Description

Technical Field

[0001] This utility model relates to the field of power pipes, specifically a connection structure for BWFRP power pipes. Background Technology

[0002] BWFRP (glass fiber reinforced plastic) power conduits are used in electrical engineering to protect power cables. BWFRP is characterized by its excellent corrosion resistance, compressive strength, tensile strength, and insulation properties. Widely used for protecting underground power cables, BWFRP conduits are suitable for harsh environments such as high humidity and chemical corrosion. These conduits are lightweight, durable, and easy to install, significantly improving the safety and lifespan of power systems. Furthermore, BWFRP power conduits offer high electrical insulation, ensuring the stability of electrical equipment.

[0003] Chinese patent CN221947809 U discloses a connection structure for an MPP power pipe. By setting a connecting block and a retainer, the retainer is provided with a U-shaped groove and a locking groove, and a locking block is connected to the connecting block by an elastic component. This allows the connecting block to be engaged in the U-shaped groove, and under the action of the elastic component, the locking block on the connecting block is engaged in the locking groove, thereby realizing the connection and fixation between the power pipe and the connector.

[0004] However, the above structure requires a large number of power pipes in actual installation. The splicing of multiple sets of power pipes is quite cumbersome for workers. At the same time, disassembly is also cumbersome when maintaining and inspecting the internal cable assemblies. In order to ensure the sealing between the power pipes, sealing gaskets are usually installed at the connection points of the power pipes. When the power pipes are disassembled for inspection and maintenance of the cable assemblies, the overall sealing effect of the sealing gaskets will be greatly reduced, affecting the overall service life. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a connection structure for BWFRP power pipes to solve the technical problem that the splicing and subsequent disassembly of multiple power pipes is cumbersome for workers, and that the disassembly of power pipes during subsequent inspection and maintenance of cable assemblies will greatly reduce the overall sealing effect of the sealing gasket and affect the overall service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a BWFRP power conduit, comprising a conduit body, a plug at one end of the conduit body, and a socket at the other end of the conduit body. A slider is symmetrically arranged on the plug, and a groove for sliding the slider is formed within the socket. A rotating groove is formed at the other end of the groove within the socket. An elastic air cushion is installed within the rotating groove, and a sealing air cushion is provided on the inner wall of the socket. The sealing air cushion and the elastic air cushion are interconnected and equipped with a valve. A limiting mechanism that cooperates with the slider is provided on the outer wall of the conduit body.

[0007] By adopting the above technical solution, the rotating groove will limit the slider in the vertical direction, and at the same time, the limiting pin will limit it in the horizontal direction, thereby further accelerating the overall splicing of the tube. During the process of the slider sliding in and rotating, the plug will squeeze the elastic air cushion on one side. At this time, during the tube splicing process, the sealing air cushion ensures the sealing of the connection between them. During subsequent disassembly, the gas in the sealing air cushion flows back into the elastic air bladder, releasing the contact between it and the plug. This process ensures that the sealing air cushion can be used for disassembly and reassembly of the tube multiple times.

[0008] The present invention is further configured such that the limiting mechanism includes a through hole and a limiting pin, the outer wall of the tube body is provided with a through hole at the insertion hole, and the limiting pin is slidably provided in the through hole, and the top of the slider is provided with a pin hole that cooperates with the limiting pin.

[0009] Preferably, during the rotation of the slider following the tube, the pin hole at its top will be in the same vertical direction as the through hole. At this time, the operator can push the limiting pin downward to insert one end of the limiting pin into the pin hole, thereby limiting the slider to work inside the rotating groove. At the same time, the operator can directly disassemble the tube by pulling out the limiting pin, which effectively improves the overall practicality of the device.

[0010] The present invention is further configured such that one end of the limiting pin is arc-shaped, and a rough surface is provided between the outer wall of the limiting pin and the through hole.

