Description

Technical Field

[0001] This utility model relates to the field of monitoring devices, and in particular to an electrical equipment condition monitoring device. Background Technology

[0002] An electrical equipment condition monitoring device is an intelligent device used to monitor the operating status of electrical equipment in real time, collect key parameters, and evaluate the health status of the equipment through data analysis. Its core objective is to detect potential equipment failures in advance, avoid sudden downtime or safety accidents, and improve equipment reliability and operation and maintenance efficiency.

[0003] Traditional electrical equipment condition monitoring devices mostly rely on natural ventilation for heat dissipation, lacking an active heat dissipation mechanism, which is inefficient and may affect the normal operation and service life of the equipment. In addition, most of them do not have pressure relief devices. Faults inside electrical equipment may cause gas decomposition and temperature rise, which in turn increases the internal pressure. If the pressure is not relieved in time, it may damage the equipment casing or even cause more serious accidents such as explosions.

[0004] Therefore, those skilled in the art have provided an electrical equipment condition monitoring device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrical equipment condition monitoring device. This device effectively absorbs the heat generated by the electrical equipment inside the protective enclosure during operation by setting up a coolant circulation system and using a protective enclosure made of thermally conductive material. When the temperature sensor detects that the internal temperature of the outer enclosure exceeds a predetermined value, the control panel automatically starts the servo motor, driving the cooling fan to operate. The air blown out by the cooling fan passes through the coolant pipe, forming a cooler air that is directly blown onto the protective enclosure, thereby reducing the overall temperature and ensuring that the equipment operates within a safe temperature range, extending the equipment's lifespan and improving operational stability. A pressure relief channel is set inside the protective enclosure. When the electrical equipment malfunctions, it may cause gas decomposition and temperature rise, which in turn increases the internal pressure. The pressure relief channel extends through the outer enclosure to the outside of the device, releasing the excess pressure to protect the equipment and the surrounding environment, preventing serious accidents caused by internal explosions or excessive pressure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An electrical equipment condition monitoring device includes an outer casing, a through pipe, a first connecting pipe, and a second connecting pipe. A protective box is fixedly connected to the center of the bottom surface of the outer casing. Columns are fixedly connected to the front and rear of the inner wall of the outer casing. Cooling fans are rotatably connected to the upper and lower parts of the columns on the inner wall of the outer casing, away from the protective box. Servo motors are fixedly connected to the upper parts of the front and rear ends of the inner wall of the outer casing. Coolant pipes are fixedly connected to the front and rear ends of the inner wall of the outer casing near the protective box. The front end of the top of the outer casing is fixedly connected to… The device includes a coolant tank, a circulating pump fixedly connected to the rear end of the top surface of the outer casing, a temperature sensor fixedly connected to the middle of the top surface of the inner casing, a pressure sensor fixedly connected to the middle of the top surface of the inner casing, a pressure relief channel fixedly connected to the middle of the rear end of the other side of the outer wall of the protective casing, a metal wire mesh fixedly connected to one side of the inner wall of the pressure relief channel, a pressure relief valve fixedly connected to the other side of the outer wall of the pressure relief channel, multiple heat dissipation holes opened at both the front and rear ends of the outer casing, and a control panel fixedly connected to the upper part of the rear end of the outer casing.

[0008] Through the above technical solution, the electrical equipment condition monitoring device effectively absorbs the heat generated by the electrical equipment inside the protective box during operation by setting up a coolant circulation system and using a protective box made of thermally conductive materials. When the temperature sensor detects that the internal temperature of the outer box exceeds a predetermined value, the control panel automatically starts the servo motor to drive the cooling fan. The air blown out by the cooling fan passes through the coolant pipe, forming a cooler air that blows directly onto the protective box, thereby reducing the overall temperature and ensuring that the equipment operates within a safe temperature range, extending the equipment's lifespan and improving operational stability. A pressure relief channel is set up inside the protective box. When the electrical equipment malfunctions, it may cause gas decomposition and temperature rise, which in turn increases the internal pressure. The pressure relief channel extends through the outer box to the outside of the device, releasing the excess pressure to protect the safety of the equipment and the surrounding environment and prevent serious accidents caused by internal explosions or excessive pressure.

