Description

Technical Field

[0001] The present invention relates to the field of municipal cleaning equipment, in particular to an environmentally friendly streetlight pole cleaning device. Background Art

[0002] Street lighting is essential infrastructure for nighttime road safety. However, light poles, long located on the sides of highways, are subject to erosion from the elements, including wind, sand, rain, dew, and smog. Water, particularly after rain or snow, accumulates on the roads, splashing onto the poles from vehicle tires and adhering to their surfaces. This impacts the poles' aesthetic appeal, polluting them and negatively impacting public expectations for environmental friendliness and aesthetics. Traditionally, light pole cleaning is performed manually by cleaning staff. This manual cleaning process is labor-intensive, costly, and poses safety risks to cleaning staff, as well as the potential for secondary pollution to the road and pedestrians.

[0003] In recent years, street light pole cleaning devices have also appeared on the market. Patent CN215236255U discloses a street light pole cleaning device. According to the contents recorded in the specification and the drawings of the specification, the device can only clean the street light pole located above the cleaning carriage, and cannot clean the position below the carriage. Moreover, the roller brushes of the device are exposed to the outside. After the cleaning water is sprayed out, it is directly thrown out by the roller brush. The wastewater easily pollutes the area outside the street light pole and wastes water resources. Moreover, the street light pole cleaning device of the patent can only be used for cleaning vertical lamp poles. In the actual cleaning process, some tilted street light poles are often encountered. The device cannot be adjusted with the tilted street light poles during the cleaning process, so it cannot achieve a good cleaning effect for tilted street light poles. Summary of the Invention

DETAILED DESCRIPTION

[0038] The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0039] In this embodiment, in order to facilitate the description of the specific structural position, as shown in FIG. Figure 1As shown, the side of the lifting module where the cleaning tank is set is the right side, and the other side is the left side. As Figure 3 shown, the two cleaning tanks are arranged front and back.

[0040] As Figures 1 to 4 shown, an environment-friendly street lamp pole cleaning device mainly consists of a base 1, a lifting module 2, a cleaning module 5, etc. The base 1 is two parallel vertical plates 101, and the two vertical plates 101 are connected and fixed by connecting plates 102 arranged at intervals along the length direction of the vertical plates 101, and the connecting plates 102 are connected and fixed to the carriage bottom plate by bolts.

[0041] A fixing frame 3 is arranged at the left end of the base 1 (the end located inside the carriage is the left), and a driving mechanism is installed on the fixing frame 3. The driving mechanism is mainly a driving motor 9, and a coaxial rotating driving sprocket 10 is installed on the output shaft of the driving motor 9.

[0042] A slideway 17 is respectively arranged on the inner side of each vertical plate 101. A reinforcing plate 8 is fixedly welded between the two slideways 17, and the reinforcing plate 8 is arranged at intervals along the length direction of the slideways 17 between the two slideways 17.

[0043] A number of slideway rollers 16 cooperating with the slideways 17 are respectively installed at intervals on the inner side of each vertical plate 101.

[0044] In this embodiment, the slideway 17 is made of a "U"-shaped section steel. The slideway 17 is buckled on the inner side of the vertical plate 101 and the inner wall of the slideway 17 is in rolling connection with the slideway rollers 16.

[0045] Mounting plates 29 are respectively arranged at both ends of each vertical plate 101. The mounting plates 29 are placed on the upper part of the vertical plates 101. A sprocket 14 is installed on the inner side of the mounting plates 29. The two sprockets 14 on the same vertical plate 101 are connected by a second transmission chain 15. Each slideway 17 is respectively connected to the corresponding second transmission chain 15 through a connecting block 37.

[0046] The transmission mechanism mainly consists of a transmission shaft 13, a transmission sprocket 12, etc. The transmission shaft 13 is installed between the two sprockets 14 at one end inside the carriage, and the two sprockets 14 rotate coaxially with the transmission shaft 13. The transmission sprocket 12 is fixedly installed in the middle of the transmission shaft 13, and the transmission sprocket 12 is connected to the driving sprocket 10 by a first transmission chain 11.

