DETAILED DESCRIPTION

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] A highway bridge load limit intelligent warning device, such as Figure 1-Figure 5 As shown, it comprises a support assembly 1, a control box 2 fixedly connected to the support assembly 1, a display screen 3, a speaker 4 and a brushing mechanism 7 for cleaning the display screen 3 arranged on the front of the control box 2, an alarm mechanism 6 arranged on the back of the control box 2, a sensor for controlling the speaker 4 and the alarm mechanism 6 to operate is arranged on the control box 2, and a synchronization mechanism 8 for driving the brushing mechanism 7 to operate is arranged on the control box 2;

[0024] like Figure 2-Figure 3As shown, the warning mechanism 6 includes a first bracket 61 arranged on the back of the control box 2, a driving member arranged on the first bracket 61, a swing plate 63 arranged on the output shaft of the driving member, and a plurality of light strips 64 arranged on the swing plate 63. The sensor is a humidity sensor 5 for sensing whether it is raining. The driving member is a motor 62, and the output shaft of the motor 62 is connected to the swing plate 63. The motor 62 starts its output shaft to perform reciprocating swinging rotation.

[0025] It can be understood that the display screen 3 on the control box 2 is used to display the bridge load limit information. When encountering rainy days with low visibility, the humidity sensor 5 will sense that the humidity of the environment has increased. At this time, the humidity sensor 5 will control the display screen 3 to increase the brightness, so that the bridge load limit information is easy for people to watch, and the humidity sensor 5 will also control the speaker 4 to sound an alarm, so that vehicles on the road will check the display screen 3. The humidity sensor 5 will also control the motor 62 and the light bar 64 to start. When the motor 62 is started, its output shaft will reciprocate. The reciprocating rotation of the output shaft of the motor 62 will drive the swing plate 63 to swing back and forth. The reciprocating swing of the swing plate 63 will drive the light bar 64 thereon to swing. The strip 64 emits a warning light, and during the swinging process, vehicles on the road can look towards the display screen 3, thereby effectively reminding passing drivers to pay attention to the load limit of the bridge. At the same time, when the swing plate 63 swings, the synchronous mechanism 8 will drive the brushing mechanism 7 to wipe the display screen 3 to prevent rain from being adsorbed on the display screen 3, resulting in passing vehicles being unable to clearly see the bridge load limit information. When the environment is in a relatively low humidity, that is, the environment is sunny and the visibility is high, the humidity sensor 5 senses that the humidity is low, and will control the brightness of the display screen 3 to decrease, and will also control the motor 62, the speaker 4, and the light strip 64 to turn off, thereby saving power and reducing costs.

[0026] like Figure 1 As shown, the support assembly 1 includes a base plate 11 , a column 12 arranged on the base plate 11 , and two ribs 13 respectively arranged between two sides of the column 12 and two sides of the base plate 11 .

[0027] Among them, the bottom plate 11 is used to achieve a firm fixation with the ground, the column 12 is used to install the control box 2, so that the control box 2 is placed at a high point away from the ground, which is convenient for passing vehicles to check the load limit information, and the two ribs 13 are used to stabilize the column 12 to prevent the column 12 from collapsing due to instability.

[0028] like Figure 4 As shown, the brushing mechanism 7 includes a fixing member 71 arranged on the control box 2, a wiping plate 72 rotatably connected to the fixing member 71, an extending member 73 arranged on one side of the wiping plate 72, and a torsion spring 74 arranged between the fixing member 71 and the wiping plate 72.

[0029] It can be understood that the synchronization mechanism 8 will pull the extension piece 73 to swing upward, and the upward swing of the extension piece 73 will drive the wiping plate 72 to swing in the direction of the display screen 3. The wiping plate 72 wipes the display screen 3 to wipe off the rain water on the display screen 3, so that passing vehicles can check the display screen 3. The torsion spring 74 is deformed. When the synchronization mechanism 8 no longer pulls the extension piece 73, the torsion spring 74 will drive the wiping plate 72 to reset, thereby realizing the wiping work of the display screen 3.

[0030] like Figure 5 As shown, the synchronization mechanism 8 includes a second bracket 81 arranged on the control box 2, a winding wheel 82 rotatably connected to the second bracket 81, and a pull rope 83 wound on the winding wheel 82, one end of the pull rope 83 is connected to the swing plate 63, and the other end is connected to the extension member. The swing of the swing plate 63 will drive the extension member to swing through the pull rope 83.

[0031] It can be understood that when the motor 62 controls the swing plate 63 to move downward, the swing plate 63 will pull one end of the pull rope 83 to move downward, and the other end of the pull rope 83 will pull the extension piece 73 to swing upward, thereby the wiping plate 72 wipes the display screen 3; when the swing plate 63 is controlled by the motor 62 to swing upward, the swing plate 63 will relax the pull rope 83, and the pull rope 83 will relax and no longer pull the extension piece 73, and the wiping plate 72 will be reset through the torsion spring 74, thereby the swing plate 63 swings through the synchronization mechanism 8 to make the wiping plate 72 wipe the display screen 3, so that the functions of the two are synchronized to achieve the effect of convenient operation.

[0032] A solar panel 9 is disposed on the upper portion of the control box 2 , and the solar panel 9 is disposed obliquely on the upper portion of the control box 2 .

[0033] The solar panel 9 can convert light energy into electrical energy to charge the utility model. A power storage module is provided inside the control box 2, and the electrical energy converted from solar energy is stored in the power storage module.

[0034] To summarize, the humidity sensor 5 controls the speaker 4 to sound an alarm, reminding vehicles on the road to check the display screen 3 and pay attention to the bridge load limit. At the same time, the humidity sensor 5 will also control the motor 62 and the light bar 64 to start. When the motor 62 is started, its output shaft will rotate back and forth. The reciprocating rotation of the output shaft of the motor 62 will drive the swing plate 63 to swing back and forth. The reciprocating swing of the swing plate 63 will drive the light bar 64 thereon to swing. The light bar 64 emits a warning light, and during the swinging process, vehicles on the road can look at the display screen 3, further effectively reminding passing drivers to pay attention to the bridge load limit. The swing plate 63 swings, and the wiping plate 72 will wipe the display screen 3 through the synchronization mechanism 8, so as to wipe off the rain on the display screen 3 and make the load limit information on the display screen 3 clearly visible.
