[0002] With the growth of global energy demand and the advancement of marine resource development, the marine engineering equipment industry has gradually become one of the important strategic industries in the world. The main equipment includes marine platforms, submarine pipelines, deep-sea exploration equipment, offshore wind power facilities, etc. Among them, marine platforms are key facilities in many fields such as global energy mining, economic development, technological innovation, and energy security. At the same time, in order to meet the daily water needs of workers (such as drinking, washing, cooking, etc.), a complete set of fresh water supply pipelines will be laid.
[0003] In the traditional laying of water supply pipes, the socket-and-spigot method has become a more common method of laying pipes due to its simple operation. Construction workers often use simple tools such as rubber hammers to control the movement of plastic pipes along a certain route to connect the pipes and complete the laying. However, due to the uneven accuracy of individual operations, manual operation has limitations and it is difficult to control the insertion depth of the pipe, which makes the pipeline system after laying a huge hidden danger in terms of sealing. In order to solve this problem, we propose a plastic pipe laying device. Summary of the invention

A fixed frame is slidably installed on the inner wall of the opening. A sealing ring is installed on the side of the fixed frame away from the rotating block. The sealing ring is slidably installed on the inner wall of the water pipe. A second tension spring is fixedly installed on the outer wall of the fixed frame facing the plastic pipe, and the second tension spring is fixedly connected to the water pipe. When the sleeve drives the rotating block to rotate, the limit block rises, and the clamp drives the plastic pipe to move into the water pipe, and the plastic pipe squeezes the sealing ring. At this time, the second tension spring is stretched. After the rotating block is reset, the limit block descends to limit the plastic pipe. At this time, the second tension spring contracts, and the sealing ring is always in contact with the plastic pipe. At the same time, the limit assembly limits the sealing ring in one direction.
[0006] Preferably, the sealing ring is provided with a cutout on one side facing the plastic pipe, and the inner wall of the cutout is respectively provided with a first sealing ring sleeved on the outer wall of the plastic pipe and a second sealing ring abutting against one end of the plastic pipe, and a third sealing ring is installed at the abutment between the sealing ring and the water pipe.

At this time, the first slide plate drives the plastic pipe to move into the water pipe through the clamping jaw. At this time, the plastic pipe will squeeze the first sealing ring, and the first sealing ring will be deformed and sleeved on the outer wall of the plastic pipe. As the plastic pipe continues to move, it will abut against the second sealing ring, and then squeeze the sealing ring to move. The sealing ring drives the fixed frame to move in the opening, and at the same time the fixed frame stretches the second tension spring.

The second sealing ring on the sealing ring will always abut against one end of the plastic pipe, thereby ensuring the sealing performance.
[0014] 3. The present invention is provided with a limiting component. When the tension of the second tension spring drives the sealing ring to move, the sealing ring drives the fixed frame to move, and the extrusion block inside the fixed frame will slide on the inclined groove.

DETAILED DESCRIPTION
[0017] In order to more clearly understand the purpose, technical solutions and advantages of the present application, the present application is described and illustrated below in conjunction with the accompanying drawings and embodiments.
[0018] See also Figures 1 to 9 The present invention provides a technical solution: a plastic pipe laying device, including a support frame 101, a plastic pipe 1 and a water pipe 9, and also includes: The conveying mechanism includes a moving component and a clamping jaw 105; the moving component drives the plastic pipe 1 to the side of the water pipe 9 through the clamping jaw 105 for quantitative conveying; The rotating mechanism includes a second slide plate 106, a plurality of extrusion plates 107 are evenly installed on the outer wall of the second slide plate 106, a round pin 108 is abutted against the outer wall of the extrusion plate 107, and a sleeve 109 is installed on the inner wall of the round pin 108; when the extrusion plate 107 squeezes the round pin 108, the round pin 108 drives the sleeve 109 to rotate; The compensation mechanism includes a limit assembly, a limit block 2 and a rotating block 3. The rotating block 3 is sleeved on the outside of the water pipe 9. The outer wall of the water pipe 9 is provided with a plurality of openings 20, and the openings 20 are located inside the rotating block 3. A fixed frame 17 is slidably installed on the inner wall of the opening 20. A sealing ring 16 is installed on the side of the fixed frame 17 away from the rotating block 3. The sealing ring 16 is slidably installed on the inner wall of the water pipe 9. A second tension spring 12 is fixedly installed on the outer wall of the fixed frame 17 facing the plastic pipe 1. The second tension spring 12 is fixedly connected to the water pipe 9. When the sleeve 109 drives the rotating block 3 to rotate, the limit block 2 rises, and the clamping jaw 105 drives the plastic pipe 1 to move into the water pipe 9. The plastic pipe 1 squeezes the sealing ring 16. At this time, the second tension spring 12 is stretched. After the rotating block 3 is reset, the limit block 2 descends to limit the plastic pipe 1. At this time, the second tension spring 12 contracts, and the sealing ring 16 is always in contact with the plastic pipe 1. At the same time, the limit assembly limits the sealing ring 16 in one direction.
