[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 6 As shown, the utility model provides a dual-power dual-point padlock device, including a sliding cover and handle assembly 1, a surface cover 2, a padlock cover 3, a manual cover plate 4, a padlock 5, and a fixing member 6. The sliding cover and handle assembly 1 is installed on the top of the surface cover 2, and the sliding cover and handle assembly 1 is slidably connected to the surface cover 2. When the sliding cover and handle assembly 1 slide to the leftmost side, the primary manual operation window 7 is completely exposed. A primary manual operation window 7 is provided at a position corresponding to the sliding cover and handle assembly 1 on the surface cover 2. The bottom of the surface cover 2 is slidably connected to the manual cover plate 4. Two secondary manual operation windows 8 are provided at positions corresponding to the primary manual operation window 7 on the manual cover plate 4. The operator's hand can pass through the primary manual operation window 7 and the secondary manual operation window 8 to perform dual power operation. A padlock limiting hole 9 is provided on the right side of the secondary manual operation window 8. After the limiting plate 11 enters the limiting groove 12, the padlock hole 10 is located above the manual cover plate 4, and the padlock can be locked. The padlock 5 is provided at The padlock 5 is in the padlock limiting hole 9, and the padlock 5 can move up and down in the padlock limiting hole 9. The padlock 5 is provided with a padlock hole 10, and the padlock hole 10 is blocked by the hand cover plate 4 under normal circumstances. The padlock cover 3 is installed on the top of the padlock 5, and the padlock cover 3 is above the padlock limiting hole 9. The bottom of the padlock 5 is fixedly connected to the limiting plate 11, and the limiting plate 11 is under the fixing member 6 under normal circumstances and can move left and right. The fixing member 6 is arranged under the cover 2, and the fixing member 6 and the padlock 5 are slidably arranged. The fixing member 6 structure matches the padlock 5. When not padlocked, the padlock 5 can slide relative to the fixing member 6. The fixing member 6 is provided with a limiting groove 12 corresponding to the limiting plate 11. The limiting plate 11 moves left to the bottom of the limiting groove 12, and can enter the limiting groove 12 after moving up to limit the movement of the limiting plate 11. At this time, the padlock hole 10 on the padlock 5 is exposed and can be padlocked.
[0025] Specifically, a slide rail 13 of a sliding cover and handle assembly is provided on the top of the face cover 2 , and a positioning column 14 is slidably connected to the slide rail 13 of the sliding cover and handle assembly, and the positioning column 14 is fixed to the bottom of the sliding cover and handle assembly 1 .
[0026] Furthermore, slide plates 15 are provided at the front and rear sides of the manual operation cover plate 4 , and the slide plates 15 are slidably connected to manual operation cover plate slide rails 16 , which are provided at the bottom of the face cover 2 .
[0027] Furthermore, the size of the padlock cover 3 is larger than the size of the padlock limiting hole 9 .
[0028] It is worth noting that a mounting groove 17 is provided at the bottom of the padlock cover 3 , and the top end of the padlock 5 is mounted in the mounting groove 17 .
[0029] It is worth noting that the sliding cover and handle assembly 1 can slide left and right on the face cover 2, and the hand-operated cover plate 4 can slide left and right at the bottom of the face cover 2.
[0030] It is worth mentioning that the limit plate 11 is located below the fixing member 6, and the structure of the limit plate 11 corresponds to the limit groove 12. The limit plate 11 moves left and right below the fixing member 6. After moving up to the limit groove 12, the padlock hole 10 of the padlock member 5 leaks out and can be padlocked. The limit plate 11 is restricted in the limit groove 12, so that the padlock member 5 is locked in this position.
[0031] Working principle and process: When performing inspection or maintenance operations, the power supply and the load end are in a disconnected electrical isolation state (i.e., a double-split state). At this time, the sliding cover and the handle assembly 1 slide to the left, so that the primary manual operation window 7 leaks out, the manual operation cover plate 4 is pushed to move left, and the padlock 5 moves left with the manual operation cover plate 4. The limit plate 11 fixedly connected to the bottom of the padlock 5 moves under the fixing part 6 until the limit plate 11 is directly under the limit groove 12. At the same time, the secondary manual operation window 8 moves to the lower left of the primary manual operation window 7, and the secondary manual operation window 8 is completely hidden, so that personnel can enter the manual operation window 7. The hand cannot pass through the primary manual operation window 7 and the secondary manual operation window 8 to perform dual power supply operation, pull the padlock cover 3 upwards, the padlock 5 and the limit plate 11 move upwards, and the padlock hole 10 leaks out, so as to lock the padlock 5 and prevent it from moving downward. At the same time, the limit plate 11 is in the limit groove 12 of the fixing member 6, so that the padlock 5 cannot move left and right, that is, the position of the manual cover plate 4 is fixed, so as to prevent others from operating the switch by mistake, ensure that the power supply and the load end are in a disconnected electrical isolation state (i.e., a dual-split state), and ensure the electrical safety of the inspection and maintenance personnel.
