Description

Technical Field

[0001] The utility model relates to the field of high-voltage live working equipment, in particular to a high-voltage live indicating device. Background Art

[0002] High-voltage live display equipment is extremely important equipment in high-voltage operations. For operators, the reliability of high-voltage live equipment is crucial. The live display equipment widely used in the current power system is relatively mature and can well monitor the live status of equipment or power cables.

[0003] According to a Chinese patent with the announcement number CN220040589U, a high-voltage live display device is disclosed. This utility model provides redundant spare indicator lights and switches them through switches of corresponding phases. In the event that only the indicator lights of the high-voltage live display device are damaged, there is no need to replace the high-voltage live display device, thereby reducing costs and eliminating the danger of replacing the high-voltage live display device.

[0004] Regarding the above-mentioned disclosed patent content, three switches are provided so that the switches correspond to the indicator lights. However, the switches may be accidentally touched when the device is used. Since it is difficult to lock the switches to a limit position, the standby indicator lights up when the switch is accidentally touched without needing to be lit. As a result, the staff may misjudge that the A-phase indicator light, the B-phase indicator light or the C-phase indicator light is damaged, thereby affecting the indication effect of the indicating device. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a high-voltage live indicator device to solve the technical problem that the switch is easily touched by mistake, thereby causing the standby indicator light to light up at will.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-voltage live indicating device, comprising a shell, a panel mounted on the outer surface of the shell, and an A-phase switch, a B-phase switch and a C-phase switch and three locking assemblies respectively provided below the outer surface of the panel, the locking assemblies comprising three rotating shafts provided on the outer surface of the panel, three limiting grooves provided below the outer surface of the panel and locking holes provided on one side of the top of the A-phase switch, the B-phase switch and the C-phase switch, a pressure plate being sleeved on the outer wall of the rotating shaft, a limiting block being provided inside the limiting groove, a lifting block being mounted on the outer surface of the limiting block, and a locking column extending to the inside of the locking hole being provided at the bottom of the lifting block, and a pull plate being connected between the lifting block and the pressure plate via a movable shaft.

[0007] By adopting the above technical solution, when the locking column is moved out of the locking hole, the A-phase switch, the B-phase switch and the C-phase switch are no longer locked, and the A-phase switch, the B-phase switch and the C-phase switch can be pressed.

[0008] Furthermore, two groups of A-phase indicator lights, B-phase indicator lights and C-phase indicator lights are respectively installed on the outer surface of the panel.

[0009] By adopting the above technical solution, when detecting the A-phase high-voltage bus, the indicator light is the A-phase indicator light; when used to detect the B-phase high-voltage bus, the indicator light is the B-phase indicator light; when detecting the C-phase high-voltage bus, the indicator light is the C-phase indicator light.

[0010] Furthermore, a plurality of dust covers are installed on the outer surface of the panel, and the plurality of dust covers correspond one to one with the A phase indicator light, the B phase indicator light and the C phase indicator light respectively.

[0011] By adopting the above technical solution, the dust cover can shield the A phase indicator light, the B phase indicator light and the C phase indicator light, thereby reducing the amount of dust accumulated on the surfaces of the A phase indicator light, the B phase indicator light and the C phase indicator light.

[0012] Furthermore, the pressure plate is rotatably connected to the panel via a rotating shaft.

[0013] By adopting the above technical solution, the pressing plate can be rotated through the rotating shaft, and the pulling plate will be pulled when the pressing plate rotates.

[0014] Furthermore, one side of the pressing plate is arc-shaped, and a rubber sleeve is provided on the outer wall of the pressing plate.

[0015] By adopting the above technical solution, it is convenient for the staff to press the pressing plate, thereby enabling the pressing plate to rotate.

[0016] Furthermore, the lifting block is slidably connected to the limiting groove via a limiting block.

[0017] By adopting the above technical solution, when the lifting block moves, it will drive the limiting block to slide inside the limiting groove, thereby improving the stability of the lifting block when moving.

[0018] Furthermore, the locking column is adapted to the locking hole.

[0019] By adopting the above technical solution, after the locking column is moved into the locking hole, the A-phase switch, B-phase switch and C-phase switch can be locked to prevent the A-phase switch, B-phase switch and C-phase switch from being accidentally touched.

