Description

Technical Field

[0001] The utility model relates to the field of firefighting and rescue, in particular to a non-powered mobile water cannon bracket which utilizes water weight for stabilization and water pressure for lifting and lowering. Background Art

[0002] Firefighters using water cannons at fire scenes require them to be lightweight, flexible in angle adjustment, and able to maintain balance under the pressure of high-pressure water. Existing mobile water cannons at fire scenes are typically fixed to the ground via brackets, with limited firing angles and directions. This is particularly cumbersome when multiple fire sources are involved, requiring relocation, angle adjustment, and direction adjustments. Changing angles requires the coordinated efforts of multiple personnel, which is time-consuming and labor-intensive, potentially delaying the intended target. Furthermore, existing water cannons, due to inherent design flaws, cannot meet the requirements for spraying at all angles. Water cannons that can be raised and rotated are only found on the tops of fire trucks. These cannons maintain balance through the weight of the fire truck, but many locations are inaccessible to fire trucks. To more effectively extinguish fires on site, firefighters urgently need a lightweight, mobile water cannon that can be quickly set up, has a stable chassis, can be flexibly raised and lowered, and can rotate 360 ​​degrees. We have also retrieved a utility model with patent announcement number: CN218187640U, which discloses an adjustable emergency fire water cannon, which is stable through the weight of the chassis, and its disclosed telescopic method is powered. In actual use, due to the heavy overall structure, it requires multiple people to carry it together to achieve transfer. Utility Model Content

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

[0025] like Figure 1 、 Figure 2 As shown, the utility model proposes a non-powered mobile water cannon bracket that utilizes water weight for stability and water pressure for lifting and lowering, comprising a box body 1. The box body 1 can be made of a rigid material or a soft rubber material or an elastic water bag. When the box body 1 is not filled with water, it is light in weight and easy to carry. A shoulder strap can be provided on the box body 1 to facilitate the user to carry it on his back. A rolling and telescopic rod can be provided at the bottom, and the telescopic rod can be pulled out as a bracket to further enhance the stability of the water tank.

[0026] The box body 1 is provided with a water tank inlet end 5 and a water hose inlet end 6, and is connected to a high-pressure water pump through a tee. A first opening and closing valve 7 is connected between the water pump and the water tank inlet end 5, and a second opening and closing valve 8 is connected between the water pump and the water hose inlet end 6. The first opening and closing valve 7 is used to inject water into the box body 1, and the second opening and closing valve 8 controls the water inlet to the water hose 3. The water hose inlet end 6 is connected to the box body 1 and is connected to the built-in unpowered telescopic component 2. Specifically:

[0027] The end of the telescopic component 2 in the box body 1 extends out of the top of the box body 1 when it is retracted. In order to facilitate transportation, the end of the retractable component is as close to the top of the box body 1 as possible. The telescopic component 2 includes a plurality of concentrically nested sleeves 9. The number of sleeves 9 is not limited and can be set according to the actual height required, such as Figure 3As shown, a limiting ring 10 is provided on the inner side of the top opening of the sleeve 9, and a retaining ring 11 is provided on the bottom of the sleeve 9, protruding from the outer wall of the sleeve 9. When the sleeve 9 of the telescopic assembly 2 is extended, the retaining ring 11 of the adjacent sleeve 9 is pressed on the limiting ring 10. The side wall of the sleeve 9 is provided with a pin hole 12, and a pin is passed through the pin hole 12. The pin is used to pass through the pin hole 12 to limit the extension of the sleeve 9 when the device is not in use. This embodiment only lists one structure of the telescopic assembly 2. The side wall of the sleeve 9 can also be tapered. When telescoping, due to the large bottom diameter, it can be extended and limited.

