Abstract
Description
Technical Field
[0001] The present invention relates to the field of lighting technology, and in particular to an energy-saving smart street lamp. Background Art
[0002] With the continuous advancement of urbanization and people's pursuit of energy conservation, environmental protection and intelligent life, street lamps, as an important part of urban infrastructure, have become crucial to improve their performance and functions. However, traditional street lamps have the following problems:
[0003] First of all, after being exposed to the external environment for a long time, the lampshades of traditional street lamps will gradually accumulate pollutants such as dust, dirt, and insect corpses, which not only affects the lighting effect of the street lamps and reduces the visibility of the road, but also may cause energy waste. At present, manual cleaning is usually used to clean the lampshades of street lamps. This method is not only costly and inefficient, but also has certain safety risks, especially on busy roads, where manual cleaning may interfere with traffic.
[0004] Secondly, street lamps will generate a lot of heat after working for a long time, especially in a high temperature environment. The temperature inside the street lamp may rise sharply, which will not only affect the service life and performance stability of the street lamp, but also may cause safety hazards. For example, excessive temperature may cause damage to the bulb, circuit failure and even fire. The traditional street lamp cooling method mainly relies on natural heat dissipation, which has limited effect and cannot meet the modern street lamp's demand for efficient cooling.
[0005] Finally, in cities, rainwater usually flows directly into the drainage system without being effectively utilized, resulting in great waste. Summary of the invention
[0006] The purpose of the present invention is to provide an energy-saving smart street lamp to solve the problems raised in the prior art.
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] The energy-saving smart street lamp includes a lamp holder, a lamp pole, a cleaning unit and a cooling unit. The lamp holder is placed on a horizontal ground, an inner cylinder is arranged inside the lamp holder, the lamp pole is fixedly installed at one end of the lamp holder away from the horizontal base, and two symmetrical sliding grooves are provided on the inner wall of the lamp pole parallel to the vertical axis. The cleaning unit is fixedly connected to the lamp holder, the cleaning unit is fixedly connected to the lamp pole, the cleaning unit is fixedly connected to the cooling unit, the cleaning unit has the function of cleaning the cooling unit, the cooling unit is fixedly connected to the lamp pole, and the cooling unit has the function of automatic cooling.
[0009] The lamp holder is used to install and fix the lamp pole, and the lamp pole is used to install and fix the cleaning unit and the cooling unit. The cleaning unit is used to clean the dust attached to the surface of the lampshade, and the cooling unit is used to cool the street lamp. In the rainy season in summer, rainwater is collected by the cleaning unit. When there is too much dust attached to the outer surface of the lampshade, resulting in low light intensity, the cleaning unit starts to scrape and clean the dust on the surface of the lampshade to avoid weakening the lighting effect of the street lamp. When the outdoor temperature is high in summer, the cooling unit automatically starts to actively cool down the street lamp to avoid shortening the life of the street lamp due to high temperature.
[0010] Furthermore, the cleaning unit comprises an installation box, a motor, a cam, a gear, an extrusion block, a return spring, a limiting cylinder, a moving rod, a magnetic block 1, a rack 1, a rack 2, a filter plate, a water collecting cylinder, an electromagnet 1, a magnetic block 2 and a spring telescopic tube. The installation box is fixedly installed on the middle outer surface of the lamp pole, the fixed end of the motor is fixedly installed on the inner wall of the installation box, the output end of the motor passes through the installation box and extends into the interior of the lamp pole and is fixedly connected to the gear, the cam is fixedly installed in the middle of the motor output shaft, the cam is installed inside the installation box, the return spring is fixedly connected to the extrusion block at one end away from the horizontal base, and the other end is fixedly connected to the inner surface of the installation box at one end close to the horizontal base, the extrusion block is slidably connected to the limiting cylinder, the limiting cylinder is fixedly installed on the inner surface of the installation box at one end close to the horizontal base, one end of the moving rod is slidably connected to the limiting cylinder parallel to the horizontal axis, and the other end is fixedly connected to the first electrode sheet, the magnetic block 1 The gear is fixedly installed on the side of one end of the limit cylinder away from the moving rod, and the rack one extends into the water collecting cylinder away from the lamp holder at one end and is fixedly connected to the filter plate. The rack one is slidably installed in a sliding groove opened in the lamp pole, and the rack one is meshed with the gear. The rack two is slidably installed in another sliding groove opened in the lamp pole near the horizontal base, and the rack two is meshed with the gear. The filter plate is slidably installed in the water collecting cylinder, and a plurality of groups of filter holes are evenly provided on the surface of the filter plate. The water collecting cylinder is fixedly installed on the end of the lamp pole away from the horizontal base, and a plurality of groups of grooves are provided on the filter plate. The electromagnet one is fixedly installed in the groove, and the spring telescopic tube is fixedly connected to the electromagnet one at one end close to the horizontal base, and is fixedly connected to the magnetic block two at one end away from the horizontal base. The magnetic block two is located directly above the filter holes of the filter plate, and the surface area of the magnetic block two is larger than the filter holes of the filter plate.
