Description

Technical Field

[0001] The invention relates to an explosion-proof traffic signal lamp for use in a high temperature environment, and in particular to an explosion-proof traffic signal lamp for use in a high temperature environment that is applied in the technical field of traffic control. Background Art

[0002] Traffic lights are an indispensable and important equipment in modern traffic management. They play a vital role in ensuring traffic safety and improving traffic efficiency. However, in high-temperature, flammable and explosive industries such as petrochemicals, metallurgy, and coal, ordinary traffic lights are difficult to meet the stringent use requirements. Such environments are not only hot, but also full of flammable and explosive gases. Once the equipment is out of control, it is very easy to cause serious accidents, resulting in heavy casualties and property losses. Therefore, the development of an explosion-proof traffic light suitable for high-temperature, flammable and explosive environments is of great significance to improving the safety production level of related industries.

[0003] At present, there are some explosion-proof traffic lights designed for flammable and explosive environments on the market, but there are still some shortcomings. For example, Chinese invention patent CN113470399B discloses an explosion-proof traffic light, which uses a combustible gas sensor to sense flammable and explosive gases, and controls the drive device to drive the signal light box to flip into the placement slot to prevent explosion fragments from splashing. Although this design has achieved explosion-proof function to a certain extent, its structure is complex and does not consider the impact of high temperature environment on the equipment.

[0004] For another example, Chinese invention patent CN111798682B discloses a highly efficient heat dissipation and shock absorption ground-mounted traffic light, which improves the heat dissipation effect and stability through the heat dissipation unit and shock absorption design. However, it is aimed at general environments and lacks necessary explosion-proof measures, making it difficult to apply to flammable and explosive occasions.

[0005] In addition, most existing technologies have not fully considered the heat dissipation problem in high temperature environments. High temperature will not only accelerate the aging of equipment and shorten its service life, but may also cause circuit failures, and then induce explosion accidents. At the same time, the existing designs need to be further improved in terms of power supply safety, intelligent adjustment, and lightweight.

[0006] In response to the special needs of high-temperature flammable and explosive environments, the present invention aims to develop an explosion-proof traffic light with reliable explosion-proof performance, excellent heat dissipation effect, safe and stable power supply, flexible intelligent adjustment, strong self-repair ability, lightweight and environmentally friendly. The traffic light can be widely used in petrochemical, metallurgy, coal and other high-temperature flammable and explosive industries and traffic management in complex environments, effectively improving operational safety and traffic management level, promoting technological progress in related fields, and has good market application prospects and social benefits.

[0037] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 12 As shown, this embodiment provides an explosion-proof traffic light for high temperature environment, including a controller and an upper shell 1 and a lower shell 2 symmetrically arranged in the upper and lower parts, the top of the upper shell 1 is fixedly connected to a heat sink 3, the bottom end of the heat sink 3 is fixedly connected to a one-way heat conducting column 4, the bottom end of the one-way heat conducting column 4 is fixedly connected to an upper guide sleeve 5, the inner wall of the upper guide sleeve 5 is slidably connected to an upper sliding ring 6, the inner wall of the upper sliding ring 6 is fixedly connected to an upper adjusting column 7, the bottom end of the upper guide sleeve 5 is fixedly connected to an upper clamping block 8 and a lower clamping block 9 symmetrically arranged in the upper and lower parts, a lamp holder 10 is clamped between the upper clamping block 8 and the lower clamping block 9, and the bottom end of the upper adjusting column 7 is fixedly connected to the top of the lamp holder 10.

[0040] Four signal lights 11 are fixedly connected to the outer end of the lamp holder 10, and the signal lights 11 are electrically connected to the controller. An inner lens 12 is correspondingly arranged on the outer side of each signal light 11, and the multiple inner lenses 12 are clamped between the upper clamping block 8 and the lower clamping block 9. An isolation ring 13 is slidably connected to the end of each inner lens 12 away from the signal light 11, and an outer lens 14 is fixedly connected to the end of each isolation ring 13 away from the inner lens 12. The outer ends of the multiple outer lenses 14 are clamped between the upper shell 1 and the lower shell 2.