[0047] In this embodiment, the driving motor 9 drives the transmission sprocket 12 to rotate through a chain transmission, thereby rotating the transmission shaft 13, and the transmission shaft 13 drives the sprockets 14 at both ends of the base 1 that rotate coaxially with it to rotate. The two sprockets 14 on the transmission shaft 13 respectively drive the sprockets 14 at the other end of their respective vertical plates 101 to rotate through the transmission chain 2 15, thereby moving the slide 17 along the slide roller 16, so that the slide 17 can slide toward the inside or outside of the compartment (i.e., slide left and right).

[0048] Lifting module 2 primarily consists of a lifting arm assembly and a hoisting mechanism. Each lifting arm assembly comprises a first lifting arm assembly, a second lifting arm assembly, and a fixed platform 18 atop the first and second lifting arm assemblies. The first and second lifting arm assemblies are symmetrical, each consisting of four layers of lifting arms. Each lifting arm assembly, from the outside inward, comprises arm 1 201, arm 2 202, arm 3 203, and arm 4 204.

[0049] like Figure 2 、 Figure 3 、 Figure 4 As shown, taking the first lifting arm group as an example, the lifting arm 1 201, the lifting arm 2 202, the lifting arm 3 203 and the lifting arm 4 204 are all made of C-shaped steel. The lower end of the lifting arm 1 201 is fixedly connected to the slide 17. On the left side of the first lifting arm group, a fixing block 1 21 is provided in the middle of the lifting arm 1 201, a fixing block 24 is provided at the bottom of the lifting arm 3 203, and a lifting sprocket 22 is provided on the top of the lifting arm 202. One end of the lifting chain 1 23 is fixed on the fixing block 1 21, and the other end passes around the lifting sprocket 1 22 and is fixed on the fixing block 1 On the fixed block 24; on the right side of the first lifting arm group, a fixed block 3 25 is provided in the middle of the lifting arm 202, a fixed block 4 26 is provided at the bottom of the lifting arm 4 204, and a lifting sprocket 2 27 is provided on the top of the lifting arm 3 203. One end of the lifting chain 2 28 is fixed on the fixed block 3 25, and the other end is fixed on the fixed block 4 26 after passing through the lifting sprocket 2 27; the lifting arm 1 201, lifting arm 2 202, lifting arm 3 203 and lifting arm 4 204 in the second lifting arm group have the same connection principle as the four-layer lifting arm in the first lifting arm group.

[0050] In this embodiment, between the first lifting arm group and the second lifting arm group, the upper and lower ends of the two lifting arms 1 201, the upper and lower ends of the two lifting arms 202, the upper and lower ends of the two lifting arms 3 203, and the upper and lower ends of the two lifting arms 4 204 are respectively connected by strip steel plates, so that the two symmetrical lifting arms form a rectangular frame structure.

[0051] The left sides of the two lifting arms 202 are connected by a transverse connecting rod 20. The middle part of the transverse connecting rod 20 is connected to the piston rod of the main hydraulic cylinder 19. The piston rod of the main hydraulic cylinder 19 rises to push the transverse connecting rod 20. The transverse connecting rod 20 drives the two lifting arms 202 to rise. The lifting arm 202 drives the lifting arm 3 203 and the lifting arm 4 204 to rise through chain transmission, thereby realizing the rise of the two lifting arm groups.

