[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0045] Example 1: Figures 1-8 As shown, the present invention provides a portable warning enclosure device for power maintenance personnel, comprising:

[0046] Support unit 101: A polygonal frame formed by connecting at least three carbon fiber telescopic rods;

[0047] The polygonal frame is constructed using lightweight and high-strength carbon fiber telescopic rods to achieve portability with a device weight of ≤3kg. The carbon fiber density is 1.6g / cm 3 , tensile strength ≥3500MPa, while ensuring the frame's wind load resistance ≥ level 8, and the polygonal structure disperses stress; the modular splicing design supports rapid deployment and rapid expansion, adapting to the strict timeliness requirements of power repair sites.

[0048] Composite alarm module 201: integrated on the top of the support unit 101, used for electromagnetic wave detection and danger warning and alarm;

[0049] The composite alarm module 201 can be used to remind passers-by through various means such as sound alarms and pattern warnings. The work site can be detected through electromagnetic wave detection, and the risk of magnetic leakage of high-voltage equipment can be captured in real time.

[0050] Adaptive counterweight assembly 301: located at the bottom of the support unit 101, comprising a magnetic fluid dynamic counterweight chamber 303 and a terrain pressure feedback unit 304;

[0051] The magnetic fluid dynamic counterweight tank 303 is combined with the terrain pressure feedback unit 304 to achieve dynamic matching of the counterweight distribution and the ground bearing characteristics, ensuring the stability of the device on loose soil or inclined ground (slope ≤ 15°).

[0052] Electromagnetic shielding connecting belt 401: uses a multi-layer conductive fiber woven structure to connect the support units 101, and is connected to an electric field strength indicator 404 for real-time monitoring of the electric field strength;

[0053] Suppress the electric field strength in the working area to a safe threshold; the real-time electric field strength indicator function realizes visual monitoring of the electromagnetic environment, assisting personnel to quickly locate areas with abnormal field strength;

[0054] Intelligent environment perception module 501: embedded in the support unit 101, including a three-dimensional vibration monitoring unit 502, a microwave displacement monitor 503 and an electric field gradient analysis unit 505.

[0055] The three-dimensional vibration monitoring unit 502 (accelerometer sensitivity ±2g) works in conjunction with the microwave displacement monitor 503 (ranging accuracy ±1cm) to identify objects weighing 5kg or more intruding into the protection zone and trigger an alarm (response time ≤0.5 seconds). The electric field gradient analysis unit 505 (sampling rate 1kHz) constructs a three-dimensional field intensity distribution model and predicts the arc development path with an accuracy of ≥85%.

[0056] As a technical optimization solution of the present invention, the adaptive counterweight assembly 301 includes: a terrain pressure feedback unit 304 for terrain contact surface distribution, which detects the ground bearing pressure distribution;

[0057] The magnetic fluid dynamic counterweight chamber 303 is provided with magnetic fluid.

[0058] As a technical optimization solution of the present invention, a magnetic plate 306 for adjusting the distribution of magnetic fluid is provided on the top of the magnetic fluid dynamic counterweight bin 303. A track groove for adjusting the movement of the magnetic plate 306 is opened on the upper surface of the magnetic fluid dynamic counterweight bin 303. A second hydraulic cylinder 307 is fixedly provided in the track groove.

[0059] The second hydraulic cylinder 307 is a double-headed hydraulic cylinder, and the telescopic end of the second hydraulic cylinder 307 is connected to the guide block extending from the adjustment magnetic plate 306 to the inside of the track groove.

[0060] A first hydraulic cylinder 308 is fixedly provided on the upper surface of the magnetic fluid dynamic counterweight chamber 303 , and the middle portion of the first hydraulic cylinder 308 is connected to the middle portion of the second hydraulic cylinder 307 through a high-pressure pipe.

[0061] A group of adjusting magnetic pieces 306 are pushed by the telescopic end of the second hydraulic cylinder 307 and move to the same side at the same time. During this process, the adjusting magnetic pieces 306 can drive the magnetic fluid inside the magnetic fluid dynamic counterweight bin 303 to move synchronously through magnetism. At this time, the weight on one side of the magnetic fluid dynamic counterweight bin 303 will increase, and the adjusting magnetic pieces 306 will be moved toward the upwind side according to the wind direction. The stability of the carbon fiber telescopic rod can be increased by changing the counterweight of the magnetic fluid dynamic counterweight bin 303. Both the adjusting magnetic pieces 306 and the magnetic fluid can play the role of counterweight, and the purpose of dynamic adjustment is achieved by driving the magnetic fluid to move by adjusting the magnetic pieces 306.

[0062] There are two second hydraulic cylinders 307, each corresponding to a first hydraulic cylinder 308; when the two telescopic ends of the first hydraulic cylinder 308 are compressed at the same time, the hydraulic oil in the first hydraulic cylinder 308 will enter the corresponding second hydraulic cylinder 307 through the high-pressure pipe. When the corresponding second hydraulic cylinder 307 is telescoped and extended, it will push a group of adjusting magnetic plates 306 to move synchronously.

[0063] As a technical optimization solution of the present invention, a protruding bracket 103 is fixedly provided on the side wall of the carbon fiber telescopic rod, and a rotating block 104 is rotatably provided at one end of the protruding bracket 103 away from the carbon fiber telescopic rod for fixing the magnetic sheet 105;

[0064] The multiple groups of magnetic sheets 105 connected to the side walls of the carbon fiber telescopic rod are arranged flush with each other.