[0019] Further, such as Figure 5 and Figure 6 As shown, the sealing ring 16 is provided with a cutout on the side facing the plastic pipe 1, and the inner wall of the cutout is respectively installed with a first sealing ring 11 sleeved on the outer wall of the plastic pipe 1 and a second sealing ring 1601 abutting against one end of the plastic pipe 1, and a third sealing ring 1602 is installed at the abutment between the sealing ring 16 and the water pipe 9; The first sealing ring 11 is sleeved on the outside of the plastic pipe 1 for the first sealing, and the second tension spring 12 drives the sealing ring 16 to move toward the side of the plastic pipe 1 through the fixed frame 17, so that the second sealing ring 1601 and the plastic pipe 1 abut against each other for the second sealing. When the sealing ring 16 slides, the third sealing ring 1602 seals between the sealing ring 16 and the water pipe 9.
[0020] Further, such as Figure 3 and Figure 4 As shown, a plurality of fixing rods 4 are installed on the outer walls of both sides of the rotating block 3, and the outer wall of the fixing rod 4 is rotatably connected to a first tension spring 5, and the first tension spring 5 is rotatably connected to a fixing block 6 on the side away from the fixing rod 4, and the fixing block 6 is installed on the outer wall of the water pipe 9 on the side away from the first tension spring 5; The first tension spring 5 is used to drive the rotating block 3 to reset, and the first tension spring 5 can rotate on the fixing rod 4 and the fixing block 6 respectively.
[0021] Further, such as Figure 7 and Figure 8 As shown, the limiting assembly includes a plurality of second slide grooves 19 symmetrically opened on the inner wall of the rotating block 3, a round rod 13 is slidably installed on the inner wall of the second slide groove 19, a slider 14 is slidably installed on the outer wall of the round rod 13, a limiting rod 21 is symmetrically installed on the outer wall of the slider 14, the slider 14 is slidably installed inside the fixed frame 17, a spring 18 is installed on the upper end surface of the slider 14, an extrusion block 15 is installed on the side of the spring 18 away from the slider 14, a plurality of inclined grooves 10 are evenly opened on the inner wall of the rotating block 3, a guide rod 1301 is symmetrically abutted against the outer wall of the round rod 13, and the guide rod 1301 is fixedly installed on the outer wall of the water pipe 9; After the rotating block 3 is reset, the second slide groove 19 squeezes the round rod 13, and the round rod 13 moves up and down in the guide rod 1301. The round rod 13 drives the slider 14 to move up and down in the fixed frame 17. At this time, the limit rod 21 limits the slider 14. At the same time, the extrusion block 15 abuts against the inclined groove 10. At this time, the extrusion block 15 can only move toward the side close to the plastic pipe 1 to achieve one-way limiting of the sealing ring 16. In this embodiment, in order to ensure that the extrusion block 15 and the inclined groove 10 can fit closely, the elastic coefficients of the upper spring 18 and the lower spring 18 are different.
[0022] Further, such as Figure 3 and Figure 5As shown, the outer wall of the rotating block 3 facing the limiting block 2 is evenly provided with a plurality of first sliding grooves 7, the inner wall of the first sliding groove 7 is slidably mounted with a sliding rod 8, the sliding rod 8 is rotatably connected to the limiting block 2, and the limiting block 2 is penetrated by a water pipe 9 on the side away from the sliding rod 8; When the rotating block 3 drives the first sliding groove 7 to squeeze the sliding rod 8, the sliding rod 8 drives the limiting block 2 to rise or fall.
[0023] Further, such as Figure 1 and Figure 2 As shown, the moving assembly includes a first electric telescopic rod 102, which is mounted on a support frame 101, and a first slide plate 103 is mounted on the output shaft of the first electric telescopic rod 102, and a handle 104 is symmetrically threadedly connected to the outer wall of the first slide plate 103, and the handle 104 is fixedly connected to a clamping claw 105, and the first slide plate 103 is slidably mounted on the support frame 101, and a sliding rod 8 is mounted on the outer wall of the clamping claw 105, and the sliding rod 8 is slidably connected to the first slide plate 103; The handle 104 is turned to make the clamping claw 105 clamp the plastic pipe 1. At this time, the slide bar 8 prevents the clamping claw 105 from rotating. Then the first electric telescopic rod 102 is extended to drive the first slide plate 103 to slide. The first slide plate 103 drives the plastic pipe 1 to move toward the water pipe 9 through the clamping claw 105.
[0024] Further, such as Figure 1 As shown, the plastic pipe 1 is corrugated and has elasticity; Compensation is performed by the plastic pipe 1 so that it is always in contact with the sealing ring 16 .
