[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a warning sign for construction projects, including a sign body 1 and a support base 2. The sign body 1 is installed on the top of the support base 2. A protective cleaning mechanism 3 for cleaning and protecting the warning sign is installed on the top of the support base 2. An L-shaped toothed plate 4 is fixedly connected to the bottom of the protective cleaning mechanism 3. The L-shaped toothed plate 4 is driven by a limiting mechanism 5 through meshing. The limiting mechanism 5 is installed on the top of the support base 2. A circular hole is opened on the surface of the limiting mechanism 5 at a position corresponding to the surface of the support base 2. The bottom of the limiting mechanism 5 passes through the circular hole and is fixedly connected to a limiting plate 6. A driving component 7 is installed on one end of the support base 2. The inner wall of the driving component 7 is fixedly connected to one end of the protective cleaning mechanism 3.

[0027] By setting up the protective cleaning mechanism 3, the warning sign is protected when it is not in use. The drive component 7 is activated to provide driving force so that the protective cleaning mechanism 3 moves on the surface of the sign body 1, thereby cleaning the warning sign. At the same time, when the protective cleaning mechanism 3 moves, it drives the L-shaped toothed plate 4 at the bottom to move. The L-shaped toothed plate 4 is then driven by the limiting mechanism 5 to support the limiting plate 6 on the ground, improving the stability of the warning sign when it is in use. This prevents the warning sign from being exposed to the outside world, protects the surface of the warning sign, and provides convenience for the operator's cleaning work.

[0028] The protective cleaning mechanism 3 includes a support plate 31, and there are two sets of support plates 31. Both sets of support plates 31 are fixedly connected to the upper surface of the support base 2. The top of the two sets of support plates 31 is provided with a positive and negative threaded rod 32. Both ends of the positive and negative threaded rod 32 are rotatably connected to the inner side wall of the support plate 31 through a rotating shaft. One end of the positive and negative threaded rod 32 passes through one set of support plates 31 and is fixedly connected to the inner wall of the drive assembly 7. The outer surface of the positive and negative threaded rod 32 is connected to the cleaning assembly 33 through threads. When the drive assembly 7 is activated, it provides driving force to drive the positive and negative threaded rod 32 to rotate, so that the positive and negative threaded rod 32 drives the cleaning assembly 33 to clean the warning sign through the threaded connection.

[0029] The cleaning component 33 includes two sets of cleaning plates 331. Each set of cleaning plates 331 has a threaded hole at its top, the inner cavity of which is threaded to the outer surface of a positive and negative threaded rod 32. Both sets of cleaning plates 331 have through holes at their bottom ends, through which a sliding limit rod 332 is inserted and slidably connected. Both ends of the limit rod 332 are fixedly connected to the inner sidewalls of the two sets of support plates 31. Pleated protective curtains 333 are fixedly connected to the sidewalls of both sets of cleaning plates 331, with the other end of each pleated protective curtain fixed to the inner sidewall of the support plate 31. The connection includes a set of cleaning plates 331 whose bottom ends are fixedly connected to an L-shaped toothed plate 4. The positive and negative threaded rods 32 are connected to the threaded holes, so that when the positive and negative threaded rods 32 rotate, they can drive the cleaning plates 331 to move. The setting of the limit rods 332 prevents the positive and negative threaded rods 32 from causing the cleaning plates 331 to flip, so that the cleaning plates 331 can only move within the inner cavity of the support plate 31. The cleaning plates 331 rub against the surface of the card body 1 to clean the dust on the surface of the card body 1. At the same time, the cleaning plates 331 can drive the pleated protective curtain 333 to shield and protect the surface of the card body 1.

[0030] The limiting mechanism 5 includes a support frame 51, which is fixedly connected to the upper surface of the support base 2. A rotating rod 52 is rotatably connected to the inner cavity of the support frame 51 via a rotating shaft. Both ends of the rotating rod 52 pass through the support frame 51 and are fixedly connected to cams 53. A support assembly 54 is provided at the bottom end of the cams 53. The bottom end of the support assembly 54 passes through a circular hole and is fixedly connected to the top end of the limiting plate 6. A turbine 55 is provided on the outer surface of the rotating rod 52, and a rotating assembly 56 is meshed with the surface of the turbine 55. The cleaning plate 331 drives the L-shaped toothed plate 4 to move, causing the L-shaped toothed plate 4 to rotate through the meshing connection, which in turn drives the rotating assembly 56 to rotate. The rotating assembly 56, through the meshing connection, drives the turbine 55 to rotate, causing the turbine 55 to press against the support assembly 54 via the rotating rod 52, thus causing the support assembly 54 to move the limiting plate 6 downwards.

