[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-6 A quick-install coal yard fire cannon shown in the figure includes a barrel 1, one end of the barrel 1 is provided with a control box 2 for rotating the barrel 1, the top of the control box 2 is provided with a lower connecting flange 4 and an upper connecting flange 5 for connecting a water pipe, the bottom end of the lower connecting flange 4 is provided with a connecting assembly for connecting the lower connecting flange 4 and the upper connecting flange 5, the connecting assembly includes a connecting part and a hinged part, the connecting part includes a connecting screw 6, the outer wall of the connecting screw 6 is provided with a connecting nut 7, and the interior of the lower connecting flange 4 is provided with a blocking assembly for limiting the movement of the connecting nut 7.

[0023] Specifically, a connecting pipe 3 for connecting with a lower connecting flange 4 is fixedly connected to the top of the control box 2 .

[0024] Furthermore, the barrel 1, the control box 2 and the connecting pipe 3 constitute an existing model PSKD20-CV fixed fire cannon, which is connected to the water pipe through the connecting pipe 3 to supply water to the barrel 1. The rotation of the barrel 1 is controlled by the control box 2 to achieve water spraying and fire extinguishing at the fire point in the coal yard.

[0025] Specifically, the outer walls of the lower connecting flange 4 and the upper connecting flange 5 are respectively provided with insertion grooves for inserting the connecting screw 6, and the connecting nut 7 is threadedly sleeved on the outer wall of the connecting screw 6. The hinge includes symmetrically arranged fixing blocks 8, and the bottom of the connecting screw 6 is arranged on the opposite side of the two fixing blocks 8. The top of the fixing block 8 is fixedly connected to the bottom end of the lower connecting flange 4. A circular through groove is provided at the bottom of the connecting screw 6, and a circular hole is provided on one side of the fixing block 8. Round rods are interspersed and connected inside the circular hole and the circular through groove.

[0026] Furthermore, the insertion groove runs through the outer walls of the lower connecting flange 4 and the upper connecting flange 5, so that it is convenient for the connecting screw 6 to rotate into the inside of the insertion groove. At least three insertion grooves are provided at the top of the lower connecting flange 4, and the three insertion grooves are arranged in a ring with equal intervals. The insertion groove of the upper connecting flange 5 is provided corresponding to the insertion groove of the lower connecting flange 4, and the number of the connecting screws 6 corresponds to the number of the insertion grooves of the lower connecting flange 4. Two fixing blocks 8 are symmetrically arranged on both sides of the bottom of the connecting screw 6. The inner wall of the circular through groove is a smooth inner wall through the round rod and the inner wall of the circular hole of the fixing block 8, and the size is 0.7 times the diameter of the connecting screw 6, so that the connecting screw 6 can be rotated with the round rod as the center. When the connecting screw 6 is rotated into the insertion grooves of the lower connecting flange 4 and the upper connecting flange 5, the connecting nut 7 can be squeezed against the upper connecting flange 5 by rotating the connecting nut 7 threadedly sleeved on the outer wall of the connecting screw 6, thereby completing the fixed connection between the lower connecting flange 4 and the upper connecting flange 5.

[0027] Specifically, an annular cavity is opened inside the lower connecting flange 4, and the blocking assembly includes a blocking plate 10 and a rotating ring 9. The rotating ring 9 is connected to the annular cavity through an interlacing connection, one end of the blocking plate 10 is fixedly connected to the outer wall of the rotating ring 9, and a movable groove for moving the blocking plate 10 is opened on one side of the annular cavity, and one end of the movable groove passes through one end of the insertion groove.

[0028] The locking nut 7 is locked to the locking nut 7, and the locking nut 7 is locked to the locking nut 7. The locking nut 7 is locked to the locking nut 7, and the locking nut 7 is locked to the locking nut 7.

[0029] Therefore, the connecting screw 6 is connected to the lower connecting flange 4 by the fixing block 8, so that the connection screw 6 can be prevented from being lost. Therefore, when climbing up to repair the fire monitor and disassembling the lower connecting flange 4 and the upper connecting flange 5, there is no need to worry about the missing of the connecting screw 6, and it can be installed and disassembled quickly. At the same time, under the action of the blocking plate 10, the rotating connecting screw 6 will not move at will in the insertion groove, so that the rotation of the connecting nut 7 is stable, and the connecting screw 6 does not need to be held by hand, thereby saving the installation time of the connecting screw 6 and the connecting nut 7.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
