[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present application are:

[0021] (1) The flexible air bag is sleeved on the outside of the board card main body, and the air port a connected with the inside of the flexible air bag is arranged on the left end wall of the side mounting plate, so that the inside of the flexible air bag can be inflated and deflated through the air port a. By inflating and expanding, the flexible air bag can be wrapped around the outside of the board card main body, effectively improving the probability of damage during storage of the device. At the same time, by deflating and shrinking, the flexible air bag is tightly wrapped around the outside of the board card main body, which can avoid the influence of the existence of the flexible air bag on the normal installation during use of the device, and effectively improve the convenience during use of the device.

[0022] (2) The metal shielding layer is uniformly arranged in the hollow structure inside the flexible air bag, and the metal shielding layer is controlled to be electrified by the micro-control panel, so that the electrified metal shielding layer forms an electromagnetic interference shielding protection on the outside of the board card main body, which is conducive to ensuring the stability of the electronic components inside the board card main body during operation.

[0023] (3) The low-resistance metal layer and the high-permeability metal layer are sleeved to form the metal shielding layer, so that the device can flexibly shield high-frequency electromagnetic interference or low-frequency electromagnetic interference according to the needs of the working environment, which is conducive to ensuring the comprehensiveness of the electromagnetic interference isolation of the device through the metal shielding layer.

[0024] (4) By clamping and installing the insulating diaphragm between the low-resistance metal layer and the high-permeability metal layer, the formation of an electrically conductive circuit between the low-resistance metal layer and the high-permeability metal layer is avoided, which helps to ensure the stability of the device during operation. At the same time, by setting the low-resistance metal layer and the high-permeability metal layer as a grid structure, the overall structural firmness of the flexible air bag can be effectively improved through the connection and pulling of the grid structure, which helps to prolong the service life of the flexible air bag during use.

[0025] (5) By installing the air pump in the inner space of the flexible air bag on the top of the side mounting plate, and connecting the air inlet pipe on the air pump with the air port a, the air pump can actively fill gas into the flexible air bag after being powered on, without the need for external other inflation devices, effectively improving the convenience of the device during use.

[0026] (6) By covering the main air pipe on the top of the board card body, the inflation of the flexible air bag by the air pump can be more rapid and efficient, which helps to improve the convenience of the device during use.

[0027] (7) By installing the air pump on the drive shaft of the micro motor, the rotation position of the air pump can be controlled after the micro motor is powered on, which facilitates flexible docking and conversion between the air outlet pipe, the air inlet pipe, the air passage a and the air passage b. By converting the air outlet pipe and the air inlet pipe, the device can flexibly adjust the direction of air extraction according to the use requirements, and then only a single air pump can complete the air extraction operation inside the flexible air bag, effectively improving the use flexibility of the device. At the same time, by opening the ring groove on the left end wall of the adapter, and extending the air outlet pipe and the air inlet pipe into the ring groove, the rotation of the air pump can be stably limited, which helps to improve the structural stability of the device during adjustment.

[0028] (8) By setting the cross section of the main air pipe as a trapezoidal structure, and opening a through hole in the side end wall of the main air pipe, an airflow flow space can be constructed around the side end wall of the main air pipe when the flexible air bag is being deflated, which avoids the flexible air bag being tightly attached to the outer end wall of the main air pipe during deflation, causing incomplete deflation of the flexible air bag. To some extent, it ensures the stable operation of the internal deflation of the device.

[0029] (9) By installing the air cover in the air port a, and covering the rubber cover on the left side of the air cover, cooperating with the sliding connection of the sliding groove and the clamping frame, the position of the rubber cover can be moved flexibly, which helps to flexibly switch the opening and closing state of the air cover, and to some extent, improves the convenience of the device.

[0030] (10) by the air port b connected with the flexible air bag inside the installation plate is opened on the left end wall, and the cover plate screw connection in the air port b inside, normal air port b is in the cover plate plugging state, can be taken off by rotating the cover plate, so that the air port b is in the open state, through the air pump start-up to the flexible air bag inside continuous inflation, so that the board card main body each circuit element work produced by the heat through the air port b to the outside, help to improve the device when working heat dissipation stability.

[0046] Embodiment 1

[0047] Please refer to Figures 1-10The utility model provides a kind of intelligent substation routing exchange board card with pneumatic protection structure, including side mounting plate 1, the right end wall middle position of side mounting plate 1 is fixedly connected with mutually perpendicular board card main body 101, and the front middle edge position of board card main body 101 is fixedly installed with the plug-in strip 102, multiple connection ports 103 are evenly distributed on the left end wall of side mounting plate 1, the outside of board card main body 101 is fixedly sleeved with the flexible air bag 2 sealedly connected with the left end wall of side mounting plate 1, the plug-in strip 102 is exposed to the outside of flexible air bag 2, and the left end wall of side mounting plate 1 is provided with air hole a203 being communicated with the inside of flexible air bag 2.

