Description
Technical Field
[0001] This utility model belongs to the field of louver technology, and more specifically, it relates to an outward-opening, anti-entry steel plate louver. Background Technology
[0002] Louvers, as a core component for equipment ventilation and heat dissipation, are widely used in outdoor equipment such as new energy wind turbine cabinets, energy storage cabinets, and containers. However, existing louvers face the following technical bottlenecks in complex outdoor environments:
[0003] 1. Insufficient protective performance: When ventilation is turned on, it cannot effectively prevent personnel's hands, small animals (such as rodents) or foreign objects from entering the equipment, resulting in the risk of electric shock, biological gnawing on cables or mechanical damage, and prominent safety hazards in operation and maintenance.
[0004] Second, severe sand and dust intrusion: Traditional louvers lack efficient filtration structures, allowing sand and dust and flying insects to easily enter the equipment through the ventilation ducts, accumulating on the surface of electrical components, causing short circuits, corrosion, and reduced heat dissipation efficiency. According to statistics, sand and dust intrusion leads to a failure rate of about 40% for new energy equipment.
[0005] III. Waterproofing and Maintenance Defects: Ordinary louver blades have poor sealing performance, and rainwater can easily seep into the cabinet through the gaps between the blades, accelerating the corrosion of metal parts. In addition, the filter screen is mostly fixed with bolts, and replacement requires the entire louver to be disassembled, which is time-consuming and affects the continuous operation of the equipment.

[0043] This utility model provides an outward-opening, anti-entry steel plate louver. Please refer to [link / reference]. Figures 1 to 9As shown, the device includes a louver frame 100, a waterproof steel louver 200, an outward-opening louver rod 300, an anti-entry net 400, a high-ventilation-capacity cotton-filled filter screen 500, and a waterproof sealing strip 600. The louver frame 100 is fixedly installed on the equipment. Outward-opening louver rotating shafts 110 are provided at the bottom of both the left and right sides of the inner wall of the louver frame 100. The louver frame 100 is rotatably connected to the waterproof steel louver 200 via a pair of outward-opening louver rotating shafts 110. One end of the outward-opening louver rod 300... The other end of the outward-opening louver rod 300 is connected to the louver frame 100 and the waterproof steel louver 200. The anti-entry net 400 is fixedly connected to the center of the louver frame 100. Several latches 700 are provided on the inner side of the waterproof steel louver 200. The high-ventilation cotton-filled filter mesh 500 is fixed to the waterproof steel louver 200 by several latches 700. The waterproof sealing strip 600 is provided between the louver frame 100 and the waterproof steel louver 200.
[0044] It should be noted that the anti-entry net 400, fixed at the center of the louver frame 100, can prevent personnel's hands or small animals from entering the new energy equipment (wind turbine cabinet / energy storage cabinet / container) when the louvers are open, thus avoiding electric shock or equipment damage. The high-volume cotton-filled filter screen 500 is fixed by the locking buckle 700 and works with the waterproof steel plate louvers 200 to clamp the filter cotton, achieving efficient filtration of sand and dust while ensuring ventilation needs. The waterproof sealing strip 600 is set between the louver frame 100 and the waterproof steel plate louvers 200 to prevent rainwater from seeping into the cabinet and corroding the equipment. In addition, the outward opening is achieved by the outward opening louver rotation shaft 110 and the outward opening louver pull rod 300, saving space inside the cabinet, which is especially suitable for compact equipment layouts.
[0045] The waterproof steel plate louver 200 includes a waterproof steel plate window frame 210 and waterproof blades 220. The waterproof steel plate window frame 210 is constructed of bent steel plates to adapt to the vibration of wind power and energy storage equipment transportation. The waterproof steel plate window frame 210 is rectangular and annular. Several waterproof blades 220 are fixedly installed inside the waterproof steel plate window frame 210. The several waterproof blades 220 are arranged in the vertical direction, and a ventilation channel is formed between two adjacent waterproof blades 220.

The high ventilation volume cotton-filled filter screen 500 is fixed by the bottom hinge 800 and multiple latches 700. After unlocking, the filter cotton can be flipped over and replaced without disassembling the entire window.
[0047] Several of the aforementioned latches 700 are disposed on the inner contour of the inner side of the waterproof steel plate window frame 210;
[0048] refer to Figure 5 As shown, the cross-section of the waterproof blade 220 is "S" shaped, and two adjacent waterproof blades 220 are connected end to end. Several S-shaped waterproof blades 220 form an overlapping structure of multiple water-blocking barriers. The inclined ventilation channel formed by adjacent waterproof blades 220 guides rainwater out and prevents water leakage.

The rhomboid or hexagonal mesh openings combine high structural strength with ventilation efficiency, effectively blocking foreign objects (such as tools or animal limbs) from entering. Several connecting holes 420 and connecting notches 430 are provided at the outer edge of the entry barrier net 400. The connecting holes 420 and notches at the edge of the entry barrier net 400 enhance the assembly firmness and resist strong wind loads.
[0052] The outward-opening louver pull rod 300 includes a first connecting rod 310 and a second connecting rod 320. The first connecting rod 310 and the second connecting rod 320 are rotatably connected. The first connecting rod 310 is rotatably connected to the louver frame 100, and the second connecting rod 320 is rotatably connected to the waterproof steel plate louver 200.
[0053] The described latch 700 includes a fixed seat 710 and a locking piece 720. The cross-section of the fixed seat 710 is in a "ji" shape, and the locking piece 720 is in an "L" shape. Fixing holes are provided on both sides of the fixed seat 710. The latch 700 is fixedly connected to the waterproof steel plate louver 200 through the fixing holes of the fixed seat 710. A transfer hole is provided on the fixed seat 710, and the fixed seat 710 is rotatably connected to the locking piece 720 through the transfer hole.
[0054] A filter cotton is interposed between the large air volume sandwich cotton filter screen plate 500 and the waterproof steel plate louver 200.
[0055] The described filter cotton includes an air inlet layer for intercepting larger sand dust particles, an air outlet layer for finely filtering tiny dust, and a filter layer. The filter layer is interposed between the air inlet layer and the air outlet layer;
