Description

Technical Field

[0001] The present invention relates to the technical field of live working on power transmission lines, and in particular to a smart oxygen supply and micro-meteorological monitoring live working hanging basket and method suitable for high altitude areas. Background Art

[0002] In contemporary society, with the rapid development of science and technology, electricity, as a clean and efficient energy source, plays an indispensable role in modern society. Whether in industrial production or daily life, the widespread use of electricity provides a strong driving force for the progress of human society. It is crucial to ensure the stability and reliability of electricity supply, and the safe operation of transmission lines, as an important carrier of electricity transmission, is directly related to the quality and efficiency of electricity supply. However, for transmission lines located in remote mountainous areas or high-altitude areas, these places often have harsh natural environments and complex climatic conditions. Especially in high-altitude areas, transmission lines not only have to face harsh natural conditions, but also have to cope with the challenges brought by live-line operations. In live-line operations on transmission lines in high-altitude areas, hypoxia is one of the major problems. Due to the special environment in high-altitude areas, workers need to face an extremely low oxygen environment when performing live-line operations, which is undoubtedly a huge challenge for live-line operators who perform physical labor. In addition, micro-meteorological phenomena unique to high-altitude areas, such as rapidly changing wind speeds, temperature fluctuations, humidity changes, and fluctuations in air dust content, will also affect the health and safety of operators. The rapid changes in these micro-meteorological conditions are often difficult to accurately predict through conventional weather forecasts, which increases the uncertainty and risk of operations. They are mainly manifested in the following aspects: (1) Reduced work efficiency: In high-altitude areas, the hypoxic environment will cause the workers to consume more energy faster. After long-term work, the work efficiency will drop significantly, which will extend the time to complete the given task. (2) Increased difficulty in implementing safety protection measures: Due to hypoxia, workers may feel overwhelmed when implementing safety protection measures, such as wearing protective equipment correctly and following safety operating procedures. The difficulty of implementing these measures increases, thereby increasing the risk of operations. (3) Weakened perception of the working environment: Hypoxia may weaken the workers' ability to perceive the surrounding environment, such as reduced sensitivity to voltage and current, and reduced ability to identify potential dangers at the work site, which may lead to neglect of safety risks. (4) Reduced emergency response ability: In the hypoxic state, the workers' emergency response ability in the face of emergencies will be affected, such as rapid evacuation and emergency power outages. This reduced ability may lead to serious consequences at critical moments. (5) Micrometeorological influences: Micrometeorological phenomena in high altitude areas, such as sudden strong winds, sudden drops in temperature, changes in humidity and increased dust content, may pose additional risks to the health and safety of workers.

[0012] The present invention also discloses a method for using the above-mentioned smart oxygen supply and micro-meteorological monitoring type live working hanging basket suitable for high altitude areas, which comprises the following steps: Step 1, preparation stage: pass the lifting rope through the lifting rope hole above the main frame to ensure that the lifting rope is firmly fixed to maintain the stability of the entire hanging basket during the lifting process; Step 2: Install and fix the oxygen tank: Loosen the claw-type fixing clip on the oxygen tank fixing device, put the compressed oxygen tank into the claw-type fixing clip, make sure the compressed oxygen tank is correctly placed and centered, then rotate the wheel handle to drive the screw to rotate. Since the bottom of the two mobile bases cooperate with the front and rear threads of the screw, and the external threads of the front and rear sides of the screw are in opposite directions, the two mobile bases can be close to each other so that the two claw-type fixing clips clamp the compressed oxygen tank, ensuring the stability and safety of the compressed oxygen tank in the hanging basket; Step 3: Connect the oxygen supply system: Align and connect the compressed oxygen tank’s gas pipe with the oxygen tank support’s oxygen transport pipe to ensure that oxygen can be smoothly transported from the compressed oxygen tank to the operator.

