Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-3, an outdoor distribution box comprises a vertical rectangular box body 2 with a rain shield 1 at the top, four support legs 14 are fixed at the bottom of the box body 2, a wire through hole 16 is opened at the bottom of the box body 2, an opening sliding door 3 is arranged on one side wall of the box body 2, a plurality of vent holes 4 are opened on the side walls of the box body 2 at the two sides of the opening sliding door 3, the vent holes 4 on the side walls of the box body 2 at the two sides of the opening sliding door 3 are opposite to each other and correspond to each other, the natural wind entering the box body 2 can be blown out from the other side of the box body 2 rapidly by the mode, the probability that the natural wind entering the box body 2 from the vent hole 4 on the side wall of the box body 2 hits the side wall of the opposite side of the box body 2 in the process of sending out the box body 2 is greatly reduced, thereby ensuring the smooth sending out of the natural wind, thereby further improving the efficiency of taking out hot air in the box body 2 and further improving the heat dissipation efficiency. Every the position in ventilation hole 4 all is equipped with an air guide component 5, every air guide component 5 all contains one and wears to establish corresponding ventilation hole 4 and can wind self axis pivoted installation axle 5a, one and fixes on installation axle 5a and be located the air guide block 5b in the 2 outsides of box and a wind-receiving plate 5c of fixed connection on air guide block 5 b. The air guide block 5b is provided with a strip-shaped air guide groove 6, the bottom of the strip-shaped air guide groove 6 is inclined, and the ventilation volume of one end, close to the corresponding vent hole 4, of the strip-shaped air guide groove 6 is larger than that of the other end of the strip-shaped air guide groove 6. This kind of mode can further lead to the natural wind to make and enter into the natural wind in the bar-shaped air guide groove 6 is carried to the ventilation hole 4 that corresponds as much as possible, does benefit to the utilization efficiency to the natural wind, the face perpendicular to box 2 lateral wall of corresponding position of board 5c receives the wind board 5c, and receives the wind board 5c and is located the opposite side relative with bar-shaped air guide groove 6 on air guide block 5b for rotate and drive installation axle 5a synchronous rotation so that the opening that bar-shaped air guide groove 6 deviates from air guide block 5b one end is in the windward position that can lead-in ventilation hole 4 with external wind when receiving the wind.

As shown in fig. 1, 4 and 5, each at least one connecting rod 7 is fixed on the inner wall of the vent hole 4, the connecting rod 7 is fixedly connected with a first bearing 8 and is fixedly connected to the outer wall of the first bearing 8, the installation shaft 5a is fixedly arranged in a center hole penetrating through the first bearing 8 and extends into the box body 2, the mode provides a simpler installation mode for the installation shaft 5a, which is beneficial to reducing the manufacturing cost, in addition, the arrangement of the first bearing 8 can greatly reduce the friction generated in the rotation process of the installation shaft 5a, and further improves the rotation sensitivity of the installation shaft 5a, so that the installation shaft 5a can rotate equally when the wind power of the external natural wind is small, and the utilization efficiency of the natural wind is further improved. Lie in box 2 installation axle 5a tip is opened along circumference has annular mounting groove 15, install a second bearing 9 in this mounting groove 15, support 17 of fixed connection on the 9 outer walls of this second bearing, an installation pole 10 with installation axle 5a collineation of fixed connection on this support 17, the equipartition has multi-disc flabellum 11 on the same circumference lateral wall of this installation pole 10, this kind of mode can further carry out the rectification to the natural wind that enters into in box 2 through ventilation hole 4, thereby be favorable to keeping entering into the powerful of box 2 interior wind-force, and then can blow out in box 2 fast, improve the efficiency of the inside and outside heat exchange of box 2. The end part of the air guide block 5b close to the vent hole 4 is fixedly connected with a guide block 13, and the guide block 13 is provided with a guide groove 12 communicated with the strip-shaped air guide groove 6 so as to guide natural air entering the strip-shaped air guide groove 6 to be delivered into the vent hole 4 in a direction vertical to the plane of the corresponding vent hole 4. The mode mainly ensures that natural wind is blown out of the strip-shaped wind guide groove 6 and then fully blown into the box body 2 as much as possible, reduces the bad phenomenon that the natural wind entering the strip-shaped wind guide groove 6 is blown out of a gap between the wind guide block 5b and the side wall of the corresponding box body 2, and further improves the utilization efficiency of the natural wind.

The working principle is as follows: placing the box body 2 at a predetermined outdoor position, when external natural wind blows on the wind receiving plate 5c in the structure of the wind guiding assembly 5, and when external natural wind blows on the wind receiving plate 5c in a direction perpendicular to the plate surface of the wind receiving plate 5c, the wind receiving plate 5c drives the mounting shaft 5a to rotate around the axis of the mounting shaft 5a, at this time, the wind guiding blocks 5b rotate synchronously, when the external natural wind blows the wind receiving plate 5c to the wind receiving plate 5c, the plate surface of which is parallel to the wind direction of the natural wind and maintains the position state, the strip wind guiding grooves 6 on the strip wind guiding block 5b rotate to the windward position, the external natural wind blows into the strip wind guiding grooves 6, the wind direction is changed under the action of the strip wind guiding grooves 6, the natural wind in the strip wind guiding grooves 6 flows into the corresponding guiding grooves 12, and the natural wind blown from the guiding grooves 12 contacts and drives the corresponding fan blades 11 to rotate, the fan blades 11 rotate to further rectify natural wind blown into the box body 2 and further blow into the box body 2, the natural wind entering the box body 2 starts to radiate the space in the box body 2, and then the natural wind entering the box body 2 is blown out from the ventilation hole 4 on the opposite side, so that hot air in the box body 2 is taken out, and the purpose of radiating the box body 2 is achieved; when external natural wind blows to the wind receiving plate 5c at a certain inclination angle, the wind receiving plate 5c drives the mounting shaft 5a to rotate around the axis of the mounting shaft 5a, at this time, the wind guide block 5b rotates synchronously, when the external natural wind blows the wind receiving plate 5c to the wind receiving plate 5c with the plate surface parallel to the wind direction of the natural wind and maintains the position state, the bar-shaped wind guide grooves 6 on the bar-shaped wind guide block 5b rotate to the windward position, the external natural wind blows into the bar-shaped wind guide grooves 6 and changes the wind direction under the action of the bar-shaped wind guide grooves 6, the natural wind in the bar-shaped wind guide grooves 6 circulates to the corresponding guide grooves 12, the natural wind blowing from the guide grooves 12 contacts and drives the corresponding fan blades 11 to rotate, the fan blades 11 rotate to further rectify the natural wind blowing into the box body 2, then blows into the box 2, the natural wind entering the box 2 starts to radiate the space in the box 2, then blows out the natural wind entering the box 2 from the ventilation hole 4 on the opposite side, and then brings out the hot air in the box 2, so as to radiate the box 2, according to the wind direction of the external natural wind, the external natural wind may blow in from the ventilation hole 4 on one side of the side wall of the box 2, then blows out from the ventilation hole 4 on the other side, or blows in from the ventilation hole 4 on the other side of the side wall of the box 2, and then blows out from the ventilation hole 4 on the opposite side.
