Description

Technical Field

[0001] This invention relates to the field of street light technology, specifically to an explosion-proof intelligent street light. Background Technology

[0002] Streetlights are lighting facilities installed in public places such as roads and squares, mainly used to provide artificial light sources at night or in low light conditions. High temperature is an important factor that can cause streetlights to explode. High temperature accelerates the aging and damage of the insulation layer of wires, causing short circuits in exposed cables to generate electric sparks. The continuous discharge of the sparks ignites flammable materials, and the heat accumulated in the confined space triggers an explosion.

[0003] A search revealed a Chinese patent with publication number CN115962455B, which discloses an explosion-proof LED street light, including a lamp holder, a liquid storage chamber, a mounting plate, a heat dissipation chamber, and a lamp body. The liquid storage chamber and the mounting plate are sequentially connected to the bottom of the lamp holder. The heat dissipation chamber is located in the middle of the bottom end of the mounting plate, and the lamp body is connected to the bottom of the heat dissipation chamber. The bottom diameter of the mounting plate is larger than the outer diameter of the heat dissipation chamber. An explosion-proof component is also provided at the bottom of the mounting plate. The explosion-proof component is located outside the heat dissipation chamber and the lamp body. Coolant is provided in the liquid storage chamber. A temperature sensing component is provided at the top of the lamp body. The temperature sensing component controls the connection between the liquid storage chamber and the heat dissipation chamber through temperature changes, resulting in better explosion-proof heat dissipation.

[0004] In the aforementioned technology, when the streetlight experiences high temperatures, the thermal expansion material expands, causing the sealing plate to move. This allows the coolant in the storage chamber to flow smoothly into the heat dissipation chamber, thereby cooling the lamp body. However, the heat dissipation chamber is located at the top of the lamp body, which is installed inside an explosion-proof enclosure. As a result, during heat dissipation, only the air near the heat dissipation chamber inside the explosion-proof enclosure is effectively cooled. Furthermore, the air inside the explosion-proof enclosure cannot circulate, making it difficult to cool the air temperature in areas far from the heat dissipation chamber. This affects the heat dissipation of the lamp body and makes it prone to high-temperature explosions. Summary of the Invention

A first one-way valve is installed at one end of the water inlet pipe, and a second one-way valve is installed at one end of the drain pipe.

[0008] Preferably, a first rotating shaft is rotatably connected to one end of the inner wall of the cooling cylinder, the bottom of the first rotating shaft extends into the interior of the air intake pipe and is rotatably connected to the air intake pipe, a fan is fixedly connected to the bottom of the first rotating shaft, and a first bevel gear is fixedly connected to the first rotating shaft above the air intake pipe.

[0009] Preferably, a second rotating shaft is rotatably connected to one end of the drain pipe, a turbine is fixedly connected to one end of the second rotating shaft, and a second bevel gear is fixedly connected to the other end of the second rotating shaft. The second bevel gear meshes with the first bevel gear.

[0010] Preferably, a stirring shaft is rotatably connected to the top center of the cooling cylinder, and multiple stirring blades are fixedly connected to both ends of the stirring shaft. A sleeve is rotatably connected to the stirring shaft above the stirring blades, and synchronous pulleys are fixedly connected to the middle of the sleeve and the top of the first rotating shaft. The two synchronous pulleys are driven by a synchronous belt.

[0011] Preferably, a mounting cover is fixedly connected to the bottom of the sleeve, and a spiral spring is fixedly connected to the inner wall of the mounting cover, with one end of the spiral spring fixedly connected to the stirring shaft.

[0012] Preferably, a first ratchet is fixedly connected to the top of the sleeve, and a first ratchet tooth is engaged at one end of the first ratchet. A first spring telescopic rod is fixedly connected to the top of the cooling cylinder at one end of the first ratchet tooth, and the first spring telescopic rod is fixedly connected to the first ratchet tooth.

[0013] Preferably, a second ratchet is fixedly connected to the stirring shaft above the sleeve, one end of the second ratchet is engaged with a second ratchet tooth, and a second spring telescopic rod is fixedly connected to the top of the cooling cylinder at one end of the second ratchet tooth, and the second spring telescopic rod is fixedly connected to the second ratchet tooth.

