Two first springs 45 are fixedly connected to the top end of the grounding block, and the two first springs 45 are movably sleeved on the outside of the two T-shaped rods 43 respectively. An audible and visual alarm 46 is provided between the two first springs 45. The audible and visual alarm 46 is fixedly installed at one end of the top of the power receiving block B44. A positioning frame 47 is provided between the power receiving block A42 and the circuit breaker 41. An insulating plate 48 that works with the power receiving block A42 and the power receiving block B44 is slidably connected inside the positioning frame 47. The insulating plate 48 is located between the power receiving block A42 and the power receiving block B44. The end of the insulating plate 48 away from the power receiving block B44 extends to the outside of the positioning frame 47 and is fixedly connected to a push plate 49. A push groove 50 is provided on the surface of the push plate 49. Two positioning rods 51 are provided between the circuit breaker 41 and the audible and visual alarm 46. A common pressure plate 52 is movably sleeved on the outside of the two positioning rods 51, and the pressure plate 52 is located below the circuit breaker 41. Two second springs 53 are provided below the pressure plate 52, and each second spring 53 is movably sleeved on the outside of the two positioning rods 51. A round pin 54 is slidably connected inside the push groove 50. Both ends of the round pin 54 extend to the outside of the push plate 49 and are fixedly connected to connecting plates 55. The top end of each of the two connecting plates 55 is fixedly connected to the bottom surface of the pressure plate 52. Two fixing plates 56 are provided between the push plate 49 and the circuit breaker 41, and the two fixing plates 56 are fixedly connected to the bottom surface of the inner wall of the outer casing 1. A gear is rotatably connected between the two fixing plates 56. 57. A toothed plate 58 that meshes with a gear 57 is fixedly connected to one of the connecting plates 55 near the circuit breaker 41. The toothed plate 58 and one of the connecting plates 55 are designed as a single piece. A ratchet 59 is provided on one side of the gear 57. The ratchet 59 and the gear 57 are coaxially arranged. A mounting housing 60 is provided between the ratchet 59 and the circuit breaker 41. The mounting housing 60 is fixedly connected to one of the connecting plates 55. A toothed block 61 that meshes with the ratchet 59 is slidably connected inside the mounting housing 60. A third spring 62 is fixedly connected to the side of the toothed block 61 away from the ratchet 59. The third spring 62 is located inside the mounting housing 60. An extension plate 63 is fixedly connected to one end of the top of the toothed block 61. A through groove that works with the extension plate 63 is provided at one end of the top of the mounting housing 60. A synchronous reset mechanism 7 is provided between multiple alarm mechanisms 4 and unit door 3; The synchronous reset mechanism 7 includes a reset plate 71 disposed below multiple pressure plates 52. The interior of the mounting housing 60 is provided with a positioning groove 72 that works with the reset plate 71. One end of the reset plate 71 extends to the outside of the housing 1 and is fixedly connected with a threaded block 73. A threaded rod 74 is rotatably connected to one side of the housing 1 via a U-shaped frame plate. A contact plate 75 is disposed on the side of multiple extension plates 63 away from the circuit breaker 41, and the contact plate 75 is slidably connected in a groove reserved inside the housing 1. A contact rod 76 is disposed between multiple alarm mechanisms 4, and the contact rod 76 is fixedly connected to the contact plate 75. Multiple unlocking plates 77 that work with the contact rod 76 are fixedly connected to one bottom end of the reset plate 71, and the unlocking plate 77 and the contact rod 76 are configured in a one-to-one correspondence. The T-shaped rod 43 consists of a round rod and a disc at one end of the top of the round rod. The first spring 45 is located between the contact block B44 and the disc in the T-shaped rod 43. The positioning rod 51 consists of two round rods with different diameters and a disc. The round rod with the larger diameter is fixedly connected to the bottom surface of the inner wall of the outer casing 1. The opposite sides of the contact block A42 and the contact block B44 are both set as arcs. The side cross-section of the insulating plate 48 away from the push plate 49 is conical. The threaded block 73 consists of a baffle for blocking the positioning groove 72 and a connecting block with a threaded hole on the side of the baffle away from the reset plate 71. The baffle in the threaded block 73 is located inside the U-shaped frame plate. The unlocking plate 77 consists of a plate with a groove. Before using this device, connect the circuit breaker 41 to the corresponding electromechanical control equipment electrically; During use, when the corresponding electromechanical control equipment experiences a circuit current overload