Description

Technical Field

[0001] This utility model relates to the field of heating pipeline monitoring technology, and more specifically, to a heating pipeline leakage monitoring device. Background Technology

[0002] In heating systems, heating pipes are key components for transporting heat energy. Because these pipes operate under high pressure and high temperature for extended periods, and are susceptible to corrosion and external damage, leaks are common. Heating pipe leaks not only waste energy and increase heating costs, but can also damage the surrounding environment and even cause safety accidents.

[0003] Current heating pipeline leak monitoring devices include structures such as temperature sensors, flow sensors, pressure sensors, data acquisition units, microprocessors, and alarm modules. Temperature sensors are typically magnetically or adhesively fixed to the outer wall of the heating pipe. This requires keeping the outer wall of the heating pipe clean before installation. However, since the temperature sensor is exposed on the outside without protection, it directly contacts the sensor surface and monitoring location in rainy or snowy weather. Rainwater or snow covering the pipe surface alters the heat transfer characteristics of the pipe surface, affecting the temperature sensor's measurement results and making it impossible to accurately determine if a leak has occurred. Therefore, a structure that can protect the temperature monitoring location is needed. Based on this, we propose a heating pipeline leak monitoring device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heating pipeline leakage monitoring device to solve the technical problem that the current temperature monitoring location lacks shielding protection, resulting in the temperature monitoring accuracy being affected by rain or snow.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a heating pipe leakage monitoring device, including a temperature sensor installed on the main body of the heating pipe, a base fixedly installed on the main body of the heating pipe connected to the outside of the temperature sensor, and the bottom side of the base has the same shape as the top arc surface of the heating pipe body, and a shielding cover for shielding the temperature sensor is fixedly installed on the top of the base.

[0006] The temperature sensor has a connecting plate fixedly installed on each of its opposite sides, and the base has a positioning groove that engages with the connecting plate on each of its opposite sides.

[0007] The base has several docking slots at the top near the positioning slot, and the bottom of the shield is fixed with a docking block that is inserted into the docking slot.

[0008] This invention restricts the temperature detection location by connecting a base to the outside of the temperature sensor. Combined with a shield, the temperature sensor can be enclosed, thus protecting it from rain or snow and reducing the impact of rain and snow on the temperature at the monitoring location. This ensures stable heat transfer temperature on the surface of the heating pipe. Simultaneously, this structural design increases the protection of the temperature sensor, reducing the impact of rain and snow on its detection performance. The identical shape of the connecting surfaces between the base and the heating pipe reduces gaps, minimizing rain and snow leakage and maintaining the accuracy of the temperature sensor's detection.

[0009] Preferably, a groove is provided on one side of the docking block, a spring is fixedly provided on the inner side of the groove, a locking block that fits against the inner wall of the groove is fixedly provided on the side end of the spring, and the bottom corner of the locking block is a rounded corner.

[0010] Preferably, the base has a slot on its side that communicates with the docking groove, and the top side of the locking block fits into the top side of the slot.

[0011] Preferably, the base is movably mounted with a pressing member on one side of the slot, and the side end of the pressing member is located inside the slot and abuts against and fits against the locking block.

[0012] Preferably, the extrusion component includes a horizontal plate, an extrusion block with the same shape as the slot is fixedly provided on one side of the horizontal plate, a threaded rod is movably installed in the middle of the horizontal plate, and a threaded hole for connecting the threaded rod is provided on the side wall of the base.

[0013] Preferably, the shielding cover has a downwardly protruding blocking frame fixedly provided on the outer edge near the bottom, and the inner side of the blocking frame is fitted and connected to the outer side of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model restricts the temperature detection position by connecting a base to the outside of the temperature sensor. With the help of a shield, the temperature sensor can be enclosed inside, thus protecting it from rain or snow and reducing the impact of rain and snow on the temperature at the monitoring position. This makes the heat transfer temperature on the surface of the heating pipe body stable. At the same time, this structure can increase the protection of the temperature sensor and reduce the impact of rain and snow on the temperature sensor detection performance. The fact that the connecting surfaces between the base and the heating pipe body are the same shape can reduce the existence of gaps, reduce the occurrence of rain and snow leakage, and maintain the accuracy of the temperature detected by the temperature sensor.

[0016] 2. This utility model also uses a locking block protruding from the side of the docking block to lock into the slot, which can position the shielding cover in place. With the setting of the extrusion part, the locking block can be easily squeezed into the groove. This structure facilitates the disassembly of the shielding cover and makes it easy to regularly check the temperature sensor. The structure is simple, the operation is convenient, and it saves the staff's testing time. Attached Figure Description

Detailed Implementation

[0023] like Figures 1 to 5 As shown, this utility model relates to a heating pipe leakage monitoring device, which includes a temperature sensor 2 installed on the heating pipe body 1. The outside of the temperature sensor 2 is connected to a base 3 fixedly installed on the heating pipe body 1, and the bottom side of the base 3 has the same arc shape as the top of the heating pipe body 1. A shield 4 is fixedly installed on the top of the base 3 to shield the temperature sensor 2. The base 3 can limit the monitoring position of the temperature sensor 2, and the shield 4 can include the temperature sensor 2, reducing the impact of external environmental changes on temperature monitoring.

