Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
Referring to fig. 1-7, the present invention provides an embodiment: the utility model provides an electric automatization cubical switchboard of frost prevention, including the cabinet body 1, and with the cabinet body 1 cabinet door 2 of being connected through hinge 3 rotation, 1 one side upper portion of the cabinet body is provided with the air inlet, 1 opposite side lower part of the cabinet body is provided with the gas outlet, the air inlet all seals and fixedly connected with shutter 4 with the gas outlet inner wall, air inlet department shutter 4 is located 1 inside one end fixedly connected with heating device 5 of the cabinet body, gas outlet department shutter 4 is located 1 inside one end fixedly connected with exhaust fan 15 of the cabinet body, the cabinet body 1 all is provided with heat preservation 10 with 2 cabinet wall insides of cabinet door, 1 interior bottom of the cabinet body is provided with temperature and humidity sensor 8, temperature and humidity sensor 8 respectively with heating device 5, 15 electric connection of exhaust fan.
Through the setting of heat preservation 10, make the heat conductivity of cubical switchboard reduce, simultaneously through the setting of temperature humidity transducer 8, make heating device 5 and exhaust fan 15 just move when the condition reaches, both avoided the inside frost phenomenon that appears of cubical switchboard, avoided the easy problem that runs off of cubical switchboard inside heat again, reduced the waste of resource.
An air outlet of the heating device 5 is fixedly connected with a first dehumidifying box 6, air inlet ends and air outlet ends of the first dehumidifying box 6 are provided with air holes, and a dehumidifying agent 16 is arranged inside the first dehumidifying box 6.
The desiccant 16 inside the first desiccant box 6 absorbs moisture so that the entering air becomes dry, avoiding the problem of moisture entering through the air inlet.
The sealing strip 9 is arranged at one end of the cabinet body 1 contacting with the cabinet door 2.
Through the setting of sealing strip 9 for the cabinet body 1 is inseparabler with the contact of cabinet door 2, thereby has avoided outside steam to get into in the cabinet by crack department.
A filter screen 14 is arranged in the shutter 4, and the filter screen 14 is made of sponge with the thickness of 1-3 cm.
Shutter 4 has avoided the rainwater to get into in the cabinet, and filter screen 14 has avoided the dust to get into the cabinet simultaneously, and the sponge also plays certain heat preservation effect simultaneously.
An air inlet of the exhaust fan 15 is fixedly connected with a second dehumidification box 7, air holes are formed in the outer wall of the second dehumidification box 7, and a dehumidification agent 16 is arranged inside the second dehumidification box 7.
The second dehumidifying box 7 prevents moisture from entering the cabinet through the air outlet when the ventilating fan 15 does not work.
The lower part of the cabinet body 1 is provided with a wire inlet 11, and the inner wall of the wire inlet 11 is sleeved with an elastic sealing ring 12.
