Description

Technical Field

[0001] This utility model relates to the field of power line technology, specifically a real-time load monitoring and fault identification device for railway power lines. Background Technology

[0002] With the development of technology and the construction of public transportation, more and more railway lines are being built and developed. The use of railways is inseparable from the high-voltage lines of railway signal power supply. These high-voltage lines include automatic block lines and power through lines. They are distributed along the railway line and are connected to a power supply section by automatic blocking or through lines from two adjacent substations. However, the lines are mutually redundant. Once a line or substation fails, the railway traffic signal will malfunction, resulting in a railway accident. Therefore, the stable operation of railway power through lines is very important. However, at present, there is a lack of fault location and diagnosis technology for power through lines. When a line fails, the troubleshooting and recovery are relatively slow, and fault diagnosis is relatively difficult. Utility Model Content

[0003] The purpose of this invention is to provide a real-time load monitoring and fault identification device for railway power lines, so as to solve the problem of difficulty in troubleshooting and restoring power line faults mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a real-time load monitoring and fault identification device for a railway power line, comprising a housing, a load detector fixedly installed inside the housing, with the input and output terminals of the load detector passing through the housing, a through hole on the outer surface of one end of the housing, an inclined interior design, and a cabinet door rotatably mounted on the side surface of the housing, LED flashing lights evenly distributed on the outer surface of the housing, and a signal transmitting mechanism inside the housing, which can transmit real-time load information of the line to a monitoring terminal, facilitating real-time monitoring of the load on the power line.

[0005] Preferably, the signal transmitting mechanism includes: a signal generating locator, which is fixedly installed inside the housing and located on one side of the load detector. The load detector is connected to the signal generating locator. An external antenna is fixedly installed on one side surface of the housing and connected to the signal generating locator. The cable between the signal generating locator and the external antenna passes through a through hole in the housing.

[0006] By adopting the above technical solution, the power line can be monitored in real time by load detectors, and the data obtained during the detection can be transmitted to the outside through a signal generator locator. The signal strength during information exchange can be improved by connecting an external antenna, so that the device can transmit the load data detected in real time to the terminal during use. In the event of a fault in the power line, the location of the fault can be marked and located by the signal generator locator, and the transmitted data can help to determine the type of fault, thereby speeding up the diagnosis and troubleshooting of the fault.

[0007] Preferably, a solar panel is rotatably mounted on the outer surface of the housing, and a rotation adjustment mechanism is provided inside and outside the housing. The rotation adjustment mechanism allows the device to adjust the angle of the solar panel to the maximum extent, facilitating the solar panel to generate electricity.

[0008] By adopting the above technical solution, the electricity converted from solar radiation can be stored through solar panels, so that the device can be temporarily powered when the through line is powered off or malfunctions. It is also convenient to send signals to help workers find the fault point after the power is off.

[0009] Preferably, the rotation adjustment mechanism includes: an electric push rod, which is rotatably mounted on the outer surface of the housing, the output end of the electric push rod is rotatably connected to the solar panel, the electric push rod is located below the solar panel, and a storage battery is fixedly installed inside the housing.

[0010] By adopting the above technical solution, the solar panel can be rotated on the outer surface of the box by adjusting the electric push rod, so that the solar panel can face the sun at a suitable angle without manual adjustment, and the solar panel can always face the sun at a suitable angle.

[0011] Preferably, a rubber opening is provided through the outer surface of the end of the housing away from the electric push rod, and the outer surface of the rubber opening is in contact with the outer surface of the through hole of the housing. The rubber opening is petal-shaped. An exhaust shield is fixedly installed on the side surface of the housing away from the external antenna, and an exhaust fan is fixedly installed on the side surface of the exhaust shield and the exhaust shield. An air inlet and drain outlet are fixedly opened on the outer surface of the housing near the rubber opening, and the air inlet and drain outlet are located at the lowest point inside the housing.

[0012] By adopting the above technical solution, the petal-shaped design of the rubber opening allows the wiring entering the box to fit tightly against the rubber opening, minimizing gaps between the wiring and the rubber opening and reducing the chance of water entering the box. The exhaust shield effectively blocks rainwater from entering the box. The tilted design of the box allows water that enters the box through gaps to drain out through the air inlet and drain outlets, preventing water from entering the box when the exhaust fan is running. Even if a small amount of water enters, it can be drained out through the air inlet and drain outlets.

[0013] Preferably, a sliding slot is fixedly installed on the outer surface of the housing, and a plug-in fastening mechanism is provided between the sliding slot and the housing. The plug-in fastening mechanism makes the installation and fixation of the device more convenient and simple.

[0014] By adopting the above technical solution, the installation of the device can be carried out without the box, which reduces the difficulty of installation and saves a lot of physical strength for the installation workers.

