Water collecting type water-cooled buried lamp

Abstract

This utility model discloses a water-cooled in-ground light with a water collection system, relating to the field of in-ground lights. It includes a lampshade and a light-emitting body installed inside it. Two sets of symmetrically distributed heat sinks are provided on the outer bottom of the lampshade, and a protective cover is provided at the bottom of the lampshade. The protective cover has a flanged structure extending upwards to the outer side of the lampshade. During normal use, the heat sinks dissipate heat from the lampshade and the light-emitting body inside, allowing heat to dissipate through the gap between the protective cover and the lampshade. In extremely hot weather, the cooling water inside the first and second water-cooling jackets can directly cool the outside of the lampshade, rapidly reducing its temperature. The cooling water inside the drainage pipe can also cool the outside of the two sets of heat sinks, accelerating heat dissipation from the outside of the lampshade and improving cooling efficiency.

Description

Technical Field

[0001] This utility model relates to the field of underground lights, and in particular to a water-cooled underground light with a water collection system. Background Technology

[0002] In-ground lights typically use die-cast aluminum or stainless steel for their bodies, making them sturdy, durable, waterproof, and with excellent heat dissipation. The cover is usually made of precision-cast stainless steel, which is corrosion-resistant and anti-aging. They also feature silicone sealing rings for excellent waterproofing, high-temperature resistance, and effective protection against underground moisture and rain. In-ground lights mostly use LED light sources, which are energy-efficient and bright, saving significant amounts of electricity compared to traditional incandescent bulbs. Furthermore, LED light sources have a long lifespan, generally exceeding 50,000 hours, virtually eliminating the need for bulb replacements and reducing the frequency of lamp replacements and maintenance costs. With the light body buried underground, only a small portion of the lamp head is exposed, saving space and maintaining a discreet appearance that doesn't disrupt the overall landscape.

[0003] Existing in-ground lights, due to their long-term underground burial, dissipate heat slowly during daily use. With prolonged use, the accumulated heat can cause internal components to overheat and wear, affecting the normal operation of the lights. In extreme heat weather, the probability of malfunction increases, disrupting normal lighting. Utility Model Content

[0004] To address the aforementioned issues, this application provides a water-cooled underground lamp with a water collection system.

[0005] To achieve the above objectives, this application provides the following technical solution: a water-cooled underground lamp with a water collection system, including a lampshade and a light-emitting lamp body installed inside it. The lampshade has two sets of heat sinks symmetrically distributed on the outer side of its bottom end, and a protective cover is provided at the bottom end of the lampshade. The protective cover has a flanged structure that extends upward to the outer side of the lampshade.

[0006] It also includes a pressure plate, at the bottom of which a first water-cooling jacket and a second water-cooling jacket are fixedly arranged symmetrically. The first water-cooling jacket and the second water-cooling jacket are connected by two sets of drainage pipes arranged from top to bottom. When the first water-cooling jacket and the second water-cooling jacket are installed inside the gap between the protective cover and the lamp cover, the first water-cooling jacket and the second water-cooling jacket are staggered with the two sets of heat sinks. The two sets of drainage pipes are located on the outside of the two sets of heat sinks respectively. Cooling water poured into the first water-cooling jacket or the second water-cooling jacket can flow in the drainage pipes and flow from the outside of the two sets of heat sinks to the inside of the second water-cooling jacket or the first water-cooling jacket.

[0007] Furthermore, the outer side of the lamp cover is connected to two symmetrically distributed rotating supports via two rotating shafts. A positioning sleeve is provided below the rotating support, and the positioning sleeve is connected to a swing pin via a pressure spring. The swing pin has an L-shaped structure. When the first water-cooling jacket and the second water-cooling jacket are installed inside the cover, the rotating support and the swing pin are located above the drainage pipe, and the rotating support is located directly below the pressure plate. The vertical rod of the swing pin passes through the rotating support and the pressure plate.

[0008] Furthermore, each swing pin has a paddle fixed to one end near the positioning sleeve. Pressing the paddle causes the swing pin to descend, and the vertical rod of the swing pin disengages from the rotating support and pressure plate.

