Description

Technical Field

[0001] The utility model relates to the technical field of safety warning devices, in particular to a safety warning device for building construction projects. Background Technique

[0002] Safety warning signs on construction sites are one of the indispensable safety facilities in building construction. Their main function is to remind workers and passing pedestrians of safety issues at the construction site and avoid accidental injuries. Warning signs are usually set at prominent positions on the construction site, such as at the main entrance, on the perimeter wall, etc., and can include different types of warnings, such as high-altitude operations, electrical equipment, dangerous areas, etc.

[0003] The utility model with the publication number of CN219457053U discloses a safety warning device for building construction projects. Through the positioning mechanism, multiple safety warning boards for building construction projects can be spliced, and the length of the safety warning can be adjusted according to actual needs. Through the rotation between the safety warning board for building construction projects and the support legs, the warning area can be adjusted according to actual needs, and it can be adjusted according to the actual situation to meet different usage requirements.

[0004] The construction site is usually relatively open in the initial stage and has little resistance to wind. In windy weather, since the above warning device usually has a large area, it will bear a large thrust. At the same time, since the warning sign has a light structure and low strength, it is extremely easy to deform or overturn, affecting subsequent normal use, and workers need to repair it. It is inconvenient to use in windy areas. Therefore, in view of the above problems, a safety warning device for building construction projects is now proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a safety warning device for building construction projects. The safety warning device can display warning information through the warning board. In windy weather, under the impact of air flow, the disc will rotate to open the pressure relief hole, and the air flow will pass through the pressure relief hole, thereby greatly reducing the wind load on the warning board, effectively preventing the overall deformation or overturning of the device. When the wind stops, the disc will reset to cover the pressure relief hole to avoid affecting the viewing of warning information, solving the technical problem that in the prior art, the warning device is prone to deformation or overturning due to bearing a large wind load in windy weather, thereby affecting subsequent normal use.

[0006] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0007] A safety warning device for housing construction projects, including a height-adjustable swivel bracket, on which a warning plate with a pressure relief hole is installed, the warning plate is sprayed with warning information, and a pressure relief component is rotatably arranged in the pressure relief hole, wherein a rotation groove is arranged on the warning plate, and the rotation groove is located at the upper and lower sides of the pressure relief hole, the pressure relief component includes a disc that matches the size of the pressure relief hole, and the upper and lower ends of the disc are fixedly connected with a rotation shaft, and the rotation shaft is rotatably arranged in the rotation groove.

[0008] Through the above-mentioned structural form, the warning information is displayed on the warning board to play a warning reminder role. In windy weather, the disc will rotate under the impact of the airflow to open the pressure relief hole, and the airflow will pass through the pressure relief hole, thereby greatly reducing the wind load on the warning board, and can effectively prevent the entire device from being deformed or overturned. When the strong wind stops, the disc will reset to cover the pressure relief hole to avoid affecting the viewing of the warning information.

[0009] In a possible implementation, the longitudinal section of the rotating shaft is I-shaped, and a return torsion spring is provided on the outer sleeve of the inner concave section thereof, the bottom end of the return torsion spring is fixedly connected to the rotating shaft, and the top end of the return torsion spring is fixedly connected to the wall of the rotating groove.

[0010] Through the above-mentioned structural form, when the disc rotates under the influence of airflow, it will drive the rotating shaft to rotate, so that elastic potential energy is accumulated in the reset torsion spring. When the wind stops or the wind speed drops significantly, under the action of the reset torsion spring, the disc will rotate to reset and cover the pressure relief hole, so as to display the warning information.

[0011] In a possible implementation, a first magnet mounting groove is opened on both sides of the pressure relief hole, and a static adsorption magnet is installed in the first magnet mounting groove. A second magnet mounting groove is opened on both sides of the disc, and a dynamic adsorption magnet is installed in the second magnet mounting groove.

[0012] With the above-mentioned structural form, since the reset torsion spring relies on elastic potential energy to reset, it is difficult to ensure that the disc can be completely reset every time. The reset torsion spring can usually only restore the disc to an approximate position. At this time, under the mutual adsorption effect of the static adsorption magnet and the dynamic adsorption magnet, the rotation amplitude of the disc can be further adjusted so that it can be reset as completely as possible.

