[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 3 As shown, the present invention is a power system operation monitoring device, comprising a box body 1 and a monitoring device body 2 located in the box body 1, placement blocks 4 are symmetrically arranged on the inner walls on both sides of the box body 1, the monitoring device body 2 is located above the placement blocks 4, heat dissipation holes 5 are arranged on the inner walls on both sides of the box body 1, baffles 7 are slidably installed on the inner walls on both sides of the box body 1, the bottom of the baffle 7 is connected to a first spring 6, one end of the first spring 6 is connected to the bottom wall of the box body 1, and guide blocks 9 are symmetrically arranged on the bottom wall of the box body 1, one of the baffles 7 is connected to a pull rope 8 at the bottom, one end of the pull rope 8 passes through the bottom wall of the box body 1 and the two guide blocks 9 and the other A baffle 7 is connected; an opening is provided on one side wall of the box body 1, and a box door 3 is hinged at the opening, and a transparent observation window is provided on the box door 3; the box body 1 is installed at a specified position, and a variety of detection modules are provided in the monitoring device body 2 to monitor the operating status of the power system in real time. During normal use, the heat dissipation holes 5 help to dissipate heat of the monitoring device body 2. At this time, the baffle 7 is located below the heat dissipation holes 5, and the first spring 6 is in a compressed state. When a fire occurs, the open flame will burn the pull rope 8, and the first spring 6 will be released to raise the baffle 7, thereby blocking the heat dissipation holes 5, preventing the open flame from entering the box body 1, and protecting the monitoring device body 2.

[0034] See also Figure 2 A groove is provided on the top of the baffle 7, in which a magnet 13 is installed. Iron rods 14 are provided on the inner walls on both sides of the box body 1, and the iron rods 14 are located above the heat dissipation holes 5; in order to ensure the stability of the baffle 7 after it is raised, the magnet 13 is adsorbed with the iron rods 14 to fix the position of the baffle 7.

[0035] See also Figure 2 , Figure 3 and Figure 4 A gas box 10 is fixed to the inner surface of the bottom wall of the box body 1, and piston rods 11 are movably arranged on both side walls of the gas box 10. A second spring 30 is connected between the two opposite piston rods 11. One end of the piston rod 11 is in contact with the baffle 7, and the other end is provided with an air vent 12. In order to further improve the fireproof performance, high-pressure flame-retardant gas is added to the gas box 10 in advance. When the baffle 7 is raised, under the action of the second spring 30, the piston rods 11 on both sides are separated from each other, so that the air vent 12 is connected to the outside world. The high-pressure flame-retardant gas enters the box body 1 through the air vent 12. Even if the lines or equipment in the box body 1 have been ignited, they can be quickly extinguished to reduce losses.

[0036] See also Figure 1 and Figure 2 A water tank 15 is installed on the top wall of the box body 1, and a semiconductor refrigeration plate 16 is installed on the water tank 15. A cooling pipe 17 is connected to one side wall of the water tank 15. The cooling pipe 17 is S-shaped and distributed on both side walls of the box body 1. One end of the cooling pipe 17 is connected to the top wall of the water tank 15, and one end of the cooling pipe 17 extends into the water tank 15 and is installed with a water pump; the box body 1 is cooled by water cooling, which not only effectively reduces the temperature of the box body 1, but also avoids the influence of external high temperature on the monitoring device body 2, thereby ensuring the normal operation of the equipment.

[0037] See also Figure 1 and Figure 2 An air collecting hood 18 is connected to the top wall of the water tank 15, one end of the air collecting hood 18 is connected to an exhaust pipe 19, and a pressure relief valve is installed on the exhaust pipe 19; when a fire occurs, the water in the water tank 15 and the cooling pipe 17 will be heated to boil, and in order to avoid explosion caused by excessive pressure, the water vapor can be discharged through the exhaust pipe 19.

[0038] See 1. Figures 5 to 7A sleeve 21 is installed on the bottom wall of the box body 1 through a fixed block 20, one end of the sleeve 21 is connected to the exhaust pipe 19, a first piston block 25 is movably arranged in the sleeve 21, one side of the first piston block 25 is connected to a movable rod 22, one end of the movable rod 22 passes through the sleeve 21 and is connected to a blade 23, the other side of the first piston block 25 is connected to a connecting rod 27, one end of the connecting rod 27 is connected to a second piston block 28, and the second piston block 28 is located in the exhaust pipe 19, and a rubber limit block 29 is symmetrically arranged at one end of the exhaust pipe 19 close to the sleeve 21, and a third spring 26 is connected to the first piston block 25, and one end of the third spring 26 is connected to the inner wall of the sleeve 21; a cutting support block 24 is fixed on the bottom wall of the box body 1, and the pull rope 8 is located between the blade 23 and the cutting support block 24; due to the different positions where the open flame is generated, it cannot be guaranteed that the open flame is below the box body 1 when a fire occurs, which may cause the pull rope 8 to fail to be burned off in time. Therefore, when the aqueous solution in the water tank 15 and the cooling pipe 17 is heated and evaporated, it is discharged through the exhaust pipe 19. Initially, the second piston block 28 is located on the left side of the rubber limit block 29, and the third spring 26 is in a stretched state. As the water vapor increases, the air pressure in the exhaust pipe 19 increases, pushing the second piston block 28 over the rubber limit block 29. At this time, under the action of the third spring 26, the blade 23 is ejected to cut off the pull rope 8. In other words, as long as a fire occurs, no matter where the open flame is, the baffle 7 can be effectively raised, thereby achieving an excellent fire prevention effect.

[0039] The working principle of the present invention is as follows: the box 1 is installed at a designated position, and a plurality of detection modules are arranged in the monitoring device body 2 to monitor the operation status of the power system in real time. During normal use, the heat dissipation holes 5 are helpful for ventilation and heat dissipation of the monitoring device body 2. At the same time, in conjunction with the water tank 15 and the cooling pipe 17, the water cooling method is used to effectively reduce the temperature of the box 1, and also to avoid the influence of the external high temperature on the monitoring device body 2, thereby ensuring the normal operation of the equipment. During normal operation, the baffle 7 is located below the heat dissipation hole 5, and the first spring 6 is in a compressed state. When a fire occurs, the open flame burns the pull rope 8, and the first spring 6 is released to raise the baffle 7, thereby blocking the heat dissipation hole 5, so that the open flame cannot enter the box 1, thereby protecting the monitoring device body 2. After the baffle 7 is raised, under the action of the second spring 30, the piston rods 11 on both sides are separated from each other, so that the air vent 12 is connected to the outside world, and the high-pressure flame-retardant gas in the gas box 10 enters the box 1 through the air vent 12. Even if the line or equipment in the box 1 has been ignited, the flame can be quickly extinguished to reduce losses.

[0040] Due to the different positions of the open flame, it is impossible to ensure that the open flame is below the box body 1 when a fire occurs, which may cause the pull rope 8 to fail to burn out in time. Therefore, when the aqueous solution in the water tank 15 and the cooling pipe 17 evaporates due to heat, it will be discharged through the exhaust pipe 19. Initially, the second piston block 28 is located on the left side of the rubber limit block 29 (such as Figure 7 As shown in the figure, the third spring 26 is in a stretched state. As the amount of water vapor increases, the air pressure in the exhaust pipe 19 increases, pushing the second piston block 28 over the rubber limit block 29. At this time, under the action of the third spring 26, the blade 23 is ejected to cut off the pull rope 8. In other words, as long as a fire occurs, no matter where the open flame is, the baffle 7 can be effectively raised, thereby achieving an excellent fire prevention effect.

[0041] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
