DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figure 1-Figure 5 The utility model provides a low-voltage switch cabinet isolation protection mechanism, including an auxiliary rain shield component 10 and a limit component 20.

[0026] Among them, the auxiliary rain shield component 10 is installed on the top of the distribution cabinet in conjunction with the limit component 20. It can increase the rain shielding area when performing maintenance work in advance, reduce the entry of rainwater into the distribution cabinet during maintenance, and have a good protective effect on the distribution cabinet.

[0027] The auxiliary rain shield assembly 10 includes a V-shaped top cover plate 110, a position limiting portion 120, and a handle 130. The position limiting portion 120 is arranged on the upper side of the top cover plate 110, and the handle 130 is installed at the front end of the top cover plate 110.

[0028] See also Figure 1 and Figure 5 The limiting assembly 20 includes a limiting strip 210 and a fixing block 220. The fixing block 220 is integrally formed and fixed to the rear end of the limiting strip 210. The fixing block 220 is fixed to the top of the power distribution cabinet via fixing bolts 240. The top cover 110 is slidably disposed between the top of the power distribution cabinet and the limiting strip 210. The limiting strip 210 is provided with a groove 230, and the limiting portion 120 is slidably engaged with the groove 230.

[0029] When performing maintenance on rainy days, the maintenance personnel grasp the handle 130 at the front end of the top cover plate 110 and pull the handle 130 to move the top cover plate 110 forward between the top of the distribution cabinet and the limiting strip 210. This causes the top cover plate 110, which is originally located above the top of the distribution cabinet, to move to the front side above the distribution cabinet. This effectively reduces the possibility of rainwater from outside entering the distribution cabinet while the operator is performing maintenance work, thus providing good protection for the distribution cabinet. After the maintenance work on the distribution cabinet is completed, the maintenance personnel grasp the handle 130 and push the top cover plate 110 to the top of the top cover plate 110 to complete the reset. This reduces the space occupied by the protective mechanism and prevents the top cover plate 110 from protruding and coming into contact with other objects.

[0030] For specific settings, please refer to Figure 4 and Figure 5 The limiting portion 120 includes a limiting pin 121, the bottom end of which is fixedly connected to the inclined surface of the top cover plate 110, and a slot 230 is slidably sleeved on the outside of the limiting pin 121. The limiting portion 120 also includes a limiting block 122, which is located above the limiting strip 210 and fixed to the top of the limiting pin 121. The sliding fit between the limiting portion 120 and the slot 230 improves the stability of the top cover plate 110 when it is pulled out. The limiting pin 121 in the limiting portion 120 is located inside the slot 230, and the limiting block 122 is located at the top of the limiting pin 121 to play a limiting role.

[0031] For details, please refer to Figure 2 and Figure 3 The top cover plate 110 is provided with a plurality of rolling balls 150 at the bottom thereof, and the balls 150 roll on the top surface of the distribution cabinet. A removable positioning strip 140 is provided at the bottom of the top cover plate 110, and the positioning strip 140 is provided with a limiting hole for the limiting balls 150. The positioning strip 140 and the top cover plate 110 can be fixed with bolts. The balls 150 at the bottom of the top cover plate 110 roll on the top surface of the distribution cabinet, reducing friction when the top cover plate 110 moves, which means that pushing and pulling the top cover plate 110 is more labor-saving.

[0032] See also Figure 1The low-voltage switchgear isolation and protection mechanism also includes a barrier assembly 30, which surrounds the front and sides of the top cover plate 110. The barrier assembly 30 includes a front panel 310 and side panels 320. The front panel 310 is fixed to the front side of the top cover plate 110, and the two side panels 320 are respectively arranged on both sides of the top cover plate 110. The handle 130 is fixed to the front panel 310. By pulling the handle 130, the front panel 310 is moved, and the front panel 310 drives the top cover plate 110 to move. The top cover plate 110 can be fixed to the front panel 310 and the side panels 320 by welding. The front panel 310 and the side panel 320 are both used to block the rain above the top cover plate 110, preventing the rain falling on the top cover plate 110 from falling from the front and both sides of the top cover plate 110. That is, at this time, the rain on the top cover plate 110 will only fall from the back side of the top cover plate 110 and will not fall on the maintenance personnel. At the same time, it also reduces the rain falling on the maintenance personnel from splashing into the distribution cabinet.

[0033] The working principle of the isolation protection mechanism of the low-voltage switch cabinet is as follows: when in use, when performing maintenance on rainy days, the maintenance personnel hold the handle 130 at the front end of the top cover plate 110, and pull the handle 130 to drive the top cover plate 110 between the top of the distribution cabinet and the limiting strip 210 to move forward. That is, the top cover plate 110 originally located above the top of the distribution cabinet is moved to the front side above the distribution cabinet. When the operator is performing maintenance work, it can effectively reduce the possibility of external rainwater entering the interior of the distribution cabinet, and play a good protective role for the distribution cabinet. After the maintenance work on the distribution cabinet is completed, hold the handle 130 to push the top cover plate 110 to the top of the top cover plate 110 to complete the reset, reducing the space occupied by the protection mechanism and avoiding the possibility of the top cover plate 110 protruding outward and touching other objects.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
