Description

Technical Field

[0001] The present invention relates to the technical field of electrical quick-install pipelines, and specifically to a self-grounding method and pipeline for electrical quick-install pipelines in assembled buildings. Background Art

[0002] Electrical wiring is a core component of building electrical engineering, primarily used for the transmission and distribution of electrical energy. In prefabricated buildings, electrical wiring is constructed simultaneously with the building structure through prefabricated composite layer pipeline ducts and vertical shaft plug-in busbars. Traditional building electrical pipeline installation typically involves on-site welding, bolting, or gluing. This cumbersome and inefficient process makes it difficult to adapt to the rapid construction requirements of prefabricated buildings. Existing pipeline connection structures often rely on a single sealing or fixing method, such as rubber gaskets or bolts. These methods suffer from insufficient sealing and poor resistance to displacement, making them prone to loosening or leakage, especially in complex wiring scenarios. For later maintenance, traditional pipelines require complete disassembly to inspect the internal wiring harnesses, which is not only time-consuming and labor-intensive, but can also damage the original structure. Summary of the Invention

[0003] In order to solve the problem that the construction process is cumbersome and inefficient and difficult to adapt to the needs of rapid construction of prefabricated buildings, the present invention provides a self-grounding method and pipeline for prefabricated building electrical quick-install pipelines to solve the above problems.

[0004] To achieve the above object, the present invention provides the following technical solutions: A self-grounding method and pipeline for a prefabricated building electrical quick-install pipeline, comprising a first quick-install pipe and a second quick-install pipe, wherein the second quick-install pipe is equipped with a quick-connect assembly for auxiliary connection to the first quick-install pipe, wherein the first quick-install pipe and the second quick-install pipe are both connected to side connecting pipes at their rear ends, and the rear ends of the two side connecting pipes are both connected to an electrical main line; Wherein, side pipe connectors are provided between the adjacent electrical main pipes and side connecting pipes for support and fixation, and a circuit detection member for detecting the circuit is also slidably connected inside the second quick-connect pipe.

[0005] Furthermore, a groove connector is installed on the first quick-connect pipe, and the first quick-connect pipe is engaged with the quick-connect assembly on the second quick-connect pipe through the groove connector.

[0006] Furthermore, the quick-connect assembly includes a hinge shaft, a connecting joint is rotatably connected to the hinge shaft, a torsion spring is installed at the rotation connection portion between the hinge shaft and the connecting joint, and a pulling wing is installed on the connecting joint.

[0007] Furthermore, the pulling wing is connected to a pull ring for facilitating pulling the pulling wing.

[0008] Furthermore, the side connecting pipe includes a connecting pipe body, a positioning ring is installed on the connecting pipe body, and a sealing rubber tube is installed at one end of the connecting pipe body close to the first quick-connect pipe.

[0009] Furthermore, a rubber sealing ring is installed at one end of the connecting pipe body close to the main electrical line.

[0010] Furthermore, a vertically extending pipeline is installed on the main electrical pipeline.

[0011] Furthermore, the line detection component includes a sliding ring, a sliding block is installed on the sliding ring, the sliding ring is slidably connected to the inner wall of the first quick-connect pipe through the sliding block, and a plurality of magnetic blocks and cameras are installed on the sliding ring.

[0012] Furthermore, the side pipe connector includes a first connecting block and a second connecting block. The first connecting block is connected to the side connecting pipe, and the second connecting block is connected to the main electrical line. A connecting screw is rotatably connected to the first connecting block, and the other end of the connecting screw passes through and is threadedly connected to the second connecting block. A nut is threadedly connected to the connecting screw to fit and position the second connecting block.

