Description

Technical Field

[0001] The invention belongs to the technical field of traffic lights, in particular to an emergency traffic signal light. Background Art

[0002] Emergency traffic lights, commonly known as temporary traffic lights or mobile traffic lights, are mainly used to provide traffic instructions and warnings to ensure traffic order and safety in temporary construction sections with heavy traffic, traffic accident sites, road maintenance areas and other places requiring temporary traffic control.

[0003] The Chinese invention application with application number CN202010889788.1 discloses a mobile temporary traffic light for traffic safety, including a support frame, a support platform and a detachable light panel. The mobile temporary traffic light for traffic safety has a reasonable structure, is easy to install stably, is easy to adjust the height, and is easy to disassemble and repair the light, and has high practical value.

[0004] Although the above application solves the problems of difficult positioning, difficult adjustment of the height of the traffic light, and difficult regular disassembly, inspection and maintenance of the traffic light, the lamp body and the electronic components inside it will generate heat during use, so the heat is dissipated through the heat sink of the lamp body itself. However, in some environments with high temperatures, the heat sink of the lamp body alone cannot effectively dissipate the heat, so a cooling fan is used to blow external wind into the emergency traffic light to dissipate the heat of the lamp body. Although the heat dissipation method of the cooling fan can greatly improve the heat dissipation performance of the lamp body at high temperatures, when it rains, it may cause rainwater to enter the emergency traffic light from the cooling fan, causing the internal electronic components to become damp and damaged.

[0019] like Figures 1 to 7 As shown, an embodiment of the present invention provides an emergency traffic signal light, comprising a mobile base 1, a mounting shell 2 is fixedly connected to the top of the mobile base 1, a lamp body 3 is fixedly connected to the four sides of the mounting shell 2, and a wind cooling mechanism 4 is provided at the top of the mounting shell 2; A rainproof mechanism 5 is provided above the air cooling mechanism 4, and the rainproof mechanism 5 includes two spring assemblies 51, and the two spring assemblies 51 are respectively fixedly installed on both sides of the upper end of the installation shell 2, and the top of the spring assembly 51 is fixedly connected to a dry water collecting bin 52, and the top of the dry water collecting bin 52 is fixedly connected to a filter screen 53, and a quick-drying diatomaceous earth drying strip is placed in half of the inner cavity of the dry water collecting bin 52, and the bottom end of the dry water collecting bin 52 is fixedly connected to a water baffle 54, and the lower end of the water baffle 54 extends to the interior of the installation shell 2, and The water retaining plate 54 is slidably connected to the mounting shell 2, a telescopic tube 55 is fixedly connected to the center of the bottom of the dry water collecting bin 52, a shunt tube 56 is fixedly connected to the bottom of the telescopic tube 55, the top of the shunt tube 56 is fixedly connected to the top of the inner cavity of the mounting shell 2, a heat dissipation cavity plate 57 is fixedly connected to the bottom of the shunt tube 56, the heat dissipation cavity plate 57 is fitted with the lamp body 3 on one side of the inner cavity of the mounting shell 2, a drain pipe 58 is fixedly connected to the bottom end of the heat dissipation cavity plate 57, and the bottom end of the drain pipe 58 is located on the outside of the mounting shell 2; The air cooling mechanism 4 includes an air inlet cylinder 41, which is fixedly connected to one side of the upper end of the mounting shell 2 close to the water baffle 54, and the water baffle 54 is located above the air inlet cylinder 41; The spring assembly 1 51 is composed of a single damping telescopic rod 511 and a spring 1 512. The single damping telescopic rod 511 is located at the center of the inner cavity of the spring 1 512. The tops of the single damping telescopic rod 511 and the spring 1 512 are fixedly connected to the dry water collecting bin 52. The inner cavity of the air inlet cylinder 41 is fixedly connected with a blowing assembly 42, and the blowing assembly 42 is composed of a waterproof support frame 421, a micro motor 422, and a heat dissipation fan 423. The waterproof support frame 421 is fixedly connected to the inner cavity of the air inlet cylinder 41, and the micro motor 422 is fixedly connected to the inner cavity at the top of the waterproof support frame 421. The heat dissipation fan 423 is fixedly sleeved on the output shaft of the micro motor 422, and the air inlet cylinder 41 is connected with the inner cavity of the mounting shell 2; An air outlet 43 is provided at the center of the bottom end of the installation shell 2 , and the installation shell 2 is connected to the outside through the air inlet tube 41 and the air outlet 43 .

