DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Example 1

[0025] Reference Figure 1-2 A fire extinguishing device for a chemical plant, which is used in the field of fire safety, comprises: a cabinet 1, a cabinet door 2, a U-shaped frame 3, a roller 4, a water hydrant 5, a hand wheel 6 and a plurality of fire extinguishers 7. The cabinet door 2 is hingedly mounted on one side of the cabinet 1, and a water hydrant 5 is arranged inside the cabinet 1 for connecting an external water source, and the water gun can be placed in the cabinet by itself.

[0026] Reference Figure 3 The U-shaped frame 3 is welded inside the cabinet 1, and a slide groove 9 and a limit groove 10 are provided on the U-shaped frame 3. The outer wall of the roller 4 is closely matched with the inner wall of the slide groove 9, and the outer wall of the roller 4 is also provided with a quadrilateral groove 11, which matches the structure in the limit groove 10. The protrusion in the limit groove 10 is inserted into the quadrilateral groove 11 to prevent the roller 4 from falling and to limit the subsequent rotation of the roller 4.

[0027] Reference Figure 4 The hand wheel 6 is composed of a circular plate 16, a clamping rod 17, an eccentric rod 14 and a rotating drum 15. Two clamping rods 17 and an eccentric rod 14 are respectively arranged on both sides of the circular plate 16. The clamping rod 17 matches the clamping groove 13 at one end of the winding roller 4, and the relative position of the hand wheel 6 and the winding roller 4 is fixed by clamping. The eccentric rod 14 is connected to the winding roller 4 through the rotating drum 15. The user can drive the winding roller 4 to rotate by turning the hand wheel 6, so as to retract and release the water hose. The end of the winding roller 4 away from the U-shaped frame 3 is also provided with a clamping groove 12.

[0028] Specifically, the arc frame 3 is at a ninety-degree angle, and the quadrilateral groove 11 is a groove with four equilateral planes on the inner wall. When the water hose is used up, the winding roller 4 is rotated along the arc frame 3 to a flush state. When the quadrilateral groove 11 on the outer wall of the winding roller 4 is located inside the limiting groove 10, it will be constrained by the limiting groove 10 and cannot rotate. When moved to the flush state, the quadrilateral groove 11 is located inside the groove 8, and the winding roller 4 can be rotated at this time. After that, the middle section of the water hose is clamped into the inside of the clamping groove 12, and then the clamping rod 17 on one side of the handwheel 6 is clamped into the clamping groove 13 at one end of the winding roller 4. After that, the handwheel 6 can be rotated to drive the winding roller 4 to rotate, and the water hose is rolled up and stored. When rolling up, the water hose will be squeezed to discharge the water inside. After rolling up, the handwheel 6 is removed and the winding roller 4 is rotated back to its original position. When it is used next time, it can be taken out by the bracket.
