Abstract
The utility model relates to a shutter. The shutter comprises a window frame and a vane group arranged in the window frame, wherein the vane group is formed by arranging a plurality of vanes from top to bottom at intervals; the sections of the vanes are roughly Z-shaped; and the window frame is fixedly connected with the vanes by bolts. The shutter has the following beneficial effects that: the sections of the vanes are roughly Z-shaped, thus meeting the strength requirements of the vanes; the vanes are arranged according to a proper space, thus preventing bigger foreign matters from entering the air ducts of the equipment and improving the protection grade while ensuring maximum effective inlet air area and effective waterproofness of the shutter; and besides, the bolts are pressure-riveted on the window frame to fixedly connect the vanes with the window frame, without welding, thus avoiding the defects caused in the welding process, such as shutter deformation.
Description
Technical field
The utility model relates to a kind of shutter.
Background technology
Photovoltaic/wind power grid-connected generating technology is the important component part of renewable energy technologies development; Obtained tremendous development in recent years, the part technology has realized commercialization, however the part that still comes with some shortcomings; Particularly in high-power application of generating electricity by way of merging two or more grid systems; Because the calorific value of electric equipment is all bigger, guarantee the normal operation of power-supply device, must make the heater element efficiently radiates heat that power-supply device is inner.The shutter that uses at present; Its effective incoming air area is limited; In use need open very big air intake and can satisfy the heat radiation requirement of power-supply device, and can't be directly with carrying out effective waterproof out of doors, degree of protection is lower; So just limit the scope of application of power-supply device, can't satisfy the instructions for use of outdoor subscriber.It is fixing that outdoor shutter normally adopts the mode of blinds and shutter frame welding to be connected, and this structure can cause the shutter distortion usually, influence outward appearance, and percent defective is higher in the process.
The utility model content
The purpose of the utility model be to provide a kind of degree of protection high, can guarantee abundant air intake, good heat dissipation effect, can avoid in welding process, causing the shutter that is out of shape.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of shutter comprises window frame and is arranged on the vane group in the window frame that vane group is spaced by a plurality of blades and forms from top to bottom; It is Z-shaped that the cross sectional shape of blade roughly is, and window frame is crossed screw with blade pass and is connected.
Self-clinching stud on the described window frame, blade are strip, and its upper and lower two sections is riser, is swash plate between two risers, and the hypomere riser of blade passes through screw in the back side of window frame.
Described screw is a sunk screw.
Evenly at interval offer a plurality of strip holes from top to bottom on the described window frame, self-clinching stud between the two adjacent strip holes on the window frame framework, screw has spacing along the length direction of window frame separation successively between the epimere riser of blade and the strip hole.
Mounting filtering net between described window frame and the blade.
Described screen pack is a silk screen.
Can know by technique scheme; The cross sectional shape of blade roughly is Z-shaped in the utility model; Satisfied the requirement of strength of blade, blade is according to suitable pitch arrangement, when guaranteeing the maximum effectively incoming air area of shutter and effective waterproof; Can prevent the air channel of big foreign matter access arrangement, improve degree of protection.In addition, self-clinching stud on window frame is connected blade and window frame fixingly with screw, need not welding, can avoid the defectives such as shutter distortion that in welding process, cause.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the enlarged drawing of B part among Fig. 2;
Fig. 4 is the structural representation of window frame among Fig. 1.
The specific embodiment
A kind of shutter comprises window frame 1 and is arranged on the vane group in the window frame 1 that vane group is spaced by a plurality of blades 2 and forms from top to bottom; It is Z-shaped that the cross sectional shape of blade 2 roughly is; Window frame 1 is fixedly connected through screw 3 with blade 2, need not blade 2 is welded on the window frame 1, has avoided the shutter distortion and the higher defective of percent defective that cause because of welding; Avoid influencing the outward appearance of shutter, as shown in Figure 2.
Like Fig. 2, shown in 3, self-clinching stud 3 on the described window frame 1, blade 2 is a strip, and its upper and lower two sections is riser, is swash plate between two risers, and the hypomere riser of blade 2 is fixed in the back side of window frame 1 through screw 3, and described screw 3 is a sunk screw.Mounting filtering net 4 between described window frame 1 and the blade 2, described screen pack 4 is a silk screen, prevents the air channel of big foreign matter access arrangement, does not influence effective incoming air area when improving the equipment protection grade, guarantees the operation that whole set equipment can be safe and reliable.
Like Fig. 1,2, shown in 4; Evenly offer a plurality of strip hole 1a on the described window frame 1 from top to bottom at interval; Between the epimere riser of blade 2 and the strip hole 1a spacing is arranged, this structure can be avoided also can guaranteeing effective incoming air area on the other hand in the oblique entering shutter of rainwater on the one hand.Self-clinching stud 3 between the two adjacent strip hole 1a on described window frame 3 frameworks, screw 3 is along the length direction of window frame 3 separation successively.