[0031] The support assembly 54 includes an overlapping plate 541. A support column 542 is fixedly connected to the bottom end of the overlapping plate 541. A horizontal plate 543 is fixedly connected to the bottom end of the support column 542 through a circular hole. The bottom end of the horizontal plate 543 is fixedly connected to the top end of the limiting plate 6. A through hole is opened at the end of the horizontal plate 543 away from the support column 542. A ground nail rod 544 is sleeved in the inner cavity of the through hole of the horizontal plate 543. A first spring 545 is fixedly connected to the bottom end of the ground nail rod 544. The other end of the first spring 545 is fixedly connected to the top end of the horizontal plate 543. There are two sets of overlapping plates 541, and both sets of overlapping plates 541 are located directly below the cam 53. The cam 53 presses the overlapping plates 541, causing the overlapping plates 541 to push the horizontal plate 543 to move through the support column 542. This causes the horizontal plate 543 to drive the limiting plate 6 to contact the ground. Then, the ground nail rod 544 is pressed into the ground, improving the stability of the warning sign.

[0032] A second spring 8 is sleeved on the outer surface of the support column 542. The second spring 8 is located between the overlapping plate 541 and the support seat 2. With the setting of the second spring 8, when the cam 53 releases the pressure on the overlapping plate 541, the second spring 8 rebounds to assist the overlapping plate 541 in resetting. The overlapping plate 541 drives the horizontal plate 543 to move through the support column 542, and the horizontal plate 543 drives the limiting plate 6 to move upward to cancel contact with the ground.

[0033] The rotating assembly 56 includes an L-shaped plate 561, the bottom end of which is fixedly connected to the top end of the support base 2. A through hole is provided on the surface of the L-shaped plate 561. A worm gear 562 is rotatably connected to the inner cavity of the through hole of the L-shaped plate 561 through a rotating shaft. The surface of the top end of the worm gear 562 meshes with the surface of the turbine 55. The bottom end of the worm gear 562 passes through the L-shaped plate 561 and is fixedly connected to a gear 563. The surface of the gear 563 meshes with the surface of the L-shaped toothed plate 4. The movement of the L-shaped toothed plate 4 drives the gear 563 to rotate through the meshing connection, causing the gear 563 to drive the worm gear 562 at the top end to rotate. The worm gear 562 drives the turbine 55 to rotate through the meshing connection.

[0034] The drive assembly 7 includes a stepper motor 71, which is fixedly mounted on the top of the support base 2. The output shaft of the stepper motor 71 is fixedly connected to a first sprocket 72. The first sprocket 72 is driven by a chain to a second sprocket 73. The inner wall of the second sprocket 73 is fixedly connected to one end of the positive and negative threaded rod 32. When the stepper motor 71 is started, it drives the first sprocket 72 to rotate. The first sprocket 72 drives the second sprocket 73 to rotate through the chain, so that the second sprocket 73 drives the positive and negative threaded rod 32 to rotate.

[0035] The support base 2 is equipped with casters 9 around its bottom. An L-shaped fixing plate 10 is fixedly connected to the top of the support base. There are two sets of L-shaped fixing plates 10, both of which are located directly behind the sign body 1. The casters 9 facilitate the movement of the warning sign, while the L-shaped fixing plates 10 provide support and improve the stability of the warning sign during operation.

[0036] In practical use: When using this device, first push it to a suitable position, start the stepper motor 71 to drive the first sprocket 72 to rotate. The first sprocket 72 drives the second sprocket 73 to rotate through chain transmission, causing the second sprocket 73 to drive the positive and negative threaded rod 32 to rotate. The rotation of the positive and negative threaded rod 32 can drive the two sets of cleaning plates 331 to move away from each other, thereby achieving the folding and storage process of the two sets of pleated protective curtains 333. At this time, the two sets of pleated protective curtains 333 no longer block the main body of the warning sign. Under the action of the main body of the warning sign, it can play a warning role during the construction process. In the process of driving the two sets of cleaning plates 331 to move away from each other, the front end of the main body of the warning sign can be cleaned and wiped, thereby preventing the warning sign from being exposed to the outside world, protecting the surface of the warning sign, and providing convenience for the cleaning work of the operators.

[0037] Simultaneously, the movement of the two sets of vertical plates drives the movement of the L-shaped toothed plate 4. The L-shaped toothed plate 4, through meshing with the gear 563, drives the worm gear 562 to rotate. The worm gear 562, through meshing, drives the turbine 55 to rotate. The turbine 55, through the rotating rod 52, drives the cams 53 at both ends to press against the overlapping plate 541. The overlapping plate 541, through the support column 542, pushes the horizontal plate 543 to move. The horizontal plate 543 drives the limiting plate 6 to contact the ground. Then, the ground nail rod 544 is pressed and inserted into the ground. At this time, the movement of the device can be restricted. Then, both sets of ground nail rods 544 are inserted into the soil to further increase the stability of the device during use.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
