Description

Technical Field

[0001] This utility model relates to the field of electrical equipment monitoring technology, specifically to an electrical fire monitoring and control device that integrates multiple sensors. Background Technology

[0002] An electrical fire monitoring system is a fire protection system specifically designed to monitor and control electrical fires. Its key feature is the monitoring of electrical equipment and wiring for leaks, short circuits, and other hazards, thus preventing fires from occurring. It is an early warning system used to monitor the safety of electrical equipment and wiring. It can promptly detect and warn of potential fire risks, providing crucial protection for the safety of electrical equipment and personnel.

[0003] In the prior art, a patent publication number (CN220983988U) describes an electrical fire monitoring device, which includes a mounting box screwed onto a wall and a detector; two clamping mechanisms, each of which includes a rotating rod rotatably connected inside the mounting box, with a clamping plate fixedly connected to the rotating rod. One end of the clamping plate abuts against the top of the detector, and the other end is equipped with a first spring, enabling the detector to be quickly removed, thus improving maintenance efficiency. However, traditional monitoring devices typically fix the sensors inside electrical cabinets or simply hang them externally, making their positions non-adjustable and difficult to accurately control cables or electrical connection points of different specifications and heating characteristics. Furthermore, existing devices often rely on single or a few sensors (such as only temperature or only residual current), lacking the ability to synchronously and fusedly analyze multiple parameters such as temperature, arc, current, and leakage current. This makes it impossible to achieve comprehensive and three-dimensional perception of electrical fire hazards, easily leading to missed or false alarms, thereby reducing the effectiveness of fire monitoring.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a multi-sensor fusion electrical fire monitoring and control device includes a base plate 1, an electrical cabinet 2 fixed to the top of the base plate 1, electrical components 3 fixed to both the left and right sides inside the electrical cabinet 2, a protective outer plate 4 fixed to the front of the electrical cabinet 2 by bolts, and partitions 5 separating the electrical components 3 on both sides. A clamping assembly is provided on the left side of the electrical cabinet 2, the clamping assembly including two outer plates 6, which are respectively fixed to the front and rear ends of the left side of the electrical cabinet 2, and telescopic rods 7 are fixed to the inner sides of the two outer plates 6. The two telescopic rods 7 are arranged in a mirror image along the center, and clamping plates 8 are fixed to the telescopic ends of the two telescopic rods 7. The outer perimeter of the clamping plates 8 is smooth. A controller 9 is fixed to the upper right side of the electrical cabinet 2. In the prior art, traditional monitoring devices... Sensors are typically fixed inside the electrical cabinet 2 or simply mounted externally, and their positions are not adjustable. This makes it difficult to accurately deploy sensors for cables or electrical connection points of different specifications and heating characteristics. In addition, existing devices often rely on a single or a few sensors (such as only temperature or only residual current), lacking the ability to synchronously and fusedly analyze multiple parameters such as temperature, arc, current, and leakage current. This makes it impossible to achieve comprehensive and three-dimensional perception of electrical fire hazards, which can easily lead to missed or false alarms, thereby reducing the effectiveness of fire monitoring. To address these issues, a mirror telescopic clamping assembly can be installed outside the electrical cabinet 2. This provides an adjustable and secure clamping point for power lines, communication lines, or sensor cables introduced into the cabinet, improving the applicability of the equipment in different field environments and its overall aesthetics.

[0022] A sensor assembly is provided between the two clamping plates 8. The sensor assembly includes multiple plates 10, which are all fixed to the outside left side of the electrical cabinet 2 by bolts. Sensor bodies 11 are fixed to the outside of the plates 10. The multiple sensor bodies 11 are electrically connected to the controller 9. Adjacent plates 10 are embedded and connected by support plates 12. The multiple sensor bodies 11 are integrated into one area through the plates 10 to form a unified sensor array, which provides a physical basis for realizing true "multi-sensor fusion" monitoring.

[0023] A motor 13 is fixed to the front right side of the electrical cabinet 2. The output end of the motor 13 extends through to the inside of the electrical cabinet 2 and is fixed to a rotating plate 14 via a coupling. Blades 15 are provided on the outside of the rotating plate 14 to effectively prevent heat accumulation by forcibly creating airflow.

[0024] Multiple placement slots 16 are provided on both the left and right sides of the electrical cabinet 2. Each placement slot 16 has a ventilation plate 17 fixed inside. Each ventilation plate 17 has ventilation holes 18 on its outer side. This not only ensures smooth airflow to achieve efficient heat exchange, but also forms a physical barrier inside the cabinet, which serves to prevent dust and foreign objects from entering.

[0025] The top of the electrical cabinet 2 is fixed with a top plate 19. Warning lights 20 are fixed at the center of the left and right sides of the top of the top plate 19. The warning lights 20 are electrically connected to the controller 9 to ensure that the alarm signal is not blocked and can be detected in time by people in different directions and at a distance.

[0026] The rotating plate 14 and the blade 15 are connected by a threaded connection through a shock-absorbing rubber block 21, which effectively isolates and absorbs vibration energy, prevents vibration from being directly transmitted to the bearings of the rotating plate 14 and the motor 13, and reduces losses.

[0027] Multiple airflow holes 22 are perforated on the outside of the partition 5. All airflow holes 22 are square-shaped, allowing air to circulate between the two separated cavities. Together with the active heat dissipation system, they form a unified air duct that runs through the entire cabinet.

[0028] Working Principle: After the device is powered on, the sensor assembly fixed on the left side of the electrical cabinet 2 begins to work. Multiple sensor bodies 11 (which can integrate temperature, residual current, fault arc, etc. sensors) monitor the cables entering the electrical cabinet 2 and the environment inside the cabinet in real time with multiple parameters. The monitoring data is transmitted to the controller 9 in real time via electrical signals. When a slight increase in current is detected, if it is not accompanied by a temperature increase, it may be judged as normal load fluctuation. If both an overcurrent and a sharp temperature increase are detected at the same time, it is judged as a high risk of "overload heating". If the current waveform unique to fault arc is detected, it is immediately judged as an emergency. Once the controller 9 determines that the risk level exceeds the preset threshold, it will immediately activate the response audible and visual alarm. The controller 9 drives the warning light 20 on the top to emit a flashing red light and a high-frequency sound, realizing a long-distance, multi-directional visual and audible alarm. The controller 9 can also send a trip command to the associated circuit breaker to cut off the power supply to the dangerous area. To prevent heat buildup inside the cabinet, the controller 9 can start the motor 13 at regular intervals or based on data from the internal temperature sensor, driving the rotating plate 14 and blades 15 to rotate. This draws in cool external air from the ventilation plate 17 on one side. The airflow passes through the airflow holes 22 on the partition 5, dissipating heat evenly throughout the entire cabinet space before being discharged from the ventilation plate 17 on the other side, forming an effective airflow channel. When the cooling system is working, the shock-absorbing rubber block 21 between the rotating plate 14 and blades 15 effectively absorbs vibration, ensuring stable, low-noise, and long-life operation of the cooling system. For various cables introduced into the electrical cabinet 2, the two clamping plates 8 of the clamping assembly can be firmly clamped by the telescopic movement of the telescopic rod 7, preventing connection failures or monitoring point displacement caused by loose or pulled cables, thus ensuring continuous and reliable monitoring. If a sensor body 11 needs to be replaced, only the corresponding mounting plate 10 needs to be removed. The modular design makes maintenance quick and easy without affecting the normal operation of other sensors.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
