Description

Technical Field

[0001] This invention relates to the field of lighting fixture technology, specifically to a self-cleaning lighting fixture and its usage method. Background Technology

[0002] With the widespread use of lighting equipment, whether in urban roads, squares, large factories, or outdoor landscape areas, lighting fixtures are exposed to complex outdoor environments full of dust, stains, and insect remains for a long time. Traditional lighting fixtures, including streetlights, courtyard lights, high-mast lights, and other types of outdoor lighting fixtures, as well as some indoor high-position lighting fixtures, have long faced severe challenges in cleaning their exterior walls, which has become a key problem restricting lighting efficiency and maintenance efficiency.

[0003] Looking at the current state of light fixture exterior cleaning, traditional cleaning methods mainly rely on manual, periodic work at heights. Using rags, cleaning agents, and simple cleaning tools, the outer shell and light-transmitting cover of the light fixture are wiped clean one by one. This cleaning mode has many insurmountable drawbacks. On the one hand, manual cleaning is extremely inefficient. Faced with a large number of lighting fixtures, cleaning personnel need to spend a lot of time operating them one by one, which is difficult to meet the high-frequency cleaning needs. Especially in areas with dense lighting fixtures, such as main urban roads and large industrial parks, the progress of cleaning operations is seriously delayed. On the other hand, the cost of manual cleaning is high. Not only does it require a large investment of manpower, but it also requires the use of climbing equipment and professional cleaning consumables. The long-term accumulated labor costs, equipment maintenance costs, and consumable costs place a heavy economic burden on the operation and maintenance units.

[0004] More importantly, the accuracy and comprehensiveness of manual cleaning cannot be guaranteed, and omissions are very likely to occur. The installation locations of light fixtures are often complex and diverse, with some fixtures located at heights, in narrow gaps, or in irregularly shaped structures. When working manually, the limited field of vision and operating space make it difficult to thoroughly clean the corners, grooves, and edges of the light-transmitting covers. In addition, the cycle of manual cleaning depends entirely on manual scheduling and lacks a scientific and precise timing mechanism. The cleaning interval is difficult to control, resulting in either overly frequent cleaning that wastes resources or excessively long cleaning intervals that lead to the accumulation of dirt, which seriously affects the lighting effect of the light fixtures.

[0005] Therefore, the present invention provides a self-cleaning lighting fixture and its method of use to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a self-cleaning lighting fixture and its usage method, so as to solve the problem of automatically cleaning the outer wall of the lighting fixture at regular intervals and avoiding omissions.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A self-cleaning lighting fixture, comprising: A lamp body, comprising a lamp holder and a lamp fixture, wherein the lamp fixture is installed inside the lamp holder; A cleaning box is installed on one side of the bottom of the lamp holder. A reciprocating screw is rotatably connected inside the box. The reciprocating screw is driven by a bidirectional screw. The bidirectional screw is rotatably connected to the outer wall of the cleaning box. A cleaning frame is threaded onto the outer wall of the bidirectional screw for intermittently and periodically cleaning the outer wall of the lamp. The fixing component includes a fixing screw, a reinforcing block, and a reinforcing shaft. The reinforcing shaft is rotatably connected inside the lamp holder and its bottom is located inside the cleaning box. The reinforcing shaft is drivenly connected to the fixing screw. The fixing screw is on the inner side wall of the lamp holder and is drivenly connected to the cleaning frame. The reinforcing block is threadedly connected to the outer wall of the fixing screw and is used to reinforce the lamp. This device, through the setting of a reciprocating lead screw, can periodically and cyclically drive a bidirectional lead screw to rotate, enabling the bidirectional lead screw to automatically clean the outer wall of the lamp periodically. This avoids damage to the lamp or obstruction of vision caused by prolonged and uninterrupted cleaning. Through the intermittent transmission between the bidirectional lead screw and the reciprocating lead screw, this device achieves intermittent and timed automatic cleaning, enabling cyclical cleaning and avoiding impact on lighting. At the same time, to prevent the lamp from falling off or loosening due to prolonged use, this device can automatically reinforce the lamp during cleaning, ensuring stability for long-term use.

