Description

Windshield for substation

technical field

The utility model belongs to the technical field of safety protection of substations, and relates to a windproof shelter for substations.

Background technique

Before carrying out relevant work in the outdoor substation equipment area of the substation, the substation operation and maintenance personnel need to take relevant safety measures, and use mobile hard barriers to isolate live equipment and non-live equipment to prevent relevant staff from entering the live interval by mistake. An electric shock accident occurred. In actual work, in case of strong winds, the mobile hard screen set by the operation and maintenance personnel will fall over due to the strong wind. The test found that the side fall rate of the screen under the third and fourth winds is 100%. It usually takes 5-10 minutes from the time when the barrier is set up to the occurrence of side fall, which will lead to the failure of safety measures, and then there is a potential safety hazard for the on-site staff to cross the safety measures and enter the live interval. In view of the phenomenon that the shelter is easy to fall, heavy objects (such as masonry) are usually used to press the bottom of the shelter. This method can prevent the shelter from falling to a certain extent, but it is time-consuming and laborious, and the heavy object is easy to cause damage to the bottom of the shelter.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the windproof shelter for substations provided by the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

In the description of the present invention, it should be understood that the terms "center", "horizontal", "longitudinal", "front", "rear", "left", "right", "upper", "lower", The orientations or positional relationships indicated by "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility. The novel and simplified description does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the scope of protection of the present invention.

As shown in FIG. 1 , the present invention provides a windproof screen for a substation, which includes a screen body 1 and two brackets. The screen body 1 adopts an existing prismatic retractable screen, which is located between the two brackets and is connected by screws or It is fixed on two brackets by welding.

As shown in FIG. 1 , the bracket includes a vertical rod 2 and a retractable horizontal rod 3 , which are arranged perpendicular to each other. The retractable horizontal rod 3 is composed of a fixed rod 31 and two sliding rods 32.

The vertical rod 2 adopts a rectangular rod-shaped structure, or I-beam. The bottom of the vertical rod 2 is fixed at the top center of the fixed rod 31 by the "L"-shaped mounting piece 21 and the screw 22 , and the vertical rod 2 can also be welded on the fixed rod 31 .
