Description

Tower line distance measuring device for power transmission line Technical Field The utility model relates to the technical field of power transmission line inspection workers, in particular to a tower line distance measuring device for a power transmission line. Background The tower line distance refers to a safe distance between a tower and a wire in a power transmission line, particularly a minimum distance which is required to be kept in a high-voltage environment to avoid discharge danger, a tower ruler is required to be used as a vertical scale when the tower line distance is measured, a height reference system is established through the scale, the tower ruler is closely attached to a tower part and vertically placed, a theodolite aims at the lowest point of the wire, and the scale difference delta H of the tower and the wire on the tower ruler is read to directly reflect the safe distance ‌ in the vertical direction. However, in the prior art, the tower ruler is generally made of aluminum alloy materials, has no insulativity, has potential safety hazards such as personal induction electric shock in the measurement process, is connected between each section of the tower ruler through a buckle, and is easy to loosen or slide when the buckle between sections of the tower ruler is not clamped in place during use, so that the height data is jumped during measurement, centimeter-level errors are generated, the loose sections can suddenly shrink, the instrument is damaged due to falling, and the safety ‌ of operators is endangered even because of dumping of the tower ruler. Disclosure of utility model The utility model aims to provide a tower line distance measuring device for a power transmission line, which aims to solve the problems in the background technology. The tower line distance measuring device for the power transmission line comprises a tower section and an anti-slip assembly, wherein the anti-slip assembly is arranged in the tower section and comprises anti-drop holes symmetrically arranged on two sides of the bottom end of the tower section, anti-drop pins are axially and slidably arranged in the anti-drop holes on two sides, and the anti-drop pins are fixedly connected to two ends of a clamp spring. Furthermore, the clamp spring is made of spring steel, and the clamp spring is of a V-shaped structure. Further, the tower section is internally provided with a fool-proof component, the fool-proof component comprises jacks arranged at the upper end and the lower end of the tower section, and bolts are axially and slidably arranged in the jacks. Further, the fool-proof assembly further comprises a sleeve sleeved outside the bolt, and the root of the sleeve is fixed with the inner wall of the tower section. Further, prevent slow-witted subassembly still includes the spring of cover locating the bolt root, and the bolt passes through spring and sleeve opening inner wall elastic connection. Furthermore, the fool-proof assembly further comprises a trigger rod radially inserted in the middle of the sleeve, and the step groove on the side surface of the trigger rod is in butt fit with the plane of the tail end of the bolt. Further, prevent slow-witted subassembly still includes the connecting rod of connecting in trigger lever top both sides, and the connecting rod is articulated mutually with jump ring "V" shape processing inner wall. Further, the multisection tower section piles up and sets up in the body of the tower inside, and tower section and body of the tower all adopt insulating stereoplasm ABS material to be provided with the scale mark along length direction equidistant on tower section and the body of the tower. Compared with the prior art, the utility model has the following beneficial effects: 1. When the telescopic tower is used, the tower sections are sequentially pulled out from the tower body, and when one section of the ruler body is pulled out, the clamp spring at the bottom end of the tower section pushes the anti-falling pin to extend under the action of elastic force, so that the anti-falling pin is clamped at the joint of the tower sections at the upper end and the lower end, and the risk of unexpected shrinkage of the ruler during high-altitude operation can be thoroughly avoided. 2. When the anti-drop locking device is used, when the V-shaped clamp spring expands and pushes the anti-drop pins to extend to two sides, the hinged connecting rods on the inner walls of the two sides of the clamp spring synchronously pull the trigger rod to descend, so that the pin extends out of the opening of the sleeve and is clamped into the jack arranged at the upper end of the next tower section through the abutting fit of the step groove on the side surface of the trigger rod and the plane of the tail end of the pin, the next tower section can be pulled out of the tower body only when the pin is inserted in place, and the operation checking step is reduced through the fool-proof structural des
