Technical Field

[0001] The utility model relates to the technical field of building ventilation and smoke exhaust, and particularly relates to an integrated system for building ventilation and smoke prevention and exhaust. Background Technique

[0002] A building ventilation system is a building environment control technology for ensuring the quality of indoor and outdoor air environments. By means of ventilation dilution or ventilation exhaust, it controls the spread and harm of air pollutants. The ventilation system usually includes a set of devices such as an air inlet, an air outlet, a supply air duct, a fan, cooling and heating, a filter, a control system, and other auxiliary equipment.

[0003] According to the Chinese patent with the authorized publication number CN221279612U, a building ventilation system is disclosed. The fan housing is fixed on the wall, and a fan, an air suction pipe, and an air suction port are arranged inside the fan housing, so as to achieve the effect of building ventilation through the fan, the air suction pipe, and the air suction port.

[0004] In the actual use process of the above solution, it generally can only achieve the effect of building ventilation, and is independently set up with the smoke prevention and exhaust system. Therefore, due to the independence of the ventilation and smoke exhaust systems, there is a problem of time delay during the conversion of use, and the system complexity is relatively high, increasing the operation difficulty of the staff, and the subsequent maintenance cost is large, which is not conducive to quickly and effectively dealing with emergencies. For this reason, the utility model provides an integrated system for building ventilation and smoke prevention and exhaust. Content of the Utility Model

[0017] By adopting this technical solution, it ensures that the filter screen can be effectively installed and fixed by the insertion rods.

[0018] Furthermore, the bottom end of the bidirectional screw sequentially penetrates through the smoke exhaust pipe and the adjustment block and is rotatably connected to the smoke exhaust pipe through a bearing.

[0019] By adopting this technical solution, it ensures that the bidirectional screw can rotate stably and effectively in place.

[0020] Further, the sum of the heights of the two baffles is greater than the height inside the smoke exhaust duct, and the width of the baffle is greater than the width inside the smoke exhaust duct.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 5 , the present invention provides an integrated system for building ventilation and smoke prevention and exhaust, including an air inlet duct 1, an air outlet duct 2 fixed to the bottom of the air inlet duct 1, a smoke exhaust duct 3 fixed to the left side of the air inlet duct 1, a conversion mechanism 4 provided outside the air inlet duct 1 for realizing the conversion of ventilation and smoke exhaust functions, an air inlet 6 fixed to the right side of the air inlet duct 1, and an installation assembly 9 installed inside the air inlet 6.

[0034] Through the coordinated use of the air inlet duct 1, the air outlet duct 2, the smoke exhaust duct 3, and the conversion mechanism 4, during actual use, it can automatically and quickly and effectively switch from the ventilation mode to the smoke exhaust mode according to the smoke situation in the ventilation duct, thereby effectively reducing the corresponding time, effectively reducing the operation difficulty of the staff, being beneficial to quickly and effectively coping with emergencies, and can also automatically adjust the opening degree of the smoke exhaust port according to the concentration and distribution of the smoke, so as to achieve efficient smoke exhaust, and can also close the ventilation ports in non-critical areas to reduce the spread of smoke, improving the practicability of the integrated system for building ventilation and smoke prevention and exhaust.

[0035] In this embodiment, the conversion mechanism 4 is a structure for realizing the conversion of ventilation and smoke exhaust functions.

[0036] Such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, the conversion mechanism 4 includes a protective frame 401 fixed to the top of the air inlet duct 1, a controller 402 fixed to the top of the air inlet duct 1, a backup battery 403 fixed to the top of the air inlet duct 1, a ventilation and smoke exhaust assembly 404 disposed inside the air inlet duct 1 for achieving the effect of ventilation and smoke exhaust, and an adjustment assembly 405 disposed inside the smoke exhaust duct 3 for adjusting the smoke exhaust volume.

[0037] It should be noted that the adjustment assembly 405 includes a motor 4051 fixed to the top of the smoke exhaust duct 3, a bidirectional screw 4052 fixed to the output shaft of the motor 4051, two adjustment blocks 4053 threadedly connected to the outer side of the bidirectional screw 4052, a connecting rod 4054 rotatably connected to the left side of the adjustment block 4053 through a pin shaft, and a baffle 4055 rotatably connected to one end of the connecting rod 4054 away from the adjustment block 4053 through a pin shaft.

[0038] Among them, the ventilation and smoke exhaust assembly 404 includes a ventilation fan 4041 fixed inside the air inlet duct 1, a smoke detector 4042 fixed to the inner top wall of the air inlet duct 1, a first fire damper 4043 fixed inside the smoke exhaust duct 3, a smoke exhaust fan 4044 fixed inside the smoke exhaust duct 3, and a second fire damper 4045 fixed inside the air outlet duct 2, ensuring effective ventilation or smoke exhaust of the building.

