Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety, and in particular to a traffic safety warning device and a method of using the same. Background Art

[0002] During road construction, traffic safety warning devices are usually placed at the construction site. The traffic safety warning devices are equipped with reflective warning signs and warning lights to alert passing vehicles and pedestrians. However, some existing traffic safety warning devices can only use warning signs and warning lights to warn passing pedestrians and vehicles, but cannot give sound warnings to passing pedestrians and vehicles.

[0003] Some traffic safety warning devices are equipped with a module that can emit warning sounds. The warning sound generally needs to be maintained at a higher frequency in order to improve the warning effect. As the outside temperature is higher, the sound propagates faster. When the outside temperature is low, the sound propagates slower. That is, for the same sound frequency, the sound frequency heard by the human ear will change with the temperature. That is, if the sound frequency is constant, when the temperature is low, the sound frequency of the warning sound heard by pedestrians or drivers decreases, that is, the time interval between multiple warning sounds heard by the human ear becomes larger, resulting in a weakened overall warning effect of the warning sound, which cannot provide a good warning effect for the driver and may cause a safety accident. Summary of the invention

[0004] The technical problem to be solved by the present invention is a traffic safety warning device which can automatically adjust the sound frequency according to the external temperature and a method of using the same.

[0005] In order to achieve the above object, the technical solution provided by the present invention is:

[0006] The traffic safety warning device comprises a box body, which is fixed on a support frame, a slot is opened on one side of the box body, a reciprocating screw is rotatably arranged at the upper end inside the box body, a driving component for driving the reciprocating screw to rotate is arranged on the outer side of the box body, a striking component is sleeved on the reciprocating screw, the striking component is slidably connected with the box body, and when the reciprocating screw rotates, the striking component can reciprocate on the reciprocating screw, a sliding rod is fixed in the box body below the reciprocating screw, the sliding rod is parallel to the reciprocating screw, a plurality of connecting rods are evenly distributed and slidably connected on the sliding rod along its length direction, a metal rod for making a sound is fixed on the upper end of the connecting rod, and the striking component can be reciprocated on the reciprocating screw when the reciprocating screw rotates. When the striking assembly moves in the axial direction of the reciprocating screw, it can strike multiple pronunciation metal rods in sequence. A limit plate is slidably arranged in the box body. The sliding direction of the limit plate is perpendicular to the length direction of the sliding rod. A limit groove corresponding to the connecting rod is opened on the limit plate. The lower ends of the multiple limit grooves are evenly emitted and dispersed. Bumps are fixed on the connecting rod. The multiple bumps are respectively slidably arranged in the multiple limit grooves. A lifting rod is fixed on the limit plate. The lifting rod is concentrically slidably sealed and inserted in the cylinder body. The cylinder body is fixedly connected to the box body. A medium that can expand and contract with heat and cool is filled between the lifting rod and the cylinder body.

[0007] Specifically, a cover plate is detachably fixedly connected to one side of the box body, a slot hole is provided on the cover plate, the slot hole is a speaker hole, and a mesh cover is fixed in the slot hole.

[0008] Specifically, the reciprocating screw is arranged horizontally, and the driving assembly includes a motor, the motor is fixed on the box, and the output shaft of the motor is coaxially fixedly connected with the reciprocating screw.

[0009] Specifically, a vertical slide groove is opened in the box body, the limit plate is slidably arranged in the slide groove, the end face of the slide rod is inverted T shape, and a card block is fixed on the connecting rod, the card block is slidably connected to the slide rod, and the distance between the upper ends of two adjacent limit grooves is smaller than the distance between the lower ends.

[0010] Specifically, the medium that expands with heat and contracts with cold is kerosene.

[0011] Specifically, a distance sensor is installed on the outside of the box, and a controller and a power supply are installed inside the box. The power supply, the controller, the distance sensor and the motor are electrically connected.

[0012] Specifically, the upper end of the lifting rod is fixedly connected to the lower end of the limiting plate, the lifting rod is vertically arranged, and the medium that expands and contracts with heat and contracts with cold is located between the lower end of the lifting rod and the lower end of the cylinder.

[0013] Specifically, the striking assembly includes a connecting block, which is slidably arranged in a box body, and a reciprocating screw passes through the connecting block. The reciprocating screw, the connecting block and the balls in the connecting block constitute a reciprocating ball screw pair. A striking rod is rotatably connected to the connecting block through a pin shaft, and a torsion spring is sleeved on the pin shaft. One end of the torsion spring is fixedly connected to the connecting block, and the other end of the torsion spring is fixedly connected to the striking rod.

