Abstract
An electric transmission line concrete pole welding joint anticorrosion protection device is composed of semi-circular cylindrical surface protective covers (1), seal rings (2) and a fastening lock catch (3). The fastening lock catch is installed on the edge of a straight line of each semi-circular cylindrical surface protective cover (1). Square grooves are machined at the upper end and the lower end of the inner surface of each semi-circular cylindrical surface protective cover (1). The seal rings with the rectangular cross sections are embedded into the grooves in the inner surface of the upper end and the lower end of each semi-circular cylindrical surface protective cover to evenly screw down the protective cover fastening lock catch (3). Two left-and-right symmetrical semi-circular cylindrical surface protective covers (1) are folded to tightly wrap a welding line of the concrete pole. According to the electric transmission line concrete pole welding joint anticorrosion protection device, the occurrences of corrosion destruction on the welding line of the electric transmission line concrete pole and metal in a weld heat-affected zone by various corrosion gases, ultraviolet rays, ice, frost, and rainwater outside are effectively prevented, and the anti-corrosion ability of the concrete pole welding line and the weld heat-affected zone is improved. The electric transmission line concrete pole welding joint anticorrosion protection device is suitable for protecting the electric transmission line concrete pole and the converting station concrete framework welding line.
Description
Technical field
The utility model relates to a kind of electric transmission line concrete pole weld seam antisepsis protector, belongs to ultra-high-tension power transmission line operation maintenance maintenance equipment technology field.
Background technology
The concrete bar is requisite important component in transmission and distribution network, the transformer station, anticorrosion at ultra-high-tension power transmission line operation maintenance maintenance equipment technology field concrete bar weld seam is the important leverage of electric line safety in production, and its safe operation is directly connected to the safety and stability of electrical network and to the reliability of customer power supply.
And the exposed corrosion that is subject to various corrosive gas in the atmosphere, ultraviolet ray and frost rainwater of general concrete bar weld seam.Use the present invention will effectively prevent the weld corrosion of concrete bar, thereby avoid serious because of the weld corrosion of concrete bar, mechanical strength descends, weld cracking, and make electric transmission line concrete pole fall bar, and cause the generation of large area blackout, effectively ensure the transmission and distribution network safety in production.
Summary of the invention
The purpose of this utility model is, in order to promote the antiseptic property of concrete bar weld seam, ensures the safety of electric transmission line concrete pole, and the present invention discloses a kind of electric transmission line concrete pole weld seam anti-corrosive apparatus.
The technical solution of the utility model is; utilize internal diameter the protective device with upper-lower seal circle identical with concrete bar external diameter; in order to isolate extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal are destroyed; promote the Corrosion Protection of concrete bar, thereby reach the long-lived purpose of concrete bar.
The described protective device of the inventive method is comprised of semicircle cylinder protective cover, sealing ring and fastening snap close; Fastening snap close is installed on the semicircle cylinder protective cover linear edge, and semicircle cylinder protective cover inner surface is processed with square groove in two ends up and down; The cross section is that the sealing ring of square type embeds semicircle cylinder protective cover up and down in the inner surface recesses of two ends, evenly tightens the fastening snap close of protective cover, and two symmetrical semicircle cylinder protective covers close up and tightly wrap up concrete bar weld seam; Described device has effectively been isolated extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal has been destroyed, and has promoted concrete bar weld seam and weld heat-affected zone anticorrosive metal performance.
The beneficial effects of the utility model are, do not adopt the exposed weld seam of concrete bar of concrete bar weld seam antisepsis protector to compare with other, the concrete bar weld seam anti-corrosion protection cover that concrete bar weld seam antisepsis protector of the present invention forms has following characteristics: 1. to concrete bar weld seam omnibearing protection, reduce ultraviolet ray and frost rainwater to the erosion of concrete bar weld seam; 2. reduce in the atmosphere various corrosive gas to concrete bar weld seam and weld heat-affected zone corrosion of metal; 3. mounting method is simple, rapid.This method is simple and easy to do, protective device is installed rapidly.The utility model is obvious to the anticorrosion ability of electric transmission line concrete pole weld seam and weld heat-affected zone metal.Can effectively prevent concrete bar weld corrosion cracking and cause electric transmission line concrete pole to fall bar, the large area blackout of initiation improves electrical network power transmission and distribution safety in production level.Simultaneously, reduce the negative effect that large-area power-cuts produces all sectors of society.On the other hand, the utility model protective device is simple in structure, selects materials easy and durable, and reliability is also very high.
The utility model is applicable to the protection to electric transmission line concrete pole and transformer station's concrete framework weld seam.

The specific embodiment
The specific embodiment of the present utility model as shown in Figure 1 and Figure 2.
The utility model embodiment adopts concrete bar weld joint protective device that the electric transmission line concrete pole weld seam is protected.
The utility model examples of implementation concrete bar weld joint protective device is comprised of semicircle cylinder protective cover 1, sealing ring 2 and fastening snap close 3; Semicircle cylinder protective cover 1 is processed by cast aluminium, the interior radius of circle of semicircle cylinder protective cover 1 is identical with concrete bar external diameter, two ends are along being processed with the square groove vertical with semicircle cylinder on the inner arc surface up and down for semicircle cylinder protective cover 1 inner cylinder face, and fastening snap close is installed on the semicircle cylinder protective cover linear edge; Be that the sealing ring 2 of square type embeds semicircle cylinder protective cover about in the of 1 in the inner surface recesses of two ends with the cross section; evenly tighten the fastening snap close 3 at semicircle cylinder protective cover 1 edge; protective device is tightly wrapped up concrete bar weld seam; effectively isolate extraneous various corrosive gas, ultraviolet ray and frost rainwater electric transmission line concrete pole weld seam and weld heat-affected zone corrosion of metal have been destroyed, promoted concrete bar weld seam and weld heat-affected zone anticorrosive metal performance.The first butt welded seam external coating rustproof paint of palpus before concrete bar weld joint protective device is installed after antirust the doing, is installed concrete bar weld joint protective device, has avoided the oxide etch of a small amount of air butt welded seam of retention, can protect better weld seam to avoid corrosion.