[0052] like Figure 13 As shown, in this embodiment, the lifting arms of the two lifting arm groups are all made of C-shaped steel. To ensure that the second lifting arm 202, the third lifting arm 203, and the fourth lifting arm 204 of each lifting arm group can be raised and lowered smoothly, auxiliary lifting wheels 206 are installed between adjacent lifting arms. In this embodiment, a set of auxiliary lifting wheels 206 is installed on the side of the second lifting arm 202 close to the first lifting arm 201 (each set of auxiliary lifting wheels has at least two, installed at the bottom of the second lifting arm 202, to ensure that the uppermost auxiliary lifting wheel 206 remains in the slot of the lifting arm when the lifting arm reaches the top). The auxiliary lifting wheels 206 are positioned within the inner groove of the first lifting arm 201. Another set of auxiliary lifting wheels 206 is mounted on the side of the third lifting arm 203 near the second lifting arm 202 (installed in the same manner as on the second lifting arm 202), positioned within the inner groove of the second lifting arm 202. Another set of auxiliary lifting wheels 206 is mounted on the side of the fourth lifting arm 204 near the third lifting arm 203 (installed in the same manner as on the second lifting arm 202), positioned within the inner groove of the third lifting arm 203. During the raising and lowering of the two lifting arm groups, the adjacent lifting arms guide the auxiliary lifting wheels for upward and downward movement, ensuring vertical movement of the arms. The two arms are raised and lowered by the auxiliary lifting wheels 206 between them, reducing friction between the two arms and ensuring smooth operation of the arm groups.

[0053] like Figure 1 、 Figure 2 、 Figure 5 As shown, in this embodiment, the fixed platform 18 is placed between the two lifting arms 204, and the left and right ends of the fixed platform 18 are respectively welded and fixed to the top of the lifting arm 204 through the fixed platform reinforcement plate 1801, and the lifting mechanism is placed on the fixed platform 18.

[0054] like Figure 11 、 Figure 12As shown, a rolling plate 32 is further provided between the two lifting arms four 204, and rolling wheels 3201 are installed at the upper and lower positions on both sides of the rolling plate 32. The rolling wheels 3201 on both sides of the rolling plate 32 are respectively placed in the inner grooves of the lifting arms four 204 on their respective sides (since the lifting arms four are made of C-shaped steel, the inner grooves of the lifting arms four serve as tracks for the rolling wheels 3201), and are rollingly connected to the inner groove walls of the lifting arms four 204.

[0055] The rolling plate 32 in this embodiment is composed of a vertical plate 3202 and a horizontal plate 3203, and the horizontal plate 3203 is horizontally placed on the top of the vertical plate 3202; the front and rear sides of the vertical plate 3202 of the rolling plate 32 are respectively installed with rolling wheels 3201, and the horizontal plate 3203 of the rolling plate 32 is connected to the horizontal adjustment mechanism 4 through a telescopic sleeve 33.

[0056] The telescopic sleeve 33 is mainly composed of an inner tube 3301 and an outer tube 3302. The inner tube 3301 is inserted into the outer tube 3302.

The outer side of the inner tube 3301 is connected to the vertical plate 3202 via a stiffening plate; the outer tube 3302 is fixedly connected to the transverse adjustment mechanism 4 (connected to the fixed plate 402 of the transverse adjustment mechanism 4 described below).

[0057] The lifting mechanism includes an electric hoist 205 , a pulley 1 34 and a pulley 2 35 . The electric hoist 205 and the pulley 1 34 are installed on the fixed platform 18 , and the pulley 2 35 is connected to the lateral adjustment mechanism 4 .

[0058] The transverse adjustment mechanism 4 is placed below the transverse plate 3203. The transverse adjustment mechanism 4 is mainly composed of a hanging plate 401, a fixed plate 402 and a transverse adjustment frame. There are two hanging plates 401 symmetrically arranged, and the hanging plate 401 is placed on the left side of the fixed plate 402. Pulley 2 35 is installed between the two hanging plates 401. The wire rope of the electric hoist 205 passes through pulley 1 34 and pulley 2 35 in turn and is fixed on the fixed platform 18.

[0059] The horizontal adjustment frame is placed on the right side of the fixed plate 402. The horizontal adjustment frame mainly consists of two oppositely arranged vertical plates 403 and two horizontal adjustment plates 404 placed between the vertical plates 403. The upper and lower ends of the two vertical plates 403 are connected by horizontal plates 405 respectively.

[0060] Guide wheels 406 are respectively installed at the upper and lower ends of the fixed plate 402. The guide wheels 406 at the upper and lower ends of the fixed plate 402 are respectively placed between the fixed plate 402 and the horizontal plate 405. The guide wheels 406 at the upper and lower ends corresponding to the two vertical plates 403 are respectively provided with guide rails 407 that match them. The horizontal adjustment frame realizes relative rolling between the fixed plate 402 through the mutual cooperation between the guide wheels 406 and the guide rails 407.

