Description

Technical Field

[0001] This invention relates to the field of power monitoring device technology, and specifically to a power system operation monitoring device. Background Technology

[0002] The purpose of power system operation status monitoring is to use effective detection methods and analytical diagnostic techniques to grasp the operating status of equipment in a timely and accurate manner, so as to ensure the safe, reliable and economical operation of equipment. In order to ensure the safe operation of the power system, the monitoring and detection of the operating status of important equipment in the system is carried out. The purpose of monitoring is to detect the development of various deterioration processes of equipment in a timely manner, so as to repair or replace them in time before possible failures or performance degradation that affect normal operation, and avoid accidents that endanger safety.

[0003] Existing power system operation monitoring devices generally suffer from inadequate heat dissipation. A search revealed Chinese patent CN217404345U, which discloses a power system operation monitoring device, including a carrying case. A lid is hinged to the rear of the top of the carrying case. Adjustable boxes are fixedly connected to both sides of the inner cavity of the carrying case, and a placement plate is slidably connected between the two adjustment boxes. The monitoring device housing is placed on top of the placement plate. Mounting plates are fixedly connected to the bottom of both sides of the inner cavity of the monitoring device housing, and a PC board is fixedly connected to the top of the mounting plates. This patent effectively solves the problems of existing power system operation monitoring devices being inconvenient to fix and having inadequate heat dissipation, thus failing to meet usage requirements. However, some shortcomings remain:

[0004] Although this patent improves the heat dissipation capacity of the monitoring device, its fire resistance is generally poor. In the event of a fire due to an accident, the heat dissipation holes on the box make it easier for flames to enter the box through the heat dissipation holes, causing damage to the monitoring device. Summary of the Invention

[0005] The purpose of this invention is to provide a power system operation monitoring device to solve the following technical problem: the existing monitoring devices generally have poor fire resistance. In the event of a fire due to an accident, since the enclosure is equipped with heat dissipation holes, flames can more easily enter the enclosure through the heat dissipation holes, causing damage to the monitoring device.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A power system operation monitoring device includes a housing and a monitoring device body located inside the housing. Placement blocks are symmetrically arranged on both inner walls of the housing. The monitoring device body is located above the placement blocks. Heat dissipation holes are provided on both inner walls of the housing. Baffles are slidably installed on both inner walls of the housing. A first spring is connected to the bottom of each baffle, and one end of the first spring is connected to the bottom wall of the housing. Guide blocks are symmetrically arranged on the bottom wall of the housing. A pull rope is connected to the bottom of one baffle, and one end of the pull rope passes through the bottom wall of the housing and the two guide blocks to connect to the other baffle.

[0008] As a further aspect of the present invention: an opening is provided on one side wall of the box, and a box door is hinged to the opening, and a transparent observation window is provided on the box door.

[0009] As a further aspect of the present invention: a groove is provided on the top of the baffle, a magnet is installed in the groove, and iron rods are provided on both inner walls of the box, with the iron rods located above the heat dissipation holes.

[0010] As a further embodiment of the present invention: a gas box is fixed on the inner surface of the bottom wall of the box body, and piston rods are movably arranged on both sides of the gas box. A second spring is connected between the two opposing piston rods. One end of the piston rod contacts the baffle, and the other end is provided with a vent hole.

[0011] As a further aspect of the present invention: a water tank is installed on the top wall of the box body, a semiconductor cooling chip is installed on the water tank, a cooling pipe is connected to one side wall of the water tank, the cooling pipes are distributed in an S-shape on both side walls of the box body, one end of the cooling pipe is connected to the top wall of the water tank, and one end of the cooling pipe extends into the water tank and is equipped with a water pump.

[0012] As a further aspect of the present invention: a gas collection hood is connected to the top wall of the water tank, one end of the gas collection hood is connected to an exhaust pipe, and a pressure relief valve is installed on the exhaust pipe.

