Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to an intelligent safety protection device for construction sites. Background Technology

[0002] Construction site protection is a crucial measure to ensure the smooth progress of the project, protect personnel safety, and maintain the surrounding environment. Regarding personnel safety, various safety warning signs will be set up at the construction site, and sturdy guardrails and safety nets will be erected to prevent falls and being struck by objects. Workers must also be equipped with qualified safety helmets, safety belts, and other personal protective equipment. From an environmental perspective, dust control measures will be implemented, such as regular watering and covering or sealing materials that easily generate dust to reduce air pollution. Construction wastewater will be properly treated to prevent direct discharge into polluted water bodies without treatment.

[0003] Common safety protection measures include: safety nets: suspended around the perimeter of buildings to prevent falling objects from injuring people; guardrails: fixed to the edges of construction areas to prevent people from falling; and video surveillance systems: used to monitor the construction site in real time.

[0004] However, existing safety protection measures such as safety nets and guardrails can no longer meet the efficiency and safety requirements of modern construction. In recent years, the application of intelligent technology in the construction field has gradually increased, but intelligent safety protection devices for construction sites are still in the exploratory stage. Existing technologies mainly focus on passive protection and lack active early warning and real-time monitoring functions, resulting in limited accident prevention effects. Therefore, in order to address the above shortcomings, an intelligent safety protection device for construction sites is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent safety protection device for construction sites, aiming to improve the problem that some existing safety protection devices can only provide passive protection, cannot actively warn of potential dangers, and lack real-time monitoring functions, thus failing to detect safety hazards in a timely manner.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent safety protection device for construction sites, comprising a frame, a sensing alarm mechanism at the top of the frame, and a detachable panel mechanism at the front of the frame; the sensing alarm mechanism includes an infrared sensor, the bottom of which is installed at the top of the frame, a pressure sensor at the bottom of the frame, an angle sensor on the outer right side of the frame, a wireless signal transmitter on the top rear side of the frame, an audible and visual alarm on the top left side of the frame, an inspection component inside the frame, and a controller on the inner rear side of the frame.

[0007] The above technical solution involves using different sensors to monitor the construction site conditions. For example, infrared sensors detect the approach of people or objects, pressure sensors detect changes in bottom pressure, and tilt sensors monitor the tilt of the frame. Once a danger occurs, the controller receives the signal, activates the audible and visual alarm, and transmits the danger information to the monitoring center via a wireless signal transmitter, thus achieving intelligent safety protection.

[0008] As a further description of the above technical solution:

[0009] The inspection component includes a drone, the bottom of which is fixedly connected to the front of the inside of the frame, and a receiving platform is installed inside the drone.

[0010] Through the above technical solution, drones, with their high-definition cameras, long endurance, and autonomous flight planning capabilities, regularly inspect construction sites. During flight, they use high-definition cameras to capture images in real time, and transmit the image data back to the receiving platform, effectively expanding the monitoring range of safety protection devices and improving the comprehensiveness of safety monitoring at construction sites.

[0011] As a further description of the above technical solution:

[0012] The detachable panel mechanism includes a fixed shaft and two pull plates. The fixed shaft is externally fixedly connected to the front interior of the frame. A protective panel is rotatably connected to the outside of the fixed shaft. Two locking plates are fixedly connected to the rear of the protective panel. Each of the two locking plates has two locking slots inside. Two locking posts are slidably connected to the left and right sides of the inside of the frame. Springs are sleeved on the outside of the multiple locking posts. The adjacent sides of the two pull plates are fixedly connected to the distant sides of the multiple locking posts. Two sliding grooves are opened on the front side of the frame.

[0013] The above technical solution allows for the following: When disassembling the protective panel, pulling the pull plate causes the locking pin to move outward against the spring force, disengaging it from the slot and releasing the protective panel from the frame. At this time, the spring is compressed and stored energy is released. The pull plate is then released, and the spring releases its elastic potential energy, pushing the locking pin back into the slot. This enables the rapid installation and disassembly of the protective panel, facilitating the maintenance and adjustment of the protective device.

[0014] As a further description of the above technical solution:

[0015] Two mounting frames are fixedly connected to the rear side of the frame, and multiple heat dissipation holes are provided on both the left and right sides of the interior of the frame.

