Description

Technical Field

[0001] This utility model belongs to the field of sprinkler switch technology, and specifically relates to an automatic sprinkler switch. Background Technology

[0002] In the field of modern building and industrial automation, sprinkler systems are one of the important safety facilities used for fire prevention and control. The normal operation of sprinkler systems depends on the precise coordination of various components. Among them, the sprinkler automation switch is the core component, responsible for automatically activating the sprinkler system when a fire is detected. Existing sprinkler automation switches typically include a switch body and wires connected to it. These wires are used to connect sensors, alarm devices, and other control units.

[0003] However, existing automatic sprinkler switches have some limitations. First, due to the limitations of the installation environment, the switch body and wire plug may not be able to find a suitable place for installation. This usually occurs when space is limited or other equipment has already occupied the ideal installation position. Second, the wire length is fixed and cannot be adjusted, which may cause the wire to droop or become tangled with other wires during installation. This not only affects the aesthetics of the sprinkler system, but may also cause potential interference to the normal operation of the system.

[0004] Therefore, there is an urgent need for a new type of automatic sprinkler switch. Utility Model Content

[0005] The purpose of this invention is to provide an automated sprinkler switch that can not only automatically adjust the length of the wire to adapt to different installation environments, but also effectively avoid the problems of drooping and tangling of the wire, thereby improving the installation flexibility and reliability of the sprinkler system.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An automatic sprinkler switch includes a sealed box, inside which a receiver is placed. A wire is mounted on the receiver, and the end of the wire away from the receiver passes through the sealed box and is connected to an electric motor. A ball valve is installed on the output end of the electric motor.

[0008] An installation box is mounted on the outside of the wire, and a winding structure is provided inside the installation box for winding the wire.

[0009] The winding structure includes a rotating ring rotatably connected inside the mounting box. Both ends of the rotating ring are symmetrically provided with slots. The middle part of the wire passes through the slot. A rotating rod is fixed to the top of the slot. The top of the rotating rod passes through the mounting box and extends to the outside of the mounting box.

[0010] Inside the mounting box, on both sides of the rotating ring, there are guide structures for guiding the wire to the position where it is wound around the outside of the rotating ring.

[0011] The guide structure includes a bidirectional screw rotatably connected inside the mounting box, a movable block threadedly connected to the outer side of the bidirectional screw, a slider fixed to the side of the movable block near the mounting box, and the slider slidably connected to the inner wall of the mounting box, and the wire passing through the movable block;

[0012] The mounting box contains a drive mechanism, which is used to drive the bidirectional screw to rotate.

[0013] The drive mechanism includes a drive gear rotatably connected to the outside of the rotating rod, driven gears meshing with both sides of the drive gear, and the driven gears rotatably connected to the mounting box. A following rotating gear is fixed to the outside of the bidirectional screw, and the following rotating gear meshes with the driven gear.

[0014] The top of the mounting box is fixed with a mounting shell. The rotating rod passes through the mounting shell and extends to the top of the mounting shell. A pull rod is slidably connected inside the mounting shell. A limiting arc strip is fixed to one end of the pull rod near the rotating rod. A spring is installed between the limiting arc strip and the inner wall of the mounting shell and on the outside of the pull rod.

[0015] The driving gear and the following rotating gear have the same diameter.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention can not only automatically adjust the length of the wire to adapt to different installation environments, but also effectively avoid the problems of wire drooping and tangling, thereby improving the installation flexibility and reliability of the sprinkler system.

[0027] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0028] like Figures 1-7 As shown, an automated sprinkler switch includes a sealed box 1, inside which a receiver 2 is placed. The sealed box 1 is covered to seal the receiver 2, providing waterproof and moisture-proof protection. A wire 3 is mounted on the receiver 2, with the end of the wire 3 away from the receiver 2 passing through the sealed box 1 and connected to an electric motor 4. A ball valve 5 is installed on the output end of the electric motor 4, which can be installed on the sprinkler pipe to control the sprinkler pipe. The receiver 2 is also connected to a wire 3, which is connected to a 220V power supply to power the receiver 2. The receiver 2 is equipped with a structure for electrical connection to a mobile phone. This structure can be a QR code, which allows the user to scan and download the corresponding APP. The APP controls the receiver 2, the electric motor 4, the opening and closing of the ball valve 5, and when the electric motor 4 starts and stops, etc.

[0029] An installation box 6 is installed on the outside of the conductor 3. The installation box 6 is equipped with a winding structure for winding the conductor 3.

[0030] See attached document Figures 3-5The winding structure includes a rotating ring 7 rotatably connected inside the mounting box 6. Both ends of the rotating ring 7 are symmetrically provided with slots 8. The middle part of the wire 3 passes through the slot 8. A rotating rod 11 is fixed to the top of the slot 8. The top of the rotating rod 11 passes through the mounting box 6 and extends to the outside of the mounting box 6. A rotating handle is fixed to the top of the rotating rod 11. The rotating rod 11 can be rotated more conveniently through the rotating handle.