due to a fault, the corresponding circuit breaker 41 automatically cuts off the circuit, and the switch of circuit breaker 41 automatically closes. At this time, the switch pushes the pressure plate 52 to move down synchronously, causing the pressure plate 52 to slide down outside the two positioning rods 51 and squeeze the second spring 53. This causes the pressure plate 52 to push the toothed plate 58 down synchronously through the two connecting plates 55. During the downward movement, the meshing action between the toothed plate 58 and the gear 57 drives the coaxial ratchet 59 to rotate counterclockwise. Due to the toothed block 61 that works with the ratchet 59... The ratchet 59 is restricted to rotating clockwise. Therefore, the ratchet 59 can rotate counterclockwise with the cooperation of the structure. During the rotation of the ratchet 59, the tooth block 61 slides on the surface of the ratchet 59 and squeezes the third spring 62. When the pressure plate 52 stops moving down, the ratchet 59 stops rotating with the cooperation of the structure. At this time, the tooth block 61 engages with the ratchet 59 under the extension and reset action of the third spring 62, restricting and fixing the ratchet 59 to prevent the ratchet 59 from rotating in the opposite direction, causing the circuit breaker 41 to switch on the pressure plate 52, resulting in unstable use of the circuit breaker. When the pressure plate 52 moves down, the two connecting plates 55 drive the round pin 54 to move down synchronously inside the push groove 50, and push the push plate 49 to move closer to the circuit breaker 41 through the push groove 50. This causes the push plate 49 to drive the insulating plate 48 to move synchronously, pulling the insulating plate 48 out from between the contact block A42 and the contact block B44. This allows the contact block B44 to move down along the two T-shaped rods 43 under the extension and reset action of the two first springs 45, so that the contact block B44 contacts the contact block A42. This then powers on the audible and visual alarm 46 to sound an alarm and notify the staff to inspect the electromechanical control equipment corresponding to the circuit breaker 41. After the above maintenance is completed, the operator can directly rotate the threaded rod 74, causing it to rotate inside the threaded block 73. This causes the threaded block 73 to move the reset plate 71 upward inside the positioning groove 72. The reset plate 71 then moves the unlocking plate 77 upward synchronously. Simultaneously, the unlocking plate 77 moves upward with the reset plate, and through its contact with the abutment rod 76, the abutment rod 76 pushes the abutment plate 75 away from the cover 2. This causes the abutment plate 75 to push multiple extension plates 63 to move synchronously, causing the extension plates 63 to move the toothed block 61 into the mounting housing 60 and compress the third spring 62. This releases the restrictive and fixing effect of the toothed block 61 on the ratchet 59. Then, as the reset plate 71 continues to move upward, it pushes the multiple pressure plates 52 upward and resets them through the contact between the multiple pressure plates 52 and the closed circuit breaker 41 switch. This allows the multiple pressure plates 52 to push the multiple circuit breaker 41 switches to open through the contact between the closed circuit breaker 41 switches, thus completing the synchronous opening of multiple circuit breakers 41 in one operation. When the reset plate 71 is moved to the top of the positioning groove 72 and cannot be moved further due to the cooperation between the above structures, the threaded rod 74 can be rotated in the opposite direction. Through the cooperation between the threaded rod 74 and the above structures, the reset plate 71 can be driven to move downward and reset. When the pressure plate 52 moves upward and resets, the pressure plate 52 drives the round pin 54 to move upward synchronously through the connecting plate 55, so that the round pin 54 moves in the opposite direction inside the push groove 50 and drives the push plate 49 to move closer to the cover 2, so that the push plate 49 pushes the insulating plate 48 to move between the electrical block A42 and the electrical block B44, thereby using the insulating plate 48 to separate the electrical block A42 and the electrical block B44 again, that is, to turn off the audible and visual alarm 46; By incorporating an alarm mechanism 4 and a synchronous reset mechanism 7, this invention not only enables automatic location and alarm for damaged electromechanical control equipment, improving the efficiency of electromechanical control equipment maintenance, but also avoids the waste of resources caused by the alarm remaining constantly lit. Furthermore, a single operation can simultaneously open multiple closed circuit breakers 41 after the maintenance of the electromechanical control equipment, further improving the efficiency of electromechanical control equipment maintenance and increasing the practicality of the electromechanical control equipment fault location alarm device.

