Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically a leak-proof device for heating pipelines. Background Technology

[0002] Heating pipe networks are a core component of centralized heating systems. Essentially, they are a "heat energy transmission network" that uses pipes, valves, insulation layers, and other equipment to deliver hot water or steam generated by heat sources to thousands of households, providing users with heating or domestic heat. To prevent leaks in heating pipe networks during operation, a leak-proof device for heating pipe networks is needed.

[0003] In traditional heating networks, adjacent heating pipes are often connected to each other to ensure stable operation. However, the connection point is a weak link in the network. This is because it is a joint between two pipe sections rather than a single piece of pipe, resulting in gaps and stress concentration points in the physical structure. Consequently, after long-term operation, the adjacent heating pipes are prone to leaks, which in turn affects the stable operation of the system. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a leak-proof device for heating pipe networks to solve the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a leak-proof device for a heating pipe network, comprising a heating pipe, a bottom arc-shaped frame overlapping the outer edge of the heating pipe near its bottom, a top arc-shaped frame rotatably connected to the top of the bottom arc-shaped frame, an airbag fixedly mounted on the inner wall of the bottom arc-shaped frame, the side of the airbag near the top being fixedly mounted to the inner wall of the top arc-shaped frame, and the adjacent sides of the airbag away from the bottom and top arc-shaped frames being in close contact, a positioning wheel rotatably connected to the top of the top arc-shaped frame, an adjusting ring fixedly mounted on the top of the positioning wheel, a threaded rod threadedly connected to the inner wall of the adjusting ring, a round rod fixedly mounted at the bottom of the threaded rod, and the outer edge of the round rod slidingly sleeved with the inner wall of the top arc-shaped frame, a positioning groove opened on the outer edge of the positioning wheel, and sealing gaskets fixedly mounted on the inner walls of both the top and bottom arc-shaped frames, with the inner walls of the sealing gaskets in close contact with the outer edge of the heating pipe.

[0006] As a preferred technical solution of this utility model, the top of the top arc-shaped frame is provided with a sliding groove one, the top of the bottom arc-shaped frame is provided with a sliding groove two, the bottom of the inner wall of the sliding groove two is provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is rotatably connected to a limiting plate. The shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the sliding groove two and the inner wall of the sliding groove one.

[0007] As a preferred technical solution of this utility model, a cylinder is fixedly assembled on the top of the limiting plate, and the outer edge of the cylinder is movably sleeved with the inner wall of the first slide groove and the inner wall of the second slide groove. A tension spring is fixedly connected to the bottom of the inner wall of the cylinder, and a positioning rod is fixedly connected to the top of the tension spring. The side of the positioning rod is slidably sleeved with the inner wall of the cylinder.

[0008] As a preferred embodiment of this utility model, an adjustment plate is fixedly mounted on the top of the positioning rod, and an auxiliary rod is fixedly mounted on the bottom of the adjustment plate. The outer edge of the auxiliary rod is slidably sleeved with the inner wall of the top arc-shaped frame.

[0009] As a preferred technical solution of this utility model, a side plate is fixedly assembled on the top of the top arc-shaped frame, an auxiliary cylinder is fixedly assembled on the side of the side plate, a spring is fixedly connected to the side of the inner wall of the auxiliary cylinder, and a protruding rod is fixedly connected to the end of the spring away from the inner wall of the auxiliary cylinder, and the shape and size of the outer edge of the protruding rod are adapted to the shape and size of the concave surface of the positioning groove.

[0010] As a preferred embodiment of this utility model, a contact sensor is fixedly mounted at the bottom of the round rod, and a battery and an audible and visual alarm are fixedly mounted at the top of the top arc-shaped frame near both sides, respectively. The battery is electrically connected to the contact sensor and the audible and visual alarm.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This leak-proof heating pipe network device uses a combination of a bottom arc-shaped frame and a top arc-shaped frame. The inner wall of the bottom arc-shaped frame overlaps with the outer edge of the heating pipe near the bottom. Then, by rotating the bottom and top arc-shaped frames, the inner wall of the auxiliary sealing gasket is brought into close contact with the outer edge of the heating pipe, thus ensuring a stable and tight fit between the adjacent surfaces of the auxiliary airbag and the outer edge of the heating pipe. The device is then fitted onto the outer edge of the heating pipe. An adjusting plate, through a cylinder, moves the outer edge of the limiting plate through the inner walls of slide groove one and slide groove two to the inner wall of the arc-shaped groove. Rotating the adjusting plate then limits the outer edge of the limiting plate to the inner wall of the arc-shaped groove. Moving the adjusting plate further allows the tension spring to pull the positioning rod downwards within the inner wall of the cylinder. The positioning rod, through the adjusting plate, causes the outer edge of the auxiliary rod to be limited against the inner wall of the top arc-shaped frame, thus ensuring convenient installation of the bottom and top arc-shaped frames while maintaining a stable seal inside the device.

