Description

Technical Field

[0001] The invention relates to the field of thermal pipes, and in particular to a thermal pipe with a leakage detection component. Background Art

[0002] Thermal pipes, also known as thermal pipelines, are generally heating pipes that start from boiler rooms, direct-fired engine rooms, heating centers, etc., and lead from heat sources to the thermal entrances of buildings. Under normal circumstances, the design pressure of the hot water medium for heating is less than or equal to 2.5MPa, and the design temperature is less than or equal to 200℃; the design pressure of the steam medium for heating is less than or equal to 1.6MPa, and the design temperature is less than or equal to 350℃.

[0003] Thermal pipes need to be tested for leaks during use to prevent leaks from affecting pipe safety and heating. The conventional detection method is to install a leak detection tape on one side of the thermal pipe. The leak detection tape has two sensing wires. When a leak occurs, liquid soaks the leak detection tape and connects to the sensing wires. By detecting the tiny voltage changes on the sensing wires, it is possible to tell whether a leak occurs. However, since the thermal pipe is a pressure pipe, the liquid leaking from the leak point may spray to the external area, causing the leaked liquid to not necessarily contact the installed leak detection tape, resulting in missed detection, resulting in relatively low detection efficiency.

[0004] Therefore, how to solve the above-mentioned shortcomings of the prior art is the subject of the present invention. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses a thermal pipe with a leakage detection component.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: a thermal pipe with a leakage detection assembly, comprising a leakage detection belt, both sides of which are embedded with sensing wires along the length direction thereof, and also comprising a plurality of outer pipe sleeves for being sleeved on the outer side of the thermal pipe and spliced ​​together;

[0007] The outer tube sleeve comprises a fixed sleeve, one side of which is slidably connected with a movable sleeve along its axial direction, a spring is arranged between the fixed sleeve and the movable sleeve, the spring acts on the movable sleeve, the outer side surface of the movable sleeve is concavely provided with a circle of embedded groove along its circumference, and the other side of the fixed sleeve is convexly provided with a convex ring that fits in the embedded groove along its circumference. When splicing, the convex ring of one of the adjacent outer tube sleeves is inserted into the embedded groove of the other, and the convex ring and the embedded groove are also detachably adsorbed together by a magnet, and a gap is left between the outer tube sleeve and the thermal pipe;

[0008] The leakage detection belt is located in the gap, and the leakage detection belt is extended along the length direction of the outer pipe sleeve and is correspondingly arranged below the thermal pipe.

[0009] In the above scheme, the bottom end of the outer sleeve is concavely provided with a slot corresponding to the leakage detection belt and engaging with it, and the inner cavity wall of the outer sleeve is formed with guiding inclined surfaces extending obliquely toward the slot on both sides along the length direction of the slot.

[0010] In the above scheme, a circle of extension sleeve is protruding from the side of the fixed sleeve facing the movable sleeve, and the movable sleeve is provided with a circle of groove corresponding to the extension sleeve. The groove is slidably sleeved on the extension sleeve along the axial direction of the fixed sleeve, and the outer end of the extension sleeve is evenly distributed with multiple springs along its circumference, and the outer end of each spring is connected to the inner wall surface of the groove.

[0011] In the above scheme, a plurality of connecting grooves are provided on the leakage detection belt along its length direction, and two ends of each connecting groove are respectively connected to the two sensing wires.

[0012] In the above solution, a resistance heating wire is embedded and installed in the inner cavity of the leakage detection belt along its length direction.

[0013] In the above solution, a plurality of support blocks are arranged along the circumference of the inner wall surface of the fixing sleeve, and the outer ends of the support blocks are against the thermal pipe.

[0014] In the above solution, the support blocks between adjacent outer sleeves are arranged in a staggered manner.

[0015] The beneficial effects of the present invention are as follows: the thermal pipe of the present invention has a set of multiple outer pipe sleeves arranged on the outside of the thermal pipe and spliced ​​together, the leakage detection belt is extended along the length direction of the outer pipe sleeve and is correspondingly arranged below the thermal pipe, when the thermal pipe leaks, such as leakage at the top or side, the leakage can be blocked by the inner wall surface of the outer pipe sleeve and finally gathered to the bottom surface of the inner cavity of the outer pipe sleeve, and then the leakage of the thermal pipe can be timely detected by the leakage detection belt. Compared with the traditional detection structure, it can improve the accuracy of detection; at the same time, the outer pipe sleeves are combined together by splicing, which is convenient for installation and disassembly; the outer pipe sleeve also includes a slidable movable sleeve, which can be opened during maintenance to check the working condition of the thermal pipe.

