[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an electric smoke barrier vertical wall outlet fixing device, including a wall body 1 and a counterweight 8.

The top ends of the left and right sides of the inner wall of the wall body 1 are fixedly connected with a fixing plate 4. A winding machine 5 is fixedly connected between the adjacent two fixing plates 4. A plurality of long baffles 6 are arranged between the adjacent winding machine 5 and the counterweight 8. The top walls of the plurality of long baffles 6 are fixedly connected with a plurality of rotating buckles 7 at equal distances. The plurality of rotating buckles 7 are rotatably connected to the bottom ends of the plurality of long baffles 6. The top long baffle 6 is fixedly connected to the inside of the winding machine 5. The front and rear sides of the top wall of the counterweight 8 are fixedly connected with a triangular block 9. The inner top wall of the wall body 1 is provided with two triangular grooves 10. The two triangular blocks 9 are meshed and connected with the two triangular grooves 10. The two fixed plates 4 are fixedly connected to the rotating motor 11 on the far side thereof. The output ends of the two rotating motors 11 are fixedly connected to the inside of the winding machine 5. A smoke exhaust mechanism 2 is arranged on the rear side of the inner top wall of the wall body 1.

[0040] Specifically, during operation, the rotating motor 11 drives the winding machine 5 to rotate. Since the barrier is composed of multiple long baffles 6 and multiple rotating buckles 7, it has a certain degree of foldability, so that the winding machine 5 can realize the winding and releasing of the long baffles 6 through the internal winding shaft. In the process of raising the smoke barrier vertical wall, the counterweight 8 plays a role of balance and stability. The counterweight 8 is engaged and connected with the triangular groove 10 on the wall 1 through the triangular block 9 on its top wall, ensuring that the smoke barrier vertical wall can maintain an engaged state with the wall 1 after raising. When the vertical wall needs to be lowered, the rotating motor 11 drives the winding machine 5 to release the long baffle 6. The long baffle 6 slides down along the guide groove 3 under the traction of the counterweight 8 to form the required smoke barrier, ensuring that the smoke barrier vertical wall can move smoothly during the descent process to avoid shaking or tilting. At the same time, the presence of the counterweight 8 also reduces the driving force required by the rotating motor 11, and the equipment will not be unable to complete the descent operation due to deviation in the descent angle during descent, thereby improving the working efficiency of the entire device in the event of a fire, and providing valuable time for personnel evacuation and fire fighting and rescue.

A plurality of baffles 205 are fixedly connected to the upper and lower sides of the inner walls of the plurality of smoke exhaust grooves 204 at equal distances. The inner top walls of the plurality of smoke exhaust grooves 204 are all connected to a smoke exhaust pipe 206, and a fan 207 is fixedly installed in the middle of the inner wall of the smoke exhaust pipe 206.

[0042] Specifically, the smoke guide strip 201 can effectively guide the smoke to the predetermined smoke exhaust channel when a fire occurs. Once the smoke alarm 202 senses the presence of smoke, it will immediately start the smoke exhaust mechanism 2 to start the smoke exhaust work. The smoke exhaust plate 203 is located in the middle of the inner top wall of the wall 1. On the rear side of the smoke exhaust plate 203, a plurality of smoke exhaust grooves 204 are opened. These smoke exhaust grooves 204 can ensure that smoke can enter and be discharged smoothly. On the upper and lower sides of the inner wall of each smoke exhaust groove 204, a plurality of baffles 205 are fixed at equal distances. These baffles 205 not only The structural strength of the smoke exhaust trough 204 is enhanced, and the flow rate of the smoke can be slowed down to a certain extent, so that it can enter the smoke exhaust pipe 206 more evenly. The smoke exhaust pipe 206 is an important passage connecting the smoke exhaust trough 204 and the fan 207. When the smoke enters the smoke exhaust trough 204, it will flow to the fan 207 through the smoke exhaust pipe 206. The fan 207, as the power source of the smoke exhaust mechanism 2, can start quickly after receiving the signal from the smoke alarm 202, generate strong suction, suck in the smoke and discharge it to the outside through the pipe, providing a strong guarantee for the safety of the building.

