Abstract
Description
Technical Field
[0001] This application relates to the field of fireproof roll technology, and more particularly to a fireproof roll. Background Technology
[0002] Currently, fire-resistant rolls, as a type of fire-fighting equipment, are widely used in fire-resistant partitions of industrial and civil buildings. They effectively prevent the spread of fire and protect life and property, making them an indispensable fire protection facility in modern buildings. A fire-resistant roll is a movable fire-resistant partition, typically made of steel plates or other metal sheets. Normally, it is rolled up in a hinged box above doors and windows; in the event of a fire, it is unrolled to prevent the spread of fire through door and window openings.
[0003] Existing fireproof rolls are usually manually deployed, requiring workers to manually pull down and unfold them when a fire occurs. This method may not be able to be deployed in time in an emergency due to panic or the fire being too large. Therefore, an improvement has been made to a fireproof roll. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a fireproof roll that overcomes these deficiencies. It aims to solve the problem that existing fireproof rolls typically require manual unfolding, meaning that workers must manually pull down and unfold the fireproof roll when a fire occurs. This method may fail to unfold in a timely manner in emergency situations due to panic among personnel or excessive fire intensity.
[0005] To achieve the above objectives, this application provides the following technical solution: a fireproof roll, comprising a wall, a rotating shaft box fixedly installed on the front side of the wall, a rotating shaft rotatably connected inside the rotating shaft box via a bearing seat, a drive unit for driving the rotating shaft to rotate fixedly installed on the side wall of the rotating shaft box, a fireproof roll body wound around the outer surface of the rotating shaft, an outlet extending through the bottom of the rotating shaft box to one side of the rotating shaft, the lower end of the fireproof roll body extending through the outlet to the bottom of the rotating shaft box and fixedly installed with a counterweight, a controller fixedly installed on the front side of the rotating shaft box, and a temperature sensor and a smoke sensor fixedly installed on the lower surface of the rotating shaft box.
[0006] By adopting the above technical solution, and through the coordinated operation of the temperature sensor and the smoke sensor, when the temperature sensor detects that the ambient temperature exceeds the set threshold and the smoke sensor detects that the smoke concentration exceeds the safety threshold, the temperature sensor and the smoke sensor will send a fire signal to the controller. After receiving the signal, the controller will control the drive unit to start, and the rotating shaft will rotate under the drive of the drive unit, thereby automatically unfolding the fireproof roll body. That is, the device realizes the rapid and automatic unfolding of the fireproof roll in emergency situations such as fires through the cooperation between the above components, improving the efficiency and safety of the fireproof roll.
[0007] As a preferred technical solution of this application, a guide rail is fixedly installed on the front side of the wall below the pivot box. A sliding groove is provided inside the guide rail, and the counterweight slides inside the sliding groove. The width of the counterweight is adapted to the width of the sliding groove.
[0008] By adopting the above technical solution, a sliding groove is set to provide a stable downward path for the counterweight, ensuring that the counterweight maintains straightness and stability during movement, so as to ensure that the fireproof roll body can slide smoothly when unfolded.
[0009] As a preferred technical solution of this application, the counterweight has symmetrical notches at both ends, and a movable wheel is rotatably connected inside the notch, with the outer surface of the movable wheel fitting against the inner wall of the sliding groove.
[0010] By adopting the above technical solution, the friction between the counterweight and the sliding groove is reduced by setting up moving wheels, thereby accelerating the downward speed of the fireproof roll body and avoiding jamming.
[0011] As a preferred technical solution of this application, the drive unit includes a fixed seat fixedly installed on the side wall of the shaft box, a drive motor fixedly installed on the top of the fixed seat, one end of the rotating shaft fixedly connected to the output end of the drive motor, and a support block fixedly connected to the bottom of the fixed seat.
[0012] By adopting the above technical solution, the drive motor is fixedly installed on one side of the shaft box by a fixed seat. The fixed seat plays a role in limiting and fixing, ensuring the stability of the drive motor when it is working, and the support block plays a role in reinforcing and supporting.
[0013] As a preferred technical solution of this application, a positioning frame is fixedly installed on the inner wall of the shaft box on one side of the rotating shaft. Two guide rods are rotatably connected inside the positioning frame, and the two guide rods are symmetrically distributed on both sides of the outlet.
[0014] By adopting the above technical solution, the unfolding of the fireproof roll body is guided by the guide rod, and the design of the guide rod can also prevent wrinkles from appearing on the surface of the fireproof roll body.
[0015] As a preferred technical solution of this application, the external dimensions of the counterweight block are larger than the opening size of the outlet.
[0016] By adopting the above technical solution, it is ensured that the counterweight cannot pass through the outlet and enter the interior of the shaft box, thereby preventing the fireproof roll body from being completely retracted into the shaft box and unable to operate.
[0017] As a preferred embodiment of this application, both the temperature sensor and the smoke sensor are connected to the controller signal, and the controller is electrically connected to the drive motor.
[0018] By adopting the above technical solution, fire is detected by temperature and smoke sensors. When a fire is detected, the temperature and smoke sensors will send a fire signal to the controller. After receiving the signal, the controller will control the drive motor to start.
[0019] As a preferred technical solution of this application, the fireproof roll body is made of metal plates such as steel.
[0020] By adopting the above technical solutions, the fireproof roll body made of metal sheets such as steel has a better fireproof effect.

[0022] 1. In this utility model, by setting a temperature sensor and a smoke sensor to work together, when the temperature sensor detects that the ambient temperature exceeds a set threshold and the smoke sensor detects that the smoke concentration exceeds a safety threshold, the temperature sensor and the smoke sensor will send a fire signal to the controller. After receiving the signal, the controller will control the drive motor to start, and the rotating shaft will rotate under the drive of the drive motor, thereby automatically unfolding the fireproof roll body.

That is, the device realizes the rapid and automatic unfolding of the fireproof roll in emergency situations such as fires through the cooperation between the above components, which improves the efficiency and safety of the fireproof roll.
[0033] In this embodiment, as Figure 1 and 2As shown, a guide rail 15 is fixedly installed on the front side of the wall 1 below the pivot box 2. A sliding groove 16 is provided inside the guide rail 15. The counterweight 12 slides inside the sliding groove 16, and the width of the counterweight 12 is adapted to the width of the sliding groove 16.
