[0002] With urban development, gas pipelines are constantly being laid and extended. Gas pipelines play an important role in transporting gas, and ensuring their safe operation is extremely important. Gas valves primarily cut off and supply gas. Currently, most use PE valves, which are buried directly underground and protected by brick wells and cast iron manhole covers. Most are installed on sidewalks and are often temporarily occupied by other buildings, such as motorcycles and cars. This is especially true when gas companies are conducting joint operations, pipeline inspections, routine maintenance, or emergency rescue for sudden leaks. The valve wells that need to be operated are temporarily occupied by other buildings, such as motorcycles and cars, making it impossible to contact the vehicle owners or relevant personnel in a timely manner. This makes it impossible to open the valve wells and operate the valves, severely impacting the gas company's routine work and emergency response, and posing significant safety management risks and hidden dangers to the safe operation and management of gas.

[0016] The telescopic connection assembly 3 consists of an upper support rod 9, a lower support rod 10 and a sliding sleeve 11. The upper end of the upper support rod 9 is hinged to the first annular frame 1, and the lower end of the lower support rod 10 is hinged to the second annular frame 2. The sliding sleeve 11 is used to connect the lower end of the upper support rod 9 and the upper end of the lower support rod 10.
[0017] A fixing assembly 4 having a locking assembly passing through the second annular frame 2, the fixing assembly 4 being used to fix the warning device on the valve manhole cover; The locking assembly includes bolts and matching nuts. The bolts pass through the mounting holes of the second annular frame 2 and the preset holes of the valve well cover in sequence, and are fastened by the nuts to achieve a rigid connection between the device and the gas well.
[0018] The multifunctional warning unit is integrated on the first annular frame 2 and includes a reflective sign 5, a lighting module 6, an infrared sensing alarm module 7 and an information display board 8.
[0019] The external controller is connected to the multifunctional warning unit and is used to control and receive information from the lighting module 6 , the infrared sensing module 7 and the information display board 8 .
[0020] The infrared alarm module 7 is composed of an infrared detector 12, an audible and visual alarm 13 and a control circuit. When it detects that a human body or an object enters a preset warning range, it automatically triggers an audible and visual alarm.
[0021] The lighting module 6 is an LED warning light provided by solar energy. The light intensity of the LED warning light is adjustable and supports light-sensitive automatic start and stop.
[0022] The information display board 8 includes gas safety publicity content, facility protection signs and emergency contact numbers, and is fixed to the first annular frame 1 by a detachable buckle.

The information display board 8 is used to display important information such as gas safety publicity content, facility protection signs, and emergency contact numbers to enhance the public's safety awareness and emergency response capabilities. The external controller has a built-in smart chip that can remotely monitor and transmit data in real time to ensure the stable operation of the device.
[0024] The gas well protection and warning device of this embodiment is applied to DN300 gas valve wells along urban roads. The specific structure of the device is as follows: The first annular frame 1 and the second annular frame 2 are both welded from 20mm diameter aluminum alloy pipes. The inner diameter of the first annular frame 1 is 650mm, and the inner diameter of the second annular frame 2 is 600mm, matching the dimensions of standard gas well covers. Four telescopic connection assemblies 3 are provided, evenly distributed between the two annular frames. The upper support rod 9 and lower support rod 10 of each telescopic connection assembly 3 are both 500mm long, and the sliding sleeve 11 is a 30mm diameter aluminum alloy sleeve with a locking bolt provided on the sleeve to fix the relative position of the upper support rod 9 and the lower support rod 10.
[0025] The locking bolts for the fixing assembly 4 are stainless steel bolts, measuring 10 x 100 mm, and are secured with locknuts. Four mounting holes are evenly spaced on the second annular frame 2, with the hole spacing matching the pre-set holes on the gas manhole cover to ensure smooth bolt penetration.
[0026] The reflective sign 5 of the multifunctional warning unit is made of engineering-grade reflective film and is applied to the outer surface of the first circular frame 1. The lighting module 6 includes a 10W solar panel, a 12V / 7Ah lead-acid battery, and two 5W LED warning lights. The solar panel is mounted on the top of the first circular frame 1, and the LED lights are symmetrically arranged on both sides of the frame. The infrared sensing alarm module 7 uses an HC-SR501 infrared detector 12 and a high-decibel sound and light alarm 13. The infrared detector 12 has a detection angle of 120 degrees and an adjustable detection distance with a maximum detection distance of 5 meters. The information display board is an aluminum alloy board fixed to the front of the first circular frame 1 with a plastic clip. The board contains information on the emergency response steps for gas leaks, the gas company's customer service number, and warning slogans such as "Protecting gas facilities is everyone's responsibility."
