Detailed Description
For a better understanding of the present invention, the present invention is further described below with reference to specific examples and drawings.
As shown in fig. 1-5, a box-type substation comprises a rectangular base 8, wherein vertical plates in direct contact with the ground are fixedly connected to the periphery of the base 8. The right-angle binding 6 which is vertically arranged is fixedly attached to the outer end faces of the four right-angle parts in the base 8. The right-angle bordures 6 with base 8 is detachable connection, every adjacent two the laminating is fixed with dull and stereotyped bordures between the 6 bottoms of right-angle bordures, dull and stereotyped bordures with base 8 and right-angle bordures 6 for detachable connection to the equipment of this box-type substation and the going on of dismantlement work, and then for box-type substation's maintenance work convenience.
In order to simplify the connection structure of detachable connection, therefore all offer a plurality of mounting holes on right angle 6 bottom terminal surface of borduring, dull and stereotyped both ends terminal surface of borduring and the base 8 side terminal surface, right angle 6 bordure dull and stereotyped limit with base 8 passes through bolt fixed connection. The right-angle cladding 6 and the flat cladding and the base 8 thus together form a supporting structure for the installation of the side walls 2 and the top cover 1 of the fixed box-type substation.
In order to improve the convenience of assembly between the right-angle binding 6 and the base 8 and to avoid injury to staff caused by sharp corners of the right-angle binding 6, the bottom edge of the right-angle binding 6 is designed to be arc-shaped with an outward curve. Likewise, sharp corners of the panel are cut away to improve the safety of the worker during assembly.
The two right-angle surfaces of the right-angle wrapping 6 are integrally formed, namely, the two planes are bent to 90 degrees through a stamping process so as to be assembled and fixed with the base 8, so that the right-angle wrapping 6 of the structure has higher mechanical strength compared with a traditional vertical support splice plate, and the product quality of the invention can be further and obviously improved.

The top cap side is along the bottom and is through the backup pad that bolt fixed connection level was placed, the backup pad is located the top cap side is along the inboard, a plurality of first louvres 4 that are linear array evenly distributed have been seted up to the horizontal terminal surface of backup pad, a large-scale second louvre 5 or a plurality of small-size second louvres 5 that are linear array evenly distributed have all been seted up at the top of top cap 1, can show like this increase box-type substation heat dissipation route to reach the purpose of optimizing box-type substation radiating effect.
The top cap 1 fixedly connected with cover body, the cover body include cover top and with the bend ventilation sand control support of cover top through self-plugging rivet rigid coupling, cover top outside edge is through self-plugging rivet rigid coupling eaves of keeping off rain, the eaves of keeping off rain slope sets up, the eaves of keeping off rain with top cap main part slope trend is unanimous.
The curve ventilation sand control support with riser fixed connection in the top cap 1, curve ventilation sand control support includes backup pad and lower backup pad, it is as an organic whole that last backup pad and lower backup pad pass through self-plugging rivet fixed connection, go up and all offered the ventilation in backup pad and the lower backup pad and use second louvre 5, it is located to go up backup pad and lower backup pad the rain eaves is inboard, second louvre 5 in the top cap 1 is located the inboard of riser. The curve ventilation sand-proof support and the top cover 1 jointly form the slope curve.
The design makes the rainwater can flow onto the outer surface of the top cover 1 under the blocking of the vertical plate even after passing through the gap between the rain-shielding eave and the top plate and keeping air circulation. Because the top cover 1 is obliquely downwards arranged, and a certain gap exists between the bottom of the rain-shielding eave and the top cover 1, rainwater entering the inner side of the rain-shielding eave can quickly slide down from the top cover 1 at the bottom of the rain-shielding eave.
The lower end of the top cover 1 is provided with a plurality of exhaust fans 7. The exhaust fan 7 comprises a mounting seat with a rectangular mounting frame structure. In order to make the installation operation between the exhaust fan 7 and the box-type substation more convenient, the edge of the installation seat is provided with an assembly hole for assembling and connecting with the top of the box-type substation. The damping rubber gasket is arranged between the mounting seat and the top cover 1, so that the running state of the exhaust fan 7 can be more stable, and the impact of the mounting seat on the top cover 1 is obviously reduced.
The rear end of the mounting frame is fixedly connected with a plurality of supporting ribs which are bent backwards and arc-shaped through bolts, and the arc-shaped design is used for improving the supporting capacity of the supporting ribs. The supporting ribs are uniformly distributed in a circular array by taking the central line of the mounting seat as an axis, and form a bracket for assembling parts. The parts comprise a motor, a mounting shaft, fan blades and the like.
Specifically, the bracket is fixedly provided with a power supply device, namely the motor. And an output shaft of the motor is connected with the mounting shaft in a threaded manner. The outer side of the mounting shaft is fixedly connected with a plurality of streamline fan blades which are uniformly distributed at equal intervals. The structural design of the fan blades is to improve the air exhaust capacity of the fan on one hand; on the other hand, the streamline design can obviously reduce air resistance, so that the heat emission efficiency of the exhaust fan 7 is improved. In order to further expand the discharge passage of the hot air to the outside of the box-type substation, the minimum distance between two adjacent fan blades is designed to be not less than 4cm.
In addition, the mechanical strength of the exhaust fan 7 can be obviously improved by utilizing the stainless steel material to prepare the fan blades, the supporting ribs and the mounting seats, the rust resistance of the exhaust fan is effectively improved, and the service life of the exhaust fan 7 is prolonged.

Wherein, the flabellum with the collar passes through welding mode fixed connection.
In order to further improve the mechanical strength of the mounting base, the supporting rib and the fan blade, the mounting base, the supporting rib and the fan blade are designed to be manufactured by stainless steel materials. The design can also effectively improve the rust resistance of the exhaust fan 7. In order to further improve the rust resistance, the surfaces of the mounting seat, the supporting ribs and the fan blades can be coated with a high flame-retardant rust-proof paint layer. In order to make the heat in the box-type transformer station smoothly enter the second heat dissipation holes 5 through the exhaust fan 7, a slope heat dissipation channel for evacuating the excessive heat is installed at the lower end of the top cover 1 positioned at the upper end of the exhaust fan 7. The heat in the box-type transformer substation is conveyed to the first radiating holes 4 and the slope-shaped radiating channels through the exhaust fans 7, and is conveyed to the second radiating holes 5 through the slope-shaped radiating channels. The slope-shaped heat dissipation channels are formed by two top plates of the box-type transformer substation, which are symmetrically and obliquely downwards arranged from the middle to two sides, and heat dissipation gaps reserved between the two top plates.
The foregoing describes the embodiments of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by this patent.
