Description

Technical Field

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

[0002] When low-voltage cables are run underground, rigid power conduits are often used to protect them from being squeezed and damaged. However, due to imperfect drainage structures, the power conduits are often poorly sealed, allowing groundwater to seep into them and corrode the internal cables. Furthermore, when the conduits deform, they can squeeze the internal cables, causing them to break. Therefore, these problems need to be addressed. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drainage type power pipe, comprising an outer pipe and an inner pipe, wherein a drainage mechanism is installed on the outer pipe, and a fixed buffer mechanism is installed between the outer pipe and the inner pipe; the drainage mechanism includes an annular water inlet groove formed on the inner wall of the outer pipe and a drainage plate installed on the outer pipe, wherein a flow guide groove is formed at the bottom end of the inner wall of the outer pipe, and the flow guide groove communicates with the bottom end of the annular water inlet groove.

[0005] Preferably, multiple drainage holes are provided at equal intervals on both the guide channel and the annular water inlet channel. The drainage holes are truncated cones, and the diameter of the through hole at the inner wall end of the drainage hole is larger than the diameter of the through hole at the outer wall end.

[0006] Preferably, the drainage plates are installed at equal intervals around the outer pipe, the drainage plates have hook-shaped arcs, and the drainage plates are located outside the drainage holes.

[0007] Preferably, the fixed buffer mechanism includes multiple springs fixed to the periphery of the inner wall of the outer tube, with a fixing block fixed to the other end of each spring, and multiple load-bearing rings fixed to the other end of each fixing block, and the load-bearing rings are sleeved on the outer wall of the inner tube.

[0008] Preferably, a limiting sleeve is fitted inside the inner tube, and multiple mounting holes are provided through the limiting sleeve, with wires installed in each of the multiple mounting holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of drainage channel, drainage hole and drainage plate, facilitates the flow of water to the drainage hole after water seeps into the outer pipe, thereby preventing groundwater from seeping in and corroding the wires; furthermore, the setting of load-bearing ring and spring facilitates the reduction of the impact on the inner pipe when subjected to external impact, and the load-bearing ring provides support when the appearance is deformed, thereby preventing the inner pipe from deforming and preventing the internal wires from being squeezed; ultimately, it solves the problem of groundwater seeping into the power pipe and corroding and damaging the internal wires and squeezing the internal wires, causing wire damage.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: See Figure 1-4This utility model discloses a drainage-type power conduit, comprising an outer pipe 1 and an inner pipe 2. The outer pipe 1 facilitates the installation of a drainage mechanism, while the inner pipe 2 facilitates the installation of electrical wires 11. The drainage mechanism is installed on the outer pipe 1, and a fixed buffer mechanism is installed between the outer pipe 1 and the inner pipe 2. The drainage mechanism includes an annular water-guiding groove 4 formed on the inner wall of the outer pipe 1 and a drainage plate 3 installed on the outer pipe 1. The annular water-guiding groove 4 facilitates the drainage of infiltrated rainwater, and the drainage plate 3 facilitates drainage in conjunction with drainage holes 5. A guide groove 10 is formed at the bottom of the inner wall of the outer pipe 1, which facilitates the drainage of liquid that has not been discharged from the annular water-guiding groove 4. The guide groove 10 is connected to the bottom of the annular water-guiding groove 4, and multiple drainage holes 5 are equally spaced on both the guide groove 10 and the annular water-guiding groove 4, which facilitate the removal of water from the inside of the outer pipe 1. The drainage holes 5 are truncated cones, and the diameter of the through hole at the inner wall end of the drainage hole 5 is larger than the diameter of the through hole on the outer wall.

[0018] In this utility model, drainage plates 3 are equidistantly installed around the outer pipe 1. The drainage plates 3 have hook-shaped arcs to prevent soil from entering and clogging the drainage holes 5 when buried underground. The fixed buffer mechanism includes multiple springs 7 fixed to the inner wall of the outer pipe 1. The springs 7 help to reduce the vibration of the outer pipe 1 on the inner pipe 2. The other end of each of the multiple springs 7 is fixed to a fixing block 8, which facilitates the connection between the inner pipe 2 and the outer pipe 1. The other end of each fixing block 8 is fixed to multiple load-bearing rings 9, which facilitate the support and protection of the inner pipe 2. The multiple load-bearing rings 9 are all sleeved on the outer wall of the inner pipe 2. The inner side of the inner pipe 2 is fitted with a limiting sleeve 6, which prevents the internal wires 11 from rubbing against each other. The limiting sleeve 6 has multiple mounting holes, and wires 11 are installed in each of the multiple mounting holes.

[0019] Working principle: When this utility model is used, if the device is buried underground, after groundwater seeps into the inner wall of the outer pipe 1, it is guided to the drain hole 5 through the internal annular water channel 4 and discharged. The drain hole 5 is larger inside and smaller outside, which facilitates discharge and has a certain function of preventing liquid seepage. The drain plate 3 can form a cavity with the outer side of the outer pipe 1 to prevent soil from clogging the drain hole 5 during burial. The built-in spring 7 can absorb vibration when the ground vibrates slightly to avoid affecting the inner pipe 2. When the outer pipe 1 is broken due to crustal movement, the load-bearing ring 9 will act as a protective support for the inner pipe 2 to prevent it from being damaged. When the device is installed on the ground, the drain plate 3 can guide rainwater from above to the drain plate 3 below during rainy days, and finally discharge the rainwater through the bottom end to prevent rainwater from seeping into the inner wall of the outer pipe 1 from the drain hole 5.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
