Description

Technical Field

[0001] The invention relates to the field of heat dissipation of street lamps, and in particular to a rainwater heat dissipation type buried street lamp used in hot and humid areas. Background Art

[0002] Underground street lights are lamps buried in the road surface. They have the advantage of not taking up space on the road surface and are often used in parks and some entertainment venues.

[0003] However, for some hot and humid areas with a lot of rain, in order to prevent rain from entering the underground lamp, the underground lamp adopts a relatively sealed structure as a whole. However, due to its sealed state, heat dissipation cannot be guaranteed. If it is in a hot working state for a long time, the service life of the lamp body will be greatly reduced. For this reason, we need to design a rainwater heat dissipation type underground street lamp for hot and humid areas to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a rainwater heat dissipation type underground street lamp for use in hot and humid areas. The underground street lamp uses rainwater to dissipate heat inside the lamp body, thereby ensuring the working temperature of the underground lamp. After the rainwater has been used for a period of time, it can be discharged to the outside and low-temperature rainwater can be introduced, so that the underground lamp is always at a more suitable working temperature.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] As an embodiment of the present invention, a heat dissipation mechanism is provided inside the shell 1, and the heat dissipation mechanism includes a spiral tube 4 embedded in the temperature conducting block 3, the spiral tube 4 is made of a temperature conducting material, the upper end portion of the spiral tube 4 is connected with a connecting pipe 20, the upper end of the connecting pipe 20 is connected with a liquid collecting bucket 18, the upper end surface of the liquid collecting bucket 18 is connected with the outside, the upper end surface of the liquid collecting bucket 18 is flush with the upper end surface of the shell 1, and the inside of the liquid collecting bucket 18 is filled with a filter layer 19, and the filter layer 19 can be a filter screen to prevent some larger impurities from clogging the connecting channel 20;

[0026] As an embodiment of the present invention, a liquid storage box 5 and a trigger box 23 are fixedly connected to the lower end of the shell 1, and a first temperature control component is arranged in the trigger box 23. The first temperature control component includes a first piston 6 slidably connected in the trigger box 23. The space on the right side of the trigger box 23 located on the first piston 6 is filled with a volatile liquid. The volatile liquid is chloroform, and its boiling point is 61°C. The trigger box 23 is made of an opaque material to prevent the chloroform from decomposing under light. A temperature conducting plate 7 is embedded in the top space of the trigger box 23 and the bottom space of the shell 1. The left part of the space of the trigger box 23 is connected to the right part of the space of the liquid storage box 5 through a one-way exhaust pipe 9, and the left part of the space of the trigger box 23 is connected to the outside through a one-way air intake pipe 8.

[0027] As an embodiment of the present invention, a liquid replacement mechanism for cooperating with the heat dissipation mechanism is provided in the liquid storage box 5, and the liquid replacement mechanism includes a second piston 10 slidably connected in the liquid storage box 5, and the left side of the second piston 10 is elastically connected to the left inner wall of the liquid storage box 5 through a force storage spring 11, and the left space of the liquid storage box 5 is connected to the outside through a one-way liquid outlet pipe 12, and the left space of the liquid storage box 5 is connected to the lower end of the spiral tube 4 through a one-way liquid inlet pipe 13, and one-way valves are installed in the one-way air inlet pipe 8, the one-way exhaust pipe 9, the one-way liquid inlet pipe 13 and the one-way liquid outlet pipe 12, and the setting of the one-way valve ensures the one-way fluidity of the gas;

[0028] As an embodiment of the present invention, it also includes a second temperature control component, which includes an adjustment box 14 installed at the bottom of the shell 1. The adjustment box 14 is also made of heat-conducting material. The right side space of the liquid storage box 5 is connected to the outside through a connecting pipe 17. The adjustment box 14 runs through the connecting pipe 17. An adjustment slider 15 for sliding left and right is provided in the adjustment box 14. A dredging port 21 that cooperates with the connecting pipe 17 is vertically penetrated on the adjustment slider 15. The left side of the adjustment slider 15 is connected to the left inner wall of the adjustment box 14 through a memory wire 16. The memory wire 16 is a two-way memory type. It is strip-shaped in a low temperature state and spirally downward in a high temperature state. Its transformation temperature is 75°C. Two limit rings 22 are symmetrically installed in the adjustment box 14.

[0029] In the present invention, after the lamp body 2 is started on a rainy day, due to the initial state, rainwater will enter the connecting pipe 20, the spiral tube 4, the one-way liquid inlet pipe 13 and the liquid storage box 5 from the liquid collecting bucket 18, and the heat generated by the lamp body 2 here will be absorbed by the temperature conducting block 3, and transferred to the low-temperature water body in the spiral tube 4, the connecting pipe 20 and the one-way liquid inlet pipe 13, and heat transfer type heat dissipation will be performed. When the low-temperature water body continuously absorbs heat, the temperature will slowly rise. When the low-temperature water body cannot meet the heat dissipation effect, the temperature inside the entire housing 1 will rise at this time;

[0030] When the temperature inside the housing 1 reaches above 61°C, the temperature is transferred to the evaporative liquid through the heat conducting plate 7, causing the evaporative liquid to evaporate, pushing the first piston 6 to move leftward. After the first piston 6 moves leftward, the gas in the left space of the trigger box 23 is pressed into the right space of the liquid storage box 5 through the one-way exhaust pipe 9. At this time, the connecting pipe 17 is blocked by the adjusting slider 15, so the gas in the right space of the liquid storage box 5 increases, causing the second piston 10 to move leftward, and press the water in the left space of the liquid storage box 5 to the outside through the one-way liquid outlet pipe 12.

[0031] Until reaching Figure 5The evaporative liquid evaporates completely. As the temperature inside the shell 1 continues to rise and reaches above 75°C, the memory wire 16 becomes spiral and pulls the adjusting slider 15 to move left to clear the connecting pipe 17. After the connecting pipe 17 is cleared, the second piston 10 acts quickly under the elastic effect of the storage spring 11 and completely draws the rainwater in the connecting pipe 20, the spiral tube 4 and the one-way liquid inlet pipe 13 into the left space of the liquid storage box 5. At this time, the rainwater from the outside will fill the connecting pipe 20, the spiral tube 4 and the one-way liquid inlet pipe 13 along the liquid collecting bucket 18 again. The low-temperature rainwater will quickly cool down the inside of the shell 1 (lamp body 2). Through the thermal conductivity of the thermal conductive plate 7 and the regulating box 14 itself, the evaporative liquid and the memory wire 16 will return to their original state. Figure 1 State, when the temperature of the rainwater inside the housing 1 rises again, the above process will be repeated;

[0032] By providing the memory metal wire 16 and the evaporative liquid, rainwater can be discharged to the outside after being used for a period of time, and low-temperature rainwater can be introduced again, so that the underground lamp is always at a more suitable working temperature.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
