DETAILED DESCRIPTION

[0032] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1 is the first embodiment of the present application, which provides a method for long-time monitoring of electromagnetic environment in a secret-related field, which comprises the following steps: S1, selecting a suitable place in the secret-related field and fixing the long-time electromagnetic environment monitoring device on the wall; S2, installing the detection mechanism G and detecting electromagnetic signals through the detection mechanism G; S3, transmitting the signals detected by the detection mechanism G to the long-time electromagnetic environment monitoring device and displaying them on the display screen of the long-time electromagnetic environment monitoring device, and storing the detected data; S4, observing the data on the touch screen to determine whether there is electromagnetic signal interference.

[0034] Embodiment 2, refer to Figures 1-9For the second embodiment of the present application, unlike the previous embodiment, the embodiment provides a long-time monitoring device for electromagnetic environment of confidential field, solves the problem of how to automatically prevent dust from entering the joint 11 without using the joint 11, and comprises a monitoring mechanism G, comprising a monitoring component, which comprises an electromagnetic environment monitoring device shell 10, a plurality of joints 11 are arranged at the outer end of the electromagnetic environment monitoring device shell 10, a signal receiver 12 is arranged on the outer side of the electromagnetic environment monitoring device shell 10, the signal receiver 12 is connected with the plug 14 matched with the joint 11 through the adjusting assembly 13; a dustproof component, which comprises a mounting cylinder 20 fixedly connected to the electromagnetic environment monitoring device shell 10, six open grooves 21 are arranged at the upper end of the mounting cylinder 20, the open grooves 21 are provided with a closing assembly 22 for preventing dust from entering the joint 11, a circular ring 23 is rotatably connected to the side wall of the mounting cylinder 20, the circular ring 23 is provided with a transmission assembly 24 for providing power for the closing assembly 22, and the plug 14 is provided with a pushing assembly 25 for providing power for the closing assembly 22; a loosening component, which comprises an elastic assembly 30 arranged on the circular ring 23, and a guide assembly 31 arranged on the circular ring 23 for preventing the circular ring 23 from being automatically reset.

[0035] The electromagnetic environment monitoring device shell 10 is also provided with a touch screen, which can display the monitoring results and can be controlled through the touch screen. The electromagnetic environment monitoring device is a prior art and will not be described here.

[0036] Specifically, the adjusting assembly 13 comprises an extension block 131 arranged at the lower end of the signal receiver 12, a damping rotating shaft 132 fixedly connected to the extension block 131, a connecting column 133 rotatably connected to the plug 14, a containing groove 134 arranged on the connecting column 133, and the damping rotating shaft 132 is rotatably connected with the inner wall of the containing groove 134; the closing assembly 22 comprises six connecting shafts 221 rotatably connected in the six open grooves 21, a rotating block 222 fixedly connected to the connecting shaft 221, a fan-shaped closing plate 223 fixedly connected to the rotating block 222 and closing the upper side of the joint 11, a reference line 224 arranged on the closing plate 223 and the plug 14 for mutual cooperation, a clamping block 225 fixedly connected to the side wall of the closing plate 223, and a clamping groove 226 arranged on the plug 14 for cooperation with the clamping block 225; the curvature of the closing plate 223 is 60°, and the six closing plates 223 are collectively turned to close the upper side of the joint 11.

[0037] Further, the damping shaft 132 is arranged so that it does not automatically rotate, ensuring the stability of the closure plate 223, and the six closure plates 223 have an arc of 60°, which can completely close the upper end of the joint 11, preventing dust from entering and not affecting subsequent use. Meanwhile, the two side walls of the closure plate 223 can be provided with sealing grooves and sealing strips, and the sealing grooves and sealing strips on adjacent two closure plates 223 cooperate to make the sealing effect better. An arc-shaped cutting edge is provided on the side wall of the mounting cylinder 20 to prevent the mounting cylinder 20 from being stuck between the sealing plate when the sealing plate is turned over.

