[0002] During the construction process of a construction project, safety is always a crucial consideration. With the continuous development and increasing scale of construction projects, the complexity of the construction site is also increasing day by day. In construction project management, safety warning devices play an indispensable role.

[0003] According to the search, the Chinese patent document, publication number: CN217556752U, discloses a safety warning device for construction project management. When it is necessary to fix the warning board, the lower surface of the warning board can be placed on the upper surface of the support column to fit the fixing plate, and then the rotary handle is rotated to drive the bidirectional lead screw to rotate. The rotation of the bidirectional lead screw drives two groups of moving blocks to move. The movement of the two groups of moving blocks drives the position of the connecting rod to change. The connecting rod drives the moving plate to move in the limiting groove, and the moving plate drives the pressing plate to adjust to a suitable position to fix and install the warning board, which is convenient for fixing operations on warning boards of different widths.

[0004] However, the above warning device can only play a role in fixing the warning board during actual use, and has a single function in use and cannot cope with the environment of the construction site. Content of the Utility Model

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a safety warning device for construction project management.

[0006] To achieve the above object, the present utility model provides the following technical solution: A safety warning device for construction project management, including a base. The interior of the base is hollow, and two columns are bolted to the upper surface of the base. The top of the two columns is clamped with a top plate. A gear reduction box is installed on the top surface of one of the top plates, and a volute is installed on the top of the other top plate. A warning board is installed between the two columns. An impeller is rotatably connected inside the volute. The center of the end face of the impeller is fixedly connected with a rotating shaft. One end of the rotating shaft is fixedly connected with a transmission rod. The output shaft of the gear reduction box is fixedly connected with a rotating plate. A shaft rod is fixedly connected to a position near one end of the outer surface of the rotating plate. A connecting plate is in sliding contact with the outer surface of the shaft rod. One end of the connecting plate is fixedly connected with a first rotating rod. One end of the first rotating rod is fixedly connected with a spray pipe. The outer surface of the first rotating rod is rotatably connected with a first side plate. One end of the spray pipe is fixedly connected with a second rotating rod. The outer surface of the second rotating rod is rotatably connected with a second side plate. A booster pump is installed on the top surface of the base. The output end of the booster pump is connected with a water delivery pipe, and the water inlet end of the booster pump is connected with a water suction pipe. A pipe joint is fixedly connected to the outer surface of the volute, and the top end of the pipe joint is connected with a hose.

[0007] In the above, both ends of the warning board are fixedly connected with two lugs, and the lugs are bolted to the outer surface of the column. A reflective strip is pasted on the front of the warning board.

[0008] In the above, a water inlet valve is installed on one side of the base, and the base is in a trapezoidal structure. The end of the water suction pipe away from the booster pump is fixedly connected to the other side of the base.

[0009] In the above, the end of the water delivery pipe away from the booster pump is connected to the outer surface of the volute. A diversion pipe is fixedly connected inside the volute, and the diversion pipe is communicated with the water delivery pipe.

[0010] In the above, the end of the hose away from the pipe joint is fixedly connected with the second rotating rod. The second rotating rod is a hollow rod and is communicated with the spray pipe. A plurality of atomizing nozzles are equidistantly installed on the outer surface of the spray pipe.

[0011] In the above, the end of the transmission rod away from the rotating shaft is connected to the input shaft of the gear reduction box. A straight groove is formed through the outer surface of the connecting plate, and the shaft rod is in sliding contact with the straight groove.

[0012] In the above, two snap plates are fixedly connected to the bottom of the top plate. The interior of the column is hollow, and card holes matching the snap plates are opened at both ends of the column.

[0013] Compared with the prior art, the safety warning device for construction project management has the following beneficial effects:

[0014] First, the utility model stores water inside the base. On the one hand, it increases the overall stability of the device. On the other hand, it provides a water source for spray dust suppression. After starting the booster pump, water enters the volute through the water delivery pipe and then sprays out from the atomizing nozzle, realizing spray dust suppression at the construction site. The addition of this function enables the warning device not only to play a warning role but also to effectively reduce dust pollution during construction, improve the environmental quality of the construction site, and provide better protection for construction workers and the surrounding environment.

