Description

Technical Field

[0001] The utility model relates to the field of ring network cabinets, in particular to an over-temperature automatic alarm ring network cabinet. Background Art

[0002] Ring main unit is a group of electrical transmission and distribution equipment, which is an electrical equipment in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] There are mainly two types of existing ring network cabinets. One is an open airflow ring network cabinet, which has a good heat dissipation effect, but the ring network cabinet cannot be installed with effective fire extinguishing means. The other closed ring network cabinet, although it can extinguish fires well, requires additional installation of electric heat dissipation devices for effective heat dissipation, which increases the installation cost of the ring network cabinet. Therefore, when performing the ring network cabinet, it is necessary to provide a new type of over-temperature automatic alarm ring network cabinet. The heat dissipation port is in an open state under normal temperature, and when spontaneous combustion occurs, the ring network cabinet can be quickly closed to facilitate the subsequent inert gas inflow and outflow, so as to achieve the benefit of better fire extinguishing. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an over-temperature automatic alarm ring network cabinet to solve the technical problem that the practicality of the traditional ring network cabinet needs to be improved.

[0005] To achieve the above object, the utility model provides the following technical solutions: an over-temperature automatic alarm ring network cabinet, comprising a cabinet body, heat dissipation ports are arranged on both sides of the cabinet body, and heat dissipation holes are arranged at the bottom of the heat dissipation ports;

[0006] A closing mechanism is provided below the inner wall of the cabinet, and the closing mechanism comprises an electric push rod, and an output end of the electric push rod is detachably connected to a connecting frame;

[0007] Two racks are arranged on both sides of the connecting frame, a rotating rod is arranged on the inner side of the heat dissipation opening, and the rotating rod is rotatably connected to the cabinet body;

[0008] The rotating rod is provided with two gears, and the gears are meshed with the racks;

[0009] A sealing plate is arranged on the inner side of the two gears, and the sealing plate is used to cover the heat dissipation holes so that the inner wall of the cabinet is in a closed state.

[0010] By adopting the above technical solution, good ventilation and heat dissipation inside the cabinet are effectively guaranteed through the heat dissipation ports and heat dissipation holes, thus preventing the equipment from being damaged due to overheating, improving the operating stability and life of the equipment, and the setting of the closing mechanism can close the inside of the cabinet when necessary to prevent the spread of fire or the influence of adverse external environment, thereby enhancing the safety of the equipment.

[0011] Furthermore, the sealing plate is made of a rubber sheet, and a plurality of the sealing plates are provided, and the number of the plurality of sealing plates is the same as the number of the heat dissipation ports.

[0012] By adopting the above technical solution, the rubber sealing plate has good elasticity and sealing performance, which can ensure that it fits tightly to the heat dissipation hole when closed, effectively isolating the air circulation, and the number of multiple sealing plates is the same as the heat dissipation port, ensuring that each heat dissipation port can be effectively closed, thereby improving the overall sealing effect.

[0013] Furthermore, an environmental sensor is arranged in the middle of the inner wall of the cabinet, and the environmental sensor includes a temperature sensor and a humidity sensor. The temperature sensor is used to sense the temperature of the cabinet, and the humidity sensor is used to sense the humidity of the cabinet.

[0014] By adopting the above technical solution, the temperature sensor can monitor the internal temperature of the cabinet in real time, detect abnormal temperature rise in time, and prevent equipment overheating failure. The humidity sensor can monitor the humidity level inside the cabinet to prevent excessive humidity from causing equipment corrosion or electrical performance degradation.

[0015] Furthermore, an air jet is arranged above the inner wall of the cabinet, and two air jets are arranged in a mirror image along the width center line of the cabinet.

[0016] By adopting the above technical solution, the two jet ports ensure that fire-extinguishing gas can be quickly released into the cabinet in an emergency, covering a wider area. The mirrored setting along the center line of the cabinet width ensures uniform gas distribution and improves fire-extinguishing efficiency.

[0017] Furthermore, an air duct is provided on one side of the air jet port, and the air duct is connected to an external inert gas tank.

