As a key device for information dissemination in engineering projects, information broadcasters can ensure that information is delivered to every relevant person in a timely and accurate manner during the project's progress.

[0003] Most existing information broadcasting devices are fixed installations, and their broadcasting direction is difficult to adjust flexibly. They can only broadcast information to fixed areas. This means that when it is necessary to convey information to people in different areas at the construction site, it may not be possible to achieve effective information coverage, which affects the dissemination of information. Utility Model Content

[0004] The purpose of this invention is to provide an information broadcasting device for engineering projects. It features a rotating mechanism where a motor output shaft drives a rotating shaft. Through the meshing of gears and a ring rack, a rotating seat rotates within a support ring. The ring-shaped protrusion on the outer wall of the rotating seat slides within a ring-shaped groove on the inner wall of the support ring, ensuring rotational stability. The rotation of the rotating seat drives the mounting plate and the broadcaster to rotate, allowing for flexible adjustment of the broadcasting direction. This enables the broadcaster to broadcast information to different areas, meeting the diverse information dissemination needs of engineering project sites. It also solves the problem that most existing information broadcasting devices are fixed installations, making it difficult to flexibly adjust the broadcasting direction and limiting their broadcasting to fixed areas.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an information broadcasting device for engineering projects, comprising a mobile vehicle body, on which a rotating mechanism and a disassembly mechanism are provided.

[0007] The rotating mechanism includes a support ring fixedly connected to the bottom of the vehicle body. A rotating seat is rotatably connected to the inner wall of the support ring. The top of the rotating seat passes through the vehicle body and is rotatably connected to the vehicle body. An annular protrusion is fixedly connected to the outer wall of the rotating seat. An annular groove is formed on the inner wall of the support ring. The outer wall of the annular protrusion extends into the interior of the annular groove and is slidably connected to the annular groove. A mounting plate is slidably connected to the top of the rotating seat. A broadcaster is fixedly connected to the top of the mounting plate. The disassembly mechanism includes a connecting block fixedly connected to the bottom of the mounting plate.

[0008] Furthermore, a motor is fixedly connected to the bottom of the vehicle body, and the output shaft of the motor is fixedly connected to a rotating shaft through a coupling. The top end of the rotating shaft passes through the vehicle body and is rotatably connected to the vehicle body.

[0009] Furthermore, a gear is fixedly connected to the outer wall of the rotating shaft, and an annular rack is fixedly connected to the outer wall of the rotating seat, with the gear meshing with the annular rack.

[0010] Furthermore, the top of the rotating seat is provided with a connecting groove, and the bottom of the connecting block extends into the interior of the connecting groove and is slidably connected to the connecting groove.

[0011] Furthermore, the bottom of the mounting plate is fixedly connected to two guide posts, and the top of the rotating seat is provided with two guide grooves. The bottom ends of the two guide posts extend into the interior of the corresponding guide grooves and are slidably connected to the corresponding guide grooves.

[0012] Furthermore, positioning grooves are provided on both the front and rear sides of the connecting block, and two sliding grooves are provided on the outer wall of the rotating seat.

[0013] Furthermore, each of the two slide grooves has a slide rod slidably connected to its inner wall, a connecting piece fixedly connected to the outer wall of each slide rod, and a spring wound around the outer wall of each slide rod.

[0028] Please see Figure 1-5 As shown, this utility model is an information broadcasting device for engineering projects, including a mobile vehicle body 1. The mobile vehicle body 1 is equipped with a rotating mechanism 2 and a disassembly mechanism 3. The rotating mechanism 2 includes a support ring 21 fixedly connected to the bottom of the mobile vehicle body 1. A rotating seat 22 is rotatably connected to the inner wall of the support ring 21. The top of the rotating seat 22 passes through the mobile vehicle body 1 and is rotatably connected to it. An annular protrusion 23 is fixedly connected to the outer wall of the rotating seat 22. An annular groove 24 is formed on the inner wall of the support ring 21. The outer wall of the annular protrusion 23 extends into the interior of the annular groove 24 and is slidably connected to it. A mounting plate 25 is slidably connected to the top of the rotating seat 22. A broadcaster 26 is fixedly connected to the top of the mounting plate 25. The disassembly mechanism 3 includes a connecting block 31 fixedly connected to the bottom of the mounting plate 25. A motor 27 is fixedly connected to the bottom of the mobile vehicle body 1. The output shaft of motor 27 is fixedly connected to a rotating shaft 28 via a coupling. The top end of the rotating shaft 28 passes through the vehicle body 1 and is rotatably connected to the vehicle body 1. A gear 29 is fixedly connected to the outer wall of the rotating shaft 28, and a ring rack 210 is fixedly connected to the outer wall of the rotating seat 22. The gear 29 meshes with the ring rack 210. By setting a rotating mechanism 2, the output shaft of motor 27 drives the rotating shaft 28 to rotate. Through the meshing transmission of gear 29 and ring rack 210, the rotating seat 22 rotates within the support ring 21. The ring protrusion 23 on the outer wall of the rotating seat 22 slides within the ring groove 24 on the inner wall of the support ring 21, ensuring the stability of the rotation. The rotation of the rotating seat 22 drives the mounting plate 25 and the broadcaster 26 to rotate, which can flexibly adjust the broadcasting direction, allowing the broadcaster 26 to broadcast information to different areas, meeting the different information dissemination needs of the engineering project site.