[0041] Furthermore, the upper shell 1 and the lower shell 2 are both hollow structures, and the hollow parts are filled with liquid foaming agent, the heat sink 3 and the one-way heat conducting column 4 are both made of pure copper and are hollow structures, the inner wall of the hollow part is fixedly connected to a porous foam metal layer, and the top of the heat sink 3 is fixedly connected to a heat dissipation fin, which is beneficial to enhance the heat dissipation effect.

[0042] In addition, the inner lens 12 and the outer lens 14 are both made of transparent flexible materials and are filled with silicone oil. The isolation ring 13 is made of flexible material and isolates the inner lens 12 and the outer lens 14 by one to three centimeters. This design allows the lens and the isolation ring 13 to buffer external impacts through deformation and protect the internal signal light 11.

[0043] The upper shell 1 and the lower shell 2 form the main structure of the explosion-proof traffic light, and the interior is filled with liquid foaming agent to play an explosion-proof role.

[0044] The heat sink 3 and the one-way heat conducting column 4 are made of pure copper with high thermal conductivity and are filled with porous foam metal to absorb and conduct the heat generated by the signal lamp 11 when it is working, achieving one-way heat dissipation. The heat dissipation fins on the top enhance the heat dissipation effect.

[0045] The upper guide sleeve 5, the upper sliding ring 6 and the upper adjusting column 7 form a retractable structure, which can buffer the impact force by sliding when impacted, thereby protecting the internal components.

[0046] The upper clamping block 8, the lower clamping block 9, the lamp holder 10 and the signal lamp 11 form a signal lamp module. The signal lamp 11 emits light to generate a traffic signal, which is controlled by a controller.

[0047] The inner lens 12, the isolation ring 13 and the outer lens 14 are made of transparent flexible materials and an isolation design, which can buffer external forces while guiding light and protect the signal light. The interior is filled with silicone oil, which can both guide light and further buffer impact force.

[0048] First, the explosion-proof traffic signal light is installed at a suitable position so that the connecting line of the upper shell 1 and the lower shell 2 is perpendicular to the horizontal plane.

[0049] The power supply coil 19 supplies power to the power receiving coil 17 by electromagnetic induction, and the power receiving coil 17 in turn supplies power to the four signal lamps 11 and the controller.

[0050] The controller adjusts the four signal lights 11 to light up or shut down according to traffic needs, and emits different traffic indicator lights. The light emitted by the signal lights 11 passes through the inner lens 12, the isolation ring 13, and the outer lens 14 in sequence and is emitted to the outside.

[0051] According to the requirements of environmental conditions, the controller can adjust the shape of the adjustment ring 21, change the focal length of the inner lens 12 or the outer lens 14, and optimize the emission state of the light of the signal light 11. For example, the light can be adjusted to be more concentrated on foggy days.

[0052] The explosion-proof traffic light provided in this embodiment can automatically fill the cracks when the shells rupture by filling liquid foaming agent in the upper shell 1 and the lower shell 2, thereby playing an explosion-proof role and being suitable for use in flammable and explosive high-temperature environments.

[0053] The heat sink 3, the one-way heat-conducting column 4 and the porous foam metal layer filled therein constitute a one-way heat-dissipating structure, which can effectively absorb and conduct the heat generated by the signal lamp 11 when it is working, protect the internal circuit components, and increase the service life.

[0054] The upper guide sleeve 5, the upper sliding ring 6 and the upper adjusting column 7 form a retractable structure, which can buffer the impact force by sliding when impacted, thereby improving the overall impact resistance.

[0055] The inner lens 12 and the outer lens 14 are made of transparent flexible material and are filled with silicone oil, which can both guide light and buffer external forces. At the same time, a flexible isolation ring 13 is provided to isolate the two layers of lenses. When impacted, the impact force can be further buffered by deformation, thereby providing good protection for the signal light 11.

[0056] By controlling the adjustment ring 21 to change the focal length of the lens, the light output state of the signal lamp 11 can be optimized to adapt to environments with different visibility and be less affected by environmental conditions.

