Description

Technical Field

[0001] The utility model relates to the technical field of power distribution hardware, in particular to a fixed connecting plate for a large height difference power distribution line. Background Art

[0002] Distribution lines refer to lines that send electricity from step-down substations to distribution transformers or from distribution substations to electricity users. Power fixed couplings are important components used to connect and fix power equipment in power systems. In power engineering, couplings are mainly used in overhead power lines and substations to assemble suspension insulator strings, fix split conductors and insulator strings, or to fix multiple guy wires in parallel. There are many types of couplings, which can be divided into multiple types according to different design and usage requirements, such as L-type couplings, LF-type couplings, LV-type couplings, LS-type couplings, etc. The design and selection of couplings need to be determined according to the specific requirements of the power system, load conditions, environmental factors, and safety standards. Correct coupling selection and installation are essential to ensure the reliability and safety of the power system.

[0003] When a transmission line is erected, there is usually a large height difference due to the different terrain, especially in mountainous areas, resulting in a height difference on both sides of the line. Most of the existing hardware is one-piece, which makes it inconvenient to adjust the installation spacing during use, which easily reduces the applicability of the hardware during use. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a fixed connecting plate for a large height difference distribution line, so as to solve the problem that most of the existing hardware are integrally formed and it is not convenient to adjust the installation spacing during use, which easily reduces the applicability of the hardware during use.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a fixed connecting plate for a large height difference distribution line, comprising a mounting main board and a limit adjustment rod, a mounting hole 1 is provided on the top of the mounting main board, and an adjustment through hole is provided on the lower half of the mounting main board, a double-headed screw is installed through the bottom of the mounting main board, and a fixing nut 1 is installed at both ends of the double-headed screw, the limit adjustment rod is installed on the double-headed screw, and a fixing screw is installed on the limit adjustment rod, a fixing nut 2 is installed on the fixing screw, and a mounting hole 2 is provided at the bottom of the limit adjustment rod away from the mounting main board.

[0006] The beneficial effect of the utility model is that when the installation spacing needs to be adjusted, the fixing nut 2 and the fixing screw are unscrewed, and the spacing between the limit adjustment rods and the limit adjustment rods can be adjusted through the circumferentially distributed adjustment holes in conjunction with the fixing screw and the fixing nut 2, so that the installation spacing can be adjusted as needed to ensure the applicability of the device during use.

[0007] To facilitate the adjustment of the limit adjustment rod:

[0008] As a further improvement of the above technical solution: the adjustment through holes are circumferentially distributed in the lower half of the mounting mainboard.

[0009] The beneficial effect of this improvement is: when the installation spacing needs to be adjusted, the fixing nut 2 and the fixing screw are unscrewed, and the spacing between the limit adjustment rods can be adjusted through the circumferentially distributed adjustment holes, so that the installation spacing can be adjusted as needed, which can facilitate the installation of the limit adjustment rod.

[0010] To facilitate the installation of the double-ended screw:

[0011] As a further improvement of the above technical solution: the double-headed screw and the mounting main board are arranged perpendicular to each other.

[0012] The beneficial effect of this improvement is that the mutually perpendicular arrangement allows the double-headed screw to penetrate the mainboard for installation, making it convenient to install the limit adjustment rod above the double-headed screw, and can also make the device more reliable and stable during subsequent use.

[0013] To facilitate the installation of the wires:

[0014] As a further improvement of the above technical solution: the number of the limit adjustment rods is two, and a through hole is opened in the middle portion of the limit adjustment rod.

[0015] The beneficial effect of this improvement is that multiple wires can be fixed in parallel through two limit adjustment rods, and the through hole can facilitate the fixing screw to pass through the limit adjustment rod and the adjustment through hole to fix the position of the limit adjustment rod, thereby facilitating the adjustment of the position of the limit adjustment rod.

[0016] To reduce friction between the mounting holes and the connecting parts:

[0017] As a further improvement of the above technical solution: both ends of the mounting hole 1 are chamfered.

[0018] The beneficial effect of this improvement is that the friction between the mounting hole and the connecting piece can be effectively reduced by setting the rounded corners, thereby increasing the durability of the device.

[0019] To facilitate the fixation of the limit adjustment rod position:

[0020] As a further improvement of the above technical solution: the fixing screw and the second fixing nut are threadedly connected.

