Description

Technical Field

[0001] The present invention relates to the technical field of safety monitoring of heating pipe networks, and in particular to an intelligent early warning hydraulic lifting sound and light alarm tower at a wellhead of a heating pipe network, an alarm method and a system. Background Art

[0002] Heating network manholes (valve wells, inspection wells, etc.) are typically located beneath urban roads or within green belts, housing critical equipment such as pipelines, valves, and compensators. Due to the enclosed environment within these manholes, combustible gases (such as methane and CO), toxic gases (such as H2S), or oxygen-deficient environments may accumulate, posing safety risks such as poisoning, explosions, and asphyxiation to inspection and maintenance personnel. Furthermore, stolen, damaged, or illegally opened manhole covers can cause pedestrians to fall and damage equipment.

[0003] Traditional wellbore safety measures have the following shortcomings: High reliance on manual inspections: Relying on regular manual testing of gas concentrations, this lacks real-time warnings and creates the risk of missed detections. Limitations of fixed alarm systems: Some wellbore-installed fixed audible and visual alarms are not high enough, easily obscured by vehicles and vegetation, resulting in poor warning effectiveness. They cannot adapt to varying wellbore depths, limiting the range of alarm signal transmission. Lack of intelligent linkage: Most alarm systems are not connected to the pipeline network monitoring center in real time, making it impossible to remotely trigger emergency responses. Summary of the Invention

[0004] The purpose of the present invention is to provide a heating network wellhead intelligent early warning hydraulic lifting sound and light alarm tower, alarm method and system, which solves the current defect of energy waste due to the asynchrony of demand between heat users and electricity users.

[0006] Preferably, the acquired monitoring data is compared with a threshold value, and whether to perform an audible or visual alarm is determined based on the comparison result. The specific method is: When the displacement is less than the first preset value, the pressure information is less than 10% of the preset pressure threshold, the temperature is greater than the first temperature threshold, or the gas concentration is greater than the first concentration threshold, a level 1 alarm prompt is issued; When the displacement is within the preset range, the pressure information is greater than or equal to 10%-50% of the preset pressure threshold, the temperature is greater than the second temperature threshold, or the gas concentration is greater than the second concentration threshold, a secondary alarm prompt is issued; When the displacement is greater than the second preset value, the pressure information is greater than or less than 50% of the preset pressure threshold, the temperature is greater than the third temperature threshold, or the gas concentration is greater than the third concentration threshold, a third-level alarm prompt will be issued.

[0007] In a second aspect, the present invention provides a heating network wellhead intelligent early warning hydraulic lifting sound and light alarm tower, comprising a base and a monitoring component, wherein a control component, a hydraulic lifting component and a sound and light alarm component are arranged in the base, wherein: The monitoring component is used to monitor the safety status of the wellhead of the heating pipe network and transmit the monitoring information to the control component; The control component is used to control the start and stop of the hydraulic lifting component and the sound and light alarm component according to the received monitoring information; The sound and light alarm component is installed on the top of the hydraulic lifting component, and its signal input end is connected to the signal output end of the control component.

[0008] Preferably, the monitoring component includes a displacement sensor, a pressure sensor, a temperature sensor and a gas sensor, wherein: The displacement sensor is a pull-rope type displacement sensor, the fixed end of which is mounted on the inner wall of the wellhead, and the free end of which is mounted on the bottom edge of the well cover, so as to collect the displacement of the well cover; The pressure sensors are arranged in plurality, and the plurality of pressure sensors are evenly distributed along the edge of the wellhead and installed on the concrete at the edge of the wellhead to collect ground pressure information around the wellhead; The temperature sensor and the gas sensor are both installed at the edge of the wellhead to collect wellhead temperature information and gas concentration.

[0009] Preferably, the hydraulic lifting assembly includes a hydraulic pump, a hydraulic cylinder and a lifting column, wherein: The output end of the hydraulic pump is connected to the input end of the hydraulic cylinder. The hydraulic cylinder is installed vertically, and its piston rod is driven and connected to the lifting column; the signal input end of the hydraulic pump is connected to the control component; the sound and light alarm component is installed at the free end of the lifting column.

[0010] Preferably, the sound and light alarm assembly includes a high-decibel speaker and a high-brightness warning light group.

[0011] Preferably, a mounting hole is opened on the ground at the edge of the wellhead of the heating pipe network, and the base is fixed in the mounting hole by bolts.

[0012] Preferably, the control component is further provided with a reset button for resetting the hydraulic lifting component and the sound and light alarm component.

