Description

Technical Field

[0001] The invention belongs to the technical field of power grids, and in particular relates to a modular multifunctional centralized cable branch box. Background Art

[0002] The main function of the cable branch box is to branch or transfer cables. Currently, most cable branch boxes have four outlets, but in actual use on site, each outlet cannot be effectively utilized, resulting in a large waste of resources. During on-site construction, cables need to be laid from a cable branch box to each electric energy metering box branch, and the construction cost is high and the construction is cumbersome. Distribution facilities such as centralized meter boxes belong to the assets of the power company, and the power company will be responsible for unified operation and maintenance in the future. At present, the layout of underground cable branch boxes, centralized meter boxes and other distribution facilities is scattered, and faults cannot be handled in time. Summary of the invention

[0003] The object of the present invention is to provide a modular multifunctional centralized cable branch box to solve the problems existing in the prior art.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular multifunctional centralized cable branch box, comprising at least two cable branch boxes, a fixed part is installed on one side of the cable branch box, and a movable part is installed on the other side, and two adjacent cable branch boxes are connected together through the fixed part and the movable part.

[0005] Preferably, the number of the fixed part and the number of the movable part are two respectively and they are arranged in parallel.

[0006] Preferably, a fixing part U-shaped groove is provided on the fixing part, a moving part boss is provided on the moving part, a moving part cutting groove is provided between the moving part boss and the moving part, and the moving part cutting groove cooperates with the fixing part U-shaped groove.

[0007] Preferably, bolt holes are respectively provided on both sides of the fixing member and the movable member, and bolts pass through the bolt holes to fix the fixing member and the movable member on both sides of the cable branch box respectively.

[0008] The beneficial effects of the present invention are: first, saving investment funds. By integrating the branching function of the cable branch box into the incoming switch room of the electric energy metering box, waste of resources is avoided and repeated investment in equipment is reduced.

[0009] Second, reduce the route length. Improve the existing decentralized installation of centralized meter boxes to centralized installation, saving the cost of repeatedly installing cable trays and laying cable lines, and greatly reducing the construction workload.

[0010] Third, it is easy for later maintenance. The improved integrated meter box replaces the original cable branch box and is installed in a ring. On the premise of ensuring that the power supply reliability is the same as the original standard, it reduces the difficulty of later operation and maintenance, reduces the investment in later operation and maintenance personnel, and saves operation and maintenance costs.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0020] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0021] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0022] like Figure 1-Figure 7 As shown, a modular multifunctional centralized cable branch box is described. The present invention takes four cable branch boxes as an example, namely, a first cable branch box 1, a second cable branch box 2, a third cable branch box 3 and a fourth cable branch box 4. Each cable branch box is equipped with two movable parts 6 on the left side; each cable branch box is equipped with two fixed parts 5 on the right side; the two fixed parts 5 on the right side of the third cable branch box 3 are connected to the two movable parts 6 on the left side of the second cable branch box 2; similarly, the movable part 6 on the left side of the second cable branch box 2 is connected to the fixed part 5 on the right side of the first cable branch box 1; similarly, the fixed part 5 on the right side of the third cable branch box 3 is connected to the movable part 6 on the left side of the fourth cable branch box 4; and so on. According to site requirements, multiple or N cable branch boxes are connected in series, integrated into the switch room and then powered by branches.

[0023] A fixing U-shaped groove 7 is designed on the fixing part 5; a movable part boss 9 and a movable part groove 8 are designed on the movable part 6; when the fixing part 5 on the right side of the third cable branch box 3 is connected with the movable part 6 on the left side of the second cable branch box 2, the movable part 6 is hung on the fixing part 5; that is, the movable part groove 8 cooperates with the fixing U-shaped groove 7; the movable part boss 9 is fully positioned and cannot move left and right.

[0024] This design has a reasonable structure and strong workmanship. It can realize the transformation of the current power lines supporting charging facilities. By setting up new cable branch boxes, erecting bridges, and laying cables, the community power supply is introduced from the ground civil engineering station along the underground garage vehicle passages, stairwells, etc. into the underground garage. The cable branch boxes are set in the public areas on the ground or the public walls of the underground garage partitions. It is suitable for batch additions of distributed modular multifunctional centralized meter boxes underground in residential areas. After the research project is completed, the centralized meter will be integrated with the cable branch boxes, which will greatly reduce the investment cost and the difficulty of route coordination. It also has subsequent expandable functions. Ninghe Company will use it as a pilot unit and will later promote it to other power supply companies in Tianjin.

[0025] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
