Description

Technical Field

[0001] The invention belongs to the technical field of cleaning walkway lamp covers, and in particular relates to a walkway lamp cover cleaning device. Background Art

[0002] Trail lights are lighting devices installed on both sides of the walkway, combining functionality and decoration. Their lampshades are mostly made of glass, PC or metal. The lampposts are variously shaped, including cylindrical and square columns, to suit different scenarios. The light source is mainly LED, which is energy-saving and has a long lifespan. They are widely used on trails in parks, residential areas, scenic spots, etc. They not only provide nighttime lighting, but also beautify the environment and enhance the spatial atmosphere through lighting design. Some have intelligent sensing and self-cleaning functions, enhancing practicality and convenience. The existing method of cleaning trail lights mostly uses a cleaning vehicle to spray water directly onto the surface of the trail lights for flushing. However, this flushing method is difficult to clean the dust in the gaps on the surface of the trail lights, and the traditional cleaning method does not have the function of automatically wiping water after cleaning, so manual wiping will be very troublesome. If not wiped, water evaporation will leave water marks and scale, which cannot keep the surface of the lamp body smooth and beautiful. Summary of the Invention

[0003] The object of the present invention is to provide a device for cleaning the cover of a walkway lamp, which has the advantage of automatically cleaning and drying the walkway lamp.

[0004] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a walkway lamp cover cleaning device, comprising a base frame, a fixing plate welded on the upper end of one side of the base frame, the fixing plate and the base frame surface are jointly welded with two sliding rods, the surfaces of the two slide rods are jointly slidably connected with a slide plate, the surface of the slide plate is provided with a cleaning assembly, the surface of the cleaning assembly is provided with a wiping assembly, the surface of the cleaning assembly is provided with a connecting plate, the connecting plate and the cleaning assembly are jointly provided with a first reciprocating screw rod, one end of the first reciprocating screw rod is fixedly connected to the motor through a coupling, and the motor is detachably connected to the base frame, the upper end of the base frame is detachably connected to a water tank, a water pump is bolted inside the water tank, a connecting pipe is jointly provided between the output end of the water pump and the cleaning assembly, a water inlet is welded on the upper end of the water tank, rollers are rotatably connected at the four corners of the lower surface of the base frame, and a push handle is welded in the middle of one side of the base frame.

[0005] When the above technical solution is adopted, it is necessary to use the sliding rod to slide the slide plate and the cleaning assembly. When the cleaning assembly is slid to a certain height, the cleaning assembly can be put on the surface of the trail lamp, and then the water pump uses the connecting pipe to transport the water inside the water tank to the inside of the cleaning assembly. The transported water will flow downward along the top of the trail lamp, thereby wetting the trail lamp. The connecting pipe can adjust the length of its extension into the inside of the cleaning assembly according to the height of the trail lamp, so that the connecting pipe can discharge water at a position close to the top of the trail lamp to prevent water from splashing and wasting. When the trail lamp is wetted, start the motor, and the motor will use the first reciprocating screw to drive the cleaning assembly to move and clean the surface of the trail lamp. When it cleans the upper end of the trail lamp, the cleaning structure will move downward. During the downward movement, the wiping assembly will wipe the water on the surface of the trail lamp, and the inside of the drying assembly also has the function of squeezing out the water inside the wiping structure to prevent the wiping structure from inhaling too much water and affecting the wiping effect.

[0006] The present invention is further configured as follows: the cleaning assembly includes a protective shell, the protective shell is welded to the surface of the skateboard and the connecting plate, a threaded groove is opened on the inner wall of the protective shell, a threaded hole is opened inside the threaded groove, and push rods are welded at both ends of the protective shell.

[0007] By adopting the above technical solution, the threaded groove is used for the sliding of the extrusion column, the threaded hole is used for the sliding of the extrusion rod, the protective shell is used to prevent random splashing of water, and the push rod is used to push the moving plate and the cleaning brush to move.

