Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a rooftop heatstroke prevention spraying machine. Background Technology

[0002] The fire prevention and heatstroke prevention sprinkler system on the roof of a building is a system specifically designed for construction sites to prevent fires and alleviate high temperatures in summer.

[0003] Existing fire prevention and heatstroke prevention sprinkler systems for building rooftops are installed on the roof and spray water through nozzles to cool and reduce dust around the building. By designing the nozzles to have a rotating spraying function to increase the spraying range, the spraying range is still limited due to the limited size of the nozzles. For large building rooftops, they are still unable to effectively cover them.

[0004] In view of this, this application proposes a new technical solution. Utility Model Content

[0005] The purpose of this utility model is to provide a rooftop construction heatstroke prevention spraying machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A rooftop heatstroke prevention sprinkler machine includes a water inlet pipe and a sprinkler head. The bottom of the water inlet pipe is positioned and supported on the rooftop by support legs. One end of the water inlet pipe is connected to a water source, and the other end is connected to the sprinkler head through a secondary transmission mechanism. The water is then sprayed outward through the sprinkler head. The secondary transmission mechanism includes a primary swing transmission component and a secondary swing transmission component. The secondary swing transmission component is located at the end of the primary swing transmission component. While swinging itself, it also rotates with the swing transmission component to control the sprinkler head to perform large-area swing spraying. The primary swing transmission component includes a main swing cylinder located at the top of the water inlet pipe. The bottom of the main swing cylinder is rotatably connected to a fixed rotating base via an electrically driven swing component. The side wall of the fixed rotating base is supported and positioned by multiple evenly distributed support legs. A transmission channel is opened in the middle of the fixed rotating base and the main swing cylinder. The bottom end of the transmission channel is connected to the water inlet pipe, and the top end is connected to a U-shaped primary swing transmission pipe. At the same time, a main frame parallel to the primary swing transmission pipe is fixedly installed on the main swing cylinder below the primary swing transmission pipe. The end of the primary swing transmission pipe away from the main swing cylinder is connected to the secondary swing transmission component via a connecting cylinder. One side of the connecting cylinder is fixed to the end of the main frame. That is, under the transmission of the primary swing transmission pipe, the heatstroke prevention spray liquid in the water inlet pipe is transferred to the secondary swing transmission component. At the same time, the rotational position and angle of the primary swing transmission pipe and the secondary swing transmission component are adjusted as a whole by using the rotational connection of the main swing cylinder placed on the fixed rotating base. The secondary swing transmission component includes an auxiliary positioning cylinder that is rotatably connected to the bottom of the connecting cylinder. An electrically driven swing component is installed at the bottom of the auxiliary positioning cylinder, which controls the rotation between the auxiliary positioning cylinder and the connecting cylinder. The bottom end of the auxiliary positioning cylinder is connected downward to a secondary swing transmission pipe with a Z-shaped structure. The end of the secondary swing transmission pipe is connected to the spray head. By adjusting the angle of the secondary swing transmission pipe through the rotatable connection between the auxiliary positioning cylinder and the connecting cylinder, the secondary rotation adjustment of the spray head is realized, thereby further expanding the spray range.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by using a two-stage independently controlled swing mechanism, the composite motion trajectory of the spray head is realized, which greatly expands the spray coverage area; With its ability to adjust in both horizontal and vertical directions, it can adapt to the layout requirements of different building rooftops. The electric-driven oscillating structure ensures smooth operation, high transmission accuracy, and reduces interference from water flow fluctuations. The balance block design effectively counteracts the inertial torque of rotating components, improving equipment stability. Modular design facilitates installation and maintenance, reducing the difficulty of working at heights. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-3 A rooftop heatstroke prevention sprinkler machine includes a water inlet pipe 12 and a spray head 13. The bottom of the water inlet pipe 12 is positioned and supported on the rooftop by a support leg 11. One end of the water inlet pipe is connected to a water source, and the other end is connected to the spray head 13 through a secondary transmission mechanism. Spraying is then carried outward through the spray head 13. That is, the water inlet pipe 12 is fixed to the rooftop by the support leg 11, and its outlet end is connected to a primary swing transmission mechanism and a secondary swing transmission mechanism in sequence. The end of the secondary swing transmission mechanism is connected to the spray head 13. The secondary transmission mechanism includes a primary swing transmission component and a secondary swing transmission component. The secondary swing transmission component is located at the end of the primary swing transmission component. While swinging itself, it also rotates with the swing transmission component to control the spray head 13 to perform large-area swing spraying. The primary swing transmission component includes a main swing cylinder 16 located at the top of the water inlet pipe 12. The bottom of the main swing cylinder 16 is rotatably connected to a fixed rotating base 25 via an electrically driven swing mechanism. Specifically, the bottom of the main swing cylinder 16 is rotatably connected to the fixed rotating base 25 via an electrically driven swing mechanism. The sidewalls of the fixed rotating base 25 are supported and positioned by multiple evenly distributed support legs 11. A transmission channel 24 is formed in the middle of the fixed rotating base 25 and the main swing cylinder 16. The bottom end of the transmission channel 24 is connected to the water inlet pipe 12, and the top end is connected to a U-shaped primary swing transmission pipe 20. Simultaneously, in the primary... A main frame 10 parallel to the primary swing transmission pipe 20 is fixedly installed on the main swing cylinder 16 below the swing transmission pipe 20. The end of the primary swing transmission pipe 20 away from the main swing cylinder 16 is connected to the secondary swing transmission component through the connecting cylinder 28. One side of the connecting cylinder 28 is fixed to the end of the main frame 10. That is, under the transmission of the primary swing transmission pipe 20, the heatstroke prevention spray liquid in the water inlet pipe 12 is transferred to the secondary swing transmission component. At the same time, the rotational connection of the main swing cylinder 16 placed on the fixed rotating base 25 is used to adjust the rotational position angle of the primary swing transmission pipe 20 and the secondary swing transmission component as a whole. The secondary swing transmission component includes an auxiliary positioning cylinder 17 that is rotatably connected to the bottom of the connecting cylinder 28. An electrically driven swing component is provided at the bottom of the auxiliary positioning cylinder 17, which controls the rotation between the auxiliary positioning cylinder 17 and the connecting cylinder 28. The bottom end of the auxiliary positioning cylinder 17 is connected downward to a secondary swing transmission pipe 19 with a Z-shaped structure. The end of the secondary swing transmission pipe 19 is connected to the spray head 13. Through the rotatable connection between the auxiliary positioning cylinder 17 and the connecting cylinder 28, the angle of the secondary swing transmission pipe 19 can be adjusted to achieve secondary rotational adjustment of the spray head 13, thereby further expanding the spraying range. The support leg 11 is designed with an L-shaped structure, and its bottom is fixedly installed on the roof of the building. In this embodiment of the utility model, the water source is generally set as a heatstroke prevention spray tank under the building or groundwater, which is connected to the inlet end of the water inlet pipe 12 through water pipes distributed on the exterior wall of the building. Spray head 13 uses an existing rotary nozzle to spray the heatstroke prevention spray liquid outwards fully and quickly; The primary swing transmission tube 20 is fixed to the main frame 10 by the tube positioning block 15. The secondary swing transmission tube 19 is equipped with a fixing rod 18. The end of the fixing rod 18 is fixed to one side of the adjacent fixed rotating base 25, thereby stabilizing and limiting the secondary swing transmission tube 19 and the primary swing transmission tube 20.

