Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
With reference to shown in Fig. 2, according to the sunshade of a kind of preferred embodiment of the utility model, comprise the installing rack 1 be fixed on installation foundation and the multilayer sunbreaker 2 be installed on this installing rack 1, wherein, described installing rack 1 has length direction L, width W and short transverse H, described multilayer sunbreaker 2 is intervally installed on described short transverse H and the outside along described width W to described installing rack 1 extends, and blocks to be formed the same area at Different periods.
In the utility model, change original individual layer sunbreaker into multilayer sunbreaker 2, thus ensureing to block the same area formation at Different periods, and make air-flow by the interstitial flow between multilayer sunbreaker 2, effectively improve the wind loading rating of sunshade.For the sunshade for blocking rectifier transformer 3 shown in Fig. 1 and Fig. 2, blocked in Fig. 1 by individual layer sunbreaker 2, its expanded width D reaches 5.3m, not only installs difficulty, is also easily damaged by wind; Blocked by double-layered sunshade plate 21,22 in Fig. 2, wherein sunbreaker 21 expanded width D1 is 1.3m for the first time, and the expanded width D2 of second layer sunbreaker 22 is 2.3m, and capability of anti-wind is effectively promoted.
In this concept, multiple choices can be carried out to the concrete structure of above-mentioned sunshade in this area.Wherein, installing rack 1 is fixed on installation foundation, this installation foundation can be ground, electrostatic precipitator top etc. arbitrarily can the structure of fixing and mounting bracket 1 or place.Installing rack 1 can be formed as the arbitrary structures can installing multilayer sunbreaker 2, such as body of wall, steelframe etc., and the noun of locality such as " length direction L " used herein and " width W " is only in order to illustrate the utility model easily, and be not to the utmost only confined to installing rack 1 is greater than the size of width W situation in the size of length direction L, the size of width W also can be made as required to be more than or equal to the size of its length direction L.In the embodiment shown in Figure 2, length direction L is of a size of 25m, and width W is of a size of 5m, and short transverse H is of a size of 7.8m.
The utility model can design the number of plies of above-mentioned multilayer sunbreaker 2 according to actual needs, as a kind of simple and practical embodiment, described multilayer sunbreaker 2 can be two-layer, be respectively the first floor sunbreaker 21 being arranged at described installing rack 1 top and the second layer sunbreaker 22 be arranged at below described first sunbreaker 21, wherein, on the cross section perpendicular to described length direction, described first floor sunbreaker 21 is formed as having " people " shaped sections structure, and described second layer sunbreaker 22 is formed as having "eight" shape cross section structure.
In this case, because when morning and dusk, the liftoff horizontal line of the sun is comparatively near, the second layer sunbreaker 22 being in lower position keeps the sun off, and avoids being directed on the object (as rectifier transformer 3) in occlusion area; When noon, along with the sun rises gradually from ground line, second layer sunbreaker 22 cannot block object, and first floor sunbreaker 21 forms shade in object region, thus forms round-the-clock protection to object.
Just as described above, the sunshade that the utility model provides while guarantee prevents direct sunlight to object, also should be able to should have suitable capability of anti-wind.According to long-term practical experience, in the sunshade of the utility model preferred embodiment, the difference in height between described first floor sunbreaker 21 and described second layer sunbreaker 22 is 3.5m ~ 4.5m, passes through with applicable air-flow.The area of each piece of described multilayer sunbreaker 2 is preferably 30m
2~ 60m
2, thus stronger air-flow can be born, be unlikely to damage under wind-force effect.
In sunshade according to the utility model comparatively preferred embodiment, described installing rack 1 for being fixedly connected with the steelframe of (such as being connected by welding or bolt) by many Guan Liang, can be formed with the hollow space extended along described length direction between described many Guan Liang.This installing rack is easy to use, can use in the environment of various rather harsh.Further, multilayer sunbreaker 2 can be arranged on steelframe by the brace summer be welded on Guan Liang.In addition, the hollow space between Guan Liang can be used in placing the object (as rectifier transformer 3) needing to prevent direct sunlight, or, functional part can also be set in this hollow space, such as derricking gear.Particularly, can arrange the guide rail along described length direction movement on described installing rack 1, derricking gear can move on the guideway, for the also carry an object of lifting in described hollow space.
Putting position and the angle of above-mentioned sunshade can be arranged according to actual needs, for the feature that the sun " rises in east and drop in west ", preferably installing rack 1 is arranged as and makes described length direction L be positioned in North and South direction, so that larger region can be blocked.
On the basis of above-mentioned sunshade, the utility model also provides a kind of electric dust removing system, the described sunshade comprising electrostatic precipitator, be positioned at the rectifier transformer 3 at the top of this electrostatic precipitator and provide according to the utility model, this sunshade is fixedly installed in the top of described electrostatic precipitator to avoid sunlight direct irradiation on described rectifier transformer 3.In this electric dust removing system, the top of electrostatic precipitator is namely for the installation foundation of fixing and mounting bracket 1.
Usually, described electric dust removing system comprises the multiple stage rectifier transformer 3 that L along its length arranges.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.In order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
