1. The present invention uses two electric telescopic rods to push two C-shaped metal sheets to fit each other and surround the outside of the circuit wire. The current inside the circuit wire will generate eddy current on the two C-shaped metal sheets, so that eddy current is generated on the two C-shaped metal sheets. The eddy current will be transmitted to the inside of the electric telescopic rod along the detection current wire, and transmitted to the protection resistor and the current sensor through the connecting wire. After the current sensor senses the current, it will feed back the signal to the processing chip. After receiving the signal, the processing chip will send the signal to the signal transmitter and the positioning chip. The signal transmitter feeds back the signal of the current sensor receiving the current to the circuit control center, and the positioning chip will transmit the position of the device at this time to the circuit control center, and perform real-time detection information feedback to ensure the timeliness of the detection data. Then, the device is pushed to move outside the circuit wire until the two C-shaped metal sheets move to the fault position, the current in the circuit wire disappears, and the eddy current on the two C-shaped metal sheets disappears. The current sensor cannot sense the current, and the signal transmitter and the positioning chip will feed back the current disappearance signal and the position signal here to the circuit control center, which can quickly locate the fault point of the circuit wire and improve the detection efficiency.

2、本发明在装置到达电路电线故障位置时,定位芯片将此处位置信号进行反馈并被电路控制中心记录,随后可以让装置继续在电路电线上进行移动,直至两个C形金属片上涡流电流再次产生,并通过检测电流导线将涡流电流传递至保护电阻和电流传感器,使得电流传感器再次感知电流并将信号反馈至处理芯片,处理芯片通过信号发送器和定位芯片将电流再次产生信号和此处位置信号向电路控制中心反馈,通过两次位置信号之间的距离变化,可以直接确定故障的电路电线的长度,无需人工确定故障线路长度,缩短排查时间、给工作人员更换故障线路提供帮助;2. When the device of the present invention reaches the fault position of the circuit wire, the positioning chip feeds back the position signal here and is recorded by the circuit control center. Then the device can continue to move on the circuit wire until the eddy current is generated again on the two C-shaped metal sheets, and the eddy current is transmitted to the protection resistor and the current sensor through the detection current wire, so that the current sensor senses the current again and feeds back the signal to the processing chip. The processing chip feeds back the current generated signal and the position signal here to the circuit control center through the signal transmitter and the positioning chip. The length of the faulty circuit wire can be directly determined by the distance change between the two position signals, without manually determining the length of the faulty line, thereby shortening the troubleshooting time and providing assistance to the staff in replacing the faulty line.

3、本发明通过将两个分离片相互挤压靠近,此时分离片会对分离导向块挤压,使得分离导向块推动固定杆的端部向外弯曲展开,此时两个连接板之间的弹性连接绳会进行弹性伸展,且两个插接块之间间距增加,直至两个插接块之间的距离大于固定连接块的宽度,随后工作人员可以将连接板安装在固定连接块的侧面并松开卡接槽,这时两个连接板之间的弹性连接绳弹性复原拉动两个连接板复原,此时插接块会插接在卡接槽中且两个分离片会从分离滑槽中被分离导向块挤出,可以将连接板与固定连接块进行连接,使得两个移动座在固定杆、连接板和固定连接块的连接下保持稳定,不会围绕电路电线出现偏转,且只需再次将两个分离片挤压使得两个分离片相互靠近,可以将连接板的端部与固定连接块分离,便于装置进行拆卸、回收。3. The present invention squeezes the two separation sheets together and brings them close to each other. At this time, the separation sheets will squeeze the separation guide block, so that the separation guide block pushes the end of the fixed rod to bend and expand outward. At this time, the elastic connecting rope between the two connecting plates will elastically stretch, and the spacing between the two plug-in blocks will increase until the distance between the two plug-in blocks is greater than the width of the fixed connecting block. Then the staff can install the connecting plate on the side of the fixed connecting block and release the clamping groove. At this time, the elastic connecting rope between the two connecting plates elastically recovers and pulls the two connecting plates to recover. At this time, the plug-in block will be plugged into the clamping groove and the two separation sheets will be squeezed out of the separation slide groove by the separation guide block, so that the connecting plate can be connected to the fixed connecting block, so that the two movable seats remain stable under the connection of the fixed rod, the connecting plate and the fixed connecting block, and will not deflect around the circuit wires. And only by squeezing the two separation sheets again to make the two separation sheets close to each other, the end of the connecting plate can be separated from the fixed connecting block, which is convenient for disassembly and recycling of the device.

