[0003] However, in the prior art, in order to increase the service life of existing communication equipment installed outdoors, it is usually necessary to install protective equipment to prevent dust and rain from damaging the communication equipment. However, in order to have good dustproof and waterproof functions at the same time, most of the protective equipment adopts a closed design, which makes it difficult for the communication equipment to dissipate heat and cool down after running for a long time, which can easily cause damage to the communication equipment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1-4As shown, the utility model provides a technical solution: a dustproof and waterproof protective box for communication equipment, including a metal outer box 1 for communication equipment, both sides of the inner surface of the metal outer box 1 for communication equipment are fixed with metal heat-conducting brackets 2, the metal heat-conducting brackets 2 are used to place communication equipment, because the metal heat-conducting brackets 2 are in close contact with the communication equipment and are made of metal, it is convenient to conduct the heat emitted by the communication equipment to the metal outer box 1 of the communication equipment, so as to facilitate heat dissipation, and a heat dissipation air pump 3 is fixed on the top of the inner surface of the metal outer box 1 of the communication equipment, and the output end and the input end of the heat dissipation air pump 3 are respectively An air blowing pipe 4 and an air extraction pipe 5 are fixed, and the air extraction pipe 5 is fixedly connected to the metal outer box 1 of the communication equipment. The communication equipment placed on the metal heat-conducting bracket 2 is cooled by blowing air through the cooperation of the heat dissipation air pump 3, the air blowing pipe 4 and the air extraction pipe 5. A small motor 7 is fixed to the inner side of the metal outer box 1 of the communication equipment, and a movable shaft 8 is fixed to the output end of the small motor 7. The movable shaft 8 is connected to the metal outer box 1 of the communication equipment. A mounting frame 9 is fixed to the outer surface of the movable shaft 8, and a dustproof net 10 is fixed to the surface of the mounting frame 9. When it is not raining, the dustproof net 10 blocks the opening on one side of the air extraction pipe 5 and It cooperates with the metal outer box 1 of the communication equipment to effectively isolate the external dust from contacting the communication equipment. When it rains, the small motor 7 is controlled by the control box 16 to start, so that the movable shaft 8 drives the installation frame 9 to rotate 180 degrees, so that the dustproof net 10 can be washed by rainwater and the dust accumulated on it can be cleaned. An air outlet 11 is provided at the bottom of the metal outer box 1 of the communication equipment. When the communication equipment is cooled by blowing, the hot air is blown out from the air outlet 11, and an active groove is provided at the air outlet 11 in the metal outer box 1 of the communication equipment. A sealing member 13 is rotated in the active groove. The inner surface of the metal outer box 1 of the communication equipment A stepper motor 12 is fixed to the bottom of the surface, and the output shaft of the stepper motor 12 is fixedly connected to the blocking piece 13. The stepper motor 12 is used to control the rotational displacement of the blocking piece 13. The blocking piece 13 blocks the air outlet 11. A raindrop sensor 14 is fixed to the top of the outer surface of the metal outer box 1 of the communication equipment. The raindrop sensor 14 detects whether it is raining outdoors. A control box 16 is fixed to one side of the metal outer box 1 of the communication equipment. The control box 16 is electrically connected to the raindrop sensor 14, the stepper motor 12, the small motor 7 and the heat dissipation air pump 3 to facilitate the control of their switches.

[0022] Example 2

[0023] like Figure 1-4As shown, a hollow limiting plate 6 is fixed on the surface of the metal outer box 1 of the communication equipment near one end of the exhaust pipe 5. The hollow limiting plate 6 serves to limit one end of the exhaust pipe 5 and improve its installation stability. After the mounting frame 9 is rotated and displaced, it is convenient to fit closely with the outer edge of the hollow limiting plate 6 to avoid direct contact between the dustproof net 10 and the exhaust pipe 5, and reduce the situation where the dustproof net 10 is pierced by the exhaust pipe 5. The size of the air outlet 11 and the blocking member 13 are adapted to each other, which ensures the tightness of the blocking member 13 on the air outlet 11 and reduces the gap between them. The outer surface of the metal outer box 1 of the communication equipment is located at the position of the raindrop sensor 14 and is fixedly connected with a transparent protective shell 15. The transparent protective shell 15 protects the raindrop sensor 14. Since it is transparent, it does not hinder the detection work of the raindrop sensor 14. The back of the metal outer box 1 of the communication equipment is fixedly connected with a heat sink 17. The setting of the heat sink 17 increases the efficiency of the metal outer box 1 of the communication equipment in dissipating heat outward.

[0024] Working principle:

[0025] like Figure 1-4 As shown, in an outdoor sunny weather environment, the heat dissipation air pump 3 is in an open state, so that the exhaust pipe 5 draws air from the outside. At this time, the dustproof net 10 is at the lower side of one end of the exhaust pipe 5 to prevent the exhaust pipe 5 from sucking dust into the metal outer box 1 of the communication equipment. After the exhaust pipe 5 is exhausted, the blowing pipe 4 blows air to dissipate the communication equipment on the metal thermal conductive bracket 2, and finally the hot air is dissipated outward from the unblocked air outlet 11, ensuring good heat dissipation for the communication equipment on sunny days while taking into account the dustproof effect.

[0026] When it is raining outdoors, the raindrop sensor 14 in the transparent protective shell 15 will detect the rain outside and transmit this information to the control box 16. After receiving and analyzing the information, the control box 16 will turn off the heat dissipation air pump 3 and control the stepper motor 12 to start, so that it controls the blocking member 13 to rotate to block the air outlet 11. At this time, the small motor 7 will also be controlled to start, so that the installation frame 9 carrying the dustproof net 10 can rotate 180 degrees, so that the dustproof net 10 can be washed and cleaned by rainwater. At this time, the heat emitted by the communication equipment is mainly conducted to the metal outer box 1 of the communication equipment with the help of the metal thermal conductive bracket 2, and then the metal outer box 1 of the communication equipment is quickly cooled by rainwater. At the same time, the heat sink 17 also helps to speed up the heat dissipation to ensure the heat dissipation effect. At this time, the whole device is also in a relatively closed state, ensuring a good waterproof effect.
