[0030] The present application provides a low-voltage power outage monitoring device, as shown in Figures 1-5, a fixing seat 1, a wiring port 113 is opened on the side wall of the fixing seat 1, a limited fixing column 2 is fixedly installed on the bottom of the fixing seat 1, a main frame 3 is fixedly installed on the bottom of the limited fixing column 2, a protective cover 4 is fixedly installed on the bottom of the main frame 3, a magnetic core coil 5 is fixedly installed inside the limited fixing column 2, a movable column 6 is provided at the bottom of the magnetic core coil 5, a limited cover 7 is provided at the bottom of the movable column 6, a lighting structure is provided inside the protective cover 4, a battery 61 is provided on one side of the movable column 6, the battery 61 is fixedly installed with the inside of the limited cover 7, and a contact copper is fixedly installed on the bottom of the limited cover 7. Piece 16, the top of the limit cover 7 is fixedly connected to the limit ring 8, an alarm device is provided on one side of the main frame 3 and inside the limit cover 7, a groove 71 is provided on the top of the limit cover 7, a motor 9 is fixedly installed inside the groove 71, and an extrusion device 10 is provided on one side of the motor 9, a first clamping block 11 is fixedly installed on the top of the motor 9 and inside the groove 71, a limit block 12 is provided inside the first clamping block 11, and a second clamping block 13 is provided on the top of the limit block 12, a connecting rod 14 is fixedly connected to the outer surface of one side of the limit block 12, a fixing ring 15 is fixedly connected to the outer surface of the movable column 6.

[0031] The fixing base 1 is fixed to the wall by screws, and the device is powered on by connecting the power supply. At this time, the magnetic core coil 5 generates a magnetic field, causing the movable column 6 to move upward, driving the limit ring 8 and the connecting rod 14 to move upward, causing the limit block 12 to move toward the top of the first clamping block 11, so that the top of the limit block 12 moves to the inside of the second clamping block 13. By starting the motor 9, the extrusion device 10 moves to the inside of the second clamping block 13, thereby fixing the limit block 12 from both sides, so that when the movable column 6 is attracted by the magnetic core coil 5, it remains stable, preventing external impact from causing the movable column 6 and the magnetic core coil 5 to move, resulting in poor contact and causing the alarm device to generate a false alarm. When the line is powered off, the magnetic core coil 5 no longer generates a magnetic field, and then the movable column 6 will not be attracted, driving the limit block 12 to move downward, so that the movable column 6 is no longer fixed, and the bottom of the movable column 6 is inserted into the middle of the contact copper sheet 16. Then the power in the battery 61 will pass through the contact copper sheet 16 to energize the alarm device, and then sound an alarm, allowing the user to be informed.

[0032] As shown in Figures 4-5, the extrusion device 10 includes a reverse double-threaded rod 101, the first end of the reverse double-threaded rod 101 is fixedly connected to the output shaft of the motor 9, and the second end thereof is rotatably connected to the inner wall of the groove 71, the outer surface of the reverse double-threaded rod 101 is fixedly sleeved with a movable block 102, the top of the movable block 102 is fixedly connected to a support rod 103, a movable groove 72 is provided at the top of the groove 71, the support rod 103 is movably connected to the inside of the movable groove 72, and the top of the support rod 103 is fixedly connected to an extrusion block 104.

[0033] The motor 9 drives the reverse double-threaded rod 101 to rotate, so that the movable block 102 sleeved on the reverse double-threaded rod 101 drives the support rods 103 to approach each other, so that the extrusion blocks 104 approach each other. When the support rods 103 move to the outer walls of the first block 11 and the second block 13, and the extrusion block 104 moves to the inside of the second block 13, the motor 9 is stopped, so that the extrusion block 104 fixes the limit block 12 from both sides of the limit block 12, keeping the limit block 12 stable, thereby keeping the movable column 6 stable and facilitating adsorption with the magnetic core coil 5.

[0034] As shown in Figure 3-6, the front and rear sides of the first clamping block 11 are provided with a sliding groove 111, the top of the limit block 12 is provided with a limiting device, the bottom end of the limit block 12 is fixedly connected with a protrusion 121, and the protrusion 121 is slidably connected to the sliding groove 111. A strip groove 112 is provided on the outer surface of the side of the first clamping block 11 close to the movable column 6, and a movable groove 81 is provided on one side of the strip groove 112 and on the outer surface of the limit ring 8.

