Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model provides a technical solution: a power distribution box for a construction site, including a box body 8, the upper side of the box body 8 is provided with a buffer plate 1, and the buffer plate 1 and the box body 8 There is a buffer device between them, and the left and right sides of the box body 8 are provided with a first ventilation duct 10, the first ventilation duct 10 is provided with a first dust-proof net 7, and the top of the first dust-proof net 7 is arranged There is a first activated carbon filter screen 6, the bottom end of the first ventilation duct 10 is provided with an air inlet 19, the motor 20 is fixed in the air inlet 19 through a bracket, and the output shaft end of the motor 20 is provided with a ventilation fan 9. The upper ends of the left and right sides of the box body 8 are provided with air inlet holes 18, the air inlet holes 18 communicate with the upper end of the first ventilation duct 10, and the bottom of the box body 8 is provided with a second ventilation duct 14, The bottom of the box body 8 is provided with an air outlet 13, and the air outlet 13 communicates with the middle part of the second ventilation duct 14, and the left and right ends of the second ventilation duct 14 are all provided with an air outlet 11, two The air outlets 11 are provided with a second dust-proof net 12 , and a second activated carbon filter 5 is disposed above the second dust-proof net 12 .

The buffer plate 1 is arranged on the upper side of the box body 8, which acts as a buffer, and can prevent falling stones from falling from the building and damaging the box body 8. Since the electrical components in the box body 8 run for a long time and generate heat seriously, the box body 8 will The air inlet hole 18 on the side communicates with the first ventilation duct 10, the motor 20 in the air inlet 19 is started, the ventilation fan 9 is rotated, and the outside air is sucked into the first ventilation duct 10, and the air is filtered through the first dustproof net 7. The particles and dust in the air pass through the first activated carbon filter 6, absorbing the water vapor in the air, and then enter the box body 8 through the air inlet 18 to ventilate and cool the internal electrical components, and the cooled hot air passes through The air outlet 13 is discharged into the second ventilation duct 14, and then discharged from the air outlets 11 on the left and right sides of the second ventilation duct 14, so that an air circulation is formed, and the heat in the box body 8 is taken away by the circulating air. Realize ventilation and heat dissipation, and prevent dust and water vapor from entering the box body 8 and causing damage to the internal electrical components; in addition, when the motor in the first ventilation duct 10 is turned off, the outside air may flow from the first ventilation duct 10 and the second ventilation duct at the same time. The second ventilation duct 14 enters, and the second dust-proof net 12 and the second activated carbon filter screen 5 in the second ventilation duct 14 can ensure that the incoming air is filtered.

Specifically, the buffer device includes a telescopic rod 3, a spring 2 and a sleeve 4, the upper end of the telescopic rod 3 is fixedly connected to the lower end of the buffer plate 1, and the lower end of the telescopic rod 3 is embedded in the sleeve 4, The outside of the telescopic rod 3 is covered with a spring 2, the upper end of the spring 2 is fixedly connected with the buffer plate 1, the lower end of the spring 2 is fixedly connected with the upper end of the sleeve 4, and the lower end of the sleeve 4 is fixedly connected with the upper end of the box body 8.

The telescopic rod 3 is provided with a spring 2, which can buffer the up and down sliding of the telescopic rod 3, and the sleeve 4 can slide the telescopic rod 3 to prevent the buffer plate 1 from being overstressed and the spring 2 from being over-compressed It cannot be restored and loses its buffering effect.

Specifically, a plurality of glass observation windows 17 are provided on the front wall of the box body 8 . The glass observation window 17 is convenient for personnel to view the situation of the electrical components inside the box body 8 from the outside, which is simple and practical.

Specifically, a protective door 16 is provided on the front end of the box body 8 , and the protective door 16 is arranged on the right side of the front end surface of the box body 8 by hinge rotation. Since the front wall of the box body 8 is provided with a plurality of glass observation windows 17, which are easily damaged by building flying stones, the protective door 16 plays a protective role, and is convenient for personnel to open and close by hinge rotation.

Specifically, the first dust-proof net 7 and the first activated carbon filter 6 are detachably arranged on the first ventilation duct 10, and the second dust-proof net 12 and the second activated carbon filter 5 are detachably arranged on the second Inside the ventilation duct 14. After the dust-proof net and activated carbon filter are used for a long time, particles and dust will continue to accumulate on them, which will cause poor ventilation and fail to achieve heat dissipation. It will also affect the filtration of external air and cause dust and water vapor to enter the box. 8. It will cause damage to the internal electrical components, so the detachable setting is convenient for personnel to clean and replace frequently.

The working principle of the utility model is: the ventilation fan quickly sends the air into the first ventilation duct, the first dust-proof net in the first ventilation duct filters the dust and particulate matter in the air, and the activated carbon filter net absorbs the water vapor in the air, The filtered air enters the distribution box to ventilate and dissipate the electrical components in the box, and finally the hot air is discharged from the air outlet in the second ventilation duct.
