[0023] Example 1:
[0024] Please see Figures 1-4As shown, a building electrical fault alarm device includes: a mounting plate 1, a movable seat 2 slidably disposed on the outer side wall of the mounting plate 1, a device body 3 connected to the top of the movable seat 2 via a connecting component, a top plate 4 fixedly disposed on the outer side wall of the mounting plate 1, a lead screw 6 rotatably disposed on the outer side wall of the top plate 4, the end of the lead screw 6 away from the top plate 4 passing through the movable seat 2 and connected to a mounting frame 5, the lead screw 6 and the movable seat 2 being threadedly connected, and an adjustment mechanism being provided inside the mounting frame 5;
[0025] The adjustment mechanism includes a rotating rod 7 rotatably mounted on the inner side wall of the mounting frame 5, a lead screw 6 passing through and rotatably mounted on the mounting frame 5, and the ends of the lead screw 6 and the rotating rod 7 being fixedly connected by a coupling. The mounting frame 5 is provided with an adjustment assembly.
[0026] As can be seen from the above, the device body 3 is equipped with a detection module, a signal processing module, a control module, an alarm module and a communication module. Through the coordinated work of multiple modules, the device body 3 can detect and alarm building electrical faults in a timely and accurate manner, ensuring the safe and stable operation of the building electrical system.
[0027] The detection module includes voltage sensors, current sensors, leakage current sensors, temperature sensors, and smoke detection sensors. The voltage sensor measures whether the line voltage is within the rated range; the current sensor detects the current magnitude and whether there is an overload; the leakage current sensor monitors whether there is leakage; the temperature sensor monitors the temperature of electrical equipment and lines; and the smoke detection sensor monitors smoke. Multiple sensors work together to monitor building electrical systems.
[0028] Rotating the knob 9 drives the worm gear 10 to rotate, which in turn drives the worm wheel 8 to rotate. This causes the worm wheel 8 to rotate the rotating rod 7 and the lead screw 6. The threaded connection between the lead screw 6 and the movable seat 2 allows the movable seat 2 to slide up and down along the mounting plate 1, thereby adjusting the height of the device body 3. This facilitates disassembly and assembly at a low position, avoids the risks of operating at height, and improves the safety and convenience of installation and maintenance.
[0029] Specifically, regarding the aforementioned adjustment components, please refer to... Figure 1 and Figure 2 As shown, the adjustment assembly includes a worm gear 8 fixedly sleeved on the outer wall of the rotating rod 7, a knob 9 provided on the outside of the mounting frame 5, a worm 10 fixedly provided on the outer wall of the knob 9, the end of the worm 10 passing through the outer wall of the mounting frame 5 and rotatably connected to the inner wall of the mounting frame 5, and the worm gear 8 and the worm 10 meshing with each other.
[0030] As can be seen from the above, when the knob 9 is turned, the worm 10 drives the worm wheel 8 to rotate, which in turn causes the rotating rod 7 and the lead screw 6, which are fixedly connected to the worm wheel 8, to rotate synchronously. Since the lead screw 6 is connected to the moving seat 2 by a thread, the rotation of the lead screw 6 is converted into the linear movement of the moving seat 2 along the outer wall of the mounting plate 1, thereby achieving precise adjustment of the height of the device body 3. This worm wheel 8 and worm 10 transmission method has self-locking properties, which can ensure that the moving seat 2 is stably fixed in the adjusted position and will not slide down due to the weight of the device, thus ensuring the stability of the device body 3 during installation.
[0031] Specifically, regarding the aforementioned connection components, please refer to... Figure 3 and Figure 4 As shown, the connecting assembly includes a connecting plate 11 fixedly installed on the back of the device body 3. A pad 12 is fixedly installed on the outer wall of the connecting plate 11. The outer wall of the pad 12 and the outer wall of the movable seat 2 are in close contact. Two symmetrically arranged connecting blocks 13 are fixedly installed on the outer wall of the connecting plate 11. A connecting groove adapted to the connecting blocks 13 is opened on the outer wall of the movable seat 2. The connecting blocks 13 are inserted into the connecting groove. A limiting component is provided between the connecting blocks 13 and the connecting groove.
[0032] The limiting component includes a limiting block 14 disposed on the connecting block 13. The limiting block 14 is arc-shaped on the outer side wall of the end facing the movable seat 2. A limiting groove is opened on the inner side wall of the connecting groove, and the limiting block 14 is inserted into the limiting groove.
[0033] The outer wall of the connecting block 13 is provided with a movable groove that is adapted to the limiting block 14. The outer wall of the limiting block 14 and the inner wall of the movable groove are slidably connected. A first spring 15 is fixedly provided on the outer wall of the limiting block 14. The end of the first spring 15 away from the limiting block 14 is fixedly connected to the inner wall of the movable groove.
[0034] As can be seen from the above, by setting and using the connecting component and the limiting component, when the device body 3 needs to be installed, the connecting block 13 is aligned with the connecting groove and inserted, and the limiting block 14 is automatically locked into the limiting groove under the elastic force of the first spring 15, realizing quick connection without additional tools, ensuring the stability of the connection between the device body 3 and the moving seat 2, and greatly facilitating the disassembly and installation of the device, improving maintenance efficiency, and saving manpower and time costs.
[0035] Example 2:
[0036] refer to Figure 3 and Figure 4 As shown, an installation groove 1 is provided on the inner side wall of the limiting groove. A push block 16 is provided inside the installation groove 1. The push block 16 and the limiting block 14 are arranged opposite to each other. A toggle block 17 is fixedly provided on the outer side wall of the push block 16. The outer side wall of the toggle block 17 passes through the installation groove 1 and extends outward. A moving opening adapted to the toggle block 17 is provided on the inner side wall of the installation groove 1.
[0037] As can be seen from the above, during disassembly, by pushing the push block 17 to drive the push block 16 to squeeze the limiting block 14, the limiting block 14 is retracted into the movable groove, and the connecting block 13 can be easily pulled out. The disassembly operation is simple and convenient.
[0038] Preferably, the top and bottom of the device body 3 are provided with protective plates 18. The protective plates 18 are fixedly installed on the outer wall of the movable seat 2. The outer wall of the protective plate 18 is provided with a second mounting groove. The inner wall of the second mounting groove is slidably provided with a top block 19. The outer wall of the top block 19 is fixedly connected to the outer wall of the toggle block 17. A second spring 20 is fixedly provided between the outer wall of the top block 19 and the inner wall of the second mounting groove.
[0039] As can be seen from the above, the protective plate 18 can effectively protect the device body 3 from external mechanical collisions and harsh environments, and extend the service life of the device. When the device body 3 is disassembled, the top block 19 is pushed by the toggle block 17, which compresses the second spring 20. The second spring 20 provides a reset force after the top block 19 is pushed, so that the top block 19 drives the toggle block 17 and the push block 16 to automatically return to their original positions after being released.