[0048] When the device works, the staff can connect the device to the routing switcher inside the intelligent substation, so that the plug-in strip 102 is plugged into the plug-in seat on the routing switcher, then the relevant staff can normally use the equipment, after the use of the device, the staff pulls down the device from the plug-in seat, then the staff can inflate the appropriate amount of gas into the flexible air bag 2 wrapped outside the board card main body 101 through the air hole a203, the flexible air bag 2 is inflated after inflation, and the air hole a203 is plugged after inflation, to form an inflated protective layer outside the board card main body 101, to protect the circuit elements on the board card main body 101, effectively improve the protection performance of the device during storage, reduce the probability of accidental damage of the device during non-use, and the inside of the flexible air bag 2 can be filled with inert gas during inflation, which can further reduce the probability of corrosion and damage of the electronic elements on the board card main body 101 of the device, and the flexible air bag 2 is wrapped outside the board card main body 101 by releasing the gas filled in the inside of the flexible air bag 2 during use, to avoid the influence of the inflated flexible air bag 2 on the normal installation of the device.

[0049] By sleeving the flexible air bag 2 outside the board card main body 101, and opening the air hole a203 communicated with the inside of the flexible air bag 2 on the left end wall of the side mounting plate 1, the inside of the flexible air bag 2 can be inflated and deflated through the air hole a203, and the flexible air bag 2 can be wrapped and protected outside the board card main body 101 by inflation, effectively reducing the probability of damage during storage, and the flexible air bag 2 can be tightly wrapped outside the board card main body 101 by deflation, to avoid the influence of the flexible air bag 2 on the normal installation of the device during use, effectively improving the convenience of the device during use.

[0050] Please refer to Figure 3The end wall of the flexible air bag 2 is internally provided with a hollow structure, the metal shielding layer is uniformly distributed in the hollow structure inside the flexible air bag 2, the micro-control panel 3 is fixedly installed on the left end wall of the side mounting plate 1, and the metal shielding layer is electrically connected with the micro-control panel 3 through wires. When the device is working, the micro-control panel 3 installed on the side mounting plate 1 controls the metal shielding layer arranged in the hollow structure inside the flexible air bag 2 to be electrified. The shielding protection formed by the electrified metal shielding layer shields the external electromagnetic interference. By uniformly arranging the metal shielding layer in the hollow structure inside the flexible air bag 2 and controlling the electrification operation of the metal shielding layer through the micro-control panel 3, the electrified metal shielding layer forms electromagnetic interference shielding protection outside the board card main body 101, which is beneficial to ensure the stability of each electronic element in the board card main body 101 during operation.

[0051] Please refer to Figure 3 The metal shielding layer includes a low-resistance metal layer 201 and a high-permeability metal layer 202 sleeved outside the low-resistance metal layer 201. The low-resistance metal layer 201 is electrically connected with the micro-control panel 3 through wires. When the device is working, when the frequency of the interference electromagnetic field is high, the low-resistance metal layer 201 is electrified to form a counteracting effect on external electromagnetic waves by using the eddy current generated in the metal material with low resistivity, thereby achieving the effect of shielding high-frequency electromagnetic interference from the outside. When the frequency of the interference electromagnetic wave is low, the high-permeability metal layer 202 composed of high-permeability material limits the magnetic lines to the inside of the shielding body to prevent diffusion to the shielded space, effectively realizing the shielding effect of low-frequency electromagnetic interference. By sleeving the low-resistance metal layer 201 and the high-permeability metal layer 202 to form the metal shielding layer, the device can flexibly shield high-frequency electromagnetic interference or low-frequency electromagnetic interference according to the requirements of the working environment, which is beneficial to ensure the comprehensiveness of the electromagnetic interference isolation realized by the metal shielding layer.

[0052] Please refer to Figure 3 The low-resistance metal layer 201 and the high-permeability metal layer 202 are clamped with an insulating diaphragm therebetween, and the low-resistance metal layer 201 and the high-permeability metal layer 202 are internally provided with a grid type structure.

At the same time, by arranging the low-resistance metal layer 201 and the high-permeability metal layer 202 as a grid type structure, the grid type structure can effectively improve the overall structural firmness of the flexible air bag 2, which is beneficial to prolong the service life of the flexible air bag 2 during use.

[0053] Please refer to Figure 2 and Figure 4The air pump 4 is installed on the top of the side mounting plate 1, and the right end wall of the air pump 4 is fixedly installed with air outlet pipes 401 and air inlet pipes 402 arranged symmetrically in front and back. The air outlet pipes 401 are connected with the inside of the flexible air bag 2, and the air inlet pipes 402 are connected with the air port a203. During the operation of the device, the air pump 4 is installed in the space inside the flexible air bag 2 on the top of the side mounting plate 1, and the air inlet pipes 402 of the air pump 4 are connected with the air port a203. The inside of the flexible air bag 2 can be actively filled with gas by the air pump 4 after being started by power supply, without the need for external inflation devices, effectively improving the convenience of the device during use. The start and stop of the air pump 4 can be controlled by the micro control panel 3.

[0059] Please refer to Figure 1 and Figure 4 The inner part of the air port a203 is fixedly embedded with the air cover 5, and the left end of the air cover 5 extends through to the left side of the side mounting plate 1.
