Description

Technical Field

[0001] This utility model relates to the technical field of railway signal power supply panels, specifically to a railway signal power supply panel with a protection device. Background Technology

[0002] The railway signal power supply panel is a key piece of equipment to ensure the safety of railway transportation. It consists of multiple modules (such as rectifier modules, inverter modules, etc.). The electronic components generate a lot of heat when they are working, and timely heat dissipation is required to ensure stable operation. Currently, the internal cooling of railway signal power supply panels generally uses fans for forced air cooling, and dust filters are installed at the air inlets to block dust. However, after long-term use, the dust filters are easily clogged by dust, resulting in reduced ventilation and heat dissipation efficiency, which may cause equipment overheating failure in severe cases. Existing dustproof nets are mostly fixed with screws or installed with simple clips. Cleaning or replacement requires disassembling the screws or laboriously prying open the clips, which is inconvenient. In addition, the fan inlet is completely exposed during maintenance, and the equipment has to be stopped, which affects the continuous stability of the railway signaling system. Therefore, a railway signaling power supply panel with a protection device is proposed. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a railway signal power supply panel with a protection device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a railway signal power supply panel with a protection device, including a railway signal power supply panel, wherein a wind-cooling protection device is embedded on one side of the cabinet of the railway signal power supply panel, and an exhaust vent is opened through the other side of the cabinet of the railway signal power supply panel. The air-cooled protection device includes an exhaust fan. The air inlet of the exhaust fan is fixedly connected to an installation panel. The installation panel is fixedly installed to the cabinet of the railway signal power supply panel by bolts. A detachable side frame is provided on one side of the installation panel. A dustproof net is provided on the side of the side frame near the installation panel. The outer periphery of the dustproof net is glued and fixed to the side frame.

[0005] By adopting the above technical solution and using components composed of air-cooled protection devices, a dust-proof air-cooled structure is provided for the railway signal power supply panel.

[0006] Specifically, the mounting panel has sliding grooves at both ends, and the side frame is integrally connected to the two ends of the side closest to the mounting panel with sliders corresponding to the sliding grooves. The side frame is slidably connected to the sliding grooves of the mounting panel through the sliders. The surfaces of the slide groove and the slider are equidistantly embedded with corresponding magnets, and the magnets are glued and fixed to the corresponding slide groove and slider.

[0007] The dustproof structure, consisting of the side frame and dustproof net, can be quickly replaced via a simple sliding plug-in connection and is magnetically installed using magnets. It is flexible and convenient to use. When there is a lot of dust adhering to the dustproof net, affecting the airflow of the exhaust fan, maintenance personnel can insert another set of side frames with dustproof nets from the top or bottom of the slide groove and push them out to remove the original side frame for quick replacement. This facilitates quick dust removal and maintenance without exposing the air inlet of the exhaust fan, ensuring the reliability of continuous operation of the exhaust fan.

[0008] Specifically, the air inlet end of the exhaust fan casing is equipped with a protective railing consisting of several sets of crossbars.

[0009] Specifically, a wind speed sensor and a PLC controller are bolted to the inside of the railway signal power supply panel. The top of the exhaust fan casing has a through hole for the wind speed sensor probe to pass through, and the wind speed sensor probe is set at the exhaust end of the exhaust fan through the through hole.

[0010] Specifically, an LED indicator light is bolted to the top of one side of the railway signal power supply panel; the output terminal of the wind speed sensor is electrically connected to the input terminal of the PLC controller via a wire; and the output terminal of the PLC controller is electrically connected to the input terminal of the LED indicator light via a wire.

[0011] By adopting the above technical solution, the air volume of the exhaust fan is detected by the wind speed sensor and transmitted to the PLC controller. When the dust filter surface has a large amount of dust and the air volume weakens, the PLC controller controls the LED indicator light to light up based on the personnel's settings. This allows daily maintenance personnel to quickly observe the situation and replace or maintain the air-cooled protection device, thus ensuring the protection of air-cooled heat dissipation in the railway signal power supply panel.

[0012] The beneficial effects of this utility model are as follows: By using the sliding connection between the slider and the groove, combined with the magnetic adsorption fixing method, the side frame and dustproof net can be quickly disassembled and assembled. Maintenance personnel can push the spare side frame in from one side and push the blocked side frame out from the other side to complete the replacement without stopping the machine. The whole process takes very little time, ensuring the continuous operation of the heat dissipation system and the high availability of the equipment. It is particularly suitable for the maintenance scenarios in railway systems where every second counts. By setting a wind speed sensor to monitor the actual working air volume of the exhaust fan in real time and transmitting the data to the PLC controller, when the dustproof net is blocked and the air volume is lower than the preset threshold, the PLC controller will immediately light up the LED indicator light to actively remind the maintenance personnel to replace it. This helps the maintenance personnel to change the operation mode from regular maintenance to on-demand maintenance, avoiding the risk of heat dissipation failure due to failure to detect blockage in time, and also preventing the waste of resources caused by over-maintenance.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-3 As shown, the railway signal power supply panel with protection device described in this utility model includes a railway signal power supply panel body 1, an air-cooled protection device 2, a wind speed sensor 3, a PLC controller 4, and an LED indicator light 5.

[0017] The air-cooled protection device 2 is fixed to the side of the power supply cabinet by bolts through its mounting panel 22. When the exhaust fan 21 is working, the external cold air passes through the dustproof net 26, the protective railing 29 and the exhaust fan 21 in sequence under negative pressure and is blown into the power supply cabinet. Finally, the hot air is discharged from the exhaust port 11 on the opposite side, forming an effective heat dissipation air duct.

[0018] The mounting panel 22 has vertical grooves 23 at both ends, and the inner ends of the side frame 24 have integrated sliders 25 that match the grooves 23. When replacing, hold the side frame 24, align the sliders 25 with the port of the groove 23, and slide them down along the groove 23. When the side frame 24 moves into place, the magnets 27 pre-embedded in the sliders 25 and the groove 23 attract each other, so that the side frame 24 is firmly attached to the mounting panel 22, and the installation is completed. When there is a lot of dust on the dustproof net 26, which affects the airflow of the exhaust fan 21, the maintenance personnel can insert another set of side frames 24 with dustproof nets 26 from the top or bottom of the groove 23 and push it to push out the original side frame 24, which can be quickly replaced. This facilitates quick replacement and cleaning maintenance without exposing the air inlet of the exhaust fan 21, ensuring the reliability of the continuous operation of the exhaust fan 21.

[0019] The probe of the wind speed sensor 3 extends into the air outlet channel of the exhaust fan 21 through the perforation 28. The probe of the wind speed sensor 3 can be fixed to the housing of the exhaust fan 21 by bolts or adhesive. The wind speed sensor 3 monitors the air volume signal in real time and transmits it to the PLC controller 4. The PLC controller 4 is preset with a threshold range of normal air volume. When the dust screen 26 gradually becomes clogged, causing the monitored air volume to continuously fall below the set threshold, the PLC controller 4 determines that maintenance is required and then outputs a signal to control the LED indicator light 5 installed on the outside of the cabinet to light up, giving the staff a clear visual maintenance instruction.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