[0013] A self-grounding method for electrical quick-install pipelines in prefabricated buildings, comprising the following steps: S1: Installation of electrical main pipes and side connecting pipes Insert the connecting pipe body of the side connecting pipe into the main electrical line, ensuring that the rubber sealing ring fits tightly. Push the main electrical line until its end contacts the positioning ring. Insert the connecting screw into the corresponding hole of the second connecting block and tighten the nut so that it fits tightly with the second connecting block to complete the initial fixation. Arrange the wires in the main electrical line and the vertical extension pipeline. If the direction of the vertical extension pipeline needs to be adjusted, first loosen the side pipeline connector, rotate the main electrical line to the required angle, and then retighten it.

[0014] S2: Connection between the side connecting pipe and the quick-connect pipe Insert the sealing rubber tube into the first quick-connect pipe or the second quick-connect pipe and use interference fit to achieve initial sealing. If you need to enhance stability, you can install additional side pipe connectors on the first and second quick-connect pipes to perform secondary fixation with the side connecting pipes.

[0015] S3: Quick connection between the first and second quick connectors Pull the pull ring to rotate the pulling wing and the connecting joint around the hinge axis, release the clamping state, insert the groove connector of the first quick-connect pipe into the second quick-connect pipe, loosen the pull ring, and the torsion spring automatically resets, so that the connecting joint is stuck in the groove of the groove connector, completing the quick locking.

[0016] S4: Use and adjustment of line detection components An external magnet attracts the magnetic block to push the line detector to move inside the first quick-connect pipe. The tilted camera is used to observe the internal wiring harness status, covering the first quick-connect pipe, the second quick-connect pipe, the side connecting pipe and the main electrical line. If the smoothness of movement needs to be improved, the sliding block can be replaced with a walking wheel structure. When the camera is damaged or needs to be repaired, the side connecting pipe on one side is removed and the line detector is taken out for maintenance or replacement.

[0017] S5: Overall inspection and optimization Check the sealing and tightness of all connection parts to ensure there is no looseness or leakage, test the mobility of the line detection parts and the camera clarity, adjust the angles of each pipeline according to actual needs, and optimize the wiring direction.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The synergy between this segmented quick-connect fitting and its connectors: The first and second quick-connect fittings utilize a spring-return clamping structure with a grooved connector and an articulated shaft, combined with a pull ring for quick assembly and disassembly. The side connecting pipes utilize a sealing rubber tube with an interference fit to form a basic seal with the quick-connect fittings. Optional side pipe connectors enhance securement, balancing installation speed and stability. The connection between the main electrical line and the side connecting pipes is secured by a rubber sealing ring and connecting screw. The threaded locking nut and second connecting block ensure airtightness and anti-displacement capabilities. The rotatable design of the vertical extension pipe allows for highly flexible wiring layout. The overall structure, utilizing standardized components, achieves multi-directional extension, meeting complex wiring requirements while significantly shortening construction cycles.

[0019] 2. The innovative integrated line detection components of the device significantly optimize the post-maintenance experience. The aluminum sliding ring and magnetic block cooperate with the external magnet to realize the non-disassembly movement of the detection module in the pipeline. The tilted camera can fully monitor the internal wiring harness status of each section of the pipeline, effectively preventing potential faults. In terms of material selection, the lightweight and corrosion-resistant properties of aluminum reduce the system's own weight and operation and maintenance costs, and the design that the sliding block can be replaced with a walking wheel further enhances the smoothness of detection. In addition, the modular design supports rapid maintenance: wearing parts such as the camera only need to disassemble the single-side side connecting pipe to be replaced, avoiding the waste of work time caused by disassembly of the entire pipeline. This design organically combines assembly efficiency, structural stability and intelligent detection functions, providing a highly adaptable solution for prefabricated building electrical systems.

[0023] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] Reference Figure 1-5 A prefabricated building electrical quick-install pipeline includes a first quick-install pipe 1 and a second quick-install pipe 2. The second quick-install pipe 2 is equipped with a quick-install assembly 3 for auxiliary connection to the first quick-install pipe 1. The first quick-install pipe 1 and the second quick-install pipe 2 are both connected to side connecting pipes 4 at their rear ends. The rear ends of the two side connecting pipes 4 are both connected to an electrical main line 5. Among them, side pipe connectors 7 are provided between adjacent electrical main pipes 5 and side connecting pipes 4 for support and fixation, and a line detection member 6 for detecting the line is also slidably connected inside the second quick-connect pipe 2 .

