Description

Technical Field

[0001] This invention relates to the field of highway safety protection technology, specifically to an intelligent safety protection device for highway construction workers. Background Technology

[0002] During the maintenance of highways and urban expressways, road maintenance workers frequently appear on various sections of the highway. During construction, these workers inevitably face safety threats from out-of-control vehicles, which can even lead to serious personal injury accidents. Although appropriate protective facilities have been placed in the work areas, cases of workers being injured or even killed still occur from time to time.

[0003] The existing protective facilities in construction areas are relatively simple, mainly serving as warnings to passing vehicles. Construction workers are mostly in a passive defensive situation, and if they encounter an out-of-control vehicle, they have little time to prepare for defense or avoid it. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent safety protection device for highway construction workers, so as to solve the problems existing in the prior art and help highway construction workers to take proactive defense.

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides an intelligent safety protection device for highway construction workers, comprising a base, a main shell, an airbag installed on one side of the main shell, an adhesive element installed on the other side of the main shell, a counterweight element and electronic components located inside the main shell, and an indicator light assembly and a position distance detection element installed on the outer wall of the main shell. The main shell is mounted on the upper end of the base. The indicator light assembly and the position distance detection element are both electrically connected to the electronic components. The electronic components integrate a collision sensor. The position distance detection element is used to detect the speed of passing vehicles and the distance between them and the main shell. The indicator light assembly is used to alert passing vehicles. In use, the airbag is located on the side of the construction worker, and the adhesive element is located on the side away from the construction worker.

[0007] Preferably, a plurality of pull rings are provided on each of the two opposite side walls of the main body shell, and the adjacent intelligent safety protection devices for highway construction workers are connected by iron chains and the pull rings, and the side wall where the pull rings are located is adjacent to the side wall where the airbag is located.

[0008] Preferably, the airbag has a slot on its outer periphery and a buckle on the back plate of the main body shell. The airbag and the main body shell are connected by the buckle being inserted into the slot.

[0009] Preferably, the adhesive element includes a plurality of rubber blocks, and the main body shell is provided with mounting grooves corresponding to the positions of each rubber block. The rubber blocks are fixed to the mounting grooves of the main body shell by mounting shells, and the rubber blocks are hollowed out.

[0010] Preferably, a telescopic rod is fixedly installed on the inner side of the rubber block, and a through hole is provided at the mounting groove. One end of the telescopic rod extends into the main body shell through the through hole. A telescopic spring is sleeved on the outer periphery of the telescopic rod. The two ends of the telescopic spring abut against the inner side of the rubber block and the bottom surface of the mounting groove, respectively. A telescopic sleeve is installed on the inner wall of the main body shell corresponding to the position of the telescopic rod, and one end of the telescopic rod can extend into the telescopic sleeve.

[0011] Preferably, the counterweight element includes an outer frame, several support rods, and several counterweight blocks. The outer frame is fixed inside the main body shell, and the outer frame has handle grooves for carrying on opposite sides. The support rods are installed inside the outer frame, and several counterweight springs and several counterweight blocks are sleeved on the support rods. The two ends of the counterweight spring located between two adjacent counterweight blocks abut against the two counterweight blocks respectively, and the two ends of the counterweight spring located between the counterweight blocks and the outer frame abut against the counterweight blocks and the outer frame respectively.

[0012] Preferably, the electronic components include a speaker, a circuit board component, and a battery component, and the speaker, the circuit board component, and the battery component are all electrically connected. The side wall of the main body shell is provided with honeycomb-shaped openings for sound transmission. The circuit board component integrates a collision sensor. When the position distance detection element detects that a vehicle is approaching, it transmits a signal to the circuit board component, and the circuit board component controls the speaker to broadcast information.

[0013] Preferably, the warning light assembly includes a strobe light, a solar photovoltaic panel, a laser rangefinder, a switch, a strobe light rear cover, and a strobe light front cover. The strobe light rear cover and the strobe light front cover are fastened together to form a cavity. The strobe light is located within the cavity. The strobe light includes a focusing sheet and LED matrix beads. The solar photovoltaic panel is electrically connected to the battery element. The laser rangefinder is installed on the side wall of the main body shell and is used to detect the distance to distant vehicles.

The switch is used to manually control the start and stop of the intelligent safety protection device for highway construction personnel.

[0014] Preferably, reflective strips are installed on each outer side wall of the main body shell.

[0015] Preferably, the lower end of the base is made of a friction-resistant material.

