Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and in particular to a high-voltage power pipe connection structure for power transmission. Background Technology

[0002] As a crucial component of urban infrastructure, power pipelines are widely used for cable laying and protection, and their operational reliability directly impacts the safety and stability of the power system. However, in existing projects, power pipeline connection structures often employ rigid sleeves or flanges. While these achieve basic connection and fixation, they require strict alignment and complex adjustments during construction, resulting in low installation efficiency. Furthermore, after burial, power pipelines are susceptible to ground settlement and environmental changes; rigid connections are prone to stress concentration, leading to pipe cracks or even damage, thus affecting cable operational stability. In addition, existing sealing structures are mostly single-design; once the seal fails, mud, water, and dirt can easily seep into the pipeline, causing cable damage and shortening its lifespan. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-voltage power pipe connection structure for power transmission.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-voltage power pipe connection structure for power transmission includes a power pipe and two inner rings arranged symmetrically. The two inner rings are connected by a pipe. The cross-section of the two inner rings at the ends that are far apart is designed in a wedge shape. The outer rings at the ends that are far apart are fixedly connected to an outer ring by bolts. The cross-section of the outer ring is adapted to the cross-section of the inner ring.

[0005] Preferably, the two inner rings are flexibly connected by a bellows.

[0006] Preferably, a sealing gasket is glued to the surface of the outer ring that contacts the power pipe, and a sealing gasket is glued to the surface of the inner ring that contacts the power pipe.

[0007] Preferably, a cavity is provided between the corrugated pipe and the two power pipes. An inductor is fixedly installed inside the cavity. The sealing gasket two has a copper ring one and a copper ring two sleeved on the outside of the power pipe on the side near the inductor. The left and right ends of the inductor are provided with positive and negative terminals. The positive terminal is connected to the corresponding copper ring one through a cable, and the negative terminal is connected to the corresponding copper ring two through a cable. A relay is installed on the cable used for the negative terminal connection.

[0008] Preferably, a sleeve is provided on the outer side of both the outer ring and the inner ring, and the sleeve is used to protect the outer ring and the inner ring.

[0009] Compared with the prior art, the advantages of this utility model are: 1. During installation, the outer ring and inner ring are tightened with bolts to form a wedge-shaped clamping effect, which is simple to operate and does not require complicated on-site adjustments, thus saving installation time. At the same time, sealing gaskets 1 and 2 are set between the outer ring and the inner ring, which can effectively prevent water and dirt from entering during the compression process, ensuring that the power pipe and cable can maintain a stable and reliable operating environment after burial and extending the overall service life.

[0010] 2. This utility model adopts a corrugated pipe flexible connection design, which enables the power pipe to move accordingly with the foundation changes, avoiding pipe damage caused by rigid connection. Under the condition of slight displacement due to foundation settlement, the cable and power pipe can still maintain a safe operating state, effectively improving the system's adaptability to complex geological conditions, reducing the operational risks caused by foundation changes, and further improving the reliability and durability of power facilities.

[0011] 3. Under the monitoring circuit formed by the copper ring and the relay, this utility model can realize circuit conduction and trigger the relay to act when the sealing gasket fails and mud and water seeps in. It can also issue an alarm prompt through the I / O module. This design can quickly warn of potential hazards in the early stage, help staff to deal with them in time, avoid the escalation of accidents, and the fixed-point alarm mechanism can greatly reduce the scope and time of investigation, improve maintenance efficiency, and ensure the safety and stability of cable operation.

[0012] In summary, this utility model achieves convenient installation and efficient sealing through structural optimization, enhances the device's adaptability to foundation changes through flexible connections, and provides water seepage alarm through intelligent detection, forming a triple protection of structure, environment, and monitoring. This design not only extends the service life of power pipes and cables but also significantly improves the safety and maintenance efficiency of power system operation. Attached Figure Description

[0017] 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.

[0018] Reference Figures 1 to 3 A high-voltage power pipe connection structure for power transmission includes two symmetrically arranged inner rings 5, which are flexibly connected by a corrugated pipe 6. The corrugated pipe 6 design allows the power pipe 1 to move with the foundation, preventing damage to the power pipe 1 caused by rigid connection during foundation changes, which would affect the normal operation and lifespan of the cable. The cross-section of the two inner rings 5 ​​at the far end is wedge-shaped, and an outer ring 4 is fixedly connected to the outer side of the far end of each inner ring 5 by bolts 3. The cross-section of the outer ring 4 is adapted to the cross-section of the inner ring 5 and is also wedge-shaped, so that the two fit tightly together during installation.

[0019] A sealing gasket 1 8 is glued to the surface of the outer ring 4 that contacts the power pipe 1, and a sealing gasket 2 9 is glued to the surface of the inner ring 5 that contacts the power pipe 1. The sealing gasket 1 8 on the outer ring 4 provides the first line of protection against water and dirt, while the sealing gasket 2 9 on the inner ring 5 can basically prevent water and dirt from entering, ensuring the normal operation and service life of the cable.

[0020] A cavity is provided between the corrugated pipe 6 and the two power pipes 1. An inductor 7 is fixedly installed inside the cavity. A copper ring 11 and a copper ring 2 12, fitted onto the outside of the power pipe 1, are located on the side of the sealing gasket 2 9 near the inductor 7. Both ends of the inductor 7 have positive and negative terminals. The positive terminal is connected to the corresponding copper ring 11 via a cable, and the negative terminal is connected to the corresponding copper ring 2 12 via a cable. A relay 10 is installed on the cable used for the negative terminal connection. When the sealing gasket 1 8 and sealing gasket 2 9 fail, causing mud and water to seep in and reach between copper ring 11 and copper ring 2 12, the circuit is completed, causing the relay 10 to activate. The relay 10 contacts are connected to the I / O module, which then issues an alarm to prompt personnel to handle the situation. This targeted alarm reduces troubleshooting time.

[0021] The outer ring 4 and the inner ring 5 are both fitted with a sleeve 2, which serves to protect the outer ring 4 and the inner ring 5.

[0022] In this utility model, after the power pipe 1 passes through the outer ring 4 and the inner ring 5, the installer is responsible for tightening the bolts 3 and then using the outer sleeve 2 for protection before burying. This is convenient and quick, eliminating the need for on-site alignment adjustment required for rigid connections, saving installation time, and reducing the release of harmful stress caused by rigid connections after burying. At the same time, it improves the service life of the connection mechanism and the power pipe 1. By tightening the bolts 3, the outer ring 4 and the inner ring 5 are squeezed by the wedge surface, causing the inner ring 5 to hold the power pipe 1 tightly. The outer ring 4 has a sealing gasket 8 on its outer side for the first line of protection against water, dirt, etc. The inner ring 5 and the power pipe 1 have a sealing gasket 9 between them. With the tightening of the inner ring 5, the seal is ensured to basically prevent the entry of water, dirt, etc., ensuring the normal operation and service life of the cable.

[0023] The flexible connection via the corrugated pipe 6 allows the power pipe 1 to move with the foundation, preventing damage to the power pipe 1 caused by rigid connection during foundation changes, which would affect the normal operation and lifespan of the cable. The inductor 7 is connected to the circuit via a cable, with its positive and negative terminals connected to copper ring 11 and copper ring 12, respectively. When the sealing gasket 8 and sealing gasket 9 fail, causing mud and water to seep in and reach between copper ring 11 and copper ring 12, the circuit will be connected, causing the relay 10 to engage. The contacts of the relay 10 are connected to the I / O module, and the I / O module will issue an alarm to prompt personnel to handle the situation. The fixed-point alarm reduces troubleshooting time.

[0024] 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.