[0028] The innermost casing 9 of the telescopic assembly 2 houses a water hose 3. The water hose 3 is a high-pressure hose. The water inlet 6 of the water tank passes through the water tank and the outermost casing 9 of the telescopic assembly 2. The outermost casing 9 of the telescopic assembly 2 has a hole at the bottom, allowing the water hose inlet 6 to connect to the internal water hose 3. The water hose inlet 6 and the water tank inlet 5 are connected to a three-way valve and are connected to a remote high-pressure fire water source. Water is used as the fire extinguishing agent, although other liquid fire extinguishing agents can also be connected externally. The end of the water hose 3 extends out of the telescopic assembly 2. The innermost casing is secured with a flange or quick-release connector for securing a water monitor 4. The structure of the water monitor 4 is conventional and will not be repeated in this embodiment. When the water hose 3 is filled with water, it swells, driving the telescopic assembly 2 to extend. The unpowered design means that the telescopic assembly 2 is not raised or lowered by external electric or pneumatic means, reducing the weight of the entire device. After the fire is extinguished, the second water inlet valve 8 reduces the water pressure, and the telescopic component 2 will be retracted without the water hose 3 pushing it. It can also be retracted by external downward pressure by manpower. The sleeves 9 can rotate with each other, and the user can rotate the sleeves 9 to achieve 360° rotation.

[0029] like Figure 4 As shown, in order to ensure that the telescopic assembly 2 contracts more smoothly, a tension spring 13 can be set at the bottom of the innermost sleeve 9 of the telescopic assembly 2 to assist the telescopic assembly 2 to be retracted into the box body 1 through the tension spring 13.

[0030] Another embodiment of the connection between the telescopic assembly 2 and the box body 1 is as follows:

[0031] A sealing ring can be provided at the position where the telescopic component 2 extends out of the box body 1 to ensure water tightness. A water cannon 4 is connected to the top of the telescopic sleeve. The telescopic component 2 includes a plurality of concentrically nested sleeves 9. The number of sleeves 9 is not limited and is set according to actual height requirements. A limiting ring 10 is provided on the inner side of the top mouth of the sleeve 9, and a retaining ring 11 protruding from the outer wall of the sleeve 9 is provided at the bottom of the sleeve 9. When the sleeve 9 of the telescopic component 2 is extended, the retaining ring 11 of the adjacent sleeve 9 is pressed on the limiting ring 10, and a sealing ring is provided between the adjacent sleeves 9 to ensure the sealing of the sleeve 9 when it is extended and retracted. In this embodiment, a water hose 3 may not be provided. After water is poured into the water tank, the water pressure will push the telescopic sleeve out and water will flow into the water cannon 4.

[0032] To use this device, the mobile water monitor 4 is secured to the bracket and ready for use. In the event of a fire, firefighters carrying the mobile water monitor 4 with the bracket arrive at the scene, place the water tank on the ground, connect the water source tee to a remotely supplied high-pressure firefighting water or liquid fire extinguishing agent, open the first on-off valve 7, and first fill the chassis with water. The weight of the chassis ensures the balance and stability of the entire bracket and the water monitor 4. The second on-off valve 8 is then opened to pump water into the hose 3, which then supplies water to the upper connected water monitor 4 for firefighting operations. During the firefighting operation, firefighters can adjust the water pressure within the hose 3 by adjusting the second on-off valve 8 to raise or lower the telescopic assembly 2 as needed. After reaching the desired position, firefighters secure the telescopic assembly 2 with the positioning pins and continue firefighting operations. After the firefighting operation is completed, the plug on the side of the water tank is opened to drain the water completely, making the bracket lighter and allowing it to be easily carried away.

[0033] In addition, for some places that are inconvenient for human access, remote control operation can be achieved by remotely controlling the drive device at the bottom of the water tank. The equipment can also be further deployed with an AI-based artificial intelligence and FSD automatic driving system to realize the fully intelligent search for fire sources and automatic fire extinguishing operations of this device.

[0034] Another embodiment proposed by the present application is as follows: Figure 6 As shown, it includes a water tank 1, and a telescopic component 2 is arranged on the upper part of the water tank 1. Different from the previous embodiment, the telescopic component 2 of this embodiment protrudes from the top of the water tank, the outermost sleeve 9 of the telescopic component 2 is fixed on the top of the water tank 1, and the water hose 3 is arranged in the telescopic component 2, and the bottom of the bottom sleeve 9 has a hole, the water hose 3 is connected to the opening and is connected to the water tank 1 through a connecting pipe 15 and a third opening and closing valve 14. A water tank water inlet end 5 is provided on the water tank 1 to directly connect to an external water source interface, and the water pressure in the water hose is adjusted by opening and closing the third opening and closing valve 14.
