Description

Technical Field

[0001] This utility model relates to the field of power Internet of Things (IoT) technology, and in particular to a fault monitoring device for a cabinet used in power IoT. Background Technology

[0002] The Internet of Things (IoT) in the power grid is the application of IoT in smart grids. It is a result of the development of information and communication technology to a certain stage. It will effectively integrate communication infrastructure resources and power system infrastructure resources, improve the informatization level of the power system, improve the utilization efficiency of existing power system infrastructure, and provide important technical support for the generation, transmission, transformation, distribution and consumption of electricity in the power grid.

[0003] Currently, when power IoT fault monitoring devices are in use, the wiring inside the cabinet may short-circuit after long-term use, potentially causing a fire. Furthermore, the device itself cannot extinguish the fire inside. To address these shortcomings, the monitoring device has been improved by allowing carbon dioxide from the inner cavity of the carbon dioxide tank to enter the inner cavity of the device itself, automatically extinguishing the fire and protecting the power IoT server. Additionally, the sealing baffle can be opened by staff, facilitating easy replacement of the carbon dioxide tank. This reduces the cost of the monitoring device while also improving its safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that after long-term use, the internal wiring of the cabinet may short-circuit and cause fire, and the device itself cannot extinguish the fire inside. To this end, we propose a fault monitoring device for cabinets applied to the Internet of Things of Power.

[0005] To achieve the above objectives, this application adopts the following technical solution: a fault monitoring device for a cabinet applied to the power Internet of Things, comprising a device body, a door rotatably connected to the surface of the device body via a hinge, a temperature sensor fixedly connected to the inner cavity of the device body, a storage box fixedly connected to the top of the device body, a carbon dioxide tank disposed in the inner cavity of the storage box, one end of the carbon dioxide tank being electrically connected to the temperature sensor, a sealing baffle slidably connected to the inner cavity of the storage box, a pull ring fixedly connected to the top of the sealing baffle, an adjusting housing fixedly connected to the top of the storage box, a limiting housing fixedly connected to the top of the sealing baffle, a connecting block slidably connected to the inner cavity of the adjusting housing, a connecting post fixedly connected to one end of the connecting block, fixing posts fixedly connected to both sides of the connecting block, a sliding plate slidably connected to the surface of the fixing post, limiting grooves formed on both sides of the limiting housing, a limiting block slidably connected to the inner cavity of the limiting groove, and a limiting block fixedly connected to the sliding plate at the end of the limiting block near the sliding plate.

[0006] Preferably, a first spring is fixedly connected to both sides of the connecting block, and the end of the first spring near the slider is fixedly connected to the slider.

[0007] Preferably, the adjusting housing has slots on both sides, and a hollow block is slidably connected to the inner diameter of the slot. The inner cavity of the hollow block is slidably connected to the surface of the fixed column.

[0008] Preferably, a second spring is fixedly connected to the inner cavity of the adjusting housing, and the end of the second spring near the connecting post is fixedly connected to the connecting post.

[0009] Preferably, a guide post is fixedly connected to the inner cavity of the device body, a square block is slidably connected to the surface of the guide post, a shelf is fixedly connected to the top of the square block, a limit bolt is slidably connected to the inner cavity of the shelf, and a limit hole is opened in the inner cavity of the device body, the inner cavity of the limit hole is adapted to the limit bolt.

[0010] Preferably, the inner cavity of the device body is provided with a guide groove, and a guide block is slidably connected to the inner cavity of the guide groove. The end of the guide block near the square block is fixedly connected to the square block.

[0011] Preferably, a third spring is fixedly connected to the inner cavity of the device body, and the end of the third spring near the square block is fixedly connected to the square block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when a fault occurs in the wiring or other components of the device body within the cabinet, causing the internal temperature of the device body to rise, the temperature sensor will automatically detect this. When the temperature reaches the critical point for the temperature sensor to activate, the carbon dioxide tank will open, allowing carbon dioxide from the tank to enter the internal cavity of the device body and automatically extinguish the fire within the device body, thus protecting the power IoT server. Furthermore, staff can open the sealing baffle, facilitating the replacement of the carbon dioxide tank at any time. This reduces the cost of the monitoring device while also improving the safety of the device body.

