[0018] 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.

[0019] Please see Figure 1-4 A water supply and drainage fire emergency refrigerant coil device includes a mounting recess 1. A rotating shaft 100 is rotatably connected to the groove on the right side of the inner wall of the mounting recess 1 via a bearing. An emergency refrigerant disc 101 is fixedly connected to the left end of the rotating shaft 100. A mounting bracket is installed on the left side of the mounting recess 1. Four mounting holes are provided on the left side of the mounting bracket. The entire device can be fixed to the fire box through the mounting holes.

[0020] An annular plate 11 is fixedly connected to the left side of the emergency tray 101. An annular frame 12 is fixedly connected to the left side of the inner wall of the mounting concave plate 1 and to the surface of the annular plate 11. The inner wall of the annular frame 12 is in rotatable contact with the surface of the annular plate 11. An annular groove 13 is opened on the surface of the annular plate 11. An annular block 14 is fixedly connected to the inner wall of the annular frame 12 and is in rotatable contact with the inner wall of the annular groove 13. By setting the annular plate 11, annular frame 12, annular groove 13 and annular block 14, the stability of the emergency tray 101 during rotation is improved. A coil is wound around the surface of the emergency tray 101. An external water inlet pipe passes through the mounting concave plate 1, annular plate 11 and emergency tray 101 from left to right through a rotary joint and extends into the interior of the emergency tray 101 to connect with the coil.

[0021] A pluggable drive transmission assembly 2 is provided on the mounting recess 1. The drive transmission assembly 2 includes a mounting plate 21, which is located on the top of the inner wall of the mounting recess 1. The top of the mounting plate 21 is in contact with the top of the inner wall of the mounting recess 1. An electric push rod 22 is fixedly connected to the bottom of the mounting plate 21. A recess 23 is fixedly connected to the bottom end of the electric push rod 22. A servo motor 24 is fixedly connected to the bottom of the inner wall of the recess 23. Fixed shafts 25 are rotatably connected to the left and right grooves of the inner wall of the recess 23 through bearings. Movable wheels 26 are fixedly connected to the fixed shafts 25. The two movable wheels 26 are fixedly connected to each other through a transmission shaft 27. Transmission wheels 28 are fixedly connected to the surface of the output shaft of the servo motor 24 and the surface of the transmission shaft 27. The surfaces of the two transmission wheels 28 are connected by a belt 29.

[0022] A controller is fixedly connected to the top left side of the inner wall of the recess 23, and a battery is fixedly connected to the top right side of the inner wall of the recess 23. The servo motor 24 is electrically connected to the controller, and the battery provides power to it.

[0023] Both sides of the surface of the emergency tray 101 are fixedly connected with annular rubber blocks 10. By setting the annular rubber blocks 10, the friction generated when in contact with the moving wheel 26 is increased, ensuring the stability of the emergency tray 101 when the moving wheel 26 drives the emergency tray 101 to rotate through the annular rubber blocks 10.

[0024] Positioning rods 4 are fixedly connected to the left and right sides of the top of the concave block 23. Positioning blocks 5 are slidably connected to the surface of the positioning rods 4. The top of the positioning blocks 5 is fixedly connected to the bottom of the mounting plate 21. By setting the positioning rods 4 and the positioning blocks 5, the stability of the concave block 23 when moving up and down is improved.

[0025] The drive transmission assembly 2 is connected to the mounting recess 1 by a limiting and fixing assembly 3. The limiting and fixing assembly 3 includes two limiting blocks 31, which are respectively installed on the top of the mounting plate 21. A limiting groove 32 is opened at the bottom of the front of the mounting recess 1 and at the position corresponding to the limiting block 31. The top of the limiting block 31 passes through the limiting groove 32 and extends into it, contacting the inner wall of the limiting groove 32. The limiting and fixing assembly 3 also includes a pull plate 300, which is set at the top of the mounting recess 1. The bottom of the pull plate 300 contacts the top of the mounting recess 1. An insert block 33 is fixedly connected to the bottom of the pull plate 300 at the position corresponding to the limiting block 31. A slot 34 is opened at the top of the limiting block 31 at the position corresponding to the insert block 33. The bottom of the insert block 33 passes through the limiting groove 32 and the slot 34 from top to bottom and extends into the inside of the slot 34, contacting the inner wall of the slot 34.

[0026] The top of the mounting recess 1 is provided with a fixing groove 6, and a movable iron block 7 is provided inside the fixing groove 6. The surface of the iron block 7 slides in contact with the inner wall of the fixing groove 6. The top of the iron block 7 is fixedly connected to the bottom of the pull plate 300 through the connecting block 8. A magnet 9 that attracts the iron block 7 is fixedly connected to the bottom of the inner wall of the fixing groove 6. By setting the fixing groove 6, the iron block 7, the connecting block 8 and the magnet 9, the stability of the insert 33 inserted into the slot 34 is improved, thereby ensuring the stability of the limit block 31 inserted into the limit groove 32.

[0027] When it is necessary to remove the drive transmission assembly 2 from the mounting recess 1, first pull the pull plate 300 upward. The pull plate 300 drives the iron block 7 to separate from the magnet 9 through the connecting block 8. The pull plate 300 drives the insert block 33 to move upward, so that the insert block 33 separates from the slot 34. Then pull the recess 23 forward. The recess 23 drives the limiting block 31 to move forward through the mounting plate 21, so that the limiting block 31 separates from the limiting groove 32, thus completing the disassembly.

[0028] By cooperating with the electric push rod 22 of the drive transmission assembly 2 and the servo motor 24, the emergency rewinding of the emergency rewinding disc 101 can be realized, avoiding the need for manual rewinding, improving rewinding efficiency and reducing labor. The moving wheel 26 rotates synchronously through the transmission shaft 27, and with the constant speed control of the servo motor 24, the disc is subjected to uniform force during the rewinding process, avoiding local compression caused by manual winding. By setting the limit fixing assembly 3, the drive transmission assembly 2 can be removed from the mounting recess 1 for maintenance and repair, improving the flexibility of use.

[0029] When in use, when an emergency water supply is needed, simply pull the water outlet at the bottom of the coil. The emergency coil 101 will rotate and unfold the coil via the rotating shaft 100. The cooperation between the annular plate 11 and the annular frame 12 ensures a smooth unfolding process.

[0030] After use, activate the electric push rod 22 to lower it, causing the concave block 23 to move downwards along the positioning rod 4 until the moving wheel 26 contacts the annular rubber blocks 10 on both sides of the emergency tray 101. Then, activate the servo motor 24 via the controller. Its output shaft drives the transmission shaft 27 to rotate through the transmission wheel 28 and belt 29, causing the left and right moving wheels 26 to rotate synchronously. Through friction, the emergency tray 101 is driven to wind up the coil. The servo motor 24 runs at a constant speed of 15 revolutions per minute, which, together with the synchronous transmission of the moving wheels 26, ensures that the coil is wound evenly.