[0013] In a possible implementation, after the static adsorption magnet is installed and fixed, its N pole faces upward, and after the dynamic adsorption magnet is installed and fixed, its S pole faces upward.

[0014] The above-mentioned structural form can ensure that a positive and non-deflected adsorption force can be generated between the static adsorption magnet and the dynamic adsorption magnet, thereby completely resetting the auxiliary disc.

[0015] In a possible implementation, a number of side slot holes are arranged on the front end face of the disc on the left side, and the same number of side slot holes are arranged on the rear end face of the disc on the left side.

[0016] With the above structural form, the opened side slot holes can have a stronger blocking effect on the airflow, so that one side of the disc can receive a greater wind thrust, avoiding the extreme situation where the wind loads on both sides are the same and the disc cannot rotate.

[0017] In a possible implementation, the height-adjustable rotating bracket includes side struts, an installation frame is slidably arranged between the side struts, and a warning board is installed in the installation frame.

[0018] With the above structural form, the adjustment of the installation height of the warning board can be realized.

[0019] In a possible implementation, sliding grooves are opened on the side struts, position fixing screws are fixedly arranged on both sides of the installation frame, the position fixing screws are slidably arranged in the sliding grooves, and locking handwheels are threadedly connected to the ends of the position fixing screws.

[0020] With the above structural form, when adjusting the installation height of the warning board, the position fixing screws will slide synchronously in the sliding grooves. After the height of the warning board is adjusted, tighten the locking handwheel, and the warning board can be fixed at the current height under the action of friction.

[0021] In a possible implementation, support feet are welded to the bottoms of the side struts, anti-overturning members are arranged on the support feet, and the anti-overturning members include connecting ears welded to the support feet and ground plugs slidably arranged in the connecting ears.

[0022] With the above structural form, after the device is placed as a whole, the ground plug can be inserted into the muddy ground, and through the friction between it and the soil, the anti-overturning strength of the whole device can be enhanced, making the device have stronger wind resistance.

[0023] In summary, the utility model includes the following beneficial technical effects:

[0024] The warning board is used to display warning information and play a warning and reminder role. In strong wind weather, under the impact of the airflow, the disc will rotate and the pressure relief hole will be opened, and the airflow will pass through the pressure relief hole, thereby greatly reducing the wind load on the warning board and effectively preventing the whole device from deforming or being overturned.

[0025] And when the strong wind stops, under the reset action of the reset torsion spring and the mutual adsorption of the static adsorption magnet and the dynamic adsorption magnet, the disc will reset to cover the pressure relief hole, thereby avoiding affecting the viewing of the warning information on the warning board.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0034] Such as Figure 1 - Figure 3As shown, a safety warning device for a housing construction project provided in the present embodiment comprises a height-adjustable rotating bracket 1, on which a warning plate 2 with a pressure relief hole 21 is installed, warning information is sprayed on the warning plate 2, and a pressure relief member 3 is rotatably arranged in the pressure relief hole 21, wherein a rotating groove 22 is arranged on the warning plate 2, and the rotating groove 22 is arranged at the upper and lower sides of the pressure relief hole 21, the pressure relief member 3 comprises a disc 31 which matches the size of the pressure relief hole 21, and the upper and lower ends of the disc 31 are fixedly connected with a rotating shaft 32, and the rotating shaft 32 is rotatably arranged in the rotating groove 22, through the above-mentioned structural form, the warning plate 2 displays the warning information to play the role of warning reminder, in windy weather, under the impact of airflow, the disc 31 will rotate so that the pressure relief hole 21 is opened, and the airflow will pass through the pressure relief hole 21, thereby greatly reducing the wind load on the warning plate 2, which can effectively prevent the device from being deformed or overturned as a whole, and when the strong wind stops, the disc 31 will reset to cover the pressure relief hole 21 to avoid affecting the viewing of the warning information.

[0035] like Figure 3 As shown, the longitudinal section of the rotating shaft 32 is I-shaped, and a reset torsion spring 33 is provided on the outer sleeve of the inner concave section thereof, the bottom end of the reset torsion spring 33 is fixedly connected to the rotating shaft 32, and the top end of the reset torsion spring 33 is fixedly connected to the groove wall of the rotating groove 22. Through the above-mentioned structural form, when the disc 31 is affected by the airflow and rotates, it will drive the rotating shaft 32 to rotate, so that elastic potential energy is accumulated in the reset torsion spring 33. When the wind stops or the wind speed is significantly reduced, under the action of the reset torsion spring 33, the disc 31 will rotate to reset and cover the pressure relief hole 21, so as to display the warning information.

