Abstract
The invention discloses an air flue with adjustable blades. The air flue with the adjustable blades is characterized by comprising two groups of blades in identical shapes; one group of blades comprises a large blade and a small blade with two sections being in trapezoid shapes and one side being opened; the large blade is arranged at the periphery of the small blade; opening directions of the large blade and the small blade are same; opening positions of the two groups of blades are oppositely arranged; the short bottom edge of the large blade is arranged at an opening of the small blade of the other group of blades. The air flue with the adjustable blades solves the problem that, in the prior art, particle gravels enter indoor rooms along with wind and hidden risks are remained for normal operation of electrical equipment inside a box, greatly reduces entering of impurities of the particle gravels through the bending arrangement on the blades due to the fact that the two groups of blades in identical shapes are spliced into an air inlet and guaranteeing clean of the indoor rooms.
Description
Technical field
The present invention relates to a kind of ventilation unit, particularly a kind of air channel fence of adjustable flabellum.
Background technology
The increasing equipment of development along with technology has higher requirement to operational environment.As in transformer station's product, because assembling is very large with the caloric value of power equipment wherein, thus being discharged by the heat in transformer station box is a requisite process, generally perforate on the casing of transformer station, and the mode that perforate is installed ventilation unit realizes.
But the device of existing ventilation is carrying out in aeration-cooling process to the power equipment in casing, and a large amount of particle sandstone can enter in transformer station box, leave hidden danger to the normal operation of the power equipment in casing thereupon.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustable protective ventilation device, while air circulation is carried out in guarantee, particle sandstone effectively can be stoped to enter, ensure that the safe operation of equipment.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of air channel fence of adjustable flabellum, it is characterized in that: comprise the identical and blade of parallel placement of two groups of shapes, one group of leaf packet contains the identical blade of two shapes, a blade is made up of a horizontal edge and a flanging, and horizontal edge is parallel, and the bending of flanging in opposite directions, and on the horizontal edge that two blades are corresponding, be provided with movable rod be connected, blade horizontal edge is connected with there being metal spring leaf between movable rod.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: leave space between described blade.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: the angle of described blade horizontal edge and horizontal direction is 10-70 degree.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: the angle of described blade flanging and horizontal edge is 20-160 degree.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: described blade is aluminum alloy material.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: described movable rod is set to vertical direction.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: described movable rod is fixed in the chute of window frame both sides.
The air channel fence of aforesaid a kind of adjustable flabellum, is characterized in that: described movable rod is duroplasts material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air channel fence of a kind of adjustable flabellum of the present invention.
Fig. 2 is the schematic diagram of air channel fence when blade is completely closed of a kind of adjustable flabellum of the present invention.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of air channel fence of adjustable flabellum, it is characterized in that: comprise the identical and blade of parallel placement of two groups of shapes, one group of leaf packet contains the identical blade 1 of two shapes, a blade is made up of a horizontal edge 2 and a flanging 3, and horizontal edge 2 is parallel, and the bending of flanging 3 in opposite directions, and on the horizontal edge 2 of two blade 1 correspondences, be provided with movable rod 4 be connected, there is metal spring leaf 5 to be connected between blade horizontal edge 2 with movable rod 4.Space is left between described blade 1.Described blade horizontal edge 2 is 10-70 degree with the angle of horizontal direction, is preferably 30 degree.Described blade flanging 3 is 20-160 degree with the angle of horizontal edge 2, is preferably 150 degree.Described blade 1 is aluminum alloy material, and skin-friction force is less, sandstone landing of being more convenient for.Described movable rod 4 is set to vertical direction.Described movable rod is fixed in the chute of window frame both sides.Described movable rod 4 is duroplasts material.
In use, before this ventilation unit is arranged on wind inlet channel grid, wind is entered before the grid of air channel first by this ventilation unit.Wind enters between two groups of blades of ventilation unit, and when striking blade flanging 3, partial particulate sandstone can be slipped to outside ventilation unit by the horizontal edge 2 because of deadweight along blade, thus achieves in the wind entering indoor air channel grid hardly with particle sandstone.
As shown in Figure 2, when indoor mechanical equipment needs maintaining or meets with pole bad weather, can, by blade 1 tight closure, outdoor impurity be stoped to enter.By the movable rod 4 be fixed in the chute of window frame both sides that slides, make the metal spring leaf 5 be fixed between blade horizontal edge 2 and movable rod 4 be squeezed and bend, the power of its deformation produced makes tight closure between blade 1, hinders entering of impurity completely.
In sum, a kind of protective ventilation device provided by the invention, effectively can stop the particle sandstone in wind to enter indoor, ensure that the safe operation of equipment.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is by appending claims and equivalent circle thereof.
