Description

Technical Field

[0001] The utility model relates to a safety warning device, in particular to a safety warning device applied in the technical field of water conservancy engineering. Background Art

[0002] A water conservancy project is a construction project that manages and controls natural water sources. During the construction of a water conservancy project, in order to remind people of the dangers of the construction site, warning signs are generally placed in front of the construction site to warn people not to approach and improve safety performance during the construction process.

[0003] The specification of Chinese patent CN217231540U discloses a safety warning device for water conservancy project construction, including a base, an adjusting mechanism is arranged inside the base, and the adjusting mechanism extends to the outside of the base; the adjusting mechanism includes a limit groove, the limit groove is arranged on the top of the base, a motor is fixedly connected to one side of the base, and a bidirectional screw is fixedly connected to the motor output shaft. The beneficial effect of a safety warning device for water conservancy project construction is that when the height of the entire device needs to be adjusted, the bidirectional screw drives the two threaded blocks to move toward each other when rotating, and the two threaded blocks cooperate with the two inclined plates through two hinges, so that the two support blocks drive the two support sleeves to move upward, and at the same time, the support rod limits the support sleeve, so that the support sleeve drives the connecting frame to move upward more stably, thereby realizing the convenience of adjusting the height of the device at any time, not easy to cause blind spots, ensuring the warning effect, and having good practicality.

[0004] The specification of Chinese patent CN212533815U discloses a safety warning device for water conservancy project construction, including a rod body, a telescopic rod movably connected to the lower surface of the rod body, a connecting block fixedly connected to one side of the rod body, a No. 1 plate movably connected between the two connecting blocks via a rotating shaft, through holes are provided on the upper and lower sides of the No. 1 plate, a No. 2 plate is movably connected to the surface of the through hole, a No. 3 plate is clamped on one side of the No. 2 plate, and a connecting block is movably connected to one side of the No. 3 plate. The safety warning device for water conservancy project construction can be rolled up to form a roughly cylindrical body during transportation through the rollable arrangement between the rod body, the No. 1 plate, the No. 2 plate and the No. 3 plate, which greatly reduces the space occupied by the safety warning device and solves the problem that the existing warning device is inconvenient to transport and occupies too much space. The detachable arrangement at one end of the main rod and the reinforcement rod is prepared for rolling up the safety warning.

[0005] When using traditional warning signs, it was found that due to the severe dust at the construction site, the warning signs are easily contaminated with dust, resulting in people not being able to see the meaning expressed on them, thereby significantly reducing the warning function and effect. In the later stage, they need to be manually cleaned again and again, and their performance is poor. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that due to the serious dust at the construction site, the warning signs are easily stained with dust, resulting in people not being able to see the meaning expressed thereon, thereby significantly reducing the warning function and warning effect.

[0007] In order to solve the above problems, the utility model provides a safety warning device, including a warning sign symmetrically mounted on a roller shaft, blocks fixedly connected at both ends of the roller shaft, detachable sleeves connected to the roller shafts on both sides of the warning sign, a connecting groove fixedly connected between the two sleeves, an electric slide rail fixedly connected in the connecting groove, a connecting plate slidably connected to the electric slide rail, a slider fixedly connected to the bottom end of the connecting plate, and the slider is slidably connected to the electric slide rail, symmetrical perforations are drilled on both sides of the connecting plate, a bottom plate is rotatably connected in the perforations through a rotating shaft, a cleaning brush is fixedly connected to one end of the bottom plate close to the warning sign, and the cleaning brush conflicts with the warning sign.

[0008] In the above safety warning device, the effect of automatically and regularly cleaning the dust on the surface of the warning sign is effectively achieved.

[0009] As a further improvement of the present application, two warning signs are alternately sleeved on the roller shaft, and the two warning signs can overlap.

[0010] As a further improvement of the present application, two warning signs are fixedly connected with a clamping plate at one end close to each other, and a hinge is rotatably connected to the clamping plate.

[0011] As a further improvement of the present application, a card frame is fixedly connected to the bottom of the side end of the warning sign, and the inner wall of the card frame is symmetrically cut with sliding grooves.

[0012] As another improvement of the present application, a handle is slidably connected in the slide groove, and a binding rope is sleeved on the handle.

[0013] As another improved supplement of the present application, a battery is fixedly installed in the card sleeve, and a charging head is drilled on the card sleeve.

[0014] As another improved supplement of the present application, a sealing cover is rotatably connected to the side of the charging head, a sealing gasket is fixedly connected to the sealing cover, and the sealing gasket is engaged with the charging head.

