Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-8 , the present invention provides a technical solution: a downhole lighting device with cleaning and power generation functions, including a main body housing 1 and a power generation component housing 2, made of high-strength explosion-proof aluminum alloy (such as 6061-T6), taking into account both lightweight and impact resistance. The power generation component housing 2 is arranged on the side surface of the main body housing 1. An LED lamp assembly, a storage battery, a circuit board, etc. are arranged inside the main body housing 1, and its internal components are substantially the same as those of the existing downhole lighting devices.

[0026] A lamp cover 3 corresponding to the LED lamp assembly is arranged on the main body housing 1. A screw groove is opened on the inner side of the main body housing 1 above the lamp cover 3. A ball screw 4 is rotatably arranged in the screw groove. The outside of the nut of the ball screw 4 is fixedly provided with a sliding cleaning brush 5. The height of the sliding cleaning brush 5 covers the entire height of the outside of the lamp cover 3. The inner surface of the sliding cleaning brush 5 is uniformly provided with bristles, and the bristles are preferably nylon 66 + carbon fiber reinforced, wear-resistant and antistatic. By moving the sliding cleaning brush 5, the surface of the lamp cover 3 is cleaned to prevent the lighting device from being affected by pollution accumulation and affecting the lighting effect.

[0027] One end of the ball screw 4 is connected to a bearing provided inside the main body housing 1, and the other end penetrates into the inside of the power generation component housing 2. A movable gear 8 driven by the power generation component to rotate is provided on a section of the ball screw 4 located inside the power generation component housing 2. The sliding cleaning brush 5 is driven to slide by the ball screw 4. A movable gear 8 driven by the power generation component to rotate is provided on the ball screw 4. When manually generating electricity and storing energy through the power generation component or powering the LED lamp component, the ball screw 4 can be driven to rotate by the movable gear 8, thereby driving the sliding cleaning brush 5 to move to clean the surface of the lamp cover 3. At the same time of cleaning the surface of the lamp cover 3, electricity can also be generated and stored through the power generation component, extending the battery life of the lighting device, ensuring a good lighting environment for underground work, and being beneficial for working underground for a long time.

[0028] In a preferred technical solution, the power generation component includes an internal gear ring 13 rotatably provided inside the power generation component housing 2. The internal gear ring 13 is rotatably provided on a fixed shaft 35, and the fixed shaft 35 is installed inside the power generation component housing 2. A rotating block 14 is also rotatably provided outside the fixed shaft 35. At least one pawl groove is provided on the outer surface of the rotating block 14. A pawl 15 matching the internal gear ring 13 is provided in the pawl groove. A corresponding spring is provided between the pawl 15 and the pawl groove, so that the pawl 15 always has a tendency to rotate outward, so as to be easily snapped into the internal gear ring 13 to make the rotating block 14 rotate following the internal gear ring 13.

[0029] A main gear 12 is fixedly provided on the outer surface of the rotating block 14. A main shaft 16 is fixedly installed at the center of the main gear 12. The main shaft 16 is connected to an armature 22 provided inside the power generation component housing 2. The armature 22 can adopt a neodymium iron boron permanent magnet, and the stator winding is an H-class insulating enameled wire. When the internal gear ring 13 drives the rotating block 14, the main gear 12 and the main shaft 16 to rotate, electricity can be generated through the armature 22 of the power generation component. Wires connected to a storage battery, a circuit board, etc. are provided on the armature 22.

[0030] An annular pull rope groove 17 is provided on the outer surface of the internal gear ring 13. A pull rope 18 is wound in the pull rope groove 17. The pull rope 18 is woven with aramid fiber, and the tensile strength is ≥2000 MPa, and the surface is coated with a polyurethane waterproof layer. The end of the pull rope 18 penetrates out of the outside of the power generation component housing 2 and is connected to a pull ring 19. By pulling the pull rope 18 through the pull ring 19, the internal gear ring 13 can be rotated on the fixed shaft 35, thereby driving the rotating block 14, the main gear 12 and the main shaft 16 to rotate.

[0031] An annular groove 20 is formed at the center of the surface on one side of the internal gear ring 13 away from the rotating block 14. A first coil spring 21 is installed in the annular groove 20. Coil spring grooves corresponding to both ends of the first coil spring 21 are respectively provided on the inner side of the annular groove 20 and the side surface of the fixed shaft. When the internal gear ring 13 is driven to rotate by the pull rope 18, the first coil spring 21 deforms and stores energy. After the pull rope 18 is released, the first coil spring 21 releases the stored energy to drive the internal gear ring 13 to rotate in the reverse direction, and winds the pull rope 18 into the pull rope groove 17. The pre-tightening force of the first coil spring 21 is set to 1.2 times the maximum torque of the internal gear ring 13 to prevent overload failure.