[0011] Furthermore, the cleaning unit also includes a coil, a magnet, a pull rope, a guide column, a drainage pipe, a filter, a telescopic spring, a water spray pipe, a scraper, an electromagnet 2, a first electrode sheet and a second electrode sheet. The coil is evenly wound on the outer surface of the inner tube of the lamp holder, the coil is electrically connected to the electromagnet 1, the magnet is installed in the inner tube of the lamp holder, one end of the pull rope passes through the lamp holder and is fixedly connected to the magnet, and the other end bypasses the guide column and is fixedly connected to the end face of the water spray pipe. The guide column is fixedly installed inside the drainage pipe, and one end of the drainage pipe is connected to the water collecting cylinder close to the horizontal foundation 1. The end is conductively connected, and the other end of the cooling unit is flush with the side of the lamp pole. The filter is fixedly installed inside the drainage pipe. One end of the telescopic spring is fixedly connected to the filter, and the other end is fixedly connected to the end face of the water spray pipe. The water spray pipe is slidably installed inside the drainage pipe. The scraper is slidably connected to the cooling unit. The scraper is a magnet block. The electromagnet 2 is fixedly connected to the cooling unit. The second electrode sheet is fixedly installed on the inner wall of the installation box. The second electrode sheet is electrically connected to the electromagnet 2. The current initially passed into the electromagnet 2 is used to adsorb the scraper.
[0012] When too much dust adheres to the surface of the lampshade and the light intensity becomes low, the controller controls the motor to start, which drives the gear to rotate on the one hand, thereby driving the rack 2 to drive the magnet to move upward. During the upward movement of the magnet, the magnetic flux changes, thereby generating a positive current in the coil. The current is transmitted to the electromagnet 1 through the coil, so that the electromagnet 1 is energized and presents a polarity opposite to that of the magnetic block 2. Under the action of the magnetic force, the magnetic block 2 is pulled downward to block the filter holes on the filter plate, so that the filter plate forms a closed plate. The rotation of the gear drives the rack 1 to pull the filter plate downward, thereby squeezing the rainwater in the water collection tube downward. Under the action of pressure, the pressure valve is opened and flows into the drainage pipe. During the upward movement of the magnet, the telescopic spring in the compressed state is released and extended, thereby pushing the water spray pipe to extend to the bottom of the lampshade. Under the pressure of the filter plate, the rainwater in the drainage pipe is sprayed from the water spray pipe to the bottom of the lampshade. On the one hand, the rotation of the motor belt cam periodically pushes the extrusion block downward. When the cam contacts the extrusion block, it pushes the extrusion block to compress the reset spring and move downward along the inside of the limit cylinder, thereby pushing the moving rod to drive the first electrode sheet to contact the second electrode sheet, changing the current direction of the electromagnet two. At this time, the current of the controller is transmitted to the electromagnet two through the first electrode sheet and the second electrode sheet, causing the electromagnet two to change its polarity, thereby pushing the scraper to extend. When the cam does not contact the extrusion block, the moving rod drives the moving rod to move to the left under the action of the magnetic force generated by the magnetic block one, thereby causing the first electrode sheet and the second electrode sheet to separate from each other. At this time, the controller restores the initial current direction of the electromagnet two, thereby causing the electromagnet two to change its polarity and attract the scraper to retract into the straight plate. During the left and right movement of the scraper, the water spray pipe is used to spray water to clean the dust and dirt attached to the lower surface of the lampshade, thereby jointly improving the lighting effect of the street lamp.
