Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to an integrated smoke exhaust fan control device. Background Art

[0002] Due to the presence of a large amount of flammable materials in buildings and the widespread risk of fire, a fire extinguishing system must be installed. In this system, the smoke exhaust fan plays a key role. It can quickly remove the smoke in the evacuation passage and prevent smoke from invading the evacuation passage, thereby providing effective protection for people's safe escape. The opening and closing operations of the fan rely on special control equipment. These control devices will have many electrical components inside. These electrical components will generate a certain amount of heat when running, and some smoke exhaust fan control devices will be installed with radiators for heat dissipation. Different devices are installed in different positions, and the wind directions in different directions are different. The heat dissipation holes opened in these devices are generally fixed and cannot be adjusted according to different wind directions. This results in the heat dissipation effect of some heat dissipation fans being not very ideal.

[0003] Chinese Patent Announcement No.: CN219888314U discloses an integrated smoke exhaust fan control device, including a device body, a button and a movable plate, the device body is installed with a button, the outer side of the device body is connected to a movable plate, the outer side of the device body is connected to a first connecting plate, the two ends of the device body are provided with heat dissipation ports, the heat dissipation ports are provided with heat dissipation fans, the outer side of the heat dissipation ports is connected to a second connecting plate, and the second connecting plate is connected to a filter, and the outer side of the second connecting plate is connected to a first insertion rod. The integrated smoke exhaust fan control device is provided with a heat dissipation port, and the heat dissipation fan on the heat dissipation port can dissipate the heat inside the device body to avoid excessive internal temperature of the device body, which may cause a fire, and the filter can filter external dust, so as to facilitate use, and when the filter hole is blocked, the second connecting plate can be disassembled to facilitate disassembly of the filter, so as to facilitate use.

[0004] In the above technology, although the temperature inside the device body can be reduced by setting the heat dissipation port and the heat dissipation fan, the heat dissipation port is fixed and cannot be adjusted according to different wind directions. This may make the heat dissipation fan of some devices not very effective, reducing the heat dissipation effect. At the same time, in rainy weather, a large amount of moisture in the air may pass through the filter and enter the inner wall of the main device, causing damage to the internal electrical components and reducing the service life. In addition, the movable plate is fixed by a magnet when protecting the button. It may lose its original magnetism due to the influence of the external magnetic field or other specific conditions, and its stability and sealing are too low. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 The utility model provides an embodiment: an integrated smoke exhaust fan control device, comprising a control box 1, an air inlet shell 2 is fixedly connected to the right surface of the control box 1, and an adjustment component 3 is arranged on the front surface of the air inlet shell 2;

[0032] The adjusting assembly 3 includes a rotating rod 35, which is rotatably connected to the right end of the front surface of the air inlet shell 2. The outer wall of the rotating rod 35 is fixedly connected to a baffle 31. The baffle 31 can be driven to rotate by rotating the rotating rod 35, and can be adjusted according to the wind direction, thereby improving the heat dissipation effect of the control box 1. The baffle 31 rotates on the right end of the inner wall of the air inlet shell 2. The front end of the outer wall of the rotating rod 35 is fixedly connected to a rotating plate 33. The inner wall of the rotating plate 33 is slidably connected to a sliding rod 36. When the connecting plate 32 is moved, the sliding rod The rear end of 36 will slide on the inner wall of the rotating plate 33, and its front end will rotate on the rear surface of the connecting plate 32 to ensure the continuity of movement between the structures. A rectangular groove 39 is provided on the front surface of the air inlet shell 2, and a slide plate 38 is slidably connected to the inner wall of the rectangular groove 39, and a rectangular plate 37 is fixedly connected to the front surface of the slide plate 38. Multiple groups of baffles 31 are provided, and the multiple groups of baffles 31 are evenly distributed on the right end of the inner wall of the air inlet shell 2. The multiple groups of baffles 31 visually improve the aesthetics and promote air circulation.

