[0002] Transmission towers are an indispensable component in the power transmission process. Their main function is to support overhead conductors, lightning conductors and other accessories, so that the conductors maintain a specified safe distance between each other, between the conductors and the ground or crossing objects.

[0003] Loosening of nuts on transmission towers is a serious problem that requires close attention in power transmission systems. The effects of wind and other natural forces can produce alternating lateral loads on transmission towers. This dynamic load can cause the bolt preload to decrease, leading to loosening. However, this relatively minor loosening is often difficult to detect. Therefore, a new type of nut loosening detection device is needed to solve the above problem. Summary of the Invention

[0027] like Figures 1 to 4 As shown, an embodiment of the present invention provides a nut loosening detection device, including a transmission tower body 1 with a hexagonal bolt 2 threaded on the surface. During normal construction, workers will sleeve the hexagonal nut 3 on the surface of the hexagonal bolt 2. The surface of the hexagonal nut 3 of the device is fixedly sleeved with an identification ring 4, and at the same time, a bubble level 5 is provided on one side of the hexagonal nut 3. The user can also install the bubble level 5 on the surface of the identification ring 4 through the installation mechanism 6 and control the bubble level 5 to rotate around the center of the identification ring 4. In this way, when the user screws on the hexagonal nut 3, the bubble of the bubble level 5 can be adjusted to a horizontal position, and a mark can be engraved on the surface of the identification ring 4 at the position where the bubble level 5 points. In the subsequent use process, it is necessary to detect the hexagonal nut 3. To check whether the angle nut 3 is loose, the user adjusts the bubble in the center of the bubble level 5 to the center position again. At this time, if the previous notch is facing the bubble level 5, it means that the hexagonal nut 3 is not loose. If it is skewed, it means that it is loose. The main components of the installation mechanism 6 are: an adjusting ring 602, and an adjusting groove 601 is provided on the surface of the identification ring 4, and the adjusting ring 602 is rotatably sleeved on the inner wall of the adjusting groove 601. When in use, the user installs the bubble level 5 on one end of the first connecting rod 603 fixedly installed on the surface of the adjusting ring 602 through the connecting mechanism 7, and can rotate the first connecting rod 603 to drive the adjusting ring 602 to rotate on the inner wall of the adjusting groove 601, thereby further realizing the adjustment of the position of the bubble level 5.

[0028] By providing an identification ring 4 fixedly sleeved on the surface of the hexagonal nut 3 and a bubble level 5 provided on one side of the hexagonal nut 3, the user can first install the bubble level 5 on the surface of the identification ring 4 through the installation mechanism 6 when using it later, and then control the bubble level 5 to rotate around the center of the identification ring 4, so that when the bubble in the center of the bubble level 5 is centered, a scratch aligned with the bubble level 5 is scraped on the surface of the identification ring 4 with a tool. After a period of time, the bubble of the bubble level 5 is adjusted to the center position again. By comparing the last scratch and the direction of the bubble level 5 on the surface of the identification ring 4 this time, the looseness of the nut can be judged. This arrangement allows the user to detect the looseness of the nut, which fully reflects the practicality of the device.

[0029] like Figures 1 to 4 As shown, the connecting mechanism 7 includes a connecting bolt 702, and the surface of the bubble level 5 is fixedly sleeved with a second connecting rod 701. When in use, the user slides one end of the second connecting rod 701 into one end of the first connecting rod 603, and then threadably inserts the connecting bolt 702 into the surface of the first connecting rod 603 and then into the surface of the second connecting rod 701. This can achieve the limitation of one end of the second connecting rod 701 on the inner wall of the first connecting rod 603, thereby realizing the installation of the bubble level 5.

[0030] like Figures 1 to 4 As shown, an L-shaped plate 8 is fixedly installed on the surface of the first connecting rod 603. When the first connecting rod 603 rotates with the center of the identification ring 4 as the center, the L-shaped plate 8 also rotates synchronously, and the direction of the L-shaped plate 8 is the center of the identification ring 4. Therefore, the user inserts the cutting tool into the through groove 9 opened on the surface of the L-shaped plate 8 and cuts the surface of the identification ring 4, so that more precise cutting can be achieved. A thin sheet 10 is fixedly installed on the inner wall of the through groove 9. After the device is used, the thin sheet 10 will be cut, thereby avoiding multiple uses and affecting the use effect. Rubber blocks 11 for moving the second connecting rod 701 are fixedly installed on both sides of the second connecting rod 701.

[0031] The working principle of the present utility model is as follows: after the user drives the hexagonal bolt 2 into the surface of the transmission tower body 1, the user installs the bubble level 5 on the surface of the identification ring 4 through the installation mechanism 6 and controls the bubble level 5 to rotate around the center of the circle of the identification ring 4. After the hexagonal bolt 2 is installed, the surface of the identification ring 4 can be marked. After a period of use, the bubble level 5 can be controlled to move to the previous position again and compare it with the mark on the surface of the offset identification ring 4, so as to determine whether the hexagonal nut 3 is loose.

[0032] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