[0032] Specifically: When the pull rope 18 is pulled, the internal gear ring 13 rotates forward, and at the same time, the first coil spring 21 deforms. At this time, its rotation direction is opposite to the orientation of the pawl 15, and the pawl 15 is not pressed, so it can protrude from the pawl groove and engage with the internal tooth groove in the internal gear ring 13. The rotating block 14 rotates forward with the internal gear ring 13, and at the same time drives the main gear 12 and the main shaft 16 to rotate, and the armature 22 generates electricity; when the pull rope 18 is released, the first coil spring 21 is not affected by external force, and drives the internal gear ring 13 to rotate in the reverse direction during the process of restoring its original state. At this time, the rotation direction of the internal gear ring 13 is the same as the orientation of the pawl 15. When rotating, the pawl 15 is continuously pressed to contract back into the pawl groove. At this time, the rotating block 14, the main gear 12, the main shaft 16, etc. can continue to rotate forward under the action of inertia and will not rotate in the direction of the internal gear ring 13, ensuring the stability of power generation. By continuously pulling and releasing the pull rope 18, manual power generation can be carried out to store energy or supply power to lighting equipment, etc. The operation is simple and the use is convenient. When the power is insufficient, it can supply power to the lighting equipment to maintain good lighting, which is convenient for underground work.

[0033] The movable gear 8 that rotates and can slide on the ball screw 4 meshes with the main gear 12. When the main gear 12 drives the main shaft 16 to rotate and generate electricity, it can drive the movable gear 8 to rotate, and then drive the ball screw 4 to rotate, so that the movable sliding cleaning brush 5 cleans the surface of the lamp shade 3.

[0034] Specifically, a number of clamping blocks 9 are evenly arranged on the outer side surface of a section of the ball screw 4 located inside the power generation component housing 2. Corresponding clamping slots are evenly formed on the side surface of the movable gear 8. The movable gear 8 can be connected to the ball screw 4 through the clamping slots, so that the movable gear 8 is engaged with the ball screw 4, and the movable gear 8 drives the ball screw 4 to rotate when rotating.

[0035] Preferred technical solution: The movable gear 8 includes a gear portion and a frustum portion. The card slot is provided on the side surface of the gear portion, and the frustum portion is provided on the side of the gear portion away from the card slot. Inside the power generation assembly housing 2, a sliding block 25 is slidably provided in the height direction. A pressing block 24 is provided on the upper surface of the sliding block 25, and the pressing block 24 penetrates through the upper surface of the power generation assembly housing 2, facilitating the staff to press down the sliding block 25 through the pressing block 24. A curved surface matching the frustum portion is provided on the lower side of the sliding block 25. When the surface of the lamp cover 3 does not need to be cleaned, the pressing block 24 is not pressed downward, and the card slot of the movable gear 8 is not engaged with the clamping block 9. While the power generation assembly generates electricity, it will not drive the sliding cleaning brush 5 to move for cleaning. When the surface of the lamp cover 3 needs to be cleaned, the staff presses the pressing block 24 to move the sliding block 25 downward. When the sliding block 25 slides downward, the curved surface presses the frustum portion downward to move the movable gear 8 towards the clamping block 9, so that the card slot of the movable gear 8 is engaged with the clamping block 9. The movable gear 8 also meshes with the main gear 12. At this time, while the power generation assembly generates electricity, it can drive the movable gear 8 and the ball screw 4 to rotate, thereby driving the sliding cleaning brush 5 to move for cleaning. While cleaning the surface of the lamp cover 3, the power generation assembly can generate electricity and store energy, extending the battery life of the lighting device.

[0036] Optionally, the gear portion of the movable gear 8 is relatively long, so that the gear portion is always meshed with the main gear 12 during the movement process.

[0037] Preferred technical solution: A fixing plate is provided on the side surface of the sliding block 25, and a first fixing seat 27 corresponding to the fixing plate is provided inside the power generation assembly housing 2. A second spring 26 is provided between the first fixing seat 27 and the fixing plate. The second spring 26 makes the sliding block 25 reset to the position when it is not pressed, so that the movable gear 8 can be disengaged from the clamping block 9 and no longer drive the ball screw 4 to rotate, facilitating the reverse rotation of the ball screw 4 to reset the sliding cleaning brush 5 or clean the surface of the lamp cover 3 in the reverse direction.

[0038] Inside the upper side of the main body housing 1, a rotating rod 28 is rotatably provided through a fixed shaft. One end of the rotating rod 28 penetrates into the inside of the power generation assembly housing 2 and is connected to the upper inclined block 34. A lower inclined block 33 corresponding to the upper inclined block 34 is fixedly provided on the side surface of the sliding block 25. An inclined surface portion is provided on the upper side of the upper inclined block 34, and an inclined surface portion is provided on the lower side of the lower inclined block 33. When the sliding block 25 moves downward, the inclined surface portion of the lower inclined block 33 contacts and rubs against the inclined surface portion of the upper inclined block 34, which can make the upper inclined block 34 move downward. The whole rotating rod 28 deflects downward in the direction of the upper inclined block 34. The upper inclined block 34 and the lower inclined block 33 are staggered from each other. Then the rotating rod 28 resets, and the plane on the lower side of the upper inclined block 34 catches the plane on the upper side of the lower inclined block 33, fixing the sliding block 25 on the lower side, so that the movable gear 8 is fixed at the position engaged with the clamping block 9, ensuring the stability of the cleaning process.

