DETAILED DESCRIPTION

[0026] ​​​The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The present application will be further described below with reference to specific implementation manners. The drawings are only used for exemplary description, and represent only schematic diagrams, not physical diagrams, and should not be understood as a limitation on the present patent; in order to better illustrate the embodiments of the present application, some components in the drawings will be omitted, enlarged or reduced, and the size of the actual product is not represented; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings can be omitted.

[0027] As shown in Figure 1 A seat type lightning arrester connecting base transition disc includes an annular track 1, a support frame 2 and a plurality of adjusting support rods, the annular track 1 is provided with a track groove 5, the support frame 2 is installed in the inner ring of the annular track 1, and the two opposite sides of the support frame 2 are respectively provided with corresponding upper positioning areas 6 and lower positioning areas 7; the adjusting support rods include first support rods 3 and second support rods 4, one end of the first support rod 3 is rotationally arranged in the upper positioning area 6, one end of the second support rod 4 is rotationally arranged in the lower positioning area 7, the other end of the first support rod 3 and the other end of the second support rod 4 are respectively slidably installed in the track groove 5 of the annular track 1 through sliding positioning assemblies, the first support rod 3 is provided with a first adjusting hole 8, and the second support rod 4 is provided with a second adjusting hole 9.

[0028] It should be noted that in the embodiment, the support frame 2 is preferably installed in the inner ring of the annular track 1, that is, the support frame 2 is inscribed in the annular track 1, which is used to improve the structural strength of the annular track 1 on the one hand and to support the adjusting support rods on the other hand, facilitating the installation of the adjusting support rods, and at the same time, in order to adapt to the installation of the adjusting support rods on both sides, the upper positioning areas 6 and the lower positioning areas 7 are respectively arranged on the two sides of the support frame 2, and the upper positioning areas 6 and the lower positioning areas 7 form the rotation centers of the first support rods 3 and the second support rods 4 respectively;

[0029] In the embodiment, the annular track 1 is provided with the track groove 5, and the sliding positioning assemblies can realize flexible sliding of the adjusting support rods, wherein the sliding positioning assemblies can be positioning bolts 15 and nuts, that is, the positioning bolts 15 are inserted into the track groove 5 through the adjusting support rods, and then the nuts are used to lock the set positions of the adjusting support rods, so as to realize flexible adjustment of the positions of the adjusting support rods;

[0030] In the embodiment, the adjusting support rods are divided into the first support rods 3 and the second support rods 4, wherein the first support rods 3 and the second support rods 4 are respectively installed on the opposite two sides of the support frame 2, as Figures 5-6As shown, the first support rod 3 is used to connect with the arrester base 19, and the second support rod 4 is used to connect with the support platform 20 of the power transmission line. When installing the adjusting support, the number of the first support rod 3 and the second support rod 4 can be selected according to the actual installation condition. In the embodiment, four first support rods 3 and four second support rods 4 are preferably used. One end of each first support rod 3 is rotatably installed in the upper positioning area 6 of the support frame 2 through a rotating shaft, and the other end of each first support rod 3 is installed in the track groove 5 of the annular track 1 through a sliding positioning assembly. The four first support rods 3 can respectively rotate around the respective rotating shaft along the annular track 1 flexibly and do not affect each other, so as to flexibly adjust the position of each first support rod 3. The installation and action principle of the second support rod 4 is the same as that of the first support rod 3, except that the first support rod 3 rotates at the upper end surface of the support frame 2, and the second support rod 4 rotates at the lower end surface of the support frame 2. The first support rod 3 and the second support rod 4 can be independently adjusted in position and do not affect each other.

[0031] The first adjusting hole 8 on the first support rod 3 and the second adjusting hole 9 on the second support rod 4 are respectively used to install the connecting bolt 17. For example, when connecting with the arrester base 19, the connecting bolt 17 is inserted into the installation hole on the arrester base 19 and then inserted into the first adjusting hole 8, so as to connect the arrester with the first support rod 3. In order to adapt to arrester bases 19 of different specifications, first, the first support rod 3 can slide along the annular track 1 to adjust the corresponding position. Second, the connecting bolt 17 can be adjusted in position in the first adjusting hole 8, so as to flexibly meet the installation of the arrester bases 19 of various design specifications and opening layouts. The application of the second support rod 4 is the same. The connecting bolt 17 is inserted into the installation hole of the support platform 20 of the power transmission cable and then inserted into the second adjusting hole 9, so as to connect the support platform 20 with the second support rod 4. Through the flexible rotation of the second support rod 4 and the opening of the second adjusting hole 9, the device can adapt to various installation holes of different positions opened on the original support platform 20, so as to directly complete the installation of the arrester without the need to additionally replace the base or reopen the hole on the support platform 20.

