Description

Technical Field

[0002] A pipeline system is a pipeline network used to transport various substances such as water, gas, electricity, sewage, etc. in a building or industry. The design and installation of these systems are to facilitate the transportation of materials and create the necessary infrastructure for construction and industry.

[0003] A pipeline system generally consists of three main parts: pipes, connectors, and devices. Among them, different pipes are used to transport different materials, and these pipes can be made of various materials such as PVC, steel, copper, polyethylene, etc.; various connectors are used to connect the pipes to each other and connect them to various devices connected to the pipeline system, and these connections can include nuts, valves, couplings, etc.; various devices such as water pumps, power take-off boxes, air conditioning systems, heating and air conditioning devices are also connected to the pipeline system.

[0005] The combined assembly of fire pipelines is an important link in its application process. The assembly of fire pipelines usually refers to fixedly connecting pipes and connectors in a certain order to make them have a transportation function. However, due to the special structure of the fire pipeline system, a series of problems often occur during the assembly and clamping process, including: 1. A single clamping method cannot adapt to the clamping and positioning of diverse pipes, connectors, and sensor modules. Specifically, there are significant differences in parameters such as shape and size among the pipes, connectors, and sensors in the fire pipeline system, and the clamping position needs to be selected according to the assembly method during the assembly and clamping process.

[0006] 2. Different pipes, connectors, and sensor modules have different assembly connection methods, and the clamping schemes adopted for different assembly methods are also different, greatly increasing the clamping difficulty. Specifically, some connectors are connected to the main pipeline by means of plug-in and clamping, while some sensor modules need to be connected to the main pipeline by means of screwing, and corresponding clamping mechanisms are required to cooperate with these assembly processes to achieve.

[0007] 3. The problem of inconvenient steering adjustment for the assembly connection of different ports of the main pipeline.
