In addition, in the later use process, the power maintenance personnel can also determine whether the pole tower body is tilted by checking whether the connecting rope is in contact with the limit tube, which is more intuitive and reliable.

[0021] 2. In the utility model, by coordinating the adjustment seat, the adjustment ball and the fixing knob, for a pole tower body that does not need to be installed vertically, the inclination angle of the limit tube can be adjusted according to the expected installation angle of the pole tower body to ensure that the limit tube is in a vertical downward position when the pole tower body is installed; specifically, by loosening the fixing knob, the adjustment ball can keep the limit tube vertically downward under the action of the counterweight ball, and then the fixing knob can be tightened. Similarly, power maintenance personnel can also determine whether the pole tower body is tilted in a manner other than that originally installed by checking whether the connecting rope is in contact with the limit tube.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example: Reference Figure 1-5 An overhead power distribution line shown includes a tower body 1, a detection component 2, a fixing component 3 and a connecting component.

[0031] Among them, the detection component 2 includes a limiting tube 21, a connecting rope 22 and a counterweight ball 23. The connecting rope 22 is located on the inner side of the limiting tube 21 and coincides with the axis of the limiting tube 21. The lower end of the connecting rope 22 is fixed to the counterweight ball 23. The fixing component 3 can be detachably fixed to the outer side of the tower body 1. The upper ends of the limiting tube 21 and the connecting rope 22 are connected to the fixing component 3 through the connecting component.

[0032] The detection component 2 is fixed to the side end of the tower body 1 by using the fixing component 3, so that the limiting tube 21 is parallel to the tower body 1. When installing the tower body 1, whether the tower body 1 is vertical can be determined by observing whether the connecting rope 22 is in contact with the limiting tube 21. Since the inner diameter of the limiting tube 21 is relatively small, as long as the connecting rope 22 is not in contact with the limiting tube 21, the tower body 1 can be assumed to be in a vertical state, which is convenient for vertical judgment when the tower body 1 is installed. In addition, in the later use process, the power maintenance personnel can also determine whether the tower body 1 is tilted by checking whether the connecting rope 22 is in contact with the limiting tube 21, which is more intuitive and reliable.

[0033] Among them, the connecting parts include an adjusting seat 25, an adjusting ball 26 and a fixing knob 27. The adjusting seat 25 is fixed to the side end of the fixing part 3. The lower end of the adjusting seat 25 is provided with a limiting ball groove 2501 for movably installing the adjusting ball 26. The limiting tube 21 and the connecting rope 22 are both fixed on the adjusting ball 26. The fixing knob 27 is threaded through the adjusting seat 25 and abuts against the adjusting ball 26.

[0034] In the case of a pole tower body 1 that does not need to be installed vertically, the inclination angle of the limiting tube 21 can be adjusted according to the expected installation angle of the pole tower body 1 to ensure that the limiting tube 21 is in a vertical downward position when the pole tower body 1 is installed. Specifically, the fixing knob 27 can be loosened, and the adjusting ball 26 can keep the limiting tube 21 vertically downward under the action of the counterweight ball 23, and then the fixing knob 27 can be tightened. Similarly, the power maintenance personnel can also determine whether the pole tower body 1 is tilted in a manner other than the original installation by checking whether the connecting rope 22 is in contact with the limiting tube 21.

[0035] Among them, the detection component 2 also includes a protective cover 24, and the protective cover 24 is a transparent cover body. The protective cover 24 is arranged on the outside of the limiting tube 21, the connecting rope 22, the counterweight ball 23 and the adjustment seat 25. The protective cover 24 is connected to the fixed component 3. The protective cover 24 can play a good protective role on the structure inside it, so that the internal structure is not easily affected by the external environment, and the protective cover 24 made of transparent material is convenient for personnel to check whether there is contact between the connecting rope 22 and the limiting tube 21.

[0036] Among them, the fixing component 3 includes a fixing clamp 31, a fixing bolt 32 and a mounting seat 33. The fixing clamp 31 is fixed to the outside of the tower body 1 by the fixing bolt 32. The mounting seat 33 is integrated at the side end of the fixing clamp 31. The adjustment seat 25 and the protective cover 24 are both connected to the lower end of the mounting seat 33. An elastic rubber pad is arranged on the inner wall of the fixing clamp 31, which can adapt to the tower body 1 of similar size.

[0037] In order to facilitate the adjustment of the inclination angle of the limiting tube 21 according to actual usage requirements, a threaded ring 2401 is integrated at the upper end of the protective cover 24, and an annular threaded groove 3301 that is threadedly matched with the threaded ring 2401 is provided at the bottom end of the mounting seat 33, so as to facilitate the disassembly and replacement of the protective cover 24.

[0038] Working principle of the utility model: the detection component 2 is fixed to the side end of the pole tower body 1 by using the fixing component 3, so that the limiting tube 21 is parallel to the pole tower body 1. When installing the pole tower body 1, it can be determined whether the pole tower body 1 is vertical by observing whether the connecting rope 22 is in contact with the limiting tube 21. Since the inner diameter of the limiting tube 21 is small, as long as the connecting rope 22 is not in contact with the limiting tube 21, the pole tower body 1 can be assumed to be in a vertical state, which is convenient for the vertical judgment when the pole tower body 1 is installed; in addition, in the later use process, the power maintenance personnel can also determine whether the pole tower body 1 is tilted by checking whether the connecting rope 22 is in contact with the limiting tube 21, which is more intuitive and reliable;

[0039] In the case of a pole tower body 1 that does not need to be installed vertically, the inclination angle of the limiting tube 21 can be adjusted according to the expected installation angle of the pole tower body 1 to ensure that the limiting tube 21 is in a vertical downward position when the pole tower body 1 is installed. Specifically, the fixing knob 27 can be loosened, and the adjusting ball 26 can keep the limiting tube 21 vertically downward under the action of the counterweight ball 23, and then the fixing knob 27 can be tightened. Similarly, the power maintenance personnel can also determine whether the pole tower body 1 is tilted in a manner other than the original installation by checking whether the connecting rope 22 is in contact with the limiting tube 21.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
