Description

Technical Field

[0001] The utility model belongs to the technical field of river channel construction, and in particular relates to a comprehensive waterproof power cable for river channel construction. Background Art

[0002] With the continuous rapid development of my country's economy and the acceleration of urbanization, the scale of cities continues to expand, the existing urban areas are becoming saturated, and the demand for the construction of subway lines and urban infrastructure is increasing. At the same time, many cities in my country are built along rivers, and it is very common for rivers to pass through cities. This provides abundant water resources for urban development, but also brings many challenges to river construction. In the process of river construction, power cables are one of the indispensable and important equipment. They carry the important task of power transmission. However, traditional power cables have some inherent problems in design and application.

[0003] First, the cross-section of traditional power cables is usually circular, which is inconvenient when laid inside a river. Due to the complexity of river flow and the irregularity of the riverbed, the circular cable is easy to roll inside the river and is difficult to fix in place, which brings great difficulties to construction and maintenance.

[0004] Secondly, when traditional cables need to pass through a river channel, they are usually laid directly on the bottom of the river channel. Compared with laying on the surface of the river, laying cables on the bottom of the river channel is more susceptible to erosion by water flow and friction with objects such as riverbed rocks, which can cause damage and aging of the cables. In addition, due to the uneven bottom of the river channel, the cables are prone to bending during the laying process, which not only increases the difficulty of laying the cables, but also may lead to cable waste and increase construction costs.

[0005] Finally, existing power cables lack sufficient buffering capacity when subjected to external pressure. During river channel construction, cables may be subjected to various external pressures, such as water flow impact, construction machinery extrusion, etc. If the cables lack sufficient buffering capacity, these pressures can easily cause the cable conductors to break or be damaged, affecting the normal transmission of power.

[0006] Therefore, it is very necessary to invent a comprehensive waterproof power cable for river construction. Utility Model Content

[0007] The purpose of the utility model is to provide a comprehensive waterproof power cable for river construction to solve the problems mentioned in the background technology.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a comprehensive waterproof power cable for river channel construction, comprising an outer sheath, a reinforcing net, an inner sheath, a filling layer, a limiting frame, a conductor and an insulating layer, wherein the outer sheath is a flat structure, and a reinforcing net is fixed inside the outer sheath, wherein the inner sheath is fixed inside the reinforcing net, and the filling layer is fixed inside the inner sheath; a limiting frame is fixed inside the filling layer, wherein a plurality of conductors are fixed inside the limiting frame, and the outer side surfaces of the conductors are all wrapped with insulating layers; the reinforcing net adopts a mesh structure woven from a steel wire mesh.

[0010] Furthermore, the outer sheath includes a sheath, a steel plate and a float. The sheath is wrapped around the outer side of the reinforcing net, and a number of the steel plates are fixed inside the sheath. A float is fixed on the outer side of the sheath. Such an arrangement can make the cable float on the river water, thereby reducing the use length of the cable and, secondly, improving the structural strength of the cable.

[0011] Furthermore, the limiting frame includes a reinforcement sleeve, a connecting belt and a support frame. There are several reinforcement sleeves, wherein the number of the reinforcement sleeves is the same as the number of conductors, and conductors are fixed inside the reinforcement sleeves; the reinforcement sleeves are fixed inside the filling layer, and connecting belts are fixed between adjacent reinforcement sleeves, wherein a support frame is fixed inside the connecting belt. Such a setting can limit the position of the conductor and, secondly, can buffer external pressure.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The setting of the outer sheath of the utility model enables the buoy to make the cable float on the river water when the cable needs to pass through the inside of the river channel, so that the staff can confirm the position of the cable. The floating of the cable on the river water can reduce the use length of the cable compared to laying the cable on the bottom of the river. Secondly, the setting of the steel plate can improve the structural strength of the cable. In addition, since the shape of the outer sheath is a flat structure, it can prevent the cable from rolling inside the river channel.

[0014] 2. The setting of the limit frame of the utility model can limit the position of the conductor through the cooperation of the reinforcement sleeve, the connecting belt and the support frame when it is in use. Secondly, when subjected to external pressure, the connecting belt and the support frame can bend accordingly, thereby buffering the pressure. BRIEF DESCRIPTION OF THE DRAWINGS
