Description

Technical Field

[0001] This utility model relates to the field of cable pipe technology, and in particular to a power cable pipe. Background Technology

[0002] Power cable conduits are pipes used to protect power cables. In road construction, building construction and other scenarios, cable conduits can not only prevent cables from being squeezed, collided with or damaged by digging tools, but also isolate cables from corrosive soil, groundwater or chemical gases, thus extending the service life of the cables.

[0003] When the air humidity in the environment where the cable conduit is located is high and the temperature of the outer wall of the conduit is lower than the dew point temperature of the air, water vapor in the air will condense into small water droplets on the outer wall of the conduit, forming condensate. When the cable is buried, water wells are provided on both sides of the buried conduit end. The cable conduit has a certain angle so that the condensate is subjected to gravity and flows into the water well along the slope of the buried conduit.

[0004] However, when the cable conduit is tilted at a certain angle to drain condensate, it is suitable for laying shorter cables. If the cable is laid for a longer length, the tilted cable conduit will result in a deeper laying depth. The increased depth will increase the amount of excavation work and difficulty, require more earthwork to be handled, and also increase construction costs. Utility Model Content

[0005] The purpose of this utility model is to provide a power cable conduit, which, when used with this device, solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a power cable conduit, including a cable conduit body, a reinforcing inner lining ring provided on the inner side wall of the cable conduit body, a flow guide groove provided at the middle position of the bottom end inside the cable conduit body, and a limit ring provided at the middle position inside the cable conduit body.

[0007] Preferably, the inner wall of the cable conduit body is provided with an installation groove, the installation grooves are evenly spaced on the inner wall of the cable conduit body, and a reinforcing inner lining ring is provided inside the installation groove.

[0008] Preferably, one end of the guide channel is higher than the other end of the guide channel, and the guide channel has a certain slope.

[0009] Preferably, the limiting ring is located at the middle position of both ends inside the cable pipe body, and fixing blocks are fixed on both sides of the limiting ring, and the fixing blocks are fixed on the inner side wall of the cable pipe body.

[0010] Preferably, the limiting rings are symmetrical at both ends of the centerline inside the cable conduit body, and the fixing blocks are symmetrically distributed on both sides of the centerline of the limiting rings.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The present invention provides a power cable conduit, which provides a guide groove at the bottom of the conduit body. When multiple sets of cable conduits are connected, the lower end of one set of guide grooves is aligned with the higher end of another set of guide grooves. The slope of the guide grooves themselves allows condensate to flow from high to low and be discharged. This eliminates the need for the cable conduit to be tilted during installation, and the depth of the laying groove can be kept the same, which greatly saves excavation costs and installation difficulty, and improves construction efficiency.

[0013] 2. The power cable conduit provided by this utility model places the cable in a limiting ring in the middle of the main body of the conduit, which effectively avoids direct contact between the cable and the conduit wall. Since the condensate in the conduit mainly adheres to the conduit wall, it minimizes the corrosion of the cable by water, reduces the risk of cable insulation performance degradation due to the conductivity of water, ensures long-term stable operation of the cable, and extends the service life of the cable.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-4This utility model discloses a power cable conduit, comprising a cable conduit body 1, a reinforcing inner lining ring 2 provided on the inner side wall of the cable conduit body 1, a flow guide groove 3 provided at the middle position of the bottom end of the cable conduit body 1, a limiting ring 4 provided at the middle position of the inner side wall of the cable conduit body 1, an installation groove 21 provided on the inner side wall of the cable conduit body 1, the installation groove 21 being equally spaced on the inner side wall of the cable conduit body 1, the reinforcing inner lining ring 2 being provided inside the installation groove 21, one end of the flow guide groove 3 being higher than the other end of the flow guide groove 3, the flow guide groove 3 having a certain slope, the limiting ring 4 being provided at the middle position of both ends of the inner side of the cable conduit body 1, the fixing blocks 41 being fixed on both sides of the limiting ring 4, the fixing blocks 41 being fixed on the inner side wall of the cable conduit body 1, the limiting ring 4 being symmetrical at both ends of the centerline of the inner side of the cable conduit body 1, and the fixing blocks 41 being symmetrically distributed on both sides of the centerline of the limiting ring 4.

[0022] Working principle: When installing the main body 1 of the cable conduit, align the lower end of one set of guide channels 3 with the higher end of another set of guide channels 3. Connect multiple sets of main bodies 1 in this way. There is no need to tilt the main body 1 of the cable conduit to a certain angle. Condensate enters the guide channel 3 and flows from the higher point to the lower point in the guide channel 3, thus draining the condensate. There is no need to tilt the main body 1 of the cable conduit. When laying the main body 1 of the cable conduit, the depth of the laying channel can be kept the same. Compared with tilting the cable conduit, which makes the laying depth deeper and increases the amount of excavation and difficulty, this method saves costs and laying difficulty.

[0023] Since the condensate generated inside the pipe mainly adheres to the pipe wall, when laying the main body 1 of the cable conduit, the cable is placed in the limiting ring 4. The limiting ring 4 keeps the cable in the middle position inside the main body 1 of the cable conduit. Even if a lot of condensate accumulates inside the pipe, as long as the cable is in the center position, the corrosion of the cable by water can be reduced to the greatest extent, and the cable can be prevented from directly contacting the condensate, thereby reducing the risk of cable insulation performance degradation due to the conductivity of water.

[0024] Meanwhile, multiple sets of reinforcing inner rings 2 are provided on the inner wall of the cable pipe body 1. When the cable pipe body 1 is subjected to external pressure, the reinforcing inner rings 2 can play an auxiliary support role, thereby protecting the cable inside the cable pipe body 1 and further improving the protective effect of the cable pipe body 1.