[0008] The present invention is further configured as follows: a screw plate is threadedly connected to the surface of the first reciprocating screw rod, the screw plate is slidingly connected to the protective shell, a lifting ring is welded to one end of the screw plate, and the lifting ring is arranged inside the protective shell, and the surface of the lifting ring is rotatably connected to a rotating shell.

[0009] By adopting the above technical solution, the screw plate can be driven to move by the first reciprocating screw rod. When the extrusion column is squeezed by the thread groove, the rotating shell will be driven to rotate on the surface of the lifting ring along the trajectory of the thread groove.

[0010] The present invention is further configured as follows: extrusion columns are welded on both sides of the rotating shell surface, and the extrusion columns are slidingly connected to the thread grooves; a limiting shell is welded on the inner wall of the rotating shell; and four groups of limiting plates are welded on the inner wall of the limiting shell.

[0011] With the above technical solution, the limiting plate is used to limit the movement of the movable plate.

[0012] The present invention is further configured as follows: the four groups of limit plates are slidably connected to a movable plate, two positioning holes are provided on the four sides of the rotating shell surface, a cleaning brush is inserted into the movable plate, and four groups of through holes are provided on the cleaning brush and the surface of the movable plate.

[0013] According to the above technical solution, the cleaning brush is used to clean the surface of the trail light, the cleaning brush is inserted into the inside of the movable plate, and the positioning hole is used to position the positioning rod.

[0014] The present invention is further configured as follows: a positioning rod is slidably connected to the two through holes corresponding to the surface of the cleaning brush and the movable plate; a spring is sleeved on the surface of the positioning rod, and both ends of the spring are respectively connected between the positioning rod and the cleaning brush through spring fixing parts; the positioning rod and the positioning hole are detachably connected.

[0015] With the above technical solution, since the surface of the positioning rod is inclined and the tempered material is relatively smooth, when the movable plate is moved, the positioning rod will be squeezed and retracted. When the movable plate moves to the appropriate position, the spring will pull the positioning rod through the through hole and position it inside the new positioning hole, thereby fixing the cleaning brush.

[0016] The present invention is further configured as follows: the wiping assembly includes a rotating column, and there are eight rotating columns, the eight rotating columns are all rotatably connected to the inside of the rotating shell, a second torsion spring is sleeved on the surface of the rotating column, and a movable shell is rotatably connected between the corresponding two rotating columns.

[0017] By adopting the above technical solution, the movable shell can be rotated by the rotating column, and the second torsion spring is used to drive the movable shell to rotate and reset after rotation.

[0018] The present invention is further configured as follows: a second reciprocating screw is rotatably connected to one end of the movable shell, a movable frame is threadedly connected to the surface of the second reciprocating screw, and the movable frame and the movable shell are slidingly connected, three groups of extrusion wheels are rotatably connected to the inside of the movable frame, a circular gear is welded to one end of the connecting column, and two groups of arc brushes are bolted to both ends of the movable frame, and the two groups of arc brushes are fitted and sleeved on the surface of the second reciprocating screw.

[0019] With the above technical solution, when the circular gear is driven to rotate by the face gear, the second reciprocating screw is used to drive the movable frame and the extrusion wheel to move back and forth, so that the water-absorbing sponge is squeezed by the extrusion wheel to release water.

[0020] The present invention is further configured as follows: a water-absorbing sponge is detachably connected to the interior of the movable shell; the movable shell and the water-absorbing sponge are threadedly connected with two screws; and the water-absorbing sponge is movably connected to the extrusion wheel.

[0021] With the above technical solution, screws are used to install the absorbent sponge inside the movable shell.

[0022] The present invention is further configured as follows: a rotating shaft is sleeved on the surface of the rotating shell, and the rotating shaft and the rotating shell are fixedly connected; a face gear is fixedly sleeved on the lower surface of the rotating shaft, and the face gear and the circular gear are meshed and connected; an extrusion rod is welded on one side of the face gear, and the extrusion rod is slidably connected to the threaded hole.