具体实施方式Detailed ways

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

如图1至图4所示,一种电力线路故障检测装置,包括两个移动座1,两个移动座1的内侧均安装有多个线性排列的故障检测模块4,每个故障检测模块4均包括两个对称分布的电动伸缩杆401,电动伸缩杆401的一端固定在移动座1的内壁上,电动伸缩杆401的另一端固定有C形金属片402,两个C形金属片402相互对称,两个C形金属片402的内侧均固定有多个绝缘固定杆408,绝缘固定杆408的一端滑动插接有夹持杆409,夹持杆409的一端插接在绝缘固定杆408内部且与绝缘固定杆408之间安装有夹持弹簧411,夹持弹簧411的两端分别与夹持杆409的端部和绝缘固定杆408的内壁固定,夹持杆409的另一端镶嵌有夹持滚珠410,C形金属片402的外表面固定有检测电流导线403,两个检测电流导线403之间连接有检测组件404,利用两个电动伸缩杆401推动两个C形金属片402相互贴合并对故障电路电线进行夹持,使得两个C形金属片402在电路电线外侧形成一个金属圆筒,电流在金属圆筒中穿过时,会让两个C形金属片402组成的金属圆筒上产生涡流电流,涡流电流会顺着检测电流导线403传递至检测组件404中,随后让装置整体在电路电线外侧进行移动,直至两个C形金属片402上无涡流现象时,此时两个C形金属片402的位置为电路电线故障的位置,因为故障位置无电流,所以两个C形金属片402上涡流现象消失,可以快速定位电路电线故障点位、提高检测效率。As shown in FIGS. 1 to 4 , a power line fault detection device comprises two movable seats 1, a plurality of linearly arranged fault detection modules 4 are installed on the inner sides of the two movable seats 1, each fault detection module 4 comprises two symmetrically distributed electric telescopic rods 401, one end of the electric telescopic rod 401 is fixed to the inner wall of the movable seat 1, a C-shaped metal sheet 402 is fixed to the other end of the electric telescopic rod 401, the two C-shaped metal sheets 402 are symmetrical to each other, a plurality of insulating fixed rods 408 are fixed to the inner sides of the two C-shaped metal sheets 402, one end of the insulating fixed rod 408 is slidably plugged with a clamping rod 409, one end of the clamping rod 409 is plugged into the inside of the insulating fixed rod 408 and a clamping spring 411 is installed between the insulating fixed rod 408, the two ends of the clamping spring 411 are respectively fixed to the end of the clamping rod 409 and the inner wall of the insulating fixed rod 408, and the other end of the clamping rod 409 is inlaid with a clamping ball 410 A detection current wire 403 is fixed on the outer surface of the C-shaped metal sheet 402, and a detection component 404 is connected between the two detection current wires 403. Two electric telescopic rods 401 are used to push the two C-shaped metal sheets 402 to fit each other and clamp the faulty circuit wire, so that the two C-shaped metal sheets 402 form a metal cylinder outside the circuit wire. When the current passes through the metal cylinder, eddy current will be generated on the metal cylinder composed of the two C-shaped metal sheets 402. The eddy current will be transmitted to the detection component 404 along the detection current wire 403, and then the device as a whole will be moved outside the circuit wire until there is no eddy current phenomenon on the two C-shaped metal sheets 402. At this time, the position of the two C-shaped metal sheets 402 is the position of the circuit wire fault. Because there is no current at the fault position, the eddy current phenomenon on the two C-shaped metal sheets 402 disappears, which can quickly locate the fault point of the circuit wire and improve the detection efficiency.

