Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-4, a prevent outdoor high voltage distribution cabinet of rain type, including the cabinet body 1, be equipped with louvre 2 on the lateral wall of cabinet body 1 both sides, cabinet body 1 top surface installs and rotates sleeve 3 and two spacing sliding rings 4, it is connected with cabinet body 1 to rotate sleeve 3, it has pivot 5 to rotate sleeve 3 and two spacing sliding rings 4 interior axis extensions, the equal coaxial arrangement in both ends of pivot 5 has pneumatic blade 6, pivot 5 rotates with spacing sliding ring 4 and is connected, the outer annular array of pivot 5 has polylith plectrum 7, plectrum 7 is made by elastic deformation material, be equipped with on the inner circle lateral wall of sleeve 3 with plectrum 7 assorted bead 8, connecting rod fixedly connected with baffle 9 is passed through to the upper end of sleeve 3, baffle 9 can be when the rainfall, form the protection to the switch board, avoid the rainwater to get into in the switch board.
The top surface fixed mounting of the cabinet body 1 has two spouts 10, sliding connection has stopper 11 in spout 10, stopper 11 passes through the inside wall fixed connection of elastic airbag 12 and spout 10, fixed intercommunication has one-way intake pipe and one-way blast pipe 14 on the lateral wall of elastic airbag 12, one-way blast pipe 14 extends to the internal setting of cabinet, when elastic airbag 12 was compressed, gaseous can get into the cabinet body 1 by one-way blast pipe 14 in, stopper 11's upper surface has movable rod 13 through hinge, movable rod 13's upper end is rotated with baffle 9's bottom surface and is connected.
The working principle of the embodiment is as follows: during rainfall weather, often be accompanied with the high wind, the rainwater blows down at wind-force, can descend to 1 top surface of the cabinet body and side with certain inclination, the high wind blows to wind moving blade 6 and can drive pivot 5 rotatory, stir bead 8 by plectrum 7 then, it deflects to drive rotating sleeve 3, then baffle 9 deflects certain angle towards the opposite direction that the wind blown, realize the effect of the protection direction and the scope of automatically regulated baffle 9, prevent that the rainwater that falls down at wind-force blowing from getting into the cabinet body 1 by louvre 2, promote the effect of preventing wind and rain of switch board.
In the deflection process of the baffle 9, the movable rod 13 drives the limiting block 11 to slide in the sliding groove 10, the elastic air bag 12 is compressed to the shortest state, the rotating sleeve 3 cannot rotate at the moment, the shifting piece 7 is bent and deformed under the action of friction force, the rotating shaft 5 can rotate freely relative to the rotating sleeve 3, and the pneumatic blade 6 is prevented from being broken by large thrust when wind power is too large.
When the baffle 9 deflects, the movable rod 13 drives the limiting block 11 to slide in the sliding groove 10, the elastic air bag 12 is compressed, air in the elastic air bag 12 enters the cabinet body 1 through the one-way exhaust pipe 14, air pressure in the cabinet body 1 is increased, partial air in the cabinet body 1 is discharged through the heat dissipation holes 2, opposite impact is formed between partial air and external inclined air flow and rainwater, and rainwater is further prevented from entering the cabinet body 1.
After the wind and rain stops, the elastic air bag 12 resets to push the limiting block 11 to move to the initial position, and then the baffle 9 rotates to the position right above the box body 1, so that the occupied area of the power distribution cabinet is effectively saved, and the requirements of flatness and standardization are met.
Example 2
As shown in fig. 5, the present embodiment is different from embodiment 1 in that: be equipped with strip chamber 15 in baffle 9, the arc shape setting that is middle part undercut both ends perk that makes progress of strip chamber 15, sliding connection has permanent magnetism piece 16 in strip chamber 15, it has rotor plate 17 to articulate on louvre 2's the lateral wall, rotor plate 17 is fixed with the lateral wall of the cabinet body 1 through elasticity billet 18, rotor plate 17 sets up with the lateral wall of the cabinet body 1 is perpendicular, elasticity billet 8 is under natural state, rotor plate 17 is perpendicular with the lateral wall of the cabinet body 1, avoid sheltering from heat dissipation hole 2 formation, influence its normal ventilation radiating effect, rotor plate 17 is made by magnetic material and is repelled mutually with permanent magnetism piece 16 homopolarity.
In this embodiment, when strong wind continuously blows, baffle 9 is in the deflection position all the time, and permanent magnetism piece 16 moves to bar chamber 15 lower position one end under the action of gravity to be close to with rotor plate 17's position, under the repulsion effect, promote rotor plate 17 and take place to deflect, rotor plate 17 forms the effect of sheltering from to louvre 2, has further promoted the weather proof effect of switch board.
After the wind and rain stops, elastic airbag 12 resets, promotes stopper 11 and moves to initial position, then baffle 9 rotates directly over the box 1, under the action of gravity, permanent magnetism piece 16 slides to bar chamber 15 middle part, and the repulsion effect far away from rotor plate 17 reduces promptly, then under the elastic force effect of elasticity billet 18, rotor plate 17 resumes with the lateral wall vertical state of the cabinet body 1, avoids sheltering from heat dissipation hole 2 formation, influences its normal ventilation cooling effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