[0020] In this embodiment, in the initial state, the spring assembly 1 51 and the spring assembly 2 71 are both in a stress-free state, and the quick-drying diatom drying strip is located in the half of the inner cavity of the drying water collection bin 52. Then, after the mobile base 1 is moved to the designated position, the lamp body 3 is used for traffic control; When it is not raining, the micro motor 422 is started to drive the cooling fan 423 to rotate and generate wind force, and the external air is blown from the air inlet tube 41 to the inner cavity of the mounting shell 2, and the wind force is blown out from the air outlet 43, so that the inner cavity of the mounting shell 2 forms an air duct, thereby dissipating heat from the lamp body 3; When it rains, rainwater enters the inner cavity of the dry water collection bin 52 through the filter 53 and contacts the quick-drying diatom drying strips, so that the volume and weight of the quick-drying diatom drying strips increase, thereby driving the dry water collection bin 52 to descend, the spring assembly 1 51 contracts under force, and the telescopic tube 55 contracts. When the dry water collection bin 52 descends, the water baffle 54 above the air inlet tube 41 is driven to descend to block the air inlet tube 41, so that the air inlet tube 41 is blocked on rainy days to prevent rainwater from entering the inner cavity of the mounting shell 2, causing the lamp body 3 inside the mounting shell 2 to be damaged by moisture. When the quick-drying diatom drying strips are completely filled with water, excess rainwater flows along the telescopic tube 55 into the inner cavity of the shunt tube 56, and the rainwater is shunted by the shunt tube 56. The diverted rainwater enters the inner cavity of the heat dissipation cavity plate 57, and is fitted with the lamp body 3 through the heat dissipation cavity plate 57, so that the lamp body 3 is cooled by the rainwater flowing in the inner cavity of the heat dissipation cavity plate 57, and then the rainwater is discharged to the bottom of the mounting shell 2 through the drain pipe 58, so that when the air inlet 41 is blocked on rainy days and the external air cannot enter the inner cavity of the mounting shell 2 for heat dissipation, the lamp body 3 can still be cooled by the flowing rainwater.

[0021] like Figures 1 to 7 As shown, an embodiment of the present invention provides an emergency traffic signal light, a pulling mechanism 6 is provided at the top of the shunt pipe 56, the pulling mechanism 6 includes a lifting rack 61, the lifting rack 61 is fixedly connected to the bottom of the dry water collecting bin 52 and is located in the inner cavity of the mounting shell 2, an acceleration gear 62 is movably connected at a position above the inner cavity of the mounting shell 2 near the lifting rack 61, the lifting rack 61 and the acceleration gear 62 are meshed, a notched gear 63 is fixedly connected to the side of the acceleration gear 62 away from the lifting rack 61, a full gear 64 is movably connected to the side of the shunt pipe 56 away from the lifting rack 61, a winding drum 65 is fixedly connected to the side of the full gear 64 away from the shunt pipe 56, a pull rope plate 66 is fixedly connected to the inner cavity of the winding drum 65, and a steel wire 67 is fixedly connected to the bottom end of the pull rope plate 66; A cleaning mechanism 7 is arranged on the outside of the mounting shell 2, and the cleaning mechanism 7 includes a second spring assembly 71, which is fixedly connected to the top of the four sides of the mounting shell 2, and the second spring assembly 71 is located below the first spring assembly 51, and a cleaning frame 72 is fixedly connected to the bottom end of the second spring assembly 71, and a cleaning brush 73 is fixedly connected to the side of the cleaning frame 72 close to the lamp body 3, and the bottom end of the cleaning frame 72 is fixedly connected to the end of the steel wire 67 away from the pull rope plate 66; The notch gear 63 can rotate with the acceleration gear 62 as the axis. When the teeth of the notch gear 63 are close to the full gear 64, they mesh with the full gear 64. When the gap of the notch gear 63 is close to the full gear 64, it separates from the full gear 64. The bottom and the outer side of the inner cavity of the mounting shell 2 are fixedly connected with a support roller 68, and the steel wire 67 is sleeved in the inner cavity of the support roller 68; The spring assembly 2 71 is composed of a multi-stage damping telescopic rod 711 and a spring 2 712. The multi-stage damping telescopic rod 711 is located at the center of the inner cavity of the spring 2 712. The part of the lamp body 3 located outside the mounting shell 2 is located on the moving path of the cleaning brush 73, and the cleaning brush 73 is in contact with the outer surface of the mounting shell 2.

