[0012] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] As shown in the accompanying drawings, the utility model is a thermal alarm device for a modular transformer in an oil and gas electrical room, comprising a left linear motion output mechanism and a right linear motion output mechanism respectively arranged on the left and right sides of a transformer 5, and the transformer 5 is placed on a transformer base 6 fixed to the ground.

The front slider 1-3-1 is connected; the rear guide rail slider pair includes a rear guide rail 1-2-2 and a rear slider 1-3-2 connected to the rear guide rail 1-2-2 for sliding up and down. A first servo motor 1-8 is fixed to the bottom of the support frame 1-1, and the output shaft of the first servo motor 1-8 is fixedly connected to the lower end of the long lead screw 1-6 arranged in the vertical direction through a first coupling 1-7. The upper end of the long lead screw 1-6 is installed in the first bearing seat 1-5, and the first bearing seat 1-5 is fixed on the support frame 1-1. A lead screw nut 1-4 is rotatably installed on the long lead screw 1-6; of course, the left linear motion output mechanism and the right linear motion output mechanism can also adopt linear motors and other mechanisms.

[0015] The left movable temperature measuring platform 2 and the right movable temperature measuring platform 7 both include a lower U-shaped plate, as shown in the embodiment of the figure: a front support plate 2-1-1 and a rear support plate 2-1-2 and a connecting plate 2-4 connected between the front support plate 2-1-1 and the rear support plate 2-1-2. The web of the lower U-shaped plate (the connecting plate 2-4 in the embodiment of the figure) is respectively fixed on the upper and lower motion output ends of the left linear motion output mechanism and the upper and lower motion output ends of the right linear motion output mechanism, as shown in the embodiment of the figure: it is respectively fixed on the slider (front slider 1-3-1) of the front guide rail slider pair and the slider (rear slider 1-3-2) of the rear guide rail slider pair of the left vertical screw transmission system 1 and the slider (front slider 1-3-2) of the front guide rail slider pair of the right vertical screw transmission system 8. The platform guide rail slider pair is mounted on the two wings of the horizontally arranged lower U-shaped plate. As shown in the embodiment shown in the figure, the front guide rail 2-2-1 and the rear guide rail 2-2-2 are fixed to the top walls of the front support plate 2-1-1 and the rear support plate 2-1-2, respectively. The front slider 2-3-1 and the rear slider 2-3-2 are slidably connected to the front guide rail 2-2-1 and the rear guide rail 2-2-2, respectively. The bottom walls of the front and rear wings of a U-shaped temperature measuring plate 2-5 are fixedly connected to the top walls of the sliders of the front and rear platform guide rail slider pairs, respectively. That is, the temperature measuring plate 2-5 is fixed to the front slider 2-3-1 and the rear slider 2-3-2.

[0016] The bottom wall of the front wing of the U-shaped temperature measurement plate 2-5 is connected to the top wall of the front wing of the lower U-shaped plate via a screw-nut pair. The output shaft of the screw-nut pair is connected to one end of a short, horizontally arranged screw via a coupling. The other end of the short screw 2-7 is secured to a second bearing 2-8, which is secured to a second bearing block 2-9. The second bearing block is secured to the top wall of the front wing of the lower U-shaped plate. Driven by the screw-nut pair, the U-shaped temperature measurement plate can move left and right and surround the transformer. Temperature sensors 2-10 are mounted on the inner walls of the front and rear wing of the U-shaped temperature measurement plate, respectively. As shown in one embodiment in the figure, a second servo motor 2-6 is mounted on the rear support plate 2-1-2.

[0017] The working process of this device is:

[0018] When the transformer 5 begins operation, the left and right movable temperature measurement platforms 2 and 7 move vertically, driven by the left and right vertical screw drive systems 1 and 8, respectively. The output shaft of the first servo motor 1-8 rotates the long lead screw 1-6 via the first coupling 1-7. The lead screw nut 1-4 then drives the front slider 1-3-1, the rear slider 1-3-2, and the connecting plate 2-4 in the vertical direction, causing the left movable temperature measurement platform 2 (and the right movable temperature measurement platform 7 to move synchronously therewith) to move vertically, stopping when it reaches the middle of the transformer 5.

[0019] Afterward, the temperature measurement plates on the left and right movable temperature measurement platforms 2 and 7 move closer together, forming a closed loop that surrounds the transformer 5. The second servo motor 2-6 rotates the short lead screw 2-7, which in turn drives the front slide 2-3-1 and rear slide rail 2-3-2 to the right, causing the temperature measurement plate 2-5 to move rightward and stop when it reaches the designated position.

[0020] Next, temperature sensor 2-10 on temperature measurement plate 2-5 of left mobile temperature measurement platform 2 begins measuring the transformer surface temperature (the right temperature sensor measures simultaneously). Simultaneously, left mobile temperature measurement platform 2 and right mobile temperature measurement platform 7, driven by left vertical screw drive system 1 and right vertical screw drive system 8, respectively, move vertically again, allowing temperature sensor 2-10 to measure temperatures at various locations on the transformer surface.

[0021] If the temperature is below the specified range, the surface will continue to be traversed according to the normal process. Once the measured temperature exceeds the specified temperature, an alarm will be issued and the heat dissipation device 4 will react in real time until the temperature drops below the specified temperature. The alarm will be lifted and the device will continue to measure.