[0023] By adopting the above technical solution, when the face gear follows the movement of the rotating shell, the extrusion rod will move linearly in the straight part inside the threaded hole. When the extrusion rod moves to the curved part at the lower end of the threaded hole, it will drive the face gear to rotate using the rotating shaft. The rotating shaft is a structure similar to that of a bearing. When the inner ring and the outer ring are fixedly connected to the rotating shell and the face gear respectively, they can still rotate because the bearing itself has the function of rotation. The rotation of the face gear will drive the circular gear to rotate.

[0024] In summary, the present invention has the following beneficial effects: The water inlet is used to fill water into the water tank, and pushing the push handle can make the device move with the rollers. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 3: Based on Example 2, Figure 3-5 , Figure 4-5 、 Figure 12-15The wiping assembly 8 includes a rotating column 806, and there are eight rotating columns 806. The eight rotating columns 806 are all rotatably connected to the inside of the rotating shell 906. A second torsion spring 807 is provided on the surface of the rotating column 806, and a movable shell 808 is connected to the two corresponding rotating columns 806 for common rotation; one end of the movable shell 808 is rotatably connected to the second reciprocating screw rod 805, and the surface of the second reciprocating screw rod 805 is threadedly connected to the movable frame 803, and the movable frame 803 and the movable shell 808 are slidingly connected. Three sets of extrusion wheels 813 are rotatably connected to the inside of the movable frame 803, and a circular gear 804 is welded to one end of the connecting column 805. Two sets of arc brushes are bolted at both ends of the movable frame 803. 814, two sets of arc-shaped brushes 814 are fitted and sleeved on the surface of the second reciprocating screw rod 805; the movable shell 808 is detachably connected to the inside of the absorbent sponge 809, and the movable shell 808 and the absorbent sponge 809 are commonly threadedly connected with two screws 811, and the absorbent sponge 809 is movably connected to the extrusion wheel 813; a rotating shaft 802 is sleeved on the surface of the rotating shell 906, and the rotating shaft 802 is fixedly connected to the rotating shell 906, and a face gear 801 is fixedly sleeved on the lower surface of the rotating shaft 802, and the face gear 801 is meshed with the circular gear 804, and an extrusion rod 810 is welded on one side of the face gear 801, and the extrusion rod 810 is slidably connected to the threaded hole 903.