[0013] When the cleaning of the street lamp is completed, the controller controls the motor to reverse. On the one hand, the gear drives rack 1 to push the filter plate upward to reset. At this time, rack 2 moves downward to drive the magnet downward, thereby generating a reverse current in the coil. The current is transmitted to electromagnet 1, causing electromagnet 1 to change polarity again, thereby cooperating with the restoring force of the spring telescopic tube itself to push magnetic block 2 to move upward, no longer blocking the filter holes, and rainwater continues to pass through the filter holes on the filter plate into the bottom of the water collection cylinder, thereby not affecting the collection of rainwater. During the downward movement of the magnet, the pull rope is pulled, thereby pulling the water spray pipe to squeeze the telescopic spring and slide into the drainage pipe, thereby avoiding the water spray pipe being directly under the street lamp, causing the lighting effect of the street lamp to deteriorate.
[0014] Furthermore, the cooling unit includes a lampshade, an LED lamp, a refrigerator, a first chamber, a second chamber, a push rod, a conductive plate, a shielding plate, a memory spring, a photoresistor and a long tube. The lampshade is fixedly mounted on the lamp pole. Two front and rear straight plates are arranged on both sides of an end face of the lampshade close to the horizontal base. A rectangular through groove is opened inside the straight plate. The scraper is slidably mounted in the rectangular through groove of the rear straight plate. The second electromagnet is fixedly mounted in the rectangular through groove of the rear straight plate. The LED lamp is fixedly mounted inside the lampshade. The LED lamp divides the inside of the lampshade into a first chamber and a second chamber. The first chamber and the second chamber are connected by a pipeline. The refrigerator The device is fixedly installed inside the first chamber, and the long tube is fixedly installed in the second chamber. One end of the push rod extends out of the long tube, and the other end is provided with a circular plate. The push rod is slidably connected to the long tube, and the circular plate divides the long tube into two left and right chambers. Water is provided inside the right chamber, and the pressures in the left and right chambers of the long tube are the same. The conductive plate is electrically connected to the refrigerator, and the conductive plate is fixedly installed on the inner wall of the lampshade and the push rod on the same axis. The baffle plate is slidably installed in the rectangular through groove of the front straight plate of the lampshade, and the baffle plate is connected to the straight plate through a memory spring. The photoresistor is fixedly installed on the upper surface of the straight plate of the lampshade, and the photoresistor is electrically connected to the memory spring.
[0015] During the day, when the photoresistor detects that the light intensity is too strong, the resistance value becomes smaller, and the current transmitted by the controller through the photoresistor becomes larger, thereby transmitting the current to the memory spring. When the memory spring receives a large current, it expands and stretches, thereby pushing the shielding plate to extend the straight plate to shield the bottom of the lampshade to prevent dust and mosquito corpses from adhering to the lampshade, thereby further preventing the lighting effect of the street lamp from deteriorating. At night, when the photoresistor detects that the light intensity is too low, the resistance value becomes larger, and the current transmitted to the memory spring through the photoresistor is smaller. At this time, the memory spring gradually returns to its initial length, thereby pulling the shielding plate. The plate retracts to the inside of the straight plate and does not block the street lamp to avoid affecting the lighting of the street lamp at night. When the weather is hot, the water in the long tube evaporates and causes the chamber on the right side of the long tube to expand, thereby pushing the push rod to move to the left. When it contacts the conductive plate, the controller transmits current to the conductive plate through the push rod, thereby controlling the refrigerator to release cold air to cool the LED lamp and avoid damage to the street lamp. At the same time, the cold air cools the outer wall of the long tube and re-condenses the water, so that the chamber on the left side of the long tube pushes the circular plate to drive the push rod to move to the right and reset, preparing for the next cooling.
[0016] Furthermore, the moving rod is provided with an inclined surface at an angle to the horizontal axis at one end close to the extrusion block, and the direction is horizontally upward.
[0017] In order to facilitate the extrusion block to move up and down more smoothly in the limiting cylinder, it is convenient to push the moving rod to move rightward, so that the first electrode sheet contacts the second electrode sheet, thereby changing the polarity of the second electromagnet and moving the scraper to the left, thereby cleaning the lampshade and improving the lighting effect.