[0039] A fourth spring 32 is provided between the lower surface of the end of the rotating rod 28 near the upper inclined block 34 and the first fixing seat 27; a third spring 30 is provided between the lower surface of the other end of the rotating rod 28 and the second fixing seat 31. The second fixing seat 31 is arranged on the inner surface of the main body housing 1. When the rotating rod 28 is not subject to external force, it is in a horizontal state under the action of the third spring 30 and the fourth spring 32. The third spring 30 and the fourth spring 32 are used to reset the rotating rod 28 to the horizontal state, so as to fix the sliding block 25 in the lower position or the upper position, etc.

[0040] In a preferred technical solution, a moving frame is fixedly arranged on the upper surface of the sliding cleaning brush 5. The moving frame is sleeved on the outside of the rotating rod 28. An inclined surface block 29 is arranged at one end of the rotating rod 28 far from the upper inclined block 34. The inclined surface arranged on the upper side of the inclined surface block 29 is inclined upward in the direction away from the upper inclined block 34. The third spring 30 is arranged on the lower side of the inclined surface block 29. When the sliding cleaning brush 5 moves, it drives the moving frame to move. When the moving frame moves on the outside of the rotating rod 28, it does not contact or slightly contacts it, without affecting its horizontal state and the rotation and reset of the rotating rod 28 during the downward pressing of the sliding block 25, etc.; when the moving frame moves to the inclined surface block 29, the inner surface thereof contacts the inclined surface of the inclined surface block 29, so that the whole rotating rod 28 deflects downward at the end far from the upper inclined block 34, and one end of the upper inclined block 34 deflects upward, no longer pressing the lower inclined block 33. The sliding block 25 moves upward and resets under the action of the second spring 26, no longer pressing the conical part of the movable gear 8, and the ball screw 4 no longer rotates following it, facilitating the sliding cleaning brush 5 to reset to its original position.

[0041] In a further preferred technical solution, a fixing ring 10 is fixedly arranged on a section of the ball screw 4 located inside the power generation component housing 2. A circular groove communicating with the card slot is formed inside the movable gear 8. A first spring 11 is arranged between the inner surface of the circular groove and the fixing ring 10. The first spring 11 can push the movable gear 8 away from the card block 9, so that it is no longer linked with the ball screw 4.

[0042] Furthermore, at least one end of the two ends of the ball screw 4 is provided with a second torsion spring. The second torsion spring is arranged inside the torsion spring cylinder 23. The torsion spring cylinder 23 is arranged inside the main body housing 1 or the power generation component housing 2. When the ball screw 4 rotates following the movable gear 8, it drives the second torsion spring to rotate and store energy; after the movable gear 8 is separated from the card block 9, the ball screw 4 no longer rotates following it. At this time, the moving frame and the sliding cleaning brush 5 also move to the other end of the lamp cover 3. The second torsion spring releases the stored energy, drives the ball screw 4 to rotate in the reverse direction, and the ball screw 4 drives the sliding cleaning brush 5 back to its original position and cleans the surface of the lamp cover 3 in the reverse direction.

[0043] Optional technical solution: A slider 6 is provided at the bottom end of the sliding cleaning brush 5, and a slider groove 7 corresponding to the slider 6 is opened on the inner side of the main body housing 1 below the lamp shade 3. When the sliding cleaning brush 5 moves following the nut, the slider 6 on its lower side slides in the slider groove 7, improving the stability of the movement of the sliding cleaning brush 5.

[0044] Further optionally, the slider groove 7 communicates with the outer side of the lower surface of the main body housing 1, and the lower side of the slider groove 7 is a through groove. When cleaning the surface of the lamp shade 3, the dust and other attachments removed can fall from the slider groove 7 to the outside, rather than accumulating on the lower side of the lamp shade 3 or in the slider groove 7.

[0045] Furthermore, a graphite lubricating strip is embedded in the slider groove 7 to reduce the sliding resistance of the slider 6 and avoid jamming.

[0046] Optionally, a dust-proof silica gel sleeve is sleeved on the outer sides of the main body housing 1 and the power generation component housing 2 for dust-proofing the whole device; protrusions corresponding to the pressing block 24, the lighting switch, etc. are provided on the dust-proof silica gel sleeve to dust-proof these positions. Both the main body housing 1 and the power generation component housing 2 are made of explosion-proof materials and internally provided with explosion-proof isolation layers (such as ceramic fiber filling layers) to isolate the circuit from the external flammable gas. The overall protection level of the device is IP68, and it can work continuously in an environment where the dust concentration > 100mg / m 3 environment.

[0047] Optionally, the power generation component further includes an acceleration gear set 36. The acceleration gear set 36 meshes with the main gear 12, and the end gear of the acceleration gear set 36 is provided on the main shaft 16. The main shaft 16 can be accelerated through the acceleration gear set 36, increasing its rotation speed and improving the power generation efficiency. Each gear, gear set, etc. in this application is preferably made of engineering plastics (such as POM polyoxymethylene), which is wear-resistant and self-lubricating, reducing the frictional loss of the gears.

Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