[0022] In this embodiment, when the dry water collection bin 52 is initially lowered, the lifting rack 61 is driven to lower, and the lifting rack 61 is meshed with the acceleration gear 62, thereby driving the acceleration gear 62 to rotate; The notched gear 63 is driven to rotate by the acceleration gear 62, and the gear teeth of the notched gear 63 contact and mesh with the full gear 64, driving the full gear 64 to rotate, and the full gear 64 drives the winding drum 65 to rotate to pull the bottom end of the rope plate 66 upward and wrap it around the inner cavity of the winding drum 65. When the bottom end of the rope plate 66 moves upward, the end of the steel wire 67 located in the inner cavity of the mounting shell 2 is pulled upward, and then the support roller 68 limits the position of the steel wire 67, so that the end of the steel wire 67 located outside the mounting shell 2 moves downward, and then the cleaning frame 72 is pulled downward. At this time, the spring assembly 2 71 is stretched by the tension, and the cleaning brush 73 moves downward. The cleaning brush 73 is attached to the outer surface of the mounting shell 2 and the lamp body 3 is located on the moving path of the cleaning brush 73, so that the cleaning brush 73 cleans the lamp body 3 when it moves in conjunction with the rainwater falling down; As the notch gear 63 rotates, when the vacant part of the notch gear 63 approaches the full gear 64, the notch gear 63 and the full gear 64 separate, and the winding drum 65 no longer rotates, causing the rope-pulling plate 66 to lose its upward pulling force. At this time, the spring assembly 2 71 loses the restriction of pulling force and shrinks upward to reset, thereby driving the cleaning frame 72 to move upward to reset. The cleaning frame 72 pulls the steel wire 67 to the outside of the mounting shell 2, and the bottom end of the rope-pulling plate 66 moves downward, driving the winding drum 65 and the full gear 64 to reverse, so that the rope-pulling plate 66 wound in the inner cavity of the winding drum 65 separates; The cleaning frame 72 is moved upward and reset to drive the cleaning brush 73 to clean the lamp body 3 again. As the dry water collection bin 52 gradually descends, the gear ratio between the acceleration gear 62 and the lifting rack 61 is used to drive the acceleration gear 62 to rotate multiple times during the descent of the lifting rack 61, thereby driving the notch gear 63 to rotate multiple times, so that the gear teeth of the notch gear 63 are meshed with the full gear 64 again, and the cleaning frame 72 is pulled downward, and the cycle is repeated. When it rains, the cleaning brush 73 can be lifted and lowered back and forth to clean the lamp body 3 with rain water, so that when the lamp body 3 is in an environment of rain and dust, the dust layer with strong adhesion on its surface can be effectively removed, thereby improving the recognition. When the rain stops, the quick-drying diatomaceous earth strips in the inner cavity of the dry water collection bin 52 can dry quickly within a few hours due to their own characteristics. The quick-drying diatomaceous earth strips after re-drying are reduced in volume and weight to the initial state, so that the gravity exerted on the spring component 51 is eliminated, thereby allowing the spring component 51 to drive the dry water collection bin 52 to move upward and reset, and then drive the water baffle 54 to move upward and reset to leave the air inlet pipe 41, thereby allowing external air to enter the inner cavity of the mounting shell 2 from the air inlet pipe 41.

