Technical Field

[0001] This invention relates to the field of fire monitoring and detection devices, and in particular to an electrical fire monitoring and detection device and system for detecting insulation performance. Background Technology

[0002] Electrical fires have long been one of the major types of fires that seriously threaten public safety. Electrical fire monitoring and detection devices and systems that detect insulation performance represent the most cutting-edge technology for addressing this type of hazard. By monitoring the insulation resistance value of power supply lines in real time and online, they can issue early warnings when the insulation layer's performance deteriorates due to aging, wear, moisture, or other reasons.

[0003] External wiring typically uses traditional screw-on terminals for installation on monitoring terminals. This requires tools to tighten the screws, making the process extremely inconvenient and inefficient. Furthermore, wiring quality heavily relies on the installer's skill level; insufficient tightening force can lead to poor contact and overheating, while excessive force can damage the wire core, posing a reliability risk to the system. Therefore, there is an urgent need for an electrical fire monitoring and detection device and system that facilitates wiring and detects insulation performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrical fire monitoring and detection device and system that detects insulation performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electrical fire monitoring and detection device for detecting insulation performance includes a monitoring terminal. A terminal block is fixedly installed on the top of the monitoring terminal. The terminal block has multiple interfaces, and the connecting wires are all adapted to be inserted into the interfaces. The mounting posts are all fixedly mounted on the terminal block and located on the outside of the interface. Mounting rings are fixedly provided on the connecting lines, and each mounting ring has multiple mounting cavities, which are adapted to the mounting posts. The retaining ring is sleeved on the outside of the connecting line and rotates. Each retaining ring on the mounting post has a matching retaining cavity, and each retaining ring on the mounting post has a matching reset cavity. The movable rings are all spring-loaded and move on the connecting line, and the movable rings and retaining rings are locked together by static friction and magnetic force generated by contact.

[0006] Furthermore, in a preferred configuration, all mounting posts are fixedly mounted on the terminal block, and the mounting posts are arranged in a ring array around the interface.

[0007] Furthermore, in a preferred configuration, each mounting post has a retaining cavity, and each retaining cavity is adapted to a retaining ring.

[0008] Furthermore, in a preferred configuration, each retaining ring is provided with a reset cavity, and when the reset cavity rotates to align with the retaining cavity, the mutual locking between the retaining cavity and the retaining ring is released.

[0009] In addition, a preferred structure is that multiple guide arc members are fixedly provided on the inner wall of the retaining ring, and multiple guide arc grooves are opened on the connecting line, and the guide arc members are all adapted to the guide arc grooves.

[0010] In addition, a preferred structure is that a fixing seat is installed on both sides of the connecting line, and a guide cavity is opened on each fixing seat.

[0011] In addition, a preferred structure is that multiple guide posts are fixedly installed on each of the movable rings, and each guide post passes through the guide cavity and is fixedly equipped with an anti-detachment component.

[0012] In addition, a preferred structure is that the movable ring and the fixed base are connected by multiple springs, and each movable ring has a through hole, which is adapted to the mounting post.

[0013] An electrical fire monitoring and detection system based on insulation performance includes a monitoring terminal. The terminal block is connected to a temperature sensor and a residual current sensor via connecting wires, and the monitoring terminal is equipped with an audible and visual alarm. The monitoring terminal is equipped with an intelligent data gateway. The data generated by the monitoring terminal is transmitted to the data storage unit and the user terminal through the intelligent data gateway. The data storage unit is equipped with an AI big data analysis unit. The predicted data generated by the AI ​​big data analysis unit is directly transmitted to the local database in the user terminal and the monitoring terminal.

[0014] The beneficial effects of this invention are as follows: through the adaptive arrangement of the terminal block, mounting post, retaining ring, movable ring and spring, quick plugging and locking between the connecting wire and the interface can be achieved, and the installation of the connecting wire can be completed without tools, which improves the efficiency of construction and maintenance. In addition, this structure avoids poor contact or wire core damage caused by loose screws, which improves the stability and safety of electrical connection. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-8 An electrical fire monitoring and detection device for detecting insulation performance includes a monitoring terminal 1. A terminal block 11 is fixedly installed on the top of the monitoring terminal 1. The terminal block 11 has multiple interfaces 12, and the connecting wires 3 are all adapted to be inserted into the interfaces 12.

[0019] The mounting posts 2 are all fixedly mounted on the terminal block 11 and located outside the interface 12. The connecting wires 3 are all fixedly provided with mounting rings 31, and the mounting rings 31 are all provided with multiple mounting cavities 311, and the mounting cavities 311 are all adapted to the mounting posts 2.

[0020] The retaining ring 4 is sleeved on the outside of the connecting line 3 and rotates. The mounting post 2 is provided with a matching retaining cavity 21 corresponding to the retaining ring 4, and the retaining ring 4 is provided with a matching reset cavity 41 corresponding to the mounting post 2.

[0021] The movable rings 5 ​​are all mounted on the connecting line 3 by springs 6, and the movable rings 5 ​​and the retaining rings 4 are locked together by static friction and magnetic force generated by contact.

[0022] All mounting posts 2 are fixedly mounted on the terminal block 11, and are arranged in a ring array around the interface 12. Each mounting post 2 has a locking cavity 21, and each locking cavity 21 is adapted to the locking ring 4. Through the adaptation and locking between the locking cavity 21 and the locking ring 4, the adaptation and locking between the connecting wire 3 and the interface 12 can be achieved.

