Abstract
Description
Technical Field
[0001] This utility model relates to the field of fireproof roller shutters, specifically a lightweight and convenient fireproof roller shutter. Background Technology
[0002] With the increasing popularity of electric vehicles, the probability of electric vehicles spontaneously combusting in parking spaces is also increasing. Because electric vehicles burn for a long time after catching fire, and there is also a possibility of explosion, traditional fire-fighting methods have weak detection capabilities and limited fire-fighting capabilities for spontaneously combusting electric vehicles. Electric vehicle fires often lead to fires in nearby vehicles and ancillary facilities, resulting in greater losses. Especially in underground parking garages, where professional fire trucks are large and difficult to deploy for fire fighting and rescue, electric vehicle fires in underground parking garages are even more difficult to extinguish. If an electric vehicle fire is not detected, isolated, and contained in time, it is very likely to cause a large amount of property damage and casualties.
[0003] Therefore, if an electric vehicle catches fire in a parking space, the fire must be detected as quickly as possible to prevent it from spreading to more vehicles and nearby facilities. However, underground parking garages contain numerous pipes and irregular spaces. Traditional fire-resistant roller shutters require a large space to release and retract, making them unsuitable for confined environments like underground garages. Therefore, we propose a lightweight and convenient fire-resistant roller shutter. Utility Model Content
[0004] To overcome the limitations of existing fire-resistant roller shutters, which occupy a large area and cannot be adapted to confined installation environments, this utility model provides a lightweight and convenient fire-resistant roller shutter. It uses fire-resistant roller shutter fabric with a thickness of 0.5mm or less, making it lightweight and suitable for confined installation environments.
[0005] The present invention adopts the following technical solution.
[0006] A lightweight and convenient fireproof roller shutter includes:
[0007] The winding box, the winding motor located on one side of the winding box, and the winding drum on the other side;
[0008] The take-up drum is equipped with a take-up shaft. One end of the take-up shaft is connected to the output shaft of the take-up motor via a connecting flange, and the other end is rotatably connected to the take-up drum via a bearing.
[0009] The fireproof roller shutter is connected to the winding shaft, and the winding motor can drive the winding shaft to rotate in both directions through the output shaft, thereby realizing the winding and opening of the fireproof roller shutter.
[0010] The fireproof roller shutter fabric is a single-layer structure, and it is woven from glass fiber with embedded stainless steel wire, with a thickness of less than or equal to 0.5 mm.
[0011] Preferably, a fire extinguishing assembly is also provided, which includes a first water spray pipe, a second water spray pipe, and a water supply pipe. The first water spray pipe is fixedly connected to the lower outer wall of the fireproof roller shutter, and the winding box is provided with a second water spray pipe. The first water spray pipe is provided with a first sprinkler head to spray fire-fighting water to the left and right sides. The inner walls of the circular outer walls at both ends of the second water spray pipe are provided with second sprinkler heads to spray fire-fighting water required for cooling to the left and right sides. The second sprinkler heads are positioned facing the fireproof roller shutter.
[0012] The water supply pipe is connected to both the first water spray pipe and the second water spray pipe.
[0013] Preferably, an extension pipe is provided between the first water spray pipe and the water supply pipe, and a winding reel for winding the extension pipe is connected to the output shaft of the winding motor.
[0014] Preferably, a three-way flow control valve is provided between the water supply pipe, the extension pipe, and the second spray pipe.

[0015] Preferably, temperature sensors are provided on both sides of the winding box, and the temperature sensors are electrically connected to the three-way flow control valve.
[0016] Preferably, a horizontal mounting bracket is provided on the side of the winding box, and a vertical hanger is provided at the top of the winding box.
[0017] The beneficial effects of this utility model are as follows:
[0018] This utility model provides a lightweight and convenient fireproof roller shutter, including a winding box, a winding motor located on one side of the winding box, and a winding drum on the other side; the winding drum has a winding shaft inside, one end of the winding shaft is connected to the output shaft of the winding motor through a connecting flange, and the other end is rotatably connected to the winding drum through a bearing; a fireproof roller shutter fabric is connected to the winding shaft, and the winding motor can drive the winding shaft to rotate forward and backward through the output shaft, thereby realizing the winding and opening of the fireproof roller shutter fabric; the fireproof roller shutter fabric is a single-layer structure, and the fireproof roller shutter fabric is woven from glass fiber with embedded stainless steel wire, and its thickness is less than or equal to 0.5mm. The fire-resistant roller shutter fabric adopts a single-layer flexible structure with a warp tensile strength greater than 2926.4 N / 5 cm and a weft tensile strength of 2526.2 N / 5 cm. It can withstand strong impacts without breaking. Thanks to the thickness of the fire-resistant roller shutter fabric being less than or equal to 0.5 mm, the winding box structure is small in size. Under the same working conditions, it saves about 0.3 m to 0.35 m of net height compared to the top box structure of traditional fire-resistant roller shutter products, thus saving a lot of installation space.