[0021] The beneficial effect of this improvement is: after the limit adjustment rod is rotated along the double-headed screw to a suitable angle, the fixed screw is used to pass through the adjustment hole, and then through the limit adjustment rod, and then fixed to the bottom of the mounting main board using the fixed nut 2. The threaded connection can make the fixation of the limit adjustment rod position by the fixed nut 2 and the fixed screw more reliable and firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0029] like Figure 1-5As shown, a large height difference distribution line fixed connecting plate includes a mounting main board 1 and a limit adjustment rod 3, the upper part of the mounting main board 1 is provided with a mounting hole 11, and the lower part of the mounting main board 1 is provided with an adjustment through hole 12, a double-headed screw 2 is installed through the lower part of the mounting main board 1, and a fixing nut 21 is installed at both ends of the double-headed screw 2, the limit adjustment rod 3 is installed on the double-headed screw 2, and a fixing screw 31 is installed on the limit adjustment rod 3, and a fixing nut 2 32 is installed on the fixing screw 31, and a mounting hole 2 33 is opened at the bottom of the limit adjustment rod 3 away from the mounting main board 1, when the installation spacing needs to be adjusted Unscrew the fixing nut 2 32 and the fixing screw 31, and adjust the spacing between the limit adjustment rod 3 and the limit adjustment rod 3 through the circumferentially distributed adjustment through holes 12 in cooperation with the fixing screw 31 and the fixing nut 2 32, so that the installation spacing can be adjusted as needed to ensure the applicability of the device during use. The adjustment through holes 12 are circumferentially distributed on the lower half of the installation main board 1. When the installation spacing needs to be adjusted, unscrew the fixing nut 2 32 and the fixing screw 31, and adjust the spacing between the limit adjustment rod 3 and the limit adjustment rod 3 through the circumferentially distributed adjustment through holes 12, so that the installation spacing can be adjusted as needed. The double-headed screw rod 2 and the mounting main board 1 are arranged perpendicular to each other. The perpendicular arrangement can facilitate the installation of the limit adjustment rod 3 above the double-headed screw rod 2 after the double-headed screw rod 2 passes through the mounting main board 1, and can also make the device more reliable and stable during subsequent use. The number of the limit adjustment rods 3 is two, and a through hole is opened in the middle part of the limit adjustment rod 3. Multiple wires can be fixed in parallel through the two limit adjustment rods 3. The fixing screw 31 can pass through the limit adjustment rod 3 and the adjustment through hole 12 to fix the position of the limit adjustment rod 3, thereby The position of the limit adjustment rod 3 can be easily adjusted. The two ends of the mounting hole 11 are chamfered. The chamfered setting can effectively reduce the friction between the mounting hole 11 and the connecting piece, thereby increasing the durability of the device. The fixing screw 31 and the fixing nut 2 32 are threadedly connected. After the limit adjustment rod 3 is rotated to a suitable angle along the double-headed screw 2, the fixing screw 31 is used to pass through the adjustment through hole 12, and then through the limit adjustment rod 3. After that, the fixing nut 2 32 is used to fix it under the mounting main board 1. The threaded connection can make the fixing of the position of the limit adjustment rod 3 by the fixing nut 2 32 and the fixing screw 31 more reliable and firm.

[0030] The working principle of the utility model is as follows: when using the device, the double-headed screw 2 is passed through the installation main board 1, and the limit adjustment rod 3 is installed on the two ends of the double-headed screw 2, and then the two ends of the double-headed screw 2 are covered with a fixing nut 1 21 to complete the installation of the limit adjustment rod 3. At this time, the limit adjustment rod 3 is rotated along the double-headed screw 2 to a suitable angle, and then the fixing screw 31 is used to pass through the adjustment through hole 12, and then through the limit adjustment rod 3, and then fixed to the bottom of the installation main board 1 with a fixing nut 2 32 to complete the installation of the device. At this time, the suspension insulator string can be assembled, and the split conductor and the insulator string can be fixed, or it can be used for parallel fixation of multiple pull wires. When the installation spacing needs to be adjusted, the fixing nut 2 32 and the fixing screw 31 are unscrewed, and the spacing between the limit adjustment rod 3 and the limit adjustment rod 3 can be adjusted through the circumferentially distributed adjustment through holes 12 in conjunction with the fixing screw 31 and the fixing nut 2 32, so that the installation spacing can be adjusted as needed, and after the limit adjustment rod 3 and the limit adjustment rod 3 coincide with each other, it can be adjusted according to the number of conductors.