[0016] The present invention achieves the following technical effects compared to the prior art:

[0017] 1. This invention provides safety protection for construction workers. When the electronic components detect a collision with an out-of-control vehicle, they send an activation signal to the airbag module, causing the airbag to deploy and protect the construction workers. In use, multiple intelligent safety protection devices for highway construction workers are connected by chains. A vehicle collision will first cause one intelligent safety protection device to move. Due to the chain connection, the intelligent safety protection devices on both sides of it will also be dragged and detect the collision, simultaneously deploying the airbags. This allows multiple intelligent safety protection devices to cover the front and sides of the out-of-control vehicle, thereby increasing the protection of the construction workers.

[0018] 2. This invention enables "adhesive" vehicle braking assistance. When a car collides with the intelligent safety protection device for road construction workers, the rubber block contacts the vehicle surface. Simultaneously, as the car drags, the rubber block tightens its contact with the vehicle surface, generating strong friction. This allows the intelligent safety protection device to "adhere" to the vehicle. Furthermore, due to the chain connection, when a car drags one intelligent safety protection device, it will inevitably pull the others. At this time, the friction between the base and the ground helps increase the braking force of the car, accelerating the braking process and thus protecting the construction workers. The deployed airbags also protect the out-of-control vehicle to a certain extent, providing a buffer when the out-of-control vehicle hits the final obstacle, effectively reducing driver injury and vehicle damage.

[0019] 3. This invention can match the weight of different vehicles by placing different counterweights, thereby adapting to different lanes; and counterweight springs are set between the counterweights to absorb the kinetic energy transmitted to the intelligent safety protection device for road construction workers when an out-of-control vehicle crashes into it, thereby reducing the distance the intelligent safety protection device for road construction workers is thrown away by an out-of-control vehicle; furthermore, the counterweights can increase the weight of the intelligent safety protection device for road construction workers, thereby increasing the friction between the intelligent safety protection device for road construction workers and the ground. The counterweights can also be replaced by liquid, and the vehicle weight can be matched by injecting liquid.

[0020] 4. This invention is equipped with multiple warning devices to cope with different times and scenarios: in good weather, it can use flashing lights and a voice system to warn passing vehicles; at night, it can use flashing lights, reflective strips and a voice system in combination to warn passing vehicles; in addition, the voice system can also be used to warn construction workers whether there are vehicles approaching.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The purpose of this invention is to provide an intelligent safety protection device for highway construction workers, so as to solve the technical problem that existing highway construction protection devices lack active defense functions.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-5 As shown, this embodiment provides a smart safety protection device for highway construction workers. In use, multiple smart safety protection devices for highway construction workers are connected to form an integrated protection system. The smart safety protection device for highway construction workers includes a base 6, a main shell, an airbag 12 installed on one side of the main shell, an adhesive element installed on the other side of the main shell, a counterweight element 2 and an electronic component 1 located inside the main shell, and an indicator light assembly 3 and a position distance detection element installed on the outer wall of the main shell. The main shell is mounted on the upper part of the base 6. The indicator light assembly 3 and the position distance detection element are both electrically connected to the electronic component 1. The electronic component 1 also integrates a collision sensor. The position distance detection element is used to detect the speed of passing vehicles and the distance between the vehicle and the main shell. The indicator light assembly 3 is used to alert passing vehicles. The airbag 12 is located on the side of the construction worker, while the adhesive element is located on the side away from the construction worker, effectively "sticking" the vehicle to assist in braking. Simultaneously, the counterweight element 2 increases weight, friction, and braking force. Upon collision, the collision sensor sends an activation signal to the airbag 12 module, causing it to deploy and protect the construction worker. Furthermore, the collision will first cause one of the road construction worker safety intelligent protection devices to move. Because adjacent road construction worker safety intelligent protection devices are connected, the devices on either side of it will also detect the collision and deploy the airbag 12, thus allowing multiple road construction worker safety intelligent protection devices to surround the front and sides of the out-of-control vehicle, thereby increasing protection for the construction worker.

[0032] Specifically, several pull rings 5 ​​are provided on the two opposite side walls of the main body shell. Adjacent intelligent safety protection devices for highway construction workers are connected by iron chains and pull rings 5 ​​to form an overall protection system. The side wall where the pull rings 5 ​​are located is adjacent to the side wall where the airbag 12 is located. Preferably, there are three pull rings 5 ​​on each side of the main body shell.

[0033] The top of the main casing also has an opening for placing electrical connection wires.

[0034] The airbag 12 has a slot on its outer periphery, and the back plate of the main body shell has an "U"-shaped groove. Buckles are located on both sides of the "U"-shaped groove, and the airbag 12 is connected to the main body shell by the buckles fitting into the slot. As a preferred embodiment, a storage plate is provided on one side of the airbag 12, and the storage plate is detachable from the main body shell.

