Description

Technical Field

[0001] The utility model relates to the field of fire monitoring of a plug-in box, and more specifically, to a fire early warning monitoring device for a low-voltage bus duct plug-in box. Background Art

[0002] A low-voltage busbar plug-in box is an electrical device used in low-voltage power distribution systems. It is primarily used in conjunction with busbars, a highly efficient electrical energy transmission device capable of carrying high currents. As a key branch unit of the busbar, the plug-in box extracts power from the busbar. It connects tightly to the busbar via a plug-in connection, a convenient and fast method that ensures good electrical contact, reduces contact resistance, and minimizes energy loss and heat generation.

[0003] The busbar duct plug-in box is a key component in low-voltage power distribution systems. It draws power from the busbar duct to numerous electrical devices. During operation, current flows through the box. When overloads, short circuits, or poor contact occur, electrical components and connections generate significant heat. If this heat is not detected and addressed promptly, it can easily cause a fire. Furthermore, the plug-in box contains electrical components such as circuit breakers and fuses, as well as numerous wiring connection points. After prolonged use, these components may malfunction due to aging and wear, generating sparks or localized overheating, which can easily lead to fires.

[0004] Existing fire warning monitoring devices for low-voltage busbar duct plug-in boxes have numerous problems. For one thing, their position cannot be adjusted, which greatly complicates the installation of other components on the plug-in box. Because the internal space of a plug-in box is typically limited, the layout of each component requires careful planning. Fixed-position fire warning monitoring devices may occupy key installation locations, making it difficult for other necessary components to find suitable installation space, impacting the overall installation efficiency and layout rationality of the plug-in box. On the other hand, existing fire warning monitoring devices typically only have basic temperature detection capabilities. Relying solely on temperature detection (monitoring temperature) makes it difficult to fully and accurately determine fire risks, delaying the optimal fire extinguishing opportunity, increasing the risk of fire spread, and posing a serious threat to the safety of personnel and equipment.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a fire early warning monitoring device for a low-voltage bus duct junction box. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a fire alarm monitoring device for a low-voltage bus duct junction box.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a low-voltage bus duct plug-in box fire early warning monitoring device, comprising a low-voltage bus duct and a plug-in box arranged on the top of the low-voltage bus duct, wherein a monitoring device body for monitoring the electrical components inside the low-voltage bus duct is installed inside the plug-in box, and an adjustment component is also installed inside the low-voltage bus duct to adjust the position of the monitoring device body within the plug-in box, and the monitoring device body comprises:

[0008] A power module is used to supply power to other components on the main body of the monitoring device;

[0009] The main control module has a sensor connected to the electrical components in the plug-in box through a signal line. The sensor detects various data of the electrical components in the plug-in box and sends a signal to the LOAR wireless transmission module when the data reaches a critical point;

[0010] The LOAR wireless transmission module transmits relevant alarm information to the monitoring software background for real-time display based on the signal sent by the main control module.

[0011] Preferably, the sensors of the main control module include a temperature sensor, a current sensor, a voltage sensor and an AC leakage current sensor.

[0012] Preferably, an antenna extending from the top of the plug-in box is installed on the top of the LOAR wireless transmission module.

[0013] Preferably, the adjustment assembly includes a sliding rod fixed in the plug-in box, a sliding sleeve is slidably connected to the outer wall of the sliding rod, the monitoring device body is fixed on the surface of the sliding sleeve, the top of the sliding rod is provided with screw holes arranged in a horizontal array, the top of the sliding sleeve is provided with a through hole, a screw is installed above the through hole, and the screw is sequentially passed through the through hole downward and then rotated clockwise to be installed in the screw hole.

[0014] Preferably, a long through slot A for the antenna to move is provided on the top of the low-voltage bus duct, so as to prevent the outer shell of the plug-in box from obstructing the movement of the antenna.

[0015] Preferably, a long through slot B is provided on the surface of the plug-in box, and the portion where the screw hole is provided on the slide rod and the through hole is provided on the slide sleeve extends from the long through slot B. The outer surface of the plug-in box fixes the slide rod through an N-shaped connecting plate to facilitate adjustment operations by staff.

[0016] Preferably, each sensor on the main control module is individually mounted on the main control module by screws. When a single sensor is damaged, it can be individually disassembled and replaced without affecting the use of other sensors.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the position of the monitoring device is found to be inappropriate, the present invention can adjust its position through the adjustment component, thereby solving the problem in the background art that the position of the monitoring device cannot be adjusted, which brings great difficulties to the installation of other components on the plug-in box;

[0019] 2. The utility model uses a power supply module to power other devices on the monitoring device body, connects the sensors on the main control module with the electrical components in the plug-in box through signal lines, and detects various data of the electrical components in the plug-in box through the sensors. It should be noted that the sensors include temperature sensors, current sensors, voltage sensors, AC leakage current sensors, etc., which can stably detect various data such as temperature, current, voltage and AC leakage current, and the detection is more comprehensive. When the data critical point is reached, the main control module will send a signal to the LOAR wireless transmission module. The LOAR wireless transmission module transmits the relevant alarm information to the monitoring software background for real-time display based on the signal sent by the main control module, thereby achieving the purpose of early warning and monitoring. Compared with the separate temperature monitoring in the prior art, its monitoring is more comprehensive, thereby better preventing fires, so as to solve the problem that the existing fire early warning monitoring device in the background technology usually only has a basic temperature detection function, and it is difficult to comprehensively and accurately judge the fire risk by relying solely on temperature detection;

[0020] 3. The LOAR wireless transmission module of this utility model is equipped with an antenna extending from the top of the plug-in box. The antenna can effectively transmit the signal in the form of electromagnetic waves to a distant location. The appropriate antenna can enhance the signal strength and make the signal propagate further, which is more conducive to the LOAR wireless transmission module to send the alarm information.
