[0002] The thermal network, also known as the thermal pipeline, is a heating pipeline that starts from the boiler room, direct-fired machine room, heating center, etc. and leads from the heat source to the thermal entrance of the building.
[0003] At present, thermal pipelines are generally installed by direct burial, that is, the pipelines are installed in the soil. After long-term use, the thermal pipelines are constantly impacted and vibrated by water flow (water mass) and corrosion, and the thermal pipelines are prone to leakage or even damage. When leakage occurs, since the pipelines are buried underground and there is a lack of real-time detection devices for the thermal pipelines, it is often not detected until the heat loss is more serious, resulting in large losses each time.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0021] Reference Figure 1-3A detection device for thermal network production includes a thermal pipeline 1 and a limit clamp. The limit clamp and the thermal pipeline 1 can be detachably installed together. The limit clamp includes an upper jacket 10 and a lower jacket 3 installed relatively. Both ends of the upper jacket 10 and the lower jacket 3 extend outward to form a fixed convex surface 12. The fixed convex surfaces 12 of the upper jacket 10 and the lower jacket 3 are fixed together by stainless steel bolts. The fixed cavity formed by the upper jacket 10 and the lower jacket 3 can be installed on the thermal pipeline 1. When maintenance or replacement is required, the stainless steel bolts are removed, and then the upper jacket 10 and the lower jacket 3 are separated, so that the separation operation of the limit clamp and the thermal pipeline 1 can be completed.
[0022] Reference Figure 1 and Figure 2 As shown, the upper end surface of the upper jacket 10 is recessed inward to form a detection cavity 9, in which a vibration sensor 11 and a temperature sensor 8 are installed. A vibration and temperature detection part is installed on a more complex pipe section of the thermal pipeline 1. The vibration sensor 11 can monitor the vibration of the thermal pipeline itself in real time, and judge the abnormal vibration of the pipeline by the vibration value (for example, if the flange connection of the pipeline is not tight, the vibration will increase, but it is not limited to the above one situation), so as to remind the staff to take corresponding measures in time.
[0023] Reference Figure 1 and Figure 2 As shown, the outer surface of the thermal pipe 1 is provided with a temperature measuring cable 2 electrically connected to the temperature sensor 8. The temperature measuring cable 2 is distributed on the thermal pipe 1 in a straight line or a spiral shape. The temperature measuring cable 2 and the temperature sensor 8 are combined to form a temperature measuring component that satisfies the temperature measurement of the thermal pipe 1. The temperature inside the thermal insulation shell 13 can be collected in real time through the temperature measuring component. When the thermal pipe 1 leaks, hot water or steam will leak out, causing the internal temperature of the insulation layer 4 to be too high. When it exceeds the set range, it can be known that damage has occurred. When an abnormal situation occurs, the staff is reminded in time to take corresponding measures, thereby avoiding greater losses.
[0024] Among them, the temperature measuring component formed by the combination of the temperature measuring cable 2 and the temperature sensor 8 is an existing technology that has been realized, and the details will not be elaborated.
[0025] Furthermore, the outer end of the thermal pipe 1 is provided with an insulating outer shell 13, and the inner wall of the insulating outer shell 13 is provided with a groove for embedding the temperature measuring cable 2. The above design can help limit the position of the temperature measuring cable 2, thereby ensuring the subsequent temperature measurement quality.
[0026] Furthermore, an internal thread is provided on the upper inner wall of the detection cavity 9, and a protective cover 5 is threadedly installed at the internal thread of the detection cavity 9. A PCB main board 7 electrically connected to the vibration sensor 11 and the temperature sensor 8 is installed in the protective cover 5. A transmission cable 6 electrically connected to the external control terminal and the power supply is provided on one side of the PCB main board 7. A through hole is opened on the protective cover 5 to allow the transmission cable 6 to pass through. The data of the vibration sensor 11 and the temperature sensor 8 can be collected in real time through the PCB main board 7, and the data can be transmitted to the control terminal (such as a mobile phone, computer, etc.), so that when an abnormal situation occurs, the staff can understand the situation in time, thereby avoiding greater losses.
[0027] Wherein, waterproof sealant is also coated on the connection between the through hole and the transmission cable 6 .
[0028] Furthermore, a heat-insulating layer 4 for heat preservation is embedded inside the upper jacket 10 and the lower jacket 3. The designed heat-insulating layer 4 can reduce heat loss while meeting the requirements of temperature and vibration measurement.
[0029] The heat-insulating layer 4 is made of heat-insulating materials. Since there are many heat-insulating materials, they are not listed one by one here.
[0030] Furthermore, the upper jacket 10, the lower jacket 3 and the protective cover 5 are all made of stainless steel.
[0031] A vibration and temperature detection part is installed on the more complex pipe section of the thermal pipeline. The vibration sensor 11 can monitor the vibration of the thermal pipeline 1 itself in real time, judge the abnormal vibration of the pipeline by the vibration value, and remind the staff to take corresponding measures in time.
[0032] At the same time, the temperature inside the insulation shell 4 can be collected in real time through the temperature measuring component. When the thermal pipe 1 leaks, hot water or steam will leak out, causing the temperature inside the insulation layer 4 to be too high. When it exceeds the set range, it can be known that damage has occurred, and then the data can be transmitted to the control terminal in time to remind the staff that maintenance is needed, thereby avoiding greater losses and facilitating the subsequent discovery of the leakage point, making subsequent maintenance more convenient.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