[0008] Preferably, the outer wall of the reciprocating screw is slidably connected to a slide cylinder, the inner wall of the slide cylinder is provided with friction grooves to slow down the sliding of the slide cylinder, and the bottom of the slide cylinder is connected to a return spring through a bearing, the bottom of the return spring being fixedly connected to the inner bottom wall of the cleaning box. A drive bevel gear is installed on the outer wall of the slide cylinder. The drive bevel gear is meshed with a cleaning bevel gear. The cleaning bevel gear is installed on the outer wall of one end of the bidirectional lead screw. A micro motor is fixedly installed on the inner top wall of the cleaning box. The output end of the micro motor is fixedly connected to the top of the reciprocating screw. A pusher is threadedly connected to the outer wall of the upper part of the reciprocating screw, and the pusher abuts against the top of the slide cylinder. When in use, this device activates a micro motor, which can be powered by an external power source or a solar panel battery. This micro motor drives a reciprocating screw to rotate continuously. During this rotation, the abutment on the outer wall of the device reciprocates up and down. When it reaches the lower part of the reciprocating screw, the abutment abuts against the top of the slide cylinder, causing it to move downwards. At this point, the drive bevel gear disengages from the cleaning bevel gear, the bidirectional screw loses its power source, and stops rotating. The cleaning device then stops cleaning. When the abutment returns to its original position, the slide cylinder returns to its original position under the action of a return spring. The inner wall of the slide cylinder has friction grooves that limit the return time of the slide cylinder, creating a time interval between the return of the abutment and the return of the slide cylinder. The continuous rotation of the micro motor then drives the bidirectional screw to rotate after the slide cylinder returns to its original position, allowing the cleaning device to automatically clean the outer wall of the lamp. This device, through the design of the sliding cylinder, allows the sliding cylinder and the bidirectional lead screw to reciprocate and engage repeatedly during the up-and-down repositioning of the support frame. Furthermore, during the repositioning of the support frame, the sliding cylinder can reposition intermittently, ensuring that after each repositioning, the rotation of the bidirectional lead screw only drives the cleaning frame to rotate a certain number of times, preventing the cleaning frame from remaining in different positions. The intermittent cleaning of the cleaning frame in this device can avoid damage to the outer wall of the lamp caused by long-term frequent cleaning.

[0009] Preferably, a telescopic plate is slidably connected to the inner top wall of the cleaning rack, friction texture is provided on the outer wall of the telescopic plate, and an adaptive scraping plate is slidably connected to the inner top wall of the telescopic plate through a scraping spring; The telescopic plate has a retractable frame and an upper top frame fixedly installed at both ends of its bottom. A retraction groove is provided on the outer wall of the retraction frame. The inner wall of the retraction groove matches the inclined end of the retraction inclined block. The retraction inclined block slides inside the cleaning frame. The thickness of the retraction inclined block decreases from the outside to the inside. A retraction plate is fixedly installed at one end of the retraction inclined block. The retraction plate matches the side wall of the cleaning box. The outer wall of the upper top frame is provided with an upper top groove, which matches the inclined end of the upper top inclined plate. The upper top inclined plate is the opposite of the retractable inclined block structure. One end of the upper top inclined plate is equipped with an upper top plate, which matches the outer wall of the cleaning frame. In its initial state, the cleaning frame of this device is located on the side wall of the cleaning box, with the telescopic plate inside the cleaning frame in a retracted state. When the bidirectional screw rotates, it will cause the cleaning frame to move, and the telescopic plate will remain retracted. At the same time, the adaptive scraping plate will not contact the outer wall of the lamp. When the two cleaning frames are facing each other, the upper top plates will abut against each other, causing the upper inclined plate to gradually increase its contact surface with the upper top groove, thus causing the telescopic plate to move upward. The telescopic plate will then cause the adaptive scraping plate to move upward, and the adaptive scraping plate will abut against the outer wall of the lamp. When the cleaning frame returns to its original position, the adaptive scraping plate will scrape the outer wall of the lamp. When the cleaning frame has finished scraping, and the cleaning frame is located on the outer wall of the cleaning box, the retractable plate will insert into the inside of the cleaning box and abut against the inner wall of the cleaning box. The inclined surface of the retractable block and the lower contact surface of the retractable groove will gradually increase, thus causing the telescopic plate to move inward and retract. At this time, the telescopic plate is in an inward retracted state, making it convenient for the next scraping use. When the cleaning rack is located on one side of the cleaning box, the telescopic plate of this device is in an inward-retracted state to facilitate scraping. When the two cleaning racks are facing each other, the telescopic plate can extend to achieve the scraping function. Through these two states, the scraping can reach the farthest part of the outer wall of the lamp, and the scraped debris can be collected by the collection box, avoiding the phenomenon that the collection box is located outside the scraper and the debris cannot be collected. When the cleaning rack slides outward, it does not scrape or collect debris. When it returns to its original position, it scrapes with the scraper, so that the scrapers on the upper parts of the two cleaning racks face each other, scraping the outer wall of the lamp in all directions to avoid omissions, and collecting debris during scraping.

