Description

Technical Field

[0001] The utility model belongs to the technical field of safety warning devices, in particular to a civil engineering construction safety warning device. Background Art

[0002] Civil construction safety warning devices are used on construction sites to alert workers to safety and prevent accidents. Existing safety warning devices include audible and visual warnings, cordon lines, warning tape, and electronic display screens. Cordon lines and warning tapes are used to physically isolate dangerous areas on construction sites, providing clear markings to remind workers to stay away or exercise caution.

[0003] Existing cordon lines and warning tapes are typically marked with eye-catching colors and symbols to attract the attention of construction workers. During bright daylight hours, construction workers can clearly see these lines and tapes. However, at night, when light is dim, they are less visible. While some cordon lines and tapes are enhanced by reflective or fluorescent materials to enhance nighttime visibility, reflective materials rely on external light sources to reflect light, while fluorescent materials absorb light energy during the day and emit light at night, stopping their glow after releasing the absorbed light energy. Therefore, existing cordon lines and tapes do not naturally emit light to provide warnings at night, and their warning effectiveness is suboptimal. Utility Model Content

[0004] The purpose of the utility model is to provide a civil engineering construction safety warning device to solve the problem in the above background technology that the existing warning line and warning tape type warning devices cannot emit light naturally at night.

[0005] The utility model is achieved through the following technical solutions:

[0006] A civil engineering construction safety warning device includes a control box, a single-chip microcomputer, a warning tape, a photoresistor, a human infrared sensor, and a power supply module. The single-chip microcomputer is installed inside the control box, and a column is fixed to the top surface of the control box.

[0007] One end of the warning tape is fixed to the column, and the other end is provided with a traction column for tensioning the warning tape. An LED light strip extending along its length is fixed to the front surface of the warning tape;

[0008] The photoresistor and the human infrared sensor are both fixedly mounted on the top outer side wall of the column;

[0009] The power supply module, photoresistor, human infrared sensor and LED light strip are all electrically connected to the single chip microcomputer. The power supply module is used to supply power, the photoresistor is used as a light-controlled switch of the LED light strip circuit, the human infrared sensor is used to detect pedestrians, and the single chip microcomputer is used to control the LED light strip to light up or go out.

[0010] At a civil construction site, the warning tape of the alarm device is used to isolate dangerous areas. The control box and the column can be fixed to the ground, and the warning tape must be tightened to isolate the dangerous area. During the day, due to sufficient ambient light, the photoresistor is used as a light-controlled switch and is in a normally open state. Regardless of whether the human infrared sensor detects pedestrians, the LED light strip is always off during the day. At night, when the ambient light is dim, the photoresistor is used as a light-controlled switch and is in a normally closed state. The human infrared sensor can detect whether there are pedestrians entering its detection range. When it detects pedestrians, it can send a signal to the microcontroller to control the LED light strip to light up. After the pedestrian leaves its detection range, the LED light strip goes out. The alarm device can naturally emit light at night to warn pedestrians, thereby enhancing the night warning effect.

[0011] Further definition, the front surface of the warning tape is sprayed with a warning coating, which extends in a strip shape and is located on the upper and / or lower side of the LED light strip. The warning coating can make the warning tape more eye-catching and help remind construction workers to stay away from or be careful of dangerous areas; the warning coating is a fluorescent material coating or a reflective material coating.

[0012] Further definition, the warning coating is provided with two, respectively located on the upper side and the lower side of the LED light strip, one of the warning coatings is a fluorescent material coating, and the other warning coating is a reflective material coating. The fluorescent material coating can absorb light energy and emit light to warn at night, which can enhance the night warning effect of the warning strip. The reflective material coating can reflect light to improve visibility, which can enhance the daytime warning effect of the warning strip and the warning effect when a light source illuminates the warning strip at night.

[0013] Further definition, the power supply module includes a battery and a photovoltaic cell. The battery is installed in the control box and is electrically connected to the single-chip microcomputer. The photovoltaic cell is installed at the top of the column and is electrically connected to the single-chip microcomputer and the battery. The power supply module is a solar power supply module, which can help save energy. The alarm uses solar power supply and is not easily affected by the limitation of not being able to draw city electricity at the site of use.

[0014] As a further limitation, the column is a hollow tubular structure, which can facilitate the layout of circuit lines therein.

[0015] Further limitations are that a voice announcer is installed on the top outer wall of the column, and the voice announcer is electrically connected to the single-chip microcomputer. When the human infrared sensor detects a pedestrian, the single-chip microcomputer can control the voice announcer to issue targeted audible safety warnings, such as broadcasting "Danger area, do not approach..." to remind pedestrians to pay attention to safety.

[0016] Further definition, the top of the traction column is fixedly installed with a top plate, one end of the top plate is fixed with a U-shaped disc rack, and the U-shaped disc rack is installed with a reel for reeling in and out the warning tape. The reel can rotate relative to the U-shaped disc rack, and the warning tape can be reeled in or out using the reel.