[0032] Compared with the prior art, the seat type arrester connecting base transition disc in the embodiment can meet the connection and installation with arresters of different specifications by adjusting the position of the first support rod 3 and cooperating with the first adjusting hole 8, without the need to additionally replace the base or reopen the hole. At the same time, the position of the second support rod 4 can be adjusted and the second adjusting hole 9 can be used in cooperation, so as to meet the connection and installation with the support platform 20 on the original power transmission line, without being limited by the layout of the arrester installation hole opened on the original support platform 20, thereby flexibly and stably installing arresters of different specifications on the support platform 20 of the power transmission line. The device not only can widely adjust the position of the first support rod 3 and the second support rod 4, but also has stronger applicability to the arrester and the support platform 20, without the need to reopen the hole, thereby reducing the operation and maintenance cost of the circuit and improving the work efficiency.

[0033] Further, as shown in Figure 4 order to improve the structural support of the ring track 1 while reducing the weight of the device, the support frame 2 in this embodiment is designed as a cross-shaped structure, and each end of the cross-shaped structure is inscribed in the ring track 1. In order to facilitate the installation of the first support rod 3 and the second support rod 4, the upper positioning area 6 and the lower positioning area 7 in this embodiment are designed to be located at the center of the support frame 2, i.e., at the center of the cross-shaped structure, which is equivalent to the center of the ring track 1, facilitating the adjustment of the rotation angle of the first support rod 3 and the second support rod 4. At this time, the first support rod 3 and the second support rod 4 have the same length, which is convenient for processing.

[0034] Further, as shown in Figure 4 order to improve the structural strength of the ring track 1 and the support frame 2 and better support the lightning arrester, the end of the support frame 2 connected to the ring track 1 in this embodiment is provided with a support seat 10. On the one hand, the support seat 10 can improve the connection strength between the support frame 2 and the ring track 1 and improve the structural stability. On the other hand, the support seat 10 can share the pressure of the lightning arrester and prevent the lightning arrester from bending and breaking the adjustment support rod.

[0035] Further, as shown in Figures 1-4 order to protect the adjustment support rod and prevent the lightning arrester from breaking the adjustment support rod and improve the service life of the device, the support seat 10 in this embodiment includes an upper support block 110 and a lower support block 120 installed on both sides of the support frame 2, respectively. The height of the upper support block 110 is slightly greater than the distance between the first support rod 3 and the support frame 2, and the height of the lower support block 120 is slightly greater than the distance between the second support rod 4 and the support frame 2.

[0036] It should be noted that the height of the upper support block 110 is designed to be slightly greater than the distance between the first support rod 3 and the support frame 2, and the height of the lower support block 120 is designed to be slightly greater than the distance between the second support rod 4 and the support frame 2. When the lightning arrester is installed, the lightning arrester can be supported on the support seat 10, thereby avoiding the lightning arrester directly pressing on the adjustment support rod, making it difficult to rotate the position of the adjustment support rod, and easily breaking the adjustment support rod;

[0037] And when the height of the support seat 10 is greater than the distance between the adjustment support rod and the support frame 2, an installation gap can be formed between the lightning arrester base 19 and the ring track 1, which can meet the requirements of disassembling and installing the connecting bolt 17 and the positioning bolt 15. In this embodiment, the installation gap is preferably designed to be 4 cm high.

[0038] Further, as shown in Figure 4As shown, in order to improve the structural strength of the support base 10, while not affecting the position adjustment of the adjusting support rod, the upper support block 110 and the lower support block 120 in the embodiment are designed as T-shaped structures, wherein the small end of the T-shaped structure faces the center of the support frame 2, the large end of the T-shaped structure faces the annular track 1, and a circular chamfer is designed at the connection transition part between the large end and the small end of the T-shaped structure.

