Detailed Description
As shown in fig. 1-7, a communication and electrical control cabinet comprises a shell 1, an air inlet hole 2 is formed in one side wall of the shell 1, a negative pressure fan 3 is arranged on the other side wall, opposite to the air inlet hole 2, of the shell 1, an air inlet end of the negative pressure fan 3 is communicated with the inside of the shell 1, a negative pressure ventilation plug is matched with the air inlet hole 2 on the shell 1 and is connected with the negative pressure fan 3 in a control manner, a heat sensor 4 is arranged in the shell 1, and the heat sensor 4 is in signal connection with the negative pressure fan 3.
In the present embodiment, the housing 1 is provided with an opening, and a cover 10 is cooperatively provided for opening the cover 10 when mounting hardware or electrical components in the housing 1, and then covering the cover 10. When the heat in the shell 1 increases, the heat sensor 4 transmits a signal to the negative pressure fan 3, the negative pressure fan 3 starts to work, so that the negative pressure ventilation plug is opened, namely the negative pressure ventilation plug is not plugged into the air inlet hole 2, the heat in the shell 1 is sucked away, at the moment, air enters the shell 1 from the air inlet hole 2, then leaves the shell 1 from the air outlet of the negative pressure fan 3, and the heat is taken out of the shell 1. When the heat is not dissipated in the casing 1, that is, when the heat dissipation is not required in the casing 1, the negative pressure fan 3 works, and at the moment, no negative pressure exists in the casing 1, so that the negative pressure ventilation plug plugs the air inlet hole 2, and dust outside the casing 1 cannot enter the casing 1. Therefore, the problem of how to prevent dust from entering the control cabinet when heat dissipation is not carried out in the control cabinet is solved.
In a preferred manner, in order to prevent foreign substances from entering the housing 1 or from outside when the negative pressure fan 3 is in operation, a filter screen 5 is provided on the outer surface of the housing 1 at a position corresponding to the air intake hole 2.
As a preferred mode, as shown in fig. 3, 4, 6 and 7, the negative pressure ventilation plug comprises a plug body 6, a spring 7 and a protrusion 8, the plug body 6 is of a cylindrical structure with one end open, a vent hole 9 is formed in the side wall of the plug body 6, two protrusions 8 are arranged on the outer circumferential wall of the plug body 6 near one end with the opening, one end of each protrusion 8, which is opposite to the opening of the plug body 6, is fixedly connected with one end of the spring 7, the axis of the spring 7 is parallel to the axis of the plug body 6, sliding grooves 11 which are matched with the two protrusions 8 are formed in the inner side wall of the air inlet hole 2, the axis of each sliding groove 11 is parallel to the axis of the spring 7, and when the protrusions 8 slide to one end of the sliding grooves 11 facing the inside of the shell 1, the vent hole 9 is completely exposed in the shell 1. After the arrangement, when no negative pressure exists in the shell 1, the plug body 6 plugs the air inlet hole 2 under the action of the spring 7, when negative pressure is generated in the shell 1, the pressure outside the shell 1 presses the plug body 6, the tensile force of the spring 7 is overcome, the plug body 6 is partially separated from the air inlet hole 2, the air vent 9 is exposed in the shell 1, air flow enters from the air inlet hole 2, then enters the shell 1 through the inside of the plug body 6 and the air vent 9, and then exits from the air outlet of the negative pressure fan 3.
As a preferred way, the two protrusions 8 are symmetrical about the geometric center of the cross section of the plug body 6. The arrangement mode ensures that the tensile force of the spring 7 borne by the plug body 6 is uniformly distributed, thereby avoiding the situation that the plug body 6 is blocked in the process of axially moving in the air inlet hole 2.
As a preferable mode, the casing 1 is in a cuboid shape, a plurality of air inlets 2 are formed in the side wall, opposite to the side wall where the negative pressure fan 3 is arranged, of the casing 1, and each air inlet 2 is provided with a negative pressure ventilation plug in a matched mode. Such a setting is convenient for installation and placement.
