Description

Technical Field

[0001] This utility model relates to the technical field of construction safety warning devices, and in particular to a construction safety early warning alarm device. Background Technology

[0002] In the construction of various projects such as water transport, water conservancy, and municipal engineering, the working environment is complex and ever-changing. There are often potentially dangerous places such as waterside areas, high-altitude edges, openings, hoisting operation areas, and near high-voltage power lines. These areas are prone to safety accidents due to human negligence, environmental factors, or management oversights. Traditional warning signs (such as signs and fences) rely on passive reminders and have limited effectiveness. Therefore, devices that can actively issue early warning and alarm signals have emerged. These devices monitor specific dangerous areas and can promptly issue voice or sound and light alarms when they detect personnel approaching, actively reminding on-site personnel to pay attention to the dangerous environment and avoid risky behaviors. This effectively makes up for the lack of human vigilance and is of great significance for improving the overall safety protection level of construction sites.

[0003] However, existing safety warning and alarm devices of this type still have significant shortcomings in practical applications. The viewing angle and coverage of their built-in detectors (such as infrared sensors) are usually relatively fixed, and it is difficult to flexibly adjust them according to actual needs after installation. For example, it is not easy to change the detection height to adapt to different work surfaces or differences in personnel height, nor is it easy to adjust the horizontal detection angle to accurately align with irregular boundaries (such as winding waterfronts or irregularly shaped opening edges) or avoid obstacles on site. This limitation in viewing angle adjustment leads to an increase in detection blind spots or false alarm risks, reducing the accuracy and reliability of warnings. These factors together restrict the effective application of existing safety warning devices in variable construction environments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a construction safety early warning alarm device, which solves the problem that the viewing angle and coverage of existing detectors are usually relatively fixed, and it is difficult to flexibly adjust them according to actual site needs after installation.

[0005] According to an embodiment of the present invention, a construction safety early warning alarm device includes an adjusting rod, the adjusting rod including a supporting outer rod and a sliding inner rod slidably sleeved in the supporting outer rod, the supporting outer rod is provided with a locking mechanism that can fix the sliding inner rod, a stable bracket is fixedly provided at the bottom of the supporting outer rod, and a power supply is fixedly provided at the top of the sliding inner rod;

[0006] The warning mechanism includes a rotating ring and a sensor. The rotating ring is coaxially rotatably mounted on the sliding inner rod. The sensor is rotatably connected to the rotating ring via a universal joint. A buzzer connected to the sensor is fixedly mounted on one side of the sensor. The sensor and the buzzer are electrically connected to the power supply.

[0007] The technical principle of this utility model is as follows: When in use, place the device near the dangerous area, adjust the relative position of the sliding inner rod and the supporting outer rod according to the actual situation of the area, and fix them by locking mechanism. That is, adapt to the construction environment by changing the height of the adjusting rod, and then rotate the rotating ring and adjust the angle of the universal joint so that the sensor can rotate at multiple angles to set the optimal monitoring range for the area that needs to be warned. When personnel are detected approaching, the alarm buzzer will sound to warn.

[0008] Furthermore, the locking mechanism includes several limiting holes fixedly disposed on the outer support rod and a top rod that is telescopically disposed on the inner sliding rod by a spring, the top rod extending out when it coincides with the limiting holes.

[0009] Furthermore, the outer support rod is provided with a sliding groove in the inner axial direction, and the inner sliding rod is fixedly provided with a guide strip on its side wall. The guide strip can be embedded in the sliding groove and slide relative to it.

[0010] Furthermore, the locking mechanism includes a tightening bolt, which is threaded onto the outer support rod and can be screwed into and abut against the inner sliding rod.

[0011] Furthermore, a first knob is threadedly connected to one side of the rotating ring. The first knob can be screwed into and pressed against the sliding inner rod. One end of the universal joint is fixedly connected to the rotating ring, and the other end is rotatably provided with a damping turntable. The sensor is fixedly installed on the damping turntable, and the buzzer is fixedly installed at the bottom of the damping turntable.

[0012] Furthermore, the sensor includes an infrared sensor, the bottom of which is fixedly connected to the damping turntable.

