Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire safety technology, specifically a fire sprinkler device with a large spraying range. Background Technology
[0002] Fire sprinkler systems are a crucial type of fire extinguishing equipment. Traditional fixed fire sprinkler systems mainly rely on deflectors to control the spray range. The principle of the deflector is to disperse and guide the water sprayed from the nozzles. However, since the deflector is fixed in size and position, the spray range is relatively small. In practical applications, such as large warehouses, high-ceilinged factories, or buildings with complex structures, once a fire breaks out, the fire often spreads rapidly. Because the spray range of traditional sprinkler systems is limited, it is difficult to cover a large area. This means that some areas may not be sprayed in time, thus affecting the fire extinguishing effect. Utility Model Content
[0003] To overcome the aforementioned shortcomings, this utility model provides a fire sprinkler device with a large spray range, solving the problem that traditional fixed fire sprinkler devices have a relatively small spray range due to the fixed position and size of the deflector plate. In large warehouses, high-ceilinged factories, or buildings with complex structures, it is difficult to cover a large area, which may result in some areas not being sprayed in time, thus affecting the fire extinguishing effect.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fire sprinkler device with a large spray range, comprising a support bracket, a support slider below the support bracket, a support base fixedly connected below the support slider, a rotating shaft rotatably connected to the center position inside the support base, a driven gear fixedly connected to the outer wall of the rotating shaft, the bottom end of the rotating shaft penetrating the bottom of the support base and a turntable fixedly connected to its end, an output motor fixedly installed on one side of the support base, the output end of the output motor penetrating one side of the support base and a driving gear fixedly connected to its end, the driving gear meshing with the driven gear, a spray element fixedly connected below the turntable, a plurality of spray holes opened on the outer wall of the spray element, a connecting pipe rotatably connected to the bottom of the spray element, and a connecting member fixedly connected to the other end of the connecting pipe.
[0005] As a further embodiment of this utility model: two slide rails are fixedly installed on both sides of the support bracket, and two sets of pulleys are symmetrically fixedly installed on the inner wall of the support slider, with the two sets of pulleys rotating above the two slide rails respectively.
[0006] As a further embodiment of this utility model: a support screw is rotatably connected between the inner walls of the support bracket, and a control motor is fixedly installed on one side of the support bracket, with the output end of the control motor connected to one end of the support screw.
[0007] As a further embodiment of this utility model: an adjusting slider is fixedly installed at the top of the supporting slider at its center position, the adjusting slider is located inside the supporting bracket, and the supporting screw passes through the adjusting slider and is threadedly connected to the adjusting slider.
[0008] As a further embodiment of this utility model: two sets of connecting protrusions are symmetrically fixedly installed on the top of the support bracket about its center, and a connecting bolt is provided on one side of the connecting protrusion, the connecting bolt passing through the connecting protrusion.
[0009] As a further embodiment of this utility model: the spray hole is designed with an inclination, and the spray hole faces downwards from the spraying component.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This fire sprinkler system with a large spray range is equipped with a rotating shaft, driven gear, turntable, and sprinkler components. When using the system, water is supplied to the sprinkler components through a connector. The output motor drives the drive gear to rotate, which in turn drives the rotating shaft through the driven gear. The rotating shaft drives the turntable to rotate, and the turntable drives the sprinkler components to spray the water supplied to the sprinkler components through centrifugal force. Furthermore, by adjusting the speed of the output motor, flexible control can be achieved over the spray range and intensity. This eliminates the limitations of traditional fixed splash plates that make it difficult to flexibly adjust the spray range, thus improving the overall spray range.