[0027] Two symmetrical aluminum alloy portable handles are welded on the top of the first ring frame 1, and the handle surfaces are wrapped with non-slip rubber sleeves to facilitate carrying operations.
[0028] The gas well protection and warning device provided in this embodiment has the following two working states: A. Storage state: the retractable connection assembly 3 is in a retracted state, so that the first annular frame 1 and the second annular frame 2 overlap; B. Extended state: the retractable connection assembly 3 is in an extended state, so that the first annular frame 1 is lifted to form a three-dimensional protective barrier.
[0029] Based on the above gas well protection and warning device, a gas well protection and warning method is provided, which includes the following steps: S1. Open the gas well cover, pass the bolts of the fixing assembly 4 through the reserved holes in the cover and tighten; S2. Close the gas well cover and lift the first annular frame 1 to the state where the retractable assembly is fully extended; S3 activates the infrared sensing alarm module 7 and the lighting module 6 of the multifunctional warning unit; S4. Install the information display board 8 and complete the safety inspection.
[0030] It should be noted that if a gas pipeline reconstruction project requires operation on a gas well located on a sidewalk, the specific steps of using the device of the present invention are as follows: S1. Open the gas well cover. The operator places the second annular frame 2 of the device on top of the cover, aligning the bolts of the fixing assembly 4 with the pre-set holes on the cover. The operator then inserts the bolts through the mounting holes and the cover holes, screws on the nuts, and preliminarily tightens them to ensure the device is correctly positioned.
[0031] S2. Close the gas well cover. Two workers respectively hold the portable handles on the top of the first annular frame 1 and lift the first annular frame 1 upward, so that the sliding sleeve 11 of the telescopic connection assembly 3 slides upward along the lower support rod 10 until the upper support rod 9 and the lower support rod 10 are almost straight. At this time, the locking bolt on the sliding sleeve 11 automatically snaps into the preset slot, fixing the extended state of the frame, forming a three-dimensional protective barrier with a height of about 1.2 meters.
[0032] S3. The operator presses the power switch on the first ring frame 1, activating the multifunctional warning unit. This activates the infrared sensor alarm module 7, and the infrared detector 12 continuously scans the surrounding environment. The light sensor in the lighting module 6 detects ambient light. If the light is dim (such as in the evening or on a cloudy day), the LED warning light automatically illuminates. The default light intensity is set to medium, and the intensity can be adjusted using a knob.
[0033] S4. The operator secures the information display board 8 to the first ring frame 1 using snaps, ensuring the information is clearly visible. After completion, a safety inspection is conducted to check that all components are securely connected and that the warning function is functioning properly. Once all is confirmed, gas well operations begin.
[0034] During operation, if a pedestrian or vehicle approaches the gas well within approximately 3 meters, infrared detector 12 detects the infrared radiation emitted by the person or vehicle, triggering audible and visual alarm 13 to issue a voice prompt and a warning tone, "Attention, this is a gas facility area." Simultaneously, the LED brightness automatically increases to maximum to draw the attention of nearby personnel. After the operation is completed, the device is powered off, the locking bolts of the sliding sleeve are loosened, and the first ring frame 1 is pressed downward to retract the telescopic connecting assembly 3, causing the first ring frame 1 to overlap with the second ring frame 2. The bolts of the fixing assembly 4 are then removed and the device is stored for future use.
[0035] It should also be noted that the protective warning effect of the device of this embodiment in actual application is as follows: The three-dimensional protective frame effectively isolates the area surrounding the gas well, preventing pedestrians from accidentally approaching or falling into it, significantly improving safety, especially at night or during construction. The integrated use of multifunctional warning units provides all-weather, multi-dimensional warnings: reflective signs 5 reflect a clear warning signal under vehicle headlights, alerting drivers; solar-powered LED lights automatically activate at night to provide continuous illumination, ensuring the device's visibility; infrared sensor alarms 7 provide immediate audible and visual warnings when someone approaches, preventing unintentional intrusion; and information displays 8 provide clear safety instructions and emergency contact information, enhancing public safety awareness and response capabilities. The device's retractable design allows it to be stored to only one-third of its extended volume, making it easy to transport and store. Installation requires only two workers, saving labor costs. The solar power system can provide the LED lights with illumination for three consecutive nights on sunny days, eliminating the need for an external power source. It is suitable for a variety of environments and is energy-efficient and environmentally friendly. The rigid connection of the fixing assembly 4 ensures the device's stability in windy conditions, such as vehicle overrun, preventing it from shifting or tipping over.