[0061] like Figure 6 、 Figure 7 As shown, a one-way screw 408 and a two-way screw 409 are installed between the two horizontal plates 405 from top to bottom, and the two ends of the one-way screw 408 and the two-way screw 409 are respectively connected to the vertical plate 403 on the corresponding side through bearings, wherein a drive motor 1 410 is installed on the vertical plate 403 on the rear side, and the output end of the drive motor 1 410 is connected to the one-way screw 408, and a drive motor 2 411 is installed on the vertical plate 403 on the front side, and the output end of the drive motor 2 411 is connected to the two-way screw 409.

[0062] A screw nut 1 412 is provided on the one-way screw, and the screw nut 1 412 is welded and fixed to the right side wall of the fixed plate 402. The two-way screw 409 corresponds to two sections of reverse threads and is respectively provided with corresponding screw nuts 2 413. Each screw nut 2 413 is respectively welded to a horizontal adjustment plate 404.

[0063] A stop plate 414 is welded to the upper and lower ends of the corresponding transverse adjustment plate 404 between the two vertical plates 403. A guide clamping plate 415 is provided between each stop plate 414 and its corresponding transverse plate 405. Guide grooves are formed between the stop plates 414, the guide clamping plates 415, and the transverse plate 405, and the transverse adjustment plate 404 is positioned within the guide grooves. In this embodiment, the stop plates 414, the guide clamping plates 415, and the transverse plate 405 are connected to form a single unit via bolts running through them.

[0064] By controlling the forward and reverse rotation of the driving motor 1 410 , the entire structure on the fixed plate 402 can be moved forward and backward. By controlling the forward and reverse rotation of the driving motor 2 411 , the entire structure on the two horizontal adjustment plates 404 can be opened and closed.

[0065] The cleaning module 5 consists of two symmetrically arranged cleaning boxes 501. A connecting frame 502 is provided on the top plate of each cleaning box 501. A horizontal telescopic mechanism 6 is provided in each connecting frame 502. The cleaning box 501 is connected to the horizontal adjustment plate 404 through the horizontal telescopic mechanism 6.

[0066] like Figure 5 As shown, each horizontal telescopic mechanism 6 includes a fixed support arm 601, the left end of the fixed support arm 601 passes through the respective connecting frame 502, and is welded and fixed to the lateral adjustment plate 404 on the corresponding side, and an electric telescopic device is provided inside the fixed support arm 601. The electric telescopic device in this embodiment is an electric push rod 602, and the electric push rod 602 is also fixed on the lateral adjustment plate 404. The telescopic end of the electric push rod 602 is connected to the connecting frame 502 at the top of the cleaning box 501.

[0067] like Figure 10As shown, a sliding assembly is provided on the left side of the connecting frame 502 corresponding to the position of the fixed support arm 601. The sliding assembly mainly consists of a mounting frame 603 and an auxiliary telescopic roller 604. The mounting frame 603 is a square structure formed by welding four steel plates, as shown in FIG. Figure 10 As shown, auxiliary telescopic rollers 604 are respectively installed on the top, front side and rear side of the installation frame 603 corresponding to the fixed support arm 601 to ensure that the installation frame 603 and the fixed support arm 601 can slide relative to each other.

[0068] In this embodiment, in order to ensure that the horizontal telescopic mechanism 6 has sufficient supporting force for supporting the cleaning box 501, a telescopic support arm can be installed on the outside of the electric push rod 602, and the telescopic support arm is installed inside the fixed support arm 601, and the left end of the telescopic support arm is fixed to the telescopic end of the electric push rod 602. When the telescopic end of the electric push rod 602 is extended, it pushes the telescopic support arm to extend from the fixed support arm 601, thereby supporting the cleaning box 501.

[0069] Each cleaning box 501 is symmetrically provided with L-shaped partitions 503, and the roller brush 504 is placed between the two partitions 503. A cleaning motor 505 is installed on the top of each cleaning box 501, and the output end of the cleaning motor 505 and the central axis of the roller brush 504 are driven by a sprocket chain.

