Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is that the vent equipment in the prior art is fixed, has a certain inclination angle, and cannot be adjusted. After the equipment has been in operation for a long time, the window is easy to accumulate dust and is difficult to clean, especially in spring windy and summer rainy days. , Dust and small sundries, insects, rainwater, etc. are easy to enter the power distribution room from the vent, causing the power distribution room to be dirty. The existing air vent is designed to be opened manually. Discharge in time, affecting the time and efficiency of accident handling

Embodiment 1

[0031] refer to Figure 1~4 , the present embodiment provides an adjustable ventilation device, including a ventilation assembly 100 and an adjustment assembly 200, wherein the ventilation assembly 100 includes a mounting frame 101, a rotating member 102 coaxially arranged with the mounting frame 101, and uniformly distributed along the circumference of the rotating member 102 Several rotating rods 103 inserted into the rotating member 102 at one end, and several blades 104, the blades 104 are installed on the rotating rod 103, the blades 104 are fan-shaped, and when several blades 104 are located on the same plane, they form a complete body with the rotating member 102. The interior of the rotating part 102 forms an accommodating space A penetrating in the axial direction; the installation frame 101 is a circular frame for accommodating the ventilation assembly 100 and the adjustment assembly 200, and the installation frame 101 is fixed on the wall of the high-voltage power di...

Embodiment 2

[0035] refer to Figure 1-7 , is the second embodiment of the present invention, this embodiment is based on the previous embodiment, and is different from the previous embodiment: in embodiment 1, when the blade 104 is adjusted to a suitable angle, it should be fixed at this angle .

[0036] Specifically, the rotating member 102 is provided with the same number of rotating holes 102a as the rotating rod 103 along the circumference, preferably, a bearing is arranged between the rotating rod 103 and the rotating holes 102a; Fixed ring 105, one end of rotating rod 103 is connected with fixed ring 105, and the other end of rotating rod 103 passes through rotating hole 102a and is connected with fork 201, and fixed ring 105 is coaxially arranged with rotating member 102, and rotates simultaneously, mainly For supporting the blade 104, the rotating rod 103 is also positioned on the radial direction of the fixed ring 105, the fixed ring 105 is provided with holes coaxial with the r...

Abstract

The invention discloses an adjustable ventilation device which comprises: a ventilation assembly, wherein the ventilation assembly comprises a mounting frame, a rotating piece, a plurality of rotatingrods and a plurality of blades, the blades are mounted on the rotating rods, the blades are fan-shaped, and the blades and the rotating piece jointly form a complete circle when the blades are located on the same plane; and an adjusting assembly which comprises a swing rod perpendicularly connected with one end of the rotating rod, a ball arranged on the swing rod in a sleeving mode and a rotating disc, wherein the rotating disc is coaxial with the rotating piece and provided with a cylindrical groove in the radial direction, the diameter of the cylindrical groove is consistent with the diameter of the ball and larger than the thickness of the rotating disc, and the ball is provided with a sliding hole consistent with the diameter of the swing rod. The ventilation assembly is arranged onthe wall of the high-voltage distribution room of the transformer substation, a ventilation opening is arranged to be in a closed state when not used, the high-voltage room is well sealed, equipment is prevented from being affected with damp and accumulating dirt, and meanwhile when ventilation is needed, the ventilation amount of the ventilation assembly can be adjusted according to the temperature and humidity in the distribution room and whether smoke exists in the room or not.

Description

technical field [0001] The invention relates to the field of ventilation for power distribution rooms, in particular to an adjustable ventilation device. Background technique [0002] At present, the vents of some high-voltage power distribution rooms in some substations are designed with louver windows, which are fixed and inclined, and no other moisture-proof and dust-proof measures are installed outside. This type of vent has the following disadvantages: [0003] The equipment is fixed and has a certain inclination angle, which cannot be adjusted. Guizhou is a mountainous terrain, and the humidity is relatively high. In addition, at least 6-8 ordinary ventilation openings and 4 ventilation device ventilation openings are installed in the general power distribution room, which increases distribution. Humidity in the electrical room; after the equipment has been in operation for a long time, the window is prone to dust accumulation and is not easy to clean, especially in st...
