DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a high-voltage power grid power failure instantaneous alarm device, including a fixing plate 1, a fixing rod 2, a connecting splint 3, a connecting groove 4, a connecting cap 5, an anti-slip rubber pad 6, a fixing bracket 7, an alarm table 8, an installation groove 9, a power failure alarm device 10, an installation plug plate 11, a connecting mechanism 12, a supporting column 13, a movable column 14, a protrusion 15 and a fixing block 16.

[0031] When using the high voltage power grid power failure instant alarm device, if Figure 1 , Figure 2 and Figure 3 As shown, first move each component to the corresponding position near the electric pole, then directly snap the fixing plate 1 onto the side of the electric pole, and at the same time, the front and rear ends of the fixing plate 1 are fixedly connected with the fixing rod 2, and the fixing rod 2 is inserted into the connecting grooves 4 at the front and rear ends of the connecting clamping plate 3, and then the connecting cap 5 connected to the outer surface of the fixing rod 2 by rotating the thread, the connecting cap 5 and the connecting clamping plate 3 are arranged in a close fit, so as to facilitate the limiting of the connection clamping plate 3 and the fixing rod 2, and clamp the fixing plate 1 and the connecting clamping plate 3 at the corresponding position on the outside of the electric pole, so as to facilitate the installation of the entire device at any position of different thicknesses on the electric pole, and the inner sides of the connecting clamping plate 3 and the fixing plate 1 are embedded with anti-skid rubber pads 6, and the anti-skid rubber pads 6 are arranged in a close fit on the outside of the electric pole to increase the friction force at the contact position with the electric pole, improve the stability of the connection position, and prevent slipping;

[0032] like Figure 4 , Figure 5 and Figure 6As shown, the left end of the fixed plate 1 is connected to the alarm platform 8 through the fixed bracket 7, and a mounting groove 9 is provided in the middle of the alarm platform 8. When the power-off alarm device 10 is installed, combined with the setting of the connecting mechanism 12, the connecting mechanism 12 includes a support column 13 fixedly connected to the upper end of the alarm platform 8, a movable column 14 rotatably connected to the upper end of the support column 13, a protrusion 15 for limiting and a fixed block 16 fixedly connected to the upper right end of the power-off alarm device 10. First, the movable column 14 is rotated to 90°, and the movable column 14 is rotated at the upper end of the support column 13. The torsion spring at the connection between the movable column 14 and the support column 13 undergoes elastic deformation, and the movable column 14 drives the protrusion 15 to rotate, and then the power-off alarm device 10 drives the installation plug plate 11 to be plugged into the mounting groove 9 in the middle of the alarm platform 8;

[0033] At this time, the movable column 14 is inserted into the fixed block 16, and the movable column 14 drives the protrusion 15 to pass through the fixed block 16, and then the movable column 14 is directly released. At this time, the torsion spring at the connection between the movable column 14 and the support column 13 restores elastic deformation, driving the movable column 14 to rotate at the upper end of the support column 13. At this time, the movable column 14 drives the protrusion 15 to rotate, so that the protrusion 15 is fitted on the side of the fixed block 16, as shown in Figure 4 The state shown makes it easy to install the limit between the power off alarm device 10 and the alarm station 8, and the overall operation is very convenient. When the power off alarm device 10 fails, the power off alarm device 10 can be directly removed from the side of the alarm station 8 by rotating the movable column 14. The disassembly and assembly are convenient and the maintenance is simple. After the power off alarm device 10 is installed, the power off alarm device 10 is used to detect and alarm the power off situation in the power grid. Moreover, the power off alarm device 10 in this scheme has the same structure as the power off alarm in the background technology comparison patent. It is an existing mature technology and is well known to those skilled in the art. It will not be described in detail here.