[0020] Furthermore, the pull plate is rotatably connected to the pressure plate via a movable shaft, and the length of the pull plate is greater than the length of the locking column.

[0021] By adopting the above technical solution, when the pressure plate rotates, it will pull the pull plate upward, and make the pull plate rotate through the movable shaft, and then drive the locking column to move.

[0022] Furthermore, an insulating sleeve is sleeved on the outer wall of the panel.

[0023] By adopting the above technical solution, the provision of the insulating sleeve can play an insulating role and protect the outer wall of the panel at the same time.

[0024] Furthermore, a spring is installed above the interior of the limiting groove, and the bottom end of the spring is connected to the top of the limiting block.

[0025] By adopting the above technical solution, when the limit block moves upward, it will squeeze the spring, causing the spring to be compressed, making it easier to push the limit block to reset and move.

[0026] In summary, the present invention has the following beneficial effects:

[0027] The utility model is provided with a locking assembly. When there is no need to press the A phase switch, B phase switch or C phase switch, the pressure plate is released. At this time, the spring is stretched and the limit block is pushed to reset and move. The limit block drives the lifting block to move and drives the locking column to move so that the locking column moves into the locking hole, thereby locking the A phase switch, B phase switch or C phase switch to a limit position, preventing the A phase switch, B phase switch or C phase switch from being accidentally touched, thereby improving the use effect of the device and avoiding the indicator light from lighting up at random, preventing the staff from making misjudgments. When the A phase switch, B phase switch or C phase switch needs to be pressed, the pressure plate can be pressed to rotate the pressure plate and pull the pulling plate to move. The pulling plate pulls the locking column to move and drives the limit block to slide inside the limit groove. The limit block compresses the spring. After the locking column moves out of the locking hole, the A phase switch, B phase switch and C phase switch are no longer locked. At this time, the A phase switch, B phase switch or C phase switch can be pressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] Example 1:

[0037] A high voltage live indication device, such as Figure 1-Figure 5 As shown, it includes a shell 1, a panel 2 is installed on the outer surface of the shell 1, and an A-phase switch 6, a B-phase switch 7 and a C-phase switch 8 and three locking assemblies 9 are respectively provided below the outer surface of the panel 2, and two groups of A-phase indicator lights 3, B-phase indicator lights 4 and C-phase indicator lights 5 are respectively installed above the outer surface of the panel 2, wherein one group of A-phase indicator lights 3, B-phase indicator lights 4 and C-phase indicator lights 5 are standby indicator lights, and the A-phase switch 6 is electrically connected to the A-phase switch 6, the B-phase switch 7 is electrically connected to the B-phase indicator light 4, and the C-phase switch 8 is electrically connected to the C-phase indicator light 5. When detecting the A-phase high-voltage busbar, the indicator light is the A-phase indicator light 3; when used to detect the B-phase high-voltage busbar, the indicator light is the B-phase indicator light 4; when detecting the C-phase high-voltage busbar, the indicator light is the C-phase indicator light 5.

[0038] Specifically, the locking assembly 9 includes three rotating shafts 901 provided on the outer surface of the panel 2, three limiting grooves 908 opened below the outer surface of the panel 2, and locking holes 906 opened on one side of the top of the A-phase switch 6, the B-phase switch 7 and the C-phase switch 8. The outer wall of the rotating shaft 901 is sleeved with a pressure plate 902, and the pressure plate 902 is rotatably connected to the panel 2 through the rotating shaft 901. The pressure plate 902 can be rotated through the rotating shaft 901. When the pressure plate 902 rotates, it will pull the pulling plate 903. One side of the pressure plate 902 is arc-shaped, and the outer wall of the pressure plate 902 is provided with a rubber sleeve to facilitate the staff to press the pressure plate 902, thereby enabling the pressure plate 902 to rotate.

