Description

Technical Field

[0001] This invention relates to the field of electromagnetic information acquisition technology, specifically to an electromagnetic information acquisition and filtering device with protective functions. Background Technology

[0002] An electromagnetic information acquisition and filtering device with protective functions is used to collect, process, and display electromagnetic environment information. Among them, electric field sensors and magnetic field sensors are used to collect electric field and magnetic field strength. The data acquisition and processing unit completes the filtering and processing of electric field, magnetic field strength, DC power grid conducted emission, AC power grid conducted emission, and spike pulse data, and uploads them to the host computer for comprehensive analysis, display, and human-computer interaction.

[0003] In existing technologies, electric field sensors can detect and rectify received electric field signals into DC. This requires the sensor to have a certain frequency response flatness in the 10kHz–400MHz range to ensure accurate detection results. Simultaneously, the electric field signal is weak, requiring the noise floor of the sensor's processing circuitry to be controlled within a certain range, making it much smaller than the useful signal. Due to varying installation and usage environments, the fixed-size housing of conventional electromagnetic information acquisition and filtering devices with protective functions cannot adequately adapt to different installation environments and is prone to damage during impacts. Therefore, it is necessary to invent an electromagnetic information acquisition and filtering device with protective functions to solve these problems. Summary of the Invention

[0028] Example 2:

[0029] Please see Figure 5-6 Furthermore, in conjunction with Embodiment 1, the auxiliary limiting mechanism 10 includes a connecting cylinder 101, which is fixedly connected to the top of the mounting base 1. A rod 102 is inserted into the inside of the connecting cylinder 101, and a second spring 104 is fixedly connected to the outside of the connecting cylinder 101. A connecting sleeve 103 is fixedly connected to the top of the second spring 104, and a limiting ball 105 is movably connected inside the connecting cylinder 101. This facilitates the rapid installation between the rod 102 and the connecting cylinder 101, thereby meeting the needs for adjusting and installing for different filtering interference requirements.

[0030] Furthermore, the connecting sleeve 103 is slidably connected to the connecting cylinder 101.

[0031] Example 3:

[0032] Please see Figure 7-8Furthermore, in conjunction with Embodiment 1 and Embodiment 2, it is further found that the adjusting clamping mechanism 11 includes a connecting platform 111, which is fixedly connected to the top of the insertion rod 102. A bidirectional threaded rod 112 is rotatably connected inside the connecting platform 111. A limiting rod 115 is fixedly connected inside the connecting platform 111. A movable block 113 is slidably connected to the outside of the limiting rod 115. A clamping plate 114 is fixedly connected to the top of the movable block 113, which facilitates the adjustment of the position of the clamping plate 114, thereby satisfying the clamping and limiting of connecting lines of different sizes.

[0033] Furthermore, the movable block 113 is threadedly connected to the bidirectional threaded rod 112, and the connecting platform 111 and the movable block 113 are provided with grooves at corresponding positions, and the movable block 113 is slidably connected inside the groove, which facilitates a more stable limiting process.

[0034] In actual operation, when this device is used, the internal components of the acquisition filter 3 include a standard 50Hz filter module, electric field sensor, electric field connector, magnetic field sensor, magnetic field connector, annular copper tube, AC grid conductive transmitter, DC grid conductive transmitter, DC connector, current probe, capacitor, and discharge resistor mechanism. After the operator moves the device to the designated location, adjustments are made according to the pre-drilled mounting holes in the installation environment. The operator rotates the worm gear 911, which, in conjunction with the worm wheel column 912, causes the limiting plate 913 to rotate, cooperating with the limiting column 916, allowing the mounting bracket 915 to slide within the slide rail 914, thereby adjusting the position of the mounting bolt 917. After installation, the operator installs the relevant electrical connection devices using connecting wires. Adjustments are made according to the required filtering interference. The operator pulls the connecting sleeve 103, which, in conjunction with the second spring 104, causes the limiting ball 105 to move along the connecting... The connecting sleeve 103 moves along the inclined groove. After inserting the insertion rod 102 into the connecting cylinder 101, the connecting sleeve 103 is released. Under the action of the second spring 104, the limiting ball 105 moves until it contacts and limits the insertion rod 102. Then, the connecting wire is placed inside the clamping plate 114. The operator uses a hex wrench or other tools to rotate the bidirectional threaded rod 112. The rotation of the bidirectional threaded rod 112, in conjunction with the limiting rod 115, causes the movable block 113 to move, thereby moving the clamping plate 114 until it clamps the connecting wire. When the acquisition filter 3 is compressed or collided, the protective plate 923 moves, causing the slider 922 to slide inside the connecting box 921, thereby moving the first fixed block 924. In conjunction with the connecting rod 9210, the second fixed block 929 moves, and in conjunction with the damping rod 927 and the first spring 926, the slide plate 928 slides outside the slide rod 925. This provides buffering and shock absorption when the acquisition filter 3 is compressed or collided, preventing damage to the acquisition filter 3.