[0029] The top of the rotating base 22 is provided with a connecting groove 32. The bottom of the connecting block 31 extends into the interior of the connecting groove 32 and is slidably connected to the connecting groove 32. The bottom of the mounting plate 25 is fixedly connected to two guide posts 33. The top of the rotating base 22 is provided with two guide grooves 34. The guide grooves 34 are located at the top of the rotating base 22. The bottom ends of the two guide posts 33 extend into the interior of the corresponding guide grooves 34 and are slidably connected to the corresponding guide grooves 34. The front and rear sides of the connecting block 31 are provided with positioning grooves 35. The outer wall of the rotating base 22 is provided with two sliding grooves 36. The inner walls of the two sliding grooves 36 are slidably connected to sliding rods 37. The outer walls of the two sliding rods 37 are fixedly connected to connecting pieces 38. The outer walls of the two sliding rods 37 are wound with springs 39. The springs 39 are used to provide elastic force for the positioning block 310 to return to its original position. One end of each spring 39 is fixedly connected to the corresponding connecting piece 38. The other end of each spring 39 is fixedly connected to the inner wall of the corresponding sliding groove 36. The ends of the two sliding rods 37 that are close to each other are fixed. The device is connected to a positioning block 310. The side of the two positioning blocks 310 away from the corresponding slide bar 37 extends into the corresponding positioning groove 35 and slides in connection with the corresponding positioning groove 35. The ends of the two slide bars 37 away from each other are fixedly connected to a pull ring 311. By setting a disassembly mechanism 3, when it is necessary to disassemble the broadcaster 26, the pull ring 311 is pulled, which drives the slide bar 37 to make the positioning block 310 exit from the positioning groove 35 of the connecting block 31. The connecting block 31 can be pulled out from the connecting groove 32, and the guide post 33 can be pulled out from the guide groove 34 to complete the disassembly. During installation, the connecting block 31 is inserted into the connecting groove 32, and the guide post 33 is inserted into the guide groove 34. By utilizing the structure of the connecting block 31 and the positioning block 310, the connecting block 31 is locked by the cooperation of the positioning block 310 and the positioning groove 35. The positioning block 310 is inserted into the positioning groove 35 under the action of the spring 39 to complete the fixation. This facilitates the maintenance and replacement of the broadcaster 26, improves the maintainability of the device, and ensures that the device can continuously and stably carry out information broadcasting.

[0030] A specific application of this embodiment is as follows: When using this device, the vehicle body 1 can move on the construction site, driving the entire information broadcasting device to the location where information needs to be broadcast. When the direction of the broadcaster 26 needs to be adjusted, the motor 27 is started. The output shaft of the motor 27 drives the rotating shaft 28 to rotate. Since the outer wall of the rotating shaft 28 is fixedly connected to the gear 29, and the outer wall of the rotating seat 22 is fixedly connected to the ring rack 210, and the gear 29 meshes with the ring rack 210, the rotating shaft 28 will rotate through the gear 29. The meshing transmission between the 9 and the ring rack 210 drives the rotating seat 22 to rotate within the support ring 21. The rotating seat 22 is rotatably connected to the inner wall of the support ring 21. The annular protrusion 23 on the outer wall of the rotating seat 22 slides within the annular groove 24 on the inner wall of the support ring 21, ensuring the stability of the rotation of the rotating seat 22. When the rotating seat 22 rotates, it drives the mounting plate 25 and the announcer 26 on the top of the mounting plate 25 to rotate through the disassembly mechanism 3, thereby adjusting the direction of the announcer 26 so as to broadcast information to different areas.

[0031] When the announcer 26 needs to be disassembled for maintenance or replacement, pull the pull ring 311. The pull ring 311 drives the slide rod 37 to slide in the slide groove 36. The slide rod 37 drives the connecting piece 38 to compress the spring 39. At the same time, the slide rod 37 drives the positioning block 310 to exit from the positioning groove 35 of the connecting block 31. At this time, the connecting block 31 at the bottom of the mounting plate 25 can be pulled out from the connecting groove 32 at the top of the rotating seat 22. At the same time, the guide post 33 is pulled out from the guide groove 34, thereby removing the mounting plate 25 and the announcer 26. During installation, the connecting block 31 is inserted into the connecting groove 32, and the guide post 33 is inserted into the guide groove 34. The installation position of the connecting block 31 is guided and positioned by the guide post 33 and the guide groove 34. The bottom of the side of the block 310 that is in contact is arc-shaped, and the top of the positioning block 310 is sloping. Therefore, when the connecting block 31 moves downward and contacts the positioning block 310, it will push the positioning block 310 into the slide groove 36, thereby driving the slide rod 37 and the connecting piece 38 to move. This causes the spring 39 to contract, so that the positioning block 310 gradually retracts into the slide groove 36. When the connecting block 31 is fully inserted into the connecting groove 32, the positioning block 310 and the positioning groove 35 are on the same horizontal line. At this time, the spring 39 returns to its original position under its own elasticity, thereby driving the slide rod 37 to move through the connecting piece 38. Then, the slide rod 37 drives the positioning block 310 to be inserted into the positioning groove 35, completing the installation and fixing of the mounting plate 25 and the announcer 26.
