Description

Technical Field

[0001] This application relates to the field of heat exchange station technology, and in particular to a safety monitoring and alarm device for heat exchange stations. Background Technology

[0002] In the daily operation of a heat exchange station, pipeline pressure is one of the key parameters for ensuring the safety and stability of the system. Real-time and accurate monitoring of pipeline pressure and timely alarm in case of abnormality are of great significance for preventing equipment damage and avoiding safety accidents.

[0003] Currently, pressure sensors are typically used to detect pipeline pressure in heat exchange stations. These sensors are often installed using traditional flange or threaded connections, which require specialized tools such as wrenches for disassembly and installation. This is not only cumbersome but also time-consuming and labor-intensive, especially when regular inspections or replacements of the pressure sensors are needed, severely impacting maintenance efficiency. Furthermore, in terms of pipeline pressure monitoring and alarm functions, some existing pressure sensors lack alarm functionality or can only provide on-site alarms, resulting in limited functionality and poor practicality.

[0004] Therefore, we propose a safety monitoring and alarm device for heat exchange stations to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a safety monitoring and alarm device for heat exchange stations, which enables rapid installation and removal of pressure sensors without the need for complex tools, simplifying the installation and maintenance process. It also enables dual alarms, both on-site and remote, allowing staff to quickly be aware of abnormal situations and promptly handle them, thus ensuring the safe operation of the heat exchange station.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a safety monitoring and alarm device for a heat exchange station, comprising a hollow plug joint welded and fixed to the top of the heat exchange station pipeline, and a pressure sensor detachably installed and fixed on the hollow plug joint. The bottom end of the hollow plug joint extends into the heat exchange station pipeline, and the bottom end of the pressure sensor slides through the hollow plug joint. A pressure detection probe is fixedly connected to the bottom end of the pressure sensor. A sealing ring is fixedly installed on the inner side wall of the hollow plug joint, and the inner ring of the sealing ring slides and seals against the outer side wall of the hollow plug joint. Slots are provided on both sides of the top of the hollow plug joint, and crossbars are fixedly installed on both sides of the pressure sensor. Each crossbar has a fixed insert at its bottom. Each insert has a slot on its opposite side. A locking assembly is provided on the hollow connector. The locking assembly includes two locking rods, two annular plates, and two springs. Each slot has a groove on its opposite side. The two locking rods are respectively positioned within their corresponding grooves. The ends of the two locking rods that are close to each other are slidably installed within their respective slots. The two annular plates are fixedly fitted onto their corresponding locking rods. The two springs are fixedly installed on the opposite sides of the two annular plates. The ends of the two springs that are far apart from each other are fixedly installed on the inner walls of the opposite sides of the two grooves. The two springs are respectively fitted onto their corresponding locking rods.

[0007] A further provision of this application is that the number of sealing rings is not less than two.

[0008] A further feature of this application is that the annular plate slides against the inner wall of the groove.

[0009] A further feature of this application is that the locking assembly includes two pull handles, and each of the inner walls of the two grooves on the side away from each other is provided with a clearance hole. The ends of the two levers that are away from each other pass through the corresponding clearance holes, and the two pull handles are respectively fixedly installed on the ends of the two levers that are away from each other.

[0010] A further feature of this application is that a rubber damping ring located above the locking rod is fixedly installed on the inner wall of the slot, and the insertion post is in damping sliding engagement with the inner ring wall of the rubber damping ring.

[0011] A further configuration of this application is as follows: a control box is fixedly installed on the top of the pressure sensor, a controller is fixedly installed inside the control box, an audible and visual alarm is fixedly installed on the top of the control box, and a wireless signal transmitter is fixedly installed on the right outer wall of the control box. The pressure sensor, the audible and visual alarm, and the wireless signal transmitter are all electrically connected to the controller.

[0012] A further feature of this application is that the front side of the control box has an open structure, and a cover plate is fixed to the outer wall of the front side of the control box by screws.

[0013] A further feature of this application is that the cover plate has heat dissipation holes, and a dustproof mesh is fixedly installed inside the heat dissipation holes.

[0014] This application includes at least one of the following beneficial technical effects:

[0015] This application utilizes two pins that engage with corresponding slots, along with a locking structure, to enable rapid installation and removal of pressure sensors without the need for complex tools. This simplifies the installation and maintenance process, allowing staff to replace or repair pressure sensors more efficiently, saving significant time and labor costs.