[0018] Furthermore, the magnetic block 1 and the moving rod are located on the same horizontal axis, and the moving rod is made of iron.
[0019] In order to facilitate the reset of the moving rod under the magnetic force of the magnetic block 1 when it is separated from the extrusion of the extrusion block, the first electrode sheet is contacted and separated from the second electrode sheet, so that the electromagnet 2 continues to receive the reverse current of the controller, thereby pulling the scraper to reset, and the lampshade is cleaned for the second time to improve the lighting effect.
[0020] Furthermore, a sponge is provided on an end surface of the scraper close to the lampshade.
[0021] The sponge has a certain elasticity and can deform according to the shape of the lampshade to better fit the surface of the lampshade. Whether it is a flat lampshade or a curved lampshade, the sponge can closely contact the lampshade to ensure cleaning without dead angles and improve the cleaning effect. At the same time, the sponge is soft and will not damage the lampshade.
[0022] Furthermore, a pressure valve is provided inside the connection between the water collecting cylinder and the drainage pipe.
[0023] When the lampshade needs to be cleaned, the rainwater in the water collection tube can enter the water spray pipe under the pressure of the filter plate and spray under the lampshade to clean the lampshade. When the cleaning is completed, the filter plate no longer generates pressure on the pressure valve, and the rainwater no longer flows out, avoiding the waste of rainwater.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. The present invention rotates the gear in the cleaning unit to make the rack 2 drive the magnet to move upward. On the one hand, a positive current is generated in the coil and transmitted to the electromagnet 1, so that the electromagnet 1 attracts the magnetic block 2 to move downward to block the filter plate. On the other hand, under the action of the pull rope, the telescopic spring is released to push the water spray pipe to the bottom of the lampshade, and at the same time drive the rack 1 to pull the filter plate to move downward, so that rainwater is squeezed downward into the water spray pipe, and then sprayed to the bottom of the lampshade under the pressure of the filter plate. When the motor rotates to make the cam contact with the extrusion block, the moving rod is pushed to drive the second filter plate to move downward. The first electrode sheet contacts the second electrode sheet, changing the current direction of the second electromagnet, causing the second electromagnet to change its polarity, thereby pushing the scraper to extend. When the cam is not in contact with the extrusion block, the moving rod moves leftward on the magnetic block, causing the first electrode sheet to separate from the second electrode sheet. At this time, the controller restores the initial current direction of the second electromagnet, thereby causing the second electromagnet to change its polarity and attracting the scraper to retract into the straight plate. During the left and right movement of the scraper, the water spray pipe is used to spray water to clean the dust and dirt attached to the lower surface of the lampshade, thereby jointly improving the lighting effect of the street lamp.
[0026] 2. When the cleaning of the street lamp is completed, the present invention reverses the gears so that rack 1 drives the filter plate to move upward and reset, and rack 2 drives the magnet to move downward, thereby generating a reverse current in the coil, causing electromagnet 1 to change polarity again, thereby cooperating with the spring telescopic tube so that the magnetic block no longer blocks the filter hole, thereby not affecting the collection of rainwater. During the downward movement of the magnet, the pull rope is pulled to make the water spray pipe slide into the drainage pipe, thereby avoiding the water spray pipe being directly under the street lamp, causing the lighting effect of the street lamp to deteriorate.
[0027] 3. The present invention changes its resistance according to the light intensity through the photoresistor in the cooling unit. Therefore, during the day, when the light intensity is high, the resistance of the photoresistor becomes small, and the memory spring expands and stretches when receiving a large current, thereby pushing the baffle plate to extend out of the straight plate to block the bottom of the lampshade, preventing dust and mosquito corpses from adhering to the lampshade, thereby further preventing the lighting effect of the street lamp from deteriorating. At night, when the light intensity is low, the resistance detected by the photoresistor becomes large, and the memory spring gradually returns to its initial length, thereby pulling the baffle plate back to the inside of the straight plate, not blocking the street lamp, and avoiding affecting the lighting of the street lamp at night.
