[0028] The protective cover 5 is opened by rotating the protective door 6, and the connecting wire 7 is passed through the movable grooves on the first mounting plate 8 and the second mounting plate 9, and then the connecting wire 7 is connected to the first connecting end 3 and the second connecting end 4 respectively. At the same time, the ends of the connecting wire 7 are limited by the movable groove to prevent the connection between the connecting wire 7 and the first connecting end 3 and the second connecting end 4 from being collided or damaged and affecting the stability of the connection. After the installation is completed, the protective door 6 is rotated to close the protective cover 5, thereby further improving the protection of the connecting wire 7 and the first connecting end 3 and the second connecting end 4. When a fire occurs at the connection, smoke is generated. When fog occurs, the smoke alarm 13 is used to sound an alarm, the simulator power supply is cut off, the electromagnetic block 15 loses its magnetism and no longer repels each other, and the two sealing baffles 14 are driven to move closer to each other through the elastic action of the connecting spring 17. When one side of the sealing baffle 14 is in contact with one side of the fixing plate 16, the heat dissipation holes are blocked, so that the inside of the protective cover 5 remains sealed. At the same time, the carbon dioxide gas in the storage box 11 is transported to the inside of the protective cover 5 through the delivery pipe 12 to extinguish the fire at the connection, thereby facilitating the rapid isolation of the connection from the fire source, effectively preventing the spread of the fire, and facilitating use.

[0029] like Figure 1 to Figure 2 As shown, first heat dissipation ports are provided on both sides of the simulator body 1, and two second heat dissipation ports are provided on the rear side of the simulator body 1 and at the bottom of the protective cover 5. The connecting wire 7 passes through the movable groove and extends to the bottom of the first mounting plate 8 and the second mounting plate 9. The fixed structure 10 is located on both sides of the connecting wire 7, and is distributed in a linear array with the center of the first mounting plate 8 and the second mounting plate 9.

[0030] The first heat dissipation port and the second heat dissipation port are used to dissipate heat inside the simulator body 1, thereby improving the use effect of the simulator body 1. The fixing structure 10 is used to limit the connecting wire 7, thereby improving the stability of the connecting wire 7 on the first mounting plate 8 and the second mounting plate 9, thereby reducing the possibility of poor contact caused by loose connection of the connecting wire 7, affecting the effect of the connection between the connecting wire 7 and the simulator, and affecting the use.

[0032] The carbon dioxide gas inside the storage box 11 is transported to the inside of the protective cover 5 through the delivery pipe 12 to extinguish the fire at the connection. The symmetrically arranged sealing baffle 14, fixing plate 16, electromagnetic block 15 and connecting spring 17 facilitate the shielding of the heat dissipation holes on both sides of the protective cover 5. When the simulator body 1 is powered off, the electromagnetic block 15 loses its magnetism, and under the contraction of the connecting spring 17, the bottom of the sealing baffle 14 moves closer to the top of the first mounting plate 8 and the second mounting plate 9, shielding the heat dissipation holes and keeping the protective cover 5 sealed, which is convenient for extinguishing the fire at the connection and reducing the spread of the fire.

One end of the stopper 18 is located in the movable groove, and a connecting rod 19 is fixedly installed on the side of the stopper 18 away from the movable groove. The connecting rod 19 is located inside the movable groove, and one end of the connecting rod 19 is fixedly installed on the inner wall of the movable groove.

[0034] The movable groove on one side of the protective door 6 facilitates the installation of the connecting rod 19 and the block 18. When the protective door 6 closes the protective cover 5, one side of the block 18 moves to one side of the fixed structure 10 to block the movable groove, further improving the sealing of the protective cover 5, facilitating the release of carbon dioxide inside the storage box 11, and improving the fire extinguishing effect.

[0036] When the connecting line 7 is located inside the moving groove and moves, the connecting line 7 is pushed to drive the movable block 100 to move, and the movable block 100 drives the moving rod 103 and the extruding block 104 to move, so that the extruding block 104 squeezes the pushing block 105 away from each other, and the first compression spring is stretched. When the pushing block 105 moves, it drives the first rack 106 to move, so that the gear 107 drives the rotating rod to rotate, and the second rack 108 and the moving block 102 move toward the connecting line 7. The moving block 102 drives the moving plate 101 to move inside the moving groove and fit with the outside of the connecting line 7, and defines the connecting line 7, so that the connecting line 7 is fixed on the first mounting plate 8 and the second mounting plate 9, thereby connecting the connecting line 7 to the first connecting end 3 and the second connecting end 4, thereby improving the stability of the connection. When the connecting line 7 needs to be disassembled or replaced, the connecting line 7 will be The wiring 7 is disassembled from the first connection end 3 and the second connection end 4, and the movable block 100 and the connecting line 7 are moved to the side away from the pushing block 105. The movable block 100 pushes the moving block 102 and the moving plate 101 to move, and the moving plate 101 drives the telescopic rod 109 to extend. At the same time, the movement of the movable block 100 drives the moving rod 103 and the squeezing block 104 to move, and the squeezing block 104 no longer squeezes the pushing block 105. Under the action of the first compression spring, the two pushing blocks 105 drive the first rack 106 to move closer to each other, the gear 107 drives the rotating rod to rotate, and the second rack 108 drives the telescopic rod 109 and the moving plate 101 and the moving block 102 away from the connecting line 7, so that the moving block 102 moves to the inside of the installation groove, and the connecting line 7 is no longer limited, thereby facilitating the replacement of the connecting line 7 and facilitating use.

[0037] like Figures 9 and 10 As shown, an arc groove is provided on the side of the movable block 100 away from the movable rod 103 and on the end of the movable plate 101 away from the movable block 102, the inner wall of the arc groove is in contact with the outer wall of the connecting line 7, both sides of the movable block 100 are slidably connected to the inner wall of the movable groove, the movable plate 101 is located inside the movable groove, and the side of the movable plate 101 away from the movable block 100 is in contact with the side of the stop block 18.

[0038] The arc groove facilitates the fit with the outer wall of the connecting line 7, thereby improving the stability of the limitation of the connecting line 7. When the connecting line 7 fits with the inner wall of the arc groove, the connecting line 7 is pushed to drive the movable block 100 to move along the inner wall of the movable groove, so that the connecting line 7 can be moved to the bottom of the first connecting end 3 and the second connecting end 4 for installation. At the same time, the movement of the extrusion block 104 is driven by the moving rod 103, so that the pushing block 105 drives the first rack 106 to move, so that the gear 107 rotates, and the second rack 108 drives the telescopic rod 109 and the moving plate 101 to move, so that the moving block 102 can move into the moving groove, and the moving groove is blocked together with the block 18, so as to facilitate the sealing of the bottom of the protective cover 5.

[0039] like Figures 9 and 10As shown, one side of the moving block 102 and the pushing block 105 are slidably connected to the inner wall of the installation groove, the first compression spring is located on both sides of the extrusion block 104, and both sides of the extrusion block 104 are in contact with one side of the pushing block 105, and the rotating rod is rotatably connected to the inner wall of the installation groove. The pushing block 105, the first rack 106, the gear 107, the second rack 108, the telescopic rod 109, the moving plate 101 and the moving block 102 are all symmetrically arranged with the movable block 100 as the center.

[0040] When the movable rod drives the moving rod 103 to move, the moving rod 103 pushes the extrusion block 104 to move along the inner wall of the installation groove and squeezes the pushing block 105, so that the pushing blocks 105 move away from each other along the inner wall of the installation groove. When the two sides of the extrusion block 104 are in contact with the pushing block 105 close to the side of the first spring, the pushing block 105 drives the first rack 106 to move, and the gear 107 drives the rotating rod to rotate along the inner wall of the installation groove to improve the stability of the rotation of the gear 107. The second rack 108 drives the moving plate 101 to move into the moving groove and limit the connecting line 7. Through the symmetrically arranged first rack 106, gear 107, second rack 108, telescopic rod 109, moving plate 101 and moving block 102, it is convenient to limit the connecting line 7 from both sides of the moving plate 101, further improving the stability of the connecting line 7 and preventing the connecting line 7 from loosening and affecting its use.

[0041] like Figures 9 and 10 As shown, the first rack 106 and the second rack 108 are slidably connected to the inner wall of the mounting groove, the second compression spring 20 is fixedly installed on one end of the first rack 106 away from the gear 107, a fixed block is provided between two adjacent movable plates 101, the fixed block is fixedly installed on the inner wall of the mounting groove, one end of the second compression spring 20 is fixedly installed on the inner wall of the mounting groove, and the other end thereof is fixedly installed on one side of the fixed block.