[0010] Preferably, a collection box is installed at one end of the adaptive scraper, and a scraper is installed at the top end of the collection box; A drive wheel is rotatably connected to the center of the top of the collection box. A drive shaft is installed at the axis of the drive wheel. The drive shaft is driven and connected to a linkage shaft via a drive belt. The linkage shaft is rotatably connected to the inner side wall of the collection box. The linkage shaft is driven and connected to an exhaust fan via bevel gears. The exhaust fan is rotatably connected to the inner bottom wall of the collection box. A collection cloth bag is installed at the bottom of the collection box. A release screw is rotatably connected to the inner wall of the collection box. The release screw is driven to the linkage shaft through a one-way bevel gear. A worm spring is installed on the outer wall at the bottom of the release screw. The other end of the worm spring is connected to the bottom of the collection box. A threaded block is threadedly connected to the outer wall of the lead screw, a sealing plate is installed on the top of the threaded block, the sealing plate is slidably connected to the top of the collection box, and a guide plate is fixedly installed on the top of the sealing plate. When the cleaning rack resets and scrapes, the scraper scrapes the outer wall of the lamp, while the drive wheel rotates against the outer wall, causing the drive shaft to rotate the exhaust fan. The collection box absorbs and collects the scraped impurities, and the guide plate guides the flow to form a negative pressure fluid channel. The collection box is located on the scraping side of the scraper for easy collection, preventing missed collection and splashing of impurities. During collection, the device disengages the screw, causing the sealing plate to shift. The top of the collection box is open for easy collection. After completion, it can automatically close to prevent impurities inside from flying out. When not scraping, it achieves a sealing function. When the cleaning frame is repositioned, the rotation of the drive wheel can drive the release screw to rotate through the one-way bevel gear. When the drive wheel disengages from the lamp, the release screw is reset and rotated under the action of the worm spring, thereby sealing the top of the collection box with the sealing plate. When the cleaning frame moves outward, the one-way bevel gear on the release screw will not drive the release screw to rotate, thus keeping the sealing plate sealed.

[0011] Preferably, the retractable plate has external teeth on its sidewall; The reinforcing shaft is located on the outer wall of one end inside the cleaning box and is unidirectionally connected to a reinforcing gear, which matches the external gear.

[0012] Preferably, the reinforcing shaft has a reinforcing cavity inside, and a reinforcing wedge is slidably connected inside the reinforcing cavity. A reinforcing spring is fixedly installed at one end of the reinforcing wedge inside the reinforcing cavity, and the other end of the reinforcing spring is fixedly connected to the inner wall of the reinforcing cavity. The inner wall of the reinforced gear is provided with a reinforcing groove, which matches the reinforcing block; When this device is in use, as the cleaning frame moves towards the cleaning box, the retractable plate will insert into the interior of the cleaning box. At this time, the external teeth on the outer wall of the retractable plate will mesh with the reinforcing gear, causing the reinforcing gear to rotate. When the retractable plate slides out, the inclined surface of the reinforcing wedge on the inner wall of the reinforcing shaft is opposite to the inclined surface of the reinforcing groove, so that the rotation of the reinforcing gear will not drive the reinforcing shaft to rotate. The one-way drive connection here of this device is the same as the one-way bevel gear structure on the disengagement screw.