[0014] Preferably, a liquid storage cylinder is fixedly connected to the middle of the lamp post, the bottom of the liquid storage cylinder is connected to the water inlet pipe, a water tank is fixedly connected to the bottom of the lamp post, the bottom of the drain pipe is connected to the water tank, a water supply pipe is connected to the bottom of the side wall of the water tank, the top of the water supply pipe is connected to the bottom of the side wall of the liquid storage cylinder, and a third one-way valve is installed on the top of the water supply pipe.

[0015] Preferably, a cylinder is fixedly connected to the lamp post above the liquid storage cylinder, the output shaft of the cylinder extends into the inside of the liquid storage cylinder, and a moving block is fixedly connected thereto, the moving block being slidably connected to the liquid storage cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention accelerates the cooling rate of the lamp body through the design of a cooling mechanism, thereby preventing the lamp body from exploding due to excessive temperature. Coolant is supplied to the cooling cylinder, where the existing coolant flows back into the water tank through a drain pipe. As the coolant flows from the cooling cylinder into the drain pipe, it drives the turbine, the second shaft, and the second bevel gear to rotate, which in turn drives the first bevel gear, the first shaft, and the fan to rotate. During the rotation of the fan, the high-temperature air inside the explosion-proof lamp cover is drawn into the air intake pipe and flows into the cooling pipe. As this high-temperature air flows through the cooling pipe, its own heat is absorbed by the coolant, thus cooling the air inside the explosion-proof lamp cover. This cooled air then flows back into the explosion-proof lamp cover through the exhaust pipe, further reducing the heat inside the lamp cover. Simultaneously, this cooled air can absorb the heat generated by the lamp body, thereby improving the lamp body's heat dissipation effect. This invention utilizes a synchronous pulley and synchronous belt design to allow the sleeve to rotate synchronously with the first rotating shaft. As the sleeve rotates, it drives the mounting cover and the first ratchet to rotate. During this process, the spiral spring gradually contracts. When the supply of coolant to the cooling cylinder stops, the turbine, the second rotating shaft, and the second bevel gear stop rotating. When the second bevel gear stops rotating, the first bevel gear, the first rotating shaft, the synchronous pulley, the synchronous belt, the sleeve, and the first ratchet also stop rotating. When the mounting cover stops rotating, the spiral spring gradually rebounds. This rebound of the spiral spring drives the stirring shaft, which in turn drives the stirring blades to rotate, thereby stirring the coolant in the cooling cylinder and increasing its fluidity to ensure effective heat exchange. This invention uses a cylinder to drive a moving block to move up and down. When the moving block moves upward, the coolant in the water tank flows into the storage cylinder through the water supply pipe under negative pressure. When the moving block moves downward, the coolant in the storage cylinder flows into the cooling cylinder through the water inlet pipe, thereby absorbing the heat from the high-temperature air in the cooling cylinder. Meanwhile, the coolant that was already at a higher temperature in the cooling cylinder flows back into the water tank through the drain pipe. By intermittently supplying coolant to the cooling cylinder, the coolant that was at a higher temperature can have enough time to cool down when it flows back into the water tank, so that the coolant can have a better cooling effect in subsequent use.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1-9 This invention provides a technical solution: an explosion-proof intelligent street light, including a light pole 1, a cooling mechanism 2, and a lamp body 3. The cooling mechanism 2 is disposed at the top of the light pole 1 and includes a cooling cylinder 201, a cooling pipe 203, and an explosion-proof lamp cover 202. The cooling cylinder 201 is fixedly connected to the top of the light pole 1, and the explosion-proof lamp cover 202 is fixedly connected to the bottom of the cooling cylinder 201. The cooling pipe 203 is disposed inside the cooling cylinder 201 and is arranged in a ring-shaped wave pattern. The input end of the cooling pipe 203 is connected to an air inlet pipe 204, and the output end of the cooling pipe 203 is connected to an air outlet pipe 204. The exhaust pipe 205, the air inlet pipe 204, and the exhaust pipe 205 are all fixedly connected to the cooling cylinder 201 and communicate with the explosion-proof lamp cover 202. The bottom of the cooling cylinder 201 is fixedly connected to the reflector 206 around the explosion-proof lamp cover 202. The lamp body 3 is fixedly connected to the bottom of the cooling cylinder 201 and is located inside the explosion-proof lamp cover 202. One end of the side wall of the cooling cylinder 201 is connected to the water inlet pipe 207, and the other end of the side wall of the cooling cylinder 201 is connected to the drain pipe 208. One end of the water inlet pipe 207 is equipped with a first one-way valve 209, and one end of the drain pipe 208 is equipped with a second one-way valve 210. Specifically, after prolonged use, the lamp body 3 generates a large amount of heat. To prevent the lamp body 3 from exploding due to high temperatures, it needs to be cooled down. This requires supplying coolant to the inlet pipe 207, which then flows into the cooling cylinder 201. During this process, the high-temperature air inside the explosion-proof lamp cover 202 is drawn into the air inlet pipe 204 and flows into the cooling pipe 203. As this high-temperature air flows through the cooling pipe 203, its own heat is absorbed by the coolant, thus cooling the air inside the explosion-proof lamp cover 202. This cooled air then flows back into the explosion-proof lamp cover 202 through the exhaust pipe 205, further reducing the heat inside the explosion-proof lamp cover 202. Simultaneously, this cooled air absorbs the heat generated by the lamp body 3, improving its heat dissipation effect. Additionally, the cooling cylinder 201 absorbs... The high-temperature air heats up the coolant itself, and this higher-temperature coolant is discharged through the drain pipe 208 so that the lower-temperature coolant can flow smoothly into the cooling cylinder 201, thus ensuring the subsequent cooling effect. The design of the first one-way valve 209 ensures that the coolant can only flow from the inlet pipe 207 towards the cooling cylinder 201, and the design of the second one-way valve 210 ensures that the coolant can only flow from the cooling cylinder 201 towards the drain pipe 208. In addition, the explosion-proof lamp cover 202 is made of a light-transmitting material so that the light generated by the lamp body 3 can smoothly illuminate the outside of the explosion-proof lamp cover 202. Furthermore, by setting the cooling pipe 203 to a ring-shaped wave, the contact area between the cooling pipe 203 and the coolant is increased, and the travel distance of the high-temperature air in the cooling pipe 203 is increased, thereby ensuring the cooling effect of the coolant on the high-temperature air.