[0016] Through the above technical solution, the heat dissipation holes can effectively dissipate the heat generated by the electrical equipment inside the frame during the operation of the device, ensuring that the electrical equipment operates normally at a suitable temperature and maintaining the stable working state of the entire safety protection device.

[0017] As a further description of the above technical solution:

[0018] The controller is electrically connected to the infrared sensor, and the controller is electrically connected to the pressure sensor.

[0019] Through the above technical solution: When the infrared sensor is working, when a person or object enters the monitoring range, based on the principle of infrared reflection, the reflected signal changes and is converted into an electrical signal and transmitted to the controller; the pressure sensor is based on the piezoelectric effect. When the bottom of the frame is impacted by an object falling or when the pressure changes due to external force, the internal piezoelectric material generates an electrical signal change and transmits it to the controller, enabling the controller to obtain relevant data in a timely manner and provide a basis for subsequent hazard judgment.

[0020] As a further description of the above technical solution:

[0021] The card plate is externally slidably connected to the inside of the groove, and the card post is externally slidably connected to the inside of the groove.

[0022] The above technical solution allows the following: When disassembling or installing the protective panel, the clamping plate can move smoothly in the slide groove as the protective panel rotates, and the clamping post slides in the groove. When the pull plate is pulled to move the clamping post outward and disengage it from the groove, the protective panel can be disassembled. When the pull plate is released, the clamping post slides into the groove to complete the installation. The precise sliding cooperation ensures that the detachable panel mechanism works normally.

[0023] As a further description of the above technical solution:

[0024] One end of the spring is fixedly connected to the outside of the frame, and the other end of the spring is fixedly connected to the outside of the pull plate.

[0025] Through the above technical solution: when operating the detachable panel mechanism, pulling the pull plate causes the locking pin to move outward, and the spring is compressed to store elastic potential energy, providing energy for subsequent automatic reset; after releasing the pull plate, the spring releases elastic potential energy, pushing the pull plate and the locking pin connected to it to reset, so that the locking pin re-engages into the slot, realizing the rapid fixation of the protective panel. The spring plays a key role in energy storage and assisting reset.

[0026] As a further description of the above technical solution:

[0027] The frame is fixed to the edge of the construction area by bolts, and the controller is electrically connected to the tilt sensor, the wireless signal transmitter and the audible and visual alarm.

[0028] The above technical solution involves fixing the frame to the edge of the construction area with bolts to ensure the stability of the entire safety protection device. The controller is electrically connected to the tilt sensor, wireless signal transmitter, and audible and visual alarm. The tilt sensor monitors the changes in the tilt angle of the frame in real time and transmits the data to the controller.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the infrared sensor utilizes the principle of infrared reflection to convert changes in infrared signals caused by personnel or objects entering the monitoring range into electrical signals, which are then transmitted to the controller within a detection distance of 0.1-4m. The pressure sensor, based on the piezoelectric effect, transmits electrical signals generated by the internal piezoelectric material to the controller when pressure changes due to external force at the bottom of the frame. The tilt sensor monitors changes in the tilt angle of the frame in real time through the principle of gravity sensing and transmits signals to the controller. The controller receives data from each sensor in real time and analyzes and processes it according to preset danger judgment standards. Once a danger is detected, an audible and visual alarm consisting of a high-brightness LED light and a high-decibel speaker on the top left is immediately triggered. At the same time, an alarm command is sent to a wireless signal transmitter on the top rear side that is compatible with the communication system of the construction site monitoring center, has strong signal transmission capabilities, and is resistant to interference, thereby realizing proactive early warning and real-time monitoring.