[0033] refer to Figure 1 , Figure 2 A control button is provided on the front surface of the control box 1, and the electrical components inside the control box 1 can be controlled by the control button, which is quick and convenient. A rectangular groove 2 10 is provided on the front surface of the control box 1, and the inner wall of the rectangular groove 2 10 is elastically connected to the protective plate 4 through a spring 7. The spring 7 always pushes the protective plate 4 to move upward by its own elasticity, ensuring that the sealing strip 9 of the protective plate 4 is always in contact with the inner wall of the sealing groove 8 when the protective plate 4 is not affected by external forces, thereby ensuring the sealing and connection stability of the protective plate 4. The protective plate 4 is slidably connected to the inner wall of the rectangular groove 2 10, and the sealing strip 9 is fixedly connected to the upper surface of the protective plate 4. A rectangular groove 3 11 is provided on the lower side of the front surface of the control box 1 adjacent to the protective plate 4, and the inner wall of the rectangular groove 3 11 is slidably connected to the movable plate 6.

[0034] Reference Figure 3A threaded rod 34 is threadedly connected to the upper surface of the rectangular plate 37. The threaded rod 34 has the characteristic of self-locking up and down, ensuring that it will not rotate without rotating the threaded rod 34, thereby ensuring the stability of the opening and closing of the baffle 31. A fixing plate 310 is fixedly connected to the front surface of the air inlet shell 2, and the threaded rod 34 is rotatably connected to the upper surface of the fixing plate 310. A connecting plate 32 is fixedly connected to the right surface of the rectangular plate 37, and the front end of the sliding rod 36 is rotatably connected to the rear surface of the connecting plate 32.

[0035] Referring to the figure, a sealing plate 5 is fixedly connected to the front surface of the control box 1, and a sealing groove 8 is provided on the lower surface of the sealing plate 5. A sealing strip 9 contacts the inner wall of the sealing groove 8. The sealing strip 9 is made of rubber and has a certain elasticity. When it enters the inner wall of the sealing groove 8, the spring 7 will squeeze it to a certain extent through elasticity, causing it to deform, thereby increasing the contact area and enhancing the sealing performance. An L-shaped groove 12 is provided at the bottom end of the front surface of the protective plate 4, and the movable plate 6 contacts the inner wall of the L-shaped groove 12. One end of the spring 7 is fixedly connected to the lower surface of the protective plate 4, and the other end of the spring 7 is fixedly connected to the inner wall of the rectangular groove 10.

[0036] Working principle: During use, when the direction of the adjustment component 3 needs to be adjusted according to the wind direction, it is only necessary to rotate the threaded rod 34. At this time, the rectangular plate 37 will move upward or downward on the outer wall of the threaded rod 34, and the rectangular plate 37 will drive the connecting plate 32 to move. At this time, the connecting plate 32 will drive the sliding rod 36 to slide on the inner wall of the rotating plate 33, and the rotating plate 33 will rotate with the center of the circle of the rotating rod 35 as the origin. Due to the angle, the front end of the sliding rod 36 will rotate with the connecting plate 32, and the rotating plate 33 will drive the baffle 31 to rotate through the rotating rod 35. In this way, the opening direction of the baffle 31 can be adjusted, and if it is rainy and the moisture outside is relatively large, the baffle 31 can also be closed by rotating the threaded rod 34 to prevent moisture from entering the interior of the control box 1, thereby improving safety.

[0037] When it is necessary to use the control button set on the front surface of the control box 1, it is only necessary to push the protective plate 4 downward. The protective plate 4 will drive the sealing strip 9 to move downward to disengage it from the inner wall of the sealing groove 8. At the same time, the protective plate 4 will squeeze the spring 7 downward until the movable plate 6 enters the top of the inner wall of the L-shaped slot 12. At this time, the movable plate 6 is pushed to make it stuck on the inner wall of the L-shaped slot 12. In this way, the protective plate 4 can be limited, and the staff can use the control button. After use, the movable plate 6 is pushed in the direction so that the movable plate 6 overlaps with the vertical opening of the L-shaped slot 12. At this time, the spring 7 will push the protective plate 4 upward through its own elasticity. The protective plate 4 will drive the sealing strip 9 to move upward to make it enter the inner wall of the sealing groove 8 to ensure the sealing of the protection.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