[0024] A connecting plate 201 is fixedly provided on both opposite sides of the temperature sensor 2, and a positioning groove 301 that engages with the connecting plate 201 is provided on both facing sides of the base 3. The engagement of the connecting plate 201 and the positioning groove 301 can locate the installation position of the temperature sensor 2, reduce the positioning time, and improve the installation speed.

[0025] Several docking slots 302 are provided on the top of the base 3 near the positioning slot 301. The bottom of the shield 4 is fixed with a docking block 401 that is inserted into the docking slot 302. The position of the shield 4 can be positioned by inserting the docking block 401 into the docking slot 302, so as to achieve the effect of quick alignment and connection.

[0026] In an embodiment of this utility model, a groove 402 is provided on one side of the docking block 401, and a spring 403 is fixedly provided on the inner side of the groove 402. A locking block 404 that fits against the inner wall of the groove 402 is fixedly provided on the side end of the spring 403, and the bottom corner of the locking block 404 is a rounded corner. The locking block 404 can be easily moved by extension and retraction through the support of the spring 403. The rounded corner design can reduce resistance when moving downward and make it easy to squeeze into the groove 402.

[0027] In an embodiment of this utility model, a slot 303 communicating with the docking groove 302 is provided on the side of the base 3, and the top side of the locking block 404 fits against the top side of the slot 303. A pressing member 5 is movably installed on one side of the base 3 located in the slot 303. The side end of the pressing member 5 is located inside the slot 303 and abuts against the locking block 404. The opening of the slot 303 makes it easy for the protruding end of the locking block 404 to be inserted, thereby limiting the position of the docking block 401. The setting of the pressing member 5 makes it easy to squeeze out the side end of the locking block 404, which facilitates the release of the limiting of the shield 4.

[0028] In an embodiment of this utility model, the extrusion member 5 includes a horizontal plate 501. An extrusion block 502 with the same shape as the slot 303 is fixedly provided on one side of the horizontal plate 501. A threaded rod 503 is movably installed in the middle of the horizontal plate 501, and a threaded hole 304 connected to the threaded rod 503 is provided on the side wall of the base 3. The position of the extrusion block 502 can be easily adjusted by the threaded connection between the threaded rod 503 and the threaded hole 304, so as to achieve the effect of pushing the positioning block 404 to move. The length of the extrusion block 502 is the same as the length of the slot 303.

[0029] In an embodiment of this utility model, a downwardly protruding sealing frame 405 is fixedly provided on the outer edge of the shield 4 near the bottom, and the inner side of the sealing frame 405 is in close contact with the outer side of the base 3; the sealing frame 405 can be used to seal the joint between the base 3 and the shield 4, thereby reducing the gap.

[0030] Working Principle: This embodiment provides a heating pipeline leakage monitoring device. In use, the base 3 is first fixed to the location where the temperature needs to be monitored by adhesive or welding. Then, the side ends of the connecting plates 201 extending from both sides of the temperature sensor 2 are inserted into the positioning groove 301. This positions the temperature sensor 2, and under the pressure, the temperature sensor 2 adheres to the heating pipe body 1, thus completing the installation of the temperature sensor 2. Next, a shield 4 can be placed on top of the base 3 to enclose the temperature sensor 2. The mating block 401 is inserted into the mating groove 302 to position the connection. During the mating process, the protruding locking block 404 on the side of the mating block 401 is pressed into the groove 402. When the mating block 401 is in place, the side end of the locking block 404... Aligning with the slot 303, the locking block 404 loses its squeezing force and can spring back to its original position under the elastic force of the spring 403. This allows the side end of the locking block 404 to be inserted into the slot 303, thus fixing the position of the shield 4. When the shield 4 needs to be removed, the threaded rod 503 on the squeezing member 5 can be rotated to move it into the threaded hole 304, allowing the squeezing block 502 to move closer to the locking block 404 along the slot 303. With continuous movement, the locking block 404 can be squeezed into the groove 402, thereby releasing the limiting restriction and facilitating the separation of the shield 4 from the base 3. This makes it easier to inspect the temperature sensor 2. The overall structure protects the monitoring position of the temperature sensor 2, reduces the impact of temperature difference changes on the temperature monitoring data, and improves the accuracy of temperature monitoring.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