[0013] As a further aspect of the present invention: a sleeve is installed on the bottom wall of the housing via a fixing block. One end of the sleeve is connected to the exhaust pipe. A first piston block is movably disposed inside the sleeve. A movable rod is connected to one side of the first piston block. One end of the movable rod passes through the sleeve and is connected to a blade. A connecting rod is connected to the other side of the first piston block. One end of the connecting rod is connected to a second piston block, and the second piston block is located inside the exhaust pipe. Rubber limiting blocks are symmetrically disposed at the end of the exhaust pipe near the sleeve. A third spring is connected to the first piston block, and one end of the third spring is connected to the inner wall of the sleeve.

[0014] As a further aspect of the present invention: a cutting support block is fixed on the bottom wall of the box, and the pull rope is located between the blade and the cutting support block.

[0015] The beneficial effects of this invention are:

[0016] (1) The present invention sets up a box, and the main body of the monitoring device is located inside the box. The main body of the monitoring device is equipped with a variety of detection modules to monitor the operation status of the power system in real time. During normal use, the heat dissipation holes help the main body of the monitoring device to dissipate heat. At this time, the baffle is located below the heat dissipation holes, and the first spring is in a compressed state. When a fire occurs, the open flame will burn the pull rope, and the first spring will be released to raise the baffle, which will block the heat dissipation holes and prevent the open flame from entering the box, thus protecting the main body of the monitoring device.

[0017] (2) By setting up a gas box, high-pressure flame-retardant gas is added to the gas box in advance. Carbon dioxide gas can be selected. When the baffle is raised, the piston rod moves and the vent is connected to the outside. The flame-retardant gas enters the box. Even if the circuit or other equipment in the box is ignited, it can be extinguished quickly and the loss is reduced.

[0018] (3) By setting up a water tank, a semiconductor cooling chip and a cooling pipe, the present invention utilizes water cooling, which not only effectively reduces the temperature of the box, but also avoids the impact of high external temperatures on the main body of the monitoring device, thus ensuring the normal operation of the equipment.

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual size and shape of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 3 As shown, this invention is a power system operation monitoring device, including a housing 1 and a monitoring device body 2 located inside the housing 1. Placement blocks 4 are symmetrically arranged on both inner walls of the housing 1. The monitoring device body 2 is located above the placement blocks 4. Heat dissipation holes 5 are provided on both inner walls of the housing 1. Baffles 7 are slidably installed on both inner walls of the housing 1. A first spring 6 is connected to the bottom of the baffle 7, and one end of the first spring 6 is connected to the bottom wall of the housing 1. Guide blocks 9 are symmetrically arranged on the bottom wall of the housing 1. A pull rope 8 is connected to the bottom of one baffle 7, and one end of the pull rope 8 passes through the bottom wall of the housing 1 and the two guide blocks 9 to the other baffle 7. A baffle 7 is connected; an opening is provided on one side wall of the enclosure 1, and a door 3 is hinged to the opening, with a transparent observation window on the door 3; the enclosure 1 is installed in a designated position, and the main body 2 of the monitoring device is equipped with various detection modules to monitor the operation status of the power system in real time. During normal use, the heat dissipation hole 5 helps to dissipate heat from the main body 2 of the monitoring device. At this time, 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, the first spring 6 is released, and the baffle 7 rises, blocking the heat dissipation hole 5, preventing the open flame from entering the interior of the enclosure 1, and protecting the main body 2 of the monitoring device.

[0031] See Figure 2 The top of the baffle 7 is provided with a groove, and a magnet 13 is installed in the groove. Iron rods 14 are provided on both sides of the inner wall of the box 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 position of the baffle 7 is fixed by the attraction between the magnet 13 and the iron rods 14.

[0032] See Figure 2 , Figure 3 and Figure 4 A gas chamber 10 is fixed to the inner surface of the bottom wall of the housing 1. Piston rods 11 are movably installed on both sides of the gas chamber 10. A second spring 30 is connected between the two opposing piston rods 11. One end of the piston rod 11 contacts the baffle 7, and the other end has a vent hole 12. In order to further improve the fire resistance, high-pressure flame-retardant gas is added to the gas chamber 10 in advance. When the baffle 7 is raised, under the action of the second spring 30, the piston rods 11 on both sides move away from each other, so that the vent hole 12 is connected to the outside. The high-pressure flame-retardant gas will enter the housing 1 through the vent hole 12. Even if the circuits or equipment in the housing 1 have been ignited, they can be quickly extinguished to reduce losses.

