Detailed Description of the Preferred Embodiments

[0023] In order to make the objectives and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific scope of protection claimed for the present utility model.

[0024] As Figures 1-4As shown in the figure, a power equipment operation fault warning device includes a mounting frame 101 and an alarm 102. A notch 103 for cooperating with the mounting frame 101 is provided at the rear side of the alarm 102. Positioning holes 104 are provided at the top of the mounting frame 101. The number of the positioning holes 104 is several and they are evenly distributed at the top of the mounting frame 101. Structure boxes 2 are fixedly connected to both sides of the alarm 102. The interior of the structure box 2 is a cavity, and a fixing mechanism is arranged inside the structure box 2; the fixing mechanism includes a cross plate 201, a spring 202, a connecting plate 203, a positioning block 204, a shaft body 205, a gear 206, a rack bar 207 and a rack 208. The cross plate 201 is fixedly connected to the inside of the structure box 2. One end of the spring 202 is fixedly connected to the bottom of the cross plate 201. The connecting plate 203 is fixedly connected to the other end of the spring 202. One end of the positioning block 204 is fixedly connected to the bottom of the connecting plate 203. The other end of the positioning block 204 penetrates through the structure box 2 and extends into the positioning hole 104. The shaft body 205 is connected to the inner wall of the structure box 2 through a bearing. The gear 206 is sleeved on the surface of the shaft body 205. The number of the gears 206 is three and they are evenly distributed on the surface of the shaft body 205. One end of the rack bar 207 is fixedly connected to the top of the connecting plate 203. The other end of the rack bar 207 penetrates through the top of the cross plate 201. The rack bar 207 is meshed and connected to one side of the middle gear 206. One end of the rack 208 is arranged inside the structure box 2. The other end of the rack 208 penetrates through the front side of the structure box 2. The rack 208 is respectively meshed and connected to the tops of the two side gears 206. When it is necessary to disassemble the alarm 102 for maintenance and repair, the staff can pull the rack 208 forward through the handle 6. When the rack 208 moves forward, it will drive the two side gears 206 meshed and connected to rotate forward. When the two side gears 206 rotate forward, they will drive the shaft body 205 and the middle gear 206 to rotate forward at the same time. When the middle gear 206 rotates forward, it can drive the rack bar 207 meshed and connected to move upward. When the rack bar 207 moves upward, it will drive the connecting plate 203 to move upward at the same time and compress the spring 202. When the connecting plate 203 moves upward, it can drive the positioning block 204 to move upward at the same time. When the positioning block 204 moves upward, it will disengage from the positioning hole 104. Then the staff can pull the alarm 102 forward from the mounting frame 101, so that the notch 103 at the rear side of the alarm 102 is separated from the mounting frame 101, and the alarm 102 can be quickly disassembled for maintenance and repair. The operator can perform daily maintenance and troubleshooting more easily, reduce the operation difficulty, reduce the monitoring downtime of the equipment, and provide a more reliable warning work.

[0025] As Figures 2-4As shown in the figure, sliders 301 are fixedly connected to the top of the rack 208 respectively. A sliding rod 302 is fixedly connected to the inner wall of the structural box 2. The sliders 301 are fixedly connected to the surface of the sliding rod 302 respectively. When the rack 208 is pulled forward to move, the rack 208 will drive the sliders 301 to slide on the surface of the sliding rod 302. Thus, with the cooperative connection between the sliders 301 and the sliding rod 302, the rack 208 can be assisted in being limited, preventing the rack 208 from shaking or deviating when the rack 208 is pulled to move, and avoiding the deviation of the rack 208 from affecting the normal operation of the entire fixing mechanism.

[0026] As Figure 4 shown in the figure, a mating groove 4 is formed in the top of the cross plate 201. The mating groove 4 is used in cooperation with the toothed rod 207. By providing the mating groove 4, the toothed rod 207 can flexibly move up and down inside the mating groove 4, and the toothed rod 207 has sufficient moving space, avoiding movement interference caused by the toothed rod 207 colliding with the cross plate 201 when moving up and down.

[0027] As Figures 2-4 shown in the figure, a limiting rod 5 is movably arranged inside the spring 202. The connecting plate 203 is slidably connected to the surface of the limiting rod 5. One end of the limiting rod 5 is fixedly connected to the inner wall of the structural box 2, and the other end of the limiting rod 5 is fixedly connected to the bottom of the cross plate 201. When the toothed rod 207 drives the connecting plate 203 to move and squeezes the spring 202, in order to avoid the deviation of the connecting plate 203, the connecting plate 203 can be limited with the assistance of the limiting rod 5, so that the connecting plate 203 makes a vertical movement. At the same time, it is avoided that the connecting plate 203 drives the positioning hole 104 to displace and cannot be accurately connected with the positioning hole 104.

[0028] As Figures 1-4 shown in the figure, a handle 6 is fixedly connected to the front side of the rack 208. The shape of the handle 6 is long strip-shaped. The rack 208 can be smoothly pulled through the handle 6. Under the action of the handle 6, a convenient and comfortable gripping point can be provided for the staff, enabling the staff to quickly disassemble the alarm 102.

[0029] As Figure 4 shown in the figure, the bottom end of the positioning block 204 is provided as an inclined surface, and the angle of the inclined surface is 45 degrees. When installing the alarm 102, the staff can directly fit the notch 103 behind the alarm 102 with the mounting bracket 101 and push it backward. The backward pushing of the alarm 102 can drive the fixing mechanism to move backward, making the inclined surface on the positioning block 204 contact with the mounting bracket 101. Under the action of the inclined surface, the friction coefficient between the positioning block 204 and the mounting bracket 101 can be reduced, enabling the positioning block 204 to be smoothly connected with the positioning block 204, and thus the alarm 102 can be quickly installed.

[0030] As Figure 1As shown, there are several positioning holes 104, which are evenly distributed on the top of the mounting bracket 101. Setting multiple positioning holes 104 facilitates the staff to flexibly adjust the installation position of the alarm 102. When the equipment or environment changes, the position can be flexibly adjusted to adapt to the new conditions. At the same time, by adjusting the position, the possible interference or influence on the alarm 102 can be avoided, improving the overall reliability of the system.

[0031] The working principle of the present utility model is as follows: When it is necessary to disassemble the alarm 102 for maintenance and repair, the staff can pull the rack 208 forward through the handle 6. The forward movement of the rack 208 will drive the two side gears 206 engaged and connected to rotate forward. The forward rotation of the two side gears 206 will simultaneously drive the shaft body 205 and the middle gear 206 to rotate forward. When the middle gear 206 rotates forward, it can drive the toothed rod 207 engaged and connected to move upward. The upward movement of the toothed rod 207 will drive the connecting plate 203 to move upward simultaneously and compress the spring 202. When the connecting plate 203 moves upward, it can drive the positioning block 204 to move upward. The upward movement of the positioning block 204 will disengage from the positioning hole 104. Then the staff can pull the alarm 102 forward from the mounting bracket 101, separating the notch 103 at the rear of the alarm 102 from the mounting bracket 101, and the alarm 102 can be quickly disassembled for maintenance and repair. The operator can perform daily maintenance and troubleshooting more easily, reducing the operation difficulty.

[0032] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special instructions and limitations.
