Description
Technical Field
[0001] The invention relates to a conical safety protection device for a pile foundation hole and a use method thereof, belonging to the technical field of safety protection. Background Art
[0002] During the construction of urban pile foundations, there are safety hazards such as collapse, falling and intrusion of foreign objects at the pile foundation holes. Especially in severe weather such as heavy fog, heavy rain and strong winds, traditional physical isolation facilities are difficult to effectively warn pedestrians and vehicles, and accidents of accidental entry occur frequently.
[0003] Existing technologies often use fixed fences or simple warning tape to protect pile openings. These structures are non-adjustable and unable to adapt to the protection needs of varying weather conditions. For example, traditional warning lights lack penetration in foggy weather, dangerous protection structures become unstable during heavy rain, and equipment easily overturns in strong winds. As a result, traditional protection equipment lacks dynamic environmental adaptability and multimodal collaborative response mechanisms. Consequently, in adverse weather conditions such as heavy fog, heavy rain, and strong winds, it is unable to simultaneously achieve physical isolation stability, energy supply reliability, and pedestrian / vehicle warning effectiveness. This ultimately creates a vicious cycle of environmental degradation, protection failure, and safety accidents.
[0004] Therefore, the purpose of this study is to design a pile foundation hole protection device that can solve the problems of poor adaptability in severe weather, strong energy dependence, single warning means and lack of emergency response capabilities. Summary of the Invention

The control module controls the warning light group to dynamically adjust the switch of the warning light beam according to the change of environmental visibility. The control module controls the second driving component to adjust the depth of the second support rod into the ground according to the change of environmental vibration intensity.
[0007] As a further improvement, the power generation safety barrier assembly further includes a protective net surrounding and covering the conical support structure, and the solar photovoltaic power generation assembly is fixedly mounted on the protective net; The protective net is made of high-strength PE woven mesh with a nano-hydrophobic coating on the surface, and is detachably connected to the support rod group of the conical support structure through metal buckles.
[0008] As a further improvement, the solar photovoltaic power generation assembly includes a plurality of photovoltaic sheets connected in series through a flexible circuit board to form a photovoltaic network, and the photovoltaic sheets are embedded in the surface of the protective net; The surface of the photovoltaic sheet is covered with a scratch-resistant transparent film layer.

[0009] As a further improvement, the solar photovoltaic power generation assembly includes a photovoltaic solar panel, and the photovoltaic solar panel is fixedly connected to the support rod through a metal clip.
[0010] As a further improvement, the environmental monitoring component includes a visibility sensor, specifically a laser scattering sensor, which is installed on the top of the warning component and has a detection range of 0-10m; The vibration sensor is specifically an acceleration sensor, which is suspended and installed below the protective net in the middle of the second support pole to detect the vibration intensity threshold; The proximity sensor is specifically a millimeter wave radar, which is installed on the first support pole outside the conical support structure to detect moving objects within a meter and distinguish between people and vehicles.
[0011] The first driving assembly includes an electric telescopic guide rod, the bottom of which is fixed to the second driving assembly; The output end of the electric telescopic guide rod is connected to the top end of the first support rod through a hinge, which can achieve ±5° angle adjustment; The limit switch is arranged inside the electric telescopic guide rod, and the control module controls the telescopic speed and stroke of the electric telescopic guide rod through a PWM signal.
[0012] As a further improvement, the second drive assembly includes a servo motor, one end of which is fixed to the bottom of the electric telescopic guide rod by welding, and a handle is provided on the outside of the servo motor, and the connecting member passes through the handle to position and connect the multiple servo motors; One end of the second support rod is inserted into the output end of the servo motor, and the other end of the second support rod is a threaded tip; The control module adjusts the insertion depth into the ground through a closed-loop PID algorithm.

S4: The proximity sensor identifies the approach of a person or vehicle, turns on the projection light group to form a hazard projection warning around the perimeter, and uses the sound module to provide a secondary warning; S5, the impact sensor identifies a person / vehicle collision, and the second driving assembly drives the second support rod further into the ground to strengthen the fastening force.
[0016] The beneficial effects of the present invention are: This invention achieves a systematic solution to the problem of pile foundation opening protection in severe weather through a five-step closed-loop system: environmental perception - dynamic regulation - energy security - graded warnings - and accident response. Specifically, environmental perception collects multi-dimensional environmental data in real time, triggering an early warning mechanism. A visibility sensor monitors atmospheric transparency using laser scattering, a 24GHz millimeter-wave radar scans pedestrian and vehicle trajectories within 10 meters, a vibration sensor detects ground impact signals, and an anemometer records real-time wind speed.
[0017] Through a multi-sensor network, the limitations of traditional passive perception are broken, and risks such as heavy fog visibility <50m, heavy rain humidity >90%, and strong wind >15m / s are identified in advance, providing data input for dynamic adjustment.
[0018] The environmental data collection frequency reaches 1Hz, and the response delay is less than 1 second, ensuring timely early warning.
