Description

multifunctional safety fence

technical field

The utility model relates to the field of safety protection equipment in the electric power industry, in particular to a safety fence.

Background technique

At present, the installation of safety fences is one of the important technical measures to ensure the safety of on-site workers. The safety fence can not only prevent staff from entering live areas by mistake and ensure personal safety, but also effectively isolate live equipment and ensure the normal operation of electrical equipment and power grids. However, for a long time, the traditional fences used to ensure the safety of substation construction operations have no practical, safe and effective means of layout, and the warning function is often greater than the actual protection effect. question.

There are generally three types of traditional barriers in substations: wooden barriers, soft barriers, and hard barriers. During long-term use, the following disadvantages were found:

Wooden fence: mostly used indoors. The material is not corrosion-resistant and cannot be used for a long time. The shape is fixed, it is not easy to carry, and it is easy to be moved by the staff, so the safety of construction operations cannot be guaranteed.

Soft fence: mostly used outdoors. The main body of the pole is heavy, it is not easy to carry, and it is not easy to fix it on the concrete floor. When setting the warning tape, it takes a long time, and at least two or more people are required to complete it together, wasting a lot of manpower. In particular, the warning tape can be easily crossed, and it is very easy to enter the charged area by mistake, which cannot effectively protect it. In case of strong wind and thunderstorm, the pole is easy to be blown down, and the warning tape is easy to be scratched. In severe cases, the warning tape may be entangled with equipment and lines, causing major electrical safety accidents.

Hard fence: mostly used outdoors. The equipment is expensive and needs to be installed by a special person, and the installation is complicated, time-consuming and labor-intensive, and it is easy to be overtaken.

In view of these problems that arise during the use of the above-mentioned traditional barriers, they all seriously affect the safety of power equipment construction. In order to improve the safety and reliability of equipment construction, it is urgent to develop a new type of efficient and safe special fence.

Detailed ways

As shown in Figures 1, 2, and 7, the multifunctional safety fence of the present utility model includes a plurality of fence units, and the fence unit includes two columns 1 and a cross telescopic fence 2 connected between the two pillars 1, the cross telescopic fence 2 is composed of a plurality of cross bars 3 cross-connected to each other. The cross bar 3 adopts red and yellow alternate colors, which is eye-catching and has a good warning effect.

As shown in Figures 3 and 5, the column 1 includes a base 5 and a column body 4, and the column body 4 is vertically connected to the base 5; the base 5 is vertically provided with ground nail holes 11 for inserting ground nails. The base 5 is a cuboid, and the side of the column body 4 is provided with a connecting plate 6 and/or a connecting column 7 protruding from the surface of the column body 4 longitudinally. same side.

As shown in Figure 4, the connecting plate 6 is provided with one or more clamping grooves 8, the width of the clamping groove 8 is adapted to the shape of the connecting column 7, the height of the connecting plate 6 and the connecting column 7 to be connected and The positions are matched, and the clamping groove 8 of the connecting plate 6 is clamped with the connecting column 7 of the adjacent fence unit. On the one hand, the connecting plate 6 can fix the mobile fences when they are placed together, which can save the placement space; on the other hand, when the length of a single mobile fence cannot meet the requirements of use, the connecting plate 6 can firmly and reliably connect two mobile fences , fast, simple and efficient.

As shown in Figure 7, the column 1 is divided into a fixed column 21, a rotating column 22, a telescopic column 23 and a rotating telescopic column 24,

The connection relationship between the base 5 and the column body 4 of the fixed column 21 is a fixed connection or a detachable connection, and the bottom end of the column body 4 can be welded on the base 5, and the connection is reliable.

The column body 4 of the rotary column 22 is vertically and rotatably connected to the base 5, the column body 4 of the rotary column 22 is plugged in the middle position of the base 5, and the base 5 is provided with a steel pipe for clamping, corresponding to the bottom of the column body 4 The end is equipped with an opening for plugging, which is very convenient to install and disassemble by plugging;

The base of the retractable column 23 includes a base body 9 and a sliding seat 10 inserted into the base body 9 and slidably connected;

As shown in Figure 6, the base 5 of the rotating telescopic column 24 is rotatably connected to the column body 4, and the base 5 includes a base body 9 and a sliding seat 10 inserted into the base body 9 and slidably connected;

When in use, one side of the base can be rotated 360°, and one side of the base can be stretched. It can meet the problem of multi-angle layout, and it can be triangularly supported at the corner of the room, which is stronger and more economical. Used in conjunction with the anti-movement fixing nails, not only can the mobile fence be firmly fixed on various grounds, preventing it from tilting due to weather and man-made reasons, but also the possibility of placing the base at various angles can meet the safety measures of various electrical equipment. layout requirements.

An inwardly concave receiving groove 12 is provided at the joint between the column body 4 and the cross telescopic fence 2 .

The bottom ends of the column body 4 of the fixed column 21 and the rotary column 22 are connected with the middle position of the base 5 . In this way, the base 5 itself is stable, and the force of the column 1 is also stable.

As shown in FIG. 6 , the bottom ends of the body 4 of the telescopic column 23 and the rotary telescopic column 24 are connected to one end of the base body 9 . The telescopic sliding seat 10 can be retracted into the base body 9 in this way, which is convenient to be connected with the adjacent base 5, and the sliding seat 10 of appropriate length should be pulled out according to the needs of the scene to ensure the stability of the base 5.

The fence unit is connected with an infrared induction alarm 13, which is generally arranged at the entrance after forming a circle of fences. When someone is approaching, an alarm sound will be issued to make people inside and outside the guardrail find that someone is approaching the guardrail. When the maintenance site workers approach the safety fence, the infrared sensor alarm will automatically report "Stop, high voltage danger!", and the voice will remind the construction workers to prevent them from entering the high-voltage live area. When external personnel pass the entrance of the fence in the maintenance construction area, the infrared sensor alarm will automatically report "has entered the work area, please pay attention to safety". Compared with the "Stop, high voltage danger!" related signboard printed on the traditional warning tape, the infrared sensor alarm can give the staff a more intuitive warning, which greatly prevents the occurrence of safety accidents.

The connecting column 7 is square or cylindrical, and the shape is set according to needs.

The cross telescopic bar 2 is provided with a hook 14, which is used for hanging warning signs or banners, etc., without looking for tools or materials in addition. Sometimes some people use iron wires to hang warning signs, which is very dangerous because of the potential for electric shock.

Cross telescopic fence 2 is provided with reflective strip, is convenient to dark place or the position of guardrail is found by the near personnel at night.

The outer side of the column 1 can be connected with a magnet. When the outer side of the column 1 is close to the door or cabinet body of the iron switch cabinet, it can be directly absorbed by the magnetic force, which is more stable.

The material of cross bar 3 is epoxy resin and fiberglass fiber. The material is light, easy to move, and the strength also meets the requirements.

When transporting the utility model, it can be reloaded with a dolly and fixed on the car with a strap.

Advantage of the utility model:
