DETAILED DESCRIPTION

[0024] The technical solution of this application will be described below with reference to embodiments.

[0025] The present application provides a new energy station network security monitoring and early warning system, as shown in Figures 1-5, including a box body 1, a fixed base 11' is fixedly connected to the bottom inner wall of the box body 1, a device body 2 is fixedly installed on the top of the fixed base, a cooling device 3 is fixedly connected to the top of the box body 1, purification boxes 31' are provided on both sides of the cooling device 3, a controller 4 is fixedly installed on the front side of the box body 1, and an alarm light 5 is provided on one side of the controller 4.

[0026] A warning light 6 is provided on the front side of the box body 1, and an installation box 7 is fixedly connected to the inner wall of the top of the box body 1. The inner wall of the installation box 7 is fixedly connected to a first telescopic rod 8, one end of the first telescopic rod 8 is fixedly connected to a movable plate 9, one side of the movable plate 9 is fixedly connected to a first electromagnetic block 10, a conductive block 11 is provided on one side of the first electromagnetic block 10, and one side of the conductive block 11 is fixedly connected to a connecting plate 111.

[0027] One side of the connecting plate 111 is fixedly connected to the first metal block 12, the other side of the conductive block 11 is electrically connected to the alarm light 5, the right side of the conductive block 11 is electrically connected to the second electromagnetic block 13, the bottom of the second electromagnetic block 13 is provided with a support frame 131, the top of the support frame 131 is fixedly installed with a fixed box 14, one side of the second electromagnetic block 13 is provided with a second metal block 15, one side of the second metal block 15 is fixedly connected to the connecting frame 16, the right side of the connecting frame 16 is fixedly connected to the second telescopic rod 17, the bottom of the connecting frame 16 and the outer surface of one side of the fixed box 14 are fixedly connected to a fixing plate 141.

[0028] The top of the fixed plate 141 is fixedly connected to a fixed tube 18, and the interior of the fixed tube 18 is movably connected to a push plate 19, one end of the push plate 19 is fixedly connected to the connecting frame 16, and the end of the fixed tube 18 close to the installation box 7 is fixedly connected to a connecting tube 20, one end of the connecting tube 20 is fixedly connected to an airbag 21, one side of the airbag 21 is fixedly connected to a socket 22, and one side of the socket 22 is provided with a slot 221, and the rear side of the warning light 6 is fixedly connected to an insertion rod 23, and the insertion rod 23 is plugged into the slot 221.

[0029] When the temperature inside the box 1 needs to be lowered, the first electromagnetic block 10 is energized through the controller 4, so that the first telescopic rod 8 is extended, and the movable plate 9 drives the first electromagnetic block 10 to attract the first metal block 12, so that the conductive block 11 is energized, and the alarm light 5 flashes. Since the conductive block 11 is electrically connected to the second electromagnetic block 13, when the conductive block 11 is energized, the second electromagnetic block 13 generates a magnetic force to attract the second metal block 15, so that the second telescopic rod 17 is extended, and the connecting frame 16 moves to drive the second metal block 15 to attract the second electromagnetic block 13. When the connecting frame 16 moves, it squeezes the push plate 19, so that the push plate 19 is fixed on the tube 1. 8 moves inside, squeezing the air inside the fixed tube 18 into the inside of the airbag 21 through the connecting tube 20. The airbag 21 inflates and pushes the socket 22 to move in the direction of the insertion rod 23. When the socket 22 is plugged into the insertion rod 23, the prompt light 6 lights up and the alarm light 5 flashes normally. The equipment main body 2 is cooled by the cooling device 3, so as to remind the staff to adjust the equipment main body 2. When the alarm light 5 flashes, the prompt light 6 does not light up. At this time, the alarm light 5 fails, thereby reminding the staff to check the equipment main body 2 and the alarm light 5, so that the alarm light 5 can be repaired, which is beneficial to the use of the equipment main body 2.

[0030] As shown in Figure 2-3, the installation box 7 is located on the top of the equipment body 2, one end of the alarm light 5 and the prompt light 6 are located outside the box body 1, and the other end extends through the box body 1 to the inside of the installation box 7, the conductive block 11 is fixedly connected to the bottom inner wall of the installation box 7, and the movable plate 9 and the connecting plate 111 are arranged opposite to each other.

[0031] The installation box 7 facilitates fixing the alarm light 5 and the prompt light 6, and the conductive block 11 facilitates making the alarm light 5 flash when powered on. The relatively arranged connecting plate 111 and the movable plate 9 facilitate the first metal block 12 on the movable plate 9 and the first electromagnetic block 10 on the connecting plate 111 to attract each other when the first electromagnetic block 10 is powered on. The coordinated use of the alarm light 5 and the prompt light 6 facilitates observing whether the alarm light 5 has a fault to prevent affecting the use of the device main body 2.

[0032] As shown in Figure 3-4, the bottom of the support frame 131 is fixedly connected to the inner wall of the installation box 7. The support frame 131 is located at the bottom of the second electromagnetic block 13 and the second metal block 15. The second metal block 15 is located at the top of the installation box 7. A groove 71 is provided on the inner wall of the installation box 7. The second telescopic rod 17 is fixedly connected to the inner wall of the groove 71. The second telescopic rod 17 and the connecting frame 16 are located on the right side of the fixed box 14.

[0033] The support frame 131 facilitates fixing the installation box 7, and the groove 71 facilitates fixing the second telescopic rod 17. When the second electromagnetic block 13 is energized to generate magnetic force, the second telescopic rod 17 extends, thereby facilitating the adsorption of the second electromagnetic block 13 and the second metal block 15.

[0034] As shown in Figure 4-5, the connecting frame 16 is L-shaped, and the vertical end of the connecting frame 16 is fixedly connected to a slider 161. A slide groove 142 is provided on the top of the fixed plate 141. The slider 161 is slidably connected to the slide groove 142. The connecting tube 20 passes through the fixed box 14 and extends to the interior of the fixed box 14. The airbag 21 is fixedly installed inside the installation box 7, and the airbag 21 is located on the rear side of the socket 22.

[0035] Since the connecting frame 16 is L-shaped, when the second metal block 15 drives the connecting frame 16 to move, it is convenient for the slider 161 to move in the slide groove 142 at the top of the fixed plate 141, so that the connecting frame 16 drives the pushing plate 19 to move toward the inside of the fixed tube 18, so that the air in the fixed tube 18 is transported to the inside of the airbag 21 through the connecting tube 20, causing the airbag 21 to swell and push the socket 22 to move.

[0036] As shown in Figures 5-6, strip blocks 24 are fixedly connected to both sides of the socket 22, and a plurality of equally distributed balls 25 are fixedly connected to the bottom of the strip block 24. A first fixed block 26 is fixedly connected to both sides of the inner wall of the installation box 7. A movable groove 261 is provided on the top of the first fixed block 26. The strip block 24 is located on the top of the first fixed block 26. The balls 25 are slidably connected to the movable groove 261. A limiting groove 222 is provided on one side of the slot 221 and is located inside the socket 22. A limiting device is provided inside the limiting groove 222.

[0037] When the socket 22 moves, the ball 25 at the bottom of the bar block 24 moves in the moving groove 261 inside the first fixed block 26, reducing friction, thereby facilitating the rapid movement of the socket 22 and the insertion of the rod 23. The limiting device facilitates the improvement of the insertion stability of the rod 23 and the socket 22, preventing poor contact between the rod 23 and the socket 22, which may cause a malfunction of the warning light 6.

[0038] As shown in Figures 5-7, the limiting device includes a fixed rod 223, a fixed groove 224 is provided on the socket 22, the upper and lower ends of the fixed rod 223 are rotatably connected to the inner wall of the fixed groove 224, and the middle part of the fixed rod 223 is fixedly connected to a gear 27, and a movable plate 28 is provided on one side of the gear 27. The movable plate 28 is provided with a first tooth groove 281 on the side close to the gear 27, and the first tooth groove 281 is engaged with the gear 27. One end of the movable plate 28 is fixedly connected to a compression spring 29, and the other end thereof is fixedly connected to a limiting block 30. The movable plate 28 is located inside the fixed groove 224, and one end of the compression spring 29 is fixedly connected to the inner wall of the fixed groove 224. The movable plate 28 and the gear 27 are symmetrically arranged around the center of the socket 22.

[0039] When the socket 22 is plugged into the plug rod 23, the plug rod 23 moves to the inside of the slot 221, and the second tooth grooves 231 on both sides of the plug rod 23 engage with the gear 27, causing the gear 27 to rotate. Since the first tooth groove 281 on one side of the movable plate 28 engages with the gear 27, when the gear 27 rotates, the compression spring 29 extends, pushing the movable plate 28 to move toward the outside of the socket 22. When the movable plate 28 moves to the outside of the socket 22 and the limit block 30 is plugged into the limiting groove 311, the plug rod 23 is connected and fixed to the socket 22, thereby lighting up the warning light 6, making the connection between the plug rod 23 and the socket 22 more stable, which is convenient for preventing the warning light 6 from malfunctioning.

[0040] As shown in Figure 7, both sides of the insertion rod 23 are fixedly connected with a second fixed block 31, one side of the second fixed block 31 is provided with a limiting groove 311, the limit block 30 is plugged into the limiting groove 311, and both sides of the insertion rod 23 are provided with a second tooth groove 231, which is engaged with the gear 27.

[0041] The second tooth grooves 231 on both sides of the insertion rod 23 facilitate engagement with the gear 27 when the insertion rod 23 moves into the slot 221, and causes the gear 27 to rotate, and is plugged into the limiting groove 311 through the limit block 30, thereby facilitating the fixation of the insertion rod 23 and the socket 22, thereby improving stability.

[0042] Working principle: When in use, when the cooling device 3 can transmit the temperature information inside the box 1 to the controller 4, when the temperature inside the box 1 is high, the controller 4 enables the first electromagnetic block 10 to generate magnetic force to adsorb to the first metal block 12, and at the same time makes the first telescopic rod 8 extend, and the movable plate 9 drives the first electromagnetic block 10 to attract the first metal block 12, so that the conductive block 11 is energized, and the conductive block 11 makes the alarm light 5 flash. Since the conductive block 11 is electrically connected to the second electromagnetic block 13, when the conductive block 11 is energized, the second electromagnetic block 13 generates magnetic force to adsorb the second metal block 15, so that the second telescopic rod 17 extends, and the connecting frame 16 moves toward the direction of the second electromagnetic block 13, driving the second metal block 15 and the second electromagnetic block 13 The air in the fixed tube 18 is squeezed into the airbag 21 through the connecting tube 20, and the airbag 21 is inflated and pushes the socket 22 to move. The balls 25 at the bottom of the bar blocks 24 on both sides of the socket 22 move in the movable groove 261 inside the first fixed block 26, so that the socket 22 moves toward the insertion rod 23. When the socket 22 is connected to the insertion rod 23, the prompt light 6 lights up and the alarm light 5 flashes normally, so as to remind the staff to cool down the equipment body 2. When the alarm light 5 flashes, the prompt light 6 is not on. At this time, the alarm light 5 has a fault, thereby reminding the staff to repair the alarm light 5.

[0043] When the insertion rod 23 moves to the inside of the slot 221, the second tooth grooves 231 on both sides of the insertion rod 23 engage with the gear 27, causing the gear 27 to rotate. Since the first tooth groove 281 on one side of the movable plate 28 engages with the gear 27, when the gear 27 rotates, it pushes the movable plate 28 to move to the outside of the socket 22, and the compression spring 29 extends. When the movable plate 28 moves to the external limit block 30 of the socket 22 and engages with the limiting groove 231, the insertion rod 23 is connected and fixed to the socket 22, thereby connecting and fixing the insertion rod 23 to the socket 22, and the warning light 6 lights up, making the connection between the insertion rod 23 and the socket 22 more stable, preventing poor contact between the insertion rod 23 and the socket 22, which causes a failure of the warning light 6.

[0044] Through the coordinated use of the alarm light, prompt light, first telescopic rod, first electromagnetic block, second metal block, conductive block, second electromagnetic block, first metal block, connecting frame, second telescopic rod, fixed tube, push plate, connecting tube, airbag, socket and plug rod, the first electromagnetic block and the second metal block are energized through the controller, so that the alarm light flashes when the conductive block is energized, and at the same time, the conductive block energizes the second electromagnetic block and attracts the first metal block, so that the second telescopic rod extends, and the connecting frame drives the push plate to squeeze the air inside the fixed tube into the airbag through the connecting tube, so that the airbag bulges and pushes the socket and the plug rod to plug, so that the prompt light lights up. When the alarm light flashes and the prompt light does not light up, the alarm light is faulty, which makes it easy to detect whether the alarm light is faulty, easy to repair the alarm light, and easy to use the main body of the equipment.

[0045] Through the coordinated use of the socket, the insertion rod, the gear, the first tooth groove, the second tooth groove, the movable plate, the compression spring, the limit block and the limiting groove, the insertion rod is inserted into the interior of the slot, and the second tooth grooves on both sides of the insertion rod engage with the gear, causing the gear to rotate. Since the first tooth groove on one side of the movable plate engages with the gear, when the gear rotates, the movable plate moves toward the outside of the socket, and the compression spring extends, causing the limit block to engage with the limiting groove, thereby fixing the insertion rod inside the socket, causing the warning light to light up, thereby improving the connection stability between the insertion rod and the socket, and preventing poor contact between the insertion rod and the socket, which may cause a warning light failure.

[0046] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them.
