Description

Technical Field

[0001] This utility model relates to the field of announcement devices, and in particular to an announcement device for water conservancy engineering construction. Background Technology

[0002] In the construction of water conservancy projects, notice boards (also known as announcement display boards) play a crucial role. These devices display important announcements such as construction progress, safety instructions, and warnings, ensuring timely and transparent communication of information at the construction site. This, in turn, improves construction efficiency, ensures construction safety, and facilitates personnel coordination. By clearly and explicitly displaying construction progress, safety instructions, and warnings, notice boards achieve comprehensive transparency of information at the construction site. Construction workers, management personnel, and visitors can quickly access the latest project updates and safety requirements, reducing information delays and misunderstandings, and improving work efficiency and response speed.

[0003] Currently, most notice boards for water conservancy project construction on the market use the method of directly pasting paper notices. These paper notices often require a large amount of double-sided tape or glue for pasting. While this method is simple and easy, when the notice content needs to be updated, construction workers have to painstakingly tear off the old notice. This process is not only time-consuming and labor-intensive, but also easily damages the surface of the notice board, affecting the pasting effect of subsequent notices. Furthermore, residual glue or double-sided tape is difficult to completely remove, causing inconvenience for pasting new notices. Therefore, a new notice board for water conservancy project construction is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a notification device for water conservancy project construction, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

A toothed plate is fixedly connected to the outlet end, and the toothed plate meshes with a gear. A back plate is fixedly installed on the inner wall of the bulletin box by bolts. The back plate corresponds vertically to the winding frame. A paper tape is fixedly connected to the inner wall of the winding frame. The paper tape is slidably connected to the back plate. A frame is fixedly connected to the bottom surface of the bulletin box. A clamping platform is fixedly connected to the inner wall of the frame. A clamping plate is slidably connected to the inner wall of the frame. The clamping plate corresponds to the clamping platform. A threaded post is threadedly connected to the back of the frame. One end of the threaded post is rotatably connected to the clamping plate through a bearing. The paper tape is located between the clamping plate and the clamping platform.

[0007] Preferably, of any of the above solutions, a rain cover is fixedly connected to the top surface of the bulletin box, and the motor and gear are located below the rain cover.

[0008] Preferably, in any of the above embodiments, the front of the bulletin box is connected to a door via a hinge, and a transparent glass is embedded in the inner wall of the door, the transparent glass corresponding to the back panel.

[0009] Preferably, of any of the above embodiments, an L-shaped bracket is fixedly connected to the inner wall of the bulletin box, a paper guide roller is rotatably connected to the bottom of the L-shaped bracket, the paper strip is slidably connected to the paper guide roller, and the paper guide roller is vertically corresponding to the winding frame.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. When pasting paper notices, open the box door, apply glue to the back of the notice, and stick it onto the paper tape. Then close the box door. The notice can be viewed through the transparent glass. When replacing the notice, twist the threaded column. The threaded drive will move the clamping plate away from the clamping table, releasing the paper tape from the lock. Then turn on the motor to rotate the winding frame, unwinding the paper tape and pulling the bottom of the tape through the slot downwards until the paper tape with the notice attached has moved out of the notice box. Then, lock the paper tape back in place using the clamping plate. Finally, peel off the paper tape with the notice attached. This method makes it easy to replace the paper tape with the notice attached without having to tear off the old notice, and it will not affect the pasting effect of subsequent notices.

Through the threaded transmission, the clamping plate 13 can be moved away from the clamping table 12, which can release the lock on the paper tape 10. Then, turn on the motor 4 to drive the winding frame 3 to rotate, which can unwind the paper tape 10.

[0032] 3): Pull the bottom of the paper tape 10 to make it pass through the slot 20 and move downwards until the paper tape 10 with the notice attached has moved out of the notice box 1. Then, use the clamping plate 13 to lock the paper tape 10 again. Finally, tear off the paper tape 10 with the notice attached.

[0033] In summary, this water conservancy project construction notice device allows for easy viewing of paper notices by opening the box door 16, applying glue to the back of the notice, and attaching it to the paper tape 10. The box door 16 is then closed, and the notice can be viewed through the transparent glass 17. To replace the paper notice, the threaded post 14 is twisted, which, through threaded transmission, moves the clamping plate 13 away from the clamping table 12, releasing the paper tape 10. The motor 4 is then turned on, causing the winding frame 3 to rotate, unwinding the paper tape 10 and pulling its bottom through the slot 20. The paper tape 10 with the notice attached moves downwards until it exits the notice box 1. Then, the paper tape 10 is locked again by the clamping plate 13. Finally, the paper tape 10 with the notice attached can be torn off. This makes it easy to replace the paper tape 10 with the notice attached without having to tear off the old notice. It will not affect the pasting effect of the subsequent notices. After the winding frame 3 has rotated, the motor 4 can be turned off. Then, the cylinder 7 is turned on to drive the toothed plate 8 close to the gear 5, which can lock the gear 5, thereby achieving the purpose of locking the winding frame 3. This can prevent the winding frame 3 from rotating and ensure that the paper tape 10 remains taut.