[0016] This application utilizes the damping characteristics of the rubber damping ring to further enhance the stability of the insertion post in the slot and reduce the loosening of the pressure sensor caused by factors such as pipeline vibration.

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a safety monitoring and alarm device for a heat exchange station, including a hollow connector 2 welded and fixed to the top of a heat exchange station pipeline 1, and a pressure sensor 3 detachably mounted and fixed to the hollow connector 2. The bottom end of the hollow connector 2 extends into the heat exchange station pipeline 1, and the bottom end of the pressure sensor 3 slides through the hollow connector 2. A pressure detection probe 301 is fixedly connected to the bottom end of the pressure sensor 3. The pressure detection probe 301 is used to monitor the pressure inside the heat exchange station pipeline 1 in real time, and the pressure can be displayed on a screen built into the pressure sensor 3 for on-site inspection by personnel. A sealing ring 4 is fixedly installed on the inner side wall of the hollow connector 2. The inner ring of the 4-ring slides and seals against the outer wall of the hollow connector 2. There are at least two sealing rings 4. By setting at least two sealing rings 4, the sealing between the pressure sensor 3 and the hollow connector 2 can be ensured, effectively preventing leakage of the medium in the heat exchange station pipeline 1, ensuring the stability of the monitoring environment, and reducing safety hazards and resource waste caused by leakage. The sealing rings 4 are made of wear-resistant and high-temperature resistant materials, such as graphite sealing rings, copper sealing rings, or stainless steel sealing rings. Slots 5 are provided on both sides of the top of the hollow connector 2. Crossbars 6 are fixedly installed on both sides of the pressure sensor 3. Inserts 7 are fixedly installed at the bottom of both crossbars 6. Each of the two insertion posts 7 has a slot 8 on its opposite side. The hollow connector 2 is equipped with a locking assembly, which includes two locking rods 10, two annular plates 11, and two springs 12. Each of the two slots 8 has a groove 9 on its opposite side. The two locking rods 10 are respectively positioned within their corresponding grooves 9, with their ends slidably mounted within their respective slots 8. The two annular plates 11 are fixedly fitted onto their respective locking rods 10. The two springs 12 are fixedly mounted on the opposite sides of the two annular plates 11, with their ends fixedly mounted on the opposite inner walls of the two grooves 9. The 12 are respectively fitted onto the corresponding locking rods 10. The locking assembly also includes two pull handles 13. The inner walls of the two grooves 9 that are far apart from each other are provided with clearance holes. The far ends of the two locking rods 10 pass through the corresponding clearance holes. The two pull handles 13 are respectively fixedly installed on the far ends of the two locking rods 10. They are inserted into the slots 5 through the insert pins 7. With the locking structure of the locking rods 10 and the slots 8, plus the setting of the pull handles 13, the pressure sensor 3 can be quickly disassembled and assembled without the need for complicated tools. This greatly simplifies the installation and maintenance process and allows the staff to complete the replacement or repair of the pressure sensor 3 more efficiently, saving a lot of time and labor costs.

[0026] In this embodiment, the annular plate 11 slides and fits against the inner wall of the groove 9, ensuring that the locking rod 10 slides smoothly and steadily in the groove 9, thereby ensuring the smooth movement of the locking rod 10 during the locking and unlocking process, making the locking component work more reliably.

[0027] In this embodiment, a rubber damping ring 14 located above the lever 10 is fixedly installed on the inner wall of the slot 5. The insertion post 7 and the inner ring wall of the rubber damping ring 14 are in damping sliding cooperation. By utilizing the damping characteristics of the rubber damping ring 14, the stability of the insertion post 7 in the slot 5 is further enhanced, and the loosening of the pressure sensor 3 caused by factors such as pipeline vibration is reduced.