[0019] The height of the first support rod is adjusted by dynamically adjusting the support rod group in linkage with the first drive assembly to ensure that the top ends are in the same horizontal plane; The second driving assembly rotates the second support rod to a depth where it is inserted into the ground, and the hydraulic buffer absorbs stress caused by uneven ground.
[0020] In heavy fog mode, the height of the first pole can be raised to expand the coverage of the warning component. In heavy rain mode, the height of the first pole can be shortened to tilt the protection net and increase the drainage speed. In strong wind mode, the second pole can be deepened and inserted into the ground by a maximum of 15 cm to enhance the anti-overturning ability.
[0021] Through solar power generation, photovoltaic panels are embedded in the surface of the protective net, flexible circuit boards are connected in series to form a photovoltaic network, and inverters convert direct current into power supply for equipment; The energy storage system works in conjunction with a hydrogen fuel cell through a graphene supercapacitor with a capacity of 500F to prioritize power supply for warning lights and sensors.
[0022] Eliminate energy dependence and power outage risks. In normal mode, solar power is prioritized, with battery charging efficiency exceeding 95%. In emergency mode, non-core loads such as projector lamps are disconnected. The hydrogen fuel cell provides a 120-hour battery life. Core functions remain operational for 72 hours in severe weather, with power recovery time of less than 5 seconds.
[0023] Multi-modal output with graded warnings addresses diverse needs. The laser light module features a 520nm green light with a 10° divergence angle for smoke penetration; the strobe light module features a 6500K color temperature LED with a 2Hz high-frequency flash; the projector module features a DLP module for projecting escape arrows with SVGA resolution; and the sound module features a directional speaker for outputting voice alerts. This eliminates the disconnect between single warning modes and dynamic threats.
[0024] In heavy fog mode, the system uses lasers and voice alerts, such as "Danger ahead, please detour." In heavy rain mode, it uses flashing lights and voice alerts, such as "Danger ahead, please detour." In strong wind mode, the system disables the laser light assembly to prevent beam jitter from disturbing the driver. With a laser penetration of up to 200 meters, the pedestrian error rate is reduced by 92% and the vehicle error rate by 85%.
[0025] When a collision occurs and the vibration sensor detects an impact intensity greater than 5g, the sound module plays a siren sound, the servo motor drives the second support rod deep into the ground and fixes it, and an alarm is sent through the municipal platform; In case of power outage emergency, when the energy storage battery voltage is less than 10.5V, the hydrogen fuel cell backup power supply is started and the laser light group switches to low power mode with a power of 20W.
[0026] This solution addresses delayed emergency response and amplified accidents, with structural reinforcement response times of less than 0.5 seconds, remote alarm delays of less than 3 seconds, and core functionality maintained for more than 72 hours after a power outage. Through a comprehensive sensor-drive-energy-alarm linkage, this system breaks the vicious cycle of traditional equipment. This system offers strong adaptability to severe weather, low energy dependency, multiple warning methods, and emergency response capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.
[0039] Example 1 Reference Figure 1-8 As shown; A conical safety protection device for a pile foundation opening, comprising: a plurality of support rods 1 forming a conical support structure around the pile foundation opening, a plurality of longitudinally distributed connectors for connecting the plurality of support rods, a sleeve 3 sleeved over the conical support structure, a warning assembly located above the sleeve 3, a power generation safety screen assembly covering the conical support structure, and a control module 4; The support rod assembly 1 includes a first support rod 11 located at the top, a second support rod 12 located at the bottom, and an adjustment assembly connecting the first support rod 11 and the second support rod 12. The adjustment assembly includes a first drive assembly 13 for controlling the extension and retraction of the first support rod 11 and a second drive assembly 14 for controlling the rotation of the second support rod 12. The warning component includes a warning light group 5, and the power generation safety barrier component includes a solar photovoltaic power generation component 6, which is used to collect, convert, store and supply solar energy; It also includes an environmental monitoring component 7, and the control module 4 is electrically connected to the first drive component 13, the second drive component 14, the warning light group 5, the solar photovoltaic power generation component 6, and the environmental monitoring component 7; The control module 4 cooperates with the first drive assembly 13 to adjust the tops of the first support rods 11 in the different support rod groups 1 to the same height, and a mounting portion is formed above the plurality of first support rods, which is mounted in cooperation with the sleeve plate 3 through the mounting portion; The environmental data is fed back to the control module 4 through the environmental monitoring component 7, and the environmental data includes visibility and vibration intensity. The control module 4 controls the warning light group 5 to dynamically adjust the switch of the warning light beam according to the change of environmental visibility. The control module 4 controls the second driving component 14 to adjust the depth of the second support rod 12 into the ground according to the change of environmental vibration intensity.
[0040] Through a five-step closed-loop system consisting of environmental perception, dynamic regulation, energy security, graded warnings, and accident response, a systematic solution is achieved for pile foundation opening protection in severe weather. Specifically, environmental perception collects multi-dimensional environmental data in real time, triggering an early warning mechanism. Visibility sensors monitor atmospheric transparency using a 71-degree laser scattering sensor, a 7324GHz millimeter-wave radar scans pedestrian and vehicle trajectories within a 10-meter radius, a vibration sensor detects ground impact signals, and an anemometer records real-time wind speeds.
