Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically a structure for real-time monitoring of pipeline temperature in heating units. Background Technology

[0002] Heating pipelines are piping systems used to transport hot water, steam, or other heat media, providing heating, hot water, or industrial heating in buildings or industrial facilities. Heating pipelines equipped with temperature monitoring capabilities can utilize various sensors and monitoring devices to measure the temperature of the medium within the pipeline system in real time and transmit this data to a monitoring system or operation control center.

[0003] However, in existing heating pipelines with temperature monitoring functions, if the temperature monitor malfunctions or the system ages and requires repair, replacement, or system upgrades, the integrated fixing method of the monitor with the pipeline makes subsequent work very inconvenient. This results in the need for many cumbersome tools to disassemble the monitor, wasting the staff's time. Therefore, to address the above shortcomings, a heating pipeline with temperature monitoring function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a structure for real-time monitoring of pipeline temperature in heating units, so as to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A real-time temperature monitoring structure for a heating unit pipeline includes a pair of heating pipelines, with a monitoring pipe section between them. A connector is installed on the side of the monitoring pipe section. The top surface of the connector has a slot and a threaded groove, all coaxially aligned. The threaded groove surrounds the slot. A through hole is formed on the side of the monitoring pipe section, communicating with the slot. A rubber rod is installed within the slot, with an interference fit between the rubber rod and the slot and through hole. A knob is coaxially connected to the top of the rubber rod, and a contact temperature sensor is installed at the bottom of the rubber rod, located inside the monitoring pipe section. The bottom surface of the knob is coaxially connected to... A threaded ring surrounds a rubber rod, and the threaded ring and threaded groove are threadedly connected. The connector is fixedly fitted to the monitoring pipe section. The slot and through hole provide an installation channel for the rubber rod. The rubber rod is interference-fitted with the slot and through hole, and the threaded connection between the threaded ring and the threaded groove enables stable installation of the contact temperature sensor in the monitoring pipe section, ensuring the accuracy of temperature monitoring. Furthermore, rotating the knob moves the threaded ring up and down within the threaded groove, thereby causing the rubber rod and the contact temperature sensor to move synchronously. This allows for the installation and removal of the contact temperature sensor without the need for cumbersome tools, saving time for workers. The interference fit structure also enhances the sealing of the connection, preventing media leakage within the monitoring pipe section.

[0007] Furthermore, a connecting sleeve is installed on the inner wall of the monitoring pipe section. The top, interior, and bottom surfaces of the connecting sleeve are respectively provided with a first cylindrical hole, a conical hole, and a second cylindrical hole. The through hole, the first cylindrical hole, the conical hole, and the second cylindrical hole are sequentially connected. A connecting plate is installed in the second cylindrical hole. The connecting plate has several openings. A plug bead slides in the conical hole, and the plug bead can block the bottom end of the first cylindrical hole. A spring connects the connecting plate and the plug bead. A rubber rod slides in the first cylindrical hole and is interference-fitted with the first cylindrical hole. A push rod is installed at the center of the bottom surface of the rubber rod, and the push rod can engage with the top of the plug bead. The plug bead contacts and is pressed against the inner wall of the monitoring pipe section. The first cylindrical hole, conical hole, and second cylindrical hole inside form a sensor installation channel. The push rod and rubber rod are fixedly engaged. When the rubber rod drives the contact temperature sensor to be inserted, the push rod can press the plug bead down along the conical hole, allowing the contact temperature sensor to pass smoothly through the channel and contact the medium in the monitoring pipe section, ensuring the accuracy of temperature monitoring. When the contact temperature sensor is replaced, the rubber rod is removed, and the elastic force of the spring pushes the plug bead back to its original position, blocking the bottom of the first cylindrical hole to prevent the medium in the monitoring pipe section from leaking. The opening of the connecting plate can ensure that the medium flows into the conical hole.

