Description

Technical Field

[0001] This utility model relates to the technical field of marine electrical equipment, and in particular to a marine multi-channel switch alarm device. Background Technology

[0002] Traditional alarm devices include fire alarms, manual alarms, and smoke detectors, which are mainly installed in the ship's control room or cabin. They use audible and visual alarms to ensure that all crew members can hear them and take appropriate measures. However, with the increase in marine equipment, the number of fault points that need to be addressed has also increased. This makes single-function alarm devices increasingly unsuitable for the needs of modern ships. Therefore, there is a need for an alarm device that integrates multiple switching signals to deal with various emergencies such as fire, flooding, smoke, and separator malfunctions. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a marine multi-channel switch alarm device, comprising a panel, a cover plate, a main board assembly, and a back plate arranged sequentially from front to back. The cover plate is provided with studs and mounting holes. The main board assembly is fixedly connected to the cover plate by studs. The back plate is connected to the cover plate by mounting holes. The cover plate and the back plate together form a mounting cavity for accommodating the main board assembly. The main board assembly includes a circuit board, a terminal block electrically connected to the back of the circuit board, and an indicator light, an electronic button, and a buzzer electrically connected to the front of the circuit board. The terminal block is provided sequentially with an input terminal for external alarm signals, a communication terminal for external extension boards, an output terminal for controlling the operation of the indicator light and the buzzer, and a power terminal for external power supply.

[0004] Using the above technical solution, this utility model is embedded in the cabinet through mounting holes. It has 8 input terminals for switch quantity detection, which can detect the status of various switch quantity signals on the ship and generate corresponding audible and visual alarms through the output terminals. The communication terminal sends alarm information to the extension board through the RS485 communication protocol, thereby realizing simultaneous alarm in multiple areas of the ship's cabin. The electronic buttons include a test button, a mute button, and a dimming button, which are used for periodic testing, manual alarm cancellation, and indicator light brightness adjustment, respectively, thereby meeting the basic functional requirements of the alarm device.

[0005] As a preferred embodiment of this utility model, the cover plate is provided with studs arranged in a rectangular shape, the studs are provided with raised parts and threaded parts, the circuit board is provided with through holes adapted to the threaded parts, the circuit board abuts against the raised parts, and the threaded parts pass through the through holes and are threadedly connected to the circuit board.

[0006] Using the above technical solution, the stud is welded to the cover plate. The raised part is used to control the distance between the electronic button and the panel, so that the electronic button can work normally. The threaded part and the through hole are distributed in the same position, which makes the circuit board easy to install and improves production efficiency.

[0007] As a preferred embodiment of this utility model, the terminal block is provided with an insulating base, a locking screw, pins and a fixing sleeve. The insulating base has pins and locking screws arranged in a straight line. The pins pass through the fixing sleeve and are electrically connected to the circuit board. The two ends of the fixing sleeve abut against the insulating base and the circuit board.

[0008] Furthermore, the wiring harness is located at the opening of the mounting cavity.

[0009] By adopting the above technical solution, when welding the terminal block, since each fixing sleeve has the same length, the insulating base is parallel to the circuit board, which improves welding efficiency. Since most pins are exposed at the opening of the mounting cavity, the wiring at that point can be checked with a multimeter to see if it is normal, which greatly facilitates daily maintenance.

[0010] As a preferred embodiment of this utility model, the cover plate is provided with a first opening slot for accommodating indicator lights, electronic buttons and buzzers.

[0011] Furthermore, the panel is provided with a frosted layer and a colored layer. The colored layer is provided with a second opening groove corresponding to the first opening groove, and the frosted layer is provided with a protrusion adapted to the electronic button.

[0012] Using the above technical solution, the frosted layer is a semi-transparent material. By attaching a color layer, a preset pattern is formed, allowing the light from the indicator light to pass through the first opening slot, the second opening slot, and the frosted layer, thereby displaying the status prompt of the alarm device. Each electronic button has a corresponding protrusion, which allows the electronic button with the corresponding function to be accurately located, realizing the function control of testing, silencing, and dimming of the alarm device.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This utility model is mainly embedded in the cabinet and has 8 input terminals for switch quantity detection. It can detect the status of various switch quantity signals on the ship and generate corresponding audible and visual alarms through the output terminals. The communication terminal sends alarm information to the extension board through the RS485 communication protocol, thereby realizing simultaneous alarm in multiple areas of the ship's cabin. The electronic buttons include a test button, a mute button, and a dimming button, which are used for periodic testing, manual cancellation of alarms, and adjustment of indicator light brightness, respectively, thereby meeting the basic functional requirements of the alarm device.