Step 4: Safety check of oxygen tank support device: Close the door of the oxygen tank support device to ensure the safety of oxygen supply, check the tightness of the oxygen tank support device to ensure there is no risk of oxygen leakage; Step 5: Prepare tools and equipment. Place the tools and necessities required for live work in the storage slots on the main frame to ensure that the operators can easily access them. Step 6. Worker entry and basket closure: Workers wear personal protective equipment, enter the basket, and ensure that safety equipment such as safety belts are fully worn. Start the physiological signal detection device worn on the wrist of the live working worker, and start the central processor at the same time. During the live working process, it will continue to process physiological signals; the specific processing method of the physiological signals of the live working workers in the high-altitude areas at each sampling time during the working process is as follows: The surface temperature of the human body at each sampling time during live working , arterial systolic pressure and diastolic blood pressure Substitute the following formula: ; Get the first physiological information safety factor of live working personnel ,in It indicates the standard body surface temperature of the worker when not working in high altitude areas, which is stored in the database. , They represent the maximum value of the arterial standard systolic pressure and the maximum value of the arterial standard diastolic pressure during the preset live line operation. , They represent the preset body surface temperature deviation value and the weight factor of the arterial systolic pressure change during live working. represents the correction factor; The determining factors of the physiological signals of the human body at high altitudes are blood oxygen saturation and heart rate increase. , heart rate increase times and the altitude of the work site Substitute the following formula: ; Get the second physiological information safety factor of live working personnel ,in It indicates the standard blood oxygen saturation that can ensure normal operation of the workers during live working. express The corresponding standard altitude is Indicates the standard heart rate of workers working with live wires. , They represent the weight factors of the deviation values ​​of blood oxygen saturation and heart rate increase times during the preset live working process, represents the correction factor; The physiological information safety factor of live-line workers and Substituting into the formula: ; Obtaining the operational safety index of physiological signals of live line workers in high altitude areas ,in and They represent the weights of the secondary physiological factors and the decisive physiological factors of the preset high-altitude live-line workers respectively; The operation safety index of the physiological signal of the live-line workers in high altitude areas is compared with the preset reference range of the operation safety index of the physiological signal of the live-line workers in high altitude areas.

After confirming that all equipment and safety measures are ready, the helicopter starts and carries the hanging basket to the wire where live work is required. After being placed at the work site, the operator can start live work. During the operation, the physiological signal detection device worn on the operator's wrist continuously monitors the physiological signals of the live worker, sends the real-time physiological signals to the central processor, and makes safety judgments on the personnel's physical information. The oxygen supply should be continuously monitored and the oxygen flow rate should be adjusted as needed. The micro-meteorological detection device on the hanging basket collects key meteorological parameters such as wind speed, temperature, humidity, and air dust content in real time. The central processor will conduct real-time meteorological analysis and forecasting on these data: after collecting relevant parameters in the air, they will be transmitted to the central processor for logical judgment, and the wind speed, humidity, air pressure and probability of rain will be given. If meteorological conditions that may affect the operation are detected, such as strong winds, rapid temperature changes or high humidity, and combined with the operator's visual judgment, the processor will promptly issue an early warning signal to remind the operator to take preventive measures, including suspending the operation, taking measures to avoid rain, and dispatching helicopters in time to safely send the operator to the ground to ensure the continuity and safety of the operation; The specific process of the central processor performing real-time meteorological analysis and forecasting on the data is as follows: The meteorological parameters collected by the oxygen supply basket at the work site, including air humidity , atmospheric pressure and wind speed at the work site Substituting into the formula: ; Obtain the meteorological risk factor for live line work in high altitude areas ,in It represents the correction factor of the working meteorological risk factor for live line work in high altitude areas, where Indicates the standard value of rainfall air humidity, Indicates the allowable deviation of air humidity when raining conditions are reached.

Finishing work after the operation is completed. After the operation is completed, the operator should turn off the oxygen supply and central processing unit, pack up the tools, and ensure that all equipment and tools have been safely stored or removed; then, safely evacuate the basket and perform necessary equipment inspection and maintenance.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1-4 As shown, a smart oxygen supply and micro-meteorological monitoring type live working hanging basket suitable for high altitude areas includes a manned chassis 8, and the manned chassis 8 is vertically provided with supporting columns 7 around it. The side of the supporting column 7 is fixed with an oxygen tank supporting device 4, and the oxygen tank supporting device 4 is provided with an oxygen tank fixing device 5 inside. A compressed oxygen tank 6 is arranged inside the oxygen tank fixing device 5, and a rope through hole 1 that cooperates with the hanging rope is provided on the top of the supporting column 7. In this embodiment, the four supporting columns are all made of high-strength steel to ensure the structural strength and stability of the overall frame of the hanging basket, and the manned chassis is connected to the four supporting columns by welding. Between the two supports on the working side, five groups of anti-fall railings are welded. These railings are arranged equidistantly, which not only provides additional safety protection, but also enhances the lateral stability of the hanging basket. Four rope through holes are welded at the four corners of the top of the hanging basket above the supporting columns. The precise position and size of these through holes ensure the balance and safety of the hanging basket during the hoisting process.