[0025] Further, such as Figure 2 As shown, the sleeve 109 is rotatably connected to a fixed plate 110 at a side away from the second slide plate 106, the lower end surface of the fixed plate 110 is fixedly mounted on the support frame 101, and a second electric telescopic rod 111 is mounted on the outer wall of the fixed plate 110, and the output shaft of the second electric telescopic rod 111 is fixedly connected to the second slide plate 106; When the second electric telescopic rod 111 is working, it drives the second slide plate 106 to slide, and the second slide plate 106 drives the extrusion plate 107 to move, and the extrusion plate 107 squeezes or moves away from the round pin 108. At this time, the sleeve 109 rotates on the fixed plate 110.
[0026] Working principle: Step 1: First, put the support frame 101 into the outside of the water pipe 9 (the water pipe 9 is in a fixed state), and the sleeve 109 is sleeved on the outside of the rotating block 3. Then, the plastic pipe 1 is placed between the clamping jaws 105, with one side abutting against the outer wall of the water pipe 9. Then, turn the handle 104, and the clamping jaws 105 clamp the plastic pipe 1. Then, the second electric telescopic rod 111 contracts, driving the second slide plate 106 to move, and the second slide plate 106 drives the extrusion plate 107 to move. The second extrusion plate 107 squeezes the round pin 108, and the round pin 108 drives the sleeve 109 to rotate. The sleeve 109 drives the rotating block 3 to rotate. At this time, the rotating block 3 stretches the first tension spring 5 through the fixed rod 4, and the rotating block 3 drives the first slide groove 7 and the second slide groove 19 to rotate. The first slide groove 7 squeezes the slide rod 8, and the slide rod 8 drives the limit block 2 to move upward, so that the limit block 2 is away from the plastic pipe 1. When the second slide groove 19 rotates, it will squeeze the round rod 13, and the round rod 13 will drive the slider 14 to move in the fixed frame 17 to the side away from the rotating block 3. The limiting rod 21 limits the slider 14. At this time, the slider 14 drives the extrusion block 15 to move downward through the spring 18, and the extrusion block 15 is away from the inclined groove 10 inside the rotating block 3.
[0027] Step 2: Control the first electric telescopic rod 102 to extend, and at this time the first slide plate 103 drives the plastic pipe 1 to move into the water pipe 9 through the clamping claw 105. At this time, the plastic pipe 1 will squeeze the first sealing ring 11, and the first sealing ring 11 will be deformed and sleeved on the outer wall of the plastic pipe 1. As the plastic pipe 1 continues to move, it will abut against the second sealing ring 1601, and then squeeze the sealing ring 16 to move, and the sealing ring 16 drives the fixed frame 17 to move in the opening 20, and at the same time the fixed frame 17 stretches the second tension spring 12; When the first electric telescopic rod 102 is fully extended, the fixed frame 17 abuts against the outer wall of the opening 20, and then the second electric telescopic rod 111 is controlled to extend. The second electric telescopic rod 111 extends, driving the second slide plate 106 to move, the extrusion plate 107 no longer squeezes the round pin 108, and the sleeve 109 no longer applies force to the rotating block 3. At this time, the first tension spring 5 contracts and drives the rotating block 3 back to the initial position through the fixed rod 4. The rotating block 3 drives the first slide groove 7 and the second slide groove 19 to rotate in the opposite direction. The first slide groove 7 squeezes the slide rod 8. At this time, the slide rod 8 drives the limit block 2 to move toward the groove of the plastic pipe 1 and extends into the inside of the groove; At the same time, the second slide groove 19 squeezes the round rod 13 , and the round rod 13 drives the slider 14 to move on the fixed frame 17 toward the side close to the rotating block 3 , and the slider 14 drives the squeezing block 15 to abut against the inclined groove 10 through the spring 18 .
[0028] Step 3: By turning the handle 104, the plastic pipe 1 is no longer clamped, and then the first electric telescopic rod 102 is controlled to shrink, so that the first slide plate 103 returns to the initial position. At this time, the second tension spring 12 shrinks, driving the fixed frame 17 to move toward the side of the plastic pipe 1 in the opening 20, and the fixed frame 17 drives the sealing ring 16 to squeeze the plastic pipe 1. Since the limit block 2 fixes the plastic pipe 1 at this time, the plastic pipe 1 will abut against the second sealing ring 1601 on the sealing ring 16, and the device is taken out from one side of the plastic pipe 1. One side of the plastic pipe 1 is connected to the faucet through a buckle, and the laying of the water supply pipe is completed at this time.
[0029] Step 4: At this time, the tension of the second tension spring 12 will drive the sealing ring 16 to always abut against the plastic pipe 1 to keep it sealed. At the same time, the extrusion block 15 inside the fixed frame 17 will slide on the inclined groove 10. The inclined groove 10 can prevent the extrusion block 15 from moving away from the plastic pipe 1, thereby ensuring the sealing of the water supply pipe after laying.
