Description

Technical Field

[0001] The invention belongs to the technical field of electric energy metering boxes, and in particular relates to an electric energy metering box with a dustproof mechanism. Background Art

[0002] The power meter box is a device used to monitor and measure the use of electric energy, usually installed in the power system of buildings or industrial facilities. With the continuous development of the power system and the growth of electricity demand, the measurement and monitoring of electric energy has become increasingly important. Traditionally, electric energy metering is carried out through mechanical electric energy meters, but this method has problems such as low accuracy and difficult maintenance. Therefore, with the advancement of science and technology, the electric energy meter box has emerged as a new type of electric energy metering equipment. The electric energy meter box usually consists of an electric energy meter, a metering controller, a communication module, a power management module, etc. It can monitor the use of electric energy in real time and transmit relevant data to the central system or monitoring platform for remote management and control. Through the electric energy meter box, power suppliers can more accurately measure the user's electric energy usage, realize accurate billing and effective management of power resources. In general, as an important part of the modern power system, the electric energy meter box provides the power industry with solutions for accurate measurement, intelligent monitoring and remote management, and promotes the effective use of power resources and the sustainable development of energy management.

[0003] Dust isolation is an extremely important protection measure for the electricity meter box during use. The existing electricity meter box is often disturbed by dust during use, and is usually isolated with a dustproof net. Due to the invasion of external dust, the isolation effect gradually deteriorates after long-term use, causing internal electrical appliances to be invaded by dust, resulting in internal electrical appliance damage and short circuit. At the same time, when cleaning the dust, it is usually replaced by direct disassembly, so that the dust on the dustproof net will cause dust to fly during the processing process, causing dust to float to the internal electrical appliances over a large area. Not only is the dust not completely controlled, but the isolated dust will also float to the inside in a large area, resulting in an increase in internal dust, so that the isolation effect obtained in the dust isolation process is the opposite, which greatly reduces the safety of the electricity meter box. Summary of the invention

Specifically, the internal components of the electric energy meter box are first connected to the input circuit through an external power supply, and then the current transformer, voltage transformer and display device are connected through the metering integrated circuit, so that the current transformer and voltage transformer collect current and voltage signals, and output digital signals after being processed by the signal processing circuit. The metering integrated circuit receives these digital signals for calculation, and the final result is displayed through the display device, so as to realize accurate measurement and statistics of electric energy, thereby completing the working process of the electric energy meter box.

[0009] Through the above technical scheme, when in use, during the long-term operation of the electric energy meter box, external dust will invade the interior of the box. The dust-proof belt is attached to the two internal partitions to form a closed space with the internal structure to prevent dust from entering the interior and interfering with the normal working process inside the electric energy meter box. After a long period of protection, the dust-proof belt is used to remove dust from the dust-proof belt, so that the internal dust removal effect can be kept stable. Specifically, the first motor at the rear end of the internal partition is started to drive the dust removal roller to rotate. When the first synchronous wheel, the synchronous belt and the second synchronous wheel are connected, one of the conveying rollers can be driven to rotate. The first gear and the second gear are meshed to make the other conveyor roller rotate. The two conveyor rollers will drive the dustproof belt to be squeezed and transmitted in one direction, and the dustproof belt is rotated in one direction, so that the dustproof belt can be completely dusted by the dust removal roller. Then the fan is started to extract the removed dust. The airflow enters from the hole on the other side of the dust removal box to remove the fallen dust from the exhaust pipe and then is discharged from the air outlet pipe outside the box. At this point, the dust removal process of the dustproof belt is completed, so that the dust accumulated in the dustproof belt for a long time can be removed, making the subsequent dust prevention effect stronger and more convenient to clean.

[0010] Furthermore, the bonding mechanism includes a second motor fixedly connected to the rear end of the box body, the output end of the second motor is fixedly connected to the first driving shaft, the outer wall of the first driving shaft is fixedly connected to a rotating block, the four corners of the rotating block are rotatably connected to connecting rods, a plurality of sliding grooves are opened inside the internal partition, the other ends of the plurality of connecting rods are rotatably connected to auxiliary rollers, a plurality of movable connecting grooves are opened at the rear end of the sub-plate, the outer walls of the auxiliary rollers are slidably connected to the corresponding sliding grooves, and the plurality of movable connecting grooves are movably connected to the corresponding auxiliary rollers.