[0009] Furthermore, each swing pin is fixed with a limiting rod near one end of the positioning sleeve. The limiting rod extends to the inside of the positioning sleeve and is coaxially distributed with the pressure spring. As the swing pin descends and the pressure spring stretches, the limiting rod moves downward inside the positioning sleeve.

[0010] Furthermore, two symmetrically distributed first channels are provided on the pressure plate. When the swing pin passes through the rotating support and the pressure plate, the swing pin and the rotating support are located directly below the first channel. Both the first water cooling jacket and the second water cooling jacket are provided with water inlets. The pressure plate is provided with second channels corresponding to the two water inlets.

[0011] Furthermore, the pressure plate is provided with guide rails arranged in a ring structure, and two first guard plates adapted to the first channel and two second guard plates adapted to the second channel are installed on the guide rails.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In normal use, the lampshade and its internal light-emitting body of this invention are cooled by heat sinks, allowing heat to dissipate through the gap between the cover and the lampshade. In extremely hot weather, the cooling water inside the first and second water-cooling jackets can be directly placed on the outside of the lampshade for cooling, enabling a rapid reduction in the lampshade's temperature. Meanwhile, the cooling water inside the drainage pipes can be placed on the outside of the two sets of heat sinks for cooling, accelerating the dissipation of heat from the outside of the lampshade and improving the efficiency of the cooling process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Reference Figure 1 , Figure 2 and Figure 5 The illustrated water-cooled in-ground light includes a lampshade 1 and a light-emitting body installed inside it. Two sets of symmetrically distributed heat sinks 2 are provided on the outer bottom of the lampshade 1, and a protective cover 3 is provided at the bottom of the lampshade 1. The protective cover 3 has a flanged structure extending upwards to the outer side of the lampshade 1. During normal use, the heat sinks 2 can dissipate heat from the lampshade 1 and its internal light-emitting body, allowing heat to dissipate through the gap between the protective cover 3 and the lampshade 1. This effectively prevents wear and tear on internal circuit components caused by heat accumulation on the outer surface of the lampshade 1, ensuring that the lampshade 1 and its internal light-emitting body maintain normal illumination brightness during long-term operation.

[0023] Furthermore, it also includes a pressure plate 4, with a first water-cooling jacket 5 and a second water-cooling jacket 6 symmetrically arranged at the bottom of the pressure plate 4. The first water-cooling jacket 5 and the second water-cooling jacket 6 are connected by two sets of drainage pipes 7 arranged from top to bottom. When the first water-cooling jacket 5 and the second water-cooling jacket 6 are installed inside the gap between the protective cover 3 and the lamp cover 1, the pressure plate 4 is located at the top of the gap space formed by the protective cover 3 and the lamp cover 1. The first water-cooling jacket 5 and the second water-cooling jacket 6 are staggered with the two sets of heat sinks 2, and the two sets of drainage pipes 7 are located on the outside of the two sets of heat sinks 2 respectively. In case of extreme hot weather, coolant can be poured into the inside of the first water-cooling jacket 5 or the second water-cooling jacket 6. The coolant poured into the first water-cooling jacket 5 or the second water-cooling jacket 6 can flow in the drain pipe 7 and flow from the outside of the two sets of heat sinks 2 to the inside of the second water-cooling jacket 6 or the first water-cooling jacket 5 until the first water-cooling jacket 5 and the second water-cooling jacket 6 are full of coolant. At this time, the inside of the two sets of drain pipes 7 is also full of coolant.

[0024] The cooling water inside the first water-cooling jacket 5 and the second water-cooling jacket 6 can be directly applied to the outside of the lamp cover 1 for cooling, allowing the temperature of the lamp cover 1 to drop rapidly in hot weather. Meanwhile, the cooling water inside the drain pipe 7 can be applied to the outside of the two sets of heat sinks 2 for cooling, accelerating the dissipation of heat from the outside of the lamp cover 1. In a relatively short time, the lamp cover 1 and its internal light-emitting body can be comprehensively cooled, further improving the efficiency of the cooling process.