[0015] Preferably, the plug-in fastening mechanism includes: an elastic plug rod, which is slidably installed inside the housing, and one end of the elastic plug rod penetrates the outer surface of the housing. One end of the elastic plug rod is located inside the sliding slot. A plug-in fixing rod is slidably inserted into the outer surface of the sliding slot, and a clamping block is installed through the outer surface of the plug-in fixing rod. An arc-shaped groove is formed between the clamping block and the outer surface of the plug-in fixing rod. A fixing nut is threaded onto the outer surface of the plug-in fixing rod, and the fixing nut fits against the outer surface of the clamping block. The elastic plug rod is plugged into the plug-in fixing rod, and the plug-in fixing rod is engaged with the elastic plug rod.

[0016] By adopting the above technical solution, the plug-in fixing rod, clamping block, and fixing nut can be fixedly installed on the railway power pole through the clamping arrangement of the plug-in fixing rod, clamping block, and fixing nut, without having to carry the box body during installation. This reduces the weight of the components to be handled during installation. After installation, the box body can be inserted into the plug-in fixing rod, so that the plug-in fixing rod can be inserted into the sliding slot, allowing the elastic plug rod to engage with the plug-in fixing rod. This facilitates the installation and fixation of the box body, and the box body can only be removed after it has been opened.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the real-time load monitoring and fault identification device for railway power lines:

[0018] 1. The device can be powered through the power line, enabling the load detector to work and transmit the collected data to the outside in real time through the signal generator locator. The signal strength is enhanced by an external antenna, reducing the impact of the enclosure on the signal strength. In the event of a fault or damage to the power line, the signal generator locator can send a signal for location and calibration. In conjunction with the flashing of LED lights, workers can quickly identify and locate the fault after a power line failure by using the location signal, the flashing of LED lights, and the transmitted data.

[0019] 2. The rotation angle of the solar panel can be adjusted by the quantitative extension of the electric push rod, so that the solar panel faces the sun at a suitable angle, allowing the solar panel to generate electricity and store the electricity in the battery so that it can still provide power after the power line is cut off. At the same time, the operation of the exhaust fan allows the outside air to enter the box through the air inlet and drain and be discharged out through the exhaust shield. The exhaust shield reduces the chance of water entering the box. The inclined design of the box and the air inlet and drain allow water that enters the box to be discharged out through the air inlet and drain, reducing water accumulation in the box. This allows the device to continue to operate for a period of time after the power line is cut off, making it easier for workers to find the faulty section for repair.

[0020] 3. When installing the device, simply place the plug-in fixing rod in the appropriate position on the metal rod, then insert the clamping block into the inside of the plug-in fixing rod, and then screw in the fixing nut to fix the plug-in fixing rod and the clamping block on the metal rod. Then, insert the sliding slot into the inside of the plug-in fixing rod so that the plug-in fixing rod can be plugged into the elastic plug rod. This eliminates the need to carry the box during installation, and disassembly can only be done by opening the box and moving the elastic plug rod, reducing the weight when installing and taking out the device and making the installation of the device more convenient.

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a real-time load monitoring and fault identification device for a railway power line, including a housing 1. A load detector 5 is fixedly installed inside the housing 1, and the input and output terminals of the load detector 5 pass through the housing 1. A through hole is opened on the outer surface of one end of the housing 1, and the interior of the housing 1 is designed to be inclined. A cabinet door is rotatably installed on the side surface of the housing 1. LED flashing lights 17 are evenly distributed on the outer surface of the housing 1. A signal transmitting mechanism is set inside the housing 1. The real-time load information of the line can be sent to the monitoring terminal through the signal transmitting mechanism, which facilitates the real-time monitoring of the load of the power line.

[0030] The load detector 5 can monitor the load of the railway power line in real time. The through holes on the outer surface of the box 1 facilitate the insertion and installation of the line. The box 1 can also improve the safety protection of electronic components and reduce the probability of damage to components when vehicles pass by. At the same time, the position of the through holes in the box 1 can effectively prevent external water from entering the interior of the box 1. When a line fault occurs, the LED flashing light 17 will flash automatically, so that maintenance workers can quickly find the device by the flashing of the LED flashing light 17 when they arrive at the location, which facilitates the search and diagnosis of faulty sections between lines.

[0031] The signal transmitting mechanism includes: a signal generating locator 6, which is fixedly installed inside the housing 1 and located on one side of the load detector 5. The load detector 5 is connected to the signal generating locator 6. An external antenna 7 is fixedly installed on one side surface of the housing 1 and is connected to the signal generating locator 6. The cable between the signal generating locator 6 and the external antenna 7 passes through the through hole of the housing 1.