工作原理:使用时,将移动座1置于故障的电路电线下方,随后通过独立电源406向电动伸缩杆401供电,利用两个电动伸缩杆401推动两个C形金属片402相互贴合并对故障电路电线进行夹持,使得两个C形金属片402在电路电线外侧形成一个金属圆筒,电流在金属圆筒中穿过时,会让两个C形金属片402组成的金属圆筒上产生涡流电流,涡流电流会顺着检测电流导线403传递至检测组件404中,C形金属片402在产生涡流电流时会将电流通过检测电流导线403、连接导线4047传递至保护电阻4043,并通过保护电阻4043将电流传递至电流传感器4042,电流传感器4042感知电流后会将信号反馈至处理芯片4044,处理芯片4044在接收信号后会将信号发送至信号发送器4045和定位芯片4046,信号发送器4045将电流传感器4042接收电流的信号反馈至电路控制中心,而定位芯片4046会将此时装置的位置传递至电路控制中心,进行实时检测信息反馈,保证检测数据的时效性;Working principle: When in use, the mobile seat 1 is placed under the faulty circuit wire, and then the electric telescopic rod 401 is powered by the independent power supply 406. The two electric telescopic rods 401 are used to push the two C-shaped metal sheets 402 to fit together and clamp the faulty circuit wire, so that the two C-shaped metal sheets 402 form a metal cylinder outside the circuit wire. When the current passes through the metal cylinder, eddy current will be generated on the metal cylinder composed of the two C-shaped metal sheets 402. The eddy current will be transmitted to the detection component 404 along the detection current wire 403. When the C-shaped metal sheet 402 generates eddy current, the current will pass through the detection wire 403. The current is transmitted to the protection resistor 4043 through the current conductor 403 and the connection conductor 4047, and the current is transmitted to the current sensor 4042 through the protection resistor 4043. After sensing the current, the current sensor 4042 will feed back the signal to the processing chip 4044. After receiving the signal, the processing chip 4044 will send the signal to the signal transmitter 4045 and the positioning chip 4046. The signal transmitter 4045 feeds back the signal of the current sensor 4042 receiving the current to the circuit control center, and the positioning chip 4046 will transmit the position of the device at this time to the circuit control center, so as to conduct real-time detection information feedback and ensure the timeliness of the detection data.

随后让装置整体在电路电线外侧进行移动,装置整体移动过程中定位芯片4046会实时对位置信号进行反馈,直至两个C形金属片402移动到电路电线故障处,此故障处无电流,随后在两个C形金属片402到达故障位置是,两个C形金属片402上因为涡流现象而产生的电流会消失,定位芯片4046会将此信号进行重点反馈,同时电流传感器4042感应不到电流并将信号反馈至处理芯片4044,处理芯片4044通过信号发送器4045将电流传感器4042感应电流消失的信号反馈至电路控制中心,电路控制中心根据信号发送器4045、定位芯片4046的信号反馈对此处电路位置进行记录,可以快速定位电路电线故障点位、提高检测效率。Then, the entire device is moved outside the circuit wires. During the movement of the entire device, the positioning chip 4046 will provide real-time feedback on the position signal until the two C-shaped metal sheets 402 move to the fault location of the circuit wires. There is no current at this fault location. Then, when the two C-shaped metal sheets 402 reach the fault location, the current generated on the two C-shaped metal sheets 402 due to the eddy current phenomenon will disappear. The positioning chip 4046 will focus on feedback of this signal. At the same time, the current sensor 4042 cannot sense the current and feeds back the signal to the processing chip 4044. The processing chip 4044 feeds back the signal of the disappearance of the induced current of the current sensor 4042 to the circuit control center through the signal transmitter 4045. The circuit control center records the circuit position here according to the signal feedback from the signal transmitter 4045 and the positioning chip 4046, so as to quickly locate the fault point of the circuit wires and improve the detection efficiency.