[0039] In addition, an air outlet 7 is fixed to one side of the air outlet duct 2 away from the air inlet duct 1, a smoke outlet 8 is fixed to the left side of the smoke exhaust duct 3, a filter screen 5 is slidably connected inside the air inlet 6, and protective nets are fixed inside the air outlet 7 and the smoke outlet 8, ensuring that other items or impurities will not enter the inside of the smoke exhaust duct 3, the air inlet duct 1, and the air outlet duct 2.

[0040] It can be understood that the bottom end of the bidirectional screw 4052 sequentially penetrates through the smoke exhaust duct 3 and the adjustment block 4053 and is rotatably connected to the smoke exhaust duct 3 through a bearing, ensuring that the bidirectional screw 4052 can stably and effectively rotate in place. The sum of the heights of the two baffles 4055 is greater than the height inside the smoke exhaust duct 3, and the width of the baffle 4055 is greater than the width inside the smoke exhaust duct 3. Both the ventilation fan 4041 and the smoke exhaust fan 4044 are fans with adjustable speeds, ensuring that through the combined use of the baffle 4055 and the smoke exhaust fan 4044, the smoke exhaust volume can be effectively adjusted according to the actual situation, thereby achieving a more efficient use effect. The controller 402 and the backup battery 403 are both located inside the protective frame 401, ensuring that the protective frame 401 can effectively protect the controller 402 and the backup battery 403. The baffle 4055 is hinged to the left side of the smoke exhaust duct 3 through a hinge, ensuring that the baffle 4055 can effectively rotate on the left side of the smoke exhaust duct 3.

[0041] In this embodiment, the installation assembly 9 is a structure for installing the filter screen 5.

[0042] As Figure 1 and Figure 3 shown, the installation component 9 includes two moving blocks 901 slidably connected inside the air inlet 6. Insertion slots 902 are formed at the top and bottom of the filter net 5. Insertion rods 903 are fixed inside the moving blocks 901. Springs 904 are fixed on the opposite sides of the two moving blocks 901. Adjustment slots 905 are formed at the top and bottom of the air inlet 6.

[0043] It should be noted that the moving blocks 901 are slidably connected inside the adjustment slots 905. Opposite ends of the two insertion rods 903 sequentially penetrate through the moving blocks 901, the air inlet 6, the filter net 5, and the insertion slots 902 and are inserted into the insertion slots 902, ensuring that the filter net 5 can be effectively installed and fixed through the insertion rods 903. The springs 904 are fixed inside the adjustment slots 905, ensuring that the springs 904 can achieve the expected elastic effect.

[0044] Electrical components appearing in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0045] The working principle of the above embodiment is as follows:

[0046] During use, through the cooperation of the air inlet duct 1, the air outlet duct 2, and the ventilation fan 4041, the effect of building ventilation is achieved. When the smoke detector 4042 detects that the concentration of smoke reaches a certain value, it transmits a signal to the controller 402. Then, the first fire damper 4043 is opened and the second fire damper 4045 is closed through the controller 402 to prevent smoke from spreading from the air outlet duct 2. Then, the smoke exhaust fan 4044 and the motor 4051 are turned on. The motor 4051 drives the bidirectional screw 4052 to rotate. Under the action of the internal threaded rotation thrust, the adjustment block 4053 moves up and down on the outside of the bidirectional screw 4052, thereby driving the baffle 4055 to rotate through the connecting rod 4054. Thus, according to the concentration of smoke, the angle of the baffle 4055 and the rotation speed of the smoke exhaust fan 4044 can be effectively adjusted to achieve more efficient smoke exhaust. And a backup battery 403 is added to ensure that the smoke exhaust system can still work normally in case of a power failure. And after using for a period of time, the two insertion rods 903 are respectively pulled up and down, so that the insertion rods 903 are separated from the insertion slots 902. At this time, the springs 904 are in a stretched state, and thus the filter net 5 can be taken out of the air inlet 6 for cleaning to ensure the subsequent use effect. And under the action of the restoring force of the springs 904, the filter net 5 can be conveniently and effectively reinstalled.

[0047] Compared with the prior art, in the integrated building ventilation and smoke exhaust prevention system, through the coordinated use of the air inlet duct 1, the air outlet duct 2, the smoke exhaust duct 3, and the controller 402, the smoke detector 4042, the smoke exhaust fan 4044, and the baffle 4055 in the conversion mechanism 4, during actual use, it can automatically and quickly and effectively switch from the ventilation mode to the smoke exhaust mode according to the smoke situation in the ventilation duct, thereby effectively reducing the corresponding time, effectively reducing the operation difficulty of the staff, being beneficial to quickly and effectively dealing with emergencies, and can also automatically adjust the opening degree of the smoke exhaust outlet according to the concentration and distribution of the smoke, so as to achieve efficient smoke exhaust, and can also close the ventilation outlets in non-critical areas to reduce the spread of smoke, improving the practicability of the integrated building ventilation and smoke exhaust prevention system and solving the problem of low practicability of the existing building ventilation system.