[0014] When in use, the device is placed on a road section that needs construction, and the driving component drives the reciprocating screw to rotate, and the reciprocating screw causes the connecting block to reciprocate in the box. During the reciprocating movement of the connecting block, the knocking rod on the connecting block knocks on multiple pronunciation metal rods in sequence; when the knocking rod knocks on the first pronunciation metal rod, the knocking force of the knocking rod on the first pronunciation metal rod is relatively small, and the warning volume emitted when the knocking rod knocks on the first pronunciation metal rod is relatively low. With the movement of the knocking rod, the knocking rod rotates elastically under the blocking effect of the first pronunciation metal rod. After the striking rod is separated from the first pronunciation metal rod, the striking rod quickly rotates to restore and strikes the second pronunciation metal rod. The striking force of the striking rod on the second pronunciation metal rod is greater, and the warning volume emitted when the striking rod strikes the second pronunciation metal rod increases. During the movement of the connecting block and the striking rod, the striking force of the striking rod on other pronunciation metal rods is greater than the striking force of the striking rod on the first pronunciation metal rod. The warning sound emitted when the striking rod strikes the pronunciation metal rod can warn pedestrians and drivers near the construction section to avoid traffic accidents.

[0015] When the outside temperature is low, the sound propagation speed is slow, the medium in the cylinder that expands and contracts due to heat and cold shrinks, and the lifting rod moves downward. When the lifting rod moves downward, it drives the limit plate to slide downward. Under the guiding effect of the limit groove opened on the limit plate on the protrusion, when the limit plate slides downward, multiple connecting rods shrink equidistantly, and the spacing between multiple sound-producing metal rods decreases. At this time, during the movement of the knocking rod, the interval time between the knocking rod knocking the sound-producing metal rod is reduced, that is, the frequency of the warning sound emitted is increased, thereby ensuring the sound frequency of the device in a low temperature environment, which can have a better warning effect on the driver and increase safety.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device sets a medium that expands and contracts with heat between the lifting rod and the cylinder. When the outside temperature is low, the limit plate moves downward to reduce the distance between the multiple sound-generating metal rods. During the movement of the knocking rod, the interval time between the knocking rod and the sound-generating metal rod is reduced, that is, the frequency of the warning sound is increased, thereby ensuring the sound frequency of the device in a low temperature environment, which is convenient for providing a better warning effect to the driver and increasing safety.

[0018] 2. By setting a distance sensor, when a pedestrian or driver approaches the device, the device is activated and the warning sound is propagated at a suitable frequency, which can automatically warn the pedestrian or driver. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figure 1-Figure 6 As shown, the traffic safety warning device comprises a box body 1, which is fixed on a support frame 4, and a slot 15 is provided on one side of the box body 1.

The slot 15 is a speaker hole, and a mesh cover 3 is fixed in the slot 15. The slot 15 is provided to facilitate the warning sound in the box body 1. The mesh cover 3 can prevent dust from entering the box body 1.

[0028] A reciprocating screw 5 is rotatably arranged at the upper end of the box body 1, and a driving assembly for driving the reciprocating screw 5 to rotate is arranged on the outer side of the box body 1. The reciprocating screw 5 is arranged horizontally, and the driving assembly includes a motor 16, which is fixed on the box body 1, and the output shaft of the motor 16 is concentrically fixedly connected with the reciprocating screw 5. After starting the motor 16, the reciprocating screw 5 can rotate.

[0029] A striking assembly is sleeved on the reciprocating screw 5 , and the striking assembly is slidably connected to the box body 1 . When the reciprocating screw 5 rotates, the striking assembly can reciprocate on the reciprocating screw 5 .

[0030] The striking assembly includes a connecting block 18, which is slidably arranged in the box body 1, and the reciprocating screw 5 passes through the connecting block 18. The reciprocating screw 5, the connecting block 18 and the balls in the connecting block 18 constitute a reciprocating ball screw pair. The connecting block 18 is rotatably connected to a striking rod 19 through a pin shaft, and a torsion spring is sleeved on the pin shaft, one end of the torsion spring is fixedly connected to the connecting block 18, and the other end of the torsion spring is fixedly connected to the striking rod 19.

[0031] A slide bar 9 is fixed in the box 1 below the reciprocating screw 5, and the slide bar 9 is parallel to the reciprocating screw 5. A plurality of connecting rods 7 are evenly slidably connected to the slide bar 9 along its length. Specifically, the end face of the slide bar 9 is in an inverted T shape, and a clamping block 8 is fixed on each connecting rod 7, and the clamping block 8 is slidably connected to the slide bar 9.

