Description

A kind of concrete bar anti-theft device
Technical field
The utility model belongs to electrical equipment technical field, relates to a kind of concrete bar anti-theft device particularly.
Background technology
Electric power concrete pole, also known as making electric pole, is used to the concrete body of rod installed electric wiring, and should be noted that and carry out anti-theft protection during actual use.First, the circuit in order to avoid erection runs into lightning stroke trip, line-outage contingency occurs, and improves the reliability of power supply, on concrete bar, is usually provided with lightning arrester carries out lightning protection.Lightning protection needs, by lead-in wire, lightning current is introduced the earth, and the subject matter existed at present is the situation that lead-in wire is stolen that often occurs, thus when causing thunderstorm weather, stolen rear remaining lead-in wire forms short circuit, causes trip accident, jeopardizes personal safety time serious; Secondly, except having the situation of stealing lightning protection lead-in wire, also there is the problem of stealing earth electrode joint in the concrete bar of existing installation.According to power industry standard, the method that concrete rod grounded pole joint is with bolts, does not almost have anti-theft feature.Traditional mode overwhelming majority adopts the mode of Anti-theft cap to carry out antitheft, and some adopts the mode of welding, although meet antitheft requirement, does not meet the requirement of technical regulation, so be not general method in power industry.And but the mode of the built-in ground connection of earth electrode joint is subject to the restriction of geographical position and shaft tower environment, how solves the extremely antitheft problem of tower grounding, just become the task of top priority.
Summary of the invention
The utility model is to solve the problems of the technologies described above, and provides a kind of and can avoid lightning protection lead-in wire and the stolen concrete bar anti-theft device of earth electrode joint.
The technical solution of the utility model is: a kind of concrete bar anti-theft device, comprise concrete bar, the upper end of described concrete bar is provided with patch bay, patch bay is provided with lightning arrester, lightning arrester is connected with connecting line, the lower end of described concrete bar is connected with earth electrode protection of welded joints block, described earth electrode protection of welded joints block is inverted T-shape, earth electrode protection of welded joints block comprises vertical part and lateral part, the outside of lateral part is provided with acclivitous brace, one end that vertical part is positioned at more than ground is provided with builds mouth, one end that vertical part locates below ground level and lateral part are connected, the outside of concrete bar is provided with connecting line protective frame, the upper end of connecting line protective frame is connected with patch bay, the lower end of connecting line protective frame is connected with vertical part, the middle part of connecting line protective frame is connected with warning sign by warning sign support.
Preferably, described brace lateral part outside circumferentially on be evenly arranged.
Further, the outside of described lateral part is provided with two rows brace vertically.
Further, the angle of inclination of described brace is 45 degree.
Further, described two rows brace be arranged in parallel.
Further, described two rows brace interlaced arrangement.
The beneficial effects of the utility model are: first, by arranging earth electrode protection of welded joints block, first earth electrode joint is put in the lower end of concrete bar during installation, then from building mouth to casting concrete in earth electrode protection of welded joints block, thus concrete bar, built on stilts downlead and connector are formed integrative-structure, be connected firmly, both met antitheft needs, the requirement of earth resistance can be met again; In addition, in order to improve anti-theft effect, earth electrode protection of welded joints blocks design being become inverted T-shape structure, namely comprising the lateral part of the narrower vertical part of width and wider width, during installation, below ground is put in lateral part larger for width, and acclivitous brace is set in its periphery.When have people to steal joint upwards pull up concrete bar time, be positioned at soil above brace and lateral part to increase resistance, thus can effectively avoid joint to be stolen.
Secondly; in concrete bar outer setting connecting line protective frame; the connecting line of lightning protection is placed in protective frame; the personnel of stealing can be avoided arbitrarily to cut connecting line; the connecting line exposed problem occurring lightning current ability of the drawing decline that corrosion causes outside for a long time can be avoided simultaneously; and then thunderstorm weather generation trip accident can be avoided, improve the fail safe used.Meanwhile, connecting line protective frame arranges warning sign, nearby to play the potential safety hazard caused to avoid personnel.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of concrete bar anti-theft device of the present utility model, comprise concrete bar 1, the upper end of concrete bar 1 is provided with the patch bay 4 for the construction of line, particularly, the quantity of patch bay 4 is three, and three patch bays are arranged from top to bottom successively along concrete bar in the vertical direction, is used for respectively setting up three-phase line.Patch bay 4 is provided with the lightning arrester 2 for lighting protection, lightning current is introduced the earth by connecting line 3 by lightning arrester 2.Particularly, connecting line 2 extends layout downwards along concrete bar, within one week, is provided with connecting line protective frame 5 in connecting line 2 external rings around concrete bar, is used for protecting connecting line stolen.Connecting line protective frame 5 can be made up of steel plate turnup, also can be arranged to railing type structure, and its lower end is fixed on earth electrode protection of welded joints block 8, and upper end is fixed on patch bay 4.Be connected with warning sign 7 at the middle part of connecting line protective frame 5 by warning sign support 6, be used for warning through neighbouring personnel, avoid its potential safety hazard caused of playing around.
The earth electrode protection of welded joints block 8 in inverted T-shape is provided with in the lower end of concrete bar 1, particularly, earth electrode protection of welded joints block 8 makes external frame by steel plate or plank etc., framework leaves and builds mouth 9, to be integrally fixed to casting concrete in framework thus by concrete bar and protective block structure by building mouth during installation, be connected firmly, joint can be avoided stolen.
Earth electrode protection of welded joints block 8 comprises the lateral part 82 of the narrower vertical part 81 of width and wider width, during installation, below ground is put in lateral part 82, a part for vertical part 81 is basseted to build mouth 9 for setting and complete concrete building.Particularly, lateral part 82 outside circumferentially on be evenly arranged multiple brace 10 of 45 degree of being inclined upwardly, in order to increase effect resistance, two rows brace 10 is provided with vertically in the outside of lateral part 82, two rows brace 10 can be arranged in parallel also can interlaced arrangement, be used for strengthening the bonding strength on protective block and ground, and then resistance when joint is stolen in increase, can anti-theft effect be improved.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