[0039] Further, as shown in the drawings, Figures 1-6 As shown, in order to adjust the distance between the adjusting support rod and the support frame 2, facilitate the installation and removal of the connecting bolt 17 and the positioning bolt 15, in the embodiment, an upper pad 11 is arranged in the upper positioning area 6, and a lower pad 12 is arranged in the lower positioning area 7, the first support rod 3 is rotatably connected with the upper pad 11, and the second support rod 4 is rotatably connected with the lower pad 12.

[0040] It should be noted that in the embodiment, the first support rod 3 and the upper pad 11 are rotatably connected through the first rotating shaft 13, the second support rod 4 and the lower pad 12 are rotatably connected through the second rotating shaft 14, and the upper pad 11 and the lower pad 12 can be fixedly connected with the support frame 2. Of course, in order to facilitate maintenance and replacement and adjust the distance between the adjusting support frame and the support frame 2, they can also be designed as detachable connections. The height at which the upper pad 11 lifts the first support rod 3, i.e. the distance between the first support rod 3 and the support frame 2, is less than the height of the upper support block 110, and the distance between the second support rod 4 and the support frame 2 lifted by the lower pad 12 is less than the height of the lower support block 120. On the one hand, it avoids the lightning arrester directly abutting against the first support rod 3, causing the first support rod 3 to be bent and broken, and on the other hand, it can reserve a gap between the lightning arrester and the first support rod 3, facilitating the removal and installation of the connecting bolt 17. At the same time, the height of the upper support block 110 is only slightly greater than the distance between the first support rod 3 and the support frame 2, which can be 1-2 mm higher, and the height of the lower support block 120 is also only slightly greater than the distance between the second support rod 4 and the support frame 2, which can also be 1-2 mm higher. This design can avoid the height difference between the lightning arrester and the first support rod 3 being too large, otherwise when installing the connecting bolt 17 between them, the connecting bolt 17 will cause the first support rod 3 to be bent when tightened, thereby causing the first support rod 3 to be bent and broken. The same applies to the second support rod 4.

[0041] Further, as shown in the drawings, Figure 1 In order to facilitate the installation of the sliding positioning assembly and keep the height of the adjusting support rod flat, the sliding positioning assembly in the embodiment includes a positioning bolt 15 and a positioning sleeve 16. The positioning bolt 15 is inserted into the track groove 5 through the adjusting support rod, the positioning sleeve 16 is installed on the positioning bolt 15, and the positioning sleeve 16 is arranged between the adjusting support rod and the annular track 1.

[0042] It should be noted that the positioning sleeve 16 is equivalent to a nut, which can lock the positioning bolt 15 and is installed between the adjusting support rod and the ring track 1, and can support the first support rod 3 by the positioning sleeve 16 and the upper pad 11 to keep the first support rod 3 flat, and can support the second support rod 4 by the positioning sleeve 16 and the lower pad 12 to keep the second support rod 4 flat, which is beneficial to improve the connection stability between the first support rod 3 and the lightning arrester and the connection stability between the second support rod 4 and the support platform 20.

[0043] Further, as shown in Figure 1 In order to facilitate the installation position of the connecting bolt 17 between the lightning arrester and the first support rod 3 and the installation position of the connecting bolt 17 between the support platform 20 and the second support rod 4, the first adjusting hole 8 and the second adjusting hole 9 are strip-shaped holes in the embodiment.

[0044] Further, as shown in Figure 1 In order to facilitate manual adjustment of the adjusting support rod, the length of each adjusting support rod exceeds the edge of the ring track 1 in the embodiment, and the excess part forms an adjusting handle 18, and the user can hold the adjusting handle 18 to rotate the adjusting support rod.

[0045] Working principle:

[0046] In use, the positions of each first support rod 3 and second support rod 4 are adjusted respectively, the positions of the first support rod 3 and the second support rod 4 on the ring track 1 are locked by the sliding positioning assembly, the connecting bolt 17 is inserted into the mounting hole on the lightning arrester base 19 and the first adjusting hole 8 on the first support rod 3, and locked by the connecting nut, and the other connecting bolt 17 is inserted into the mounting hole on the support platform 20 and the second adjusting hole 9 on the second support rod 4, and locked by the connecting nut, so that the installation and connection of the lightning arrester and the support platform 20 are completed.
