[0004] An existing fire hose cannot adjust the water pressure during use. During use, the water pressure is often high and low, and the minimum value of the fire-fighting water pressure cannot be ensured, which is not conducive to fire extinguishing, wastes water resources, and reduces fire-fighting efficiency.

[0005] Therefore, in view of the above problems, an intelligent pressure-regulating fire hose is proposed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model is spirally connected together by a first connecting sleeve and a second connecting sleeve. Because one side of the limit block is fixedly connected to the limit column, the limit column is fixedly connected to the circular groove inside the support block, the support block is fixedly connected to the inner wall of the second connecting block, and the pressure stabilizing block is sleeved on the outside of the limit column.

DETAILED DESCRIPTION

[0024] 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.

[0025] like Figures 1 to 5 As shown, the utility model provides an intelligent pressure-regulating fire hose, including a first hose 1, one end of the first hose 1 is fixedly connected with a first connecting sleeve 2, the interior of the first connecting sleeve 2 is spirally connected with a second connecting sleeve 3, the inner wall of the second connecting sleeve 3 is fixedly connected with a support block 4, a circular groove 5 is opened inside the support block 4, the interior of the circular groove 5 is fixedly connected with a limiting column 6, the outer side of the limiting column 6 is sleeved with a first spring 9, one end of the first spring 9 is attached with a pressure stabilizing block 8, and one end of the limiting column 6 is fixedly connected to the limiting block 7.

[0026] Specifically, the outer side of the second connecting sleeve 3 is fixedly connected to the second water hose 10, the interior of the second water hose 10 is interspersed with a water gun head 11, the interior of the water gun head 11 is provided with a groove 21, the outer side of the water gun head 11 is provided with a rotating sleeve 12, the interior of the rotating sleeve 12 is slidably connected to a push rod 14, the bottom end of the push rod 14 is fixedly connected to a semicircular ring 15, and the side surface of the semicircular ring 15 fits with the inner wall of the groove 21.

[0027] Furthermore, a gasket 17 is embedded inside the first connecting sleeve 2. The gasket 17 is made of waterproof rubber, which makes the first connecting sleeve 2 and the second connecting sleeve 3 more tightly connected to prevent water leakage caused by excessive water pressure.

[0028] Furthermore, the bottom end of the limit block 7 is fixedly connected to the top end of the voltage stabilizing block 8, and the cross-sectional area of ​​the limit block 7 and the voltage stabilizing block 8 after being fitted together is circular, which can effectively block the water outlet of the first water hose 1 to prevent water overflow.

[0029] It is worth mentioning that a diverter pipe 18 is inserted and connected inside the second connecting sleeve 3, and a valve stem 19 is spirally connected inside the diverter pipe 18. When the water pressure is too high, the valve stem 19 can be rotated to allow part of the water to flow out through the diverter pipe 18, thereby reducing the pressure of the water on the connecting sleeve and the water hose, preventing the water hose from being damaged by excessive pressure and reducing losses.

[0030] It is worth noting that a rotation groove 13 is opened inside the rotating sleeve 12, and the depth of the rotation groove 13 decreases successively around the central axis of the rotating sleeve 12, so that the push rod 14 can rotate stably when rotating inside the rotation groove 13, and the cross-sectional area of ​​the water outlet of the water gun head 11 can be adjusted.

[0031] It is worth mentioning that a second spring 16 is sleeved on the outer side of the push rod 14, and the end face of the second spring 16 is in contact with the inner wall of the rotating groove 13. The second spring 16 can apply pressure to the push rod 14 to prevent the push rod 14 from suddenly falling out of the rotating groove 13 when sliding, which is not conducive to the regulation of water pressure.

[0032] It is worth emphasizing that the second water hose 10 is fixedly connected to the inside with a waterproof layer 20. The material of the second water hose 10 is polyamide fiber. Polyamide fiber has high strength, high toughness and durability, and can withstand long-term external forces and environmental influences. The material of the waterproof layer 20 is polyester fiber. Polyester fiber can prevent water and moisture from penetrating into the second water hose 10, thereby increasing the service life of the water hose.

[0033] Working principle and process:

[0034] When the user needs to use the fire hose to extinguish a fire, he first uses the first connecting sleeve 2 to spirally connect the second connecting sleeve 3 together, and connects the first water hose 1 and the second water hose 10 fixedly connected thereto together. Under the action of the gasket 17, the first connecting sleeve 2 and the second connecting sleeve 3 are connected more tightly to prevent water leakage caused by excessive water pressure. Because one side of the limit block 7 is fixedly connected to the limit column 6, the limit column 6 is fixedly connected to the circular groove 5 inside the support block 4, the support block 4 is fixedly connected to the inner wall of the second connecting sleeve 3, and the pressure stabilizing block 8 is sleeved on the outside of the limit column 6. When water flows through the first water hose 1, the water flow applies pressure to the limit block 7 and the pressure stabilizing block 8, causing the pressure stabilizing block 8 to slide on the outside of the limit column 6 to allow water to flow through. Under the action of the first spring 9, the force pushing the pressure stabilizing block 8 open is fixed, thereby ensuring the minimum water pressure for fire extinguishing when the water flows through, and no water pressure occurs. When the water pressure is too high, the valve stem 19 can be rotated to make part of the water flow out through the diversion pipe 18, thereby reducing the pressure of the water flow on the connecting sleeve and the water hose, preventing the water hose from being damaged by excessive pressure, and reducing losses. The water flow then flows out through the second water hose 10. When the water pressure is insufficient or too high, the rotating sleeve 12 arranged on the outside of the water gun head 11 can be rotated so that the rotating sleeve 12 squeezes the push rod 14 under the action of the second spring 16, so that the push rod 14 rotates inside the rotating groove 13 and slides toward the inside of the water gun head 11, driving the semicircular ring 15 fixedly connected to the bottom end of the push rod 14 to slide inside the groove 21 and gradually slide out of the groove 21. The semicircular ring 15 reduces the cross-sectional area of ​​the water outlet of the water gun head 11, thereby realizing the change of water pressure, which is convenient for adjusting to different internal water pressures when dealing with fires in different situations.