[0057] Example 2

[0058] On the basis of Example 1, Figures 1 to 12 As shown, a lower adjusting column 15 is fixedly connected to the bottom end of the lamp holder 10, a lower sliding ring 16 is fixedly connected to the outer end of the lower adjusting column 15, a power receiving coil 17 is fixedly connected to the bottom end of the lower adjusting column 15, the power receiving coil 17 is electrically connected to the controller, a lower guide sleeve 18 is fixedly connected to the bottom end of the lower clamping block 9, the inner wall of the lower guide sleeve 18 is slidably connected to the outer end of the lower sliding ring 16, a power supply coil 19 is fixedly connected to the inner wall of the bottom end of the lower shell 2, the power supply coil 19 is electrically connected to an external power supply, and power can be supplied to the power receiving coil 17 by electromagnetic induction.

[0059] Furthermore, the heat sink 3 and the one-way heat conducting column 4 are filled with a cooling evaporative medium, the volume of which does not exceed one third of the filling space, and the upper adjustment column 7, the lamp holder 10, the lower adjustment column 15 and the power receiving coil 17 are provided with through holes connected to the interior of the upper guide sleeve 5 and the lower guide sleeve 18 in the vertical direction, and the through holes and the upper guide sleeve 5 and the lower guide sleeve 18 are filled with silicone oil to form a closed silicone oil heat dissipation circuit.

[0060] It is worth mentioning that the upper adjustment column 7 and the lower adjustment column 15 are both made of aluminum alloy with a hollow thin-wall structure, and the hollow part is filled with inert gas. This design can reduce the overall weight while ensuring sufficient strength.

[0061] The lower adjusting column 15, the lower sliding ring 16 and the lower guiding sleeve 18 form a similar retractable structure as the upper adjusting column 7, the upper sliding ring 6 and the upper guiding sleeve 5, which can slide and buffer when subjected to impact to protect the internal circuit components.

[0062] The power receiving coil 17 cooperates with the power supply coil 19 to realize wireless power supply, thereby avoiding the risk of electric sparks due to poor contact.

[0063] The cooling evaporation medium is filled in the heat sink 3 and the one-way heat conducting column 4, and can be condensed and refluxed after absorbing heat and evaporating, thus forming a phase change heat dissipation loop.

[0064] The vertical through hole and silicone oil form a closed loop between the upper and lower adjustment columns 7 and 15, the lamp holder 10, the power receiving coil 17, and the upper and lower guide sleeves 5 and 18. When the silicone oil is heated, it convects along the through hole to conduct heat away.

[0065] The upper adjustment column 7 and the lower adjustment column 15 are both made of aluminum alloy, and can be deformed to absorb impact when the internal pressure is too large.

[0066] When the signal lamp 11 is working, the silicone oil in the upper guide sleeve 5 and the lower guide sleeve 18 is heated, and the heated silicone oil flows upward through the through hole in the lamp holder 10, transferring the heat to the bottom end of the one-way heat conducting column 4, and the cooled silicone oil flows back to the bottom of the lower guide sleeve 18 through the convection tube 20, completing a heat dissipation cycle.

[0067] The cooling evaporative medium in the one-way heat-conducting column 4 absorbs the heat from the silicone oil circuit and then evaporates, taking away a large amount of heat and transferring it to the bottom of the heat sink 3. The condensed cooling evaporative medium flows back to the bottom of the one-way heat-conducting column 4 through the porous foam metal layer, completing the phase change heat dissipation cycle. The working process inside the heat sink 3 is similar to that of the one-way heat-conducting column 4. Finally, the heat is dissipated into the air through the heat sink fins.

[0068] The wireless power supply system composed of the power receiving coil 17 and the power supply coil 19 avoids the risk of electric sparks due to poor contact and improves safety in flammable and explosive environments.

[0069] The upper adjustment column 7 and the lower adjustment column 15 adopt a hollow thin-walled aluminum alloy structure, which is filled with inert gas, thereby reducing the overall weight while ensuring sufficient strength, and facilitating installation and adjustment.

[0070] The cooling evaporative medium filled in the heat sink 3 and the one-way heat conducting column 4 provides phase change heat dissipation, absorbs heat by evaporation, releases heat by condensation, and has high heat dissipation efficiency, which can effectively reduce the operating temperature of the signal lamp 11.