[0022] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] Example: See Figure 1-6 A thermal pipe with a leakage detection component is used for leakage detection of a horizontally arranged thermal pipe 200. It includes a leakage detection belt 100. Both sides of the leakage detection belt 100 are embedded with sensing wires 101 along the length direction thereof. The leakage detection belt 100 uses an existing detection belt. The ends of the sensing wires 101 are connected to form a detection loop. When water enters between the two sensing wires 101, since water is also a conductive substance, a weak current (about 2 mA) passing through the water causes a voltage change in the circuit, thereby sounding an alarm; (different types of leakage detection belts 100 can be used for different media, such as ASC1100 detection belt for water leakage detection and ASC9100 detection belt for oil leakage detection);

[0024] The heat pipe 200 further includes a plurality of outer pipe sleeves 300 which are sleeved on the outside of the heat pipe 200 and spliced ​​together;

[0025] The outer tube sleeve 300 includes a fixed sleeve 301, one side of the fixed sleeve 301 is connected to a movable sleeve 302 in an axially sliding manner, a spring 303 is arranged between the fixed sleeve 301 and the movable sleeve 302, and the spring 303 acts on the movable sleeve 302. Specifically, the fixed sleeve 301 is provided with a circle of extension sleeve 311 protruding toward the side of the movable sleeve 302, and the movable sleeve 302 is provided with a circle of groove 322 corresponding to the extension sleeve 311, and the groove 322 is axially slidably sleeved on the extension sleeve 311 along the fixed sleeve 301. The outer end of the extension sleeve 311 is uniformly provided with a plurality of springs 303 along its circumference, and the outer end of each spring 303 is connected to the inner wall surface of the groove 322; the movable sleeve 302 can slide open toward the fixed sleeve 301, so as to check the working condition of the internal thermal pipe 200 during maintenance, and after the movable sleeve 302 is released, the movable sleeve 302 returns to its position under the action of the spring 303;

[0026] The outer side surface of the movable sleeve 302 is concavely provided with a circle of embedding grooves 321 along its circumference, and the other side of the fixed sleeve 301 is convexly provided with a convex ring 304 that fits in the embedding groove 321 along its circumference. When splicing, the convex ring 304 of one of the adjacent outer sleeves 300 is inserted into the embedding groove 321 of the other, and the convex ring 304 and the embedding groove 321 are also detachably adsorbed together by a magnet. Specifically, a circle of iron sheets can be connected to the convex ring 304, and a magnet is set in the inner cavity of the embedding groove 321, so that the two can be adsorbed together by magnetic force, thereby improving the firmness during splicing;

[0027] A gap is left between the outer pipe sleeve 300 and the thermal pipe 200, and the leakage detection belt 100 is located in the gap. The leakage detection belt 100 is extended along the length direction of the outer pipe sleeve 300 and is correspondingly arranged below the thermal pipe 200;

[0028] A plurality of outer pipe sleeves 300 are integrally sleeved on the outside of the thermal pipe 200, and the leakage detection tape 100 is extended along the length direction of the outer pipe sleeve 300 and is correspondingly arranged below the thermal pipe 200. When the thermal pipe 200 leaks, such as leakage at the top or side, the leaked liquid can be blocked by the inner wall surface of the outer pipe sleeve 300 and finally converge to the bottom surface of the inner cavity of the outer pipe sleeve 300 under the action of gravity, and then the leakage detection tape 100 arranged on the bottom surface of the inner cavity can be used to timely detect whether the thermal pipe 200 is leaking. Compared with the traditional detection structure, it can improve the accuracy of detection; at the same time, the outer pipe sleeve 300 is combined together by splicing, which is convenient for installation and disassembly; the outer pipe sleeve 300 also includes a slidable movable sleeve 302, which can be opened during maintenance to check the working condition of the thermal pipe 200.

[0029] In order to improve the liquid gathering effect on the bottom surface of the inner cavity of the outer tube sleeve 300, a groove 305 is recessed at the bottom end of the outer tube sleeve 300 corresponding to the leakage detection tape 100 and is engaged with the groove 305. The inner cavity wall of the outer tube sleeve 300 is formed with guide slopes 351 extending obliquely toward the groove 305 on both sides along the length direction of the groove 305. When the thermal pipe 200 leaks, the gathered liquid can be immersed into the leakage detection tape 100 placed in the groove 305 through the guide slope 351.

[0030] In order to further improve the detection capability of the leakage detection belt 100, a plurality of connecting grooves 102 are opened on the leakage detection belt 100 along its length direction. The two ends of each connecting groove 102 are respectively connected to two sensing wires 101. The connecting grooves 102 can be used to contain leaked liquid to make the sensing wires 101 on both sides of the leakage detection belt 100 conductive.

[0031] A resistance heating wire 103 is embedded in the inner cavity of the leakage detection tape 100 along its length direction. After the thermal pipe 200 is repaired, the resistance heating wire 103 can heat the leakage detection tape 100 to quickly dry the part originally immersed in the liquid.

[0032] A plurality of support blocks 312 are arranged along the circumference of the inner wall surface of the fixing sleeve 301 . The outer ends of the support blocks 312 abut against the heat pipe 200 to provide support and separate the two.

[0033] The support blocks 312 between adjacent outer sleeves 300 are staggered so that there are gaps between the support blocks 312 , which reduces the blocking effect on the liquid in the outer sleeve 300 during leakage and helps the liquid to converge toward the bottom of the outer sleeve 300 .

[0034] It should be noted that the above content only illustrates the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications all fall within the protection scope of the claims of the present invention.