[0018] By adopting the above technical solution, the connection of the gas pipe ensures a stable supply of fire-extinguishing gas, and the fire-extinguishing mechanism can be quickly activated when needed. In addition, the connection with the external inert gas tank ensures that the ring network cabinet has sufficient fire-extinguishing gas reserves when operating independently, thereby enhancing the autonomous fire-fighting capability.

[0019] Furthermore, a sound outlet is provided on one side of the cabinet, and the sound outlet is used to indicate a fire problem inside the cabinet.

[0020] By adopting the above technical solution, the sound outlet can promptly sound an alarm when an internal fire is detected, alerting people around to take emergency measures.

[0022] By adopting the above technical solution, the visual window allows the user to observe the status of the equipment inside the cabinet without opening the cabinet door, which is convenient for daily inspection and maintenance. In addition, the visual window can promptly detect signs of equipment abnormality or failure, and take measures in advance to avoid the problem from escalating.

[0023] Furthermore, a cabinet lock is provided on one side of the viewing window, and the cabinet lock is used to lock the cabinet body and the cabinet door.

[0024] By adopting the above technical solution, the setting of the cabinet lock ensures that the cabinet body and the cabinet door are tightly locked, preventing unauthorized personnel from opening the cabinet door at will, improving the safety of the equipment, and the cabinet lock can effectively protect the internal equipment from external adverse environment or accidental damage.

[0025] Furthermore, a handle is provided above the heat dissipation port, and two handles are provided, and the two handles are mirror-imaged along the width center line of the cabinet.

[0026] By adopting the above technical solution, the two handles make it more convenient and labor-saving for users to open the cabinet door, and the handles mirrored along the center line of the cabinet width conform to ergonomic principles, making them more comfortable and natural to use.

[0027] Furthermore, an electric device is arranged inside the cabinet, and a wiring opening is provided at the bottom of the cabinet. The wiring opening is used to install a circuit line and ensure that the circuit line is connected to the electric device.

[0028] By adopting the above technical solution, the setting of the power device enables the ring main unit to have power distribution and management functions, meeting the operation requirements of the power system. The wiring opening facilitates the installation and wiring of the circuit line, while ensuring the reliable connection between the circuit line and the power device.

[0029] In summary, the utility model mainly has the following beneficial effects:

[0030] 1. The utility model sets a sealing mechanism. When the environmental sensor detects that the humidity inside the cabinet is too high or the temperature sensor detects an abnormally high temperature, it means that the electrical device inside the cabinet is on fire. At this time, the electric push rod starts to work and pushes the rack to move through the connecting frame. Then the movement of the rack drives the gear meshing with it to rotate, thereby causing the rotating rod to rotate, and then the sealing plate on the rotating rod moves accordingly to cover the heat dissipation hole, so that the inside of the cabinet is closed. After the cabinet is closed, the inert gas released from the jet port can fill the entire space more quickly to reach the concentration required for fire extinguishing. In contrast, in the state of air circulation, the fire extinguishing gas may be quickly diluted or blown away, thereby reducing its fire extinguishing effect, and the closed environment helps to limit the supply of oxygen, thereby controlling the fire. In the state of air circulation, oxygen may be continuously replenished to the fire source, exacerbating the spread of the fire. In addition, using a gas fire extinguishing device in a closed environment can reduce the risk of fire extinguishing gas leaking to the external environment and avoid unnecessary harm to personnel and the environment. On the contrary, in the state of air circulation, the fire extinguishing gas may leak to adjacent areas, causing greater safety risks.

[0031] 2. The utility model is provided with an environmental sensor, an air jet and a sound outlet. The setting of the environmental sensor enables the cabinet to have the ability to monitor the internal temperature and humidity in real time, and the two air jets ensure the uniform and rapid distribution of the fire extinguishing gas in an emergency. The two air jets are mirrored along the width center line of the cabinet, so that the gas can quickly fill the entire cabinet to achieve the effect of rapid fire extinguishing. The setting of the sound outlet enables the ring network cabinet to immediately sound an alarm when an internal fire is detected, reminding the surrounding personnel to pay attention and take corresponding measures.
