In view of this, the utility model provides an intelligent exhaust and dehumidification device for the ring network cabinet. The preferred embodiments of the utility model will be described below in conjunction with the accompanying drawings.

Referring to Figure 1, an intelligent exhaust and dehumidification device for a ring network cabinet includes: a temperature and humidity controller 1, a battery 2, an exhaust fan 3 and a solar charging module 4; the temperature and humidity controller 1 and the battery 2 are installed in the ring network cabinet, The exhaust fan 3 is installed on the side wall of the ring network cabinet, the solar charging module 4 is installed on the top of the ring network cabinet, the temperature and humidity controller 1 is connected to the exhaust fan 3, and both the temperature and humidity controller 1 and the exhaust fan 3 are connected to the battery 2. The solar charging module 4 charges the storage battery 2; the solar charging module 4 includes: a solar panel 401, a bracket 402, a rotating mechanism 403 and a support seat 404; the solar panel 401 is installed on the I-shaped bracket 402, and the middle part of the bracket 402 The supporting base 404 is connected through the rotating mechanism 403 . Install a dustproof net cover on the outer wall of the ring main cabinet body at the air inlet of exhaust fan 3.

Referring to Fig. 3, wherein, the rotating mechanism 403 includes: a Kuang-shaped turret 4031, a U-shaped fixed frame 4032, a pin shaft 4033 and a limit slider 4034; In the middle part of frame 402, two side plates of Kuang type turret 4031 and two side plates of U-shaped fixed frame 4032 are connected by pin 4033, and two side plates of Kuang type turret 4031 are provided with a pair of limit chute 4035, The limit chute 4035 is an arc-shaped hole, with the pin hole 4036 as the center and the distance from the limit slide block 4034 to the pin hole 4036 as a radius. A limit slide block 4034 is fixed, and the limit slide block 4034 slides in the limit chute 4035 . The central angle of the limiting chute 4035 is 120 degrees.

The support seat 404 includes: a rotating shaft 4041, a shaft sleeve 4042, a set bolt 4043 and a fixing seat 4044; the upper end of the rotating shaft 4041 is vertically fixed on the bottom plate connecting the two side plates of the U-shaped fixed frame 4032, and the lower part is inserted into the shaft sleeve 4042, and the shaft sleeve 4042 The bottom end is vertically fixed on the rectangular fixing seat 4044 , and the set screw is screwed in from the through hole outside the shaft sleeve 4042 and pressed against the surface of the shaft sleeve 4042 . Specifically, when the humidity is too high, there is serious condensation on the top of the ring network cabinet, and the water drops keep falling on the secondary terminal, causing the signal circuit to be short-circuited, the signal to be sent by mistake, and the reliability of the equipment operation to be reduced. More seriously, water droplets on the current circuit or power circuit are likely to cause a short circuit and fire in the equipment, which poses a serious hidden danger. With the advancement of technology, the use of signal acquisition technology and the use of electromagnetic relay devices, when the humidity sensing device senses that the humidity in the cabinet exceeds the set threshold, the switch is automatically turned on, the dehumidification device starts to work, and when the expected value is reached, it is automatically turned off.

Specifically, two A-level 50W solar panels 401 are used as the charging module to charge the battery 2, and the model is WHD48-11 temperature and humidity controller 1, which can monitor the temperature and humidity in the environment and automatically open according to the set opening conditions. For example: set the open humidity condition to 55% RH, in order to make the monitoring system operate normally, it can set the humidity monitoring hysteresis, the setting range is 0-20, if it is set to 10, the controller will monitor the ambient humidity Turn off the switch when the RH is less than 45%, and use the humidity monitoring and control system to form the controller of the strong exhaust intelligent dehumidification device of the ring network cabinet.
