All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 As shown, this embodiment proposes a sensor fixing device for a lightning peak recorder, including a fixing frame 1, a fixing mechanism 2 for mounting the device is provided on the side wall of the fixing frame 1, and a mounting assembly 3 for mounting the sensor is provided inside the fixing frame 1. like Figure 3As shown, the fixing mechanism 2 includes a first arc-shaped clamp 201 disposed on the side wall of the fixing frame 1. Two first arc-shaped clamps 201 are evenly distributed along the height direction of the fixing frame 1. Adjusting screws 202 are threadedly connected to the side walls of the two first arc-shaped clamps 201. Four adjusting screws 202 are arranged opposite to each other in pairs. A second arc-shaped clamp 203 is threadedly connected to the external thread of the adjusting screw 202. The first arc-shaped clamps 201 and the second arc-shaped clamps 203 are arranged opposite to each other and used in conjunction. A knob 204 is threadedly connected to the end of the adjusting screw 202 away from the second arc-shaped clamp 203. A locking nut 205 is provided at the connection between the adjusting screw 202 and the second arc-shaped clamp 203. A buffer pad 206 is provided on the inner wall of the first arc-shaped clamp 201 and the second arc-shaped clamp 203. A grounding terminal 207 is fixedly connected to the side wall of the first arc-shaped clamp 201. The clamp 201 and the second arc-shaped clamp 203 fit snugly against round or cylindrical objects, increasing the contact area and improving the stability and reliability of the fixation. The adjustable structure design can adapt to objects of different sizes, making it highly versatile. The adjusting screw 202 allows for fine-tuning according to the actual installation situation, ensuring proper tightness. The knob 204 makes operation easier and faster. The locking nut 205 locks the device in place, preventing loosening after adjustment and ensuring long-term stable fixation. The elastic deformation of the buffer pad 206 increases the friction between the clamp and the object, further improving the stability of the fixation. The grounding terminal 207 provides a reliable grounding path, ensuring the electrical safety of the device in lightning environments, preventing damage to the equipment due to overvoltage caused by static electricity or lightning induction, and improving the device's anti-interference capability and safety. In use, rotating the knob 204 drives the adjusting screw 202 to rotate, facilitating adjustment by the operator. This allows for adjustment of the distance between the first arc-shaped clamp 201 and the second arc-shaped clamp 203, thereby clamping or releasing the object being installed and fixing the device. After adjusting the positions of the first arc-shaped clamp 201 and the second arc-shaped clamp 203, tightening the locking nut 205 prevents the adjusting screw 202 from rotating due to vibration or other reasons during use, thus ensuring the stability of the fixation. When clamping the object being installed, the buffer pad 206 undergoes elastic deformation, filling the gap between the clamp and the object and providing a buffering effect. The grounding terminal 207 is connected to the earth, allowing static electricity or lightning-induced current from the device to be introduced into the earth, preventing damage to the device and sensors.

[0020] like Figure 3 and Figure 5As shown, the mounting assembly 3 includes a shielding box 301 housed inside the fixed frame 1. This ensures the accuracy and reliability of the measurement data, prevents external electromagnetic interference from affecting the sensor performance, and improves the device's anti-interference capability. A shielded cable guide 302 is provided on the side wall of the shielding box 301 to maintain the electromagnetic shielding effect of the shielding box 301 while ensuring normal connection of the sensor connection wires, thus ensuring the stability of the sensor signal transmission. An installation plate 303 is located inside the shielding box 301. Several mounting holes 304 are provided on the side wall of the installation plate 303, arranged in a matrix. A lightning peak recording sensor is installed inside each mounting hole 304. The mounting holes 304 arranged in a matrix pattern facilitate orderly installation and management, making the installation more organized and easy to maintain and replace. At the same time, the mounting plate 303 provides stable support, reducing vibration and shaking during operation. A shielding door 306 is provided on the side wall of the shielding box 301. A metal braided strap 307 is provided on the inner wall of the shielding door 306. The end of the metal braided strap 307 away from the shielding door 306 is fixedly connected to the inner wall of the shielding box 301, which facilitates operation inside the shielding box 301. At the same time, the design of the metal braided strap 307 ensures the shielding effect when the metal shielding door 306 is closed, without affecting the overall anti-interference capability of the shielding box 301. In use, the shielding box 301 provides a space for shielding external electromagnetic interference for electronic components such as the lightning peak recording sensor 305, effectively shielding external electromagnetic signals and reducing interference to sensor measurement data. The shielded cable guide 302 is used to pass through the connecting wire of the lightning peak recording sensor 305. The connecting wire enters the interior of the shielding box 301 through the shielded cable guide 302, preventing electromagnetic interference from entering the shielding box 301 through the connecting wire. Several mounting holes 304 arranged in a matrix are opened on the side wall of the mounting plate 303. The lightning peak recording sensor 305 is installed in the mounting holes 304, providing a stable installation position for the sensor. The shielding door 306 facilitates the installation, maintenance, and repair of the internal sensor. The inner wall of the shielding door 306 is provided with a metal braided strap 307. The end of the metal braided strap 307 away from the shielding door 306 is fixedly connected to the inner wall of the metal shielding box 301. When the shielding door 306 is closed, the metal braided strap 307 can ensure the electrical connection between the shielding door 306 and the shielding box 301, maintaining the shielding performance of the shielding box 301.