[0013] Preferably, the top of the reinforcing shaft is connected to the fixing screw via bevel teeth, the outer wall of the fixing screw is engaged with the fixing box, the fixing box is installed on the inner wall of the lamp holder, a second spiral spring is installed on the outer wall of one end of the fixing screw, and the other end of the second spiral spring is fixedly connected to the inner side wall of the lamp holder. The reinforcing block abuts against the outer wall of the top of the lamp.

[0014] Preferably, a fixing plate is fixedly installed on the outer wall of the fixing screw, and the bottom of one end of the fixing plate is set as an arc surface and the top is a straight surface; The fixed box has a second fixed plate that is slidably connected inside. One end of the second fixed plate matches one end of the first fixed plate. A fixed spring is fixedly installed on one end of the second fixed plate, and the other end of the fixed spring is fixedly connected to the inner side wall of the fixed box. When the fixed screw rotates in the forward direction, the arc-shaped end of the first fixed plate abuts against the arc-shaped end of the second fixed plate, causing the second fixed plate to shift inward under force. When the fixed screw stops rotating, the straight surface of the first fixed plate aligns with the straight surface of one end of the second fixed plate, and the second fixed plate engages with the first fixed plate, thus limiting the movement of the fixed screw. This prevents the screw from detaching due to reverse rotation caused by external vibrations after reinforcement, ensuring the device's fixing effect. Furthermore, when replacing the light fixture, pulling the second fixed plate releases the screw from its engagement, and the spiral spring causes the screw to reverse, facilitating installation and disassembly.

[0015] A method for using a self-cleaning lighting fixture includes the following steps: Step A: Start the micro motor, and the reciprocating screw will drive the bidirectional screw to rotate; Step B: The cleaning rack moves back and forth to clean the outer wall of the light fixture in a reciprocating cycle; Step C: The collection box collects the cleaned impurities to prevent them from falling out; Step D: The light fixtures are secured by reinforcing blocks, which automatically reinforces them and prevents them from coming loose during cleaning.

[0016] The beneficial effects of this invention are as follows: 1. This device, through the setting of a reciprocating lead screw, can periodically and cyclically drive a bidirectional lead screw to rotate, enabling the bidirectional lead screw to automatically clean the outer wall of the lamp periodically. This avoids damage to the lamp or obstruction of vision caused by prolonged and uninterrupted cleaning. Through the intermittent transmission between the bidirectional lead screw and the reciprocating lead screw, this device achieves intermittent and timed automatic cleaning, enabling cyclic cleaning and avoiding impact on lighting. At the same time, to prevent the lamp from falling off or loosening due to prolonged use, this device can automatically reinforce the lamp during cleaning, ensuring stability for long-term use.

[0017] 2. This device, through the setting of the sliding cylinder, enables the sliding cylinder and the bidirectional screw to reciprocate and engage repeatedly during the up-and-down reciprocating movement of the top support frame. When the top support frame resets, the sliding cylinder can reset intermittently, so that after each reset, the rotation of the bidirectional screw can only drive the cleaning frame to rotate a certain number of times, avoiding the cleaning frame from staying in different positions. The cleaning frame of this device, through intermittent cleaning, can avoid the phenomenon of damage to the outer wall of the lamp caused by long-term frequent cleaning.

[0018] 3. When the cleaning rack is located on one side of the cleaning box, the telescopic plate of this device is in an inward-retracted state to facilitate scraping. When the two cleaning racks are facing each other, the telescopic plate can extend to achieve the scraping function. Through the setting of these two states, the scraping can reach the farthest part of the outer wall of the lamp. During scraping, the scraped material can be collected by the collection box, avoiding the phenomenon that the collection box is located outside the scraper, which would prevent the scraped impurities from being collected. When the cleaning rack slides outward, it does not scrape or collect the material. When it returns to its original position, it scrapes the material by bringing the scrapers on the upper parts of the two cleaning racks together to scrape the outer wall of the lamp from all directions, avoiding any omissions, and collecting the material during scraping.