[0025] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0026] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0027] A lightweight and convenient fireproof roller shutter includes a winding box 1, a winding motor 11 on one side of the winding box 1, and a winding drum 12 on the other side. A winding shaft 13 is installed inside the winding drum 12. One end of the winding shaft 13 is connected to the output shaft of the winding motor 11 via a connecting flange, and the other end is rotatably connected to the winding drum 12 via a bearing. A fireproof roller shutter fabric 2 is connected to the winding shaft 13. The winding motor 11 can drive the winding shaft 13 to rotate forward and backward via its output shaft, thereby realizing the winding and unwinding of the fireproof roller shutter fabric 2.
[0028] Fire-resistant roller shutter fabric 2 is a single-layer structure, woven from fiberglass with embedded stainless steel wires, with a thickness of less than or equal to 0.5mm. The fire resistance rating of fire-resistant roller shutter fabric 2 is 4 hours.
[0029] In some embodiments, a fire extinguishing assembly is also provided, which includes a first water spray pipe 31, a second water spray pipe 32, and a water supply pipe 33. The lower outer wall of the fireproof roller shutter 2 is fixedly connected to the first water spray pipe 31, and the winding box 1 is provided with the second water spray pipe 32. The first water spray pipe 31 is provided with a first sprinkler head 311 to spray fire-fighting water required for fire extinguishing to the left and right sides. The second water spray pipe 32 is provided with a second sprinkler head 321 to spray fire-fighting water required for cooling to the left and right sides of the fireproof roller shutter 2. The water supply pipe 33 is connected to both the first water spray pipe 31 and the second water spray pipe 32. The first sprinkler head 311 of the first water spray pipe 31 can spray water to both sides over a large area, forming a large isolation zone and further slowing down the spread of the fire. The second sprinkler head 321 of the second water spray pipe 32 can fully cool the fireproof roller shutter 2, thereby preventing the fireproof roller shutter 2 from being burned through and losing its function of blocking flames. Furthermore, the first water spray pipe 31 can also act as a counterweight, making the fireproof roller shutter 2 more stable during the opening process.
[0030] In some embodiments, a three-way flow regulating valve 34 is provided between the water supply pipe 33 and the first water spray pipe 31 and the second water spray pipe 32. The first water spray pipe 31 and the second water spray pipe 32 are respectively connected to the outlet of the three-way flow regulating valve 34, and the inlet of the three-way flow regulating valve 34 is connected to the water supply pipe 33.
[0031] In some embodiments, an extension pipe 312 is provided between the first water spray pipe 31 and the water supply pipe 33, and a winding disc 14 for winding the extension pipe 312 is connected to the output shaft of the winding motor.
[0032] In some embodiments, temperature sensors are installed on both sides of the winding box 1, and the temperature sensors are electrically connected to the three-way flow control valve 34. Based on the data from the temperature sensors, the three-way flow control valve 34 can automatically adjust the flow rates of the first water spray pipe 31 and the second water spray pipe 32. In the initial stages of a fire, the fire source is far from the temperature sensor, and the temperature detected by the sensor is low. At this time, the three-way flow control valve 34 directs the water flow from the water supply pipe 33 mainly to the first water spray pipe 31, and the first sprinkler head 311 sprays water onto both sides of the fireproof roller shutter 2, forming a larger isolation zone to slow the spread of the fire. When the temperature detected by the temperature sensor is high or low, it indicates that the fire source has spread to the vicinity of the fireproof roller shutter. At this point, spraying water onto both sides of the fireproof roller shutter 2 through the first sprinkler head 311 to stop the spread of the fire is no longer effective. Therefore, the three-way flow control valve 34 then directs the water flow from the water supply pipe 33 mainly to the second sprinkler head 321, which sprays water onto the fireproof roller shutter 2 to cool it down.
[0033] In some embodiments, a horizontal mounting bracket 41 is provided on the side of the winding box 1, and a vertical hanger 42 is provided at the upper end of the winding box 1. The horizontal mounting bracket 41 and the vertical hanger 42 can achieve stable installation of the entire winding box 1.
[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
