DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A warning guardrail for construction engineering, comprising a guardrail body 1, a warning mechanism 7 is arranged on the top of the guardrail body 1, the number of the warning mechanisms 7 is three, a cleaning dust reduction mechanism 6 is arranged on the front side of the guardrail body 1, a water tank 11 is fixedly connected to the bottom of the guardrail body 1, a pump body 4 is arranged on the top of the water tank 11, and a light-sensitive sensor 8 is arranged on the top of the warning mechanism 7;

[0029] The warning mechanism 7 includes a rotating drum 701, a plurality of warning light strips 702, a plurality of corrugated plates 703, a plurality of warning reflective lenses 704 and a waterproof reduction motor 705. The bottom of the rotating drum 701 is fixedly connected to the top of the output shaft of the waterproof reduction motor 705, the side of the corrugated plate 703 close to the rotating drum 701 is fixedly connected to the rotating drum 701, the warning reflective lenses 704 are fixedly connected to the surface of the corrugated plate 703, and the waterproof reduction motor 705 is fixedly connected to the inside of the guardrail body 1.

[0030] Specifically, Figure 3 As shown, the top of the rotating drum 701 is fixedly connected to the control module 9 , and the bottom of the photosensor 8 is fixedly connected to the top of the control module 9 .

[0031] In this embodiment: when the light sensor 8 senses that the light is strong during the day, the signal is transmitted to the control module 9 to control the warning light bar 702 to turn off. By controlling the rotation of the waterproof reduction motor 705, the warning reflective lens 704 can reflect natural light to rotate, thereby improving the warning effect. When the light is dim at night, the light sensor 8 transmits a signal to the control module 9, and the control module 9 lights up the warning light bar 702. At this time, the warning reflective lens 704 will reflect the light emitted by the warning light bar 702 and rotate to warn, thereby achieving a warning effect when the light is dim at night.

[0032] Specifically, Figure 1 and Figure 4 As shown, the cleaning and dust reduction mechanism 6 includes three fixed pipes 601, four nozzles 602 and a three-way pipe 603. The bottom of the fixed pipe 601 is fixedly connected to the top of the guardrail body 1, the right side of the nozzle 602 is fixedly connected to the left side of the fixed pipe 601, and the rear side of the three-way pipe 603 is fixedly connected to the front side of the fixed pipe 601.

[0033] Specifically, Figure 4 As shown, the bottom of the three-way pipe 603 is fixedly connected with a connecting pipe 10 , the bottom of the connecting pipe 10 is fixedly connected with the output end of the pump body 4 , and the bottom of the input end of the pump body 4 passes through the water tank 11 and extends to the inside of the water tank 11 .

[0034] Specifically, Figure 5As shown, the top of the water tank 11 is fixedly connected with a water injection pipe 5 , and a cover body 13 is provided on the top of the water injection pipe 5 , and the surface of the cover body 13 is connected with the inner thread of the water injection pipe 5 .

[0035] Specifically, Figure 5 As shown, an air inlet 12 is provided at the top of the water tank 11 .

[0036] In this embodiment: by rotating the cover body 13, the cover body 13 is separated from the water injection pipe 5, and the water injection pipe 5 can be opened, and then the external water source is added to the water tank 11 through the water injection pipe 5. When the warning reflective lens 704 is attached with dust and affects the reflective effect, the pump body 4 is started, and the pump body 4 sucks the water in the water tank 11 through its input end, and then pressurizes the water and delivers it to the connecting pipe 10 through the output end. The water enters the three-way pipe 603 through the connecting pipe 10, and then is diverted to the three fixed pipes 601. Finally, it is sprayed from the nozzle 602 on the left side of the fixed pipe 601 to clean the rotating warning reflective lens 704 in all directions, and at the same time, the dust can be reduced in the environment. The air inlet 12 is used to take in air to maintain the pressure balance inside the water tank 11 when the pump body 4 pumps water.

[0037] Specifically, Figure 2 As shown, a through slot 2 is provided inside the guardrail body 1 , and the number of the through slots 2 is several and evenly distributed inside the guardrail body 1 .