[0009] Furthermore, each of the cooling fans is fixedly connected to a drive wheel at the end away from the column, and the upper drive wheel is fixedly connected to the output end of the servo motor. Each drive wheel is fitted with a belt on its outer wall.

[0010] The above technical solution enables a single servo motor to drive multiple cooling fans simultaneously, simplifying the power system structure, reducing the number of motors used, and lowering equipment costs and energy consumption.

[0011] Furthermore, the outlet of the coolant tank and the inlet of the circulating pump are connected by a connecting pipe;

[0012] The above technical solution connects the coolant tank and the circulation pump through a pipe, ensuring that the coolant can flow smoothly from the coolant tank to the circulation pump, thus achieving efficient coolant circulation.

[0013] Furthermore, the lower end of one side of the front-end coolant pipe and the rear-end coolant pipe are connected through a No. 1 connecting pipe.

[0014] Through the above technical solution, the No. 1 connecting pipe connects the front and rear coolant pipes, creating a smoother circulation loop. Driven by the circulation pump, the coolant starts from the coolant tank, passes through the circulation pump, the rear coolant pipe, the No. 1 connecting pipe, and the front coolant pipe, and finally flows back to the coolant tank, forming a closed loop.

[0015] Furthermore, the lower end of the other side of the front-end coolant pipe is connected to the coolant tank through the No. 2 connecting pipe, and the lower end of the other side of the rear-end coolant pipe is connected to the circulation pump through the No. 2 connecting pipe.

[0016] Through the above technical solution, the coolant flows out of the coolant tank, is pressurized by the circulation pump, and then enters the front coolant pipe. After absorbing heat from inside the protective tank, it flows back to the coolant tank through the second connecting pipe. Simultaneously, the coolant in the rear coolant pipe, after absorbing heat, returns to the circulation pump through the second connecting pipe and re-enters the circulation system. This design ensures continuous coolant flow throughout the system, effectively removing the heat generated during equipment operation.

[0017] Furthermore, the outer wall of the pressure relief channel penetrates the middle of the lower end of the other side of the outer casing;

[0018] With the above technical solution, the pressure relief channel is set in the middle of the lower end of the other side of the outer casing. When the gas inside the protection box decomposes and the temperature rises due to electrical equipment failure, which in turn causes the internal gas pressure to increase abnormally, the pressure relief channel at the lower end can quickly discharge the high-pressure gas.

[0019] Furthermore, the protective box is made of a heat-conducting plate;

[0020] Through the above technical solutions, the protective box made of heat-conducting plate material can quickly absorb and conduct the heat generated by the internal electrical equipment during operation, thereby improving heat dissipation efficiency.

[0021] Furthermore, an outer door is rotatably connected to both the front and rear ends of one side of the outer wall of the outer casing, and an inner door is rotatably connected to the front end of one side of the outer wall of the protective box.

[0022] The above technical solutions provide convenient maintenance and operation interfaces, which improve the operability, sealing, and safety of the equipment, and facilitate its installation and commissioning by making maintenance and repair easier.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes an electrical equipment condition monitoring device. This device effectively absorbs the heat generated by the electrical equipment inside the protective box during operation by setting up a coolant circulation system and using a protective box made of thermally conductive material. When the temperature sensor detects that the internal temperature of the outer box exceeds a predetermined value, the control panel automatically starts the servo motor to drive the cooling fan to run. The air blown out by the cooling fan passes through the coolant pipe to form a cooler air, which is directly blown onto the protective box, thereby reducing the overall temperature, ensuring that the equipment operates within a safe temperature range, extending the equipment life and improving operational stability.

