Description

Technical Field

[0001] This utility model relates to the field of power facility protection technology, and in particular to a conductor protection device based on Beidou positioning and electromagnetic detection. Background Technology

[0002] With the development of modern industry, large-scale machinery and equipment play an important role in construction and other fields. However, because these devices are usually large in size and have limited visibility, there is a risk of contact with power transmission lines during operation, which may lead to line damage or even safety accidents.

[0003] Existing preventative measures rely primarily on the experience and visual judgment of operators, which poses certain safety risks. Therefore, it is necessary to provide a device that can effectively prevent large machinery from coming into contact with power transmission lines during operation to change this situation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conductor protection device based on BeiDou positioning and electromagnetic detection. Its advantage lies in its ability to promptly send an alarm to the platform when equipment is detected approaching the safe distance of the transmission line, thereby significantly improving the safety of the work site.

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

[0006] A conductor protection device based on BeiDou positioning and electromagnetic detection includes a housing, an internal 4G antenna, and a GNSS antenna on one side of the top of the housing. The GNSS antenna is used to receive signals from BeiDou satellites and can obtain precise location information of mechanical equipment in real time. An electromagnetic detection antenna is provided on the other side of the top of the housing to reduce the obstruction of the GNSS antenna signal by the surrounding environment.

[0007] The device housing has an LCD screen on the front. A power switch and a calibration button are located on the outer wall of the device housing below the LCD screen. The power switch is located between the calibration button and the LCD screen. The device also includes two batteries. Both batteries are connected to the device housing via power cords and are used to power the device.

[0008] Using the above technical solution: During use, the equipment is fixed to the boom of the work vehicle. The power switch is pressed, and the power indicator light illuminates, indicating that the equipment has started. Next, the operator presses the calibration button, and the equipment enters coordinate calibration mode. The GNSS antenna is calibrated multiple times at different points, and the equipment records the coordinates of each calibration point. The area enclosed by these coordinate points is the fenced working area. After the equipment starts, the 4G antenna begins searching for and connecting to the server. Once the connection is successful, the communication status indicator light remains on. The 4G antenna interacts with the differential server to obtain high-precision differential positioning data. At this time, the RTK status indicator light remains on. The 4G antenna sends the differential positioning data to the server. After receiving the data, the server compares the equipment's real-time location with the preset fenced working area to determine if the equipment exceeds the warning standard. When the on-site machinery leaves the safe working area fence, the vehicle-mounted terminal's audible and visual alarm device will sound an alarm, informing the operator that they have exceeded the safe working area and prompting them to immediately return to the safe working area.

[0009] The present invention is further configured such that the outer shell of the device is made of ABS material.

[0010] Through the above technical solutions, the ABS material used for the equipment casing has good electromagnetic wave penetration and electrical insulation, ensuring the signal transmission efficiency of the built-in 4G antenna.

[0011] The present invention is further configured such that the outer shell of the device is composed of a first shell and a second shell, and a sealing ring is provided at the connection gap between the first shell and the second shell.

[0012] Through the above technical solutions, the seams and interfaces of the equipment shell are all sealed with sealing rings to ensure waterproof and dustproof protection and adaptability to harsh environments.

[0013] The present invention is further provided that the front of the device housing is provided with multiple status indicator lights, including a power status indicator light, an RTK status indicator light, and a communication status indicator light.

[0014] The above technical solutions enable users to judge the operating status of the equipment by displaying the power status indicator, RTK status indicator, and communication status indicator, respectively, to indicate whether the power status, differential positioning status, and 4G network status are normal.

[0015] The present invention is further configured such that magnets are connected to both the device housing and the back of the battery via a fixing mechanism.

[0016] The above technical solution, with its magnets, allows for easy attachment of the equipment and battery to the boom of the work vehicle, improving installation convenience.

[0017] The present invention is further configured such that the fixing mechanism includes a magnet fixing frame, the magnet fixing frame has a U-shaped cross-section, two fixing plates are slidably connected inside the magnet fixing frame, the fixing plates have an L-shaped structure, fixing bolts are threadedly connected to both sides of the magnet fixing frame, the fixing bolts are rotatably connected to the fixing plates, and the magnet is located between the two fixing plates.

[0018] With the above technical solution, when installing the magnet, simply rotate the fixing bolt. The rotation of the fixing bolt causes the two fixing plates to move relative to each other, clamping and fixing the magnet, which improves the convenience of magnet installation and disassembly.

[0019] The present invention is further configured such that the surface of the battery is provided with a plurality of power indicator lights, the number of power indicator lights lit representing the level of battery power.

[0020] The above technical solution includes a power indicator light that displays the battery level, allowing staff to charge the equipment promptly when the battery is low.

