[0002] Cleaning street lamps, as an important part of urban maintenance, plays an important role in ensuring the quality of road lighting and enhancing the overall image of the city. As a part of urban infrastructure, street lamps not only shoulder the heavy responsibility of night lighting, but also are an important guarantee for the beauty of the city and the sense of security of residents. Regularly cleaning street lamps can effectively remove accumulated dust and dirt, improve the lighting effect, extend the service life of street lamps, and at the same time beautify the urban environment and create a more comfortable and safe living space for citizens.

[0003] At present, for the cleaning work of high objects such as street lamps, there are already a variety of cleaning tools and technologies on the market. Most of these tools and technologies adopt mechanical or automated methods to improve cleaning efficiency and reduce manual labor intensity. Usually, air pressure and water spraying systems are used to clean street lamps.

[0004] However, the current cleaning is carried out by spraying water from the ground, which requires a large pressure to spray the water. And to meet the water pressure and flushing requirements, the water flow is also extremely large. The water pressure and water flow size are generally fixed or adjusted manually by turning the valve. No matter which method is used, for street lamps of different heights, it is difficult to control the water pressure, and it is easy to occur the situation of incomplete cleaning or damage to the street lamp due to too large water pressure. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a street lamp cleaning component for drones to solve the technical problems of large water flow waste and difficult water pressure control in the current street lamp cleaning.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A street lamp cleaning component for drones, including a frame.

The side of the frame inside away from the electric push rod is provided with a water tank, and the top of the bottom structure of the frame is provided with a water spraying flat nozzle cooperating with the water tank.

[0007] By adopting the above technical scheme, the set frame supports the whole device. The push plate is pushed by the electric push rod, the air is stored and controlled by the air cylinder, the device is adsorbed on the street lamp through the suction cup, the cleaning water is stored in the water tank, and the street lamp is cleaned by spraying water through the water spraying flat nozzle.

[0008] The utility model is further set as that one end of the electric push rod penetrating into the air cylinder is provided with a push plate, and the push plate divides the inside of the air cylinder into upper and lower two airtight spaces.

[0009] By adopting the above technical solution, the set push plate pushes the gas inside the air cylinder to form positive and negative pressure chambers.

[0010] The present utility model is further configured such that a pressure air pipe is connected between the bottom of the air cylinder and the top of the water tank, a water pipe is connected between the bottom of the water tank and the flat water spraying port, a stop rod that is slidably connected to the bottom of the air cylinder is slidably connected inside the water pipe, and a spring is connected between the stop rod and the air cylinder.

[0011] By adopting the above technical solution, the set pressure air pipe transports the gas in the air cylinder to the inside of the water tank for pressurization, transports the cleaning water in the water tank to the flat water spraying port through the water pipe, controls the closing of the water outlet end of the water pipe through the stop rod, and resets the stop rod through the spring.

[0012] The present utility model is further configured such that the part of the water pipe located at the bottom of the flat water spraying port is slidably connected to the stop rod and is perpendicular to the flat water spraying port, and this part is vertically communicated with the part connected to the water pipe.

[0013] By adopting the above technical solution, the set vertical structure enables the part of the stop rod located inside the water pipe to function as a water valve.

[0014] The present utility model is further configured such that a limiting rod that is slidably connected to the frame is provided on one side of the stop rod, and a sliding groove that cooperates with the limiting rod is formed inside the frame.

[0015] By adopting the above technical solution, the set limiting rod assists the stop rod to keep the stop rod vertically up and down, and through the cooperation of the sliding groove and the limiting rod, the limiting rod can move up and down inside the frame.

[0016] The present utility model is further configured such that an air extraction pipe is connected between the top of the air cylinder and the suction cup.

[0017] By adopting the above technical solution, when a negative pressure is formed inside the air cylinder by the set air extraction pipe, the suction cup is driven to adsorb.

[0018] The present utility model is further configured such that a fixing component is provided at the top of the frame.

[0019] By adopting the above technical solution, the set fixing component fixes the frame to a drone or other lifting device.

[0020] In summary, after the present utility model lands on the top of the street lamp, the electric push rod extends, the lower part space inside the air cylinder shrinks to form a positive pressure, and the positive pressure is transmitted to the inside of the water tank through the pressure air pipe to form a negative pressure. The negative pressure forces the cleaning water inside the water tank to enter the water pipe, and then controls the water pressure through a constant pressure and a constant distance. Since the range is short, a smaller water flow can be used for cleaning. Brief Description of the Drawings

Detailed Description of the Preferred Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0027] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0028] A street lamp cleaning component for an unmanned aerial vehicle includes a frame 1. An electric push rod 5 is arranged on one side inside the frame 1. An air cylinder 13 cooperating with the electric push rod 5 is arranged at the bottom of the electric push rod 5. A suction cup 3 cooperating with the air cylinder 13 is arranged at the bottom end of the upper structure of the frame 1. A water tank 12 is arranged on the side of the frame 1 away from the electric push rod 5. A flat water spraying nozzle 10 cooperating with the water tank 12 is arranged at the top of the bottom structure of the frame 1.

[0029] When in use, this device can be installed at the bottom of the unmanned aerial vehicle or fixed by using other controllable lifting devices. Exemplarily, this component is installed at the bottom of a six-rotor unmanned aerial vehicle; in another example, this device is installed at the top of a manually controlled telescopic boom.