[0013] Preferably, the system includes a power supply module, which is electrically connected to the control component, the monitoring component, the hydraulic lifting component and the sound and light alarm component respectively.

[0014] In a third aspect, the present invention provides a heating network wellhead intelligent early warning hydraulic lifting sound and light alarm system, based on the method described, comprising: A data acquisition unit is used to obtain real-time monitoring data of the wellhead of the heating network, including wellhead temperature, wellhead gas concentration, ground pressure around the wellhead, and displacement of the wellhead cover; The result judgment unit is used to compare the acquired monitoring data with the threshold value and determine whether to issue an audible or visual alarm based on the comparison result.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an intelligent, hydraulically-operated, acoustic and visual alarm system for heating network wellheads. This system acquires key monitoring data, such as temperature, gas concentration, ground pressure, and manhole cover displacement, in real time. This data is then dynamically compared with preset thresholds to trigger an acoustic and visual alarm, resulting in significant benefits in several areas. First, this solution enables comprehensive, real-time monitoring of heating network wellhead status. By collaboratively monitoring multiple parameters (e.g., abnormal temperatures may indicate pipeline leaks, excessive gas concentrations may indicate combustible gas accumulation, ground pressure changes may reflect soil subsidence risks, and manhole cover displacement directly impacts public safety), it significantly improves the accuracy and timeliness of identifying potential hazards, avoiding the delays and missed detections associated with traditional manual inspections. Second, the threshold-triggered acoustic and visual alarm system rapidly locates abnormal wellheads, facilitating timely intervention by maintenance personnel. This effectively shortens fault response time and reduces the risk of secondary accidents caused by monitoring delays (e.g., pipeline ruptures leading to road collapse or gas explosions). Furthermore, the technology's automated nature significantly reduces labor costs. Furthermore, the accumulated data provides a long-term basis for analyzing the health of the pipeline network, assisting in optimizing maintenance strategies. From the perspective of public safety, manhole cover displacement monitoring can prevent pedestrian falls caused by theft or displacement, while gas concentration and temperature monitoring can avoid malicious incidents such as toxic gas leakage or fire and explosion, with significant social benefits.

[0016] In summary, the present invention deeply integrates IoT technology with safety warning to form a closed-loop management of "monitoring-analysis-response", which not only improves the reliability of heating system operation, but also strengthens the intelligence level of urban infrastructure, providing key technical support for smart city construction.

[0026] There are multiple pressure sensors, which are evenly distributed along the edge of the wellhead and installed on the concrete at the edge of the wellhead to form a ring monitoring network for collecting ground pressure information around the wellhead.

[0027] The temperature sensor and the gas sensor are both installed at the edge of the wellhead to collect wellhead temperature information and gas concentration.

[0041] Example 7 This embodiment provides a heating network wellhead intelligent early warning hydraulic lifting sound and light alarm method, which is characterized by comprising the following steps: Real-time acquisition of monitoring data from the wellhead of the heating network, including wellhead temperature, gas concentration, ground pressure around the wellhead, and displacement of the wellhead cover; The acquired monitoring data is compared with the threshold value, and an audible and visual alarm is issued according to the comparison result, where: When the displacement is less than the first preset value, the pressure information is less than 10% of the preset pressure threshold, the temperature is greater than the first temperature threshold, or the gas concentration is greater than the first concentration threshold, a level 1 alarm prompt is issued; When the displacement is within the preset range, the pressure information is greater than or equal to 10%-50% of the preset pressure threshold, the temperature is greater than the second temperature threshold, or the gas concentration is greater than the second concentration threshold, a secondary alarm prompt is issued; When the displacement is greater than the second preset value, the pressure information is greater than or less than 50% of the preset pressure threshold, the temperature is greater than the third temperature threshold, or the gas concentration is greater than the third concentration threshold, a third-level alarm prompt will be issued.

[0042] In this embodiment, real-time acquisition of key monitoring data, such as temperature, gas concentration, ground pressure, and manhole cover displacement, at the wellheads of the heating network is dynamically compared against preset thresholds to trigger audible and visual alarms, resulting in significant benefits in several areas. First, this solution enables comprehensive, real-time monitoring of the wellhead status of the heating network. By collaboratively monitoring multiple parameters (e.g., abnormal temperatures may indicate pipeline leaks, excessive gas concentrations may indicate combustible gas accumulation, ground pressure changes may reflect soil subsidence risks, and manhole cover displacement directly impacts public safety), it significantly improves the accuracy and timeliness of identifying potential hazards, avoiding the lag and risk of missed inspections associated with traditional manual inspections.