[0041] Through a multi-sensor network, the limitations of traditional passive perception are broken, and risks such as heavy fog visibility <50m, heavy rain humidity >90%, and strong wind >15m / s are identified in advance, providing data input for dynamic adjustment.
[0042] The environmental data collection frequency reaches 1Hz, and the response delay is less than 1 second, ensuring timely early warning.
[0043] The height of the first support rod 11 is adjusted by dynamically adjusting the support rod group 1 in conjunction with the first driving assembly 13 to ensure that the top ends are at the same horizontal plane; The second driving assembly 14 rotates the second support rod 12 to a depth that allows the second support rod 12 to be inserted into the ground, and the hydraulic buffer absorbs stress caused by uneven ground.
[0044] In heavy fog mode, the height of the first support pole 11 can be increased to expand the coverage of the warning component. In heavy rain mode, the height of the first support pole 11 can be shortened to tilt the protective net 8 and accelerate drainage. In strong wind mode, the second support pole 12 can be deepened and inserted into the ground by a maximum of 15 cm to enhance anti-overturning ability.
[0045] Through solar power generation, photovoltaic sheets 61 are embedded in the surface of the protective net 8, and flexible circuit boards are connected in series to form a photovoltaic network. The inverter converts DC power into power supply for the equipment; The energy storage system works in conjunction with a hydrogen fuel cell through a graphene supercapacitor with a capacity of 500F to prioritize power supply for the warning light group 5 and sensors.
[0046] This solution addresses energy dependency and power outage risks. In normal mode, solar power is prioritized, with battery charging efficiency exceeding 95%. In emergency mode, non-core loads, such as the projector light cluster, are disconnected. The hydrogen fuel cell provides a 120-hour battery life. Core functions remain operational for 72 hours in severe weather, with power recovery time of less than 5 seconds.
[0047] Multi-modal outputs with graded warnings address diverse needs. These include a laser light module with a 525nm green beam for smoke penetration and a 10° divergence angle; a 536500K color temperature LED flash module with a high-frequency flash of 2Hz; a 54DLP projection module for projecting escape arrows with SVGA resolution; and a 55 directional speaker module for outputting voice alerts. This eliminates the disconnect between single warning modes and dynamic threats.
[0048] In heavy fog mode, the system uses lasers and voice alerts, such as "Danger ahead, please detour." In heavy rain mode, it uses flashing lights and voice alerts, such as "Danger ahead, please detour." In strong wind mode, the system disables the laser light assembly 52 to prevent beam jitter from disturbing the driver. With a laser penetration of up to 200 meters, the pedestrian error rate is reduced by 92% and the vehicle error rate by 85%.
[0049] When a collision occurs and the vibration sensor detects an impact intensity greater than 5g, the sound module 55 plays a siren sound, the servo motor 141 drives the second support rod 12 to penetrate the ground and fix it, and an alarm is issued through the municipal platform; In case of power outage emergency, when the energy storage battery voltage is less than 10.5V, the hydrogen fuel cell is started to provide backup power, and the laser light group 52 switches to a low power consumption mode of 20W.
[0050] To solve the problem of delayed emergency response and accident amplification, the structural reinforcement response time is <0.5 seconds, the remote alarm delay is <3 seconds, and the core function maintenance time after power outage is >72 hours.
[0051] By linking the entire chain of sensors, drives, energy and warnings, we can break the vicious cycle of traditional equipment.
[0052] Traditional protective nets 8 are mostly made of ordinary plastic or metal, which have problems such as low tensile strength, such as easy breakage of plastic, or easy corrosion, such as rusting of metal. They are difficult to withstand mechanical impact and severe weather erosion in pile foundation construction scenarios. The power generation safety barrier assembly also includes a protective net 8 surrounding and covering the conical support structure, and the solar photovoltaic power generation assembly 6 is fixedly mounted on the protective net 8; The protective net 8 is made of high-strength PE woven net, the surface of which is coated with a nano-hydrophobic coating 81 and is detachably connected to the support rod group 1 of the conical support structure through a metal buckle 82.
[0053] The high-strength PE polyethylene woven mesh has excellent tensile properties with a tensile strength of >30MPa, which can withstand external impacts such as strong winds and heavy rains. At the same time, it is light and flexible, making it easy to quickly deploy and recycle.
[0054] The traditional protective net 8 is easy to be dangerous or absorb dust in heavy rain or foggy weather, resulting in reduced light transmittance, increased deadweight and even structural failure.
[0055] The nano-hydrophobic coating 81, such as a silica / fluorosilane composite material, reduces the surface energy so that the contact angle between water droplets and pollutants is greater than 150°, thereby achieving a self-cleaning function and reducing the impact of rainwater penetration on the strength of the protective net 8.
[0056] The metal clip 82, such as a 304 stainless steel cable tie + plastic clip combination, provides a quick disassembly and assembly capability, supports the individual replacement of a partially damaged mesh, and at the same time enhances the connection stability through the bite design of the clip and the support rod group 1.
