Description

Technical Field

[0001] This utility model relates to the field of ceramic insulator technology, specifically to a suspended high-voltage ceramic insulator structure. Background Technology

[0002] In the field of high-voltage power transmission and transformation, insulator strings are used to connect overhead transmission lines and towers, providing insulation between them. As the voltage level of transmission lines gradually increases, the length of insulator strings also gradually increases. String types include conventional straight strings, tension strings, and V-shaped strings to prevent wind deflection of overhead lines. In the field of high-voltage power transmission and transformation, the most common insulator strings are usually straight strings, suspended at both ends of the iron frame of the transmission network.

[0003] Currently, high-voltage ceramic insulators installed under suspension are generally fixed to both sides of an iron frame using bolts at the top. Due to their high altitude and weight, it is extremely inconvenient for workers to suspend and install the high-voltage ceramic insulators on both sides of the iron frame. Multiple workers are required to work together to complete the installation. The workers are engaged in high-altitude work for extended periods, which is physically demanding and poses certain safety hazards.

[0004] Therefore, it is necessary to propose a suspended high-voltage ceramic insulator structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a suspended high-voltage ceramic insulator structure. Through the mutual cooperation between the internal parts of the connecting mechanism, it is easy to quickly connect and pre-fix the ceramic insulator body to the transmission frame. Through the mutual cooperation between the internal parts of the fixing mechanism, it is easy to complete the connection and locking fixation between the ceramic insulator body and the transmission frame. This solves the problem that in the prior art, it is extremely inconvenient for workers to suspend and install high-voltage ceramic insulators on both sides of the iron frame at high altitude. It requires multiple workers to cooperate to complete the suspension and installation of high-voltage ceramic insulators. Moreover, the workers are engaged in high-altitude work for a long time, which greatly consumes physical strength and poses certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended high-voltage ceramic insulator structure, including a power transmission frame, a connecting mechanism fixedly connected to one side of the power transmission frame and extending into the interior of the power transmission frame, and a fixing mechanism fixedly connected to the bottom end of the connecting mechanism and extending into the interior of the power transmission frame.

[0007] Preferably, the connecting mechanism includes a ceramic insulator body, an insulator blade sleeved on the outer wall of the ceramic insulator body, a fixing block connected and fixed at the top of the ceramic insulator body and extending into the interior of the transmission frame, and a fixing bolt threadedly connected to the top of the transmission frame and extending into the interior of the fixing block.

[0008] Preferably, the fixing mechanism includes a connecting column, which is located at the bottom end of the ceramic insulator body and extends into the interior of the ceramic insulator body. A traction ring is fixedly connected to the bottom end of the connecting column, and a threaded column is fixedly connected to the top end of the connecting column, extending through the ceramic insulator body to the interior of the fixing block. A retaining ball is provided at the top end of the threaded column and extends to the bottom end of the fixing bolt. Sliding columns are slidably connected to both sides of the ceramic insulator body, extending through the ceramic insulator body to the interior of the insulator blade and located on both sides of the outer wall of the connecting column. A limit plate is fixedly connected to the top end of the sliding column and slidably connected to the interior of the ceramic insulator body. A limit spring is fixedly connected to one side of the limit plate.

[0009] Preferably, a connecting groove matching the fixing block is provided on one side of the transmission frame, and threaded grooves matching the fixing bolts are provided on the top of both the fixing block and the transmission frame. A limiting ring matching the insulator blades is provided on the outer wall of the bottom end of the ceramic insulator body.

[0010] Preferably, the ceramic insulator body has an internal mating groove that matches the connecting post, the top of the ceramic insulator body has a threaded groove that matches the threaded post, and the bottom of the fixing bolt has a retaining groove that matches the retaining ball.

[0011] Preferably, the ceramic insulator body has a sliding groove inside that matches the sliding post, the ceramic insulator body has a limiting groove inside that matches the limiting plate, the insulator blade has multiple fixing grooves inside that match the sliding post, and the connecting post and threaded post are both made of insulating material.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. By matching the fixing block at the top of the ceramic insulator body with the connecting groove on the transmission frame, it is easy for workers to move the ceramic insulator body that needs to be suspended to one side of the transmission frame through the fixing block, and then move it into the inside of the connecting groove on the transmission frame to complete the docking connection between the fixing block and the connecting groove. This completes the docking between the ceramic insulator body and the transmission frame. Then, by rotating the fixing bolt, the fixing bolt is made to pass through the fixing block and the inside of the transmission frame, thus completing the pre-fixing of the connection between the ceramic insulator body and the transmission frame.

[0014] 2. By inserting the connecting post into the ceramic insulator body and then rotating the connecting post, the threaded post at the top rotates, causing the threaded post to connect and fix the connecting post to the ceramic insulator body through the threads. At the same time, the threaded post slides inside the ceramic insulator body, causing the retaining ball at the top to pass through into the fixing bolt, limiting and fixing the position of the fixing bolt. Simultaneously, the connecting post drives the traction ring at the bottom to connect and fix to the bottom of the ceramic insulator body, facilitating the traction and suspension operation of the ceramic insulator body on the transmission line. At the same time, the connecting post presses the sliding post inside the ceramic insulator body, causing the sliding post to drive the limiting plate to compress and move the limiting spring, moving the sliding post into the insulator blade, completing the connection and fixation of the insulator blade. This completes the installation and fixation of the ceramic insulator body on the transmission line, thus facilitating the suspension installation of the ceramic insulator body.