[0025] 2. The present invention proposes an electrical equipment condition monitoring device, which has a pressure relief channel set inside the protection box. When the electrical equipment malfunctions, it may cause gas decomposition and temperature rise, which in turn increases the internal gas pressure. The pressure relief channel extends through the outer box to the outside of the device to release the excess pressure, thereby protecting the safety of the equipment and the surrounding environment and preventing serious accidents caused by internal explosion or excessive pressure.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] An electrical equipment condition monitoring device includes an outer casing 1, a through pipe 10, a first connecting pipe 11, and a second connecting pipe 14. A protective box 2 is fixedly connected to the center of the bottom surface of the outer casing 1. Columns 3 are fixedly connected to the front and rear of the inner wall of the outer casing 1. Cooling fans 5 are rotatably connected to the upper and lower parts of the columns 3 on the inner wall of the outer casing 1 away from the protective box 2. Servo motors 6 are fixedly connected to the upper parts of the front and rear ends of the inner wall of the outer casing 1. Coolant is fixedly connected to the front and rear ends of the inner wall of the outer casing 1 near the protective box 2. Pipe 7, a coolant tank 8 is fixedly connected to the front end of the outer top surface of the outer casing 1, a circulation pump 9 is fixedly connected to the rear end of the outer top surface of the outer casing 1, a temperature sensor 12 is fixedly connected to the middle of the inner top surface of the outer casing 1, a pressure sensor 13 is fixedly connected to the middle of the inner top surface of the protective casing 2, a pressure relief channel 15 is fixedly connected to the middle of the rear end of the other side of the outer wall of the protective casing 2, a metal wire mesh 16 is fixedly connected to one side of the inner wall of the pressure relief channel 15, and a pressure relief valve 17 is fixedly connected to the other side of the outer wall of the pressure relief channel 15. The front and rear ends of the outer wall of the outer casing 1 Multiple heat dissipation holes 18 are provided on each of the outer casings. A control panel 19 is fixedly connected to the upper part of the rear end of the outer casing 1. This electrical equipment status monitoring device effectively absorbs the heat generated by the electrical equipment inside the protective casing 2 during operation by setting up a coolant circulation system and using a protective casing 2 made of thermally conductive material. When the temperature sensor 12 detects that the internal temperature of the outer casing 1 exceeds a predetermined value, the control panel 19 automatically starts the servo motor 6 to drive the cooling fan 5 to operate. The air blown out by the cooling fan 5 passes through the coolant pipe 7 to form a cooler air, which is directly blown onto the protective casing 2, thereby reducing the overall temperature, ensuring that the equipment operates within a safe temperature range, extending the equipment life and improving operational stability. A pressure relief channel 15 is set in the protective casing 2. When the electrical equipment fails, it may cause gas decomposition and temperature rise, which may lead to an increase in internal air pressure. The pressure relief channel 15 extends through the outer casing 1 to the outside of the device to release excess pressure, thereby protecting the safety of the equipment and the surrounding environment and preventing serious accidents caused by internal explosion or excessive pressure.