[0031] 2. In this utility model, pulling the pull plate causes the locking pin to move outward against the spring force, allowing it to slide out of the slot, releasing the fixed connection and enabling quick disassembly. Two sliding grooves on the front side of the frame ensure stable movement and accurate alignment of the locking plate during the disassembly and installation of the protective panel, facilitating maintenance.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an intelligent safety protection device for construction sites, comprising a frame 1. The frame 1 serves as the basic support structure for the entire safety protection device, possessing good stability and load-bearing capacity. The frame 1 is fixed to the edge of the construction area by bolts. A sensing alarm mechanism 2 is installed on the top of the frame 1, and a detachable panel mechanism 3 is installed on the front side of the frame 1. The sensing alarm mechanism 2 includes an infrared sensor 21, model E3Z-T61, with a detection distance of 0.1-4m. The infrared sensor 21 operates based on the principle of infrared reflection. When a person or object enters its monitoring range, the reflected infrared signal changes. The sensor converts this change into an electrical signal and transmits the data to a controller 27 via an internal data line. The bottom of the infrared sensor 21 is installed on the top of the frame 1, and a pressure sensor 22 is installed on the bottom of the frame 1. The controller 27 and the pressure sensor 22 are electrically connected. The working principle of the pressure sensor 22 is based on the piezoelectric effect. When the bottom of the frame 1 is impacted by a falling object or other external forces, causing a change in pressure, the piezoelectric material inside the pressure sensor 22 will generate a corresponding change in electrical signal. This signal is transmitted to the controller 27 through a data line so that the controller 27 can analyze and determine whether there is a dangerous situation. An inclination sensor 23 is installed on the outer right side of the frame 1. The inclination sensor 23 can monitor the change in the tilt angle of the frame 1 relative to the vertical direction in real time. A wireless signal transmitter 24 is installed on the top rear side of the frame 1. The model of the wireless signal transmitter 24 is selected to be compatible with the communication system of the construction site monitoring center. It has strong signal transmission capability and anti-interference performance. Its main function is to send the alarm signal to the monitoring center in the form of a wireless radio frequency signal after the controller 27 detects a dangerous situation.

[0040] A sound and light alarm 25 is installed on the top left side of frame 1. The alarm 25 is a combination of a high-brightness LED light and a high-decibel speaker, capable of emitting a strong flash and a loud alarm sound simultaneously when triggered by the controller 27, to attract the attention of personnel at the construction site. An inspection component 26 is installed inside frame 1, including a drone 261. The bottom of the drone 261 is fixedly connected to the front side of the inside of frame 1. The drone 261 is equipped with a high-definition camera, long battery life, and autonomous flight planning capabilities. Its main task is to periodically inspect the construction site, expanding the monitoring range of the safety protection devices. The high-definition camera inside the drone 261 can capture real-time images of the construction site and transmit the image data back to the receiving platform 262. The receiving platform 262 is installed inside the drone 261. A controller is installed on the rear side of the inside of frame 1. The controller 27 uses an STM32F103 microcontroller and supports multi-sensor data fusion. The controller 27 is electrically connected to the infrared sensor 21, and also electrically connected to the tilt sensor 23, the wireless signal transmitter 24, and the audible and visual alarm 25. The controller 27 is connected to the infrared sensor 21, pressure sensor 22, tilt sensor 23, wireless signal transmitter 24, audible and visual alarm 25, and the receiving platform 262 in the inspection component 26 via data cables. It receives data from each sensor in real time, analyzes and processes this data, and, based on preset danger judgment criteria, immediately triggers the audible and visual alarm 25 to sound an alarm once a dangerous situation is detected, such as personnel approaching a dangerous area, objects falling, or the protective structure tilting. At the same time, it sends an alarm command to the wireless signal transmitter 24 and sends the danger information to the monitoring center.

[0041] Specifically, in the sensing and alarm mechanism 2, the infrared sensor 21 utilizes the principle of infrared reflection. When a person or object enters the monitoring range, the reflected infrared signal changes and is converted into an electrical signal, which is then transmitted to the controller 27. The pressure sensor 22 is based on the piezoelectric effect. When the bottom of the frame 1 is subjected to impact or external force causing a change in pressure, the internal piezoelectric material generates an electrical signal change, which is transmitted to the controller 27. The tilt sensor 23 monitors the change in the tilt angle of the frame 1 in real time. The wireless signal transmitter 24 sends an alarm signal to the monitoring center when the controller 27 detects danger. The audible and visual alarm 25 sounds when the controller 27 triggers the alarm. The system emits flashing lights and alarm sounds. The internal inspection component 26 of frame 1 includes a drone 261 equipped with a high-definition camera, which can periodically inspect the construction site and transmit image data back to the receiving platform 262. The controller 27 uses an STM32F103 microcontroller and is electrically connected to various sensors, wireless signal transmitter 24, audible and visual alarm 25, and receiving platform 262. It receives and analyzes data in real time. When a dangerous situation is detected, such as personnel approaching, objects falling, or the protective structure tilting, the audible and visual alarm 25 is triggered and an alarm message is sent to the monitoring center, thereby realizing safety protection and monitoring of the construction site.