[0057] The high-strength PE woven mesh has a tensile strength of more than 30MPa and can withstand the impact of wind speed and pressure of level 10>250Pa, preventing the protective net 8 from tearing or deformation; The nano-hydrophobic coating 81 reduces the increase in mesh weight caused by rainwater penetration, with a measured water permeability of <5%, reducing the load on the supporting structure and preventing the risk of hole collapse caused by danger.
[0058] In actual foggy weather tests, the nano-hydrophobic coating 81 maintained 80% light transmittance on the protective net 8, laser warning penetration reached 200 meters, and the pedestrian error rate decreased by 92%. The rainstorm scenario verification showed that the drainage rate of the protective net 8 increased by 40%, and the equipment overturning rate was less than 0.1%; Compared with the traditional single-piece network replacement time of 15 minutes, it is shortened to 30 seconds, and the maintenance cost is reduced by 70%.
[0059] Traditional photovoltaic modules use rigid substrates such as glass or aluminum, which are difficult to adapt to the curved surface structure of the conical protective net 8. Deformation can easily lead to circuit breakage or reduced power generation efficiency. The solar photovoltaic power generation module 6 includes multiple photovoltaic panels 61 connected in series through a flexible circuit board to form a photovoltaic network. The photovoltaic panels 61 are embedded in the surface of the protective net 8. The surface of the photovoltaic sheet 61 is covered with a scratch-resistant transparent film layer 62. The inverter and energy storage battery are integrated into the inner part of the cover plate 3 and are electrically connected to the photovoltaic network through wires.
[0060] By using a flexible circuit board such as a polyimide substrate with a bendable property and a bending radius of <5mm, it can fit the curved surface of the conical protective net 8, ensuring that the photovoltaic panel 61 maintains circuit connectivity during dynamic adjustments such as pole extension / rotation, while reducing power loss caused by local obstructions such as dust and raindrops.
[0061] Traditional photovoltaic modules require additional mounting brackets, which increases the size and weight of the equipment and is prone to conflict with the protective net 8, such as blocking the warning light beam.
[0062] By directly embedding the photovoltaic sheet 61 into the surface of the protective net 8 and using the PE woven structure of the protective net 8 as a supporting carrier, an integrated protection-power generation design is achieved, which reduces space occupation and avoids blocking warning components.
[0063] The surface of the photovoltaic panel 61 is susceptible to friction from gravel, impact from hail, or chemical corrosion such as acid rain, which results in a decrease in light transmittance. The light transmittance of traditional glass surfaces decreases by >10% per year.
[0064] By setting up a scratch-resistant transparent film layer 62 such as a diamond-like carbon film or a titanium oxide / silicon dioxide composite coating with a nano-hardness of >20GPa and a high transmittance of >92%, the photovoltaic panel 61 is protected from physical damage, while reducing the adhesion of stains and maintaining long-term power generation efficiency.
[0065] Since traditional photovoltaic systems require external inverters and energy storage modules, they increase equipment complexity and maintenance difficulty, and are easily eroded by rainwater.
[0066] By integrating the inverter MPPT controller and the energy storage battery graphene supercapacitor inside the cover plate 3, using the IP67 grade waterproof structure of the cover plate 3 to protect the electronic components, and directly connecting it to the photovoltaic network through wires, the power transmission loss is reduced to <3%.
[0067] The photovoltaic panel 61 can dynamically adjust the inclination angle of 0°-30° along with the protective net 8, maximizing the matching degree of the incident angle of sunlight and increasing the measured power generation efficiency by 15%. When a local photovoltaic panel 61 is damaged or broken, the flexible circuit board automatically switches through redundant lines to avoid failure of the entire photovoltaic network.
[0068] The embedded advantage is that the photovoltaic sheet 61 is conformally fitted with the protective net 8, reducing the shading area of the traditional bracket and saving 30% of space, while avoiding conflict with the warning light beam path.
[0069] The scratch-resistant film layer shows in the abrasion resistance test ASTMD1044 that the light transmittance of the film layer only decreases by 0.5% after 500 frictions, while the traditional glass decreases by 8%. Resistant to hail impact with a diameter of 25mm and a speed of 23m / s without damage, meeting the requirements of IEC61215 standard.
[0070] Through the synergistic effect of the anti-scratch film layer and the nano-hydrophobic coating 81 of the protective net 8, the speed at which water droplets and pollutants slide off is increased by 2 times, and the frequency of manual cleaning is reduced from once a month to once a quarter.
[0071] The 500F graphene supercapacitor supports low-temperature startup at -30°C and can maintain core functions for 72 hours after a power outage; the MPPT controller tracks the maximum power point of the photovoltaic panel in real time, with a conversion efficiency of >95%, a 10% increase over traditional PWM controllers.
[0072] In the power supply priority strategy, in normal mode, priority is given to powering the visibility sensor 71 and the control module 4. In emergency mode, non-core loads such as the projection lamp group 54 are cut off to ensure the operation of the laser lamp group 52 and the vibration sensor.