[0019] 4. When the cleaning rack is resetting and scraping, the scraper scrapes the outer wall of the lamp, while the drive wheel rotates against the outer wall of the lamp, causing the drive shaft to drive the exhaust fan to rotate. The collection box absorbs and collects the scraped impurities, and the guide plate guides the flow to form a negative pressure fluid channel. The collection box is located on the scraping side of the scraper, which facilitates collection and avoids missed collection and splashing of impurities. At the same time, during collection, the device can disengage the screw to move the sealing plate, and the upper part of the collection box is in an open state for easy collection. After collection, it can automatically close to prevent impurities inside from flying out. When not scraping, it achieves a sealing function.

[0020] 5. When the fixed screw rotates in the forward direction, the arc-shaped end of the first fixed plate will abut against the arc-shaped end of the second fixed plate, causing the second fixed plate to shift inward under force. When the fixed screw stops rotating, the straight surface of the first fixed plate will face the straight surface of one end of the second fixed plate, and the second fixed plate will abut against and lock the first fixed plate. This limits the movement of the fixed screw and prevents it from detaching due to reverse rotation caused by external vibrations after reinforcement. This ensures the fixing effect of the device. When it is necessary to replace the lamp, pulling the second fixed plate will release the locking mechanism of the fixed screw. Under the action of the second spiral spring, the fixed screw will reverse, facilitating installation and disassembly. Attached Figure Description

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] A self-cleaning lighting fixture, as shown in the attached image. Figure 1-10As shown, it includes: The lamp body includes a lamp holder 1 and a lamp fixture 2, with the lamp fixture 2 installed inside the lamp holder 1; The cleaning box 3 is installed on one side of the bottom of the lamp holder 1. A reciprocating screw 4 is rotatably connected inside the box. The reciprocating screw 4 is driven by a bidirectional screw 5. The bidirectional screw 5 is rotatably connected to the outer wall of the cleaning box 3. A cleaning frame 6 is threadedly connected to the outer wall of the bidirectional screw 5 for intermittently and periodically cleaning the outer wall of the lamp 2. The fixing component includes a fixing screw 7, a reinforcing block 8, and a reinforcing shaft 9. The reinforcing shaft 9 is rotatably connected to the inside of the lamp holder 1, and its bottom is located inside the cleaning box 3. The reinforcing shaft 9 is drivenly connected to the fixing screw 7. The fixing screw 7 is on the inner side wall of the lamp holder 1 and is drivenly connected to the cleaning frame 6. The reinforcing block 8 is threadedly connected to the outer wall of the fixing screw 7 and is used to reinforce the lamp 2. This device, through the reciprocating lead screw 4, can periodically and cyclically drive the bidirectional lead screw 5 to rotate, enabling the bidirectional lead screw 5 to periodically and automatically clean the outer wall of the lamp 2. This avoids damage to the lamp or obstruction of vision caused by prolonged and uninterrupted cleaning. Through the intermittent transmission between the bidirectional lead screw 5 and the reciprocating lead screw 4, this device achieves intermittent and timed automatic cleaning, enabling cyclic cleaning and avoiding impact on lighting. At the same time, to prevent the lamp 2 from falling off or loosening due to prolonged use, this device can automatically reinforce the lamp 2 during cleaning, ensuring stability for long-term use.