[0015] Furthermore, the stabilizing bracket includes several supporting legs, with more than three supporting legs. The supporting legs are hinged around the bottom of the outer supporting rod. A stabilizing foot is rotatably provided at the bottom of the supporting leg. A fifth knob that can be screwed to a side of the stabilizing foot is threaded to secure it.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-3 As shown in the figure, this utility model embodiment proposes a construction safety early warning alarm device, including an adjusting rod 1. The adjusting rod 1 includes a supporting outer rod 11 and a sliding inner rod 12 slidably sleeved within the supporting outer rod 11. The supporting outer rod 11 and the sliding inner rod 12 can change their relative positions by sliding, thereby adjusting the length of the adjusting rod 1. The supporting outer rod 11 is provided with a locking mechanism that can fix the sliding inner rod 12. In this embodiment, the locking mechanism includes a plurality of limiting holes 111 and a top rod 121. The plurality of limiting holes 111 are equidistantly arranged along the axial direction on the side wall of the supporting outer rod 11. The top rod 121 is elastically telescopically arranged on the sliding inner rod 12. Specifically, a groove is fixedly provided on the sliding inner rod 12, and the bottom of the groove... The top rod 121 is connected to the bottom of the spring 124. The head of the top rod 121 is always outside the groove when the spring 124 is not extended or retracted. It will only extend or retract into the groove when compressed by an external force. The diameter of the limiting hole 111 is larger than the diameter of the top rod 121. Therefore, the top rod 121 will pass through the hole when it coincides with the limiting hole 111, thereby achieving the purpose of locking and limiting the sliding inner rod 12. When the length needs to be adjusted again, the top rod 121 only needs to be pressed into the groove, and the sliding inner rod 12 and the supporting outer rod 11 will slide relative to each other until the top rod 121 coincides with another limiting hole 111. A stabilizing bracket 6 is fixedly provided at the bottom of the supporting outer rod 11, and a power supply 5 is fixedly provided at the top of the sliding inner rod 12.

[0028] Combination Figure 3 and Figure 6As shown, in this embodiment, a sliding groove 112 is further provided axially inside the outer support rod 11, and a guide strip 123 is fixedly provided on the side wall of the inner sliding rod 12. The guide strip 123 can be embedded in the sliding groove 112 and slide relative to it. Based on the above improvement, the inner sliding rod 12 can only slide axially relative to the outer support rod 11 without relative rotation, which makes it easier for the top rod 121 and the limiting hole 111 to slide and overlap, increasing the convenience of operation of this device.

[0029] like Figure 1-2 As shown, in this embodiment, the construction safety early warning alarm device further includes an early warning mechanism, which includes a rotating ring 2 and a sensor. The rotating ring 2 is coaxially rotatably mounted on the sliding inner rod 12. The sensor is rotatably connected to the rotating ring 2 via a universal joint 22. A buzzer 32 connected to the sensor is fixedly mounted on one side. Specifically, a first knob 21 is threadedly connected to one side of the rotating ring 2. The first knob 21 can be screwed into and pressed against the sliding inner rod 12, thereby fixing the sliding inner rod 12. In this embodiment, the universal joint 22 can be configured as a universal ball joint, which includes a spherical shell and an internal stainless steel ball. A second knob 221 that can be screwed into and lock the stainless steel ball is fixedly mounted on the spherical shell. One end of the universal joint 22 is fixedly connected to the rotating ring 2, and the other end is fixedly connected to a support arm 23. A damping turntable 3 is rotatably mounted on the far side of the support arm 23. The damping turntable 3 experiences resistance when rotating, so it is not easy to rotate again after the angle adjustment is completed. The sensor is fixedly mounted on the damping turntable 3. The sensor includes an infrared sensor, a lidar sensor, a microwave radar sensor, or an ultrasonic sensor, as well as other sensing devices that can sense the approach of a human body and provide a sensing signal. In this embodiment, the sensor is set as an infrared sensor 31. The bottom of the infrared sensor 31 is fixedly connected to the damping turntable 3. The buzzer 32 is fixedly mounted on the bottom of the damping turntable 3. The sensor and the buzzer 32 are electrically connected to the power supply 5. Based on the above settings, the infrared sensor 31 can flexibly adjust its position according to the actual working environment. For example, it can rotate circumferentially around the sliding inner tube; it can rotate spherically around the universal joint 22 with the support arm 23 as the radius, realizing stepless adjustment of the sensor's pitch angle and horizontal deflection angle; it can also follow the circumferential rotation of the damping turntable 3, thereby flexibly deploying and accurately calibrating the monitoring range of the infrared sensor 31 according to the complex and ever-changing environment of the construction site, and completing more accurate directional coverage of specific dangerous areas.

[0030] The technical principle of this utility model is as follows: When in use, the device is placed near a dangerous area. The relative positions of the sliding inner rod 12 and the supporting outer rod 11 are adjusted according to the actual situation of the area. The device is then fixed by locking the top rod 121 and the limiting hole 111. That is, the height of the adjusting rod 1 is changed to adapt to the construction environment. Then, the rotating ring 2 is rotated and the rotation angle of the universal joint 22 and the damping turntable 3 is adjusted so that the infrared sensor 31 can rotate at multiple angles to set the optimal monitoring range for the area requiring early warning. When the infrared sensor 31 detects that a person is approaching, it will transmit a signal to the alarm buzzer 32, which will then emit a sound to issue an early warning.

