DETAILED DESCRIPTION

[0034] Example 1: As shown in the present application provides a generator set alarm device, comprising: Figures 1-5

[0035] Rotation speed monitoring device 1 for detecting the state of the generator set shaft rotation, comprising monitoring shell 102, monitoring shell 102 side fixedly connected with processor 104, processor 104 top fixedly connected with first indicator light 101, monitoring shell 102 inner wall bottom fixedly connected with support table 107, monitoring shell 102 middle part is provided with rotating device 2 for connecting with the shaft and outputting the state of the shaft.

[0036] ​It should be noted that by setting the rotating speed monitoring device 1, when the generator set is normally operated, the paddle 202 on the main shaft 201 will constantly hit the fixed plate 1010 on the slide plate 106 and push the slide plate 106 to move, so that the second interface 109 on the slide plate 106 is constantly in contact with the first interface 108, so that the first indicator light 101 is powered on, and the first indicator light 101 will be in a stroboscopic state. When the main shaft 201 stops, the motion state of the slide plate 106 stops, the second interface 109 is not in contact with the first interface 108, and the capacitor 103 will be continuously discharged for a period of time. After discharge, the structure of the electric heating super fiber 105 gradually elongates, so that the second interface 109 is in contact with the first interface 108, and the first indicator light 101 will be constantly on after being turned off. At this time, the rotating shaft of the generator set is in the stop state in the working process, and the real-time state of the rotating shaft of the generator set can be directly observed according to the real-time change of the first indicator light 101, so that different sudden states can be better coped with.

[0037] The top end of the support table 107 is in a rectangular array and has a plurality of balls 1011. The top end of the support table 107 is slidably connected with the slide plate 106. The top end of the slide plate 106 is fixedly connected with the fixed plate 1010 in the middle. The one side of the slide plate 106 is fixedly connected with the second interface 109 in the middle. The inner side wall of the monitoring shell 102 is fixedly connected with the first interface 108 in the middle. The other side of the slide plate 106 is fixedly connected with two electric heating super fibers 105. The inner side wall of the monitoring shell 102 is fixedly connected with the capacitor 103 at the upper position of the rear end.

[0038] It should be noted that after the capacitor 103 discharges the electric heating super fiber 105, the length of the electric heating super fiber 105 changes, so that the first interface 108 cooperates with the second interface 109. Therefore, the first indicator light 101 will eventually be in a constant state. However, when the first indicator light 101 is constantly on, the rotating speed monitoring device 1 needs to be first stopped for self-checking. By manually rotating the main shaft, the fixed plate 1010 is actuated by the paddle 202, and whether the first indicator light 101 flashes is observed. If it flashes, the rotating shaft of the generator set is stopped. If there is no change, the paddle 202 or the torsional spring 205 in the rotating device 2 is damaged.

[0039] The rotating device 2 comprises a main shaft 201. The middle of the side wall of the main shaft 201 is in a circumferential array and has two mounting frames 203. The inner side wall of the mounting frame 203 is rotatably connected with the paddle 202. The bottom end of the paddle 202 is fixedly connected with the fixed rod 204. The side wall of the fixed rod 204 is fixedly connected with the torsional spring 205.

[0040] The first interface 108 and the second interface 109 are located on the same horizontal axis. The first interface 108 passes through the monitoring shell 102 and is electrically connected to the processor 104. Two electrothermal microfibers 105 are fixedly connected to the other side of the inner wall of the monitoring shell 102. The electrothermal microfibers 105 are made of carbon fiber and silicone rubber spinning and are spring-shaped. Both electrothermal microfibers 105 are electrically connected to the capacitor 103. Several ball bearings 1011 are slidably connected to the bottom end of the slide plate 106. A groove is opened in the middle of the top of the support platform 107. The middle of the bottom end of the slide plate 106 is slidably connected to the middle of the bottom end of the slide plate 106.

[0041] It should be noted that the electrothermal microfiber 105 is made of carbon fiber and silicone rubber using electrospinning. When energized, it will shrink and deform, and when the energizing is stopped, it will return to its original state. Furthermore, since the electrothermal microfiber 105 is a spring-like structure that contracts when energized, it can make the slide plate 106 return to its initial position, at which time the first interface 108 and the second interface 109 are disconnected.

[0042] The main shaft 201 completely penetrates the side wall of the housing 301 and the monitoring housing 102. The paddle 202 and the fixing plate 1010 are located on the same vertical axis. Both mounting brackets 203 are fixedly connected to the side wall of the main shaft 201. The two ends of the torsion spring 205 are fixedly connected to the side wall of the main shaft 201 respectively.

[0043] Working principle: When the generator set is running normally, the paddle 202 on the main shaft 201 will continuously strike the fixed plate 1010 on the slide plate 106 as the main shaft 201 rotates, and push the slide plate 106 to move, so that the second interface 109 on the slide plate 106 continuously contacts the first interface 108, so that the first indicator light 101 is energized and will be in a flashing state. When the main shaft 201 stops rotating, the movement of the slide plate 106 stops, the second interface 109 and the first interface 108 are no longer in contact, the capacitor 103 will continuously discharge for a period of time, and the electrothermal microfiber 105 will gradually elongate its own structure after discharge, so that the second interface 109 contacts the first interface 108, and the first indicator light 101 will stay on after it is turned off. At this time, the generator set shaft is in a stopped state during operation.