[0028] In this embodiment, a control box 15 is fixedly installed on the top of the pressure sensor 3, a controller 16 is fixedly installed inside the control box 15, an audible and visual alarm 17 is fixedly installed on the top of the control box 15, and a wireless signal transmitter 18 is fixedly installed on the right outer wall of the control box 15. The pressure sensor 3, the audible and visual alarm 17, and the wireless signal transmitter 18 are all electrically connected to the controller 16. The pressure detection probe 301 at the bottom of the pressure sensor 3 can monitor the pressure value in the heat exchange station pipeline 1 in real time and transmit the data to the controller 16. When the pressure is abnormal (lower or higher than the preset pressure value), the controller 16 can promptly trigger the audible and visual alarm 17. 7. An on-site alarm is issued, and the alarm information is simultaneously transmitted to a remote location, such as a computer in the monitoring room or a staff member's mobile phone, via a wireless signal transmitter 18. This achieves dual alarm functionality, both on-site and remote, allowing staff to quickly become aware of the situation and promptly handle any abnormalities, ensuring the safe operation of the heat exchange station. It should be noted that the audible and visual alarm 17 and the wireless signal transmitter 18 are controlled automatically by the controller 16. The controller 16 is a PLC controller, and its control circuit can be easily programmed by those skilled in the art, which is common knowledge in the field. Therefore, the control method and circuit connection will not be explained in detail here.

[0029] In this embodiment, the front of the control box 15 is open. A cover plate 19 is fixed to the outer wall of the front of the control box 15 by screws. The cover plate 19 has heat dissipation holes, and a dustproof mesh is fixedly installed in the heat dissipation holes. The cover plate 19 on the front of the control box 15 is fixed by screws, which makes it easy to open and inspect and maintain the internal controller 16. The heat dissipation holes on the cover plate 19 help dissipate heat inside the control box 15 and prevent internal components from being affected by high temperature. The dustproof mesh design can prevent dust from entering the control box 15 and ensure the cleanliness and normal operation of internal components.

[0030] Based on the above structure, the working principle of the safety monitoring and alarm device for the heat exchange station provided in this application is as follows:

[0031] When installing pressure sensor 3: Pull the two handles 13 to move them away from each other. The two handles 13 will drive the corresponding locking rods 10 to gradually move out of the corresponding slots 5. The locking rods 10 will drive the annular plate 11 installed on them to move. At this time, the two springs 12 will be compressed and generate elastic force. Then, align the pins 7 at the bottom of the crossbars 6 on both sides of pressure sensor 3 with the corresponding slots 5 and insert them. When the pins 7 pass through the rubber damping ring 14, they will be initially fixed with the help of damping. At the same time, the bottom end of pressure sensor 3 will also be inserted into the hollow connector 2, so that the pressure detection probe 301 is located in the heat exchange station pipeline 1. The sealing ring 4 can effectively seal the gap between the inner wall of the hollow connector 2 and the outer wall of the bottom end of pressure sensor 3. Then, release the two handles 13. Under the elastic force of the two springs 12, the two locking rods 10 can be controlled to automatically slide into the corresponding slots 8 of the pins 7, thus completing the firm installation and fixation of pressure sensor 3.

[0032] When disassembling the pressure sensor 3, pull the two handles 13 to move them away from each other. The handles 13 will cause the corresponding locking rods 10 to slide out of the corresponding locking slots 8, thereby releasing the lock on the two insertion posts 7. Then the pressure sensor 3 can be pulled out upwards, thus completing the disassembly process of the pressure sensor 3. The whole process does not require complicated tools and is convenient and efficient.

[0033] After the pressure sensor 3 is installed and fixed in place, the pressure detection probe 301 at the bottom of the pressure sensor 3 can directly contact the medium inside the heat exchange station pipeline 1, enabling real-time monitoring of the internal pressure of the heat exchange station pipeline 1. The pressure data is then synchronously displayed on the display screen built into the pressure sensor 3 for easy on-site viewing by staff. The pressure sensor 3 transmits the monitored pressure data to the controller 16 inside the control box 15. The controller has a preset pressure range for normal operation of the heat exchange station pipeline. When the received pressure data exceeds this range (too high or too low), the controller 16 triggers the audible and visual alarm 17 on the top of the control box 15 to issue an alarm on-site through sound and light signals, alerting nearby staff. At the same time, it controls the wireless signal transmitter 18 to send the alarm information (including abnormal pressure value, specific pipeline location, etc.) to a remote monitoring terminal (such as a computer in the monitoring room, staff mobile phones, etc.) to achieve remote alarm. This dual alarm system, both on-site and remote, allows staff to quickly become aware of the situation and handle abnormalities in a timely manner, ensuring the safe operation of the heat exchange station.