[0025] In this embodiment, a groove connector 11 is installed on the first quick-connect pipe 1, and the first quick-connect pipe 1 is engaged with the quick-connect assembly 3 on the second quick-connect pipe 2 through the groove connector 11. A vertical extension pipe 51 is installed on the main electrical pipe 5.

[0026] To connect the first quick-connect pipe 1 and the second quick-connect pipe 2, first insert the groove connector 11 on the first quick-connect pipe 1 into the second quick-connect pipe 2, first pull the pull ring 32 to drive the pulling wing 31 and the connecting joint 33 to rotate on the hinge shaft 34, then insert the groove connector 11 and release the pull ring 32. At this time, the torsion spring between the connecting joint 33 and the hinge shaft 34 will reset the pulling wing 31 and the connecting joint 33. The connection joint 33 cooperates with the groove on the groove connector 11 to achieve a quick clamping effect, which is convenient and quick to operate. In this embodiment, the quick-connect assembly 3 includes a hinge shaft 34, which is rotatably connected to a connecting joint 33. The rotating connection portion between the hinge shaft 34 and the connecting joint 33 is provided with a torsion spring. A pulling wing 31 is installed on the connecting joint 33, and a pull ring 32 is connected to the pulling wing 31 for facilitating pulling the pulling wing 31.

[0027] In this embodiment, the side connecting pipe 4 includes a connecting pipe body 43, a positioning ring 41 is installed on the connecting pipe body 43, a sealing rubber tube 42 is installed on the end of the connecting pipe body 43 close to the first quick-connect pipe 1, and a rubber sealing ring 44 is installed on the end of the connecting pipe body 43 close to the electrical main line 5.

[0028] The connection between the side connecting pipe 4 and the first quick-connect pipe 1 and the second quick-connect pipe 2 is directly connected by a sealing rubber tube 42 inserted into the first quick-connect pipe 1 or the second quick-connect pipe 2, and the sealing rubber tube 42 and the inner wall of the first quick-connect pipe 1 and the second quick-connect pipe 2 are squeezed by interference fit. If you feel that this is unstable, you can add a set of side pipe connectors 7 to each of the first quick-connect pipe 1 and the second quick-connect pipe 2, and connect them to the two side connecting pipes 4 respectively to achieve secondary fixation. Although the loading and unloading speed is slowed down, the stability is better. In this embodiment, the line detection member 6 includes a sliding ring 61, on which a sliding block 62 is installed. The sliding ring 61 is slidably connected to the inner wall of the first quick-connect pipe 1 through the sliding block 62, and a plurality of magnetic blocks 63 and a camera 64 are installed on the sliding ring 61.

[0029] In this embodiment, the side pipe connector 7 includes a first connecting block 71 and a second connecting block 74. The first connecting block 71 is connected to the side connecting pipe 4, and the second connecting block 74 is connected to the electrical main line 5. A connecting screw 72 is rotatably connected to the first connecting block 71, and the other end of the connecting screw 72 passes through and is threadedly connected to the second connecting block 74. A nut 73 is threadedly connected to the connecting screw 72 to fit and position the second connecting block 74.

[0030] The two side connecting pipes 4 are respectively connected to the electrical main line 5. The connection between the electrical main line 5 and the side connecting pipe 4 is to first insert the connecting pipe body 43 into the electrical main line 5, and then use the rubber sealing ring 44 to seal the connection between the electrical main line 5 and the side connecting pipe 4, and keep the electrical main line 5 and the positioning ring 41 in position. During this process, the connecting screw 72 will be inserted into the corresponding second connecting block 74. At this time, it is only necessary to thread the nut 73 and the connecting screw 72 until it is tightly fitted with the second connecting block 74 to achieve a positioning effect. At this time, the electrical main line 5 and the vertical extension pipeline 51 can place wires as needed. When the direction of the vertical extension pipeline 51 needs to be adjusted, it is necessary to release the side pipeline connector 7 and then rotate the electrical main line 5 to adjust the direction of the vertical extension pipeline 51.