[0032] A sound-generating metal rod 6 is fixed to the upper end of each connecting rod 7 , and the striking assembly can strike a plurality of sound-generating metal rods 6 in sequence when the striking assembly moves in the axial direction of the reciprocating screw 5 .

[0033] A limit plate 12 is slidably disposed in the box body 1. Specifically, a vertical slide groove 17 is provided in the box body 1, and the limit plate 12 is slidably disposed in the slide groove 17, and the sliding direction of the limit plate 12 is perpendicular to the length direction of the slide rod 9.

[0034] The limiting plate 12 is provided with limiting grooves 11 corresponding to the connecting rod 7, and the lower ends of the plurality of limiting grooves 11 are evenly dispersed. Specifically, the distance between the upper ends of two adjacent limiting grooves 11 is smaller than the distance between the lower ends.

[0035] The connecting rods are all fixed with protrusions 10 , and the multiple protrusions 10 are slidably arranged in the multiple limiting grooves 11 .

[0036] A lifting rod 13 is fixed on the limit plate 12 , the upper end of the lifting rod 13 is fixedly connected to the lower end of the limit plate 12 , the lifting rod 13 is vertically arranged, and the lifting rod 13 is concentrically slidably sealed and inserted in the cylinder 14 , and the cylinder 14 is fixedly connected to the box body 1 .

[0037] A medium capable of thermal expansion and contraction is filled between the lifting rod 13 and the cylinder 14. Specifically, the medium capable of thermal expansion and contraction is located between the lower end of the lifting rod 13 and the lower end of the cylinder 14, and the medium capable of thermal expansion and contraction is kerosene.

[0038] A distance sensor is installed on the outside of the box 1, and a controller and a power supply are installed in the box 1. The power supply, the controller, the distance sensor and the motor 16 are electrically connected.

[0039] The device is placed on a road section that needs construction. When the distance sensor detects a pedestrian or a vehicle, the distance sensor starts the motor 16 through the controller. The motor 16 drives the reciprocating screw 5 to rotate at a constant speed. The reciprocating screw 5 causes the connecting block 18 to reciprocate in the box body 1. During the reciprocating movement of the connecting block 18, the knocking rod 19 on the connecting block 18 knocks on multiple sound-generating metal rods 6 in turn.

[0040] When the knocking rod 19 knocks the first pronunciation metal rod 6, the knocking force of the knocking rod 19 on the first pronunciation metal rod 6 is small, and the warning volume emitted when the knocking rod 19 knocks the first pronunciation metal rod 6 is low. As the knocking rod 19 moves, the knocking rod 19 rotates under the blocking effect of the first pronunciation metal rod 6, and the torsion spring accumulates force. After the knocking rod 19 is separated from the first pronunciation metal rod 6, the knocking rod 19 quickly rotates to restore and knocks the second pronunciation metal rod 6. The knocking force of the knocking rod 19 on the second pronunciation metal rod 6 is large, and the warning volume emitted when the knocking rod 19 knocks the second pronunciation metal rod 6 increases.

[0041] During the movement of the connecting block 18 and the knocking rod 19 , the knocking force of the knocking rod 19 on the other sound-generating metal rods 6 is greater than the knocking force of the knocking rod 19 on the first sound-generating metal rod 6 .

[0042] The warning sound emitted when the knocking rod 19 knocks the sound-generating metal rod 6 can warn pedestrians or drivers near the construction section to avoid traffic accidents.

[0043] When the outside temperature is low, the sound propagation speed is slow, the medium in the cylinder 14 shrinks due to thermal expansion and contraction, and the lifting rod 13 moves downward. When the lifting rod 13 moves downward, it drives the limit plate 12 to slide downward. Under the guiding effect of the limit groove 11 provided on the limit plate 12 on the protrusion 10, the multiple connecting rods 7 shrink equidistantly, and the spacing between the multiple sounding metal rods 6 decreases. At this time, during the movement of the knocking rod 19, the interval time between the knocking rod 19 knocking the multiple sounding metal rods 6 is reduced, that is, the sound frequency of the warning sound emitted is increased, so as to ensure the sound frequency of the device in a low temperature environment, and can play a better warning effect on pedestrians or drivers, thereby increasing safety.

[0044] The above description is only a preferred embodiment of the present invention and is 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.
