Description

Technical Field

[0001] This utility model belongs to the field of high voltage alarm technology, specifically relating to a near-high voltage remote early warning alarm device. Background Technology

[0002] In today's power operations and related construction scenarios, near-high voltage remote early warning alarms play a crucial role, as they are related to personnel safety and stable equipment operation. With the acceleration of urbanization and the widespread laying of power facilities, work activities around high-voltage lines are becoming increasingly frequent. When equipment such as cranes, aerial work platforms, and power maintenance vehicles are working near high-voltage lines, a slight oversight may cause serious electric shock accidents, which not only endanger the lives of workers but also affect the normal power supply of the power system, resulting in huge economic losses and social harm.

[0003] Currently, there are various types of near-high voltage remote early warning alarms on the market. Some products use the principle of electromagnetic induction, which uses sensors to detect changes in the electric field around the high voltage line. When the detected electric field strength exceeds the set threshold, an early warning signal is issued.

[0004] However, existing high-voltage remote early warning alarms generally have a significant limitation: the detection direction of the sensors is relatively fixed, making it difficult to effectively monitor pedestrians approaching from all directions. Most early warning alarms can only react to pedestrians approaching the high-voltage line from directly in front or from a specific direction. In some complex working environments, pedestrians may approach the high-voltage line area from various directions, such as in urban construction sites. The surrounding environment is complex and the direction of personnel flow is diverse. Early warning alarms with fixed-direction detection are prone to monitoring blind spots and cannot detect pedestrians approaching the high-voltage line from other directions in time, resulting in untimely warnings and greatly increasing the risk of electric shock to pedestrians.

[0005] In summary, existing near-high voltage remote early warning alarm devices have significant shortcomings in their comprehensiveness in monitoring the direction of pedestrian approach. Utility Model Content

[0006] The purpose of this invention is to provide a near-high voltage remote early warning alarm that can rotate flexibly and detect pedestrians approaching high voltage lines from almost all directions and issue timely warnings, effectively eliminating monitoring blind spots and greatly reducing the risk of electric shock to pedestrians.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A near-high voltage remote early warning alarm includes a fixed block, a rotating frame rotatably connected to the outside of the fixed block, a detection component installed on the outside of the rotating frame, and a drive mechanism for driving the rotating frame to rotate installed inside the fixed block.

[0009] The driving mechanism includes a rotating gear rotatably connected inside the fixed block. A motor is installed inside the fixed block, and the output end of the motor is connected to the rotating gear. A slot is provided on the outer side of the fixed block, and the rotating gear partially passes through the slot and is disposed on the outer side of the fixed block. A ring gear that meshes with the rotating gear is fixed on the inner wall of the rotating frame.

[0010] The diameter of the ring gear is at least twice the diameter of the rotating gear.

[0011] Solar panels are fixed to the top and bottom of the outer side of the rotating frame. A storage battery is installed inside the fixing block, and the storage battery is electrically connected to the solar panel.

[0012] The solar panel is installed at an angle.

[0013] The surface of the solar panel is wave-shaped.

[0014] The outer side of the rotating frame, except for the portion occupied by the detection component and the solar panel, is uniformly provided with pointed cone blocks.

[0015] The technical effects achieved by this utility model are as follows:

[0016] This invention uses a motor to drive a rotating gear, which in turn rotates through the meshing of the rotating gear and the ring gear. This allows the rotating frame and the detection component to rotate, enabling the detection component to rotate flexibly and detect pedestrians approaching high-voltage lines from almost all directions and issue timely warnings. This effectively eliminates blind spots in monitoring and greatly reduces the risk of electric shock to pedestrians. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a near-high voltage remote early warning alarm includes a fixing block 2, which is snapped onto the outside of a cable 1. A rotating frame 3 is rotatably connected to the outside of the fixing block 2, and a detection component 4 is installed on the outside of the rotating frame 3. The detection component 4 includes:

[0025] Electromagnetic sensors are used to detect the intensity of high-voltage electric fields near high-voltage lines or towers.

[0026] A laser rangefinder or ultrasonic sensor is used to measure the actual distance between a pedestrian and the power line.

[0027] The PCB board is used to analyze the conductive electric field strength detected by the electromagnetic sensor and the pedestrian distance detected by the laser rangefinder or ultrasonic sensor, and to determine how many meters away the pedestrian should be from the electric field for safety.

[0028] The system includes a controller and a horn. When a pedestrian approaches and exceeds a set distance, the controller activates the horn to sound an alarm, reminding the pedestrian to stay away.

[0029] In addition, components such as warning lights can be installed to increase the alerting effect on pedestrians;

[0030] Multiple fixing blocks 2 can be installed on a cable 1, thereby enabling the detection and alarm of places frequently traversed by pedestrians along the route;

[0031] The fixed block 2 is equipped with a drive mechanism for driving the rotating frame 3 to rotate.

[0032] See attached document Figure 3 The drive mechanism includes a rotating gear 6 rotatably connected inside the fixed block 2. A motor 5 is installed inside the fixed block 2. The output end of the motor 5 is connected to the rotating gear 6. A slot is provided on the outside of the fixed block 2, and the rotating gear 6 partially passes through the slot and is located on the outside of the fixed block 2. A ring gear 7 that meshes with the rotating gear 6 is fixed on the inner wall of the rotating frame 3.

[0033] When it is necessary to detect the surroundings, the motor 5 can be driven so that the output end of the motor 5 drives the rotating gear 6 to rotate. The rotating gear 6 meshes with the ring gear 7, so that the rotating gear 6 can drive the ring gear 7 and the rotating frame 3 to rotate. The rotating frame 3 drives the detection component 4 to rotate, so that the detection component 4 can rotate to sense almost all directions around it. The diameter of the ring gear 7 is at least twice the diameter of the rotating gear 6, so that the rotation speed of the ring gear 7 is slower, and thus the rotation speed of the detection component 4 is slower. This makes it easier to perform standard scanning of the surrounding scene and pedestrians, and avoids inaccurate scanning due to excessive speed.

[0034] See attached document Figures 3-4 Solar panels 9 are fixed to the upper and lower sides of the rotating frame 3. A battery 8 is installed inside the fixing block 2 and is electrically connected to the solar panel 9. The solar panel 9 can absorb the surrounding sunlight and convert solar energy into electrical energy through the battery 8. This allows the device to generate its own electricity on sunny days and only needs to be powered on cloudy days or when it rains. A conductive ring can be set on the side of the rotating frame 3 to supply power to the device, avoiding the tangling of the power supply wires. Furthermore, the solar panel 9 is set at an angle. This design allows rainwater to flow down the slope when it rains. The surface of the solar panel 9 is wavy, which increases the contact area between the battery 8 and sunlight, thereby increasing the amount of solar energy it absorbs.

[0035] Furthermore, pointed cone blocks are evenly arranged on the outer side of the rotating frame 3, except for the portion occupied by the detection component 4 and the solar panel 9. This arrangement prevents birds from landing on the device when it is not in operation, thereby avoiding damage to the device.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