[0021] like Figure 3 , Figure 4 and Figure 6 As shown, a first rotating shaft 211 is rotatably connected to one end of the inner wall of the cooling cylinder 201. The bottom of the first rotating shaft 211 extends into the interior of the air intake pipe 204 and is rotatably connected to the air intake pipe 204. A fan wheel 212 is fixedly connected to the bottom of the first rotating shaft 211. A first bevel gear 213 is fixedly connected to the first rotating shaft 211 above the air intake pipe 204. A second rotating shaft 214 is rotatably connected to one end of the interior of the drain pipe 208. A turbine 215 is fixedly connected to one end of the second rotating shaft 214. A second bevel gear 216 is fixedly connected to the other end of the second rotating shaft 214. The second bevel gear 216 meshes with the first bevel gear 213. Specifically, as the coolant flows from the cooling cylinder 201 into the drain pipe 208, it drives the turbine 215 to rotate, which in turn drives the second shaft 214 and the second bevel gear 216 to rotate, which in turn drives the first bevel gear 213, the first shaft 211 and the impeller 212 to rotate. During the rotation of the impeller 212, the high-temperature air inside the explosion-proof lamp cover 202 can be drawn into the air intake pipe 204, so that the high-temperature air can flow smoothly into the cooling pipe 203 for cooling.

