Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a low-voltage switchgear equipped with Internet of Things (IoT) monitoring. Background Technology

[0002] Under the general trend of smart grid construction, the traditional low-voltage switchgear model, which relies on manual inspection and has delayed data acquisition, can no longer meet the power system's requirements for real-time monitoring of equipment operating status and accurate fault prediction. Smart grids emphasize the interconnection and intelligent control of all aspects of the power system. As a key node in power distribution, low-voltage switchgear needs to incorporate Internet of Things (IoT) technology to transform from "dumb devices" to "intelligent terminals," thereby better integrating into the smart grid system and improving the overall operating efficiency and intelligence level of the power system.

[0003] In a current low-voltage switchgear equipped with IoT monitoring, the smoke detector is located in a fixed position. Due to the cooling fan, if smoke is generated inside the cabinet, it may be quickly drawn away and expelled by the fan, causing the smoke detector to fail to sound. This limitation is significant and its practicality is poor. In addition, if a short circuit occurs inside this type of low-voltage switchgear equipped with IoT monitoring, there is no mechanism for quickly discharging the electricity, which could lead to an explosion inside, resulting in poor safety. Utility Model Content

[0004] The purpose of this invention is to address the problems in existing technologies where smoke detectors are fixed in position, and due to the cooling fan, smoke generated inside the cabinet may be quickly drawn away and discharged, causing the smoke detector to fail to alarm. Furthermore, if a short circuit occurs inside the cabinet, there is no mechanism for quickly discharging electricity, which could lead to an explosion inside, resulting in poor safety. Therefore, this invention proposes a low-voltage switch cabinet with IoT monitoring.

[0018] 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.

[0019] 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.

[0020] Example 1, such as Figure 1-4As shown, this utility model provides a low-voltage switchgear with IoT monitoring, including a cabinet 1. Both ends of the cabinet 1 have connecting cavities 4. Both ends of the cabinet 1 are fixed with connecting pipes 21 that match the connecting cavities 4. One of the connecting pipes 21 is equipped with a movable frame 8. A first motor 9 is installed at the end of the movable frame 8 facing the cabinet 1. A fan 10 is fixed at the output end of the first motor 9. A connecting groove 11 is opened inside the movable frame 8. Two brackets 12 are fixed at the end of the movable frame 8 away from the first motor 9. A controller 22 and a smoke alarm 13 are respectively installed at the ends of the two brackets 12 facing the connecting groove 11. A data transmission device 15 is installed on the inner bottom wall of the cabinet 1. An installation frame 17 is installed inside the cabinet 1. Both ends of the installation frame 17 are fixed with first conductive plates 19. A second conductive plate 20 is fixed at the bottom end of the first conductive plate 19. The bottom end of the second conductive plate 20 penetrates the cabinet 1 and is located outside the cabinet 1. A drive structure 14 for driving the movable frame 8 to move up and down is provided inside the connecting pipe 21.

[0021] The overall effect of Embodiment 1 is that, through the arrangement of the movable frame 8 and the connecting groove 11, when the first motor 9 runs and drives the fan 10 to rotate, it draws in air to dissipate heat from the cabinet 1. A portion of the drawn-in air will be discharged through the connecting groove 11 in the movable frame 8. The smoke alarm 13 is installed at the outlet of the connecting groove 11 through the bracket 12. Even if smoke generated in the cabinet 1 is drawn in by the fan 10, the smoke alarm 13 installed at the outlet of the connecting groove 11 can still detect it in time, thus enhancing safety. In addition, through the arrangement of the first conductive plate 19 and the second conductive plate 20, the device can guide the power generated by short circuits to the outside of the cabinet 1 and to the ground pre-embedded by the second conductive plate 20 in time, thus enhancing safety. Through the operation of the drive structure 14, the movable frame 8 can be raised and lowered as a whole. On the one hand, it can dissipate heat from electronic components installed at different heights in the cabinet 1, and on the other hand, it can detect smoke at different heights in time, thus enhancing practicality. The controller 22 of this device can control the operation of the first motor 9, the second motor 1401, the smoke alarm 13, and the data transmission device 15.

[0022] Example 2, as Figure 1-4As shown, the drive structure 14 includes a second motor 1401 installed on the top wall of the connecting pipe 21. The output end of the second motor 1401 is fixed with a screw 1402. Both ends of the movable frame 8 are fixed with connecting blocks 1403. One connecting block 1403 is threadedly connected to the screw 1402. The other connecting block 1403 is slidably connected with a limit post 1404. The bottom end of the screw 1402 is rotatably connected to the connecting pipe 21. Both ends of the limit post 1404 are fixed to the connecting pipe 21. The bottom end of the cabinet 1 is fixed with a base 16. The bottom end of the second conductive sheet 20 passes through the base 16 and is located below the base 16. The opposite ends of the two connecting pipes 21 are each fitted with a dustproof mesh frame 5 by bolts 6. The opposite ends of the two dustproof mesh frames 5 are each provided with mounting holes 7 at the four corners. The front end of the cabinet 1 is connected to a door panel 2 by a pin. A handle 3 is fixed on the outer wall of the door panel 2. Multiple wiring holes 18 are provided in the mounting frame 17.

[0023] The overall effect of embodiment 2 is that the operation of the second motor 1401 can drive the screw 1402 to rotate, so that the moving frame 8 can be raised and lowered under the limiting cooperation of the limiting column 1404 and the connecting block 1403. On the one hand, it can heat up the electronic components installed at different heights in the cabinet 1, and on the other hand, it can detect the smoke at different heights in time, making it more practical. The dustproof mesh frame 5 can be set to prevent the air flowing through the two connecting pipes 21 from being dustproofed. The bolts 6 can be used to install and remove the two dustproof mesh frames 5.

[0024] Working principle: When using this device, the second conductive plate 20 is pre-embedded in the ground. Through the arrangement of the movable frame 8 and the connecting groove 11, when the first motor 9 runs, driving the fan 10 to rotate and draw air from the cabinet 1 for heat dissipation, some of the drawn air will be discharged through the connecting groove 11 in the movable frame 8. The smoke alarm 13 is installed at the outlet of the connecting groove 11 via the bracket 12. Even if smoke generated inside the cabinet 1 is drawn in by the fan 10, the smoke alarm 13 installed at the outlet of the connecting groove 11 can still detect it in time, enhancing safety. Furthermore, through the arrangement of the first conductive plate 19 and the second conductive plate 20, this device can promptly guide the electricity generated by short circuits, etc., out of the cabinet 1 and onto the second conductive plate 20. Within the pre-embedded ground, safety is enhanced. The operation of the second motor 1401 drives the screw 1402 to rotate, allowing the movable frame 8 to rise and fall under the limiting cooperation of the limit column 1404 and the connecting block 1403. On the one hand, it can dissipate heat from electronic components installed at different heights inside the cabinet 1, and on the other hand, it can detect smoke at different heights in a timely manner, making it more practical. The dustproof mesh frame 5 can prevent dust from entering the air flowing through the two connecting pipes 21. The bolts 6 can be used to install and remove the two dustproof mesh frames 5. When the smoke alarm 13 detects smoke, it will send a signal to the data transmission device 15, which will then send a signal to the monitoring personnel for collection.

[0025] The wiring diagrams of the controller 22, the first motor 9, the second motor 1401, the smoke alarm 13, and the data transmission device 15 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the controller 22, the first motor 9, the second motor 1401, the smoke alarm 13, and the data transmission device 15 will not be explained in detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