[0008] Furthermore, the radius of the first cylindrical hole is smaller than the radius of the second cylindrical hole. The smaller end of the conical hole is connected to the first cylindrical hole, and the larger end of the conical hole is connected to the second cylindrical hole. The radius of the first cylindrical hole is smaller than the radius of the second cylindrical hole, and both ends of the conical hole are connected to both. This size fit allows the plug bead to fit against the bottom end of the first cylindrical hole under the action of the spring, thereby achieving a seal. After the plug bead moves down, the medium can flow in from the gap between the plug bead and the conical hole and come into contact with the contact temperature sensor.

[0009] Furthermore, each of the two heating pipes is equipped with a first flange at one end close to the other, and each end of the monitoring pipe section is equipped with a second flange. The first flange and the second flange are connected by bolts. The first flange of the heating pipe and the second flange of the monitoring pipe section are connected by bolts. This detachable connection method makes the installation and removal of the monitoring pipe section and the heating pipe more convenient. When the entire monitoring pipe section needs to be repaired, replaced or upgraded, there is no need to modify the main body of the heating pipe. The monitoring pipe section can be removed simply by removing the bolts, which reduces the difficulty of maintenance and saves maintenance time and costs.

[0010] Furthermore, several sealing rings are installed on the outer side of the rubber rod. These sealing rings fit tightly against the inner wall of the rubber rod, the slot, and the first cylindrical hole. Based on the interference fit between the rubber rod and each component, the sealing performance at the connection is further enhanced, effectively preventing the heat medium in the monitoring pipe section from leaking from the gap between the rubber rod and the slot and the first cylindrical hole, thus ensuring the normal operation of the heating system and the safety of temperature monitoring.

[0011] Furthermore, both the knob and the rubber rod have interconnected wire grooves inside. These grooves provide a channel for storing and protecting the connecting wires of the contact temperature sensor, preventing them from being exposed to the outside and subjected to wear, corrosion, or external pulling. This ensures stable signal transmission between the contact temperature sensor and the external monitoring system, while also making the overall structure neater and facilitating wiring and maintenance.

[0012] Furthermore, the knob has an anti-slip texture on its side. The anti-slip texture on the side of the knob increases the friction between the operator's hand and the knob, preventing slippage when rotating the knob to install or remove the contact temperature sensor. This allows the operator to operate the knob more easily and efficiently, improving the convenience and safety of the installation and removal process.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: The real-time temperature monitoring structure for the heating unit's pipelines, through the engagement of knobs, threaded rings, and threaded grooves in the connectors, combined with the interference fit between the rubber rod and the slotted, through-hole, and first cylindrical hole, allows for quick assembly and disassembly of the contact temperature sensor without the need for cumbersome tools, saving workers' time. Secondly, the monitoring pipe section is bolted to the heating pipeline via first and second flanges, facilitating the overall maintenance, replacement, and upgrade of the monitoring pipe section. In summary, this structure, through the rational coordination of its components, solves the problems of cumbersome assembly and disassembly and inconvenient maintenance of temperature monitors in existing technologies, while ensuring the accuracy of temperature monitoring and the safety and stability of the heating system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5This utility model provides a technical solution: a real-time temperature monitoring structure for a heating unit pipeline, including a pair of heating pipelines 1, with a monitoring pipe section 2 between the pair of heating pipelines 1. A connector 5 is installed on the side of the monitoring pipe section 2. The top surface of the connector 5 has a slot 13 and a threaded groove 14, and the connector 5, slot 13, and threaded groove 14 are all coaxially arranged. The threaded groove 14 surrounds the slot 13. A through hole is opened on the side of the monitoring pipe section 2, and the slot 13 and the through hole are connected. A rubber rod 9 is installed in the slot 13, and the rubber rod 9 is interference-fitted with the slot 13 and the through hole. A knob 6 is coaxially connected to the top of the rubber rod 9, and a contact temperature sensor 12 is installed at the bottom of the rubber rod 9. The contact temperature sensor 12 is located inside the monitoring pipe section 2. A threaded ring 7 is coaxially connected to the bottom surface of the knob 6, and the threaded ring 7 surrounds the rubber rod 9. The rod 9, threaded ring 7, and threaded groove 14 are threaded together. First, the contact temperature sensor 12 is installed at the bottom end of the rubber rod 9. Then, the rubber rod 9 is inserted into the slot 13 of the connector 5, passing through the through hole of the monitoring pipe section 2 until the contact temperature sensor 12 enters the monitoring pipe section 2. Then, the knob 6 is rotated, which drives the threaded ring 7 to tighten downward along the threaded groove 14. The threaded ring 7 pushes the rubber rod 9 further downward, so that the rubber rod 9 fits tightly with the slot 13 and the through hole to achieve an interference fit, thus completing the installation and fixing of the contact temperature sensor 12. At this time, the contact temperature sensor 12 can monitor the temperature of the medium in the monitoring pipe section 2 in real time. When disassembly is required, the knob 6 is rotated in the opposite direction, and the threaded ring 7 moves upward along the threaded groove 14, which drives the rubber rod 9 and the contact temperature sensor 12 to be pulled out upward simultaneously, achieving quick disassembly and assembly.

