Examples

As shown in fig. 1, the present embodiment discloses a lightning rod detection device, which can be used to detect the perpendicularity of a straight rod type lightning rod, specifically, the lightning rod detection device includes a vertical rod 1, a leaning structure, a take-up pulley 6, a suspension wire 4, a weight block 11 and a scale rod 5. The vertical rod 1 is a cylindrical straight rod with uniform vertical size, is connected to the vertical rod 1 through a leaning structure, and is perpendicular to the vertical rod 1. The scale rod 5 is also connected to the vertical rod 1 and is positioned on the side opposite to the abutting structure, and the scale rod 5 is also vertical to the vertical rod 1; the scale rod 5 is provided with length scales. The take-up pulley 6 is arranged at the top end of the vertical rod 1 through the mounting frame 7; the mounting bracket 7 comprises two mounting panels and a pivot, and two mounting panels relatively fixed are at the top of montant 1, and two mounting panels are then passed to the pivot, and take-up pulley 6 is installed in the pivot, therefore the take-up pulley can rotate. The suspension wire 4 is wound on the take-up pulley 6, and the balancing weight 11 is bound at the end part of the suspension wire 4. When the take-up pulley 6 is rotated in the forward and backward directions, the suspension wire 4 can be lengthened and shortened.

In order to rotate the take-up pulley 6 better, as shown in fig. 2, a rocker arm 8 is provided on the take-up pulley 6, and the take-up pulley 6 can be rotated more quickly by rocking the rocker arm. In addition, the mounting frame 7 can be provided with a butterfly nut, and the butterfly nut can be loosened when the take-up pulley 6 needs to be rotated, so that the take-up pulley 6 is loosened at the end part of the butterfly nut, and the take-up pulley 6 can be rotated at the moment. When the take-up pulley 6 does not need to be rotated, the butterfly nut is screwed down, the end part of the butterfly nut props up the take-up pulley 6 tightly, and the take-up pulley 6 cannot rotate at the moment.

As shown in fig. 1, the abutting structure comprises an upper pressing assembly and a lower pressing assembly; go up to compress tightly the subassembly and compress tightly the subassembly down and lie in the same side of montant 1 to distribute from top to bottom.

The upper pressing component and the lower pressing component are identical in structure and size. Specifically, go up to compress tightly the subassembly and include connecting rod 2 and fixture block 3, the one end of connecting rod 2 is connected with montant 1, its other end then is connected with fixture block 3. Since the structure of the lower compressing assembly is the same as that of the upper compressing assembly, the structure of the lower compressing assembly will not be described in detail here.

Since the straight rod type lightning rod 10 is cylindrical, as shown in fig. 1, the arc-shaped clamping cavity is formed on the clamping surface of the clamping block 3, and the clamping block 3 can be better attached to the surface of the straight rod type lightning rod 10 by the arc-shaped clamping cavity.

During detection, the vertical rod 1 is held by hand, and the clamping blocks 3 on the upper pressing assembly and the lower pressing assembly are clamped on the surface of the straight rod type lightning rod 10, as shown in fig. 3. Because the structure and the size of the upper pressing component and the lower pressing component are completely the same, and the connecting rod 2 is vertical to the vertical rod 1, the vertical rod 1 is parallel to the straight rod type lightning rod 10 at the moment. The wire take-up wheel 6 is rotated to lengthen the suspension wire 4, so that the balancing weight 11 is lowered to the position of the scale rod 5, and the suspension wire 4 is always in a vertical state under the action of the gravity of the balancing weight 11. If the straight rod type lightning rod 10 is in a vertical state, the counterweight block 11 points to the zero scale position of the scale rod 5. If the straight rod type lightning rod 10 is inclined, the counterweight block 11 can point to the corresponding scale of the scale rod 5, as shown in fig. 3; because the distance H from the take-up pulley 6 to the scale rod 5 is obtained during the production of the device, the scale length L indicated by the counterweight block 11 can be directly read from the scale rod 5, and the inclination angle α of the straight rod type lightning rod 10 can be calculated according to a trigonometric function formula, as shown in fig. 4. Of course, the angle scale can be directly marked on the graduated rod 5, so that the inclination angle of the straight rod type lightning rod 10 can be read more directly. During detection, the device can be attached to different directions of the straight rod type lightning rod 10, and the straight rod type lightning rod 10 can be detected from different directions, so that the direction in which the straight rod type lightning rod 10 inclines can be known. After the detection is finished, the take-up pulley 6 is rotated, the suspension wire 4 is retracted, and finally the take-up pulley 6 is locked by a butterfly nut.

The diameter of the take-up pulley 6 can be set according to the situation, as long as the counterweight block 11, the suspension wire 4 and the vertical rod 1 are ensured not to influence each other when the suspension wire 4 is taken up and released. The weight block 11 may be formed in an inverted cone shape, and the tip of the lower portion thereof may be more accurately directed to a scale. When transferring balancing weight 11, some rocks can appear in suspension wire 4 inevitable, after the length of putting down is enough, only need hold up balancing weight 11 a little with the other hand, make balancing weight 11 stop rock can, it can not influence the normal use of device, relatively the conventional art, it can not bring the trouble for the measurement personnel yet. In addition, a clamp 9 can be arranged on the vertical rod 1, the clamp 9 is located at the upper end of the vertical rod 1, and is located on the same side of the vertical rod 1 as the scale rod 5, when the suspension wire 4 is retracted, the balancing weight 11 can be clamped into the clamp 9 for fixing, the balancing weight 11 is prevented from swinging during movement of the device, and the device is convenient to store. When in use, the lowered suspension wire 4 can pass through the bayonet of the clamp 9.

It should be noted that all features disclosed in this specification, or all steps of a method or process so disclosed, may be combined in any combination, except features and/or steps that are mutually exclusive.

In addition, the above embodiments are exemplary, and those skilled in the art can devise various solutions in light of the disclosure, which are all within the scope of the disclosure and fall within the scope of the invention. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