[0012] 2. This heating pipeline leak prevention device uses an adjusting ring and a positioning wheel in combination. The adjusting ring drives the positioning wheel to rotate, which in turn drives the threaded rod to adjust the height. The threaded rod then drives the contact sensor to adjust the height via a round rod. A spring then pushes a convex rod to move within the inner wall of the auxiliary cylinder. The convex surface of the convex rod engages with the concave surface of the positioning groove, which in turn assists the positioning wheel in working with the adjusting ring to limit the movement of the contact sensor. This facilitates the adjustment of the trigger threshold for airbag deformation caused by heating pipeline leaks. Attached Figure Description

[0016] Please see Figures 1-8A leak-proof device for a heating pipe network includes a heating pipe 1. A bottom arc-shaped frame 2 overlaps the outer edge of the heating pipe 1 near its bottom. A top arc-shaped frame 3 is rotatably connected to the top of the bottom arc-shaped frame 2. An airbag 4 is fixedly mounted on the inner wall of the bottom arc-shaped frame 2, and the side of the airbag 4 near the top is fixedly mounted to the inner wall of the top arc-shaped frame 3. The adjacent sides of the airbag 4 away from the bottom arc-shaped frame 2 and the top arc-shaped frame 3 are in close contact. A positioning wheel 16 is rotatably connected to the top of the top arc-shaped frame 3. An adjusting ring 17 is fixedly mounted on the top of the positioning wheel 16. A threaded rod 18 is threadedly connected to the inner wall of the adjusting ring 17. A round rod 19 is fixedly mounted on the bottom of the threaded rod 18, and the outer edge of the round rod 19 is slidably sleeved with the inner wall of the top arc-shaped frame 3. A positioning groove 2 is formed on the outer edge of the positioning wheel 16. 1. The inner walls of the top arc-shaped frame 3 and the bottom arc-shaped frame 2 are both fixedly fitted with sealing gaskets 5, and the inner walls of the sealing gaskets 5 are in close contact with the outer edge of the heating pipe 1. There are two heating pipes 1, and the adjacent surfaces of the two heating pipes 1 are connected. Through the cooperation of the top arc-shaped frame 3 and the bottom arc-shaped frame 2, the top arc-shaped frame 3 and the bottom arc-shaped frame 2 are rotated in opposite directions, thereby assisting the top arc-shaped frame 3 and the bottom arc-shaped frame 2 to drive the sealing gaskets 5 to be in close contact with the outer edge of the heating pipe 1, thereby driving the airbag 4 to be stably fitted on the outer edge of the joint of the two heating pipes 1. Through the cooperation of the adjusting ring 17 and the threaded rod 18, the adjusting ring 17 is rotated, thereby using the adjusting ring 17 to drive the threaded rod 18 to adjust the height. At the same time, the adjusting ring 17 drives the positioning wheel 16 to rotate synchronously.

[0017] In a preferred embodiment, the top of the top arc-shaped frame 3 is provided with a first groove 6, the top of the bottom arc-shaped frame 2 is provided with a second groove 7, and the bottom of the inner wall of the second groove 7 is provided with an arc-shaped groove 8. The inner wall of the arc-shaped groove 8 is rotatably connected to a limiting plate 10. The shape and size of the outer edge of the limiting plate 10 are adapted to the shape and size of the inner wall of the second groove 7 and the inner wall of the first groove 6. Through the cooperation of the first groove 6 and the second groove 7, the outer edge of the limiting plate 10 passes through the inner wall of the first groove 6 and the inner wall of the second groove 7 to the inner wall of the arc-shaped groove 8. Then, the limiting plate 10 rotates in the inner wall of the arc-shaped groove 8, thereby assisting the limiting plate 10 in limiting its position.

[0018] In a preferred embodiment, a cylinder 11 is fixedly mounted on the top of the limiting plate 10, and the outer edge of the cylinder 11 is movably sleeved with the inner wall of the first slide groove 6 and the inner wall of the second slide groove 7. A tension spring 12 is fixedly connected to the bottom of the inner wall of the cylinder 11, and a positioning rod 13 is fixedly connected to the top of the tension spring 12. The side of the positioning rod 13 is slidably sleeved with the inner wall of the cylinder 11. Through the cooperation of the tension spring 12 and the positioning rod 13, it is convenient to use the tension spring 12 to pull the positioning rod 13 to the inner wall of the cylinder 11, so that the side of the adjusting plate 14 overlaps with the side of the cylinder 11.