[0027] Preferably, anti-fall welding plates 3 are fixed on both sides of the manned chassis 8, and anti-fall railings 2 are fixed on the sides of the support columns 7. The anti-fall welding plates are composed of two grid-shaped steel plates, which are located on the left and right sides of the manned bottom plate of the manned hanging basket body and can be closed after people enter to prevent the operators from falling.

[0028] Preferably, it also includes a central processing unit, the signal input end of the central processing unit is connected to the output ends of the physiological signal detection device and the micro-meteorological detection device respectively, and the signal output end of the central processing unit is connected to the alarm.

[0029] Preferably, the oxygen tank supporting device 4 includes a main frame 4.1 fixed to the side of the supporting column 7, an oxygen transport pipe 4.2 matched with the compressed oxygen tank 6 is provided on the main frame 4.1, a notch matched with the oxygen tank fixing device 5 is provided at the end of the main frame 4.1, and an oxygen supply electric regulating valve is provided at the valve port of the compressed oxygen tank 6. In this embodiment, the oxygen transport pipe can transport oxygen from the inside of the supporting device to the back of the device, ensuring that the operator can also obtain a stable oxygen supply at high altitude. A pre-opened notch is also provided in the main frame of the device for the installation of the oxygen tank fixing device. Baffles are welded on both sides to prevent foreign debris from entering the inside of the device. The front side is the entrance of the oxygen tank, equipped with a closable small door, which is closed after the oxygen tank is placed and fixed. The rear side is designed as a sealing structure to further improve the safety of the oxygen supply. A storage slot is also designed above the main frame of the device to facilitate the operator to store live working tools and other necessities. The oxygen supply electric regulating valve provided at the valve port of the compressed oxygen tank 6 can be controlled by a central processor and can adjust the flow in real time.

[0030] Preferably, the oxygen tank fixing device 5 includes two movable bases 5.1 located at the front and rear sides, the bottoms of the two movable bases 5.1 are threadedly matched with the front and rear sides of the screw rod 5.2, the external threads of the front and rear sides of the screw rod 5.2 are in opposite directions, one end of the screw rod 5.2 is rotatably connected to the main frame 4.1 through a bearing, and the other end is fixedly connected to the wheel handle 5.3, and a claw-type fixing clamp 5.4 is provided on the top of the movable base 5.1 to match the surface of the compressed oxygen tank 6.

Since the bottoms of the two movable bases 5.1 are threadedly matched with the front and rear sides of the screw rod 5.2, and the external threads of the front and rear sides of the screw rod 5.2 are in opposite directions, the two movable bases 5.1 can be close to or separated from each other, making the fixing and disassembly process of the compressed oxygen tank 6 simpler and safer.

[0031] The present invention also discloses a monitoring method for the above-mentioned intelligent oxygen supply and micro-meteorological monitoring type live working hanging basket applicable to high altitude areas, which comprises the following steps: Step 1: The central processor receives in real time the physiological signals detected by the physiological signal detection device carried by the operator; the physiological signals include but are not limited to key physiological parameters such as heart rate, blood pressure, and blood oxygen. These parameters are crucial for assessing the health status of operators when performing live-line work in high-altitude areas, because the low oxygen environment in high-altitude areas will have a significant impact on these physiological factors. The physiological signal detection device can be a smart bracelet, and the physiological signals detected by it include but are not limited to key physiological parameters such as heart rate, blood pressure, and blood oxygen.

[0032] Step 2: The central processor analyzes the received physiological signals in real time, evaluates the life safety of the operator, determines whether there is an operational risk based on the changes in the operator's physiological parameters, sets a safety threshold range, and issues an alarm when necessary, prompting the operator or the ground control center to take corresponding safety measures; Step 3: The central processor receives the meteorological information collected by the micro-meteorological detection device in real time; the meteorological information includes key meteorological parameters such as air pressure, wind speed, temperature, humidity, wind direction, rainfall and air dust content. These parameters are crucial for predicting and evaluating micro-meteorological phenomena unique to high-altitude areas. Climate change in high-altitude areas is fast, and conventional weather forecasts are often difficult to accurately predict.