[0014] In this invention, the worker pulls the shelf outward, causing the shelf to slide the inner cavity of the square block on the surface of the guide post. At the same time, the square block causes the surface of the guide block to slide in the inner cavity of the guide groove. As the square block moves, it causes the third spring to stretch and store force. When the shelf moves a certain distance, the limiting bolt falls into the inner cavity of the limiting hole under the influence of gravity, thus limiting and fixing the shelf. Through the above structure, it is convenient for workers to inspect and maintain the power Internet of Things server and prevent the probability of line failure. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 3As shown, this utility model provides a technical solution: a fault monitoring device for a cabinet applied to the power Internet of Things, including a device body 1, a door 2 rotatably connected to the surface of the device body 1 via a hinge, a temperature sensor 3 fixedly connected to the inner cavity of the device body 1, a storage box 4 fixedly connected to the top of the device body 1, a carbon dioxide tank 5 disposed in the inner cavity of the storage box 4, one end of the carbon dioxide tank 5 being electrically connected to the temperature sensor 3, and a sealing baffle 6 slidably connected to the inner cavity of the storage box 4, the top of the sealing baffle 6... A pull ring 7 is fixedly connected to the end of the storage box 4. An adjusting housing 8 is fixedly connected to the top of the sealing baffle 6. A limiting housing 9 is fixedly connected to the top of the sealing baffle 6. A connecting block 10 is slidably connected to the inner cavity of the adjusting housing 8. A connecting post 11 is fixedly connected to one end of the connecting block 10. Fixed posts 12 are fixedly connected to both sides of the connecting block 10. A sliding piece 13 is slidably connected to the surface of the fixed post 12. Limiting grooves 14 are opened on both sides of the limiting housing 9. A limiting block 15 is slidably connected to the inner cavity of the limiting groove 14. The limiting block 15 is close to the sliding piece 13. One end is fixedly connected to the sliding plate 13. When a fault occurs in the wiring or other components inside the device body 1, causing the temperature inside the device body 1 to rise, the temperature sensor 3 will automatically sense this. When the temperature reaches the critical point for the temperature sensor 3 to activate, the temperature sensor 3 will open the carbon dioxide tank 5 through electrical connection, allowing carbon dioxide from the inner cavity of the carbon dioxide tank 5 to enter the inner cavity of the device body 1, automatically extinguishing the fire inside the device body 1 and protecting the power IoT server. Furthermore, the operator can open the sealing baffle 6. By pressing the hollow block 18, the operator moves the sliding plate 13, causing the surface of the limiting block 15 to gradually detach from the inner cavity of the limiting groove 14. At this point, the operator pulls the hollow block 18, causing the sliding plate 13 and the limiting block 15 to detach from the inner cavity of the limiting housing 9. The sealing baffle 6 will then be unrestrained and can be opened by the operator. This structure allows for convenient replacement of the carbon dioxide tank 5 by the operator, reducing the cost of the monitoring device and improving the safety of the device body 1.

[0022] Reference Figure 3 As shown in this embodiment: both sides of the connecting block 10 are fixedly connected with a first spring 16. The end of the first spring 16 near the slider 13 is fixedly connected to the slider 13. When the operator presses the hollow block 18, the hollow block 18 moves the slider 13 and at the same time squeezes the first spring 16 to store force. Through the above structure, the rebound force of the first spring 16 continuously pushes the slider 13 to reset, so that the slider 13 drives the surface of the limiting block 15 to engage and limit the limiting groove 14.

[0023] Reference Figure 3As shown in this embodiment: slots 17 are provided on both sides of the adjusting housing 8. A hollow block 18 is slidably connected to the inner diameter of the slot 17. The inner cavity of the hollow block 18 is slidably connected to the surface of the fixed column 12. When the operator pulls the hollow block 18, the hollow block 18 slides in the inner cavity of the slot 17. Through the above structure, the connecting block 10 maintains directional displacement when it is displaced, preventing the connecting block 10 from shifting and affecting the coordination between the structures.

