Description of the embodiments

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Examples

The utility model relates to a rain and snow proof electrical power distribution cabinet, as shown in fig. 1-3, this electrical power distribution cabinet is including being used for playing basic support and fixed action's base plate 1, base plate 1 upper portion is provided with and is used for placing the electrical component and get the cabinet body, because the electrical component of the internal portion of cabinet can produce more heat at the during operation, if not in time carry out effective heat dissipation, the high temperature overload of electrical component easily causes to cause the condition of shut down or spontaneous combustion, consequently, the most economical mode just is provided with ventilation channel 3 in the both sides of the cabinet body, ventilate the heat dissipation with the help of natural wind, ventilation channel 3 is generally for seting up the mesh hole in cabinet body upper portion, however this kind of ventilation channel 3 is low in production cost, but in the sleet weather, the rain and snow is the same easily to get into the internal portion of cabinet, thereby corrode inside electrical component, make electrical component appear easily corrode, fault conditions such as bad contact.

Therefore, through having set up the protection subassembly that can shelter from rain and snow in the internal position of cabinet that is close to ventilation channel 3, not hinder ventilation channel 3 again and dispel the heat for the switch board is no matter with normal weather or under the rain and snow weather, can not receive the erosion of rain and snow, keeps normal effectual free heat dissipation operation.

In order to prevent rain and snow from entering the cabinet body along the top of the cabinet body, the top of the cabinet body is additionally provided with the cover plate 5 with the opening facing downwards and larger than the size of the cabinet body, so that the rain and snow falling on the upper part of the cover plate 5 can only slide to the ground along the edge of the cover plate 5 and cannot enter the cabinet body.

The number of the ventilation channels 3 is 2, and the ventilation channels are symmetrically arranged at two sides of the cabinet body, so that an efficient circulation mode of air left-in, right-out, right-in and left-out is realized.

And a flow blocking plate 4 for preventing water vapor (such as dew) on the surface of the cabinet body from flowing into the ventilation channel 3 along the surface of the cabinet body can be additionally arranged above the ventilation channel 3, and the ventilation channel 3 is in an open state, so that dew enters the interior of the cabinet body, and electric elements are corroded.

The protection component is a shielding plate fixed inside the cabinet body and close to the ventilation channel 3, the shielding plate is divided into an upper shielding plate 6 and a lower shielding plate 7, a first gap for natural wind to pass through is reserved between the upper shielding plate 6 and the inner wall surface of the cabinet body (i.e. the wall surface on one side of the ventilation channel 3), a second gap for natural wind to pass through is reserved between the lower shielding plate 7 and the upper shielding plate 6, and the first gap and the second gap form a separation chamber 10 for natural wind to pass through, and rain and snow fall down based on self gravity.

In order to realize the effective separation between rain and snow and natural wind, the length dimension of upper shielding plate 6 is unanimous with the length dimension of lower shielding plate 7, upper shielding plate 6 is fixed in the upper half of the cabinet body, lower shielding plate 7 is fixed in the lower half of the cabinet body, the length dimension of upper shielding plate 6 and lower shielding plate 7 is 2/3 ~ 4/5 of cabinet body height dimension, under the general circumstances (wind force is less than 4 grades for a long time), adopt 2/3 size can, overlength upper shielding plate 6 and lower shielding plate 7 size can make natural wind lack sufficient wind pressure support, can not pass separation cavity 10 smoothly, and the rain and snow can strike on the outer wall surface of upper shielding plate 6 after entering the cabinet body through ventilation channel 3, then fall down along upper shielding plate 6 under the effect of self gravity to drop in the bottom of lower shielding plate 7, and in order to the rain and snow is not detained in the cabinet body inside, consequently set up in the bottom of lower shielding plate 7 and set up the drain hole 2 that is used for discharging the rain and snow in cabinet body upper portion, make rain and snow fall to the bottom 7 bottom and leave the cabinet body 2 and prevent that the heat from leaving the cabinet body and leaving the bottom of the cabinet body 2 and leaving the bottom of the cabinet body and leaving the inner part of the body through the drain hole and the inner part of the body 1 and leading to the heat to the noise to be eroded from the other end of the inner part of the protection component.

Examples

In this embodiment, as shown in fig. 4-8, further description is made of example 1, in order to further improve the protection effect of the protection component, so as to avoid that in some areas with larger wind force, rain and snow fall and pass through the separation chamber 10 along with natural wind, so that the rain and snow enter the cabinet, therefore, a ventilation valve 9 is additionally arranged on one side (inner wall of the cabinet) of the ventilation pipeline, when the wind force is larger (the wind force is larger than 4 levels), the ventilation valve 9 is passively closed under the action of wind pressure, so that the natural wind cannot enter the cabinet, the closed state of the interior of the cabinet is maintained, so as to protect the electrical element from being corroded by rain and snow, and when the wind force is reduced (the wind force is smaller than 4 levels), the ventilation valve 9 is in an open state after the wind pressure is reduced, so that the natural wind can smoothly enter the interior of the cabinet after the separation chamber 10 is separated from the rain and snow, heat of the electrical element is taken away, and normal operation of the electrical element is ensured.

The ventilation valve 9 is composed of a valve body 12 fixed at the upper part of the cabinet body and a valve core 11 capable of sliding back and forth from the inside of the valve body 12 under the action of wind pressure to open and close the ventilation channel 3, when the wind pressure is reduced, in order to realize the smooth reset of the valve core 11, a spring 13 capable of providing elastic force is additionally arranged between the valve body 12 and the valve core 11.

It will be understood that the present application has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the application. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the application without departing from the spirit and scope thereof.
