Description

Technical Field

[0001] This utility model relates to the field of hollow composite insulator technology, specifically a hollow composite insulator that is easy to install. Background Technology

[0002] Hollow composite insulators are a special type of insulation control, mainly composed of an insulating core rod inner cylinder, end flanges, and silicone rubber sheds. They are widely used in power systems such as overhead transmission lines. They are installed by connecting the end flange at the bottom of the insulating core rod inner cylinder to a support frame, and can support the conductor during use.

[0003] In existing hollow composite insulators, the insulators are installed solely through the bottom flange during conductor support, making it difficult to guarantee installation strength. Under special weather conditions, such as strong winds after icing, high-voltage conductors may gallop. When the conductors gallop, they generate large-scale swinging and twisting, applying huge dynamic tensile and torque forces to the hollow composite insulators. This may cause structural deformation of the insulators, thereby reducing their service life. To address the shortcomings of existing technology, we propose an easy-to-install hollow composite insulator to solve the above problems. Utility Model Content

While facilitating the installation of the hollow composite insulator body and support frame, the support plate increases the contact area between the bottom of the hollow composite insulator body and the support frame. Increasing the contact area allows for more uniform force distribution and enhances connection stability.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a hollow composite insulator that is easy to install.

[0025] According to the appendix Figure 1-6 As shown, the device includes a hollow composite insulator body 1 and a support frame 2. The hollow composite insulator body 1 is fixedly installed on the top of the support frame 2 via an installation assembly 3. The hollow composite insulator body 1 is composed of a hollow core rod 101 and silicone rubber sheds 102. Multiple sets of silicone rubber sheds 102 are evenly spaced and fixedly sleeved on the outer peripheral wall of the hollow core rod 101. A support plate 4 is provided at the bottom of the hollow composite insulator body 1, which increases the contact area between the hollow composite insulator body 1 and the support frame 2. A limit frame 6 is provided at the top of the support frame 2, and the support plate 4 is inserted into the limit frame 6. Before installing the hollow composite insulator body 1 and the support frame 2, the support plate 4 at the bottom of the hollow composite insulator body 1 is first picked up, so that the end threaded cylinder 301 is aligned with the installation threaded post 302, and the support plate 4 is aligned with the limit frame 6. By rotating the end threaded cylinder 301, the end threaded cylinder 301 is sleeved on the outer peripheral wall of the installation threaded post 302, thus realizing the preliminary installation of the hollow composite insulator body 1 and the support frame 2.

[0026] Multiple sets of locking elements 7 are provided inside the four sides of the limiting frame 6 and the support plate 4. The locking elements 7 connect to the support frame 2. The outer peripheral walls of the support plate 4 and the limiting frame 6 are symmetrically provided with a first mounting plate 701 and a second mounting plate 702. The bottom of the limiting frame 6 is provided with a first driving component 8 and a second driving component 9. The first driving component 8 is connected to the two symmetrical sets of first mounting plates 701, and the second driving component 9 is connected to the two symmetrical sets of second mounting plates 702. After the support plate 4 and the limiting frame 6 are installed and connected, the symmetrically provided first mounting plates 701 and second mounting plates 702 can slide closer to each other through the cooperation of the two driving components. This allows the locking elements 7 on the four sides of the limiting frame 6 to be inserted into the inside of the limiting frame 6 and the support plate 4, thereby locking the installed support plate 4 and the limiting frame 6 and fixing the installed support plate 4 to the support frame 2.

[0027] The first drive assembly 8 drives the first mounting plates 701 on both sides to slide closer to each other, and the second drive assembly 9 drives the second mounting plates 702 on both sides to slide closer to each other, so that multiple sets of locking pieces 7 are inserted into the limiting frame 6 and the support plate 4. The top of the support frame 2 is fixedly connected to the mounting base plate 5, the limiting frame 6 is fixedly connected to the top of the mounting base plate 5, and the top of the mounting base plate 5 is fixedly connected to the protective frame 501. The first mounting plate 701 and the second mounting plate 702 are both slidably connected inside the protective frame 501. During use, the support plate 4 can increase the contact area between the bottom of the hollow composite insulator body 1 and the support frame 2. Increasing the contact area between the hollow composite insulator body 1 and the support frame 2 can make the force distribution more uniform. When the core rod is subjected to external force, the support plate 4 can better transmit the force to the support frame 2. The support plate 4 can reduce the situation of excessive local pressure on the hollow composite insulator body 1, and avoid deformation or damage to the hollow composite insulator body 1 and the support frame 2 due to local force concentration. In this way, the strength of the hollow composite insulator body 1 after installation can be improved and the service life can be increased.

[0028] The mounting assembly 3 includes an end threaded cylinder 301 and a mounting threaded post 302. The end threaded cylinder 301 is fixedly installed at the bottom of the hollow rod 101, and the mounting threaded post 302 is fixedly installed inside the limiting frame 6. The support plate 4 is fitted onto the outer peripheral wall of the end threaded cylinder 301, and the end threaded cylinder 301 is threaded onto the outer peripheral wall of the mounting threaded post 302. It should be noted that when the hollow composite insulator body 1 and the support frame 2 are installed using the mounting assembly 3, the support plate 4 is rotated and fitted onto the outer peripheral wall of the hollow rod 101, so that the limited support plate 4 does not affect the installation of the hollow rod 101 and the support frame 2.

[0029] The first drive assembly 8 includes a first rotating member 801, a first bidirectional screw 802, and a first drive member 803. The first bidirectional screw 802 is rotatably connected inside the mounting base plate 5. The first drive member 803 is slidably sleeved on the outer peripheral walls on both sides of the first bidirectional screw 802. The top of the first drive member 803 is fixedly connected to the first mounting plate 701. The first rotating member 801 is mounted on the outer wall of the mounting base plate 5 and is fixedly connected to the end of the first bidirectional screw 802.

[0030] The second drive assembly 9 includes a second rotating member 901, a second bidirectional screw 902, and a second drive member 903. The second bidirectional screw 902 is rotatably connected inside the mounting base plate 5. The second drive member 903 is slidably sleeved on the outer peripheral walls on both sides of the second bidirectional screw 902. The top of the second drive member 903 is fixedly connected to the second mounting plate 702. The second rotating member 901 is mounted on the outer wall of the mounting base plate 5 and is fixedly connected to the end of the second bidirectional screw 902.