[0032] When the power line fails and cannot be connected, the load detector 5 will send a signal through the signal generator locator 6 to transmit the information and transmit the location. The signal strength will be amplified by the external antenna 7 to reduce the chance of the signal being blocked inside the enclosure 1. This allows the signal to be transmitted to the outside and located after the power line is damaged, and the signal will be accompanied by the flashing of the LED flashing light 17. The transmitted data will help to determine the type of fault, allowing maintenance workers to quickly find the faulty section for repair.

[0033] A solar panel 2 is rotatably mounted on the outer surface of the housing 1. A rotation adjustment mechanism is provided inside and outside the housing 1. The rotation adjustment mechanism allows the device to adjust the angle of the solar panel 2 to the maximum extent, so that the solar panel 2 can generate electricity. The rotation adjustment mechanism includes an electric push rod 3, which is rotatably mounted on the outer surface of the housing 1. The output end of the electric push rod 3 is rotatably connected to the solar panel 2. The electric push rod 3 is located below the solar panel 2. A storage battery 4 is fixedly installed inside the housing 1.

[0034] The activation of the electric push rod 3 can drive the solar panel 2 to rotate on the outer surface of the housing 1, allowing the solar panel 2 to rotate and change its angle so that the solar panel 2 always faces the sun, maintaining the power generation of the solar panel 2, and storing the power generated by the solar panel 2 into the battery 4. This facilitates short-term power supply to the device after a power outage due to a fault in the power transmission line, allowing maintenance workers to still receive signals after a power outage to locate and determine the faulty section of the power transmission line.

[0035] A rubber opening 10 is provided through the outer surface of the end of the housing 1 away from the electric push rod 3, and the outer surface of the rubber opening 10 is in contact with the outer surface of the through hole of the housing 1. The rubber opening 10 is petal-shaped. An exhaust shield 8 is fixedly installed on the side surface of the end of the housing 1 away from the external antenna 7, and an exhaust fan 9 is fixedly installed on the side surface of the exhaust shield 8. An air inlet and drain outlet 11 is fixedly opened on the outer surface of the end of the housing 1 near the rubber opening 10, and the air inlet and drain outlet 11 is located at the lowest point inside the housing 1.

[0036] The petal-shaped design of the rubber inlet 10 allows it to fit snugly against the wiring when passing through, reducing the chance of debris entering the enclosure 1 and the chance of rainwater entering the enclosure 1 during external rainfall. The exhaust fan 9 allows external air to enter the enclosure 1 through the air inlet and drain outlet 11, allowing air to pass through the enclosure 1 and be discharged through the exhaust shield 8, reducing the operating temperature inside the enclosure 1. The exhaust shield 8 also prevents external water from entering the enclosure 1. The inclined design of the enclosure 1 and the air inlet and drain outlet 11 allow any small amount of water that enters the enclosure 1 to be discharged outwards, preventing water from damaging or affecting the components inside the enclosure 1.

[0037] A sliding slot 13 is fixedly installed on the outer surface of the housing 1, and a plug-in fastening mechanism is provided between the sliding slot 13 and the housing 1. The plug-in fastening mechanism makes the installation and fixation of the device more convenient and simple. The plug-in fastening mechanism includes: an elastic plug rod 12, which is slidably installed inside the housing 1, and one end of the elastic plug rod 12 penetrates the outer surface of the housing 1. One end of the elastic plug rod 12 is located inside the sliding slot 13. A plug-in fixing rod 14 is slidably inserted into the outer surface of the sliding slot 13, and a clamping block 15 is installed through the outer surface of the plug-in fixing rod 14. An arc-shaped groove is opened on the outer surface of the clamping block 15 and the plug-in fixing rod 14. A fixing nut 16 is threadedly installed on the outer surface of the plug-in fixing rod 14, and the fixing nut 16 fits against the outer surface of the clamping block 15. The elastic plug rod 12 is plugged into the plug-in fixing rod 14, and the plug-in fixing rod 14 is engaged with the elastic plug rod 12.

[0038] When installing the device, simply attach the plug-in fixing rod 14 to the metal rod on the side of the railway, insert the clamping block 15 into the plug-in fixing rod 14, and tighten the clamping block 15 and the plug-in fixing rod 14 by screwing in the fixing nut 16. Then, insert the sliding slot 13 into the plug-in fixing rod 14, allowing the plug-in fixing rod 14 to push the elastic plug 12 to move, and make the elastic plug 12 and the plug-in fixing rod 14 plug and fix it. This will fix the box 1 on the plug-in fixing rod 14, reducing the weight of the parts that need to be handled during installation, reducing the difficulty of installation, and improving the convenience of installing the device. Moreover, the box 1 can only be removed by moving the elastic plug 12 after the box 1 is opened, which makes it convenient to assemble and maintain the device.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
