Description

Technical Field

[0001] The invention relates to the technical field of metering cabinets, in particular to a multifunctional electric power metering cabinet. Background Art

[0002] The meter cabinet contains a number of measuring and metering devices, such as watt-hour meters, ammeters, voltmeters, and power factor meters. For the electric energy metering devices installed at the user's location, the user is responsible for protecting the seals. When a fault is found in the electric energy metering device, the electric energy metering technical organization should be notified in a timely manner for processing.

[0003] The traditional power meter cabinet has a simple overall structure and a single heat dissipation method. Since the power meter cabinet generates heat during the operation of internal components, when the cooling fans on both sides fail or the components fail, heat is easily accumulated inside the power meter cabinet, which further causes other components to work at high temperatures. When other normal components work at high temperatures, they are prone to work abnormally in a high temperature environment, resulting in large-scale component failures, resulting in a vicious cycle, and even possible component burning and fire. When these phenomena occur, they are difficult to detect in time, so the power meter cabinet is easily burned, and internal components and data are lost, causing losses. In view of the shortcomings of the prior art, the present invention provides a multifunctional power meter cabinet to solve the above problems. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a multifunctional electric power metering cabinet, which adopts a temperature sensor body and a smoke sensor body to safely monitor the internal operating environment of the metering cabinet body, and also uses a camera body to safely monitor the internal operating environment of the metering cabinet body. When an abnormal signal is detected, it is reported in time, and an alarm is issued for timely maintenance to ensure that the internal operating environment of the metering cabinet body is stable. When the temperature sensor body detects that the temperature rises and is within the normal range, the controller drives the external enhanced cooling fan to work to enhance the heat dissipation function. When the smoke sensor body detects smoke information, the controller immediately stops the external enhanced cooling fan and drives the electric-controlled fire extinguisher to work, providing fire fighting and fire extinguishing functions to reduce losses. Through the design of connecting pipes and connecting ring pipes, in the process of enhanced heat dissipation and fire extinguishing, heat dissipation and fire fighting are provided to the interior of the metering cabinet body from multiple angles to ensure that the heat dissipation and fire fighting functions are effective, so that the device functions stably, protects data and components, and meets usage requirements.

[0036] The embodiment of the present application provides a multifunctional power meter cabinet to solve the problems of the traditional power meter cabinet having a simple overall structure and a single heat dissipation method. Since the power meter cabinet generates heat during the operation of the internal components, when the cooling fans on both sides fail or the components fail, heat is easily accumulated inside the power meter cabinet, which further causes other components to work at high temperatures. When other normal components work at high temperatures, they are prone to work abnormally in a high temperature environment, causing large-scale component failures, resulting in a vicious cycle, and even possible component burning and fire. When these phenomena occur, they are difficult to detect in time, so the power meter cabinet is easily burned, and internal components and data are lost, causing losses.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The embodiment of the present invention discloses a multifunctional electric power metering cabinet.

[0047] Furthermore, an air inlet pipe 702 is provided on the top of the external enhanced cooling fan 7, and a second filter 703 is movably connected inside the air inlet pipe 702.

The second filter 703 is connected between the air inlet pipe 702 and the threaded ring 704, and the threaded ring 704 is easy to disassemble and assemble, thereby making the second filter 703 easy to disassemble, assemble, clean and maintain.

[0048] Furthermore, a one-way valve 1001 is provided on the fixed pipe seat 10. The one-way valve 1001 is convenient for the airflow generated by the external enhanced cooling fan 7 to enter the connecting ring pipe 3 and the connecting pipe 2 through the fixed pipe seat 10 when the heat dissipation is enhanced.