[0023] Each retaining ring 4 has a reset cavity 41. When the reset cavity 41 rotates to align with the retaining cavity 21, the mutual locking between the retaining cavity 21 and the retaining ring 4 is released.

[0024] The retaining ring 4 has multiple guide arc elements 42 fixedly installed on its inner wall, and multiple guide arc grooves 32 are opened on the connecting line 3, with the guide arc elements 42 all fitting into the guide arc grooves 32. Through the fitting arrangement between the guide arc elements 42 and the guide arc grooves 32, not only can the retaining ring 4 be guided to rotate, but the rotation angle of the retaining ring 4 can also be limited.

[0025] The connecting line 3 has a fixing seat 33 installed on both sides, and each fixing seat 33 has a guide cavity 331. Multiple guide posts 52 are fixedly installed on the movable ring 5, and each guide post 52 passes through the guide cavity 331 and is fixedly equipped with an anti-detachment component 521. Through the adaptive arrangement between the guide cavity 331 and the guide post 52, the movable ring 5 can be guided and moved, thereby improving the stability of the movable ring 5 during movement.

[0026] The movable ring 5 and the fixed base 33 are connected by multiple springs 6. Each movable ring 5 has a through hole 51, and each through hole 51 is adapted to the mounting post 2. The springs 6 can push the movable ring 5 to ensure tight contact between the movable ring 5 and the retaining ring 4.

[0027] Both sides of the movable ring 5 are provided with sub-magnetic components, and both sides of the retaining ring 4 are provided with female magnetic components. The sub-magnetic components and female magnetic components are mutually compatible and repulsive, so that the retaining ring 4 can be rotated to the angle where it can be locked through magnetic attraction. Furthermore, the contact surfaces of the movable ring 5 and the retaining ring 4 are covered with rough friction pads to further prevent the retaining ring 4 from rotating, thereby improving the stability of the retaining ring 4 when locked.

[0028] The electrical fire monitoring and detection system, which detects insulation performance, includes a monitoring terminal. The terminal's junction box is connected to a temperature sensor and a residual current sensor via connecting cables, and the monitoring terminal is equipped with an audible and visual alarm. The monitoring terminal is equipped with an intelligent data gateway. Data generated by the monitoring terminal is transmitted through the intelligent data gateway to a data storage unit and a user terminal. The data storage unit contains an AI big data analysis unit, and the predicted data generated by the AI ​​big data analysis unit is directly transmitted to the local databases in both the user terminal and the monitoring terminal.

[0029] In this embodiment, during operation, the monitoring terminal located at the front end collects key data of the electrical circuit in real time by connecting a temperature sensor and a residual current sensor.

[0030] The collected data is uploaded to the cloud via an intelligent data gateway. The core processing hub is the cloud-based data storage unit, which integrates an AI big data analytics unit. This AI unit performs deep learning and trend analysis on massive amounts of historical and real-time data to generate predictive early warning information. These intelligent analysis results are simultaneously distributed to user terminals (such as mobile phones and computers) and the local database of the monitoring terminal, achieving an optimized upgrade of remote mobile early warning and local judgment capabilities.

[0031] Furthermore, during the wiring process, simply rotate the retaining ring 4 to one side, at which point the reset cavity 41 on the retaining ring 4 and the retaining cavity 21 on the mounting post 2 will be properly aligned. Then, simply insert the connecting wire 3 directly into the interface 12, at which point the retaining ring 4 will automatically enter the retaining cavity 21 on the mounting post 2, and the mounting posts 2 will all be inserted into the mounting cavities 311.

[0032] The user then simply needs to release the retaining ring 4 and pull the movable ring 5 outward. At this point, all springs 6 are compressed, and there is no longer static friction between the retaining ring 4 and the movable ring 5. The retaining ring 4 can then rotate automatically by magnetic force. At this point, the reset cavity 41 on the retaining ring 4 is no longer aligned with the retaining cavity 21, and the retaining ring 4 can automatically lock into the retaining cavity 21.

[0033] Finally, the user only needs to loosen the movable ring 5, and the movable ring 5 will automatically reset due to the elastic force of the spring 6. At this time, the movable ring 5 will once again contact and lock with the retaining ring 4, thereby achieving the fixed locking of the retaining ring 4 and realizing the fixed installation of the connecting wire 3.

[0034] Furthermore, when the user needs to remove the connecting wire 3, simply pull the movable ring 5 outward to release the contact lock between the movable ring 5 and the retaining ring 4. Then rotate the retaining ring 4 again to align the reset cavity 41 on the retaining ring 4 with the retaining cavity 21, at which point the connecting wire 3 can be pulled out directly.

[0035] Furthermore, both sides of the movable ring 5 are provided with sub-magnetic components, and both sides of the retaining ring 4 are provided with female magnetic components. The sub-magnetic components and female magnetic components are mutually compatible and repulsive, so that the retaining ring 4 can be rotated to the angle where it can be locked through magnetic attraction. In addition, the contact surfaces of the movable ring 5 and the retaining ring 4 are covered with rough friction pads to further prevent the retaining ring 4 from rotating, thereby improving the stability of the retaining ring 4 when locked.

[0036] In this invention, the fitting arrangement between the terminal block 11, mounting post 2, retaining ring 4, movable ring 5 and spring 6 enables quick plugging and locking of the connecting wire 3 and the interface 12. The installation of the connecting wire 3 can be completed without tools, improving construction and maintenance efficiency. Furthermore, this structure avoids poor contact or wire core damage caused by loose screws, improving the stability and safety of the electrical connection.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