[0015] Second, when water flows into the guide pipe inside the volute of the utility model, it impacts the fan blades of the impeller, causing the impeller to rotate, and then drives a series of transmission components to operate. Finally, through the speed regulation of the gear reduction box and the action of the relevant connecting rod mechanism, the spray pipe can swing back and forth, and the atomizing nozzle also swings accordingly. This design greatly increases the spray range and thus improves the dust suppression range. Compared with the traditional dust suppression method using fixed nozzles, this device can more comprehensively and effectively cover the dust area of the construction site, improve the dust suppression efficiency, and embody the perfect combination of energy conservation, environmental protection and high-efficiency dust suppression.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-5 shown, the present invention provides a technical solution: a safety warning device for construction project management, including a base 1. The interior of the base 1 is hollow, and two columns 2 are bolted to the upper surface of the base 1. The top of the two columns 2 is clamped with a top plate 3. A gear reduction box 4 is installed on the top surface of one of the top plates 3, and a volute 5 is installed on the top of the other top plate 3. A warning board 22 is installed between the two columns 2. An impeller 6 is rotatably connected inside the volute 5. The center of the end face of the impeller 6 is fixedly connected with a rotating shaft 7. One end of the rotating shaft 7 is fixedly connected with a transmission rod 8. The output shaft of the gear reduction box 4 is fixedly connected with a rotating plate 9. A shaft rod 10 is fixedly connected to a position near one end of the outer surface of the rotating plate 9. A connecting plate 11 is in sliding contact with the outer surface of the shaft rod 10. One end of the connecting plate 11 is fixedly connected with a first rotating rod 12. One end of the first rotating rod 12 is fixedly connected with a nozzle 13. The outer surface of the first rotating rod 12 is rotatably connected with a first side plate 14. One end of the nozzle 13 is fixedly connected with a second rotating rod 15. The outer surface of the second rotating rod 15 is rotatably connected with a second side plate 16. A booster pump 17 is installed on the top surface of the base 1. The output end of the booster pump 17 is connected with a water delivery pipe 18, and the water inlet end of the booster pump 17 is connected with a water suction pipe 19. A pipe joint 20 is fixedly connected to the outer surface of the volute 5, and the top of the pipe joint 20 is connected with a hose 21.

[0025] As Figures 1-2 shown, two connecting ears 221 are fixedly connected to both ends of the warning board 22. The connecting ears 221 are bolted to the outer surface of the column 2, and a reflective strip 23 is pasted on the front of the warning board 22.

[0026] By arranging lugs 221 on both sides of the warning board 22 and cooperating with bolts, it can be connected to the column 2. Since the column 2 and the base 1 are also connected by bolts, such a modular design can be disassembled, facilitating transportation. And a plurality of reflective strips 23 are pasted on the warning board 22 to reflect light, which can also play a certain warning role at night. The warning board 22 can isolate the construction site from the external environment, thus making the construction site operate in a standardized manner.

[0027] As Figures 2-4 shown, a water inlet valve 24 is installed on one side of the base 1, and the base 1 is in a trapezoidal structure. One end of the suction pipe 19 far from the booster pump 17 is fixedly connected to the other side of the base 1.

[0028] One end of the water delivery pipe 18 far from the booster pump 17 is connected to the outer surface of the volute 5. A guide pipe 25 is fixedly connected inside the volute 5, and the guide pipe 25 is communicated with the water delivery pipe 18.

[0029] One end of the hose 21 far from the pipe joint 20 is fixedly connected to the second rotating rod 15. The second rotating rod 15 is a hollow rod, and the second rotating rod 15 is communicated with the spray pipe 13. A plurality of atomizing nozzles 26 are equidistantly installed on the outer surface of the spray pipe 13.

