[0002] UHV suspension porcelain insulators are an insulator used to support and suspend line conductors in UHV overhead transmission and distribution lines. UHV has the advantages of large capacity, long distance, and high efficiency. It can transmit electricity across regions, which is conducive to optimizing my country's power grid and power supply layout. With the large-scale centralized construction of UHV projects, the demand for UHV suspension porcelain insulators is increasing.

[0003] At present, the connections between UHV suspension porcelain insulators have not been protected and reinforced. When operating at high altitudes, they are subject to strong winds, which can easily cause the connection ends of the UHV suspension porcelain insulators to tilt and be damaged. In addition, the connection ends of the UHV suspension porcelain insulators will shake due to the force, causing wear on the connection ends, thereby increasing the damage rate of the UHV suspension porcelain insulators and affecting the safety of the use of UHV overhead transmission and distribution lines.

[0004] Therefore, we proposed a protective and reinforced UHV suspension porcelain insulator to solve the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The protective reinforced UHV suspension porcelain insulator uses a limiting rod to sequentially penetrate the first through hole and the second through hole to limit the adjacent spliced ​​porcelain insulators, and uses a threaded rod and a nut threaded on the threaded rod to lock the limiting rod, thereby locking the spliced ​​porcelain insulators. In addition, the position of the limiting rod can be further locked by using a connecting plate and a reinforcement rod penetrated in the reinforcement groove, so that the limiting rod that locks the porcelain insulator will not shake and wear when subjected to wind force, thereby reducing the damage rate at the connection end of the porcelain insulator;

[0017] (2) The protective and reinforced UHV suspension porcelain insulator utilizes inclined and retractable auxiliary rods and main rods to reinforce and support the spliced ​​porcelain insulators. At the same time, the connecting ends between the porcelain insulators are protected and reinforced by connecting plates, reinforcement rods, threaded rods, and limit rods. When subjected to strong winds, the connection ends of the porcelain insulators are kept stable to prevent them from becoming loose or damaged due to stress. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6 The utility model provides the following technical solution: a protective reinforced UHV suspension porcelain insulator, comprising a porcelain insulator shed 1, an iron cap 2 being mounted on the upper end of the porcelain insulator shed 1, a steel leg 3 being connected to the lower side of the porcelain insulator shed 1, a second through hole 5 being formed at the lower end of the steel leg 3, a first through hole 4 being formed on the iron cap 2, and a limit rod 6 passing through the interiors of the first through hole 4 and the second through hole 5;

[0027] The front and rear ends of the limiting rod 6 are provided with locking holes 7, the interior of the locking hole 7 is penetrated by a threaded rod 8, the outer side of the lower portion of the threaded rod 8 is threadedly connected to a nut 10, the upper end of the threaded rod 8 is installed with a connecting plate 9, and the lower side of the connecting plate 9 away from the end of the threaded rod 8 is connected to a reinforcing rod 11;

[0028] Furthermore, the threaded rod 8 and the reinforcement rod 11 are connected by a connecting plate 9. The connecting plate 9 is an arc-shaped structure, which can be driven to move so that the threaded rod 8 corresponds to the position of the locking hole 7, and the reinforcement rod 11 corresponds to the position of the reinforcement groove 12, thereby locking the connecting plate 9, the limit rod 6 and the iron cap 2 to each other;

[0029] Furthermore, the connecting plates 9 are distributed at equal angles with respect to the longitudinal centerline of the iron cap 2, and two sets of auxiliary rods 13 are hinged on the outer side of the connecting plates 9, which can symmetrically lock the connecting plates 9, the limiting rods 6 and the iron cap 2 to each other;

[0030] Furthermore, the threaded rod 8 and the limiting rod 6 are engaged with each other, and the interior of the locking hole 7 through which the threaded rod 8 passes is smooth, so that the threaded rod 8 passes through the limiting rod 6 smoothly, and the threaded rod 8 and the limiting rod 6 are locked using the nut 10;

[0031] Reinforcement grooves 12 are provided inside the left and right ends of the iron cap 2;

[0032] Furthermore, the position of the reinforcement rod 11 corresponds to the position of the reinforcement groove 12, and the reinforcement rod 11 and the reinforcement groove 12 are engaged with each other. When the porcelain insulator is subjected to force, the connecting plate 9 is stuck on the iron cap 2, thereby reinforcing the connection end of the porcelain insulator;

[0033] The outer side of the connecting plate 9 is hinged with a secondary rod 13, and the outer side of the secondary rod 13 is sleeved with a main rod 14. A spring 15 is connected between the secondary rod 13 and the main rod 14. The upper end of the main rod 14 is hinged to the porcelain insulator shed 1;

[0034] Furthermore, the auxiliary rod 13 forms an elastic structure with the main rod 14 through the spring 15. The main rod 14 has four groups of equal angles distributed about the longitudinal center line of the porcelain insulator shed 1, so that the auxiliary rod 13 and the main rod 14 can be flexibly extended and retracted, so that the position of the connecting plate 9 can be flexibly moved to avoid the connecting plate 9 being stuck.

[0035] Specifically, the steel foot 3 installed on the porcelain insulator shed 1 is inserted into the iron cap 2 installed on the porcelain insulator shed 1 at the adjacent position, so that the positions of the first through hole 4 and the second through hole 5 are aligned, and the limiting rod 6 is passed through the first through hole 4 and the second through hole 5 to limit the iron cap 2 and the steel foot 3, thereby limiting the two adjacent insulators, and then the threaded rod 8 installed at the lower end of the connecting plate 9 is aligned with the locking hole 7 opened at the end of the limiting rod 6. At this time, when the position of the connecting plate 9 is adjusted, the auxiliary rod 13 is forced to slide in the main rod 14, and ... The rod 13 squeezes and stores force on the spring 15. At the same time, the lower end of the auxiliary rod 13 rotates on the hinged connecting plate 9, and the upper end of the main rod 14 rotates on the hinged porcelain insulator shed 1, so that the threaded rod 8 is smoothly aligned with the locking hole 7, and the threaded rod 8 is passed through the locking hole 7. The nut 10 is threadedly connected to the threaded rod 8, and the threaded rod 8 and the limit rod 6 are locked, so that the limit rod 6 firmly splices and locks the porcelain insulator. The main rod 14 and the auxiliary rod 13 are locked with bolts to reinforce and support the spliced ​​porcelain insulator.

[0036] When the connecting plate 9 drives the threaded rod 8 to move downward, the reinforcement rod 11 can be controlled to move downward so that the reinforcement rod 11 is inserted into the reinforcement groove 12 opened in the iron cap 2, thereby stabilizing the relative position between the connecting plate 9 and the iron cap 2. The threaded rod 8, connecting plate 9, auxiliary rod 13, main rod 14 and other structures are used to protect and reinforce the connection ends between the porcelain insulators. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
