Technical Field

The invention relates to a power transmission device, in particular to an overhead insulated cable fixing seat.

Background

The electric energy is an energy form which is economic, practical, clean and easy to control and convert, is widely applied to various fields of power, illumination, chemistry, textile, communication, broadcasting and the like, and is the main power for scientific and technical development, economic development and people's life. In the existing power transmission, a 10 kv high-voltage line is transformed into a 380 v three-phase four-wire low-voltage cable, and then the cable reaches each power consumer (enterprise or residential area) through an overhead line supported by a power pole, and then a three-phase four-wire cable is led out from the overhead cable and extends downwards to a switch end of the power consumer. However, the power transmission line led out from the overhead cable needs to be operated aloft, so that the labor intensity is high, the working efficiency is low, and potential safety hazards are caused.

Disclosure of Invention

The invention aims to overcome the defects of the background technology and provides the overhead insulated cable fixing seat which has the characteristics of convenience in operation, high working efficiency and reduction of potential safety hazards in construction.

The technical scheme provided by the invention is as follows:

The utility model provides an overhead insulated cable fixing base which characterized in that: the fixing seat comprises a seat body, at least one groove which is manufactured at the top end of the seat body and used for accommodating a cable, and a cover plate which is positioned in a groove opening through a fastener so as to clamp and embed the cable in the groove; the bottom end of the seat body is provided with a bottom plate extending out towards the two sides of the width direction, so that the cross section of the seat body forms an inverted T shape, and the bottom plate is provided with a plurality of through holes for inserting expansion bolts, so that the fixed seat can be fixed on the wall of a street building.

The through hole is a waist-shaped hole, and the long axis direction of the waist-shaped hole is parallel to the length direction of the seat body.

The fixing seat is provided with a through hole which transversely penetrates through the seat body and is used for fixedly penetrating the cable supporting wire.

The framework of the fixing seat is made of steel, and the framework is completely coated by the injection molding layer, so that an insulating device is formed.

One of the openings at both ends of each cover plate penetrates through the edge of the cover plate, thereby forming a hook-shaped opening.

The invention has the beneficial effects that:

By adopting the invention, the installation work of the transmission cable is obviously simplified, the telegraph pole does not need to be buried, the high-altitude operation is not needed, the potential safety hazard is eliminated, the installation work efficiency is greatly improved (by 3-4 times), and the installation work cost is reduced (the telegraph pole does not need to be manufactured, and the telegraph pole does not need to be buried by excavation); is popular with the relevant power units.

Detailed Description

In the aerial insulated cable fixing seat shown in the figure, a bottom plate 6 extending out of two sides in the width direction is manufactured at the bottom end of a seat body 1, so that the cross section of the seat body forms an inverted T-shaped structure; at least one groove 2 (2 grooves are shown in the figure) for accommodating cables is formed at the top end of the seat body, and each groove is suitable for the diameter of a power transmission cable (the seat body can be manufactured into fixed seats with different specifications and is respectively suitable for cables with different specifications); the cover plates 4 are positioned in the groove notches (the two ends of each cover plate are provided with openings through which the bolts pass) through fasteners 3 (preferably bolts; fastening nuts can be matched) so as to clamp and embed the cables in the grooves for installation and positioning. A plurality of through holes 6 are formed in the bottom plate, and expansion bolts can be inserted into the through holes, so that the fixing seat is fixed on the wall of a street building.

In addition, the fixing seats are provided with through holes 5 which transversely penetrate through the seat body, and the cable supporting wires can be sequentially connected and fixed in the through holes of the fixing seats in a penetrating manner, so that the supporting wires are formed; in addition, the cable hanging between the adjacent fixed seats is hung on the supporting wire through a metal hook (usually a steel wire hook), so that the radian of the cable hanging is reduced.

Furthermore, the through hole is a waist-shaped hole, and the long axis direction of the waist-shaped hole is parallel to the length direction of the seat body.

So as to facilitate the installation of the fixed seat.

Further, one of the openings at both ends of each cover plate penetrates through the edge of the cover plate, thereby forming a hook-shaped opening 4-1; when the cable pulling device is used, bolts do not need to be taken down from the fixed seat, and the cover plate can be swung around the bolt axis to move away only by loosening the bolts at two ends (the hook-shaped opening is transversely separated from the fixed bolt, so that the cover plate swings around the bolt axis at the other end), so that the cable is embedded into the groove or pulled out of the groove; when the cover plate is fixed, only the cover plate needs to be swung, one end of the hook-shaped opening can be embedded into the bolt, and then the nut is screwed down. Brings great convenience to the installation and maintenance work.

Still further, the skeleton of fixing base is steel, and the skeleton outside is by the complete cladding of layer of moulding plastics to form an insulating apparatus.

The working principle of the invention is as follows: when the fixing seat is installed, the bottom plate of the fixing seat is only required to be attached to a wall surface with a proper height (usually about 2.5 meters) of a street building, and the length direction of the bottom plate is vertical to the ground; then inserting the expansion bolts into the waist-shaped holes in a penetrating way and screwing and fixing the expansion bolts; and then, the cable is embedded into the groove of the fixed seat, and finally, the cover plate is covered and the fixing bolt of the cover plate is screwed, so that the cable of one fixed seat can be installed. According to the method, fixing seats (the distance between every two adjacent fixing seats is proper; usually the distance is less than 5 m) are respectively installed on the same building or the wall surfaces of the adjacent buildings at the same height on the street, and the same cable is sequentially fixed on the fixing seats, so that the installation and the positioning of the cable can be completed. In addition, the hanging steel wire rope can sequentially penetrate through the through holes on the fixing seats and form a supporting line after being tightened and fixed, and then the cable is hung on the steel wire rope by adopting a plurality of hooks between every two fixing seats so as to reduce the suspension radian of the cable.