[0071] The vertical through holes and silicone oil form a closed loop between the upper adjustment column 7 and the lower adjustment column 15, the lamp holder 10, the power receiving coil 17, and the upper guide sleeve 5 and the lower guide sleeve 18. The heated silicone oil convectively circulates to take away the heat, complementing the phase change heat dissipation circuit and further enhancing the overall heat dissipation capacity.

[0072] The upper guide sleeve 5 and the lower guide sleeve 18 together with the upper sliding ring 6 and the lower sliding ring 16 form a retractable structure, which can buffer the impact force by sliding when subjected to external impact. Together with the flexible lens and the isolation ring 13 in Example 1, the internal circuit components are fully protected.

[0073] Example 3

[0074] On the basis of Examples 1 and 2, Figures 1 to 12As shown, a bottom cover is fixedly connected to the bottom end of the lower guide sleeve 18 to close the lower end of the silicone oil circuit, and a convection tube 20 is fixedly connected between the top end of the upper sliding ring 6 and the bottom end of the lower sliding ring 16 to connect the upper and lower parts of the silicone oil circuit.

[0075] An adjustment ring 21 is fixedly connected to the inner lens 12 and the outer lens 14. The adjustment ring 21 is electrically connected to the controller. The adjustment ring 21 includes a symmetrically arranged memory alloy ring and an electrostrictive material ring, which can be deformed when powered on to adjust the focal length of the lens.

[0076] A through hole is provided in the center of the isolation ring 13 so that the light emitted by the signal lamp 11 can pass through. Aerogel is filled between the upper guide sleeve 5 and the upper shell 1, and between the lower guide sleeve 18 and the lower shell 2, which can play a dual role of heat insulation and buffering.

[0077] The bottom cover closes the lower end of the silicone oil circuit to prevent silicone oil leakage.

[0078] The convection pipe 20 is connected to the upper sliding ring 6 and the lower sliding ring 16, so that the silicone oil circuits in the upper and lower guide sleeves 5 and 18 are connected to form a closed circulation loop.

[0079] The adjustment ring 21 is composed of a memory alloy ring and an electrostrictive material ring. When powered on, it deforms to drive the lens to change its focal length, thereby adjusting the degree of convergence of light.

[0080] The through hole in the center of the isolation ring 13 allows the light of the signal lamp 11 to pass through, and the isolation ring 13 can provide a restoring force when it is impacted.

[0081] The aerogel filler is filled between the upper guide sleeve 5 and the upper shell 1, and between the lower guide sleeve 18 and the lower shell 2, which can both insulate and buffer impact force.

[0082] When the entire device is subjected to external impact, the upper adjustment column 7, the upper clamping block 8, the lower clamping block 9, the lamp holder 10, the lower adjustment column 15, the lower sliding ring 16, the power receiving coil 17 and the signal light 11 can slide up and down in the upper guide sleeve 5 and the lower guide sleeve 18 to buffer the impact force. At the same time, the isolation ring 13 can provide a reset force to reset the device after the impact ends.

[0083] If the inner and outer lenses 12 and 14 or the adjustment ring 21 are deformed due to impact, the controller can energize the corresponding adjustment ring 21 to restore the memory alloy ring and the electrostrictive material ring to their original state under the action of the current, thereby driving the lens to recover. This self-healing ability can reduce the damage to the lens caused by impact to a certain extent.

[0084] The setting of the convection tube 20 connects the silicone oil circuits in the upper guide sleeve 5 and the lower guide sleeve 18 to form a closed loop. The silicone oil can circulate continuously inside to continuously conduct heat generated when the signal lamp 11 is working. The setting of the bottom cover prevents silicone oil leakage and ensures the integrity of the circuit.

[0085] The adjustment ring 21 utilizes the characteristics of memory alloy and electrostrictive material, and adjusts the focal length of the lens by powering on, so as to dynamically optimize the light output state of the signal light 11 according to the change of environmental visibility, thereby expanding the use scenarios and adaptability.

[0086] When the device is subjected to impact, the upper adjustment column 7, the lower adjustment column 15, the signal light 11 and other components can slide in the upper guide sleeve 5 and the lower guide sleeve 18 to buffer the impact, and the reset force provided by the isolation ring 13 can effectively protect the internal circuit components from damage.

