Description

Technical Field

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

[0002] Firefighting is about eliminating hidden dangers and preventing disasters. In its narrow sense, it initially meant extinguishing fires. It mainly includes personnel rescue at fire scenes, the rescue of important facilities, equipment, and cultural relics, the protection and rescue of important property, and the extinguishing of fires. The goal is to reduce the degree of damage caused by fires and minimize casualties and property losses.

[0003] A search revealed a utility model patent in China with patent publication number CN219558582U, which discloses a fire sprinkler system. The system generally includes a base plate with two sets of rollers fixedly connected to its bottom surface. A housing is fixedly connected to the upper surface of the base plate, and a first booster pump is fixedly connected to the inner wall of the housing. During use, the device moves via the rollers and a push plate. The first and second booster pumps, combined with connecting hoses and a three-way telescopic hose, allow water to be sprayed onto the fire. The push plate can be moved via the engagement of a threaded rod and a threaded hole. The device moves up and down, allowing the push plate to control the rotation of the nozzle via the top rod, thus adjusting the angle of the second nozzle and enabling it to spray water onto the fire. This solves the problem of difficulty in adjusting the nozzle angle, which previously hindered the spraying of water onto the fire. However, the above device still has some shortcomings. For example, it is not convenient to adjust the height of the first nozzle and the two second nozzles, and the adjustment angle of the second nozzle is limited, only allowing for vertical angle adjustment. Its applicability and practicality are somewhat insufficient. Therefore, we propose a fire sprinkler system. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a fire sprinkler system with the following advantages:

[0018] This fire sprinkler system uses an electric cylinder to raise and lower the mounting plate and rotating seat, facilitating height adjustment of multiple sprinkler heads. It also allows for coordination between motor one, gears, gear rings, and the rotating seat. Left and right angle adjustment of two sprinkler heads is possible, facilitating coordination between motor two, the rotating shaft, and the spray pipe. Vertical angle adjustment of the sprinkler heads makes water spraying more flexible, allowing for easier coordination between the booster pump, hose two, and hose one to supply water to the sprinkler heads. This enhances practicality and applicability, and makes controlling the entire system for firefighting operations more convenient. Attached Figure Description

A mounting base 13 is fixedly connected to the mounting plate 8. A [missing information - likely a device or component] is fixedly connected to the mounting base 13 and the two rotating seats 9. An adjusting frame 14 has two rotating shafts rotatably connected to it. A water spray pipe 15 is fixedly connected between the two rotating shafts. A nozzle 16 is installed on the water spray pipe 15. A second motor 17 is installed on the adjusting frame 14. The output end of the second motor 17 passes through the adjusting frame 14 and is fixedly connected to one of the rotating shafts. A first hose 18 is connected to the nozzle 16. A diversion pipe 19 is connected to the three first hoses 18. A second hose 20 is connected to the diversion pipe 19. The second hose 20 is connected to the fixed pipe 6. A receiving trough 5 is used to receive the second hose 20. A pump, first hose 18, etc. are added for water supply. The nozzle 16 is used for spraying water. An electric cylinder 7 can adjust the height of the nozzle 16. A first motor 11, gear 12, gear ring 10, etc. are used to adjust the spray position of the nozzle 16, while the second motor 17 is used to adjust the spray angle of the nozzle 16.

[0031] The mounting plate 8 is provided with a protective cover 21, which has two openings. The rotating seat 9 is located in the openings to protect the gear 12, gear ring 10, etc.

[0032] Both the mounting plate 8 and the adjusting bracket 14 are equipped with protective covers 22 to protect motor one 11 and motor two 17.

[0037] In summary, the working principle and process of this fire sprinkler system are as follows: First, place the fire sprinkler system at the desired location and connect motor 11 and motor 217 according to the corresponding instruction manual to establish the forward and reverse circuits. Then, when using the system, fill the water tank 2 with water and start the electric cylinder 7. The electric cylinder 7 can drive the mounting plate 8 and multiple nozzles 16 to adjust their height. After adjusting to the required height, start motor 11 and motor 217. Motor 11 drives gear 12 to rotate, and gear 12 drives one of the gear rings 10 to rotate, which in turn drives another gear ring 10 to rotate. This allows for the left and right angle adjustment of two of the nozzles 16. Motor 217 drives the rotating shaft, water pipe 15, and nozzles 16 to rotate, facilitating the up and down angle adjustment of the nozzles 16. Then, start the booster pump 3, which draws water from the water tank 2 and delivers the water to the three nozzles 16 through hose 20 and diversion pipe 19, thus enabling the nozzles 16 to spray water for fire extinguishing.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
