Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction and maintenance technology, specifically a water conservancy pipeline connection device. Background Technology

[0002] In the construction of water conservancy projects, the preliminary planning stage requires comprehensive and in-depth consideration of numerous complex factors. From a geographical perspective, a detailed geological survey of the project site is indispensable. This involves using advanced drilling technology to analyze the stratigraphic structure, accurately determine the soil bearing capacity, and meticulously investigate potential geological hazards. For example, when planning reservoir construction in mountainous areas, it is crucial to prioritize mountain stability assessments and rigorously detect the presence of faults and landslide hazards, thus providing a solid basis for building a stable foundation for key structures such as dams. Simultaneously, research on hydrological conditions is equally important, requiring long-term monitoring of river flow patterns, seasonal fluctuations in water levels, and other factors. Key indicators such as sediment content will directly guide critical decisions such as reservoir capacity design, flood discharge facility planning, and water conveyance line layout. For example, the reasonable size of the flood discharge channel can be scientifically determined based on the peak flow during the flood season to ensure effective flood discharge and project safety during floods. In addition, meteorological factors cannot be ignored. Comprehensive collection of local precipitation distribution characteristics, wind direction and force trends, and temperature fluctuation range meteorological data can help engineering designers optimize the overall project layout and effectively avoid the adverse effects of extreme weather on the construction process. For example, in areas with frequent strong winds, the orientation of buildings can be reasonably adjusted to reduce the risk of wind load damage to the project structure.

[0003] Throughout the construction and maintenance of water conservancy projects, pipeline connection is a frequent and highly challenging critical step. Traditional pipeline connection methods rely excessively on simple hangers, ropes, and crude clamps. These tools are limited in function, rudimentary, and have numerous drawbacks. Simple hangers can only provide basic support and cannot accurately position the pipeline radially and axially. In the complex environment of the construction site, even slight water flow impacts or collisions during construction operations can easily cause the pipeline to shake violently, making it impossible to effectively guarantee connection accuracy. This not only severely slows down the project progress but also greatly increases the risk of subsequent pipeline operation problems, such as leaks at the pipe joints and damage due to uneven stress. Moreover, traditional connection tools are limited in surface... For pipes of different diameters, there is a lack of necessary versatility. Each time the pipe specifications are changed, tools need to be reassembled and adjusted, which consumes a lot of time, manpower and resources. The sealing performance of pipe joints is one of the key factors to ensure the safe operation of water conservancy projects. However, the sealing methods of traditional connection methods are relatively simple, and leakage problems often occur due to poor sealing. This not only wastes precious water resources, but long-term leakage may also cause serious secondary disasters such as foundation subsidence. In addition, in the operation of water conservancy projects, it is crucial to accurately control the flow according to actual needs. However, traditional pipe connection methods lack effective flow regulation devices and are difficult to adapt to the complex and ever-changing operating conditions of water conservancy systems. As a result, the overall operating efficiency of water conservancy systems is limited, reliability is reduced, and the benefits of water conservancy projects cannot be fully realized.

[0004] However, existing technologies have the following problems in practical use:

[0005] When using the entire device, it is impossible to accurately position the pipeline radially and axially. During the connection process, the pipeline is prone to shaking due to water flow impact, installation operations, and other factors, making it difficult to guarantee the connection accuracy. This not only reduces the efficiency of pipeline connection but also greatly increases the risk of subsequent leaks, pipeline damage, and other failures. It is difficult to adapt to pipelines of different diameters, has poor versatility, and requires readjustment or replacement of auxiliary tools every time the pipeline specification is changed, which is time-consuming and labor-intensive. It does not adequately guarantee the sealing of pipeline connections and lacks effective adjustment devices, failing to meet the complex and ever-changing flow control needs of water conservancy systems, seriously affecting the overall operational reliability and stability of water conservancy systems.

This not only reduces the efficiency of pipeline connection but also greatly increases the risk of subsequent leaks, pipeline damage, and other failures. It is difficult to adapt to pipelines of different diameters, has poor versatility, and requires readjustment or replacement of auxiliary tools every time the pipeline specification is changed, which is time-consuming and labor-intensive. It does not adequately guarantee the sealing of pipeline connections and lacks effective adjustment devices, failing to meet the complex and ever-changing flow control needs of water conservancy systems.
