Description
Technical Field
[0001] The present invention relates to the technical field of power distribution network racks, and in particular to a power distribution network rack used for low-carbon planning of power distribution networks. Background Art
[0002] With the development of science and technology, in order to meet the needs of low-carbon planning, people have begun to use more and more new energy equipment in their daily lives. With the popularization of new energy equipment, in order to meet the demand for new energy power supply, it is necessary to build a new energy distribution network. When the distribution network is transmitting electricity, it is necessary to set up distribution network racks along the way to support and fix the wires. The distribution network racks installed in residential areas are usually utility poles, that is, the utility poles are fixed with utility racks to support, limit or connect the wires.
[0003] With the popularization of new energy equipment and the increasing household electricity consumption, additional lines are needed to meet the current demand for increased power supply. However, the existing utility poles still have the following deficiencies when adding lines:
[0004] 1. Existing utility poles are often single-body structures. The support and connection of cables rely entirely on the installation of additional supports and connectors on the upper part of the poles. However, since the height of the utility poles is fixed, if there are too many supports or connectors originally installed on the poles, they cannot meet the requirements for the installation of new supports or connectors. Therefore, the utility poles need to be re-erected to complete the addition of new lines, which wastes financial and material resources.
[0005] 2. The installation of supports or connectors on existing utility poles relies entirely on bolts or clamps. When new lines need to be installed, workers not only need to carry clamp bolts and cable supports or connectors to climb, but also need to drill holes in the utility poles again for installation, which is time-consuming and labor-intensive.
[0006] 3. When installing or connecting cables, it is often necessary to install a variety of insulating protection structures on the supports or connectors. These components are often installed at high altitudes by workers after climbing to the top of the poles, which not only brings great difficulty to the workers, but also poses certain safety hazards.
[0007] Therefore, there is an urgent need for a distribution network frame that can overcome the above-mentioned shortcomings. Summary of the Invention
[0008] In order to overcome the shortcomings of the background technology, the present invention discloses a distribution network rack for low-carbon planning of distribution networks. The present invention can complete the installation of most cable connection support devices on the ground through multiple detachable series-connected installation rods. Subsequently, the cables can be supported and connected conveniently and efficiently by simply connecting the installation rods in series.
[0009] To achieve the above object, the present invention adopts the following technical solutions:

The cable enters through the open end of the hollow tube and passes through the two top plates in turn to limit the cable in an S-shaped elastic resistance, and then passes through the through hole to be connected to the connecting piece. A connecting cable for connecting the two cables is provided between the two connecting pieces. A support insulator capable of axially moving and adjusting the support rod is detachably installed on the upper part of the support rod. A support mechanism for supporting the cable and protecting the cable from swaying is detachably installed on the upper end of the support insulator. The support mechanism includes a U-shaped frame, and the two inner side walls of the U-shaped frame are provided with limit plates for elastically clamping the cable.
[0011] Furthermore, an installation groove A is provided on the upper end face of the utility pole, and a sunken screw hole is provided on the outer side wall of the installation groove A and passes through the side wall of the installation groove A. A mounting seat is provided at the lower end of the mounting pole and matched with the installation groove A, and a screw hole is provided on the side wall of the mounting seat and matched with the sunken screw hole, and a sunken screw is provided in the corresponding sunken screw hole.
[0012] Furthermore, the upper end surface of the mounting rod is provided with a mounting groove B that is compatible with the mounting seat, and the mounting seat located at the lower end of the upper mounting rod is inserted into the mounting groove B located at the upper end of the lower mounting rod. The outer wall of the mounting groove B is also provided with a sunken screw hole that passes through the side wall of the mounting groove B and corresponds to the screw hole on the side wall of the mounting seat.
[0013] Furthermore, a plurality of reinforcing ribs are provided in the installation groove A and the installation groove B for reinforcing and supporting the side walls thereof, and a plurality of bayonet holes corresponding one to one with the plurality of reinforcing ribs are provided on the installation seat.
[0014] Furthermore, several sockets A are evenly distributed on the end face of the slot of the installation slot A, and several plug-in rods are provided on the lower end face of the installation rod, which are plugged into the sockets A one-to-one. Several sockets B are evenly distributed on the end face of the slot of the installation slot B, which are matched with the plug-in rods one-to-one.
[0015] Furthermore, a cover plate is detachably mounted on the upper portion of the mounting slot B, and a mounting seat and an insertion rod are also provided on the lower portion of the cover plate.
[0016] Furthermore, the sealed end of the hollow tube is provided with two corresponding connecting plates, and the two connecting plates are respectively provided with connecting screws connected to the two sides of the connecting piece.
[0017] Furthermore, a groove is provided on the upper surface of the support rod along the axial direction of the support rod, and several through holes A are provided on both side walls of the groove at corresponding intervals along the axial direction of the groove.

[0020] Compared with the prior art, the present invention has the following advantages: by using several detachable serially connected mounting rods, the traditional method of requiring workers to climb to the height of the utility pole and then perform welding or screw installation is avoided. Not only can workers complete the installation of cable connectors or supports on the ground, but they only need to lift and assemble them on the utility pole for installation, which greatly reduces the operating difficulty of workers. Moreover, when additional cable supports or connections are required, the mounting rods only need to be stacked and installed.
[0021] By setting up a traction mechanism and using S-shaped elastic limit on the cable, when the cable swings, it can not only avoid pulling the cable head during the cable swing process, affecting the connection stability of the cable head, but also relieve the force of the cable swing, greatly improving the safety and stability of the cable connection;
[0022] By setting up a support mechanism, the cable can be elastically limited and supported, ensuring stable support of the cable. At the same time, it can also relieve the force of the swaying cable and reduce the damage to the supporting insulator, greatly improving the support stability of the cable.
[0023] By setting up a detachable and adjustable mounting block, the installation can be adjusted according to actual needs to meet the support requirements of multiple cables;
[0024] By setting up the reinforcing ribs, the structural strength of the mounting pole can be greatly improved, thus providing a strong guarantee for the subsequent stable support and connection of the cables;
[0025] The present invention uses multiple detachable installation rods connected in series, which avoids the traditional method of requiring workers to climb to a high altitude and then carry out tedious installation of multiple components when installing cables. Workers can complete the installation of most cable connection support devices on the ground. Subsequently, they only need to connect the installation rods in series to conveniently and efficiently support and connect the cables. The present invention has a simple structure and is easy to operate and use, which provides great convenience for workers in installing and connecting cables and greatly reduces the operating difficulty of workers.