[0036] Reference Figure 3-5Each cooling fan 5 has a drive wheel fixedly connected to the end furthest from the column 3. The upper drive wheels are all fixedly connected to the output end of the servo motor 6. Each drive wheel has a belt fitted around its outer wall, enabling one servo motor 6 to drive multiple cooling fans 5 simultaneously. This simplifies the power system structure, reduces the number of motors used, and lowers equipment costs and energy consumption. The outlet of the coolant tank 8 and the inlet of the circulation pump 9 are connected by a connecting pipe 10. This pipe 10 connects the coolant tank 8 and the circulation pump 9, ensuring that the coolant can flow smoothly from the coolant tank 8 to the circulation pump 9, achieving efficient coolant circulation. The lower end of one side of the coolant pipe 7 is connected to the lower end of the rear coolant pipe 7 via a connecting pipe 11. The connecting pipe 11 connects the front and rear coolant pipes 7, creating a smoother circulation loop. Driven by the circulation pump 9, the coolant flows from the coolant tank 8, through the circulation pump 9, the rear coolant pipe 7, the connecting pipe 11, and the front coolant pipe 7, finally returning to the coolant tank 8, forming a closed loop. The lower end of the other side of the front coolant pipe 7 is connected to the coolant tank 8 via a connecting pipe 14. The lower end of the other side of the rear coolant pipe 7 is connected to the circulation pump 9 via a connecting pipe 14. The coolant flows from the coolant tank 8... The coolant flows out, is pressurized by the circulation pump 9, and enters the front coolant pipe 7. After absorbing heat from inside the protection box 2, it flows back to the coolant tank 8 through the second connecting pipe 14. At the same time, the coolant in the rear coolant pipe 7, after absorbing heat, returns to the circulation pump 9 through the second connecting pipe 14 to re-enter the circulation. This design ensures that the coolant flows continuously throughout the system, effectively removing the heat generated during equipment operation. The outer wall of the pressure relief channel 15 penetrates the middle of the lower end of the other side of the outer casing 1. By setting the pressure relief channel 15 in the middle of the lower end of the other side of the outer casing 1, when the gas inside the protection box 2 decomposes and the temperature rises due to electrical equipment failure, the pressure relief channel 15 is used to relieve the heat generated during equipment operation. When the internal air pressure increases abnormally due to high pressure, the pressure relief channel 15 at the lower end can quickly discharge the high-pressure gas. The protective box 2 is made of heat-conducting plate, which can quickly absorb and conduct the heat generated by the internal electrical equipment during operation, thus improving heat dissipation efficiency. The front and rear ends of one side of the outer wall of the outer box 1 are rotatably connected to the outer box door 20, and the front end of one side of the outer wall of the protective box 2 is rotatably connected to the inner box door 4, providing convenient maintenance and operation interfaces. By facilitating maintenance and repair, the operability of the equipment is improved, the sealing of the equipment is enhanced, the safety of the equipment is improved, and the installation and commissioning of the equipment are facilitated.

[0037] Working Principle: This electrical equipment status monitoring device achieves efficient heat dissipation through the synergistic action of the coolant circulation system and the cooling fan 5. Driven by the circulation pump 9, the coolant circulates through the coolant pipe 7, absorbing the heat generated by the operation of the electrical equipment inside the protection box 2. When the temperature sensor 12 detects that the internal temperature of the outer casing 1 exceeds the preset value, the control panel 19 automatically starts the servo motor 6, driving the cooling fan 5 to operate. The air blown out by the fan passes through the coolant pipe 7 to form cold air, which is then blown towards the protection box 2 to further reduce its temperature, ensuring stable operation of the equipment within a safe temperature range, extending the equipment's lifespan and improving operating efficiency. If the electrical equipment malfunctions, it may cause gas decomposition and temperature rise, which in turn increases the internal pressure. The pressure relief channel 15 penetrates through the outer casing. 1. Extending to the outside of the device, excess pressure is released. During normal operation, the pressure relief valve 17 is closed to prevent gas or liquid leakage inside the equipment. When the gas inside the electrical equipment expands rapidly or the pressure rises abnormally due to a fault, the pressure sensor 13 detects the pressure change and transmits the signal to the control panel 19. When the pressure reaches the set opening pressure of the pressure relief valve 17, the control panel 19 opens the pressure relief valve 17, and the high-pressure gas inside the equipment is quickly discharged to the external safe area through the pressure relief channel 15. The pressure relief channel 15 is equipped with a metal wire mesh 16. During the pressure relief process, the fireproof mesh prevents flames and sparks from being discharged with the gas, thereby avoiding external explosions or fires. The explosion-proof pressure relief structure can effectively protect the safety of electrical equipment and the surrounding environment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