[0023] Working principle and use process: In the initial state, the spring assembly 1 51 and the spring assembly 2 71 are in a stress-free state, then the mobile base 1 is moved to the designated position, then the traffic is directed through the lamp body 3, and the micro motor 422 is started to drive the cooling fan 423 to operate, and the rotation of the cooling fan 423 generates wind to blow toward the inner cavity of the installation shell 2, and the wind blown into the inner cavity of the installation shell 2 is discharged from the air outlet 43 to form an air duct to cool and dissipate the heat of the lamp body 3; When it rains, rainwater enters the inner cavity of the dry water collecting bin 52 from the filter screen 53, and contacts the dry strips in the inner cavity of the dry water collecting bin 52. The dry strips become heavier after absorbing rainwater, driving the dry water collecting bin 52 to descend, thereby driving the spring assembly 1 51 to contract, and driving the water baffle 54 to descend to block the air inlet cylinder 41, thereby preventing external rainwater from entering the inner cavity of the mounting shell 2 from the air inlet cylinder 41; When the dry water collecting bin 52 descends, the lifting rack 61 is driven to descend, and the lifting rack 61 is meshed with the acceleration gear 62, thereby driving the acceleration gear 62 to rotate, and the acceleration gear 62 drives the notch gear 63 to rotate. When the gear teeth of the notch gear 63 are meshed with the full gear 64, the full gear 64 drives the winding drum 65 to rotate and winds the pull rope plate 66 around the inner cavity of the winding drum 65, so that the bottom of the pull rope plate 66 rises, and the pull rope plate 66 drives the steel wire 67 to rise, and then the support roller 68 limits the position of the steel wire 67, so that when the steel wire 67 rises, it pulls the cleaning frame 72 downward, and at this time, the spring assembly 2 71 is subjected to the tension and begins to stretch, and the cleaning frame 72 descends and drives the cleaning brush 73 to wipe the outer surface of the lamp body 3. When the notch of the notch gear 63 is close to the full gear 64, the notch gear 63 and the full gear 64 are separated, and the full gear 64 can no longer drive the winding drum 65 to rotate, so that the cleaning frame 72 loses the tension restriction, and then the spring assembly 2 71 loses the tension restriction, starts to contract, drives the cleaning frame 72 to move upward and reset, pulls the steel wire 67 to the outside of the mounting shell 2, and pulls down the rope plate 66 wound on the surface of the winding drum 65 through the steel wire 67; The cleaning brush 73 is driven upward by the cleaning frame 72 to wipe the outer surface of the lamp body 3 again. When the acceleration gear 62 rotates to drive the notched gear 63 to mesh with the full gear 64 again, the bottom end of the pull rope plate 66 is pulled upward again, thereby driving the cleaning frame 72 to move downward, and the outer surface of the lamp body 3 is lifted and wiped in a reciprocating cycle. When the inner cavity of the drying water collection bin 52 is completely filled with the quick-drying diatom drying strips, the drying water collection bin 52 is lowered to the bottom. At this time, rainwater will enter the inner cavity of the heat dissipation cavity plate 57 along the telescopic tube 55 and the diverter tube 56, and the heat dissipation cavity plate 57 will fit with the lamp body 3, so that the water flowing in the inner cavity of the heat dissipation cavity plate 57 absorbs heat and cools the lamp body 3, and then the rainwater is discharged through the drain pipe 58; After the rain stops, the quick-drying diatom drying strips dry quickly, so that the weight of all the quick-drying diatom drying strips is reduced to the initial state. After the spring component 1 51 loses pressure, it stretches and releases its elasticity, driving the dry water collection bin 52 to move upward and reset, and driving the water baffle 54 to reset upward, so that the air inlet tube 41 can resume communication with the inner cavity of the mounting shell 2.