[0025] As attached Figure 3-4 As shown, a slide cylinder 401 is slidably connected to the upper limit of the outer wall of the reciprocating screw 4. Friction grooves are provided on the inner wall of the slide cylinder 401 to slow down the sliding of the slide cylinder 401. A return spring 402 is connected to the bottom of the slide cylinder 401 through a bearing. The bottom of the return spring 402 is fixedly connected to the inner bottom wall of the cleaning box 3. A drive bevel gear 403 is installed on the outer wall of the slide cylinder 401. The drive bevel gear 403 is meshed with the cleaning bevel gear 501. The cleaning bevel gear 501 is installed on the outer wall of one end of the bidirectional lead screw 5. A micro motor 404 is fixedly installed on the inner top wall of the cleaning box 3. The output end of the micro motor 404 is fixedly connected to the top of the reciprocating screw 4. A pusher 405 is threadedly connected to the outer wall of the upper part of the reciprocating screw 4. The pusher 405 pushes against the top of the slide cylinder 401. In use, this device is activated by starting the micro motor 404, which can be driven by an external power source or a solar panel battery. The micro motor 404 drives the reciprocating screw 4 to rotate continuously. During this rotation, the abutment frame 405 on its outer wall will reciprocate up and down. When it reaches the lower part of the reciprocating screw 4, the abutment frame 405 will abut against the top of the slide cylinder 401, causing it to move downwards. At this point, the drive bevel gear 403 disengages from the cleaning bevel gear 501, and the bidirectional screw 5 loses its driving force. The power source causes the bidirectional lead screw 5 to stop rotating, and the cleaning frame 6 is in a stopped cleaning state. When the abutment frame 405 returns to its original position, the slide cylinder 401 returns to its original position under the action of the return spring 402. At the same time, the inner wall of the slide cylinder 401 is provided with friction texture, which can limit the return time of the slide cylinder 401. This creates a certain time interval between the return of the abutment frame 405 and the return of the slide cylinder 401. Subsequently, the continuous rotation of the micro motor 404 enables the bidirectional lead screw 5 to rotate after the slide cylinder 401 returns to its original position, and the cleaning frame 6 automatically cleans the outer wall of the lamp 2. This device, through the setting of the slide cylinder 401, enables the slide cylinder 401 and the bidirectional lead screw 5 to reciprocate and engage repeatedly when the top support frame 405 moves up and down in a cyclical manner. When the top support frame 405 resets, the slide cylinder 401 can reset intermittently, so that after each reset, the rotation of the bidirectional lead screw 5 can only drive the cleaning frame 6 to rotate a certain number of times, avoiding the cleaning frame 6 from staying in different positions. The cleaning frame 6 of this device can avoid the phenomenon of damage to the outer wall of the lamp 2 caused by long-term frequent cleaning through intermittent cleaning.