[0011] Preferably, the arc shape facilitates stable insertion into the pin hole during sliding, and the rough surface increases the sliding friction between the limiting pin and the through hole, preventing the limiting pin from easily sliding on the tube body, and further improving the stability of the connection between the tube bodies.

[0012] The present invention is further configured such that an array of reinforcing ribs are provided on the outer wall of the tube, and the reinforcing ribs are arranged in a circumferential manner on the outer wall of the tube.

[0013] Preferably, the reinforcing ribs ensure the compressive strength of the tube itself, and the circumferential design further ensures that the tube will not dent, thus improving the overall service life of the device.

[0014] The present invention is further configured such that the top of the pin hole is open and a rough surface is provided inside it.

[0015] Preferably, the open design allows for the engagement of the top limiting pin, which acts as a guide, and the rough surface further prevents the limiting pin from disengaging from the slider, thus improving the stability of the slider within the rotating groove.

[0016] The present invention is further configured such that the sealing gasket itself is composed of multiple layers of materials, and the inner wall of the insertion hole is detachably configured.

[0017] Preferably, the sealing gasket made of multiple layers of materials can effectively prevent wear and tear, ensure that the sealing gasket can make full contact with the outer wall of the plug, extend the overall service life of the sealing gasket, and the detachable design makes it easy for staff to replace and maintain it.

[0018] The present invention is further configured such that one end of both the plug and the socket is provided with an arc-shaped end face, and the arc-shaped end face is provided in a smooth manner.

[0019] Preferably, when the plug is inserted into the socket at one end, the smooth design reduces the sliding friction between the two, effectively preventing the plug from getting stuck during insertion.

[0020] The present invention is further configured such that the thickness of the tube gradually increases from the inside to the outside.

[0021] Preferably, during the transportation of the power pipe, the pipe body is prevented from bending due to compression, which facilitates the simultaneous transportation of multiple sets of pipes by the staff.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model has a sliding groove and a rotating groove in the socket. The operator slides the slider on the plug into the sliding groove of the other end of the socket and then rotates the tube. At this time, the rotating groove will limit the slider in the vertical direction, and at the same time, the limiting pin will limit it in the horizontal direction. This further speeds up the overall splicing of the tube. When the operator inspects and maintains the internal cable assembly, it saves a lot of manpower and resources.

[0024] 2. This utility model incorporates an elastic air cushion within the rotating groove. As the slider slides in and rotates, the plug compresses one side of the elastic air cushion, thereby discharging the gas within the elastic air cushion into the sealing air cushion. During the assembly of the tubes, the sealing air cushion ensures the airtightness of the connection. Upon subsequent disassembly, the gas within the sealing air cushion flows back into the elastic air bladder, releasing the contact with the plug. This process ensures that the sealing air cushion can be used in conjunction with the tubes for multiple disassemblies, guaranteeing overall sealing and extending the overall service life.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] First embodiment:

[0035] Please see Figures 1-5The diagram illustrates a connection structure for a BWFRP power conduit, comprising a conduit body 1, a plug 7, a socket 3, a sealing mechanism, a sliding mechanism, and a limiting mechanism. The plug 7 is symmetrically equipped with sliders 6, and a groove 10 is provided within the socket 3 for the sliders 6 to slide. Workers insert the plug 7 at one end of the conduit body 1 into the socket 3 of another conduit body 1. The slider 6 slides within the socket 3 aligned with the groove 10. Since the other end of the groove 10 is located within the socket 3, a rotating groove 11 is provided. When the slider 6 slides into the rotating groove 11, the worker rotates the entire conduit body 1, causing the slider 6 to rotate within the rotating groove 11. The rotating groove 11 limits the slider 6 vertically. When the slider 6 rotates to the through hole 5, a limiting pin 9 fixes the slider 6 within the rotating groove 11, thus limiting its horizontal movement. This further accelerates the overall assembly of the conduit body, saving significant manpower and resources for subsequent inspection and maintenance of the internal cable assemblies.