[0039] Specifically, a limiting block 909 is set inside the limiting groove 908, and a lifting block 907 is installed on the outer surface of the limiting block 909, and a locking column 905 extending to the inside of the locking hole 906 is provided at the bottom of the lifting block 907, and a pulling plate 903 is connected between the lifting block 907 and the pressure plate 902 through a movable shaft 904. When the locking column 905 is moved out of the locking hole 906, the A-phase switch 6, the B-phase switch 7 and the C-phase switch 8 are no longer locked, and the A-phase switch 6, the B-phase switch 7 and the C-phase switch 8 can be pressed. The lifting block 907 is slidably connected to the limiting groove 908 through the limiting block 909. When the lifting block 907 moves, it will drive the limiting block 909 to slide inside the limiting groove 908, thereby improving the stability of the lifting block 907 during movement.

[0040] Specifically, the locking column 905 is adapted to the locking hole 906. After the locking column 905 moves into the locking hole 906, the A phase switch 6, the B phase switch 7 and the C phase switch 8 can be locked to prevent the A phase switch 6, the B phase switch 7 and the C phase switch 8 from being accidentally touched. The pull plate 903 is rotatably connected to the pressure plate 902 through the movable shaft 904. The length of the pull plate 903 is greater than the length of the locking column 905. When the pressure plate 902 rotates, it will pull the pull plate 903 upward and make the pull plate 903 rotate through the movable shaft 904, and then drive the locking column 905 to move. A spring 910 is installed on the upper part of the limit groove 908, and the bottom end of the spring 910 is connected to the top of the limit block 909. When the limit block 909 moves upward, it will squeeze the spring 910, so that the spring 910 is compressed, which is convenient for pushing the limit block 909 to reset and move.

[0041] Example 2:

[0042] On the basis of the above-mentioned embodiment 1, in order to prevent a large amount of dust from adhering to the indicator light and affecting the brightness and color of the indicator light observed by the staff, the following structure is provided to reduce dust accumulation.

[0043] See Figure 1-Figure 3 A plurality of dust covers 10 are also installed on the outer surface of the panel 2, and the plurality of dust covers 10 correspond to the A phase indicator light 3, the B phase indicator light 4 and the C phase indicator light 5 respectively. The dust covers 10 can block the A phase indicator light 3, the B phase indicator light 4 and the C phase indicator light 5, thereby reducing the amount of dust accumulated on the surface of the A phase indicator light 3, the B phase indicator light 4 and the C phase indicator light 5.

[0044] Example 3:

[0045] On the basis of the above-mentioned embodiment 1, in order to protect the outer wall of the panel 2 and prevent the outer wall of the panel 2 from colliding with external objects and causing wear, the following structure is provided.

[0046] See Figure 1-Figure 3The outer wall of the panel 2 is sleeved with an insulating sleeve 11. The setting of the insulating sleeve 11 can play an insulating role and protect the outer wall of the panel 2 at the same time.

[0047] The working principle of the utility model is as follows: first, in actual application, when the high-voltage busbar is obviously energized, the A-phase indicator light 3, the B-phase indicator light 4 and the C-phase indicator light 5 are all on. If the staff finds that the indicator light of a certain phase is not on, they can press the switch of the corresponding phase. If the standby indicator light is on, it proves that the indicator light of the phase is damaged, and the standby indicator light can continue to be used without disassembling and replacing the high-voltage live display device; if the standby indicator light is off, it proves that the high-voltage busbar has no electricity or the high-voltage live display device is faulty, and further inspection is required;

[0048] When the A-phase switch 6, the B-phase switch 7 or the C-phase switch 8 does not need to be pressed during use, the locking column 905 will be locked into the locking hole 906, thereby locking the A-phase switch 6, the B-phase switch 7 or the C-phase switch 8 to prevent the A-phase switch 6, the B-phase switch 7 or the C-phase switch 8 from being accidentally touched. When the A-phase switch 6, the B-phase switch 7 or the C-phase switch 8 needs to be pressed, the pressure plate 902 can be pressed to rotate and pull the pull plate 903 to move. The pull plate 903 pulls the locking column 905 to move and drives the limit block 909 to slide inside the limit groove 908. The limit block 909 squeezes the spring 910. After the locking column 905 is removed from the locking hole 906, the A-phase switch 6, the B-phase switch 7 and the C-phase switch 8 are no longer locked. At this time, the A-phase switch 6, the B-phase switch 7 or the C-phase switch 8 can be pressed.

[0049] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