[0073] Since urban pile foundation construction often faces challenges such as uneven ground, potholes, or different hole sizes, traditional fixed support rods are difficult to adapt quickly. The first drive assembly 13 includes an electric telescopic guide rod 131, the bottom of which is fixed to the second drive assembly 14; The output end of the electric telescopic guide rod 131 is connected to the top of the first support rod 11 through a hinge, which can achieve ±5° angle adjustment; The limit switch is located within the electric telescopic guide rod 131. The control module 4 controls the telescopic speed and travel of the electric telescopic guide rod 131 via PWM signals. In foggy or rainy weather, the height of the warning assembly needs to be adjusted to optimize laser penetration or drainage efficiency. In strong winds, the center of gravity needs to be lowered to prevent tipping. The ±5° angle adjustment capability, coupled with a hinge connection, allows for fine-tuning of the top of the first support rod 11, ensuring the tops of the multiple support rods are aligned with a horizontal plane with an error of less than 1 cm, creating a stable mounting surface suitable for mounting the panel 3.
[0074] The second drive assembly 14 includes a servo motor 141, one end of which is fixed to the bottom of the electric telescopic guide rod 131 by welding. A handle 142 is provided on the outside of the servo motor 141, and the connecting member passes through the handle 142 to position and connect multiple servo motors 141; One end of the second support rod 12 is inserted into the output end of the servo motor 141, and the other end of the second support rod 12 is a threaded tip 121; The control module 4 adjusts the insertion depth into the ground through a closed-loop PID algorithm.
[0075] The connecting member includes a longitudinal steel bar 2, which is longitudinally distributed along the periphery of the conical support structure and is sleeved on the conical support structure; The diameter of the longitudinal steel bars 2 gradually decreases from bottom to top.
[0076] Precise PWM control adjusts the telescopic guide rod 131's extension speed from 0.1-0.5m / s and travel from 0-30cm via pulse-width modulation signals, enabling rapid deployment with a single-rod adjustment time of less than 5 seconds, adapting to sudden weather changes. Internal limit switches prevent mechanical jamming due to over-extension, extending equipment life, making it particularly suitable for municipal construction scenarios requiring frequent adjustments.
[0077] Due to the differences in ground conditions, the soil types at the construction site are diverse, such as sand, clay, and concrete, and the insertion depth needs to be dynamically adjusted to ensure the stability of the structure.
[0078] For example, if there are wind / impact resistance requirements, strong winds >15m / s or collision events such as accidental vehicle collisions, the connection between the support rod and the ground needs to be quickly reinforced.
[0079] The servo motor 141 adjusts the insertion depth of the second support rod 12 in real time according to the feedback from the vibration sensor with an accuracy of ±0.5cm. The insertion depth in sand reaches 40cm, and the pre-drilled hole of the threaded tip 121 in concrete achieves a stable fixation of 15cm.
[0080] The tapered thread design with a 5mm pitch increases the contact area with the soil, improving pullout resistance by 50% compared to a smooth rod. The structural overturning rate in strong winds is less than 0.1%. From detecting strong winds to completing the reinforcement insertion, it takes only 3 seconds, a 90% improvement in efficiency compared to traditional manual fixing.
[0081] Based on the severe weather scenario requirements of pile foundation opening protection equipment, the core parameters and load calculation of servo motor 141 power and waterproof performance are as follows: The servo motor needs to drive the second support rod 12 to be inserted into the ground. The soil types include sand, clay and concrete. The insertion depth is 40cm sand to 15cm concrete.
[0082] Load estimation: Sand resistance Assuming the soil resistance coefficient is 500 kPa and the insertion area thread tip 121 contact surface is 50 cm², the required thrust is 2500 N; Torque requirement: The thread diameter of the support rod is Φ20mm and the radius is 0.01m. Torque T = thrust × radius = 2500N × 0.01m = 25Nm; The speed requirement is that the insertion time must be less than 5 seconds to complete a 40cm stroke, so the speed is approximately 120rpm, which corresponds to a speed when the pitch is 5mm.
[0083] Power calculation: Formula: Power P = Torque T × Angular velocity ωω = 2πn / 60; Substitute the data: ω=2π×120 / 60≈12.57rad / s; P = 25 Nm × 12.57 rad / s ≈ 314 W; Redundancy Considering the mechanical efficiency gear transmission efficiency of 85%, impact load and long-term operation loss, a servo motor 141 with a power of 750W is selected.
[0084] In this embodiment, Panasonic MINASA6 series 750W can be selected, with a rated torque of 4.7Nm and an overload capacity of 200%; The reduction mechanism is matched with a 1:10 planetary reducer to output a torque of 47Nm, meeting the insertion requirements and reducing the motor load.
[0085] Severe weather scenarios: The equipment must operate in heavy rain with an intensity greater than 2 mm / h, temporary immersion in hazardous environments, and high humidity greater than 90%. The servo motor 141 housing must meet IP67 dustproof and water-proof protection or IP68, which is higher.
