Description

Technical Field

[0001] The invention relates to the technical field of electric meters, in particular to an assembled electric meter provided with an overheat protection mechanism. Background Art

[0002] An electric meter is an instrument used to measure electrical energy consumption and is usually installed in homes, businesses, and industries. It can record electricity consumption, help users understand electricity usage and calculate costs accordingly;

[0003] During the use of the electric meter, a certain amount of heat will be generated due to the current flowing inside it. If the heat is not dissipated in time, the high temperature will cause damage to the electric meter, thus affecting the service life of the electric meter.

[0004] To solve the above problems, a Chinese patent with announcement number CN108872662A (application date 2018-09-06) in the prior art discloses a heat dissipation meter box, in which connecting ribs divide the cavity formed by the outer baffle and the inner baffle into multiple airflow channels, the upper end of the airflow channel is connected to the internal space of the box, and an air collecting shell is arranged at the lower end of the airflow channel. An exhaust fan and an air outlet are fixedly arranged in the air collecting shell, and an air inlet is arranged on the bottom plate. The air flow mode of bottom-in and bottom-out is adopted, which solves the problems of wind blocking and rainwater intrusion in the prior art, and the whole airflow fully utilizes the rising buoyancy of the hot air generated by the electric energy meter in the process of penetrating the entire space in the box from bottom to top, thereby improving the flow efficiency of the gas in the box.

[0005] For example, a Chinese patent with announcement number CN112904063A (application date 2021-01-29) in the prior art discloses a heat dissipation meter box, wherein a heat dissipation backplate is provided between the box bodies, and an array of heat dissipation holes is provided on the heat dissipation backplate, a mounting plate is provided on the inside of the box body, a cabinet door mounting plate is provided on the mounting plate, a top cover is provided at the upper end of the box body, a first mounting frame is provided in the box body, a second mounting frame is provided on one side of the first mounting frame, a lower box plate is provided at the lower end of the box body, a heat dissipation mechanism is provided under the lower box plate, the second mounting frame divides one side of the first mounting frame into two parts, a first partition plate is provided on the inner side of the second mounting frame, a ventilation groove and a first wire groove are provided on the partition plate, and an air inlet is provided on the lower box plate, which is beneficial to the heat dissipation of the meter in the box, ensures the stable and reliable operation of the meter, helps to reduce meter failures, and avoids inconvenience to users.

[0006] Combined with the above materials, it can be known that the prior art at most adopts fan heat dissipation to achieve the purpose of overheating protection of the electric meter. However, in actual use, the fan heat dissipation is greatly affected by the temperature of the external environment. For example, in summer, the outside air temperature is high, and the air takes away less heat when flowing, so the heat dissipation effect is poor. At this time, when the power of the electric meter is high, overheating will still occur. Summary of the invention

[0040] When using the device, first use the fixing plate 3 to fix the outer box body 1 of the meter on the wall, then open the protective cover 2 and put the independent meter 5 into the outer box body 1 of the meter. At this time, the mounting groove 501 at the rear of the independent meter 5 is inserted into the mounting plate 4, and at the same time, the locking grooves 502 on the upper and lower sides of the mounting groove 501 and the locking strips 401 on the upper and lower sides of the mounting plate 4 are locked and fixed to each other.

A stirring rod 14 for stirring the coolant is rotatably installed in the middle position inside the storage box 10, and the stirring rod 14 is driven to rotate by a driving motor 15 fixedly installed inside the outer box body 1 of the electric meter. The lifting mechanism includes a connecting slider 18 installed on the outside of the movable plate 16, and a vibration spring 19 is fixedly installed between the connecting slider 18 and the movable plate 16. A transmission screw 20 is threadedly installed inside the connecting slider 18 to drive it to move up and down, and a driven bevel gear 21 is coaxially fixedly installed on the top of the transmission screw 20, and a driving bevel gear 22 is meshed and connected above the driven bevel gear 21, a driven roller 23 that rotates synchronously with the driving bevel gear 22 is fixedly installed on the side of the driving bevel gear 22, and a driving roller 24 that fits and rubs against the driven roller 23 is arranged above the driven roller 23, and the driving roller 24 and the stirring rod 14 are coaxially fixedly installed.

[0042] When the device is in normal use, the temperature sensor 9 on the outer surface of the mounting plate 4 is used to monitor the temperature of the independent electric meter 5 in real time. When the temperature reaches the preset setting, the temperature sensor 9 notifies the controller 11 through a Bluetooth signal. At this time, the controller 11 starts the delivery pump 12, and uses the delivery pump 12 to deliver the coolant in the storage box 10 to the water cooling pipe 8. At this time, the water cooling pipe 8 and the heat conducting plate 7 fixedly installed on the back of the independent electric meter 5 are used to exchange heat with each other to enhance heat dissipation, thereby quickly cooling the independent electric meter 5 to achieve the purpose of overheating protection. At the same time, the semiconductor refrigeration plate 13 inside the storage box 10 is turned on, and the semiconductor refrigeration plate 13 is used to cool the coolant inside the storage box 10, thereby ensuring the heat exchange effect of the coolant. At this time, the drive motor 15 is turned on, and the drive motor 15 is used to drive the stirring rod inside the storage box 10 14 rotates, so that the stirring rod 14 stirs the coolant in the storage box 10, thereby improving the cooling effect of the semiconductor refrigeration plate 13 on the coolant. During the rotation of the stirring rod 14, the active roller 24 coaxially fixed therewith is driven to rotate. At this time, the friction force on the surface of the active roller 24 is used to drive the driven roller 23 to rotate. During the rotation of the driven roller 23, the active bevel gear 22 is driven to rotate. At this time, the driven bevel gear 21 meshing with the active bevel gear 22 drives the transmission screw 20 to rotate.

[0044] When the device is in normal use, the electromagnet 27 is turned on, and the connecting plate 26 is fixedly adsorbed in a horizontal position by the magnetic adsorption effect of the electromagnet 27. Then, the power supply of the electromagnet 27 is periodically turned off. At this time, the electromagnet 27 loses its adsorption effect on the connecting plate 26, and the connecting plate 26 is driven to rotate upward under the elastic pulling effect of the connecting spring 29. The knocking block 28 on the upper surface of the connecting plate 26 is used to knock the movable plate 16, so that the movable plate 16 vibrates, so as to achieve the purpose of cleaning the dust accumulated at the position of the air inlet slot 17.
