This causes significant difficulties in operation and management, and can easily result in unnecessary economic losses. Therefore, a new alarm mechanism is established to detect whether the quality of the connection interfaces meets standards and to promptly notify external parties. Summary of the Invention

[0021] This invention provides a power distribution cabinet line alarm mechanism with flashing lights, such as... Figure 1-4 As shown, the terminal 9 is fixed. It includes a terminal block 1, the top of which has a groove 11. A threaded post 12 is fixedly installed at the bottom of the inner wall of the groove 11. A conductive ring 2 is provided above the threaded post 12. A bolt 7 is threadedly connected to the upper end of the threaded post 12. The bolt 7 passes vertically downward through the conductive ring 2. The upper end of the bolt 7 and the conductive ring 2 are close to each other to clamp the terminal 9.
[0022] Two conductive sheets 3 are symmetrically fixedly installed on the inner wall of the groove 11. A graphene rod is fixedly installed on the upper end of the conductive sheet 3. The graphene rod has a diameter of 0.3 cm and has a certain toughness and bendability.
[0023] Two tension sensing units 4 are symmetrically fixedly installed on the inner wall of the groove 11. Each tension sensing unit 4 corresponds to a conductive sheet 3, and the tension sensing unit 4 is located directly below the conductive sheet 3. The working end of the tension sensing unit 4 faces upward and is fixedly bound with a steel wire 41. The upper end of the steel wire 41 is fixedly bound to the graphene rod. A wire is fixedly installed at the bottom of the terminal block 1. The upper end of the wire is forked and electrically connected to the lower end of the conductive sheet 3.
[0024] A flashing light is fixedly installed on the top of terminal block 1.
[0025] When not in operation, the steel wire 41 is taut. Working principle: The bolt 7 is screwed into the threaded post 12, so that the terminal 9 is stuck between the head of the bolt 7 and the conductive ring 2. During the screwing process, the conductive ring 2 slowly descends and comes into contact with the graphene rod, causing the graphene rod to deform and bend to a certain extent. At this time, the steel wire 41 becomes loose, which causes the value measured by the tension sensing unit 4 to change.
[0026] It also includes an iron ring 5, with the terminal 9 wrapped around the outside of the bolt 7. The iron ring 5 is located inside the groove 11, and the conductive ring 2 is located directly above the iron ring 5. The iron ring 5 is fitted over the threaded post 12. The bolt 7 mentioned above is a common iron metal part.
[0027] A tension sensing unit 2 6 is symmetrically fixedly installed at the bottom of the inner wall of the groove 11. A steel wire 2 61 is fixedly tied between the working end of the tension sensing unit 2 6 and the iron ring 5. A small spring 51 is welded between the bottom of the iron ring 5 and the bottom of the inner wall of the groove 11.
[0028] When not in operation, the steel wire 261 is in a slack state, and the tension sensing unit 26 measures a value of zero. Working principle: Since the terminal 9 is wound around the bolt 7, when the current passes through the terminal 9, a magnetic field is generated around the bolt 7. Under the action of the magnetism, the iron ring 5 is attracted to the bolt 7, thereby tightening the steel wire 261, and the tension sensing unit 26 measures the value.
[0029] It also includes a retaining sleeve 8, and a groove 71 is provided on the top of the bolt 7. The groove 71 is annular, and the upper end of the retaining sleeve 8 slides in the groove 71. The lower end of the retaining sleeve 8 is used to contact the conductive ring 2, and the retaining sleeve 8 surrounds the terminal 9. The retaining sleeve 8 strengthens the fixing of the terminal 9 and prevents the terminal 9 from coming off the bolt 7.
[0030] A large spring 21 is welded to the bottom of the conductive ring 2. The large spring 21 is sleeved on the outside of the threaded post 12, and the lower end of the large spring 21 is welded to the bottom of the inner wall of the groove 11. The large spring 21 has the same function as the small spring 51, which is to achieve the effect of resetting.
[0031] The conductive ring 2 and the threaded post 12 are arranged in concentric circles. The outer edge of the conductive ring 2 is in contact with the inner wall of the groove 11. The cross-section of the groove 11 is circular, and the threaded post 12 is located at the circular part of the groove 11.
[0032] It also includes a flap 10, and two support plates 13 are connected to the top of the terminal block 1. The terminal block 1 and the support plates 13 are integrally formed. One end of the flap 10 is hinged to one of the support plates 13, and the other end of the flap 10 is snapped into the other support plate 13.
[0033] A through groove 101 is provided in the center of the flip plate 10. The through groove 101 is located directly above the bolt 7. A grating 102 is symmetrically fixed on the left and right sides of the inner wall of the through groove 101. A miniature camera 103 is symmetrically fixed on the front and back sides of the inner wall of the through groove 101.
[0034] Working principle: When poor wiring contact produces an open flame, smoke is generated. The smoke drifts through the through slot 101. Due to the tiny particles in the smoke, the light emitted by the grating 102 forms a visible light path, which is captured by the miniature camera 103.
[0035] It also includes a microcontroller and a smoke alarm module. The microcontroller and the smoke alarm module are installed in the power distribution cabinet. The microcontroller, the smoke alarm module, the wires, the tension sensing unit 4, the tension sensing unit 6 and the flashing light are electrically connected.
[0036] Working principle: The tension sensor unit 4 feeds information back to the microcontroller to detect the wiring quality of terminal 9, preventing it from becoming loose due to improper wiring. The tension sensor unit 6 feeds information back to the microcontroller to detect whether the circuit is functioning properly and to detect any open circuits. The grating 102, in conjunction with the miniature camera 103, feeds information back to the microcontroller to detect the presence of open flames.
[0037] When the circuit is working properly, the flashing light will flash at a certain frequency; when the circuit is broken, the flashing light will turn off.
[0038] In summary, the alarm mechanism for the distribution cabinet with flashing lights comprises a terminal block 1, a conductive ring 2, a conductive sheet 3, a tension sensing unit 4, and a bolt 7. A retaining sleeve 8 is provided on the top of the bolt 7 to firmly fix the terminal 9 between the conductive ring 2 and the head of the bolt 7, preventing the terminal 9 from detaching from the bolt 7 and causing poor contact. The conductive sheet 3, the tension sensing unit 4, and the steel wire 41 work together to detect the tightness of the bolt 7, thereby ensuring the quality of the wiring connection at the terminal 9.
[0039] Furthermore, an iron ring 5, a tension sensing unit 6, and a steel wire 61 are installed. The wire is wound around an iron bolt 7 using a terminal 9. Current flowing through this wire generates a magnetic field, which attracts the iron ring 5, causing the tension sensing unit 6 to measure the value. This achieves the purpose of detecting whether the circuit is normal and whether there is an open circuit, ensuring the normal operation of the internal circuitry of the distribution cabinet.
[0040] Furthermore, a flip plate 10, a through slot 101, a grating 102, and a miniature camera 103 are installed. The flip plate 10 is placed above the bolt 7. The grating 102 and the miniature camera system 103 work together to detect whether the wiring terminal 9 produces an open flame, thereby improving the safety detection capability of the power distribution cabinet.