[0038] Preferably, the transmission assembly 24 includes a mounting cavity 241 arranged in the mounting cylinder 20, a sliding block 242 slidably connected in the mounting cavity 241, an arc-shaped opening 243 provided on the side wall of the mounting cylinder 20, a transmission block 244 fixedly connected to the circular ring 23 and matched with the arc-shaped opening 243, the transmission block 244 being fixedly connected with the sliding block 242, a support groove communicated with the mounting cavity 241 provided on the inner wall of the opening groove 21, an L-shaped tooth plate 245 slidably connected in the support groove, a gear 246 rotatably connected to the damping shaft 132 and engaged with the tooth plate 245, a guide opening 247 provided on the tooth plate 245, an inclined edge 248 provided in the guide opening 247 and matched with the sliding block 242, the length of the guide opening 247 being greater than the width of the sliding block 242, and the tooth plate 245 being elastically connected with the inner wall of the mounting cavity 241 through a first spring 249; the pushing assembly 25 includes a first vertical groove 251 arranged on the circular ring 23, an arc-shaped groove 252 communicated on the first vertical groove 251, a second vertical groove 253 communicated on the arc-shaped groove 252, the upper and lower ends of the second vertical groove 253 penetrating the circular ring 23, a fixed ring 254 fixedly connected to the plug 14, two L-shaped plates 255 provided on the fixed ring 254, a push rod 256 fixedly connected to the L-shaped plates 255 and matched with the first vertical groove 251, the arc-shaped groove 252 and the second vertical groove 253, and a limiting strip 257 fixedly connected to the L-shaped plates 255 and matched with the second vertical groove 253.

[0039] It should be noted that the length of the guide hole 247 is greater than the width of the sliding block 242, so that when the sliding block 242 moves to push the gear plate 245 to move, the phenomenon of jamming between the inner wall of the guide hole 247 and the sliding block 242 does not occur. Here, the distance by which the sliding block 242 pushes the gear plate 245 downward is such that the angle of rotation of the rotating block 222 is greater than 110°, thereby ensuring that when the plug 14 is lowered, the sealing plate does not block the plug 14. It should be noted that the fixing ring 254 is fixed to the plug 14 by bolts, so that the fixing ring 254 can be disassembled, and a reference line 224 is also provided on the L-shaped plate 255. When the reference line 224 on the L-shaped plate 255 is opposite to the reference line 224 on the plug 14, it indicates that the installation is accurate. Of course, here it is not limited to the bolt fixing method, and any method that can fix the fixing ring 254 and facilitate the disassembly of the fixing ring 254 can be used.

[0040] In use, the connector 11 is not required to be inserted into the plug 14, and the plurality of sealing plates close the upper side of the connector 11 to prevent dust from entering. When the plug 14 is inserted into the connector 11, the reference line 224 on the plug 14 is opposite to the reference line 224 on the sealing plate 223, or the push rod 256 on the L-shaped plate 255 is opposite to the first vertical slot 251. At this time, the distance between the plug 14 and the mounting cylinder 20 is greater than the length of the sealing plate, and then the plug 14 is moved towards the connector 11, and the push rod 256 is moved into the arc-shaped slot 252. As the push rod 256 continues to move downward, the push rod 256 cooperates with the arc-shaped slot 252 to drive the circular ring 23 to rotate clockwise (as viewed from the direction of the connector 11), drive the transmission block 244 to move, and make the sliding block 242 move towards the gear plate 245. When the sliding block 242 moves towards the gear plate 245, the sliding block 242 cooperates with the inclined edge 248 of the guide hole 247 to drive the gear plate 245 to move downward, the first spring 249 is compressed, the gear 246 is rotated, the damping shaft 132 is rotated counterclockwise (as viewed from the direction of the mounting cylinder 20), the rotating block 222 is rotated counterclockwise, the sealing plate is opened, and the connector 11 is exposed. When the push rod 256 moves in the arc-shaped slot 252, there is still a distance between the plug 14 and the mounting cylinder 20, so that the sealing plate does not block the plug 14 when the plug 14 is lowered;

[0041] When the push rod 256 moves into the second vertical slot 253, the upper end sealing plate of the connector 11 is fully opened, at this time the plug 14 moves towards the connector 11 and allows the connector 11 to be inserted into the interface, in this process, the push rod 256 first moves in the second vertical slot 253, when the push rod 256 is about to leave the second vertical slot 253, the limiting strip 257 cooperates with the second vertical slot 253, so that the circular ring 23 cannot be reset, so that the phenomenon of automatic reset of the sealing plate affecting the insertion of the plug 14 does not occur, when the plug 14 is fully inserted with the connector 11, the limiting strip 257 is separated from the circular ring 23, at this time the toothed plate 245 is reset under the action of the first spring 249, driving the circular ring 23 to reset, the second vertical slot 253 is misaligned with the limiting strip 257, at this time the circular ring 23 blocks the limiting strip 257 from resetting, avoiding the reset of the L-shaped plate 255, ensuring the stability between the plug 14 and the connector 11. It is worth noting that when the toothed plate 245 is reset, the gear 246 is reset to drive the damping shaft 132 to reset, so that the sealing plate is reset. Due to the blocking of the plug 14, the sealing plate cannot be fully reset, and the circular ring 23 cannot be fully reset, at this time the clamping block 225 is inserted into the clamping groove 226, so that the plug 14 cannot automatically rotate or move up and down, further ensuring the stability between the plug 14 and the connector 11.