[0026] Refer to the instruction manual appendix Figure 1-6 The connecting mechanism 2 includes a ceramic insulator body 201, an insulator blade 202 sleeved on the outer wall of the ceramic insulator body 201, a fixing block 203 fixedly connected to the top of the ceramic insulator body 201 and extending into the interior of the transmission frame 1, and a fixing bolt 204 threadedly connected to the top of the transmission frame 1 and extending into the interior of the fixing block 203. Through the mutual cooperation between the internal parts of the connecting mechanism 2, the docking connection between the ceramic insulator body 201 and the transmission frame 1 can be completed.

[0027] Refer to the instruction manual appendix Figure 1-6 The fixing mechanism 3 includes a connecting column 301, which is located at the bottom end of the ceramic insulator body 201 and extends into the interior of the ceramic insulator body 201. A traction ring 302 is fixedly connected to the bottom end of the connecting column 301, and a threaded column 303 is fixedly connected to the top end of the connecting column 301 and extends into the interior of the ceramic insulator body 201 and the fixing block 203. A retaining ball 304 is provided at the top end of the threaded column 303 and extends into the bottom end of the fixing bolt 204. Sliding columns 305 are slidably connected to both sides of the ceramic insulator body 201 and extend into the interior of the insulator blade 202, located on both sides of the outer wall of the connecting column 301. A limiting plate 306 is fixedly connected to the top end of the sliding column 305 and slidably connected into the interior of the ceramic insulator body 201. A limiting spring 307 is fixedly connected to one side of the limiting plate 306. Through the mutual cooperation between the internal parts of the fixing mechanism 3, the connection and fixing between the ceramic insulator body 201 and the transmission frame 1 can be easily completed.

[0028] Refer to the instruction manual appendix Figure 1-6The transmission frame 1 has a connecting groove on one side that matches the fixing block 203. The top of both the fixing block 203 and the transmission frame 1 has a threaded groove that matches the fixing bolt 204. The outer wall of the bottom end of the ceramic insulator body 201 is provided with a limiting ring that matches the insulator blade 202. The threaded grooves that match the fixing bolt 204 on the top of both the fixing block 203 and the transmission frame 1 facilitate the fixing bolt 204 to pass through the fixing block 203 and the transmission frame 1, thus completing the connection between the fixing block 203 and the transmission frame 1.

[0029] Refer to the instruction manual appendix Figure 1-6 The ceramic insulator body 201 has a mating groove inside that matches the connecting post 301. The top of the ceramic insulator body 201 has a threaded groove that matches the threaded post 303. The bottom of the fixing bolt 204 has a slot that matches the retaining ball 304. The threaded groove at the top of the ceramic insulator body 201 that matches the threaded post 303 facilitates the connection and fixation of the connecting post 301 to the ceramic insulator body 201 through the threaded post 303.

[0030] Refer to the instruction manual appendix Figure 1-6 The ceramic insulator body 201 has a sliding groove inside that matches the sliding post 305. The ceramic insulator body 201 also has a limiting groove inside that matches the limiting plate 306. The insulator blade 202 has multiple fixing grooves inside that match the sliding post 305. The connecting post 301 and the threaded post 303 are both made of insulating material. The sliding groove inside the ceramic insulator body 201 that matches the sliding post 305 facilitates the sliding post 305 to slide inside the ceramic insulator body 201 and into the insulator blade 202.

[0031] The working principle of this practical application is as follows:

[0032] Refer to the instruction manual appendix Figure 1-6 By matching the fixing block 203 at the top of the ceramic insulator body 201 with the connecting groove on the transmission frame 1, it is convenient for the staff to move the ceramic insulator body 201, which needs to be suspended and installed, to one side of the transmission frame 1 through the fixing block 203, and move it into the inside of the connecting groove on the transmission frame 1 through the fixing block 203 to complete the docking connection between the fixing block 203 and the connecting groove, thus completing the docking between the ceramic insulator body 201 and the transmission frame 1. Then, by rotating the fixing bolt 204, the fixing bolt 204 is made to pass through the fixing block 203 and the inside of the transmission frame 1, thus completing the pre-fixing of the connection between the ceramic insulator body 201 and the transmission frame 1.

[0033] Refer to the instruction manual appendix Figure 1-6By inserting the connecting post 301 into the ceramic insulator body 201 and then rotating the connecting post 301, the rotation of the connecting post 301 drives the threaded post 303 at the top to rotate, so that the threaded post 303 drives the connecting post 301 to be connected and fixed to the ceramic insulator body 201 through the thread. At the same time, the threaded post 303 slides inside the ceramic insulator body 201, driving the retaining ball 304 at the top to pass through into the fixing bolt 204, limiting and fixing the position of the fixing bolt 204. Simultaneously, the connecting post 301 drives the traction ring 302 at the bottom to connect with the ceramic insulator. The bottom of the main body 201 is fixed, which facilitates the traction and suspension of the ceramic insulator main body 201 on the transmission line. At the same time, the connecting column 301 presses the sliding column 305 inside the ceramic insulator main body 201, so that the sliding column 305 drives the limiting plate 306 to compress the limiting spring 307 and move it. This moves the sliding column 305 into the insulator blade 202, completing the connection and fixation of the insulator blade 202. This completes the installation and fixation of the ceramic insulator main body 201 on the transmission frame 1, thus facilitating the suspension and installation of the ceramic insulator main body 201.
