Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust valve technology, specifically to a high-efficiency smoke exhaust valve. Background Technology

[0002] A smoke exhaust valve is a valve installed at the end of each branch pipe (smoke inlet) of a mechanical smoke exhaust system. It is normally closed and meets the air leakage requirements. In case of fire, it can be opened manually or electrically to exhaust smoke and ensure the safety of personnel evacuation and fire fighting operations.

[0003] In real-world applications, dust and debris may enter the smoke exhaust valve, jamming its moving parts and preventing it from opening or closing properly. During a fire, this jamming prevents the valve from opening, hindering the timely removal of indoor smoke. This leads to rapid smoke accumulation within the building, reduced visibility, and difficulties in evacuation. Furthermore, the harmful substances in the smoke can threaten human safety. Therefore, a solution is needed to prevent dust and debris from falling into the smoke exhaust valve and jamming the blades, thus improving the stability of the smoke exhaust valve. Utility Model Content

[0004] The purpose of this utility model is to provide a highly efficient smoke exhaust valve to solve the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a high-efficiency smoke exhaust valve, comprising:

[0006] Smoke exhaust valve body;

[0007] The collection component includes a filter hole, a mounting groove, and a mounting frame. The filter hole is located on the inner bottom surface of the smoke exhaust valve body, the mounting groove is located on the outer bottom surface of the smoke exhaust valve body, and the filter hole and the mounting groove are interconnected. The mounting frame is placed inside the mounting groove.

[0008] Furthermore, an actuator is fixed to the top surface of the smoke exhaust valve body, and blades are rotatably installed inside the smoke exhaust valve body.

[0009] Furthermore, two sets of mounting holes are provided on both sides of the mounting frame, and springs are fixed inside the mounting holes.

[0010] Furthermore, a retaining post is fixed to the outer surface of the spring, and one end of the retaining post is inserted into the mounting hole.

[0011] Furthermore, slots are provided on both sides of the lower end of the smoke exhaust valve body, and the end of the locking post extends into the slot.

[0012] Furthermore, it also includes an adjustment component, which includes a fixing frame, a mounting platform, and a motor. The fixing frame is fixed to one side of the smoke exhaust valve body, and a rotating hole is provided in the center of the fixing frame. The mounting platform is fixed to one side of the fixing frame, and a motor is fixed on the upper surface of the mounting platform.

[0013] Furthermore, the output end of the motor is connected to a rotating shaft, which rotates through a rotating hole, and fan blades are fixed on the outer surface of the rotating shaft.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through its exhaust valve body, actuator, blades, and collection assembly, ensures that when dust and impurities enter the exhaust valve body, they fall to the bottom surface of the valve body and are filtered through the filter holes, falling into the mounting frame. This prevents dust and impurities from settling on the bottom surface of the exhaust valve body and affecting blade rotation. When the mounting frame is full of dust, maintenance personnel can press the locking pin inward. The locking pin, driven by a spring, compresses within the mounting hole, causing the pin to disengage from the slot. The mounting frame can then be removed from the slot, the dust and impurities emptied, and the frame reinstalled, allowing the locking pin to engage. By collecting dust and impurities within the mounting frame, dust is prevented from falling directly onto the bottom surface of the exhaust valve body. This design ensures that the blades are not obstructed by dust during rotation, maintaining normal speed and trajectory. Cleaning the mounting frame is simple: just press the locking pin inward, causing the spring to compress and disengage the pin from the slot. This design makes cleaning extremely convenient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a high-efficiency smoke exhaust valve, comprising:

[0028] Smoke exhaust valve body 11, with an actuator 12 fixed on the top surface of the smoke exhaust valve body 11, and blades 13 rotatably installed inside the smoke exhaust valve body 11;

[0029] The exhaust valve body 11 serves as the main structure of the entire exhaust valve, providing a mounting base for other components. Its internal space forms the exhaust channel. The actuator 12 receives external control signals and transmits power to the blades 13 through its own mechanical structure, driving the blades 13 to rotate within the exhaust valve body 11.

[0030] The collection component includes a filter hole 21, a mounting groove 211, and a mounting frame 22. The filter hole 21 is opened on the inner bottom surface of the smoke exhaust valve body 11, the mounting groove 211 is opened on the outer bottom surface of the smoke exhaust valve body 11, and the filter hole 21 and the mounting groove 211 are interconnected. The mounting frame 22 is placed inside the mounting groove 211.

