Description

A three-phase wireless rail smart energy meter Technical Field

[0001] This utility model relates to the field of welding machine protection technology, and in particular to a three-phase wireless rail smart energy meter. Background Technology

[0002] A rectifier welding machine, also known as a rectifier welding transformer, is a special type of transformer that converts AC power from the grid into low-voltage AC power suitable for welding. It consists of a main transformer, the necessary regulating components, and indicating devices. In addition to the welding torch operated by the operator, a rectifier welding machine usually includes a main unit that provides power with specific characteristics.

[0003] Chinese patent CN218836550U discloses a rectifier welding machine. This device solves the technical problems of external interference such as exposure to sunlight and falling objects from heights by using a protective box, support column and protective baffle. These external interferences cause the welding machine to be inconvenient to move and lack protection during use. The protective box, support column and protective baffle can block external interference such as exposure to sunlight and falling objects from heights.

[0004] In the aforementioned utility models, the arc welding machine is mostly powered by an external wire inserted into the output end of the arc welding machine. Since the connection port is exposed outside the arc welding machine, it is easy for others to touch it, which may cause the connection port to loosen over time, posing a safety hazard. In addition, after the AC arc welding machine stops working, a lot of dust from the outside can easily enter the interior of the arc welding machine, making it difficult to block the dust. Summary of the Invention

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a three-phase wireless rail smart energy meter.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a three-phase wireless rail smart energy meter, comprising a smart meter, a buffer support, a sunshade cover, a display meter, a warning light, a wiring port, and a shielding device. The smart meter has a buffer support on its top, and a sunshade cover is installed on top of the buffer support. The display meter is installed at the front end of the smart meter, and a warning light is installed below the display meter. The wiring port is installed below the warning light, and the shielding device is installed at the front end of the wiring port. The shielding device includes a mounting box, a drive shaft, and a fixing mechanism. The mounting box comprises a mounting housing, a transmission push cylinder, a transmission rack, a transmission gear, a guide rail, and a shield assembly. The mounting housing is installed at the front end of the smartwatch. The transmission shaft is rotatably connected to the interior of the mounting housing. The transmission push cylinder is installed inside the mounting housing and is connected to the bottom of the transmission rack. The transmission push cylinder is also connected to the rear end of the transmission rack. The transmission rack is slidably connected to the top of the guide rail. The transmission rack meshes with the outer side of the transmission gear. The transmission gear is connected to the left end of the transmission shaft. The shield assembly is installed on the outer side of the transmission shaft.

[0007] Preferably, the masking assembly includes an installation roller, a drive rod, an installation block, a cleaning pad, and a masking plate. The installation roller is installed at the rear end of the drive shaft, the drive rod is slidably connected to the inside of the masking plate, the bottom of the drive rod is provided with an installation block, the cleaning pad is installed at the bottom of the installation block, and the masking plate is located at the left end of the installation roller.

[0008] In a further preferred embodiment, the transmission push cylinder and the transmission rack are arranged at the same horizontal level inside the mounting box.

[0009] In a further preferred embodiment, the guide rails are provided in two sets, and the two sets of guide rails are arranged at the same horizontal level at the bottom of the transmission rack.

[0010] In a further preferred embodiment, the mounting box and the fixing box are arranged parallel to each other at the front end of the smart watch.

[0011] In a further preferred embodiment, the teeth on the outer side of the transmission rack mesh with the teeth on the outer side of the transmission gear, which facilitates meshing and transmission between the outer sides of the transmission rack and the transmission gear, thereby reducing power loss.

[0012] In a further preferred embodiment, the interior of the shielding plate is provided with a rectangular groove.

[0013] In a further preferred embodiment, the transmission rod and the mounting block are vertically arranged on the cover plate, which facilitates the transmission rod to move the mounting block to slide horizontally along the cover plate.

[0014] The beneficial effects of this utility model are:

[0015] This invention incorporates a shielding device. A transmission cylinder pushes a transmission rack to move horizontally, causing the rack to mesh with a transmission gear. This allows the transmission gear to rotate the transmission shaft via a nested transmission mechanism. The transmission shaft then rotates the mounting roller. Furthermore, the shielding assembly is positioned outside the transmission shaft, providing protection. This shielding device, placed at the wiring port, isolates the port from dust, preventing prolonged exposure and dust accumulation. This addresses the problem in the original equipment where, after the arc welding machine stopped working, external dust easily entered the machine, making dust containment difficult.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please refer to Figures 1-2. This utility model provides a three-phase wireless rail smart energy meter, including a smart meter 1, a buffer support 2, a sunshade cover 3, a display meter 4, a warning light 5, a wiring port 6, and a shielding device 7. The buffer support 2 is provided on the top of the smart meter 1, and the sunshade cover 3 is installed on the top of the buffer support 2. The display meter 4 is installed at the front end of the smart meter 1, and the warning light 5 is installed below the display meter 4. The wiring port 6 is installed below the warning light 5, and the shielding device 7 is installed at the front end of the wiring port 6.