[0028] 4. In hot weather, the present invention expands the right chamber of the long tube by evaporating the water in the long tube, thereby pushing the push rod to contact the conductive plate to control the operation of the refrigerator, so that the refrigerator releases cold air to cool the LED lamp and avoid damage to the street lamp.

When the outdoor temperature is high in summer, the cooling unit 4 automatically starts to actively cool the street lamp to avoid a shortened life of the street lamp due to high temperature.
[0044] like Figure 2 , 3 , 4, 5, and 6, the cleaning unit 3 includes an installation box 31, a motor 32, a cam 33, a gear 34, an extrusion block 35, a reset spring 36, a limit cylinder 37, a moving rod 38, a magnetic block 1 39, a rack 1 310, a rack 2 311, a filter plate 312, a water collecting cylinder 313, an electromagnet 1 314, a magnetic block 2 315, and a spring telescopic tube 316.

The water collecting cylinder 313 is fixedly installed on the end of the lamp pole 2 away from the horizontal foundation. The filter plate 312 is provided with a plurality of grooves, and the electromagnet 1 314 is fixedly installed in the groove. The spring telescopic tube 316 is fixedly connected to the electromagnet 1 314 at one end close to the horizontal foundation, and is fixedly connected to the magnetic block 2 315 at one end away from the horizontal foundation. The magnetic block 2 315 is located directly above the filter holes of the filter plate 312, and the surface area of the magnetic block 2 315 is larger than the filter holes of the filter plate 312.
[0045] like Figure 7 , 8 9, the cleaning unit 3 also includes a coil 317, a magnet 318, a pull rope 319, a guide column 320, a drainage pipe 321, a filter screen 322, a telescopic spring 323, a water spray pipe 324, a scraper 325, an electromagnet 2 326, a first electrode sheet 327 and a second electrode sheet 328. The coil 317 is evenly wound around the outer surface of the inner tube of the lamp holder 1, the coil 317 is electrically connected to the electromagnet 1 314, the magnet 318 is installed in the inner tube of the lamp holder 1, one end of the pull rope 319 passes through the lamp holder 1 and is fixedly connected to the magnet 318, and the other end bypasses the guide column 320 and is fixedly connected to the end surface of the water spray pipe 324, the guide column 320 is fixedly installed inside the drainage pipe 321, and the drainage pipe 321- One end is conductively connected to one end of the water collecting tube 313 near the horizontal foundation, and the other end is flush with the cooling unit 4 near the lamp pole 2. The filter 322 is fixedly installed inside the drainage pipe 321. One end of the telescopic spring 323 is fixedly connected to the filter 322, and the other end is fixedly connected to the end face of the water spray pipe 324. The water spray pipe 324 is slidably installed inside the drainage pipe 321. The scraper 325 is slidably connected to the cooling unit 4. The scraper 325 is a magnet block. The electromagnet 2 326 is fixedly connected to the cooling unit 4. The second electrode sheet 328 is fixedly installed on the inner wall of the installation box 31. The second electrode sheet 328 is electrically connected to the electromagnet 2 326. The current initially passed into the electromagnet 2 326 is used to adsorb the scraper 325.
