[0002] The watt-hour meter box is an integrated component of the watt-hour meter, box body, and various circuit breakers, which can protect the watt-hour meter and circuit breaker. With the rapid development of industries such as petroleum, chemical industry, military industry, engineering, and coal mining, explosion-proof watt-hour meter boxes are more and more widely used in production, warehousing, and rescue, and there are more and more varieties. The watt-hour meter box has many electronic components inside, so it is very easy to heat up during use, and the existing watt-hour meter box usually simply sets vents on the side wall of the box body for heat dissipation. Such a setting has a poor heat dissipation effect. If the temperature in the box is too high, it may cause the electronic components to have a reduced life or even damage. For this reason, we propose a coal mine watt-hour meter box. Utility Model Content

DETAILED DESCRIPTION
[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0025] Embodiment 1:
[0026] like Figure 1-8 As shown, a coal mine electric meter box of the utility model comprises a box body 1, a plurality of electric meters 2 are arranged in the box body 1, a plurality of air outlets 4 are arranged on the right side of the box body 1, and an air guide mechanism is arranged on the left side of the box body 1;
[0027] The air guide mechanism includes a slide bar 5, a slide groove 6 is provided in the box body 1, the slide bar 5 is slidably arranged inside the slide groove 6, a driving assembly is provided between the slide bar 5 and the box body 1, the slide bar 5 is provided with a plurality of hinge seats 7, the plurality of hinge seats 7 are hinged with a rotating plate 8, the plurality of rotating plates 8 are fixedly provided with a connecting plate 14 on the side away from the slide bar 5, the plurality of connecting plates 14 are provided with a through groove 9, the box body 1 is provided with two rectangular plates 10, the two rectangular plates 10 are respectively located above and below the slide bar 5, a plurality of circular shafts 11 are fixedly provided between the two rectangular plates 10, the plurality of circular shafts 11 are respectively slidably connected with the plurality of through grooves 9, the plurality of connecting plates 14 are fixedly provided with an air guide plate 12, and a plurality of fans 13 are provided above and below the slide groove 6;
[0028] During the use of the device, a number of electric meters 2 will emit heat to increase the temperature inside the box 1, and a number of fans 13 will be started. Due to the setting of the air outlet 4, the air flow will flow into the box 1 from the left side and out from the right side of the box 1. The driving component will be turned on, and the driving component will drive the slide bar 5 to move back and forth inside the slide groove 6. When the slide bar 5 moves backward, the end of the rotating plate 8 moves backward under the drive of the slide bar 5. Since the rotating plate 8 and the slide bar 5 are hinged, the round shaft 11 slides in the through groove 9 and limits the connecting plate 14, so that the connecting plate 14 and the rotating plate 8 as a whole swing backward with the round shaft 11 as the center of the circle. At the same time, the round shaft 11 Slide in the through slot 9. When the slide bar 5 moves forward, the end of the rotating plate 8 moves forward, but the connecting plate 14 is limited by the cooperation of the circular shaft 11 and the through slot 9. The connecting plate 14 and the rotating plate 8 swing forward with the circular shaft 11 as the center of the circle. In this way, the slide bar 5 moves forward and backward in the slide slot 6 to drive the connecting plate 14 to swing forward and backward, thereby driving a plurality of air guide plates 12 to swing forward and backward, and guide the wind blown by the fan 13 to blow forward and backward alternately, so as to evenly cool the inside of the box 1, so that the heat dissipation effect inside the box 1 is better, and the damage of electronic components caused by excessive temperature inside the box 1 is effectively avoided;
[0029] The utility model sets a driving component to drive the slide bar 5 to move forward and backward, thereby driving the rotating plate 8 to move forward and backward, and sets a circular shaft 11 and a through groove 9 to limit the connecting plate 14, so that the wind guide plate 12 can swing forward and backward, thereby guiding the airflow generated by the fan 13. Due to the position setting of the air outlet 4, the wind blows through the inside of the box from left to right. The above setting enables the wind to blow back and forth, and the inside of the box 1 is more evenly affected by the wind as a whole, and the heat dissipation effect is better, which effectively avoids the reduction of the life of electronic components due to excessive temperature, and is extremely practical.
[0030] The driving assembly includes a square box 21, which is arranged on the left side of the box body 1. A swing rod 22 is rotatably arranged at the lower end of the square box 21. The swing rod 22 is provided with a limit groove 23. A disc 24 is rotatably arranged at the upper end of the square box 21. A cylinder 25 is fixedly arranged at the lower edge of the disc 24. The cylinder 25 is slidably connected with the limit groove 23. A fan-shaped tooth 26 is arranged at one end of the swing rod 22 close to the box body 1. The box body 1 is provided with a square groove 29 connected with the slide groove 6. The fan-shaped tooth 26 is located in the square groove 29. The slide rod 5 is provided with a plurality of latch teeth 27 meshing with the fan-shaped tooth 26. A motor 28 is fixedly arranged at the upper end of the square box 21. The output shaft of the motor 28 extends into the square box 21 and is transmission-connected with the disc 24.
[0031] When the slide bar 5 needs to be moved, the motor 28 is started. The operation of the motor 28 drives the disc 24 to rotate. The rotation of the disc 24 drives the cylinder 25 to make a circular motion with the center of the disc 24 as the center. Since the middle part of the swing rod 22 is connected to the inside of the square box 21 by rotation, the cylinder 25 slides inside the limit groove 23, and cooperates with the limit groove 23 to drive the swing rod 22 to swing back and forth, so that the swing rod 22 drives the fan-shaped teeth 26 to swing, and the fan-shaped teeth 26 drive the slide bar 5 to slide back and forth in the slide groove 6 through the matching latch teeth 27 on the slide bar 5. This arrangement realizes the reciprocating swing of the slide bar 5 inside the slide groove 6, so that the slide bar 5 can drive the wind guide plate 12 to swing and guide the wind, and the structure is reasonable.
[0032] An observation window 41 is provided at the front end of the box body 1; the user can observe the indication of the electric meter 2 through the observation window 41, which is very convenient.
[0033] Several air outlets 4 are provided with filters 51; there is much dust in the coal mine, and the filter 51 can prevent the dust from entering the interior of the box 1, keep the interior of the box 1 clean, and avoid the dust from causing poor heat dissipation inside the box 1. At the same time, the dust will also affect the reading of the meter.
[0034] Embodiment 2:
[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, as an improvement of the previous embodiment, four rectangularly distributed mounting ears 31 are provided at the upper and lower ends of the box body 1, and threaded holes are provided in the four mounting ears 31, and bolts 32 are threadedly connected in the four threaded holes;
[0036] When the device needs to be installed, the box 1 is pre-placed in the area to be installed, and four bolts 32 are screwed into the threaded holes to fix the box 1. The four rectangularly distributed mounting ears 31 are evenly stressed, which can make the box 1 more stably fixed and not easy to loosen.
[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
