[0002] Pipeline is a kind of facility for conveying fluid (including liquid, gas or slurry), widely used in industry, municipal, construction and agriculture and multiple fields. Its basic structure is usually composed of pipeline body, pipe fitting, valve and accessory, and material is various, including metal (such as steel, cast iron, copper, etc.), plastic (such as PVC, PE, etc.), concrete and composite material, to adapt to different fluid characteristics and use environment. Through reasonable layout and design, pipeline system can effectively realize long-distance, large, continuous conveying of fluid, with high conveying efficiency, low energy consumption, stable operation and other advantages.
[0003] In building construction, fire protection pipeline and other types of pipeline are usually installed below floor through professional pipeline tooling technology. During installation, different degrees of leakage may occur at each connecting part of these pipelines due to improper installation or material aging. When the leakage is relatively slight, it is difficult for workers to discover these problems in time because it is not easy to detect. However, with the passage of time, even a small leakage may gradually intensify, eventually leading to corrosion at the pipeline connection. This corrosion not only weakens the structural strength of the pipeline, but also may further expand the leakage range, thereby threatening the safety of the entire building. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0020] The technical scheme in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.
[0021] As Figure 1 And Figure 2 The utility model provides pipeline laying tool's technical scheme convenient to assemble, including pipeline body 1, pipeline body 1 between being equipped with pipeline connector 4, pipeline body 1 outside is equipped with U-shaped frame body 3, U-shaped frame body 3 upper end is equipped with installation screw thread 2, and the connecting place of pipeline body 1 is equipped with pipeline tool 5, and lower tool seat 501 bottom is equipped with alarm mechanism 6, through pipeline tool 5 can quickly install pipeline body 1 in the floor below, and alarm mechanism 6 can detect leakage point, and remind user to handle leakage point in time.
[0022] As Figure 2 And Figure 3 Indicated, pipeline tool 5 includes the lower tool seat 501 connected on U-shaped frame body 3, and the upper tool seat 504 is equipped above lower tool seat 501, and the connector recess 506 is set up on lower tool seat 501 and upper tool seat 504, and the connector recess 506 both sides are equipped with sealing gasket 505, and the screw fastening ring 503 is equipped between upper tool seat 501 and lower tool seat 504, and the sealing strip is equipped between upper tool seat 501 and lower tool seat 504, and upper tool seat 501 and lower tool seat 504 keep sealing through sealing strip.
[0023] Specifically, after the lower tool holder 501 is installed inside the U-shaped frame body 3, the connection work of the pipeline body 1 can be carried out. The specific operation is to connect the pipeline body 1 to the inside of the lower tool holder 501, and ensure that the pipeline connector 4 on the pipeline body 1 is accurately seated in the connector groove 506. After this step is completed, the next work is to firmly fix the U-shaped frame body 3 on the floor. In this way, the pipeline body 1 can be quickly and efficiently installed below the floor, thereby achieving the expected installation effect.
[0024] As shown in Figure 2 and Figure 4 , the alarm mechanism 6 includes a detection sleeve 601 fixedly installed in the detection port 502, a buzzer 609 threadedly installed at the bottom of the detection sleeve 601, a power supply pin 608 fixedly installed on the buzzer 609, an elastic metal sheet 607 fixedly installed on the side wall of the detection sleeve 601, and an external power supply line connected to the elastic metal sheet 607, a water leakage plate 602 fixedly installed at the upper end of the detection sleeve 601, a water-permeable paper sheet 603 provided at the bottom of the water leakage plate 602, a piston 605 movably installed below the water-permeable paper sheet 603, bentonite 604 filled between the piston 605 and the water-permeable paper sheet 603, a supporting spring 606 provided below the piston 605, and a mounting groove provided on the detection sleeve 601, the elastic metal sheet 607 being installed in the detection sleeve 601 through the mounting groove, and the elastic metal sheet 607 being vertically aligned with the power supply pin 608.
[0025] Specifically, when leakage occurs at the connection of the pipeline body 1, the water leaking from the connection part will gather at the bottom of the connector groove 506. Over time, the water collected at the bottom of the groove will gradually increase, and eventually penetrate the water leakage plate 602 and come into contact with the bentonite 604 below. Once the water comes into contact with the bentonite 604, the bentonite 604 will rapidly expand due to water absorption. As the volume of the bentonite 604 increases, it will exert pressure on the piston 605, causing the piston 605 to move downward. The downward movement of the piston 605 will drive the elastic metal sheet 607 to press tightly against the power supply pin 608. When the elastic metal sheet 607 is in close contact with the power supply pin 608, the circuit of the buzzer 609 will be connected. Once the circuit of the buzzer 609 is connected, it will emit a loud alert sound, which serves as a signal to detect and indicate that leakage has occurred at the connection of the pipeline. The presence of this alert sound is to timely remind the user to pay attention and take measures to repair and handle the discovered leakage point to prevent further damage.
[0026] Working principle: when using, firstly install the lower tool seat 501 in the U-shaped frame body 3, after installing the lower tool seat 501 in the U-shaped frame body 3, the pipeline can be connected in the lower tool seat 501, and the pipeline connector 4 on the pipeline body 1 is located in the connector groove 506, then the U-shaped frame body 3 can be fixed on the floor, so that the pipeline body 1 is quickly installed below the floor. Once the connection of the pipeline body 1 leaks, the water leaking out will gather at the bottom of the connector groove 506 on the lower tool seat 501, and the gathered water will finally contact the bentonite 604 through the water leakage plate 602, after the water contacts the bentonite 604, the bentonite 604 will swell rapidly, after the bentonite 604 swells, the piston 605 will be pushed to move downward, after the piston 605 moves downward, the elastic metal sheet 607 will be pressed on the power supply pin 608, so as to turn on the power supply of the buzzer 609, after the power supply of the buzzer 609 is turned on, it will emit a prompt sound, so as to detect that the connection of the section pipeline leaks, and remind the user to handle the leakage point in time.
