It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention. In addition, in the following structures, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the concepts of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate an orientation or a positional relationship based on the orientation or the positional relationship shown in the drawings, and are merely for convenience of description of the present invention and simplification of the description. Rather than indicating or implying that the apparatus or elements herein referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The anti-condensation box type switching station shown in fig. 1 to 6 comprises a switching station body 1, and a supporting mechanism 100 is arranged at a bottom frame 10 of the switching station.
The support mechanism 100 includes a first base plate 110 in contact with the installation interface, and a second base plate 130 is installed on the upper portion of the first base plate 110 through a plurality of support channels 120. The three are formed by welding, and the surface is sprayed with paint. The first base plate 110 serves as a bearing layer to secure the lifting strength. The supporting channel steel 120 adopts a uniformly stressed arrangement mode for supporting the superstructure.
A plurality of first ventilation parts 140 are provided along the outer circumference of the supporting space formed between the first base plate 110, the supporting channel steel 120 and the second base plate 130, and a mesh plate structure 141 is provided at the ventilation place of the first ventilation parts 140; the width of the first ventilation part 140 is greater than the width of the support channel 120.
Through the screen plate structure 141 of the protection level, compared with a conventional single-groove steel chassis with round holes for ventilation, the ventilation surface is greatly improved, air convection can be achieved, and water vapor in a cable well can be rapidly emitted.
The second base plate 130 mainly plays a role of supporting an internal arrangement, a second ventilation part (not shown in the drawing) is provided on the second base plate 130, and an internal switching device (not shown in the drawing) is provided on an upper portion of the second base plate 130.
With emphasis on fig. 1 and 2, a plurality of doors 150 are provided in the space at the upper edges of the side frames 20 and the second bottom plate 130 of the opening/closing station body 1, and third ventilation portions 151 are provided at the lower portions of the plurality of doors 150. The third ventilation part 151 may also be provided with a mesh plate or a structure using a plurality of ventilation grooves.
With emphasis on fig. 3 and 4, a sleeve 160 is arranged at the cable access position 131 on the second bottom plate 130, a sealing plug 161 is arranged in the sleeve 160, the inner diameter of the sealing plug 161 can be adjusted according to the cable diameter when the cable is installed on site, a certain compression amount is provided, and the cable access position 131 and the cable can be in seamless butt joint after the installation is completed. The waterproof membrane structure 170 is arranged at the pressure release hole 132 of the switching station, and the waterproof membrane structure also has the functions of moisture resistance and explosion resistance. Compared with the conventional bottom plate hole digging and cable well penetrating mode, the two improvements can enable moisture in the cable well isolated by the box type switching station to be more thorough.
The roof hanger plate 30 of the opening and closing station 1 is provided with a diagonal roof structure, and is provided with a first ventilation opening 31, an inclined cover plate structure 180 is provided on the upper portion of the roof hanger plate 30 of the opening and closing station 1, and an inclined air duct 190 (the arrow in the figure is the direction of the wind) is formed between the roof hanger plate 30 and the cover plate structure 180.
The air duct 190 connects the first vent 31 with the environment outside the tank; so that the wall built-up dew can be timely discharged to the second air vent 181 of the cover plate structure 180 through the inclined direction in the air duct 190 after being formed. For dust-proof and simultaneous ventilation, a mesh plate structure is provided at the second ventilation opening 181 of the cover plate structure 180.
In order to further increase ventilation efficiency, an air circulation system including an air extraction fan 210 and an air supply fan 220 is provided at the second ventilation opening 181 of the hood structure 180.
The air in the box type switching station 1 is exchanged and circulated with the outside environment air through the air duct 190 by the air extraction fan 210 and the air supply fan 220, so that the temperature and humidity balance is achieved.
Compared with the conventional flat suspended ceiling without a circulating channel, the method is more efficient and reasonable, and the phenomenon that the wall built-up condensation drops into the switch equipment caused by the temperature difference between the inside and outside of the box-type switching station is avoided to the maximum extent.
The foregoing has shown and described the basic principles and features of the invention and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, which have been described in the foregoing embodiments and description merely illustrates the principles of the invention, and that various changes and modifications may be effected therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents.
