Description

Technical Field

[0001] This utility model relates to the field of emergency lighting technology, and in particular to a power supply for fire emergency lighting. Background Technology

[0002] In modern building safety systems, fire emergency lighting is a crucial facility for ensuring safe evacuation and firefighting operations. It must not only meet basic lighting needs in everyday environments but also guide people through clear escape routes in complex scenarios such as fires and earthquakes, including smoke-filled and power outage situations, ensuring firefighters can conduct rescue operations smoothly. As buildings become increasingly tall, large, and complex, the design and layout of fire emergency lighting are becoming more sophisticated. It requires comprehensive consideration of factors such as building structure, functional zoning, and evacuation routes, employing intelligent control systems to achieve precise activation, brightness adjustment, and status monitoring of emergency lighting to meet the safety needs of different emergency scenarios.

[0003] A reliable power supply for fire emergency lighting is a core prerequisite for its effectiveness in emergencies. Under normal circumstances, the emergency lighting system is powered by an external power source to maintain daily operation. However, when a disaster such as a fire causes the external power supply to be cut off, a rapid switch to backup power is necessary to ensure uninterrupted operation of the emergency lighting. This process relies on advanced power switching devices and stable energy storage equipment, such as high-performance battery packs. The battery packs are normally in a charging standby state. Once the external power supply is interrupted, the switching device immediately responds, switching the power supply circuit to the battery to provide continuous power to the emergency lighting fixtures, ensuring they can continuously illuminate evacuation routes in critical moments and buy valuable time for personnel to evacuate safely.

[0004] Patent document CN223090591U discloses an emergency lighting power supply protection device with a heat dissipation structure. The technical solution is as follows: An emergency lighting power supply protection device with a heat dissipation structure includes a protective shell, a protective door, heat dissipation holes, a storage slot, a magnetic absorbing sheet, a filter screen, and a semi-circular groove. The protective shell, installed in front of a wall, has a protective door on its front side. A heat dissipation hole is provided through the protective door. A storage slot is provided on the front side of the protective door, and the filter screen is placed inside the storage slot. A magnetic absorbing sheet is adhered to the storage slot, and the filter screen is attracted to the front end of the magnetic absorbing sheet. A semi-circular groove is provided on the filter screen, with opposing semi-circular grooves on the left and right sides. This invention, by providing a storage slot on the front side of the heat dissipation holes and fixing the filter screen inside the storage slot with the magnetic absorbing sheet, prevents dust from entering the protective device. Furthermore, the semi-circular groove provides a leverage point for workers to disassemble the filter screen, reducing the difficulty of filter screen replacement.

[0005] As in the prior art of the aforementioned patent, the protective shell is fixed to the outside of the power supply by bolt connection. Each time maintenance is required, the bolts need to be unscrewed, which is a cumbersome disassembly process. In addition, fire emergency lights are generally installed at high places. If the outer shell is not properly stored after being removed, it is easy for it to fall or be lost. Utility Model Content

[0006] The purpose of this utility model is to provide a power supply for fire emergency lighting to overcome the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a power supply for fire emergency lighting, comprising a mounting base and a power supply body. The mounting base has multiple mounting bolts threaded onto its edge. Two mounting brackets are fixedly mounted on the mounting base, each bracket has a lamp holder fixedly mounted on it. A lamp body is fixedly mounted on each lamp holder, and a protective cover is provided over the lamp body. A power supply base is fixedly mounted on the mounting base, and multiple fixing bolts are threaded onto the power supply base. A mounting frame is fixedly mounted at the bottom of the power supply body, and the mounting frame has multiple screw holes. The multiple fixing bolts are threaded into the screw holes, and nuts are threaded onto the ends of the multiple fixing bolts. A protective outer shell covers the power supply body, and the protective outer shell, multiple nuts, and fixing bolts are connected via a hook-and-loop assembly.

[0008] As a further description of the above technical solution: the mounting assembly includes an extension plate fixedly installed on one side of the protective shell, the extension plate having multiple mounting holes, and each of the multiple mounting holes corresponding to a multiple fixing bolts and nuts.

[0009] As a further description of the above technical solution: the upper part of the mounting hole is provided with a fixing plate, the fixing plate is provided with a mounting groove, and the mounting groove is adapted to the end of the fixing bolt.

[0010] As a further description of the above technical solution: when the ends of the plurality of fixing bolts are hooked into the inside of the hooking groove, the other side of the protective shell away from the extension plate is pressed against the plurality of nuts.

[0011] As a further description of the above technical solution: the surface of the protective shell is provided with a plurality of heat dissipation grooves, and a filter screen is provided inside the plurality of heat dissipation grooves.

[0012] As a further description of the above technical solution: the lamp holder has a first threaded hole on the side near the power supply body, and the power supply body has second threaded holes on both sides. A double-ended bolt is threaded between the first threaded hole and the second threaded hole. The protective shell has through grooves on both sides, and the two through grooves cover the outside of the two double-ended bolts.

[0013] This utility model provides a power supply for fire emergency lighting. It has the following advantages: The extension plate on the protective housing has mounting holes that can be attached to multiple fixing bolts and nuts, enabling the installation of the protective housing. Due to gravity, the protective housing slides downwards, at which point the nuts are inside the mounting holes, and the ends of the fixing bolts are engaged inside the mounting grooves. The mounting grooves engage with the threaded grooves at the ends of the fixing bolts, preventing them from falling off. Disassembly is also convenient; simply lift the protective housing upwards so that the mounting grooves are away from the ends of the fixing bolts, and the protective housing can be removed. After the protective housing is removed from the power supply body, it is attached to the bottom of the power supply body via the mounting assembly, achieving the effect of preventing loss and falling.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description