[0030] After installation and fixation, according to the usage requirements, a mobile platform is generally used as a carrier. Exemplarily, a modified special cleaning vehicle for municipal roads is used. The vehicle body is equipped with a water tank for supplying water to the water tank 12 of this device, and can be equipped with devices such as a charging interface.

[0031] The following example uses the installation of a drone as an example. When using other fixing methods, the main working steps are similar, but the specific moving operations are slightly different, and the corresponding installation carrier should be used as a reference.

[0032] After moving to the vicinity of the street lamp to be cleaned, the water tank 12 of the drone is filled with cleaning water. Optionally, a water inlet pipeline penetrating to the outside of the bottom of the frame 1 is provided at the bottom of the water tank 12, and a one-way valve is provided inside the pipeline. When the electric push rod 5 is reset, a negative pressure is formed inside the water tank 12. At this time, in cooperation with the water pool of the carrier platform, the bottom of the device is placed in the water pool, and the water tank 12 is filled by suction using the negative pressure.

[0033] After the water injection is completed, the drone moves the device to the height of the street lamp, puts the street lamp into the middle of the frame 1, and slowly descends so that the suction cup 3 fits with the top of the street lamp. At this time, it is worth mentioning that when facing a special shape that causes the suction cup 3 to be unable to adsorb, multiple groups of small suction cups 3 or a telescopic arm can be used as a fixing carrier.

[0034] After landing on the top of the street lamp, the electric push rod 5 extends. At this time, since the push plate 7 divides the inside of the air cylinder 13 into upper and lower two airtight spaces, as the push plate 7 moves downward, the upper part of the space inside the air cylinder 13 increases to form a negative pressure, and the lower part of the space decreases to form a positive pressure. The negative pressure is transmitted to the suction cup 3 through the suction pipe 4, generating a negative pressure on the space formed between the suction cup 3 and the top of the street lamp cover for adsorption. The positive pressure in the lower part is transmitted to the water tank 12 through the pressure air pipe 6 to form a negative pressure. The negative pressure forces the cleaning water inside the water tank 12 to enter the water pipe 11.

[0035] When the push plate 7 moves to the bottom of the air cylinder 13, the air pressure inside the water tank 12 increases to the cleaning pressure. At the same time, the push plate 7 touches the bottom stop rod 9, and the part of the stop rod 9 located inside the water pipe 11 moves downward, thus relieving the blockage of the water pipe 11, enabling the water pipe 11 to release the pressure inside the water tank 12. At this time, the cleaning water is pumped into the flat nozzle 10 under the push of the pressure inside the water tank 12 and then sprayed to clean the bottom surface of the street lamp.

[0036] After spraying, the electric push rod 5 resets to drive the push plate 7 to reset, and at the same time, the stop rod 9 resets under the action of the spring.

[0037] The present utility model is further configured such that one end of the electric push rod 5 penetrating into the air cylinder 13 is provided with a push plate 7, and the push plate 7 divides the inside of the air cylinder 13 into upper and lower two airtight spaces, and the gas inside the air cylinder 13 is pushed by the provided push plate 7 to form positive and negative pressure chambers.

[0038] The present utility model is further configured such that a pressure air pipe 6 is connected between the bottom of the air cylinder 13 and the top of the water tank 12. The gas in the air cylinder 13 is conveyed into the interior of the water tank 12 through the provided pressure air pipe 6 for pressurization. A water pipe 11 is connected between the bottom of the water tank 12 and the flat water spraying opening 10. The cleaning water in the water tank 12 is conveyed to the flat water spraying opening 10 through the water pipe 11. A stop rod 9 which is slidably connected to the bottom of the air cylinder 13 is slidably connected inside the water pipe 11. The closing of the water outlet end of the water pipe 11 is controlled by the stop rod 9. A spring is connected between the stop rod 9 and the air cylinder 13, and the stop rod 9 is reset by the spring.

[0039] The present utility model is further configured such that the part of the water pipe 11 located inside the bottom of the flat water spraying opening 10 is slidably connected to the stop rod 9 and is perpendicular to the flat water spraying opening 10. Through the provided vertical structure, the part of the stop rod 9 located inside the water pipe 11 functions as a water valve, and the part connected to the water pipe 11 is vertically communicated.

[0040] The present utility model is further configured such that a limiting rod 8 which is slidably connected to the frame 1 is provided on one side of the stop rod 9. The stop rod 9 is assisted by the provided limiting rod 8 to keep it vertically up and down. A sliding groove matched with the limiting rod 8 is formed inside the frame 1. Through the cooperation of the sliding groove and the limiting rod 8, the limiting rod 8 can move up and down inside the frame 1.

[0041] The present utility model is further configured such that an air extraction pipe 4 is connected between the top of the air cylinder 13 and the suction cup 3. When a negative pressure is formed in the air cylinder 13 through the provided air extraction pipe 4, the suction cup 3 is driven to adsorb.

[0042] The present utility model is further configured such that a fixing assembly 2 is provided on the top of the frame 1. The frame 1 is fixed to a drone or other lifting devices through the provided fixing assembly 2.