[0086] The cable inlet uses an EPDM rubber waterproof connector with a heat-shrinkable waterproof sleeve with a shrinkage ratio of 3:1; the interior of the motor is filled with inert gas nitrogen or potted with epoxy resin with insulation grade F to prevent moisture from invading the winding.
[0087] IP67 test: the motor is immersed in 1 meter of water for 30 minutes and then powered on and running, with no leakage and insulation resistance > 100MΩ; Salt spray test: the shell has no rust after 1000 hours of salt spray test ASTMB117, which meets the requirements of ISO9223C4 level corrosion environment.
[0088] The 750W 141 servo motor paired with a reducer delivers 47Nm of torque, capable of handling 2500N thrust in sand and soil, and the higher resistance of concrete, preventing equipment damage due to jamming. The IP67 protection rating ensures normal operation in heavy rain and hazardous environments. Salt spray testing verifies long-term corrosion resistance, extending the equipment lifespan to over five years. The device operates stably in winds up to level 12, heavy rain, and features IP67 waterproofing and anti-condensation coating in heavy fog, reducing accidental entry by over 90%.
[0089] Since the conical support structure needs to shrink in diameter from bottom to top to reduce wind resistance, traditional equal-diameter steel bars are prone to redundant strength at the top and insufficient load-bearing at the bottom.
[0090] The mechanical distribution is optimized by gradually changing the diameter. The bottom steel bar has a diameter of Φ12mm and a bending strength of >400MPa to support the main load. The top Φ8mm reduces the weight and the overall weight is reduced by 30%, which is adapted to the mechanical requirements of the tapered structure.
[0091] The sleeve is formed by welding the steel bar tails and is sleeved on the conical supporting structure.
[0092] The stainless steel material is combined with the nano-coated protective net 8, and the salt spray test is resistant to 1000 hours without rust, which is suitable for coastal or high-humidity construction environments.
[0093] Example 2 Reference Figure 1-5 As shown; This embodiment is basically the same as the embodiment 1, except that the solar photovoltaic power generation assembly 6 includes a photovoltaic solar panel 63 , and the photovoltaic solar panel 63 is fixedly connected to the support rod via a metal clip 82 .
[0094] This embodiment replaces the traditional embedded photovoltaic cell 61 design by directly fixing the photovoltaic solar panel 63 to the support rod via a metal clip 82. Its core advantages are: improved structural stability and ease of maintenance. The metal clip 82 provides quick assembly and disassembly capabilities, allowing the photovoltaic panel to be independently disassembled and assembled without affecting the overall structure of the protective net 8, facilitating targeted replacement in the event of local damage, reducing costs by 40%; at the same time, the rigid connection between the photovoltaic panel and the support rod enhances wind load resistance and can withstand wind speeds of level 12, avoiding fluctuations in power generation efficiency caused by deformation of the flexible circuit board; in addition, the independent photovoltaic panel can use a higher conversion efficiency monocrystalline silicon module with an efficiency of >22%, which is 10% higher than the embedded photovoltaic cell 61. At the same time, the optimal lighting inclination angle can be achieved by adjusting the clip angle, further ensuring the stability of the equipment's self-power supply in severe weather.
[0095] Example 3 Reference Figure 1-5 As shown; This embodiment is a further design of embodiment 1 or 2, wherein the environmental monitoring component 7 includes a visibility sensor 71, specifically a laser scattering sensor, which is installed on the top of the warning component and has a detection range of 0-10m; The vibration sensor is specifically an acceleration sensor 72, which is suspended and installed below the protective net 8 in the middle of the second support rod 12 to detect the vibration intensity threshold; the impact of people / vehicles is identified by the impact sensor, and the second support rod 12 is driven further into the ground by the second drive component 14 to strengthen the fastening force.
[0096] The proximity sensor is specifically a millimeter wave radar 73, which is installed on the first support pole 11 outside the conical support structure to detect moving objects within a meter and distinguish between people and vehicles.
[0097] The warning light group 5 includes a lamp tube 51, a laser light group 52 vertically arranged in the middle of the lamp tube 51, and a flash light group 53 arranged on the side of the lamp tube 51. The laser light group 52 and the flash light group 53 are electrically connected to the control module 4. The differentiated response mode is triggered according to the environmental data, and the warning mode of the laser light group 52 and the flash light group 53 is switched on. In a high-particle environment such as foggy or hazy days, an obvious laser column is formed above the equipment to improve the adaptability of the equipment in bad weather. The system also includes a projection lamp assembly 54 obliquely mounted on the outer side of the lamp tube 51 and a sound module 55 mounted inside the lamp tube 51. The projection lamp assembly 54 is electrically connected to the sound module 55. The proximity sensor detects the approach of a person or vehicle, turns on the projection lamp assembly 54 to project a hazard warning around the perimeter, and the sound module 55 cooperates to generate a secondary warning.