[0065] The lower surface of a group of rotating blocks 104 placed at the lower end of the carbon fiber telescopic rod is fixedly connected to the rotating rod 106, and the lower end of the outer wall of the rotating rod 106 is fixedly connected to the pressing block 309, which contacts the telescopic end of the first hydraulic cylinder 308.

[0066] The flush arrangement of multiple groups of magnetic sheets 105 can facilitate the connection of the electromagnetic shielding connecting belt 401. When the electromagnetic shielding connecting belt 401 is blown by external wind, the wind will push the electromagnetic shielding connecting belt 401. During this process, the rotating block 104 will rotate with the protruding bracket 103. During the rotation process, the group of rotating blocks 104 placed at the lower end will drive the rotating rod 106 to rotate. The rotation of the rotating rod 106 can squeeze the telescopic end of the first hydraulic cylinder 308, thereby realizing the reverse direction push of the adjusting magnetic sheet 306, and can realize adaptive adjustment of the adjusting magnetic sheet 306 according to the thrust of the wind.

[0067] When the wind is strong, the electromagnetic shielding connecting belt 401 will be subjected to a large thrust. The end of the electromagnetic shielding connecting belt 401 is connected to the magnetic sheet 105, and the electromagnetic shielding connecting belt 401 can drive the magnetic sheet 105 to rotate. The angle of the rotating block 104 driven by the magnetic sheet 105 is affected by the wind force and the slope inclination angle. The stronger the wind, the greater the rotation angle of the rotating block 104. At this time, the magnetic fluid in the magnetic fluid dynamic counterweight bin 303 moves in the opposite direction of the rotation of the rotating block 104 when adjusting the movement of the magnetic sheet 306, thereby achieving the distribution of the center of gravity of the magnetic fluid dynamic counterweight bin 303, ensuring the stability of the environment for power maintenance personnel during work, and preventing the electromagnetic shielding connecting belt 401 from shaking. Dynamic compensation for frame tilt caused by wind and external force disturbances.

[0068] Example 2: basically the same as Example 1, such as Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the difference is that the electromagnetic shielding connection belt 401 includes:

[0069] The built-in shielding layer 402 has a three-layer composite structure, the outer layer is a conductive fiber woven mesh 403, the middle layer is a ferrite absorbing layer, and the inner layer is a flexible insulating substrate;

[0070] The three-layer composite structure has a shielding effectiveness of ≥40dB at a field strength of 10kV / m, while maintaining flexibility with a bending radius of ≤5cm. The conductive fiber braided mesh 403 (surface resistance ≤0.1Ω / sq) and the ferrite absorbing layer (attenuation ≥30dB in the frequency band 100kHz-3GHz) form a composite shield.

[0071] The electric field strength indicator 404 has an outer layer of the conductive fiber woven mesh 403, and displays the electric field strength gradient of 0-50 kV / m through LED color changes.

[0072] The electric field strength indicator 404 sends real-time electric field strength data and warning information to the maintenance personnel terminal through the Bluetooth module. The LED color change display can show the electric field strength gradient more intuitively through color observation, which is convenient for staff to make faster judgments.

[0073] As a technical optimization solution of the present invention, the end of the electromagnetic shielding connecting belt 401 is fixedly connected to an electromagnetic lock buckle 406, which is adsorbed by the magnetic suction plate 105 after being energized; the electromagnetic lock buckles 406 at both ends of the electromagnetic shielding connecting belt 401 generate an adsorption force of ≥50N when energized, and automatically separate after power is cut off.

[0074] After the electromagnetic lock 406 is powered on, it is convenient and quick to connect with the magnetic sheet 105. The electromagnetic lock 406 is independently provided with a power switch, which can quickly connect with the corresponding magnetic sheet 105.

[0075] After power is turned on, the tensile strength is ≥500N (more than 1.5 times the wind load of level 8), and the separation force is ≤5N when the power is off, avoiding structural constraints during emergency evacuation.

[0076] As a technical optimization solution of the present invention, the composite alarm module 201 includes an electromagnetic field detection unit 202, a directional sound wave alarm 203 and a ground projection warning device 205, and the electromagnetic field detection unit 202, the directional sound wave alarm 203 and the ground projection warning device 205 are all connected to the top of the carbon fiber telescopic rod;

[0077] The ground projection warning device 205 supports dynamic generation of radiation area boundary lines and safety channel signs, and stores warning graphics and texts in multiple languages.

[0078] The directional acoustic alarm 203 has a built-in noise suppression module, which automatically enhances the acoustic frequency to 4-6kHz when the ambient noise is greater than 70dB;

[0079] The electromagnetic field detection unit 202 has an accuracy of 0.1μT (the power frequency magnetic field detection range covers the 0.1Hz-1GHz frequency band). It can detect multiple frequency bands and capture the magnetic leakage risk of high-voltage equipment in real time.

[0080] The directional acoustic alarm 203 (sound pressure level ≥90dB@1m) and the ground-projected warning device 205 (projection resolution 1280×720) form a three-dimensional warning system, enhancing awareness for personnel outside the work area and reducing the risk of accidental entry by ≥60%. The ground-projected warning device 205 includes pre-set warning graphics in at least eight languages, providing timely warnings to passersby.