[0087] The through hole in the center of the isolation ring 13 ensures the normal emission of light from the signal lamp 11. At the same time, the isolation ring 13 can be deformed to absorb impact force and reset after the impact is eliminated, thereby improving the impact resistance of the lens assembly.

[0088] Aerogel is filled between the upper guide sleeve 5 and the lower guide sleeve 18 and the upper shell 1 and the lower shell 2, and its excellent heat insulation performance is used to block the external high temperature. At the same time, this flexible porous material can also buffer the impact force and protect the interior of the device in all directions.

[0089] Once the inner lens 12 and the outer lens 14 or the adjustment ring 21 are deformed due to impact, the adjustment ring 21 can be restored to its original shape to a certain extent by being energized, thereby providing a self-repairing capability, extending the service life, and reducing maintenance costs.

[0090] When in use, the device is installed at a suitable position so that the line connecting the upper shell 1 and the lower shell 2 is perpendicular to the horizontal plane. The device can be installed on various platforms, equipment or the ground.

[0091] When in use, the power supply coil 19 supplies power to the power receiving coil 17 through induction, and the power receiving coil 17 supplies power to multiple signal lights 11 and a controller. The controller adjusts the multiple signal lights 11 to emit the required light signals as needed. The pipelines are emitted from the multiple signal lights 11 through the inner lens 12 and the outer lens 14 to the outside. The wireless power supply allows the signal lights 11 to maintain normal operation during movement and is not prone to sparks due to poor contact.

[0092] During use, the silicone oil in the upper guide sleeve 5 and the lower guide sleeve 18 is heated by multiple signal lamps 11, and the heated silicone oil flows upward through the through holes in the lamp holder 10 and transfers the heat to the bottom end of the one-way heat conducting column 4. The cooled silicone oil flows back to the bottom of the lower guide sleeve 18 through multiple convection tubes 20 to participate in the next cycle.

[0093] After being heated, the cooling evaporative medium in the one-way heat-conducting column 4 transfers the heat to the bottom of the heat sink 3 by evaporation. The condensed cooling evaporative medium flows back to the bottom of the one-way heat-conducting column 4 through the porous foam metal layer. The working process in the heat sink 3 is the same as that of the one-way heat-conducting column 4. Finally, the heat is dissipated into the air through the heat dissipation fins at the top of the heat sink 3. Through the two one-way heat transfers, the silicone oil in the upper guide sleeve 5 is kept at a lower temperature. Different cooling evaporative media can be selected according to the required temperature.

[0094] If the upper shell 1 and the lower shell 2 are broken by external impact during use, the liquid foaming agent filled inside will flow out from the cracks to seal the cracks. At the same time, the upper adjustment column 7, the upper clamping block 8, the lower clamping block 9, the lamp holder 10, the lower adjustment column 15, the lower sliding ring 16, the power receiving coil 17 and the multiple signal lights 11 slide up and down in the upper guide sleeve 5 and the upper clamping block 8 to buffer the impact. In this process, the isolation ring 13 provides a reset force.

[0095] Aerogel is filled between the lower guide sleeve 18 and the lower shell 2 to insulate heat transfer and cushion impacts through deformation.

[0096] If the inner lens 12, the outer lens 14 or the adjustment ring 21 is deformed by impact, and cannot be restored to its original state only by the elasticity of the inner lens 12, the outer lens 14 and the adjustment ring 21 themselves, the controller energizes the corresponding adjustment ring 21. After the adjustment ring 21 is energized, the adjustment ring 21 restores its original state under the action of the current. In this process, the adjustment ring 21 drives the corresponding inner lens 12 or the outer lens 14 to restore its original state. At the same time, the inner lens 12 and the outer lens 14 can buffer the impact to a certain extent by deformation.

[0097] During use, the focal length of the corresponding inner lens 12 or outer lens 14 can be adjusted by adjusting the deformation of the adjustment ring 21, thereby adjusting the emission state of the signal light 11. For example, in the case of heavy dust, the light of the signal light 11 can be concentrated into a beam so that the light can be emitted at a farther distance.

[0098] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