[0030] By hollowing out the inside of the base 1 to form a water storage cavity and connecting the water inlet valve 24 to a water source, which can come from a municipal water pipe. In this way, when the water inlet valve 24 is opened, water can be injected into the inside of the base 1. On the one hand, it can increase the weight of the base 1, thus improving the stability of the entire warning device. On the other hand, it provides water for subsequent spray dust reduction. When the booster pump 17 is started and cooperates with the suction pipe 19, the water inside the base 1 can be pumped into the water delivery pipe 18, then into the volute 5, and then discharged from the pipe joint 20 and flow into the hose 21. Since the second rotating rod 15 is a hollow rod, the water can continue to be transported to the spray pipe 13 and finally sprayed out from a plurality of atomizing nozzles 26. In this way, it can spray in the construction site to achieve the purpose of dust reduction, making the warning device not only have a warning function but also be able to achieve the purpose of dust reduction, increasing its functionality.

[0031] As Figures 3-4 shown, one end of the transmission rod 8 far from the rotating shaft 7 is connected to the input shaft of the gear reduction box 4. A straight groove is formed through the outer surface of the connecting plate 11, and the shaft rod 10 is in sliding contact inside the straight groove.

[0032] By arranging a diversion pipe 25 for connecting a water delivery pipe 18, when water flows into the water delivery pipe 18, it will immediately flow into the diversion pipe 25. The outlet direction of the diversion pipe 25 is aligned with the fan blades of the impeller 6. In this way, under the impact of the water flow, the impeller 6 can be driven to rotate. The impeller 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the transmission rod 8 to rotate, the transmission rod 8 drives the input shaft of the gear reduction box 4 to rotate. The rotational speed can be reduced through the gear reduction box 4. Then, the output shaft of the gear reduction box 4 drives the rotating plate 9 to rotate slowly. The rotating plate 9 drives the shaft rod 10 to rotate. Since the outer surface of the shaft rod 10 is in sliding contact with the straight groove of the connecting plate 11, when the shaft rod 10 rotates, it can drive the connecting plate 11 to make a reciprocating swinging motion. The connecting plate 11 immediately drives the first rotating rod 12, and the first rotating rod 12 drives the spray pipe 13 to swing back and forth. In this way, multiple atomizing nozzles 26 can swing back and forth, so as to increase the spraying range and further improve the dust reduction range.

[0033] As Figure 5 shown, two snap plates 27 are fixedly connected to the bottom of the top plate 3. The inside of the column 2 is hollow, and card holes 28 matching the snap plates 27 are opened at both ends of the column 2.

[0034] By integrally connecting two snap plates 27 to the bottom of the top plate 3, only need to insert the two snap plates 27 into the top of the column 2, and then press the top plate 3. In this way, the snap plates 27 can be engaged with the card holes 28, so that the top plate 3 can be quickly installed on the top of the column 2.

[0035] Working principle: Assemble the entire warning device at the construction site. The warning board 22 is used to remind people not to approach the construction site. Connect the water inlet valve 24 to the municipal water source. When the water inlet valve 24 is opened, water can be injected into the base 1, so as to improve the stability of the warning device. Subsequently, after starting the booster pump 17 and cooperating with the suction pipe 19, the water in the base 1 can be pumped into the water delivery pipe 18, and then into the diversion pipe 25. The water flow immediately impacts the fan blades of the impeller 6, causing the impeller 6 to rotate. The impeller 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the transmission rod 8 to rotate, the transmission rod 8 drives the input shaft of the gear reduction box 4 to rotate. The rotational speed can be reduced through the gear reduction box 4. Then, the output shaft of the gear reduction box 4 drives the rotating plate 9 to rotate slowly. The rotating plate 9 drives the shaft rod 10 to rotate. After the shaft rod 10 rotates, it can drive the connecting plate 11 to make a reciprocating swinging motion. The connecting plate 11 immediately drives the first rotating rod 12, and the first rotating rod 12 drives the spray pipe 13 to swing back and forth. In this way, multiple atomizing nozzles 26 can swing back and forth. Since the water will immediately be discharged from the pipe joint 20 and flow into the hose 21 after entering the volute 5, then the water is delivered to the spray pipe 13 through the second rotating rod 15, and finally sprayed out from several atomizing nozzles 26, so as to spray at the construction site and achieve the purpose of dust reduction.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