[0046] When too much dust adheres to the surface of the lampshade 41, causing the light intensity to decrease, the controller controls the motor 32 to start, which drives the gear 34 to rotate, thereby driving the rack 2 311 to drive the magnet 318 to move upward. During the upward movement of the magnet 318, the magnetic flux changes, thereby generating a positive current in the coil 317. The current is transmitted to the electromagnet 1 314 through the coil 317, so that the electromagnet 1 314 is energized to present a polarity opposite to the magnetic block 2 315. Under the action of the magnetic force, the magnetic block 2 315 is pulled downward to block the filter plate 312. The filter holes are formed so that the filter plate 312 forms a closed plate. The gear 34 rotates and drives the rack 310 to pull the filter plate 312 downward, thereby squeezing the rainwater in the water collecting tube 313 downward. Under the action of pressure, the pressure valve is opened and flows into the drainage pipe 321. During the upward movement of the magnet 318, the telescopic spring 323 in the compressed state is released and extended, thereby pushing the water spray pipe 324 to extend to the bottom of the lampshade 41. Under the pressure of the filter plate 312, the rainwater in the drainage pipe 321 is sprayed from the water spray pipe 324 to the bottom of the lampshade 41. On the other hand, The motor 32 rotates and the cam 33 rotates periodically to push the extrusion block 35 downward. When the cam 33 contacts the extrusion block 35, the extrusion block 35 is pushed to compress the reset spring 36 and move downward along the inside of the limit tube 37, thereby pushing the moving rod 38 to drive the first electrode sheet 327 to contact the second electrode sheet 328, changing the direction of the current delivered to the second electromagnet 326. At this time, the current of the controller is delivered to the second electromagnet 326 through the first electrode sheet 327 and the second electrode sheet 328, causing the second electromagnet 326 to change its polarity, thereby pushing the scraper 325 to extend. When the cam 33 is not in contact with the extrusion block 35, the moving rod 38 is driven to move leftward by the magnetic force generated by the magnetic block 1 39, so that the first electrode sheet 327 and the second electrode sheet 328 are separated from each other. At this time, the controller restores the initial current direction of the electromagnet 2 326, so that the electromagnet 2 326 changes its polarity and attracts the scraper 325 to retract into the straight plate. During the left and right movement of the scraper 325, the water spray pipe 324 sprays water to clean the dust and dirt attached to the lower surface of the lampshade 41, thereby jointly improving the lighting effect of the street lamp.
[0047] When the cleaning of the street lamp is completed, the controller controls the motor 32 to reverse. On the one hand, the gear 34 drives the rack 1 310 to push the filter plate 312 to move upward and reset. At this time, the rack 2 311 moves downward to drive the magnet 318 to move downward, thereby generating a reverse current in the coil 317. The current is transmitted to the electromagnet 1 314, so that the electromagnet 1 314 changes its polarity again, thereby cooperating with the restoring force of the spring telescopic tube 316 itself to push the magnetic block 2 315 to move upward, no longer blocking the filter hole, and the rainwater continues to pass through the filter holes on the filter plate 312 into the bottom of the water collection tube 313, thereby not affecting the collection of rainwater. During the downward movement of the magnet 318, the pull rope 319 is pulled, thereby pulling the water spray pipe 324 to squeeze the telescopic spring 323 and slide into the drainage pipe 321, thereby avoiding the water spray pipe 324 being directly below the street lamp, causing the lighting effect of the street lamp to deteriorate.
[0048] like Fig. 9 , 10 As shown, the cooling unit 4 includes a lampshade 41, an LED lamp 42, a refrigerator 43, a first chamber 44, a second chamber 45, a push rod 46, a conductive plate 47, a shielding plate 48, a memory spring 49, a photoresistor 410 and a long tube 411. The lampshade 41 is fixedly installed on the lamp pole 2. Two front and rear straight plates are arranged on both sides of an end surface of the lampshade 41 close to the horizontal foundation. A rectangular through groove is opened inside the straight plate. The scraper 325 is slidably installed in the rectangular through groove of the rear straight plate. The second electromagnet 326 is fixedly installed in the rectangular through groove of the rear straight plate. The LED lamp 42 is fixedly installed inside the lampshade 41. The LED lamp 42 divides the inside of the lampshade 41 into a first chamber 44 and a second chamber 45. The first chamber 44 and the second chamber 45 are connected by a pipeline. The refrigerator 43 is fixedly installed inside the first chamber 44, the long tube 411 is fixedly installed in the second chamber 45, one end of the push rod 46 extends out of the long tube 411, and the other end is provided with a circular plate, the push rod 46 is slidably connected to the long tube 411, the circular plate divides the long tube 411 into two left and right chambers, water is provided inside the right chamber, the pressures of the left and right chambers of the long tube 411 are the same, the conductive plate 47 is electrically connected to the refrigerator 43, the conductive plate 47 is fixedly installed on the inner wall of the lampshade 41 on the same axis as the push rod 46, the baffle plate 48 is slidably installed in the front straight plate rectangular through groove of the lampshade 41, the baffle plate 48 is connected to the straight plate through a memory spring 49, the photoresistor 410 is fixedly installed on the upper surface of the straight plate of the lampshade 41, and the photoresistor 410 is electrically connected to the memory spring 49.
