Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating pipeline equipment technology, and in particular to a heating pipeline with leakage protection. Background Technology
[0002] A heating network is a pipeline system used to transport and distribute heating media from heat sources to heat users. The heating network transmits heat from the heat source to the user through primary and secondary networks. The primary network is the supply and return water network from the heat source to the heating station, while the secondary network is the supply and return water network from the heating station to the user. In the heating station, the high-temperature water from the primary network transfers heat to the water in the secondary network through heat exchangers, and then the secondary network delivers the heat to the user's home.
[0003] The connection between heating pipes is often made by welding, which has poor sealing performance. If the welding is not done properly, the heating pipes are prone to damage and cracking during long-term use, resulting in water leakage in the pipe network. Furthermore, the water in the current heating pipes is hot and flows at high speeds. If a leak occurs, it will pose a great safety hazard to maintenance personnel. Currently, there is no mechanism to protect heating pipes from water leaks. Utility Model Content

Detailed Implementation
[0029] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0031] The heating pipe 1 includes a first heating pipe 11 and a second heating pipe 12; the first heating pipe 11 and the second heating pipe 12 are first connected together internally by the snap-fit mechanism 3; the external connection part of the first heating pipe 11 and the second heating pipe 12 is provided with a mounting bracket 2; the mounting bracket 2 is provided with pressure sensors 4 on four sides near the heating pipe 1; the first heating pipe 11 is provided with a first blade 5 inside; the first blade 5 is fixed on the first heating pipe 11; the second blade 6 is rotatably installed inside the first heating pipe 11 by the drive assembly 7; the second blade 6 abuts against the end face of the first blade 5.
[0032] The external connection portions of the first heating pipe 11 and the second heating pipe 12 are connected together by welding.
[0033] The drive motor 71, the pressure sensor 4, and the external controller are electrically connected.
[0034] The snap-fit mechanism 3 includes a stepped portion 31, a pressure spring 32, a limiting sealing gasket 33, a limiting groove 34, a snap-fit groove 35, and a snap-fit block 36;
[0035] The lower end of the second heating pipe 12 is provided with the stepped portion 31; the stepped portion 31 is connected to the limiting sealing gasket 33 through the pressure spring 32; the inner wall of the first heating pipe 11 is provided with the limiting groove 34 for mounting the limiting sealing gasket 33 to rotate; a plurality of snap-fit grooves 35 are evenly provided on the stepped portion 31; a snap-fit block 36 is provided on the inner wall of the first heating pipe 11 and at the right end of the limiting groove 34; the snap-fit block 36 can snap into the inside of the snap-fit groove 35.
[0036] Each of the four limiting sealing gaskets 33 is provided and is arc-shaped; when the four limiting sealing gaskets 33 are engaged with the limiting groove 34, they form a complete ring-shaped sealing gasket.
[0037] The snap-fit groove 35 is an inverted L-shape that is narrower on the left and wider on the right; the width of the snap-fit block 36 is the same as the width of the slot on the narrow side of the snap-fit groove 35 on the left.
[0038] The drive assembly 7 includes a drive motor 71, a first bevel gear 72, a second bevel gear 73, and a rotating shaft 74;
[0039] The first heating pipe 11 is provided with the drive motor 71 at the top; the output shaft of the drive motor 71 is connected to the first bevel gear 72; the first bevel gear 72 meshes with the second bevel gear 73; the second bevel gear 73 is fixed on the rotating shaft 74; the second blade 6 is fixedly connected to the rotating shaft 74.
[0040] Working principle: When the first heating pipe 11 and the second heating pipe 12 are connected, the snap-fit block 36 is first snapped into the snap-fit groove 35, and then the second heating pipe 12 is pushed. The pressure spring 32 is compressed under the action of compression, so that the limiting sealing gasket 33 is also snapped into the rotation limiting groove 34. At this time, the second heating pipe 12 is rotated, so that the snap-fit block 36 enters the slotted position at the upper right end of the snap-fit groove 35.
[0041] When the pressure sensor 4 installed inside the mounting bracket 2 senses the water pressure, a leak occurs at the pipe connection. The drive motor 71 then starts, causing the first bevel gear 72 to mesh with the second bevel gear 73 for transmission. This causes the second blade 6 to rotate. At this time, the second blade 6 and the first blade 5 block the water inlet of the first heating pipe 11. The first blade 5 and the second blade 6 are in an overlapping state without leakage. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
