Description

Technical Field

[0001] This utility model belongs to the field of power grid construction monitoring technology, specifically relating to a high-voltage proximity audible and visual alarm device. Background Technology

[0002] In high-voltage power construction sites, especially in complex working environments involving various high-voltage live conductors, ensuring a sufficient safe distance between construction machinery and live conductors is crucial. According to relevant standards, there are clear risk control values ​​and safe distance requirements between workers or machinery and live lines and other live conductors. Exceeding these limits can easily lead to serious safety accidents such as electric discharge and electric shock, causing incalculable casualties and property damage.

[0003] Currently, manual monitoring is the primary method used to prevent construction machinery from exceeding safe distances. However, this method has significant drawbacks. Firstly, manual monitoring struggles to accurately determine safe distances, especially in conditions of limited visibility or complex environments, leading to potential misjudgments or oversights by monitoring personnel. Secondly, manual monitoring cannot provide comprehensive real-time monitoring, particularly at night or in inclement weather, where its effectiveness is greatly reduced. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in accurately controlling the safety distance through manual monitoring, which can easily lead to misjudgments or omissions. This invention provides a high-voltage proximity sound and light alarm device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-voltage proximity audible and visual alarm device includes a power supply module and an alarm module connected in parallel across the power supply. The alarm module includes an infrared sensor switch KQ1, an intermediate relay CJ1, a contactor ZJ1, and an audible and visual alarm SG1. The first terminal of the infrared sensor switch KQ1 is connected to the first terminal of the power supply module, the second terminal of the infrared sensor switch KQ1 is connected to the first terminal of the coil of the intermediate relay CJ1, the second terminal of the coil of the intermediate relay CJ1 is connected to the second terminal of the power supply module, the first terminal of the normally open switch of the intermediate relay CJ1 is connected to the first terminal of the power supply module, the second terminal of the normally open switch of the intermediate relay CJ1 is connected to the first terminal of the coil of the contactor ZJ1, the second terminal of the coil of the contactor ZJ1 is connected to the second terminal of the power supply module, the first terminal of the normally open switch of the contactor ZJ1 is connected to the first terminal of the power supply module, the second terminal of the normally open switch of the contactor ZJ1 is connected to the first terminal of the audible and visual alarm SG1, and the second terminal of the audible and visual alarm SG1 is connected to the second terminal of the power supply module.

[0007] The device is installed on the construction machinery at the high-voltage construction site or at a predetermined distance from the high-voltage equipment at the high-voltage construction site.

[0008] A further improvement to this technical solution is that the power module includes several batteries connected in series and a power switch SA1 connected in parallel across the two ends of the batteries, and the alarm module is connected to the batteries through the power switch SA1.

[0009] A further improvement to this technical solution is that the power module also includes a power indicator HD1, which is connected to the battery via a power switch SA1.

[0011] A further improvement to this technical solution is that the alarm module also includes a running indicator light LD1. The first end of the running indicator light LD1 is connected to the first end of the power supply module, and the second end of the running indicator light LD1 is connected to the first end of the infrared sensor switch KQ1. The running indicator light LD1 is mounted on the enclosure.

[0013] Further improvements to this technical solution include the adoption of the SYD220D-3R / 8 audible and visual alarm SG1.

