Description

Technical Field

[0001] This utility model relates to the field of electrified railway power supply, and in particular to a mobile contact network voltage detection device. Background Technology

[0002] Electrified railways refer to railway systems that use electric traction, converting electrical energy into mechanical energy to drive trains along the tracks. Compared to traditional steam locomotives and diesel locomotives, electrified railways have higher operating efficiency, lower energy consumption, and less environmental pollution. In the operation of electrified railways, if there is an abnormality in the electrical connection mechanical device, it will cause a false energization fault in the overhead contact line, which will increase the incidence of train operation accidents. To address this, we propose a mobile overhead contact line voltage detection device. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a mobile contact network voltage detection device. This device uses an inductive component to sense the voltage in the contact network. Once the contact network is confirmed to be energized, a control component controls a signal transceiver to transmit the voltage information to the central control center. This allows staff to respond promptly based on the received signal, and corresponding warning lights are simultaneously emitted. Different colored warning lights are used to indicate the voltage level detected by the device, helping staff make timely judgments. Based on the data from the warning lights and the signal transceiver, staff can then instruct the train to proceed into the station. Therefore, this device effectively prevents false energization faults in the contact network caused by abnormalities in the electrical connection mechanical devices, thus avoiding train operation accidents.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A mobile overhead contact line voltage testing device includes a support mechanism, a reinforcement mechanism installed above the middle part of the support mechanism, and a main body mechanism installed on the side of the lower end of the reinforcement mechanism. The reinforcement mechanism includes a fixed frame, a crossbeam fixedly installed at the outer end of the fixed frame, a warning light fixedly installed at the upper end of the crossbeam, a reinforcement block fixedly installed at the middle of the crossbeam at the outer end of the fixed frame, and a fixing component fixedly installed at the lower end of the reinforcement block. A bolt is installed in the internal thread of the fixing component. The crossbeam mounts the warning light at a high position on the device. When the warning light is set, it will provide an early warning based on the power level sensed by the device, using different colored warning lights to help staff make timely judgments.

[0005] Furthermore, the support mechanism includes a base, a support rod fixedly mounted on the upper end of the base, a mounting frame fixedly mounted on the middle of the support rod, a fixing block fixedly mounted on the middle of the outer side of the upper end of the mounting frame, an auxiliary light fixedly mounted on the outer side of the lower end of the mounting frame, a lightning protection component fixedly mounted on the upper end of the support rod, and a reinforcement structure provided on the base to ensure high stability of the lower end of the device after installation, improving safety when used outdoors. The lightning protection component at the top of the support rod ensures that the height of the device is not affected by lightning strikes during thunderstorms.

[0006] Furthermore, the main structure includes a voltage detector box. An induction component is fixedly installed on the upper side of the voltage detector box. A signal transceiver is fixedly installed in the middle of the outer end of the voltage detector box. A control component is fixedly installed on the outer end of the voltage detector box outside the signal transceiver. A baffle is fixedly installed on the outer end of the voltage detector box above the signal transceiver. A protective box is fixedly installed on the outer end of the voltage detector box below the baffle. When the device senses grid power, the signal transceiver is used to transmit grid power information to the central control center in a timely manner, so that staff can respond promptly based on the received signal.

[0007] Furthermore, the fixing frame is a ring structure, and the fixing frame is fixedly installed above the middle part of the support rod. The crossbeams are symmetrically distributed at the left and right ends of the fixing frame, and the fixing frame is used to fix the crossbeams.

[0008] Furthermore, the warning lights are evenly distributed at the upper end of the crossarm, the fasteners are L-shaped, and there are two fasteners.

[0009] Furthermore, the middle part of the mounting frame has a ring structure, and the fixing block and the fixing member have the same structure.

[0010] Furthermore, the lower end of the voltage tester is fixedly connected to the upper end of the mounting bracket via a fixing block, and the upper end of the voltage tester is fixedly connected to the lower end of the reinforcing block via a fastener.

[0011] Furthermore, the protective box has a hollow structure, and the upper end of the baffle has an arc-shaped structure.

[0012] In summary, this utility model has the following beneficial effects: 1. By sensing the electrical grid through an induction component, the overhead contact line is energized. Once the contact line is confirmed to be live, the control component transmits the grid voltage information to the central control center via a signal transceiver. This allows staff to respond promptly based on the received signal, and corresponding warning lights are issued simultaneously. Based on the level of grid voltage sensed by the device, different colored warning lights provide early warnings, helping staff make timely judgments. Staff use the data from the warning lights and the signal transceiver to indicate whether the train is allowed to enter the station. Therefore, this device effectively prevents false energization faults in the contact line caused by abnormalities in the electrical connection mechanical devices, thus avoiding train operation accidents. 2. By setting up a baffle, the top of the lower protective box is not easy to accumulate dust. Its arc structure has low friction and also has the advantages of guiding airflow. The hollow structure of the protective box encloses the signal transceiver and control components, which does not affect the signal release of the two, and also has the function of preventing bumps.