[0073] The two buffer limit mechanisms 7 are respectively the first buffer limit mechanism and the second buffer limit mechanism. In this embodiment, the first buffer limit mechanism and the second buffer limit mechanism are symmetrically arranged. The first mounting bracket 706 is installed on the top connecting frame 502 of the front cleaning box 501 corresponding to the first buffer limit mechanism. The first mounting bracket is also provided with an adjustment long hole 708. An adjustment bolt 707 is vertically welded on the connecting frame 502 corresponding to the first buffer mechanism. The adjustment bolt 707 passes through the adjustment long hole 708 and locks the first mounting bracket 706 through a double nut. The upper and lower heights and the front and rear positions of the first mounting bracket 706 can be adjusted through the double nut structure.

[0074] One end of the first mounting bracket 706 is provided with a counterclockwise rotation start limiter 709, and the other end of the first mounting bracket 706 is provided with a clockwise rotation stop limiter 710. A connecting rod 711 is also fixedly installed between the two telescopic rods 701 of the first buffer limit mechanism. The two ends of the connecting rod 711 are respectively welded and fixed to the telescopic rod 701 on their respective sides. A first collision column 712 and a second collision column 713 are fixedly installed on the connecting rod 711, and the second collision column 713 is longer than the first collision column 712. The first collision column 712 is corresponding to the counterclockwise rotation start limiter 709, and the second collision column 713 is corresponding to the clockwise rotation stop limiter 710.

[0075] A second mounting bracket 714 is installed on the top connecting frame 502 of the cleaning box 501 on the rear side corresponding to the second buffer limiting mechanism. The second mounting bracket 714 has a symmetrical structure with the first mounting bracket. An adjusting bolt 707 is vertically welded on the top of the connecting frame 502 corresponding to the second mounting bracket 714. An adjusting long hole 708 is also provided on the second mounting bracket. The adjusting bolt 707 passes through the adjusting long hole 708 and locks the second mounting bracket 714 through a double nut. The upper and lower heights and the front and rear positions of the second mounting bracket 714 can be adjusted through the double nut structure.

[0076] A clockwise rotation start limiter 715 is installed at one end of the second mounting bracket 714, and a counterclockwise rotation stop limiter 716 is installed at the other end of the second mounting bracket 714. A connecting rod 2 717 is also fixedly installed between the two telescopic rods 701 of the second buffer limit mechanism, and a third collision column 718 and a fourth collision column 719 are fixedly installed on the connecting rod 2 717, and the fourth collision column 719 is longer than the third collision column 718. The third collision column 718 is arranged corresponding to the clockwise rotation start limiter 715, and the fourth collision column 719 is arranged corresponding to the counterclockwise rotation stop limiter 716.

[0077] In this embodiment, the counterclockwise rotation start limiter 709 , the clockwise rotation stop limiter 710 , the clockwise rotation start limiter 715 , and the counterclockwise rotation stop limiter 716 are electrically connected to the driving motor 1 410 , respectively.

[0078] In this embodiment, in order to improve the overall stability of the cleaning device, hydraulic support legs 31 are installed on both sides of the lifting arm 201 through brackets 30. When the cleaning device is moved to the outside of the compartment for cleaning operations, the hydraulic support legs 31 are lowered to support the cleaning device as a whole.

[0079] When cleaning, the device works as follows:

[0080] The vehicle is controlled to stop at a suitable position near the street lamp pole to be cleaned, and the drive motor 9 is started. The drive motor 9 drives the drive shaft 13 to rotate through the chain transmission, and then the sprockets 14 at both ends of the drive shaft 13 rotate coaxially with the drive shaft 13. At the same time, the sprockets 14 at both ends of the drive shaft 13 respectively rotate the sprockets 14 on the same vertical plate 101 through their respective corresponding transmission chains 15. While the two sprockets 14 on the vertical plate 101 rotate, the slide 17 on the inner side of the vertical plate 101 is driven to the right (i.e., the outside of the car) through the connecting block 37 fixedly connected to the chain to move to the right side of the cleaning box 501 near the street lamp pole, and the hydraulic support legs 31 are started to support the ground to keep the lifting arm stable.