[0036] like Figure 3 As shown, the pressure relief hole 21 is provided with a first magnet mounting groove 23 on both sides, and a static adsorption magnet 24 is installed in the first magnet mounting groove 23. The disc 31 is provided with a second magnet mounting groove 35 on both sides, and a dynamic adsorption magnet 36 is installed in the second magnet mounting groove 35. Since the reset torsion spring 33 relies on elastic potential energy to reset, it is difficult to ensure that the disc 31 can be completely reset every time. The reset torsion spring 33 can usually only restore the disc 31 to an approximate position. At this time, under the mutual adsorption action of the static adsorption magnet 24 and the dynamic adsorption magnet 36, the rotation amplitude of the disc 31 can be further adjusted so that it can be reset as completely as possible.

[0037] Among them, after the static adsorption magnet 24 is installed and fixed, its N pole faces upward, and after the dynamic adsorption magnet 36 is installed and fixed, its S pole faces upward. This structural form can ensure that a positive and non-biased adsorption force can be generated between the static adsorption magnet 24 and the dynamic adsorption magnet 36, and the auxiliary disc 31 is completely reset.

[0038] like Figure 3As shown in the figure, a number of side slot holes 34 arranged on the left side are provided on the front end face of the disc 31, and the same number of side slot holes 34 arranged on the left side are provided on the rear end face of the disc 31. Through the above structural form, the opened side slot holes 34 can have a stronger blocking effect on the air flow, so that one side of the disc 31 can be subjected to a greater wind thrust, avoiding the extreme situation where the wind loads on both sides are the same, resulting in the disc 31 being unable to rotate.

[0039] As Figure 4 shown in the figure, the height-adjustable rotating bracket 1 includes side struts 11. An installation frame 12 is slidably arranged between the side struts 11, and a warning board 2 is installed in the installation frame 12. Through the above structural form, the adjustment of the installation height of the warning board 2 can be realized. In addition, a chute 111 is provided on the side strut 11, and position fixing screws 13 are fixedly arranged on both sides of the installation frame 12. The position fixing screws 13 are slidably arranged in the chute 111, and a locking handwheel 131 is threadedly connected to the end of the position fixing screw 13. When adjusting the installation height of the warning board 2, the position fixing screws 13 will slide synchronously in the chute 111. After the height of the warning board 2 is adjusted, tighten the locking handwheel 131, and the warning board 2 can be fixed at the current height under the action of friction.

[0040] As Figure 4 - Figure 5 shown in the figure, a support foot 14 is welded to the bottom of the side strut 11, and an anti-overturning member 15 is provided on the support foot 14. The anti-overturning member 15 includes a connecting ear 151 welded to the support foot 14 and a ground plug 152 slidably arranged in the connecting ear 151. Through the above structural form, after the device is integrally placed, the ground plug 152 can be inserted into the muddy ground, and through the friction force between it and the soil, the anti-overturning strength of the device as a whole can be enhanced, making the device have stronger wind resistance.

[0041] The working principle and working process of the present utility model:

[0042] The warning board 2 is used to display warning information to play a warning and reminder role. In strong wind weather, under the impact of the air flow, the disc 31 will rotate to open the pressure relief hole 21, and the air flow will pass through the pressure relief hole 21, thereby greatly reducing the wind load on the warning board 2, and effectively preventing the device as a whole from being deformed or overturned.

[0043] When the disc 31 rotates under the influence of the air flow, it will drive the rotating shaft 32 to rotate, so that elastic potential energy is stored in the reset torsion spring 33. When the wind stops or the wind speed significantly decreases, under the action of the reset torsion spring 33, the disc 31 will rotate back to its original position and cover the pressure relief hole 21, facilitating the display of warning information.

[0044] In addition, since the reset torsion spring 33 plays a reset role by elastic potential energy, it is difficult to ensure that the wafer 31 can be fully reset every time. The reset torsion spring 33 can usually only restore the wafer 31 to an approximate position. At this time, under the mutual adsorption of the static adsorption magnet 24 and the dynamic adsorption magnet 36, the rotation amplitude of the wafer 31 can be further adjusted to enable it to be fully reset as much as possible.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
