Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a mobile fire monitor. Background Technology

[0002] Fire monitors are fire extinguishing devices that use water as a medium to extinguish fires from a distance. They are suitable for petrochemical enterprises, tank farms, aircraft hangars, warehouses, ports, garages, and other places. They are also ideal vehicle-mounted fire monitors for fire trucks. Traditional fixed fire monitors are installed on buildings or fire trucks and rely on fixed water supply networks or large fire trucks. Their movement and deployment are limited. In special scenarios such as narrow streets in urban and rural areas, trade markets, construction sites, or inside large venues, large fire trucks have difficulty entering, and fixed monitors cannot cover the area, resulting in blind spots in fire extinguishing.

[0003] The "Mobile Fire Monitor" disclosed in application number "201620426668.7" includes a fire monitor body, a connecting bend, a monitor head, and a movable base. The fire monitor body, connecting bend, and monitor head are connected in sequence. The fire monitor body is fixed on the movable base. The fire monitor body is provided with a hose interface. The connecting bend is horizontally rotatable and connected to the fire monitor body. The monitor head is vertically rotatable and connected to the connecting bend. The movable base has wheels at the front end and a stand and a push-pull rod at the rear end. This utility model has a simple structure, is easy to move, and has good mobility, effectively solving the problem that existing mobile fire monitors cannot be moved to the predetermined position or withdrawn in a timely manner during actual use.

[0004] However, the above method still has the following drawbacks: the movable base improves the flexibility of the fire monitor, enabling the fire monitor to be quickly moved to the predetermined position or withdrawn. However, the movable base and push-pull rod take up a lot of operating space, making it inconvenient for firefighters to manually adjust the fire monitor. The adjustment process is relatively labor-intensive and time-consuming. Utility Model Content

The nozzle is rotatably connected to the gun body 6. An angle adjustment component 14 is provided at the bottom of the gun body 6 to adjust the elevation angle of the nozzle. The rigid connection between the gun body 6 and the gun base 5 is avoided by the rotary joint 17. The direction adjustment component 8 can drive the gun body 6 to rotate horizontally, which can automatically adjust the water spray direction of the nozzle. The rigid installation of the nozzle on the gun body 6 is avoided by the rotary joint 23. The angle adjustment component 14 can make the nozzle move in a circle along the rotary joint 23, which can automatically adjust the water spray angle of the nozzle without manual adjustment, saving manpower and time and improving fire extinguishing efficiency.

[0025] In this embodiment, preferably, the direction adjustment component 8 includes a mounting base 801. The bottom end of the mounting base 801 is connected to the inside of the protective shell 10. A motor 802 is fixedly mounted on the top end of the mounting base 801.

The bevel gear 804 is fixedly connected to the bottom of the gun body 6. The motor 802 can be fixedly mounted on the mounting base 801. The motor 802 drives the bevel gear 803, which in turn drives the bevel gear 804 to rotate, thereby quickly adjusting the horizontal direction of the gun body 6.

[0026] In this embodiment, preferably, the angle adjustment assembly 14 includes a support rod 1401, which is fixedly connected to the gun body 6. An electric actuator 1403 is hinged to the top of the support rod 1401, and a support arm 1405 is hinged to the telescopic rod of the electric actuator 1403. One end of the support arm 1405 is fixedly connected to the nozzle. A hinge seat 1402 is fixedly provided on one side of the top of the support rod 1401, and the bottom end of the electric actuator 1403 is hinged to the hinge seat 1402. A second hinge seat 1404 is fixedly provided at the other end of the support arm 1405. The telescopic rod of 3 is hinged to the second hinge seat 1404. A reinforcing plate 1406 is fixedly provided on one side of the top of the support rod 1401 to reinforce it. A reinforcing rib 1407 is fixedly provided on one side of the support arm 1405 to reinforce it. The rigid connection between the electric actuator 1403 and the support rod 1401 and the support arm 1405 is avoided by the first hinge seat 1402 and the second hinge seat 1404. By controlling the extension and retraction of the telescopic rod of the electric actuator 1403, the nozzle can be driven to make a circular motion along the second rotary joint 13, so that the elevation angle of the nozzle can be quickly adjusted.

[0027] In this embodiment, preferably, the bottom of the gun body 6 is rotatably connected to the top of the protective shell 10. An inspection port is provided on one side of the protective shell 10, and a cover plate 11 is fixedly installed on one side of the inspection port by screws. A storage battery 12 is fixedly installed inside the protective shell 10. The bottom of the gun body 6 can be reinforced by the protective shell 10. The storage battery 12 inside the protective shell 10 can be used as a mobile power source. By opening the cover plate 11, the inside of the protective shell 10 can be inspected through the inspection port.

[0028] In this embodiment, preferably, a handrail 15 is fixedly provided on one side of the top of the support platform 1, and reinforcing rods 16 are fixedly provided in the middle and top of the handrail 15. A flange is fixedly provided at the bottom of the gun base 5, and the bottom of the flange is fixedly connected to the top of the support platform 1 by bolts. An input pipe 9 is fixedly connected to the water inlet end of the gun base 5. The handrail 15 can be reinforced by the reinforcing rods 16. The direction of movement of the support platform 1 can be controlled by pushing the support platform 1 with the handrail 15. The gun base 5 can be fixed on the support platform 1 by the flange. Water can be supplied to the inside of the gun base 5 by the input pipe 9.

[0029] In use, first connect the input pipe 9 to the fire water pipe. Water can reach the cannon body 6 through the cannon base 5 and then be sprayed out from the nozzle for fire extinguishing. When it is necessary to adjust the spray direction of the nozzle, the motor 802 of the direction adjustment component 8 drives the bevel gear 803, which can drive the bevel gear ring 804 to rotate, thus quickly adjusting the horizontal direction of the cannon body 6. The setting of the rotary joint 7 can prevent the torque of the cannon body 6 from being transmitted to the cannon base 5. When it is necessary to adjust the elevation angle of the nozzle, control the extension rod of the electric push rod 1403 to extend and retract. The extension rod of the electric push rod 1403 can drive the nozzle to make a circular motion along the rotary joint 13 through the support arm 1405, thus quickly adjusting the elevation angle of the nozzle. The setting of the rotary joint 13 can prevent the torque of the nozzle from being transmitted to the cannon body 6. The adjustment process does not require manual adjustment, which can save manpower and time and improve fire extinguishing efficiency.

[0030] When the cannon body 6 needs to be moved, push the handle 15, and the ground wheel 4 can move the base plate 2. In special scenarios such as narrow streets in urban and rural areas, trade markets, construction sites or the interior of large venues, the cannon body 6 can be quickly moved to the designated location, and it is not easy to create a fire extinguishing blind spot. During the movement, the damping shock absorber 3 can provide buffering and vibration reduction between the base plate 2 and the support platform 1, and can maintain the stability of the cannon body 6 during movement and operation. After the movement is completed, stepping on the wheel brake of the ground wheel 4 can lock the ground wheel 4, and can prevent the base plate 2 from shifting during the fire extinguishing process.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
