Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a modular fire linkage controller. Background Technology

[0002] Modular fire alarm control systems are important equipment in fire protection systems. They need to be connected to multiple modular devices via cables to achieve linkage control functions. In practical applications, the controller itself needs to be connected to a large number of external cables, including power lines, signal lines, and equipment control lines.

[0003] In practical applications, due to the large number of connected devices, the number of external cables also increases accordingly. However, existing controllers lack a dedicated cable sorting and organization structure, which makes these cables prone to tangling and messiness. This chaotic state not only increases the difficulty of wiring but also causes inconvenience to subsequent maintenance work. It is difficult for staff to quickly locate the target cable, and the pulling between cables may also affect the stability of signal transmission and cause malfunctions.

[0004] To address the aforementioned issues, this utility model document proposes a modular fire alarm linkage controller. Utility Model Content

[0005] This utility model provides a modular fire alarm control system, which solves the problem of messy external cables in existing modular fire alarm control systems.

[0006] This utility model provides the following technical solution: A modular fire alarm control panel includes a modular fire alarm control panel body. A maintenance plate is fixed to the cabinet opening on the back of the modular fire alarm control panel body by screws. Two rectangular wire holes are symmetrically arranged on the upper part of the maintenance plate. A corresponding cable management plate is arranged below the rectangular wire holes. Multiple display blocks are fixedly arranged at equal intervals on the outer wall of the cable management plate. A corresponding U-shaped cable clamp is fixedly arranged at the other end of the display block.

[0007] More preferably, two L-shaped plugs are symmetrically fixed on the inner wall of the cable management plate, and a fixing block for engaging the corresponding L-shaped plugs is fixed on the outer wall of the inspection plate, with a rectangular insertion hole vertically penetrating the center of the fixing block.

[0008] More preferably, a vertical slot is provided on the side wall of the display block, and an information nameplate is vertically inserted into the vertical slot.

[0009] In a further preferred embodiment, a corresponding rectangular frame is fixedly installed at the ventilation openings on both sides of the modular fire linkage controller body. A horizontal slot is provided inside the rectangular frame, and a heat dissipation plate is horizontally inserted into the horizontal slot. The heat dissipation plate is provided with multiple heat dissipation holes.

[0010] More preferably, a long handle is fixedly provided in the center of the outer wall of the heat sink.

[0011] More preferably, the bottom of the modular fire alarm control unit is provided with a raised base, and a ramp is fixedly provided at the notch on one side of the raised base.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] The working principle and usage process of this technical solution are as follows: Before use, place the modular fire alarm controller body on the raised base at the bottom to increase the distance between the modular fire alarm controller body and the mounting surface and prevent the bottom from getting damp. Then, align the L-shaped plug of the cable management board with the rectangular plug hole of the fixing block on the inspection board and insert it vertically to achieve quick snap-fit ​​fixation between the cable management board and the inspection board. Then, pass the cables connecting the controller to the external modular equipment through the two rectangular cable holes on the inspection board in a classified manner, and embed them into the U-shaped cable clips on the outer wall of the cable management board according to the cable function to achieve orderly cable arrangement. At the same time, insert the information nameplate that indicates the purpose of the cable and the corresponding module information vertically into the vertical slot of the display block to complete the visual identification of the cable. Finally, fix the inspection board to the cabinet opening on the back of the modular fire alarm controller body with screws. The heat sink with multiple ventilation holes is then inserted horizontally into the corresponding ventilation openings on both sides of the controller through the horizontal slots within the rectangular frame. The ventilation holes allow for airflow and heat dissipation during controller operation. The long handle on the outer wall of the heat sink facilitates subsequent disassembly. During controller operation, the orderly arranged cables prevent tangling and pulling, ensuring stable signal transmission. The heat sink continuously dissipates internal heat through the ventilation holes. When maintenance is required, the heat sink can be pulled out by holding the long handle to clean dust or inspect the heat dissipation structure. The target cable can be quickly located using the information label, adjusted or repaired, and then reinstalled.

[0014] This utility model has the following beneficial effects: 1. This utility model enables the classified insertion of cables through rectangular wire holes, and with the orderly fixation of U-shaped wire clamps, it helps to change the current situation of messy and tangled external cables of existing modular fire linkage controllers, avoids signal transmission failures caused by cable pulling, and at the same time, the information nameplate can quickly identify the corresponding module of the cable, thereby improving the identification during wiring and maintenance. 2. In this utility model, the cable management board is fixed by the L-shaped plug and the rectangular plug hole of the fixing block, which can be disassembled and assembled without additional tools, making disassembly and assembly convenient; the pluggable heat sink ensures air circulation when the controller is working through the heat dissipation holes. When dust accumulates in the heat dissipation holes, the heat sink can be pulled out for cleaning by holding the long handle, making maintenance simple and not affecting the overall operation of the controller; the raised base helps to improve the moisture resistance of the bottom of the controller.
