AI Technical Summary
The existing cable coil wells cover a large area, resulting in waste of land resources, and are difficult to arrange especially when there is limited space around cities and substations.
The circular double loop cable well design is adopted, and a circular double loop is formed through the cable terminal tower and the two tower legs. The different length differences on both sides of the tower legs are used as the cable cable length, and the cable length is reserved at the middle joint of the cable to achieve a cable margin of 6m.
The area of the cable well is reduced by about 20%, suitable for complex terrain and easy construction, and is suitable for limited space environments around cities and substations.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable winding wells, in particular to a circular double-circuit cable winding well. Background Art
[0002] Power cable power supply technology is relatively mature. In urban areas, transportation hubs, and other locations, power cables have essentially replaced traditional overhead lines. However, intermediate joints and terminals are among the most critical components of a cable. Their installation method and operating environment directly impact the cable's reliable and stable operation. Furthermore, to ensure reconnection in the event of cable damage during use, a cable margin of at least 3m (half a turn) is typically required at the intermediate joint well and terminal.
[0003] Existing cable winding shafts generally have a semicircular winding area on one side of the cable's forward direction. Generally, a cable winding shaft occupies about 80 square meters.
[0004] In order to ensure a sufficient cable turning radius, the existing cable winding wells occupy too large an area and are too expensive. Considering that most cables are used in cities and around substations, there is limited space on roads and green belts, and there is no space for arranging conventional cable winding wells. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide a circular double-circuit cable winding pit that can minimize the occupation of land resources while meeting the cable turning radius.
[0006] The utility model is realized by the following method: a circular double-circuit cable winding shaft, comprising a cable terminal tower, wherein the cable terminal tower and two tower legs respectively form a circular double-circuit cable winding shaft, and the cable is laid to the terminal tower, and the different length differences between the left and right sides of the tower legs are used as the cable winding length.
[0007] Furthermore, the average cable margin is achieved to 6m. At the same time, the cable is connected to the circular double-circuit cable well, and the cable length is reserved at the middle joint of the cable through this circular double-circuit cable well.
[0008] The beneficial effects of the utility model are as follows: the utility model can reduce the floor space of the cable winding well, which is about 20% less than that of the conventional cable winding well, and is suitable for various complex terrain conditions; it is convenient for setting out and facilitating construction. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION
[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] See also Figure 1 As shown, the utility model provides an embodiment: a circular double-circuit cable winding shaft, in which the center of the cable terminal tower 1 and the two tower legs respectively form a circular double-circuit cable winding shaft, and the cable 2 is laid to the terminal tower. The different length differences laid on the left and right sides of the tower legs are used as the cable winding length. The average cable margin of this method can be about 6m. At the same time, the position of the cable accessing the circular double-circuit cable winding shaft can be flexibly adjusted according to the on-site terrain conditions. The cable length can also be reserved at the middle joint of the cable through this circular double-circuit cable winding shaft.
[0012] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
