Detailed Description
To make the objects, features and advantages of the present invention more comprehensible, please refer to the accompanying drawings. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limitation of the implementation of the present invention, so that the present invention does not have the essential significance in the technology, and any modification of the structure, change of the ratio relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the function and the achievable purpose of the present invention.
Examples
An electrical equipment guard box include shell 1, dust screen 2, fan 3 and control assembly 4, control assembly 4 includes temperature sensor 41, controller 42, temperature sensor 41 set up in top in the shell 1, controller 42 close on set up in temperature sensor 41, controller 42 connects respectively temperature sensor 41 and fan 3.
The temperature sensor 41 is used for transmitting the temperature in the casing 1 to the controller 42 in real time, and the controller 42 controls the start, stop and rotation speed of the fan 3 according to the temperature data. When the temperature rises to a preset threshold value, the controller 42 controls the fans 3 to be turned on, the two fans 3 which are oppositely arranged run in the same direction, air is sucked from one fan 3, air in the box 11 is taken away, and then air is blown out from the other fan 3. When the output value of the temperature sensor 41 exceeds the threshold value, the rotating speed of the fan 3 is increased to ensure heat dissipation, and the controller 42 controls the fan 3 to operate in a reversing mode in a timed mode.
The housing 1 comprises a box body 11 and a top cover 12, wherein the top cover 12 is fixedly connected with the top of the box body 11. A first hole 111 is formed in a side surface of the box body 11, and the box body 11 further includes a hinge 110, and the hinge 110 rotatably covers the first hole 111. Two faces of the box body 11 adjacent to the first hole 111 are provided with two second holes 112 oppositely.
The second holes 112 are covered with the detachable dustproof net 2, the mesh diameter of the dustproof net 2 is 0.5mm, impurities such as broken stone and debris in a mine can be filtered, only part of tiny dust enters the box body 11, and the influence of the dust is reduced to the minimum.
The second hole 112 is located at the upper portion of the box 11, since the electrical components in the box 11 can generate heat by itself, the air around the electrical components can be heated and raised, the heated air can be raised, the position of the second hole 112 can determine the height of the heat dissipation air duct, and the second hole 112 located at the upper portion of the box 11 can take out the hot air, which is more effective than when the position is low.
The fan 3 can rotate in two directions, and some dust can be adsorbed on the surface and meshes of the dustproof net 2 after the fan 3 operates for a period of time, so that the adsorbed dust can be blown out reversely after the fan 3 operates in a reversing mode at regular time, the replacement period of the dustproof net 2 is prolonged, and the maintenance frequency is reduced.
The box 11 with hinge 110 junction is equipped with the sealing washer, not only can prevent that the dust from getting into from the gap of box 11 with hinge 110, can guarantee moreover that the radiating air duct effect in the box 11 promotes, further guarantees radiating efficiency.