[0022] like Figures 4 to 8 As shown, a stirring shaft 217 is rotatably connected to the top center of the cooling cylinder 201. Multiple stirring blades 218 are fixedly connected to both ends of the stirring shaft 217. A sleeve 219 is rotatably connected above the stirring blades 218. Synchronous pulleys 220 are fixedly connected to the middle of the sleeve 219 and the top of the first rotating shaft 211. The two synchronous pulleys 220 are driven by a synchronous belt 221. A mounting cover 222 is fixedly connected to the bottom of the sleeve 219. A spiral spring 223 is fixedly connected to the inner wall of the mounting cover 222. One end of the spiral spring 223 is fixedly connected to the stirring shaft 217. A sleeve 219 is fixedly connected to the top. A first ratchet 224 is provided, with a first ratchet tooth 225 engaged at one end of the first ratchet 224. A first spring telescopic rod 226 is fixedly connected to the top of the cooling cylinder 201 at one end of the first ratchet tooth 225. The first spring telescopic rod 226 is fixedly connected to the first ratchet tooth 225. A second ratchet 227 is fixedly connected to the stirring shaft 217 above the sleeve 219. A second ratchet tooth 228 is engaged at one end of the second ratchet tooth 227. A second spring telescopic rod 229 is fixedly connected to the top of the cooling cylinder 201 at one end of the second ratchet tooth 228. The second spring telescopic rod 229 is fixedly connected to the second ratchet tooth 228. Specifically, since the coolant's own heat does not immediately increase during the absorption of heat from the high-temperature air, coolant can be intermittently supplied to the cooling cylinder 201 during actual operation. This allows the hot coolant discharged from the cooling cylinder 201 sufficient time to cool down for subsequent use. When coolant flows into the cooling cylinder 201 from the inlet pipe 207, the existing coolant in the cooling cylinder 201 flows into the drain pipe 208. The flow of coolant in the drain pipe 208 drives the turbine 215 to rotate, which in turn drives the second shaft 214 and the second bevel gear 216 to rotate, thereby driving... The first bevel gear 213 and the first rotating shaft 211 rotate. When the first rotating shaft 211 rotates, it drives the synchronous pulley 220 and the synchronous belt 221 to rotate, which in turn drives the sleeve 219 to rotate. When the sleeve 219 rotates, it drives the mounting cover 222 and the first ratchet 224 to rotate. Because the second ratchet 227 cannot rotate due to the limiting action of the second ratchet 228 (the second ratchet 227 is fixedly connected to the stirring shaft 217), the stirring shaft 217 also cannot rotate. Therefore, during the rotation of the mounting cover 222, the spiral spring 223 gradually contracts. When the supply of coolant to the cooling cylinder 201 stops, the spiral spring 223... When wheel 215, second shaft 214, and second bevel gear 216 stop rotating, the first bevel gear 213, first shaft 211, synchronous pulley 220, synchronous belt 221, and sleeve 219 also stop rotating. At this time, the first ratchet 224 and mounting cover 222 also stop rotating. When mounting cover 222 stops rotating, the spiral spring 223 gradually rebounds. Since the first ratchet 224 is limited to unidirectional rotation by the first ratchet tooth 225, the direction of the rotational force generated when the spiral spring 223 rebounds is blocked by the first ratchet tooth 225. Therefore, the spiral spring 223 rebounds... When the first ratchet 224 is released, it will not rotate, thus keeping the sleeve 219 stationary. The direction of the rotational force generated when the spiral spring 223 rebounds will not be blocked by the second ratchet 228. Therefore, when the spiral spring 223 rebounds, it will drive the stirring shaft 217, which in turn will drive the stirring blade 218 to rotate, thereby stirring the coolant in the cooling cylinder 201, increasing the fluidity of the coolant, and thus ensuring the heat exchange effect. It should be noted that the first ratchet 224 can only rotate clockwise under the limiting action of the first ratchet 225, and the second ratchet 227 can only rotate counterclockwise under the limiting action of the second ratchet 228.

[0023] like Figure 1 and Figure 9As shown, a liquid storage cylinder 4 is fixedly connected to the middle of the lamp post 1. The bottom of the liquid storage cylinder 4 is connected to the water inlet pipe 207. A water tank 5 is fixedly connected to the bottom of the lamp post 1. The bottom of the drain pipe 208 is connected to the water tank 5. A water supply pipe 6 is connected to the bottom of the side wall of the water tank 5. The top of the water supply pipe 6 is connected to the bottom of the side wall of the liquid storage cylinder 4. A third one-way valve 7 is installed on the top of the water supply pipe 6. A cylinder 8 is fixedly connected to the lamp post 1 above the liquid storage cylinder 4. The output shaft of the cylinder 8 extends into the inside of the liquid storage cylinder 4 and is fixedly connected to a moving block 9. The moving block 9 is slidably connected to the liquid storage cylinder 4. Specifically, before cooling the lamp body 3, coolant needs to be pre-filled into the water tank 5. When coolant needs to be supplied to the cooling cylinder 201, the moving block 9 can be moved up and down by the cylinder 8. When the moving block 9 moves upward, the coolant in the water tank 5 will flow into the storage cylinder 4 through the water pipe 6 under negative pressure. The design of the third one-way valve 7 ensures that the coolant can only flow from the water tank 5 to the storage cylinder 4. When the moving block 9 moves downward, the coolant in the storage cylinder 4 will flow into the cooling cylinder 201 through the water inlet pipe 207. The coolant absorbs the heat from the high-temperature air inside the cooling pipe 203, and the coolant that was originally in the cooling cylinder 201 at a higher temperature will flow back into the water tank 5 through the drain pipe 208. In order to ensure that the coolant in the water tank 5 has a good cooling effect, heat sinks or cooling rods can be installed in the water tank 5 during actual use. In addition, in order to ensure that the lamp body 3 can be cooled down in time, a temperature sensor can be installed at the bottom of the cooling cylinder 201 to monitor the temperature of the lamp body 3 in real time, and the controller receives the temperature information from the temperature sensor in order to control the opening and closing of the cylinder 8.