[0018] like Figures 1 to 9 As shown, the interior of the outer casing 1 is provided with multiple automatic door opening mechanisms 8, and the multiple automatic door opening mechanisms 8 are configured in a one-to-one correspondence with multiple unit doors 3; The automatic door opening mechanism 8 includes a guide plate 81 fixedly connected to the side of the cover 2 near the circuit breaker 41, and the guide plate 81 is positioned above the unit door 3. A square rod 82 is slidably connected inside the guide plate 81, and a square anti-detachment plate is provided at the top end of the square rod 82. A door opening plate 83 with a horizontal groove is fixedly connected to the bottom end of the square rod 82. A fourth spring 91 is provided between the door opening plate 83 and the guide plate 81, and the fourth spring 91 is movably sleeved on the outside of the square rod 82. A pin 84 is slidably connected inside the horizontal groove of the door opening plate 83. Both ends of the pin 84 extend to the outside of the door opening plate 83 and are fixedly connected to fixing rods 85. The ends of the two fixing rods 85 away from the pin 84 are both connected to the top of the unit door 3. The unit door 3 is fixedly connected to the bottom of the unit door 3. A rotating rod 86 is provided below the unit door 3. The rotating rod 86 is rotatably connected to the reserved hole on the bottom side of the outer shell 1. One end of the rotating rod 86 extends to the outside of the outer shell 1 and is fixedly connected to a locking block 87 that works with the unit door 3. A slot is opened at the bottom of the outer shell 1. The end of the rotating rod 86 away from the locking block 87 extends into the slot and is fixedly sleeved with a lever 88. A torsion spring 89 is fixedly connected to the side of the lever 88 away from the locking block 87. The side of the torsion spring 89 away from the locking block 87 is fixedly connected to the inner wall of the slot, and the torsion spring 89 is movably sleeved on the outside of the rotating rod 86. A pressure rod 90 that works with the lever 88 is fixedly connected to the bottom of each of the multiple pressure plates 52. The locking block 87 consists of a disc and a protrusion disposed on the outside of the disc, and the locking block 87 is disposed on the side of the unit door 3 away from the outer shell 1. The toggle block 88 consists of a ring and a protrusion disposed on the outside of the ring. After connecting multiple circuit breakers 41 to corresponding electromechanical control equipment, the rotating rod 86 can be rotated by the locking block 87, so that the rotating rod 86 drives the torsion spring 89 and the lever 88 to store force. Then the unit door 3 is closed, so that the unit door 3 drives the pin 84 to rotate synchronously through the two fixed rods 85, so that the pin 84 slides inside the horizontal groove in the opening plate 83 and drives the opening plate 83 to move upward. Thus, the opening plate 83 drives the square rod 82 to move upward synchronously and squeeze the fourth spring 91. When the unit door 3 is attached to the outer shell 1, the locking block 87 is released, so that the rotating rod 86 drives the locking block 87 to rotate in the opposite direction under the reset action of the torsion spring 89, so that the locking block 87 jams the unit door 3, thereby locking the unit door 3. When the aforementioned pressure plate 52 activates the audible and visual alarm 46 through the cooperation between the structures, the pressure plate 52 pushes the pressure rod 90 to move down synchronously. When the pressure rod 90 moves down to contact the protruding plate in the toggle block 88, the pressure rod 90 pushes the toggle block 88 to rotate, causing the toggle block 88 to drive the rotating rod 86 to rotate synchronously and drive the torsion spring 89 to store force, so that the rotating rod 86 drives the locking block 87 to rotate synchronously and release the locking effect on the unit door 3. At this time, the opening plate 83 drives the square rod 82 to move down under the extension and reset action of the fourth spring 91, so that the opening plate 83 drives the unit door 3 to rotate clockwise and open through the pin 84 and the two fixed rods 85, so that the corresponding unit door 3 is opened. The present invention, by providing an automatic door opening mechanism 8, can open the corresponding unit door 3 when the corresponding audible and visual alarm 46 is activated. This not only prevents the unit door 3 from blocking the light and sound of the audible and visual alarm 46, but also reduces the steps required to open the circuit breaker 41 after maintenance. This further reduces the steps required to maintain electromechanical control equipment, improves maintenance efficiency, and increases the overall practicality of the electromechanical control equipment fault location alarm device. Example 2:

[0019] The present invention also provides a location alarm method for a fault location alarm device for electromechanical control equipment, comprising the following steps: S1: Separate the cap 2 from the outer casing 1; S2: Connect the circuit breaker 41 to the corresponding electromechanical control equipment via electrical connection; S3: Use screws to connect the cover 2 to the outer casing 1; S4: When the corresponding electromechanical control equipment experiences a circuit current overload due to a fault, the corresponding circuit breaker 41 automatically cuts off the circuit, the switch of circuit breaker 41 automatically closes, and the audible and visual alarm 46 is activated through the cooperation between the structures in the alarm mechanism 4. S5: The maintenance personnel locate the corresponding electromechanical control equipment through the corresponding audible and visual alarm 46, perform maintenance on the electromechanical control equipment, and at the same time use the automatic door opening mechanism 8 to open the corresponding unit door 3. S6: Using the synchronous reset mechanism 7, multiple closed circuit breakers 41 are opened simultaneously, and the locking unit door 3 is closed.