[0017] Further definition, the side wall of the U-shaped disc rack is threadedly connected with a locking screw for locking the reel. When the locking screw is tightened, the end of the locking screw can be used to press against the reel to prevent the reel from rotating. When reeling and unreeling the warning tape, the reel can be rotated after loosening the locking screw.

[0018] Further definition, the other end of the top plate is provided with a hanging hole, and the outer wall of the column is installed with an L-shaped hook that can be inserted into the hanging hole for hooking the top plate. After the alarm is used, the warning tape is rolled up using a reel, and then the top plate can be hooked on the L-shaped hook for easy gathering and management.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The warning device can use warning tape to isolate dangerous areas at civil construction sites, and can use columns and traction columns to tension the warning tape. During the day, due to sufficient ambient light, the photoresistor is used as a light-controlled switch and is in a normally open state during the day. Regardless of whether the human infrared sensor detects pedestrians, the LED light strip is always in a continuously off state during the day. At night, the ambient light is dim, and the photoresistor is used as a light-controlled switch and is in a normally closed state at night. The human infrared sensor can detect whether there are pedestrians entering its detection range. When it detects pedestrians, it can send a signal to the microcontroller to control the LED light strip to light up. After the pedestrian leaves its detection range, it can control the LED light strip to turn off. The warning device can use the human infrared sensor to sense pedestrians at night, and can control the LED light strip to emit light to warn pedestrians, which can enhance the night warning effect.

[0029] A civil engineering construction safety warning device, such as Figure 1 As shown, it mainly consists of a control box 1, a single-chip microcomputer 2, a column 4, a warning tape 10, a traction column 16, a reel 13, an LED light strip 11, a photoresistor 6, a human infrared sensor 9, a voice announcer 8 and a power supply module; the power supply module is a solar power supply module, which includes a battery 3 and a photovoltaic cell 7;

[0030] like Figure 1 As shown, the single chip computer 2 and the battery 3 are both installed inside the control box 1, the bottom end of the column 4 is welded to the top surface of the control box 1, and the photovoltaic cell 7 is fixedly installed on the top of the column 4;

[0031] like Figure 1 and Figure 2As shown, a top plate 15 is fixedly mounted on the top of the traction column 16, a U-shaped disc frame 14 is fixed to one end of the top plate 15, a reel 13 is mounted on the U-shaped disc frame 14, and the reel 13 can rotate in the U-shaped disc frame 14. A connecting plate is welded to the middle side wall of the column 4, one end of the warning tape 10 is fixed to the connecting plate, and the other end is wound around the reel 13. The reel 13 can be used to reel or unreel the warning tape 10. After unreeling the warning tape 10, the traction column 16 can be fixed to the ground to tension the warning tape 10.

[0032] like Figure 1 As shown, the front surface of the warning tape 10 is fixed with an LED light strip 11 extending along its length direction;

[0033] like Figure 1 As shown, the photoresistor 6, the human infrared sensor 9 and the voice announcer 8 are all fixedly mounted on the top outer wall of the column 4;

The photovoltaic cell 7 can convert solar energy into electrical energy and store it in the battery 3. The battery 3 can power the entire system. The photoresistor 6 is used as a light-controlled switch for the LED light strip 11 circuit. The human infrared sensor 9 is used to detect pedestrians. The single-chip microcomputer 2 is used to control the LED light strip 11 to light up or go out and to control the voice announcer 8 to sound or stop sounding. When the human infrared sensor 9 detects a pedestrian, the single-chip microcomputer 2 can control the voice announcer 8 to issue a targeted audible safety warning, such as broadcasting "dangerous area, do not approach..." to remind pedestrians to pay attention to safety;

[0035] The power supply module is a solar power supply module, which is beneficial to saving energy. The alarm is powered by solar energy and is not easily restricted by the inability to draw mains electricity at the site of use.

[0036] In this embodiment, Figure 1 As shown, the column 4 is a hollow tubular structure, which can facilitate the layout of circuit lines therein;

[0037] The traction column 16 is also a hollow tubular structure, which can reduce its weight.

[0038] In this embodiment, the control box 1 is made of aluminum alloy or stainless steel plates welded together, and a maintenance door is provided on one side wall;

[0039] The upright column 4 and the traction column 16 are pipes made of aluminum alloy or stainless steel;

[0040] like Figure 1As shown, the bottom end of the control box 1 is welded with a flange, and a socket is provided on the flange to facilitate anchoring it to the ground using anchor nails, thereby ensuring the stability of the column 4;

[0041] like Figure 1 As shown, a bottom plate 17 is welded to the bottom end of the traction column 16 , and a socket is provided on the bottom plate 17 so that it can be anchored to the ground with anchor nails, thereby ensuring the stability of the traction column 16 .