[0038] Specifically, Figure 1 and Figure 2 As shown, legs 3 are fixedly connected to both sides of the bottom of the guardrail body 1 , and handles 14 are fixedly connected to the surface of the guardrail body 1 . There are two handles 14 symmetrically distributed on the surface of the guardrail body 1 .

[0039] In this embodiment: the guardrail body 1 is moved to the construction site where warning is required by holding the handle 14. At this time, the support legs 3 can stably support the guardrail body 1, and the through grooves 2 allow natural wind to pass through the guardrail body 1, reducing resistance and preventing the guardrail body 1 from tipping over.

[0040] Working principle: Move the guardrail body 1 to the construction site where warning is required by holding the handle 14. At this time, the legs 3 can stably support the guardrail body 1. The through groove 2 allows natural wind to pass through the guardrail body 1, reducing resistance and preventing the guardrail body 1 from tipping over. Then rotate the cover body 13. The cover body 13 is connected to the inside of the water injection pipe 5 through a thread. When the cover body 13 is rotated, the cover body 13 can be separated from the water injection pipe 5, and the water injection pipe 5 can be opened. Then, the external water source is added to the inside of the water tank 11 through the water injection pipe 5, and then the cover body 13 is reset. When the light sensor 8 detects that the ambient light is sufficient during the day, the warning light bar 702 will not be lit by the control module 9. By controlling the waterproof reduction motor 705 to rotate, The waterproof reduction motor 705 can rotate to drive the rotating drum 701, the corrugated plate 703 and the warning reflective lens 704 to rotate through the output shaft. The warning reflective lens 704 on the surface of the corrugated plate 703 uses natural light such as sunlight to reflect and scatter the light to the surroundings, attracting the attention of passers-by and vehicles, and playing a warning role. The warning reflective lens 704 is made of special optical materials with high reflectivity, and can clearly reflect light at a long distance and at different angles. At the same time, the unique shape of the corrugated plate 703 increases the diversity of the reflective area and the reflection angle, further improving the warning effect. Even when the direct sunlight angle changes greatly, it can ensure that there is enough light reflected into the surrounding environment, so that people can easily perceive the guardrail body 1 The existence of the light sensor 8 reminds people to pay attention to the danger at the construction site. When the light sensor 8 detects that the light is dim at night, the light sensor 8 transmits a signal to the control module 9, and the control module 9 starts the warning light bar 702 to light up. The warning light bar 702 emits bright light. The light passes through the gap between the corrugated plate 703 or directly shines on the warning reflective lens 704. The waterproof reduction motor 705 drives the rotating drum 701 to rotate slowly, and the corrugated plate 703 and the warning reflective lens 704 on the rotating drum 701 rotate accordingly. During the rotation process, the warning reflective lens 704 constantly changes its position, so that the reflected light beam forms a rotating effect, which is easier to attract people's attention. The warning light bar 702 adopts high-brightness, low-energy LED lamp beads, and the color of the light it emits is eye-catching. The utility model has strong penetrating power in a dark environment, so that the guardrail body 1 can continuously and effectively warn passing personnel and vehicles at night or in a low-light environment, and ensure the safety of the construction site. When the warning reflective lens 704 is attached with dust and affects the reflective effect, the pump body 4 is started, and the pump body 4 sucks the water in the water tank 11 through its input end, and then pressurizes the water and delivers it to the connecting pipe 10 through the output end. The water enters the three-way pipe 603 through the connecting pipe 10, and then flows into the three fixed pipes 601, and finally sprays out from the nozzle 602 on the left side of the fixed pipe 601 to clean the rotating warning reflective lens 704 in all directions, and at the same time, the dust can be reduced in the environment, avoiding the existing problem that the warning signs in the warning guardrails for construction engineering are fixed and not flexible.The visual angle and range of the warning sign are limited to a certain extent. In a complex construction site environment, such as when there are multiple buildings, large construction equipment or different terrains, fixed warning signs may not ensure that people approaching the construction area from all directions can clearly see the warning information, and it is not convenient to achieve the warning effect at night. It should be noted that the photosensitive sensor 8 and the control module 9 are both existing mature technologies that have been published, and their appearances are diverse, so they will not be described in detail here.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
