Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 1 to 4, the present embodiment provides a distribution box, which mainly includes: box 11, heat dissipation mechanism and anti-blocking mechanism.

An openable and closable door 111 is installed at one side of the box 11, and an observation window 112 is provided on the door 111 so as to observe the operating state of the electronic components inside the box 11.

The heat dissipation mechanism includes an air inlet 121 and an air outlet 122, the air inlet 121 is connected to the lower portion of the left side of the box 11, the air outlet 122 is connected to the upper portion of the right side of the box 11, and both the inlet of the air inlet 121 and the outlet of the air outlet 122 face downward. The outlet 122 is provided with a check valve 123 and an exhaust fan 124.

The anti-blocking mechanism comprises a dust filtering box 131, the dust filtering box 131 is fixed on the left side of the box body 11, the upper end of the air inlet 121 is connected to the lower portion of the left side of the dust filtering box 131, and the top of the dust filtering box 131 is communicated with the box body 11 through a guide pipe 132. The middle part of the inner side of the dust filtering box 131 is provided with a dust baffle plate 133, the dust baffle plate 133 is obliquely arranged, and a plurality of dust baffle plates 133 are arranged in the dust filtering box 131 at intervals. The dust screen 134 is installed on the upper portion of the inner side of the dust filtering box 131.

After passing through the air inlet 121, the dust filter 131 and the box 11 in sequence, the air flow is discharged from the air outlet 122, and takes away heat in the box 11, so as to facilitate heat dissipation of electronic components in the box 11. The inlet of the air inlet 121 faces downwards, so that the raised dust is not easy to fall into the air inlet 121, and the raised dust is not easy to enter the dust filtering box 131 and the box body 11. Since less dust is introduced into the dust box 131, the possibility of the dust screen 134 being clogged is reduced. Even if part of the raised dust enters the air inlet 121 along with the air flow, the raised dust will impact on the dust baffle 133 and then fall to the bottom of the dust filtering box 131, so as to further reduce the probability that the dust screen 134 is blocked, and the dust screen 134 can reduce the raised dust entering the box 11, thereby preventing the raised dust from affecting the normal operation of the electronic components in the box 11.

The bottom of the dust filtering box 131 is connected with a dust exhaust pipe 135, a movable tongue 136 is slidably arranged in the dust exhaust pipe 135, the movable tongue 136 is connected with the dust exhaust pipe 135 through a pressure spring 137, a dust outlet 138 is formed in the right side of the dust exhaust pipe 135, and the dust outlet 138 is located below the movable tongue 136. When the dust accumulated on the movable tongue 136 reaches a certain amount, the movable tongue 136 moves downwards to the dust outlet 138, and then the dust on the movable tongue 136 can be discharged from the movable tongue 136.

As shown in fig. 3 and 4, the upper side of the movable tongue 136 is disposed obliquely so as to better discharge the dust on the movable tongue 136.

As shown in fig. 3 and 4, a dust guide block 139 is installed in the dust outlet 138, and the upper side of the dust guide block 139 and the upper side of the movable tongue 136 are both inclined to the lower right, so as to better discharge the dust on the movable tongue 136.

The right side of the lower end of the air inlet 121 is provided with a baffle 125 to prevent the dust discharged from the dust outlet 138 from entering the air inlet 121 again.

The top of the dust filtering box 131 is inserted with a guide rod 141, the top of the guide rod 141 is fixed with a driving block 142, the upper side of the driving block 142 is arc-shaped, the lower end of the guide rod 141 is fixedly provided with a knocking head 143, the middle of the guide rod 141 is fixed with a limiting block, the guide rod 141 is sleeved with a return spring 144, one end of the return spring 144 is connected with the limiting block, and the other end of the return spring is connected with the dust filtering box 131. In the presence of wind, the driving block 142 will move upward under the action of the air flow. This is because the gas flow velocity above the driving block 142 is faster than the gas flow velocity below the driving block 142, and therefore, the driving block 142 is forced upward to move the guide rod 141 and the striking head 143 upward; in the absence of wind, the guide rod 141 drives the knocking head 143 to move downwards under the left and right of the return spring 144 and knock on the dust screen 134, so that the dust screen 134 vibrates to shake off the flying dust attached to the dust screen 134, and the dust screen 134 is prevented from being blocked by the flying dust.

An illumination lamp 113 is installed in the box body 11, and the illumination lamp 113 can provide illumination.

The solar panel 114 is installed on the box body 11, the storage battery 115 is arranged in the box body 11, electric energy generated by the solar panel 114 is stored in the storage battery 115, and the storage battery 115 is used for supplying power to the illuminating lamp 113 and the exhaust fan 124 so as to utilize solar power to generate power for the illuminating lamp 113 and the exhaust fan 124.

Finally, it should be noted that: the present invention is not limited to the above-described preferred embodiments, but various modifications and changes can be made by those skilled in the art, and the embodiments and features of the embodiments of the present invention can be combined with each other arbitrarily without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