[0019] In one embodiment of this utility model, multiple pumps can be installed at the inlet end of the secondary swing transmission pipe 19, the primary swing transmission pipe 20, or the water inlet pipe 12 according to the spraying requirements, to ensure that the heatstroke prevention spray liquid can have sufficient power for transmission.

[0020] As a preferred embodiment of this utility model, taking the electrically driven swing component between the bottom of the main swing cylinder 16 and the fixed rotating base 25 as an example, the electrically driven swing component includes a T-shaped rotating block 26 connected to the bottom of the main swing cylinder 16. A T-shaped rotating groove 27 is formed inside the top of the fixed rotating base 25 corresponding to the T-shaped rotating block 26. The T-shaped rotating block 26 is rotatably connected within the T-shaped rotating groove 27, that is, the T-shaped rotating block 26 is rotatably connected within the T-shaped rotating groove 27; simultaneously, in the main swing cylinder... A gear ring 23 is installed on the lower outer wall of the 16. A drive tooth 22 is engaged on one side of the upper part of the gear ring 23. A first-stage servo motor 21 is connected to one side of the drive tooth 22. The bottom of the first-stage servo motor 21 is fixed on the fixed rotating base 25. At this time, by starting the first-stage servo motor 21, the drive tooth 22 is driven to rotate, thereby driving the drive tooth 22 to control the gear ring 23 to rotate. This controls the T-shaped rotating block 26 to rotate inside the T-shaped rotating groove 27. Then, the rotation of the main swing cylinder 16, the main frame 10, the first-stage swing transmission pipe 20 and other subsequent structures are adjusted. Among them, the electric drive swing component at the bottom of the auxiliary positioning cylinder 17 is a two-stage servo motor 29. The top of the two-stage servo motor 29 is fixed to the bottom of the main frame 10 by a connecting rod. The T-shaped rotating block 26 and the T-shaped rotating groove 27 are set between the top of the auxiliary positioning cylinder 17 and the bottom of the connecting cylinder 28. The gear ring 23 is set on the lower outer wall of the auxiliary positioning cylinder 17. The drive tooth 22 meshes with the gear ring 23, and one side of it is connected to the output shaft of the two-stage servo motor 29. That is, by starting the two-stage servo motor 29 to rotate the drive tooth 22, the gear ring 23 is driven to control the auxiliary positioning cylinder 17 to rotate. At this time, the T-shaped rotating groove 27 at the top of the auxiliary positioning cylinder 17 and the T-shaped rotating block 26 at the bottom of the connecting cylinder 28 rotate, and then drive the two-stage swing transmission pipe 19 at the bottom to rotate and spray.

[0021] In a preferred embodiment of the present invention, a balance block 14 is provided at the end of the main frame 10 away from the auxiliary positioning cylinder 17. The balance block 14 is used to maintain the balance at both ends of the main swing cylinder 16, that is, to ensure the overall stability when controlling the main frame 10 to rotate and driving the spray head 13 and other structures at the end of the main frame 10 to rotate in a secondary manner.

[0022] The working principle of this utility model is as follows: the water source enters the transmission channel 24 through the water inlet pipe 12, and is transported to the main swing cylinder 16 through the fixed rotating base 25; The primary servo motor 21 drives the drive gear 22 to rotate the gear ring 23, causing the main swing cylinder 16 to rotate in the T-shaped rotating groove 27 through the T-shaped rotating block 26, which in turn drives the primary swing transmission tube 20 to rotate horizontally. Water flows through the primary swing transmission pipe 20 into the connecting cylinder 28, and then into the auxiliary positioning cylinder 17; The secondary servo motor 29 drives the gear ring 23 at the bottom of the auxiliary positioning cylinder 17, causing the secondary swing transmission tube 19 to swing in the vertical direction. The spray liquid is finally sprayed out from the spray head 13 in a rotating and diffused manner; The balance block 14 maintains the stability of the main frame 10 during movement, and the tube positioning block 15 and the fixing rod 18 fix the primary swing transmission tube 20 and the secondary swing transmission tube 19, respectively.

However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0024] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
