[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0032] like Figure 1-8 As shown: a new type of isolation and grounding mechanism opening and closing indication device, including a mounting base plate 1, a mounting hole is arranged on the mounting base plate 1, and the mounting base plate 1 is fixedly connected to the isolation and grounding mechanism by screws, an opening and closing indication cover 3 is installed on the mounting base plate 1, and a disassembly and assembly component for fixing and disassembling the opening and closing indication cover 3 is arranged between the opening and closing indication cover 3 and the mounting base plate 1.
[0033] The disassembly and assembly components include a positioning buckle 2, a buckle edge 4 and an embedded block 11. The positioning buckle 2 is fixedly set on the mounting base plate 1, the buckle edge 4 is fixedly set at the lower end of the opening and closing indicator cover 3, and the embedded block 11 is fixedly set on the buckle edge 4. The position distribution of the embedded block 11 corresponds one-to-one with the positioning buckle 2, which facilitates the alignment and connection of the embedded block 11 on the buckle edge 4 with the positioning buckle 2.
[0034] The positioning buckle 2 and the mounting base plate 1 form an integrated structure, and the buckle edge 4, the embedded block 11 and the opening and closing indicator cover 3 also form an integrated structure. A groove with the same size as the embedded block 11 is provided inside the positioning buckle 2. The embedded block 11 on the buckle edge 4 can be connected with the positioning buckle 2 to ensure the stability of the opening and closing indicator cover 3 in the mounting base plate 1, and it is also convenient to disassemble and assemble the opening and closing indicator cover 3.
[0035] An opening and closing indication core 8 is connected inside the opening and closing indication cover 3, and the opening and closing indication core 8 is connected to the motor drive movement of the isolation grounding mechanism. A cleaning component for cleaning the surface of the opening and closing indication cover 3 is arranged between the upper end of the opening and closing indication core 8 and the opening and closing indication cover 3.
[0036] The cleaning component includes a connecting rod 5 and a brush 6, the brush 6 is fixed on the periphery of the connecting rod 5, and four brushes 6 are symmetrically arranged on the outer center of the opening and closing indicator cover 3. Brush bristles 14 are fixed on the inner side of the brush 6, and the bristles 14 are in contact and connected with the outer surface of the opening and closing indicator cover 3. The outer surface of the opening and closing indicator cover 3 can be cleaned frequently by the brush 6, effectively avoiding the outer surface of the opening and closing indicator cover 3 from being blocked by dust, thereby ensuring the normal light transmission effect of the opening and closing indicator cover 3.
[0037] The connecting rod 5 passes through the center position of the outer end of the opening and closing indicator cover 3. An extrusion sheet 13 is fixedly provided at one end of the connecting rod 5 located inside the opening and closing indicator cover 3. A spring 7 is provided between the extrusion sheet 13 and the opening and closing indicator cover 3. The spring 7 is sleeved on the connecting rod 5 to ensure that the connecting rod 5 can move in the upper and lower positions on the opening and closing indicator cover 3, and the free movement of the connecting rod 5 is also limited by the spring 7.
[0038] A connecting block 10 is fixedly provided at one end of the connecting rod 5 located inside the opening and closing indicator cover 3. The connecting block 10 is in the shape of a regular quadrangular prism and is inserted into the end of the opening and closing indicator core 8. The opening and closing indicator core 8 can drive the connecting rod 5 to rotate through the connecting block 10, thereby enabling the brush 6 to clean the surface of the opening and closing indicator cover 3.
[0039] A light strip 9 is installed on the opening and closing indicator core 8, and the opening and closing indicator cover 3 is made of transparent plastic material to ensure normal light transmission, wherein the power supply of the light strip 9 comes from the 220V AC in the isolation grounding mechanism box.
[0040] A limit block 12 is fixedly arranged inside the opening and closing indicator cover 3, and four limit blocks 12 are symmetrically arranged inside the opening and closing indicator cover 3. The combined size between the limit blocks 12 is equal to the outer size of the opening and closing indicator core 8, which can ensure the stability of the working state between the opening and closing indicator cover 3 and the opening and closing indicator core 8.
[0041] The size of the light strip 9 on the opening and closing indicator core 8 is smaller than the spacing between adjacent limit blocks 12. The opening and closing indicator core 8 between adjacent limit blocks 12 is divided into red and green transparent plastics, and the two colors of transparent plastics are arranged at intervals, which can ensure that the light emitted by the light strip 9 is isolated by the limit blocks 12, so that the opening and closing indicator cover 3 can emit pure red or green light, avoiding the mixing of light and causing unclear luminous color.
[0042] First, install the mounting base plate 1 in the working position, fix the opening and closing indication core 8 with the motor movement, then cover the opening and closing indication cover 3 on the opening and closing indication core 8, and at the same time ensure that the connecting block 10 in the opening and closing indication cover 3 is inserted and connected to the opening and closing indication core 8, then press the opening and closing indication cover 3 to rotate, so that the embedding block 11 on the buckle edge 4 rotates to the upper and lower relative position of the positioning buckle 2, and then release the pressure on the opening and closing indication cover 3, under the action of the spring 7 on the connecting rod 5, the opening and closing indication cover 3 is pushed outward, and the embedding block 11 will be embedded in the positioning buckle 2, and the state of the opening and closing indication cover 3 will be fixed;
[0043] When the isolation grounding mechanism is performing the opening and closing operation, the motor drives the gear to rotate, and the movement will drive the opening and closing indicating core 8 to rotate together. When the closing is in place, the light strip 9 on the opening and closing indicating core 8 lights up, and the reflected light after passing through the opening and closing indicating cover 3 shows red. When the opening is in place, the opening and closing indicating core 8 reflects the light after being illuminated by the light strip 9 and shows green, so that the specific situation of the opening and closing can be displayed in real time;
[0044] When the switch-on / off indicating core 8 rotates, the connecting rod 5 is driven to rotate through the connecting block 10, thereby causing the brush piece 6 to rotate outside the switch-on / off indicating cover 3, and the bristles 14 on the brush piece 6 can clean the dust on the outer surface of the switch-on / off indicating cover 3, effectively avoiding dust accumulation and ensuring the normal lighting effect of the switch-on / off indicating cover 3;
[0045] If the opening and closing indicator cover 3 needs to be disassembled later, the opening and closing indicator cover 3 can be pressed to disengage the embedded block 11 on the buckle edge 4 from the positioning buckle 2 on the mounting base 1, and the opening and closing indicator cover 3 can be directly removed by continuing to rotate the opening and closing indicator cover 3.