[0014] A further improvement to this technical solution is that the infrared sensor switch KQ1 adopts an infrared sensor switch with model number E3K100-10M.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention uses an infrared sensor switch KQ1 to sense the distance between construction machinery or personnel and live conductors. When the machinery or personnel approach the conductor to within a preset safe distance, the audible and visual alarm SG1 is automatically triggered, emitting a high-decibel sound and a bright light.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] like Figure 1As shown, this utility model provides a high-voltage proximity audible and visual alarm device, including a power supply module and an alarm module connected in parallel across the power supply. The alarm module includes an infrared sensor switch KQ1, an intermediate relay CJ1, a contactor ZJ1, and an audible and visual alarm SG1. The first terminal of the infrared sensor switch KQ1 is connected to the first terminal of the power supply module, the second terminal of the infrared sensor switch KQ1 is connected to the first terminal of the coil of the intermediate relay CJ1, the second terminal of the coil of the intermediate relay CJ1 is connected to the second terminal of the power supply module, the first terminal of the normally open switch of the intermediate relay CJ1 is connected to the first terminal of the power supply module, the second terminal of the normally open switch of the intermediate relay CJ1 is connected to the first terminal of the coil of the contactor ZJ1, the second terminal of the coil of the contactor ZJ1 is connected to the second terminal of the power supply, the first terminal of the normally open switch of the contactor ZJ1 is connected to the first terminal of the power supply module, the second terminal of the normally open switch of the contactor ZJ1 is connected to the first terminal of the audible and visual alarm SG1, and the second terminal of the audible and visual alarm SG1 is connected to the second terminal of the power supply module. This device is installed on construction machinery at a high-voltage construction site or at a preset distance from high-voltage equipment (i.e., a live conductor) at a high-voltage construction site. Reference standards for the preset distance are shown in Tables 1 and 2.

[0026] Table 1: Safety Distances Between Devices Installed at High-Voltage Equipment and Live Parts Based on Different Voltage Levels

[0027]

[0028] Table 2: Safety Distances Between Devices Installed on Construction Machinery and Live Parts Based on Different Voltage Levels

[0029]

[0030] At the construction site, workers can install the device according to Table 1 above. Specifically, based on the voltage level of the live conductors at the construction site, the high-voltage proximity sound and light alarm device is installed at the corresponding safe distance. The sensing threshold of the infrared sensor switch KQ1 in this device is preset to 0.1 meters to 0.5 meters. That is, when construction personnel or construction machinery approach this device and trigger the sound and light alarm SG1, it will remind the construction personnel that they have reached the critical safe distance and should not approach the live conductors.

[0031] Another installation method is to install the device on the construction machinery and set the sensing threshold of the infrared sensor switch KQ1 according to Table 2. When the construction machinery approaches the live part and exceeds the preset sensing threshold, the audible and visual alarm SG1 is triggered to remind the construction personnel that they have reached the critical point of the safe distance and should not approach the live part.

[0032] This invention, by precisely setting the sensing threshold of the infrared sensor switch KQ1 and combining it with the safety distance standards provided in Tables 1 and 2 based on different voltage levels, ensures accurate judgment and early warning of the safe distance between construction machinery or personnel and live conductors at high-voltage construction sites, whether the device is installed at a preset distance from high-voltage equipment or on construction machinery. This significantly improves the accuracy of safety distance control and reduces the risk of safety accidents caused by human error or environmental interference. The device uses the infrared sensor switch KQ1 to detect the presence of surrounding high voltage in real time, and automatically triggers the audible and visual alarm SG1 to emit a high-decibel sound and a strong light alarm when construction machinery or personnel approach a live conductor within the preset safety distance. This automated early warning mechanism requires no manual intervention, can reflect the safety status of the construction site in real time and accurately, and effectively prevents electric shock accidents. Compared with traditional manual monitoring methods, this method greatly improves the accuracy of safety distance control and reduces the risk of safety accidents caused by human error or omission.

[0033] Specifically, the SG1 audible and visual alarm uses the SYD220D-3R / 8 model. The SYD220D-3R / 8 model features high-decibel sound output and a strong flashing light effect, ensuring that the alarm signal is clearly detected by workers in noisy environments at high-voltage power construction sites. It can effectively transmit warning information even at long distances or in poor visibility conditions. This model is designed to meet the needs of complex construction environments such as outdoor substations and transmission line maintenance, possessing excellent waterproof and dustproof performance, and can operate stably in harsh weather conditions, ensuring the reliability of the alarm function. The SYD220D-3R / 8 model has a rapid response capability, issuing an alarm signal within a very short time after detecting high voltage, meeting the 1-second response warning time requirement in the technical solution, effectively protecting the safety of workers and power facilities.