[0049] During the day, when the photoresistor 410 detects that the light intensity is too high, the resistance value becomes smaller, and the current transmitted by the controller through the photoresistor 410 becomes larger, so that the current is transmitted to the memory spring 49. When the memory spring 49 receives a large current, it expands and stretches, thereby pushing the shielding plate 48 to extend the straight plate to shield the bottom of the lampshade 41, thereby preventing dust and mosquito corpses from adhering to the lampshade 41, thereby further preventing the lighting effect of the street lamp from deteriorating. At night, when the photoresistor 410 detects that the light intensity is too low, the resistance value becomes larger, and the current transmitted to the memory spring 49 through the photoresistor 410 is smaller. At this time, the memory spring 49 gradually returns to its initial length, thereby pulling the shielding plate 4 8 retracts to the inside of the straight plate and does not block the street lamp to avoid affecting the lighting of the street lamp at night. When the weather is hot, the water in the long tube 411 evaporates to expand the chamber on the right side of the long tube 411, thereby pushing the push rod 46 to move to the left. When it contacts the conductive plate 47, the controller transmits current to the conductive plate 47 through the push rod 46, thereby controlling the refrigerator 43 to release cold air to cool the LED lamp 42 to avoid damage to the street lamp. At the same time, the cold air cools the outer wall of the long tube 411 to re-condense the water, so that the chamber on the left side of the long tube 411 pushes the circular plate to drive the push rod 46 to move to the right and reset, preparing for the next cooling.
[0050] like Figure 4 As shown, one end of the moving rod 38 close to the extrusion block 35 is provided with an inclined surface which is 45 degrees to the horizontal axis and is horizontally upward.
[0051] In order to facilitate the extrusion block 35 to move up and down more smoothly in the limiting cylinder 37 and to facilitate pushing the moving rod 38 to move to the right, the first electrode sheet 327 is in contact with the second electrode sheet 328, thereby changing the polarity of the electromagnet 326 and moving the scraper 325 to the left, thereby cleaning the lampshade 41 and improving the lighting effect.
[0052] like Figure 4 As shown, the magnetic block 1 39 and the moving rod 38 are located on the same horizontal axis, and the moving rod 38 is made of iron.
[0053] In order to facilitate the reset of the moving rod 38 under the magnetic force of the magnetic block 1 39 when it is separated from the extrusion of the extrusion block 35, the first electrode sheet 327 is contacted and separated from the second electrode sheet 328, so that the electromagnet 2 326 continues to receive the reverse current of the controller, thereby pulling the scraper 325 to reset, and the lampshade 41 is cleaned for the second time to improve the lighting effect.
[0054] like Fig. 9 As shown, a sponge is provided on one end surface of the scraper 325 close to the lampshade 41 .
[0055] The sponge has a certain elasticity and can be deformed according to the shape of the lampshade 41 to better fit the surface of the lampshade 41. Whether it is a flat lampshade 41 or a curved lampshade 41, the sponge can closely contact the lampshade 41 to ensure cleaning without dead angles and improve the cleaning effect. At the same time, the sponge is soft and will not damage the lampshade 41.
[0056] like Figure 5 As shown, a pressure valve is provided inside the connection between the water collecting cylinder 313 and the drainage pipe 321 .
[0057] In order to clean the lampshade 41 when it is necessary, the rainwater in the water collecting tube 313 can enter the water spray pipe 324 under the pressure of the filter plate 312 and spray to the bottom of the lampshade 41 to clean the lampshade 41. When the cleaning is completed, the filter plate 312 no longer generates pressure on the pressure valve, and the rainwater no longer flows out, thereby avoiding the waste of rainwater.
