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 poles still have the following deficiencies when adding lines: 1. Existing electric poles are often single pole structures. The support and connection of cables completely rely on installing additional supports and connectors on the upper part of the electric poles. However, since the height of the electric poles is fixed, if there are too many supports or connectors originally installed on the electric poles, it is impossible to install new supports or connectors. In this case, the electric poles need to be re-erected to complete the addition of new lines, which wastes financial and material resources. 2. The installation of the existing support or connector on the electric pole is completely dependent on bolts or clamps. When a new line needs to be installed, not only do the workers need to carry the clamp bolts and cable support or connectors to climb, but they also need to drill holes in the electric poles again for installation, which is time-consuming and laborious. 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; Therefore, there is an urgent need for a distribution network frame that can overcome the above-mentioned shortcomings. Summary of the invention

[0004] 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.

At the same time, it can also relieve the force of the swaying cable and reduce the damage to the supporting insulator, thus greatly improving the support stability of the cable. By setting a detachable and adjustable mounting block, the installation can be adjusted according to actual needs to meet the support requirements of multiple cables; By setting the reinforcing rib plate, 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 cable; The present invention avoids the tedious installation of multiple components required for traditional cable installation and support by using multiple detachable installation rods in series. The workers can complete the installation of most cable connection support devices on the ground, and then 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, which greatly facilitates the workers in installing and connecting the cables and greatly reduces the operating difficulty of the workers.