[0034] The KQ1 infrared sensor switch uses the E3K100-10M model. The E3K100-10M model infrared sensor switch features high sensitivity and stability, accurately detecting the safe distance between construction machinery or personnel and live conductors, thus avoiding safety risks caused by human error or environmental interference. This model of infrared sensor switch supports adjustable sensing distance settings, allowing the sensing threshold to be adjusted according to actual construction needs and voltage levels, ensuring accurate early warning at different voltage levels and improving the adaptability and flexibility of the device.

[0035] The power module includes several batteries connected in series and a power switch SA1 connected in parallel across the batteries. The alarm module is connected to the batteries via the power switch SA1. The power module also includes a power indicator light HD1, which is connected to the batteries via the power switch SA1. The handle of the power switch SA1 is mounted on the door of the enclosure (the door is hinged to the enclosure and has a lock). Turning the handle of the power switch SA1 to the closed position: at this time, the internal contacts of the power switch SA1 are connected, and the battery pack outputs power to the alarm module; the power indicator light HD1 illuminates with a stable red light, indicating normal power supply. Turning the handle of the power switch SA1 to the open position: the connection between the battery pack and the alarm module is cut off; the power indicator light HD1 goes out, the device is completely powered off, and battery leakage is prevented; the battery pack can be safely replaced by opening the enclosure door.

[0036] The SA1 power switch provides a physical disconnect point, completely isolating the circuit during maintenance / transportation to prevent accidental triggering. The switch handle is made of insulating engineering plastic (flame retardant rating V0), requiring no tools and preventing electric shock during operation. The HD1 power indicator light, with its red light, directly reflects the power on / off status, preventing device failure due to battery depletion. A silicone sealing ring (IP65 protection rating) is added to the SA1 power switch handle shaft to prevent rainwater ingress.

[0037] In addition, the device includes a cabinet (with a door). The intermediate relay CJ1 and contactor ZJ1 in the power module and alarm module are all housed inside the cabinet. The infrared sensor switch KQ1, audible and visual alarm SG1, power switch SA1, and power indicator HD1 in the alarm module are all located on the cabinet. The exterior of the cabinet is covered with a waterproof layer (an epoxy resin primer and polyurethane topcoat, 80μm thick), silicone sealing strips are embedded at the cabinet seams, and silicone sealant is applied to all exposed component openings to effectively prevent moisture from penetrating into the cabinet and protect the internal components from moisture. The exterior of the cabinet is coated with an anti-corrosion coating to adapt to the high humidity environment of coastal areas.

[0038] By placing key components of the power supply module and alarm module, such as intermediate relay CJ1 and contactor ZJ1, inside the enclosure, these internal components are effectively protected from direct damage from the external environment (such as dust and rain), thus extending the service life of the equipment.

[0039] In addition, the alarm module also includes a running indicator light LD1. The first end of the running indicator light LD1 is connected to the first end of the power supply module, and the second end of the running indicator light LD1 is connected to the first end of the infrared sensor switch KQ1 (that is, the running indicator light LD1 is connected in series between the infrared sensor switch KQ1 and the power disconnect switch SA1). The running indicator light LD1 is installed on the enclosure. When construction machinery or construction personnel approach a live conductor, the running indicator light LD1 and the infrared sensor switch KQ1 form a circuit, illuminating the running indicator light LD1, indicating that the device is operating normally.

[0040] The working principle of this device is as follows: When the device is in use, close the power switch SA1. The HD1 light will illuminate normally, indicating that the power supply is normal. When construction machinery or personnel enter the preset safe distance, the infrared sensor switch KQ1 detects the target and its internal contacts close. The CJ1 coil is energized, and its normally open contact closes (CJ1 isolates the low-voltage sensing circuit (infrared sensor switch KQ1) from the execution circuit (audio-visual sensor SG1) to avoid high-voltage interference). After the CJ1 contact closes, the ZJ1 coil is energized, and the ZJ1 normally open contact closes, providing full power current to the audible-visual alarm SG1. SG1 immediately starts (audio alarm: ≥110dB high-frequency buzzer (covering 120dB ambient noise), visual alarm: red LED flashing (frequency 2Hz, visible distance ≥50 meters)). When the target leaves the safe distance range, KQ1 disconnects, the CJ1 coil is de-energized, the ZJ1 coil is de-energized, and SG1 stops alarming.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