[0024] Please refer to Figures 3-4. This utility model provides a three-phase wireless rail smart energy meter. The shielding device 7 includes a mounting box 71, a drive shaft 72, a fixing box 73, a drive cylinder 74, a drive rack 75, a drive gear 76, a guide rail 77, and a shielding assembly 78. The mounting box 71 is installed at the front end of the smart meter 1. The drive shaft 72 is rotatably connected to the inside of the mounting box 71. The drive cylinder 74 is installed inside the mounting box 71 and is driven to the bottom of the drive rack 75. The drive cylinder 74 is also driven to the rear end of the drive rack 75. The drive rack 75 is slidably connected to the top of the guide rail 77. The drive rack 75 meshes with the outer side of the drive gear 76. The drive gear 76 is driven to the left end of the drive shaft 72. The shielding assembly 78 is installed on the outer side of the drive shaft 72.

[0025] In this embodiment, the transmission push cylinder 74 and the transmission rack 75 are arranged at the same level inside the mounting box 71. Two sets of guide slide rails 77 are arranged at the same level at the bottom of the transmission rack 75. The mounting box 71 and the fixing box 73 are arranged parallel to each other at the front end of the smart meter 1. The teeth on the outer side of the transmission rack 75 mesh with the teeth on the outer side of the transmission gear 76, which is conducive to the meshing and transmission of the outer side of the transmission rack 75 and the transmission gear 76, thereby reducing the loss of power.

[0026] Please refer to Figure 5. This utility model provides a three-phase wireless rail smart energy meter. The shielding assembly 78 includes an installation roller 781, a transmission rod 782, an installation block 783, a cleaning pad 784, and a shielding plate 785. The installation roller 781 is installed at the rear end of the transmission shaft 72. The transmission rod 782 is slidably connected to the inside of the shielding plate 785. The installation block 783 is provided at the bottom of the transmission rod 782. The cleaning pad 784 is installed at the bottom of the installation block 783. The shielding plate 785 is provided at the left end of the installation roller 781.

[0027] In this embodiment, the interior of the cover plate 785 is provided with a rectangular groove, and the transmission rod 782 and the mounting block 783 are vertically arranged on the cover plate 785, so that the transmission rod 782 can move the mounting block 783 to slide horizontally along the cover plate 785.

[0028] Referring to Figures 1-5, when using the smart meter 1 outdoors, the sunshade 3 is placed on the outside of the smart meter 1 to prevent smoke and light from shining on the smart meter 1 and affecting its normal operation. The power supply equipment is connected through the wiring port 6 so that it can monitor the power supply equipment in real time. When the power equipment malfunctions, the warning light 5 can change to produce a warning.

[0029] When the equipment is not needed, the transmission rack 75 can be moved horizontally by the transmission push cylinder 74, so that the transmission rack 75 and the transmission gear 76 can mesh and drive, so that the transmission gear 76 can drive the transmission shaft 72 to rotate through the nested transmission, and the transmission shaft 72 drives the installation roller 781 to rotate.

[0030] Furthermore, the installation roller 781 rotates the cover plate 785, allowing it to cover the front end of the wiring port 6, preventing the wiring port 6 from directly contacting dust and causing dust to adhere to the top of the wiring port 6. Subsequently, the transmission rod 782 is manually moved, pulling the installation block 783 to move up and down. This allows the cleaning pad 784 located below the installation block 783 to wipe away the dust adsorbed inside the wiring port 6. Then, the cover assembly 78 is set on the outside of the transmission shaft 72, providing a protective cover. This achieves the goal of isolating the wiring port 6 from dust, preventing it from being exposed to the outside for a long time and easily accumulating dust. This solves the problem in the original equipment where, after the arc welding machine stopped working, a lot of external dust could easily enter the arc welding machine, making it difficult to block the dust.

[0031] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0032] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
