Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter technology, specifically a high-performance fireproof roller shutter that saves floor space. Background Technology

[0002] Fireproof roller shutters are fireproof and heat-insulating facilities suitable for large openings in buildings. The product features a concealed roller design, making it structurally sound and compact. It is an indispensable fireproof facility in modern buildings.

[0003] Traditional fire-resistant roller shutters are arranged horizontally, with a minimum center-to-center distance of 400mm between the rollers and a synchronous spacing of 400mm between the roller shutters. If the building's entrance is large, the lowered roller shutter is high and long, resulting in a larger diameter of the rollers after the shutter is retracted, a larger distance between the two rollers, and a larger spacing between the synchronous roller shutters. This leads to a larger area occupied by the roller shutter guide rail. If ordinary fire-resistant roller shutters are installed in parking garages or underground parking lots, the excessive spacing between the two fire-resistant roller shutters results in a large stack for installing the fire-resistant roller shutters at the entrance, significantly affecting the space of the parking spaces near the fire-resistant roller shutters. Therefore, this application proposes a high-performance fire-resistant roller shutter that saves floor space to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-performance fireproof roller shutter that saves floor space, thus solving the problem of large area occupied by roller shutter guide rails.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance fireproof roller shutter that saves floor space, comprising a roller shutter box, wherein two supports are fixed on the left and right side walls of the inner cavity of the roller shutter box, and roller shutter shaft one and roller shutter shaft two are rotatably connected between the upper and lower supports respectively through bearings, and fireproof roller shutter belts are provided on the outer sides of roller shutter shaft one and roller shutter shaft two, and a spray mechanism is provided inside the roller shutter box;

[0006] The spraying mechanism includes spray pipes fixed at both ends of the roller shutter box. The two spray pipes pass through the roller shutter box on opposite sides and extend to the inner bottom wall of the roller shutter box and are connected to the same linear spray pipe. Electric valves are connected to both ends of the linear spray pipe and the two spray pipes.

[0007] Furthermore, a fixing plate is fixed to the inner top wall of the roller shutter box, a special roller shutter motor is fixed to the right side of the fixing plate, a drive sprocket is fixed to the outer side of the output shaft of the special roller shutter motor, and a synchronous sprocket is fixed to the right end of both roller shutter shaft one and roller shutter shaft two. The drive sprocket and the outer side of the two synchronous sprockets are connected by the same synchronous chain.

[0008] Furthermore, the bottom of the roller shutter box is provided with a groove extending into it, and the bottom end of the special roller door motor is connected to a manual chain located in the groove and extending to the bottom of the roller shutter box.

[0009] Furthermore, a controller and a manual button box are provided on the right side of the roller shutter box and on the front side of the external wall, with the manual button box located below the controller.

[0010] Furthermore, guide rails are fixed downwards at the bottom of the roller shutter box and near its left and right ends, and the left and right ends of the fireproof roller shutter belt are respectively located inside the guide rails on the left and right sides.

[0011] Furthermore, the drive sprocket and the two synchronizing sprockets are arranged in a triangular configuration.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This space-saving, high-performance fireproof roller shutter solves the technical problem of traditional fireproof roller shutters with roller door motors, roller shutter shaft one, and roller shutter shaft two arranged horizontally, which occupies a large space. The special roller door motor, roller shutter shaft one, and roller shutter shaft two are arranged in a triangle.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1-2This embodiment of a space-saving high-performance fireproof roller shutter includes a roller shutter box 1. Two supports 2 are fixed on the left and right side walls of the inner cavity of the roller shutter box 1. The upper and lower side supports 2 are respectively rotatably connected by bearings to roller shutter shaft 1 9 and roller shutter shaft 2 10. Fireproof roller shutter belts 12 are provided on the outer sides of roller shutter shaft 1 9 and roller shutter shaft 2 10. A spray mechanism 4 is provided inside the roller shutter box 1.

[0019] A fixing plate 3 is fixed to the inner top wall of the roller shutter box 1. A dedicated roller shutter motor 5 is fixed to the right side of the fixing plate 3. A drive sprocket 6 is fixed to the outer side of the output shaft of the dedicated roller shutter motor 5. Synchronous sprockets 7 are fixed to the right ends of roller shutter shaft 1 9 and roller shutter shaft 2 10. The drive sprocket 6 and the outer side of the two synchronous sprockets 7 are driven by the same synchronous chain 8. A groove extending into the bottom of the roller shutter box 1 is provided. A manual chain located in the groove and extending to the bottom of the roller shutter box 1 is connected to the bottom end of the dedicated roller shutter motor 5. A controller and manual button box are provided on the right side of the roller shutter box 1 and on the front side of the external wall. The button box is located below the controller. The bottom of the roller shutter box 1 and the guide rails 11 extend downwards and are fixed near its left and right ends. The left and right ends of the fireproof roller shutter belt 12 are located inside the left and right guide rails 11 respectively. The drive sprocket 6 and the two synchronous sprockets 7 are triangularly distributed. When it is necessary to roll up the fireproof roller shutter belt 12, the special roller door motor 5 is started, which will drive the drive sprocket 6 to drive the synchronous chain 8 to rotate the two synchronous sprockets 7, and make the roller shutter shaft 1 9 and roller shutter shaft 2 10 start to roll up together. The left and right guide rails 11 can limit the two fireproof roller shutter belts 12 to prevent the fireproof roller shutter belts 12 from being misaligned.