[0081] Then the drive motor 1 410 is started, and the two cleaning boxes 501 are adjusted to move forward or backward as a whole at the same time, so that the center lines of the two cleaning boxes 501 coincide with the street light pole, and then the drive motor 1 410 stops; the drive motor 2 411 rotates clockwise to ensure that the distance between the two cleaning boxes 501 is expanded while the center line positions of the two cleaning boxes 501 remain unchanged, and at the same time, the electric push rod 602 is started to move the cleaning box 501 as a whole to the right until the street light pole is in the center position of the cleaning box 501 and then stops, and then the drive motor 2 411 is started to rotate counterclockwise, so that the distance between the two cleaning boxes 501 gradually decreases until the bristles of the two roller brushes 504 can clean the street light pole, and the drive motor 2 411 stops rotating.

[0082] Start the cleaning motor 505 and the high-pressure water pump, and the high-pressure nozzle 507 on the spray pipe 506 begins to spray the street light pole. At the same time, the two roller brushes 504 rotate to clean the surface of the street light pole. While cleaning, start the main hydraulic cylinder 19, and the main hydraulic cylinder 19 pushes the horizontal connecting rod 20 to drive the two lifting arms 202 to rise at the same time. The lifting arm 202 drives the lifting arm 3 203 and the lifting arm 4 204 through the chain drive and the auxiliary lifting wheel 206. The fixed platform 18 at the top of the lifting arm 4 204 rises with the lifting arm 4 204, and then the cleaning box 501 rises with the lifting arm 4 204; while the cleaning box 501 rises, the roller brush 504 cleans the street light pole.

[0083] When the roller brush 504 rises to the top of the street light pole, the main hydraulic cylinder 19 is retracted, and the transverse connecting rod 20 moves downward with the retraction of the main hydraulic cylinder 19, while driving the lifting arm 2 202 to descend. The lifting arm 2 202 drives the lifting arm 3 203, the lifting arm 4 204 and the fixed platform 18 at the top of the lifting arm 4 204 through the chain transmission, thereby causing the cleaning box 501 to descend as a whole. While the cleaning box 501 descends as a whole, the street light pole is cleaned again from top to bottom until the main hydraulic cylinder 19 returns to its initial position.

[0084] When the streetlight pole is located below the bottom of the carriage for cleaning, the lifting mechanism is started, the electric hoist 205 releases the wire rope 36, and the lateral adjustment mechanism 4 and the two cleaning boxes 501 are lowered as a whole by their own gravity. When descending, the roller plate 32 moves along the inner grooves of the two lifting arms 204. At the same time, the high-pressure nozzle 507 sprays the streetlight pole, and the two roller brushes 504 clean the streetlight pole; when the roller plate 32 descends to the lowest point of the lifting arm 204, the roller plate 32 stops descending. At this time, the lifting mechanism continues to release the wire rope 36, and the outer tube 3302 on the lateral adjustment mechanism 4 continues to move toward the bottom of the carriage with the inner tube 3301 on the roller plate 32 as a track to clean the streetlight pole below the carriage; after cleaning is completed, the electric hoist 205 retracts the wire rope 36, and the wire rope 36 drives the hanging plate 401 to lift the lateral adjustment mechanism 4 upward, and the hanging plate 401 is After rising a certain distance, the top of the hanging plate 401 contacts the transverse plate 3203 of the roller plate 32, and drives the roller plate 32 to continue rising until the transverse adjustment mechanism 4 and the cleaning box 501 return to the initial position, completing the whole process of cleaning the part of the street lamp pole below the car body, and at the same time turning off the lifting mechanism, cleaning motor 505 and high-pressure water pump; starting the drive motor 2 411 to rotate clockwise, expanding the distance between the two cleaning boxes 501 to an appropriate position relative to the diameter of the street lamp pole, starting the electric push rod 602 to retract, and then starting the drive motor 2 411 to rotate counterclockwise, reducing the distance between the two cleaning boxes 501 to the initial distance and then stopping, starting the drive motor 1 410 to adjust the front and rear positions of the two cleaning boxes 501, so that the cleaning box 501 returns to the initial position, starting the hydraulic support leg 31 to retract, and starting the drive motor 9 to make the cleaning box 501 return to the car body, completing a complete cleaning process.