[0035] When the limit block 12 moves upward, it drives the protrusion 121 to move upward in the slide groove 111, preventing the limit block 12 from moving out of the first block 11. Through the strip groove 112 and the movable groove 81, the movable column 6 drives the connecting rod 14 to move up and down when it moves upward.

[0036] As shown in Figures 5-6, the bottom of the limit block 12 is fixedly connected to the fixed block 17, the top of the fixed block 17 is fixedly connected to the compression spring 18, the top of the compression spring 18 is fixedly connected to the bottom inner wall of the first clamping block 11, and the outer surfaces on both sides of the limit block 12 are provided with a limit opening 122, and a movable opening 123 is provided on one side of the limit opening 122.

[0037] The fixing block 17 facilitates fixing the compression spring 18, so that the limit block 12 can return to its original position when it moves up and down under the action of the compression spring 18. The limiting opening 122 facilitates the extrusion block 104 to extrude the limiting device, and the moving opening 123 facilitates the movement of the limiting device, so that the limiting device limits the limit block 12, thereby keeping the limit block 12 stable.

[0038] As shown in Figures 5-6, a limiting groove 131 is opened inside the second card block 13, and support blocks 19 are fixedly connected to the inner wall of the limiting groove 131 and on both sides of the bottom end of the second card block 13. A movable cavity is opened inside the support block 19, and the movable cavity runs through both sides of the second card block 13. The extrusion block 104 extends through the movable cavity to the inside of the limiting groove 131, and one end of it is located inside the movable opening 123. The top of the support block 19 is fixedly connected to the limiting card block 20.

[0039] Through the movable cavity inside the support block 19, the extrusion block 104 can pass through the movable cavity and move to both sides of the limit block 12 to support and fix the outside of the limit. The extrusion block 104 moves toward the inside of the limit block 12, squeezing the limit device so that the limit device is plugged into the limit card block 20, which is convenient for limiting the limit block 12 and supporting both sides of the limit block 12 to prevent the limit block 12 from moving.

[0040] As shown in Figures 7-8, the limiting device includes a moving block 21, the bottom end of the moving block 21 is movably connected to the moving mouth 123, the top of the moving block 21 is fixedly connected to a fixed rod 22, the fixed rod 22 is movably connected to the inside of the limiting block 12, and a moving plate 23 is provided at one end of the moving block 21. A connecting column 24 is hinged on one side of the moving plate 23, and a tension spring 25 and a limiting rod 26 are respectively connected on opposite sides of the end of the moving plate 23 away from the moving block 21. One end of the moving block 21 is fitted with one side of the moving plate 23, and a baffle 27 is fixedly connected to the connecting column 24 and one side of the tension spring 25. The baffle 27 is located inside the limiting block 12, and the moving block 21 is symmetrically arranged with the baffle 27 as the center.

[0041] The moving block 21 drives the fixed rod 22 to move toward the inside of the limit block 12, squeezing the moving plate 23, so that the first end of the moving plate 23 moves downward and the second end deflects upward, and the tension spring 25 is stretched, thereby deflecting the limit rod 26 to the outside of the bottom limit block 12, so that the limit rod 26 is plugged into the limit block 20. The symmetrical setting of the moving block 21 makes it easy to limit and fix the limit block 12 from both sides of the limit block 12, maintain the stability of the limit block 12, and prevent the limit block 12 from moving.

[0042] As shown in Figures 7-8, the shape of the limit block 20 is L-shaped, the top of the limit block 20 is fixedly connected to the inner wall of the limit groove 131, and the bottom end of the limit block 20 is provided with a circular groove 201, and the limit rod 26 is plugged into the inside of the circular groove 201.

[0043] When the limiting block 20 facilitates the limiting rod 26 to move out of the limiting block 12 , the limiting rod 26 is plugged into the circular groove 201 of the limiting block 20 , thereby facilitating the fixing of the top end of the limiting block 12 .