[0042] In this embodiment, Figure 1 and Figure 2 As shown, the side wall of the U-shaped reel frame 14 is threadedly connected to a locking screw 18 for locking the reel 13. When the locking screw 18 is tightened, the end of the locking screw 18 can be used to press against the reel 13 to prevent the reel 13 from rotating. When the warning tape 10 is wound up or unwound, the reel 13 can be rotated after loosening the locking screw 18.

[0043] like Figure 1 、 Figure 2 and Figure 4 As shown, a hanging hole 19 is provided at the other end of the top plate 15, and an L-shaped hook 5 is installed on the outer wall of the column 4, which can be inserted into the hanging hole 19 for hooking the top plate 15. After the alarm is used, the warning tape 10 is rolled up by the reel 13, and then the top plate 15 can be hooked on the L-shaped hook 5 for easy gathering and management.

[0044] In this embodiment, Figure 1 and Figure 2 As shown, the front surface of the warning tape 10 is sprayed with a warning coating 12, which extends in a strip shape. There are two warning coatings 12, which are respectively located on the upper and lower sides of the LED light strip 11. One warning coating 12 is a fluorescent material coating, and the other warning coating 12 is a reflective material coating. The fluorescent material coating can absorb light energy and emit light for warning at night, which can enhance the night warning effect of the warning tape 10. The reflective material coating can reflect light to improve visibility, which can enhance the daytime warning effect of the warning tape 10 and the warning effect when a light source illuminates the warning tape 10 at night. The warning coating 12 can make the warning tape 10 more eye-catching, which helps to remind construction workers to stay away from or be careful of dangerous areas.

[0045] In this embodiment, the warning tape 10 is made of soft plastic (such as PVC, PE, etc.) or a fabric tape such as nylon or polyester. The LED light strip 11 is an existing product that can be purchased online or offline. It is embedded in the surface of the warning tape 10 and fixed with glue. Both the warning tape 10 and the LED light strip 11 are flexible and can be bent, which can facilitate the reel 13 to reel in and out.

[0046] The system composed of the above-mentioned single-chip microcomputer 2, solar power supply module, photoresistor 6 and human infrared sensor 9 is an existing technology, which is often used in solar street lights. It can be modified with reference to the existing solar street lights, and the street light liabilities of the solar street lights can be replaced with LED light strips 11. Among them, the single-chip microcomputer can adopt the HT46R23 model, the photoresistor 6 can adopt the XH-M131 model, the human infrared sensor 9 can adopt the AMG88 series, and the voice announcer 8 can adopt the TY-7 model.

[0047] The working principle of this utility model:

[0048] At a civil construction site, the warning tape 10 of the warning device is used to isolate a dangerous area. The flange at the bottom of the control box 1 is anchored to the ground with anchor nails. The traction column 16 is moved and the warning tape 10 is unwound. After the warning tape 10 is tightened, the bottom plate 17 at the bottom of the traction column 16 is anchored to the ground with anchor nails. The pulled warning tape 10 isolates the dangerous area.

[0049] During the day, when the ambient light is sufficient, the photovoltaic cell 7 converts solar energy into electrical energy and stores it in the battery 3 to provide the power required by the entire warning system. The photoresistor 6 is used as a light-controlled switch and is in a normally open state during the day. Regardless of whether the human infrared sensor 9 detects a pedestrian, the LED light strip 11 is always in a continuously extinguished state during the day. When the human infrared sensor 9 detects a pedestrian entering its detection range, the single-chip microcomputer 2 controls the voice announcer 8 to issue a targeted audible safety warning, such as "Danger area, do not approach..." to remind pedestrians to pay attention to safety. After the pedestrian leaves the detection range, the voice announcer 8 stops sounding;

[0050] At night, the ambient light is dim, the photoresistor 6 is used as a light-controlled switch and is in a normally closed state. The human infrared sensor 9 can detect whether a pedestrian enters its detection range. When a pedestrian is detected, it sends a signal to the single-chip microcomputer 2 to control the single-chip microcomputer 2 to light up the LED light strip 11. At the same time, the single-chip microcomputer 2 controls the voice announcer 8 to issue a targeted voice safety warning to remind pedestrians to pay attention to safety. When the pedestrian leaves the detection range of the human infrared sensor 9, the LED light strip 11 goes out and the voice announcer 8 stops sounding. Therefore, the condition for the LED light strip 11 to light up is that the ambient light is dim at night and the pedestrian enters the detection range of the human infrared sensor 9. When no pedestrian is detected, the LED light strip 11 does not need to light up, which can help save energy.

[0051] The warning device can use the human infrared sensor 9 to sense pedestrians at night, can control the LED light strip 11 to emit light, and the voice announcer 8 to sound to warn pedestrians, and can enhance the night warning effect.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