[0022] As an embodiment of this utility model, further, a connecting sleeve 15 is installed on the inner wall of the monitoring pipe section 2. The top surface, interior, and bottom surface of the connecting sleeve 15 are respectively provided with a first cylindrical hole 16, a conical hole 17, and a second cylindrical hole 18. The through hole, the first cylindrical hole 16, the conical hole 17, and the second cylindrical hole 18 are connected in sequence. A connecting plate 21 is installed in the second cylindrical hole 18. The connecting plate 21 has several openings 22. A plug bead 19 slides in the conical hole 17. The plug bead 19 can block the bottom end of the first cylindrical hole 16. A spring 20 is connected between the connecting plate 21 and the plug bead 19. The rubber rod 9 slides in the first cylindrical hole 16 and is pressurized with the first cylindrical hole 16. A push rod 11 is installed at the center of the bottom surface of the rubber rod 9. The push rod 11 can contact the top end of the plug bead 19 and squeeze the plug bead 19. When it is necessary to install the contact temperature sensor 12, the rubber rod 9 is first... Insert the rubber rod 9 into the slot 13 of the connector 5 and slide it along the first cylindrical hole 16. Then, the push rod 11 on the bottom of the rubber rod 9 contacts the top of the plug bead 19. As the rubber rod 9 continues to move down, the push rod 11 exerts a continuous squeezing force on the plug bead 19, causing the plug bead 19 to overcome the elastic force of the spring 20 and slide along the conical hole 17 toward the second cylindrical hole 18. At this time, the first cylindrical hole 16 and the conical hole 17 are connected, and the contact temperature sensor 12 enters the conical hole 17 and directly contacts the medium in the pipe for temperature monitoring. When it is necessary to replace the contact temperature sensor 12, rotate the knob 6 in the opposite direction to move the rubber rod 9 upward. The squeezing force of the push rod 11 on the plug bead 19 disappears, the spring 20 restores its elastic deformation, and pushes the plug bead 19 to slide upward along the conical hole 17 until the plug bead 19 is tightly attached to the bottom of the first cylindrical hole 16, blocking the first cylindrical hole 16 and preventing medium leakage.

[0023] In one embodiment of this utility model, the radius of the first cylindrical hole 16 is smaller than the radius of the second cylindrical hole 18. The smaller end of the conical hole 17 is connected to the first cylindrical hole 16, and the larger end of the conical hole 17 is connected to the second cylindrical hole 18. Since the smaller end of the conical hole 17 is connected to the first cylindrical hole 16 and the larger end is connected to the second cylindrical hole 18, and the radius of the first cylindrical hole 16 is smaller than the radius of the second cylindrical hole 18, when the spring 20 pushes the plug bead 19 upward, the plug bead 19 will be stuck into the bottom end of the first cylindrical hole 16, thus achieving a seal.

[0024] As an embodiment of this utility model, a pair of heating pipes 1 are further provided with a first flange 3 at their respective ends that are close to each other, and a second flange 4 is provided at both ends of the monitoring pipe section 2. The first flange 3 and the second flange 4 are connected by bolts. During installation, the second flanges 4 at both ends of the monitoring pipe section 2 are first aligned with the first flanges 3 of the pair of heating pipes 1, so that the bolt holes on the flanges correspond one-to-one. Then, the bolts are passed through the corresponding bolt holes, and the nuts are tightened to make the first flange 3 and the second flange 4 fit tightly together, thereby achieving a fixed connection between the heating pipe 1 and the monitoring pipe section 2, ensuring that the heat medium can flow smoothly from the heating pipe 1 into the monitoring pipe section 2. When it is necessary to disassemble the monitoring pipe section 2, the nuts are first loosened, the bolts are removed, and then the second flanges 4 at both ends of the monitoring pipe section 2 are separated from the first flanges 3 of the heating pipe 1, so that the monitoring pipe section 2 can be removed for subsequent operations.