[0098] Because the penetration of traditional warning lights drops sharply to less than 50 meters in heavy fog and haze due to light scattering, accidents of accidental entry are frequent; By installing it on the top of the warning component, it monitors the visibility of 0-10m in real time and triggers a differentiated response mode: when the visibility is <50m, the laser light group 52 switches to a green light focusing mode with a divergence angle of 10° and a penetration of 200 meters. In foggy and hazy days, it automatically starts a high-frequency flash of 2Hz to break through the interference of particle occlusion through the flashing frequency.
[0099] By increasing the laser warning coverage radius to 200 meters, the pedestrian error rate has dropped by 92%, and the transmittance of the protective net 8 has been dynamically adjusted from 50% to 80%, enhancing internal light transmission to assist in warning. The laser wavelength of 520nm green light has a 30% higher penetration than the 630nm red light due to the high sensitivity of the human eye and strong atmospheric penetration.
[0100] Traditional equipment lacks a response mechanism for impact events, making it prone to overturning or structural failure due to vehicle or personnel collisions. Suspended and mounted in the middle of the second support rod 12, it detects a vibration intensity threshold greater than 5g and triggers an alarm. Upon confirmation of an impact, the servo motor 141 drives the second support rod 12 15cm deeper into the ground, enhancing its anti-overturning capability. Simultaneously, an audible and visual warning is activated, with the strobe light flashing at a high frequency and the sound module 55 playing a siren sound. Traditional infrared / ultrasonic sensors are susceptible to weather interference and cannot distinguish between pedestrians and vehicles, resulting in a single warning mode; By installing it outside the first support pole 11, it can detect moving objects within 10 meters and distinguish their types: When a pedestrian approaches <2m, the projection light assembly 54 projects a red warning strip with a width of 1m, and the sound module 55 plays a voice alarm; When the vehicle approaches <5m, the strobe light group 53 will flash at a high frequency of 2Hz and the voice alarm will sound "Construction ahead, please detour"; It supports operation at night and in severe weather conditions such as rain and snow, with a misjudgment rate of <1%. Differentiated warnings reduce ineffective interference, resulting in a pedestrian dispersal rate of 90% and a vehicle response rate of 85%. The radar operates at a frequency of 24GHz and a wavelength of 12.5mm, which can penetrate rain and fog and identify target speed Doppler effects and contour echo feature analysis, distinguishing between pedestrian speeds <1.5m / s and vehicle speeds >2m / s.
[0101] Since a single warning mode cannot cover complex weather conditions and crowd needs, a dynamic switching strategy is required; Laser light set 52: green light spot mode for heavy fog, red light strobe mode for strong wind; Strobe light group 53: high-frequency flashing for heavy rain, low-frequency flashing for daily use; Projection lamp group 54: projects dynamic warning pattern arrows and warning tapes with a coverage radius of 15 meters; Sound module 55: outputs directional voice alarm 120dB; Through multi-modal warnings: visual laser / strobe / projection combined with auditory voice dual dispersal, the accident rate of accidental entry is reduced by 90%; The projection lamp group 54 adopts a DLP micro-projection module with a resolution of SVGA and supports customized warning patterns such as escape routes.
[0102] Control module 4 uses an ARM Cortex-M7 processor and runs edge AI algorithms such as KNN classifiers to identify complex threats such as fog and collisions in real time.
[0103] Reference Figure 1-8 As shown; A method for using a conical safety protection device for a pile foundation opening, comprising the following steps: S1, by adjusting the support rod group 1 to form a conical protective cover, integrated power generation safety block assembly and environmental monitoring assembly 7, to establish basic protection and energy supply system; S2, collects data in real time through environmental sensors, maintains regular warning mode and dynamically optimizes equipment status; S3 triggers a differentiated response mode based on environmental data, switching on the warning mode of the laser light group 52 and the strobe light group 53. In high-particle environments such as fog or haze, a clear laser beam is formed above the device, improving the device's adaptability in adverse weather conditions; S4, through the proximity sensor to identify personnel / vehicles approaching, open the projection light group 54 to form a dangerous projection warning in the surrounding area, through the sound module 55 with the formation of a secondary warning; S5, the impact of a person or vehicle is recognized by the impact sensor, and the second driving assembly 14 drives the second support rod 12 further into the ground to strengthen the fastening force.
[0104] By dynamically deploying conical support structures to achieve physical isolation of the pile foundation opening, combined with solar power generation and environmental monitoring systems to sense external conditions in real time, and utilizing the intelligent control module 4 to link warning components and drive mechanisms, the system proactively adjusts the device configuration and warning mode in inclement weather, forming a three-dimensional protection system that covers visibility compensation, structural stability enhancement, and pedestrian / vehicle dispersal. Specifically, the system includes the following steps: In step S1, a conical protective cover is formed by adjusting the support rod group 1, integrating the power generation safety barrier component and the environmental monitoring component 7, and establishing a basic protection and energy supply system.