[0031] The main function of the filter hole 21 is to filter impurities entering the smoke exhaust valve. The mounting groove 211 provides accurate positioning and installation space for the mounting frame 22. The mounting frame 22 can be perfectly embedded in the mounting groove 211. The mounting frame 22 is placed inside the mounting groove 211 to collect dust and impurities filtered from the filter hole 21. It is a detachable component.

[0032] The mounting frame 22 has two sets of mounting holes 23 on both sides. A spring 24 is fixed inside the mounting hole 23. A locking post 25 is fixed on the outer surface of the spring 24. One end of the locking post 25 is inserted into the mounting hole 23. The lower end of the smoke exhaust valve body 11 has a locking groove 26 on both sides. The end of the locking post 25 extends into the locking groove 26.

[0033] The mounting frame 22 provides a mounting platform for components such as the spring 24 and the locking post 25. The spring 24 is fixed in the mounting hole 23 inside the mounting frame 22, and the locking post 25 is installed on one end of the spring 24, with one end of the locking post 25 inserted into the mounting hole 23. The mounting frame 22 provides a stable mounting environment for these components, ensuring that they can work normally and realizing the functions of fixing and easily disassembling the mounting frame 22.

[0034] Working principle:

[0035] When impurities and dust enter the interior of the smoke exhaust valve body 11, they fall into the bottom surface of the smoke exhaust valve body 11. Through the filter hole 21, the dust and impurities fall into the mounting frame 22, preventing them from falling onto the bottom surface of the smoke exhaust valve body 11 and affecting the rotation of the blade 13. When the mounting frame 22 is full of dust, the maintenance personnel can press the locking post 25 inward. The locking post 25 will drive the spring 24 to compress inside the mounting hole 23, causing the locking post 25 to exit from the slot 26. At this time, the mounting frame 22 can be removed from the mounting slot 211, the dust and impurities inside can be emptied, and then the mounting frame 22 can be installed back into the mounting slot 211, so that the locking post 25 is locked into the slot 26. By collecting the impurities and dust inside the mounting frame 22, the dust is prevented from falling directly onto the bottom surface of the smoke exhaust valve body 11. The blade 13 will not be obstructed by dust during rotation and can maintain normal speed and movement trajectory.

[0036] This step involves a simple operation to remove and clean the mounting frame 22. Simply press the locking post 2525 inward to compress the spring 24, causing the locking post 25 to exit from the slot 26, making the mounting frame 22 easy to remove and the cleaning work very convenient.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The adjustment assembly includes a fixed frame 31, a mounting platform 32, and a motor 33. The fixed frame 31 is fixed to one side of the smoke exhaust valve body 11, and a rotating hole is provided in the center of the fixed frame 31. The mounting platform 32 is fixed to one side of the fixed frame 31, and a motor 33 is fixed on the upper surface of the mounting platform 32. The output end of the motor 33 is connected to a rotating shaft, which rotates through the rotating hole, and a fan blade 34 is fixed on the outer surface of the rotating shaft.

[0039] The mounting bracket 31 serves as the basic structure of the entire adjustment assembly, providing a stable and secure mounting platform for other components. A rotating hole is provided in the center of the mounting bracket 31, which provides precise guidance for the installation and rotation of the rotating shaft. The upper surface of the mounting platform 32 is used to mount the motor 33, providing a stable support surface for the motor 33. The motor 33 is the core power component of the entire adjustment assembly, converting electrical energy into mechanical energy. Through the rotating shaft connected to its output end, the power is transmitted to the fan blades 34. The rotation of the motor 33 drives the fan blades 34 to rotate, thereby generating airflow within the smoke exhaust valve body 11 to achieve the function of rapid smoke exhaust.

[0040] Working principle:

[0041] When exhausting smoke, the motor 33 is started by the external controller. The motor 33 drives the rotating shaft to rotate, and the rotating shaft drives the fan blade 34 to rotate, which will increase the flow rate of the smoke exhaust valve. The motor 33 drives the fan blade 34 to rotate, which directly provides additional power for smoke exhaust. The rotation of the fan blade 34 generates a strong airflow thrust, which significantly increases the airflow speed in the smoke exhaust valve.

[0042] This step reduces the residence time and eddy current phenomenon of smoke in the valve body, thereby increasing the amount of smoke discharged per unit time and improving the overall smoke discharge efficiency.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
