Description

Guard for ground device

In general, the power system equipment such as transformers or switchgear installed on the ground to control the underground distribution line is called the ground equipment, and is housed in a box-type enclosure.

In the case of the installation of power system equipments such as telephone poles and overhead wires, there are problems such as impairing the aesthetics of the city and uncomfortable traffic, and in recent years, these facilities have been underground to prevent exposure to the ground.

In this way, the ground equipment is installed on the ground in the process of undergrounding the power system.In this case, the ground equipment is installed close to the boundary stone on the sidewalk so as not to obstruct pedestrians' traffic, and the ground equipment is not damaged by vehicle collision. Install a guard to

Conventional protection is composed of a rectangular frame by connecting a plurality of vertical posts and the horizontal bar in an orthogonal state and then bent at both ends of the horizontal bar at a right angle, the vertical post of the body to surround the front and both sides of the ground equipment The lower ends of both sides of the ground will be installed.

These guards do not consider any shock absorbing function that can alleviate the impact when a collision occurs due to inadvertent driving of the vehicle. In the event of a severe impact, the transformer or switch could be damaged.

In addition, when the door of the ground equipment is placed facing the road, the front surface is covered by the vertical post and the horizontal bar. Whenever the transformer or the switch is operated, the ground equipment must be pushed backward by the width of one door and opened after the door is opened. There was an inconvenience.

On the other hand, it is known as the patent No. 516440 to solve the inconvenience in the installation work of the guard as described above.

The patent invention is a ground apparatus for protecting the ground equipment placed on the base by crossing the horizontal bar on a plurality of vertical posts from external impact or collision, the lower end of the vertical post toward the base A bent portion is provided, and the bent portion is provided with a flange extending to the side wall of the base and fixedly coupled to the side wall of the base.

Such a guard is fixed by screwing a flange of a bent portion bent at the lower end of the vertical post to the side wall of the foundation. In the installation work of the protection post, it is simple compared to embedding the lower end of the conventional vertical post on the ground, but it is heavy. The flange formed at the tip of the bend of the lower end of the vertical post is fixed to the side wall of the base by screwing, that is, the bolt-nut is tightened, so that the fixing part is not strong and the fixing state is weak enough to swing back and forth in the small impact. Therefore, the vehicle is easily damaged or collapsed from the collision of the vehicle, causing damage to the ground equipment, and thus it is not practically used as a problem in that it cannot properly perform its function as a protective body.

In addition, the conventional guards have a structure that completely blocks the roadway direction despite the structure that can be opened in the driveway direction of the ground equipment, there was a restriction that the ground equipment must be installed so that the door to the delivery direction.

Therefore, an object of the present invention is to provide a structure that combines protection and opening / closing functions for the case where the doors of the ground equipment are installed to open in the direction of the roadway, while absorbing and relieving the shock when the vehicle collides to prevent damage to the ground equipment. It is to provide protective equipment for ground equipment that can be protected.

The object of the present invention is to provide a ground protection device for protection of ground equipment which connects vertical posts and horizontal bars in an orthogonal state, and then embeds both lower ends of the vertical posts on the ground of both sides of the ground equipment. On the front vertical posts of the two side guards, a buffer band protruding to the front on the front extension line of the upper horizontal bar, and the front protection at the opposite positions inside the upper extension of the vertical posts located on the driveway side of the two side guards, respectively. A bracket having a hinge shaft for inducing the opening and closing of the stand and a bracket for closing the front guard by the fastening of the bolt-nut are attached to the hinge shaft of one of the brackets attached to the inner opposite position of the upper extension of the vertical post. Tighten one end of the front guard and bolt the nut on the other end of the front guard. It can be achieved as surface protective device for protection to be closed by tightening.

The protective device for ground equipment protection according to the present invention has a structure having both a protective function and an opening / closing function, and when the accident occurs due to drowsiness or carelessness of a vehicle driver driving on a roadway, By absorbing and mitigating shocks, ground equipment can be protected from impacts such as vehicle crashes.

The present invention as described above, after connecting a plurality of vertical posts and horizontal bars installed so as to surround the front and both sides of the ground equipment placed on the base frame in an orthogonal state, both sides of the bottom of the vertical post both sides of the ground equipment It is based on a protective equipment for ground equipment embedded in the ground.

In the protective device for such a ground apparatus, the present invention, as shown in Figures 1 to 4, a vertical post for protecting both sides of the ground apparatus (1) and the front vertical post of the side guard (11) consisting of a horizontal bar On the front extension line of the upper horizontal bar is installed so as to project the buffer 12 to the front.

The buffer 12 is formed in a straight line, protrudes from the side guard 11 in the driveway direction in the driveway serves to absorb and mitigate shocks when the vehicle crashes.

In the present invention, the side guard 11 is to bury the lower end (11a) of the vertical post on both grounds of the ground equipment (1), it is different from the usual to bury the lower end (11a) of the vertical post on the ground none.

Although the vertical post and the horizontal bar constituting the side guard 11 are shown as circular tubes, that is, circular pipes in the figure, square pipes may be used, and either side may be selectively used.

A bracket is attached to the front vertical post of the side guard 11, that is, the upper extension part 11b of the vertical post located on the side of the roadway, to enable the opening or closing of the front guard 13 described later. .

The front guard 13 of the present invention is to enable the opening and closing toward the driveway direction when opening and closing the door 2 of the ground equipment (1) also serves as the front protection of the ground equipment (1).

The front guard 13 is installed in the bracket 11c attached to the opposite position inside the upper extension portion 11b of the vertical post located on the driveway side of the both side guards 11, the bracket 11c. Either bracket (11c) is used as a hinge shaft for inducing opening and closing of the front guard 13, the other bracket (11c) to close the front guard 13 by the bolt-nut fastening. do.

Both opposing brackets 11c are located at both ends of the front guard 13 and share the hinge axis and the closing role, respectively, but the roles of the front and rear guards 13 are not changed. There is no effect.

In the protective device for protecting ground equipment according to the present invention configured as described above, the front guard 13 is usually on the opposite bracket 11c inside the upper extension 11b of the vertical post of the two side guards 11. One end is rotatably supported by the hinge shaft, and the other end is kept closed by closing the bolt-nut.

As described above, when the front guard 13 is closed and the roadway direction is blocked, the front guard 13 can perform a function as a guard that can protect the ground apparatus 1 from an impact such as a vehicle collision.

When the operator opens and closes the door 2 for the operation or maintenance of the ground equipment 1 in this state, as shown in FIG. 4, the bolt-nut is removed from the bracket 11c at one end of the front guard 13 described above. Loosen and pull the front guard 13 in the driveway direction, rotate the hinge shaft fastened to the bracket 11c at the other end to the pivot point, and open it to secure enough space for opening and closing the door 2 of the ground equipment 1. The opening and closing door 2 of the ground equipment 1 may be opened.

The protective equipment for ground equipment protection is determined according to the installation position of the ground equipment 1, and the ground equipment 1 is generally installed at a position close to the boundary between the sidewalk and the roadway in India.

Therefore, the installation position of the guard is installed on the side of the road where the ground apparatus 1 is installed, that is, on the side of the side of the side of the sidewalk just inside the boundary between the sidewalk and the roadway.