[0036] Furthermore, an elastic air cushion 12 is installed inside the rotating groove 11, and a sealing air cushion 4 is provided on the inner wall of the insertion hole 3. The sealing air cushion 4 and the elastic air cushion 12 are interconnected and equipped with a valve. When the tube body 1 drives the plug 7 to slide in the insertion hole 3, it will compress the elastic air cushion 12 in the insertion hole 3. During this process, the elastic air cushion 12 deforms and discharges the gas inside it into the sealing air cushion 4. At this time, during the splicing of the tube body 1, the sealing air cushion 4 contacts one end of the plug 7, ensuring the sealing of the connection between the tube bodies 1. At the same time, when it is disassembled later, the plug 7 will release the compression of the elastic air cushion 12. At this time, the gas inside the sealing air cushion 4 is drawn back by the reset action of the elastic air cushion 12, thereby releasing the contact between it and the plug 7. In this process, the sealing air cushion 4 can be used in conjunction with the tube body 1 for disassembly and reassembly multiple times, ensuring the overall seal and extending the overall service life.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The tube body 1 has an array of reinforcing ribs 2 on its outer wall, and the reinforcing ribs 2 are arranged in a circumferential manner on the outer wall of the tube body 1. The reinforcing ribs 2 ensure the tube body's compressive strength, and the circumferential arrangement further ensures that the tube body 1 will not dent, thus improving the overall service life of the device.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Furthermore, the sealing gasket 4 itself is composed of multiple layers of materials, and the inner wall of the socket 3 is detachable. The multi-layered sealing gasket 4 can effectively prevent wear and tear, ensuring that the sealing gasket 4 can make full contact with the outer wall of the plug 7, thus extending the overall service life of the sealing gasket 4. The detachable design also makes it convenient for staff to replace and maintain it.

[0039] Second embodiment:

[0040] Please see Figure 3 The connection structure of the BWFRP power pipe shown is similar to that of Embodiment 1. A through hole 5 is provided through the outer wall of the pipe body 1 at the insertion hole 3, and a limit pin 9 is slidably provided in the through hole 5. The top of the slider 6 is provided with a pin hole 8 that cooperates with the limit pin 9. When the slider 6 rotates with the pipe body 1, the pin hole 8 at its top will be in the same vertical direction as the through hole 5. At this time, the operator can push the limit pin 9 downward to insert one end of the limit pin 9 into the pin hole 8, thereby limiting the slider 6 to work inside the rotating groove 11. At the same time, the operator can directly disassemble and reassemble the pipe body 1 by pulling out the limit pin 9, which effectively improves the overall practicality of the device.

[0041] In practical operation, this invention works as follows: When in use, the plug 7 at one end of tube 1 is inserted into the insertion hole 3 inside another set of tubes 1. At this time, the slider 6 on the plug 7 slides through the groove 10 inside the insertion hole 3. When the slider 6 on the plug 7 slides to the rotating groove 11, the tube 1 is rotated to vertically limit the slider 6. Simultaneously, the limiting pin 9 acts to horizontally limit it, thereby further accelerating the overall splicing of tubes 1. During the insertion of the plug 7, the elastic air cushion 12 inside the rotating groove 11 is compressed. Because the elastic air cushion 12 and the seal... Valves connect the air cushions 4, allowing the gas inside the elastic air cushion 12 to be discharged into the sealing air cushion 4. This ensures that during the splicing of the tubes, the sealing air cushion 4 makes full contact with the outer wall of the plug 7, guaranteeing the sealing between the tubes 1. Furthermore, during subsequent disassembly, the plug 7 releases its pressure on the elastic air cushion 12, and the sealing air cushion 4 releases its contact with the plug 7 through its own reset action. This process facilitates the direct disassembly of the tubes 1 by the operator, and the sealing air cushion 4 will not be worn due to the slippage of the internal cable, thus extending the overall service life of the sealing air cushion 4.