[0025] As an embodiment of this utility model, further, a plurality of sealing rings 10 are installed on the outer side of the rubber rod 9. When the rubber rod 9 is inserted into the slot 13 and the first cylindrical hole 16, the sealing rings 10 on the outer side of the rubber rod 9 are elastically deformed by the compression of the inner wall of the slot 13 and the first cylindrical hole 16. The outer surface of the sealing rings 10 is tightly fitted with the inner wall of the slot 13 and the first cylindrical hole 16, filling the tiny gaps between the rubber rod 9 and each component, forming multiple sealing barriers, preventing the heat medium in the monitoring pipe section 2 from leaking through the gaps, while not affecting the sliding of the rubber rod 9 during the disassembly and assembly process.

[0026] As an embodiment of this utility model, both the knob 6 and the rubber rod 9 have interconnected wire grooves 8 inside. The connecting wire of the contact temperature sensor 12 is led out from the bottom of the rubber rod 9, passes through the wire groove 8 inside the rubber rod 9, and then extends to the outside through the interconnected wire groove 8 inside the knob 6 to connect with the monitoring system. The wire groove 8 serves to limit and protect the connecting wire. During the disassembly and assembly of the rubber rod 9 and the knob 6, the connecting wire moves synchronously with the wire groove 8 to avoid friction, entanglement or pulling of the connecting wire with other components, thus ensuring the integrity and stability of the signal transmission line.

[0027] Specifically, the top of the contact temperature sensor 12 is provided with an external thread, and the bottom of the rubber rod 9 is provided with an internal thread hole that matches the external thread. During installation, align the threaded end of the contact temperature sensor 12 with the internal thread hole at the bottom of the rubber rod 9, and rotate the contact temperature sensor 12 clockwise until it is tightly fitted with the bottom end face of the rubber rod 9 to achieve a threaded fastening connection. This ensures that the sensor is installed stably and is not prone to shaking due to the flow of the pipeline medium. At the same time, after the connecting wire passes through the wire groove 8, the wire groove 8 is waterproofed and sealed. After the connecting wire of the contact temperature sensor 12 is led out from its terminal, it passes through the wire through hole reserved on the side of the internal thread hole at the bottom of the rubber rod 9 and goes upward along the wire groove 8 inside the rubber rod 9. The wire extends through the internal groove 8 of the knob 6 and exits from the top of the knob 6. The connection method after exiting the groove is selected according to the sensor type: if it is a resistance temperature detector (RTD) contact temperature sensor 12, a three-wire connection method is used, and the three connection wires are respectively connected to the positive signal terminal, negative signal terminal, and compensation terminal of the monitoring system to eliminate the influence of wire resistance on measurement accuracy; if it is a digital contact temperature sensor 12, the data line, power line, and ground line are respectively connected to the corresponding GPIO interface, power interface, and ground interface of the monitoring system, and pull-up resistors are configured at the interface to ensure stable signal transmission, and finally realize the real-time transmission of temperature data collected by the contact temperature sensor 12 to the monitoring system.

[0028] As an embodiment of this utility model, the side of the knob 6 is provided with anti-slip texture. When the operator needs to rotate the knob 6, the hand comes into contact with the anti-slip texture on the side of the knob 6. The anti-slip texture increases the frictional resistance between the hand and the knob 6, so that the rotational force applied by the operator can be more effectively transmitted to the knob 6, avoiding slippage due to sweaty hands or smooth surface, ensuring that the knob 6 can rotate smoothly, driving the threaded ring 7 to move in the threaded groove 14, realizing the quick installation or removal of the contact temperature sensor 12.

[0029] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