[0033] Step 4: The central processing unit conducts real-time meteorological analysis and rainfall warning based on the data provided by the micro-meteorological detection device and the micro-meteorological methods unique to high-altitude areas; when meteorological conditions that may affect live operations are detected, the processor will promptly issue a warning signal to remind operators to take preventive measures, such as suspending operations, taking rain shelter measures, etc., to ensure operational safety.

[0034] Step 5: The central processor transmits the real-time analyzed physiological signals and meteorological information to the ground control center synchronously, so that the ground control personnel can monitor the health status of the workers and the meteorological conditions of the working environment in real time, and provide decision support for the ground control center. This real-time data sharing mechanism not only improves the safety of the operation, but also provides decision support for the ground control center, making it faster and more effective to respond to emergencies.

[0035] Furthermore, the specific process of step 2 is as follows: Step 2.1, real-time data reception: real-time reception of physiological signals from the wristband of the live worker, including the worker's real-time blood oxygen saturation, blood pressure, body temperature and heart rate.

[0036] Step 2.2: Signal analysis and evaluation: Analyze the received physiological signals and compare them with the built-in normal physiological signal value range database to evaluate the physiological status of the operator.

[0037] Step 2.3: Judgment logic of normal range of physiological parameters: Condition (1): Blood oxygen saturation will decrease in high altitude environment, and the average blood oxygen saturation must be greater than or equal to 85%, and the minimum blood oxygen saturation must be greater than 75%; Condition (2): Blood pressure will change in high altitude areas, requiring systolic blood pressure to be lower than 120 mmHg and diastolic blood pressure to be lower than 100 mmHg; Condition (3): In high altitude areas, human body temperature is greater than 36.3℃ to maintain normal body temperature; Condition (4): Heart rate will increase due to the body's response to hypoxia, the normal increase range is 20 beats / minute, and the maximum heart rate is required to be less than 140 beats per minute; Step 2.4: Warning trigger logic: Condition (1): When the method detects that the blood oxygen saturation is lower than 85% or the lowest value is lower than 75%, or the blood pressure is outside the normal range, or the body temperature is lower than 36.3℃, or the heart rate is outside the normal range; Condition (2): Within the expected delay time of 20 seconds, if any abnormal signal in condition (1) persists, the operator's physiological signal is judged to be abnormal.

[0038] Step 2.5: Early warning: When conditions (1) and (2) are met, the early warning mechanism will be triggered, an alarm will be issued to the operator, and the on-site safety manager will be notified. The above steps can monitor the physiological status of the operator in real time, detect and warn of potential health risks in a timely manner, and thus ensure the safety of the operators working with live wires.

[0039] Furthermore, the specific process of step 4 is as follows: Step 4.1: Real-time data reception: The micro-meteorological data of the high-altitude working environment is collected in real time through the micro-meteorological detection device, including temperature, humidity, wind speed, air pressure and UV index; Step 4.2: Signal analysis and evaluation: Conduct in-depth analysis of the collected micro-meteorological data and compare it with the preset normal climate parameter range to evaluate the safety of the working environment; Step 4.3: Judgment logic of the normal range of climate parameters: Condition (1): In high-altitude areas, the temperature will change rapidly. It is necessary to ensure that the real-time temperature is not lower than 5°C to prevent workers from being harmed by low temperatures; Condition (2): The humidity must be maintained between 30% and 70% to ensure the comfort of workers and reduce the harm of static electricity; Condition (3): Wind speeds exceeding 20 m / s will cause danger to operations. It is necessary to monitor wind speeds and assess potential risks; Condition (4): The reduction in air pressure will affect human comfort and health. It is necessary to ensure that the air pressure is not lower than 550 hPa, and when the air pressure drops rapidly, there will be a risk of rainfall; Condition (5): When the UV index exceeds 7, workers need to take additional protective measures and monitor the UV intensity in real time; Step 4.4: Warning trigger logic: Condition (1): When the method detects that the temperature is lower than 5°C, or the humidity is outside the range of 30% to 70%, or the wind speed exceeds 20 m / s, or the air pressure is lower than 550 hPa, or the UV index exceeds 7; Condition (2): Within the expected delay time of 30 seconds, if any of the abnormal climate parameters in condition (1) persists, it is judged that there is a potential risk in the working environment; Step 4.5: Warning is issued.
