Description

Technical Field

[0001] The utility model relates to the field of intelligent electric meters, in particular to an intelligent electric meter with a load intelligent identification function. Background Art

[0002] The electricity management of campus apartments or dormitories is a very important part of the logistics management system, and safe electricity use is closely related to students' life and study. With the rapid development of my country's economy, the accommodation environment on campus is also keeping pace with the times. High-power electrical appliances such as air conditioners and televisions are gradually entering the campus. Therefore, the issue of safe electricity use in campus apartments and dormitories has received more and more attention. Most students are not aware of the safe use of electricity, and the population density of campus apartments and dormitories is very high. Students will have peak electricity use when they are in the dormitory. They will turn on electrical equipment at the same time and even use prohibited electrical appliances. In this case, it is very easy to cause overload of power lines and cause the whole building to trip and power outage or even cause a fire. Therefore, a smart meter with load intelligent identification function is provided on the market.

[0003] According to the public patent 202021147103.8, a smart meter with malicious load identification and control functions includes an MCU module and a power supply module, a sampling detection module, a display module, a control module and a central platform electrically connected to the MCU module, respectively. The central platform includes a communication module, a concentrator and a GPRS module. The MCU module determines the input feedback signal and outputs a control signal to control the power consumption, and reports information to the central platform to prompt the staff. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Through the setting of the central platform, the information of the malicious load is fed back to the management end in time, which is convenient for the management personnel to respond in time, and the management personnel's workflow is simplified to solve the problem that the smart meter cannot identify the load. During use, the traditional smart meter cannot automatically extinguish the fire in the wiring trough. The wire in the wiring trough catches fire and easily causes damage to the smart meter, which reduces the safety of the smart meter during use. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a smart meter with a load intelligent identification function to solve the technical problems that the current smart meter cannot automatically extinguish fires in the wiring trough and the safety of the smart meter is relatively low during use.

[0006] Preferably, the locking bolt passes through the interior of the connecting plate and is connected to the interior of the threaded hole via threads.

[0007] Preferably, one side of the sealing baffle is attached to the inner side of the protective cover and covers the outside of the through groove, one end of the electric push rod is fixedly connected to the bottom of the sealing baffle, and the other end of the electric push rod is fixedly connected to the bottom of the protective cover.

[0008] Preferably, one end of the air duct passes through the interior of the storage box and is sealed to the air outlet end of the blower, and the other end of the air duct corresponds to the position of the through slot.

[0009] Preferably, both ends of the stirring mechanism are rotatably connected to the inner wall of the storage box, and the bottom of the storage box is sloped.

[0025] A through groove 17 is provided on one side of the outside of the protective cover 15, and a sealing baffle 18 is slidably connected to one side of the through groove 17. An electric push rod 19 is installed at the bottom of the sealing baffle 18, and one side of the sealing baffle 18 is attached to the inner side of the protective cover 15 and covers the outside of the through groove 17. One end of the electric push rod 19 is fixedly connected to the bottom of the sealing baffle 18, and the other end of the electric push rod 19 is fixedly connected to the bottom of the protective cover 15. A storage box 20 is sealedly connected to one side of the protective cover 15, and a plurality of blowers 21 are sealedly connected to one side of the storage box 20. The air inlet end of the blower 21 is sealed with a solenoid valve 22, and an air duct 23 is installed at the air outlet end of the blower 21. One end of the air duct 23 passes through the interior of the storage box 20 and is sealed to the air outlet end of the blower 21, and the other end of the air duct 23 corresponds to the position of the through groove 26. A driving motor 24 is fixedly connected to one end of the outside of the storage box 20. The output end of the driving motor 24 is fixedly connected with a stirring mechanism 25, and the two ends of the stirring mechanism 25 are rotatably connected to the inner wall of the storage box 20. The bottom of the storage box 20 is sloped, and a through slot 26 of the same size as the through slot 17 is opened on one side of the storage box 20. When a fire occurs in the wiring slot 11, the smoke sensor 12 transmits the received information to the controller 3, and the controller 3 controls the solenoid valve 22 to open, and controls the blower 21, the driving motor 24 and the electric push rod 19 to operate. At this time, the driving motor 24 drives the stirring mechanism 25 to stir the dry powder in the storage box 20, and the blower 21 blows the dry powder from the through slot 26 and the through slot 17 into the interior of the wiring slot 11 through the air duct 23, so as to achieve the fire extinguishing treatment in the wiring slot 11 of the smart meter, avoiding the phenomenon that the wire in the wiring slot 11 is caught on fire and the smart meter is damaged, thereby improving the safety of the smart meter during use;

[0026] Since the driving motor 24 drives the stirring mechanism 25 to rotate, it is possible to prevent the dry powder in the storage box 20 from being agglomerated and unable to be blown out due to long-term storage;

[0027] The electric push rod 19 will drive the sealing baffle 18 to move downward, so that the sealing baffle 18 is separated from the through groove 17, so that the through groove 17 is in a transparent state, so that the dry powder in the storage box 20 can enter the wiring groove 11.

The power supply module 32 is used for power supply. A load current limit value is set in advance in the central platform 34. The central platform 34 sends the limit value to the MCU module 31. When the sampling detection module 33 detects that the load current in the circuit is greater than the limit value, a feedback signal is sent to the MCU module 31. The MCU module 31 determines whether it is a malicious load. If it is, the MCU module 31 outputs an alarm signal, and the signal reaches the control coil of the relay 36. The relay 36 disconnects the circuit. At the same time, the MCU module 31 reports the information to the central platform 34, and prompts the dormitory management staff at the management end through the central platform 34 so that the dormitory management staff can respond quickly. After verifying that there is no problem with the inspection line, an instruction is issued through the central platform 34 to use power recovery.