[0031] This invention, through the setting of an adjusting rod 1 consisting of a supporting outer rod 11 and a sliding inner rod 12, and a locking mechanism, can conveniently change the overall height of the device to adapt to working surfaces of different heights, ensuring that the sensor is in the optimal detection position and avoiding the problems of detection blind spots or inability to adapt to changing terrain caused by a fixed height. By setting a rotating ring 2 that can rotate around the sliding inner rod 12 and a universal joint 22 set on the rotating ring 2, the infrared sensor 31 installed on it can be adjusted in the horizontal direction, which can adjust the horizontal monitoring range, flexibly align with irregular dangerous boundaries or avoid fixed obstacles on site, effectively reducing detection blind spots. The universal joint 22 allows the sensor to be freely adjusted in the vertical direction and tilt angle, enabling the device to be flexibly deployed and accurately calibrated according to the complex and changing environment of the construction site, and can provide more precise directional coverage of specific dangerous areas, significantly improving the accuracy and reliability of early warning and reducing the occurrence of safety accidents.

[0032] like Figure 4 As shown, according to another embodiment, the locking mechanism further includes a tightening bolt 113, which is threaded onto the outer support rod 11. The tightening bolt 113 can be screwed into and abut against the inner sliding rod 12. Through the above improvements, the relative positions of the outer support rod 11 and the inner sliding rod 12 can be adjusted more flexibly, and the adjustment is more precise and convenient.

[0033] like Figure 1-5As shown, according to another embodiment, further, a movable rod 4 is coaxially rotatably provided on the top of the sliding inner rod 12. Preferably, the movable rod 4 is sleeved inside the sliding inner rod 12, and a clamping knob 122 is threadedly connected to the side wall of the sliding inner rod 12. The clamping knob 122 can be screwed into and clamp the movable rod 4. A plurality of warning rods 41 are detachably provided on the side wall of the movable rod 4. Specifically, a plurality of threaded holes 44 are provided on the side wall of the movable rod 4, and a threaded head 43 is fixedly connected to one side of each warning rod 41. The threaded head 43 can engage with the threaded hole 44. A long warning light 42 is fixedly installed on the warning rod 41. The warning light 42 is electrically connected to the power supply 5. The warning light 42 can emit red or blue warning light at night to remind passersby to pay attention to safety. Reflective strips and other items that can have a warning effect can also be attached to the warning rod 41. The length and number of the warning rods 41 can be selected according to the actual situation, and the direction in which the warning rods 41 face can be adjusted by rotating the movable rod 4 to further increase the applicability of this device.

[0034] like Figure 1-5 As shown, according to another embodiment, further, a solar panel 51 is rotatably mounted on the top of the movable rod 4, and a power supply 5 is fixedly mounted on the top of the movable rod 4 and electrically connected to the solar panel 51. Specifically, an adjusting shaft 52 is rotatably mounted coaxially with the movable rod 4 on the top of the power supply 5. A third knob 521, which can be screwed into and pressed against the adjusting shaft 52, is also threadedly connected to one side of the top of the power supply 5. A mounting bracket 53 is fixedly connected to the bottom of the solar panel 51. The mounting bracket 53 is hinged to the adjusting shaft 52. A fourth knob 531, which can be screwed into and pressed against the mounting bracket 53, is threadedly connected to the hinge of the mounting bracket 53 and the adjusting shaft 52. Based on the above configuration, the solar panel 51 can adjust its panel orientation at multiple angles, so that it can adapt to different latitudes of sunlight.

[0035] like Figure 6-7As shown, according to another embodiment, further, the stabilizing bracket 6 includes a plurality of supporting legs 61, the number of supporting legs 61 being greater than three. In this embodiment, the number of supporting legs 61 is set to three. The supporting legs 61 surround the supporting outer rod 11 and are hinged to its bottom. A stabilizing foot 62 is rotatably provided at the bottom of the supporting leg 61. The stabilizing foot 62 is used to increase the contact area with the ground, thereby increasing the stability of the device when placed on the ground. The stabilizing foot 62 can adaptively adjust its angle with the ground according to the degree of ground inclination to maximize contact with the ground. The foot support 62 is threadedly connected to a fifth knob 611 on one side, which can be tightened and fixed. When the angle of the stabilizing foot support 62 is adapted to the ground, the fifth knob 611 can be used to tighten and fix the stabilizing foot support 62. Folding plates 622 are fixedly provided on both sides of the stabilizing foot support 62. The folding plates 622 can be rotated to fit tightly against the sides of the support legs 61 to increase the aesthetics when stored and reduce the space occupied. A through hole 621 is provided in the middle of the stabilizing foot support 62. The through hole 621 allows expansion bolts or steel nails to be inserted and embedded in the ground, so that the device can be installed more stably next to the warning area.

[0036] like Figure 6-7 As shown, further, a stabilizing rod 63 is coaxially fixed at the bottom of the supporting outer rod 11. A first sliding sleeve 64 is slidably sleeved on the stabilizing rod 63, and a second sliding sleeve 65 is slidably sleeved on the supporting leg 61. The first sliding sleeve 64 and the second sliding sleeve 65 are hinged together by a connecting rod 66. The first sliding sleeve 64 is hinged to the second sliding sleeve 65 by the connecting rod 66, so that the supporting leg 61 will open and close synchronously, further increasing its stability when supporting and its convenience when storing.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
