[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 , Figure 2 As shown, the present invention proposes a water cannon support, including...

[0026] The supporting box 1 can be circular, polygonal, or any other shape, and the shape of the water bladder is not limited. The examples listed in this embodiment are as follows: Figure 3 As shown, the support box 1 is a frustum-shaped body. A passage cavity 20 is vertically arranged in the center of the frustum-shaped body. The water inside the passage cavity 20 is separated from the water inside the support box 1. A water inlet pipe 2 passes through the support box 1. The two ends of the water inlet pipe 2 are rigid pipes, and a section of flexible hose is provided in the middle for easy bending. The water inlet pipe 2 passes through the passage cavity 20 from the bottom of the support box 1 to the top of the support box 1 and is connected to a telescopic pipe 3. A water cannon 4 is connected to the telescopic pipe 3. A valve body 5 is provided between the telescopic pipe 3 and the water inlet pipe 2. The connection between the telescopic pipe 3 and the water inlet pipe 2 is made by a butterfly valve and a flange. The water pressure is adjusted by controlling the butterfly valve to realize the raising and lowering of the telescopic pipe.

[0027] An opening 7 is provided on the side of the water inlet pipe 2 at the upper part of the support box 1. A rigid pipe 21 is connected to the side of the water inlet pipe 2 near the lower side of the telescopic butterfly valve. A control valve 19 is provided on the rigid pipe 21, with the end of the rigid pipe 21 pointing towards the opening 7. This valve controls the amount of water injected into the support box 1 from the water inlet pipe 2, allowing the support box 1 to be stabilized by its own weight. After the water injection is complete, the control valve 19 is closed. After the fire extinguishing operation is completed, the drain end 22 can be opened to drain the water from the support box 1, emptying the support box 1 and allowing the support box 1 and its 6 supporting legs to be quickly folded and stored.

[0028] To increase the stability of the support box 1 and facilitate the entry of the water inlet pipe 2 from the bottom of the support box 1, multiple support feet 6 are arranged in a circular pattern on the lower part of the valve body 5. In this embodiment, four sets of support feet 6 are selected. The support feet 6 extend along the outer wall of the support box 1 onto the ground, supporting the support box 1. The support box 1 is at a certain distance from the ground, which also facilitates the entry of the water inlet pipe 2 from the bottom of the support box 1. A mounting seat 9 is provided on the flange at the lower part of the valve body 5. One end of the support foot 6 is provided with a hole. A pin passes through the hole and is connected to the mounting seat 9, so that the support foot 6 can rotate along the pin. When the water bag is stored, the support feet 6 can be gathered together and the water bag can be sandwiched in the middle for storage.

[0029] To ensure better stable support for the support foot 6, a protruding sleeve 8 is provided on the surface of the support box 1. The support foot 6 passes through the protruding sleeve 8, so that the support foot 6 and the water bag are stably matched.

[0030] In this embodiment, a telescopic tube 3 is specially provided to increase the height of the water cannon 4 during operation, such as... Figure 4 As shown, the telescopic tube 3 includes an outer tube 11 and an inner tube 10. The opening of the outer tube 11 is provided with a first sealing ring 12, and the end of the inner tube 10 that extends into the outer tube 11 is provided with a second sealing ring 13.

[0031] The inner tube 10 rises until the second sealing ring 13 presses against the first sealing ring 12. The connection between the telescopic tube 3 and the inlet of the water pipe 2 is via a flange. The inner tube 10 of the telescopic tube 3 is sealed by the first sealing ring 12 and the second sealing ring 13. The operator controls the water pressure inside the telescopic tube by adjusting the valve body 5. After water enters the telescopic tube 3 through the inlet pipe 2, the inner tube rises or falls due to the increase or decrease in water pressure inside the telescopic tube. The operator fixes the lifting height of the telescopic tube using the chain 18 according to the actual required height.

[0032] Water enters the water cannon 4 through the telescopic pipe, and the operator uses the control valve on the water cannon 4 to spray and extinguish the fire.

[0033] In addition, to ensure that the inner tube 10 and the outer tube 11 can slide when not in use, a limiting device 14 is provided between the inner tube 10 and the outer tube 11. The limiting device 14 includes a first piece 15 connected to the inner tube 10 and a second piece 16 located on the outer tube 11. The second piece 16 has a through hole, and a chain 18 is connected to the first piece 15. The chain 18 passes through the through hole, and a locking pin 17 is provided on the through hole. In the retracted state, the chain 18 is locked by the locking pin 17, thereby pulling the inner tube 10 and the outer tube 11 together.

[0034] When using this water cannon bracket, the support legs 6 are opened to support the ground in all directions. Water is then poured into the support box 1 to increase gravity and further stabilize the entire bracket. After water or fire extinguishing liquid is introduced into the water inlet pipe 2, the direction of the water cannon 4 can be adjusted to extinguish the fire.