[0042] When the first rack 106 moves along the inner wall of the installation groove, the second compression spring 20 is compressed, so that the gear 107 drives the rotating rod to rotate, and the second rack 108 drives the moving plate 101 and the moving block 102 to move, and the fixing block is used to facilitate the connection between one end of the connecting spring 17 and the second rack 108. The first rack 106 is pressed tightly by the second compression spring 20, thereby improving the limiting effect of the moving block 102 on the connecting line 7, preventing the connection between the connecting line 7 and the first connection end 3 and the second connection end 4 from being collided or damaged, affecting the stability of the connection, thereby causing poor contact between the connecting line 7 and the simulator body 1, and loose joint contacts are prone to cause DC arcing, further reducing the possibility of fire.

[0043] Working principle: When in use, the protective cover 5 is opened by rotating the protective door 6, and the rotating door drives the moving rod 103 and the stopper 18 to separate from the moving groove, and then the connecting line 7 passes through the moving grooves on the first mounting plate 8 and the second mounting plate 9, so that one side of the connecting line 7 fits with the arc groove of the movable block 100, and the connecting line 7 is pushed to drive the movable block 100 to move, and the movable block 100 drives the moving rod 103 and the extrusion block 104 to move along the inner wall of the mounting groove, so that the extrusion block 104 squeezes the pushing block 105 away from each other, and makes the first A compression spring is stretched, and when the push block 105 moves, it drives the first rack 106 to move, so that the gear 107 drives the rotating rod to rotate, and the second rack 108 moves the moving block 102 to the connecting line 7. The moving block 102 drives the moving plate 101 to move to the inside of the moving groove and fits with the outside of the connecting line 7, so as to limit the connecting line 7, so that the connecting line 7 is fixed on the first mounting plate 8 and the second mounting plate 9, so as to connect the connecting line 7 with the first connecting end 3 and the second connecting end 4, and connect the connecting line 7 with the second connecting end 4 respectively. A connecting end 3 is connected to a second connecting end 4, and at the same time, the end of the connecting line 7 is limited by a movable plate 101 to prevent the connecting line 7 from being collided or damaged at the connection between the first connecting end 3 and the second connecting end 4, affecting the stability of the connection. After the installation is completed, the protective door 6 is rotated to close the protective cover 5, and the block 18 is moved to the movable groove and fits with one side of the movable plate 101, so that the bottom of the first mounting plate 8 and the second mounting plate 9 remain sealed. When a fire occurs at the connection and smoke is generated, an alarm is sounded through the smoke alarm 13, the simulator power is cut off, the electromagnetic block 15 loses its magnetism and no longer repels each other. The two sealing baffles 14 are driven to move closer to each other through the elastic action of the connecting spring 17. When one side of the sealing baffle 14 fits with one side of the fixed plate 16, the heat dissipation hole is blocked, so that the inside of the protective cover 5 remains sealed. At the same time, the carbon dioxide gas inside the storage box 11 is transported to the inside of the protective cover 5 by the delivery pipe 12, and the fire is extinguished at the connection, so that the connection can be quickly isolated from the fire source, effectively preventing the spread of the fire, and facilitating use.

[0044] When it is necessary to disassemble or replace the connecting wire 7, the connecting wire 7 and the first connecting end 3 and the second connecting end 4 are disassembled, and the movable block 100 and the connecting wire 7 are moved to the side away from the pushing block 105. The movable block 100 pushes the moving block 102 and the moving plate 101 to move, and the moving plate 101 drives the telescopic rod 109 to extend. At the same time, the movement of the movable block 100 drives the moving rod 103 and the squeezing block 104 to move, and the squeezing block 104 no longer squeezes the pushing block 105. Under the action of the first compression spring, the two pushing blocks 105 drive the first rack 106 to move closer to each other, the gear 107 drives the rotating rod to rotate, and the second rack 108 drives the telescopic rod 109 and the moving plate 101 and the moving block 102 away from the connecting wire 7, so that the moving block 102 moves to the inside of the installation groove, and the connecting wire 7 is no longer restricted, thereby facilitating the replacement of the connecting wire 7 and facilitating use.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