[0025] like Figure 3 , Figure 4 As shown, two symmetrically distributed rotating supports 9 are connected to the outside of the lamp cover 1 via two rotating shafts. A positioning sleeve 10 is provided below the rotating support 9. The positioning sleeve 10 is connected to a swing pin 11 via a pressure spring 12. The swing pin 11 has an L-shaped structure. When the first water cooling sleeve 5 and the second water cooling sleeve 6 are installed inside the cover 3, the rotating support 9 and the swing pin 11 are rotated out. Both of them are located above the drain pipe 7, and the rotating support 9 is located directly below the pressure plate 4. The vertical rod of the swing pin 11 passes through the rotating support 9 and the pressure plate 4, locking the rotating support 9 and the pressure plate 4 together.

[0026] Since the rotating support 9 and the swing pin 11 are both located above the drainage pipe 7, the pressure plate 4 cannot move vertically when the swing pin 11 locks the rotating support 9 and the pressure plate 4, and the pressure plate 4 cannot rotate. This maintains the stability of the pressure plate 4 and the safety of the first water cooling jacket 5, the second water cooling jacket 6 and the drainage pipe 7.

[0027] like Figure 4As shown, a lever 14 is fixed to one end of the swing pin 11 near the positioning sleeve 10. If it is necessary to disassemble the pressure plate 4 to replace the coolant inside the first water-cooling jacket 5 and the second water-cooling jacket 6, the lever 14 can be pressed to lower the swing pin 11, stretching the pressure spring 12. Subsequently, rotating the rotating support 9 and the swing pin 11 causes the vertical rod of the swing pin 11 to disengage from the rotating support 9 and the pressure plate 4, and both the rotating support 9 and the swing pin 11 move away from the top of the drain pipe 7, leaving space for the drain pipe 7 to move upward. Finally, the pressure plate 4 can be controlled to raise the first water-cooling jacket 5, the second water-cooling jacket 6, and the drain pipe 7 together, allowing for the replacement of the coolant inside the first water-cooling jacket 5 and the second water-cooling jacket 6. During this process, it is not necessary to disassemble the entire lamp cover 1 and the light-emitting lamp body, improving the portability of the operation.

[0028] like Figure 4 As shown, each swing pin 11 near the positioning sleeve 10 is fixed with a limiting rod 13. The limiting rod 13 extends into the inner side of the positioning sleeve 10 and is coaxially distributed with the pressure spring 12. As the swing pin 11 descends and the pressure spring 12 stretches, the limiting rod 13 moves downward inside the positioning sleeve 10. The limiting rod 13 prevents the swing pin 11 from deviating during its vertical movement, ensuring the accuracy of operation during the adjustment of the swing pin 11.

[0029] Example 2: To facilitate smooth adjustment of the swing pin 11 and the rotating support 9 by the operator, two symmetrically distributed first channels 41 are provided on the pressure plate 4. When the swing pin 11 passes through the rotating support 9 and the pressure plate 4, the swing pin 11 and the rotating support 9 are located directly below the first channel 41. During operation, the operator can pass through the first channel 41 to smoothly adjust the swing pin 11 and the rotating support 9. To facilitate the addition of water to the first water-cooling jacket 5 and the second water-cooling jacket 6, both the first water-cooling jacket 5 and the second water-cooling jacket 6 are provided with water inlets 8. The pressure plate 4 is provided with second channels 42 corresponding to the two water inlets 8. During operation, the operator can pass through the second channel 42 to smoothly add water to one of the two water inlets 8.

[0030] like Figure 1 As shown, the pressure plate 4 is provided with a ring-shaped guide rail 43. Two first protective plates 44 adapted to the first channel 41 and two second protective plates 45 adapted to the second channel 42 are installed on the guide rail 43. During normal use of the lamp cover 1 and the light-emitting body inside, the two first protective plates 44 and the two second protective plates 45 respectively block the first channel 41 and the second channel 42 to prevent garbage and impurities from the external environment from entering below the pressure plate 4.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
