[0002] The tilting of high-voltage transmission line towers poses a major threat to the safe operation of the lines. In severe cases, it will cause tower collapse and line breakage, resulting in power supply interruption, posing a serious hidden danger to the power supply company's safe production and power supply guarantee.

[0003] At present, the commonly used methods for measuring the inclination of pole towers are: 1) Theodolite measurement. This measurement method is complicated, time-consuming, inefficient, and limited by the terrain conditions on site. Many high-voltage line pole towers are located in deep mountains and forests, and there are no roads to reach them. It is extremely inconvenient to carry a theodolite to the site for measurement; 2) Online monitoring device for the inclination of pole towers. Install a pole tower inclination monitoring device on the pole tower, and upload the pole tower inclination data to the monitoring center at regular intervals. The advantages of this solution are high efficiency and timeliness, and the disadvantages are high equipment investment costs, high operation and maintenance costs, and limited by the communication network, and it has not been widely promoted and used. Summary of the invention

[0004] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a tower tilt monitoring device, which has a simple structure, low cost, and easy installation, and the monitoring structure is simple and clear, which can effectively improve the work efficiency of the staff.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A pole tower inclination monitoring device comprises a fixed installation mechanism, a swing mechanism and a scale structure, wherein the scale structure is fixedly installed on the lower end surface of the fixed installation mechanism, the upper end of the swing mechanism is fixedly installed in the scale structure, the lower end of the swing mechanism is higher than the upper end surface of the scale structure, the scale structure comprises a fixed seat, a connecting plate and a scale plate, the fixed seat is fixedly installed on the lower end surface of the fixed installation mechanism, the upper end surface of the connecting plate is fixedly connected to the fixed seat, the lower end surface of the connecting plate is fixedly connected to the scale plate, the lower end position of the swing mechanism is higher than the upper end position of the scale plate, and the monitoring device indirectly reflects whether the pole tower is tilted by reading the position deviation of the swing mechanism corresponding to different scale structures twice, if there is a difference, the pole tower is tilted, if there is no difference, the pole tower is not tilted.

[0007] While adopting the above technical solutions, the present invention further adopts or combines the following technical solutions.

[0008] The swing mechanism comprises a hanging line head, a line sinker and a cycloid. The hanging line head is fixedly mounted on the lower end surface of the fixing seat, and two ends of the cycloid are respectively connected with the hanging line head and the line sinker.

Preferably, the thickness of the middle section is less than or equal to the thickness of the upper connecting plate, and the lower connecting plate is clamped by the lower end face of the upper section and the upper end face of the hanging wire head, thereby improving the connection strength between the connecting plate and the fixed seat.

[0021] The upper end surface of the hanging line head is provided with a screw hole, and the line pendant is in a cone shape.

[0022] In some preferred embodiments, the lower end surface of the hanging line head is also conical, the upper end of the cycloid is connected to the tip of the conical hanging line head, and the lower end of the cycloid is connected to the circular surface of the plumb line.

Through the setting of the light emitting device, the lower end of the plumb line is projected onto the scale disk, which facilitates the scale disk degree and improves the accuracy of the monitoring results.

[0024] The center of the spherical surface of the ruler disk coincides with the bottom of the hanging wire head.

[0025] The beneficial effects of the present invention are: (1) the monitoring device has a simple structure, low cost, easy installation, and can effectively monitor towers in various environments.

[0026] (2) By reading the position deviation of the swing mechanism twice on different scale structures, it can indirectly reflect whether the tower is tilted.
