Description

Technical Field

[0001] The present invention relates to the technical field of electric power pipes, and in particular to an electric power pipe. Background Art

[0002] As economic development drives ever-increasing demand for electricity, new requirements are being placed on urban power transmission methods. Overhead lines, for example, not only have limited power transmission capacity, occupy a large area, and negatively impact the cityscape, but also offer limited space in urban power corridors, making them inadequate for the large number of overhead lines. To meet these demands, undergrounding overhead lines is increasingly being used, with substation cable access channels also being buried underground, leading to the widespread use of power conduits.

[0003] Currently, the primary construction method for power distribution pipes is cast-in-place construction using steel bars, protective pipes, and concrete. This method involves numerous on-site operations, resulting in slow construction and difficult quality control. Furthermore, cast-in-place concrete construction significantly impacts traffic and the environment, and many urban construction areas lack the necessary operating space for large equipment. Furthermore, power distribution pipes are located underground, and the movement of vehicles and rail transit above ground can cause vibrations in the pipes. Furthermore, in extreme disaster conditions, ground vibrations and subsidence can also affect the pipes, posing a threat to the safe operation of cables and causing economic losses. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric power pipe having the advantages of simple manufacturing process, easy installation and small weight, and can reduce the vibration of the cables in the pipe when the electric power pipe vibrates, thereby protecting the cables from damage.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] The electric power pipe includes at least two pipe sections and a support assembly. Each pipe section includes at least two stacked prefabricated pipe units. Each pipe unit has a plurality of pipe holes arranged at intervals. The pipe holes pass through the length direction of the pipe unit. Cable protection pipes are inserted into the pipe holes. Vibration damping parts are sleeved on the outside of the cable protection pipes. At least two pipe sections are connected in sequence along the length direction of the pipe unit, and the pipe holes are connected one by one to form a pipeline. The support assembly is supported at the bottom connection of two adjacent pipe sections.

[0007] Optionally, the support assembly includes a support portion and a fixed cone, the upper wall surface of the support portion abuts against the lower wall surface of the pipe section; the fixed cone is fixed on the lower wall surface of the support portion and extends downward.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0028] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0029] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation.

[0031] The following describes the preferred implementation of the power pipe provided by this embodiment with reference to the accompanying drawings. It should be noted that in the present invention, the first direction is Figure 1 、 Figure 3-Figure 5 The first direction is the X direction shown in Figure 1 and Figure 5 The Y direction shown in the figure, the third direction is Figure 1 、 Figure 3-Figure 5 The Z direction shown in .

[0032] refer to Figure 1 , Figure 1 This is a schematic diagram of the support assembly 300 provided in this embodiment after being assembled with the pipe body. The power pipe provided in this embodiment includes a pipe body and a support assembly 300. The pipe body is formed by butting together at least two pipe sections along their length. Each pipe section includes at least two stacked prefabricated pipe units 100. Each pipe unit 100 has multiple spaced-apart holes 120 extending along its length. Cable protection tubes 121 are inserted into the holes 120, and vibration dampers 122 are spaced outside the cable protection tubes 121. At least two pipe sections are butted together in sequence along their length, connecting these holes 120 one by one to form a pipe. The support assembly 300 is supported at the bottom connection point between two adjacent pipe sections. In this embodiment, the pipe units 100 are rectangular in shape, with multiple holes 120 spaced apart along a first direction. In this embodiment, there are three holes 120, spaced apart along the first direction. The first direction is the width of the pipe unit 100, the second direction is the length of the pipe unit 100, that is, the axial direction of the pipe hole 120, and the third direction is the thickness of the pipe unit 100. The second, third, and first directions are perpendicular to each other. The support assembly 300 is supported at the connection between two connected pipe sections. It can effectively protect the pipe body from being affected by ground settlement or vibration, prevent relative displacement of the pipe unit 100 due to vibration, and prevent damage to the cables inside the pipe unit 100.

[0033] Please refer to Figure 2The support assembly 300 provided in this embodiment includes a support portion 310 and a fixing cone 320. The upper wall of the support portion 310 abuts against the lower wall of the drainage pipe section; the fixing cone 320 is fixed to the lower wall of the support portion 310 and extends downward along a third direction. It is understood that the fixing cone can be inserted into the ground below when extended along the third direction to fix the support assembly to the ground. Inserting the fixing cone fixed to the support portion into the ground below the drainage pipe body can better fix the support assembly 300 to the ground, preventing the drainage pipe connection from breaking due to the loss of the soil layer below the drainage pipe, thereby threatening the safe operation of the cable, improving the installation stability and firmness of the power drainage pipe, and improving the durability of the prefabricated vibration-damping drainage pipe.

[0034] As a preferred embodiment, the support portion 310 is provided with a limit portion 311 at each end along the first direction, and the inner wall of the limit portion 311 abuts the outer wall of the drain pipe section. The provision of the limit portion 311 can stably secure the drain pipe body to the support assembly 300, further improving the installation stability of the power drain pipe, reducing cable shaking caused by ground vibration, and effectively protecting the internal cables from damage. It is conceivable that a certain distance can be left between the limit portion 311 and the outer wall of the drain pipe section to facilitate the installation of the drain pipe body on the support assembly 300.