[0031] In use, since the wire 3 is inside the slot 8, rotating the rotating rod 11 will drive the rotating ring 7 to rotate, and rotating the pulling rod 17 will allow the wire 3 to be wound around the outside of the rotating ring 7, thereby allowing the wire 3 to be unwound and retracted. The purpose is that after the ball valve 5 is installed on the spray pipe, if there is no suitable location nearby to install the sealing box 1 and the receiver 2, the wire 3 can be loosened to extend the wire 3, so that the sealing box 1 can be installed at a farther location. If the sealing box 1 is installed close to the ball valve 5, the wire 3 can be wound up to shorten the wire 3 as a whole, so as to prevent the wire 3 from drooping and getting tangled with other wires.

[0032] Inside the mounting box 6 and on both sides of the rotating ring 7, there are guide structures. The guide structures are used to guide the wire 3 to be wound around the outside of the rotating ring 7.

[0033] See attached document Figure 3 and attached Figure 4 The guide structure includes a bidirectional screw 9 rotatably connected inside the mounting box 6. The threads of the two bidirectional screws 9 are opposite, which causes the two moving blocks 19 to move in opposite directions. A plate is provided on the inner wall of the mounting box 6. The bidirectional screw 9 can be rotatably connected to the mounting box 6 through the plate. The moving block 19 is threadedly connected to the outer side of the bidirectional screw 9. A slider 10 is fixed on the side of the moving block 19 near the mounting box 6. A sliding groove is provided on the inner wall of the mounting box 6, and the slider 10 is slidably connected to the inner wall of the mounting box 6 through the sliding groove. A hole is provided on the moving block 19, and the wire 3 passes through the moving block 19.

[0034] The mounting box 6 contains a drive mechanism, which is used to drive the bidirectional screw 9 to rotate.

[0035] When the rotating ring 7 is rotated by the rotating rod 11, the bidirectional screw 9 can be driven to rotate by the drive mechanism. Then, through the threaded connection between the bidirectional screw 9 and the moving block 19, and the sliding connection between the moving block 19 and the mounting box 6 through the slider 10, the moving block 19 can slide up and down on the outside of the bidirectional screw 9. Due to the characteristics of the bidirectional screw 9, the moving block 19 can automatically slide towards the bottom after moving to the top of the bidirectional screw 9, and automatically slide towards the top after moving to the bottom of the bidirectional screw 9. Through this setting, the wire 3 can be wound in a regular manner on the outside of the rotating ring 7, avoiding the wire 3 from always being wound in the same position on the rotating ring 7.

[0036] See attached document Figure 4 The drive mechanism includes a drive gear 12 rotatably connected to the outside of the rotating rod 11. Both sides of the drive gear 12 are meshed with driven gears 13, and the driven gears 13 are rotatably connected to the mounting box 6. A follower rotating gear 14 is fixed to the outside of the bidirectional screw 9. Furthermore, the drive gear 12 and the follower rotating gear 14 have the same diameter. With this arrangement, the rotating ring 7 can rotate synchronously with the bidirectional screw 9, thereby driving the slider 10 to move synchronously with the rotating ring 7. The follower rotating gear 14 is meshed with the driven gear 13.

[0037] When the rotating rod 11 is rotated, the driving gear 12 can be driven to rotate. Through the meshing connection between the driving gear 12 and the driven gear 13, the driving gear 12 drives the driven gear 13 to rotate. Through the meshing connection between the driven gear 13 and the following rotating gear 14, the driven gear 13 can drive the following rotating gear 14 to rotate, thereby driving the bidirectional screw 9 to rotate.

[0038] See attached document Figure 7 The top of the mounting box 6 is fixed with a mounting shell 15. The rotating rod 11 passes through the mounting shell 15 and extends to the top of the mounting shell 15. A pull rod 17 is slidably connected inside the mounting shell 15. A limiting arc strip 16 is fixed at one end of the pull rod 17 near the rotating rod 11. A spring 18 is installed between the limiting arc strip 16 and the inner wall of the mounting shell 15 and on the outside of the pull rod 17. When rotating the rotating rod 11, the pull rod 17 can be pulled first, so that the limiting arc strip 16 does not contact the rotating rod 11. At this time, the rotating rod 11 can be rotated.

[0039] After the rotation is completed, the pull rod 17 is released, causing the spring 18 to spring the limiting arc strip 16 toward the rotating rod 11 and abut against it. At this time, the limiting arc strip 16 can restrict the rotating rod 11 through friction. The inner wall of the limiting arc strip 16 and the outer side of the rotating rod 11 are provided with anti-slip textures to further increase its friction.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
