[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a power failure alarm device for a low-voltage vibrating device in an electrostatic precipitator, including an audible and visual alarm 3. A power failure alarm mechanism 2 is installed at one end of the audible and visual alarm 3. The power failure alarm mechanism 2 includes a mounting box 21. One side of the mounting box 21 is fixedly connected to one end of the audible and visual alarm 3. A cover plate 23 is snapped onto one side of the mounting box 21. A power failure monitoring module 22 is fixedly connected inside the cover plate 23. A battery 24 is installed on one side of the power failure monitoring module 22. An installation mechanism 1 is installed on the other side of the mounting box 21. The installation mechanism 1 includes a fixing frame 11 and two shifting racks 111. One side of the fixing frame 11 is fixedly connected to the mounting box 21, and one end of each shifting rack 111 is fixed... A sliding plate 116 is connected to the frame. A movable plate 14 is fixedly connected to one side of the two sliding plates 116. A clamping plate 15 is fixedly connected to one end of the movable plate 14. A rotating rod 114 is rotatably connected to one side of the fixed frame 11. A fixed plate 19 is fixedly connected to one end of the rotating rod 114. A transmission gear 110 is fixedly connected to the outside of the rotating rod 114. The two sides of the transmission gear 110 mesh with two shifting racks 111 respectively. A fixed seat 13 is fixedly connected to the other side of one of the sliding plates 116. An electric push rod 12 is fixedly connected to one side of the fixed seat 13. A mounting seat 16 is fixedly connected to one side of the electric push rod 12. One side of the mounting seat 16 is fixedly connected to one side of the fixed frame 11.

[0023] The electric push rod 12 can move the fixed base 13, and the sliding plate 116 connected to one end of the fixed base 13 moves accordingly. The movement of the sliding plate 116 drives the displacement rack 111 connected to it to move. Through the meshing between the two displacement racks 111 and the transmission gear 110, the other displacement rack 111 is driven to move, so that the two moving plates 14 move synchronously. The distance between the two clamping plates 15 is adjusted so that the two clamping plates 15 are clamped at the installation position, thereby fixing the power failure alarm mechanism 2 to the low-voltage vibration of the electrostatic precipitator. The power failure monitoring point of the control power supply device has a cover plate 23 snapped onto one side of the mounting box 21. The cover plate 23 is fixed to the mounting box 21 to protect the internal structure of the mounting box 21. The power failure monitoring module 22 is equipped with a voltage transformer for voltage detection. When the control power fails, the voltage across the coil drops rapidly, the normally closed contact closes, and a power failure alarm trigger signal is output. The battery 24 is used to provide power to the entire device. An audible and visual alarm 3 is installed on the outside of the mounting box 21 to provide audible and visual alarms for the alarm signal.

[0024] Example 2: Figure 1 - Figure 4 As shown, a sliding block 113 is fixedly connected to one side of each of the two sliding plates 116, and a guide rod 112 is slidably connected to the middle of the sliding block 113; a fixing block 17 is fixedly connected to the end of the guide rod 112, and one end of the fixing block 17 is fixedly connected to one side of the fixing frame 11; a positioning block 18 is fixedly connected to one side of the fixing frame 11, and a sliding wheel 115 is rotatably connected to one end of the positioning block 18, and the outer side of the sliding wheel 115 is slidably connected to one side of the shifting rack 111.

[0025] The overall effect of this embodiment is that during the movement of the two sliding plates 116, the sliding block 113 slides outside the guide rod 112, which can fix the two sliding plates 116 to make linear movement, while driving the two moving plates 14 to move. When the two shifting racks 111 move, the shifting racks 111 contact the outer side of the sliding wheel 115, causing the sliding wheel 115 to rotate, and one side of the shifting rack 111 is in contact with the fixed plate 19, thereby fixing the movement path of the shifting racks 111, making the movement of the two shifting racks 111 more stable, and thus adjusting the distance between the two clamping plates 15.

[0026] The working principle and method of using the device: the fixed seat 13 is moved by the electric push rod 12, the sliding plate 116 is moved, the shift rack 111 connected therewith is moved, another shift rack 111 is moved, the moving plate 14 is moved, the distance between the two clamping plates 15 is adjusted, the power failure alarm mechanism 2 is fixed on the monitoring position, the cover plate 23 is fixed on the installation box 21, the internal structure of the installation box 21 is protected, the power failure monitoring module 22 is used for power failure monitoring, the output power failure alarm trigger signal is output when the control power is lost, and the sound and light alarm 3 is used for sound and light alarm of the alarm signal.

[0027] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still belongs to the protection scope of the present application.