[0085] During the on-site street light pole cleaning process, we often encounter some tilted street light poles, such as Figure 8 、 Figure 9 As shown, take the street light pole tilted backward as an example:

[0086] First, the vehicle is controlled to stop at a position so that the streetlight pole is located between the two cleaning boxes 501, and the main hydraulic cylinder 19 is started. During the rising process of the main hydraulic cylinder 19, due to the backward tilt of the streetlight pole, the cleaning box 501 will rise and the streetlight pole will contact the buffer roller 702 at the rear side. At this time, all the limiters and collision columns are not in contact, and the two cleaning boxes 501 remain horizontal and motionless; as the cleaning box 501 continues to rise, the streetlight pole will gradually squeeze the buffer roller 702 at the rear side until the fourth collision column 719 contacts the counterclockwise rotation stop limiter 716. At this time, the drive motor 1 Without any movement, the cleaning box 501 continues to rise, and the streetlight pole continues to squeeze the rear buffer roller 702 until the third collision post 718 contacts the clockwise rotation start limiter 715, activating drive motor 1 410 to rotate clockwise, causing both cleaning boxes 501 to move backward as a whole until the streetlight pole contacts the front buffer roller 702. As the cleaning box 501 continues to move backward, the streetlight pole gradually squeezes the front buffer roller 702 until the second collision post 713 contacts the clockwise rotation stop limiter 710, causing drive motor 1 410 to stop rotating clockwise. As the cleaning box 501 continues to clean upward, the above process repeats until the cleaning box 501 reaches the top of the streetlight pole.

[0087] After the cleaning box 501 reaches the top of the backward-tilted streetlight pole, it starts to move downward under the drive of the lifting arm assembly. The specific working process is as follows:

[0088] As the cleaning box 501 descends, the streetlight pole gradually presses against the front buffer roller 702 until the second collision post 713 contacts the clockwise rotation stop limiter 710. At this point, the drive motor 1 410 does not move, and the two cleaning boxes 501 remain horizontal and stationary. The cleaning box 501 continues to descend until the first collision post 712 contacts the counterclockwise rotation start limiter 719, starting the drive motor 1 410 to rotate clockwise, causing the two cleaning boxes 501 to move forward as a whole until the streetlight pole contacts the rear buffer roller 702. The two cleaning boxes 501 continue to descend as a whole, and the streetlight pole gradually presses against the rear buffer roller 702 until the fourth collision post 719 contacts the counterclockwise rotation stop limiter 716, causing the drive motor 1 410 to stop rotating counterclockwise. As the cleaning box 501 continues to descend as a whole, the above process repeats until the cleaning box 501 reaches the bottom of the streetlight pole, completing the entire process of flushing the streetlight pole from top to bottom.

[0089] When the light pole is tilted forward, the working principle is the same as when it is tilted backward.

[0090] The present invention adds a lifting mechanism on the top of the lifting module 2, and uses the lifting mechanism to lift the cleaning module 5, so that the street light pole below the car can be cleaned, thereby expanding the cleaning area; a water baffle is added on the outside of the waste water tank at the bottom of the cleaning box to prevent the roller brush from throwing out the cleaning water during the cleaning process, so that the cleaning water can be uniformly recycled and reused; by controlling the forward and reverse rotation of the driving motor 1 on the lateral adjustment mechanism, the one-way screw rotates to drive the lateral adjustment frame to move, so that the cleaning box can be adjusted in position according to the inclination degree of the street light pole, and the inclined street light pole can be effectively cleaned.

[0091] The above is only a specific implementation method of the present invention, but the protection of the present invention is not limited to this. All equivalent changes or replacements of the technical features of the technical solution that can be thought of by technicians in this technical field are included in the protection scope of the present invention.
