Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring technology, and in particular to a device for monitoring leaks in urban utility tunnel heating pipelines. Background Technology

[0002] The municipal heating pipelines entering the corridor are quite long, often branching into several lines running east, west, north, and south, each line further divided into many sections. Currently, the monitoring of these heating sections uses a combination of video surveillance and temperature / humidity monitoring, with personnel conducting regular inspections. Each section of the heating system is currently equipped with one temperature and humidity meter and one monitoring camera at each end. Since each section is mostly 200 meters long, if a leak occurs in the pipeline, the location is far from the cameras and temperature detectors, making it difficult to detect. This could lead to the following problems: 1. Failure to detect the leak in time may worsen the leak, causing greater damage to the facilities; 2. If the leak is large and not detected in time, personnel entering the area could suffer personal injury. Utility Model Content

[0003] In view of this, the present invention aims to provide a device for monitoring leaks in urban utility tunnel heating pipelines, in order to solve or alleviate the technical problems existing in the prior art.

[0004] The technical solution of this utility model embodiment is implemented as follows: a leakage monitoring device for urban pipe gallery heating pipelines includes a distributed temperature sensing optical fiber for detecting leakage in the heating pipeline body. The distributed temperature sensing optical fiber is installed close to the outer wall of the heating pipeline body, and a transmitter, a receiver and a demodulation output module are connected to the distributed temperature sensing optical fiber.

[0005] In the above embodiments: a protective layer is installed on the outer wall of the heating pipe body.

[0006] In the above embodiment: the distributed temperature-sensing optical fiber is installed close to the protective layer.

[0007] In the above embodiment: the distributed temperature-sensing optical fiber is fixed to the heating pipeline body using stainless steel cable ties.

[0008] In the above embodiment: the stainless steel cable ties are used to bundle one bundle at intervals of 3m to 4m.

[0009] In the above embodiments: the protective layer is a corrosion-resistant and heat-insulating rubber material.

[0010] In the above embodiment: an information collector is also installed on the distributed temperature-sensing optical fiber.

[0011] The present invention has the following advantages due to the adoption of the above technical solution:

[0012] This invention connects distributed temperature-sensing optical fibers to a transmitter, receiver, and demodulation output module, ensuring smooth signal transmission and processing throughout the monitoring system. Simultaneously, an information collector is installed on the distributed temperature-sensing optical fiber. This collector comprises a temperature detection sensor, an abnormal signal alarm sensor, and a signal sensor detecting the operating status of the equipment. This enhances the collection of pipeline status information, transmitting it to a display in the central control room. This facilitates problem detection by staff, enabling timely identification of the problem's location and reducing the escalation of steam leaks and the resulting facility damage. Furthermore, the information collector detects the temperature of any steam leak, allowing personnel to take appropriate protective measures during maintenance to prevent personal injury.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1-2 As shown, this utility model embodiment provides a leakage monitoring device for urban utility tunnel heating pipelines, including a distributed temperature sensing optical fiber for detecting leakage in the heating pipeline body. The distributed temperature sensing optical fiber is installed close to the outer wall of the heating pipeline body, and a transmitter, a receiver and a demodulation output module are connected to the distributed temperature sensing optical fiber.

[0024] In this embodiment, a protective layer is installed on the outer wall of the specific heating pipe body.

[0025] In this embodiment, the distributed temperature-sensing optical fiber is installed close to the protective layer.

[0026] In this embodiment, the specific distributed temperature-sensing optical fiber is fixed to the heating pipeline body using stainless steel cable ties.

[0027] In this embodiment, stainless steel cable ties are used to bundle one cable at intervals of 3m to 4m.

[0028] In this embodiment, the specific protective layer is a corrosion-resistant and heat-insulating rubber material.

[0029] In this embodiment, an information collector is also installed on the specific distributed temperature-sensing optical fiber.

[0030] In this embodiment, the specific information collection module consists of a temperature detection sensor, an alarm sensor for issuing abnormal signals, and a signal sensor for detecting the operating status of the equipment.

[0031] When this utility model is in operation:

[0032] Connecting the distributed temperature-sensing fiber optic cable to the transmitter, receiver, and demodulation output module ensures smooth signal transmission and processing throughout the monitoring system. Simultaneously, an information collector is installed on the distributed temperature-sensing fiber optic cable. This collector consists of temperature sensors, abnormal signal alarm sensors, and signal sensors that detect equipment operating status, enhancing the collection of pipeline status information. This information is transmitted to the display screen in the central control room, facilitating problem detection by staff and enabling timely location of issues. This reduces the escalation of steam leaks and minimizes potential damage to facilities. Furthermore, the information collector detects the temperature of any steam leak, allowing personnel to take appropriate protective measures during maintenance to prevent personal injury.

[0033] System operation detection

[0034] Temperature Detection: After the system is operational, the distributed temperature-sensing optical fiber continuously monitors the temperature of the outer wall of the heating pipe. Temperature sensors in the information collector constantly collect temperature information transmitted from the distributed temperature-sensing optical fiber, which is then transmitted to the transmitter.

[0035] Signal Transmission and Processing: The transmitter sends received temperature and other information signals to the receiver, which then transmits them to the demodulation output module. The demodulation output module demodulates the signals, converting them into identifiable temperature data and other status information for subsequent analysis and judgment. Simultaneously, signal sensors in the information collector monitor the operating status of the entire device in real time, ensuring normal operation.

[0036] Exception response handling

[0037] Abnormal signal triggering: When a leak occurs in the heating pipe body, the temperature at the leak point will change abnormally. The distributed temperature sensing fiber optic cable detects this temperature abnormality and transmits the signal to the abnormal signal alarm sensor in the information collector.

[0038] Alarm and Response: Upon receiving an abnormal temperature signal, the abnormal signal alarm sensor immediately issues an alarm. After receiving the alarm signal, relevant personnel can quickly locate the leak based on the specific data output by the demodulation module and take appropriate repair measures to promptly address the heating pipeline leak and ensure the normal operation of the heating system.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
