Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and more particularly to a temperature monitoring device for electrical equipment. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, and power lines in a power system. Most electrical equipment needs to operate for long periods of time, and the heat generated inside the equipment will accumulate, causing the internal temperature to rise and easily leading to fire. Therefore, it is essential to monitor the temperature of electrical equipment.

[0003] A search revealed Chinese patent CN215004012U, which discloses a temperature monitoring device for electrical equipment. The device includes a supporting base plate with a fixing component and a temperature monitoring component fixedly connected to it. A vertical supporting plate has a fastening screw for the fastening component running through it. A circular baffle and a return spring are installed inside a fixing sleeve, which is movably connected to a supporting rod. A first and second supporting rod are respectively fixedly connected to a magnetic square plate and a fixed suction cup. A transmission motor is fixedly connected to a transmission shaft, and a winding wheel groove is fixedly connected to a flexible steel cable. The flexible steel cable is fixedly connected to a temperature monitor. This patent has the following shortcomings: the temperature monitor can move upwards or downwards, but its range of movement in the left and right directions is small and almost negligible, preventing the device from performing multi-point monitoring of the electrical equipment. Furthermore, the lack of a cooling mechanism means the electrical equipment cannot provide timely self-protection when overheating. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature monitoring device for electrical equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The housing is equipped with a transmission mechanism, a limiting mechanism, and a heat dissipation mechanism. The transmission mechanism and the limiting mechanism are located outside the electrical equipment body. The transmission mechanism consists of a set of first mounting seats fixedly connected to the inner wall of the top of the housing. Each set of first mounting seats has a wound motor fixedly connected to its bottom. The other end of the output shaft of each set of wound motors is fixedly connected to a limiting plate. The outer wall of the output shaft of each set of wound motors is threaded. A flexible steel rope is wound between the outer walls of the output shafts of each set of wound motors. A fixing member is fixedly connected to the outer wall of the flexible steel rope. A controller is fixedly connected to one side of the fixing member. A first hydraulic rod is fixedly connected to the bottom of the controller. An infrared temperature sensor and a distance sensor are provided at the bottom end of the first hydraulic rod.

[0007] Preferably, a set of first mounting seats are all bolted to the inner wall of the rear side of the top of the enclosure, and the set of first mounting seats are respectively located on both sides of the electrical equipment body.

[0008] Preferably, the limiting mechanism is a second mounting base fixedly connected to the inner wall of the top of the housing, a support rod fixedly connected to the bottom of the second mounting base, a set of first spur gears rotatably connected to the outer wall of the bottom end of the support rod, a rotating rod rotatably connected to the top of the controller, a second spur gear fixedly connected to the outer wall of the top end of the rotating rod, the outer wall of the support rod slidingly connected to the outer wall of the flexible steel rope, and the flexible steel rope is located between the set of first spur gears.

[0009] Preferably, the controller is equipped with a warning light and a buzzer on its top, and both the warning light and the buzzer are connected to the controller signal.

[0010] Preferably, the heat dissipation mechanism consists of multiple supports fixedly connected to the inner wall of the bottom of the housing, with the same heat dissipation box fixedly connected to the top of the multiple supports. The top of the heat dissipation box is in close contact with the electrical equipment body. Heat dissipation holes are evenly opened on the top and bottom of the heat dissipation box. A heat dissipation motor is fixedly connected to the inner wall of the bottom of the housing. The output shaft of the heat dissipation motor is poweredly connected to a rotating shaft. The top of the rotating shaft extends into the interior of the heat dissipation box. A clamp is fixedly connected to the outer wall of the rotating shaft. A connecting rod is fixedly connected to the outer wall of the clamp. Multiple heat dissipation fan blades are rotatably connected to the top of the connecting rod.

[0011] Preferably, a third spur gear is fixedly connected to the outer wall of the shaft, and a fourth spur gear is fixedly connected to the bottom of multiple cooling fan blades, with the fourth spur gear meshing with the third spur gear.

[0012] Preferably, an air outlet is provided on the rear side of the box, a second hydraulic rod is fixedly connected to the inner wall of the bottom of the box, a damper is fixedly connected to the top of the second hydraulic rod, the outer walls on both sides of the damper are slidably connected to the inner walls on both sides of the air outlet, and an air inlet is provided at the bottom of the box.

[0013] Preferably, a set of front doors is provided on the front side of the enclosure. The set of front doors are symmetrically arranged and hinged to the enclosure. A display is provided on the outside of the front door, and the display is connected to the controller signal.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. Through the transmission mechanism, a set of wound motors is used to move the controller and infrared temperature sensor outside the electrical equipment body under the pull of flexible steel ropes, which facilitates all-round temperature monitoring around the electrical equipment body. At the same time, the first hydraulic rod is used to move the infrared temperature sensor up and down, making the temperature monitoring more comprehensive and improving the monitoring range and accuracy. The distance sensor is also set up so that the infrared temperature sensor can determine the distance between itself and the bottom inner wall of the box or other wires as it descends, preventing the infrared temperature sensor from colliding and enhancing the stability of the device during temperature monitoring.

[0016] 2. By setting a limiting mechanism, the installation path of the flexible steel rope can be changed using the second mounting base, so that the travel path of the infrared temperature sensor is closer to the shape of the electrical equipment body, improving the accuracy of temperature monitoring. At the same time, the first spur gear meshes with the second spur gear when the fixing part moves to the vicinity of the second mounting base, making the fixing part drive the infrared temperature sensor to turn more smoothly, further enhancing the stability of the device during operation.