[0024] Working principle: After prolonged use, the lamp body 3 generates a large amount of heat. To prevent the lamp body 3 from exploding due to high temperature, it needs to be cooled down. This is achieved by the cylinder 8 driving the moving block 9 to move up and down. When the moving block 9 moves upward, the coolant in the water tank 5 flows into the reservoir 4 through the water pipe 6 under negative pressure. When the moving block 9 moves downward, the coolant in the reservoir 4 flows into the cooling cylinder 201 through the water inlet pipe 207. The existing coolant in the cooling cylinder 201 then flows back into the water tank 5 through the drain pipe 208. As the coolant flows from the cooling cylinder 201 into the drain pipe 208, it drives the turbine 215 to rotate, thereby driving the second... The rotating shaft 214 and the second bevel gear 216 rotate, which in turn drives the first bevel gear 213, the first rotating shaft 211 and the impeller 212 to rotate. During the rotation of the impeller 212, the high-temperature air inside the explosion-proof lamp cover 202 is drawn into the air intake pipe 204 and flows into the cooling pipe 203. When this high-temperature air flows in the cooling pipe 203, its own heat is absorbed by the coolant, thereby cooling the air inside the explosion-proof lamp cover 202. This cooled air will flow back into the explosion-proof lamp cover 202 through the exhaust pipe 205, thereby reducing the heat inside the explosion-proof lamp cover 202. At the same time, this cooled air can absorb the heat generated by the lamp body 3, thereby improving the heat dissipation effect of the lamp body 3. Additionally, when the first rotating shaft 211 rotates, it drives the synchronous pulley 220 and synchronous belt 221 to rotate, which in turn drives the sleeve 219 to rotate. The rotation of the sleeve 219 drives the mounting cover 222 and the first ratchet 224 to rotate. Because the second ratchet 227 cannot rotate due to the limiting action of the second ratchet 228 (the second ratchet 227 is fixedly connected to the stirring shaft 217), the stirring shaft 217 also cannot rotate. Therefore, during the rotation of the mounting cover 222, the spiral spring 223 gradually contracts. When the coolant supply to the cooling cylinder 201 stops, the turbine 215, the second rotating shaft 214, and the second bevel gear 216 will stop rotating. When the second bevel gear 216 stops rotating, the first bevel gear 213, the first rotating shaft 211, the synchronous pulley 220, the synchronous belt 221, and the sleeve 219 will all stop rotating. When the sleeve 219 stops rotating, the first ratchet 224 and the mounting cover 222 will also stop rotating. When the mounting cover 222 stops rotating, the scroll spring 223 will gradually rebound. Since the first ratchet 224 is limited by the first ratchet 225 and can only rotate in one direction, the direction of the rotational force generated when the scroll spring 223 rebounds is blocked by the first ratchet 225. Therefore, the first ratchet 224 will not rotate when the scroll spring 223 rebounds, thus keeping the sleeve 219 stationary. The direction of the rotational force generated when the scroll spring 223 rebounds will not be blocked by the second ratchet 228. Therefore, when the scroll spring 223 rebounds, it will drive the stirring shaft 217, which in turn drives the stirring blade 218 to rotate, thereby stirring the coolant in the cooling cylinder 201, thereby increasing the fluidity of the coolant and ensuring the heat exchange effect.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