[0020] It is understandable that this application arranges the special roller door motor 5 inside the roller shutter box 1 and the two roller shutter shafts in a triangular configuration, so that the line connecting the two roller shutter shafts forms a certain angle with the horizontal line, thereby reducing the distance between the two roller shutters and ultimately reducing the distance between the two tracks of the roller shutter door, thus saving installation space.

[0021] In this embodiment, the sprinkler mechanism 4 includes sprinkler pipes 401 fixed at both ends of the roller shutter box 1. The two sprinkler pipes pass through the roller shutter box 1 on opposite sides and extend to the inner bottom wall of the roller shutter box 1 and are connected to the same linear sprinkler pipe 403. Both ends of the linear sprinkler pipe 403 are connected to the two sprinkler pipes by electric valves 402. By installing the linear sprinkler pipe 403, the linear sprinkler pipe 403 can be connected to a fire hydrant or sprinkler main pipe through the sprinkler pipe 401 and the opening and closing can be controlled by the electric valves 402 at both ends.

[0022] Understandably, when a fire occurs and the fireproof roller shutter 12 starts and closes, the electric valve 402 starts and opens simultaneously, and the sprinkler system begins to spray water linearly to moisten the fireproof roller shutter 12, which continues to maintain the humidity of the fireproof roller shutter 12, preventing premature carbonization of the fireproof roller shutter 12 and the generation of toxic smoke, so that the fireproof roller shutter 12 can maintain good fire resistance, improve its fire resistance, and achieve the purpose of high fire resistance.

[0023] This application solves the technical problem of the traditional fireproof rolling shutter with 12 rolling door motors, rolling shutter shaft 19, and rolling shutter shaft 210 arranged horizontally, which occupies a lot of space. The special rolling door motor 5, rolling shutter shaft 19, and rolling shutter shaft 210 are arranged in a triangle. The center lines of the two synchronous rolling shafts form an angle with the horizontal line. Utilizing the principle of a right triangle, where the right angle side is smaller than the hypotenuse, the horizontal distance between the two rolling shutters after the rolling shutter is started is effectively reduced, saving space.

[0024] All electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so this utility model will not explain the control method and circuit connection in detail. At the same time, any parts of this utility model that are not described in detail are all common technologies known to those skilled in the art.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The working principle of the above embodiments is as follows:

[0027] This application arranges the dedicated roller shutter motor 5 inside the roller shutter box 1 and the two roller shutter shafts in a triangular configuration, so that the line connecting the two roller shutter shafts forms a certain angle with the horizontal line, thereby reducing the distance between the two roller shutter panels and ultimately reducing the distance between the two tracks of the roller shutter door, thus saving installation space. Furthermore, by installing a linear sprinkler pipe 403, the linear sprinkler pipe 403 can be connected to a fire hydrant or main sprinkler pipe via a sprinkler pipe 401, and its opening and closing can be controlled by electric valves 402 at both ends. In the event of a fire, when the fireproof roller shutter belt 12 starts to close, the electric valves 402 simultaneously open, and the linear sprinkler system begins to spray. The fireproof roller shutter belt 12 is kept moist with water continuously to maintain its humidity, prevent premature carbonization and toxic smoke production, and ensure that the fireproof roller shutter belt 12 can maintain good fire resistance and achieve high fire resistance. When it is necessary to retract the fireproof roller shutter belt 12, simply start the special roller door motor 5, which will drive the drive sprocket 6 to drive the synchronous chain 8 to rotate the two synchronous sprockets 7, and cause the roller shutter shaft 1 9 and roller shutter shaft 2 10 to start retracting together. The left and right guide rails 11 can limit the two fireproof roller shutter belts 12 to prevent misalignment.

[0028] This application solves the technical problem of the traditional fireproof rolling shutter with 12 rolling door motors, rolling shutter shaft 19, and rolling shutter shaft 210 arranged horizontally, which occupies a lot of space. The special rolling door motor 5, rolling shutter shaft 19, and rolling shutter shaft 210 are arranged in a triangle. The center lines of the two synchronous rolling shafts form an angle with the horizontal line. Utilizing the principle of a right triangle, where the right angle side is smaller than the hypotenuse, the horizontal distance between the two rolling shutters after the rolling shutter is started is effectively reduced, saving space.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0030] 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.