[0105] S11. Expand multiple support rods 1 around the pile opening, adjust the height of the first support rod 11 to a uniform level by the electric telescopic guide rod 131 of the first drive assembly 13, and use the servo motor 141 of the second drive assembly 14 to rotate the second support rod 12 inserted into the ground and fixed; support rod group 1 is provided with 4 groups; S12. The high-strength PE protective net 8 is covered on the surface of the conical support structure, connected to the support rod group 1 through the metal buckle 82, the embedded solar photovoltaic sheet 61 is connected in series through the flexible circuit board to form a photovoltaic network, the inverter and energy storage battery are integrated into the set plate 3; S13. Install the laser light group 52, strobe light group 53, projection light group 54 and sound module 55 of the warning component, and calibrate the visibility sensor 71, vibration sensor, acceleration sensor 72 and millimeter wave radar 73.
[0106] In step S2, data is collected in real time through environmental sensors to maintain a regular warning mode and dynamically optimize the device status.
[0107] S21. The control module 4 automatically performs a self-test procedure after power is turned on to detect the function of the drive components, the photovoltaic output voltage and the energy storage battery capacity; S22. During the day, the strobe light group 53 is activated to flash at a low frequency of 0.5 Hz. At night, the laser light group 52 is switched to cover the surrounding area. The light transmittance of the protective net 8 is maintained at 50% to balance the requirements of shielding and ventilation. S23. The visibility sensor 71 continuously monitors the atmospheric transparency, the millimeter-wave radar 73 scans the trajectory of moving objects within a range of 10 meters, and the vibration sensor records the ground impact signal. The data is uploaded to the control module 4 for analysis in real time.
[0108] In step 3, a differentiated response mode is triggered according to environmental data to dynamically adjust the laser warning penetration, the light transmittance of the protective net 8, and the wind resistance / drainage performance of the structure to improve the adaptability of the equipment in severe weather.
[0109] S31. Heavy Fog Mode: When visibility is less than 50m, the laser light assembly 52 switches to a green light spot mode of 5-20nm with a divergence angle of 10°. The projection light assembly 54 projects a green escape arrow. The sound module 55 activates infrasound to disperse the crowd. The light transmittance of the protective net 8 is increased to 80% to enhance internal light transmission. S32. Heavy Rain Mode: When low visibility <100m and high humidity >90% are detected, strobe light assembly 53 flashes at a high frequency of 2Hz and a voice alarm plays: "Danger ahead, please detour." The electrically retractable guide rod 131 shortens the height of the first support rod 11, tilting the protective net 8 30° to accelerate drainage. The energy storage system switches to supercapacitors for priority power supply. S33. Strong wind mode: When the wind speed is greater than 15 m / s, the servo motor 141 drives the second support rod 12 to penetrate deeper into the ground, the light transmittance of the protective net 8 is reduced to 10% to reduce wind resistance, and the laser light group 52 is turned off to prevent the beam from shaking and interfering with the driver's vision.
[0110] In step 4, vibration and proximity sensors are used to identify impact or power outage events, and backup power supply, structural reinforcement, and remote alarm mechanisms are activated to ensure continuous equipment operation and accident tracing. S41. Impact event response: When the vibration sensor detects an impact intensity > 5g, the sound module 55 plays a high-decibel siren, the servo motor 141 rotates the support rod to further stabilize the structure, and the millimeter-wave radar 73 locks the impact source and links the alarm through the municipal platform; S42. Power outage emergency: When the energy storage battery voltage is less than 10.5V, non-core loads such as the projection lamp group 54 are cut off, the hydrogen fuel cell backup power supply is started, and the laser lamp group 52 is switched to low power mode with a power of 20W to maintain basic warning functions.
[0111] In addition, sensors are calibrated regularly, photovoltaic panels are cleaned and drive mechanisms are lubricated. After a disaster, normal mode is automatically restored and event data is uploaded to the municipal platform to achieve full-cycle management.
[0112] Clean the surface stains of the photovoltaic panel 61 and check the fastening status of the metal buckle 82 every week; calibrate the sensor detection accuracy, lubricate the drive assembly gear set and test the performance of the hydraulic buffer every month; After the bad weather ends, the control module 4 automatically returns to normal mode, the light transmittance of the protective net 8 is adjusted back to 50%, the guide groove is closed, and the laser light group 52 enters the standby state; Record event data time, weather type, response action and upload to the municipal management platform to support remote monitoring and event tracing.
[0113] The dynamic adjustment of the transmittance and inclination of the protective net 8 through the telescopic and rotating linkage of the support rod group 1 achieves both physical isolation and environmental adaptability. Solar power generation prioritizes energy supply, while supercapacitors and hydrogen fuel cells are used in a multi-tiered manner to ensure core functionality, ensuring 72-hour uninterrupted operation in inclement weather. Laser penetration, infrared projection, and voice dispersal methods combine to address differentiated pedestrian and vehicle warning needs, reducing the risk of unauthorized entry by over 90%. Wireless communication uploads device status and event data, supporting remote monitoring and integration with city-level safety warning systems.
[0114] In a simulated foggy weather test, the laser warning had a penetration of 200 meters and the pedestrian error rate dropped by 92%. In heavy rain mode, the drainage efficiency increased by 40%, and the response time of the control module 4 was less than 1 second.