[0032] Brief description of the usage process: When cleaning the surface of the trail light, start the motor 2, and the motor 2 will drive the screw plate 916 to move upward on the surface of the first reciprocating screw 3, thereby driving the lifting ring 905 to move upward. During the movement, since the extrusion column 915 is arranged inside the thread groove 902, the extrusion column 915 will rotate along the trajectory of the thread groove 902, thereby driving the rotating shell 906 to rotate. The rotation of the rotating shell 906 will drive the cleaning brush 910 to rotate and clean the surface of the trail light (the cleaning brush 910 has been widened to prevent omissions in the cleaning of the trail light surface during rotation). When the rotating shell 906 moves to the top of the protective shell 901, the cleaning brush 910 will be pushed by the top rod 904. Since the moving plate 909 is engaged with the cleaning brush 910, the cleaning brush 910 will pass through the limit plate after being subjected to force. The cooperation between 908 and the limiting shell 907 drives the movable plate 909 to move downward, preventing the movable plate 909 from rotating and falling off from the limiting shell 907 during movement. As the movable plate 909 moves downward, the positioning rod 912 is subjected to force. Since the surface of the positioning rod 912 is inclined and made of tempered material, the surface is relatively smooth. Therefore, when the movable plate 909 is pressed by the top rod 904, the positioning rod 912 located in the upper positioning hole 911 is squeezed and disengaged, so that the spring 913 drives the positioning rod 912 to be stuck in the bottom positioning hole 911, thereby fixing the cleaning brush 910. The cleaning brush 910 is inserted into the inside of the movable plate 909 for easy disassembly and assembly. Since the movable plate 909 moves downward at this time, it will not limit the absorbent cotton 809, so the second torsion spring 807 will drive the absorbent cotton 809 to unfold ( Figure 5 Display), after unfolding, the absorbent sponge 809 will follow the running track of the rotating shell 906 to absorb water from the trail light. The absorbent sponge 809 is fixed by screws 811 and can be removed and replaced. When the rotating shell 906 moves upward, the cleaning brush 910 is in a state of blocking the absorbent sponge 809 and preventing the absorbent sponge 809 from unfolding (as shown in FIG. Figure 4As shown), the water-absorbing sponge 809 is made of high-density extruded foam board material, which has a certain hardness and will not be easily torn. When the lifting ring 905 moves down from the upper end, the rotating shell 906 will continue to rotate. At this time, the water pump 12 is turned off, so the rotating shell 906 drives the cleaning brush 910 to clean the surface of the trail light again. At the same time, it will cause the water-absorbing sponge 809 to rotate and wipe the water on the surface of the trail light. When the lifting ring 905 moves at the upper end, since the extrusion rod 810 is inside the threaded hole 903 and the extrusion column 915 slides synchronously inside the threaded groove 902, the extrusion rod 810 does not drive the face gear 801 to rotate. When the lifting ring 905 moves to the lower end position of the protective shell 901, since the threaded hole 903 is converted into a straight state, the extrusion rod 810 will stop threading movement. Since the extrusion column 915 is still The rotating shell 906 is driven to rotate by the rotating shaft 802, so that the circular gear 804 that rotates with the rotating shell 906 rotates on the surface of the face gear 801. The rotation of the circular gear 804 drives the second reciprocating screw rod 805 to rotate, and the second reciprocating screw rod 805 drives the movable frame 803 to move back and forth. During the movement of the movable frame 803, the arc-shaped brush 814 cleans the surface of the second reciprocating screw rod 805 to prevent sewage from affecting the movement of the movable frame 803 on the surface of the second reciprocating screw rod 805. Because the arc-shaped brush 814 is a circle composed of two semicircles, it is easy to replace after being damaged. In addition, the movable frame 803 drives the extruding wheel 813 to roll on the surface of the water-absorbing sponge 809, thereby squeezing out the water inside the water-absorbing sponge 809 to prevent the water inside the water-absorbing sponge 809 from being absorbed too much and affecting its use (threaded hole 903 The length of the bottom vertical part is adapted to the transmission ratio of the face gear 801 and the circular gear 804, and the gear ratio of the face gear 801 to the circular gear 804, and the connection relationship between the circular gear 804 and the second reciprocating screw 805 satisfies the following conditions: when the extrusion rod 810 moves from the top of the bottom vertical part of the threaded hole 903 to the end, the circular gear 804 drives the second reciprocating screw 805 to rotate the number of circles through the face gear 801, just enough to make the movable frame 803 complete a reciprocating motion along the second reciprocating screw 805, that is, move from the initial position to the farthest position and then return to the initial position, and the extrusion wheel 813 moves along with the movable frame 803. Synchronously reset to the initial position), when the lifting ring 905 moves to the bottom of the protective shell 901, the top rod 904 at the bottom will push the movable plate 909 and the cleaning brush 910 to move upward. During the upward movement, the cleaning brush 910 will push the movable shell 808 upward, so that the movable shell 808 can be flipped upward by the rotating column 806. Finally, the four groups of movable shells 808 are flipped to the gaps on the four sides of the rotating shell 906. At this time, the positioning rod 912 will be positioned inside the positioning hole 911 at the upper end. During the flipping process of the movable shell 808, the circular gear 804 will be out of contact with the face gear 801.