[0042] In summary, by setting the dustproof component, when the connector 11 is not used, the sealing plate closes the upper side of the connector 11, preventing dust from entering the connector 11 and affecting signal transmission. When the connector 11 is used, the sealing plate is automatically opened by pushing the plug 14, and after the connector 11 and the plug 14 are inserted, the sealing plate automatically flips to allow the clamping block 225 to be inserted into the clamping groove 226, preventing the connector 11 and the plug 14 from loosening.

[0043] Embodiment 3, refer to Figures 1-9 The third embodiment of the present application is different from the previous embodiment, which provides a long-time monitoring device for electromagnetic environment in a confidential field, which solves the problem of how to prevent the plug 14 from being continuously squeezed and deformed. It comprises an elastic assembly 30, which comprises a blocking block 301 fixedly connected to the circular ring 23, a stop block 302 provided on the side wall of the mounting cylinder 20 and cooperating with the blocking block 301, and the blocking block 301 is elastically connected to the stop block 302 through a second spring 303. The blocking block 301 and the stop block 302 are both arranged at the lower end of the circular ring 23, so as not to affect the opening of the sealing plate.

[0044] Further, the guide assembly 31 comprises an inner groove 311 arranged on the inner side wall of the ring 23, an elevating block 312 is slidably connected in the inner groove 311, the elevating block 312 is elastically connected with the inner wall of the inner groove 311 through a third spring, an L-shaped rod 313 is fixedly connected on the elevating block 312, and a first guide groove 314, a second guide groove 315, a third guide groove 316, a fourth guide groove 317 and a fifth guide groove 318 are arranged on the inner side wall of the mounting cylinder 20 and are connected in series and cooperated with the L-shaped rod 313; the concave point 319 is formed between the third guide groove 316 and the fourth guide groove 317, the slope of the third guide groove 316 is greater than that of the fourth guide groove 317, and the fifth guide groove 318 is communicated with the first guide groove 314.

[0045] It should be noted that the slope of the third guide groove 316 is greater than that of the fourth guide groove 317, so that the L-shaped rod 313 is more likely to enter the fourth guide groove 317 from the concave point 319 rather than reset from the third guide groove 316, and when the L-shaped rod 313 is at the concave point 319, the reset of the ring 23 can be avoided, and the sealing plate is prevented from being pressed against the side wall of the plug 14 to cause the deformation of the rubber on the outer side of the plug 14.

[0046] In use, when the push rod 256 cooperates with the arc-shaped groove 252, the ring 23 can be driven to rotate clockwise, and the L-shaped rod 313 is driven to move, at this time, the blocking block 301 pulls the second spring 303, when the limiting strip 257 cooperates with the second vertical groove 253, the L-shaped rod 313 moves from the first guide groove 314 to the second guide groove 315, until it moves to the communication between the second guide groove 315 and the third guide groove 316, when the limiting strip 257 is misaligned with the second vertical groove 253, the ring 23 is reset under the action of the second spring 303, at this time, the L-shaped rod 313 moves to the concave point 319 where the third guide groove 316 and the fourth guide groove 317 are connected, so as to limit the L-shaped rod 313 and avoid the reset of the L-shaped rod 313, at this time, the ring 23 only resets a small segment, so that the clamping block 225 on the sealing plate is just clamped into the clamping groove 226, and the phenomenon that the sealing plate continuously presses the side wall of the plug 14 is avoided, and the deformation of the rubber on the outer side wall of the plug 14 is avoided, when it is necessary to disassemble, the ring 23 is only needed to be rotated clockwise by hand, so that the second vertical groove 253 is opposite to the limiting strip 257, and since the slope of the third guide groove 316 is greater than that of the fourth guide groove 317, the L-shaped rod 313 moves into the fourth guide groove 317, and finally is reset through the fifth guide groove 318, since the fourth guide groove 317 is outside the concave point 319, at this time, the rotational displacement of the ring 23 will drive the sealing plate to open a larger angle through the transmission, and the plug 14 is prevented from being blocked when the plug 14 is pulled out.

[0047] In summary, by setting the anti-loosening component, after the plug 14 is inserted into the connector 11, the resetting of the ring 23 is limited by the L-shaped rod 313 being in the concave point 319, so that the clamping block 225 is just inserted into the clamping groove 226, and the sealing plate does not abut against the plug 14, thereby avoiding the direct extrusion of the plug 14 by the sealing plate, and causing the deformation of the rubber on the outer side of the plug 14.

[0048] It should be noted that the above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