[0026] As attached Figure 5-6 As shown, a telescopic plate 601 is slidably connected to the inner top wall of the cleaning frame 6. Friction textures are provided on the outer wall of the telescopic plate 601. An adaptive scraping plate 609 is slidably connected to the inner top wall of the telescopic plate 601 through a scraping spring 610. The retractable frame 602 and the top frame 603 are fixedly installed at both ends of the bottom of the telescopic plate 601, respectively. A retraction groove 604 is provided on the outer wall of the retraction frame 602. The inner wall of the retraction groove 604 matches the inclined end of the retraction inclined block 605. The retraction inclined block 605 slides inside the cleaning frame 6. The thickness of the retraction inclined block 605 decreases from the outside to the inside. A retraction plate 606 is fixedly installed at one end of the retraction inclined block 605. The retraction plate 606 matches the side wall of the cleaning box 3. An upper top groove 607 is provided on the outer wall of the upper top frame 603. The upper top groove 607 matches the inclined end of the upper top inclined plate 608. The upper top inclined plate 608 has the opposite structure to the retractable inclined block 605. An upper top plate is installed at one end of the upper top inclined plate 608. The upper top plate matches the outer wall of the cleaning frame 6. In its initial state, the cleaning frame 6 of this device is located on the side wall of the cleaning box 3, with the telescopic plate 601 inside the cleaning frame 6 and in a retracted state. When the bidirectional screw 5 rotates, it will cause the cleaning frame 6 to move. At this time, the telescopic plate 601 is in a retracted state, and the adaptive scraping plate 609 does not contact the outer wall of the lamp 2. When the two cleaning frames 6 are facing each other, the upper top plates abut against each other, causing the upper top inclined plate 608 to gradually increase its abutment surface with the upper top groove 607, thereby causing the telescopic plate 601 to move upward. At this time, the telescopic plate 601 drives the adaptive scraping plate 609 to move upward. The scraping plate 609 should be moved upward, and the adaptive scraping plate 609 abuts against the outer wall of the lamp 2. When the cleaning frame 6 is reset and moved, the adaptive scraping plate 609 scrapes the outer wall of the lamp 2. When the cleaning frame 6 finishes scraping, and the cleaning frame 6 is located on the outer wall of the cleaning box 3, the retractable plate 606 will be inserted into the interior of the cleaning box 3 and abut against the inner wall of the cleaning box 3. The inclined surface of the retractable inclined block 605 and the lower abutting surface of the retractable groove 604 gradually increase, thereby causing the telescopic plate 601 to move inward and retract. At this time, the telescopic plate 601 is in an inward retracted state, which is convenient for scraping next time. When the cleaning rack 6 is located on one side of the cleaning box 3, the telescopic plate 601 of this device is in an inward retracted state to facilitate scraping. When the two cleaning racks 6 are facing each other, the telescopic plate 601 can extend to achieve the scraping function. Through the setting of these two states, the scraping can reach the farthest part of the outer wall of the lamp 2. During scraping, the scraped material can be collected by the collection box, avoiding the phenomenon that the collection box is located outside the scraper, which would prevent the scraped impurities from being collected. When the cleaning rack 6 slides outward, it does not scrape or collect the material. When it resets, it scrapes the material by making the scrapers on the upper parts of the two cleaning racks 6 face each other, scraping the outer wall of the lamp 2 from all directions to avoid omissions, and collecting the material during scraping.

[0027] As attached Figure 5-7 As shown, a collection box 611 is installed at one end of the adaptive scraper 609, and a scraper 612 is installed at the top end of the collection box 611. A drive wheel 613 is rotatably connected to the center of the top of the collection box 611. A drive shaft 614 is installed at the axis of the drive wheel 613. The drive shaft 614 is driven to the linkage shaft 615 via a drive belt 617. The linkage shaft 615 is rotatably connected to the inner side wall of the collection box 611. The linkage shaft 615 is driven to the exhaust fan 616 via bevel gears. The exhaust fan 616 is rotatably connected to the inner bottom wall of the collection box 611. A collection bag 618 is installed at the bottom of the collection box 611. A release screw 619 is rotatably connected to the inner wall of the collection box 611. The release screw 619 is driven to the linkage shaft 615 through a one-way bevel gear. A worm spring 620 is installed on the outer wall at the bottom of the release screw 619. The other end of the worm spring 620 is connected to the bottom of the collection box 611. A threaded block 621 is threadedly connected to the outer wall of the lead screw 619. A sealing plate 622 is installed on the top of the threaded block 621. The sealing plate 622 is slidably connected to the top of the collection box 611. A guide plate 623 is fixedly installed on the top of the sealing plate 622. When the cleaning frame 6 is resetting and scraping, the scraper 612 scrapes the outer wall of the lamp 2, while the drive wheel 613 rotates against the outer wall of the lamp 2, causing the drive shaft 614 to drive the exhaust fan 616 to rotate. The collection box 611 absorbs and collects the scraped impurities, and the guide plate 623 guides the flow to form a negative pressure fluid channel. The collection box 611 is located on the scraping side of the scraper 612 for easy collection, preventing missed collection and splashing of impurities. During collection, the device allows the disengaged screw 619 to move the sealing plate 622, and the upper part of the collection box 611 is open for easy collection. After completion, it can automatically close to prevent impurities inside from flying out. When not scraping, it achieves a sealing function. When the cleaning frame 6 is repositioned, the rotation of the drive wheel 613 can drive the release screw 619 to rotate through the one-way bevel gear. When the drive wheel 613 disengages from the lamp 2, the release screw 619 is reset and rotated under the action of the worm spring 620, which in turn causes the sealing plate 622 to seal the top of the collection box 611. When the cleaning frame 6 moves outward, the one-way bevel gear on the release screw 619 will not drive the release screw 619 to rotate, thus keeping the sealing plate 622 sealed.