[0044] As shown in FIG9 , the present application also provides a method for using the low-voltage power outage monitoring device, the method comprising:

[0045] Step 1: Fix the fixing base 1 to the wall with screws, and power on the low-voltage power outage monitoring device by connecting the power supply. The magnetic core coil 5 generates a magnetic field, causing the movable column 6 to move upward under the action of the magnetic field, and the battery 61 is charged;

[0046] Step 2: When the movable column 6 moves upward, it drives the limiting ring 8 and the connecting rod 14 to move upward, so that the limiting block 12 moves upward, the compression spring 18 is stretched, and the protrusion 121 moves to the top of the slide groove 111. When the movable column 6 is attracted by the magnetic core coil 5, the top of the limiting block 12 moves to the inside of the second clamping block 13; the starting motor 9 drives the reverse double-threaded rod 101 to rotate, and the movable block 102 drives the support rod 103 to move closer to each other, so that the extrusion block 104 moves toward the inside of the second clamping block 13, so that the extrusion block 104 squeezes the limiting block 12;

[0047] Step 3: When the extrusion block 104 squeezes the limit block 12, the moving block 21 moves toward the inside of the limit block 12. The moving block 21 squeezes the moving plate 23, causing the first end of the moving plate 23 to deflect downward and the second end to deflect upward. The tension spring 25 is stretched, and the moving plate 23 drives the fixed rod 22 to rotate, causing one end of the fixed rod 22 to move out of the outside of the limit rod 26 and plug into the limit block 20, thereby maintaining the stability of the movable column 6.

[0048] Step 4: When the circuit is powered off, the magnetic core coil 5 no longer generates a magnetic field, and the movable column 6 will not be attracted, driving the limit block 12 to move downward, so that the movable column 6 is no longer fixed. The bottom of the movable column 6 is inserted into the middle of the contact copper sheet 16, and the power supply in the battery 61 supplies power to the alarm device through the contact copper sheet 16. The alarm device sounds an alarm to inform the user of the information.

[0049] Working principle: Fix the fixing base 1 to the wall with screws, and power on the device by turning on the power. At this time, the magnetic core coil 5 generates a magnetic field, which causes the movable column 6 to move upward, driving the limit ring 8 and the connecting rod 14 to move upward, and the limit block 12 moves upward. The compression spring 18 is stretched, causing the protrusion 121 to move to the top of the slide groove 111. When the movable column 6 is attracted by the magnetic core coil 5, the top of the limit block 12 moves to the inside of the second block 13, and then the motor 9 is started to rotate the reverse double-threaded rod 101. The movable block 102 drives the support rod 103 to approach each other, so that the extrusion block 104 moves toward the inside of the second block 13, so that the extrusion block 104 passes through the movable cavity inside the support block 19 and moves to both sides of the limit block 12, fixing and supporting the outside of the limit block 12, so as to facilitate the protection and stability of the movable column 6.

[0050] When the extrusion block 104 moves toward the inside of the limit block 12, the limit block 12 is squeezed, causing the moving block 21 to move toward the inside of the limit block 12, and the moving block 21 squeezes the moving plate 23, causing the first end of the moving plate 23 to deflect downward and the second end to deflect upward. The tension spring 25 is stretched, and the moving plate 23 drives the fixed rod 22 to rotate, so that one end of the fixed rod 22 moves out of the outside of the limit rod 26 and plugs into the limit block 20 to maintain the stability of the limit block 12. When the circuit is powered off, the magnetic core coil 5 no longer generates a magnetic field, and the movable column 6 will not be attracted. Under the action of gravity, the limit block 12 is driven to move downward, so that the movable column 6 is no longer fixed, and the bottom of the movable column 6 is inserted into the middle of the contact copper sheet 16. The power supply in the battery 61 will pass through the contact copper sheet 16 to energize the alarm device, and then an alarm is issued to inform the user of the information.

[0051] The beneficial effects of this application are:

[0052] 1. Through the coordinated use of the first clamping block 11, the second clamping block 13, the limit block 12, the extrusion device 10, the motor 9, the connecting rod 14, the fixing ring 15 and the movable column 6, the limit block 12 is driven upward by the movable column 6. Under the action of the motor 9, the extrusion device 10 fixes the limit block 12, so that the movable column 6 remains stable with the magnetic core coil 5, preventing the magnetic core coil 5 and the movable column 6 from being easily deformed or having poor contact after being vibrated, thereby causing false alarms.

[0053] 2. By cooperating with the extrusion block 104, the moving block 21, the moving plate 23, the tension spring 25, the limit rod 26 and the limit block 20, the extrusion block 104 is used to extrude the moving plate 23, so that the tension spring 25 is stretched, and the limit rod 26 is plugged into the limit block 20, thereby fixing the position of the limit block 12 and limiting the limit block 12 to prevent the limit block 12 from moving downward, thereby maintaining the stability of the limit block 12.
