Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the temperature early warning device for maintenance of explosion-proof electrical equipment of the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 8 As shown, the utility model is a temperature warning device for maintenance of explosion-proof electrical equipment, comprising a pair of mounting plates 1, the mounting plates 1 are fixed on the equipment to be monitored, and an audible and visual alarm 14 is installed on the upper end of the mounting plates 1, the audible and visual alarm 14 is used to generate sound and light for early warning alarm.

[0029] In order to monitor the temperature of the equipment, a first slide groove 11 is opened on a pair of mounting plates 1, and a temperature measuring mechanism 2 is slidably connected in the first slide groove 11. The temperature measuring mechanism 2 includes two sliders 25 that slide in the two first slide grooves 11 respectively. A horizontal plate 21 is rotatably arranged between the two sliders 25. A plurality of temperature sensors 22 are installed on the horizontal plate 21. The temperature sensor 22 is installed on the horizontal plate 21, and the temperature of the equipment is detected by the temperature sensor 22.

[0030] Furthermore, a heat conducting plate 23 is connected to the lower side of the temperature sensor 22 , and the heat conducting plate 23 is fitted with the device to prevent the temperature sensor 22 from directly contacting a high temperature location, thereby extending the service life of the temperature sensor 22 .

[0031] Among them, the rotating shafts at both ends of the horizontal plate 21 respectively penetrate the two sliders 25 and are connected to the two gears 24. At the same time, a rack 13 is set on the side of the first slide groove 11 close to the upper end. When the slider 25 slides downward, the rack 13 engages with the gear 24, so that the gear 24 turns over with the horizontal plate 21, and the length of the rack 13 is sufficient for the gear 24 to rotate 180 degrees, that is, the heat conducting plate 23 is turned upward, so that the heat conducting plate 23 is away from the high temperature and the heat dissipation is convenient.

[0032] Furthermore, an extension plate 15 is provided on one side of the mounting plate 1 , a limit rod 5 is fixedly provided at one end of the extension plate 15 , a heat dissipation mechanism 3 is slidably connected to the limit rod 5 , and the heat dissipation mechanism 3 is used to cool the temperature measuring mechanism 2 .

[0033] Specifically, the heat dissipation mechanism 3 includes a pair of movable blocks 31, one of which is slidably connected to the limit rod 5, and the other movable block 31 is threadedly connected to the first screw rod 4 that is rotatably connected to the other end of the extension plate 15. A cooling fan 32 is rotatably connected between the pair of movable blocks 31, and the cooling fan 32 is flipped to be tilted so that the cooling fan 32 blows air to dissipate heat from the heat conducting plate 23, thereby quickly reducing the temperature of the heat conducting plate 23.

[0034] In addition, a sliding hole 34 is opened on one side of the moving block 31, and a limiting sleeve 33 is slidably set in the sliding hole 34. The limiting sleeve 33 is engaged with the protrusions on both sides of the cooling fan 32. The cooling fan 32 is limited by the limiting sleeve 33 to keep the cooling fan 32 stable. When the cooling fan 32 needs to be rotated, the limiting sleeve 33 is slid into the sliding hole 34 or removed, so that the cooling fan 32 can rotate smoothly.

[0035] In order to make the heat conducting plate 23 move upward automatically, a second slide groove 12 is opened on one side of the mounting plate 1. A second screw rod 6 is rotatably arranged in the second slide groove 12. The second screw rod 6 is driven by a motor. The second screw rod 6 is threadedly connected to one of the sliders 25. When the second screw rod 6 rotates, the slider 25 moves with the slider 25, and then the cross plate 21 moves automatically with the temperature sensor 22.

[0036] In order to make the cooling fan 32 move upward along with the heat conducting plate 23, the gear three 61 is connected to the lower end of the second screw rod 6, and a double-headed gear 42 is rotatably set at one end of the extension plate 15. One end of the double-headed gear 42 is meshed with the gear three 61, and the other end of the double-headed gear 42 is meshed with the gear two 41 connected to the lower end of the first screw rod 4. When the second screw rod 6 rotates, the two ends of the double-headed gear 42 are respectively meshed with the gear two 41 and the gear three 61, so that the first screw rod 4 rotates. Through the limiting of the limiting rod 5, the cooling fan 32 moves upward, so as to better cool the heat conducting plate 23.

[0037] It is worth mentioning that a touch block 26 is arranged on the upper side of the slider 25, a groove 16 is opened at the top of the first slide groove 11, a spring 17 is arranged in the groove 16, one end of the spring 17 is connected to the pressure sensor 18, when the second screw rod 6 rotates to make the slider 25 move upward, after the touch block 26 contacts with the pressure sensor 18, the pressure sensor 18 transmits a signal to the controller on the back of the cooling fan 32, and the controller receives the signal and controls the sound and light alarm 14 to sound an alarm.

[0038] A temperature warning device for maintenance of explosion-proof electrical equipment works as follows: when the heat conducting plate 23 is fitted with the electrical equipment, the temperature of the equipment is transmitted to the temperature sensor 22. When the temperature sensor 22 detects that the temperature exceeds the safety threshold, the motor starts, prompting the second screw rod 6 to rotate, causing the slider 25 to move upward with the cross plate 21, and through the engagement of the gear 1 24 and the rack 13, the cross plate 21 is flipped, and then the heat conducting plate 23 is rotated upward to facilitate the heat dissipation of the heat conducting plate 23 and the temperature sensor 22. At the same time, when the first screw rod 4 rotates, the double-headed gear 42 is engaged with the gear 2 41 and the gear 3 61, so that the first screw rod 4 rotates, and then the cooling fan 32 moves upward to cool the heat conducting plate 23 and the temperature sensor 22, thereby extending the service life of the two.