[0021] The beneficial effects of this utility model are as follows: When using the wire protection device for Beidou positioning and electromagnetic detection, the device is fixed on the boom of the working vehicle, the power switch is pressed, and the power indicator light is lit, indicating that the device has been started. Then, the operator presses the calibration button, and the device enters the coordinate calibration mode. The GNSS antenna is calibrated multiple times at different points, and the device records the coordinates of each calibration point. The area enclosed by these coordinate points is the fence working area.

[0022] The 4G antenna begins searching for and connecting to the server. Once connected, the communication status indicator light stays on. The 4G antenna interacts with the differential server to obtain high-precision differential positioning data; at this time, the RTK status indicator light remains on. The 4G antenna sends the differential positioning data to the server. After receiving the data, the server compares the device's real-time location with the preset fenced work area to determine if the device exceeds the warning standard. When the on-site machinery leaves the safe working area fence, the vehicle-mounted terminal's audible and visual alarm device will sound an alarm, informing the operator that they have exceeded the safe working area and prompting them to immediately return to the safe working area. It can monitor the relative distance between the top of the large work vehicle's boom and the sag of the power transmission line in real time. When the electromagnetic detection module detects that the electromagnetic field strength is lower than the set electromagnetic field strength threshold, the Beidou positioning module is less affected by the magnetic field, and the handheld terminal uses the Beidou positioning module's data for judgment and audible and visual warnings. When the electromagnetic detection module detects that the electromagnetic field strength is higher than the set electromagnetic field strength threshold, the device will use the electromagnetic detection module's data for judgment and audible and visual warnings to infer the relative distance. This significantly improves the safety of the work site. Attached Figure Description

[0029] Reference Figure 1-3 A wire protection device based on BeiDou positioning and electromagnetic detection includes a housing 1, with a 4G antenna installed inside the housing 1. The device is characterized by having a GNSS antenna 2 installed on one side of the top of the housing 1. The GNSS antenna 2 is used to receive signals from BeiDou satellites and can obtain precise location information of mechanical equipment in real time. An electromagnetic detection antenna 3 is installed on the other side of the top of the housing 1. The electromagnetic detection antenna 3 is used to reduce the obstruction of the GNSS antenna 2 signal by the surrounding environment.

[0030] The device housing 1 has an LCD screen 4 on its front side. A power switch 5 and a calibration button 6 are respectively provided on the outer wall of the device housing 1 below the LCD screen 4. The power switch 5 is located between the calibration button 6 and the LCD screen 4. The device housing 1 also includes two batteries 8. The two batteries 8 are connected to the device housing 1 through a power cord 10. The batteries 8 are used to power the device.

[0031] The equipment can also monitor the relative position of the boom of the working vehicle and the power transmission line in real time. The equipment has an electromagnetic detection antenna 3 built in. Once the electromagnetic detection antenna 3 detects an abnormal change in the electromagnetic field strength near the equipment, the system will take early warning measures. At this time, the equipment will return the early warning data to the platform in real time and issue an alarm to the operator through the sound and light alarm device of the vehicle terminal, reminding them that the equipment is too close to the power transmission line and that they should control the height of the boom of the working vehicle in time to maintain a safe distance from the power transmission line.

[0032] In this embodiment, the device housing 1 is made of ABS material. The ABS material of the device housing 1 has good electromagnetic wave penetration and electrical insulation, which ensures the signal transmission efficiency of the built-in 4G antenna.

[0033] The equipment housing 1 is composed of a first housing and a second housing. A sealing ring is provided at the connection gap between the first housing and the second housing.

The fixing bolts 14 are rotatably connected to the fixing plates 12. The magnet 11 is located between the two fixing plates 12. When installing the magnet 11, simply rotate the fixing bolts 14. The rotation of the fixing bolts 14 causes the two fixing plates 12 to move relative to each other, clamping and fixing the magnet 11, thus improving the ease of installation and removal of the magnet 11.

[0036] It is worth mentioning that the surface of the battery 8 is equipped with several power indicator lights 9. The number of lit power indicator lights 9 indicates the battery level of the battery 8. The power indicator lights 9 can display the battery level of the battery 8, making it convenient for staff to charge the equipment in time when the power is low.

[0037] Working Principle: During use, fix the device to the boom of the work vehicle and press power switch 5. The power indicator light will illuminate, indicating that the device has started.

GNSS antenna 2 performs multiple calibrations at different points, and the device records the coordinates of each calibration point. The area enclosed by these coordinate points is the fenced working area. After the device starts, the 4G antenna begins searching and connecting to the server. After successful connection, the communication status indicator light stays on. The 4G antenna interacts with the differential server to obtain differential high-precision positioning data.