[0017] 3. Through the heat dissipation mechanism, the cooling motor drives the rotating shaft to rotate, causing multiple cooling fan blades to rotate around the shaft under the drive of the clamps and connecting rods, which increases the heat dissipation area and improves the heat dissipation efficiency. At the same time, the second hydraulic rod can adjust the height of the damper according to the degree of excessive temperature inside the box, so that the size of the air outlet can be adjusted according to the actual temperature, enhancing the automation level of the device.

Each set of first mounting seats 3 is bolted to the inner wall of the rear top of the housing 1, and the set of first mounting seats 3 are located on both sides of the electrical equipment body 2.

[0027] Meanwhile, the limiting mechanism is a second mounting base 12 fixedly connected to the inner wall of the top of the housing 1. A support rod 13 is fixedly connected to the bottom of the second mounting base 12. A set of first spur gears 14 are rotatably connected to the outer wall of the bottom end of the support rod 13. A rotating rod 15 is rotatably connected to the top of the controller 8. A second spur gear 16 is fixedly connected to the outer wall of the top end of the rotating rod 15. The outer wall of the support rod 13 is slidably connected to the outer wall of the flexible steel rope 6, and the flexible steel rope 6 is located between the set of first spur gears 14. A warning light 17 and a buzzer 18 are provided on the top of the controller 8. Both the warning light 17 and the buzzer 18 are signal connected to the controller 8.

[0028] Meanwhile, the heat dissipation mechanism consists of multiple supports 19 fixedly connected to the inner wall of the bottom of the housing 1, and the same heat dissipation box 20 fixedly connected to the top of the multiple supports 19. The top of the heat dissipation box 20 is in close contact with the electrical equipment body 2. Heat dissipation holes 21 are evenly opened on the top and bottom of the heat dissipation box 20. A heat dissipation motor 22 is fixedly connected to the inner wall of the bottom of the housing 1. The output shaft of the heat dissipation motor 22 is poweredly connected to a rotating shaft 23. The top of the rotating shaft 23 extends into the heat dissipation box 20. A clamp 24 is fixedly connected to the outer wall of the rotating shaft 23. A connecting rod 25 is fixedly connected to the outer wall of the clamp 24. Multiple heat dissipation fan blades 26 are rotatably connected to the top of the connecting rod 25. A third spur gear 27 is fixedly connected to the outer wall of the rotating shaft 23. The same fourth spur gear 28 is fixedly connected to the bottom of the multiple heat dissipation fan blades 26. The fourth spur gear 28 is meshed with the third spur gear 27.

[0029] Meanwhile, an air outlet 29 is provided on the rear side of the housing 1, a second hydraulic rod 30 is fixedly connected to the inner wall of the bottom of the housing 1, and an air damper 31 is fixedly connected to the top of the second hydraulic rod 30. The outer walls on both sides of the air damper 31 are slidably connected to the inner walls on both sides of the air outlet 29. An air inlet 32 ​​is provided at the bottom of the housing 1, and a set of front doors 33 is provided on the front side of the housing 1. The set of front doors 33 are symmetrically arranged and hinged to the housing 1. A display 34 is provided on the outside of the front door 33, and the display 34 is connected to the controller 8 via signal.

[0030] Working principle: When in use, open the front door 33 and place the electrical equipment body 2 on the heat dissipation box 20. Install a set of first mounting seats 3 on the inner wall of the top of the box 1 with bolts, so that the set of first mounting seats 3 are located at the rear of both sides of the electrical equipment body 2 to prevent the infrared temperature sensor 10 from contacting the external wires of the electrical equipment body 2 during descent. Select an appropriate number of second mounting seats 12 and install multiple second mounting seats 12 on the inner wall of the top of the box 1 with bolts, so that they push out the flexible steel rope 6, so that multiple second mounting seats 12 are located outside the electrical equipment body 2 and surround the electrical equipment body 2. At this time, the flexible steel rope 6 should be located outside the electrical equipment body 2 and have a similar shape to the electrical equipment body 2. After installation, close the front door 33, and the electrical equipment body 2 will start to work normally.

[0031] During the operation of the electrical equipment body 2, a set of wound motors 4 start and rotate in opposite directions, causing the fixing member 7 to drive the controller 8 and the infrared temperature sensor 10 to move at a constant speed around the electrical equipment body 2. When the fixing member 7 moves close to the second mounting base 12, the first spur gear 14 and the second spur gear 16 mesh with each other, causing the fixing member 7 to drive the controller 8 to complete the rotation. At the same time, the first hydraulic rod 9 is activated, causing the infrared temperature sensor 10 to move up and down, performing all-round temperature monitoring of the electrical equipment body 2. The distance sensor 11 allows the infrared temperature sensor 10 to determine its proximity to the bottom inner wall of the housing 1 or other surfaces as it descends. The distance between the wires prevents the infrared temperature sensor 10 from colliding, enhancing the stability of the device during temperature monitoring. If the temperature inside the housing 1 is found to be too high during temperature monitoring, the controller 8 controls the cooling motor 22 and the second hydraulic rod 30 to start. The cooling motor 22 drives the rotating shaft 23 to rotate, causing multiple cooling fan blades 26 to rotate around the rotating shaft 23 under the drive of the clamp 24 and the connecting rod 25, increasing the heat dissipation area and improving the heat dissipation efficiency. At the same time, the second hydraulic rod 30 can adjust the height of the damper 31 according to the degree of excessive temperature inside the housing 1, so that the size of the air outlet 29 can be adjusted according to the actual temperature, enhancing the automation level of the device.
