[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and technical solutions, and the implementation methods of the present invention will be described in detail through preferred embodiments, but the implementation methods of the present invention are not limited thereto.

[0026] In view of the fact that the existing transmission line fittings measurement requires manual handheld tape measurement, which is time-consuming, labor-intensive, inefficient, and the measurement is restricted by the weather environment, the embodiments of the present invention refer to Figure 1 As shown, a device for measuring the installation distance of power transmission line hardware is provided, comprising: a tape measure, and a sleeve for passing the tape measure strip; both ends of the sleeve are provided with a plugging cover, and the plugging cover is provided with an opening, and the end of the tape measure strip passes through the plugging cover opening at one end of the sleeve and extends out of the plugging cover opening at the other end of the sleeve to the position of the hardware to be measured.

[0027] The transmission line sections within the technical transformation project need to measure the distance between the hardware during acceptance. In the process of accepting and measuring the hardware gap, conductor discharge spacing, hardware installation, etc., it is necessary to use a tape measure for manual measurement. In the case of excessive extension of the tape measure or wind, the pulled-out part of the tape measure will swing and fall off, and the measurement work cannot be carried out normally. For example, when the staff used a tape measure to measure the above problems of the 110kVⅠ and Ⅱ Cihe lines when accepting the conductor anti-vibration hammer, jumper distance, and jumper to the iron tower, the tape measure would swing and fall off in the case of wind, affecting the acceptance progress. In the embodiment of the present invention, the tape measure bar is passed through the casing plug cover and extended out of the casing to ensure the ductility of the tape measure bar and the accuracy of data measurement. During the measurement process, the operator only needs to hold the casing to complete it, effectively avoiding the safety hazards of stepping on multiple positions in high-altitude measurement, and solving the time-consuming and labor-intensive manual tape measurement, and being affected by weather and environment. The situation can improve the accuracy of the overhead line hardware spacing measurement and improve the measurement efficiency.

[0028] As a transmission line hardware installation distance measuring device in an embodiment of the present invention, further, the sleeve includes sleeve 1 and sleeve 2, one end of the sleeve 1 and sleeve 2 are hinged by a connector, and the other end of the sleeve 1 and sleeve 2 are used to set a plug. By hingedly connecting sleeve 1 and sleeve 2 in one body, the distance measurement of the device to be tested at multiple angles, such as horizontal or vertical, is met, and the practicality is better.

[0029] As the transmission line fitting installation distance measuring device in the embodiment of the present invention, further, an observation port for reading the tape measure data is opened on the upper part of one end of the sleeve, so as to facilitate the quick and real-time reading of the measurement data.

[0030] As a transmission line fittings installation distance measuring device in an embodiment of the present invention, further, the connecting piece includes horizontal connecting plates arranged on both sides of the first end of the sleeve, and vertical connecting plates arranged on both sides of the second end of the sleeve, the horizontal connecting plate and the vertical connecting plate on the same side are hinged by a rotating shaft, the structure is simple and compact, and the fixation is stable and reliable.

[0031] As the transmission line fittings installation distance measuring device in the embodiment of the present invention, further, fixing pins are arranged between the horizontal connecting plates on both sides, so that the connection is firm.

[0032] As the transmission line fitting installation distance measuring device in the embodiment of the present invention, further, two mutually parallel fixing pins for adjusting the horizontal angle between sleeve 1 and sleeve 2 are arranged between the horizontal connecting plates on both sides. By adjusting the hinge position between the vertical connecting plate and the two fixing pins, the 90° vertical angle measurement and horizontal angle measurement of the fitting can be met, and the use effect is better.

[0033] As a transmission line fitting installation distance measuring device in an embodiment of the present invention, further, the tape measure strip passes through a gap between a fixing pin and a bottom inner wall of a sleeve, further ensuring the ductility of the strip in the sleeve, and effectively avoiding reading errors caused by its reversal, etc.

[0034] As a transmission line fitting installation distance measuring device in an embodiment of the present invention, further, the connecting piece also includes an oblique support plate hinged to the horizontal connecting plate and the vertical connecting plate on the same side, respectively. The three form a right-angled triangle structure for vertically measuring the distance of the fittings to be measured or the same horizontal line structure for horizontally measuring the distance of the fittings to be measured, which can meet the 90° vertical angle measurement and horizontal angle measurement of the fittings, has a better use effect, and ensures stability during the measurement process.

[0035] As a transmission line fitting installation distance measuring device in an embodiment of the present invention, further, the sleeve adopts a galvanized steel sleeve, which is not easy to deform during carrying and use, and the price is relatively economical; or it is a stainless steel sleeve, which has a bright surface and is not easy to bend and deform; or it is a plastic sleeve, which solves the problems of heavy weight and inconvenience of use of galvanized pipes, and solves the problems of high cost, high price, thin pipe wall and easy harm to human body of stainless steel pipes. The strength and weight are both suitable for the measurement of the spacing between fittings in the transmission line.

[0036] In the traditional acceptance of the distance between the hardware fittings of the transmission line, the acceptance personnel step on the insulator to the appropriate position and use a tape measure to measure the distance between the hardware fittings; this method is easy to damage the insulator shed and reduce the insulation performance. During the acceptance process, if the tape measure is extended too long or there is wind, the part where the tape measure is pulled out is easy to swing and fall off, causing the acceptance progress to be too slow. Further, the embodiment of the present invention also provides a method for measuring the installation distance of hardware fittings for a transmission line, which includes the following contents: according to the operating status of the transmission line, determine the technical transformation transmission line section; use the above-mentioned transmission line hardware installation distance measurement device to measure the hardware gap and the conductor discharge distance in the technical transformation transmission line section, connect or hook the end of the tape measure bar to the hardware to be measured, and the operator holds the casing to read the corresponding position data of the ruler bar, that is, obtain the required measurement hardware distance. Place the tape measure inside the casing for measurement. Since the tape measure is placed inside the material, the damage to the insulator shed and the work intensity of the acceptance personnel are reduced, the acceptance quality and progress are improved, and the tape measure is prevented from swinging and falling off when the tape measure is extended too long or there is wind, and the measurement work cannot be carried out normally.

[0037] In the embodiment of the present invention, the length of the bushing should not be too long. For example, it is used on 8 high-voltage transmission lines such as the 110kV Fanmi Line, the 10kV I and II Cihe Lines. According to actual needs, a plastic pipe with a length of 1.2m and a diameter of 3.5cm with a plugging cover is selected, and a horizontal line not exceeding 2.5cm is cut in the middle of the plugging cover so that the ruler can pass through the plugging covers on both sides, so as to prevent the tape measure from extending too long or swinging too much in the wind, thereby playing the role of fixing the tape measure and measuring the turning angle; the two bushings are foldably hinged together through a connecting piece to prevent the insulator shed from being damaged when the acceptance personnel go offline, and the spacing is measured without damaging the insulator, thereby achieving the expected effect and avoiding the need to step on the insulator during normal measurement; the problem of measuring the hardware is effectively solved, and the acceptance time is reduced. The measurement usually takes 2h when accepting this section. The existing measuring instrument in the present invention can achieve the measurement of equal spacing of hardware in 1h, and the efficiency is greatly improved, which can ensure the safe operation of the line. It can effectively solve practical problems that arise in work and achieve the expected results; improve the safe and reliable operation of the power grid, reduce the acceptance progress, and enhance the corporate image of safe power supply of power grid enterprises. It has good practicality and market value.