[0058] Working principle of the present invention:
[0059] When too much dust adheres to the surface of the lampshade 41, causing the light intensity to decrease, the controller controls the motor 32 to start, which drives the gear 34 to rotate, thereby driving the rack 2 311 to drive the magnet 318 to move upward. During the upward movement of the magnet 318, the magnetic flux changes, thereby generating a positive current in the coil 317. The current is transmitted to the electromagnet 1 314 through the coil 317, so that the electromagnet 1 314 is energized and presents a polarity opposite to the magnetic block 2 315. Under the action of the magnetic force, the magnetic block 2 315 is pulled downward to block the filter plate 312. The filter holes of the filter plate 312 form a closed plate. The gear 34 rotates while driving the rack 310 to pull the filter plate 312 downward, thereby squeezing the rainwater in the water collecting tube 313 downward. Under the action of pressure, the pressure valve is opened and flows into the drainage pipe 321. During the upward movement of the magnet 318, the telescopic spring 323 in the compressed state is released and extended, thereby pushing the water spray pipe 324 to extend to the bottom of the lampshade 41. Under the pressure of the filter plate 312, the rainwater in the drainage pipe 321 is sprayed from the water spray pipe 324 to the bottom of the lampshade 41. On the one hand, the motor 32 rotates and the cam 33 rotates periodically to push the extrusion block 35 downward. When the cam 33 contacts the extrusion block 35, the extrusion block 35 is pushed to compress the reset spring 36 and move downward along the inside of the limit tube 37, thereby pushing the moving rod 38 to drive the first electrode sheet 327 to contact the second electrode sheet 328, changing the current direction of the second electromagnet 326. At this time, the current of the controller is transmitted to the second electromagnet 326 through the first electrode sheet 327 and the second electrode sheet 328, so that the second electromagnet 326 changes its polarity, thereby pushing the scraper 325 to extend. When the cam 33 is not in contact with the extrusion block 35, the moving rod 38 is driven to move leftward by the magnetic force generated by the magnetic block 1 39, so that the first electrode sheet 327 and the second electrode sheet 328 are separated from each other. At this time, the controller restores the initial current direction of the electromagnet 2 326, so that the electromagnet 2 326 changes its polarity and attracts the scraper 325 to retract into the straight plate. During the left and right movement of the scraper 325, the water spray pipe 324 sprays water to clean the dust and dirt attached to the lower surface of the lampshade 41, thereby jointly improving the lighting effect of the street lamp.
[0060] When the cleaning of the street lamp is completed, the controller controls the motor 32 to reverse. On the one hand, the gear 34 drives the rack 1 310 to push the filter plate 312 to move upward and reset. At this time, the rack 2 311 moves downward to drive the magnet 318 to move downward, thereby generating a reverse current in the coil 317. The current is transmitted to the electromagnet 1 314, so that the electromagnet 1 314 changes its polarity again, thereby cooperating with the restoring force of the spring telescopic tube 316 itself to push the magnetic block 2 315 to move upward, no longer blocking the filter hole, and the rainwater continues to pass through the filter holes on the filter plate 312 into the bottom of the water collection tube 313, thereby not affecting the collection of rainwater. During the downward movement of the magnet 318, the pull rope 319 is pulled, thereby pulling the water spray pipe 324 to squeeze the telescopic spring 323 and slide into the drainage pipe 321, thereby avoiding the water spray pipe 324 being directly below the street lamp, causing the lighting effect of the street lamp to deteriorate.
[0061] During the day, when the photoresistor 410 detects that the light intensity is too high, the resistance value becomes smaller, and the current transmitted by the controller through the photoresistor 410 becomes larger, so that the current is transmitted to the memory spring 49. When the memory spring 49 receives a large current, it expands and stretches, thereby pushing the shielding plate 48 to extend the straight plate to shield the bottom of the lampshade 41, thereby preventing dust and mosquito corpses from adhering to the lampshade 41, thereby further preventing the lighting effect of the street lamp from deteriorating. At night, when the photoresistor 410 detects that the light intensity is too low, the resistance value becomes larger, and the current transmitted to the memory spring 49 through the photoresistor 410 is smaller. At this time, the memory spring 49 gradually returns to its initial length, thereby pulling the shielding plate 4 8 retracts to the inside of the straight plate and does not block the street lamp to avoid affecting the lighting of the street lamp at night. When the weather is hot, the water in the long tube 411 evaporates to expand the chamber on the right side of the long tube 411, thereby pushing the push rod 46 to move to the left. When it contacts the conductive plate 47, the controller transmits current to the conductive plate 47 through the push rod 46, thereby controlling the refrigerator 43 to release cold air to cool the LED lamp 42 to avoid damage to the street lamp. At the same time, the cold air cools the outer wall of the long tube 411 to re-condense the water, so that the chamber on the left side of the long tube 411 pushes the circular plate to drive the push rod 46 to move to the right and reset, preparing for the next cooling.
