A bearing plate 103 is provided on one side of the installation strip 102. A fixing cylinder 104 is fixedly installed at the bottom of the main body 1 of the distribution box. A waterproof hopper 105 is fixedly connected inside the fixing cylinder 104.

[0027] A sealing strip 201 is provided on one side of the box door 2, and a lock strip 202 is provided on one side of the box door 2.

[0028] Further explanation is needed: A sealing plate 101 is provided on one side of the main body 1 of the distribution box. The sealing plate 101 can cooperate with the sealing strip 201 inside the box door 2 to seal the box door 2 when closed, preventing rainwater from entering the interior of the main body 1 of the distribution box. A heat dissipation mechanism 3 is provided inside the main body 1 of the distribution box to facilitate heat dissipation. An air intake mechanism 4 is provided at the bottom of the main body 1 of the distribution box to facilitate the blowing of external air into the interior of the main body 1 of the distribution box. The air is blown out from the protrusions 301 on both sides of the main body 1 of the distribution box, which facilitates heat dissipation inside the main body 1 of the distribution box while preventing rainwater from entering the interior of the main body 1 of the distribution box through the protrusions 301.

[0029] Example 2

[0030] Please see Figure 2-5 The present invention provides the following technical solution:

[0031] The air intake mechanism 4 includes a fan 401, a connecting shaft 402, a transmission belt 403, a motor 404, a transmission wheel 405, an air intake screen 406, and an insect screen 407. The fan 401 is located at the bottom of the main body 1 of the distribution box. The connecting shaft 402 is fixedly connected to the top of the fan 401. The transmission belt 403 is located on the outer surface of the connecting shaft 402. The transmission wheel 405 is located on one side of the transmission belt 403. The motor 404 is located at the bottom of the transmission wheel 405. The air intake screen 406 is located inside the main body 1 of the distribution box, and the insect screen 407 is located at the bottom of the fan 401.

[0032] The heat dissipation mechanism 3 includes a protrusion 301, a heat dissipation groove 302, a protective mesh plate 303, and a fixing screw 304. The protrusion 301 is fixedly connected to one side of the main body 1 of the distribution box. The heat dissipation groove 302 is opened inside the main body 1 of the distribution box. The protective mesh plate 303 is set on one side of the heat dissipation groove 302, and a fixing screw 304 is provided on one side of the protective mesh plate 303.

[0033] The fan 401 is located inside the fixed cylinder 104 and at the bottom of the air inlet mesh 406.

[0034] The motor 404 is fixedly installed inside the main body 1 of the distribution box, and the air inlet 406 is set at the bottom of the transmission belt 403.

[0035] The insect-proof net 407 is fixedly installed inside the fixed cylinder 104 and is set on the top of the waterproof hopper 105.

[0036] The heat dissipation slot 302 is opened on one side of the protrusion 301, and the fixing screw 304 is threaded into the inside of the main body 1 of the distribution box.

[0037] Further explanation is needed: the motor 404 drives the transmission wheel 405 to rotate, and the transmission wheel 405 drives the connecting shaft 402 and the fan 401 to rotate via the transmission belt 403. The fan 401 blows the air outside the distribution box body 1 into the distribution box body 1. At this time, the fixed cylinder 104, the waterproof hopper 105 and the insect net 407 can prevent rainwater from entering the distribution box body 1 through the fan 401. At this time, the air is blown out from the protrusions 301 on both sides of the distribution box body 1. The air pressure at the protrusions 301 is greater than that of the rainwater falling outside, thus preventing rainwater from entering the interior of the protrusions 301.

[0038] Working principle: When an outdoor distribution box rainproof device is used, a sealing plate 101 is first set on one side of the distribution box body 1. The sealing plate 101 can cooperate with the sealing strip 201 inside the box door 2 to seal the box door 2 when closed, preventing rainwater from entering the interior of the distribution box body 1. A heat dissipation mechanism 3 is set inside the distribution box body 1 to facilitate heat dissipation inside the distribution box body 1. An air intake mechanism 4 is set at the bottom of the distribution box body 1 to facilitate the blowing of external air into the interior of the distribution box body 1. The air is blown out from the protrusions 301 on both sides of the distribution box body 1 to facilitate heat dissipation inside the distribution box body 1 while preventing rainwater from entering the interior of the distribution box body 1 from the protrusions 301.

[0039] When it is necessary to dissipate heat inside the main body 1 of the distribution box and prevent rainwater from entering the main body 1, the motor 404 first drives the transmission wheel 405 to rotate. The transmission wheel 405 drives the connecting shaft 402 and the fan 401 to rotate through the transmission belt 403. The fan 401 blows the air outside the main body 1 of the distribution box into the main body 1 of the distribution box. At this time, the fixed cylinder 104, the waterproof hopper 105 and the insect net 407 can prevent rainwater from entering the main body 1 of the distribution box through the fan 401. At this time, the air is blown out from the protrusions 301 on both sides of the main body 1 of the distribution box. The air pressure at the protrusions 301 is greater than the rainwater falling outside, preventing rainwater from entering the protrusions 301. This device facilitates heat dissipation inside the main body 1 of the distribution box and prevents rainwater from entering the main body 1 of the distribution box.
