Abstract
The utility model discloses an electric approaching alarm device for live-line maintenance of a high-tension line, solving the problem that a maintainer can not accurately determine the distance from a live wire while replacing insulator strings on a middle cross arm and a lower cross arm of the live-line high-tension line. The electric approaching alarm device comprises an elliptical horizontal frame (1), a hook (2) arranged at the center of the elliptical horizontal frame (1), a sound alarm (7) arranged on the elliptical horizontal frame (1), a first distance sensor (6), a second distance sensor (3), a third distance sensor (4) and a fourth distance sensor (5), wherein the first distance sensor (6) is arranged at the center point of the elliptical horizontal frame (1) and has a probe facing downwards; the second distance sensor (3), the third distance sensor (4) and the fourth distance sensor (5) are arranged on the elliptical edge of the elliptical horizontal frame (1) at an interval, and have a probe facing downwards, respectively; and the four distance sensors are electrically connected with the sound alarm (7), respectively. The electric approaching alarm device provided by the utility model is simple in structure, convenient in carrying and use, and particularly suitable for use in the construction field of the high-tension line.
Description
Technical field
The utility model relates to a kind of warning device, particularly a kind of being arranged on the charged high-tension line the device near charging zone personnel audible alarm.
Background technology
The arrangement mode of the pylon construction of line has cross-arm horizontal; Cross-arm is homeotropic alignment and the cross-arm three kinds of modes that are triangularly arranged up and down; The cross-arm mode of homeotropic alignment up and down is that three cross-arms in upper, middle and lower are arranged on an iron tower; On each cross-arm, be provided with insulator string, the insulator string period of the day from 11 p.m. to 1 a.m in charged for replacement on cross-arm and the following cross-arm, the maintainer need climb to the manual coupling bolt of removing cross-arm and insulator on the cross-arm.In whole construction course and since the maintainer can not accurately judge with the crown on the distance of live wire, electric shock accidents takes place easily.
Summary of the invention
The utility model provides a kind of high-tension line hotline maintenance alarming in short range of electric power device, has solved in charged high-tension line the is changed insulator string period of the day from 11 p.m. to 1 a.m maintainer on the cross-arm and following cross-arm and can not accurately judge the problem with the live wire spacing.
The utility model overcomes the above problems through following scheme:
A kind of high-tension line hotline maintenance alarming in short range of electric power device; Comprise oval level frame; Center at oval level frame is provided with suspension hook; Oval level frame is provided with voice guard; Central point at oval level frame is provided with the first downward range sensor of probe, and the compartment of terrain is respectively arranged with the downward second distance sensor of probe, downward the 3rd range sensor and the 4th downward range sensor of popping one's head in of probe on the elliptical side of oval level frame, and first range sensor, second distance sensor, the 3rd range sensor and the 4th range sensor are electrically connected with voice guard respectively.
Second distance sensor, the 3rd range sensor and the 4th range sensor are that uniformly-spaced radian is provided with on the elliptical side of oval level frame.
The utility model is simple in structure, portably uses conveniently, is particularly suitable for the high-tension line working-yard and uses.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Specific embodiment
A kind of high-tension line hotline maintenance alarming in short range of electric power device; Comprise oval level frame 1; Be provided with suspension hook 2 in the center of oval level frame 1; Oval level frame 1 is provided with voice guard 7; Be provided with the first downward range sensor 6 of probe at the central point of oval level frame 1, the compartment of terrain is respectively arranged with the 3rd downward range sensor 4 of the downward second distance sensor 3 of probe, probe and pop one's head in downward the 4th range sensor 5, the first range sensors 6, second distance sensor 3, the 3rd range sensor 4 and the 4th range sensor 5 are electrically connected with voice guard 7 respectively on the elliptical side of oval level frame 1.
The utility model is hung on the last cross-arm or middle cross-arm of the high voltage supply iron tower directly over the workmen construction; As workmen during near charging zone; Range sensor will be passed to voice guard 7 with signal, and voice guard 7 sends alarm sound, reminds the workmen to note Danger Electric shock risk.