[0012] 2. This fire sprinkler system with a large spray range utilizes a support screw, an adjusting slider, and a supporting slider. When in use, a control motor drives the support screw to rotate. During this rotation, the adjusting slider, threadedly connected to the support screw, moves the supporting slider horizontally under the action of its threads. The supporting slider moves above the slide rail via pulleys, reducing friction during movement. This horizontal movement of the spray nozzles further expands the spray range, allowing the sprinklers to cover more areas. For example, in large industrial plants, the placement of equipment and goods may obstruct the fire-fighting effect of fixed sprinkler systems. However, by moving the sprinklers, obstacles can be bypassed, and water can be sprayed directly to the areas requiring fire suppression. Attached Figure Description

Detailed Implementation
[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-4As shown, this utility model provides a technical solution: a fire sprinkler device with a large spray range, including a support bracket 1, a support slider 2 below the support bracket 1, two slide rails 13 fixedly installed on both sides of the support bracket 1, two sets of pulleys 14 symmetrically fixedly installed on the inner wall of the support slider 2, the two sets of pulleys 14 rotating above the two slide rails 13 respectively. Because of the pulleys 14, the support slider 2 rotates above the slide rails 13 during movement, which can reduce the friction of the support slider 2 during movement, reduce energy loss, and enable quick and easy movement of the spray element 9 when the position needs to be frequently adjusted, improving the response speed of the device, helping to expand or adjust the spray range in a timely manner, and enhancing the fire extinguishing effect. A support base 3 is fixedly connected below the support slider 2, and a rotating shaft 4 is rotatably connected to the center of the support base 3. A driven gear 5 is fixedly connected to the outer wall of the rotating shaft 4. The bottom end of the rotating shaft 4 passes through the bottom of the support base 3 and a turntable 6 is fixedly connected to the end. An output motor 7 is fixedly installed on one side of the support base 3. The output end of 7 passes through one side of the support base 3 and is fixedly connected to the end of the drive gear 8. The drive gear 8 meshes with the driven gear 5. A spray element 9 is fixedly connected to the lower part of the turntable 6. The outer wall of the spray element 9 has several spray holes 10. The spray holes 10 are designed to be inclined, facing downwards from the spray element 9. The inclined angle allows the sprayed water to have a greater initial velocity in the horizontal direction, thus covering a greater distance. In the event of a fire in a narrow space, it can effectively spray water to a more distant fire source. On the other hand, multiple spray holes 10 can ensure that there is enough water to be sprayed evenly to the surrounding area at different rotation angles, avoiding the situation of local spraying failure, and greatly improving the comprehensiveness of fire extinguishing. The bottom of the spray component 9 is rotatably connected to the connecting pipe 11. This rotatable connection method allows the connecting pipe 11 and the spray component 9 to maintain good water flow during the rotation of the spray component 9, ensuring that the water supply will not be affected by the rotation of the spray component 9. The other end of the connecting pipe 11 is fixedly connected to the connector 12.
[0020] A support screw 15 is rotatably connected between the inner walls of the support bracket 1. A control motor 16 is fixedly installed on one side of the support bracket 1, and the output end of the control motor 16 is connected to one end of the support screw 15. An adjusting slider 17 is fixedly installed at the center of the top of the support slider 2. The adjusting slider 17 is located inside the support bracket 1. The support screw 15 passes through the adjusting slider 17 and is threadedly connected to the adjusting slider 17. Through the cooperation between the support screw 15 and the adjusting slider 17, during the rotation of the support screw 15, the adjusting slider 17 drives the support slider 2 to move horizontally under the action of the thread. The support slider 2 drives the spray element 9 to move, causing the spray element to move. The sprinkler unit 9 can be moved above or closer to the fire source to further expand its spray range. The top of the support bracket 1 is symmetrically fixed with two sets of connecting protrusions 18 about its center. One side of the connecting protrusion 18 is provided with a connecting bolt 19, which passes through the connecting protrusion 18. Because of the connecting bolt 19, by tightening the connecting bolt 19, the support bracket 1 can be firmly installed on the ceiling of the building or other suitable fixed positions. In the event of a fire, the entire sprinkler device will not loosen or fall off due to vibration, impact or other factors, ensuring the reliability and safety of the device and ensuring that it can play a normal fire extinguishing role at critical moments.
[0021] The working principle of this utility model is as follows: When using the device, the connecting part 12 is connected to a water source with stable pressure. When a fire source is detected, the control motor 16 drives the support screw 15 to rotate. The rotation of the support screw 15, through cooperation with the adjusting slider 17, drives the support slider 2 to move horizontally. The support slider 2 drives the spray element 9 to move above or relatively close to the fire source. Water is delivered into the spray element 9 through the connecting pipe 11. During the water delivery process, the output end of the output motor 7 drives the drive gear 8 to rotate. The drive gear 8 drives the driven gear 5 to rotate, which in turn drives the turntable 6 to rotate through the rotating shaft 4. The turntable 6 drives the spray element 9 to rotate. The water in the spray element 9 is sprayed out through the spray hole 10 by centrifugal force. The range of centrifugal spraying is controlled by controlling the speed of the output motor 7.
