The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a buried pipe elbow assembly. Referring to fig. 1 and 2, in an embodiment of the present application, a buried pipe elbow assembly 100 may comprise: an outer tube 110, a core tube 120, a cap 130, and a vibration sensor 140. The outer tube 110 may be sleeved outside the core tube 120. The cap 130 may be provided with a through hole, the core tube 120 may be inserted into the through hole, and the core tube 120 may be fixedly connected to the cap 130. The cap 130 may cover an end of the outer tube 110, and the cap 130 is spaced apart from the end of the outer tube 110. The vibration sensor 140 may be provided to the cap 130.

In this way, in the embodiment of the present application, the supply of the heating medium can be performed using the core tube 120, and the core tube 120 can be safely protected using the outer tube 110. When the core tube 120 vibrates, the vibration of the core tube 120 may be detected using the vibration sensor 140 provided on the cap 130 of the core tube 120, and an operational safety hazard may be predicted in advance based on the detection result of the vibration sensor 140. In this way, the vibration sensor 140 can be used to perform vibration detection on the core tube 120 in real time, so that whether the potential safety hazard occurs in the core tube 120 can be found in time during the operation of the core tube 120.

In addition, since the ground pipe elbow 100 may be connected to other pipe sections, when the other pipe sections vibrate, the vibration of the other pipe sections may be transmitted to the ground pipe elbow 100, and thus, it may be determined whether a safety hazard occurs to the other pipe sections connected to the ground pipe elbow 100 using the vibration sensor 140.

It should be noted that, in the embodiment of the present application, a heat insulating material may be disposed in the gap between the outer pipe 110 and the core pipe 120, so that the heat insulating performance of the buried pipe elbow assembly 100 may be improved. The core tube 120 may be fixedly connected to the tube cap 130 by a connection structure, and of course, the core tube 120 may also be fixedly connected to the tube cap 130 by welding, and the connection manner between the core tube 120 and the tube cap 130 is not limited in the embodiments of the present application.

Referring to fig. 1 and 2, in an embodiment of the present application, the buried pipe elbow assembly 100 may further include a temperature sensor 150. The temperature sensor 150 may be connected with the tube cap 130, and the temperature sensor 150 may include a temperature sensing part 151, and the temperature sensing part 151 may be disposed in a gap between the outer tube 110 and the core tube 120. In this way, the temperature of the gap between the outer tube 110 and the core tube 120 can be detected using the temperature sensor 150. Thus, when a leakage, a pipe burst, or the like occurs in the core pipe 120, the temperature sensor 150 can detect that the temperature of the gap between the outer pipe 110 and the core pipe 120 has changed, and it can be determined whether the leakage, the pipe burst, or the like occurs in the core pipe 120 based on the detection structure of the temperature sensor 150.

In the embodiment of the present application, it is possible to finally determine whether a leakage, a pipe burst, etc. occurs in the core pipe 120 by combining the sensing structures of the vibration sensor 140 and the temperature sensor 150. Alternatively, when one of the vibration sensor 140 and the temperature sensor 150 detects an abnormality in the core tube 120, the inground tube elbow assembly 100 can be serviced by a service person to determine if a leak, a pipe burst, etc. has occurred in the core tube 120.

In an embodiment of the present application, the core tube 120 may include a first straight tube part 121, a second straight tube part 122, and an elbow part 123. The first straight pipe portion 121 and the second straight pipe portion 122 may be connected to both ends of the bent pipe portion 123, respectively, and the pipe cap 130 may be fixedly connected to the first straight pipe portion 121 of the core pipe 120. For example, in the embodiment of the present application, the extending direction of the first straight tube portion 121 and the extending direction of the second straight tube portion 122 may be perpendicular.

In an embodiment of the present application, an end of the temperature detection part 151 far from the cap 130 may be flush with an end of the first straight pipe part 121 near the bent pipe part 123. In this way, the temperature sensor 150 can be made to better acquire the gap temperature between the outer tube 110 and the core tube 120.

Illustratively, in embodiments of the present application, the temperature sensor 150 may be a thermocouple-type temperature sensor. Of course, in the embodiment of the present application, the temperature sensor 150 may also be a thermal resistance type temperature sensor, or other types of sensors, which are not listed here.

Referring to fig. 1 and 3, in an embodiment of the present application, the buried pipe elbow assembly 100 may further include a displacement sensor 160, and the displacement sensor 160 may include a body portion 161 and a displacement detection portion 162. One of the body portion 161 and the displacement detecting portion 162 may be connected with the cap 130, and the other may be connected with the outer tube 110. In this way, it is possible to determine whether the relative displacement of the core tube 120 and the outer tube 110 occurs using the displacement sensor 160. When the relative displacement of the core tube 120 and the outer tube 110 occurs, it is considered that one of the core tube 120 and the outer tube 110 is deformed.

Illustratively, in embodiments of the present application, the displacement sensor 160 may be a pull-wire type displacement sensor. Of course, in the embodiment of the present application, the displacement sensor 160 may be other types of displacement sensors, and it is only necessary that the displacement sensor 160 can acquire the relative displacement parameter between the core tube 120 and the outer tube 110.

In the embodiment of the present application, the edge of the cap 130 may be provided with a bent portion 131, the bent portion 131 may face the outer tube 110, and the bent portion 131 may be sleeved outside the outer tube 110. Thus, when leakage, pipe burst and the like occur in the core pipe 120, the pipe cap 130 can be used for preventing the heat-conducting medium in the core pipe 120 from overflowing, and the potential safety hazard can be reduced.

In an embodiment of the present application, in the case that the buried pipe elbow assembly 100 includes the displacement sensor 160, the main body portion 161 of the displacement sensor 160 may be connected with the bent portion 131 of the pipe cap 130, and the displacement detection portion 162 of the displacement sensor 160 may be connected with the outer pipe 110. For example, in the case where the displacement sensor 160 is a pull-wire type displacement sensor, the main body portion of the displacement sensor 160 may be provided at the bent portion 131, and the pull wire of the displacement sensor 160 may be connected to the outer tube 110.

In embodiments of the present application, the buried pipe elbow assembly 100 may further comprise a trap 170 and a switching valve. One end of the water drainage pipe 170 may be disposed in the gap between the outer pipe 110 and the core pipe 120, and the other end of the water drainage pipe 170 may pass through the cap 130 to be exposed outside the cap 130. An end portion of the drain pipe 170 between the outer pipe 110 and the core pipe 120 may be connected to a bottom portion of the second straight pipe portion 122, and a switching valve may be provided to the drain pipe 170. For example, the second straight tube portion 122 may be provided with an opening at a position opposite to the end of the drain tube 170, and the end of the drain tube 170 may be connected to the opening. Thus, when the condensed water occurs in the underground pipe elbow assembly 100 and the pipe section connected to the underground pipe elbow assembly 100, the switching valve may be in an open state, and the condensed water may be discharged through the drain pipe 170 by using the air pressure in the core pipe 120.

For example, in the embodiment of the present application, two switching valves may be provided, so that when the switching valve located at the outer side is in a failure state, the switching valve located at the inner side may be in a closed state, and thus, the switching valve located at the outer side may be repaired or replaced with the switching valve located at the inner side in the closed state.

It should be noted that in embodiments of the present application, cap 130 may be located off-ground, and the sensors included in the ground elbow assembly 100 may be disposed on cap 130, thereby facilitating replacement of a damaged sensor when the sensor is damaged.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
