[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 A fire detection alarm assembly for a power distribution cabinet is shown, comprising:

[0026] A power distribution cabinet body 1, and the power distribution cabinet body 1 is used for storing power supply devices;

[0027] An alarm component 2, which is installed in the power distribution cabinet body 1, and is used to monitor the status of electrical appliances in the power distribution cabinet body 1 in real time;

[0028] Furthermore, the alarm component 2 includes a controller 24 and a spark detector 22 installed in the distribution cabinet body 1 and a temperature sensor 21 installed on the electrical appliance, and the spark detector 22 is equipped with a mounting base 23 fixed to the distribution cabinet body 1, and the mounting base 23 is hinged to the connecting plate 32; the alarm component 2 is a component well known in the art, so it will not be described in detail here.

[0029] As can be seen from the above, when in use, the temperature sensor 21 is first installed on the surface of the heating element according to the number of heating elements required, so as to achieve the purpose of comprehensive monitoring. In addition, the temperature in the distribution cabinet body 1 will have an increasing process before the fire occurs. Sparks and flames are the main manifestations of fire in the distribution cabinet. In addition, the spark detector 22 can detect the spark and flame information of the distribution cabinet body 1 in real time, and transmit the alarm information to the controller 24. Then the controller 24 can collect the data collected by the spark detector 22 and determine whether a fire has occurred. At the same time, the temperature information collected by the temperature sensor 21 is transmitted to the controller 24. The controller 24 can receive and calculate to determine the temperature change trend in the distribution cabinet body 1. When the temperature rises sharply, the controller 24 can issue a fire warning. The controller 24 can realize the warning and alarm functions of the fire alarm through program operation.

[0030] refer to Figure 1-Figure 4 As shown, the mounting assembly 3 is used to flexibly mount the alarm component 2 in the cabinet 1 of the power distribution cabinet. The mounting assembly 3 includes a mounting frame 31 and a connecting plate 32 mounted on the alarm component 2, and a plurality of second threaded holes 34 opened at the top of the mounting frame 31, and a first threaded hole 33 is opened at the top of the connecting plate 32, a threaded column 35 is screwed on the connecting plate 32, and the threaded column 35 is screwed into the second threaded hole 34 corresponding to the first threaded hole 33 through the first threaded hole 33, a guide assembly for limiting the connection plate 32 with the alarm component 2 is provided, and a second threaded hole 34 is provided on the mounting frame 31. The protective component 4 is provided with protection; the guide component includes a limit ring 38 fixed on one side of the mounting seat 23 and a connecting column 37 fixed on one side of the connecting plate 32, and the connecting column 37 passes through the mounting seat 23 and extends into the limit ring 38, a first stopper 39 is fixed to the outside of the connecting column 37, and the first stopper 39 is located in the limit ring 38, a second stopper corresponding to the first stopper 39 is fixed in the limit ring 38, and the second stopper abuts against the first stopper 39; a guide groove 36 for the threaded column 35 to slide into is also provided at the top of the mounting frame 31, and the guide groove 36 is communicated with the inside of the second threaded hole 34.

[0031] When the spark detector 22 is installed, the mounting base 23 is first installed in the distribution cabinet body 1, and the threaded column 35 is screwed into the first threaded hole 33 with one end exposed to the outside, and then the exposed end of the threaded column 35 is inserted into the guide groove 36. At this time, the threaded column 35 slides along the guide groove 36 to adjust the distance between the spark detector 22 and the distribution cabinet body 1 to avoid conflict between the spark detector 22 and the distribution cabinet body 1, and the spark detector 22 is rotated to rotate the threaded column 35 along the guide groove 36, so that the angle between the spark detector 22 and the mounting base 23 is fine-tuned, which can prevent the spark detector 22 and the electrical appliances in the distribution cabinet body 1 from being flexibly adjusted to prevent conflict caused by too close contact, and the threaded column 35 is rotated to screw it into one of the second threaded holes 34, so that the threaded column 35 and the mounting bracket 31 are locked. The spark detector 22 is then installed, and then the spark detector 22 is driven by the wave to drive the connecting plate 32 to rotate, so that the connecting plate 32 and the mounting seat 23 rotate, and the spark detector 22 is adjusted up and down in the distribution cabinet body 1. However, the rotation process of the connecting plate 32 drives the connecting column 37 to rotate along the mounting seat 23 and the limit ring 38. As the connecting column 37 rotates, it drives the first stop block 39 to rotate along the limit ring 38, and then the first stop block 39 and the second stop block conflict with or move away from each other, and then the spark detector 22 is installed at a suitable position in the distribution cabinet body 1, so that the spark detector 22 can be flexibly installed in the distribution cabinet body 1, which can reduce the difficulty of installing the spark detector 22, thereby solving the problem of installation between the existing mounting seat 23 and the distribution cabinet, which is not convenient for flexible adjustment of the spark detector 22, and may require more time during installation, thereby improving the installation efficiency of the alarm component.

[0032] In addition, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the protective component 4 includes a connecting plate 44 slidably mounted on the second threaded hole 34 and a plug-in slot 41 provided on one side of the mounting frame 31, and a plug-in plate 42 is installed in the plug-in slot 41, and a connecting cavity 43 for the connecting plate 44 to slide into is provided on one side of the plug-in plate 42, and an elastic component for driving the connecting plate 44 to reset is provided in the connecting cavity 43; the elastic component includes a slide plate 45 fixed on one side of the connecting plate 44 and a limiting groove provided in the connecting cavity 43, and the slide plate 45 is located in the limiting groove, and a spring 46 is connected between the limiting groove and the slide plate 45.

[0033] Before the threaded column 35 is inserted into the second threaded hole 34, the plug-in plate 42 is first inserted into the plug-in slot 41, and the connecting plate 44 is pushed to slide along the connecting cavity 43. At this time, the connecting plate 44 moves to drive the slide plate 45 to slide along the limiting groove, and the spring 46 is squeezed between the limiting groove and the slide plate 45, and the connecting plate 44 continues to move to slide into the slide plate 45, so that there is a gap between the connecting plate 44 and the connecting cavity 43, and then the threaded column 35 is inserted into the gap and screwed into the connecting cavity 43. Therefore, when the remaining second threaded holes 34 are not in use, they and the connecting plate 44 will cover the second threaded holes 34, thereby protecting the second threaded holes 34, reducing their exposure to the outside world, reducing the accumulation of debris that affects the smoothness of their movement, and further improving the installation efficiency of the alarm component.

[0034] Furthermore, a stopper is fixed on one side of the plug board 42 extending to the outside of the plug slot 41, and the length of the stopper is adapted to the plug slot 41; based on this, the setting of the stopper makes it easier for the user to apply force when holding it, thereby increasing the pulling force when the plug board 42 is pulled, thereby achieving the purpose of speeding up the assembly or disassembly operation.