[0035] Furthermore, support assembly 300 is made of wood. Wood has advantages such as light weight, good elasticity, impact resistance, and ease of processing. It also has low production costs, low energy consumption, and is non-toxic and pollution-free. When using wood in support assembly 300 of this embodiment, those skilled in the art will appreciate that the wood should be treated with an antiseptic. The wood selected can be logs, boards, or planks. Alternatively, plywood, fiberboard, or composite wood boards can be used to make support assembly 300.

[0036] Please refer to Figure 3 In the pipe hole 120 of the drain pipe unit 100 provided in this embodiment, a cable protection tube 121 is inserted, and a vibration damper 122 is provided on the outer spacer sleeve of the cable protection tube 121. As a preferred embodiment, the above-mentioned vibration damper 122 is an air spring. Compared with the metal spring, it has the advantages of small mass, good comfort, fatigue resistance, and long service life. It also has vibration reduction and noise reduction effects. When the drain pipe vibrates, the vibration damping airbag inside is squeezed and stretched to reduce the shaking of the cable, so as to achieve the purpose of vibration reduction, thereby ensuring the stable operation of the cable. Of course, it is conceivable that components with vibration reduction functions such as metal vibration damping springs and vibration damping air cushions can also be used. The use of the vibration damper 122 can reduce the relative friction between the cable protection tube 121 and the internal cable caused by shaking when the drain pipe unit 100 is subjected to external force and generates shaking, thereby effectively protecting the cable in the cable protection tube 121 from running stably and being damaged.

[0037] Furthermore, both ends of the cable protection tube 121 are provided with bell mouths, and the inner diameter of the small diameter end of the bell mouth is the same as the inner diameter of the cable protection tube 121. The cable enters the cable protection tube 121 through the large diameter end of the bell mouth, which facilitates the insertion of the cable and prevents the uneven end of the cable protection tube 121 from scratching the insulation layer of the cable.

[0038] Please refer to Figure 3 and Figure 4 In this embodiment, a mounting boss 131 is provided at one end of the drain pipe unit 100 along the third direction, and a mounting groove 132 is provided at the other end along the third direction. The mounting boss 131 is mated and plugged with the mounting groove 132 of the adjacent drain pipe unit 100. It is conceivable that, in order to improve installation efficiency, the size of the mounting groove 132 should be no smaller than that of the mounting boss 131, and a certain amount of installation and mating space should be reserved to reduce the difficulty of installation. The mating and plugging of the mounting boss 131 and the mounting groove 132 not only plays a positioning role, simplifies the positioning steps during installation, and improves installation efficiency, but also suppresses the relative displacement of the drain pipe units 100 connected along the third direction in the first direction, thereby improving the installation stability of the power drain pipe. Those skilled in the art can imagine that the installed drainage pipe body should be placed on a prefabricated cushion layer 200, which is made of cast concrete or paved with floor slabs. Its purpose is to improve the levelness of the installation ground to improve the stability during installation and reduce the hazards caused by ground subsidence, thereby further improving the durability of the power drainage pipe.

[0039] Optionally, a lifting ring is fixed to the outer wall of the pipe unit 100. The pipe unit 100 is made of lightweight concrete (i.e., concrete with a density of no more than 1800 kg / m3). While maintaining its load-bearing properties, the weight of each pipe unit 100 is reduced. The lifting ring allows for easy and convenient lifting of the pipe unit 100. For urban areas with limited operating space, this not only reduces construction costs but also minimizes the impact on the surrounding environment.

[0040] Please refer to Figure 5Furthermore, a connecting boss 111 is provided at one end of the drain pipe monomer 100 along the second direction, and a connecting groove 112 is provided at the other end along the second direction. Two adjacent drain pipe monomers 100 are plugged in and matched with the connecting boss 111 and the connecting groove 112. Similarly, the matching and plugging of the connecting groove 112 and the connecting boss 111 not only simplifies the positioning steps during installation and improves the installation efficiency, but also improves the installation stability of the power drain pipe. Preferably, a waterproof rubber strip is provided at the connection of the two drain pipe monomers 100 connected along the second direction, which is used to seal the connection gap between the two drain pipe monomers 100. The waterproof rubber strip is provided at the connection gap, and the waterproof rubber strip can swell when exposed to water, thereby improving the sealing performance and waterproof performance of the connection gap, preventing water from entering the inside of the power drain pipe and affecting the safe operation of the cable.

[0041] Optionally, two adjacent pipe array units 100 are fixedly connected by connecting bolts. It is conceivable that when using connecting bolts for connection, mounting holes should be opened on the pipe array units 100 to fix the connecting bolts in the mounting holes. The two pipe array units 100 connected along the first direction, the second direction or the third direction are fixed by connecting bolts. Not only is the connection method simple and efficient, but it also improves the stability of the installation and ensures the overall firmness of the installed pipe body. The power pipe is made by splicing a plurality of prefabricated pipe array units 100 side by side in different directions, freely combining to form different pipe cross sections, and assembling modularly. The connected pipe array units 100 are connected by pure dry bolts, and there is no welding operation on site, which reduces wet operations such as concrete pouring and improves the construction speed. In addition, the power pipe has the advantages of reasonable design, low cost, and simple installation, and has good economic benefits and application prospects.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