[0031] Working Principle: The device is divided into six sections. The second quick-connect pipe 2 and the first quick-connect pipe 1 are connected in the center. The second quick-connect pipe 2 and the first quick-connect pipe 1 each extend a side connecting pipe 4. Finally, the second quick-connect pipe 2 and the first quick-connect pipe 1 are each allocated an electrical main line 5 through two side connecting pipes 4, thereby achieving a better connection effect. When the device is in use, first connect the two side connecting pipes 4 to the main electrical line 5 respectively. To connect the main electrical line 5 to the side connecting pipe 4, first insert the connecting pipe body 43 into the main electrical line 5, and then use the rubber sealing ring 44 to seal the connection between the main electrical line 5 and the side connecting pipe 4. Keep the main electrical line 5 and the positioning ring 41 in place. During this process, the connecting screw 72 will be inserted into the corresponding second connecting block 74. At this time, it is only necessary to thread the nut 73 and the connecting screw 72 until they are tightly fitted with the second connecting block 74 to achieve a positioning effect. At this time, wires can be placed on the main electrical line 5 and the vertical extension pipeline 51 as needed. When the direction of the vertical extension pipeline 51 needs to be adjusted, it is necessary to release the side pipeline connector 7 and then rotate the main electrical line 5 to adjust the direction of the vertical extension pipeline 51. The connection between the side connecting pipe 4 and the first quick-connect pipe 1 and the second quick-connect pipe 2 is then directly made by inserting a sealing rubber tube 42 into the first quick-connect pipe 1 or the second quick-connect pipe 2. The sealing rubber tube 42 and the inner wall of the first quick-connect pipe 1 and the second quick-connect pipe 2 are squeezed with an interference fit. If this is considered unstable, a set of side pipe connectors 7 can be added to each of the first quick-connect pipe 1 and the second quick-connect pipe 2, and connected to the two side connecting pipes 4 respectively, to achieve secondary fixation. Although the loading and unloading speed is slowed down, the stability is better. Finally, to connect the first quick-connect pipe 1 and the second quick-connect pipe 2, first insert the groove connector 11 on the first quick-connect pipe 1 into the second quick-connect pipe 2, first pull the pull ring 32 to drive the pulling wing 31 and the connecting joint 33 to rotate on the hinge shaft 34, then insert the groove connector 11 and release the pull ring 32. At this time, the torsion spring between the connecting joint 33 and the hinge shaft 34 will reset the pulling wing 31 and the connecting joint 33. The connection joint 33 cooperates with the groove on the groove connector 11 to achieve a quick clamping effect, which is convenient and quick to operate. The existence of the line detection part 6 allows the camera 64 to observe the wiring harness inside the first quick-connect pipe 1 without disassembling the entire main body. The camera 64 is set at an angle, and can basically observe the entire first quick-connect pipe 1, the second quick-connect pipe 2, the side connecting pipe 4, and the electrical main line 5; Furthermore, the entire first quick-connect pipe 1, the second quick-connect pipe 2, the side connecting pipe 4, the main electrical line 5, and the sliding ring 61 are all made of aluminum. In this case, with the presence of the magnetic block 63, a magnet can be used from the outside of the first quick-connect pipe 1 to attract the magnetic block 63, and the magnet can be pulled to move the line detection member 6 within the first quick-connect pipe 1. If it is necessary to make the line detection member 6 move more smoothly, the sliding block 62 can be replaced with a running wheel. In addition, when the camera 64 is damaged or needs to be repaired, the line detection member 6 can be removed by removing the side connecting pipe 4 on one side of the first quick-connect pipe 1.