[0024] Reference Figure 3 As shown in this embodiment: a second spring 19 is fixedly connected to the inner cavity of the adjusting housing 8. The end of the second spring 19 near the connecting column 11 is fixedly connected to the connecting column 11. When the operator pulls the hollow block 18, the hollow block 18 causes the connecting block 10 and the connecting column 11 to move, causing the connecting column 11 to squeeze the second spring 19 to store force. Through the setting of the second spring 19, the rebound force of the second spring 19 continuously pushes the connecting block 10 to reset, further improving the linkage between the structures.

[0025] Reference Figure 1 and Figure 4 As shown in this embodiment: a guide post 20 is fixedly connected to the inner cavity of the device body 1, a square block 21 is slidably connected to the surface of the guide post 20, a shelf 22 is fixedly connected to the top of the square block 21, a limit bolt 23 is slidably connected to the inner cavity of the shelf 22, and a limit hole 24 is opened in the inner cavity of the device body 1. The inner cavity of the limit hole 24 is adapted to the limit bolt 23. When the staff needs to pull the IoT server for maintenance, the staff pulls the shelf 22 outward, causing the shelf 22 to move the square block 21. The inner cavity slides on the surface of the guide post 20, while the square block 21 drives the surface of the guide block 26 to slide in the inner cavity of the guide groove 25. As the square block 21 moves, the square block 21 drives the third spring 27 to stretch and store force. When the placement plate 22 moves a certain distance, the limiting bolt 23 falls into the inner cavity of the limiting hole 24 under the influence of gravity, and limits and fixes the placement plate 22. Through the above structure, it is convenient for staff to inspect and maintain the power Internet of Things server and prevent the probability of line failure.

[0026] Reference Figure 4 As shown in this embodiment: the inner cavity of the device body 1 is provided with a guide groove 25, and a guide block 26 is slidably connected to the inner cavity of the guide groove 25. The end of the guide block 26 near the square block 21 is fixedly connected to the square block 21. When the operator pulls the placement plate 22, the placement plate 22 causes the square block 21 to move. At the same time, the square block 21 causes the surface of the guide block 26 to slide in the inner cavity of the guide groove 25. Through the above structure, the square block 21 maintains directional displacement when it moves.

[0027] Reference Figure 4As shown in this embodiment: a third spring 27 is fixedly connected to the inner cavity of the device body 1. The end of the third spring 27 near the square block 21 is fixedly connected to the square block 21. When the operator pulls the placement plate 22, the placement plate 22 moves the square block 21, and at the same time stretches the third spring 27 to store force. Through the above structure, the rebound force of the third spring 27 continuously drives the square block 21 and the placement plate 22 to reset, and at the same time drives the IoT server to reset, which facilitates the normal use of the IoT server.

[0028] Working principle: When the temperature rises due to a circuit fault in the inner cavity of the device body 1, the temperature sensor 3 will automatically sense it. When the temperature reaches the critical point for activation of the temperature sensor 3, the temperature sensor 3 will open the carbon dioxide tank 5 through electrical connection, allowing carbon dioxide in the inner cavity of the carbon dioxide tank 5 to enter the inner cavity of the device body 1, automatically extinguishing the fire in the inner cavity of the device body 1, while protecting the power IoT server. At the same time, the operator can open the sealing baffle 6. By pressing the hollow block 18, the operator moves the sliding plate 13, causing the surface of the limiting block 15 to gradually disengage from the inner cavity of the limiting groove 14. Then, the operator pulls the hollow block 18, causing the sliding plate 13 and the limiting block 15 to disengage from the inner cavity of the limiting housing 9. At this point, the sealing baffle 6 will be unrestrained and can be opened by the operator. The aforementioned structure facilitates easy replacement of the carbon dioxide tank 5 by staff, while also reducing the cost of the monitoring device and improving the safety of the device body 1. When staff need to pull the IoT server for maintenance, they pull the placement plate 22 outward, causing the inner cavity of the square block 21 to slide on the surface of the guide post 20. Simultaneously, the square block 21 causes the surface of the guide block 26 to slide in the inner cavity of the guide groove 25. As the square block 21 moves, it causes the third spring 27 to stretch and store force. When the placement plate 22 moves a certain distance, the limiting bolt 23 falls into the inner cavity of the limiting hole 24 under the influence of gravity, thus limiting and fixing the placement plate 22. Through the above structure, staff can easily carry out maintenance and repair of the power IoT server, reducing the probability of line failure.