[0033] See Figure 1 and Figure 2 A water tank 15 is installed on the top wall of the enclosure 1, and a semiconductor cooling chip 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 distributed in an S-shape on both sides of the enclosure 1. One end of the cooling pipe 17 is connected to the top wall of the water tank 15, and the other end of the cooling pipe 17 extends into the water tank 15 and is equipped with a water pump. The enclosure 1 is cooled by water, which not only effectively reduces the temperature of the enclosure 1, but also avoids the impact of high external temperatures on the main body 2 of the monitoring device, ensuring the normal operation of the equipment.

[0034] See Figure 1 and Figure 2 A vent 18 is connected to the top wall of the water tank 15. One end of the vent 18 is connected to an exhaust pipe 19, and a pressure relief valve is installed on the exhaust pipe 19. In the event of a fire, the water in the water tank 15 and the cooling pipe 17 will be heated to boiling. In order to avoid excessive pressure and explosion, the water vapor can be discharged through the exhaust pipe 19.

[0035] See 1. Figures 5 to 7A sleeve 21 is installed on the bottom wall of the housing 1 via a fixing block 20. One end of the sleeve 21 is connected to the exhaust pipe 19. A first piston block 25 is movably disposed inside the sleeve 21. A movable rod 22 is connected to one side of the first piston block 25. One end of the movable rod 22 passes through the sleeve 21 and is connected to a blade 23. A connecting rod 27 is connected to the other side of the first piston block 25. One end of the connecting rod 27 is connected to a second piston block 28, which is located inside the exhaust pipe 19. Rubber limit blocks 29 are symmetrically arranged on the end of the exhaust pipe 19 near the sleeve 21. A third spring 26 is connected to the first piston block 25. 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 housing 1. The pull rope 8 is located at... Between the blade 23 and the cutting support block 24; due to the different locations of the open flame, it cannot be guaranteed that the open flame will be below the box 1 when a fire occurs, which may cause the pull rope 8 to not 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 to the left 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 past the rubber limit block 29. At this time, under the action of the third spring 26, the blade 23 is ejected and cuts 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, achieving excellent fire prevention effect.

[0036] The working principle of this invention is as follows: The housing 1 is installed in a designated position. The main body 2 of the monitoring device is equipped with various detection modules to monitor the operation status of the power system in real time. During normal use, the heat dissipation holes 5 help the main body 2 of the monitoring device to ventilate and dissipate heat. At the same time, in conjunction with the water tank 15 and the cooling pipe 17, water cooling is used to effectively reduce the temperature of the housing 1 and prevent the external high temperature from affecting the main body 2 of the monitoring device, thus ensuring the normal operation of the equipment. During normal operation, 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 burns the pull rope 8, and the first spring 6 is released, causing the baffle 7 to rise and block the heat dissipation holes 5, preventing the open flame from entering the housing 1 and protecting the main body 2 of the monitoring device. After the baffle 7 is raised, under the action of the second spring 30, the piston rods 11 on both sides move away from each other, so that the vent 12 is connected to the outside. The high-pressure flame-retardant gas in the gas box 10 enters the housing 1 through the vent 12. Even if the circuits or equipment in the housing 1 have been ignited, the flame can be extinguished quickly to reduce losses.

[0037] Because the location of the open flame varies, it cannot be guaranteed that the open flame will be below the box 1 in the event of a fire. This may prevent the pull rope 8 from being burned off 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 to the left of the rubber limit block 29 (e.g., Figure 7 As shown), 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 past the rubber limit block 29. At this time, under the action of the third spring 26, the blade 23 is ejected and cuts 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, achieving excellent fire prevention effect.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