[0042] Reference Figures 1 to 3 The detachable panel mechanism 3 includes a fixed shaft 31 and two pull plates 37. The fixed shaft 31 is externally fixedly connected to the front interior of the frame 1, and a protective panel 32 is rotatably connected to the outside of the fixed shaft 31. The size of the protective panel 32 is adapted to the size of the opening on the front interior of the frame 1, and can completely cover the space on the front interior of the frame 1 to provide protection. Two locking plates 33 are fixedly connected to the rear of the protective panel 32. The locking plates 33 can slide smoothly in the slide groove 38, which facilitates the movement of the locking plates 33 in the slide groove 38 as the protective panel 32 rotates when it is removed. Each of the two locking plates 33 has two slots 34 inside. Two locking posts 35 are slidably connected to the left and right sides of the interior of the frame 1. The outside of the locking posts 35 is slidably connected to the inside of the slots 34. Springs 36 are sleeved on the outside of the locking posts 35. When it is necessary to remove the protective panel 32, the pull plate 37 is pulled, and the pull plate 37 drives the locking posts 35 to overcome the springs 36. The elastic force displaces outward, causing the locking post 35 to slide out of the slot 34, thereby releasing the fixed connection between the protective panel 32 and the frame 1. One end of the spring 36 is fixedly connected to the outside of the frame 1, and the other end of the spring 36 is fixedly connected to the outside of the pull plate 37. The adjacent sides of the two pull plates 37 are respectively fixedly connected to the distant sides of the multiple locking posts 35. When the pull plate 37 is pulled to displace the locking post 35 outward, the spring 36 is compressed and stores elastic potential energy. When the pull plate 37 is released, the spring 36 releases elastic potential energy and pushes the locking post 35 to re-lock into the slot 34, realizing the rapid fixation of the protective panel 32. Two sliding grooves 38 are opened on the front side of the frame 1, and the outside of the locking plate 33 is slidably connected to the inside of the sliding groove 38. Two mounting frames 4 are fixedly connected to the rear side of the frame 1. Multiple heat dissipation holes 5 are opened on both the left and right sides of the inside of the frame 1. The heat dissipation holes 5 ensure that the heat generated inside the frame 1 can be effectively dissipated to ensure the normal operation of the electrical equipment.

[0043] Specifically, when disassembling the protective panel 32, pull the pull plate 37. The pull plate 37 drives the locking post 35 to move outward against the elastic force of the spring 36, causing the locking post 35 to slide out of the slot 34, thus releasing the fixed connection between the protective panel 32 and the frame 1. At this time, the spring 36 is compressed and stores elastic potential energy. After releasing the pull plate 37, the spring 36 releases elastic potential energy and pushes the locking post 35 to re-lock into the slot 34, thereby achieving quick fixation of the protective panel 32. Two mounting frames 4 are fixed on the rear side of the frame 1, and multiple heat dissipation holes 5 are opened on the left and right sides inside to dissipate the heat inside the frame 1 and ensure the normal operation of the electrical equipment.

[0044] Working Principle: When the intelligent safety protection device at the construction site is in operation, frame 1 is fixed to the edge of the construction area with bolts, providing support and fixation. The infrared sensor 21, pressure sensor 22, and tilt sensor 23 in the sensing and alarm mechanism 2 are respectively installed at the top, bottom, and outer right side of frame 1, monitoring the construction area in real time. Abnormal situations such as personnel approaching, objects falling, or the protective structure tilting are detected, and the data is transmitted to controller 27. Controller 27 analyzes and processes the data; once a danger is detected, it triggers the audible and visual alarm 25 to sound an alarm, and simultaneously sends an alarm to the monitoring center via wireless signal transmitter 24. The drone in the inspection component 26... 261 can conduct regular inspections of the construction site. Its internal receiving platform 262 can receive relevant information and link with the ground protection device to expand the monitoring range. The protective panel 32 is rotatably connected to the front side of the frame 1 through the fixed shaft 31. When the protective panel 32 needs to be disassembled, the pull plate 37 is pulled, and the pull plate 37 drives the locking post 35 to move, so that the locking post 35 slides out of the locking groove 34 of the locking plate 33. The locking plate 33 can slide in the sliding groove 38, thereby realizing the easy disassembly of the protective panel 32 and facilitating the installation, maintenance and other operations of the protective device. The entire device achieves active early warning and real-time monitoring through the coordinated work of multiple structures, adapts to the dynamic construction environment, and improves the safety of the construction site.
