The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] For examples, please refer to Figures 1-5 This utility model provides a technical solution:
[0030] An adjustable aluminum blade fire exhaust fan includes an exhaust base 1 and a mounting plate 2 disposed on the front side of the exhaust base 1. A controller 3 is embedded in the top of the exhaust base 1. An alarm 4 and an indicator light 5 are respectively installed on the left side of the exhaust base 1. A smoke and fire sensor 6, a connecting block 7 and a moving groove 8 are respectively disposed on the rear side of the exhaust base 1. An adjusting motor 701 is disposed on the top of the connecting block 7. An adjusting screw 702 and a positioning rod 703 are respectively disposed on the opposite side surface of the connecting block 7. An exhaust fan 9 and an adjusting groove 10 are respectively disposed inside the exhaust base 1. A fire-resistant aluminum blade 1001 is slidably disposed inside the adjusting groove 10. Adjusting blocks 1002 are fixedly installed on both the left and right ends of the rear side of the fire-resistant aluminum blade 1001. An exhaust hole 11 is disposed on the front side of the exhaust base 1. A hole groove 201 and a bolt groove 202 are respectively opened on the rear surface of the mounting plate 2. A split mounting mechanism 12 is disposed between the mounting plate 2 and the exhaust base 1.
[0031] Specifically, the alarm 4 and the indicator light 5 are electrically connected to the controller 3 via wires, and the smoke sensor 6 and the smoke exhaust fan 9 are electrically connected to the controller 3 via wires.
[0032] In this implementation scheme, the smoke and fire sensor 6 can monitor smoke and fire in real time and start the smoke exhaust fan 9 through the controller 3 to accelerate the smoke discharge. At the same time, it triggers the alarm 4 and indicator light 5, which makes it easier for staff to judge the status of the smoke exhaust fan and facilitates subsequent handling operations.
[0033] Specifically, the movable groove 8 is opened on the left and right end surfaces of the rear side of the smoke exhaust seat 1. The rear end of the adjusting block 1002 extends to the rear side of the smoke exhaust seat 1 through the movable groove 8. The bottom end of the adjusting screw 702 is threaded through the top surface of the adjusting block 1002 and extends downward. The positioning rod 703 fits through the top surface of the adjusting block 1002 and extends downward. The output end of the adjusting motor 701 passes through the top surface of the connecting block 7 and is fixed to the top end of the adjusting screw 702. The bottom inner wall of the adjusting groove 10 is flush with the bottom surface of the smoke exhaust seat 1.
[0034] In this embodiment, the regulating motor 701 is a reciprocating motor, and it is electrically connected to the controller 3 via a wire. The regulating motor 701 is mainly used to drive the regulating screw 702. Through the threaded transmission between the regulating screw 702 and the regulating block 1002, and the sliding cooperation between the positioning rod 703 and the regulating block 1002, the regulating block 1002 causes the flame-arresting aluminum blade 1001 to move up and down, thereby achieving the function of adjusting the position of the flame-arresting aluminum blade 1001 and ensuring the smoke exhaust efficiency of the smoke exhaust fan.
[0035] It should be noted that the outer surface of the exhaust hole 11 is in contact with the inner wall of the slot 201, and the mounting plate 2 is fixedly installed on the wall by the combination of the bolt and the bolt slot 202.
[0036] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The split-type installation mechanism 12 includes a front mounting block 1201 and a rear mounting block 1202. The front mounting block 1201 is fixedly installed on the left and right ends of the mounting plate 2. A slot 1203 is provided on the rear surface of the front mounting block 1201. The rear mounting block 1202 is fixedly installed on the left and right sides of the exhaust seat 1. A square groove 1204 is provided on the rear surface of the rear mounting block 1202. A guide post 1205 is provided inside the square groove 1204. A guide block 1206 and a tension spring 1207 are fitted and sleeved on the outer side of the guide post 1205. A locking block 1208 is fixedly installed on the front side of the guide block 1206.
[0037] Specifically, the front mounting block 1201 and the rear mounting block 1202 are located on the same straight line. The inner wall of the front end of the square groove 1204 extends to the front surface of the rear mounting block 1202. The guide block 1206 is symmetrically distributed about the inner central axis of the guide post 1205. The rear end of the guide block 1206 is higher than the rear surface of the rear mounting block 1202. The left and right ends of the extension spring 1207 are in fixed contact with the opposite side surfaces of the guide block 1206. The outer surface of the locking block 1208 is fitted and engaged with the inner wall of the locking groove 1203.
[0038] In this embodiment, the guide post 1205 and guide block 1206 guide the locking block 1208 to slide automatically into the locking slot 1203, and the extension spring 1207 ensures close contact between the locking block 1208 and the locking slot 1203, which greatly improves the installation efficiency.
[0039] The working process of this utility model is as follows: When using an adjustable aluminum blade fire exhaust fan, firstly, the mounting plate 2 is fixedly installed on the wall. Then, the exhaust seat 1 is moved, causing the rear mounting block 1202 to contact the front mounting block 1201. Subsequently, the locking block 1208 comes into close contact with the locking groove 1203. During the contact process, the locking blocks 1208 move towards each other and compress the extension spring 1207 until the locking blocks 1208 are fully inserted into the locking groove 1203. At this time, the compressed extension spring 1207 begins to elastically release and passes through the guide block 1206. The drive blocks 1208 move in opposite directions, achieving a tight fit between the blocks 1208 and the inner wall of the slot 1203. This allows for the rapid installation of the smoke exhaust seat 1 and facilitates subsequent maintenance and disassembly, meeting the needs of maintenance personnel. Furthermore, the smoke and fire sensor 6 can measure smoke and fire in real time. Once an abnormality is detected, the controller 3 immediately starts the smoke exhaust fan 9 to accelerate smoke discharge, while simultaneously triggering the alarm 4 and indicator light 5. This allows for easy indication of equipment status in emergency situations, helping on-site personnel quickly determine whether the fan is working properly and improving the practical effect of the smoke exhaust fan.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
