Description

Technical Field

[0001] This application relates to the field of louvers, specifically a curved type of louver that is resistant to high-speed impacts and wind and sand. Background Technology

[0002] In power plant turbine rooms, boiler rooms, control buildings, etc. in desert areas, it is necessary to effectively block high-speed sandstorms from entering while ensuring ventilation. Conventional louvers are far from meeting the requirements for sandstorm protection, and various equipment will always be covered by sandstorms, which can seriously affect the performance and service life of the equipment.

[0003] Chinese patent document CN219241769U discloses an adjustable rainproof and sandproof louver, specifically disclosing the window frame. A first motor slot is located at the lower end of one longitudinal frame of the window frame. An inner window is installed inside the window frame, and the inner window includes an inner frame. Multiple longitudinally arranged window slats are rotatably connected between the two longitudinal frames of the inner frame. The beneficial effects of this patent are: the multiple window slats are rotatably connected to the two longitudinal frames of the inner frame on both sides, facilitating adjustment of the window slat angle; the window slats are configured as main slats and secondary slats; multiple ventilation holes are opened at the bottom of the main slats, allowing ventilation through these holes after the louver is closed in windy or sandy weather; and the filter screens on the ventilation holes filter the sand and dust outdoors, achieving a sandproof function.

[0004] In the aforementioned patent, the diameter of the ventilation holes is relatively small, and the ventilation efficiency is even lower after a filter screen is installed on the ventilation holes. Although this can improve the sand-proof effect, it reduces the overall ventilation efficiency. Utility Model Content

[0005] In order to overcome the problem that existing technologies reduce ventilation efficiency in order to improve sand protection performance, this application provides a curved louver that is resistant to high-speed impacts and sandstorms.

[0006] This application adopts the following technical solution: a curved anti-high-speed impact and anti-sand louver, including a window frame, a louver plate is provided at one end of the inner side of the window frame, and an anti-sand mechanism is provided at the other end of the inner side of the window frame, the anti-sand mechanism being located on the rear side of the louver plate.

[0007] The wind and sand prevention mechanism includes a first frame and a screen. The outer wall of the first frame is attached to the inner wall of the window frame. The screen is covered on the inner side of the first frame. An overflow plate is provided on the top of the side of the first frame facing the louver panel. The overflow plate extends along the width direction of the first frame. A water inlet pipe is provided between the overflow plate and the first frame. The water inlet pipe is used to transport water into the overflow plate.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figure 1-4 As shown, the curved anti-high-speed impact and anti-sand louver includes a window frame 1, a louver panel 2 is provided at one end of the inner side of the window frame 1, and an anti-sand mechanism 3 is provided at the other end of the inner side of the window frame 1. The anti-sand mechanism 3 is located on the rear side of the louver panel 2.

[0024] The wind and sand prevention mechanism 3 includes a first frame 31 and a screen 32. The outer wall of the first frame 31 is attached to the inner wall of the window frame 1. The screen 32 is installed on the inner side of the first frame 31. An overflow plate 33 is provided on the top of the side of the first frame 31 facing the louvered panel 2. The overflow plate 33 extends along the width direction of the first frame 31. A water inlet pipe 34 is provided between the overflow plate 33 and the first frame 31. The water inlet pipe 34 is used to transport water into the overflow plate 33.

[0025] The louvered panel 2, located at the front, acts as the first line of defense against wind and sand. Its high structural strength also helps prevent high-speed impacts, reducing the kinetic energy of sand as it passes through. Furthermore, the louvered panel 2 can be designed with a slightly curved shape to disperse the impact force of sand and enhance its resistance to high-speed impacts. When sandstorms are severe, water can be slowly introduced into the overflow plate 33 through the water inlet pipe 34. The water overflowing from the overflow plate 33 flows along its outer wall to the surface of the mesh screen 32, forming a water curtain that effectively blocks sand and dust. Wind can pass through this water curtain, achieving efficient sand control while minimizing airflow loss and ensuring that ventilation efficiency does not decrease significantly.

[0026] The window frame 1 has a second frame 11 inside, and the louvered panel 2 is installed on the inner side of the second frame 11. The window frame 1 also has a first limiting frame 12 and a second limiting frame 13. The first limiting frame 12 is used to fix the first frame 31, and the second limiting frame 13 is used to fix the second frame 11. The first limiting frame 12 and the second limiting frame 13 play a role in fixing and limiting the first frame 31 and the second frame 11, ensuring that the first frame 31 and the second frame 11 will not shift when the wind is strong.

[0027] A water-blocking strip 120 is provided on the inner bottom of the first limiting frame 12. The water-blocking strip 120 is located at the end of the first limiting frame 12 away from the screen 32. The water-blocking strip 120 serves to block water, preventing water from flowing from above the screen 32 to below the screen 32 and then to the rear of the first frame 31. In other words, the water-blocking strip 120 can prevent water from flowing to the inside of the house.

[0028] A water trough 14 is provided at the bottom of the window frame 1, located between the first frame 31 and the second limiting frame 13. A water storage cavity 4 is provided below the window frame 1, which is connected to the water trough 14. The water storage cavity 4 can be separately installed from the window frame 1 or placed inside the window frame 1. A filter plate 41 and a water pump 42 are provided inside the water storage cavity 4. The water pump 42 is located below the filter plate 41, and its outlet is connected to the inlet pipe 34.

[0029] After flowing to the bottom of the screen 32, the water will overflow onto the inner wall of the window frame 1, and then flow into the water storage chamber 4 through the water trough 14. The filter plate 41 in the water storage chamber 4 filters the water, and under the pumping action of the water pump 42, the filtered water can be pumped into the overflow plate 33 to realize the recycling of water and reduce the amount of external water added.

[0030] The water inlet pipe 34 extends along the inner wall of the window frame 1, thus ensuring that the water inlet pipe 34 can be reliably fixed and prevented from swinging and breaking due to wind and sand. This ensures that the water in the water storage chamber 4 can be reliably pumped into the overflow plate 33, thereby ensuring that there is enough water to form a water curtain.

[0031] A sand guide plate 20 is provided below the louver panel 2. One end of the sand guide plate 20 is located inside the second frame 11, and the other end is located inside the second limiting frame 13. The height of the sand guide plate 20 gradually decreases from the second frame 11 to the second limiting frame 13. As wind and sand pass through the louver panel 2, some sand and dust will be trapped inside. This sand and dust will flow downwards along the louver panel 2 and flow into the water storage cavity 4 under the guidance of the sand guide plate 20, thereby collecting the sand and dust and preventing it from falling to the outside of the window frame 1 and then being carried by the wind and sand to the inside of the window frame 1, thus improving the wind and sand protection effect.

[0032] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