[0043] Reference Figure 1 , Figure 2 and Figure 4 , multiple emergency power supplies 12 are fixedly connected to the left side of the inner bottom wall of the wall 1, and the outer walls of the multiple emergency power supplies 12 are all provided with power supply protection shells 13; two manual switch buttons 15 are fixedly installed in the middle of the left side of the inner wall of the wall 1; two thermometers 16 are fixedly connected to the lower middle of the left side of the inner wall of the wall 1;

[0044] Specifically, the setting of multiple emergency power supplies 12 can provide power to the smoke barrier wall when the main power supply is interrupted to ensure its normal operation. The power supply protection shell 13 can protect the emergency power supply 12 to prevent it from external physical damage or environmental influences. Through two manual switch buttons 15, the user can manually control the opening and closing of the smoke barrier wall when the automatic control system fails or emergency operation is required. Two thermometers 16 are used to monitor the temperature at the exit and entrance near the smoke barrier wall in real time.

[0045] Reference Figure 1 , Figure 3 and Figure 4 Two guide plates 14 are fixedly connected to the left and right sides of the inner bottom wall of the wall 1, and the top ends of the two guide plates 14 are designed to be smooth; the left and right ends of the counterweight 8 are rotatably connected to multiple sliding wheels 17, and the outer walls of the multiple sliding wheels 17 are slidably connected to the front and rear sides of the inner walls of the two guide grooves 3; the bottom end of the smoke exhaust pipe 206 is designed to be inverted cone;

[0046] Specifically, the smooth design of the top of the guide plate 14 can ensure that the smoke barrier wall reduces friction and resistance during lifting or moving, ensuring smooth movement. The sliding wheel 17 allows the counterweight 8 to slide easily in the guide groove 3 to achieve balanced adjustment. The bottom end of the smoke exhaust pipe 206 is designed to be an inverted cone, which helps to better collect and discharge smoke.

[0047] Working principle: When working, the rotating motor 11 drives the winding machine 5 to rotate. Since the barrier is composed of multiple long baffles 6 and multiple rotating buckles 7, it has a certain degree of foldability, so that the winding machine 5 can realize the winding and releasing of the long baffles 6 through the internal winding shaft. In the process of raising the smoke barrier vertical wall, the counterweight 8 plays a role of balance and stability. The counterweight 8 is engaged and connected with the triangular groove 10 on the wall 1 through the triangular block 9 on its top wall, ensuring that the smoke barrier vertical wall can maintain an engagement state with the wall 1 after raising. When the vertical wall needs to be lowered, the rotating motor 11 drives the winding machine 5 to release the long baffle 6. The long baffle 6 slides down along the guide groove 3 under the traction of the counterweight 8 to form the required smoke barrier. At the same time, the existence of the counterweight 8 also reduces the driving force required by the rotating motor 11, and the equipment will not be unable to complete the lowering operation due to deviation in the lowering angle during descent.

[0048] The smoke guide strip 201 can effectively guide the smoke to the predetermined smoke exhaust channel when a fire occurs. Once the smoke alarm 202 senses the presence of smoke, it will immediately start the smoke exhaust mechanism 2 to start the smoke exhaust work. The smoke exhaust plate 203 is located in the middle of the inner top wall of the wall 1. On the rear side of the smoke exhaust plate 203, a plurality of smoke exhaust grooves 204 are opened. These smoke exhaust grooves 204 can ensure that smoke can enter and be discharged smoothly. On the upper and lower sides of the inner wall of each smoke exhaust groove 204, a plurality of blocking strips 205 are equidistantly fixed. These blocking strips 205 are arranged on the upper and lower sides of the inner wall of each smoke exhaust groove 204. Strip 205 not only enhances the structural strength of the smoke exhaust trough 204, but also slows down the flow rate of the smoke to a certain extent, allowing it to enter the smoke exhaust pipe 206 more evenly. The smoke exhaust pipe 206 is an important passage connecting the smoke exhaust trough 204 and the fan 207. When the smoke enters the smoke exhaust trough 204, it will flow to the fan 207 through the smoke exhaust pipe 206. The fan 207, as the power source of the smoke exhaust mechanism 2, can start quickly after receiving the signal from the smoke alarm 202, generate strong suction, suck in the smoke and discharge it outdoors through the pipe.