[0035] The adhesive element includes multiple rubber blocks 4. The main body shell has mounting grooves corresponding to the positions of each rubber block 4. The rubber blocks 4 are fixed to the mounting grooves of the main body shell through the mounting shell 7. The rubber blocks 4 are hollowed out to increase the contact area with the car surface when squeezed, so that the rubber blocks 4 can better fit the car surface.

[0036] As other preferred options, the adhesive element can also be replaced with materials with strong adhesion, such as fiber gel or self-adhesive silicone strips.

[0037] A telescopic rod 17 is fixedly installed on the inner side of the rubber block 4. A through hole is provided at the mounting groove, preferably four through holes. One end of the telescopic rod 17 extends into the main body shell through the through hole. A telescopic spring 18 is sleeved on the outer periphery of the telescopic rod 17. The two ends of the telescopic spring 18 abut against the inner side of the rubber block 4 and the bottom surface of the mounting groove, respectively. A telescopic sleeve 16 is installed on the inner wall of the main body shell at the position corresponding to the telescopic rod 17. One end of the telescopic rod 17 can extend into the telescopic sleeve 16. With the setting of the telescopic spring 18, the rubber block 4 has a certain amount of expansion and contraction when a collision occurs, which can also play a role in buffering and energy dissipation.

[0038] The counterweight element 2 includes an outer frame 21, several support rods 23, and several counterweight blocks 24. The outer frame 21 is fixed inside the main body shell, and handle grooves for carrying are provided on opposite sides of the outer frame 21 to facilitate the removal of the counterweight element 2. The support rods 23 are installed inside the outer frame 21, and several counterweight springs 22 and several counterweight blocks 24 are sleeved on the support rods 23. The two ends of the counterweight springs 22 located between two adjacent counterweight blocks 24 abut against the two counterweight blocks 24 respectively, and the two ends of the counterweight springs 22 located between the counterweight blocks 24 and the outer frame 21 abut against the counterweight blocks 24 and the outer frame 21 respectively. Thus, when subjected to a vehicle collision, the counterweight blocks 24 can reciprocate axially with the support rods 23 under the action of the counterweight springs 22, thereby dissipating the collision energy. To reduce manufacturing costs, the counterweight blocks in this embodiment can also be replaced with liquid, thereby achieving the same effect through the sloshing of the liquid.

[0039] Limiting grooves are provided on the two opposite inner sidewalls of the main body shell, and limiting protrusions are provided on the two opposite outer sidewalls of the outer frame 21. The limiting protrusions are embedded in the limiting grooves to limit the outer frame 21.

[0040] Electronic component 1 includes a speaker 11, a circuit board component, and a battery component, all of which are electrically connected. The side wall of the main casing has honeycomb-shaped openings for sound transmission. The circuit board component integrates a collision sensor; when a vehicle approaches, the position distance detection element transmits a signal to the circuit board component, which then controls the speaker 11 to broadcast information. The circuit board bracket 14 in the circuit board component is supported and fixed by a bracket composed of four copper pillars. The battery bracket 15 in the battery component is used to fix the lithium battery. The speaker 11 includes two symmetrically arranged components.

[0041] The warning light assembly 3 includes a strobe light, a solar photovoltaic panel 33, a laser rangefinder 34, a switch 35, a strobe light rear cover 36, and a strobe light front cover 37. The strobe light rear cover 36 and the strobe light front cover 37 are fastened together to form a cavity, and are connected by bolts. The strobe light is located inside the cavity and includes a focusing sheet 31 and LED matrix beads 32 to increase the strobe light warning distance. The solar photovoltaic panel 33 is electrically connected to the battery element and is used to convert solar energy into electrical energy, saving energy. The laser rangefinder 34 is installed on the side wall of the main body shell and is used to detect the distance of distant vehicles. The position distance detection element is an infrared sensor 19, which is used to detect the distance of nearby vehicles. Preferably, there are three infrared sensors 19, which are fixed to the main body shell by two sensor nuts 13. The type of sensor is adjusted according to the placement of the main body shell to save manufacturing costs. The switch 35 is used to manually control the start and stop of the intelligent safety protection device for highway construction personnel.

[0042] Reflective strips are installed on each outer wall of the main body shell, which can reflect vehicle lights at night to alert passing vehicles.

[0043] The lower end of the base 6 is made of a friction-resistant material, which increases the friction between the base 6 and the ground, thereby increasing the braking force of the car during a collision.

[0044] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be construed as a limitation of the present invention.