[0015] To sum up, this solution can be realized. When the warning sign is used for a long time at the construction site, a large amount of dust will cover it, making the writing on it blurred. When placing the warning sign, the card sleeve can be driven to drive the connecting groove to be fixed on the roller shaft, and then the bottom plate can be rotated by the shaft to adjust the angle of the cleaning brush so that it contacts the surface of the warning sign. Then, the electric slide rail is turned on to drive the connecting plate to drive the two cleaning brushes to move back and forth, so that the cleaning brush and the warning sign are rubbed and wiped clean. When the electric slide rail is used for a long time and the battery in the card sleeve is exhausted, the sealing cover can be opened and the battery can be charged by connecting the charger to the charging head, so that the electric slide rail can be used continuously, effectively achieving the effect of automatically and regularly cleaning the dust on the surface of the warning sign.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-2 and Figure 6-7 A safety warning device is shown, including a warning sign 1 symmetrically sleeved on a roller shaft 2, with blocks 3 fixedly connected at both ends of the roller shaft 2, and detachable sleeves 8 are connected to the roller shaft 2 on both sides of the warning sign 1, with a connecting groove 4 fixedly connected between the two sleeves 8, an electric slide rail fixedly connected in the connecting groove 4, a connecting plate 9 slidably connected to the electric slide rail, a slider 14 fixedly connected to the bottom end of the connecting plate 9, and the slider 14 is slidably connected to the electric slide rail, symmetrical perforations are drilled on both sides of the connecting plate 9, a bottom plate 15 is rotatably connected in the perforations through a rotating shaft, a cleaning brush 5 is fixedly connected to one end of the bottom plate 15 close to the warning sign 1, and the cleaning brush 5 conflicts with the warning sign 1.

[0028] Figure 3 It is shown that a battery is fixedly installed in the card sleeve 8, and a charging head 10 is cut on the card sleeve 8. The charging head 10 is rotatably connected to a sealing cover 11 on the side, and a sealing gasket is fixedly connected to the sealing cover 11, and the sealing gasket is engaged with the charging head 10.

[0029] This solution can be achieved. When the warning sign 1 is used for a long time at the construction site, a large amount of dust will cover it, making the writing on it blurred. When placing the warning sign 1, the sleeve 8 can be used to drive the connecting groove 4 to be fixed on the roller 2, and then the bottom plate 15 can be rotated by the shaft to adjust the angle of the cleaning brush 5 so that it contacts the surface of the warning sign 1. Then, the electric slide rail is turned on to drive the connecting plate 9 to drive the two cleaning brushes 5 to move back and forth, so that the cleaning brush 5 and the warning sign 1 are rubbed and wiped clean. When the battery in the sleeve 8 is exhausted after the electric slide rail is used for a long time, the sealing cover 11 can be opened and the battery can be charged by connecting the charging head 10 through the charger, so that the electric slide rail can be used continuously, effectively achieving the effect of automatically and regularly cleaning the dust on the surface of the warning sign 1.

[0030] The second implementation method:

[0031] Figure 1-2 and Figure 4-5 It is shown that two warning signs 1 are staggered and sleeved on the roller 2, and the two warning signs 1 can overlap, and a clamping plate is fixedly connected to one end of the two warning signs 1 close to each other, and a hinge 6 is rotatably connected to the clamping plate, and a clamping frame 12 is fixedly connected to the bottom of the side end of the warning sign 1, and a sliding groove 13 is symmetrically carved on the inner wall of the clamping frame 12, and a handle 7 is slidably connected in the sliding groove 13, and a binding rope 16 is sleeved on the handle 7.

[0032] This solution can be achieved. When the warning sign 1 is used for a long time at the construction site, a large amount of dust will cover it, making the writing on it blurred. When placing the warning sign 1, the sleeve 8 can be used to drive the connecting groove 4 to be fixed on the roller 2, and then the bottom plate 15 can be rotated by the shaft to adjust the angle of the cleaning brush 5 so that it contacts the surface of the warning sign 1. Then, the electric slide rail is turned on to drive the connecting plate 9 to drive the two cleaning brushes 5 to move back and forth, so that the cleaning brush 5 and the warning sign 1 are rubbed and wiped clean. When the battery in the sleeve 8 is exhausted after the electric slide rail is used for a long time, the sealing cover 11 can be opened and the battery can be charged by connecting the charging head 10 through the charger, so that the electric slide rail can be used continuously, effectively achieving the effect of automatically and regularly cleaning the dust on the surface of the warning sign 1.

[0033] This solution can achieve that when the warning sign 1 is needed at the construction site, the two warning signs 1 can be opened by rotating them, and the rotation simultaneously drives the hinge 6 to rotate and straighten to provide support between the two warning signs 1, and then the warning sign 1 is placed at the required location. When the warning sign 1 falls on the ground, the handle 7 is retracted into the card frame 12 by sliding. When the warning sign 1 is not in use, it can be rotated and retracted so that the two warning signs 1 are folded together. At this time, the warning sign 1 is turned upside down and the handle 7 is slid out of the card frame 12. The two handles 7 are tied together by the binding rope 16 to position the warning sign 1, and the warning sign 1 can be taken and placed by holding the handle 7, effectively achieving the effect of conveniently retracting and taking the warning sign 1.

[0034] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted by this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