[0019] In a preferred embodiment, an adjusting plate 14 is fixedly mounted on the top of the positioning rod 13, and an auxiliary rod 15 is fixedly mounted on the bottom of the adjusting plate 14. The outer edge of the auxiliary rod 15 is slidably sleeved with the inner wall of the top arc-shaped frame 3. Through the cooperation of the adjusting plate 14 and the auxiliary rod 15, when the tension spring 12 drives the side of the adjusting plate 14 to overlap with the side of the cylinder 11 through the positioning rod 13, the adjusting plate 14 drives the outer edge of the auxiliary rod 15 to connect with the inner wall of the top arc-shaped frame 3, thereby assisting the limiting plate 10 to be stably limited to the inner wall of the arc-shaped groove 8.

[0020] In a preferred embodiment, a side plate 22 is fixedly mounted on the top of the top arc-shaped frame 3, and an auxiliary cylinder 23 is fixedly mounted on the side of the side plate 22. A spring 24 is fixedly connected to the side of the inner wall of the auxiliary cylinder 23, and a protruding rod 25 is fixedly connected to the end of the spring 24 away from the inner wall of the auxiliary cylinder 23. The shape and size of the outer edge of the protruding rod 25 are adapted to the shape and size of the concave surface of the positioning groove 21. Through the cooperation of the spring 24 and the protruding rod 25, the spring 24 pushes the protruding rod 25 to move in the inner wall of the auxiliary cylinder 23, and then the convex surface of the protruding rod 25 contacts the concave surface of the positioning groove 21, thereby assisting the positioning wheel 16 to be stably limited.

[0021] In a preferred embodiment, a contact sensor 20 is fixedly mounted at the bottom of the round rod 19, and a battery 26 and an audible and visual alarm 9 are fixedly mounted at the top of the top arc-shaped frame 3 near both sides. The battery 26 is electrically connected to the contact sensor 20 and the audible and visual alarm 9. Through the cooperation of the contact sensor 20 and the airbag 4, the round rod 19 drives the contact sensor 20 to adjust its position. When a leak occurs at the adjacent joint surface of the heating pipe 1, causing the airbag 4 to deform, the outer edge of the airbag 4 comes into contact with the contact sensor 20, thereby triggering an alarm through the audible and visual alarm 9. The addition of the battery 26 provides auxiliary power to the internal components of the device, thereby assisting in the stable operation of the device.

[0022] Working principle: When the device is in use, the bottom arc-shaped frame 2 and the top arc-shaped frame 3 rotate in opposite directions along the outer edge of the heating pipe 1, thereby causing the inner wall of the auxiliary sealing gasket 5 to fit tightly against the outer edge of the heating pipe 1, and the auxiliary airbag 4 to be fitted onto the outer edge of the heating pipe 1. Then, the adjusting plate 14 drives the outer edge of the limiting plate 10 through the inner wall of the first slide groove 6 and the inner wall of the second slide groove 7 to the inner wall of the arc-shaped groove 8 via the cylinder 11. Then, while the positioning rod 13 moves within the inner wall of the cylinder 11, the adjusting plate 14 is rotated. After releasing the adjusting plate 14, the tension spring 12 pulls the positioning rod 13 within the inner wall of the cylinder 11, causing the outer edge of the auxiliary rod 15 to align with the inner wall of the top arc-shaped frame 3, and the auxiliary airbag 4 to be fitted onto the outer edge of the heating pipe 1. The outer edge of the auxiliary limiting plate 10 is limited by the inner wall of the arc groove 8. The adjusting ring 17 is rotated, and the adjusting ring 17 drives the positioning wheel 16 to rotate. At the same time, the adjusting ring 17 drives the threaded rod 18 to adjust the height. The threaded rod 18 is used to adjust the mounting height of the contact sensor 20 through the round rod 19. Then the adjusting ring 17 is released, so that the spring 24 pushes the convex rod 25 to move in the inner wall of the auxiliary cylinder 23. Then the convex surface of the convex rod 25 is used to connect with the concave surface of the positioning groove 21, so that the auxiliary positioning wheel 16 drives the contact sensor 20 to limit the position. When the heating pipe 1 leaks, the outer edge of the airbag 4 comes into contact with the contact sensor 20, and the contact sensor 20 alarms the outside through the sound and light alarm 9.
