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.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an outdoor high-voltage disconnect switch box, comprising a box body 1, a top plate 2 is fixedly installed on the top of the box body 1, an opening and closing door 3 is rotatably connected to one side of the box body 1, a mounting mechanism 4 that can be pulled out of the box body 1 is fixedly installed on the bottom of the inner wall of the box body 1, and the disconnector is fixedly installed on the mounting mechanism 4, a supporting mechanism 6 for supporting the mounting mechanism 4 is fixedly installed on the bottom of the mounting mechanism 4, and a positioning mechanism 5 for positioning and locking the mounting mechanism 4 is fixedly installed on one side of the inner wall of the box body 1.

[0019] Among them, by setting up the installation mechanism 4, the high-voltage disconnector to be installed can be installed and supported, and the installation mechanism 4 can be pulled out of the box body 1, so as to facilitate the construction personnel to install the heavy high-voltage disconnector. When the installation mechanism 4 is pulled out of the box body 1, the support mechanism 6 is rotated, so that the support mechanism 6 can be used to support and limit one side of the installation mechanism 4, so as to prevent the installation mechanism 4 from tipping over due to the heavy weight of the disconnector, and the positioning mechanism 5 can be positioned when the installation mechanism 4 is pulled out and pushed in, to prevent the installation mechanism 4 from displacement and shaking when the high-voltage disconnector is installed.

[0020] See also Figure 1The mounting mechanism 4 includes a slide rail 7, a slider 8, a connecting block 9, a mounting plate 10 and a fixing groove 11. Two groups of slide rails 7 are fixedly installed at the bottom of the inner wall of the box body 1. Two groups of sliders 8 are slidably connected to the slide rails 7. The top of the slider 8 is fixedly installed with a mounting plate 10 through a connecting block 9. Multiple groups of fixing grooves 11 are penetrated through the mounting plate 10. A guide groove 12 set in the X direction is opened on the top of the mounting plate 10. A fixing hole 13 set in the Z axis direction is opened on the mounting plate 10 and corresponds to the guide groove 12. A handle 29 is fixedly connected to one side of the mounting plate 10.

[0021] When the high-voltage disconnector needs to be installed, the positioning mechanism 5 is separated from the mounting mechanism 4, and then the handle 29 is pulled. The handle 29 drives the mounting plate 10 and the slider 9 to move along the slide rail 7, so that the mounting plate 10 used for installing the high-voltage disconnector can be separated from the interior of the box 1, and then the high-voltage disconnector can be fixedly installed using the fixing groove 11.

[0022] See also Figure 1 and Figure 2 The positioning mechanism 5 includes a fixing plate 14, a positioning rod 15, a pull rod 16 and a spring 17. The fixing plate 14 is fixedly installed on one side of the inner wall of the box body 1. The fixing plate 14 is slidably connected with the positioning rod 15 at the position corresponding to the fixing hole 13. The pull rod 16 is fixedly installed on the top of the positioning rod 15. The top of the fixing plate 14 and the outer surface of the positioning rod 15 are fixedly connected with a spring 17. The top of the spring 17 is fixedly installed on the bottom of the pull rod 16. The inner wall of the box body 1 and the bottom of the fixing plate 14 are fixedly connected by a reinforcing plate 28 made of rigid material.

[0023] When it is necessary to detach the mounting plate 10 from the interior of the box body 1, pull the pull rod 16 to detach the positioning rod 15 from the interior of the fixing hole 13, and then pull the mounting plate 10 and the handle 29. Then, due to the action of the spring 17, the bottom of the positioning rod 15 can contact the guide groove 12. Then, as the mounting plate 10 is continuously pulled out, the setting of the spring 17 can push the positioning rod 15 to be reinserted into another set of fixing holes 13, thereby completing the locking and fixation of the mounting plate 10.

[0024] See also Figure 1 and Figure 3The support mechanism 6 includes a support sleeve 18 and a telescopic rod 19. A hidden groove 30 is provided at the bottom of the inner wall of the box body 1 and corresponds to the position of the support mechanism 6 so that it is hidden inside the box body 1. The support sleeve 18 is fixedly installed at the bottom of the mounting plate 10. The telescopic rod 19 is slidably connected inside the support sleeve 18. A moving groove 20 is penetrated through the support sleeve 18. A first locking groove 21 and a second locking groove 22 that are connected to the moving groove 20 are penetrated through the surface of the support sleeve 18. A locking column 23 is fixedly installed on the surface of the telescopic rod 19 and corresponds to the position of the first locking groove 21.

[0025] Among them, when the mounting plate 10 is completely pulled out of the box body 1, the supporting mechanism 6 can be taken out from the inside of the hidden groove 30. At this time, the locking column 23 is clamped in the inside of the second locking groove 22, and then the telescopic rod 19 is rotated to move the locking column 23 to the position of the movable groove 20. When the locking column 23 moves to the position of the first locking groove 21, the telescopic rod 19 is rotated in the opposite direction again, so that the locking column 23 can be inserted into the inside of the first locking groove 21, so that the bottom of the telescopic rod 19 can contact the ground, completing the support and limiting of the mounting plate 10.

[0026] See also Figure 1 A plurality of ventilation grooves 24 are provided on both sides of the box body 1 , and a plurality of baffles 25 are fixedly installed on both sides of the outer wall of the box body 1 and corresponding to the positions of the ventilation grooves 24 .

[0027] The ventilation grooves 24 are provided to facilitate timely dissipation of heat inside the box body 1 , and the baffles 25 are provided to block the ventilation grooves 24 , thereby preventing impurities from entering the inside of the box body 1 through the ventilation grooves 24 .

[0028] See also Figure 1 An observation window 26 is provided on the surface of the opening and closing door 3, and a sealing strip 27 made of rubber material is fixedly installed on the surface of the opening and closing door 3. The setting of the observation window 26 can timely observe the situation inside the box body 1, and the setting of the sealing strip 27 can play a sealing effect when the opening and closing door 3 is closed.

[0029] When in use, first, when the high-voltage disconnector needs to be installed, the positioning mechanism 5 is separated from the installation mechanism 4, and then the handle 29 is pulled, and the handle 29 drives the mounting plate 10 and the slider 9 to move along the slide rail 7, so that the mounting plate 10 used for the installation of the high-voltage disconnector can be separated from the inside of the box body 1, and then the high-voltage disconnector can be fixedly installed using the fixing groove 11. When the mounting plate 10 needs to be separated from the inside of the box body 1, the pull rod 16 is pulled to separate the positioning rod 15 from the inside of the fixing hole 13, and then the mounting plate 10 and the handle 29 are pulled. Then, due to the action of the spring 17, the bottom of the positioning rod 15 can contact the guide groove 12, and then the mounting plate 1 0 is continuously pulled out, the setting of the spring 17 can push the positioning rod 15 to be reinserted into another set of fixing holes 13, thereby completing the locking and fixing of the mounting plate 10. When the mounting plate 10 is completely pulled out of the box body 1, the supporting mechanism 6 can be taken out from the inside of the hidden groove 30. At this time, the locking column 23 is engaged with the inside of the second locking groove 22, and then the telescopic rod 19 is rotated to move the locking column 23 to the position of the moving groove 20. When the locking column 23 moves to the position of the first locking groove 21, the telescopic rod 19 is rotated in the opposite direction again, so that the locking column 23 can be inserted into the inside of the first locking groove 21, so that the bottom of the telescopic rod 19 can be in contact with the ground, completing the support and limiting of the mounting plate 10.