[0011] Through the above technical scheme, when in use, after moving the front cover plate and then placing the dustproof belt on the two partition boards, the fitting mechanism is used to completely fit the dustproof belt on the partition boards to prevent the dustproof belt from lifting up, allowing dust to enter the box body and cause internal safety hazards. Specifically, first move the front cover plate, then put the dustproof belt on the two partition boards and cover the front cover plate, start the second motor at the rear end of the box body to drive the rotating block on the outer wall of the first drive shaft, so that multiple connecting rods rotate in one direction, and when the front cover plate is closed, multiple auxiliary rollers remain inclined, and then under the rotation of the rotating block, multiple auxiliary rollers slide along the corresponding slide grooves, so that the dustproof belt can be pressed along the partition board until the dustproof belt can be completely fitted, so that the dustproof belt can completely isolate the external dust, greatly improve the dustproof effect, and reduce safety hazards.

[0012] Furthermore, the tightening mechanism includes a tightening box fixedly connected to the top of the inner wall of the box body, the tightening box, the rear end of the sub-plate is fixedly connected to the second box cover, the top of the tightening box is provided with two second notches, the rear end of the box body is fixedly connected to two fixed blocks, one side of one of the fixed blocks is fixedly connected to the third motor, the output end of the third motor is fixedly connected to a reverse threaded rod, the outer wall of the reverse threaded rod is rotatably connected to two movable blocks, the front ends of the two movable blocks are rotatably connected to movable rods, and the other ends of the two movable rods are rotatably connected to extrusion rollers, the rear end of the tightening box is provided with two arc grooves, the rear end of the second box cover is movably connected to the tightening box, the inside of the two second notches is slidably connected to the dustproof belt, the outer wall of the reverse threaded rod is rotatably connected to the two fixed blocks, the rear ends of the outer walls of the two extrusion rollers are respectively movably connected to the corresponding arc grooves, and the front ends of the two extrusion rollers are movably connected to the second box cover.

[0013] By means of the above technical scheme, when in use, under the action of the fitting mechanism, a gap can be avoided between the dustproof belt and the partition plate, and then the tightening mechanism is used to tighten the dustproof belt to tighten the excess length of the dustproof belt, so as to prevent the dustproof belt from breaking when taking the dustproof belt and to make it more convenient when unloading. Specifically, the third motor on one side of one of the fixed blocks is started to drive the reverse threaded rod to rotate, and then the two movable blocks will move toward the center on the reverse threaded rod, and then under the support of the two movable rods, the two squeezing rollers will rotate along the corresponding arc grooves. At this time, since the two squeezing rollers are connected to the second box cover, the dustproof belt can be tightened along the rotation angle as the rear end rotates, so that the dustproof belt can completely form a closed dustproof space, so that the dustproof effect is maximized, and the dustproof belt can be quickly disassembled and installed when it needs to be unloaded. When the dustproof belt is replaced, the working process is the opposite of the above, and the whole process speeds up work efficiency and saves time.

[0014] The beneficial effects of the present invention are as follows: (1) The present invention can enable the electric energy meter box to accurately measure and count electric energy by designing a metering component, a dust removal mechanism, a fitting mechanism and a tightening mechanism, and can ensure that the internal mechanism is not disturbed by external dust after a long period of operation, and ensure that the internal metering elements can operate normally. In addition, after a long period of dust prevention, the dust prevention part can be regularly dusted and the dust removal components can be replaced; (2) The present invention can prevent external dust from entering the internal part and interfering with the metering elements through the dustproof belt during operation of the electric energy meter box by designing a dust removal mechanism and a fitting mechanism, and use the fitting mechanism to completely fit the dust removal belt to the inside of the electric energy meter box. The utility model is combined inside the box body to achieve complete isolation of dust. In the case of long-term isolation, the dust on the dustproof belt is removed by the dust removal mechanism, thereby avoiding long-term dust accumulation and reducing the isolation effect of the dustproof belt. At the same time, under the protection of the dustproof belt, it can effectively prevent dust and quickly dissipate heat, thereby greatly improving the performance of the electric energy meter box; (3) The present invention can isolate external dust on the dustproof belt during long-term use of the electric energy meter box by designing a tightening mechanism. The tightness of the dustproof belt can be controlled by the tightening mechanism to complete the replacement of the dustproof belt, thereby preventing dust from falling on the internal components and causing component short circuit, thereby significantly improving the safety of the electric energy meter box.