[0021] like Figure 1 and Figure 5As shown, the shielding box 301 contains a sealed power compartment 4, with an insulating bushing 5 affixed to its inner wall. A lithium battery pack 6 is housed inside the sealed power compartment 4. A lightning data storage module 7 is also housed inside the shielding box 301. A data export interface 8 is located on the side wall of the shielding box 301, and a dustproof and waterproof cover 9 is hinged to the side wall of the data export interface 8. The lithium battery pack 6 is electrically connected to the lightning data storage module 7 and the lightning peak recording sensor 305. In use, the lithium battery pack 6 provides power to the lightning peak recording sensor 305 and the lightning data storage module 7. The lightning data storage module 7 stores the lightning data recorded by the sensor. The data export interface 8 is used to connect to a data cable for external devices, allowing the data stored in the lightning data storage module 7 to be exported to external devices. The hinged dustproof and waterproof cover 9 can be closed when the data export interface 8 is not in use to prevent dust and moisture from entering and protecting it from damage.

[0022] like Figure 1 As shown, the top of the fixed frame 1 is provided with an arc-shaped waterproof cover 10, and the top of the arc-shaped waterproof cover 10 is provided with a water inlet channel 11. Several water inlet channels 11 are evenly distributed along the central axis of the arc-shaped waterproof cover 10. When it rains, rainwater falls on the arc-shaped waterproof cover 10 and flows down quickly along the water inlet channels 11, preventing rainwater from accumulating on the waterproof cover and improving the reliability and service life of the device in harsh weather conditions.

[0023] like Figure 1 and Figure 5 As shown, the shielding box 301 is made of galvanized steel plate, and the inner wall of the shielding box 301 is covered with a copper metal mesh 12. A foam sealing ring 13 is provided on the side wall of the shielding door 306. In use, the galvanized steel plate material and the copper metal mesh 12 on the inner wall can effectively shield external electromagnetic signals and reduce interference with the measurement data of the lightning peak recording sensor 305. When the shielding door 306 is closed, the foam sealing ring 13 undergoes elastic deformation, filling the gap between the shielding door 306 and the shielding box 301, thus sealing the box and preventing dust, moisture and other external substances from entering the interior of the shielding box 301 and protecting the internal electronic components from damage.

[0024] like Figure 3 As shown, an LED indicator group 14 is provided on the side wall of the fixed frame 1. The LED indicator group 14 is electrically connected to the lightning peak recording sensor 305, the lithium battery pack 6, and the lightning data storage module 7. In use, the LED indicator group 14 can display the working status of the device through indicator lights of different colors or flashing frequencies, such as whether the lightning peak recording sensor 305 is working properly, whether the lithium battery pack 6 has sufficient power, and whether the lightning data storage module 7 is storing data properly.

[0025] like Figure 1As shown, the outer surfaces of the fixing frame 1 and the shielding box 301 are coated with an anti-corrosion coating 15, which is made of epoxy resin. During use, the epoxy resin coating exhibits excellent corrosion resistance, forming a protective film on the metal surface to prevent external corrosive substances from entering, effectively preventing the fixing frame 1 and the shielding box 301 from rusting and corroding, and extending the service life of the device.

[0026] Specifically, the sensor fixing device of this lightning peak recorder, when in use: rotating the knob 204 drives the adjusting screw 202 to rotate, facilitating adjustment by the operator. This allows adjustment of the distance between the first arc-shaped clamp 201 and the second arc-shaped clamp 203, thereby clamping or loosening the object being installed, thus fixing the device. After adjusting the positions of the first arc-shaped clamp 201 and the second arc-shaped clamp 203, tightening the locking nut 205 prevents the adjusting screw 202 from rotating due to vibration or other reasons during use, ensuring the stability of the fixing. When clamping the object being installed, the buffer pad 206 undergoes elastic deformation, filling the gap between the clamp and the object and providing a buffering effect. The grounding terminal 207 is connected to the earth, allowing static electricity or lightning-induced current from the device to be conducted to the earth, preventing damage to the device and sensor. (e.g., Figure 3 As shown), the shielding box 301 provides a space for shielding external electromagnetic interference for electronic components such as the lightning peak recording sensor 305. It effectively shields external electromagnetic signals, reducing interference with sensor measurement data. The shielded cable guide 302 is used to thread the connecting wire of the lightning peak recording sensor 305 through the shielded cable guide 302 into the shielding box 301, preventing electromagnetic interference from entering the shielding box 301 through the connecting wire. Several matrix-arranged mounting holes 304 are provided on the side wall of the mounting plate 303. The lightning peak recording sensor 305 is installed in the mounting holes 304, providing a stable mounting position for the sensor. The shielding door 306 facilitates the installation, maintenance, and repair of the internal sensors. A metal braided strap 307 is provided on the inner wall of the shielding door 306. The end of the metal braided strap 307 away from the shielding door 306 is fixedly connected to the inner wall of the metal shielding box 301. When the shielding door 306 is closed, the metal braided strap 307 ensures the electrical connection between the shielding door 306 and the shielding box 301, maintaining the shielding performance of the shielding box 301 (e.g., ...). Figure 3 and Figure 5 As shown), the lithium battery pack 6 provides power to the lightning peak recording sensor 305 and the lightning data storage module 7. The lightning data storage module 7 stores the lightning data recorded by the sensor. The data export interface 8 is used to connect to the data cable of an external device, allowing the data stored in the lightning data storage module 7 to be exported to the external device. The hinged dustproof and waterproof cover 9 can be closed when the data export interface 8 is not in use to prevent dust and moisture from entering the data export interface 8 and protect it from damage (e.g., ...). Figure 1 and Figure 5 As shown), the LED indicator group 14 can display the working status of the device through indicator lights of different colors or flashing frequencies, such as whether the lightning peak recording sensor 305 is working properly, whether the lithium battery pack 6 has sufficient power, and whether the lightning data storage module 7 is storing data properly (e.g., Figure 3 (As shown).