[0028] As attached Figure 4-6 and attached Figure 8 As shown, external teeth are provided on the side wall of the retractable plate 606; The reinforcing shaft 9 is located on the outer wall of one end inside the cleaning box 3 and is connected to a reinforcing gear 901 in a one-way drive. The reinforcing gear 901 matches the external gear.

[0029] As attached Figure 9 As shown, a reinforcement cavity 902 is provided inside the reinforcement shaft 9. A reinforcement wedge 903 is slidably connected inside the reinforcement cavity 902. A reinforcement spring 904 is fixedly installed at one end of the reinforcement wedge 903 inside the reinforcement cavity 902. The other end of the reinforcement spring 904 is fixedly connected to the inner wall of the reinforcement cavity 902. The inner wall of the reinforced gear 901 is provided with a reinforced inclined groove 905, which matches the reinforced inclined block 903; When this device is in use, when the cleaning frame 6 moves towards the cleaning box 3, the retractable plate 606 will be inserted into the interior of the cleaning box 3. At this time, the external teeth on the outer wall of the retractable plate 606 will mesh with the reinforcing gear 901, and the reinforcing gear 901 will rotate. When the retractable plate 606 slides out, the inclined surface of the reinforcing inclined block 903 on the inner wall of the reinforcing shaft 9 is opposite to the inclined surface of the reinforcing inclined groove 905, so that the reinforcing gear 901 will not drive the reinforcing shaft 9 to rotate when it rotates. The one-way drive connection here of this device is the same as the one-way bevel gear structure on the disengagement screw 619.

[0030] As attached Figure 8 As shown, the top of the reinforcing shaft 9 is connected to the fixing screw 7 by bevel teeth. The outer wall of the fixing screw 7 is snapped into the fixing box 701. The fixing box 701 is installed on the inner wall of the lamp holder 1. A second worm spring 705 is installed on the outer wall of one end of the fixing screw 7. The other end of the second worm spring 705 is fixedly connected to the inner wall of the lamp holder 1. The reinforcing block 8 abuts against the outer wall of the top of the lamp 2.

[0031] As attached Figure 10 As shown, a fixing plate 702 is fixedly installed on the outer wall of the fixing screw 7. The bottom of one end of the fixing plate 702 is set as an arc surface and the top is a straight surface. The fixed box 701 has a sliding connection to a second fixed plate 703. One end of the second fixed plate 703 matches one end of the first fixed plate 702. A fixed spring 704 is fixedly installed on one end of the second fixed plate 703. The other end of the fixed spring 704 is fixedly connected to the inner side wall of the fixed box 701. When the fixed screw 7 rotates in the forward direction, the arc-shaped end of the first fixed plate 702 abuts against the arc-shaped end of the second fixed plate 703, causing the second fixed plate 703 to displace inward under force. When the fixed screw 7 stops rotating, the straight surface of the first fixed plate 702 faces the straight surface of one end of the second fixed plate 703, and the second fixed plate 703 abuts and engages with the first fixed plate 702, thus limiting the movement of the fixed screw 7. This prevents the fixed screw 7 from detaching due to reverse rotation caused by external vibrations after reinforcement is completed, ensuring the fixing effect of the device. At the same time, when it is necessary to replace the lamp 2, pulling the second fixed plate 703 releases the engagement of the fixed screw 7. Under the action of the second spiral spring 705, the fixed screw 7 reverses, facilitating installation and disassembly.

[0032] A method for using a self-cleaning lighting fixture includes the following steps: Step A: By starting the micro motor 404, the reciprocating screw 4 drives the bidirectional screw 5 to rotate; Step B: The cleaning rack 6 moves back and forth to clean the outer wall of the light fixture 2 in a reciprocating cycle; Step C: Collection box 611 collects the cleaned impurities to prevent them from falling out; Step D: The lamp 2 is automatically secured by the reinforcing block 8, preventing detachment during cleaning.