[0050] Working principle: The multifunctional electric power metering cabinet uses a temperature sensor body 503 and a smoke sensor body 504 to monitor the internal operating environment safety of the metering cabinet body 1;

[0051] When the temperature sensor body 503 detects that the temperature rises and is within the normal range, the controller 5 drives the external enhanced heat dissipation fan 7 to work, and the external enhanced heat dissipation fan 7 blows the external air into the butt joint pipe 701, enters the interior of the fixed pipe seat 10 and the connecting ring pipe 3 from the butt joint pipe 701, and finally passes through the multiple groups of connecting pipes 2 into the inner cavity of the metering cabinet body 1, providing enhanced heat dissipation for the interior of the metering cabinet body 1 at multiple angles;

[0052] When the smoke sensor body 504 detects smoke information, the controller 5 immediately stops the external enhanced cooling fan 7 and drives the electronically controlled fire extinguisher 6 to work, and uses the fire sprinkler solenoid valve 501 to spray the firefighting medium. The firefighting medium enters the interior of the connecting ring pipe 3 through the installation docking seat 4, and then enters the interior of the metering cabinet body 1 through multiple groups of connecting pipes 2, providing fire extinguishing for the interior of the metering cabinet body 1 from multiple angles, reducing the loss of components inside the metering cabinet;

[0053] The electric fire extinguisher 6 and the controller 5 are convenient to be disassembled and assembled on the mounting docking seat 4. During the disassembly and assembly process, the external enhanced cooling fan 7 is simultaneously disassembled and assembled, so that the external enhanced cooling fan 7, the electric fire extinguisher 6 and the controller 5 are easy to maintain. When the electric fire extinguisher 6 and the controller 5 are installed and positioned, the positioning plug 8 is directly aligned with the inside of the positioning sleeve 9 and inserted;

[0054] When the positioning pin 8 is aligned with the positioning sleeve 9 and inserted into the interior, the positioning pin 8 contacts and squeezes the inclined surface of the wedge block 903, and the positioning pin 8 pushes the wedge block 903 to push horizontally, and the wedge block 903 drives the sliding column 902 to move and squeeze the spring 904. When the positioning pin 8 is fully inserted into the interior of the positioning sleeve 9, the position of the wedge block 903 is aligned with the locking groove 801. At this time, the spring 904 stretches and pushes the sliding column 902 and the wedge block 903 to move, so that the wedge block 903 is inserted into the interior of the locking groove 801, thereby locking the position of the positioning pin 8 and the positioning sleeve 9, and then locking the electric fire extinguisher 6 and the controller 5 after being clamped on the installation docking seat 4, and also locking the docking pipe 701 after it is inserted into the interior of the fixed pipe seat 10;

[0055] When it is necessary to unlock the positioning pin 8 and the positioning sleeve 9 and disassemble the external enhanced cooling fan 7, the electric fire extinguisher 6 and the controller 5, it is only necessary to pull the unlocking handle 905 to move the sliding column 902 and the wedge block 903 as a whole and squeeze the spring 904 to disengage the wedge block 903 from the locking groove 801, thereby unlocking the positioning pin 8 and the positioning sleeve 9, and then disassembling the external enhanced cooling fan 7, the electric fire extinguisher 6 and the controller 5. The operation is simple and convenient, saving time and effort.

[0056] In summary, the multifunctional electric power metering cabinet adopts the temperature sensor body 503 and the smoke sensor body 504 to monitor the safety of the internal operating environment of the metering cabinet body 1, and also uses the camera body 502 to monitor the safety of the internal operating environment of the metering cabinet body 1. When an abnormal signal is detected, it is reported in time, and an alarm is issued for timely maintenance to ensure that the internal operating environment of the metering cabinet body 1 is stable. When the temperature sensor body 503 detects that the temperature rises and is within the normal range, the controller 5 drives the external enhanced cooling fan 7 to work to enhance the heat dissipation function. When the smoke sensor body 504 detects smoke information, the controller 5 immediately stops the external enhanced cooling fan 7 and drives the electric fire extinguisher 6 to work, providing fire fighting and fire extinguishing functions to reduce losses. Through the design of the connecting pipe 2 and the connecting ring pipe 3, in the process of strengthening heat dissipation and fire extinguishing, heat dissipation and fire fighting are provided to the interior of the metering cabinet body 1 from multiple angles to ensure that the heat dissipation and fire fighting functions are effective, so that the device functions stably, protects data and components, and meets usage requirements.
